Execution Copy

AMENDED AND RESTATED GLOBAL HYATT AGREEMENT

Amended and Restated Global Hyatt Agreement (this “Agreement”), dated as of October 1, 2009, by, between and among each of Thomas J. Pritzker, Marshall E. Eisenberg and Karl J. Breyer, not individually, but in their capacity as trustees (in such capacity, each a “Trustee” and, collectively, the “Trustees”) and each of the other 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 Trustees and the Adult Beneficiaries are party to the 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 Trustees are the current trustees of each of the 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 the direct and/or indirect owners of a majority of the common equity interests in Hyatt Hotels Corporation, a Delaware corporation (“Hyatt”);

WHEREAS, in the context of the creation of liquidity, the Trustees and the Adult Beneficiaries have determined it to be in their collective best interests to effect a restructuring of the Hyatt Owning Trusts’ interests in Hyatt and, accordingly, the Trustees will seek to create 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 Trustees and 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 I

Section 1.1 Effective Time. This Agreement and the obligations of the parties hereto shall become effective for all purposes and respects as of the time the registration statement with respect to the IPO is declared effective by the Securities and Exchange Commission (the “Effective Time”); provided, that, if the IPO is not consummated within ten business days of the Effective Time, this Agreement shall automatically terminate and be deemed never to have had any force or effect.

ARTICLE II

    (b) This Agreement has been duly and validly executed by such party and, upon delivery thereof by such party, will constitute a legal, valid and binding obligation of such party enforceable against such party in accordance with its terms.

    (c) The execution, delivery and performance of this Agreement by such party in compliance with the terms and provisions hereof will not, to the best of such party’s knowledge, conflict with, result in a breach of, or constitute a violation or default of or give any third party the right to terminate, accelerate or modify any obligation under, (i) any material agreement or other document or instrument to which such party is bound or affected or (ii) any law, statute, rule, regulation, ordinance, writ, order or judgment to which such party is bound or affected.

ARTICLE III

Voting Agreement; Disposition of Securities

Section 3.1 IPO. At the Effective Time, the following provisions shall become and be effective provided that Hyatt Common Stock continues to be Public:

    (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 Foreign Pritzkers, all Pritzkers and Foreign 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 Foreign 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 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 Foreign Pritzkers, all Pritzkers (and their successors in interest, if applicable), but not the transferees by sale (other than Pritzkers or Foreign Pritzkers who purchase directly from other Pritzkers or Foreign Pritzkers) or by, or following, foreclosures as aforesaid, will vote all of their voting securities of Hyatt (and successor Companies) 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 Trustees have notified the Current Adult Beneficiaries of their intention to distribute Hyatt Common Stock and have 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 Trustees hereby acknowledge and agree that it is in the best interests of the Adult Beneficiaries to distribute Hyatt stock from the Ancestor Trusts as soon as practicable following the Effective Time and, accordingly, shall 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.

ARTICLE IV

Arbitration

Section 4.1 Scope of Arbitration.

    (a) Except as otherwise expressly provided in this Agreement, disputes between or among any of the parties hereto, and/or disputes between or among any of the parties hereto and any Person who has executed a Joinder (to the extent any such disputes among the parties and/or among the parties and Persons who executed Joinders relate directly to the subject matter of this Agreement), shall be determined solely and exclusively by arbitration in accordance with this Article IV, which shall be broadly construed in favor of arbitrability of all such disputes, including, without limitation, any dispute, controversy, claim or other issue arising out of or relating to:

    (i) The existence, validity, interpretation, construction, enforcement, breach, termination or rescission of this Agreement;

    (ii) The actions or failures to act of any party to this Agreement with respect to this Agreement;

    (iii) Dispute resolution under this Agreement, including arbitrability; or

    (iv) All other matters directly related to the subject matter of this Agreement.

    (b) In any arbitration, this Agreement and all other documentation determined by the Arbitrator to be relevant shall be admissible in evidence. In deciding any issue submitted to arbitration, the Arbitrator shall consider the rights, powers and obligations of the Trustees (or their predecessors) in light of this Agreement, the relevant trust instruments, and Illinois law.

    Section 4.2 Rules; Location.

    (a) Except as otherwise provided herein, the Commercial Arbitration Rules of the American Arbitration Association in effect as of the Effective Time shall govern any arbitration hereunder, but such arbitration shall not be conducted under the auspices of the American Arbitration Association.

        (b) All arbitrations shall be held in Chicago, Illinois, at a site or sites determined by the Arbitrator.

Section 4.3 Arbitrator.

    (a) All arbitrations will be before a single arbitrator (the “Arbitrator”), who shall be Independent, have a respected legal background, and be selected in accordance with this Section.

    (b) The parties agree that the initial Arbitrator shall be Michael Sovern.

    (c) Mr. Sovern shall nominate a successor Arbitrator who shall become the successor Arbitrator upon (i) approval of six of the Current Adult Beneficiaries and (ii) the execution and delivery by such individual of a Joinder in reasonably acceptable form.

    (d) Each successor Arbitrator shall appoint a subsequent successor who satisfies the criteria described in Section 4.3(a), and in the absence thereof, and notwithstanding the provisions of Section 4.2(a) hereof, the successor Arbitrator shall be selected by the American Arbitration Association pursuant to Section L-3 of the Optional Procedures for Large Complex Commercial Disputes of the Commercial Arbitration rules of the American Arbitration Association (or any successor provision).

    (e) Once an Arbitrator is identified as provided above, all parties to this Agreement and their counsel, Joined Agents and other representatives will refrain from all ex parte contacts with the Arbitrator.

    Section 4.4 Demand for and Action to Compel Arbitration.

    (a) To demand arbitration hereunder, the party seeking arbitration shall be required to deliver written notice to the Arbitrator (when and if available) and each of the Trustees and all parties in respect of whom arbitration is sought, specifying in reasonable detail the issue or issues to be arbitrated. 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) Nothing herein shall be deemed to impair the right of any party to seek an order of any court of competent jurisdiction compelling arbitration or in aid of the jurisdiction of the Arbitrator.

Section 4.5 Confidentiality.

    (a) Except as may be required by applicable law and for communications among the parties to this Agreement and their respective counsel (and Persons retained by counsel for the purpose of assisting in any proceeding, who shall agree to be bound by a reasonable confidentiality agreement), all arbitration proceedings commenced hereunder, and all demands, pleadings, briefs or other documents relating to such proceedings, as well as any decisions or awards of the Arbitrator (except insofar as may be necessary to obtain judicial confirmation and/or enforcement of such decision or award), shall be completely and permanently confidential and shall not be communicated to third parties, and the Arbitrator will so order.

    (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, and shall be final and binding on the parties to this Agreement in all respects and for all purposes (without any right of appeal).

    (b) 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 (including the payment thereof from one or more Hyatt Owning Trusts, as appropriate), and non-monetary sanctions (but not Consequential Damages, punitive damages, exemplary damages or multiple damages).

    (c) Notwithstanding any other provision of this Agreement, the Arbitrator shall not render any monetary award against a Trustee personally in the absence of a finding that such Trustee has willfully, materially and in bad faith breached his fiduciary duty. Any such monetary award shall be for actual and/or compensatory damages, and not for Consequential Damages, punitive damages, exemplary damages, or multiple damages.

    (d) A party to an arbitration shall have the right to petition a court of competent jurisdiction located in Chicago, Illinois 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.
