                     THE FUNDS AND THEIR INVESTMENT POLICIES

         No fund's  investment  objective  may be  changed  without  shareholder
approval.  Except where noted, the other investment policies of each fund may be
changed by the board without shareholder  approval.  As with other mutual funds,
there is no assurance that a fund will achieve its investment objective.

         MONEY MARKET PORTFOLIO'S investment objective is maximum current income
consistent with liquidity and conservation of capital.  The fund invests in high
quality money market  instruments  that have,  or are deemed to have,  remaining
maturities of 13 months or less.  Money market  instruments  are short-term debt
obligations  and similar  securities.  These  instruments  include (1) U.S.  and
foreign  government  securities,  (2) obligations of U.S. and foreign banks, (3)
commercial paper and other short-term corporate  obligations of U.S. and foreign
corporations,   partnerships,   trusts  and  similar  entities,  (4)  repurchase
agreements and (5) investment company securities.  Money market instruments also
include  longer term bonds that have  variable  interest  rates or other special
features that give them the financial  characteristics  of short-term  debt. The
fund may purchase  participation  interests in any of the securities in which it
is  permitted  to invest.  Participation  interests  are pro rata  interests  in
securities  held  by  others.  The  fund  maintains  a  dollar-weighted  average
portfolio maturity of 90 days or less.

         Money   Market   Portfolio   may  invest  in   obligations   (including
certificates  of  deposit,  bankers'  acceptances,  time  deposits  and  similar
obligations)  of U.S. and foreign banks only if the institution has total assets
at the time of purchase in excess of $1.5  billion.  The fund's  investments  in
non-negotiable  time deposits of these institutions will be considered  illiquid
if they have maturities greater than seven days.

         Money  Market  Portfolio  may  purchase  only  those  obligations  that
Mitchell  Hutchins  determines,  pursuant  to  procedures  adopted by the board,
present minimal credit risks and are "First Tier  Securities" as defined in Rule
2a-7 under the Investment Company Act of 1940, as amended  ("Investment  Company
Act").  A First  Tier  Security  is either (1) rated in the  highest  short-term
rating  category  by at  least  two  nationally  recognized  statistical  rating
organizations  ("rating  agencies"),  (2) rated in the highest short-term rating
category by a single  rating  agency if only that rating agency has assigned the
obligation a short-term rating, (3) issued by an issuer that has received such a
short-term  rating with respect to a security that is comparable in priority and
security,  (4) subject to a guarantee  rated in the  highest  short-term  rating
category  or issued by a guarantor  that has  received  the  highest  short-term
rating for a comparable  debt  obligation  or (5)  unrated,  but  determined  by
Mitchell Hutchins to be of comparable quality.

         Subsequent  to its  purchase by Money  Market  Portfolio,  an issue may
cease to be rated or its rating  may be  reduced.  If a  security  in the fund's
portfolio  ceases to be a First Tier  Security  (as  defined  above) or Mitchell
Hutchins  becomes  aware that a security  has received a rating below the second
highest  rating by any rating agency,  Mitchell  Hutchins and, in certain cases,
the  board,  will  consider  whether  the  fund  should  continue  to  hold  the
obligation.  A First Tier Security rated in the highest short-term category by a
single rating agency at the time of purchase that subsequently receives a rating
below the highest rating category from a different rating agency may continue to
be considered a First Tier Security.

         Money  Market  Portfolio  may  purchase   variable  and  floating  rate
securities  with  remaining  maturities  in excess  of 13 months  issued by U.S.
government agencies or  instrumentalities  or guaranteed by the U.S. government.
In addition,  the fund may purchase  variable and floating  rate  securities  of
other  issuers.  The yields on these  securities  are  adjusted  in  relation to
changes in specific rates, such as the prime rate, and different  securities may
have different  adjustment  rates.  Certain of these  obligations carry a demand
feature that gives the fund the right to tender them back to a specified  party,
usually  the  issuer or a  remarketing  agent,  prior to  maturity.  The  fund's
investment in these  securities must comply with  conditions  established by the
Securities and Exchange Commission ("SEC") under which they may be considered to
have remaining  maturities of 13 months or less. The fund will purchase variable
and floating rate securities of non-U.S.  government issuers that have remaining
maturities of more than 13 months only if the securities are subject to a demand
feature exercisable within 13 months or less.

         Generally, Money Market Portfolio may exercise demand features (1) upon
a default  under the  terms of the  underlying  security,  (2) to  maintain  its
portfolio in accordance with its investment objective and policies or applicable
legal or regulatory  requirements  or (3) as needed to provide  liquidity to the
fund in  order  to meet  redemption  requests.  The  ability  of a bank or other
financial  institution  to  fulfill  its  obligations  under a letter of credit,

                                       2
<PAGE>

guarantee or other liquidity arrangement might be affected by possible financial
difficulties  of its borrowers,  adverse  interest rate or economic  conditions,
regulatory  limitations or other factors.  The interest rate on floating rate or
variable rate securities ordinarily is readjusted on the basis of the prime rate
of the bank that originated the financing or some other index or published rate,
such as the 90-day U.S.  Treasury  bill rate,  or is otherwise  reset to reflect
market rates of interest.  Generally,  these interest rate adjustments cause the
market value of floating  rate and variable rate  securities  to fluctuate  less
than the market value of fixed-rate securities.

         Variable rate securities  include  variable amount master demand notes,
which are unsecured  redeemable  obligations  that permit  investment of varying
amounts at  fluctuating  interest rates under a direct  agreement  between Money
Market  Portfolio  and an issuer.  The  principal  amount of these  notes may be
increased  from time to time by the parties  (subject to specified  maximums) or
decreased  by the fund or the issuer.  These notes are payable on demand and may
or may not be rated.

         Money  Market  Portfolio  generally  may  invest no more than 5% of its
total assets in the securities of a single issuer (other than securities  issued
by the U.S. government, its agencies or instrumentalities), except that the fund
may invest up to 25% of its total  assets in First Tier  Securities  of a single
issuer for a period of up to three  business  days.  The fund may purchase  only
U.S. dollar denominated obligations of foreign issuers.

         Money  Market  Portfolio  may  invest  up to 10% of its net  assets  in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may borrow  from banks or  through  reverse  repurchase
agreements for temporary or emergency purposes,  but not in excess of 10% of its
total  assets.  The fund  may  invest  in the  securities  of  other  investment
companies.

         HIGH GRADE FIXED INCOME  PORTFOLIO'S  primary  investment  objective is
current income;  capital appreciation is a secondary investment  objective.  The
fund invests in U.S. government bonds, including those backed by mortgages.  The
fund may also  invest in  corporate  bonds and may invest up to 25% of its total
assets  in  mortgage-  and  asset-backed  securities  of  private  issuers.  The
corporate  bonds in which the fund may invest  consist  primarily  of bonds that
are,  at the  time of  purchase,  rated  within  one of the two  highest  grades
assigned by Standard & Poor's,  a division of The  McGraw-Hill  Companies,  Inc.
("S&P"), or Moody's Investors Service Inc. ("Moody's"), except that the fund may
invest up to 35% of its total assets in investment grade bonds that are rated at
the time of  purchase  lower  than the two  highest  grades  assigned  by S&P or
Moody's.  The fund may invest in bonds that are assigned  comparable  ratings by
another rating agency and unrated bonds that Mitchell Hutchins determines are of
comparable  quality to rated  securities in which the fund may invest.  The fund
may invest up to 15% of its total assets in U.S. dollar  denominated  bonds sold
in the United States by foreign  issuers  (Yankee  bonds) if the  securities are
traded on recognized U.S. exchanges or in the U.S. over-the-counter market.

         No more than 55% of High Grade Fixed  Income  Portfolio's  total assets
may  be  represented  by  U.S.   Treasury   obligations  to  assure  the  fund's
satisfaction of the diversification requirements imposed by the Internal Revenue
Code on segregated  asset  accounts used to fund  variable  annuity  and/or life
insurance contracts. These diversification requirements must be satisfied by the
fund as an investment vehicle underlying the segregated asset accounts.

         High  Grade  Fixed  Income  Portfolio  may  invest up to 10% of its net
assets in illiquid securities. The fund may purchase securities on a when-issued
or  delayed  delivery  basis.  The fund may lend  its  portfolio  securities  to
qualified  broker-dealers or institutional  investors in an amount up to 33 1/3%
of its  total  assets.  The fund  may  borrow  from  banks  or  through  reverse
repurchase  agreements  up to 33 1/3%  of its  total  assets  for  temporary  or
emergency  purposes.  The fund may invest in the securities of other  investment
companies and may sell short "against the box."

         STRATEGIC FIXED INCOME PORTFOLIO'S investment objective is total return
with low  volatility.  The fund's  investments  are  managed  by a  sub-adviser,
Pacific Investment  Management  Company ("PIMCO").  The fund invests in bonds of
varying  maturities but normally  maintains a dollar-weighted  average portfolio
duration  between three and eight years.  Under normal  circumstances,  the fund
invests  at least 65% of its  total  assets in fixed  income  securities,  which
include U.S.  government and foreign government bonds (including bonds issued by
supranational and quasi-governmental  entities and mortgage-backed  securities),
corporate   bonds  of  U.S.  and  foreign  issuers   (including   mortgage-  and

                                       3
<PAGE>

asset-backed  securities of private issuers),  convertible  securities,  foreign
currency  exchange-related  securities,  loan participations and assignments and
money market instruments.  The fund's investments in mortgage-backed  securities
of private issuers are limited to 35% of its total assets and its investments in
loan participations and assignments are limited to 5% of its net assets.

         Strategic Fixed Income Portfolio  invests primarily in investment grade
bonds  but may  invest up to 20% of its total  assets in  securities,  including
convertible  securities,  that are not investment grade but are rated at least B
by S&P or Moody's,  assigned a comparable rating by another rating agency or, if
unrated, determined by the sub-adviser to be of comparable quality. The fund may
invest  up to 20%  of  its  total  assets  in a  combination  of  Yankee  bonds,
Eurodollar bonds and bonds  denominated in foreign  currencies,  except that not
more  than 10% of its total  assets  may be  invested  in bonds  denominated  in
foreign  currencies.  Yankee bonds are U.S.  dollar  denominated  obligations of
foreign  issuers that are held in the United States,  and  Eurodollar  bonds are
U.S. dollar denominated  obligations of issuers that are held outside the United
States, primarily in Europe.

         Strategic Fixed Income Portfolio may invest up to 15% of its net assets
in illiquid  securities.  The fund may purchase  securities on a when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total assets. The fund may borrow money from banks or through reverse repurchase
agreements for temporary or emergency purposes,  but not in excess of 33 1/3% of
its total  assets.  The fund may invest in the  securities  of other  investment
companies and may sell short "against the box."

         STRATEGIC INCOME PORTFOLIO'S primary investment objective is to achieve
a high level of current income. As a secondary  investment  objective,  the fund
seeks capital  appreciation.  The fund  strategically  allocates its investments
among three distinct bond market categories:  (1) U.S. government and investment
grade corporate bonds, including mortgage- and asset-backed securities; (2) U.S.
high yield corporate bonds,  including  convertible  bonds, and preferred stock;
and (3)  foreign  and  emerging  market  bonds.  A portion of the fund's  assets
normally is invested in each of these investment sectors.  However, the fund has
the  flexibility  at  any  time  to  invest  all  or  substantially  all  of its
investments in any one sector.

         Strategic  Income  Portfolio  may invest in high  yield  bonds that are
rated as low as D by S&P or C by Moody's.

         The  foreign  and  emerging  market  bonds  in which  Strategic  Income
Portfolio may invest include (1)  government  bonds,  including  Brady bonds and
other sovereign debt, and bonds issued by  multi-national  institutions  such as
the International  Bank for Reconstruction and Development and the International
Monetary  Fund;  (2)  corporate  bonds and  preferred  stock  issued by entities
located  in  foreign  countries,   or  denominated  in  or  indexed  to  foreign
currencies;  (3) interests in foreign loan  participations and assignments;  and
(4) foreign mortgage-backed securities and other structured foreign investments.
The fund may  invest  without  limit in  securities  of  issuers  located in any
country  in  the  world,  including  both  industrialized  and  emerging  market
countries.  The fund  generally is not  restricted  in the portion of its assets
that may be  invested  in a single  country  or region,  but the  fund's  assets
normally are invested in issuers  located in at least three  countries.  No more
than 25% of the  fund's  total  assets  are  invested  in  securities  issued or
guaranteed by any single foreign government.  The fund may invest in foreign and
emerging  market bonds that do not meet any minimum  credit  rating  standard or
that are unrated.

         Mitchell Hutchins believes that Strategic Income  Portfolio's  strategy
of sector  allocation  should be less risky than investing in only one sector of
the bond market. Data from the Lehman Brothers Aggregate Bond Index, the Salomon
Smith Barney High Yield Master Index, the Merrill Lynch High Yield Index and the
Salomon Smith Barney World Government Bond Index indicate that these sectors are
not closely  correlated.  If successful,  the fund's  strategy should enable the
fund to achieve a higher level of  investment  return than if the fund  invested
exclusively in any one investment  sector or allocated a fixed proportion of its
assets to each investment sector.

         Strategic  Income Portfolio may invest up to 10% of its total assets in
preferred  stock  of U.S.  and  foreign  issuers.  It also  may  acquire  equity
securities  when  attached to bonds or as part of a unit  including  bonds or in
connection  with a  conversion  or exchange  of bonds.  The fund also may invest
without  limit  in   certificates   of  deposit  issued  by  banks  and  savings
associations and in bankers' acceptances.


                                       4

         Strategic  Income  Portfolio  may invest in zero  coupon  bonds,  other
original issue  discount  securities,  payment-in-kind  securities and principal
only mortgage-backed  securities. The fund also may invest in fixed and floating
rate loans through either  participations  in or assignments of all or a portion
of loans made by banks.

         Strategic  Income  Portfolio  may invest up to 15% of its net assets in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may  engage in  dollar  rolls  and  reverse  repurchase
agreements  for investment  purposes to enhance the fund's return.  Dollar rolls
and reverse repurchase agreements are considered  borrowings.  The fund may also
borrow from banks or through  reverse  repurchase  agreements  for  temporary or
emergency purposes, but the fund's aggregate borrowings for all purposes may not
exceed 33 1/3% of its total  assets,  plus an  additional 5% of its total assets
for temporary or emergency  purposes.  The fund may invest in the  securities of
other investment companies and may sell short "against the box."

         GLOBAL INCOME PORTFOLIO'S primary investment  objective is high current
income  consistent  with prudent  investment  risk;  capital  appreciation  is a
secondary  objective.  The fund invests principally in high-quality bonds issued
or guaranteed by foreign  governments,  the U.S.  government,  their  respective
agencies or instrumentalities  or supranational  organizations or issued by U.S.
or foreign companies.

         Global Income  Portfolio's  portfolio consists primarily of bonds rated
within one of the two highest grades assigned by S&P,  Moody's or another rating
agency or, if  unrated,  determined  by Mitchell  Hutchins  to be of  comparable
quality.  Normally,  at least 65% of the fund's  total  assets  consist of these
high-quality  bonds (and receivables from the sale of such bonds) denominated in
foreign  currencies or U.S.  dollars of issuers located in at least three of the
following countries:  Australia,  Austria,  Belgium,  Canada, Denmark,  Finland,
France, Germany, Hong Kong, Ireland, Italy, Japan, the Netherlands, New Zealand,
Norway, Portugal,  Singapore, Spain, Sweden, Switzerland, the United Kingdom and
the United  States.  No more than 40% of the fund's  total  assets are  normally
invested in  securities  of issuers  located in any one  country  other than the
United States.  The fund's  investments  may include zero coupon  securities and
other bonds sold with a  discount.  Up to 5% of the fund's  total  assets may be
invested in bonds convertible into equity securities.

         Global  Income  Portfolio  may invest up to 35% of its total  assets in
bonds rated below the two highest grades assigned by a rating agency.  Except as
noted below,  these securities must be investment grade (that is, rated at least
BBB by S&P, Baa by Moody's or comparably  rated by another  rating agency or, if
unrated,  determined by Mitchell Hutchins to be of comparable  quality).  Within
this 35% limitation,  the fund may invest up to 20% of its total assets in bonds
that are rated below investment  grade.  These bonds may be rated as low as D by
S&P, C by Moody's or comparably  rated by another  rating agency or, in the case
of bonds  assigned a short-term  debt rating,  as low as D by S&P or  comparably
rated by another  rating  agency  or, if not so rated,  determined  by  Mitchell
Hutchins  to be of  comparable  quality.  Bonds  rated D by S&P  are in  payment
default or the rating is assigned  upon the filing of a  bankruptcy  petition or
the taking of a similar  action if payments on an  obligation  are  jeopardized.
Bonds  rated C by Moody's  are in the lowest  rated class and can be regarded as
having  extremely  poor  prospects of attaining  any real  investment  standing.
Mitchell  Hutchins  will  purchase  these  securities  for the fund only when it
concludes that the  anticipated  return to the fund on the  investment  warrants
exposure to the additional level of risk.  Lower-rated bonds are often issued by
businesses and governments in emerging markets. Because the fund may also invest
in emerging market bonds that are investment  grade, the fund's total investment
in emerging market bonds may exceed 20% of its total assets.

         Global  Income  Portfolio  may invest up to 35% of its total  assets in
mortgage-backed  securities of U.S. or foreign  issuers that are rated in one of
the two highest rating  categories by S&P,  Moody's or another rating agency or,
if unrated,  determined by Mitchell Hutchins to be of comparable  quality. Up to
20% of the  fund's  total  assets may be  invested  in bonds that are not paying
current  income (a category  that does not include  zero coupon  bonds and other
bonds sold with a  discount).  The fund may  purchase  these  bonds if  Mitchell
Hutchins believes that they have a potential for capital appreciation.  The fund
also may invest in secured and  unsecured  fixed or  floating  rate loans in the
form of participations and assignments.

         Global  Income Fund may invest up to 35% of its total assets in cash or
investment  grade money market  instruments  as part of its ordinary  investment


                                       5
<PAGE>

activities.  The fund's investment of cash collateral from securities lending in
these money market instruments is not subject to this 35% limitation,  and there
is no limitation on its investments in short-term  bonds  denominated in foreign
currencies.

         Global  Income  Portfolio  may  invest  up to 10% of its net  assets in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total assets. The fund may borrow money from banks or through reverse repurchase
agreements for temporary or emergency purposes,  but not in excess of 10% of its
total  assets.  The fund  may  invest  in the  securities  of  other  investment
companies and may sell short "against the box."

         HIGH INCOME PORTFOLIO'S investment objective is to provide high income.
The fund  normally  invests  at least  65% of its  total  assets  in high  yield
corporate  bonds that, at the time of purchase,  are rated B or better by S&P or
Moody's,  are  comparably  rated by another  rating  agency or, if unrated,  are
considered  to be of  comparable  quality  by  Mitchell  Hutchins.  The fund may
include in this 65% of its total assets any equity securities  (including common
stocks and rights and  warrants  for equity  securities)  that are  attached  to
corporate bonds or are part of a unit including  corporate bonds, so long as the
corporate bonds meet these quality requirements.  The fund also may invest up to
35% of its total assets in (1) bonds that are rated below B (and rated as low as
D by S&P or C by Moody's)  or  comparable  unrated  bonds,  (2) U.S.  government
bonds,  (3)  equity  securities  and (4)  money  market  instruments,  including
repurchase agreements.

         Up to 35% of High  Income  Portfolio's  net assets may be  invested  in
securities  of  foreign  issuers,  including  securities  that are  U.S.  dollar
denominated  but  whose  value is linked  to the  value of  foreign  currencies.
However, no more than 10% of the fund's net assets may be invested in securities
of foreign issuers that are denominated and traded in currencies  other than the
U.S. dollar.

         Up to 25% of High Income  Portfolio's  total  assets may be invested in
bonds and equity  securities  that are not paying current  income.  The fund may
purchase these  securities if Mitchell  Hutchins  believes they have a potential
for capital appreciation. High Income Portfolio may invest in zero coupon bonds,
other original  discount  securities,  payment-in-kind  securities and principal
only  mortgage-backed  securities,  all of which are considered income producing
securities.  The fund also may  invest  up to 5% of its net  assets in fixed and
floating rate loans through either  participations in or assignments of all or a
portion of loans made by banks.

         High  Income  Portfolio  may  invest  up to 15% of its  net  assets  in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total assets. The fund may borrow money from banks or through reverse repurchase
agreements for temporary or emergency purposes,  but not in excess of 33 1/3% of
its total  assets.  The fund may invest in the  securities  of other  investment
companies and may sell short "against the box."

         BALANCED PORTFOLIO'S investment objective is high total return with low
volatility.  The fund invests primarily in a combination of three asset classes:
stocks  (equity  securities),  bonds  (investment  grade  bonds) and cash (money
market instruments) and maintains a fixed income allocation (including bonds and
cash) of at least 25%.

         Balanced  Portfolio  may invest in a broad  range of equity  securities
issued by  companies  believed by Mitchell  Hutchins to have the  potential  for
rapid earnings  growth,  investment  grade bonds,  U.S.  government  securities,
convertible securities and money market instruments. The fund may invest in U.S.
dollar  denominated  securities of foreign issuers that are traded on recognized
U.S. exchanges or in the U.S.  over-the-counter market. The fund may also invest
up to 10% of its  assets in bonds and other  securities  (including  convertible
securities) rated below investment grade but rated at least B by S&P or Moody's,
comparably rated by another rating agency or, if unrated, determined by Mitchell
Hutchins to be of comparable  quality.  The fund's bond  investments may include
zero coupon bonds and other original issue discount securities.

         The money market  instruments  in which  Balanced  Portfolio may invest
include U.S.  Treasury  bills and other  obligations  issued or guaranteed as to
interest   and   principal   by  the   U.S.   government,   its   agencies   and
instrumentalities;  obligations of U.S. banks (including certificates of deposit

                                       6
<PAGE>

and bankers'  acceptances) having total assets at the time of purchase in excess
of $1.5 billion;  commercial paper and other short-term  corporate  obligations;
variable and floating rate securities and repurchase  agreements;  participation
interests  in  these  money  market  instruments;  and the  securities  of other
investment  companies that invest exclusively in money market  instruments.  The
fund may also hold cash.

         The  commercial  paper  and  other  short-term  corporate   obligations
purchased  by  Balanced  Portfolio  will  consist  only of  obligations  of U.S.
corporations  that are (1) rated at least  Prime-2 by Moody's or A-2 by S&P, (2)
comparably  rated by another  rating  agency or (3)  unrated and  determined  by
Mitchell  Hutchins to be of comparable  quality.  These  obligations may include
variable amount master demand notes, which are unsecured obligations  redeemable
upon notice that permit  investment of  fluctuating  amounts at varying rates of
interest pursuant to direct arrangements with the issuer of the instrument. Such
obligations are usually unrated by a rating agency.

         Balanced  Portfolio  may invest up to 10% of its net assets in illiquid
securities.  The  fund may  purchase  securities  on a  when-issued  or  delayed
delivery  basis.  The  fund  may  lend its  portfolio  securities  to  qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may borrow  from banks or  through  reverse  repurchase
agreements for temporary or emergency purposes,  but not in excess of 10% of its
total  assets.  The fund  may  invest  in the  securities  of  other  investment
companies and may sell short "against the box."

         GROWTH AND INCOME  PORTFOLIO'S  investment  objective is current income
and capital growth.  The fund seeks to achieve the capital growth portion of its
objective by investing,  under normal  circumstances,  at least 65% of its total
assets in equity securities  believed by Mitchell Hutchins to have the potential
for rapid earnings  growth.  The fund seeks to achieve the income portion of its
investment objective by investing,  under normal circumstances,  at least 65% of
its total  assets in income  producing  securities,  which may include  dividend
paying  equity  securities,  bonds and money  market  instruments.  The fund may
invest  up to 10% of its total  assets in  convertible  securities  rated  below
investment  grade but no lower  than B by S&P or  Moody's,  comparably  rated by
another rating agency or, if unrated,  determined by Mitchell  Hutchins to be of
comparable  quality.  The fund may invest up to 25% of its total  assets in U.S.
dollar  denominated  equity  securities  and bonds of foreign  issuers  that are
traded on recognized U.S. exchanges or in the U.S. over-the-counter market.

         Growth and Income  Portfolio  may invest up to 10% of its net assets in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may borrow  from banks or  through  reverse  repurchase
agreements for temporary or emergency purposes,  but not in excess of 10% of its
total  assets.  The fund  may  invest  in the  securities  of  other  investment
companies and may sell short "against the box."

         TACTICAL ALLOCATION  PORTFOLIO'S  investment objective is total return,
consisting of long-term capital  appreciation and current income. The fund seeks
to achieve its objective by using the Tactical  Allocation  Model,  a systematic
investment  strategy that  allocates its  investments  between an equity portion
designed to track the  performance of the Standard & Poor's 500 Composite  Stock
Index  ("S&P 500 Index")  and a fixed  income  portion  that  generally  will be
comprised of either five-year U.S. Treasury notes or 30-day U.S. Treasury bills.

         Tactical Allocation  Portfolio seeks to achieve total return during all
economic and financial market cycles, with lower volatility than that of the S&P
500 Index.  Mitchell Hutchins  allocates the fund's assets based on the Tactical
Allocation Model's quantitative  assessment of the projected rates of return for
each asset class. The fund seeks to achieve total return during all economic and
financial  market cycles,  with lower volatility than that of the S&P 500 Index.
Mitchell Hutchins allocates the fund's assets based on the Model's  quantitative
assessment  of the  projected  rates of return for each asset  class.  The Model
attempts  to track the S&P 500 Index in  periods  of  strongly  positive  market
performance but attempts to take a more defensive posture by reallocating assets
to bonds or cash  when the Model  signals a  potential  bear  market,  prolonged
downtown in stock prices or significant loss in value.

         The basic premise of the Tactical  Allocation  Model is that  investors
accept the risk of owning stocks, measured as volatility of return, because they
expect a return  advantage.  This expected return  advantage of owning stocks is
called the equity risk premium  ("ERP").  The Model  projects the stock market's

                                       7
<PAGE>

expected ERP based on several factors, including the current price of stocks and
their expected future dividends and the  yield-to-maturity  of the one-year U.S.
Treasury  bill.  When the stock market's ERP is high, the Model signals the fund
to invest  100% in stocks.  Conversely,  when the ERP  decreases  below  certain
threshold  levels,  the Model signals the fund to reduce its exposure to stocks.
The Model can recommend stock allocations of 100%, 75%, 50%, 25% or 0%.

         If the Tactical  Allocation Model recommends a stock allocation of less
than 100%, the Model also recommends a fixed income allocation for the remainder
of the fund's assets.  The Model will  recommend  either bonds  (five-year  U.S.
Treasury notes) or cash (30-day U.S. Treasury bills), but not both. To make this
determination,  the Model  calculates the risk premium  available for the notes.
This bond risk premium ("BRP") is calculated based on the  yield-to-maturity  of
the five-year U.S. Treasury note and the one-year U.S. Treasury bill.

         Tactical Allocation  Portfolio deviates from the recommendations of the
Tactical Allocation Model only to the extent necessary to

      o   Maintain  an amount in cash,  not  expected  to exceed 2% of its total
          assets under normal market conditions, to pay fund operating expenses,
          dividends  and  other   distributions   on  its  shares  and  to  meet
          anticipated redemptions of shares and

      o   Satisfy  the  diversification  requirements  imposed  by the  Internal
          Revenue  Code on  segregated  asset  accounts  used  to fund  variable
          annuity and variable life insurance contracts.  These  diversification
          requirements  must be satisfied by the fund as an  investment  vehicle
          underlying   the   segregated   asset   accounts.   To  satisfy  these
          requirements,  the  fund may not  invest  more  than 55% of its  total
          assets in U.S. Treasury obligations.  If the Tactical Allocation Model
          recommends  more  than a 50%  allocation  to bonds  or cash,  Tactical
          Allocation  Portfolio  must invest a portion of its assets in bonds or
          money market instruments that are not U.S. Treasury obligations.

         In  its  stock  portion,  Tactical  Allocation  Portfolio  attempts  to
duplicate, before the deduction of operating expenses, the investment results of
the S&P 500 Index.  Securities in the S&P 500 Index are selected, and may change
from  time to time,  based on a  statistical  analysis  of such  factors  as the
issuer's   market   capitalization   (the  S&P  500   Index   emphasizes   large
capitalization  stocks),  the security's  trading activity and its adequacy as a
representative of stocks in a particular  industry sector. The fund's investment
results  for its stock  portion  will not be  identical  to those of the S&P 500
Index.  Deviations  from the  performance  of the S&P 500 Index may result  from
purchases and  redemptions of fund shares that may occur daily,  as well as from
expenses borne by the fund. Instead,  the fund attempts to achieve a correlation
of at least 0.95 between the performance of the fund's stock portion, before the
deduction of operating expenses, and that of the S&P 500 Index (a correlation of
1.00  would  mean that the net asset  value of the stock  portion  increased  or
decreased in exactly the same  proportion as changes in the S&P 500 Index).  The
S&P 500 Index can include U.S. dollar  denominated  equity securities of foreign
issuers,  and the fund invests in those securities to the extent needed to track
the performance of the S&P 500 Index.

         Asset reallocations are made, if required, on the first business day of
each month.  In addition to any  reallocation of assets directed by the Tactical
Allocation Model, any material amounts resulting from appreciation or receipt of
dividends,  other distributions,  interest payments and proceeds from securities
maturing in each of the asset classes are reallocated (or  "rebalanced")  to the
extent  practicable  to establish  the Model's  recommended  asset mix. Any cash
maintained to pay fund operating expenses, pay dividends and other distributions
and to meet share redemptions is invested on a daily basis.

         Tactical Allocation Portfolio may invest up to 15% of its net assets in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may borrow  from banks or  through  reverse  repurchase
agreements for temporary or emergency purposes,  but not in excess of 33 1/3% of
its total  assets.  The fund may invest in the  securities  of other  investment
companies and may sell short "against the box."

         GROWTH   PORTFOLIO'S   investment   objective  is   long-term   capital
appreciation.  The  fund  invests  primarily  in  equity  securities  issued  by

                                       8
<PAGE>

companies  believed  by  Mitchell  Hutchins to have  substantial  potential  for
capital growth. Under normal circumstances, the fund invests at least 65% of its
total assets in equity securities.

         Growth  Portfolio  may  invest  up to 35% of its  total  assets in U.S.
government  bonds and in corporate  bonds,  including  up to 10% in  convertible
bonds that are rated below  investment  grade.  These  convertible  bonds may be
rated no lower than B by S&P or  Moody's,  comparably  rated by  another  rating
agency or, if  unrated,  determined  by Mitchell  Hutchins  to be of  comparable
quality.  The fund may  invest  up to 25% of its  total  assets  in U.S.  dollar
denominated  equity  securities and bonds of foreign  issuers that are traded on
recognized U.S. exchanges or in the U.S. over-the-counter market.

         Growth  Portfolio  may invest up to 10% of its net  assets in  illiquid
securities.  The  fund may  purchase  securities  on a  when-issued  or  delayed
delivery  basis.  The  fund  may  lend its  portfolio  securities  to  qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may borrow  from banks or  through  reverse  repurchase
agreements for temporary or emergency purposes,  but not in excess of 10% of its
total  assets.  The fund  may  invest  in the  securities  of  other  investment
companies and may sell short "against the box."

         AGGRESSIVE  GROWTH  PORTFOLIO'S   investment  objective  is  maximizing
long-term  capital  appreciation.  The  fund's  investments  are  managed  by  a
sub-adviser,   Nicholas-Applegate   Capital  Management.   Under  normal  market
conditions,  the fund invests at least 75% of its total assets in common stocks.
The fund invests  primarily in common  stocks of U.S.  companies  the assets and
stock  prices of which the  sub-adviser  expects to grow faster than the average
rate  of  companies  in the  S&P  500  Index.  The  fund  is not  restricted  to
investments in companies of any  particular  size. The fund may invest up to 25%
of its total assets in preferred and  convertible  securities  issued by similar
growth  companies,  U.S.  government bonds and investment grade corporate bonds.
The fund may  invest up to 25% of its total  assets in U.S.  dollar  denominated
equity  securities  and bonds of foreign  issuers that are traded on  recognized
U.S. exchanges or in the U.S. over-the-counter market.

         Aggressive  Growth  Portfolio may invest up to 15% of its net assets in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed delivery basis. The fund may lend its portfolio  securities to qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may borrow  from banks or  through  reverse  repurchase
agreements for temporary or emergency purposes,  but not in excess of 20% of its
total  assets.  The fund  may  invest  in the  securities  of  other  investment
companies and may sell short "against the box."

         SMALL  CAP  PORTFOLIO'S   investment  objective  is  long-term  capital
appreciation.  The fund  invests  at least  65% of its  total  assets  in equity
securities of small capitalization ("small cap") companies, which are defined as
companies  having  market  capitalizations  of up to $1.5 billion at the time of
purchase. The fund may invest up to 35% of its total assets in equity securities
of companies that are larger than small cap  companies,  as well as in bonds and
money market instruments.  This includes up to 10% in convertible bonds that are
rated below investment  grade but no lower than B by S&P or Moody's,  comparably
rated by another rating agency or, if unrated,  determined by Mitchell  Hutchins
to be of comparable  quality.  The fund may invest up to 25% of its total assets
in U.S. dollar  denominated equity securities of foreign issuers that are traded
on recognized U.S. exchanges or in the U.S. over-the-counter market.

         Small Cap  Portfolio may invest up to 15% of its net assets in illiquid
securities.  The  fund may  purchase  securities  on a  when-issued  or  delayed
delivery  basis.  The  fund  may  lend its  portfolio  securities  to  qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
total  assets.  The fund may borrow  from banks or  through  reverse  repurchase
agreements for temporary or emergency purposes,  but not in excess of 33 1/3% of
its total  assets.  The fund may invest in the  securities  of other  investment
companies and may sell short "against the box."

         GLOBAL EQUITY  PORTFOLIO'S  investment  objective is long-term  capital
appreciation. The fund invests primarily in common stocks issued by companies in
United States,  Europe, Japan and the Pacific Basin. Under normal circumstances,
the fund  invests  at  least  65% of its  total  assets  in  common  stocks  and
securities convertible into common stocks. The fund may also hold other types of
securities,  including non-convertible  investment grade bonds, government bonds
and money  market  securities  of U.S.  and foreign  issuers  and cash  (foreign
currencies or U.S. dollars).

         Mitchell Hutchins  allocates Global Equity  Portfolio's  assets between
U.S.  investments and foreign  investments  and manages the assets  allocated to

                                       9
<PAGE>

U.S. investments. Mitchell Hutchins has selected Invista Capital Management, LLC
("Invista") to serve as the fund's sub-adviser to manage the assets allocated to
the fund's foreign investments.  Mitchell Hutchins reevaluates the allocation of
the fund's  assets  between  U.S.  and foreign  securities  monthly and does not
expect to reallocate the fund's assets to reflect relatively minor changes (that
is, less than 5%) in the asset allocation model employed. When Mitchell Hutchins
determines that a reallocation of the fund's assets is appropriate, the fund may
effect the reallocation by using cash available from the purchase of fund shares
or by  selectively  selling  securities  in a region  to meet  share  redemption
requests in addition to buying or selling portfolio  securities  specifically to
implement a reallocation. The fund also may use derivative instruments to adjust
its exposure to U.S. and foreign stock markets. Mitchell Hutchins determines the
extent to which the fund uses  derivative  instruments  for this  purpose and is
responsible for implementing these transactions.

         Under normal  circumstances,  Global Equity Portfolio  invests at least
80% of its total  assets in  securities  of  issuers  in the  United  States and
countries  represented  in the Morgan  Stanley  Capital  International  ("MSCI")
Europe,  Australasia and Far East Index ("EAFE Index"). The EAFE Index is a well
known index that reflects most major equity  markets  outside the United States.
The fund may invest up to 20% of its assets in securities of issuers  located in
other countries (for example,  Canada and emerging  markets.)  Mitchell Hutchins
may also invest, as part of the fund's U.S. investments, up to 10% of the fund's
total assets in U.S. dollar  denominated  equity securities and bonds of foreign
issuers  that  are  traded  on  recognized   U.S.   exchanges  or  in  the  U.S.
over-the-counter market.

         Global  Equity  Portfolio  may  invest  up to 10% of its net  assets in
illiquid  securities.  The fund may  purchase  securities  on a  when-issued  or
delayed  delivery  basis,  but these  securities  may not  exceed 10% of its net
assets. The fund may lend its portfolio  securities to qualified  broker-dealers
or institutional  investors in an amount up to 33 1/3% of its total assets.  The
fund may borrow money from banks or through  reverse  repurchase  agreements for
temporary or emergency  purposes,  but not in excess of 10% of its total assets.
The fund may invest in the securities of other investment companies and may sell
short "against the box."

              THE FUNDS' INVESTMENTS, RELATED RISKS AND LIMITATIONS

         The following  supplements the information  contained in the Prospectus
and above  concerning  the funds'  investments,  related risks and  limitations.
Except as  otherwise  indicated  in the  Prospectus  or the SAI,  the funds have
established  no policy  limitations  on their ability to use the  investments or
techniques discussed in these documents.

         EQUITY  SECURITIES.  Equity  securities  include  common  stocks,  most
preferred stocks and securities that are convertible into them, including common
stock purchase  warrants and rights,  equity interests in trusts,  partnerships,
joint ventures or similar  enterprises and depositary  receipts.  Common stocks,
the  most  familiar  type,   represent  an  equity  (ownership)  interest  in  a
corporation.

         Preferred  stock has certain fixed income  features,  like a bond,  but
actually it is equity that is senior to a company's  common  stock.  Convertible
bonds may be converted into or exchanged for a prescribed amount of common stock
of the same or a  different  issuer  within  a  particular  period  of time at a
specified  price or formula.  Some preferred stock also may be converted into or
exchanged for common stock. Depositary receipts typically are issued by banks or
trust companies and evidence ownership of underlying equity securities.

         While  past  performance  does not  guarantee  future  results,  equity
securities historically have provided the greatest long-term growth potential in
a company.  However, their prices generally fluctuate more than other securities
and reflect changes in a company's financial condition and in overall market and
economic  conditions.  Common stocks generally represent the riskiest investment
in a  company.  It is  possible  that a fund may  experience  a  substantial  or
complete loss on an individual  equity  investment.  While this is possible with
bonds, it is less likely.

         BONDS are fixed or variable  rate debt  obligations,  including  bills,
notes,  debentures,   money  market  instruments  and  similar  instruments  and
securities.  Mortgage-  and  asset-backed  securities  are types of  bonds,  and
certain  types of income  producing,  non-convertible  preferred  stocks  may be
treated  as  bonds  for  investment  purposes.   Bonds  generally  are  used  by
corporations,  governments and other issuers to borrow money from investors. The
issuer pays the investor a fixed or variable  rate of interest and normally must
repay the amount borrowed on or before maturity.  Many preferred stocks and some
bonds are "perpetual" in that they have no maturity date.

                                       10
<PAGE>

         Bonds are subject to interest rate risk and credit risk.  Interest rate
risk is the risk that  interest  rates  will rise and  that,  as a result,  bond
prices  will  fall,  lowering  the value of a fund's  investments  in bonds.  In
general,  bonds having  longer  durations  are more  sensitive to interest  rate
changes than are bonds with shorter  durations.  Credit risk is the risk that an
issuer may be unable or unwilling to pay interest and/or  principal on the bond.
Credit risk can be affected by many factors,  including  adverse  changes in the
issuer's own financial condition or in economic conditions.

         CREDIT  RATINGS;  NON-INVESTMENT  GRADE BONDS.  Moody's,  S&P and other
rating agencies are private  services that provide ratings of the credit quality
of bonds and certain other securities.  A description of the ratings assigned to
corporate  bonds by Moody's and S&P is included in the Appendix to this SAI. The
process  by  which  Moody's  and  S&P  determine  ratings  for   mortgage-backed
securities  includes  consideration of the likelihood of the receipt by security
holders of all  distributions,  the nature of the underlying  assets, the credit
quality of the  guarantor,  if any,  and the  structural,  legal and tax aspects
associated with these securities. Not even the highest such rating represents an
assessment of the likelihood that principal prepayments will be made by obligors
on the underlying assets or the degree to which such prepayments may differ from
that originally  anticipated,  nor do such ratings address the possibility  that
investors may suffer a lower than  anticipated  yield or that  investors in such
securities may fail to recoup fully their initial investment due to prepayments.

         Credit ratings attempt to evaluate the safety of principal and interest
payments,  but they do not  evaluate  the  volatility  of a bond's  value or its
liquidity and do not guarantee the  performance of the issuer.  Rating  agencies
may fail to make timely  changes in credit  ratings in  response  to  subsequent
events, so that an issuer's current  financial  condition may be better or worse
than the rating  indicates.  There is a risk that rating  agencies may downgrade
the rating of a bond. Subsequent to a bond's purchase by a fund, it may cease to
be rated or its rating may be reduced  below the  minimum  rating  required  for
purchase by the fund. The funds may use these ratings in determining  whether to
purchase,  sell or hold a  security.  It should  be  emphasized,  however,  that
ratings are general and are not  absolute  standards  of quality.  Consequently,
bonds with the same maturity, interest rate and rating may have different market
prices.

         In addition to ratings  assigned to  individual  bond issues,  Mitchell
Hutchins or the  applicable  sub-adviser  will analyze  interest rate trends and
developments  that may affect  individual  issuers,  including  factors  such as
liquidity, profitability and asset quality. The yields on bonds are dependent on
a variety  of  factors,  including  general  money  market  conditions,  general
conditions in the bond market,  the financial  condition of the issuer, the size
of the offering,  the maturity of the obligation and its rating. There is a wide
variation in the quality of bonds, both within a particular  classification  and
between classifications.  An issuer's obligations under its bonds are subject to
the provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of bond holders or other  creditors of an issuer;  litigation  or other
conditions  may also  adversely  affect  the power or ability of issuers to meet
their obligations for the payment of interest and principal on their bonds.

         Investment  grade  bonds  are rated in one of the four  highest  rating
categories by Moody's or S&P,  comparably  rated by another rating agency or, if
unrated,  determined by Mitchell Hutchins or the applicable sub-adviser to be of
comparable  quality.  Moody's  considers bonds rated Baa (its lowest  investment
grade rating) to have  speculative  characteristics.  This means that changes in
economic conditions or other circumstances are more likely to lead to a weakened
capacity to make  principal  and interest  payments  than is the case for higher
rated  bonds.  Bonds  rated D by S&P are in payment  default  or such  rating is
assigned  upon the filing of a  bankruptcy  petition  or the taking of a similar
action if payments on an obligation  are  jeopardized.  Bonds rated C by Moody's
are in the lowest  rated  class and can be  regarded  as having  extremely  poor
prospects of attaining any real investment standing.

         Non-investment   grade  bonds  (commonly  known  as  "junk  bonds"  and
sometimes  referred to as "high-yield"  bonds) are rated Ba or lower by Moody's,
BB or lower by S&P,  comparably  rated by another  rating agency or, if unrated,
determined by Mitchell Hutchins or the sub-adviser to be of comparable  quality.
A fund's investments in non-investment  grade bonds entail greater risk than its
investments  in higher rated bonds.  Non-investment  grade bonds are  considered
predominantly  speculative  with respect to the issuer's ability to pay interest
and repay  principal  and may  involve  significant  risk  exposure  to  adverse
conditions.  Non-investment  grade bonds  generally offer a higher current yield
than that available for investment grade issues;  however,  they involve greater
risks,  in that they are  especially  sensitive  to  adverse  changes in general
economic  conditions and in the industries in which the issuers are engaged,  to
changes in the financial  condition of the issuers and to price  fluctuations in

                                       11
<PAGE>

response to changes in interest  rates.  During periods of economic  downturn or
rising interest rates, highly leveraged issuers may experience  financial stress
that could  adversely  affect  their  ability to make  payments of interest  and
principal and increase the possibility of default. In addition, such issuers may
not have more  traditional  methods of  financing  available  to them and may be
unable to repay debt at maturity by refinancing. The risk of loss due to default
by such issuers is significantly  greater because such securities frequently are
unsecured by  collateral  and will not receive  payment until more senior claims
are paid in full.

         The market for non-investment grade bonds,  especially those of foreign
issuers,  has  expanded  rapidly  in  recent  years,  which has been a period of
generally  expanding  growth  and  lower  inflation.  These  securities  will be
susceptible  to greater  risk when  economic  growth  slows or reverses and when
inflation increases or deflation occurs. This has been reflected in recent years
by volatility in emerging market securities. In the past, many lower rated bonds
experienced  substantial  price  declines  reflecting an  expectation  that many
issuers of such securities might experience financial difficulties. As a result,
the yields on lower rated bonds rose dramatically.  However, those higher yields
did not reflect the value of the income  stream that holders of such  securities
expected.  Rather, they reflected the risk that holders of such securities could
lose a  substantial  portion  of  their  value  due to  the  issuers'  financial
restructurings or defaults by the issuers.  There can be no assurance that those
declines will not recur.

         The market for non-investment grade bonds generally is thinner and less
active than that for higher quality securities, which may limit a fund's ability
to sell such  securities  at fair value in response to changes in the economy or
financial markets.  Adverse publicity and investor  perceptions,  whether or not
based on  fundamental  analysis,  may also  decrease the values and liquidity of
non-investment grade bonds, especially in a thinly traded market.

         U.S.  GOVERNMENT  SECURITIES  include  direct  obligations  of the U.S.
Treasury  (such as Treasury  bills,  notes or bonds) and  obligations  issued or
guaranteed as to principal and interest (but not as to market value) by the U.S.
government,  its agencies or its  instrumentalities.  U.S. government securities
include  mortgage-backed  securities issued or guaranteed by government agencies
or  government-sponsored  enterprises.  Other U.S. government  securities may be
backed  by the full  faith  and  credit  of the  U.S.  government  or  supported
primarily or solely by the creditworthiness of the government-related issuer or,
in the case of mortgage-backed securities, by pools of assets.

         U.S. government securities also include separately traded principal and
interest  components  of securities  issued or guaranteed by the U.S.  Treasury,
which are traded independently under the Separate Trading of Registered Interest
and Principal of Securities ("STRIPS") program.  Under the STRIPS programs,  the
principal  and interest  components  are  individually  numbered and  separately
issued by the U.S. Treasury.

         Treasury  inflation  protected   securities  ("TIPS")  (also  known  as
"inflation-indexed  securities") are Treasury bonds on which the principal value
is adjusted  daily in  accordance  with  changes in the  Consumer  Price  Index.
Interest on TIPS is payable  semi-annually on the adjusted  principal value. The
principal  value of TIPS would  decline  during  periods of  deflation,  but the
principal  amount  payable at maturity  would not be less than the  original par
amount.  If inflation is lower than expected  while a fund holds TIPS,  the fund
may earn  less on the TIPS than it would on  conventional  Treasury  bonds.  Any
increase  in the  principal  value of TIPS is taxable  in the year the  increase
occurs,  even though  holders do not receive cash  representing  the increase at
that time. See "Taxes -- Other Information," below.

         ASSET-BACKED   SECURITIES.   Asset-backed  securities  have  structural
characteristics  similar to  mortgage-backed  securities,  as  discussed in more
detail below.  However,  the underlying assets are not first lien mortgage loans
or interests therein, but include assets such as motor vehicle installment sales
contracts,  other  installment  sales  contracts,  home equity loans,  leases of
various  types of real and personal  property  and  receivables  from  revolving
credit (credit card) agreements.  Such assets are securitized through the use of
trusts or special purpose  corporations.  Payments or distributions of principal
and interest  may be  guaranteed  up to a certain  amount and for a certain time
period  by a letter of credit or pool  insurance  policy  issued by a  financial
institution  unaffiliated with the issuer,  or other credit  enhancements may be
present.

         MORTGAGE-BACKED SECURITIES. Mortgage-backed securities represent direct
or indirect interests in pools of underlying  mortgage loans that are secured by
real  property.  U.S.  government   mortgage-backed  securities  are  issued  or
guaranteed  as to the payment of principal  and  interest  (but not as to market

                                       12
<PAGE>

value)  by  Ginnie  Mae  (also  known  as  the  Government   National   Mortgage
Association),   Fannie  Mae  (also  known  as  the  Federal  National   Mortgage
Association),  Freddie  Mac  (also  known  as the  Federal  Home  Loan  Mortgage
Corporation)  or  other  government   sponsored   enterprises.   Other  domestic
mortgage-backed   securities  are  sponsored  or  issued  by  private  entities,
generally  originators  of and investors in mortgage  loans,  including  savings
associations, mortgage bankers, commercial banks, investment bankers and special
purposes  entities  (collectively,  "Private  Mortgage  Lenders").  Payments  of
principal   and   interest   (but  not  the  market   value)  of  such   private
mortgage-backed  securities may be supported by pools of mortgage loans or other
mortgage-backed  securities that are guaranteed,  directly or indirectly, by the
U.S.  government  or one of its  agencies or  instrumentalities,  or they may be
issued without any government  guarantee of the underlying  mortgage  assets but
with some form of non-government  credit  enhancement.  Foreign  mortgage-backed
securities  may be issued by mortgage  banks and other  private or  governmental
entities  outside the United  States and are  supported  by interests in foreign
real estate.

         Mortgage-backed  securities  may be composed of one or more classes and
may be  structured  either as  pass-through  securities or  collateralized  debt
obligations. Multiple-class mortgage-backed securities are referred to herein as
"CMOs."  Some  CMOs are  directly  supported  by other  CMOs,  which in turn are
supported by mortgage pools.  Investors  typically  receive  payments out of the
interest  and  principal  on the  underlying  mortgages.  The  portions of these
payments  that  investors  receive,  as well as the  priority of their rights to
receive  payments,  are determined by the specific terms of the CMO class.  CMOs
involve special risk and evaluating them requires special knowledge.

         A major difference between  mortgage-backed  securities and traditional
bonds is that interest and principal payments are made more frequently  (usually
monthly) and that  principal  may be repaid at any time  because the  underlying
mortgage  loans may be  prepaid  at any time.  When  interest  rates go down and
homeowners refinance their mortgages, mortgage-backed securities may be paid off
more quickly than investors  expect.  When interest rates rise,  mortgage-backed
securities may be paid off more slowly than originally expected.  Changes in the
rate or  "speed"  of these  prepayments  can cause the value of  mortgage-backed
securities to fluctuate rapidly.

         Mortgage-backed  securities  also may  decrease in value as a result of
increases in interest rates and,  because of prepayments,  may benefit less than
other bonds from declining  interest  rates.  Reinvestments  of prepayments  may
occur at lower  interest  rates than the  original  investment,  thus  adversely
affecting a fund's yield. Actual prepayment  experience may cause the yield of a
mortgage-backed security to differ from what was assumed when the fund purchased
the  security.  Prepayments  at a slower rate than  expected  may  lengthen  the
effective  life of a  mortgage-backed  security.  The value of  securities  with
longer  effective lives generally  fluctuates more widely in response to changes
in interest rates than the value of securities with shorter effective lives.

         CMO classes may be specially  structured  in a manner that provides any
of a wide  variety  of  investment  characteristics,  such as  yield,  effective
maturity and interest rate sensitivity.  As market conditions  change,  however,
and  particularly  during  periods of rapid or  unanticipated  changes in market
interest  rates,  the  attractiveness  of the CMO classes and the ability of the
structure  to  provide  the  anticipated   investment   characteristics  may  be
significantly  reduced.  These  changes can result in  volatility  in the market
value, and in some instances reduced liquidity, of the CMO class.

         Certain  classes  of CMOs  and  other  mortgage-backed  securities  are
structured  in a manner  that  makes  them  extremely  sensitive  to  changes in
prepayment  rates.  Interest only ("IO") and principal  only ("PO")  classes are
examples of this.  IOs are entitled to receive all or a portion of the interest,
but  none  (or  only a  nominal  amount)  of the  principal  payments,  from the
underlying  mortgage assets.  If the mortgage assets underlying an IO experience
greater  than  anticipated  principal  prepayments,  then the  total  amount  of
interest  payments  allocable  to the IO  class,  and  therefore  the  yield  to
investors,  generally will be reduced.  In some instances,  an investor in an IO
may fail to recoup all of his or her initial investment, even if the security is
government  issued or guaranteed or is rated AAA or the equivalent.  Conversely,
PO classes are entitled to receive all or a portion of the  principal  payments,
but none of the interest,  from the underlying  mortgage assets.  PO classes are
purchased at substantial  discounts from par, and the yield to investors will be
reduced if  principal  payments are slower than  expected.  Some IOs and POs, as
well as other CMO classes,  are structured to have special  protections  against
the effects of prepayments. These structural protections,  however, normally are
effective  only  within  certain  ranges of  prepayment  rates and thus will not
protect investors in all  circumstances.  Inverse floating rate CMO classes also
may be extremely  volatile.  These classes pay interest at a rate that decreases
when a specified index of market rates increases.

         The market for privately issued  mortgage-backed  securities is smaller
and less liquid than the market for U.S. government mortgage-backed  securities.
Foreign  mortgage-backed  securities markets are substantially smaller than U.S.
markets,  but have been  established in several  countries,  including  Germany,
Denmark, Sweden, Canada and Australia,  and may be developed elsewhere.  Foreign
mortgage-backed  securities  generally are structured  differently than domestic
mortgage-backed  securities,  but they normally  present  substantially  similar
investment  risks as well as the other risks  normally  associated  with foreign
securities.

         During 1994, the value and liquidity of many mortgage-backed securities
declined  sharply due primarily to increases in interest rates.  There can be no
assurance  that such  declines  will not  recur.  The  market  value of  certain
mortgage-backed  securities,  including  IO and PO  classes  of  mortgage-backed
securities, can be extremely volatile, and these securities may become illiquid.
Mitchell  Hutchins  or the  applicable  sub-adviser  seeks  to  manage  a fund's
investments  in  mortgage-backed  securities  so  that  the  volatility  of  its
portfolio,  taken as a whole,  is  consistent  with  its  investment  objective.
Management  of  portfolio  duration  is an  important  part  of  this.  However,
computing  the duration of  mortgage-backed  securities  is complex.  See,  "The
Funds'  Investments,  Related  Risks and  Limitations  -- Duration." If Mitchell
Hutchins  or the  applicable  sub-adviser  does  not  compute  the  duration  of
mortgage-backed  securities correctly,  the value of the fund's portfolio may be
either more or less sensitive to changes in market interest rates than intended.
In  addition,  if  market  interest  rates  or other  factors  that  affect  the
volatility of securities held by a fund change in ways that Mitchell Hutchins or
the applicable  sub-adviser does not anticipate,  the fund's ability to meet its
investment objective may be reduced.

         More information  concerning these  mortgage-backed  securities and the
related  risks  of  investments  therein  is  set  forth  below.  New  types  of
mortgage-backed  securities  are  developed  and marketed from time to time and,
consistent  with their  investment  limitations,  the funds  expect to invest in
those new types of  mortgage-backed  securities  that  Mitchell  Hutchins or the
applicable   sub-adviser  believe  may  assist  the  funds  in  achieving  their
investment  objectives.  Similarly,  the  funds may  invest  in  mortgage-backed
securities issued by new or existing  governmental or private issuers other than
those  identified  herein.  The funds that may invest in foreign  securities may
invest  in  foreign   mortgage-backed   securities,   which  may  be  structured
differently than domestic mortgage-backed securities.

         GINNIE MAE  CERTIFICATES  -- Ginnie  Mae  guarantees  certain  mortgage
pass-through certificates ("Ginnie Mae certificates") that are issued by Private
Mortgage Lenders and that represent  ownership  interests in individual pools of
residential  mortgage  loans.  These  securities are designed to provide monthly
payments of interest and principal to the investor.  Timely  payment of interest
and  principal  is backed by the full faith and  credit of the U.S.  government.
Each mortgagor's  monthly payments to his lending institution on his residential
mortgage are "passed through" to certificateholders  such as the funds. Mortgage
pools consist of whole mortgage loans or  participations in loans. The terms and
characteristics of the mortgage  instruments are generally uniform within a pool
but may vary among pools.  Lending institutions that originate mortgages for the
pools are subject to certain standards,  including credit and other underwriting
criteria for individual mortgages included in the pools.

         FANNIE MAE CERTIFICATES -- Fannie Mae facilitates a national  secondary
market in residential  mortgage  loans insured or guaranteed by U.S.  government
agencies  and in  privately  insured or  uninsured  residential  mortgage  loans
(sometimes referred to as "conventional mortgage loans" or "conventional loans")
through its mortgage purchase and  mortgage-backed  securities sales activities.
Fannie Mae issues guaranteed  mortgage  pass-through  certificates  ("Fannie Mae
certificates"),  which  represent  pro rata shares of all interest and principal
payments made and owed on the underlying  pools.  Fannie Mae  guarantees  timely
payment of interest  and  principal on Fannie Mae  certificates.  The Fannie Mae
guarantee is not backed by the full faith and credit of the U.S. government.

         FREDDIE MAC  CERTIFICATES  -- Freddie Mac also  facilitates  a national
secondary  market  for  conventional  residential  and  U.S.  government-insured
mortgage  loans  through its mortgage  purchase and  mortgage-backed  securities
sales  activities.  Freddie  Mac  issues  two  types  of  mortgage  pass-through
securities:  mortgage participation certificates ("PCs") and guaranteed mortgage
certificates  ("GMCs").  Each PC represents a pro rata share of all interest and
principal  payments made and owed on the underlying pool.  Freddie Mac generally
guarantees timely monthly payment of interest on PCs and the ultimate payment of
principal, but it also has a PC program under which it guarantees timely payment
of both  principal  and interest.  GMCs also  represent a pro rata interest in a
pool of mortgages.  These instruments,  however, pay interest  semi-annually and
return  principal once a year in guaranteed  minimum  payments.  The Freddie Mac
guarantee is not backed by the full faith and credit of the U.S. government.

         PRIVATE MORTGAGE-BACKED SECURITIES -- Mortgage-backed securities issued
by  Private  Mortgage  Lenders  are  structured  similarly  to  CMOs  issued  or
guaranteed  by Ginnie Mae,  Fannie Mae and  Freddie  Mac.  Such  mortgage-backed
securities  may be supported by pools of U.S.  government  or agency  insured or
guaranteed  mortgage loans or by other  mortgage-backed  securities  issued by a
government agency or instrumentality,  but they generally are supported by pools
of conventional  (i.e.,  non-government  guaranteed or insured)  mortgage loans.
Since such  mortgage-backed  securities normally are not guaranteed by an entity
having the credit  standing of Ginnie  Mae,  Fannie Mae and  Freddie  Mac,  they
normally are structured with one or more types of credit  enhancement.  See "The
Funds'   Investments,   Related  Risks  and   Limitations  --  Types  of  Credit
Enhancement." These credit enhancements do not protect investors from changes in
market value.

         COLLATERALIZED    MORTGAGE   OBLIGATIONS   AND   MULTI-CLASS   MORTGAGE
PASS-THROUGHS -- CMOs are debt obligations that are  collateralized  by mortgage
loans or mortgage pass-through securities (collectively "Mortgage Assets"). CMOs
may be issued by Private  Mortgage  Lenders or by  government  entities  such as
Fannie Mae or Freddie Mac.  Multi-class  mortgage  pass-through  securities  are
interests in trusts that are comprised of Mortgage Assets and that have multiple
classes  similar  to those in CMOs.  Unless  the  context  indicates  otherwise,
references herein to CMOs include multi-class mortgage pass-through  securities.
Payments of principal of, and interest on, the Mortgage  Assets (and in the case
of CMOs,  any  reinvestment  income  thereon)  provide the funds to pay the debt
service  on the  CMOs  or to make  scheduled  distributions  on the  multi-class
mortgage pass-through securities.

         In a CMO,  a series of bonds or  certificates  is  issued  in  multiple
classes.  Each class of CMO,  also  referred to as a  "tranche,"  is issued at a
specific  fixed or  floating  coupon  rate and has a  stated  maturity  or final
distribution date.  Principal  prepayments on the Mortgage Assets may cause CMOs
to be retired  substantially  earlier  than  their  stated  maturities  or final
distribution  dates.  Interest is paid or accrued on all classes of a CMO (other
than any PO class) on a monthly,  quarterly or semi-annual  basis. The principal
and interest on the Mortgage  Assets may be allocated  among the several classes
of a CMO in many ways. In one  structure,  payments of principal,  including any
principal  prepayments,  on the Mortgage  Assets are applied to the classes of a
CMO in the order of their  respective  stated  maturities or final  distribution
dates so that no payment of principal will be made on any class of the CMO until
all other classes having an earlier stated maturity or final  distribution  date
have been paid in full. In some CMO structures, all or a portion of the interest
attributable  to one or more of the CMO  classes  may be added to the  principal
amounts   attributable   to  such  classes,   rather  than  passed   through  to
certificateholders  on a current basis,  until other classes of the CMO are paid
in full.

         Parallel pay CMOs are  structured  to provide  payments of principal on
each payment date to more than one class. These simultaneous  payments are taken
into account in calculating the stated maturity date or final  distribution date
of each  class,  which,  as with  other CMO  structures,  must be retired by its
stated maturity date or final distribution date but may be retired earlier.

         Some CMO  classes  are  structured  to pay  interest  at rates that are
adjusted  in  accordance  with a formula,  such as a multiple or fraction of the
change in a specified  interest rate index,  so as to pay at a rate that will be
attractive in certain interest rate environments but not in others. For example,
an inverse  floating rate CMO class pays interest at a rate that  increases as a
specified  interest rate index decreases but decreases as that index  increases.
For  other CMO  classes,  the  yield  may move in the same  direction  as market
interest rates -- i.e., the yield may increase as rates increase and decrease as
rates decrease -- but may do so more rapidly or to a greater degree.  The market
value of such  securities  generally is more  volatile than that of a fixed-rate
obligation.  Such  interest  rate  formulas  may  be  combined  with  other  CMO
characteristics.  For example,  a CMO class may be an inverse IO class, on which
the holders are entitled to receive no payments of principal and are entitled to
receive  interest at a rate that will vary inversely with a specified index or a
multiple thereof.

         TYPES OF CREDIT  ENHANCEMENT  -- To lessen  the effect of  failures  by
obligors on Mortgage  Assets to make  payments,  mortgage-backed  securities may
contain elements of credit  enhancement.  Such credit enhancement falls into two
categories:  (1) liquidity  protection and (2) loss protection.  Loss protection
relates to losses resulting after default by an obligor on the underlying assets
and collection of all amounts recoverable  directly from the obligor and through
liquidation of the collateral.  Liquidity  protection refers to the provision of
advances,  generally by the entity administering the pool of assets (usually the
bank,  savings  association or mortgage  banker that  transferred the underlying
loans to the issuer of the security),  to ensure that the receipt of payments on
the underlying pool occurs in a timely fashion. Loss protection ensures ultimate

                                       15
<PAGE>

payment of the obligations on at least a portion of the assets in the pool. Such
protection may be provided through guarantees,  insurance policies or letters of
credit  obtained by the issuer or sponsor,  from third parties,  through various
means  of  structuring   the  transaction  or  through  a  combination  of  such
approaches. A fund will not pay any additional fees for such credit enhancement,
although  the  existence  of  credit  enhancement  may  increase  the price of a
security.  Credit  enhancements do not provide protection against changes in the
market value of the security.  Examples of credit enhancement arising out of the
structure of the transaction include "senior-subordinated  securities" (multiple
class securities with one or more classes subordinate to other classes as to the
payment of principal thereof and interest thereon, with the result that defaults
on the  underlying  assets are borne  first by the  holders of the  subordinated
class),  creation  of  "spread  accounts"  or  "reserve  funds"  (where  cash or
investments,  sometimes  funded from a portion of the payments on the underlying
assets, are held in reserve against future losses) and  "over-collateralization"
(where the  scheduled  payments on, or the principal  amount of, the  underlying
assets  exceed  that  required  to make  payment of the  securities  and pay any
servicing or other  fees).  The degree of credit  enhancement  provided for each
issue generally is based on historical information regarding the level of credit
risk  associated  with the underlying  assets.  Delinquency or loss in excess of
that  anticipated  could adversely  affect the return on an investment in such a
security.

         SPECIAL CHARACTERISTICS OF MORTGAGE- AND ASSET-BACKED SECURITIES -- The
yield characteristics of mortgage- and asset-backed securities differ from those
of traditiona1  debt securities.  Among the major  differences are that interest
and  principal  payments are made more  frequently,  usually  monthly,  and that
principal may be prepaid at any time because the  underlying  mortgage  loans or
other obligations generally may be prepaid at any time. Prepayments on a pool of
mortgage loans are influenced by a variety of economic,  geographic,  social and
other factors,  including  changes in mortgagors'  housing needs, job transfers,
unemployment,  mortgagors' net equity in the mortgaged  properties and servicing
decisions.  Generally,  however,  prepayments on fixed-rate  mortgage loans will
increase during a period of falling  interest rates and decrease during a period
of rising interest  rates.  Similar factors apply to prepayments on asset-backed
securities, but the receivables underlying asset-backed securities generally are
of a  shorter  maturity  and thus  are less  likely  to  experience  substantial
prepayments.  Such securities,  however, often provide that for a specified time
period the issuers  will  replace  receivables  in the pool that are repaid with
comparable obligations. If the issuer is unable to do so, repayment of principal
on the  asset-backed  securities may commence at an earlier date.  Mortgage- and
asset-backed  securities  may  decrease  in value as a result  of  increases  in
interest  rates and may benefit  less than other  fixed-income  securities  from
declining interest rates because of the risk of prepayment.

         The rate of interest on  mortgage-backed  securities  is lower than the
interest rates paid on the mortgages  included in the underlying pool due to the
annual  fees paid to the  servicer  of the  mortgage  pool for  passing  through
monthly  payments to  certificateholders  and to any  guarantor,  and due to any
yield  retained  by the  issuer.  Actual  yield to the  holder may vary from the
coupon rate, even if adjustable, if the mortgage-backed securities are purchased
or traded in the secondary market at a premium or discount.  In addition,  there
is normally some delay between the time the issuer  receives  mortgage  payments
from  the   servicer  and  the  time  the  issuer  makes  the  payments  on  the
mortgage-backed  securities,  and this delay reduces the effective  yield to the
holder of such securities.

         Yields on  pass-through  securities are typically  quoted by investment
dealers and vendors based on the maturity of the underlying  instruments and the
associated  average  life  assumption.  The average life of  pass-through  pools
varies with the maturities of the underlying  mortgage  loans. A pool's term may
be shortened by  unscheduled  or early  payments of principal on the  underlying
mortgages.  Because  prepayment rates of individual pools vary widely, it is not
possible to predict  accurately  the average life of a particular  pool.  In the
past,  a common  industry  practice was to assume that  prepayments  on pools of
fixed-rate  30-year  mortgages  would  result in a 12-year  average life for the
pool.  At  present,  mortgage  pools,  particularly  those with loans with other
maturities or different characteristics,  are priced on an assumption of average
life determined for each pool. In periods of declining  interest rates, the rate
of prepayment tends to increase, thereby shortening the actual average life of a
pool of mortgage-related  securities.  Conversely, in periods of rising interest
rates, the rate of prepayment tends to decrease,  thereby lengthening the actual
average  life of the pool.  However,  these  effects may not be present,  or may
differ in degree,  if the mortgage loans in the pools have  adjustable  interest
rates or other  special  payment  terms,  such as a  prepayment  charge.  Actual
prepayment  experience  may  cause the yield of  mortgage-backed  securities  to
differ from the assumed  average life yield.  Reinvestment  of  prepayments  may
occur at lower  interest  rates than the  original  investment,  thus  adversely
affecting a fund's yield.

         ADJUSTABLE RATE MORTGAGE AND FLOATING RATE  MORTGAGE-BACKED  SECURITIES
-- Adjustable rate mortgage ("ARM") securities (sometimes referred to as "ARMs")
are  mortgage-backed  securities  that  represent  a right to  receive  interest
payments at a rate that is adjusted to reflect the interest  earned on a pool of
mortgage loans bearing variable or adjustable  rates of interest.  Floating rate
mortgage-backed  securities are classes of mortgage-backed  securities that have
been  structured  to represent the right to receive  interest  payments at rates
that  fluctuate in accordance  with an index but that generally are supported by
pools comprised of fixed-rate mortgage loans.  Because the interest rates on ARM
and floating rate mortgage-backed securities are reset in response to changes in
a  specified  market  index,  the  values  of  such  securities  tend to be less
sensitive  to  interest  rate   fluctuations   than  the  values  of  fixed-rate
securities. As a result, during periods of rising interest rates, ARMs generally
do not decrease in value as much as fixed-rate  securities.  Conversely,  during
periods of declining  rates,  ARMs generally do not increase in value as much as
fixed-rate securities.  ARMs represent a right to receive interest payments at a
rate that is  adjusted to reflect  the  interest  earned on a pool of ARM loans.
These mortgage loans  generally  specify that the borrower's  mortgage  interest
rate may not be adjusted  above a specified  lifetime  maximum  rate or, in some
cases,  below a minimum  lifetime  rate. In addition,  certain ARM loans specify
limitations on the maximum amount by which the mortgage interest rate may adjust
for any single adjustment period. These mortgage loans also may limit changes in
the maximum  amount by which the borrower's  monthly  payment may adjust for any
single adjustment  period. In the event that a monthly payment is not sufficient
to pay the interest  accruing on the ARM loan, any such excess interest is added
to the mortgage loan ("negative  amortization"),  which is repaid through future
payments.  If a monthly payment  exceeds the sum of the interest  accrued at the
applicable mortgage interest rate and the principal payment that would have been
necessary to amortize the outstanding  principal balance over the remaining term
of the loan, the excess reduces the principal balance of the ARM loan. Borrowers
under these mortgage loans experiencing negative amortization may take longer to
build up their  equity  in the  underlying  property  and may be more  likely to
default.

         ARM loans  also may be subject to a greater  rate of  prepayments  in a
declining interest rate environment.  For example,  during a period of declining
interest rates,  prepayments on ARMs could increase  because the availability of
fixed-rate mortgage loans at competitive interest rates may encourage mortgagors
to "lock-in" at a lower  interest  rate.  Conversely,  during a period of rising
interest rates, prepayments on ARM loans might decrease. The rate of prepayments
with respect to ARM loans has fluctuated in recent years.

         The rates of interest  payable on certain ARM loans,  and  therefore on
certain ARM  securities,  are based on indices,  such as the  one-year  constant
maturity  Treasury rate, that reflect  changes in market interest rates.  Others
are based on indices,  such as the 11th District  Federal Home Loan Bank Cost of
Funds Index ("COFI"),  that tend to lag behind changes in market interest rates.
The values of ARM securities supported by ARM loans that adjust based on lagging
indices tend to be somewhat more  sensitive to interest rate  fluctuations  than
those reflecting  current interest rate levels,  although the values of such ARM
securities  still tend to be less sensitive to interest rate  fluctuations  than
fixed-rate securities.

         Floating rate mortgage-backed securities are classes of mortgage-backed
securities that have been structured to represent the right to receive  interest
payments at rates that fluctuate in accordance  with an index but that generally
are  supported by pools  comprised of  fixed-rate  mortgage  loans.  As with ARM
securities,   interest  rate   adjustments  on  floating  rate   mortgage-backed
securities  may be based on  indices  that lag  behind  market  interest  rates.
Interest  rates  on  floating  rate  mortgage-backed  securities  generally  are
adjusted  monthly.  Floating  rate  mortgage-backed  securities  are  subject to
lifetime  interest rate caps,  but they generally are not subject to limitations
on monthly or other periodic changes in interest rates or monthly payments.

         INVESTING IN FOREIGN  SECURITIES.  Investing in foreign  securities may
involve  more  risks than  investing  in U.S.  securities.  The value of foreign
securities  is subject to economic and political  developments  in the countries
where the issuers operate and to changes in foreign currency values. Investments
in foreign securities  involve risks relating to political,  social and economic
developments abroad, as well as risks resulting from the differences between the
regulations  to which U.S. and foreign  issuers and markets are  subject.  These
risks may include  expropriation,  confiscatory  taxation,  withholding taxes on
interest and/or dividends,  limitations on the use of or transfer of fund assets
and  political  or social  instability  or  diplomatic  developments.  Moreover,
individual  foreign  economies may differ favorably or unfavorably from the U.S.
economy in such respects as growth of gross national product, rate of inflation,
capital  reinvestment,   resource   self-sufficiency  and  balance  of  payments
position.  In  those  European  countries  that are  using  the Euro as a common
currency unit,  individual  national  economies may be adversely affected by the

                                       17
<PAGE>

inability of national  governments  to use monetary  policy to address their own
economic or political concerns.

         Securities  of many  foreign  companies  may be less  liquid  and their
prices more volatile than securities of comparable U.S. companies.  From time to
time  foreign   securities  may  be  difficult  to  liquidate   rapidly  without
significantly  depressing  the price of such  securities.  Foreign  markets have
different clearance and settlement procedures, and in certain markets there have
been  times  when  settlements  have  failed  to keep  pace  with the  volume of
securities  transactions,  making it  difficult  to conduct  such  transactions.
Delays in  settlement  could result in  temporary  periods when some of a fund's
assets are uninvested and no return is earned  thereon.  The inability of a fund
to make intended security  purchases due to settlement  problems could cause the
fund to miss  attractive  investment  opportunities.  Inability  to dispose of a
portfolio  security due to settlement  problems could result either in losses to
the fund due to subsequent  declines in the value of such portfolio security or,
if the fund has entered  into a contract to sell the  security,  could result in
possible  liability to the  purchaser.  Foreign  securities  trading  practices,
including  those  involving  securities  settlement  where  fund  assets  may be
released prior to receipt of payment, may expose a fund to increased risk in the
event of a failed  trade or the  insolvency  of a foreign  broker-dealer.  Legal
remedies for  defaults  and  disputes may have to be pursued in foreign  courts,
whose procedures differ substantially from those of U.S. courts.

         The costs of investing  outside the United States frequently are higher
than those attributable to investing in the United States.  This is particularly
true  with  respect  to  emerging  capital  markets.  For  example,  the cost of
maintaining  custody of foreign  securities exceeds custodian costs for domestic
securities, and transaction and settlement costs of foreign investing frequently
are higher than those attributable to domestic investing.  Costs associated with
the exchange of  currencies  also make foreign  investing  more  expensive  than
domestic investing.

         Securities of foreign  issuers may not be registered  with the SEC, and
the  issuers  thereof  may  not  be  subject  to  its  reporting   requirements.
Accordingly, there may be less publicly available information concerning foreign
issuers  of  securities  held  by a  fund  than  is  available  concerning  U.S.
companies.  Foreign companies are not generally  subject to uniform  accounting,
auditing and financial reporting  standards or to other regulatory  requirements
comparable to those applicable to U.S. companies.

         A fund may  invest  in  foreign  securities  by  purchasing  depositary
receipts,  including American Depositary Receipts ("ADRs"),  European Depositary
Receipts ("EDRs") and Global Depositary  Receipts ("GDRs"),  or other securities
convertible  into  securities  of  issuers  based in  foreign  countries.  These
securities  may not  necessarily  be  denominated  in the same  currency  as the
securities into which they may be converted.  ADRs are receipts typically issued
by a  U.S.  bank  or  trust  company  evidencing  ownership  of  the  underlying
securities.  They  generally are in registered  form,  are  denominated  in U.S.
dollars  and are  designed  for use in the  U.S.  securities  markets.  EDRs are
European receipts evidencing a similar arrangement,  may be denominated in other
currencies  and are designed for use in European  securities  markets.  GDRs are
similar  to EDRs and are  designed  for use in several  international  financial
markets.  For purposes of each fund's investment  policies,  depositary receipts
generally  are  deemed  to  have  the  same  classification  as  the  underlying
securities they represent.  Thus, a depositary receipt representing ownership of
common stock will be treated as common stock.

         ADRs are publicly traded on exchanges or over-the-counter in the United
States and are issued through  "sponsored" or "unsponsored"  arrangements.  In a
sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some
or all of the  depositary's  transaction  fees,  whereas  under  an  unsponsored
arrangement,  the foreign  issuer assumes no  obligations  and the  depositary's
transaction  fees  are paid  directly  by the ADR  holders.  In  addition,  less
information  is available in the United  States  about an  unsponsored  ADR than
about a sponsored ADR.

         The funds that invest outside the United States  anticipate  that their
brokerage transactions  involving foreign securities of companies  headquartered
in countries  other than the United  States will be  conducted  primarily on the
principal exchanges of such countries.  Although a fund will endeavor to achieve
the best net results in effecting its portfolio  transactions,  transactions  on
foreign  exchanges are usually subject to fixed  commissions  that are generally
higher than negotiated commissions on U.S. transactions. There is generally less
government  supervision  and  regulation  of  exchanges  and  brokers in foreign
countries than in the United States.


                                       18
<PAGE>

         Substantial  limitations may exist in certain countries with respect to
the funds' ability to repatriate  investment capital or the proceeds of sales of
securities.

         FOREIGN  CURRENCY  RISKS.  Currency  risk is the risk that  changes  in
foreign  exchange  rates may reduce the U.S.  dollar  value of a fund's  foreign
investments.  If the value of a foreign  currency rises against the value of the
U.S.  dollar,  the value of a fund's  investments  that are  denominated  in, or
linked to, that currency will  increase.  Conversely,  if the value of a foreign
currency  declines against the value of the U.S. dollar,  the value of such fund
investments  will decrease.  These changes may have a significant  impact on the
value of fund shares. In some instances, a fund may use derivative strategies to
hedge  against  changes  in  foreign  currency  value.  (See  "Strategies  Using
Derivative  Instruments,"  below.)  However,   opportunities  to  hedge  against
currency  risk may not exist in certain  markets,  particularly  with respect to
emerging market currencies,  and even when appropriate hedging opportunities are
available, a fund may choose not to hedge against currency risk.

         Generally,  currency exchange rates are determined by supply and demand
in the  foreign  exchange  markets and the  relative  merits of  investments  in
different  countries.  In the case of those European countries that use the Euro
as a common  currency  unit,  the relative  merits of  investments in the common
market in which they  participate,  rather than the merits of investments in the
individual country,  will be a determinant of currency exchange rates.  Currency
exchange rates also can be affected by the  intervention of the U.S. and foreign
governments or central banks, the imposition of currency controls,  speculation,
devaluation or other political or economic  developments  inside and outside the
United States.

         Each fund values its assets daily in U.S. dollars,  and funds that hold
foreign  currencies  do not  intend to convert  them to U.S.  dollars on a daily
basis.  From time to time a fund's  foreign  currencies  may be held as "foreign
currency call accounts" at foreign branches of foreign or domestic banks.  These
accounts bear interest at negotiated rates and are payable upon relatively short
demand periods.  If a bank became insolvent,  a fund could suffer a loss of some
or all of the amounts deposited.  Each fund may convert foreign currency to U.S.
dollars from time to time.

         The U.S.  dollar value of fund assets that are  denominated  in foreign
currencies may be affected  favorably or unfavorably by fluctuations in currency
rates and  exchange  control  regulations.  Further,  a fund may incur  costs in
connection  with  conversions  between  various  currencies.  Currency  exchange
dealers  realize a profit  based on the  difference  between the prices at which
they are buying and selling  various  currencies.  Thus, a dealer  normally will
offer to sell a foreign  currency to a fund at one rate, while offering a lesser
rate of exchange should a fund desire immediately to resell that currency to the
dealer. Funds that conduct currency exchange transactions do so either on a spot
(i.e.,  cash) basis at the spot rate prevailing in the foreign currency exchange
market or  through  entering  into  forward,  futures or  options  contracts  to
purchase or sell foreign currencies.

         EMERGING MARKET INVESTMENTS.  The special risks of investing in foreign
securities are heightened in emerging markets. For example, many emerging market
currencies recently have experienced  significant  devaluations  relative to the
U.S. dollar in recent years.  Emerging market countries  typically have economic
and  political  systems that are less fully  developed and can be expected to be
less stable than those of developed  countries.  Emerging  market  countries may
have policies that restrict investment by foreigners, and there is a higher risk
of  government   expropriation  or  nationalization  of  private  property.  The
possibility of low or nonexistent  trading volume in the securities of companies
in  emerging  markets  also  may  result  in a lack of  liquidity  and in  price
volatility.  Issuers in  emerging  markets  typically  are  subject to a greater
degree of change in earnings and business  prospects  than are companies in more
developed markets.

         INVESTMENT AND REPATRIATION  RESTRICTIONS -- Foreign  investment in the
securities  markets  of several  emerging  market  countries  is  restricted  or
controlled to varying degrees.  These restrictions may limit a fund's investment
in these countries and may increase its expenses. For example, certain countries
may require  governmental  approval prior to investments by foreign persons in a
particular  company or industry sector or limit investment by foreign persons to
only  a  specific  class  of  securities  of a  company,  which  may  have  less
advantageous  terms (including  price) than securities of the company  available
for purchase by nationals. Certain countries may restrict or prohibit investment
opportunities in issuers or industries  deemed important to national  interests.
In addition,  the  repatriation of both investment  income and capital from some
emerging  market  countries  is  subject to  restrictions,  such as the need for
certain  government  consents.  Even where there is no outright  restriction  on
repatriation  of capital,  the  mechanics  of  repatriation  may affect  certain
aspects of a fund's  operations.  These  restrictions  may in the future make it

                                       19
<PAGE>

undesirable  to invest in the  countries to which they apply.  In  addition,  if
there is a  deterioration  in a  country's  balance  of  payments  or for  other
reasons,  a country  may  impose  restrictions  on foreign  capital  remittances
abroad. A fund could be adversely  affected by delays in, or a refusal to grant,
any  required  governmental  approval  for  repatriation,  as  well  as  by  the
application to it of other restrictions on investments.

         If, because of restrictions on repatriation or conversion,  a fund were
unable to distribute  substantially all of its net investment income and capital
gains  within  applicable  time  periods,  the fund  would be subject to federal
income  and/or excise taxes that would not otherwise be incurred and could cease
to qualify for the  favorable  tax  treatment  afforded to regulated  investment
companies  under the Internal  Revenue Code. If it did cease to qualify for that
treatment,  it would become  subject to federal  income tax on all of its income
and net gains. See "Taxes -- Qualification as a Regulated  Investment  Company,"
below.

         DIFFERENCES  BETWEEN THE U.S. AND EMERGING MARKET  SECURITIES  MARKETS.
Most of the securities  markets of emerging market countries have  substantially
less  volume than the New York Stock  Exchange,  and equity  securities  of most
companies in emerging  market  countries  are less liquid and more volatile than
equity  securities  of U.S.  companies  of  comparable  size.  Some of the stock
exchanges  in emerging  market  countries  are in the  earliest  stages of their
development.  As a  result,  securities  settlements  may in some  instances  be
subject to delays and related administrative uncertainties. Many companies whose
securities  are traded on securities  markets in emerging  market  countries are
smaller,  newer and less seasoned than companies whose  securities are traded on
securities  markets  in the United  States.  Investments  in  smaller  companies
involve  greater risk than is  customarily  associated  with investing in larger
companies.  Smaller  companies  may  have  limited  product  lines,  markets  or
financial or  managerial  resources  and may be more  susceptible  to losses and
risks of bankruptcy.  Additionally,  market-making and arbitrage  activities are
generally  less  extensive in such  markets,  which may  contribute to increased
volatility  and reduced  liquidity of such markets.  Accordingly,  each of these
markets  may be  subject  to  greater  influence  by  adverse  events  generally
affecting  the market,  and by large  investors  trading  significant  blocks of
securities,  than is usual in the United States.  To the extent that an emerging
market country experiences rapid increases in its money supply and investment in
equity securities for speculative purposes, the equity securities traded in that
country may trade at  price-earnings  multiples  higher than those of comparable
companies trading on securities  markets in the United States,  which may not be
sustainable.

         GOVERNMENT  SUPERVISION OF EMERGING MARKET  SECURITIES  MARKETS;  LEGAL
SYSTEMS.  There is also less government supervision and regulation of securities
exchanges, listed companies and brokers in emerging market countries than exists
in the United States.  Therefore,  less  information  may be available to a fund
than with  respect to  investments  in the United  States.  Further,  in certain
countries,  less  information  may be  available  to a fund than to local market
participants. Brokers in other countries may not be as well capitalized as those
in the United States,  so that they are more susceptible to financial failure in
times of market,  political or economic stress.  In addition,  existing laws and
regulations are often  inconsistently  applied.  As legal systems in some of the
emerging market countries  develop,  foreign investors may be adversely affected
by new laws and  regulations,  changes  to  existing  laws and  regulations  and
preemption of local laws and  regulations  by national  laws.  In  circumstances
where adequate laws exist,  it may not be possible to obtain swift and equitable
enforcement of the law.

         SOCIAL,   POLITICAL  AND  ECONOMIC  FACTORS  --  Many  emerging  market
countries may be subject to a greater  degree of social,  political and economic
instability than is the case in the United States.  Any change in the leadership
or  policies  of these  countries  may  halt the  expansion  of or  reverse  any
liberalization of foreign  investment  policies now occurring.  Such instability
may  result  from,  among  other  things,   the  following:   (1)  authoritarian
governments or military  involvement in political and economic  decision making,
and changes in government through extra-constitutional means; (2) popular unrest
associated with demands for improved political,  economic and social conditions;
(3) internal insurgencies; (4) hostile relations with neighboring countries; and
(5) ethnic,  religious  and racial  disaffection.  Such  social,  political  and
economic instability could significantly  disrupt the financial markets in those
countries and elsewhere and could adversely affect the value of a fund's assets.
In addition,  there may be the  possibility  of asset  expropriations  or future
confiscatory levels of taxation affecting a fund.

         The  economies  of many  emerging  markets are heavily  dependent  upon
international  trade and are accordingly  affected by protective  trade barriers

                                       20
<PAGE>

and the economic  conditions of their trading  partners,  principally the United
States,  Japan, China and the European Union. The enactment by the United States
or  other  principal  trading  partners  of  protectionist   trade  legislation,
reduction of foreign  investment in the local economies and general  declines in
the  international  securities  markets could have a significant  adverse effect
upon the securities  markets of these countries.  In addition,  the economies of
some  countries are  vulnerable to weakness in world prices for their  commodity
exports,  including crude oil. A country whose exports are concentrated in a few
commodities could be vulnerable to a decline in the international  price of such
commodities.

         Emerging  markets  include  formerly  communist  countries  of  Eastern
Europe,  Russia and the other  countries that once formed the Soviet Union,  and
China. Upon the accession to power of communist  regimes  approximately 50 to 80
years ago, the governments of a number of these countries  seized a large amount
of property.  The claims of many property owners against those  governments were
never finally  settled.  There can be no guarantee that a fund's  investments in
these  countries,  if any, would not also be seized or otherwise  taken away, in
which case the fund could lose its entire investment in the country involved.

         FINANCIAL INFORMATION AND LEGAL STANDARDS -- Issuers in emerging market
countries generally are subject to accounting,  auditing and financial standards
and requirements that differ, in some cases significantly, from those applicable
to U.S.  issuers.  In  particular,  the  assets  and  profits  appearing  on the
financial  statements of an emerging market issuer may not reflect its financial
position or results of  operations  in the way they would be  reflected  had the
financial  statements been prepared in accordance with U.S.  generally  accepted
accounting principles.  In addition, for an issuer that keeps accounting records
in local  currency,  inflation  accounting  rules may require,  for both tax and
accounting  purposes,  that certain  assets and  liabilities  be restated on the
issuer's  balance  sheet in  order to  express  items  in terms of  currency  of
constant purchasing power.  Inflation  accounting may indirectly generate losses
or  profits.  Consequently,   financial  data  may  be  materially  affected  by
restatements for inflation and may not accurately  reflect the real condition of
those issuers and securities markets.

         In addition,  existing laws and  regulations  are often  inconsistently
applied.  As legal  systems in some of the emerging  market  countries  develop,
foreign investors may be adversely affected by new laws and regulations, changes
to existing laws and regulations and preemption of local laws and regulations by
national  laws.  In  circumstances  where  adequate  laws  exist,  it may not be
possible to obtain swift and equitable enforcement of the law.

         FOREIGN  SOVEREIGN DEBT.  Sovereign debt includes bonds that are issued
by  foreign  governments  or  their  agencies,  instrumentalities  or  political
subdivisions or by foreign  central banks.  Sovereign debt also may be issued by
quasi-governmental  entities that are owned by foreign  governments  but are not
backed by their full faith and credit or general  taxing  powers.  Investment in
sovereign  debt  involves   special  risks.  The  issuer  of  the  debt  or  the
governmental authorities that control the repayment of the debt may be unable or
unwilling to repay  principal  and/or  interest when due in accordance  with the
terms of such debt,  and the funds may have limited legal  recourse in the event
of a default.

         Sovereign debt differs from debt obligations issued by private entities
in that,  generally,  remedies for defaults must be pursued in the courts of the
defaulting party.  Legal recourse is therefore  somewhat  diminished.  Political
conditions, especially a sovereign entity's willingness to meet the terms of its
debt  obligations,  are of  considerable  significance.  Also,  there  can be no
assurance that the holders of commercial  bank debt issued by the same sovereign
entity may not contest payments to the holders of sovereign debt in the event of
default under commercial bank loan agreements.

         A sovereign  debtor's  willingness  or ability to repay  principal  and
interest due in a timely  manner may be affected by,  among other  factors,  its
cash flow situation,  the extent of its foreign  reserves,  the  availability of
sufficient  foreign  exchange on the date a payment is due, the relative size of
the debt service burden to the economy as a whole, the sovereign debtor's policy
toward principal  international lenders and the political constraints to which a
sovereign  debtor may be subject.  A country whose exports are concentrated in a
few commodities could be vulnerable to a decline in the  international  price of
such  commodities.  Increased  protectionism on the part of a country's  trading
partners,  or political changes in those countries,  could also adversely affect
its exports.  Such events could diminish a country's trade account  surplus,  if
any, or the credit standing of a particular local government or agency.  Another
factor bearing on the ability of a country to repay  sovereign debt is the level
of the  country's  international  reserves.  Fluctuations  in the level of these

                                       21
<PAGE>

reserves  can  affect  the  amount of foreign  exchange  readily  available  for
external debt payments  and,  thus,  could have a bearing on the capacity of the
country to make payments on its sovereign debt.

         The  occurrence  of political,  social or diplomatic  changes in one or
more of the countries  issuing  sovereign debt could  adversely  affect a fund's
investments.  Political  changes  or a  deterioration  of a  country's  domestic
economy or balance of trade may affect the  willingness  of countries to service
their  sovereign  debt.  While Mitchell  Hutchins or the  sub-adviser  manages a
fund's  portfolio  in a manner that is intended to minimize the exposure to such
risks, there can be no assurance that adverse political changes will not cause a
fund to suffer a loss of  interest or  principal  on any of its  sovereign  debt
holdings.

         With respect to sovereign debt of emerging  market  issuers,  investors
should be aware that certain  emerging  market  countries  are among the largest
debtors to  commercial  banks and  foreign  governments.  Some  emerging  market
countries have from time to time declared  moratoria on the payment of principal
and interest on external debt.

         Some emerging market countries have experienced difficulty in servicing
their  sovereign  debt on a  timely  basis  which  led to  defaults  on  certain
obligations  and  the  restructuring  of  certain  indebtedness.   Restructuring
arrangements  have  included,  among other  things,  reducing  and  rescheduling
interest and principal  payments by negotiating new or amended credit agreements
or  converting   outstanding  principal  and  unpaid  interest  to  Brady  Bonds
(discussed  below),  and  obtaining  new  credit to finance  interest  payments.
Holders of sovereign debt,  including the funds, may be requested to participate
in the  rescheduling  of such  debt and to  extend  further  loans to  sovereign
debtors.  The interests of holders of sovereign debt could be adversely affected
in the course of restructuring arrangements or by certain other factors referred
to below.  Furthermore,  some of the  participants  in the secondary  market for
sovereign debt may also be directly  involved in negotiating  the terms of these
arrangements  and may,  therefore,  have access to information  not available to
other  market   participants.   Obligations   arising  from  past  restructuring
agreements  may  affect  the  economic  performance  and  political  and  social
stability  of  certain  issuers  of  sovereign  debt.  There  is  no  bankruptcy
proceeding  by which  sovereign  debt on which a sovereign  has defaulted may be
collected in whole or in part.

         Foreign   investment  in  certain   sovereign  debt  is  restricted  or
controlled to varying degrees. These restrictions or controls may at times limit
or preclude foreign investment in such sovereign debt and increase the costs and
expenses  of a fund.  Certain  countries  in  which a fund  may  invest  require
governmental approval prior to investments by foreign persons,  limit the amount
of investment by foreign persons in a particular issuer, limit the investment by
foreign  persons only to a specific  class of  securities  of an issuer that may
have less  advantageous  rights  than the  classes  available  for  purchase  by
domiciliaries of the countries or impose additional taxes on foreign  investors.
Certain  issuers may  require  governmental  approval  for the  repatriation  of
investment  income,  capital or the proceeds of sales of  securities  by foreign
investors.  In addition,  if a  deterioration  occurs in a country's  balance of
payments the country  could impose  temporary  restrictions  on foreign  capital
remittances.  A fund could be  adversely  affected by delays in, or a refusal to
grant, any required  governmental  approval for repatriation of capital, as well
as by the application to the fund of any restrictions on investments.  Investing
in local  markets may  require a fund to adopt  special  procedures,  seek local
government approvals or take other actions, each of which may involve additional
costs to the fund.

         BRADY  BONDS -- Brady  Bonds  are  sovereign  bonds  issued  under  the
framework of the Brady Plan,  an  initiative  announced by former U.S.  Treasury
Secretary  Nicholas  F.  Brady in 1989 as a  mechanism  for  debtor  nations  to
restructure  their  outstanding   external  commercial  bank  indebtedness.   In
restructuring its external debt under the Brady Plan framework,  a debtor nation
negotiates with its existing bank lenders as well as  multilateral  institutions
such as the International Monetary Fund ("IMF"). The Brady Plan framework, as it
has  developed,  contemplates  the  exchange of  commercial  bank debt for newly
issued Brady Bonds. Brady Bonds may also be issued in respect of new money being
advanced by existing  lenders in  connection  with the debt  restructuring.  The
World Bank and the IMF support the  restructuring by providing funds pursuant to
loan  agreements  or other  arrangements  which  enable  the  debtor  nation  to
collateralize  the new Brady Bonds or to repurchase  outstanding  bank debt at a
discount.

         Brady Bonds do not have a long payment history.  Agreements implemented
under the Brady  Plan to date are  designed  to  achieve  debt and  debt-service
reduction  through  specific  options  negotiated  by a debtor  nation  with its
creditors.  As a result,  the financial packages offered by each country differ.
The types of options have included the exchange of outstanding  commercial  bank
debt  for  bonds  issued  at 100% of face  value  of such  debt,  which  carry a
below-market  stated rate of  interest  (generally  known as par  bonds),  bonds


                                    22
<PAGE>

issued  at a  discount  from the face  value of such  debt  (generally  known as
discount  bonds),  bonds bearing an interest rate which  increases over time and
bonds issued in exchange for the  advancement of new money by existing  lenders.
Regardless  of the stated  face amount and stated  interest  rate of the various
types of Brady Bonds,  a fund will  purchase  Brady Bonds in which the price and
yield to the investor reflect market conditions at the time of purchase.

         Certain  Brady Bonds have been  collateralized  as to principal  due at
maturity by U.S.  Treasury zero coupon bonds with maturities  equal to the final
maturity of such Brady Bonds.  Collateral purchases are financed by the IMF, the
World  Bank and the debtor  nations'  reserves.  In the event of a default  with
respect  to  collateralized  Brady  Bonds  as a  result  of  which  the  payment
obligations  of the  issuer  are  accelerated,  the U.S.  Treasury  zero  coupon
obligations  held as  collateral  for  the  payment  of  principal  will  not be
distributed  to investors,  nor will such  obligations  be sold and the proceeds
distributed.  The  collateral  will be held by the  collateral  agent  until the
scheduled  maturity of the  defaulted  Brady  Bonds,  which will  continue to be
outstanding,  at which  time the face  amount of the  collateral  will equal the
principal  payments  that  would  have then  been due on the Brady  Bonds in the
normal course.  Interest payments on Brady Bonds may be wholly  uncollateralized
or may be  collateralized  by cash or high  grade  securities  in  amounts  that
typically  represent  between  12 and 18 months of  interest  accruals  on these
instruments, with the balance of the interest accruals being uncollateralized.

         Brady Bonds are often viewed as having  several  valuation  components:
(1) the collateralized  repayment of principal,  if any, at final maturity,  (2)
the collateralized interest payments, if any, (3) the uncollateralized  interest
payments and (4) any uncollateralized  repayment of principal at maturity (these
uncollateralized  amounts  constitute  the  "residual  risk").  In  light of the
residual risk of Brady Bonds and, among other  factors,  the history of defaults
with  respect  to  commercial  bank  loans by public  and  private  entities  of
countries  issuing Brady Bonds,  investments  in Brady Bonds are to be viewed as
speculative.   A  fund   may   purchase   Brady   Bonds   with  no  or   limited
collateralization and will be relying for payment of interest and (except in the
case of principal  collateralized  Brady Bonds) repayment of principal primarily
on the  willingness  and ability of the foreign  government  to make  payment in
accordance with the terms of the Brady Bonds.

         STRUCTURED FOREIGN INVESTMENTS. This term generally refers to interests
in U.S. and foreign  entities  organized and operated  solely for the purpose of
securitizing  or  restructuring  the  investment   characteristics   of  foreign
securities.  This type of securitization  or restructuring  usually involves the
deposit with or purchase by a U.S. or foreign  entity,  such as a corporation or
trust, of specified  instruments  (such as commercial bank loans or Brady Bonds)
and the issuance by that entity of one or more classes of securities  backed by,
or representing interests in, the underlying  instruments.  The cash flow on the
underlying  instruments  may be  apportioned  among the newly issued  structured
foreign   investments   to   create   securities   with   different   investment
characteristics such as varying maturities, payment priorities and interest rate
provisions,  and the extent of the  payments  made with  respect  to  structured
foreign  investments  is often  dependent  on the extent of the cash flow on the
underlying instruments.

         Structured   foreign   investments   frequently   involve   no   credit
enhancement. Accordingly, their credit risk generally will be equivalent to that
of the  underlying  instruments.  In  addition,  classes of  structured  foreign
investments  may be  subordinated  to the right of  payment  of  another  class.
Subordinated  structured  foreign  investments  typically have higher yields and
present  greater  risks  than  unsubordinated  structured  foreign  investments.
Structured   foreign   investments  are  typically  sold  in  private  placement
transactions,  and there  currently is no active  trading  market for structured
foreign investments.

         CURRENCY-LINKED  INVESTMENTS.  The principal  amount of securities that
are indexed to specific  foreign  currency  exchange rates may be adjusted up or
down (but not below zero) at maturity to reflect  changes in the  exchange  rate
between two  currencies.  A fund may  experience  loss of principal due to these
adjustments.

         INVESTMENTS  IN OTHER  INVESTMENT  COMPANIES.  Each fund may  invest in
securities  of other  investment  companies,  subject to  limitations  under the
Investment Company Act. Among other things, these limitations currently restrict
a fund's aggregate investments in other investment companies to no more than 10%
of its total assets. A fund's investments in certain private investment vehicles
are not subject to this  restriction.  The shares of other investment  companies
are subject to the management  fees and other expenses of those  companies,  and
the  purchase of shares of some  investment  companies  requires  the payment of
sales  loads  and (in the case of  closed-end  investment  companies)  sometimes
substantial premiums above the value of those companies'  portfolio  securities.
At the same  time,  a fund would  continue  to pay its own  management  fees and

                                       23
<PAGE>

expenses  with  respect  to all  its  investments,  including  shares  of  other
investment  companies.  Each fund may invest in the  shares of other  investment
companies  when,  in  the  judgment  of  Mitchell  Hutchins  or  the  applicable
sub-adviser,  the potential  benefits of the investment  outweigh the payment of
any management fees and expenses and, where applicable, premium or sales load.

         From time to time, investments in other investment companies may be the
most effective  available means for a fund to invest a portion of its assets. In
some cases,  investment in another  investment company may be the most practical
way for a fund to invest in  securities of issuers in certain  countries.  These
investments  may include  World Equity  Benchmark  SharesSM  (commonly  known as
"WEBS"),  which are  exchange-traded  shares of series of an investment  company
that are designed to  replicate  the  composition  and  performance  of publicly
traded issuers in particular foreign  countries.  A fund's investment in another
investment  company  is  subject  to the  risks  of  that  investment  company's
underlying portfolio securities.  Shares of exchange-traded investment companies
also can  trade at  substantial  discounts  below  the  value of the  companies'
portfolio securities.

         Money  Market  Portfolio  may invest in the  securities  of other money
market funds when Mitchell Hutchins believes that (1) the amounts to be invested
are too small or are available too late in the day to be effectively invested in
money market instruments, (2) shares of other money market funds otherwise would
provide a better return than direct  investment in money market  instruments  or
(3) such  investments  would enhance the fund's  liquidity.  The other funds may
invest in the securities of money market funds for similar reasons.

         ZERO  COUPON AND OTHER OID  SECURITIES;  PIK  SECURITIES.  Zero  coupon
securities  are securities on which no periodic  interest  payments are made but
instead are issued at a deep discount from their  maturity  value.  The buyer of
these  securities  receives a rate of return by the gradual  appreciation of the
security,  which  results  from the fact that it will be paid at face value on a
specified  maturity date. There are many types of zero coupon  securities.  Some
are issued in zero coupon form,  including  Treasury bills, notes and bonds that
have  been  stripped  of  (separated  from)  their  unmatured  interest  coupons
(unmatured   interest  payments)  and  receipts  or  certificates   representing
interests in such stripped debt  obligations and coupons.  Others are created by
brokerage firms that strip the coupons from  interest-paying  bonds and sell the
principal and the coupons separately.

         Other  securities  that are sold with original issue  discount  ("OID")
(i.e.,  the  difference  between the issue price and the value at maturity)  may
provide  for  some  interest  to  be  paid  prior  to  maturity.   In  addition,
payment-in-kind ("PIK") securities pay interest in additional securities, not in
cash. OID and PIK securities usually trade at a discount from their face value.

         Zero coupon  securities  are  generally  more  sensitive  to changes in
interest rates than debt obligations of comparable  maturities that make current
interest  payments.  This means that when interest rates fall, the value of zero
coupon  securities  rises more  rapidly  than  securities  paying  interest on a
current  basis.  However,  when  interest  rates  rise,  their  value falls more
dramatically.  Other OID  securities  and PIK  securities  also are  subject  to
greater fluctuations in market value in response to changing interest rates than
bonds of comparable  maturities that make current  distributions  of interest in
cash.

         Because federal tax law requires that accrued OID and "interest" on PIK
securities must be included in a fund's current income (see "Taxes,"  below),  a
fund might be  required  to  distribute  as a dividend an amount that is greater
than the total amount of cash it actually receives.  These  distributions  would
have to be made from the fund's cash assets or, if necessary,  from the proceeds
of  sales  of  portfolio  securities.  A fund  would  not be  able  to  purchase
additional securities with cash used to make these distributions and its current
income and the value of its shares would ultimately be reduced as a result.

         Certain zero coupon  securities are U.S.  Treasury notes and bonds that
have been stripped of their  unmatured  interest coupon receipts or interests in
such U.S. Treasury  securities or coupons.  The staff of the SEC currently takes
the position that  "stripped"  U.S.  government  securities  that are not issued
through the U.S. Treasury are not U.S. government securities.  This technique is
frequently used with U.S.  Treasury bonds to create CATS (Certificate of Accrual
Treasury  Securities),  TIGRs  (Treasury  Income  Growth  Receipts)  and similar
securities.

         CONVERTIBLE  SECURITIES.  A convertible  security is a bond,  preferred
stock or other security that may be converted into or exchanged for a prescribed

                                       24
<PAGE>

amount of common  stock of the same or a different  issuer  within a  particular
period of time at a specified price or formula. A convertible  security entitles
the holder to receive  interest  or  dividends  until the  convertible  security
matures or is redeemed,  converted or  exchanged.  Convertible  securities  have
unique investment  characteristics in that they generally (1) have higher yields
than common stocks, but lower yields than comparable non-convertible securities,
(2) are less subject to fluctuation  in value than the underlying  stock because
they have fixed income characteristics and (3) provide the potential for capital
appreciation if the market price of the underlying common stock increases. While
no  securities  investment  is without  some risk,  investments  in  convertible
securities  generally entail less risk than the issuer's common stock.  However,
the  extent to which  such risk is reduced  depends  in large  measure  upon the
degree to which the convertible security sells above its value as a fixed income
security.

         A  convertible  security may be subject to  redemption at the option of
the  issuer  at a price  established  in the  convertible  security's  governing
instrument.  If a convertible  security held by a fund is called for redemption,
the fund will be required to permit the issuer to redeem the  security,  convert
it into the underlying common stock or sell it to a third party.

         LOAN   PARTICIPATIONS  AND  ASSIGNMENTS.   Investments  in  secured  or
unsecured  fixed or  floating  rate loans  ("Loans")  arranged  through  private
negotiations between a borrowing corporation, government or other entity and one
or more financial institutions  ("Lenders") may be in the form of participations
("Participations")  in Loans or assignments  ("Assignments") of all or a portion
of Loans  from  third  parties.  Participations  typically  result in the fund's
having a contractual relationship only with the Lender, not with the borrower. A
fund has the right to receive  payments of  principal,  interest and any fees to
which it is entitled  only from the Lender  selling the  Participation  and only
upon receipt by the Lender of the payments from the borrower. In connection with
purchasing  Participations,  a fund  generally  has no direct  right to  enforce
compliance by the borrower with the terms of the loan agreement  relating to the
Loan,  nor any  rights  of  set-off  against  the  borrower,  and a fund may not
directly  benefit  from  any  collateral  supporting  the  Loan in  which it has
purchased the Participation. As a result, a fund assumes the credit risk of both
the borrower and the Lender that is selling the  Participation.  In the event of
the  insolvency  of the  selling  Lender,  the fund may be  treated as a general
creditor of that Lender and may not benefit from any set-off  between the Lender
and the borrower.  A fund will acquire  Participations only if Mitchell Hutchins
or  the   applicable   sub-adviser   determines   that  the  selling  Lender  is
creditworthy.

         When a fund  purchases  Assignments  from Lenders,  it acquires  direct
rights against the borrower on the Loan. In an Assignment,  the fund is entitled
to receive payments directly from the borrower and,  therefore,  does not depend
on the  selling  bank to pass these  payments  onto the fund.  However,  because
Assignments  are  arranged  through  private   negotiations   between  potential
assignees and assignors,  the rights and obligations acquired by the fund as the
purchaser of an Assignment may differ from, and be more limited than, those held
by the assigning Lender.

         Assignments and  Participations  are generally not registered under the
Securities Act of 1933, as amended  ("Securities  Act"), and thus may be subject
to a fund's limitation on investment in illiquid  securities.  Because there may
be no liquid market for such  securities,  such securities may be sold only to a
limited number of institutional investors. The lack of a liquid secondary market
could have an  adverse  impact on the value of such  securities  and on a fund's
ability to dispose of particular Assignments or Participations when necessary to
meet the fund's  liquidity  needs or in response to a specific  economic  event,
such as a deterioration in the creditworthiness of the borrower.

         TEMPORARY AND DEFENSIVE  INVESTMENTS;  MONEY MARKET  INVESTMENTS.  Each
fund may invest in money market investments for temporary or defensive purposes,
to reinvest cash collateral from its securities lending activities or as part of
its normal  investment  program.  Except for Money Market Portfolio and Balanced
Fund (whose money market investments are described elsewhere),  such investments
include,  among other things,  (1)  securities  issued or guaranteed by the U.S.
government or one of its agencies or instrumentalities,  (2) debt obligations of
banks, savings and loan institutions,  insurance companies and mortgage bankers,
(3) commercial paper and notes, including those with variable and floating rates
of  interest,  (4) debt  obligations  of foreign  branches of U.S.  banks,  U.S.
branches of foreign  banks,  and foreign  branches  of foreign  banks,  (5) debt
obligations  issued or guaranteed by one or more foreign  governments  or any of
their foreign political subdivisions,  agencies or instrumentalities,  including
obligations of supranational  entities, (6) bonds issued by foreign issuers, (7)
repurchase agreements and (8) other investment companies that invest exclusively

                                       25
<PAGE>

in money market instruments and similar private investment vehicles.  Only those
funds  that may invest  outside  the  United  States may invest in money  market
instruments that are denominated in foreign currencies.

         WARRANTS.  Warrants  are  securities  permitting,  but not  obligating,
holders to subscribe for other  securities.  Warrants do not carry with them the
right to dividends or voting  rights with  respect to the  securities  that they
entitle  their holder to purchase,  and they do not  represent any rights in the
assets of the issuer.  As a result,  warrants may be considered more speculative
than certain  other types of  investments.  In addition,  the value of a warrant
does not necessarily change with the value of the underlying  securities,  and a
warrant  ceases to have  value if it is not  exercised  prior to its  expiration
date.

         ILLIQUID SECURITIES. The term "illiquid securities" for purposes of the
Prospectus and SAI means securities that cannot be disposed of within seven days
in the ordinary course of business at  approximately  the amount at which a fund
has  valued  the  securities  and  includes,   among  other  things,   purchased
over-the-counter options, repurchase agreements maturing in more than seven days
and restricted  securities other than those Mitchell  Hutchins or the applicable
sub-adviser has determined are liquid pursuant to guidelines  established by the
board. The assets used as cover for  over-the-counter  options written by a fund
will be  considered  illiquid  unless the  over-the-counter  options are sold to
qualified  dealers that agree that the fund may repurchase any  over-the-counter
options it writes at a maximum  price to be calculated by a formula set forth in
the option agreements.  The cover for an over-the-counter option written subject
to this  procedure  would be  considered  illiquid  only to the extent  that the
maximum  repurchase  price under the formula  exceeds the intrinsic value of the
option.  Under current SEC guidelines,  interest only and principal only classes
of  mortgage-backed  securities  generally  are  considered  illiquid.  However,
interest  only  and  principal   only  classes  of  fixed-rate   mortgage-backed
securities   issued  by  the  U.S.   government   or  one  of  its  agencies  or
instrumentalities  will not be considered  illiquid if Mitchell  Hutchins or the
applicable   sub-adviser  has  determined  that  they  are  liquid  pursuant  to
guidelines established by the board. A fund may not be able to readily liquidate
its investments in illiquid securities and may have to sell other investments if
necessary to raise cash to meet its obligations.  The lack of a liquid secondary
market for illiquid securities may make it more difficult for a fund to assign a
value to those  securities for purposes of valuing its portfolio and calculating
its net asset value.

         Restricted  securities are not registered  under the Securities Act and
may be sold only in privately negotiated or other exempted transactions or after
a Securities Act registration statement has become effective. Where registration
is  required,  a fund may be  obligated  to pay all or part of the  registration
expenses and a  considerable  period may elapse between the time of the decision
to sell  and the  time a fund  may be  permitted  to sell a  security  under  an
effective  registration  statement.  If,  during such a period,  adverse  market
conditions  were to develop,  a fund might  obtain a less  favorable  price than
prevailed when it decided to sell.

         Not all restricted  securities are illiquid.  If a fund that may invest
outside the United States holds foreign  securities that are freely tradeable in
the  country  in which  they are  principally  traded,  they  generally  are not
considered  illiquid,  even if they are restricted in the United States. A large
institutional market has developed for many U.S. and foreign securities that are
not registered under the Securities Act. Institutional  investors generally will
not seek to sell these instruments to the general public, but instead will often
depend either on an efficient  institutional  market in which such  unregistered
securities can be readily resold or on an issuer's ability to honor a demand for
repayment.  Therefore, the fact that there are contractual or legal restrictions
on resale to the general public or certain  institutions  is not  dispositive of
the liquidity of such investments.

         Institutional  markets for restricted securities also have developed as
a result of Rule 144A,  which  establishes a "safe harbor" from the registration
requirements  of the  Securities  Act  for  resales  of  certain  securities  to
qualified  institutional  buyers. Such markets include automated systems for the
trading,  clearance and  settlement of  unregistered  securities of domestic and
foreign issuers, such as the PORTAL System sponsored by the National Association
of Securities Dealers,  Inc. An insufficient  number of qualified  institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
a fund, however, could affect adversely the marketability of the securities, and
the fund might be unable to dispose of them promptly or at favorable prices.

         The  board   has   delegated   the   function   of  making   day-to-day
determinations of liquidity to Mitchell  Hutchins or the applicable  sub-adviser
pursuant  to  guidelines  approved  by  the  board.  Mitchell  Hutchins  or  the
sub-adviser  takes  into  account  a number of  factors  in  reaching  liquidity
decisions,  including  (1) the  frequency  of trades for the  security,  (2) the
number of dealers that make quotes for the  security,  (3) the number of dealers

                                       26
<PAGE>

that have  undertaken to make a market in the security,  (4) the number of other
potential  purchasers  and (5) the  nature of the  security  and how  trading is
effected (e.g., the time needed to sell the security, how bids are solicited and
the mechanics of transfer).  Mitchell  Hutchins or the sub-adviser  monitors the
liquidity  of  restricted  securities  in  each  fund's  portfolio  and  reports
periodically on such decisions to the board.

         Mitchell Hutchins and (where  applicable) the sub-adviser  monitor each
fund's overall holdings of illiquid securities. If a fund's holdings of illiquid
securities exceeds its limitation on investments in illiquid  securities for any
reason (such as a particular  security  becoming  illiquid,  changes in relative
market  values  of liquid  and  illiquid  portfolio  securities  or  shareholder
redemptions),  Mitchell  Hutchins and the sub-adviser  will consider what action
would be in the best interest of the fund and its shareholders.  Such action may
include  engaging in an orderly  disposition  of securities to reduce the fund's
holdings of illiquid securities.  However, a fund is not required immediately to
dispose of illiquid securities under these circumstances,  and Mitchell Hutchins
or the applicable sub-adviser,  with the concurrence of the board, may determine
that it is in the best interests of the fund and its shareholders to continue to
hold the illiquid securities.

         REPURCHASE AGREEMENTS.  Repurchase agreements are transactions in which
a fund  purchases  securities  or other  obligations  from a bank or  securities
dealer (or its  affiliate)  and  simultaneously  commits  to resell  them to the
counterparty at an agreed-upon  date or upon demand and at a price  reflecting a
market  rate  of  interest  unrelated  to the  coupon  rate or  maturity  of the
purchased  obligations.  A fund maintains custody of the underlying  obligations
prior to their  repurchase,  either  through its regular  custodian or through a
special "tri-party"  custodian or sub-custodian that maintains separate accounts
for both the fund and its counterparty. Thus, the obligation of the counterparty
to pay the repurchase  price on the date agreed to or upon demand is, in effect,
secured by such obligations.

         Repurchase  agreements  carry certain risks not associated  with direct
investments in securities,  including a possible  decline in the market value of
the  underlying  obligations.  If their value  becomes less than the  repurchase
price,  plus any agreed-upon  additional  amount,  the counterparty must provide
additional  collateral so that at all times the  collateral is at least equal to
the repurchase  price plus any  agreed-upon  additional  amount.  The difference
between the total amount to be received upon  repurchase of the  obligations and
the price that was paid by a fund upon  acquisition  is accrued as interest  and
included  in  its  net  investment  income.   Repurchase   agreements  involving
obligations other than U.S. government  securities (such as commercial paper and
corporate bonds) may be subject to special risks and may not have the benefit of
certain protections in the event of the counterparty's insolvency. If the seller
or guarantor becomes insolvent,  the fund may suffer delays,  costs and possible
losses in connection  with the  disposition of collateral.  Each fund intends to
enter  into  repurchase  agreements  only with  counterparties  in  transactions
believed by Mitchell  Hutchins or the applicable  sub-adviser to present minimum
credit risks.

         REVERSE REPURCHASE  AGREEMENTS.  Reverse repurchase  agreements involve
the sale of securities held by a fund subject to its agreement to repurchase the
securities  at an  agreed-upon  date or upon demand and at a price  reflecting a
market  rate of  interest.  Reverse  repurchase  agreements  are subject to each
fund's  limitation  on  borrowings  and may be  entered  into only with banks or
securities dealers or their affiliates.  While a reverse repurchase agreement is
outstanding,  a fund will maintain,  in a segregated account with its custodian,
cash or liquid  securities,  marked to market daily, in an amount at least equal
to its  obligations  under the  reverse  repurchase  agreement.  See "The Funds'
Investments, Related Risks and Limitations -- Segregated Accounts."

         Reverse  repurchase  agreements  involve the risk that the buyer of the
securities  sold by a fund might be unable to deliver  them when that fund seeks
to repurchase.  If the buyer of securities under a reverse repurchase  agreement
files for bankruptcy or becomes insolvent,  the buyer or trustee or receiver may
receive  an  extension  of time to  determine  whether to  enforce  that  fund's
obligation to repurchase the  securities,  and the fund's use of the proceeds of
the reverse  repurchase  agreement may  effectively  be restricted  pending such
decision.

         WHEN-ISSUED  AND DELAYED  DELIVERY  SECURITIES.  Each fund may purchase
securities  on a  "when-issued"  basis or may  purchase or sell  securities  for
delayed  delivery,  i.e.,  for  issuance  or delivery to the fund later than the
normal  settlement  date at a stated  price and yield.  When  issued  securities
include  TBA  ("to  be  announced")  securities.   TBA  securities  are  usually
mortgage-backed securities that are purchased on a forward commitment basis with
an  approximate  principal  amount  and no  defined  maturity  date.  The actual
principal  amount and maturity  date are  determined  upon  settlement  when the
specific  mortgage pools are assigned.  A fund generally  would not pay for such


                                    27
<PAGE>

securities or start earning  interest on them until they are received.  However,
when  a fund  undertakes  a  when-issued  or  delayed  delivery  obligation,  it
immediately  assumes  the  risks  of  ownership,  including  the  risks of price
fluctuation.  Failure of the issuer to deliver a security purchased by a fund on
a when-issued or delayed  delivery  basis may result in the fund's  incurring or
missing an opportunity to make an alternative investment.

         A security  purchased on a  when-issued  or delayed  delivery  basis is
recorded as an asset on the commitment  date and is subject to changes in market
value,  generally  based upon  changes  in the level of  interest  rates.  Thus,
fluctuation  in the value of the security from the time of the  commitment  date
will affect a fund's net asset value. When a fund commits to purchase securities
on a when-issued or delayed delivery basis, its custodian  segregates  assets to
cover the amount of the commitment.  See "The Funds' Investments,  Related Risks
and   Limitations   --   Segregated   Accounts."   A  fund's   when-issued   and
delayed-delivery  purchase commitments could cause its net asset value per share
to be more volatile.  A fund may sell the right to acquire the security prior to
delivery  if  Mitchell   Hutchins  or  the  applicable   sub-adviser   deems  it
advantageous to do so, which may result in a gain or loss to the fund.

         DOLLAR  ROLLS.  In a dollar roll, a fund sells TBA  mortgage-backed  or
other  securities  for  delivery on the next regular  settlement  date for those
securities  and,  simultaneously,  contracts to purchase  substantially  similar
securities  for  delivery  on a later  settlement  date.  Dollar  rolls also are
subject to a fund's limitation on borrowings.

         DURATION.  Duration  is a measure of the  expected  life of a bond on a
present value basis.  Duration  incorporates  the bond's yield,  coupon interest
payments,  final  maturity and call  features into one measure and is one of the
fundamental  tools used by Mitchell  Hutchins or the  applicable  sub-adviser in
portfolio  selection and yield curve  positioning of a fund's bond  investments.
Duration was  developed as a more precise  alternative  to the concept  "term to
maturity."  Traditionally,  a bond's "term to maturity" has been used as a proxy
for the  sensitivity  of the bond's price to changes in interest rates (which is
the  "interest  rate  risk" or  "volatility"  of the  bond).  However,  "term to
maturity"  measures only the time until the scheduled final payment on the bond,
taking no account of the pattern of payments prior to maturity.

         Duration  takes the length of the time  intervals  between  the present
time and the time that the interest and principal  payments are scheduled or, in
the case of a  callable  bond,  expected  to be made,  and  weights  them by the
present  values of the cash to be received at each future point in time. For any
bond  with  interest  payments  occurring  prior to the  payment  of  principal,
duration is always less than maturity. For example,  depending on its coupon and
the level of market  yields,  a Treasury note with a remaining  maturity of five
years  might  have a  duration  of 4.5  years.  For  mortgage-backed  and  other
securities that are subject to  prepayments,  put or call features or adjustable
coupons,  the difference  between the remaining stated maturity and the duration
is likely to be much greater.

         Duration allows Mitchell Hutchins or the applicable sub-adviser to make
certain predictions as to the effect that changes in the level of interest rates
will have on the value of a fund's  portfolio of bonds.  For  example,  when the
level of interest  rates  increases by 1%, a bond having a positive  duration of
three years  generally  will  decrease by  approximately  3%. Thus,  if Mitchell
Hutchins or a sub-adviser calculates the duration of a fund's portfolio of bonds
as three years,  it normally  would  expect the  portfolio to change in value by
approximately  3% for every 1% change in the level of interest  rates.  However,
various factors,  such as changes in anticipated  prepayment rates,  qualitative
considerations and market supply and demand, can cause particular  securities to
respond somewhat  differently to changes in interest rates than indicated in the
above  example.  Moreover,  in the case of  mortgage-backed  and  other  complex
securities,  duration  calculations  are estimates and are not precise.  This is
particularly  true during  periods of market  volatility.  Accordingly,  the net
asset  value of a fund's  portfolio  of bonds may vary in  relation  to interest
rates by a greater or lesser percentage than indicated by the above example.

         Futures,  options  and  options  on futures  have  durations  that,  in
general,  are closely  related to the duration of the  securities  that underlie
them.  Holding long futures or call option  positions  will  lengthen  portfolio
duration by approximately  the same amount as would holding an equivalent amount
of the  underlying  securities.  Short  futures or put  options  have  durations
roughly equal to the negative  duration of the  securities  that underlie  these
positions,  and have the effect of reducing  portfolio duration by approximately
the  same  amount  as would  selling  an  equivalent  amount  of the  underlying
securities.

                                       28

         There are some  situations in which the standard  duration  calculation
does not properly  reflect the interest  rate  exposure of a bond.  For example,
floating  and  variable  rate bonds often have final  maturities  of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon reset.  Another  example where the interest rate exposure is not properly
captured by the standard  duration  calculation  is the case of  mortgage-backed
securities.  The stated final maturity of such securities is generally 30 years,
but  current  prepayment  rates are  critical  in  determining  the  securities'
interest rate exposure. In these and other similar situations, Mitchell Hutchins
or the applicable sub-adviser will use more sophisticated  analytical techniques
that  incorporate the economic life of a security into the  determination of its
duration and, therefore, its interest rate exposure.

         LENDING OF PORTFOLIO  SECURITIES.  Each fund is  authorized to lend its
portfolio to  broker-dealers  or institutional  investors that Mitchell Hutchins
deems qualified.  Lending  securities  enables a fund to earn additional income,
but could result in a loss or delay in recovering these securities. The borrower
of a fund's portfolio  securities must maintain  acceptable  collateral with the
fund's  custodian in an amount,  marked to market  daily,  at least equal to the
market value of the  securities  loaned,  plus accrued  interest and  dividends.
Acceptable  collateral  is  limited  to cash,  U.S.  government  securities  and
irrevocable  letters  of credit  that meet  certain  guidelines  established  by
Mitchell  Hutchins.  Each fund may reinvest any cash  collateral in money market
investments or other short-term  liquid  investments  including other investment
companies.  A fund also may  reinvest  cash  collateral  in  private  investment
vehicles  similar to money  market  funds,  including  one  managed by  Mitchell
Hutchins.   In   determining   whether  to  lend   securities  to  a  particular
broker-dealer or institutional  investor,  Mitchell Hutchins will consider,  and
during  the  period  of  the  loan  will   monitor,   all  relevant   facts  and
circumstances,  including the  creditworthiness of the borrower.  Each fund will
retain  authority to terminate  any of its loans at any time.  Each fund may pay
reasonable  fees in  connection  with a loan and may pay the borrower or placing
broker a negotiated  portion of the interest earned on the  reinvestment of cash
held as  collateral.  A fund will receive  amounts  equivalent to any dividends,
interest or other  distributions on the securities loaned. Each fund will regain
record ownership of loaned  securities to exercise  beneficial  rights,  such as
voting and subscription  rights,  when regaining such rights is considered to be
in the fund's interest.

         Pursuant  to  procedures  adopted by the board  governing  each  fund's
securities  lending  program,  PaineWebber has been retained to serve as lending
agent for each  fund.  The  boards  also have  authorized  the  payment  of fees
(including  fees  calculated  as a percentage of invested  cash  collateral)  to
PaineWebber for these services.  Each board  periodically  reviews all portfolio
securities  loan  transactions  for which  PaineWebber  acted as lending  agent.
PaineWebber  also has been approved as a borrower  under each fund's  securities
lending program.

         SHORT  SALES  "AGAINST  THE BOX." Each fund  (other  than Money  Market
Portfolio)  may engage in short sales of  securities it owns or has the right to
acquire at no added cost through  conversion or exchange of other  securities it
owns (short sales  "against the box").  To make  delivery to the  purchaser in a
short sale,  the executing  broker  borrows the  securities  being sold short on
behalf of a fund, and that fund is obligated to replace the securities  borrowed
at a date in the  future.  When a fund  sells  short,  it  establishes  a margin
account with the broker  effecting the short sale and deposits  collateral  with
the broker. In addition,  the fund maintains,  in a segregated  account with its
custodian,  the securities that could be used to cover the short sale. Each fund
incurs  transaction  costs,  including  interest  expense,  in  connection  with
opening, maintaining and closing short sales "against the box."

         A fund  might  make a short  sale  "against  the box" to hedge  against
market risks when Mitchell Hutchins or a sub-adviser  believes that the price of
a security  may  decline,  thereby  causing a decline in the value of a security
owned by the fund or a security  convertible into or exchangeable for a security
owned by the fund. In such case,  any loss in the fund's long position after the
short  sale  should be reduced by a  corresponding  gain in the short  position.
Conversely, any gain in the long position after the short sale should be reduced
by a  corresponding  loss in the short  position.  The extent to which  gains or
losses in the long  position  are  reduced  will  depend  upon the amount of the
securities  sold short  relative  to the amount of the  securities  a fund owns,
either directly or indirectly,  and in the case where the fund owns  convertible
securities,  changes in the  investment  values or  conversion  premiums of such
securities.

         SEGREGATED ACCOUNTS.  When a fund enters into certain transactions that
involve  obligations  to make future  payments to third  parties,  including the
purchase of securities on a when-issued or delayed  delivery basis,  and reverse

                                       29
<PAGE>

repurchase  agreements,  it  will  maintain  with  an  approved  custodian  in a
segregated  account cash or liquid  securities,  marked to market  daily,  in an
amount  at  least  equal to the  fund's  obligation  or  commitment  under  such
transactions.   As   described   below  under   "Strategies   Using   Derivative
Instruments,"  segregated  accounts  may also be  required  in  connection  with
certain  transactions  involving options,  futures or forward currency contracts
and swaps.

INVESTMENT LIMITATIONS OF THE FUNDS

         FUNDAMENTAL   LIMITATIONS.   The   following   fundamental   investment
limitations  cannot be changed for a fund  without the  affirmative  vote of the
lesser of (a) more than 50% of the outstanding  shares of the fund or (b) 67% or
more of the shares of the fund present at a  shareholders'  meeting if more than
50% of the  outstanding  shares are  represented  at the meeting in person or by
proxy. If a percentage restriction is adhered to at the time of an investment or
transaction,  later changes in percentage  resulting  from a change in values of
portfolio  securities  or  amount  of  total  assets  will not be  considered  a
violation of any of the  following  limitations.  With regard to the  borrowings
limitation  in  fundamental  limitation  (2),  each  fund will  comply  with the
applicable restrictions of Section 18 of the Investment Company Act.

         Each fund will not:

(1) purchase any security if, as a result of that  purchase,  25% or more of the
fund's  total  assets would be invested in  securities  of issuers  having their
principal business activities in the same industry,  except that this limitation
does not apply to securities  issued or guaranteed by the U.S.  government,  its
agencies or  instrumentalities  or to municipal  securities  (or, in the case of
Money Market Portfolio,  to certificates of deposit and bankers'  acceptances of
domestic branches of U.S. banks).

For Money Market Portfolio only the following  interpretations apply to, but are
not  a  part  of,  this  fundamental  restriction:  (a)  with  respect  to  this
limitation,  domestic  and foreign  banking will be  considered  to be different
industries and (b)  asset-backed  securities will be grouped in industries based
upon their underlying assets and not treated as constituting a single,  separate
industry.

(2) issue senior  securities  or borrow  money,  except as  permitted  under the
Investment  Company  Act and then not in excess of 33 1/3% of the  fund's  total
assets  (including the amount of the senior securities issued but reduced by any
liabilities not constituting  senior  securities) at the time of the issuance or
borrowing,  except that the fund may borrow up to an  additional 5% of its total
assets (not including the amount borrowed) for temporary or emergency purposes.

(3)  make  loans,  except  through  loans of  portfolio  securities  or  through
repurchase  agreements,  provided  that for  purposes of this  restriction,  the
acquisition of bonds, debentures,  other bonds or instruments, or participations
or other interests therein and investments in government obligations, commercial
paper, certificates of deposit, bankers' acceptances or similar instruments will
not be considered the making of a loan.

The following  interpretation  applies to, but is not part of, this  fundamental
restriction:  A fund's investments in master notes and similar  instruments will
not be considered to be the making of a loan.

(4) engage in the business of underwriting  securities of other issuers,  except
to the extent that the fund might be considered an underwriter under the federal
securities laws in connection with its disposition of portfolio securities.

(5) purchase or sell real  estate,  except that  investments  in  securities  of
issuers  that  invest  in  real  estate  and   investments  in   mortgage-backed
securities,  mortgage participations or other instruments supported by interests
in real estate are not subject to this limitation,  and except that the fund may
exercise  rights under  agreements  relating to such  securities,  including the
right to enforce  security  interests and to hold real estate acquired by reason
of such  enforcement  until  that real  estate can be  liquidated  in an orderly
manner.

(6) purchase or sell physical  commodities unless acquired as a result of owning
securities or other instruments,  but the fund may purchase,  sell or enter into
financial  options  and  futures,  forward  and spot  currency  contracts,  swap
transactions and other financial contracts or derivative instruments.

                                       30
<PAGE>

The following  investment  restriction applies to all funds except Global Income
Portfolio and Strategic Income Portfolio:

(7) purchase  securities of any one issuer if, as a result,  more than 5% of the
fund's total assets would be invested in  securities  of that issuer or the fund
would own or hold more than 10% of the  outstanding  voting  securities  of that
issuer, except that up to 25% of the fund's total assets may be invested without
regard to this  limitation,  and except that this  limitation  does not apply to
securities  issued  or  guaranteed  by the U.S.  government,  its  agencies  and
instrumentalities or to securities issued by other investment companies.

         The  following  interpretation  applies  to, but is not a part of, this
fundamental  restriction:  Mortgage-  and  asset-backed  securities  will not be
considered  to have been issued by the same  issuer by reason of the  securities
having the same sponsor,  and mortgage- and asset-backed  securities issued by a
finance or other  special  purpose  subsidiary  that are not  guaranteed  by the
parent  company will be  considered  to be issued by a separate  issuer from the
parent company.

         NON-FUNDAMENTAL  LIMITATIONS. The following investment restrictions are
non-fundamental  and may be changed by the vote of the board without shareholder
approval. If a percentage restriction is adhered to at the time of an investment
or transaction, later changes in percentage resulting from a change in values of
portfolio  securities  or  amount  of  total  assets  will not be  considered  a
violation of any of the following limitations.

         Each fund will not:

(1) hold assets of any issuers, at the end of any calendar quarter (or within 30
days  thereafter),  to the extent those holdings would cause the fund to fail to
satisfy  the  diversification  requirements  imposed  by  section  817(h) of the
Internal  Revenue  Code  and  the  Treasury  regulations  issued  thereunder  on
segregated  asset accounts used to fund variable  annuity  and/or  variable life
insurance  contracts  (which  requirements  must be satisfied by the fund as the
investment vehicle underlying those accounts);

(2) purchase portfolio  securities while borrowings in excess of 5% of its total
assets are outstanding;

(3) purchase  securities on margin,  except for short-term  credit necessary for
clearance  of  portfolio  transactions  and except that the fund may make margin
deposits in connection  with its use of financial  options and futures,  forward
and spot currency contracts,  swap transactions and other financial contracts or
derivative instruments;

(4) engage in short sales of  securities  or maintain a short  position,  except
that the  fund  may (a) sell  short  "against  the box" and (b)  maintain  short
positions in connection with its use of financial  options and futures,  forward
and spot currency contracts,  swap transactions and other financial contracts or
derivative instruments; or

(5) purchase  securities  of other  investment  companies,  except to the extent
permitted by the Investment Company Act and except that this limitation does not
apply to  securities  received  or  acquired  as  dividends,  through  offers of
exchange, or as a result of reorganization, consolidation, or merger.

                     STRATEGIES USING DERIVATIVE INSTRUMENTS

         GENERAL  DESCRIPTION  OF DERIVATIVE  INSTRUMENTS.  Each fund other than
Money Market  Portfolio is authorized to use a variety of financial  instruments
("Derivative   Instruments"),   including  certain  options,  futures  contracts
(sometimes  referred to as "futures"),  options on futures  contracts and swaps.
For funds that are  permitted  to invest  outside  the United  States,  Mitchell
Hutchins or the sub-adviser  also may use forward  currency  contracts,  foreign
currency options and futures and options on foreign currency futures. A fund may
enter into  transactions  involving one or more types of Derivative  Instruments
under  which  the  full  value  of  its  portfolio  is  at  risk.  Under  normal
circumstances,  however, each fund's use of these instruments will place at risk
a much  smaller  portion of its assets.  In  particular,  each fund except Money
Market Portfolio may use the Derivative Instruments described below.

                                       31
<PAGE>

         A fund might not use any  derivative  instruments  or  strategies,  and
there can be no assurance  that using any  strategy  will  succeed.  If Mitchell
Hutchins or a sub-adviser, as applicable, is incorrect in its judgment on market
values,  interest  rates  or  other  economic  factors  in  using  a  derivative
instrument  or strategy,  a fund may have lower net income and a net loss on the
investment.

         OPTIONS ON  SECURITIES  AND  FOREIGN  CURRENCIES  -- A call option is a
short-term contract pursuant to which the purchaser of the option, in return for
a premium,  has the right to buy the security or currency  underlying the option
at a specified  price at any time during the term of the option or at  specified
times or at the  expiration  of the  option,  depending  on the  type of  option
involved.  The writer of the call option,  who  receives  the  premium,  has the
obligation,  upon  exercise of the option during the option term, to deliver the
underlying  security or currency  against  payment of the exercise  price. A put
option is a similar contract that gives its purchaser,  in return for a premium,
the right to sell the  underlying  security or  currency  at a  specified  price
during the option term or at specified times or at the expiration of the option,
depending  on the type of option  involved.  The writer of the put  option,  who
receives the premium, has the obligation, upon exercise of the option during the
option term, to buy the underlying security or currency at the exercise price.

         OPTIONS ON SECURITIES  INDICES -- A securities  index assigns  relative
values to the securities  included in the index and  fluctuates  with changes in
the market values of those securities. A securities index option operates in the
same way as a more  traditional  securities  option,  except that  exercise of a
securities  index  option is  effected  with cash  payment  and does not involve
delivery of securities.  Thus, upon exercise of a securities  index option,  the
purchaser  will  realize,  and the  writer  will  pay,  an  amount  based on the
difference  between the exercise  price and the closing price of the  securities
index.

         SECURITIES  INDEX  FUTURES  CONTRACTS  -- A  securities  index  futures
contract is a bilateral  agreement pursuant to which one party agrees to accept,
and the other  party  agrees to make,  delivery  of an amount of cash equal to a
specified dollar amount times the difference  between the securities index value
at the close of  trading  of the  contract  and the  price at which the  futures
contract is originally struck. No physical delivery of the securities comprising
the index is made.  Generally,  contracts are closed out prior to the expiration
date of the contract.

         INTEREST RATE AND FOREIGN CURRENCY  FUTURES  CONTRACTS -- Interest rate
and foreign  currency  futures  contracts are bilateral  agreements  pursuant to
which one party agrees to make,  and the other party agrees to accept,  delivery
of a specified type of debt security or currency at a specified  future time and
at a specified  price.  Although such futures  contracts by their terms call for
actual delivery or acceptance of bonds or currency,  in most cases the contracts
are  closed  out  before the  settlement  date  without  the making or taking of
delivery.

         OPTIONS ON FUTURES  CONTRACTS  --  Options  on  futures  contracts  are
similar to options on securities or currency, except that an option on a futures
contract gives the purchaser the right,  in return for the premium,  to assume a
position in a futures  contract  (a long  position if the option is a call and a
short  position  if the  option is a put),  rather  than to  purchase  or sell a
security or currency, at a specified price at any time during the option term or
at specified times or at the expiration of the option,  depending on the type of
option  involved.  Upon  exercise  of the  option,  the  delivery of the futures
position  to the holder of the option  will be  accompanied  by  delivery of the
accumulated  balance that represents the amount by which the market price of the
futures contract exceeds, in the case of a call, or is less than, in the case of
a put, the exercise price of the option on the future.  The writer of an option,
upon  exercise,  will  assume a short  position in the case of a call and a long
position in the case of a put.

         FORWARD CURRENCY  CONTRACTS -- A forward currency  contract involves an
obligation to purchase or sell a specific  currency at a specified  future date,
which may be any fixed number of days from the contract  date agreed upon by the
parties, at a price set at the time the contract is entered into.

         GENERAL DESCRIPTION OF STRATEGIES USING DERIVATIVE INSTRUMENTS.  A fund
may use  Derivative  Instruments  to attempt to hedge its  portfolio and also to
attempt to enhance  income or return or realize gains and to manage the duration
of its  bond  portfolio.  A fund  may use  Derivative  Instruments  to  maintain
exposure to stocks or bonds while maintaining a cash balance for fund management
purposes (such as to provide liquidity to meet anticipated  shareholder sales of
fund shares and for fund operating expenses), to facilitate trading or to adjust
its exposure to different asset classes.  For example,  Global Equity  Portfolio
may use Derivative Instruments to adjust its exposure to U.S. and foreign equity
markets in connection with a reallocation or rebalancing of the fund's assets. A

                                       32
<PAGE>

fund  that  may  invest  outside  the  United  States  also  may use  Derivative
Instruments  on  currencies,  including  forward  currency  contracts,  to hedge
against  price  changes of  securities  that the fund owns or intends to acquire
that are  attributable  to changes in the value of the  currencies  in which the
securities  are  denominated.  A fund  may also use  Derivative  Instruments  on
currencies  to shift  exposure  from one  currency  to  another or to attempt to
realize gains from favorable changes in exchange rates.

         Hedging  strategies  can be broadly  categorized  as "short hedges" and
"long  hedges." A short hedge is a purchase or sale of a  Derivative  Instrument
intended  partially or fully to offset potential declines in the value of one or
more investments held in a fund's portfolio. Thus, in a short hedge a fund takes
a position  in a  Derivative  Instrument  whose price is expected to move in the
opposite  direction of the price of the investment being hedged.  For example, a
fund might  purchase a put option on a  security  to hedge  against a  potential
decline in the value of that  security.  If the price of the  security  declined
below the  exercise  price of the put,  a fund could  exercise  the put and thus
limit its loss below the  exercise  price to the premium  paid plus  transaction
costs. In the  alternative,  because the value of the put option can be expected
to increase as the value of the underlying  security  declines,  a fund might be
able to close out the put option and realize a gain to offset the decline in the
value of the security.

         Conversely,  a  long  hedge  is a  purchase  or  sale  of a  Derivative
Instrument  intended  partially  or fully to offset  potential  increases in the
acquisition  cost of one or more  investments  that a fund  intends to  acquire.
Thus, in a long hedge, a fund takes a position in a Derivative  Instrument whose
price is expected to move in the same direction as the price of the  prospective
investment being hedged.  For example,  a fund might purchase a call option on a
security  it intends to  purchase  in order to hedge  against an increase in the
cost of the security.  If the price of the security increased above the exercise
price of the call, a fund could exercise the call and thus limit its acquisition
cost to the  exercise  price  plus  the  premium  paid and  transactions  costs.
Alternatively,  a fund might be able to offset the price increase by closing out
an appreciated call option and realizing a gain.

         A fund may purchase and write (sell) straddles on securities or indices
of  securities.  A long  straddle  is a  combination  of a call and a put option
purchased  on the same  security  or on the same  futures  contract,  where  the
exercise  price of the put is equal to the  exercise  price of the call.  A fund
might  enter  into a long  straddle  when  Mitchell  Hutchins  or a  sub-adviser
believes  it likely  that the  prices of the  securities  will be more  volatile
during the term of the option than the option pricing implies.  A short straddle
is a  combination  of a call and a put  written on the same  security  where the
exercise  price of the put is equal to the  exercise  price of the call.  A fund
might  enter into a short  straddle  when  Mitchell  Hutchins  or a  sub-adviser
believes  it  unlikely  that the prices of the  securities  will be as  volatile
during the term of the option as the option pricing implies.

         Derivative  Instruments on securities or currencies  generally are used
to hedge against price movements in one or more particular  securities positions
that a fund owns or intends to acquire. Derivative Instruments on stock indices,
in contrast, generally are used to hedge against price movements in broad equity
market  sectors in which a fund has  invested  or expects to invest.  Derivative
Instruments on bonds may be used to hedge either individual  securities or broad
fixed income market sectors.

         Income strategies using Derivative  Instruments may include the writing
of  covered  options  to obtain  the  related  option  premiums.  Return or gain
strategies  may include using  Derivative  Instruments to increase or decrease a
fund's  exposure  to  different  asset  classes  without  buying or selling  the
underlying  instruments.  A fund  also  may use  derivatives  to  simulate  full
investment  by the fund while  maintaining  a cash  balance for fund  management
purposes (such as to provide liquidity to meet anticipated  shareholder sales of
fund shares and for fund operating expenses).

         The use of Derivative  Instruments is subject to applicable regulations
of the SEC, the several options and futures exchanges upon which they are traded
and the Commodity Futures Trading  Commission  ("CFTC").  In addition,  a fund's
ability to use Derivative Instruments may be limited by tax considerations.  See
"Taxes."

         In addition to the products,  strategies and risks  described below and
in  the  Prospectus,   Mitchell  Hutchins  and  the  sub-advisers  may  discover
additional  opportunities  in connection  with  Derivative  Instruments and with
hedging, income, return and gain strategies.  These new opportunities may become
available as regulatory  authorities broaden the range of permitted transactions

                                       33
<PAGE>

and as  new  Derivative  Instruments  and  techniques  are  developed.  Mitchell
Hutchins or the applicable sub-adviser may use these opportunities for a fund to
the extent that they are  consistent  with the fund's  investment  objective and
permitted by its investment  limitations and applicable regulatory  authorities.
The  Prospectus or SAI will be  supplemented  to the extent that new products or
techniques involve  materially  different risks than those described below or in
the Prospectus.

         SPECIAL RISKS OF STRATEGIES  USING DERIVATIVE  INSTRUMENTS.  The use of
Derivative  Instruments involves special  considerations and risks, as described
below.  Risks pertaining to particular  Derivative  Instruments are described in
the sections that follow.

(1) Successful use of most  Derivative  Instruments  depends upon the ability of
Mitchell  Hutchins or the  applicable  sub-adviser  to predict  movements of the
overall securities,  interest rate or currency exchange markets,  which requires
different skills than predicting changes in the prices of individual securities.
While  Mitchell  Hutchins and the  sub-advisers  are  experienced  in the use of
Derivative  Instruments,  there can be no assurance that any particular strategy
adopted will succeed.

(2) There might be imperfect correlation, or even no correlation,  between price
movements of a Derivative Instrument and price movements of the investments that
are being hedged. For example, if the value of a Derivative Instrument used in a
short  hedge  increased  by  less  than  the  decline  in  value  of the  hedged
investment, the hedge would not be fully successful.  Such a lack of correlation
might occur due to factors affecting the markets in which Derivative Instruments
are  traded,  rather  than  the  value  of the  investments  being  hedged.  The
effectiveness of hedges using  Derivative  Instruments on indices will depend on
the  degree  of  correlation  between  price  movements  in the  index and price
movements in the securities being hedged.

(3)  Hedging  strategies,  if  successful,  can reduce risk of loss by wholly or
partially  offsetting the negative effect of unfavorable  price movements in the
investments  being  hedged.   However,   hedging   strategies  can  also  reduce
opportunity  for gain by  offsetting  the  positive  effect of  favorable  price
movements in the hedged investments. For example, if a fund entered into a short
hedge  because  Mitchell  Hutchins or a  sub-adviser  projected a decline in the
price of a security in that  fund's  portfolio,  and the price of that  security
increased  instead,  the gain from that  increase  might be wholly or  partially
offset by a decline in the price of the Derivative Instrument.  Moreover, if the
price of the  Derivative  Instrument  declined by more than the  increase in the
price of the security,  the fund could suffer a loss.  In either such case,  the
fund would have been in a better position had it not hedged at all.

(4) As described  below, a fund might be required to maintain assets as "cover,"
maintain  segregated accounts or make margin payments when it takes positions in
Derivative Instruments involving obligations to third parties (i.e.,  Derivative
Instruments other than purchased  options).  If the fund was unable to close out
its positions in those Derivative Instruments,  it might be required to continue
to maintain  such assets or accounts or make such  payments  until the positions
expired or matured.  These  requirements might impair a fund's ability to sell a
portfolio  security or make an investment  at a time when it would  otherwise be
favorable  to do so, or require  that the fund sell a  portfolio  security  at a
disadvantageous  time. A fund's  ability to close out a position in a Derivative
Instrument  prior to expiration or maturity depends on the existence of a liquid
secondary  market  or,  in  the  absence  of  such a  market,  the  ability  and
willingness  of a  counterparty  to enter  into a  transaction  closing  out the
position.  Therefore,  there is no  assurance  that any hedging  position can be
closed out at a time and price that is favorable to a fund.

         COVER FOR STRATEGIES USING DERIVATIVE  INSTRUMENTS.  Transactions using
Derivative  Instruments,  other than purchased  options,  expose the funds to an
obligation to another  party.  A fund will not enter into any such  transactions
unless it owns either (1) an  offsetting  ("covered")  position  in  securities,
currencies  or  other  options  or  futures  contracts  or (2)  cash  or  liquid
securities,  with a  value  sufficient  at all  times  to  cover  its  potential
obligations  to the extent not covered as provided in (1) above.  Each fund will
comply with SEC guidelines  regarding cover for such  transactions  and will, if
the guidelines so require,  set aside cash or liquid  securities in a segregated
account with its custodian in the prescribed amount.

         Assets  used as cover or held in a  segregated  account  cannot be sold
while the position in the  corresponding  Derivative  Instrument is open, unless
they are replaced with similar assets.  As a result,  committing a large portion
of a fund's  assets to cover  positions or to segregated  accounts  could impede
portfolio  management or the fund's ability to meet redemption requests or other
current obligations.

         OPTIONS.  The funds may purchase put and call options, and write (sell)
covered  put or call  options on  securities  in which they  invest and  related
indices.  Funds that may invest  outside the United States also may purchase put
and call options and write covered options on foreign  currencies.  The purchase
of call  options may serve as a long hedge,  and the purchase of put options may
serve as a short hedge.  In addition,  a fund may also use options to attempt to
enhance  return or realize  gains by  increasing  or reducing its exposure to an
asset class without  purchasing or selling the  underlying  securities.  Writing
covered put or call options can enable a fund to enhance income by reason of the
premiums paid by the  purchasers of such options.  Writing  covered call options
serves as a limited  short  hedge,  because  declines in the value of the hedged
investment would be offset to the extent of the premium received for writing the
option. However, if the security appreciates to a price higher than the exercise
price of the call option,  it can be expected  that the option will be exercised
and the  affected  fund will be  obligated to sell the security at less than its
market value. Writing covered put options serves as a limited long hedge because
increases in the value of the hedged investment would be offset to the extent of
the  premium  received  for  writing  the  option.   However,  if  the  security
depreciates to a price lower than the exercise  price of the put option,  it can
be expected that the put option will be exercised and the fund will be obligated
to purchase the security at more than its market value.  The securities or other
assets  used as cover for  over-the-counter  options  written by a fund would be
considered  illiquid  to the  extent  described  under  "The  Funds'  Investment
Policies, Related Risks and Limitations--Illiquid Securities."

         The value of an option position will reflect,  among other things,  the
current market value of the  underlying  investment,  the time  remaining  until
expiration,  the  relationship  of the exercise price to the market price of the
underlying  investment,  the  historical  price  volatility  of  the  underlying
investment and general market conditions. Options normally have expiration dates
of up to nine  months.  Generally,  over-the-counter  debt  options  or  foreign
currency options used by the funds are European-style  options.  This means that
the option is only exercisable  immediately prior to its expiration.  This is in
contrast to  American-style  options which are  exercisable at any time prior to
the  expiration  date of the option.  There are also other types of options that
may be exercised on certain  specified  dates  before  expiration.  Options that
expire unexercised have no value.

         A fund may  effectively  terminate  its  right or  obligation  under an
option by entering into a closing transaction. For example, a fund may terminate
its  obligation  under a call or put option that it had written by purchasing an
identical call or put option;  this is known as a closing purchase  transaction.
Conversely,  a fund may  terminate  a  position  in a put or call  option it had
purchased by writing an identical put or call option; this is known as a closing
sale transaction. Closing transactions permit a fund to realize profits or limit
losses on an option position prior to its exercise or expiration.

         The   funds  may   purchase   and  write   both   exchange-traded   and
over-the-counter  options.  Currently,  many  options on equity  securities  are
exchange-traded.  Exchange  markets for options on bonds and foreign  currencies
exist but are relatively new, and these  instruments are primarily traded on the
over-the-counter market. Exchange-traded options in the United States are issued
by a clearing  organization  affiliated with the exchange on which the option is
listed that, in effect,  guarantees completion of every  exchange-traded  option
transaction. In contrast,  over-the-counter options are contracts between a fund
and its  counterparty  (usually a securities  dealer or a bank) with no clearing
organization   guarantee.   Thus,   when  a  fund   purchases   or   writes   an
over-the-counter  option, it relies on the counterparty to make or take delivery
of the  underlying  investment  upon  exercise  of the  option.  Failure  by the
counterparty  to do so would  result in the loss of any premium paid by the fund
as well as the loss of any expected benefit of the transaction.

         The  funds'   ability  to   establish   and  close  out   positions  in
exchange-listed  options depends on the existence of a liquid market.  The funds
intend to purchase or write only those  exchange-traded  options for which there
appears to be a liquid secondary market. However, there can be no assurance that
such a market will exist at any particular  time.  Closing  transactions  can be
made  for  over-the-counter  options  only  by  negotiating  directly  with  the
counterparty,  or by a transaction  in the  secondary  market if any such market
exists.  Although the funds will enter into  over-the-counter  options only with
counterparties  that  are  expected  to be  capable  of  entering  into  closing
transactions  with the funds,  there is no assurance that a fund will in fact be
able to close out an over-the-counter option position at a favorable price prior
to expiration.  In the event of insolvency of the counterparty,  a fund might be
unable to close out an over-the-counter option position at any time prior to its
expiration.


                                       35
<PAGE>

         If a fund were unable to effect a closing  transaction for an option it
had purchased,  it would have to exercise the option to realize any profit.  The
inability to enter into a closing purchase transaction for a covered put or call
option written by the fund could cause material losses because the fund would be
unable to sell the  investment  used as cover for the written  option  until the
option expires or is exercised.

         A fund may  purchase  and write put and call options on indices in much
the same manner as the more  traditional  options  discussed  above,  except the
index options may serve as a hedge against overall  fluctuations in a securities
market (or market sector) rather than anticipated  increases or decreases in the
value of a particular security.

         LIMITATIONS  ON THE  USE OF  OPTIONS.  The  funds'  use of  options  is
governed by the following guidelines,  which can be changed by the board without
shareholder vote:

(1) A fund may purchase a put or call option,  including any straddle or spread,
only if the value of its premium, when aggregated with the premiums on all other
options held by the fund, does not exceed 5% of its total assets.

(2) The aggregate value of securities  underlying put options written by a fund,
determined  as of the date the put options are  written,  will not exceed 50% of
its net assets.

(3) The aggregate premiums paid on all options (including options on securities,
foreign  currencies  and  securities  indices and options on futures  contracts)
purchased  by a fund  that are held at any time will not  exceed  20% of its net
assets.

         FUTURES.  The funds may  purchase  and sell  securities  index  futures
contracts,   interest  rate  futures  contracts,  debt  security  index  futures
contracts and (for those funds that invest  outside the United  States)  foreign
currency futures contracts.  A fund may also purchase put and call options,  and
write covered put and call options, on futures in which it is allowed to invest.
The purchase of futures or call options  thereon can serve as a long hedge,  and
the sale of futures or the purchase of put options  thereon can serve as a short
hedge.  Writing covered call options on futures contracts can serve as a limited
short hedge, and writing covered put options on futures contracts can serve as a
limited long hedge,  using a strategy  similar to that used for writing  covered
options on  securities  or indices.  In  addition,  a fund may  purchase or sell
futures contracts or purchase options thereon to increase or reduce its exposure
to an asset class without purchasing or selling the underlying securities either
as a hedge or to enhance return or realize gains.

         Futures strategies also can be used to manage the average duration of a
fund's portfolio.  If Mitchell Hutchins or the applicable  sub-adviser wishes to
shorten the average duration of a fund's portfolio,  the fund may sell a futures
contract or a call  option  thereon,  or  purchase a put option on that  futures
contract. If Mitchell Hutchins or the sub-adviser wishes to lengthen the average
duration of the fund's portfolio,  the fund may buy a futures contract or a call
option thereon, or sell a put option thereon.

         A fund may also write put  options on  futures  contracts  while at the
same  time  purchasing  call  options  on the same  futures  contracts  in order
synthetically  to create a long futures  contract  position.  Such options would
have the same strike  prices and  expiration  dates.  A fund will engage in this
strategy  only when it is more  advantageous  to a fund than is  purchasing  the
futures contract.

         No price is paid upon entering into a futures contract. Instead, at the
inception  of a futures  contract a fund is required to deposit in a  segregated
account with its  custodian,  in the name of the futures broker through whom the
transaction was effected,  "initial margin"  consisting of cash,  obligations of
the United States or obligations  fully  guaranteed as to principal and interest
by the  United  States,  in an  amount  generally  equal  to 10% or  less of the
contract  value.  Margin must also be deposited  when writing a call option on a
futures contract, in accordance with applicable exchange rules. Unlike margin in
securities transactions,  initial margin on futures contracts does not represent
a borrowing,  but rather is in the nature of a  performance  bond or  good-faith
deposit that is returned to a fund at the  termination of the transaction if all
contractual obligations have been satisfied.  Under certain circumstances,  such
as periods of high volatility, a fund may be required by an exchange to increase

                                       36
<PAGE>

the level of its initial margin payment,  and initial margin  requirements might
be increased generally in the future by regulatory action.

         Subsequent "variation margin" payments are made to and from the futures
broker daily as the value of the futures  position  varies,  a process  known as
"marking to market."  Variation  margin does not involve  borrowing,  but rather
represents a daily  settlement of each fund's  obligations  to or from a futures
broker.  When a fund  purchases  an option on a future,  the  premium  paid plus
transaction costs is all that is at risk. In contrast,  when a fund purchases or
sells a futures contract or writes a call option thereon, it is subject to daily
variation  margin calls that could be  substantial in the event of adverse price
movements.  If a fund  has  insufficient  cash to meet  daily  variation  margin
requirements,  it might  need to sell  securities  at a time when such sales are
disadvantageous.

         Holders  and  writers of futures  positions  and options on futures can
enter into offsetting closing  transactions,  similar to closing transactions on
options, by selling or purchasing,  respectively, an instrument identical to the
instrument  held or written.  Positions in futures and options on futures may be
closed only on an exchange or board of trade that  provides a secondary  market.
The funds intend to enter into futures  transactions only on exchanges or boards
of trade where there appears to be a liquid secondary market. However, there can
be no  assurance  that such a market will exist for a  particular  contract at a
particular time.

         Under certain  circumstances,  futures  exchanges  may establish  daily
limits on the amount that the price of a future or related  option can vary from
the previous day's settlement price;  once that limit is reached,  no trades may
be made that day at a price  beyond the limit.  Daily price  limits do not limit
potential  losses  because  prices  could  move to the daily  limit for  several
consecutive days with little or no trading,  thereby  preventing  liquidation of
unfavorable positions.

         If a fund  were  unable  to  liquidate  a futures  or  related  options
position due to the absence of a liquid  secondary  market or the  imposition of
price limits,  it could incur  substantial  losses.  A fund would continue to be
subject to market risk with respect to the position. In addition,  except in the
case of purchased  options,  a fund would  continue to be required to make daily
variation  margin  payments and might be required to maintain the position being
hedged by the future or option or to maintain cash or securities in a segregated
account.

         Certain  characteristics  of the futures market might increase the risk
that movements in the prices of futures  contracts or related  options might not
correlate  perfectly  with  movements  in the  prices of the  investments  being
hedged. For example, all participants in the futures and related options markets
are subject to daily variation  margin calls and might be compelled to liquidate
futures or related  options  positions  whose prices are moving  unfavorably  to
avoid being subject to further calls.  These  liquidations  could increase price
volatility of the instruments and distort the normal price relationship  between
the futures or options and the investments being hedged.  Also,  because initial
margin deposit  requirements  in the futures market are less onerous than margin
requirements in the securities markets,  there might be increased  participation
by  speculators  in the futures  markets.  This  participation  also might cause
temporary price  distortions.  In addition,  activities of large traders in both
the futures and securities  markets involving  arbitrage,  "program trading" and
other investment strategies might result in temporary price distortions.

         LIMITATIONS  ON THE USE OF  FUTURES  AND  RELATED  OPTIONS.  The use of
futures and related options is governed by the following  guidelines,  which can
be changed by the board without shareholder vote:

(1) The aggregate  initial margin and premiums on futures  contracts and related
options  that are not for bona fide  hedging  purposes (as defined by the CFTC),
excluding the amount by which options are "in-the-money", may not exceed 5% of a
fund's net assets.

(2) The aggregate premiums paid on all options (including options on securities,
foreign  currencies  and  securities  indices and options on futures  contracts)
purchased  by a fund  that are held at any time will not  exceed  20% of its net
assets.

(3) The aggregate  margin deposits on all futures  contracts and options thereon
held at any time by a fund will not exceed 5% of its total assets.

         FOREIGN CURRENCY  HEDGING  STRATEGIES -- SPECIAL  CONSIDERATIONS.  Each
fund that may invest  outside  the United  States may use options and futures on
foreign  currencies,  as described  above, and forward  currency  contracts,  as
described  below,  to hedge  against  movements  in the  values  of the  foreign
currencies in which the fund's securities are denominated. These currency hedges
can  protect  against  price  movements  in a security a fund owns or intends to
acquire that are  attributable  to changes in the value of the currency in which
it is denominated. These hedges do not, however, protect against price movements
in the securities that are attributable to other causes.

         A fund might seek to hedge against changes in the value of a particular
currency when no Derivative  Instruments  on that currency are available or such
Derivative  Instruments are considered  expensive.  In such cases,  the fund may
hedge  against price  movements in that  currency by entering into  transactions
using Derivative Instruments on another currency or a basket of currencies,  the
value of which  Mitchell  Hutchins or the applicable  sub-adviser  believes will
have a  positive  correlation  to the value of the  currency  being  hedged.  In
addition, a fund may use forward currency contracts to shift exposure to foreign
currency  fluctuations from one country to another. For example, if a fund owned
securities  denominated  in a foreign  currency  and  Mitchell  Hutchins  or the
sub-adviser  believed that currency would decline relative to another  currency,
it might  enter into a forward  contract  to sell an  appropriate  amount of the
first foreign currency,  with payment to be made in the second foreign currency.
Transactions that use two foreign currencies are sometimes referred to as "cross
hedging." Use of a different foreign currency  magnifies the risk that movements
in the price of the Derivative  Instrument  will not correlate or will correlate
unfavorably with the foreign currency being hedged.

         The value of Derivative  Instruments on foreign  currencies  depends on
the  value of the  underlying  currency  relative  to the U.S.  dollar.  Because
foreign  currency  transactions  occurring in the interbank market might involve
substantially  larger amounts than those involved in the use of such  Derivative
Instruments,  a fund  could be  disadvantaged  by having to deal in the  odd-lot
market  (generally  consisting of  transactions of less than $1 million) for the
underlying  foreign  currencies at prices that are less favorable than for round
lots.

         There is no systematic  reporting of last sale  information for foreign
currencies or any  regulatory  requirement  that  quotations  available  through
dealers or other market sources be firm or revised on a timely basis.  Quotation
information  generally  is  representative  of very  large  transactions  in the
interbank  market and thus might not reflect  odd-lot  transactions  where rates
might be less favorable. The interbank market in foreign currencies is a global,
round-the-clock  market.  To the extent the U.S.  options or futures markets are
closed while the markets for the underlying currencies remain open,  significant
price and rate movements might take place in the underlying  markets that cannot
be reflected in the markets for the Derivative Instruments until they reopen.

         Settlement of Derivative Instruments involving foreign currencies might
be required to take place within the country  issuing the  underlying  currency.
Thus,  the funds might be required to accept or make delivery of the  underlying
foreign  currency in accordance with any U.S. or foreign  regulations  regarding
the maintenance of foreign banking  arrangements by U.S.  residents and might be
required  to pay any  fees,  taxes and  charges  associated  with such  delivery
assessed in the issuing country.

         FORWARD  CURRENCY  CONTRACTS.  Funds that may invest outside the United
States may enter into  forward  currency  contracts  to purchase or sell foreign
currencies for a fixed amount of U.S. dollars or another foreign currency.  Such
transactions  may serve as long  hedges -- for  example,  a fund may  purchase a
forward  currency  contract  to lock in the  U.S.  dollar  price  of a  security
denominated  in a foreign  currency  that the fund  intends to acquire.  Forward
currency contract  transactions may also serve as short hedges -- for example, a
fund may sell a forward currency  contract to lock in the U.S. dollar equivalent
of the proceeds from the anticipated sale of a security denominated in a foreign
currency.

         The cost to a fund of engaging  in forward  currency  contracts  varies
with factors such as the currency  involved,  the length of the contract  period
and the market  conditions then prevailing.  Because forward currency  contracts
are  usually  entered  into on a principal  basis,  no fees or  commissions  are
involved.  When a fund enters into a forward currency contract, it relies on the
counterparty to make or take delivery of the underlying currency at the maturity
of the contract.  Failure by the  counterparty to do so would result in the loss
of any expected benefit of the transaction.

                                       38
<PAGE>

         As is the case with  futures  contracts,  parties to  forward  currency
contracts can enter into  offsetting  closing  transactions,  similar to closing
transactions  on  futures,  by  entering  into an  instrument  identical  to the
instrument  purchased or sold, but in the opposite direction.  Secondary markets
generally  do not exist for  forward  currency  contracts,  with the result that
closing  transactions  generally can be made for forward currency contracts only
by negotiating  directly with the counterparty.  Thus, there can be no assurance
that a fund will in fact be able to close out a forward  currency  contract at a
favorable  price prior to maturity.  In addition,  in the event of insolvency of
the  counterparty,  a fund  might be  unable  to close  out a  forward  currency
contract at any time prior to maturity. In either event, the fund would continue
to be subject to market risk with respect to the position, and would continue to
be required to maintain a position in the securities or currencies  that are the
subject of the hedge or to maintain cash or securities in a segregated account.

         The precise matching of forward currency contract amounts and the value
of the securities  involved  generally will not be possible because the value of
such securities, measured in the foreign currency, will change after the foreign
currency contract has been  established.  Thus, a fund might need to purchase or
sell  foreign  currencies  in the spot (cash)  market to the extent such foreign
currencies  are not covered by forward  contracts.  The projection of short-term
currency market movements is extremely  difficult,  and the successful execution
of a short-term hedging strategy is highly uncertain.

         LIMITATIONS ON THE USE OF FORWARD CURRENCY  CONTRACTS.  A fund that may
invest  outside the United States may enter into forward  currency  contracts or
maintain a net exposure to such  contracts only if (1) the  consummation  of the
contracts  would not obligate the fund to deliver an amount of foreign  currency
in excess of the value of the position being hedged by such contracts or (2) the
fund  segregates  with its custodian cash or liquid  securities in an amount not
less than the value of its total  assets  committed to the  consummation  of the
contract and not covered as provided in (1) above, as marked to market daily.

         SWAP  TRANSACTIONS.  Swap transactions  include swaps, caps, floors and
collars relating to interest rates, currencies, securities or other instruments.
Interest  rate swaps  involve  an  agreement  between  two  parties to  exchange
payments that are based,  for example,  on variable and  fixed-rates of interest
and that are  calculated  on the basis of a specified  amount of principal  (the
"notional  principal amount") for a specified period of time.  Interest rate cap
and floor  transactions  involve an  agreement  between two parties in which the
first party agrees to make payments to the counterparty when a designated market
interest  rate  goes  above  (in the case of a cap) or  below  (in the case of a
floor) a  designated  level on  predetermined  dates or during a specified  time
period.  Interest  rate collar  transactions  involve an  agreement  between two
parties in which payments are made when a designated market interest rate either
goes above a designated  ceiling level or goes below a designated floor level on
predetermined  dates or during a specified time period.  Currency  swaps,  caps,
floors and collars are similar to interest rate swaps, caps, floors and collars,
but they are based on currency exchange rates rather than interest rates. Equity
swaps or other  swaps  relating  to  securities  or other  instruments  are also
similar, but they are based on changes in the value of the underlying securities
or  instruments.  For example,  an equity swap might  involve an exchange of the
value of a particular  security or securities index in a certain notional amount
for the value of another  security or index or for the value of interest on that
notional amount at a specified fixed or variable rate.

         A fund may enter into  interest  rate swap  transactions  to preserve a
return or spread on a particular  investment  or portion of its  portfolio or to
protect  against  any  increase  in  the  price  of  securities  it  anticipates
purchasing at a later date. A fund may use interest rate swaps, caps, floors and
collars as a hedge on either an asset-based or liability-based  basis, depending
on  whether  it is  hedging  its  assets  or  liabilities.  Interest  rate  swap
transactions  are  subject to risks  comparable  to those  described  above with
respect to other derivatives strategies.

         A fund will  usually  enter  into  interest  rate swaps on a net basis,
i.e.,  the two payment  streams are netted out, with a fund receiving or paying,
as the case may be, only the net amount of the two payments.  Because segregated
accounts  will be  established  with  respect  to these  transactions,  Mitchell
Hutchins and the  sub-advisers  (if applicable)  believe such obligations do not
constitute  senior  securities  and,  accordingly,  will not treat them as being
subject to a fund's  borrowing  restrictions.  The net amount of the excess,  if
any, of a fund's obligations over its entitlements with respect to each interest
rate swap will be accrued on a daily basis,  and appropriate  fund assets having
an  aggregate  net asset  value at least  equal to the  accrued  excess  will be
maintained  in  a  segregated   account  as  described   above  in  "The  Funds'
Investments,  Related Risks and  Limitations--Segregated  Accounts." A fund also

                                       39
<PAGE>

will establish and maintain such  segregated  accounts with respect to its total
obligations  under any swaps that are not  entered  into on a net basis and with
respect to any caps, floors and collars that are written by the fund.

         A fund will  enter  swap  transactions  only with  banks or  recognized
securities  dealers or their  affiliates  believed by  Mitchell  Hutchins or the
applicable  sub-adviser  to  present  minimal  credit  risk in  accordance  with
guidelines  established by the fund's board.  If there is a default by the other
party  to such a  transaction,  a fund  will  have  to  rely on its  contractual
remedies  (which may be  limited  by  bankruptcy,  insolvency  or similar  laws)
pursuant to the agreements related to the transaction.

                             OWNERSHIP OF SECURITIES

         The Trust was formed on November 21, 1986 as a business trust under the
laws of the Commonwealth of Massachusetts and has thirteen operating series. The
Trust is governed  by a board of  trustees,  which is  authorized  to  establish
additional  series  and to issue an  unlimited  number of  shares of  beneficial
interest of each  existing or future  series,  par value  $0.001 per share.  The
board oversees each fund's operations.

annually,  plus any additional amounts due for board or committee meetings. Each
chairman of the audit and contract review  committees of individual funds within
the  PaineWebber  fund complex  receives  additional  compensation,  aggregating
$15,000 annually,  from the relevant funds. All board members are reimbursed for
any  expenses  incurred in attending  meetings.  Because  PaineWebber,  Mitchell
Hutchins  and,  as  applicable,  a  sub-adviser  perform  substantially  all the

         PERSONAL TRADING  POLICIES.  The funds,  their  investment  adviser and
their principal  underwriter each have adopted a code of ethics under rule 17j-1
of the Investment  Company Act, which permits  personnel  covered by the Code to
invest in  securities  that may be  purchased or held by a fund,  but  prohibits
fraudulent,  deceptive or manipulative  conduct in connection with that personal
investing. Each sub-adviser also has adopted a code of ethics under rule 17j-1.

         DISTRIBUTION ARRANGEMENTS. Mitchell Hutchins acts as the distributor of
the Class I shares of each fund  under a  distribution  contract  with the Trust
("Distribution  Contract"). The Distribution Contract requires Mitchell Hutchins
to use its best efforts,  consistent with its other businesses,  to sell Class I
shares  of  each  fund.  Class H  shares  have no  distributor  or  distribution
contract.  Class H and Class I shares of each fund are offered  continuously  to
separate  accounts of insurance  companies.  Mitchell  Hutchins is located at 51
West 52nd Street, New York, New York 10019-6114.

                                       51
<PAGE>

         Under a plan of  distribution  pertaining to the Class I shares of each
fund  adopted by the Trust in the manner  prescribed  under Rule 12b-1 under the
Investment  Company  Act  ("Class I Plan" or  "Plan"),  each fund pays  Mitchell
Hutchins a distribution  fee, accrued daily and payable  monthly,  at the annual
rate of 0.25% of the  average  daily  net  assets  attributable  to its  Class I
shares.  Mitchell  Hutchins  uses  these  distribution  fees  to  pay  insurance
companies    whose   separate    accounts    purchase   Class   I   shares   for
distribution-related  services that the insurance companies provide with respect
to the Class I shares.  These  services  include (1) the printing and mailing of
fund prospectuses,  SAIs, related supplements and shareholder reports to current
and prospective  contract  owners,  (2) the development and preparation of sales
material, including sales literature,  relating to Class I shares, (3) materials
and activities  intended to educate and train insurance  company sales personnel
concerning the funds and Class I shares, (4) obtaining information and providing
explanations to contract owners concerning the funds, (5) compensating insurance
company  sales  personnel  with  respect to services  that result in the sale or
retention of Class I shares,  (6) providing  personal  services  and/or  account
maintenance  services  to  contract  owners with  respect to  insurance  company
separate  accounts that hold Class I shares,  and (7) financing other activities
that the board determines are primarily  intended to result in the sale of Class
I shares.

         The Plan  and the  related  Distribution  Contract  for  Class I shares
specify  that  the  distribution   fees  paid  to  Mitchell   Hutchins  are  not
reimbursements  for  specific  expenses  incurred.  Therefore,  even if Mitchell
Hutchins' expenses exceed the distribution fees it receives,  the funds will not
be  obligated  to pay more than  those  fees.  On the other  hand,  if  Mitchell
Hutchins'  expenses  are less than such fees,  it will  retain its full fees and
realize a profit.  Expenses in excess of  distribution  fees received or accrued
through the termination date of the Class I Plan will be Mitchell Hutchins' sole
responsibility and not that of the funds. The board reviews the Class I Plan and
Mitchell Hutchins' corresponding expenses annually.

         Among  other  things,  the  Class I Plan  provides  that  (1)  Mitchell
Hutchins will submit to the board at least quarterly, and the board members will
review,  reports  regarding all amounts  expended under the Class I Plan and the
purposes  for  which  such  expenditures  were  made,  (2) the Class I Plan will
continue in effect only so long as it is  approved  at least  annually,  and any
material  amendment  thereto is approved,  by the board,  including  those board
members who are not "interested  persons" of the Trust and who have no direct or
indirect  financial  interest  in the  operation  of the  Plan or any  agreement
related to the Plan, acting in person at a meeting called for that purpose,  (3)
payments  by a fund  under the Class I Plan  shall not be  materially  increased
without the  affirmative  vote of the  holders of a majority of the  outstanding
shares of the  relevant  class and (4) while the Class I Plan remains in effect,
the selection and nomination of board members who are not  "interested  persons"
of the Trust shall be committed to the  discretion  of the board members who are
not "interested persons" of that Trust.

         During the year ended  December 31, 1999, the funds paid or accrued the
following  distribution fees to Mitchell Hutchins for their Class I shares under
the Plan, and Mitchell Hutchins waived the amounts shown:

<PAGE>

         In approving the Class I Plan for each fund,  the board  considered all
the features of the  distribution  system for the Class I shares,  including (1)
the  expectation  that Class I shares  would be sold  primarily  to the separate
accounts  of  insurance   companies   unaffiliated  with  Mitchell  Hutchins  or
PaineWebber, (2) the expenses those unaffiliated insurance companies were likely
to incur in marketing Class I shares to the owners of contracts  issued by their
separate  accounts,  (3) the  need to  encourage  those  unaffiliated  insurance
companies to educate their agents  concerning  the fund and to compensate  their
agents  for  selling  Class  I  shares  and  (4) the  need  to  encourage  those
unaffiliated insurance companies to educate their contract owners concerning the
fund and to provide personal and account maintenance services to contract owners
with respect to the fund's Class I shares attributable to their accounts.

         The board also considered all compensation that Mitchell Hutchins would
receive  under the Class I Plan and the  Distribution  Contract and the benefits
that would accrue to Mitchell  Hutchins  under the Class I Plan in that Mitchell
Hutchins would receive  distribution and advisory fees that are calculated based
upon a percentage of the average net assets of a fund, which fees would increase
if the  Class I Plan  were  successful  and the  fund  attained  and  maintained
significant asset levels.

                             PORTFOLIO TRANSACTIONS

         Subject to policies established by the board,  Mitchell Hutchins or the
applicable sub-adviser is responsible for the execution of each fund's portfolio
transactions  and  the  allocation  of  brokerage  transactions.   In  executing
portfolio transactions, Mitchell Hutchins or the sub-adviser seeks to obtain the
best net  results  for a fund,  taking into  account  such  factors as the price
(including the applicable brokerage commission or dealer spread), size of order,
difficulty of execution and operational  facilities of the firm involved.  While
Mitchell  Hutchins or the  sub-adviser  generally seeks  reasonably  competitive
commission rates, payment of the lowest commission is not necessarily consistent
with  obtaining  the best net  results.  Prices  paid to  dealers  in  principal
transactions  generally include a "spread," which is the difference  between the
prices at which the dealer is willing to purchase  and sell a specific  security
at the time.  Generally,  bonds are traded on the  over-the-counter  market on a
"net" basis without a stated  commission  through  dealers  acting for their own
accounts and not through brokers.  Each fund may invest in securities  traded in
the over-the-counter markets and will engage primarily with the dealers who make
markets in such securities, unless a better price or execution could be obtained
by using a broker.

         During  the  fiscal  years  indicated,  the  funds  paid the  brokerage
commissions set forth below:

         The  funds  have no  obligation  to deal  with any  broker  or group of
brokers in the execution of portfolio transactions.  The funds contemplate that,

including  PaineWebber,  or brokerage  affiliates of a fund's  sub-adviser.  The
board has adopted  procedures in conformity with Rule 17e-1 under the Investment
Company Act to ensure that all  brokerage  commissions  paid to  PaineWebber  or
brokerage  affiliates of a fund's sub-adviser are reasonable and fair.  Specific
provisions in the Advisory  Contracts and the Sub-Advisory  Contracts  authorize
Mitchell  Hutchins  and  each  sub-adviser,   respectively,  and  any  of  their
affiliates  that is a  member  of a  national  securities  exchange,  to  effect
portfolio  transactions  for the applicable  fund on such exchange and to retain
compensation in connection with such transactions. Any such transactions will be
effected and related  compensation  paid only in accordance  with applicable SEC
regulations.

         During the fiscal years indicated, the funds paid brokerage commissions
to PaineWebber  or, as applicable,  brokerage  affiliates of the  sub-adviser as
follows:

         Transactions  in  futures   contracts  are  executed   through  futures
commission  merchants  ("FCMs"),  who receive  brokerage  commissions  for their
services.  The funds' procedures in selecting FCMs to execute their transactions

                                       54
<PAGE>

in  futures  contracts,  including  procedures  permitting  the use of  Mitchell
Hutchins and its  affiliates  or brokerage  affiliates of the  sub-adviser,  are
similar to those in effect with respect to brokerage transactions in securities.

         In selecting brokers,  Mitchell Hutchins or a sub-adviser will consider
the full range and quality of a broker's services. Consistent with the interests
of the funds and  subject to the review of each  board,  Mitchell  Hutchins or a
sub-adviser may cause a fund to purchase and sell portfolio  securities  through
brokers who provide  Mitchell  Hutchins or the  sub-adviser  with  brokerage  or
research services.  The funds may pay those brokers a higher commission than may
be charged by other brokers,  provided that Mitchell Hutchins or the sub-adviser
determines  in good faith that such  commission is reasonable in terms either of
that  particular  transaction  or of  the  overall  responsibility  of  Mitchell
Hutchins or the sub-adviser, as applicable, to that fund and its other clients.

         Research  services  obtained from brokers may include written  reports,
pricing and appraisal  services,  analysis of issues raised in proxy statements,
educational  seminars,  subscriptions,   portfolio  attribution  and  monitoring
services, and computer hardware,  software and access charges which are directly
related to investment research. Research services may be received in the form of
written reports, online services,  telephone contacts and personal meetings with
securities  analysts,  economists,  corporate  and  industry  spokespersons  and
government representatives.

         For the year ended  December 31, 1999, the funds directed the portfolio
transactions  indicated  below to brokers chosen because they provide  research,
analysis,  advice and similar  services,  for which the funds paid the brokerage
commissions indicated below:

         For purchases or sales with broker-dealer  firms that act as principal,
Mitchell Hutchins or the applicable  sub-adviser seeks best execution.  Although
Mitchell  Hutchins or a sub-adviser  may receive  certain  research or execution
services  in  connection  with these  transactions,  Mitchell  Hutchins  and the
sub-adviser will not purchase securities at a higher price or sell securities at
a lower price than would  otherwise be paid if no weight was  attributed  to the
services provided by the executing dealer.  Mitchell Hutchins or the sub-adviser
may engage in agency transactions in over-the-counter equity and debt securities
in return for research and execution  services.  These  transactions are entered
into only in compliance with procedures ensuring that the transaction (including
commissions) is at least as favorable as it would have been if effected directly
with a market-maker that did not provide research or execution services.

         Research  services  obtained from brokers may include written  reports,
pricing and appraisal  services,  analysis of issues raised in proxy statements,
educational  seminars,  subscriptions,   portfolio  attribution  and  monitoring
services, and computer hardware,  software and access charges which are directly
related to investment research. Research services may be received in the form of
written reports, online services,  telephone contacts and personal meetings with
securities  analysts,  economists,  corporate  and  industry  spokespersons  and
government representatives.

         Investment  decisions  for a fund  and for  other  investment  accounts
managed  by  Mitchell  Hutchins  or  by  the  applicable  sub-adviser  are  made
independently of each other in light of differing considerations for the various
accounts.  However,  the same investment decision may occasionally be made for a
fund and one or more of such accounts. In such cases,  simultaneous transactions
are  inevitable.  Purchases or sales are then averaged as to price and allocated
between that fund and such other  account(s) as to amount according to a formula
deemed  equitable  to the fund and such  account(s).  While in some  cases  this
practice could have a detrimental effect upon the price or value of the security
as far as a fund is concerned, or upon its ability to complete its entire order,
in other cases it is believed that  coordination  and the ability to participate
in volume transactions will be beneficial to the fund.

         The  funds  will  not   purchase   securities   that  are   offered  in
underwritings in which  PaineWebber,  an applicable  sub-adviser or any of their
affiliates is a member of the underwriting or selling group,  except pursuant to
procedures  adopted by the board  pursuant  to Rule 10f-3  under the  Investment
Company Act.  Among other things,  these  procedures  require that the spread or
commission  paid in connection  with such a purchase be reasonable and fair, the
purchase be at not more than the public  offering  price prior to the end of the
first business day after the date of the public offering and that PaineWebber or
any affiliate  thereof or an affiliate of the  sub-adviser not participate in or
benefit from the sale to the funds.

         As of  December  31,  1999,  the funds owned  securities  issued by the
following companies which are regular broker-dealers for the funds:

         PORTFOLIO TURNOVER. The funds' annual portfolio turnover rates may vary
greatly  from  year to  year,  but  they  will  not be a  limiting  factor  when
management deems portfolio changes  appropriate.  The portfolio turnover rate is
calculated  by dividing  the lesser of a fund's  annual  sales or  purchases  of
portfolio  securities  (exclusive  of  purchases  or sales of  securities  whose
maturities  at the time of  acquisition  were  one year or less) by the  monthly
average value of securities in the portfolio during the year.

         The funds'  respective  portfolio  turnover  rates for the fiscal years
shown were:

         * These funds commenced operations on September 28, 1998.

         Strategic Fixed Income Portfolio  experienced a significant increase in
portfolio  turnover in 1999 because its  sub-adviser  took  advantage of several
mispricings in the mortgage-backed securities market.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

         The insurance  company separate  accounts purchase and redeem shares of
the funds on each day on which the New York Stock  Exchange  is open for trading
("Business Day") based on, among other things, the amount of premium payments to
be invested and  surrendered  and  transfer  requests to be effected on that day
pursuant to the variable  contracts.  Currently  the New York Stock  Exchange is
closed on the  observance  of the  following  holidays:  New Year's Day,  Martin
Luther King, Jr. Day, Presidents' Day, Good Friday,  Memorial Day,  Independence
Day, Labor Day, Thanksgiving Day and Christmas Day. Purchases and redemptions of
the shares of each fund are  effected at their  respective  net asset values per
share determined as of the close of regular trading (usually 4:00 p.m.,  Eastern
time)  on the  New  York  Stock  Exchange  on that  Business  Day.  Payment  for
redemptions  are made by the  funds  within  seven  days  thereafter.  No fee is
charged the separate accounts when they purchase or redeem fund shares.

         The funds may suspend  redemption  privileges  or postpone  the date of
payment  during any period  (1) when the New York  Stock  Exchange  is closed or
trading on the New York Stock  Exchange is  restricted as determined by the SEC,
(2)  when an  emergency  exists,  as  defined  by the  SEC,  that  makes  it not
reasonably practicable for a fund to dispose of securities owned by it or fairly
to determine the value of its assets or (3) as the SEC may otherwise permit. The
redemption price may be more or less than the shareholder's  cost,  depending on
the market value of a fund's portfolio at the time.

                               VALUATION OF SHARES

         Each fund determines its net asset value per share  separately for each
class of shares, normally as of the close of regular trading (usually 4:00 p.m.,
Eastern time) on the New York Stock  Exchange on each Monday through Friday when
the New York Stock Exchange is open. Prices will be calculated  earlier when the
New York Stock  Exchange  closes early  because  trading has been halted for the
day.

         Securities that are listed on U.S. and foreign stock exchanges normally
are  valued at the last sale  price on the day the  securities  are  valued  or,
lacking any sales on that day, at the last  available bid price.  In cases where
securities  are traded on more than one exchange,  the  securities are generally
valued  on the  exchange  considered  by  Mitchell  Hutchins  or the  applicable
sub-adviser as the primary  market.  Securities  traded in the  over-the-counter
market and listed on The Nasdaq Stock Market  ("Nasdaq")  normally are valued at
the  last   available   sale  price  on  Nasdaq   prior  to   valuation;   other
over-the-counter  securities are valued at the last bid price available prior to
valuation, other than short-term investments that mature in 60 days or less.

         Where  market  quotations  are  readily  available,  bonds of the funds
(other than Money Market  Portfolio)  are valued  based upon market  quotations,
provided  those  quotations  adequately  reflect,  in the  judgment  of Mitchell
Hutchins or the applicable sub-adviser,  the fair value of the securities. Where
those market quotations are not readily  available,  bonds are valued based upon
appraisals received from a pricing service using a computerized matrix system or
based upon  appraisals  derived  from  information  concerning  the  security or
similar  securities  received from recognized  dealers in those securities.  The
amortized cost method of valuation  generally is used to value debt  obligations
with 60 days or less remaining until maturity,  unless the board determines that
this does not represent  fair value.  All other  securities and other assets are
valued at fair value as  determined  in good faith by or under the  direction of
the board.

         It should be  recognized  that  judgment  often plays a greater role in
valuing  thinly  traded  securities  and lower rated bonds than is the case with
respect  to  securities  for which a  broader  range of  dealer  quotations  and
last-sale information is available.

         All investments quoted in foreign currency will be valued daily in U.S.
dollars on the basis of the foreign  currency  exchange  rate  prevailing at the
time such  valuation  is  determined  by a fund's  custodian.  Foreign  currency
exchange rates are generally determined prior to the close of regular trading on
the New York Stock Exchange.  Occasionally events affecting the value of foreign
investments  and such  exchange  rates occur  between the time at which they are
determined and the close of trading on the New York Stock Exchange, which events
would not be  reflected in the  computation  of a fund's net asset value on that
day. If events  materially  affecting the value of such  investments or currency
exchange rates occur during such time period,  the investments will be valued at
their fair value as  determined  in good faith by or under the  direction of the
board.  The foreign currency  exchange  transactions of the funds conducted on a
spot (that is, cash) basis are valued at the spot rate for purchasing or selling
currency  prevailing  on  the  foreign  exchange  market.  Under  normal  market
conditions  this rate differs  from the  prevailing  exchange  rate by less than
one-tenth  of one percent due to the costs of  converting  from one  currency to
another.

         MONEY MARKET  PORTFOLIO.  Money Market  Portfolio  values its portfolio
securities in accordance  with the amortized cost method of valuation under Rule
2a-7  under the  Investment  Company  Act.  To use  amortized  cost to value its
portfolio securities, the fund must adhere to certain conditions under that Rule
relating to its investments. Amortized cost is an approximation of market value,
whereby  the  difference  between  acquisition  cost and  value at  maturity  is
amortized on a  straight-line  basis over the remaining life of the  instrument.
The  effect  of  changes  in the  market  value of a  security  as a  result  of
fluctuating interest rates is not taken into account and thus the amortized cost
method of valuation may result in the value of a security  being higher or lower
than its actual  market value.  In the event that a large number of  redemptions
takes place at a time when interest rates have increased, the fund might have to
sell portfolio  securities prior to maturity and at a price that might not be as
desirable as the value at maturity.

         The board has  established  procedures for the purpose of maintaining a
constant  net asset value of $1.00 per share for Money Market  Portfolio,  which
include a review of the extent of any  deviation  of net asset  value per share,
based on available market  quotations,  from the $1.00 amortized cost per share.
Should that  deviation  exceed 1/2 of 1%, the trustees  will  promptly  consider
whether any action should be initiated to eliminate or reduce material  dilution
or other  unfair  results to  shareholders.  Such action may  include  redeeming

                                       58
<PAGE>

shares in kind,  selling  portfolio  securities  prior to maturity,  reducing or
withholding dividends and utilizing a net asset value per share as determined by
using available market quotations. Money Market Portfolio will maintain a dollar
weighted average portfolio maturity of 90 days or less and will not purchase any
instrument with a remaining maturity greater than 13 months (as calculated under
Rule 2a-7) and except that securities subject to repurchase  agreements may have
maturities in excess of 13 months.  Money Market  Portfolio will limit portfolio
investments,  including repurchase agreements,  to those U.S. dollar denominated
instruments  that are of high  quality and that the trustees  determine  present
minimal  credit  risks as advised by  Mitchell  Hutchins  and will  comply  with
certain  reporting  and  recordkeeping  procedures.  There is no assurance  that
constant net asset value per share will be  maintained.  In the event  amortized
cost ceases to represent fair value, the board will take appropriate action.

         In determining the approximate  market value of portfolio  instruments,
the Trust may employ  outside  organizations,  which may use a matrix or formula
method that takes into consideration market indices,  matrices, yield curves and
other specific adjustments.  This may result in the securities being valued at a
price different from the price that would have been determined had the matrix or
formula method not been used.  All cash,  receivables  and current  payables are
carried at their face value.  Other assets,  if any, are valued at fair value as
determined in good faith by or under the direction of the board.

                                      TAXES

         Fund shares are offered only to  insurance  company  separate  accounts
that fund benefits under certain variable annuity contracts and/or variable life
insurance contracts.  See the applicable contract prospectus for a discussion of
the special  taxation of insurance  companies with respect to those accounts and
the contract holders.

         QUALIFICATION AS REGULATED INVESTMENT  COMPANIES.  Each fund is treated
as a separate  corporation  for  federal  income tax  purposes.  To  continue to
qualify for treatment as a regulated investment company ("RIC") under Subchapter
M of the  Internal  Revenue  Code  ("Code"),  each fund must  distribute  to its
shareholders  for each  taxable  year at  least  90% of its  investment  company
taxable income  (consisting  generally of net investment  income, net short-term
capital  gains  and  net  gains  from  certain  foreign  currency  transactions)
("Distribution Requirement") and must meet several additional requirements.  For
each fund, these requirements include the following: (1) the fund must derive at
least 90% of its gross  income  each  taxable  year  from  dividends,  interest,
payments  with  respect  to  securities  loans and gains  from the sale or other
disposition  of securities  or foreign  currencies,  or other income  (including
gains from options,  futures or forward  contracts)  derived with respect to its
business of investing in securities or those currencies ("Income  Requirement");
(2) at the close of each quarter of the fund's taxable year, at least 50% of the
value of its total  assets  must be  represented  by cash and cash  items,  U.S.
government securities, securities of other RICs and other securities, with these
other securities  limited,  in respect of any one issuer, to an amount that does
not  exceed  5% of the  value of the  fund's  total  assets  and  that  does not
represent more than 10% of the issuer's  outstanding voting securities;  and (3)
at the close of each quarter of the fund's  taxable  year,  not more than 25% of
the value of its total  assets may be  invested in  securities  (other than U.S.
government  securities or the  securities  of other RICs) of any one issuer.  By
qualifying  as a RIC,  a fund (but not its  shareholders)  will be  relieved  of
federal income tax on the part of its investment  company taxable income and net
capital gain (i.e., the excess of net long-term capital gain over net short-term
capital loss) that it distributes to its shareholders.

         If a fund  failed to qualify  for  treatment  as a RIC for any  taxable
year, (1) it would be taxed as an ordinary corporation on the full amount of its
taxable  income  for  that  year  (even if it  distributed  that  income  to its
shareholders),  (2) all distributions out of its earnings and profits, including
distributions  of net  capital  gain,  would be taxable to its  shareholders  as
dividends (that is, ordinary  income) and (3) most  importantly,  each insurance
company  separate  account  invested  in the  fund  would  fail to  satisfy  the
diversification requirements of section 817(h) of the Code described in the next
paragraph,  with the result that the  variable  annuity  and/or  life  insurance
contracts  supported  by that  account  would  no  longer  be  eligible  for tax
deferral. In addition, the fund could be required to recognize unrealized gains,
pay substantial  taxes and interest and make  substantial  distributions  before
requalifying for RIC treatment.

         ADDITIONAL DIVERSIFICATION REQUIREMENTS.  Each fund intends to continue
to satisfy the diversification  requirements indirectly imposed on it by section
817(h) of the Code and the regulations thereunder,  which are in addition to the
diversification  requirements  described above. These requirements place certain

                                       59
<PAGE>

limitations on the assets of each insurance company separate account that may be
invested in the  securities of a single issuer.  Because  section 817(h) and the
regulations  thereunder  treat the assets of each fund as assets of the  related
separate account, the funds must also meet these requirements. Specifically, the
regulations  under section 817(h) provide that, except as permitted by the "safe
harbor"  described  below,  as of the end of each calendar  quarter or within 30
days  thereafter,  no  more  than  55%  of the  total  assets  of a fund  may be
represented by any one investment,  no more than 70% by any two investments,  no
more  than  80% by any  three  investments  and no  more  than  90% by any  four
investments.  For this purpose, all securities of the same issuer are considered
a single  investment,  and each U.S.  government agency and  instrumentality  is
considered a separate issuer.  Section 817(h) provides, as a safe harbor, that a
separate  account  will  be  treated  as  being  adequately  diversified  if the
diversification  requirements  under Subchapter M are satisfied and no more than
55% of the value of the separate account's total assets are cash and cash items,
government securities and securities of other RICs. Failure of a fund to satisfy
the section  817(h)  requirements  would result in (1) taxation of the insurance
company issuing the variable  contracts,  the benefits under which are funded by
the separate account(s) investing in the fund, and (2) treatment of the contract
owners other than as described in the applicable contract prospectus.

         OTHER  INFORMATION.  The use of  hedging  strategies,  such as  writing
(selling) and purchasing options and futures contracts and entering into forward
currency  contracts,  involves  complex rules that will determine for income tax
purposes the amount, character and timing of recognition of the gains and losses
a fund realizes in connection  therewith.  Gains from the disposition of foreign
currencies  (except  certain gains that may be excluded by future  regulations),
and gains from options, futures and forward currency contracts derived by a fund
with respect to its business of investing in securities  or foreign  currencies,
will be treated as qualifying income under the Income Requirement.

         Investment  income  earned  and  gains  realized  by a fund on  foreign
securities  may be subject  to income,  withholding  or other  taxes  imposed by
foreign  countries  and U.S.  possessions  that would reduce the return on those
securities.   Tax  treaties  between  the  United  States  and  certain  foreign
countries,  however,  may reduce or  eliminate  these  taxes,  and many  foreign
countries  do not impose  taxes on capital  gains in respect of  investments  by
foreign investors.

         A  fund  may  invest  in  the  stock  of  "passive  foreign  investment
companies"  ("PFICs") if that stock is a permissible  investment.  A PFIC is any
foreign corporation (with certain exceptions) that, in general,  meets either of
the following  tests:  (1) at least 75% of its gross income is passive or (2) an
average of at least 50% of its assets  produce,  or are held for the  production
of,  passive  income.  Under  certain  circumstances,  a fund will be subject to
federal  income tax on a portion of any  "excess  distribution"  received on the
stock of a PFIC or of any gain  from  disposition  of that  stock  (collectively
"PFIC income"),  plus interest  thereon,  even if the fund  distributes the PFIC
income as a taxable dividend to its shareholders. The balance of the PFIC income
will  be  included  in  the  fund's  investment   company  taxable  income  and,
accordingly,  will not be taxable to it to the extent it distributes that income
to its shareholders.

         If a fund  invests  in a  PFIC  and  elects  to  treat  the  PFIC  as a
"qualified  electing  fund"  ("QEF"),  then  in lieu  of the  foregoing  tax and
interest  obligation,  the fund will be  required to include in income each year
its pro rata share of the QEF's annual ordinary earnings and net capital gain --
which it may have to  distribute  to satisfy the  Distribution  Requirement  and
avoid  imposition of the Excise Tax -- even if the QEF did not distribute  those
earnings and gain to the fund. In most instances it will be very  difficult,  if
not impossible, to make this election because of certain of its requirements.

         Each  fund  may  elect  to  "mark to  market"  its  stock in any  PFIC.
"Marking-to-market,"  in this context,  means  including in ordinary income each
taxable year the excess, if any, of the fair market value of a PFIC's stock over
a fund's  adjusted  basis  therein as of the end of that year.  Pursuant  to the
election,  a fund also would be allowed to deduct (as an ordinary,  not capital,
loss) the  excess,  if any,  of its  adjusted  basis in PFIC stock over the fair
market value thereof as of the taxable  year-end,  but only to the extent of any
net  mark-to-market  gains with  respect to that stock  included by the fund for
prior taxable years under the election (and under  regulations  proposed in 1992
that provided a similar  election with respect to the stock of certain PFICs). A
fund's  adjusted  basis in each PFIC's  stock with  respect to which it has made
this  election  will be adjusted to reflect the amounts of income  included  and
deductions taken thereunder.


                                       60
<PAGE>

         Certain futures and foreign  currency  contracts and listed  non-equity
options (such as those on a securities  index) in which a fund may invest may be
subject to section 1256 of the Internal Revenue Code ("section 1256 contracts").
Any  section  1256  contracts  a fund  holds  at the  end of each  taxable  year
generally  must be  "marked-to-market"  (that is, treated as having been sold at
that time for their fair market value) for federal income tax purposes, with the
result  that  unrealized  gains or losses  will be treated  as though  they were
realized.  Sixty  percent  of any net gain or loss  recognized  on these  deemed
sales, and 60% of any net realized gain or loss from any actual sales of section
1256  contracts,  will be treated as  long-term  capital  gain or loss,  and the
balance  will be treated as  short-term  capital  gain or loss.  These rules may
operate  to  increase  the amount  that a fund must  distribute  to satisfy  the
Distribution   Requirement  (i.e.,  with  respect  to  the  portion  treated  as
short-term  capital gain), which will be taxable to its shareholders as ordinary
income,  and to increase  the net  capital  gain a fund  recognizes,  without in
either case  increasing  the cash available to the fund. A fund may elect not to
have the  foregoing  rules apply to any "mixed  straddle"  (that is, a straddle,
clearly  identified by the fund in accordance  with applicable  regulations,  at
least one (but not all) the  positions  of which are  section  1256  contracts),
although doing so may have the effect of increasing  the relative  proportion of
net short-term capital gain (taxable as ordinary income) and thus increasing the
amount of dividends that must be distributed.

         Offsetting positions in any actively traded security,  option,  futures
or forward  currency  contract  entered into or held by a fund may  constitute a
"straddle"  for federal  income tax  purposes.  Straddles are subject to certain
rules that may affect the  amount,  character  and timing of a fund's  gains and
losses with  respect to  positions  of the  straddle by  requiring,  among other
things,  that (1) loss realized on  disposition of one position of a straddle be
deferred to the extent of any  unrealized  gain in an offsetting  position until
the latter  position is disposed  of, (2) the fund's  holding  period in certain
straddle  positions  not  begin  until  the  straddle  is  terminated  (possibly
resulting in gain being  treated as  short-term  rather than  long-term  capital
gain) and (3) losses recognized with respect to certain straddle positions, that
otherwise would constitute  short-term  capital losses,  be treated as long-term
capital losses.  Applicable  regulations also provide certain "wash sale" rules,
which  apply  to  transactions  where a  position  is  sold at a loss  and a new
offsetting  position is acquired  within a prescribed  period,  and "short sale"
rules applicable to straddles.  Different  elections are available to the funds,
which may mitigate the effects of the straddle rules,  particularly with respect
to mixed straddles.

         When a covered call option  written  (sold) by a fund expires,  it will
realize a short-term capital gain equal to the amount of the premium it received
for writing the option.  When a fund  terminates its  obligations  under such an
option by entering  into a closing  transaction,  it will  realize a  short-term
capital gain (or loss), depending on whether the cost of the closing transaction
is less (or more) than the premium it received when it wrote the option.  When a
covered call option written by a fund is exercised,  the fund will be treated as
having sold the underlying  security,  producing long-term or short-term capital
gain or loss,  depending on the holding  period of the  underlying  security and
whether the sum of the option price received on the exercise plus the premium it
received  when it  wrote  the  option  is more or less  than  the  basis  of the
underlying security.

         If a fund has an  "appreciated  financial  position" --  generally,  an
interest  (including an interest through an option,  futures or forward currency
contract or short sale) with respect to any stock,  debt instrument  (other than
"straight debt") or partnership  interest the fair market value of which exceeds
its adjusted basis -- and enters into a "constructive sale" of the position, the
fund will be treated as having made an actual sale thereof, with the result that
gain will be recognized at that time. A constructive sale generally  consists of
a short sale, an offsetting  notional principal contract or a futures or forward
currency contract entered into by a fund or a related person with respect to the
same or  substantially  identical  property.  In  addition,  if the  appreciated
financial position is itself a short sale or such a contract, acquisition of the
underlying  property  or  substantially  identical  property  will be  deemed  a
constructive  sale.  The  foregoing  will  not  apply,   however,  to  a  fund's
transaction  during  any  taxable  year that  otherwise  would be  treated  as a
constructive  sale if the  transaction is closed within 30 days after the end of
that year and the fund holds the appreciated  financial position unhedged for 60
days after that  closing  (i.e.,  at no time during  that  60-day  period is the
fund's  risk of loss  regarding  that  position  reduced  by reason  of  certain
specified  transactions  with  respect  to  substantially  identical  or related
property,  such as having an option to sell,  being  contractually  obligated to
sell, making a short sale or granting an option to buy  substantially  identical
stock or securities).

         A fund may  acquire  (1) zero  coupon or other  securities  issued with
original issue discount ("OID") or (2) Treasury  inflation-protected  securities


                                       61
<PAGE>

("TIPS"),  on which principal is adjusted based on changes in the Consumer Price
Index.  A fund must  include in its gross  income the OID that  accrues on those
securities,  and the  amount of any  principal  increases  on TIPS,  during  the
taxable year, even if the fund receives no corresponding  payment on them during
the year. Similarly,  a fund that invests in payment-in-kind  ("PIK") securities
must include in its gross income  securities  it receives as "interest" on those
securities.  Each fund has elected similar  treatment with respect to securities
purchased at a discount  from their face value  ("market  discount").  Because a
fund  annually  must  distribute  substantially  all of its  investment  company
taxable  income,  including any accrued OID,  market discount and other non-cash
income,  to  satisfy  the  Distribution  Requirement,  it may be  required  in a
particular  year to  distribute as a dividend an amount that is greater than the
total amount of cash it actually receives.  Those distributions would have to be
made from the fund's  cash  assets or from the  proceeds  of sales of  portfolio
securities,  if  necessary.  A fund might  realize  capital gains or losses from
those sales,  which would  increase or decrease its investment  company  taxable
income and/or net capital gain.

         The  foregoing  is only a  general  summary  of  some of the  important
federal  income  tax  considerations  generally  affecting  the  funds and their
shareholders.  No  attempt  is made to  present a  complete  explanation  of the
federal tax  treatment  of the funds'  activities,  and this  discussion  is not
intended  as a  substitute  for  careful tax  planning.  Accordingly,  potential
investors  are  urged to  consult  their  own tax  advisers  for  more  detailed
information  and for  information  regarding  any state,  local or foreign taxes
applicable to the funds and to dividends and other distributions therefrom.

                                    DIVIDENDS

         MONEY MARKET PORTFOLIO.  Shares of Money Market Portfolio begin earning
dividends on the day of purchase;  dividends are accrued to shareholder accounts
daily and are automatically invested in additional fund shares monthly. The fund
does not expect to realize net capital gain. If a shareholder redeems all of its
Money Market Portfolio shares,  all accrued dividends  declared on the shares up
to the date of redemption are credited to the shareholder's account.

         The board may revise the above dividend  policy or postpone the payment
of dividends if the fund has or anticipates any large unexpected  expense,  loss
or  fluctuation  in net assets that,  in the opinion of the board,  might have a
significant adverse effect on shareholders.  To date, no situation has arisen to
cause the board to take any such action.

                                OTHER INFORMATION

         MASSACHUSETTS  BUSINESS  TRUST.  The  Trust  is an  entity  of the type
commonly known as a  "Massachusetts  business trust." Under  Massachusetts  law,
shareholders of a fund could,  under certain  circumstances,  be held personally
liable  for the  obligations  of the fund or the  Trust.  However,  the  Trust's
Declaration of Trust disclaims  shareholder liability for acts or obligations of
the Trust or a fund and requires that notice of such disclaimer be given in each
note, bond, contract,  instrument,  certificate or undertaking made or issued by
the board  members or by any officers or officer by or on behalf of the Trust or
the fund,  the board  members or any of them in connection  with the Trust.  The
Declaration  of Trust  provides for  indemnification  from the  relevant  fund's
property for all losses and expenses of any shareholder  held personally  liable
for the  obligations  of the fund.  Thus,  the risk of a  shareholder  incurring
financial loss on account of shareholder  liability is limited to  circumstances
in which the fund itself would be unable to meet its obligations,  a possibility
that Mitchell Hutchins believes is remote and not material.  Upon payment of any
liability  incurred by a shareholder  solely by reason of being or having been a
shareholder,  the  shareholder  paying  such  liability  would  be  entitled  to
reimbursement  from the general  assets of the relevant  fund. The board members
intend to conduct each fund's  operations  in such a way as to avoid,  as far as
possible, ultimate liability of the shareholders for liabilities of the fund.

         VOTING  RIGHTS.  The  insurance  company  separate  accounts  that fund
benefits  under variable  annuity or variable life  insurance  contracts are the
shareholders  of the  funds -- not the  individual  owners  of those  contracts.
However,  the  separate  accounts  may pass  through  voting  rights to contract
owners.

         Shareholders  of each fund are entitled to one vote for each full share
held and  fractional  votes for  fractional  shares held.  Voting rights are not
cumulative  and, as a result,  the holders of more than 50% of all the shares of

                                       62
<PAGE>

the Trust may elect all of the board members of the Trust.  The shares of a fund
will be voted together,  except that only the shareholders of a particular class
of a fund may vote on matters  affecting  only that class,  such as the terms of
the Class I Plan as it relates to the Class I shares.  The shares of each series
will be voted  separately,  except when an  aggregate  vote of all the series is
required by law.

         The fund does not hold annual  meetings.  Shareholders  of record of no
less than two-thirds of the  outstanding  shares of the Trust may remove a board
member through a declaration in writing or by vote cast in person or by proxy at
a meeting  called  for that  purpose.  A  meeting  will be called to vote on the
removal  of a board  member at the  written  request  of  holders  of 10% of the
outstanding shares of the Trust.

         POSSIBLE  CONFLICTS.  Shares of the  funds may serve as the  underlying
investments for separate accounts of unaffiliated  insurance  companies ("shared
funding")  as well as for both  annuity  and life  insurance  contracts  ("mixed
funding").  Due to  differences  in tax treatment or other  considerations,  the
interests of various  contract  owners  might at some time be in  conflict.  The
Trust does not  currently  foresee any  conflict.  However,  the  Trust's  board
intends to monitor events to identify any material  irreconcilable conflict that
may arise and to determine what action,  if any,  should be taken in response to
such  conflict.  If  such a  conflict  were  to  occur,  one or  more  insurance
companies'  separate  accounts might be required to withdraw its  investments in
one or more funds. This might force a fund to sell securities at disadvantageous
prices.

         CLASSES  OF  SHARES.  A share  of each  class of a fund  represents  an
identical interest in that fund's investment  portfolio and has the same rights,
privileges  and  preferences.  However,  each class may differ  with  respect to
distribution fees, if any, other expenses  allocable  exclusively to each class,
voting  rights on matters  exclusively  affecting  that class,  and its exchange
privilege, if any. The different expenses applicable to the different classes of

                               RATINGS INFORMATION

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS

         Aaa.  Bonds  which are rated Aaa are judged to be of the best  quality.
They carry the smallest degree of investment risk and are generally  referred to
as  "gilt  edged."  Interest  payments  are  protected  by  a  large  or  by  an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the  fundamentally  strong position of such issues;  Aa.
Bonds  which are rated Aa are  judged to be of high  quality  by all  standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds.  They are rated lower than the best bonds  because  margins of protection
may not be as large as in Aaa securities or  fluctuation of protective  elements
may be of greater  amplitude or there may be other  elements  present which make
the long term risk appear somewhat larger than in Aaa securities; A. Bonds which
are  rated  A  possess  many  favorable  investment  attributes  and  are  to be
considered  as  upper-medium-grade  obligations.   Factors  giving  security  to
principal  and interest  are  considered  adequate,  but elements may be present
which suggest a susceptibility to impairment  sometime in the future; Baa. Bonds
which are rated Baa are considered as medium-grade  obligations,  i.e., they are
neither  highly  protected nor poorly  secured.  Interest  payment and principal
security appear adequate for the present but certain protective  elements may be
lacking or may be  characteristically  unreliable over any great length of time.
Such  bonds  lack  outstanding  investment  characteristics  and  in  fact  have
speculative  characteristics as well; Ba. Bonds which are rated Ba are judged to
have  speculative  elements;  their future cannot be considered as well-assured.
Often the protection of interest and principal payments may be very moderate and
thereby  not well  safeguarded  during  both good and bad times over the future.
Uncertainty of position  characterizes  bonds in this class;  B. Bonds which are
rated B generally lack characteristics of the desirable investment. Assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long period of time may be small; Caa. Bonds which are rated Caa are of
poor standing. Such issues may be in default or there may be present elements of
danger with  respect to  principal  or  interest;  Ca.  Bonds which are rated Ca
represent  obligations  which are speculative in a high degree.  Such issues are
often in default or have other marked  shortcomings;  C. Bonds which are rated C
are the lowest  rated  class of bonds,  and issues so rated can be  regarded  as
having extremely poor prospects of ever attaining any real investment standing.

         Note: Moody's applies numerical  modifiers,  1, 2 and 3 in each generic
rating  classification  from Aa through Caa.  The modifier 1 indicates  that the
obligation ranks in the higher end of its generic rating category,  the modifier
2 indicates a mid-range  ranking,  and the modifier 3 indicates a ranking in the
lower end of that generic rating category.

DESCRIPTION OF S&P Corporate Debt Ratings

         AAA. An obligation  rated AAA has the highest  rating  assigned by S&P.
The  obligor's  capacity to meet its financial  commitment on the  obligation is
extremely  strong;  AA. An  obligation  rated AA differs from the highest  rated
obligations only in small degree.  The obligor's  capacity to meet its financial
commitment  on the  obligation  is  very  strong;  A. An  obligation  rated A is
somewhat more susceptible to the adverse effects of changes in circumstances and
economic  conditions than obligations in higher rated categories.  However,  the
obligor's  capacity to meet its financial  commitment on the obligation is still
strong;  BBB. An obligation rated BBB exhibits adequate  protection  parameters.
However,  adverse economic conditions or changing  circumstances are more likely
to lead to a weakened  capacity of the obligor to meet its financial  commitment
on the obligation; BB, B, CCC, CC, C. Obligations rated BB, B, CCC, CC and C are
regarded as having  significant  speculative  characteristics.  BB indicates the
least degree of  speculation  and C the  highest.  While such  obligations  will
likely have some quality and protective characteristics, these may be outweighed
by  large  uncertainties  or major  exposures  to  adverse  conditions;  BB.  An
obligation  rated BB is less  vulnerable  to nonpayment  than other  speculative
issues.  However,  it faces major ongoing  uncertainties  or exposure to adverse
business,  financial,  or economic  conditions which could lead to the obligor's
inadequate  capacity to meet its financial  commitment on the obligation;  B. An
obligation rated B is more vulnerable to nonpayment than  obligations  rated BB,
but the obligor  currently has the capacity to meet its financial  commitment on
the obligation.  Adverse business, financial, or economic conditions will likely
impair the obligor's capacity or willingness to meet its financial commitment on
the  obligation;  CCC.  An  obligation  rated  CCC is  currently  vulnerable  to

                                       64
<PAGE>

nonpayment  and is dependent  upon  favorable  business,  financial and economic
conditions for the obligor to meet its financial  commitment on the  obligation.
In the event of adverse business, financial, or economic conditions, the obligor
is not  likely to have the  capacity  to meet its  financial  commitment  on the
obligation;  CC.  An  obligation  rated CC is  currently  highly  vulnerable  to
nonpayment;  C. The C rating may be used to cover a situation where a bankruptcy
petition has been filed or similar  action has been taken,  but payments on this
obligation are being continued;  D. An obligation rated D is in payment default.
The D rating category is used when payments on an obligation are not made on the
date due  even if the  applicable  grace  period  has not  expired,  unless  S&P
believes that such payments will be made during such grace period.  The D rating
also will be used upon the filing of a  bankruptcy  petition  or the taking of a
similar action if payments on an obligation are jeopardized.

         CI. The rating CI is reserved  for income bonds on which no interest is
being paid.

         Plus (+) or Minus (-):  The ratings  from "AA" to "CCC" may be modified
by the  addition of a plus or minus sign to show  relative  standing  within the
major rating categories.

         r.  This  symbol  is  attached  to  the  ratings  of  instruments  with
significant  noncredit  risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating. Examples include:
obligations  linked  or  indexed  to  equities,   currencies,   or  commodities;
obligations  exposed  to  severe  prepayment  risk--such  as  interest  only  or
principal  only  mortgage  securities;  and  obligations  with  unusually  risky
interest terms, such as inverse floaters.

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS

         Prime-1.  Issuers  assigned this highest rating have a superior ability
for repayment of senior short-term debt  obligations.  Prime-1 repayment ability
will  often  be  evidenced  by the  following  characteristics:  Leading  market
positions  in well  established  industries;  high  rates  of  return  on  funds
employed;  conservative capitalization structures with moderate reliance on debt
and  ample  asset  protection;  broad  margins  in  earnings  coverage  of fixed
financial charges and high internal cash generation;  well established access to
a range of financial markets and assured sources of alternate liquidity.

         Prime-2.  Issuers  assigned  this  rating  have a  strong  ability  for
repayment of senior short-term debt obligations. This will normally be evidenced
by many of the  characteristics  cited above,  but to a lesser degree.  Earnings
trends and  coverage  ratios,  while sound,  will be more subject to  variation.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternate liquidity is maintained.

         Prime-3.  Issuers assigned this rating have an acceptable  capacity for
repayment   of  senior   short-term   obligations.   The   effect  of   industry
characteristics  and market  composition may be more pronounced.  Variability in
earnings and profitability may result in changes in the level of debt protection
measurements  and may  require  relatively  high  financial  leverage.  Adequate
alternate liquidity is maintained.

         Not Prime.  Issuers  assigned this rating do not fall within any of the
Prime rating categories.

DESCRIPTION OF S&P COMMERCIAL PAPER RATINGS

         A-1. A short-term obligation rated A-1 is rated in the highest category
by  S&P.  The  obligor's  capacity  to  meet  its  financial  commitment  on the
obligation is strong.  Within this category,  certain obligations are designated
with a plus sign (+). This  indicates  that the  obligor's  capacity to meet its
financial commitment on these obligations is extremely strong. A-2. A short-term
obligation  rated A-2 is somewhat  more  susceptible  to the adverse  effects of
changes in  circumstances  and economic  conditions  than  obligations in higher
rating  categories.  However,  the  obligor's  capacity  to meet  its  financial
commitment on the obligation is satisfactory. A-3. A short-term obligation rated
A-3  exhibits  adequate  protection   parameters.   However,   adverse  economic
conditions  or  changing  circumstances  are more  likely to lead to a  weakened
capacity of the obligor to meet its financial commitment on the obligation. B. A
short-term  obligation  rated B is  regarded as having  significant  speculative
characteristics.  The obligor  currently  has the capacity to meet its financial
commitment on the  obligation;  however,  it faces major  ongoing  uncertainties
which could lead to the  obligor's  inadequate  capacity  to meet its  financial

                                       65
<PAGE>

commitments on the obligation.  C. A short-term  obligation rated C is currently
vulnerable to nonpayment and is dependent upon favorable business, financial and
economic  conditions  for the obligor to meet its  financial  commitment  on the
obligation.  D. A short-term  obligation  rated D is in payment  default.  The D
rating  category is used when payments on an obligation are not made on the date
due even if the  applicable  grace period has not  expired,  unless S&P believes
that such payments will be made during such grace period. The D rating also will
be used upon the  filing of a  bankruptcy  petition  or the  taking of a similar
action if payments on an obligation are jeopardized.
