Item 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On February 1, 2012, Brady Corporation (the “Corporation”) and certain of its subsidiaries entered into an unsecured $300 million revolving credit agreement with a group of six banks that replaced and terminated the Corporation’s previous $200 million revolving credit agreement that had been entered into on October 5, 2006 and amended on March 18, 2008. No fees were paid by the Corporation for terminating the previous credit agreement prior to its expiration date.

Under the new credit agreement, which has a final maturity date of February 1, 2017, the Corporation has the option to select either a base interest rate (based upon the higher of the federal funds rate plus one-half of 1% or the prime rate of Bank of America plus a margin based on the Company’s consolidated leverage ratio) or a Eurocurrency interest rate (at the LIBOR rate plus a margin based on the Company’s consolidated leverage ratio). The new credit agreement is guaranteed by the Corporation’s domestic subsidiaries and contains various financial covenants, including a debt-to-EBITDA ratio of 3.25-to-1.0 and an interest coverage ratio of 3.0-to-1.0. A commitment fee is payable on the unused amount of the credit facility. The Corporation intends to use the flexibility provided by the new credit agreement to refinance existing debt, to fund future acquisitions, and for general corporate purposes.

The foregoing description of the new credit agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the agreement, a copy of which is filed as Exhibit 10.1 to this report and is incorporated herein by reference.
