Dealer Agreements

On October 2, 2012, Wyndham Worldwide Corporation (the “Company”) entered into a new commercial paper program (the “Program”) on a private placement basis under which the Company may issue from time to time unsecured commercial paper notes (the “Notes”) up to a maximum aggregate amount outstanding at any time of up to $500,000,000. The proceeds of the issuance of the Notes will be used for general corporate purposes. Amounts available under the Program may be reborrowed. The Company’s revolving credit agreement is available to repay the Notes, if necessary.

The Program serves as an alternative source of funding but not as an increase to the Company’s overall debt. Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities LLC, Deutsche Bank Securities Inc., RBS Securities Inc. and SunTrust Robinson Humphrey, Inc. each will act as a dealer under the Program (collectively the “Dealers”) pursuant to the terms and conditions of their respective Dealer Agreements (each, a “Dealer Agreement”). U.S. Bank National Association will act as Issuing and Paying Agent under the Program.

The Program provides the terms under which the Dealers will either purchase from the Company or arrange for the sale by the Company of Notes pursuant to an exemption from federal and state securities laws. The Program contains customary representations, warranties, covenants and indemnification provisions. The maturities of the Notes will vary but may not exceed 366 days from the date of issue. The principal amount of outstanding Notes under the Program may not exceed $500,000,000. The Notes will be sold at a negotiated discount from par or will bear interest at a negotiated rate.

A Form of Dealer Agreement is attached to this report as Exhibit 10.1 and is incorporated herein by reference as though it were fully set forth herein. The description above is a summary of the Program and is qualified in its entirety by the complete text of the Program itself as set forth in the Dealer Agreements.

The information related to the $500,000,000 unsecured commercial paper program described under Item 1.01 above is hereby incorporated by reference under this Item 2.03.
