Unless otherwise specified in the applicable prospectus supplement, if, after we have deposited funds and/or government obligations to effect defeasance or covenant defeasance with respect to debt securities of any series, either:

| • |     | the holder of a debt security of that series is entitled to, and does, elect to receive payment in a currency 
 other than that in which such deposit has been made in respect of that debt security; or                      |

| • |     | a conversion event, as defined below, occurs in respect of the foreign currency in which the deposit has been 
 made,                                                                                                         |

| • |     | in the case of payments made pursuant to the first of the two items in the list above, the applicable market 
 exchange rate for the currency in effect on the second business day prior to the date of the payment; or     |

| • |     | with respect to a conversion event, the applicable market exchange rate for such foreign currency in effect, as 
 nearly as feasible, at the time of the conversion event.                                                        |

The indenture defines a “conversion event” as the cessation of use of:

| • |     | a foreign currency both by the government of the country or the confederation that issued such foreign currency                            
 and for the settlement of transactions by a central bank or other public institutions of or within the international banking community; or |
