Pricing Term Sheet

*Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

**Note: We expect that delivery of the notes will be made to investors on or about February 6, 2023, which will be the fifth business day following the date of this final term sheet (such settlement being referred to as “T+5”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of the prospectus supplement or the next two succeeding business days will be required, by virtue of the fact that the notes initially settle in T+5, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on the date of the prospectus supplement or the next two succeeding business days should consult their advisors.

The notes will be represented by beneficial interests in fully registered permanent global notes (the “international global notes”) without interest coupons attached, which will be registered in the name of, and shall be deposited on or about February 6, 2023 with a common depositary for, and in respect of interests held through, Euroclear Bank, S.A./N.V., as operator of the Euroclear System (“Euroclear”), and Clearstream Banking, société anonyme (“Clearstream”). Any notes represented by global notes held by a nominee of Euroclear or Clearstream will be subject to the then applicable procedures of Euroclear and Clearstream, as applicable. Euroclear and Clearstream’s current practice is to make payments in respect of global notes to participants of record that hold an interest in the relevant global notes at the close of business on the date that is the clearing system business day (for these purposes, Monday to Friday inclusive except December 25^th and January 1^st) immediately preceding each applicable interest payment date.
