                     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.

        Each fund is a money  market  fund that  invests in high  quality  money
market instruments that have, or are deemed to have,  remaining maturities of 13
months or less.  Money market  instruments are short-term  debt-obligations  and
similar  securities.  They also  include  longer  term bonds that have  variable
interest  rates  or  other  special   features  that  give  them  the  financial
characteristics   of  short-term   debt.  Each  fund  may  purchase  only  those
obligations that Mitchell Hutchins determines, pursuant to procedures adopted by
the board,  present  minimal  credit  risks and are "First Tier  Securities"  as
defined  in Rule 2a-7  under the  Investment  Company  Act of 1940,  as  amended
("Investment Company Act").

        MONEY MARKET FUND'S investment  objective is to earn high current income
to the extent consistent with the preservation of capital and the maintenance of
liquidity  through  investments  in a  diversified  portfolio  of high  quality,
short-term,  U.S.  dollar-denominated  money  market  instruments.   The  fund's
investments include (1) U.S. and foreign government securities,  (2) obligations
of U.S. and foreign banks, (3) commercial paper and other short-term obligations
of U.S. and foreign corporations, partnerships, trusts and similar entities, (4)
repurchase agreements and (5) investment company securities.

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

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

        The 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 up to 33 1/3% of the value of its total  assets,  including  reverse
repurchase  agreements,  for  temporary  purposes  The  fund may  invest  in the
securities of other money market funds.

        GOVERNMENT  SECURITIES  FUND'S  investment  objective  is to  earn  high
current income to the extent consistent with the preservation of capital and the
maintenance of liquidity through investments in a diversified  portfolio of high
quality,  short-term, U.S. dollar-denominated money market instruments. The fund
invests in U.S.  government  securities  with interest  income that is generally
exempt from state and local income taxation and intends to emphasize investments
in  securities  eligible  for this  exemption  in the maximum  number of states.
Securities  generally  eligible for this  exemption  include those issued by the
U.S.   Treasury  and  those   issued  by  certain   agencies,   authorities   or
instrumentalities of the U.S. government, including the Federal Home Loan Banks,
Federal Farm Credit Banks Funding Corp. and SLM Holding Corp. (formerly known as
the Student Loan Marketing Association). The fund will not enter into repurchase
agreements.

        Under extraordinary circumstances, however, such as when securities with
interest  income that is generally  exempt from state and local income  taxation
are unavailable at prices deemed reasonable by Mitchell  Hutchins,  the fund may
temporarily  hold cash or invest in other U.S.  government  securities,  such as
securities issued by Ginnie Mae, also known as the Government  National Mortgage
Association,  and  Freddie  Mac,  also known as the Federal  Home Loan  Mortgage
Corporation, and the Small Business Administration.

                                       2

        Each investor  should  consult its own tax adviser to determine  whether
distributions  from the fund derived from interest on its portfolio  investments
are exempt from state income taxation in the investor's own state.

        The 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  up to 33  1/3% of the  value  of its  total  assets  for  temporary
purposes. The fund may invest in the securities of other money market funds that
have similar tax characteristics.

        TREASURY SECURITIES FUND'S investment  objective is to earn high current
income  to the  extent  consistent  with the  preservation  of  capital  and the
maintenance of liquidity through investments in a diversified  portfolio of high
quality,  short-term, U.S. dollar-denominated money market instruments. The fund
invests  substantially all its assets in securities issued by the U.S. Treasury,
which are  supported  by the full  faith and credit of the  United  States.  The
interest  income on these  securities  is generally  exempt from state and local
income tax. The fund will not enter into repurchase agreements.

        Each investor  should  consult its own tax adviser to determine  whether
distributions  from the fund derived from interest on its portfolio  investments
are exempt from state income taxation in the investor's own state.

        The 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  up to 33  1/3% of the  value  of its  total  assets  for  temporary
purposes. The fund may invest in the securities of other money market funds that
have similar tax characteristics.

              THE FUNDS' INVESTMENTS, RELATED RISKS AND LIMITATIONS

        The following  supplements the  information  contained in the Prospectus
and above  concerning each fund's  investments,  related risks and  limitations.
Except as  otherwise  indicated  in the  Prospectus  or the SAI,  the funds have
established  no policy  limitations  on their ability to use the  investments or
techniques  discussed in these documents.  New forms of money market instruments
continue  to be  developed.  The funds may  invest in these  instruments  to the
extent consistent with their investment objectives.

        YIELDS  AND  CREDIT  RATINGS  OF MONEY  MARKET  INSTRUMENTS;  FIRST TIER
SECURITIES. The yields on the money market instruments in which the funds invest
are  dependent  on  a  variety  of  factors,   including  general  money  market
conditions,  conditions  in  the  particular  market  for  the  obligation,  the
financial condition of the issuer, the size of the offering, the maturity of the
obligation  and the  ratings of the issue.  The ratings  assigned by  nationally
recognized  statistical rating organizations ("rating agencies") represent their
opinions as to the quality of the obligations  they undertake to rate.  Ratings,
however,  are general and are not absolute  standards of quality.  Consequently,
obligations with the same rating,  maturity and interest rate may have different
market prices.

        Subsequent  to its purchase by a fund, an issue may cease to be rated or
its rating may be reduced.  If a security in a fund's  portfolio  ceases to be a
First Tier  Security  or Mitchell  Hutchins  becomes  aware that a security  has
received a rating below the second highest rating by any rating agency, Mitchell
Hutchins and, in certain  cases,  a fund's board,  will consider  whether a fund
should  continue  to hold the  obligation.  A First Tier  Security is either (1)
rated in the highest short-term rating category by at least two rating agencies,
(2) rated in the highest short-term rating category by a single rating agency if
only that rating  agency has assigned the  obligation a short-term  rating,  (3)
issued by an issuer that has received such a short-term rating with respect to a
security that is comparable in priority and security, (4) subject to a guarantee
rated in the highest  short-term  rating  category or issued by a guarantor that
has received the highest  short-term  rating for a comparable debt obligation or
(5) unrated,  but determined by Mitchell Hutchins to be of comparable quality. A
First Tier Security rated in the highest short-term  category by a single rating
agency at the time of purchase  that  subsequently  receives a rating  below the
highest  rating  category  from a  different  rating  agency may  continue to be
considered a First Tier Security.


                                       3

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

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

        COMMERCIAL PAPER AND OTHER SHORT-TERM OBLIGATIONS. Money Market Fund may
purchase  commercial  paper,  which includes  short-term  obligations  issued by
corporations,  partnerships,  trusts or other  entities  to  finance  short-term
credit  needs.  The fund  also may  purchase  non-convertible  debt  obligations
subject  to  maturity  constraints  imposed  by Rule 2a-7  under the  Investment
Company Act.

        ASSET-BACKED  SECURITIES.  Money Market Fund and  Government  Securities
Fund may invest in securities  that are comprised of financial  assets that have
been  securitized  through the use of trusts or special purpose  corporations or
other  entities.  Such  assets may  include  motor  vehicle  and other  types of
installment sales contracts,  home equity loans, leases of various types of real
and personal  property and  receivables  from  revolving  credit  (credit  card)
agreements  or other types of financial  assets.  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.  See "The Funds'  Investments,  Related Risks and Limitations --
Credit and Liquidity Enhancements."

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

        Generally,  each fund may  exercise  demand  features (1) upon a default
under the terms of the  underlying  security,  (2) to maintain its  portfolio in
accordance  with its  investment  objective and policies or applicable  legal or
regulatory  requirements  or (3) as needed to provide  liquidity  to the fund in
order to meet  redemption  requests.  The  ability of a bank or other  financial
institution to fulfill its  obligations  under a letter of credit,  guarantee or
other liquidity arrangement might be affected by possible financial difficulties
of its  borrowers,  adverse  interest  rate or economic  conditions,  regulatory
limitations  or other  factors.  The interest  rate on floating rate or variable
rate  securities  ordinarily is readjusted on the basis of the prime rate of the
bank that  originated the financing or some other index or published  rate, such
as the 90-day U.S.  Treasury bill rate, or is otherwise  reset to reflect market
rates of interest.  Generally,  these interest rate adjustments cause the market
value of floating rate and variable rate  securities to fluctuate  less than the
market value of fixed rate securities.

        VARIABLE  AMOUNT MASTER  DEMAND  NOTES.  Money Market Fund may invest in
variable amount master demand notes, which are unsecured redeemable  obligations
that permit investment of varying amounts at fluctuating  interest rates under a
direct agreement  between the fund and an issuer.  The principal amount of these



                                       4
<PAGE>

notes may be  increased  from time to time by the parties  (subject to specified
maximums)  or  decreased  by the fund or the issuer.  These notes are payable on
demand and may or may not be rated.

        INVESTING IN FOREIGN SECURITIES. Money Market Fund's investments in U.S.
dollar-denominated  securities  of foreign  issuers may  involve  risks that are
different  from  investments  in U.S.  issuers.  These risks may include  future
unfavorable  political and economic  developments,  possible  withholding taxes,
seizure of foreign deposits,  currency controls,  interest  limitations or other
governmental restrictions that might affect the payment of principal or interest
on the fund's  investments.  Additionally,  there may be less publicly available
information  about foreign  issuers  because they may not be subject to the same
regulatory requirements as domestic issuers.

        CREDIT  AND  LIQUIDITY  ENHANCEMENTS.  Money  Market  Fund may invest in
securities  that have credit or liquidity  enhancements or the fund may purchase
these types of enhancements in the secondary  market.  Such  enhancements may be
structured  as demand  features  that permit the fund to sell the  instrument at
designated  times and prices.  These credit and  liquidity  enhancements  may be
backed by  letters  of credit or other  instruments  provided  by banks or other
financial  institutions  whose credit standing affects the credit quality of the
underlying  obligation.  Changes  in  the  credit  quality  of  these  financial
institutions  could  cause  losses to the fund and affect its share  price.  The
credit and liquidity  enhancements may have conditions that limit the ability of
the fund to use them when the fund wished to do so.

        ILLIQUID  SECURITIES.  The term "illiquid  securities"  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,  repurchase agreements maturing in more than seven
days and restricted securities other than those Mitchell Hutchins has determined
are liquid pursuant to guidelines established by the funds' board. To the extent
the  funds  invest  in  illiquid  securities,  they may not be able  readily  to
liquidate such  investments and may have to sell other  investments if necessary
to raise cash to meet their obligations.

        Restricted  securities  are not  registered  under the Securities Act of
1933, as amended ("Securities Act") and may be sold only in privately negotiated
or other  exempted  transactions  or after a  registration  statement  under the
Securities Act 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.   A  large
institutional market has developed for many U.S. and foreign securities that are
not registered under the Securities Act. Institutional  investors generally will
not seek to sell these instruments to the general public, but instead will often
depend either on an efficient  institutional  market in which such  unregistered
securities can be readily resold or on an issuer's ability to honor a demand for
repayment.  Therefore, the fact that there are contractual or legal restrictions
on resale to the general public or certain  institutions  is not  dispositive of
the liquidity of such investments.

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

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


                                       5
<PAGE>

transfer)  and (4)  the  existence  of  demand  features  or  similar  liquidity
enhancements.  Mitchell Hutchins monitors the liquidity of restricted securities
in each fund's  portfolio  and reports  periodically  on such  decisions  to the
board.

        REPURCHASE  AGREEMENTS.  Repurchase agreements are transactions in which
Money  Market 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. Securities or other obligations subject to repurchase
agreements  may have  maturities  in excess  of 13  months.  The fund  maintains
custody of the underlying obligations prior to their repurchase,  either through
its  regular   custodian   or  through  a  special   "tri-party"   custodian  or
sub-custodian  that  maintains  separate  accounts  for  both  the  fund and its
counterparty.  Thus,  the obligation of the  counterparty  to pay the repurchase
price on the date  agreed to or upon  demand  is,  in  effect,  secured  by such
obligations.

        Repurchase  agreements  carry certain risks not  associated  with direct
investments in securities,  including a possible  decline in the market value of
the  underlying  obligations.  If their value  becomes less than the  repurchase
price,  plus any agreed-upon  additional  amount,  the counterparty must provide
additional  collateral so that at all times the  collateral is at least equal to
the repurchase  price plus any  agreed-upon  additional  amount.  The difference
between the total amount to be received upon  repurchase of the  obligations and
the price that was paid by the 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.  The fund intends to
enter  into  repurchase  agreements  only with  counterparties  in  transactions
believed by Mitchell Hutchins to present minimum credit risks.

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

        Reverse  repurchase  agreements  involve  the risk that the buyer of the
securities  sold by the fund might be unable to deliver them when the 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  the  fund's
obligation to repurchase the  securities,  and the fund's use of the proceeds of
the reverse  repurchase  agreement may  effectively  be restricted  pending such
decision.

        WHEN-ISSUED  AND DELAYED  DELIVERY  SECURITIES.  The funds 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 funds later than
the normal  settlement  date for such  securities at a stated price and yield. 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  a loss or missing  an  opportunity  to make an
alternative investment.

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


                                       6
<PAGE>

        INVESTMENTS  IN OTHER  INVESTMENT  COMPANIES.  Each  fund may  invest in
securities  of other  money  market  funds,  subject to  Investment  Company Act
limitations,  which at present restrict these investments in the aggregate to no
more than 10% of the fund's total assets. The shares of other money market funds
are subject to the  management  fees and other  expenses of those funds.  At the
same time,  a fund would  continue to pay its own  management  fees and expenses
with  respect to all its  investments,  including  shares of other money  market
funds.  A fund may invest in the  securities  of other money  market  funds when
Mitchell  Hutchins believes that (1) the amounts to be invested are too small or
are  available  too late in the day to be  effectively  invested  in other money
market  instruments,  (2) shares of other money  market  funds  otherwise  would
provide a better return than direct investment in other money market instruments
or (3) such investments would enhance the fund's liquidity.

        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 portfolios  securities must maintain acceptable  collateral
with the fund's  custodian in an amount,  marked to market daily, at least equal
to the  market  value  of the  securities  loaned,  plus  accrued  interest  and
dividends.  Acceptable collateral is limited to cash, U.S. government securities
and irrevocable  letters of credit that meet certain  guidelines  established by
Mitchell  Hutchins.  A fund may  reinvest  any cash  collateral  in money market
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. A fund may pay reasonable  fees in connection  with a loan and may pay the
borrower or placing  broker a negotiated  portion of the interest  earned on the
reinvestment of cash held as collateral.  A fund will receive amounts equivalent
to any interest, dividends 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 its interest.

        Pursuant  to  procedures  adopted  by the board  governing  each  fund's
securities  lending  program,  PaineWebber has been retained to serve as lending
agent  for the  funds.  The  board  also  has  authorized  the  payment  of fees
(including  fees  calculated  as a percentage of invested  cash  collateral)  to
PaineWebber for these  services.  The 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 funds'  securities
lending program.

        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 its obligation or commitment under such transactions.

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.

        Each fund will not:

        (1)   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.


                                       7
<PAGE>


        The  following  interpretation  applies  to, but is not a part of,  this
fundamental  restriction:   Mortgageand  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.

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

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

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

        (4)   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.

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

        (5)   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.

        (6)   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.

        (7)   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.

        NON-FUNDAMENTAL  LIMITATIONS.  The following investment restrictions are
non-fundamental  and may be changed by the vote of the board without shareholder
approval.

        Each fund will not:

        (1)   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.

                                       8

        (2)   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.

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

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

** Mrs.  Alexander,  Mr.  Bewkes,  Ms.  Farrell and Mr.  Storms are  "interested
persons" of the fund as defined in the Investment Company Act by virtue of their
positions with Mitchell Hutchins, PaineWebber, and/or PW Group.

        The Trust pays  trustees who are not  "interested  persons" of the Trust
$1,000 annually for each series and up to $150 per series for each board meeting
and each separate  meeting of a board  committee.  The Trust presently has three
series and thus pays each such  trustee  $3,000  annually,  plus any  additional
amounts  due for board or  committee  meetings.  Each  chairman of the audit and
contract  review  committees of  individual  funds within the  PaineWebber  fund
complex receives additional compensation, aggregating $15,000 annually, from the
relevant  funds.  All  trustees  are  reimbursed  for any  expenses  incurred in
attending meetings. Trustees and officers of the Trust own in the aggregate less
than 1% of the outstanding shares of any class of each fund. Because PaineWebber
and Mitchell Hutchins perform  substantially all the services  necessary for the
operation of the Trust, the Trust requires no employees. No officer, director or
employee of Mitchell Hutchins or PaineWebber presently receives any compensation
from the Trust for acting as a trustee or officer.

        Under a  contract  with  PaineWebber  dated  April 15,  1996  ("Mitchell
Hutchins  Contract"),  Mitchell  Hutchins serves as the Trust's  sub-adviser and
sub-administrator.  Under the Mitchell Hutchins  Contract,  PaineWebber (not the
Trust) pays Mitchell  Hutchins a fee,  computed  daily and paid  monthly,  at an
annual  rate of 50% of the  fees  paid by each  fund to  PaineWebber  under  the
PaineWebber Contract, net of waivers and/or reimbursements.

        During each of the periods  indicated,  PaineWebber paid (or accrued) to
Mitchell  Hutchins the fees indicated  below under either the Mitchell  Hutchins
Contract or a predecessor agreement:

</TABLE>

        Under the terms of the Advisory  Contract,  each fund bears all expenses
incurred in its  operation  that are not  specifically  assumed by  PaineWebber.
General  expenses  of the Trust  not  readily  identifiable  as  belonging  to a
specific fund or to the Trust's  other series are  allocated  among series by or
under the  direction  of the board of trustees in such manner as the board deems
fair and  equitable.  Expenses borne by the Trust include the following (or each
fund's share of the following):  (1) the cost (including  brokerage  commissions
and other transaction costs, if any) of securities purchased or sold by the fund
and any  losses  incurred  in  connection  therewith;  (2) fees  payable  to and
expenses  incurred  on behalf  of the fund by  PaineWebber;  (3)  organizational
expenses;  (4)  filing  fees  and  expenses  relating  to the  registration  and
qualification  of fund  shares  under  federal  and  state  securities  laws and
maintaining such registrations and qualifications; (5) fees and salaries payable
to the  trustees  and  officers  who are not  interested  persons of the fund or
PaineWebber;  (6)  all  expenses  incurred  in  connection  with  the  trustees'


                                       17

services,  including  travel  expenses;  (7)  taxes  (including  any  income  or
franchise   taxes)  and   governmental   fees;   (8)  costs  of  any  liability,
uncollectible  items of deposit and other insurance or fidelity  bonds;  (9) any
costs,  expenses or losses arising out of a liability of or claim for damages or
other relief asserted against the Trust or a fund for violation of any law; (10)
legal, accounting and auditing expenses, including legal fees of special counsel
for those trustees who are not interested  persons of the Trust; (11) charges of
custodians,  transfer agents and other agents;  (12) expenses of setting in type
and  printing   prospectuses  and  statements  of  additional   information  and
supplements  thereto,  reports and statements to shareholders and proxy material
for  existing  shareholders;  (13) costs of mailing  such  materials to existing
shareholders;  (14) any extraordinary expenses (including fees and disbursements
of counsel, costs of actions, suits or proceedings to which the Trust is a party
and the  expenses  the Trust may  incur as a result of its legal  obligation  to
provide  indemnification  to its officers,  trustees,  agents and  shareholders)
incurred by a fund; (15) fees, voluntary assessments and other expenses incurred
in connection with membership in investment company organizations; (16) costs of
mailing and tabulating proxies and costs of meetings of shareholders,  the board
and any committees  thereof;  (17) the cost of investment company literature and
other  publications  provided to the  trustees and  officers;  and (18) costs of
mailing, stationery and communications equipment.

        The Advisory and Mitchell Hutchins Contracts (collectively, "Contracts")
noted above provide that PaineWebber or Mitchell  Hutchins,  as the case may be,
shall not be liable for any error of  judgment or mistake of law or for any loss
suffered  by the funds in  connection  with the  performance  of the  Contracts,
except a loss resulting from willful misfeasance,  bad faith or gross negligence
on the part of PaineWebber or Mitchell Hutchins in the performance of its duties
or from reckless disregard of its duties and obligations thereunder.

        The  Contracts  are  terminable  by vote of the  funds'  board or by the
holders of a majority of the outstanding  voting  securities of the funds at any
time without  penalty,  on 60 days' written  notice to  PaineWebber  or Mitchell
Hutchins,  as the case may be. The Advisory Contract is also terminable  without
penalty by PaineWebber on 60 days' written notice to the Trust, and the Mitchell
Hutchins  Contract is  terminable  without  penalty by  PaineWebber  or Mitchell
Hutchins on 60 days' written notice to the other party. The Contracts  terminate
automatically  upon their  assignment,  and the Mitchell  Hutchins Contract also
automatically terminates upon the assignment of the Advisory Contract.

        During the fiscal year ended April 30, 1999,  the funds did not pay fees
to  PaineWebber  for its  services  as lending  agent  because the funds did not
engage in any securities lending activities.

        NET ASSETS.  The following  table shows the approximate net assets as of
July 31, 1999,  sorted by category of investment  objective,  of the  investment
companies as to which Mitchell  Hutchins  serves as adviser or  sub-adviser.  An

        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  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.

                                       18

        DISTRIBUTION  ARRANGEMENTS.  PaineWebber acts as the distributor of each
fund's  shares  under a  distribution  contract  with the  Trust  ("Distribution
Contract"),  which requires PaineWebber to use its best efforts, consistent with
its other business, to sell shares of the funds. Shares of the funds are offered
continuously.

        FINANCIAL INTERMEDIARIES.  Financial  intermediaries,  such as banks and
savings  associations,  may  purchase  Financial  Intermediary  shares  for  the
accounts of their customers.  The Trust has adopted a shareholder  services plan
("Plan") with respect to Financial  Intermediary shares.  PaineWebber implements
the Plan on behalf of the Trust by entering into a service  agreement  with each
financial intermediary that purchases Financial Intermediary shares requiring it
to provide  support  services to its customers who are the beneficial  owners of
Financial Intermediary shares.

        Under the Plan,  each fund pays  PaineWebber a monthly fee at the annual
rate of 0.25% of the average daily net asset value of the Financial Intermediary
shares held by financial intermediaries on behalf of their customers. Under each
service   agreement,   PaineWebber  pays  an  identical  fee  to  the  financial
intermediary  for providing the support  services to its customers  specified in
the  service  agreement.   These  services  may  include:  (i)  aggregating  and
processing  purchase and  redemption  requests  from  customers  and placing net
purchase and redemption orders with PaineWebber; (ii) providing customers with a
service  that  invests the assets of their  accounts in  Financial  Intermediary
shares;  (iii)  processing  dividend  payments  from  the  Trust  on  behalf  of
customers;  (iv) providing  information  periodically to customers showing their
positions in Financial  Intermediary  shares; (v) arranging for bank wires; (vi)
responding  to customer  inquiries  relating to the  services  performed  by the
financial intermediary; (vii) providing sub-accounting with respect to Financial
Intermediary shares beneficially owned by customers or the information necessary
for sub-accounting;  (viii) forwarding shareholder communications from the Trust
(such  as  proxies,  shareholder  reports  and  dividend,  distribution  and tax
notices) to customers,  if required by law; and (ix) such other similar services
as a fund may  reasonably  request from time to time to the extent the financial
intermediary is permitted to do so under federal and state  statutes,  rules and
regulations.  During  the  fiscal  year  ended  April 30,  1999,  the Trust made
payments  through  PaineWebber  to  financial  intermediaries  with  respect  to
Financial Intermediary shares in the amount of $24,898 for Money Market Fund, $0
for Government Securities Fund and $0 for Treasury Securities Fund.

        Under the terms of the service agreements,  financial intermediaries are
required to provide to their  customers a schedule of any  additional  fees that
they may charge  customers in  connection  with their  investments  in Financial
Intermediary  shares.  Financial  Intermediary shares are available for purchase
only by financial  intermediaries that have entered into service agreements with
PaineWebber  in  connection  with  their  investment.  Financial  intermediaries
providing  services to  beneficial  owners of Financial  Intermediary  shares in
certain  states may be required to be  registered  as dealers  under the laws of
those states.

        The  Plan  requires  that  PaineWebber  provide  to the  board  at least
annually a written report of the amounts  expended by PaineWebber  under service
agreements  with  financial  intermediaries  and the  purposes  for  which  such
expenditures   were  made.  Each  service   agreement   requires  the  financial
intermediary to cooperate with PaineWebber in providing information to the board
with  respect  to amounts  expended  and  services  provided  under the  service
agreement.  The Plan may be terminated at any time, without penalty,  by vote of
the  trustees  of the Trust  who are not  "interested  persons"  of the Trust as
defined  in the  Investment  Company  Act and who  have no  direct  or  indirect
financial interest in the operation of the Plan ("Disinterested  Trustees"). Any
amendment to the Plan must be approved by the board and any  material  amendment
must be approved by the Disinterested Trustees.

        Should future legislative, judicial or administrative action prohibit or
restrict  the  activities  of  banks  serving  as  financial  intermediaries  in
connection with the provision of support services to their customers,  the Trust
and  PaineWebber  might be required to alter or discontinue  their  arrangements
with financial intermediaries and change their method of operations with respect
to Financial  Intermediary  shares.  It is not  anticipated,  however,  that any
change in the Trust's method of operations would affect its net asset values per
share or result in a financial loss to any shareholder.



                                       19

        Conflict of interest restrictions may apply to a financial institution's
receipt  of  compensation  from a  fund  through  PaineWebber  under  a  service
agreement   resulting   from   fiduciary   funds  being  invested  in  Financial
Intermediary shares. Before investing fiduciary funds in Financial  Intermediary
shares, financial intermediaries,  including investment advisers and other money
managers  under the  jurisdiction  of the SEC, the  Department of Labor or state
securities  commissions  and banks  regulated by the Comptroller of the Currency
should consult their legal advisors.

                             PORTFOLIO TRANSACTIONS

        The funds purchase portfolio securities from dealers and underwriters as
well as from issuers.  Securities are usually traded on a net basis with dealers
acting as principal for their own accounts without a stated  commission.  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.  When  securities are purchased  directly
from an issuer,  no  commissions  or discounts  are paid.  When  securities  are
purchased in underwritten offerings, they include a fixed amount of compensation
to the  underwriter.  During  the last  three  fiscal  years,  the funds paid no
brokerage commissions.

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

        Research  services and information  received from brokers or dealers are
supplemental to Mitchell Hutchins' own research efforts and, when utilized,  are
subject to internal  analysis before being  incorporated  into their  investment
processes.  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 in advising  other  funds or  accounts  and,  conversely,
research  services  furnished  to  Mitchell  Hutchins  by  brokers or dealers in
connection  with other funds or accounts that either of them advises may be used
in advising the funds.

        Investment  decisions  for the funds and for other  investment  accounts
managed by Mitchell  Hutchins 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  the  funds  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 the funds and such
other  account(s) as to amount  according to a formula  deemed  equitable to the
funds 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 its ability to complete its entire order, in other cases
it is  believed  that  coordination  and the  ability to  participate  in volume
transactions will be beneficial to the funds.

                  ADDITIONAL INFORMATION REGARDING REDEMPTIONS

        Each fund 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 the 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 each fund's portfolio at the time; although the
funds attempt to maintain a constant net asset value of $1.00 per share.

        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.  If
payment is made in securities,  the shareholder may incur brokerage  expenses in
converting  these  securities into cash. The Trust is obligated to redeem shares
solely in cash up to the lesser of  $250,000  or 1% of the net asset  value of a
fund during any 90-day period for a shareholder.

                               VALUATION OF SHARES

        Money  Market  Fund's net asset value per share is  determined  by State
Street Bank and Trust Company ("State Street") as of noon and 2:30 p.m., Eastern
time, on each Business Day. Government Securities Fund's and Treasury Securities
Fund's net asset  values per share are  determined  by State  Street as of noon,
Eastern time, on each Business Day. As defined in the Prospectus, "Business Day"
means any day on which the Massachusetts  offices of State Street and the funds'
transfer agent, First Data Investor Services Group, Inc.  ("Transfer Agent") and
the New York City offices of PaineWebber and PaineWebber's bank are all open for
business.  One or more of these institutions will be closed on the observance of
the following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents'
Day,  Good Friday,  Memorial Day,  Independence  Day,  Labor Day,  Columbus Day,
Veterans' Day, Thanksgiving Day and Christmas Day.

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

        The board has  established  procedures  for the purpose of maintaining a
constant  net asset  value of $1.00  per  share,  which  include a review of the
extent of any deviation of net asset value per share,  based on available market
quotations,  from the $1.00 amortized cost per share. If that deviation  exceeds
1/2 of 1% for each fund,  the board will  promptly  consider  whether any action


                                       21
<PAGE>


should be initiated to  eliminate  or reduce  material  dilution or other unfair
results to  shareholders.  Such  action may  include  redeeming  shares in kind,
selling  portfolio  securities  prior  to  maturity,   reducing  or  withholding
dividends  and  utilizing  a net asset  value per share as  determined  by using
available market quotations.  Each fund will maintain a dollar-weighted  average
portfolio  maturity  of 90 days or less  and will not  purchase  any  instrument
having,  or deemed to have,  a remaining  maturity  of more than 397 days,  will
limit portfolio  investments,  including  repurchase  agreements,  to those U.S.
dollar-denominated  instruments that are of high quality under the Rule and that
Mitchell Hutchins, acting pursuant to the procedures, determines present minimal
credit  risks,  and  will  comply  with  certain   reporting  and  recordkeeping
procedures.  There is no assurance  that constant net asset value per share will
be maintained.  If amortized cost ceases to represent fair value per share,  the
board will take appropriate action.

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

                             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 will fluctuate.

        TOTAL  RETURN   CALCULATIONS.   Average   annual  total  return   quotes
("Standardized  Return")  used in each  fund's  Performance  Advertisements  are
calculated according to the following formula:

         P(1 + T)n(SUPERSCRIPT)   =       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. All dividends are assumed to have been reinvested at net asset value.

        The funds may also advertise other  performance  data, which may consist
of the annual or cumulative  return  (including net short-term  capital gain, if
any) earned on a hypothetical  investment in each fund since it began operations
or for shorter periods.  This return data may or may not assume  reinvestment of
dividends (compounding).

        CALCULATION OF YIELD.  Each fund computes its yield and effective  yield
quotations using  standardized  methods required by the SEC. A fund from time to
time  advertises  (1) its  current  yield  based on a recently  ended  seven-day
period, computed by determining the net change, exclusive of capital changes, in
the value of a hypothetical  pre-existing  account having a balance of one share
at the beginning of the period,  subtracting a  hypothetical  charge  reflecting
deductions from that shareholder  account,  dividing the difference by the value


                                       23
<PAGE>

of the  account at the  beginning  of the base  period to obtain the base period
return  and then  multiplying  the  base  period  return  by  (365/7),  with the
resulting yield figure carried to at least the nearest hundredth of one percent;
and (2) its effective  yield based on the same  seven-day  period by compounding
the base period  return by adding 1, raising the sum to a power equal to (365/7)
and subtracting 1 from the result, according to the following formula:

              EFFECTIVE YIELD = [(BASE PERIOD RETURN + 1)365/7(SUPERSCRIPT)] - 1

        Yield may fluctuate  daily and does not provide a basis for  determining
future yields. Because the yield of each fund fluctuates,  it cannot be compared
with yields on savings accounts or other investment alternatives that provide an
agreed to or guaranteed fixed yield for a stated period of time. However,  yield
information may be useful to an investor  considering  temporary  investments in
money market  instruments.  In  comparing  the yield of one money market fund to
another,  consideration  should  be given to each  fund's  investment  policies,
including the types of investments  made, the average  maturity of the portfolio
securities and whether there are any special account charges that may reduce the
yield.

        The  following  table  shows  the  yield  and  effective  yield  for the
outstanding shares of each fund for the 7-day period ended April 30, 1999:

                                                      YIELD    EFFECTIVE YIELD

        OTHER INFORMATION. The funds' performance data quoted in advertising and
other  promotional  materials  ("Performance   Advertisements")  represent  past
performance  and are not  intended to predict or indicate  future  results.  The
return  on  an  investment  in  each  fund  will   fluctuate.   In   Performance
Advertisements, the funds may compare their yields with data published by Lipper
Analytical   Services,   Inc.  for  money  funds   ("Lipper"),   CDA  Investment
Technologies,  Inc.  ("CDA"),  IBC Financial  Data, Inc.  ("IBC"),  Wiesenberger
Investment  Companies Service  ("Wiesenberger")  or Investment Company Data Inc.
("ICD"),  or with  the  performance  of  recognized  stock  and  other  indexes,
including the Standard & Poor's 500 Composite  Stock Price Index,  the Dow Jones
Industrial  Average,  the Morgan Stanley Capital  International World Index, the
Lehman Brothers  Treasury Bond Index,  the Lehman Brothers  Government/Corporate
Bond Index,  the Salomon Smith Barney  Government  Bond Index and changes in the
Consumer Price Index as published by the U.S. Department of Commerce.  The funds
also may refer in such materials to mutual fund  performance  rankings and other
data, such as comparative  asset,  expense and fee levels,  published by Lipper,
CDA, IBC,  Wiesenberger  or ICD.  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 also compare their  performance  with the  performance  of
bank  certificates  of deposit  ("CDs") as  measured by the CDA  Certificate  of
Deposit Index and the Bank Rate Monitor National Index and the average of yields
of CDs of major banks published by Banxquotes(R)  Money Markets.  In comparing a
fund's  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.  Bank accounts are insured in whole or in part by an
agency of the U.S.  government and may offer a fixed rate of return. Fund shares
are not insured or guaranteed by the U.S.  government  and returns  thereon will
fluctuate.  While the funds seek to  maintain a stable net asset  value of $1.00
per share, there can be no assurance that they will be able to do so.

        The funds may include  discussions  or  illustrations  of the effects of
compounding  in  Performance  Advertisements.  "Compounding"  refers to the fact
that,  if dividends on the funds'  investments  are  reinvested by being paid in
additional fund shares, any future income of the funds would increase the value,
not only of the original  funds'  investments,  but also of the additional  fund
shares  received  through  reinvestment.  As a result,  the value of the  funds'
investments would increase more quickly than if dividends had been paid in cash.
The funds may also make available to shareholders a daily accrual factor or "mil
rate" representing  dividends accrued to shareholder  accounts on a given day or
days. Certain shareholders may find that this information facilitates accounting
or recordkeeping.

                                      TAXES

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

        QUALIFICATION AS A REGULATED  INVESTMENT COMPANY. To continue to qualify
for  treatment  as a regulated  investment  company  ("RIC")  under the Internal
Revenue Code, the 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 and net short-term  capital gains,  if any) and must meet
several additional requirements. Among these requirements are 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 and certain other income; (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 that are 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 (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 the fund failed to qualify for  treatment  as a RIC
for any taxable  year,  (a) it would be taxed as an  ordinary  Trust 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 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

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

        CLASS OF SHARES.  A share of each class of a fund represents an interest
in the fund's  investment  portfolio  and has  similar  rights,  privileges  and
preferences.  Each share of a fund has equal  voting,  dividend and  liquidation
rights,  except that beneficial owners of Financial  Intermediary shares receive
certain  services  directly from financial  intermediaries  and bear the related
service costs.

                                       25
<PAGE>

        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 the Trust may elect all its board  members.  The shares of a fund
will be voted together,  except that only the shareholders of a particular class
may vote on matters  affecting only that class. The shares of each series of the
Trust  will  be  voted  separately,  except  when an  aggregate  vote of all the
securities is required by law. Financial intermediaries holding shares for their
own accounts must  undertake to vote the shares in the same  proportions  as the
vote of shares held for their customers.

        The Trust  does not hold  annual  meetings.  There  normally  will be no
meetings of  shareholders  to elect trustees unless fewer than a majority of the
trustees  holding  office have been  elected by  shareholders.  Shareholders  of
record  holding no less than two thirds of the  outstanding  shares of the Trust
may remove a board member 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  record of at least 10% of the
outstanding shares of the Trust.

        CUSTODIAN;  TRANSFER  AND  DIVIDEND  AGENT.  State Street Bank and Trust
Company,  located at One Heritage Drive, North Quincy,  Massachusetts  02171, is
custodian of the funds' assets.  First Data Investor Services Group, Inc., whose
principal  business address is 4400 Computer Drive,  Westborough,  Massachusetts
01581-5159, is the funds' transfer and dividend disbursing agent.

        COUNSEL.  The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts
Avenue,  N.W.,  Washington,  D.C.  20036-1800,  serves as  counsel to the funds.
Kirkpatrick  & Lockhart  LLP also acts as counsel to  PaineWebber  and  Mitchell
Hutchins in connection with other matters.

        AUDITORS.  Ernst & Young LLP,  787 Seventh  Avenue,  New York,  New York
10019, serves as independent auditors for the funds.
