Maintenance of Office or Agency The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment or, if applicable, for conversion, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company or any Subsidiary Guarantor in respect of the Securities of that series or any Subsidiary Guarantee and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and each of the Company and the Subsidiary Guarantors hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.
