Information Concerning the Debenture Trustee

The debenture trustee, other

care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the debenture trustee

it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate

person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular
record date for the interest.

We will name in the applicable
board resolution any other
