Terms of the 2006 Stock Appreciation Rights Awards

The following terms apply to the Global Hyatt Corporation Stock Appreciation Rights granted on October 6, 2006.

Exercise of the SARs entitles the participant to receive an amount equal to the “Spread,” if any, determined at the time of exercise. The Spread is the difference (but not less than zero) between the Share Value (as defined below) of a share of Global Hyatt Corporation common stock at the time of exercise and the SAR’s Base Value (which is the Share Value at the grant date) multiplied by the number of SARs exercised. Reference to a “share” or “shares” is to Global Hyatt Corporation common stock.

SARs will vest on such dates only if the Participant remains in continuous Service with the Company from the date of grant through such vesting date.

Except as provided below, all unvested SARs will be forfeited upon termination of Service and all vested SARs will remain outstanding, provided that such vested SARs shall be automatically exercised during the Exercise Window (as defined below) which immediately follows termination of Service.

Vesting of the SARs will accelerate in the following circumstances:

Terms of 2006 SARs – Page 1

As described below, vested and unvested SARs are subject to cancellation and forfeiture in the event a Participant engages in certain “detrimental conduct” (as defined below).

The “Exercise Window” is a period which will commence on the date the Share Value (as defined below) is communicated to Participants and end on the date set forth by the Administrator, which date shall be not less than 30 days thereafter. It is anticipated that the Exercise Window will begin in March of each year, commencing in 2007.

If after being informed of the Share Value a Participant elects to exercise some or all of his or her vested SARs, such Participant may do so by filing an exercise form during the Exercise Window in accordance with procedures established by the Administrator and communicated to Participants.

Settlement of exercised SARs will occur as promptly as practicable following the end of the Exercise Window. Settlement will be accomplished through the issuance of shares to the Participant having a value (based on the Share Value determined at the time of exercise) equal to the aggregate amount of the Spread, if any, applicable to the exercised SARs. The Administrator may direct that the settlement shall be made in cash. The issuance of shares or payment of cash will be subject to tax withholding, as provided below.

Each year, commencing in 2007, the Company will advise the Participants of the new Share Value, upon which the Exercise Window will open as described above.

Terms of 2006 SARs – Page 2

Without limiting any of the rights of the Company or the Administrator hereunder or under the Plan, upon receipt of shares, each Participant shall be deemed to have agreed that upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, the Participant will (a) not sell, make any short sale of, loan, grant any option for the purchase of, otherwise dispose of, hedge or transfer any of the economic interest in (or agree or commit to do any of the foregoing) any shares received upon exercise of SARs or any other securities of Global Hyatt Corporation (other than those included in the registration, if any) held by the Participant without the prior written consent of the Company or such underwriters, as the case may be, for up to fourteen (14) days prior to, and, in the case of the Company’s initial public offering of equity securities, during the one hundred eighty (180) day period (or such longer period as may be required by the Administrator upon the advice of the managing underwriter(s)) following, the effective date of a registration statement of the Company filed under the Securities Act of 1933, as amended, and (b) enter into and be bound by such form of agreement with respect to the foregoing as the Company or such managing underwriter may reasonably request. In the case of a registered public offering of the Company’s equity securities following the Company’s initial public offering, the lock-up period described in clause (a) above shall be ninety (90) days (or such longer period as may be required by the Administrator).

Terms of 2006 SARs – Page 3

In addition, following the termination of a Participant’s Service, the Company shall have the right to call any such shares in full or in part during an Exercise Window on the terms set forth in the Stockholder’s Agreement.

Payment for any shares sold by the Participant or called by the Company shall be made as promptly as practicable after the end of the Exercise Window on the terms set forth in the Stockholders’ Agreement.

No income is recognized upon the grant or vesting of the SAR. Upon exercise, the shares are delivered and ordinary income is recognized in an amount equal to the Spread received. Unless paid in cash by the Participant at the time of settlement, the Company will deduct or withhold from shares issuable upon exercise a number of shares having a value (based on the then applicable Share Value) equal to the amount sufficient to satisfy the minimum statutory Federal, state and local tax (including the FICA and Medicare tax obligation) withholding required by law with respect to the exercise. Any cash payment in settlement of an SAR exercise will be reduced by applicable tax withholding. Because such withholding is at the minimum statutory rate, a Participant’s actual tax liability with respect to the exercise of SARs is likely to exceed the amount withheld.

A subsequent sale (including pursuant to a put or call described above) or exchange of shares will result in gain or loss measured by the difference between (a) the Share Value at the time the shares were received, and (b) the amount realized on such sale or exchange. Any gain or loss will be a capital gain or loss and will be long-term if such shares were held for more than one year.

Each Participant is encouraged to consult with a tax advisor regarding the tax consequences of participation in the Plan.

Capitalized terms not defined herein shall have the meaning ascribed to them in the Plan.

Effect of Detrimental Conduct. In the event a Participant engages in “detrimental conduct” (as defined below), the Participant shall forfeit all unvested and/or vested but unexercised awards under the Plan and all such awards shall be null and void as of the date such detrimental conduct first occurs.

Determination of Detrimental Conduct. Upon a reasonable, good faith determination that detrimental conduct has occurred, the Administrator shall give the Participant written notice, which shall specify the conduct and the date of the conduct. Any dispute concerning the matters set forth in the notice shall be decided under the procedures in the Plan.
