SUMMARY INFORMATION--Q&A

This summary includes questions and answers that highlight selected
information from the Prospectus and Prospectus Supplement to help you
understand the Market Index Target-Term Securities based upon the Dow Jones
Industrial Average(SM) due January 14, 2003 (the "Securities"). You should
carefully read the Prospectus and Prospectus Supplement to fully understand
the terms of the Securities, the Dow Jones Industrial Average(SM) (the
"DJIA(SM)" or the "Index"), and the tax and other considerations that are
important to you in making a decision about whether to invest in the
Securities. You should, in particular, carefully review the "Risk Factors"
section, which highlights certain risks, to determine whether an investment in
the Securities is appropriate for you.

WHAT ARE THE SECURITIES?

The Securities are a series of senior debt securities issued by Merrill
Lynch & Co., Inc. (the "Company") and are not secured by collateral. The
Securities will rank equally with all other unsecured and unsubordinated debt
of the Company. The Securities mature on January 14, 2003 and do not provide
for earlier redemption. We will make no payments on the Securities until
maturity.

Each "Unit" of Securities represents $10 principal amount of Securities. You
may transfer the Securities only in whole Units. You will not have the right
to receive physical certificates evidencing your ownership except under
limited circumstances. Instead, we will issue the Securities in the form of a
global certificate, which will be held by The Depository Trust Company
("DTC"), or its nominee. Direct and indirect participants in DTC will record
beneficial ownership of the Securities by individual investors. You should
refer to the section "Description of Securities--Depository" in this
Prospectus Supplement.

WHAT WILL I RECEIVE AT MATURITY OF THE SECURITIES?

We have designed the Securities for investors who want to protect their
investment by receiving at least the principal amount of their investment at
maturity and who also want to participate in possible increases in the Index.
At maturity, you will receive a payment on the Securities equal to the sum of
two amounts: the "Principal Amount" and the "Supplemental Redemption Amount".

Principal Amount

The Principal Amount per Unit is $10.

Supplemental Redemption Amount

The Supplemental Redemption Amount per Unit will equal to:

EIV-BIV
$10 x -------
BIV

but will not be less than zero.

EIV = Ending Index Value

BIV = Benchmark Index Value

"ENDING INDEX VALUE" means the average of the values of the Index at the
close of the market on five business days before the maturity of the
Securities. We may calculate the Ending Index Value by reference to fewer than
five or even a single day's closing value if, during the period prior to the
maturity date of the Securities, there is a disruption in the trading of the
component stocks comprising the Index or certain futures or options relating
to the Index.

"BENCHMARK INDEX VALUE" equals 8,594 and was determined as described herein.
The closing value of the Index on the date of this Prospectus Supplement was
7,957.41 (the "Starting Index Value") and the Benchmark Index Value exceeds
the closing value by 8%.

For more specific information about the Supplemental Redemption Amount,
please see the section "Description of Securities" in this Prospectus
Supplement.

The Ending Index Value needs to be more than 8% higher than the Starting
Index Value for any Supplemental Redemption Amount to be paid to you at
maturity. IF THE ENDING INDEX VALUE IS LESS THAN, OR EQUAL TO, THE BENCHMARK
INDEX VALUE, THE SUPPLEMENTAL REDEMPTION AMOUNT WILL BE ZERO. We will pay you
the principal amount of the Securities regardless of whether any Supplemental
Redemption Amount is payable.

S-4
<PAGE>

Examples

Here are three examples of Supplemental Redemption Amount calculations:

Example 1 - The Index is below the Starting Index Value at maturity:
Starting Index Value: 7,957.41
Benchmark Index Value: 8,594
Hypothetical Ending Index Value: 7,900
7,900 - 8,594
Supplemental Redemption Amount (Per Unit) = $10 x ------------- = $0.00
8,594 (Supplemental
Redemption Amount
cannot be less
than zero)
Total payment at maturity (Per Unit) = $10 + $0 = $10

Example 2 - The Index is above the Starting Index Value, but below the
Benchmark Index Value at maturity:
Starting Index Value: 7,957.41
Benchmark Index Value: 8,594
Hypothetical Ending Index Value: 8,400
8,400 - 8,594
Supplemental Redemption Amount (Per Unit) = $10 x ------------- = $0.00
8,594 (Supplemental
Redemption Amount
cannot be less
than zero)
Total payment at maturity (Per Unit) = $10 + $0 = $10

Example 3 - The Index is above the Benchmark Index Value at maturity:
Starting Index Value: 7,957.41
Benchmark Index Value: 8,594
Hypothetical Ending Index Value: 13,527.6
13,527.6 - 8,594
Supplemental Redemption Amount (Per Unit) = $10 x ---------------- = $5.74
8,594

Total payment at maturity (Per Unit) = $10 + $5.74 = $15.74

WHO PUBLISHES THE INDEX AND WHAT DOES THE INDEX MEASURE?
The DJIA(SM) is a price-weighted index published by Dow Jones which means a
component stock's weight in the Index is based on its price per share rather
than the total market capitalization of the issuer of such component stock.
The Index is designed to provide an indication of the composite price
performance of 30 common stocks of corporations representing a broad cross-
section of U.S. industry. The component stocks of the Index are selected by
the editors of The Wall Street Journal ("WSJ"). The corporations represented
in the Index tend to be market leaders in their respective industries and
their stocks are typically widely held by individuals and institutional
investors. The corporations currently represented in the Index are
incorporated in the U.S. and its territories and their stocks are traded on
the New York Stock Exchange (the "NYSE"). As of November 28, 1997, the market
capitalization of the stocks in the Index ranged from approximately
$5.4 billion to $241.4 billion, with the average market capitalization being
$63.7 billion.

The value of the Index is the sum of the primary exchange prices of each of
the 30 common stocks included in the Index, divided by a divisor that is
designed to provide a meaningful continuity in the value of the Index. Because
the Index is price-weighted, stock splits or changes in the component stocks
could result in distortions in the Index value. In order to prevent such
distortions related to extrinsic factors, the divisor may be changed in
accordance with a mathematical formula that reflects adjusted proportions
within the Index. The current divisor of the Index is published daily in the
WSJ and other publications. In addition, other statistics based on the Index
may be found in a variety of publicly available sources.

S-5
<PAGE>

HOW HAS THE INDEX PERFORMED HISTORICALLY?

We have provided a table showing the closing values of the Index on the last
business day of each year from 1946 through 1996, and the closing values of
the Index on the last business day of each month from January 1992 to the
present, as published by Dow Jones.

You can find this table in the section "The Index--Historical Data on the
Index" in this Prospectus Supplement. We have provided this historical
information to help you evaluate the behavior of the Index in various economic
environments; however, past performance of the Index is not necessarily
indicative of how the Index will perform in the future.

WHAT ABOUT TAXES?

Each year, you will be required to pay taxes on ordinary income from the
Securities over their term based upon an estimated yield for the Securities,
even though you will not receive any payments from us until maturity. We have
determined this estimated yield, in accordance with regulations issued by the
Treasury Department, solely in order for you to figure the amount of taxes
that you will owe each year as a result of owning a Security. This amount is
neither a prediction nor a guarantee of what the actual Supplemental
Redemption Amount will be, or that the actual Supplemental Redemption Amount
will even exceed zero. We have determined that this estimated yield will equal
6.18% per annum (compounded semiannually).

Based upon this estimated yield, if you pay your taxes on a calendar year
basis and if you buy a Security for $10 and hold the Security until maturity,
you will be required to pay taxes on the following amounts of ordinary income
from the Securities each year: $0.0144 in 1997, $0.6279 in 1998, $0.6679 in
1999, $0.7098 in 2000, $0.7543 in 2001, $0.8043 in 2002 and $0.0284 in 2003.
However, in 2003, the amount of ordinary income that you will be required to
pay taxes on from owning such Security may be greater or less than $0.0284,
depending upon the Supplemental Redemption Amount, if any, you receive. Also,
if the Supplemental Redemption Amount is less than $3.6070, you may have a
loss which you could deduct against other income you may have in 2003, but
under current tax regulations, you would neither be required nor allowed to
amend your tax returns for prior years. For further information, see "Certain
United States Federal Income Tax Considerations" in this Prospectus
Supplement.

WILL THE SECURITIES BE LISTED ON A STOCK EXCHANGE?

The Securities have been approved for listing on the NYSE under the symbol
"DJM". You should be aware that the listing of the Securities on the NYSE will
not necessarily ensure that a liquid trading market will be available for the
Securities. You should review "Risk Factors--Uncertain Trading Market".

WHAT IS THE ROLE OF OUR SUBSIDIARY, MLPF&S?

Our subsidiary, MLPF&S, is the underwriter for the offering and sale of the
Securities. After the initial offering, MLPF&S intends to buy and sell
Securities to create a secondary market for holders of the Securities, and may
stabilize or maintain the market price of the Securities during the initial
distribution of the Securities. However, MLPF&S will not be obligated to
engage in any of these market activities or continue them once it has started.

MLPF&S will also be our agent (the "Calculation Agent") for purposes of
calculating the Ending Index Value and the Supplemental Redemption Amount.
Under certain circumstances, these duties could result in a conflict of
interest between MLPF&S's status as a subsidiary of the Company and its
responsibilities as Calculation Agent.

CAN YOU TELL ME MORE ABOUT THE COMPANY?

Merrill Lynch & Co., Inc. is a holding company with various subsidiary and
affiliated companies that provide investment, financing, insurance and related
services on a global basis. For information about the Company see the section

New York, New York 10080-6512; telephone number (212) 602-8439.

RISK FACTORS

Your investment in the Securities will involve certain risks. For example,
there is the risk that you might not earn a return on your investment, and the
risk that you will be unable to sell your Securities prior to their maturity.
You should carefully consider the following discussion of risks before
deciding whether an investment in the Securities is suitable for you.

THE SUPPLEMENTAL REDEMPTION AMOUNT.

The Benchmark Index Value exceeds the closing value of the Index (i.e., the
Starting Index Value) on the date the Securities were priced for initial sale
to the public (the "Pricing Date") by 8%. You should be aware that if the
Ending Index Value does not exceed the Starting Index Value at maturity by
more than 8%, the Supplemental Redemption Amount will be zero. This will be
true even if the value of the Index was higher than the Benchmark Index Value
at some time during the life of the Securities but later falls below the
Benchmark Index Value. If the Supplemental Redemption Amount is zero, we will
pay you only the principal amount of your Securities.

YOUR YIELD MAY BE LOWER THAN THE YIELD ON A STANDARD DEBT SECURITY OF
COMPARABLE MATURITY.

The amount we pay you at maturity may be less than the return you could earn
on other investments. Your yield may be less than the yield you would earn if
you bought a standard senior non-callable debt security of the Company with
the same maturity date. Your investment may not reflect the full opportunity
cost to you when you take into account factors that affect the time value of
money.

YOUR RETURN WILL NOT REFLECT THE PAYMENT OF DIVIDENDS.

Dow Jones calculates the Index by reference to the prices of the common
stocks comprising the Index without taking into consideration the value of
dividends paid on those stocks. Therefore, the return you earn on the
Securities, if any, will not be the same as the return that you would earn if
you actually owned each of the common stocks underlying the Index and received
the dividends paid on those stocks.

UNCERTAIN TRADING MARKET.

The Securities have been approved for listing on the NYSE under the symbol
"DJM". While there have been a number of issuances of Market Index Target-Term
Securities, trading volumes have varied historically from one transaction to
another and it is therefore impossible to predict how the Securities will
trade. You cannot assume that a trading market will develop for the
Securities. If such a trading market does develop, there can be no assurance
that there will be liquidity in the trading market. The development of a
trading market for the Securities will depend on the financial performance of
the Company, and other factors such as the appreciation, if any, of the value
of the Index.

S-7
<PAGE>

If the trading market for the Securities is limited, there may be a limited
number of buyers when you decide to sell your Securities if you do not wish to
hold your investment until maturity. This may affect the price you receive.

FACTORS AFFECTING TRADING VALUE OF THE SECURITIES.

We believe that the market value of the Securities will be affected by the
value of the Index and by a number of other factors. Some of these factors are
interrelated in complex ways; as a result, the effect of any one factor may be
offset or magnified by the effect of another factor. The following paragraphs
describe the expected impact on the market value of the Securities given a
change in a specific factor, assuming all other conditions remain constant.

. INDEX VALUE. We expect that the market value of the Securities will
depend substantially on the value of the Index relative to the Benchmark
Index Value. If you choose to sell your Securities when the value of the
Index exceeds the Benchmark Index Value, you may receive substantially
less than the amount that would be payable at maturity based on that
Index value because of the expectation that the Index will continue to
fluctuate until the Ending Index Value is determined. If you choose to
sell your Securities when the value of the Index is below the Benchmark
Index Value, you may receive less than the $10 principal amount per Unit
of Securities. In general, rising U.S. dividend rates (i.e., dividends
per share) may increase the value of the Index while falling U.S.
dividend rates may decrease the value of the Index. Political, economic
and other developments that affect the stocks underlying the Index may
also affect the value of the Index and the value of the Securities.

. INTEREST RATES. Because the Securities repay, at a minimum, the principal
amount at maturity, we expect that the trading value of the Securities
will be affected by changes in interest rates. In general, if U.S.
interest rates increase, we expect that the trading value of the
Securities will decrease. If U.S. interest rates decrease, we expect the
trading value of the Securities will increase. Interest rates may also
affect the U.S. economy and, in turn, the value of the Index. Rising
interest rates may lower the value of the Index and, thus, the
Securities. Falling interest rates may increase the value of the Index
and, thus, may increase the value of the Securities.

. VOLATILITY OF THE INDEX. Volatility is the term used to describe the size
and frequency of market fluctuations. If the volatility of the Index
increases, we expect that the trading value of the Securities will
increase. If the volatility of the Index decreases, we expect that the
trading value of the Securities will decrease.

. TIME REMAINING TO MATURITY. The Securities may trade at a value above
that which would be expected based on the level of interest rates and the
Index. This difference will reflect a "time premium" due to expectations
concerning the value of the Index during the period prior to maturity of
the Securities. However, as the time remaining to maturity of the
Securities decreases, we expect that this time premium will decrease,
lowering the trading value of the Securities.

. DIVIDEND YIELDS. If dividend yields on the stocks comprising the Index
increase, we expect that the value of the Securities will decrease.
Conversely, if dividend yields on the stock comprising the Index
decrease, we expect that the value of the Securities will increase.

. COMPANY CREDIT RATINGS. Real or anticipated changes in the Company's
credit ratings may affect the market value of the Securities.

It is important for you to understand that the impact of one of the factors
specified above, such as an increase in interest rates, may offset some or all
of any increase in the trading value of the Securities attributable to another
factor, such as an increase in the Index value.

In general, assuming all relevant factors are held constant, we expect that
the effect on the trading value of the Securities of a given change in most of
the factors listed above will be less if it occurs later in the term of the
Securities than if it occurs earlier in the term of the Securities except that
we expect that the effect on the trading value of the Securities of a given
increase in the value of the Index will be greater if it occurs later in the
term of the Securities than if it occurs earlier in the term of the
Securities.

STATE LAW LIMITS ON INTEREST PAID.

New York State laws govern the 1983 Indenture, as defined below. New York
has certain usury laws that limit the amount of interest that can be charged
and paid on loans, which includes debt securities like the Securities. Under
present New York law, the maximum rate of interest is 25% per annum on a
simple interest basis. This limit may not apply to debt securities in which
$2,500,000 or more has been invested.

While we believe that New York law would be given effect by a state or
Federal court sitting outside of New York, many other states also have laws
that regulate the amount of interest that may be charged to and paid by a
borrower. We will promise, for the benefit of the holders of the Securities,
to the extent permitted by law, not to voluntarily claim the benefits of any
laws concerning usurious rates of interest.

PURCHASES AND SALES BY MERRILL LYNCH.

The Company, MLPF&S and other affiliates of the Company may from time to
time buy or sell the stocks underlying the Index for their own accounts for
business reasons or in connection with hedging the Company's obligations under
the Securities. These transactions could affect the price of such stocks and
the value of the Index.

POTENTIAL CONFLICTS.

The Calculation Agent is a subsidiary of the Company, the issuer of the
Securities. Under certain circumstances, MLPF&S's role as a subsidiary of the
Company and its responsibilities as Calculation Agent for the Securities could
give rise to conflicts of interests. You should be aware that because the
Calculation Agent is controlled by the Company, potential conflicts of
interest could arise.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth the historical ratios of earnings to fixed
charges of the Company for the periods indicated:

For the purpose of calculating the ratio of earnings to fixed charges,
"earnings" consists of earnings from continuing operations before income taxes
and fixed charges. "Fixed charges" consists of interest costs, amortization of
debt expense, preferred stock dividend requirements of majority-owned
subsidiaries, and that portion of rentals estimated to be representative of
the interest factor.

RECENT DEVELOPMENTS

On November 19, 1997, the Company and Mercury Asset Management Group plc
("MAM") announced the terms of a recommended offer (the "Offer") to be made
for all the issued share capital of MAM. In the proposed transaction, ML
Invest PLC, an indirect, wholly owned subsidiary of the Company, has offered
to acquire all outstanding shares of MAM for a price of (Pounds)17 per share.
The aggregate offer value for the outstanding shares is approximately
(Pounds)3.1 billion.

The directors of MAM have unanimously recommended to MAM shareholders the
acceptance of the Offer and have entered into irrevocable agreements to accept
the Offer in respect of their shareholdings. The transaction is conditioned
on, among other things, the receipt of all required regulatory approvals.

DESCRIPTION OF SECURITIES

GENERAL

The Market Index Target-Term Securities based upon the Dow Jones Industrial
Average(SM) due January 14, 2003, which are referred to herein as the
"Securities" are to be issued as a series of Senior Debt Securities under the
Senior Indenture, referred to as the "1983 Indenture", which is more fully
described in the accompanying Prospectus. The Securities will mature on
January 14, 2003.

While at maturity a beneficial owner of a Security will receive the
principal amount of such Security plus the Supplemental Redemption Amount, if
any, there will be no other payment of interest, periodic or otherwise. See
"Payment at Maturity" below.

The Securities are not subject to redemption by the Company or at the option
of any beneficial owner prior to maturity. Upon the occurrence of an Event of
Default with respect to the Securities, beneficial owners of the Securities
may accelerate the maturity of the Securities, as described under "Description
of Securities--Events of Default and Acceleration" in this Prospectus
Supplement and "Description of Debt Securities--General--Events of Default" in
the accompanying Prospectus.

The Securities are to be issued in denominations of whole Units.

PAYMENT AT MATURITY

At maturity, a beneficial owner of a Security will be entitled to receive
the principal amount thereof plus the Supplemental Redemption Amount, if any,
all as provided below. If the Ending Index Value does not exceed the Benchmark
Index Value, a beneficial owner of a Security will be entitled to receive only
the principal amount thereof.

DETERMINATION OF THE SUPPLEMENTAL REDEMPTION AMOUNT

The Supplemental Redemption Amount for a Security will be determined by the
Calculation Agent and will equal:

<TABLE>
<S> <C>
Ending Index Value-Benchmark Index Value
Principal Amount of such Security ($10 per Unit) X -----------------------------------------
Benchmark Index Value
</TABLE>

provided, however, that in no event will the Supplemental Redemption Amount be
less than zero.

The Benchmark Index Value equals 8,594. The Benchmark Index Value was
determined on the Pricing Date by multiplying the Starting Index Value by a
factor equal to 108%. The Ending Index Value will be determined by the
Calculation Agent and will equal the average (arithmetic mean) of the closing
values of the Index determined on each of the first five Calculation Days
during the Calculation Period. If there are fewer than five Calculation Days,
then the Ending Index Value will equal the average (arithmetic mean) of the
closing values of the Index on such Calculation Days, and if there is only one
Calculation Day, then the Ending Index Value will equal the closing value of
the Index on such Calculation Day. If no Calculation Days occur during the
Calculation Period, then the Ending Index Value will equal the closing value
of the Index determined on the last scheduled Index Business Day in the
Calculation Period, regardless of the occurrence of a Market Disruption Event
on such day. The "Calculation Period" means the period from and including the
seventh scheduled Index Business Day prior to the maturity date to and
including the second scheduled Index Business Day prior to the maturity date.
"Calculation Day" means any Index Business Day during the Calculation Period
on which a Market Disruption Event has not occurred. For purposes of
determining the Ending Index Value, an "Index Business Day" is a day on which
the NYSE and the American Stock Exchange are open for trading and the Index or
any Successor Index, as defined below, is calculated and published. All
determinations made by the Calculation Agent shall be at the sole discretion
of the Calculation Agent and, absent a determination by the Calculation Agent
of a manifest error, shall be conclusive for all purposes and binding on the
Company and beneficial owners of the Securities.

(1) The annualized rates of return specified in the preceding table are
calculated on a semiannual bond equivalent basis.
(2) This rate of return assumes (i) an investment of a fixed amount in the
stocks underlying the Index with the allocation of such amount reflecting
the current relative weights of such stocks in the Index; (ii) a
percentage change in the aggregate price of such stocks that equals the
percentage change in the Index from the Starting Index Value to the
relevant hypothetical Ending Index Value; (iii) a constant dividend yield
of 1.72% per annum, paid quarterly from the date of initial delivery of
Securities, applied to the value of the Index at the end of each such
quarter assuming such value increases or decreases linearly from the
Starting Index Value to the applicable hypothetical Ending Index Value;
(iv) no transaction fees or expenses; (v) a term for the Securities from
December 23, 1997 to January 14, 2003; and (vi) a final Index value equal
to the Ending Index Value. The aggregate dividend yield of the stocks
underlying the Index as of December 17, 1997 was approximately 1.72%.
(3) This is the Starting Index Value.

The above figures are for purposes of illustration only. The actual
Supplemental Redemption Amount received by investors and the total and pretax
annualized rate of return resulting therefrom will depend entirely on the
actual Ending Index Value determined by the Calculation Agent as provided
herein. Historical data regarding the Index is included in this Prospectus
Supplement under "The Index--Historical Data on the Index".

ADJUSTMENTS TO THE INDEX; MARKET DISRUPTION EVENTS

If at any time the method of calculating the Index, or the value thereof, is
changed in any material respect, or if the Index is in any other way modified
so that such Index does not, in the opinion of the Calculation Agent,

S-11
<PAGE>

fairly represent the value of the Index had such changes or modifications not
been made, then, from and after such time, the Calculation Agent shall, at the
close of business in New York, New York, on each date that the closing value
with respect to the Ending Index Value is to be calculated, make such
adjustments as, in the good faith judgment of the Calculation Agent, may be
necessary in order to arrive at a calculation of a value of a stock index
comparable to the Index as if such changes or modifications had not been made,
and calculate such closing value with reference to the Index, as adjusted.
Accordingly, if the method of calculating the Index is modified so that the
value of such Index is a fraction or a multiple 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 shall adjust such Index in order to arrive at a value of the
Index as if it had not been modified (e.g., as if such split had not
occurred).

"Market Disruption Event" means either of the following events; as
determined by the Calculation Agent:

(a) the suspension or material limitation (limitations pursuant to New
York Stock Exchange Rule 80A (or any applicable rule or regulation enacted
or promulgated by the NYSE or any other self regulatory organization or the
SEC of similar scope as determined by the Calculation Agent) on trading
during significant market fluctuations shall be considered "material" for
purposes of this definition), in each case, for more than two hours of
trading, or during the one-half hour period preceding the close of trading
on the applicable exchange, in 20% or more of the stocks which then
comprise the Index; or

(b) the suspension or material limitation, in each case, for more than
two hours of trading (whether by reason of movements in price otherwise
exceeding levels permitted by the relevant exchange or otherwise) in (A)
futures contracts related to the Index, or options on such futures
contracts, which are traded on any major U.S. exchange or (B) option
contracts related to the Index which are traded on any major U.S. exchange.

For the purposes of this definition, a limitation on the hours in a trading
day and/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.

DISCONTINUANCE OF THE INDEX

If Dow Jones discontinues publication of the Index and Dow Jones or another
entity publishes a successor or substitute index that the Calculation Agent
determines, in its sole discretion, to be comparable to such Index (any such
index being referred to herein as a "Successor Index"), then, upon the
Calculation Agent's notification of such determination to the Trustee and the
Company, the Calculation Agent will substitute the Successor Index as
calculated by Dow Jones or such other entity for the Index. Upon any selection
by the Calculation Agent of a Successor Index, the Company shall cause notice
thereof to be given to Holders of the Securities.

If Dow Jones discontinues publication of the Index and a Successor Index is
not selected by the Calculation Agent or is no longer published on any of the
Calculation Days, the value to be substituted for the Index for any such
Calculation Day used to calculate the Supplemental Redemption Amount at
maturity will be a value computed by the Calculation Agent for each
Calculation Day in accordance with the procedures last used to calculate the
Index prior to such discontinuance. If a Successor Index is selected or the
Calculation Agent calculates a value as a substitute for the Index as
described below, such Successor Index or value shall be substituted for the
Index for all purposes, including for purposes of determining whether a Market
Disruption Event exists. If the Calculation Agent calculates a value as a
substitute for the Index, "Index Calculation Day" shall mean any day on which
the Calculation Agent is able to calculate such value.

If Dow Jones discontinues publication of the Index prior to the period
during which the Supplemental Redemption Amount is to be determined and the
Calculation Agent determines that no Successor Index is available at such
time, then on each Business Day until the earlier to occur of (a) the
determination of the Ending Index Value and (b) a determination by the
Calculation Agent that a Successor Index is available, the Calculation Agent
shall determine the value that would be used in computing the Supplemental
Redemption Amount as

S-12
<PAGE>

described in the preceding paragraph as if such day were a Calculation Day.
The Calculation Agent will cause notice of each such value to be published not
less often than once each month in the WSJ (or another newspaper of general
circulation), and arrange for information with respect to such values to be
made available by telephone. Notwithstanding these alternative arrangements,
discontinuance of the publication of the Index may adversely affect trading in
the Securities.

EVENTS OF DEFAULT AND ACCELERATION

In case an Event of Default with respect to any Securities shall have
occurred and be continuing, the amount payable to a beneficial owner of a
Security upon any acceleration permitted by the Securities, with respect to
each $10 principal amount thereof, will be equal to the Principal Amount and
the Supplemental Redemption Amount, if any, calculated as though the date of
early repayment were the stated maturity date of the Securities. See
"Description of Securities--Payment at Maturity" in this Prospectus
Supplement. If a bankruptcy proceeding is commenced in respect of the Company,
the claim of the beneficial owner of a Security may be limited, under Section
502(b)(2) of Title 11 of the United States Code, to the principal amount of
the Security plus an additional amount of contingent interest calculated as
though the date of the commencement of the proceeding were the maturity date
of the Securities.

In case of default in payment at the maturity date of the Securities
(whether at their stated maturity or upon acceleration), from and after the
maturity date the Securities shall bear interest, payable upon demand of the
beneficial owners thereof, at the rate of 6.18% per annum (to the extent that
payment of such interest shall be legally enforceable) on the unpaid amount
due and payable on such date in accordance with the terms of the Securities to
the date payment of such amount has been made or duly provided for.

DEPOSITORY

Upon issuance, all Securities will be represented by one or more fully
registered global securities (the "Global Securities"). Each such Global
Security will be deposited with, or on behalf of, The Depository Trust Company
("DTC"), as Depository, and registered in the name of Cede & Co. (DTC's
partnership nominee). Unless and until it is exchanged in whole or in part for
Securities in definitive form, no Global Security may be transferred except as
a whole by the Depository to a nominee of such Depository or by a nominee of
such Depository to such Depository or another nominee of such Depository or by
such Depository or any such nominee to a successor of such Depository or a
nominee of such successor.

So long as DTC, or its nominee, is a registered owner of a Global Security,
DTC or its nominee, as the case may be, will be considered the sole owner or
Holder of the Securities represented by such Global Security for all purposes
under the 1983 Indenture. Except as provided below, the actual owner of the
Securities represented by a Global Security (the "Beneficial Owner") will not
be entitled to have the Securities represented by such Global Securities
registered in their names, will not receive or be entitled to receive physical
delivery of the Securities in definitive form and will not be considered the
owners or Holders thereof under the 1983 Indenture, including for purposes of
receiving any reports delivered by the Company or the Trustee pursuant to the
1983 Indenture. Accordingly, each person owning a beneficial interest in a
Global Security must rely on the procedures of DTC and, if such person is not
a participant of DTC (a "Participant"), on the procedures of the Participant
through which such person owns its interest, to exercise any rights of a
Holder under the 1983 Indenture. The Company understands that under existing
industry practices, in the event that the Company requests any action of
Holders or than an owner of a beneficial interest in such a Global Security
desires to give or take any action which a Holder is entitled to give or take
under the 1983 Indenture, DTC would authorize the Participants holding the
relevant beneficial interests to give or take such action, and such
Participants would authorize Beneficial Owners owning through such
Participants to give or take such action or would otherwise act upon the
instructions of Beneficial Owners. Conveyance of notices and other
communications by DTC to Participants, by Participants to Indirect
Participants, as defined below, and by Participants and Indirect Participants
to Beneficial Owners will be governed by arrangements among them, subject to
any statutory or regulatory requirements as may be in effect from time to
time.

If (x) the Depository is at any time unwilling or unable to continue as
Depository and a successor depository is not appointed by the Company within
60 days, (y) the Company executes and delivers to the Trustee a

S-13
<PAGE>

Company Order to the effect that the Global Securities shall be exchangeable
or (z) an Event of Default has occurred and is continuing with respect to the
Securities, the Global Securities will be exchangeable for Securities in
definitive form of like tenor and of an equal aggregate principal amount, in
denominations of $10 and integral multiples thereof. Such definitive
Securities shall be registered in such name or names as the Depository shall
instruct the Trustee. It is expected that such instructions may be based upon
directions received by the Depository from Participants with respect to
ownership of beneficial interests in such Global Securities.

The following is based on information furnished by DTC:

DTC will act as securities depository for the Securities. The Securities
will be issued as fully registered securities registered in the name of Cede &
Co. (DTC's partnership nominee). One or more fully registered Global Security
will be issued for the Securities in the aggregate principal amount of such
issue, and will be deposited with DTC.

DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law,
a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934, as amended. DTC holds securities that its Participants
deposit with DTC. DTC also facilitates the settlement among Participants of
securities transactions, such as transfers and pledges, in deposited
securities through electronic computerized book-entry changes in Participants'
accounts, thereby eliminating the need for physical movement of securities
certificates. Direct Participants of DTC ("Direct Participants") include
securities brokers and dealers, banks, trust companies, clearing corporations
and certain other organizations. DTC is owned by a number of its Direct
Participants and by The New York Stock Exchange, Inc., the American Stock
Exchange, Inc., and the National Association of Securities Dealers, Inc.
Access to the DTC's system is also available to others such as securities
brokers and dealers, banks and trust companies that clear through or maintain
a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to DTC and its
Participants are on file with the SEC.

Purchases of Securities under the DTC's system must be made by or through
Direct Participants, which will receive a credit for the Securities on the
DTC's records. The ownership interest of each Beneficial Owner is in turn to
be recorded on the records of Direct Participants and Indirect Participants.
Beneficial Owners will not receive written confirmation from DTC of their
purchase, but Beneficial Owners are expected to receive written confirmations
providing details of the transaction, as well as periodic statements of their
holdings, from the Direct Participants or Indirect Participants through which
such Beneficial Owner entered into the transaction. Transfers of ownership
interests in the Securities are to be accomplished by entries made on the
books of Participants acting on behalf of Beneficial Owners. Beneficial Owners
will not receive certificates representing their ownership interests in
Securities, except as provided above.

To facilitate subsequent transfers, all Securities deposited with DTC are
registered in the name of DTC's partnership nominee, Cede & Co. The deposit of
Securities with DTC and their registration in the name of Cede & Co. effect no
change in beneficial ownership. DTC has no knowledge of the actual Beneficial
Owners of the Securities; DTC's records reflect only the identity of the
Direct Participants to whose accounts such Securities are credited, which may
or may not be the Beneficial Owners. The Participants will remain responsible
for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed
by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. will consent or vote with respect to the
Securities. Under its usual procedures, DTC mails an Omnibus Proxy to the
Company as soon as possible after the applicable record date. The Omnibus
Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts the Securities are credited on the record date
(identified in a listing attached to the Omnibus Proxy).

S-14
<PAGE>

Principal, premium, if any, and/or interest, if any, payments on the
Securities will be made in immediately available funds to DTC. DTC's practice
is to credit Direct Participants' accounts on the applicable payment date in
accordance with their respective holdings shown on the Depository's records
unless DTC has reason to believe that it will not receive payment on such
date. Payments by Participants to Beneficial Owners will be governed by
standing instructions and customary practices, as is the case with securities
held for the accounts of customers in bearer form or registered in "street
name", and will be the responsibility of such Participant and not of DTC, the
Trustee or the Company, subject to any statutory or regulatory requirements as
may be in effect from time to time. Payment of principal, premium, if any,
and/or interest, if any, to DTC is the responsibility of the Company or the
Trustee, disbursement of such payments to Direct Participants shall be the
responsibility of DTC, and disbursement of such payments to the Beneficial
Owners shall be the responsibility of Direct Participants and Indirect
Participants.

DTC may discontinue providing its services as securities depository with
respect to the Securities at any time by giving reasonable notice to the
Company or Trustee. Under such circumstances, in the event that a successor
securities depository is not obtained, Security certificates are required to
be printed and delivered.

The Company may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository). In that event,
Security certificates will be printed and delivered.

SAME-DAY SETTLEMENT AND PAYMENT

Settlement for the Securities will be made by the Underwriter in immediately
available funds. All payments of principal and the Supplemental Redemption
Amount, if any, will be made by the Company in immediately available funds so
long as the Securities are maintained in book-entry form.

THE INDEX

GENERAL

Unless otherwise stated, all information herein on the Index is derived from
Dow Jones or other publicly available sources. Such information reflects the
policies of Dow Jones as stated in such sources and such policies are subject
to change by Dow Jones. Dow Jones is under no obligation to continue to
publish the Index and may discontinue publication of the Index at any time.

The Index is a price-weighted index (i.e., the weight of a component stock
in the Index is based on its price per share rather than the total market
capitalization of the issuer of such component stock) comprised of 30 common
stocks chosen by the editors of the WSJ as representative of the broad market
of U.S. industry. The corporations represented in the Index tend to be leaders
within their respective industries and their stocks are typically widely held
by individuals and institutional investors. Changes in the composition of the
Index are made entirely by the editors of the WSJ without consultation with
the corporations represented in the Index, any stock exchange, any official
agency or the Company. Changes to the common stocks included in the Index tend
to be made infrequently. Historically, most substitutions have been the result
of mergers, but from time to time, changes may be made to achieve what the
editors of the WSJ deem to be a more accurate representation of the broad
market of U.S. industry. In choosing a new corporation for the Index, the
editors of the WSJ look for leading industrial companies with a successful
history of growth and wide interest among investors. The component stocks of
the Index may be changed at any time for any reason. Dow Jones, publisher of
the WSJ, is not affiliated with the Company and has not participated in any
way in the creation of the Securities.

The Index initially consisted of 12 common stocks and was first published in
the WSJ in 1896. The Index was increased to include 20 common stocks in 1916
and to 30 common stocks in 1928. The number of common stocks in the Index has
remained at 30 since 1928, and, in an effort to maintain continuity, the
constituent corporations represented in the Index have been changed on a
relatively infrequent basis.

S-15
<PAGE>

The value of the Index is the sum of the primary exchange prices of each of
the 30 common stocks included in the Index, divided by a divisor that is
designed to provide a meaningful continuity in the value of the Index. Because
the Index is price-weighted, stock splits or changes in the component stocks
could result in distortions in the Index value. In order to prevent such
distortions related to extrinsic factors, the divisor is changed in accordance
with a mathematical formula that reflects adjusted proportions within the
Index. The current divisor of the Index is published daily in the WSJ and
other publications. In addition, other statistics based on the Index may be
found in a variety of publicly available sources.

The Company or its affiliates may presently or from time to time engage in
business with one or more of the issuers of the component stocks of the Index,
including extending loans to, or making equity investments in, such issuers or
providing advisory services to such issuers, including merger and acquisition
advisory services. In the course of such business, the Company or its
affiliates may acquire non-public information with respect to such issuers.
The Company does not make any representation to any purchaser of Securities
with respect to any matters whatsoever relating to such issuers. Any
prospective purchaser of Securities should undertake an independent
investigation of the issuers of the component stocks of the Index as in its
judgment is appropriate to make an informed decision with respect to an
investment in the Securities. The composition of the Index does not reflect
any investment or sell recommendations of the Company or its affiliates.

The following table presents the listing symbol, industry group, price per
share, total number of shares outstanding and market capitalization for each
of the component stocks in the Index based on publicly available information
as of November 28, 1997/1/.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

Set forth in full below is the opinion of Brown & Wood LLP, counsel to the
Company, as to certain United States Federal income tax consequences of the
purchase, ownership and disposition of the Securities. Such opinion is based
upon laws, regulations, rulings and decisions now in effect, all of which are
subject to change (including retroactive changes in effective dates) or
possible differing interpretations. The discussion below deals only with
Securities held as capital assets and does not purport to deal with persons in
special tax situations, such as financial institutions, insurance companies,
regulated investment companies, dealers in securities or currencies, tax-
exempt entities, persons holding Securities in a tax-deferred or tax-
advantaged account, or persons holding Securities as a hedge against currency
risks, as a position in a "straddle" or as part of a "hedging" or "conversion"
transaction for tax purposes. It also does not deal with holders other than
original purchasers (except where otherwise specifically noted herein). The
following discussion also assumes that the issue price of the Securities, as
determined for United States Federal income tax purposes, equals the principal
amount thereof. Persons considering the purchase of the Securities should
consult their own tax advisors concerning the application of the United States
Federal income tax laws to their particular situations as well as any
consequences of the purchase, ownership and disposition of the Securities
arising under the laws of any other taxing jurisdiction.

As used herein, the term "U.S. Holder" means a beneficial owner of a
Security that is for United States Federal income tax purposes (a) a citizen
or resident of the United States, (b) a corporation, partnership or other
entity created or organized in or under the laws of the United States or of
any political subdivision thereof (other than a partnership that is not
treated as a United States person under any applicable Treasury regulations),
(c) an estate the income of which is subject to United States Federal income
taxation regardless of its source, (d) a trust if a court within the United
States is able to exercise primary supervision over the administration of the
trust and one or more United States persons have the authority to control all
substantial decisions of the trust, or (e) any other person whose income or
gain in respect of a Security is effectively connected with the conduct of a
United States trade or business. Notwithstanding the preceding sentence, to
the extent provided in Treasury regulations, certain trusts in existence on
August 20, 1996, and treated as United States persons prior to such date that
elect to continue to be treated as United States persons also will be a U.S.
Holder. As used herein, the term "non-U.S. Holder" means a beneficial owner of
a Security that is not a U.S. Holder.

GENERAL

There are no statutory provisions, regulations, published rulings or
judicial decisions addressing or involving the characterization, for United
States Federal income tax purposes, of the Securities or securities with terms
substantially the same as the Securities. However, although the matter is not
free from doubt, under current law, each Security should be treated as a debt
instrument of the Company for United States Federal income tax purposes. The
Company currently intends to treat each Security as a debt instrument of the
Company for United States Federal income tax purposes and, where required,
intends to file information returns with the Internal Revenue Service ("IRS")
in accordance with such treatment, in the absence of any change or
clarification in the law, by regulation or otherwise, requiring a different
characterization of the Securities. Prospective investors in the Securities
should be aware, however, that the IRS is not bound by the Company's
characterization of the Securities as indebtedness and the IRS could possibly
take a different position as to the proper characterization of the Securities
for United States Federal income tax purposes. The following discussion of the
principal United States Federal income tax consequences of the purchase,
ownership and disposition of the Securities is based upon the assumption that
each Security will be treated as a debt instrument of the Company for United
States Federal income tax purposes. If the Securities are not in fact treated
as debt instruments of the Company for United States Federal income tax
purposes, then the United States Federal income tax treatment of the purchase,
ownership and disposition of the Securities could differ from the treatment
discussed below with the result that the timing and character of income, gain
or loss recognized in respect of a Security could differ from the timing

S-19
<PAGE>

and character of income, gain or loss recognized in respect of a Security had
the Securities in fact been treated as debt instruments of the Company for
United States Federal income tax purposes.

U.S. HOLDERS

On June 11, 1996, the Treasury Department issued final regulations (the
"Final Regulations") concerning the proper United States Federal income tax
treatment of contingent payment debt instruments such as the Securities, which
apply to debt instruments issued on or after August 13, 1996 and, accordingly,
will apply to the Securities. In general, the Final Regulations cause the
timing and character of income, gain or loss reported on a contingent payment
debt instrument to substantially differ from the timing and character of
income, gain or loss reported on a contingent payment debt instrument under
general principles of prior United States Federal income tax law.
Specifically, the Final Regulations generally require a U.S. Holder of such an
instrument to include future contingent and noncontingent interest payments in
income as such interest accrues based upon a projected payment schedule.
Moreover, in general, under the Final Regulations, any gain recognized by a
U.S. Holder on the sale, exchange, or retirement of a contingent payment debt
instrument is treated as ordinary income and all or a portion of any loss
realized could be treated as ordinary loss as opposed to capital loss
(depending upon the circumstances). The Final Regulations provide no
definitive guidance as to whether or not an instrument is properly
characterized as a debt instrument for United States Federal income tax
purposes.

In particular, solely for purposes of applying the Final Regulations to the
Securities, the Company has determined that the projected payment schedule for
the Securities will consist of payment on the maturity date of the principal
amount thereof and a projected Supplemental Redemption Amount equal to $3.6070
per Unit (the "Projected Supplemental Redemption Amount"). This represents an
estimated yield on the Securities equal to 6.18% per annum (compounded
semiannually). Accordingly, during the term of the Securities, a U.S. Holder
of a Security will be required to include in income as ordinary interest an
amount equal to the sum of the daily portions of interest on the Security that
are deemed to accrue at this estimated yield for each day during the taxable
year (or portion of the taxable year) on which the U.S. Holder holds such
Security. The amount of interest that will be deemed to accrue in any accrual
period (i.e., generally each six month period during which the Securities are
outstanding) will equal the product of this estimated yield (properly adjusted
for the length of the accrual period) and the Security's adjusted issue price
(as defined below) at the beginning of the accrual period. The daily portions
of interest will be determined by allocating to each day in the accrual period
the ratable portion of the interest that is deemed to accrue during the
accrual period. In general, for these purposes, a Security's adjusted issue
price will equal the Security's issue price (i.e., $10), increased by the
interest previously accrued on the Security. At maturity of a Security, in the
event that the actual Supplemental Redemption Amount, if any, exceeds $3.6070
per Unit (i.e., the Projected Supplemental Redemption Amount), a U.S. Holder
will be required to include the excess of the actual Supplemental Redemption
Amount over $3.6070 per Unit (i.e., the Projected Supplemental Redemption
Amount) in income as ordinary interest on the maturity date. Alternatively, in
the event that the actual Supplemental Redemption Amount, if any, is less than
$3.6070 per Unit (i.e., the Projected Supplemental Redemption Amount), the
excess of $3.6070 per Unit (i.e., the Projected Supplemental Redemption
Amount) over the actual Supplemental Redemption Amount will be treated first
as an offset to any interest otherwise includible in income by the U.S. Holder
with respect to the Security for the taxable year in which the maturity date
occurs to the extent of the amount of such includible interest. A U.S. Holder
will be permitted to recognize and deduct, as an ordinary loss that is not
subject to the limitations applicable to miscellaneous itemized deductions,
any remaining portion of the excess of $3.6070 per Unit (i.e., the Projected
Supplemental Redemption Amount) over the actual Supplemental Redemption Amount
that is not treated as an interest offset pursuant to the foregoing rules.
U.S. Holders purchasing a Security at a price that differs from the adjusted
issue price of the Security as of the purchase date (e.g., subsequent
purchasers) will be subject to special rules providing for certain adjustments
to the foregoing rules and such U.S. Holders should consult their own tax
advisors concerning these rules.

Upon the sale or exchange of a Security prior to the maturity date, a U.S.
Holder will be required to recognize taxable gain or loss in an amount equal
to the difference, if any, between the amount realized by the

S-20
<PAGE>

U.S. Holder upon such sale or exchange and the U.S. Holder's adjusted tax
basis in the Security as of the date of disposition. A U.S. Holder's adjusted
tax basis in a Security generally will equal such U.S. Holder's initial
investment in the Security increased by any interest previously included in
income with respect to the Security by the U.S. Holder. Any such taxable gain
will be treated as ordinary income. Any such taxable loss will be treated as
ordinary loss to the extent of the U.S. Holder's total interest inclusions on
the Security. Any remaining loss generally will be treated as long-term or
short-term capital loss (depending upon the U.S. Holder's holding period for
the Security). All amounts includible in income by a U.S. Holder as ordinary
interest pursuant to the Final Regulations will be treated as original issue
discount.

All prospective investors in the Securities should consult their own tax
advisors concerning the application of the Final Regulations to their
investment in the Securities. Investors in the Securities may also obtain the
projected payment schedule, as determined by the Company for purposes of the
application of the Final Regulations to the Securities, by submitting a
written request for such information to Merrill Lynch & Co., Inc., Attn:
Darryl W. Colletti, Corporate Secretary's Office, 100 Church Street, 12th
Floor, New York, New York 10080-6512.

The projected payment schedule (including both the Projected Supplemental
Redemption Amount and the estimated yield on the Securities) has been
determined solely for United States Federal income tax purposes (i.e., for
purposes of applying the Final Regulations to the Securities), and is neither
a prediction nor a guarantee of what the actual Supplemental Redemption Amount
will be, or that the actual Supplemental Redemption Amount will even exceed
zero.

The following table sets forth the amount of interest that will be deemed to
have accrued with respect to each Unit of the Securities during each accrual
period over a term of five years and twenty-two days for the Securities based
upon the projected payment schedule for the Securities as determined by the
Company for purposes of applying the Final Regulations to the Securities:

NON-U.S. HOLDERS

A non-U.S. Holder will not be subject to United States Federal income taxes
on payments of principal, premium (if any) or interest (including original
issue discount, if any) on a Security, unless such non-U.S. Holder is a direct
or indirect 10% or greater shareholder of the Company, a controlled foreign
corporation related to the

S-21
<PAGE>

Company or a bank receiving interest described in section 881(c)(3)(A) of the
Internal Revenue Code of 1986, as amended. However, income allocable to non-
U.S. Holders will generally be subject to annual tax reporting on IRS Form
1042S. For a non-U.S. Holder to qualify for the exemption from taxation, the
last United States payor in the chain of payment prior to payment to a non-
U.S. Holder (the "Withholding Agent") must have received in the year in which
a payment of interest or principal occurs, or in either of the two preceding
calendar years, a statement that (a) is signed by the beneficial owner of the
Security under penalties of perjury, (b) certifies that such owner is not a
U.S. Holder and (c) provides the name and address of the beneficial owner. The
statement may be made on an IRS Form W-8 or a substantially similar form, and
the beneficial owner must inform the Withholding Agent of any change in the
information on the statement within 30 days of such change. If a Security is
held through a securities clearing organization or certain other financial
institutions, the organization or institution may provide a signed statement
to the Withholding Agent. However, in such case, the signed statement must be
accompanied by a copy of the IRS Form W-8 or the substitute form provided by
the beneficial owner to the organization or institution.

Under current law, a Security will not be includible in the estate of a non-
U.S. Holder unless the individual is a direct or indirect 10% or greater
shareholder of the Company or, at the time of such individual's death,
payments in respect of such Security would have been effectively connected
with the conduct by such individual of a trade or business in the United
States.

BACKUP WITHHOLDING

Backup withholding of United States Federal income tax at a rate of 31% may
apply to payments made in respect of the Securities to registered owners who
are not "exempt recipients" and who fail to provide certain identifying
information (such as the registered owner's taxpayer identification number) in
the required manner. Generally, individuals are not exempt recipients, whereas
corporations and certain other entities generally are exempt recipients.
Payments made in respect of the Securities to a U.S. Holder must be reported
to the IRS, unless the U.S. Holder is an exempt recipient or establishes an
exemption. Compliance with the identification procedures described in the
preceding section would establish an exemption from backup withholding for
those non-U.S. Holders who are not exempt recipients.

In addition, upon the sale of a Security to (or through) a broker, the
broker must withhold 31% of the entire purchase price, unless either (a) the
broker determines that the seller is a corporation or other exempt recipient
or (b) the seller provides, in the required manner, certain identifying
information and, in the case of a non-U.S. Holder, certifies that such seller
is a non-U.S. Holder (and certain other conditions are met). Such a sale must
also be reported by the broker to the IRS, unless either (a) the broker
determines that the seller is an exempt recipient or (b) the seller certifies
its non-U.S. status (and certain other conditions are met). Certification of
the registered owner's non-U.S. status would be made normally on an IRS Form
W-8 under penalties of perjury, although in certain cases it may be possible
to submit other documentary evidence.

Any amounts withheld under the backup withholding rules from a payment to a
beneficial owner would be allowed as a refund or a credit against such
beneficial owner's United States Federal income tax provided the required
information is furnished to the IRS.

NEW WITHHOLDING REGULATIONS

On October 6, 1997, the Treasury Department issued new regulations (the "New
Regulations") which make certain modifications to the backup withholding and
information reporting rules described above. The New Regulations will
generally be effective for payments made after December 31, 1998, subject to
certain transition rules. Prospective investors are urged to consult their own
tax advisors regarding the New Regulations.

S-22

USE OF PROCEEDS

The net proceeds from the sale of the Securities will be used as described
under "Use of Proceeds" in the attached Prospectus and to hedge market risks
of the Company associated with its obligation to pay the Principal Amount and
the Supplemental Redemption Amount.

UNDERWRITING

Merrill Lynch, Pierce, Fenner & Smith Incorporated (the "Underwriter") has
agreed, subject to the terms and conditions of the Underwriting Agreement and
a Terms Agreement, to purchase from the Company $90,000,000 aggregate
principal amount of Securities. The Underwriting Agreement provides that the
obligations of the Underwriter are subject to certain conditions precedent and
that the Underwriter will be obligated to purchase all of the Securities if
any are purchased.

The Underwriter has advised the Company that it proposes initially to offer
all or part of the Securities directly to the public at the offering prices
set forth on the cover page of this Prospectus Supplement. After the initial
public offering, the public offering price may be changed. The Underwriter is
offering the Securities subject to receipt and acceptance and subject to the
Underwriter's right to reject any order in whole or in part.

The underwriting of the Securities will conform to the requirements set
forth in the applicable sections of Rule 2720 of the Conduct Rules of the
National Association of Securities Dealers, Inc.

The Underwriter is permitted to engage in certain transactions that
stabilize the price of the Securities. Such transactions consist of bids or
purchases for the purpose of pegging, fixing or maintaining the price of the
Securities.

If the Underwriter creates a short position in the Securities in connection
with the offering, i.e., if it sells more Units of the Securities than are set
forth on the cover page of this Prospectus Supplement, the Underwriter may
reduce that short position by purchasing Units of the Securities in the open
market.

In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher
than it might be in the absence of such purchases.

Neither the Company nor the Underwriter makes any representation or
prediction as to the direction or magnitude of any effect that the
transactions described above may have on the price of the Securities. In
addition, neither the Company nor the Underwriter makes any representation
that the Underwriter will engage in such transactions or that such
transactions, once commenced, will not be discontinued without notice.

The Underwriter may use this Prospectus Supplement and the accompanying
Prospectus for offers and sales related to market-making transactions in the
Securities. The Underwriter may act as principal or agent in these
transactions, and the sales will be made at prices related to prevailing
market prices at the time of sale.

VALIDITY OF SECURITIES

The validity of the Securities will be passed upon for the Company and for
the Underwriter by Brown & Wood LLP, New York, New York.
