The Notes described in this Pricing Term Sheet are not intended to be offered or sold to and should not be offered or sold to any retail investor in the European Economic Area (“EEA”) or in the United Kingdom. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of MiFID II or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended or superseded, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. No key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes described in this Pricing Term Sheet or otherwise making them available to retail investors in the EEA or in the United Kingdom has been prepared. Offering or selling the Notes described in this Pricing Term Sheet or otherwise making them available to any retail investor in the EEA or in the United Kingdom may be unlawful.

Solely for the purposes of the product approval process of each of the manufacturers, the target market assessment in respect of the Notes described in this Pricing Term Sheet has led to the conclusion that: (i) the target market for such Notes is eligible counterparties and professional clients only, each as defined in Directive 2014/65/EU (as amended, “MiFID II”); and (ii) all channels for distribution of such Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending such Notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of such Notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

This Pricing Term Sheet should not be distributed, published or reproduced (in whole or in part) or disclosed by any recipients to any other person in the United Kingdom. Any person in the United Kingdom that is not a relevant person should not act or rely on this Pricing Term Sheet. The Notes are not being offered to the public in the United Kingdom.
