Item 1.01. Entry into a Material Definitive Agreement.

On September 30, 2011, certain subsidiaries of Snap-on Incorporated (“Snap-on”) amended their loan and servicing agreement with a group of conduit lenders, committed lenders, administrative agents and JPMorgan Chase Bank, N.A., as program agent, to, among other things: (1) increase the aggregate revolving credit commitments under the agreement from a principal amount of up to $100 million to a principal amount of up to $200 million (subject to borrowing base requirements); (2) extend the expiration date of the agreement from September 30, 2011 to September 28, 2012 (unless earlier terminated or subsequently extended pursuant to the terms of the agreement); (3) provide that any amounts remaining outstanding under the agreement as of September 30, 2014, or such earlier date as may be prescribed pursuant to the terms of the agreement, will become due and payable on such date; and (4) change certain pricing terms. The Snap-on subsidiaries effected these amendments by entering into an omnibus amendment, dated September 30, 2011 (the “Omnibus Amendment”), with the parties to the loan and servicing agreement and the related receivables sale agreement.

Except as modified by the Omnibus Amendment and a previous non-material amendment, copies of the original loan and servicing agreement and receivables sale agreement, as well as descriptions of their material provisions, were included in Snap-on’s Current Report on Form 8-K, dated October 1, 2010.
