### DESCRIPTION OF SUBORDINATED DEBT SECURITIES

#### General
We may issue one or more series of subordinated debt securities pursuant to this prospectus. We may issue the subordinated debt securities under an indenture (the “Subordinated Indenture”), to be entered into in the future among us, the subsidiary guarantors of such debt securities, if any, and The Bank of New York Mellon Trust Company, N.A., or another entity, as trustee (“Subordinated Indenture Trustee”). The form of Subordinated Indenture is included as an exhibit to the registration statement of which this prospectus is a part.

Below is a description of certain general terms of the subordinated debt securities. The description is not complete and is subject to and qualified in its entirety by reference to the Subordinated Indenture. The particular terms of a series of subordinated debt securities will be described in a prospectus supplement and, if applicable, a pricing supplement. Capitalized terms used but not defined in this summary have the meanings specified in the Subordinated Indenture.

The subordinated debt securities will be unsecured and will be subordinated and junior in priority of payment to our Senior Indebtedness (as defined below). The Subordinated Indenture is subject to the Trust Indenture Act. The Subordinated Indenture does not limit the amount of Senior Indebtedness or subordinated debt securities which we may issue, nor does it limit us or our subsidiaries from issuing any debt.

Each prospectus supplement, together with a pricing supplement, if applicable, will describe the terms relating to a series of subordinated debt securities, which may include
