SECTION 13.07. Modification Without Supplemental Indenture.
To the extent, if any, that the terms of any particular series of Bonds shall have been established in or pursuant to a Board Resolution or an Officer’s Certificate pursuant to a supplemental indenture or a Board Resolution as contemplated by Section 3.01, and not in a supplemental indenture, additions to, changes in or the elimination of any of such terms may be effected by means of a supplemental Board Resolution or a supplemental Officer’s Certificate, as the case may be, delivered to, and accepted by, the Trustee; provided, however, that such supplemental Board Resolution or supplemental Officer’s Certificate shall not be accepted by the Trustee or otherwise be effective unless all conditions set forth in this Indenture which would be required to be satisfied if such additions, changes or elimination were contained in a supplemental indenture shall have been appropriately satisfied. Upon the acceptance thereof by the Trustee, any such supplemental Board Resolution or supplemental Officer’s Certificate shall be deemed to be a “supplemental indenture” for purposes of Section 13.04 and 13.06.
