Such supplemental indenture shall contain the provisions, concerning the possession, control, release and substitution of encumbered and pledged property and securities and other appropriate matters which are required or permitted by the Trust Indenture Act (as in effect at the date of execution of such supplemental indenture) to be included in a secured indenture qualified under the Trust Indenture Act and may also contain such additional and mandatory provisions permitted by the Trust Indenture Act as the Company shall deem advisable or appropriate. Section 10.9 Waiver of Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 10.7 or 10.8 hereof, inclusive, with respect to the Notes if before the time for such compliance, the Holders of at least a majority in principal amount of the Notes outstanding, by act of such Holders, either shall waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the rights and protections of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.”
