                      6% Reset PERQS due May 30, 2001
                       Mandatorily Exchangeable For
             Shares of Common Stock of SUN MICROSYSTEMS, INC.
  Reset Performance Equity-linked Redemption Quarterly-pay Securities(SM)
                            ("Reset PERQS(SM)")

The Reset PERQS will pay 6% interest per year but do not guarantee any return
of principal at  maturity.  Instead the Reset PERQS will pay at maturity a
number of shares of Sun Microsystems common stock based on the closing prices
of Sun Microsystems common stock after one year and at maturity, in each case
subject to a cap price.

o The principal amount and issue price of each Reset PERQS is $       ,
  which is one-tenth of the closing price of Sun Microsystems common stock on
  the day we offer the Reset PERQS for initial sale to the public.

o We will pay 6% interest (equivalent to $      per year) on the $
  principal amount of  each Reset PERQS.  Interest will be paid quarterly,
  beginning August 30, 1999.

o At maturity you will receive shares of Sun Microsystems common stock in
  exchange for each Reset PERQS at an exchange ratio.  The initial exchange
  ratio is one-tenth of a share of Sun Microsystems common stock per Reset
  PERQS.  However, if the price of Sun Microsystems common stock
  appreciates above the first year cap price for May 30, 2000 or the second
  year cap price for May 25, 2001, the exchange ratio will be adjusted
  downward, and you will receive an amount of Sun Microsystems common stock
  per Reset PERQS that is less than one-tenth of a share.

o The first year cap price is $      , or    % of the closing price of
  Sun Microsystems common stock on the day we offer the Reset PERQS for
  initial sale to the public.  If on May 30, 2000, the price of Sun
  Microsystems common stock is higher than the closing price of Sun
  Microsystems common stock on the day we offer the Reset PERQS for initial
  sale to the public, we will raise the cap price to     % of the closing
  price of Sun Microsystems common stock on May 30, 2000.  Otherwise the
  cap price will remain unchanged in the second year.  The maximum you can
  receive at maturity is Sun Microsystems common stock worth $     per Reset
  PERQS.

o Investing in Reset PERQS is not equivalent to investing in Sun Microsystems
  common stock.

o Sun Microsystems, Inc. is not involved in this offering of Reset PERQS in
  any way and will have no financial obligation with respect to the Reset
  PERQS.

o We will apply to list the Reset PERQS to trade on the American Stock
  Exchange, Inc. under the proposed AMEX symbol "RPS," but it is not
  possible to predict whether the Reset PERQS will meet the AMEX listing
  requirements.

You should read the more detailed description of the Reset PERQS in this
Pricing Supplement. In particular, you should review and understand the
descriptions in"Summary of Pricing Supplement" and "Description of Reset
PERQS."  "Reset Performance Equity-linked Redemption Quarterly-pay Securities"
and "Reset PERQS" are our service marks.

                       SUMMARY OF PRICING SUPPLEMENT

               The following summary describes the Reset PERQS we are offering
to you in general terms only.  You should read the summary together with the
more detailed information that is contained in the rest of this pricing
supplement and in the accompanying prospectus and prospectus supplement.  You
should carefully consider, among other things, the matters set forth in "Risk
Factors."

               The Reset PERQS offered are medium-term debt securities of
Morgan Stanley Dean Witter & Co.  The return on the Reset PERQS is linked to
the performance of Sun Microsystems, Inc. common stock, which we refer to as
Sun Microsystems Stock.  The Reset PERQS also provide fixed quarterly payments
at an annual rate of 6% based on the principal amount of each Reset PERQS.
Unlike ordinary debt securities, Reset PERQS do not guarantee the return of
principal at maturity.  Instead the Reset PERQS pay a number of shares of Sun
Microsystems Stock at maturity based on the performance of this stock, either
up or down, subject to a maximum value in each year. We may not redeem the
Reset PERQS prior to maturity.

Each Reset PERQS         We, Morgan Stanley Dean Witter & Co., are offering
costs $                  6% Reset Performance Equity-linked Redemption
                         Quarterly-pay Securities[SM] due May 30, 2001,
                         which we refer to as the Reset PERQS[SM].  The
                         principal amount and issue price of each Reset
                         PERQS is $ , which is one-tenth of the closing
                         price of Sun Microsystems Stock on the day we
                         offer the Reset PERQS for initial sale to the
                         public.

No guaranteed            Unlike ordinary debt securities, the Reset PERQS
return of principal      do not guarantee any return of principal at
                         maturity.  Instead the Reset PERQS will pay an
                         amount of Sun Microsystems Stock based on the
                         market price of Sun Microsystems Stock, either up
                         or down, after one year and at maturity, in each
                         case subject to a cap price.  Investing in Reset
                         PERQS is not equivalent to investing in Sun
                         Microsystems Stock.

6% interest on the       We will pay interest on the Reset PERQS, at the
principal amount         rate of 6% of the principal amount per year,
                         quarterly on each February 28, May 30, August 30,
                         and November 30, beginning August 30, 1999.  The
                         interest rate we pay on the Reset PERQS is more
                         than the current dividend rate on the Sun
                         Microsystems Stock.  The Reset PERQS will mature
                         on May 30, 2001.

Your appreciation        The appreciation potential of each Reset PERQS is
potential is capped      limited in each year by the cap price.  The
                         cap price in year one is $        , or     % of the
                         closing market price of Sun Microsystems Stock on
                         the day we offer the Reset PERQS for initial sale
                         to the public ("First Year Cap Price").  The cap
                         price in year two ("Second Year Cap Price") will
                         be the higher of % of the closing market price of
                         Sun Microsystems Stock on May 30, 2000 and the
                         First Year Cap Price.  The maximum you can receive
                         at maturity is Sun Microsystems Stock worth $ per
                         Reset PERQS.

Payment at Maturity      At maturity, for each $       principal amount of
                         Reset PERQS you hold, we will give to you a number
                         of shares of Sun Microsystems Stock equal to the
                         exchange ratio.  The initial exchange ratio is
                         one-tenth of a share of Sun Microsystems Stock per
                         Reset PERQS and may be adjusted as follows:

                                       First Year Adjustment

                         The exchange ratio will be adjusted downward if
                         the market price of Sun Microsystems Stock exceeds
                         the First Year Cap Price on May 30, 2000.

                         The adjusted exchange ratio will be calculated as
                         follows:

                                                  First Year Cap Price

                         If the market price of Sun Microsystems Stock on
                         May 30, 2000 is the same as or less than the First
                         Year Cap Price, we will not adjust the exchange
                         ratio at the end of the first year.

                                       Second Year Adjustment

                         The exchange ratio may be adjusted downward again
                         at maturity, but only if the market price of Sun
                         Microsystems Stock at maturity exceeds the Second
                         Year Cap Price.  The final exchange ratio will
                         then be calculated as follows:

                                                     Second Year Cap Price
            Final Exchange = Existing Exchange x ------------------------------

                         If the market price of Sun Microsystems Stock at
                         maturity is the same as or less than the Second
                         Year Cap Price, we will not adjust the Exchange
                         Ratio at maturity.

                         On the next page, we have provided a table titled
                         "Hypothetical Payments on the Reset PERQS." The
                         table demonstrates the effect of these adjustments
                         to the exchange ratio under a variety of
                         hypothetical price scenarios.  You should examine
                         the table for examples of how the payout on the
                         Reset PERQS could be affected under these or other
                         potential price scenarios.  This table does not
                         show every situation that may occur.

                               RISK FACTORS

               The Reset PERQS are not secured debt and are riskier than
ordinary debt securities. Because the return to investors is linked to the
performance of Sun Microsystems Stock, there is no guaranteed return of
principal. To the extent that the final market price of Sun Microsystems Stock
at maturity is either less than today's market price or not sufficiently above
today's market price to compensate for a downward adjustment of the exchange
ratio, if any, at May 30, 2000, investors will lose money on their investment.
Investing in Reset PERQS is not equivalent to investing directly in Sun
Microsystems Stock. This section describes the most significant risks relating
to the Reset PERQS.  You should carefully consider whether the Reset PERQS are
suited to your particular circumstances before you decide to purchase them.

Reset PERQS Are Not                 The Reset PERQS combine features of
Ordinary Senior Notes --            equity and debt.  The terms of the
No guaranteed return of             Reset PERQS differ from those of
principal                           ordinary debt securities in that we
                                    will not pay you a fixed amount at
                                    maturity.  Our payment to you at
                                    maturity will be a number of shares of
                                    Sun Microsystems Stock based on the
                                    market price of Sun Microsystems Stock
                                    on May 30, 2000 and at maturity.  If
                                    the final market price of Sun
                                    Microsystems Stock at maturity is
                                    either less than today's market price
                                    or not sufficiently above today's
                                    market price to compensate for a
                                    downward adjustment of the exchange
                                    ratio, if any, at May 30, 2000, we will
                                    pay you an amount of Sun Microsystems
                                    Stock with a value less than the
                                    principal amount of the Reset PERQS.
                                    See "Hypothetical Payments on the Reset
                                    PERQS" above.

Your Appreciation                   The appreciation potential of the Reset
Potential Is Limited                PERQS is limited because of the cap
                                    prices. Even though the $       issue
                                    price of one Reset PERQS is equal to
                                    today's market price of one share of
                                    Sun Microsystems Stock multiplied by
                                    the initial exchange ratio, you may
                                    receive a lessor fractional amount of
                                    Sun Microsystems Stock per Reset PERQS
                                    at maturity if the initial exchange
                                    ratio of one-tenth of a share has been
                                    adjusted downwards.  If the price of
                                    Sun Microsystems Stock appreciates
                                    above both the cap price for May 30,
                                    2000 and the cap price for May 25,
                                    2001, the initial exchange ratio of
                                    one-tenth of a share of Sun
                                    Microsystems Stock per Reset PERQS will
                                    be reduced twice.

                                    The exchange ratio and the final market
                                    price of Sun Microsystems Stock at
                                    maturity will be determined on May 25,
                                    2001, which is two trading days prior
                                    to maturity of the Reset PERQS.  If the
                                    price of Sun Microsystems Stock is
                                    lower on the actual maturity date than
                                    it was on May 25, 2001, the value of
                                    any Sun Microsystems Stock you receive
                                    will be less.  Under no circumstances
                                    will you receive an amount of Sun
                                    Microsystems Stock for each Reset PERQS
                                    worth more than $ as of such second
                                    scheduled trading day prior to
                                    maturity.

Secondary Trading                   There may be little or no secondary
May Be Limited                      market for the Reset PERQS.  Although
                                    we will apply to list the Reset PERQS
                                    on the American Stock Exchange, Inc.,
                                    we may not meet the requirements for
                                    listing.  Even if there is a secondary
                                    market, it may not provide significant
                                    liquidity.  Morgan Stanley & Co.
                                    currently intends to act as a market
                                    maker for Reset PERQS but is not
                                    required to do so.

Market Price of the Reset           Several factors, many of which are beyond
PERQS Influenced by Many            our control, will influence the value
Unpredictable Factors               of the Reset PERQS.  We expect that
                                    generally the market price of the Sun
                                    Microsystems Stock on any day will
                                    affect the value of the Reset PERQS
                                    more than any other single factor.
                                    Because adjustments to the exchange
                                    ratio for the Reset PERQS are tied to
                                    the closing stock prices on two
                                    specific days, however, the Reset PERQS
                                    may trade differently from the
                                    underlying stock.  Other factors that
                                    may influence the value of the Reset
                                    PERQS include:

                                    o  the volatility (frequency and
                                       magnitude of changes in price) of
                                       the Sun Microsystems Stock

                                    o  the dividend rate on Sun Microsystems
                                       Stock

                                    o  economic, financial and political
                                       events that affect stock markets
                                       generally and which may affect the
                                       market price of the Sun Microsystems
                                       Stock

                                    o  interest and yield rates in the
                                       market

                                    o  the time remaining to the maturity of
                                       the Reset PERQS

                                    o  our creditworthiness

                                    These factors will influence the price
                                    you will receive if you sell your Reset
                                    PERQS prior to maturity.  For example,
                                    you may have to sell your Reset PERQS
                                    at a substantial discount from the
                                    principal amount if the market price of
                                    the Sun Microsystems Stock is at,
                                    below, or not sufficiently above the
                                    initial market price.

                                    You cannot predict the future
                                    performance of Sun Microsystems Stock
                                    based on its historical performance.
                                    The price of Sun Microsystems Stock may
                                    decrease so that you will receive at
                                    maturity shares of Sun Microsystems
                                    Stock worth less than the principal
                                    amount of the Reset PERQS.  We cannot
                                    guarantee that the price of Sun
                                    Microsystems Stock will increase so
                                    that you will receive at maturity an
                                    amount in excess of the principal
                                    amount of the Reset PERQS.

                                    Sun Microsystems is not involved in the
                                    offering of the Reset PERQS in any way
                                    and has no obligation to consider your
                                    interest as a holder of Reset PERQS in
                                    taking any corporate actions that might
                                    affect the value of your Reset PERQS.
                                    None of the money you pay for the Reset
                                    PERQS will go to Sun Microsystems.


You Have No                         As a holder of Reset PERQS, you will not
Shareholder Rights                  have voting rights or rights to receive

Limited Antidilution                MS & Co., as calculation agent, will
Adjustments                         adjust the amount payable at maturity
                                    for certain events affecting the Sun
                                    Microsystems Stock, such as stock
                                    splits and stock dividends, and certain
                                    other corporate actions involving Sun
                                    Microsystems, such as mergers.
                                    However, the calculation agent is not
                                    required to make an adjustment for
                                    every corporate event that can affect
                                    the Sun Microsystems Stock.  For
                                    example, the calculation agent is not
                                    required to make any adjustments if Sun
                                    Microsystems or anyone else makes a
                                    partial tender or partial exchange
                                    offer for the Sun Microsystems Stock.
                                    If an event occurs that does not
                                    require the calculation agent to adjust
                                    the amount payable at maturity, the
                                    market price of the Reset PERQS may be
                                    materially and adversely affected.

Potential Conflicts of Interest     As calculation agent, MS & Co. will

                                    and other affiliates may also carry out
                                    hedging activities related to Reset
                                    PERQS, including trading in Sun
                                    Microsystems Stock as well as in other
                                    instruments related to Sun Microsystems
                                    Stock.  MS & Co. and some of our other
                                    subsidiaries also trade Sun
                                    Microsystems Stock and other financial
                                    instruments related to Sun Microsystems
                                    Stock on a regular basis as part of
                                    their general broker dealer and other
                                    businesses.  Any of these activities
                                    could influence MS & Co.'s
                                    determination of adjustments made to
                                    Reset PERQS and, accordingly, could
                                    affect your payout on the Reset PERQS.

Tax Treatment                       You should also consider the tax
                                    consequences of investing in the Reset
                                    PERQS.  There is no direct legal
                                    authority as to the proper tax
                                    treatment of the Reset PERQS, and
                                    therefore significant aspects of the
                                    tax treatment of the Reset PERQS are
                                    uncertain.  We do not plan to request a
                                    ruling from the Internal Revenue
                                    Service ("IRS") regarding the tax
                                    treatment of the Reset PERQS, and the
                                    IRS or a court may not agree with the
                                    tax treatment described in this Pricing
                                    Supplement.  Please read carefully the
                                    section "Description of Reset PERQS--

                                 indenture), upon delivery of each Reset PERQS
                                 to the Trustee, we will apply each $
                                 principal amount of such Reset PERQS as
                                 payment for a number of shares of Sun
                                 Microsystems Stock at the Exchange Ratio.
                                 The initial Exchange Ratio, initially set at
                                 0.1, is subject to adjustment on the First
                                 Year Determination Date and at maturity in
                                 order to cap the value of the Sun
                                 Microsystems Stock to be received upon
                                 delivery of the Reset PERQS at $       per
                                 Reset PERQS (    % of the Issue Price).
                                 Solely for purposes of adjustment upon the
                                 occurrence of certain corporate events, the
                                 number of shares of Sun Microsystems Stock to
                                 be delivered at maturity will also be
                                 adjusted by an Exchange Factor, initially set
                                 at 1.0.  See "Exchange Factor" and
                                 "Antidilution Adjustments" below.

                                 If the First Year Closing Price is less than
                                 or equal to the First Year Cap Price, no
                                 adjustment to the Exchange Ratio will be made
                                 at such time.  If the First Year Closing
                                 Price exceeds the First Year Cap Price, the
                                 Exchange Ratio will be adjusted so that the
                                 new Exchange Ratio will equal the product of
                                 (i) the existing Exchange Ratio and (ii) a
                                 fraction the numerator of which will be the
                                 First Year Cap Price and the denominator of
                                 which will be the First Year Closing Price.
                                 In addition, on the First Year Determination
                                 Date, the Calculation Agent will establish
                                 the "Second Year Cap Price" that will be
                                 equal to the greater of (x)    % of the First
                                 Year Closing Price and (y) the First Year Cap
                                 Price.  Notice of the Second Year Cap Price
                                 and of any such adjustment to the Exchange
                                 Ratio shall promptly be sent by first-class
                                 mail to The Depository Trust Company, New
                                 York, New York (the "Depositary").  If the
                                 Maturity Price is less than or equal to the
                                 Second Year Cap Price, no further adjustment
                                 to the Exchange Ratio will be made.  If the
                                 Maturity Price exceeds the Second Year Cap
                                 Price, the then existing Exchange Ratio will
                                 be adjusted so that the final Exchange Ratio
                                 will equal the product of (i) the existing
                                 Exchange Ratio and (ii) a fraction the
                                 numerator of which will be the Second Year
                                 Cap Price and the denominator of which will
                                 be the Maturity Price. Please review each
                                 example in the table called "Hypothetical
                                 Payments on the Reset PERQS" on PS-5.

                                 All calculations with respect to the Exchange
                                 Ratios for the Reset PERQS will be rounded to
                                 the nearest one hundred-thousandth, with five
                                 one-millionths rounded upwards (e.g. .876545
                                 would be rounded to .87655); all
                                 calculations with respect to the Second
                                 Year Cap Price will be rounded to the
                                 nearest ten-thousandth, with five one-
                                 hundred-thousandths rounded upwards (e.g.
                                 $12.34567 would be rounded to $12.3457);
                                 and all dollar amounts related to payments
                                 at maturity resulting from such
                                 calculations will be rounded to the
                                 nearest cent with one-half cent being
                                 rounded upwards.

                                 We shall, or shall cause the Calculation
                                 Agent to, (i) provide written notice to the
                                 Trustee and to the Depositary, on or prior to
                                 10:30 a.m. on the Trading Day immediately

                                 amount of Sun Microsystems Stock to be
                                 delivered with respect to each $
                                 principal amount of each Reset PERQS and (ii)
                                 deliver such shares of Sun Microsystems Stock
                                 (and cash in respect of interest and any

                                 to the Trustee for delivery to the holders.
                                 The Calculation Agent shall determine the
                                 Exchange Ratio applicable at the maturity of
                                 the Reset PERQS and calculate the Exchange
                                 Factor.

No Fractional Shares..........   Upon delivery of the Reset PERQS to the

Acceleration Event............   If on any date the product of the Market
                                 Price per share of Sun Microsystems Stock and
                                 the Exchange Factor is less than $4.00, the
                                 maturity date of the Reset PERQS will be
                                 deemed to be accelerated to such date, and we
                                 will apply each $       principal amount of
                                 each Reset PERQS as payment for a number of
                                 shares of Sun Microsystems Stock at the then

                                 Because the Calculation Agent is our
                                 affiliate, potential conflicts of interest

                                 with respect to certain determinations and
                                 judgments that the Calculation Agent must
                                 make in making adjustments to the Exchange
                                 Factor or other antidilution adjustments or
                                 determining any Market Price or whether a
                                 Market Disruption Event has occurred.  See
                                 "Antidilution Adjustments" and "Market
                                 Disruption Event" below.  MS & Co. is
                                 obligated to carry out its duties as
                                 Calculation Agent in good faith using its
                                 reasonable judgment.

Antidilution Adjustments......   The Exchange Factor will be adjusted as
                                 follows:

                                    1.  If Sun Microsystems Stock is subject
                                 to a stock split or reverse stock split,
                                 then once such split has become effective,
                                 the Exchange Factor will be adjusted to
                                 equal the product of the prior Exchange
                                 Factor and the number of shares issued in
                                 such stock split or reverse stock split
                                 with respect to one share of Sun
                                 Microsystems Stock.

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

                                    3.  There will be no adjustments to the
                                 Exchange Factor to reflect cash dividends
                                 or other distributions paid with respect
                                 to Sun Microsystems Stock other than
                                 distributions described in clause (v) of
                                 paragraph 5 below and Extraordinary
                                 Dividends as described below.  A cash
                                 dividend or other distribution with
                                 respect to Sun Microsystems Stock will be
                                 deemed to be an "Extraordinary Dividend"
                                 if such dividend or other distribution
                                 exceeds the immediately preceding non-
                                 Extraordinary Dividend for Sun
                                 Microsystems Stock by an amount equal to
                                 at least 10% of the Market Price of Sun
                                 Microsystems Stock (as adjusted for any
                                 subsequent corporate event requiring an
                                 adjustment hereunder, such as a stock
                                 split or reverse stock split) on the
                                 Trading Day preceding the ex-dividend date
                                 for the payment of such Extraordinary
                                 Dividend (the "ex-dividend date").  If an
                                 Extraordinary Dividend occurs with respect
                                 to Sun Microsystems Stock, the Exchange
                                 Factor with respect to Sun Microsystems
                                 Stock will be adjusted on the ex-dividend
                                 date with respect to such Extraordinary
                                 Dividend so that the new Exchange Factor
                                 will equal the product of (i) the then
                                 current Exchange Factor and (ii) a
                                 fraction, the numerator of which is the
                                 Market Price on the Trading Day preceding
                                 the ex-dividend date, and the denominator
                                 of which is the amount by which the Market
                                 Price on the Trading Day preceding the ex-
                                 dividend date exceeds the Extraordinary
                                 Dividend Amount.  The "Extraordinary
                                 Dividend Amount" with respect to an
                                 Extraordinary Dividend for Sun
                                 Microsystems Stock will equal (i) in the
                                 case of cash dividends or other
                                 distributions that constitute regular
                                 dividends, the amount per share of such
                                 Extraordinary Dividend minus the amount
                                 per share of the immediately preceding
                                 non-Extraordinary Dividend for Sun
                                 Microsystems Stock or (ii) in the case of
                                 cash dividends or other distributions that
                                 do not constitute regular dividends, the
                                 amount per share of such Extraordinary
                                 Dividend.  To the extent an Extraordinary
                                 Dividend is not paid in cash, the value of
                                 the non-cash component will be determined
                                 by the Calculation Agent, whose
                                 determination shall be conclusive.  A
                                 distribution on the Sun Microsystems Stock
                                 described in clause (v) of paragraph 5
                                 below that also constitutes an
                                 Extraordinary Dividend shall cause an
                                 adjustment to the Exchange Factor pursuant
                                 only to clause (v) of paragraph 5.

                                    4.  If Sun Microsystems issues rights
                                 or warrants to all holders of Sun
                                 Microsystems Stock to subscribe for or
                                 purchase Sun Microsystems Stock at an
                                 exercise price per share less than the
                                 Market Price of the Sun Microsystems Stock
                                 on both (i) the date the exercise price of
                                 such rights or warrants is determined and
                                 (ii) the expiration date of such rights or
                                 warrants, and if the expiration date of
                                 such rights or warrants precedes the
                                 maturity of the Reset PERQS, then the
                                 Exchange Factor will be adjusted to equal
                                 the product of the prior Exchange Factor
                                 and a fraction, the numerator of which

                                 that each holder of Reset PERQS will
                                 receive at maturity, in respect of each $
                                 principal amount of each Reset PERQS,

                                 Event, including, in the case of a Spin-
                                 off Event, the share of Sun Microsystems
                                 Stock with respect to which the spun-off
                                 security was issued (collectively, the
                                 "Exchange Property") in an amount with a
                                 value equal to (a) if the Exchange Ratio
                                 has not been adjusted prior to maturity,
                                 the Transaction Value or (b) if the
                                 Exchange Ratio has been adjusted, an
                                 amount equal to the product of the final
                                 Exchange Ratio and the Transaction Value.
                                 In addition, following a Reorganization
                                 Event, the method of determining the
                                 Maturity Price will be adjusted so that
                                 the Maturity Price will mean the
                                 Transaction Value as of the second
                                 scheduled Trading Day immediately prior to
                                 maturity, and if the Reorganization Event
                                 occurs prior to the First Year
                                 Determination Date, the First Year Closing
                                 Price will mean the Transaction Value

                                 Determination Date.  Notwithstanding the
                                 above, if the Exchange Property received
                                 in any such Reorganization Event consists
                                 only of cash, the maturity date of the
                                 Reset PERQS will be deemed to be
                                 accelerated to the date on which such cash
                                 is distributed to holders of Sun
                                 Microsystems Stock and holders will

                                 satisfaction of MSDW's obligations under

                                 Transaction Value as of such date and (ii)
                                 the then current Exchange Ratio adjusted
                                 as if such date were the next to occur of
                                 either the First Year Determination Date
                                 or the second scheduled Trading Day prior
                                 to maturity.  If Exchange Property
                                 consists of more than one type of
                                 property, holders of Reset PERQS will
                                 receive at maturity a pro rata share of
                                 each such type of Exchange Property.  If
                                 Exchange Property includes a cash
                                 component, holders will not receive any
                                 interest accrued on such cash component.
                                 "Transaction Value" at any date means (i)
                                 for any cash received in any such
                                 Reorganization Event, the amount of cash
                                 received per share of Sun Microsystems
                                 Stock, as adjusted by the Exchange Factor,
                                 (ii) for any property other than cash or
                                 securities received in any such
                                 Reorganization Event, the market value, as
                                 determined by the Calculation Agent, as of
                                 the date of receipt, of such Exchange
                                 Property received for each share of Sun
                                 Microsystems Stock, as adjusted by the
                                 Exchange Factor and (iii) for any security
                                 received in any such Reorganization Event,
                                 an amount equal to the Market Price, as of
                                 the date on which the Transaction Value is
                                 determined, per share of such security
                                 multiplied by the quantity of such
                                 security received for each share of Sun
                                 Microsystems Stock, as adjusted by the
                                 Exchange Factor.

                                 For purposes of paragraph 5 above, in the
                                 case of a consummated tender or exchange
                                 offer or going-private transaction involving
                                 Exchange Property of a particular type,
                                 Exchange Property shall be deemed to include
                                 the amount of cash or other property paid by
                                 the offeror in the tender or exchange offer
                                 with respect to such Exchange Property (in an
                                 amount determined on the basis of the rate of
                                 exchange in such tender or exchange offer or
                                 going-private transaction).  In the event of
                                 a tender or exchange offer or a going-private
                                 transaction with respect to Exchange
                                 Property in which an offeree may elect to

                                 cash.

                                 No adjustments to the Exchange Factor will be
                                 required unless such adjustment would require
                                 a change of at least 0.1% in the Exchange
                                 Factor then in effect.  The Exchange Factor
                                 resulting from any of the adjustments
                                 specified above will be rounded to the

                                 one-millionths being rounded upward.

                                 No adjustments to the Exchange Factor or
                                 method of calculating the Exchange Ratio will

                                 adjustments specified above do not cover all
                                 events that could affect the Market Price of
                                 the Sun Microsystems Stock, including, without

                                 offer for the Sun Microsystems Stock.

                                 Notwithstanding the foregoing, the amount

                                 of Sun Microsystems Stock having a market
                                 price of  $        as of such second
                                 scheduled Trading Day.

                                 The Calculation Agent shall be solely
                                 responsible for the determination and
                                 calculation of any adjustments to the Exchange

                                 investigation of Sun Microsystems as in your
                                 judgment is appropriate to make an informed
                                 decision with respect to an investment in Sun
                                 Microsystems Stock.

Historical Information........   The following table sets forth the high and
                                 low Market Price during 1996, 1997, 1998 and
                                 1999 through April 28, 1999.  The Market
                                 Price on April 28, 1999 was $61 7/16.  We
                                 obtained the Market Prices listed below from
                                 Bloomberg Financial Markets and we believe
                                 such information to be accurate.  You should
                                 not take the historical prices of Sun
                                 Microsystems Stock as an indication of future
                                 performance. The price of Sun Microsystems
                                 Stock may decrease so that you will receive
                                 at maturity shares of Sun Microsystems Stock
                                 worth less than the principal amount of the
                                 Reset PERQS.  We cannot give you any
                                 assurance that the price of Sun Microsystems
                                 Stock will increase so that at maturity you
                                 will receive an amount in excess of the
                                 principal amount of the Reset PERQS.  Because
                                 your return is linked to the Market Price of
                                 Sun Microsystems Stock on May 30, 2000 and May
                                 25, 2001, there is no guaranteed return of
                                 principal. To the extent that the Maturity
                                 Price of Sun Microsystems Stock is less than
                                 the Initial Sun Microsystems Price or not
                                 sufficiently above the Initial Sun
                                 Microsystems Price to compensate for a
                                 downward adjustment of the Exchange Ratio, if
                                 any, at May 30, 2000 and the shortfall is not
                                 offset by the coupon paid on the Reset PERQS,

                                 Historical prices have been adjusted for two

                                 Stock, which became effective in the fourth

                                 1999, respectively.

                                 We make no representation as to the amount of

                                 pay in the future.  In any event, as a holder
                                 of the Reset PERQS, you will not be entitled
                                 to receive dividends, if any, that may be
                                 payable on Sun Microsystems Stock.

Use of Proceeds and Hedging...   The net proceeds we receive from the sale of
                                 the Reset PERQS will be used for general
                                 corporate purposes and, in part, by us or by
                                 one or more of our affiliates in connection
                                 with hedging our obligations under the Reset
                                 PERQS.  See also "Use of Proceeds" in the
                                 accompanying Prospectus.

                                 On or prior to the date of this Pricing
                                 Supplement, we, through our subsidiaries or
                                 others, may hedge our anticipated exposure in
                                 connection with the Reset PERQS by taking
                                 positions in Sun Microsystems Stock, in
                                 options contracts on Sun Microsystems Stock
                                 listed on major securities markets or
                                 positions in any other instruments that we
                                 may wish to use in connection with such
                                 hedging.  In the event that we pursue such a
                                 hedging strategy, the price at which we are
                                 able to purchase such positions may be a
                                 factor in determining the pricing of the
                                 Reset PERQS.  Purchase activity could
                                 potentially increase the price of Sun
                                 Microsystems Stock, and therefore effectively
                                 increase the level to which Sun Microsystems
                                 Stock must rise before you would receive at
                                 maturity an amount of Sun Microsystems Stock
                                 worth as much as or more than the principal
                                 amount of the Reset PERQS.  Although we have
                                 no reason to believe that our hedging
                                 activity will have a material impact on the
                                 price of Sun Microsystems Stock, we cannot
                                 give any assurance that we will not affect
                                 such price as a result of our hedging
                                 activities.  Through our subsidiaries, we are
                                 likely to modify our hedge position
                                 throughout the life of the Reset PERQS,
                                 including on the First Year Determination
                                 Date, by purchasing and selling the
                                 securities and instruments listed above and
                                 any other available securities and
                                 instruments that we may wish to use in
                                 connection with such hedging.

Supplemental Information
  Concerning Plan of
  Distribution................   In order to facilitate the offering of the
                                 Reset PERQS, the Agent may engage in
                                 transactions that stabilize, maintain or
                                 otherwise affect the price of the Reset PERQS
                                 or the Sun Microsystems Stock.  Specifically,
                                 the Agent may overallot in connection with
                                 the offering, creating a short position in
                                 the Reset PERQS for its own account.  In
                                 addition, to cover allotments or to stabilize
                                 the price of the Reset PERQS, the Agent may
                                 bid for, and purchase, the Reset PERQS or the
                                 Sun Microsystems Stock in the open market.
                                 See "Use of Proceeds and Hedging" above.

                                 The Agent proposes initially to offer the
                                 Reset PERQS directly to the public at the
                                 public offering price set forth on the cover
                                 page hereof plus accrued interest, if any,
                                 from the Original Issue Date; provided that
                                 the price will be $       per Reset PERQS and
                                 the underwriting discounts and commissions
                                 will be $       per Reset PERQS for
                                 purchasers of greater than or equal to
                                 500,000 Reset PERQS in any case single
                                 transaction, subject to the holding period
                                 requirements described below.

                                 Delivery of approximately 98.625% of the
                                 Reset PERQS to a purchaser of 500,000 or more
                                 Reset PERQS at the reduced price (the
                                 "Delivered Reset PERQS") will be made on the
                                 date of delivery of the Reset PERQS referred
                                 to on the cover of this Pricing Supplement.
                                 The balance of approximately 1.375% of the
                                 Reset PERQS (the "Escrowed Reset PERQS")
                                 purchased by each such investor will be held
                                 in escrow at MS & Co. for the benefit of the
                                 investor and delivered to such investor if
                                 the investor and any accounts in which the
                                 investor may have deposited any of its
                                 Delivered Reset PERQS have held all of the
                                 Delivered Reset PERQS for 45 calendar days
                                 following the date of the Pricing Supplement
                                 or any shorter period deemed appropriate by
                                 the Agent.  If an investor or any account in
                                 which the investor has deposited any of its
                                 Delivered Reset PERQS fails to satisfy the
                                 holding period requirement, as determined by
                                 the Agent, all of the investor's Escrowed
                                 Reset PERQS will be forfeited by the investor
                                 and not delivered to it.  The Escrowed Reset
                                 PERQS will instead be delivered to the Agent
                                 for sale to investors.  This forfeiture will
                                 have the effect of increasing the purchase
                                 price per Reset PERQS for such investors to
                                 100% of the principal amount of the Reset
                                 PERQS.  Should investors who are subject to
                                 the holding period requirement sell their
                                 Reset PERQS once the holding period is no
                                 longer applicable, the market price of the
                                 Reset PERQS may be adversely affected.  See
                                 also "Plan of Distribution" in the
                                 accompanying Prospectus Supplement.

                                 the plan has invested.  In addition, employee

                                 assets) purchasing Reset PERQS should
                                 consider the possible implications of owning
                                 the Sun Microsystems Stock.  Thus, any

                                 proposing to invest in the Reset PERQS should
                                 consult with its legal counsel prior to such
                                 investment.

United States Federal
  Income Taxation.............   The following summary is based on the
                                 advice of Davis Polk & Wardwell, special tax
                                 counsel to MSDW ("Tax Counsel"), and is a
                                 general discussion of the principal potential
                                 U.S. federal income tax consequences to U.S.
                                 Holders (as defined below) who are initial
                                 holders of the Reset PERQS purchasing the
                                 Reset PERQS at the Issue Price, and who will
                                 hold the Reset PERQS as capital assets within
                                 the meaning of Section 1221 of the Code.
                                 This summary is based on the Code,
                                 administrative pronouncements, judicial
                                 decisions and currently effective and
                                 proposed Treasury Regulations, changes to any
                                 of which subsequent to the date of this
                                 Pricing Supplement may affect the tax
                                 consequences described herein.  This summary
                                 does not address all aspects of the U.S.
                                 federal income taxation that may be relevant
                                 to a particular holder in light of its
                                 individual circumstances or to certain types
                                 of holders subject to special treatment under
                                 the U.S. federal income tax laws (e.g.,
                                 certain financial institutions, tax-exempt
                                 organizations, dealers in options or
                                 securities, or persons who hold a Reset PERQS
                                 as a part of a hedging transaction, straddle,
                                 conversion or other integrated transaction).
                                 As the law applicable to the U.S. federal
                                 income taxation of instruments such as the
                                 Reset PERQS is technical and complex, the
                                 discussion below necessarily represents only
                                 a general summary.  Moreover, the effect of
                                 any applicable state, local or foreign tax
                                 laws is not discussed.

                                 As used herein, the term "U.S. Holder" means
                                 an owner of a Reset PERQS that is, for U.S.
                                 federal income tax purposes, (i) a citizen or
                                 resident of the United States, (ii) a
                                 corporation or other entity created or
                                 organized under the laws of the United States
                                 or any political subdivision thereof or (iii)
                                 an estate or trust the income of which is
                                 subject to United States federal income
                                 taxation regardless of its source.

                                 General

                                 Pursuant to the terms of the Reset PERQS,
                                 MSDW and every holder of a Reset PERQS agree
                                 (in the absence of an administrative
                                 determination or judicial ruling to the
                                 contrary) to characterize a Reset PERQS for
                                 all tax purposes as an investment unit
                                 consisting of the following components (the
                                 "Components"): (i) a contract (the "Forward
                                 Contract") that requires the holder of the
                                 Reset PERQS to purchase, and MSDW to sell,
                                 for an amount equal to $          (the
                                 "Forward Price"), the Sun Microsystems Stock
                                 at maturity (or, alternatively, upon an
                                 earlier redemption of the Reset PERQS), and
                                 (ii) a deposit with MSDW of a fixed amount of
                                 cash, equal to the Issue Price, to secure the
                                 holder's obligation to  purchase the Sun
                                 Microsystems Stock (the "Deposit").  For this
                                 purpose, MSDW has determined that, of the
                                 quarterly payments on the Reset PERQS,    %
                                 is attributable to interest on the Deposit.
                                 This determination is based on MSDW's
                                 judgment as to, among other things, MSDW's
                                 normal borrowing cost and the value of the
                                 Forward Contract.  Under this
                                 characterization, the remainder of the
                                 quarterly payments on the Reset PERQS
                                 represents payments attributable to the
                                 holders' entry into the Forward Contract (the
                                 "Contract Fees").  Furthermore, based on
                                 MSDW's determination of the relative fair
                                 market values of the Components at the time
                                 of issuance of the Reset PERQS, MSDW will
                                 allocate 100% of the  Issue Price of the
                                 Reset PERQS to the Deposit and none to the
                                 Forward Contract.  MSDW's allocation of the
                                 Issue Price among the Components will be
                                 binding on a holder of the Reset PERQS,
                                 unless such holder timely and explicitly
                                 discloses to the Internal Revenue Service
                                 (the "IRS") that its allocation is different
                                 from MSDW's.  The treatment of the Reset
                                 PERQS described above and MSDW's allocation
                                 are not, however, binding on the IRS or the
                                 courts.  No statutory, judicial or
                                 administrative authority directly addresses
                                 the characterization of the Reset PERQS or
                                 instruments similar to the Reset PERQS for
                                 U.S. federal income tax purposes, and no
                                 ruling is being requested from the IRS with
                                 respect to the Reset PERQS.  Due to the
                                 absence of authorities that directly address
                                 instruments that are similar to the Reset
                                 PERQS, tax counsel is unable to render an
                                 opinion as to the proper U.S. federal income
                                 tax characterization of the Reset PERQS.  As
                                 a result, significant aspects of the U.S.
                                 federal income tax consequences of an
                                 investment in the Reset PERQS are not
                                 certain, and no assurance can be given that
                                 the IRS or the courts will agree with the
                                 characterization described herein.
                                 Accordingly, prospective purchasers are urged
                                 to consult their tax advisors regarding the
                                 U.S. federal income tax consequences of an
                                 investment in the Reset PERQS (including
                                 alternative characterizations of the Reset
                                 PERQS) and with respect to any tax
                                 consequences arising under the laws of any
                                 state, local or foreign taxing jurisdiction.
                                 Unless otherwise stated, the following
                                 discussion is based on the treatment and the
                                 allocation described above.

                                 Tax Treatment of the Reset PERQS

                                 Assuming the characterization of the Reset
                                 PERQS and the allocation of the  Issue Price
                                 as set forth above, Tax Counsel believes that
                                 the following U.S. federal income tax
                                 consequences should result.

                                 Quarterly Payments on the Reset PERQS.  To
                                 the extent attributable to the interest on
                                 the Deposit, quarterly payments on the Reset
                                 PERQS will generally be taxable to a U.S.
                                 Holder as ordinary income at the time accrued
                                 or received in accordance with the U.S.
                                 Holder's method of accounting for U.S.
                                 federal income tax purposes.  Although the
                                 federal income tax treatment of the Contract
                                 Fees is uncertain, MSDW intends to take the
                                 position that the Contract Fees constitute
                                 taxable income to the holders at the time
                                 accrued or received in accordance with the
                                 U.S. Holder's method of accounting for U.S.
                                 federal income tax purposes.

                                 Tax Basis.  Based on MSDW's determination set
                                 forth above, the U.S. Holder's tax basis in
                                 the Forward Contract will be zero, and the
                                 U.S. Holder's tax basis in the Deposit will
                                 be 100% of the  Issue Price.

                                 Settlement of the Forward Contract.  Upon the
                                 maturity of the Forward Contract, a U.S.
                                 Holder would, pursuant to the Forward
                                 Contract, be deemed to have applied the
                                 Forward Price toward the purchase of Sun
                                 Microsystems Stock, and a U.S. Holder would
                                 not recognize any gain or loss with respect
                                 to any Sun Microsystems Stock received
                                 thereon.  With respect to any cash received
                                 upon maturity, a U.S. Holder would recognize
                                 gain or loss.  The amount of such gain or
                                 loss would be the extent to which the amount
                                 of such cash received differs from the pro
                                 rata portion of the Forward Price allocable
                                 to the cash.  Any such gain or loss would
                                 generally be capital gain or loss, as the
                                 case may be.  With respect to any Sun
                                 Microsystems Stock received upon maturity,
                                 the U.S. Holder would have an adjusted tax
                                 basis in such Sun Microsystems Stock equal to
                                 the pro rata portion of the Forward Price
                                 allocable thereto.  The allocation of the
                                 Forward Price between cash and Sun
                                 Microsystems Stock should be based on the
                                 amount of the cash received and the relative
                                 fair market value, as of the maturity, of the
                                 Sun Microsystems Stock.  The U.S. Holder's
                                 holding period of any Sun Microsystems Stock
                                 received would start on the day after the
                                 maturity of the Reset PERQS.

                                 Sale or Exchange of the Reset PERQS.  Upon a
                                 sale or exchange of a Reset PERQS prior to
                                 the maturity of the Reset PERQS, a U.S.
                                 Holder would recognize taxable gain or loss
                                 equal to the difference between the amount
                                 realized on such sale or exchange and such
                                 U.S. Holder's tax basis in the Reset PERQS so
                                 sold or exchanged.  Any such gain or loss
                                 would generally be capital gain or loss, as
                                 the case may be.  Such U.S. Holder's tax
                                 basis in the Reset PERQS would generally
                                 equal the U.S. Holder's tax basis in the
                                 Deposit.  For these purposes, the amount
                                 realized does not include any amount
                                 attributable to accrued but unpaid interest
                                 payments on the Deposit, which would be taxed
                                 as described under "--Quarterly Payments on
                                 the Reset PERQS" above.  It is uncertain
                                 whether the amount realized includes any
                                 amount attributable to accrued but unpaid
                                 Contract Fees.  U.S. Holders should consult
                                 their tax advisers regarding the treatment of
                                 accrued but unpaid Contract Fees upon the
                                 sale or exchange of a Reset PERQS.

                                 Possible Alternative Tax Treatments of an
                                 Investment in the Reset PERQS

                                 Due to the absence of authorities that
                                 directly address the proper characterization
                                 of the Reset PERQS, no assurance can be given
                                 that the IRS will accept, or that a court
                                 will uphold, the characterization and tax
                                 treatment described above.  In particular,
                                 the IRS could seek to analyze the U.S.
                                 federal income tax consequences of owning a
                                 Reset PERQS under Treasury regulations
                                 governing contingent payment debt instruments
                                 (the "Contingent Payment Regulations").

                                 If the IRS were successful in asserting that
                                 the Contingent Payment Regulations applied to
                                 the Reset PERQS, the timing and character of
                                 income thereon would be significantly
                                 affected.  Among other things, a U.S. Holder
                                 would be required to accrue as original issue
                                 discount income, subject to adjustments, at a
                                 "comparable yield" on the  Issue Price.
                                 Furthermore, any gain realized with respect
                                 to the Reset PERQS would generally be treated
                                 as ordinary income.

                                 Even if the Contingent Payment Regulations do
                                 not apply to the Reset PERQS, other
                                 alternative federal income tax
                                 characterizations or treatments of the Reset
                                 PERQS are also possible, and if applied could
                                 also affect the timing and the character of
                                 the income or loss with respect to the Reset
                                 PERQS.  It is possible, for example, that a
                                 Reset PERQS could be treated as constituting
                                 a prepaid forward contract. Other alternative
                                 characterizations are also possible.
                                 Accordingly, prospective purchasers are urged
                                 to consult their tax advisors regarding the
                                 U.S. federal income tax consequences of an
                                 investment in the Reset PERQS.

                                 Backup Withholding and Information Reporting

                                 A U.S. Holder of a Reset PERQS may be subject
                                 to information reporting and to backup
                                 withholding at a rate of 31 percent of the
                                 amounts paid to the U.S. Holder, unless such
                                 U.S. Holder provides proof of an applicable
                                 exemption or a correct taxpayer identification
                                 number, and otherwise complies with
                                 applicable requirements of the backup
                                 withholding rules.  The amounts withheld
                                 under the backup withholding rules are not an
                                 additional tax and may be refunded, or
                                 credited against the U.S. Holder's U.S.
                                 federal income tax liability, provided the
                                 required information is furnished to the IRS.
                                 In addition, the effective date of the New
                                 Regulations (as defined in "United States
                                 Federal Taxation -- Backup Withholding" in the
                                 accompanying Prospectus Supplement) has been
                                 changed so that the New Regulations will
                                 apply to payments made after December 31,
                                 1999.
