You may exchange your debt warrant certificates
for new debt warrant certificates of different denominations but they must be exercisable for the same aggregate principal amount of debt
securities. If your debt warrant certificates are in registered form, you may present them for registration of transfer at the corporate
trust office of the debt warrant agent or any other office indicated in the applicable prospectus supplement. Except as otherwise indicated
in a prospectus supplement, before the exercise of debt warrants, holders of debt warrants will not be entitled to payments of principal
or any premium or interest on the debt securities that can be purchased upon such exercise, or to enforce any of the covenants in the
indenture relating to the debt securities that may be purchased upon such exercise.

Exercise of Debt Warrants

Unless otherwise provided in the applicable prospectus
supplement, each debt warrant will entitle the holder to purchase a principal amount of debt securities for cash at an exercise price
in each case that will be set forth in, or to be determined as set forth in, the applicable prospectus supplement. Debt warrants may be
exercised at any time up to the close of business on the expiration date specified in the applicable prospectus supplement. After the
close of business on the expiration date or any later date to which we extend the expiration date, unexercised debt warrants will become
void.

Debt warrants may be exercised as set forth in
the prospectus supplement applicable to the particular debt warrants. Upon delivery of payment of the exercise price and the debt warrant
