 accounts of customers in bearer form or registered in “street name,” and will be the responsibility of each participant and not of DTC, the paying agent, or us, subject to applicable statutory or regulatory requirements. |

| • |     | Purchases of interests in a global note must be made by or through direct participants, which will receive a                                                                                                                                        
 credit for their interests on DTC’s records. Your ownership interest in a global note is in turn to be recorded on the direct and indirect participants’ records. You will not receive written confirmation from DTC of your purchase, though       
 you are expected to receive written confirmations providing details of the transaction, as well as periodic statements of your holdings, from the participant through which you entered into the transaction. Transfers of ownership interests in a 
 global note are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of the beneficial owners.                                                                                                      |

| • |     | If we redeem a global note in part, DTC’s practice is to determine by lot the amount of the interest of each 
 direct participant holding an interest in the global note to be redeemed.                                    |

| • |     | Neither DTC nor Cede (nor any other DTC nominee) will consent or vote with respect to the notes unless authorized                                                                                                                                    
 by a direct participant in accordance with DTC’s applicable procedures. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date for any action by the holders of notes. The omnibus proxy assigns 
 Cede’s consenting or voting rights to those direct participants to whose accounts the notes are credited on the record date (identified in a listing attached to the omnibus proxy).                                                                 |

 participants have, given direction.                                                                                                                                                                                                                       |
