 and the purchase by us of all or substantially all of the property and assets of another corporation. These transactions are permitted if:

| • |     | the resulting or acquiring corporation, if other than us, assumes all of our responsibilities and liabilities                               
 under the indenture, including the payment of all amounts due on the debt securities and performance of the covenants in the indenture; and |

| • |     | immediately after the transaction, no event of default exists. |

Even though each indenture contains the provisions described above, we are not required by either indenture to comply with those provisions if we sell all of our property and assets to another U.S. corporation if, immediately after the sale, that corporation is one of our wholly-owned subsidiaries. If we consolidate or merge with or into any other corporation or sell all or substantially all of our assets according to the terms and conditions of each indenture, the resulting or acquiring corporation will be substituted for us in the indentures with the same effect as if it had been an original party to the indentures. As a result, the successor corporation may exercise our rights and powers under each indenture, in our name or in its own name and we will be released from all our liabilities and obligations under each indenture and under the 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 an event of default for any series of debt securities occurs and continues, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities
