                              If the Final Call Notice Date is postponed
                              because it is not a Trading Day or due to a

                              Issuer exercises the Morgan Stanley Call Right,
                              the Maturity Date shall be postponed so that the

                              two Business Days following the scheduled Final

                              the Trustee by first class mail, postage prepaid,
                              at its New York office and (iii) to The

                              the holder of this SPARQS receives the notice.

                              been rescheduled as a result of postponement of
                              the Final Call Notice Date, if applicable, shall
                              be included in the Issuer's notice of exercise of
                              the Morgan Stanley Call Right.

                              If the scheduled Maturity Date is postponed due
                              to a Market Disruption Event or otherwise, the
                              Issuer shall pay interest on the Maturity Date as
                              postponed rather than on October 1, 2006, but no
                              interest will accrue on this SPARQS or on such
                              payment during the period from or after the
                              scheduled Maturity Date.

Record Date.................. Notwithstanding the definition of "Record Date"
                              on page 23 hereof, the Record Date for each
                              Interest Payment Date, including the Interest
                              Payment Date scheduled to occur on the Maturity
                              Date, shall be the date 5 calendar days prior to
                              such scheduled Interest Payment Date, whether or
                              not that date is a Business Day; provided,
                              however, that in the event that the Issuer
                              exercises the Morgan Stanley Call Right, no
                              Interest Payment Date shall occur after the
                              Morgan Stanley Notice Date, except for any
                              Interest Payment Date for which the Morgan
                              Stanley Notice Date falls on or after the
                              "ex-interest" date for the related interest
                              payment, in which case the related interest
                              payment shall be made on such Interest Payment
                              Date; and provided, further, that accrued but
                              unpaid interest payable on the Call Date, if any,
                              shall be payable to the person to whom the Call
                              Price is payable. The "ex-interest" date for any
                              interest payment is the date on which purchase
                              transactions in the SPARQS no longer carry the
                              right to receive such interest payment.

                              In the event that the Issuer exercises the Morgan
                              Stanley Call Right and the Morgan Stanley Notice
                              Date falls before the "ex-interest" date for an
                              interest payment, so that as a result a scheduled
                              Interest Payment Date will not occur, the Issuer
                              shall cause the Calculation Agent to give notice
                              to the Trustee and to the Depositary, in each
                              case in the manner and at the time described in
                              the second and third paragraphs under "Morgan
                              Stanley Call Right" below, that no Interest
                              Payment Date will occur after such Morgan Stanley
                              Notice Date.

Morgan Stanley Call Right.... On any scheduled Trading Day on or after April 1,
                              2006 or on the Maturity Date (including the
                              Maturity Date as it may be extended and
                              regardless of whether the Maturity Date is a
                              Trading Day), the Issuer may call the SPARQS, in
                              whole but not in part, for mandatory exchange for
                              the Call Price paid in cash (together with

                              On the Morgan Stanley Notice Date, the Issuer
                              shall give notice of the Issuer's exercise of the

                              provided shall be conclusively presumed to have
                              been duly given, whether or not the holder of
                              this SPARQS receives the notice. Failure to give
                              notice by mail or any defect in the notice to the
                              holder of any SPARQS shall not affect the

                              the Morgan Stanley Call Right with respect to any
                              other SPARQS.

                              The notice of the Issuer's exercise of the Morgan
                              Stanley Call Right shall specify (i) the Call
                              Date, (ii) the Call Price payable per SPARQS,
                              (iii) the amount of accrued but unpaid interest
                              payable per SPARQS on the Call Date, (iv) whether
                              any subsequently scheduled Interest Payment Date
                              shall no longer be an Interest Payment Date as a
                              result of the exercise of the Morgan Stanley Call
                              Right, (v) the place or places of payment of such

                              (vii) that such exchange is pursuant to the

                              applicable, the date to which the Maturity Date
                              has been extended due to a Market Disruption
                              Event as described under "Maturity Date" above.

     Morgan Stanley, a Delaware corporation (together with its successors and
assigns, the "Issuer"), for value received, hereby promises to pay to CEDE &
CO., or registered assignees, the amount of National Oilwell Varco Stock (or
other Exchange Property), as determined in accordance with the provisions set
forth under "Exchange at Maturity" above, due with respect to the principal sum
of U.S. $               (UNITED STATES DOLLARS                 ) on the
Maturity Date specified above (except to the extent redeemed or repaid prior to
maturity) and to pay interest thereon at the Interest Rate per annum specified
above, from and including the Interest Accrual Date specified above until the
principal hereof is paid or duly made available for payment weekly, monthly,
quarterly, semiannually or annually in arrears as specified above as the
Interest Payment Period on each Interest Payment Date (as specified above),
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 between a Record
Date, as defined below, and the next succeeding Interest Payment Date, interest
payments will commence on the second Interest Payment Date succeeding the
Interest Accrual Date to the registered holder of this Note on the Record Date
with respect to such second Interest Payment Date; and provided, further, that
if this Note is subject to "Annual Interest Payments," interest payments shall
be made annually in arrears and the term "Interest Payment Date" shall be
deemed to mean the first day of March in each year.

     Interest on this Note will accrue from and including the most recent 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 principal hereof has been paid or duly made
available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, subject to certain exceptions
described herein, be paid to the person in whose name this Note (or one or more
predecessor Notes) is registered at the close of business on the date 15
calendar days prior to such Interest Payment Date (whether or not a Business
Day (as defined below)) (each such date, a "Record Date"); provided, however,
that interest payable at maturity (or any redemption or repayment date) will be
payable to the person to whom the principal hereof shall be payable. As used
herein, "Business Day" means any day, other than a Saturday or Sunday, (a) that
is neither a legal holiday nor a day on which banking institutions are
authorized or required by law or regulation to close (x) in The City of New
York or (y) if this Note is denominated in a Specified Currency other than U.S.
dollars, euro or Australian dollars, in the principal financial center of the

Express Transfer System ("TARGET") is operating (a "TARGET Settlement Day").

     Payment of the principal of this Note, any premium and the interest due at
maturity (or any redemption or repayment date), unless this Note is denominated
in a Specified Currency other than U.S. dollars and is to be paid in whole or
in part in such Specified Currency, will be made in immediately available funds
upon surrender of this Note at the office or agency of the Paying Agent, as
defined on the reverse hereof, maintained for that purpose in the Borough of
Manhattan, The City of New York, or at such other paying agency as the Issuer
may determine, in U.S. dollars. U.S. dollar payments of interest, other than
interest due at maturity or on any date of redemption or repayment, will be
made by U.S. dollar check mailed to the address of the

                                      23
<PAGE>

person entitled thereto as such address shall appear in the Note register. A
holder of U.S. $10,000,000 (or the equivalent in a Specified Currency) or more
in aggregate principal amount of Notes having the same Interest Payment Date,
the interest on which is payable in U.S. dollars, shall be entitled to receive
payments of interest, other than interest due at maturity or on any date of
redemption or repayment, by wire transfer of immediately available funds if
appropriate wire transfer instructions have been received by the Paying Agent
in writing not less than 15 calendar days prior to the applicable Interest
Payment Date.

     If this Note is denominated in a Specified Currency other than U.S.
dollars, and the holder does not elect (in whole or in part) to receive payment
in U.S. dollars pursuant to the next succeeding paragraph, payments of
interest, principal or any premium with regard to this Note will be made by
wire transfer of immediately available funds to an account maintained by the
holder hereof with a bank located outside the United States if appropriate wire
transfer instructions have been received by the Paying Agent in writing, with
respect to payments of interest, on or prior to the fifth Business Day after
the applicable Record Date and, with respect to payments of principal or any
premium, at least ten Business Days prior to the Maturity Date or any
redemption or repayment date, as the case may be; provided that, if payment of
interest, principal or any premium with regard to this Note is payable in euro,
the account must be a euro account in a country for which the euro is the
lawful currency, provided, further, that if such wire transfer instructions are
not received, such payments will be made by check payable in such Specified
Currency mailed to the address of the person entitled thereto as such address
shall appear in the Note register; and provided, further, that payment of the
principal of this Note, any premium and the interest due at maturity (or on any
redemption or repayment date) will be made upon surrender of this Note at the
office or agency referred to in the preceding paragraph.

     If so indicated on the face hereof, the holder of this Note, if
denominated in a Specified Currency other than U.S. dollars, may elect to
receive all or a portion of payments on this Note in U.S. dollars by
transmitting a written request to the Paying Agent, on or prior to the fifth
Business Day after such Record Date or at least ten Business Days prior to the
Maturity Date or any redemption or repayment date, as the case may be. Such
election shall remain in effect unless such request is revoked by written
notice to the Paying Agent as to all or a portion of payments on this Note at
least five Business Days prior to such Record Date, for payments of interest,
or at least ten calendar days prior to the Maturity Date or any redemption or
repayment date, for payments of principal, as the case may be.

     If the holder elects to receive all or a portion of payments of principal
of, premium, if any, and interest on this Note, if denominated in a Specified
Currency other than U.S. dollars, in U.S. dollars, the Exchange Rate Agent (as
defined on the reverse hereof) will convert such payments into U.S. dollars. In
the event of such an election, payment in respect of this Note will be based
upon the exchange rate as determined by the Exchange Rate Agent based on the
highest bid quotation in The City of New York received by such Exchange Rate
Agent at approximately 11:00 a.m., New York City time, on the second Business
Day preceding the applicable payment date from three recognized foreign
exchange dealers (one of which may be the Exchange Rate Agent unless such
Exchange Rate Agent is an affiliate of the Issuer) for the purchase by the
quoting dealer of the Specified Currency for U.S. dollars for settlement on
such payment date in the amount of the Specified Currency payable in the
absence of such an election to such holder

                                      24
<PAGE>

and at which the applicable dealer commits to execute a contract. If such bid
quotations are not available, such payment will be made in the Specified
Currency. All currency exchange costs will be borne by the holder of this Note
by deductions from such payments.

     Reference is hereby made to the further provisions of this Note set forth
on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof 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.

     This Note is one of a duly authorized issue of Senior Global Medium-Term
Notes, Series F, having maturities more than nine months from the date of issue
(the "Notes") of the Issuer. The Notes are issuable under a Senior Indenture,
dated as of November 1, 2004, between the Issuer and JPMorgan Chase Bank, N.A.
(formerly known as JPMorgan Chase 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, N.A. at its corporate trust office in
The City of New York as the paying agent (the "Paying Agent," which term
includes any additional or successor Paying Agent appointed by the Issuer) with
respect to the Notes. The terms of individual Notes may vary with respect to
interest rates, interest rate formulas, issue dates, maturity dates, or
otherwise, all as provided in the Senior Indenture. To the extent not
inconsistent herewith, the terms of the Senior Indenture are hereby
incorporated by reference herein.

     Unless otherwise indicated on the face hereof, this Note will not be
subject to any sinking fund and, unless otherwise provided on the face hereof
in accordance with the provisions of the following two paragraphs, will not be
redeemable or subject to repayment at the option of the holder prior to
maturity.

     If so indicated on the face hereof, this Note may be redeemed in whole or
in part at the option of the Issuer on or after the Initial Redemption Date
specified on the face hereof on the terms set forth on the face hereof,
together with interest accrued and unpaid hereon to the date of redemption. If
this Note is subject to "Annual Redemption Percentage Reduction," the Initial
Redemption Percentage indicated on the face hereof will be reduced on each
anniversary of the Initial Redemption Date by the Annual Redemption Percentage
Reduction specified on the face hereof until the redemption price of this Note
is 100% of the principal amount hereof, together with interest accrued and
unpaid hereon to the date of redemption. Notice of redemption shall be mailed
to the registered holders of the Notes designated for redemption at their
addresses as the same shall appear on the Note register not less than 30 nor
more than 60 calendar days prior to the date fixed for redemption or within the
Redemption Notice Period specified on the face hereof, subject to all the
conditions and provisions of the Senior Indenture. In the event of redemption
of this Note in part only, a new Note or Notes for the amount of the unredeemed
portion hereof shall be issued in the name of the holder hereof upon the
cancellation hereof.

     If so indicated on the face of this Note, this Note will be subject to
repayment at the option of the holder on the Optional Repayment Date or Dates
specified on the face hereof on the terms set forth herein. On any Optional
Repayment Date, this Note will be repayable in whole or in part in increments
of $1,000 or, if this Note is denominated in a Specified Currency other than
U.S. dollars, in increments of 1,000 units of such Specified Currency (provided
that any remaining principal amount hereof shall not be less than the minimum
authorized denomination hereof) at the option of the holder hereof at a price
equal to 100% of the principal amount to be repaid, together with interest
accrued and unpaid hereon to the date of repayment, provided that

                                      27
<PAGE>

if this Note is issued with original issue discount, this Note will be
repayable on the applicable Optional Repayment Date or Dates at the price(s)
specified on the face hereof. For this Note to be repaid at the option of the
holder hereof, the Paying Agent must receive at its corporate trust office in
the Borough of Manhattan, The City of New York, at least 15 but not more than
30 calendar days prior to the date of repayment, (i) this Note with the form
entitled "Option to Elect Repayment" below duly completed or (ii) a telegram,
telex, facsimile transmission or a letter from a member of a national
securities exchange or the National Association of Securities Dealers, Inc. or
a commercial bank or a trust company in the United States setting forth the
name of the holder of this Note, the principal amount hereof, the certificate
number of this Note or a description of this Note's tenor and terms, the
principal amount hereof to be repaid, a statement that the option to elect
repayment is being exercised thereby and a guarantee that this Note, together
with the form entitled "Option to Elect Repayment" duly completed, will be
received by the Paying Agent not later than the fifth Business Day after the
date of such telegram, telex, facsimile transmission or letter; provided, that
such telegram, telex, facsimile transmission or letter shall only be effective
if this Note and form duly completed are received by the Paying Agent by such
fifth Business Day. Exercise of such repayment option by the holder hereof
shall be irrevocable. In the event of repayment of this Note in part only, a
new Note or Notes for the amount of the unpaid portion hereof shall be issued
in the name of the holder hereof upon the cancellation hereof.

     Interest payments on this Note will include interest accrued to but
excluding the Interest Payment Dates or the Maturity Date (or any earlier
redemption or repayment date), as the case may be. Unless otherwise provided on
the face hereof, interest payments for this Note will be computed and paid on
the basis of a 360-day year of twelve 30-day months.

     In the case where the Interest Payment Date or the Maturity Date (or any
redemption or repayment date) does not fall on a Business Day, payment of
interest, premium, if any, or principal otherwise payable on such date need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the Interest Payment Date or on the
Maturity Date (or any redemption or repayment date), and no interest on such
payment shall accrue for the period from and after the Interest Payment Date or
the Maturity Date (or any redemption or repayment date) to such next succeeding
Business Day.

     This Note and all the obligations of the Issuer hereunder are direct,
unsecured obligations of the Issuer and rank without preference or priority
among themselves and pari passu with all other existing and future unsecured

exceptions in the event of liquidation upon insolvency.

is issuable only in fully registered form, without coupons, and, if denominated
in U.S. dollars, unless otherwise stated above, is issuable only in
denominations of U.S. $1,000 and any integral multiple of U.S. $1,000 in excess
thereof. If this Note is denominated in a Specified Currency other than U.S.
dollars, then, unless a higher minimum denomination is required by applicable
law, it is issuable only in denominations of the equivalent of U.S. $1,000
(rounded to an integral multiple of 1,000 units of such Specified Currency), or
any amount in excess thereof which is an integral multiple of 1,000 units of
such Specified Currency, as determined by reference to the noon dollar buying
rate in The City of New York for cable transfers of such Specified Currency

aforesaid office of the Trustee by surrendering this Note for cancellation,

Issuer and the Trustee and duly executed by the registered holder hereof in

Trustee will not be required (i) to register the transfer of or exchange any
Note that has been called for redemption in whole or in part, except the
unredeemed portion of Notes being redeemed in part, (ii) to register the
transfer of or exchange any Note if the holder thereof has exercised his right,

register the transfer of or exchange Notes to the extent and during the period
so provided in the Senior Indenture with respect to the redemption of Notes.
Notes are exchangeable at said office for other Notes of other authorized
denominations of equal aggregate principal amount having identical terms and
provisions. All such exchanges and transfers of Notes will be free of charge,
but the Issuer may require payment of a sum sufficient to cover any tax or
other governmental charge in connection therewith. All Notes surrendered for
exchange shall be accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Trustee and executed by the registered
holder in person or by the holder's attorney duly authorized in writing. The
date of registration of any Note delivered upon any exchange or transfer of
Notes shall be such that no gain or loss of interest results from such exchange
or transfer.

     In case this Note shall at any time become mutilated, defaced or be
destroyed, lost or stolen and this Note or evidence of the loss, theft or
destruction thereof (together with the indemnity hereinafter referred to and
such other documents or proof as may be required in the premises) shall be
delivered to the Trustee, the Issuer in its discretion may execute a new Note
of like tenor in exchange for this Note, but, if this Note is destroyed, lost
or stolen, only upon receipt of evidence satisfactory to the Trustee and the
Issuer that this Note was destroyed or lost or stolen and, if required, upon
receipt also of indemnity satisfactory to each of them. All expenses and
reasonable charges associated with procuring such indemnity and with the
preparation, authentication and delivery of a new Note shall be borne by the
owner of the Note mutilated, defaced, destroyed, lost or stolen.

     The Senior Indenture provides that (a) if an Event of Default (as defined
in the Senior Indenture) due to the default in payment of principal of,
premium, if any, or interest on, any series of debt securities issued under the
Senior Indenture, including the series of Senior Medium-Term Notes of which
this Note forms a part, or due to the default in the performance or breach of
any other covenant or warranty of the Issuer applicable to the debt securities
of such series but not applicable to all outstanding debt securities issued
under the Senior Indenture shall have occurred and be continuing, either the
Trustee or the holders of not less than 25% in

                                      29
<PAGE>

aggregate principal amount of the outstanding debt securities of each affected
series, voting as one class, by notice in writing to the Issuer and to the
Trustee, if given by the securityholders, may then declare the principal of all
debt securities of all such series and interest accrued thereon to be due and
payable immediately and (b) if an Event of Default due to a default in the
performance of any other of the covenants or agreements in the Senior Indenture
applicable to all outstanding debt securities issued thereunder, including this
Note, or due to certain events of bankruptcy, insolvency or reorganization of
the Issuer, shall have occurred and be continuing, either the Trustee or the
holders of not less than 25% in aggregate principal amount of all outstanding
debt securities issued under the Senior Indenture, voting as one class, by
notice in writing to the Issuer and to the Trustee, if given by the
securityholders, may declare the principal of all such debt securities and
interest accrued thereon to be due and payable immediately, but upon certain
conditions such declarations may be annulled and past defaults may be waived
(except a continuing default in payment of principal or premium, if any, or
interest on such debt securities) by the holders of a majority in aggregate
principal amount of the debt securities of all affected series then
outstanding.

     If the face hereof indicates that this Note is subject to "Modified
Payment upon Acceleration or Redemption," then (i) if the principal hereof is
declared to be due and payable as described in the preceding paragraph, the
amount of principal due and payable with respect to this Note shall be limited
to the aggregate principal amount hereof multiplied by the sum of the Issue
Price specified on the face hereof (expressed as a percentage of the aggregate
principal amount) plus the original issue discount amortized from the Interest
Accrual Date to the date of declaration, which amortization shall be calculated
using the "interest method" (computed in accordance with generally accepted
accounting principles in effect on the date of declaration), (ii) for the
purpose of any vote of securityholders taken pursuant to the Senior Indenture
prior to the acceleration of payment of this Note, the principal amount hereof
shall equal the amount that would be due and payable hereon, calculated as set
forth in clause (i) above, if this Note were declared to be due and payable on
the date of any such vote and (iii) for the purpose of any vote of
securityholders taken pursuant to the Senior Indenture following the
acceleration of payment of this Note, the principal amount hereof shall equal
the amount of principal due and payable with respect to this Note, calculated
as set forth in clause (i) above.

     If the face hereof indicates that this Note is subject to "Tax Redemption
and Payment of Additional Amounts," this Note may be redeemed, as a whole, at
the option of the Issuer at any time prior to maturity, upon the giving of a
notice of redemption as described below, at a redemption price equal to 100% of
the principal amount hereof, together with accrued interest to the date fixed
for redemption (except that if this Note is subject to "Modified Payment upon
Acceleration or Redemption," such redemption price would be limited to the
aggregate principal amount hereof multiplied by the sum of the Issue Price
specified on the face hereof (expressed as a percentage of the aggregate
principal amount) plus the original issue discount amortized from the Interest
Accrual Date to the date of redemption, which amortization shall be calculated
using the "interest method" (computed in accordance with generally accepted
accounting principles in effect on the date of redemption) (the "Amortized
Amount")), if the Issuer determines that, as a result of any change in or
amendment to the laws, or any regulations or rulings promulgated thereunder, of
the United States or of any political subdivision or taxing authority thereof
or therein affecting taxation, or any change in official position regarding the
application or

                                      30
<PAGE>

interpretation of such laws, regulations or rulings, which change or amendment
becomes effective on or after the Initial Offering Date hereof, the Issuer has
or will become obligated to pay Additional Amounts, as defined below, with
respect to this Note as described below. Prior to the giving of any notice of
redemption pursuant to this paragraph, the Issuer shall deliver to the Trustee
(i) a certificate stating that the Issuer is entitled to effect such redemption
and setting forth a statement of facts showing that the conditions precedent to
the right of the Issuer to so redeem have occurred, and (ii) an opinion of
independent legal counsel satisfactory to the Trustee to such effect based on
such statement of facts; provided that no such notice of redemption shall be
given earlier than 60 calendar days prior to the earliest date on which the
Issuer would be obligated to pay such Additional Amounts if a payment in
respect of this Note were then due.

     Notice of redemption will be given not less than 30 nor more than 60
calendar days prior to the date fixed for redemption or within the Redemption
Notice Period specified on the face hereof, which date and the applicable
redemption price will be specified in the notice.

     If the face hereof indicates that this Note is subject to "Tax Redemption
and Payment of Additional Amounts," the Issuer will, subject to certain
exceptions and limitations set forth below, pay such additional amounts (the
"Additional Amounts") to the holder of this Note who is a United States Alien
as may be necessary in order that every net payment of the principal of and
interest on this Note and any other amounts payable on this Note, after
withholding or deduction for or on account of any present or future tax,
assessment or governmental charge imposed upon or as a result of such payment
by the United States, or any political subdivision or taxing authority thereof
or therein, will not be less than the amount provided for in this Note to be
then due and payable. The Issuer will not, however, make any payment of
Additional Amounts to any such holder who is a United States Alien for or on
account of:

          (a) any present or future tax, assessment or other governmental
     charge that would not have been so imposed but for (i) the existence of
     any present or former connection between such holder, or between a
     fiduciary, settlor, beneficiary, member or shareholder of such holder, if
     such holder is an estate, a trust, a partnership or a corporation for
     United States federal income tax purposes, and the United States,
     including, without limitation, such holder, or such fiduciary, settlor,
     beneficiary, member or shareholder, being or having been a citizen or
     resident thereof or being or having been engaged in a trade or business or
     present therein or having, or having had, a permanent establishment
     therein or (ii) the presentation by or on behalf of the holder of this
     Note for payment on a date more than 15 calendar days after the date on
     which such payment became due and payable or the date on which payment
     thereof is duly provided for, whichever occurs later;

          (b) any estate, inheritance, gift, sales, transfer, excise or
     personal property tax or any similar tax, assessment or governmental
     charge;

          (c) any tax, assessment or other governmental charge imposed by
     reason of such holder's past or present status as a personal holding
     company or foreign personal holding company or controlled foreign
     corporation or passive foreign investment company with respect to the
     United States or as a corporation which accumulates earnings to avoid
     United States federal income tax or as a private foundation or other
     tax-exempt organization or a

                                      31
<PAGE>

     bank receiving interest under Section 881(c)(3)(A) of the Internal Revenue
     Code of 1986, as amended;

          (d) any tax, assessment or other governmental charge that is payable
     otherwise than by withholding or deduction from payments on or in respect
     of this Note;

          (e) any tax, assessment or other governmental charge required to be
     withheld by any Paying Agent from any payment of principal of, or interest
     on, this Note, if such payment can be made without such withholding by any
     other Paying Agent in a city in Western Europe;

          (f) any tax, assessment or other governmental charge that would not
     have been imposed but for the failure to comply with certification,
     information or other reporting requirements concerning the nationality,
     residence or identity of the holder or beneficial owner of this Note, if
     such compliance is required by statute or by regulation of the United
     States or of any political subdivision or taxing authority thereof or
     therein as a precondition to relief or exemption from such tax, assessment
     or other governmental charge;

          (g) any tax, assessment or other governmental charge imposed by
     reason of such holder's past or present status as the actual or
     constructive owner of 10% or more of the total combined voting power of
     all classes of stock entitled to vote of the Issuer or as a direct or
     indirect subsidiary of the Issuer; or

          (h) any combination of items (a), (b), (c), (d), (e), (f) or (g).

In addition, the Issuer shall not be required to make any payment of Additional
Amounts (i) to any such holder where such withholding or deduction is imposed
on a payment to an individual and is required to be made pursuant to any law
implementing or complying with, or introduced in order to conform to, any
European Union Directive on the taxation of savings; or (ii) by or on behalf of
a holder who would have been able to avoid such withholding or deduction by
presenting this Note or the relevant coupon to another Paying Agent in a member
state of the European Union. Nor shall the Issuer pay Additional Amounts with
respect to any payment on this Note to a United States Alien who is a fiduciary
or partnership or other than the sole beneficial owner of such payment to the
extent such payment would be required by the laws of the United States (or any
political subdivision thereof) to be included in the income, for tax purposes,
of a beneficiary or settlor with respect to such fiduciary or a member of such
partnership or a beneficial owner who would not have been entitled to the
Additional Amounts had such beneficiary, settlor, member or beneficial owner
been the holder of this Note.

     The Senior Indenture permits the Issuer and the Trustee, with the consent
of the holders of not less than a majority in aggregate principal amount of the
debt securities of all series issued under the Senior Indenture then
outstanding and affected (voting as one class), to execute supplemental
indentures adding any provisions to or changing in any manner the rights of the
holders of each series so affected; provided that the Issuer and the Trustee
may not, without the consent of the holder of each outstanding debt security
affected thereby, (a) extend the final maturity of any such debt security, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable on redemption
thereof, or change the currency of payment thereof, or modify or amend the
provisions for

                                      32
<PAGE>

conversion of any currency into any other currency, or modify or amend the
provisions for conversion or exchange of the debt security for securities of
the Issuer or other entities or for other property or the cash value of the
property (other than as provided in the antidilution provisions or other
similar adjustment provisions of the debt securities or otherwise in accordance
with the terms thereof), or impair or affect the rights of any holder to
institute suit for the payment thereof or (b) reduce the aforesaid percentage
in principal amount of debt securities the consent of the holders of which is
required for any such supplemental indenture.

     Except as set forth below, if the principal of, premium, if any, or
interest on this Note is payable in a Specified Currency other than U.S.
dollars and such Specified Currency is not available to the Issuer for making
payments hereon due to the imposition of exchange controls or other
circumstances beyond the control of the Issuer or is no longer used by the
government of the country issuing such currency or for the settlement of
transactions by public institutions within the international banking community,
then the Issuer will be entitled to satisfy its obligations to the holder of
this Note by making such payments in U.S. dollars on the basis of the Market
Exchange Rate on the date of such payment or, if the Market Exchange Rate is
not available on such date, as of the most recent practicable date; provided,
however, that if the euro has been substituted for such Specified Currency, the
Issuer may at its option (or shall, if so required by applicable law) without
the consent of the holder of this Note effect the payment of principal of,
premium, if any, or interest on any Note denominated in such Specified Currency
in euro in lieu of such Specified Currency in conformity with legally
applicable measures taken pursuant to, or by virtue of, the Treaty establishing
the European Community, as amended. Any payment made under such circumstances
in U.S. dollars or euro where the required payment is in an unavailable
Specified Currency will not constitute an Event of Default. If such Market
Exchange Rate is not then available to the Issuer or is not published for a
particular Specified Currency, the Market Exchange Rate will be based on the
highest bid quotation in The City of New York received by the Exchange Rate
Agent at approximately 11:00 a.m., New York City time, on the second Business
Day preceding the date of such payment from three recognized foreign exchange
dealers (the "Exchange Dealers") for the purchase by the quoting Exchange
Dealer of the Specified Currency for U.S. dollars for settlement on the payment
date, in the aggregate amount of the Specified Currency payable to those
holders or beneficial owners of Notes and at which the applicable Exchange
Dealer commits to execute a contract. One of the Exchange Dealers providing
quotations may be the Exchange Rate Agent unless the Exchange Rate Agent is an
affiliate of the Issuer. If those bid quotations are not available, the
Exchange Rate Agent shall determine the market exchange rate at its sole
discretion.

     The "Exchange Rate Agent" shall be Morgan Stanley & Co. Incorporated,
unless otherwise indicated on the face hereof.

     All determinations referred to above made by, or on behalf of, the Issuer
or by, or on behalf of, the Exchange Rate Agent shall be at such entity's sole
discretion and shall, in the absence of manifest error, be conclusive for all
purposes and binding on holders of Notes and coupons.

     So long as this Note shall be outstanding, the Issuer will cause to be
maintained an office or agency for the payment of the principal of and premium,
if any, and interest on this Note as herein provided in the Borough of
Manhattan, The City of New York, and an office or agency in

                                      33
<PAGE>

said Borough of Manhattan for the registration, transfer and exchange as
aforesaid of the Notes. The Issuer may designate other agencies for the payment
of said principal, premium and interest at such place or places (subject to
applicable laws and regulations) as the Issuer may decide. So long as there
shall be such an agency, the Issuer shall keep the Trustee advised of the names
and locations of such agencies, if any are so designated. If any European Union
Directive on the taxation of savings comes into force, the Issuer will, to the
extent possible as a matter of law, maintain a Paying Agent in a member state
of the European Union that will not be obligated to withhold or deduct tax
pursuant to any such Directive or any law implementing or complying with, or
introduced in order to conform to, such Directive.

     With respect to moneys paid by the Issuer and held by the Trustee or any
Paying Agent for payment of the principal of or interest or premium, if any, on
any Notes that remain unclaimed at the end of two years after such principal,
interest or premium shall have become due and payable (whether at maturity or
upon call for redemption or otherwise), (i) the Trustee or such Paying Agent
shall notify the holders of such Notes that such moneys shall be repaid to the
Issuer and any person claiming such moneys shall thereafter look only to the
Issuer for payment thereof and (ii) such moneys shall be so repaid to the
Issuer. Upon such repayment all liability of the Trustee or such Paying Agent
with respect to such moneys shall thereupon cease, without, however, limiting
in any way any obligation that the Issuer may have to pay the principal of or
interest or premium, if any, on this Note as the same shall become due.

     No provision of this Note or of the Senior Indenture shall alter or impair
the obligation of the Issuer, which is absolute and unconditional, to pay the
principal of, premium, if any, and interest on this Note at the time, place,
and rate, and in the coin or currency, herein prescribed unless otherwise
agreed between the Issuer and the registered holder of this Note.

     Prior to due presentment of this Note for registration of transfer, the
Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
holder in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and none of the Issuer, the
Trustee or any such agent shall be affected by notice to the contrary.

     No recourse shall be had for the payment of the principal of, premium, if
any, or the interest on this Note, for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Senior Indenture or any
indenture supplemental thereto, against any incorporator, shareholder, officer
or director, as such, past, present or future, of the Issuer or of any
successor corporation, either directly or through the Issuer or any successor
corporation, whether by virtue of any constitution, statute or rule of law or
by the enforcement of any assessment or penalty or otherwise, all such
liability being, by the acceptance hereof and as part of the consideration for
the issue hereof, expressly waived and released.

     This Note shall for all purposes be governed by, and construed in
accordance with, the laws of the State of New York.

     As used herein, the term "United States Alien" means any person who is,
for United States federal income tax purposes, (i) a nonresident alien
individual, (ii) a foreign corporation, (iii) a nonresident alien fiduciary of
a foreign estate or trust or (iv) a foreign partnership one or

                                      34

not otherwise defined herein shall have the meanings assigned to them in the
Senior Indenture.

                         or not the holder of this SPARQS receives the notice.
                         Notice of the date to which the Maturity Date has been
                         rescheduled as a result of postponement of the Final

Record Date............. Notwithstanding the definition of "Record Date" on page
                         23 hereof, the Record Date for each Interest Payment
                         Date, including the Interest Payment Date scheduled to
                         occur on the Maturity Date, shall be the date 5
                         calendar days prior to such scheduled Interest Payment
                         Date, whether or not that date is a Business Day;
                         provided, however, that in the event that the Issuer
                         exercises the Morgan Stanley Call Right, no Interest
                         Payment Date shall occur after the Morgan Stanley
                         Notice Date, except for any Interest Payment Date for
                         which the Morgan Stanley Notice Date falls on or after
                         the "ex-interest" date for the related interest
                         payment, in which case the related interest payment
                         shall be made on such Interest Payment Date; and
                         provided, further, that accrued but unpaid interest
                         payable on the Call Date, if any, shall be payable to
                         the person to whom the Call Price is payable. The
                         "ex-interest" date for any interest payment is the date
                         on which purchase transactions in the SPARQS no longer
                         carry the right to receive such interest payment.

                         In the event that the Issuer exercises the Morgan
                         Stanley Call Right and the Morgan Stanley Notice Date
                         falls before the "ex-interest" date for an interest
                         payment, so that as a result a scheduled Interest
                         Payment Date will not occur, the Issuer shall cause the
                         Calculation Agent to give notice to the Trustee and to
                         the Depositary, in each case in the manner and at the
                         time described in the second and third paragraphs under
                         "Morgan Stanley Call Right" below, that no Interest
                         Payment Date will occur after such Morgan Stanley
                         Notice Date.

                         of payment of such Call Price, (vi) that such delivery
                         will be made upon presentation and surrender of this
                         SPARQS, (vii) that such exchange is pursuant to the
                         Morgan Stanley Call Right and (viii) if applicable, the
                         date to which the Maturity Date has been extended due

                         Trading Day (the "date of acceleration"). Upon such
                         acceleration, the holder of each $    principal amount
                         of this SPARQS shall receive per SPARQS on the date of
                         acceleration:

                             (i) a number of shares of XM Satellite Stock at the
                             then current Exchange Ratio;

                             (ii)accrued but unpaid interest on each $ principal
                             amount of this SPARQS to but excluding the date of
                             acceleration; and

                             (iii) an amount of cash as determined by the
                             Calculation Agent equal to the sum of the present
                             values of the remaining scheduled payments of
                             interest on each $      principal amount of this
                             SPARQS (excluding the amounts included in clause
                             (ii) above) discounted to the date of acceleration.
                             The present value of each remaining scheduled
                             payment will be based on the comparable yield that
                             the Issuer would pay on a non-interest bearing,
                             senior unsecured debt obligation of the Issuer
                             having a maturity equal to the term of each such
                             remaining scheduled payment, as determined by the
                             Calculation Agent.

                         maturity, the Issuer shall deliver the aggregate number
                         of shares of XM Satellite Stock due with respect to
                         this SPARQS, as described above, but the Issuer shall
                         pay cash in lieu of delivering any fractional share of
                         XM Satellite Stock in an amount equal to the
                         corresponding fractional Closing Price of such fraction
                         of a share of XM Satellite Stock as determined by the

                         resulting from such calculations shall be rounded to

                         reverse stock split, then once such split has become
                         effective, the Exchange Ratio shall be adjusted to
                         equal the product of the prior Exchange Ratio and the
                         number of shares issued in such stock split or reverse
                         stock split with respect to one share of XM Satellite

                         Satellite Stock as a result of the triggering of any

                         Ratio with respect to XM Satellite Stock shall be
                         adjusted on the ex-dividend date so that the new
                         Exchange Ratio shall equal the product of (i) the prior
                         Exchange Ratio and (ii) a fraction, the numerator of
                         which is the Base Closing Price, and the denominator of

                         exceeds the Extraordinary Dividend. If any
                         Extraordinary Dividend is at least 35% of the Base
                         Closing Price, then, instead of adjusting the Exchange
                         Ratio, the amount payable upon exchange at maturity
                         shall be determined as described in paragraph 5 below,
                         and the Extraordinary Dividend shall be allocated to

                         non-cash component of an Extraordinary Dividend shall
                         be determined on the ex-dividend date for such
                         distribution by the Calculation Agent, whose
                         determination shall be conclusive in the absence of
                         manifest error. A distribution on XM Satellite Stock
                         described in clause (i), (iv) or (v) of the first
                         sentence of paragraph 5 below shall cause an adjustment
                         to the Exchange Ratio pursuant only to clause (i), (iv)
                         or (v) of the first sentence of paragraph 5, as

                         written notice to the Trustee at its New York office,
                         on which notice the Trustee may conclusively rely, and

                         and of the three Reference Basket Stocks selected as
                         promptly as possible and in no event later than five

                         Exchange Ratio) shall be required unless such
                         adjustment would require a change of at least 0.1% in
                         the Exchange Ratio then in effect. The Exchange Ratio
                         resulting from any of the adjustments specified above
                         will be rounded to the nearest one hundred-thousandth,
                         with five one-millionths rounded upward. Adjustments to
                         the Exchange Ratios will be made up to the close of
                         business on the third Trading Day prior to the

                         calculating the Exchange Ratio shall be made other than
                         those specified above.

                         determinations and calculations with respect to any
                         distributions of stock, other securities or other
                         property or assets (including cash) in connection with
                         any corporate event described in paragraphs 1 through 5
                         above, and its determinations and calculations with
                         respect thereto shall be conclusive in the absence of
                         manifest error.

                         The Calculation Agent shall provide information as to
                         any adjustments to the Exchange Ratio, or to the method
                         of calculating the amount payable upon exchange at
                         maturity of the SPARQS made pursuant to paragraph 5
                         above, upon written request by the holder of this

                         (2) a decision to permanently discontinue trading in

                         to the contrary) to characterize each $       principal
                         amount of this SPARQS for all tax purposes as a unit
                         consisting of (A) a terminable contract (the
                         "Terminable Forward Contract") that (i) requires the
                         holder of this SPARQS (subject to the Morgan Stanley
                         Call Right) to purchase, and the Issuer to sell, for an
                         amount equal to $        (the "Forward Price"), XM
                         Satellite Stock at maturity and (ii) allows the Issuer,
                         upon exercise of the Morgan Stanley Call Right, to
                         terminate the Terminable Forward Contract by returning
                         to such holder the Deposit (as defined below) and
                         paying to such holder an amount of cash equal to the
                         difference between the Deposit and the Call Price and
                         (B) a deposit with the Issuer of a fixed amount of
                         cash, equal to the Issue Price per each $
                         principal amount of this SPARQS, to secure the holder's
                         obligation to purchase XM Satellite Stock pursuant to
                         the Terminable Forward Contract (the "Deposit"), which
                         Deposit bears a quarterly compounded yield of   % per

     Morgan Stanley, a Delaware corporation (together with its successors and
assigns, the "Issuer"), for value received, hereby promises to pay to CEDE &
CO., or registered assignees, the amount of XM Satellite Stock (or other
Exchange Property), as determined in accordance with the provisions set forth
under "Exchange at Maturity" above, due with respect to the principal sum of
U.S. $           (UNITED STATES DOLLARS                 ) on the Maturity Date
specified above (except to the extent redeemed or repaid prior to maturity) and
to pay interest thereon at the Interest Rate per annum specified above, from and
including the Interest Accrual Date specified above until the principal hereof
is paid or duly made available for payment weekly, monthly, quarterly,
semiannually or annually in arrears as specified above as the Interest Payment
Period on each Interest Payment Date (as specified above), 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 between a Record Date, as defined
below, and the next succeeding Interest Payment Date, interest payments will
commence on the second Interest Payment Date succeeding the Interest Accrual
Date to the registered holder of this Note on the Record Date with respect to
such second Interest Payment Date; and provided, further, that if this Note is
subject to "Annual Interest Payments," interest payments shall be made annually
in arrears and the term "Interest Payment Date" shall be deemed to mean the
first day of March in each year.

     Interest on this Note will accrue from and including the most recent 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 principal hereof has been paid or duly made
available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, subject to certain exceptions
described herein, be paid to the person in whose name this Note (or one or more
predecessor Notes) is registered at the close of business on the date 15
calendar days prior to such Interest Payment Date (whether or not a Business Day
(as defined below)) (each such date, a "Record Date"); provided, however, that
interest payable at maturity (or any redemption or repayment date) will be
payable to the person to whom the principal hereof shall be payable. As used
herein, "Business Day" means any day, other than a Saturday or Sunday, (a) that
is neither a legal holiday nor a day on which banking institutions are
authorized or required by law or regulation to close (x) in The City of New York
or (y) if this Note is denominated in a Specified Currency other than U.S.
dollars, euro or Australian dollars, in the principal financial center of the
country of the Specified Currency, or (z) if this Note is denominated in
Australian dollars, in Sydney and (b) if this Note is denominated in euro, that
is also a day on which the Trans-European Automated Real-time Gross Settlement
Express Transfer System ("TARGET") is operating (a "TARGET Settlement Day").

     Payment of the principal of this Note, any premium and the interest due at
maturity (or any redemption or repayment date), unless this Note is denominated
in a Specified Currency other than U.S. dollars and is to be paid in whole or in
part in such Specified Currency, will be made in immediately available funds
upon surrender of this Note at the office or agency of the Paying Agent, as
defined on the reverse hereof, maintained for that purpose in the Borough of
Manhattan, The City of New York, or at such other paying agency as the Issuer
may determine, in U.S. dollars. U.S. dollar payments of interest, other than
interest due at maturity or on any date of redemption or repayment, will be made
by U.S. dollar check mailed to the address of the

                                       23
<PAGE>

person entitled thereto as such address shall appear in the Note register. A
holder of U.S. $10,000,000 (or the equivalent in a Specified Currency) or more
in aggregate principal amount of Notes having the same Interest Payment Date,
the interest on which is payable in U.S. dollars, shall be entitled to receive
payments of interest, other than interest due at maturity or on any date of
redemption or repayment, by wire transfer of immediately available funds if
appropriate wire transfer instructions have been received by the Paying Agent in
writing not less than 15 calendar days prior to the applicable Interest Payment
Date.

     If this Note is denominated in a Specified Currency other than U.S.
dollars, and the holder does not elect (in whole or in part) to receive payment
in U.S. dollars pursuant to the next succeeding paragraph, payments of interest,
principal or any premium with regard to this Note will be made by wire transfer
of immediately available funds to an account maintained by the holder hereof
with a bank located outside the United States if appropriate wire transfer
instructions have been received by the Paying Agent in writing, with respect to
payments of interest, on or prior to the fifth Business Day after the applicable
Record Date and, with respect to payments of principal or any premium, at least
ten Business Days prior to the Maturity Date or any redemption or repayment
date, as the case may be; provided that, if payment of interest, principal or
any premium with regard to this Note is payable in euro, the account must be a
euro account in a country for which the euro is the lawful currency, provided,
further, that if such wire transfer instructions are not received, such payments
will be made by check payable in such Specified Currency mailed to the address
of the person entitled thereto as such address shall appear in the Note
register; and provided, further, that payment of the principal of this Note, any
premium and the interest due at maturity (or on any redemption or repayment
date) will be made upon surrender of this Note at the office or agency referred
to in the preceding paragraph.

     If so indicated on the face hereof, the holder of this Note, if denominated
in a Specified Currency other than U.S. dollars, may elect to receive all or a
portion of payments on this Note in U.S. dollars by transmitting a written
request to the Paying Agent, on or prior to the fifth Business Day after such
Record Date or at least ten Business Days prior to the Maturity Date or any
redemption or repayment date, as the case may be. Such election shall remain in
effect unless such request is revoked by written notice to the Paying Agent as
to all or a portion of payments on this Note at least five Business Days prior
to such Record Date, for payments of interest, or at least ten calendar days
prior to the Maturity Date or any redemption or repayment date, for payments of
principal, as the case may be.

     If the holder elects to receive all or a portion of payments of principal
of, premium, if any, and interest on this Note, if denominated in a Specified
Currency other than U.S. dollars, in U.S. dollars, the Exchange Rate Agent (as
defined on the reverse hereof) will convert such payments into U.S. dollars. In
the event of such an election, payment in respect of this Note will be based
upon the exchange rate as determined by the Exchange Rate Agent based on the
highest bid quotation in The City of New York received by such Exchange Rate
Agent at approximately 11:00 a.m., New York City time, on the second Business
Day preceding the applicable payment date from three recognized foreign exchange
dealers (one of which may be the Exchange Rate Agent unless such Exchange Rate
Agent is an affiliate of the Issuer) for the purchase by the quoting dealer of
the Specified Currency for U.S. dollars for settlement on such payment date in
the amount of the Specified Currency payable in the absence of such an election
to such holder

                                       24
<PAGE>

and at which the applicable dealer commits to execute a contract. If such bid
quotations are not available, such payment will be made in the Specified
Currency. All currency exchange costs will be borne by the holder of this Note
by deductions from such payments.

     Reference is hereby made to the further provisions of this Note set forth
on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof 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.

     IN WITNESS WHEREOF, the Issuer has caused this Note to be duly executed.

                          FORM OF REVERSE OF SECURITY

     This Note is one of a duly authorized issue of Senior Global Medium-Term
Notes, Series F, having maturities more than nine months from the date of issue
(the "Notes") of the Issuer. The Notes are issuable under a Senior Indenture,
dated as of November 1, 2004, between the Issuer and JPMorgan Chase Bank, N.A.
(formerly known as JPMorgan Chase 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, N.A. at its corporate trust office in The City of New York
as the paying agent (the "Paying Agent," which term includes any additional or
successor Paying Agent appointed by the Issuer) with respect to the Notes. The
terms of individual Notes may vary with respect to interest rates, interest rate
formulas, issue dates, maturity dates, or otherwise, all as provided in the
Senior Indenture. To the extent not inconsistent herewith, the terms of the
Senior Indenture are hereby incorporated by reference herein.

     Unless otherwise indicated on the face hereof, this Note will not be
subject to any sinking fund and, unless otherwise provided on the face hereof in
accordance with the provisions of the following two paragraphs, will not be
redeemable or subject to repayment at the option of the holder prior to
maturity.

     If so indicated on the face hereof, this Note may be redeemed in whole or
in part at the option of the Issuer on or after the Initial Redemption Date
specified on the face hereof on the terms set forth on the face hereof, together
with interest accrued and unpaid hereon to the date of redemption. If this Note
is subject to "Annual Redemption Percentage Reduction," the Initial Redemption
Percentage indicated on the face hereof will be reduced on each anniversary of
the Initial Redemption Date by the Annual Redemption Percentage Reduction
specified on the face hereof until the redemption price of this Note is 100% of
the principal amount hereof, together with interest accrued and unpaid hereon to
the date of redemption. Notice of redemption shall be mailed to the registered
holders of the Notes designated for redemption at their addresses as the same
shall appear on the Note register not less than 30 nor more than 60 calendar
days prior to the date fixed for redemption or within the Redemption Notice
Period specified on the face hereof, subject to all the conditions and
provisions of the Senior Indenture. In the event of redemption of this Note in
part only, a new Note or Notes for the amount of the unredeemed portion hereof
shall be issued in the name of the holder hereof upon the cancellation hereof.

     If so indicated on the face of this Note, this Note will be subject to
repayment at the option of the holder on the Optional Repayment Date or Dates
specified on the face hereof on the terms set forth herein. On any Optional
Repayment Date, this Note will be repayable in whole or in part in increments of
$1,000 or, if this Note is denominated in a Specified Currency other than U.S.
dollars, in increments of 1,000 units of such Specified Currency (provided that
any remaining principal amount hereof shall not be less than the minimum
authorized denomination hereof) at the option of the holder hereof at a price
equal to 100% of the principal amount to be repaid, together with interest
accrued and unpaid hereon to the date of repayment, provided that

                                       27
<PAGE>

if this Note is issued with original issue discount, this Note will be repayable
on the applicable Optional Repayment Date or Dates at the price(s) specified on
the face hereof. For this Note to be repaid at the option of the holder hereof,
the Paying Agent must receive at its corporate trust office in the Borough of
Manhattan, The City of New York, at least 15 but not more than 30 calendar days
prior to the date of repayment, (i) this Note with the form entitled "Option to
Elect Repayment" below duly completed or (ii) a telegram, telex, facsimile
transmission or a letter from a member of a national securities exchange or the
National Association of Securities Dealers, Inc. or a commercial bank or a trust
company in the United States setting forth the name of the holder of this Note,
the principal amount hereof, the certificate number of this Note or a
description of this Note's tenor and terms, the principal amount hereof to be
repaid, a statement that the option to elect repayment is being exercised
thereby and a guarantee that this Note, together with the form entitled "Option
to Elect Repayment" duly completed, will be received by the Paying Agent not
later than the fifth Business Day after the date of such telegram, telex,
facsimile transmission or letter; provided, that such telegram, telex, facsimile
transmission or letter shall only be effective if this Note and form duly
completed are received by the Paying Agent by such fifth Business Day. Exercise
of such repayment option by the holder hereof shall be irrevocable. In the event
of repayment of this Note in part only, a new Note or Notes for the amount of
the unpaid portion hereof shall be issued in the name of the holder hereof upon
the cancellation hereof.

     Interest payments on this Note will include interest accrued to but
excluding the Interest Payment Dates or the Maturity Date (or any earlier
redemption or repayment date), as the case may be. Unless otherwise provided on
the face hereof, interest payments for this Note will be computed and paid on
the basis of a 360-day year of twelve 30-day months.

     In the case where the Interest Payment Date or the Maturity Date (or any
redemption or repayment date) does not fall on a Business Day, payment of
interest, premium, if any, or principal otherwise payable on such date need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the Interest Payment Date or on the
Maturity Date (or any redemption or repayment date), and no interest on such
payment shall accrue for the period from and after the Interest Payment Date or
the Maturity Date (or any redemption or repayment date) to such next succeeding
Business Day.

     This Note and all the obligations of the Issuer hereunder are direct,
unsecured obligations of the Issuer and rank without preference or priority
among themselves and pari passu with all other existing and future unsecured and
unsubordinated indebtedness of the Issuer, subject to certain statutory
exceptions in the event of liquidation upon insolvency.

     This Note, and any Note or Notes issued upon transfer or exchange hereof,
is issuable only in fully registered form, without coupons, and, if denominated
in U.S. dollars, unless otherwise stated above, is issuable only in
denominations of U.S. $1,000 and any integral multiple of U.S. $1,000 in excess
thereof. If this Note is denominated in a Specified Currency other than U.S.
dollars, then, unless a higher minimum denomination is required by applicable
law, it is issuable only in denominations of the equivalent of U.S. $1,000
(rounded to an integral multiple of 1,000 units of such Specified Currency), or
any amount in excess thereof which is an integral multiple of 1,000 units of
such Specified Currency, as determined by reference to the noon dollar buying
rate in The City of New York for cable transfers of such Specified Currency

                                       28

published by the Federal Reserve Bank of New York (the "Market Exchange Rate")
on the Business Day immediately preceding the date of issuance.

     The Trustee has been appointed registrar for the Notes, and the Trustee
will maintain at its office in The City of New York a register for the
registration and transfer of Notes. This Note may be transferred at the
aforesaid office of the Trustee by surrendering this Note for cancellation,
accompanied by a written instrument of transfer in form satisfactory to the
Issuer and the Trustee and duly executed by the registered holder hereof in
person or by the holder's attorney duly authorized in writing, and thereupon the
Trustee shall issue in the name of the transferee or transferees, in exchange
herefor, a new Note or Notes having identical terms and provisions and having a
like aggregate principal amount in authorized denominations, subject to the
terms and conditions set forth herein; provided, however, that the Trustee will
not be required (i) to register the transfer of or exchange any Note that has
been called for redemption in whole or in part, except the unredeemed portion of
Notes being redeemed in part, (ii) to register the transfer of or exchange any
Note if the holder thereof has exercised his right, if any, to require the
Issuer to repurchase such Note in whole or in part, except the portion of such
Note not required to be repurchased, or (iii) to register the transfer of or
exchange Notes to the extent and during the period so provided in the Senior
Indenture with respect to the redemption of Notes. Notes are exchangeable at
said office for other Notes of other authorized denominations of equal aggregate
principal amount having identical terms and provisions. All such exchanges and
transfers of Notes will be free of charge, but the Issuer may require payment of
a sum sufficient to cover any tax or other governmental charge in connection
therewith. All Notes surrendered for exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Issuer and the Trustee and
executed by the registered holder in person or by the holder's attorney duly
authorized in writing. The date of registration of any Note delivered upon any
exchange or transfer of Notes shall be such that no gain or loss of interest
results from such exchange or transfer.

     In case this Note shall at any time become mutilated, defaced or be
destroyed, lost or stolen and this Note or evidence of the loss, theft or
destruction thereof (together with the indemnity hereinafter referred to and
such other documents or proof as may be required in the premises) shall be
delivered to the Trustee, the Issuer in its discretion may execute a new Note of
like tenor in exchange for this Note, but, if this Note is destroyed, lost or
stolen, only upon receipt of evidence satisfactory to the Trustee and the Issuer
that this Note was destroyed or lost or stolen and, if required, upon receipt
also of indemnity satisfactory to each of them. All expenses and reasonable
charges associated with procuring such indemnity and with the preparation,
authentication and delivery of a new Note shall be borne by the owner of the
Note mutilated, defaced, destroyed, lost or stolen.

     The Senior Indenture provides that (a) if an Event of Default (as defined
in the Senior Indenture) due to the default in payment of principal of, premium,
if any, or interest on, any series of debt securities issued under the Senior
Indenture, including the series of Senior Medium-Term Notes of which this Note
forms a part, or due to the default in the performance or breach of any other
covenant or warranty of the Issuer applicable to the debt securities of such
series but not applicable to all outstanding debt securities issued under the
Senior Indenture shall have occurred and be continuing, either the Trustee or
the holders of not less than 25% in

                                       29
<PAGE>

aggregate principal amount of the outstanding debt securities of each affected
series, voting as one class, by notice in writing to the Issuer and to the
Trustee, if given by the securityholders, may then declare the principal of all
debt securities of all such series and interest accrued thereon to be due and
payable immediately and (b) if an Event of Default due to a default in the
performance of any other of the covenants or agreements in the Senior Indenture
applicable to all outstanding debt securities issued thereunder, including this
Note, or due to certain events of bankruptcy, insolvency or reorganization of
the Issuer, shall have occurred and be continuing, either the Trustee or the
holders of not less than 25% in aggregate principal amount of all outstanding
debt securities issued under the Senior Indenture, voting as one class, by
notice in writing to the Issuer and to the Trustee, if given by the
securityholders, may declare the principal of all such debt securities and
interest accrued thereon to be due and payable immediately, but upon certain
conditions such declarations may be annulled and past defaults may be waived
(except a continuing default in payment of principal or premium, if any, or
interest on such debt securities) by the holders of a majority in aggregate
principal amount of the debt securities of all affected series then outstanding.

     If the face hereof indicates that this Note is subject to "Modified Payment
upon Acceleration or Redemption," then (i) if the principal hereof is declared
to be due and payable as described in the preceding paragraph, the amount of
principal due and payable with respect to this Note shall be limited to the
aggregate principal amount hereof multiplied by the sum of the Issue Price
specified on the face hereof (expressed as a percentage of the aggregate
principal amount) plus the original issue discount amortized from the Interest
Accrual Date to the date of declaration, which amortization shall be calculated
using the "interest method" (computed in accordance with generally accepted
accounting principles in effect on the date of declaration), (ii) for the
purpose of any vote of securityholders taken pursuant to the Senior Indenture
prior to the acceleration of payment of this Note, the principal amount hereof
shall equal the amount that would be due and payable hereon, calculated as set
forth in clause (i) above, if this Note were declared to be due and payable on
the date of any such vote and (iii) for the purpose of any vote of
securityholders taken pursuant to the Senior Indenture following the
acceleration of payment of this Note, the principal amount hereof shall equal
the amount of principal due and payable with respect to this Note, calculated as
set forth in clause (i) above.

     If the face hereof indicates that this Note is subject to "Tax Redemption
and Payment of Additional Amounts," this Note may be redeemed, as a whole, at
the option of the Issuer at any time prior to maturity, upon the giving of a
notice of redemption as described below, at a redemption price equal to 100% of
the principal amount hereof, together with accrued interest to the date fixed
for redemption (except that if this Note is subject to "Modified Payment upon
Acceleration or Redemption," such redemption price would be limited to the
aggregate principal amount hereof multiplied by the sum of the Issue Price
specified on the face hereof (expressed as a percentage of the aggregate
principal amount) plus the original issue discount amortized from the Interest
Accrual Date to the date of redemption, which amortization shall be calculated
using the "interest method" (computed in accordance with generally accepted
accounting principles in effect on the date of redemption) (the "Amortized
Amount")), if the Issuer determines that, as a result of any change in or
amendment to the laws, or any regulations or rulings promulgated thereunder, of
the United States or of any political subdivision or taxing authority thereof or
therein affecting taxation, or any change in official position regarding the
application or

                                       30
<PAGE>

interpretation of such laws, regulations or rulings, which change
or amendment becomes effective on or after the Initial Offering Date hereof, the
Issuer has or will become obligated to pay Additional Amounts, as defined below,
with respect to this Note as described below. Prior to the giving of any notice
of redemption pursuant to this paragraph, the Issuer shall deliver to the
Trustee (i) a certificate stating that the Issuer is entitled to effect such
redemption and setting forth a statement of facts showing that the conditions
precedent to the right of the Issuer to so redeem have occurred, and (ii) an
opinion of independent legal counsel satisfactory to the Trustee to such effect
based on such statement of facts; provided that no such notice of redemption
shall be given earlier than 60 calendar days prior to the earliest date on which
the Issuer would be obligated to pay such Additional Amounts if a payment in
respect of this Note were then due.

     Notice of redemption will be given not less than 30 nor more than 60
calendar days prior to the date fixed for redemption or within the Redemption
Notice Period specified on the face hereof, which date and the applicable
redemption price will be specified in the notice.

     If the face hereof indicates that this Note is subject to "Tax Redemption
and Payment of Additional Amounts," the Issuer will, subject to certain
exceptions and limitations set forth below, pay such additional amounts (the
"Additional Amounts") to the holder of this Note who is a United States Alien as
may be necessary in order that every net payment of the principal of and
interest on this Note and any other amounts payable on this Note, after
withholding or deduction for or on account of any present or future tax,
assessment or governmental charge imposed upon or as a result of such payment by
the United States, or any political subdivision or taxing authority thereof or
therein, will not be less than the amount provided for in this Note to be then
due and payable. The Issuer will not, however, make any payment of Additional
Amounts to any such holder who is a United States Alien for or on account of:

          (a) any present or future tax, assessment or other governmental charge
     that would not have been so imposed but for (i) the existence of any
     present or former connection between such holder, or between a fiduciary,
     settlor, beneficiary, member or shareholder of such holder, if such holder
     is an estate, a trust, a partnership or a corporation for United States
     federal income tax purposes, and the United States, including, without
     limitation, such holder, or such fiduciary, settlor, beneficiary, member or
     shareholder, being or having been a citizen or resident thereof or being or
     having been engaged in a trade or business or present therein or having, or
     having had, a permanent establishment therein or (ii) the presentation by
     or on behalf of the holder of this Note for payment on a date more than 15
     calendar days after the date on which such payment became due and payable
     or the date on which payment thereof is duly provided for, whichever occurs
     later;

          (b) any estate, inheritance, gift, sales, transfer, excise or personal
     property tax or any similar tax, assessment or governmental charge;

          (c) any tax, assessment or other governmental charge imposed by reason
     of such holder's past or present status as a personal holding company or
     foreign personal holding company or controlled foreign corporation or

     Code of 1986, as amended;

          (d) any tax, assessment or other governmental charge that is payable
     otherwise than by withholding or deduction from payments on or in respect
     of this Note;

          (e) any tax, assessment or other governmental charge required to be
     withheld by any Paying Agent from any payment of principal of, or interest
     on, this Note, if such payment can be made without such withholding by any
     other Paying Agent in a city in Western Europe;

          (f) any tax, assessment or other governmental charge that would not
     have been imposed but for the failure to comply with certification,
     information or other reporting requirements concerning the nationality,
     residence or identity of the holder or beneficial owner of this Note, if
     such compliance is required by statute or by regulation of the United
     States or of any political subdivision or taxing authority thereof or
     therein as a precondition to relief or exemption from such tax, assessment
     or other governmental charge;

          (g) any tax, assessment or other governmental charge imposed by reason
     of such holder's past or present status as the actual or constructive owner

     entitled to vote of the Issuer or as a direct or indirect subsidiary of the
     Issuer; or

          (h) any combination of items (a), (b), (c), (d), (e), (f) or (g).

In addition, the Issuer shall not be required to make any payment of Additional
Amounts (i) to any such holder where such withholding or deduction is imposed on
a payment to an individual and is required to be made pursuant to any law
implementing or complying with, or introduced in order to conform to, any
European Union Directive on the taxation of savings; or (ii) by or on behalf of
a holder who would have been able to avoid such withholding or deduction by
presenting this Note or the relevant coupon to another Paying Agent in a member
state of the European Union. Nor shall the Issuer pay Additional Amounts with
respect to any payment on this Note to a United States Alien who is a fiduciary
or partnership or other than the sole beneficial owner of such payment to the
extent such payment would be required by the laws of the United States (or any
political subdivision thereof) to be included in the income, for tax purposes,
of a beneficiary or settlor with respect to such fiduciary or a member of such
partnership or a beneficial owner who would not have been entitled to the
Additional Amounts had such beneficiary, settlor, member or beneficial owner
been the holder of this Note.

     The Senior Indenture permits the Issuer and the Trustee, with the consent
of the holders of not less than a majority in aggregate principal amount of the
debt securities of all series issued under the Senior Indenture then outstanding
and affected (voting as one class), to execute supplemental indentures adding
any provisions to or changing in any manner the rights of the holders of each
series so affected; provided that the Issuer and the Trustee may not, without
the consent of the holder of each outstanding debt security affected thereby,
(a) extend the final maturity of any such debt security, or reduce the principal
amount thereof, or reduce the rate or extend the time of payment of interest
thereon, or reduce any amount payable on redemption thereof, or change the
currency of payment thereof, or modify or amend the provisions for

                                       32
<PAGE>

conversion of any currency into any other currency, or modify or amend the
provisions for conversion or exchange of the debt security for securities of the
Issuer or other entities or for other property or the cash value of the property
(other than as provided in the antidilution provisions or other similar
adjustment provisions of the debt securities or otherwise in accordance with the
terms thereof), or impair or affect the rights of any holder to institute suit
for the payment thereof or (b) reduce the aforesaid percentage in principal
amount of debt securities the consent of the holders of which is required for
any such supplemental indenture.

     Except as set forth below, if the principal of, premium, if any, or
interest on this Note is payable in a Specified Currency other than U.S. dollars
and such Specified Currency is not available to the Issuer for making payments
hereon due to the imposition of exchange controls or other circumstances beyond
the control of the Issuer or is no longer used by the government of the country
issuing such currency or for the settlement of transactions by public
institutions within the international banking community, then the Issuer will be
entitled to satisfy its obligations to the holder of this Note by making such
payments in U.S. dollars on the basis of the Market Exchange Rate on the date of
such payment or, if the Market Exchange Rate is not available on such date, as
of the most recent practicable date; provided, however, that if the euro has
been substituted for such Specified Currency, the Issuer may at its option (or
shall, if so required by applicable law) without the consent of the holder of
this Note effect the payment of principal of, premium, if any, or interest on
any Note denominated in such Specified Currency in euro in lieu of such
Specified Currency in conformity with legally applicable measures taken pursuant
to, or by virtue of, the Treaty establishing the European Community, as amended.
Any payment made under such circumstances in U.S. dollars or euro where the
required payment is in an unavailable Specified Currency will not constitute an
Event of Default. If such Market Exchange Rate is not then available to the
Issuer or is not published for a particular Specified Currency, the Market
Exchange Rate will be based on the highest bid quotation in The City of New York
received by the Exchange Rate Agent at approximately 11:00 a.m., New York City
time, on the second Business Day preceding the date of such payment from three
recognized foreign exchange dealers (the "Exchange Dealers") for the purchase by
the quoting Exchange Dealer of the Specified Currency for U.S. dollars for
settlement on the payment date, in the aggregate amount of the Specified
Currency payable to those holders or beneficial owners of Notes and at which the
applicable Exchange Dealer commits to execute a contract. One of the Exchange
Dealers providing quotations may be the Exchange Rate Agent unless the Exchange
Rate Agent is an affiliate of the Issuer. If those bid quotations are not
available, the Exchange Rate Agent shall determine the market exchange rate at
its sole discretion.

     The "Exchange Rate Agent" shall be Morgan Stanley & Co. Incorporated,
unless otherwise indicated on the face hereof.

     All determinations referred to above made by, or on behalf of, the Issuer
or by, or on behalf of, the Exchange Rate Agent shall be at such entity's sole
discretion and shall, in the absence of manifest error, be conclusive for all
purposes and binding on holders of Notes and coupons.

     So long as this Note shall be outstanding, the Issuer will cause to be
maintained an office or agency for the payment of the principal of and premium,
if any, and interest on this Note as herein provided in the Borough of
Manhattan, The City of New York, and an office or agency in

                                       33
<PAGE>

said Borough of Manhattan for the registration, transfer and exchange as
aforesaid of the Notes. The Issuer may designate other agencies for the payment
of said principal, premium and interest at such place or places (subject to
applicable laws and regulations) as the Issuer may decide. So long as there
shall be such an agency, the Issuer shall keep the Trustee advised of the names
and locations of such agencies, if any are so designated. If any European Union
Directive on the taxation of savings comes into force, the Issuer will, to the
extent possible as a matter of law, maintain a Paying Agent in a member state of
the European Union that will not be obligated to withhold or deduct tax pursuant
to any such Directive or any law implementing or complying with, or introduced
in order to conform to, such Directive.

     With respect to moneys paid by the Issuer and held by the Trustee or any
Paying Agent for payment of the principal of or interest or premium, if any, on
any Notes that remain unclaimed at the end of two years after such principal,
interest or premium shall have become due and payable (whether at maturity or
upon call for redemption or otherwise), (i) the Trustee or such Paying Agent
shall notify the holders of such Notes that such moneys shall be repaid to the
Issuer and any person claiming such moneys shall thereafter look only to the
Issuer for payment thereof and (ii) such moneys shall be so repaid to the
Issuer. Upon such repayment all liability of the Trustee or such Paying Agent
with respect to such moneys shall thereupon cease, without, however, limiting in
any way any obligation that the Issuer may have to pay the principal of or
interest or premium, if any, on this Note as the same shall become due.

     No provision of this Note or of the Senior Indenture shall alter or impair
the obligation of the Issuer, which is absolute and unconditional, to pay the
principal of, premium, if any, and interest on this Note at the time, place, and
rate, and in the coin or currency, herein prescribed unless otherwise agreed
between the Issuer and the registered holder of this Note.

     Prior to due presentment of this Note for registration of transfer, the
Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the
holder in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and none of the Issuer, the
Trustee or any such agent shall be affected by notice to the contrary.

     No recourse shall be had for the payment of the principal of, premium, if
any, or the interest on this Note, for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Senior Indenture or any
indenture supplemental thereto, against any incorporator, shareholder, officer
or director, as such, past, present or future, of the Issuer or of any successor
corporation, either directly or through the Issuer or any successor corporation,
whether by virtue of any constitution, statute or rule of law or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

     This Note shall for all purposes be governed by, and construed in
accordance with, the laws of the State of New York.

     As used herein, the term "United States Alien" means any person who is, for
United States federal income tax purposes, (i) a nonresident alien individual,
