 the following are events of default with respect to a series of debt securities:

| • |     | a default in the payment of any interest on such series of debt securities when due and payable, and the 
 continuance of such default for a period of 60 days;                                                     |

| • |     | a default in the payment of principal of such series of debt securities when due and payable; |

| • |     | a default in the performance, or breach, in any material respect, of other covenants of ours in the indenture                             
 applicable to such series of debt securities that continues for 90 consecutive days after we receive notice of the default or breach; and |

| • |     | certain events of bankruptcy, insolvency or liquidation involving us. |

If an event of bankruptcy, insolvency or liquidation of us has occurred, the principal of the then-outstanding debt securities and any other amounts payable under the indenture will become immediately due and payable. If any other event of default shall occur and be continuing, either the trustee or the holders of not less than 33% in aggregate principal amount of the outstanding debt securities of all series (or, if such default is not applicable to all series of the debt securities, the holders of at least 33% in aggregate principal amount of the outstanding debt securities of all series to which such default is applicable) (in each case, voting as a single class) may declare the principal amount payable under the indenture on those then outstanding debt securities of the series affected by the default due and payable. 8

Defeasance Our obligations with respect to the payment of the principal and interest on the debt securities will terminate if we irrevocably deposit or cause to be deposited with the trustee as trust funds specifically held in trust for, and dedicated solely to, the benefit of the holders of the debt securities:

| • |     | cash, |

| • |     | U.S. government obligations, which through the scheduled payment of interest and principal in respect thereof in 
 accordance with their terms will provide, not later than one day before the due date of any payment, cash, or    |

| • |     | a combination of the foregoing, |

in each case sufficient to pay and discharge each installment of principal and interest on the debt securities. The discharge of the debt securities is subject to certain other conditions, including, without limitation,

| • |     | no event of default or event (including such deposit) which with notice or lapse of time would
