Item 1.01 Entry into a Material Definitive Agreement.

On November 30, 2012, Starwood Hotels & Resorts Worldwide, Inc. (the “Company”), certain of its subsidiaries, as borrowers, the lenders from time to time party thereto, JPMorgan Chase Bank, N.A., as administrative agent, Citigroup Global Markets Inc., as syndication agent, Bank of America, N.A., HSBC Bank USA, National Association and Wells Fargo Bank, National Association, as documentation agents, entered into a Credit Agreement (the “Credit Agreement”). The Credit Agreement is a $1.75 billion revolving credit facility, which refinanced the existing $1.50 billion Credit Agreement dated April 20, 2010, as amended (the “2010 Credit Facility”), that would have matured in November 2013. The Credit Agreement provides for revolving loans and the issuance of letters of credit to the Company and certain of its subsidiaries, with up to $500 million available in primary alternate currency sub-commitments consisting of U.S. dollars, Canadian dollars, Euros, Pounds Sterling, Australian dollars or Yen, $50 million for Mexican pesos, $100 million of other permitted Libor based currencies other than U.S. dollars and $100 million of other permitted non-Libor based currencies other than U.S. dollars, with an overall limit on outstanding loans in currencies other than U.S. dollars of $500 million.

The Company has also issued a loan guaranty. The Borrowers may prepay the outstanding aggregate principal amount, in whole or in part, at any time, subject to certain restrictions. The Credit Agreement also includes customary mandatory prepayment provisions which are triggered when certain events occur, for example, the Company inadvertently exceeding the sub-commitment limits for any currency for a period of five consecutive business days. The Credit Agreement and related documents contain customary affirmative, negative, and financial covenants and default provisions.

This new Credit Agreement replaces the 2010 Credit Facility which has now been terminated.

A copy of the Credit Agreement is attached as Exhibit 10.1 hereto and incorporated herein by reference. The foregoing description of the Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Agreement.

Item 1.02. Termination of a Material Definitive Agreement.

On November 30, 2012, in conjunction with the entrance into the Credit Agreement, the 2010 Credit Facility, dated April 20, 2010, among the Company, certain additional dollar revolving loan borrowers, certain additional alternate currency revolving loan borrowers, various lenders, Deutsche Bank AG New York Branch, as administrative agent, JPMorgan Chase Bank, N.A., as syndication agent, and Deutsche Bank Securities Inc., J.P. Morgan Securities Inc. and Banc of America Securities LLC, as lead arrangers and book running managers, was terminated. The 2010 Credit Facility was a $1.5 billion revolving credit facility that was prepayable subject to standard breakage provisions, if any, and was scheduled to mature in November 2013.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information contained in Item 1.01 concerning the Company’s direct financial obligations is hereby incorporated herein by reference.
