Antidilution Adjustments...........     The Exchange Ratio shall be adjusted as
                                        follows:

                                            1. If Juniper Stock is subject to a
                                        stock split or 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 Juniper Stock.

                                            2. If Juniper Stock is subject (i)
                                        to a stock dividend (issuance of
                                        additional shares of Juniper Stock)
                                        that is given ratably to all holders of
                                        shares of Juniper Stock or (ii) to a
                                        distribution of Juniper Stock as a
                                        result of the triggering of any
                                        provision of the corporate charter of
                                        Juniper, then once the dividend has
                                        become effective and Juniper Stock is
                                        trading ex-dividend, the Exchange Ratio
                                        shall be adjusted so that the new
                                        Exchange Ratio shall equal the prior
                                        Exchange Ratio plus the product of (i)
                                        the number of shares issued with
                                        respect to one share of Juniper Stock
                                        and (ii) the prior Exchange Ratio.

                                            3. There shall be no adjustments to
                                        the Exchange Ratio to reflect cash
                                        dividends or other distributions paid
                                        with respect to Juniper Stock other
                                        than distributions described in clauses
                                        (i), (iv) and (v) of paragraph 5 below

                                        Juniper Stock shall be deemed to be an
                                        "Extraordinary Dividend" if such
                                        dividend or other distribution exceeds
                                        the immediately preceding

                                        Stock, the Exchange Ratio with respect
                                        to Juniper Stock shall be adjusted on

                                        such Extraordinary Dividend so that the
                                        new Exchange Ratio shall equal the
                                        product of (i) the then current
                                        Exchange Ratio and (ii) a fraction, the

                                        preceding the ex-dividend date exceeds
                                        the Extraordinary Dividend Amount. The

     Morgan Stanley Dean Witter & Co., 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 Juniper 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 person entitled thereto


                                     A- 18
<PAGE>


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 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 and any premium 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 U.S. dollars for the Specified Currency for settlement on
such payment date in the amount of the


                                     A- 19
<PAGE>


Specified Currency payable in the absence of such an election to such holder
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.

                              REVERSE OF SECURITY

     This Note is one of a duly authorized issue of Senior Global Medium-Term
Notes, Series C, having maturities more than nine months from the date of issue
(the "Notes") of the Issuer. The Notes are issuable under an Amended and
Restated Senior Indenture, dated as of May 1, 1999, between the Issuer and
JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank), as Trustee
(the "Trustee," which term includes any successor trustee under the Senior
Indenture) (as may be amended or supplemented from time to time, the "Senior
Indenture"), to which Senior Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities of the Issuer, the Trustee and holders of the
Notes and the terms upon which the Notes are, and are to be, authenticated and
delivered. The Issuer has appointed JPMorgan Chase Bank 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 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


                                     A- 22
<PAGE>


accrued and unpaid hereon to the date of repayment. 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 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
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
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
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 principal amount of the


                                     A- 24
<PAGE>


debt securities of each affected series (voting as a single class) 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 or insolvency of the Issuer, shall have occurred and be continuing,
either the Trustee or the holders of not less than 25% in principal amount of
all debt securities issued under the Senior Indenture then outstanding (treated
as one class) 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 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," 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 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


                                     A- 25
<PAGE>


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 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 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 days
prior to the date fixed for redemption or within the Redemption Notice Period
specified on 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 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, be required to make any payment of
Additional Amounts to any such holder for or on account of:

          (a) any such 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) and the United States and
     its possessions, 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 the holder of this Note
     for payment on a date more than 15 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 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;


                                     A- 26
<PAGE>


          (d) any tax, assessment or other governmental charge that is payable
     otherwise than by withholding 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);

nor shall Additional Amounts be paid 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 or
repayment thereof, or change the currency of payment thereof, or modify or
amend the provisions for 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 (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
without the consent of the holder of each debt security so affected 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 (the "EC"), as amended by the treaty on European Union
(as so amended, the "Treaty"). 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 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.


                                     A- 28
<PAGE>


     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, for
United States federal income tax purposes, is a foreign corporation, a
non-resident alien individual, a non-resident alien fiduciary of a foreign
estate or trust, or a foreign partnership one or more of the members of which
is a foreign corporation, a non-resident alien individual or a non-resident
alien fiduciary of a foreign estate or trust.

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