Call feature:

Beginning on April 7, 2025, an early redemption, in whole but not in part, will occur on a redemption date if and only if the output of a risk neutral valuation model on a business day that is at least 2 but no more than 5 business days prior to such redemption date, as selected by the calculation agent (the "determination date"), taking as input: (i) prevailing reference market levels, volatilities and correlations, as applicable and in each case as of the determination date and (ii) Morgan Stanley's credit spreads as of the pricing date, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. If we call the securities, we will give you notice at least 2 business days before the call date specified in the notice. No further payments will be made on the securities once they have been redeemed.

Monthly coupon:

Unless the securities have been previously redeemed, a fixed coupon at an annual rate of at least 9.40% (corresponding to approximately $7.833 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 previously been redeemed prior to maturity, the payment at maturity will be, in addition to the final monthly coupon, as follows:

If the final index value of each underlying index is greater than or equal to its respective downside threshold level: the stated principal amount.

If the final index value of any underlying index is less than its respective downside threshold level: (i) the stated principal amount multiplied by (ii) 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.

Maturity:

Monthly coupon:

A monthly coupon at an annual rate of at least 9.40% (corresponding to approximately $7.833 per month per security, to be determined on the pricing date) will be paid on the securities on each coupon payment date.

Early redemption:

Beginning on April 7, 2025, we will redeem the securities on any quarterly redemption date for an early redemption payment equal to the stated principal amount plus the monthly coupon for the relevant monthly interest period, if and only if the output of a risk neutral valuation model on a business day that is at least 2 but no more than 5 business days prior to such redemption date, based on the inputs indicated under "Call feature" on the cover page, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. An early redemption of the securities will not automatically occur based on the performance of the underlying indices. In accordance with the risk neutral valuation model determination noted herein, it is more likely that we will redeem the securities when it would otherwise be advantageous for you to continue to hold the securities. As such, we will be more likely to redeem the securities when the monthly coupon payable on the securities is significantly greater than the interest that would be payable on instruments of a comparable maturity and credit rating trading in the market. In other words, we will be more likely to redeem the securities when the securities are paying an above-market coupon. If the securities are redeemed prior to maturity, you will receive no more monthly coupon payments, may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

On the other hand, we will be less likely to redeem the securities when the index closing value of any underlying index is near or below its respective downside threshold level, such that you are likely to suffer a significant loss on your initial investment in the securities at maturity. Therefore, if we do not redeem the securities, it is more likely that you will suffer a significant loss at maturity.

Payment at maturity:

If the securities have not previously been redeemed prior to maturity, the payment at maturity will be, in addition to the final monthly coupon, as follows:

If the final index value of each underlying index is greater than or equal to its respective downside threshold level: the stated principal amount.

If the final index value of any underlying index is less than its respective downside

threshold level: (i) the stated principal amount multiplied by (ii) 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.

Scenario 1: The securities are redeemed prior to maturity.

This scenario assumes that the securities are redeemed prior to the maturity date on one of the quarterly redemption dates, starting on April 7, 2025, based on the output of a risk neutral valuation model, for the redemption payment equal to the stated principal amount plus the related monthly coupon for the related interest period. Prior to the early redemption, investors receive the monthly coupon for each interest period. No further payments will be made on the securities once they have been redeemed. Investors will not participate in any appreciation in any underlying index.

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

This scenario assumes that the securities are not redeemed on any of the quarterly redemption dates, and, as a result, investors hold the securities to maturity. Investors receive the monthly coupon for each interest period. On the final observation date, each underlying index closes at or above its respective downside threshold level. The payment due at maturity will be, in addition to the final monthly coupon, the stated principal amount. Investors will not participate in any appreciation in 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 the securities are not redeemed on any of the quarterly redemption dates, and, as a result, investors hold the securities to maturity. Investors receive the monthly coupon for each interest period. On the final observation date, one or more underlying indices close below the respective downside threshold level(s). At maturity, investors will receive an amount equal to the stated principal amount multiplied by 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.

Call Feature:

Beginning on April 7, 2025, an early redemption, in whole but not in part, will occur on a redemption date if and only if the output of a risk neutral valuation model on a business day that is at least 2 but no more than 5 business days prior to such redemption date, as selected by the calculation agent (the "determination date"), taking as input: (i) prevailing reference market levels, volatilities and correlations, as applicable and in each case as of the determination date and (ii) Morgan Stanley's credit spreads as of the pricing date, indicates that redeeming on such date is economically rational for us as compared to not redeeming on such date. If we call the securities, we will give you notice at least 2 business days before the call date specified in the notice. Any redemption payment will be equal to the stated principal amount plus the related monthly coupon. If the securities are redeemed prior to maturity, you will receive no more monthly coupon payments, may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

Payment at Maturity:

If the securities have not been previously redeemed prior to maturity, the payment at maturity will be, in addition to the final monthly coupon, as follows:

If the final index value of each underlying index is greater than or equal to its respective downside threshold level: the stated principal amount.

If the final index value of any underlying index is less than its respective downside threshold level: (i) the stated principal amount multiplied by (ii) 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.

Calculation agent:

The calculation agent for the securities will be MS & Co. All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will, in the absence of manifest error, be conclusive for all purposes and binding on you, the trustee and us.

All calculations with respect to the monthly coupon, the redemption payment and the payment at maturity, if any, shall be made by the calculation agent and shall be rounded to the nearest one hundred-thousandth, with five one-millionths rounded upward (e.g., .876545 would be rounded to .87655); all dollar amounts related to determination of the amount of cash payable per stated principal amount shall be rounded to the nearest ten-thousandth, with five one hundred-thousandths rounded upward (e.g., .76545 would be rounded up to .7655); and all dollar amounts paid on the aggregate principal amount of the securities shall be rounded to the nearest cent, with one-half cent rounded upward.

Because the calculation agent is our affiliate, the economic interests of the calculation agent and its affiliates may be adverse to your interests as an investor in the securities, including with respect to certain determinations and judgments that the calculation agent must make in determining the payment that you will receive, if any, on each coupon payment date, upon early redemption or at maturity or whether a market disruption event has occurred. See "Market disruption event" and "Discontinuance of an underlying index; alteration of method of calculation" below. MS & Co. is obligated to carry out its duties and functions as calculation agent in good faith and using its reasonable judgment.

Business day:

Any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in The City of New York.

Index business day:

With respect to each underlying index, a day, as determined by the calculation agent, on which trading is generally conducted on each of the relevant exchange(s) for such underlying index, other than a day on which trading on such exchange(s) is scheduled to close prior to the time of the posting of its regular final weekday closing price.

Index closing value:

With respect to the RTY Index, the index closing value on any index business day shall be determined by the calculation agent and shall equal the closing value of the RTY Index, or any successor index (as defined under "Discontinuance of an underlying index; alteration of method of calculation" below), reported by Bloomberg Financial Services, or any successor reporting service the calculation agent may select, on such index business day. In certain circumstances, the index closing value for the RTY Index will be based on the alternate calculation of the RTY Index as described under "Discontinuance of an underlying index; alteration of method of calculation" below.

With respect to each of the SPX Index and the NDXT Index, the index closing value on any index business day shall be determined by the calculation agent and shall equal the official closing value of such underlying index, or any successor index (as defined under "Discontinuance of an underlying index; alteration of method of calculation" below), published at the regular official weekday close of trading on such index business day

by the underlying index publisher for such underlying index. In certain circumstances, the index closing value for the SPX Index or the NDXT Index will be based on the alternate calculation of such underlying index as described under "Discontinuance of an underlying index; alteration of method of calculation" below.

Market disruption event:

With respect to each underlying index, market disruption event means:

(i)the occurrence or existence of any of:

(a) a suspension, absence or material limitation of trading of securities then constituting 20 percent or more of the value of such underlying index (or a successor index) on the relevant exchange(s) for such securities for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such relevant exchange(s), or

(b) a breakdown or failure in the price and trade reporting systems of any relevant exchange as a result of which the reported trading prices for securities then constituting 20 percent or more of the value of such underlying index (or a successor index) during the last one-half hour preceding the close of the principal trading session on such relevant exchange(s) are materially inaccurate, or

(c) the suspension, material limitation or absence of trading on any major U.S. securities market for trading in futures or options contracts or exchange-traded funds related to such underlying index (or a successor index) for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such market,

in each case as determined by the calculation agent in its sole discretion; and

(ii)a determination by the calculation agent in its sole discretion that any event described in clause (i) above materially interfered with our ability or the ability of any of our affiliates to unwind or adjust all or a material portion of the hedge position with respect to the securities.

For the purpose of determining whether a market disruption event exists at any time with respect to an underlying index, if trading in a security included in such underlying index is materially suspended or materially limited at that time, then the relevant percentage contribution of that security to the value of such underlying index shall be based on a comparison of (x) the portion of the value of such underlying index attributable to that security relative to (y) the overall value of such underlying index, in each case immediately before that suspension or limitation.

For the purpose of determining whether a market disruption event exists at any time with respect to an underlying index: (1) a limitation on the hours or number of days of trading will not constitute a market disruption event if it results from an announced change in the regular business hours of the relevant exchange or market, (2) a decision to permanently discontinue trading in the relevant futures or options contract or exchange-traded fund will not constitute a market disruption event, (3) a suspension of trading in futures or options contracts or exchange-traded funds on such underlying index by the primary securities market trading in such contracts or funds by reason of (a) a price change exceeding limits set by such securities exchange or market, (b) an imbalance of orders relating to such contracts or funds or (c) a disparity in bid and ask quotes relating to such contracts or funds will constitute a suspension, absence or material limitation of trading in futures or options contracts or exchange-traded funds related to such underlying index and (4) a "suspension, absence or material limitation of trading" on any relevant exchange or on the primary market on which futures or options contracts or exchange-traded funds related to such underlying index are traded will not include any time when such securities market is itself closed for trading under ordinary circumstances.

Relevant exchange:

With respect to each underlying index or its successor index, the primary exchange(s) or market(s) of trading for (i) any security then included in such index and (ii) any futures or options contracts related to such index or to any security then included in such index.

Postponement of the final observation date:

The final observation date is subject to postponement due to non-index business days or certain market disruption events, as described in the following paragraph.

If a market disruption event with respect to any underlying index occurs on the scheduled final observation date, or if the final observation date is not an index business day with respect to any underlying index, the index closing value solely for such underlying index for such date will be determined on the immediately succeeding index business day on which no market disruption event will have occurred with respect to such affected underlying index; provided that the final index value for any underlying index will not be determined on a date later than the fifth scheduled index business day after the scheduled final observation date, and if such date is not an index business day, or if there is a market disruption event on such date, the calculation agent will determine the index closing value of such underlying index on such date in accordance with the formula for calculating such underlying index last in effect prior to the commencement of the market disruption event (or prior to the non-index business day), without rebalancing or substitution, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate

of the closing price that would have prevailed but for such suspension, limitation or non-index business day) on such date of each security most recently constituting such underlying index.

Postponement of coupon payment dates and the maturity date:

If any scheduled coupon payment date is not a business day, that monthly coupon shall be paid on the next succeeding business day. If, due to a market disruption event or otherwise, the final observation date with respect to any underlying index is postponed so that it falls less than two business days prior to the scheduled maturity date, the maturity date shall be postponed to the second business day following the final observation date as postponed, by which date the index closing value of each underlying index has been determined and no adjustment shall be made to the payment at maturity.

Discontinuance of an underlying index; alteration of method of calculation:

If any underlying index publisher discontinues publication of the relevant underlying index and such underlying index publisher or another entity (including MS & Co.) publishes a successor or substitute index that the calculation agent determines, in its sole discretion, to be comparable to the discontinued index (such index being referred to herein as the "successor index"), then any subsequent index closing value for the discontinued index will be determined by reference to the published value of such successor index at the regular weekday close of trading on any index business day that the index closing value for such underlying index is to be determined, and, to the extent the index closing value of such successor index differs from the index closing value of the relevant underlying index at the time of such substitution, proportionate adjustments shall be made by the calculation agent to the relevant initial index value and downside threshold level.

Upon any selection by the calculation agent of a successor index, the calculation agent will cause written notice thereof to be furnished to the trustee, to us and to the depositary, as holder of the securities, within three business days of such selection. We expect that such notice will be made available to you, as a beneficial owner of the securities, in accordance with the standard rules and procedures of the depositary and its direct and indirect participants.

If any underlying index publisher discontinues publication of the relevant underlying index or a successor index prior to, and such discontinuance is continuing on, the final observation date and the calculation agent determines, in its sole discretion, that no successor index is available at such time, then the calculation agent will determine the index closing value for such underlying index for such date. The index closing value of such underlying index or such successor index will be computed by the calculation agent in accordance with the formula for and method of calculating such index last in effect prior to such discontinuance, using the closing price (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the closing price that would have prevailed but for such suspension or limitation) at the close of the principal trading session of the relevant exchange on such date of each security most recently constituting such index without any rebalancing or substitution of such securities following such discontinuance. Notwithstanding these alternative arrangements, discontinuance of the publication of an underlying index may adversely affect the value of the securities.

If at any time, the method of calculating any underlying index or any successor index, or the value thereof, is changed in a material respect, or if any underlying index or any successor index is in any other way modified so that such index does not, in the opinion of the calculation agent, fairly represent the value of such index had such changes or modifications not been made, then, from and after such time, the calculation agent will, at the close of business in New York City on each date on which the index closing value for such underlying index is to be determined, make such calculations and adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a value of a stock index comparable to such underlying index or such successor index, as the case may be, as if such changes or modifications had not been made, and the calculation agent will calculate the index closing value with reference to such underlying index or such successor index, as adjusted. Accordingly, if the method of calculating any underlying index or any successor index is modified so that the value of such index is a fraction of what it would have been if it had not been modified (e.g., due to a split in such underlying index), then the calculation agent will adjust such index in order to arrive at a value of such underlying index or such successor index as if it had not been modified (e.g., as if such split had not occurred).

Alternate exchange calculation in case of an event of default:

If an event of default with respect to the securities shall have occurred and be continuing, the amount declared due and payable upon any acceleration of the securities (the "Acceleration Amount") will be an amount, determined by the calculation agent in its sole discretion, that is equal to the cost of having a qualified financial institution, of the kind and selected as described below, expressly assume all our payment and other obligations with respect to the securities as of that day and as if no default or acceleration had occurred, or to undertake other obligations providing substantially equivalent economic value to you with respect to the securities. That cost will equal:

●the lowest amount that a qualified financial institution would charge to effect this assumption or undertaking, plus

●the reasonable expenses, including reasonable attorneys' fees, incurred by the holders of the securities in preparing any documentation necessary for this assumption or undertaking.

During the default quotation period for the securities, which we describe below, the holders of the securities and/or we may request a qualified financial institution to provide a quotation of the amount it would charge to effect this assumption or undertaking. If either party obtains a quotation, it must notify the other party in writing of the quotation. The amount referred to in the first bullet point above will equal the lowest-or, if there is only one, the only-quotation obtained, and as to which notice is so given, during the default quotation period. With respect to any quotation, however, the party not obtaining the quotation may object, on reasonable and significant grounds, to the assumption or undertaking by the qualified financial institution providing the quotation and notify the other party in writing of those grounds within two business days after the last day of the default quotation period, in which case that quotation will be disregarded in determining the Acceleration Amount.

Notwithstanding the foregoing, if a voluntary or involuntary liquidation, bankruptcy or insolvency of, or any analogous proceeding is filed with respect to MSFL or Morgan Stanley, then depending on applicable bankruptcy law, your claim may be limited to an amount that could be less than the Acceleration Amount.

If the maturity of the securities is accelerated because of an event of default as described above, we shall, or shall cause the calculation agent to, provide written notice to the trustee at its New York office, on which notice the trustee may conclusively rely, and to the depositary of the Acceleration Amount and the aggregate cash amount due, if any, with respect to the securities as promptly as possible and in no event later than two business days after the date of such acceleration.

Default quotation period

The default quotation period is the period beginning on the day the Acceleration Amount first becomes due and ending on the third business day after that day, unless:

●no quotation of the kind referred to above is obtained, or

●every quotation of that kind obtained is objected to within five business days after the due date as described above.

If either of these two events occurs, the default quotation period will continue until the third business day after the first business day on which prompt notice of a quotation is given as described above. If that quotation is objected to as described above within five business days after that first business day, however, the default quotation period will continue as described in the prior sentence and this sentence.

In any event, if the default quotation period and the subsequent two business day objection period have not ended before the final observation date, then the Acceleration Amount will equal the principal amount of the securities.

Qualified financial institutions

For the purpose of determining the Acceleration Amount at any time, a qualified financial institution must be a financial institution organized under the laws of any jurisdiction in the United States or Europe, which at that time has outstanding debt obligations with a stated maturity of one year or less from the date of issue and rated either:

●A-2 or higher by Standard & Poor's Ratings Services or any successor, or any other comparable rating then used by that rating agency, or

●P-2 or higher by Moody's Investors Service or any successor, or any other comparable rating then used by that rating agency.

Issuer notices to registered security holders, the trustee and the depositary:

In the event that the maturity date is postponed due to postponement of the final observation date, the issuer shall give notice of such postponement and, once it has been determined, of the date to which the maturity date has been rescheduled (i) to each registered holder of the securities by mailing notice of such postponement by first class mail, postage prepaid, to such registered holder's last address as it shall appear upon the registry books, (ii) to the trustee by facsimile, confirmed by mailing such notice to the trustee by first class mail, postage prepaid, at its New York office and (iii) to the depositary by telephone or facsimile confirmed by mailing such notice to the depositary by first class mail, postage prepaid. Any notice that is mailed to a registered holder of the securities in the manner herein provided shall be conclusively presumed to have been duly given to such registered holder, whether or not such registered holder receives the notice. The issuer shall give such notice as promptly as possible, and in no case later than (i) with respect to notice of postponement of the maturity date, the business day immediately preceding the scheduled maturity date, and (ii) with respect to notice of the date to which the maturity date has been rescheduled, the business day immediately following the final observation date as postponed.

The issuer shall, or shall cause the calculation agent to, (i) provide written notice to the trustee, on which notice the trustee may conclusively rely, and to the depositary of the amount of cash to be delivered as

monthly coupon with respect to each security on or prior to 10:30 a.m. (New York City time) on the business day preceding each coupon payment date, and (ii) deliver the aggregate cash amount due with respect to the monthly coupon to the trustee for delivery to the depositary, as holder of the securities, on the applicable coupon payment date.

The issuer shall, or shall cause the calculation agent to, (i) provide written notice to the trustee, on which notice the trustee may conclusively rely, and to the depositary of the amount of cash to be delivered with respect to the securities, on or prior to 10:30 a.m. (New York City time) on the business day preceding the redemption date or the business day preceding the maturity date, as applicable, and (ii) deliver the aggregate cash amount due with respect to the securities to the trustee for delivery to the depositary, as holder of the securities, on the redemption date or maturity date, as applicable.

Book entry security or certificated security:

Book entry. The securities will be issued in the form of one or more fully registered global securities which will be deposited with, or on behalf of, the depositary and will be registered in the name of a nominee of the depositary. The depositary's nominee will be the only registered holder of the securities. Your beneficial interest in the securities will be evidenced solely by entries on the books of the securities intermediary acting on your behalf as a direct or indirect participant in the depositary. In this preliminary pricing supplement, all references to payments or notices to you will mean payments or notices to the depositary, as the registered holder of the securities, for distribution to participants in accordance with the depositary's procedures. For more information regarding the depositary and book entry notes, please read "The Depositary" in the accompanying prospectus supplement and "Forms of Securities-Global Securities-Registered Global Securities" in the accompanying prospectus.

Tax considerations:

Prospective investors should note that the discussion under the section called "United States Federal Taxation" in the accompanying prospectus 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 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 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.

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 5 above comprise the agent's commissions and the cost of issuing, structuring and hedging the securities. See also "Use of Proceeds" in the accompanying prospectus.

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, increase the downside threshold level for such underlying index, which, if the securities are not redeemed prior to maturity, is 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 such underlying index on the final observation date, and, accordingly, 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.

Supplemental information regarding plan of distribution; conflicts of interest:

MS & Co. expects to sell all of the securities that it purchases from us to an unaffiliated dealer at a price of $ per security, for further sale to certain fee-based advisory accounts at the price to public of $1,000 per security. MS & Co. will not receive a sales commission with respect to the securities.

MS & Co. is an affiliate of MSFL and a wholly owned subsidiary of Morgan Stanley, and it and other affiliates of ours expect to make a profit by selling, structuring and, when applicable, hedging the securities. When MS & Co. prices this offering of securities, it will determine the economic terms of the securities, including the monthly coupon rate, such that for each security the estimated value on the pricing date will be no lower than the minimum level described in "Investment Overview" beginning on page 3.

MS & Co. will conduct this offering in compliance with the requirements of FINRA Rule 5121 of the Financial Industry Regulatory Authority, Inc., which is commonly referred to as FINRA, regarding a FINRA member firm's distribution of the securities of an affiliate and related conflicts of interest. MS & Co. or any of our other affiliates may not make sales in this offering to any discretionary account.

In order to facilitate the offering of the securities, the agent may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. Specifically, the agent may sell more securities than it is obligated to purchase in connection with the offering, creating a naked short position in the securities, for its own account. The agent must close out any naked short position by purchasing the securities in the open market. A naked short position is more likely to be created if the agent is concerned that there may be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering. As an additional means of facilitating the offering, the agent may bid for, and purchase, the securities or the securities underlying the underlying indices in the open market to stabilize the price of the securities. Any of these activities may raise or maintain the market price of the securities above independent market levels or prevent or retard a decline in the market price of the securities. The agent is not required to engage in these activities, and may end any of these activities at any time. An affiliate of the agent has entered into a hedging transaction with us in connection with this offering of securities. See "Plan of Distribution (Conflicts of Interest)" in the accompanying prospectus supplement and "Use of Proceeds and Hedging" above.
