Restricted subsidiary means any of our direct or indirect subsidiaries that has substantially all of its assets located in the United States and carries on substantially all of its business in the United States, or that holds substantially all of its assets in the form of ownership of other restricted subsidiaries.

| • |     | liens existing at the time the indenture became effective; |

| • |     | liens on property of an entity at the time it is merged into or consolidated with us or a restricted subsidiary
