 Act or we become aware of such ineligibility and, in either case, a successor is not appointed by us within 90 days; or (2) an event of default
has occurred and is continuing and the registrar has received a request from DTC; or (3) the applicable prospectus supplement provides otherwise with respect to a particular series.

Unless otherwise indicated in the applicable prospectus supplement, definitive debt securities will be issued in denominations of $1,000 or
