TC:

| • |     | upon deposit of a global note with DTC’s custodian, DTC will credit portions of the principal amount of the 
 global note to the accounts of the DTC participants designated by the underwriters; and                     |

| • |     | ownership of beneficial interests in a global note will be shown on, and transfers of such interests will be                                                                                                    
 effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the global note). |

Book-Entry Procedures for Global Notes All interests in a global note will be subject to the operations and procedures of DTC. Accordingly, you must allow for sufficient time in order to comply with those operations and procedures if you wish to exercise any of your rights with respect to global notes. The operations and procedures of DTC are controlled by DTC and may be changed at any time. None of us, the trustee or any of the underwriters will be responsible for those operations or procedures. DTC has advised us that it is:

| • |     | a limited purpose trust company organized under the laws of the State of New York; |

| • |     | a “banking organization” within the meaning of the New York State Banking Law; |

| • |     | a member of the Federal Reserve System; |

| • |     | a “clearing corporation” within the meaning of the Uniform Commercial Code; and |

| • |     | a “clearing agency” registered under Section 17A of the Exchange Act. |

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC’s participants include securities brokers and dealers (including the underwriters), banks and trust companies, clearing corporations and other organizations. Indirect access to DTC’s book-entry system is also S-57

available to other “indirect participants,” such as banks, brokers, dealers and trust companies, who directly or indirectly clear through or maintain a custodial relationship with a DTC participant. Purchasers of notes who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC. So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes
