PROSPECTUS SUPPLEMENT
(TO PROSPECTUS DATED OCTOBER 14, 1993)

                              1,000,000 WARRANTS
                           PAINE WEBBER GROUP INC.
                       Japan Export Index Put Warrants
                          Expiring October    , 1997

                           ------------------------
 
     Each Warrant will entitle the holder thereof to receive from Paine Webber
Group Inc. (the 'Company'), upon exercise (including automatic exercise), an
amount in U.S. dollars calculated by reference to decreases in the Japan
Export Index (the 'Index'). Such amount (the 'Cash Settlement Value') will
equal the product, if positive, of        multiplied by the quotient (rounded
down to the nearest cent) of (A) the Index Strike Price minus the Index Spot
Price for the applicable Valuation Date (as defined herein), divided by (B) a
fixed Japanese yen/U.S. dollar exchange rate of yen    per U.S.$1.00. If the
Index Spot Price for such Valuation Date equals or exceeds the Index Strike
Price, the Cash Settlement Value will be zero; in which case, the
Warrantholder will be permitted, subject to certain exceptions, to re-exercise
such Warrant prior to the Expiration Date or the Delisting Date (as defined
herein). The Index Strike Price will equal the closing value of the Index in
Tokyo on the date the Warrants are priced for the initial offering to the
public and the Index Spot Price will be determined upon exercise as more fully
described herein.
 
     The Warrants are unsecured contractual obligations of the Company and
will rank on a parity with the Company's other unsecured contractual
obligations and with the Company's unsecured and unsubordinated debt.
 
     THE WARRANTS INVOLVE A HIGH DEGREE OF RISK, INCLUDING THE RISK OF
EXPIRING WORTHLESS IF THE LEVEL OF THE INDEX DOES NOT DECREASE DURING THE
PERIOD WHEN THE WARRANTS MAY BE EXERCISED. PURCHASERS SHOULD BE PREPARED TO
SUSTAIN A TOTAL LOSS OF THE PURCHASE PRICE OF THEIR WARRANTS AND ARE ADVISED
TO CONSIDER CAREFULLY THE INFORMATION UNDER 'RISK FACTORS RELATING TO THE
WARRANTS' BEGINNING ON PAGE S-10 AND 'RISK FACTORS' BEGINNING ON PAGE 3 IN THE
ACCOMPANYING PROSPECTUS, AS WELL AS THE OTHER INFORMATION HEREIN AND IN THE
ACCOMPANYING PROSPECTUS.
 
     The Warrants have been approved for listing on the Chicago Board Options
Exchange, Inc. (the 'CBOE'), subject to official notice of issuance. The CBOE
symbol for the Warrants is JXP.WS.

Securities Offered
  Price.................   Japan Export Index Put Warrants Expiring October   ,
                           1997 (the 'Warrants'). Each Warrant will entitle the
                           holder thereof to receive from the Company, upon
                           exercise (including automatic exercise), an amount in
                           U.S. dollars calculated by reference to decreases in
                           the Japan Export Index (the 'Index'). Such amount
                           (the 'Cash Settlement Value') will equal the product,
                           if positive, of multiplied by the quotient (rounded
                           down to the nearest cent) of (A) the amount, if any,
                           by which the Index Strike Price (as hereinafter
                           defined) exceeds the Index Spot Price for the
                           applicable Valuation Date (as hereinafter defined),
                           divided by (B) a fixed Japanese yen/U.S. dollar
                           exchange rate of yen   per U.S.$1.00. This amount is
                           described by the following formula:
 
                                             CASH SETTLEMENT VALUE =
                          _______  X  (INDEX STRIKE PRICE - INDEX SPOT PRICE)/
                                         (FIXED YEN /U.S.$ EXCHANGE RATE)


                           If the Index Spot Price for a Valuation Date is equal
                           to or exceeds the Index Strike Price, the
                           corresponding Cash Settlement Value will equal zero;
                           in which case, the Warrantholder will be permitted,
                           subject to certain exceptions, to re-exercise such

                           Warrant prior to the Expiration Date or the Delisting
                           Date (as hereinafter defined). The Index Strike Price
                           will be the Closing Index Value on the date the
                           Warrants are priced by the Company for initial
                           offering to the public. The Index Spot Price is the
                           Closing Index Value on the Valuation Date relating to
                           an Exercise Date. The Closing Index Value for any
                           Index Calculation Day is the closing value of the
                           Index on such date.
Price...................   U.S.$  per Warrant.

The Japan Export
  Index.................   The Japan Export Index (the 'Index') is a stock index
                           designed by Nomura Securities International, Inc.
                           ('NSI') and calculated, published and disseminated by
                           the Chicago Board Options Exchange, Inc. (the
                           'CBOE'), in its sole discretion. NSI will not
                           calculate, publish, disseminate or maintain the
                           Index, and is not responsible for the calculation of
                           the Cash Settlement Amount or any other amounts
                           required to be calculated in connection with the
                           Warrants. The Index is being used by the Company with
                           the permission of the CBOE. The Index measures the
                           composite price performance of selected stocks
                           (currently of 40 companies) trading on the First
                           Section of the Tokyo Stock Exchange (the 'TSE'),
                           which represent certain of the largest Japanese
                           export companies, as measured by yen-denominated
                           export revenue. The Index was first calculated and
                           published by CBOE on September 22, 1995.
                           Stocks that comprise the Index may be changed or
                           substituted by the CBOE based on certain criteria.
                           The CBOE is under no obligation to continue the
                           calculation or the dissemination of the Index. See
                           'The Japan Export Index' herein. If the CBOE
                           discontinues publication of the Index, the
                           Determination Agent (as hereinafter defined) shall
                           determine the applicable Cash Settlement Value based
                           on the formula and method used in calculating the
                           Index as in effect on the date the Index was last
                           published. See 'Risk Factors Relating to the
                           Warrants' herein.
Exercise of Warrants....   The Warrants will be exercisable immediately upon
                           issuance (subject to postponement as described herein
                           under 'Description of the Warrants--Extraordinary
                           Events and Exercise Limitation Events') and may be
                           exercised until 3:00 P.M., New York City time, on the

                           Limitation Events.' Any Warrant not exercised at or
                           before the Expiration Date or any Delisting Date will
                           be automatically exercised on such date; provided,

                           disruption events, suspensions and trading halts.
                           Prospective purchasers of the Warrants should
                           recognize that their Warrants may expire worthless.
                           Investors should be prepared to sustain a total loss
                           of the purchase price of the Warrant. The Warrants
                           are appropriate investments only for investors with
                           options approved accounts who are able to understand
                           and bear the risk of a speculative investment in the
                           Warrants.
                           The Underlying Stocks that constitute the Index have
                           been issued by Japanese companies. Investments in
                           securities indexed to the value of Japanese equity
                           securities involve certain risks associated with the
                           Japanese securities markets, including the risks of
                           volatility in such markets, government intervention
                           in such markets, cross-shareholdings in Japanese
                           companies, a lack of public information about
                           Japanese companies and accounting and financial
                           standards that differ from those applicable to
                           certain U.S. companies.
                           Securities prices in Japan, and the prices of the
                           stocks of Japanese export companies in particular,
                           are subject to political, economic, financial and
                           social factors that apply in Japan. Stock prices of
                           Japanese export companies are also affected by
                           factors involving the countries in which those
                           companies' principal trading partners do business.
                           These factors could negatively affect the Japanese
                           securities markets generally and the price of the
                           stocks of Japanese export companies in particular.
                           Moreover, the Japanese economy may differ favorably
                           or unfavorably from the U.S. economy in such respects
                           as growth of gross national product, rate of
                           inflation, capital reinvestment, resources and
                           self-sufficiency.
                           It is not possible to predict how the Warrants will
                           trade in the secondary market or whether such market
                           will be liquid or illiquid. To the extent Warrants
                           are exercised, the number of Warrants outstanding
                           will decrease, resulting in a decrease in the
                           liquidity of the Warrants. In addition, the Company
                           or one or more of its affiliates or the Underwriters
                           may from time to time purchase Warrants resulting in
                           a decrease in the liquidity of the Warrants. The
                           trading value of a Warrant is expected to be
                           dependent upon the Index Strike Price and also upon a

                           number of complex interrelated factors, including the
                           value of the Index, the volatility of the Index,

                           the time remaining to the expiration of the Warrants,
                           the dividend rate on the stocks underlying the Index,
                           Japan yen/U.S. dollar exchange rates and interest
                           rates in Japan and the United States.
                           In the event the Warrants are delisted from, or
                           permanently suspended from trading on, the CBOE and
                           not accepted at the same time trading pursuant to the
                           rules of another United States national securities
                           exchange, Warrants not previously exercised will be
                           deemed automatically exercised on the Delisting Date,
                           and the Cash Settlement Value, if any, shall be
                           calculated and settled as provided below under
                           'Description of the Warrants--Delisting of Warrants.'
                           Potential investors should be aware that PaineWebber,
                           in its capacity as Determination Agent, is under no
                           obligation to take the interests of the Company or
                           the Warrantholders into consideration in the event it
                           determines, composes or calculates the Cash
                           Settlement Value. However, PaineWebber is an
                           affiliate of the Company, and certain conflicts of
                           interest may arise in connection with PaineWebber
                           performing its role as Determination Agent.
                           PaineWebber, 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 Warrants to restrict the use of information
                           relating to the calculation of the Cash Settlement
                           Value prior to its dissemination. Moreover,
                           PaineWebber is obligated to carry out its duties and
                           functions as Determination Agent in good faith and
                           using its reasonable judgment. See 'Description of
                           the Warrants--Exercise and Settlement of Warrants.'
                           Except in the event of automatic exercise, a
                           Warrantholder must tender at least 500 Warrants at
                           any one time in order to exercise his Warrants. Thus,
                           except in such an event, holders of Warrants with
                           fewer than 500 Warrants will need either to sell
                           their Warrants or to purchase additional Warrants,
                           incurring transaction costs in each case, in order to
                           realize upon their investment.
                           A Warrantholder will not be able to determine, at the
                           time of exercise of a Warrant, the Index Spot Price
                           that will be used in calculating the Cash Settlement

                           Value of such Warrant (and thus will be unable to
                           determine such Cash Settlement Value). In addition,
                           the Valuation Date for exercised Warrants may be
                           postponed upon the occurrence and continuation of an
                           Extraordinary Event or an Exercise Limitation Event
                           (see 'Description of the Warrants--Extraordinary
                           Events and Exercise Limitation Events' herein) or as
                           a result of the exercise of a number of Warrants
                           exceeding the limits on exercise described below
                           under 'Description of the Warrants--Maximum Exercise

                           Index between the time a Warrantholder submits an
                           Exercise Notice and the time the Index Spot Price for
                           such exercise is determined (which period will, at a
                           minimum, represent an entire Tokyo Business Day (as
                           hereinafter defined) and, in the case of a Valuation

                           of a postponement resulting from the exercise of a
                           number of Warrants exceeding the limits on exercise

                           such Warrantholder receiving a Cash Settlement Value
                           or Alternative Settlement Amount (as hereinafter
                           defined) (including a zero Alternative Settlement
                           Amount) that is less than the Cash Settlement Value
                           anticipated by such Warrantholder based on the level
                           of the Index most recently reported prior to
                           exercise, subject to the Limit Option described below

                           The CBOE will calculate the Index once each Index
                           Calculation Day (as hereinafter defined) based upon
                           the most recent official closing prices of each of
                           the Underlying Stocks as reported by the TSE. Due to
                           time differences, trading on the TSE occurs when the
                           CBOE is closed for business.
                           If the Company determines that on a Valuation Date an
                           Extraordinary Event or Exercise Limitation Event has
                           occurred and is continuing, then the Cash Settlement
                           Value or Alternative Settlement Amount may be
                           calculated on a later date than the date otherwise
                           provided herein.
                           INVESTORS ARE ADVISED TO CONSIDER CAREFULLY THE
                           FOREGOING RISK FACTORS AND THE RISKS AND OTHER
                           MATTERS DISCUSSED UNDER 'RISK FACTORS' IN THE
                           PROSPECTUS AND 'RISK FACTORS RELATING TO THE

                           HEREIN PRIOR TO PURCHASING THE WARRANTS.
Who Should Invest.......   The CBOE requires that the Warrants be sold only to
                           investors whose accounts have been approved for
                           options trading, and further requires that its
                           members and member organizations and registered
                           employees thereof make certain suitability
                           determinations before recommending transactions in
                           the Warrants. As indicated above, investors should be
                           prepared to sustain a total loss of the purchase
                           price of the Warrants.
                           Investors who are considering purchasing the Warrants
                           should be able to understand and bear the risk of a
                           speculative investment in the Warrants, be
                           experienced with respect to options and option
                           transactions and understand the risks of
                           international stock index transactions. Such
                           investors should reach an investment decision only
                           after careful consideration with their advisers of
                           the suitability of the Warrants in light of their
                           particular financial circumstances and the
                           information set forth in this Prospectus Supplement

     A substantial portion of the proceeds to be received by the Company from
the sale of the Warrants will be used by the Company, one or more of its

purchasing or maintaining positions in a variety of financial instruments
relating to the Index, the Underlying Stocks and the Japanese yen/U.S. dollar
exchange rate (which may include certain types of instruments that entail only
potential payments upon closeout but not up-front acquisition costs). The
conduct of such hedging activities will not be limited to any particular
securities or futures exchange. Depending on the actual number of Warrants
outstanding from time to time, among other matters, the aggregate amount and the
composition of such positions are likely to vary over time. The remainder of the
proceeds, if any, will be used for general corporate purposes.

                     RISK FACTORS RELATING TO THE WARRANTS
 
GENERAL MARKET AND TIMING RISKS
 
     General. The registered or beneficial owner of a Warrant (a
'Warrantholder') will receive a cash payment from the Company upon exercise
(including automatic exercise) only if such Warrant has a Cash Settlement Value
(or, if applicable, upon the occurrence of an Extraordinary Event or any
Exercise Limitation Event as described under 'Description of the
Warrants--Extraordinary Events and Exercise Limitation Events' herein, an
Alternative Settlement Amount, as hereinafter defined) greater than zero at such
time. The Warrants will be 'in-the-money' on the relevant Valuation Date only
if, as of such date, the value of the Index decreases so that the Index Spot
Price is below the Index Strike Price. A decrease in the level of the Index from
the date of this Prospectus Supplement will result in a greater Cash Settlement
Value for the Warrants and an increase in the level of the Index from the date
of this Prospectus Supplement will result in a lesser or zero Cash Settlement
Value for the Warrants. If a Warrant is not exercised prior to its expiration
and, on the Valuation Date with respect to its expiration, the value of the
Index is greater than or equal to the Index Strike Price, the Warrant will
expire worthless and the beneficial owner will have sustained a total loss of
the purchase price of such Warrant. Investors therefore should be prepared to
sustain a total loss of the purchase price of their Warrants.
 
     Time Lag After Exercise Instructions Given. Except under the circumstances
described below, the Valuation Date for an exercised Warrant will be the first
Index Calculation Day after the related Exercise Date. The Exercise Date for an
exercised Warrant, subject to certain exceptions described under 'Exercise and
Settlement of Warrants,' 'Limit Option' and 'Automatic Exercise' under
'Description of the Warrants' herein, will be the New York Business Day on which
such Warrant and an Exercise Notice (as hereinafter defined) in proper form are
received by the Warrant Agent (as hereinafter defined) if received at or prior
to 3:00 P.M., New York City time, on such day; if such Warrant and Exercise
Notice are received after such time, the Exercise Date will be the next
succeeding New York Business Day. See 'Description of the Warrants--Exercise and
Settlement of Warrants' herein. The Valuation Date for an exercised Warrant will
occur after the Exercise Date (see 'Description of the Warrants--Exercise and
Settlement of Warrants' herein). Therefore, a Warrantholder will not be able to
determine, at the time of exercise of a Warrant, the Index Spot Price that will
be used in calculating the Cash Settlement Value of such Warrant (and will thus
be unable to determine such Cash Settlement Value). In addition, the Valuation
Date for exercised Warrants may be postponed upon the occurrence and
continuation of an Extraordinary Event or an Exercise Limitation Event (see
'Description of the Warrants--Extraordinary Events and Exercise Limitation
Events' herein) or as a result of the exercise of a number of Warrants exceeding
the limits on exercise described below under 'Description of the
Warrants--Maximum Exercise Amount.' The value of the Index may change
significantly during any such period and such movements could adversely affect
the cash settlement value of the warrants being exercised.

 
RISKS ASSOCIATED WITH INTERNATIONAL STOCK INDEX WARRANTS
 
     Investment decisions relating to international stock index warrants require
the investor to predict the direction of movements in the underlying index as
well as the amount and timing of those movements. International stock index
warrants may change substantially in value, or lose all of their value, with
relatively small movements in the underlying index. Moreover, an international
stock index warrant is a 'wasting asset' in that, in the absence of
countervailing factors, such as an offsetting movement in the level of the
index, the market value of an index warrant will tend to decrease over time and
the warrant will have no market value after the time for exercise has expired.
Accordingly, international stock index warrants involve a high degree of risk
and are not appropriate for every investor. Investors who are considering
purchasing the Warrants must be able to understand and bear the risk of a
speculative investment in the Warrants and be experienced with respect to
options and option transactions and understand the risks of stock indexes. Such
investors should reach an investment decision only after careful consideration
with their advisors of the suitability of the Warrants in light of their
particular financial circumstances and the information set forth in this
Prospectus Supplement and in the Prospectus.
 
UNDERLYING STOCKS
 
     General. The Underlying Stocks that constitute the Index have been issued
by Japanese companies. Investments in securities indexed to the value of
Japanese equity securities involve certain risks. The Japanese securities
markets may be more volatile than United States or other securities markets and
may be affected by market developments in different ways than United States or
other securities markets. Direct or indirect
 
                                      S-10
<PAGE>
government intervention to stabilize the Japanese securities markets and
cross-shareholdings in Japanese companies may affect prices and volume of
trading of Japanese equity securities.
 
     Public information regarding the issuers of the Underlying Stocks may be
obtained through the TSE. In certain instances, the Underlying Stocks are traded
in the United States in the form of American Depositary Receipts ('ADRs') and
public information concerning issuers of such ADRs may be obtained through the
SEC and any relevant exchange or quotation system. However, prospective
investors in the Warrants should be aware that there is generally less publicly
available information about Japanese companies than about United States
companies that are subject to the reporting requirements of the SEC. Also,
Japanese companies are subject to accounting, auditing and financial reporting
standards and requirements that differ from those to which United States
reporting companies are subject. Accordingly, information regarding the issuers
of the Underlying Stocks may be limited in comparison to information regarding
United States corporate issuers whose securities are publicly traded in the
United States.
 
     Underlying Stocks Traded Primarily on the TSE. The Underlying Stocks are
listed on the First Section of the TSE. The TSE has adopted certain measures

intended to prevent any extreme short-term price fluctuation resulting from
order imbalances. These include daily price floors and ceilings intended to
prevent extreme fluctuations in individual stock prices. Any stock listed on the
TSE cannot be traded at a price outside of these limits which are stated in
absolute Japanese yen limits, and not percentage limits, from the closing price
of the stock on the previous day. In addition, when there is a major order
imbalance in a listed stock, the TSE posts a 'special bid quote' or a 'special
asked quote' for that stock at a specified higher or lower price level than the
stock's last sale price in order to solicit counter orders and balance supply
and demand for the stock. Investors should also be aware that the TSE may
suspend the trading of individual stocks in certain limited and extraordinary
circumstances including, for example, unusual trading activity in that stock. As
a result, variations in the Index may be limited by price limitations on, or by
suspension of trading in, individual stocks which comprise the Index which may,
in turn, adversely affect the value of the Warrants. See 'Description of the
Warrants' herein.
 
IMPORTANT CONSIDERATIONS RELATING TO JAPAN AND JAPANESE EXPORT COMPANIES
 
     Securities prices in Japan are subject to political, economic, financial
and social factors that apply in Japan. Stock prices of Japanese export
companies are also affected by factors involving the countries in which those
companies' principal trading partners do business. These factors (including the
possibility that recent or future changes in the Japanese government's economic
and fiscal policies, the possible imposition of, or changes in, currency
exchange laws or other Japanese laws or restrictions applicable to Japanese
companies or investments in Japanese equity securities and the possibility of
fluctuations in the rate of exchange between currencies) could negatively affect
the Japanese securities markets generally and the prices of the stocks of
Japanese export companies particularly. Moreover, the Japanese economy may
differ favorably or unfavorably from the United States economy in such respects
as growth of gross national product, rate of inflation, capital reinvestment,
resources and self-sufficiency.
 
     The Index is comprised of Japanese companies that derive a significant
portion of their revenues from exports. The value of the stocks comprising the
Index is, therefore, subject to fluctuation as a result of foreign and domestic
economic and political factors affecting the ability of Japanese companies to
provide goods and services for export, including, without limitation, the value
of the Japanese yen in comparison to the value of the currencies of its
principal trading partners and restrictions on trade established by Japan's
trading partners or by Japanese authorities.
 
OFFERING PRICE OF WARRANTS; WARRANTS NOT A PERFECT HEDGE
 
     The initial public offering price of the Warrants is in excess of the price
a commercial user of or dealer in options on the Index might pay for comparable
options involving significantly larger amounts. The Warrants should not be
considered to be a perfect hedge with respect to the value of the Japan Export
Index or all or any portion of the Underlying Stocks.
 
CERTAIN FACTORS AFFECTING THE VALUE OF THE WARRANTS
 
     The Cash Settlement Value of the Warrants at any time prior to expiration

is typically expected to be less than the Warrants' trading value at that time.
The difference between the trading value and the Cash Settlement Value will
reflect a number of factors, including a 'time value' for the Warrants. The
'time value' of the Warrants will depend upon the length of the period remaining
to expiration, among other factors. The expiration date of the Warrants will be
accelerated should the Warrants be delisted or should their trading on the CBOE
be suspended permanently unless the
 
                                      S-11
<PAGE>
Warrants simultaneously are accepted for trading pursuant to the rules of
another United States national securities exchange. Any such acceleration would
result in the total loss of any otherwise remaining time value, and could occur
when the Warrants are out-of-the-money, thus resulting in total loss of the
purchase price of the Warrants. See 'Description of the Warrants.' Before
exercising or selling Warrants, Warrantholders should carefully consider the
trading value of the Warrants, the value of the Index at the time, the time
remaining to expiration and the probable range of Cash Settlement Values and any
related transaction costs.
 
     It is possible that the trading value of a Warrant may decline even if
there is a decrease in the value of
the Index.
 
     Investors should be aware that this is the first listing of an equity index
warrant on the CBOE and that warrants relating to the Index have not been
publicly offered in the United States and there can be no assurance as to how
the Warrants will trade in the secondary market or whether such market will be
liquid. The trading value of a Warrant is expected to be dependent upon the
value of the Index Strike Price and also upon a number of complex interrelated
factors, including those listed below. The expected theoretical effect on the
trading value of a Warrant of each of the factors listed below, assuming in each
case that all other factors are held constant, is as follows:
 
          (1) The Index.  If the value of the Index increases, the trading value
     of a Warrant is expected to decrease. If the value of the Index decreases,
     the trading value of a Warrant is expected to increase.
 
          (2) The volatility of the Index.  If the volatility of the Index
     increases, the trading value of a Warrant is expected to increase. If the
     volatility of the Index decreases, the trading value of a Warrant is
     expected to decrease.
 
          (3) Interest rates in Japan and the United States.  In general, if
     United States interest rates increase, the trading value of the Warrants is
     expected to decrease. If United States interest rates decrease, the trading
     value of the Warrants is expected to increase. If interest rates in Japan
     increase, the trading value of a Warrant is expected to decrease. If
     interest rates in Japan decrease, the trading value of a Warrant is
     expected to increase. Changes in Japanese interest rates may affect the
     economy of Japan and, in turn, the Index, and the trading value of the
     Warrants.
 
          (4) Dividend rates in Japan.  If dividend rates on the Underlying

     Stocks increase, the trading value of a Warrant is expected to increase. If
     dividend rates on the Underlying Stocks decrease, the trading value of a
     Warrant is expected to decrease. Changes in the dividend rates on the
     Underlying Stocks may directly affect the value of the Index and therefore
     the value of the Warrants as described above.
 
          (5) Japanese yen/U.S. dollar exchange rates.  The Cash Settlement
     Value is based on a given level of the Index and will not be affected by
     changes in the Japanese yen/U.S. dollar exchange rate. However, a number of
     economic factors, including the Japanese yen/U.S. dollar exchange rate,
     could affect the value of the Underlying Stocks and, therefore, the value
     of the Index.
 
As noted above, these hypothetical scenarios are based on the assumption that
all other factors are held constant. In reality, it is unlikely that only one
factor would change in isolation, because changes in one factor usually cause or
result from changes in others. Some of the factors referred to above are, in
turn, influenced by the political and economic factors discussed above. No
assurances can be given that the expected theoretical effects on the trading
value of the Warrants described above will prove to be accurate.
 
MINIMUM EXERCISE AMOUNT
 
     Except for cases of automatic exercise, a Warrantholder must tender at
least 500 Warrants at any one time in order to exercise Warrants. Thus, except
in cases of automatic exercise, Warrantholders with fewer than 500 Warrants must
either sell their Warrants or purchase additional Warrants, incurring
transaction costs in either case, in order to realize proceeds from their
investment. At any time that a Warrantholder must purchase additional Warrants
in order to have the minimum number of Warrants necessary to elect to exercise,
such Warrantholder will be subject to the secondary market for Warrants at the
time of any such purchase, including the risk that there may be a limited number
of the Warrants available in such market at such time and the other factors
affecting the secondary market discussed above. Furthermore, such Warrantholders
incur the risk that there may be differences between the trading value of the
Warrants and the Cash Settlement Value of such Warrants.
 
                                      S-12
<PAGE>
RISKS AND COSTS ASSOCIATED WITH CONVERSION AND EXERCISE OF WARRANTS
 
     The Warrants will be issued as certificates in registered form.
Warrantholders cannot, however, hold certificated positions through CEDEL or
Euroclear (as such terms are hereinafter defined). Accordingly, a beneficial
owner of Warrants holding such Warrants indirectly (for instance, through a
broker that holds such Warrants in 'street' name) may exercise such Warrants
only through such owner's registered holder. In the case of a beneficial owner
holding Warrants through his broker in 'street' name, such beneficial owner must
direct his broker, who may in turn need to direct another intermediary, to
deliver an Exercise Notice (as hereinafter defined) and the related Warrants to
the Warrant Agent (as hereinafter defined). To ensure that an Exercise Notice
and the related Warrants will be delivered to the Warrant Agent before 3:00
P.M., New York City time, on a given New York Business Day, a Warrantholder may
need to give exercise instructions to his broker or other intermediary

substantially earlier than 3:00 P.M., New York City time, on such day. Different
brokerage firms may have different cut-off times for accepting and implementing
exercise instructions from their customers. Therefore, Warrantholders should
consult with their brokers or other intermediaries, if applicable, as to
applicable cut-off times and other exercise mechanics. See 'Description of the
Warrants--Exercise and Settlement of Warrants' and '--Limit Option' herein.
 
     Forty-five calendar days after the closing of the offering (which closing
is expected to be on October   , 1995), each Warrantholder will have the option
to convert the form in which such Warrantholder holds his Warrants from
certificated to book-entry form (the 'Conversion Option'). Such conversion will
occur only through the facilities of The Depository Trust Company, New York, New
York ('DTC,' which term, as used herein and in the Prospectus, includes any
successor depositary selected by the Company). See 'Description of the
Warrants--Book-Entry Conversion' herein and 'Description of the
Warrants--Book-Entry Procedures and Settlement' in the Prospectus. To exercise
Warrants, a Warrantholder who has utilized the Conversion Option must direct a
broker, who may, in turn, need to direct a participating organization in DTC (a
'Participant'), to transfer Warrants held by DTC on behalf of such Warrantholder
and to submit an Exercise Notice to the Warrant Agent. A Warrantholder may
desire that the New York Business Day on which his Warrants and an Exercise
Notice are delivered on his behalf to the Warrant Agent will constitute the
Exercise Date for the Warrants being exercised (for example, to utilize the
Limit Option most effectively). To achieve such objective, a Warrantholder
holding Warrants in book-entry form must cause such Warrants to be transferred
free on the records of DTC to, and such Exercise Notice to be received by, the
Warrant Agent at or prior to 3:00 P.M., New York City time, on such New York
Business Day; provided, however, that in the case of Warrants in book-entry form
held through CEDEL or Euroclear, the Warrants must be transferred to the Warrant
Agent prior to 3:00 P.M., New York City time, on the applicable Valuation Date.
To ensure that such Warrants and Exercise Notice will be received by the Warrant
Agent at or prior to such time, such Warrantholder must give the appropriate
direction to his broker before such broker's (and, if such broker is not a
Participant, the applicable Participant's) cut-off time for accepting exercise
instructions from customers for that day. Different brokerage firms may have
different cut-off times for accepting and implementing exercise instructions
from their customers. Therefore, Warrantholders holding their Warrants in
book-entry form should consult with their brokers or other intermediaries, if
applicable, as to applicable cut-off times and other exercise mechanics. Under
no circumstances may Warrants in certificated form be exercised through the
facilities of CEDEL or Euroclear. The Company has been informed by CEDEL and
Euroclear that such clearing agencies will only clear, and facilitate exercises
of, Warrants in book-entry form. See 'Description of the Warrants--Exercise and
Settlement of Warrants,' '--CEDEL and Euroclear' and
'--Limit Option' herein. Forms of Exercise Notice for Warrants held in
book-entry form may be obtained at the Warrant Agent's Office (as hereinafter
defined) during the Warrant Agent's normal business hours. See 'Description of
the Warrants--General' herein.
 
RISKS DUE TO DELAY OR POSTPONEMENT OF VALUATION OF WARRANTS
 
     Any upward movement in the level of the Index between the time a
Warrantholder submits an Exercise Notice and the time the Index Spot Price for
such exercise is determined (which period will, at a minimum, represent an

entire Tokyo Business Day and, in the case of a Valuation Date postponed
following an Extraordinary Event or an Exercise Limitation Event or as a result
of there being exercised a number of Warrants exceeding the maximum permissible
amount, may be substantially longer) will, subject to the Limit Option described
below and under 'Description of the Warrants--Limit Option' herein, result in
such Warrantholder receiving a Cash Settlement Value or Alternative Settlement
Amount (including a zero Alternative Settlement Amount) that is less than the
Cash Settlement Value anticipated by such Warrantholder based on the closing
level
 
                                      S-13
<PAGE>
of the Index most recently reported prior to exercise. The CBOE will calculate
the Index based upon the most recent official closing prices of each of the
Underlying Stocks as reported by the TSE. Due to time differences, trading on
the TSE occurs when the CBOE is closed for business.
 
     Except in the event of automatic exercise, a Warrantholder may be able to
limit to some extent the risk associated with any upward movement in the Index
between an Exercise Date and the applicable Valuation Date if such
Warrantholder, in connection with an exercise of Warrants, elects the Limit
Option. Pursuant to the Limit Option, Warrants tendered for exercise will not be
exercised if the Index Spot Price for the applicable Valuation Date has
increased by 15 or more points from the Index Spot Price for the applicable
Exercise Date. See 'Description of the Warrants--Limit Option' herein.
 
     If the Company determines that an Extraordinary Event or an Exercise
Limitation Event has occurred and is continuing on any day that would otherwise
be a Valuation Date for any exercised Warrant, then the Valuation Date for such
Warrant will be postponed to the next Index Calculation Day following the Tokyo
Business Day on which there is no Extraordinary Event or Exercise Limitation
Event; provided that if the postponed Valuation Date has not occurred on or
prior to the Expiration Date or the Delisting Date, the Warrantholders will
receive the Alternative Settlement Amount (as described below) in lieu of the
Cash Settlement Value; provided further that, in the case of an Extraordinary
Event, if the Company determines that such Extraordinary Event is expected to
continue and the Company notifies the Warrant Agent that it is cancelling the
Warrants, then the date on which such notice is given (whether or not such date
is a New York Business Day) will become the Valuation Date for such Warrant, in
which case such Warrantholder will receive, in lieu of the Cash Settlement Value
of such Warrant, the Alternative Settlement Amount thereof, which is equal to
the greater of (a) the average of the last sale prices, if available, of the
Warrants on the CBOE (or any successor United States national securities
exchange on which the Warrants are listed) on the 30 trading days preceding the
date on which such Extraordinary Event was declared and (b) an amount equal to
the sum of the Cash Settlement Value of the Warrants on such Valuation Date and
a ratable portion of the initial offering price of the Warrants, in each case
subject to certain exceptions and adjustments. The Cash Settlement Value or the
Alternative Settlement Amount of a Warrant determined as of any such postponed
Valuation Date may be substantially lower (including zero) than the otherwise
applicable Cash Settlement Value thereof. See 'Description of the
Warrants--Extraordinary Events and Exercise Limitation Events' herein, which
includes a description of events, circumstances or causes constituting
Extraordinary Events and Exercise Limitation Events.

 
RISKS ASSOCIATED WITH RE-BALANCING OF THE INDEX
 
     The Index will be re-balanced on the last trading day of March of each year
and in the event that more than 33 1/3% of the value of the Index is comprised
of five or fewer Underlying Stocks. In connection with the re-balancing of the
Index, the weightings of the Underlying Stocks will be adjusted so that each
Underlying Stock will not comprise more than 2.5% of the Index value. See 'The
Japan Export Index' herein. In the period immediately prior to a re-balancing of
the Index, the Index value may fluctuate in a manner that differs from the
performance of the Index immediately following a re-balancing. Such fluctuation
may result from the fact that in a re-balancing of the Index the weightings of
Underlying Stocks that have increased in value in the period prior to a
re-balancing will be reduced after a re-balancing of the Index and the
weightings of Underlying Stocks that have declined in value in periods prior to
a re-balancing will be increased after a re-balancing of the Index. Changes in
the weightings of the Underlying Stocks over time may significantly affect the
characteristics, behavior and value of the Index. Prospective investors should
understand that as a result of the re-balancing of the Index the performance of
the Index may change significantly over time and could adversely affect any Cash
Settlement Value or Alternative Settlement Amount of the Warrants.
 
RISKS DUE TO DELISTING OF WARRANTS
 
     The Warrants have been approved for listing on the CBOE, subject to
official notice of issuance. In the event the Warrants are delisted from, or
permanently suspended from trading on (within the meaning of the Exchange Act
and the rules and regulations thereunder), the CBOE and not accepted at the same
time for listing on another United States national securities exchange, Warrants
not previously exercised will be deemed automatically exercised on the Delisting
Date, and the Cash Settlement Value, if any, shall be calculated and settled as
provided under 'Description of the Warrants--Delisting of Warrants' herein. In
the event of a delisting or suspension of trading on the CBOE, the Company will
use its best efforts to list the Warrants on another United States national
securities exchange.
 
                                      S-14
<PAGE>
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     Certain of the Underwriters and their affiliates may from time to time
engage in transactions involving the Underlying Stocks for their proprietary
accounts and for other accounts under their management, which may influence the
value of such Underlying Stocks and therefore the value of the Warrants. The
Company, or its subsidiaries or third parties, including the Underwriters or
their affiliates, may also be the writers of one or more hedges of the Company's
obligations under the Warrants and will be obligated to pay to the Company upon
exercise of Warrants an amount equal to the value of the exercised Warrants.
Under certain circumstances, conflicts of interest may arise between
PaineWebber's responsibilities as Determination Agent with respect to the
Warrants and its status as a subsidiary of the Company and with respect to its
duties as Determination Agent and its status as a writer of a hedge of the
issuer of the Warrants.
 

OTHER CONSIDERATIONS
 
     Options and warrants provide opportunities for investment and pose risks to
investors as a result of fluctuations in the value of the underlying investment.
In general, certain of the risks associated with the Warrants are similar to
those generally applicable to other options or warrants of private corporate
issuers. However, unlike options or warrants on equities or debt securities,
which are traded primarily on the basis of the value of a single underlying
security, the trading value of a Warrant is likely to reflect primarily the
value of the Index.
 
     The purchaser of a Warrant may lose his entire investment. This risk
reflects the nature of a Warrant as an asset which tends to decline in value
over time and which may, depending on the relative value of the Index, be
worthless when it expires. Assuming all other factors are held constant, the
more a Warrant is out-of-the-money and the shorter its remaining term to
expiration, the greater the risk that a purchaser of the Warrant will lose all
of his investment. This means that the purchaser of a Warrant who does not sell
it in the secondary market or exercise it prior to expiration will necessarily
lose his entire investment in the Warrant if it expires when the Index Spot
Price is greater than or equal to, the Index Strike Price.
 
     It is not possible to predict how the Warrants will trade in the secondary
market or whether such market will be liquid or illiquid. To the extent Warrants
are exercised, the number of Warrants outstanding will decrease, resulting in a
decrease in the liquidity of the Warrants. In addition, during the life of the
Warrants, the Company or one or more of its affiliates may from time to time
purchase and exercise the Warrants, resulting in a decrease in the liquidity of
the Warrants.
 
     The CBOE requires that the Warrants be sold only to investors whose
accounts have been approved for options trading. In addition, the CBOE requires
that its members and member organizations and registered employees thereof make
certain suitability determinations before recommending transactions in the
Warrants. Before making any investment in the Warrants, it is important that a
prospective investor become informed about and understand the nature of the
Warrants in general, the specific terms of the Warrants and the nature of the
relevant currency exchange rate. An investor should understand the consequences
of liquidating his investment in a Warrant by exercising it as opposed to
selling it. It is especially important for an investor to be familiar with the
procedures governing the exercise of Warrants, since a failure to properly
exercise a Warrant prior to its expiration could result in the loss of his
entire investment. This includes knowing when Warrants are exercisable and how
to exercise them.
 
     The fact that Warrants may become valueless upon expiration means that, in
order to recover and realize a return upon his investment, a purchaser of a
Warrant must generally be correct about the direction, timing and magnitude of
anticipated changes in the value of the Index. If the value of the Index does
not increase to an extent sufficient to cover an investor's cost of a Warrant
(i.e., the purchase price plus transaction costs, if any) before the Warrant
expires, the investor will lose all or a part of his investment in the Warrant
upon expiration. The Cash Settlement Value is based upon a given level of the
Index and will not be affected by changes in the Japanese yen/U.S. dollar

exchange rate. However, a number of economic factors, including the Japanese
yen/U.S. dollar exchange rate, could affect the value of the Underlying Stocks
and, therefore, the value of the Index.
 
     INVESTORS ARE ADVISED TO CONSIDER CAREFULLY THE FOREGOING RISK FACTORS AND
THE RISKS AND OTHER MATTERS DISCUSSED UNDER 'RISK FACTORS' IN THE PROSPECTUS AND
'CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS CONCERNING THE
WARRANTS' HEREIN, AS WELL AS THE OTHER INFORMATION IN THE PROSPECTUS AND HEREIN,
PRIOR TO PURCHASING THE WARRANTS.

                             THE JAPAN EXPORT INDEX
 
     Unless otherwise stated, all information herein regarding the Index is
derived from the CBOE or publicly available sources. Such information reflects
the policies of the CBOE as provided by such sources and such policies are
subject to change by the CBOE.
 
     The Japan Export Index (the 'Index') is a new stock index initially
comprised of 40 stocks of companies that are estimated to be the largest
Japanese export companies, as measured by total annual yen-denominated export
revenue during the last five (5) years, whose stocks are listed on the First
Section of the TSE and which have a stock market capitalization of greater than
100 billion Japanese yen, whose daily trading volume averaged over 100 million
Japanese yen per day over the last 250 trading days and whose export revenue as
a percentage of total revenues totalled more than 20% during the last five (5)
years (the 'Underlying Stocks').
 
     The Index was designed by NSI and is calculated, published and disseminated
by the CBOE, in its sole discretion. NSI will not calculate, publish,
disseminate or maintain the Index, and is not responsible for the calculation of
the Cash Settlement Value or any other amounts required to be calculated in
connection with the Warrants. The Index is calculated using an 'equal dollar
weighting' methodology so that at the time of the establishment of the initial
Index value and on an annual basis thereafter upon a 're-balancing' of the Index
on the last trading day of March of each year each of the component Underlying
Stocks comprising the Index will be equally represented and will comprise 2.5%
of the Index value. See 'Risk Factors Relating to the Warrants--Risks
Associated With Re-Balancing of the Index' herein. The value of the Index was
established at 100 as of March 31, 1984. The Index was last re-balanced on March
31, 1995. As of October   , 1995 the value of the Index was      . The Index
stocks are drawn from a broad base of industries. Business sector representation
of the Underlying Stocks comprising the Index as of the last re-balancing of the
Index was as follows: Autos and Auto Parts (25.0%) (10 Underlying Stocks);
Electric Machinery--diversified (22.5%) (9 Underlying Stocks); Consumer
Electronics (20.0%) (8 Underlying Stocks); Iron and Steel (7.5%) (3 Underlying
Stocks); Precision Instruments (7.5%) (3 Underlying Stocks); Shipbuilding (5.0%)
(2 Underlying Stocks); Chemicals (5.0%) (2 Underlying Stocks); Machinery (2.5%)
(1 Underlying Stock); Computers and Semiconductors (2.5%) (1 Underlying Stock);
and Services (2.5%) (1 Underlying Stock). (See Appendix B hereto for a list of
the Underlying Stocks as of October   , 1995.) The business sectors represented

by the Index are a result of the Underlying Stocks selected for inclusion in the
Index on the basis described above. Business sector representation is not a
factor in determining the composition of the Index. Accordingly, if the
Underlying Stocks are changed in the future, the business sectors represented by
the Index may differ significantly from those that are currently represented.
 
     In order to maintain the continuity in the Index in the event of certain
changes due to non-market factors affecting the Underlying Stocks, such as the
additions or deletion of stocks, substitution of stocks, stock dividends, stock
splits or distributions of assets to stockholders, the divisor used in
calculating the Index will be adjusted in a manner designed to prevent any
instantaneous change or discontinuity in the value of the Index and in order
that the value of the Index immediately after such change will equal the value
of the Index immediately prior to such change. Thereafter, the divisor will
remain the same until a further adjustment is necessary as the result of another
change, or until the next rebalancing date. Changes in the identities and
characteristics of the Underlying Stocks may significantly affect the behavior
of the Index over time.
 
     Underlying Stocks may be deleted or added by the CBOE in its sole
discretion. Any Underlying Stock deemed ineligible for listing in the First
Section of the TSE due to any of the following reasons will be deleted from the
Index: (i) bankruptcy of the issuer, (ii) merger of the issuer with, or
acquisition of the issuer by, another company, (iii) delisting of such stock,
(iv) transfer of such stock to the 'Seiri-post' because of excess debt of the
issuer or because of any other reason or (v) transfer of such stock to the
Second Section of the TSE. If a component security of the Index is removed, the
CBOE will, in its sole discretion, attempt to find a replacement security,
taking into account the factors for inclusion in the Index set forth above. The
CBOE intends that the Index will not fall below 35 component stocks. Subject to
the foregoing, Underlying Stocks may be deleted without contemporaneously
including a replacement security or added without contemporaneously deleting an
Underlying Stock. Additionally, the CBOE intends to monitor the weightings of
the component stocks of the Index and, if at any time five stocks account for
more than 33 1/3% of the total value of the Index, the CBOE will re-balance the
Index within the next 30 days.

     The total capitalization of the Underlying Stocks comprising the Index, as
of September 29, 1995, was approximately $545 billion, with the market
capitalization of the individual Underlying Stocks in the Index ranging from a
high of $70.67 billion to a low of $1.39 billion, and with a mean market
capitalization of $13.62 billion. On October   , 1995, no single stock accounted
for more than   % of the Index's total value, and the percentage weighting of
the five largest Underlying Stocks in the Index accounted for   % of the Index's
value.
 
     The Index is calculated once every Index Calculation Day by the CBOE based
on the most recent official closing prices of the Underlying Stocks reported by
the TSE. This closing value is disseminated prior to the opening of trading in
the United States through the options pricing reporting authority.
 
     The CBOE is under no obligation to continue the calculation and

dissemination of the Index. The Warrants are not sponsored, endorsed, sold or
promoted by the CBOE. No inference should be drawn from the information
contained in this Prospectus Supplement that the CBOE makes any representation
or warranty, implied or express, to the Company, the Warrantholders or any
member of the public regarding the advisability of investing in securities
generally or in the Warrants in particular or the ability of the Index to track
general stock market performance. The CBOE has no obligation to take the needs
of the Company or the Warrantholders into consideration in determining,
composing or calculating the Index. The CBOE is not responsible for, and has not
participated in the determination of, the timing of, prices for, or quantities
of, the Warrants to be issued or in the determination or calculation of the
equation by which the Warrants are to be settled in cash. The CBOE has no
obligation or liability in connection with the administration, marketing or
trading of the Warrants.
 
     None of the Company, the Warrant Agent, the Determination Agent or the
Underwriters accepts any responsibility for the calculation, maintenance or
publication of the Index. The CBOE disclaims all responsibility to the Company
for any errors or omissions in the calculation and dissemination of the Index or
the manner in which the Index is applied in determining any Cash Settlement
Value or Alternative Settlement Amount upon exercise of the Warrants.
 
HISTORICAL DATA ON THE INDEX
 
     The Index is a newly created index that the CBOE first calculated on
September 22, 1995. The following table sets forth the closing values calculated
by the CBOE for the Index each month in the period from March 31, 1984 through
September 29, 1995, assuming that the Underlying Stocks that presently comprise
the Index would have comprised the Index during the period. This data should not
be taken as an indication of the future performance of the Index.

THE TOKYO STOCK EXCHANGE
 
     The TSE is one of the world's largest securities exchanges in terms of
market capitalization. The TSE is a two-way, continuous pure auction market.
Trading hours are currently from 9:00 A.M. to 11:00 A.M. and from 12:30 P.M. to
3:00 P.M., Tokyo time, Monday through Friday.
 
     Due to the time zone difference, on any normal trading day the TSE will
close prior to the opening of business in New York City on the same calendar
day. Therefore, the closing level of the Index on such trading day will
generally be available in the United States by the opening of business on the
same calendar day.
 
     The TSE has adopted certain measures intended to prevent any extreme
short-term price fluctuations resulting from order imbalances. These include
daily price floors and ceilings intended to prevent extreme fluctuations in
individual stock prices. In general, any stocks listed on the TSE cannot be
traded at a price outside of these limits which are stated in absolute Japanese
yen, and not percentage, limits from the closing price of the stock on the
previous day. In addition, when there is a major order imbalance in a listed
stock, the TSE posts a 'special bid quote' or a 'special asked quote' for that
stock at a specified higher or lower price level than the stock's last sale
price in order to solicit counter orders and balance supply and demand for the
stock. Investors should also be aware that the TSE may suspend the trading of
individual stocks in certain limited and extraordinary circumstances including,
for example, unusual trading activity in that stock. As a result, variations in
the Index may be limited by price limitations, or by suspension of trading, on
individual stocks which comprise the Index which may, in turn, adversely affect
the value of the Warrants or result in an Exercise Limitation Event or
Extraordinary Event. See 'Description of the Warrants--Extraordinary Events and
Exercise Limitation Events' herein.

     The CBOE lists options on more than 700 stocks and on the two most actively

traded indices in the world, the S&P 100(Registered) (OEX(Registered)) and the
S&P 500(Registered) (SPX(Registered)), as well as on the Nasdaq 100
Index(Registered)(NDX(Registered)), the S&P SmallCap 600 Index, the Russell
2000(Registered) Index and thirteen sector indices. Options on the CBOE Mexico
Index (MEX), the Latin 15(Trademark) Index , the Nikkei 300 Index (NIK) and the
CBOE Israel Index (ISX) comprise the CBOE's foreign index option complex. The
CBOE also offers interest rate options; LEAPS(Registered), which are long-term
options on individual equities and stock indices; and FLEX(Trademark) (Flexible
Exchange(Trademark)) Options, an alternative to the over-the-counter options
market for institutional investors.

                          DESCRIPTION OF THE WARRANTS
 
GENERAL
 
     The Warrants will be issued pursuant to a Warrant Agreement (the 'Warrant
Agreement'), dated as of October   , 1995, between the Company, Citibank, N.A.,
as Warrant Agent (the Warrant Agent), and PaineWebber, as Determination Agent
(the 'Determination Agent'). The following summaries of certain provisions of
the Warrants and the Warrant Agreement do not purport to be complete and
reference is made to all the provisions of the Warrant Agreement (including the
form of Warrant Certificate and global Warrant certificate attached as exhibits
thereto). The Warrant Agreement will be available for inspection by any
Warrantholder at the office of the Warrant Agent (the 'Warrant Agent's Office')
which is currently located at 111 Wall Street, 5th Floor, New York, New York
10043, during the Warrant Agent's normal business hours. See 'Description of the
Warrants' in the Prospectus.
 
     The aggregate number of Warrants to be issued is set forth on the cover
page of this Prospectus Supplement and is subject to the right of the Company to
'reopen' the issue of Warrants and issue additional Warrants with substantially
identical terms at a later time. See 'Underwriting'.
 
     A Warrant will not require or entitle a Warrantholder to purchase or take
delivery of any Underlying Stocks or any other securities of the Company. Upon
exercise of a Warrant, the Company will make only a U.S. dollar cash payment in
the amount of the Cash Settlement Value or Alternative Settlement Amount, if any
and as applicable, of such Warrant. The Company is under no obligation to, nor
will it, sell or deliver to any Warrantholder shares of any of the Underlying
Stock or any other securities in connection with the exercise of any Warrants.
Warrantholders will not receive any interest on any Cash Settlement Value or
Alternative Settlement Amount and the Warrants will not entitle the
Warrantholders to any rights of holders of any Underlying Stock or any other
securities.
 
DETERMINATION OF CASH SETTLEMENT VALUE OF WARRANTS
 
     Each Warrant will entitle the Warrantholder to receive, upon exercise
(including automatic exercise), the Cash Settlement Value of such Warrant except
that, under the circumstances described under '--Extraordinary Events and
Exercise Limitation Events' below, such Warrantholder may instead receive the

Alternative Settlement Amount for such Warrant. The 'Cash Settlement Value' of a
Warrant will equal an amount in U.S. dollars equal to the product, if positive,
of ___ multiplied by the quotient (rounded down to the nearest cent) of (A) the
amount, if any, by which the Index Strike Price for the applicable Valuation
Date exceeds the Index Spot Price divided by (B) a fixed Japan yen/U.S. Dollar
exchange rate of yen          per U.S.$1.00. This amount is described by the
following formula:

 
  CASH SETTLEMENT VALUE =  _______  X  (INDEX STRIKE PRICE - INDEX SPOT PRICE)/
                      (FIXED YEN /U.S.$ EXCHANGE RATE)
 
     The 'Index Spot Price' relating to any Exercise Date will be determined by
Determination Agent and will equal the Closing Index Value (as calculated by the
CBOE) on the Valuation Date relating to such Exercise Date.
 
     The 'Index Strike Price' will equal the Closing Index Value on the date the
Warrants are priced by the Company for initial offering to the public.

HYPOTHETICAL WARRANT VALUES ON EXERCISE
 
     Set forth below is a hypothetical example demonstrating the Cash Settlement
Values of a Warrant at various levels of the Index. The hypothetical Cash
Settlement Values in the table do not reflect any 'time value' for a Warrant,
which may be reflected in trading value, and are not necessarily indicative of
potential profit or loss, which are also affected by purchase price and
transaction costs.

(1) Cash Settlement Values assume a hypothetical Index Strike Price of 200, a
    Japanese yen/U.S. dollar exchange rate of 100yen /$1.00 and a multiplier of
    17, all of which will be determined on the pricing date.
 
WARRANT CERTIFICATES
 
     The Warrants initially will be issued as certificates in registered form
(each, a 'Warrant Certificate'). The Warrant Agent will from time to time

register the transfer of any outstanding Warrant Certificate upon surrender
thereof at the Warrant Agent's Office duly endorsed by, or accompanied by a
written instrument or instruments of transfer in form satisfactory to the
Warrant Agent duly executed by, the registered holder thereof, a duly appointed
legal representative or a duly authorized attorney. Such signature must be
guaranteed by a bank or trust company having a correspondent office in New York
City or by a member of a United States national securities exchange. A new
Warrant Certificate will be issued to the transferee upon any such registration
of transfer.
 
     At the option of a Warrantholder, Warrant Certificates may be exchanged for
other Warrant Certificates representing an equal number of Warrants, upon
surrender to the Warrant Agent at the Warrant Agent's Office of the Warrant
Certificates to be exchanged. The Company will thereupon execute, and the
Warrant Agent will countersign and deliver, one or more new Warrant Certificates
representing such equal number of Warrants.
 
     In the event that, after any exercise of Warrants evidenced by a Warrant
Certificate, the number of Warrants exercised is fewer than the total number of
Warrants evidenced by such Certificate, a new Warrant Certificate evidencing the
number of Warrants not exercised will be issued to the registered holder or his
assignee. See '--Minimum Exercise Amount' below.
 
     If any Warrant Certificate is mutilated, lost, stolen or destroyed, the
Company may in its discretion execute, and the Warrant Agent may countersign and
deliver, in exchange and substitution for such mutilated Warrant Certificate, or
in replacement for such lost, stolen or destroyed Warrant Certificate, a new
Warrant Certificate representing an equal number of Warrants, but only (in the
case of loss, theft or destruction) upon receipt of evidence satisfactory to the
Company and the Warrant Agent of loss, theft or destruction of such Warrant
Certificate and security or indemnity, if requested, satisfactory to them.
Warrantholders requesting replacement Warrant Certificates must also comply with
such other reasonable regulations and pay such reasonable charges as the Company
or the Warrant Agent may prescribe. In the event that all the Warrants
represented by any such mutilated, lost, stolen or destroyed Warrant Certificate
have been or are about to be exercised (including upon automatic exercise), the
Company in its discretion may, instead of issuing a new Warrant Certificate,
direct the Warrant Agent to treat such Warrant Certificate as if the Warrant
Agent had received an Exercise Notice in proper form in respect thereof or as
being subject to automatic exercise, as the case may be.
 
     No service charge will be made for any registration of transfer or exchange
of Warrant Certificates, but the Company may require the payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
relation thereto, other than exchanges not involving any transfer. In the case
of the replacement of mutilated, lost, stolen or destroyed Warrant Certificates,
the Company may require the payment of a sum
 
                                      S-23

<PAGE>

sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the

Warrant Agent) connected therewith.
 
     Warrant Certificates held through CEDEL will be held by Citibank, N.A., New
York Office ('Citibank'), as custodian for CEDEL, and Warrant Certificates held
through Euroclear will be held by Morgan Guaranty Trust Company of New York, New
York Office ('Morgan'), as custodian for Euroclear. After the last day of the
Conversion Option Period, Warrantholders may no longer hold certificated
positions through CEDEL or Euroclear. See '--Book-Entry Conversion' herein.
 
BOOK-ENTRY CONVERSION
 
     Forty-five calendar days after the closing of the offering (which closing
date is expected to be October   , 1995), a Warrantholder will have the option
to convert the form in which such holder holds his Warrants from definitive to
book-entry form by utilizing the Conversion Option. The Conversion Option will
be available for forty-five calendar days (the 'Conversion Option Period') and
is expected to run from             , 1995, through             , 1995.
 
     In order to be exchanged for a Warrant in book-entry form, the Warrant
Certificate must be delivered to DTC, in proper form for deposit, by a
Participant. Accordingly, a Warrantholder who is not a Participant must deliver
his Warrant Certificate, in proper form for deposit, to a Participant, either
directly or through an indirect participant (such as a bank, brokerage firm,
dealer or trust company that clears through, or maintains a custodial
relationship with, a Participant) or a brokerage firm which maintains an account
with a Participant, in order to have its Warrant exchanged for a Warrant in
book-entry form. Warrantholders who desire to exchange their Warrant
Certificates for Warrants in book-entry form should contact their brokers or
other Participants or indirect participants to obtain information on procedures
for submitting their Warrant Certificates to DTC, including the proper form for
submission, and (during the Conversion Option Period) the cut-off times for same
day and next day exchange. Warrant Certificates which are held by a
Warrantholder in nominee or street name may be automatically exchanged into
book-entry form by the broker or other entity in whose name such Warrant
Certificates are registered, without action of, or consent by, the beneficial
owner of such Warrant. In addition, Warrant Certificates held through the
facilities of CEDEL or Euroclear will automatically be exchanged into book-entry
form by CEDEL or Euroclear, as the case may be, pursuant to the Conversion
Option on the last day of the Conversion Option Period without action of, or
consent by, the beneficial owner of the related Warrants. Under no circumstances
may Warrant Certificates be converted into Warrants in book-entry form through
the facilities of CEDEL or Euroclear.
 
     Warrant Certificates received by DTC for exchange during the Conversion
Option Period will be exchanged for Warrants in book-entry form by the close of
business on the New York Business Day that such Certificates are received by DTC
(if received by DTC at its then applicable cut-off time for same day credit) or
on the following New York Business Day (if received by DTC at its then
applicable cut-off time for next day credit). After the last day of the
Conversion Option Period, DTC will not be required to accept delivery of Warrant
Certificates in exchange for book-entry Warrants, but may permit Warrant
Certificates to be so exchanged on a case-by-case basis. However, there can be
no assurance that such Warrant Certificates would be accepted for exchange.
Warrants surrendered at any time for exchange for book-entry Warrants may not be

exercised or delivered for settlement of transfer until such exchange has been
effected. Accordingly, if a decrease in the value of the Index Spot Rate were to
occur after a Warrant Certificate had been surrendered for exchange into book-
entry form, a Warrantholder would not be able to take advantage of the decrease
by exercising his Warrant until such exchange had been effected. Because Warrant
Certificates are not required to be exchanged for Warrants in book-entry form,
it is likely that not all Warrant Certificates will be so exchanged.
Accordingly, Warrantholders purchasing Warrants in secondary market trading
after commencement of the Conversion Option Period may wish to make specific
arrangements with brokers or other Participants or indirect participants if they
wish to purchase Warrants only in book-entry form and not certificated form. The
Company has been informed by CEDEL and Euroclear that such clearing agencies
will only clear Warrants in book-entry form after the Conversion Option Period.
 
     Once a Warrantholder has elected the Conversion Option, such holder may
hold his Warrants only in book-entry form and will not be able to change his
election or withdraw from the book-entry system during the
 
                                      S-24

<PAGE>

Conversion Option Period or thereafter. Accordingly, except in certain limited
circumstances described in the Prospectus under 'Description of the
Warrants--Book-Entry Procedures and Settlement,' ownership of the Warrants in
certificated form will no longer be available to investors who have elected the
Conversion Option.
 
CEDEL AND EUROCLEAR
 
     Warrantholders may hold their Warrants only in book-entry form through
CEDEL or Euroclear if they are participants of such systems, or indirectly
through organizations which are participants in such systems. The common
security registration number used by CEDEL and Euroclear for the Warrants is
          . Certificated ownership of Warrants will not be available through
such systems.
 
     CEDEL and Euroclear will hold omnibus book-entry positions on behalf of
their participants through customers' securities accounts in CEDEL's and
Euroclear's names on the books of their respective depositaries which in turn
will hold such positions in customers' securities accounts in the names of the
nominees of the depositaries on the books of DTC. Citibank will act as
depositary for CEDEL and Morgan will act as depositary for Euroclear (in such
capacities, the 'Depositaries'). All securities in CEDEL or Euroclear are held
on a fungible basis without attribution of specific certificates to specific
securities clearance accounts.
 
     Exercises of book-entry Warrants by persons holding through CEDEL or
Euroclear participants will be effected through DTC, in accordance with DTC
rules, on behalf of the relevant European international clearing system by its
Depositary; however, such transactions will require delivery of exercise
instructions to the relevant European international clearing system by the
participant in such system in accordance with its rules and procedures and
within its established deadlines (European time). The relevant European

international clearing system will, if the exercise meets its requirements,
deliver instructions to its Depositary to take action to effect its exercise of
the Warrants on its behalf by delivering Warrants through DTC and receiving
payment in accordance with its normal procedures for next-day funds settlement.
Payments with respect to the Warrants held through CEDEL or Euroclear will be
credited to the cash accounts of CEDEL participants or Euroclear participants in
accordance with the relevant system's rules and procedures, to the extent
received by its Depositary. See '--Exercise and Settlement of Warrants' herein.
 
     Centrale de Livraison de Valeurs Mobilieres S.A. ('CEDEL') is incorporated
under the laws of Luxembourg as a professional depositary. CEDEL holds
securities for its participating organizations and facilitates the clearance and
settlement of securities transactions between CEDEL participants through
electronic book-entry changes in accounts of CEDEL participants, thereby
eliminating the need for physical movement of certificates. Transactions may be
settled through CEDEL in any of 28 currencies, including U.S. dollars. CEDEL
provides to its participants, among other things, services for safekeeping,
administration, clearance and settlement of internationally traded securities
and securities lending and borrowing. CEDEL interfaces with domestic markets in
several countries. As a professional depositary, CEDEL is subject to regulation
by the Luxembourg Monetary Institute. CEDEL participants are recognized
financial institutions around the world, including underwriters, securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations and may include the Underwriters (as hereinafter defined).
Indirect access to CEDEL is also available to others, such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a CEDEL participant, either directly or indirectly.
 
     The Euroclear System was created in 1968 to hold securities for
participants in the Euroclear System and to clear and settle transactions
between Euroclear participants through simultaneous electronic book-entry
delivery against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may now be settled in any of 30 currencies, including U.S.
dollars. The Euroclear System includes various other services, including
securities lending and borrowing and interfaces with domestic markets in several
countries generally similar to the arrangements for cross-market transfers with
DTC described above. The Euroclear System is operated by Morgan's Brussels,
Belgium office (the 'Euroclear Operator' or 'Euroclear'), under contract with
Euroclear Clearance System S.C., a Belgian cooperative corporation (the
'Cooperative'). Morgan is a member bank of the United States Federal Reserve
System. All operations are conducted by the Euroclear Operator, and all
Euroclear securities clearance accounts and Euroclear cash accounts are accounts
with the Euroclear Operator, not the Cooperative. The Cooperative establishes
policy for the Euroclear System on behalf of Euroclear participants. Euroclear
participants include
 
                                      S-25

<PAGE>

banks (including central banks), securities brokers and dealers and other
professional financial intermediaries and may include the Underwriters. Indirect
access to the Euroclear System is also available to other firms that clear

through or maintain a custodial relationship with a Euroclear participant,
either directly or indirectly.
 
     Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System, and applicable Belgian law
(collectively, the 'Terms and Conditions'). The Terms and Conditions govern
transfers of securities and cash within the Euroclear System, withdrawal of
securities and cash from the Euroclear System, and receipt of payments with
respect to securities in the Euroclear System. All securities in the Euroclear
System are held on a fungible basis without attribution of specific certificates
to specific securities clearance accounts. The Euroclear Operator acts under the
Terms and Conditions only on behalf of Euroclear participants, and has no record
of or relationship with persons holding through Euroclear participants.
 
     All information herein on CEDEL and Euroclear is derived from CEDEL or
Euroclear, as the case may be, and reflects the policies of such organizations;
such policies are subject to change without notice.
 
EXERCISE AND SETTLEMENT OF WARRANTS
 
     The Warrants will be immediately exercisable upon issuance subject to
postponement upon the occurrence of an Extraordinary Event or an Exercise
Limitation Event as described under '--Extraordinary Events and Exercise
Limitation Events' herein, and will expire on October   , 1997 (the 'Expiration
Date'). Warrants not exercised (including by reason of any such postponed
exercise) at or before 3:00 P.M., New York City time, on the earlier of (i) the
New York Business Day immediately preceding the Expiration Date and (ii) the
Delisting Date, will be automatically exercised as described under 'Automatic
Exercise' below. See '--Minimum Exercise Amount' and '--Maximum Exercise Amount'
below.
 
     A Warrantholder may exercise certificated Warrants on any New York Business
Day during the period from the date of issuance of such Warrants until 3:00
P.M., New York City time, on the earlier of (i) the New York Business Day
immediately preceding the Expiration Date and (ii) the Delisting Date, by
delivering or causing to be delivered to the Warrant Agent in New York City the
Warrant Certificate representing such Warrants with the irrevocable notice of
exercise on the reverse thereof (or a notice of exercise in substantially
identical form delivered therewith) (such notice, an 'Exercise Notice') duly
completed and executed. The Warrant Agent's telephone number and facsimile
transmission number for this purpose are (212) 657-7269 and (212) 825-3483,
respectively.
 
     In the case of book-entry Warrants held through the facilities of DTC, a
Warrantholder may exercise such Warrants on any New York Business Day during the
period from the date of issuance of such Warrants until 3:00 P.M., New York City
time, on the earlier of (i) the New York Business Day immediately preceding the
Expiration Date and (ii) the Delisting Date, by causing (x) such Warrants to be
transferred free to the Warrant Agent on the records of DTC and (y) a duly
completed and executed Exercise Notice to be delivered on behalf of the
Warrantholder by a Participant to the Warrant Agent. Forms of Exercise Notice
for Warrants held through the facilities of DTC may be obtained from the Warrant
Agent at the Warrant Agent's Office. The Warrant Agent's telephone number and

facsimile transmission number for this purpose are (201) 262-5444 and (201)
262-7521, respectively.
 
     In the case of book-entry Warrants held through the facilities of CEDEL or
Euroclear, a Warrantholder may exercise such Warrants on any New York Business
Day during the period from the date on which his certificated Warrants have been
effectively converted into book-entry form during the Conversion Option Period
(which will begin forty-five calendar days from the closing of the offering)
until 3:00 P.M., New York City time, on the earlier of (i) the New York Business
Day immediately preceding the Expiration Date and (ii) the Delisting Date, by
causing (x) such Warrants to be transferred free to the Warrant Agent by giving
appropriate instructions to the participant holding such Warrants in either the
CEDEL or Euroclear system, as the case may be, and (y) a duly completed and
executed Exercise Notice to be delivered on behalf of the Warrantholder by
CEDEL, in the case of Warrants held through CEDEL, or such participants, in the
case of Warrants held through Euroclear, to the Warrant Agent. Forms of Exercise
Notice for Warrants held through the facilities of either CEDEL or Euroclear may
be obtained from the Warrant Agent at the Warrant Agent's Office or from CEDEL
or Euroclear.

     Except for Warrants subject to automatic exercise or held in book-entry
form through the facilities of CEDEL or Euroclear, and subject to the Limit
Option, the 'Exercise Date' for a Warrant will be (i) the New York Business Day
on which the Warrant Agent receives the Warrant and Exercise Notice in proper
form with respect to such Warrant, if received at or prior to 3:00 P.M., New
York City time, on such day, or (ii) if the Warrant Agent receives such Warrant
and Exercise Notice after 3:00 P.M., New York City time, on a New York Business
Day, then the New York Business Day next succeeding such New York Business Day.
 
     In the case of Warrants held in book-entry form through the facilities of
CEDEL or Euroclear, except for Warrants subject to automatic exercise, and
subject to the Limit Option, the 'Exercise Date' for a Warrant will be (i) the
New York Business Day on which the Warrant Agent receives the Exercise Notice in
proper form with respect to such Warrant if such Exercise Notice is received at
or prior to 3:00 P.M., New York City time, on such day, provided that the
Warrant is received by the Warrant Agent by 3:00 P.M., New York City time, on
the Valuation Date, or (ii) if the Warrant Agent receives such Exercise Notice
after 3:00 P.M., New York City time, on a New York Business Day, then the New
York Business Day next succeeding such New York Business Day, provided that the
Warrant is received by 3:00 P.M., New York City time, on the Valuation Date
relating to exercises of Warrants on such succeeding New York Business Day. In
the event that the Warrant is received after 3:00 P.M., New York City time, on
the Valuation Date, then the Exercise Date for such Warrant will be the day on
which such Warrant is received or, if such day is not a New York Business Day,
the next succeeding New York Business Day. In the case of Warrants held through
the facilities of CEDEL or Euroclear, in order to ensure proper exercise on a
given New York Business Day, participants in CEDEL or Euroclear must submit
exercise instructions to CEDEL or Euroclear, as the case may be, by 10:00 A.M.,
Luxembourg time, in the case of CEDEL and by 10:00 A.M., Brussels time (by
telex), or 11:00 A.M., Brussels time (by EUCLID), in the case of Euroclear. In

addition, in the case of book-entry exercises by means of the Euroclear System,
(i) participants must also transmit, by facsimile (facsimile number (201)
262-7521), to the Warrant Agent a copy of the Exercise Notice submitted to
Euroclear by 3:00 P.M., New York City time, on the desired Exercise Date and
(ii) Euroclear must confirm by telex to the Warrant Agent by 9:00 A.M., New York
City time, on the Valuation Date that the Warrants will be received by the
Warrant Agent on such date; provided that if such telex communication is
received after 9:00 A.M., New York City time, on the Valuation Date, the Company
will be entitled to direct the Warrant Agent to reject the related Exercise
Notice or waive the requirement for timely delivery of such telex communication.
 
     To ensure that an Exercise Notice and the related Warrants will be
delivered to the Warrant Agent before 3:00 P.M., New York City time, on a given
New York Business Day, a Warrantholder may have to give exercise instructions to
his broker or other intermediary substantially earlier than 3:00 P.M., New York
City time, on such day. Different brokerage firms may have different cut-off
times for accepting and implementing exercise instructions from their customers.
Therefore, Warrantholders should consult with their brokers or other
intermediaries, if applicable, as to applicable cut-off times and other exercise
mechanics. See 'Risk Factors Relating to the Warrants--Risks and Costs
Associated with Conversion and Exercise of Warrants' above.
 
     Except in the case of Warrants subject to automatic exercise and for
Warrants that upon exercise will entitle the holder thereof to receive an
Alternative Settlement Amount in lieu of the Cash Settlement Amount, if on any
Valuation Date the Cash Settlement Value for any Warrants then exercised would
be zero, then the attempted exercise of such Warrants will be void and of no
effect and, in the case of certificated Warrants, the Warrant Certificate
evidencing such Warrants will be returned to the registered holder by first
class mail at the Company's expense or, in the case of Warrants held through the
facilities of DTC, CEDEL or Euroclear, such Warrants will be transferred back to
the Participant (including the Depositaries) that submitted them free on the
records of DTC, CEDEL or Euroclear, as the case may be, and, in any such case,
such Warrantholder will be permitted to re-exercise such Warrants prior to the
Expiration Date or the Delisting Date, as the case may be.
 
     The 'Valuation Date' for a Warrant will be the first Index Calculation Day
following the applicable Exercise Date, subject to postponement upon the
occurrence of an Extraordinary Event or an Exercise Limitation Event as
described below under '--Extraordinary Events and Exercise Limitation Events' or
as a result of the exercise of a number of Warrants exceeding the limits on
exercise described below under '--Maximum Exercise Amount.' The CBOE will
calculate the Index once each Index Calculation Day based upon the most recent
official closing prices of the Underlying Stocks as reported on the TSE. 'Index
Calculation Day' means any day on which the TSE is open for trading and the
Index is calculated and published. Due to time differences, trading
 
                                      S-27
<PAGE>
on the TSE occurs when the CBOE is closed for business. The following is an
illustration of the timing of an Exercise Date, the ensuing Valuation Date and
the Limit Option Reference Rate (as hereinafter defined), assuming (i) all
relevant dates are New York Business Days and Index Calculation Days, (ii) the
absence of any intervening Extraordinary Event or Exercise Limitation Event and

(iii) the number of exercised Warrants does not exceed the maximum permissible
amount. If the Warrant Agent receives a Warrantholder's Warrants and Exercise
Notice in proper form at or prior to 3:00 P.M., New York City time, on
           , October   , 1995, the Exercise Date for such Warrants will be
           , October   , 1995, and the Valuation Date for such Warrants will be
           , October   , 1995 (except that in the case of Warrants held through
the facilities of CEDEL or Euroclear, the Warrants must be received by 3:00
P.M., New York City time, on the Valuation Date; if such Warrants are received
after such time, then the Exercise Date for such Warrants will be the day on
which such Warrants are received or, if such day is not a New York Business Day,
the next succeeding New York Business Day, and the Valuation Date for such
Warrants will be the first New York Business Day following such Exercise Date
and the Limit Option Reference Rate will be the Index Spot Price on such
Exercise Date). The Index Spot Price used to determine the Cash Settlement Value
of such Warrants will be the closing level of the Index on            , October
  , 1995, which, because of time differences, will occur at 1:00 A.M., New York
City time, on      (or 2:00 A.M., New York City time, during the months in which
Eastern Daylight Savings Time is in effect). If the Warrantholder elected the
Limit Option in connection with the exercise of such Warrants, the Limit Option
Reference Rate would be the Index Spot Price on            , October   , 1995.
If the Warrant Agent were to receive such Warrantholder's Warrants and Exercise
Notice after 3:00 P.M., New York City time, on            , October   , 1995
(except that in the case of Warrants held through the facilities of CEDEL or
Euroclear, the Warrants must be received after 3:00 P.M., New York City time, on
           , October   , 1995), then the Exercise Date for such Warrants would
instead be            , October   , 1995, the Valuation Date would be
           , October   , 1995, and the applicable Limit Option Reference Rate
would be the Index Spot Price on            , October   , 1995.
 
     Following receipt of Warrants and the related Exercise Notice in proper
form, the Warrant Agent will, not later than 5:00 P.M., New York City time, on
the applicable Valuation Date (or, if the Valuation Date is not a New York
Business Day, on the next succeeding New York Business Day), (i) obtain the
Index Spot Price from the Determination Agent, (ii) determine the Cash
Settlement Value of such Warrants and (iii) advise the Company of the aggregate
Cash Settlement Value of the exercised Warrants. In the case of certificated
Warrants, if the Company has made adequate funds available to the Warrant Agent
in a timely manner as required by the Warrant Agreement, the Warrant Agent will
thereafter be responsible for making payment available to each registered holder
of a Warrant on the sixth New York Business Day following the Valuation Date in
the form of a cashier's check or official bank check, or (in the case of
payments of at least $100,000) by wire transfer to a U.S. dollar bank account
maintained by such holder in the United States (at such holder's election as
specified in the applicable Exercise Notice), in an amount equal to the
aggregate Cash Settlement Value of such holder's exercised Warrants. If the
Company has made such funds available by such time, the Warrant Agent will
thereafter be responsible for making funds available to each appropriate
Participant (including Citibank and Morgan, who, in turn, will disburse payments
to CEDEL and Euroclear, as the case may be, who will be responsible for
disbursing such payments to each of their respective participants, who, in turn,
will be responsible for disbursing payments to the Warrantholders they
represent), and such Participant will be responsible for disbursing such
payments to the Warrantholders it represents and to each brokerage firm for
which it acts as agent. Each such brokerage firm will be responsible for

disbursing funds to the Warrantholders that it represents.
 
     'Determination Agent' means PaineWebber or, in lieu thereof, another firm
selected by the Company to perform the functions of the Determination Agent in
connection with the Warrants. PaineWebber, in its capacity as Determination
Agent, will have no obligation to take the interests of the Company or the
Warrantholders into consideration in the event it determines, composes or
calculates the Cash Settlement Value. PaineWebber and its affiliates may from
time to time engage in transactions involving the Underlying Stocks for their
proprietary accounts and for other accounts under their management, which may
influence the value of such Underlying Stocks. Certain of the Underwriters and
their affiliates will also be the writers of the hedge of the Company's
obligations under the Warrants and will be obligated to pay to the Company upon
exercise of the Warrants an amount equal to the value of the Warrants.
Accordingly, under certain circumstances, conflicts of interest may arise
between PaineWebber's responsibilities as Determination Agent with respect to
the Warrants and its obligations under its hedge. In addition, because
PaineWebber is an affiliate of the Company, certain conflicts of
 
                                      S-28

<PAGE>

interest may arise in connection with PaineWebber performing its role as
Determination Agent. PaineWebber, 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 Warrants to restrict the use of information relating
to any calculation of the Cash Settlement Value prior to its dissemination.
PaineWebber is also obligated to carry out its duties and functions as
Determination Agent in good faith and using its reasonable judgment.
 
MINIMUM EXERCISE AMOUNT
 
     No fewer than 500 Warrants may be exercised by a Warrantholder at any one
time, except in the event of automatic exercise of the Warrants or exercise upon
cancellation of the Warrants as described under '--Extraordinary Events and
Exercise Limitation Events' below. Accordingly, except in the case of automatic
exercise of the Warrants or upon automatic cancellation of the Warrants,
Warrantholders with fewer than 500 Warrants will need either to sell their
Warrants or to purchase additional Warrants, thereby incurring transaction
costs, in order to realize upon their investment. Warrantholders must satisfy
the minimum exercise amount requirement described above separately with respect
to both certificated and book-entry Warrants even if both kinds of Warrants are
to be exercised at the same time. Thus, a Warrantholder seeking to exercise both
certificated and book-entry Warrants at the same time must still exercise a
minimum of 500 of each kind of Warrant in order to satisfy such requirement. In
addition, book-entry Warrants held through one Participant (including
participants in CEDEL or Euroclear) may not be combined with book-entry Warrants
held through another Participant in order to satisfy the minimum exercise
requirement.
 
MAXIMUM EXERCISE AMOUNT
 

     All exercises of Warrants (other than on the Expiration Date or the
Delisting Date or upon cancellation of the Warrants as described under
'--Extraordinary Events and Exercise Limitation Events' herein) are subject, at
the Company's option, to the limitation that not more than 1,000,000 Warrants in
total may be exercised on any Exercise Date and not more than 250,000 Warrants
may be exercised by or on behalf of any person or entity, either individually or
in concert with any other person or entity, on any Exercise Date. If any New
York Business Day would otherwise, under the terms of the Warrant Agreement, be
the Exercise Date in respect of more than 1,000,000 Warrants, then at the
Company's election 1,000,000 of such Warrants shall be deemed exercised on such
Exercise Date (selected by the Warrant Agent on a pro rata basis, but if, as a
result of such pro rata selection, any Warrantholder would be deemed to have
exercised fewer than 500 Warrants, then the Warrant Agent shall first select
additional Warrants of such holders so that no such holder shall be deemed to
have exercised fewer than 500 Warrants), and the remainder of such Warrants (the
'Remaining Warrants') shall be deemed exercised on the following New York
Business Day (subject to successive applications of this provision); provided
that any Remaining Warrant for which an Exercise Notice was delivered on a given
Exercise Date shall be deemed exercised before any other Warrants for which an
Exercise Notice was delivered on a later Exercise Date. If any individual
Warrantholder attempts to exercise more than 250,000 Warrants on any New York
Business Day, then at the Company's election 250,000 of such Warrants shall be
deemed exercised on such New York Business Day and the remainder shall be deemed
exercised on the following New York Business Day (subject to successive
applications of this provision). As a result of any postponed exercise as
described above, Warrantholders will receive a Cash Settlement Value determined
as of a date later than the otherwise applicable Valuation Date. In any such
case, as a result of any such postponement and subject to the Limit Option, the
Cash Settlement Value actually received by Warrantholders may be lower than the
otherwise applicable Cash Settlement Value if the Valuation Date of the Warrants
had not been postponed.
 
LIMIT OPTION
 
     Except for Warrants subject to automatic exercise, and except as described
below with respect to the payments of any Alternative Settlement Amount, each
Warrantholder, in connection with any exercise of Warrants (including a
postponed exercise following an Extraordinary Event or an Exercise Limitation
Event), will have the option (the 'Limit Option') to specify that such Warrants
are not to be exercised if the Index Spot Price that would otherwise be used to
determine the Cash Settlement Value of such Warrants is 15 or more points higher
than the closing level of the Index for the day specified (such rate, the 'Limit
Option Reference Rate'). A
 
                                      S-29
<PAGE>
Warrantholder's election of the Limit Option must be specified in the applicable
Exercise Notice delivered to the Warrant Agent. The Limit Option Reference Rate
will be the closing level of the Index on the relevant Exercise Date (or, if
such date is not an Index Calculation Day, on the immediately preceding Index
Calculation Day). If such Exercise Notice in proper form, together with the
related Warrants, is received by the Warrant Agent by 3:00 P.M., New York City
time, on a given day (which must be a New York Business Day), the Limit Option
Reference Rate will be the Index Spot Price for such day. If an Exercise Notice

and the related Warrants are received after 3:00 P.M., New York City time, on a
given day, the applicable Limit Option Reference Rate will be determined as of
the next day that is also a New York Business Day (or, if such day is not an
Index Calculation Day, on the immediately preceding Index Calculation Day).
 
     To ensure that the Limit Option will have its intended effect of limiting
the risk of any upward movement in the level of the Index between the date on
which a Warrantholder submits an Exercise Notice and the related Valuation Date,
such Exercise Notice and the related Warrants must be received by the Warrant
Agent not later than 3:00 P.M., New York City time, on the New York Business Day
on which they are submitted. See the illustration under '--Exercise and
Settlement of Warrants' above and 'Risk Factors Relating to the Warrants--Risks
Due to Delay or Postponement of Valuation of Warrants' herein.
 
     Following receipt of an Exercise Notice and the related Warrants subject to
the Limit Option, the Warrant Agent will obtain the applicable Limit Option
Reference Rate and will determine whether such Warrants will not be exercised
because of the Limit Option. Warrants that are not exercised will be treated as
not having been tendered for exercise, and either the Warrant Certificate
evidencing such Warrants will be returned to the registered holder by
first-class mail at the Company's expense or, in the case of Warrants held
through the facilities of DTC, CEDEL or Euroclear, such Warrants will be
transferred to the account at DTC, CEDEL or Euroclear, as the case may be, from
which they were transferred to the Warrant Agent. To exercise such Warrants, a
Warrantholder will be required to cause the Warrants and a related Exercise
Notice to be submitted again to the Warrant Agent.
 
     Once elected by a Warrantholder in connection with an exercise of Warrants,
the Limit Option will continue to apply, on the basis of the Limit Option
Reference Rate as initially determined for such Warrants, even if the Valuation
Date for such Warrants is postponed, except when such Valuation Date is
postponed until the Expiration Date, the Delisting Date or the Cancellation Date
(as hereinafter defined) as described under '--Extraordinary Events and Exercise
Limitation Events' below. Pursuant to the Limit Option, such Warrants will
either (i) be exercised on a delayed basis if the Index Spot Price on any
applicable postponed Valuation is not more than the Limit Option Reference Rate
by 15 or more points or (ii) be excluded from being exercised if, on any
applicable postponed Valuation Date, the Index Spot Rate is more than the Limit
Option Reference Rate by 15 or more points.
 
     In connection with any exercise of 500 or more Warrants, a Warrantholder
may elect to subject the exercise of only a portion of such Warrants to the
Limit Option, provided that the number of Warrants subject to the Limit Option
and the number of Warrants not subject to the Limit Option shall not in each
case be less than 500. A Warrantholder may not combine certificated and
book-entry Warrants in order to meet the 500-Warrant minimum requirement. See
'--Minimum Exercise Amount' above.
 
AUTOMATIC EXERCISE
 
     All Warrants for which the Warrant Agent has not received a valid Exercise
Notice at or prior to 3:00 P.M., New York City time, on the earlier of (i) the
New York Business Day immediately preceding the Expiration Date and (ii) the
Delisting Date, as the case may be, or for which the Warrant Agent has received

a valid Exercise Notice but with respect to which timely delivery of the
relevant Warrants has not been made, together with any Warrants the Valuation
Date for which has at such time been postponed as described under
'--Extraordinary Events and Exercise Limitation Events' below, will be
automatically exercised on such date; provided, however, that Warrants that have
no Cash Settlement Value will expire worthless. The Exercise Date for such
Warrants will be the Expiration Date or the Delisting Date, as the case may be,
or, if such Date is not a New York Business Day, the next succeeding New York
Business Day. The Warrant Agent will obtain the Index Spot Price (determined as
of the first Index Calculation Day following such day, which will be the
Valuation Day for such Warrants, except in the case of a postponed exercise
following the occurrence of an Extraordinary Event or, an
 
                                      S-30
<PAGE>
Exercise Limitation Event as described under '--Extraordinary Events and
Exercise Limitation Events' below) and will determine the Cash Settlement Value,
if any, of such Warrants.
 
     Except in the case of a postponed exercise following the occurrence of an
Extraordinary Event or an Exercise Limitation Event as described under
'--Extraordinary Events and Exercise Limitation Events' below, or in the case of
Warrants held through the facilities of DTC, CEDEL or Euroclear, if the Company
has made adequate funds available to the Warrant Agent in a timely manner as
required by the Warrant Agreement, the Warrant Agent will thereafter be
responsible for making a payment available to each registered holder of a
Warrant in the form of a cashier's check or official bank check, or (in the case
of payments of at least $100,000) by wire transfer to a U.S. dollar account
maintained by such holder in the United States (at such holder's election) after
3:00 P.M., New York City time, on the sixth New York Business Day after such
Valuation Date (or, if such Valuation Date is not a New York Business Day, on
the sixth New York Business Day following the New York Business Day next
succeeding such Valuation Date) against receipt by the Warrant Agent at the
Warrant Agent's Office of such holder's Warrant Certificates. Such payment will
be in an amount equal to the aggregate Cash Settlement Value of the Warrants
evidenced by such Warrant Certificates.
 
     In the case of book-entry Warrants subject to automatic exercise, and,
except in the case of a postponed exercise following the occurrence of an
Extraordinary Event or an Exercise Limitation Event described under
'--Extraordinary Events and Exercise Limitation Events' below, the Company will
be required to make available to the Warrant Agent, no later than 3:00 P.M., New
York City time, on the sixth New York Business Day after such Valuation Date
(or, if such Valuation Date is not a New York Business Day, on the sixth New
York Business Day following the New York Business Day next succeeding such
Valuation Date), funds in an amount sufficient to pay the aggregate Cash
Settlement Value of such Warrants. If the Company has made such funds available
by such time, the Warrant Agent will thereafter be responsible for making funds
available to DTC in an amount sufficient to pay the aggregate Cash Settlement
Value of the Warrants. DTC will be responsible for disbursing such funds to each
appropriate Participant (including Citibank and Morgan, who, in turn, will
disburse payments to CEDEL and Euroclear, as the case may be, who will be
responsible for disbursing such payments to each of their respective
participants, who, in turn, will be responsible for disbursing payments to the

Warrantholders they represent), and such Participant will be responsible for
disbursing such payments to the Warrantholders it represents and to each
brokerage firm for which it acts as agent. Each such brokerage firm will be
responsible for disbursing funds to the Warrantholders it represents.
 
EXTRAORDINARY EVENTS AND EXERCISE LIMITATION EVENTS
 
     Extraordinary Event.  The Warrant Agreement will provide that if the
Company determines that an Extraordinary Event has occurred and is continuing on
the Tokyo Business Day with respect to which the Index Spot Price on a Valuation
Date is to be determined (the 'Applicable Index Business Day'), then the Cash
Settlement Value in respect of an exercise shall be calculated on the basis that
the Valuation Date shall be the next Index Calculation Day following an
Applicable Index Business Day on which there is no Extraordinary Event or
Exercise Limitation Event; provided that if the Valuation Date has not occurred
on or prior to the Expiration Date or the Delisting Date, the Warrantholders
will receive the Alternative Settlement Amount in lieu of the Cash Settlement
Value which shall be calculated as if the Warrants had been cancelled on the
Expiration Date or the Delisting Date, as the case may be. The Company shall
promptly give notice to Warrantholders, by publication in a United States
newspaper with a national circulation (currently expected to be The Wall Street
Journal), if an Extraordinary Event shall have occurred.
 
     'Extraordinary Event' means any of the following events:
 
          (i) a suspension or absence of trading on the TSE of all the
     Underlying Stocks which then comprise the Index;
 
          (ii) the enactment, publication, decree or other promulgation of any
     statute, regulation, rule or order of any court or any United States or
     non-United States governmental or non-governmental authority which would
     make it unlawful for the Company to perform any of its obligations under
     the Warrant Agreement or the Warrants or to realize the benefits of the
     hedge of its position with respect to the Warrants; or
 
                                      S-31
<PAGE>
          (iii) any outbreak or escalation of hostilities or other national or
     international calamity or crisis (including, without limitation, natural
     calamities which in the opinion of the Company may materially and adversely
     affect the economy of Japan or the trading of securities generally on the
     TSE) which has or will have a material adverse effect on the ability of the
     Company to perform its obligations under the Warrants or to realize the
     benefits of the hedge of its position with respect to the Warrants.
 
     For the purpose of determining whether an Extraordinary Event has occurred:
(1) a limitation on the hours or number of days of trading on the TSE will not
constitute an Extraordinary Event if it results from an announced change in the
regular business hours of the TSE and (2) an 'absence of trading' on the TSE
will not include any time when the TSE itself is closed for trading under
ordinary circumstances.
 
     To the Company's knowledge, no circumstances have arisen since the
inception of the Index that could have constituted an Extraordinary Event and,

based on the information currently available to the Company, the Company is not
aware of any circumstance that would have constituted an Extraordinary Event
during the ten years prior to the inception of the Index, except that on January
7, 1989 trading was suspended on the TSE due to the death of the Emperor of
Japan (the '1989 Event'). The existence of such circumstances, however, is not
necessarily indicative of the likelihood of such circumstances arising or not
arising in the future. See 'The Japan Export Index--The Tokyo Stock Exchange'
below.
 
     If the Company determines that an Extraordinary Event has occurred and is
continuing, and if the Extraordinary Event is expected by the Company to
continue, the Company may immediately cancel the Warrants by notifying the
Warrant Agent of such cancellation (the date such notice is given being the
'Cancellation Date'), and each Warrantholder's rights under the Warrants and the
Warrant Agreement shall thereupon cease; provided that each Warrant shall be
exercised (even if such Warrant would not otherwise be exercisable on such date
because of the Limit Option) on the basis that the Valuation Date for such
Warrant shall be the Cancellation Date and the holder of each such Warrant will
receive, in lieu of the Cash Settlement Value of such Warrant, an amount (the
'Alternative Settlement Amount'), determined by the Determination Agent, which
is the greater of (i) the average of the last sale prices, as available, of the
Warrants on the CBOE (or any successor United States national securities
exchange on which the Warrants are listed) on the 30 trading days preceding the
date on which such Extraordinary Event was declared; provided that, if the
Warrants were not traded on the CBOE (or such successor securities exchange) on
at least 20 of such trading days, no effect will be given to this clause (i) for
the purpose of determining the Alternative Settlement Amount, and (ii) the
amount 'X' calculated using the formula set forth below:

                  X = I + [(T/2) x (A/B)]

        where
 
     I = the Cash Settlement Value of the Warrants determined as described
above, but subject to the following modifications:
 
          (1) if the Cancellation Date for such Warrants is a date on which the
     Index is calculated and published, for the purpose of determining 
     such Cash Settlement Value, the Index will be determined as of
     such Cancellation Date except that, if the Index Spot Price as of the
     Cancellation Date is less than 90% of the Index Spot Price as of the
     immediately preceding Index Calculation Day, then the Index Spot Price will
     be deemed to be 90% of the Index Spot Price on such preceding Index
     Calculation Day; or
 
          (2) if the Cancellation Date for such Warrants is a date on which the
     Index is not calculated or published, for the purpose of determining 
     such Cash Settlement Value, the Index Spot Price will be deemed to 
     be the lesser of (i) the Index Spot Price as of the first Index
     Calculation Day immediately preceding the Cancellation Date except that, if
     the Index Spot Price as of such day is less than 90% of the Index Spot
     Price as of the second Index Calculation Day immediately preceding such
     Cancellation Date, 90% of the Index Spot Price as of such second Index
     Calculation Day and (ii) the arithmetic average of four amounts, being (a)

     the Index Spot Price at each of the three successive Index Calculation Days
     immediately preceding the Cancellation Date and (b) the Index Spot Price at
     the next Index Calculation Day; provided that if an Extraordinary Event
     described in clause (i) of the definition of Extraordinary Event continues
     for 30 consecutive days immediately following such Cancellation Date, then
     the Determination Agent shall calculate an amount which, in its reasonable
     opinion, fairly reflects the value of the Underlying Stocks on
 
                                      S-32
<PAGE>
     the Index Calculation Day immediately following such Cancellation Date
     which, subject to approval by the Company (such approval not to be
     unreasonably withheld), shall for purposes of calculating the amount under
     this clause (2)(ii) be treated as the figure arrived at under clause
     (2)(ii)(b);
 
     T = U.S.$            , the initial offering price per Warrant;
 
     A = the total number of days from but excluding the Cancellation Date for
such Warrants to and including the Expiration Date; and
 
     B = the total number of days from but excluding the date on which the
Warrants were initially sold to and including the Expiration Date.
 
     For the purposes of determining 'I' in the above formula, in the event that
the Determination Agent and the Company are required, but have not, after good
faith consultation with each other and within five days following the first day
upon which such Alternative Settlement Amount may be calculated in accordance
with the above formula, agreed upon a figure under clause (2)(ii)(b) which
fairly reflects the value of the Underlying Stocks on the Cancellation Date,
then the Determination Agent shall promptly nominate a third party, subject to
approval by the Company (such approval not to be unreasonably withheld), to
determine such figure and calculate the Alternative Settlement Amount in
accordance with the above formula. Such party shall act as an independent expert
and not as an agent of the Company or the Determination Agent, and its
calculation and determination of the Alternative Settlement Amount shall, absent
manifest error, be final and binding on the Company, the Warrant Agent, the
Determination Agent and the Warrantholders. Any such calculations will be made
available to a Warrantholder for inspection at the Warrant Agent's Office.
Neither the Company nor such third party shall have any responsibility for good
faith errors or omissions in calculating the Alternative Settlement Amount.
 
     Exercise Limitation Events.  The Warrant Agreement will provide that if the
Company determines that on an Applicable Tokyo Business Day an Exercise
Limitation Event has occurred and is continuing, then the Cash Settlement Value
in respect of an exercise shall be calculated on the basis that the Valuation
Date shall be the next Index Calculation Day following an Applicable Tokyo
Business Day on which there is no Exercise Limitation Event or Extraordinary
Event; provided that, if the Valuation Date has not occurred on or prior to the
Expiration Date or the Delisting Date, the Warrantholders will receive the
Alternative Settlement Amount in lieu of the Cash Settlement Value which shall
be calculated as if the Warrants had been cancelled on the Expiration Date or
the Delisting Date, as the case may be. The Company shall promptly give notice
to Warrantholders, by publication in a United States newspaper with a national

circulation (currently expected to be The Wall Street Journal), if an Exercise
Limitation Event shall have occurred.
 
     'Exercise Limitation Event' means either of the following events:
 
          (i) a suspension or absence of trading on the TSE of 20% or more of
     the Underlying Stocks which then comprise the Index; or
 
          (ii) the suspension or material limitation on the Singapore
     International Monetary Exchange, Ltd. ('SIMEX'), Osaka Securities Exchange
     ('OSE') or any other major futures or securities market (which as of the
     date of this Prospectus Supplement includes only SIMEX, OSE or the CBOE,
     but which in the Company's judgment may change in the future) of trading in
     futures or options contracts related to the Index, the Tokyo Stock Price
     Index ('TOPIX'), the Nikkei 225 Index or the Nikkei 300 Index.
 
     For purposes of determining whether an Exercise Limitation Event has
occurred: (1) a limitation on the hours or number of days of trading will not
constitute an Exercise Limitation Event if it results from an announced change
in the regular business hours of the relevant exchange, (2) a decision to
permanently discontinue trading in the relevant contract will not constitute an
Exercise Limitation Event, (3) a suspension in trading in a futures or options
contract referred to in clauses (i) and (ii) above, by reason of (x) a price
change violating limits set by the TSE, SIMEX, OSE or the CBOE or such futures
or securities market, (y) an imbalance of orders relating to such contracts or
(z) 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 Index, (4) an 'absence of trading' on the TSE will not include
any time when the TSE is closed for trading under ordinary circumstances and (5)
the occurrence of an Extraordinary Event described in clause (i) of the
definition of Extraordinary Event will not constitute, and will supersede the
occurrence of, an Exercise Limitation Event.
 
     Based on information provided to the Company by the TSE, it is the
Company's understanding that during the past six years there have been no
suspensions of trading on the TSE and no suspensions of trading on the OSE
 
                                      S-33
<PAGE>
that could have constituted an Exercise Limitation Event, except for the 1989
Event and a suspension of trading on the OSE of futures and options on January
17, 1995 as a result of the Kobe earthquake. The Company has not, however,
verified with the TSE, SIMEX, OSE or the CBOE, and makes no representations
concerning, whether any suspensions or trading by reason of a price change
violating limits set by the TSE, SIMEX, OSE or the CBOE or any absences of
trading during such period could have constituted an Exercise Limitation Event.
The lack or occurrence of such suspensions over the period indicated is not
necessarily indicative of the number or frequency of any future suspensions.
 
     In the case of a postponed Valuation Date resulting from an Extraordinary
Event or an Exercise Limitation Event, if the Company has made adequate funds
available to the Warrant Agent by 3:00 P.M., New York City time, on the third
New York Business Day following the date on which the Cash Settlement Value or
Alternative Settlement Amount, as the case may be, has been calculated, the

Warrant Agent will thereafter be responsible for making payment available to
each registered holder who holds Warrants in certificated form in the form of a
cashier's check or official bank check, or (in the case of payments of at least
$100,000) by wire transfer to a U.S. dollar bank account maintained by such
holder in the United States (at such holder's election), in an amount equal to
the aggregate Cash Settlement Value or Alternative Settlement Amount as
applicable, of such holder's exercised Warrants. In the case of Warrants held
through the facilities of DTC, CEDEL or Euroclear, if the Company has made such
funds available by such time as noted above, the Warrant Agent will thereafter
be responsible for making funds available to DTC in an amount sufficient to pay
the Cash Settlement Value or Alternative Settlement Amount of the Warrants. DTC
will be responsible for disbursing such funds to each appropriate Participant
(including Citibank and Morgan who in turn will disburse payments to CEDEL and
Euroclear, as the case may be, who will be responsible for disbursing such
payments to their respective participants who, in turn, will be responsible for
disbursing such payments to the Warrantholders represented by each such
participant) and each such Participant will be responsible for disbursing such
payments to the Warrantholders it represents and to each brokerage firm for
which it acts as agent. Each such brokerage firm will be responsible for
disbursing funds to the Warrantholders it represents.
 
     Certain of the Extraordinary Events and Exercise Limitation Events may be
events that would tend to increase the level of the Index and accordingly
decrease the Cash Settlement Value for the Warrants following the occurrence of
any such Extraordinary Event or Exercise Limitation Event. However, as a result
of any postponed exercise as described above, Warrantholders would not receive
such Cash Settlement Value, but would receive instead a Cash Settlement Value
(or, if applicable, an Alternative Settlement Amount) determined as of a later
date. In any such case, any immediate impact of the related Extraordinary Event
or Exercise Limitation Event on the Index may have been negated by interim
market and other developments and, as a result of any such postponement, the
Cash Settlement Value (or Alternative Settlement Amount) actually received by
Warrantholders may be substantially lower (including zero) than the otherwise
applicable Cash Settlement Value if the valuation for the Warrants had not been
postponed.
 
LISTING
 
     The Warrants have been approved for listing on the CBOE, subject to
official notice of issuance. The CBOE symbol for the Warrants is JXP.WS. The
CBOE expects to cease trading in the Warrants on such Exchange as of the close
of business on the Expiration Date.
 
DELISTING OF WARRANTS
 
     In the event the Warrants are delisted from, or permanently suspended from
trading on (within the meaning of the Exchange Act and the rules and regulations
thereunder), the CBOE and not accepted at the same time for listing on another
United States national securities exchange, Warrants not previously exercised
will be deemed automatically exercised on the last New York Business Day prior
to the effective date of such delisting or trading suspension (the 'Delisting
Date'), and the Cash Settlement Value, if any, shall be calculated and settled
as provided above under 'Automatic Exercise.' The Company will notify
Warrantholders as soon as practicable of such delisting or trading suspension.

However, if the Company first receives notice of the delisting or suspension on
the same day on which the Warrants are delisted or suspended, such day will be
deemed the Delisting Date. The Company will covenant in the Warrant Agreement
that it will not seek delisting of the Warrants from, or suspension of their
trading on, the CBOE unless the Company has, at the same time, arranged for
listing of the Warrants on another United States national securities exchange.

                    CERTAIN UNITED STATES FEDERAL INCOME TAX
                     CONSIDERATIONS CONCERNING THE WARRANTS
 
     The following is a summary of certain anticipated United States Federal
income tax consequences of an investment in the Warrants and represents the
views of Brown & Wood, special tax counsel to the Company. Such views are based
upon laws, regulations, rulings and decisions now in effect, all of which are
subject to change (possibly with retroactive effect) or possible differing
interpretations. The following discussion of certain United States Federal
income tax consequences to beneficial owners of the Warrants applies only to a
person who holds a Warrant as a capital asset and does not purport to address
the United States Federal income tax consequences to special classes of
investors including persons who are securities, currencies or options dealers,
or persons who may hold the Warrants as part of an integrated transaction (e.g.,
as part of a hedge or straddle for tax purposes). Prospective purchasers of
Warrants are urged to consult their own tax advisors as to the application of
United States Federal income tax laws to their particular situations as well as
any consequences of the purchase, ownership and disposition of the Warrants
arising under the laws of any other taxing jurisdiction.
 
     As used herein, the term 'U.S. Holder' means a beneficial owner of a
Warrant that is for United States Federal income tax purposes (i) a citizen or
resident of the United States, (ii) a corporation, partnership or other entity
created or organized in or under the laws of the United States or of any
political subdivision thereof, (iii) an estate or trust the income of which is
subject to United States Federal income taxation regardless of its source or
(iv) any other person whose income or gain in respect of a Warrant is
effectively connected with the conduct of a United States trade or business. As
used herein, the term 'non-U.S. Holder' means a beneficial owner of a Warrant
that is not a U.S. Holder.
 
U.S. HOLDERS
 
     Although there is no authority directly dealing with instruments such as
the Warrants, pursuant to Revenue Ruling 94-63, each Warrant should be treated
as a 'non-equity' option for purposes of Section 1256 of the Internal Revenue
Code of 1986, as amended (the 'Code'), which must be 'marked-to-market.'
Accordingly, a U.S. Holder of a Warrant should be required to treat such Warrant
as if sold for its fair market value on the last business day of each of the
U.S. Holder's taxable years (assuming that the U.S. Holder has not previously
disposed of the Warrant) and should be required to recognize taxable gain or
loss for each such taxable year in an amount equal to the difference between the
fair market value of the Warrant on the last business day of each such taxable
year and such U.S. Holder's adjusted tax basis in the Warrant. Thus, a U.S.

Holder of a Warrant may incur United States Federal income tax liability on an
annual basis in respect of any increase in the value of a Warrant without a
corresponding receipt of cash. In addition, a U.S. Holder should be required to
recognize taxable gain or loss upon the sale, exchange, exercise or expiration
of the Warrant in an amount equal to the difference between the amount realized
upon such sale, exchange, exercise or expiration and the U.S. Holder's adjusted
tax basis in such Warrant. For these purposes, a U.S. Holder's adjusted tax
basis in a Warrant would equal such U.S. Holder's initial investment in the
Warrant, increased or decreased by any net gain or loss recognized by the U.S.
Holder in respect of the Warrant in prior taxable years. Any gain or loss
recognized by a U.S. Holder in accordance with the preceding rules would
generally be treated as 60 percent long-term capital gain or loss and 40 percent
short-term capital gain or loss.
 
NON-U.S. HOLDERS
 
     In general, gains realized on the sale, exchange or exercise of a Warrant
by a non-U.S. Holder will not be subject to United States Federal income or
withholding tax in respect of such amounts, assuming the income is not
effectively connected with a United States trade or business of the non-U.S.
Holder. Certain other exceptions may be applicable, and a non-U.S. Holder should
consult its own tax advisor in this regard.
 
     Under current law, the fair market value of a Warrant may be includible in
the estate of an individual non-U.S. Holder for United States Federal estate tax
purposes, unless an applicable estate tax treaty provides otherwise. Individual
non-U.S. Holders should consult their own tax advisors concerning the United
States Federal estate tax consequences, if any, of investing in the Warrants.
 
                                      S-35
<PAGE>
BACKUP WITHHOLDING
 
     A beneficial owner of a Warrant will be subject to backup withholding at
the rate of 31 percent with respect to the gross proceeds upon a sale or
exercise of a Warrant if such beneficial owner fails to supply an accurate
taxpayer identification number (or fails to comply with certain other
requirements) and does not establish, when required, that it is an exempt
recipient or a non-U.S. Holder. Any amount withheld under the backup withholding
rules would be allowed as a refund or a credit against the beneficial owner's
United States Federal income tax provided the required information is furnished
to the IRS.
 
                                  UNDERWRITING
 
     Subject to the terms and conditions set forth in the underwriting
agreement, dated the date hereof (the 'Underwriting Agreement'), the Company has
agreed to sell to each of the Underwriters named below, and each of the
Underwriters has severally agreed to purchase, the number of Warrants set forth
opposite its name.

     The Underwriters have advised the Company that they propose to offer the
Warrants to the public initially at the offering price set forth on the cover
page of this Prospectus Supplement, except that the price will be $
per Warrant for the purchase of 100,000 or more Warrants in any single
transaction, subject to the holding periods described below. In addition, the
Underwriters propose to offer the Warrants to certain dealers at a price that
represents a concession not in excess of $     per Warrant. The Underwriters may
allow and such dealers may reallow a concession not in excess of $     per
Warrant to certain other dealers. After the initial public offering, the public
offering price and such concessions may be changed.
 
     Generally, delivery of approximately 97.5% of the Warrants (the 'Delivered
Warrants') purchased by an investor at the reduced price will be made on the
date of delivery of the Warrants referred to on the cover of this Prospectus
Supplement. The balance of approximately 2.5% of the Warrants (the 'Retained
Warrants') purchased by each such investor will be held by PaineWebber and
delivered to such investor if the investor and any accounts in which the
investor may have deposited any of its Delivered Warrants have held all of the
Delivered Warrants for 45 days following the date of this Prospectus Supplement
or any shorter period deemed appropriate by PaineWebber. If an investor or any
account in which the investor has deposited any of its Delivered Warrants fails
to satisfy the holding period requirement, as determined by PaineWebber, all of
the investor's Retained Warrants will be forfeited by the investor and not
delivered to it. The Retained Warrants will instead be delivered to the
Underwriters for sale to investors or disposed of as otherwise determined by
PaineWebber. This forfeiture will have the effect of increasing the purchase
price per Warrant for such investors to $     , the price referred to on the
front cover of this Prospectus Supplement. Should investors who are subject to
the holding period requirement sell their Warrants once the holding period is no
longer applicable, the market price of the Warrants may be adversely affected.
 
     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will purchase all the Warrants if any are purchased. The Company
has agreed to indemnify the Underwriters against, and to contribute to losses
arising out of, certain liabilities, including liabilities under the Securities
Act of 1933, as amended.
 
     PaineWebber is a wholly owned subsidiary of the Company. The participation
of PaineWebber in the offer and sale of the Warrants complies with the
requirements of Schedule E of the By-Laws of the NASD ('Schedule E') regarding
underwriting securities of an affiliate. Under the provisions of Schedule E,
when a NASD member such as PaineWebber distributes securities of an affiliate,

the price of the securities can be no higher than that recommended by a
'qualified independent underwriter,' as such term is defined in Schedule E,
meeting certain standards. In accordance with such requirements,
               has agreed to serve as 'qualified
 
                                      S-36
<PAGE>
independent underwriter' and has conducted due diligence and has recommended a
price for the Warrants in compliance with the requirements of Schedule E.
 
     The Company or its subsidiaries or third parties, including the
Underwriters or their affiliates, may also be the writers of one or more hedges.
 
     Each Underwriter has represented that (i) it has complied and will comply
with all applicable provisions of the United Kingdom Financial Services Act 1986
with respect to anything done by it in relation to the Warrants in, from or
otherwise involving the United Kingdom and (ii) it has only issued or passed on,
and will only issue or pass on, in the United Kingdom any document received by
it in connection with the issue of the Warrants to a person who is of a kind
described in Article 9(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1988 or is a person to whom the document may
otherwise lawfully be issued or passed on.
 
     The Warrants have not been and will not be registered under the Securities
and Exchange Law of Japan and, subject to certain exceptions, may not be offered
or sold directly or indirectly in Japan or to the residents thereof. Exercise of
the Warrants may be conditioned upon certification as to non-Japanese beneficial
ownership.
 
     PaineWebber, as Determination Agent, is expected to make certain
determinations in connection with the Warrants, including the determination of
the Index Spot Price to be used in calculating the Cash Settlement Value or
Alternative Settlement Amount of the Warrants and the Limit Option Reference
Rate and any determination of the Alternative Settlement Amount.
 
                                 LEGAL OPINIONS
 
     The validity of the Warrants will be passed upon for the Company by
Cravath, Swaine & Moore, New York, New York, and for the Underwriters by Brown &
Wood, New York, New York. Brown & Wood will also pass upon certain United States
Federal income tax matters relating to the Warrants.

PROSPECTUS
                            Paine Webber Group Inc.

                              STOCK INDEX WARRANTS

                            ------------------------
 
     Paine Webber Group Inc. (the 'Company') intends to issue from time to time
warrants ('Warrants') entitling the holders to receive, upon exercise, an amount
in cash determined by reference to decreases (such Warrants, 'Put Warrants') or
increases (such Warrants, 'Call Warrants') in the level of a specified stock
index (the 'Stock Index') which may be based on United States or foreign stocks
or a combination thereof (the 'Underlying Stocks'). No shares of any Underlying
Stock will be delivered upon exercise of the Warrants. Unless otherwise
specified in the accompanying Prospectus Supplement (the 'Prospectus
Supplement'), the Stock Index will be an established, broadly-based index
related to a major domestic or foreign equity trading market. The Warrants will
have an aggregate initial public offering price or purchase price of up to U.S.
$346,242,000 or the equivalent thereof if the offering price or purchase price
of the Warrants is denominated in a foreign currency or composite currency.
Unless otherwise specified in the Prospectus Supplement, payments, if any, on
the Warrants will be made in U.S. dollars. The Warrants will be offered on terms
to be determined at the time of sale.
 
     With regard to the Warrants in respect of which this Prospectus is being
delivered, the Prospectus Supplement sets forth the aggregate amount and
offering price of such Warrants, certain information regarding the applicable
Stock Index and the Underlying Stocks, whether such Warrants are Put Warrants or
Call Warrants, the date on which the right to exercise such Warrants commences
and the expiration date of such Warrants, the manner in which such Warrants may
be exercised and any restrictions on, or other special provisions relating to,
the exercise of such Warrants, whether and under what circumstances such
Warrants may be cancelled by the Company prior to their expiration date, the
method of determining the amount payable in connection with the exercise or
cancellation of such Warrants, including the predetermined amount to which the
level of the Stock Index upon exercise of such Warrants is compared, the method
of translating movements in the Stock Index into a cash amount in the currency
in which such Warrants are payable, including, for Warrants relating to a Stock
Index for which the trading prices of Underlying Stocks are expressed in a
foreign currency (a 'Foreign Stock Index'), the method of converting amounts in
such foreign currency into U.S. dollars (or such other currency in which such
Warrants are payable), the amount payable on cancellation of such Warrants, if
applicable (the 'Cancellation Amount'), and the predetermined sum or range of
sums (the 'Minimum Expiration Value'), if any, payable in certain circumstances
upon expiration or exercise of such Warrants, any national securities exchange
on which such Warrants will be listed, certain U.S. federal income tax
consequences relating to such Warrants and any other specific terms of, or
information regarding, such Warrants.
 
     The Warrants involve a high degree of risk, including risks arising from
fluctuations in the values of the Underlying Stocks, risks relating to the Stock
Index, general risks applicable to the stock market (or markets) on which the

Underlying Stocks are traded and, in the case of Warrants relating to a Foreign
Stock Index and settled based on then-current currency exchange rates, foreign
exchange risks. Purchasers should recognize that their Warrants, other than
Warrants having a Minimum Expiration Value, may expire worthless. Purchasers
should be prepared to sustain a total loss of the purchase price of their
Warrants, and are advised to consider carefully the information under 'Risk
Factors' herein and the information regarding the Warrants and the Stock Index
set forth in the Prospectus Supplement.

                            ------------------------
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
      EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
          SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
            COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
              PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.
 
     The Warrants may be sold by the Company directly to purchasers, through
agents designated from time to time, through underwriting syndicates led by one
or more managing underwriters or through one or more underwriters. Any such
managing underwriters, underwriters or agents may include PaineWebber
Incorporated ('PaineWebber'). If underwriters or agents are involved in the
offering of any Warrants, the names of such underwriters or agents will be set
forth in the Prospectus Supplement. If an underwriter, agent or dealer is
involved in the offering of any Warrants, the underwriter's discount, agent's
commission or dealer's purchase price will be set forth in, or may be calculated
from the information set forth in, the Prospectus Supplement, and the net
proceeds to the Company from such offering will be the public offering price of
the Warrants less such discount in the case of an offering through an
underwriter or the purchase price of the Warrants less such commission in the
case of an offering through an agent, and less, in each case, the other expenses
of the Company associated with the issuance and distribution of the Warrants.
 
     PaineWebber expects to offer and sell previously issued Warrants from time
to time in the course of its business as a broker-dealer. PaineWebber may act as
principal or agent in such transactions. See 'Plan of Distribution'.

                                  RISK FACTORS
 
     The Warrants involve a high degree of risk, including risks arising from
fluctuations in the prices of the Underlying Stocks, risks relating to the Stock
Index, general risks applicable to the stock market (or markets) on which the
Underlying Stocks are traded and, in the case of Warrants relating to a Foreign
Stock Index and settled based on then-current currency exchange rates, foreign
exchange risks. Prospective purchasers of the Warrants should recognize that
their Warrants, other than Warrants having a Minimum Expiration Value, may
expire worthless. Purchasers should be prepared to sustain a total loss of the
purchase price of their Warrants. Prospective purchasers of the Warrants should
be experienced with respect to options and options transactions and understand
the risks of stock index (and, if applicable, foreign currency) transactions and
should reach an investment decision only after careful consideration, with their
advisers, of the suitability of the Warrants in light of their particular
financial circumstances, the information set forth below and under 'Description
of Warrants' herein and the information regarding the Warrants and the Stock
Index set forth in the Prospectus Supplement.
 
POSSIBLE ILLIQUIDITY OF SECONDARY MARKET
 
     It is not possible to predict how the Warrants will trade in the secondary
market or whether such market will be liquid or illiquid. The Company intends to
list the Warrants of each issue on a national securities exchange. In the event
of a delisting or suspension of trading on such exchange, the Company will use
its best efforts to list the Warrants on another national securities exchange.
If the Warrants are not listed or traded on any securities exchange, pricing
information for the Warrants may be more difficult to obtain and the liquidity
of the Warrants may be adversely affected. To the extent Warrants are exercised,
the number of Warrants outstanding will decrease, resulting in a lessening of
the liquidity of the Warrants.
 
RELATIONSHIP BETWEEN CASH SETTLEMENT VALUE AND STOCK INDEX LEVEL
 
     Each Warrant will entitle the Warrantholder to receive from the Company
upon exercise thereof a cash value (the 'Cash Settlement Value') that (i) in the
case of a Put Warrant, will be determined by reference to the amount, if any, by
which a predetermined level or range of levels of the Stock Index (the 'Strike
Index') exceeds the then-current level of the Stock Index (the 'Spot Index') at
the close of business on the relevant exchange or exchanges, and (ii) in the

case of a Call Warrant, will be determined by reference to the amount, if any,
by which the Spot Index at the time of exercise of such Warrant exceeds the
Strike Index. However, a Warrantholder will receive a cash payment upon exercise
only if the Warrants are 'in-the-money'--that is, have a Cash Settlement Value
greater than zero at the time--except that, in the case of Warrants having a
Minimum Expiration Value, in certain circumstances the Warrantholder will
receive upon expiration or exercise a cash payment in an amount equal to the
greater of the applicable Cash Settlement Value and such Minimum Expiration
Value. The Cash Settlement Value of a Put Warrant will be greater than zero only
if the Spot Index at the time of exercise is less than the Strike Index for such
Put Warrant (that is, if the level of the Stock Index drops below the
predetermined Strike Index). The Cash Settlement Value of a Call Warrant will be
greater than zero only if the Strike Index for such Call Warrant is less than
the Spot Index at the time of exercise (that is, if the level of the Stock Index
rises above the predetermined Strike Index).
 
EXTRAORDINARY EVENTS; EXERCISE LIMITATION EVENTS; CANCELLATION OF WARRANTS;
DELAYED EXERCISE
 
     If so specified in the Prospectus Supplement, the Warrants of an issue may
be cancelled by the Company upon the occurrence of one or more events
('Extraordinary Events') described in the Prospectus Supplement. In such event,
Warrantholders will have the right to receive only the Cancellation Amount,
which may be a predetermined amount, or an amount to be determined in accordance
with a predetermined formula, specified in such Prospectus Supplement. Certain
events that may constitute Extraordinary Events and therefore lead to
cancellation of the Warrants of an issue may be events that would tend to
increase the Cash Settlement Value otherwise applicable to the Warrants of such
issue. In addition, if so specified in the Prospectus Supplement, any exercise
of the Warrants may be suspended by the Company, and the valuation of and
payment for such Warrants may be postponed and/or the determination of the Cash
Settlement Amount thereof may be made on a different basis, upon the occurrence
of an Extraordinary Event or certain other events ('Exercise Limitation Events')
specified in the Prospectus Supplement.

CERTAIN FACTORS AFFECTING VALUE AND TRADING PRICE OF WARRANTS
 
     Unless otherwise specified in the Prospectus Supplement, the Warrants of
each issue will have a Cash Settlement Value of zero at the time of the initial
public offering of such Warrants. The Cash Settlement Value of the Warrants at
any time prior to expiration is expected typically to be less than the trading
price of the Warrants at that time. The difference between the trading price and
the Cash Settlement Value will reflect, among other things, a 'time value' for
the Warrants. The 'time value' of the Warrants will depend partly upon the
length of the period remaining to expiration and expectations concerning the
level of the Stock Index as compared to the Strike Index during the period. In
the case of Warrants relating to a Foreign Stock Index and settled based on
then-current currency exchange rates, such 'time value' will also depend in part
on expectations concerning the value of the related foreign currency as compared
to the U.S. dollar (or such other currency in which such Warrants are payable)
during such period. Before exercising or selling Warrants, Warrantholders should
carefully consider, among other things, (i) the trading price of the Warrants,

(ii) the level of the Stock Index at such time, (iii) the time remaining to
expiration, (iv) in the case of Warrants relating to a Foreign Stock Index and
settled based on then-current currency exchange rates, the exchange rate between
the related foreign currency and the U.S. dollar (or such other currency in
which such Warrants are payable) at such time, (v) the probable range of Cash
Settlement Values, (vi) any Minimum Expiration Value and (vii) any related
transaction costs.
 
     The trading price of a Warrant at any time is expected to be dependent on
(i) the relationship between the Strike Index and the level of the Stock Index
at such time, (ii) in the case of Warrants relating to a Foreign Stock Index and
settled based on then-current currency exchange rates, the exchange rate between
the related foreign currency and the U.S. dollar (or such other currency in
which such Warrants are payable) at such time, (iii) any Minimum Expiration
Value and (iv) a number of other interrelated factors, including those listed
below. The relationship among these factors is complex. However, the expected
effect on the trading price of a Warrant of each of the factors listed below,
assuming in each case that all other factors are held constant, is as follows:
 
          (1) The prevailing level of the Stock Index. If the level of the Stock
     Index falls in relation to the Strike Index, the trading price of a Put
     Warrant is expected to increase and the trading price of a Call Warrant is
     expected to decrease; if the level of the Stock Index rises in relation to
     the Strike Index, the trading price of a Put Warrant is expected to
     decrease and the trading price of a Call Warrant is expected to increase.
     However, as a result of other factors, the trading price of a Warrant may
     decline significantly even if, in the case of a Put Warrant, there is a
     decrease in the level of the Stock Index as compared to the Strike Index
     or, in the case of a Call Warrant, there is an increase in the level of the
     Stock Index as compared to the Strike Index.
 
          (2) The volatility of the Stock Index. If volatility increases, the
     trading price of both Put and Call Warrants is expected to increase; if
     volatility decreases, the trading price of both Put and Call Warrants is
     expected to decrease.
 
          (3) The time remaining to the expiration date of the Warrants. As the
     time remaining to the expiration date of the Warrants decreases, the
     trading price of both Put and Call Warrants is expected to decrease.
 
          (4) The prevailing interest rates. If interest rates in the country
     where the Underlying Stocks trade increase, the trading value of a Put
     Warrant is expected to decrease and the trading value of a Call Warrant is
     expected to increase. If such interest rates decrease, the trading value of
     a Put Warrant is expected to increase and the trading value of a Call
     Warrant is expected to decrease. Increases and decreases in other interest
     rates may also affect the value of the Warrants.
 
          (5) Dividend rates. If dividend rates on the Underlying Stocks
     increase, the trading value of a Put Warrant is expected to increase and
     the trading value of a Call Warrant is expected to decrease; however,
     increased dividend rates may positively affect the value of the Stock
     Index, and the trading value of a Put Warrant could then be expected to
     decrease and the trading value of a Call Warrant could then be expected to

     increase. If such dividend rates decrease, the trading value of a Put
     Warrant is expected to decrease and the trading value of a Call Warrant is
     expected to increase; however, decreased dividend
 
                                       4
<PAGE>
     rates may adversely affect the value of the Stock Index, and the trading
     value of a Put Warrant could then be expected to increase and the trading
     value of a Call Warrant could then be expected to decrease.
 
          (6) The prevailing currency exchange rate. In the case of Warrants
     relating to a Foreign Stock Index and settled based on then-current
     currency exchange rates, if the value of the U.S. dollar (or such other
     currency in which such Warrants are payable) falls in relation to the
     related foreign currency, the trading price of both Put and Call Warrants
     is expected to increase; if the value of the U.S. dollar (or such other
     currency) rises in relation to the related foreign currency, the trading
     price of both Put and Call Warrants is expected to decrease.
 
     Some of the factors referred to above are in turn influenced by various
     political, economic and other factors referred to herein and in the
     Prospectus Supplement that can affect trading prices of the Underlying
     Stocks and the level of the applicable Stock Index (and, if applicable,
     currency exchange rates).
 
TIME LAG AFTER EXERCISE AND POTENTIAL INTERIM CHANGES IN STOCK INDEX
 
     Unless otherwise specified in the Prospectus Supplement, in the case of any
exercise of Warrants, there will be a time lag between the time a Warrantholder
gives instructions to exercise and the time the Spot Index relating to such
exercise and, in the case of Warrants relating to a Foreign Stock Index and
settled based on then-current currency exchange rates, the applicable currency
exchange rate, are determined. The delay will, at a minimum, amount to almost an
entire day and could be much longer, particularly in the case of a delay in
exercise of Warrants arising from any daily maximum exercise limitation as
described in the immediately following paragraph or following the occurrence of
an Extraordinary Event or an Exercise Limitation Event as described under
'Extraordinary Events; Exercise Limitation Events; Cancellation of Warrants;
Delayed Exercise' above. The level of the Stock Index and, if applicable, the
exchange rate between the related foreign currency and the U.S. dollar (or such
other currency in which the Warrants are payable) may change significantly
during any such period, and such movement or movements could decrease the Cash
Settlement Value of the Warrants being exercised and may result in such Cash
Settlement Value being zero.
 
LIMITATIONS ON EXERCISE
 
     If so indicated in the Prospectus Supplement, the Company will have the
option to limit the number of Warrants exercisable on any date to the maximum
number specified in the Prospectus Supplement and, in conjunction with such
limitation, to limit the number of Warrants exercisable by any person or entity
on such date. In the event that the total number of Warrants being exercised on
any date exceeds such maximum number and the Company elects to limit the number
of Warrants exercisable on such date, a Warrantholder may not be able to

exercise on such date all Warrants that such holder desires to exercise.
Warrants to be exercised on such date will be selected on a pro rata basis or in
any other manner specified in the Prospectus Supplement. Unless otherwise
specified in the Prospectus Supplement, the Warrants tendered for exercise but
not exercised on such date will be automatically exercised on the next date on
which Warrants may be exercised, subject to the same daily maximum limitation
and delayed exercise provisions described in this paragraph. Unless otherwise
specified in the Prospectus Supplement, any such limitation will not apply to
cases of automatic exercise, including at expiration.
 
MINIMUM EXERCISE AMOUNT
 
     If so indicated in the Prospectus Supplement, a Warrantholder must tender a
specified minimum number of Warrants at any one time in order to exercise
(except for cases of automatic exercise, including at expiration). Thus, except
in such cases, Warrantholders with fewer than the specified minimum number of
Warrants will either have to sell their Warrants or purchase additional
Warrants, incurring transaction costs in each case, in order to realize upon
their investment. Furthermore, such Warrantholders incur the risk that there may
be differences between the trading price of the Warrants and the Cash Settlement
Value of such Warrants.
 
                                       5
<PAGE>
OFFERING PRICE OF WARRANTS
 
     The initial offering price of the Warrants may be in excess of the price
that a commercial user of options might pay for a comparable option in a
private, less liquid transaction.
 
CERTAIN RISK CONSIDERATIONS
 
     The purchaser of a Warrant may lose his entire investment except to the
extent of any Minimum Expiration Value that such Warrant may have. This risk
reflects the nature of a Warrant as an asset which, other factors held constant,
tends to decline in value over time and which may, depending on the prevailing
level of the Stock Index as compared to the Strike Index, become worthless when
it expires (except to the extent of any Minimum Expiration Value). Assuming all
other factors are held constant, the more a Warrant is 'out-of-the-money' and
the shorter its remaining term to expiration, the greater the risk that a
purchaser of the Warrant will lose all or part of his investment. This means
that a Warrantholder who does not either exercise or sell his Warrant prior to
expiration will necessarily lose his entire investment in the Warrant upon
expiration (except to the extent of any Minimum Expiration Value) if, in the
case of a Put Warrant, the Spot Index at expiration is greater than or equal to
the Strike Index or, in the case of a Call Warrant, such Spot Index is less than
or equal to the Strike Index.
 
     The risk of the loss of some or all of the purchase price of a Warrant upon
expiration means that a purchaser of a Warrant must generally be correct about
both the direction and magnitude of an anticipated change in the level of the
Stock Index in relation to the Strike Index and must also be correct about when
such change will occur. In the case of Warrants relating to a Foreign Stock
Index and settled based on then-current currency exchange rates, purchasers

should also consider expected changes in the value of the related foreign
currency as compared to the U.S. dollar (or such other currency in which such
Warrants are payable). If the level of the Stock Index as compared to the Strike
Index does not decline, in the case of a Put Warrant, or does not rise, in the
case of a Call Warrant, before the Warrant expires to an extent sufficient
(giving effect to currency exchange rate movements in the case of a Warrant
relating to a Foreign Stock Index and settled based on then-current currency
exchange rates) to cover a purchaser's cost of the Warrant (i.e., the purchase
price plus transaction costs, if any), the purchaser will lose all or part of
his investment in such Warrant upon expiration.
 
CERTAIN FACTORS AFFECTING STOCK INDEX
 
     The Cash Settlement Value of a Warrant at any time will depend primarily on
the level of the Stock Index at such time in relation to the Strike Index, which
level in turn will be based primarily on the trading prices of the Underlying
Stocks. Prospective purchasers of Warrants should familiarize themselves with
the basic features of the relevant Stock Index, including the Underlying Stocks
and the general method of calculation of such Stock Index. Unless otherwise
specified in the Prospectus Supplement, the Stock Index will be an established,
broadly-based index related to a major domestic or foreign equity trading
market. The general method of calculation of a Stock Index can significantly
influence the relationship between changes in the level of such Stock Index and
price movements in the Underlying Stocks. For example, a 'price-weighted' Stock
Index reflects only the prevailing prices of the Underlying Stocks, while a
'value-weighted' Stock Index is based on both the price and the number of
outstanding shares of each Underlying Stock (i.e., total market capitalization).
Thus, in a 'value-weighted' Stock Index (in contrast to a 'price-weighted' Stock
Index), changes in the stock price of a corporation with a large market
capitalization will generally have a greater influence on the level of the Stock
Index than changes in the stock price of a corporation with a small market
capitalization. Prospective purchasers are advised to consider carefully the
information set forth in the Prospectus Supplement regarding the Stock Index,
the Underlying Stocks and the method of calculation of the Stock Index.
 
     The trading prices of the Underlying Stocks will determine the level of the
related Stock Index. Prospective purchasers of the Warrants should recognize
that it is impossible to predict whether the level of a Stock Index will rise or
fall. Trading prices of the Underlying Stocks will be influenced by both the
complex and interrelated political, economic, financial and other factors that
can affect the capital markets generally and/or the equity trading market on
which the Underlying Stocks are trading and by the various circum-
 
                                       6
<PAGE>
stances that can influence the values of Underlying Stocks in a specific market
segment or particular Underlying Stocks.
 
     The levels of major market Stock Indexes are typically updated continually
during each trading day for the applicable equity trading market, with updated
levels disseminated at frequent intervals. However, Stock Index levels
ordinarily continue to be reported on a current basis even when trading is
interrupted in some or all of the Underlying Stocks. In that event, the reported
Stock Index level will be based on the current market prices of those Underlying

Stocks that are still being traded (if any) and the last reported prices of
those Underlying Stocks that are not currently trading. As a result, reported
Stock Index levels may at times be based on non-current price information with
respect to some or even all of the Underlying Stocks.
 
     Certain trading strategies involving purchases and sales of options on a
Stock Index, futures contracts on such Stock Index, options on such futures
contracts and portfolios of certain of the related Underlying Stocks can affect
the level of such Stock Index and, therefore, the trading price and Cash
Settlement Value of the related Warrants. These transactions and the resulting
changes in the Stock Index can occur at any time, but may occur more frequently
at or shortly before the regular expiration dates of the related options or
futures contracts.
 
CERTAIN RISKS RELATING TO FOREIGN STOCK INDEX
 
     In the case of a Foreign Stock Index where the Underlying Stocks are those
of non-U.S. issuers, the factors and circumstances that can affect the level of
such Stock Index will include foreign political, economic, financial and other
developments. Prospective purchasers of Warrants relating to a Foreign Stock
Index should consider such developments, which may not be as well known or as
rapidly or thoroughly reported in the U.S. as comparable U.S. developments.
Prospective purchasers of such Warrants should be aware of such possible lack of
availability of important information that can affect the level of the Foreign
Stock Index and must be prepared to make special efforts to obtain such
information on a timely basis.
 
     Special risks may also be presented in the case of Warrants relating to a
Foreign Stock Index where, because of differences in time zones between the
United States and the related foreign market, the Underlying Stocks are traded
on a foreign exchange that is not open when the trading market for the Warrants
in the United States is open and/or where trading occurs in the Underlying
Stocks during times when the trading market for the Warrants in the United
States is closed. In such cases, prospective purchasers of and holders of
Warrants may have to make investment and exercise decisions at times when
current pricing information regarding the Underlying Stocks comprising such
Foreign Stock Index is not available, and changes in the level of the Foreign
Stock Index may take place when the trading market for the Warrants in the
United States is closed. Such difference in time zones may also lengthen the
delay between the time when a Warrantholder is required to make a decision to
exercise Warrants and the time of calculation of the Spot Index. In addition,
the relevant equity trading market for a Foreign Stock Index will not be subject
to regulation by the Commission or any U.S. securities exchange.
 
POTENTIAL MODIFICATIONS OF STOCK INDEX
 
     The policies of the publisher of the Stock Index concerning additions,
deletions and substitutions of Underlying Stocks and the manner in which Stock
Index calculations take account of certain changes affecting the Underlying
Stocks (such as stock dividends and stock splits) can also significantly affect
the performance of such Stock Index. Additions, deletions or substitutions may
be necessary due to the disappearance of one or more Underlying Stocks as a
result of liquidations, mergers or other business combinations, or may be
occasioned by the publisher's view that a particular Underlying Stock is, for

example, no longer representative of a particular industry category. Although
Stock Indexes are normally calculated in a manner (typically involving
adjustments to the 'base' of the Stock Index) intended to ensure that such
additions, deletions, substitutions and changes do not, by themselves,
instantaneously change the level of the Stock Index, the level of the Stock
Index over time may be influenced by changes in the composition and
characteristics of the Underlying Stocks. Whether to add, delete or substitute
Underlying Stocks, and the method of adjusting the 'base' of the Stock Index in
respect of changes affecting the Underlying Stocks, are typically solely within
the discretion of the publisher of the Stock Index. In contrast to standardized
stock index options of the type issued by The Options Clearing Corporation
('OCC'), the terms of which may be
 
                                       7
<PAGE>
adjusted if the publisher of the related stock index changes the composition or
method of calculation of such stock index in a manner that causes a significant
discontinuity in the index level, the terms of the Warrants will not be adjusted
as a result of changes in the related Stock Index.
 
     The publisher of a Stock Index may replace such Stock Index with a
successor index or may cease publishing such Stock Index entirely. The
Prospectus Supplement specifies how the Cash Settlement Value of the related
Warrants will be determined in such circumstances. Although the method used will
generally be intended to enable Cash Settlement Values to be determined on as
consistent a basis as practicable, discontinuities may arise in such
circumstances. Moreover, information regarding the current level of certain
substitute indexes may not be readily available to Warrantholders, which may
adversely affect the trading market for their Warrants.
 
CERTAIN CONSIDERATIONS REGARDING HEDGING
 
     Prospective purchasers intending to purchase Warrants to hedge against the
market risk associated with investing in one or more individual Underlying
Stocks and/or other stocks should recognize the complexities of utilizing
Warrants in this manner. Historically, the prices of some stocks have tended to
be highly sensitive to factors influencing the market generally; others less so.
In addition, a stock's sensitivity to broad market influences may change over
time. Prospective purchasers intending to use Warrants in this manner should
also understand that they remain subject to issuer risk--that is, the risk that
factors affecting a particular issuer, such as its market position or the
quality of its management, may cause its stock to perform differently than the
market as a whole. In addition, prospective purchasers intending to utilize
Warrants to hedge a stock portfolio against market risk should understand that
unless the stocks in the portfolio exactly mirror the Underlying Stocks, the
portfolio and the Stock Index may respond differently to a given market
influence (including in different directions and to different extents). For this
reason, the use of Warrants for hedging purposes involves special risks that are
not present with 'true' hedges--i.e., hedges composed of options on the specific
stocks in the hedged position. These risks are greatest when Warrants relating
to a broadly-based Stock Index are used to hedge a non-diversified stock
position. In addition, in the case of Warrants relating to a Foreign Stock
Index, the effect of changes in the relevant currency exchange rate on the Cash
Settlement Value of such Warrants could complicate any hedging strategy.

 
CERTAIN FOREIGN CURRENCY EXCHANGE RISKS
 
     In the case of Warrants relating to a Foreign Stock Index and settled based
on then-current currency exchange rates, the Cash Settlement Value upon exercise
(assuming that such Cash Settlement Value is otherwise greater than zero) will
depend in part on the then-current exchange rate between the applicable foreign
currency and the U.S. dollar (or such other currency in which such Warrants are
payable). Purchasers of such Warrants are thus subject to foreign currency
exchange risks. Accordingly, such Warrants are not an appropriate investment for
prospective purchasers who are not experienced with respect to foreign currency
transactions. Foreign currency exchange risks include, among other things, the
possibility of significant changes in rates of exchange between the applicable
foreign currency and the U.S. dollar (or such other currency in which such
Warrants are payable) and the possibility of the imposition or modification of
exchange controls with respect to such foreign currency. Such risks generally
depend on the supply of and demand for the relevant currencies and economic and
political events. In recent years, rates of exchange for certain currencies have
been highly volatile, and such volatility may be expected in the future.
Fluctuations in any particular exchange rate that have occurred in the past are
not necessarily indicative, however, of fluctuations that may occur during the
term of any Warrant. Assuming all other factors are held constant, depreciation
in the value of the related foreign currency against the U.S. dollar (or such
other currency in which the Warrants are payable) can be expected to result in a
decrease in the trading price of Warrants relating to a Foreign Stock Index and
settled based on then-current currency exchange rates and a decrease in the Cash
Settlement Value otherwise payable upon exercise of such Warrants.
 
WARRANTS ARE UNSECURED OBLIGATIONS
 
     The Warrants are unsecured contractual obligations of the Company and will
rank on a parity with the Company's other unsecured contractual obligations and
with the Company's unsecured and unsubordinated debt. The Company expects to
issue several issues of Warrants relating to various Stock Indexes. At any
 
                                       8
<PAGE>
given time the number of Warrants outstanding may be substantial. The Warrants
are not standardized stock index options of the type issued by the OCC. For
example, unlike purchasers of OCC standardized options who have the credit
benefits of guarantees and margin and collateral deposits by OCC clearing
members to protect the OCC from a clearing member's failure, purchasers of
Warrants must look solely to the Company for performance of its obligations to
pay the Cash Settlement Value and, if applicable, the Minimum Expiration Value
upon the exercise or expiration of the Warrants. Further, the market for the
Warrants is not expected to be generally as liquid as the market for some OCC
standardized options.
 
COMPARISON WITH OTHER TYPES OF WARRANTS OR OPTIONS
 
     Options and warrants provide opportunities for investment and pose risks to
investors as a result of fluctuations in the value of the underlying investment
interests. Certain of the risks associated with the Warrants are similar to
those generally applicable to other options or warrants of private corporate

issuers. However, unlike options or warrants on equity or debt securities, which
are priced primarily on the basis of the present and expected value of a single
underlying security, the trading price of a Warrant is likely to reflect
primarily (i) the current and expected level of the Stock Index, (ii) the time
remaining until expiration, (iii) in the case of Warrants relating to a Foreign
Stock Index and settled based on then-current currency exchange rates, the spot
and forward currency exchange rates between the applicable foreign currency and
the U.S. dollar (or such other currency in which such Warrants are payable) and
(iv) if applicable, the Minimum Expiration Value.

     As may be described in further detail in the Prospectus Supplement, a
substantial portion of the proceeds to be received by the Company from the sale
of each issue of Warrants may be used by the Company or one or more of its
subsidiaries to purchase or maintain positions in certain of the Underlying
Stocks on which the related Stock Index is based or options, futures contracts
or options on futures contracts relating to such Stock Index or Underlying
Stocks, as the case may be, and, if applicable, to pay the costs and expenses of
hedging any currency risk with respect to such Warrants. The remainder of such
proceeds will be used by the Company or its subsidiaries for general corporate
purposes.

                            DESCRIPTION OF WARRANTS
 
     The following description of the terms of the Warrants sets forth certain
general terms and provisions of the Warrants to which any Prospectus Supplement
may relate. The particular terms of the Warrants offered by any Prospectus
Supplement and the extent, if any, to which such general provisions do not apply
to the Warrants so offered will be described in such Prospectus Supplement.
 
     Each issue of Warrants will be issued under a separate warrant agreement
(each, a 'Warrant Agreement') to be entered into between the Company and a bank
or trust company, as warrant agent (the 'Warrant Agent'), all as described in
the Prospectus Supplement relating to such Warrants. A single bank or trust
company may act as Warrant Agent for more than one issue of Warrants. The
Warrant Agent will act solely as the agent of the Company under the applicable
Warrant Agreement and will not assume any obligation or relationship of agency
or trust for or with any holders of such Warrants. A copy of the form of Warrant
Agreement, including the form of warrant certificate, is filed as an exhibit to
the Registration Statement. The following summaries of certain provisions of the
Warrants and the form of Warrant Agreement do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all of the
provisions of the Warrants and the Warrant Agreement.
 
     The Company will have the right to 'reopen' a previous issue of Warrants
and to issue additional Warrants of such issue.
 
GENERAL
 
     Each Warrant will entitle the Warrantholder to receive from the Company
upon exercise the Cash Settlement Value of such Warrant, which will be an amount
in cash (i) in the case of a Put Warrant, determined by reference to the amount,
if any, by which the Strike Index exceeds the Spot Index at the time of exercise
and (ii) in the case of a Call Warrant, determined by reference to the amount,
if any, by which the Spot Index at the time of exercise exceeds the Strike
Index. The Prospectus Supplement for an issue of Warrants will set forth the
formula pursuant to which the Cash Settlement Value of such Warrants will be
determined. The Strike Index may either be a fixed level of the Stock Index or a
level that varies during the term of the Warrants in accordance with a schedule
or formula. Certain Warrants will, if specified in the Prospectus Supplement,
entitle the Warrantholder to receive from the Company, upon automatic exercise
at expiration and under any other circumstances specified in the Prospectus
Supplement, an amount equal to the greater of the applicable Cash Settlement
Value and the Minimum Expiration Value of such Warrants. In addition, if so
specified in the Prospectus Supplement, following the occurrence of an
Extraordinary Event, the Cash Settlement Value of a Warrant may, at the option
of the Company, be determined on a different basis, including in connection with
automatic exercise at expiration. Unless otherwise specified in the Prospectus
Supplement, the Stock Index will be an established, broadly-based index related
to a major domestic or foreign equity trading market, and the Cash Settlement
Value, if any (and, if applicable, the Minimum Expiration Value), of the
Warrants will be payable in U.S. dollars.
 
     Unless otherwise indicated in the Prospectus Supplement, a Warrant will be
settled only in cash and, accordingly, will not require or entitle a

Warrantholder to sell, deliver, purchase or take delivery of any securities
(including the Underlying Stocks) to or from the Company, and the Company will
be under no obligation to, nor will it, purchase or take delivery of or sell or
deliver any securities (including the Underlying Stocks) from or to
Warrantholders pursuant to the Warrants.
 
     Unless otherwise specified in the Prospectus Supplement, the Warrants will
be deemed to be automatically exercised upon expiration. Upon such automatic
exercise, Warrantholders will be entitled to receive the Cash Settlement Value
of the Warrants, except that holders of Warrants having a Minimum Expiration
Value will be entitled to receive an amount equal to the greater of such Cash
Settlement Value and the applicable Minimum Expiration Value. The Minimum
Expiration Value may be either a fixed amount or an amount that varies during
the term of the Warrants in accordance with a schedule or formula. Any Minimum
Expiration Value applicable to an issue of Warrants, as well as any additional
circumstances resulting in the automatic exercise of such Warrants, will be
specified in the related Prospectus Supplement.
 
     If so specified in the Prospectus Supplement, the Warrants may be cancelled
by the Company upon the occurrence of an Extraordinary Event. Any Extraordinary
Events or Exercise Limitation Events relating to
 
                                       11
<PAGE>
an issue of Warrants will be set forth in the related Prospectus Supplement.
Upon such cancellation, the related Warrantholders will be entitled to receive
only the applicable Cancellation Amount specified in such Prospectus Supplement.
The Cancellation Amount may be either a fixed amount or an amount that varies
during the term of the Warrants in accordance with a schedule or formula.
 
     Reference is hereby made to the Prospectus Supplement relating to the
particular issue of Warrants offered thereby for the terms of such Warrants,
including, where applicable: (i) the aggregate amount of such Warrants; (ii) the
offering price of such Warrants; (iii) the Stock Index for such Warrants, which
may be based on United States or foreign stocks or a combination thereof and may
be a pre-existing U.S. or foreign stock index compiled and published by a third
party or an index based on a group of Underlying Stocks selected by the Company
solely in connection with the issuance of such Warrants, and certain information
regarding such Stock Index and the Underlying Stocks; (iv) whether such Warrants
are Put Warrants or Call Warrants; (v) the date on which the right to exercise
such Warrants commences and the date on which such right expires; (vi) the
manner in which such Warrants may be exercised; (vii) the minimum number, if
any, of such Warrants exercisable at any one time; (viii) the maximum number, if
any, of such Warrants that may, subject to the Company's election, be exercised
by all Warrantholders (or by any person or entity) on any day; (ix) any
provisions permitting a Warrantholder to condition an exercise notice on the
absence of certain specified changes in the Spot Index after the exercise date,
any provisions permitting the Company to suspend exercise of such Warrants or
redeem such Warrants based on market conditions or other circumstances and any
other special provisions relating to the exercise of such Warrants; (x) any
provisions for the automatic exercise of such Warrants other than at expiration;
(xi) any provisions permitting the Company to cancel such Warrants upon the
occurrence of certain events; (xii) the method of determining the amount payable
in connection with the exercise or cancellation of such Warrants, including the

Strike Index, the method of determining the Spot Index, the method of expressing
movements in the Stock Index as a cash amount in the currency in which the Cash
Settlement Value of such Warrants is payable, including, in the case of Warrants
relating to a Foreign Stock Index, the method of converting amounts in the
relevant foreign currency or currencies into U.S. dollars (or such other
currency in which such Warrants are payable), and any Cancellation Amount or
Minimum Expiration Value applicable to such Warrants; (xiii) the method of
providing for a substitute index or otherwise determining the amount payable in
connection with the exercise of such Warrants if the Stock Index changes or
ceases to be made available by its publisher; (xiv) the time or times at which
amounts will be payable in respect of such Warrants following exercise or
automatic exercise; (xv) any national securities exchange on which such Warrants
will be listed; (xvi) any provisions for issuing such Warrants in certificated
form from the perspective of Warrantholders; (xvii) if such Warrants are not
issued in book-entry form, the place or places at which payment of the Cash
Settlement Value, Cancellation Amount, if any, and Minimum Expiration Value, if
any, of such Warrants is to be made by the Company; and (xviii) any other terms
of such Warrants.
 
     Prospective purchasers of Warrants should be aware of special United States
federal income tax considerations applicable to instruments such as the
Warrants. The Prospectus Supplement relating to each issue of Warrants will
describe such tax considerations. The summary of United States federal income
tax considerations contained in the Prospectus Supplement will be presented for
informational purposes only, however, and will not be intended as legal or tax
advice to prospective purchasers. Prospective purchasers of Warrants are urged
to consult their own tax advisors prior to any acquisition of Warrants.
 
BOOK-ENTRY PROCEDURES AND SETTLEMENT
 
     Unless otherwise specified in the Prospectus Supplement, the Warrants
offered thereby will be issued in book-entry form from the perspective of
Warrantholders. Such Warrants will be issued in the form of a single global
certificate registered in the name of the nominee of the depository, The
Depository Trust Company ('DTC', which term, as used herein, includes any
successor depository selected by the Company).
 
     DTC is a limited-purpose trust company which was created to hold securities
for its participating organizations (the 'Participants') and to facilitate the
clearance and settlement of securities transactions between Participants in such
securities through electronic book-entry changes in accounts of its
Participants. Participants include securities brokers and dealers, banks and
trust companies, clearing corporations and certain other organizations. Access
to DTC's system is also available to others such as banks, brokers, dealers
 
                                       12
<PAGE>
and trust companies that clear through or maintain a custodial relationship with
a Participant, either directly or indirectly ('indirect participants'). Persons
who are not Participants may beneficially own securities held by DTC only
through Participants or indirect participants.
 
     DTC's nominee for all purposes will be considered the sole owner or holder
of the Warrants under the related Warrant Agreement. Owners of beneficial

interests in the global certificate will not be entitled to have Warrants
registered in their names, will not receive or be entitled to receive physical
delivery of Warrants in definitive form, and will not be considered the holders
thereof under the related Warrant Agreement.
 
     Neither the Company nor the Warrant Agent will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interest in the global certificate, or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
     A Warrantholder's ownership of a Warrant will be recorded on or through the
records of the brokerage firm or other entity that maintains such
Warrantholder's account. In turn, the total number of Warrants held by an
individual brokerage firm for its clients will be maintained on the records of
DTC in the name of such brokerage firm (or in the name of a Participant or
indirect participant that acts as agent for the Warrantholder's brokerage firm
if such firm is not a Participant or indirect participant). Therefore, a
Warrantholder must rely upon the foregoing procedures to evidence such
Warrantholder's ownership of a Warrant. Transfer of ownership of any Warrant may
be effected only through the selling Warrantholder's brokerage firm.
 
     The Cash Settlement Value and, if applicable, the Cancellation Amount or
Minimum Expiration Value payable in respect of the Warrants will be paid by the
Warrant Agent to DTC. DTC will be responsible for crediting the amount of such
payments to the accounts of the Participants or indirect participants in
accordance with its standard procedures, which currently provide for payments in
next-day funds settled through the New York Clearing House. Each Participant or
indirect participant will be responsible for disbursing such payments to the
beneficial owners of the Warrants that it represents and to each brokerage firm
for which it acts as agent. Each such brokerage firm will be responsible for
disbursing funds to the owners of the Warrants that it represents. It is
suggested that any purchaser of Warrants with accounts at more than one
brokerage firm only effect transactions in the Warrants, including exercises,
through the brokerage firm or firms that hold such purchaser's Warrants.
 
     If DTC is at any time unwilling or unable to continue as depository and a
successor depository is not appointed by the Company within 90 days, the Company
will issue Warrants in definitive form in exchange for the global certificate.
In addition, the Company may at any time determine not to have the Warrants
represented by a global certificate and, in such event, will issue Warrants in
definitive form in exchange for such global certificate. In either instance, an
owner of a beneficial interest in the global certificate will be entitled to
have Warrants equal in aggregate amount to such beneficial interest registered
in its name and will be entitled to physical delivery of such Warrants in
definitive form.
 
LISTING
 
     Unless otherwise indicated in the Prospectus Supplement, the Warrants will
be listed on a national securities exchange as specified in the Prospectus
Supplement. It is expected that such exchange will cease trading an issue of
Warrants as of the close of business on the related expiration date of such
Warrants.

 
MODIFICATION
 
     The Warrant Agreement and the terms of the related Warrants may be amended
by the Company and the Warrant Agent, without the consent of the holders of any
Warrants, for the purpose of curing any ambiguity, or of curing, correcting or
supplementing any defective or inconsistent provision contained therein,
maintaining the listing of such Warrants on any national securities exchange or
registration of such Warrants under the Exchange Act, permitting the issuance of
individual Warrant certificates to Warrantholders, reflecting the issuance by
the Company of additional Warrants of the same issue or reflecting the
appointment of a successor depository, or in any other manner which the Company
may deem necessary or desirable and which will not materially and adversely
affect the interests of the Warrantholders.
 
                                       13
<PAGE>
     The Company and the Warrant Agent also may modify or amend the Warrant
Agreement and the terms of the related Warrants, with the consent of the holders
of not less than a majority in number of the then outstanding Warrants affected
by such modification or amendment, for any purpose, provided that no such
modification or amendment that decreases the Strike Index (in the case of Put
Warrants) or increases the Strike Index (in the case of Call Warrants),
otherwise changes the determination of the Cash Settlement Value or Cancellation
Amount, if any, or Minimum Expiration Value, if any, of the Warrants (or any
aspects of such determination) so as to reduce the amount receivable upon
exercise, cancellation or expiration, shortens the period of time during which
the Warrants may be exercised, decreases the Minimum Expiration Value, if any,
or otherwise materially and adversely affects the exercise rights of the holders
of the Warrants or reduces the percentage of the number of outstanding Warrants
the consent of whose holders is required for modification or amendment of the
Warrant Agreement or the terms of the related Warrants, may be made without the
consent of each Warrantholder affected thereby.
 
MERGER, CONSOLIDATION, SALE OR OTHER DISPOSITIONS
 
     If at any time there is a merger or consolidation involving the Company or
a sale, transfer, conveyance or other disposition of all or substantially all of
the assets of the Company, then the successor or assuming corporation will
succeed to and be substituted for the Company under the Warrant Agreement and
the related Warrants, with the same effect as if it had been named in such
Warrant Agreement and Warrants as the Company. The Company will thereupon be
relieved of any further obligation under such Warrant Agreement and Warrants
and, in the event of any such sale, transfer, conveyance (other than by way of
lease) or other disposition, the Company as the predecessor corporation may
thereupon or at any time thereafter be dissolved, wound up or liquidated.
 
ENFORCEABILITY OF RIGHTS BY WARRANTHOLDERS
 
     Any Warrantholder may, without the consent of the Warrant Agent or any
other Warrantholder, enforce by appropriate legal action on his own behalf his
right to exercise, and to receive payment for, his Warrants.
 
                              PLAN OF DISTRIBUTION

 
     The Company may sell the Warrants in any of three ways: (i) through
underwriters; (ii) directly to one or more purchasers; or (iii) through agents.
The Prospectus Supplement with respect to the Warrants being offered thereby
sets forth the terms of the offering of such Warrants, including the names of
any underwriters, the purchase price of such Warrants and the proceeds to the
Company from such sale, any underwriting discounts and other items constituting
underwriters' compensation, any initial public offering price, any discounts or
concessions allowed or reallowed or paid to dealers and any national securities
exchange on which such Warrants will be listed. Only underwriters so named in
the Prospectus Supplement are deemed to be underwriters in connection with the
Warrants offered thereby.
 
     If underwriters are used in the sale, the Warrants will be acquired by the
underwriters for their own account and may be resold from time to time in one or
more transactions, including negotiated transactions, at a fixed public offering
price or at varying prices determined at the time of sale. The Warrants may be
offered to the public either through underwriting syndicates represented by
managing underwriters or by underwriters without a syndicate. Such managing
underwriters or underwriters may include PaineWebber. Unless otherwise set forth
in the Prospectus Supplement, the obligations of the underwriters to purchase
such Warrants will be subject to certain conditions precedent, and the
underwriters will be obligated to purchase all the Warrants offered by the
Prospectus Supplement if any of such Warrants are purchased. Any initial public
offering price and any discounts or concessions allowed or reallowed or paid to
dealers may be changed from time to time.

     Warrants may also be sold directly by the Company or through agents
designated by the Company from time to time. Any agents involved in the offer or
sale of the Warrants will be named, and any commissions payable by the Company
to such agents will be set forth, in the Prospectus Supplement. Such agents may
include PaineWebber. Unless otherwise indicated in the Prospectus Supplement,
any such agent is acting on a best-efforts basis for the period of its
appointment.
 
                                       14
<PAGE>
     The Warrants, including additional Warrants of a previous issue, may be
sold on any national securities exchange on which the Warrants are listed.
 
     Agents and underwriters may be entitled under agreements entered into with
the Company to indemnification by the Company against certain civil liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which the agents or underwriters may be required to make in respect
thereof. Agents and underwriters may be customers of, engage in transactions
with, or perform services for, the Company or its affiliates in the ordinary
course of business.
 
     PaineWebber expects to offer and sell previously issued Warrants from time
to time in the course of its business as a broker-dealer. PaineWebber may act as
principal or agent in such transactions. The Warrants may be offered or sold in
such transactions on any national securities exchange on which the Warrants are
listed. Sales will be made at prices related to prevailing prices at the time of
sale.

 
     PaineWebber is a wholly owned subsidiary of the Company. The participation
of PaineWebber in the offer and sale of the Warrants will comply with the
requirements of Schedule E of the By-Laws of the NASD regarding underwriting
securities of an affiliate. Under the provisions of Schedule E, when a NASD
member such as PaineWebber distributes warrants of an affiliate, the price of
the warrants can be no higher than that recommended by a 'qualified independent
underwriter', as such term is defined in Schedule E, meeting certain standards.
In accordance with such requirement, PaineWebber will select a 'qualified
independent underwriter' in connection with each issue of Warrants to conduct
due diligence and recommend a price for such Warrants in compliance with the
requirements of Schedule E.
 
                              ERISA CONSIDERATIONS
 
     The Employee Retirement Income Security Act of 1974, as amended ('ERISA'),
imposes certain restrictions on employee benefit plans ('Plans') which are
subject to ERISA, and on those persons who are fiduciaries with respect to such
Plans. In accordance with ERISA's general fiduciary requirements, a fiduciary
with respect to any such Plan who is considering the purchase of Warrants on
behalf of such Plan should determine whether such purchase is permitted under
the governing Plan documents, is prudent and is appropriate for the Plan in view
of its overall investment policy and the composition and diversification of its
portfolio. See 'Risk Factors'. Other provisions of ERISA and section 4975 of the
Internal Revenue Code of 1986, as amended (the 'Code'), prohibit certain
transactions involving the assets of a Plan and persons who have certain
specified relationships to the Plan ('parties in interest' within the meaning of
ERISA or 'disqualified persons' within the meaning of section 4975 of the Code).
Thus, a Plan fiduciary considering the purchase of Warrants should consider
whether such a purchase might constitute or result in a prohibited transaction
under ERISA or section 4975 of the Code.
 
     The Company and PaineWebber may each be considered a 'party in interest' or
a 'disqualified person' with respect to many Plans. The purchase of Warrants by
a Plan that is subject to the fiduciary responsibility provisions of ERISA or
the prohibited transaction provisions of section 4975 of the Code (including
individual retirement arrangements and other plans described in section
4975(e)(1) of the Code) and with respect to which the Company or PaineWebber or
any of their affiliates is a service provider (or otherwise is a 'party in
interest' or 'disqualified person') may constitute or result in a non-exempt
prohibited transaction under ERISA or section 4975 of the Code, unless such
Warrants are acquired pursuant to and in accordance with an applicable
exemption, such as Prohibited Transaction Class Exemption ('PTCE') 90-1 (an
exemption for certain transactions involving insurance company pooled separate
accounts), PTCE 84-14 (an exemption for certain transactions determined by an
independent qualified professional asset manager) or PTCE 91-38 (an exemption
for certain transactions involving bank collective investment funds). Any
pension or other employee benefit plan proposing to acquire any Warrants should
consult with its counsel.
