 debt securities. Events of Default, Notice and Certain Rights on Default Unless otherwise stated in the applicable prospectus supplement, an “event of default,” when used with respect to any series of debt securities, means any of the following:

| • |     | failure to pay interest on any debt security of that series for 30 days after the payment is due; |

| • |     | failure to pay the principal of or any premium on any debt security of that series when due; |

| • |     | failure to deposit any sinking fund payment on debt securities of that series when due; |

| • |     | failure to perform any other covenant in the applicable indenture that applies to debt securities of that series      
 for 90 days after we have received written notice of the failure to perform in the manner specified in the indenture; |

| • |     | certain events in bankruptcy, insolvency or reorganization; or |

| • |     | any other event of default that may be specified for the debt securities of that series when that series is 
 created.                                                                                                    |

If a declaration occurs, the holders of a majority of the aggregate principal amount of the outstanding debt securities of that series can, subject to certain conditions, rescind the declaration. The prospectus supplement relating to each series of debt securities which are original issue discount securities will describe the particular provisions that relate to the acceleration of maturity of a portion of the principal amount of that series when an event of default occurs and continues. 8

An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under either indenture. Each indenture requires us to file an officers’ certificate with the trustee each year that states that certain defaults do not exist under the terms of the indenture. The trustee will transmit by mail to the holders of debt securities of a series notice of any default. Other than its duties in the case of a default, a trustee is not obligated to exercise any of its rights or powers under an indenture at the request, order or direction of any holders, unless the holders offer the trustee indemnification satisfactory to the trustee. If indemnification satisfactory to the trustee is provided, then, subject
