The unsecured indentures give us broad authority to set the particular terms of each series of debt securities, including the right to modify
certain of the terms contained in the indentures. The particular terms of a series of debt securities and the extent, if any, to which the particular terms of the issue modify the terms of the unsecured indenture will be described in the prospectus
supplement relating to the debt securities.

Each unsecured indenture contains the full legal text of the matters described in this
section. Because this section is a summary, it does not describe every aspect of the debt securities or the applicable indenture. This summary is subject to and qualified by all the provisions of the applicable indenture, including definitions of
terms used in any such indenture. Therefore, you should read carefully the detailed provisions of the unsecured indentures, which we have incorporated by reference as exhibits to the registration statement that includes this prospectus. This summary
also is subject to and qualified by the description of the particular terms of the debt securities in the applicable prospectus supplement.
