 of any debt securities offered under such prospectus
supplement may differ from the terms we describe below, and to the extent the terms set forth in a prospectus supplement differ from the
terms described below, the terms set forth in the prospectus supplement shall control.

We may sell from time to time, in one or more
offerings under this prospectus, debt securities, which may be senior or subordinated. We will issue any such senior debt securities under
a senior indenture that we will enter into with a trustee to be named in the senior indenture. We will issue any such subordinated debt
securities under a subordinated indenture, which we will enter into with a trustee to be named in the subordinated indenture. We have
filed forms of these documents as exhibits to the registration statement, of which this prospectus is a part. We use the term “indentures”
to refer to either the senior indenture or the subordinated indenture, as applicable. The indentures will be qualified under the Trust
Indenture Act of 1939, as in effect on the date of the indenture. We use the term “debenture trustee” to refer to either the
trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

The following summaries of material provisions
of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by
reference to, all the provisions of the indenture applicable to a particular series of debt securities.

General

Each indenture provides that debt securities may
be issued from time to time in one or more series and may be denominated and payable in foreign currencies or units based on or relating
to foreign currencies. Neither indenture limits the amount of debt securities that may be issued thereunder, and each indenture provides
that the specific terms of any series of debt securities shall be set forth in, or determined pursuant to, an authorizing resolution and/or
a supplemental indenture, if any, relating to such series.

We will describe in each prospectus supplement the following terms
relating to a series of debt securities:

| · | the title or designation; |

| · | the aggregate principal amount and any limit on the amount that may be issued; |

| · | the currency or units based on or relating to currencies in which debt securities of such series are denominated 
 and the currency or units in which principal or interest or both will
