On July 10, 2013, Woodward, Inc. (the “Registrant”) entered into a Credit Agreement (the “New Revolver Agreement”), by and among the Registrant, certain foreign subsidiary borrowers of the Registrant from time to time parties thereto, the institutions from time to time parties thereto, as lenders, Wells Fargo Bank, National Association, as administrative agent, JPMorgan Chase Bank, N.A., and The Bank of Tokyo-Mitsubishi UFJ, Ltd., as co-syndication agents, U.S. Bank National Association, as documentation agent, and Wells Fargo Securities, LLC, JPMorgan Securities, LLC, and The Bank of Tokyo-Mitsubishi UFJ, Ltd., as joint lead arrangers and book runners. The New Revolver Agreement replaces the 2012 Revolver Agreement (as defined under Item 1.02 below) and matures on July 10, 2018.

As compared to the 2012 Revolver Agreement, the New Revolver Agreement increases the initial commitment from $400,000,000 to $600,000,000 and maintains the option to expand the commitment by $200,000,000, for a total of up to $800,000,000. The New Revolver Agreement generally bears interest at LIBOR (or, for loans denominated in Canadian dollars, CDOR) plus 0.85% to 1.65%, which is due quarterly in arrears on any outstanding borrowings. Proceeds from the New Revolver Agreement may be used for general corporate purposes and the ongoing working capital needs of the Registrant and its subsidiaries, including acquisition financing, capital expenditures and the refinancing of the 2012 Revolver Agreement and other existing indebtedness.

The New Revolver Agreement contains representations and warranties, affirmative and negative covenants, including financial covenants regarding maximum leverage ratio and minimum consolidated net worth, and events of default that are customary and generally consistent with the terms of the 2012 Revolver Agreement, subject to various changes to the affirmative and negative covenants consistent with the increase in the commitment described above, and additional covenant relief from the covenants contained in the 2012 Revolver Agreement. These changes include, with respect to the financial covenants, (i) subject to certain additional restrictions contained in the New Revolver Agreement, increasing the maximum permitted leverage ratio of the Registrant and its consolidated subsidiaries from 3.50:1.00 to 4.00:1.00 for the fiscal quarter (and the immediately following fiscal quarter) during which a permitted acquisition occurs and to 3.75:1.00 for the next two succeeding fiscal quarters, and (ii) increasing the minimum required consolidated net worth of the Registrant from a base of $725,000,000 to a base of $800,000,000, plus 50% of the Registrant’s positive net income for the prior fiscal year and plus 50% of the Registrant’s net cash proceeds resulting from certain issuances of stock, subject to certain adjustments. The New Revolver Agreement also includes customary conditions precedent to the making of advances and the issuance of letters of credit.

Upon the occurrence of a Default (as defined in the New Revolver Agreement), all amounts outstanding under the New Revolver Agreement, including principal, accrued interest, and any other fees may, and in the case of certain bankruptcy-related Defaults will, be accelerated and become immediately due and payable.

The Registrant’s obligations under the New Revolver Agreement are guaranteed by Woodward FST, Inc., Woodward MPC, Inc. and Woodward HRT, Inc., each of which is a wholly owned subsidiary of the Registrant.

The Registrant has other relationships, including financial advisory and banking, with some parties to the New Revolver Agreement.

The foregoing description of the New Revolver Agreement and related matters is qualified in its entirety by reference to the New Revolver Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

A copy of the press release announcing the Registrant’s entry into the New Revolver Agreement is filed as Exhibit 99.1 hereto.

Morgan Securities LLC, Wells Fargo Securities, LLC and The Bank of Tokyo-Mitsubishi UFJ, Ltd., as joint lead arrangers and book runners. The 2012 Revolver Agreement was to expire January 2017.
