(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the holders of Securities. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment sixty (60) days after the mailing of such notice of resignation to the Securityholders, the resigning Trustee may, upon ten (10) business days notice to the Company and the Securityholders, appoint a successor identified in such notice or may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Securityholder who has been a bona fide holder of a Security or Securities for at least six (6) months may, subject to the provisions of Section 7.13, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.
