**U.K. Bail-in Power Acknowledgment:**

Notwithstanding and to the exclusion of any other term of the securities or any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the securities (or the trustee on behalf of the holders of the securities), by acquiring the securities, each holder or beneficial owner of the securities 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.

**The Underliers**

For more information about the underliers, including historical performance information, see the accompanying pricing supplement.

**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***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The securities do not guarantee the return of any principal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· You will not receive any contingent quarterly payment for
any quarterly determination period if a coupon barrier event occurs on any scheduled trading day during that determination period with
respect to any underlier.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· You will not participate in any appreciation in the value
of any underlier.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· You are exposed to the market risk of each underlier, with
respect to both the contingent quarterly payments, if any, and the payment at maturity, if any.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Because the securities are linked to the performance of the
worst performing underlier, you are exposed to greater risks of no contingent quarterly payments and sustaining a significant loss on
your investment than if the securities were linked to just one underlier.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The securities are subject to early redemption risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Any payment on the securities will be determined based on
the closing levels of the underliers on the dates specified.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Contingent repayment of principal applies only at maturity
or upon any automatic early redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The securities are subject to volatility risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Investing in the securities is not equivalent to investing
in any or all underliers or the securities composing the underliers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Significant aspects of the tax treatment of the securities
are uncertain.

 ****

***Risks Relating to the Issuer***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Any payments on the securities are subject to issuer credit
risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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 Underliers***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Adjustments to the underliers could adversely affect the
value of the securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· There are risks associated with investments in securities
linked to the value of non-U.S. equity securities with respect to the NDX Index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· There are risks associated with investments in securities
linked to the value of non-U.S. equity securities in non-U.S. securities markets with respect to the SX5E Index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The securities do not provide direct exposure to fluctuations
in exchange rates between the U.S. dollar and the euro with respect to the SX5E Index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Governmental legislative or regulatory actions, such as sanctions,
could adversely affect your investment in the securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· We may accelerate the securities if a change-in-law event
occurs.

 ****

***Risks Relating to Conflicts of Interest***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Hedging and trading activity by the issuer and its affiliates
could potentially adversely affect the value of the securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The securities will not be listed on any securities exchange,
and secondary trading may be limited.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The market price of the securities will be influenced by
many unpredictable factors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The estimated value of your securities is expected to be
lower than the initial issue price of your securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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.
