 DTC, on the procedures of the participant through which you own your interest, to exercise any rights of a holder of notes under the indenture or a global note.                                                                                         |

Investors will be able to make and receive payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through Euroclear and Clearstream only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States. In addition, because of time-zone differences, U.S. investors who wish to transfer their beneficial interests in the global notes held through Clearstream or Euroclear, or to receive or make a payment or delivery or exercise any other right with respect to those interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, these investors may need to exercise rights that expire on a particular day before the expiration date. In addition, investors who hold their interests through
