All Payments on the Securities Based on the Worst Performing of the Russell 2000® Index, the Nasdaq-100 Index® and the S&P 500® Index

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The securities offered are unsecured obligations of Morgan Stanley Finance LLC ("MSFL") and are fully and unconditionally guaranteed by Morgan Stanley. The securities have the terms described in the accompanying product supplement, index supplement and prospectus, as supplemented or modified by this document. The securities do not guarantee the repayment of any principal. Instead, the securities offer the opportunity for investors to earn a fixed monthly coupon at an annual rate of at least 7.90% (to be determined on the pricing date). In addition, the securities will be automatically redeemed if the index closing value of each of the Russell 2000® Index, the Nasdaq-100 Index® and the S&P 500® Index is greater than or equal to its respective initial index value on any monthly redemption determination date (beginning after six months) for the early redemption payment equal to the sum of the stated principal amount plus the related monthly coupon. At maturity, if the securities have not previously been redeemed and the final index value of each underlying index is greater than or equal to 70% of the respective initial index value, which we refer to as the respective downside threshold level, the payment at maturity will be the stated principal amount and the related monthly coupon. If, however, the final index value of any underlying index is less than its respective downside threshold level, investors will be fully exposed to the decline in the worst performing underlying index on a 1-to-1 basis and will receive a payment at maturity that is less than 70% of the stated principal amount of the securities and could be zero. Accordingly, investors could lose their entire initial investment in the securities. The securities are for investors who are willing to risk their principal based on the worst performing of three underlying indices and who seek to earn interest at a potentially above-market rate in exchange for the risk of losing a significant portion or all of their investment, and the possibility of an automatic early redemption prior to maturity. Investors will not participate in any appreciation of any underlying index. The securities are notes issued as part of MSFL's Series A Global Medium-Term Notes program.

All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These securities are not secured obligations and you will not have any security interest in, or otherwise have any access to, any underlying reference asset or assets.

Unless the securities have been previously redeemed, a fixed coupon at an annual rate of at least 7.90% (corresponding to approximately $6.583 per month per security, to be determined on the pricing date) will be paid on each coupon payment date.

Payment at maturity:

If the securities have not been automatically redeemed prior to maturity, the payment at maturity will be determined as follows:

If the final index value of each underlying index is greater than or equal to its respective downside threshold level, investors will receive the stated principal amount plus the monthly coupon for the final interest period.

If the final index value of any underlying index is less than its respective downside threshold level, investors will receive (i) the monthly coupon for the final interest period plus (ii) the product of (a) the stated principal amount and (b) the index performance factor of the worst performing underlying index.

Automatic early redemption (beginning after six months):

If the index closing value of each underlying index is greater than or equal to its initial index value on any monthly redemption determination date, beginning on May 21, 2025 (approximately six months after the original issue date), the securities will be automatically redeemed for an early redemption payment equal to the stated principal amount plus the monthly coupon for the related interest period.

Payment at maturity:

If the securities have not been automatically redeemed prior to maturity, the payment at maturity will be determined as follows:

If the final index value of each underlying index is greater than or equal to its respective downside threshold level, investors will receive the stated principal amount plus the monthly coupon for the final interest period.

Principal at Risk Securities

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000. We estimate that the value of each security on the pricing date will be approximately $985.50, or within $35.00 of that estimate. Our estimate of the value of the securities as determined on the pricing date will be set forth in the final pricing supplement.

What goes into the estimated value on the pricing date?

In valuing the securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlying indices. The estimated value of the securities is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying indices, instruments based on the underlying indices, volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.

What determines the economic terms of the securities?

In determining the economic terms of the securities, including the monthly coupon rate and the downside threshold levels, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the securities would be more favorable to you.

What is the relationship between the estimated value on the pricing date and the secondary market price of the securities?

The price at which MS & Co. purchases the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bid-offer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 5 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, and to our secondary market credit spreads, it would do so based on values higher than the estimated value. We expect that those higher values will also be reflected in your brokerage account statements.

MS & Co. may, but is not obligated to, make a market in the securities, and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

The securities offer investors an opportunity to earn a fixed monthly coupon at an annual rate of at least 7.90% (to be determined on the pricing date). The securities have been designed for investors who are willing to risk their principal and seek to earn interest at a potentially above-market rate in exchange for the risk of losing a significant portion or all of their investment, and the possibility of an automatic early redemption.

The following scenarios are for illustrative purposes only to demonstrate how the early redemption payment or the payment at maturity (if the securities have not previously been redeemed) is calculated, and do not attempt to demonstrate every situation that may occur. Accordingly, the securities may or may not be redeemed, and the payment at maturity may be less than 70% of the stated principal amount of the securities and may be zero.

Scenario 1: The securities are redeemed prior to maturity

Starting after six months, when each underlying index closes at or above its respective initial index value on a monthly redemption determination date, the securities will be automatically redeemed for the stated principal amount plus the monthly coupon for the related monthly interest period. No further payments will be made on the securities once they have been redeemed. Investors will not participate in any appreciation of any underlying index.

Scenario 2: The securities are not redeemed prior to maturity, and investors receive principal back at maturity

This scenario assumes that each underlying index closes below its respective initial index value on every monthly redemption determination date. Consequently, the securities are not automatically redeemed.

On the final observation date, each underlying index closes at or above its respective downside threshold level. At maturity, investors will receive the stated principal amount plus the monthly coupon for the final interest period. Investors will not participate in any appreciation of any underlying index.

Scenario 3: The securities are not redeemed prior to maturity, and investors suffer a substantial loss of principal at maturity

This scenario assumes that each underlying index closes below its respective initial index value on every monthly redemption determination date. Consequently, the securities are not automatically redeemed.

On the final observation date, one or more underlying indices close below the respective downside threshold level(s). At maturity, investors will receive (i) the monthly coupon for the final interest period plus (ii) the product of (a) the stated principal amount and (b) the index performance factor of the worst performing underlying index. Under these circumstances, the payment at maturity will be less than 70% of the stated principal amount and could be zero.

Hypothetical Examples

The following hypothetical examples illustrate how to determine whether the securities are redeemed early and the payment at maturity, if any, if the securities have not been automatically redeemed early. The following examples are for illustrative purposes only. Whether the securities are redeemed early will be determined by reference to the index closing value of each underlying index on each monthly redemption determination date (beginning after six months), and the payment at maturity, if any, will be determined by reference to the final index value of each underlying index on the final observation date. The actual initial index value and downside threshold level for each underlying index will be determined on the pricing date. All payments on the securities, if any, are subject to our credit risk. The numbers in the hypothetical examples below may have been rounded for the ease of analysis. The below examples are based on the following terms:

Hypothetical Monthly Coupon:

7.90% per annum (corresponding to approximately $6.583 per month per security1)

Automatic Early Redemption (starting after six months):

If the index closing value of each underlying index is greater than or equal to its respective initial index value on any monthly redemption determination date, the securities will be automatically redeemed for an early redemption payment equal to the stated principal amount plus the monthly coupon for the related monthly interest period.

Payment at Maturity (if the securities have not been automatically redeemed early):

If the final index value of each underlying index is greater than or equal to its respective downside threshold level, investors will receive the stated principal amount plus the monthly coupon for the final interest period.

If the final index value of any underlying index is less than its respective downside threshold level, investors will receive (i) the monthly coupon for the final interest period plus (ii) the product of (a) the stated principal amount and (b) the index performance factor of the worst performing underlying index. Under these circumstances, the payment at maturity will be less than 70% of the stated principal amount of the securities and could be zero.

Stated Principal Amount:

$1,000 per security

Hypothetical Initial Index Value:

With respect to the RTY Index: 1,200

With respect to the NDX Index: 7,600

With respect to the SPX Index: 3,000

Hypothetical Downside Threshold Level:

With respect to the RTY Index: 840, which is 70% of the hypothetical initial index value for such index

With respect to the NDX Index: 5,320, which is 70% of the hypothetical initial index value for such index

With respect to the SPX Index: 2,100, which is 70% of the hypothetical initial index value for such index

1 The actual monthly coupon will be an amount determined by the calculation agent based on the actual monthly coupon rate and the number of days in the applicable payment period, calculated on a 30/360 day-count basis. The hypothetical monthly coupon of $6.583 is used in these examples for ease of analysis.

How to determine whether the securities are redeemed early:

Index Closing Value

Early Redemption Payment*

RTY Index

NDX Index

SPX Index

Hypothetical Redemption Determination Date 1

1,750 (at or above the initial index value)

8,800 (at or above the initial index value)

2,700 (below the initial index value)

N/A

Hypothetical Redemption Determination Date 2

1,400 (at or above the initial index value)

8,000 (at or above the initial index value)

3,200 (at or above the initial index value)

$1,006.583 (the stated principal amount plus the monthly coupon for the related monthly interest period)

* The Early Redemption Payment includes the unpaid monthly coupon for the related monthly interest period.

If, on any redemption determination date, the index closing value of each underlying index is greater than or equal to its respective initial index value, the securities will be automatically redeemed for an early redemption payment.

On hypothetical redemption determination date 1, the RTY Index and the NDX Index each close at or above the respective initial index value but the SPX Index closes below its initial index value. Therefore, the securities are not redeemed early following such redemption determination date.

On hypothetical redemption determination date 2, each underlying index closes at or above its respective initial index value. Accordingly, the securities are automatically redeemed following such redemption determination date. You receive the early redemption payment, calculated as follows:

stated principal amount + monthly coupon = $1,000 + $6.583 = $1,006.583

No further payments will be made on the securities once they have been redeemed. Additionally, investors will not participate in any appreciation of any underlying index.

The securities will not be redeemed early if the index closing value of any underlying index on the related redemption determination date is less than the initial index value for such underlying index.

How to calculate the payment at maturity (if the securities have not been automatically redeemed):

The examples below illustrate how to calculate the payment at maturity if the securities have not been automatically redeemed prior to maturity.

Final Index Value

Payment at Maturity

(in addition to the monthly coupon of $6.583 for the final interest period)

RTY Index

NDX Index

SPX Index

Example 1:

540 (below the downside threshold level)

3,600 (below the downside threshold level)

2,500 (at or above the downside threshold level)

$1,000 × index performance factor of the worst performing underlying index =
$1,000 × (540 / 1,200) = $450

Example 2:

1,200 (at or above the downside threshold level)

5,600 (at or above the downside threshold level)

1,200 (below the downside threshold level)

$1,000 × (1,200 / 3,000) = $400

Example 3:

540 (below the downside threshold level)

3,040 (below the downside threshold level)

900 (below the downside threshold level)

$1,000 × (900 / 3,000) = $300

Example 4:

360 (below the downside threshold level)

3,040 (below the downside threshold level)

1,200 (below the downside threshold level)

$1,000 × (360 / 1,200) = $300

Example 5:

1,300 (at or above the downside threshold level)

8,000 (at or above the downside threshold level)

3,300 (at or above the downside threshold level)

The stated principal amount

In examples 1 and 2, the final index value(s) of one or two of the underlying indices are at or above the respective downside threshold level(s), but the final index value(s) of one or both of the other underlying indices are below the respective downside threshold level(s). Therefore, investors are exposed to the downside performance of the worst performing underlying index at maturity and receive at maturity, in addition to the monthly coupon for the final interest period, an amount equal to the stated principal amount multiplied by the index performance factor of the worst performing underlying index.

Similarly, in examples 3 and 4, the final index value of each underlying index is below its respective downside threshold level, and investors receive at maturity, in addition to the monthly coupon for the final interest period, an amount equal to the stated principal amount times the index performance factor of the worst performing underlying index. In example 3, the RTY Index has declined 55% from its initial index value to its final index value, the NDX Index has declined 60% from its initial index value to its final index value and the SPX Index has declined 70% from its initial index value to its final index value. Therefore, the payment at maturity equals, in addition to the monthly coupon for the final interest period, the stated principal amount multiplied by the index performance factor of the SPX Index, which is the worst performing underlying index in this example. In example 4, the RTY Index has declined 70% from its initial index value to its final index value, the NDX Index has declined 60% from its initial index value to its final index value and the SPX Index has declined 60% from its initial index value. Therefore, the payment at maturity equals, in addition to the monthly coupon for the final interest period, the stated principal amount times the index performance factor of the RTY Index, which is the worst performing underlying index in this example.

In example 5, the final index value of each underlying index is at or above its respective downside threshold level. Therefore, investors receive at maturity the stated principal amount of the securities plus the monthly coupon for the final interest period. However, investors do not participate in any appreciation of the underlying indices.

If the final index value of ANY underlying index is below its respective downside threshold level, you will be exposed to the downside performance of the worst performing underlying index at maturity, and your payment at maturity will be less than $700 per security and could be zero.

Risk Factors

This section describes the material risks relating to the securities. For further discussion of these and other risks, you should read the section entitled "Risk Factors" in the accompanying product supplement, index supplement and prospectus. We also urge you to consult with your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

Risks Relating to an Investment in the Securities

■The securities do not guarantee the return of any principal. The terms of the securities differ from those of ordinary debt securities in that they do not guarantee the repayment of any principal. If the securities have not been automatically redeemed prior to maturity, and if the final index value of any underlying index is less than its respective downside threshold level of 70% of its initial index value, you will be exposed to the decline in the index closing value of the worst performing underlying index, as compared to its initial index value, on a 1-to-1 basis, and you will receive for each security that you hold at maturity an amount equal to the stated principal amount multiplied by the index performance factor of the worst performing underlying index. In this case, the payment at maturity will be less than 70% of the stated principal amount and could be zero. You could lose a significant portion or all of your investment in the securities.

■Investors will not participate in any appreciation in any underlying index. Investors will not participate in any appreciation in any underlying index from the initial index value for such index, and the return on the securities will be limited to the monthly coupon that is paid for each monthly interest period until early redemption or maturity.

■The market price will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market. We expect that generally the level of interest rates available in the market and the value of each underlying index on any day, including in relation to its respective downside threshold level and initial index value, will affect the value of the securities more than any other factors. Other factors that may influence the value of the securities include:

othe volatility (frequency and magnitude of changes in value) of the underlying indices,

ogeopolitical conditions and economic, financial, political, regulatory or judicial events that affect the component stocks of the underlying indices or securities markets generally and which may affect the value of each underlying index,

odividend rates on the securities underlying the underlying indices,

othe time remaining until the securities mature,

ointerest and yield rates in the market,

othe availability of comparable instruments,

othe composition of the underlying indices and changes in the constituent stocks of such indices, and

oany actual or anticipated changes in our credit ratings or credit spreads.

Some or all of these factors will influence the price that you will receive if you sell your securities prior to maturity. In particular, if any underlying index has closed near or below its respective downside threshold level, the market value of the securities is expected to decrease substantially, and you may have to sell your securities at a substantial discount from the stated principal amount of $1,000 per security.

You cannot predict the future performance of any underlying index based on its historical performance. The value of any underlying index may decrease and be below the respective downside threshold level(s) on the final observation date so that you will lose more than 30% or all of your initial investment in the securities. There can be no assurance that the index closing value of each underlying index will be at or above its respective downside threshold level on the

final observation date so that you do not suffer a significant loss on your initial investment in the securities. See "Russell 2000® Index Overview," "Nasdaq-100 Index® Overview" and "S&P 500® Index Overview" below.

■The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities. You are dependent on our ability to pay all amounts due on the securities on each coupon payment date, upon early redemption and at maturity and therefore you are subject to our credit risk. The securities are not guaranteed by any other entity. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities prior to maturity will be affected by changes in the market's view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the securities.

■As a finance subsidiary, MSFL has no independent operations and will have no independent assets. As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank pari passu with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated pari passu with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanley-issued securities.

■Not equivalent to investing in the underlying indices. Investing in the securities is not equivalent to investing in any underlying index or the component stocks of any underlying index. Investors in the securities will not participate in any positive performance of any underlying index, and will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to stocks that constitute any underlying index.

■Reinvestment risk. The term of your investment in the securities may be shortened due to the automatic early redemption feature of the securities. If the securities are redeemed prior to maturity, you will receive no more monthly coupons and may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns. However, under no circumstances will the securities be redeemed in the first six months of the term of the securities.

■The securities will not be listed on any securities exchange and secondary trading may be limited. Accordingly, you should be willing to hold your securities for the entire 1-year term of the securities. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. MS & Co. may, but is not obligated to, make a market in the securities and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the securities, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

■The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to

Fixed Income Auto-Callable Securities due December 1, 2025, with 6-Month Initial Non-Call Period

Principal at Risk Securities

purchase the securities in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedging-related costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bid-offer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.

The inclusion of the costs of issuing, selling, structuring and hedging the securities in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the securities less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 5 months following the issue date, to the extent that MS & Co. may buy or sell the securities in the secondary market, absent changes in market conditions, including those related to the underlying indices, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.

■The estimated value of the securities is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those generated by others, including other dealers in the market, if they attempted to value the securities. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your securities in the secondary market (if any exists) at any time. The value of your securities at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also "The market price will be influenced by many unpredictable factors" above.

■Hedging and trading activity by our affiliates could potentially affect the value of the securities. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the securities (and to other instruments linked to the underlying indices or their component stocks), including trading in the stocks that constitute the underlying indices as well as in other instruments related to the underlying indices. As a result, these entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final observation date approaches. Some of our affiliates also trade the stocks that constitute the underlying indices and other financial instruments related to the underlying indices on a regular basis as part of their general broker-dealer and other businesses. Any of these hedging or trading activities on or prior to the pricing date could potentially increase the initial index value of an underlying index, and, therefore, could increase (i) the level at or above which such underlying index must close on any redemption determination date so that the securities are redeemed prior to maturity for the early redemption payment (depending also on the performance of the other underlying indices) and (ii) the level at or above which such underlying index must close on the final observation date so that you are not exposed to the negative performance of the worst performing underlying index at maturity (depending also on the performance of the other underlying indices). Additionally, such hedging or trading activities during the term of the securities could affect the value of an underlying index on the redemption determination dates and the final observation date and, accordingly, whether we redeem the securities prior to maturity and the amount of cash you receive at maturity, if any (depending also on the performance of the other underlying indices).

■The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities. As calculation agent, MS & Co. will determine the initial index value and the downside threshold level for each underlying index, whether the securities will be redeemed on any early redemption date and the payment at maturity, if any. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or non-occurrence of market disruption events and the selection of a successor index or calculation of

the index closing value in the event of a market disruption event or discontinuance of an underlying index. These potentially subjective determinations may adversely affect the payout to you at maturity, if any. For further information regarding these types of determinations, see "Description of Auto-Callable Securities-Postponement of Determination Dates," "-Alternate Exchange Calculation in Case of an Event of Default," "-Discontinuance of Any Underlying Index; Alteration of Method of Calculation" and "-Calculation Agent and Calculations" in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

■The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority as to the proper treatment of the securities for U.S. federal income tax purposes, and, therefore, significant aspects of the tax treatment of the securities are uncertain.

Please read the discussion under "Additional Information―Tax considerations" in this document concerning the U.S. federal income tax consequences of an investment in the securities. We intend to treat a security for U.S. federal income tax purposes as a unit consisting of (i) a Put Right (as defined below under "Additional Information―Tax considerations") written by you to us that, if exercised, requires you to pay to us an amount equal to the Deposit (as defined below under "Additional Information―Tax considerations"), in exchange for a cash amount based on the performance of the worst performing underlying index, and (ii) a Deposit with us of a fixed amount of cash to secure your obligation under the Put Right. Alternative U.S. federal income tax treatments of the securities are possible, and if the Internal Revenue Service (the "IRS") were successful in asserting such an alternative tax treatment for the securities the timing and the character of income on the securities might differ significantly from the tax treatment described herein. For example, there is a substantial risk that the IRS could seek to treat the securities as debt instruments subject to Treasury regulations governing contingent payment debt instruments. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the securities, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features. We do not plan to request a ruling from the IRS regarding the tax treatment of the securities, and the IRS or a court may not agree with the tax treatment described herein.

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. While it is not clear whether the securities would be viewed as similar to the prepaid forward contracts described in the notice, it is possible that any Treasury regulations or other guidance issued after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect. The notice focuses on a number of issues, the most relevant of which for holders of the securities are the character and timing of income or loss (including whether the entire coupon on the securities should be required to be included currently as ordinary income) and the degree, if any, to which income realized by non-U.S. investors should be subject to withholding tax.

Non-U.S. Holders should note that we currently do not intend to withhold on any payments made with respect to the securities to Non-U.S. Holders (subject to compliance by such holders with certification necessary to establish an exemption from withholding and to the discussion under "Additional Information―Tax considerations-FATCA"). However, in the event of a change of law or any formal or informal guidance by the IRS, the U.S. Treasury Department or Congress, we may decide to withhold on payments made with respect to the securities to Non-U.S. Holders and will not be required to pay any additional amounts with respect to amounts withheld.

Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, the issues presented by the IRS notice and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Risks Relating to the Underlying Indices

■You are exposed to the price risk of each underlying index with respect to the payment at maturity, if any. Your return on the securities is not linked to a basket consisting of the underlying indices. Rather, it will be contingent upon the independent performance of each underlying index. Unlike an instrument with a return linked to a basket of underlying assets, in which risk is mitigated and diversified among all the components of the basket, you will be

Fixed Income Auto-Callable Securities due December 1, 2025, with 6-Month Initial Non-Call Period

All Payments on the Securities Based on the Worst Performing of the Russell 2000® Index, the Nasdaq-100 Index® and the S&P 500® Index

Principal at Risk Securities

exposed to the risks related to each underlying index. Poor performance by any underlying index over the term of the securities will negatively affect your return and will not be offset or mitigated by any positive performance by the other underlying indices. If any underlying index has declined to below its respective downside threshold level as of the final observation date, you will be fully exposed to the decline in the worst performing underlying index over the term of the securities on a 1-to-1 basis, even if one or both of the other underlying indices have appreciated or have not declined as much. Under this scenario, the value of any such payment will be less than 70% of the stated principal amount and could be zero. Accordingly, your investment is subject to the price risk of each underlying index.

■Because the securities are linked to the performance of the worst performing underlying index, you are exposed to greater risks of sustaining a significant loss on your investment than if the securities were linked to just one index. The risk that you will suffer a significant loss on your investment is greater if you invest in the securities as opposed to substantially similar securities that are linked to the performance of just one underlying index. With three underlying indices, it is more likely that any underlying index will close below its downside threshold level on the final observation date than if the securities were linked to only one underlying index. Therefore, it is more likely that you will suffer a significant loss on your investment. In addition, because each underlying index must close above its initial index value on a monthly redemption determination date (beginning after six months) in order for the securities to be called prior to maturity, the securities are less likely to be called on any early redemption date than if the securities were linked to just one underlying index.

■The securities are linked to the Russell 2000® Index and are subject to risks associated with small-capitalization companies. As the Russell 2000® Index is one of the underlying indices, and the Russell 2000® Index consists of stocks issued by companies with relatively small market capitalization, the securities are linked to the value of small-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the Russell 2000® Index may be more volatile than indices that consist of stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded. In addition, small capitalization companies are typically less well-established and less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than large-capitalization companies and are more susceptible to adverse developments related to their products.

■Adjustments to the underlying indices could adversely affect the value of the securities. The publisher of each underlying index may add, delete or substitute the component stocks of such underlying index or make other methodological changes that could change the value of such underlying index. Any of these actions could adversely affect the value of the securities. The publisher of each underlying index may also discontinue or suspend calculation or publication of such underlying index at any time. In these circumstances, MS & Co., as the calculation agent, will have the sole discretion to substitute a successor index that is comparable to the discontinued index. MS & Co. could have an economic interest that is different than that of investors in the securities insofar as, for example, MS & Co. is permitted to consider indices that are calculated and published by MS & Co. or any of its affiliates. If MS & Co. determines that there is no appropriate successor index on any observation date, the determination of whether the securities will be redeemed and/or the amount payable at maturity, if any, will be based on the value of such underlying index, based on the closing prices of the stocks constituting such underlying index at the time of such discontinuance, without rebalancing or substitution, computed by MS & Co. as calculation agent in accordance with the formula for calculating such underlying index last in effect prior to such discontinuance, as compared to the relevant initial index value or downside threshold level, as applicable (depending also on the performance of the other underlying indices).

S&P 500® Index Overview

The S&P 500® Index, which is calculated, maintained and published by S&P® Dow Jones Indices LLC ("S&P®"), is intended to provide a benchmark for performance measurement of the large capitalization segment of the U.S. equity markets by tracking the stock price movement of 500 companies with large market capitalizations. Component stocks of the S&P 500® Index are required to have a total company level market capitalization that reflects approximately the 85th percentile of the S&P® Total Market Index. The S&P 500® Index measures the relative performance of the common stocks of 500 companies as of a particular time as compared to the performance of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. For additional information about the S&P 500® Index, see the information set forth under "S&P® U.S. Indices-S&P 500® Index" in the accompanying index supplement.

Tax considerations:

Prospective investors should note that the discussion under the section called "United States Federal Taxation" in the accompanying product supplement does not apply to the securities issued under this document and is superseded by the following discussion.

The following is a general discussion of the material U.S. federal income tax consequences and certain estate tax consequences of ownership and disposition of the securities. This discussion applies only to initial investors in the securities who:

•purchase the securities at their "issue price," which will equal the first price at which a substantial amount of the securities is sold to the public (not including bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers); and

•hold the securities as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code").

This discussion does not describe all of the tax consequences that may be relevant to a holder in light of the holder's particular circumstances or to holders subject to special rules, such as:

•certain financial institutions;

•insurance companies;

•dealers and certain traders in securities or commodities;

•investors holding the securities as part of a "straddle," wash sale, conversion transaction, integrated transaction or constructive sale transaction;

•U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

•partnerships or other entities classified as partnerships for U.S. federal income tax purposes;

•regulated investment companies;

•real estate investment trusts; or

•tax-exempt entities, including "individual retirement accounts" or "Roth IRAs" as defined in Section 408 or 408A of the Code, respectively.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds the securities, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partnership holding the securities or a partner in such a partnership, you should consult your tax adviser as to the particular U.S. federal tax consequences of holding and disposing of the securities to you.

As the law applicable to the U.S. federal income taxation of instruments such as the securities is technical and complex, the discussion below necessarily represents only a general summary. The effect of any applicable state, local or non-U.S. tax laws is not discussed, nor are any alternative minimum tax consequences or consequences resulting from the Medicare tax on investment income. Moreover, the discussion below does not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b) of the Code.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof, changes to any of which subsequent to the date hereof may affect the tax consequences described herein. Persons considering the purchase of the securities should consult their tax advisers with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

General

Due to the lack of any controlling legal authority, there is substantial uncertainty regarding the U.S. federal income tax consequences of an investment in the securities. We intend to treat a security, under current law, for U.S. federal income tax purposes, as a unit consisting of the following:

(i) a put right (the "Put Right") written by you to us that, if exercised, requires you to pay us an amount equal to the Deposit (as defined below) in exchange for a cash amount based on the performance of the worst performing underlying index; and

(ii) a deposit with us of a fixed amount of cash, equal to the issue price, to secure your obligation under the Put Right (the "Deposit") that pays interest based on our cost of borrowing at the time of issuance (the "Yield on the Deposit").

Based on the treatment set forth above, a portion of the coupon on the securities will be treated as the Yield on the Deposit, and the remainder will be attributable to the premium on the Put Right (the "Put Premium"). The Yield on the Deposit will be determined by us as of the pricing date and set forth in the applicable pricing supplement.

We will allocate 100% of the issue price of the securities to the Deposit and none to the Put Right. Our allocation of the issue price between the Put Right and the Deposit will be binding on you, unless you timely and explicitly disclose to the Internal Revenue Service (the "IRS") that your allocation is different from ours. This allocation is not, however, binding on the IRS or a court.

No statutory, judicial or administrative authority directly addresses the treatment of the securities or instruments similar to the securities for U.S. federal income tax purposes, and no ruling is being requested from the IRS with respect to the securities. Significant aspects of the U.S. federal income tax consequences of an investment in the securities are uncertain, and no assurance can be given that the IRS or a court will agree with the tax treatment described herein. In the opinion of our counsel, Davis Polk & Wardwell LLP, the treatment of the securities described above is reasonable under current law; however, our counsel has advised us that it is unable to conclude affirmatively that this treatment is more likely than not to be upheld, and that alternative treatments are possible. Moreover, our counsel's opinion is based on market conditions as of the date of this preliminary pricing supplement and is subject to confirmation on the pricing date. Accordingly, you should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the securities (including alternative treatments of the securities). Unless otherwise stated, the following discussion is based on the treatment and the allocation described above.

Tax Consequences to U.S. Holders

This section applies to you only if you are a U.S. Holder. As used herein, the term "U.S. Holder" means a beneficial owner of a security that is, for U.S. federal income tax purposes:

•a citizen or individual resident of the United States;

•a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state thereof or the District of Columbia; or

•an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

Tax Treatment of the Securities

Assuming the treatment of the securities and allocation of the issue price as set forth above are respected, the following U.S. federal income tax consequences should result.

Coupon Payments on the Securities. Under the characterization described above under "-General," only a portion of the coupon payments on the securities will be attributable to the Yield on the Deposit. The remainder of the coupon payments will represent payments attributable to the Put Premium. To the extent attributable to the Yield on the Deposit, coupon

All Payments on the Securities Based on the Worst Performing of the Russell 2000® Index, the Nasdaq-100 Index® and the S&P 500® Index

Principal at Risk Securities

payments on the securities should generally be taxable to a U.S. Holder as ordinary interest income at the time accrued or received, in accordance with the U.S. Holder's method of accounting for U.S. federal income tax purposes.

The Put Premium will not be taxable to a U.S. Holder upon receipt but will be accounted for as described below.

Tax Basis. Based on our determination set forth above, the U.S. Holder's initial tax basis in the Deposit will be 100% of the issue price. The determination of gain or loss with respect to the Put Right is described below.

Receipt of Stated Principal Amount in Cash upon Settlement of the Securities. If a U.S. Holder receives the stated principal amount of a security in cash (excluding cash attributable to coupon payments on the security, which would be taxed as described above under "-Coupon Payments on the Securities"), the Put Right will be deemed to have expired unexercised. In such case, the U.S. Holder will not recognize any gain upon the return of the Deposit, but will recognize the total amount of Put Premium received by the U.S. Holder over the term of the securities (including Put Premium received upon settlement) as short-term capital gain at such time.

Receipt of a Cash Amount Based on the Performance of the Worst Performing Underlying Index upon Maturity of the Securities. If a U.S. Holder receives an amount of cash (excluding cash attributable to coupon payments on the securities, which would be taxed as described above under "-Coupon Payments on the Securities") that is less than the stated principal amount of the securities, the Put Right will be deemed to have been exercised and the U.S. Holder will be deemed to have applied the Deposit toward the cash settlement of the Put Right. In such case, the U.S. Holder will not recognize any gain or loss in respect of the Deposit, but will recognize short-term capital gain or loss in an amount equal to the difference between (i) the amount of cash received by the U.S. Holder at maturity (excluding cash attributable to coupon payments on the securities), plus the total Put Premium received by the U.S. Holder over the term of the securities (including the Put Premium received at maturity) and (ii) the Deposit.

Sale or Exchange of the Securities Prior to Settlement. Upon the sale or exchange of a security, a U.S. Holder will generally recognize long-term capital gain or loss with respect to the Deposit if the U.S. Holder has held the securities for more than one year at the time of such sale or exchange and short-term capital gain or loss otherwise. The U.S. Holder will also generally recognize short-term capital gain or loss with respect to the Put Right. For the purpose of determining such gain or loss, a U.S. Holder should apportion the amount realized on the sale or exchange of a security (excluding any amount attributable to accrued but unpaid Yield on the Deposit, which would be taxed as described under "-Coupon Payments on the Securities") between the Deposit and the Put Right based on their respective values on the date of such sale or exchange. The amount of capital gain or loss on the Deposit will equal the amount realized that is attributable to the Deposit, less the U.S. Holder's adjusted tax basis in the Deposit. The amount realized that is attributable to the Put Right, together with the total Put Premium received by the U.S. Holder over the term of the security, will be treated as short-term capital gain.

If the value of the Deposit on the date of such sale or exchange exceeds the total amount realized on the sale or exchange of the security, the U.S. Holder will be treated as having (i) sold or exchanged the Deposit for an amount equal to its value on that date and (ii) made a payment (the "Put Right Assumption Payment") to the purchaser of the security equal to the amount of such excess, in exchange for the purchaser's assumption of the U.S. Holder's rights and obligations under the Put Right. In such a case, the U.S. Holder will recognize short-term capital gain or loss in respect of the Put Right in an amount equal to the total Put Premium received by the U.S. Holder over the term of the security, less the amount of the Put Right Assumption Payment deemed to be made by the U.S. Holder.

Possible Alternative Tax Treatments of an Investment in the Securities

Due to the absence of authorities that directly address the proper characterization of the securities, no assurance can be given that the IRS will accept, or that a court will uphold, the

Principal at Risk Securities

treatment described above. In particular, there is a substantial risk that the IRS could seek to treat a security or the Deposit as a debt instrument subject to Treasury regulations governing contingent payment debt instruments (the "Contingent Debt Regulations").

If the IRS were successful in asserting that the Contingent Debt Regulations applied to the securities or to the Deposit, the timing and character of income thereon would be significantly affected. Among other things, a U.S. Holder would be required to accrue interest income as original issue discount, subject to adjustments, at a "comparable yield" based on our cost of borrowing. Furthermore, if the securities or Deposit were treated as contingent payment debt instruments, any gain realized with respect to the securities or the Deposit would generally be treated as ordinary income. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the securities, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features.

Even if the Contingent Debt Regulations do not apply to the securities, other alternative U.S. federal income tax characterizations or treatments of the securities are also possible, which if applied could significantly affect the timing and character of the income or loss with respect to the securities. It is possible, for example, that a security could be treated as constituting an "open transaction" with the result that the coupon payments on the securities might not be accounted for separately as giving rise to income to U.S. Holders until the sale, exchange or settlement of the securities. Alternatively, the entire coupon on the securities could be required to be included in income by a U.S. Holder at the time received or accrued. Other alternative characterizations are also possible. Accordingly, prospective purchasers should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities.

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. While it is not clear whether the securities would be viewed as similar to the prepaid forward contracts described in the notice, it is possible that 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. The notice focuses on a number of issues, the most relevant of which for U.S. Holders of the securities is the character and timing of income or loss realized with respect to these instruments (including whether the Put Premium might be required to be included currently as ordinary income). Accordingly, prospective investors should consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including the possible implications of this notice.

Backup Withholding and Information Reporting

Backup withholding may apply in respect of payments on the securities and the payment of proceeds from a sale, exchange or other disposition of the securities, unless a U.S. Holder provides proof of an applicable exemption or a correct taxpayer identification number, and otherwise complies with applicable requirements of the backup withholding rules. The amounts withheld under the backup withholding rules are not an additional tax and may be refunded, or credited against the U.S. Holder's U.S. federal income tax liability, provided that the required information is timely furnished to the IRS. In addition, information returns will be filed with the IRS in connection with payments on the securities and the payment of proceeds from a sale, exchange or other disposition of the securities, unless the U.S. Holder provides proof of an applicable exemption from the information reporting rules.

Tax Consequences to Non-U.S. Holders

This section applies to you only if you are a Non-U.S. Holder. As used herein, the term "Non-U.S. Holder" means a beneficial owner of a security that is, for U.S. federal income tax purposes:

•an individual who is classified as a nonresident alien;

•a foreign corporation; or

•a foreign trust or estate.

Principal at Risk Securities

The term "Non-U.S. Holder" does not include any of the following holders:

•a holder who is an individual present in the United States for 183 days or more in the taxable year of disposition and who is not otherwise a resident of the United States for U.S. federal income tax purposes;

•certain former citizens or residents of the United States; or

•a holder for whom income or gain in respect of the securities is effectively connected with the conduct of a trade or business in the United States.

Such holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities.

General

Assuming the treatment of the securities as set forth above is respected and subject to the discussions below regarding the potential application of Section 871(m) of the Code and FATCA, payments with respect to a security, and gain realized on the sale, exchange or other disposition of such security, should not be subject to U.S. federal income or withholding tax under current law, provided that:

•the Non-U.S. Holder does not own, directly or by attribution, ten percent or more of the total combined voting power of all classes of our stock entitled to vote;

•the Non-U.S. Holder is not a controlled foreign corporation related, directly or indirectly, to us through stock ownership;

•the Non-U.S. Holder is not a bank receiving interest under Section 881(c)(3)(A) of the Code; and

•the certification requirement described below has been fulfilled with respect to the beneficial owner.

Certification Requirement. The certification requirement referred to in the preceding paragraph will be fulfilled if the beneficial owner of a security (or a financial institution holding a security on behalf of the beneficial owner) furnishes to the applicable withholding agent an IRS Form W-8BEN (or other appropriate form), on which the beneficial owner certifies under penalties of perjury that it is not a U.S. person.

Possible Alternative Tax Treatments of an Investment in the Securities

As described above under "-Tax Consequences to U.S. Holders-Possible Alternative Tax Treatments of an Investment in the Securities," the IRS may seek to apply a different characterization and tax treatment from the treatment described herein. While the U.S. federal income and withholding tax consequences to a Non-U.S. Holder of ownership and disposition of a security under current law should generally be the same as those described immediately above, it is possible that a Non-U.S. Holder could be subject to withholding tax under certain recharacterizations of the securities.

Moreover, among the issues addressed in the IRS notice described in "-Tax Consequences to U.S. Holders" is the degree, if any, to which income realized by Non-U.S. Holders should be subject to withholding tax. It is possible that any Treasury regulations or other guidance issued after consideration of this issue could materially and adversely affect the withholding tax consequences of ownership and disposition of the securities, possibly with retroactive effect. Accordingly, prospective investors should consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the securities, including the possible implications of the notice discussed above. Prospective investors should note that we currently do not intend to withhold on any of the payments made with respect to the securities to Non-U.S. Holders (subject to compliance by such holders with the certification requirement described above and to the discussion below regarding FATCA). However, in the event of a change of law or any formal or informal guidance by the IRS, the U.S. Treasury Department or Congress, we (or any financial intermediary) may decide to withhold on payments made with respect to the securities to Non-U.S. Holders and we will not be required

to pay any additional amounts with respect to amounts withheld.

Section 871(m) Withholding Tax on Dividend Equivalents

Section 871(m) of the Code and Treasury regulations promulgated thereunder ("Section 871(m)") generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an "Underlying Security"). Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the applicable Treasury regulations (a "Specified Security"). However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2027 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the securities and current market conditions, we expect that the securities will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final pricing supplement. Assuming that the securities do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the securities should not be Specified Securities and, therefore, should not be subject to Section 871(m).

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 Section 871(m) withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

U.S. Federal Estate Tax

Individual Non-U.S. Holders and entities the property of which is potentially includible in such an individual's gross estate for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty exemption, the securities may be treated as U.S. situs property subject to U.S. federal estate tax. Prospective investors that are non-U.S. individuals, or are entities of the type described above, should consult their tax advisers regarding the U.S. federal estate tax consequences of an investment in the securities.

Backup Withholding and Information Reporting

Information returns will be filed with the IRS in connection with any coupon payment and may be filed with the IRS in connection with the payment at maturity on the securities and the payment of proceeds from a sale, exchange or other disposition of the securities. A Non-U.S. Holder may be subject to backup withholding in respect of amounts paid to the Non-U.S. Holder, unless such Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person for U.S. federal income tax purposes or otherwise establishes an exemption. Compliance with the certification procedures described under "-General-Certification Requirement" will satisfy the certification requirements necessary to avoid backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder's U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

FATCA

Legislation commonly referred to as "FATCA" generally imposes a withholding tax of 30% on payments to certain non-U.S. entities (including financial intermediaries) with respect to certain financial instruments, unless various U.S. information reporting and due diligence requirements have been satisfied. An intergovernmental agreement between the United States and the non-U.S. entity's jurisdiction may modify these requirements. FATCA generally applies to certain financial instruments that are treated as paying U.S.-source interest or other U.S.-source "fixed or determinable annual or periodical" income ("FDAP income"). Withholding (if

applicable) applies to payments of U.S.-source FDAP income and to payments of gross proceeds of the disposition (including upon retirement) of certain financial instruments treated as providing for U.S.-source interest or dividends. Under proposed regulations (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization), no withholding will apply on payments of gross proceeds (other than amounts treated as interest or other FDAP income). While the treatment of the securities is unclear, you should assume that the yield on the Deposit will be subject to the FATCA rules. It is also possible in light of this uncertainty that an applicable withholding agent will treat the entire amount of the coupon payments as being subject to the FATCA rules. If withholding applies to the securities, we will not be required to pay any additional amounts with respect to amounts withheld. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the potential application of FATCA to the securities.

The discussion in the preceding paragraphs, insofar as it purports to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitutes the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the securities.

Use of proceeds and hedging:

The proceeds from the sale of the securities will be used by us for general corporate purposes. We will receive, in aggregate, $1,000 per security issued, because, when we enter into hedging transactions in order to meet our obligations under the securities, our hedging counterparty will reimburse the cost of the agent's commissions. The costs of the securities borne by you and described beginning on page 4 above comprise the agent's commissions and the cost of issuing, structuring and hedging the securities.

On or prior to the pricing date, we expect to hedge our anticipated exposure in connection with the securities by entering into hedging transactions with our affiliates and/or third-party dealers. We expect our hedging counterparties to take positions in the stocks constituting the underlying indices, in futures and/or options contracts on the underlying indices or the component stocks of the underlying indices listed on major securities markets, or positions in any other available securities or instruments that they may wish to use in connection with such hedging. Such purchase activity could potentially increase the initial index value of an underlying index, and, as a result, could increase (i) the level at or above which such underlying index must close on any redemption determination date so that the securities are redeemed prior to maturity for the early redemption payment (depending also on the performance of the other underlying indices) and (ii) the level at or above which such underlying index must close on the final observation date so that you are not exposed to the negative performance of the worst performing underlying index at maturity (depending also on the performance of the other underlying indices). These entities may be unwinding or adjusting hedge positions during the term of the securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final observation date approaches. Additionally, our hedging activities, as well as our other trading activities, during the term of the securities could potentially affect the value of an underlying index on the redemption determination dates and the final observation date and, accordingly, whether we redeem the securities prior to maturity and the amount of cash you receive at maturity, if any (depending also on the performance of the other underlying indices).

Additional considerations:

Client accounts over which Morgan Stanley, Morgan Stanley Wealth Management or any of their respective subsidiaries have investment discretion are not permitted to purchase the securities, either directly or indirectly.
