Senior Floating Rate Notes due 2026
Leveraged CMS Curve and S&P 500® Index Linked Notes

The notes are debt securities of Morgan Stanley. In year 1, the notes pay interest at a rate of 11.00% per
annum. Beginning June 30, 2012, interest wil accrue on the notes for each day that the closing value of the S&P 500®
Index is at or above 935, at a variable rate per annum equal to 4 times the CMS reference index for the related quarterly
interest payment period; subject to the maximum interest rate of 12.00% per annum per interest payment period and the
minimum interest rate of 0.00% per annum. The floating interest rate is based on the CMS reference index and the level of
the S&P 500 index. If 30CMS is less than or equal to 2CMS on the applicable CMS reference determination date, the
floating interest rate wil be 0.00% and no interest wil accrue on the notes for such interest period. In addition, if on any
calendar day during the interest payment period the index closing value is less than the index reference level, interest wil
accrue at a rate of 0.00% per annum for that day. 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 cal ed "Description of Notes," subject to and as modified by the provisions described below.

Al payments on the notes are subject to the credit risk of Morgan Stanley. The stated principal amount of each note is
$1,000 and the issue price is variable. The issue price of the notes includes the agent's commissions paid with respect to
the notes as wel 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. This
cost of hedging could be significant due to the term of the notes and the tailored exposure provided by the notes. The
secondary market price, if any, at which MS & Co. is wil ing 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."

CMS Reference Index

What are the 30-Year and 2-Year Constant Maturity Swap Rates?

The 30-Year Constant Maturity Swap Rate (which we refer to as "30CMS") is, on any day, the fixed rate of interest
payable on an interest rate swap with a 30-year maturity as reported on Reuters Page ISDAFIX1 or any successor page
thereto at 11:00 a.m. New York City time on that day; provided that for the determination of 30CMS on any calendar day,
the "CMS reference determination date" shall be that calendar day unless that calendar day is not a U.S. government
securities business day, in which case the 30CMS level shal be the 30CMS level on the immediately preceding U.S.
government securities business day. This rate is one of the market-accepted indicators of longer-term interest rates.

The 2-Year Constant Maturity Swap Rate (which we refer to as "2CMS") is, on any day, the fixed rate of interest payable
on an interest rate swap with a 2-year maturity as reported on Reuters Page ISDAFIX1 or any successor page thereto at
11:00 a.m. New York City time on that day; provided that for the determination of 2CMS on any calendar day, the "CMS
reference determination date" shall be that calendar day unless that calendar day is not a U.S. government securities
business day, in which case the 2CMS level shall be the 2CMS level on the immediately preceding U.S. government
securities business day. This rate is one of the market-accepted indicators of shorter-term interest rates.

An interest rate swap rate, at any given time, general y indicates the fixed rate of interest (paid semi-annual y) that a
counterparty in the swaps market would have to pay for a given maturity, in order to receive a floating rate (paid quarterly)
equal to 3-month LIBOR for that same maturity.

Senior Floating Rate Notes due 2026
Leveraged CMS Curve and S&P 500® Index Linked Notes

CMS Rate Fallback Provisions

If 30CMS or 2CMS is not displayed by 11:00 a.m. New York City time on the Reuters Screen ISDAFIX1 Page on any day
on which the level of the CMS reference index must be determined, the rate for such day wil be determined on the basis of
the mid-market semi-annual swap rate quotations to the calculation agent provided by five leading swap dealers in the New
York City interbank market (the "Reference Banks") at approximately 11:00 a.m., New York City time, on such day, and, for
this purpose, the mid-market semi-annual swap rate means the mean of the bid and offered rates for the semi-annual fixed
leg, calculated on a 30/360 day count basis, of a fixed-for-floating U.S. Dol ar interest rate swap transaction with a term
equal to the applicable 30 year or 2 year maturity commencing on such day and in a representative amount with an
acknowledged dealer of good credit in the swap market, where the floating leg, calculated on an actual/360 day count
basis, is equivalent to USD-LIBOR-BBA with a designated maturity of three months. The calculation agent wil request the
principal New York City office of each of the Reference Banks to provide a quotation of its rate. If at least three quotations
are provided, the rate for that day wil be the arithmetic mean of the quotations, eliminating the highest quotation (or, in the
event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest). If fewer than
three quotations are provided as requested, the rate wil be determined by the calculation agent in good faith and in a
commercially reasonable manner.

The S&P 500® Index

The S&P 500® Index (the "index" or the "S&P 500 Index"), which is calculated, maintained and published by Standard &
Poor's Financial Services LLC. ("S&P" or the "index publisher"), consists of 500 component stocks selected to provide a
performance benchmark for the U.S. equity markets. The calculation of the index is based on the relative value of the float
adjusted aggregate market capitalization of the 500 component companies as of a particular time as compared to the
aggregate average market capitalization of the 500 similar companies during the base period of the years 1941 through
1943. The index is described under "Annex A--The S&P 500® Index" herein.

Index Closing Value Fallback Provisions

The index closing value on any calendar day beginning June 30, 2012, on which the index level is to be determined (each,
an "index determination date") wil equal the official closing value of the index as published by the index publisher or its
successor, or in the case of any successor index, the official closing value for any such successor index as published by the
publisher of such successor index or its successor, at the regular weekday close of trading on that calendar day, as
determined by the calculation agent; provided that the index closing value for any day from and including the fifth trading
day prior to the related interest payment date for any interest payment period shal be the index closing value in effect on
such fifth trading day prior to such interest payment date; provided further that if a market disruption event with respect to
the index occurs on any index determination date or if any such index determination date is not an index business day, the
closing value of the index for such index determination date wil be the closing value of the index on the immediately
preceding index business day on which no market disruption event has occurred. In certain circumstances, the index
closing value shal be based on the alternate calculation of the index described under "Annex A--The S&P 500® Index--
Discontinuance of the S&P 500 Index; Alteration of Method of Calculation."

"Index business day" means a day, as determined by the calculation agent, on which trading is general y conducted on each
of the relevant exchange(s) for the 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.

"Relevant exchange" means the primary exchange(s) or market(s) of trading for (i) any security then included in the index,
or any successor index, and (i ) any futures or options contracts related to the index or to any security then included in the
index.

Senior Floating Rate Notes due 2026
Leveraged CMS Curve and S&P 500® Index Linked Notes

The table below presents examples of hypothetical interest that would accrue on the notes during any quarter in the floating
interest rate period. The examples below are for purposes of il ustration only. The examples of the hypothetical floating
interest rate that would accrue on the notes are based both on the level of the CMS reference index level on the applicable
CMS reference determination date and on the total number of calendar days in a quarterly interest payment period on
which the index closing value of the S&P 500® Index is greater than or equal to 935.

The actual interest payments during the floating interest rate period wil depend on the actual level of the CMS reference
index on each CMS reference determination date and the index closing value of the S&P 500 index on each day during the
floating interest payment period. The applicable interest rate for each quarterly interest payment period wil be determined
on a per-annum basis but wil apply only to that interest payment period. The table assumes that the interest payment
period contains 90 calendar days. The examples below are for purposes of il ustration only and would provide different
results if different assumptions were made.

The CMS Reference Index

The fol owing graph sets forth the historical difference between the 30-Year Constant Maturity Swap Rate and the 2-Year
Constant Maturity Swap Rate for the period from January 1, 1996 to June 27, 2011 (the "historical period"). The historical
difference between the 30-Year Constant Maturity Swap Rate and the 2-Year Constant Maturity Swap Rate should not be
taken as an indication of the future performance of the CMS reference index. The graph below does not reflect the return
the notes would have had during the periods presented because it does not take into account the index closing values or
the leverage factor. We cannot give you any assurance that the level of the CMS reference index wil be positive on any
CMS reference determination date. We obtained the information in the graph below, without independent verification, from
Bloomberg Financial Markets ("USSW"), which closely paral els but is not necessarily exactly the same as the Reuters
Page price sources used to determine the level of the CMS reference index.

*The bold line in the graph indicates the CMS reference index strike of 0.00%.

The historical performance shown above is not indicative of future performance. The CMS reference index level may be
negative on one or more specific CMS reference determination dates during the floating interest rate period even if the level
of the CMS reference index is general y positive and, moreover, the level of the CMS reference index has in the past been,
and may in the future be, negative.
