We expect to deliver the Securities on or about November 6, 2026, which will be the fourth business day following the date of this term sheet ("T+4"). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Securities on any day other than the business day preceding the settlement date may be required, by virtue of the fact that the Securities initially will settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.
