 of debt securities then outstanding, unless the holders have offered the trustee security or indemnity satisfactory to it (Section 602). Subject to these provisions for the indemnification of the trustee, the holders of not less than a majority in principal amount of all outstanding debt securities of any series under the applicable indenture (except in respect of certain events of default related to bankruptcy or insolvency, the holders of a majority in principal amount of all outstanding debt securities under the applicable indenture) will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or of exercising any trust or power conferred upon the trustee. The trustee may, however, refuse to follow any direction which conflicts with any law or the applicable indenture, which may involve the trustee in personal liability or which may be unduly prejudicial to the holders of debt securities of the applicable series not joining in the direction, and the trustee may take any other action deemed proper by the trustee which is not inconsistent with the direction (Section 512). Within 120 days after the close of each fiscal year, we must deliver to the trustee a certificate, signed by one of several specified officers, stating that officer’s knowledge of our compliance with all the conditions and covenants under the applicable indenture, and, in the event of any noncompliance, specifying the noncompliance and the nature and status of the noncompliance (Section 1006).

| • |     | to add events of default for the benefit of the holders of all or any series of debt securities; |

| • |     | to add or change any provisions of the indenture to facilitate the issuance of, or to liberalize the terms of,
