Item 1.01. Entry into a Material Definitive Agreement.

On August 2, 2007, Wyeth entered into a $3.0 billion, five-year revolving credit facility with a group of banks and other financial institutions named therein and with JPMorgan Chase Bank, N.A. acting as Administrative Agent. The new credit facility replaces Wyeth’s prior $1,350.0 million, five-year credit facility maturing in August 2010 and its prior $1,747.5 million, five-year credit facility maturing in February 2009, which were terminated concurrent with the effectiveness of the new credit facility. Wyeth had not drawn any funds from either of the prior facilities that were terminated nor has it drawn any funds under the new facility.

The new credit facility matures in August 2012 and is extendable by one year on each of the first and second anniversary dates with the consent of the lenders. Borrowings under the new credit facility may be used for general corporate and working capital purposes and to support commercial paper, if any. The agreement governing the new facility contains customary terms and conditions substantially similar to the prior facilities, including a requirement to maintain a ratio of consolidated adjusted indebtedness to adjusted capitalization not in excess of 60%.

Wyeth has other arms-length relationships with certain of the participating banks and financial institutions. In addition, Raymond J. McGuire, a Director of Wyeth, is a Managing Director and Co-Head, Global Investment Banking for Citigroup Global Markets Inc., a subsidiary of Citigroup Inc. (“Citigroup”), one of the Co-lead Arrangers and Joint Bookrunners of the facility. Affiliates of Citigroup are also acting as Syndication Agent and as a lender under the facility.

The foregoing summary is subject to, and qualified in its entirety by reference to, all the provisions of the definitive agreement establishing the new facility, which is filed as Exhibit 10.1 hereto.
