One Time Issuer Conversion Right into LIBOR Floating Rate Notes
Global Medium Term Notes, Series F
We, Morgan Stanley, will issue the notes initially as fixed rate notes, which will pay interest semi-annually at a rate of       % per annum (to be determined on the pricing date).  On October 23, 2009, we may elect to exercise our coupon conversion right to convert the notes in whole, and not in part, so that instead of paying a fixed rate of interest semi-annually, the notes will pay interest quarterly at the floating rate of 3 Month U.S. Dollar LIBOR plus 1.00% per annum.  If we decide to exercise our coupon conversion right, we will give you notice at least 10 business days before the conversion date.
We describe the basic features of these notes in the accompanying prospectus under the captions “Description of Debt Securities—Fixed Rate Debt Securities” and “Description of Debt Securities—Floating Rate Debt Securities” and in the accompanying prospectus supplement under the caption “Description of Notes,” subject to and as modified by the provisions described below.

Risk Factors
The market price of the notes prior to the conversion date will be influenced by the issuer’s right to convert the notes to a floating interest rate in light of then-prevailing market interest rates
 
While several factors will influence the value of the notes in the secondary market, we expect that prior to the conversion date, prevailing market interest rates, our right to convert the notes to a floating interest rate and with the time remaining to the conversion date will together affect the value of the notes more than any other factors.  We have the sole right to decide whether to exercise our coupon conversion right and our decision will depend on movements in market interest rates compared to the notes’ fixed interest rate.  We are more likely to exercise our coupon conversion right and pay the floating interest rate if market interest rates fall below the fixed interest rate at the time of the conversion date.  As a result, decreases in market interest rates below the fixed interest rate initially paid on the notes may not increase the value of the notes as the notes would more likely be converted to a floating interest rate if such lower interest rates continue to prevail at the time of the conversion date.  Conversely, if market interest rates rise above the fixed interest rate, we are less likely to exercise our coupon conversion right.  In these circumstances, you would not receive those higher market interest rates for the remaining term of the notes and the value of the notes would likely decline as a result.
 
Supplemental Information Concerning Plan of Distribution
We expect to deliver the notes against payment therefore in New York, New York on October 23, 2007, 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.
 
United States Federal Income Taxation
Although the treatment of the notes for U.S. federal income tax purposes is not clear, we intend to treat, and pursuant to the terms of the notes, you agree (in the absence of an administrative determination or judicial ruling to the contrary) to characterize the notes for all tax purposes as debt instruments not subject to the Treasury regulations governing contingent payment debt instruments (the “Contingent Debt Regulations”).  Assuming this characterization is respected, interest paid on a note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the holder’s method of accounting for U.S. federal income tax purposes.  Gain or loss realized on the sale, exchange or retirement of a note will generally be capital gain or loss and will be long term capital gain or loss if at the time of sale, exchange or retirement the note has been held for more than one year.
 
If the Internal Revenue Service were successful in asserting that the Contingent Debt Regulations applied to the notes, the timing and character of income thereon would be significantly affected.  Among other things, a U.S. Holder would be required to accrue original issue discount (regardless of the U.S. Holder’s method of accounting) on the notes every year at a “comparable yield” determined at the time of their issuance, which is based on our cost of borrowing.  Accruals will be subject to certain adjustments, as noted in the section of the accompanying prospectus supplement called “United States Federal Taxation — Tax Consequences to U.S. Holders — Optionally Exchangeable Notes — Adjustments to Interest Accruals on the Notes.”  We do not believe that the “comparable yield” would be higher than the fixed interest rate paid on the notes.  Furthermore, any gain realized by a U.S. Holder at maturity or upon a sale or other disposition of the notes (other than gain realized after the lapse of our coupon conversion right) would generally be treated as ordinary income.  U.S. investors should read the section of the accompanying prospectus supplement called “United States Federal

If you are a non-U.S. investor, please also read the section of the accompanying prospectus supplement called “United States Federal Taxation — Tax Consequences to Non-U.S. Holders.”  Non-U.S. investors should consult their own tax advisors regarding the potential tax consequences of an investment in the notes.
 
You are urged to consult your own tax advisors regarding all aspects of the U.S. federal tax consequences of investing in the notes, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.
