CONSENT TO U.K. BAIL-IN POWER

Notwithstanding and to the exclusion of any other term of the Notes or any other agreements, arrangements or understandings between us and any holder or beneficial owner of the Notes (or the Trustee on behalf of the holders of the Notes), by acquiring the Notes, each holder and beneficial owner of the Notes 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.

Under the U.K. Banking Act 2009, as amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power in circumstances in which the relevant U.K. resolution authority is satisfied that the resolution conditions are met. These conditions include that a U.K. bank or investment firm is failing or is likely to fail to satisfy the Financial Services and Markets Act 2000 (the "FSMA") threshold conditions for authorization to carry on certain regulated activities (within the meaning of section 55B FSMA) or, in the case of a U.K. banking group company that is a European Economic Area ("EEA") or third country institution or investment firm, that the relevant EEA or third country relevant authority is satisfied that the resolution conditions are met in respect of that entity.

The U.K. Bail-in Power includes any write-down, conversion, transfer, modification and/or suspension power, which allows for (i) the reduction or cancellation of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Notes; (ii) the conversion of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Notes into shares or other securities or other obligations of Barclays Bank PLC or another person (and the issue to, or conferral on, the holder or beneficial owner of the Notes such shares, securities or obligations); (iii) the cancellation of the Notes and/or (iv) the amendment or alteration of the maturity of the Notes, or amendment of the amount of interest or any other amounts due on the Notes, or the dates on which interest or any other amounts become payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the Notes solely to give effect to the exercise by the relevant U.K. resolution authority of such U.K. Bail-in Power. Each holder and beneficial owner of the Notes further acknowledges and agrees that the rights of the holders or beneficial owners of the Notes are subject to, and will be varied, if necessary, solely to give effect to, the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. For the avoidance of doubt, this consent and acknowledgment is not a waiver of any rights holders or beneficial owners of the Notes may have at law if and to the extent that any U.K. Bail-in Power is exercised by the relevant U.K. resolution authority in breach of laws applicable in England.

For more information, please see "Selected Risk Considerations-Risks Relating to the Issuer-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" in this pricing supplement as well as "U.K. Bail-in Power," "Risk Factors-Risks Relating to the Securities Generally-Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail, including the exercise by the relevant U.K. resolution authority of a variety of statutory resolution powers, could materially adversely affect the value of any securities" and "Risk Factors-Risks Relating to the Securities Generally-Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority" in the accompanying prospectus supplement.

ADDITIONAL INFORMATION REGARDING OUR ESTIMATED VALUE OF THE NOTES

The range of the estimated values of the Notes referenced above may not correlate on a linear basis with the range of any other term of the Notes as may be set forth in this pricing supplement. We determined the size of such range based on prevailing market conditions, as well as the anticipated duration of the marketing period for the Notes. The final terms for the Notes will be determined on the date the Notes are initially priced for sale to the public, which we refer to as the Initial Valuation Date, based on prevailing market conditions on or prior to the Initial Valuation Date, and will be communicated to investors either orally or in a final pricing supplement.

Our internal pricing models take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize, typically including volatility, interest rates, and our internal funding rates. Our internal funding rates (which are our internally published borrowing rates based on variables such as market benchmarks, our appetite for borrowing, and our existing obligations coming to maturity) may vary from the levels at which our benchmark debt securities trade in the secondary market. Our estimated value on the Initial Valuation Date is based on our internal funding rates. Our estimated value of the Notes may be lower if such valuation were based on the levels at which our benchmark debt securities trade in the secondary market.

Our estimated value of the Notes on the Initial Valuation Date is expected to be less than the initial issue price of the Notes. The difference between the initial issue price of the Notes and our estimated value of the Notes is a result of several factors, including any sales commissions to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees (including any structuring or other distribution related fees) to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

Our estimated value on the Initial Valuation Date is not a prediction of the price at which the Notes may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the Notes in the secondary market. Subject to normal market and funding conditions, Barclays Capital Inc. or another affiliate of ours intends to offer to purchase the Notes in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value on the Initial Valuation Date for a temporary period expected to be approximately three months after the Issue Date because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes which we will no longer expect to incur over the term of the Notes. We made such discretionary election and determined this temporary reimbursement period on the basis of a number of factors, which may include the tenor of the Notes and/or any agreement we may have with the distributors of the Notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the initial Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

We urge you to read the "Selected Risk Considerations" beginning on page PS-15 of this pricing supplement.

You may revoke your offer to purchase the Notes at any time prior to the Initial Valuation Date. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to the Initial Valuation Date. In the event of any changes to the terms of the Notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.

ADDITIONAL TERMS OF THE NOTES

The Observation Dates (including the Final Valuation Date), the Contingent Coupon Payment Dates, any Call Settlement Date and the Maturity Date are subject to postponement in certain circumstances, as described under "Reference Assets-Exchange-Traded Funds-Market Disruption Events for Securities with an Exchange-Traded Fund that Holds Equity Securities as a Reference Asset," "Reference Assets-Least or Best Performing Reference Asset-Scheduled Trading Days and Market Disruption Events for Securities Linked to the Reference Asset with the Lowest or Highest Return in a Group of Two or More Equity Securities, Exchange-Traded Funds and/or Indices of Equity Securities" and "Terms of the Notes-Payment Dates" in the accompanying prospectus supplement.

In addition, the Reference Assets and the Notes are subject to adjustment by the Calculation Agent under certain circumstances, as described under "Reference Assets-Exchange-Traded Funds-Adjustments Relating to Securities with an Exchange-Traded Fund as a Reference Asset" in the accompanying prospectus supplement.

HYPOTHETICAL EXAMPLES OF CONTINGENT COUPONS AND UNPAID COUPON AMOUNTS THAT MAY BE PAYABLE DURING THE TERM OF THE NOTES

The following examples demonstrate the circumstances under which you may receive a Contingent Coupon and/or any Unpaid Coupon Amounts on hypothetical Contingent Coupon Payment Dates during the term of the Notes. The numbers appearing in these tables are purely hypothetical and are provided for illustrative purposes only. These examples do not take into account any tax consequences from investing in the Notes and assume that the Notes are not redeemed prior to scheduled maturity.

PS-9

PS-10

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE UPON AUTOMATIC CALL

The following examples demonstrate the hypothetical total return upon an Automatic Call under various circumstances. The "total return" as used in these examples is the number, expressed as a percentage, that results from comparing the aggregate payments per $1,000 principal amount Note to $1,000. The hypothetical total returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following tables and examples have been rounded for ease of analysis. The hypothetical examples below do not take into account any tax consequences from investing in the Notes.

Example 1: The Notes are redeemed on the first Call Valuation Date.

Because the Closing Value of each Reference Asset on the first Call Valuation Date is greater than or equal to its Call Value, the Notes are redeemed and you will receive the Redemption Price on the related Call Settlement Date.

The Notes will cease to be outstanding after the Call Settlement Date, and you will not receive any further payments on the Notes.

The total return on investment of the Notes is 3.00%.

Example 2: The Notes are redeemed on the third Call Valuation Date.

** Any Unpaid Coupon Amount has been paid on a previous Contingent Coupon Payment Date.

Because the Closing Value of each Reference Asset on the third Call Valuation Date is greater than or equal to its Call Value, the Notes are redeemed and you will receive the Redemption Price on the related Call Settlement Date.

The Notes will cease to be outstanding after the Call Settlement Date, and you will not receive any further payments on the Notes.

The total return on investment of the Notes is 9.00%.

Example 3: The Notes are redeemed on the final Call Valuation Date.

PS-11

** Assumes NO Contingent Coupons have been previously paid. Accordingly, this amount includes the Contingent Coupon that is payable on this Contingent Coupon Payment Date plus the Unpaid Coupon Amounts that have accrued.

Because the Closing Value of each Reference Asset on the final Call Valuation Date is greater than or equal to its Call Value, the Notes are redeemed and you will receive the Redemption Price on the related Call Settlement Date. Example 3 demonstrates that the Closing Value of at least one Reference Asset is less than its Coupon Barrier Value on each Observation Date prior to the final Call Valuation Date. Accordingly, no Contingent Coupons are payable on the Notes until the final Call Valuation Date.

The Notes will cease to be outstanding after the Call Settlement Date, and you will not receive any further payments on the Notes.

The total return on investment of the Notes is 21.00%.

Each of the examples above demonstrate that the return on the Notes upon an Automatic Call will be limited to the Contingent Coupons, if any, that may be payable on the Notes up to and including the applicable Call Settlement Date.

Each of the examples above demonstrate that the return on your Notes will be limited to the Contingent Coupons and any Unpaid Coupon Amounts that may be payable on the Notes. Each of these examples also demonstrate that, if the Closing Value of any Reference Asset is less than its Coupon Barrier Value on an Observation Date, you will not receive a Contingent Coupon on the related Contingent Coupon Payment Date. If a Contingent Coupon does not become payable with respect to an Observation Date (and instead becomes an Unpaid Coupon Amount), you will receive payment of such amount only if a Contingent Coupon becomes payable with respect to a future Observation Date. If a Contingent Coupon fails to become payable with respect to an Observation Date, and if the Closing Value of any Reference Asset is less than its Coupon Barrier Value on each subsequent Observation Date, you will never receive payment of the Unpaid Coupon Amount(s). If the Closing Value of any Reference Asset is less than its Coupon Barrier Value on each Observation Date, you will not receive any coupon payments during the term of the Notes.

PS-12

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE AT MATURITY

The following table illustrates the hypothetical payment at maturity under various circumstances. The examples set forth below are purely hypothetical and are provided for illustrative purposes only. The numbers appearing in the following tables and examples have been rounded for ease of analysis. The hypothetical examples below do not take into account any tax consequences from investing in the Notes and make the following key assumptions:

* Thehypothetical Initial Values shown above have been chosen for illustrative purposes only and do not represent likely Initial Values. Thehypothetical Coupon Barrier Values, Barrier Values, Physical Delivery Amounts and Fractional Share Amounts shown in the table above are based on such hypothetical Initial Values. The actual Initial Value, Coupon Barrier Value Barrier Value, Physical Delivery Amount and Fractional Share Amount for each Reference Asset are as set forth on the cover of this pricing supplement.

** per $1,000 principal amount Note, excluding the final Contingent Coupon that may be payable on the Maturity Date, and assumes we do not elect to exercise our physical settlement option. For an example demonstrating the amount of shares and cash that you would receive if (a) the Final Value of the Reference Asset is less than the Barrier Value and (b) we elect to exercise our physical settlement option, please see the final example below.

The following examples illustrate how the payments at maturity set forth in the table above are calculated:

PS-13

Example 1: The Final Value of Reference Asset A is $232.50, the Final Value of Reference Asset B is $112.00 and the Final Value of Reference Asset C is $150.00.

Because Reference Asset C has the lowest Reference Asset Return, Reference Asset C is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is greater than or equal to its Barrier Value, you will receive a payment at maturity of $1,000 per $1,000 principal amount Note that you hold (plus (i) any Contingent Coupon that may otherwise be payable on the Maturity Date and (ii) any Unpaid Coupon Amounts that have not previously been paid).

Example 2: The Final Value of Reference Asset A is $142.50, the Final Value of Reference Asset B is $70.00 and the Final Value of Reference Asset C is $90.00.

Because Reference Asset C has the lowest Reference Asset Return, Reference Asset C is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is greater than or equal to its Barrier Value, you will receive a payment at maturity of $1,000 per $1,000 principal amount Note that you hold (plus (i) any Contingent Coupon that may otherwise be payable on the Maturity Date and (ii) any Unpaid Coupon Amounts that have not previously been paid).

Example 3: The Final Value of Reference Asset A is $60.00, the Final Value of Reference Asset B is $31.50 and the Final Value of Reference Asset C is $50.00.

Because Reference Asset A has the lowest Reference Asset Return, Reference Asset A is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is less than its Barrier Value, you will receive a payment at maturity of $400.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × Reference Asset Return of the Least Performing Reference Asset]

$1,000 + [$1,000 × -60.00%] = $400.00

In addition, because the Final Value of at least one Reference Asset is less than its Coupon Barrier Value, you will not receive a Contingent Coupon, nor will you receive any accrued Unpaid Coupon Amounts on the Maturity Date.

Because Reference Asset A is the Least Performing Reference Asset, the Applicable Physical Delivery Amount and the Applicable Fractional Share Amount are 6 shares and 0.66667 shares, respectively, of Reference Asset A. Accordingly, if we do elect to exercise our physical settlement option, you will receive on the Maturity Date a total of 6 shares of Reference Asset A plus $40.00 in cash. For the avoidance of doubt, if the Initial Value of the Least Performing Reference Asset is greater than $1,000 and we do elect to exercise our physical settlement option, you will not receive any shares of such Reference Asset, rather you will only receive a cash payment on the Maturity Date equivalent to the Fractional Share Amount of such Reference Asset multiplied by its Final Value.

Example 3 demonstrates that if the Notes are not redeemed prior to scheduled maturity, and if the Final Value of the Least Performing Reference Asset is less than its Barrier Value, your investment in the Notes will be fully exposed to the decline of the Least Performing Reference Asset from its Initial Value. You will not benefit in any way from the Reference Asset Return of any other Reference Asset being higher than the Reference Asset Return of the Least Performing Reference Asset.

If the Notes are not redeemed prior to scheduled maturity, you may lose up to 100.00% of the principal amount of your Notes. Any payment on the Notes, including the repayment of principal, is subject to the credit risk of Barclays Bank PLC.

PS-14

SELECTED RISK CONSIDERATIONS

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Reference Assets or their components, if any. Some of the risks that apply to an investment in the Notes are summarized below, but we urge you to read the more detailed explanation of risks relating to the Notes generally in the "Risk Factors" section of the prospectus supplement. You should not purchase the Notes unless you understand and can bear the risks of investing in the Notes.

Risks Relating to the Notes Generally

It is impossible to predict what the correlation among the Reference Assets will be over the term of the Notes. The Reference Assets represent different equity markets. These different equity markets may not perform similarly over the term of the Notes.

Although the correlation of the Reference Assets' performance may change over the term of the Notes, the Contingent Coupon rate is determined, in part, based on the correlation of the Reference Assets' performance calculated using our internal models at the time when the terms of the Notes are finalized. A higher Contingent Coupon is generally associated with lower correlation of the Reference Assets, which reflects a greater potential for missed Contingent Coupons and for a loss of principal at maturity.

PS-15

Accordingly, you should understand that a higher coupon payment amount reflects, among other things, an indication of a greater likelihood that you will (a) not receive coupon payments with respect to one or more Observation Dates and/or (b) incur a loss of principal at maturity than would have been the case had the amount of such coupon payments been lower. In addition, actual volatility over the term of the Notes may be significantly higher than the expected volatility at the time the terms of the Notes were determined. If actual volatility is higher than expected, you will face an even greater risk that you will not receive coupon payments and/or that you will lose some or all of your principal at maturity for the reasons described above.

The Redemption Price that you would receive on a Call Settlement Date, together with any coupon payments that you may have received prior to the Call Settlement Date, may be less than the aggregate amount of payments that you would have received had the Notes not been redeemed. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes in a comparable investment with a similar level of risk in the event the Notes are redeemed prior to the Maturity Date. No additional payments will be due after the relevant Call Settlement Date. The fact that the Notes may be redeemed prior to maturity may also adversely impact your ability to sell your Notes and the price at which they may be sold.

Risks Relating to the Issuer

PS-16

Risks Relating to the Reference Assets

Generally, the longer the time remaining to maturity, the more the market price of the Notes will be affected by the factors described above. In addition, each Reference Asset may diverge significantly from the performance of its respective Underlying Index due to differences in trading hours between such Reference Asset and the securities composing its Underlying Index or other circumstances. During periods of market volatility, the component securities held by each Reference Asset may be unavailable in the secondary market, market participants may be unable to calculate accurately the intraday net asset value per share of each Reference Asset and the liquidity of each Reference Asset may be adversely affected. This kind of market volatility may also disrupt the ability of market participants to create and redeem shares in each Reference Asset. Further, market volatility may adversely affect, sometimes materially, the prices at which market participants are willing to buy and sell shares of each Reference Asset. As a result, under these circumstances, the market value of each Reference Asset may vary substantially from the net asset value per share of each Reference Asset. Because the Notes are linked to the performance of each Reference Asset and not its Underlying Index, the return on your Notes may be less than that of an alternative investment linked directly to its Underlying Index.

PS-17

The performance of companies that operate in the semiconductor industry is subject to a number of complex and unpredictable factors such as industry competition, government action and regulation, geopolitical events supply and demand. The values of companies that are involved in the semiconductor industry are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation, changes in the prices and availability of raw materials and competition in the semiconductor industry, both domestically and internationally, including competition from foreign competitors with potentially lower productions costs. Such companies may also be heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, such companies may face competition for the services of, and difficulties in employing and retaining, qualified personnel. Negative developments in the semiconductor industry may have a negative effect on the SOXX Fund and, in turn, may have an adverse effect on the value of the Notes.

The performance of companies that operate in the gold mining industry is subject to a number of complex and unpredictable factors such as industry competition, fluctuations in the market price of gold, government action and regulation, geopolitical events and supply and demand for the products and services offered by such companies. Negative developments in the gold mining industry may have a negative effect on the GDX Fund and, in turn, may have an adverse effect on the value of the Notes.

The oil and gas industry is significantly affected by a number of factors that influence worldwide economic conditions and oil and gas prices, such as natural disasters, supply disruptions, geopolitical events and other factors that may offset or magnify

PS-18

each other, including: worldwide and domestic supplies of, and demand for, crude oil and natural gas; the cost of exploring for, developing, producing, refining and marketing crude oil and natural gas; consumer confidence; changes in weather patterns and climatic changes; the ability of the members of Organization of Petroleum Exporting Countries (OPEC) and other producing nations to agree to and maintain production levels; the worldwide military and political environment, uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities or further acts of terrorism in the United States, or elsewhere; the price and availability of alternative and competing fuels; domestic and foreign governmental regulations and taxes; employment levels and job growth; and general economic conditions worldwide. These or other factors or the absence of such factors could cause a downturn in the oil and natural gas industries generally or regionally and could cause the value of some or all of the securities held by the XOP Fund decline during the term of the Notes. For example, the XOP Fund suffered significant negative performance in 2017 and 2019 while the broader U.S. equities markets achieved positive returns for the same period.

Risks Relating to Conflicts of Interest

In connection with our normal business activities and in connection with hedging our obligations under the Notes, we and our affiliates make markets in and trade various financial instruments or products for our accounts and for the account of our clients and otherwise provide investment banking and other financial services with respect to these financial instruments and products. These financial instruments and products may include securities, derivative instruments or assets that may relate to the Reference Assets or their components, if any. In any such market making, trading and hedging activity, and other financial services, we or our affiliates may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the Notes. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the Notes into account in conducting these activities. Such market making, trading and hedging activity, investment banking and other financial services may negatively impact the value of the Notes.

In addition, the role played by Barclays Capital Inc., as the agent for the Notes, could present significant conflicts of interest with the role of Barclays Bank PLC, as issuer of the Notes. For example, Barclays Capital Inc. or its representatives may derive compensation or financial benefit from the distribution of the Notes and such compensation or financial benefit may serve as incentive to sell the Notes instead of other investments. Furthermore, we and our affiliates establish the offering price of the Notes for initial sale to the public, and the offering price is not based upon any independent verification or valuation.

In addition to the activities described above, we will also act as the Calculation Agent for the Notes. As Calculation Agent, we will determine any values of the Reference Assets and make any other determinations necessary to calculate any payments on the Notes. In making these determinations, the Calculation Agent may be required to make discretionary judgements relating to the Reference Assets, including determining whether a market disruption event has occurred or whether certain adjustments to the Reference Assets or other terms of the Notes are necessary, as further described in the accompanying prospectus supplement. In making these discretionary judgments, our economic interests are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes.

TAX CONSIDERATIONS

You should review carefully the sections in the accompanying prospectus supplement entitled "Material U.S. Federal Income Tax Consequences-Tax Consequences to U.S. Holders-Notes Treated as Prepaid Forward or Derivative Contracts with Associated Contingent Coupons" and, if you are a non-U.S. holder, "-Tax Consequences to Non-U.S. Holders." The following discussion supersedes the discussion in the accompanying prospectus supplement to the extent it is inconsistent therewith. This discussion does not address the U.S. federal income tax consequences of the ownership or disposition of the Reference Asset that you may receive at maturity. You should consult your tax advisor regarding the potential U.S. federal tax consequences of the ownership and disposition of the relevant Reference Asset.

In determining our reporting responsibilities, if any, we intend to treat (i) the Notes for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any Contingent Coupon payments as ordinary income, as described in the section entitled "Material U.S. Federal Income Tax Consequences-Tax Consequences to U.S. Holders-Notes Treated as Prepaid Forward or Derivative Contracts with Associated Contingent Coupons" in the accompanying prospectus supplement. Our special tax counsel, Davis Polk & Wardwell LLP, has advised that it believes this treatment to be reasonable, but that there are other reasonable treatments that the Internal Revenue Service (the "IRS") or a court may adopt.

Sale, exchange or redemption of a Note. Assuming the treatment described above is respected, and except as described below, upon a sale or exchange of the Notes (including redemption for cash upon an automatic call or at maturity), you should recognize capital gain or loss equal to the difference between the amount realized on the sale or exchange and your tax basis in the Notes, which should equal the amount you paid to acquire the Notes (assuming Contingent Coupon payments are properly treated as ordinary income, consistent with the position referred to above). This gain or loss should be short-term capital gain or loss unless you hold the Notes for more than one year, in which case the gain or loss should be long-term capital gain or loss, whether or not you are an initial purchaser of the Notes at the issue price. The deductibility of capital losses is subject to limitations. If you sell your Notes between the time your right to a Contingent Coupon payment is fixed and the time it is paid, it is likely that you will be treated as receiving ordinary income equal to the Contingent Coupon payment. Although uncertain, it is possible that proceeds received from the sale or exchange of your Notes prior to an Observation Date but that can be attributed to an expected Contingent Coupon payment could be treated as ordinary income. You should consult your tax advisor regarding this issue.

If you receive shares of a Reference Asset upon the maturity of your Notes, you should be deemed to have applied the purchase price of your Notes toward the purchase of the shares of the Reference Asset you receive. You should not recognize gain or loss with respect to the shares of the Reference Asset you receive. Instead, assuming Contingent Coupon payments are properly treated as ordinary income, consistent with the position described above, your basis in the shares (including any fractional share) should equal the price you paid to acquire your Notes, and that basis should be allocated proportionately among the shares. Your holding period for the Reference Asset should begin on the day after receipt. With respect to any cash received in lieu of a fractional share of the Reference Asset, you should recognize capital gain or loss in an amount equal to the difference between the amount of the cash received and the tax basis allocable to the fractional share.

As noted above, there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the Notes could be materially affected. In addition, in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of "prepaid forward contracts" and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments and the relevance of factors such as the nature of the underlying property to which the instruments are linked. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially affect the tax consequences of an investment in the Notes, possibly with retroactive effect. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the Notes, including possible alternative treatments and the issues presented by this notice.

Non-U.S. holders. Insofar as we have responsibility as a withholding agent, we do not currently intend to treat Contingent Coupon payments to non-U.S. holders (as defined in the accompanying prospectus supplement) as subject to U.S. withholding tax. However, non-U.S. holders should in any event expect to be required to provide appropriate Forms W-8 or other documentation in order to establish an exemption from backup withholding, as described under the heading "-Information Reporting and Backup Withholding" in the accompanying prospectus supplement. If any withholding is required, we will not be required to pay any additional amounts with respect to amounts withheld.

Treasury regulations under Section 871(m) generally impose a withholding tax on certain "dividend equivalents" under certain "equity linked instruments." A recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2027 that do not have a "delta of one" with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an "Underlying Security"). Based on our determination that the Notes do not have a "delta of one" within the meaning of the regulations, we expect that these regulations will not apply to the Notes with regard to non-U.S. holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. If necessary, further information regarding the potential application of Section 871(m) will be provided in the pricing supplement for the Notes. You should consult your tax advisor regarding the potential application of Section 871(m) to the Notes.

SUPPLEMENTAL PLAN OF DISTRIBUTION

We will agree to sell to Barclays Capital Inc. (the "Agent"), and the Agent will agree to purchase from us, the principal amount of the Notes, and at the price, specified on the cover of this pricing supplement. The Agent will commit to take and pay for all of the Notes, if any are taken.

We expect that delivery of the Notes will be made against payment for the Notes on the Issue Date, which is more than one business day following the Initial Valuation Date. Notwithstanding anything to the contrary in the accompanying prospectus supplement, under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to one business day before delivery will be required to specify alternative settlement arrangements to prevent a failed settlement and should consult their own advisor.
