AMENDED AND RESTATED FOREIGN GLOBAL HYATT AGREEMENT

Amended and Restated Foreign Global Hyatt Agreement (this “Agreement”), dated as of October 1, 2009, by and among each of the signatories hereto (each, an “Adult Beneficiary” and, collectively, the “Adult Beneficiaries”). Each beneficiary of a Hyatt Owning Trust who attains the age of 18 following the date hereof and executes a Joinder shall also be deemed to be an “Adult Beneficiary” for purposes of this Agreement.

WHEREAS, the Adult Beneficiaries are party to the Foreign Global Hyatt Agreement dated as of March 12, 2008 (the “Original Agreement”) and have determined that it is in their collective best interests to amend and restate the Original Agreement in its entirety;

WHEREAS, the Trustee is the trustee of each of the non-United States situs trusts for the benefit of descendants of Nicholas J. Pritzker, deceased, identified on Exhibit A hereto (collectively, the “Hyatt Owning Trusts”);

WHEREAS, the Adult Beneficiaries are current and/or contingent beneficiaries of the Hyatt Owning Trusts who have reached the age of eighteen years;

WHEREAS, the Hyatt Owning Trusts are indirect owners of common equity interests in Hyatt Hotels Corporation, a Delaware corporation (“Hyatt”);

WHEREAS, in the context of the creation of liquidity, the Adult Beneficiaries have determined that it would be in their collective best interests if the Trustee caused an overall business plan to be effectuated with respect to the Hyatt Owning Trusts’ interests in Hyatt and, accordingly, desire that the Trustee seek to cause the creation of a liquid market for the common equity securities in Hyatt through an initial public offering of the common stock (“Hyatt Common Stock”) of Hyatt registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and anticipated to be listed on the New York Stock Exchange (the “IPO”);

WHEREAS, the Board of Directors and stockholders of Hyatt have approved an Amended and Restated Certificate of Incorporation (the “A/R COI”), which will become effective prior to the consummation of the IPO and provides, among other things, for the authorization of, and the reclassification of issued and outstanding shares of common stock of Hyatt into Class A common stock entitled to one vote per share (“Class A Common Stock”) and Class B common stock entitled to ten votes per share (“Class B Common Stock”) as specified in the A/R COI;

WHEREAS, it is anticipated that in connection with the IPO, the Class A Common Stock will be registered under the Exchange Act and listed on the New York Stock Exchange and shall constitute Hyatt Common Stock for all purposes hereunder; and

WHEREAS, in order to facilitate the consummation of the IPO, the Adult Beneficiaries find it to be in the best interests of all of the parties hereto to enter into this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and for other good and valuable consideration, the receipt, adequacy and sufficiency of

which are hereby acknowledged, the parties, intending legally to be bound, hereby agree to amend and restate the Original Agreement as follows:

ARTICLE III

Voting Agreement; Disposition of Securities

Section 3.1 IPO. At the Effective Time, and provided that Hyatt Common Stock continues to be Public, the beneficiaries of the Hyatt Owning Trusts shall (and agree that the Pritzkers shall and desire that the Trustee shall) act in accordance with the following provisions

as to any shares of Hyatt Common Stock that the Pritzkers directly or indirectly own (and the Adult Beneficiaries shall inform the Trustee thereof):

(a) Until the later to occur of (i) January 1, 2015 and (ii) that date upon which more than 75% of the FD Stock is owned by Persons other than Pritzkers and Domestic Pritzkers, all Pritzkers and Domestic Pritzkers in a Beneficiary Group (including trusts only to the extent of the then current benefit of members of such Beneficiary Group) will be free to sell up to 25% of their aggregate holdings of Hyatt, measured as of the Effective Time, in each 12 month period following the Effective Time (without carry-overs), and shall not sell more than such amount during any such period; provided, however, upon the unanimous affirmative vote of the Independent directors of Hyatt, such 25% limitation may, with respect to such 12 month period, be increased to a higher percentage or waived entirely and provided further, that sales of Hyatt Common Stock, including Class A Common Stock and Class B Common Stock, between and among Pritzkers and/or Domestic Pritzkers shall be permitted without regard to the sale restrictions in this Section 3.1(a), and such sales shall not be counted against the 25% limitation described herein.

(b) Notwithstanding anything to the contrary contained herein or contained in any other agreement among the parties hereto, all the shares in Hyatt owned directly or indirectly by each Beneficiary Group (including trusts only to the extent of the then current benefit of members of such Beneficiary Group) will be freely pledgeable to an institutional lender (commercial bank, insurance company, brokerage or the like), which institutional lender will not be subject to sale restrictions upon default and foreclosure.

(c) Until the later to occur of (i) January 1, 2015 and (ii) that date upon which more than 75% of the FD Stock is owned by Persons other than Pritzkers and Domestic Pritzkers, all Pritzkers (and their successors in interest, if applicable), but not the transferees by sale (other than Pritzkers or Domestic Pritzkers who purchase directly from other Pritzkers or Domestic Pritzkers) or by, or following, foreclosures as aforesaid, will vote (or cause to be voted) all of the voting securities of Hyatt (and successor Companies) held directly or indirectly by them consistent with the recommendations of the board of directors of Hyatt with respect to all matters (assuming agreement as to any such matter by a majority of a minimum of three Independent directors or, in the case of transactions involving Hyatt and an Affiliate thereof, assuming agreement of all of such minimum of three Independent directors). All Pritzkers will cast and submit by proxy to Hyatt their votes in a manner consistent with this Section 3.1(c) at least five business days prior to the scheduled date of the Annual or Special Meeting of stockholders of Hyatt, as applicable.

(d) After the Trustee has notified the Current Adult Beneficiaries of its intention to distribute Hyatt Common Stock and has commenced consultation with them as to the structure of such distribution, no Current Adult Beneficiary shall, until the earlier of (i) six months from the date of such notification and (ii) the date of distribution of such Hyatt Common Stock, acquire either directly, or indirectly for his exclusive benefit, any “derivative securities” (as defined in Rule 16a-1(c) of the Exchange Act) with respect to such Hyatt Common Stock. The Adult Beneficiaries hereby acknowledge and agree that it is in the best interests of the Adult Beneficiaries for the Trustee to distribute Hyatt stock from the Ancestor Trusts as soon as practicable following the Effective Time and, accordingly, shall inform the Trustee that it is the

Adult Beneficiaries’ desire that the Trustee distribute such stock in consultation with the Adult Beneficiaries as soon as practicable following the Effective Time subject to the underwriter’s 180-day “lock-up” agreement related to the IPO to which such stock is subject.

Upon receipt of such notice, the Arbitrator shall commence, conduct and conclude all proceedings within a reasonable time. Notwithstanding anything to the contrary contained in this Agreement, no party may demand arbitration subsequent to the date that is ninety (90) days following the date upon which the voting agreement set forth in Article III hereof expires by its terms.

(b) Any party initiating judicial proceedings to compel arbitration or to confirm an award of the Arbitrator shall in good faith seek an order providing for the filing of all pleadings and arbitration documents under seal and all of the parties shall agree thereto.

(c) No tape or electronic recording or transcripts of arbitration proceedings shall be retained by any party after the completion of the arbitration proceeding; provided, however, that the Arbitrator (and any successor Arbitrators) may retain such records as he deems useful to the discharge of his duties hereunder and the Arbitrator may make any recordings or transcripts available upon request of a party to a subsequent arbitration pursuant to this Article (and solely for use in such subsequent arbitration) at his discretion and upon terms and conditions the Arbitrator deems appropriate.

Section 4.6 Discovery and Conduct of Hearing.

(a) The parties to any arbitration hereunder shall be entitled to such pre-hearing discovery, if any, as may be determined by the Arbitrator.

(b) In conducting the arbitration, the Arbitrator may act in summary fashion, upon submission of papers, or in plenary fashion, in his discretion.

Section 4.7 Form of Award; Remedies; Confirmation.

(a) An award of the Arbitrator shall be in writing and signed by him, shall not include findings of fact, conclusions of law, or other matters of opinion, shall state as briefly as possible the determination of the issue or issues submitted; provided, however, that the Arbitrator may make findings of fact and/or conclusions of law if and to the extent necessary to render the award valid and enforceable. The Arbitrator’s award shall be final and binding on the parties to this Agreement in all respects and for all purposes (without any right of appeal).

(b) Except as may otherwise be provided herein, the Arbitrator shall be authorized to award any form of relief as may be appropriate, consistent with the Commercial Arbitration Rules of the American Arbitration Association, including immediate, interim and/or final equitable relief, compensatory damages, fees, costs and expenses of the arbitration proceeding and non-monetary sanctions (but not Consequential Damages, punitive damages, exemplary damages or multiple damages).

(c) A party to an arbitration shall have the right to petition a court of competent jurisdiction for an order confirming the Arbitrator’s award.

Section 4.8 Certain Arbitrations. The exclusive requirement to arbitrate hereunder shall not apply with respect to the manner in which Hyatt’s operations are conducted to the extent the parties (in their capacities as shareholders) and non-Pritzker public shareholders are affected comparably; provided, however, that a party may participate in and benefit from any shareholder litigation initiated by a non-party. A party may not solicit others to initiate or be a named plaintiff in such litigation, (i) unless two thirds of the Independent directors of a board of directors having at least three Independent directors do not vote in favor of the matter that is the subject of the litigation or (ii), in the case of affiliated transactions reviewed by Hyatt’s board of directors, unless at least one Independent director did not approve the transaction.
