  redemption amount). Fractional shares will be paid in cash. The number of
  shares received for each $1,000 invested will be calculated by dividing the
  initial price per share of $39.00 into $1,000. The stock redemption amount and

  splits or other corporate actions.

Prospectus Supplement Summary

The following is a summary of the terms of the GOALs, as well as considerations
relating to purchasing a GOAL. All of the information set forth in this section
is qualified in its entirety by the more detailed explanations set forth
elsewhere in this prospectus supplement and the accompanying prospectus.

SUMMARY OF TERMS

The GOALs are issued by UBS AG with 19.5% annual coupon paid semi-annually and
repayment at maturity linked to the performance of Cisco Systems, Inc. common
stock. If the closing price of Cisco Systems, Inc. common stock on July 18, 2002
(the determination date) is at or above the initial price per share of $39.00
(strike price), you will receive a cash payment at maturity equal to the
principal amount of the GOALs you hold. If, however, the closing price of Cisco
Systems, Inc. common stock is lower than the initial price per share of $39.00,
you will receive 25.641 shares of common stock of Cisco Systems, Inc. for each
$1,000 principal amount of the GOALs you hold. Fractional shares will be paid in
cash. The number of shares received for each $1,000 invested was calculated by
dividing the initial price per share of $39.00 into $1,000. The stock redemption
amount and the initial price per share of $39.00 (strike price) may change due
to stock splits or other corporate actions.

WHO SHOULD CONSIDER PURCHASING GOALs?

Investors who seek high current income and who are willing to accept the risk of
owning equities in general and the common stock of Cisco Systems, Inc. in
particular. These are investors who anticipate that the common stock of Cisco
Systems, Inc. will either remain unchanged or appreciate or depreciate only to a
limited degree during the period of the GOALs.

Investors who are unwilling to own the common stock of Cisco Systems, Inc. or
who seek the lower risk (and accept the lower returns) of money market, treasury
or agency bonds or other traditional fixed income instruments should not
purchase a GOAL.

SELECTED PURCHASE CONSIDERATIONS

- ENHANCED COUPON.  The GOALs provide a higher coupon than would generally be
  paid on bonds of an issuer with a comparable credit rating.

- ENHANCED POTENTIAL YIELD.  In the event that the stock price of Cisco Systems,
  Inc. remains relatively unchanged, GOALs may provide enhanced performance to
  investors compared with owning Cisco Systems, Inc. common stock.

- DIVERSIFICATION.  The GOALs linked to the common stock of Cisco Systems, Inc.
  may help to broaden an existing portfolio mix of stocks, bonds, mutual funds
  and cash.

- EXCHANGE LISTING.  The GOALs have been approved for listing on the American
  Stock Exchange. However, there can be no guarantee of liquidity in the
  secondary market.

- U.S. SETTLEMENT.  The GOALs are traded and settled in the U.S. market.

SELECTED RISK CONSIDERATIONS

An investment in GOALs involves significant risks. Some of these risks are
summarized here, but we urge you to read the more detailed explanation of risks
in the "Risk Factors" section of this Prospectus Supplement, beginning on page
S-5.

- MARKET RISKS.  GOALs are exposed to the same downside price risk as the common
  stock of Cisco Systems, Inc. and do not provide protection of principal. GOALs
  do not have the same price

                                                                            S- 3
<PAGE>   4

  appreciation potential as the underlying stock. At maturity, the value of the
  GOALs cannot appreciate above their principal amount.

- LIQUIDITY.  There may be little or no secondary market for the GOALs. While
  UBS Warburg LLC and other affiliates of UBS AG intend to make a market in the
  GOALs, if a holder needs to liquidate GOALs prior to maturity, he or she may
  have to sell the GOALs at a substantial discount from the principal amount if
  the market price of the common stock of Cisco Systems, Inc. is at, below, or
  not sufficiently above the initial market price. You should be willing to hold
  your GOALs until maturity.

CONSIDERATIONS RELATING TO TAXATION

The terms of GOALs require (in the absence of an administrative or judicial
ruling to the contrary) that you treat your GOALs for tax purposes as consisting
of two components: (1) a non-contingent debt instrument issued by us and (2) a
put option on the common stock of Cisco Systems, Inc. which you sold to us.
Under this tax treatment, the interest paid is divided into two components for
tax purposes. The interest on the debt component is taxed as ordinary income in
the year it is received or accrued depending on your method of accounting for
tax purposes. The option component is generally not taxed until sale or
maturity. At maturity, the option component is taxed as a short term capital
gain if the Cisco Systems, Inc. stock price is at or above the initial stock
price. If the stock has declined in value and the final payment on the GOALs is
paid in shares of Cisco Systems, Inc. common stock, the option component reduces
the cost basis of the stock received.

The United States federal income tax consequences of your investment in GOALs is
uncertain. In the opinion of our counsel, Sullivan & Cromwell, it is reasonable
to treat your GOALs as described above, but it would also be reasonable to treat
your GOALs as a single contingent debt instrument subject to the special tax
rules governing contingent debt instruments. BECAUSE OF THIS UNCERTAINTY, WE
URGE YOU TO CONSULT YOUR TAX ADVISOR AS TO THE TAX CONSEQUENCES OF YOUR
INVESTMENT IN GOALS. For a more complete discussion of the United States federal
income tax consequences of your investment in GOALs, including tax consequences
applicable to non-United States persons and persons who purchase GOALs in the
secondary market, please see the discussion under "Supplemental Tax
Considerations -- Supplemental U.S. Tax Considerations."

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

Risk Factors

The GOALs are not secured debt and are riskier than ordinary unsecured debt
securities. The return on the GOALs is linked to the performance of Cisco
Systems, Inc. common stock and there is no guaranteed return of principal.
Investing in the GOALs is NOT equivalent to investing directly in Cisco Systems,
Inc. common stock. This section describes the most significant risks relating to
the GOALs. WE URGE YOU TO READ THE FOLLOWING INFORMATION ABOUT THESE RISKS,
TOGETHER WITH THE OTHER INFORMATION IN THIS PROSPECTUS SUPPLEMENT AND THE
ACCOMPANYING PROSPECTUS, BEFORE INVESTING IN THE GOALs.

THE GOALs ARE NOT ORDINARY SENIOR NOTES: THERE IS NO GUARANTEED RETURN OF
PRINCIPAL

The GOALs combine features of equity and debt. The terms of the GOALs differ
from those of ordinary debt securities in that we will NOT pay you a fixed
amount at maturity if the market price of Cisco Systems, Inc. common stock is
less than $39.00 on the determination date. In that event, our payment to you at
maturity will be 25.641 shares of Cisco Systems, Inc. common stock per $1,000
face amount of GOALs. THEREFORE, IF THE MARKET PRICE OF CISCO SYSTEMS, INC.
COMMON STOCK ON THE DETERMINATION DATE IS LESS THAN $39.00, WE WILL PAY YOU AN
AMOUNT OF CISCO SYSTEMS, INC. COMMON STOCK WITH A MARKET VALUE LESS THAN THE
PRINCIPAL AMOUNT OF THE GOALs. ACCORDINGLY, YOU CAN LOSE SOME OR ALL OF THE
AMOUNT THAT YOU INVEST IN THE GOALs. See "-- Sensitivity Analysis" below.

THE VALUE OF THE GOALs CANNOT EXCEED THE STATED PRINCIPAL AMOUNT AT MATURITY

The value of the principal amount paid or shares of Cisco Systems, Inc.
exchanged at the maturity date will NOT exceed the principal amount of the
GOALs. If the market price of Cisco Systems, Inc. common stock on the
determination date is equal to or exceeds $39.00, you will not receive common
stock or any other asset with the value of the common stock. Instead, you will
receive the principal amount of the GOALs. UNDER NO CIRCUMSTANCES WILL YOU
RECEIVE A PRINCIPAL AMOUNT AT MATURITY GREATER THAN THE PRINCIPAL AMOUNT OF THE
GOALs THAT YOU HOLD AT THAT TIME.

YOU MAY NOT HAVE AN ACTIVE TRADING MARKET IN THE GOALs

You should be willing to hold your GOALs until the maturity date. There may be
little or no secondary market for the GOALs. Although the GOALs have been
approved for listing on the American Stock Exchange, it is not possible to
predict whether a secondary market will develop for the GOALs. Even if a
secondary market for the GOALs develops, it may not provide significant
liquidity or trade at prices advantageous to you. UBS Warburg LLC and other
affiliates of UBS AG currently intend to make a market for the GOALs but they
are NOT required to do so. UBS Warburg LLC or any other affiliate of UBS AG may
stop making a market in the GOALs at any time.

THE MARKET PRICE OF THE GOALs WILL BE INFLUENCED BY UNPREDICTABLE FACTORS

The value of the GOALs may move up or down between the date you purchase them
and the determination date when we determine the amount to be paid to holders of
the GOALs on the maturity date. Therefore, you may sustain a significant loss if
you sell the GOALs in the secondary market during that time. Several factors,
many of which are beyond our control, will influence the value of the GOALs. WE
EXPECT THAT GENERALLY THE MARKET PRICE OF CISCO SYSTEMS, INC. COMMON STOCK ON
ANY DAY WILL AFFECT THE VALUE OF THE GOALs MORE THAN ANY OTHER SINGLE FACTOR.
Other factors that may influence the value of the GOALs include:

- the frequency and magnitude of changes in price of Cisco Systems, Inc. common
  stock (volatility)

- the dividend rate on Cisco Systems, Inc. common stock (while not paid to
  holders of the GOALs, dividend payments, if any, on the common stock of Cisco
  Systems, Inc. may have an influence on the market price of the common stock
  and therefore on the GOALs)

                                                                            S- 5
<PAGE>   6
RISK FACTORS
--------------------------------------------------------------------------------

- economic, financial, political and regulatory or judicial events that affect
  stock markets generally which may also affect the market price of Cisco
  Systems, Inc. common stock

- interest and yield rates in the market

- the time remaining to the maturity of the GOALs

- the creditworthiness of UBS AG

While it is possible that the GOALs could trade above their principal amount
prior to maturity, the likelihood of such an increase is limited because the
amount payable at maturity will not exceed the principal amount of the GOALs and
by the market factors set forth above. Even if the GOALs did trade above their
principal amount prior to maturity, the only way to realize such a market
premium would be to sell your GOALs in a secondary market transaction, if such a
transaction were available. MOREOVER, IF YOU SELL YOUR GOALs PRIOR TO MATURITY,
YOU MAY HAVE TO SELL THEM AT A SUBSTANTIAL DISCOUNT FROM THEIR PRINCIPAL AMOUNT
IF THE MARKET PRICE OF CISCO SYSTEMS, INC. COMMON STOCK IS AT, BELOW, OR NOT
SUFFICIENTLY ABOVE THE INITIAL PRICE PER SHARE.

IF THE MARKET PRICE OF CISCO SYSTEMS, INC. COMMON STOCK CHANGES, THE MARKET
VALUE OF YOUR GOALs MAY NOT CHANGE IN THE SAME MANNER

Owning the GOALs is not the same as owning common stock of the Cisco Systems,
Inc. Accordingly, the market value of your GOALs may not have a direct
relationship with the market price of Cisco Systems, Inc. common stock and
changes in the market price of Cisco Systems, Inc. common stock may not result
in a comparable change in the market value of your GOALs. If the price of the
common stock of Cisco Systems, Inc. increases above the initial price per share
of $39.00, the market value of the GOALs may not increase. It is also possible
for the price of the common stock of Cisco Systems, Inc. to increase while the
market price of the GOALs declines.

TRADING AND OTHER TRANSACTIONS BY UBS AG OR ITS AFFILIATES IN THE COMMON STOCK
OF CISCO SYSTEMS, INC., OR OPTIONS AND OTHER DERIVATIVE PRODUCTS ON THE COMMON
STOCK OF CISCO SYSTEMS, INC. MAY IMPAIR THE VALUE OF THE GOALs

As described below under "Use of Proceeds and Hedging," we or one or more
affiliates may hedge our obligations under the GOALs by purchasing Cisco
Systems, Inc. common stock, options on that stock or other derivative
instruments with returns linked to or related to changes in the value of Cisco
Systems, Inc. common stock and may adjust these hedges by, among other things,
purchasing or selling Cisco Systems, Inc. common stock, options or other
derivative instruments at any time and from time to time. Although they are not
expected to, any of these hedging activities may adversely affect the price of
Cisco Systems, Inc. common stock and, therefore, the value of the GOALs. It is
possible that we or one or more of our affiliates could receive substantial
returns from these hedging activities while the value of the GOALs may decline.

We or one or more of our affiliates may also engage in trading in Cisco Systems,
Inc. common stock and other investments relating to Cisco Systems, Inc. on a
regular basis as part of our general broker-dealer and other businesses, for
proprietary accounts, for other accounts under management or to facilitate
transactions for customers, including block transactions. Any of these
activities could adversely affect the price of Cisco Systems, Inc. common stock
and, therefore, the value of the GOALs. We or one or more of our affiliates may
also issue or underwrite other securities or financial or derivative instruments
with returns linked or related to changes in the value of Cisco Systems, Inc.
common stock. By introducing competing products into the marketplace in this
manner, we or one or more of our affiliates could adversely affect the value of
the GOALs.

RISK FACTORS
--------------------------------------------------------------------------------

The indenture governing the GOALs does not contain any restriction on our
ability or the ability of any of our affiliates to sell, pledge or otherwise
convey all or any portion of Cisco Systems, Inc. common stock acquired by us or
our affiliates. Neither we nor any of our affiliates will pledge or otherwise
hold common stock of Cisco Systems, Inc. for the benefit of holders of the GOALs
in order to enable the holders to exchange their GOALs for common stock of Cisco
Systems, Inc. under any circumstances. Consequently, in the event of a
bankruptcy, insolvency or liquidation involving us, any Cisco Systems, Inc.
common stock that we own will be subject to the claims of our creditors
generally and will not be available specifically for the benefit of the holders
of the GOALs.

UBS AG'S BUSINESS ACTIVITIES MAY CREATE CONFLICTS OF INTEREST BETWEEN YOU AND US

We and one or more of our affiliates may, at present or in the future, engage in
business with Cisco Systems, Inc. and its competitors, including making loans to
or equity investments in Cisco Systems, Inc. and its competitors or providing
either with investment banking, asset management or other advisory services,
including merger and acquisition advisory services. These activities may present
a conflict between our or our affiliates' obligations and your interests as a
holder of the GOALs. Moreover, we or one or more of our affiliates have
published and may in the future publish research reports on Cisco Systems, Inc.
This research is modified from time to time without notice and may express
opinions or provide recommendations that are inconsistent with purchasing or
holding the GOALs. Any of these activities may affect the price of the Cisco
Systems, Inc. common stock and, therefore, the value of the GOALs.

YOU HAVE NO SHAREHOLDER RIGHTS IN THE COMMON STOCK OF CISCO SYSTEMS, INC.

As an owner of GOALs, you will not have voting rights or rights to receive
dividends or other distributions or any other rights that holders of common
stock of Cisco Systems, Inc. would have.

UBS AG AND ITS AFFILIATES HAVE NO AFFILIATION WITH CISCO SYSTEMS, INC., AND ARE
NOT RESPONSIBLE FOR CISCO SYSTEMS, INC.'S PUBLIC DISCLOSURE OF INFORMATION,
WHETHER CONTAINED IN SEC FILINGS OR OTHERWISE

UBS AG and its affiliates are not affiliated with Cisco Systems, Inc. and have
no ability to control or predict the actions of Cisco Systems, Inc., including
any corporate actions of the type that would require the calculation agent to
adjust the payout to you at maturity, and have no ability to control the public
disclosure of these corporate actions or any other events or circumstances
affecting Cisco Systems, Inc. CISCO SYSTEMS, INC. IS NOT INVOLVED IN THE OFFER
OF THE GOALs IN ANY WAY AND HAS NO OBLIGATION TO CONSIDER YOUR INTEREST AS AN
OWNER OF GOALs IN TAKING ANY CORPORATE ACTIONS THAT MIGHT AFFECT THE VALUE OF
YOUR GOALs. CISCO SYSTEMS, INC. MAY TAKE ACTIONS THAT WILL ADVERSELY AFFECT THE
VALUE OF YOUR GOALs. None of the money you pay for the GOALs will go to Cisco
Systems, Inc.

Neither we nor any of our affiliates assumes any responsibility for the adequacy
or accuracy of the information about Cisco Systems, Inc. contained in this
prospectus supplement or in any of Cisco Systems, Inc.'s publicly available
filings. YOU, AS AN INVESTOR IN THE GOALs, SHOULD MAKE YOUR OWN INVESTIGATION
INTO CISCO SYSTEMS, INC.

YOU HAVE LIMITED ANTIDILUTION PROTECTION

UBS Warburg LLC, as calculation agent for the GOALs, will adjust the amount
payable at maturity, by adjusting the initial price per share (strike price) and
the stock redemption amount for certain events affecting Cisco Systems, Inc.
common stock, such as stock splits and stock dividends, and certain other
corporate actions involving Cisco Systems, Inc., such as mergers. However, the
calculation agent is not required to make an adjustment for every corporate
event that can affect the

                                                                            S- 7
<PAGE>   8
RISK FACTORS
--------------------------------------------------------------------------------

Cisco Systems, Inc. common stock. For example, the calculation agent is not
required to make any adjustments if Cisco Systems, Inc. or anyone else makes a
partial tender or partial exchange offer for the Cisco Systems, Inc. common
stock. IF AN EVENT OCCURS THAT DOES NOT REQUIRE THE CALCULATION AGENT TO ADJUST
THE AMOUNT OF CISCO SYSTEMS, INC. COMMON STOCK PAYABLE AT MATURITY, THE MARKET
PRICE OF THE GOALs AND THE PRINCIPAL AMOUNT OF THE GOALs PAYABLE AT THE MATURITY
DATE MAY BE MATERIALLY AND ADVERSELY AFFECTED. You should refer to "Role of the
Calculation Agent" below for a description of the items that the calculation
agent is responsible to determine.

THERE ARE POTENTIAL CONFLICTS OF INTEREST BETWEEN YOU AND THE CALCULATION AGENT

As calculation agent for the GOALs, UBS Warburg LLC will calculate the payout to
you at maturity of the GOALs. UBS Warburg LLC and other affiliates of UBS AG may
also carry out hedging activities related to the GOALs or to other instruments,
including trading in Cisco Systems, Inc. common stock, as well as in other
instruments related to Cisco Systems, Inc. common stock. UBS Warburg LLC also
trades Cisco Systems, Inc. common stock and other financial instruments relating
to Cisco Systems, Inc. on a regular basis as part of its general broker dealer
and other businesses. Any of these activities could influence UBS Warburg LLC's
determination of adjustments made to the GOALs and any such trading activity
could potentially affect the price of Cisco Systems, Inc. common stock and,
accordingly could affect your payout on the GOALs.

WE CAN POSTPONE THE MATURITY DATE IF A MARKET DISRUPTION EVENT OCCURS

If the calculation agent determines that, on the determination date, a market
disruption event has occurred or is continuing, the determination date will be
postponed until the first business day on which no market disruption event
occurs or is continuing. As a result, the maturity date for the GOALs will also
be postponed, although not by more than five business days. Thus, you may not
receive the payment -- or, if the GOALs are to be exchanged, any delivery of
Cisco Systems, Inc. common stock -- that we are obligated to make on the
maturity date until after the originally scheduled maturity date.

SIGNIFICANT ASPECTS OF THE TAX TREATMENT OF THE GOALs ARE UNCERTAIN

You should also consider the tax consequences of investing in the GOALs.
Significant aspects of the tax treatment of the GOALs are uncertain. We do not
plan to request a ruling from the Internal Revenue Service or from any Swiss
authorities regarding the tax treatment of the GOALs, and the IRS or a court may
not agree with the tax treatment described in this prospectus supplement. Please
read carefully the section entitled "Considerations Relating to Taxation" in the
summary section above, "Supplemental Tax Considerations" below, and the sections
"U.S. Tax Considerations" and "Tax Considerations Under the Laws of Switzerland"
in the accompanying prospectus. YOU SHOULD CONSULT YOUR TAX ADVISOR ABOUT YOUR
OWN TAX SITUATION.

HISTORICAL PERFORMANCE OF CISCO SYSTEMS, INC.
--------------------------------------------------------------------------------

WE OBTAINED THE INFORMATION ABOUT CISCO SYSTEMS, INC. IN THIS PROSPECTUS
SUPPLEMENT FROM CISCO SYSTEMS, INC. PUBLIC FILINGS

This prospectus supplement relates only to the GOALs and does not relate to the
common stock of Cisco Systems, Inc. We have derived all information about Cisco
Systems, Inc. in this prospectus supplement from the publicly available
documents referred to in the preceding subsection. We have not participated in
the preparation of any of those documents or made any "due diligence"
investigation or any inquiry of Cisco Systems, Inc. in connection with the

available documents or any other publicly available information about Cisco

Cisco Systems, Inc. has disclosed all events occurring before the date of this
prospectus supplement -- including events that would affect the accuracy or
completeness of the publicly available documents referred to above, the trading
price of the underlying stock and, therefore, the exchange rate the calculation
agent uses to determine the number of underlying shares you will receive if the
price at maturity is below $39.00 per share. Subsequent disclosure of any events
of this kind or the disclosure of or failure to disclose material future events
concerning Cisco Systems, Inc. could affect the value you will receive at
maturity and, therefore, the market value of the GOALs.

NEITHER WE NOR ANY OF OUR AFFILIATES MAKE ANY REPRESENTATION TO YOU AS TO THE
PERFORMANCE OF THE COMMON STOCK OF CISCO SYSTEMS, INC.

We or any of our affiliates may currently or from time to time engage in

of that business, we or any of our affiliates may acquire non-public information
about Cisco Systems, Inc. and, in addition, one or more of our affiliates may
publish research reports about Cisco Systems, Inc. NONETHELESS, AS AN INVESTOR
IN A GOAL, YOU SHOULD UNDERTAKE SUCH INDEPENDENT INVESTIGATION OF CISCO SYSTEMS,
INC. AS IN YOUR JUDGMENT IS APPROPRIATE TO MAKE AN INFORMED DECISION WITH
RESPECT TO AN INVESTMENT IN A GOAL.

Sensitivity Analysis:    Comparison of Total Return of the GOALs at Maturity
Against Owning the Underlying Stock

The total return at maturity of owning the GOALs compared to the common stock of
Cisco Systems, Inc. is driven by a number of factors including the price of the
underlying stock at maturity, the coupon level of the GOALs, dividends paid on
the stock and the reinvestment rate. The total return prior to maturity of
owning the GOALs is driven by a number of factors. See "Valuation of the GOALs"
on S-13. In the graph and table below, we compare the total return of owning the
underlying stock to the total return of owning the GOALs at maturity based on
the assumptions outlined below. The actual initial price and GOALs coupon will
be set on the trade date. The information in the graph and table is based on
hypothetical market values for the underlying stock and your GOAL. We cannot
predict the market price of the underlying stock or the market value of the
GOALs, nor can we predict the relationship between the two. Moreover, the
assumptions we have made in connection with the illustration set forth below may
not reflect actual events. Consequently, the total return that an investor in
the GOALs would actually achieve, as well as how that return would compare to
the total return that an investor in Cisco Systems, Inc. common stock would
actually achieve, may be very different from the information reflected in the
graph and table.

Assumptions:

-  Initial stock price of underlying stock: $39.00 per share

-  Annual GOALs coupon: 19.5%

-  Annual dividend yield: 0%

-  Reinvestment rate for GOALs coupon and stock dividends: 0%

Valuation of the GOALs

AT MATURITY.  As described above, a $1,000 investment in the GOALS will be worth
$1,000 if the common stock of Cisco Systems, Inc. is equal to or above the
initial stock price of $39.00. If the stock price has declined, however, you
will receive a number of shares of the underlying stock. The value of your
investment, therefore will equal the value of the shares you receive at
maturity, which could be substantially less than the value of the original
investment.

PRIOR TO MATURITY.  The value of the GOALs will be affected by a number of
interrelated factors including, but not limited to, supply and demand, the level
of the underlying stock, the volatility and dividend level of the stock, the
time remaining to maturity, the level of interest rates and other economic
conditions, as well as the perceived creditworthiness of the issuer. Generally,
the value of the GOALs will tend to rise with the increase in the stock price
and falling volatility, although this increase in value is limited because the
value at maturity cannot exceed the principal amount of the GOALs. The value of
the GOALs will generally decline as the stock price declines, stock volatility
increases, and the dividend level of the stock rises. In addition, rising
interest rates will on balance hurt the value of the GOALs. You should
understand that the value of the GOALs is driven by a range of interrelated
factors and that while the price of the stock is an important variable, it
cannot be used as the sole measure to approximate value of this investment. You
should not use any single variable to approximate the value of this investment.

                                                                           S- 13

Owners of beneficial interests in the GOALs should read the section entitled
"Legal Ownership of Notes" in the accompanying prospectus.

The GOALs are part of a series of debt securities entitled "Medium Term Notes,
Series A" that we may issue under the indenture from time to time. This
prospectus supplement summarizes specific financial and other terms that apply
to the GOALs. Terms that apply generally to all Medium Term Notes, Series A are
described in "Description of Notes We May Offer" in the accompanying prospectus.
The terms described here supplement those described in the accompanying
prospectus and, if the terms described here are inconsistent with those
described there, the terms described here are controlling.

In this prospectus supplement, when we refer to the underlying or index stock,
we mean the common stock of Cisco Systems, Inc. and when we refer to the Index
Stock Issuer, we mean that company, except as noted below under "--Antidilution
Adjustments--Reorganization Events--Distribution Property".

Please note that the information about the trade date, settlement date, price to
public and net proceeds to UBS AG on the front cover relates only to the initial
sale of the GOALs. If you have purchased GOALs in a market-making transaction
after the initial sale, information about the price and date of sale to you will
be provided in a separate confirmation of sale.

We describe the terms of the GOALs in more detail below.

INTEREST/OPTION PREMIUM

The GOALs bear interest from January 23, 2001 at the rate of 19.5% per annum,
payable semi-annually in arrears on each January 23 and July 23, which annual
interest amount shall be composed of (a) a coupon representing interest at a
rate of 5.2% per annum and (b) a coupon representing an option premium of 14.3%
per annum.

PAYMENT AT MATURITY

On the maturity date, we will pay as principal to the holders of the GOALs

-  if the closing price of the common stock of Cisco Systems, Inc. is equal to
   or above the initial price of $39.00 per share on the determination date
   (subject to antidilution adjustment), cash in an amount equal to 100% of the
   outstanding principal amount of the GOALs; or

-  if the closing price of the common stock of Cisco Systems, Inc. is less than
   the initial price of $39.00 per share on the determination date (subject to
   antidilution adjustment), 25.641 shares for each nominal amount $1,000 of
   GOALs (the stock redemption amount). Fractional shares will be paid in cash.

STOCK REDEMPTION AMOUNT

If the payment at maturity is in shares of Cisco Systems, Inc., the number of
shares of common stock of Cisco Systems, Inc. received for each $1,000 invested
is referred to as the stock redemption amount. The stock redemption amount is
calculated by dividing $1,000 by the initial price of the shares which

S- 14
<PAGE>   15
SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

is set on the trade date. The stock redemption amount and the initial price
(strike price) may change due to stock splits or other corporate actions. See
"--Antidilution Adjustments" below.

The closing price on the trade date is referred to here as the initial price or
the strike price.

MATURITY DATE

The maturity date will be July 23, 2002 unless that day is not a business day,
in which case the maturity date will be the next following business day. If the
third business day before this applicable day is not the determination date
referred to below, however, then the maturity date will be the third business
day following the determination date, although the maturity date will never be
later than the third business day after July 25, 2002 or, if July 25, 2002 is
not a business day, later than the fourth business day after July 25, 2002. The
calculation agent may postpone the determination date--and therefore the
maturity date--if a market disruption event occurs or is continuing on a day
that would otherwise be the determination date. We describe market disruption
events below under "--Special Calculation Provisions".

REGULAR RECORD DATES FOR INTEREST

The regular record date relating to an interest payment date for the GOALs will
be the day next preceding that interest payment date, whether or not the record
date is a business day. For the purpose of determining the Holder at the close
of business on a regular record date when business is not being conducted, the
close of business will mean 5:00 p.m., New York City time, on that day.

DETERMINATION DATE

The determination date will be the third business day prior to July 23, 2002,
unless the calculation agent determines that a market disruption event occurs or
is continuing on that day. In that event, the determination date will be the
first following business day on which the calculation agent determines that a
market disruption event does not occur and is not continuing. In no event,
however, will the determination date be later than July 25, 2002 or, if July 25,
2002 is not a business day, later than the first business day after July 25,
2002.

MARKET DISRUPTION EVENT

As described above, the calculation agent will use the closing price of Cisco
Systems, Inc. common stock on the determination date to determine whether we
will pay the outstanding principal amount of the GOALs or exchange the GOALs for
shares of common stock of Cisco Systems, Inc. on the maturity date. If a market
disruption event occurs or is continuing on a day that would otherwise be a
determination date, then the calculation agent will instead use the closing
price on the first business day after that day on which no market disruption
event occurs or is continuing. In no event, however, will the determination date
be postponed by more than five business days.

If the determination date is postponed to the last possible day, but a market
disruption event occurs or is continuing on that day, that day will nevertheless
be the determination date. If the market price of Cisco Systems, Inc. is not
available on the last possible determination date either because of a market
disruption event or for any other reason, the calculation agent will make a good
faith estimate of the exchange-traded price for the common stock of Cisco
Systems, Inc. that would have prevailed in the absence of the market disruption
event or such other reason on the last possible determination date.

                                                                           S- 15
<PAGE>   16
SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

Any of the following will be a market disruption event

-  a suspension, absence or material limitation of trading in the index stock in
   its primary market for more than two hours of trading or during the one-half
   hour before the close of trading in that market, as determined by the
   calculation agent in its sole discretion

-  a suspension, absence of trading or material limitation of trading in option
   contracts relating to the index stock, if available, in the primary market
   for those contracts for more than two hours of trading or during the one-half
   hour before the close of trading in that market, as determined by the
   calculation agent in its sole discretion

-  the index stock does not trade on the Nasdaq National Market, or the primary
   market for Cisco Systems, Inc., as determined by the calculation agent in its
   sole discretion

and, in any of these events, the calculation agent determines in its sole
discretion that the event materially interferes with our ability or the ability
of any of our affiliates to unwind all or a material portion of a hedge with
respect to the GOALs that we or our affiliates have effected or may effect as
described below under "Use of Proceeds and Hedging."

The following events will not be market disruption events

-  a limitation on the hours or numbers of days of trading, but only if the
   limitation results from an announced change in the regular business hours of
   the relevant market

-  a decision to permanently discontinue trading in the option contracts
   relating to the index stock.

For this purpose, an "absence of trading" in the primary securities market on
which option contracts related to the index stock are traded will not include
any time when that market is itself closed for trading under ordinary
circumstances.

In contrast, a suspension or limitation of trading in option contracts related
to the index stock, if available, in the primary market for those contracts, by
reason of any of:

-  a price change exceeding limits set by that market

-  an imbalance of orders relating to those contracts

-  a disparity in bid and ask quotes relating to those contracts

will constitute a suspension or material limitation of trading in option
contracts related to the index stock in the primary market for those contracts.

ANTIDILUTION ADJUSTMENTS

The calculation agent will adjust the strike price or the stock redemption
amount or both as described below, if an event described below occurs and the
calculation agent determines that such event has a diluting or concentrative
effect on the theoretical value of the common stock of Cisco Systems, Inc. The
adjustments described below do not cover all events that could affect the value
of the GOALs. We describe the risks relating to dilution above under "Risk
Factors--You have limited antidilution protection".

Below you will find examples of how certain corporate actions and other events
may lead to adjustments to the stock redemption amount. In each case where the
stock redemption amount

S- 16
<PAGE>   17
SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

changes, the strike price (initial price) will generally also change. Typically,
the strike price will be adjusted as follows:

The calculation agent will adjust the strike price by multiplying the prior
strike price and a fraction whose numerator is the prior stock redemption amount
and whose denominator is the new stock redemption amount.

<TABLE>
<S>                 <C>                   <C>
New Strike Price =  Prior Strike Price X  Prior Stock Redemption Amount

                                           New Stock Redemption Amount
</TABLE>

HOW ADJUSTMENTS WILL BE MADE
If one of the events described below occurs and the calculation agent determines
that the event has a diluting or concentrative effect on the theoretical value
of the common stock of Cisco Systems, Inc., the calculation agent will calculate
a corresponding adjustment to the strike price or the stock redemption amount or
both as the calculation agent determines appropriate to account for that
diluting or concentrative effect. The calculation agent will also determine the
effective date of that adjustment, and the replacement of the underlying shares,
if applicable, in the event of consolidation or merger. Upon making any such
adjustment, the calculation agent will give notice as soon as practicable to the
trustee, stating the adjustment to the strike price or redemption amount or
both.

If more than one event requiring adjustment occurs, the calculation agent will
make such an adjustment for each event in the order in which the events occur,
and on a cumulative basis. Thus, having adjusted the strike price or the stock
redemption amount or both for the first event, the calculation agent will adjust
the strike price or the stock redemption amount or both for the second event,
applying the required adjustment to the strike price and stock redemption amount
as already adjusted for the first event, and so on for each event.

For any dilution event described below, other than a consolidation or merger,
the calculation agent will not have to adjust the strike price or the stock
redemption amount unless the adjustment would result in a change to the strike
price or the stock redemption amount of at least 0.1% in the strike price or
stock redemption amount that would apply without the adjustment. The strike
price or the stock redemption amount resulting from any adjustment will be
rounded up or down, as appropriate, to, in the case of the strike price, the
nearest cent, and, in the case of the stock redemption amount, the nearest
thousandth, with one-half cent and five hundred-thousandths, respectively, being
rounded upward.

If an event requiring antidilution adjustment occurs, the calculation agent will
make the adjustments with a view to offsetting, to the extent practical, any
change in your economic position relative to the GOALs, that results solely from
that event. The calculation agent may, in its sole discretion, modify the
antidilution adjustments as necessary to ensure an equitable result.

The calculation agent will make all determinations with respect to antidilution
adjustments, including any determination as to whether an event requiring
adjustment has occurred, as to the nature of the adjustment required and how it
will be made or as to the value of any property distributed in a reorganization
event, and will do so in its sole discretion. In the absence of manifest error,
those determinations will be conclusive for all purposes and will be binding on
you and us, without any liability on the part of the calculation agent. The
calculation agent will provide information about the adjustments it makes upon
your written request.

The following events are those that may require an antidilution adjustment

- a subdivision, consolidation or reclassification of index stock or a free
  distribution or dividend of any shares of index stock to existing holders of
  shares of the index stock by way of bonus, capitalization or similar issue

                                                                           S- 17
<PAGE>   18
SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

- a distribution or dividend to existing holders of shares of index stock of

     - shares of the index stock or

     - other share capital or securities granting the right to payment of
       dividends and/or the proceeds of liquidation of Cisco Systems, Inc.
       equally or proportionately with such payments to holders of shares of
       index stock or

     - any other type of securities, rights or warrants in any case for payment
       (in cash or otherwise) at less than the prevailing market price as
       determined by the calculation agent

- the declaration by Cisco Systems, Inc. of an extraordinary or special dividend
  or other distribution whether in cash or shares of index stock or other assets

- a repurchase by Cisco Systems, Inc. of its common stock whether out of profits
  or capital and whether the consideration for such repurchase is cash,
  securities or otherwise

- any other similar event that may have a diluting or concentrative effect on
  the theoretical value of the index stock

- a consolidation of Cisco Systems, Inc. with another company or merger of Cisco
  Systems, Inc. with another company.

STOCK SPLITS
A stock split is an increase in the number of a corporation's outstanding shares
of stock without any change in its stockholders' equity. Each outstanding share
will be worth less as a result of a stock split.

If Cisco Systems, Inc. is subject to a stock split, then the calculation agent
will adjust the stock redemption amount to equal the sum of the prior stock
redemption amount--i.e., the stock redemption amount before that
adjustment--plus the product of (1) the number of new shares issued in the stock
split with respect to one share of Cisco Systems, Inc. times (2) the prior stock
redemption amount.

REVERSE STOCK SPLITS
A reverse stock split is a decrease in the number of a corporation's outstanding
shares of stock without any change in its stockholders' equity. Each outstanding
share will be worth more as a result of a reverse stock split.

If Cisco Systems, Inc. is subject to a reverse stock split, then the calculation
agent will adjust the stock redemption amount to equal the product of the prior
stock redemption amount and the quotient of (1) the number of outstanding shares
of Cisco Systems, Inc. outstanding immediately after the reverse stock split
becomes effective divided by (2) the number of shares of Cisco Systems, Inc.
outstanding immediately before the reverse stock split becomes effective.

STOCK DIVIDENDS
In a stock dividend, a corporation issues additional shares of its stock to all
holders of its outstanding stock in proportion to the shares they own. Each
outstanding share will be worth less as a result of a stock dividend.

If Cisco Systems, Inc. is subject to a stock dividend payable in Cisco Systems,
Inc. common stock, then the calculation agent will adjust the stock redemption
amount to equal the sum of the prior stock redemption amount plus the product of
(1) the number of shares issued in the stock dividend with respect to one share
of Cisco Systems, Inc. common stock times (2) the prior stock redemption amount.

S- 18
<PAGE>   19
SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

OTHER DIVIDENDS AND DISTRIBUTIONS
The stock redemption amount will not be adjusted to reflect dividends or other
distributions paid with respect to Cisco Systems, Inc. common stock, other than

- stock dividends described above

- issuances of transferable rights and warrants as described in "--Transferable
  Rights and Warrants" below

- distributions that are spin-off events described in "--Reorganization Events"
  below, and

- extraordinary dividends described below.

A dividend or other distribution with respect to Cisco Systems, Inc. common
stock will be deemed to be an extraordinary dividend if its per share value
exceeds that of the immediately preceding non-extraordinary dividend, if any,
for Cisco Systems, Inc. common stock by an amount equal to at least 10% of the
closing price of Cisco Systems, Inc. common stock on the business day before the
ex-dividend date. The ex-dividend date for any dividend or other distribution is
the first day on which Cisco Systems, Inc. common stock trades without the right
to receive that dividend or distribution.

If an extraordinary dividend occurs, the calculation agent will adjust the stock
redemption amount to equal the product of (1) the prior stock redemption amount
times (2) a fraction, the numerator of which is the closing price of Cisco
Systems, Inc. common stock on the business day before the ex-dividend date and
the denominator of which is the amount by which that closing price exceeds the
extraordinary dividend amount.

The extraordinary dividend amount with respect to an extraordinary dividend for
Cisco Systems, Inc. common stock equals

- for an extraordinary dividend that is paid in lieu of a regular quarterly
  dividend, the amount of the extraordinary dividend per share of Cisco Systems,
  Inc. common stock minus the amount per share of the immediately preceding
  dividend, if any, that was not an extraordinary dividend for Cisco Systems,
  Inc. common stock, or

- for an extraordinary dividend that is not paid in lieu of a regular quarterly
  dividend, the amount per share of the extraordinary dividend.

To the extent an extraordinary dividend is not paid in cash, the value of the
non-cash component will be determined by the calculation agent. A distribution
on Cisco Systems, Inc. common stock that is a dividend payable in Cisco Systems,
Inc. common stock, an issuance of rights or warrants or a spin-off event and
also an extraordinary dividend will result in an adjustment to the stock
redemption amount only as described in "--Stock Dividends" above,
"--Transferable Rights and Warrants" below or "--Reorganization Events" below,
as the case may be, and not as described here.

TRANSFERABLE RIGHTS AND WARRANTS
If Cisco Systems, Inc. issues transferable rights or warrants to all holders of
Cisco Systems, Inc. common stock to subscribe for or purchase Cisco Systems,
Inc. common stock at an exercise price per share that is less than the closing
price of Cisco Systems, Inc. common stock on the business day before the
ex-dividend date for the issuance, then the stock redemption amount will be
adjusted by multiplying the prior stock redemption amount by the following
fraction

- the numerator will be the number of shares of Cisco Systems, Inc. common stock
  outstanding at the close of business on the day before that ex-dividend date
  plus the number of additional shares of Cisco Systems, Inc. common stock
  offered for subscription or purchase under those transferable rights or
  warrants, and

                                                                           S- 19
<PAGE>   20
SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

- the denominator will be the number of shares of Cisco Systems, Inc. common
  stock outstanding at the close of business on the day before that ex-dividend
  date plus the product of (1) the total number of additional shares of Cisco
  Systems, Inc. common stock offered for subscription or purchase under the
  transferable rights or warrants times (2) the exercise price of those
  transferable rights or warrants divided by the closing price on the business
  day before that ex-dividend date.

REORGANIZATION EVENTS
Each of the following is a reorganization event

- Cisco Systems, Inc. common stock is reclassified or changed

- Cisco Systems, Inc. has been subject to a merger, consolidation or other
  combination and either is not the surviving entity or is the surviving entity
  but all outstanding Cisco Systems, Inc. common stock is exchanged for or
  converted into other property

- a statutory share exchange involving outstanding Cisco Systems, Inc. common
  stock and the securities of another entity occurs, other than as part of an
  event described above

- Cisco Systems, Inc. sells or otherwise transfers its property and assets as an
  entirety or substantially as an entirety to another entity

- Cisco Systems, Inc. effects a spin-off--that is, issues to all holders of
  Cisco Systems, Inc. common stock equity securities of another issuer, other
  than as part of an event described above

- Cisco Systems, Inc. is liquidated, dissolved or wound up or is subject to a
  proceeding under any applicable bankruptcy, insolvency or other similar law,
  or another entity completes a tender or exchange offer for all the outstanding
  Cisco Systems, Inc. common stock.

ADJUSTMENTS FOR REORGANIZATION EVENTS
If a reorganization event occurs, then the calculation agent will adjust the
stock redemption amount by adjusting the amount and type of property deliverable
on the stated maturity date in exchange for each $1,000 of outstanding principal
amount of the GOALs, which we refer to as the "reference amount". Initially, the
reference amount will be the amount of Cisco Systems, Inc. common stock
specified above. However, if the stock redemption amount is adjusted because of
a dilution event, then the reference amount will be adjusted in a corresponding
manner. For example, if a stock redemption amount adjustment is required because
of a stock split, reverse stock split, stock dividend, extraordinary dividend or
issuance of rights or warrants, then the reference amount might be adjusted to
be a proportion or multiple of the amount of Cisco Systems, Inc. common stock
specified herein, depending on the event requiring adjustment.

Similarly, if adjustment is required because of a reorganization event in which
cash and securities are distributed, for example, the reference amount will be
adjusted to be the amount of cash and the securities distributed in the event in
respect of the amount of Cisco Systems, Inc. common stock specified herein, if
there has been no prior adjustment of the stock redemption amount. If there has
been a prior adjustment, the reference amount will be adjusted to be the amount
of cash and the securities distributed in the event in respect of the specified
amount of Cisco Systems, Inc. common stock or whatever else the reference amount
might be when the distribution occurs.

If a reorganization event occurs, the reference amount will be adjusted so as to
consist of the amount and type of property--whether it be cash, securities or
other property--distributed in the event in respect of the prior reference
amount. If more than one type of property is distributed, the reference amount
will be adjusted so as to consist of each type of property distributed in
respect of the prior reference amount, in a proportionate amount so that the
value of each type of property comprising the new reference amount as a
percentage of the total value of the new reference amount equals the value

S- 20
<PAGE>   21
SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

of that type of property as a percentage of the total value of all property
distributed in the reorganization event in respect of the prior reference
amount.

For the purposes of making an adjustment required by a reorganization event, the
calculation agent will determine the value of each type of property distributed
in the distribution, in its sole discretion. For any distribution property
consisting of a security, the calculation agent will use the closing price for
the security on the exchange date. The calculation agent may value other types
of property in any manner it determines, in its sole discretion, to be
appropriate. If a holder of Cisco Systems, Inc. common stock may elect to
receive different types or combinations of types of distribution property in the
reorganization event, the distribution property will consist of the types and
amounts of each type distributed to a holder that makes no election, as
determined by the calculation agent.

If a reorganization event occurs and the calculation agent adjusts the reference
amount to consist of the property distributed in the event as described above,
the calculation agent will make further anti-dilution adjustments for later
events that affect the distribution property, or any component of the
distribution property, comprising the new reference amount. The calculation
agent will do so to the same extent that it would make adjustments if the Cisco
Systems, Inc. common stock were outstanding and were affected by the same kinds
of events. If a subsequent reorganization event affects only a particular
component of the reference amount, the required adjustment will be made with
respect to that component, as if it alone were the reference amount.

For example, if Cisco Systems, Inc. merges into another company and each share
of Cisco Systems, Inc. common stock is converted into the right to receive two
common shares of the surviving company and a specified amount of cash, the
reference amount will be adjusted to consist of two common shares and the
specified amount of cash. The calculation agent will adjust the common share
component of the new reference amount to reflect any later stock split or other
event, including any later reorganization event, that affects the common shares
of the surviving company, to the extent described in this section entitled
"--Antidilution Adjustments" as if the common shares were Cisco Systems, Inc.
common stock. In that event, the cash component will not be adjusted but will
continue to be a component of the reference amount. Consequently, holders of
GOALs who receive shares of Cisco Systems, Inc. at maturity will be entitled to
receive, for each $1,000 of the outstanding principal amount of the GOALs being
exchanged, all components of the reference amount in effect on the exchange
date, with each component having been adjusted on a sequential and cumulative
basis for all relevant events requiring adjustment on or before the exchange
date.

In this prospectus supplement, references to the calculation agent adjusting the
stock redemption amount in respect of a dilution event means that the
calculation agent will adjust the reference amount in the manner described in
this subsection if the dilution event is a reorganization event.

DISTRIBUTION PROPERTY
The term "distribution property" used in this prospectus supplement means the
cash, securities and other property or assets distributed in a reorganization
event in respect of an amount outstanding of Cisco Systems, Inc. common stock
equal to the amount specified above as the redemption amount or in respect of
whatever the reference amount may then be if any antidilution adjustment has
been made in respect of a prior event. In the case of a spin-off, the
distribution property also includes the specified amount of Cisco Systems, Inc.
common stock--or other applicable reference amount--in respect of which the
distribution is made.

If a reorganization event occurs, the distribution property distributed in the
event will be substituted for Cisco Systems, Inc. common stock as described
above. Consequently, in this prospectus supplement, references to Cisco Systems,
Inc. common stock mean any distribution property that is

                                                                           S- 21
<PAGE>   22

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

distributed in a reorganization event and comprises the adjusted reference
amount. Similarly, references to Cisco Systems, Inc. mean any successor entity
in a reorganization event.

DEFAULT AMOUNT ON ACCELERATION

If an event of default occurs and the maturity of the GOALs is accelerated, we
will pay the default amount in respect of the principal of the GOALs at
maturity. We describe the default amount below under "--Special Calculation
Provisions."

For the purpose of determining whether the holders of our Series A medium-term
notes, of which the GOALs are a part, are entitled to take any action under the
indenture, we will treat the outstanding principal amount of the GOALs as the
outstanding principal amount of that note. Although the terms of the GOALs may
differ from those of the other Series A medium-term notes, holders of specified
percentages in principal amount of all Series A medium-term notes, together in
some cases with other series of our debt securities, will be able to take action
affecting all the Series A medium-term notes, including the GOALs. This action
may involve changing some of the terms that apply to the Series A medium-term
notes, accelerating the maturity of the Series A medium-term notes after a
default or waiving some of our obligations under the indenture. We discuss these
matters in the attached prospectus under "Description of Debt Securities We May
Offer--Default, Remedies and Waiver of Default" and "--Modification and Waiver
of Covenants."

MANNER OF PAYMENT AND DELIVERY

Any payment or delivery on the GOALs at maturity will be made to accounts
designated by you and approved by us, or at the office of the trustee in New
York City, but only when the GOALs are surrendered to the trustee at that
office. We also may make any payment or delivery in accordance with the
applicable procedures of the depositary. We may make any delivery of index stock
or distribution property ourselves or cause our agent to do so on our behalf.

MODIFIED BUSINESS DAY

As described in the attached prospectus, any payment on the GOALs that would
otherwise be due on a day that is not a business day may instead be paid on the
next day that is a business day, with the same effect as if paid on the original
due date, except as described under "Maturity Date" and "Determination Date"
above. The same will apply to any delivery of the index stock that would
otherwise be due on a day that is not a business day. For the GOALs, however,
the term business day has a different meaning than it does for other Series A
medium-term notes. We discuss this term under "--Special Calculation Provisions"
below.

ROLE OF CALCULATION AGENT

The calculation agent will make all determinations regarding the antidilution
adjustments, market disruption events, the closing price or other value of the
index stock and the default amount. Absent manifest error, all determinations of
the calculation agent will be final and binding on you and us, without any
liability on the part of the calculation agent.

Please note that the firm named as the calculation agent in this prospectus
supplement is the firm serving in that role as of the original issue date of the
GOALs. We may change the calculation agent after the original issue date without
notice.

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

SPECIAL CALCULATION PROVISIONS

BUSINESS DAY

When we refer to a business day with respect to the GOALs, we mean a day that is
a business day of the kind described in the attached prospectus but that is not
a day on which the principal securities market for the index stock is authorized
by law or executive order to close.

CLOSING PRICE
The closing price for any security on any day will equal the closing sale price
or last reported sale price, regular way, for the security, on a per-share or
other unit basis:

-  on the principal national securities exchange on which that security is
   listed for trading on that day, or

-  if that security is not listed on any national securities exchange, on the
   Nasdaq National Market System on that day, or

-  if that security is not quoted on the Nasdaq National Market System on that
   day, on any other U.S. national market system that is the primary market for
   the trading of that security.

If that security is not listed or traded as described above, then the closing
price for that security on any day will be the average, as determined by the
calculation agent, of the bid prices for the security obtained from as many
dealers in that security selected by the calculation agent as will make those
bid prices available to the calculation agent. The number of dealers need not
exceed three and may include the calculation agent or any of its or our
affiliates.

DEFAULT AMOUNT

The default amount for the GOALs on any day will be an amount, in the specified
currency for the principal of the GOALs, equal to the cost of having a qualified
financial institution, of the kind and selected as described below, expressly
assume all our payment and other obligations with respect to the GOALs as of
that day and as if no default or acceleration had occurred, or to undertake
other obligations providing substantially equivalent economic value to you with
respect to the GOALs. That cost will equal:

- the lowest amount that a qualified financial institution would charge to
  effect this assumption or undertaking, plus

- the reasonable expenses, including reasonable attorneys' fees, incurred by the
  holders of the GOALs in preparing any documentation necessary for this
  assumption or undertaking.

During the default quotation period for the GOALs, which we describe below, the
holders of the GOALs and/or we may request a qualified financial institution to
provide a quotation of the amount it would charge to effect this assumption or
undertaking. If either party obtains a quotation, it must notify the other party
in writing of the quotation. The amount referred to in the first bullet point
above will equal the lowest--or, if there is only one, the only--quotation
obtained, and as to which notice is so given, during the default quotation
period. With respect to any quotation, however, the party not obtaining the
quotation may object, on reasonable and significant grounds, to the assumption
or undertaking by the qualified financial institution providing the quotation
and notify the other party in writing of those grounds within two business days
after the last day of the default quotation period, in which case that quotation
will be disregarded in determining the default amount.

                                                                           S- 23

SPECIFIC TERMS OF THE GOALS
--------------------------------------------------------------------------------

DEFAULT QUOTATION PERIOD

The default quotation period is the period beginning on the day the default
amount first becomes due and ending on the third business day after that day,
unless:

- no quotation of the kind referred to above is obtained or

- every quotation of that kind obtained is objected to within five business days
  after the due date as described above.

If either of these two events occurs, the default quotation period will continue
until the third business day after the first business day on which prompt notice
of a quotation is given as described above. If that quotation is objected to as
described above within five business days after that first business day,
however, the default quotation period will continue as described in the prior
sentence and this sentence.

In any event, if the default quotation period and the subsequent two business
day objection period have not ended before the determination date, then the
default amount will equal the principal amount of the GOALs.

QUALIFIED FINANCIAL INSTITUTIONS.

For the purpose of determining the default amount at any time, a qualified
financial institution must be a financial institution organized under the laws
of any jurisdiction in the United States of America, Europe or Japan, which at
that time has outstanding debt obligations with a stated maturity of one year or
less from the date of issue and rated either:

- A-1 or higher by Standard & Poors' Ratings Group or any successor, or any
  other comparable rating then used by that rating agency, or

- P-1 or higher by Moody's Investors Service, Inc. or any successor, or any
  other comparable rating then used by that rating agency.

BOOKING BRANCH

The GOALs will be booked through UBS AG, Jersey branch.

Use of Proceeds and Hedging

We will use the net proceeds we receive from the sale of the GOALs for the
purposes we describe in the attached prospectus under "Use of Proceeds." We or
our affiliates may also use those proceeds in transactions intended to hedge our
obligations under the GOALs as described below.

In anticipation of the sale of the GOALs, we or our affiliates expect to enter
into hedging transactions involving purchases of the index stock and listed or
over-the-counter options on the index stock prior to and on the trade date. From
time to time, we or our affiliates may enter into additional hedging
transactions or unwind those we have entered into. In this regard, we or our
affiliates may:

- acquire or dispose of the index stock or other securities of Cisco Systems,
  Inc.,

- take or dispose of positions in listed or over-the-counter options or other
  instruments based on the index stock and/or

- take or dispose of positions in listed or over-the-counter options or other
  instruments based on indices designed to track the performance of the Nasdaq
  National Market or other components of the U.S. equity market.

We or our affiliates may acquire a long or short position in securities similar
to the GOALs from time to time and may, in our or their sole discretion, hold or
resell those securities.

We or our affiliates may close out our or their hedge on or before the
determination date. That step may involve sales or purchases of the index stock,
listed or over-the-counter options on the index stock or listed or
over-the-counter options or other instruments based on indices designed to track
the performance of the Nasdaq National Market or other components of the U.S.
equity market.

The hedging activity discussed above may adversely affect the market value of
the GOALs from time to time. See "Risk Factors" above for a discussion of these
adverse effects.

                                                                           S- 25

Supplemental Tax Considerations

The following is a general description of certain United States and Swiss tax
considerations relating to the GOALs. It does not purport to be a complete
analysis of all tax considerations relating to the GOALs. Prospective purchasers
of GOALs should consult their tax advisers as to the consequences under the tax
laws of the country of which they are resident for tax purposes and the tax laws
of Switzerland and the United States of acquiring, holding and disposing of
GOALs and receiving payments of interest, principal and/or other amounts under
the GOALs. This summary is based upon the law as in effect on the date of this
prospectus supplement and is subject to any change in law that may take effect
after such date.

SUPPLEMENTAL U.S. TAX CONSIDERATIONS

The discussion below supplements the discussion under "U.S. Tax Considerations"
in the attached prospectus and is subject to the limitations and exceptions set
forth therein. Except as otherwise noted under "Non-United States Holders"
below, this discussion is only applicable to you if you are a United States
holder (as defined in the accompanying prospectus).

In the opinion of our counsel, Sullivan & Cromwell, it would be reasonable to
treat your GOAL as either (i) an investment unit consisting of a non-contingent
debt instrument issued by us to you (the "Debt Portion") and a put option on the
index stock written by you and purchased by us (the "Put Option") or (ii) a
single contingent debt instrument subject to the special tax rules governing
contingent debt instruments. The discussion below discusses the United States
federal income tax consequences that would be applicable to you under either
characterization. The terms of your GOAL, however, require you and us (in the
absence of an administrative determination or judicial ruling to the contrary)
to treat your GOAL for all tax purposes as an investment unit consisting of the
Debt Portion and Put Option. In purchasing your GOAL, you agree to these terms.

NO STATUTORY, JUDICIAL OR ADMINISTRATIVE AUTHORITY DIRECTLY DISCUSSES HOW YOUR
GOAL SHOULD BE TREATED FOR UNITED STATES FEDERAL INCOME TAX PURPOSES. AS A
RESULT, THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF YOUR INVESTMENT IN
A GOAL ARE UNCERTAIN. ACCORDINGLY, WE URGE YOU TO CONSULT YOUR TAX ADVISOR AS TO
THE TAX CONSEQUENCES OF HAVING AGREED TO THE REQUIRED TAX TREATMENT OF YOUR GOAL
DESCRIBED ABOVE AND AS TO THE APPLICATION OF STATE, LOCAL OR OTHER TAX LAWS TO
YOUR INVESTMENT IN YOUR GOAL.

Treatment as an Investment Unit.  If your GOAL is properly treated as an
investment unit consisting of a Debt Portion and Put Option, it is likely that
the Debt Portion of your GOAL would be treated as having been issued for the
principal amount of the GOAL and that interest payments on the GOAL would be
treated in part as payments of interest and in part as payments for the Put
Option. Amounts treated as interest would be includible in income by you in
accordance with your regular method of accounting for interest for United States
federal income tax purposes. Amounts treated as payment for the Put Option would
be deferred and would either be included in income by you upon the maturity,
early redemption or sale of your GOAL or would reduce the basis of any index
stock you receive upon the maturity or early redemption of your GOAL. The terms
of your GOAL require you and us to treat the Debt Portion as paying annual
interest of 5.2% and the Put Option as paying annual payments of 14.3%.

A cash payment of the principal amount of your GOAL upon the maturity of your
GOAL would likely be treated as (i) payment in full of the principal amount of
the Debt Portion, which would likely not result in the recognition of gain or
loss if you are an initial purchaser of your GOAL and (ii) the lapse of the Put
Option which would likely result in your recognition of short-term capital gain
in an

S- 26
<PAGE>   27
SUPPLEMENTAL TAX CONSIDERATIONS
--------------------------------------------------------------------------------

amount equal to the amount paid to you for the Put Option and deferred as
described in the preceding paragraph.

A payment of index stock upon the maturity of your GOAL would likely be treated
as (i) payment in full of the principal amount of the Debt Portion, which would
likely not result in the recognition of gain or loss if you are an initial
purchaser of your GOAL and (ii) the exercise by us of the Put Option and your
purchase of the index stock for an amount equal to the principal amount of your
GOAL. Your United States federal income tax basis in the index stock you receive
would equal the principal amount of your GOAL less the amount of payments you
received for the Put Option and deferred as described in the second preceding
paragraph. Your holding period in the index stock you receive would begin on the
day after you beneficially receive such index stock. If you receive cash in lieu
of a fractional share of index stock, you would recognize a short-term capital
gain or loss in an amount equal to the difference between the amount of cash you
receive and your tax basis (determined in the manner described above) in the
fractional share.

Upon an early redemption or sale of your GOAL for cash or index stock, you would
be required to apportion the value of the amount you receive between the Debt
Portion and Put Option on the basis of the values thereof on the date of the
redemption or sale. You would recognize gain or loss with respect to the Debt
Portion in an amount equal to the difference between (i) the amount apportioned
to the Debt Portion and (ii) your adjusted United States federal income tax
basis in the Debt Portion (which would generally be equal to the principal
amount of your GOAL if you are an initial purchaser of your GOAL). Except to the
extent attributable to accrued but unpaid interest with respect to the Debt
Portion, such gain or loss would be long-term capital gain or loss if your
holding period in your GOAL is greater than one year. The amount of cash or
index stock that you receive that is apportioned to the Put Option (together
with any amount of premium received in respect thereof and deferred as described
in the preceding paragraph) would be treated as short-term capital gain. If the
value of the Debt Portion on the date of the sale or early redemption of your
GOAL is in excess of the amount you receive upon such sale or early redemption,
you would likely be treated as having made a payment (to us in the case of an
early redemption or to the purchaser in the case of a sale) equal to the amount
of such excess in order to extinguish your rights and obligations under the Put
Option. In such a case, you would likely recognize short-term capital gain or
loss in an amount equal to the difference between the premium you previously
received in respect of the Put Option and the amount of the deemed payment made
by you to extinguish the Put Option.

If you are a secondary purchaser of your GOAL, you would be required to allocate
your purchase price for your GOAL between the Debt Portion and Put Option based
on the respective fair market values of each on the date of purchase. If,
however, the portion of your purchase price allocated to the Debt Portion in
accordance with the preceding sentence is in excess of your purchase price for
your GOAL, you would likely be treated for tax purposes as having paid nothing
for the Put Option (i.e., your purchase price for the Put Option would be zero)
and as having received a payment for obligating yourself under the Put Option
(which will be deferred as described in the fourth preceding paragraph) in an
amount equal to such excess. If the portion of your purchase price allocated to
the Debt Portion is at a discount from, or is in excess of, the principal amount
of your GOAL, you may be subject to the market discount or amortizable bond
premium rules described in the accompanying prospectus under "U.S. Tax
Considerations--Original Issue Discount--Market Discount" and "U.S. Tax
Considerations--Notes Purchased at a Premium" with respect to the Debt Portion.
The portion of your purchase price, if any, that is allocated to the Put Option
would likely be offset for tax purposes against amounts you subsequently receive
with respect to the Put Option (including amounts received upon a sale of the
GOAL that are attributable to the Put Option), thereby reducing the amount of
gain or increasing the amount of loss you would recognize with respect to the
Put Option or with respect to the sale of any index stock you receive upon the
exercise of the Put Option.

                                                                           S- 27

SUPPLEMENTAL TAX CONSIDERATIONS
--------------------------------------------------------------------------------

     Example of Tax Treatment as an Investment Unit.  The following example is
     for illustrative purposes only. Assume that you purchased a GOAL on the
     initial issuance with an underlying stock issued by a hypothetical XYZ
     Company at par for $1,000 and will receive a 16% annual coupon. Assume
     further that the $160 annual coupon consists of an interest payment on the
     Debt Portion of 6%, or $60, and a payment with respect to the Put Option of
     10%, or $100. Under the treatment agreed to, you would include the interest
     portion of $60 in ordinary income in the year it is received or accrued,
     depending on your accounting method for tax purposes. Initially, the
     portion of the coupon attributable to the Put Option ($100) would not be
     subject to tax.

     For an 18 month GOAL that is not sold prior to maturity, the coupon
     payments would total $240, $90 of which would be taxed as ordinary interest
     income in the year it is received or accrued and $150 of which would not be
     subject to tax until maturity. If the share price of XYZ Company is equal
     to or higher than the initial stock price of $100 at maturity, you would
     receive $1,000 cash and recognize a short-term capital gain of $150 (that
     is, the amount of the payments previously received by you with respect to
     the Put Option). If the share price of XYZ Company at maturity is below the
     $100 initial stock price, you would receive 10 shares of XYZ Company stock
     for your GOALs (that is, $1,000 principal amount/$100 per share initial
     price = 10 shares). Your basis in the shares received would be $850, which
     is the initial purchase price of your GOAL ($1,000) less the payments
     previously made to you with respect to the Put Option ($150).

     The above example can be summarized as follows:

    Net cost basis..............................................                      $850

Alternative Characterization.  If your GOAL is properly treated as a single debt
instrument subject to the special U.S. Treasury Regulations governing contingent
debt instruments, the amount of interest

S- 28
<PAGE>   29
SUPPLEMENTAL TAX CONSIDERATIONS
--------------------------------------------------------------------------------

you would be required to take into account for each accrual period would be
determined by constructing a projected payment schedule for your GOAL and
applying rules similar to those for accruing original issue discount on a
hypothetical non-contingent debt instrument with that projected payment
schedule. This method is applied by first determining the yield at which we
would issue a non-contingent fixed rate debt instrument with other terms and
conditions similar to the GOAL and then determining as of the issue date a
payment schedule (including all fixed payments of interest actually provided for
and a hypothetical payment at maturity) that would produce the comparable yield.
These rules would generally have the effect of (i) treating each payment of
stated interest on your GOAL in part as taxable interest income (to the extent
of the comparable yield) and thereafter as a tax-free return of capital and (ii)
requiring you to use an accrual (rather than the cash receipts and
disbursements) method of accounting with respect to interest on your GOAL.

If your GOAL is treated as a contingent debt instrument, you would recognize
gain or loss upon the sale, early redemption or maturity of your GOAL in an
amount equal to the difference, if any, between the cash or the fair market
value of any index stock received at such time and your adjusted United States
federal income tax basis in your GOAL. In general, your adjusted United States
federal income tax basis in your GOAL would equal the amount you paid for your
GOAL, increased by the amount of interest you previously accrued with respect to
your GOAL (in accordance with the comparable yield and the projected payment
schedule) and decreased by the amount of interest payments you received with
respect to your GOAL. Any gain recognized by you upon the sale, early redemption
or maturity of your GOAL would be ordinary interest income and any loss
recognized by you at such time would be ordinary loss to the extent of interest
you included as income in the current or previous taxable years in respect of
your GOAL, and thereafter, capital loss. Your holding period in any index stock
received upon the maturity of your GOAL would begin on the day after your
receipt of the index stock.

If your GOAL is treated as a contingent debt instrument and you purchase your
GOAL in the secondary market at a price that is at a discount from, or in excess
of, the adjusted issue price of your GOAL, such excess or discount would not be
subject to the generally applicable market discount and amortizable bond premium
rules described in the accompanying prospectus but rather would be subject to
special rules set forth in Treasury Regulations governing contingent debt
instruments. Accordingly, if you purchase your GOAL in the secondary market at a
price other than the adjusted issue price of your GOAL, you should consult your
tax advisor as to the possible application of such rules to you.

Wash Sale Rules.  If you purchase your GOAL at original issue and you sell
shares of the index stock prior or subsequent to such purchase, your purchase of
a GOAL will not cause you to be subject to any restriction or limitation with
respect to the recognition of loss, if any, for federal income tax purposes upon
your sale of the index stock. If you are a secondary purchaser of a GOAL or if
you have shorted shares of the index stock, you should consult your tax advisor
regarding the possible application of the wash sale rules to your sale of shares
of the index stock prior or subsequent to your purchase of a GOAL.

Non-United States Holders.  If you are not a United States holder, you will not
be subject to United States withholding tax with respect to payments on your
GOAL but you will be subject to generally applicable information reporting and
backup withholding requirements with respect to payments on your GOAL unless you
comply with certain certification and identification requirements as to your
foreign status.

SUPPLEMENTAL TAX CONSIDERATIONS UNDER THE LAWS OF SWITZERLAND

TAX ON PRINCIPAL AND INTEREST
Under present Swiss law, payment of interest on and repayment of principal of
the GOALs by us are not subject to Swiss withholding tax (Swiss Anticipatory
Tax), and payments to holders of the GOALs

                                                                           S- 29

who are non-residents of Switzerland and who during the taxable year have not
engaged in trade or business through a permanent establishment within
Switzerland will not be subject to any Swiss Federal, Cantonal or Municipal
income tax.

GAINS ON SALE OR REDEMPTION
Under present Swiss Law, a holder of GOALs who is a non-resident of Switzerland
and who during the taxable year has not engaged in trade or business through a
permanent establishment within Switzerland will not be subject to any Swiss
Federal, Cantonal or Municipal income or other tax on gains realized during the
year on the sale or redemption of a GOAL.

STAMP, ISSUE AND OTHER TAXES
There is no tax liability in Switzerland in connection with the issue and
redemption of the GOALs. However, GOALs sold through a bank or other dealer
resident in Switzerland or Liechtenstein are subject to Turnover Tax.

RESIDENTS OF SWITZERLAND
For residents of Switzerland, for tax purposes, that portion of the annual
interest payment representing interest shall be treated as income and that
portion of the annual interest payment representing an option premium shall be
treated as a capital gain.

ERISA Considerations

We, UBS Warburg LLC, PaineWebber Incorporated and other of our affiliates may
each be considered a "party in interest" within the meaning of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") or a "disqualified
person" (within the meaning of Section 4975 of the Internal Revenue Code of
1986, as amended (the "Code")) with respect to an employee benefits plan that is
subject to ERISA and/or an individual retirement account that is subject to the
Code ("Plan"). The purchase of GOALs by a Plan with respect to which UBS Warburg
LLC, PaineWebber Incorporated or any of our affiliates acts as a fiduciary as
defined in Section 3(21) of ERISA and/or Section 4975 of the Code ("Fiduciary")
would constitute a prohibited transaction under ERISA or the Code unless
acquired pursuant to and in accordance with an applicable exemption. The
purchase of GOALs by a Plan with respect to which UBS Warburg LLC, PaineWebber
Incorporated or any of our affiliates does not act as a Fiduciary but for which
any of the above entities does provide services could also be prohibited, but
one or more exemptions may be applicable. Any person proposing to acquire any
GOAL on behalf of a Plan should consult with counsel regarding the applicability
of the prohibited transaction rules and the applicable exemptions thereto.

                                                                           S- 31

Use of proceeds...............   We intend to use the net proceeds from the
                                 sales of the notes to provide additional funds

                                 corporate purposes.

                                 our Jersey branch, our London branch, or such
                                 other branch as specified in the applicable

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth UBS AG's ratio of earnings to fixed charges, for
the periods indicated.

------------
(1)  The ratio is provided using both IAS and US GAAP values, as the ratio is
     materially different between the two accounting standards. No US GAAP
     information is provided for 31 December 1997 and 30 June 1999 as a US GAAP
     reconciliation was not required for those periods.

(2)  The deficiency in the coverage of fixed charges by earnings before fixed
     charges on an IAS basis at 31 December 1997 of CHF 851 million is due to
     restructuring charges of CHF 7,000 million under IAS charged in that
     period. Without that charge, the ratio would have been 1.36.

(3)  The deficiency in the coverage of fixed charges by earnings before fixed
     charges at 31 December 1998 of CHF 5,319 million is due to restructuring
     charges of CHF 3,982 million under US GAAP, as well as 1,706 million of
     pre-tax losses from significant financial events charged for that period.
     See "Management's Discussion and Analysis of Financial Condition and
     Results of Operation -- Introduction." Without those charges the ratio
     would have been 1.01.

Use of Proceeds

UBS AG intends to use the proceeds from the sale of the notes to provide
additional funds for our operations and for general corporate purposes outside
of Switzerland. We will receive the net proceeds from sales of the notes made in
connection with their original issuance and in connection with any market-making
resales UBS AG undertakes. We have not received, and do not expect to receive,
any proceeds from resales of the notes by UBS Warburg LLC, PaineWebber
Incorporated or any of our other affiliates in market-making transactions. We
expect our affiliates to retain the proceeds of their market-making resales and
not to pay the proceeds to us.

Cautionary Note Regarding Forward-looking Information

This prospectus contains forward-looking information. The Private Securities
Litigation Reform Act of 1995 provides a "safe harbor" for forward-looking
information to encourage companies to provide prospective information about
themselves without fear of litigation so long as the information is identified
as forward looking and is accompanied by meaningful cautionary statements
identifying important factors that could cause actual results to differ
materially from those projected in the information. Forward-looking information
is indicated by the use of words such as "anticipates," "expects," "believes,"
"should," "could," "intends," "estimates" and "may," or other comparable
language. We identify the following important factors that could cause UBS's
actual results to differ materially from any results that might be projected by
UBS in forward-looking information. All of these factors are difficult to
predict, and many are beyond the control of UBS. Accordingly, although we
believe that the assumptions underlying the forward-looking information are
reasonable, there can be no assurance that those assumptions will approximate
actual experience.

The important factors include, among others, the following:

-  general economic conditions, including prevailing interest rates and
   performance of financial markets, which may affect UBS's ability to sell its
   products,

-  the market value of UBS's investments,

-  UBS's and PaineWebber's ability to achieve anticipated cost savings and
   efficiencies from their merger, to integrate their sales and distribution
   channels in a timely manner and to retain their key employees,

-  changes in federal tax laws, which could adversely affect the tax advantages
   of certain of UBS's products and subject it to increased taxation,

-  industry consolidation and competition,

-  changes affecting the banking industry generally and UBS's banking operations
   specifically, including asset quality,

-  increasing levels of competition in emerging markets and general competitive
   factors, locally, nationally, regionally and globally, and

-  changes in currency exchange rates, including the exchange rate for the Swiss
   franc into U.S. dollars.

You should also consider other risks and uncertainties discussed in documents
filed by UBS with the SEC, including UBS's most recent Annual Report on Form
20-F for the fiscal year ended December 31, 1999. We have no obligation to
update forward-looking information to reflect actual results.

UBS

DESCRIPTION OF BUSINESS

Mission

The UBS mission is to:

     -  provide clients with superior value-added investment services;

     -  provide above average rewards to shareholders;

     -  be an employer of choice; and

     -  be a good corporate citizen.

Overview

UBS is a global, integrated investment services firm and the leading bank in
Switzerland. UBS's business is managed through three main business groups and
UBS's Corporate Center. The business groups are:

     -  UBS Switzerland;

     -  UBS Warburg; and

     -  UBS Asset Management.

The philosophy of UBS's business model is that each of the business groups holds
primary responsibility for managing relationships with well-defined client
segments, while ensuring appropriate access to the products and services of the
entire Group. UBS's clients include international corporations, small- and
medium-sized businesses in Switzerland, governments and other public bodies,
financial institutions, market participants and individuals. Individuals include
high net worth individuals, affluent clients and retail customers. UBS provides
its clients with a broad range of products and services. These include:

     -  wealth management services;

     -  investment funds;

     -  corporate advisory (mergers and acquisitions) services;

     -  equity and debt underwriting;

     -  securities and financial market research;

     -  securities and derivatives sales and trading;

     -  structured risk management;

     -  retail, commercial and transaction banking in Switzerland;

     -  asset management; and

     -  private equity funds.

Each of the business groups is one of the leaders in its field. UBS has the

as measured by assets under management. UBS Warburg is among the leading
corporate and institutional investment banks, and it is differentiated by its
European roots. UBS is the leading retail and commercial bank in Switzerland.

UBS
--------------------------------------------------------------------------------

UBS's Corporate Center encompasses Group level functions that cannot be
delegated to the business groups.

All of UBS's business groups work together in an integrated investment services
firm. UBS believes this allows it to provide several types of services to its
clients, resulting in additional profits. Examples of inter-group synergies
include:

-  UBS Warburg provides research, securities brokerage and foreign exchange
   execution services to clients of UBS Switzerland.

-  UBS Switzerland and UBS Warburg banking clients also have the opportunity to
   invest in UBS Capital and UBS Asset Management funds.

-  UBS Asset Management researches and recommends the asset allocation
   strategies employed by UBS Warburg and UBS Switzerland, in particular with
   respect to investment funds.

-  Technology and premises infrastructure, operations and other support services
   are generally shared between all business groups in a given country,
   especially in Switzerland.

Set forth below is summary information relating to UBS.

(2) Assets under management is defined as third-party on- and off-balance sheet
    assets for which UBS has investment responsibility, as well as deposits and
    current accounts. This includes discretionary assets (deposited with UBS or
    externally), where UBS has a mandate to invest and manage the assets, as
    well as advisory assets. The major product categories of assets under
    management are mutual funds, securities (bonds and equities) and deposit and
    current accounts.

UBS's financial stability stems from the fact that it is one of the most well
capitalized banks in the world. UBS believes that this financial strength is a
key part of the value proposition offered to both clients and investors. The
long-term credit ratings assigned to UBS by rating agencies are set out below.

Strategy

UBS seeks to grow the profitability and enhance the efficiency of all of its
businesses, while continuously improving the provision of products and services
to its clients. UBS will build its franchise either through investments in
internal growth or, where appropriate, through selected acquisitions, such as
the merger with PaineWebber. UBS believes that its business model and its recent
history of embracing and managing change will enable flexible responses to the
rapid and unpredictable changes taking place in the financial services industry.
In order to maintain an edge in the highly competitive markets in which UBS
operates, UBS will continue to make ongoing investments in top quality staff and
technology.

In addition to the delivery of products and services through traditional
channels, UBS is strengthening its e-commerce initiatives. UBS's business groups
are well advanced in formulating and implementing their e-commerce strategies.

- UBS Switzerland will invest CHF 90-100 million annually over the next few
  years to extend its electronic banking and mobile phone banking initiatives.
  Since April 2000, a single unit has been responsible for handling all the
  business group's e-banking activities with its primary goal being to bring
  personalized service to private clients. A further goal is to expand
  relationships with active online clients, strengthening cross-selling in the
  process.

- UBS Warburg has launched its web-based business-to-business solution,
  Investment Banking On-Line or "IBOL". From the IBOL homepage, corporate and
  institutional clients can access services and content electronically and link
  to execution capabilities across all product areas.

Background

On 29 June 1998, Union Bank of Switzerland and Swiss Bank Corporation merged to
form UBS. Union Bank of Switzerland was created by the merger of two Swiss
regional banks in 1912; these two Swiss regional banks can trace their history
back to 1862 and 1863. Swiss Bank Corporation was incorporated in Basel in 1872
and its history can be traced back to the creation of "Bankverein" from six
private banking houses in 1854.

Prior to the 1998 merger, Union Bank of Switzerland developed primarily through
internal growth, although it made certain significant acquisitions such as
Phillips & Drew in 1985. Swiss Bank Corporation expanded mainly through
acquisitions. These included the acquisitions of:

- O'Connor & Associates, a group of affiliated firms specializing in the trading
  of options and other derivative instruments (1992);

- Brinson Partners, a leading institutional investment management firm in terms
  of assets under management (1995);

- the investment banking operating subsidiaries of S.G. Warburg Group p.l.c.
  (1995); and

- Dillon Read & Co., Inc., a United States-based investment bank (1997).

UBS
--------------------------------------------------------------------------------

The integration of Union Bank of Switzerland and Swiss Bank Corporation was
largely completed within one year, despite the additional challenges presented
by preparation for the Year 2000 and the introduction of the euro.

Merger with PaineWebber

On 3 November 2000, UBS acquired Paine Webber Group Inc. UBS purchased all
outstanding shares of PaineWebber stock for a combination of cash and stock
representing a total purchase price of $11.8 billion (based on the UBS share
price on 3 November 2000).

PaineWebber is one of the largest full-service securities and commodities firms
in the United States. Founded in 1879, PaineWebber employs approximately 23,175
people in 385 offices worldwide.

PaineWebber offers a wide variety of products and services, consisting of those
of a full service broker-dealer to primarily a domestic market, through its two
operating segments: Individual and Institutional. The Individual segment offers
brokerage services and products, asset management and other investment advisory
and portfolio management products and services, and execution and clearing
services for transactions originated by individual investors. The Institutional
segment principally includes capital markets products and services such as
securities dealer activities and investment banking.

Business and Management Structure

Prior to the 1998 merger, Union Bank of Switzerland operated four strategic
business segments:

- private banking and institutional asset management;

- corporate and institutional finance;

- trading, sales and risk management services; and

- retail banking.

Swiss Bank Corporation also operated in four divisions prior to the 1998 merger:

- SBC Private Banking;

- SBC Warburg Dillon Read (investment banking);

- SBC Switzerland (corporate and retail banking); and

- SBC Brinson (investment management).

The combined entity following the 1998 merger initially had the following five
operating divisions and the Corporate Center:

- UBS Private Banking;

- Warburg Dillon Read;

- UBS Private and Corporate Clients;

- UBS Brinson, which was renamed UBS Asset Management; and

- UBS Private Equity.

UBS
--------------------------------------------------------------------------------

On 18 February 2000, UBS regrouped its businesses into the following three main
business groups to align itself as closely as possible to client needs.

- UBS Switzerland, which is now composed of two business units:

        - Private and Corporate Clients: Swiss retail and commercial banking.

        - Private Banking: private banking services offered to all Swiss and
          international high net worth clients who bank in Switzerland or
          offshore centers.

- UBS Asset Management, which now includes:

        - Institutional Asset Management: Brinson Partners and Phillips & Drew
          business areas, which are now integrated to form a single global
          investment platform.

        - Investment Funds/GAM: The Investment Funds and Global Asset
          Management, or GAM, business areas, transferred from UBS Private
          Banking.

- UBS Warburg, which is now comprised of four business units:

        - Corporate and Institutional Clients: securities and investment banking
          products and services for institutional and corporate clients. This
          includes the Corporate Finance, Equities, Fixed Income and Treasury
          Products businesses.

        - UBS Capital: investment of UBS and third-party funds in a diverse
          range of private, and occasionally public, companies on a global
          basis.

        - Private Clients: UBS's onshore private banking services for high net
          worth individuals worldwide, outside of Switzerland.

        - e-services: personalized investment and advisory services at
          competitive fees for affluent clients in Europe, delivered via a
          multi-channel structure that integrates internet, call centers and
          investment centers.

UBS's board of directors, which consists exclusively of non-executive directors
in accordance with Swiss Banking Law, has the ultimate responsibility for the
strategic direction of UBS's business and the supervision and control of
executive management. The Group Executive Board, which is UBS's most senior
executive body, assumes overall responsibility for the development of UBS's
strategies and its implementation and results.

The Chief Executive Officer of each business group is a member of the Group
Executive Board and is responsible and accountable for the results of the
business group as a whole. However, when the new business group structure was
introduced, UBS committed to continue to provide summary financial and
management information about the business units, in order to maintain
transparency in its affairs and allow shareholders to make meaningful
comparisons to the performance of the Group under its previous structure.
Therefore, the discussion in this section describes the business groups mainly
in terms of their constituent business units.

In the remainder of this section, the discussion will be divided into the three
business groups and their constituent business units, as they exist now, not the
five divisions as they existed on 31 December 1999.

UBS Switzerland

The UBS Switzerland business group is made up of two business units:

- Private and Corporate Clients -- The leading retail and commercial bank in
  Switzerland.

- Private Banking -- Covers all Swiss and international high net worth clients
  who bank in Switzerland or offshore centers.

The onshore Private Clients business, formerly part of Private Banking, is now
managed within the UBS Warburg business group.

UBS Switzerland is the leading Swiss bank for individual and corporate clients
and a premier Swiss private banking institution. UBS Switzerland offers a
continuum of services to all Swiss-based clients. It benefits from an integrated
infrastructure and the opportunity for shared distribution via its developing
multi-channel architecture.

To drive forward its e-commerce vision and strategy, UBS Switzerland has created
a single business area called "e-Channels and Products" to lead all its
e-banking activities. The new business area will be responsible for all
electronic channels and products as well as associated service and support
centers and will oversee all e-banking functions of UBS Switzerland. Its costs
are shared between Private Banking and Private and Corporate Clients, based on
service level agreements.

Private and Corporate Clients.  The Private and Corporate Clients business unit
of UBS Switzerland is the leading retail bank in Switzerland and targets
individual clients with assets of up to approximately CHF 1 million as well as
business and corporate clients in Switzerland. At 30 June 2000, this business
unit had about CHF 439 billion in assets under management and a loan portfolio
of approximately CHF 163 billion. Private and Corporate Clients employs over
22,000 people in its headquarters in Zurich and its offices throughout
Switzerland.

Set forth below is summary information, based on management accounting data,
relating to the Private and Corporate Clients business unit, which is discussed
in greater detail under "--Management's Discussion and Analysis of Financial
Condition and Results of Operations--Results of Operations by Business Unit--UBS
Switzerland--Private and Corporate Clients."

Organizational Structure.  Private and Corporate Clients operates four main
business areas:

- Individual Clients -- This business area includes over 4,000,000 client
  accounts, of which over 25% are client accounts that relate to clients with
  assets over CHF 50,000.

- Corporate Clients -- This business area focuses on Swiss corporate clients and
  includes 160 top corporations, over 7,500 large corporate clients and 180,000
  small- and medium-sized businesses.

- Operations -- In addition to providing operational support to the retail
  banking business and other Swiss-based UBS units, this business area provides
  payment and custodial services to approximately 1,800 banking institutions
  throughout the world.

- Risk Transformation and Capital Management -- This business area has
  responsibility for clients with impaired or non-performing loans and manages
  the risk in Private and Corporate Clients' loan portfolio. It is also
  responsible for optimizing capital utilization.

Private and Corporate Clients also includes the Resources business area, which
provides real estate, marketing, personnel and administrative services to
Private and Corporate Clients and the other UBS business units in Switzerland,
particularly Private Banking, and the Information Technology business area,
which provides information technology services to Private and Corporate Clients
and the other Swiss-based UBS offices, again with Private Banking as the main
recipient.

Profit Enhancement Initiatives.  The domestic retail banking sector in
Switzerland has historically been a high-cost, low-return business. In order to
further enhance the profitability of the retail business and to exploit the
synergies after the 1998 merger, UBS has developed and commenced a number of
initiatives that are intended to reduce the costs and increase the revenues of
this business unit. These include:

- The further development and enhancement of alternative distribution channels,
  including:

        - UBS e-banking, on-line internet and teletext banking, and telephone
          banking.

        - UBS Multimat and UBS Bancomat Plus, which together offer a direct
          electronic link to the customer's account and to a full range of
          traditional ATM services, including accepting cash deposits, and
          permits additional functions, such as the set-up and maintenance of
          payment and standing orders.

     - Increasing revenue principally through improvements in pricing, increased
       focus on higher yielding investment products and fee-based businesses,
       and improvements in the distribution of UBS's products, including
       implementing risk-adjusted pricing in its new and maturing loan business
       and by expanding its e-banking services.

     - Reducing costs by continuing to close branches. Since the 1998 merger,
       UBS has closed 200 branches, or 36%, still leaving UBS with more branches
       than either predecessor institution.

     - Increasing the efficiency and productivity of Private and Corporate
       Clients' processes by standardizing its products and taking advantage of
       automation and other technological developments.

Clients.  Private and Corporate Clients has a diverse client base, ranging from
individual clients to corporate clients and international banking institutions.
Private and Corporate Clients provides a broad range of products and services to
these clients, including retail banking, investment services and lending. UBS
believes that clients choose Private and Corporate Clients primarily based on
UBS's leading position as a bank and an asset manager in Switzerland, its broad
distribution network and its ability to provide a comprehensive range of
financial products and services. Based on market surveys, over 96% of the Swiss
market readily recognizes the UBS brand, which has a long history and is well
established in Switzerland.

Client/Product Initiatives.  Rapid growth of technology has made available a
number of alternative distribution channels. UBS has offered telebanking since
1985 and, based upon its market research, UBS has the leading position in the
Swiss telebanking market, initiating in excess of one-half of all telebanking
transactions in Switzerland during 1998.

Since 1997, UBS has expanded its product offerings and taken steps to market
additional services to its client base. Key initiatives include:

- The launch of UBS Tradepac, an expanded all-inclusive internet-based offering
  aimed at serving the on-line trading needs of UBS's customers and providing
  access to six international exchanges. As part of UBS Tradepac, UBS has
  established a partnership with Intuit Inc. that has permitted it to introduce
  UBS Quicken, a specially adapted version of the Quicken software that includes
  enhanced financial management functions and adds to the attractiveness of its
  product offering.

- The launch of UBS's small- and medium-sized business enterprises initiative,
  which is intended to respond to the lack of risk capital for small business
  enterprises.

Investment Services.  UBS's investment services for Private and Corporate
Clients are a collaborative effort among:

- UBS Asset Management, which manages the UBS mutual fund portfolio and
  determines the investment strategy for, delivers monthly tactical asset
  allocations to, and manages discretionary mandates of, Private and Corporate
  Clients' institutional clients.

- UBS Warburg, which provides research and access to the securities exchanges.

- UBS Switzerland, which actively markets and distributes investment products to
  its clients after making the appropriate revisions to take into account the
  needs of those clients.

The principal result is a full range of investment options to offer UBS's
clients including those of Private and Corporate Clients.

management by asset class at 30 June 2000 and 31 December 1999 and 1998.

At 30 June 2000, about CHF 107 billion (or 66%) of the CHF 163 billion loan
portfolio in Private and Corporate Clients related to mortgages, of which
approximately 81% were secured by residential real estate. A discussion of UBS's
loan portfolio classified by industry is included under "--Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Selected Statistical Information--Loans."

Private and Corporate Clients' impaired loans, which include non-performing
loans, are transferred to the Risk Transformation and Capital Management
business area to be managed by UBS's Recovery Group, which specializes in
working-out or otherwise recovering the value of those loans. At 30 June 2000,
Private and Corporate Clients' loan portfolio included approximately a CHF 18
billion recovery portfolio. Approximately CHF 16 billion of Private and
Corporate Clients' 30 June 2000 recovery portfolio was impaired and related to
provisional positions and positions stemming back to weakness in the Swiss
commercial real estate markets during the 1990s. A provision of CHF 9 billion
has been established against the portion of impaired loans not secured by
collateral or otherwise deemed uncollectible. Approximately CHF 2 billion of
UBS's 30 June 2000 recovery portfolio is performing and unimpaired. The
unimpaired loans included in UBS's recovery portfolio are outstanding with
counterparties for whom other loans have become impaired. No provisions have
been established against these loans. UBS's lending officers actively manage the
recovery portfolio, seeking to restructure the lending relationship with a goal
of removing the loan from the recovery portfolio. The following table describes
the development in UBS's recovery portfolio from 1 January 1998 to 30 June 2000.

</TABLE>

Approximately 60% of the loans that were originally included in UBS's recovery
portfolio in 1997 have been worked out and removed. See "--Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Analysis of Risks--Credit Risk" for a further description of UBS's
process for credit risk management and control and a discussion of impaired and
non-performing loans.

Private and Corporate Clients' continued implementation of "risk-adjusted
pricing," which differentiates loan pricing based on risk profiles, has led to
improved margins on UBS's lending portfolio and has resulted in more effective
use of UBS's capital. For a discussion of UBS's credit approval process and how
UBS manages interest rate risk, see "--Management's Discussion and Analysis of
Financial Condition and Results of Operations--Asset and Liability
Management--Interest Rate Management."

The credit approval activities of Private and Corporate Clients are the
responsibility of the business area, coordinated by a separate chief credit
officer who is accountable to the Chief Credit Officer, or "CCO." Generally,
loans are approved by a credit officer who does not participate in the client
relationship, but works with the lending officer to establish a set of lending
criteria that are applicable to the risk profile rating of the borrower. The
exception is for certain high-risk lending relationships, in which case the
credit officer directly corresponds with the borrower. Private and Corporate
Clients' chief credit officer reviews the business area's loans on a periodic
basis (annually for most loans and at least quarterly for high-risk loans) to
confirm the ratings. The CCO further coordinates Private and Corporate Clients'
lending activities and credit exposure with the lending activities and credit
exposure of UBS Warburg and the remainder of UBS Switzerland.

Private Banking.  UBS is one of the leading international private banks, as
measured by assets under management. At 30 June 2000, Private Banking had CHF
683 billion in assets under management. Private Banking serves high net worth
individuals with a broad range of comprehensive wealth management services and
financial products. Private Banking's approach is to focus on establishing
long-term client relationships and emphasizing the life-time value of these
relationships.

The private banking industry is in the process of undergoing some fundamental
changes resulting from the changing profile of high net worth individuals,
emerging technologies and increased competition. Clients are increasingly taking
a more active role in managing their wealth and are demanding more sophisticated
products and a broader geographic range of services. They are focused on asset

performance and allocation, quality of information and advice and extended
availability of services, such as 24-hour, remote and internet access. The
private banking industry is also experiencing an increase in the wealth that
remains in onshore markets, particularly in the form of equity and equity-linked
investments, as domestic capital markets become more developed and generate
higher returns.

To address this changing environment, Private Banking is seeking to further
penetrate its existing client base with enhanced wealth management solutions.
Private Banking's size provides it with the flexibility to offer its clients
customized and expanded service offerings tailored to their particular needs. To
further increase its assets under management in its private banking business,
UBS will also continue to consider select acquisition opportunities that may
arise, as evidenced by the acquisition in 1999 of Bank of America's
international private banking activities. Set forth below is summary
information, based on management accounting data, relating to the Private
Banking business unit of UBS Switzerland, which is discussed in greater detail
under "--Management's Discussion and Analysis of Financial Condition and Results
of Operations--Results of Operations by Business Unit--UBS Switzerland--Private

Marketing and Distribution.  Private Banking provides wealth management services
to its clients in a number of geographic regions and seeks to tailor its service
offerings to meet the specific needs of particular client segments and markets.
To better understand the needs of its existing and prospective clients, Private
Banking differentiates its clients by geographic location and the amount of
assets under management and then based on their product needs and utilization
and service requirements. The client advisors who serve Private Banking's
clients are principally organized by client market, which allows them a higher
level of client focus. Private Banking believes that this approach fosters
valued long-term client relationships.

Private Banking's client advisors retain primary responsibility for introducing
products and services to its existing and prospective private banking clients.
The business areas that deal directly with clients are generally responsible for
their own marketing activities. The client advisors are central to the delivery
of services to Private Banking's clients and are responsible for increasing the
penetration of Private Banking service offerings within its existing customer
base. The client advisors are supported by a separate marketing department,
which is responsible for market research and the preparation of standardized
marketing materials.

Products and Services.  Private Banking provides a number of asset-based,
transaction-based and other services to its clients. Asset-based services
include custodial services, deposit accounts, loans and

fiduciary services while transaction-based services include trading and
brokerage and investment fund services. Private Banking also provides financial
planning and consulting and offers financial planning instruments to its
clients. These services include establishing proprietary trusts and foundations,
the execution of wills, corporate and personal tax structuring and tax efficient
investments. Private Banking has the following three core product and service
business areas:

     - Financial Planning and Wealth Management -- Responsible for developing
       integrated comprehensive wealth management services in the form of tax
       and estate planning, liquidity and retirement lifestyle planning,
       insurance products, art and real estate advisory services and a variety
       of sophisticated capital enhancement and asset protection strategies.

     - Portfolio Management -- Responsible for providing portfolio management
       services to Private Banking clients and for the investment clients of
       Private and Corporate Clients.

     - Active Advisory Team -- Provides sales brokerage, investment advisory
       services and products to key private banking locations worldwide. The
       Active Advisory Team provides information concerning, and facilitates
       investments in, primary initial public offerings and secondary
       placements. This team also provides fiduciary services and the execution
       of private banking orders outside Switzerland.

At 30 June 2000, slightly more than one-fifth of Private Banking's assets under
management were managed on a discretionary basis. The remaining assets under
management related to advisory engagements.

     UBS Asset Management

UBS Asset Management brings together UBS's asset management activities. It
consists of two business units:

     - Institutional Asset Management -- One of the largest institutional asset
       managers in the world.

     - Investment Funds/GAM -- Investment Funds is one of the leading funds
       providers in Europe and the seventh largest in the world. GAM is a
       diversified asset management group with assets composed primarily of
       private client accounts, institutional and mutual funds.

UBS Asset Management benefits from an integrated business model and single
management team.

Institutional Asset Management.  Based on assets under management, Institutional
Asset Management is one of the largest institutional asset managers in the world
and among the industry leaders in the United States, the United Kingdom and
Switzerland. At 30 June 2000, Institutional Asset Management had over CHF 525
billion in assets under management, including CHF 326 billion of institutional
assets and CHF 199 billion of non-institutional assets, including the UBS
Investment Funds offered by the Investment Funds business area of the Investment
Funds/GAM business unit, which are managed by Institutional Asset Management.
Institutional Asset Management is headquartered in Chicago and has offices in
Dallas/Houston, Frankfurt, Geneva, Hartford, Hong Kong, London, Melbourne, New
York, Paris, Rio de Janeiro, San Francisco, Singapore, Sydney, Tokyo and Zurich.

Institutional Asset Management markets its services under the UBS Asset
Management name, with Brinson Partners and Phillips & Drew serving as sub-brands
within the Americas and the United Kingdom, respectively. Institutional Asset
Management believes that its broad geographic spread of operations and strong
brand names will help it pursue growth opportunities in Continental Europe,
Asia-Pacific and Latin America and maintain its strong positions in the mature
markets it serves in the United States, the United Kingdom and Switzerland.

Set forth below is summary information, based on management accounting data,
relating to Institutional Asset Management, which is discussed in greater detail

accountability for results and the business group's effectiveness and
efficiency. At 30 June 2000, Institutional Asset Management's organizational
structure consisted of the following business areas:

- Brinson Partners and Phillips & Drew -- These business areas have the mandate
  to optimize the contribution from the Americas and the United Kingdom,
  respectively, and to further develop their investment capabilities and to
  contribute to global business development efforts in Europe and the
  Asia-Pacific region.

- Europe, Middle East & Africa and Asia Pacific -- These two business areas have
  a mandate to capture profitable growth opportunities in their assigned
  geographic markets and to optimize the contribution from existing businesses
  in these regions. These mandates strengthen the regional accountability for
  results and resources. At the same time, both regional business areas continue
  to contribute to the UBS Asset Management global investment process as well as
  ensure their adaptation to regional client needs where appropriate.

- O'Connor -- Launched at the beginning of June 2000, O'Connor is comprised of
  part of the proprietary equity trading group of UBS Warburg, as well as the
  Fund of Funds and Currency Funds businesses of UBS Warburg. O'Connor will
  focus on alternative investments, or investment strategies designed to provide
  attractive risk-adjusted returns with a low correlation to traditional
  investments.

- IT and Operations -- This business area is responsible for implementing and
  maintaining information technology and delivery platforms for the
  Institutional Asset Management business unit.

Clients.  Institutional Asset Management has a diverse institutional client base
located throughout Europe, the Middle East, Africa, the Asia-Pacific region and
the Americas. Its clients consist of:

- corporate and public pension plans;

- endowments and private foundations;

- insurance companies;

- central banks and supranationals; and

- financial advisers.

Externally managed pension assets constitute the majority of worldwide available
institutional assets. The pension market is undergoing a shift from traditional
defined benefit plans to defined contribution schemes. One of Institutional
Asset Management's strategic initiatives is to position itself to take advantage
of the opportunities created in this changing environment.

The following table shows assets under management broken down between
institutional assets and non-institutional assets at 30 June 2000 and 31
December 1999 and 1998. Non-institutional assets include the UBS Investment
Funds, which are managed by Institutional Asset Management.

Marketing and Distribution.  Clients differentiate among institutional asset
managers based on client service, investment performance, process and
philosophy, fees and continuity of staff. Institutional Asset Management seeks
to use its long-term track record and strong client franchise to increase the
penetration of its services with both new and existing clients. It is a full
service institutional asset management firm, offering its clients a
comprehensive range of research and investment analysis as part of its overall
service and capability package.

Consultants advise institutional investors based on their expert knowledge of
managers' investment performance, process and client service capabilities, as
well as other factors. In consultant-driven markets, such as the United States
and the United Kingdom, Institutional Asset Management relies on its strong
relationships with the major consultants that advise corporate and public
pension plans, endowments, foundations, and other institutions. It also
dedicates resources to generating new business directly with large clients.

Institutional Asset Management also seeks to increase its revenues from existing
clients. Each of its client-facing business areas has dedicated account
management teams that service existing clients and seek to find new ways to
address client needs. These account managers are also focused on further
developing and solidifying the relationships that Institutional Asset Management
has with the major consultants that serve its clients.

Client Mandates.  Institutional Asset Management seeks to deliver sustained
value-added investment performance relative to client-mandated benchmarks. Its
client mandates range from fully discretionary global asset allocation
portfolios to equity or fixed income portfolios with a single country emphasis
to other asset classes, including real estate, timber, oil and gas, and private
equity. These portfolios are available through separately managed portfolios as
well as through a comprehensive range of pooled investment funds.

Institutional Asset Management by client mandate at 30 June 2000 and 31 December
1999 and 1998.

any particular segment. For example, within the equity, asset allocation and
fixed income areas, it offers a range of mandates on global, regional, emerging
market and sector-specific bases. The private markets category includes such
mandates as direct investments, oil and gas, partnership investments, real
estate and timber.

Investment Process and Research.  At the beginning of March 2000, Institutional
Asset Management announced that Brinson Partners and Phillips & Drew were being
combined to establish a common global investment management platform. This
decision reflected the shared investment philosophies of Phillips & Drew and
Brinson Partners, based on capturing price-value discrepancies identified
through fundamental research as well as similar cultures. The initial
integration was completed according to schedule at the beginning of May 2000.

The investment process is based on Institutional Asset Management efforts to
determine and quantify investment value. Senior investment professionals set
policy and oversee research activity within the units, drawing upon the
expertise of investment specialists in each asset class. These specialists
consult with external analysts, economists, consultants and academics. They
develop research and provide input into Institutional Asset Management's
quantitative valuation models. Institutional Asset Management estimates
long-term expected returns for asset classes, markets, and securities using
proprietary valuation models that consider cash flows discounted at
risk-adjusted rates and then evaluates potential strategies in the context of
forecasted returns as well as its forecasted risks and correlations.

Institutional Asset Management creates portfolios and monitors and adjusts them
based on relative price/value discrepancies. Its method is to identify periodic
discrepancies between market price and investment value and turn them to its
clients' advantage. Where no significant discrepancies exist between price and
value, Institutional Asset Management continues its research and analysis.
Institutional Asset Management believes that its approach allows it to respond
to market changes, while providing its clients with the benefit of its knowledge
and experience and maintains the flexibility to customize portfolios to meet
their requirements.

Investment Funds/GAM.  As part of the re-grouping announced in February 2000,
the Global Asset Management, or GAM, and Investment Funds areas of the former
Private Banking division were transferred to UBS Asset Management, bringing
together all of UBS's asset management activities.

UBS Asset Management will benefit from an integrated business model and single
management team. Within this framework GAM will be distinctly positioned and
maintain its brand identity as well as its unique investment styles.

Set forth below is summary information, based on management accounting data,
relating to the Investment Funds/GAM business unit, which is discussed in
greater detail under "--Management's Discussion and Analysis of Financial
Condition and Results of Operations --UBS Asset Management--Investment
Funds/GAM."

Investment Funds.  As a result of the merger between the Union Bank of
Switzerland and Swiss Bank Corporation, Investment Funds became the leading
investment fund provider in Europe and Switzerland in terms of investment fund
assets under management. By year-end 1999, Investment Funds' assets under
management increased 15% with growth primarily attributable to investment
performance. UBS has received numerous awards, including being named
"Switzerland's Best Overall Management Group" by Standard & Poor's Fund Services
in 1999.

Marketing and Distribution.  Investment Funds are distributed primarily through
UBS Switzerland and UBS Warburg, with a minority of assets distributed through
third-party distribution partners. As of 30 June 2000, Investment Funds had CHF
203 billion in assets under management, including CHF 9.2 billion in assets
under management distributed through third-party distribution partners. In
addition, Investment Funds has a significant business administering assets for
third-parties.

As part of the Group reorganization, Investment Funds is evolving towards an
open, multi-channel distribution architecture. Initiatives include establishing
additional third-party distribution partnerships, developing electronic sales
channels and combining distribution efforts with Institutional Asset Management
in various markets to better capture defined contribution opportunities.
Additionally, the Investment Funds business unit is currently developing an
e-based investment fund distribution strategy. This channel will offer clients
personalized advisory services, investor education content, online decision
support tools, and automated trade execution, delivered through intermediaries.

The continuing trend toward equity investments helped increase equity funds by
75% since the end of 1998, making Equity Investment Funds' largest asset
category, accounting for 31% of total Investment Funds volume. The number of
Investment Fund accounts, which make it easy for clients to make regular savings
in UBS Investment Funds, has grown by 80% to 90,000, with assets invested
through them increasing by 39% to a total of CHF 2.5 billion in 1999.

Investment Process and Research.  The Institutional Asset Management business
unit is responsible for managing the investment funds offered by the Investment
Funds business unit, other than some real estate funds. However, Investment
Funds is responsible for managing its product range, which is tailored to meet
the needs of individual investors, and for the development and marketing of
individual funds.

Global Asset Management.  Acquired in late 1999, Global Asset Management, or
"GAM," is a diversified asset management group with approximately 600 employees
and operations in Europe, North America, Asia and the Middle East. It manages
assets comprised of private client portfolios and over 170 private client mutual
funds, as well as institutional mandates. GAM continues to operate under its
established brand name within UBS Asset Management and continues to employ its
own distinctive investment style.

UBS Asset Management will increasingly take advantage of GAM's range of mutual
funds and its multi-manager selection process, in which it selects the top 90
out of about 6,000 third-party fund providers, to enhance the range of its
investment styles and products.

Marketing and Distribution.  Marketing and distribution for GAM is divided into
three areas: Private Clients, Mutual Funds and Institutional. Each area markets
and services clients within its specific segment.

-  Private Clients -- Offers and manages a broad range of tailored investment
   strategies for its clients across the risk/return spectrum and from all major
   reference currency perspectives. Implementation is through a combination of
   GAM funds, under guidance established by GAM's investment committee.

   The private client area seeks clients from a variety of sources including
   referrals from its existing client base, intermediaries, and professional
   advisors. Clients receive a high level of service from a dedicated team of
   portfolio managers. Communication is ongoing and includes regular formal
   review meetings.

-  Mutual Funds -- GAM distributes mutual funds on a global basis, including
   within the United States. GAM's Mutual Funds area seeks clients at the high
   end of the market. Mutual funds are

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

UBS
--------------------------------------------------------------------------------

   distributed through multiple channels, including brokerage firms, banks,
   portfolio and fund managers, financial advisors, family offices, employee
   pension plans, and directly to major investors.

-  Institutional -- GAM provides a full range of services to its institutional
   clients through dedicated account managers. Institutions are offered the same
   products developed to support GAM's private client and fund distributions
   businesses. This includes traditional equity portfolio management, as well as
   multi-manager funds and alternative assets classes.

Investment Process and Research.  GAM was founded in 1983 to give private
clients "access to great investment talent." As a result, the investment process
is based on selecting the world's leading investment talent, whether the manager
selected for a particular fund or mandate is internal to GAM or an external
manager. Beginning in 1989, GAM extended its investment process to pioneer the
development of the multi-manager concept.

An in-house team of investment professionals is responsible for managing the
various internally managed mandates or funds. Members of this team also create
multi-manager mandates using a quantitative database of 50,000 funds, and by
carefully scrutinizing all aspects of external managers employing a qualitative
database of 6,000 investment managers. The investment objective of multi-
manager funds or mandates is diversifying risk by employing complementary
managers using different strategies.

The range of funds and mandates extends from traditional equity and bond funds
to a comprehensive range of alternative investment funds.

UBS Warburg

UBS Warburg is composed of four business units:

-  Corporate and Institutional Clients -- Securities and investment banking
   products and services for institutional and corporate clients.

-  UBS Capital -- Investment of UBS and third-party funds in a diverse range of
   private, and occasionally public, companies on a global basis.

-  Private Clients -- Onshore private banking services for high net worth
   individuals worldwide, outside of Switzerland.

-  e-services -- Personalized investment and advisory services at competitive
   fees for affluent clients in Europe, delivered via a multi-channel structure
   that integrates internet, call centers and investment centers.

Corporate and Institutional Clients.  The Corporate and Institutional Clients
business unit is one of the leading global investment banks. It provides
wholesale financial and investment products and advisory services globally to a
diversified client base, which includes institutional investors (including
institutional asset managers and broker-dealers), corporations, sovereign
governments and supranational organizations. Corporate and Institutional Clients
also manages cash and collateral trading and interest rate risks on behalf of
UBS and executes the vast majority of UBS's retail securities, derivatives and
foreign currency exchange transactions. Corporate and Institutional Clients's
headquarters are in London and, at 30 June 2000, it employed about 13,000 people
in over 40 countries throughout the world.

In the 1998 merger, the investment banking businesses of the two banks came
together to form what is now the Corporate and Institutional Clients business
unit. Within Union Bank of Switzerland, securities trading began in New York and
London in the 1970s and grew in the 1980s with the

Business Areas.  At 30 June 2000, Corporate and Institutional Clients operated
four main business areas that have been organized by the type of products and
services offered and their risk exposure. These four business areas consist of
Equities, Fixed Income, Corporate Finance and Treasury Products. The Corporate
Finance business area works with the Equities and Fixed Income business areas
through the Equity Capital Markets Group, the Debt Capital Markets Group and
Leveraged Finance to originate new equities capital markets business, fixed
income capital markets business and leveraged finance business. Consequently,
operating income from the Equity Capital Markets Group is shared between
Equities and Corporate Finance and operating income from the Debt Capital
Markets Group and Leveraged Finance is shared between Fixed Income and Corporate
Finance. The table below sets forth the operating income before credit loss
expense attributable to each of Corporate and Institutional Clients's main
business areas for the years ended 31 December 1999 and 1998:

e-commerce/Product Initiatives.  The institutional client business worldwide is
rapidly moving to an electronic basis. UBS believes Corporate and Institutional
Clients is well positioned to capitalize on this trend. Recent e-commerce
initiatives include:

     -  Investment Banking On-Line (IBOL).  IBOL provides extensive client
        desktop capability from a single home page with direct access to prices,
        research, trade ideas and analytical tools for Corporate and
        Institutional Clients' equities, fixed income and treasury products
        businesses. Corporate and Institutional Clients delivers electronic
        research to over 5,000 clients and has signed up over 10,000 users. UBS
        intends to expand IBOL to include wireless and video links.

     -  Electronic Transactions for Securities (ETS) and Electronic Transactions
        for OTC Products (ETOP).  ETS and ETOP provide a further rollout of
        on-line order routing and trading capabilities for all securities,
        foreign exchange and derivatives products. 30% of all institutional
        orders are sent via the internet and 90% of all retail orders are
        executed using straight through processing, or "STP."

     -  Corporate Finance On-Line (CFOL).  The CFOL initiative is intended to
        establish a secure connection for the exchange of transactional and
        pricing information with corporate clients to support the execution and
        origination of advisory mandates, as well as to create on-line
        connectivity for capital markets participants.

     -  Debtweb.  Using Debtweb, about 25% of all new bond issue volume in the
        first quarter of 2000 volume was delivered on-line.

     -  DealKey.  Designed for primary equity investors, it uses the web as an
        additional channel for the distribution of value-added information
        relating to current equity and equity-linked offerings.

     -  Transactional Websites.  UBS has established transactional websites for
        euro commercial paper and euro medium-term notes, including consolidated
        site information links to euro credit markets, credit indices and bond
        analytics.

     -  New Web Services.  Other new web services include:

        -  KeyLink Web, which provides secure international electronic banking
           for cash, foreign exchange and securities;

        -  Adviser Web, which relates to Australian equities; and

        -  Global eHelp Service Desk, which provides support for clients 24
           hours a day, 6 days a week.

Providing superior advice and maintaining contacts with clients will be key to
Corporate and Institutional Clients' future success. UBS believes its e-commerce
initiatives will enhance its ability to add value to clients, as well as allow
it to extract value from the processing power and scale of its core business
processes and development standards, in order to maximize the benefits it can
achieve from technological innovations. Corporate and Institutional Clients
already processes 100,000 domestic and cross-border securities trades per day
automatically, and has the capacity to increase this amount five-fold within the
existing infrastructure.

Loan Portfolio.  In 1998, UBS decided that Corporate and Institutional Clients'
loans and commitments that were (1) not part of the loan trading portfolio, (2)
not issued in conjunction with leveraged finance transactions or (3) not
directly supporting its core client relationships, would be separated from the
core activities of Corporate and Institutional Clients and wound down. As a
result of this initiative, Corporate and Institutional Clients' total loans and
committed and undrawn lines of credit have been reduced.

The following table sets forth information regarding the Corporate and
Institutional Clients loan portfolio before allowance for loan loss at 31
December 1999 and 1998.

UBS Capital.  The UBS Capital business unit of UBS Warburg is the private equity
business of UBS.

UBS Capital has increased the value of its investments substantially in recent
years with the book value of its investments increasing from about CHF 400
million at 31 December 1994 to about CHF 3.8 billion at 30 June 2000.

Until earlier this year, UBS Capital was managed as an independent division
within UBS. Following UBS's realignment, UBS Capital now operates within the UBS
Warburg business group. This is expected to further strengthen the business
synergies between the investment banking and private equity businesses, while
maintaining strong links between UBS Capital and UBS Switzerland.

UBS Capital has a local presence throughout major industrialized regions in
Europe, North America, Latin America and the Asia-Pacific region, with about 113
employees as of 30 June 2000. UBS Capital has offices in London, Zurich, New
York, Sao Paolo, Buenos Aires, Paris, The Hague, Munich, Milan, Singapore, Hong
Kong, Seoul, Sydney and Tokyo.

As a private equity group, UBS Capital's business involves investing in unlisted
companies, managing these investments over a medium-term time horizon to
increase their value, and "exiting" the investment in a manner that will
maximize the capital gain. UBS Capital seeks to make both majority and minority
equity investments in established and emerging unlisted companies, either with
UBS's own capital or through sponsored investment funds. Although the main focus
of UBS's investments is late-stage financing, such as management buyouts,
expansion or replacement capital, a minority of the portfolio targets early
stage investments in the technology and telecommunications sectors. UBS Capital

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

UBS
--------------------------------------------------------------------------------

generally targets medium-sized businesses with enterprise values in the range of
CHF 75 million to CHF 1.5 billion.

In addition to its international specialization, UBS Capital endeavors to
differentiate itself from its competitors by creating and adding value by
working together with an investee company's management over a three- to six-year
period to develop the business and optimize the company's performance.

Set forth below is summary information, based on management accounting data,

Competitive Position.  Superior returns and the widespread recognition of
private equity as an alternative asset class has led to a substantial growth in
the number of private equity funds raised in recent years. The number and amount
of private equity funds raised has exceeded the number and amount of attractive
and available private equity investments. This has led to increased competition
among investment banks, investment funds and insurance companies and decreased
returns for private equity investors.

In spite of the changing environment, UBS believes that opportunities for
profitable investment will continue to arise in the private equity business. UBS
believes this potential will be enhanced by a number of factors working in
combination to produce a favorable business environment for astute market
participants. These factors include the introduction of the euro, the worldwide
trend of industrial consolidation, a growing awareness of the importance of
shareholder value and the increasing need to solve succession issues in
family-owned businesses.

Organizational Structure.  UBS Capital is structured on a country and sector
approach and, as of 30 June 2000, had fourteen individual teams covering around
30 countries. UBS believes that UBS Capital's established local presence and
expertise, coupled with the global reach of its operations, generates the early
identification of opportunities and their timely and effective development.

UBS Capital's teams are divided geographically between Western Europe, Asia and
the Americas, which includes Latin America. UBS Capital's presence in the
Asia-Pacific region started in Singapore and now includes Australia and its new
offices in South Korea and Hong Kong.

Last year, UBS Capital established two private equity investment funds in the
Americas. One of these investment funds makes private equity investments
primarily in North America, while the other

investment fund makes private equity investments in Latin America. UBS is the
largest beneficial investor in each of the North America and Latin America
funds.

In connection with the establishment of the new funds, UBS and the team managing
the investments of UBS Capital in the Americas formed two limited liability
company advisors, one to advise each fund. Each fund's advisor is jointly owned
by the managers and principals of the management team and by UBS. Effective 31
December 1999, the managers and principals of the management team resident in
the United States are no longer employed by UBS and are not employed by either
advisor. The remaining employees of UBS Capital in the Americas are either
members or employees of the respective advisors.

Investment Portfolio.  UBS Capital's investment portfolio had a book value of
approximately CHF 3.8 billion and an estimated fair value of approximately CHF
5.2 billion at 30 June 2000. To augment its competitive strengths, UBS Capital
plans to gradually increase its annual investment rate, targeting a portfolio
book value of CHF 5 billion in committed capital from UBS and CHF 5 billion from
third parties.

UBS Capital has designed its portfolio to reduce UBS's exposure to risk by:

- geographically diversifying its portfolio and minimizing concentration of
  investment in specific locations;

- diversifying by industry sector to obtain a good mix between manufacturing and
  services sectors;

- investing a minority of the portfolio in earlier stage growth opportunities,
  such as technology and telecommunications; and

- focusing on later-stage investments, such as management buy-outs of existing
  businesses.

The following table provides information regarding UBS Capital's investment
portfolio by geographic region, by industry sector and by age of investment at
30 June 2000 and 31 December 1999 and 1998.

Investment opportunities originate from a variety of sources, including from UBS
Switzerland and UBS Warburg. UBS Capital's investment policy concentrates on
five "value drivers":

-  negotiate an attractive entry price;

-  increase the company's efficiency;

-  implement a sales growth strategy;

-  repay company debt and reduce leverage; and

-  achieve an exit at a higher multiple than the entry price, or what UBS
   Capital calls "multiple arbitrage."

Where appropriate, UBS Capital tries to participate actively with the management
of its investee companies in developing their businesses over the medium term
(three to six years) in order to optimize their performance. UBS Capital's exit
strategies for the businesses include direct sales to strategic buyers, initial
public offerings, leveraged recapitalizations and sales to other financial
sponsors.

More recently, given the industry trend toward larger sized transactions, UBS
Capital has also begun to concentrate on the formation of four regional
funds -- Europe, North America, Latin America and Asia -- including the two
investment funds in the Americas referred to above. In late 1999, UBS Capital
launched the $1 billion investment fund targeting North America to which it has
committed up to $500 million. In late 1999, UBS Capital also launched the $500
million fund targeting Latin America, which UBS has committed to fund fully with
the option to permit third-party investors to commit up to 25% of such funds. In
addition to these funds, two new funds were launched in Europe during 1999.
Phildrew Ventures V, a United Kingdom private equity fund with a fund size of
GBP 330 million, and CapVis Equity Partners, which is Switzerland's largest
private equity fund with a fund size of CHF 300 million. Phildrew Ventures is
UBS Capital's vehicle for investing in the United Kingdom and Ireland and CapVis
Equity Partners is UBS Capital's vehicle for investing in Switzerland and
Austria. A European fund and an Asian fund are expected to be launched in the
near future.

Private Clients.  UBS Warburg's Private Clients business unit provides onshore
private banking services for high net worth individuals in key markets
worldwide.

Private Clients' target markets include Germany, France, Italy, Spain, the
United Kingdom, the United States, Japan, Australia and Taiwan.

Private Clients had CHF 37 billion of assets under management at 30 June 2000
and 1,277 employees. In the first half of 2000, Private Clients earned revenues
after credit loss expense of CHF 133 million.

The business is mainly in the relatively early stages of start-up operations
and, with the exception of Germany and Australia, where the businesses are based
around an established private bank and an existing domestic brokerage business,
Private Clients' franchise is small.

Organizational Structure.  The offshore Private Clients business was moved to
UBS Warburg in February 2000. UBS Warburg aims to take advantage of the
considerable growth potential resulting from putting investment banking and
investment services activities for private clients under one roof.

The decision to bring Private Clients and the e-services business, described
below, closer together offers many potential synergies including the ability to
enrich the private banking offering with a full complement of online investment
information and execution capabilities. Significant savings are possible in the
medium term from a shared information technology platform as well as shared
operations and infrastructure and a coordinated sales and distribution process.

Products and Services.  Private Clients will focus on delivering a sophisticated
product offering to its high net worth client base, including the specifically
targeted executive and entrepreneur segments. Traditional private banking
services will be combined with investment banking innovation. For example,
Private Clients will further develop its innovative products allowing clients to
release value from own-company shareholdings or options.

UBS believes that on-line capabilities should be an integrated part of the
service offering. As such, the e-services initiative described below, which will
target affluent, advice-seeking private investors, is moving towards an
integrated product and infrastructure approach with Private Clients in Europe.

Private Clients also will increasingly collaborate with UBS Warburg's Corporate
Finance team for client introductions and support on clients' corporate needs.

e-services.  e-services is a new business initiative started in the third
quarter of 1999. e-services intends to offer personalized investment and
advisory services targeted at affluent European individuals, and will be
launched progressively in Germany and thereafter in the United Kingdom and other
European countries, starting in late 2000. e-services plans to implement an
integrated multi-channel "clicks and mortar" distribution concept, including
online channels, call centers and investment centers. e-services had 226
employees at 30 June 2000.

e-services intends to deliver a distinctive set of services, including advanced
financial planning and asset allocation, and investment products such as UBS and
third-party funds, securities and pension products.

Organizational Structure.  e-services continues to build its organizational
structure and establish critical elements of its infrastructure, marketing
approach and product offering. The infrastructure component has long lead times
and e-services has made significant progress. e-services has formed major
alliances with major information technology vendors, including Siebel Systems
Incorporated, Broadvision Incorporated and Artificial Life Incorporated, which
have accelerated time-to-market considerably.

e-services has completed the full deployment of its technical platform and
software infrastructure and has established customer call centers in Edinburgh,
Scotland and Maastricht, Holland.

Total expenditures for e-services were CHF 144 million in the first half of 2000
and are expected to reach CHF 310 million this year, and comparable amounts over
the next few years, although future costs will depend on the exact roll-out
schedule, and the possibility of partnering to share cost. e-services does not
expect to record revenues until 2001.

Target Clients.  e-services will target advice-seeking, affluent investors in
major European markets. The value proposition is tailored to investors with a
need for quick access, quality advice and flawless execution. The business will
use online channels, telephone service centers and investment centers to provide
multi-channel client service.

Products and Services.  The e-services product offering will be based around a
central cash management account, with capabilities for a broad base of products,
services and advice using a sophisticated array of tools covering financial
planning, financial analysis, asset allocation and decision support.

                                                                              39

UBS
--------------------------------------------------------------------------------

e-services is adopting an open architecture model, integrating and distributing
third-party content where this will enrich the service offering.

Marketing and Distribution.  A key focus on acquiring clients will be directed
at establishing deeper relationships with intermediaries and aggregators.

These companies, be they full-service brokers, online discount brokers, online
banks, private banks or independent financial advisors, are increasingly faced
with greater demands for investment services and products in an intensively
competitive environment. UBS is strongly positioned to act as a lead supplier of
content, products, platforms and market access to these companies. Through this
channel UBS expects to be able to increase its order flow, generate incremental
revenues, improve its understanding of the mass market segment, and further
brand UBS Warburg as a leading supplier of investment advisory content and
investment products.

Corporate Center

In the context of a global integrated investment services firm, the role of
Corporate Center is to contribute to the long-term maximization of shareholder
value by:

-  competitively positioning UBS in growing market places with an optimal
   business model and adequate resources;

-  maintaining an appropriate balance between risk and profit to provide
   financial stability on a Group-wide basis; and

-  ensuring that the divisions, while being accountable for their results,
   operate as a coherent and effective Group with a common set of values and
   principles.

To perform its role, Corporate Center establishes standards and principles to be
applied by the divisions, thereby permitting UBS to minimize staffing levels
within Corporate Center.

The following functions are part of Corporate Center:

-  Group internal audit, which reports directly to the Chairman of the Board of
   Directors in order to ensure its operational independence;

-  functions reporting to the Chief Executive Officer, including human resources
   policies and standards, communications with staff, public and media,
   marketing and brand management, and the Group's general counsel; and

-  functions reporting to the Chief Financial Officer, including risk control,
   credit risk management, financial control and management, Group Treasury,
   Group Strategy and communications with regulators, rating agencies, investors
   and analysts.

Additionally, the Corporate Center plays an active role with regard to funding,
capital and balance sheet management and management of foreign currency
earnings.

Competition

UBS operates in a highly competitive environment in all of its businesses and
markets. Many large financial services groups compete with UBS in the provision
of sophisticated banking, investment banking and investment management services
to corporate, institutional and individual customers on a global basis, while
local banks and other financial services companies, which may be of substantial
size, often provide significant competition within national markets. UBS also
competes with other banks, money market funds and mutual funds for deposits,
investments, and other sources of funds. In

some jurisdictions, many of UBS's competitors are not subject to the same
regulatory restrictions that apply to UBS.

Employees

At 30 June 2000, UBS had 47,744 employees.  Set forth below are the number of
employees of UBS broken down by its eight business units and Corporate Center at

The decrease in headcount in the first half of 2000 was mainly attributable to
the transfer of the Systor business, an IT services provider, from Private and
Corporate Clients to become a venture capital investment of UBS Capital and to
1998 merger-related savings in Private and Corporate Clients. These were partly
offset by increases due to the continuing build up of the e-services business,
which will launch later this year, and to investment in growth initiatives in
the Investment Funds business area.

The increase in headcount in 1999 was mainly attributable to expansion of UBS
Warburg's Private Clients business unit, the onshore private banking business
outside Switzerland, and by the acquisitions of Global Asset Management and
Allegis Realty Investors LLC in December 1999, partially offset by decreases in
UBS Warburg's Corporate and Institutional Clients business unit, relating to the
winding down of non-core businesses and 1998 merger-related reductions.

UBS has not experienced any significant strike, work stoppage or labor dispute
in recent years. UBS considers its relations with employees to be good.

Regulation and Supervision

UBS's operations throughout the world are regulated and supervised by the
relevant central banks and regulatory authorities in each of the jurisdictions
in which it has offices, branches and subsidiaries. These authorities impose
reserve and reporting requirements and controls on banks, including those
relating to capital adequacy, depositor protection and prudential supervision.
In addition, a number of countries in which UBS operates impose additional
limitations on, or that affect, foreign or foreign-owned or controlled banks and
financial institutions, including:

-  restrictions on the opening of local offices, branches or subsidiaries and
   the types of banking and non-banking activities that may be conducted by
   those local offices, branches or subsidiaries;

-  restrictions on the acquisition of local banks or requiring a specified
   percentage of local ownership; and

-  restrictions on investment and other financial flows entering or leaving the
   country.

UBS
--------------------------------------------------------------------------------

Changes in the supervisory and regulatory regimes of the countries where UBS
operates will determine to some degree its ability to expand into new markets,
the services and products that it will be able to offer in those markets and how
it structures specific operations.

The most important jurisdictions that regulate and supervise UBS's activities
are Switzerland, the United Kingdom and the United States.

Regulation and Supervision in Switzerland.  UBS is regulated in Switzerland
under a system established by the Swiss Federal Law Relating to Banks and
Savings Banks of 8 November 1934, as amended, and the related Implementing
Ordinance of 17 May 1972, as amended, or the "FBL." Under the FBL, banks in
Switzerland are permitted to engage in a full range of financial services
activities, including commercial banking, investment banking and funds
management. Banking groups may also engage in insurance activities, but these
must be undertaken through a separate subsidiary.

The FBL establishes a framework for supervision by the Federal Banking
Commission, or "FBC." The FBC implements this framework through the issuance of
Ordinances or Circular Letters to the banks that it supervises. In addition, the
regulatory framework in Switzerland relies on self-regulation through the Swiss
Bankers Association, or "SBA." The SBA issues guidelines to banks on conduct of
business issues. Recent examples of such guidelines include:

-  The Due Diligence Convention, which established know your customer standards
   to protect against money laundering;

-  Risk Management Guidelines for Trading and for the Use of Derivatives, which
   set out standards based on the recommendations on this subject from the Group
   of Thirty, The Basel Committee on Banking Supervision and The International
   Organization of Securities Commissions; and

-  Portfolio Management Guidelines, which set standards for banks when managing
   customers funds and administering assets on their behalf.

Mandatory Annual Audits.  The approach to supervising banks in Switzerland
places a particular emphasis on the role of the external auditor. UBS's
auditors, who must be approved by the FBC to perform this role, are required to
submit an annual report to the FBC that assesses UBS's financial situation as
well as its compliance with the regulations and self-regulatory guidelines that
are applicable to its business. If the audit reveals violations or other
irregularities, the independent auditors must (1) inform the FBC if a correction
is not carried out within a designated time limit or (2) inform the FBC
immediately in the case of serious violations or irregularities. The FBC may
issue directives as necessary to require a bank to address any issues identified
by the auditors and may also appoint an expert to act as an observer of a bank
if the claims of the bank's creditors appear to be seriously jeopardized.

Supervision by the FBC.  Since July 1999, the FBC has established a dedicated
unit called the Large Banking Groups Department which focuses solely on the
supervision of UBS AG and the Credit Suisse Group. The group, which consists of
experts covering all the main business activities in which UBS operates,
supervises UBS directly through regular meetings with management as well as
on-site visits. The group also coordinates the activities of the FBC with those
of UBS's main overseas supervisors as well as with those of the external
auditors.

Capital Requirements.  For purposes of complying with Swiss capital
requirements, bank capital is divided into three main categories:

-  core (or Tier 1) capital,

-  supplementary (or Tier 2) capital, and

-  additional (or Tier 3) capital.

--------------------------------------------------------------------------------
 42
<PAGE>   75
UBS
--------------------------------------------------------------------------------

Tier 1 capital primarily includes paid-in share capital, reserves (defined to
include retained earnings) and capital participations of minority shareholders
in fully consolidated subsidiaries, and is reduced by, among other items, the
bank's holdings of its own shares. Tier 1 capital is supplemented, for capital
adequacy purposes, by Tier 2 capital, which consists of, among other things, two
categories of subordinated debt instruments that may be issued by a bank, and by
Tier 3 capital, which consists of certain subordinated debt obligations. The use
of Tier 2 and Tier 3 capital in complying with capital ratio requirements is,
however, subject to limitations.

Under Swiss law, a bank must maintain a minimum capital ratio of 8%, calculated
by dividing adjusted core and supplementary capital by aggregate risk-weighted
assets. This standard must be met on both a consolidated and an unconsolidated
basis. UBS is required to file a statement of its required and existing capital
resources, together with its annual statement of condition and interim balance
sheet, with both the FBC and the Swiss National Bank.

Liquidity Requirements.  Under Swiss law, banks are required to maintain
specified measures of primary and secondary liquidity. Primary liquidity is
measured by comparing Swiss franc-denominated liabilities to liquid assets in
Swiss francs. For this purpose, liabilities are defined as balances due to
banks, due on demand or due within three months, as well as 20% of deposits in
savings and similar accounts. Under current law, UBS's liquid assets must be
maintained at the level of at least 2.5% of these kinds of liabilities.

To measure secondary liquidity, assets maturing within one month which are
readily marketable and suitable for offsetting are subtracted from the
short-term and suitable for offsetting liabilities due to banks on demand or
maturing within one month, time deposits repayable within one month and certain
other liabilities maturing within one month (such as debentures, cash bonds and
cash certificates). Any excess of such liabilities remaining after this
calculation is then added to the sum of 50% of demand deposits and certain other
deposit accounts that have no restrictions on withdrawal, and 15% of thrift,
deposit and savings book accounts as well as similar accounts that are subject
to restrictions on withdrawal. The total of UBS's liquid and readily marketable
assets must be at least equal to 33% of the short-term liabilities as calculated
above.

UBS is required to file monthly statements reflecting its primary liquidity
position and quarterly statements reflecting its secondary liquidity position.

Disclosures to the Swiss National Bank.  Although the primary responsibility for
supervision of banks under the FBL lies with the FBC, UBS also submits an annual
statement of condition and detailed monthly interim balance sheets to the Swiss
National Bank. The Swiss National Bank may require further disclosures from UBS
concerning its financial condition as well as other information relevant to
regulatory oversight by the Swiss National Bank.

Regulation and Supervision in the United States.

Banking Regulation.  UBS's operations in the United States are subject to a
variety of regulatory regimes. UBS maintains branches in California,
Connecticut, Illinois and New York and agencies in Florida and Texas. UBS refers
to these as its U.S. "banking offices." UBS's California branches are located in
Los Angeles and San Francisco and are licensed by the Office of the Comptroller
of the Currency. Each of UBS's other U.S. banking offices is licensed by the
state banking authority of the state in which it is located. Each U.S. banking
office is subject to regulation and examination by its licensing authority. In
addition, the Board of Governors of the Federal Reserve System exercises
examination and regulatory authority over UBS's state-licensed U.S. banking
offices. None of UBS's U.S. banking offices are insured by the Federal Deposit
Insurance Corporation. The regulation of UBS's U.S. banking offices imposes
restrictions on the activities of those offices, as well as prudential
restrictions, such as limits on extensions of credit to a single borrower,
including UBS subsidiaries.

<PAGE>   76
UBS
--------------------------------------------------------------------------------

The licensing authority of each U.S. banking office has the authority to take
possession of the business and property of the office it licenses in certain
circumstances. Such circumstances generally include violations of law, unsafe
business practices and insolvency. So long as UBS maintains one or more federal
branches, such as its California branches, state insolvency regimes that would
otherwise be applicable to its state licensed offices may be preempted by U.S.
federal law. As a result, if the Office of the Comptroller of the Currency
exercised its authority over UBS's U.S. banking offices pursuant to federal law
in the event of a UBS insolvency, all of UBS's U.S. assets would be applied
first to satisfy creditors of its U.S. banking offices as a group, and then made
available for application pursuant to any Swiss insolvency proceeding.

In addition to the direct regulation of its U.S. banking offices, operating its
U.S. banking offices subjects UBS to regulation by the Board of Governors of the
Federal Reserve System under various laws, including the International Banking
Act of 1978, as amended, and the Bank Holding Company Act of 1956, as amended.
The Bank Holding Company Act imposes significant restrictions on UBS's U.S.
nonbanking operations and on its worldwide holdings of equity in companies
operating in the United States. Historically, UBS's U.S. nonbanking activities
were principally limited to activities that the Board of Governors of the
Federal Reserve System found to be so "closely related to banking as to be a
proper incident thereto." Moreover, prior approval by the Board of Governors of
the Federal Reserve System has been required to engage in new activities and to
make acquisitions in the United States.

The Gramm-Leach-Bliley Financial Modernization Act of 1999 was recently enacted,
liberalizing the restrictions on the nonbanking activities of banking
organizations, including non-U.S. banks operating U.S. Banking Offices. The
Gramm-Leach-Bliley Act:

-  allows bank holding companies meeting management, capital and, in the case of
   companies owning FDIC-insured banks, Community Reinvestment Act standards to
   engage in a substantially broader range of nonbanking activities than
   previously was permissible, including insurance underwriting and making
   merchant banking investments;

-  allows insurers and other financial services companies to acquire banks;

-  removes various restrictions that previously applied to bank holding company
   ownership of securities firms and mutual fund advisory companies; and

-  revised the overall regulatory structure applicable to bank holding
   companies, including those that also engage in insurance and securities
   operations.

This part of the Gramm-Leach-Bliley Act became effective on 11 March 2000. On 10
April 2000, UBS AG was designated a "financial holding company" under the
Gramm-Leach-Bliley Act, which generally permits it to exercise the new powers
granted by that act.

The Gramm-Leach-Bliley Act will also modify other current financial laws,
including laws related to the conduct of securities activities by U.S. banks and
U.S. banking offices. As a result, UBS may relocate certain activities now
conducted by its U.S. banking offices to a UBS subsidiary or elsewhere.

Other.  In the United States, UBS's U.S. registered broker-dealer is regulated
by the SEC as a registered broker-dealer. Broker-dealers are subject to
regulations that cover all aspects of the securities business, including:

-  sales methods,

-  trade practices among broker-dealers,

-  use and safekeeping of customers' funds and securities,

--------------------------------------------------------------------------------
 44
<PAGE>   77
UBS
--------------------------------------------------------------------------------

-  capital structure,

-  record-keeping,

-  the financing of customers' purchases, and

-  the conduct of directors, officers and employees.

In addition, UBS's U.S. registered broker-dealer is a member of and regulated by
the New York Stock Exchange and is regulated by the individual state securities
authorities in the states in which it operates.

These U.S. government agencies and self-regulatory organizations, as well as
state securities commissions in the United States, are empowered to conduct
administrative proceedings that can result in censure, fine, the issuance of
cease-and-desist orders or the suspension or expulsion of a broker-dealer or its
directors, officers or employees. UBS's U.S. commodities-related businesses are
subject to similar regulation.

Regulation and Supervision in the United Kingdom.  UBS operates in the United
Kingdom under a regulatory regime that is undergoing comprehensive restructuring
aimed at implementing the Financial Services Authority as the United Kingdom's
unified regulator. Through 1999, UBS was regulated by the Securities and Futures
Authority Limited in respect of its investment banking, individual asset
management, brokerage and principal trading activities, and by the Investment
Management Regulatory Organization in respect of its institutional asset
management and fund management activities. Commencing in 2000, however, the
responsibilities of the Securities and Futures Authority Limited and Investment
Management Regulatory Organization have been taken over by the Financial
Services Authority. Some of UBS's subsidiaries and affiliates are also regulated
by the London Stock Exchange and other United Kingdom securities and commodities
exchanges of which UBS is a member. The investment services that are subject to
oversight by United Kingdom regulators are regulated in accordance with European
Union directives requiring, among other things, compliance with certain capital
adequacy standards, customer protection requirements and conduct of business
rules. These standards, requirements and rules are similarly implemented, under
the same directives, throughout the European Union and are broadly comparable in
scope and purpose to the regulatory capital and customer protection requirements
imposed under applicable U.S. law.

DESCRIPTION OF PROPERTY

At 30 June 2000, UBS operated about 1,230 offices and branches worldwide, of
which about 82.7% were in Switzerland. Of the remaining 17.3%, 8.6% were in
Europe, 5.8% were in the Americas and 2.9% were in Asia. Approximately 43% of
the offices and branches in Switzerland are owned directly by UBS with the
remainder, along with most of UBS's offices outside Switzerland, being held
under commercial leases. The premises are subject to continuous maintenance and
upgrading and are considered suitable and adequate for UBS's current and
anticipated operations.

LEGAL PROCEEDINGS

Except as described below, there are no legal or arbitration proceedings pending
or threatened of which UBS is aware involving UBS which may have or have had a
significant effect on the financial position of UBS taken as a whole.

In the United States, several class action lawsuits, in relation to what is
known as the Holocaust affair, have been brought against UBS, as legal successor
to Swiss Bank Corporation and Union Bank of Switzerland, in the United States
District Court for the Eastern District of New York (Brooklyn). These lawsuits
were initially filed in October 1996. Credit Suisse Group has been designated as
a defendant

--------------------------------------------------------------------------------
                                                                              45

UBS
--------------------------------------------------------------------------------

alongside UBS. On 12 August 1998, a settlement was reached between the parties.
This settlement provides for a payment by the defendant banks to the plaintiffs,
under certain terms and conditions, of an aggregate amount of $1.25 billion. UBS
agreed to contribute up to two-thirds of this amount.

To the extent that other Swiss companies agreed to participate in this fund, and
to the extent of applicable payments to beneficiaries of eligible dormant
accounts, UBS's share was to be reduced. For these purposes, dormant accounts
are defined as accounts with banks and other financial institutions prior to 9
May 1945 which are part of the settlement agreement. In Switzerland, dormant or
abandoned accounts remain on the books of the bank in perpetuity, until claimed
or settled. Therefore, if such dormant or abandoned accounts are identified as
balances that should be used to fund the settlement, the payment of cash to
claimants causes the account to be liquidated from the company's records,
thereby reducing cash and reducing the dormant account liability, as well as the
remaining settlement amount liability. Accordingly, to the extent that such
accounts are identified at institutions other than UBS, UBS's exposure to this
matter will be reduced. Based on UBS's estimate of such expected contributions,
UBS provided a reserve of $610 million (CHF 842 million) in 1998 and an
additional $95 million (CHF 154 million) in 1999.

During the second quarter of 2000, as part of the continuing review of this
matter, UBS recognized that the amounts in dormant accounts attributable to
Holocaust victims at UBS as well as at other Swiss banks are vastly below the
initially expected level, and that UBS needed to adjust its reserve. In
addition, on 26 July 2000, Judge Korman, the presiding judge in this matter,
approved the settlement agreement. The final settlement approved by the judge
describes a new mechanism to include Holocaust-related insurance claims for
insurance companies. As a consequence, contributions by insurance companies will
not serve to offset the banks' liabilities, contrary to UBS's previous
understanding. As a result, in the second quarter of 2000, UBS provided an
additional reserve of $122 million (CHF 200 million), bringing the total
provision to $827 million (CHF 1,196 million). The difference between the amount
accrued and the maximum potential liability of $833 million represents amounts
specifically identified in UBS's customer accounts that are eligible for offset.

EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS

There are no restrictions under UBS's Articles of Association or Swiss law,
presently in force, that limit the right of non-resident or foreign owners to
hold UBS's securities freely or, when entitled, as described under "Description
of UBS Ordinary Shares--Voting Rights," to vote UBS's securities freely. There
are currently no Swiss foreign exchange controls or laws restricting the import
or export of capital. In addition, there are currently no restrictions under
Swiss law affecting the remittance of dividends, interest or other payments to
non-resident holders of UBS securities.

CONTROL OF UBS

As far as UBS is aware, UBS is neither directly nor indirectly owned nor
controlled by another corporation or any government and there are no
arrangements in place the operation of which may result in a change in control.

As of 31 August 2000, UBS's directors and executive officers as a group
beneficially held 2,368,412 of UBS's issued and outstanding ordinary shares. For
the purposes of this analysis, UBS's executive officers are the members of the
UBS Group Managing Board. The Group Managing Board consists of the seven members
of the Group Executive Board, and 26 members who hold senior positions at the
top level of UBS's organization in the Business Groups and Corporate Center. See
also "-- Options to Purchase Securities from UBS" on page 126 for a discussion
of options and warrants issued by UBS.

DIRECTORS AND OFFICERS OF UBS

The UBS Board of Directors has ultimate responsibility for the strategic
direction of UBS's business and the supervision and control of UBS's executive
management. The Board of Directors consists exclusively of non-executive
directors in accordance with the Swiss Banking Law. Each member of the Board is
elected at the annual general meeting of shareholders for a four-year term.
However, at the initial annual general meeting, the terms varied between one and
four years to provide for staggered terms for Board members. In order to ensure
its independence, the Chief Executive Officer of UBS is not permitted to be a
member of the Board of Directors. The UBS Articles of Association and the UBS
Organizational Regulations prescribe the presentation of information on UBS's
affairs to the members of the Board of Directors.

The UBS Group Executive Board is UBS's most senior executive body. It assumes
overall responsibility for the development of UBS's strategies, and the
implementation of the results of these strategies. The UBS Group Executive Board
is comprised of seven members, namely the UBS Chief Executive Officer, the Chief
Executive Officer of the three Business Groups, the Private Banking business
unit and of UBS Capital, and the UBS Chief Financial Officer. The UBS Group
Executive Board normally convenes bi-weekly. Information concerning the members
of the Board of Directors is set forth in the table below.

COMPENSATION OF DIRECTORS AND OFFICERS

The aggregate compensation paid by UBS to its directors and officers as a group
in 1998 was approximately CHF 102.8 million, including bonus compensation and
approximately CHF 10.3 million in accrued pension benefits. The aggregate
compensation paid by UBS to its directors and officers as a group in 1999 was
approximately CHF 193.1 million, including bonus compensation and approximately
CHF 2.7 million in accrued pension benefits. For the purposes of this analysis,
UBS's executive officers are the members of the UBS Group Managing Board, as
described above under "-- Control of Registrant."

OPTIONS TO PURCHASE SECURITIES FROM UBS

UBS offers employees options on UBS ordinary shares under five plans, as
described below:

Under the UBS Employee Ownership Plan and Senior Management Compensation
Program, key personnel are awarded that portion of their performance-related
compensation in excess of a predetermined amount in UBS ordinary shares,
warrants or options, which are restricted for a specified number of years.

Under the UBS Employee Investment Plan, employees have the option to invest part
or all of their annual bonus in UBS ordinary shares, warrants or other
derivatives on UBS ordinary shares. A certain holding period applies during
which the instruments cannot be sold or exercised.

Under the UBS Long Term Incentive and Key Award plans, long-term stock options
are granted to key employees. UBS considers the key employee's performance,
potential, years of service and the performance of the division in which the
employee works in determining the amount of the award. The options are blocked
for a certain period of time during which they cannot be exercised. For the 1997
options and certain of the 1998 options, one half of each grant is subject to an
acceleration clause after which certain forfeiture provisions lapse. One option
gives the right to purchase one registered share at the option's strike price.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

The following discussion and analysis should be read in conjunction with UBS's
consolidated financial statements and the related notes included elsewhere in
this document. UBS's consolidated financial statements have been prepared in
accordance with International Accounting Standards, or "IAS," which differ in
certain significant respects from U.S. GAAP. Please refer to Note 42 of UBS's
consolidated financial statements for a description of the significant
differences between IAS and U.S. GAAP and the reconciliation of shareholders'
equity and net profit (loss) to U.S. GAAP. Unless otherwise stated, all of UBS's
financial information presented in this document is presented on a consolidated
basis under IAS.

All references to 1999, 1998 and 1997 refer to UBS's fiscal years ended 31
December 1999, 1998 and 1997, respectively. The financial statements for each of
these periods have been audited by Ernst & Young Ltd., as described in the
"Report of Independent Auditors" on page F-1.

For comparative purposes, 1999 and 1998 figures have been restated to conform to
the 2000 presentation, which gives effect to certain accounting changes,
including:

- the removal from net trading income of profit on UBS ordinary shares held for
  trading purposes;

- the treatment of these shares as treasury shares, reducing both the number of
  shares and the shareholders' equity used in ratio calculations;

- the reclassification of trading-related interest revenues from net trading
  income to net interest income;

- the removal of the credit to net interest income and matching debit to net
  trading income for the cost of funding trading positions; and

- the capitalization of costs relating to the in-house development of software.

Note 1(t) of UBS's consolidated financial statements includes a complete
explanation of these accounting changes.

The 1998 merger of Swiss Bank Corporation and Union Bank of Switzerland, which
was completed on 29 June 1998, was accounted for under the
"pooling-of-interests" method of accounting. Under the pooling-of-interests
method, a single uniform set of accounting policies was adopted and applied
retrospectively for the restatement of comparative information. After the 1998
merger was effected, UBS began the process of integrating the operations of the
two banks. This process involved streamlining operations, eliminating duplicate
information technology infrastructure, consolidating banking premises and
various other measures to bring the two banks together. At the time of the 1998
merger, UBS established a restructuring provision of CHF 7 billion to cover its
expected restructuring costs associated with the 1998 merger. An additional
pre-tax restructuring charge of CHF 300 million

                                                                              51
<PAGE>   84
UBS
--------------------------------------------------------------------------------

in respect of the 1998 merger, representing about 4% of the original CHF 7
billion provision, was recognized in December 1999. The majority of the extra
provision was due to revised estimates of the cost of lease breaks and property
disposals. UBS has now largely completed the integration and restructuring
process relating to the 1998 merger and, at 30 June 2000, has used approximately
CHF 6.1 billion of the CHF 7.3 billion restructuring provision.

In addition, during the last three and a half years, a number of other events
occurred that also had a significant effect on UBS's results of operations
during these periods. These events included:

-  During 1999, UBS recognized pre-tax gains of CHF 1,490 million on the sale of
   its 25% stake in Swiss Life/Rentenanstalt; CHF 110 million on Julius Baer
   registered shares; CHF 200 million on the sale of its international Global
   Trade Finance business; and CHF 38 million on Long Term Capital Management,
   L.P.

-  During the first half of 1998, UBS divested Banca della Svizzera Italiana, or
   "BSI," and Adler & Co. Ltd. to satisfy a condition of the Swiss Competition
   Commission in connection with the 1998 merger. UBS recognized pre-tax gains
   of CHF 1,058 million on these sales.

-  During 1998, due to extremely volatile market conditions, UBS incurred losses
   of CHF 1,160 million relating to the write-down of its trading and investment
   positions in Long Term Capital Management, L.P. and CHF 762 million relating
   to its Global Equity Derivatives portfolio.

-  As of 31 December 1998, UBS established a provision of CHF 842 million in
   connection with the claims relating to the matter known as the Holocaust
   affair. UBS recognized additional pre-tax provisions of CHF 154 million
   relating to this claim in 1999 and CHF 200 million in 2000.

-  In the fourth quarter of 1999, UBS recognized a one-time credit of CHF 456
   million in connection with excess pension fund employer prepayments, recorded
   in accordance with IAS.

As a global financial services firm, UBS's businesses are affected by the
external environment in the markets in which it operates. In particular, the
results of UBS's business in Switzerland, and notably the results of its
credit-related activities, would be adversely affected by any deterioration in
the state of the Swiss economy because of the impact this would have on UBS's
customers' creditworthiness. More generally, economic and political conditions
in different countries can also impact UBS's results of operations and financial
position by affecting the demand for UBS's products and services and the credit
quality of UBS's borrowers and counterparties. Similarly, any prolonged weakness
in international securities markets would affect UBS's business revenues through
its effect on UBS's clients' investment decisions and the value of portfolios
under management, which would in turn reduce UBS's revenues from its private
banking and asset management businesses.

Competitive Forces.  UBS faces intense competition in all aspects of its
business. UBS competes with asset management entities, retail and commercial
banks, investment banking firms, merchant banks, broker-dealers and other
investment services firms. In addition, the trend toward consolidation in the
global financial services industry is enhancing the competitive position of some
of UBS's competitors by broadening the range of their product and service
offerings and increasing their access to capital. These competitive pressures
could result in increased pricing pressure on a number of UBS's products and
services, particularly as competitors seek to win market share.

Fluctuations in Currency Exchange Rates and Interest Rates.  Because UBS
prepares its accounts in Swiss francs, changes in currency exchange rates,
particularly between the Swiss franc and the U.S. dollar and the Swiss franc and
the British pound, may have an effect on the earnings that it reports. UBS's
approach to managing the risk is explained below under "--Asset and Liability
Management--Currency Management." In addition, changes in exchange rates can
affect UBS's business

--------------------------------------------------------------------------------
 52
<PAGE>   85
UBS
--------------------------------------------------------------------------------

earnings. For example, the establishment of the euro during 1999 has started to
have an effect on the foreign exchange markets in Europe by reducing the extent
of foreign exchange dealings among member countries and generating more
harmonized financial products. Movements in interest rates can also affect UBS's
results. As interest rates decline, UBS's interest rate margins generally come
under pressure and mortgage borrowers may seek to repay their borrowings early,
which can affect UBS's net interest income. Interest rate movements can also
affect UBS's fixed income trading portfolio and the investment performance of
its asset management businesses.

Operational Risks.  UBS's businesses are dependent on its ability to process a
large number of complex transactions across numerous and diverse markets in
different currencies and subject to many different legal and regulatory regimes.
UBS's systems and processes are designed to ensure that the risks associated
with UBS's activities are appropriately controlled, but UBS recognizes that any
weaknesses in these systems could have a negative impact on its results of
operations during the affected period.

As a result of these and other factors beyond its control, UBS's revenues and
operating profit have been and are likely to continue to be subject to a measure
of variability from period to period. Therefore UBS's revenues and operating
profit for any particular fiscal period may not be indicative of sustainable
results, may vary from year to year and may impact UBS's ability to achieve its
strategic objectives. Nevertheless, UBS's risk management and control procedures
have been designed to keep the risk of such variability at an acceptably low
level. For further discussion of UBS's risk management and control see
"--Analysis of Risks--Consequential Risks."

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Net interest
income increased by CHF 1,573 million, or 57.1%, from CHF 2,753 million in the
first half of 1999 to CHF 4,326 million in the first half of 2000. This was
principally the result of higher coupon income, in line with an increase of
interest bearing instruments in the trading portfolio.

As a result of the significant recovery of the Swiss economy in the first half
of 2000 and especially its effect on the real estate and real estate
construction markets, UBS was able to write back CHF 237 million of domestic
credit loss provisions in the first half of 2000. These writebacks were offset
by additional provisions on the international portfolio of CHF 154 million,
leading to a net credit of CHF 83 million in the credit loss expense line for
the first half of 2000, compared to an expense of CHF 635 million in the first
half of 1999.

(1)  Certain amounts have been restated to conform to the 2000 presentation.

Credit-related fees and commissions decreased in the first half of 2000 as a
result of the sale of UBS's International Global Trade Finance business in the
second half of 1999. Underwriting and corporate finance fees increased by 29%
over the first half of 1999 with strong results in both equity and fixed income
underwriting, and continuing increases in corporate finance revenues. Brokerage
fees were 58.3% higher in the first half of 2000 than in the first half of 1999
as a result of high levels of client activity in the context of strong market
volumes. The increase in investment fund fees from the first half of 1999 to the
first half of 2000 resulted from higher volumes and the inclusion in the first
half of 2000 of GAM, which was acquired in the fourth quarter of 1999. Portfolio
and other management and advisory fees increased CHF 437 million due to higher
asset-related fees in the first half of 2000.

Net trading income increased CHF 1,209 million, or 27.1%, to CHF 5,669 million
for the first half of 2000, compared to CHF 4,460 million for the first half of
1999, driven by strong growth in equity trading income and through increased
client activity, particularly in the first quarter of 2000. The

(1)  Certain amounts have been restated to conform to the 2000 presentation.

(2)  Includes other trading income such as banknotes, precious metals and
     commodities.

Net trading income from foreign exchange decreased CHF 38 million, or 5.3%, from
the first half of 1999 to the first half of 2000 in difficult trading
conditions, with lower levels of market activity and narrowing margins on
derivative products.

Net trading income from fixed income decreased CHF 660 million, or 50.7%, from
the first half of 1999 to CHF 643 million in the first half of 2000. The fixed
income component of net trading income does not represent the full revenue
picture of the Fixed Income business area within the Corporate and Institutional
Clients business unit. In particular, coupon income is managed as an integral
part of the trading portfolio. The relative revenue contributions of
mark-to-market gains, coupon income and other factors are somewhat volatile,
because they depend on trading strategies and the instrument composition. In the
first half of 2000, while fixed income trading income fell, coupon income, which
is reported in net interest income, rose substantially. The sum of the two
results suggests significantly more stable revenue development than either
component standing alone. In total, in the first half of 2000, revenues in the
Fixed Income business area of Corporate and Institutional Clients rose 13.6%
over the first half of 1999.

Net trading income from equities increased CHF 1,907 million, or 78.2%, from the
first half of 1999 to the first half of 2000. Positive markets led to an
exceptionally good first quarter of 2000, with record client volumes and strong
performances in European, U.S., U.K. and Japanese equities. Performance in the
second quarter fell slightly in more mixed market conditions, but was still well
ahead of second quarter of 1999.

Other income, including income from disposal of associates and subsidiaries,
decreased CHF 1,696 million, or 72.5%, from CHF 2,340 million in the first half
of 1999 to CHF 644 million in the first half of 2000. Total disposal-related
pre-tax gains were CHF 1,778 million in the first half of 1999 compared to CHF
23 million in the first half of 2000. The first half of 1999 included pre-tax
gains of CHF 1,490 million from the sale of UBS's stake in Swiss
Life/Rentenanstalt, CHF 200 million from the disposal of the Global Trade
Finance business and CHF 110 million from the sale of Julius Baer registered
shares. Excluding income from disposal of associates and subsidiaries, other
income increased CHF 59 million due to increased income from the disposal of
private equity investments and the consolidation of Klinik Hirslanden AG's
results in the first half of 2000 but not in the first half of 1999, offset by a
reduction of income from investments in associates and losses from the
revaluation of properties held for resale.

Personnel expense increased CHF 2,057 million, or 30.2%, from CHF 6,819 million
in the first half of 1999 to CHF 8,876 million in the first half of 2000,
despite an almost unchanged headcount of

47,744 at 30 June 2000, compared to 48,066 at 30 June 1999. This is primarily
attributable to higher performance-related compensation based on the very strong
results in the first half of 2000. In addition, CHF 567 million of the increase
is the result of adverse currency movements and CHF 182 million is due to the
consolidation of Klinik Hirslanden AG's results in the first half of 2000 but
not in the first half of 1999 and the inclusion of GAM, acquired in the fourth
quarter of 1999.

General and administrative expenses increased CHF 786 million, or 32.9%, from
CHF 2,388 million in the first half of 1999 to CHF 3,174 million in the first
half of 2000. General and administrative expenses in the first half of 2000
includes a final provision of CHF 200 million related to the U.S. global
settlement of Holocaust-related claims and CHF 110 million from the
consolidation of Klinik Hirslanden AG and the inclusion of GAM. Marketing and
public relations costs increased by CHF 102 million in the first half of 2000,
mainly due to the corporate re-branding program. CHF 146 million of the increase
primarily relates to information technology outsourcing charges for work that
was previously carried out in-house.

Depreciation and amortization increased CHF 83 million, or 9.6%, from CHF 864
million in the first half of 1999 to CHF 947 million in the first half of 2000,
mainly as a result of the acquisition of GAM and Allegis in the fourth quarter
of 1999.

Tax expense increased CHF 106 million, or 9.2%, from CHF 1,151 million in the
first half of 1999 to CHF 1,257 million in the first half of 2000, principally
due to increased operating profit. The effective tax rate of 22.6% in the first
half of 2000 is very slightly lower than the 22.9% rate in the first half of
1999.

Year to 31 December 1999 Compared to Year to 31 December 1998.  Net interest
income increased by CHF 891 million, or 17.8%, from CHF 5,018 million in 1998 to
CHF 5,909 million in 1999. Increased trading-related interest income and higher
interest margins in the domestic loan portfolio in 1999 from more consistent
application of UBS's risk-adjusted pricing model were partially offset by the
sale of business activities which had contributed to net interest income in
1998, as well as the impact of lower returns on invested equity and the
reduction of the international loan portfolio.

Credit loss expense had a slight increase of CHF 5 million from CHF 951 million
in 1998 to CHF 956 million in 1999. During 1999, UBS experienced general
improvements in the economy and in the credit performance of its loan portfolio,
and a reduction in impaired loans in the aggregate. Although impaired loans
decreased, additional provisions were required for some of the impaired domestic
loans remaining in the portfolio.

Net fee and commission income decreased by CHF 19 million from CHF 12,626
million in 1998 to CHF 12,607 million in 1999. Excluding the effect of
divestments in 1998, the decrease was roughly 1%.

Credit-related fees and commissions decreased in line with reduced emerging
market exposures and the sale of UBS's international Global Trade Finance
operations. As a result of strong results in mergers and acquisitions in 1999,
underwriting and corporate finance fees increased 8% relative to exceptionally
strong performance in 1998. Brokerage fees were higher in 1999 than in 1998
mainly due to strong volumes in the U.K., U.S. and Asia. A CHF 137 million
increase in investment fund fees was attributable to higher volumes and pricing
adjustments from the integration of the two pre-1998 merger product platforms.
Strong increases in custodian fees reflected higher custodian assets and a new
pricing model.

Net trading income increased CHF 4,406 million, or 133%, from CHF 3,313 million
in 1998 to CHF 7,719 million in 1999. The following table sets forth UBS's net
trading income by major business area for each of the years ended 31 December

Net trading income from foreign exchange decreased CHF 884 million, or 44.4%,
from 1998 to 1999 mostly as a result of lower volumes in key markets. The
reduced levels of activity resulted from the introduction of the euro and
narrowing margins from increased competition in global markets.

Net trading income from fixed income increased CHF 2,441 million from 1998 to
1999. During 1998, net trading income from fixed income was negatively impacted
by the pre-tax approximately CHF 790 million write-down of UBS's trading
position in Long Term Capital Management, L.P., or "LTCM,"

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

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

and approximately CHF 690 million in losses in UBS's emerging markets trading
portfolios. Excluding those write downs from the 1998 results, net trading
income from fixed income increased approximately 58% in 1999 over 1998. Fixed
income trading revenues were strong across all major products during 1999, led
by swaps and options and investment grade debt.

Net trading income from equities increased CHF 2,849 million from 1998 to 1999.
During 1998, net trading income was negatively impacted by pre-tax CHF 762
million in losses from the Global Equities Derivatives positions. In 1999, net
trading income benefited from very strong customer volumes in equity products
globally.

Other income, including income from disposal of associates and subsidiaries,
increased CHF 905 million, or 40.4%, from CHF 2,241 million in 1998 to CHF 3,146
million in 1999. Total disposal-related pre-tax gains were CHF 1,821 million in
1999 compared to disposal-related pre-tax gains of CHF 1,119 million in 1998.
The first-time consolidation of Klinik Hirslanden in 1999 resulting in other
income of CHF 395 million was partially offset by less income from investments
in associates as a result of the divestments as well as lower income from other
properties. The approximately CHF 370 million portion of the LTCM write-down
negatively impacted other income in 1998.

Personnel expense increased CHF 2,761 million, or 28.1%, from CHF 9,816 million
in 1998 to CHF 12,577 million in 1999, despite only a minor increase in
headcount from 48,011 at 31 December 1998 to 49,058 at 31 December 1999. At the
end of 1997, UBS foresaw the probability of a shortfall in profit in its
investment banking business as a result of the then-pending 1998 merger. In
order to protect its investment banking franchise, UBS realized it would
probably need to make payments to personnel in excess of amounts determined by
normal compensation methodologies. An amount of approximately CHF 1 billion was
recorded as part of the merger-related restructuring reserve for this purpose.
By the end of 1998, this shortfall had materialized, and CHF 1,007 million of
accrued payments to personnel were charged against the restructuring reserve in
1998 as planned. The shortfall in profits noted above was aggravated by losses
associated with LTCM and the Global Equity Derivatives, or "GED," portfolio.
Adjusting the prior year for the CHF 1,007 million, personnel expenses in 1999
increased by 16%, which was primarily attributable to higher performance-related
compensation based on the good investment banking result in 1999. Personnel
expense in 1999 was reduced by the recognition of CHF 456 million in pre-paid
employer pension contributions.

General and administrative expenses decreased CHF 637 million, or 9.5%, from CHF
6,735 million in 1998 to CHF 6,098 million in 1999. General and administrative
expenses in 1998 includes the provision of CHF 842 million for the settlement
related to the Holocaust litigation. In 1999, the following were included:

     - the additional restructuring provision of CHF 300 million;

     - an additional provision of CHF 154 million for the U.S. global settlement
       of Holocaust-related claims; and

     - CHF 130 million from the first-time consolidation of Klinik Hirslanden.

Excluding the impact of these items in 1998 and 1999, general and administrative
expenses decreased 6.4% year-on-year reflecting stringent cost reduction
programs.

Depreciation and amortization increased CHF 32 million, or 1.8%, from CHF 1,825
million 1998 to CHF 1,857 million in 1999. Excluding the impact of the
first-time consolidation of Klinik Hirslanden in 1999, depreciation and
amortization remained flat.

Tax expense increased CHF 782 million, or 86.5%, from CHF 904 million in 1998 to
CHF 1,686 million in 1999, principally due to increased operating profit. The
effective tax rate of 21.4% is lower than 23.4%, the rate in 1998, primarily due
to the utilization of tax loss carry forwards.

Year Ended 31 December 1998 Compared to Year Ended 31 December 1997.  The
following figures have not been restated for the changes in accounting policy
and restructuring of the UBS business groups that have been introduced during
2000, as such a restatement of the 1997 data was not practicable. As a result of
the differences in the reporting by the predecessor banks' accounting and
reporting policies, the unavailability of certain data, and the shut down and
modification of significant computer systems as a result of the 1998 merger and
to address Year 2000 issues, there is insufficient information to permit UBS to
restate the 1997 results for the changes in accounting policy.

</TABLE>

Net interest income decreased CHF 274 million, or 4.0%, from CHF 6,936 million
in 1997 to CHF 6,662 million in 1998. The decrease primarily resulted from lower
variable-rate mortgage volumes and the elimination of operations in 1998 that
generated interest income during 1997. Lower variable rate mortgage volumes
during 1998 more than offset an increase in fixed-rate mortgages. In addition,
although lower savings and deposit accounts reduced interest expense in 1998, it
also resulted in lower interest income from deposits during the year.

UBS's credit loss expense decreased CHF 327 million, or 25.6%, from CHF 1,278
million in 1997 to CHF 951 million in 1998. Credit loss expense improved because
of positive developments in the overall Swiss economy. This was offset in part
by the rapid deterioration of emerging market economies, most notably in Latin
America and Southeast Asia. This caused an approximately CHF 275 million net
increase in country provisions from 1997 to 1998 and other increases in
individual

counterparty allowances. The largest provisions in the emerging markets
economies were as follows at 31 December 1998 and 1997.

Net fee and commission income increased CHF 392 million, or 3.2%, from CHF
12,234 million in 1997 to CHF 12,626 million in 1998. Increases in underwriting
and corporate finance fees, custodian fees, portfolio and other management and
advisory fees, and fees from investment funds resulting from strong markets,
growth in assets under management and the acquisition of Dillon Read & Co., Inc.
in late 1997 all contributed to this net increase. These increases were
partially offset by a decrease in credit-related fees and commissions and
brokerage fees.

Net trading income decreased CHF 3,741 million, or 68.1%, from CHF 5,491 million
in 1997 to CHF 1,750 million in 1998. The decrease primarily resulted from the
CHF 790 million write-down of UBS's trading position in LTCM, the CHF 762
million loss on UBS's Global Equities Derivatives portfolio and approximately
CHF 810 million of losses on UBS's emerging markets trading portfolios. Net
trading income from foreign exchange and bank notes decreased by CHF 541 million
primarily reflecting losses in foreign exchange trading that were partially
offset by unusually strong results in UBS's cash and collateral trading
business. In addition, net trading income from precious metals and commodities
decreased by CHF 216 million, or 89%, from CHF 244 million in 1997 to CHF 28
million in 1998 due primarily to the wind-down of some of these businesses and
difficult trading conditions.

Other income, including income from disposal of associates and subsidiaries,
increased CHF 744 million, or 49.7%, from CHF 1,497 million in 1997 to CHF 2,241
million in 1998. The increase primarily reflected CHF 1,058 million gains on the
sales of BSI and Adler and gains in UBS's real estate and private equity
activities, partially offset by the CHF 370 million write-down of UBS's
investment in LTCM attributable to other income.

Personnel expense decreased CHF 1,743 million, or 15.1%, from CHF 11,559 million
in 1997 to CHF 9,816 million in 1998, reflecting reduced headcount of 13.0% from
55,176 people as of 31 December 1997 to 48,011 people as of 31 December 1998.
The headcount reduction primarily resulted from efficiencies gained from the
1998 merger and divestments of specific businesses. As discussed above, CHF
1,007 million of accrued payments to personnel were charged against the
restructuring reserve in 1998. Adjusting 1998 for this amount, personnel
expenses decreased 6.4% in 1998 compared to 1997.

General and administrative expenses increased CHF 1,302 million, or 24.5%, from
CHF 5,315 million in 1997 to CHF 6,617 million in 1998. This increase primarily
resulted from a CHF 842 million charge taken in 1998 for the settlement of the
claim relating to the Holocaust litigation and approximately CHF 397 million in
expenses recorded in 1998 associated with preparing for implementation of the
euro and for Year 2000 readiness.

Depreciation and amortization increased CHF 63 million, or 3.6%, from CHF 1,762
million in 1997 to CHF 1,825 million in 1998. Increased amortization of goodwill
and other intangible assets primarily resulting from additional goodwill
recorded in 1998 on Brinson Partners, the acquisition of Dillon Read & Co., Inc.
in September 1997 and the accelerated amortization of goodwill on Russian and
Brazilian subsidiaries due to the worsening markets in these countries in 1998
were the primary reasons for the increase from 1997 to 1998. These increases
were offset by a decrease in depreciation from the disposal of property and
equipment.

Tax expense increased CHF 1,150 million, from a tax benefit in 1997 of CHF 105
million to a tax expense in 1998 of CHF 1,045 million. In 1997, UBS recognized a
total current and deferred tax benefit of approximately CHF 1,600 million
related to the CHF 7,000 million restructuring provision. Excluding the
restructuring reserve, operating profit before tax would have been CHF 6,244
million in 1997 and UBS would have accrued tax expenses of CHF 1,395 million.

Operational Reserves.  UBS maintains operational reserves to provide for losses
associated with existing transaction errors in processing and other operational
losses. The reserves cover probable losses that exist in the portfolio as of the
balance sheet date, and are subject to senior management review and approval
within the specific business unit, functional operations and financial control
management and at the Group Executive Board.

UBS experienced an overall increase in the level of these reserves during 1999,
primarily related to UBS's continuing program of integrating the two predecessor
banks' domestic operations. As planned, this integration is taking longer than
the integration of operations outside Switzerland. There has been no significant
change in the level of these reserves in the first half of 2000.

Restructuring Provision.  At the announcement of the 1998 merger in 1997, UBS
estimated the costs it believed would result from integrating and restructuring
the operations of the two pre-existing banks and recorded a charge of CHF 7
billion. The charge included estimates for personnel-related costs, costs for
the elimination of duplicate infrastructures and the merging of bank premises,
and other 1998 merger-related restructuring costs. An additional pre-tax
restructuring charge of CHF 300 million in respect of the 1998 merger,
representing about 4% of the original CHF 7 billion provision, was recognized in
December 1999. The majority of the extra charge was taken to provide for revised
estimates of the cost of lease breaks and property disposals. UBS has now
largely completed the integration and restructuring process and, at 30 June
2000, has used approximately CHF 6.1 billion of the CHF 7.3 billion
restructuring provision.

During 1998, CHF 4,027 million of the restructuring provision was utilized
including:

     - CHF 2 billion for personnel-related expenses,

     - CHF 797 million for information technology integration projects and
       write-offs of equipment that management had committed to dispose of,

     - CHF 267 million for merging premises, and

     - CHF 939 million for costs associated with the exit of specific
       businesses, as well as merger administration costs.

Included in the CHF 2 billion of personnel-related expenses are severance
payments and payments required to maintain stability in the workforce during the
1998 merger-related integration period, as well as some performance-related
compensation as discussed above.

During 1999, CHF 1,844 million of the restructuring provision was utilized,
bringing the total utilization to CHF 5,871 million at 31 December 1999. The
transition to one common technology platform and parallel operation of the
systems in UBS Switzerland's Private and Corporate Clients business unit and the
merger of bank premises, including related moving, outfitting and vacancy costs,
recognized in Corporate Center, were the primary uses of the provision in 1999.

During the first half of 2000, the main use of the restructuring provision
related to premises costs in Corporate Center, including moving, outfitting and
vacancy costs that were charged against the provision, and also to costs
relating to the early retirement plan in Private and Corporate Clients. The
following table analyzes the use of the restructuring provision through the
first half of 2000.

The substantial majority of the remaining restructuring reserve balance is also
attributed to employees and real estate located in Switzerland. UBS estimates
that the balance of the reserve will be used in the second half of 2000 and in
2001.

UBS has achieved 1998 merger-related cost savings of CHF 2 billion per year,
including savings related to headcount reductions of CHF 1.6 billion and savings
for other costs estimated to be around CHF 0.4 billion per year, including
approximately CHF 75 million in eliminated depreciation expenses and other costs
related to real estate.

Since the 1998 merger was announced, UBS Warburg has essentially completed its
integration including the reduction of personnel and the integration of
information technology platforms. As expected, most of the cost savings over the
past two years have been attributable to UBS Warburg.

UBS Asset Management has also essentially completed its integration, while in
the Corporate Center UBS expects the write-off or sale of the remaining
redundant real estate to proceed in 2000 and 2001.

Within UBS Switzerland, Private Banking's integration is essentially complete.
Private and Corporate Clients, meanwhile, has been rapidly integrating its
business in line with a detailed timetable and project schedule. For example,
the branch network has been reduced by 36%, or 200 branches. In addition, now
that the integration of the technology platforms has been completed and in line
with employee association agreements made in 1998, redundancy plans will gain
momentum during 2000 and 2001.

As with any merger, cost savings attributable directly to the 1998 merger are
becoming increasingly difficult to track. Across all divisions, normal organic
business growth, new investments and initiatives, and at least three
acquisitions and six divestitures have clouded underlying developments since the
time of the 1998 merger.

For example, UBS Warburg's Private Clients business unit has invested heavily
over the past two years in building up its onshore private banking business
outside Switzerland. Additionally, in 1999, UBS formed the e-services business
area, which will experience further significant investment. More information on
various divisional initiatives can be found in the respective business
descriptions.

UBS is also implementing general cost control initiatives across all divisions,
which extend well beyond merger-related savings. These initiatives are already
well-structured at UBS Warburg's Corporate and Institutional Clients business
unit and UBS Switzerland's Private and Corporate Clients business unit.
Corporate and Institutional Clients is continuing to focus on cost management
with emphasis on improving overall efficiency such that revenue growth exceeds
any growth in non-personnel costs.

In addition, the Corporate and Institutional Clients Investment Committee has
carried out a rigorous review process to ensure that investments in the business
unit's infrastructure are fully aligned with the strategy of the business.

Within the UBS Switzerland Private and Corporate Clients business unit, the
Strategic Projects Portfolio is expected to enhance revenues and reduce costs,
including the ongoing realization of the remaining merger-related cost savings.
This portfolio is well on track and is expected to yield a significant
improvement in net profit by 2002.

In the third quarter of 1998, UBS realized a post-tax loss of CHF 984 million as
a result of a write-down of its investment in Long Term Capital Management,
L.P., or LTCM, and a post-tax loss of CHF 919 million as a result of unrealized
losses in the value of its Global Equity Derivatives, or GED, portfolio.

Long Term Capital Management.  In the case of LTCM, the loss arose from a
structured transaction in which UBS sold an option that gave the optionholder
the right to purchase shares in LTCM at a predetermined price over a seven-year
period. In order to hedge the risk of this option, UBS held $800 million of LTCM
shares to create an incrementally risk neutral position. Separate from the
structured transaction, UBS also made a further direct equity investment of $266
million in LTCM. In normal market conditions, the structured transaction would
have behaved in a controlled manner. However, the structured transaction could
not be effectively hedged, particularly in the event of extreme market
movements. As a result of the structured transaction, UBS was exposed to a
sudden and severe downward movement in the value of LTCM equity, and had very
limited scope to hedge this exposure. LTCM's equity was not traded and was
valued only periodically based on the underlying instruments held by LTCM.
Moreover, LTCM did not provide detailed information about its investment
results. Consequently, UBS could not hedge with any precision against adverse
moves in the value of LTCM's equity. In particular, when LTCM was faced by a
sharp adverse move in market prices relating to certain specific investment
strategies, UBS was unable to hedge this risk itself as it had no knowledge of
the details of these strategies.

At the time of the recapitalization of LTCM in 1998, UBS wrote down its initial
investment in LTCM and also agreed to provide a further $300 million (out of
$3.6 billion provided by a group of financial institutions) of "consortium"
equity in order to avoid a forced liquidation of LTCM and to enable LTCM's
portfolio to be managed under the oversight of a management board that would
oversee the orderly winding down of LTCM's portfolio.

On 24 November 1999, at the release of its nine month 1999 results, UBS reported
that its initial investment, which was written down to $106 million, had been
bought back by LTCM, with an immaterial impact on UBS's income statement. That
position is now closed. In addition, as part of UBS's "consortium" investment,
four cash payments totaling $296 million were received by UBS by 31 December
1999. Of these cash repayments, $271 million were treated as a return of its

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

UBS
--------------------------------------------------------------------------------

$300 million investment, to leave a remaining balance of $29 million, and $25
million was recorded as income.

Global Equity Derivatives (GED) Portfolio.  The other major contributory factor
to the third-quarter 1998 losses related to the GED portfolio. This portfolio
consists of a number of structured equity derivative transactions. This
portfolio was analyzed at the time of the merger and it was recognized that it
contained a number of positions that possessed the potential for significant
short-term variance. Consequently, when equity market volatilities increased
significantly as a result of the market turmoil in the third quarter of 1998, an
unrealized loss of about CHF 728 million on the value of the portfolio arose.
Over the next 12 months, as volatilities fell and positions were reduced, income
from the portfolio of approximately CHF 306 million was recognized.

UBS continues to manage the exposure associated with this portfolio in order to
minimize the risk of further adverse effects on earnings. The positions have now
been included in UBS's standard equity risk management platform and are subject
to its normal risk control and stress loss processes. UBS has been reducing the
market risk associated with the portfolio and will continue to do so through
specific hedges, close-outs and the passage of time. These positions, including
the associated hedges, are all carried at fair value. However, given that the
average maturity of the transactions in the portfolio is about two years, it
will take some time to wind down this exposure, and during this time the
portfolio will continue to be exposed to adverse moves in equity markets.

Reconciliation of IAS to U.S. GAAP.  UBS's consolidated results of operations
are prepared in accordance with IAS, which differs in certain respects from U.S.
GAAP. A reconciliation of the effects on shareholders' equity and net
profit/(loss) to U.S. GAAP for the years ended 31 December 1999 and 1998 is
included in Note 42 of UBS's consolidated financial statements.

Results of Operations by Business Unit

UBS's management reporting system and policies were used to determine the
revenues and expenses directly attributable to each business unit. Internal
charges and transfer pricing adjustments have been reflected in the performance
of each business unit. The basis of the reporting reflects UBS's current
management structure (UBS Warburg, UBS Asset Management, UBS Switzerland and
Corporate Center), rather than the management structure that existed during 1999
and during 1998, following the 1998 merger (UBS Asset Management, UBS Private
Banking, UBS Capital, UBS Private and Corporate Clients, UBS Warburg and
Corporate Center).

Inter-business unit revenues and expenses include transfers between business
units and between geographical locations. Inter-business unit expense charges
are recorded as a reduction to expenses in the business unit providing the
service. Corporate Center expenses are allocated to the operating business
units, to the extent possible, whereby the business unit controlling the process
that is driving the expense bears the expense.

The credit loss expense included in the business unit results is a statistically
derived adjusted annual expected loan loss that reflects the inherent
counterparty and country risks in the respective portfolios. The expected loss
is based on assumptions about developments covering a full economic cycle and on
cumulative loss probabilities over the entire life of the loan portfolio. In
determining the inherent counterparty and country risk in the portfolio, UBS
takes into consideration the statistical probability of default by the customer
and the severity of loss.

As each business unit is ultimately responsible for its credit decisions, the
difference between actual credit losses and annual expected loan loss will
eventually be charged or credited back to the business unit in order to ensure
that the risks and rewards of credit decisions are fully reflected in its
results. The difference between the statistically adjusted expected loss that is
charged to the management

Business unit results are presented according to the current management
structure and current accounting treatment for the following periods:

- Six months ended 30 June 2000 compared to six months ended 30 June 1999; and

- Year ended 31 December 1999 compared to year ended 31 December 1998.

Results for the year ended 31 December 1998 compared to the year ended 31
December 1997 are presented in terms of the business divisions through which UBS
was managed at that time, namely UBS Private Banking, UBS Private and Corporate
Clients, UBS Warburg, UBS Capital, UBS Asset Management and Corporate Center. As
a result of the differences in the reporting by the predecessor banks'
accounting and reporting policies, the unavailability of certain data, and the
shut down and modification of significant computer systems as a result of the
1998 merger and to address Year 2000 issues, there is insufficient information
to permit UBS to restate these results in terms of the current business group
and business unit structure.

The principal differences between the structure in 1997 and the current
structure are that the UBS Asset Management Investment Funds business unit and
the UBS Warburg Private Clients business unit were part of the Private Banking
Division, and their results are included within that Division. In addition, UBS
Warburg's UBS Capital business unit was an autonomous division, and UBS Warburg
itself consisted only of what is now the UBS Warburg Corporate and Institutional
Clients business unit.

In addition the comparison of the year ended 31 December 1998 with the year
ended 31 December 1997 is based on results which are presented without
restatement for new accounting policies introduced in 2000. The principal effect
of this is within UBS Warburg. For further details, see Note 1(t) to UBS's
consolidated financial statements.

In considering these results it is important to bear in mind the following
representations with regard to the factors that may affect the operating income
of each business unit.

INTRODUCTION.

UBS SWITZERLAND.

Private and Corporate Clients.  Private and Corporate Clients derives its
operating income principally from:

- interest income on its loan portfolio;

- fees for investment and asset management services;

--------------------------------------------------------------------------------
 66
<PAGE>   99
UBS
--------------------------------------------------------------------------------

- transaction fees; and

- investment income from deposits.

As a result, Private and Corporate Clients' operating income is affected by
movements in interest rates, fluctuations in assets under management, client
activity, investment performance and changes in market conditions.

Private Banking.  Private Banking derives its operating income from:

- fees for financial planning and wealth management services;

- fees for discretionary services; and

- transaction-related fees.

Private Banking's fees are based on the market value of assets under management
and the level of transaction-related activity. As a result, Private Banking's
operating income is affected by such factors as fluctuations in assets under
management, changes in market conditions, investment performance and inflows and
outflows of client funds.

UBS Asset Management.

Prior to the reorganization of UBS in February 2000, UBS Asset Management
generated most of its revenue from the asset management services it provides to
institutional clients. In 2000 this has become more evenly divided between
institutional and non-institutional sources due to the addition of GAM and the
Investment Funds business area. Fees charged to institutional clients and on
investment funds are based on the market value of assets under management. As a
result, UBS Asset Management's revenues are affected by changes in market
conditions as well as new and lost business.

UBS WARBURG.

Corporate and Institutional Clients.  Corporate and Institutional Clients
generates operating income from:

- commissions on agency transactions and spreads or markups on principal
  transactions,

- fees from debt and equity capital markets transactions, leverage finance and
  structuring derivatives and complex transactions;

- mergers and acquisitions advisory fees;

- interest income on principal transactions and from the loan portfolio; and

- gains and losses on market making, proprietary and arbitrage positions.

As a result, Corporate and Institutional Clients's operating income is affected
by movements in market conditions, interest rate swings, the level of trading
activity in primary and secondary markets and the extent of merger and
acquisition activity. These and other factors outside the control of Corporate
and Institutional Clients have had and may in the future have a significant
impact on its results of operations from year to year.

UBS Capital.  UBS Capital's primary source of operating income is capital gains
from the disposition or sale of its investments, which are recorded at the time
of ultimate divestment. As a result, appreciation in fair market value is
recognized as operating income only at the time of sale. The level of annual
operating income from UBS Capital is directly affected by the level of
investment dispositions that take place during the course of a year. With the
formation of regional funds, UBS Capital has begun to receive management fees
from funds UBS manages and sponsors, which are recorded as operating income.

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

Private Clients.  Private Clients derives its operating income from:

- fees for financial planning and wealth management services;

- fees for discretionary services; and

- transaction-related fees.

Private Clients' fees are based on the market value of assets under management
and the level of transaction-related activity. As a result, Private Clients'
operating income is affected by such factors as fluctuations in assets under
management, changes in market conditions, investment performance and inflows and
outflows of client funds.

e-services.  The e-services business unit has not yet generated revenues, but
expects to generate revenues from fees for financial planning and wealth
management services, fees for discretionary services and transaction related
fees. It is expected that these fees will be based on the market value of assets
under management and the level of transaction-related activity. As a result,
e-services' operating income will be affected by such factors as fluctuations in
assets under management, changes in market conditions, investment performance
and inflows and outflows of client funds. In addition, e-services is a new
business with no existing clients and an as yet unproven business model.
e-services' possible future income will be affected by its ability to attract
clients and by the success or failure of its business model.

UBS Switzerland.  The business group UBS Switzerland is made up of two business
units:

- Private and Corporate Clients, the leading retail and commercial bank in
  Switzerland; and

- Private Banking, which covers all Swiss and international high net worth
  clients who bank in Switzerland or offshore centers.

Private and Corporate Clients.  The following table sets forth the results of
Private and Corporate Clients for the half years ended 30 June 2000 and 30 June
1999 and the years ended 31 December 1999 and 1998.

(1) Income by business area is only reported at year end.

(2) Certain amounts have been restated to conform to the 2000 presentation.

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Operating
income before credit loss expense increased CHF 204 million, or 5.7%, from CHF
3,599 million in the first half of 1999 to CHF 3,803 million in the first half
of 2000. This improvement was primarily due to increased brokerage revenues in
the strong market conditions, particularly in the first quarter of 2000. Private
and Corporate Clients' results are dependent on interest-related businesses,
which contribute almost 60% of operating income.

Private and Corporate Clients' credit loss expense decreased CHF 142 million, or
26%, from CHF 554 million in the first half of 1999 to CHF 412 million in the
second half of 2000 as a result of improved asset quality and increased
collateral values.

Personnel, general and administrative expenses decreased CHF 70 million, or
3.1%, from CHF 2,224 million in the first half of 1999 to CHF 2,154 million in
the first half of 2000. This decrease was due primarily to continued reduction
in personnel expense, in line with headcount reductions as a result of the 1998
merger. General and administrative expenses increased by 1%, or CHF 6 million,
from CHF 501 million in the first half of 1999 to CHF 507 million in the first
half of 2000, while personnel expenses fell 4% or CHF 76 million to CHF 1,647
million in the first half of 2000.

Year to 31 December 1999 Compared to Year to 31 December 1998.  Operating income
before credit loss expense increased CHF 168 million, or 2.4%, from CHF 7,025
million in 1998 to CHF 7,193 million in 1999. This improvement was primarily due
to higher margins on interest-related business, such as mortgages, as well as
the first full-year impact of the amalgamation and repricing of products from
the two former banks. In conjunction with the creation of the Risk
Transformation and Capital Management business area in October 1999, the
business areas within Private and Corporate Clients were realigned in 1999.
These realignments and the resulting effects on 1999 operating income were as
follows:

- The Business Client segment was transferred from Individual Clients to
  Corporate Clients resulting in a decrease in operating income from Individual
  Clients from 1998 to 1999.

- Operating income from Corporate Clients increased from 1998 to 1999 primarily
  due to the transfer in of the Business Client segment, the transfer in of the
  Swiss Global Trade Finance business from UBS Warburg and improving interest
  margins. The transfer out of the Recovery portfolio to Risk Transformation and
  Capital Management partially offset these increases.

UBS
--------------------------------------------------------------------------------

- Operating income from Operations decreased compared to 1998. This was the net
  effect of the transfer of emerging market bank activities from UBS Warburg
  into UBS Private and Corporate Clients and the transfer of industrialized bank
  activities to UBS Warburg during 1999.

UBS's credit loss expense decreased CHF 120 million, or 10.3%, from CHF 1,170
million in 1998 to CHF 1,050 million in 1999 as a result of the accelerated
reduction of impaired positions and the movement to higher quality businesses.
This was partially offset by increased loss expectations primarily resulting
from the transfer of the remainder of the Swiss Global Trade Finance business
from UBS Warburg during 1999.

Personnel, general and administrative expenses increased CHF 223 million, or
5.2%, from CHF 4,263 million in 1998 to CHF 4,486 million in 1999. This increase
was due primarily to merger related IT integration work, work relating to the
Year 2000 transition and the costs associated with the shift of the Swiss Trade
Finance business from UBS Warburg. This business, with approximately 400
professionals, was transferred from UBS Warburg in early 1999. These increases
were partially offset by cost savings resulting from the closure of redundant
branches.

Depreciation and amortization expense decreased CHF 298 million, or 43.6%, from
CHF 684 million in 1998 to CHF 386 million in 1999, primarily due to reduced
assets employed subsequent to the merger.

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Operating
income before credit loss expense increased CHF 743 million, or 27.2%, from CHF
2,728 million in the first half of 1999 to CHF 3,471 million in the first half
of 2000. This increase principally reflected higher transaction-based revenues
due to higher levels of client transaction activity and asset growth since 30
June 1999.

UBS
--------------------------------------------------------------------------------

Assets under management increased CHF 53.0 billion, or 8.4%, from 30 June 1999
to 30 June 2000, with most of the increase due to positive performance trends,
partially offset by a net decline of CHF 3 billion in new money.

Operating expenses increased 24.8%, or CHF 295 million, to CHF 1,480 million
from the first half of 1999 to the first half of 2000, mainly due to increased
general and administrative expense.

Personnel, general and administrative expenses increased CHF 278 million, or
24.2%, from CHF 1,147 million in the first half of 1999 to CHF 1,425 million in
the first half of 2000. Personnel costs increased 16.5%, or CHF 109 million, to
CHF 769 million in the first half of 2000, due to increased performance-related
compensation in line with strong first half 2000 results and an increase in
headcount. Headcount went up by 750 from 6,697 at 30 June 1999 to 7,447 at 30
June 2000 as Private Banking expanded its front line staff and strengthened its
logistics. General and administrative expenses increased 34.7%, or CHF 169
million, from the first half of 1999 to the first half of 2000 due to increases
in IT and marketing expenses and higher intra-Group cost recoveries, driven by
higher transaction levels.

Goodwill amortization increased CHF 9 million, or 112.5%, to CHF 17 million in
the first half of 2000 as a result of the acquisition of Bank of America's
international private banking business, which took place in the second quarter
of 1999. Depreciation increased CHF 8 million, or 26.6%, from CHF 30 million in
the first half of 1999 to CHF 38 million in the first half of 2000.

Year to 31 December 1999 Compared to Year to 31 December 1998.  In March 1999,
UBS acquired Bank of America's international private banking operations in
Europe and Asia, thereby increasing the assets under management in UBS Private
Banking by approximately CHF 5 billion as of 31 December 1999. The remainder of
the increase was principally performance related.

Operating income before credit loss expense decreased CHF 1,365 million, or
19.7%, from CHF 6,933 million in 1998 to CHF 5,568 million in 1999. This
significant decrease principally reflected lower transaction-based revenues due
to lower levels of client transaction activity. CHF 1,058 million gains from the
divestitures of BSI and Adler, as well as CHF 268 million of operating income
relating to BSI's operations, are included in operating income for 1998 and did
not recur in 1999. Excluding the disposal related income, operating income from
UBS Private Banking increased 2.3% from 1998 to 1999.

Notwithstanding the decrease in operating income, assets under management
increased during 1999 by CHF 92 billion, or 15.9%. Strong markets, especially in
Europe, the United States and in the technology sector, as well as the stronger
U.S. dollar, led to a performance increase of CHF 80 billion for 1999. In
addition, the acquisition of the international private banking operations of
Bank of America accounted for an additional CHF 5 billion while interdivisional
transfers resulted in another CHF 6 billion. This increase was partially offset,
however, by decreased volumes from existing clients during the second half of
1999.

Operating expenses, adjusting for CHF 125 million in divestiture-related
operating expenses, increased 4.3%, or CHF 108 million, to CHF 2,610 million in
1999, to a large extent as a result of UBS's expansion in the front-line staff
as well as infrastructure related investments.

Personnel, general and administrative expenses increased CHF 102 million, or
4.2%, from CHF 2,411 million in 1998 to CHF 2,513 million in 1999. Personnel
costs increased 9.7%, or CHF 118 million, to CHF 1,328 million, in 1999 due to
an increase in headcount of 710 from 6,546 at 31 December 1998 to 7,256 at 31
December 1999. Headcount growth resulted from the acquisition in 1999 of Bank of
America's international private banking operations, enhancement of UBS's
logistics capabilities and support for the introduction of new portfolio
monitoring and advisory capabilities. Operating expenses in 1998 also included
CHF 125 million related to BSI that did not occur in 1999.

As a result of the acquisition of the international private banking operations
of Bank of America, goodwill amortization increased by CHF 21 million in 1999.
Depreciation decreased CHF 15 million, or 16.5%, from CHF 91 million in 1998 to
CHF 76 million in 1999.

(1) Certain amounts have been restated to conform to the 2000 presentation.

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Assets under
management decreased 6.7% or CHF 38 billion, from CHF 563 billion at 30 June
1999 to CHF 525 billion at 30 June 2000, with increases in non-institutional
assets under management more than offset by losses in institutional assets under
management. Non-institutional assets under management increased primarily
because of market performance, while institutional assets under management
declined mainly due to client losses, as a result of performance issues in
equity related mandates, offset by the effect of currency movements and the
acquisition of Allegis Realty Investors LLC in December 1999.

Operating income increased CHF 96 million, or 17.5%, from CHF 542 million in the
first half of 1999 to CHF 638 million in the first half of 2000. Despite the
decrease in assets under management, operating income increased as a result of
the acquisition of Allegis, the addition of the O'Connor alternative asset
management business formed in June 2000 and positive currency movements,
partially offset by lost revenue from client losses.

Personnel, general and administrative expenses increased CHF 71 million, or
21.5%, from CHF 331 million in the first half of 1999 to CHF 402 million in the
first half of 2000. Headcount increased 13.6% from 1,507 as of 30 June 1999 to
1,712 as of 30 June 2000, primarily as a result of the acquisition of Allegis in
December 1999 and the creation of the O'Connor business in June 2000. Personnel
expenses increased 18.7% from CHF 252 million in the first half of 1999 to CHF
299 million in the first half of 2000 due to the acquisition of Allegis, the
addition of the O'Connor business and currency movements. General and
administrative expenses increased 30.4% to CHF 103 million in the period as a
result of the acquisition of Allegis and currency movements.

Depreciation and amortization expense increased CHF 35 million, or 56%, from CHF
63 million in the first half of 1999 to CHF 98 million in the first half of
2000, reflecting the acquisition of Allegis.

Year to 31 December 1999 Compared to Year to 31 December 1998.  Operating income
decreased CHF 64 million, or 5.5%, from CHF 1,163 million in 1998 to CHF 1,099
million in 1999. Assets under management increased 8.1%, or CHF 43 billion, to
CHF 574 billion at 31 December 1999, with increases in both institutional and
non-institutional categories year-on-year. Despite the 4.4% increase in
institutional assets under management, which primarily resulted from investment
performance, the acquisition of Allegis and growth in private client mandates,
institutional revenues decreased. This decrease from CHF 968 million in 1998 to
CHF 903 million in 1999 reflects a slight decline in average institutional
assets under management from 1998 to 1999, as gains from performance and
currency were offset by loss of clients and performance issues in certain
mandate types. Non-institutional assets increased by 16% during 1999; however,
non-institutional revenues declined slightly to CHF 193 million as a result of
new interdivisional fee arrangements with UBS Private Banking.

Personnel, general and administrative expenses increased CHF 17 million, or
2.7%, from CHF 619 million in 1998 to CHF 636 million in 1999. Headcount
increased from 1,497 as of 31 December 1998 to 1,653 as of 31 December 1999,
primarily as a result of the acquisition of Allegis in December 1999. Personnel
expenses decreased slightly from CHF 465 million in 1998 to CHF 458 million in
1999 reflecting decreased incentive compensation. General and administrative
expenses increased 15.6% to CHF 178 million in 1999 as a result of revisions in
cost-sharing arrangements between Institutional Asset Management and other
divisions of UBS.

Depreciation and amortization expense increased CHF 31 million, or 29%, from CHF
107 million in 1998 to CHF 138 million in 1999, reflecting increased goodwill
amortization related to the buy-out of UBS's joint venture with the Long-Term
Credit Bank of Japan.

(1)  Certain amounts have been restated to conform to the 2000 presentation.

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Assets under
management increased 18.4%, or CHF 35 billion, from CHF 190 billion at 30 June
1999 to CHF 225 billion at 30 June 2000, as a result of the acquisition of GAM,
which had CHF 24 billion assets under management at 31 December 1999, and
positive market performance.

Operating income increased CHF 232 million, or 227.5%, from CHF 102 million in
the first half of 1999 to CHF 334 million in the first half of 2000. This was a
result of the GAM acquisition and increases in Investment Fund fees from higher
asset levels.

Personnel, general and administrative expenses increased CHF 140 million, or
187%, from CHF 75 million in the first half of 1999 to CHF 215 million in the
first half of 2000. Headcount increased 165% from 392 as of 30 June 1999 to
1,038 as of 30 June 2000, primarily as a result of the acquisition of GAM and an
increase of about 100 people to support increased marketing and distribution
initiatives in Investment Funds. Personnel expenses increased 321% from CHF 29
million in the first half of 1999 to CHF 122 million in the first half of 2000
due to the acquisition of GAM. General and administrative expenses increased
102.2% from 30 June 1999 to CHF 93 million at 30 June 2000 as a result of the
acquisition of GAM and marketing and distribution initiatives in Investment
Funds.

Depreciation and amortization expense increased CHF 52 million, or 1,733% from
CHF 3 million in the first half of 1999 to CHF 55 million in the first half of
2000, reflecting goodwill amortization following the acquisition of GAM.

Year to 31 December 1999 Compared to Year to 31 December 1998.  Operating income
increased CHF 75 million, or 38.5%, from CHF 195 million in 1998 to CHF 270
million in 1999. This was principally due to higher Investment Funds assets and
the transfer from Private Banking of some client responsibility and related
income. The acquisition of GAM did not impact income or expenses in 1999.

Assets under management increased 28.1%, or CHF 50 billion, to CHF 225 billion
at 31 December 1999. CHF 24 billion of this increase was due to the acquisition
of GAM in December 1999. The remainder was mainly due to positive investment
performance.

Personnel, general and administrative expenses increased CHF 27 million, or
21.7%, from CHF 124 million in 1998 to CHF 151 million in 1999. Headcount
increased from 366 as of 31 December 1998 to 923 as of 31 December 1999,
primarily as a result of the acquisition of GAM in December 1999. Excluding GAM,
headcount increased by 69, as a result of efforts to build the Investment Funds
business, including the launching of new funds and expansion of distribution
efforts. Personnel expenses increased 16% from CHF 50 million in 1998 to CHF 58
million in 1999 in line with the increase in headcount. General and
administrative expenses increased 25.7% to CHF 93 million in 1999 reflecting
increased investment in international distribution and the costs of launching
new funds, offset by synergies from the 1998 merger, including reduced fees for
market data systems and the combination of fund valuation and management
systems.

Depreciation and amortization expense increased CHF 1 million, or 16.7%, from
CHF 6 million in 1998 to CHF 7 million in 1999, as a result of changes in the
holding structure of some of the business unit's real estate funds.

Corporate and Institutional Clients.  The Corporate Finance business area within
Corporate and Institutional Clients provides both advisory services and
financing services. The financing services include both equity and fixed-income
offerings undertaken in cooperation with the Equity Capital Markets, Debt
Capital Markets and Leveraged Finance groups. Accordingly, a portion of
operating income associated with these equity and fixed-income financing
services is allocated to Corporate Finance and the remaining operating income is
allocated to the Equities business area or Fixed Income business area as
appropriate.

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Operating
income increased CHF 3,001 million, or 44.2% from CHF 6,795 million in the first
half of 1999 to CHF 9,796 million in the first half of 2000. Corporate Finance
revenues increased in the first half of 2000 with a strong performance in
mergers and acquisitions, and both Equities and Fixed Income produced record
revenues reflecting active markets and record levels of client commissions,
offset by slightly weaker performances by Treasury Products.

Credit loss expense decreased CHF 58 million, or 33.9%, from CHF 171 million in
the first half of 1999 to CHF 113 million in the first half of 2000. This
reflected a decrease in expected credit losses due primarily to the continued
wind-down of the non-core loan portfolio and the sale of the international
Global Trade Finance business in mid-1999.

Personnel, general and administrative expenses increased CHF 1,629 million, or
32.8%, from CHF 4,972 million in the first half of 1999 to CHF 6,601 million in
the first half of 2000. Despite a slight reduction in headcount of 418 from
13,148 at 30 June 1999 to 12,730 at 30 June 2000, personnel expenses increased
CHF 1,464 million, or 37.6%, to CHF 5,362 million in the first half of 2000, due
primarily to performance-related compensation tied directly to the strong
results for the half. General and administrative expenses increased by CHF 165
million, or 15.4%, from the first half of 1999 to the first half of 2000, mainly
driven by increased investments in e-commerce and technology.

Depreciation and amortization decreased CHF 63 million, or 16%, from CHF 393
million in the first half of 1999 to CHF 330 million in the first half of 2000,
as the depreciation impact of 1998 merger-related IT and premises projects
diminished.

UBS
--------------------------------------------------------------------------------

Year to 31 December 1999 Compared to Year to 31 December 1998.  In October and
November 1998, UBS's Board of Directors mandated and undertook a review of UBS's
risk profile and risk management as well as UBS's control processes and
procedures. The review placed particular emphasis on the Fixed Income business
area, which had experienced losses on credit exposures in certain emerging
market assets. Each of the business areas selected for review was assessed as to
whether it supported the UBS and UBS Warburg franchises and, if so, whether the
expected return as compared to the estimated risk justified a continuation of
the business. Corporate and Institutional Clients used the review to define its
core and non-core business areas, and decided to wind down over time the
identified non-core businesses.

The businesses identified as non-core in late 1998 were:

     -  Lease Finance;

     -  Commodities Trading (energy, base metals, electricity);

     -  Non-structured Asset-Backed Finance;

     -  Distressed Debt Trading;

     -  Global Trade Finance, with the exception of the Swiss corporate
        business;

     -  Conduit Finance;

     -  Non-core loans -- loans and commitments that are not part of UBS's
        tradeable asset portfolio, that are not issued in conjunction with UBS's
        Leveraged Finance business or that are credit exposures UBS wishes to
        reduce; and

     -  Project Finance.

The identified non-core businesses are being wound down over time and will be
disposed of as appropriate. While UBS considers all of its non-core businesses
to be held for sale (including those listed above), none of these businesses
constitutes a segment to be treated as a discontinued operation, as defined by
U.S. GAAP. Businesses designated as non-core businesses remain consolidated for
purposes of both IAS and U.S. GAAP unless and until such businesses are actually
sold or otherwise disposed of. Most of UBS's international Global Trade Finance
business was sold during the first quarter of 1999 and its Conduit Finance
business was sold during the third quarter of 1999. UBS's non-core loan
portfolio decreased approximately CHF 65 billion, or 61.3%, from approximately
CHF 106 billion as of 31 December 1998 to CHF 41 billion as of 31 December 1999.

Negotiations for the sale of the Project Finance portfolio and residual Global
Trade Finance positions were completed in December 1999 for proceeds
approximating their carrying values. As a result, no material losses were
realized. Certain aspects of UBS's Global Equities Derivatives portfolio
previously identified at the time of the 1998 merger as inconsistent with UBS's
risk profile were also designated as a non-core business during late 1998 in
order to segregate this activity from the rest of its Equities business. UBS
accrued CHF 154 million as a restructuring reserve for this portion of the
portfolio.

In 1999, Corporate and Institutional Clients' operating income before credit
loss expense from core businesses amounted to CHF 12,047 million and its
operating income before credit loss expense from non-core businesses was CHF 682
million.

Operating income from Equities increased CHF 2,471 million, or 76%, from CHF
3,253 million in 1998 to CHF 5,724 million in 1999. This increase was primarily
due to continued strong growth throughout 1999 compared to weaker results and
losses in 1998 that did not recur. Equities performed well during the six months
ended 30 June 1998, but experienced a more difficult trading environment in the
second half of 1998 as a result of higher volatility levels in equity markets.
In 1999, Equities

--------------------------------------------------------------------------------
 76

UBS
--------------------------------------------------------------------------------

performed strongly in all major markets. Continuing strong secondary cash and
derivatives business with institutional and corporate clients contributed
significantly to the positive results.

Operating income from Fixed Income increased CHF 2,731 million from CHF (267)
million in 1998 to CHF 2,464 million in 1999. The improvement in Fixed Income
largely reflected particularly strong performance in swaps and options and
investment grade corporate debt products during 1999. Strong client flows drove
both investor and issuer activities, resulting in increased revenues. Weaker
than expected results in Fixed Income in 1998 were due primarily to significant
losses in the Group's emerging market portfolio, which were largely attributable
to Corporate and Institutional Clients and a write-down of CHF 790 million in
the division's LTCM trading position.

Operating income from Corporate Finance increased CHF 389 million, or 23.4%,
from CHF 1,665 million in 1998 to CHF 2,054 million in 1999. Strong performance
in mergers and acquisitions, resulting in higher advisory fees, and
contributions from UBS's Equity and Debt Capital Markets Groups were the primary
drivers of the increase.

Operating income from Treasury Products decreased CHF 546 million, or 23.2%,
from CHF 2,351 million in 1998 to CHF 1,805 million in 1999. Foreign exchange
trading, while continuing to be profitable, was adversely affected by diminished
volumes in key markets in 1999. The reduced levels of activity resulted from the
introduction of the euro and narrowing margins from increased competition in the
global markets. Corporate and Institutional Clients' precious metals business
was adversely impacted by the dramatic volatility in the gold market in the
fourth quarter of 1999.

Operating income from the non-core business as identified above increased CHF
778 million from CHF (96) million in 1998 to CHF 682 million in 1999. In 1998,
Equities recognized losses of CHF 762 million from the Global Equity Derivatives
portfolio as compared to 1999, during which this portfolio generated CHF 74
million in positive revenues. The losses recognized in 1998 were partially
offset by CHF 498 million in revenues generated by Global Trade Finance. In
addition, during 1999 the Global Trade Finance business was sold for a CHF 200
gain after generating approximately CHF 160 million in revenues in 1999.

Credit loss expense decreased CHF 170 million, or 34.0%, from CHF 500 million in
1998 to CHF 330 million in 1999. This reflected a decrease in expected credit
losses due primarily to the continued wind-down of the non-core loan portfolio
and the sale of the international Global Trade Finance business in mid-1999. See
"--UBS Switzerland--Private and Corporate Clients" for a discussion of the
impact of the transfer of UBS's Swiss Global Trade Finance business to Private
and Corporate Clients. The non-core loan portfolio will continue to be
wound-down.

Personnel, general and administrative expenses increased CHF 2,474 million, or
36.3%, from CHF 6,816 million in 1998 to CHF 9,290 million in 1999. Despite a
reduction in headcount of 1,100, or 8%, from 13,794 at 31 December 1998 to
12,694 at 31 December 1999, personnel expenses increased CHF 2,528 million, or
58.3%, to CHF 6,861 million in 1999, due primarily to performance-related
compensation tied directly to the strong divisional results for the year. In
addition, in 1998, CHF 1,007 million of accrued payments to personnel was
charged against the restructuring reserve. At the end of 1997, UBS foresaw the
probability of a shortfall in profit in its investment banking business as a
result of the merger. In order to protect its investment banking franchise, UBS
realized it would probably need to make payments to personnel in excess of
amounts determined by normal compensation methodologies. An amount of
approximately CHF 1 billion was recorded as part of the merger-related
restructuring reserve for this purpose. By the third quarter of 1998, this
shortfall had materialized, and the CHF 1,007 million of accrued payments to
personnel were charged against the restructuring reserve as planned. The
shortfall in profits noted above was aggravated by losses associated with LTCM
and the Global Equity Derivatives portfolio. After adjusting 1998 for the

amount charged to the restructuring reserve, personnel expenses in 1999
increased 28.5% against the comparative prior period.

General and administrative expenses remained relatively flat from 1998 to 1999.

Depreciation and amortization increased CHF 71 million, or 10.3%, from CHF 692
million in 1998 to CHF 763 million in 1999, primarily reflecting accelerated
amortization of the goodwill on a Latin American subsidiary.

(1) Certain amounts have been restated to conform to the 2000 presentation.

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Operating
income increased CHF 31 million, or 25.8% from CHF 120 million in the first half
of 1999 to CHF 151 million in the first half of 2000. This reflects an increase
in realized gains resulting from an increased number of sales of investments in
the first half of 2000 as compared to 1999, partially offset by write-downs of
the value of some under-performing companies in the portfolio.

Personnel, general and administrative expenses increased by CHF 16 million, or
26.7%, from CHF 60 million in the first half of 1999 to CHF 76 million in the
first half of 2000. This was mainly driven by bonus expenses. Bonuses are
accrued when an investment is successfully exited, so personnel expenses
increase when divestments occur.

UBS Capital made approximately CHF 0.8 billion of new investments and add-ons
between 31 December 1999 and 30 June 2000, compared to CHF 0.6 billion in the
equivalent period in 1999. UBS Capital is gradually increasing its annual
investment rate, as demonstrated by the higher investment rate in the first half
of 2000 as compared to the first half of 1999. UBS Capital has a target
portfolio book value of approximately CHF 5 billion from its own investments and
CHF 5 billion from third-party funds.

Year to 31 December 1999 Compared to Year to 31 December 1998.  Operating income
decreased CHF 270 million, or 46.2%, from CHF 585 million in 1998 to CHF 315
million in 1999. This reflects a decrease in realized gains resulting from a
reduced number of sales of investments in 1999 as compared to 1998. In 1999,
operating income included CHF 13 million of management fees paid by funds that
UBS manages and sponsors.

Personnel, general and administrative expenses decreased slightly by CHF 5
million, or 3.2%, from CHF 156 million in 1998 to CHF 151 million in 1999. These
expenses remained stable despite the business unit's expansion into new regions
and sectors, the recruitment of new professionals, the high level of investment
activity during 1999 and the associated investment costs. As part of the

--------------------------------------------------------------------------------
 78

UBS
--------------------------------------------------------------------------------

restructuring related to the 1998 merger, one team from UBS Capital moved to
another business unit effective 1 January 1999. This resulted in a lower
headcount during most of 1999 when compared to 1998, and therefore personnel
costs decreased 13.2% from CHF 121 million in 1998 to CHF 105 million in 1999.
General and administrative expenses increased CHF 11 million, or 31.4%, to CHF
46 million in 1999 mainly due to deal-related expenses.

UBS Capital made approximately CHF 1.4 billion of new investments and add-ons
during 1999.

Half Year to 30 June 2000 compared to Half Year to 30 June 1999.  Operating
income increased CHF 40 million, or 43%, from CHF 93 million in the first half
of 1999 to CHF 133 million in the first half of 2000. Revenues have increased as
assets under management have grown and a wider range of products and services
has been offered to clients. With the exception of its business activities in
Germany and Australia, UBS Warburg's Private Clients business is in the
relatively early stages of development and its client relationships have not yet
delivered their full revenue potential. Private Clients opened new offices in
Rome, Madrid, Barcelona and Marbella in January 1999 and in Stuttgart and Paris
in June 1999.

Assets under management increased by CHF 8 billion, or 27.6%, from 30 June 1999
to 30 June 2000, driven primarily by market performance.

Operating expenses increased 62%, or CHF 145 million, from CHF 234 million in
the first half of 1999 to CHF 379 million in the first half of 2000, mainly due
to the expansion of Private Clients' offices during the year. This included a
restructuring charge of CHF 93 million taken as a result of scaling back
operations in certain markets, subsequent to integration of Private Clients into
UBS Warburg in February 2000. CHF 60 million of the charge relates to personnel
costs, the remainder to general and administrative expenses.

Personnel, general and administrative expenses increased CHF 149 million, or
69.0%, from CHF 216 million in the first half of 1999 to CHF 365 million in the
first half of 2000. Personnel costs increased 86.6%, or CHF 116 million, to CHF
250 million in the first half of 2000, versus the first half of 1999, including
the restructuring charge of CHF 60 million as explained above. Excluding this
restructuring charge, personnel expenses increased 41.8% in line with increases
in headcount, and bonus accruals increased in line with improved revenue
performance. General and administrative

expenses increased CHF 33 million, or 40%, from the first half of 1999 to the
first half of 2000, due to the restructuring provision explained above.
Excluding this provision, general and administrative expenses were unchanged,
reflecting continued close management of non-personnel costs in the context of a
growing business.

Year to 31 December 1999 Compared to Year to 31 December 1998.  Results for the
year ended 31 December 1998 are driven by a business consisting primarily of the
private banking operations of Schroder Munchmeyer Hengst, a German private bank
acquired by the former Union Bank of Switzerland in August 1997, domestic
private banking activities in Australia, and limited onshore private banking
activities conducted in the United States and Italy, established by the former
Union Bank of Switzerland.

Operating income increased CHF 4 million, or 2%, from CHF 190 million in 1998 to
CHF 194 million in 1999.

Assets under management increased during 1999 by CHF 9 billion, or 33%.

Operating expenses increased 61%, or CHF 198 million, to CHF 521 million in
1999, as a result of expansion in front-line and support staff, office
locations, and infrastructure related investments.

Personnel, general and administrative expenses increased CHF 187 million, or
64%, from CHF 294 million in 1998 to CHF 481 million in 1999. Personnel costs
increased 57%, or CHF 107 million, to CHF 294 million in 1999 due to an increase
in headcount of 664, or 92%, from 722 at 31 December 1998 to 1,386 at 31
December 1999. General and administrative expenses increased CHF 80 million, or
75%, from 1998 to CHF 187 million in 1999, due to increases in information
technology, property and other infrastructure costs to support the new offices
and increased headcount.

revenues.

Operating expenses were CHF 158 million in the first half of 2000, mainly
related to the hiring of front-line staff as well as infrastructure-related
investments in core technologies. Personnel, general and administrative expenses
were CHF 144 million in the first half of 2000 and CHF 36 million in 1999,

of which CHF 84 million and CHF 18 million were personnel costs. These expenses
are primarily related to

-  the hiring of the management team across a broad range of functions,

-  the establishment of the operations infrastructure, including new call
   centers in Maastricht and Edinburgh,

-  the installation and testing of systems platforms, and

-  the testing of the marketing concept.

Half Year to 30 June 2000 Compared to Half Year to 30 June 1999.  Operating
income before credit loss expense decreased CHF 1,554 million from CHF 1,587
million in the first half of 1999 to CHF 33 million in the first half of 2000,
primarily due to one-time gains on the divestitures of the stake in Swiss
Life/Rentenanstalt of CHF 1,490 million and of Julius Baer registered shares of
CHF 110 million included in the first half of 1999. Operating income before
credit loss expense included CHF 216 million in the first half of 2000, due to
the consolidation of Klinik Hirslanden AG. Other gains and losses attributable
to Corporate Center arise from funding, capital and balance sheet management,
the management of corporate real estate and the management of foreign currency
earnings activities undertaken by Group Treasury.

Credit loss expense in Corporate Center reconciles the difference between
management accounting and financial accounting, that is between the adjusted
expected losses charged to the divisions and the actual credit loss expense
recognized in the Group financial accounts. The Swiss economy has been strong in
the first half of 2000 and has led to lower than expected credit losses, and a
write back of credit loss provisions of CHF 208 million, resulting in a credit
of CHF 621 million in this line.

Personnel, general and administrative expenses increased CHF 486 million, or
267%, from CHF 182 million in the first half of 1999 to CHF 668 million in the
first half of 2000.

Personnel costs increased CHF 208 million, or 254%, in the first half of 2000
from CHF 82 million in the first half of 1999 to CHF 290 million in the first
half of 2000. This increase is largely attributable to the first-time
consolidation of Klinik Hirslanden AG beginning in the second half of 1999.

<PAGE>   114
UBS
--------------------------------------------------------------------------------

General and administrative expenses increased 278%, or CHF 278 million, to CHF
378 million in the first half of 2000 from CHF 100 million in the first half of
1999, primarily as a result of the following items, which were included in
general and administrative expenses for the first half of 2000:

-  an additional charge of CHF 200 million for the U.S. global settlement of
   Holocaust-related claims; and

-  expenses of Klinik Hirslanden AG as a result of the consolidation of this
   entity in the first half of 2000, but not in the first half of 1999.

Depreciation and amortization increased CHF 12 million, or 8.2%, from CHF 146
million in the first half of 1999 to CHF 158 million in 1999, principally
reflecting the inclusion of Klinik Hirslanden AG in the first half of 2000. The
remaining portion of depreciation and amortization includes depreciation of
workstations and information technology equipment, goodwill and other intangible
assets as well as depreciation of other fixed assets.

Year to 31 December 1999 Compared to Year to 31 December 1998.  Operating income
before credit loss expense increased CHF 1,819 million, or 952%, from CHF 191
million in 1998 to CHF 2,010 million in 1999, primarily due to the following:

-  gains on the divestments of Swiss Life/Rentenanstalt of CHF 1,490 million and
   of UBS's interest in Julius Baer registered shares of CHF 110 million
   included in 1999;

-  approximately CHF 380 million due to the first time consolidation of Klinik
   Hirslanden AG included in 1999; and

-  negative impact on 1998 operating income due to the loss of CHF 370 million
   from LTCM.

In addition, revenues attributable to Corporate Center arise from the funding,
capital and balance sheet management, and the management of foreign currency
earnings activities undertaken by Group Treasury.

Personnel, general and administrative expenses decreased CHF 937 million, or
50.2%, from CHF 1,868 million in 1998 to CHF 931 million in 1999.

Personnel costs decreased 56.6% to CHF 92 million in 1999 from CHF 212 million
in 1998 primarily as a result of the recognition in 1999 of pre-paid employer
pension contributions of CHF 456 million. This represents the difference between
previously recorded and actuarially determined pension expenses and was
recognized in 1999 after the resolution of certain legal and regulatory issues.
Excluding the recognition of this benefit, personnel expenses increased from
1998 to 1999 despite a slight decrease in headcount from 921 in 1998 to 862 in
1999. This increase year-on-year is largely attributable to the first-time
consolidation of Klinik Hirslanden AG in 1999.

General and administrative expenses decreased CHF 817 million, or 49.3%, to CHF
839 million in 1999 from CHF 1,656 million in 1998, primarily as a result of a
charge for the U.S. global settlement of Holocaust-related claims of CHF 842
million in 1998. In addition, the following items were included in general and
administrative expenses for 1999:

-  an additional charge of CHF 154 million related to the settlement of
   Holocaust-related claims in the United States;

-  an additional pre-tax restructuring charge of CHF 300 million in respect of
   the 1998 merger; and

-  expenses of Klinik Hirslanden AG as a result of the first-time consolidation
   of this entity in 1999.

In addition, total operating expenses in Corporate Center were reduced from 1998
to 1999 mainly due to a further refinement of service level agreements with the
business groups.

UBS
--------------------------------------------------------------------------------

Depreciation and amortization increased CHF 201 million, or 93.5%, from CHF 215
million in 1998 to CHF 416 million in 1999, principally as a result of a
reclassification of certain items which appeared in general and administrative
expenses in 1998.

Divisional Results for Year Ended 31 December 1998 Compared to Year Ended 31
December 1997

Results for the year ended 31 December 1998 compared to year ended 31 December
1997 are shown in terms of the old divisional structure which existed at that
time, and without taking account of the accounting changes implemented during
2000.

The principal differences from the current structure were that the UBS Asset
Management Investment Funds business unit and the UBS Warburg Private Clients
business unit were part of the Private Banking Division, and their results are
included within that division. In addition, UBS Warburg's UBS Capital business
unit was an autonomous division, and UBS Warburg itself consisted only of what
is now the UBS Warburg Corporate and Institutional Clients business unit. The
e-services business did not exist in 1998 or 1997.

(1)  Prior to the 1998 merger, the businesses were reported under different

     accordance with UBS's current management reporting structure is, therefore,
     not possible.

Total operating income before credit loss expense increased slightly from CHF

in 1997 was a CHF 97 million pre-tax gain on the sale of Bank Aufina AG.

UBS
--------------------------------------------------------------------------------

increase in operating income before credit loss expense from 1997 to 1998
excluding the gains from the divestitures was primarily attributable to improved
margins resulting from risk-adjusted pricing.

Private and Corporate Clients' credit loss expenses increased CHF 78 million, or
7.1%, from CHF 1,092 million in 1997 to CHF 1,170 million in 1998, reflecting
increased loss expectations.

Personnel, general and administrative expense decreased CHF 234 million, or
5.2%, from CHF 4,497 million in 1997 to CHF 4,263 million in 1998. This decrease
primarily reflected reduced costs due to a reduction in headcount from 25,641 in
1997 to 24,043 in 1998 resulting from the sales of Boss Lab SA and Bank
Prokredit AG and additional reductions from the closing of redundant branches.

</TABLE>

Operating income increased CHF 1,041 million, or 16.9%, from CHF 6,156 million
in 1997 to CHF 7,197 million in 1998. This increase primarily reflected
non-recurring gains of CHF 1,058 million realized on the sales of BSI and Adler.
Excluding these gains from 1998 operating income, operating income decreased
marginally from 1997 to 1998. The decrease primarily reflected adverse market
conditions in the second half of 1998. Despite this difficult environment and
the occurrence of the 1998 merger on 29 June 1998, Private Banking was able to
maintain relatively stable performance, with assets under management decreasing
only slightly from CHF 610 billion at 31 December 1997 to CHF 607 billion at 31
December 1998.

Personnel, general and administrative expenses decreased CHF 134 million, or
4.7%, from CHF 2,869 million in 1997 to CHF 2,735 million in 1998. Headcount
decreased 2.9% from 7,862 at 31 December 1997 to 7,634 at 31 December 1998.
Headcount in Switzerland, along with related personnel costs, decreased
primarily from the sales of BSI and Adler. This decrease was partially offset by
an increase in headcount outside of Switzerland due to the development of UBS's
private banking business outside of Switzerland.

</TABLE>

Operating income increased CHF 123 million, or 11.8%, from CHF 1,040 million in
1997 to CHF 1,163 million in 1998, reflecting growth in assets under management
from UBS Asset Management's acquisition in Japan and positive market
performance. Non-institutional assets under management, including assets from
Private Banking, increased CHF 40 billion, or 30.5%, from 1997 to 1998. These
positive developments were partially offset by a decline in the U.K. business's
operating income and assets under management due to short-term performance
issues and a very competitive U.K. marketplace.

Personnel, general and administrative expenses increased CHF 66 million, or
12.2%, from CHF 542 million in 1997 to CHF 608 million in 1998. This increase
reflects the expansion in Europe and the acquisition of Long-Term Credit Bank of
Japan's asset management business during 1998. Principally as a result of these
expansions, headcount increased 9.8% from 1,364 at 31 December 1997 to 1,497 at
31 December 1998.

Depreciation and amortization increased CHF 12 million, or 12.6%, from CHF 95
million in 1997 to CHF 107 million in 1998. This increase reflects an increase
in goodwill amortization due to additional goodwill recorded in 1998 upon the
payment of the remaining obligation to the previous owners of Brinson Partners.

------------
(1)  Prior to the 1998 merger, these businesses were reported under different
     management reporting structures. A breakdown of 1997 operating income in
     accordance with UBS's current management reporting structure in effect for
     1998 was, therefore, not possible.

Total operating income before credit loss expense decreased CHF 3,901 million,
or 35.8%, from CHF 10,888 million in 1997 to CHF 6,987 million in 1998, with
decreases recognized across all business areas. Equities experienced a difficult
trading environment in the second half of 1998 in addition to recognizing net
losses on the Global Equity Derivatives portfolio of CHF 762 million, although
this was offset somewhat by high commission levels and income from new issues.
Fixed Income's operating income decreased from 1997 to 1998 due to the writedown
in 1998 of UBS's holdings in LTCM by CHF 790 million and CHF 725 million in
emerging markets. This emerging markets loss consisted of CHF 455 million in
losses in Russia, CHF 215 million in Latin America and CHF 55 million in Asia
and other Eastern European countries. These losses were somewhat offset by
strong primary and secondary bond activity.

Corporate Finance exceeded expectations in 1998 resulting from strong mergers
and acquisitions activity and improved results from equity and equity-linked
issues. In 1997 and 1998, Treasury Products performed well in cash and
collateral trading, as well as in foreign exchange.

Credit loss expense increased CHF 200 million, or 66.7%, from CHF 300 million in
1997 to CHF 500 million in 1998. This increase resulted from increased exposures
from the start-up of the leveraged finance business in early 1998 and an
increase in over-the-counter derivatives exposures due primarily to counterparty
and country rating downgrades resulting from the Asian and Russian crises.

Personnel, general and administrative expenses decreased CHF 1,825 million, or
21.1%, from CHF 8,641 million in 1997 to CHF 6,816 million in 1998. This
primarily reflected a reduction in personnel related costs resulting from a
reduction in headcount by 25.9% from 18,620 at 31 December 1997 to 13,794 at 31
December 1998 as a result of the merger. Merger integration for UBS Warburg in
connection with the 1998 merger was substantially completed during 1998. As
discussed above, CHF 1,007 million of accrued payments to personnel were charged
against the restructuring reserve in 1998. Adjusting 1998 for this amount,
personnel expenses decreased from 1997 by 9.5%.

Depreciation and amortization increased CHF 24 million, or 3.6%, from CHF 668
million in 1997 to CHF 692 million in 1998. This reflected increased goodwill
amortization in 1998 due to the acquisition of Dillon Read & Co., Inc. in
September 1997 and the accelerated amortization of

goodwill on Russian and Brazilian subsidiaries of CHF 35 million due to weak
market conditions in these countries in 1998.

Investments (at book value).................................   1,748      1,080
</TABLE>

Operating income increased CHF 93 million, or 18.9%, from CHF 492 million in
1997 to CHF 585 million in 1998, reflecting generally favorable conditions in
Western markets allowing for the disposals of investments in Switzerland, the
United States, and the Benelux and Nordic region. UBS Capital's portfolio in
1998 was, and it continued to be during 1999, primarily focused on the United
States and Western Europe with minor exposure to Latin America and Asia.
Therefore, the emerging markets crises which took place during 1998 had little
impact on the division's performance.

Personnel, general and administrative expenses increased CHF 46 million, or
41.8%, from CHF 110 million in 1997 to CHF 156 million in 1998. Higher
performance-related compensation in 1998 than in 1997 primarily resulted from
the stronger performance in 1998. Staff losses due to the merger were minimal.

UBS Capital made investments totaling approximately CHF 800 million during 1998
compared to approximately CHF 600 million during 1997, further demonstrating
steady growth in its investment rate.

million charge resulting from the write-down in 1998 of UBS's investment in
LTCM. In addition, revenues attributable to Corporate Center arise from the
funding, capital and balance sheet management, and the management of foreign
currency earnings activities undertaken by Group Treasury.

Personnel, general and administrative expenses increased CHF 1,640 million, or
763%, from CHF 215 million in 1997 to CHF 1,855 million in 1998, primarily
resulting from a CHF 842 million provision taken in 1998, for the settlement in
the United States of the Holocaust-related litigation, additional provisions for
litigation and adjustments to the pricing of interdivisional allocations on the
basis of service level agreements.

Depreciation and amortization decreased CHF 1 million, or 0.5%, from CHF 216
million in 1997 to CHF 215 million in 1998. This represented the charge for
depreciation on goodwill and intangibles, information technology infrastructure,
real estate and other fixed assets.

UBS Financial Targets

UBS focuses on four key financial targets. These targets are to achieve:

- A pre-goodwill return on equity, or "RoE," averaging between 15% and 20%,
  across periods of varying market conditions.

- Double-digit average annual growth in pre-goodwill earnings per share, across
  periods of varying market conditions.

- Focus and downward pressure on UBS's cost/income ratio.

- Strong growth in net new money in UBS's private client businesses.

Adjusted for the final provision of CHF 200 million relating to the U.S. global
settlement, UBS's annualized pre-goodwill return on equity for the first six
months of 2000 was 31.9%. Pre-goodwill earnings per share grew 92% over the
first six months of 1999, adjusted for divestments and one-off provisions,
reaching UBS's target of double-digit growth. UBS's cost/income ratio is well
below that of the first half of 1999. After a positive start to the year, net
new money in the private client businesses was slightly negative in the second
quarter of 2000, against a more muted market background for asset growth than
the first quarter.

THERE CAN BE NO ASSURANCE THAT UBS WILL BE ABLE TO ACHIEVE ITS FINANCIAL
TARGETS, AND THESE TARGETS ARE SUBJECT TO CHANGE AT THE DISCRETION OF UBS'S

INCLUDING THE FACTORS REFERRED TO UNDER "CAUTIONARY NOTE REGARDING FORWARD-
LOOKING INFORMATION."

Liquidity and Capital Resources

Group liquidity and capital management is undertaken at UBS by Group Treasury as
an integral asset and liability management function. For a detailed discussion
of UBS's asset and liability management, see "--Asset and Liability Management"
and for a detailed discussion of UBS's liquidity risk management, see "--Asset
and Liability Management--Liquidity and Funding Management."

Consolidated Cash Flows.  In the half year to 30 June 2000, cash equivalents
decreased CHF 13,788 million, principally as a result of operating activities.
UBS's net profit of CHF 4,268 million was more than offset by a high net cash
outflow for repurchase and reverse repurchase agreements, cash collateral on
securities borrowed and lent and for investments in trading positions. Negative
cash flow of CHF 2,293 million from investing activities was principally due to
the purchase of financial investments. Net cash inflow from financing activities
of CHF 14,507 million was principally generated

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

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

by the issuance of CHF 20,754 million in money market paper and CHF 7,452
million in long-term debt, offset by the repayment of CHF 10,794 million of
long-term debt, dividend payments of CHF 2,164 million and treasury share
transactions.

UBS generated significant positive cash flow during the year ended 31 December
1999 resulting in a net increase in cash equivalents of CHF 18,599 million.
Operating activities provided a net cash flow of CHF 3,338 million during the
year ended 31 December 1999. The strong positive results and reduction in UBS's
customers' loan exposures at UBS Warburg during the year, offset in part by a
net cash outflow from trading-related balances, generated the net positive cash
flow from operating activities. Net cash from investing activities included cash
outflows due to the purchase of property and equipment and investments in
subsidiaries and associates, which were more than offset by positive cash flows
generated from the sale of subsidiaries and associates, property and equipment
and financial investments. The net cash inflow from financing activities was
principally due to the issuance of CHF 13,128 million in money market paper and
CHF 12,661 million in long-term debt which was partially offset by the payment
of dividends, treasury share transactions, the repayment of CHF 7,801 million in
long-term debt and minority interests.

During the year ended 31 December 1998, UBS's net cash outflows from operating
and financing activities more than offset its net cash inflow from investing
activities resulting in a decrease in UBS's cash equivalents of CHF 8,675
million. The main contributor to the net decrease in cash equivalents was the
negative cash flow from financing activities of CHF 12,335 million. This
negative cash flow was primarily due to the repayment of long-term debt, the
reduction in money market paper outstanding, the payment of dividends and
treasury share transactions, partially offset by the issuance of long-term debt.
Positive net cash flow from investing activities resulted primarily from the
sale and maturity of financial investments.

During the year ended 31 December 1997, UBS's net cash outflows of CHF 35,895
million from operating and investing activities more than offset UBS's net cash
inflow from financing activities of CHF 29,015 million resulting in a decrease
in cash equivalents of CHF 7,451 million. UBS's operating activities generated
negative net cash flow principally due to a net increase in its trading related
balances which was only partially offset by strong operating results before the
restructuring reserve. Investing activities generated a net cash outflow of CHF
1,671 million during the period primarily due to the purchase of property and
equipment and financial investments. Net cash inflow from financing activities
resulted principally from the issuance of long-term debt and money market paper.

Capital Resources.  Capital management is undertaken at UBS by Group Treasury as
an integral asset and liability management function. UBS does not have any
material commitments for capital expenditures as of 30 June 2000. UBS's overall
capital needs are continually reviewed to ensure that its capital base can
appropriately support the anticipated needs of the divisions as well as the
regulatory capital requirements. See "--Asset and Liability Management."

The Bank for International Settlements, or "BIS," is an international
organization fostering the cooperation of central banks and international
financial institutions. Among other activities, it provides guideline formulas
for evaluating capital adequacy.

As the following table shows, UBS's BIS Tier 1 Ratio increased from 9.3% at 31
December 1998 to 10.6% at 31 December 1999 primarily resulting from a
significant increase in retained earnings coupled with a reduction in risk
weighted assets. The decrease in risk weighted assets is principally a result of
reduced positive replacement values, off balance sheet contingent liabilities
and the reduction in the size of the international loan book.

UBS's BIS Tier 1 Ratio has continued to increase, from 10.6% at 31 December 1999
to 12.1% at 30 June 2000. The effect of UBS's share buy back program was more
than offset by a significant increase in UBS's retained earnings as well as a
further reduction in risk weighted assets.

</TABLE>

------------
(1) Gives effect to the combined pro forma financial position of UBS and
    PaineWebber.

The ratios measure capital adequacy by comparing UBS's eligible capital with the
risk-weighted asset positions, which include balance sheet assets, the net
positions in securities not held in the trading portfolio, off-balance sheet
transactions converted into their credit equivalents and market risk positions
at a weighted amount to reflect their relative risk. See Note 33c in UBS's
consolidated financial statements for additional information on capital
adequacy.

The calculation of capital requirements applicable to UBS under the Swiss
Federal Banking Commission's regulations differs in certain respects from the
calculation under the BIS guidelines. Most importantly:

- where the BIS currently does not apply risk weightings above 100% to any asset
  category, the Swiss Federal Banking Commission applies risk weightings of
  greater than 100% to certain kinds of assets (for example, real estate, bank
  premises, other fixed assets, equity securities and unconsolidated
  participations); and

- where the BIS guidelines apply a 20% risk weighting to obligations of OECD
  banks, the Swiss Federal Banking Commission's regulations apply risk
  weightings of 25% to 75% (depending upon maturities) to obligations of OECD
  banks.

As a result of these differences, UBS's risk-adjusted assets are higher, and its
ratios of total capital and Tier 1 capital are lower, when calculated pursuant
to the Swiss Federal Banking Commission's regulations as compared to the BIS
guidelines. However, since the BIS and Swiss Federal Banking Commission first
implemented their risk-based capital guidelines and regulations in 1987, UBS and
its predecessor banks have always had total capital and Tier 1 capital in excess
of the minimum requirements of both the BIS and the Swiss Federal Banking
Commission. For the years ended 31 December 1998 and 31 December 1999 and the
six-months ended 30 June 2000, UBS has maintained significant levels of total
capital and Tier 1 capital in excess of the minimum requirements of both the BIS
and the Swiss Federal Banking Commission. Although no assurance can be given
that UBS will continue to have total capital and Tier 1 capital in excess of the
minimum requirements of both the BIS and the Swiss Federal Banking Commission,
UBS does not expect that credit losses, risk-weighted asset growth and similar
events will eliminate UBS's excess total capital or Tier 1 capital.

UBS
--------------------------------------------------------------------------------

UBS is committed to maintaining a strong capitalization and rating as a
distinguishing characteristic of UBS for both clients and shareholders. On 12
March 1999, UBS introduced a treasury stock buy-back program, which was intended
to run for a period of two years. At 31 December 1998, UBS held 8,300,300
shares, as adjusted for the two-for-one stock split that became effective on 8
May 2000, or 2% of its outstanding shares, as treasury stock. As of 31 December
1999, a total of 15,660,220 shares, as adjusted for the two-for-one stock split,
or 3.6%, had been acquired as treasury stock. This amount includes 1,053,082
shares that are at the disposal of UBS's Board of Directors. The objective of
the buy-back program was to utilize the shares for acquisitions and the employee
stock ownership program. UBS has subsequently concluded that this program was
too limited for its purposes because of the continuous increase in capital that
was projected to arise from on-going retained earnings, the selective reduction
in the risk profile and increasing capital efficiency.

For this reason, UBS announced in December 1999 that it would replace the
treasury stock buy-back program with a Swiss-specific program targeted at Swiss
institutional shareholders, which is the only tax-efficient means that has been
identified to achieve cancellation. This is called a "second trading line"
program. At UBS's annual shareholders' meeting on 18 April 2000, shareholders
approved the repurchase of shares up to a maximum amount of CHF 4 billion,
through the second trading line program. The second trading line program was
implemented in January 2000 and concluded on 28 June 2000. During this time UBS
repurchased 18,421,783 shares, representing 4.3% of its share capital, at an
average price of CHF 217.00. The final cancellation of the shares bought back
through the second trading line requires shareholders' approval which the board
of directors will seek at the annual general meeting scheduled for April 2001.

Balance Sheet.  UBS maintains a significant percentage of liquid assets,
including collateralized receivables and trading portfolios that can be
converted into cash on relatively short notice and with a limited impact on
UBS's results in order to meet short-term funding needs. Collateralized
receivables include reverse repurchase agreements and cash collateral on
securities borrowed which are secured by U.S. government and agency securities,
and marketable corporate debt and equity securities and a portion of UBS's loans
and due from banks which are secured primarily by real estate. The value of
UBS's collateralized receivables and trading portfolio will fluctuate depending
on market conditions and client business. The individual components of UBS's
total assets may vary significantly from period to period due to changing client
needs, economic and market conditions and trading strategies.

Total assets increased CHF 47,419 million, or 5.3%, at 30 June 2000 compared to
total assets at 31 December 1999. This was principally a result of an increase
in cash collateral on securities borrowed, reverse repurchase and trading
portfolio assets, which was partially offset by significant decreases in cash
and balances with central banks and money market paper as liquidity levels were
adjusted following Y2K, a reduction in positive replacement values resulting
from decreases in derivative products, and decreases in amounts due from banks.

Total liabilities increased CHF 46,151 million, or 5.3%, at 30 June 2000,
compared to total liabilities at 31 December 1999, principally due to a
significant increase in amounts due under repurchase agreements, cash collateral
on securities lent and trading portfolio liabilities and an increase in money
market paper issued, offset in part by a decrease in negative replacement values
resulting from decreases in derivative products.

In the course of the first half of 2000, UBS's long-term debt portfolio
decreased from CHF 56.3 billion at 31 December 1999 to CHF 53.0 billion at 30
June 2000. During this half year CHF 7,452 million of long-term securities were
issued while CHF 10,794 million matured. UBS believes the maturity profile of
the long-term debt portfolio is well balanced with slight bias towards
shorter-term maturities to match the maturity profile of UBS's assets.

Shareholders' equity increased CHF 1,268 million, or 4.1%, from 31 December 1999
to 30 June 2000. The increase in treasury shares was more than offset by the
increase in net income, resulting in a steady increase in total shareholders'
equity.

Credit Ratings.  UBS uses the debt capital markets to fund a significant portion
of its operations. The cost and availability of debt financing is influenced by
UBS's credit ratings. Credit ratings are also important in certain markets and
in entering into certain transactions, such as derivative transactions. A
reduction in UBS's credit ratings could increase its borrowing costs and limit
its access to the capital markets. UBS has been able to maintain strong credit
ratings over the past few years, even during periods of a difficult trading
environment.

The following table sets forth UBS's credit ratings on its long-term debt as of
30 June 2000 and 31 December 1999 and 1998.

Each of these ratings reflects only the view of the applicable rating agency at

rating may be obtained only from such rating agency. There is no assurance that
any such credit rating will remain in effect for any given period of time or
that such rating will not be lowered, suspended or withdrawn entirely by the
applicable rating agency, if in such rating agency's judgment, circumstances so
warrant.

Recent Accounting Developments

For a discussion of recent accounting developments, including those that have
not yet been adopted, see Note 1 to UBS's consolidated financial statements,
which are included elsewhere in this document.

Risk Management

The risk management process is an integral part of UBS's commitment to providing
consistent high quality returns for its shareholders. UBS believes that the
delivery of superior shareholder returns depends on achieving an appropriate
balance between risk and return. This requires a management process that gives
appropriate focus to risk as well as returns and which integrates this approach
with the management of UBS's balance sheet and capital. For this reason, UBS
restructured the Corporate Center in the course of 1999 to establish an
integrated group-wide function under the Chief Financial Officer, or "CFO," to
address all aspects of finance, strategic planning, risk control and balance
sheet and capital management.

<PAGE>   126
UBS
--------------------------------------------------------------------------------

The approach to risk management and control at UBS recognizes that risk is
integral to its business. UBS's risk processes, which have evolved over a number
of years, seek to limit the scope for adverse variations in UBS's earnings and
in particular to protect UBS from the risk of loss in the event of unlikely, but
possible, stress scenarios arising from any of the material risks which it
faces. UBS's Risk Policy Framework focuses on the procedures for managing and
controlling the risks that can affect the volatility of earnings from period to
period, and distinguishes between the following three types of risk:

-  Primary risks: risks inherent in the businesses that UBS undertakes. The
   principal primary risks are credit risk and market risk.

-  Group risks: risks that UBS faces at the Group level in managing its business
   and balance sheet. Principal group risks are tax risk, liquidity and funding
   risk and residual balance sheet related interest rate risk.

-  Consequential risks: risks that UBS faces as a consequence of the operational
   activities it undertakes to provide services to customers. This is sometimes
   referred to as "operational risk." Principal consequential risks are
   transaction processing risk, legal risk, compliance risk, liability risk and
   security risk.

UBS's risk framework recognizes that an effective risk management and control
process depends on sound processes to identify risks, and to establish and
maintain limits and procedures to control these risks. UBS's Chief Risk Officer,
or "CRO," has overall responsibility for ensuring that the limits and procedures
are appropriate and are adhered to for risks other than credit risk. The Chief
Credit Officer, or "CCO," has overall responsibility for ensuring that the
limits and procedures are appropriate and are adhered to for credit risk. Credit
risk remains the single largest risk that UBS faces. The limits and procedures
are designed to keep UBS's risk exposures within the parameters determined by
the UBS Board of Directors. These limits and procedures take into account not
only the external environment that UBS faces, but also UBS's internal
capabilities to manage the risk, including issues such as the availability of
appropriate information processing systems and the availability of suitably
qualified staff to manage and control the risk.

The Board of Directors establishes the risk parameters within which UBS operates
and reviews a report on UBS's risk profile from the CCO and the CRO on at least
a quarterly basis. The Board of Directors establishes two limits: normal
earnings volatility and potential losses under a stress scenario. UBS's risk
appetite defines the amount of earnings volatility that the Board of Directors
deems to be acceptable in normal market conditions in order to achieve
divisional growth targets. This potential volatility is measured by the risk
control organization using measures that estimate statistically possible losses.
Value at risk, or "VaR," methodology is the principal quantitative measure UBS
uses for evaluating risk.

UBS's risk bearing capacity seeks to establish a limit to the potential scale of
the loss that UBS might face in unlikely but possible stress situations. Stress
loss limits are set by the Board of Directors taking into account UBS's overall
earnings capacity. They are set in order to protect UBS from unacceptable damage
to annual earnings, dividend paying capability, business viability and
reputation. UBS currently adopts this approach to risk limits in the context of
its trading activities and its country risk credit exposure. In addition, the
Board of Directors approves UBS's key risk policies and the Chairman's office
maintains an ongoing oversight of the integrity of the risk management and
control processes through UBS's internal audit function.

The responsibility for implementing the risk framework on a day to day basis is
delegated by the Board of Directors to the Group Executive Board, which
allocates risk limits to the divisions and monitors UBS's aggregate risk profile
on an ongoing basis. The Group Executive Board, together with

--------------------------------------------------------------------------------
 94
<PAGE>   127
UBS
--------------------------------------------------------------------------------

the CRO and CCO, constitutes itself as UBS's Risk Council and usually meets
twice a month to review outstanding risk issues, large exposures and significant
transactions. In addition, the Group Executive Board has established a Group
Risk Committee and a Group Governance Committee. These committees, which meet
quarterly, consist of representatives of the risk control organization at the
Corporate Center and from the business groups and consider issues relating to
the implementation and development of the risk framework.

Each business group also has a risk management and control structure in place
which is appropriate to its particular business profile. The CRO and CCO have
risk control staff who are located in each business group and who are
responsible for ensuring that the business group implements the Group-wide risk
policies and procedures appropriately. They ensure that all risks are adequately
taken into account in assessing the risk profile of the business groups'
business activities. The focus is on identifying those infrequent events with a
potentially severe impact. In addition, each business group has its own
structure of risk management and governance committees. This is designed to
ensure that there is an ongoing review of the risk profile that the business
group faces in new business initiatives and in large and complex transactions
and that any requirement for amendments to risk policies or limits is identified
and, where appropriate, is escalated in a timely manner to the Group Executive
Board.

Analysis of Risks

Within UBS's risk framework, UBS has identified a number of risk factors as
being of particular importance to its business. The following section summarizes
the main trends and developments in the key risks that UBS faces.

Credit Risk.  Credit risk is the risk of loss resulting from the default of an
obligor or counterparty. UBS's definition of credit risk includes counterparty
and country transfer risk, as well as settlement risk. Credit risk is inherent
in traditional banking products, such as loans and commitments to lend money in
the future or contracts to support clients' obligations to third parties, such
as letters of credit. Credit risk is also inherent in derivative contracts and
other traded products, such as bonds and equity investments. In view of the
significance of credit risk for UBS, the approval and monitoring of new
transactions giving rise to credit risk plays a central part in UBS's risk
control process. Credit approval authorities are exercised independently from
the business units. Credit authority is dependent on the amount involved,
quality, security and tenor of the transaction as well as on the experience and
competence of the credit professionals entrusted with this function.

In order to manage UBS's exposure to credit risk effectively, and in particular
to encourage appropriate pricing of transactions involving credit, UBS measures
its exposure to credit risk using a forward looking statistical estimate of the
expected loss based on the estimated probability of default of UBS's
counterparties. Such estimates are based on the volume and type of exposure, the
value of potential collateral or support, and the quality of each counterparty.
The quality of the counterparty is expressed in a rating with a specific default
probability. For this purpose, UBS classifies all counterparties into a 14 point
rating scale and the transfer risk into a 15 point country rating scale.

Composition of Credit Risk.  Credit risk is assumed, as an integral part of
their business, by UBS Warburg and UBS Switzerland.

The composition of UBS's credit exposure differs appreciably between these two
business groups. At 30 June 2000, a substantial majority of UBS Warburg's
counterparties fell into the internal counterparty rating categories C1-C5 both
with respect to banking products (83%) and the traded products portfolio (97%).
UBS's internal rating classes C1-C5 compare to Moody's Investor Services ratings
Aaa to Baa3 and are considered investment grade. UBS Warburg's counterparties
are primarily sovereigns, insurance companies, financial institutions,
multi-national corporate clients and investment

funds. UBS Warburg's exposure to lower rated customers is generally
collateralized or otherwise structurally supported. UBS's aggregate, unsecured
exposure to hedge funds measured in terms of net replacement value amounted to
USD 5 million at 30 June 2000 compared to USD 55 million at 31 December 1999 and
USD 81 million at 31 December 1998.

By contrast, the largest single component of the loan portfolio within UBS
Switzerland consists of residential mortgage lending in Switzerland, over half
of which is classified within UBS's lowest internal investment grade rating
class of C5. The rating of the remainder of the Swiss portfolio, excluding
mortgages, is fairly widely spread with the largest concentration being in
rating classes C3-C5 comparable to Moody's rating of A2 to Baa3. Credits to
Private Clients are predominately extended against the pledge of marketable
securities and against single-family real estate property.

The continued improvement in the Swiss economy and property markets has aided in
the overall improvement in the quality of this portfolio. UBS Switzerland's
largest exposure at 30 June 2000 was to private households in Switzerland.

Loan Portfolio.  The UBS Warburg loan portfolio remained unchanged during the
first half of 2000. In 1999 this portfolio had been significantly reduced. This
was a continuation of the strategy that began immediately after the 1998 merger
with the objective of improving the risk/reward profile of the international
lending business. This initiative included the shift in focus away from Emerging
Markets and into high quality credits in the major OECD (Organization for
Economic Cooperation and Development) countries and the sale of the non-Swiss
portion of the Global Trade Finance business.

The overall impact of this shift has been a reduction in UBS Warburg's
international banking portfolio (consisting of loans and unfunded commitments to
corporates and institutional clients, excluding banks) from over CHF 250 billion
at June 1998 to CHF 96 billion by 30 June 2000 (CHF 99 billion by 31 December
1999).

The following table shows UBS's loan portfolio and related allowances and
provisions by business groups at 30 June 2000 and 31 December 1999.

See "--Selected Statistical Information--Loans" for a breakdown of the loan
exposure by type of borrower.

Over-the-Counter Derivative Contracts.  A significant proportion of UBS
Warburg's credit risk arises from its trading activities, including its trading
of derivative products. The provision of risk management solutions that involve
the use of derivative products is a core service that UBS offers to its clients.
Derivative products by their nature are particularly sensitive to changes in
market prices and consequently UBS pays close attention to the management and
control of these risks. UBS's credit standards for entering into unsecured
derivative contracts are very high and particular emphasis is placed on the
maturity profile. Ninety-seven percent of UBS Warburg's credit risk on
derivative products falls within UBS's internal rating classes C1-C5.
Transactions with counterparties of lower quality are generally conducted only
on a secured basis. A new system has been introduced in February 2000 to monitor
credit risk exposure to derivative contracts on the basis of a statistically
calculated potential exposure, or Potential Credit Exposure or "PCE," which will
allow an even more precise valuation of the credit equivalents.

Settlement Risk.  Due to UBS's international business, UBS is also exposed to
settlement risk. Settlement risk arises in transactions involving the exchange
of values where a counterparty fails to honor its obligation to deliver cash or
securities. This risk is particularly significant in relation to foreign
exchange and precious metals transactions. UBS limits its exposure to settlement
risk by tolerance levels assigned to each counterparty in relation to its
rating. In addition, UBS monitors this risk on a permanent basis and seeks to
shorten, as much as practicable, the period during which UBS is exposed. UBS has
also been an active participant in an industry initiative to establish a new
organization, called CLS Bank, which is being established in order to
substantially reduce settlement risk between major international financial
institutions. Participation in regulated payment and securities clearing systems
also reduces settlement exposure.

Country Risk Exposure.  UBS's definition of country risk comprises all
cross-border exposures from loans, derivative products and trading products.
This definition includes its own intracompany cross-border positions, which
amounted to CHF 419 billion at 30 June 2000, about 49% of the total non-
emerging market country risk exposure of CHF 851 billion. At 30 June 2000, 98.0%
of UBS's country risk exposure was included in its three highest internal
ratings classes. This portion of UBS's country risk exposure was with OECD
countries where the risk of default is judged to be negligible. The following
table summarizes UBS's country transfer risk exposure grouped by rating classes
as of 30 June 2000 compared to 31 December 1999 and 31 December 1999 compared to
31 December 1998.

The remaining 2.0%, or CHF 17.4 billion, of UBS's country risk exposure is to
emerging markets that are classified in rating classes S3 to S14. This exposure
has decreased as a result of the restructuring of the international loan
portfolio and the exit from the non-Swiss Global Trade Finance business in 1999.
Total exposure to the emerging markets group of countries fell by CHF 7.2
billion between 31 December 1999 and 30 June 2000 -- a reduction of 29% -- and
by CHF 15.0 billion between 31 December 1998 and 30 June 2000 -- a reduction of
46%. In view of the higher risk associated with emerging markets, UBS closely
monitors this exposure on an ongoing basis within the country limits approved by
the Board of Directors. All significant new transactions in emerging and
distressed markets require approval from the respective country risk manager in
addition to the standard counterparty credit approval. The country risk limit
operates as the primary limit for such transactions and extension of credit may
be denied on the basis of a country risk limit even though adequate counterparty
limits may be available for the customer concerned.

The following table analyzes the emerging markets exposures by the major
geographical areas as of 30 June 2000 compared to 31 December 1999 and 31
December 1999 compared to December 1998.

Impaired loans were reduced from 31 December 1998 to 31 December 1999 by
approximately CHF 1.4 billion and non-performing loans by about CHF 1 billion.

See "--Selected Statistical Information--Cross-Border Outstandings" for
additional details on UBS's country risk exposures.

Impaired and Non-Performing Loans.  UBS classifies a loan as impaired when it
determines that there is a high probability that UBS will suffer a partial or
full loss. A provision is then made with respect to the probable loss to be
incurred for the loan in question. Within this category, non-performing loans
are defined as loans where payment of interest, principal or fees is overdue for
90 days.

The following table provides a breakdown by business groups of the impaired and
non-performing loans as of 30 June 2000 and 31 December 1999. UBS Asset
Management did not have any impaired loans or non-performing loans in any of the
periods presented.

Non-performing loans have decreased to CHF 12,085 million at 30 June 2000 from
CHF 13,073 million at 31 December 1999. This positive result was principally due
to the unexpectedly strong performance of the economy in Switzerland, especially
in the second quarter. Previous provisions were established against a background
of several years of relatively low growth in the Swiss economy and relatively
high credit losses. Since the beginning of this year, the Swiss economy started
improving, and accelerated further during the last quarter, with the Swiss
National Bank recently raising its 2000 growth forecast from 1.8% to 3.0%. In
particular, this turnaround has affected real estate values and the real estate
construction market, which has led to recoveries of provisions against loans in
these portfolios. UBS expects to recognize additional recoveries if current
economic trends continue. Non-performing loans decreased to CHF 13,073 million
at 31 December 1999 from CHF 16,113 million at 31 December 1998. The reduction
reflects an accelerated writedown in the Swiss domestic portfolio, a substantial
reduction in UBS's emerging markets exposure, a significant improvement in the
macroeconomic situation in Switzerland and a faster than expected recovery in
key Asian economies.

Allowances and Provisions.  The adequacy of the allowances and provisions that
UBS makes for impaired loans is assessed by the Credit Risk Management and
Control function which is independent from the business units. Allowances and
provisions are determined based upon an individual assessment of counterparties
and countries and their creditworthiness as well as the amount of collateral
available to UBS to offset against the probable loss. UBS believes that the
probable losses in its portfolio are adequately covered by its allowances and
provisions.

30 June 2000 and 31 December 1999 and 1998.

</TABLE>

The allowances and provisions for credit losses decreased CHF 1,008 million, or
7.5%, from CHF 13,398 million at 31 December 1999 to CHF 12,390 million at 30
June 2000. During the first half of 2000, UBS realized a decrease in credit loss
allowances of CHF 83 million compared to an increase of CHF 956 million for
1999. This positive result was essentially due to the continuous strong economy
in Switzerland, where recoveries and write-backs of previously established
provisions by far exceeded new provisioning requirements. The Swiss economy is
expanding at the fastest rate in a decade and accelerated further during the
quarter. The growth is broadly supported, especially in the domestic sector, and
was markedly higher than what could have been expected in 1999.

The development of the total credit loss expense in 1998 and 1999 includes the
effect of allocations from the special reserve pools that had been established
in 1996, prior to the 1998 merger, by both Union Bank of Switzerland and Swiss
Bank Corporation totaling some CHF 5.5 billion. These reserves were established
in recognition of the fact that there might be a further deterioration in the
quality of their loan portfolios as a result of adverse economic conditions
particularly in Switzerland. These reserves totaled CHF 3.6 billion at the
beginning of 1998. CHF 3.3 billion was applied against specific loan exposures
during 1998 and the balance of CHF 300 million was used or reversed in 1999.
Following these allocations, the credit loss expense incurred in 1998 amounted
to CHF 951 million and in 1999 to CHF 956 million. UBS does not believe there is
a current need for such allowances. See "--Selected Statistical
Information--Summary of Movements in Allowances and Provisions for Credit
Losses" for a further analysis of credit losses.

The allowance and provisions for credit losses include a component for country
risk. UBS's approach to country risk provisioning follows the guidelines of the
Swiss Bankers' Association, which allows banks to establish provisions based on
their own portfolio scenarios. UBS establishes country-specific scenarios, which
are reviewed and used on an ongoing basis to evaluate the current and future
probability of default due to country risk incidents or country-specific
systemic risks. The appropriate allowances and provisions are then determined by
evaluating the type of credit exposure and the loss severities that have been
attributed to each exposure type. Total provisions and allowances for

emerging market-related exposures stood at CHF 1,317 million at 30 June 2000,
CHF 1,376 million at 31 December 1999 and CHF 1,450 million at 31 December 1998,
reflecting both the reduction in the overall size of UBS's emerging market
exposure and reallocation of provisions from Asia to Latin America during 1999.

and Provisions for Credit Losses" and "--Selected Statistical
Information -- Allocation of the Allowances and Provisions for Credit Losses"
for further analyses of the allowances and provisions for credit risk and
related credit losses.

Market Risk.  Market risk is the risk UBS faces as a result of adverse movements
in the value of foreign exchange, commodities, equity market and interest rates
positions. UBS incurs market risk mainly through its trading activities, which
are centered in UBS Warburg, although market risk also arises -- to a
substantially lesser extent -- in relation to other activities, notably in the
context of balance sheet management activities. UBS Warburg's primary market
risk exposure relates to its business activities in equities, fixed income
products and foreign exchange. The risk that UBS Warburg assumes is primarily
related to the need to facilitate its customers' activities in the major OECD
markets.

UBS measures its exposure to market risk using the framework of expected loss,
statistical loss and stress loss, as follows:

- In the context of market risk, expected losses are the value adjustments made
  to the portfolio to adjust for price uncertainties resulting from a lack of
  market liquidity or the absence of a reliable market price for a particular
  instrument.

- One-day loss is measured based on a value at risk, or "VaR," methodology. VaR
  is a forward-looking estimate of potential loss. One-day VaR looks forward one
  trading day, while 10-day VaR looks forward ten days. UBS calculates VaR using
  a 99% confidence level. In other words, under normal market conditions, UBS
  would expect over the course of a day a loss of more than its 1-day VaR to
  occur 1 in 100 times.

- Stress scenario loss is defined as the risk of an extreme market move
  affecting particular predefined market variables.

In order to keep its exposure to market risk within acceptable boundaries, the
UBS Board of Directors has set limits on UBS's exposure to both statistical loss
by reference to the VaR exposures as well as to stress scenario loss by placing
limits in relation to particular stress scenarios.

UBS calculates the VaR associated with its exposure to market risk and
consequently also its regulatory market risk capital requirement using the
historical simulation technique, based on five years of data. VaR is calculated
both on a 1-day 99% confidence interval and a 10-day 99% confidence interval,
and the latter is used both for internal limits setting and for calculating
regulatory market risk capital. The calculation incorporates both the risk from
general market moves, such as moves in foreign exchange rates, equity indices
and market interest rates, as well as the risk from price movements that are
specific to an individual issuer. During 1999 and in the first six months of
2000, UBS Warburg operated within a CHF 450 million 10-day VaR limit.

The Swiss Federal Banking Commission, or "FBC," approved the use of UBS's VaR
model to compute regulatory capital requirements for market risks in 1999.

While a VaR measure is the principal measure of UBS's exposure to day-to-day
movements in market prices, UBS's risk control process is specifically focused
on tail risks (or the risk of a loss on UBS's portfolios significantly larger
than the VaR number as a result of large movements in the risk factors, such as
equity indices, foreign exchange rates and interest rates). UBS has a consistent
set of predefined

large price movements, or shocks, and risk limits, which apply to all the major
risk factors to which UBS is exposed as a basis to prevent risk concentration.
This is the primary protection against any extreme event. In addition to this
first level protection, a stress loss limit has been introduced as a portfolio
control for all the trading activities that are concentrated within UBS Warburg.
The potential stress loss is calculated with respect to eight base scenarios
which are supplemented by ad hoc analyses depending on external developments or
specific portfolio concentrations such as Year 2000, which UBS added to its
stress test analysis in the third quarter of 1999. This ensures that both
historical crises as well as forward-looking extreme scenarios are incorporated
in the analysis. Implementing this stress loss limit is a way of protecting
UBS's earnings during periods of extreme market stress.

UBS Warburg Market Risk Developments.  Market risk exposure as measured by the
10-day 99% confidence VaR was generally higher over 1999 and the first half of
2000. However, utilization remained well within the limits. The main market risk
drivers continued to be Equity and Interest Rate risk.

All VaR models, while forward-looking, are based on past events and are
dependent upon the quality of available market data. In order to evaluate the
VaR model, actual revenues are compared with the 1-day VaR on a daily basis, a
process known as "backtesting," with losses greater than the VaR estimate being
known as "exceptions." As the chart below shows, UBS Warburg's backtesting
results showed no exceptions over the last 12 months. In addition, there were no
exceptions during 1999.

Market Risk in the Other Business Groups.  Although UBS assumes almost all of
its active market risk in UBS Warburg, the Group-wide VaR utilization includes
all sources of market risk. This includes a small amount of risk that is assumed
in order to facilitate customer business by UBS Private Banking in Switzerland
as well as the risk associated with the structural foreign exchange and interest
rate hedge positions managed by Corporate Center, which are discussed below
under "-- Asset and Liability Management." However, market risk exposure at the
UBS group level continues to be dominated by the UBS Warburg positions.

Consequential Risks.  In addition to credit and market risks that UBS assumes as
an integral part of its business activities, UBS also assumes a number of
consequential risks -- often referred to as "operational risk" -- which arise as
a consequence of its business activities. These risks include:

-  operations or transactions processing risk;

-  legal risk;

-  compliance risk;

-  liability risk; and

-  security risk.

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

<PAGE>   137
UBS
--------------------------------------------------------------------------------

UBS is addressing the measurement of its consequential risks through the
introduction of a generic operational risk-modeling framework. This framework
groups risks into predetermined risk categories and identifies the factors
behind the risk exposure. Operational risk scenarios are developed to stress
UBS's processes and procedures underlying the exposure. This helps UBS to
measure the risk of loss from the identified exposure in a similar manner to the
statistical loss measurements of its credit and/or market risk exposures. This
framework is relatively new and is periodically reviewed and enhanced so that
risks are accurately assessed and are in accordance with UBS's risk appetite and
risk-bearing capacity.

Year 2000 Issue.  An important element of UBS's operational risks over the past
two years has been the need to address the Year 2000 issue. UBS recognized early
the potential problems that could arise from computer systems failing to
properly recognize the change of date from 1999 to 2000. To combat this problem,
starting in 1996, UBS and each of its operating divisions established and
implemented a program responsible for addressing the Year 2000 issue.

UBS has not experienced any material problems related to the Year 2000 date
change. The total cost to UBS of the Year 2000 program was CHF 493 million in
1998 and CHF 279 million in 1999.

Asset and Liability Management

UBS's asset and liability management processes are designed to manage all
balance sheet related risks on a coordinated Group-wide basis. The procedures
and policies cover Group liquidity, Group funding and capital management, and
the management of non-trading foreign exchange and interest rate risk.

UBS recognizes that the market and credit risk framework that is set out above
cannot be fully applied to its asset and liability management activities.
Consequently, specific processes and policies have been established for managing
these risks. UBS's asset and liability management function is undertaken at the
Corporate Center by the Group Treasury department, which reports directly to the
CFO. Group Treasury is responsible for establishing and effectively managing the
processes in relation to these risks in accordance with policies that have been
approved by the Board of Directors.

The overriding goals of all processes within the asset and liability management
activities are:

- efficient management of the bank's non-trading interest rate and foreign
  exchange exposures;

- sustainable and cost-efficient funding of the bank's balance sheet;

- optimal liquidity management in order to generate cash when required; and

- compliance with legal and regulatory requirements.

Interest Rate Management.  Interest rate risk is inherent to most of UBS's
businesses. Interest rate risks arise from a variety of factors, including
differences in the timing between the contractual maturity or repricing of
assets, liabilities and derivative instruments. Net interest income is affected
by changes in market interest rates, given that the repricing characteristics of
loans and other interest earning assets do not necessarily match those of
deposits, other borrowings and capital. In the case of floating rate assets and
liabilities, UBS is also exposed to basis risk, which is the difference in
repricing characteristics of two floating rate indices, such as the savings rate
and six-month LIBOR. In addition, certain products have embedded options that
affect their pricing and principal.

UBS adopts a comprehensive Group-wide approach to managing interest rate risk,
and allocates the responsibility for managing this risk to a limited number of
business areas. Under this approach, interest rate risk is clearly segregated
into trading and non-trading risk. All interest rate risks arising from
non-trading business activities are captured at the point of business
origination and transferred either to UBS Warburg's Cash and Collateral Trading
book -- or "CCT" -- or to the Corporate

--------------------------------------------------------------------------------
                                                                             105

UBS
--------------------------------------------------------------------------------

Center's Bank Book through a Group-wide transfer pricing mechanism. The risk is
then managed centrally in accordance with the relevant risk policy.

In the case of transactions with a fixed maturity, the interest rate risk is
transferred from the relevant business area to CCT on a transaction by
transaction basis. This means that products with fixed maturities immediately
become part of the trading book in UBS Warburg and the business locks in an
interest-rate-risk-free margin on such products, thereby relieving them of any
residual interest rate risk. As a result of this process, UBS benefits fully
from the netting potential between its balance sheet and trading products.

In the case of client business, such as savings accounts or current accounts,
which have no contractual maturity date or directly market-linked customer rate,
the interest rate risk is transferred from the business areas by pooled
transactions to the Bank Book. Since these products effectively contain various
embedded options in respect of withdrawal/prepayment and rate-setting, they
cannot be hedged by single back-to-back transactions. Consequently, Group
Treasury manages the inherent interest rate risk in these products in the Bank
Book through the establishment of replicating portfolios of revolving fixed-rate
transactions of predefined maturities, which approximate the average cash flow
behavior of these positions. Group Treasury then hedges the overall risk in the
Bank Book by means of internal transactions with CCT. As a result of this
process, all interest rate risks arising from client business are transferred
either directly or indirectly via the Bank Book to CCT.

In addition to the interest rate risk associated with client business, a
significant amount of interest rate risk arises in relation to non-business
balance sheet items, such as in the refinancing of the bank's real estate
portfolio, equity investments in associated companies and the investment of
UBS's own equity. The refinancing of real estate and equity investments and the
investment of equity are all strategic decisions that implicitly create
non-trading interest rate exposures. The interest rate risks inherent in these
balance sheet items are managed in the Bank Book by representing them as
replicating portfolios, on the basis of decisions taken by the Group Executive
Board as to the appropriate effective maturities. Here, too, the risk is hedged
by means of internal transactions with CCT.

All the replicating portfolios that are contained in the Bank Book are updated
monthly by replacing maturing tranches with new aggregate tranches that reflect
the changes in the balance sheet over the period. By their nature, the staggered
tranches that constitute each replicating portfolio reduce the volume that must
be hedged by the Bank Book at each monthly rollover. However, due to the extent
of the underlying portfolio volumes, the new aggregate tranches are nevertheless
of such a size that they cannot be hedged instantly. The Bank Book therefore
assumes intramonth interest rate exposure until it can execute all the necessary
offsetting hedges with CCT. The exposure of the Bank Book, which thus tends to
fluctuate between monthly rollovers and the profits or losses arising out of the
Bank Book, are reported on an accrual basis in the financial statements and
constitute an integral part of the Group's net interest income.

The Board of Directors has approved risk management policies, risk limits and
the control framework for the entire interest rate risk management process
including the establishment of a VaR limit for the interest rate exposure of the
Bank Book. Market Risk Control monitors the risk in both CCT and in the Bank
Book on a daily basis as part of the Group's overall market risk in order to
ensure the integrity of the interest rate risk management process and UBS's
compliance with the defined risk limits.

UBS's approach to managing the interest rate risks inherent in the Bank Book
complies with the regulatory framework recently introduced by the FBC. In the
course of the year 2000, it will become mandatory for all Swiss banks to report
to the Swiss National Bank the interest rate sensitivity of the Bank Book on a
quarterly basis. Additionally, the specific composition of the underlying
replicating

portfolios used to manage individual balance sheet items must also be disclosed
in order to assist the regulators to identify 'outliers' in terms of their
interest rate risk profiles.

The following table shows the interest rate sensitivity of the Bank Book as at
30 June 2000 measured in terms of the potential impact of a one basis point
(0.01%) parallel rise in interest rates on the market value of each balance
sheet item.

</TABLE>

The most significant component of the Bank Book sensitivity stems from the
investment of UBS's equity. At 30 June 2000, this was invested in a portfolio of
fixed-rate CHF deposits with an average duration of 2.5 years and a sensitivity
of CHF (9.0) million per basis point, in line with the strategic investment
targets set by the Group Executive Board. In order to ensure that these Group
Executive Board targets are met, UBS's equity is represented as a liability
position by a replication portfolio reflecting this target benchmark. UBS's
equity becomes then automatically invested according to the Group Executive
Board's strategic targets so as to offset the interest rate risk associated with
this equity replication portfolio. The interest rate sensitivity of these
investments indicates the extent to which their marked-to-market value would be
affected by an upward move in interest rates. This in turn is directly related
to the investment duration chosen by the Group Executive Board. However, when
measured against the equity replication portfolio itself, the residual interest
rate risk is negligible. Moreover, any reduction in this measure of the interest
rate sensitivity relating to the investment of UBS's equity would inevitably
require investing at significantly shorter maturities, which would lead to a
higher volatility of UBS's interest earnings.

In addition to the above standard sensitivity to a one basis point rise in
rates, UBS uses the following two measures to help to monitor the risk inherent
in the Bank Book:

-  Net interest income at risk, which is defined as the exposure of the net
   interest income arising in the Bank Book to an adverse movement in interest
   rates over the next twelve months. Given the fact that all client business
   with fixed maturities is "match funded" with UBS Warburg, these transactions
   are not affected by changes in interest rates. Therefore only net interest
   income positions resulting from replicating portfolios may be exposed to
   market changes. This measure estimates the impact of different changes in the
   level of interest rates using shock scenarios as well as gradual changes in
   interest rates over a period of time. All of the scenarios are compared with
   a scenario in which current market rates are held constant for the next
   twelve months.

                                                                             107
<PAGE>   140
UBS
--------------------------------------------------------------------------------

-  The economic value sensitivity, which is defined as the potential change in
   market value of the Bank Book resulting from changes in interest rates. This
   estimates the effect of an immediate interest rate shock on the net position
   in the Bank Book.

The net interest income at risk measure on the Bank Book considers such
variables as:

-  repricing characteristics of assets and liabilities;

-  rate barrier effects, such as caps and floors, on assets and liabilities;

-  maturity effects of replicating portfolios; and

-  behavior of competitors.

Both measures are based on the Bank Book's interest rate position excluding the
liability position relating to the "equity replication portfolio." The
methodology is designed to highlight the effects of market changes in interest
rates on existing balance sheet positions; it ignores future changes in the
asset and liability mix and therefore it is not by itself a measure of future
net interest income.

The two methodologies provide different measures of the level of interest rate
risk. The economic value sensitivity measure provides a longer term view, since
this considers the present value of all future cash flows generated from the
existing balance sheet positions. The net interest income at risk measure
provides a shorter term view, as it considers the repricing effect of all
maturing positions over the next twelve months. The table below shows the change
in risk under both measures at 30 June 2000, 31 December 1999 and 1998.

</TABLE>

Among various scenarios that have been analyzed the net interest income at risk
figure shown is the worst case and relates to an interest rate shock (parallel
shift) of -200 basis points. At 31 December 1998, the difference to the constant
market rate scenario represents -4.07% of UBS's 1998 total net interest income,
-5.6% at 31 December 1999 and -3.0% at 30 June 2000. In this extreme scenario
the largest part of the decrease would occur due to lower margins on deposit
accounts and lower returns on the investment of UBS's equity.

The economic value sensitivity shows the effect of a 100 basis point adverse
interest rate shock, implying that the bank had an exposure of CHF (493) million
to rising interest rates at 31 December 1998, CHF (555) million at 31 December
1999 and CHF (787) million at 30 June 2000.

Liquidity and Funding Management.  UBS's approach to liquidity management seeks
to ensure that UBS will always have sufficient liquidity to meet its liabilities
in a timely manner while preserving the option of exploiting potential strategic
market opportunities. UBS's centralized approach to liquidity management
encompasses the entire network of branches and all subsidiaries and ensures that
the liquidity position is more than adequate to cover short-term liabilities at
all times. UBS's liquidity management is based on an integrated framework that
incorporates an assessment of all known cash flows within UBS as well as the
availability of high grade collateral that could be used to secure additional
funding if required. The liquidity position is prudently managed under different
potential scenarios taking stress factors into due consideration.

UBS's Board of Directors has approved a policy that establishes the core
principles for liquidity management and has defined an appropriate contingency
plan. A first set of principles relates to the establishment of liquidity risk
limits, such as a net overnight funding limit. The risk limits are set by

--------------------------------------------------------------------------------
 108
<PAGE>   141
UBS
--------------------------------------------------------------------------------

the Group Executive Board and monitored by the Group Treasury Committee, or
"GTC," which is chaired by the Group Treasurer and meets on a monthly basis in
order to assess the bank's liquidity exposure. A second set of principles
concentrates on liquidity crisis management for which detailed contingency plans
have been worked out. Regional committees constantly monitor the markets in
which UBS operates for potential threats and regularly report their findings to
the GTC. If a liquidity crisis occurs, regional crisis task forces will perform
all necessary contingency actions under the command of senior management.

The liquidity management process is undertaken jointly by Group Treasury and
CCT. Group Treasury's function is to establish a comprehensive framework of
directives and risk limits, while CCT undertakes the operational cash and
collateral management transactions within the established parameters. UBS's
centralized cash and collateral business management structure facilitates a
tight control on both the global cash position and the stock of highly liquid
and rediscountable securities.

UBS's funding strategy seeks to ensure that business activities are funded at
the lowest possible costs. With a broad diversification (by market, product and
currency) of funding sources UBS maintains a well balanced portfolio of
liabilities which generate a stable flow of financing and additionally provides
protection in the event of market disruptions. In this context UBS's strong
domestic retail business is a very valuable, cost efficient and reliable source
of funding. Through the establishment of short-, medium- and long-term funding
programs in Europe, in the US and in Asia, UBS can raise funds globally in a
very efficient manner and minimize its dependence on any particular source of
funding.

See "--Liquidity and Capital Resources" for additional information.

Currency Management.  UBS's corporate currency management activities are
designed to protect UBS's equity and the expected future foreign currency
cash-flows from adverse currency movements against the Swiss franc while
preserving the option of exploiting any market opportunities which may arise.

The following principles guide the approach to managing this risk:

-  UBS's equity must be invested in Swiss francs (translation risk management);
   and

-  Recognized foreign currency exposures must be hedged proactively for the
   whole financial year, which represents the cycle of financial accounting
   (transaction risk management).

Translation (Balance Sheet) Currency Risk.  UBS aims to maintain the flexibility
to allow foreign assets (a business unit or a non-financial asset) to be
divested at any time without adverse currency impacts. To limit these undesired
foreign exchange impacts on investments and divestments of these assets, foreign
currency assets are match funded in the relevant currency. The match-funding
principle is also applied to the financing of foreign investments, including
foreign equity investments. This strategy, together with the repatriation into
Swiss francs of foreign currency dividends and capital, ensures that UBS's
equity is always fully invested in Swiss francs.

Transaction (Revenues/Costs) Currency Risk.  UBS's transaction risk currency
management process is designed to protect the budgeted annual foreign currency
net profits against adverse currency movements during the relevant reporting
period. Foreign currency net profits are actively managed by Group Treasury on
behalf of UBS in accordance with the instructions of the Group Executive Board
and subject to the VaR limit that has been established for this risk. The
budgeted net profits are treated as long forward foreign exchange exposures in
the local reporting currency against the Swiss franc.

The non-trading foreign currency exposures are hedged mainly with foreign
exchange forward contracts, although foreign exchange options are also used
particularly where there is a measure of uncertainty about the magnitude of the
underlying income. The net position of the budgeted net profits and the
corresponding hedges is the basis for the VaR calculation on Group Treasury's
non-trading

UBS

currency position. During the year, actual results are continuously monitored.
Major budget deviations must be communicated to Group Treasury for potential
additional hedge transactions. The VaR analysis, which is performed daily, is
based on the same 10-day 99% confidence level as applies in UBS Warburg. The
validity of the VaR measurement is evaluated by conducting backtests, which
compare the estimated VaR amount with the actual shift of the positions' profit
or loss due to exchange rate movements.

The following table summarizes the VaR usage during the second half of 1998,
1999 and the first half of 2000.

The principal contributors to UBS's non-trading currency exposure are the
operations in the UK and the US. In general, the VaR position is highest at the
beginning of the year when the budgeted net profits are transferred to Group
Treasury and is gradually reduced during the year depending on the exact hedge
strategy being used. The underlying policy is to keep the VaR of the non-trading
currency position as low as practicable.

Capital Management.  Capital management is undertaken at UBS by Group Treasury
as an integral asset and liability management function. UBS's overall capital
needs are continually reviewed to ensure that its capital base can appropriately
support the anticipated needs of the divisions as well as regulatory capital
requirements. See "--Liquidity and Capital Resources--Capital Resources" for
further details.

Performance Measurement.  UBS is in the process of implementing a comprehensive
value based management approach intended to support management in key tasks like
planning, investments, capital allocation, performance appraisal and
compensation, strategic risk management and communication to investors and
analysts.

Divisional business plans, planned acquisitions, investments and divestments are
evaluated and approved on the basis of their expected contribution to
shareholder value. Actual performance is appraised using division specific
hurdle rates and according to the contribution to value creation. The implicit
costs of risk tolerance as well as the consumption of regulatory equity and risk
control efforts are therefore considered in an appropriate way.

     Selected Statistical Information

The tables below set forth selected statistical information regarding UBS's
banking operations. Unless otherwise indicated, average balances for the year
ended 31 December 1999 are calculated from monthly data and averages for the
years ended 31 December 1998 and 1997 are calculated from quarterly data. The
distinction between domestic and foreign generally is based on the domicile of
the booking location. For loans, this method is not significantly different from
an analysis based on domicile of the borrower. Disclosures for the years ended
31 December 1996 and 1995, where applicable, are presented for Union Bank of
Switzerland and Swiss Bank Corporation individually. Combined data is not
presented for these periods because differences between accounting policies of
the predecessor banks were significant or could not be quantified, or because
significant inter-company balances could not be identified and eliminated. For
purposes of this selected statistical information, "UBS" refers to Union Bank of
Switzerland and "SBC" refers to Swiss Bank Corporation.

All assets and liabilities are translated into Swiss francs at uniform month-end
rates. Income and expenses are translated at monthly average rates.

Average rates earned and paid on assets and liabilities can change from period
to period based on the changes in interest rates in general, but also are
affected by changes in the currency mix included in the assets and liabilities.
This is especially true for foreign assets and liabilities. Tax exempt income is
not recorded on a tax-equivalent basis. For all three years presented, it is
considered to be insignificant and therefore the impact from such income is
negligible.

Interest income and expense on certain accounts are reported as trading income
in UBS's 1997 consolidated financial statements, but are reported against those
accounts in the table. These accounts include: money market paper, securities
borrowed and lent, reverse repurchase and repurchase agreements, and trading
assets and liabilities. Also, the interest expense in UBS's 1997 consolidated
financial statements is reduced by an amount for funding costs for trading
positions, which is not

Analysis of Changes in Interest Income and Expense.  The following tables
allocate, by categories of interest-earning assets and interest-bearing
liabilities, the changes in interest income and expense due to changes in volume
and interest rates for the year ended 31 December 1999 compared to the year
ended 31 December 1998, and for the year ended 31 December 1998 compared to the
year ended 31 December 1997. Volume and rate variances have been calculated on
movements in average balances and changes in interest rates. Changes due to a
combination of volume and rate have been allocated proportionally.

Loans.  UBS's loans are widely dispersed over customer categories both within
and outside of Switzerland. No one concentration of loans, with the exceptions
of private households in Switzerland and foreign commercial and manufacturing,
accounted for more than 10% of the total loan portfolio. For further discussion
of UBS's loan portfolio, see "--Analysis of Risks--Credit Risk." The following
table illustrates the diversification of the loan portfolio among customer
categories at 31 December 1999, 1998, 1997, 1996 and 1995. The industry
categories presented are consistent with the classification of loans for
reporting to the Swiss Federal Banking Commission and Swiss National Bank.

Impaired, Non-Performing and Restructured Loans.  UBS classifies a loan as
impaired when it is determined that there is a high probability that the bank
will suffer a partial or full loss. A provision is then made with respect to the
probable loss to be incurred for the loan in question. Within the category are
non-performing loans, for which the contractual payments of principal and/or
interest are in arrears for 90 days or more. After the 90-day period, UBS no
longer recognizes interest income on the loan and takes a charge for the unpaid
and accrued interest receivable. Unrecognized interest related to non-performing
loans amounted to CHF 409 million, CHF 423 million and CHF 450 million for the
years ended 31 December 1999, 1998 and 1997, respectively. The table below
provides an analysis of the Group's non-performing and restructured loans at 31
December 1999, 1998, 1997, 1996 and 1995. For further discussion of impaired and
non-performing loans, see "--Analysis of Risks--Credit Risk."

---------------
(1) Amounts presented for 1999 and 1998 include only performing foreign
    restructured loans. Amounts presented for prior years include both
    performing and non-performing foreign restructured loans. UBS does not, as a
    matter of policy, typically restructure loans to accrue interest at rates
    different from the original contractual terms or reduce the principal amount
    of loans. Instead, specific loan allowances are established as necessary.
    Unrecognized interest related to the foreign restructured loans was not
    material to the results of operations during these periods.

In addition to the data above analyzing non-performing loans, at 31 December
1999 UBS had CHF 9,383 million in "other impaired loans." These are loans that
are current, or less than 90 days in arrears, with respect to payment of
principal or interest; however, UBS's credit officers have expressed doubts as
to the ability of the borrowers to repay the loans, and specific allowances of
CHF 3,810 million have been established against them. These loans are primarily
domestic.

Cross-Border Outstandings.  Cross-border outstandings consist of general banking
products such as loans and deposits with third parties, credit equivalents of
over-the-counter derivatives and repurchase agreements, and the market value of
the inventory of securities. The outstandings are monitored and reported on an
ongoing basis by the credit risk management organization with a dedicated
country risk information system. With the exception of the 27 most developed
economies, the exposures are rigorously limited.

Claims that are secured by third-party guarantees are recorded against the
guarantor's country of domicile. Outstandings that are secured by collateral are
recorded against the country where the asset could be liquidated. This follows
the "Guidelines for the Management of Country Risk," which are applicable to all
banks that report to the Swiss Federal Banking Commission as their supervisory
body.

The following tables list those countries for which UBS's cross-border
outstandings exceeded 0.75% of total assets at 31 December 1999, 1998 and 1997.
At 31 December 1999, there were no outstandings that exceeded 0.75% of total
assets in any country currently facing liquidity problems that the bank expects
would materially affect the country's ability to service its obligations.

For more information on cross-border outstandings, see "--Analysis of
Risks--Credit Risk--Country Risk Exposure."

Summary of Movements in Allowances and Provisions for Credit Losses.  The
following table provides an analysis of movements in allowances and provisions
for credit losses for the years ended 31 December 1999, 1998, 1997, 1996 and
1995.

As a result of Swiss bankruptcy laws, banks write off loans against allowances
only upon final settlement of bankruptcy proceedings, the sale of the underlying
asset and/or in case of the forgiveness of debt. Under Swiss law, a creditor can
continue to collect from a debtor who has emerged from bankruptcy, unless the
debt has been forgiven through a formal agreement.

    The 1995 UBS and SBC amounts represent provisions for general banking risks
    and commitments and contingent liabilities, respectively.

The following table presents the percentage of loans in each category to total
loans at 31 December 1999, 1998, 1997, 1996 and 1995. This table can be read in
conjunction with the preceding table showing the breakdown of the allowances and
provisions for credit losses by loan categories to evaluate the credit risks in
each of the categories.

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The accompanying unaudited pro forma financial statements on pages 127 to 150
present the condensed consolidated balance sheet of UBS and PaineWebber as of 30
June 2000 and the related condensed consolidated income statements for the
six-month period ended 30 June 2000 and the year ended 31 December 1999, as if
the merger had occurred on 1 January 1999. The presentation is made both on the
basis of IAS and U.S. GAAP. In order to present this information and show the
reader the source of the information, several schedules are required.

The first set of schedules included present the unaudited pro forma financial
statements on the basis of IAS, in Swiss francs (CHF). This is achieved by
presenting in the first two columns the financial statements of PaineWebber in
accordance with IAS in U.S. Dollars (USD), and then showing the translation into
CHF. The third column presents the IAS financial statements of UBS in CHF. We
then present accounting entries to reflect the results of the merger, each of
which is explained in a footnote, and the final resulting column presents the
unaudited pro forma condensed consolidated financial statements. Since IAS will
be the primary accounting framework of the consolidated company, we present this
information first.

PaineWebber presents its financial statements on the basis of U.S. GAAP rather
than IAS. The second set of schedules shows the restatement of the U.S. GAAP
financial statements of PaineWebber into IAS. The first column presents the U.S.
GAAP financial statements of PaineWebber, after reflecting certain
reclassification entries required to conform to the UBS presentation. These
reclassification entries do not affect net income or shareholders' equity, and
are therefore not presented separately in this document. The next column
presents the accounting entries required to restate the financial statements on
the basis of IAS, and each entry is explained in a footnote. The final resulting
column presents the PaineWebber financial statements in accordance with IAS, and
is the same as the first column in the first set of schedules described in the
preceding paragraph.

The third set of schedules presents the unaudited pro forma condensed
consolidated financial statements in accordance with U.S. GAAP. In much the same
way that UBS is required to present a reconciliation of its primary financial
statements from IAS to U.S. GAAP, we have also presented this reconciliation.
The first column presents the IAS unaudited pro forma condensed consolidated
financial statements and is the same as the next to last column in the first set
of schedules described two paragraphs above. The next two columns present the
accounting entries required to restate the unaudited pro forma financial
statements for UBS and PaineWebber, respectively, in accordance with U.S. GAAP.
Each of the entries is described in a footnote. The final column presents the
unaudited pro forma condensed consolidated financial statements in accordance
with U.S. GAAP.

THE UNAUDITED PRO FORMA FINANCIAL STATEMENTS WERE PREPARED DURING AUGUST 2000,
SHORTLY AFTER THE MERGER WAS ANNOUNCED, AND THEY HAVE NOT BEEN UPDATED SINCE
THEN.  As of the date of this prospectus, the analyses necessary to complete the
purchase accounting entries required to reflect the merger have not been
finalized. However, several of the assumptions and data inputs used in preparing
the pro forma financial statements have changed. The more significant changes
include:

- Price of UBS Stock. UBS stock was assumed to be valued at $148.75 (CHF245.70)
  per share for purposes of computing the fair value of the stock consideration
  given in the merger. The actual closing price on 3 November 2000 (the date the
  merger was consummated) was $143.30 (CHF252.5) per share.

- Employee stock options. The pro forma financial statements assume that all
  outstanding PaineWebber employee stock options would have been exercised prior
  to consummation of the merger. In fact, a significant number of options were
  exchanged for options on UBS stock rather than being exercised.

--------------------------------------------------------------------------------
                                                                             125
<PAGE>   158
UBS
--------------------------------------------------------------------------------

- UBS partial dividend. The partial dividend authorized by UBS shareholders in
  their Extraordinary General Meeting has not been reflected in the pro forma
  financial statements.

- Fair value of PaineWebber debt. At the time the merger was announced,
  PaineWebber debt instruments were being traded generally at a discount to face
  value. Since that time, the market for these instruments has changed
  reflecting the prospective guarantee announced by UBS and they are now valued
  at a premium to face value.

- Final identification of all acquisitions related liabilities has not been
  completed.

- Analyses necessary to conform PaineWebber accounting policies to those of UBS
  and to adjust other PaineWebber assets and liabilities to fair value in
  accordance with purchase accounting have not yet been completed.

All of these matters will result in changes to the estimates included in the
accompanying pro forma financial information, which will, in the aggregate be
significant. While we do not expect the changes to result in any material change
to operating income as presented in the pro formas, these changes will increase
the recorded balance of goodwill significantly, as well as the related annual
amortization.

         UBS AND PAINEWEBBER UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                       BALANCE SHEET AND INCOME STATEMENT
                AS OF AND FOR THE SIX MONTHS ENDED 30 JUNE 2000

The following unaudited pro forma condensed consolidated balance sheet and
income statement as of and for the six months ended 30 June 2000 is derived from
the unaudited consolidated financial statements of UBS as of and for the six
month period then ended and PaineWebber's unaudited condensed consolidated
financial statements as of and for the same period, as adjusted to IAS and
translated into Swiss francs, after giving effect to the pro forma adjustments
described in the notes to the UBS and PaineWebber unaudited pro forma condensed
consolidated balance sheet and income statement below. These adjustments have
been made as if the merger took place on 1 January 1999, the first day of the
earliest period presented in the UBS and PaineWebber unaudited pro forma
condensed consolidated financial information. This information has been prepared
from, and should be read together with, the respective unaudited consolidated
financial statements and related notes of UBS and the unaudited condensed
consolidated financial statements of PaineWebber, which are included in this
document. These statements have been prepared in accordance with IAS.

        NOTES TO THE UBS AND PAINE WEBBER UNAUDITED PRO FORMA CONDENSED
                CONSOLIDATED BALANCE SHEET AND INCOME STATEMENT

   AS OF AND FOR THE SIX MONTHS ENDED 30 JUNE 2000 AND FOR THE YEAR ENDED 31
                                 DECEMBER 1999

1. TRANSLATION OF PAINEWEBBER FINANCIAL STATEMENTS

PaineWebber presents its financial statements on a U.S. GAAP basis and in U.S.
dollars. These financial statements have been restated into IAS. The restated
income statement of PaineWebber has been translated into Swiss francs at the
average rate of CHF 1.66 per U.S. $1.00 for the six months ended 30 June 2000
and CHF 1.50 per U.S. $1.00 for the year ended 31 December 1999.

The restated PaineWebber balance sheet has been translated into Swiss francs at
the spot rate of CHF 1.63 per U.S. $1.00 at 30 June 2000 and CHF 1.59 per U.S.
$1.00 at 31 December 1999.

These translations should not be taken as assurances that the CHF amounts
currently represent U.S. dollar amounts or could be converted into U.S. dollars
at the rate indicated or at any other rate, at any time.

2. PRO FORMA ACQUISITION ADJUSTMENTS

The unaudited pro forma condensed consolidated financial information records the
merger as being accounted for as an acquisition with the excess of the fair
value of the consideration over the fair value of net assets acquired being
allocated to goodwill. See the discussion below for information related to
recording the issuance of UBS ordinary shares, trust preferred securities and
debt to effect the purchase, the related retirement of shares of PaineWebber
common stock, the adjustment of PaineWebber's assets and liabilities to fair
value, and the recording of the resulting goodwill.

  Issuance of UBS Securities and the Retirement of PaineWebber Securities

The unaudited pro forma condensed consolidated financial information assumes a
total purchase price of $12,696 million (CHF 20,970 million). Pursuant to the
terms of the merger agreement, UBS will issue approximately 42.7 million UBS
ordinary shares, equivalent to $6,348 million (CHF 10,485 million), and pay
$6,348 million (CHF 10,485 million) in cash in exchange for 172.8 million shares
of PaineWebber common stock at an exchange ratio of 0.4954. The total purchase
price assumed is based on the closing price of UBS ordinary shares on the New
York Stock Exchange on 11 July 2000, which was $148.75 (CHF 245.70). Additional
costs relevant to the merger include estimated professional fees of $90 million
(CHF 149 million) (primarily legal, investment bankers' and accountants' fees)
to be accounted for as acquisition costs.

For purposes of determining the number of PaineWebber shares to be canceled, it
is assumed that, in addition to the 146.8 million shares outstanding as of 11
July 2000, PaineWebber employee stock options and convertible debt representing
approximately 33.6 million shares will be exercised or converted at an aggregate
strike price of $908 million (CHF 1,500 million), at a range of $6.69 to $48.56,
or CHF 11.05 to CHF 80.21, per share, and reduced by approximately 7.6 million
shares of PaineWebber common stock that may be repurchased from employees at
$73.50 (CHF 121.42) per share for a total price of $562 million (CHF 928
million) to satisfy their individual tax withholding requirements.

a. This entry records the cash consideration of $6,348 million (CHF 10,485
million) to be paid in the merger, on the basis of the assumptions noted in this
footnote. We have assumed, for purposes of these pro forma financial statements,
that UBS will issue, directly or indirectly through subsidiaries, $1,500 million
(CHF 2,478 million) in trust preferred securities during the third and fourth
quarters of 2000. Although it has not yet been determined how the proceeds of
these trust preferred securities will be applied by UBS, we have assumed, solely
for the purposes of these pro forma financial statements, that the cash
consideration in the merger will be financed from the proceeds of those trust
preferred securities and through the issuance of short-term debt instruments.
UBS will also enter into certain interest rate swap transactions in order to
produce the effect of issuing medium- to long-term debt.

     Fair Value and Book Value Adjustments

b. This entry records the adjustments to state the net assets of PaineWebber at
their fair market values and additional book value adjustments as of 30 June
2000. A preliminary allocation of the purchase price has been performed for
purposes of the unaudited pro forma condensed consolidated financial information
based on initial appraisal estimates and other valuation studies which are in
process and on certain assumptions that UBS believes are reasonable. The final
allocation is subject to completion of these studies, which is expected to be
within the next twelve months. However, UBS does not expect the differences
between the preliminary and final allocations to have a material impact on
shareholders' equity or net profit for the periods. A summary, in accordance
with IAS, is shown on the following page.

Certain financial and non-financial assets, long-term debt and corresponding
hedging derivatives, and pension obligations have been adjusted to reflect their
estimated fair values. All remaining assets and liabilities are reported in the
historical accounts at approximately their respective fair values. The fair
value adjustments have been shown pre-tax, with an aggregate tax effect, based
on a 35% effective tax rate, disclosed.

PaineWebber vested and non-vested options and convertible debt outstanding as of
11 July 2000 are assumed to be fully exercised or converted prior to the merger.
The resulting proceeds, related tax benefit and redemption of shares of
PaineWebber common stock in satisfaction of employees' tax withholding
requirements have been reflected in the adjustments.

The purchase consideration and pro forma adjustments shown above are based in
part on the assumption that all of the 33.6 million PaineWebber employee stock
options and convertible debt are exercised/converted and the resulting shares
(net of shares repurchased by PaineWebber) are tendered as part of the share
exchange. UBS stock options will be issued to replace PaineWebber options and
convertible debt that are not exercised/converted. If none of the PaineWebber
stock options/convertible debt were exercised/converted, 16.7 million UBS
options would be issued, with a fair value of $1,845

d. This entry records the amortization of goodwill of $221 million (CHF 364
million) in the six months ended 30 June 2000, and $441 million (CHF 729
million) in the year ended 31 December 1999.

  Other Merger-Related Adjustments

e. This entry records interest expense accrued on $4,677 million (CHF 7,724
million) of merger-related short-term debt. The interest expense assumes a
weighted average rate of 6.85% on the short-term debt and a 0.50% rate on swaps
used to hedge the short-term debt, for a total interest rate of 7.35%. The
resulting adjustment to interest expense is $172 million (CHF 285 million) for
the six months ended 30 June 2000, and $344 million (CHF 517 million) for the
year ended 31 December 1999. The effect of a 1/8% increase in interest rates
would be to increase interest expense by $3 million (CHF 5 million) for the six
months ended 30 June 2000 and by $6 million (CHF 9 million) for the year ended
31 December 1999.

f. This entry records the distributions accrued on $1,500 million (CHF 2,478
million) of trust preferred securities issued, assuming a distribution rate of
9%. The distributions accrued are $68 million (CHF 111 million) for the six
months ended 30 June 2000, and $135 million (CHF 223 million) for the year ended
31 December 1999. The effect of a 1/8% increase in rates would be to increase
distributions by $1 million (CHF 2 million) for the six months ended 30 June
2000 and by $2 million (CHF 3 million) for the year ended 31 December 1999.

g. This entry records amortization of net discount resulting from fair market
valuation of PaineWebber long-term debt and associated hedging swaps. The
amortization period is a straight line period of 5 years (the average maturity
of the long-term debt). The amounts amortized are $9 million (CHF 14 million)
for the six months ended 30 June 2000 and $17 million (CHF 28 million) for the
year ended 31 December 1999.

        NOTES TO THE UBS AND PAINE WEBBER UNAUDITED PRO FORMA CONDENSED
         CONSOLIDATED BALANCE SHEET AND INCOME STATEMENT -- (CONTINUED)

h. This entry records the establishment of an employee retention bonus program.
For purposes of this pro forma presentation, it is assumed that approximately 5
million restricted UBS ordinary shares, 2 million UBS stock options and $37.5
million (CHF 62 million) cash, with an aggregate value of $875 million (CHF
1,446 million), subject to vesting restrictions of 2 to 4 years, will be awarded
to certain employees of PaineWebber. It is further assumed that the options will
be issued with strike prices equivalent to the current market value of UBS
ordinary shares. No compensation expense is recorded for the options. The
assumed issuance of restricted UBS ordinary shares results in incremental
compensation expense of $94 million (CHF 156 million) for the six months ended
30 June 2000 and $188 million (CHF 310 million) for the year ended 31 December
1999. The related deferred compensation expense at the end of such periods is
$470 million (CHF 776 million) and $564 million (CHF 931 million), respectively.
The cash component of the award results in compensation expense of $6 million
(CHF 10 million) for the six months ended 30 June 2000 and $13 million (CHF 21
million) for the year ended 31 December 1999. For purposes of computing the cash
requirements in a. above, initial funding of the cash awards includes the total
amount expensed through the periods ending 30 June 2000, $19 million (CHF 31
million).

i. This entry records PaineWebber's recognition of $908 million (CHF 1,500
million) in proceeds from the exercise of existing PaineWebber employee stock
options as a reduction in short term borrowings used to fund the merger.

j. This entry records the payment of $66 million (CHF 109 million) in Swiss
assessments required upon the issuance of new UBS ordinary shares in the merger.
For purposes of this entry, we have assumed the entire stock component of the
purchase consideration will be newly issued shares. The actual amount of newly
issued shares may differ if UBS issues shares from treasury stock or enters into
stock borrow transactions as a funding source.

k. This entry records the amortization of the fair market valuation of lease
obligations. The amortization period is a straight line period of 14 years (the
average economic life of existing lease obligations, to be fair valued). The
amortization expense is $5 million (CHF 8 million) for the six months ended 30
June 2000 and $10 million (CHF 17 million) for 31 December 1999.

l. This entry records the tax effects of the relevant pro forma adjustments
arising from the acquisition at the assumed effective rate of 35%, for both
balance sheet and income statement purposes, resulting in a net tax benefit of
$102 million (CHF 169 million) for the six months ended 30 June 2000 and $203
million (CHF 306 million) for the year ended 31 December 1999.

3. CONVENIENCE TRANSLATION

30 June 2000 and 31 December 1999 CHF amounts have been translated into U.S.
dollars at the exchange rate of one US$=CHF 1.63, the exchange rate on 30 June
2000.

4. PAINEWEBBER EARNINGS PER SHARE

The EPS amounts presented for PaineWebber reflect pro forma IAS adjustments to
income and effects of currency translation and will thus differ from those
presented in PaineWebber's historical audited and unaudited consolidated
financial statements.

5. PROPOSED DIVIDEND

At the extraordinary general meeting of UBS AG, held on 7 September 2000, the
UBS shareholders approved the UBS Board of Directors proposal that a partial
dividend be paid to UBS shareholders on record as of 2 October 2000. The
payment, which was made on 5 October 2000, relates to the first nine months of
the year 2000. The payment of $2.75 (CHF 4.50) per share amounted to
approximately $1.1 billion (CHF 1.8 billion). This dividend has not been
reflected in the assumptions made for purposes of presenting pro forma financial
information.

             NOTES TO THE PAINEWEBBER UNAUDITED PRO FORMA CONDENSED
       CONSOLIDATED STATEMENT OF FINANCIAL CONDITION AND INCOME STATEMENT
                        CONVERSION FROM U.S. GAAP TO IAS
              AS OF AND FOR THE SIX MONTHS ENDED 30 JUNE 2000 AND
                        THE YEAR ENDED 31 DECEMBER 1999

1. RECLASSIFICATION TO CONFORM PAINEWEBBER ACCOUNTS WITH UBS FINANCIAL
PRESENTATION

Reclassifications have been made to the PaineWebber historical financial
information presented under U.S. GAAP to conform to UBS's presentation under
IAS.

The principal income statement reclassifications relate to:

 1. Commission revenue, Asset management revenue, and Investment banking revenue
    have been reclassified as Net fees and commission revenue.

 2. Compensation and benefits expense has been reclassified into the Personnel
    balance.

 3. Office and equipment expense, Communication expense, Business development
    expense, Professional services expense, and Other expenses have been
    reclassified into the General and administrative and Depreciation and
    Amortization expense balances.

The principal balance sheet reclassifications relate to:

 1. Cash and cash equivalents, Cash and securities segregated and on deposit for
    federal and other regulations, and Receivables from broker dealers have been
    reclassified into Due from banks.

 2. Treasury bills and money market securities have been removed from Financial
    instruments owned and moved into Money market paper.

 3. Positive and negative replacement values on derivatives have been separated
    from Financial instruments owned or sold, not yet purchased into their own
    respective line items.

 4. Receivables from clients have been reclassified to Loans, net of allowances
    for credit losses.

 5. Dividend and interest receivables and Fees and other receivables have been
    reclassified into Accrued income and prepaid expenses.

 6. Intangible assets and goodwill have been removed from Other assets and
    classified into their own line item.

 7. Commercial and money market paper issued by PaineWebber have been removed
    from Short term borrowings and reclassified into Money market paper issued.

 8. Short term borrowings, excluding those removed above, and Payables to broker

None of these reclassification adjustments has an impact on net income or
shareholders' equity.

2. U.S. GAAP TO IAS ADJUSTMENTS

Accounting principles generally accepted in the United States differ in material
respects from IAS. The differences that are material to restating the historical
consolidated financial statements of PaineWebber to comply with IAS are
described below.

--------------------------------------------------------------------------------
                                                                             139

             NOTES TO THE PAINEWEBBER UNAUDITED PRO FORMA CONDENSED
       CONSOLIDATED STATEMENT OF FINANCIAL CONDITION AND INCOME STATEMENT
                CONVERSION FROM U.S. GAAP TO IAS -- (CONTINUED)

  Adjustments to Historical PaineWebber Financial Statements:

     a. Software Capitalization

IAS 38, Intangible Assets, became effective 1 January 2000 for entities
reporting on a calendar year basis. This standard requires that companies
capitalize certain costs of acquiring or developing internal use software. Prior
to 1 January 2000, these costs were expensed. Under U.S. GAAP, PaineWebber early
adopted SOP 98-1, Accounting for the Costs of Software Developed or Obtained for
Internal Use, and capitalized such costs beginning in 1998. For purposes of the
pro forma presentation, the effects of capitalization and related amortization
prior to 1 January 2000 are reversed and costs are instead recognized in expense
as incurred.

     b. Hedge Accounting

Under U.S. GAAP, unrealized gains and losses on derivatives that qualify for
hedge accounting are not recognized on the face of the balance sheet. Under IAS,
the replacement value of all derivative products, including those qualifying for
hedge accounting, are recognized on the balance sheet. For purposes of the pro
forma presentation, positive and negative replacement values for derivatives
qualifying for hedge accounting are reported on the face of the balance sheet,
with the net offset reported as other assets.

     c. Repurchase, Resale, and Securities Lending Transactions

Under IAS, repurchase agreements and securities borrowed are accounted for as
collateralized borrowings. Reverse repurchase agreements and securities lending
are accounted for as collateralized lending transactions. Cash collateral is
reported on the balance sheet at amounts equal to the collateral advanced or
received.

Under U.S. GAAP, securities lending and repurchase transactions are also
generally accounted for as collateralized borrowing and lending transactions.
However, certain such transactions may be deemed sale or purchase transactions
under specific circumstances. The accounting for these transactions has been
reversed for purposes of the IAS presentation.

Additionally, under U.S. GAAP, when specific control conditions exist,
securities collateral controlled is recognized as an asset with an offsetting
obligation to return such securities collateral. For purposes of IAS
presentation, such controlled securities collateral has been de-recognized.

     d. Goodwill and Other Intangibles

Under IAS, amortization of goodwill and other intangible assets is generally
limited to a maximum period of 20 years. U.S. GAAP provides that goodwill and
other intangibles are amortizable over their useful economic life with a maximum
life of 40 years. For purposes of the pro forma presentation, the amortization
of PaineWebber's goodwill and other intangibles has been restated using the
maximum 20 year period.

     e. Trade Date v. Settlement Date

UBS follows a settlement date convention of accounting for inventory in its
trading portfolio, for balance sheet presentation purposes. PaineWebber
recognizes purchases and sales of inventory on its statement of financial
condition at their trade date. For purpose of pro forma presentation
PaineWebber's statement of financial condition has been restated as if it
followed settlement date accounting.

       CONSOLIDATED STATEMENT OF FINANCIAL CONDITION AND INCOME STATEMENT
                CONVERSION FROM U.S. GAAP TO IAS -- (CONTINUED)

     f. Rabbi Trusts

PaineWebber has transferred certain compensation related assets into "Rabbi
Trusts." U.S. GAAP requires consolidation of the assets and liabilities of a
Rabbi Trust. IAS, however, applies a "controls" approach in determining whether
an entity should be consolidated. Under this approach the Rabbi Trusts would not
be consolidated and therefore, for purposes of the pro forma presentation, such
assets and liabilities and their related income and expenses have been
eliminated from the statement of financial condition and income statement,
respectively.

     g. Income Taxes

Records the tax effect pertaining to the conversion from U.S. GAAP to IAS on the
unaudited consolidated statement of financial condition and income statement of
PaineWebber, assuming an effective tax rate of 37.3%.

     h. Redemption of Mandatorily Redeemable Preferred Stock

Under IAS, preferred shares having mandatory redemption features are classified
as debt with associated dividends recognized in interest expense. For purposes
of pro forma presentation, the Unamortized discount charged to equity on
redemption of preferred stock and Dividends and amortization of discount on
preferred stock, thereon, have been reclassified as Interest expense.

     i. Trust Preferred Securities

Under IAS, trust preferred securities having mandatory redemption features are
classified as debt with associated dividends recognized in interest expense. For
purposes of pro forma presentation, Company Obligated Mandatorily Redeemable
Preferred Securities of Subsidiary Trusts have been reclassified to Long-term
debt and the related Minority interest expense to Interest expense.

     j. Brokerage, Clearing and Exchange Fees

PaineWebber records certain brokerage, clearing and exchange fees as separate
components of expense for purposes of its U.S. GAAP financial statements. Under
IAS, expenses directly connected with a transaction are charged against
revenues.

     k. Private Equity Investments

PaineWebber carries private equity related investments for which there exist
trading restrictions at estimated net realizable value under U.S. GAAP. UBS
records similar investments at cost, less writedowns for impairments in value.
This adjustment reverses unrealized gains on such investments reflected in the
PaineWebber accounts.

                    AND FOR THE YEAR ENDED 31 DECEMBER 1999

1. IAS TO U.S. GAAP ADJUSTMENTS

IAS accounting principles differ in material respects from accounting principles
generally accepted in the U.S. The differences which are material to restating
the historical consolidated financial statements of UBS and PaineWebber to
comply with U.S. GAAP, are described below.

ADJUSTMENTS TO UBS AND PAINEWEBBER UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
BALANCE SHEETS AND INCOME STATEMENTS

The differences which are material to restating the UBS unaudited pro forma
consolidated balance sheets and income statements to U.S. GAAP relate to
purchase accounting, restructuring provisions, derivatives held for non-trading
purposes, financial investments, retirement and benefit plans, other employee
benefits, equity participation plans, software capitalization, settlement date
vs. trade date accounting and repurchase, resale and securities lending
transactions as described in notes (a), (b), (c), (d), (e), (f), (g), (h), (i)
and (j), respectively. PaineWebber's IAS to U.S. GAAP adjustments have been
documented in the notes to the PaineWebber unaudited pro forma condensed
consolidated statement of financial condition and income statement: conversion
from U.S. GAAP to IAS, note #2: U.S. GAAP to IAS adjustments. In addition, for
purposes of conforming PaineWebber's accounts to UBS's presentation under U.S.
GAAP, certain investments have been reclassified from financial investments to
Other Assets.

  a. Purchase Accounting

     General

Under IAS, UBS accounted for the 1998 merger of Union Bank of Switzerland and
Swiss Bank Corporation under the pooling of interests method. The balance sheets
and income statements of the banks were combined and no adjustments to the
carrying values of the assets and liabilities were made.

Under U.S. GAAP, the business combination creating UBS is accounted for under
the purchase method with Union Bank of Switzerland being considered the
accounting acquirer. Under the purchase method, the cost of acquisition is
measured at fair value and the acquirer's interests in identifiable tangible
assets and liabilities of the acquiree are restated to fair values at the date
of acquisition. Any excess consideration paid over the fair value of net
tangible assets acquired is allocated, first to identifiable intangible assets
based on their fair values, if determinable, with the remainder allocated to
goodwill.

     Goodwill

Under U.S. GAAP, goodwill and other intangible assets acquired are capitalized
and amortized over the expected periods to be benefited with adjustments, if
any, for impairment.

For purposes of the U.S. GAAP reconciliation, the excess of the consideration
paid for Swiss Bank Corporation over the fair value of the net tangible assets
received has been recorded as Goodwill and is being amortized on a straight line
basis over a weighted average life of 13 years beginning 29 June 1998.

                CONSOLIDATED BALANCE SHEET AND INCOME STATEMENT
                CONVERSION FROM IAS TO U.S. GAAP -- (CONTINUED)

     Other Purchase Accounting Adjustments

For purposes of the U.S. GAAP reconciliation, the restatement of Swiss Bank
Corporation's net assets to fair value resulted in decreasing net tangible
assets by CHF 1,077 million. This amount will be amortized over a period ranging
from 2 years to 20 years depending upon the nature of the restatement.

  b. Restructuring Provision

Under IAS, restructuring provisions are recognized when a legal or constructive
obligation has been incurred. In 1997, UBS recognized a CHF 7,000 million
restructuring provision to cover personnel, information technology ("IT"),
premises and other costs associated with combining and restructuring the merged
Group. An additional CHF 300 million provision was recognized in the fourth
quarter of 1999, reflecting the impact of increased precision in the estimation
of certain leased and owned property costs.

Under U.S. GAAP, restructuring provisions for business combinations are not
recognized prior to the consummation date of the business combination. Also, the
criteria for establishing liabilities of this nature are more stringent than
under IAS. Established restructuring provisions are required to be periodically
reviewed for appropriateness and revised if necessary.

For purposes of the U.S. GAAP reconciliation, the aggregate CHF 7,300 million
restructuring provision was reversed. As a result of the business combination
with Swiss Bank Corporation, the decision to combine and streamline certain
activities of the banks for the purpose of reducing costs and improving
efficiencies, Union Bank of Switzerland recognized a restructuring provision of
CHF 1,575 million during 1998 for purposes of the U.S. GAAP reconciliation. CHF
759 million of this provision related to estimated costs for restructuring the
operations and activities of Swiss Bank Corporation and such amount was recorded
as a liability of the acquired business. The remaining CHF 816 million of
estimated costs were charged to restructuring expense during 1998. Adjustments
of CHF 130 million and 600 million to the restructuring provision were
recognized in the six months ended 30 June 2000 and in the year ended 31
December 1999, respectively, for purposes of the U.S. GAAP reconciliation. The
reserve is expected to be substantially exhausted by the end of 2001.

The restructuring provision initially included CHF 756 million for employee
termination benefits, CHF 332 million for the closure and write downs of owned
and leased premises, and CHF 487 million for professional fees, IT costs,
miscellaneous transfer taxes and statutory fees.

The usage of the U.S. GAAP restructuring provision was as follows:

         NOTES TO THE UBS AND PAINEWEBBER UNAUDITED PRO FORMA CONDENSED
                CONSOLIDATED BALANCE SHEET AND INCOME STATEMENT
                CONVERSION FROM IAS TO U.S. GAAP -- (CONTINUED)

Additionally, for purposes of the U.S. GAAP reconciliation, nil and CHF 150
million of restructuring costs were expensed as incurred in the six months ended
30 June 2000 and the year ended 31 December 1999, respectively.

  c. Derivatives Instruments Held or Issued for Non-Trading Purposes

Under IAS, UBS recognizes transactions in derivative instruments hedging
non-trading positions in the income statement using the accrual or deferral
method, which is generally the same accounting as the underlying item being
hedged.

U.S. GAAP requires that derivatives be reported at fair value with changes in
fair value recorded in income unless specified criteria are met to obtain hedge
accounting treatment (accrual or deferral method).

UBS is not required to comply with all of the criteria necessary to obtain hedge
accounting treatment under U.S. GAAP. Accordingly, for purposes of the U.S. GAAP
reconciliation, derivative instruments held or issued for non-trading purposes
that did not meet U.S. GAAP hedging criteria have been carried at fair value
with changes in fair value recognized as adjustments to net trading income.

  d. Financial Investments

Under IAS, financial investments are classified as either current investments or
long-term investments. UBS considers current financial investments to be held
for sale and carried at lower of cost or market value. UBS accounts for
long-term financial investments at cost, less any permanent impairment.

Under U.S. GAAP, investments are classified as either held to maturity
(essentially debt securities), which are carried at amortized cost, or available
for sale (debt and marketable equity securities), which are carried at fair
value with changes in fair value recorded as a separate component of
shareholders' equity. Realized gains and losses are recognized in net profit in
the period sold.

For purposes of the U.S. GAAP reconciliation, amounts reflected in Other income
for the changes in market values of held for sale investments are reclassified
as a component of Shareholders' equity. Held to maturity investments that do not
meet U.S. GAAP criteria are reclassified to the available for sale category.
Unrealized gains or unrealized losses relating to these investments are recorded
as a component of Shareholders' equity.

  e. Retirement Benefit Plans

Under IAS, UBS has recorded pension expense based on a specific method of
actuarial valuation of projected plan liabilities for accrued service including
future expected salary increases and expected return on plan assets. Plan assets
are held in a separate trust to satisfy plan liabilities. Plan assets are
recorded at fair value. The recognition of a prepaid asset on the books of UBS
is subject to certain limitations. These limitations generally cause amounts
recognized as expense to equal amounts funded in the same period. Any amount not
recognized as a prepaid asset and the corresponding impact on pension expense
has been disclosed in the financial statements.

Under U.S. GAAP, pension expense, generally, is based on the same method of
valuation of liabilities and assets as under IAS. Differences in the levels of
expense and liabilities (or prepaid assets) exist due to the different
transition date rules and the stricter provisions of IAS as well as industry
practice under IAS for recognition of a prepaid asset.

         NOTES TO THE UBS AND PAINEWEBBER UNAUDITED PRO FORMA CONDENSED
                CONSOLIDATED BALANCE SHEET AND INCOME STATEMENT
                CONVERSION FROM IAS TO U.S. GAAP -- (CONTINUED)

As a result of the merger of the retirement benefit plans of Union Bank of
Switzerland and Swiss Bank Corporation after the 1998 merger, there was a one
time increase of the vested plan benefits for the beneficiaries of such plans.
This had the effect of increasing the defined benefit obligation at this date by
CHF 3,020 million. Under IAS this resulted in a one-time charge to income which
was offset by the recognition of assets (previously unrecognized due to certain
limitations under IAS).

Under U.S. GAAP, in a business combination that is accounted for under the
purchase method, the assignment of the purchase price to individual assets
acquired and liabilities assumed must include a liability for the projected plan
liabilities in excess of plan assets or an asset for plan assets in excess of
the projected plan liabilities, thereby recognizing any previously existing
unrecognized net gains or losses, unrecognized prior service cost, or
unrecognized net liabilities or assets.

For purposes of the U.S. GAAP reconciliation, UBS recorded a prepaid asset for
the Union Bank of Switzerland plans as of 1 January 1998. Swiss Bank Corporation
recorded a purchase price adjustment to recognize its prepaid asset at 29 June
1998. The recognition of these assets impacts the pension expense recorded under
U.S. GAAP versus IAS. The pension expense for the year ended 31 December 1999 is
also impacted by the different treatment of the merger of the plans under IAS
versus U.S. GAAP. The assets recognized under IAS (which had been previously
unrecognized due to certain limitations under IAS) were already recognized under
U.S. GAAP due to the absence of such limitations under U.S. GAAP.

  f. Other Employee Benefits

Under IAS, UBS has recorded expenses and liabilities for post-retirement
benefits determined under a methodology similar to that described above under
retirement benefit plans.

Under U.S. GAAP, expenses and liabilities for post-retirement benefits would be
determined under a similar methodology as under IAS. Differences in the levels
of expenses and liabilities have occurred due to different transition date rules
and the treatment of the merger of Union Bank of Switzerland and Swiss Bank
Corporation under the purchase method.

  g. Equity participation plans

IAS does not specifically address the recognition and measurement requirements
for equity participation plans.

U.S. GAAP permits the recognition of compensation cost on the grant date for the
estimated fair value of equity instruments issued (Statement of Financial
Accounting Standards No. 123) or based on the intrinsic value of equity
instruments issued (Accounting Principles Board Opinion No. 25), with the
disclosure of the pro forma effects of equity participation plans on net profit
and earnings per share, as if the fair value had been recorded on the grant
date. UBS recognized only intrinsic values at the grant date with subsequent
changes in value not recognized.

For purposes of the U.S. GAAP reconciliation, certain of UBS's option awards
have been determined to be variable, primarily because they may be settled in
cash or UBS has offered to hedge their value. Additional compensation expense
from these options awards for the six months ended 30 June and the year ended 31
December 1999, is CHF 44 million and CHF 41 million, respectively. In addition,
certain of UBS's equity participation plans provide for deferral of the awards,
and the instruments are held in trusts for the participants. Certain of these
trusts are recorded on UBS's balance sheet for U.S.

         NOTES TO THE UBS AND PAINEWEBBER UNAUDITED PRO FORMA CONDENSED
                CONSOLIDATED BALANCE SHEET AND INCOME STATEMENT
                CONVERSION FROM IAS TO U.S. GAAP -- (CONTINUED)

GAAP presentation, the effect of which is to increase assets by CHF 1,070
million and CHF 655 million, liabilities by CHF 1,162 million and CHF 717
million, and decrease shareholders' equity by CHF 92 million and CHF 62 million
(for UBS shares held by the trusts, which are treated as treasury shares) at 30
June 2000 and 31 December 1999, respectively.

  h. Software capitalization

Under IAS, effective 1 January 2000, certain costs associated with the
acquisition or development of internal use software are required to be
capitalized. Once the software is ready for its intended use, the costs
capitalized are amortized to the income statement over estimated lives. Under
U.S. GAAP, the same principal applies; however this standard was effective
beginning 1 January 1999. For purposes of the U.S. GAAP reconciliation, the
costs associated with the acquisition or development of internal use software
that met the U.S. GAAP software capitalization criteria in 1999 have been
reversed from Operating expenses and amortized over a life of 2 years. From 1
January 2000, the only remaining reconciliation item is the amortization of
software capitalized in 1999 for U.S. GAAP purposes.

  i. Settlement Date vs. Trade Date Accounting

UBS's transactions from securities activities are recorded on the settlement
date for balance sheet and on the trade date for income statement purposes. This
results in recording an off-balance sheet forward transaction during the period
between the trade date and the settlement date. Forward positions relating to
trading activities are revalued to fair value and any unrealized profits and
losses are recognized in Net profit.

Under U.S. GAAP, trade date accounting is required for purchases and sales of
securities. For purposes of U.S. GAAP presentation, all purchases and sales of
securities previously recorded on settlement date have been recorded as of trade
date for balance sheet purposes. Trade date accounting has resulted in
receivables and payables to broker-dealers and clearing organizations recorded
in Other assets and Other liabilities.

  j. Repurchase, Resale and Securities Lending Transactions

Under IAS, UBS's repurchase agreements and securities borrowed are accounted for
as collateralized borrowings. Reverse repurchase agreements and securities
lending are accounted for as collateralized lending transactions. Cash
collateral is reported on the balance sheet at amounts equal to the collateral
advanced or received.

Under U.S. GAAP, securities lending and repurchase transactions are also
generally accounted for as collateralized borrowing and lending transactions.
However, certain such transactions may be deemed sale or purchase transactions
under specific circumstances. Additionally, under U.S. GAAP, UBS is required to
recognize securities collateral controlled and an offsetting obligation to
return such securities collateral on certain financing transactions, when
specific control conditions exist.

For purposes of U.S. GAAP presentation, securities collateral recognized under
financing transactions is reflected in Due from banks or loans, net of allowance
for credit losses, depending on the counterparty. The related obligation to
return the securities collateral is reflected in the balance sheet in Due to
banks or Due to customers, as appropriate.

2. CONVENIENCE TRANSACTION

30 June 2000 and 31 December 1999 CHF amounts have been translated into U.S.
dollars at the exchange rate of one US$ = CHF 1.63, the exchange rate on 30 June
2000.

3. PROPOSED DIVIDEND

At the extraordinary general meeting of UBS AG, held on 7 September 2000, the
UBS shareholders approved the UBS Board of Directors proposal that a partial
dividend be paid to UBS shareholders on record as of 2 October 2000. The
payment, which was made on 5 October 2000, relates to the first nine months of
the year 2000. The payment of $2.75 (CHF 4.50) per share amounted to
approximately $1.1 billion (CHF 1.8 billion).

DESCRIPTION OF NOTES WE MAY OFFER

Please note that in this section entitled "Description of Notes We May Offer,"
references to UBS, we, our and us refer only to UBS AG and not to its
consolidated subsidiaries. Also, in this section, references to Holders mean
those who own notes registered in their own names on the books that we or the
trustee maintain for this purpose, and not those who own beneficial interests in
notes registered in street name or in notes issued in book-entry form through
one or more depositaries. Owners of beneficial interests in the notes should
read the subsection below entitled "-- Legal Ownership of Notes."

INFORMATION ABOUT OUR MEDIUM-TERM NOTES PROGRAM

THE NOTES WILL BE ISSUED UNDER THE INDENTURE
As required by U.S. federal law for publicly offered bonds and notes, the notes
are governed by a document called the indenture. The indenture is a contract
between us and U.S. Bank Trust National Association, which acts as trustee. The
trustee has two main roles:

     - First, the trustee can enforce your rights against us if we default.
       There are limitations on the extent to which the trustee acts on your
       behalf, which we describe below under "Default, Remedies and Waiver of
       Default."

     - Second, the trustee performs administrative duties for us, such as
       sending you interest payments and notices.

WE MAY ISSUE OTHER SERIES OF DEBT SECURITIES
The indenture permits us to issue different series of debt securities from time
to time. The Series A medium-term notes will be a single distinct series of debt
securities. We may, however, issue Series A notes in such amounts, at such times
and on such terms as we wish. The notes will differ from one another, and from
other series, in their terms.

This section summarizes the material terms that will apply generally to the
notes as a series. Each particular note will have financial and other terms
specific to it, and the specific terms of each note will be described in a
prospectus supplement that will be delivered with this prospectus. Those terms
may vary from the terms described here. As you read this section, therefore,
please remember that the specific terms of your note as described in your
prospectus supplement will supplement and, if applicable, may modify or replace
the general terms described in this section. The statements we make in this
section may not apply to your note.

When we refer to the notes, the Series A medium-term notes or these notes, we
mean the medium-term notes, Series A. When we refer to a series of debt
securities, we mean a series, such as the notes, issued under the indenture.
When we refer to your prospectus supplement, we mean the prospectus supplement
describing the specific terms of the note you purchase.

AMOUNTS THAT WE MAY ISSUE
The indenture does not limit the aggregate amount of debt securities that we may
issue, nor does it limit the number of series or the aggregate amount of any
particular series. We have authorized the issuance of Series A medium-term notes
in such amounts as will not result in the notes having an aggregate initial
offering price greater than $2,000,000,000, or an equivalent amount in any other
currency or currency unit.

The indenture and the notes do not limit our ability to incur other indebtedness
or to issue other securities. Also, we are not subject to financial or similar
restrictions by the terms of the notes.

--------------------------------------------------------------------------------
                                                                             151
<PAGE>   184
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

HOW THE NOTES RANK AGAINST OTHER DEBT
The Series A medium-term notes will not be secured by any property or assets of
UBS or its subsidiaries. Thus, by owning a note, you will be one of our
unsecured creditors.

The notes will not be subordinated to any of our other debt obligations. This
means that, in a bankruptcy or liquidation proceeding against us, the notes
would rank equally in right of payment with all other unsecured and
unsubordinated debt of UBS, except for debts required to be preferred by law.
The notes are not deposit liabilities of UBS and are not insured by the United
States Federal Deposit Insurance Corporation or any other governmental agency of
the United States, Switzerland or any other jurisdiction.

THIS SECTION IS ONLY A SUMMARY
The indenture and its associated documents, including your note, contain the
full legal text governing the matters described in this section and your
prospectus supplement. The indenture and the notes are governed by New York law.
A copy of the indenture has been filed with the SEC as part of our registration
statement. See "Where You Can Find More Information" below for information on
how to obtain a copy.

This section and your prospectus supplement summarize all the material terms of
the indenture and your note. They do not, however, describe every aspect of the
indenture and your note. For example, in this section and your prospectus
supplement, we use terms that have been given special meaning in the indenture,
but we describe the meaning of only the more important of those terms.

FEATURES COMMON TO ALL NOTES

STATED MATURITY AND MATURITY
The day on which the principal amount of your note is scheduled to become due is
called the stated maturity of the principal and is specified in your prospectus
supplement. The principal may become due sooner, by reason of redemption or
acceleration after a default. A redemption may occur at our option, at your
option, or both, or as a term of the note, as described in your prospectus
supplement. The day on which the principal actually becomes due, whether at the
stated maturity or earlier, is called the maturity of the principal.

We also use the terms "stated maturity" and "maturity" to refer to the dates
when other payments become due. For example, we may refer to a regular interest
payment date when an installment of interest is scheduled to become due as the
"stated maturity" of that installment. When we refer to the "stated maturity" or
the "maturity" of a note, without specifying a particular payment, we mean the
stated maturity or maturity, as applicable, of the principal.

CURRENCY OF NOTES
Amounts that become due and payable on your note will be payable in a currency,
composite currency, basket of currencies or currency units specified in your
prospectus supplement.

We refer to this currency, composite currency, basket of currencies or currency
unit or units as a specified currency. The specified currency for your note will
be U.S. dollars, unless your prospectus supplement states otherwise. Some notes
may have different specified currencies for principal and interest.

You will have to pay for your notes by delivering the requisite amount of the
specified currency for the principal to UBS Warburg LLC, PaineWebber
Incorporated or another agent or dealer that we name in your prospectus
supplement, unless other arrangements have been made between you and us or you
and that agent or dealer. We will make payments on your notes in the specified
currency, except as described below under the heading "-- Payment Mechanics."

DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

TYPES OF DEBT SECURITIES
We may issue various kinds of notes, including the following types of notes:

     - Fixed Rate Notes.  A note of this type will bear interest at a fixed rate
       described in the applicable prospectus supplement. This type includes
       zero coupon notes, which bear no interest and are instead issued at a
       price lower than the principal amount payable at stated maturity.

     - Floating Rate Notes.  A note of this type will bear interest at rates
       that are determined by reference to an interest rate formula based on one
       or more than one base interest rate. In some cases, the interest rate on
       your notes may also be adjusted by adding or subtracting a spread or
       multiplying by a spread multiplier and may be subject to a minimum rate
       or a maximum rate. The various base interest rates that will be used in
       these formulas, and these other features, are described below under
       "-- Interest Rates -- Floating Rate Notes." If your note is a floating
       rate note, the formula, the base interest rates used in the formula and
       any adjustments that will apply to your notes will be described in your
       prospectus supplement.

     - Equity Indexed Notes.  A note of this type provides that the principal
       amount payable at its maturity, and/or the amount of interest payable on
       an interest payment date, will be determined by reference to one or more
       equity securities or stocks, including baskets of stocks and stock
       indices, or to any other equity index described in your prospectus
       supplement. If you are a Holder of an equity indexed note, you may
       receive a principal amount at maturity that is greater than or less than
       the face amount of your note depending upon the value of the relevant
       stock or index at maturity. That value may fluctuate over time. Some
       equity indexed notes may also be exchangeable, at the option of the
       Holder or UBS, into equity securities of one or more issuers other than
       UBS. If you purchase an equity indexed note, your prospectus supplement
       will include information about the relevant index and about how amounts
       that are to become payable will be determined by reference to that index.
       Before you purchase any indexed note, you should read carefully the risk
       factors that are specified in your prospectus supplement.

     - Credit Indexed Notes.  A note of this type provides that the principal
       amount payable at its maturity, and/or the amount of interest payable on
       an interest payment date, will be determined by reference to one or more
       loans, debt securities or evidences of indebtedness, notes and/or bonds,
       including baskets of notes, bonds, or loans, note indices and bond
       indices, or to any other credit or credit related index described in your
       prospectus supplement. If you are a Holder of a credit indexed note, you
       may receive a principal amount at maturity that is greater than or less
       than the face amount of your note depending upon the value of the
       relevant debt instruments or debt index at maturity. That value may
       fluctuate over time. Some credit indexed notes may also be exchangeable,
       at the option of the Holder or UBS, into debt of one or more issuers
       other than UBS. If you purchase an credit indexed note, your prospectus
       supplement will include information about the relevant index and about
       how amounts that are to become payable will be determined by reference to
       that index. Before you purchase any indexed note, you should read
       carefully the risk factors that are specified in your prospectus
       supplement.

     - Credit Linked Notes.  A note of this type provides that the principal
       amount payable at its maturity, and/or the amount of interest payable on
       an interest payment date, is dependent on whether or not a credit event
       (such as a bankruptcy or payment default) has occurred with respect to
       one or more specified reference entities' debt obligations. The notes may
       bear interest at a fixed, floating or variable rate of interest, as will
       be described in your prospectus supplement. If you are a Holder of a
       credit-linked note, your note may be redeemed prior to maturity for less
       than its face amount and you may not receive any interest for the
       interest period in which any of the specified credit events occurs with
       respect to the reference entity. If you purchase a credit-linked note,
       your prospectus supplement will contain a description of the

--------------------------------------------------------------------------------
                                                                             153

DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

       reference entity or entities, the obligations of the reference entity or
       entities to which your notes are linked, the potential credit events
       applicable with respect to each reference entity, and the effect that a
       credit event will have on the principal or interest payable on the notes
       or any other terms of the notes. Before you purchase any credit-linked
       note, you should read carefully the risk factors that are specified in
       your prospectus supplement.

We may also issue notes that are indexed or linked to any other asset,
liability, commodity, rate or index, or with any other type of feature
determining the amount of principal and interest that we will pay on the notes
and the timing of these payments. In addition, we can combine the types of
provisions described above, or any other special features, in a single offering
of notes. If these features apply to your notes, they will be described in your
prospectus supplement.

ORIGINAL ISSUE DISCOUNT NOTES
A fixed rate note, a floating rate note, an equity or credit indexed note, or a
credit-linked note or any other note may be an original issue discount note. A
note of this type is issued at a price lower than its principal amount and
provides that, upon redemption or acceleration of its maturity, an amount less
than its principal amount will be payable. An original issue discount note may
be a zero coupon note. A note issued at a discount to its principal may, for
U.S. federal income tax purposes, be considered an original issue discount note,
regardless of the amount payable upon redemption or acceleration of maturity.
See "U.S. Tax Considerations -- Original Issue Discount" below for a brief
description of the U.S. federal income tax consequences of owning an original
issue discount note.

INFORMATION IN THE PROSPECTUS SUPPLEMENT
Your prospectus supplement will describe one or more of the following terms of
your note:

     - the stated maturity;

     - the specified currency or currencies for principal and interest, if not
       U.S. dollars;

     - the price at which we will originally issue your note, expressed as a
       percentage of the principal amount, and the original issue date;

     - whether your note is a fixed rate note, a floating rate note, an equity
       indexed note, a credit indexed note, a credit-linked note or any other
       note, and also whether it is an original issue discount note;

     - if your note is a fixed rate note, the annual rate at which your note
       will bear interest, if any, and the interest payment dates, if different
       from those described below under "-- Interest Rates -- Fixed Rate Notes;"

     - if your note is a floating rate note, the interest rate basis, which may
       be one of the base rates described in "-- Interest Rates -- Floating Rate
       Notes" below; any applicable index currency or maturity, spread or spread
       multiplier or initial, maximum or minimum rate; the interest reset,
       determination, calculation and payment dates; the calculation agent; and
       whether the note is renewable, all of which we describe under
       "-- Interest Rates -- Floating Rate Notes" below;

     - if your note is an equity or credit indexed note, or a note indexed to
       any other reference or index, the principal amount we will pay you at
       maturity and the amount of interest we will pay you on an interest
       payment date, or the formulas we will use to calculate these amounts, and
       whether your note will be exchangeable for or payable in equity
       securities, debt securities or other debt obligations of one or more
       issuers (other than UBS) or any other property;

     - if your note is a credit linked note, the maturity, interest reset,
       determination, calculation and payment dates; the calculation agent; the
       amount of interest we will pay you on an interest

       payment date or the formula we will use to calculate this amount; the
       reference entity or entities; the obligations of the reference entity or
       entities to which the notes are linked; the credit events applicable to
       each reference entity; and the effect that any credit event will have on
       the principal or interest payable on the notes or on any other terms of
       the notes;

     - if your note is an original issue discount note, the yield to maturity;

     - whether your note may be redeemed at our option or repaid at the Holder's
       option prior to the stated maturity and, if so, other relevant terms such
       as the redemption commencement date, repayment date(s), redemption
       price(s) and redemption period(s), all of which we describe under
       "--Redemption and Repayment" below;

     - whether your note may be converted or exchanged at your option or our
       option into other securities or property (including other securities of
       UBS) in addition to or in place of any payments of interest or principal,
       and, if so, other relevant terms;

     - whether we will issue your note or make it available in non-book-entry
       form;

     - whether the stated maturity of your note may be extended and, if so,
       other relevant terms; and

     - any other terms of your note that are not inconsistent with the
       provisions of the indenture, which other terms could be different from
       those described in this prospectus.

If you purchase your note in a market-making transaction, you will receive
information about the price you pay and your trade and settlement dates in a
separate confirmation of sale. A market-making transaction is one in which UBS,
UBS Warburg LLC, PaineWebber Incorporated or another of our affiliates resells a
note that it has previously acquired from another holder. A market-making
transaction in a particular note occurs after the original issuance and sale of
the note.

Your prospectus supplement will summarize the specific financial and other terms
of your note, while this prospectus describes terms that apply generally to the
notes. Consequently, the terms described in your prospectus supplement will
supplement those described in this prospectus and, if the terms described there
are inconsistent with those described here, the terms described in the
prospectus supplement will be controlling. The terms used in your prospectus
supplement have the meanings described in this prospectus, unless otherwise
specified in the prospectus supplement.

WHAT IS A GLOBAL NOTE?

We will issue each note in book-entry form only, unless we specify otherwise in
the applicable prospectus supplement. This means that interests in the note will
be represented and transferred through the rules of a book-entry clearing
system. Each note issued in book-entry form will be represented by a global note
that we deposit with and register in the name of a financial institution that we
select, or its nominee. The financial institution that we select for this
purpose is called the depositary. Unless we specify otherwise in the applicable
prospectus supplement, The Depository Trust Company, known as DTC, will be the
depositary for all notes issued in book-entry form.

A global note may represent one or any other number of individual notes.
Generally, all notes represented by the same global note will have the same
terms. We may, however, issue a global note that represents multiple notes that
have different terms and are issued at different times. We call this kind of
global note a master global note. Your prospectus supplement will not indicate
whether a global note is a master global note.

A global note may not be transferred to or registered in the name of anyone
other than the depositary or its nominee, unless special termination situations
arise. We describe those situations below under "--Special Situations When a
Global Note Will Be Terminated." As a result of these arrangements, the

--------------------------------------------------------------------------------
                                                                             155
<PAGE>   188
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

depositary, or its nominee, will be the sole registered owner and Holder of all
notes represented by a global note, and investors will be permitted to own only
beneficial interests in a global note. Beneficial interests must be held by
means of an account with a broker, bank or other financial institution that in
turn has an account with the depositary or with another institution that does.
Thus, an investor whose note is represented by a global note will not be a
Holder of the note, but only an indirect holder of a beneficial interest in the
global note.

If the prospectus supplement for a particular note indicates that the note will
be issued in global form only, then the note will be represented by a global
note at all times unless and until the global note is terminated. We describe
the situations in which this can occur below under "--Special Situations When a
Global Note Will Be Terminated." If termination occurs, we may issue the notes
through another book-entry clearing system or decide that the notes may no
longer be held through any book-entry clearing system.

SPECIAL CONSIDERATIONS FOR GLOBAL NOTES
As an indirect holder, an investor's rights relating to a global note will be
governed by the account rules of the investor's financial institution and of the
depositary, as well as general laws relating to securities transfers. We do not
recognize this type of investor as a Holder of notes and instead deal only with
the depositary that holds the global note.

If notes are issued only in the form of a global note, an investor should be
aware of the following:

     - An investor cannot cause the notes to be registered in his or her own
       name, and cannot obtain non-global certificates for his or her interest
       in the notes, except in the special situations we describe below under
       "--Special Situations When a Global Note Will Be Terminated."

     - An investor will be an indirect holder and must look to his or her own
       bank or broker for payments on the notes and protection of his or her
       legal rights relating to the notes, as we describe below under "--Legal
       Ownership of Notes."

     - An investor may not be able to sell his or her interest in the notes to
       some insurance companies and other institutions that are required by law
       to own their securities in non-book-entry form.

     - An investor may not be able to pledge his or her interest in a global
       note in circumstances where certificates representing the notes must be
       delivered to the lender or other beneficiary of the pledge in order for
       the pledge to be effective.

     - The depositary's policies, which may change from time to time, will
       govern payments, transfers, exchanges and other matters relating to an
       investor's interest in a global note. We and the trustee have no
       responsibility for any aspect of the depositary's actions or for its
       records of ownership interests in a global note. We and the trustee also
       do not supervise the depositary in any way.

     - The depositary will require that those who purchase and sell interests in
       a global note within its book-entry system use immediately available
       funds and your broker or bank may require you to do so as well.

     - Financial institutions that participate in the depositary's book-entry
       system, and through which an investor holds its interest in the global
       notes, may also have their own policies affecting payments, notices and
       other matters relating to the notes. There may be more than one financial
       intermediary in the chain of ownership for an investor. We do not monitor
       and are not responsible for the actions of any of those intermediaries.

SPECIAL SITUATIONS WHEN A GLOBAL NOTE WILL BE TERMINATED
In a few special situations described below, a global note will be terminated
and interests in it will be exchanged for certificates in non-global form
representing the notes it represented. After that exchange, the choice of
whether to hold the notes directly or in street name will be up to the investor.
Investors must consult their own banks or brokers to find out how to have their
interests in a global note transferred on termination to their own names, so
that they will be Holders. We have described the rights of Holders and street
name investors below under "--Legal Ownership of Notes."

Unless the applicable prospectus supplement identifies additional situations,
the only special situations for termination of a global note are as follows:

     - if the depositary notifies us that it is unwilling, unable or no longer
       qualified to continue as depositary for that global note and we do not
       appoint another institution to act as depositary within 60 days;

     - if we notify the trustee that we wish to terminate that global note; or

     - if an event of default has occurred with regard to notes represented by
       that global note and has not been cured or waived; we discuss defaults
       below under "--Default, Remedies and Waiver of Default."

If a global note is terminated, only the depositary, and not we or the trustee,
is responsible for deciding the names of the institutions in whose names the
notes represented by the global note will be registered and, therefore, who will
be the Holders of those notes.

LEGAL OWNERSHIP OF NOTES

We refer to those who have notes registered in their own names, on the books
that we or the trustee maintain for this purpose, as the "Holders" of those
notes. These persons are the legal holders of the notes. We refer to those who,
indirectly through others, own beneficial interests in notes that are not
registered in their own names as indirect holders of those notes. As we discuss
below, indirect holders are not legal holders, and investors in notes issued in
book-entry form or in street name will be indirect holders.

BOOK-ENTRY HOLDERS
We will issue each note in book-entry or global form only, unless we specify
otherwise in the applicable prospectus supplement. This means notes will be
represented by one or more global notes registered in the name of a financial
institution that holds them as depositary on behalf of other financial
institutions that participate in the depositary's book-entry system. These
participating institutions, in turn, hold beneficial interests in the notes on
behalf of themselves or their customers.

As a result, investors will not own notes directly. Instead, they will own
beneficial interests in a global note, through a bank, broker or other financial
institution that participates in the depositary's book-entry system or holds an
interest through a participant. As long as the notes are issued in book-entry
form, investors will be indirect holders, and not Holders, of the notes.

Under the indenture, only the person in whose name a note is registered is
recognized as the Holder of that note. Consequently, for notes issued in
book-entry form, we will recognize only the depositary as the Holder of the
notes and we will make all payments on the notes to the depositary. The
depositary will pass along the payments it receives to its participants, which
in turn will pass the payments along to their customers who are the beneficial
owners, but only because they agree to do so in their customer agreements or
because they are legally required to do so.

DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

STREET NAME HOLDERS
We may terminate a global note described above or issue notes initially in
non-global or definitive form. In these cases, investors may choose to hold
their notes in their own names or in "street name." Notes held by an investor in
street name would be registered in the name of a bank, broker or other financial
institution that the investor chooses, and the investor would hold only a
beneficial interest in those notes through an account he or she maintains at
that institution.

For notes held in street name, we will recognize only the intermediary banks,
brokers and other financial institutions in whose names the notes are registered
as the Holders of those notes and we will make all payments on those notes to
them. These institutions will pass along the payments they receive to their
customers who are the beneficial owners, but only because they agree to do so in
their customer agreements or because they are legally required to do so.
Investors who hold notes in street name will be indirect holders, not Holders,
of the notes.

LEGAL HOLDERS
Our obligations, as well as the obligations of the trustee and those of any
third parties employed by us or the trustee, run only to the Holders of the debt
securities. We do not have obligations to investors who hold beneficial
interests in global notes, in street name or by any other indirect means. This
will be the case whether an investor chooses to be an indirect holder of a note
or has no choice because we are issuing the notes only in book-entry form.

For example, once we make a payment or give a notice to the Holder, we have no
further responsibility for that payment or notice even if that Holder is
required, under agreements with depositary participants or customers or by law,
to pass it along to the indirect holders but does not do so. Similarly, if we
want to obtain the approval of the Holders for any purpose--for example, to
amend the indenture or to relieve us of the consequences of a default or of our
obligation to comply with a particular provision of the indenture--we would seek
the approval only from the Holders, and not the indirect holders, of the notes.
Whether and how the Holders contact the indirect holders is up to the Holders.

When we refer to you, we mean those who invest in the notes being offered by
this prospectus, whether they are the Holders or only indirect holders of those
notes. When we refer to your notes, we mean the notes in which you hold a direct
or indirect interest.

SPECIAL CONSIDERATIONS FOR INDIRECT HOLDERS
If you hold notes through a bank, broker or other financial institution, either
in book-entry form or in street name, you should check with your own institution
to find out:

     - how it handles securities payments and notices;

     - whether it imposes fees or charges;

     - how it would handle a request for the Holders' consent, if ever required;

     - whether and how you can instruct it to send you notes registered in your
       own name so you can be a Holder, if that is permitted;

     - how it would exercise rights under the notes if there were a default or
       other event triggering the need for Holders to act to protect their
       interests; and

     - if the notes are in book-entry form, how the depositary's rules and
       procedures will affect these matters.

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

INTEREST RATES

This subsection describes general terms relating to the different kinds of
interest rates that may apply to your note, if it bears interest.

Please remember that the specific terms of your note as described in your
prospectus supplement will supplement and, if applicable, may modify or replace
the general terms regarding interest rates and payments of interest described in
this subsection. The statements we make in this subsection may not apply to your
note.

FIXED RATE NOTES
Each fixed rate note, except a zero coupon note, will bear interest from its
original issue date or from the most recent date to which interest on the debt
security has been paid or made available for payment. Interest will accrue on
the principal of a fixed rate note at the fixed yearly rate stated in the
applicable pricing supplement, until the principal is paid or made available for
payment. Unless otherwise specified in the applicable pricing supplement,
interest on a fixed rate note will be payable semi-annually each May 15 and
November 15, which will be the interest payment dates for the fixed rate note,
and at maturity. Each payment of interest due on an interest payment date or at
maturity will include interest accrued from and including the last date to which
interest has been paid, or made available for payment, or from the issue date if
none has been paid or made available for payment, to but excluding the interest
payment date or the date of maturity. We will compute interest on fixed rate
notes on the basis of a 360-day year of twelve 30-day months. We will make each
interest payment as described below under "--Payment Mechanics."

FLOATING RATE NOTES
In this subsection, we use several specialized terms relating to the manner in
which floating interest rates are calculated. These terms appear in BOLD type
the first time they appear, and we define these terms in "--Special Rate
Calculation Terms" at the end of this subsection.

Each floating rate note will bear interest from its original issue date or from
the most recent date to which interest on the note has been paid or made
available for payment. Interest will accrue on the principal of a floating rate
note at the rate determined according to the interest rate formula stated in the
applicable pricing supplement, until the principal is paid or made available for
payment. Interest on a floating rate note will be payable on each interest
payment date specified in the applicable prospectus supplement and at maturity.
We will rate each interest payment as described under "--Payment Mechanics"
below.

BASE RATES.  We currently expect to issue floating rate notes that bear interest
at rates based on one or more of the following base rates:

     - commercial paper rate

     - prime rate

     - LIBOR

     - EURIBOR

     - treasury rate

     - CMT rate

     - CD rate

     - federal funds rate

--------------------------------------------------------------------------------
                                                                             159
<PAGE>   192
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

     - J.J. Kenny rate

     - 11th district cost of funds rate

We describe each of these base rates in further detail below in this subsection.
If you purchase a floating rate note, your pricing supplement will specify the
type of base rate that applies to your note.

INITIAL BASE RATE.  For any floating rate note, the base rate in effect from the
original issue date to the first interest reset date will be the initial base
rate. We will specify the initial base rate in the applicable pricing
supplement.

SPREAD OR SPREAD MULTIPLIER.  In some cases, the base rate for a floating rate
note may be adjusted:

     - by adding or subtracting a specified number of basis points, called the
       spread, with one basis point being 0.01%; or

     - by multiplying the base rate by a specified percentage, called the spread
       multiplier.

If you purchase a floating rate note, your pricing supplement will specify
whether a spread or spread multiplier will apply to your note and, if so, the
amount of the spread or spread multiplier.

MAXIMUM AND MINIMUM RATES.  The actual interest rate, after being adjusted by
the spread or spread multiplier, may also be subject to either or both of the
following limits:

     - a maximum rate -- i.e., a specified upper limit that the actual interest
       rate in effect at any time may not exceed; and/or

     - a minimum rate -- i.e., a specified lower limit that the actual interest
       rate in effect at any time may not fall below.

If you purchase a floating rate note, your pricing supplement will specify
whether a maximum rate and/or minimum rate will apply to your note and, if so,
what those rates are.

Whether or not a maximum rate applies, the interest rate on a floating rate note
will in no event be higher than the maximum rate permitted by New York law, as
it may be modified by U.S. law of general application. Under current New York
law, the maximum rate of interest, with some exceptions, for any loan in an
amount less than $250,000 is 16% and for any loan in the amount of $250,000 or
more but less than $2,500,000 is 25% per year on a simple interest basis. These
limits do not apply to loans of $2,500,000 or more.

The rest of this subsection describes how the interest rate and the interest
payment dates will be determined, and how interest will be calculated, on a
floating rate note.

INTEREST RESET DATES.  The interest rate on a floating rate note will be reset,
by the calculation agent described below, daily, weekly, monthly, quarterly,
semi-annually or annually. The date on which the interest rate resets and the
reset rate becomes effective is called the interest reset date. Except as
otherwise specified in the applicable pricing supplement, the interest reset
date will be as follows:

     - for floating rate notes that reset daily, each BUSINESS DAY;

     - for floating rate notes that reset weekly and are not treasury rate
       notes, the Wednesday of each week;

     - for treasury rate notes that reset weekly, the Tuesday of each week,
       except as otherwise described in the next to last paragraph under
       "--Interest Determination Dates" below;

     - for floating rate notes that reset monthly, the third Wednesday of each
       month;

--------------------------------------------------------------------------------
 160
<PAGE>   193
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

     - for floating rate notes that reset quarterly, the third Wednesday of
       March, June, September and December of each year;

     - for floating rate notes that reset semi-annually, the third Wednesday of
       each of two months of each year as specified in the applicable pricing
       supplement; and

     - for floating rate notes that reset annually, the third Wednesday of one
       month of each year as specified in the applicable pricing supplement.

For a floating rate note, the interest rate in effect on any particular day will
be the interest rate determined with respect to the latest interest reset date
that occurs on or before that day. There are several exceptions, however, to the
reset provisions described above.

The base rate in effect from the original issue date to the first interest reset
date will be the initial base rate. For floating rate notes that reset daily or
weekly, the base rate in effect for each day following the second business day
before an interest payment date to, but excluding, the interest payment date,
and for each day following the second business day before the maturity to, but
excluding, the maturity, will be the base rate in effect on that second business
day.

If any interest reset date for a floating rate note would otherwise be a day
that is not a business day, the interest reset date will be postponed to the
next day that is a business day. For a LIBOR or EURIBOR note, however, if that
business day is in the next succeeding calendar month, the interest reset date
will be the immediately preceding business day.

INTEREST DETERMINATION DATES.  The interest rate that takes effect on an
interest reset date will be determined by the calculation agent by reference to
a particular date called an interest determination date. Except as otherwise
specified in the applicable pricing supplement:

     - For all floating rate notes other than LIBOR notes, EURIBOR notes,
       treasury rate notes and 11th district cost of funds rate notes, the
       interest determination date relating to a particular interest reset date
       will be the second business day before the interest reset date.

     - For LIBOR notes, the interest determination date relating to a particular
       interest reset date will be the second LONDON BUSINESS DAY preceding the
       interest reset date, unless the INDEX CURRENCY is pounds sterling, in
       which case the interest determination date will be the interest reset
       date. We refer to an interest determination date for a LIBOR note as a
       LIBOR interest determination date.

     - For EURIBOR notes, the interest determination date relating to a
       particular interest reset date will be the second EURO BUSINESS DAY
       preceding the interest reset date. We refer to an interest determination
       date for a EURIBOR note as a EURIBOR interest determination date.

     - For treasury rate notes, the interest determination date relating to a
       particular interest reset date, which we refer to as a treasury interest
       determination date, will be the day of the week in which the interest
       reset date falls on which treasury bills--i.e., direct obligations of the
       U.S. government--would normally be auctioned. Treasury bills are usually
       sold at auction on the Monday of each week, unless that day is a legal
       holiday, in which case the auction is usually held on the following
       Tuesday, except that the auction may be held on the preceding Friday. If
       as the result of a legal holiday an auction is held on the preceding
       Friday, that Friday will be the treasury interest determination date
       relating to the interest reset date occurring in the next succeeding
       week. If the auction is held on a day that would otherwise be an interest
       reset date, then the interest reset date will instead be the first
       business day following the auction date.

     - For 11th district cost of funds rate notes, the interest determination
       date relating to a particular interest reset date will be the last
       working day, in the first calendar month before that interest

--------------------------------------------------------------------------------
                                                                             161

       reset date, on which the Federal Home Loan Bank of San Francisco
       publishes the monthly average cost of funds paid by member institutions
       of the Eleventh Federal Home Loan Bank District for the second calendar
       month before that interest reset date. We refer to an interest
       determination date for an 11th district cost of funds rate note as an
       11th district interest determination date.

INTEREST CALCULATION DATES.  As described above, the interest rate that takes
effect on a particular interest reset date will be determined by reference to
the corresponding interest determination date. Except for LIBOR notes and
EURIBOR notes, however, the determination of the rate will actually be made on a
day no later than the corresponding interest calculation date. The interest
calculation date will be the earlier of the following:

     - the tenth calendar day after the interest determination date or, if that
       tenth calendar day is not a business day, the next succeeding business
       day; and

     - the business day immediately preceding the interest payment date or the
       maturity, whichever is the day on which the next payment of interest will
       be due.

The calculation agent need not wait until the relevant interest calculation date
to determine the interest rate if the rate information it needs to make the
determination is available from the relevant sources sooner.

INTEREST PAYMENT DATES.  The interest payment dates for a floating rate note
will depend on when the interest rate is reset and, unless we specify otherwise
in the applicable pricing supplement, will be as follows:

     - for floating rate notes that reset daily, weekly or monthly, the third
       Wednesday of each month or the third Wednesday of March, June, September
       and December of each year, as specified in the applicable pricing
       supplement;

     - for floating rate notes that reset quarterly, the third Wednesday of
       March, June, September and December of each year;

     - for floating rate notes that reset semi-annually, the third Wednesday of
       the two months of each year specified in the applicable pricing
       supplement; or

     - for floating rate notes that reset annually, the third Wednesday of the
       month specified in the applicable pricing supplement.

Regardless of these rules, if a note is originally issued after the regular
record date and before the date that would otherwise be the first interest
payment date, the first interest payment date will be the date that would
otherwise be the second interest payment date. We have defined the term "regular
record date" under "--Payment Mechanics" below.

In addition, the following special provision will apply to a floating rate note
with regard to any interest payment date other than one that falls on the
maturity. If the interest payment date would otherwise fall on a day that is not
a business day, then the interest payment date will be the next day that is a
business day. However, if the floating rate note is a LIBOR note or a EURIBOR
note and the next business day falls in the next calendar month, then the
interest payment date will be advanced to the next preceding day that is a
business day. In all cases, an interest payment date that falls on the maturity
will not be changed.

CALCULATION OF INTEREST
Calculations relating to floating rate notes will be made by the calculation
agent, an institution that we appoint as our agent for this purpose. That
institution may include any affiliate of ours, such as UBS

--------------------------------------------------------------------------------
 162
<PAGE>   195
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

Warburg LLC. The prospectus supplement for a particular floating rate note will
name the institution that we have appointed to act as the calculation agent for
that note as of its original issue date. We may appoint a different institution
to serve as a calculation agent from time to time after the original issue date
of the note without your consent and without notifying you of the change.

For each floating rate note, the calculation agent will determine, on the
corresponding interest calculation or determination date, as described in the
applicable prospectus supplement, the interest rate that takes effect on each
interest reset date. In addition, the calculation agent will calculate the
amount of interest that has accrued during each interest period--i.e., the
period from and including the original issue date, or the last date to which
interest has been paid or made available for payment, to but excluding the
payment date. For each interest period, the calculation agent will calculate the
amount of accrued interest by multiplying the face or other specified amount of
the floating rate note by an accrued interest factor for the interest period.
This factor will be equal to the sum of the interest factors calculated for each
day during the interest period. The interest factor for each day will be
expressed as a decimal and will be calculated by dividing the interest rate,
also expressed as a decimal, applicable to that day:

     - by 360, in the case of commercial paper rate notes, prime rates, LIBOR
       notes, EURIBOR notes, CD rate notes, federal funds rate notes J.J. Kenny
       rate notes and 11th district cost of funds rate notes; or

     - by the actual number of days in the year, in the case of treasury rate
       notes and CMT rate notes.

Upon the request of the Holder of any floating rate note, the calculation agent
will provide for that note the interest rate then in effect--and, if determined,
the interest rate that will become effective on the next interest reset date.
The calculation agent's determination of any interest rate, and its calculation
of the amount of interest for any interest period, will be final and binding in
the absence of manifest error.

All percentages resulting from any calculation relating to a note will be
rounded upward or downward, as appropriate, to the next higher or lower one
hundred-thousandth of a percentage point, e.g., 9.876541% (or .09876541) being
rounded down to 9.87654% (or .0987654), and 9.876545% (or .09876545) being
rounded up to 9.87655% (or .0987655). All amounts used in or resulting from any
calculation relating to a floating rate note will be rounded upward or downward,
as appropriate, to the nearest cent, in the case of U.S. dollars, or to the
nearest corresponding hundredth of a unit, in the case of a currency other than
U.S. dollars, with one-half cent or one-half a corresponding hundredth of a unit
or more being rounded upward.

In determining the base rate that applies to a floating rate note during a
particular interest period, the calculation agent may obtain rate quotes from
various banks or dealers active in the relevant market, as described in the
applicable prospectus supplement. Those reference banks and dealers may include
the calculation agent itself and its affiliates, as well as any underwriter,
dealer, or agent participating in the distribution of the relevant floating rate
notes and its affiliates, and they may include affiliates of UBS.

CALCULATION AGENT.  We have initially appointed UBS Warburg LLC as our
calculation agent for the notes.

COMMERCIAL PAPER RATE NOTES
If you purchase a commercial paper rate note, your note will bear interest at a
base rate equal to the commercial paper rate and adjusted by the spread or
spread multiplier, if any, specified in your prospectus supplement.

                                                                             163

The commercial paper rate will be the MONEY MARKET YIELD of the rate, for the
relevant interest determination date, for commercial paper having the INDEX
MATURITY specified in your prospectus supplement, as published in H.15(519)
under the heading "Commercial Paper -- Nonfinancial." If the commercial paper
rate cannot be determined as described above, the following procedures will
apply.

     - If the rate described above does not appear in H.15 (519) at 3:00 P.M.,
       New York City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from that source at
       that time, then the commercial paper rate will be the rate, for the
       relevant interest determination date, for commercial paper having the
       index maturity specified in your pricing supplement, as published in H.15
       DAILY UPDATE or any other recognized electronic source used for
       displaying that rate, under the heading "Commercial Paper--Nonfinancial."

     - If the rate described above does not appear in H.15(519), H.15 daily
       update or another recognized electronic source at 3:00 P.M., New York
       City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from one of those
       sources at that time, the commercial paper rate will be the money market
       yield of the arithmetic mean of the following offered rates for U.S.
       dollar commercial paper that has the relevant index maturity and is
       placed for an industrial issuer whose bond rating is "AA", or the
       equivalent, from a nationally recognized rating agency: the rates offered
       as of 11:00 A.M., New York City time, on the relevant interest
       determination date, by three leading U.S. dollar commercial paper dealers
       in New York City selected by the calculation agent.

     - If fewer than three dealers selected by the calculation agent are quoting
       as described above, the commercial paper rate for the new interest period
       will be the commercial paper rate in effect for the prior interest
       period. If the initial base rate has been in effect for the prior
       interest period, however, it will remain in effect for the new interest
       period.

PRIME RATE NOTES
If you purchase a prime rate note, your note will bear interest at a base rate
equal to the prime rate as adjusted by the spread or spread multiplier, if any,
specified in your prospectus supplement.

The prime rate will be the rate, for the relevant interest determination date,
published in H.15(519) under the heading "Bank Prime Loan." If the prime rate
cannot be determined as described above, the following procedures will apply.

     - If the rate described above does not appear in H.15(519) at 3:00 P.M.,
       New York City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from that source at
       that time, then the prime rate will be the rate, for the relevant
       interest determination date, as published in H.15 daily update or another
       recognized electronic source used for the purpose of displaying that
       rate, under the heading "Bank Prime Loan."

     - If the rate described above does not appear in H.15(519), H.15 daily
       update or another recognized electronic source at 3:00 P.M., New York
       City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from one of those
       sources at that time, then the prime rate will be the arithmetic mean of
       the following rates as they appear on the REUTERS SCREEN US PRIME 1 PAGE:
       the rate of interest publicly announced by each bank appearing on that
       page as that bank's prime rate or base lending rate, as of 11:00 A.M.,
       New York City time, on the relevant interest determination date.

     - If fewer than four of these rates appear on the Reuters screen US PRIME 1
       page, the prime rate will be the arithmetic mean of the prime rates or
       base lending rates, as of the close of business on the relevant interest
       determination date, of three major banks in New York City selected by

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

       the calculation agent. For this purpose, the calculation agent will use
       rates quoted on the basis of the actual number of days in the year
       divided by a 360-day year.

     - If fewer than three banks selected by the calculation agent are quoting
       as described above, the prime rate for the new interest period will be
       the prime rate in effect for the prior interest period. If the initial
       base rate has been in effect for the prior interest period, however, it
       will remain in effect for the new interest period.

LIBOR NOTES
If you purchase a LIBOR note, your note will bear interest at a base rate equal
to LIBOR, which will be the London interbank offered rate for deposits in U.S.
dollars or any other index currency, as specified in your prospectus supplement.
In addition, the applicable LIBOR base rate will be adjusted by the spread or
spread multiplier, if any, specified in your pricing supplement. LIBOR will be
determined in the following manner:

     - LIBOR will be either:

        -- the offered rate appearing on the TELERATE LIBOR PAGE; or

        -- the arithmetic mean of the offered rates appearing on the REUTERS
           SCREEN LIBOR PAGE unless that page by its terms cites only one rate,
           in which case that rate;

    in either case, as of 11:00 A.M., London time, on the relevant LIBOR
    interest determination date, for deposits of the relevant index currency
    having the relevant index maturity beginning on the relevant interest reset
    date. Your prospectus supplement will indicate the index currency, the index
    maturity and the reference page that will apply to your LIBOR note. If no
    reference page is specified in your prospectus supplement, Telerate LIBOR
    page will apply to your LIBOR note.

     - If the Telerate LIBOR page applies and the rate described above does not
       appear on that page, or if Reuters screen LIBOR page applies and fewer
       than two of the rates described above appears on that page or no rate
       appears on any page on which only one rate normally appears, then LIBOR
       will be determined on the basis of the rates, at approximately 11:00
       A.M., London time, on the relevant LIBOR interest determination date, at
       which deposits of the following kind are offered to prime banks in the
       London interbank market by four major banks in that market selected by
       the calculation agent: deposits of the index currency having the relevant
       index maturity, beginning on the relevant interest reset date, and in a
       REPRESENTATIVE AMOUNT. The calculation agent will request the principal
       London office of each of these banks to provide a quotation of its rate.
       If at least two quotations are provided, LIBOR for the relevant LIBOR
       interest determination date will be the arithmetic mean of the
       quotations.

     - If fewer than two quotations are provided as described above, LIBOR for
       the relevant LIBOR interest determination date will be the arithmetic
       mean of the rates for loans of the following kind to leading European
       banks quoted, at approximately 11:00 A.M., in the principal financial
       center for the country of the index currency, on that LIBOR interest
       determination date, by three major banks in that financial center
       selected by the calculation agent: loans of the index currency having the
       relevant index maturity, beginning on the relevant interest reset date,
       and in a representative amount.

     - If fewer than three banks selected by the calculation agent are quoting
       as described above, LIBOR for the new interest period will be LIBOR in
       effect for the prior interest period. If the initial base rate has been
       in effect for the prior interest period, however, it will remain in
       effect for the new interest period.

EURIBOR NOTES
If you purchase a EURIBOR note, your note will bear interest at a base rate
equal to the interest rate for deposits in euros designated as "EURIBOR" and
sponsored jointly by the European Banking Federation and ACI--the Financial
Market Association, or any company established by the joint sponsors for
purposes of compiling and publishing that rate. In addition, the EURIBOR base
rate will be adjusted by the spread or spread multiplier, if any, specified in
your prospectus supplement. EURIBOR will be determined in the following manner:

     - EURIBOR will be the offered rate for deposits in euros having the index
       maturity specified in your pricing supplement, beginning on the second
       euro business day after the relevant EURIBOR interest determination date,
       as that rate appears on TELERATE PAGE 248 as of 11:00 A.M., Brussels
       time, on the relevant EURIBOR interest determination date.

     - If the rate described above does not appear on Telerate page 248, EURIBOR
       will be determined on the basis of the rates, at approximately 11:00
       A.M., Brussels time, on the relevant EURIBOR interest determination date,
       at which deposits of the following kind are offered to prime banks in the
       EURO-ZONE interbank market by the principal euro-zone office of each of
       four major banks in that market selected by the calculation agent: euro
       deposits having the relevant index maturity, beginning on the relevant
       interest reset date, and in a representative amount. The calculation
       agent will request the principal euro-zone office of each of these banks
       to provide a quotation of its rate. If at least two quotations are
       provided, EURIBOR for the relevant EURIBOR interest determination date
       will be the arithmetic mean of the quotations.

     - If fewer than two quotations are provided as described above, EURIBOR for
       the relevant EURIBOR interest determination date will be the arithmetic
       mean of the rates for loans of the following kind to leading euro-zone
       banks quoted, at approximately 11:00 A.M., Brussels time on that EURIBOR
       interest determination date, by three major banks in the euro-zone
       selected by the calculation agent: loans of euros having the relevant
       index maturity, beginning on the relevant interest reset date, and in a
       representative amount.

     - If fewer than three banks selected by the calculation agent are quoting
       as described above, EURIBOR for the new interest period will be EURIBOR
       in effect for the prior interest period, If the initial base rate has
       been in effect for the prior interest period, however, it will remain in
       effect for the new interest period.

TREASURY RATE NOTES
If you purchase a treasury rate note, your note will bear interest at a base
rate equal to the treasury rate and adjusted by the spread or spread multiplier,
if any, specified in your prospectus supplement.

The treasury rate will be the rate for the auction, on the relevant treasury
interest determination date, of treasury bills having the index maturity
specified in your pricing supplement, as that rate appears on Telerate page 56
or 57 under the heading "Investment Rate". If the treasury rate cannot be
determined in this manner, the following procedures will apply.

     - If the rate described above does not appear on either page at 3:00 P.M.,
       New York City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from that source at
       that time, the treasury rate will be the BOND EQUIVALENT YIELD of the
       rate, for the relevant interest determination date, for the type of
       treasury bill described above, as published in H.15 daily update, or
       another recognized electronic source used for displaying that rate, under
       the heading "U.S. Government Securities/Treasury Bills/Auction High".

     - If the rate described in the prior paragraph does not appear in H.15
       daily update or another recognized electronic source at 3:00 P.M., New
       York City time, on the relevant interest

DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

       calculation date, unless the calculation is made earlier and the rate is
       available from one of those sources at that time, the treasury rate will
       be the bond equivalent yield of the auction rate, for the relevant
       treasury interest determination date and for treasury bills of the kind
       described above, as announced by the U.S. Department of the Treasury.

     - If the auction rate described in the prior paragraph is not so announced
       by 3:00 P.M., New York City time, on the relevant interest calculation
       date, or if no such auction is held for the relevant week, then the
       treasury rate will be the bond equivalent yield of the rate, for the
       relevant treasury interest determination date and for treasury bills
       having a remaining maturity closest to the specified index maturity, as
       published in H.15(519) under the heading "U.S. Government
       Securities/Treasury Bills/Secondary Market".

     - If the rate described in the prior paragraph does not appear in H.15(519)
       at 3:00 P.M., New York City time, on the relevant interest calculation
       date, unless the calculation is made earlier and the rate is available
       from one of those sources at that time, then the treasury rate will be
       the rate, for the relevant treasury interest determination date and for
       treasury bills having a remaining maturity closest to the specified index
       maturity, as published in H.15 daily update, or another recognized
       electronic source used for displaying that rate, under the heading "U.S.
       Government Securities/Treasury Bills/Secondary Market".

     - If the rate described in the prior paragraph does not appear in H.15
       daily update or another recognized electronic source at 3:00 P.M., New
       York City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from one of those
       sources at that time, the treasury rate will be the bond equivalent yield
       of the arithmetic mean of the following secondary market bid rates for
       the issue of treasury bills with a remaining maturity closest to the
       specified index maturity: the rates bid as of approximately 3:30 P.M.,
       New York City time, on the relevant treasury interest determination date,
       by three primary U.S. government securities dealers in New York City
       selected by the calculation agent.

     - If fewer than three dealers selected by the calculation agent are quoting
       as described in the prior paragraph, the treasury rate in effect for the
       new interest period will be the treasury rate in effect for the prior
       interest period. If the initial base rate has been in effect for the
       prior interest period, however, it will remain in effect for the new
       interest period.

CMT RATE NOTES
If you purchase a CMT rate note, your note will bear interest at a base rate
equal to the CMT rate and adjusted by the spread or spread multiplier, if any,
specified in your prospectus supplement.

The CMT rate will be the following rate displayed on the DESIGNATED CMT TELERATE
PAGE under the heading "... Treasury Constant Maturities. . . Federal Reserve
Board Release H.15 . . . Mondays Approximately 3:45 P.M.", under the column for
the DESIGNATED CMT INDEX MATURITY:

     - if the designated CMT Telerate page is Telerate page 7051, the rate for
       the relevant interest determination date; or

     - if the designated CMT Telerate page is Telerate page 7052, the weekly or
       monthly average, as specified in your prospectus supplement, for the week
       that ends immediately before the week in which the relevant interest
       determination date falls, or for the month that ends immediately before
       the month in which the relevant interest determination date falls, as
       applicable.

If the CMT rate cannot be determined in this manner, the following procedures
will apply.

     - If the applicable rate described above is not displayed on the relevant
       designated CMT Telerate page at 3:00 P.M., New York City time, on the
       relevant interest calculation date, unless the

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

       calculation is made earlier and the rate is available from that source at
       that time, then the CMT rate will be the applicable treasury constant
       maturity rate described above--i.e., for the designated CMT index
       maturity and for either the relevant interest determination date or the
       weekly or monthly average, as applicable --as published in H.15 (519).

     - If the applicable rate described above does not appear in H.15 (519) at
       3:00 P.M., New York City time, on the relevant interest calculation date,
       unless the calculation is made earlier and the rate is available from one
       of those sources at that time, then the CMT rate will be the treasury
       constant maturity rate, or other U.S. treasury rate, for the designated
       CMT index maturity and with reference to the relevant interest
       determination date, that:

        -- is published by the Board of Governors of the Federal Reserve System,
           or the U.S. Department of the Treasury; and

        -- is determined by the calculation agent to be comparable to the
           applicable rate formerly displayed on the designated CMT Telerate
           page and published in H.15 (519).

     - If the rate described in the prior paragraph does not appear at 3:00
       P.M., New York City time, on the relevant interest calculation date,
       unless the calculation is made earlier and the rate is available from one
       of those sources at that time, then the CMT rate will be the yield to
       maturity of the arithmetic mean of the following secondary market offered
       rates for the most recently issued treasury notes having an original
       maturity of approximately the designated CMT index maturity and a
       remaining term to maturity of not less than the designated CMT index
       maturity minus one year, and in a representative amount: the offered
       rates, as of approximately 3:30 P.M., New York City time, on the relevant
       interest determination date, of three primary U.S. government securities
       dealers in New York City selected by the calculation agent. In selecting
       these offered rates, the calculation agent will request quotations from
       five of these primary dealers and will disregard the highest
       quotation--or, if there is equality, one of the highest--and the lowest
       quotation--or, if there is equality, one of the lowest. Treasury notes
       are direct, non-callable, fixed rate obligations of the U.S. government.

     - If the calculation agent is unable to obtain three quotations of the kind
       described in the prior paragraph, the CMT rate will be the yield to
       maturity of the arithmetic mean of the following secondary market offered
       rates for treasury notes with an original maturity longer than the
       designated CMT index maturity, with a remaining term to maturity closest
       to the designated CMT index maturity and in a representative amount: the
       offered rates, as of approximately 3:30 P.M., New York City time, on the
       relevant interest determination date, of three primary U.S. government
       securities dealers in New York City selected by the calculation agent. In
       selecting these offered rates, the calculation agent will request
       quotations from five of these primary dealers and will disregard the
       highest quotation--or, if there is equality, one of the highest--and the
       lowest quotation--or, if there is equality, one of the lowest. If two
       treasury notes with an original maturity longer than the designated CMT
       index maturity have remaining terms to maturity that are equally close to
       the designated CMT index maturity, the calculation agent will obtain
       quotations for the treasury note with the shorter remaining term to
       maturity.

     - If fewer than five but more than two of these primary dealers are quoting
       as described in the prior paragraph, then the CMT rate for the relevant
       interest determination date will be based on the arithmetic mean of the
       offered rates so obtained, and neither the highest nor the lowest of
       those quotations will be disregarded.

     - If two or fewer primary dealers selected by the calculation agent are
       quoting as described above, the CMT rate in effect for the new interest
       period will be the CMT rate in effect for the prior

       interest period. If the initial base rate has been in effect for the
       prior interest period, however, it will remain in effect for the new
       interest period.

CD RATE NOTES
If you purchase a CD rate note, your note will bear interest at a base rate
equal to the CD rate and adjusted by the spread or spread multiplier, if any,
specified in your prospectus supplement.

The CD rate will be the rate, on the relevant interest determination date, for
negotiable U.S. dollar certificates of deposit having the index maturity
specified in your prospectus supplement, as published in H.15 (519) under the
heading "CDs (Secondary Market)". If the CD rate cannot be determined in this
manner, the following procedures will apply.

     - If the rate described above does not appear in H.15 (519) at 3:00 P.M.,
       New York City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from that source at
       that time, then the CD rate will be the rate, for the relevant interest
       determination date, described above as published in H.15 daily update, or
       another recognized electronic source used for displaying that rate, under
       the heading "CDs (Secondary Market)".

     - If the rate described above does not appear in H.15 (519), H.15 daily
       update or another recognized electronic source at 3:00 P.M., New York
       City time, on the relevant interest calculation date, unless the
       calculation is made earlier and the rate is available from one of those
       sources at that time, the CD rate will be the arithmetic mean of the
       following secondary market offered rates for negotiable U.S. dollar
       certificates of deposit of major U.S. money center banks with a remaining
       maturity closest to the specified index maturity, and in a representative
       amount: the rates offered as of 10:00 A.M., New York City time, on the
       relevant interest determination date, by three leading nonbank dealers in
       negotiable U.S. dollar certificates of deposit in New York City, as
       selected by the calculation agent.

     - If fewer than three dealers selected by the calculation agent are quoting
       as described above, the CD rate in effect for the new interest period
       will be the CD rate in effect for the prior interest period. If the
       initial base rate has been in effect for the prior interest period,
       however, it will remain in effect for the new interest period.

FEDERAL FUNDS RATE NOTES
If you purchase a federal funds rate note, your note will bear interest at a
base rate equal to the federal funds rate and adjusted by the spread or spread
multiplier, if any, specified in your prospectus supplement.

The federal funds rate will be the rate for U.S. dollar federal funds on the
relevant interest determination date, as published in H.15 (519) under the
heading "Federal Funds (Effective)", as that rate is displayed on Telerate page
120. If the federal funds rate cannot be determined in this manner, the
following procedures will apply.

     - If the rate described above is not displayed on Telerate page 120 at 3:00
       P.M., New York City time, on the relevant interest calculation date,
       unless the calculation is made earlier and the rate is available from
       that source at that time, then the federal funds rate, for the relevant
       interest determination date, will be the rate described above as
       published in H.15 daily update, or another recognized electronic source
       used for displaying that rate, under the heading "Federal Funds
       (Effective)".

     - If the rate described above is not displayed on Telerate page 120 and
       does not appear in H.15 (519), H.15 daily update or another recognized
       electronic source at 3:00 P.M., New York City

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

       time, on the relevant interest calculation date, unless the calculation
       is made earlier and the rate is available from one of those sources at
       that time, the federal funds rate will be the arithmetic mean of the
       rates for the last transaction in overnight, U.S. dollar federal funds
       arranged, before 9:00 A.M., New York City time, on the relevant interest
       determination date, by three leading brokers of U.S. dollar federal funds
       transactions in New York City selected by the calculation agent.

     - If fewer than three brokers selected by the calculation agent are quoting
       as described above, the federal funds rate in effect for the new interest
       period will be the federal funds rate in effect for the prior interest
       period. If the initial base rate has been in effect for the prior
       interest period, however, it will remain in effect for the new interest
       period.

J.J. KENNY RATE NOTES
If you purchase a J.J. Kenny rate note, your note will bear interest at a base
rate equal to the high grade weekly index made available by J.J. Kenny
Information Systems, which we call the weekly index, adjusted by the spread or
spread multiplier, if any, specified in your prospectus supplement.

The J.J. Kenny rate will be the rate on the relevant interest determination date
equal to the weekly index. J.J. Kenny formulates the weekly index by selecting
at least five high grade component issuers, including issuers of general
obligation bonds. The weekly index includes the 30 day yield evaluations at par
of bonds of these selected issuers. J.J. Kenny may change the issuers from time
to time at its discretion. J.J. Kenny will select only bonds that are exempt
from Federal income taxation under the Internal Revenue Code. J.J. Kenny will
not select bonds on which the interest is subject to a minimum tax or similar
tax under the Internal Revenue Code unless all tax-exempt bonds are subject to
such a tax.

If J.J. Kenny stops making the weekly index available, the calculation agent
will select a new indexing agent. The index made available by the new indexing
agent will reflect the prevailing rate for bonds rated in the highest short-term
rating category by Moody's Investors Service, Inc. and Standard & Poor's Rating
Services from issuers most closely resembling the high grade component issuers
selected by J.J. Kenny. The interest on the bonds selected by the new indexing
agent will be variable on a weekly basis, exempt from federal income taxation
and not subject to a minimum tax unless all tax exempt bonds are subject to a
minimum tax. If a new indexing agent is not available to replace J.J. Kenny,
then the J.J. Kenny rate will be 67% of the Treasury Rate.

11TH DISTRICT COST OF FUNDS RATE NOTES
If you purchase an 11th district cost of funds rate note, your note will bear
interest at a base rate equal to the 11th district cost of funds rate and
adjusted by the spread or spread multiplier, if any, specified in your
prospectus supplement.

The 11th district cost of funds rate will be the rate equal to the monthly
weighted average cost of funds for the calendar month immediately before the
relevant 11th district interest determination date, as displayed on Telerate
page 7058 under the heading "11th District" as of 11:00 A.M., San Francisco
time, on that date. If the 11th district cost of funds rate cannot be determined
in this manner, the following procedures will apply.

     - If the rate described above does not appear on Telerate page 7058 on the
       relevant 11th district interest determination date, then the 11th
       district cost of funds rate for that date will be the monthly weighted
       average cost of funds paid by institutions that are members of the
       Eleventh Federal Home Loan Bank District for the calendar month
       immediately before the relevant 11th district interest determination
       date, as most recently announced by the Federal Home Loan Bank of San
       Francisco as that cost of funds.

     - If the Federal Home Loan Bank of San Francisco fails to announce the cost
       of funds described in the prior paragraph on or before the relevant 11th
       district interest determination date, the 11th district cost of funds
       rate in effect for the new interest period will be the 11th district cost
       of funds rate in effect for the prior interest period. If the initial
       base rate has been in effect for the prior interest period, however, it
       will remain in effect for the new interest period.

RENEWABLE FLOATING RATE NOTES
If specified in the applicable prospectus supplement, your floating rate note
may be a renewable floating rate note. The interest rate and other relevant
terms of your renewable floating rate note will be described in the applicable
prospectus supplement.

Renewable floating rate notes will mature as described in the applicable
prospectus supplement unless the stated maturity of all or a portion of the
principal amount is extended in the following manner. The interest payment dates
in May and November of each year, or in the months specified in the applicable
prospectus supplement, will be the election dates. On each election date, the
maturity of your renewable floating rate note will be automatically extended to
the interest payment date occurring twelve months after the election date,
unless the Holder elects to terminate the automatic extension. The Holder may
elect to terminate the automatic extension either as to the entire maturity or
as to any portion of the maturity having a principal amount of US$1,000 or any
multiple of US$1,000 (or, in the case of a note denominated in a currency other
than dollars, a principal amount or multiple as described in the applicable
prospectus supplement). To make this election, the Holder must give notice to
the paying agent within the time frame specified in the applicable prospectus
supplement. If the Holder elects to terminate the automatic extension as to the
whole or any portion of the maturity, that whole or portion will become due and
payable on the interest payment date falling six months after the election date
that preceded the election date on which the Holder made the election, or at
such time as specified in the applicable prospectus supplement. The applicable
prospectus supplement will also specify a final maturity date, beyond which
there will be no automatic extension.

The Holder of a renewable floating rate note may revoke an election to terminate
the automatic extension of the entire amount as to which the election was made,
or any portion of that amount having a principal amount of US$1,000 or any
multiple of US$1,000 (or, in the case of a note denominated in a currency other
than dollars, a principal amount or multiple as described in the applicable
prospectus supplement). To revoke an election, the Holder must deliver notice to
the paying agent on any day following the election but no later than 15 days
before the revoked portion would otherwise mature, or at such time as specified
in the applicable prospectus supplement. A revocation may not be made, however,
during the period between and including a record date and the immediately
succeeding interest payment date.

An election to terminate the automatic extension, if not revoked in the manner
described immediately above by the Holder or any subsequent Holder, will be
binding upon any subsequent Holder.

We may redeem a renewable floating rate note in whole or in part on the interest
payment dates in each year specified in the applicable prospectus supplement, at
a redemption price set forth in the applicable prospectus supplement, together
with accrued interest to the date of the redemption. If we redeem a renewable
floating rate note, we will mail notice of the redemption to each Holder by
first class mail, postage-prepaid, at least 180 days before the date selected
for the redemption. We will follow this procedure even if it differs from any
procedure specified under "--Redemption and Repayment" below.

SPECIAL RATE CALCULATION TERMS
In this subsection entitled "--Interest Rates," we use several terms that have
special meanings relevant to calculating floating interest rates. We define
these terms as follows:

The term "BOND EQUIVALENT YIELD" means a yield expressed as a percentage and
calculated in accordance with the following formula:

                                D x N
bond equivalent yield =  ------------------   X 100
                            360 - (D x M)
</TABLE>

     where

     - "D" means the annual rate for treasury bills quoted on a bank discount

designated CMT index maturity will be 2 years.

The term "DESIGNATED CMT TELERATE PAGE" means the Telerate page specified in the
applicable prospectus supplement that displays treasury constant maturities as
reported in H.15 (519). If no Telerate page is so specified, then the applicable

                               D x 360
money market yield =     ------------------   X 100

EXTENSION OF MATURITY

If specified in the applicable prospectus supplement, we will have the option to
extend the stated maturity for one or more periods of whole years up to but not
beyond the final maturity date specified in the prospectus supplement. We call a
note whose maturity we may extend an extendible note. We call the period of time
as to which we may extend the maturity the extension period. The following

--------------------------------------------------------------------------------
                                                                             173
<PAGE>   206
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

procedures will apply to extendible notes, unless otherwise indicated in the
applicable prospectus supplement.

We may extend the maturity of an extendible note by notifying the paying agent
between 45 and 60 days before the stated maturity then in effect. The stated
maturity may be the original stated maturity, as described in the prospectus
supplement, or a maturity that we previously extended by following these
procedures. If we notify the paying agent that we will extend the maturity, the
paying agent will send a notice to each Holder by first class mail, postage
prepaid, or by other means agreed upon between us and the paying agent, at least
30 days before the stated maturity then in effect. The notice sent by the paying
agent will set forth the following information:

     - the company's election to extend the maturity of the extendible note.

     - the extended maturity date or, if the maturity date had previously been
       extended, the new extended maturity date.

     - the interest rate that will apply during the extension period or, in the
       case of a floating rate note, the spread and/or spread multiplier, if
       any, applicable during the extension period.

     - the provisions, if any, for redemption and repayment during the extension
       period.

Once the paying agent has mailed the notice to each Holder, the extension of the
maturity date will take place automatically. All of the terms of the note will
be the same as the terms of the note as originally issued, except those terms
that are described in the notice sent by the paying agent to each Holder and
except as described in the following paragraph.

Not later than 10:00 a.m., New York City time, on the twentieth calendar day
before the maturity date then in effect for an extendible note or, if that day
is not a business day, on the next succeeding business day, we may revoke the
interest rate set forth in the extension notice sent by the paying agent to each
Holder and establish a higher interest rate for the extension period. If we
elect to establish a higher interest rate, the paying agent will send a notice
to each Holder by first class mail, postage prepaid, or by other means agreed
between us and the paying agent, of the higher interest rate in the case of a
floating rate note, the higher spread and/or spread multiplier, if any. The
notice of the higher rate cannot be revoked. All extendible notes as to which
the maturity date has been extended will bear the higher rate for the extension
period, whether or not tendered for repayment.

If we elect to extend the maturity date of an extendible note, each Holder may
elect repayment of all or part of its note on the maturity date then in effect
at a price equal to the principal amount plus any accrued and unpaid interest to
that date. To elect repayment, a Holder must give notice to the paying agent
between 25 and 35 days before the maturity date in effect. The notice must
consist of either:

     - the note along with the completed form entitled "Option to Elect
       Repayment," which is attached to your note.

     - a telegram, facsimile transmission or letter from a member of a national
       securities exchange, the National Association of Securities Dealers, Inc.
       or a commercial bank or trust company in the United States setting forth
       the name of the Holder, the principal amount of the note, the principal
       amount of the note to be repaid, the certificate number or a description
       of the tenor and terms of the note, a statement that the option to elect
       repayment is being elected and a guarantee that the note, together with
       the completed form entitled "Option to Elect Repayment" will be received
       by the paying agent no later than the fifth business day after the date
       of the telegram, facsimile transmission or letter. The telegram,
       facsimile transmission or letter will become effective upon receipt, by
       that fifth business day, of the note and complete form.

--------------------------------------------------------------------------------
 174
<PAGE>   207
DESCRIPTION OF NOTES WE MAY OFFER

The Holder may revoke the election of repayment by sending to the paying agent
written notice by 3:00 p.m., New York City time, on the twentieth day before the
maturity date then in effect or, if that day is not a business day, on the next
succeeding business day.

REDEMPTION AND REPAYMENT

Unless otherwise indicated in your prospectus supplement, your note will not be
entitled to the benefit of any sinking fund--that is, we will not deposit money
on a regular basis into any separate custodial account to repay your notes. In
addition, we will not be entitled to redeem your note before its stated maturity
(except for certain tax reasons, as described below) unless your prospectus
supplement specifies a redemption date or redemption commencement date. You will
not be entitled to require us to buy your note from you, before its stated
maturity, unless your prospectus supplement specifies one or more repayment
dates.

If your prospectus supplement specifies one or more redemption dates, a
redemption commencement date or a repayment date, it will also specify one or
more redemption prices or repayment prices, which will be expressed as a
percentage of the principal amount of your debt security. It may also specify
one or more redemption periods during which the redemption prices relating to a
redemption of notes during those periods will apply.

If your prospectus supplement specifies one or more redemption dates, your note
will be redeemable on any of those dates. If your prospectus supplement
specifies a redemption commencement date, your note will be redeemable at our
option at any time on or after that date. If we redeem your note, we will do so
at the specified redemption price. If different prices are specified for
different redemption periods, the price we pay will be the price that applies to
the redemption period during which your note is redeemed.

If your prospectus supplement specifies a repayment date, your note will be
repayable at your option on the specified repayment date at the specified
repayment price, together with interest accrued to the repayment date.

If we exercise an option to redeem any note, we will give the trustee and the
Holders written notice of the principal amount of the note to be redeemed, not
less than 10 days nor more than 60 days before the applicable redemption date.
We will give the notice in the manner described below in "--Notices."

If a note represented by a global note is subject to repayment at the Holder's
option, the depositary or its nominee, as the Holder, will be the only person
that can exercise the right to repayment. Any indirect holders who own
beneficial interests in the global note and wish to exercise a repayment right
must give proper and timely instructions to their banks or brokers through which
they hold their interests, requesting that they notify the depositary to
exercise the repayment right on their behalf. Different firms have different
deadlines for accepting instructions from their customers, and you should take
care to act promptly enough to ensure that your request is given effect by the
depositary before the applicable deadline for exercise.

Street name and other indirect holders should contact their banks or brokers for
information about how to exercise a repayment right in a timely manner.

If the option of the Holder to elect repayment is deemed to be a "tender offer"
within the meaning of Rule 14e-1 under the Securities Exchange Act of 1934, we
will comply with Rule 14e-1 as then in effect to the extent applicable.

We or our affiliates may purchase notes from investors who are willing to sell
from time to time, either in the open market at prevailing prices or in private
transactions at negotiated prices. Notes that we or they purchase may, at our
discretion, be held, resold or cancelled.

<PAGE>   208
DESCRIPTION OF NOTES WE MAY OFFER

OPTIONAL TAX REDEMPTION

In addition to the situations described above under "-- Redemption and
Repayment," we also have the option to redeem the notes in two situations
described below, unless otherwise indicated in your prospectus supplement. The
redemption price for the notes, other than original issue discount notes, will
be equal to the principal amount of the notes being redeemed plus accrued
interest and any additional amounts due on the date fixed for redemption. The
redemption price for original issue discount notes will be specified in the
prospectus supplement for such notes. Furthermore, we must give you between 10
and 60 days' notice before redeeming the notes.

     - The first situation is where, as a result of a change in, execution of or
       amendment to any laws or treaties or the official application or
       interpretation of any laws or treaties, we would be required to pay
       additional amounts as described below under "Payment of Additional
       Amounts."

       This applies only in the case of changes, executions, amendments,
       applications or interpretations that occur on or after the date specified
       in the prospectus supplement for the applicable notes and in a relevant
       jurisdiction, as defined in "-- Payment of Additional Amounts" below. If
       UBS is succeeded by another entity, the applicable jurisdiction will be
       the jurisdiction in which the successor entity is organized, and the
       applicable date will be the date the entity became a successor.

       We would not have the option to redeem in this case if we could have
       avoided the payment of additional amounts or the deduction or withholding
       by using reasonable measures available to us.

     - The second situation is where a person located outside of a relevant
       jurisdiction into which UBS is merged or to whom it has conveyed,
       transferred or leased its property is required to pay an additional
       amount. We would have the option to redeem the notes even if we are
       required to pay additional amounts immediately after the merger,
       conveyance, transfer or lease. We are not required to use reasonable
       measures to avoid the obligation to pay additional amounts in this
       situation.

PAYMENT OF ADDITIONAL AMOUNTS

A relevant jurisdiction may require UBS to withhold amounts from payments on the
principal or interest on a note for taxes or any other governmental charges. If
the relevant jurisdiction requires a withholding of this type, UBS may be
required to pay you an additional amount so that the net amount you receive will
be the amount specified in the note to which you are entitled.

By relevant jurisdiction, we mean Switzerland or a jurisdiction in which the UBS
branch through which notes are issued is located. UBS will NOT have to pay
additional amounts in respect of taxes or other governmental charges that are
required to be deducted or withheld by any paying agent from a payment on a
note, if such payment can be made without such deduction or withholding by any
other paying agent, or in respect of taxes or other governmental charges that
would not have been imposed but for

     - the existence of any present or former connection between you and the
       relevant jurisdiction, other than the mere holding of the note and the
       receipt of payments on it;

     - your status as an individual resident of a member state of the European
       Union;

     - a failure to comply with any reasonable certification, documentation,
       information or other reporting requirement concerning your nationality,
       residence, identity or connection with the relevant jurisdiction, if such
       compliance is required as a precondition to relief or exemption

--------------------------------------------------------------------------------
 176
<PAGE>   209
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

       from such taxes or other governmental charges (including, without
       limitation, a certification that you are not resident in the relevant
       jurisdiction or are not an individual resident of a member state of the
       European Union); or

     - a change in law that becomes effective more than 30 days after a payment
       on the note becomes due and payable or on which the payment is duly
       provided for, whichever occurs later.

These provisions will also apply to any taxes or governmental charges imposed by
any jurisdiction in which a successor to UBS is organized. The prospectus
supplement relating to the note may describe additional circumstances in which
UBS would not be required to pay additional amounts.

MERGERS AND SIMILAR TRANSACTIONS

We are generally permitted to merge or consolidate with another firm. We are
also permitted to sell substantially all our assets to another firm. We may not
take any of these actions, however, unless all the following conditions are met:

     - If the successor firm in the transaction is not UBS, the successor firm
       must be organized as a corporation, partnership, trust, limited liability
       company or other similar entity and must expressly assume UBS's
       obligations under the notes and the indenture. The successor firm may be
       organized under the laws of any jurisdiction, whether in Switzerland or
       elsewhere.

     - Immediately after the transaction, no default under the notes has
       occurred and is continuing. For this purpose, "default under the notes"
       means an event of default or any event that would be an event of default
       if the requirements for giving us default notice and for our default
       having to continue for a specific period of time were disregarded. We
       describe these matters below under "--Default, Remedies and Waiver of
       Default."

If the conditions described above are satisfied, we will not need to obtain the
approval of the Holders in order to merge or consolidate or to sell all or
substantially all our assets. Also, these conditions will apply only if we wish
to merge or consolidate with another firm or sell all or substantially all our
assets. We will not need to satisfy these conditions if we enter into other
types of transactions, including any transaction in which we acquire the stock
or assets of another firm, any transaction that involves a change of control of
UBS but in which we do not merge or consolidate and any transaction in which we
sell less than substantially all our assets.

Also, if we merge, consolidate or sell all or substantially all of our assets
and the successor firm is a non-Swiss entity, neither we nor any successor would
have any obligation to compensate you for any resulting adverse tax consequences
to the notes.

DEFEASANCE AND COVENANT DEFEASANCE

Unless we say otherwise in the applicable prospectus supplement, the provisions
for full defeasance and covenant defeasance described below apply to each note
as indicated in the applicable prospectus supplement. In general, we expect
these provisions to apply to each note that is not a floating rate note, equity
or credit indexed note or credit linked note and that has a specified currency
of U.S. dollars.

--------------------------------------------------------------------------------
                                                                             177
<PAGE>   210
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

FULL DEFEASANCE.  If there is a change in U.S. federal tax law, as described
below, we can legally release ourselves from all payment and other obligations
on your note. This is called full defeasance. To do so, each of the following
must occur:

     - We must deposit in trust for the benefit of all Holders a combination of
       money and U.S. government or U.S. government agency notes or bonds that
       will generate enough cash to make interest, principal and any other
       payments on your note on their various due dates.

     - There must be a change in current U.S. federal tax law or an Internal
       Revenue Service ruling that lets us make the above deposit without
       causing you to be taxed on your note any differently than if we did not
       make the deposit and just repaid the note ourselves. Under current
       federal tax law, the deposit and our legal release from the note would be
       treated as though we took back your note and gave you your share of the
       cash and notes or bonds deposited in trust. In that event, you could
       recognize gain or loss on your note.

     - We must deliver to the trustee a legal opinion of our counsel confirming
       the tax law change described above.

If we ever fully defease your note, you will have to rely solely on the trust
deposit for payments on your note. You could not look to us for payment in the
event of any shortfall.

COVENANT DEFEASANCE.  Under current U.S. federal tax law, we can make the same
type of deposit described above and be released from certain restrictive
covenants relating to your note. This is called covenant defeasance. In that
event, you would lose the protection of those restrictive covenants. In order to
achieve covenant defeasance, we must do both of the following:

     - We must deposit in trust for the benefit of all Holders a combination of
       money and U.S. government or U.S. government agency notes or bonds that
       will generate enough cash to make interest, principal and any other
       payments on your note on their various due dates.

     - We must deliver to the trustee a legal opinion of our counsel confirming
       that under U.S. federal income tax law as then in effect we may make the
       above deposit without causing you to be taxed on your note any
       differently than if we did not make the deposit and just repaid the note
       ourselves.

If we accomplish covenant defeasance with regard to your note, the events of
default resulting from a breach of covenants, described below in the fourth item
under "-- Default, Remedies and Waiver of Default -- Events of Default" would no
longer apply

If we accomplish covenant defeasance, you can still look to us for repayment of
your note in the event of any shortfall in the trust deposit. You should note,
however, that if one of the remaining events of default occurred, such as our
bankruptcy, and your note became immediately due and payable, there may be a
shortfall. Depending on the event causing the default you may not be able to
obtain payment of the shortfall.

DEFAULT, REMEDIES AND WAIVER OF DEFAULT

You will have special rights if an event of default with respect to your note
occurs and is not cured, as described in this subsection.

EVENTS OF DEFAULT
With respect to your note, when we refer to an event of default, we mean any of
the following:

     - We do not pay the principal or any premium (including any security or
       other property deliverable) on any Series A medium-term note on its
       stated maturity;

--------------------------------------------------------------------------------
 178
<PAGE>   211
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

     - We do not pay interest on any Series A medium-term note within 30 days
       after its due date;

     - We do not deposit a sinking fund payment with regard to any Series A
       medium-term note on its due date, but only if the payment is required in
       the applicable prospectus supplement;

     - We remain in breach of any covenant we make in the indenture for the
       benefit of the Series A medium-term notes, for 60 days after we receive a
       notice of default stating that we are in breach. The notice must be sent
       by the trustee or the Holders of not less than 10% in principal amount of
       the debt securities;

     - We file for bankruptcy or certain other bankruptcy, insolvency or
       reorganization events relating to UBS occur; or

     - If your prospectus supplement states that any additional event of default
       applies to your note, that event of default occurs.

REMEDIES IF AN EVENT OF DEFAULT OCCURS
If an event of default has occurred and has not been cured or waived, the
trustee or the Holders of not less than 25% in principal amount of all Series A
medium-term notes may declare the entire principal amount of all the Series A
medium-term notes to be due immediately. If an event of default occurs because
of bankruptcy, insolvency or reorganization events relating to UBS, the entire
principal amount of all the notes will be automatically accelerated, without any
action by the trustee or any Holder.

The acceleration of any notes as described above is called an acceleration of
the maturity of the affected notes. If the maturity of any notes is accelerated
and a judgment for payment has not yet been obtained, the Holders of a majority
in principal amount of the notes affected by the acceleration may cancel the
acceleration for all the affected notes.

If an event of default occurs, the trustee will have special duties. The trustee
will be obligated to use those of its rights and powers under the indenture, and
to use the same degree of care and skill in doing so, that a prudent person
would use in that situation in conducting his or her own affairs.

Except as described in the prior paragraph, the trustee is not required to take
any action under the indenture at the request of any Holders unless the Holders
offer the trustee reasonable protection from expenses and liability. This is
called an indemnity. If the trustee is provided with an indemnity reasonably
satisfactory to it, the Holders of a majority in principal amount of all Series
A medium-term notes may direct the time, method and place of conducting any
lawsuit or other formal legal action seeking any remedy available to the
trustee. These majority Holders may also direct the trustee in performing any
other action under the indenture with respect to the Series A medium-term notes.

Before you bypass the trustee and bring your own lawsuit or other formal legal
action or take other steps to enforce your rights or protect your interests
relating to the notes, the following must occur:

     - The Holder of your note must give the trustee written notice that an
       event of default has occurred, and the event of default must not have
       been cured or waived.

     - The Holders of not less than 25% in principal amount of all Series A
       medium-term notes must make a written request that the trustee take
       action because of the default, and they or other Holders must offer to
       the trustee indemnity reasonably satisfactory to the trustee against the
       cost and other liabilities of taking that action.

     - The trustee must not have taken action for 60 days after the above steps
       have been taken.

     - During those 60 days, the Holders of a majority in principal amount of
       the Series A medium-term notes must not have given the trustee directions
       that are inconsistent with the written

       request of the Holders of not less than 25% in principal amount of all
       Series A medium-term notes.

You are, however, entitled at any time to bring a lawsuit for the payment of
money due on your note on or after its due date.

WAIVER OF DEFAULT
The Holders of not less than a majority in principal amount of the Series A
medium-term notes as to which a default occurred may waive a default for those
Series A medium-term notes. If this happens, the default will be treated as if
it has not occurred. No one can waive a payment default on your note, however,
without the approval of the particular Holder of that note.

Book-entry and other indirect holders should consult their banks or brokers for
information on how to instruct the Holder to give notice or direction to or make
a request of the trustee and how to declare or cancel an acceleration of the
maturity.

WE WILL GIVE THE TRUSTEE INFORMATION ABOUT DEFAULTS ANNUALLY
We will furnish to the trustee every year a written statement of two of our
officers certifying that to their knowledge we are in compliance with the
indenture and the notes, or else specifying any default.

MODIFICATION AND WAIVER OF COVENANTS

There are three types of changes we can make to the indenture and the Series A
medium-term notes.

CHANGES REQUIRING EACH HOLDER'S APPROVAL
First, there are changes that cannot be made without the approval of each Holder
of a note affected by the change. Here is a list of those types of changes:

     - change the stated maturity for any principal or interest payment on a
       note;

     - reduce the principal amount, the amount payable on acceleration of the
       maturity after a default, the interest rate or the redemption price for a
       note;

     - permit redemption of a note if not previously permitted;

     - impair any right a Holder may have to require repayment of his or her
       note;

     - impair any right that a Holder of an indexed note may have to exchange
       the note for securities or other property;

     - change the currency of any payment on a note other than as permitted by
       the note;

     - change the place of payment on a note, if it is in non-global form;

     - impair a Holder's right to sue for payment of any amount due on his or
       her note;

     - reduce the percentage in principal amount of the notes and any other
       affected series of notes, taken together, the approval of whose Holders
       is needed to change the indenture or the notes;

     - reduce the percentage in principal amount of the notes and any other
       affected series of notes, taken separately or together, as the case may
       be, the consent of whose Holders is needed to waive our compliance with
       the indenture or to waive defaults; and

     - change the provisions of the indenture dealing with modification and
       waiver in any other respect, except to increase any required percentage
       referred to above or to add to the provisions that cannot be changed or
       waived without approval.

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

CHANGES NOT REQUIRING APPROVAL
The second type of change does not require any approval by Holders of the Series
A medium-term notes. This type is limited to clarifications and changes that
would not adversely affect the notes in any material respect. We also do not
need any approval to make changes that affect only debt securities to be issued
under the indenture after the changes take effect.

We may also make changes or obtain waivers that do not adversely affect a
particular note, even if they affect other notes or debt securities. In those
cases, we do not need to obtain the approval of the Holder of that note; we need
only obtain any required approvals from the Holders of the affected notes or
other debt securities.

CHANGES REQUIRING MAJORITY APPROVAL
Any other change to the indenture and the Series A medium-term notes would
require the following approval:

     - If the change affects only the Series A medium-term notes, it must be
       approved by the Holders of a majority in principal amount of the Series A
       medium-term notes.

     - If the change affects the Series A medium-term notes as well as one or
       more other series of debt securities issued under the indenture, it must
       be approved by the Holders of a majority in principal amount of the
       Series A medium-term notes and all other series affected by the change,
       with the Series A medium-term notes and all the other series voting
       together as one class for this purpose.

In each case, the required approval must be given by written consent.

The same majority approval would be required for us to obtain a waiver of any of
our covenants in the indenture. If the Holders approve a waiver of a covenant,
we will not have to comply with that covenant. The Holders, however, cannot
approve a waiver of any provision in a particular note, or in the indenture as
it affects that note, that we cannot change without the approval of the Holder
of that note as described above in "-- Changes Requiring Each Holder's
Approval," unless that Holder approves the waiver.

Book-entry and other indirect holders should consult their banks or brokers for
information on how approval may be granted or denied if we seek to change the
indenture or the notes or request a waiver.

SPECIAL RULES FOR ACTION BY HOLDERS

When Holders take any action under the indenture, such as giving a notice of
default, declaring an acceleration, approving any change or waiver or giving the
trustee an instruction, we will apply the following rules. We may apply similar
rules to other series of debt securities issued under the indenture.

ONLY OUTSTANDING NOTES ARE ELIGIBLE
Only Holders of outstanding Series A medium-term notes will be eligible to
participate in any action by Holders of those debt securities. Also, we will
count only outstanding notes in determining whether the various percentage
requirements for taking action have been met. For these purposes, a note will
not be "outstanding":

     - if it has been surrendered for cancellation;

     - if we have deposited or set aside, in trust for its Holder, money for its
       payment or redemption;

--------------------------------------------------------------------------------
                                                                             181
<PAGE>   214
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

     - if we have fully defeased it as described above under "-- Defeasance and
       Covenant Defeasance -- Full Defeasance;" or

     - if we or one of our affiliates, such as UBS Warburg LLC or PaineWebber
       Incorporated, is the beneficial owner.

In some situations, Holders of debt securities of other series may be eligible
to participate in an action by Holders of your series of the notes. In that
event, we may follow special rules in calculating the principal amount of their
debt securities that is to be treated as outstanding for the purposes described
above. This may happen, for example, if the principal amount is payable in a
foreign currency, increases over time or is not to be fixed until maturity. For
any note of the kind described below, we will decide how much principal amount
to attribute to the note as follows:

     - For an original issue discount note, we will use the principal amount
       that would be due and payable on the action date if the maturity of the
       debt security were accelerated to that date because of a default;

     - For a note whose principal amount is not known, we will use any amount
       that we indicate in the prospectus supplement for that note. The
       principal amount of a note may not be known, for example, because it is
       based on an index that changes from time to time and the principal amount
       is not to be determined until a later date; or

     - For notes with a principal amount denominated in one or more foreign
       currencies or currency units, we will use the U.S. dollar equivalent,
       which we will determine.

DETERMINING RECORD DATES FOR ACTION BY HOLDERS
We will generally be entitled to set any day as a record date for the purpose of
determining the Holders that are entitled to take action under the indenture. In
certain limited circumstances, only the trustee will be entitled to set a record
date for action by Holders. If we or the trustee set a record date for an
approval or other action to be taken by Holders, that vote or action may be
taken only by persons or entities who are Holders on the record date and must be
taken during the period that we specify for this purpose, or that the trustee
specifies if it sets the record date. We or the trustee, as applicable, may
shorten or lengthen this period from time to time. This period, however, may not
extend beyond the 180th day after the record date for the action. In addition,
record dates for any global note may be set in accordance with procedures
established by the depositary from time to time. Accordingly, record dates for
global notes may differ from those for other debt securities.

FORM, EXCHANGE AND TRANSFER

If the notes cease to be issued in global form, they will be issued:

     - only in fully registered form;

     - without interest coupons; and

     - unless we indicate otherwise in your prospectus supplement, in
       denominations of $1,000 and that are multiples of $1,000.

Holders may exchange their notes for notes of smaller denominations (subject to
the limit above) or combined into fewer notes of larger denominations, as long
as the total principal amount is not changed.

Holders may exchange or transfer their notes at the office of the trustee. We
have appointed the trustee to act as our agent for registering notes in the
names of Holders and transferring notes. We may appoint another entity to
perform these functions or perform them ourselves.

--------------------------------------------------------------------------------
 182
<PAGE>   215
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

Holders will not be required to pay a service charge to transfer or exchange
their notes, but they may be required to pay for any tax or other governmental
charge associated with the exchange or transfer. The transfer or exchange will
be made only if our transfer agent is satisfied with the Holder's proof of legal
ownership.

If we have designated additional transfer agents for your note, they will be
named in your prospectus supplement. We may appoint additional transfer agents
or cancel the appointment of any particular transfer agent. We may also approve
a change in the office through which any transfer agent acts.

If any notes are redeemable and we redeem less than all those notes, we may
block the transfer or exchange of those notes during the period beginning 15
days before the day we mail the notice of redemption and ending on the day of
that mailing, in order to freeze the list of Holders who will receive the
mailing. We may also refuse to register transfers of or exchange any note
selected for redemption, except that we will continue to permit transfers and
exchanges of the unredeemed portion of any note being partially redeemed.

If a note is issued as a global note, only the depositary will be entitled to
transfer and exchange the note as described in this subsection, since it will be
the sole Holder of the note.

PAYMENT MECHANICS

WHO RECEIVES PAYMENTS?
If interest is due on a note on an interest payment date, we will pay the
interest to the person or entity in whose name the note is registered at the
close of business on the regular record date (see below) relating to the
interest payment date. If interest is due at maturity but on a day that is not
an interest payment date, we will pay the interest to the person or entity
entitled to receive the principal of the note. If principal or another amount
besides interest is due on a note at maturity, we will pay the amount to the
Holder of the note against surrender of the note at a proper place of payment
(or, in the case of a global note, in accordance with the applicable policies of
the depositary).

REGULAR RECORD DATES FOR INTEREST
Unless we specify otherwise in the applicable prospectus supplement, the regular
record date relating to an interest payment date for any fixed rate note will be
the May 1 or November 1 next preceding that interest payment date, and for any
floating rate note will be the 15th calendar day before that interest payment
date, in each case whether or not the record date is a business day. For the
purpose of determining the Holder at the close of business on a regular record
date when business is not being conducted, the close of business will mean 5:00
P.M., New York City time, on that day.

HOW WE WILL MAKE PAYMENTS DUE IN U.S. DOLLARS
We will follow the practices described in this subsection when paying amounts
due in U.S. dollars. Payments of amounts due in other currencies will be made as
described in the next subsection.

PAYMENTS ON GLOBAL NOTES.  We will make payments on a global note in accordance
with the applicable policies of the depositary as in effect from time to time.
Under those policies, we will pay directly to the depositary, or its nominee,
and not to any indirect holders who own beneficial interests in the global note.
An indirect holder's right to receive those payments will be governed by the
rules and practices of the depositary and its participants, as described under
"--What Is a Global Note?".

PAYMENTS ON NON-GLOBAL NOTES.  We will make payments on a note in non-global
form as follows. We will pay interest that is due on an interest payment date by
check mailed on the interest payment date to the Holder at his or her address
shown on the trustee's records as of the close of business on the regular record
date. We will make all other payments by check at the paying agent described

--------------------------------------------------------------------------------
                                                                             183
<PAGE>   216

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

below, against surrender of the note. All payments by check will be made in
next-day funds--that is, in funds that become available on the day after the
check is cashed.

Alternatively, if a non-global note has a face amount of at least $1,000,000 and
the Holder asks us to do so, we will pay any amount that becomes due on the note
by wire transfer of immediately available funds to an account at a bank in New
York City, on the due date. To request wire payment, the Holder must give the
paying agent appropriate wire transfer instructions at least five business days
before the requested wire payment is due. In the case of any interest payment
due on an interest payment date, the instructions must be given by the person or
entity who is the Holder on the relevant regular record date. In the case of any
other payment, payment will be made only after the note is surrendered to the
paying agent. Any wire instructions, once properly given, will remain in effect
unless and until new instructions are given in the manner described above.

Book-entry and other indirect holders should consult their banks or brokers for
information on how they will receive payments on their notes.

HOW WE WILL MAKE PAYMENTS DUE IN OTHER CURRENCIES
We will follow the practices described in this subsection when paying amounts
that are due in a specified currency other than U.S. dollars.

PAYMENTS ON GLOBAL NOTES.  We will make payments on a global note in accordance
with the applicable policies of the depositary as in effect from time to time.
We understand that these policies, as currently in effect at DTC, are as
follows:

Unless otherwise indicated in your prospectus supplement, if you are an indirect
holder of global notes denominated in a specified currency other than U.S.
dollars and if you elect to receive payments in that other currency, you must
notify the participant through which your interest in the global note is held of
your election:

     - on or before the applicable regular record date, in the case of a payment
       of interest, or

     - on or before the 16th day prior to stated maturity, or any redemption or
       repayment date, in the case of payment of principal or any premium.

You may elect to receive all or only a portion of any interest, principal or
premium payment in a specified currency other than U.S. dollars.

Your participant must, in turn, notify DTC of your election on or before the
third DTC business day after that regular record date, in the case of a payment
of interest, and on or before the 12th DTC business day prior to stated
maturity, or on the redemption or repayment date if your note is redeemed or
repaid earlier, in the case of a payment of principal or any premium.

DTC, in turn, will notify the paying agent of your election in accordance with
DTC's procedures.

If complete instructions are received by the participant and forwarded by the
participant to DTC, and by DTC to the paying agent, on or before the dates noted
above, the paying agent, in accordance with DTC's instructions, will make the
payments to you or your participant by wire transfer of immediately available
funds to an account maintained by you or your participant with a bank located in
the country issuing the specified currency or in another jurisdiction acceptable
to us and the paying agent.

If the foregoing steps are not properly completed, we expect DTC to inform the
paying agent that payment is to be made in U.S. dollars. In that case, we or our
agent will convert the payment to U.S. dollars in the manner described below
under "--Conversion to U.S. Dollars." We expect that we or our agent will then
make the payment in U.S. dollars to DTC, and that DTC in turn will pass it along
to its participants.

DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

Book-entry and other indirect holders of a global note denominated in a currency
other than U.S. dollars should consult their banks or brokers for information on
how to request payment in the specified currency.

PAYMENTS ON NON-GLOBAL NOTES.  Except as described in the second to last
paragraph under this heading, we will make payments on notes in non-global form
in the applicable specified currency. We will make these payments by wire
transfer of immediately available funds to any account that is maintained in the
applicable specified currency at a bank designated by the Holder and is
acceptable to us and the trustee. To designate an account for wire payment, the
Holder must give the paying agent appropriate wire instructions at least five
business days before the requested wire payment is due. In the case of any
interest payment due on an interest payment date, the instructions must be given
by the person or entity who is the Holder on the regular record date. In the
case of any other payment, the payment will be made only after the note is
surrendered to the paying agent. Any instructions, once properly given, will
remain in effect unless and until new instructions are properly given in the
manner described above.

If a Holder fails to give instructions as described above, we will notify the
Holder at the address in the trustee's records and will make the payment within
five business days after the Holder provides appropriate instructions. Any late
payment made in these circumstances will be treated under the indenture as if
made on the due date, and no interest will accrue on the late payment from the
due date to the date paid.

Although a payment on a note in non-global form may be due in a specified
currency other than U.S. dollars, we will make the payment in U.S. dollars if
the Holder asks us to do so. To request U.S. dollar payment, the Holder must
provide appropriate written notice to the trustee at least five business days
before the next due date for which payment in U.S. dollars is requested. In the
case of any interest payment due on an interest payment date, the request must
be made by the person or entity who is the Holder on the regular record date.
Any request, once properly made, will remain in effect unless and until revoked
by notice properly given in the manner described above.

Indirect holders of a note with a specified currency other than U.S. dollars
should contact their banks or brokers for information about how to receive
payments in the specified currency or in U.S. dollars.

CONVERSION TO U.S. DOLLARS.  When we are asked by a Holder to make payments in
U.S. dollars of an amount due in another currency, either on a global note or a
non-global note as described above, we will determine the U.S. dollar amount the
Holder receives as follows. The exchange rate agent described below will request
currency bid quotations expressed in U.S. dollars from three or, if three are
not available, then two, recognized foreign exchange dealers in New York City,
any of which may be the exchange rate agent, an affiliate of UBS, as of 11:00
A.M., New York City time, on the second business day before the payment date.
Currency bid quotations will be requested on an aggregate basis, for all Holders
of notes requesting U.S. dollar payments of amounts due on the same date in the
same specified currency. The U.S. dollar amount the Holder receives will be
based on the highest acceptable currency bid quotation received by the exchange
rate agent. If the exchange rate agent determines that at least two acceptable
currency bid quotations are not available on that second business day, the
payment will be made in the specified currency.

To be acceptable, a quotation must be given as of 11:00 A.M., New York City
time, on the second business day before the due date and the quoting dealer must
commit to execute a contract at the quotation in the total amount due in that
currency on all series of notes. If some but not all of the relevant notes are
LIBOR notes or EURIBOR notes, the second preceding business day will be
determined for this purpose as if none of those notes were LIBOR notes or
EURIBOR notes.

--------------------------------------------------------------------------------
                                                                             185
<PAGE>   218
DESCRIPTION OF NOTES WE MAY OFFER
--------------------------------------------------------------------------------

A Holder that requests payment in U.S. dollars will bear all associated currency
exchange costs, which will be deducted from the payment.

WHEN THE SPECIFIED CURRENCY IS NOT AVAILABLE.  If we are obligated to make any
payment in a specified currency other than U.S. dollars, and the specified
currency or any successor currency is not available to us or cannot be paid to
you due to circumstances beyond our control--such as the imposition of exchange
controls or a disruption in the currency markets--we will be entitled to satisfy
our obligation to make the payment in that specified currency by making the
payment in U.S. dollars, on the basis of the most recently available exchange
rate.

For a specified currency other than U.S. dollars, the exchange rate will be the
noon buying rate for cable transfers of the specified currency in New York City
as quoted by the Federal Reserve Bank of New York on the then-most recent day on
which that bank has quoted that rate.

The foregoing will apply to any note, whether in global or non-global form, and
to any payment, including a payment at maturity. Any payment made under the
circumstances and in a manner described above will not result in a default under
any debt security or the indenture.

THE EURO.  The euro may be a specified currency for some notes. On 1 January
1999, the euro became the legal currency for the 11 member states participating
in the European Economic and Monetary Union. During a transition period from 1
January 1999 to 31 December 2001 and for a maximum of six months thereafter, the
former national currencies of these 11 member states will continue to be legal
tender in their country of issue, at rates irrevocably fixed on 31 December
1998.

EXCHANGE RATE AGENT.  If we issue a note in a specified currency other than U.S.
dollars, we will appoint a financial institution to act as the exchange rate
agent and will name the institution initially appointed when the debt security
is originally issued in the applicable prospectus supplement. We may select UBS
Warburg LLC or another of our affiliates to perform this role. We may change the
exchange rate agent from time to time after the original issue date of the note
without your consent and without notifying you of the change.

All determinations made by the exchange rate agent will be at its sole
discretion unless we state in your prospectus supplement that any determination
is subject to our approval. In the absence of manifest error, those
determinations will be conclusive for all purposes and binding on you and us,
without any liability on the part of the exchange rate agent.

PAYMENT WHEN OFFICES ARE CLOSED
If any payment is due on a note on a day that is not a business day, we will
make the payment on the next day that is a business day. Payments postponed to
the next business day in this situation will be treated under the indenture as
if they were made on the original due date. Postponement of this kind will not
result in a default under any note or the indenture, and no interest will accrue
on the postponed amount from the original due date to the next day that is a
business day. The term business day has a special meaning, which we describe
above under "-- Special Rate Calculation Terms."

PAYING AGENT
We may appoint one or more financial institutions to act as our paying agents,
at whose designated offices notes in non-global entry form may be surrendered
for payment at their maturity. We call each of those offices a paying agent. We
may add, replace or terminate paying agents from time to time. We may also
choose to act as our own paying agent. Initially, we have appointed the trustee,
at its corporate trust office in New York City, as the paying agent. We must
notify you of changes in the paying agents.

SETTLEMENT MECHANICS
The settlement mechanics applicable to notes calling for physical settlement
will be described in the applicable prospectus supplement.

UNCLAIMED PAYMENTS
Regardless of who acts as paying agent, all money paid by us to a paying agent
that remains unclaimed at the end of two years after the amount is due to a
Holder will be repaid to us. After that two-year period, the Holder may look
only to us for payment and not to the trustee, any other paying agent or anyone
else.

NOTICES

Notices to be given to Holders of a global note will be given only to the
depositary, in accordance with its applicable policies as in effect from time to
time. Notices to be given to Holders of notes not in global form will be sent by
mail to the respective addresses of the Holders as they appear in the trustee's
records, and will be deemed given when mailed. Neither the failure to give any
notice to a particular Holder, nor any defect in a notice given to a particular
Holder, will affect the sufficiency of any notice given to another Holder.

Book-entry and other indirect holders should consult their banks or brokers for
information on how they will receive notices.

OUR RELATIONSHIP WITH THE TRUSTEE

U.S. Bank Trust National Association is initially serving as the trustee for the
notes and all other series of debt securities to be issued under the indenture.
U.S. Bank Trust National Association has provided commercial banking and other
services for us and our affiliates in the past and may do so in the future.
Among other things, U.S. Bank Trust National Association provides us with a line
of credit, holds debt securities issued by us and serves as trustee or agent
with regard to other debt obligations of UBS or its subsidiaries.

Considerations Relating to Indexed Notes

We use the term "indexed notes" to mean notes whose value is linked to an
underlying property or index, including equity and credit indexed notes and
credit linked notes. Indexed notes may present a high level of risk, and those
who invest in some indexed notes may lose their entire investment. In addition,
the treatment of indexed notes for U.S. federal income tax purposes is often
unclear due to the absence of any authority specifically addressing the issues
presented by any particular indexed note. Thus, if you propose to invest in
indexed notes, you should independently evaluate the federal income tax
consequences of purchasing an indexed note that apply in your particular
circumstances. You should also read "U.S. Tax Considerations" for a discussion
of U.S. tax matters.

INVESTORS IN INDEXED SECURITIES COULD LOSE THEIR INVESTMENT

The amount of principal and/or interest payable on an indexed note and the cash
value or physical settlement value of a physically settled note will be
determined by reference to the price, value or level of one or more securities,
currencies, commodities or other properties, any other financial, economic or
other measure or instrument, including the occurrence or non-occurrence of any
event or circumstance, and/or one or more indices or baskets of any of these
items. We refer to each of these as an "index". The direction and magnitude of
the change in the price, value or level of the relevant index will determine the
amount of principal and/or interest payable on an indexed note and the cash
value or physical settlement value of a physically settled note. The terms of a
particular indexed note may or may not include a guaranteed return of a
percentage of the face amount at maturity or a minimum interest rate. Thus, if
you purchase an indexed note, you may lose all or a portion of the principal or
other amount you invest and may receive no interest on your investment.

THE ISSUER OF A SECURITY OR CURRENCY THAT SERVES AS AN INDEX COULD TAKE ACTIONS
THAT MAY ADVERSELY AFFECT AN INDEXED NOTES

The issuer of a note that serves as an index or part of an index for an indexed
note will have no involvement in the offer and sale of the indexed note and no
obligations to the Holder of the indexed note. The issuer may take actions, such
as a merger or sale of assets, without regard to the interests of the Holder.
Any of these actions could adversely affect the value of a note indexed to that
security or to an index of which that security is a component.

If the index for an indexed note includes a non-U.S. dollar currency or other
asset denominated in a non-U.S. dollar currency, the government that issues that
currency will also have no involvement in the offer and sale of the indexed note
and no obligations to the Holder of the indexed note. That government may take
actions that could adversely affect the value of the security. See
"Considerations Relating to Notes Denominated or Payable in or Linked to a
Non-U.S. Dollar Currency--Government Policy Can Adversely Affect Currency
Exchange Rates and an Investment in a Non-U.S. Dollar Note" below for more
information about these kinds of government actions.

AN INDEXED NOTE MAY BE LINKED TO A VOLATILE INDEX, WHICH COULD HURT YOUR
INVESTMENT

Some indices are highly volatile, which means that their value may change
significantly, up or down, over a short period of time. The amount of principal
or interest that can be expected to become payable on an indexed note may vary
substantially from time to time. Because the amounts payable with respect to an
indexed note are generally calculated based on the value or level of the
relevant index on a specified date or over a limited period of time, volatility
in the index increases the risk that

--------------------------------------------------------------------------------
 188
<PAGE>   221
CONSIDERATIONS RELATING TO INDEXED NOTES
--------------------------------------------------------------------------------

the return on the indexed note may be adversely affected by a fluctuation in the
level of the relevant index.

The volatility of an index may be affected by political or economic events,
including governmental actions, or by the activities of participants in the
relevant markets. Any of these events or activities could adversely affect the
value of an indexed note.

AN INDEX TO WHICH A NOTE IS LINKED COULD BE CHANGED OR BECOME UNAVAILABLE

Some indices compiled by us or our affiliates or third parties may consist of or
refer to several or many different securities, commodities or currencies or
other instruments or measures. The compiler of such an index typically reserves
the right to alter the composition of the index and the manner in which the
value or level of the index is calculated. An alteration may result in a
decrease in the value of or return on an indexed note that is linked to the
index. The indices for our indexed notes may include published indices of this
kind or customized indices developed by us or our affiliates in connection with
particular issues of indexed notes.

A published index may become unavailable, or a customized index may become
impossible to calculate in the normal manner, due to events such as war, natural
disasters, cessation of publication of the index or a suspension or disruption
of trading in one or more securities, commodities or currencies or other
instruments or measures on which the index is based. If an index becomes
unavailable or impossible to calculate in the normal manner, the terms of a
particular indexed note may allow us to delay determining the amount payable as
principal or interest on an indexed debt note, or we may use an alternative
method to determine the value of the unavailable index. Alternative methods of
valuation are generally intended to produce a value similar to the value
resulting from reference to the relevant index. However, it is unlikely that any
alternative method of valuation we use will produce a value identical to the
value that the actual index would produce. If we use an alternative method of
valuation for a note linked to an index of this kind, the value of the note, or
the rate of return on it, may be lower than it otherwise would be.

Some indexed notes are linked to indices that are not commonly used or that have
been developed only recently. The lack of a trading history may make it
difficult to anticipate the volatility or other risks associated with an indexed
note of this kind. In addition, trading in these indices or their underlying
stocks, commodities or currencies or other instruments or measures, or options
or futures contracts on these stocks, commodities or currencies or other
instruments or measures, may be limited, which could increase their volatility
and decrease the value of the related indexed notes or the rates of return on
them.

WE MAY ENGAGE IN HEDGING ACTIVITIES THAT COULD ADVERSELY AFFECT AN INDEXED NOTE

In order to hedge an exposure on a particular indexed note, we may, directly or
through our affiliates, enter into transactions involving the securities,
commodities or currencies or other instruments or measures that underlie the
index for that note, or involving derivative instruments, such as swaps, options
or futures, on the index or any of its component items. By engaging in
transactions of this kind, we could adversely affect the value of an indexed
note. It is possible that we could achieve substantial returns from our hedging
transactions while the value of the indexed note may decline.

INFORMATION ABOUT INDICES MAY NOT BE INDICATIVE OF FUTURE PERFORMANCE

If we issue an indexed note, we may include historical information about the
relevant index in the applicable prospectus supplement. Any information about
indices that we may provide will be furnished as a matter of information only,
and you should not regard the information as indicative of the range of, or
trends in, fluctuations in the relevant index that may occur in the future.

WE MAY HAVE CONFLICTS OF INTEREST REGARDING AN INDEXED NOTE

UBS Warburg LLC, PaineWebber Incorporated and our other affiliates may have
conflicts of interest with respect to some indexed notes. UBS Warburg LLC,
PaineWebber Incorporated and our other affiliates may engage in trading,
including trading for hedging purposes, for their proprietary accounts or for
other accounts under their management, in indexed notes and in the securities,
commodities or currencies or other instruments or measures on which the index is
based or in other derivative instruments related to the index or its component
items. These trading activities could adversely affect the value of indexed
notes. We and our affiliates may also issue or underwrite securities or
derivative instruments that are linked to the same index as one or more indexed
securities. By introducing competing products into the marketplace in this
manner, we could adversely affect the value of an indexed note.

UBS Warburg LLC, PaineWebber Incorporated or another of our affiliates may serve
as calculation agent for the indexed notes and may have considerable discretion
in calculating the amounts payable in respect of the notes. To the extent that
UBS Warburg LLC, PaineWebber Incorporated or another of our affiliates
calculates or compiles a particular index, it may also have considerable
discretion in performing the calculation or compilation of the index. Exercising
discretion in this manner could adversely affect the value of an indexed note
based on the index or the rate of return on the note.

Considerations Relating to Notes Denominated or Payable In or Linked to a
Non-U.S. Dollar Currency

If you intend to invest in a non-U.S. dollar note--e.g., a note whose principal
and/or interest is payable in a currency other than U.S. dollars or that may be
settled by delivery of or reference to a non-U.S. dollar currency or property
denominated in or otherwise linked to a non-U.S. dollar currency--you should
consult your own financial and legal advisors as to the currency risks entailed
by your investment. Notes of this kind may not be an appropriate investment for
investors who are unsophisticated with respect to non-U.S. dollar currency
transactions.

The information in this prospectus is directed primarily to investors who are
U.S. residents. Investors who are not U.S. residents should consult their own
financial and legal advisors about currency-related risks particular to their
investment.

AN INVESTMENT IN A NON-U.S. DOLLAR NOTE INVOLVES CURRENCY-RELATED RISKS

An investment in a non-U.S. dollar note entails significant risks that are not
associated with a similar investment in a note that is payable solely in U.S.
dollars and where settlement value is not otherwise based on a non-U.S. dollar
currency. These risks include the possibility of significant changes in rates of
exchange between the U.S. dollar and the various non-U.S. dollar currencies or
composite currencies and the possibility of the imposition or modification of
foreign exchange controls or other conditions by either the United States or
non-U.S. governments. These risks generally depend on factors over which we have
no control, such as economic and political events and the supply of and demand
for the relevant currencies in the global markets.

CHANGES IN CURRENCY EXCHANGE RATES CAN BE VOLATILE AND UNPREDICTABLE

Rates of exchange between the U.S. dollar and many other currencies have been
highly volatile, and this volatility may continue and perhaps spread to other
currencies in the future. Fluctuations in currency exchange rates could
adversely affect an investment in a note denominated in, or where value is
otherwise linked to, a specified currency other than U.S. dollars. Depreciation
of the specified currency against the U.S. dollar could result in a decrease in
the U.S. dollar-equivalent value of payments on the note, including the
principal payable at maturity or settlement value payable upon exercise. That in
turn could cause the market value of the note to fall. Depreciation of the
specified currency against the U.S. dollar could result in a loss to the
investor on a U.S. dollar basis.

GOVERNMENT POLICY CAN ADVERSELY AFFECT CURRENCY EXCHANGE RATES AND AN INVESTMENT
IN A NON-U.S. DOLLAR NOTE

Currency exchange rates can either float or be fixed by sovereign governments.
From time to time, governments use a variety of techniques, such as intervention
by a country's central bank or imposition of regulatory controls or taxes, to
affect the exchange rate of their currencies. Governments may also issue a new
currency to replace an existing currency or alter the exchange rate or exchange
characteristics by devaluation or revaluation of a currency. Thus, a special
risk in purchasing non-U.S. dollar notes is that their yields or payouts could
be significantly and unpredictably affected by governmental actions. Even in the
absence of governmental action directly affecting currency exchange rates,
political or economic developments in the country issuing the specified currency
for a non-U.S. dollar note or elsewhere could lead to significant and sudden
changes in the exchange rate between the U.S. dollar and the specified currency.
These changes could affect the value of the note as participants in the global
currency markets move to buy or sell the specified currency or U.S. dollars in
reaction to these developments.

                                                                             191
<PAGE>   224
CONSIDERATIONS RELATING TO NOTES DENOMINATED OR PAYABLE IN OR LINKED TO A
NON-U.S. DOLLAR CURRENCY
--------------------------------------------------------------------------------

Governments have imposed from time to time and may in the future impose exchange
controls or other conditions, including taxes, with respect to the exchange or
transfer of a specified currency that could affect exchange rates as well as the
availability of a specified currency for a note at its maturity or on any other
payment date. In addition, the ability of a Holder to move currency freely out
of the country in which payment in the currency is received or to convert the
currency at a freely determined market rate could be limited by governmental
actions.

NON-U.S. DOLLAR NOTES MAY PERMIT US TO MAKE PAYMENTS IN U.S. DOLLARS OR DELAY
PAYMENT IF WE ARE UNABLE TO OBTAIN THE SPECIFIED CURRENCY

Notes payable in a currency other than U.S. dollars may provide that, if the
other currency is subject to convertibility, transferability, market disruption
or other conditions affecting its availability at or about the time when a
payment on the notes comes due because of circumstances beyond our control, we
will be entitled to make the payment in U.S. dollars or delay making the
payment. These circumstances could include the imposition of exchange controls
or our inability to obtain the other currency because of a disruption in the
currency markets. If we made payment in U.S. dollars, the exchange rate we would
use would be determined in the manner described above under "Description of
Notes We May Offer--Payment Mechanics--How We Will Make Payments Due in Other
Currencies--When the Specified Currency Is Not Available". A determination of
this kind may be based on limited information and would involve significant
discretion on the part of our foreign exchange agent. As a result, the value of
the payment in U.S. dollars an investor would receive on the payment date may be
less than the value of the payment the investor would have received in the other
currency if it had been available, or may be zero. In addition, a government may
impose extraordinary taxes on transfers of a currency. If that happens, we will
be entitled to deduct these taxes from any payment on notes payable in that
currency.

WE WILL NOT ADJUST NON-U.S. DOLLAR NOTES TO COMPENSATE FOR CHANGES IN CURRENCY
EXCHANGE RATES

Except as described above, we will not make any adjustment or change in the
terms of a non-U.S. dollar note in the event of any change in exchange rates for
the relevant currency, whether in the event of any devaluation, revaluation or
imposition of exchange or other regulatory controls or taxes or in the event of
other developments affecting that currency, the U.S. dollar or any other
currency. Consequently, investors in non-U.S. dollar notes will bear the risk
that their investment may be adversely affected by these types of events.

IN A LAWSUIT FOR PAYMENT ON A NON-U.S. DOLLAR NOTE, AN INVESTOR MAY BEAR
CURRENCY EXCHANGE RISK

Our notes will be governed by New York law. Under Section 27 of the New York
Judiciary Law, a state court in the State of New York rendering a judgment on a
note denominated in a currency other than U.S. dollars would be required to
render the judgment in the specified currency; however, the judgment would be
converted into U.S. dollars at the exchange rate prevailing on the date of entry
of the judgment. Consequently, in a lawsuit for payment on a note denominated in
a currency other than U.S. dollars, investors would bear currency exchange risk
until judgment is entered, which could be a long time.

In courts outside of New York, investors may not be able to obtain judgment in a
specified currency other than U.S. dollars. For example, a judgment for money in
an action based on a non-U.S. dollar note in many other U.S. federal or state
courts ordinarily would be enforced in the United States only in U.S. dollars.
The date used to determine the rate of conversion of the currency in which any

--------------------------------------------------------------------------------
 192

CONSIDERATIONS RELATING TO NOTES DENOMINATED OR PAYABLE IN OR LINKED TO A
NON-U.S. DOLLAR CURRENCY
--------------------------------------------------------------------------------

particular note is denominated into U.S. dollars will depend upon various
factors, including which court renders the judgment.

INFORMATION ABOUT EXCHANGE RATES MAY NOT BE INDICATIVE OF FUTURE PERFORMANCE

If we issue a non-U.S. dollar note, we may include in the applicable prospectus
supplement a currency supplement that provides information about historical
exchange rates for the relevant non-U.S. dollar currency or currencies. Any
information about exchange rates that we may provide will be furnished as a
matter of information only, and you should not regard the information as
indicative of the range of, or trends in, fluctuations in currency exchange
rates that may occur in the future. That rate will likely differ from the
exchange rate used under the terms that apply to a particular note.

U.S. Tax Considerations

This section describes the material United States federal income tax
consequences to United States Holders, as defined below, of owning the Series A
medium-term notes and is the opinion of Sullivan & Cromwell, United States tax
counsel to UBS. It applies to you only if you hold your notes as capital assets
for tax purposes. This section does not apply to you if you are a member of a
class of holders subject to special rules, such as:

-  a dealer in securities or currencies;

-  a trader in securities that elects to use a mark-to-market method of
   accounting for your securities holdings;

-  a bank;

-  a life insurance company;

-  a tax-exempt organization;

-  a person who holds notes that are a hedge or that are hedged against interest
   rate or currency risks;

-  a person who holds notes as part of a straddle or conversion transaction for
   tax purposes; or

-  a person whose functional currency for tax purposes is not the U.S. dollar

-  except as otherwise noted under "Backup Withholding and Information
   Reporting", a person that is not a United States holder, as defined below.

This section deals only with notes that are due to mature 30 years or less from
the date on which they are issued. The United States federal income tax
consequences of owning notes that are due to mature more than 30 years from
their date of issue will be discussed in an applicable prospectus supplement.
This section is based on the Internal Revenue Code of 1986, as amended, its
legislative history, existing and proposed regulations under the Internal
Revenue Code, and published rulings and court decisions, all as currently in
effect. These laws are subject to change, possibly on a retroactive basis.

-  Please consult your own tax advisor concerning the consequences of owning
   these notes in your particular circumstances under the Internal Revenue Code
   and the laws of any other taxing jurisdiction.

You are a United States holder if you are a beneficial owner of a note and you
are:

-  a citizen or resident of the United States;

-  a domestic corporation;

-  an estate whose income is subject to United States federal income tax
   regardless of its source; or

-  a trust if a United States court can exercise primary supervision over the
   trust's administration and one or more United States persons are authorized
   to control all substantial decisions of the trust.

PAYMENTS OF INTEREST

Except as described below in the case of interest on a discount note that is not
qualified stated interest, each as defined below under "Original Issue
Discount--General", you will be taxed on any interest on your note, whether
payable in U.S. dollars or a foreign currency, including a composite currency or
basket of currencies other than U.S. dollars, as ordinary income at the time you
receive the interest or it accrues, depending on your method of accounting for
tax purposes. Interest we pay on the notes and

--------------------------------------------------------------------------------
 194
<PAGE>   227
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

original issue discount, if any, accrued with respect to the notes (as described
below under "Original Issue Discount") constitutes income from sources outside
the United States, but, with certain exceptions, will be "passive" or "financial
service income," which is treated separately from other types of income for
purposes of computing the foreign tax credit limitation.

CASH BASIS TAXPAYERS.  If you are a taxpayer that uses the cash receipts and
disbursements method of accounting for tax purposes and you receive an interest
payment that is denominated in, or determined by reference to, a foreign
currency, you must recognize income equal to the U.S. dollar value of the
interest payment, based on the exchange rate in effect on the date of receipt,
regardless of whether you actually convert the payment into U.S. dollars.

ACCRUAL BASIS TAXPAYERS.  If you are a taxpayer who uses an accrual method of
accounting for tax purposes, you may determine the amount of income that you
recognize with respect to an interest payment denominated in, or determined by
reference to, a foreign currency by using one of two methods. Under the first
method, you will determine the amount of income accrued based on the average
exchange rate in effect during the interest accrual period or, with respect to
an accrual period that spans two taxable years, that part of the period within
the taxable year.

If you elect the second method, you would determine the amount of income accrued
on the basis of the exchange rate in effect on the last day of the accrual
period or, in the case of an accrual period that spans two taxable years, the
exchange rate in effect on the last day of the part of the period within the
taxable year. Additionally, under this second method, if you receive a payment
of interest within five business days of the last day of your accrual period or
taxable year, you may instead translate the interest accrued into U.S. dollars
at the exchange rate in effect on the day that you actually receive the interest
payment. If you elect the second method, it will apply to all debt instruments
that you hold at the beginning of the first taxable year to which the election
applies and to all debt instruments that you subsequently acquire. You may not
revoke this election without the consent of the Internal Revenue Service.

When you actually receive an interest payment, including a payment attributable
to accrued but unpaid interest upon the sale or retirement of your note,
denominated in, or determined by reference to, a foreign currency for which you
accrued an amount of income, you will recognize ordinary income or loss measured
by the difference, if any, between the exchange rate that you used to accrue
interest income and the exchange rate in effect on the date of receipt,
regardless of whether you actually convert the payment into U.S. dollars.
However, you may not treat this ordinary income gain or loss as an adjustment to
the interest income you receive.

ORIGINAL ISSUE DISCOUNT

GENERAL.  If you own a note, other than a short-term note with a term of one
year or less, it will be treated as a discount note issued at an original issue
discount if the amount by which the note's stated redemption price at maturity
exceeds its issue price is more than a de minimis amount. Generally, a note's
issue price will be the first price at which a substantial amount of notes
included in the issue of which the note is a part is sold to persons other than
bond houses, brokers, or similar persons or organizations acting in the capacity
of underwriters, placement agents, or wholesalers. A note's stated redemption
price at maturity is the total of all payments provided by the note that are not
payments of qualified stated interest. Generally, an interest payment on a note
is qualified stated interest if it is one of a series of stated interest
payments on a note that are unconditionally payable at least annually at a
single fixed rate, with certain exceptions for lower rates paid during some
periods, applied to the outstanding principal amount of the note. There are
special rules for variable rate notes that are discussed under "--Variable Rate
Notes".

--------------------------------------------------------------------------------
                                                                             195
<PAGE>   228
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

In general, your note is not a discount note if the amount by which its stated
redemption price at maturity exceeds its issue price is less than the de minimis
amount of 1/4 of 1% of its stated redemption price at maturity multiplied by the
number of complete years to its maturity. Your note will have de minimis
original issue discount if the amount of the excess is less than the de minimis
amount. If your note has de minimis original issue discount, you must include
the de minimis amount in income as stated principal payments are made on the
note, unless you make the election described below under "--Election to Treat
All Interest as Original Issue Discount". You can determine the includible
amount with respect to each such payment by multiplying the total amount of your
note's de minimis original issue discount by a fraction equal to:

-  the amount of the principal payment made

divided by

-  the stated principal amount of the note.

Generally, if your discount note matures more than one year from its date of
issue, you must include original issue discount in income before you receive
cash attributable to that income. The amount of OID that you must include in
income is calculated using a constant-yield method, and generally you will
include increasingly greater amounts of OID in income over the life of your
note. More specifically, you can calculate the amount of accrued OID that you
must include in income by adding the daily portions of OID with respect to your
discount note for each day during the taxable year or portion of the taxable
year that you hold your discount note. You can determine the daily portion by
allocating to each day in any accrual period a pro rata portion of the OID
allocable to that accrual period. You may select an accrual period of any length
with respect to your note and you may vary the length of each accrual period
over the term of your note. However, no accrual period may be longer than one
year and each scheduled payment of interest or principal on the note must occur
on either the first or final day of an accrual period.

You can determine the amount of OID allocable to an accrual period by:

-  multiplying your discount note's adjusted issue price at the beginning of the
   accrual period by your note's yield to maturity; and then

-  subtracting from this figure the sum of the payments of qualified stated
   interest on your note allocable to the accrual period.

You must determine the note's yield to maturity on the basis of compounding at
the close of each accrual period and adjusting for the length of each accrual
period. Further, you can determine your discount note's adjusted issue price at
the beginning of any accrual period by:

-  adding your note's issue price and any accrued OID for each prior accrual
   period; and then

-  subtracting any payments previously made on your note that were not qualified
   stated interest payments.

If an interval between payments of qualified stated interest on your note
contains more than one accrual period, then, when you determine the amount of
OID allocable to an accrual period, you must allocate the amount of qualified
stated interest payable at the end of the interval, including any qualified
stated interest that is payable on the first day of the accrual period
immediately following the interval, pro rata to each accrual period in the
interval based on their relative lengths. In addition, you must increase the
adjusted issue price at the beginning of each accrual period in the interval by
the amount of any qualified stated interest that has accrued prior to the first
day of the accrual period but that is not payable until the end of the interval.
You may compute the amount of OID allocable to an

--------------------------------------------------------------------------------
 196
<PAGE>   229
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

initial short accrual period by using any reasonable method if all other accrual
periods, other than a final short accrual period, are of equal length.

The amount of OID allocable to the final accrual period is equal to the
difference between:

-  the amount payable at the maturity of your note, other than any payment of
   qualified stated interest; and

-  your note's adjusted issue price as of the beginning of the final accrual
   period.

ACQUISITION PREMIUM.  If you purchase your note for an amount that is less than
or equal to the sum of all amounts, other than qualified stated interest,
payable on your note after the purchase date but is greater than the amount of
your note's adjusted issue price, as determined above under "General", the
excess is acquisition premium. If you do not make the election described below
under "Election to Treat All Interest as Original Issue Discount", then you must
reduce the daily portions of OID by an amount equal to:

-  the excess of your adjusted basis in the note immediately after purchase over

-  the adjusted issue price of the note

divided by

-  the excess of the sum of all amounts payable (other than qualified stated
   interest) on the note after the purchase date

over

-  the note's adjusted issue price.

MARKET DISCOUNT.  You will be treated as if you purchased your note, other than
a short-term note, at a market discount, and your note will be a market discount
note if:

-  in the case of an initial purchaser, you purchase your note for less than its
   issue price as determined above under "General"; and

-  in the case of all purchasers, the note's stated redemption price at maturity
   or, in the case of a discount note, the note's revised issue price, exceeds
   the price you paid for your note by at least 1/4 of 1% of your note's stated
   redemption price at maturity or revised issue price, respectively, multiplied
   by the number of complete years to the note's maturity. To determine the
   revised issue price of your note for these purposes, you generally add any
   OID that has accrued on your note to its issue price.

If your note's stated redemption price at maturity or, in the case of a discount
note, its revised issue price, does not exceed the price you paid for the note
by 1/4 of 1% multiplied by the number of complete years to the note's maturity,
the excess constitutes de minimis market discount, and the rules discussed below
are not applicable to you.

You must treat any gain you recognize on the maturity or disposition of your
market discount note as ordinary income to the extent of the accrued market
discount on your note. Alternatively, you may elect to include market discount
in income currently over the life of your note. If you make this election, it
will apply to all debt instruments with market discount that you acquire on or
after the first day of the first taxable year to which the election applies. You
may not revoke this election without the consent of the Internal Revenue
Service. If you own a market discount note and do not make this election, you
will generally be required to defer deductions for interest on borrowings
allocable to your note in an amount not exceeding the accrued market discount on
your note until the maturity or disposition of your note.

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

<PAGE>   230
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

You will accrue market discount on your market discount note on a straight-line
basis unless you elect to accrue market discount using a constant-yield method.
If you make this election, it will apply only to the note with respect to which
it is made and you may not revoke it.

If you are an accrual-basis taxpayer, you should be aware that legislation has
been proposed that would require you to include market discount in income
currently over the life of your note, subject to certain limitations. We cannot
say whether any such proposal will be enacted or what its effective dates might
be.

PRE-ISSUANCE ACCRUED INTEREST.  An election may be made to decrease the issue
price of your note by the amount of pre-issuance accrued interest if:

-  a portion of the initial purchase price of your note is attributable to
   pre-issuance accrued interest;

-  the first stated interest payment on your note is to be made within one year
   of your note's issue date; and

-  the payment will equal or exceed the amount of pre-issuance accrued interest.

If this election is made, a portion of the first stated interest payment will be
treated as a return of the excluded pre-issuance accrued interest and not as an
amount payable on your note.

NOTES SUBJECT TO CONTINGENCIES INCLUDING OPTIONAL REDEMPTION.  Your note is
subject to a contingency if it provides for an alternative payment schedule or
schedules applicable upon the occurrence of a contingency or contingencies,
other than a remote or incidental contingency, whether such contingency relates
to payments of interest or of principal. In such a case, you must determine the
yield and maturity of your note by assuming that the payments will be made
according to the payment schedule most likely to occur if:

-  the timing and amounts of the payments that comprise each payment schedule
   are known as of the issue date; and

-  one of such schedules is significantly more likely than not to occur.

If there is no single payment schedule that is significantly more likely than
not to occur, other than because of a mandatory sinking fund, you must include
income on your note in accordance with the general rules that govern contingent
payment obligations. These rules will be discussed in the applicable prospectus
supplement.

Notwithstanding the general rules for determining yield and maturity, if your
note is subject to contingencies, and either you or we have an unconditional
option or options that, if exercised, would require payments to be made on the
note under an alternative payment schedule or schedules, then in the case of an
option or options of ours, we will be deemed to exercise or not exercise an
option or combination of options in the manner that minimizes the yield on your
note and, in the case of an option or options that you hold, you will be deemed
to exercise or not exercise an option or combination of options in the manner
that maximizes the yield on your note. If both you and we hold options described
in the preceding sentence, those rules will apply to each option in the order in
which they may be exercised. You may determine the yield on your note for the
purposes of those calculations by using any date on which your note may be
redeemed or repurchased as the maturity date and the amount payable on the date
that you chose in accordance with the terms of your note as the principal amount
payable at maturity.

If a contingency, including the exercise of an option, actually occurs or does
not occur contrary to an assumption made according to the above rules then,
except to the extent that a portion of your note is repaid as a result of this
change in circumstances and solely to determine the amount and accrual of OID,
you must redetermine the yield and maturity of your note by treating your note
as having been

--------------------------------------------------------------------------------
 198

U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

retired and reissued on the date of the change in circumstances for an amount
equal to your note's adjusted issue price on that date.

ELECTION TO TREAT ALL INTEREST AS ORIGINAL ISSUE DISCOUNT.  You may elect to
include in gross income all interest that accrues on your note using the
constant-yield method described above under "General", with the modifications
described below. For purposes of this election, interest will include stated
interest, OID, de minimis original issue discount, market discount, de minimis
market discount and unstated interest, as adjusted by any amortizable bond
premium, described below under "Notes Purchased at a Premium", or acquisition
premium.

If you make this election for your note, then, when you apply the constant-yield
method:

-  the issue price of your note will equal your cost;

-  the issue date of your note will be the date you acquired it; and

-  no payments on your note will be treated as payments of qualified stated
   interest.

Generally, this election will apply only to the note for which you make it;
however, if the note for which this election is made has amortizable bond
premium, you will be deemed to have made an election to apply amortizable bond
premium against interest for all debt instruments with amortizable bond premium,
other than debt instruments the interest on which is excludible from gross
income, that you hold as of the beginning of the taxable year to which the
election applies or any taxable year thereafter. Additionally, if you make this
election for a market discount note, you will be treated as having made the
election discussed above under "Market Discount" to include market discount in
income currently over the life of all debt instruments that you currently hold
or later acquire. You may not revoke any election to apply the constant-yield
method to all interest on a note or the deemed elections with respect to
amortizable bond premium or market discount notes without the consent of the
Internal Revenue Service.

VARIABLE RATE NOTES.  Your note will be a variable rate note if:

-  your note's issue price does not exceed the total noncontingent principal
   payments by more than the lesser of:

     1.  .015 multiplied by the product of the total noncontingent principal
         payments and the number of complete years to maturity from the issue
         date, or

     2.  15 percent of the total noncontingent principal payments; and

-  your note provides for stated interest, compounded or paid at least annually,
   only at:

     1.  one or more qualified floating rates,

     2.  a single fixed rate and one or more qualified floating rates,

     3.  a single objective rate, or

     4.  a single fixed rate and a single objective rate that is a qualified
         inverse floating rate.

Your note will have a variable rate that is a qualified floating rate if:

-  variations in the value of the rate can reasonably be expected to measure
   contemporaneous variations in the cost of newly borrowed funds in the
   currency in which your note is denominated; or

-  the rate is equal to such a rate multiplied by either:

     5.  a fixed multiple that is greater than 0.65 but not more than 1.35, or

--------------------------------------------------------------------------------
                                                                             199
<PAGE>   232
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

     6.  a fixed multiple that is greater than 0.65 but not more than 1.35,
         increased or decreased by a fixed rate; and

-  the value of the rate on any date during the term of your note is set no
   earlier than three months prior to the first day on which that value is in
   effect and no later than one year following that first day.

If your note provides for two or more qualified floating rates that are within
0.25 percentage points of each other on the issue date or can reasonably be
expected to have approximately the same values throughout the term of the note,
the qualified floating rates together constitute a single qualified floating
rate.

Your note will not have a qualified floating rate, however, if the rate is
subject to certain restrictions (including caps, floors, governors, or other
similar restrictions) unless such restrictions are fixed throughout the term of
the note or are not reasonably expected to significantly affect the yield on the
note.

Your note will have a variable rate that is a single objective rate if:

-  the rate is not a qualified floating rate;

-  the rate is determined using a single, fixed formula that is based on
   objective financial or economic information that is not within the control of
   or unique to the circumstances of the issuer or a related party; and

-  the value of the rate on any date during the term of your note is set no
   earlier than three months prior to the first day on which that value is in
   effect and no later than one year following that first day.

Your note will not have a variable rate that is an objective rate, however, if
it is reasonably expected that the average value of the rate during the first
half of your note's term will be either significantly less than or significantly
greater than the average value of the rate during the final half of your note's
term.

An objective rate as described above is a qualified inverse floating rate if:

-  the rate is equal to a fixed rate minus a qualified floating rate; and

-  the variations in the rate can reasonably be expected to inversely reflect
   contemporaneous variations in the cost of newly borrowed funds.

Your note will also have a single qualified floating rate or an objective rate
if interest on your note is stated at a fixed rate for an initial period of one
year or less followed by either a qualified floating rate or an objective rate
for a subsequent period, and either:

-  the fixed rate and the qualified floating rate or objective rate have values
   on the issue date of the note that do not differ by more than 0.25 percentage
   points; or

-  the value of the qualified floating rate or objective rate is intended to
   approximate the fixed rate.

Commercial paper rate notes, prime rate notes, LIBOR notes, EURIBOR notes,
treasury rate notes, CMT rate notes, CD rate notes, federal funds rate notes,
J.J. Kenny rate, and 11th district rate notes generally will be treated as
variable rate notes under these rules.

In general, if your variable rate note provides for stated interest at a single
qualified floating rate or objective rate (or one of those rates after a single
fixed rate for an initial period), all stated interest on your note is qualified
stated interest. In this case, the amount of OID, if any, is determined by
using, for a qualified floating rate or qualified inverse floating rate, the
value as of the issue date of the

--------------------------------------------------------------------------------
 200
<PAGE>   233
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

qualified floating rate or qualified inverse floating rate, or, for any other
objective rate, a fixed rate that reflects the yield reasonably expected for
your note.

If your variable rate note does not provide for stated interest at a single
qualified floating rate or a single objective rate, and also does not provide
for interest payable at a fixed rate other than a single fixed rate for an
initial period, you generally must determine the interest and OID accruals on
your note by:

-  determining a fixed rate substitute for each variable rate provided under
   your variable rate note;

-  constructing the equivalent fixed rate debt instrument (using the fixed rate
   substitute described above);

- determining the amount of qualified stated interest and OID with respect to
  the equivalent fixed rate debt instrument; and

- adjusting for actual variable rates during the applicable accrual period.

When you determine the fixed rate substitute for each variable rate provided
under the variable rate note, you generally will use the value of each variable
rate as of the issue date or, for an objective rate that is not a qualified
inverse floating rate, a rate that reflects the reasonably expected yield on
your note.

If your variable rate note provides for stated interest either at one or more
qualified floating rates or at a qualified inverse floating rate, and also
provides for stated interest at a single fixed rate other than a single fixed
rate for an initial period, you generally must determine interest and OID
accruals by using the method described in the previous paragraph. However, your
variable rate note will be treated, for purposes of the first three steps of the
determination, as if your note had provided for a qualified floating rate, or a
qualified inverse floating rate, rather than the fixed rate. The qualified
floating rate, or qualified inverse floating rate, that replaces the fixed rate
must be such that the fair market value of your variable rate note as of the
issue date approximates the fair market value of an otherwise identical debt
instrument that provides for the qualified floating rate, or qualified inverse
floating rate, rather than the fixed rate.

SHORT-TERM NOTES.  In general, if you are an individual or other cash basis
United States holder of a short-term note, you are not required to accrue OID,
as specially defined below for the purposes of this paragraph, for United States
federal income tax purposes unless you elect to do so. However, you may be
required to include any stated interest in income as you receive it. If you are
an accrual basis taxpayer, a taxpayer in a special class, including, but not
limited to, a regulated investment company, common trust fund, or a certain type
of pass-through entity, or a cash basis taxpayer who so elects, you will be
required to accrue OID on short-term notes on either a straight-line basis or
under the constant-yield method, based on daily compounding. If you are not
required and do not elect to include OID in income currently, any gain you
realize on the sale or retirement of your short-term note will be ordinary
income to the extent of the accrued OID, which will be determined on a straight-
line basis unless you make an election to accrue the OID under the
constant-yield method, through the date of sale or retirement. However, if you
are not required and do not elect to accrue OID on your short-term notes, you
will be required to defer deductions for interest on borrowings allocable to
your short-term notes in an amount not exceeding the deferred income until the
deferred income is realized.

When you determine the amount of OID subject to these rules, you must include
all interest payments on your short-term note, including stated interest, in
your short-term note's stated redemption price at maturity.

FOREIGN CURRENCY DISCOUNT NOTES.  If your discount note is denominated in, or
determined by reference to, a foreign currency, you must determine OID for any
accrual period on your discount note

--------------------------------------------------------------------------------
                                                                             201
<PAGE>   234
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

in the foreign currency and then translate the amount of OID into U.S. dollars
in the same manner as stated interest accrued by an accrual basis United States
holder, as described under "-- United States Holders -- Payments of Interest".
You may recognize ordinary income or loss when you receive an amount
attributable to OID in connection with a payment of interest or the sale or
retirement of your note.

NOTES PURCHASED AT A PREMIUM

If you purchase your note for an amount in excess of its principal amount, you
may elect to treat the excess as amortizable bond premium. If you make this
election, you will reduce the amount required to be included in your income each
year with respect to interest on your note by the amount of amortizable bond
premium allocable to that year, based on your note's yield to maturity. If your
note is denominated in, or determined by reference to, a foreign currency, you
will compute your amortizable bond premium in units of the foreign currency and
your amortizable bond premium will reduce your interest income in units of the
foreign currency. Gain or loss recognized that is attributable to changes in
exchange rates between the time your amortized bond premium offsets interest
income and the time of the acquisition of your note is generally taxable as
ordinary income or loss. If you make an election to amortize bond premium, it
will apply to all debt instruments, other than debt instruments the interest on
which is excludible from gross income, that you hold at the beginning of the
first taxable year to which the election applies or thereafter acquire, and you
may not revoke it without the consent of the Internal Revenue Service. See also
"-- Original Issue Discount -- Election to Treat All Interest as Original Issue
Discount".

PURCHASE, SALE AND RETIREMENT OF THE NOTES

Your tax basis in your note will generally be the U.S. dollar cost, as defined
below, of your note, adjusted by:

- adding any OID or market discount, de minimis original issue discount and de
  minimis market discount; and then

- subtracting any payments on your note that are not qualified stated interest
  payments and any amortizable bond premium applied to reduce the interest on
  your note.

If you purchase your note with foreign currency, the U.S. dollar cost of your
note will generally be the U.S. dollar value of the purchase price on the date
of purchase. However, if you are a cash basis taxpayer, or an accrual basis
taxpayer if you so elect, and your note is traded on an established securities
market, as defined in the applicable Treasury regulations, the U.S. dollar cost
of your note will be the U.S. dollar value of the purchase price on the
settlement date of your purchase.

You will generally recognize gain or loss on the sale or retirement of your note
equal to the difference between the amount you realize on the sale or retirement
and your tax basis in your note. If your note is sold or retired for an amount
in foreign currency, the amount you realize will be the U.S. dollar value of
such amount on:

- the date payment is received, if you are a cash basis taxpayer and the notes
  are not traded on an established securities market, as defined in the
  applicable Treasury regulations;

- the date of disposition, if you are an accrual basis taxpayer; or

- the settlement date for the sale, if you are a cash basis taxpayer, or an
  accrual basis United States holder that so elects, and the notes are traded on
  an established securities market, as defined in the applicable Treasury
  regulations.

--------------------------------------------------------------------------------
 202
<PAGE>   235
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

You will recognize capital gain or loss when you sell or retire your note,
except to the extent attributable to changes in exchange rates as described in
the next paragraph or to accrued but unpaid interest, described above under
"-- Original Issue Discount -- Short-Term Notes" or "-- Market Discount", or
subject to the rules governing contingent payment obligations. Capital gain of a
non-corporate United States holder is generally taxed at a maximum rate of 20%
where the property is held for more than one year.

You must treat any portion of the gain or loss that you recognize on the sale or
retirement of a note as ordinary income or loss to the extent attributable to
changes in exchange rates. However, you only take exchange gain or loss into
account to the extent of the total gain or loss you realize on the transaction.

EXCHANGE OF AMOUNTS IN OTHER THAN U.S. DOLLARS

If you receive foreign currency as interest on your note or on the sale or
retirement of your note, your tax basis in the foreign currency will equal its
U.S. dollar value when the interest is received or at the time of the sale or
retirement. If you purchase foreign currency, you generally will have a tax
basis equal to the U.S. dollar value of the foreign currency on the date of your
purchase. If you sell or dispose of a foreign currency, including if you use it
to purchase notes or exchange it for U.S. dollars, any gain or loss recognized
generally will be ordinary income or loss.

INDEXED AND OTHER NOTES

The applicable prospectus supplement will discuss any special United States
federal income tax rules with respect to contingent foreign currency notes,
notes the payments on which are determined by reference to the value of any
index or stock and other notes that are subject to the rules governing
contingent payment obligations which are not subject to the rules governing
variable rate notes.

BACKUP WITHHOLDING AND INFORMATION REPORTING

PAYMENTS OF PRINCIPAL AND INTEREST.  If you are a non-corporate United States
Holder, information reporting requirements generally will apply to all payments
of principal, any premium and interest on your note and the accrual of OID on a
discount note within the United States, including payments made by wire transfer
from outside the United States to an account you maintain with a fiscal or
paying agent in the United States.

Additionally, backup withholding at a rate of 31% will apply to such payments if
you:

- fail to provide an accurate taxpayer identification number

- are notified by the Internal Revenue Service that you have failed to report
  all interest and dividends required to be shown on your federal income tax
  returns.

If you are a Holder that is not a United States person for federal income tax
purposes, you are generally exempt from backup withholding and information
reporting requirements with respect to payments of principal and interest,
assuming the income is otherwise exempt from United States federal income tax,
provided that you comply with certain certification and identification
procedures in order to prove your exemption.

PROCEEDS FROM THE SALE OF A NOTE.  Payment of the proceeds from the sale of a
note to or through the United States office of a broker may be subject to
information reporting and backup withholding. If, however, you are a Holder that
is not a United States person for federal income tax purposes, you will not be
subject to information reporting or backup withholding if you certify as to your
non-United States status or otherwise establish an exemption. Payment of the
proceeds from the sale of a note

--------------------------------------------------------------------------------
                                                                             203
<PAGE>   236
U.S. TAX CONSIDERATIONS
--------------------------------------------------------------------------------

made to or through a foreign office of a broker generally will not be subject to
information reporting or backup withholding. Information reporting, but not
backup withholding, may apply to such payments, however, if the broker is:

- a United States person;

- a controlled foreign corporation for United States tax purposes;

- a foreign person 50% or more of whose gross income is effectively connected
  with a United States trade or business for a specified three-year period; or

- with respect to payments made after 31 December 2000, a foreign partnership if
  at any time during its tax year

- one or more of its partners are United States persons, as defined in U.S.
  Treasury regulations, who in the aggregate hold more than 50% of the income or
  capital interest in the partnership; or

- the foreign partnership is engaged in a United States trade or business,

unless the broker has documentary evidence in its records that the Holder is a
non-United States person and does not have actual knowledge that the Holder is a
United States person or otherwise establishes an exemption.

Tax Considerations Under The Laws of Switzerland

The tax information set forth below is based on the opinion of Ernst & Young
Ltd., dated 8 November 2000, and has been approved by them for its accuracy. In
this section, we summarize the principal tax consequences under the laws of
Switzerland of owning your note. You should also read the section of your
prospectus supplement concerning taxation under the laws of Switzerland before
you purchase a note, as the tax consequences of owning your note may differ in
some respects than as described in this summary.

We will book the notes in one of our branches that is not a resident in
Switzerland. We do not plan to use the proceeds of the sale of notes in
Switzerland. Therefore, under applicable Swiss law, we do not expect your notes
to be subject to the Swiss federal stamp duty on securities.

Under present law, a Holder of a note who (i) is not a resident of Switzerland,
(ii) during the relevant taxable years has not engaged in a trade or business
through a permanent establishment within Switzerland, and (iii) is not subject
to taxation by Switzerland for any other reason, will not have to pay any
federal, cantonal or municipal income tax either on interest payments with
respect to the note or on gains resulting from the sale of the note. For these
reasons, we believe that payments of interest on your note, if you are not a
resident of Switzerland and are not otherwise subject to taxation in
Switzerland, will not be subject to Swiss income taxes. We also believe that we
will not be required to withhold or deduct any amounts on account of income or
other taxes, withholding or charges imposed by Switzerland or any of its
political subdivisions from payment of principal of, or interest on, your notes,
if you are not a resident of Switzerland and are not otherwise subject to
taxation in Switzerland.

ERISA Considerations

We, UBS Warburg LLC, PaineWebber Incorporated and other of our affiliates may
each be considered a "party in interest" within the meaning of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") or a "disqualified
person" (within the meaning of Section 4975 of the Internal Revenue Code of
1986, as amended (the "Code")) with respect to an employee benefits plan that is
subject to ERISA and/or an individual retirement account that is subject to the
Code ("Plan"). The purchase of notes by a Plan with respect to which UBS Warburg
LLC, Paine Webber Incorporated or any of our affiliates acts as a fiduciary as
defined in Section 3(21) of ERISA and/or Section 4975 of the Code ("Fiduciary")
would constitute a prohibited transaction under ERISA or the Code unless
acquired pursuant to and in accordance with an applicable exemption. The
purchase of notes by a Plan with respect to which UBS Warburg LLC, PaineWebber
Incorporated or any of our affiliates does not act as a Fiduciary but for which
any of the above entities does provide services could also be prohibited, but
one or more exemptions may be applicable. Any person proposing to acquire any
note on behalf of a Plan should consult with counsel regarding the applicability
of the prohibited transaction rules and the applicable exemptions thereto.

Plan of Distribution

PLAN OF DISTRIBUTION FOR THE INITIAL OFFER AND SALE OF NOTES

We, and UBS Warburg LLC and PaineWebber Incorporated, as the agents, have
entered into a distribution agreement with respect to the notes. Subject to
certain conditions, the agents have agreed to use their reasonable efforts to
solicit purchases of the notes. We have the right to accept offers to purchase
notes and may reject any proposed purchase of the notes. The agents may also
reject any offer to purchase notes. We will pay the agents a commission on any
notes sold through the agents. The commission will range from 0.100% to an
estimated maximum of 2.0% of the principal amount of the notes, depending on the
stated maturity of the notes.

We may also sell notes to the agents who will purchase the notes as principal
for their own accounts. In that case, the agents will purchase the notes at a
price equal to the issue price specified in the applicable prospectus
supplement, less a discount. The discount will equal the applicable commission
on an agency sale of notes with the same stated maturity.

The agents may resell any notes they purchase as principal to other brokers or
dealers at a discount, which may include all or part of the discount the agents
received from us. If all the notes are not sold at the initial offering price,
the agents may change the offering price and the other selling terms.

We may also sell notes directly to investors. We will not pay commissions on
notes we sell directly.

The agents, whether acting as agent or principal, may be deemed to be an
"underwriters" within the meaning of the Securities Act of 1933. We have agreed
to indemnify the agents against certain liabilities, including liabilities under
the Securities Act.

If the agents sell notes to dealers who resell to investors and the agents pay
the dealers all or part of the discount or commission they receive from us,
those dealers may also be deemed to be "underwriters" within the meaning of the
Securities Act.

In connection with an offering, the agents may purchase and sell notes in the
open market. These transactions may include short sales, stabilizing
transactions and purchases to cover positions created by short sales. Short
sales involve the sale by an agent of a greater number of securities than they
are required to purchase in an offering. Stabilizing transactions consist of
certain bids or purchases made for the purpose of preventing or retarding a
decline in the market price of the notes while an offering is in progress.

The agents may also impose a penalty bid. This occurs when a particular agent
repays to the agents a portion of the discount received by it because the agents
have repurchased securities sold by or for the account of that agent in
stabilizing or short-covering transactions.

These activities by the agents may stabilize, maintain or otherwise affect the
market price of the notes. As a result, the price of the notes may be higher
than the price that otherwise might exist in the open market. If these
activities are commenced, they may be discontinued by the agents at any time.
These transactions may be effected on an exchange or automated quotation system,
if the securities are listed on that exchange or admitted for trading on that
automated quotation system, or in the over-the-counter market or otherwise.

The purchase price of the notes will be required to be paid in immediately
available funds in New York City, unless otherwise indicated in your prospectus
supplement.

We may appoint agents other than or in addition to UBS Warburg LLC and
PaineWebber Incorporated with respect to the notes. Any other agents will be
named in the applicable prospectus supplements and those agents will enter into
the distribution agreement referred to above. The other agents may be affiliates
or customers of UBS and may engage in transactions with and perform services for
UBS in

the ordinary course of business. UBS Warburg LLC and PaineWebber Incorporated
may resell notes to or through another of our affiliates, as selling agents.

The notes are a new issue of securities, and there will be no established
trading market for any note before its original issue date. We may or may not
list the notes on a securities exchange or quotation system. We have been
advised by UBS Warburg LLC and PaineWebber Incorporated that they intend to make
a market in the notes. However, neither UBS Warburg LLC, PaineWebber
Incorporated nor any of our other affiliates nor any other agent named in your
prospectus supplement that makes a market is obligated to do so and any of them
may stop doing so at any time without notice. No assurance can be given as to
the liquidity or trading market for the notes.

UBS Warburg LLC and PaineWebber Incorporated are affiliates of UBS. Rule 2720 of
the Conduct Rules of the National Association of Securities Dealers, Inc.
imposes certain requirements when an NASD member such as UBS Warburg LLC or
PaineWebber Incorporated distributes an affiliated company's debt securities.
UBS Warburg LLC and PaineWebber Incorporated have advised UBS that this offering
will comply with the applicable requirements of Rule 2720.

UBS Warburg LLC and PaineWebber Incorporated will not confirm initial sales to
accounts over which it exercises discretionary authority without the prior
written approval of the customer.

MARKET-MAKING RESALES BY AFFILIATES

This prospectus may be used by UBS, UBS Warburg LLC, PaineWebber Incorporated or
any other affiliate of UBS in connection with offers and sales of the notes in
market-making transactions. In a market-making transaction, each of UBS, UBS
Warburg LLC, PaineWebber Incorporated or any other affiliate of UBS may resell a
note it acquires from other holders, after the original offering and sale of the
note. Resales of this kind may occur in the open market or may be privately
negotiated at prevailing market prices at the time of resale or at related or
negotiated prices. In these transactions, UBS, UBS Warburg LLC, PaineWebber
Incorporated or any other affiliate of UBS may act as principal or agent,
including as agent for the counterparty in a transaction in which it acts as
principal, or as agent for both counterparties in a transaction in which it does
not act as principal. UBS, UBS Warburg LLC, PaineWebber Incorporated or any
other affiliate of UBS may receive compensation in the form of discounts and
commissions, including from both counterparties in some cases.

UBS does not expect to receive any proceeds from market-making transactions
other than those it undertakes on its own. UBS does not expect that UBS Warburg
LLC, PaineWebber Incorporated or any other affiliate that engages in these
transactions will pay any proceeds from its market-making resales to UBS.

Information about the trade and settlement dates, as well as the purchase price,
for a market-making transaction will be provided to the purchaser in a separate
confirmation of sale.

Unless UBS or an agent informs you in your confirmation of sale that your note
is being purchased in its original offering and sale, you may assume that you
are purchasing your note in a market-making transaction.

MATTERS RELATING TO INITIAL OFFERING AND MARKET-MAKING RESALES

UBS Warburg LLC and PaineWebber Incorporated do not expect the amount of notes
held, as a result of market-making resales, by accounts over which it exercises
discretionary authority to exceed, at any time, five percent of the aggregate
initial offering price (that is, $100,000,000) of all of the notes. In
compliance with NASD guidelines, the maximum commission or discount to be
received by any NASD member or independent broker dealer may not exceed 8% of
the aggregate principal amount of the notes offered pursuant to this prospectus;
however, it is anticipated that the maximum commission or discount to be
received in any particular offering of notes will be significantly less than
this amount.

In this prospectus, the term "this offering" means the initial offering of the
notes made in connection with their original issuance. This term does not refer
to any subsequent resales of notes in market-making transactions.

Validity of the Notes

In connection with the commencement of our Series A medium-term note program,
the validity of the notes was passed upon by Sullivan & Cromwell as to matters
of New York law and by Bar & Karrer as to matters of Swiss law. These opinions
were based on assumptions about future actions required to be taken by UBS and
the trustee in connection with the issuance and sale of each note, about the
specific terms of each note and about other matters that may affect the validity
of the notes but which could not be ascertained on the date of those options.

Limitation on Enforcement of U.S. Laws Against UBS, Its Management and Others

UBS is a Swiss bank. Many of its directors and executive officers, including all
of the persons who signed the registration statement of which this prospectus is
a part, and certain experts named in this prospectus, are resident outside the
United States, and all or a substantial portion of our assets and the assets of
such persons are located outside the United States. As a result, it may be
difficult for you to serve legal process on UBS or its management or have any of
them appear in a U.S. court. We have been advised by Bar & Karrer, Swiss counsel
to UBS, that there is doubt as to enforceability in Switzerland, in original
actions or in actions for enforcement of judgment of U.S. courts, of liabilities
based solely on the federal securities laws of the United States.

Presentation of Financial Information

UBS's financial statements have been prepared in accordance with International
Accounting Standards and are denominated in Swiss francs, or "CHF," the legal
tender of Switzerland. For convenience, 31 December 1999 CHF amounts have been
translated into United States dollars, or "$," at the rate of CHF 1=$0.6277,
which was the noon buying rate on 31 December 1999, and 30 June 2000 CHF amounts
have been translated into United States dollars at the rate of CHF 1=$0.6129,
which was the noon buying rate on 30 June 2000. This translation should not be
construed as a representation that the Swiss franc amounts actually denote such
United States dollar amounts or have been, could have been or could be,
converted into United States dollars at the rate indicated.

The table below sets forth, for the periods and dates indicated, information
concerning the noon buying rate for the Swiss franc, expressed in United States
dollars per one Swiss franc. The "noon buying rate" is the rate in New York City
for cable transfers in foreign currencies as certified for customs purposes by
the Federal Reserve Bank of New York.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Group Executive Board UBS AG:

We have audited the accompanying consolidated balance sheets of UBS AG and
subsidiaries as of 31 December 1999 and 1998, and the related consolidated
statements of income, cash flows and changes in shareholders' equity for each of
the three years in the period ended 31 December 1999. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. These standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, based on our audits, the consolidated financial statements
referred to above present fairly, in all material respects, the consolidated
financial position of UBS AG as of 31 December 1999 and 1998, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended 31 December 1999, in conformity with
International Accounting Standards ("IAS") and comply with Swiss Law.

IAS vary in certain significant respects from accounting principles generally
accepted in the United States of America. Application of accounting principles
generally accepted in the United States of America would have affected
shareholders' equity as of 31 December 1999 and 1998 and the results of
operations for the two years then ended to the extent summarized in Note 42 of
the Notes to the Financial Statements.

Basel, 8 March 2000, except for Note 38,
  as to which the date is 18 April 2000
  and Note 1(t) as to which
  the date is 17 August 2000

                                   UBS GROUP

                       NOTES TO THE FINANCIAL STATEMENTS

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  a) Basis of accounting

UBS AG and subsidiaries ("UBS" or the "Group") provides a broad range of
financial services such as advisory, underwriting, financing, market making,
asset management, brokerage, and retail banking on a global level. The Group was
formed on 29 June 1998 when Swiss Bank Corporation and Union Bank of Switzerland
merged. The merger was accounted for using the pooling of interests method of
accounting. Due to the merger, the Group harmonized its accounting policies,
which have been retrospectively applied for the presentation of comparative
information.

The Group adopted new International Accounting Standards ("IAS") and changed the
presentation of certain financial information effective 1 January 2000. The
consolidated financial statements have been restated, where practicable, to give
retroactive effect to these changes -- see t) below.

The consolidated financial statements are stated in Swiss francs, the currency
of the country in which UBS AG is incorporated. They are prepared in accordance
with International Accounting Standards. In preparing the consolidated financial
statements, management is required to make estimates and assumptions that affect
the amounts reported. Actual results could differ from such estimates and the
differences may be material to the consolidated financial statements.

  b) Consolidation

The consolidated financial statements comprise those of the parent company (UBS
AG), its subsidiaries and its special purpose entities, presented as a single
economic entity. Subsidiaries and special purpose entities which are directly or
indirectly controlled by the Group are consolidated. Subsidiaries acquired are
consolidated from the date control passes. Companies which are acquired and held
with a view to their subsequent disposal are recorded as financial investments.

The effects of intra-group transactions are eliminated in preparing the Group
financial statements, except for certain intercompany derivatives for which
hedge accounting is used.

Equity and net income attributable to minority interests are shown separately in
the balance sheet and income statement respectively.

  c) Offsetting

Assets and liabilities are offset only when the Group has a legal right to
offset amounts with the same counterparty and transactions are expected to be
settled on a net basis.

  d) Trade date/settlement date accounting

When the Group becomes party to a contract in its trading activities it
recognizes from that date ("trade date") any unrealized profits and losses
arising from revaluing that contract to fair value. These unrealized profits and
losses are recognized in the income statement.

On a date subsequent to the trade date, the terms of spot and forward trading
transactions are fulfilled ("settlement date") and a resulting financial asset
or liability is recognized on the balance sheet at the fair value of the
consideration given or received.

  e) Foreign currency translation

Foreign currency transactions are recorded at the rate of exchange on the date
of the transaction. At the balance sheet date, monetary assets and liabilities
denominated in foreign currencies are reported

--------------------------------------------------------------------------------
                                                                            F- 7
<PAGE>   252
                                   UBS GROUP

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

using the closing exchange rate. Exchange differences arising on the settlement
of transactions at rates different from those at the date of the transaction,
and unrealized foreign exchange differences on unsettled foreign currency
monetary assets and liabilities, are recognized in the income statement.

Assets and liabilities of foreign entities are translated at the exchange rates
at the balance sheet date, while income statement items and cash flows are
translated at average rates over the year. Differences resulting from the use of
these different exchange rates are recognized directly in foreign currency
translation within shareholders' equity.

  f) Business and geographical segments

The Group is organized on a worldwide basis into five major operating divisions
and Corporate Center. These divisions are the basis upon which the Group reports
its primary segment information.

Segment revenue, segment expenses and segment performance include transfers
between business segments and between geographical segments. Such transfers are
accounted for at competitive prices charged to unaffiliated customers for
similar services.

  g) Securities borrowing and lending

Securities borrowed and lent that are collateralized by cash are included in the
balance sheet at amounts equal to the collateral advanced or received.

Income arising from the securities lending and borrowing business is recognized
in the income statement on an accrual basis.

  h) Repurchase and reverse repurchase transactions

The Group enters into purchases of securities under agreements to resell and
sales of securities under agreements to repurchase substantially identical
securities. Securities which have been sold subject to repurchase agreements
continue to be recognized in the balance sheet and are measured in accordance
with the accounting policy for trading balances or financial assets as
appropriate. The proceeds from sale of these securities are treated as
liabilities and included in repurchase agreements.

Securities purchased subject to commitments to resell at a future date are
treated as loans collateralized by the security and are included in reverse
repurchase agreements.

Interest earned on reverse repurchase agreements and interest incurred on
repurchase agreements is recognized as interest income and interest expense
respectively over the life of each agreement.

  i) Trading portfolio

The trading portfolio consists of debt and equity securities as well as of
precious metals held to meet the financial needs of our customers and to take
advantage of market opportunities. The trading portfolio is carried at fair
value. Short positions in securities are reported as trading portfolio
liabilities. Realized and unrealized gains and losses, net of related
transaction expenses, are recognized as net trading income. Net trading income
also includes interest and dividend income on trading assets as well as the
funding costs for holding these positions.

  j) Loans and allowance for credit losses

Loans are initially recorded at cost. For loans originated by the Group, the
cost is the amount lent to the borrower. For loans acquired from a third party
the cost is the fair value at the time of acquisition.

--------------------------------------------------------------------------------
F- 8
<PAGE>   253
                                   UBS GROUP

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

Interest income on an unimpaired loan is recognized on an accrual basis.
Interest includes the amount of amortization of any discount or premium between
the cost of a loan and its amount at maturity and the amortization of any loan
fees and costs.

The allowance for credit losses provides for risks of losses inherent in the
credit extension process, including loans and lending-related commitments. Such
commitments include letters of credit, guarantees and commitments to extend
credit. Counterparties are individually rated and periodically reviewed and
analyzed. The allowance is adjusted for impairments identified on a loan-by-loan
basis. If there are indications that there are significant probable losses in
the portfolio that have not specifically been identified, allowances would also
be provided for on a portfolio basis.

Impairments in loans are recognized when it becomes probable that the Group will
not be able to collect all amounts due according to the contractual terms of the
loans. The carrying amounts of the loans are reduced to their estimated
realizable value through a specific allowance. The impairment is recognized as
an expense for the period. Loans are stated at their principal amount net of any
allowance for credit losses.

This management process has resulted in the following components of the overall
allowance:

          Counterparty-specific: Probable losses from individual credit
     exposures are evaluated based upon the borrower's character, overall
     financial condition, resources and payment record; the prospects for
     support from any financially responsible guarantors; and, if appropriate,
     the realizable value of any collateral. Impairment is measured and
     allowances are established based on discounted expected cash flows.

          Country-specific: Probable losses resulting from exposures in
     countries experiencing political and transfer risk, countrywide economic
     distress, or problems regarding the legal enforceability of contracts are
     assessed using country specific scenarios and taking into consideration the
     nature of the individual exposures and their importance for the economy.
     Specific country allowances exclude exposures addressed in
     counterparty-specific allowances.

          Specific reserve pools: Specific risk reserve pools were established
     in 1996 to absorb probable losses not specifically identified at that time,
     but which experience indicated were present in the portfolio. These pools
     subsequently have been applied to specific loans based on the analysis of
     individual credit exposures. The Group does not believe there is a current
     need for such allowances.

A loan is classified as non-performing when the contractual payments of
principal and/or interest are in arrears for 90 days or more. After the 90 day
period the recognition of interest income ceases and a charge is recognized for
the unpaid and accrued interest receivable.

A write-off is made when all or part of a loan is deemed uncollectible or in the
case of debt forgiveness. Write-offs are charged against previously established
allowances and reduce the principal amount of a loan.

  k) Financial investments

Financial investments are debt and equity securities held for the accretion of
wealth through distributions, such as interest and dividends, and for capital
appreciation. Financial investments also include real estate held for sale.

Debt securities held to maturity are carried at amortized cost. If necessary,
the carrying amount is reduced to its estimated realizable value. Interest
income on debt securities, including amortization of premiums and discounts, is
recognized on an accrual basis and reported as net interest income.

--------------------------------------------------------------------------------
                                                                            F- 9
<PAGE>   254
                                   UBS GROUP

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

Financial investments held for sale are carried at the lower of cost or market
value. Reductions to market value and reversals of such reductions as well as
gains and losses on disposal are included in other income. Interest earned and
dividends received are included in net interest income.

Private equity investments are carried at cost less write-downs for impairments
in value. Reductions of the carrying amount and reversals of such reductions as
well as gains and losses on disposal are included in other income.

  l) Investments in associates

Investments in associates in which the Group has a significant influence are
accounted for by the equity method. Investments in which the Group has a
significant influence, but which are acquired and held with a view to their
subsequent disposal, are included in financial investments (see the reference to
private equity investments in the paragraph above).

Investments in companies where the parent company does not hold a significant
influence are recorded at cost less value adjustments for less than temporary
declines in value.

  m) Property and equipment

Property and equipment includes land, buildings, furnishings, fixtures,
leasehold improvements, computer, telecommunications and other equipment.
Property and equipment is carried at cost less accumulated depreciation and is
periodically reviewed for impairment.

Property and equipment is depreciated on a straight-line basis over their
estimated useful lives as follows:

<TABLE>
<S>  <C>                       <C>
-    Buildings                 Not exceeding 50 years
-    Furnishings and           Not exceeding 10 years
     fixtures
-    Leasehold improvements    Not exceeding 10 years
-    Equipment                 Not exceeding 5 years
</TABLE>

  n) Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value
of the Group's share of the net assets of the acquired subsidiary or associate
at the date of acquisition. Goodwill and intangibles resulting from the
acquisition of client franchises are recognized as an asset and are amortized
using the straight-line basis over their estimated useful economic life, not
exceeding 20 years. At each balance sheet date, goodwill is reviewed for
indications of impairment. If such indications exist an analysis is performed
including an assessment of future cash flows to determine if a write-down is
necessary.

Goodwill and fair value adjustments arising on the acquisition of foreign
subsidiaries are treated as local currency balances and are translated into
Swiss francs at the closing rate at subsequent balance sheet dates.

  o) Income taxes

Income tax payable on profits, based on the applicable tax laws in each
jurisdiction, is recognized as an expense in the period in which profits arise.
The tax effects on income tax losses available for carry-forward are recognized
as an asset when it is probable that future taxable profit will be available
against which those losses can be utilized.

--------------------------------------------------------------------------------
F- 10
<PAGE>   255
                                   UBS GROUP

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

Deferred tax liabilities are recognized for temporary differences between the
carrying amounts of assets and liabilities in the Group balance sheet and their
amounts as measured for tax purposes, which will result in taxable amounts in
future periods. Deferred tax assets are recognized for temporary differences
which will result in deductible amounts in future periods, but only to the
extent it is probable that sufficient taxable profits will be available against
which these differences can be utilized.

Deferred tax assets and liabilities are measured at the tax rates that are
expected to apply to the period in which the asset will be realized or the
liability will be settled.

Current and deferred tax assets and liabilities are offset when they arise from
the same tax reporting group and relate to the same tax authority and when the
legal right to offset exists.

  p) Own shares, own bonds and derivatives on own shares

In the normal course of its trading and market making activities, the Group buys
and sells its own shares, own bonds and derivatives on its own shares. In 1997,
these instruments were held in the trading portfolio similar to other trading
instruments, and carried at fair value. Changes in fair value and dividends
received on UBS AG shares and interest on its own bonds in the trading portfolio
were recognized as net trading income (See Note t).

The Group also holds its own shares for non-trading purposes, for instance
employee compensation schemes and other strategic purposes. These shares are
recorded within treasury shares and are deducted from shareholders' equity. The
difference between the proceeds of the sale of treasury shares and their cost
basis is recognized in share premium. Dividends relating to treasury shares are
not recognized.

  q) Retirement benefits

The Group sponsors a number of retirement benefit plans for its employees
worldwide. These plans include both defined benefit and defined contribution
plans and various other retirement benefits such as post-employment medical
benefit. As of 1 January 1999, the Group adopted IAS 19, Employee Benefits
(revised 1998) ("IAS 19") to account for such plans. Under IAS 19, Group
contributions to defined contribution plans are expensed when employees have
rendered services in exchange for such contributions, generally in the year of
contribution.

In accordance with IAS 19, the Group uses the projected unit credit actuarial
method to determine the present value of its defined benefit obligations and the
related current service cost and, where applicable, past service cost.

The principal actuarial assumptions made by the actuary are set out in Note 35.

The Group recognizes a portion of its actuarial gains and losses as income or
expenses if the net cumulative unrecognized actuarial gains and losses at the
end of the previous reporting period exceeded the greater of:

          a) 10% of the present value of the defined benefit obligation at that
             date (before deducting plan assets); and

          b) 10% of the fair value of any plan assets at that date.

The unrecognized actuarial gains and losses exceeding the greater of the two
values are recognized in the income statement over the expected average
remaining working lives of the employees participating in the plans.

--------------------------------------------------------------------------------
                                                                           F- 11

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

  r) Derivative instruments

Derivative instruments are carried at fair value. Fair values are obtained from
quoted market prices, discounted cash flow models and option pricing models as
appropriate. The fair values of derivative instruments are shown in the balance
sheet as positive and negative replacement values. Realized and unrealized gains
and losses are recognized in net trading income. Valuation adjustments to cover
credit and market liquidity risks have been made.

Transactions in derivative instruments entered into for hedging of non-trading
positions are recognized in the income statement on the same basis as to the
underlying item being hedged.

  s) Comparability

Certain amounts have been reclassified from previous years to conform to the
1999 presentation.

The prior year financial statements reflect the requirements of the following
revised or new International Accounting Standards, which the Group implemented
in 1999:

<TABLE>
<S>  <C>       <C>
-    IAS 1     Presentation of Financial Statements
-    IAS 14    Segment Reporting
-    IAS 17    Accounting for Leases
-    IAS 19    Employee Benefits
-    IAS 36    Impairment of Assets.
</TABLE>

The implementation of the above standards had no material impact for the Group.

  t) Retroactive application of accounting changes adopted 1 January 2000

The consolidated financial statements as of and for the years ended 31 December
1999 and 1998 have been restated to reflect retroactively changes in accounting
policy arising from newly applicable IAS and changes in presentation adopted 1
January 2000, as discussed below. 1997 financial information has not been
restated due to unavailability of certain pre-merger data and different
organizational structures.

The following notes to the financial statements also have been revised to
reflect the changes referred to in this Note: Notes 2, 3, 4, 6, 10, 14, 15, 25,
27, 33, 34, 41, 42 and 43.

     Standing Interpretations Committee ("SIC") 16, Share Capital -- Reacquired
Own Equity Instruments (Treasury Shares)

In May 1999, the International Accounting Standards Committee ("IASC") issued
Interpretation SIC 16, Share Capital -- Reacquired Own Equity Instruments
(Treasury Shares) which the Group adopted as of 1 January 2000. The
Interpretation provides guidance for the recognition, presentation, and
disclosure of Treasury shares. SIC 16 applies to own shares and derivatives on
own shares held for trading and non-trading purposes. SIC 16 requires own shares
and derivatives on own shares to be presented as Treasury shares and deducted
from Shareholders' equity. Gains and losses relating to the sale of own shares
and derivatives on own shares are not recognized in the income statement but
rather as a change in Shareholders' equity.

As a result of the retroactive application of Interpretation SIC 16, net trading
income was reduced by CHF 196 million and CHF 81 million, and income tax expense
was reduced by CHF 49 million and CHF 23 million for the years ended 31 December
1999 and 1998, respectively; these amounts were recorded in shareholders'
equity. Shareholders' equity and total assets were reduced by CHF 4,227 million
and CHF 3,601 million as of 31 December 1999 and 1998, respectively, to reflect
the

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

reclassification of own shares and derivatives on own shares held at those
dates. Of the CHF 4,227 million for 31 December 1999, CHF 4,561 million was a
reduction in trading portfolio assets and the remaining CHF 334 million was an
increase in positive replacement values. Of the CHF 3,601 million for 31
December 1998, CHF 3,409 million was a reduction to trading portfolio assets and
the remaining CHF 192 million was a reduction to positive replacement values. In
addition, shareholders' equity was adjusted as of 1 January 1998.

     Offsetting of Amounts Related to Certain Contracts

In order to improve comparability with its main competitors, the Group has
offset positive and negative replacement values and reverse repurchase
agreements and repurchase agreements with the same counter-party for
transactions covered by legally enforceable master netting agreements. Positive
and negative replacement values have been reduced by CHF 66,136 million and CHF
79,233 million as of 31 December 1999 and 1998, respectively. Reverse repurchase
and repurchase agreements have been reduced by CHF 12,322 million as of 31
December 1999.

     Interest and Dividend Income and Expense on Trading Assets and Liabilities

In prior periods, interest and dividend income and expense on trading assets and
liabilities were included in net trading income. In order to improve
comparability with its main competitors, the Group has included interest and
dividend income on trading assets and interest expense on trading liabilities in
interest income and interest expense, respectively, and has discontinued the
allocation of funding costs to net trading income.

Interest income was increased by CHF 17,281 million and CHF 14,607 million for
the years ended 31 December 1999 and 1998, respectively. Interest expense was
increased by CHF 17,728 million and CHF 16,251 million for the years ended 31
December 1999 and 1998, respectively. Net trading income was increased by CHF
447 million and CHF 1,644 million for the years ended 31 December 1999 and 1998,
respectively.

     Tax Expense

Capital taxes were included in tax expense. The Group has reclassified CHF 80
million and CHF 118 million in Capital taxes from tax expense to General and
administrative expenses for the years ended 31 December 1999 and 1998,
respectively.

     Segment Information

In the first half of 2000, the Group reorganized its business divisions. The
segment reporting for the year ended 31 December 1999 and 1998 has been restated
to reflect the new Group structure.

The following IAS were adopted as of 1 January 2000, but this adoption had no
material impact on the prior periods presented herein.

     IAS 37, Provisions, Contingent Liabilities and Contingent Assets

In July 1998, the IASC issued IAS 37, Provisions, Contingent Liabilities and
Contingent Assets, which is required to be adopted for the Group's financial
statements as of 1 January 2000. The Standard provides accounting and disclosure
requirements for contingent liabilities and contingent assets. IAS 37 also
provides recognition and measurement requirements for provisions.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

     IAS 38, Intangible Assets

In July 1998, the IASC issued IAS 38, Intangible Assets, which is required to be
adopted prospectively for the Group's financial statements as of 1 January 2000.
The Standard requires the capitalization and amortization of intangible assets,
if it is probable that the future economic benefits that are attributable to the
assets will flow to the enterprise and the cost of the asset can be measured
reliably. The amortization period for recognized intangible assets should not
exceed 20 years. If adopted in 1999 this standard would have increased operating
profit by approximately CHF 300 million.

     IAS 10 (revised), Events After the Balance Sheet Date

In May 1999, the IASC issued IAS 10 (revised), Events After the Balance Sheet
Date, which is required to be adopted for the Group's financial statements as of
1 January 2000. IAS 10 (revised) establishes requirements for the recognition
and disclosure of events after the balance sheet date.

  u) Recent accounting standards not yet adopted

     IAS 39, Recognition and Measurement of Financial Instruments

In December 1998, the IASC issued IAS 39, Recognition and Measurement of
Financial Instruments, which is required to be adopted for the Group's financial
statements as of 1 January 2001 on a prospective basis. The Standard provides
comprehensive guidance on accounting for financial instruments. Financial
instruments include conventional financial assets and liabilities and
derivatives. IAS 39 requires that all financial instruments should be recognized
on the balance sheet. Most financial instruments should be carried at fair
value. IAS 39 also establishes hedge accounting criteria and guidelines. While
the specific impact on earnings and financial position of IAS 39 has not been
determined, the activities that will be most affected by the new Standard have
been identified. Specifically, the use of derivatives to hedge loans, deposits,
and issuance of debt, primarily hedge of interest rate risk, will be affected by
IAS 39. Management is currently evaluating the impact of IAS 39. The actual
assessment of the impact of IAS 39 on the Group's earnings and financial
position will be based on the 1 January 2001 financial position, among other
things, in accordance with the Standard.

NOTE 2 SEGMENT REPORTING BY BUSINESS GROUP

The business group results have been presented on a management reporting basis.
Consequently, internal charges and transfer pricing adjustments have been
reflected in the performance of each business. The basis of the reporting
reflects the management of the business within the Group. Total revenue includes
income which is directly attributable to a business group whether from sales to
external customers or from transactions with other segments. Revenue sharing
agreements are used to allocate external customer revenues to a business group

(1) In order to show the relevant business group performance over time, adjusted
    expected loss figures rather than the net credit loss expense are reported
    for all business groups. The statistically derived adjusted expected losses
    reflect the inherent counterparty and country risks in the respective
    portfolios. The difference between the statistically derived adjusted
    expected loss figures and the net credit loss expense for financial
    reporting purposes is reported in the Corporate Center. The divisional
    breakdown of the net credit loss expense for financial reporting purposes of
    CHF 956 million for the year ended 31 December 1999 is as follows: UBS
    Switzerland CHF 985 million, UBS Warburg CHF (20) million, Corporate Center
    CHF (9) million.

(2) The 1999 figures have been restated to reflect the new Group structure and
    retroactive changes in accounting policy and changes in presentation (see
    Note 1: Basis of Accounting).

(3) The funding surplus/requirement is reflected in each business group and
    adjusted in Corporate Center.

(1) Basically the same methodology as for the year 1998 segment reporting is
    applied. Due to the unavailability of certain pre-1998 merger data and
    different organizational structures, the divisional breakdown of the
    financially booked net credit loss expense is not available.

The 1997 results do not take into account the 1998 merger provision and the
impact of the 1998 merger on taxes. The net loss for the Group including these
items was CHF (667) million. Due to the unavailability of certain pre-merger
(1998 merger) data, 1997 assets and liabilities by business group are not
presented.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 3 SEGMENT REPORTING BY GEOGRAPHICAL LOCATION

The geographical analysis of total assets is based on customer domicile whereas
operating income and capital investment is based on the location of the office
in which the transactions and assets are recorded. Because of the global nature
of financial markets the Group's business is managed on an integrated basis
worldwide, with a view to profitability by product line. The geographical
analysis of operating income, total assets, and capital investment is provided
in order to comply with International Accounting Standards, and does not reflect
the way the Group is managed. Management believes that analysis by business
division, as shown in Note 2 to these financial statements, is a more meaningful
representation of the way in which the Group is managed.
