Designation of Restricted and Unrestricted Subsidiaries

The limitation on designation of Restricted Subsidiaries and Unrestricted Subsidiaries ensures that the various other covenants are not thwarted through the designation and redesignation of Restricted Subsidiaries and Unrestricted Subsidiaries. As a general rule, all subsidiaries of the Issuer are Restricted Subsidiaries unless a subsidiary is listed as an Unrestricted Subsidiary in the indenture or the Issuer subsequently expressly designates a Restricted Subsidiary as an Unrestricted Subsidiary in accordance with the requirements of the indenture.
