(7)	Senior Secured Credit Facilities

On June 10, 2005, we entered into a first lien credit agreement with Merrill Lynch, Pierce Fenner & Smith, Incorporated, as syndication agent (“Merrill Lynch”), Wachovia Bank, National Association, as documentation agent (“Wachovia”), Lehman Commercial Paper Inc., as administrative agent (“Lehman”), and certain other lenders. The First Lien Credit Facility consisted of a term loan in the amount of $325.0 million, payable in twenty-eight consecutive quarterly installments commencing on June 30, 2005. The amount of the quarterly installment due on each such payment date is equal to 0.25% of the original principal balance of the term loan funded on June 10, 2005, which is approximately $0.8 million. The term loan was due and payable on June 10, 2012. On February 7, 2012 we repaid and terminated the First Lien Credit Facility (see note 8).
