(16)	Guarantor Subsidiaries

The obligations under the Notes are fully and unconditionally guaranteed (except for certain release provisions including any sale or other disposition of all or substantially all of the assets of that guarantor, any sale or other disposition of the capital stock of that guarantor, if we designate any restricted subsidiary that is a guarantor to be an unrestricted subsidiary and upon legal defeasance of satisfaction and discharge of the indenture, which are considered customary), jointly and severally, by all of our current and future 100% owned domestic restricted subsidiaries (Guarantors). No other subsidiaries guarantee the Notes. The Notes and guarantees are secured by a first-priority lien on certain collateral which comprises substantially all of the Parent and Guarantors' tangible and intangible assets, subject to certain exceptions. The following tables present the balance sheets, statements of operations and statements of cash flows of the Parent, Guarantor and Non-Guarantor entities along with the eliminations necessary to arrive at the information on a consolidated basis.

General corporate expenses, including public company costs, certain amortization, corporate administration costs, acquisition-related expenses and net interest expense are included in the results of the Parent.
