 we may elect:

| • |     | to defease and be discharged from any and all obligations with respect to those debt securities, which we refer 
 to as “defeasance;” or                                                                                          |

| • |     | with respect to any debt securities, to be released from certain covenant obligations as described in the related             
 prospectus supplement, as may be provided for under Section 301 of the indenture, which we refer to as “covenant defeasance.” |

In the case of defeasance we will still retain some obligations in respect of the debt securities, including our obligations:

| • |     | to pay additional amounts, if any, upon the occurrence of certain events of taxation, assessment or governmental 
 charge with respect to payments on the debt securities;                                                          |

23

| • |     | to register the transfer or exchange of the debt securities; |

| • |     | to replace temporary or mutilated, destroyed, lost or stolen debt securities; and |

| • |     | to maintain an office or agency with respect to the debt securities and to hold monies for payment in trust. |

After a covenant defeasance, any omission to comply with the obligations or covenants that have been defeased shall not constitute a default or an event of default with respect to the debt securities. To elect either defeasance or covenant defeasance we must deposit with the trustee, in trust, an amount, in U.S. dollars or in the foreign currency in which the relevant debt securities are payable at stated maturity, or in government obligations, as defined below, or both, applicable to such debt securities. The deposit will provide through the scheduled payment of principal and interest in accordance with their terms, money in an amount sufficient to pay the principal of and any premium and interest on (and, to the extent that (1) the debt securities of such series provide for the payment of additional amounts and (2) we may reasonably determine the amount of any such additional amounts at the time of deposit (in the exercise of our sole discretion), any such additional amounts with respect to) such debt securities, and any mandatory sinking fund or analogous payments thereon, on their scheduled due dates. In addition, we can only elect defeasance or covenant defeasance if, among other things:

| • |     | the defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, 
 the indenture or any other material agreement or instrument
