The following briefly summarizes the material terms
that will generally be included in a debt warrant agreement. However, we may include different terms in the debt warrant agreement for
any particular series of debt warrants and such other terms and all pricing and related terms will be disclosed in the applicable prospectus
supplement. You should read the particular terms of any debt warrants that are offered by us and the related debt warrant agreement which
will be described in more detail in the applicable prospectus supplement. The prospectus supplement will also state whether any of the
generalized provisions summarized below do not apply to the debt warrants being offered.

General

We may issue warrants for the purchase of our debt
securities. As explained below, each debt warrant will entitle its holder to purchase debt securities at an exercise price set forth in,
or to be determined as set forth in, the applicable prospectus supplement. Debt warrants may be issued separately or together with debt
securities.

The debt warrants are to be issued under debt warrant
agreements to be entered into by us and one or more banks or trust companies, as debt warrant agent, all as will be set forth in the applicable
prospectus supplement. At or around the time of an offering of debt warrants, a form of debt warrant agreement, including a form of debt
warrant certificate representing the debt warrants, reflecting the alternative provisions that may be included in the debt warrant agreements
to be entered into with respect to particular offerings of debt warrants, will be filed by amendment as an exhibit to the registration
statement of which this prospectus forms a part.
