FOURTH SUPPLEMENTAL INDENTURE, dated as of May 10, 2013 (this “Fourth Supplemental Indenture”), to the Indenture, dated as of August 14, 2009, as amended by the Second Supplemental Indenture, dated as of August 4, 2011 (the “Original Indenture”), between HYATT HOTELS CORPORATION, a corporation organized under the laws of Delaware (the “Company”), and WELLS FARGO BANK, NATIONAL ASSOCIATION, a national banking association organized under the laws of the United States, as trustee (the “Trustee”).

WHEREAS, Section 9.01(10) of the Original Indenture provides that the Company and the Trustee may amend or supplement the Original Indenture without consent of any Holder to add to, change or eliminate any of the provisions of the Original Indenture with respect to one or more Series of Notes, so long as any such addition, change or elimination shall (A) neither apply to any Note of any Series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor modify the rights of the Holders of any such Note with respect to the benefit of such provision or (B) become effective only when there is no such Note outstanding; and

WHEREAS, all action on the part of the Company necessary to authorize this Fourth Supplemental Indenture has been duly taken;

NOW, THEREFORE, THIS INDENTURE WITNESSETH:

That, in consideration of the premises set forth above, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE I

SECTION 1.01. Amendment to Section 9.02. With respect to (and solely with respect to) any Series of Notes created after the execution of this Fourth Supplemental Indenture, Section 9.02 of the Original Indenture is hereby deleted and amended and restated in its entirety to read as follows:

The Company and the Trustee may amend or supplement this Indenture or the Notes of any Series without notice to any Holder but with the written consent of the Holders of at least a majority in principal amount of the Notes of each Series then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes) affected by such amendment or supplement by execution of a supplemental indenture hereto. However, without the consent of each Holder affected, an amendment or supplement may not:

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the rate of or extend the time for payment of interest, including default interest, on any Note;

(3) reduce the principal of or change the Stated Maturity of any Note;

(4) reduce the amount payable upon the redemption of any Note or change the time of any mandatory redemption or, in respect of an optional redemption, the times at which any Note may be redeemed (excluding, for the avoidance of doubt, the number of days before a redemption date that a notice of redemption may be mailed to the holders) or, once notice of redemption has been given to the holders, the time at which it must thereupon be redeemed;

(5) make any Note payable in money other than that stated in the Note;

(6) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(7) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to receive payments of principal of, or premium, if any, or interest on the Notes;

(8) waive a redemption payment with respect to any Note; or

(9) make any change in Section 6.04 or 6.07 hereof or in the foregoing amendment and waiver provisions.

It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment or supplement, but it shall be sufficient if such consent approves the substance thereof. After an amendment or supplement under this Section becomes effective, the Company shall mail to all affected Holders a notice briefly describing such amendment or supplement. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment or supplement under this Section.
