* The graph and table above assume a hypothetical maximum payment at maturity of $1,127.00 per security (112.70% of the stated principal amount) and reflect the participation rate of 100%. The actual maximum payment at maturity will be determined on the pricing date. |
Our estimated value of the securities on the pricing date, based
on our internal pricing models, is expected to be between $919.90 and $969.90 per security. The estimated value is expected to be less
than the initial issue price of the securities. See “Additional Information Regarding Our Estimated Value of the Securities”
in the accompanying pricing supplement.

acknowledges, accepts, agrees to be bound by and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority.

Risk Factors
An investment in the securities involves significant risks. We urge
you to consult your investment, legal, tax, accounting and other advisors before you invest in the securities. Some of the risks that
apply to an investment in the securities are summarized below, but we urge you to read the more detailed explanation of risks relating
to the securities generally in the “Risk Factors” sections in the accompanying pricing supplement and the prospectus supplement.
You should not purchase the securities unless you understand and can bear the risks of investing in the securities.
Risks Relating to the Securities Generally
| · | The securities do not pay interest and may not pay more than
the minimum payment at maturity. |
| · | The appreciation potential of the securities is limited by
the maximum payment at maturity. |
| · | Any payment on the securities will be determined based on
the closing levels of the underlier on the dates specified. |
| · | Investing in the securities is not equivalent to investing
in the underlier or the securities composing the underlier. |
Risks Relating to the Issuer
| · | Any payments on the securities are subject to issuer credit
risk. |
| · | You may lose some or all of your investment if any U.K. Bail-in
Power is exercised by the relevant U.K. resolution authority. |
Risks Relating to the Underlier
| · | Adjustments to the underlier could adversely affect the value
of the securities. |
| · | Governmental legislative or regulatory actions, such as sanctions,
could adversely affect your investment in the securities. |
| · | We may accelerate the securities if a change-in-law event
occurs. |
Risks Relating to Conflicts of Interest
| · | Hedging and trading activity by the issuer and its affiliates
could potentially adversely affect the value of the securities. |
| · | We and our affiliates, and any dealer participating in the
distribution of the securities, may engage in various activities or make determinations that could materially affect your securities in
various ways and create conflicts of interest. |
Risks Relating to the Estimated Value of the Securities and the
Secondary Market
| · | The securities will not be listed on any securities exchange,
and secondary trading may be limited. |
| · | The market price of the securities will be influenced by
many unpredictable factors. |
| · | The estimated value of your securities is expected to be
lower than the initial issue price of your securities. |
| · | The estimated value of your securities might be lower if
such estimated value were based on the levels at which our debt securities trade in the secondary market. |
| · | The estimated value of the securities is based on our internal
pricing models, which may prove to be inaccurate and may be different from the pricing models of other financial institutions. |
| · | The estimated value of your securities is not a prediction
of the prices at which you may sell your securities in the secondary market, if any, and such secondary market prices, if any, will likely
be lower than the initial issue price of your securities and may be lower than the estimated value of your securities. |
| · | The temporary price at which we may initially buy the securities
in the secondary market and the value we may initially use for customer account statements, if we provide any customer account statements
at all, may not be indicative of future prices of your securities. |

about the Securities—Tax considerations” in the accompanying pricing supplement.
