Unless otherwise provided in any applicable prospectus supplement, the following section is a summary of the principal terms and provisions that are included in the indenture, a form of which is included as an exhibit to the registration statement of which this prospectus forms a part. This summary is not complete and is subject to, and qualified in its entirety by, reference to the terms and provisions of the indenture. If this summary refers to particular provisions in the indenture, such provisions, including the definition of terms, are incorporated by reference in this prospectus as part of this summary.

The indenture does not limit the amount of debt securities or any other debt that may be incurred by any issuer or any guarantor.

The debt securities issued by any issuer will be such issuer’s unsecured obligations.
