### DESCRIPTION OF WARRANTS
Each issue of warrants will be the subject of a warrant agreement which will contain the terms of the warrants. The warrant agreement and form of warrant will be filed as exhibits to the Registration Statement of which this prospectus forms a part. We will distribute a prospectus supplement with regard to each issue of warrants. Each prospectus supplement will describe, as to the warrants to which it relates:

•

the securities which may be purchased by exercising the warrants (which may be common stock, preferred stock, depositary shares, debt securities or units);

•

the exercise price of the warrants (which may be wholly or partly payable in cash or wholly or partly payable with other types of consideration);

•

the period during which the warrants may be exercised;

•

any provision adjusting the securities which may be purchased on exercise of the warrants and the exercise price of the warrants in order to prevent dilution or otherwise;

•

the place or places where warrants can be presented for exercise or for registration of transfer or exchange; and

•

any other material terms of the warrants.

### DESCRIPTION OF DEBT SECURITIES
The following description of our debt securities describes general terms and provisions of a series of debt securities to which any prospectus supplement may relate. When we offer to sell a series of debt securities, we will describe the specific terms of the series in the applicable prospectus supplement. If any particular terms of the debt securities of that series or the indenture described in a prospectus supplement differ from any of the terms described in this prospectus, then the terms described in the applicable prospectus supplement will supersede the terms described in this prospectus.

We may issue our debt securities either separately, or together with, or upon the conversion or exercise of or in exchange for, other securities described in this prospectus. The debt securities will be unsubordinated and, unless otherwise expressly stated in the applicable prospectus supplement, unsecured obligations and may be issued in one or more series. If so indicated in the applicable prospectus supplement, we may issue debt securities that are secured by specified collateral. Unless otherwise expressly stated or the context otherwise requires, as used in this section, the term “secured debt securities” means any debt securities that, as described in the prospectus supplement relating thereto, are secured by collateral; the term “unsecured debt securities” means any debt securities
