Rights attached to the Securities

Potential return: The Securities will give each holder of Securities the right to receive potential return on the Securities, together with certain ancillary rights such as the right to receive notice of certain determinations and events and the right to vote on some (but not all) amendments to the terms and conditions of the Securities. The potential return will be in the forms of: (i) one or more Interest Amounts, (ii) an Autocall Cash Settlement Amount, and/or (iii) a Final Cash Settlement Amount, provided that if the Securities are early terminated, the potential return may be in the form of an Early Cash Settlement Amount instead.

Events of default: If the Issuer fails to make any payment due under the Securities or breaches any other term and condition of the Securities in a way that is materially prejudicial to the interests of the holders (and such failure is not remedied within 30 calendar days, or, any interest, has not been paid within 14 calendar days of the due date), or the Issuer is subject to a winding-up order, then (subject, in the case of interest, to the Issuer being prevented from payment for a mandatory provision of law) the Securities will become immediately due and payable, upon notice being given by the holder.

Limitations on rights

Early settlement following certain disruption events or due to unlawfulness or impracticability: The Issuer may redeem the Securities prior to their Scheduled Settlement Date following the occurrence of certain disruption events or extraordinary events concerning the Issuer, its hedging arrangements, the Underlying Asset(s), taxation or the relevant currency of the Securities, or if it determines an unlawfulness or impracticability event has occurred. In such case, investors will receive an "Early Cash Settlement Amount" equal to the fair market value of the Securities prior to their redemption.

Certain additional limitations:

·        Notwithstanding that the Securities are linked to the performance of the Underlying Asset(s), holders do not have any rights in respect of the Underlying Asset(s).

·        The terms and conditions of the Securities permit the Issuer and the Determination Agent (as the case may be), on the occurrence of certain events and in certain circumstances, without the holders' consent, to make adjustments to the terms and conditions of the Securities, to redeem the Securities prior to maturity, to postpone or obtain alternative valuation of the Underlying Asset(s) or to postpone scheduled payments under the Securities, to change the currency in which the Securities are denominated, to substitute the Underlying Asset(s), to substitute the Issuer with another permitted entity subject to certain conditions, and to take certain other actions with regard to the Securities and the Underlying Asset(s).

·        The Securities contain provisions for calling meetings of holders to consider matters affecting their interests generally and these provisions permit defined majorities to bind all holders, including holders who did not attend and vote at the relevant meeting and holders who voted in a manner contrary to the majority.

Governing law

The Securities will be governed by English law and the rights thereunder will be construed accordingly.

Description of the calculation of potential return on the Securities

Underlying Assets: The return on, and value of, Securities will be linked to the performance of one or more specified equity indices, shares, depository receipts, exchange traded funds, mutual funds, other indices (of one or more types of component assets) sponsored by Barclays Bank PLC (a "Barclays Index"), reference rate used to determine an interest rate, an inflation index, or a combination of these. The underlying assets for the Securities are: FTSE 100 Index and EURO STOXX 50® Index (each, an "Underlying Asset").

Calculation Amount: Calculations in respect of amounts payable under the Securities are made by reference to the "Calculation Amount", being GBP 1 per Security. Where the Calculation Amount is different from the specified denomination of the Securities, the amount payable will be scaled accordingly.

Indicative amounts: If the Securities are being offered by way of a Public Offer and any specified product values are not fixed or determined at the commencement of the Public Offer (including any amount, level, percentage, price, rate or other value in relation to the terms of the Securities which has not been fixed or determined by the commencement of the Public Offer), these specified product values will specify an indicative amount, indicative minimum amount, an indicative maximum amount or any combination thereof. In such case, the relevant specified product value(s) shall be the value determined based on market conditions by the Issuer on or around the end of the Public Offer. Notice of the relevant specified product value will be published prior to the Issue Date.

Determination Agent: Barclays Bank PLC will be appointed to make calculations and determinations with respect to the Securities.

__________________

A - Interest

During the term of the Securities, the Securities pay Phoenix without memory interest.

Phoenix without memory interest: Each Security will only pay interest in respect of an Interest Valuation Date if the Interest Valuation Price of every Underlying Asset on such Interest Valuation Date is greater than or equal to its corresponding Interest Barrier. If this occurs, the amount of interest payable with respect to that Interest Valuation Date is calculated by multiplying the fixed rate of 0.62% by the Calculation Amount.

The term "Interest Barrier" means in respect of an Interest Valuation Date and an Underlying Asset, the Interest Barrier Percentage (being 80.00%) multiplied by the Initial Price_(Interest) of such Underlying Asset.

The term "Interest Valuation Price" means, in respect of an Interest Valuation Date and an Underlying Asset, the closing level of such Underlying Asset in respect of such Interest Valuation Date

Interest will be payable on the corresponding Interest Payment Date set out in the table below. Each Interest Valuation Date and Interest Barrier is as follows:

_____________________

B- Automatic Settlement (Autocall)

The Securities will automatically redeem if the Autocall Performance of the Relevant Underlying Asset is greater than or equal to its corresponding Autocall Barrier in respect of any Autocall Valuation Date. If this occurs, an "Automatic Settlement (Autocall) Event" will be determined and you will receive an "Autocall Cash Settlement Amount" equal to the Calculation Amount multiplied by the Autocall Settlement Percentage (being 100.00%) payable on the Autocall Settlement Date corresponding to such Autocall Valuation Date. The relevant Autocall Settlement Date may be postponed following the postponement of an Autocall Valuation Date due to a disruption event.

Each Autocall Valuation Date and the corresponding Autocall Barrier is as follows:

"Autocall Barrier": means, in relation to a Relevant Underlying Asset and an Autocall Valuation Date, the Autocall Barrier Percentage applicable in respect of such Autocall Valuation Date.

"Autocall Performance": means, in respect of an Autocall Valuation Date, the Autocall Valuation Price divided by the Initial Price_(Settlement) in relation to the Worst Performing Underlying Asset (the "Relevant Underlying Asset").

Autocall Valuation Price" means, in respect of an Autocall Valuation Date and an Underlying Asset, the closing level of such Underlying Asset in respect of such Autocall Valuation Date.

See "C - Final Settlement" below for the definitions of "Worst Performing Underlying Asset" and "Asset Performance", respectively.

_________

C - Final Settlement

If the Securities have not otherwise redeemed, each Security will be redeemed on the Scheduled Settlement Date by payment of the Final Cash Settlement Amount.

The Scheduled Settlement Date may be postponed following the postponement of the Final Valuation Date due to a disruption event.

The "Final Cash Settlement Amount" is calculated as follows:

(i)     if a Knock-in Trigger Event has not occurred, 100% multiplied by the Calculation Amount;

(ii)    otherwise, an amount calculated by dividing the Final Performance by the Strike Price Percentage, (being 100.00) (SPP) and multiplying the result by the Calculation Amount.

Where:

"Knock-in Trigger Event" shall be deemed to have occurred if the level of any Underlying Asset in respect of the Trigger Event Observation Date (being 14 August 2031) is below the Knock-in Barrier Price (Initial Price_(Settlement) multiplied by the Knock-in Barrier Percentage (being 65.00%)) of such Underlying Asset.

"Final Performance" means the Final Valuation Price divided by the Initial Price_(Settlement) each in respect of the Worst Performing Underlying Asset as calculated in respect of the Final Valuation Date.

"Final Valuation Date" means 14 August 2031, subject to adjustment.

"Final Valuation Price" means, in respect of an Underlying Asset, the closing level in respect of the Underlying Asset on the Final Valuation Date.

"Worst Performing Underlying Asset" means, in respect of any scheduled trading day, the Underlying Asset with the lowest Asset Performance on such day.

"Asset Performance" means, in respect of an Underlying Asset and any day, the closing level of such Underlying Asset on such day divided by its Initial Price.

Status of the Securities

The Securities are direct, unsubordinated and unsecured obligations of the Issuer and rank equally among themselves.

Description of restrictions on free transferability of the Securities

The Securities are offered and sold outside the United States to non-U.S. persons in reliance on Regulation S under the Securities Act and must comply with transfer restrictions with respect to the United States. Securities held in a clearing system will be transferred in accordance with the rules, procedures and regulations of that clearing system. Subject to the foregoing, the Securities will be freely transferable.

Application is expected to be made by the Issuer (or on its behalf) for the Securities to be admitted to trading on the regulated market of the London Stock Exchange.

The Securities are subject to the following key risks:

·        You may lose some or all of your investment in the Securities: Investors are exposed to the credit risk of Barclays Bank PLC. As the Securities do not constitute a deposit and are not insured or guaranteed by any government or agency or under the UK Government credit guarantee scheme, all payments or deliveries to be made by Barclays Bank PLC as Issuer under the Securities are subject to its financial position and its ability to meet its obligations. The Securities constitute unsubordinated and unsecured obligations of the Issuer and rank pari passu with each and all other current and future unsubordinated and unsecured obligations of the Issuer. The terms of the Securities do not provide for a scheduled minimum payment at maturity and as such, depending on the performance of the Underlying Asset(s), you may lose some or all of your investment. You may also lose some or all of your investment if: (a) you sell your Securities before their scheduled maturity; (b) your Securities are early redeemed in certain extraordinary circumstances; or (c) the terms and conditions of your Securities are adjusted such that the amount payable or property deliverable to you is less than your initial investment.

·        There are risks associated with the valuation, liquidity and offering of the Securities: The market value of your Securities may be significantly lower than the issue price since the issue price may take into account the Issuer's and/or distributor's profit margin and costs in addition to the fair market value of the Securities. The market value of your Securities may be affected by the volatility, level, value or price of the Underlying Asset(s) at the relevant time, changes in interest rates, the Issuer's financial condition and credit ratings, the supply of and demand for the Securities, the time remaining until the maturity of the Securities and other factors. The price, if any, at which you will be able to sell your Securities prior to maturity may be substantially less than the amount you originally invested. Your Securities may not have an active trading market and the Issuer may not be under any obligation to make a market or repurchase the Securities prior to redemption. The Issuer may withdraw the public offer at any time. In such case, where you have already paid or delivered subscription monies for the relevant Securities, you will be entitled to reimbursement of such amounts, but will not receive any remuneration that may have accrued in the period between their payment or delivery of subscription monies and the reimbursement of the Securities.

·        You are subject to risks associated with the determination of amounts payable under the Securities:

The Securities bear interest at a rate that is contingent upon the performance of the Underlying Asset and may vary from one Interest Payment Date to the next. You may not receive any interest payments if the Underlying Asset do not perform as anticipated.

The Final Cash Settlement Amount is based on the performance of the Underlying Asset(s) as at the final valuation date only (rather than in respect of multiple periods throughout the term of the Securities). This means you may not benefit from any movement in level of the Underlying Asset(s) during the term of the Securities that is not maintained in the final performance as at the final valuation date.

You are exposed to the performance of every Underlying Asset. Irrespective of how the other Underlying Assets perform, if any one or more Underlying Assets fail to meet a relevant threshold or barrier for the payment of interest or the calculation of any redemption amount, you might receive no interest payments and/or could lose some or all of your initial investment.

The calculation of amount payable depends on the level, value or price of the Underlying Asset(s) reaching or crossing a 'barrier' during a specified period or specified dates during the term of the Securities. This means you may receive less (or, in certain cases, more) if the level, value or price of the Underlying Asset(s) crosses or reaches (as applicable) a barrier, than if it comes close to the barrier but does not reach or cross it (as applicable), and in certain cases you might receive no interest payments and/or could lose some or all of your investment.

The Securities reference a basket of Underlying Assets, each of which demonstrates unique risk characteristics. If the Underlying Assets are correlated, the performance of the Underlying Asset(s) in the basket can be expected to move in the same direction. If the performance of a basket gives a greater 'weight' to a basket constituent as compared to other basket constituents, the basket performance will be more affected by changes in the value of that particular basket constituent than a basket which apportions an equal weight to each basket constituent. The performance of basket constituents may be moderated or offset by one another. This means that, even in the case of a positive performance of one or more constituents, the performance of the basket as a whole may be negative if the performance of the other constituents is negative to a greater extent.

·        Your Securities are subject to adjustments and early redemption: Pursuant to the terms and conditions of the Securities, following the occurrence of certain disruption events or extraordinary events concerning the Issuer, its hedging arrangements, the Underlying Asset(s), taxation or the relevant currency of the Securities, the Determination Agent or the Issuer may take a number of remedial actions, including estimating the level of the Underlying Asset, substituting the Underlying Asset, and making adjustments to the terms and conditions of the Securities. Any of such remedial action may change the economic characteristics of the Securities and have a material adverse effect on the value of and return on the Securities. If no remedial action can be taken, or it is determined that an unlawfulness or impracticability event has occurred, the Issuer may early redeem the Securities by payment of an Early Cash Settlement Amount. If early redemption occurs, you may lose some or all of your investment because the Early Cash Settlement Amount may be lower than the price at which you purchase the Securities, or may even be zero. You will also lose the opportunity to participate in any subsequent positive performance of the Underlying Asset(s) and be unable to realise any potential gains in the value of the Securities. You may not be able to reinvest the proceeds from an investment at a comparable return and/or with a comparable interest rate for a similar level of risk.

·        Risks relating to Securities linked to the Underlying Asset: The return payable on the Securities is linked to the change in value of the Underlying Asset over the life of the Securities. Any information about the past performance of any Underlying Asset should not be taken as an indication of how prices will change in the future. You will not have any rights of ownership, including, without limitation, any voting rights or rights to receive dividends, in respect of any Underlying Asset.

·        Risks relating to Underlying Asset(s) that are equity indices: Equity indices are composed of a synthetic portfolio of shares and provide investment diversification opportunities, but will be subject to the risk of fluctuations in both equity prices and the value and volatility of the relevant equity index. The Securities are linked to equity indices, and as such may not participate in dividends or any other distributions paid on the shares which make up such indices. Accordingly, you may receive a lower return on the Securities than you would have received if you had invested directly in those shares. The index sponsor can add, delete or substitute the components of an equity index at its discretion, and may also alter the methodology used to calculate the level of such index. These events may have a detrimental impact on the level of that index, which in turn could have a negative impact on the value of and return on the Securities.

·        The Underlying Asset(s) are 'benchmarks' for the purposes of the UK Benchmarks Regulation (Regulation (EU) 2016/1011 as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended)): Pursuant to the UK Benchmarks Regulation, an Underlying Asset may not be used in certain ways by a supervised entity if its administrator does not obtain or maintain authorisation or registration (or, if a third country entity, does not satisfy the "equivalence" conditions or does not obtain or maintain "recognition" or "endorsement" after the transitional provision expires on 31 December 2030). If this happens, a disruption event will occur and the Securities may be early redeemed. Further, the methodology or other terms of an Underlying Asset could be changed in order to comply with the requirements of the UK Benchmarks Regulation, and such changes could reduce or increase the level or affect the volatility of the published level of such Underlying Asset, which may in turn lead to adjustments to the terms of the Securities or early redemption.

·        Taxation risks: The levels and basis of taxation on the Securities and any reliefs for such taxation will depend on your individual circumstances and could change at any time over the life of the Securities. This could have adverse consequences for you and you should therefore consult your own tax advisers as to the tax consequences to you of transactions involving the Securities.
