The Notes

The notes offered are debt securities of Morgan Stanley. From the original issue date until June 20, 2014, interest on the notes will accrue and be payable on the notes quarterly, in arrears, at 5.00% per annum, and thereafter, during the floating interest rate period, interest on the notes will accrue and be payable on the notes quarterly, in arrears, at a rate equal to 3-Month USD LIBOR plus 3.25%, subject to the minimum interest rate of 4.00% per annum during the floating interest rate period. We describe the basic features of these notes in the sections of the accompanying prospectus called “Description of Debt Securities—Floating Rate Debt Securities” and prospectus supplement called “Description of Notes,” subject to and as modified by the provisions described below. All payments on the notes are subject to the credit risk of Morgan Stanley.

The stated principal amount of each note and the issue price is $1,000. The issue price of the notes includes the agent’s commissions paid with respect to the notes as well as the cost of hedging our obligations under the notes.  The cost of hedging includes the projected profit that our subsidiaries may realize in consideration for assuming the risks inherent in managing the hedging transactions.  The secondary market price, if any, at which MS & Co. is willing to purchase the notes, is expected to be affected adversely by the inclusion of these commissions and hedging costs in the issue price.  In addition, the secondary market price may be lower due to the costs of unwinding the related hedging transactions at the time of the secondary market transaction.  See “Risk Factors—Market Risk—The inclusion of commissions and projected profit from hedging in the original issue price is likely to adversely affect secondary market prices.”

Additional Provisions

Reference Rate

“LIBOR” as defined in the accompanying prospectus in the section called “Description of Debt Securities—Floating Rate Debt Securities” and “—Base Rates” with an index maturity of 3 months and an index currency of U.S. dollars and as displayed on Reuters Page LIBOR01.

Historical Information

The following graph sets forth the historical percentage levels of the reference rate for the period from January 1, 2002 to June 4, 2012.  The historical levels of the reference rate do not reflect the 3.25% spread that will apply to the interest that accrues on the notes for any interest payment period during the floating interest rate period, and should not be taken as an indication of its future performance.  We obtained the information in the graph below from Bloomberg Financial Markets, without independent verification.

* The bold line in the graph above represents the minimum interest rate of 4.00% per annum.

Risk Factors

The notes involve risks not associated with an investment in ordinary floating rate notes. An investment in the notes entails significant risks not associated with similar investments in a conventional debt security, including, but not limited to, fluctuations in the reference rate, and other events that are difficult to predict and beyond the issuer’s control.  This section describes the most significant risks relating to the notes. For a complete list of risk factors, please see the accompanying prospectus supplement and the accompanying prospectus. You should carefully consider whether the notes are suited to your particular circumstances before you decide to purchase them.

Yield Risk

§   The historical performance of the reference rate is not an indication of future performance.The historical performance of the reference rate should not be taken as an indication of future performance during the term of the notes.  Changes in the levels of the reference rate will affect the trading price of the notes, but it is impossible to predict whether such levels will rise or fall.

Issuer Risk

§   Investors 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 notes.  Investors are dependent on our ability to pay all amounts due on the notes on interest payment dates and at maturity and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. The notes are not guaranteed by any other entity.  If we default on our obligations under the notes, your investment would be at risk and you could lose some or all of your investment.  As a result, the market value of the notes 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 value of the notes.

Market Risk

§   The price at which the notes may be sold prior to maturity will depend on a number of factors and may be substantially less than the amount for which they were originally purchased.  Some of these factors include, but are not limited to: (i) actual or anticipated changes in the level of the reference rate, (ii) volatility of the level of the reference rate, (iii) changes in interest and yield rates, (iv) any actual or anticipated changes in our credit ratings or credit spreads and (v) time remaining to maturity.  Depending on the actual or anticipated level of the reference rate, the market value of the notes is expected to decrease and you may receive substantially less than 100% of the issue price if you sell your notes prior to maturity.

§   The inclusion of commissions and projected profit from hedging in the original issue price is likely to adversely affect secondary market prices.  Assuming no change in market conditions or any other relevant factors, the price, if any, at which MS & Co. is willing to purchase the notes at any time in secondary market transactions will likely be significantly lower than the original issue price, since secondary market prices are likely to exclude commissions paid with respect to the notes and the cost of hedging our obligations under the notes that are included in the original issue price.  The cost of hedging includes the projected profit that our subsidiaries may realize in consideration for assuming the risks inherent in managing the hedging transactions.  These secondary market prices are also likely to be reduced by the costs of unwinding the related hedging transactions.  In addition, any secondary market prices may differ from values determined by pricing models used by MS & Co., as a result of dealer discounts, mark-ups or other transaction costs.

Liquidity Risk

§   The notes will not be listed on any securities exchange and secondary trading may be limited.  The notes will not be listed on any securities exchange.  Therefore, there may be little or no secondary market for the notes.  MS & Co. may, but is not obligated to, make a market in the notes.  Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily.  Because we do not expect that other broker-dealers will participate significantly in the secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which MS & Co. is willing to transact.  If at any time MS & Co. were not to make a market in the notes, it is likely that there would be no secondary market for the notes.  Accordingly, you should be willing to hold your notes to maturity.

Conflicts of Interest

§   The issuer, its subsidiaries or affiliates may publish research that could affect the market value of the notes.  They also expect to hedge the issuer’s obligations under the notes.   The issuer or one or more of its affiliates may, at present or in the future, publish research reports with respect to movements in interest rates generally or the reference rate specifically. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding the notes.Any of these activities may affect the market value of the notes.  In addition, the issuer’s subsidiaries expect to hedge the issuer’s obligations under the notes and they may realize a profit from that expected hedging activity even if investors do not receive a favorable investment return under the terms of the notes or in any secondary market transaction.

§   The calculation agent, which is a subsidiary of the issuer, will make determinations with respect to the notes.  Any of these determinations made by the calculation agent may adversely affect the payout to investors.  Determinations made by the calculation agent, including with respect to the reference rate may adversely affect the payout to you on the notes.

Supplemental Information Concerning Plan of Distribution; Conflicts of Interest

We expect to deliver the notes against payment therefor in New York, New York on June 20, 2012, which will be the       scheduled business day following the date of the pricing of the notes.  Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise.  Accordingly, purchasers who wish to trade notes on the date of pricing or on or prior to the third business day prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

Morgan Stanley or one of our affiliates will pay varying discounts and commissions to dealers, including Morgan Stanley Smith Barney LLC (“MSSB”) and their financial advisors, of up to $15 per note depending on market conditions.  The agent may distribute the notes through MSSB, as selected dealer, or other dealers, which may include Morgan Stanley & Co. International plc (“MSIP”) and Bank Morgan Stanley AG.  MSSB, MSIP and Bank Morgan Stanley AG are affiliates of Morgan Stanley.

MS & Co. is our wholly-owned subsidiary.  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.

Tax Considerations

In the opinion of our counsel, Davis Polk & Wardwell LLP, the notes will be treated as “variable rate debt instruments” for U.S. federal tax purposes.  The notes will be treated as providing for a single fixed rate followed by a qualified floating rate (“QFR”), as described in the sections of the accompanying prospectus supplement called “United States Federal Taxation―Tax Consequences to U.S. Holders―Notes―Floating Rate Notes―General” and “―Floating Rate Notes that Provide for Multiple Rates.”  Under applicable Treasury Regulations, solely for the purpose of determining any original issue discount (“OID”) on the notes, the initial fixed rate is converted to a QFR (the “replaced QFR”).  The replaced QFR must be such that the fair market value of the notes on the issue date is approximately the same as the fair market value of otherwise identical notes that provide for the replaced QFR (rather than the fixed rate) for the initial period.  In determining the qualified stated interest (“QSI”) and any OID on the notes, the notes must then be converted into “equivalent” fixed rate debt instruments by substituting each QFR provided under the terms of the notes (including the replaced QFR) with a fixed rate equal to the value of the QFR on the issue date of the notes.  Under this method, the notes may be issued with OID.

A U.S. holder is required to include any QSI in income in accordance with the holder’s regular method of accounting for U.S. federal income tax purposes.  U.S. holders will be required to include OID in income for U.S. federal income tax purposes as it accrues, in accordance with a constant yield method based on a compounding of interest, without regard to the timing of the receipt of cash payments attributable to this income.  QSI allocable to an accrual period must be increased (or decreased) by the amount, if any, which the interest actually accrued or paid during an accrual period (including the fixed rate payments made during the initial period) exceeds (or is less than) the interest assumed to be accrued or paid during the accrual period under the “equivalent” fixed rate debt instrument.  Both U.S. and non-U.S. holders should read the section of the accompanying prospectus supplement entitled “United States Federal Taxation.”

You should consult your tax advisers regarding all aspects of the U.S. federal tax consequences of an investment in the notes, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

The discussion in the preceding paragraphs under “Tax Considerations” and the discussion contained in the section entitled “United States Federal Taxation” in the accompanying prospectus supplement, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the notes.
