Credit Facilities

JPMorgan Chase Bank, National Association

On April 25, 2013, we entered into Amendment No. 1 to our 2011 Credit Agreement which amends the Credit Agreement, dated as of May 5, 2011, with JPMorgan Chase Bank, N. A. (“JPMorgan”), as administrative agent and collateral agent, U.S. Bank National Association, as syndication agent, Wells Fargo Bank, National Association, and RBS Citizens, N.A., as co-documentation agents, and the Lenders (including JPMorgan) from time to time party thereto (the “2011 Credit Agreement”). Under the original terms, the 2011 Credit Agreement provides us and certain of our foreign subsidiaries access to a senior unsecured credit facility until May 5, 2016, in the amount of $125,000, with an option to expand by up to $62,500 to a total of $187,500. Borrowings may be denominated in U.S. Dollars or certain other currencies. The 2011 Credit Agreement contains a $100,000 sublimit on borrowings by foreign subsidiaries.

Under the original terms of the 2011 Credit Agreement, the fee for committed funds ranges from an annual rate of 0.25% to 0.40%, depending on our leverage ratio. Eurocurrency borrowings under the 2011 Credit Agreement bear interest at a rate per annum equal to adjusted LIBOR plus an additional spread of 1.50% to 2.10%, depending on our leverage ratio. Alternate Base Rate (“ABR”) borrowings bear interest at a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.50% to 1.10%, depending on our leverage ratio.

Effective April 25, 2013, Amendment No. 1 to the 2011 Credit Agreement principally provides the following changes to the 2011 Credit Agreement:


•	extends the maturity date of the 2011 Credit Agreement to March 1, 2018;


•	changes the fees for committed funds under the 2011 Credit Agreement to an annual rate ranging from 0.20% to 0.35%, depending on our leverage ratio;


•	changes the per annum interest rate on Eurocurrency borrowings to adjusted LIBOR plus an additional spread of 1.30% to 1.90%, depending on our leverage ratio;


•	changes the ABR rate at which borrowings bear interest to a rate per annum equal to the greatest of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) the adjusted LIBOR rate for a one month period plus 1.0%, plus, in any such case, an additional spread of 0.30% to 0.90%, depending on our leverage ratio; and


•	changes related to new or recently revised financial regulations.

The 2011 Credit Agreement gives the Lenders a pledge of 65% of the stock of certain first tier foreign subsidiaries. The obligations under the 2011 Credit Agreement are also guaranteed by certain of our first tier domestic subsidiaries.

The 2011 Credit Agreement contains customary representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and merge or consolidate with another entity. Further, the 2011 Credit Agreement contains the following covenants:


•	a covenant requiring us to maintain an indebtedness to EBITDA ratio as of the end of each quarter of not greater than 3.00 to 1;


•	a covenant requiring us to maintain an EBITDA to interest expense ratio as of the end of each quarter of no less than 3.50 to 1;


•	a covenant restricting us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50,000 to $75,000 during any fiscal year based on our leverage ratio after giving effect to such payments; and


•	a covenant restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25,000.

As of December 31, 2013 we were in compliance with all covenants under the Credit Agreement. There was $10,000 in outstanding borrowings under this facility at December 31, 2013, with a weighted average interest rate of 1.47%.

Prudential Investment Management, Inc.

On July 29, 2009, we entered into a Private Shelf Agreement (the “Shelf Agreement”) with Prudential Investment Management, Inc. (“Prudential”) and Prudential affiliates from time to time party thereto. The Shelf Agreement provides us and our subsidiaries access to an uncommitted, senior secured, maximum aggregate principal amount of $80,000 of debt capital. The Shelf Agreement contains representations, warranties and covenants, including but not limited to covenants restricting our ability to incur indebtedness and liens and to merge or consolidate with another entity. The Shelf Agreement limits the payment of dividends or repurchases of stock to an amount ranging from $12,000 to $40,000 based on our leverage ratio after giving effect to such payments.

On May 5, 2011, we entered into Amendment No. 1 to our Private Shelf Agreement (the “Amendment”).

The Amendment principally provides the following changes to the Shelf Agreement:


•	elimination of the security interest in our personal property and subsidiaries;


•	an amendment to the maximum leverage ratio to not greater than 3.00 to 1 for any period ending on or after March 31, 2011;

•

an amendment to our restriction regarding the payment of dividends or repurchase of stock to restrict us from paying dividends or repurchasing stock if, after giving effect to such payments, our leverage ratio is greater than 2.00 to 1, in such case limiting such payments to an amount ranging from $50,000 to $75,000 during any fiscal year based on our leverage ratio after giving effect to such payments; and


•	an amendment to Permitted Acquisitions restricting our ability to make acquisitions, if, after giving pro-forma effect to such acquisition, our leverage ratio is greater than 2.75 to 1, in such case limiting acquisitions to $25,000.

On July 24, 2012, we entered into Amendment No. 2 to our Private Shelf Agreement (“Amendment No. 2”), which amends the Shelf Agreement. The principal change effected by Amendment No. 2 is an extension of the Issuance Period for Shelf Notes under the Shelf Agreement. The Issuance Period now expires on July 24, 2015.

As of December 31, 2013, there was $20,000 in outstanding borrowings under this facility; the $10,000 Series A notes issued in March 2011 with a fixed interest rate of 4.00% and a 7 year term serially maturing from 2014 to 2018; and the $10,000 Series B notes issued in June 2011 with a fixed interest rate of 4.10% and a 10 year term serially maturing from 2015 to 2021. We were in compliance with all covenants of the Shelf Agreement as of December 31, 2013.

Collateralized Borrowings

Collateralized borrowings represent deferred sales proceeds on certain leasing transactions with third-party leasing companies. These transactions are accounted for as borrowings, with the related assets capitalized as property, plant and equipment and depreciated straight-line over the lease term.

Capital Lease Obligations

Capital lease obligations outstanding are primarily related to sale-leaseback transactions with third-party leasing companies whereby we sell our manufactured equipment to the leasing company and lease it back. The equipment covered by these leases is rented to our customers over the lease term.

The aggregate maturities of our outstanding debt including capital lease obligations as of December 31, 2013, are as follows:
