Summary

The RBS Annual Reset Coupon Notes with Fixed Buffer Linked to the S&P 500® Index due June   , 2014 (together with the related guarantees, each, a “security” and collectively, the “securities”) are senior unsecured obligations issued by us, The Royal Bank of Scotland plc, and are fully and unconditionally guaranteed by our parent company, The Royal Bank of Scotland Group plc.  The securities will rank equally with all of our senior unsecured indebtedness from time to time outstanding, and any payments due on the securities, including any coupon payments or repayment of your investment, will be subject to the ability of RBS, as the issuer of the securities, and RBSG, as the guarantor of the issuer’s obligations under the securities, to pay their respective obligations as they become due.

The securities provide investors with annual Coupon Payments which amount will depend on the performance of the S&P 500® Index (the “Underlying Equity Index”) during each individual Observation Period.  An investor’s return on the securities, if any, will be limited to the Coupon Payments, which will never exceed the Maximum Annual Coupon.  Investors will receive a Payment at Maturity equal to the Original Offering Price, only if the Final Value of the Underlying Equity Index does not decrease below the Buffer Value.  If the Final Value of the Underlying Equity Index decreases below the Buffer Value, investors will be exposed to any such decrease below the Buffer Value on a one-for-one basis. Investors must be willing to accept the risk of losing some or a significant portion of their investment.

Hypothetical Coupon Payment and Payment at Maturity Profiles

The potential return or loss on an investment in the securities will be based on the sum of (i) the total amount of Coupon Payments that you may receive over the term of the securities and (ii) the Payment at Maturity on the maturity date.  For purposes of illustration only, the following tables and graph reflect (i) the hypothetical Coupon Payments per security for a range of hypothetical Annual Returns for the Observation Periods over the term of the securities and (ii) the hypothetical Payment at Maturity per security for a range of hypothetical Final Values of the S&P 500® Index from +70% to -70%.  Because the S&P 500® Index is a price return index, the Final Values presented below will not include any income generated by dividends paid on the stocks included in the S&P 500® Index, which you would otherwise be entitled to receive if you invested in those stocks directly.

The illustrations below reflect the Minimum Annual Coupon of 2.00% per annum, the Maximum Annual Coupon of 5.05% per annum, the Buffer Amount of 20%, the hypothetical Initial Value of 1286.17 (the closing level of the Underlying Equity Index on June 6, 2011) and the hypothetical Buffer Value of 1028.94 (80% of the hypothetical Initial Value, rounded to two decimal places). The actual Coupon Rates for any given Observation Period and the actual Coupon Payments payable on the securities will depend on the actual Starting Annual Values and the actual Ending Annual Values for such Observation Period.  The actual Payment at Maturity that you are entitled to receive will depend on the actual Initial Value and Buffer Value, which will be determined on the pricing date and set forth in the final pricing supplement, and the actual Final Value, which will be determined on the Valuation Date.

Any payment on the securities (including the coupon payments and the payment at maturity) is subject to the ability of RBS, as the issuer of the securities, and RBSG, as the guarantor of the issuer’s obligations under the securities, to pay their respective obligations as they become due.

	HYPOTHETICAL COUPON PAYMENTS PER SECURITY(1)
Hypothetical Annual Return Scenarios	First Observation Period	Second Observation Period	Third Observation Period	Total Coupon Payments
If the Annual Return is less than 0% for each Observation Period:	$20.00	$20.00	$20.00	$60.00
If the Annual Return is greater than or equal to 0% for the first Observation Period and less than 0% for all subsequent Observation Periods:	$50.50	$20.00	$20.00	$90.50
If the Annual Return is greater than or equal to 0% for the first two Observation Periods and less than 0% for the final Observation Period:	$50.50	$50.50	$20.00	$121.00
If the Annual Return is greater than or equal to 0% for each Observation Period:	$50.50	$50.50	$50.50	$151.50(2)

(1) If the Annual Return for an Observation Period is less than 0%, then the Coupon Rate for such Observation Period will be the Minimum Annual Coupon.  If the Annual Return for an Observation Period is greater than or equal to 0%, then the Coupon Rate for such Observation Period will be the Maximum Annual Coupon.

(2) The maximum total return on your investment in the securities will never exceed 15.15% over the full term of the securities (or 5.05% per annum) regardless of the performance of the Underlying Equity Index during the term of the securities.

Hypothetical Total Payment Profile

The potential return or loss on an investment in the securities will be based on the sum of (i) the total amount of Coupon Payments that you may receive over the term of the securities and (ii) the Payment at Maturity on the maturity date.  For purposes of illustration only, the table below illustrates the total payments on the securities for a range of hypothetical scenarios, reflecting the following values and hypothetical data:

·   the Buffer Amount of 20% (representing a protection against any decrease in the level of the Underlying Equity Index up to the Buffer Value);

·   the hypothetical Initial Value of 1286.17 (the closing level of the Underlying Equity Index on June 6, 2011); and

·   the hypothetical Buffer Value of 1028.94 (80% of the hypothetical Initial Value, rounded to two decimal places).

Any payment at maturity is subject to the ability of RBS, as the issuer of the securities, and RBSG, as the guarantor of the issuer’s obligations under the securities, to pay their respective obligations as they become due.

(1)   The total Coupon Payments per security will depend on the Annual Return for each Observation Period over the 3-year term of the securities.  The total Coupon Payments per security can range from a minimum of $60.00 (if the Annual Return is less than 0% for each Observation Period) to a maximum of $151.50 (if the Annual Return is greater than or equal to 0% for each Observation Period).  For purposes of illustration, the above table shows a few examples of hypothetical total Coupon Payments over the 3-year term of the securities, assuming a range of Annual Return scenarios.  The actual Coupon Payments payable on the securities will depend on the actual Annual Return for each Observation Period.

(2)   We have assumed for purposes of this illustration that the Annual Return is greater than or equal to 0% for all three Observation Periods, resulting in total Coupon Payments per security over the 3-year term of the securities of $151.50.  See Example 6 on page PS-7.

(3)   We have assumed for purposes of this illustration that the Annual Return is greater than or equal to 0% for two Observation Periods, and less than 0% for one Observation Period, resulting in total Coupon Payments per security over the 3-year term of the securities of $121.00.  See Example 5 on page PS-7.

(4)   We have assumed for purposes of this illustration that the Annual Return is greater than or equal to 0% for one Observation Period, and less than 0% for two Observation Periods, resulting in total Coupon Payments per security over the 3-year term of the securities of $90.50.  See Example 3 on page PS-6 and Example 4 on page PS-7.

(5)   If the hypothetical Final Value is less than the hypothetical Initial Value, we have assumed for purposes of illustration that the Annual Return is less than 0% for each of the three Observation Periods, resulting in total Coupon Payments per security over the 3-year term of the securities of $60.00.  See Example 1 and Example 2 on page PS-6.

Examples of Coupon Payment and Payment at Maturity Calculations

For each of the examples below:

·   If the Annual Return is less than 0% for an Observation Period (i.e., the Ending Annual Value is less than the Starting Annual Value for such Observation Period), the Coupon Rate for such Observation Period will be equal to the Minimum Annual Coupon of 2.00% per annum, and the Coupon Payment for such Observation Period will equal $20.00 per security; and

·   If the Annual Return is greater than or equal to 0% for an Observation Period (i.e., the Ending Annual Value is greater than or equal to the Starting Annual Value for such Observation Period), the Coupon Rate for such Observation Period will be equal to the Maximum Annual Coupon of 5.05% per annum, and the Coupon Payment for such Observation Period will equal $50.50 per security.

EXAMPLE 1 — The hypothetical Annual Return is less than 0% for each Observation Period.  In addition, the hypothetical Final Value is 771.70 (which is 40% below the hypothetical Initial Value), representing a decrease in the level of the Underlying Equity Index from the Initial Value by more than the Buffer Amount:

Total Coupon Payments over the term of the security:

$20.00 + $20.00 + $20.00 = $60.00

Reference Return	=	771.70 – 1286.17	=	-40%
		1286.17

Payment at Maturity (per security) = $1,000 + [$1,000 x (-40% + 20%)] = $800

Total payments over the term of the securities:

Total Coupon Payments + Payment at Maturity	=	$60.00 + $800.00
	=	$860.00 per security (i.e., a 14.00% loss over the 3-year term of the securities)

If the level of the Underlying Equity Index has decreased from the Initial Value to the Final Value by a percentage that is greater than the Buffer Amount (i.e., if the Final Value is less than the Buffer Value), your investment will be fully exposed to any decline of the Underlying Equity Index beyond the Buffer Amount, and you could lose some or a significant portion (up to 80% of the Original Offering Price) of your investment.  The annual Coupon Payments may not be sufficient to offset such loss.

EXAMPLE 2 — The hypothetical Annual Return is less than 0% for each Observation Period.  In addition, the hypothetical Final Value is 1028.94 (which is 20% below the hypothetical Initial Value), representing a decrease in the level of the Underlying Equity Index from the Initial Value by a percentage that is not greater than the Buffer Amount:

Total Coupon Payments over the term of the security:

$20.00 + $20.00 + $20.00 = $60.00

Payment at Maturity (per security) = $1,000

Total payments over the term of the securities:

Total Coupon Payments + Payment at Maturity	=	$60.00 + $1,000.00
	=	$1,060.00 per security (i.e., a 6.00% return over the 3-year term of the securities)

If the level of the Underlying Equity Index has decreased from the Initial Value to the Final Value by a percentage that is not greater than the Buffer Amount (i.e., if the Final Value is less than the Initial Value, but is equal to or greater than the Buffer Value), the Payment at Maturity will equal the $1,000 Original Offering Price and your return on the securities will be limited to the Coupon Payments.

EXAMPLE 3 — The hypothetical Annual Return is greater than or equal to 0% for one Observation Period and less than 0% for two Observation Periods.  In addition, the hypothetical Final Value is 1414.79 (which is 10% above the hypothetical Initial Value):

Total Coupon Payments over the term of the security:

$50.50 + $20.00 + $20.00 = $90.50

Payment at Maturity (per security) = $1,000

Total payments over the term of the securities:

Total Coupon Payments + Payment at Maturity	=	$90.50 + $1,000.00
	=	$1,090.50 per security (i.e., a 9.50% return over the 3-year term of the securities)

If the level of the Underlying Equity Index has increased from the Initial Value to the Final Value, the Payment at Maturity will equal the $1,000 Original Offering Price.  In no event will the Payment at Maturity exceed the Original Offering Price regardless of how well the Underlying Equity Index performs.  Your return on the securities, if any, will depend solely on the Coupon Payments.

EXAMPLE 4 — The hypothetical Annual Return is greater than or equal to 0% for one Observation Period and less than 0% for two Observation Periods.  In addition, the hypothetical Final Value is 1543.40 (which is 20% above the hypothetical Initial Value):

Total Coupon Payments over the term of the security:

$50.50 + $20.00 + $20.00 = $90.50

Payment at Maturity (per security) = $1,000

Total payments over the term of the securities:

Total Coupon Payments + Payment at Maturity	=	$90.50 + $1,000.00
	=	$1,090.50 per security (i.e., a 9.05% return over the 3-year term of the securities)

If the level of the Underlying Equity Index has increased from the Initial Value to the Final Value, the Payment at Maturity will equal the $1,000 Original Offering Price.  In no event will the Payment at Maturity exceed the Original Offering Price regardless of how well the Underlying Equity Index performs.  Your return on the securities, if any, will depend solely on the Coupon Payments.

EXAMPLE 5 — The hypothetical Annual Return is greater than or equal to 0% for two Observation Periods and less than 0% for one Observation Period.  In addition, the hypothetical Final Value is 1800.64 (which is 40% above the hypothetical Initial Value):

Total Coupon Payments over the term of the security:

$50.50 + $50.50 + $20.00 = $121.00

Payment at Maturity (per security) = $1,000

Total payments over the term of the securities:

Total Coupon Payments + Payment at Maturity	=	$121.00 + $1,000.00
	=	$1,121.00 per security (i.e., a 12.10% return over the 3-year term of the securities)

If the level of the Underlying Equity Index has increased from the Initial Value to the Final Value, the Payment at Maturity will equal the $1,000 Original Offering Price.  In no event will the Payment at Maturity exceed the Original Offering Price regardless of how well the Underlying Equity Index performs.  Your return on the securities, if any, will depend solely on the Coupon Payments.

EXAMPLE 6 — The hypothetical Annual Return is greater than or equal to 0% for all three Observation Periods.  In addition, the hypothetical Final Value is 1929.26 (which is 50% above the hypothetical Initial Value):

Total Coupon Payments over the term of the security:

$50.50 + $50.50 + $50.50 = $151.50

Payment at Maturity (per security) = $1,000

Total payments over the term of the securities:

Total Coupon Payments + Payment at Maturity	=	$151.50 + $1,000.00
	=	$1,151.50 per security (i.e., a 15.15% return over the 3-year term of the securities)

If the level of the Underlying Equity Index has increased from the Initial Value to the Final Value, the Payment at Maturity will equal the $1,000 Original Offering Price.  In no event will the Payment at Maturity exceed the Original Offering Price regardless of how well the Underlying Equity Index performs.  Your return on the securities, if any, will depend solely on the Coupon Payments.

Risk Factors

There are important differences between the securities and a conventional debt security.  An investment in the securities involves significant risks, including those listed below.  You should carefully review the more detailed explanation of risks relating to the securities in the “Risk Factors” sections beginning on page S-15 of the product supplement.  We also urge you to consult with your investment, legal, accounting, tax, and other advisors before you invest in the securities.

·   The securities are not conventional debt securities.  You may lose some or a significant portion of your investment in the securities.

·   The credit risk of The Royal Bank of Scotland plc and The Royal Bank of Scotland Group plc, and their credit ratings and credit spreads may adversely affect the value of the securities.

·   Your return on the securities is entirely dependent on the performance of the Underlying Equity Index during each Observation Period.

·   You may receive below-market Coupon Payments in respect of one or more Observation Periods.

·   You may receive only a limited amount of Coupon Payments in respect of one or more Observation Periods.

·   The return on your initial investment is limited to the annual Coupon Payments, which will never exceed the Maximum Annual Coupon.

·   The Payment at Maturity will not exceed the Original Offering Price regardless of how well the Underlying Equity Index performs from the Initial Value to the Final Value.

·   The Payment at Maturity will depend on the Final Value, which is determined only on a valuation date shortly before the maturity date, and will not depend on the performance of the Underlying Equity Index during any one or more individual Observation Periods.

·   The securities may not be a suitable investment for you.

·   Although we are a bank, the securities are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation, the Deposit Insurance Fund or any other government agency.

Investor Considerations

You may wish to consider an investment in the securities if:

·   You anticipate that the level of the Underlying Equity Index will increase moderately from the Starting Annual Value to the Ending Annual Value during the Observation Periods.

·   You accept that your investment may result in a loss, which could be significant, if the Final Value of the Underlying Equity Index is less than the Initial Value by an amount that exceeds the Buffer Amount.

·   You accept that the return on the securities will not exceed the Maximum Annual Coupon during the term of the securities and that the Payment at Maturity will not exceed the Original Offering Price.

·   You are willing to forgo market rates of interest on the securities such as fixed or floating rate interest paid on conventional interest bearing debt securities.

·   You seek exposure to the performance of the Underlying Equity Index with no expectation of dividends or other benefits of owning the securities comprising the Underlying Equity Index.

·   You are willing to accept that a trading market is not expected to develop for the securities and you understand that secondary market prices for the securities, if any, will be affected by various factors, including our actual and perceived creditworthiness.

·   You are able to and willing to hold the securities until maturity.

·   You are willing to make an investment, the payments on which depend on the creditworthiness of RBS, as the issuer of the securities, and RBSG, as the guarantor of the issuer’s obligations under the securities.

The securities may not be an appropriate investment for you if:

·   You are not willing to be exposed to the performance of the Underlying Equity Index.

·   You seek full principal protection or preservation of capital invested.

·   You believe the level of the Underlying Equity Index will decrease from the Initial Value by an amount that exceeds the Buffer Amount, or that the level of the Underlying Equity Index will not increase sufficiently over the term of the securities to provide you with your desired return.

·   You seek a return on your investment that will not be capped at the Maximum Annual Coupon and a Payment at Maturity that will not be limited to the Original Offering Price.

·   You want to receive dividends or other distributions paid on the securities included in the Underlying Equity Index.

·   You seek assurances that there will be a liquid market if and when you want to sell the securities prior to maturity.

·   You are unwilling or are unable to assume the credit risk associated with RBS, as the issuer, and RBSG, as the guarantor of the issuer’s obligations under the securities.

The Underlying Equity Index

We have derived all information contained in this pricing supplement regarding the S&P 500® Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information.  Such information reflects the policies of, and is subject to change by, Standard & Poor’s Financial Services, LLC (“S&P”).  We make no representation or warranty as to the accuracy or completeness of such information.  The S&P 500® Index was developed by S&P and is calculated, maintained and published by S&P.  S&P has no obligation to continue to publish, and may discontinue the publication of, the S&P 500® Index.

The S&P 500® Index is reported by Bloomberg L.P. under the ticker symbol “SPX.”

The S&P 500® Index is intended to provide a performance benchmark for the U.S. equity markets.  The calculation of the level of the S&P 500® Index (discussed below in further detail) is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 500 companies (the “S&P Component Stocks”) as of a particular time as compared to the aggregate average Market Value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.  Historically, the “Market Value” of any S&P Component Stock was calculated as the product of the market price per share and the number of the then-outstanding shares of such S&P Component Stock.  As discussed below, on March 21, 2005, S&P began to use a new methodology to calculate the Market Value of the S&P Component Stocks and on September 16, 2005, S&P completed its transition to the new calculation methodology.  The 500 companies are not the 500 largest companies listed on the New York Stock Exchange (the “NYSE”) and not all 500 companies are listed on such exchange.  S&P chooses companies for inclusion in the S&P 500® Index with the objective of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the U.S. equity market.  S&P may from time to time, in its sole discretion, add companies to, or delete companies from, the S&P 500® Index to achieve the objectives stated above.  Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the company’s common stock is widely-held and the Market Value and trading activity of the common stock of that company.

On March 21, 2005, S&P began to calculate the S&P 500® Index based on a half float-adjusted formula, and on September 16, 2005, the S&P 500® Index became fully float-adjusted.  S&P’s criteria for selecting stocks for the S&P 500® Index was not changed by the shift to float adjustment.  However, the adjustment affects each company’s weight in the S&P 500® Index (i.e., its Market Value).

Under float adjustment, the share counts used in calculating the S&P 500® Index reflect only those shares that are available to investors, not all of a company’s outstanding shares.  S&P defines three groups of shareholders whose holdings are subject to float adjustment:

·   holdings by other publicly traded corporations, venture capital firms, private equity firms, strategic partners, or leveraged buyout groups;

·   holdings by government entities, including all levels of government in the United States or foreign countries; and

·   holdings by current or former officers and directors of the company, founders of the company or family trusts of officers, directors or founders, as well as holdings of trusts, foundations, pension funds, employee stock ownership plans, or other investment vehicles associated with and controlled by the company.

However, treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock and rights are not part of the float.  In cases where holdings in a group exceed 10% of the outstanding shares of a company, the holdings of that group will be excluded from the float-adjusted count of shares to be used in the S&P 500® Index calculation.  Mutual funds, investment advisory firms, pension funds or foundations not associated with the company and investment funds in insurance companies, shares that trust beneficiaries may buy or sell without difficulty or significant additional expense beyond typical brokerage fees, and, if a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class if such shares are convertible by shareholders without undue delay and cost, are also part of the float.  Shares held in a trust to allow investors in countries outside the country of domicile (e.g., ADRs, CDIs and Canadian exchangeable shares) are normally part of the float.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares, defined as the total shares outstanding less shares held in one or more of the three groups listed above where the group holdings exceed 10% of the outstanding shares, by the total shares outstanding.  (On March 21, 2005, the S&P 500® Index moved halfway to float adjustment, meaning that if a stock has an IWF of 0.80, the IWF used to calculate the S&P 500® Index between March 21, 2005 and September 16, 2005 was 0.90.  On September 16, 2005, S&P began to calculate the S&P 500® Index on a fully float-adjusted basis, meaning that if a stock has an IWF of 0.80, the IWF used to calculate the S&P 500® Index on and after September 16, 2005 is 0.80). The float-adjusted Index is calculated by dividing the sum of the IWF multiplied by both the price and the total shares outstanding for each stock by the Index Divisor.  For companies with multiple classes of stock, S&P calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

As of the date of this pricing supplement, the S&P 500® Index is calculated using a base-weighted aggregate methodology: the level of the S&P 500®Index reflects the total Market Value of all 500 S&P Component Stocks relative to the S&P 500® Index’s base period of 1941–43 (the “Base Period”).

An indexed number is used to represent the results of this calculation in order to make the value easier to work with and track over time.

The actual total Market Value of the S&P Component Stocks during the Base Period has been set equal to an indexed value of 10.  This is often indicated by the notation 1941–43=10.  In practice, the daily calculation of the S&P 500® Index is computed by dividing the total Market Value of the S&P Component Stocks by a number called the Index Divisor.  By itself, the Index Divisor is an arbitrary number.  However, in the context of the calculation of the S&P 500® Index, it is the only link to the original Base Period level of the S&P 500®Index.  The Index Divisor keeps the S&P 500® Index comparable over time and is the manipulation point for all adjustments to the S&P 500®Index (“Index Maintenance”).

Index Maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spin-offs.

To prevent the level of the S&P 500® Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the S&P 500® Index require an Index Divisor adjustment.  By adjusting the Index Divisor for the change in total Market Value, the level of the S&P 500® Index remains constant.  This helps maintain the level of the S&P 500®Index as an accurate barometer of stock market performance and ensures that the movement of the S&P 500® Index does not reflect the corporate actions of individual companies in the S&P 500® Index.  All Index Divisor adjustments are made after the close of trading and after the calculation of the closing level of the S&P 500® Index.  Some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the S&P 500® Index and do not require Index Divisor adjustments.

The table below summarizes the types of Index Maintenance adjustments and indicates whether or not an Index Divisor adjustment is required.

Type of Corporate Action	Comments	Divisor Adjustment
Company added/ deleted	Net change in market value determines divisor adjustment.	Yes
Change in shares outstanding	Any combination of secondary issuance, share repurchase or buy back – share counts revised to reflect change.	Yes
Stock split	Share count revised to reflect new count.  Divisor adjustment is not required since the share count and price changes are offsetting.	No
Spin-off	If the spun-off company is not being added to the index, the divisor adjustment reflects the decline in index market value (i.e., the value of the spun-off unit).	Yes
Spin-off	Spun-off company added to the index, no company removed from index.	No
Spin-off	Spun-off company added to the index, another company removed to keep number of names fixed.  Divisor adjustment reflects deletion.	Yes
Change in IWF due to a corporate action or a purchase or sale by an inside holder.	Increasing (decreasing) the IWF increases (decreases) the total market value of the index.  The divisor change reflects the change in market value caused by the change to an IWF.	Yes
Special dividend	When a company pays a special dividend the share price is assumed to drop by the amount of the dividend; the divisor adjustment reflects this drop in index market value.	Yes
Rights offering	Each shareholder receives the right to buy a proportional number of additional shares at a set (often discounted) price.  The calculation assumes that the offering is fully subscribed.  Divisor adjustment reflects increase in market cap measured as the shares issued multiplied by the price paid.	Yes

Stock splits and stock dividends do not affect the Index Divisor, because following a split or dividend, both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the S&P Component Stock.  All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

Each of the corporate events exemplified in the table requiring an adjustment to the Index Divisor has the effect of altering the Market Value of the S&P Component Stock and consequently of altering the aggregate Market Value of the S&P Component Stocks (the “Post-Event Aggregate Market Value”).  In order that the level of the S&P 500® Index (the “Pre-Event Index Value”) not be affected by the altered Market Value (whether increase or decrease) of the affected Component Stock, a new Index Divisor (“New Divisor”) is derived as follows:

Post-Event Aggregate Market Value	=	Pre-Event Index Value
New Divisor

New Divisor	=	Post-Event Aggregate Market Value
		Pre-Event Index Value

A large part of the Index Maintenance process involves tracking the changes in the number of shares outstanding of each of the S&P 500® Index companies.  Four times a year, on a Friday close to the end of each calendar quarter, the share totals of companies in the S&P 500® Index are updated as required by any changes in the number of shares outstanding.  After the totals are updated, the Index Divisor is adjusted to compensate for the net change in the total Market Value of the S&P 500®Index.  In addition, any changes over 5% in the current common shares outstanding for the S&P 500® Index companies are carefully reviewed on a weekly basis, and when appropriate, an immediate adjustment is made to the Index Divisor.

Summary Tax Consequences

You should review carefully the section in the accompanying product supplement entitled “U.S. Federal Income Tax Consequences.” Although the tax consequences of an investment in the securities are uncertain, we believe it is reasonable to treat the securities for U.S. federal income tax purposes as prepaid financial contracts, with associated Coupon Payments by us to you. Under this treatment:

· we will treat Coupon Payments as ordinary income to you when received or accrued, in accordance with your method of accounting for U.S. federal income tax purposes;

· we will treat Coupon Payments to non-U.S. holders as subject to withholding tax; and

· upon a sale, exchange or retirement of the securities, your gain or loss generally should be capital gain or loss (although the treatment of any sales proceeds attributable to any accrued but unpaid Coupon Payment is unclear) and should be long-term capital gain or loss if you have held the securities for more than one year.

If, however, the Internal Revenue Service (the “IRS”) were successful in asserting an alternative treatment for the securities, the tax consequences of ownership and disposition of the securities might be affected materially and adversely.  We do not plan to request a ruling from the IRS, and the IRS or a court might not agree with the tax treatment described in this pricing supplement and the accompanying product supplement.

 In 2007, Treasury and the IRS released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments, which may include the securities.  The notice focuses in particular on whether to require holders of 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; the relevance of factors such as the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. persons should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” regime, which very generally can operate to recharacterize certain long-term capital gain as ordinary income and impose an interest charge.  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 and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect.

 For a discussion of U.K. tax considerations relating to the securities, you should refer to the section in the accompanying product supplement entitled “Taxation in the United Kingdom.”

 We do not provide any advice on tax matters.  You should consult your tax adviser regarding the U.S. federal tax consequences of an investment in the securities (including possible alternative treatments and the issues presented by the 2007 notice), as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Four Categories of RBS Investor Products

RBS Investor Products is the brand name for RBS’s securities offerings that provide market-driven investment solutions across different asset classes and investor risk profiles to help meet your portfolio needs.  RBS Investor Products are divided into four broad categories depending on the level of risk to your principal invested at maturity:  Protection, Fixed Buffer, Contingent Buffer and Full Exposure.  These broad categories are intended to help you to first understand the degree of your principal at risk at maturity, before you consider the upside potential of RBS Investor Products.  The following description is only an overview of the four categories of RBS Investor Products, and does not represent any particular security nor guarantee performance.  All payments due on RBS Investor Products are subject to the credit risk of RBS, as the issuer, and RBSG, as the guarantor of the issuer’s obligations under the securities.

Protection investments provide for full or partial protection on your invested principal at maturity against downside market movements, subject to the creditworthiness of the issuer and the guarantor.  These securities are designed for investors who place a priority on the preservation of principal at maturity, while potentially offering better returns than traditional fixed income investments.  These securities tend to have a longer term than securities that do not offer protection, and principal invested is not protected prior to maturity.

Fixed Buffer investments provide a modest buffer at maturity against downside market movements.  These securities are designed for investors who seek potential growth or income, and who also seek some cushion against modest market declines up to a specified buffer.  You are exposed to the full market decline in the underlying asset beyond the specified buffer, and you can lose some or a substantial portion of your investment.

Contingent Buffer investments provide some protection against downside market movements only if the underlying asset does not fall to or below a specified level during the term of the securities.  If the underlying asset falls to or below this specified level, you are exposed to the full market decline in the underlying asset at maturity without any cushion against downside market movements.  These investments are for more aggressive investors who can tolerate full downside risk but find the contingent buffer to be an appealing form of tactical cushion.  You can lose some or all of your investment.

Full Exposure investments expose investors to full downside risk to any decline in the underlying asset.  These investments are meant for investors who are willing to take full market risk in return for either enhanced appreciation or access to a unique underlying asset or strategy.  You can lose some or all of your investment.

RBS Investor Products can provide access to a range of asset classes and risk and potential return profiles.  These investments can play an important role as a portion of a diversified investment portfolio.  In assessing the potential return of any RBS Investor Product, you should understand that these securities involve significant investment risks, and you should carefully review the applicable pricing supplement, product supplement and prospectus before investing.
