                     9% Reset PERQS due December 30, 2002
                         Mandatorily Exchangeable For
                    Shares of Common Stock of XILINX, INC.

      Reset Performance Equity-linked Redemption Quarterly-pay Securities(SM)
                                 ("Reset PERQS(SM)")

The Reset PERQS will pay 9% 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 Xilinx common stock based on the closing prices of Xilinx
common stock on December 28, 2001 and at maturity, in each case subject to a
cap price.

o    The principal amount and issue price of each Reset PERQS is $13.3375,
     which is one-fifth of the closing price of Xilinx common stock on November
     7, 2000, the day we offered the Reset PERQS for initial sale to the
     public.

o    We will pay 9% interest (equivalent to $1.200375 per year) on the $13.3375
     principal amount of each Reset PERQS. Interest will be paid quarterly,
     beginning December 30, 2000.

o    At maturity you will receive shares of Xilinx common stock in exchange for
     each Reset PERQS at an exchange ratio. The initial exchange ratio is
     one-fifth of a share of Xilinx common stock per Reset PERQS. However, if
     the price of Xilinx common stock appreciates above the first year cap
     price for December 28, 2001 or the second year cap price for December 26,
     2002, the exchange ratio will be adjusted downward, and you will receive
     an amount of Xilinx common stock per Reset PERQS that is less than
     one-fifth of a share.

o    The first year cap price is $95.03, or 142.50% of the closing price of
     Xilinx common stock on November 7, 2000, the day we offered the Reset
     PERQS for initial sale to the public. If on December 28, 2001, the price
     of Xilinx common stock is higher than the closing price of Xilinx common
     stock on November 7, 2000, we will raise the cap price to 142.50% of the
     closing price of Xilinx common stock on December 28, 2001. Otherwise the
     cap price will remain unchanged in the second year. The maximum you can
     receive at maturity is Xilinx common stock worth $27.08 per Reset PERQS.

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

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

o    The Reset PERQS have been approved for listing on the American Stock
     Exchange LLC, subject to official notice of issuance. The AMEX listing
     symbol for the Reset PERQS is "RPX."

descriptions in "Summary of Pricing Supplement" and "Description of Reset

                                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
Xilinx, Inc. common stock, which we refer to as Xilinx Stock. The Reset PERQS
also provide fixed quarterly payments at an annual rate of 9% 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 Xilinx 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.

     "Performance Equity-linked Redemption Quarterly-pay Securities" and
"PERQS" are our service marks.

Each Reset PERQS           We, Morgan Stanley Dean Witter & Co., are offering 9%
costs $13.3375             Reset Performance Equity-linked Redemption
                           Quarterly-pay Securities[SM] due December 30, 2002,
                           which we refer to as the Reset PERQS[SM]. The
                           principal amount and issue price of each Reset PERQS
                           is $13.3375, which is one-fifth of the closing price
                           of Xilinx Stock on November 7, 2000, the day we
                           offered the Reset PERQS for initial sale to the
                           public.

No guaranteed              Unlike ordinary debt securities, the Reset PERQS do
return of principal        not guarantee any return of principal at maturity.
                           Instead the Reset PERQS will pay an amount of Xilinx
                           Stock based on the market price of Xilinx Stock,
                           either up or down, on December 28, 2001 and at
                           maturity, in each case subject to a cap price.
                           Investing in Reset PERQS is not equivalent to

                           30, beginning December 30, 2000. The interest rate
                           we pay on the Reset PERQS is more than the current
                           dividend rate on Xilinx Stock. The Reset PERQS will
                           mature on December 30, 2002.

Your appreciation          The appreciation potential of each Reset PERQS is
potential is capped        limited in each year by the cap price. The cap price
                           through December 28, 2001 is $95.03, or 142.50% of
                           the closing price of Xilinx Stock on the day we
                           offered the Reset PERQS for initial sale to the
                           public ("First Year Cap Price"). The cap price
                           thereafter until maturity ("Second Year Cap Price")
                           will be the higher of 142.50% of the closing price
                           of Xilinx Stock on December 28, 2001 and the First
                           Year Cap Price. The maximum you can receive at
                           maturity is Xilinx Stock worth $27.08 per Reset
                           PERQS.

Payout at maturity         At maturity, for each $13.3375 principal amount of
                           Reset PERQS you hold, we will give to you a number
                           of shares of Xilinx Stock equal to the exchange
                           ratio. The initial exchange ratio is one-fifth of a
                           share of Xilinx Stock per Reset PERQS and may be
                           adjusted as follows:

                              The adjusted exchange ratio will be calculated as

                              Year Cap Price, we will not adjust the exchange
                              ratio at that time.

                           On the next page, we have provided a table titled

                           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

---------
(1) The First Year Closing Price and the Maturity Price do not include any
    dividend payments that may have been paid to holders of Xilinx Stock.


     The above table illustrates an important feature of the Reset PERQS - the
payout at maturity is not determined merely by the price of Xilinx Stock at
maturity, but will depend on the timing and magnitude of changes in Xilinx
Stock price. For example, in both the fourth and seventh illustrations shown
above, the Maturity Price is $65.00 but in the seventh illustration the Payout
at Maturity is $12.86 compared to $15.57 in the fourth illustration. The
difference in the seventh illustration arises because the First Year Closing
Price exceeded the First Year Cap Price, resulting in a downward adjustment in
the Second Year Exchange Ratio. Similarly, in both the ninth and tenth
illustrations, the Payout at Maturity is $29.65, but in the ninth illustration,
the Maturity Price had to equal or exceed $200.00 to produce that payout, while
in the tenth illustration, a Maturity Price of only $135.4178 required.

                                  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
Xilinx Stock, there is no guaranteed return of principal. Investing in Reset
PERQS is not equivalent to investing directly in Xilinx 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 equity and
Ordinary Senior Notes --      debt. The terms of the Reset PERQS differ from
No Guaranteed Return of       those of ordinary debt securities in that we will
Principal                     not pay you a fixed amount at maturity. Our
                              payout to you at maturity will be a number of
                              shares of Xilinx Stock based on the market price
                              of Xilinx Stock on December 28, 2001 and at
                              maturity. If the final market price of Xilinx
                              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
                              December 28, 2001, we will pay you an amount of
                              Xilinx Stock with a value less than the principal
                              amount of the Reset PERQS. See "Hypothetical
                              Payouts on the Reset PERQS" above.

Your Appreciation             The appreciation potential of the Reset PERQS is
Potential Is Limited          limited because of the cap prices. Even though
                              the $13.3375 issue price of one Reset PERQS is
                              equal to today's market price of one share of
                              Xilinx Stock multiplied by the initial exchange
                              ratio, you may receive a lesser fractional amount
                              of Xilinx Stock per Reset PERQS at maturity if
                              the initial exchange ratio of one-fifth of a
                              share has been adjusted downwards. If the price
                              of Xilinx Stock appreciates above both the cap
                              price for December 28, 2001 and the cap price for
                              December 26, 2002, the initial exchange ratio of
                              one-fifth of a share of Xilinx Stock per Reset
                              PERQS will be reduced twice.

                              The exchange ratio and the final market price of
                              Xilinx Stock at maturity will be determined on
                              December 26, 2002, which is two trading days
                              prior to maturity of the Reset PERQS. If the
                              price of Xilinx Stock is lower on the actual
                              maturity date than it was on December 26, 2002,
                              the value of any Xilinx Stock you receive will be
                              less. Under no circumstances will you receive an
                              amount of Xilinx Stock for each Reset PERQS worth
                              more than $27.08 as of December 26, 2002.

Secondary Trading             There may be little or no secondary market for
May Be Limited                the Reset PERQS. Although the Reset PERQS have
                              been approved for listing on the American Stock
                              Exchange LLC, which we refer to as the AMEX, it
                              is not possible to predict whether the Reset
                              PERQS will trade in the secondary market. Even if
                              there is a secondary market, it may not provide
                              significant liquidity. MS & 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 our
PERQS Influenced by Many      control, will influence the value of the Reset
Unpredictable Factors         PERQS. We expect that generally the market price
                              of Xilinx 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 Xilinx Stock.
                              Other factors that may influence the value of the
                              Reset PERQS include:

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

                              o    the dividend rate on Xilinx Stock

                              o    economic, financial, political, regulatory or
                                   judicial events that affect stock markets
                                   generally and which may affect the market
                                   price of Xilinx Stock

                              o    interest and yield rates in the market

                              o    the time remaining to the maturity of the
                                   Reset PERQS

                              o    our creditworthiness

                              Some or all of 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 Xilinx Stock is at, below, or not
                              sufficiently above the initial market price.

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

                                 adjustment on the First Year Determination

                                 order to cap the value of Xilinx Stock to be
                                 received upon delivery of the Reset PERQS at
                                 $27.08 per Reset PERQS (203.0625% of the Issue
                                 Price). Solely for purposes of adjustment upon
                                 the occurrence of certain corporate events,
                                 the number of shares of Xilinx 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," which will be equal
                                 to the greater of (x) 142.50% 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

                                 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 Payouts on the Reset PERQS" on

                                 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., $12.34565 would be rounded to
                                 $12.3457); and all dollar amounts related to
                                 payouts at maturity resulting from such
                                 calculations will be rounded to the nearest

                                 the last reported sale price, regular way, of
                                 the principal trading session on such day on

                                 such last reported sale price is not
                                 obtainable (even if Xilinx Stock (or any such

Trading Day...................   A day, as determined by the Calculation
                                 Agent, on which trading is generally
                                 conducted on the New York Stock Exchange
                                 ("NYSE"), the AMEX, the Nasdaq National
                                 Market, the Chicago Mercantile Exchange and
                                 the Chicago Board of Options Exchange and in

                                 securities in the United States.

Acceleration Event............   If on any date the product of the Market Price
                                 per share of Xilinx 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
                                 the $13.3375 principal amount of each Reset
                                 PERQS as payment for a number of shares of
                                 Xilinx Stock at the then current Exchange
                                 Ratio, as adjusted by the then current

                                 All determinations made by the Calculation
                                 Agent will be at the sole discretion of the
                                 Calculation Agent and will, in the absence of
                                 manifest error, be conclusive for all purposes
                                 and binding on you and on us.

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

                                 an owner of the Reset PERQS, including 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 and functions as
                                 Calculation Agent in good faith and using its
                                 reasonable judgment.

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

                                      1. If Xilinx 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
                                 Xilinx Stock.

                                      2. If Xilinx Stock is subject (i) to a
                                 stock dividend (issuance of additional shares
                                 of Xilinx Stock) that is given ratably to all
                                 holders of shares of Xilinx Stock or (ii) to a
                                 distribution of Xilinx Stock as a result of
                                 the triggering of any provision of the
                                 corporate charter of Xilinx, then once the
                                 dividend has become effective and Xilinx 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 Xilinx
                                 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
                                 Xilinx Stock other than distributions
                                 described in clauses (i) and (v) of paragraph
                                 5 below and Extraordinary Dividends as
                                 described below. A cash dividend or other
                                 distribution with respect to Xilinx Stock will
                                 be deemed to be an "Extraordinary Dividend" if
                                 such dividend or other distribution exceeds
                                 the immediately preceding non- Extraordinary
                                 Dividend for Xilinx Stock by an amount equal
                                 to at least 10% of the Market Price of Xilinx
                                 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 Xilinx Stock,
                                 the Exchange Factor with respect to Xilinx
                                 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 Xilinx 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 Xilinx 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 Xilinx Stock described in
                                 clause (i) or clause (v) of paragraph 5 below
                                 that also constitutes an Extraordinary
                                 Dividend shall cause an adjustment to the
                                 Exchange Factor pursuant only to clause (i) or
                                 clause (v) of paragraph 5, as applicable.

                                      4. If Xilinx issues rights or warrants to
                                 all holders of Xilinx Stock to subscribe for
                                 or purchase Xilinx Stock at an exercise price
                                 per share less than the Market Price of Xilinx
                                 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 shall be the number of shares of
                                 Xilinx Stock outstanding immediately prior to
                                 the issuance of such rights or warrants plus
                                 the number of additional shares of Xilinx
                                 Stock offered for subscription or purchase
                                 pursuant to such rights or warrants and the
                                 denominator of which shall be the number of
                                 shares of Xilinx Stock outstanding immediately
                                 prior to the issuance of such rights or
                                 warrants plus the number of additional shares
                                 of Xilinx Stock which the aggregate offering
                                 price of the total number of shares of Xilinx
                                 Stock so offered for subscription or purchase
                                 pursuant to such rights or warrants would
                                 purchase at the Market Price on the expiration
                                 date of such rights or warrants, which shall
                                 be determined by multiplying such total number
                                 of shares offered by the exercise price of
                                 such rights or warrants and dividing the
                                 product so obtained by such Market Price.

                                 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
                                 determined as of the First Year Determination
                                 Date. Notwithstanding the above, if the

                                 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 Xilinx
                                 Stock and holders will receive in lieu of any

                                 satisfaction of MSDW's obligations under the

                                 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

                                 received per share of Xilinx Stock, as
                                 adjusted by the Exchange Factor at the time of
                                 such Reorganization Event, (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
                                 Xilinx Stock, as adjusted by the Exchange
                                 Factor at the time of such Reorganization
                                 Event 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
                                 Xilinx Stock, as adjusted by the Exchange
                                 Factor at the time of such Reorganization
                                 Event. In the event Exchange Property consists
                                 of securities, those securities will, in turn,
                                 be subject to the antidilution adjustments set
                                 forth in paragraphs 1 through 5.

                                 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 receive cash
                                 or other property, Exchange Property shall be
                                 deemed to include the kind and amount of cash
                                 and other property received by offerees who
                                 elect to receive 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 nearest
                                 one hundred-thousandth with five
                                 one-millionths being rounded upward.

                                 No adjustments to the Exchange Factor or
                                 method of calculating the Exchange Ratio will
                                 be made other than those specified above. The
                                 adjustments specified above do not cover all
                                 events that could affect the Market Price of
                                 Xilinx Stock, including, without limitation, a
                                 partial tender or exchange offer for Xilinx
                                 Stock.

                                 Notwithstanding the foregoing, the amount
                                 payable by us at maturity with respect to each
                                 Reset PERQS, determined as of the second
                                 scheduled Trading Day prior to maturity, will
                                 not under any circumstances exceed an amount
                                 of Xilinx Stock having a market value of
                                 $27.08 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
                                 Factor or method of calculating the Exchange
                                 Ratio and of any related determinations and
                                 calculations with respect to any distributions

                                 or assets (including cash) in connection with
                                 any corporate event described in paragraph 5
                                 above, and its determinations and calculations
                                 with respect thereto shall be conclusive in
                                 the absence of manifest error.

                                 The Calculation Agent will provide information
                                 as to any adjustments to the Exchange Factor

                                 to make an informed decision with respect to
                                 an investment in Xilinx Stock.

Historical Information........   The following table sets forth the high and
                                 low Market Price during 1997, 1998, 1999 and
                                 2000 through November 7, 2000. The Market
                                 Price on November 7, 2000 was 66 11/16. 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 Xilinx Stock
                                 as an indication of future performance. The
                                 price of Xilinx Stock may decrease so that you
                                 will receive at maturity shares of Xilinx
                                 Stock worth less than the principal amount of
                                 the Reset PERQS. We cannot give you any
                                 assurance that the price of Xilinx 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 Xilinx Stock on
                                 December 28, 2001 and December 26, 2002, there
                                 is no guaranteed return of principal. To the
                                 extent that the Maturity Price of Xilinx Stock
                                 is less than the Initial Xilinx Stock Price or
                                 not sufficiently above the Initial Xilinx
                                 Stock Price to compensate for a downward
                                 adjustment of the Exchange Ratio, if any, at
                                 December 28, 2001 and the shortfall is not
                                 offset by the coupon paid on the Reset PERQS,
                                 you will lose money on your investment.

                                 Xilinx has not paid cash dividends on Xilinx
                                 Stock to date. We make no representation as to
                                 the amount of dividends, if any, that Xilinx
                                 will 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 Xilinx 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 subsidiaries in connection
                                 with hedging our

                                 obligations under the Reset PERQS. See also
                                 "Use of Proceeds" in the accompanying
                                 prospectus.

                                 On the date of this pricing supplement, we,
                                 through our subsidiaries or others, hedged our
                                 anticipated exposure in connection with the
                                 Reset PERQS by taking positions in Xilinx
                                 Stock and other instruments. Purchase activity
                                 could have potentially increased the price of
                                 Xilinx Stock, and therefore effectively have
                                 increased the level to which Xilinx Stock must
                                 rise before you would receive at maturity an
                                 amount of Xilinx Stock worth as much as or
                                 more than the principal amount of the Reset
                                 PERQS. 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 Xilinx Stock, option contracts on
                                 Xilinx Stock listed on major securities
                                 markets or positions in any other available
                                 securities or instruments that we may wish to
                                 use in connection with such hedging activity.
                                 Although we have no reason to believe that our
                                 hedging activity had or will have a material
                                 impact on the price of Xilinx Stock, we cannot
                                 give any assurance that we did not, or in the
                                 future will not, affect such price as a result
                                 of our hedging activities.

Supplemental Information
  Concerning of Distribution..   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 $13.10409375 per Reset PERQS
                                 and the underwriting discounts and commissions
                                 will be $.00159375 per Reset PERQS for
                                 purchasers of greater than or equal to 100,000
                                 Reset PERQS in any single transaction, subject
                                 to the holding period requirements described
                                 below.

                                 Delivery of approximately 98.25% of the Reset
                                 PERQS to a purchaser of 100,000 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 1.75% 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.

                                 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 Xilinx Stock. Specifically, the Agent may
                                 sell more Reset PERQS than it is obligated to
                                 purchase in connection with the offering or
                                 may sell Xilinx Stock it does not own,
                                 creating a naked short position in the Reset
                                 PERQS or the Xilinx Stock, respectively, for
                                 its own account. The Agent must close out any
                                 naked short position by purchasing the Reset
                                 PERQS or Xilinx Stock in the open market. A
                                 naked short position is more likely to be
                                 created if the Agent is concerned that there
                                 may be downward pressure on the price of the
                                 Reset PERQS or the Xilinx Stock in the open
                                 market after pricing that could adversely
                                 affect investors who purchase in the offering.
                                 As an additional means of facilitating the
                                 offering, the Agent may bid for, and purchase,
                                 Reset PERQS or Xilinx Stock in the open market
                                 to stabilize the price of the Reset PERQS. Any
                                 of these activities may raise or maintain the
                                 market price of the Reset PERQS above
                                 independent market levels or prevent or retard
                                 a decline in the market price of the Reset
                                 PERQS. The Agent is not required to engage in
                                 these activities, and may end any of these
                                 activities at any time. See "Use of Proceeds
                                 and Hedging" above.

ERISA Matters for Pension
  Plans Insurance Companies...   Each fiduciary of a pension, profit-sharing or
                                 other employee benefit plan subject to the
                                 Employee Retirement Income Security Act of
                                 1974, as amended ("ERISA") (a "Plan"), should
                                 consider the fiduciary standards of ERISA in
                                 the context of the Plan's particular
                                 circumstances before authorizing an investment
                                 in the Reset PERQS. Accordingly, among other
                                 factors, the fiduciary should consider whether
                                 the investment would satisfy the prudence and
                                 diversification requirements of ERISA and
                                 would be consistent with the documents and
                                 instruments governing the Plan.

                                 In addition, we and certain of our
                                 subsidiaries and affiliates, including MS &
                                 Co. and Dean Witter Reynolds Inc. ("DWR"), are
                                 each to be considered a "party in interest"
                                 within the meaning of ERISA, or a
                                 "disqualified person" within the meaning of
                                 the Internal Revenue Code of 1986, as amended
                                 (the "Code") with respect to many Plans.
                                 Prohibited transactions within the meaning of
                                 ERISA or the Code would likely arise, for
                                 example, if the Reset PERQS are acquired by or
                                 with the assets of a Plan with respect to
                                 which MS & Co., DWR or any of their affiliates
                                 is a service provider, unless the Reset PERQS
                                 are acquired pursuant to an exemption from the
                                 "prohibited transaction" rules. A violation of
                                 these "prohibited transaction" rules may
                                 result in an excise tax or other liabilities
                                 under ERISA and/or Section 4975 of the Code
                                 for such persons, unless exemptive relief is
                                 available under an applicable statutory or
                                 administrative exemption.

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

                                 Because we are considered a party in interest
                                 with respect to many Plans, the Reset PERQS
                                 may not be purchased or held by any Plan, any
                                 entity whose underlying assets include "plan
                                 assets" by reason of any Plan's investment in
                                 the entity (a "Plan Asset Entity") or any
                                 person investing "plan assets" of any Plan,
                                 unless such purchaser or holder is eligible
                                 for exemptive relief, including relief
                                 available under PTCE 96-23, 95-60, 91-38, 90-1
                                 or 84-14 or such purchase and holding is
                                 otherwise not prohibited. Any purchaser,
                                 including any fiduciary purchasing on behalf
                                 of a Plan, or holder of the Reset PERQS will
                                 be deemed to have represented, in its
                                 corporate and fiduciary capacity, by its
                                 purchase and holding thereof that it either
                                 (a) is not a Plan or a Plan Asset Entity and
                                 is not purchasing such securities on behalf of
                                 or with "plan assets" of any Plan or (b) is
                                 eligible for exemptive relief or such purchase
                                 or holding is not prohibited by ERISA or
                                 Section 4975 of the Code.

                                 Under ERISA, assets of a Plan may include
                                 assets held in the general account of an
                                 insurance company which has issued an
                                 insurance policy to such plan or assets of an
                                 entity in which the Plan has invested.
                                 Accordingly, insurance company general
                                 accounts that include assets of a Plan must
                                 ensure that one of the foregoing exemptions is
                                 available. Due to the complexity of these
                                 rules and the penalties that may be imposed
                                 upon persons involved in non-exempt prohibited
                                 transactions, it is particularly important
                                 that fiduciaries or other persons considering
                                 purchasing the Reset PERQS on behalf of or
                                 with "plan assets" of any Plan consult with
                                 their counsel regarding the availability of
                                 exemptive relief under PTCE 96-23, 95-60,
                                 91-38, 90-1 or 84-14.

                                 Purchasers of the Reset PERQS have exclusive
                                 responsibility for ensuring that their
                                 purchase and holding of the Reset PERQS do not
                                 violate the prohibited transaction rules of
                                 ERISA or the Code.

                                 Reset PERQS is technical and complex, the
                                 discussion below necessarily represents only a

                                 General

                                 Pursuant to the terms of the Reset PERQS, we
                                 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 us to sell, for an amount equal
                                 to $13.3375 (the "Forward Price"), Xilinx
                                 Stock at maturity (or, alternatively, upon an
                                 earlier redemption of the Reset PERQS), and
                                 (ii) a deposit with us of a fixed amount of
                                 cash, equal to the Issue Price, to secure the
                                 holder's obligation to purchase Xilinx Stock
                                 (the "Deposit"), which Deposit bears an annual
                                 yield of 6.73% per annum, which yield is based
                                 on our cost of borrowing. Under this
                                 characterization, less than the full quarterly
                                 payments on the Reset PERQS will be
                                 attributable to the yield on the Deposit.
                                 Accordingly, the excess of the quarterly
                                 payments on the Reset PERQS over the portion
                                 of those payments attributable to the yield on
                                 the Deposit will represent payments
                                 attributable to the holders' entry into the
                                 Forward Contract (the "Contract Fees").
                                 Furthermore, based on our determination of the
                                 relative fair market values of the Components
                                 at the time of issuance of the Reset PERQS, we
                                 will allocate 100% of the Issue Price of the
                                 Reset PERQS to the Deposit and none to the
                                 Forward Contract. Our 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
                                 IRS that its allocation is different from
                                 ours. The treatment of the Reset PERQS
                                 described above and our 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, you are urged to consult your tax
                                 advisor 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.

                                 U.S. Holders

                                 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 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.

                                 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 yield 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. As discussed above, any excess
                                 of the quarterly payments over the portion
                                 thereof attributable to the yield on the
                                 Deposit will be treated as Contract Fees.
                                 Although the federal income tax treatment of
                                 Contract Fees is uncertain, we intend to take
                                 the position that any Contract Fees with
                                 respect to the Reset PERQS constitute taxable
                                 income to a U.S. Holder 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 our 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 Xilinx
                                 Stock, and a U.S. Holder would not recognize
                                 any gain or loss with respect to any Xilinx
                                 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 Xilinx Stock received upon
                                 maturity, the U.S. Holder would have an
                                 adjusted tax basis in such Xilinx Stock equal
                                 to the pro rata portion of the Forward Price
                                 allocable thereto. The allocation of the
                                 Forward Price between cash and Xilinx Stock
                                 should be based on the amount of the cash
                                 received and the relative fair market value,
                                 as of the maturity, of Xilinx Stock. U.S.
                                 Holders should note that the holding period of
                                 any Xilinx Stock received would start on the
                                 day after the maturity of the Reset PERQS.

                                 U.S. Holders should note that while any
                                 accrued but unpaid interest on the Deposit and
                                 any Contract Fees would be taxable as ordinary
                                 income, any gain or loss recognized upon the
                                 final settlement of the Forward Contract
                                 generally would be capital gain or loss. The
                                 distinction between capital gain or loss and
                                 ordinary gain or loss is potentially
                                 significant in several respects. For example,
                                 limitations apply to a U.S. Holder's ability
                                 to offset capital losses against ordinary
                                 income, and certain U.S. Holders may be
                                 subject to lower U.S. federal income tax rates
                                 with respect to long-term capital gain than
                                 with respect to ordinary gain. U.S. Holders
                                 should consult their tax advisors with respect
                                 to the treatment of capital gain or loss on a
                                 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 advisors 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. In
                                 addition, a U.S. Holder would recognize income
                                 upon maturity of the Reset PERQS to the extent
                                 that the value of Xilinx Stock and cash (if
                                 any) received exceeds the adjusted 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


                                     PS-24

                                 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.

                                 Constructive Ownership

                                 Section 1260 of the Code treats a taxpayer
                                 owning certain types of derivative positions
                                 in property as having "constructive ownership"
                                 in that property, with the result that all or
                                 a portion of the long term capital gain
                                 recognized or deemed to be recognized (as
                                 described below) by such taxpayer with respect
                                 to the derivative position would be
                                 recharacterized as ordinary income. Although
                                 Section 1260 in its current form does not
                                 apply to the Reset PERQS, Section 1260
                                 authorizes the Treasury Department to
                                 promulgate regulations (possibly with
                                 retroactive effect) to expand the application
                                 of the "constructive ownership" regime. There
                                 is no assurance that the Treasury Department
                                 will not promulgate regulations to apply the
                                 regime to the Reset PERQS. If Section 1260
                                 were to apply to the Reset PERQS, the effect
                                 on a U.S. Holder would be to treat all or a
                                 portion of the long term capital gain (if any)
                                 recognized by such U.S. Holder on sale or
                                 maturity of a Reset PERQS as ordinary income,
                                 but only to the extent such long term capital
                                 gain exceeds the long term capital gain that
                                 would have been recognized by such U.S. Holder
                                 if the U.S. Holder had acquired the underlying
                                 stock itself on the issue date of the Reset
                                 PERQS and disposed of the underlying stock
                                 upon disposition (including retirement) of the
                                 Reset PERQS. Section 1260, if applicable,
                                 would require a U.S. Holder that receives
                                 shares of Xilinx Stock at maturity to
                                 recognize as ordinary income the amount that
                                 would have been treated as ordinary income
                                 according to the rule described in the
                                 preceding sentence, if the U.S. Holder had
                                 sold the Reset PERQS at maturity for fair
                                 market value. In addition, Section 1260 would
                                 impose an interest charge on the gain (or
                                 deemed gain) that was recharacterized on the
                                 sale or maturity of 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.
