 significant changes in rates of exchange between the holder’s home currency and the yen; |

| • |     | the imposition or modification of foreign exchange controls with respect to the yen; and |

| • |     | tax consequences for you as a result of any foreign exchange gains resulting from an investment in the notes. |

We have no control over a number of factors affecting this type of note, including economic, financial and political events that are important in determining the existence, magnitude and longevity of these risks and their results. In recent years, rates of exchange for certain currencies, including the yen, have been highly volatile, and this volatility may be expected to continue in the future. Fluctuations in any particular exchange rate that have occurred in the past are not necessarily indicative of fluctuations in the rate that may occur during the term of the notes. Depreciation of the yen against the holder’s home currency could result in a decrease in the effective yield of the notes below the applicable coupon rate, and in certain circumstances, could result in a loss to the holder on a home currency basis. S-7

This description of foreign currency risks does not describe all the risks of an investment
in securities denominated in a currency other than the home currency. You should consult your own financial and legal advisors as to the risks involved in an investment in the notes.

The notes permit us to make payments in U.S. dollars if we are unable to obtain yen.

If the yen is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control then all payments in
respect of the notes will be made in U.S. dollars until the yen is again available to us. The amount payable on any date in yen will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on
the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then most recent U.S. dollar/yen exchange rate published in the Wall Street Journal
on or prior to the second business day prior to the relevant payment date or, in the event the Wall Street Journal has not published such exchange rate, the rate will be determined in our sole discretion on the basis of the most recently available
market exchange rate for yen. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes
