(h) to cure any ambiguity, to correct or supplement any provision herein which may be defective or inconsistent with any other provision herein; or to make any other additions to, deletions from or other changes to the provisions under this Indenture, provided that such additions, deletions and/or other changes shall not materially adversely affect the interests of the Holders of Bonds of any series or Tranche in any material respect; or
(i) to modify, eliminate or add to the provisions of this Indenture to such extent as shall be necessary to continue the qualification of this Indenture under the Trust Indenture Act, or under any similar federal statute enacted after March 11, 2004, and to add to this Indenture such other provisions as may be expressly permitted by the Trust Indenture Act, excluding, however the provisions referred to in Section 316(a)(2) of the Trust Indenture Act as in effect on March 11, 2004 or any corresponding provision in any similar federal statute enacted after March 11, 2004; or
(j) to supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the discharge of any series of Bonds pursuant to Section 8.02; provided that any such action shall not adversely affect the interests of the Holders of Bonds of such series or any other series of Bonds in any material respect; or

Without limiting the generality of the foregoing, if the Trust Indenture Act as in effect on the Initial Issuance Date, or at any time thereafter shall be amended and
(x) if any such amendment shall require one or more changes to any provisions hereof or the inclusion herein of any additional provisions, or shall by operation of law be deemed to effect such changes or incorporate such provisions by reference or otherwise, this Indenture shall be deemed to have been amended so as to conform to such amendment to the Trust Indenture Act, and the Company and the Trustee may, without the consent of any Holders, enter into an indenture supplemental hereto to evidence such amendment hereof; or
(y) if any such amendment shall permit one or more changes to, or the elimination of, any provisions hereof which, as of March 11, 2004 or at any time thereafter, are required by the Trust Indenture Act to be contained herein or are contained herein to reflect any provisions of the Trust Indenture Act as in effect at such date, this Indenture shall be deemed to have been amended to effect such changes or elimination, and the Company and the Trustee may, without the consent of any Holders, enter into an indenture supplemental hereto to amend this Indenture to effect such changes or elimination.
