-------------------------------------------------------------------------------

      Morgan Stanley (formerly known as Morgan Stanley Dean Witter & Co.), a
Delaware corporation (together with its successors and assigns, the "Issuer"),
for value received, hereby promises to pay to bearer, upon surrender hereof,
the principal amount specified in Schedule A hereto, on the Maturity Date
specified above (except to the extent previously redeemed or repaid) and to pay
interest thereon at the Interest Rate per annum specified above from and
including the Interest Accrual Date specified above until but excluding the
date the principal amount is paid or duly made available for payment (except as
provided below), weekly, monthly, quarterly, semi-annually or annually in
arrears on the Interest Payment Dates specified above in each year commencing
on the Interest Payment Date next succeeding the Interest Accrual Date
specified above, and at maturity (or on any redemption or repayment date);
provided, however, that if the Interest Accrual Date occurs fifteen calendar
days or less prior to the first Interest Payment Date occurring after the
Interest Accrual Date, interest payments will commence on the second Interest
Payment Date succeeding the Interest Accrual Date.

      Interest on this Note 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 the
Interest Accrual Date, until but excluding the date the

(2)  Applicable if other than 30-60 calendar days. Consult with Euroclear or

principal amount hereof has been paid or duly made available for payment. Upon
any payment of interest on this Note, the Principal Paying Agent (as defined
below) shall cause Schedule A of this Note to be endorsed to reflect such
payment. No payment on this Note will be made at any office or agency of the
Issuer in the United States or by check mailed to an address in the United
States (as defined below) or by wire transfer to an account maintained by the
holder of this Note with a bank in the United States except as may be permitted
under United States federal tax laws and regulations then in effect without
adverse tax consequences to the Issuer. Notwithstanding the foregoing, in the
event that payment in U.S. dollars of the full amount payable on this Note at
the offices of all paying agents would be illegal or effectively precluded as a
result of exchange controls or similar restrictions, payment on this Note will
be made by a paying agency in the United States, if such paying agency, under
applicable law and regulations, would be able to make such payment.
Notwithstanding any other provision of this Note, no payment of principal or
interest shall be made on any portion of this Note unless there shall have been
delivered to the Principal Paying Agent a certificate substantially in the form
of Exhibit A hereto with respect to the portion of this Note with respect to
which such principal or interest is to be paid. Such certificate shall have
been delivered to the Principal Paying Agent by Euroclear Bank S.A./N.V., as
operator of the Euroclear System ("Euroclear"), and Clearstream Banking,
societe anonyme ("Clearstream, Luxembourg"), and/or any other relevant clearing
system (including Euroclear France) as the case may be, and shall be based on a
certificate substantially in the form of Exhibit B hereto provided to
Euroclear, Clearstream, Luxembourg and/or any other relevant clearing system,
as the case may be, by those of its account holders who are to receive such
payment of principal or interest.

      This Note is issued in temporary global bearer form and represents all or
a portion of a duly authorized issue of Global Medium-Term Notes, Series [D/E]
(the "Notes"), issued under an Amended and Restated Senior Indenture, dated as
of May 1, 1999, between the Issuer and JPMorgan Chase Bank (formerly known as
The Chase Manhattan Bank), as Trustee (the "Trustee," which term includes any
successor trustee under the Senior Indenture) (as may be amended or
supplemented from time to time, the "Senior Indenture"), to which Senior
Indenture and all indentures supplemental thereto reference is hereby made for
a statement of the respective rights, limitations of rights, duties and
immunities of the Issuer, the Trustee and holders of the Notes and the terms
upon which the Notes are, and are to be, authenticated and delivered. The
Issuer has appointed JPMorgan Chase Bank, London Branch, as its principal
paying agent for the Notes (the "Principal Paying Agent," which term includes
any additional or successor Principal Paying Agent appointed by the Issuer).

      Except as otherwise provided herein, this Note is governed by the terms
and conditions of the Permanent Global Fixed Rate Senior Bearer Note (the
"Permanent Global Bearer Note") to be issued in exchange for this Note, which
terms and conditions are hereby incorporated by reference herein mutatis
mutandis and shall be binding on the Issuer and the holder hereof as if fully
set forth herein. The form of the Permanent Global Bearer Note is attached
hereto.

      This Note is exchangeable in whole or from time to time in part on or
after the Exchange Date (as defined below) for an interest (equal to the
principal amount of the portion of this Note being exchanged) in a single
Permanent Global Bearer Note upon the request of Euroclear,


                                       3

Clearstream, Luxembourg and/or any other relevant clearing system, acting on
behalf of the owner of a beneficial interest in this Note, to the Principal
Paying Agent upon delivery to the Principal Paying Agent of a certificate
substantially in the form of Exhibit A hereto with respect to the portion of
this Note to be exchanged. Such certificate shall have been delivered to the
Principal Paying Agent by Euroclear, Clearstream, Luxembourg and/or any other
relevant clearing system, as the case may be, and shall be based on a
certificate substantially in the form of Exhibit B hereto provided to
Euroclear, Clearstream, Luxembourg and/or any other relevant clearing system,
as the case may be, by those of its account holders having an interest in the
portion hereof to be exchanged. Notwithstanding the foregoing, if this Note is
subject to a tax redemption as described on the reverse of the Permanent Global
Bearer Note attached hereto, interests in this Note may be exchanged for
interests in a Permanent Global Bearer Note on and after such redemption date
as if such redemption date had been the Exchange Date, subject to receipt of
the certificates described in the preceding sentence. Upon exchange of any
portion of this Note for an interest in a Permanent Global Bearer Note, the
Principal Paying Agent shall cause Schedule A of this Note to be endorsed to
reflect the reduction of its principal amount by an amount equal to the
aggregate principal amount being so exchanged. Except as otherwise provided
herein, until exchanged for a Permanent Global Bearer Note, this Note shall in
all respects be entitled to the same benefits under the Senior Indenture as a
duly authenticated and delivered Permanent Global Bearer Note.

      As used herein:

            (a) the term "Exchange Date" means the date that is 40 calendar
      days after the date on which the Issuer receives the proceeds of the sale
      of this Note (the "Closing Date"), provided that if an interest
      represented by this Note is held by Morgan Stanley & Co. International
      Limited, or any other manager participating in the distribution of the
      tranche of Notes of which this Note forms a part, as part of an unsold
      allotment or subscription more than 40 calendar days after the Closing
      Date for this Note, the Exchange Date with respect to such interest shall
      be the day after the date such interest is sold by Morgan Stanley & Co.
      International Limited or such other manager, all as determined and
      notified to the Trustee by Morgan Stanley & Co. International Limited or
      if Morgan Stanley & Co. International Limited did not participate in the
      distribution of such tranche, by the Issuer.

            (b) the term "United States" means the United States of America
      (including the States and the District of Columbia); and its
      "possessions" include Puerto Rico, the U.S. Virgin Islands, Guam,
      American Samoa, Wake Island and the Northern Mariana Islands.

      All other terms used in this Note which are defined in the Senior
Indenture and not otherwise defined herein shall have the meanings assigned to
them in the Senior Indenture.

      Unless the certificate of authentication hereon has been executed by the
Trustee by manual signature, this Note shall not be entitled to any benefit
under the Senior Indenture, as defined on the reverse hereof, or be valid or
obligatory for any purpose.
