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 ▇▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, 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 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 ▇▇▇▇▇ 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

(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 ▇▇▇▇▇▇▇▇ 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:

(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.

(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.

(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,

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.

(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 ▇▇▇▇▇’▇ 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 ▇▇▇▇▇’▇ board of directors, unless at least one Independent director did not approve the transaction.
