On June 30, 2011, Diebold, Incorporated (the “Company”), along with one of its foreign subsidiaries, entered into a Credit Agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent and a lender, and the other lenders party thereto. The Credit Agreement provides for a revolving credit facility in a maximum aggregate principal amount outstanding at any one time of $500.0 million (and/or the equivalent thereof in other permitted currencies). The Credit Agreement contains an accordion feature allowing the maximum aggregate principal amount of the revolving facility to be increased by up to, and/or new facilities to be established thereunder in, from time to time, an additional aggregate amount of $250.0 million (and/or the equivalent thereof in other permitted currencies). Up to $50.0 million of the revolving credit facility is available under a swingline subfacilty.

The revolving credit facility provided for under the Credit Agreement replaces the Company’s revolving credit facilities under that certain Loan Agreement (the “Prior Loan Agreement”), dated as of October 19, 2009, among the Company, one of its foreign subsidiaries, JPMorgan Chase Bank, N.A., as agent and a lender, and the other lenders party thereto. The Company used borrowings of approximately $322 million under the Credit Agreement to repay all amounts owing under (and terminated) the Prior Loan Agreement. The maturity date of the Prior Loan Agreement had been October 19, 2012.

The revolving credit facility provided for under the Credit Agreement matures on June 30, 2016, and is unsecured.

Loans under the revolving credit facility will bear interest at, at the applicable borrower’s election, either (a) LIBOR plus a percentage spread (ranging from 0.975% to 1.575%) based on the Company’s total net debt to capitalization ratio or (b) the alternate base rate, described in the Credit Agreement as the greatest of (i) JPMorgan Chase’s prime rate, (ii) the federal funds rate plus 0.50% and (iii) one-month LIBOR plus 1.00%, plus a percentage spread (ranging from 0.00% to 0.575%) based on the Company’s total net debt to capitalization ratio. Swing loans under the swingline subfacility will bear interest at such rates as the applicable borrower and the swingline lender may agree.

The Company has agreed to pay a facility fee, payable quarterly, at rates that range from 0.15% to 0.30% (based on the Company’s total net debt to capitalization ratio), and customary administrative agent fees and fees in respect of letters of credit.

The Credit Agreement contains customary affirmative and negative covenants for credit facilities of this type, including limitations on the Company’s subsidiaries with respect to indebtedness and limitations on the Company and its subsidiaries with respect to liens, nature of business, investments and loans, acquisitions, dispositions of assets and transactions with affiliates. The Credit Agreement also contains financial covenants that require the Company to maintain, on a consolidated basis, a total net debt to capitalization ratio of less than or equal to 50% and an interest coverage ratio of greater than or equal to 5.00 to 1.00.

The Credit Agreement contains customary events of default with corresponding grace periods. If an event of default occurs and is continuing, the lenders may terminate and/or suspend their obligations to make loans and issue letters of credit under the Credit Agreement and/or accelerate amounts due under the Credit Agreement and exercise other rights and remedies. In the case of certain events of default related to insolvency and receivership, the commitments of the lenders will be automatically terminated and all outstanding obligations of the Company and the Subsidiary Borrowers (as defined in the Credit Agreement) will become immediately due and payable.

A copy of the Credit Agreement is filed as Exhibit 10.1 hereto. The foregoing description of the Credit Agreement does not purport to be complete, and is qualified in its entirety by reference to the full text of the Credit Agreement, which is incorporated by reference herein.

The disclosure set forth above under Item 1.01 is hereby incorporated by reference into this Item 1.02.
