Morgan Stanley Capital Trust VI

         Morgan Stanley Trust is a Delaware statutory trust. Morgan Stanley
Trust exists solely to:

         o   issue and sell its common securities to Morgan Stanley;

         o   issue and sell its capital securities to the public;

         o   use the proceeds from the sale of its common securities and
             capital securities to purchase junior subordinated debentures
             from Morgan Stanley; and

         o   engage in other activities that are necessary, convenient or
             incidental to these purposes.

         The Bank of New York will act as the property trustee of Morgan
Stanley Trust. The Bank of New York (Delaware) will act as the Delaware
trustee of Morgan Stanley Trust. Two employees, officers or affiliates of
Morgan Stanley or its subsidiaries will act as administrators of Morgan
Stanley Trust. The principal offices and telephone number of Morgan Stanley
Trust are 1585 Broadway, New York, New York 10036 and (212) 761-4000.

The Offering

         Morgan Stanley Trust is offering its capital securities for $25 per
security. Morgan Stanley Trust will use all of the proceeds from the sale of
its capital securities and its common securities to purchase junior
subordinated debentures of Morgan Stanley. The junior subordinated debentures
will be Morgan Stanley Trust's only assets. Morgan Stanley will fully and
unconditionally guarantee the obligations of Morgan Stanley Trust, based on
its combined obligations under a guarantee, a trust agreement and a junior
subordinated debt indenture.

         The Capital Securities

         If you purchase capital securities, you will be entitled to receive
cumulative cash distributions at an annual rate of $1.65 for each capital
security, which represents 6.60% of the liquidation amount of $25 for each
capital security. If Morgan Stanley Trust is dissolved and its assets
distributed, for each capital security you own you are entitled to receive the
liquidation amount (which may be paid in the form of a distribution of a like
amount of junior subordinated debentures) of $25 plus accumulated but unpaid
distributions from the assets of Morgan Stanley Trust available for
distribution, after it has paid or made reasonable provision to pay, in
accordance with Section 3808(e) of the Delaware Statutory Trust Act,
liabilities owed to its creditors. See "Description of Capital
Securities--Liquidation Distribution upon Dissolution." Accordingly, you may
not receive the full liquidation amount and accumulated but unpaid
distributions if Morgan Stanley Trust does not have enough funds.




                                     S-4


         Distributions will accumulate from the date Morgan Stanley Trust
issues its capital securities. Morgan Stanley Trust will pay the distributions
quarterly on February 1, May 1, August 1 and November 1 of each year,
beginning May 1, 2006. These distributions may be deferred for up to 20
consecutive quarters. Morgan Stanley Trust will only pay distributions when it
has funds available for payment.

         If you purchase the capital securities, you will have limited voting
rights. You will be entitled to vote on the following matters:

         o   removal of the property trustee or the Delaware trustee when
             there is a default under the junior subordinated debentures;

         o   certain modifications to the terms of the capital securities and
             the guarantee; and

         o   the exercise of Morgan Stanley Trust's rights as holder of the
             junior subordinated debentures.

         A more detailed description of your voting rights is contained under
"Description of Capital Securities--Removal of Morgan Stanley Capital
Trustees; Appointment of Successors," "--Voting Rights; Amendment of Trust
Agreements" and "Description of Guarantees--Amendments and Assignment" on
pages 10, 12 and 25, respectively, of the accompanying prospectus.

         The Common Securities

         Morgan Stanley will acquire all of the common securities of Morgan
Stanley Trust. The common securities will have an aggregate liquidation amount
of at least 3% of the total capital of Morgan Stanley Trust. Except as
described under "Ranking" below, the common securities will rank equal to the
capital securities in priority of payment. Normally, the common securities
will have sole voting power on matters to be voted upon by Morgan Stanley
Trust's security holders.

         The Junior Subordinated Debentures

         Morgan Stanley Trust will purchase the junior subordinated debentures
from Morgan Stanley with the proceeds from the sale of its capital securities
and its common securities. Morgan Stanley will issue the junior subordinated
debentures under a junior subordinated debt indenture between Morgan Stanley
and The Bank of New York, as indenture trustee. The junior subordinated
debentures will:

         o   have an aggregate principal amount equal to $773,195,900, which
             is the aggregate liquidation amount of the capital securities
             plus the capital contributed by Morgan Stanley for the common
             securities;

         o   bear interest at an annual rate of 6.60%;

         o   pay interest quarterly, subject to the right of Morgan Stanley to
             defer interest payments for up to 20 consecutive quarters
             as described below; and

         o   mature on February 1, 2046, although Morgan Stanley may redeem
             them earlier under the circumstances described below.




                                     S-5



         The Guarantee of the Capital Securities

         Morgan Stanley will guarantee the capital securities on a limited
basis under the guarantee.

         The guarantee requires Morgan Stanley to pay accumulated but unpaid
distributions, redemption payments and liquidation payments on the capital
securities on behalf of Morgan Stanley Trust only in an amount equal to the
sum of the payments Morgan Stanley has made to Morgan Stanley Trust on the
junior subordinated debentures. It does not, however, require Morgan Stanley
to make payments on behalf of Morgan Stanley Trust if Morgan Stanley Trust
does not have sufficient funds to make payments on the capital securities
because Morgan Stanley has not made payments on the junior subordinated
debentures.

         Ranking

         The capital securities will generally rank equal to the common
securities in priority of payment. Morgan Stanley Trust will make payments on
the capital securities and the common securities based on a proportionate
allocation of the payments it receives on the junior subordinated debentures.
However, the capital securities will rank prior to the common securities as to
payment if there occurs with respect to the junior subordinated debentures an
event of default or a default as a result of a failure to pay any amounts
under the junior subordinated debentures when due. For a more detailed
explanation, see "Description of Capital Securities--Subordination of Common
Securities" on page 9 of the accompanying prospectus.

         The junior subordinated debentures and the guarantee will be
unsecured and will rank subordinate and junior in right of payment to all of
Morgan Stanley's current and future senior indebtedness, liabilities and
obligations (including senior subordinated debt of Morgan Stanley) and will be
effectively subordinated to all indebtedness and other liabilities of Morgan
Stanley's subsidiaries. The junior subordinated debentures and the guarantee
will rank pari passu with junior subordinated debt of Morgan Stanley
underlying the existing capital securities of Morgan Stanley Capital Trust II,
Morgan Stanley Capital Trust III, Morgan Stanley Capital Trust IV and Morgan
Stanley Capital Trust V (collectively, the "Existing Morgan Stanley Trusts")
and guarantees by Morgan Stanley of the capital securities issued by the
Existing Morgan Stanley Trusts. However, the junior subordinated debentures
have a more expansive definition of senior indebtedness than the junior
subordinated debt of Morgan Stanley underlying the Existing Morgan Stanley
Trusts and guarantees by Morgan Stanley of the capital securities issued by
the Existing Morgan Stanley Trusts and will have more limited events of
default. See "Risk Factors--While the Junior Subordinated Debentures and
Guarantees Will Be Pari Passu With Those Underlying the Existing Morgan
Stanley Trusts, the Junior Subordinated Debentures Have a Broader Definition
of Senior Indebtedness Than the Existing Junior Subordinated Debentures and
Will Be Subject to More Limited Events of Default Than Those That Apply to the
Existing Junior Subordinated Debentures" beginning on page S-9, "Description
of Junior Subordinated Debentures--Subordination" beginning on page S-26,
"Description of Junior Subordinated Debentures" beginning on page 14 of the
accompanying prospectus and "Description of Guarantees--Status of the
Guarantees" on page 25 of the accompanying prospectus for a more detailed
explanation.

         Deferral of Distributions

         Unless there is an event of default under the junior subordinated
debentures, Morgan Stanley can defer interest payments on the junior
subordinated debentures during any period of up to 20 consecutive quarters,
but not beyond their maturity date. After Morgan Stanley makes all interest
payments that it has deferred, including accrued interest on the deferred
payments, Morgan Stanley can again defer interest payments during new periods
of up to 20 consecutive quarters as long as Morgan Stanley adheres to the same
requirements.




                                     S-6


         If Morgan Stanley defers interest payments on the junior subordinated
debentures, Morgan Stanley Trust will defer distributions on the capital
securities. During any deferral period, distributions will continue to
accumulate on the capital securities at an annual rate of 6.60% of the
liquidation amount of $25 per capital security. Also, the deferred
distributions will accrue additional distributions, as permitted by applicable
law, at an annual rate of 6.60%, compounded quarterly.

         While Morgan Stanley defers interest payments on the junior
subordinated debentures, Morgan Stanley will generally not be permitted to:

         o    declare or pay any dividends or any distributions on, or redeem,
              purchase, acquire or make a liquidation payment on, any of
              its capital stock; or

         o    make any payment of principal of or interest or premium, if any,
              on or repay, repurchase or redeem debt securities of Morgan
              Stanley that rank equal or junior to the junior subordinated
              debentures.

         If Morgan Stanley defers payments of interest on the junior
subordinated debentures, the capital securities would at that time be treated
as being issued with original issue discount for United States federal income
tax purposes. This means that you would be required to include accrued
interest in your income for United States federal income tax purposes before
you receive any cash distributions. Please see "United States Federal Income
Tax Consequences" on page S-37 for a more complete discussion.

         Redemption of Capital Securities and the Junior Subordinated
         Debentures

         Morgan Stanley Trust will redeem all of the outstanding capital
securities and common securities when Morgan Stanley redeems the junior
subordinated debentures or repays the junior subordinated debentures at
maturity on February 1, 2046. If Morgan Stanley redeems any junior
subordinated debentures before their maturity, Morgan Stanley Trust will use
the cash it receives from the redemption to redeem capital securities and
common securities.

         Except as described above under "Ranking," the aggregate liquidation
amount of capital and common securities to be redeemed will be allocated
approximately 97% to the capital securities and approximately 3% to the common
securities.

         Subject to obtaining any then required regulatory approval, Morgan
Stanley can redeem the junior subordinated debentures before their maturity at
100% of their principal amount plus accrued interest to the date of
redemption:

         o    on or after February 1, 2011, in whole or in part, on one or
              more occasions, at any time;

         o    before February 1, 2011, in whole only and only if adverse
              changes in tax or investment company law described on pages S-18
              and S-19 occur and are continuing; and

         o    at any time, in whole or in part, upon adverse changes in the
              policies or rules and regulations relating to capital treatment
              of the Securities and Exchange Commission (the "SEC") or of any
              applicable regulatory body or governmental authority, as
              described under "Description of Capital Securities--Redemption"
              beginning on page S-18.




                                     S-7



         Distribution of the Junior Subordinated Debentures

         Subject to obtaining any then required regulatory approval, Morgan
Stanley has the right to terminate Morgan Stanley Trust at any time. If Morgan
Stanley decides to exercise its right to terminate Morgan Stanley Trust,
Morgan Stanley Trust will distribute approximately 97% of the junior
subordinated debentures to holders of the capital securities and approximately
3% to the holders of the common securities. However, if there occurs with
respect to the junior subordinated debentures an event of default or a default
as a result of a failure to pay any amounts due under the junior subordinated
debentures, holders of capital securities will have priority over holders of
common securities as described under "Ranking" above. If the junior
subordinated debentures are distributed, Morgan Stanley will use its
reasonable best efforts to list the junior subordinated debentures on the New
York Stock Exchange or any other exchange on which the capital securities are
then listed.

         Use of Proceeds

         Morgan Stanley Trust will use all of the proceeds from the sale of
its capital securities and its common securities to purchase the junior
subordinated debentures of Morgan Stanley. Morgan Stanley intends to use the
net proceeds from the sale of the junior subordinated debentures for general
corporate purposes.

         Listing of the Capital Securities

         Morgan Stanley will apply to list the capital securities on the New
York Stock Exchange for trading within 30 days after they are first issued. No
assurance can be given, however, that the New York Stock Exchange will approve
the capital securities for listing. You should be aware that the listing of
the capital securities will not necessarily ensure that a liquid trading
market will be available for the capital securities or that you will be able
to sell your capital securities at the price you originally paid for them.

         Risk Factors

         Your investment in the capital securities will involve risks. You
should carefully consider the discussion of risks that follows below in the
section entitled "Risk Factors," and the other information in this prospectus
supplement and the accompanying prospectus, before deciding whether an
investment in the capital securities is suitable for you.

         Form of Capital Securities

         The capital securities will be represented by one or more global
securities that will be deposited with and registered in the name of The
Depository Trust Company ("DTC") or its nominee. This means that you will not
receive a certificate for your capital securities and the capital securities
will not be registered in your name. Rather, your broker or other direct or
indirect participant of DTC will maintain your position in the capital
securities.



                                     S-8



                                 RISK FACTORS

         An investment in the capital securities involves a number of risks.
You should carefully review the information contained in the other sections of
this prospectus supplement and the accompanying prospectus and should
particularly consider the following matters before purchasing any capital
securities.

         Because Morgan Stanley Trust will rely on the payments it receives on
the junior subordinated debentures to fund all payments on the capital
securities, and because Morgan Stanley Trust may distribute the junior
subordinated debentures in exchange for the capital securities, you are making
an investment decision with regard to the junior subordinated debentures as
well as the capital securities. You should carefully review the information in
this prospectus supplement and the accompanying prospectus about both of these
securities and the guarantee.

Holders of Morgan Stanley's Senior Indebtedness Will Get Paid Before Morgan
Stanley Trust Will Get Paid Under the Junior Subordinated Debentures and
Before You Will Get Paid Under the Guarantee

         Morgan Stanley's obligations under the junior subordinated debentures
and the guarantee are unsecured and will rank in priority of payment junior to
all of Morgan Stanley's current and future senior indebtedness, liabilities
and obligations, including senior subordinated debt of Morgan Stanley and
obligations of Morgan Stanley in respect of interest rate, foreign exchange
rate and commodity forward contracts, options and swaps and similar
arrangements ("derivative contracts"). As of August 31, 2005, there were (1)
approximately $131 billion of senior indebtedness of Morgan Stanley (including
approximately $12 billion of senior indebtedness consisting of guaranteed
obligations of the indebtedness of subsidiaries) recorded as debt on Morgan
Stanley's consolidated balance sheet and (2) approximately $48 billion of
senior indebtedness recorded as financial instruments sold, not yet
purchased-derivative contracts on Morgan Stanley's consolidated balance sheet.

         Morgan Stanley's obligations under the junior subordinated debentures
and the guarantee will also be effectively subordinated to all current and
future indebtedness and other liabilities of its subsidiaries.

         The capital securities, the junior subordinated debentures and the
guarantee do not limit the ability of Morgan Stanley or any of its
subsidiaries to incur additional indebtedness, liabilities and obligations,
including indebtedness, liabilities and obligations that rank senior to or
equal with the junior subordinated debentures and the guarantee. For more
information on the ranking of Morgan Stanley's obligations under the junior
subordinated debentures and the guarantee, see "Description of Junior
Subordinated Debentures" beginning on page 14 of the accompanying prospectus
and "Description of Guarantees--Status of the Guarantees" on page 25 of the
accompanying prospectus.

While the Junior Subordinated Debentures and Guarantees Will Be Pari Passu
With Those Underlying the Existing Morgan Stanley Trusts, the Junior
Subordinated Debentures Have a Broader Definition of Senior Indebtedness Than
the Existing Junior Subordinated Debentures and Will Be Subject to More
Limited Events of Default Than Those That Apply to the Existing Junior
Subordinated Debentures

         Morgan Stanley currently has outstanding four series of junior
subordinated debentures, which were issued under a junior subordinated
indenture, dated March 1, 1998, between Morgan Stanley and The Bank of New
York and purchased, respectively, by Morgan Stanley Capital Trust II, Morgan
Stanley Capital Trust III, Morgan Stanley Capital Trust IV and Morgan Stanley
Capital Trust V (the "existing junior subordinated debentures") with terms and
conditions substantially similar to those of the junior subordinated
debentures described in this prospectus supplement except as described below.
At August 31, 2005, there was $2,881 million aggregate principal amount of
existing junior subordinated debentures outstanding. While the junior
subordinated debentures and guarantees underlying the capital securities
described in this prospectus supplement will be pari




                                     S-9


passu with those underlying the Existing Morgan Stanley Trusts, the definition
of senior indebtedness that applies to the junior subordinated debentures
described in this prospectus supplement (which definition includes, for
example, obligations of Morgan Stanley in respect of interest rate, foreign
exchange rate and commodity forward contracts, options and swaps and similar
arrangements) is broader than the definition of senior indebtedness that
applies to the existing junior subordinated debentures and, thus, their right
to payment upon Morgan Stanley's bankruptcy or insolvency may be more limited.
In addition, the events of default relating to the junior subordinated
debentures described in this prospectus supplement are more limited than the
events of default for the existing junior subordinated debentures. The
existing junior subordinated debentures contain certain acceleration
provisions that could be triggered prior to the acceleration provisions of the
junior subordinated debentures described in this prospectus supplement.
Accordingly, the outstanding amount of the existing junior subordinated
debentures could become due and payable prior to the junior subordinated
debentures described in this prospectus supplement.

If Morgan Stanley Does Not Make Payments on the Junior Subordinated Debentures,
Morgan Stanley Trust Will Not Be Able to Pay Distributions on the Capital
Securities and the Guarantee Will Not Apply

         The ability of Morgan Stanley Trust to pay distributions on the
capital securities and the liquidation amount of $25 per capital security in a
timely manner depends solely upon Morgan Stanley's making the related payments
on the junior subordinated debentures when due. If Morgan Stanley defaults on
its obligation to pay the principal of or interest on the junior subordinated
debentures, Morgan Stanley Trust will not have sufficient funds to pay
distributions on, or the $25 liquidation amount per security of, the capital
securities.

         In that case, you will not be able to rely upon the guarantee for
payment of these amounts because the guarantee only applies if Morgan Stanley
makes the corresponding payment of principal of or interest on the junior
subordinated debentures. Instead, you or the property trustee will have to
bring a legal action against Morgan Stanley to enforce the property trustee's
rights under the indenture relating to the junior subordinated debentures.

         See "You May Not Be Able to Enforce Your Rights Against Morgan
Stanley Directly If an Event of Default Occurs; You May Have to Rely on the
Property Trustee to Enforce Your Rights" immediately below for more
information on how to bring a legal action against Morgan Stanley.

You May Not Be Able to Enforce Your Rights Against Morgan Stanley Directly If
an Event of Default Occurs; You May Have to Rely on the Property Trustee to
Enforce Your Rights

         You will not always be able to directly enforce your rights against
Morgan Stanley if an event of default occurs.

         If a default under the junior subordinated debentures occurs and is
continuing, that event will also be an event of default under the capital
securities. In that case, you may have to rely on the property trustee, as the
holder of the junior subordinated debentures, to enforce your rights against
Morgan Stanley. Within ten business days after the occurrence of an event of
default under the capital securities that is actually known to the property
trustee, the property trustee will transmit notice of the event of default to
the holders of the capital securities and common securities and the
administrators, unless the event of default has been cured or waived. In
addition, the property trustee will notify each holder of the capital
securities of any notice of default received by it with respect to the junior
subordinated debentures. See "Description of Capital Securities--Capital
Securities Events of Default; Notice" beginning on page 9 of the accompanying
prospectus.

         Upon a default under the junior subordinated debentures, a majority
in aggregate liquidation amount of the holders of outstanding capital
securities may remove the Delaware trustee or property trustee. In general,
only



                                     S-10


Morgan Stanley, as the sole holder of the common securities of Morgan
Stanley Trust, can replace or remove any of the trustees of Morgan Stanley
Trust.

         You may bring a legal action against Morgan Stanley directly only if
the event of default under the trust agreement has occurred and is continuing
because of Morgan Stanley's failure to pay when due interest on, or the
principal of, the junior subordinated debentures. See "Description of Junior
Subordinated Debentures--Events of Default, Defaults and the Rights of Capital
Securities Holders to Take Action Against Morgan Stanley" on page S-32.

Distributions on the Capital Securities Could Be Deferred; You May Have to
Include Interest in Your Taxable Income Before You Receive Cash

         As long as there is no event of default under the junior subordinated
debentures, Morgan Stanley may defer interest payments on the junior
subordinated debentures one or more times. Each deferral period may last for
up to 20 consecutive quarters, but not beyond the maturity date of the junior
subordinated debentures. During a deferral period, Morgan Stanley Trust will
defer distributions on the capital securities in a corresponding amount.

         If Morgan Stanley defers interest payments on the junior subordinated
debentures and Morgan Stanley Trust defers distributions on the capital
securities, you will have to accrue interest income as original issue discount
for United States federal income tax purposes on your proportionate share of
the deferred interest on the junior subordinated debentures held by Morgan
Stanley Trust. As a result, you would have to include that accrued interest in
your gross income for United States federal income tax purposes before you
actually receive any cash attributable to that income. You will also not
receive the cash distribution related to any accrued and unpaid interest from
Morgan Stanley Trust if you sell the capital securities before the record date
for any deferred distributions, even if you held the capital securities on the
date that the payments would normally have been paid.

         Morgan Stanley has no current intention of exercising its right to
defer payments of interest on the junior subordinated debentures. However, if
Morgan Stanley exercises this right, the market price of the capital
securities may be adversely affected. If you sell your capital securities when
distributions are being deferred, you may not receive the same return on
investment as someone who continues to hold the capital securities. In
addition, because of Morgan Stanley's right to defer interest payments, the
market price of the capital securities may be more volatile than the market
prices of other securities that are not subject to interest deferrals.

         See "Description of Capital Securities--Deferral of Distributions"
beginning on page S-17, "Description of Junior Subordinated Debentures--Option
to Extend Interest Payment Period" on page S-27 and "United States Federal
Income Tax Consequences--U.S. Holders--Interest Income and Original Issue
Discount" and "--Sales of Capital Securities" on pages S-38 and S-40,
respectively, for more information regarding the interest payment deferral
option.

The Capital Securities May Be Redeemed Prior to Maturity; You May Be Taxed on
the Proceeds and You May Not Be Able to Reinvest the Proceeds at the Same or a
Higher Rate of Return

         If adverse changes in the tax laws, investment company law or the
policies or rules and regulations of the SEC or any applicable regulatory body
or governmental authority relating to capital treatment discussed on pages
S-18 and S-19 occur and are continuing, Morgan Stanley may redeem the junior
subordinated debentures, subject to obtaining any then required regulatory
approval and certain other conditions set forth under the heading "Description
of Capital Securities--Redemption." Morgan Stanley may also redeem the capital
securities at its option in whole or in part on one or more occasions at any
time on or after February 1, 2011, subject to obtaining any then required
regulatory approval.



                                     S-11


         If the junior subordinated debentures are redeemed, the capital
securities will be redeemed at a redemption price equal to the $25 liquidation
amount per capital security plus accumulated but unpaid distributions to but
excluding the redemption date. Under current United States federal income tax
law, early redemption of the capital securities would be a taxable event to
you.

         In addition, you may not be able to reinvest the money you receive
upon redemption at a rate that is equal to or higher than the rate of return
you receive on the capital securities.

         See "Description of Junior Subordinated Debentures--Redemption" on
page S-28, "Description of Capital Securities--Redemption" beginning on page
S-18 and "--Liquidation Distribution upon Dissolution" beginning on page S-21
for more information on redemption of the junior subordinated debentures.

Morgan Stanley Trust May Distribute the Junior Subordinated Debentures to the
Holders of the Capital Securities, and the Junior Subordinated Debentures May
Trade at a Price that Is Lower than the Price You Paid for the Capital
Securities

         If Morgan Stanley dissolves Morgan Stanley Trust before the maturity
of the junior subordinated debentures, the property trustee will distribute
the junior subordinated debentures to the holders of the capital securities
and the common securities in liquidation of Morgan Stanley Trust.

         No one can accurately predict the market prices for the junior
subordinated debentures that may be distributed. Accordingly, the junior
subordinated debentures that you receive upon a distribution, or the capital
securities you hold pending the distribution, may trade at a lower price than
what you paid to purchase the capital securities.

         Although Morgan Stanley has agreed to use its reasonable best efforts
to list the junior subordinated debentures on the New York Stock Exchange or
any other exchange on which the capital securities are then listed, Morgan
Stanley cannot assure you that the New York Stock Exchange will approve the
junior subordinated debentures for listing or that a trading market will exist
for the junior subordinated debentures.

         Under current United States federal income tax law, the distribution
of junior subordinated debentures upon the termination of Morgan Stanley Trust
would generally not be taxable to you. If, however, Morgan Stanley Trust is
characterized for United States federal income tax purposes as an association
taxable as a corporation at the time of the liquidation, the distribution of
the junior subordinated debentures would be taxable to you.

         Please see "Description of Capital Securities--Liquidation
Distribution upon Dissolution" beginning on page S-21 for more information.

If You Sell Your Capital Securities Before the Record Date for a Distribution
Payment, You Will Have to Include Accrued but Unpaid Distributions in Your
Taxable Income

         The capital securities may trade at prices that do not fully reflect
the value of accrued but unpaid interest on the underlying junior subordinated
debentures.

         If you dispose of your capital securities before the record date for
a distribution payment, you will have to treat a portion of your proceeds from
the disposition as ordinary income for United States federal income tax
purposes in an amount equal to the accrued but unpaid interest on your
proportionate share of the junior subordinated debentures through the date of
your disposition, even though the amount you receive for your capital
securities may not fully reflect the value of any accrued but unpaid interest
at the time of the disposition.




                                     S-12


         Upon the sale of your capital securities you will recognize a capital
loss if the amount you receive is less than your adjusted tax basis in the
capital securities. Normally, you may not apply capital losses to offset
ordinary income for United States federal income tax purposes.

         See "United States Federal Income Tax Consequences--U.S.
Holders--Sales of Capital Securities" on page S-40 for more information.

Morgan Stanley Generally Will Control Morgan Stanley Trust Because Your Voting
Rights Are Very Limited; Your Interests May Not Be the Same as Morgan
Stanley's Interests

         You will have limited voting rights. For example, you may not elect
or remove any trustees, except (1) when there is a default under the junior
subordinated debentures or (2) when holders of a majority in liquidation
amount of the outstanding capital securities decide to remove the Delaware
trustee or property trustee for cause. In general, only Morgan Stanley, as the
sole holder of the common securities of Morgan Stanley Trust, can replace or
remove any of the trustees of Morgan Stanley Trust.

         Morgan Stanley and the administrators of Morgan Stanley Trust, who
are employees or officers of Morgan Stanley or its affiliates, may amend the
trust agreement without the consent of holders of capital securities as
described under "Description of Capital Securities--Voting Rights; Amendment
of Trust Agreements" on page 12 of the accompanying prospectus.

An Active Trading Market for the Capital Securities May Not Develop

         The capital securities constitute a new issue of securities with no
established trading market. Although application will be made to list the
capital securities on the New York Stock Exchange, no assurance can be given
that the capital securities will be approved for listing. If approved for
listing, listing does not guarantee that a trading market for the capital
securities will develop or, if a trading market for the capital securities
does develop, the depth of that market or the ability of holders to sell their
capital securities easily.

If a Trading Market for the Capital Securities Does Develop, the Market Price
of the Capital Securities Will Be Influenced by Unpredictable Factors

         If a trading market for the capital securities does develop, several
factors will influence the trading price of the capital securities, including:

         o    interest and yield rates in the market;

         o    the time remaining to the maturity of the capital securities; and

         o    Morgan Stanley's creditworthiness.

Some or all of these factors will influence the price that you will receive if
you sell your capital securities prior to the maturity date.

                        MORGAN STANLEY CAPITAL TRUST VI

         Morgan Stanley Trust is a statutory trust formed under Delaware law
by:

         o    the execution of a trust agreement by Morgan Stanley, as
              depositor, and the trustees of Morgan Stanley Trust; and

         o    the filing of a certificate of trust with the Secretary of State
              of the State of Delaware.

         The capital securities offered hereby will constitute all of the
capital securities of Morgan Stanley Trust. Morgan Stanley, or one of its
affiliates, will acquire all of the common securities of Morgan Stanley Trust,
which have an aggregate liquidation amount equal to at least 3% of the total
capital of Morgan Stanley Trust.

         Morgan Stanley has agreed to pay all fees and expenses related to
Morgan Stanley Trust and the offering of the common securities and the capital
securities.

             CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES AND
            EARNINGS TO FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

         The following table sets forth Morgan Stanley's consolidated ratios
of earnings to fixed charges and earnings to fixed charges and preferred stock
dividends for the periods indicated.

                                 Nine Months Ended                                    Fiscal Year

  Ratio of earnings
     to fixed charges.......       1.3            1.5            1.5          1.5           1.4            1.3           1.5

         For purposes of calculating the ratio of earnings to fixed charges
and the ratio of earnings to fixed charges and preferred stock dividends,
earnings are the sum of:

         o    income before losses from unconsolidated investees, income taxes,
              (loss)/gain on discontinued operations, cumulative effect of
              accounting change and fixed charges;

         less:

         o    dividends on preferred securities subject to mandatory
              redemption.

         For purposes of calculating both ratios, fixed charges are the sum
of:

         o    interest cost, including interest on deposits;

         o    dividends on preferred securities subject to mandatory
              redemption; and

         o    that portion of rent expense estimated to be representative of
              the interest factor.

         The preferred stock dividend amounts represent pre-tax earnings
required to cover dividends on preferred stock.

                       DESCRIPTION OF CAPITAL SECURITIES

         The following, together with "Description of Capital Securities"
beginning on page 7 of the accompanying prospectus, is a description of the
material terms of the capital securities. You should also read the trust
agreement, the Delaware Statutory Trust Act and the Trust Indenture Act. A
form of the trust agreement is on file at the Securities and Exchange
Commission (the "SEC") as an exhibit to the registration statement pertaining
to this prospectus supplement and the accompanying prospectus.

         Morgan Stanley Trust will issue the capital securities under the
terms of the trust agreement. The trust agreement is qualified under the Trust
Indenture Act. The Bank of New York will act as the property trustee for
purposes of complying with the Trust Indenture Act. The terms of the capital
securities will include those stated in the trust agreement and the Delaware
Statutory Trust Act and those made part of the trust agreement by the Trust
Indenture Act.

General

         The capital securities will be limited to $750,000,000 aggregate
liquidation amount outstanding, or $862,500,000 aggregate liquidation amount
if the underwriters purchase all the additional capital securities they are
entitled to purchase pursuant to their over-allotment option. The capital
securities will rank equal to, and payments will be made on the capital
securities on a proportional basis with, the common securities. However, the
capital securities will rank prior to the common securities as to payment if
there occurs with respect to the junior subordinated debentures an event of
default or a default as a result of a failure to pay amounts under the junior
subordinated debentures when due as described under "Description of Capital
Securities--Subordination of Common Securities" on page 9 of the accompanying
prospectus. The trust agreement does not permit Morgan Stanley Trust to issue
any securities other than the common securities and the capital securities or
to incur any indebtedness.

         Morgan Stanley will register the junior subordinated debentures in
the name of Morgan Stanley Capital Trust VI. The property trustee will hold
the junior subordinated debentures in trust for the benefit of the holders of
the capital securities and the common securities.

Distributions

         Distributions on the capital securities will be fixed at an annual
rate of 6.60% of the stated liquidation amount of $25 per capital security,
payable quarterly in arrears on February 1, May 1, August 1 and November 1 of
each year, beginning May 1, 2006. If Morgan Stanley Trust is dissolved and its
assets distributed, for each capital security you own, you are entitled to
receive the liquidation amount (which may be paid in the form of a
distribution of a like amount of junior subordinated debentures) of $25 plus
accumulated but unpaid distributions from the assets of Morgan Stanley Trust
available for distribution, after it has paid or made reasonable provision to
pay, in accordance with Section 3808(e) of the Delaware Statutory Trust Act,
liabilities owed to its creditors. See "--Liquidation Distribution upon
Dissolution." Distributions to which holders of the capital securities are
entitled and that are past due will accumulate additional distributions at an
annual rate of 6.60% of the unpaid distributions, compounded quarterly. The
term "distribution" includes any additional distributions payable unless
otherwise stated.

         The amount of distributions payable for any period less than a full
distribution period will be computed on the basis of a 360-day year of twelve
30-day months and the actual number of days elapsed in a partial month in that
period. Distributions on the capital securities will accumulate from and
including the most recent distribution payment date to which distributions
have been paid or duly provided for, or, if no distributions have been paid or
duly provided for, from and including January 26, 2006 until, but excluding
the date the liquidation



                                     S-16


amount has been paid or duly made available for payment. The amount of
distributions payable for any full distribution period will be computed by
dividing the rate per annum by four.

         Distributions on the capital securities:

         o    will be cumulative;

         o    will accumulate from and including January 26, 2006, the date of
              initial issuance of the capital securities; and

         o    will be payable quarterly in arrears on February 1, May 1,
              August 1 and November 1 of each year, beginning May 1, 2006 and
              will be payable to the holder of record, as described below.

         Funds available for distribution will be limited to payments received
from Morgan Stanley on the junior subordinated debentures.

Payment of Distributions

         Morgan Stanley Trust will pay distributions on the capital securities
to DTC, which will credit the relevant accounts at DTC on the applicable
payment dates, or if DTC does not then hold the capital securities, Morgan
Stanley Trust will make the payments by check mailed to the addresses of the
holders as such addresses appear on the books and records of Morgan Stanley
Trust on the relevant record dates. However, a holder of $1 million or more in
aggregate liquidation amount of capital securities may receive distribution
payments, other than distributions payable at maturity, by wire transfer of
immediately available funds upon written request to the property trustee, in
its capacity as securities registrar under the trust agreement, not later than
15 calendar days prior to the date on which the distribution is payable. The
record dates will be the 15th calendar day, whether or not a business day,
before the relevant payment date.

         Morgan Stanley Trust will pay distributions through the property
trustee. The property trustee will hold amounts received from the junior
subordinated debentures in the payment account for the benefit of the holders
of the capital securities and the common securities.

         If a distribution is payable on a day that is not a business day,
then that distribution will be paid on the next day that is a business day,
and without any interest or other payment for any delay, with the same force
and effect as if made on the payment date.

         A business day is a day other than (a) a Saturday or Sunday, and (b)
a day on which banking institutions in The City of New York, New York are
authorized or required by law or executive order to close.

Deferral of Distributions

         As long as there is no event of default under the junior subordinated
debentures, Morgan Stanley has the right to defer payments of interest on the
junior subordinated debentures at any time and from time to time by extending
the interest payment period for a period (an "extension period") of up to 20
consecutive quarters, but not beyond the maturity of the junior subordinated
debentures.

         As a consequence, during an extension period, Morgan Stanley Trust
will defer payment of the quarterly distributions on the capital securities.
The accumulated but unpaid distributions will continue to accumulate
additional distributions, as permitted by applicable law, at an annual rate of
6.60%, compounded quarterly, during the extension period.


                                     S-17


         While Morgan Stanley defers interest payments on the junior
subordinated debentures, it will be restricted from (a) declaring or paying
any dividends or distributions on, or redeeming, purchasing, acquiring or
making a liquidation payment on, any shares of its capital stock and (b)
making payments on or repaying, repurchasing or redeeming any of its debt
securities that rank equal or junior to the junior subordinated debentures.
See "Description of Junior Subordinated Debentures--Option to Extend Interest
Payment Period" and "--Restrictions on Certain Payments; Certain Covenants of
Morgan Stanley" on pages S-27 and S-28, respectively, for more information
regarding these restrictions and the applicable exceptions.

         If Morgan Stanley Trust defers distributions, the deferred
distributions, including accumulated additional distributions, will be paid on
the distribution payment date following the last day of the extension period
to the holders on the record date for that distribution payment date. Upon
termination of an extension period and payment of all amounts due on the
capital securities, Morgan Stanley may elect to begin a new extension period,
subject to the above conditions.

         Morgan Stanley has no current intention of deferring payments of
interest by extending the interest payment period on the junior subordinated
debentures.

Redemption

         When Morgan Stanley repays or redeems the junior subordinated
debentures, whether at maturity or upon earlier redemption, the property
trustee will apply the proceeds from the repayment or redemption to redeem
capital securities and common securities having an aggregate liquidation
amount equal to that portion of the principal amount of junior subordinated
debentures being repaid or redeemed. The redemption price per security will
equal the $25 liquidation amount, plus accumulated but unpaid distributions to
but excluding the redemption date. Early redemption of the junior subordinated
debentures may require regulatory approval.

         If less than all of the junior subordinated debentures are to be
repaid or redeemed, then the aggregate liquidation amount of the capital
securities and the common securities to be redeemed will be allocated
approximately 3% to the common securities and 97% to the capital securities,
except in the case of an event of default or a default under the junior
subordinated debentures as a result of any failure by Morgan Stanley to pay
any amounts under the junior subordinated debentures when due. See
"Description of Capital Securities--Subordination of Common Securities" on
page 9 of the accompanying prospectus.

         Subject to obtaining any then required regulatory approval, Morgan
Stanley will have the right to redeem the junior subordinated debentures:

         o    on or after February 1, 2011, in whole or in part, on one or
              more occasions, at any time; and

         o    before February 1, 2011, in whole, but not in part, at any time
              within 90 days following the occurrence and continuation of a
              tax event or an investment company event, each as defined below.

         Morgan Stanley will also have the right to redeem the junior
subordinated debentures at any time, in whole or in part, in certain
circumstances upon the determination, based on the opinion of counsel
experienced in such matters, who may be an employee of Morgan Stanley or any
of its affiliates, that as a result of:

         o    any amendment to, clarification of or change (including any
              announced prospective change) in applicable laws or regulations
              or official interpretations thereof or policies with respect
              thereto or

         o    any official administrative pronouncement or judicial decision
              interpreting or applying such laws or regulations,


                                     S-18


which amendment, clarification, change, pronouncement or decision is effective
or announced on or after the date of this prospectus supplement, there is more
than an insubstantial risk that the capital securities will no longer
constitute allowable capital of Morgan Stanley or any holding company of which
Morgan Stanley is a subsidiary for the purposes of the capital adequacy
guidelines or policies of the SEC or any applicable regulatory body or
governmental authority.

         If then required under the rules and regulations of the SEC, Morgan
Stanley will obtain the prior approval of the SEC or such body or authority
before exercising its redemption rights described in this prospectus
supplement or the accompanying prospectus.

         A redemption of the junior subordinated debentures will cause a
mandatory redemption of the capital securities and the common securities. See
"Description of Junior Subordinated Debentures--Redemption" on page S-28.

         "Tax event" means the receipt by Morgan Stanley Trust of an opinion
of counsel experienced in such matters, who is not an officer or employee of
Morgan Stanley or any of its affiliates, to the effect that as a result of:

         o    any amendment to, or change, including any announced prospective
              change, in the laws, or any regulations thereunder, of the
              United States or any political subdivision thereof or taxing
              authority therein affecting taxation which is effective on or
              after the date of this prospectus supplement; or

         o    any official or administrative pronouncement or action or
              judicial decision interpreting or applying such laws or
              regulations which is announced on or after the date of this
              prospectus supplement;

there is more than an insubstantial risk that:

         (1)  Morgan Stanley Trust is, or will be within 90 days of the
              delivery of the opinion of counsel, subject to United States
              federal income tax with respect to income received or accrued on
              the junior subordinated debentures;

         (2)  interest payable by Morgan Stanley to Morgan Stanley Trust on
              the junior subordinated debentures is not, or will not be within
              90 days of the delivery of the opinion of counsel, deductible by
              Morgan Stanley, in whole or in part, for United States federal
              income tax purposes; or

         (3)  Morgan Stanley Trust is, or will be within 90 days of the
              delivery of the opinion of counsel, subject to more than a de
              minimis amount of taxes, duties or other governmental charges.

         If a tax event has occurred and is continuing and Morgan Stanley
Trust is the holder of all the junior subordinated debentures, Morgan Stanley
will pay any additional sums required so that distributions on the capital
securities will not be reduced by any additional taxes, duties or other
governmental charges payable by Morgan Stanley Trust as a result of the tax
event. See "Description of Junior Subordinated Debentures--Additional Sums" on
page S-28.

         "Investment company event" means the receipt by Morgan Stanley Trust
of an opinion of counsel experienced in such matters, who is not an officer or
employee of Morgan Stanley or any of its affiliates, to the effect that, as a
result of the occurrence of a change in law or regulation or a written change,
including any announced prospective change, in interpretation or application
of law or regulation by any legislative body, court, governmental agency or
regulatory authority, there is more than an insubstantial risk that Morgan
Stanley Trust is or will be considered an "investment company" that is
required to be registered under the Investment Company



                                     S-19


Act, which change or prospective change becomes effective or would become
effective, as the case may be, on or after the date of this prospectus
supplement.

Redemption Procedures

         Morgan Stanley Trust may redeem capital securities only in an amount
equal to the funds it has on hand and legally available to pay the redemption
price.

         The property trustee will mail written notice of the redemption of
the capital securities to the registered holders at least 30 but not more than
60 days before the date fixed for redemption. If Morgan Stanley Trust gives a
notice of redemption, then, by 12:00 noon, New York City time, on the date of
redemption, if the funds are available for payment, the property trustee will,
for capital securities held in book-entry form:

         o    irrevocably deposit with DTC funds sufficient to pay the
              applicable redemption price; and

         o    give DTC irrevocable instructions and authority to pay the
              redemption price to the holders of the capital securities.

         With respect to capital securities not held in book-entry form, if
funds are available for payment, the property trustee will:

         o    irrevocably deposit with the paying agent funds sufficient to
              pay the applicable redemption price; and

         o    give the paying agent irrevocable instructions and authority to
              pay the redemption price to the holders of capital securities
              upon surrender of their certificates evidencing the capital
              securities.

         Notwithstanding the above, distributions payable on or prior to the
date of redemption for any capital securities called for redemption will be
payable to the holders of the capital securities on the relevant record dates.

         Once notice of redemption is given and funds are deposited, then all
rights of the holders of the capital securities called for redemption will
terminate, except the right to receive the redemption price, but without any
interest or other payment for any delay in receiving it. If notice of
redemption is given and funds deposited as required, the capital securities
then will cease to be outstanding.

         If any date fixed for redemption is not a business day, then payment
of the redemption price will be made on the next day that is a business day,
without any interest or other payment for the delay.

         If payment of the redemption price for the capital securities called
for redemption is improperly withheld or refused and not paid either by Morgan
Stanley Trust or by Morgan Stanley under the guarantee, then distributions on
those capital securities will continue to accumulate at the then applicable
rate, from and including the date of redemption to but excluding the date of
actual payment. In this case, the actual payment date will be the date fixed
for redemption for purposes of calculating the redemption price.

         Subject to the above and applicable law, including United States
federal securities laws, Morgan Stanley or its affiliates may at any time and
from time to time purchase outstanding capital securities by tender, in the
open market or by private agreement, and may resell capital securities.

         If less than all the capital securities and common securities are
redeemed, then the aggregate liquidation amount of the capital securities and
the common securities to be redeemed normally will be allocated approximately
3% to the common securities and 97% to the capital securities. However, if
there has occurred



                                     S-20


with respect to the junior subordinated debentures an event of default or a
default as a result of any failure by Morgan Stanley to pay any amounts under
the junior subordinated debentures when due, holders of the capital securities
will be paid in full before any payments are made to holders of the common
securities. See "Description of Capital Securities--Subordination of Common
Securities" on page 9 of the accompanying prospectus for a more complete
discussion. The property trustee will select the particular capital securities
to be redeemed on the pro rata basis described above not more than 60 days
prior to the date of redemption by any method the property trustee deems fair
and appropriate or, if the capital securities are then held in book-entry
form, in accordance with DTC's customary procedures.

Liquidation Distribution upon Dissolution

         The amount payable on the capital securities in the event of any
liquidation of Morgan Stanley Trust is the liquidation amount of $25 per
capital security plus accumulated but unpaid distributions, subject to certain
exceptions, which may be paid in the form of a distribution of junior
subordinated debentures.

         Morgan Stanley can at any time dissolve Morgan Stanley Trust, subject
to obtaining any then required regulatory approval. If Morgan Stanley Trust
dissolves and it has paid or made reasonable provision to pay, in accordance
with Section 3808(e) of the Delaware Statutory Trust Act, the liabilities owed
to its creditors, the junior subordinated debentures may be distributed to the
holders of the capital securities and common securities.

         The trust agreement states that Morgan Stanley Trust will dissolve
automatically on February 1, 2046 or earlier upon:

         (1)  the bankruptcy, dissolution or liquidation of Morgan Stanley;

         (2)  written direction by Morgan Stanley to the property trustee to
              dissolve Morgan Stanley Trust and distribute junior subordinated
              debentures to the holders of the capital securities, which
              direction, subject to the foregoing restrictions, is optional
              and wholly within the discretion of Morgan Stanley;

         (3)  the redemption of all the capital securities in connection with
              the redemption of all the junior subordinated debentures or the
              maturity of the junior subordinated debentures; or

         (4)  the entry of an order for the dissolution of Morgan Stanley
              Trust by a court of competent jurisdiction.

         If Morgan Stanley Trust dissolves as described in clauses (1), (2) or
(4) above, after Morgan Stanley Trust pays all amounts owed to creditors,
holders of the capital securities and the common securities will be entitled
to receive:

         o    junior subordinated debentures having a principal amount equal
              to the liquidation amount of the capital securities and the
              common securities of the holders; or, if this is not practical,

         o    a cash amount equal to, in the case of holders of capital
              securities, the aggregate liquidation amount plus accumulated
              but unpaid distributions to but excluding the date of payment.

         If Morgan Stanley Trust cannot pay the full amount due on the capital
securities and the common securities because it has insufficient assets for
payment, then the amounts Morgan Stanley Trust owes on the capital securities
will be proportionately allocated. The holders of the common securities will
be entitled to receive distributions upon any liquidation on a pro rata basis
with the holders of the capital securities, except that if there occurs with
respect to the junior subordinated debentures an event of default or a default
as a result of a failure by Morgan Stanley to pay any amounts in respect of
the junior subordinated debentures when due, Morgan



                                     S-21


Stanley Trust will pay the total amounts due on the capital securities before
making any distribution on the common securities. See "Description of Capital
Securities--Subordination of Common Securities" on page 9 of the accompanying
prospectus.

         After the liquidation date is fixed for any distribution of junior
subordinated debentures, upon dissolution of Morgan Stanley Trust:

         o    the capital securities and the common securities will no longer
              be deemed to be outstanding;

         o    DTC or its nominee, as the registered holder of capital
              securities, will receive a registered global certificate or
              certificates representing the junior subordinated debentures to
              be delivered upon distribution with respect to capital
              securities held by DTC or its nominee; and

         o    any certificates representing capital securities not held by DTC
              or its nominee will be deemed to represent junior subordinated
              debentures having an aggregate principal amount equal to the
              liquidation amount of the capital securities, and bearing
              accrued but unpaid interest equal to accumulated but unpaid
              distributions on the capital securities, until the holder of
              those certificates presents them to the securities registrar for
              the capital securities for transfer or reissuance.

Capital Securities Events of Default

         For a description of events that constitute an event of default under
the trust agreement, see "Description of Capital Securities--Capital
Securities Events of Default; Notice" beginning on page 9 of the accompanying
prospectus.

The Capital Securities Will Initially Be Issued in Book-Entry Form and Held
Through DTC

         DTC will act as securities depositary for the capital securities.
Morgan Stanley Trust will issue one or more fully registered global securities
certificates in the name of DTC's nominee, Cede & Co. These certificates will
represent the total aggregate number of capital securities. Morgan Stanley
Trust will deposit these certificates with DTC or a custodian appointed by
DTC. Morgan Stanley Trust will not issue certificates to you for the capital
securities that you purchase, unless DTC's services are discontinued as
described below.

         Book-entry interests in the securities may be transferred within DTC
in accordance with procedures established for this purpose by DTC. Each person
owning a beneficial interest in the capital securities must rely on the
procedures of DTC and the participant through which such person owns its
interest to exercise its rights as a holder of the capital securities.

         DTC has provided Morgan Stanley Trust and Morgan Stanley with the
following information: DTC is a limited-purpose trust company organized under
the New York Banking Law, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code and a
"clearing agency" registered under the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). DTC holds
securities that its participants ("Direct Participants") deposit with DTC. DTC
also facilitates the settlement among Direct Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Direct Participants' accounts,
thereby eliminating the need for physical movement of securities certificates.
Direct Participants include securities brokers and dealers, banks, trust
companies, clearing corporations, and certain other organizations. DTC is
owned by a number of its Direct Participants and by the New York Stock
Exchange, Inc., the American Stock Exchange LLC, and the National Association
of Securities Dealers, Inc. Access to the DTC system is also available to
others such as securities brokers and dealers, banks and trust companies that
clear through or maintain




                                     S-22


a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to DTC and its
Direct and Indirect Participants are on file with the SEC.

         When you purchase capital securities within the DTC system, the
purchase must be made by or through a Direct Participant. The Direct
Participant will receive a credit for the capital securities on DTC's records.
You, as the actual owner of the capital securities, are the "beneficial
owner." Your beneficial ownership interest will be recorded on the Direct and
Indirect Participants' records, but DTC will have no knowledge of your
individual ownership. DTC's records reflect only the identity of the Direct
Participants to whose accounts capital securities are credited.

         You will not receive written confirmation from DTC of your purchase.
The Direct or Indirect Participants through whom you purchased the capital
securities should send you written confirmations providing details of your
transactions, as well as periodic statements of your holdings. The Direct and
Indirect Participants are responsible for keeping accurate account of the
holdings of their customers like you.

         Transfers of ownership interests held through Direct and Indirect
Participants will be accomplished by entries on the books of Direct and
Indirect Participants acting on behalf of the beneficial owners.

         The laws of some states may require that specified purchasers of
securities take physical delivery of the capital securities in definitive
form. These laws may impair the ability to transfer beneficial interests in
the global certificates representing the capital securities.

         Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to beneficial owners will be governed
by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

         Morgan Stanley Trust and Morgan Stanley understand that, under DTC's
existing practices, in the event that Morgan Stanley Trust or Morgan Stanley
requests any action of holders, or an owner of a beneficial interest in a
global security such as you desires to take any action which a holder is
entitled to take under the trust agreement or the junior subordinated
debentures, DTC would authorize the Direct Participants holding the relevant
beneficial interests to take such action, and those Direct Participants and
any Indirect Participants would authorize beneficial owners owning through
those Direct and Indirect Participants to take such action or would otherwise
act upon the instructions of beneficial owners owning through them.

         The property trustee, on behalf of Morgan Stanley Trust, will send
redemption notices to Cede & Co. If less than all of the capital securities
are being redeemed, DTC will reduce each Direct Participant's holdings of
capital securities in accordance with its procedures.

         In those instances where a vote is required, neither DTC nor Cede &
Co. itself will consent or vote with respect to capital securities. Under its
usual procedures, DTC would mail an omnibus proxy to Morgan Stanley Trust as
soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s
consenting or voting rights to those Direct Participants to whose accounts the
capital securities are credited on the record date, which are identified in a
listing attached to the omnibus proxy.

         The property trustee, on behalf of Morgan Stanley Trust, will make
distributions on the capital securities directly to DTC. DTC's practice is to
credit participants' accounts on the relevant payment date in accordance with
their respective holdings shown on DTC's records unless DTC has reason to
believe that it will not receive payment on that payment date.



                                     S-23


         Payments by Direct and Indirect Participants to beneficial owners
such as you will be governed by standing instructions and customary practices,
as is the case with securities held for the accounts of customers in bearer
form or registered in "street name." These payments will be the responsibility
of the participant and not of DTC, Morgan Stanley, Morgan Stanley Trust, the
trustees, the paying agent or any other agent of Morgan Stanley or Morgan
Stanley Trust.

         DTC may discontinue providing its services as securities depositary
with respect to the capital securities at any time by giving reasonable notice
to Morgan Stanley Trust. Additionally, Morgan Stanley may decide to
discontinue the book-entry only system of transfers with respect to the
capital securities. In that event, Morgan Stanley Trust will print and deliver
certificates in fully registered form for the capital securities. If DTC
notifies Morgan Stanley Trust that it is unwilling to continue as securities
depositary, or if it is unable to continue or ceases to be a clearing agency
registered under the Exchange Act and a successor depositary is not appointed
by Morgan Stanley Trust within ninety days after receiving such notice or
becoming aware that DTC is no longer so registered, Morgan Stanley Trust will
issue the capital securities in definitive form, at its expense, upon
registration of transfer of, or in exchange for, such global security.

         According to DTC, the foregoing information with respect to DTC has
been provided to the financial community for informational purposes only and
is not intended to serve as a representation, warranty or contract
modification of any kind.

         Morgan Stanley Trust and Morgan Stanley obtained the information in
this section concerning DTC and DTC's book-entry system from sources that
Morgan Stanley Trust and Morgan Stanley believe to be reliable, but take no
responsibility for the accuracy of the information. DTC may change or
discontinue the foregoing procedures at any time.

                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES

         The following, together with the description applicable to junior
subordinated debt securities under "Description of Junior Subordinated
Debentures" beginning on page 14 of the accompanying prospectus, describes
material terms of the junior subordinated debentures. You should also read the
junior subordinated debt indenture, dated as of October 1, 2004, between
Morgan Stanley and The Bank of New York, as indenture trustee, and the Trust
Indenture Act. The junior subordinated debt indenture is on file at the SEC as
an exhibit to the registration statement pertaining to this prospectus
supplement and the accompanying prospectus.

         Under circumstances involving the dissolution of Morgan Stanley
Trust, Morgan Stanley Trust may distribute the junior subordinated debentures
to the holders of the capital securities and the common securities in
liquidation of Morgan Stanley Trust. See "Description of Capital
Securities--Liquidation Distribution upon Dissolution" beginning on page S-21.
If the junior subordinated debentures are distributed to the holders of
capital securities, Morgan Stanley will use its reasonable best efforts to
have the junior subordinated debentures listed on the New York Stock Exchange
or with another organization on which the capital securities are then listed.

General

         The junior subordinated debentures are unsecured, subordinated
obligations of Morgan Stanley. The junior subordinated debentures to be
acquired by Morgan Stanley Trust will be limited in aggregate principal amount
to $773,195,900 or $889,175,275 aggregate principal amount if the underwriters
purchase all the additional capital securities they are entitled to purchase
pursuant to their over-allotment option. The amount will be limited to the sum
of:

         o    the aggregate stated liquidation amount of the capital
              securities issued by Morgan Stanley Trust; and

         o    the amount of capital contributed by Morgan Stanley to Morgan
              Stanley Trust in exchange for the common securities.

         The junior subordinated debentures and related guarantees will rank
subordinate and junior in right of payment to all of Morgan Stanley's current
and future senior indebtedness, liabilities and obligations, including senior
subordinated debt of Morgan Stanley and obligations of Morgan Stanley in
respect of interest rate, foreign exchange rate and commodity forward
contracts, options and swaps and similar arrangements. For information on the
subordination of the junior subordinated debentures, see "Subordination" on
page S-26 and "Description of Junior Subordinated Debentures" beginning on
page 14 of the accompanying prospectus.

         The entire principal amount of the junior subordinated debentures
will become due and payable, with any accrued and unpaid interest thereon, on
February 1, 2046.

         The provisions of the junior subordinated debt indenture described in
the accompanying prospectus relating to discharge, defeasance and covenant
defeasance will not apply to the junior subordinated debentures. See
"Description of Junior Subordinated Debentures--Discharge, Defeasance and
Covenant Defeasance" beginning on page 20 of the accompanying prospectus.

Interest

         The junior subordinated debentures will bear interest at an annual
rate of 6.60%. Interest on the junior subordinated debentures will accrue from
and including the most recent interest payment date to which interest has been
paid or duly provided for, or, if no interest has been paid or duly provided
for, from and including




                                     S-25


January 26, 2006 until, but excluding the date the principal has been paid or
duly made available for payment. Interest is payable quarterly in arrears on
February 1, May 1, August 1 and November 1 of each year, beginning May 1,
2006. Interest payments not paid when due will accrue, as permitted by
applicable law, additional interest, compounded quarterly, at the annual rate
of 6.60%. Morgan Stanley will pay interest on the junior subordinated
debentures to holders as they appear on the books and records of the property
trustee on the relevant record date. The record date will be 15 calendar days,
whether or not a business day, before the relevant payment date.

         The amount of interest payable for any period less than a full
interest period will be computed on the basis of a 360-day year of twelve
30-day months and the actual days elapsed in a partial month in that period.
The amount of interest payable for any full interest period will be computed
by dividing the rate per annum by four.

         If any date on which interest is payable on the junior subordinated
debentures is not a business day, then payment of the interest payable on that
date will be made on the next succeeding day that is a business day, without
any interest or other payment in respect of the delay, with the same force and
effect as if made on the date that payment was originally payable. Accrued
interest that is not paid on the applicable interest payment date will bear
additional interest at the rate per annum of 6.60%, compounded quarterly and
computed on the basis of a 360-day year of twelve 30-day months and the actual
number of days elapsed in a partial month in such period. The amount of
additional interest payable for any full interest period will be computed by
dividing the rate per annum by four. The term "interest" as used in this
prospectus supplement and the accompanying prospectus includes quarterly
interest payments, interest on quarterly interest payments not paid on the
applicable interest payment date, compounded interest and additional sums, as
applicable.

         The interest payment provisions for the junior subordinated
debentures correspond to the distribution provisions for the capital
securities. See "Description of Capital Securities--Distributions" beginning
on page S-16.

Subordination

         Holders of the junior subordinated debentures should recognize that
contractual provisions in the indenture may prohibit Morgan Stanley from
making payments on these securities. The junior subordinated debentures are
subordinate and junior in right of payment, to the extent and in the manner
stated in the indenture and the junior subordinated debentures, to all of
Morgan Stanley's senior indebtedness.

         For purposes of the junior subordinated debentures, senior
indebtedness shall include (i) obligations of, or guaranteed or assumed by,
Morgan Stanley for borrowed money or evidenced by bonds, debentures, notes or
similar instruments, including obligations with respect to securities issued
under Morgan Stanley's senior indentures or senior subordinated indentures,
and amendments, renewals, extensions, modifications and refundings of any of
that indebtedness or of those obligations, (ii) capitalized lease obligations
of Morgan Stanley, (iii) obligations of Morgan Stanley issued or assumed as
the deferred purchase price of property, (iv) obligations of Morgan Stanley in
respect of interest rate, foreign exchange rate and commodity forward
contracts, options and swaps and similar arrangements and (v) all obligations
of the type referred to in clauses (i) through (iv) of other persons which
Morgan Stanley has guaranteed or is responsible or liable for as obligor or
otherwise. The junior subordinated debentures and related guarantees will rank
equally with the junior subordinated debt of Morgan Stanley underlying the
existing capital securities of the Existing Morgan Stanley Trusts and
guarantees by Morgan Stanley of the capital securities issued by the Existing
Morgan Stanley Trusts, respectively. Because the definition of senior
indebtedness that applies to the junior subordinated debentures is broader
than the definition of senior indebtedness that applies to the existing junior
subordinated debentures, the right to payment under the



                                     S-26


junior subordinated debentures described in this prospectus supplement upon
Morgan Stanley's bankruptcy or insolvency may be more limited than under the
existing junior subordinated debentures.

Option to Extend Interest Payment Period

         As long as no event of default has occurred under the indenture,
Morgan Stanley has the right, at any time and from time to time, to defer
payments of interest for a period (an "extension period") of up to 20
consecutive quarters, but not beyond the maturity date of the junior
subordinated debentures. During an extension period, interest will continue to
accrue and holders of junior subordinated debentures, or holders of capital
securities while outstanding, will be required to accrue interest income as
original issue discount for United States federal income tax purposes. See
"United States Federal Income Tax Consequences--U.S. Holders--Interest Income
and Original Issue Discount" beginning on page S-38 for further information on
United States federal income tax consequences. On the interest payment date
following the last day of any extension period, Morgan Stanley will pay all
interest then accrued and unpaid, together with additional interest on the
accrued and unpaid interest as permitted by law ("compounded interest"),
compounded quarterly, at the annual rate of 6.60% plus any additional sums, as
described below.

         During an extension period, Morgan Stanley is subject to
restrictions, as described below under "--Restrictions on Certain Payments;
Certain Covenants of Morgan Stanley."

         Before termination of any extension period, Morgan Stanley may
further extend the payments of interest. However, no extension period,
including all previous and further extensions, may exceed 20 consecutive
quarters or extend beyond the maturity of the junior subordinated debentures.
If any junior subordinated debentures are called for redemption before the end
of an extension period, the extension period will end on that redemption date
or an earlier date as determined by Morgan Stanley. After the termination of
any extension period and the payment of all amounts due, Morgan Stanley may
begin a new extension period, as described above. There is no limitation on
the number of times Morgan Stanley may elect to begin an extension period.
Interest will not be payable during an extension period, only at the end of
the extension period. Morgan Stanley may, however, prepay at any time all or
any portion of the interest accrued during an extension period.

         If the property trustee is the sole holder of the junior subordinated
debentures, Morgan Stanley will give the property trustee and the Delaware
trustee written notice of its selection of an extension period at least 15
business days before the next succeeding date on which the distributions on
the capital securities are payable. The property trustee will give notice of
Morgan Stanley's selection of an extension period to the holders of the
capital securities.

         If the property trustee is not the sole holder, or is not itself the
holder, of the junior subordinated debentures, Morgan Stanley will give the
holders of the junior subordinated debentures and the property trustee written
notice of its selection of an extension period at least 10 business days
before the earlier of:

         o    the next interest payment date; and

         o    the date Morgan Stanley is required to give notice to holders of
              the junior subordinated debentures of the record or payment date
              for the related interest payment.

         Morgan Stanley has no present intention of exercising its right to
defer payments of interest by extending the interest payment period on the
junior subordinated debentures.



                                     S-27


Additional Sums

         If, at any time while the property trustee is the holder of the
junior subordinated debentures, Morgan Stanley Trust is required to pay any
additional taxes, duties or other governmental charges as a result of a tax
event, Morgan Stanley will pay as additional interest on the junior
subordinated debentures any additional amounts ("additional sums") that are
required so that the distributions paid by Morgan Stanley Trust will not be
reduced as a result of any of those taxes, duties or governmental charges.

Redemption

         Subject to obtaining any then required regulatory approval, Morgan
Stanley has the right to redeem the junior subordinated debentures:

         o    on or after February 1, 2011, in whole or in part, on one or
              more occasions, at any time;

         o    before February 1, 2011, in whole, but not in part, at any time
              within 90 days following the occurrence and continuation of a
              tax event or an investment company event (the "90-day period"),
              as described under "Description of Capital
              Securities--Redemption" beginning on page S-18; and

         o    at any time, in whole or in part, upon receipt of an opinion of
              counsel regarding adverse changes in the policies or rules and
              regulations of the SEC or of any other applicable regulatory
              body or governmental authority relating to capital treatment, as
              described under "Description of Capital Securities--Redemption"
              beginning on page S-18.

         In any case, the redemption price will equal 100% of the principal
amount to be redeemed, plus any accrued and unpaid interest, including any
compounded interest and any additional sums, if any, to the date of
redemption.

         Morgan Stanley's right to redeem the junior subordinated debentures
due to a tax event or investment company event is subject to the condition
that, if Morgan Stanley or Morgan Stanley Trust has the opportunity to
eliminate, within the 90-day period, the tax event or investment company event
by taking some ministerial action that will have no adverse effect on Morgan
Stanley, Morgan Stanley Trust or the holders of the capital securities and the
common securities and will involve no material cost, Morgan Stanley will
pursue such measures in lieu of redemption. Morgan Stanley cannot redeem the
junior subordinated debentures while either it or Morgan Stanley Trust is
pursuing any ministerial action under the trust agreement as described above.

Restrictions on Certain Payments; Certain Covenants of Morgan Stanley

         Morgan Stanley will not:

         o    declare or pay any dividends or distributions on, or redeem,
              purchase, acquire or make a liquidation payment on, any of its
              capital stock; or

         o    make any payment of principal of or interest or premium, if any,
              on or repay, repurchase or redeem debt securities of Morgan
              Stanley that rank equal or junior to the junior subordinated
              debentures,

         if at such time:



                                     S-28


         o    there has occurred any event (1) of which Morgan Stanley has
              actual knowledge that with the giving of notice or the lapse of
              time, or both, would constitute a default under the junior
              subordinated debentures and (2) that Morgan Stanley has not
              taken reasonable steps to cure;

         o    the junior subordinated debentures are held by Morgan Stanley
              Trust and Morgan Stanley is in default with respect to its
              payment of any obligations under the guarantee; or

         o    Morgan Stanley has given notice of its election of an extension
              period and has not rescinded this notice, or the extension
              period, or any extension thereof, is continuing.

         The restrictions listed above do not apply to:

         o    repurchases, redemptions or other acquisitions of shares of
              capital stock of Morgan Stanley in connection with (1) any
              employment contract, benefit plan or other similar arrangement
              with or for the benefit of any one or more employees, officers,
              directors or consultants, (2) a dividend reinvestment or
              stockholder stock purchase plan, or (3) the issuance of capital
              stock of Morgan Stanley, or securities convertible into or
              exercisable for such capital stock, as consideration in an
              acquisition transaction entered into prior to the extension
              period;

         o    an exchange, redemption or conversion of any class or series of
              Morgan Stanley's capital stock, or any capital stock of a
              subsidiary of Morgan Stanley, for any class or series of Morgan
              Stanley's capital stock, or of any class or series of Morgan
              Stanley's indebtedness for any class or series of Morgan
              Stanley's capital stock;

         o    the purchase of fractional interests in shares of Morgan
              Stanley's capital stock under the conversion or exchange
              provisions of the capital stock or the security being converted
              or exchanged;

         o    any declaration of a dividend in connection with any
              stockholders' rights plan, or the issuance of rights, stock or
              other property under any stockholders' rights plan, or the
              redemption or repurchase of rights pursuant to the plan;

         o    payments by Morgan Stanley under the guarantee of the capital
              securities; or

         o    any dividend in the form of stock, warrants, options or other
              rights where the dividend stock or the stock issuable upon
              exercise of such warrants, options or other rights is the same
              stock as that on which the dividend is being paid or ranks equal
              or junior to that stock.

         In addition, as long as Morgan Stanley Trust holds any of the junior
subordinated debentures, Morgan Stanley agrees:

         o    to continue to hold, directly or indirectly, 100% of the common
              securities of Morgan Stanley Trust, provided that certain
              successors that are permitted under the junior subordinated debt
              indenture may succeed to Morgan Stanley's ownership of the
              common securities;

         o    as holder of the common securities, not to voluntarily dissolve,
              windup or liquidate Morgan Stanley Trust, other than (1) as part
              of the distribution of the junior subordinated debentures to the
              holders of the capital securities in accordance with the terms
              of the capital securities or (2) as part of a merger,
              consolidation or amalgamation which is permitted under the trust
              agreement; and


                                     S-29


         o    to use its reasonable efforts, consistent with the terms and
              provisions of the trust agreement, to cause Morgan Stanley Trust
              to continue not to be taxable as a corporation for United States
              federal income tax purposes.

Registration, Denomination and Transfer

         Morgan Stanley will register the junior subordinated debentures in
the name of Morgan Stanley Trust. The property trustee will hold the junior
subordinated debentures in trust for the benefit of the holders of the capital
securities and the common securities. The junior subordinated debentures will
be issued in denominations of $25 and integral multiples thereof.

         If the junior subordinated debentures are distributed to holders of
capital securities, it is anticipated that DTC will act as securities
depositary for the junior subordinated debentures. For a description of DTC
and the specific terms of the depositary arrangements, see "Description of
Capital Securities--The Capital Securities Will Initially Be Issued in
Book-Entry Form and Held Through DTC" beginning on page S-22.

         As of the date of this prospectus supplement, the description of
DTC's book-entry system and DTC's practices as they relate to purchases of,
transfers of, notices concerning and payments on the capital securities apply
in all material respects to any debt obligations represented by one or more
global securities held by DTC.

         A global security will be exchangeable for junior subordinated
debentures registered in the names of persons other than DTC or its nominee
only if:

         o    DTC notifies Morgan Stanley that it is unwilling or unable to
              continue as a depositary for the global security and no
              successor depositary has been appointed;

         o    DTC ceases to be a clearing agency registered under the Exchange
              Act at a time DTC is required to be so registered to act as
              depositary, and no successor depositary has been appointed; or

         o    Morgan Stanley, in its sole discretion, determines that the
              global security shall be exchangeable for definitive
              certificates.

         Any global security that is exchangeable as described above will be
exchangeable for junior subordinated debentures registered in the names DTC
directs. Morgan Stanley expects that the instructions will be based upon
directions received by DTC from its Direct Participants with respect to
ownership of beneficial interests in the global security.

         If the junior subordinated debentures are issued in certificated
form, payments of principal and interest will be payable, the transfer of the
junior subordinated debentures will be registrable, and junior subordinated
debentures will be exchangeable for junior subordinated debentures of other
authorized denominations of a like aggregate principal amount. However,
payment of interest may be made at the option of Morgan Stanley by check
mailed to the address of the holder entitled to the payment. Upon written
request to the paying agent not less than 15 calendar days prior to the date
on which interest is payable, a holder of $1 million or more in aggregate
principal amount of junior subordinated debentures may receive payment of
interest, other than payments of interest payable at maturity or on any date
of redemption or repayment, by wire transfer of immediately available funds.

         Junior subordinated debentures may be presented for registration of
transfer, exchange, redemption or payment with an endorsed form of transfer,
or a duly executed and satisfactory written instrument of transfer, at the
securities registrar's office in New York, New York or the office of any
transfer agent selected by Morgan



                                     S-30


Stanley without service charge and upon payment of any taxes and other
governmental charges as described in the junior subordinated debt indenture.
Morgan Stanley will appoint the indenture trustee as securities registrar
under the junior subordinated debt indenture. Morgan Stanley may at any time
designate additional transfer and paying agents with respect to the junior
subordinated debentures.

         In the event of any redemption, Morgan Stanley and the indenture
trustee will not be required to:

         o    register the transfer of or exchange junior subordinated
              debentures during a period beginning 15 calendar days before the
              first mailing of the notice of redemption; or

         o    register the transfer of or exchange any junior subordinated
              debentures selected for redemption, except, in the case of any
              junior subordinated debentures being redeemed in part, any
              portion not to be redeemed.

         At the request of Morgan Stanley, funds deposited with the indenture
trustee or any paying agent held for Morgan Stanley for the payment of
principal, interest and premium, if any, on any junior subordinated debenture
which remain unclaimed for two years after the principal, interest and
premium, if any, has become payable will be repaid to Morgan Stanley and the
holder of the junior subordinated debenture will, as a general unsecured
creditor, look only to Morgan Stanley for payment thereof.

Modification of Indenture

         For a description of the provisions for modifying the junior
subordinated debt indenture and the junior subordinated debentures, see
"Description of Junior Subordinated Debentures--Modification of Indenture"
beginning on page 21 of the accompanying prospectus. In addition, if any of
the capital securities are outstanding:

         o    no modification may be made to the junior subordinated debt
              indenture that materially adversely affects the holders of the
              capital securities;

         o    no termination of the junior subordinated debt indenture may
              occur; and

         o    no waiver of any event of default or default under the junior
              subordinated debentures may be effective,

without the prior consent of the holders of at least a majority of the
aggregate liquidation amount of the outstanding capital securities unless and
until the principal of and premium, if any, on the junior subordinated
debentures and all accrued and unpaid interest thereon have been paid in full
and certain other conditions are satisfied.

         In addition, if any of the capital securities are outstanding, all
holders of the capital securities must consent if Morgan Stanley wants to
amend the junior subordinated debt indenture to:

         o    remove the rights of holders of capital securities to institute
              a direct action (as defined below);

         o    remove any obligation to obtain the consent of holders of
              capital securities; or

         o    change the percentage of holders of the capital securities
              required to amend or waive any provision of the junior
              subordinated debt indenture.


                                     S-31


         So long as Morgan Stanley complies with the terms of the junior
subordinated debentures and the junior subordinated debt indenture, Morgan
Stanley may defer interest payable on the junior subordinated debentures, as
described in this prospectus supplement, without the consent of Morgan Stanley
Trust or the holders of the capital securities.

Events of Default, Defaults and the Rights of Capital Securities Holders to
Take Action Against Morgan Stanley

See "Description of Junior Subordinated Debentures--Events of Default and
Defaults" beginning on page 18 of the accompanying prospectus for a
description of:

         o    the events of default and defaults for the junior subordinated
              debentures; and

         o    the actions that may be taken by the indenture trustee and the
              holders of junior subordinated debentures, including Morgan
              Stanley Trust, following an event of default or default,
              respectively.

         So long as Morgan Stanley Trust holds the junior subordinated
debentures, the property trustee and the holders of the capital securities
will have the following rights under the junior subordinated debt indenture
with respect to an event of default or a default:

         o    upon the occurrence of an event of default, the property trustee
              and the holders of not less than 25% in aggregate liquidation
              amount of the capital securities may declare the principal and
              interest accrued thereon of the junior subordinated debentures
              due and payable immediately;

         o    upon the occurrence of a default, there is no right of
              acceleration except for those defaults that are also events of
              default; if a default in the payment of principal of, or any
              interest on, any series of junior subordinated debentures issued
              under the indenture occurs and is continuing and Morgan Stanley
              fails to pay the full amount then due and payable with respect
              to the junior subordinated debentures immediately upon the
              demand of the indenture trustee, the indenture trustee is
              entitled to institute an action or proceeding to collect the
              amount due and unpaid; if any default occurs and is continuing,
              the indenture trustee may pursue legal action to enforce the
              performance of any provision in the indenture to protect the
              rights of the indenture trustee and the holders of the junior
              subordinated debentures;

         o    if all defaults have been cured or waived, the consent of the
              holders of more than 50% in aggregate liquidation amount of the
              capital securities is required to annul a declaration by the
              indenture trustee, Morgan Stanley Trust or the holders of the
              capital securities that the principal of the junior subordinated
              debentures is due and payable immediately;

         o    unless the default is cured, the consent of each holder of
              capital securities is required to waive a default in the payment
              of principal, premium or interest with respect to the junior
              subordinated debentures or a default in respect of a covenant or
              provision that cannot be modified or amended without the consent
              of the holder of each outstanding junior subordinated debenture;
              and

         o    unless the default is cured, the consent of the holders of more
              than 50% in aggregate liquidation amount of the capital
              securities is required to waive any other default.

         If the event of default or default under the junior subordinated
debentures is attributable to the failure of Morgan Stanley to pay any amounts
payable on the junior subordinated debentures when due, then a registered
holder of capital securities may bring a legal action against Morgan Stanley
directly for enforcement of payment



                                     S-32


to such holder of amounts owed on the junior subordinated debentures with a
principal amount equal to the aggregate liquidation amount of the capital
securities held by such holder (a "direct action"). Morgan Stanley may not
amend the junior subordinated debentures to remove this right to bring a
direct action without the prior written consent of the registered holders of
all the capital securities. Morgan Stanley can set-off against payments then
due under the junior subordinated debenture any corresponding payments made to
holders of capital securities by Morgan Stanley in connection with a direct
action.

         The holders of the capital securities will not be able to exercise
directly any remedies available to the holders of the junior subordinated
debentures except under the circumstance described in the preceding paragraph.
See "Description of Capital Securities--Capital Securities Events of Default;
Notice" beginning on page 9 of the accompanying prospectus.

                           DESCRIPTION OF GUARANTEE

         The following, together with the "Description of Guarantees"
beginning on page 24 of the accompanying prospectus, is a description of the
material terms of the guarantee. You should read the guarantee, to be dated as
of January 26, 2006, between Morgan Stanley and The Bank of New York, as
guarantee trustee, and the Trust Indenture Act. A form of guarantee is on file
at the SEC as an exhibit to the registration statement pertaining to this
prospectus supplement and the accompanying prospectus.

         The following payments on the capital securities (the "guarantee
payments"), if not fully paid by Morgan Stanley Trust, will be paid by Morgan
Stanley under the guarantee, without duplication:

         o    any accumulated and unpaid distributions required to be paid on
              the capital securities, to the extent Morgan Stanley Trust
              has funds available to make the payment;

         o    the redemption price for any capital securities called for
              redemption, if Morgan Stanley Trust has funds available to make
              the payment; and

         o    upon a voluntary or involuntary dissolution, winding-up or
              liquidation of Morgan Stanley Trust, other than in connection
              with a distribution of the junior subordinated debentures to the
              holders of capital securities, the lesser of:

                  (1)      the aggregate of the $25 per capital security
                           liquidation amount and all accumulated and unpaid
                           distributions on the capital securities to the date
                           of payment, if Morgan Stanley Trust has funds
                           available to make the payment; and

                  (2)      the amount of assets of Morgan Stanley Trust
                           remaining available for distribution to holders of
                           the capital securities upon liquidation of Morgan
                           Stanley Trust.

         Morgan Stanley's obligation to make a guarantee payment may be
satisfied by direct payment of the required amounts by Morgan Stanley to the
holders of the capital securities or by causing Morgan Stanley Trust to pay
the amounts to the holders.




                                     S-34



                  RELATIONSHIP AMONG THE CAPITAL SECURITIES,
             THE JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEE

         Morgan Stanley will guarantee payments of distributions and
redemption and liquidation payments due on the capital securities to the
extent Morgan Stanley Trust has funds available for such payment, as described
under "Description of Guarantee" above. No single document executed by Morgan
Stanley will provide for the full, irrevocable and unconditional guarantee of
the capital securities. It is only the combined operation of the guarantee,
the trust agreement and the junior subordinated debt indenture that has the
effect of providing a full, irrevocable and unconditional guarantee of Morgan
Stanley Trust's obligations under the capital securities.

         As long as Morgan Stanley pays interest and other payments when due
on the junior subordinated debentures, those payments will be sufficient to
cover distributions and redemption and liquidation payments due on the capital
securities, primarily because:

         o    the aggregate principal amount of the junior subordinated
              debentures will be equal to the sum of the aggregate liquidation
              amount of the capital securities and the common securities;

         o    the interest rate and interest and other payment dates on the
              junior subordinated debentures will match the distribution rate
              and distribution and other payment dates for the capital
              securities;

         o    Morgan Stanley will pay for any and all costs, expenses and
              liabilities of Morgan Stanley Trust, except withholding taxes
              and Morgan Stanley Trust's obligations to holders of the capital
              securities and the common securities; and

         o    the trust agreement provides that Morgan Stanley Trust will not
              engage in any activity that is not consistent with the limited
              purposes of Morgan Stanley Trust.

         A default or event of default under any senior indebtedness of Morgan
Stanley would not necessarily constitute a default or event of default under
the capital securities. However, in the event of payment defaults under, or
acceleration of, senior indebtedness of Morgan Stanley, the junior
subordinated debt indenture provides that no payments may be made on the
junior subordinated debentures until the senior indebtedness has been paid in
full or any payment default under the senior indebtedness has been cured or
waived. See "Description of Junior Subordinated Debentures" beginning on page
14 of the accompanying prospectus.

Limited Purpose of Morgan Stanley Trust

         The capital securities represent preferred undivided beneficial
interests in the assets of Morgan Stanley Trust. Morgan Stanley Trust exists
for the sole purpose of:

         o    issuing and selling the capital securities and common securities;

         o    investing the proceeds from the sale of the capital securities
              and common securities in the junior subordinated debentures;
              and

         o    engaging in only those other activities necessary, convenient
              or incidental to these purposes.

         A principal difference between the rights of a holder of a capital
security and a holder of a junior subordinated debenture is that a holder of a
junior subordinated debenture is entitled to receive from Morgan Stanley
payments on junior subordinated debentures held by the holder, while a holder
of capital securities is entitled to receive distributions or other amounts
payable with respect to the capital securities from Morgan



                                     S-35


Stanley Trust or from Morgan Stanley under the guarantee only if and to the
extent Morgan Stanley Trust has funds available for the payment of those
distributions.

Rights upon Dissolution

         The holders of the capital securities are entitled to receive, out of
assets held by Morgan Stanley Trust, a distribution in cash upon any voluntary
or involuntary dissolution, winding-up or liquidation of Morgan Stanley Trust
that does not involve the distribution of the junior subordinated debentures,
after Morgan Stanley Trust has paid or made reasonable provision to pay, in
accordance with Section 3808(e) of the Delaware Statutory Trust Act, the
liabilities owed to its creditors as required by applicable law. See
"Description of Capital Securities--Liquidation Distribution upon Dissolution"
beginning on page S-21.

         In the event of any voluntary or involuntary liquidation or
bankruptcy of Morgan Stanley, Morgan Stanley Trust, as registered holder of
the junior subordinated debentures, would be a subordinated creditor of Morgan
Stanley, subordinated and junior in right of payment to all Morgan Stanley's
senior indebtedness, but entitled to receive payment in full of all amounts
payable with respect to the junior subordinated debentures before any
stockholders of Morgan Stanley receive payments or distributions. Since Morgan
Stanley is the guarantor under the guarantee and has agreed to pay for all
costs, expenses and liabilities of Morgan Stanley Trust (other than
withholding taxes and Morgan Stanley Trust's obligations to the holders of the
capital securities and common securities), the positions of a holder of the
capital securities and a holder of the junior subordinated debentures relative
to other creditors and to stockholders of Morgan Stanley in the event of
liquidation or bankruptcy of Morgan Stanley are expected to be substantially
the same.

                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

General

         In the opinion of Sidley Austin LLP, tax counsel to Morgan Stanley
and Morgan Stanley Trust, the following discussion summarizes the material
United States federal income tax consequences of the purchase, ownership and
disposition of the capital securities.

         This summary is based on the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury regulations under the Code, and administrative
and judicial interpretations thereof, each as of the date of this prospectus
supplement, all of which are subject to change, possibly on a retroactive
basis. The authorities on which this summary is based are subject to various
interpretations, and this summary is not binding on the Internal Revenue
Service ("IRS") or the courts, either of which could take a contrary position.
Moreover, no rulings have been or will be sought from the IRS with respect to
the transactions described in this prospectus supplement. Accordingly, there
can be no assurance that the IRS will not challenge the opinions expressed in
this tax section or that a court would not sustain such a challenge.

         Except as otherwise stated, this summary deals only with capital
securities held as capital assets by a holder who or which (i) purchased the
capital securities upon original issuance (an "Initial Holder") at the price
to the public and (ii) is a U.S. Holder (as defined below). This summary does
not address all the tax consequences that may be relevant to a U.S. Holder,
nor does it address the tax consequences, except as stated below, to holders
that are not U.S. Holders ("Non-U.S. Holders") or to holders that may be
subject to special tax treatment (such as banks, thrift institutions, real
estate investment trusts, regulated investment companies, insurance companies,
brokers and dealers in securities or currencies, other financial institutions,
tax-exempt organizations, persons holding the capital securities as a position
in a "straddle," as part of a "synthetic security," "hedging," "conversion" or
other integrated investment, persons having a functional currency other than
the U.S. Dollar and certain United States expatriates). Further, this summary
does not address

         (a)  the income tax consequences to shareholders in, or partners or
              beneficiaries of, a holder of the capital securities,

         (b)  the United States federal alternative minimum tax consequences
              of the purchase, ownership or disposition of the capital
              securities, or

         (c)  any state, local or foreign tax consequences of the purchase,
              ownership and disposition of capital securities.

         A "U.S. Holder" is a holder of the capital securities who or which
for United States federal income tax purposes is

         o    a citizen or resident of the United States,

         o    a corporation or partnership (including an entity treated as a
              corporation or partnership for United States federal income tax
              purposes) created or organized in or under the laws of the
              United States, any state thereof or the District of Columbia
              (other than a partnership that is not treated as a United States
              person under any applicable Treasury regulations),

         o    an estate whose income is subject to United States federal
              income tax regardless of its source, or



                                     S-37


         o    a trust if (a) a court within the United States is able to
              exercise primary supervision over the administration of the
              trust and (b) one or more United States persons have the
              authority to control all substantial decisions of the trust.
              Notwithstanding the above, to the extent provided in Treasury
              regulations, certain trusts in existence on August 20, 1996 and
              treated as United States persons prior to such date that elect
              to continue to be treated as United States persons will also be
              U.S. Holders.

         HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE CAPITAL
SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND
OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR
OTHER TAX LAWS.

U.S. Holders

         Characterization of Morgan Stanley Trust. Under current law and based
on the representations, facts and assumptions set forth in this prospectus
supplement (and other relevant documents), and assuming full compliance with
the terms of the trust agreement (and other relevant documents), Morgan
Stanley Trust will be characterized for United States federal income tax
purposes as a grantor trust and will not be characterized as an association
taxable as a corporation. Accordingly, for United States federal income tax
purposes, each holder of the capital securities generally will be considered
the owner of an undivided portion of the junior subordinated debentures owned
by Morgan Stanley Trust, and each U.S. Holder will be required to include all
income or gain recognized for United States federal income tax purposes with
respect to its allocable share of the junior subordinated debentures on its
own income tax return.

         Characterization of the Junior Subordinated Debentures. Morgan
Stanley and Morgan Stanley Trust will agree to treat the junior subordinated
debentures as indebtedness for all United States federal income tax purposes.
Under current law and based on the representations, facts and assumptions set
forth in this prospectus supplement (and other relevant documents), and
assuming full compliance with the terms of the junior subordinated debt
indenture (and other relevant documents), the junior subordinated debentures
will be characterized for United States federal income tax purposes as
indebtedness of Morgan Stanley.

         Interest Income and Original Issue Discount. Under the terms of the
junior subordinated debentures, Morgan Stanley has the ability to defer
payments of interest from time to time by extending the interest payment
period for a period not exceeding 20 consecutive quarterly periods, but not
beyond the maturity of the junior subordinated debentures. Treasury
regulations under Sections 1273 and 1275 of the Code provide that debt
instruments like the junior subordinated debentures will not be considered
issued with original issue discount ("OID") by reason of Morgan Stanley's
ability to defer payments of interest if the likelihood of such deferral is
"remote."

         Morgan Stanley has concluded, and this discussion assumes, that, as
of the date of this prospectus supplement, the likelihood of deferring
payments of interest under the terms of the junior subordinated debentures is
"remote" within the meaning of the Treasury regulations referred to above, in
part because exercising that option generally would prevent Morgan Stanley
from declaring dividends on its capital stock and generally would prevent
Morgan Stanley from making any payments on debt securities that rank equal or
junior to the junior subordinated debentures. Therefore, the junior
subordinated debentures should not be treated as initially having been issued
with OID by reason of Morgan Stanley's deferral option. Rather, stated
interest on the junior subordinated debentures should generally be taxable to
a U.S. Holder as ordinary income when paid or accrued in accordance with that
holder's regular method of accounting for United States federal income tax
purposes. It should be noted, however, that these Treasury regulations have
not yet been interpreted in any rulings or any other



                                     S-38


published authorities of the IRS. Accordingly, it is possible that the IRS
could take a position contrary to the interpretation described above.

         In the event Morgan Stanley exercises its option to defer payments of
interest, the junior subordinated debentures would be treated as redeemed and
reissued for OID purposes and the sum of the remaining interest payments (and
any de minimis OID (generally an amount of OID which is less than .0025
multiplied by the product of the stated redemption price at maturity and the
number of complete years to maturity)) on the junior subordinated debentures
would thereafter be treated as OID, which would accrue, and be includible in a
U.S. Holder's taxable income, on an economic accrual basis (regardless of the
U.S. Holder's regular method of accounting for United States federal income
tax purposes) over the remaining term of the junior subordinated debentures
(including any period of interest deferral), without regard to the timing of
payments under the junior subordinated debentures. Subsequent distributions of
interest on the junior subordinated debentures generally would not, by
themselves, be separately taxable. The amount of OID that would accrue in any
period would generally equal the amount of interest that accrued on the junior
subordinated debentures in that period at the stated interest rate.
Consequently, during any period of interest deferral, U.S. Holders will
include OID in gross income in advance of the receipt of cash, and a U.S.
Holder that disposes of a capital security prior to the record date for
payment of distributions on the junior subordinated debentures following that
period will be subject to income tax on OID accrued through the date of
disposition (and not previously included in income), but will not receive cash
from Morgan Stanley Trust with respect to the OID.

         If the possibility of Morgan Stanley's exercising its option to defer
payments of interest is not treated as remote, the junior subordinated
debentures would be treated as initially having been issued with OID in an
amount equal to the aggregate stated interest (plus any de minimis OID). That
OID would generally be includible in a U.S. Holder's taxable income, over the
term of the junior subordinated debentures, on an economic accrual basis as
described above.

         Characterization of Income. Because the income underlying the capital
securities will not be characterized as dividends for income tax purposes, (i)
corporate holders of the capital securities will not be entitled to a
dividends-received deduction for any income received or accrued on the capital
securities and (ii) noncorporate individual holders will not be entitled to
any preferential tax rate for any income received on the capital securities.

         Market Discount and Bond Premium. Holders of the capital securities
other than Initial Holders may be considered to have acquired the capital
securities with market discount or bond premium. Prospective investors in the
capital securities should consult their own tax advisors regarding the
application of the market discount and bond premium rules to the purchase,
holding and disposition of the capital securities.

         Receipt of Junior Subordinated Debentures upon Liquidation of Morgan
Stanley Trust. Under certain circumstances described herein, Morgan Stanley
Trust may distribute the junior subordinated debentures to holders in exchange
for their capital securities and in liquidation of Morgan Stanley Trust. See
"Description of Capital Securities--Liquidation Distribution upon Dissolution"
in this prospectus supplement. Except as discussed below, a distribution of
the junior subordinated debentures would not be a taxable event for United
States federal income tax purposes, and each U.S. Holder would have an
aggregate adjusted basis for United States federal income tax purposes in the
junior subordinated debentures received equal to the U.S. Holder's aggregate
adjusted basis in the capital securities exchanged. For United States federal
income tax purposes, a U.S. Holder's holding period in the junior subordinated
debentures received in a liquidation of Morgan Stanley Trust would include the
period during which the capital securities were held by the holder. If,
however, the relevant event is a tax event that results in Morgan Stanley
Trust being treated as an association taxable as a corporation, the
distribution would likely constitute a taxable event to U.S. Holders of the
capital securities for United States federal income tax purposes.



                                     S-39


         Redemption for Cash. Under certain circumstances described in this
prospectus supplement, the junior subordinated debentures may be redeemed for
cash with the proceeds distributed to holders in redemption of their capital
securities. See "Description of Capital Securities" in this prospectus
supplement. A redemption of the capital securities would be taxable for United
States federal income tax purposes, and a U.S. Holder would recognize gain or
loss as if it had sold the capital securities for cash. See "--Sales of
Capital Securities" below.

         Sales of Capital Securities. A U.S. Holder that sells capital
securities will recognize gain or loss equal to the difference between its
adjusted basis in the capital securities and the amount realized on the sale
of the capital securities. A U.S. Holder's adjusted basis in the capital
securities generally will be its initial purchase price, increased by any OID
previously included (or currently includible) in the holder's gross income to
the date of disposition, and decreased by payments received on the capital
securities (other than any interest received with respect to the periods prior
to the effective date of Morgan Stanley's first exercise of its option to
defer payments of interest). Any gain or loss on the sale of the capital
securities generally will be capital gain or loss, and generally will be
long-term capital gain or loss if the capital securities have been held for
more than one year prior to the date of disposition.

         A U.S. Holder who disposes of its capital securities before the
record date for a payment of distributions will be required to include accrued
but unpaid interest (or OID) on the junior subordinated debentures through the
date of disposition in its taxable income for United States federal income tax
purposes (notwithstanding that the holder may receive a separate payment from
the purchaser with respect to accrued interest), and to deduct that amount
from the sales proceeds received (including the separate payment, if any, with
respect to accrued interest) for the capital securities (or as to OID only, to
add such amount to the holder's adjusted tax basis in its capital securities).
To the extent the selling price is less than the holder's adjusted tax basis
(which will include accrued but unpaid OID, if any), a holder will recognize a
capital loss. Subject to certain limited exceptions, capital losses cannot be
applied to offset ordinary income for United States federal income tax
purposes.

Non-U.S. Holders

         The following discussion applies to Non-U.S. Holders.

         Payments to a holder of a capital security that is a Non-U.S. Holder
will generally not be subject to withholding of income tax, provided that (a)
the beneficial owner of the capital security does not (directly or indirectly,
actually or constructively) own 10% or more of the total combined voting power
of all classes of stock of Morgan Stanley entitled to vote, (b) the beneficial
owner of the capital security is not a controlled foreign corporation that is
related to Morgan Stanley through stock ownership, (c) the beneficial owner of
the capital security is not a bank receiving interest described in Section
881(c)(3)(A) of the Code, (d) the beneficial owner's income and gain in
respect of a capital security is not effectively connected with the conduct of
a United States trade or business, and (e) Morgan Stanley Trust or its agent
has received from the beneficial owner of the capital security a properly
executed IRS Form W-8BEN or substantially similar form in the year in which
the payment occurs, or in a preceding calendar year to the extent provided for
in the instructions to the IRS Form W-8BEN.

         Changes in legislation affecting the income tax consequences of the
junior subordinated debentures are possible, and could adversely affect the
ability of Morgan Stanley to deduct the interest payable on the junior
subordinated debentures. Moreover, any changes in legislation could adversely
affect Non-U.S. Holders by characterizing income derived from the junior
subordinated debentures as dividends, generally subject to a 30% withholding
tax (or a lower rate under an applicable treaty) when paid to a Non-U.S.
Holder, rather than as interest, which, as discussed above, is generally
exempt from income tax in the hands of a Non-U.S. Holder.

         A Non-U.S. Holder of a capital security will generally not be subject
to withholding of income tax on any gain realized upon the sale or other
disposition of a capital security unless, in the case of certain Non-U.S.



                                     S-40


Holders who are nonresident alien individuals, the non-U.S. Holder is present
in the United States for 183 or more days in the taxable year of disposition
and certain other requirements are met.

         Notwithstanding the foregoing, in general, a Non-U.S. Holder will be
subject to regular United States federal income tax in the same manner as a
U.S. Holder with respect to its investment in the capital securities, if that
investment is effectively connected with the Non-U.S. Holder's conduct of a
trade or business in the United States. In addition, a corporate Non-U.S.
Holder that receives income that is or is deemed effectively connected with a
trade or business in the United States may also be subject to the branch
profits tax under Section 884 of the Code at the rate of 30% (or lower treaty
rate). This tax is payable in addition to regular United States federal
corporate income tax. To obtain an exemption from withholding on capital
securities effectively connected with the conduct of a trade or business in
the United States, the Non-U.S. Holder must generally supply to the
withholding agent an IRS Form W-8ECI.

Information Reporting

         In general, information reporting requirements will apply to payments
made on, and proceeds from the sale of, the capital securities held by a
noncorporate U.S. Holder within the United States. In addition, payments made
on, and payments of the proceeds from the sale of, the capital securities to
or through the United States office of a broker are subject to information
reporting unless the holder thereof certifies as to its Non-U.S. Holder status
or otherwise establishes an exemption from information reporting and backup
withholding. See "--Backup Withholding" below. Taxable income on the capital
securities for a calendar year should be reported to U.S. Holders on the
appropriate form by the following January 31st.

Backup Withholding

         Payments made on, and proceeds from the sale of, the capital
securities may be subject to a "backup" withholding tax at the applicable
statutory rate of United States federal income tax unless the holder complies
with certain identification or exemption requirements. Any amounts so withheld
will be allowed as a credit against the holder's income tax liability, or
refunded, provided the required information is provided to the IRS.

         THE PRECEDING DISCUSSION IS ONLY A SUMMARY AND DOES NOT ADDRESS THE
CONSEQUENCES TO A PARTICULAR HOLDER OF THE PURCHASE, OWNERSHIP AND DISPOSITION
OF THE CAPITAL SECURITIES. POTENTIAL HOLDERS OF THE CAPITAL SECURITIES ARE
URGED TO CONTACT THEIR OWN TAX ADVISORS TO DETERMINE THEIR PARTICULAR TAX
CONSEQUENCES.



                                     S-41



                         CERTAIN ERISA CONSIDERATIONS

         Each fiduciary of a pension, profit-sharing or other employee benefit
plan to which Title I of the Employee Retirement Income Security Act of 1974
("ERISA") applies (a "Plan"), should consider the fiduciary standards of ERISA
in the context of the Plan's particular circumstances before authorizing an
investment in the capital securities. Accordingly, among other factors, the
fiduciary should consider whether the investment would satisfy the prudence
and diversification requirements of ERISA and would be consistent with the
documents and instruments governing the Plan.

         Section 406 of ERISA and Section 4975 of the Internal Revenue Code
prohibit Plans, as well as individual retirement accounts and Keogh plans to
which Section 4975 of the Internal Revenue Code applies (also "Plans"), from
engaging in specified transactions involving "plan assets" with persons who
are "parties in interest" under ERISA or "disqualified persons" under the
Internal Revenue Code ("Parties in Interest") with respect to such Plan. A
violation of those "prohibited transaction" rules may result in an excise tax
or other liabilities under ERISA and/or Section 4975 of the Internal Revenue
Code for such persons, unless exemptive relief is available under an
applicable statutory or administrative exemption.

         Employee benefit plans that are governmental plans, as defined in
Section 3(32) of ERISA, certain church plans, as defined in Section 3(33) of
ERISA, and non-U.S. plans, as described in Section 4(b)(4) of ERISA, are not
subject to the requirements of ERISA or Section 4975 of the Internal Revenue
Code, but may be subject to similar rules under other applicable laws or
documents ("Similar Laws").

         Under a regulation (the "Plan Assets Regulation") issued by the U.S.
Department of Labor, the assets of Morgan Stanley Trust would be deemed to be
"plan assets" of a Plan for purposes of ERISA and Section 4975 of the Internal
Revenue Code if a Plan makes an "equity" investment in Morgan Stanley Trust
and no exception were applicable under the Plan Assets Regulation. An "equity
interest" is defined under the Plan Assets Regulation as any interest in an
entity other than an instrument that is treated as indebtedness under
applicable local law and which has no substantial equity features and
specifically includes a beneficial interest in a trust.

         If the assets of Morgan Stanley Trust were deemed to be "plan
assets," the persons providing services to the assets of Morgan Stanley Trust
may become Parties in Interest with respect to an investing Plan and may be
governed by the fiduciary responsibility provisions of Title I of ERISA and
the prohibited transaction provisions of ERISA and Section 4975 of the
Internal Revenue Code with respect to transactions involving those assets.

         In this regard, if the person or persons with discretionary
responsibilities over the junior subordinated debentures or the guarantee were
affiliated with Morgan Stanley, any such discretionary actions taken regarding
those assets could be deemed to constitute a prohibited transaction under
ERISA or the Internal Revenue Code (e.g., the use of such fiduciary authority
or responsibility in circumstances under which those persons have interests
that may conflict with the interests of the investing Plans and affect the
exercise of their best judgment as fiduciaries).

         Under an exception contained in the Plan Assets Regulation, the
assets of Morgan Stanley Trust would not be deemed to be "plan assets" of
investing Plans if the capital securities are "publicly-offered securities" -
that is, they are:

         o    widely held, i.e., owned by more than 100 investors independent
              of Morgan Stanley Trust and of each other;

         o    freely transferable; and



                                     S-42


         o    sold to a Plan as part of an offering pursuant to an effective
              registration statement under the Securities Act of 1933 (the
              "Securities Act"), and then timely registered under Section 12(b)
              or 12(g) of the Exchange Act.

         Morgan Stanley expects that the capital securities will meet the
criteria of "publicly-offered securities" above, although no assurance can be
given in this regard. The underwriters expect that the capital securities will
be held by at least 100 independent investors at the conclusion of the
offering and that the capital securities will be freely transferable. The
capital securities will be sold as part of an offering under an effective
registration statement under the Securities Act, and then will be timely
registered under the Exchange Act.

         All of the common securities will be purchased and held by Morgan
Stanley. Even if the assets of Morgan Stanley Trust are not deemed to be "plan
assets" of Plans investing in Morgan Stanley Trust, specified transactions
involving Morgan Stanley Trust could be deemed to constitute direct or
indirect prohibited transactions under Section 406 of ERISA and Section 4975
of the Internal Revenue Code regarding an investing Plan.

         For example, if Morgan Stanley were a Party in Interest with respect
to an investing Plan, either directly or by reason of the activities of one or
more of its affiliates, extensions of credit between Morgan Stanley and Morgan
Stanley Trust, as represented by the junior subordinated debentures and the
guarantee, would likely be prohibited by Section 406(a)(1)(B) of ERISA and
Section 4975(c)(1)(B) of the Internal Revenue Code, unless exemptive relief
were available under an applicable administrative exemption.

         The U.S. Department of Labor has issued five prohibited transaction
class exemptions ("PTCEs") that may provide exemptive relief for direct or
indirect prohibited transactions resulting from the purchase or holding of the
capital securities. Those class exemptions are:

         o    PTCE 96-23, for specified transactions determined by in-house
              asset managers;

         o    PTCE 95-60, for specified transactions involving insurance
              company general accounts;

         o    PTCE 91-38, for specified transactions involving bank collective
              investment funds;

         o    PTCE 90-1, for specified transactions involving insurance
              company separate accounts; and

         o    PTCE 84-14, for specified transactions determined by independent
              qualified professional asset managers.

         The capital securities may not be purchased or held by any Plan, any
entity whose underlying assets include "plan assets" by reason of any Plan's
investment in the entity (a "Plan Asset Entity") or any person investing "plan
assets" of any Plan, unless the purchaser or holder is eligible for the
exemptive relief available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or
there is some other basis on which the purchase and holding of the securities
by the Plan or Plan Asset Entity is not prohibited.

         Any purchaser or holder of the capital securities or any interest in
the capital securities will be deemed to have represented by its purchase and
holding that either:

         o   it is not a Plan or a Plan Asset Entity and is not purchasing
             such securities on behalf of or with "plan  assets" of any
             Plan; or

         o   it is not a governmental, non-U.S. or church plan which is
             subject to Similar Laws; or



                                     S-43


         o   it is eligible for the exemptive relief available under PTCE
             96-23, 95-60, 91-38, 90-1 or 84-14 or Similar Laws with respect
             to such purchase or holding; or

         o   there is no basis on which the purchase and holding could
             constitute a prohibited transaction under Section 406 of ERISA,
             Section 4975 of the Internal Revenue Code or any Similar Laws.

         Due to the complexity of these rules and the penalties that may be
imposed upon persons involved in non-exempt prohibited transactions, it is
particularly important that fiduciaries or other persons considering
purchasing the capital securities on behalf of or with "plan assets" of any
Plan or a governmental, non-U.S. or church plan consult with their counsel
regarding the potential consequences if the assets of Morgan Stanley Trust
were deemed to be "plan assets" and the availability of exemptive relief under
PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or any other exemptive relief.

         Purchasers of the capital securities have the exclusive
responsibility for ensuring that their purchase and holding of the capital
securities does not violate the prohibited transaction rules of ERISA or the
Code. The sale of any capital securities to a Plan, Plan Asset Entity or any
other benefit plan investor ("Benefit Plan Investor") is in no respect a
representation by Morgan Stanley or any of its affiliates or representatives
that such an investment meets all relevant legal requirements with respect to
investments by such Benefit Plan Investors generally or any particular Benefit
Plan Investor, or that such an investment is appropriate for such Benefit Plan
Investors generally or any particular Benefit Plan Investor.

                                     S-45


         The underwriters are offering the capital securities subject to their
acceptance of the securities from Morgan Stanley Trust and subject to prior
sale. The underwriting agreement provides that the obligations of the several
underwriters to pay for and accept delivery of the capital securities are
conditioned upon the delivery of legal opinions by their counsel. The
underwriters are obligated to purchase all the capital securities, other than
those covered by the underwriters' over-allotment option, if any capital
securities are purchased.

         The underwriters initially propose to offer the capital securities
directly to the public at the public offering price set forth on the cover
page of this prospectus supplement. The underwriters may also offer the
capital securities to securities dealers at a price that represents a
concession not in excess of $.50 per capital security. Any underwriter may
allow, and dealers may reallow, a concession not in excess of $.45 per capital
security to certain other dealers. After the initial offering of the capital
securities, the offering price and other selling terms may from time to time
be changed by the underwriters.

         Because the proceeds from the sale of the capital securities will be
used to purchase the junior subordinated debentures issued by Morgan Stanley,
the underwriting agreement provides that Morgan Stanley will pay to the
underwriters as compensation for their services $.7875 per capital security or
$23,625,000 in the aggregate, or $27,168,750 in the aggregate if the
underwriters purchase all the additional securities to which they are entitled
under their over-allotment option. Morgan Stanley's offering expenses, not
including underwriting discounts and commissions, are estimated to be
approximately $215,000.

         Morgan Stanley Trust has granted to the underwriters an option,
exercisable for 30 days from the date of this prospectus supplement, to
purchase up to an additional 4,500,000 capital securities at the public
offering price on the cover page of this prospectus supplement. The
underwriters may exercise this option solely to cover over-allotments, if any,
made in connection with this offering. Morgan Stanley will pay to the
underwriters compensation in the amount per capital security stated above for
any additional capital securities. If the option is exercised, each
underwriter will be obligated, subject to certain conditions, to purchase
approximately the same percentage of additional capital securities as the
number set forth next to the underwriter's name in the preceding table bears
to the total number of capital securities offered by the underwriters.

         Morgan Stanley and Morgan Stanley Trust have agreed that, without the
prior written consent of Morgan Stanley & Co. Incorporated, on behalf of the
underwriters, they will not, during the period beginning on the date of the
underwriting agreement and continuing to and including the closing under the
underwriting agreement:

         o    offer, pledge, sell, contract to sell, sell any option or
              contract to purchase, purchase any option or contract to sell,
              grant any option, right or warrant to purchase, lend or
              otherwise transfer or dispose of, directly or indirectly, any
              securities of Morgan Stanley or Morgan Stanley Trust that are
              substantially similar to the capital securities or securities
              convertible into or exercisable or exchangeable for such
              securities; or

         o    enter into any swap or other arrangement that transfers to
              another, in whole or in part, any of the economic consequences of
              ownership of such securities,

whether any transactions described above are to be settled by securities, in
cash or otherwise, except in the offering.

         Prior to this offering, there has been no public market for the
capital securities. Morgan Stanley Trust will apply to list the capital
securities on the New York Stock Exchange. In order to meet one of the
requirements for listing the capital securities on the New York Stock
Exchange, the underwriters intend to sell capital securities to a minimum of
400 beneficial holders in lots of 100 capital securities or more. If the
listing is approved, trading of the capital securities on the New York Stock
Exchange is expected to commence within 30 days after



                                     S-46


they are first issued. The underwriters have advised Morgan Stanley Trust that
they presently intend to make a market in the capital securities prior to the
commencement of trading on the New York Stock Exchange. The underwriters are
not obligated to make a market in the capital securities, however, and may
discontinue market making activities at any time without notice. No assurance
can be given as to the liquidity of any trading market for the capital
securities.

         Morgan Stanley and Morgan Stanley Trust have agreed to indemnify the
underwriters and certain other persons against certain liabilities, including
liabilities under the Securities Act, and to contribute to payments the
underwriters may be required to make under the Securities Act.

         No action has been or will be taken by Morgan Stanley or any
underwriter that would permit a public offering of the capital securities or
possession or distribution of this prospectus supplement or the accompanying
prospectus or any other offering material relating to the capital securities
in any jurisdiction, other than the United States, where action for that
purpose is required. No offers, sales or deliveries of the capital securities,
or distribution of this prospectus supplement or the accompanying prospectus
or any other offering material relating to the capital securities, may be made
in or from any jurisdiction except in circumstances which will result in
compliance with any applicable laws and regulations and will not impose any
obligations on Morgan Stanley or any underwriter.

         Each underwriter has represented and agreed that it will comply with
all applicable laws and regulations in force in any jurisdiction in which it
purchases, offers, sells or delivers the capital securities or possesses or
distributes this prospectus supplement and the accompanying prospectus and
will obtain any consent, approval or permission required by it for the
purchase, offer or sale by it of the capital securities under the laws and
regulations in force in any jurisdiction to which it is subject or in which it
makes purchases, offers or sales and Morgan Stanley shall not have
responsibility therefor.

         The capital securities are not being offered or sold outside of the
United States.

         In order to facilitate the offering of the capital securities, the
underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of the capital securities. Specifically, the underwriters may
over-allot in connection with the offering, creating a short position in the
capital securities for their own account. A short sale is covered if the short
position is no greater than the number of capital securities available for
purchase by the underwriters under the over-allotment option. The underwriters
can close out a covered short sale by exercising the over-allotment option or
purchasing capital securities in the open market. In determining the source of
capital securities to close out a covered short sale, the underwriters will
consider, among other things, the open market price of the capital securities
compared to the price available under the over-allotment option. The
underwriters may also sell capital securities in excess of the over-allotment
option, creating a naked short position. The underwriters must close out any
naked short position by purchasing capital securities in the open market. A
naked short position is more likely to be created if the underwriters are
concerned that there may be downward pressure on the price of the capital
securities in the open market after pricing that could adversely affect
investors who purchase capital securities in the offering. As an additional
means of facilitating the offering of capital securities, the underwriters may
bid for and purchase these capital securities in the open market to stabilize
the price of these capital securities. Finally, the underwriting syndicate may
reclaim selling concessions allowed to an underwriter or a dealer for
distributing the capital securities in the offering, if the syndicate
repurchases previously distributed capital securities in transactions to cover
syndicate short positions, in stabilization transactions or otherwise. Any of
these activities may stabilize or maintain the market price of the capital
securities above independent market levels or prevent or retard a decline in
the market price of the capital securities. The underwriters are not required
to engage in these activities, and may end any of these activities at any
time.


                                     S-47


         This prospectus supplement and the accompanying prospectus may be
used by Morgan Stanley & Co. Incorporated and Morgan Stanley affiliates in
connection with offers and sales of the capital securities in market-making
transactions at negotiated prices related to prevailing market prices at the
time of sale or otherwise. Morgan Stanley & Co. Incorporated and Morgan
Stanley affiliates may act as principal or agent in such transactions.

         Morgan Stanley & Co. Incorporated is a wholly-owned subsidiary of
Morgan Stanley. The Administrators appointed by Morgan Stanley Trust are
employees or officers of Morgan Stanley & Co. Incorporated or its affiliates.
The participation of Morgan Stanley & Co. Incorporated in the offering of the
capital securities will be conducted in compliance with Rule 2720 of the
Conduct Rules of the National Association of Securities Dealers, Inc.

         The underwriters and any dealers utilized in the sale of capital
securities do not intend to confirm sales to accounts over which they exercise
discretionary authority without the prior specific written approval of such
customers.

         It is expected that delivery of the capital securities will be made
against payment therefor on or about the date specified in the last paragraph
of the cover page of this prospectus supplement, which will be the fifth
business day following the date of the pricing of the capital securities.
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 capital securities on the date of pricing or the next succeeding
business day will be required, by virtue of the fact that the capital
securities initially will settle in T+5, to specify alternative settlement
arrangements to prevent a failed settlement.

                            VALIDITY OF SECURITIES

         The validity of the capital securities will be passed on for Morgan
Stanley Trust by Richards, Layton & Finger, P.A. The validity of the junior
subordinated debentures and the guarantees will be passed upon for Morgan
Stanley by Sidley Austin LLP. Certain legal matters relating to the securities
will be passed upon for the underwriters by Davis Polk & Wardwell. Davis Polk
& Wardwell has in the past represented Morgan Stanley and continues to
represent Morgan Stanley on a regular basis and in a variety of matters,
including in connection with its private equity and leveraged capital
activities.

financial reporting, which are incorporated in this prospectus supplement and
the accompanying prospectus by reference to Exhibit No. 99.1 of Morgan
Stanley's Current Report on Form 8-K filed October 12, 2005, Schedule I of
Morgan Stanley's Annual Report on Form 10-K for the fiscal year ended November
30, 2004, filed on February 11, 2005 ("2004 Form 10-K") and Item 9A of the
2004 Form 10-K, respectively, have been audited by Deloitte & Touche LLP, an
independent registered public accounting firm, as stated in their reports,
which are incorporated herein by reference (which reports (1) express an
unqualified opinion on the financial statements and financial statement
schedule and include an explanatory paragraph referring to the adoption of
Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for
Stock-Based Compensation, as amended by SFAS No. 148, Accounting for

control over financial reporting) and have been so included in reliance upon
the reports of such firm given upon their authority as experts in accounting
and auditing.

         With respect to the unaudited interim financial information for the
periods ended February 28, 2005 and February 29, 2004, May 31, 2005 and May
31, 2004 and August 31, 2005 and August 31, 2004, which is incorporated herein
by reference, Deloitte & Touche LLP, an independent registered public
accounting firm, have applied limited procedures in accordance with the
standards of the Public Company Accounting Oversight Board (United States) for
a review of such information. However, as stated in their reports included in
Morgan Stanley's Quarterly Report on Form 10-Q for the quarter ended August
31, 2005 and in Exhibit Nos. 99.2 and 99.3 of Morgan Stanley's Current Report
on Form 8-K filed October 12, 2005, and incorporated by reference herein, they
did not audit and they do not express an opinion on the interim financial
information. Accordingly, the degree of reliance on their reports on such
information should be restricted in light of the limited nature of the review
procedures applied. Deloitte & Touche LLP are not subject to the liability
provisions of Section 11 of the Securities Act for their reports on the
unaudited interim financial information because those reports are not reports
or a part of the registration statement prepared or certified by an accountant
within the meaning of Sections 7 and 11 of the Securities Act.

    There are no separate financial statements of the Morgan Stanley Capital
Trusts in this prospectus. We do not believe these financial statements would
be material to holders of the capital securities because:

o     the Morgan Stanley Capital Trusts are special purpose entities that will
      not have any independent operations other than issuing capital
      securities and common securities, which are together referred to as
      "trust securities," holding junior subordinated debentures of Morgan
      Stanley as trust assets and other necessary or incidental activities as
      described in this prospectus; and

o     Morgan Stanley guarantees the payments on the capital securities of the
      Morgan Stanley Capital Trusts.

      We do not expect any of the Morgan Stanley Capital Trusts will be
subject to the reporting requirements of the Securities Exchange Act of 1934.

consolidated subsidiaries.

                      THE MORGAN STANLEY CAPITAL TRUSTS

    We created the Morgan Stanley Capital Trusts, each of which is a Delaware
statutory trust, pursuant to trust agreements and the filing of certificates
of trust with the Delaware Secretary of State. We will execute amended and
restated trust agreements for the Morgan Stanley Capital Trusts, referred to
in this prospectus as the "trust agreements," which will state the terms and
conditions for the Morgan Stanley Capital Trusts to issue and sell their trust
securities. We have filed a form of trust agreement as an exhibit to the
registration statement of which this prospectus forms a part. We, as holder of
the common securities, intend to select two of our employees, officers or
affiliates to serve as administrators of the Morgan Stanley Capital Trusts.


                                      5



Each Morgan Stanley Capital Trust exists solely to

        o   issue and sell its trust securities;

        o   use the proceeds from the sale of its trust securities to
            purchase Morgan Stanley's junior subordinated debentures; and

        o   engage in other activities that are necessary, convenient or
            incidental to the above purposes (such as registering the transfer
            of trust securities).

      Accordingly, our junior subordinated debentures will be the sole assets
of each Morgan Stanley Capital Trust, and payments under the junior
subordinated debentures owned by each Morgan Stanley Capital Trust will be its
sole source of revenues.

      We will hold directly or indirectly all of the common securities of each
of the Morgan Stanley Capital Trusts. Unless otherwise specified in the
applicable prospectus supplement, the common securities will represent an
aggregate liquidation amount equal to at least 3% of each Morgan Stanley
Capital Trust's total capitalization. The capital securities will represent
the remaining percentage of each Morgan Stanley Capital Trust's total
capitalization. The common securities will have terms substantially identical
to, and will rank equal in priority of payment with, the capital securities.
However, if Morgan Stanley defaults in payments due under the junior
subordinated debentures owned by a Morgan Stanley Capital Trust, then
distributions, redemption payments and liquidation payments must be paid to
the holders of the capital securities of that trust before any payments are
paid to the holders of the common securities of that trust. Unless otherwise
specified in the applicable prospectus supplement, each Morgan Stanley Capital
Trust will have a term of approximately 50 years from the initial issue date
of its capital securities, but may dissolve earlier as provided in the
applicable trust agreement and described in the applicable prospectus
supplement. Unless otherwise specified in the applicable prospectus
supplement, the name and address of the Delaware trustee for each Morgan
Stanley Capital Trust will be The Bank of New York (Delaware), White Clay
Center, Route 273, Newark, Delaware 19711, and the name and address of the
property trustee, the guarantee trustee and the indenture trustee for each
Morgan Stanley Capital Trust will be The Bank of New York, 101 Barclay Street,
Floor 8 West, New York, New York 10286.

      The capital securities will be guaranteed by us as described in this
prospectus and the applicable prospectus supplement.

      Only we, as direct or indirect owner of the common securities, can
remove or replace the administrators. In addition, we can increase or decrease
the number of administrators. Also, we, as direct or indirect holder of the
common securities, will generally have the sole right to remove or replace the
property trustee and Delaware trustee. However, if a default with respect to
the junior subordinated debentures occurs, then, so long as that default is
continuing, the holders of a majority in liquidation amount of the outstanding
capital securities of that trust may remove and replace the property trustee
and Delaware trustee for that trust at any time.

      We will pay all fees and expenses related to the organization of the
Morgan Stanley Capital Trusts and the offering of the capital securities. We
will also pay all ongoing costs and expenses of the Morgan Stanley Capital
Trusts, except each trust's obligations under the trust securities.

                               USE OF PROCEEDS

      The Morgan Stanley Capital Trusts will use all proceeds from the sale of
trust securities to purchase junior subordinated debentures from us. Unless
otherwise set forth in the applicable prospectus supplement, we intend to use
the net proceeds from the sale of our junior subordinated debentures for
general corporate purposes, which may include, among other things:


      o     additions to working capital;

      o     the redemption of outstanding preferred stock;

      o     the repurchase of outstanding common stock; and


                                      6




      o     the repayment of indebtedness.

      We anticipate that we will raise additional funds from time to time
through equity or debt financing, including borrowings under revolving credit
agreements, to finance our businesses worldwide.

             CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES AND
           EARNINGS TO FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

    The following table sets forth Morgan Stanley's consolidated ratios of
earnings to fixed charges and earnings to fixed charges and preferred stock
dividends for the periods indicated.

      For purposes of calculating the ratio of earnings to fixed charges and
the ratio of earnings to fixed charges and preferred stock dividends, earnings
are the sum of:

        o   income before losses from unconsolidated investees, income taxes,
            (loss)/gain on discontinued operations, cumulative effect of
            accounting change and fixed charges;

    less:

        o   dividends on preferred securities subject to mandatory redemption.

    For purposes of calculating both ratios, fixed charges are the sum of:

        o   interest cost, including interest on deposits;

        o   dividends on preferred securities subject to mandatory redemption;
            and

        o   that portion of rent expense estimated to be representative of the
            interest factor.

      The preferred stock dividend amounts represent pre-tax earnings required
to cover dividends on preferred stock.

                      DESCRIPTION OF CAPITAL SECURITIES

      Each Morgan Stanley Capital Trust will issue only one series of capital
securities and one series of common securities. The trust agreement for each
Morgan Stanley Capital Trust will be qualified as an indenture under the Trust
Indenture Act of 1939. The capital securities will have terms and will be
subject to conditions as set forth in the trust agreement or made a part of
the trust agreement by the Trust Indenture Act. This summary of certain
provisions of the capital securities and each trust agreement does not purport
to be complete and is subject to, and qualified in its entirety by reference
to, all the provisions of each trust agreement, including the definitions of
certain terms, and those provisions made part of each trust agreement by the
Trust Indenture Act. A form of the trust agreement to be used in connection
with the issuance of the capital securities and a form of the capital
securities are filed as exhibits to the registration statement that includes
this prospectus. Wherever particular defined terms of a trust agreement are
referred to in this prospectus, those defined terms are incorporated in this
prospectus by reference. A copy of the form of the trust agreement is
available upon request from the property trustee of the relevant trust.

General

      The capital securities will represent preferred undivided beneficial
interests in the assets of the applicable Morgan Stanley Capital Trust. The
only assets of a Morgan Stanley Capital Trust, and its only source of
revenues,


                                      7




will be the junior subordinated debentures purchased by the Morgan
Stanley Capital Trust with the proceeds from the sale of its trust securities.
Accordingly, distribution and other payment dates for the trust securities
will correspond with the interest and other payment dates for the junior
subordinated debentures. If we do not make payments on the junior subordinated
debentures in accordance with their terms, the Morgan Stanley Capital Trust
will not have funds available to pay distributions or other amounts payable on
the trust securities issued by that Morgan Stanley Capital Trust in accordance
with their terms. The capital securities issued by a Morgan Stanley Capital
Trust will rank equally, and payments will be made proportionately, with the
common securities issued by that Morgan Stanley Capital Trust except as
described below under "-Subordination of Common Securities" and in the
applicable prospectus supplement. Payments on the capital securities will be
fully and unconditionally guaranteed by us to the extent described under
"Description of Guarantees" and in the applicable prospectus supplement.

      The Morgan Stanley Capital Trusts may offer up to $30,950,247,612.69
aggregate offering price of capital securities, subject to reduction on
account of the sale of other securities under the registration statement of
which this prospectus is a part.

      Each Morgan Stanley Capital Trust will describe the specific terms of
the capital securities it is offering in the applicable prospectus supplement,
including:

      o     the specific designation, liquidation amount, number to be issued
            by the Morgan Stanley Capital Trust and purchase price;

      o     the currency or units based on or relating to currencies in which
            distributions and other payments will or may be payable;

      o     the distribution rates (or the method by which the rates will be
            determined), if any;

      o     the dates on which any distributions will be payable;

      o     any provisions relating to deferral of distribution payments;

      o     the places where distributions and other amounts payable on the
            capital securities will be payable;

      o     any repayment, redemption, prepayment or sinking fund provisions;

      o     any conversion or exchange provisions;

      o     the voting rights, if any, of holders of the capital securities;

      o     the terms and conditions, if any, upon which the assets of the
            Morgan Stanley Capital Trust may be distributed to holders of the
            capital securities;

      o     any applicable United States federal income tax consequences; and

      o     any other specific terms of the capital securities.

      If indicated in the applicable prospectus supplement, the terms of the
trust agreement for, and capital securities offered by, a Morgan Stanley
Capital Trust may differ from the terms summarized in this prospectus.

Distributions

      Distributions on the capital securities will be cumulative, unless
otherwise indicated in the applicable prospectus supplement. Distributions
will accumulate from and including the date of original issuance and will be
payable on the dates specified in the applicable prospectus supplement. The
amount of distributions payable for any period less than a full distribution
period will be computed on the basis of a 360-day year of twelve 30-day months
and the actual days elapsed in a partial month in that period, unless
otherwise specified in the applicable prospectus supplement. Distributions
payable for each full distribution period will be computed by dividing the
annual rate by four, unless otherwise specified in the applicable prospectus
supplement.

                                      8





Subordination of Common Securities

      Payment of distributions on, and other amounts payable under, the
capital securities and the common securities issued by a Morgan Stanley
Capital Trust will be made proportionately based on the liquidation amount of
the capital securities and the common securities. However, unless otherwise
provided in the applicable prospectus supplement, if on any distribution date
or other payment date, a default with respect to the junior subordinated
debentures, which we refer to as a "debenture default," owned by the Morgan
Stanley Capital Trust has occurred and is continuing as a result of any
failure by us to pay any amounts in respect of the junior subordinated
debentures when due, no payment of any distribution on, or other amounts
payable under, the common securities will be made unless cash payment in full
of all accumulated amounts then due and payable with respect to all of the
Morgan Stanley Capital Trust's outstanding capital securities has been made or
provided for, and all funds immediately available to the property trustee will
first be applied to the cash payment in full of all distributions on, and all
other amounts with respect to, capital securities then due and payable.

      In the case of any event of default under the applicable trust agreement
occurring as a result of a debenture default, the holders of the applicable
Morgan Stanley Capital Trust's common securities will have no right to act
with respect to the event of default under the applicable trust agreement
until the effects with respect to the capital securities of all events of
default resulting from a debenture default have been cured, waived or
otherwise eliminated. Until all of the events of default resulting from a
debenture default have been cured, waived or otherwise eliminated, the
property trustee will act solely on behalf of the holders of the capital
securities and not on behalf of the holders of the common securities, and only
the holders of the capital securities will have the right to direct the
property trustee to act on their behalf.

Liquidation Distribution upon Dissolution

      The amount payable on capital securities in the event of any liquidation
of a Morgan Stanley Capital Trust will be the stated liquidation amount per
capital security or other amount as specified in the applicable prospectus
supplement plus accumulated and unpaid distributions, which, if specified in
the applicable prospectus supplement, may be in the form of a distribution of
the junior subordinated debentures owned by the Morgan Stanley Capital Trust.

      The holders of all the outstanding common securities of a Morgan Stanley
Capital Trust will have the right at any time to dissolve the Morgan Stanley
Capital Trust and, after satisfaction of liabilities to creditors of the
Morgan Stanley Capital Trust as provided by applicable law, cause the junior
subordinated debentures owned by the Morgan Stanley Capital Trust to be
distributed to the holders of the capital securities and common securities in
liquidation of the Morgan Stanley Capital Trust as described in the applicable
prospectus supplement. Other terms for the dissolution of a Morgan Stanley
Capital Trust and the distribution or liquidation of its assets to holders of
trust securities will be set forth in the applicable prospectus supplement.

Capital Securities Events of Default; Notice

      Any one of the following events constitutes an event of default under a
trust agreement, which we refer to as a "capital securities event of default,"
regardless of the reason for the capital securities event of default and
whether it is voluntary or involuntary or effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body:

      o     the occurrence of a default with respect to the junior
            subordinated debentures in which the proceeds from the sale of the
            trust securities have been invested;

      o     default by the applicable Morgan Stanley Capital Trust or the
            property trustee in the payment of any distribution on the capital
            securities when it becomes due and payable, and continuation of
            the default for a period of 30 days;

      o     default by the applicable Morgan Stanley Capital Trust or the
            property trustee in the payment of any redemption price of any
            trust security issued pursuant to its trust agreement when it
            becomes due and payable;


                                      9




      o     default in the performance, or breach, in any material respect, of
            any covenant or warranty of the applicable property trustee and
            Delaware trustee (other than a covenant or warranty described
            above dealing with default in the payment of any distribution or
            redemption price) and continuation of such default or breach for a
            period of 60 days after written notice has been given, by
            registered or certified mail, to the applicable property trustee
            and Delaware trustee and us by the holders of at least 25% in
            aggregate liquidation amount of the capital securities
            outstanding, which notice must specify the default or breach,
            demand it be remedied and state that it is a "Notice of Default"
            under the applicable trust agreement; or

      o     the occurrence of certain events of bankruptcy or insolvency with
            respect to the property trustee or all or substantially all of its
            property if a successor property trustee has not been appointed
            within 90 days of the event.

      Within ten business days after the occurrence of any capital securities
event of default actually known to the property trustee, the property trustee
will transmit notice of the event of default to the holders of the applicable
trust securities and the administrators, unless the capital securities event
of default has been cured or waived. In addition, the property trustee will
notify each holder of the capital securities of any notice of default received
by it with respect to the junior subordinated debentures. We, as depositor,
and the administrators are required to file annually with the property trustee
a certificate as to whether or not the applicable Morgan Stanley Capital Trust
is in compliance with all the conditions and covenants under its trust
agreement.

      If a debenture default has occurred and is continuing as a result of any
failure by us to pay any amounts in respect of the junior subordinated
debentures owned by a Morgan Stanley Capital Trust when due, the capital
securities issued by that Morgan Stanley Capital Trust will have a preference
over the common securities issued by the Morgan Stanley Capital Trust with
respect to payments of any amounts in respect of the capital securities as
described above under "--Subordination of Common Securities."

Removal of Morgan Stanley Capital Trustees; Appointment of Successors

      The holders of at least a majority in aggregate liquidation amount of
the outstanding capital securities may remove the property trustee or the
Delaware trustee for cause or, if a debenture default has occurred and is
continuing, with or without cause. If a property trustee or Delaware trustee
is removed by the holders of the outstanding capital securities, the successor
may be appointed by the holders of at least 25% in liquidation amount of the
outstanding capital securities. If a property trustee or Delaware trustee
resigns, the resigning property trustee or Delaware trustee will appoint its
successor. If a resigning property trustee or Delaware trustee fails to
appoint a successor, the holders of at least 25% in liquidation amount of the
outstanding capital securities may appoint a successor. If a successor has not
been appointed by the holders, any holder of capital securities or common
securities or the property trustee or the Delaware trustee may petition a
court of competent jurisdiction to appoint a successor. Any Delaware trustee
must meet the applicable requirements of Delaware law. Any property trustee
must be a national or state-chartered bank and at the time of appointment have
capital and surplus of at least $50,000,000. No resignation or removal of a
property trustee or Delaware trustee and no appointment of a successor trustee
shall be effective until the acceptance of appointment by the successor
trustee in accordance with the provisions of the applicable trust agreement.

Merger or Consolidation of Morgan Stanley Capital Trustees

      Any entity into which a property trustee or Delaware trustee is merged
or converted or with which it is consolidated, or any entity resulting from
any merger, conversion or consolidation to which the property trustee or the
Delaware trustee is a party, or any entity succeeding to all or substantially
all the corporate trust business of the property trustee or the Delaware
trustee, will be the successor of that property trustee or Delaware trustee
under each trust agreement, provided it is otherwise qualified and eligible.

Mergers, Consolidations, Amalgamations or Replacements of the Morgan Stanley
Capital Trusts

      A Morgan Stanley Capital Trust may not merge with or into, consolidate
or amalgamate with, be replaced by, or convey, transfer or lease its
properties and assets substantially as an entirety to, any entity, except as
described below or as otherwise set forth in the applicable trust agreement. A
Morgan Stanley Capital Trust may, at the


                                      10





request of the holders of its common securities and with the consent of the
holders of at least a majority in aggregate liquidation amount of its
outstanding capital securities, merge with or into, consolidate or amalgamate
with, be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, a trust organized as such under the laws of
any state of the United States, so long as

        o   the successor entity either:

            o     expressly assumes all the obligations of the Morgan Stanley
                  Capital Trust with respect to the capital securities of that
                  Morgan Stanley Capital Trust, or

            o     substitutes for the capital securities of that Morgan
                  Stanley Capital Trust other securities having substantially
                  the same terms as those capital securities so long as the
                  successor securities have the same priority as the capital
                  securities with respect to distributions and payments upon
                  liquidation, redemption and otherwise;

        o   the successor entity has a trustee possessing the same powers and
            duties as the property trustee appointed to hold the junior
            subordinated debentures;

        o   the merger, consolidation, amalgamation, replacement, conveyance,
            transfer or lease does not cause the capital securities of that
            Morgan Stanley Capital Trust (including any successor securities)
            to be downgraded by any nationally recognized statistical rating
            organization;

        o   the merger, consolidation, amalgamation, replacement, conveyance,
            transfer or lease does not adversely affect the rights,
            preferences and privileges of the holders of the capital
            securities (including any successor securities) in any material
            respect;

        o   the successor entity has a purpose substantially identical to that
            of the Morgan Stanley Capital Trust;

        o   prior to the merger, consolidation, amalgamation, replacement,
            conveyance, transfer or lease, the property trustee and Delaware
            trustee have received an opinion from independent counsel
            experienced in these matters to the effect that:

            o     the merger, consolidation, amalgamation, replacement,
                  conveyance, transfer or lease does not adversely affect the
                  rights, preferences and privileges of the holders of the
                  capital securities (including any successor securities) of
                  that Morgan Stanley Capital Trust in any material respect,
                  and

            o     following the merger, consolidation, amalgamation,
                  replacement, conveyance, transfer or lease, neither the
                  Morgan Stanley Capital Trust nor the successor entity will
                  be required to register as an "investment company" under the
                  Investment Company Act of 1940; and

        o   Morgan Stanley or any permitted transferee to whom Morgan Stanley
            has transferred the common securities owns, directly or
            indirectly, all of the common securities of the successor entity
            and guarantees the obligations of the successor entity with
            respect to the successor securities at least to the extent
            provided by the related guarantee with respect to the capital
            securities.

Notwithstanding the foregoing, a Morgan Stanley Capital Trust may not, except
with the consent of holders of 100% in aggregate liquidation amount of the
capital securities of that Morgan Stanley Capital Trust, merge with or into,
consolidate or amalgamate with, or be replaced by, or convey, transfer or
lease its properties and assets substantially as an entirety to, any other
entity or permit any other entity to merge with or into, consolidate or
amalgamate with, or replace it if such consolidation, amalgamation, merger,
replacement, conveyance, transfer or lease would cause the Morgan Stanley
Capital Trust or the successor entity to be taxable as a corporation for
United States federal income tax purposes.



                                      11



Voting Rights; Amendment of Trust Agreements

      Except as provided below and under "-Removal of Morgan Stanley Capital
Trustees; Appointment of Successors" and "Description of Guarantees-Amendments
and Assignment" and as otherwise required by law and the applicable trust
agreement, the holders of the capital securities will have no voting rights.

      Each trust agreement may be amended from time to time by the holders of
at least a majority in aggregate liquidation amount of the common securities
and the property trustee, without the consent of the holders of the capital
securities, to:

      o     cure any ambiguity, correct or supplement any provisions in the
            trust agreement that may be inconsistent with any other provision,
            or to make any other provisions with respect to matters or
            questions arising under the trust agreement, provided that the
            amendment will not adversely affect in any material respect the
            interests of any holder of trust securities; or

      o     modify, eliminate or add to any provisions of the trust agreement
            to the extent necessary to ensure that the Morgan Stanley Capital
            Trust will not be taxable as a corporation for United States
            federal income tax purposes at any time that any trust securities
            are outstanding or to ensure that the Morgan Stanley Capital Trust
            will not be required to register as an "investment company" under
            the Investment Company Act of 1940.

      Any amendment of the trust agreement without the consent of the holders
of the capital securities will become effective when notice of the amendment
is given to the holders of trust securities.

      Each trust agreement may be amended by the holders of at least a
majority in aggregate liquidation amount of the common securities and the
property trustee with:

      o     the consent of holders representing at least a majority in
            aggregate liquidation amount of the outstanding capital
            securities; and

      o     receipt by the Delaware trustee and the property trustee of an
            opinion of counsel to the effect that the amendment or the
            exercise of any power granted to the Delaware trustee and the
            property trustee in accordance with the amendment will not cause
            the Morgan Stanley Capital Trust to be taxable as a corporation
            for United States federal income tax purposes or affect the Morgan
            Stanley Capital Trust's exemption from status as an "investment
            company" under the Investment Company Act of 1940;

except that, without the consent of each holder of trust securities affected,
a trust agreement may not be amended to:

      o     change the amount or timing of any distribution on the trust
            securities or otherwise adversely affect the amount of any
            distribution required to be made in respect of the trust
            securities as of a specified date, or

      o     restrict the right of a holder of trust securities to institute
            suit for the enforcement of payment of any distribution on the
            trust securities on or after such date.

      So long as any junior subordinated debentures are held by a Morgan
Stanley Capital Trust, the property trustee will not:

      o     direct the time, method and place of conducting any proceeding for
            any remedy available to the indenture trustee, or execute any
            trust or power conferred on the property trustee with respect to
            the junior subordinated debentures,

      o     waive any past default that may be waived under the indenture,


                                      12




      o     exercise any right to rescind or annul a declaration of
            acceleration of the maturity of the principal amount of the junior
            subordinated debentures, or

      o     consent to any amendment, modification or termination of the
            indenture or junior subordinated debentures, where the consent is
            required,

without, in each case, obtaining the prior approval of the holders of at least
a majority in aggregate liquidation amount of the outstanding capital
securities, except that, if a consent under the indenture would require the
consent of each holder of the junior subordinated debentures affected, no
consent will be given by the property trustee without the prior consent of
each holder of the capital securities.

      In addition to obtaining the foregoing approvals of the holders of the
capital securities, before taking any of the foregoing actions, the property
trustee will obtain an opinion of counsel experienced in these matters to the
effect that the Morgan Stanley Capital Trust will not be taxable as a
corporation for United States federal income tax purposes on account of the
action. The property trustee may not revoke any action previously authorized
or approved by a vote of the holders of the capital securities issued by the
Morgan Stanley Capital Trust except by subsequent vote of the holders of the
capital securities.

      Any required approval of holders of capital securities may be given at a
meeting of holders of capital securities convened for that purpose or pursuant
to written consent. The property trustee will cause a notice of any meeting at
which holders of capital securities are entitled to vote, or of any matter
upon which action by written consent of the holders is to be taken, to be
given to each registered holder of capital securities in the manner set forth
in each trust agreement.

      No vote or consent of the holders of capital securities will be required
to redeem and cancel the capital securities in accordance with the applicable
trust agreement.

      Any capital securities that are owned by us, the Delaware trustee, the
property trustee, the administrators or any of our affiliates or affiliates of
any Delaware trustee or property trustee, will, for purposes of a vote or
consent under any of the circumstances described above, be treated as if they
were not outstanding.

Expenses and Taxes

      In the junior subordinated debentures owned by a Morgan Stanley Capital
Trust, we, as borrower, will agree to pay all debts and other obligations
(other than with respect to the capital securities issued by the Morgan
Stanley Capital Trust) and all costs and expenses of the Morgan Stanley
Capital Trust (including costs and expenses relating to the organization of
the Morgan Stanley Capital Trust, the fees and expenses of the Delaware
trustee and property trustee on behalf of the Morgan Stanley Capital Trust and
the costs and expenses relating to the operation of the Morgan Stanley Capital
Trust) and to pay any and all taxes and all costs and expenses with respect to
those taxes (other than United States withholding taxes) to which the Morgan
Stanley Capital Trust might become subject. The foregoing obligations under
the junior subordinated debentures owned by a Morgan Stanley Capital Trust are
for the benefit of, and shall be enforceable by, any person to whom any of
those debts, obligations, costs, expenses and taxes payable by the Morgan
Stanley Capital Trust are owed, whether or not that person has received notice
of the debts, obligations, costs, expenses or taxes. Any such person may
enforce these obligations directly against us, and we will irrevocably waive
any right or remedy to require that person to take any action against a Morgan
Stanley Capital Trust or any other person before proceeding against us. We
will also agree in the junior subordinated debentures owned by a Morgan
Stanley Capital Trust to execute additional agreements necessary or desirable
to give full effect to the foregoing.

Payment and Paying Agency

      The applicable prospectus supplement will specify the manner in which
payments in respect of the capital securities will be made. The paying agent
for capital securities will initially be the property trustee and any
co-paying agent chosen by the property trustee and acceptable to the
administrators. The paying agent will be permitted to resign as paying agent
upon 30 days' written notice to the property trustee and the administrators.
If the


                                      13




property trustee is no longer the paying agent, the property trustee
will appoint a successor (which must be a bank or trust company) reasonably
acceptable to the administrators to act as paying agent.

Registrar and Transfer Agent

      Unless otherwise specified in the applicable prospectus supplement, the
property trustee will act as registrar and transfer agent for the capital
securities.

      Registration of transfers and exchanges of capital securities will be
effected without charge by or on behalf of each Morgan Stanley Capital Trust,
but the property trustee may require payment to cover any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The Morgan Stanley Capital Trusts will not be required to register
or cause to be registered the transfer of, or exchange or to cause to be
exchanged, any capital securities that have been called for redemption.

Information Concerning the Property Trustee

      The property trustee, other than during the occurrence and continuance
of a capital securities event of default, undertakes to perform only those
duties specifically set forth in each trust agreement or provided by the Trust
Indenture Act and, after a capital securities event of default has occurred
that has not been cured or waived, must exercise the rights and powers vested
in it by the applicable trust agreement for the benefit of the holders of
trust securities using the same degree of care and skill as a prudent person
would exercise in the conduct of his or her own affairs. Subject to this
provision, the property trustee is under no obligation to exercise any of the
rights or powers vested in it by the applicable trust agreement, other than
those vested in it upon the occurrence of a capital securities event of
default, at the request of any holder of trust securities unless it is offered
reasonable indemnity against the costs, expenses and liabilities that might be
incurred in complying with the request or direction.

      For information concerning the relationships between The Bank of New
York, which will initially be the property trustee, and us, see "Description
of Junior Subordinated Debentures-Information Concerning the Indenture
Trustee."

Miscellaneous

      The administrators and the property trustee of each Morgan Stanley
Capital Trust are authorized and directed to conduct the affairs of, and to
operate, the applicable Morgan Stanley Capital Trust in such a way that the
Morgan Stanley Capital Trust will not be deemed to be an "investment company"
required to be registered under the Investment Company Act or taxed as a
corporation for United States federal income tax purposes and so that the
junior subordinated debentures owned by the Morgan Stanley Capital Trust will
be treated as indebtedness of Morgan Stanley for United States federal income
tax purposes. In this regard, the property trustee and the holders of common
securities are authorized to take any action, not inconsistent with applicable
law or the certificate of trust or the trust agreement of the applicable
Morgan Stanley Capital Trust, that the property trustee and the holders of
common securities determine in their discretion to be necessary or desirable
for those purposes, as long as the action does not materially adversely affect
the interests of the holders of the capital securities of the applicable
Morgan Stanley Capital Trust.

      Holders of the trust securities have no preemptive or similar rights.

      The Morgan Stanley Capital Trusts may not borrow money, issue debt or
mortgage or pledge any of their assets.

Governing Law

      Each trust agreement will be governed by, and construed in accordance
with, the laws of the State of Delaware.

                DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES

      The junior subordinated debentures will constitute junior subordinated
debt of Morgan Stanley and will be issued under a junior subordinated
indenture, dated October 1, 2004, entered into between us and The Bank of New



                                      14



York, as indenture trustee. The indenture contains, and the junior
subordinated debentures, when issued, will contain, additional important terms
and provisions. The indenture and the form of the junior subordinated
debentures are filed as exhibits to the registration statement that includes
this prospectus. The following summaries of certain provisions of the
indenture and the junior subordinated debentures do not purport to be complete
and are subject to the detailed provisions of the indenture and junior
subordinated debentures. Where appropriate, we use parentheses to refer you to
the particular sections of the indenture. Any reference to particular sections
or defined terms of the indenture in any statement under this heading
qualifies the entire statement and incorporates by reference the applicable
section or definition into that statement.

      This summary of the indenture and the junior subordinated debentures
relates to terms and conditions applicable to the junior subordinated
debentures generally. The particular terms of any series of junior
subordinated debentures will be summarized in the applicable prospectus
supplement. If indicated in the prospectus supplement, the terms of any series
may differ from the terms summarized below.

General

      Each series of junior subordinated debentures issued under the indenture
will, unless otherwise indicated in the applicable prospectus supplement, rank
equally with all other series of junior subordinated debentures issued under
the indenture and will be unsecured and subordinate and junior in right of
payment to the extent and in the manner set forth in the indenture to all
senior indebtedness of Morgan Stanley. See "-Subordination." Most of our
assets are owned by our subsidiaries. Therefore, our rights and the rights of
our creditors, including holders of junior subordinated debentures, to
participate in the assets of any subsidiary upon the subsidiary's liquidation
or recapitalization will be subject to the prior claims of the subsidiary's
creditors, except to the extent that we ourselves may be a creditor with
recognized claims against the subsidiary. In addition, dividends, loans and
advances to us from certain subsidiaries are restricted by legal requirements,
including (in the case of Morgan Stanley & Co. Incorporated and Morgan Stanley
DW Inc.) net capital requirements under the Securities Exchange Act of 1934
and under rules of certain exchanges and other regulatory bodies, and (in the
case of Discover Bank, a Delaware-chartered bank and our wholly-owned indirect
subsidiary, and other bank subsidiaries) by banking regulations. Except as
otherwise provided in the applicable prospectus supplement, the indenture does
not limit the incurrence or issuance of other secured or unsecured debt of
Morgan Stanley, including senior indebtedness, whether under the indenture,
any other existing indenture or any other indenture that Morgan Stanley may
enter into in the future, or otherwise afford holders of junior subordinated
debentures protection in the event of a highly leveraged or similar
transaction that may adversely affect the holders of the junior subordinated
debentures. See "-Subordination" and the applicable prospectus supplement
relating to any offering of capital securities or junior subordinated
debentures.

      We may issue junior subordinated debentures from time to time in one or
more series pursuant to a supplemental indenture or a resolution of our board
of directors or a committee of our board of directors.

      The applicable prospectus supplement will contain, where applicable, the
following terms of and other information relating to any offered junior
subordinated debentures:

      o     the title of the junior subordinated debentures;

      o     any limit upon the aggregate principal amount of the junior
            subordinated debentures;

      o     the date or dates on which the principal of the junior
            subordinated debentures is payable or the method of determination
            thereof, including the right or obligation, if any, of Morgan
            Stanley to shorten or extend the stated maturity date in certain
            circumstances;

      o     the rate or rates, if any, at which the junior subordinated
            debentures will bear interest, the dates on which that interest
            will be payable, the right or obligation, if any, of Morgan
            Stanley to defer or extend an interest payment date and, if
            applicable, the circumstances under which any such right or
            obligation will be exercisable or will arise and the record dates
            for any interest payable on any interest payment date or the
            method by which any of the foregoing will be determined;


                                      15





      o     the place or places where the principal of and premium, if any,
            and interest on the junior subordinated debentures will be payable
            and where, subject to the terms of the indenture as described
            below under "-Registration and Transfer of Junior Subordinated
            Debentures," the junior subordinated debentures may be presented
            for registration of transfer or exchange and the place or places
            where notices and demands to or upon Morgan Stanley in respect of
            the junior subordinated debentures and the indenture may be made;

      o     any period or periods within which, or date or dates on which, the
            price or prices at which and the terms and conditions upon which
            junior subordinated debentures may be redeemed, in whole or in
            part, at the option of Morgan Stanley or a holder of junior
            subordinated debentures;

      o     the obligation, if any, of Morgan Stanley to redeem, purchase or
            repay the junior subordinated debentures and the period or periods
            within which, the price or prices at which, and the other terms
            and conditions upon which the junior subordinated debentures will
            be redeemed, repaid or purchased, in whole or in part, pursuant to
            that obligation;

      o     the denominations in which any junior subordinated debentures will
            be issuable if other than denominations of $25 and any integral
            multiple of $25;

      o     if other than in U.S. dollars, the currency or currencies
            (including currency unit or units) in which the principal of (and
            premium, if any) and interest, if any, on the junior subordinated
            debentures will be payable, or in which the junior subordinated
            debentures will be denominated;

      o     if other than the principal amount, the portion of the principal
            amount of junior subordinated debentures that will be payable upon
            declaration of acceleration of maturity;

      o     any index or indices used to determine the amount of payments of
            principal of and premium, if any, and interest on the junior
            subordinated debentures and the manner in which those amounts will
            be determined;

      o     whether the junior subordinated debentures will be issuable in
            registered form or bearer form or both and, if bearer securities
            are issuable, any restrictions applicable to the exchange of one
            form for another and to the offer, sale and delivery of the bearer
            securities;

      o     any additions or changes to the indenture with respect to a series
            of junior subordinated debentures as will be necessary to permit
            or facilitate the issuance of that series in bearer form,
            registrable or not registrable as to principal, and with or
            without interest coupons;

      o     the appointment of any trustees, depositaries, authenticating or
            paying agents, transfer agents or registrars or other agents;

      o     whether the junior subordinated debentures will be convertible or
            exchangeable for other securities or property and, if so, the
            terms of any conversion or exchange and the terms of the other
            securities; and

      o     any other terms of the junior subordinated debentures, including
            any additions, modifications or deletions in the events of default
            or defaults under the indenture or covenants of Morgan Stanley
            specified in the indenture with respect to the junior subordinated
            debentures, and any terms required by or advisable under
            applicable laws or regulations.

Registration and Transfer of Junior Subordinated Debentures

      Holders may present junior subordinated debentures for exchange, and
holders of registered junior subordinated debentures may present these
securities for transfer, in the manner, at the places and subject to the
restrictions stated in the junior subordinated debentures and described in the
applicable prospectus supplement. We will provide these services without
charge except for any tax or other governmental charge payable in connection
with these services and subject to any limitations provided in the indenture.


                                      16






      Holders may transfer junior subordinated debentures in bearer form and
the related coupons, if any, by delivery to the transferee. If any of the
securities are held in global form, the procedures for transfer of interests
in those securities will depend upon the procedures of the depositary for
those global securities.

Subordination

      Holders of the junior subordinated debentures should recognize that
contractual provisions in the indenture may prohibit us from making payments
on these securities. The junior subordinated debentures are subordinate and
junior in right of payment, to the extent and in the manner stated in the
indenture, to all of our senior indebtedness. The indenture defines senior
indebtedness as obligations of, or guaranteed or assumed by, Morgan Stanley
for borrowed money or evidenced by bonds, debentures, notes or other similar
instruments, including obligations with respect to securities issued under the
senior indenture or the senior subordinated indentures of Morgan Stanley, and
amendments, renewals, extensions, modifications and refundings of any of that
indebtedness or of those obligations. Additional obligations may be included
in the definition of senior indebtedness pursuant to the supplemental
indenture under which a series of junior subordinated debentures is issued or
in the form of junior subordinated debenture for such series if we determine
that inclusion of such obligations is necessary in order to ensure that the
junior subordinated debentures receive the regulatory capital treatment
desired by us or as otherwise specified in an applicable prospectus
supplement. Nonrecourse obligations, the junior subordinated debentures and
any other obligations specifically designated as being subordinate in right of
payment to senior indebtedness are not senior indebtedness as defined under
the indenture.  (Section 1.01)

      The indenture does not restrict our ability to issue senior
indebtedness.

      The indenture provides that, unless all principal of and any premium or
interest on the senior indebtedness has been paid in full, or provision has
been made to make these payments in full, no payment of principal of, or any
premium or interest on, any junior subordinated debentures may be made in the
event:

      o     of any insolvency or bankruptcy proceedings, or any receivership,
            liquidation, reorganization or other similar proceedings involving
            us or a substantial part of our property;

      o     that (a) a default has occurred in the payment of principal, any
            premium, interest or other monetary amounts due and payable on any
            senior indebtedness or (b) there has occurred any other event of
            default concerning senior indebtedness, that permits the holder or
            holders of the senior indebtedness to accelerate the maturity of
            the senior indebtedness, with notice or passage of time, or both,
            and that event of default has continued beyond the applicable
            grace period, if any, and that default or event of default has not
            been cured or waived or has not ceased to exist; or

      o     that the principal of and accrued interest on any junior
            subordinated debentures have been declared due and payable upon an
            event of default as defined under the indenture and that
            declaration has not been rescinded and annulled as provided under
            the indenture. (Section 13.01)

      We currently have outstanding four series of junior subordinated
debentures, which were issued under a junior subordinated indenture, dated
March 1, 1998, between us and The Bank of New York and purchased,
respectively, by Morgan Stanley Capital Trust II, Morgan Stanley Capital Trust
III, Morgan Stanley Capital Trust IV and Morgan Stanley Capital Trust V (the
"existing junior subordinated debentures") with terms and conditions
substantially similar to those of the junior subordinated debentures described
in this prospectus. At August 31, 2005, there was $2,881 million aggregate
principal amount of such junior subordinated debentures outstanding. Those
junior subordinated debentures contain certain acceleration provisions that
could be triggered prior to the acceleration provisions of the junior
subordinated debentures described in this prospectus. Accordingly, the
outstanding amount of those four series of junior subordinated debentures
could become due and payable prior to the junior subordinated debentures
described in this prospectus. In addition, if the existing junior subordinated
debentures were to be included in the definition of senior indebtedness
pursuant to a supplemental indenture, the junior subordinated debentures
described in this prospectus would also be subordinate and junior in right of
payment, to the extent and in the manner stated in the indenture, to the
existing junior subordinated debentures.


                                      17





Merger, Consolidation, Sale, Lease or Conveyance

      The indenture provides that we will not merge or consolidate with any
other person and will not sell, lease or convey all or substantially all of
our assets to any other person, unless:

      o     we will be the continuing corporation; or

      o     the successor corporation or person that acquires all or
            substantially all of our assets:

            o     will be a corporation organized under the laws of the United
                  States, a state of the United States or the District of
                  Columbia; and

            o     will expressly assume all of our obligations under the
                  indenture and the junior subordinated debentures issued
                  under the indenture; and

      o     immediately after the merger, consolidation, sale, lease or
            conveyance, we, that person or that successor corporation will not
            be in default in the performance of the covenants and conditions
            of the indenture applicable to us. (Section 9.01)

      There are no covenants or other provisions in the indenture that would
afford holders of junior subordinated debentures additional protection in the
event of a recapitalization transaction, a change of control of Morgan Stanley
or a highly leveraged transaction. The merger covenant described above would
only apply if the recapitalization transaction, change of control or highly
leveraged transaction were structured to include a merger or consolidation of
Morgan Stanley or a sale, lease or conveyance of all or substantially all of
our assets. However, we may provide specific protections, such as a put right
or increased interest, for particular junior subordinated debentures, which we
would describe in the applicable prospectus supplement.

Events of Default and Defaults

      The indenture provides holders of junior subordinated debentures with
remedies if we fail to perform specific obligations, such as making payments
on the junior subordinated debentures, or if we become bankrupt. Holders
should review these provisions and understand which of our actions trigger an
event of default or a default and which actions do not. The indenture permits
the issuance of junior subordinated debentures in one or more series, and, in
many cases, whether an event of default or a default has occurred is
determined on a series by series basis.

      Events of Default

      An event of default is defined under the indenture, with respect to any
series of junior subordinated debentures issued under the indenture, as being:

      o     failure to pay in full the interest accrued on any junior
            subordinated debentures of that series upon the conclusion of an
            extension of the interest payment period of 20 consecutive
            quarters and continuance of that failure for a period of 30 days;

      o     events of bankruptcy, insolvency or reorganization; or

      o     any other event of default provided in a supplemental indenture
            under which the series of junior subordinated debentures is
            issued. (Section 5.01)

      Defaults

      A default is defined under the indenture, with respect to any series of
junior subordinated debentures issued under the indenture, as being:

      o     an event of default with respect to such series;

      o     default in payment of any principal of the junior subordinated
            debentures of that series, either at maturity or upon any
            redemption, by declaration or otherwise;



                                      18





      o     default for 30 days in payment of any interest on any junior
            subordinated debentures of that series, provided, however, that a
            valid extension of an interest payment period by Morgan Stanley in
            accordance with the terms of the junior subordinated debentures of
            any series will not constitute a default in the payment of
            interest for this purpose;

      o     default for 60 days after written notice in the observance or
            performance of any other covenant or agreement in the junior
            subordinated debentures of that series or the indenture (other
            than a covenant or warranty with respect to the junior
            subordinated debentures of that series the breach or
            nonperformance of which is otherwise included in the definition of
            "event of default" or "default"); or

      o     any other default provided in a supplemental indenture under which
            the series of junior subordinated debentures is issued. (Section
            5.06)

      Acceleration of Junior Subordinated Debentures upon an Event of Default
      and Other Remedies

      The indenture provides that:

      o     if an event of default due to the default in the payment of
            accrued interest on any series of junior subordinated debentures
            issued under the indenture occurs and is continuing, either the
            trustee or the holders of not less than 25% in aggregate principal
            amount of the outstanding junior subordinated debentures of each
            affected series, voting as one class, by notice in writing to
            Morgan Stanley, may declare the principal of all junior
            subordinated debentures of each affected series and interest
            accrued thereon to be due and payable immediately; and

      o     if an event of default due to specified events of bankruptcy,
            insolvency or reorganization of Morgan Stanley occurs and is
            continuing, either the trustee or the holders of not less than 25%
            in aggregate principal amount of all outstanding junior
            subordinated debentures issued under that indenture, voting as one
            class, by notice in writing to Morgan Stanley may declare the
            principal of all those junior subordinated debentures and interest
            accrued thereon to be due and payable immediately. (Section 5.01)

      There is no right of acceleration with respect to defaults, except for
those defaults that are also events of default. If a default in the payment of
principal of, or any interest on, any series of junior subordinated debentures
issued under the indenture occurs and is continuing and we fail to pay the
full amount then due and payable with respect to all junior subordinated
debentures of the affected series immediately upon the demand of the indenture
trustee, the indenture trustee is entitled to institute an action or
proceeding to collect the amount due and unpaid. (Section 5.02) If any default
occurs and is continuing, the indenture trustee may pursue legal action to
enforce the performance of any provision in the indenture to protect the
rights of the indenture trustee and the holders of the junior subordinated
debentures. (Section 5.04)

      Annulment of Acceleration and Waiver of Defaults

      In some circumstances, if any and all defaults under the indenture,
other than the non-payment of the principal of the securities that has become
due as a result of an acceleration, have been cured, waived or otherwise
remedied, then the holders of a majority in aggregate principal amount of all
series of outstanding junior subordinated debentures affected, voting as one
class, may waive past defaults of and annul past declarations of acceleration
of the junior subordinated debentures. (Section 5.01)

      Prior to the acceleration of any junior subordinated debentures, the
holders of a majority in aggregate principal amount of all series of
outstanding junior subordinated debentures with respect to which a default has
occurred and is continuing, voting as one class, may waive any past default,
other than a default in the payment of principal or interest (unless such
default has been cured and an amount sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the trustee) or a default in respect of a covenant or
provision in the indenture that cannot be modified or amended without the
consent of the holder of each junior subordinated debenture affected. (Section
5.10)


                                      19



      Indemnification of Trustee for Actions Taken on Your Behalf

      The indenture contains a provision entitling the indenture trustee,
subject to the duty of the indenture trustee during a default to act with the
required standard of care, to be indemnified by the holders of junior
subordinated debentures issued under that indenture before proceeding to
exercise any right or power at the request of holders. (Section 6.02) Subject
to these provisions and some other limitations, the holders of a majority in
aggregate principal amount of each series of outstanding junior subordinated
debentures of each affected series, voting as one class, may direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee, or exercising any trust or power conferred on the indenture trustee.
(Section 5.09)

      Limitation on Actions by You as an Individual Holder

      The indenture provides that no individual holder of junior subordinated
debentures may institute any action against us under that indenture, except
actions for payment of overdue principal and interest, unless the following
actions have occurred:

      o     the holder must have previously given written notice to the
            trustee of the continuing default;

      o     the holders of not less than 25% in aggregate principal amount of
            the outstanding junior subordinated debentures of each affected
            series, treated as one class, must have (1) requested the trustee
            to institute that action and (2) offered the indenture trustee
            reasonable indemnity;

      o     the indenture trustee must have failed to institute that action
            within 60 days after receipt of the request referred to above; and

      o     the holders of a majority in principal amount of the outstanding
            junior subordinated debentures of each affected series, voting as
            one class, must not have given directions to the indenture trustee
            inconsistent with those of the holders referred to above.
            (Sections 5.06 and 5.09)

      Annual Certification

      The indenture contains a covenant that we will file annually with the
indenture trustee a certificate of no default or a certificate specifying any
default that exists. (Section 3.05)

Discharge, Defeasance and Covenant Defeasance

      We have the ability to eliminate most or all of our obligations on any
series of junior subordinated debentures prior to maturity if we comply with
the following provisions. (Section 10.01)

      Discharge of Indenture

      If at any time we have:

      o     paid or caused to be paid the principal of and interest on all of
            the outstanding junior subordinated debentures of the series in
            accordance with their terms;

      o     delivered to the indenture trustee for cancellation all of the
            outstanding junior subordinated debentures of the series; or

      o     irrevocably deposited with the indenture trustee cash or, in the
            case of a series of junior subordinated debentures payable only in
            U.S. dollars, U.S. government obligations in trust for the benefit
            of the holders of any series of junior subordinated debentures
            issued under the indenture that have either become due and
            payable, or are by their terms due and payable within one year or
            are scheduled for redemption within one year in an amount
            certified to be sufficient to pay on each date that they become
            due and payable, the principal of and interest on, and any
            mandatory sinking fund payments for, those junior subordinated
            debentures;


                                      20






and if, in any such case, we also pay or cause to be paid all other sums
payable by us under the indenture with respect to the series of junior
subordinated debentures, then the indenture shall cease to be of further
effect with respect to the junior subordinated debentures of such series,
except as to certain rights with respect to the transfer and exchange of
securities, rights of the holders to receive payment and certain other rights.

      Defeasance of a Series of Securities at Any Time

      We may also discharge all of our obligations, other than as to transfers
and exchanges, under any series of junior subordinated debentures at any time,
which we refer to as "defeasance."

      We may be released with respect to any outstanding series of junior
subordinated debentures from the covenants described above limiting
consolidations, mergers, asset sales and leases, and elect not to comply with
that section without creating an event of default or a default. Discharge
under these procedures is called "covenant defeasance."

      Defeasance or covenant defeasance may be effected only if, among other
things:

      o     we irrevocably deposit with the indenture trustee cash or, in the
            case of junior subordinated debentures payable only in U.S.
            dollars, U.S. government obligations, as trust funds in an amount
            certified to be sufficient to pay on each date that they become
            due and payable, the principal of and interest on, and any
            mandatory sinking fund payments for, all outstanding junior
            subordinated debentures of the series being defeased;

      o     we deliver to the indenture trustee an opinion of counsel to the
            effect that:

            o     the holders of the series of junior subordinated debentures
                  being defeased will not recognize income, gain or loss for
                  United States federal income tax purposes as a result of the
                  defeasance or covenant defeasance; and

            o     the defeasance or covenant defeasance will not otherwise
                  alter those holders' United States federal income tax
                  treatment of principal and interest payments on the series
                  of junior subordinated debentures being defeased;

in the case of a defeasance, this opinion must be based on a ruling of the
Internal Revenue Service or a change in United States federal income tax law
occurring after the date of this prospectus, since that result would not occur
under current tax law;

      o     no event or condition will exist that, under the provisions
            described under "-Subordination" above, would prevent us from
            making payments of principal or interest on the junior
            subordinated debentures at the date of the irrevocable deposit
            referred to above or at any time during the period ending on the
            91st day after that deposit date; and

      o     we deliver to the indenture trustee an opinion of counsel to the
            effect that:


            o     the trust funds will not be subject to any rights of holders
                  of senior indebtedness; and

            o     after the 91st day following the deposit, the trust funds
                  will not be subject to any applicable bankruptcy,
                  insolvency, reorganization or similar laws affecting
                  creditors' rights generally, except that if a court were to
                  rule under any of those laws in any case or proceeding that
                  the trust funds remained our property, then the indenture
                  trustee and the holders of the junior subordinated
                  debentures would be entitled to some enumerated rights as
                  secured creditors in the trust funds. (Section 10.01)


Modification of Indenture

      Modification Without Consent of Holders

      We and the indenture trustee may enter into supplemental indentures
without the consent of the holders of junior subordinated debentures to:


                                      21





      o     secure any junior subordinated debentures;

      o     evidence the assumption of our obligations by a successor
            corporation;

      o     add covenants for the protection of the holders of junior
            subordinated debentures;

      o     cure any ambiguity or correct any inconsistency in the indenture;

      o     establish the forms or terms of junior subordinated debentures of
            any series; and

      o     evidence the acceptance of appointment by a successor indenture
            trustee. (Section 8.01)

      Modification with Consent of Holders

      We and the trustee, with the consent of the holders of not less than a
majority in aggregate principal amount of each affected series of outstanding
junior subordinated debentures, voting as one class, may add any provisions
to, or change in any manner or eliminate any of the provisions of, the
indenture or modify in any manner the rights of the holders of those junior
subordinated debentures. However, except as specified in the applicable
prospectus supplement, we and the trustee may not make any of the following
changes to any outstanding junior subordinated debenture without the consent
of each holder that would be affected by such change:

      o     extend the final maturity of the principal;

      o     reduce the principal amount;

      o     reduce the rate or extend the time of payment of interest;

      o     reduce any amount payable on redemption;

      o     change the currency in which the principal, including any amount
            of original issue discount, premium, or interest thereon is
            payable;

      o     reduce the amount of any original issue discount security payable
            upon acceleration or provable in bankruptcy;

      o     alter certain provisions of the indenture relating to the junior
            subordinated debentures not denominated in U.S. dollars;

      o     impair the right of any holder to institute suit for the
            enforcement of any payment on any junior subordinated debenture
            when due; or

      o     reduce the percentage of junior subordinated debentures the
            consent of whose holders is required for modification of the
            indenture.

      If the junior subordinated debentures are owned by a Morgan Stanley
Capital Trust, none of the modifications described above may be made without
the prior written consent of all the holders of capital securities of the
Morgan Stanley Capital Trust. (Section 8.02)

      Modification of Subordination Provisions

      We may not amend the indenture to alter the subordination of any
outstanding junior subordinated debentures without the written consent of each
potentially adversely affected holder of senior indebtedness then outstanding.
(Section 8.06)

Information Concerning the Indenture Trustee

      We and our subsidiaries maintain credit facilities and other ordinary
banking relationships with The Bank of New York.


                                      22




Governing Law

      The junior subordinated debentures and the indenture will be governed
by, and construed in accordance with, the laws of the State of New York.


                       DESCRIPTION OF GLOBAL SECURITIES

      We may issue the registered junior subordinated debentures and capital
securities in the form of one or more fully registered global securities that
will be deposited with a depositary or its nominee identified in the
applicable prospectus supplement and registered in the name of that depositary
or its nominee. In those cases, one or more registered global securities will
be issued in a denomination or aggregate denominations equal to the portion of
the aggregate principal or face amount of the securities to be represented by
registered global securities. Unless and until it is exchanged in whole for
securities in definitive registered form, a registered global security may not
be transferred except as a whole by and among the depositary for the
registered global security, the nominees of the depositary or any successors
of the depositary or those nominees.

      The specific terms of the depositary arrangement with respect to any
portion of a series of securities to be represented by a registered global
security will be described in the prospectus supplement relating to that
series. We anticipate that the following provisions will apply to all
depositary arrangements.

      Ownership of beneficial interests in a registered global security will
be limited to persons, called participants, that have accounts with the
depositary or persons that may hold interests through participants. Upon the
issuance of a registered global security, the depositary will credit, on its
book-entry registration and transfer system, the participants' accounts with
the respective principal or face amounts of the securities beneficially owned
by the participants. Any dealers, underwriters or agents participating in the
distribution of the securities will designate the accounts to be credited.
Ownership of beneficial interests in a registered global security will be
shown on, and the transfer of ownership interests will be effected only
through, records maintained by the depositary, with respect to interests of
participants, and on the records of participants, with respect to interests of
persons holding through participants. The laws of some states may require that
some purchasers of securities take physical delivery of these securities in
definitive form. These laws may impair your ability to own, transfer or pledge
beneficial interests in registered global securities.

      So long as the depositary, or its nominee, is the registered owner of a
registered global security, that depositary or its nominee, as the case may
be, will be considered the sole owner or holder of the securities represented
by the registered global security for all purposes under the indenture. Except
as described below, owners of beneficial interests in a registered global
security will not be entitled to have the securities represented by the
registered global security registered in their names, will not receive or be
entitled to receive physical delivery of the securities in definitive form and
will not be considered the owners or holders of the securities under the
indenture. Accordingly, each person owning a beneficial interest in a
registered global security must rely on the procedures of the depositary for
that registered global security and, if that person is not a participant, on
the procedures of the participant through which the person owns its interest,
to exercise any rights of a holder under the indenture. We understand that
under existing industry practices, if we request any action of holders or if
an owner of a beneficial interest in a registered global security desires to
give or take any action that a holder is entitled to give or take under the
indenture, the depositary for the registered global security would authorize
the participants holding the relevant beneficial interests to give or take
that action, and the participants would authorize beneficial owners owning
through them to give or take that action or would otherwise act upon the
instructions of beneficial owners holding through them.

      Payments of principal of, and premium, if any, and interest on, junior
subordinated debentures, and any payments to holders with respect to capital
securities, represented by a registered global security registered in the name
of a depositary or its nominee will be made to the depositary or its nominee,
as the case may be, as the registered owner of the registered global security.
None of Morgan Stanley, the indenture trustee, the Delaware trustee, the
property trustee or any other agent of Morgan Stanley, agent of the applicable
Morgan Stanley Capital Trust or agent of any of the aforementioned trustees,
as the case may be, will have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests in the registered


                                      23





global security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

      We and the Morgan Stanley Capital Trusts expect that the depositary for
any securities represented by a registered global security, upon receipt of
any payment of principal, premium, interest or other distribution with respect
to underlying securities to holders in respect of the registered global
security, will immediately credit participants' accounts in amounts
proportionate to their respective beneficial interests in the registered
global security as shown on the records of the depositary. We and the Morgan
Stanley Capital Trusts also expect that payments by participants to owners of
beneficial interests in the registered global security held through
participants will be governed by standing customer instructions and customary
practices, as is now the case with the securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of those participants.

      If the depositary for any securities represented by a registered global
security is at any time unwilling or unable to continue as depositary or
ceases to be a clearing agency registered under the Securities Exchange Act of
1934, and a successor depositary registered as a clearing agency under the
Securities Exchange Act of 1934 is not appointed by us or the applicable
Morgan Stanley Capital Trust, as the case may be, within 90 days, we or the
applicable Morgan Stanley Capital Trust, as the case may be, will issue the
securities in definitive form in exchange for the registered global security.
In addition, we or the applicable Morgan Stanley Capital Trust, as the case
may be, may at any time and in our sole discretion determine not to have any
of the securities of a series represented by one or more registered global
securities. We understand, however, that, under current industry practices,
the depositary would notify its participants of our request, but will only
withdraw beneficial interests from a global security at the request of each
participant. We would issue definitive certificates in exchange for any such
interests withdrawn. Any securities issued in definitive form in exchange for
a registered global security will be registered in the name or names as the
depositary instructs the relevant trustee or other relevant agent of Morgan
Stanley, the applicable Morgan Stanley Capital Trust or that trustee. It is
expected that those instructions will be based upon directions received by the
depositary from participants with respect to ownership of beneficial interests
in the registered global security.

      The securities may also be issued in the form of one or more bearer
global securities that will be deposited with a common depositary for
Euroclear Bank S.A./N.V., as operator of the Euroclear System, and Clearstream
Banking, socit anonyme, or with a nominee for the depositary identified in the
prospectus supplement relating to those securities. The specific terms and
procedures, including the specific terms of the depositary arrangement, with
respect to any securities to be represented by a bearer global security will
be described in the prospectus supplement relating to those securities.

                          DESCRIPTION OF GUARANTEES

      Morgan Stanley will execute and deliver a guarantee concurrently with
the issuance by each Morgan Stanley Capital Trust of its capital securities
for the benefit of the holders from time to time of those capital securities.
The guarantee trustee will hold the guarantee for the benefit of the holders
of the related Morgan Stanley Capital Trust's capital securities. Morgan
Stanley will qualify each of the guarantees as an indenture under the Trust
Indenture Act. The guarantees will be subject to, and governed by, the Trust
Indenture Act. This summary of certain provisions of the guarantees does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, all the provisions of each guarantee, including the definitions
of terms, and those provisions made part of each guarantee by the Trust
Indenture Act. A form of guarantee is filed as an exhibit to the registration
statement that includes this prospectus. A copy of the form of the guarantee
is available upon request from the guarantee trustee. If indicated in the
applicable prospectus supplement, the terms of a particular guarantee may
differ from the terms discussed below.

General

      Morgan Stanley will irrevocably and unconditionally agree to pay in
full, to the extent set forth in the guarantee, the guarantee payments to the
holders of the capital securities covered by the guarantee, as and when due,
regardless of any defense, right of set-off or counterclaim that the Morgan
Stanley Capital Trust that issued the capital securities may have or assert
other than the defense of payment. The following payments constitute guarantee


                                      24





payments with respect to capital securities that, to the extent not paid by or
on behalf of the Morgan Stanley Capital Trust, will be subject to the
applicable guarantee:

      o     any accumulated and unpaid distributions required to be paid on
            the applicable capital securities, to the extent that the
            applicable Morgan Stanley Capital Trust has funds on hand
            available for that purpose at that time;

      o     the applicable redemption price with respect to any capital
            securities called for redemption, which will include all
            accumulated and unpaid distributions to but excluding the date of
            redemption, to the extent that the applicable Morgan Stanley
            Capital Trust has funds on hand available for that purpose at that
            time; and

      o     upon a voluntary or involuntary dissolution, winding-up or
            liquidation of the applicable Morgan Stanley Capital Trust (unless
            the junior subordinated debentures owned by the Morgan Stanley
            Capital Trust are distributed to holders of the capital securities
            in accordance with the terms of the applicable trust agreement),
            the lesser of:

            o     the aggregate of the liquidation amount and all accumulated
                  and unpaid distributions to the date of payment, and

            o     the amount of assets of the applicable Morgan Stanley
                  Capital Trust remaining available for distribution to
                  holders of capital securities on liquidation of the Morgan
                  Stanley Capital Trust.

      Our obligation to make a guarantee payment may be satisfied by direct
payment of the required amounts by us to the holders of the capital securities
or by causing the applicable Morgan Stanley Capital Trust to pay those amounts
to the holders.

      Each guarantee will be an irrevocable guarantee of the related Morgan
Stanley Capital Trust's payment obligations described above under the capital
securities covered by the guarantee, but will apply only to the extent that
the Morgan Stanley Capital Trust has funds sufficient to make such payments,
and is not a guarantee of collection.

      If we do not make payments on the junior subordinated debentures owned
by a Morgan Stanley Capital Trust, the Morgan Stanley Capital Trust will not
be able to pay any amounts payable in respect of its capital securities and
will not have funds legally available for that purpose. In that event, holders
of the capital securities would not be able to rely upon the guarantee for
payment of those amounts. Each guarantee will have the same ranking as the
junior subordinated debentures owned by the Morgan Stanley Capital Trust that
issues the capital securities covered by the guarantee. See "-Status of the
Guarantees." No guarantee will limit the incurrence or issuance of other
secured or unsecured debt of Morgan Stanley.

Status of the Guarantees

      Each guarantee will constitute an unsecured obligation of Morgan Stanley
and will rank equal to the junior subordinated debentures owned by the Morgan
Stanley Capital Trust that issues the capital securities covered by the
guarantee.

      Each guarantee will constitute a guarantee of payment and not of
collection. Any holder of capital securities covered by the guarantee may
institute a legal proceeding directly against us to enforce its rights under
the guarantee without first instituting a legal proceeding against any other
person or entity. Each guarantee will be held by the guarantee trustee for the
benefit of the holders of the related capital securities. Each guarantee will
not be discharged except by payment of the guarantee payments in full to the
extent not paid by or on behalf of the Morgan Stanley Capital Trust or, if
applicable, distribution to the holders of the capital securities of the
junior subordinated debentures owned by the Morgan Stanley Capital Trust.

Amendments and Assignment

    Except with respect to any changes that do not materially adversely affect
the rights of holders of the capital securities issued by the Morgan Stanley
Capital Trust, in which case no approval will be required, the guarantee that



                                      25





covers the capital securities may not be amended without the prior approval of
the holders of at least a majority of the aggregate liquidation amount of the
outstanding capital securities covered by the guarantee. The manner of
obtaining any such approval will be as set forth under "Description of Capital
Securities-Voting Rights; Amendment of Trust Agreements" and in the applicable
prospectus supplement. All guarantees and agreements contained in each
guarantee will bind the successors, assigns, receivers, trustees and
representatives of Morgan Stanley and will inure to the benefit of the holders
of the then outstanding capital securities covered by the guarantee.

Events of Default

      An event of default under a guarantee will occur upon the failure of
Morgan Stanley to perform any of its payment obligations under that guarantee,
or to perform any non-payment obligation if the non-payment default remains
unremedied for 30 days. If an event of default under a guarantee occurred and
is continuing, the guarantee trustee will enforce the guarantee for the
benefit of the holders of capital securities covered by the guarantee. The
holders of a majority in aggregate liquidation amount of the outstanding
capital securities covered by the guarantee have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
guarantee trustee in respect of the guarantee or to direct the exercise of any
right or power conferred upon the guarantee trustee under the guarantee.


      Any holder of capital securities covered by the guarantee may institute
a legal proceeding directly against Morgan Stanley to enforce its rights under
the guarantee without first instituting a legal proceeding against the
applicable Morgan Stanley Capital Trust, the guarantee trustee or any other
person or entity.

      We, as guarantor, are required to file annually with the guarantee
trustee a certificate as to whether or not we are in compliance with all the
conditions and covenants under the guarantee.

Information Concerning the Guarantee Trustee

      The guarantee trustee, other than during the occurrence and continuance
of an event of default under the guarantee, undertakes to perform only those
duties as are specifically set forth in the guarantee and, after the
occurrence of an event of default with respect to the guarantee that has not
been cured or waived, must exercise the rights and powers vested in it by the
guarantee using the same degree of care and skill as a prudent person would
exercise or use in the conduct of his or her own affairs. Subject to this
provision, the guarantee trustee is under no obligation to exercise any of the
rights or powers vested in it by the guarantee at the request of any holder of
the capital securities covered by the guarantee unless it is offered
reasonable indemnity, including reasonable advances requested by it, against
the costs, expenses and liabilities that might be incurred in complying with
the request or direction.

      For information concerning the relationship between The Bank of New
York, which will initially be the guarantee trustee, and Morgan Stanley, see
"Description of Junior Subordinated Debentures-Information Concerning the
Indenture Trustee."

Termination of the Guarantee

      Each guarantee will terminate upon full payment of the redemption price
of all of the capital securities covered by the guarantee, upon full payment
of the amounts payable with respect to the capital securities upon liquidation
of the related Morgan Stanley Capital Trust or upon distribution of the junior
subordinated debentures owned by the Morgan Stanley Capital Trust to the
holders of all the capital securities covered by the guarantee. Each guarantee
will continue to be effective or will be reinstated, as the case may be, if at
any time any holder of the capital securities covered by the guarantee must
repay any sums with respect to the capital securities or the guarantee.

Governing Law

      Each guarantee will be governed by, and construed in accordance with,
the laws of the State of New York.


                                      26




                             PLAN OF DISTRIBUTION

      We may sell junior subordinated debentures and a Morgan Stanley Capital
Trust may sell capital securities in three ways: (1) through agents, (2)
through underwriters and (3) through dealers. The agents, underwriters or
dealers in the United States will include Morgan Stanley & Co. Incorporated,
which we refer to as MS & Co., and/or Morgan Stanley DW Inc., which we refer
to as MSDWI, or other affiliates of ours, and the agents, underwriters or
dealers outside the United States will include Morgan Stanley & Co.
International Limited, which we refer to as MSIL, or other affiliates of ours.

      We and/or the applicable Morgan Stanley Capital Trust may designate
agents from time to time to solicit offers to purchase these securities. We
will name any such agent, who may be deemed to be an underwriter as that term
is defined in the Securities Act of 1933, and state any commissions we are to
pay to that agent in the applicable prospectus supplement. That agent will be
acting on a reasonable efforts basis for the period of its appointment or, if
indicated in the applicable prospectus supplement, on a firm commitment basis.

      If any underwriters are utilized in the sale of these securities, we
and/or the applicable Morgan Stanley Capital Trust, as the case may be, will
enter into an underwriting agreement with the underwriters at the time of sale
to them and the names of the underwriters and the terms of the transaction
will be set forth in the applicable prospectus supplement, which will be used
by the underwriters to make resales of the securities in respect of which this
prospectus is delivered to the public.

      If a dealer is utilized in the sale of these securities, we and/or the
applicable Morgan Stanley Capital Trust, as the case may be, will sell the
securities to the dealer, as principal, and will name the dealer in the
applicable prospectus supplement. The dealer may then resell the securities to
the public at varying prices to be determined by such dealer at the time of
resale.

      In order to facilitate the offering of these securities, the
underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of these securities or any other securities the prices of
which may be used to determine payments on these securities. Specifically, the
underwriters may sell more securities than they are obligated to purchase in
connection with the offering, creating a short position for their own
accounts. A short sale is covered if the short position is no greater than the
number or amount of securities available for purchase by the underwriters
under any overallotment option. The underwriters can close out a covered short
sale by exercising the overallotment option or purchasing these securities in
the open market. In determining the source of securities to close out a
covered short sale, the underwriters will consider, among other things, the
open market price of these securities compared to the price available under
the overallotment option. The underwriters may also sell these securities or
any other securities in excess of the overallotment option, creating a naked
short position. The underwriters must close out any naked short position by
purchasing securities in the open market. A naked short position is more
likely to be created if the underwriters are concerned that there may be
downward pressure on the price of these 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 underwriters may bid
for, and purchase, these securities or any other securities in the open market
to stabilize the price of these securities or of any other securities.
Finally, in any offering of the securities through a syndicate of underwriters
or dealer group, the agent acting on behalf of the underwriting syndicate or
for itself may also reclaim selling concessions allowed to an underwriter or a
dealer for distributing these securities in the offering, if the agent
repurchases previously distributed securities to cover syndicate short
positions or to stabilize the price of these securities. Any of these
activities may raise or maintain the market price of these securities above
independent market levels or prevent or retard a decline in the market price
of these securities. The underwriters are not required to engage in these
activities and may end any of these activities at any time.

      If so indicated in the applicable prospectus supplement, one or more
firms, including MS & Co., MSDWI and MSIL, which we refer to as "remarketing
firms," acting as principals for their own accounts or as agents for us and/or
a Morgan Stanley Capital Trust, as the case may be, may offer and sell these
securities as part of a remarketing upon their purchase, in accordance with
their terms. We will identify any remarketing firm, the terms of its
agreement, if any, with us and/or a Morgan Stanley Capital Trust, as the case
may be, and its compensation in the applicable prospectus supplement.


                                      27





      Remarketing firms, agents, underwriters and dealers may be entitled
under agreements with us and/or a Morgan Stanley Capital Trust to
indemnification by us and/or a Morgan Stanley Capital Trust, against some
civil liabilities, including liabilities under the Securities Act of 1933, and
may be customers of, engage in transactions with, or perform services for, us
and/or a Morgan Stanley Capital Trust in the ordinary course of business.

      If so indicated in the applicable prospectus supplement, we and/or a
Morgan Stanley Capital Trust will authorize agents, underwriters or dealers to
solicit offers by some purchasers to purchase these securities from us at the
public offering price stated in the prospectus supplement under delayed
delivery contracts providing for payment and delivery on a specified date in
the future. These contracts will be subject to only those conditions described
in the applicable prospectus supplement, and the prospectus supplement will
state the commission payable for solicitation of these offers.

      Any underwriter, agent or dealer utilized in the initial offering of
securities will not confirm sales to accounts over which it exercises
discretionary authority without the prior specific written approval of its
customer.

      MS & Co., MSDWI and MSIL are wholly-owned subsidiaries of Morgan
Stanley. Each initial offering of securities will be conducted in compliance
with the requirements of Rule 2720 of the Conduct Rules of the National
Association of Securities Dealers, Inc., which is commonly referred to as the
NASD, regarding a NASD member firm's distributing the securities of an
affiliate. Following the initial distribution of any of these securities, MS &
Co., MSDWI, MSIL and other affiliates of Morgan Stanley may offer and sell
these securities in the course of their business as broker-dealers, subject to
obtaining any necessary approval of the New York Stock Exchange, Inc. for any
of the offers and sales. MS & Co., MSDWI, MSIL and other affiliates may act as
principals or agents in these transactions and may make any sales at varying
prices related to prevailing market prices at the time of sale or otherwise.
MS & Co., MSDWI, MSIL and other affiliates may use this prospectus in
connection with these transactions. None of MS & Co., MSDWI, MSIL or any other
affiliate is obligated to make a market in any of these securities and may
discontinue any market-making activities at any time without notice.

      In the event that MS & Co., MSDWI or any other NASD member participates
in a public offering of these securities: (a) post-effective amendments or
prospectus supplements disclosing the actual price and selling terms will be
submitted to the NASD's Corporate Financing Department (the "Department") at
the same time they are filed with the SEC; (b) the Department will be advised
if, subsequent to the filing of the offering, any 5% or greater shareholder of
ours is or becomes an affiliate or associated person of an NASD member
participating in the distribution; and (c) all NASD members participating in
the offering will confirm their understanding of the requirements that have to
be met in connection with SEC Rule 415 and Notice-to-Members 88-101.
Underwriting discounts and commissions on securities sold in the initial
distribution will not exceed 8% of the offering proceeds.

                                LEGAL MATTERS

      The validity of the capital securities will be passed upon for the
Morgan Stanley Capital Trusts by Richards, Layton & Finger, P.A., or other
counsel who is satisfactory to MS & Co. and/or MSDWI, as the case may be, and
who may be an officer of Morgan Stanley. The validity of the junior
subordinated debentures and the guarantees will be passed upon for Morgan
Stanley by Sidley Austin Brown & Wood LLP, or other counsel who is
satisfactory to MS & Co. and/or MSDWI, as the case may be, and who may be an
officer of Morgan Stanley. Certain legal matters relating to the securities
will be passed upon for the underwriters by Davis Polk & Wardwell. Davis Polk
& Wardwell has in the past represented Morgan Stanley and continues to
represent Morgan Stanley and its affiliates on a regular basis and in a
variety of matters, including in connection with its private equity and
leveraged capital activities.

of Morgan Stanley and its subsidiaries, at November 30, 2004 and 2003 and for
each of the three fiscal years in the period ended November 30, 2004, and

Schedule I of Morgan Stanley's Annual Report on Form 10-K for the fiscal year
ended November 30, 2004, filed on February 11, 2005 ("2004 Form 10-K") and
Item 9A of the 2004 Form 10-K, respectively, have been audited by Deloitte &
Touche LLP, an independent registered public accounting firm, as stated in
their reports, which are incorporated herein by reference (which reports (1)
express an unqualified opinion on the financial statements and financial
statement schedule and include an explanatory paragraph referring to the
adoption of Statement of Financial Accounting Standards ("SFAS") No. 123
"Accounting for Stock-Based Compensation," as amended by SFAS No. 148
"Accounting for Stock-Based Compensation?Transition and Disclosure, an
amendment of FASB Statement No. 123," in 2003, (2) express an unqualified
opinion on management's assessment regarding the effectiveness of internal
control over financial reporting, and (3) express an unqualified opinion on
the effectiveness of internal control over financial reporting), and have been
so included in reliance upon the respective reports of such firm given upon
their authority as experts in accounting and auditing.

      With respect to the unaudited interim financial information for the
periods ended February 28, 2005 and February 29, 2004, May 31, 2005 and May
31, 2004 and August 31, 2005 and August 31, 2004, which is incorporated herein
by reference, Deloitte & Touche LLP, an independent registered public
accounting firm, have applied limited procedures in accordance with standards
of the Public Company Accounting Oversight Board (United States) for a review
of such information. However, as stated in their reports included in Morgan
Stanley's Quarterly Report on Form 10-Q for the quarterly period ended August
31, 2005 and in Exhibits 99.2 and 99.3 to the Current Report on Form 8-K filed
October 12, 2005, and incorporated by reference herein, they did not audit and
they do not express an opinion on such interim financial information.
Accordingly, the degree of reliance on their reports on such information
should be restricted in light of the limited nature of the review procedures
applied. Deloitte & Touche LLP are not subject to the liability provisions of
Section 11 of the Securities Act of 1933 for their reports on the unaudited
interim financial information because those reports are not "reports" or a
"part" of the registration statement prepared or certified by an accountant
within the meaning of Sections 7 and 11 of the Securities Act of 1933.
