Schedule 13D

(Name, Address and Telephone Number of Person Authorized to Receive Notices and Communications)

If the filing person has previously filed a statement on Schedule 13G to report the acquisition that is the subject of this Schedule 13D, and is filing this schedule because of §§240.13d-1(e), 240.13d-1(f) or 240.13d-1(g), check the following box. ¨

The information required in the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934 (“Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

* Represents shares of the Issuer’s Class A Common Stock, $0.01 par value per share (the “Class A Common Stock”), issuable upon conversion of shares of the Issuer’s Class B Common Stock, $0.01 par value per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”). As provided in the Issuer’s Amended and Restated Certificate of Incorporation, each share of Class B Common Stock is convertible at any time, at the option of the holder, into one share of Class A Common Stock.

The Reporting Persons (as defined in this Schedule 13D) are party to certain agreements with the Separately Filing Group Members (as defined in this Schedule 13D), which agreements contain, among other things, certain voting agreements and limitations on the sale of their shares of Common Stock. As a result, the Reporting Persons may be deemed to be members of a “group,” within the meaning of Section 13(d)(3) of the Act (as defined in this Schedule 13D), comprised of the Reporting Persons and the Separately Filing Group Members. Shares listed as beneficially owned by each Reporting Person exclude shares held by any other Reporting Person or by any of the Separately Filing Group Members, in each case as to which the Reporting Person disclaims beneficial ownership.

All references to the number of shares outstanding are as of July 31, 2010, as reported in the Issuer’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2010, as adjusted to account for 539,588 shares of Class B Common Stock that were converted into shares of Class A Common Stock in connection with the Distribution (as defined in this Schedule 13D). The percentage is calculated using the total number of shares of Common Stock beneficially owned by the Reporting Persons and based on 173,922,706 shares of Common Stock outstanding as of July 31, 2010. With respect to matters upon which the Issuer’s stockholders are entitled to vote, the holders of Class A Common Stock and Class B Common Stock vote together as a single class, and each holder of Class A Common Stock is entitled to one vote per share and each holder of Class B Common Stock is entitled to ten votes per share. The shares of Class B Common Stock owned by the Reporting Persons represent 3.8% of the total voting power of the Common Stock as of July 31, 2010, as adjusted. The percentage of total voting power of the Common Stock is calculated based on the total voting power of the Common Stock outstanding as of July 31, 2010, as adjusted, which is comprised of 44,456,706 shares of Class A Common Stock and 129,466,000 shares of Class B Common Stock and assumes that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock.

EXPLANATORY NOTE: This Schedule 13D is being filed by the Reporting Persons (as defined in Item 2 below) pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Act”), and Rule 13d-1(a) thereunder, with respect to the shares of Class A Common Stock, $0.01 par value per share (the “Class A Common Stock”), of Hyatt Hotels Corporation, a Delaware corporation (the “Issuer”), held by the Reporting Persons, including shares of Class A Common Stock issuable upon conversion of shares of the Issuer’s Class B Common Stock, $0.01 par value per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”). As provided in the Issuer’s Amended and Restated Certificate of Incorporation, each share of Class B Common Stock is convertible at any time, at the option of the holder, into one share of Class A Common Stock. The Reporting Persons are party to certain agreements with the Separately Filing Group Members (as defined in Item 2 below), which agreements contain, among other things, certain voting agreements and limitations on the sale of their shares of Common Stock. As a result, the Reporting Persons may be deemed to be members of a “group”, within the meaning of Section 13(d)(3) of the Act, comprised of the Reporting Persons and the Separately Filing Group Members (collectively, the “Pritzker Family Group”).

The shares of Common Stock held by the Reporting Persons were previously reported on a Schedule 13G filed on November 4, 2009, as amended, pursuant to Section 13(g) of the Act and Rule 13d-1(d) thereunder.

On August 17, 2010, the Reporting Persons either allocated or distributed, in the aggregate, 75,978,487 shares of Class B Common Stock to certain of the Separately Filing Group Members. In addition, on August 17, 2010, IHE distributed, in the aggregate, 23,765,141 shares of Class B Common Stock to CIBC Trust Company (Bahamas) Limited, solely in the capacity as trustee of non-U.S. situs trusts for the benefit of certain lineal descendants of Nicholas J. Pritzker, deceased (the “Non-U.S. Situs Trusts”), certain of the other Separately Filing Group Members and certain other persons, and the trustee of the Non-U.S. Situs Trusts and certain other members of IHE allocated or distributed, in the aggregate, 18,025,104 shares of Class B Common Stock previously held by IHE and its subsidiaries to certain of the Separately Filing Group Members and certain other persons. We refer to all of the above allocations and distributions, collectively, as the “Distribution.” Contemporaneous with the Distribution, certain of the Separately Filing Group Members executed joinders to, and thereby became subject to the provisions of, the agreements described in Item 6 below. The Distribution to the Separately Filing Group Members qualified as a “Permitted Transfer” for purposes of the Issuer’s Amended and Restated Certificate of Incorporation and, accordingly, the shares of Class B Common Stock allocated or distributed to the Separately Filing Group Members remained shares of Class B Common Stock immediately following the Distribution. Certain other persons who received shares in the Distribution are not party to the agreements described in Item 6 below and their shares were converted into shares of Class A Common Stock in connection with the Distribution. The Separately Filing Group Members may be deemed to have become beneficial owners of the shares of Class A Common Stock issuable upon conversion of the shares of Class B Common Stock received in the Distribution, pursuant to Section 13(d) of the Act and Rule 13d-1(a) thereunder, resulting in the obligation to file this Schedule 13D. It is the understanding of the Reporting Persons that the Separately Filing Group Members are filing separate Schedule 13Ds pursuant to Rule 13d-1(k)(2) under the Act with respect to the shares of Common Stock beneficially owned by the Separately Filing Group Members.

This Schedule 13D relates to the Class A Common Stock, $0.01 par value per share, of the Issuer. The address of the principal executive office of the Issuer is 71 South Wacker Drive, 12th Floor, Chicago, Illinois 60606.

(a)-(c) This Schedule 13D is being filed by Thomas J. Pritzker, Marshall E. Eisenberg and Karl J. Breyer (the “Reporting Persons”), not individually, but solely in the capacity as co-trustees of the U.S. situs trusts for the benefit of certain lineal descendants of Nicholas J. Pritzker, deceased, listed on Appendix A (the “U.S. Situs Trusts”).

The address of the principal business and principal office of the Reporting Persons is 71 South Wacker Drive, 46th Floor, Chicago, Illinois 60606. The Reporting Persons are principally engaged in the business of investing the assets of the trusts for the benefit of the beneficiaries of such trusts.

The Reporting Persons have entered into a Joint Filing Agreement, dated as of August 26, 2010, a copy of which is attached as Exhibit 1 to this Schedule 13D.

The Reporting Persons may be deemed to be members of a “group,” within the meaning of Section 13(d)(3) of the Act, comprised of the Reporting Persons and the other persons referred to on Schedule B attached to this Schedule 13D (the “Separately Filing Group Members”). It is the understanding of the Reporting Persons that the Separately Filing Group Members are filing separate Schedule 13Ds pursuant to Rule 13d-1(k)(2) under the Act. Schedule B attached to this Schedule 13D sets forth certain information concerning the Separately Filing Group Members, which information is based solely on the information contained in the Schedule 13Ds filed by the Separately Filing Group Members.

(d) During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, none of the Reporting Persons has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

The Reporting Persons held their shares of Common Stock prior to the initial public offering (the “IPO”) of the Class A Common Stock. The Reporting Persons acquired their shares of Common Stock from time to time prior to the IPO using cash or other assets of the U.S. Situs Trusts.

The Reporting Persons held shares of the Common Stock prior to the IPO. The Reporting Persons allocated or distributed, in the aggregate, 75,987,487 shares of Class B Common Stock to certain of the Separately Filing Group Members in the Distribution, which was completed on August 17, 2010.

The Reporting Persons hold their shares of Common Stock for investment purposes. Pursuant to the agreements described in Item 6 below, the shares of Common Stock held by the Reporting Persons are currently required to be voted consistent with the recommendations of the board of directors of the Issuer 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 the Issuer and an affiliate, assuming agreement of all of such minimum of three independent directors) and are subject to certain transfer and various other restrictions. The Reporting Persons expect to routinely monitor the performance of their investment in the Issuer. In this regard, the Reporting Persons expect to evaluate on a periodic basis the Issuer’s business, financial condition and results of operation, as well as other factors that may be relevant to their investment in the Issuer. In addition, the Reporting Persons may seek the views of, hold active discussions with and respond to inquiries from representatives of the Issuer, the Separately Filing Group Members and other persons regarding the Issuer. Subject to their obligations under the agreements described in Item 6 below, the Reporting Persons may, at any time and from time to time, purchase additional shares of Common Stock or dispose of any shares of Common Stock held by them. Any additional shares of Common Stock acquired by the Reporting Persons will be subject to the agreements described in Item 6 below, for so long as those agreements remain in effect.

Except as described in this Item 4, the Reporting Persons currently have no plans or proposals that relate to or would result in any transaction, event or action set forth in subsections (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons reserve the right to formulate plans or make proposals, and take such action with respect thereto, including any or all of the items set forth in subsections (a) through (j) of Item 4 of Schedule 13D and any other actions, as they may determine.

(a)-(b) As of the date hereof, the Reporting Persons may be deemed to be the beneficial owners of 5,149,874 shares of Class A Common Stock, issuable upon conversion of 5,149,874 shares of Class B Common Stock beneficially owned by the Reporting Persons. The number of shares of Class B Common Stock beneficially owned by the Reporting Persons represents 4.0% of the total number of shares of Class B Common Stock outstanding. The number of shares of Common Stock beneficially owned by the Reporting Persons represents 3.0% of the total number of shares of Common Stock outstanding and 3.8% of the total voting power of the shares of Common Stock outstanding, voting together as a single class, assuming that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock.

Schedule A sets forth, as of the date hereof, the number of shares and percentage of the Class A Common Stock outstanding, the number of shares and percentage of the Class B Common Stock outstanding, the percentage of the total number of shares of Common Stock outstanding, and the percentage of the total voting power of the shares of Common Stock outstanding, voting together as a single class, represented by the shares beneficially owned by each Reporting Person.

Based solely on the information contained in the Schedule 13Ds filed by the Separately Filing Group Members, as set forth in Schedule B described below, as of the date hereof, the Pritzker Family Group in the aggregate may be deemed to be the beneficial owners of 10,121 shares of currently issued Class A Common Stock and 104,353,914 shares of Class A Common Stock issuable upon conversion of 104,353,914 shares of Class B Common Stock beneficially owned by the Pritzker Family Group. The number of shares of Class A Common Stock beneficially owned by the Pritzker Family Group and currently issued represents less than 0.1% of the total number of shares of Class A Common Stock outstanding, assuming that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock. The number of shares of Class B Common Stock beneficially owned by the Pritzker Family Group represents 80.6% of the total number of shares of Class B Common Stock outstanding.

Schedule B sets forth, as of the date hereof, the number of shares and percentage of the Class A Common Stock outstanding, the number of shares and percentage of the Class B Common Stock outstanding, the percentage of the total number of shares of Common Stock outstanding, and the percentage of the total voting power of the shares of Common Stock outstanding, voting together as a single class, represented by the shares beneficially owned by each Separately Filing Group Member. All such information is based solely on the information contained in the Schedule 13Ds filed by the Separately Filing Group Members.

All references to the number of shares outstanding are as of July 31, 2010, as reported in the Issuer’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2010, as adjusted to account for 539,588 shares of Class B Common Stock that were converted into shares of Class A Common Stock in connection with the Distribution. The information set forth in this Schedule 13D, including Schedule A and Schedule B hereto, with respect to the percentage of shares of Class A Common Stock beneficially owned is based on 44,456,706 shares of Class A Common Stock outstanding as of July 31, 2010, as adjusted, assuming that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock. The information with respect to the percentage of shares of Class B Common Stock beneficially owned is based on 129,466,000 shares of Class B Common Stock outstanding as of July 31, 2010, as adjusted. Each share of Class B Common Stock is convertible at any time into one share of Class A Common Stock. The information shown with respect to the percentage of total Common Stock beneficially owned is based on 173,922,706 shares of Common Stock outstanding as of July 31, 2010. The information with respect to the percentage of total voting power is based on 44,456,706 shares of Class A Common Stock and 129,466,000 shares of Class B Common Stock outstanding as of July 31, 2010, as adjusted, and assumes that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock.

Each Reporting Person disclaims beneficial ownership of the shares held by any other Reporting Person or any of the Separately Filing Group Members. The filing of this Schedule 13D shall not be construed as an admission that any of the Reporting Persons are, for purposes of Section 13(d) of the Act or otherwise, the beneficial owner of shares held by any other Reporting Person or any of the Separately Filing Group Members.

(c) The Reporting Persons allocated or distributed, in the aggregate, 75,978,487 shares of Class B Common Stock to certain of the Separately Filing Group Members in the Distribution, which was completed on August 17, 2010. See the Explanatory Note above for a description of the Distribution.

The Reporting Persons, together with certain other members of the Pritzker Family Group, are parties to the Global Hyatt Agreement (as defined below), the Agreement Relating to Stock (as defined below), and the 2009 Registration Rights Agreement (as defined below) relating to the Common Stock of the Issuer.

On October 1, 2009, the Reporting Persons and the adult beneficiaries of the U.S. Situs Trusts, entered into the Amended and Restated Global Hyatt Agreement (the “Global Hyatt Agreement”) pursuant to which they agreed to, among other things, certain voting agreements and limitations on the sale of shares of the Common Stock. Contemporaneous with the Distribution, certain of the Separately Filing Group Members executed joinders to, and thereby became subject to the provisions of, the Global Hyatt Agreement.

The parties to the Global Hyatt Agreement agreed that until the later to occur of (i) January 1, 2015 and (ii) the date upon which more than 75% of the Issuer’s fully diluted shares of Common Stock is owned by persons other than Pritzker family members and spouses (including any U.S. Situs Trusts or non-U.S. situs trusts for the current or future, direct or indirect, vested or contingent, benefit of Pritzker family members and spouses) (the “Lock-Up Expiration Date”), all Pritzkers (as defined in the Global Hyatt Agreement) (and their successors in interest, if applicable), but not the transferees by sale (other than Pritzkers who purchase directly from other Pritzkers), will vote all of their voting securities consistent with the recommendations of the board of directors of the Issuer with respect to all matters (assuming agreement as to any such matter by a majority of a minimum of three independent directors (excluding for such purposes any Pritzker) or, in the case of transactions involving the Issuer and an affiliate, assuming agreement of all of such minimum of three independent directors (excluding for such purposes any Pritzker)). All Pritzkers have agreed to cast and submit by proxy to the Issuer their votes in a manner consistent with the foregoing voting agreement at least five business days prior to the scheduled date of the annual or special meeting of stockholders, as applicable.

In addition, the parties to the Global Hyatt Agreement agreed that until the Lock-Up Expiration Date, all Pritzker family members and spouses (including trusts for the current or future, direct or indirect, vested or contingent, benefit of any Pritzker family members and spouses or affiliates of any thereof) in a “beneficiary group” (as defined below) (including trusts only to the extent of the then current benefit of members of such beneficiary group) may sell up to 25% of their aggregate holdings of the Common Stock, measured as of November 4, 2009, in each 12-month period following November 4, 2009 (without carry-overs), and shall not sell more than such amount during any such period. Upon the unanimous affirmative vote of the independent directors of the Issuer (excluding for such purposes any Pritzker), such 25% limitation may, with respect to each such 12-month period, be increased to a higher percentage or waived entirely. In connection with the IPO, the independent directors of the Issuer unanimously waived such 25% limitation with respect to shares sold in the IPO and U.S. Situs Trusts for the benefit of each beneficiary group collectively sold 26.7% of the beneficiary groups’

aggregate holdings of the Common Stock in the IPO. No additional shares of Common Stock may be sold prior to November 5, 2010 without the further unanimous affirmative vote of the independent directors of the Issuer. Sales of the Common Stock between and among Pritzkers is permitted without regard to the sale restrictions described above and such sales are not counted against the 25% sale limitation. All shares of the Common Stock owned by each beneficiary group (including trusts only to the extent of the then current benefit of members of such beneficiary group) are freely pledgeable to an institutional lender and such institutional lender will not be subject to the sale restrictions described above upon default and foreclosure.

The Global Hyatt Agreement may be amended, modified, supplemented or restated by the written agreement of the co-trustees of the U.S. Situs Trusts, 75% of the adult beneficiaries named below and a majority of the other adult beneficiaries party to the agreement. Each of Thomas J. Pritzker, Nicholas J. Pritzker, James N. Pritzker, John A. Pritzker, Linda Pritzker, Karen L. Pritzker, Penny Pritzker, Daniel F. Pritzker, Anthony N. Pritzker, Gigi Pritzker Pucker and Jay Robert Pritzker, and their respective lineal descendants and current spouse, if relevant, make up a “beneficiary group.”

Disputes that relate to the subject matter of the Global Hyatt Agreement are subject to arbitration pursuant to the terms of the agreement. The exclusive requirement to arbitrate under the Global Hyatt Agreement does not apply with respect to the manner in which the Issuer’s operations are conducted to the extent the parties (in their capacities as stockholders) and non-Pritzker public stockholders are affected comparably; provided, however, that a party may participate in and benefit from any shareholder litigation initiated by a non-party to the agreement. A party to the agreement may not solicit others to initiate or be a named plaintiff in such litigation (i) unless two thirds of the independent directors (excluding for such purposes any Pritzker) on the board of directors of the Issuer (consisting of 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 the board of directors of the Issuer, unless at least one independent director (excluding for such purposes any Pritzker) did not approve the transaction.

The summary of the Global Hyatt Agreement contained in this Item 6 is qualified in its entirety by reference to the Global Hyatt Agreement, which is filed as Exhibit 2 hereto and incorporated herein by reference.

On October 26, 2009, the Reporting Persons, solely in their capacity as co-trustees of U.S. situs trusts for the benefit of Thomas J. Pritzker, Penny Pritzker and Gigi Pritzker Pucker and their lineal descendants, that own, directly or indirectly, shares of the Common Stock of the Issuer and Thomas J. Pritzker, Penny Pritzker and Gigi Pritzker Pucker and their respective adult lineal descendants entered into an Amended and Restated Agreement Relating to Stock (the “Agreement Relating to Stock”) whereby such parties have agreed to further restrict their ability to transfer certain shares of Common Stock. Contemporaneous with the Distribution, certain of the Separately Filing Group Members executed joinders to, and thereby became subject to the provisions of the Agreement Relating to Stock.

Subject to limited permitted transfers described in the Agreement Relating to Stock and subject to the terms of the Global Hyatt Agreement described above and that certain Amended and Restated Foreign Global Hyatt Agreement, dated as of October 1, 2009 (the “Foreign Global Hyatt Agreement”), entered into by certain of the Separately Filing Group Members, the parties have agreed that each stockholder party to the Agreement Relating to Stock may transfer up to one-third of its Common Stock held as of August 28, 2007 (or deemed to be held as of such date) to unaffiliated third parties during each 365-day period beginning on the dates that are three and one-half, four and one-half and five and one-half years following the consummation of the IPO; provided that such transfers are accomplished by way of a broad distribution sale.

In addition, each stockholder may transfer up to one-third of its Common Stock held as of August 28, 2007 (or deemed to be held as of such date) to unaffiliated third parties (1) at any time following the end of the first calendar year during which the “existing stockholders” (as described below) owned less than 25% of the Common Stock at any time during such year or (2) at any time following the first date on which the applicable market value of the Class A Common Stock exceeds $44.55 per share; provided that such transfers are accomplished by way of an underwritten public offering or in an otherwise broad distribution sale. The term “existing stockholders” is defined in the agreement to mean (i) members of the Pritzker family who are lineal descendants of Nicholas J. Pritzker, deceased, and their spouses, (ii) trusts for the benefit of such persons, or (iii) affiliates of any such persons listed in clauses (i) and (ii).

In addition, no stockholder party to the Agreement Relating to Stock may transfer (i) the legal or beneficial ownership of any shares of Common Stock held by such stockholder unless such acquiring person’s ownership of Common Stock is not reasonably likely to jeopardize any licensing from a governmental authority, (ii) any Common Stock to a competitor of the Issuer engaged in one or more of the hospitality, lodging or gaming industries, (iii) any Common Stock to an aggregator (i.e., a person who is required to file a Schedule 13D (or successor form) under the Act, disclosing an intent other than for investment) or (iv) any Common Stock that would cause a stockholder to violate any provision of the Agreement Relating to Stock. Such restrictions are qualified by the “actual knowledge” of the transferring stockholder in the case of transfers pursuant to an underwritten public offering or a broad distribution sale.

The transfer restrictions set forth in the Agreement Relating to Stock expire at 11:59 p.m. (Central time) on the earlier of the day after the date that is five and one-half years following November 10, 2009 (the closing of the IPO) or the date on which the stockholders party to that certain Global Hyatt Corporation 2007 Stockholders’ Agreement, dated as of August 28, 2007, by and among Hyatt Hotels Corporation (f/k/a Global Hyatt Corporation) and certain other parties, are released from the transfer restrictions set forth therein. The Agreement Relating to Stock may be amended by the holders of a majority of the restricted stock held by the stockholders party to the agreement and each of Thomas J. Pritzker, Penny Pritzker and Gigi Pritzker Pucker, and may be terminated by the written agreement of each of the parties thereto. Disputes that relate to the subject matter of the Agreement Relating to Stock are subject to arbitration.

The summary of the Agreement Relating to Stock contained in this Item 6 is qualified in its entirety by reference to the Agreement Relating to Stock, which is filed as Exhibit 3 hereto and incorporated herein by reference.

The Reporting Persons and the Separately Filing Group Members are party to, or entitled to rights under, a Registration Rights Agreement, dated as of October 12, 2009, among the Issuer and the domestic and foreign Pritzker stockholders party thereto (the “2009 Registration Rights Agreement”). Pursuant to the 2009 Registration Rights Agreement, the Issuer granted registration rights with respect to shares of Class A Common Stock issuable upon conversion of shares of Class B Common Stock to holders of 104,893,502 shares of the Class B Common Stock. Only shares of Class A Common Stock may be registered pursuant to the terms of the 2009 Registration Rights Agreement.

The Reporting Persons are entitled to certain demand registration rights under the 2009 Registration Rights Agreement. Specifically, the Reporting Persons and the Separately Filing Group Members may request that the Issuer register all or a portion of their shares of Class A Common Stock issuable upon conversion of shares of Class B Common Stock under the Securities Act of 1933 (the “Securities Act”) if the anticipated aggregate offering amount of such shares of Class A Common Stock exceeds a specified amount and the stockholders making the request are, at the anticipated time of effectiveness of the applicable registration statement, permitted to sell shares of their Common Stock under the applicable lock-up provisions contained in the Global Hyatt Agreement, Foreign Global Hyatt Agreement and the Agreement Related to Stock, and the Issuer is not otherwise prohibited from filing such registration statement under that certain Registration Rights Agreement, dated as of August 28, 2007, by and among the Issuer and certain other parties thereto (the “2007 Registration Rights Agreement”).

The Reporting Persons are entitled to certain Form S-3 demand registration rights under the 2009 Registration Rights Agreement. Commencing on the date that the Issuer becomes eligible to register securities issued on Form S-3, the Reporting Persons and the Separately Filing Group Members holding the requisite amount of Common Stock may request that the Issuer register all or a portion of their shares of Class A Common Stock issuable upon conversion of shares of Class B Common Stock under the Securities Act if the anticipated aggregate offering amount of such shares of Class A Common Stock exceeds a specified amount and the stockholders making the request are, at the

anticipated time of effectiveness of the applicable registration statement, permitted to sell shares of their Common Stock under the applicable lock-up provisions contained in the Global Hyatt Agreement, Foreign Global Hyatt Agreement and the Agreement Related to Stock, and the Issuer is not otherwise prohibited from filing such registration statement under the 2007 Registration Rights Agreement.

Under the 2009 Registration Rights Agreement, the Issuer is not required to effect a demand registration or a Form S-3 demand registration within 180 days after the effective date of a registration statement related to a previous demand or Form S-3 demand registration. In addition, once every twelve months, the Issuer may postpone for up to 120 days the filing or the effectiveness of a registration statement for a demand or a Form S-3 demand registration in certain circumstances described in the 2009 Registration Rights Agreement.

The Reporting Persons are entitled to certain “shelf” registration rights with respect to shares of Class A Common Stock issuable upon conversion of shares of Class B Common Stock under the 2009 Registration Rights Agreement.

The Reporting Persons are entitled to certain “piggyback” registration rights with respect to shares of Class A Common Stock issuable upon conversion of shares of Class B Common Stock under the 2009 Registration Rights Agreement.

The demand, Form S-3 demand and piggyback registration rights are subject to customary restrictions such as blackout periods and limitations on the number of shares to be included in the underwritten offering imposed by the managing underwriter.

The summary of the 2009 Registration Rights Agreement contained in this Item 6 is qualified in its entirety by reference to the 2009 Registration Rights Agreement, which is filed as Exhibit 4 hereto and incorporated herein by reference.

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.

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:

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.

Section 2.1 Representations and Warranties. Each of the parties signatory hereto hereby represents and warrants to each other party signatory hereto as follows:

(a) Such party has the full power, right and legal capacity to enter into this Agreement and to perform, observe and comply with all of such party’s agreements and obligations hereunder.

(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.

(d) Except as otherwise provided in or contemplated by this Agreement and except for any consent, approval, authorization, order, registration, qualification or notice required by gaming or other regulatory authorities, no consent, approval, authorization or order of, or registration or qualification with, or notice to any governmental authority or other Person is required by such party to enter into this Agreement.

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.

(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;

(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.

(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.

(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.

(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.

(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.

(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.

(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.

(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.

Each of the parties to this Agreement will be entitled to enforce its rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in its favor. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party shall be entitled to immediate injunctive relief or specific performance without bond or the necessity of showing actual monetary damages in order to enforce or prevent any violations of the provisions of this Agreement.

11. Counterparts; Effectiveness. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic image scan shall be effective as delivery of a manually executed counterpart of this Agreement.

12. No Trustee Liability. When this Agreement is executed by a trustee of a trust, such execution is by the trustee, not individually, but solely as trustee in the exercise of and under the power and authority conferred upon and invested in such trustee, and it is expressly understood and agreed that nothing contained in this Agreement shall be construed as imposing any liability on any such trustee personally to pay any amounts required to be paid hereunder or thereunder, or to perform any covenant, either express or implied, contained herein or therein, all such personal liability, if any, having been expressly waived by the parties by their execution hereof. Any liability of a trust hereunder shall not be a personal liability of any trustee, grantor or beneficiary thereof, and any recourse against a trustee shall be solely against the assets of the pertinent trust.

13. Entire Agreement. This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings (whether written or oral) between or among the Stockholders, or any of them, with respect to the subject matter hereof, including, the Original Agreement.

14. Amendment and Waiver. This Agreement may be amended, superseded, canceled, renewed or extended, and the terms hereof may be waived, only by a written instrument signed by (a) holders of a majority of the Restricted Stock held by the Stockholders at the time such action is proposed to be taken or, in the case of a waiver, by the parties waiving compliance, and (b) each of the then living and legally competent individuals listed on Schedule B attached hereto under the heading “B-1,” so long as each such individual is the legal or beneficial owner of Restricted Stock. No delay on the part of any party on exercising any right, power or privileges hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any party of any right, power or privilege, or any single or partial exercise of any such right, power or privilege, preclude any further exercise thereof or the exercise of any other such right, power or privilege.

15. Confidentiality and Public Announcements. No party hereto shall make any publicity releases, interviews or other disclosure or dissemination of any information concerning this Agreement or its terms, or any party’s performance hereunder, to any Person without the prior written approval of the other parties hereto; provided, however, that this provision shall not prevent disclosure: (a) as required by applicable law, (b) to any party’s financial advisors or legal advisors who are bound by similar terms of confidentiality, (c) as is, in good faith, deemed necessary or advisable under applicable securities laws or the rules and regulations of any stock exchange by which a party is bound or (d) in connection with enforcement of this Agreement in an arbitration proceeding pursuant to Section 6 hereof.

16. No Third Party Beneficiaries. Nothing in this Agreement is intended or shall be construed to give any Person, other than the parties hereto, their successors and permitted assigns, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

17. Waiver of Certain Damages. To the extent permitted by applicable law, each party hereto agrees not to assert, and hereby waives, any claim against any other party hereto, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any of the transactions contemplated hereby.

18. Joinder by Adult Beneficiaries. The Adult Beneficiaries are joining this Agreement as beneficiaries under certain of the trusts listed on Schedules A-1, A-2, and A-3, as applicable, to confirm to the Trustees that the Adult Beneficiaries believe this Agreement is in their and their descendants’ best interests and welfare, that on their own behalf and on behalf of their descendants they consent to this Agreement, that they desire the Trustees to enter into this Agreement and that in the event the Adult Beneficiaries receive distributions or other Transfers of any Restricted Stock after the Effective Date, such Restricted Stock shall remain subject to the terms of this Agreement. Each Adult Beneficiary agrees that at such time as any child of such Adult Beneficiary turns 18 years old (a “New AB”) prior to the Restriction Expiration Date, such Adult Beneficiary shall use reasonable best efforts to secure the joinder of such New AB to this Agreement. Upon the execution of such joinder by a New AB, such New AB will be considered to be an Adult Beneficiary for all purposes hereunder and Schedule B hereto shall be deemed to be updated to reflect the addition of such New AB.

19. Termination. This Agreement shall terminate and be of no further force and effect on the first to occur of (a) with respect to any Stockholder, on the first date when such Stockholder no longer holds any shares of Restricted Stock, (b) upon the agreement in writing of each of the Stockholders party hereto or (c) on the Restriction Expiration Date; provided, that Sections 4 through 19 shall survive any termination or expiration of this Agreement.

IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement Relating to Stock as of the date first above written.
