Revolving Credit Facility

On November 2, 2007, the Company entered into an asset-based credit facility, which permits borrowing up to a maximum level of $100,000. The Company entered into an Amended and Restated Credit and Security Agreement and a Second Amended and Restated Credit and Security Agreement on September 20, 2010 and December 1, 2011, respectively.

On September 12, 2014, the Company entered into a Third Amended and Restated Credit Agreement (the “Amended Agreement”). The Amended Agreement provides for a $300,000 revolving credit facility, which replaces the Company’s existing $100,000 asset-based credit facility and includes a letter of credit subfacility, swing line subfacility and multicurrency subfacility. The amended revolving credit facility (the “Credit Facility”) also has an accordion feature which allows the Company to increase the availability by up to $80,000 upon the satisfaction of certain conditions. The Amended Agreement extends the termination date of the Company’s Credit Facility to September 12, 2019 from December 1, 2016. On March 26, 2015, the Company entered into Amendment No. 1 (the “Amendment”) to the Amended Agreement which modified the definition of Consolidated EBITDA to allow for the add back of cash premiums and other non-cash charges related to the amendment and restatement of the Amended Agreement and the early extinguishment of the Company’s 9.5% Senior Secured Notes totaling $10,507 both of which occurred in second half of 2014. Consolidated EBITDA is used in computing the Company’s leverage ratio and interest coverage ratio which are covenants within the Amended Agreement.

Borrowings under the Amended Agreement will bear interest at either the Base Rate, as defined, or the LIBOR Rate, at the Company’s option, plus the applicable margin as set forth in the Amended Agreement. The Company is also subject to a commitment fee ranging from 0.20% to 0.35% based on the Company’s leverage ratio. The agreement governing our Credit Facility requires the Company to maintain a maximum leverage ratio of 3.00 to 1.00, and a minimum interest coverage ratio of 3.50 to 1.00 and places a maximum annual limit on capital expenditures. The Amended Agreement also contains other affirmative and negative covenants and events of default that are customary for credit arrangements of this type including covenants which place restrictions and/or limitations on the Company’s ability to borrow money, make capital expenditures and pay dividends.

The Company was in compliance with all credit facility covenants at March 31, 2015 and December 31, 2014.
