Transfers between participants in DTC will be effected in the ordinary
way in accordance with DTC rules and procedures and will be settled in same-day funds.

We expect
that DTC will take any action permitted to be taken by a holder of bonds only at the direction of one or more participants to whose account the DTC interests in a global bond is credited and only in respect of such portion of the aggregate principal
amount of bonds as to which such participant or participants has or have given such direction. However, if there is an event of default under the bonds, DTC will exchange the applicable global bond for certificated bonds, which it will distribute to
its participants.

S-14

A global bond is exchangeable for definitive bonds in registered certificate form if:

| • |     | DTC (i) notifies us that it is unwilling or unable to continue as depositary for the global bonds, and we                                                                 
 fail to appoint a successor depositary, or (ii) has ceased to be a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”); |

| • |     | at our option, we notify the trustees in writing that we have elected to cause the issuance of the certificated 
 securities; or                                                                                                  |

| • |     | there has occurred and is continuing a default or event of default with respect to the bonds. |

In addition, beneficial interests in a global bond may be exchanged for certificated securities upon prior written notice given to the trustees by or on behalf of DTC in accordance with the first mortgage bond indenture. In all cases, certificated securities delivered in exchange for any global bond or beneficial interests in global bonds will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures). Certificated securities may be presented for registration, transfer and exchange at The Bank of New York Mellon Trust Company, N.A., Chicago, Illinois, or the office or agency designated for such purpose.
