On March 15, 2012, Wyndham Worldwide Corporation (“Wyndham Worldwide”) issued $150 million aggregate principal amount of 4.250% Notes due 2022 (the “Notes”) pursuant to its effective shelf registration statement on Form S-3 (File No. 333-179710), as filed with the Securities and Exchange Commission (the “SEC”) on February 27, 2012 (the “Registration Statement”). The terms of the Notes are governed by an indenture, dated November 20, 2008 between Wyndham Worldwide and U.S. Bank National Association, as trustee (the “Base Indenture”), as supplemented and amended by the sixth supplemental indenture thereto, dated March 7, 2012 (the “Sixth Supplemental Indenture”) and the seventh supplemental indenture thereto, dated March 15, 2012 (the “Seventh Supplemental Indenture” and, together with the Sixth Supplemental Indenture and the Base Indenture, the “Indenture”).

The Notes will constitute a further issuance of and are fungible with the $500 million aggregate principal amount of 4.250% Notes due 2022 issued by the Company on March 7, 2012

The Notes bear interest at a rate of 4.250% per year payable semi-annually in arrears on March 1 and September 1 of each year, commencing September 1, 2012.

The Notes are redeemable at any time prior to December 1, 2021 (three months prior to the maturity date of the Notes) at a redemption price equal to the sum of the principal being redeemed, plus a “make-whole” premium specified in the Notes and accrued and unpaid interest on the principal amount being redeemed to, but not including, the redemption date.

The Notes are redeemable on or after December 1, 2021 (three months prior to the maturity date of the Notes) at a redemption price equal to 100% of the principal amount of the notes being redeemed, plus accrued and unpaid interest on the principal amount being redeemed to, but not including, the redemption date.

If Wyndham Worldwide experiences a Change of Control Triggering Event (as defined in the Indenture), Wyndham Worldwide is required to offer to repurchase the Notes at 101% of their principal amount plus accrued and unpaid interest, if any, to the date of purchase.

The Indenture contains customary provisions for events of default including for failure to pay principal or interest when due and payable, failure to comply with covenants or agreements in the Indenture or the Notes and failure to cure or obtain a waiver of such default upon notice, a default under other debt of Wyndham Worldwide or certain of its subsidiaries such that at least $50 million aggregate principal amount of indebtedness is accelerated which acceleration has not been rescinded or annulled within 30 days of notice, and events of bankruptcy, insolvency or reorganization affecting Wyndham Worldwide and certain of its subsidiaries. In the case of an event of default, the principal amount of the Notes plus accrued and unpaid interest may be accelerated. The Indenture also contains covenants limiting the ability of Wyndham Worldwide to incur debt secured by liens and to enter into sale and lease back transactions.

The information provided in Item 1.01 with respect to Wyndham Worldwide’s issuance of the Notes is incorporated by reference herein.

On March 12, 2012, Wyndham Worldwide entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the several underwriters named therein, with respect to the issuance and sale of the Notes.
