On March 24, 2015, Rockwell Automation, Inc. (the “Company”) entered into a $1,000,000,000 five-year unsecured revolving credit agreement with the Banks listed therein, JPMorgan Chase Bank, N.A., as Administrative Agent, Bank of America, N.A. and Goldman Sachs Bank USA, as Syndication Agents, and The Bank of New York Mellon, BMO Harris Bank N.A., Citibank, N.A., Deutsche Bank Securities Inc., The Northern Trust Company, PNC Bank, National Association, U.S. Bank National Association and Wells Fargo Bank, National Association, as Documentation Agents (the “Agreement”). The Company has the option to increase the aggregate amount of the commitments under the Agreement by up to $350,000,000, subject to certain conditions set forth in the Agreement. The Agreement replaces the $750,000,000 Five-Year Credit Agreement dated May 22, 2013 among the Company, the Banks listed therein, JPMorgan Chase Bank, N.A., as Administrative Agent, Bank of America, N.A., as Syndication Agent, and The Bank of New York Mellon, BMO Harris Bank N.A., Citibank, N.A., Deutsche Bank Securities Inc., The Northern Trust Company, PNC Bank, National Association, U.S. Bank National Association and Wells Fargo Bank, National Association, as Documentation Agents, which terminated early concurrently with the Company entering into the Agreement (the “Old Agreement”). The Company did not incur any early termination penalties in connection with the termination of the Old Agreement.

The proceeds of borrowings under the Agreement will be used for general corporate purposes.

Borrowings under the Agreement will bear interest at variable rates equal to, at the Company’s election (1) for each base rate loan, the sum of the base rate plus the base rate margin, and (2) for each euro-dollar loan, the sum of the euro-dollar margin plus the London Interbank Offered Rate for deposits in dollars with a maturity comparable to the interest period selected by the Company. The base rate equals the highest of (a) the prime rate, (b) the sum of the federal funds rate plus  ¹⁄₂ of 1% and (c) the sum of 1% plus the London Interbank Offered Rate for a one-month interest period. The base rate margin is the excess, if any, of the euro-dollar margin over 1.00%. The euro-dollar margin for a given credit rating level is a percentage from 0.75% to 1.50% as specified for that credit rating level. The Company elects the basis of the interest rate (base rate or euro-dollar) at the time of each borrowing and may elect to change the interest rate basis from time to time.

The Agreement contains, among other things, conditions precedent, covenants, representations and warranties and events of default customary for facilities of this type. The conditions precedent, covenants, representations and warranties and events of default set forth in the Agreement and the Old Agreement are substantially the same. Such covenants restrict certain incurrence of secured indebtedness, mergers, consolidations and sales of assets and sale and lease-back transactions, subject to certain exceptions. The Agreement also includes a covenant under which the Company would be in default if its debt to capital ratio were to exceed 60 percent.

Under certain conditions the lending commitments under the Agreement may be terminated by the lenders and amounts outstanding under the Agreement may be accelerated. Bankruptcy and insolvency events with respect to the Company will result in an automatic termination of lending commitments and acceleration of the indebtedness under the Agreement. Subject to notice and cure periods in certain cases, other events of default under the Agreement will result in termination of lending commitments and acceleration of indebtedness under the Agreement at the option of the lenders. Such other events of default include failure to pay any principal when due, failure to comply with covenants, breach of representations or warranties in any material respect, non-payment or acceleration of other material debt of the Company and its subsidiaries or a change of control of the Company.

The foregoing summary of the Agreement does not purport to be a complete description of the terms and conditions of the Agreement and is qualified by the full text of the Agreement attached as Exhibit 99, which is incorporated herein by reference. The Agreement has been attached to provide investors with more complete information regarding the terms and conditions of the Agreement, and it is not intended to be a source of factual, business or operational information about the Company.

From time to time, the Company and the lenders under the Agreement (or affiliates of the lenders) may engage in other transactions, including arrangements under which a lender or an affiliate of the lender participates in interest rate swap or hedging arrangements with the Company, effects repurchases of shares of the Company’s common stock, serves as agent or placement agent for or purchaser of commercial paper or underwriter or purchaser of other debt issued by the Company, provides cash management, financial advisory, corporate trust, investment banking or commercial banking services to the Company, provides lines of credit to the Company or its affiliates or manages the Company’s pension fund assets. The Bank of New York Trust Company, N.A. (successor in interest to JPMorgan Chase Bank, N.A., successor to JPMorgan Chase Bank, successor to The Chase Manhattan Bank, successor to Mellon Bank, N.A.), a subsidiary of The Bank of New York Mellon, a lender and Documentation Agent under the Agreement (and the Old Agreement), is trustee under the Indenture dated as of December 1, 1996, between the Company and The Bank of New York Trust Company, N.A., as trustee, pursuant to which the Company has issued certain long-term indebtedness.
