Item 1.01. Entry into a Material Definitive Agreement.

(a) Creation of a Revolving Credit Facility

On March 31, 2009, Caterpillar Inc. entered into a Credit Agreement (the "364-Day Facility") among Caterpillar Inc. and Caterpillar Financial Services Corporation ("Borrowers"), certain financial institutions named therein ("Banks") and Citibank, N.A. ("Administrative Agent") that provides for an unsecured aggregate revolving credit facility to the Borrowers of approximately US$1.375 billion ("Aggregate Commitment") and expires on March 30, 2010.

The 364-Day Facility serves as an alternative source of funds for general corporate purposes, if necessary, for the Borrowers. The Borrowers have not drawn on the 364-Day Facility.

The 364-Day Facility contains customary representations and warranties, covenants and events of default that may allow the Banks to, among other things,
(i) terminate the commitments made under the 364-Day Facility, or (ii) to the extent advances are made under the 364-Day Facility, accelerate the payment obligations thereunder. The 364-Day Facility is subject to customary conditions precedent and payment of certain facility fees in quarterly arrears. Borrowings under the 364-Day Facility bear interest at an adjusted applicable rate based on specified types of advances (i.e., US Dollar or Euro advances), plus a certain applicable margin.

Some of the Banks, as well as certain of their respective affiliates, have performed, and may in the future perform, for the Borrowers, various commercial banking, investment banking, underwriting and other financial advisory services, for which they have received, and will receive, customary fees and expenses.

The foregoing description of the 364-Day Facility is a summary and is qualified in its entirety by the terms and provisions of the 364-Day Facility and the Notice of Bank Addition and the Assumption and Acceptance, both dated April 7, 2009, adding The Bank of Tokyo-Mitsubishi UFJ, Ltd. as a party to the 364-Day Credit Facility for a US$75 million commitment, filed, respectively as Exhibits 99.1 and 99.2 to this report, and incorporated herein by reference.
