 to the trustee for cancellation
all debt securities of that series (with certain limited exceptions) or (b) all debt securities of that series not previously delivered
to the trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or
are to be called for redemption within one year, and we have deposited with the trustee the entire amount sufficient to pay at maturity
or upon redemption all such debt securities.

In addition, we have a “legal defeasance
option” (pursuant to which we may terminate, with respect to the debt securities of a particular series, all of our obligations
under such debt securities and the indenture with respect to such debt securities) and a “covenant defeasance option” (pursuant
to which we may terminate, with respect to the debt securities of a particular series, our obligations with respect to such debt securities
under certain specified covenants contained in the indenture). If we exercise our legal defeasance option with respect to a series of
debt securities, payment of such debt securities may not be accelerated because of an event of default. If we exercise our covenant defeasance
option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an event of default
related to the specified covenants.

We may exercise our legal defeasance option or
our covenant defeasance option with respect to the debt securities of a series only if we irrevocably deposit in trust with the trustee
cash or U.S. government obligations (as defined in the indenture) for the payment of principal, premium, if any, and interest with respect
to such debt securities to maturity or redemption, as the case may be. In addition, to exercise either of our defeasance options, we must
comply with certain other conditions, including the delivery to the trustee of an opinion of counsel to the effect that the holders of
debt securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance
and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if
such defeasance had not occurred (and, in the case of legal defeasance only, such opinion of counsel must be based on a ruling from the
Internal Revenue Service or other change in applicable Federal income tax law).
