                     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 its board without shareholder  approval.  As with other mutual funds,
there is no assurance that a fund will achieve its investment objective.

      U.S.  GOVERNMENT INCOME FUND AND LOW DURATION FUND. U.S. Government Income
Fund's  investment   objective  is  high  current  income  consistent  with  the
preservation of capital and liquidity.  Low Duration Fund's investment objective
is to achieve the highest level of income  consistent  with the  preservation of
capital and low volatility of net asset value.

      Low Duration Fund seeks to limit (but not eliminate) the volatility of net
asset value by normally maintaining an overall portfolio duration between one to
three years. U.S. Government Income Fund has no fixed portfolio duration policy.
"Duration"  is a measure of the expected  life of a fixed  income  security on a
present value basis and thus is a measure of interest rate risk.

      Each  fund  normally  invests  at least  65% of its  total  assets in U.S.
government   bonds   (including   mortgage-backed   securities)  and  repurchase
agreements  with  respect  to them.  Each fund may invest up to 35% of its total
assets in privately issued mortgage-backed and asset-backed  securities that, at
the time of  purchase,  are rated in the highest  rating  category by Standard &
Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"), Moody's Investors
Service,  Inc.  ("Moody's") or another nationally or internationally  recognized
statistical rating organization ("rating agency") or, if unrated, are considered
to be of comparable  quality by Mitchell Hutchins or, for Low Duration Fund, the
sub-adviser.

      Each fund has a fundamental policy of normally  concentrating at least 25%
of its total  assets in U.S.  government  and  privately  issued  mortgage-  and
asset-backed  securities.  This policy has the effect of increasing  each fund's
exposure  to the risks of these  securities  and might  cause a fund's net asset
value to  fluctuate  more  than  otherwise  would  be the  case.  Some  types of
mortgage-backed  securities,  including  "interest  only,"  "principal only" and
inverse floating classes of these securities,  can be extremely volatile and may
become  illiquid.  Low  Duration  Fund  does  not  invest  in these  classes  of
mortgage-backed securities.

      Each  fund  normally   invests  at  least  65%  of  its  total  assets  in
income-producing securities, which may include zero coupon bonds, other original
issue discount securities and (for U.S.  Government Income Fund)  principal-only
mortgage-backed securities.

      U.S.  Government  Income  Fund may  invest up to 10% of its net  assets in
illiquid securities. Low Duration Fund may invest up to 15% of its net assets in
illiquid  securities.  Each 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.  Each fund may purchase  securities  on a  when-issued  or delayed
delivery  basis.  Each fund may engage in dollar  rolls and  reverse  repurchase
agreements,  which are  considered  borrowings and may not exceed 33-1/3% of its
total assets. Each fund may also borrow for temporary or emergency purposes, but
not in excess of an additional  5% of its total assets.  Each fund may invest in
the  securities of other  investment  companies and may sell short  "against the
box."

      INVESTMENT  GRADE INCOME  FUND'S  investment  objective is to provide high
current income  consistent with the  preservation of capital and liquidity.  The
fund normally  invests at least 65% of its total assets in U.S.  government  and
investment grade corporate bonds, including mortgage-backed securities and money
market  instruments.  The fund's  investments  in money market  instruments  may
include  repurchase  agreements and commercial  paper or variable  amount master
notes whose  issuers,  at the time the security is  purchased by the fund,  have
outstanding  either  long-term bonds that are rated  investment  grade by S&P or
Moody's or  commercial  paper  rated in the  highest  rating  category by S&P or
Moody's. The fund also may invest up to 35% of its total assets in (1) corporate
bonds that are below  investment  grade, (2) preferred  stocks,  (3) convertible
securities  and  (4)   asset-backed   securities   other  than   mortgage-backed
securities.

      Investment  Grade  Income  Fund's  ability  to  invest  in  mortgage-  and
asset-backed  securities  is  limited.  The fund may  invest in  mortgage-backed
securities only if they are U.S.  government  issued or guaranteed or if, at the
time of purchase, they are investment grade. The fund may invest in asset-backed
securities  only if, at the time of  purchase,  they are rated in one of the two
highest rating categories by S&P or Moody's.  Also, the fund may not invest more
than 10% of its total  assets in interest  only and  principal  only  classes of
mortgage-backed securities.


                                       2

      Up to 20% of Investment  Grade Income Fund's net assets may be invested in
certain foreign securities. These are (1) U.S. dollar-denominated  securities of
foreign issuers or of foreign branches of U.S. banks that are traded in the U.S.
securities markets and (2) securities that are U.S. dollar-denominated but whose
value is linked to the value of foreign currencies.

      Investment  Grade Income Fund  normally  invests at least 65% of its total
assets in  income-producing  securities,  which may include  zero coupon  bonds,
other  original  issue  discount  securities,   payment-in-kind  securities  and
principal only mortgage-backed  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.

      Investment  Grade  Income  Fund 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  FUND'S  investment  objective is to provide high income.  The
fund  normally  invests at least 65% of its total  assets in high yield,  income
producing  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  Fund'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  Fund'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  Fund  normally  invests at least 65% of its total  assets in
income-producing securities, which may include zero coupon bonds, other original
issue  discount  securities,   payment-in-kind  securities  and  principal  only
mortgage backed 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  Fund 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."

      STRATEGIC INCOME FUND'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 Fund 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 Fund 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



                                       3
<PAGE>
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 its 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 Fund's strategy of sector
allocation  should be less risky than  investing  in only one sector of the bond
market.  Data from the Lehman  Aggregate Bond Index,  the Salomon  Brothers High
Yield Index,  the Merrill Lynch High Yield Index and the Salomon  Brothers World
Government Bond Index indicate that these sectors are not closely correlated. If
successful,  the fund's  strategy  should enable it to achieve a higher level of
investment  return than if it invested  exclusively in any one investment sector
or allocated a fixed proportion of its assets to each investment sector.

      Strategic  Income  Fund  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.

      Strategic Income Fund normally invests at least 65% of its total assets in
income-producing securities, which may include 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  Fund 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,  which are  considered  borrowings and may not exceed 33-1/3% of its
total assets. The fund may also borrow for temporary or emergency purposes,  but
not in excess of an additional  5% 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  Statement  of  Additional
Information,  the funds have established no policy  limitations on their ability
to use the investments or techniques discussed in these documents.

      BONDS  are  fixed or  variable  rate debt  obligations,  including  notes,
debentures,  and similar  instruments  and  securities  and various money market
instruments.  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.

      Bonds are subject to interest  rate risk and credit  risk,  but to varying
degrees.  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,  or that a market  may become  less  confident  as to the  issuer's
ability or  willingness  to do so.  Credit risk can be affected by many factors,
including adverse changes in the issuer's own financial condition or in economic
conditions.

      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 depository  receipts.  Common stocks are the
most  familiar type of equity  security.  They  represent an equity  (ownership)
interest in a corporation.

      Preferred  stock has certain fixed income  features,  like a bond,  but is
actually equity in a company, like common stock.  Convertible securities include
debentures, notes and preferred equity securities, that may be converted into or
exchanged  for a  prescribed  amount of common  stock of the same or a different

                                       4
<PAGE>

issuer  within a  particular  period of time at a  specified  price or  formula.
Depository  receipts  typically  are  issued  by banks or  trust  companies  and
evidence ownership of underlying equity securities.

      The prices of equity  securities  generally  fluctuate more than bonds 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.

      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 Statement
of  Additional  Information.  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 ratings  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 a
bond's  rating.  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 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 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.

      High yield bonds (commonly known as "junk bonds") are non-investment grade
bonds.  This  means they are rated Ba or lower by  Moody's,  BB or lower by S&P,
comparably rated by another rating agency or 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 higher 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 response to changes in
interest  rates.  During periods of economic  downturn or rising interest rates,
highly leveraged  issuers may experience  financial stress which 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.

                                       5
<PAGE>

      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
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.

      Treasury  inflation-protected  securities  ("TIPS") 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.

      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
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
purpose  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 and vice versa.

      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 (for Low Duration Fund) the sub-adviser seeks to manage the
funds' investments in mortgage-backed  securities so that the volatility of each
fund's 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,  "--
Duration." If Mitchell Hutchins or the 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 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,

                                       7
<PAGE>

consistent  with their  investment  limitations,  the funds  expect to invest in
those new types of  mortgage-backed  securities  that  Mitchell  Hutchins or the
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.  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  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 "--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 (such collateral  collectively being
called "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

                                       8
<PAGE>

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


                                    8a
<PAGE>

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
related 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
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 traditional  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

                                       9
<PAGE>

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



                                    9a
<PAGE>
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  are  mortgage-backed
securities  (sometimes  referred to as "ARMs") 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 adjustable rate mortgage 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  adjustable  rate mortgage  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.  If a monthly  payment is not sufficient to pay the interest
accruing on the adjustable  rate mortgage,  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  adjustable  rate
mortgage  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.

      Adjustable  rate  mortgage  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 these mortgage loans could
increase  because  the  availability  of fixed  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 adjustable
rate mortgage  loans might  decrease.  The rate of  prepayments  with respect to
adjustable rate mortgage loans has fluctuated in recent years.

                                       10
<PAGE>

      The rates of interest  payable on certain  adjustable rate mortgage 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 adjustable rate
mortgage  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

                                    10a
<PAGE>

on monthly or other periodic changes in interest rates or monthly payments.

      INVESTING IN FOREIGN SECURITIES.  Investing in foreign securities involves
more risks than investing in the United States.  The value of foreign securities
is subject to economic and political  developments  in the  countries  where the
companies  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 have begun using the Euro as a common
currency unit,  individual  national  economies may be adversely affected by the
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.  Transactions in foreign securities may
be subject to less efficient  settlement  practices.  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.  Additionally,
the costs of  investing  outside the United  States  frequently  are higher than
those in the United  States.  These costs  include  relatively  higher  costs to
execute trades and foreign custody expenses.

      Securities of foreign  issuers may not be registered  with the  Securities
and Exchange Commission  ("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 the funds 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.

      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.  Such  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,

                                       11

devaluation or other political or economic  developments  inside and outside the
United States.

      Each fund values its assets  daily in U.S.  dollars and does not intend to
convert its  holdings of foreign  currencies  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  value of the  assets of a fund as  measured  in U.S.  dollars  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.  Each fund
conducts its currency exchange  transactions either on a spot (i.e., cash) basis

                                    11a

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.

SPECIAL CHARACTERISTICS OF EMERGING MARKET SECURITIES AND SOVEREIGN DEBT

      EMERGING  MARKET  INVESTMENTS.  The special  risks of investing in foreign
securities are heightened when emerging markets are involved.  For example, many
emerging market currencies  recently have experienced  significant  devaluations
relative to the U.S. dollar.  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
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
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  could be subject to federal
income and 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. In such case, it would become subject
to federal income tax on all of its net income and gains. To avoid these adverse
consequences,  the fund might be required to distribute amounts that are 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 such distributions, and its current
income and the value of its shares might ultimately be reduced as a result.

      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,

                                       12
<PAGE>

among other things,  the following:  (i)  authoritarian  governments or military
involvement in political and economic decision making, and changes in government
through  extra-constitutional means; (ii) popular unrest associated with demands
for  improved  political,   economic  and  social  conditions;   (iii)  internal
insurgencies; (iv) hostile relations with neighboring countries; and (v) 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
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.

      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


                                    12a

<PAGE>

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/or to
pay 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
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.

                                       13
<PAGE>

      The occurrence of political,  social or diplomatic  changes in one or more
of the  countries  issuing  sovereign  debt  could  adversely  affect the funds'
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 the funds'  portfolios are managed 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.

   
                                 13a
<PAGE>

      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 debt  securities  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 have been issued only in recent years,  and accordingly 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 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.

                                       14
<PAGE>

      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 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  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,



                                    14a
<PAGE>

payment priorities and interest rate provisions,  and the extent of the payments
made with respect to structured  foreign  investments is 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 that  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
currencies. A fund may experience loss of principal due to these adjustments.

      ZERO  COUPON  AND  OTHER  OID  SECURITIES;  PIK  SECURITIES.  Zero  coupon
securities  are securities on which no periodic  interest  payments are made but
instead are sold at a deep  discount  from their face 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 debt securities and
sell the principal and the coupons separately.


                                       15
<PAGE>

      The funds may invest in other  securities  with  original  issue  discount
("OID"),  a term that means the securities  issued at a price that is lower than
their value at maturity,  even though the securities also may make cash payments
of interest 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 debt  securities of
comparable maturities that make current distributions of interest in cash.

      Federal  tax law  requires  that the holder of a zero  coupon or other OID
security  include in gross income each year the OID that accrues on the security
for the year,  even  though  the  holder  receives  no  interest  payment on the
security  during the year.  Similarly,  while PIK securities may pay interest in
the form of  additional  securities  rather  than cash,  that  interest  must be
included in a fund's current income.  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 such 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  coupons 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. As
long as the SEC takes  this  position,  CATS and  TIGRs,  which  are not  issued
through the U.S. Treasury, will not be counted as U.S. government securities for
purposes of the 65% investment  requirement applicable to U.S. Government Income
Fund and Low Duration Fund.

      CONVERTIBLE SECURITIES.  A convertible security is a bond, preferred stock
or other  security  that 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. 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.


                                    15a
<PAGE>

      Before conversion,  convertible securities have characteristics similar to
non-convertible  debt securities in that they ordinarily provide a stable stream
of income with  generally  higher yields than those of common stocks of the same
or similar  issuers.  Convertible  securities  rank senior to common  stock in a
corporation's  capital  structure  but are usually  subordinated  to  comparable
non-convertible securities. The value of a convertible security is a function of
its "investment  value"  (determined by its yield  comparison with the yields of
other  securities  of  comparable  maturity  and  quality  that  do  not  have a
conversion  privilege) and its  "conversion  value" (the  security's  worth,  at
market value,  if converted  into the underlying  common stock).  The investment
value of a convertible security is influenced by changes in interest rates, with
investment value declining as interest rates increase and increasing as interest
rates decline. The credit standing of the issuer and other factors also may have
an effect on the convertible  security's  investment value. The conversion value
of a convertible  security is  determined by the market price of the  underlying
common stock. If the conversion  value is low relative to the investment  value,
the price of the convertible  security is governed principally by its investment
value.  Generally,  the conversion  value decreases as the convertible  security
approaches  maturity.  To the extent the market price of the  underlying  common
stock  approaches or exceeds the conversion  price, the price of the convertible
security will be increasingly influenced by its conversion value. In addition, a
convertible  security generally will sell at a premium over its conversion value
determined by the extent to which  investors place value on the right to acquire
the underlying common stock while holding 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.  Investment
Grade  Income  Fund has no  current  intention  of  converting  any  convertible
securities  it may own into equity or holding  them as equity  upon  conversion,
although it may do so for temporary purposes. The other funds that may invest in
convertible  securities  may  hold  any  equity  securities  they  acquire  upon
conversion subject only to their limitations on holding equity securities.

      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
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.


<PAGE>

      Assignments  and  Participations  are generally not  registered  under the
Securities Act of 1933, as amended  ("Securities Act of 1933"),  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 or as
part of its normal investment  program.  Such investments  include,  among other
things, (1) securities issued or guaranteed by the U.S. government or one of its
agencies or instrumentalities, (2) commercial paper rated at least A-1 by S&P or
P-1 by Moody's (Low Duration Fund and  Investment  Grade Income Fund) or without
regard  to  rating  (High  Income  Fund and  Strategic  Income  Fund),  (3) bank
certificates  of deposit,  bankers'  acceptances  and (4) repurchase  agreements
secured by any of the foregoing. The money market instruments of U.S. Government
Income Fund will be limited to obligations of the U.S. government,  its agencies
or instrumentalities or repurchase agreements secured by such obligations.

      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 Statement of Additional  Information 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 (for Low Duration Fund) the sub-adviser has determined are
liquid pursuant to guidelines  established by each fund's board. The assets used
as cover for  over-the-counter  options  written by the funds will be considered
illiquid unless the  over-the-counter  options are sold to qualified dealers who
agree that the funds may repurchase any over-the-counter options they write 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,  IO and PO  classes  of  mortgage-backed  securities  generally  are
considered  illiquid.  However, IO and PO 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
sub-adviser   has  determined  that  they  are  liquid  pursuant  to  guidelines
established  by each  fund's  board.  To the extent a fund  invests in  illiquid
securities,  it may not be able to readily  liquidate such  investments  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 of 1933
and may be sold only in privately  negotiated or other exempted  transactions or
after a  registration  statement  under the  Securities  Act of 1933 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.

      However,  not all restricted  securities are illiquid.  To the extent that
foreign  securities  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 of 1933.  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 of 1933 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 such portfolio
securities,  and the fund might be unable to dispose of such securities promptly
or at favorable prices.

                                    17
<PAGE>

      Each board has delegated the function of making day-to-day  determinations
of liquidity to Mitchell Hutchins or the sub-adviser, as applicable, 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 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 applicable board.

    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



                                    17a
<PAGE>

"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 sub-adviser to present minimum
credit risks in accordance with guidelines established by the fund's board.

      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 and
securities dealers. 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.

      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, such 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.

      DOLLAR  ROLLS.  In a dollar  roll, a fund sells  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.

      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 or by the fund later than
the normal  settlement  date for such  securities  at a stated  price and yield.
When-issued securities include TBA ("to be assigned") 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  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. Depending
on  market  conditions,  a fund's  when-issued  and  delayed  delivery  purchase
commitments  could  cause  its net asset  value  per share to be more  volatile,
because  such  securities  may  increase  the amount by which the  fund's  total
assets,  including the value of when-issued and delayed delivery securities held
by that fund, exceeds its net assets.


                                    18
<PAGE>

      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 may sell the right to acquire the
security  prior  to  delivery  if  Mitchell  Hutchins  or  the  sub-adviser,  as
applicable,  deems it  advantageous to do so, which may result in a gain or loss
to the fund.

      DURATION. Duration is a measure of the expected life of a debt security on
a present value basis.  Duration  incorporates the debt security's yield, coupon
interest payments,  final maturity and call features into one measure and is one
of the fundamental  tools used by Mitchell  Hutchins and (for Low Duration Fund)
the sub-adviser in portfolio  selection and yield curve positioning for a fund's
bond  investments.  Duration was developed as a more precise  alternative to the
concept "term to maturity." Traditionally,  a debt security's "term to maturity"
has been used as a proxy for the sensitivity of the security's  price to changes
in interest  rates (which is the  "interest  rate risk" or  "volatility"  of the
security).  However,  "term to  maturity"  measures  only the time  until a debt


                                    18a
<PAGE>

security  provides for a final payment,  taking no account of the pattern of the
security's 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 debt  security,  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
debt  security  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 and the  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 debt securities.  For example,  when
the level of interest rates  increases by 1%, a debt security  having a positive
duration of three years  generally will decrease by  approximately  3%. Thus, if
Mitchell  Hutchins  or the  sub-adviser  calculates  the  duration  of a  fund's
portfolio  of debt  securities  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
debt  securities  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.

      There are some situations in which the standard duration  calculation does
not properly  reflect the  interest  rate  exposure of a security.  For example,
floating and variable rate securities 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
and the  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 securities 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 that 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


                                       19
<PAGE>

investments or other short-term liquid  investments.  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 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  boards  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.

                                    19a
<PAGE>

      SHORT  SALES  "AGAINST  THE BOX." Each fund 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 (for Low Duration Fund) the 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 or reverse
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, 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.



                                    20
<PAGE>

      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,  and except that U.S.
Government Income Fund and Low Duration Fund, under normal  circumstances,  each
will  invest  25% or more of its total  assets  in  mortgage-  and  asset-backed
securities,  which  (whether  or  not  issued  or  guaranteed  by an  agency  or
instrumentality  of the U.S.  government)  shall be considered a single industry
for purposes of this limitation.

      (2) issue senior securities or borrow money, except as permitted under the
Investment  Company Act of 1940, as amended  ("Investment  Company Act of 1940")
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 debt  securities 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.

      (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.


                                    20a
<PAGE>

      (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.

      In addition,  U.S.  Government Income Fund, Low Duration Fund,  Investment
Grade Income Fund and High Income Fund will not:

      (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 appropriate board without
shareholder approval.

      Each fund will not:

      (1)  invest  more than 10% of its net  assets  (15% of net  assets for Low
Duration Fund and Strategic Income Fund) in illiquid securities.


                                    21
<PAGE>

      (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.

      (5)  purchase  securities  of other  investment  companies,  except to the
extent  permitted  by the  Investment  Company  Act of 1940 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  (and  except  that a fund will not  purchase  securities  of  registered
open-end  investment  companies or registered unit investment trusts in reliance
on Sections 12(d)(1)(F) or 12(d)(1)(G) of the Investment Company Act of 1940).

                     STRATEGIES USING DERIVATIVE INSTRUMENTS

      GENERAL DESCRIPTION OF DERIVATIVE INSTRUMENTS.  Mitchell Hutchins and (for
Low Duration Fund) the  sub-adviser  may use a variety of financial  instruments
("Derivative   Instruments"),   including  certain  options,  futures  contracts
(sometimes  referred  to as  "futures")  and  options on futures  contracts,  to
attempt to hedge each fund's  portfolio  and also to attempt to enhance  income,
realize gains or manage the duration of its portfolio.  Each fund also may enter
into interest rate swap transactions. High Income Fund and Strategic Income Fund
also may use forward currency  contracts for hedging purposes.  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,


                                    21a
<PAGE>

however,  each fund's use of these instruments will place at risk a much smaller
portion  of its  assets.  In  particular,  each  fund  may  use  the  Derivative
Instruments described below.

      The funds might not use any  derivative  instruments  or  strategies,  and
there can be no assurance that using any strategy will succeed.  If the Mitchell
Hutchins or the  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 debt  securities  or  currency,  in most  cases the
contracts are closed out before the settlement date without the making or taking
of delivery.

                                    22
<PAGE>

      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.  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



                                    22a
<PAGE>

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  transaction  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 the  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 the  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  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 debt securities 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.  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).



                                 23

<PAGE>

      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-adviser may discover  additional
opportunities in connection with Derivative Instruments and with hedging, income
and gain strategies.  These new opportunities may become available as regulatory
authorities  broaden the range of permitted  transactions  and as new Derivative
Instruments and techniques are developed.  Mitchell  Hutchins or the sub-adviser
may  utilize  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 funds'  Prospectus or
Statement of Additional  Information 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  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-adviser 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.



                                    23a
<PAGE>

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 the 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 such  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.

                                    24

    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  and  (for  High  Income  Fund and  Strategic  Income  Fund) 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.  A fund may also use options
to attempt to 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'  Investments,
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  options  on  bonds  are
European-style  options.  This  means  that the  option  can  only be  exercised
immediately  prior to its  expiration.  This is in  contract  to  American-style
options that may be exercised at any time. There are also other types of options
that may be exercised on certain specified dates before expiration. Options that
expire unexercised have no value.

                                       24a

      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.  Exchange markets for options on debt securities 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 which, 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.

      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 use of options is governed by the
following  guidelines,  which  can be  changed  by  each  fund's  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  and interest rate futures  contracts.  High Income Fund and Strategic
Income Fund also may purchase and sell foreign  currency  futures  contracts.  A
fund may 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.

                                       25
<PAGE>

      Futures  strategies  also can be used to manage the average  duration of a
fund's  portfolio.   If  Mitchell  Hutchins  or  (for  Low  Duration  Fund)  the
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

                                    25a

<PAGE>

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
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.

                                       26
<PAGE>

      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 a fund's board without shareholder vote:

      (1) To the extent a fund  enters  into  futures  contracts  and options on
futures positions that are not for bona fide hedging purposes (as defined by the
CFTC), the aggregate  initial margin and premiums on those positions  (excluding
the amount by which  options  are  "in-the-money")  may not exceed 5% of its 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 each 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 each fund will not exceed 5% of its total assets.

      FOREIGN CURRENCY HEDGING STRATEGIES--SPECIAL  CONSIDERATIONS.  High Income
Fund  and  Strategic  Income  Fund  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.  Such 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.
Such 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  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  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.

                                       27
<PAGE>


      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. High Income Fund and Strategic Income Fund 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.


                                    27a
<PAGE>

      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.

      As is the case with  futures  contracts,  holders  and  writers of forward
currency  contracts can enter into offsetting closing  transactions,  similar to
closing  transactions  on futures,  by selling or purchasing,  respectively,  an
instrument  identical to the  instrument  purchased or sold.  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. High Income Fund and
Strategic  Income Fund 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.  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.


                                    28
<PAGE>

      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 only use  these  transactions  as a hedge  and not as a
speculative  investment.  Interest rate swap  transactions  are subject to risks
comparable to those described above with respect to other hedging strategies.

      A fund may enter into  interest  rate swaps,  caps,  floors and collars on
either an  asset-based  or  liability-based  basis,  depending  on whether it is
hedging its assets or its liabilities, and 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. Inasmuch as these interest rate swap transactions are entered into for
good faith  hedging  purposes,  and  inasmuch  as  segregated  accounts  will be
established with respect to such  transactions,  Mitchell  Hutchins and (for Low
Duration Fund) the sub-adviser 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 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 into swap  transactions  only with banks and  recognized
securities  dealers believed by Mitchell  Hutchins or the 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



                                 28a
<PAGE>

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.

      Board members are compensated as follows:

      o     MANAGED TRUST has  seven operating series  and pays each trustee who
            is not an "interested  person" of the Trust $1,000 annually for each
            series.  Therefore,  Managed  Trust  pays each such  trustee  $7,000
            annually,  plus any  additional  amounts due for board or  committee
            meetings.

      o     SECURITIES TRUST has two operating series and pays each board member
            who is not an "interested  person" of the Trust $1,000  annually for
            Strategic  Income Fund and an  additional  $1,500  annually  for its
            second  series.  Therefore,  Securities  Trust  pays each such board
            member $2,500 annually, plus any additional amounts due for board or
            committee meetings.

      Each Trust pays up to $150 per  series  for each  board  meeting  and each
separate meeting of a board  committee.  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. Board members and officers own in the aggregate less than 1%
of the  outstanding  shares  of any  class of each  fund.  Because  PaineWebber,
Mitchell   Hutchins  and  (for  Low  Duration  Fund)  the  sub-adviser   perform
substantially  all the services  necessary  for the  operation of the Trusts and
each fund, the Trusts require no employees. No officer,  director or employee of
Mitchell  Hutchins or PaineWebber  presently  receives any compensation from the
Trust for acting as a board member or officer.

      PERSONAL  TRADING  POLICIES.  Mitchell  Hutchins  personnel  may invest in
securities  for their own accounts  pursuant to a code of ethics that  describes
the fiduciary duty owed to  shareholders  of PaineWebber  mutual funds and other
Mitchell  Hutchins  advisory  accounts  by  all  Mitchell  Hutchins'  directors,
officers  and  employees,  establishes  procedures  for personal  investing  and
restricts certain transactions. For example, employee accounts generally must be
maintained  at  PaineWebber,   personal   trades  in  most  securities   require
pre-clearance  and  short-term  trading  and  participation  in  initial  public
offerings  generally  are  prohibited.  In  addition,  the code of  ethics  puts
restrictions  on the  timing of  personal  investing  in  relation  to trades by
PaineWebber Funds and other Mitchell Hutchins advisory clients. Personnel of the
sub-adviser  may also invest in  securities  for their own accounts  pursuant to
comparable codes of ethics.

      DISTRIBUTION  ARRANGEMENTS.  Mitchell  Hutchins acts as the distributor of
each class of shares of each fund under  separate  distribution  contracts  with
each Trust (collectively,  "Distribution Contracts"). Each Distribution Contract
requires  Mitchell  Hutchins to use its best efforts,  consistent with its other
businesses,  to sell  shares  of the  applicable  fund.  Shares of each fund are
offered  continuously.   Under  separate  exclusive  dealer  agreements  between
Mitchell Hutchins and PaineWebber  relating to each class of shares of the funds
(collectively, "Exclusive Dealer Agreements"), PaineWebber and its correspondent
firms sell each fund's shares.

      Under  separate plans of  distribution  pertaining to the Class A, Class B
and Class C shares of each fund  adopted by each Trust in the manner  prescribed
under Rule 12b-1 under the Investment Company Act of 1940 (each, respectively, a
"Class A Plan," "Class B Plan" and "Class C Plan," and  collectively,  "Plans"),
each fund pays  Mitchell  Hutchins  a service  fee,  accrued  daily and  payable
monthly,  at the annual  rate of 0.25% of the  average  daily net assets of each
class of  shares.  Under the Class B Plan,  each fund pays  Mitchell  Hutchins a
distribution fee, accrued daily and payable monthly, at the annual rate of 0.75%
of the average  daily net assets of the Class B shares.  Under the Class C Plan,
each fund pays Mitchell  Hutchins a distribution  fee, accrued daily and payable
monthly,  at the  annual  rate of 0.50% of the  average  daily net assets of the
Class C shares. There is no distribution plan with respect to the funds' Class Y
shares.

      Mitchell Hutchins uses the service fees under the Plans for Class A, B and
C shares  primarily to pay PaineWebber for shareholder  servicing,  currently at
the annual rate of 0.25% of the aggregate  investment amounts maintained in each
fund by PaineWebber clients. PaineWebber then compensates its Financial Advisors
for  shareholder  servicing  that they  perform and offsets its own  expenses in
servicing and maintaining shareholder accounts.

      Mitchell Hutchins uses the distribution fees under the Class B and Class C
Plans to:

      o     Offset  the  commissions it  pays to  PaineWebber  for  selling each
            fund's Class B and Class C shares, respectively.

      o     Offset  each fund's  marketing  costs attributable  to such classes,
            such as  preparation, printing and distribution of sales literature,
            advertising  and prospectuses to  prospective investors  and related
            overhead expenses, such as employee salaries and bonuses.

      PaineWebber compensates Financial Advisors when Class B and Class C shares
are bought by  investors,  as well as on an  ongoing  basis.  Mitchell  Hutchins
receives no special  compensation from any of the funds or investors at the time
Class B or C shares are bought.


                                       38
<PAGE>

      Mitchell  Hutchins  receives the proceeds of the initial sales charge paid
when Class A shares are bought and of the contingent  deferred sales charge paid
upon sales of shares. These proceeds may be used to cover distribution expenses.

      The Plans and the related Distribution  Contracts for Class A, Class B and
Class C shares specify that each fund must pay service and distribution  fees to
Mitchell Hutchins for its activities, not as reimbursement for specific expenses
incurred.  Therefore,  even if Mitchell Hutchins' expenses exceed the service or
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
service and  distribution  fees received or accrued through the termination date
of any Plan will be Mitchell  Hutchins' sole  responsibility and not that of the
funds. Annually, the board of each fund reviews the Plans and Mitchell Hutchins'
corresponding  expenses for each class separately from the Plans and expenses of
the other classes.

      Among other things,  each Plan  provides  that (1) Mitchell  Hutchins will
submit to the applicable  board at least  quarterly,  and the board members will
review,  reports  regarding all amounts expended under the Plan and the purposes
for which such expenditures were made, (2) the Plan will continue in effect only
so long as it is approved at least annually,  and any material amendment thereto
is approved, by the applicable 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 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 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.

      In  reporting  amounts  expended  under the  Plans to the  board  members,
Mitchell Hutchins allocates  expenses  attributable to the sale of each class of
each  fund's  shares to such class based on the ratio of sales of shares of such
class to the sales of all three classes of shares. The fees paid by one class of
a fund's  shares  will not be used to  subsidize  the sale of any other class of
fund shares.

      The funds paid (or accrued) the following service and/or distribution fees
to  Mitchell  Hutchins  under the Class A, Class B and Class C Plans  during the
fiscal year ended November 30, 1998:

      "Marketing and  advertising"  includes various internal costs allocated by
Mitchell  Hutchins  to its  efforts at  distributing  the funds'  shares.  These
internal costs encompass  office rent,  salaries and other overhead  expenses of
various  departments  and areas of  operations  of  Mitchell  Hutchins.  "Branch
network costs allocated and interest expense" consist of an allocated portion of
the expenses of various PaineWebber  departments involved in the distribution of
the funds' shares, including the PaineWebber retail branch system.

      In  approving   each  fund's   overall   Flexible   PricingSM   system  of
distribution,  the applicable board considered  several factors,  including that
implementation  of Flexible  Pricing  would (1) enable  investors  to choose the
purchasing option best suited to their individual situation, thereby encouraging
current  shareholders to make additional  investments in the fund and attracting
new  investors  and  assets  to the  fund to the  benefit  of the  fund  and its
shareholders,  (2) facilitate distribution of the fund's shares and (3) maintain
the  competitive  position  of the fund in  relation  to other  funds  that have
implemented or are seeking to implement similar distribution arrangements.

      In approving the Class A Plan,  each board  considered all the features of
the distribution system,  including (1) the conditions under which initial sales
charges would be imposed and the amount of such charges,  (2) Mitchell Hutchins'
belief  that the  initial  sales  charge  combined  with a service  fee would be
attractive to PaineWebber Financial Advisors and correspondent firms,  resulting
in  greater  growth  of the fund  than  might  otherwise  be the  case,  (3) the
advantages to the  shareholders  of economies of scale  resulting from growth in
the fund's assets and potential  continued growth,  (4) the services provided to


                                       40
<PAGE>

the fund and its shareholders by Mitchell Hutchins, (5) the services provided by
PaineWebber  pursuant to its Exclusive Dealer  Agreement with Mitchell  Hutchins
and (6) Mitchell Hutchins' shareholder service-related expenses and costs.

      In approving the Class B Plan,  the board of each fund  considered all the
features of the  distribution  system,  including (1) the conditions under which
contingent  deferred  sales  charges  would be  imposed  and the  amount of such
charges,  (2) the  advantage  to investors  in having no initial  sales  charges
deducted  from fund  purchase  payments and instead  having the entire amount of
their  purchase  payments  immediately  invested in fund  shares,  (3)  Mitchell
Hutchins'  belief  that  the  ability  of  PaineWebber  Financial  Advisors  and
correspondent  firms to receive sales  commissions  when Class B shares are sold
and continuing service fees thereafter while their customers invest their entire
purchase  payments  immediately in Class B shares would prove  attractive to the
Financial Advisors and correspondent  firms,  resulting in greater growth of the
fund than might otherwise be the case, (4) the advantages to the shareholders of
economies  of scale  resulting  from growth in the fund's  assets and  potential
continued growth,  (5) the services provided to the fund and its shareholders by
Mitchell  Hutchins,  (6) the services  provided by  PaineWebber  pursuant to its
Exclusive  Dealer  Agreement with Mitchell  Hutchins and (7) Mitchell  Hutchins'
shareholder  service- and  distribution-related  expenses  and costs.  The board
members also  recognized  that  Mitchell  Hutchins'  willingness  to  compensate
PaineWebber  and its  Financial  Advisors,  without the  concomitant  receipt by
Mitchell Hutchins of initial sales charges, was conditioned upon its expectation
of being compensated under the Class B Plan.

      In approving the Class C Plan,  each board  considered all the features of
the distribution  system,  including (1) the advantage to investors in having no
initial sales charges  deducted from fund purchase  payments and instead  having
the  entire  amount of their  purchase  payments  immediately  invested  in fund
shares,  (2) the advantage to investors in being free from  contingent  deferred
sales charges upon  redemption for shares held more than one year and paying for
distribution on an ongoing basis, (3) Mitchell Hutchins' belief that the ability
of  PaineWebber  Financial  Advisors and  correspondent  firms to receive  sales
compensation  for their sales of Class C shares on an ongoing basis,  along with
continuing  service fees,  while their  customers  invest their entire  purchase
payments  immediately  in Class C shares and  generally  do not face  contingent
deferred sales  charges,  would prove  attractive to the Financial  Advisors and
correspondent  firms,  resulting  in  greater  growth  to the  fund  than  might
otherwise be the case,  (4) the advantages to the  shareholders  of economies of
scale resulting from growth in the fund's assets and potential continued growth,
(5) the services provided to the fund and its shareholders by Mitchell Hutchins,
(6) the  services  provided  by  PaineWebber  pursuant to its  Exclusive  Dealer
Agreement with Mitchell Hutchins and (7) Mitchell Hutchins' shareholder service-
and  distribution-related  expenses and costs. The board members also recognized
that Mitchell Hutchins' willingness to compensate  PaineWebber and its Financial
Advisors,  without the concomitant receipt by Mitchell Hutchins of initial sales
charges or  contingent  deferred  sales charges upon  redemption  after one year
following  purchase was conditioned  upon its  expectation of being  compensated
under the Class C Plan.

      With respect to each Plan,  the boards  considered all  compensation  that
Mitchell  Hutchins would receive under the Plan and the  Distribution  Contract,
including service fees and, as applicable,  initial sales charges,  distribution
fees and  contingent  deferred  sales  charges.  The boards also  considered the
benefits that would accrue to Mitchell Hutchins under each Plan in that Mitchell
Hutchins  would  receive  service,  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 Plan were  successful  and the fund  attained  and
maintained significant asset levels.

                             PORTFOLIO TRANSACTIONS

      Subject to policies  established by each board,  Mitchell Hutchins or (for
Low Duration  Fund) the  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.
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.  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.  While
Mitchell  Hutchins and the  sub-adviser  generally seek  reasonably  competitive
commission rates, payment of the lowest commission is not necessarily consistent
with obtaining the best net results.

      During the fiscal years or periods 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,
consistent  with  the  policy  of  obtaining  the best  net  results,  brokerage
transactions  may be  conducted  through  Mitchell  Hutchins or its  affiliates,
including  PaineWebber,  or (for Low Duration Fund) brokerage  affiliates of the
sub-adviser.  Each board has adopted  procedures in  conformity  with Rule 17e-1
under  the  Investment  Company  Act  of  1940  to  ensure  that  all  brokerage
commissions  paid to PaineWebber or brokerage  affiliates of the sub-adviser are
reasonable  and fair.  Specific  provisions  in the Advisory  Contracts  and the
Sub-Advisory   Contract   authorize   Mitchell  Hutchins  and  the  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.  None of the funds paid brokerage
commissions to PaineWebber  or (for Low Duration Fund)  brokerage  affiliates of
the  sub-adviser  during the fiscal  years or periods  ended  November 30, 1998,
November 30, 1997,  November 30, 1996 or (for Strategic  Income Fund) the fiscal
year ended January 31, 1996.

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

      Consistent  with the  interests  of the funds and subject to the review of
each board,  Mitchell  Hutchins or (for Low Duration Fund) the  sub-adviser  may
cause a fund to  purchase  and sell  portfolio  securities  through  brokers who
provide Mitchell Hutchins or the sub-adviser with research, analysis, advice and
similar  services.  The funds may pay to 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,  and that the total  commissions paid by the fund will be reasonable in
relation  to the  benefits  to the fund over the long term.  For the fiscal year
ended November 30, 1998, 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:

          Strategic Income Fund............            0                  0

      For  purchases or sales with  broker-dealer  firms that act as  principal,
Mitchell  Hutchins or (for Low Duration  Fund) the  sub-adviser,  as applicable,
seeks best execution.  Although Mitchell Hutchins or the 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.
Moreover, Mitchell Hutchins and the sub-adviser will not enter into any explicit
soft dollar arrangements relating to principal transactions and will not receive


                                       43
<PAGE>

in principal transactions the types of services that could be purchased for hard
dollars.  Mitchell Hutchins or the sub-adviser may engage in agency transactions
in  over-the-counter  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.  These procedures  include Mitchell Hutchins or
the  sub-adviser  receiving  multiple  quotes from dealers before  executing the
transactions on an agency basis.

      Information and research services  furnished by brokers or dealers through
which or with  which the funds  effect  securities  transactions  may be used by
Mitchell  Hutchins or (for Low Duration Fund) the  sub-adviser in advising other
funds or accounts  and,  conversely,  research  services  furnished  to Mitchell
Hutchins or the sub-adviser by brokers or dealers in connection with other funds
or  accounts  that either of them  advises  may be used in  advising  the funds.
Information  and research  received  from brokers or dealers will be in addition
to,  and not in lieu of, the  services  required  to be  performed  by  Mitchell
Hutchins under the Advisory  Contracts or the sub-adviser under the Sub-Advisory
Contract.

      Investment  decisions for a fund and for other investment accounts managed
by Mitchell  Hutchins or (for Low  Duration  Fund) by the  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 the funds are  concerned,  or upon  their  ability to  complete  their
entire order, in other cases it is believed that coordination and the ability to
participate in volume transactions will be beneficial to the funds.

      The funds will not purchase  securities that are offered in  underwritings
in which  PaineWebber or (for Low Duration Fund) an affiliate of the sub-adviser
is a member of the underwriting or selling group,  except pursuant to procedures
adopted by each board pursuant to Rule 10f-3 under the Investment Company Act of
1940. 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 fund.

      As of  November  30,  1998,  the funds  owned  securities  issued by their
      regular broker-dealers as follows:

      Low Duration Fund had entered into a repurchase agreement transaction with
      State Street Bank and Trust Company ($2,977,000).

      Investment  Grade  Income Fund had  entered  into a  repurchase  agreement
      transaction  with Bear Stearns Co. Inc.  ($12,000,000)  and Morgan Stanley
      Dean Witter & Co. ($11,497,000).

      High Income Fund had entered  into a  repurchase  agreement  with  Societe
      Generale ($14,632,000).

      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:

            REDUCED SALES CHARGES, ADDITIONAL EXCHANGE AND REDEMPTION
                         INFORMATION AND OTHER SERVICES

      WAIVERS  OF SALES  CHARGES/CONTINGENT  DEFERRED  SALES  CHARGES -- CLASS A
SHARES. The following  additional sales charge waivers are available for Class A
shares if you:

      o  Purchase shares through a variable annuity offered only to qualified
         plans. For investments made pursuant to this waiver, Mitchell Hutchins
         may make payments out of its own resources to PaineWebber and to the
         variable annuity's sponsor, adviser or distributor in a total amount
         not to exceed l% of the amount invested;

      o  Acquire shares through an investment program that is not sponsored by 
         PaineWebber or its affiliates and that charges participants a fee for
         program services, provided that the program sponsor has entered into a
         written agreement with PaineWebber permitting the sale of shares at net
         asset value to that program. For investments made pursuant to this
         waiver, Mitchell Hutchins may make a payment to PaineWebber out of its
         own resources in an amount not to exceed 1% of the amount invested. For
         subsequent investments or exchanges made to implement a rebalancing
         feature of such an investment program, the minimum subsequent
         investment requirement is also waived;

      o  Acquire shares in connection with a reorganization pursuant to which a
         fund acquires substantially all of the assets and liabilities of
         another fund in exchange solely for shares of the acquiring fund; or

      o  Acquire shares in connection with the disposition of proceeds from the
         sale of shares of Managed High Yield Plus Fund Inc. that were acquired
         during that fund's initial public offering of shares and that meet
         certain other conditions described in its prospectus

      In addition, reduced sales charges on Class A shares are available through
the combined  purchase plan or through rights of accumulation  described  below.
Class A share  purchases  of $1  million  or more are not  subject to an initial
sales charge; however, if a shareholder sells these shares within one year after
purchase,  a contingent deferred sales charge of 1% of the offering price or the
net asset value of the shares at the time of sale by the shareholder,  whichever
is less, is imposed.

      COMBINED  PURCHASE  PRIVILEGE  -- CLASS A SHARES.  Investors  and eligible
groups of related fund investors may combine  purchases of Class A shares of the
funds  with  concurrent  purchases  of Class A shares of any  other  PaineWebber
mutual fund and thus take  advantage of the reduced sales  charges  indicated in
the  tables of sales  charges  for Class A shares in the  Prospectus.  The sales
charge payable on the purchase of Class A shares of the funds and Class A shares
of such other funds will be at the rates  applicable  to the total amount of the
combined concurrent purchases.

      An  "eligible  group  of  related  fund  investors"  can  consist  of  any
combination of the following:

      (a) an individual, that individual's spouse, parents and children;

      (b) an individual and his or her individual retirement account ("IRA");

      (c) an  individual  (or  eligible  group of  individuals)  and any company
controlled  by the  individual(s)  (a person,  entity or group that holds 25% or
more of the  outstanding  voting  securities of a corporation  will be deemed to
control the  corporation,  and a partnership  will be deemed to be controlled by
each of its general partners);

      (d) an  individual  (or  eligible  group of  individuals)  and one or more
employee benefit plans of a company controlled by the individual(s);

      (e) an individual (or eligible group of  individuals)  and a trust created
by the  individual(s),  the beneficiaries of which are the individual and/or the
individual's spouse, parents or children;

      (f) an individual and a Uniform Gifts to Minors  Act/Uniform  Transfers to
Minors Act account created by the individual or the individual's spouse;


                                       45
<PAGE>

      (g) an employer (or group of related  employers) and one or more qualified
retirement  plans  of such  employer  or  employers  (an  employer  controlling,
controlled by or under common control with another employer is deemed related to
that other employer); or

      (h) individual  accounts related together under one registered  investment
adviser  having full  discretion  and control over the accounts.  The registered
investment  adviser must communicate at least quarterly  through a newsletter or
investment update establishing a relationship with all of the accounts.

      RIGHTS  OF  ACCUMULATION  -- CLASS A SHARES.  Reduced  sales  charges  are
available  through a right of  accumulation,  under which investors and eligible
groups of related fund  investors  (as defined  above) are permitted to purchase
Class A shares  of the  funds  among  related  accounts  at the  offering  price
applicable to the total of (1) the dollar amount then being  purchased  plus (2)
an amount equal to the then-current net asset value of the purchaser's  combined
holdings  of Class A fund  shares  and Class A shares  of any other  PaineWebber
mutual  fund.  The  purchaser  must  provide  sufficient  information  to permit
confirmation of his or her holdings, and the acceptance of the purchase order is
subject  to such  confirmation.  The right of  accumulation  may be  amended  or
terminated at any time.

      REINSTATEMENT PRIVILEGE -- CLASS A SHARES.  Shareholders who have redeemed
Class A shares of a fund may reinstate  their account  without a sales charge by
notifying  the  transfer  agent of such  desire and  forwarding  a check for the
amount  to be  purchased  within  365 days  after  the date of  redemption.  The
reinstatement  will be made at the net asset value per share next computed after
the notice of  reinstatement  and check are  received.  The amount of a purchase
under this  reinstatement  privilege  cannot exceed the amount of the redemption
proceeds.   Gain  on  a  redemption   is  taxable   regardless  of  whether  the
reinstatement  privilege  is  exercised,  although  a  loss  arising  out  of  a
redemption  might not be  deductible  under certain  circumstances.  See "Taxes"
below.

      WAIVERS  OF  CONTINGENT  DEFERRED  SALES  CHARGES  -- CLASS B SHARES.  The
maximum 5% contingent  deferred  sales charge (3% for Low Duration Fund) applies
to sales of shares during the first year after  purchase.  The charge  generally
declines  by 1%  annually,  reaching  zero after six years  (four  years for Low
Duration Fund). Among other circumstances,  the contingent deferred sales charge
on Class B shares is waived where a total or partial  redemption  is made within
one year following the death of the shareholder.  The contingent  deferred sales
charge waiver is available where the decedent is either the sole  shareholder or
owns  the  shares  with  his or her  spouse  as a joint  tenant  with  right  of
survivorship.  This waiver applies only to redemption of shares held at the time
of death.

      PURCHASES OF CLASS Y SHARES  THROUGH THE PACE MULTI  ADVISOR  PROGRAM.  An
investor  who  participates  in the PACE Multi  Advisor  Program is  eligible to
purchase Class Y shares.  The PACE Multi Advisor Program is an advisory  program
sponsored  by  PaineWebber  that  provides  comprehensive  investment  services,
including investor profiling,  a personalized asset allocation strategy using an
appropriate combination of funds, and a quarterly investment performance review.
Participation  in the PACE  Multi  Advisor  Program  is subject to payment of an
advisory fee at the effective  maximum annual rate of 1.5% of assets.  Employees
of PaineWebber  and its affiliates are entitled to a waiver of this fee.  Please
contact your PaineWebber Financial Advisor or PaineWebber's  correspondent firms
for more information concerning mutual funds that are available through the PACE
Multi Advisor Program.

      PURCHASES AND SALES OF CLASS Y SHARES FOR  PARTICIPANTS  IN PW 401(K) PLUS
PLAN.  The  trustee of the PW 401(k)  Plus  Plan,  a defined  contribution  plan
sponsored  by PW Group,  buys and sells Class Y shares of the funds to implement
the investment  choices of individual plan participants with respect to their PW
401(k) Plus Plan contributions.  Individual plan participants should consult the
Summary  Plan  Description  and other plan  material  of the PW 401(k) Plus Plan
(collectively,  "Plan  Documents")  for a  description  of  the  procedures  and
limitations applicable to making and changing investment choices.  Copies of the
Plan  Documents are available  from the Benefits  Connection,  100 Halfday Road,
Lincolnshire,  IL  60069  or  by  calling  1-888-PWEBBER  (1-888-793-2237).   As
described  in the Plan  Documents,  the price at which Class Y shares are bought
and sold by the  trustee  of PW 401(k)  Plus Plan might be more or less than the
price per share at the time the participants made their investment choices.

      ADDITIONAL  EXCHANGE  AND  REDEMPTION  INFORMATION.  As  discussed  in the
Prospectus,  eligible  shares of the funds may be  exchanged  for  shares of the
corresponding  class of most other PaineWebber  mutual funds. Class Y shares are
not eligible for exchange. Shareholders will receive at least 60 days' notice of
any termination or material modification of the exchange offer, except no notice
need be given if, under  extraordinary  circumstances,  either  redemptions  are
suspended under the circumstances  described below or a fund temporarily  delays
or  ceases  the sales of its  shares  because  it is  unable  to invest  amounts
effectively in accordance  with the fund's  investment  objective,  policies and
restrictions.


                                       46
<PAGE>

      If  conditions  exist  that  make  cash  payments  undesirable,  each fund
reserves  the right to honor any request  for  redemption  by making  payment in
whole or in part in securities  chosen by the fund and valued in the same way as
they would be valued for purposes of computing  the fund's net asset value.  Any
such redemption in kind will be made with readily marketable securities,  to the
extent  available.  If payment is made in  securities,  a shareholder  may incur
brokerage  expenses in  converting  these  securities  into cash.  Each fund has
elected,  however, to be governed by Rule 18f-1 under the Investment Company Act
of 1940,  under which it is obligated to redeem  shares solely in cash up to the
lesser of $250,000 or 1% of its net asset value during any 90-day period for one
shareholder. This election is irrevocable unless the SEC permits its withdrawal.

      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.

      SERVICE  ORGANIZATIONS.  A fund may authorize service  organizations,  and
their agents, to accept on its behalf purchase and redemption orders that are in
"good  form."  A fund  will  be  deemed  to have  received  these  purchase  and
redemption  orders when a service  organization  or its agent accepts them. Like
all customer  orders,  these orders will be priced based on the fund's net asset
value next computed after receipt of the order by the service  organizations  or
their  agents.   Service  organizations  may  include  retirement  plan  service
providers  who  aggregate  purchase and  redemption  instructions  received from
numerous retirement plans or plan participants.

      AUTOMATIC INVESTMENT PLAN. PaineWebber offers an automatic investment plan
with a minimum initial investment of $1,000 through which a fund will deduct $50
or more on a monthly, quarterly, semi-annual or annual basis from the investor's
bank  account to invest  directly in the fund.  Participation  in the  automatic
investment  plan  enables an  investor  to use the  technique  of  "dollar  cost
averaging." When an investor invests the same dollar amount each month under the
plan,  the investor  will purchase more shares when a fund's net asset value per
share is low and fewer shares when the net asset value per share is high.  Using
this technique,  an investor's  average  purchase price per share over any given
period will be lower than if the investor  purchased a fixed number of shares on
a monthly basis during the period.  Of course,  investing  through the automatic
investment  plan does not assure a profit or protect  against  loss in declining
markets. Additionally, because the automatic investment plan involves continuous
investing  regardless of price levels,  an investor  should  consider his or her
financial  ability to continue  purchases  through  periods of both low and high
price levels.

      SYSTEMATIC   WITHDRAWAL  PLAN.  The  systematic   withdrawal  plan  allows
investors to set up monthly,  quarterly (March,  June,  September and December),
semi-annual  (June and  December) or annual  (December)  withdrawals  from their
PaineWebber  Mutual  Fund  accounts.   Minimum  balances  and  withdrawals  vary
according to the class of shares:

o     Class A  and Class  C shares.  Minimum  value of  fund  shares  is $5,000;
      minimum withdrawals of $100.

o     Class B shares. Minimum value of  fund shares is $20,000; minimum monthly,
      quarterly, and semi-annual and  annual withdrawals of $200, $400, $600 and
      $800, respectively.

      Withdrawals under the systematic  withdrawal plan will not be subject to a
contingent  deferred sales charge if the investor  withdraws no more than 12% of
the  value of the fund  account  when the  investor  signed up for the Plan (for
Class B shares,  annually; for Class A and Class C shares, during the first year
under  the  Plan).   Shareholders  who  elect  to  receive  dividends  or  other
distributions in cash may not participate in this plan.

      An  investor's  participation  in  the  systematic  withdrawal  plan  will
terminate  automatically if the "Initial Account Balance" (a term that means the
value of the fund account at the time the investor  elects to participate in the
systematic withdrawal plan), less aggregate redemptions made other than pursuant
to the systematic  withdrawal  plan, is less than the minimum  values  specified
above.  Purchases of additional shares of a fund concurrent with withdrawals are
ordinarily  disadvantageous to shareholders  because of tax liabilities and, for
Class A  shares,  initial  sales  charges.  On or about  the 20th of a month for
monthly,  quarterly,  semi-annual and annual plans, PaineWebber will arrange for
redemption  by the funds of  sufficient  fund shares to provide  the  withdrawal
payments specified by participants in the funds' systematic withdrawal plan. The
payments  generally are mailed  approximately  five Business Days (defined under
"Valuation of Shares") after the redemption date. Withdrawal payments should not
be  considered  dividends,  but  redemption  proceeds.  If periodic  withdrawals
continually exceed reinvested dividends and other distributions, a shareholder's
investment may be  correspondingly  reduced. A shareholder may change the amount

                                       47

of the  systematic  withdrawal  or  terminate  participation  in the  systematic
withdrawal  plan at any time without  charge or penalty by written  instructions
with  signatures   guaranteed  to  PaineWebber  or  PFPC  Inc.  Instructions  to
participate in the plan, change the withdrawal amount or terminate participation
in the plan will not be  effective  until five days after  written  instructions
with signatures  guaranteed are received by PFPC.  Shareholders  may request the
forms needed to establish a systematic  withdrawal  plan from their  PaineWebber
Financial Advisors, correspondent firms or PFPC at 1-800-647-1568.

      INDIVIDUAL  RETIREMENT ACCOUNTS.  Self-directed IRAs are available through
PaineWebber in which purchases of PaineWebber mutual funds and other investments
may be made. Investors considering  establishing an IRA should review applicable
tax laws and should consult their tax advisers.

      TRANSFER  OF  ACCOUNTS.  If  investors  holding  shares  of  a  fund  in a
PaineWebber brokerage account transfer their brokerage accounts to another firm,
the fund shares  will be moved to an account  with PFPC.  However,  if the other
firm has  entered  into a  selected  dealer  agreement  with  Mitchell  Hutchins
relating  to the fund,  the  shareholder  may be able to hold fund  shares in an
account with the other firm.

PAINEWEBBER RMA RESOURCE ACCUMULATION PLAN (SERVICEMARK);
PAINEWEBBER RESOURCE MANAGEMENT ACCOUNT(REGISTERED MARK)) (RMA)(REGISTERED MARK)

      Shares of  PaineWebber  mutual funds (each a "PW Fund" and,  collectively,
the "PW Funds") are available for purchase through the RMA Resource Accumulation
Plan  ("Plan") by  customers  of  PaineWebber  and its  correspondent  firms who
maintain Resource Management Accounts ("RMA accountholders"). The Plan allows an
RMA  accountholder  to  continually  invest  in one or more of the PW  Funds  at
regular intervals, with payment for shares purchased automatically deducted from
the client's RMA account. The client may elect to invest at monthly or quarterly
intervals and may elect either to invest a fixed dollar amount (minimum $100 per
period) or to purchase a fixed number of shares. A client can elect to have Plan
purchases executed on the first or fifteenth day of the month. Settlement occurs
three Business Days (defined under  "Valuation of Shares") after the trade date,
and the  purchase  price of the  shares is  withdrawn  from the  investor's  RMA
account on the settlement  date from the following  sources and in the following
order:  uninvested cash balances,  balances in RMA money market funds, or margin
borrowing power, if applicable to the account.

      To participate in the Plan, an investor must be an RMA accountholder, must
have  made an  initial  purchase  of the  shares  of each PW Fund  selected  for
investment under the Plan (meeting  applicable minimum investment  requirements)
and must complete and submit the RMA Resource Accumulation Plan Client Agreement
and Instruction Form available from PaineWebber. The investor must have received
a current  prospectus  for each PW Fund selected prior to enrolling in the Plan.
Information about mutual fund positions and outstanding  instructions  under the
Plan are noted on the RMA accountholder's account statement.  Instructions under
the Plan may be  changed  at any  time,  but may take up to two  weeks to become
effective.

      The  terms of the Plan,  or an RMA  accountholder's  participation  in the
Plan, may be modified or terminated at any time. It is anticipated  that, in the
future, shares of other PW Funds and/or mutual funds other than the PW Funds may
be offered through the Plan.

      PERIODIC INVESTING AND DOLLAR COST AVERAGING. Periodic investing in the PW
Funds or other  mutual  funds,  whether  through  the Plan or  otherwise,  helps
investors  establish and maintain a disciplined  approach to accumulating assets
over time,  de-emphasizing the importance of timing the market's highs and lows.
Periodic  investing  also permits an investor to take  advantage of "dollar cost
averaging."  By  investing a fixed  amount in mutual fund shares at  established
intervals,  an investor  purchases more shares when the price is lower and fewer
shares  when  the  price  is  higher,  thereby  increasing  his or  her  earning
potential.  Of course,  dollar  cost  averaging  does not  guarantee a profit or
protect  against a loss in a declining  market,  and an investor should consider
his or her financial  ability to continue  investing through periods of both low
and high share  prices.  However,  over time,  dollar cost  averaging  generally
results in a lower average original investment cost than if an investor invested
a larger dollar amount in a mutual fund at one time.

      PAINEWEBBER'S RESOURCE MANAGEMENT ACCOUNT. In order to enroll in the Plan,
an  investor  must have  opened an RMA account  with  PaineWebber  or one of its
correspondent  firms.  The RMA  account  is  PaineWebber's  comprehensive  asset
management  account and offers  investors a number of  features,  including  the
following:

      o     monthly   Premier  account  statements  that   itemize  all  account
            activity,  including investment transactions,  checking activity and
            Gold  MasterCard(Registered)  transactions  during the  period,  and
            provide  unrealized  and realized  gain and loss  estimates for most
            securities held in the account;


                                       48
<PAGE>

      o     comprehensive year-end summary statements  that  provide information
            on  account  activity  for  use  in  tax  planning  and  tax  return
            preparation;

      o     automatic  "sweep" of uninvested  cash into the RMA  accountholder's
            choice of one of the six RMA money  market  funds-RMA  Money  Market
            Portfolio,  RMA U.S.  Government  Portfolio,  RMA Tax-Free Fund, RMA
            California Municipal Money Fund, RMA New Jersey Municipal Money Fund
            and RMA New York  Municipal  Money Fund.  An  investment  in a money
            market fund is not  insured or  guaranteed  by the  Federal  Deposit
            Insurance  Corporation or any other  government  agency.  Although a
            money market fund seeks to preserve the value of your  investment at
            $1.00 per share,  it is  possible  to lose money by  investing  in a
            money market fund.

      o     check writing, with no per-check usage charge,  no minimum amount on
            checks  and no maximum  number of checks  that can be  written.  RMA
            accountholders can code their checks to classify  expenditures.  All
            canceled checks are returned each month;

      o     Gold  MasterCard, with or  without a line of  credit, which provides
            RMA  accountholders  with direct access to their accounts and can be
            used with automatic teller machines worldwide. Purchases on the Gold
            MasterCard  are debited to the RMA account once monthly,  permitting
            accountholders to remain invested for a longer period of time;

      o     24-hour access to account information through toll-free numbers, and
            more detailed personal assistance during business hours from the RMA
            Service Center;

      o     expanded account  protection to  $100  million in  the  event of the
            liquidation of PaineWebber. This protection does not apply to shares
            of the RMA money market funds or the PW Funds  because  those shares
            are held at PFPC and not through PaineWebber; and

      o     automatic  direct  deposit  of  checks  into  your RMA  account  and
            automatic withdrawals from the account.

      The annual  account fee for an RMA account is $85, which includes the Gold
MasterCard,  with an additional  fee of $40 if the investor  selects an optional
line of credit with the Gold MasterCard.

                          CONVERSION OF CLASS B SHARES

      Class B shares of a fund will  automatically  convert to Class A shares of
that fund,  based on the relative net asset values per share of the two classes,
as of the  close  of  business  on the  first  Business  Day (as  defined  under
"Valuation  of  Shares")  of the  month in which the  sixth  anniversary  of the
initial  issuance of such Class B shares occurs.  For the purpose of calculating
the  holding  period  required  for  conversion  of Class B shares,  the date of
initial  issuance  shall  mean (i) the date on which  such  Class B shares  were
issued or (ii) for Class B shares obtained  through an exchange,  or a series of
exchanges,  the date on which  the  original  Class B shares  were  issued.  For
purposes of conversion to Class A shares,  Class B shares purchased  through the
reinvestment  of dividends  and other  distributions  paid in respect of Class B
shares will be held in a separate  sub-account.  Each time any Class B shares in
the shareholder's  regular account (other than those in the sub-account) convert
to Class A shares,  a pro rata portion of the Class B shares in the  sub-account
will also convert to Class A shares. The portion will be determined by the ratio
that the shareholder's  Class B shares converting to Class A shares bears to the
shareholder's  total Class B shares not  acquired  through  dividends  and other
distributions.

      The  conversion  feature is subject to the continuing  availability  of an
opinion of counsel to the effect that the dividends and other distributions paid
on Class A and Class B shares will not result in "preferential  dividends" under
the Internal  Revenue Code and that the conversion of shares does not constitute
a taxable event. If the conversion  feature ceased to be available,  the Class B
shares  would not be  converted  and would  continue to be subject to the higher
ongoing  expenses  of the  Class B  shares  beyond  six  years  from the date of
purchase.  Mitchell  Hutchins has no reason to believe that this  condition will
not continue to be met.

                               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  Business  Day,  which is
defined as 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.  Currently  the New York  Stock
Exchange is closed on the observance of the following holidays:  New Year's Day,


                                       49
<PAGE>

Martin  Luther  King,  Jr. Day,  Presidents'  Day,  Good Friday,  Memorial  Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas 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 such 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 (for Low  Duration
Fund)  the  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.  Where market  quotations are readily  available,
portfolio  securities  are valued based upon market  quotations,  provided those
quotations  adequately  reflect,  in the  judgment of  Mitchell  Hutchins or the
sub-adviser,  the fair value of the security.  Where those market quotations are
not readily available, securities 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.  All other  securities and other
assets  are  valued at fair  value as  determined  in good faith by or under the
direction of the applicable  board.  It should be recognized that judgment often
plays a greater role in valuing thinly traded  securities,  including many 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. The amortized
cost method of  valuation  generally is used to value debt  obligations  with 60
days or less remaining until maturity,  unless the applicable  board  determines
that this does not represent fair value.

      All  investments  quoted in foreign  currency will be valued daily in U.S.
dollars on the basis of the current  foreign  currency  exchange  rate.  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 applicable 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.

                             PERFORMANCE INFORMATION

      The funds'  performance  data quoted in advertising and other  promotional
materials ("Performance  Advertisements") represent past performance and are not
intended to indicate  future  performance.  The investment  return and principal
value  of an  investment  will  fluctuate  so that an  investor's  shares,  when
redeemed, may be worth more or less than their original cost.

      TOTAL  RETURN   CALCULATIONS.   Average   annual   total   return   quotes
("Standardized  Return")  used in each  fund's  Performance  Advertisements  are
calculated according to the following formula:
               n
       P(1 + T)  =  ERV
     where:    P =  a hypothetical initial payment of $1,000 to  purchase shares
                    of a specified class
               T =  average annual total return of shares of that class 
               n =  number of years
             ERV =  ending redeemable value of a hypothetical $1,000  payment at
                    the beginning of that period.

      Under  the  foregoing  formula,  the  time  periods  used  in  Performance
Advertisements  will be based on rolling calendar quarters,  updated to the last
day of the most recent  quarter  prior to submission  of the  advertisement  for
publication.  Total return,  or "T" in the formula above, is computed by finding
the average annual change in the value of an initial $1,000  investment over the
period.  In calculating the ending  redeemable  value,  for Class A shares,  the
maximum  4.0% sales charge  (3.0% for Low  Duration  Fund) is deducted  from the
initial  $1,000  payment  and,  for Class B and Class C shares,  the  applicable
contingent  deferred  sales charge imposed on a redemption of Class B or Class C
shares held for the period is deducted.  All dividends  and other  distributions
are assumed to have been reinvested at net asset value.

      The funds also may refer in  Performance  Advertisements  to total  return
performance  data that are not  calculated  according  to the  formula set forth
above ("Non-Standardized  Return"). The funds calculate  Non-Standardized Return
for specified periods of time by assuming an investment of $1,000 in fund shares
and assuming the reinvestment of all dividends and other distributions. The rate
of return is determined by subtracting  the initial value of the investment from

                                       50
<PAGE>

the ending value and by dividing the  remainder  by the initial  value.  Neither
initial  nor  contingent  deferred  sales  charges  are taken  into  account  in
calculating Non-Standardized Return; the inclusion of those charges would reduce
the return.

      Both Standardized  Return and  Non-Standardized  Return for Class B shares
for periods of over six years reflect  conversion of the Class B shares to Class
A shares at the end of the sixth year.

      The following  tables show  performance  information for each class of the
funds' shares outstanding for the periods indicated.  All returns for periods of
more than one year are expressed as an average annual return.

*  All Standardized Return figures for  Class A shares  reflect deduction of the
   current  maximum  sales  charge of 4.0%  (3.0% for Low  Duration  Fund).  All
   Standardized  Return figures for Class B and Class C shares reflect deduction
   of the applicable  contingent  deferred sales charges imposed on a redemption
   of shares  held for the  period.  Class Y shares do not  impose an initial or
   contingent deferred sales charge;  therefore,  the performance information is
   the same for both  standardized  return and  non-standardized  return for the
   periods indicated.

      YIELD.   Yields  used  in  each  fund's  Performance   Advertisements  are
calculated by dividing the fund's  interest  income  attributable  to a class of
shares for a 30-day  period  ("Period"),  net of expenses  attributable  to such
class,  by the  average  number of  shares of such  class  entitled  to  receive
dividends  during  the  Period  and  expressing  the  result  as  an  annualized
percentage (assuming semi-annual  compounding) of the maximum offering price per
share (in the case of Class A shares)  or the net asset  value per share (in the
case of Class B and Class C shares) at the end of the Period.  Yield  quotations
are calculated according to the following formula:


          YIELD   =    [OBJECT OMITTED]



      where:   a=  interest earned during the Period attributable to a class of
                   shares
               b=  expenses accrued for the Period attributable  to a class of
                   shares (net of reimbursements)


                                       52
<PAGE>

               c=  the average daily number of shares of a class outstanding
                   during the Period that were entitled to receive dividends
               d=  the maximum offering price  per share (in the case of Class A
                   shares) or the net asset value per share (in the case of
                   Class B and Class C shares) on the last day of the Period.

      Except as noted below,  in determining  interest  income earned during the
Period (variable "a" in the above formula), each fund calculates interest earned
on each debt  obligation  held by it during  the  Period  by (1)  computing  the
obligation's  yield to  maturity,  based on the market  value of the  obligation
(including  actual accrued  interest) on the last business day of the Period or,
if the  obligation  was  purchased  during the Period,  the purchase  price plus
accrued  interest and (2) dividing the yield to maturity by 360, and multiplying
the resulting  quotient by the market value of the obligation  (including actual
accrued  interest) to determine the interest  income on the  obligation for each
day of the period that the obligation is in the portfolio.  Once interest earned
is  calculated  in this  fashion  for each  debt  obligation  held by the  fund,
interest  earned  during the Period is then  determined by totaling the interest
earned on all debt obligations. For purposes of these calculations, the maturity
of an obligation with one or more call provisions is assumed to be the next date
on which the obligation reasonably can be expected to be called or, if none, the
maturity  date.  With  respect to Class A shares,  in  calculating  the  maximum
offering  price per share at the end of the  Period  (variable  "d" in the above
formula) the fund's  current  maximum 4.0% (3.0% for Low Duration  Fund) initial
sales charge on Class A shares is included.

      The following  table shows the yield for each class of shares of each fund
for the 30-day period ended November 30, 1998:

      OTHER INFORMATION.  In Performance  Advertisements,  the funds may compare
their  Standardized  Return  and/or  their  Non-Standardized  Return  with  data
published by Lipper Inc. ("Lipper") for U.S.  government funds (U.S.  Government
Income Fund and Low Duration Fund), corporate bond (BBB) funds (Investment Grade

market or the market for mortgage-backed  securities, such as those published by
the Federal Reserve Bank, the Office of Thrift  Supervision,  Ginnie Mae, Fannie

also may refer in these materials to mutual fund performance  rankings and other
data, such as comparative  asset,  expense and fee levels,  published by Lipper,
CDA, Wiesenberger, ICD or Morningstar. Performance Advertisements also may refer
to  discussions  of the  funds and  comparative  mutual  fund  data and  ratings
reported in independent  periodicals,  including THE WALL STREET JOURNAL,  MONEY
Magazine,  FORBES,  BUSINESS WEEK, FINANCIAL WORLD,  BARRON'S,  FORTUNE, THE NEW
YORK TIMES, THE CHICAGO TRIBUNE,  THE WASHINGTON POST and THE KIPLINGER LETTERS.
Comparisons in Performance Advertisements may be in graphic form.

      The funds may  include  discussions  or  illustrations  of the  effects of
compounding  in  Performance  Advertisements.  "Compounding"  refers to the fact
that, if dividends or other distributions on a fund investment are reinvested in
additional  fund shares,  any future  income or capital  appreciation  of a fund
would increase the value, not only of the original fund investment,  but also of
the additional fund shares received through reinvestment. As a result, the value
of a fund  investment  would  increase  more  quickly than if dividends or other
distributions had been paid in cash.

      The funds may also compare their  performance with the performance of bank
certificates  of deposit  (CDs) as  measured by the CDA  Certificate  of Deposit
Index, the Bank Rate Monitor National Index and the averages of yields of CDs of
major banks  published by  Banxquote(R)  Money Markets.  In comparing the funds'


                                       53
<PAGE>

performance to CD performance,  investors  should keep in mind that bank CDs are
insured in whole or in part by an agency of the U.S.  government and offer fixed
principal and fixed or variable  rates of interest,  and that bank CD yields may
vary  depending on the  financial  institution  offering  the CD and  prevailing
interest  rates.  Shares of the funds are not insured or  guaranteed by the U.S.
government and returns and net asset values will fluctuate.  The debt securities
held by the funds generally have longer maturities than most CDs and may reflect
interest rate fluctuations for longer term debt securities. An investment in any
fund involves  greater risks than an investment in either a money market fund or
a CD.

                                      TAXES

      BACKUP  WITHHOLDING.  Each  fund  is  required  to  withhold  31%  of  all
dividends,  capital  gain  distributions  and  redemption  proceeds  payable  to
individuals and certain other non-corporate  shareholders who do not provide the
fund or PaineWebber with a correct taxpayer  identification number.  Withholding
at that rate also is required  from  dividends  and capital  gain  distributions
payable to those shareholders who otherwise are subject to backup withholding.

      SALE OR EXCHANGE OF FUND SHARES.  A  shareholder's  sale  (redemption)  of
shares  may  result  in a  taxable  gain  or  loss,  depending  on  whether  the
shareholder  receives more or less than his or her adjusted basis for the shares
(which  normally  includes any initial sales charge paid on Class A shares).  An
exchange  of any fund's  shares for shares of another  PaineWebber  mutual  fund
generally will have similar tax  consequences.  In addition,  if a fund's shares
are  bought  within 30 days  before or after  selling  other  shares of the fund
(regardless  of  class)  at a loss,  all or a  portion  of that loss will not be
deductible and will increase the basis of the newly purchased shares.

      SPECIAL RULE FOR CLASS A  SHAREHOLDERS.  A special tax rule applies when a
shareholder  sells or  exchanges  Class A shares  within 90 days of purchase and
subsequently  acquires Class A shares of the same or another  PaineWebber mutual
fund without paying a sales charge due to the 365-day reinstatement privilege or
the exchange privilege.  In these cases, any gain on the sale or exchange of the
original Class A shares would be increased,  or any loss would be decreased,  by
the amount of the sales  charge  paid when those  shares were  bought,  and that
amount  would  increase  the  basis  of  the  PaineWebber   mutual  fund  shares
subsequently acquired.

      CONVERSION OF CLASS B SHARES. A shareholder will recognize no gain or loss
as a result of a conversion from Class B shares to Class A shares.

      QUALIFICATION AS A REGULATED  INVESTMENT COMPANY. To qualify for treatment
as a RIC  under  the  Internal  Revenue  Code,  a 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. If any
fund failed to qualify for treatment as a RIC for any taxable year, (a) it would
be taxed as an ordinary corporation on the full amount of its taxable income for
that  year  without  being  able to  deduct  the  distributions  it makes to its
shareholders  and (b) the  shareholders  would  treat all  those  distributions,
including  distributions  of net capital gain (i.e., the excess of net long-term
capital gain over net short-term  capital loss), as dividends (that is, ordinary
income) to the extent of the fund's earnings and profits. 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.

      OTHER INFORMATION. Dividends and other distributions declared by a fund in
October,  November or December of any year and payable to shareholders of record
on a date in any of those  months  will be  deemed to have been paid by the fund
and  received  by  the   shareholders  on  December  31  of  that  year  if  the
distributions  are paid by the fund during the following  January.  Accordingly,
those  distributions  will be taxed to  shareholders  for the year in which that
December 31 falls.


                                       54

      U.S. Government Income Fund and Low Duration Fund each invests exclusively
in debt securities and receives no dividend income;  accordingly,  no portion of
the  dividends  or other  distributions  paid by these funds is eligible for the
dividends-received deduction allowed to corporations.  Although Investment Grade
Income Fund,  High Income Fund and Strategic  Income Fund are authorized to hold
equity  securities,  it is expected that any dividend  income  received by these
funds will be minimal.

      If shares of a fund are sold at a loss after  being held for six months or
less, the loss will be treated as long-term, instead of short-term, capital loss
to the  extent of any  capital  gain  distributions  received  on those  shares.
Investors  also should be aware that if shares are purchased  shortly before the
record date for any dividend or capital gain distribution,  the shareholder will
pay full price for the shares and  receive  some  portion of the price back as a
taxable distribution.

      Each fund will be subject to a nondeductible  4% excise tax ("Excise Tax")
to the  extent  it  fails  to  distribute  by  the  end  of  any  calendar  year
substantially  all of its  ordinary  income for that year and  capital  gain net
income for the one-year  period ending on November 30 of that year, plus certain
other amounts.

      Dividends and interest received,  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 (collectively "foreign taxes") that would
reduce the return on its securities.  Tax conventions  between certain countries
and the United States,  however, may reduce or eliminate foreign taxes, and many
foreign countries do not impose taxes on capital gains in respect of investments
by foreign  investors.  If more than 50% of the value of Strategic Income Fund's
total assets at the close of its taxable year  consists of securities of foreign
corporations,  it will be  eligible  to,  and  may,  file an  election  with the
Internal  Revenue  Service  that will  enable its  shareholders,  in effect,  to
receive the benefit of the foreign tax credit with respect to any foreign  taxes
it paid. Pursuant to the election, the fund would treat those taxes as dividends
paid to its  shareholders  and each shareholder (1) would be required to include
in gross income, and treat as paid by him or her, his or her proportionate share
of those  taxes,  (2) would be required to treat his or her share of those taxes
and of any dividend paid by the fund that represents income from foreign or U.S.
possessions  sources as his or her own income from those sources,  and (3) could
either  deduct the foreign  taxes deemed paid by him or her in computing  his or
her  taxable  income  or,  alternatively,   use  the  foregoing  information  in
calculating  the  foreign tax credit  against his or her federal  income tax. If
Strategic  Income Fund makes this election,  it will report to its  shareholders
shortly  after each taxable year their  respective  shares of foreign taxes paid
and the income from sources  within,  and taxes paid to,  foreign  countries and
U.S.  possessions.  Individuals  who have no more  than $300  ($600 for  married
persons filing  jointly) of creditable  foreign taxes included on Forms 1099 and
all of whose foreign source income is "qualified  passive income" may elect each
year to be exempt from the extremely  complicated foreign tax credit limitation,
in which event they would be able to claim a foreign tax credit  without  having
to file the detailed Form 1116 that otherwise is required.

      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 qualify
as permissible income under the Income Requirement.

      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  same  or
substantially  similar  property,  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  similar
property.  In addition,  if the appreciated financial position is itself a short
sale or such a contract, acquisition of the underlying property or substantially
similar  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  similar
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).


                                       55
<PAGE>

      A fund  may  acquire  (1) zero  coupon  or other  securities  issued  with
original issue discount ("OID") or (2) Treasury  inflation-protected  securities
("TIPS"),  on which principal is adjusted based on changes in the Consumer Price
Index.  A fund must  include  in its gross  income  the  portion of 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,  Investment Grade Income Fund, High Income Fund
and  Strategic  Income Fund each must include in its gross income  securities it
receives as  "interest"  on  payment-in-kind  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  and avoid  imposition  of the Excise Tax, it might 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.  The 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.

                                OTHER INFORMATION

      MASSACHUSETTS  BUSINESS  TRUSTS.  Each  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 its  Trust.  However,  each  Trust's
Declaration of Trust disclaims  shareholder liability for acts or obligations of
the Trust or the 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. Each
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.

      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 sales charges,
if any,  distribution  and/or  service 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 sales charges and other
expenses  applicable to the different classes of shares of the funds will affect
the  performance  of  those  classes.  Each  share  of a  fund  is  entitled  to
participate  equally in dividends,  other  distributions and the proceeds of any
liquidation of that fund. However, due to the differing expenses of the classes,
dividends and liquidation proceeds on Class A, B, C and Y shares will differ.

      VOTING RIGHTS. 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 a Trust may elect all of the board  members of that 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 a Rule 12b-1 Plan as it relates to the class. The shares of each
series of Managed Trust and Securities  Trust will be voted  separately,  except
when an aggregate vote of all the series is required by law.

      The funds do not hold annual  meetings.  Shareholders of record of no less
than two-thirds of the  outstanding  shares of a 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 a Trust.

      CLASS-SPECIFIC  EXPENSES.  Each fund may determine to allocate  certain of
its  expenses  (in  addition to service and  distribution  fees) to the specific
classes of its shares to which those  expenses  are  attributable.  For example,
Class B and Class C shares bear  higher  transfer  agency  fees per  shareholder
account than those borne by Class A or Class Y shares. The higher fee is imposed
due to the higher  costs  incurred  by the  transfer  agent in  tracking  shares
subject to a contingent  deferred sales charge  because,  upon  redemption,  the
duration  of the  shareholder's  investment  must  be  determined  in  order  to
determine the applicable charge. Although the transfer agency fee will differ on
a per account basis as stated above,  the specific  extent to which the transfer
agency fees will differ between the classes as a percentage of net assets is not
certain,  because the fee as a percentage  of net assets will be affected by the
number of  shareholder  accounts in each class and the  relative  amounts of net
assets in each class.

      PRIOR  NAMES.  Prior to October 20, 1995,  Low Duration  Fund was known as
"PaineWebber  Short-Term  U.S.  Government  Income  Fund." Prior to November 10,
1995, the Class C shares of all the funds were called "Class D" shares,  and the
Class Y shares of U.S.  Government Income Fund and Low Duration Fund were called

                               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, D. 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
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.

                                    A-1

      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
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.
