                          MEDIUM-TERM NOTES, SERIES C

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

               The S&P 500 BRoad InDex Guarded Equity-linked Securities due
December 31, 2003 (the "BRIDGES") are Medium-Term Notes, Series C of Morgan
Stanley, Dean Witter, Discover & Co. (the "Company"), as further described
herein and in the Prospectus Supplement under "Description of Notes--Fixed
Rate Notes" and "-- Notes Linked to Commodity Prices, Single Securities,
Baskets of Securities or Indices."  The BRIDGES are being issued in minimum
denominations of $10 and will mature on December 31, 2003 (the "Maturity
Date").  The issue price of each BRIDGES will be $10 (the "Issue Price"), and
there will be no periodic payments of interest on the BRIDGES.  The BRIDGES
will not be redeemable by the Company in whole or in part prior to the
Maturity Date.

               At maturity, the holder of each BRIDGES will receive $10, the
par amount of such BRIDGES ("Par"), plus an amount (the "Supplemental
Redemption Amount") based on the percentage increase, if any, in the Final
Index Value of the S&P 500 Composite Stock Price Index (the "S&P 500 Index"),
as calculated by Standard & Poor's ("S&P"), a Division of the McGraw-Hill
Companies, Inc., over the Initial Index Value, each as further described
below.  The Supplemental Redemption Amount, if any, payable with respect to
each BRIDGES at maturity will be calculated on the last of the Determination
Dates and will equal the product of Par and  the S&P 500 Index Percent Change.
The S&P 500 Index Percent Change is a fraction, the numerator of which will be
the Final Index Value less the Initial Index Value and the denominator of
which will be the Initial Index Value.  The Supplemental Redemption Amount
cannot be less than zero.  The Initial Index Value has been set to equal
       .  The Final Index Value will equal the arithmetic average of the S&P
500 Index closing values on a date to be specified occurring in the second
quarter of 2001, a date to be specified occurring in the third quarter of 2002
and on December 19, 2003.    See "Determination Dates" herein.  The first two
Determination Dates will be specified in the final Pricing Supplement.

               If the S&P 500 Index Percent Change is equal to or less than
zero, the holder of each BRIDGES will be repaid Par, but will not receive any
Supplemental Redemption Amount.

               For information as to the calculation of the Supplemental
Redemption Amount, the S&P 500 Index Percent Change, the Final Index Value and
certain tax consequences to beneficial owners of the BRIDGES, see "Supplemental
Redemption Amount," "S&P 500 Index Percent Change," "Final Index Value" and
"United States Federal Taxation" in this Pricing Supplement.

               The Company will cause the Supplemental Redemption Amount, the
S&P 500 Index Percent Change and the Final Index Value to be determined by
Morgan Stanley & Co. Incorporated (the "Calculation Agent") for The Chase
Manhattan Bank, as Trustee under the Senior Debt Indenture.

               An investment in the BRIDGES entails risks not associated with
similar investments in a conventional debt security, as described under "Risk
Factors" on PS-7 and PS-8 herein.

               Application will be made to list the BRIDGES on the New York
Stock Exchange ("NYSE"), subject to meeting the NYSE listing requirements.  It
is not possible to predict whether the BRIDGES will meet the NYSE listing
requirements or trade in the secondary market or if such market will be liquid
or illiquid.

               "BRIDGES" and "BRoad InDex Guarded Equity-linked Securities" are
service marks of the Company.

S&P 500 Index Percent Change..   The S&P 500 Index Percent Change is a
                                 fraction, the numerator of which will be the

                                 Value and the denominator of which will be
                                 the Initial Index Value.  The S&P 500 Index
                                 Percent Change is described by the following
                                 formula:

                                  (Final Index Value - Initial Index Value)

                                 regular official weekday close of trading on
                                 such Determination Date.  See "Discontinuance
                                 of the S&P 500 Index; Alteration of Method of
                                 Calculation."

                                 be deemed to include any Successor Index,
                                 unless the context requires otherwise.

Final Index Value.............   The Final Index Value will equal the
                                 arithmetic average of the Index Closing
                                 Values on each of the Determination Dates as
                                 calculated on the last Determination Date by
                                 the Calculation Agent and rounded to the
                                 nearest one hundredth of a point with five
                                 one thousandths of a point being rounded
                                 upwards.

Determination Dates...........   The Determination Dates will be specified at
                                 the time of pricing and will appear in the
                                 final Pricing Supplement. The first scheduled

                                 may be any date from and including July 1,
                                 2002 through September 30, 2002; and the last
                                 scheduled Determination Date will be December
                                 19, 2003.  The first and second scheduled
                                 Determination Dates will be selected on the
                                 basis of market interest rates and the
                                 volatility of the S&P 500 Index at the time
                                 of pricing.

                                 If either of the first two scheduled
                                 Determination Dates is not a Trading Day or
                                 if a Market Disruption Event occurs on either
                                 such date, such Determination Date will be
                                 the immediately succeeding Trading Day during
                                 which no Market Disruption Event shall have
                                 occurred; provided that if a Market
                                 Disruption Event has occurred on each of the
                                 five Trading Days immediately succeeding
                                 either of the first two scheduled
                                 Determination Dates, then (i) such fifth
                                 succeeding Trading Day will be deemed to be
                                 the relevant Determination Date,
                                 notwithstanding the occurrence of a Market
                                 Disruption Event on such day and (ii) with
                                 respect to any such fifth Trading Day on
                                 which a Market Disruption Event occurs, the
                                 Calculation Agent will determine the value of
                                 the S&P 500 Index on such fifth Trading Day
                                 in accordance with the formula for and method
                                 of calculating the S&P 500 Index last in
                                 effect prior to the commencement of the
                                 Market Disruption Event, using the closing
                                 price (or, if trading in the relevant
                                 securities has been materially suspended or
                                 materially limited, its good faith estimate
                                 of the closing price that would have
                                 prevailed but for such suspension or
                                 limitation) on such Trading Day of each
                                 security most recently comprising the S&P 500
                                 Index.

                                 If December 19, 2003, the last scheduled
                                 Determination Date, is not a Trading Day or
                                 if there is a Market Disruption Event on such
                                 last scheduled Determination Date, such last
                                 Determination Date will be the immediately
                                 succeeding Trading Day during which no Market
                                 Disruption Event shall have occurred;
                                 provided that the last Determination Date
                                 will be no later than the second scheduled
                                 Trading Day preceding the Maturity Date, and
                                 if such date is not a Trading Day or if there
                                 is a Market Disruption Event on such date,
                                 the Calculation Agent will determine the
                                 value of the S&P 500 Index on such last
                                 Determination Date in accordance with clause
                                 (ii) of the preceding paragraph.

                                 on the New York Stock Exchange ("NYSE"), the
                                 American Stock Exchange, Inc. ("AMEX"), the

                                    limitation of trading of 100 or more of
                                    the securities included in the S&P 500
                                    Index on the primary market for such
                                    securities for more than two hours of
                                    trading or during the one-half hour period
                                    preceding the close of trading in such
                                    market; or the suspension, absence or
                                    material limitation of trading on the
                                    primary market for trading in futures or
                                    options contracts related to the S&P 500
                                    Index during the one-half hour period
                                    preceding the close of trading in the
                                    applicable market, in each case as
                                    determined by the Calculation Agent in its
                                    sole discretion; and

                                    (ii) a determination by the Calculation
                                    Agent in its sole discretion that the
                                    event described in clause (i) above
                                    materially interfered with the ability of
                                    the Company or any of its affiliates to
                                    unwind all or a material portion of the
                                    hedge with respect to the BRIDGES.

                                 For purposes of determining whether a Market
                                 Disruption Event has occurred:  (1) a
                                 limitation on the hours or number of days of
                                 trading will not constitute a Market
                                 Disruption Event if it results from an
                                 announced change in the regular business
                                 hours of the relevant exchange or market, (2)
                                 a decision to permanently discontinue trading
                                 in the relevant futures or options contract
                                 will not constitute a Market Disruption
                                 Event, (3) limitations pursuant to New York
                                 Stock Exchange Rule 80A (or any applicable
                                 rule or regulation enacted or promulgated by
                                 the NYSE, any other self-regulatory
                                 organization or the Securities and Exchange
                                 Commission of similar scope as determined by
                                 the Calculation Agent) on trading during
                                 significant market fluctuations will
                                 constitute a suspension, absence or material
                                 limitation of trading, (4) a suspension of
                                 trading in a futures or options contract on
                                 the S&P 500 Index by the primary securities
                                 market related to such contract by reason of
                                 (a) a price change exceeding limits set by
                                 such exchange or market, (b) an imbalance of
                                 orders relating to such contracts or (c) a
                                 disparity in bid and ask quotes relating to
                                 such contracts will constitute a suspension
                                 or material limitation of trading in futures
                                 or options contracts related to the S&P 500
                                 Index and (5) a "suspension, absence or
                                 material limitation of trading" on the
                                 primary market on which futures or options
                                 contracts related to the S&P 500 Index are
                                 traded will not include any time when such
                                 market is itself closed for trading under
                                 ordinary circumstances.

Alternative Determination 
Date in case of an Event 
of Default....................   In case an Event of Default with respect to
                                 any BRIDGES shall have occurred and be
                                 continuing, the amount declared due and
                                 payable upon any acceleration of the BRIDGES
                                 will be determined by the Calculation Agent
                                 and will be equal to Par plus the Supplemental
                                 Redemption Amount, if any, determined as
                                 though each Determination Date scheduled to
                                 occur on or after such date of acceleration
                                 were the date of acceleration.

Calculation Agent.............   Morgan Stanley & Co. Incorporated ("MS & Co.")

                                 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 the Company and
                                 holders of the BRIDGES.

                                 Because the Calculation Agent is an affiliate
                                 of the Company, potential conflicts of
                                 interest may exist between the Calculation
                                 Agent and the holders of the BRIDGES,
                                 including with respect to certain
                                 determinations and judgments that the
                                 Calculation Agent must make in determining
                                 the S&P 500 Index Percent Change, the Final
                                 Index Value, the Supplemental Redemption
                                 Amount or whether a Market Disruption Event
                                 has occurred.  See "Discontinuance of the S&P
                                 500 Index; Alteration of Method of
                                 Calculation" below and "Market Disruption
                                 Event" above.   MS & Co., as a registered
                                 broker-dealer, is required to maintain
                                 policies and procedures regarding the
                                 handling and use of confidential proprietary
                                 information, and such policies and procedures
                                 will be in effect throughout the term of the
                                 BRIDGES to restrict the use of information
                                 relating to the calculation of the S&P 500
                                 Index Percent Change, the Final Index Value
                                 and the Supplemental Redemption Amount prior
                                 to the dissemination of such information.  MS
                                 & Co. is obligated to carry out its duties
                                 and functions as Calculation Agent in good
                                 faith and using its reasonable judgment.

Risk Factors..................   An investment in the BRIDGES entails
                                 significant risks not associated with similar
                                 investments in a conventional security,
                                 including the following.

                                 If the S&P Index Percent Change is equal to
                                 or less than zero, the holders of the BRIDGES
                                 will receive only the par amount of each
                                 BRIDGES at maturity.

                                 There will be no periodic payments of
                                 interest on the BRIDGES as there would be on
                                 a conventional fixed-rate debt security
                                 having the same maturity date as the BRIDGES
                                 and issued by the Company on the Original
                                 Issue Date. Because the Supplemental
                                 Redemption Amount may be equal to zero, the
                                 effective yield to maturity of the BRIDGES
                                 may be less than that which would be payable
                                 on such a conventional fixed-rate debt
                                 security.

                                 The return of only the par amount of each
                                 BRIDGES at maturity will not compensate the
                                 holder for any opportunity cost implied by
                                 inflation and other factors relating to the
                                 time value of money.  The percentage
                                 appreciation of the S&P 500 Index based on
                                 the Final Index Value over the Initial Index
                                 Value does not reflect the payment of
                                 dividends on the stocks underlying the S&P
                                 500 Index.  Therefore, the yield to maturity
                                 based on the Final Index Value relative to
                                 the Initial  Index Value will not be the same
                                 yield as would be produced if such underlying
                                 stocks were purchased and held for a similar
                                 period.

                                 The BRIDGES are not currently listed on any
                                 exchange, but the Company intends to apply to
                                 list the BRIDGES on the NYSE, subject to
                                 meeting the NYSE listing requirements.  It is
                                 not possible to predict whether the BRIDGES
                                 will meet the NYSE listing requirements, and
                                 there can be no assurance as to whether there
                                 will be a secondary market in the BRIDGES or
                                 if there were to be such a secondary market,
                                 whether such market would be liquid or
                                 illiquid.  It is expected that the secondary
                                 market for the BRIDGES will be affected by
                                 the creditworthiness of the Company and by a
                                 number of factors, including, but not limited
                                 to, the volatility of the S&P 500 Index,
                                 dividend rates on the stocks underlying the
                                 S&P 500 Index, the time remaining to each
                                 Determination Date and to the maturity of the
                                 BRIDGES and market interest rates.  In
                                 addition, the Final Index Value depends on a
                                 number of interrelated factors, including
                                 economic, financial and political events,
                                 over which the Company has no control.  The
                                 value of the BRIDGES prior to maturity is
                                 expected to depend primarily on market
                                 interest rates, market volatility and the
                                 extent of the appreciation or depreciation of
                                 the S&P 500 Index from the Initial Index
                                 Value on each of the  Determination Dates.
                                 The price at which a holder will be able to
                                 sell the BRIDGES prior to maturity may be at
                                 a discount, which could be substantial, from
                                 the par amount thereof, if, at such time, or
                                 on any previous Determination Date the S&P
                                 500 Index (or the Final Index Value, if
                                 determined) is below, equal to or not
                                 sufficiently above the Initial Index Value,
                                 if market interest rates rise substantially
                                 or if market volatility decreases.

                                 The historical S&P 500 Index values should
                                 not be taken as an indication of the future
                                 performance of the S&P 500 Index during the
                                 term of the BRIDGES.  While the trading
                                 prices of the stocks underlying the S&P 500
                                 Index will determine the value of the S&P 500
                                 Index, it is impossible to predict whether
                                 the value of the S&P 500 Index will rise or
                                 fall.  Trading prices of the stocks underlying
                                 the S&P 500 Index will be influenced by both
                                 the complex and interrelated political,
                                 economic, financial and other factors that can
                                 affect the capital markets generally and the
                                 equity trading markets on which the
                                 underlying stocks are traded, and by various
                                 circumstances that can influence the values
                                 of the underlying stocks in a specific market
                                 segment or a particular underlying stock.

                                 The policies of S&P concerning additions,
                                 deletions and substitutions of the stocks
                                 underlying the S&P 500 Index and the manner
                                 in which S&P takes account of certain changes
                                 affecting such underlying stocks may affect
                                 the value of the S&P 500 Index.  The policies
                                 of S&P with respect to the calculation of the
                                 S&P 500 Index could also affect the value of
                                 the S&P 500 Index.  S&P may discontinue or
                                 suspend calculation or dissemination of the
                                 S&P 500 Index.  Any such actions could affect
                                 the value of the BRIDGES.  See "S&P 500
                                 Index" and "Discontinuance of the S&P 500
                                 Index; Alteration of Method of Calculation"

                                 Because the Calculation Agent is an affiliate
                                 of the Company, potential conflicts of
                                 interest may exist between the Calculation
                                 Agent and the holders of the BRIDGES,
                                 including with respect to certain
                                 determinations and judgments that the
                                 Calculation Agent must make in determining
                                 the S&P 500 Index Percent Change, the Final
                                 Index Value, the Supplement Redemption Amount
                                 or whether a Market Disruption Event has
                                 occurred.  See "Market Disruption Event" and
                                 "Calculation Agent" above and "Discontinuance
                                 of the S&P 500 Index; Alteration of Method of

                                 It is suggested that prospective investors
                                 who consider purchasing the BRIDGES should
                                 reach an investment decision only after
                                 carefully considering the suitability of the
                                 BRIDGES in light of their particular
                                 circumstances.

                                 Investors should also consider the tax
                                 consequences of investing in the BRIDGES.
                                 See "United States Federal Taxation" below.
                                 Taxable investors will be subject to annual
                                 income tax based on the comparable yield of
                                 the BRIDGES even though they will not receive
                                 any payments thereon prior to maturity and at
                                 maturity may only receive the return of the
                                 par amount of the BRIDGES.

S&P 500 Index.................   The S&P 500 Index is published by S&P and is
                                 intended to provide a performance benchmark
                                 for the U.S. equity markets.  The calculation
                                 of the value of the S&P 500 Index (discussed
                                 below in further detail) is based on the
                                 relative value of the aggregate Market Value
                                 (as defined below) of the common stocks of
                                 500 companies (the "Component Stocks") as of
                                 a particular time as compared to the
                                 aggregate average Market Value of the common
                                 stocks of 500 similar companies during the
                                 base period of the years 1941 through 1943.
                                 The "Market Value" of any Component Stock is
                                 the product of the market price per share and
                                 the number of the then outstanding shares of
                                 such Component Stock.  The 500 companies are
                                 not the 500 largest companies listed on the
                                 NYSE and not all 500 companies are listed on
                                 such exchange.  S&P chooses companies for
                                 inclusion in the S&P 500 Index with an aim of
                                 achieving a distribution by broad industry
                                 groupings that approximates the distribution
                                 of these groupings in the common stock
                                 population of the U.S. equity market.  S&P
                                 may from time to time, in its sole
                                 discretion, add companies to, or delete
                                 companies from, the S&P 500 Index to achieve
                                 the objectives stated above.  Relevant
                                 criteria employed by S&P include the
                                 viability of the particular company, the
                                 extent to which that company represents the
                                 industry group to which it is assigned, the
                                 extent to which the company's common stock is
                                 widely-held and the Market Value and trading
                                 activity of the common stock of that company.

                                 The S&P 500 Index is calculated using a
                                 base-weighted aggregate methodology: the
                                 level of the Index reflects the total Market
                                 Value of all 500 Component Stocks relative to
                                 the S&P 500 Index's base period of 1941-43
                                 (the "Base Period").

                                 An indexed number is used to represent the
                                 results of this calculation in order to make
                                 the value easier to work with and track over
                                 time.

                                 The actual total Market Value of the
                                 Component Stocks during the Base Period has
                                 been set equal to an indexed value of 10.
                                 This is often indicated by the notation
                                 1941-43=10.  In practice, the daily
                                 calculation of the S&P 500 Index is computed
                                 by dividing the total Market Value of the
                                 Component Stocks by a number called the Index
                                 Divisor.  By itself, the Index Divisor is an
                                 arbitrary number.  However, in the context of
                                 the calculation of the S&P 500 Index, it is
                                 the only link to the original base period
                                 value of the Index.  The Index Divisor keeps
                                 the Index comparable over time and is the
                                 manipulation point for all adjustments to the
                                 S&P 500 Index ("Index Maintenance").

                                 Index Maintenance includes monitoring and
                                 completing the adjustments for company
                                 additions and deletions, share changes, stock
                                 splits, stock dividends, and stock price
                                 adjustments due to company restructurings or
                                 spinoffs.

                                 To prevent the value of the Index from
                                 changing due to corporate actions, all
                                 corporate actions which affect the total
                                 Market Value of the Index require an Index
                                 Divisor adjustment.  By adjusting the Index
                                 Divisor for the change in total Market Value,
                                 the value of the S&P 500 Index remains
                                 constant.  This helps maintain the value of
                                 the Index as an accurate barometer of stock
                                 market performance and ensures that the
                                 movement of the Index does not reflect the
                                 corporate actions of individual companies in
                                 the Index.  All Index Divisor adjustments are
                                 made after the close of trading and after the
                                 calculation of the closing value of the S&P
                                 500 Index.  Some corporate actions, such as
                                 stock splits and stock dividends, require
                                 simple changes in the common shares
                                 outstanding and the stock prices of the
                                 companies in the Index and do not require
                                 Index Divisor adjustments.

                                 The table below summarizes the types of S&P
                                 500 Index maintenance adjustments and
                                 indicates whether or not an Index Divisor
                                 adjustment is required.

                                 Stock splits and stock dividends do not
                                 affect the Index Divisor of the S&P 500
                                 Index, because following a split or dividend
                                 both the stock price and number of shares
                                 outstanding are adjusted by S&P so that there
                                 is no change in the Market Value of the
                                 Component Stock.  All stock split and
                                 dividend adjustments are made after the close

                                 Each of the corporate events exemplified in

                                 Index Divisor has the effect of altering the
                                 Market Value of the Component Stock and
                                 consequently of altering the aggregate Market

                                 A large part of the S&P 500 Index maintenance
                                 process involves tracking the changes in the
                                 number of shares outstanding of each of the
                                 S&P 500 Index companies.  Four times a year,
                                 on a Friday close to the end of each calendar
                                 quarter, the share totals of companies in the
                                 Index are updated as required by any changes
                                 in the number of shares outstanding.  After
                                 the totals are updated, the Index Divisor is
                                 adjusted to compensate for the net change in
                                 the total Market Value of the Index.  In
                                 addition, any changes over 5% in the current
                                 common shares outstanding for the S&P 500
                                 Index companies are carefully reviewed on a
                                 weekly basis, and when appropriate, an
                                 immediate adjustment is made to the Index

Discontinuance of the 
S&P 500 Index; Alteration 
of Method of Calculation........ If S&P discontinues publication of the S&P
                                 500 Index and S&P or another entity publishes
                                 a successor or substitute index that the
                                 Calculation Agent determines, in its sole
                                 discretion, to be comparable to the
                                 discontinued S&P 500 Index (such index being
                                 referred to herein as a "Successor Index"),
                                 then any subsequent Index Closing Value will
                                 be determined by reference to the value of
                                 such Successor Index at the close of trading
                                 on the NYSE, the AMEX, NASDAQ NMS or the
                                 relevant exchange or market for the Successor
                                 Index on the relevant Determination Date.

                                 Upon any selection by the Calculation Agent
                                 of a Successor Index, the Calculation Agent
                                 will cause written notice thereof to be
                                 furnished to the Trustee, to the Company and
                                 to the holders of the BRIDGES within three
                                 Trading Days of such selection.

                                 If S&P discontinues publication of the S&P
                                 500 Index prior to, and such discontinuance
                                 is continuing on, any Determination Date and
                                 the Calculation Agent determines that no
                                 Successor Index is available at such time,
                                 then on such Determination Date, the
                                 Calculation Agent will determine the Index
                                 Closing Value that would be used in computing
                                 the S&P 500 Index Percent Change on such
                                 Determination Date.  The Index Closing Value
                                 will be computed by the Calculation Agent in
                                 accordance with the formula for and method
                                 of calculating the S&P 500 Index last in
                                 effect prior to such discontinuance, using
                                 the closing price (or, if trading in the
                                 relevant securities has been materially
                                 suspended or materially limited, its good
                                 faith estimate of the closing price that
                                 would have prevailed but for such suspension
                                 or limitation) on such Determination Date of
                                 each security most recently comprising the
                                 S&P 500 Index. Notwithstanding these
                                 alternative arrangements, discontinuance of
                                 the publication of the S&P 500 Index may
                                 adversely affect the value of the BRIDGES.

                                 If at any time the method of calculating the
                                 S&P 500 Index or a Successor Index, or the
                                 value thereof, is changed in a material
                                 respect, or if the S&P 500 Index or a
                                 Successor Index is in any other way modified
                                 so that such index does not, in the opinion
                                 of the Calculation Agent, fairly represent
                                 the value of the S&P 500 Index or such
                                 Successor Index had such changes or
                                 modifications not been made, then, from and
                                 after such time, the Calculation Agent will,
                                 at the close of business in New York City on
                                 each Determination Date make such
                                 calculations and adjustments as, in the good
                                 faith judgment of the Calculation Agent, may
                                 be necessary in order to arrive at a value of
                                 a stock index comparable to the S&P 500 Index
                                 or such Successor Index, as the case may be,
                                 as if such changes or modifications had not
                                 been made, and calculate the Supplemental
                                 Redemption Amount with reference to the S&P
                                 500 Index or such Successor Index, as
                                 adjusted.  Accordingly, if the method of
                                 calculating the S&P 500 Index or a Successor
                                 Index is modified so that the value of such
                                 index is a fraction of what it would have been
                                 if it had not been modified (e.g., due to a
                                 split in the index), then the Calculation
                                 Agent will adjust such index in order to
                                 arrive at a value of the S&P 500 Index or
                                 such Successor Index as if it had not been
                                 modified (e.g., as if such split had not
                                 occurred).

Historical Information........   The following table sets forth the high and
                                 low daily closing values, as well as
                                 end-of-quarter closing values, of the S&P 500
                                 Index for each quarter in the period from
                                 January 1, 1992 through January 9, 1998.  The
                                 Index Closing Values listed below were
                                 obtained from Bloomberg Financial Markets.
                                 The Company believes all such information to
                                 be accurate.  The historical values of the
                                 S&P 500 Index should not be taken as an
                                 indication of future performance, and no
                                 assurance can be given that the S&P 500 Index
                                 will increase sufficiently to cause the
                                 holders of the BRIDGES to receive any

Use of Proceeds and Hedging...   The net proceeds to be received by the
                                 Company from the sale of the BRIDGES will be
                                 used for general corporate purposes and, in
                                 part, by the Company or one or more of its
                                 affiliates in connection with hedging the
                                 Company's obligations under the BRIDGES,
                                 including hedging market risks associated

                                 Supplement, the Company, through its
                                 subsidiaries and others, may hedge some or
                                 all of its anticipated exposure in connection
                                 with the BRIDGES by the purchase and sale of
                                 exchange traded and over the counter options
                                 on the S&P 500 Index, individual stocks
                                 included in the S&P 500 Index, futures
                                 contracts on the S&P 500 Index and options on
                                 such futures contracts or by taking positions
                                 in any other instruments that it may wish to

                                 Company, through its subsidiaries, is likely
                                 to modify its hedge position throughout the
                                 life of the BRIDGES, including  on each
                                 Determination Date, by purchasing and selling
                                 the securities and instruments listed above
                                 and other available securities and
                                 instruments.   Although the Company has no
                                 reason to believe that its hedging activity
                                 will have a material impact on the price of
                                 such options, stocks, futures contracts, and
                                 options on futures contracts or on the value
                                 of the S&P 500 Index, there can be no
                                 assurance that the Company will not affect
                                 such prices as a result of its hedging
                                 activities.  See also "Use of Proceeds" in

License Agreement.............   S&P and MS & Co. have entered into a
                                 non-exclusive license agreement providing for

                                 relationship to the Company is the licensing
                                 of certain trademarks and trade names of S&P

                                 S&P has no obligation to take the needs of

                                 responsible for and has not participated in
                                 the determination of the timing of, prices
                                 at, or quantities of the BRIDGES to be issued
                                 or in the determination or calculation of the
                                 equation by which the BRIDGES are to be
                                 converted into cash.  S&P has no obligation or

                                 the Company has determined that the
                                 "comparable yield" is an annual rate of    %,
                                 compounded semi-annually.  Based on the
                                 Company's determination of the comparable
                                 yield, the "projected payment schedule" for a
                                 BRIDGES (assuming a par amount of $10 or with
                                 respect to each integral multiple thereof)
                                 consists of a projected amount due at
                                 maturity, equal to $    (the "Projected
                                 Amount").

                                 interest that will be deemed to have accrued
                                 with respect to a BRIDGES during each accrual
                                 period, based upon the Company's
