Execution and Delivery of Subsidiary Guarantee To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Subsidiary Guarantor hereby agrees that a notation of such Subsidiary Guarantee in substantially the form included in Exhibit E attached hereto shall be endorsed by an Officer of such Subsidiary Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Subsidiary Guarantor by its President or one of its Vice Presidents. Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee. If an Officer whose signature is on this Indenture or on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors.
