       Brown Brothers  Harriman & Co. provides four funds for investor's  liquid
assets.  They range from a U.S Treasury Fund with maximum safety of principal to
a Tax Free  Short/Intermediate  Fixed Income Fund that has  potential  for price
volatility.

        The net asset value of shares of each of the Money Market Fund, the U.S.
Treasury Money Fund and the Tax Exempt Money Fund is expected to remain constant
at $1.00 by investing in securities with a maturity of 13 months or less, and by
maintaining a  dollar-weighted  average  maturity of 90 days or less.  The share
price of the Tax Free  Short/Intermediate  Fixed Income Fund changes daily based
on market conditions.

INVESTMENT STRATEGIES

                            U.S. Treasury Money Fund

       The  Investment  Adviser of the U.S.  Treasury Money Fund invests only in
securities  backed as to principal  and interest  payments by the full faith and
credit of the United States of America.  These securities are issues of the U.S.
Treasury,  such as bills, notes and bonds as well as other full faith and credit
obligations of the U.S. Government.

                                Money Market Fund

       The Money Market Fund invests all of its assets in the U.S.  Money Market
Portfolio,  an investment  company that has the same  objective as the Fund. The
Investment  Adviser  of  the  Portfolio  invests  only  in  the  highest  rated,
short-term  money  market  instruments   denominated  in  U.S.  dollars.   These
instruments include U.S. Government  securities and bank obligations of U.S. and
non-U.S.  banks  (such as  certificates  of  deposit,  fixed time  deposits  and
bankers'  acceptances),   commercial  paper,   repurchase  agreements,   reverse
repurchase agreements, when-issued and delayed delivery securities, bonds issued
by U.S. corporations and obligations of certain supranational organizations.

                              Tax Exempt Money Fund

       The  Investment  Adviser  invests  at least 80% of the  Fund's  assets in
municipal securities the interest on which is exempt from federal income tax and
alternative  minimum  tax.  Municipal  securities  may  be  fully  or  partially
guaranteed. They may be guaranteed by the local government or by the credit of a
private  issuer.  Municipal  securities may also be guaranteed by the current or
anticipated  revenues from a specific project or specific assets.  Additionally,
municipal securities may be guaranteed by domestic or foreign entities providing
credit  support  such  as  letters  of  credit,  guarantees  or  insurance.  The
Investment  Adviser  may  invest  more than 25% of the  Fund's  total  assets in
securities that finance similar  projects,  such as those relating to education,
health care, transportation and utilities.

                  Tax Free Short/Intermediate Fixed Income Fund

         The Tax Free Short/Intermediate  Fixed Income Fund invests primarily in
a broad range of high  quality  municipal  securities  issued by or on behalf of
states,  territories  and  possessions  of the United  States,  the  District of
Columbia  and  their  subdivisions,   agencies  and   instrumentalities.   These
securities  include  municipal  bonds,  notes,  commercial  paper,  variable and
floating rate instruments and when-issued and delayed delivery  securities.  The
dollar weighted  average  maturity of the Fund's portfolio does not exceed three
years.


PRINCIPAL RISK
FACTORS
      The  principal  risks of investing  in each Fund are  described  below.  A
shareholder may lose money by investing in the Funds. Market Risk, Interest Rate
Risk and  Credit  Risk  discussed  below  are  applicable  to each  Fund and the
Portfolio.
o        Market Risk:
      The price of a debt security will fluctuate in response to changes in
interest rates.

o        Interest Rate Risk:
      The amount of income paid to the  shareholder  by each Fund will fluctuate
depending on day-to-day variations in short-term interest rates. In general, the
prices of debt  securities  fall when  interest  rates rise.  The Tax Free Fixed
Income Fund invests in longer term obligations  which are usually more sensitive
to interest rate changes than the  shorter-term  obligations  in which the money
market funds invest.

o        Credit Risk:
      Credit  risk  refers to the  likelihood  that an issuer  will  default  on
interest or principal payments. Changes in the financial condition of an issuer,
changes in specific  economic or political  conditions  that affect a particular
type of issuer,  and changes in general  economic or  political  conditions  can
adversely affect the credit quality or value of an issuer's securities. Entities
providing credit support or a maturity-shortening structure also can be affected
by these types of changes. Municipal securities backed by current or anticipated
revenues from a specific  project or specific assets can be negatively  affected
by the  discontinuance  of the taxation  supporting the project or assets or the
inability  to  collect  revenues  for the  project  or  from  the  assets.  If a
security's  structure  fails to function as intended,  the security could become
taxable or  decline  in value.  Because  the Funds may  invest  their  assets in
municipal  securities of issuers financing similar type projects,  the Funds may
be adversely affected by a particular economic or political event affecting that
type  project.  Because the U.S.  Money Market  Portfolio  invests a significant
portion of its assets in bank  obligations,  the value of these  investments and
the net assets of the Portfolio  could decline more  dramatically as a result of
adverse events affecting the bank industry.

                                Money Market Fund

o        Foreign Investment Risk:
     Because the U.S.  Money Market  Portfolio  invests in securities  issued by
     non-U.S.  banks,  the  Portfolio  is subject to  additional  risks on these
     securities  such as adverse  political,  social and  economic  developments
     abroad, different kinds and levels of market and issuer regulations and the
     different  characteristics of overseas economies and markets.  There may be
     rapid changes in the values of these securities.

      Investments  in each Fund are neither  insured nor  guaranteed by the U.S.
Government.  Shares  of each  Fund  are  not  deposits  or  obligations  of,  or
guaranteed by, Brown  Brothers  Harriman & Co. or any other bank, and the shares
are not  insured by the  Federal  Deposit  Insurance  Corporation,  the  Federal
Reserve Board or any other federal, state or other governmental agency. Although
the Money Market Fund,  U.S.  Treasury Money Fund and Tax Exempt Money Fund seek
to preserve the value of your  investment at $1.00 per share,  it is possible to
lose money by investing in each Fund.

Fund Performance

      The chart and table below give an  indication of the risks of investing in
the Money Market Fund, U.S. Treasury Money Fund and Tax Free  Short/Intermediate
Fixed Income Fund. The chart shows changes in each Fund's  performance from year
to year. The table shows how the Tax Free Short/Intermediate Fixed Income Fund's
average  annual returns for the periods  indicated  compared to those of a broad
measure of market  performance.  The US Money Market Fund provided  shareholders
greater return than the US Treasury Money Fund with the same volatility.  The US
Treasury  Fund,  however,  is the safest credit risk. The return on the Tax Free
Short/Intermediate  Fixed Income Fund are  generally  free from  Federal  income
taxes,  while the returns on the Money Market Fund and U.S.  Treasury Money Fund
are subject to Federal income taxes. For current yield information,  please call
800-625-5759 toll free, or contact your account representative.

      When  you  consider  this  information,  please  remember  that  a  Fund's
performance  in past  years is not an  indication  of how a Fund  will do in the
future.

      Since  the Tax  Exempt  Money  Fund has not been in  existence  for a full
calendar year, bar chart and table information is not included.

                                     EXAMPLE

     This example is intended to help an investor  compare the cost of investing
in the Funds to the cost of investing in other mutual funds. The example assumes
that an investor  invests  $10,000 in a Fund for the time periods  indicated and
then  sells all of his  shares at the end of those  periods.  The  example  also
assumes  that an  investment  has a 5%  return  each  year and  that the  Funds'
operating expenses remain the same as shown in the table above.  Although actual
costs  on an  investor's  investment  may be  higher  or  lower,  based on these
assumptions the investor's costs would be:

SHAREHOLDER INFORMATION
                                 NET ASSET VALUE

       The Trust  determines  the net asset value of each Fund every day the New
York Stock  Exchange is open for regular  trading and the Federal  Reserve banks
are open for business.  The Money Market Fund, U.S.  Treasury Money Fund and Tax
Exempt Money Fund each calculate their net asset value once daily at 12:00 P.M.,
New York time. The Tax Free Short/Intermediate  Fixed Income Fund calculates its
net asset value once daily at 4:00 P.M.,  New York time.  Net asset value is the
value of a single share of a Fund.

       It is anticipated  that the net asset value per share of the Money Market
Fund, U.S. Treasury Money Fund and Tax Exempt Money Fund will remain constant at
$1.00. No assurance can be given that this goal can be achieved.

       The Trust values the assets of the U.S.  Treasury  Money Fund, Tax Exempt
Money Fund and the Portfolio at amortized cost, which is approximately  equal to
market  value.  The Trust  values the assets in the Tax Free  Short/Intermediate
Fixed  Income  Fund's  portfolio  on the basis of their  market  quotations  and
valuations  provided by  independent  pricing  services.  If quotations  are not
readily available,  the assets of the Tax Free  Short/Intermediate  Fixed Income
Fund are valued at fair value in accordance with  procedures  established by the
Trustees of the Trust.

                               PURCHASE OF SHARES

       The Trust  offers  shares of each Fund on a  continuous  basis at its net
asset value  without a sales charge.  The Trust  reserves the right to determine
the purchase orders for Fund shares that it will accept.  Investors may purchase
shares on any day the net asset value is  calculated  if the Trust  receives the
purchase  order,  including  acceptable  payment for such  order,  prior to such
calculation.  The Trust then executes  purchases of Fund shares at the net asset
value per share next determined.  Shares of the Money Market Fund, U.S. Treasury
Money Fund and Tax Exempt Money Fund are  entitled to dividends  declared on the
day the Trust executes the purchase  order on the books of the Trust.  Shares of
the Tax Free  Short/Intermediate  Fixed  Income Fund are  entitled to  dividends
declared on the next  business  day  following  the day the Trust  executes  the
purchase order on the books of the Trust.

       An  investor  who  has an  account  with  an  Eligible  Institution  or a
Financial  Intermediary  may place purchase  orders for Fund shares through that
Eligible Institution or Financial  Intermediary,  which holds such shares in its
name on behalf of that  customer  pursuant to  arrangements  made  between  that
customer and that Eligible Institution or Financial Intermediary.  Each Eligible
Institution and each Financial Intermediary may establish and amend from time to
time a minimum  initial and a minimum  subsequent  purchase  requirement for its
customers.  Currently,  such minimum purchase  requirements range from $1,000 to
$5,000. Each Eligible Institution or Financial Intermediary arranges payment for
Fund shares on behalf of its customers.  An Eligible  Institution or a Financial
Intermediary may charge a transaction fee on the purchase of Fund shares.

       An investor who does not have an account with an Eligible  Institution or
a Financial  Intermediary  must place  purchase  orders for Fund shares with the
Trust through Brown Brothers  Harriman & Co., the Fund's  Shareholder  Servicing
Agent.  Such an investor has such shares held directly in the investor's name on
the books of the Trust and is  responsible  for arranging for the payment of the
purchase  price of Fund  shares.  The Trust  executes  all  purchase  orders for
initial  and  subsequent  purchases  at the  net  asset  value  per  share  next
determined after the Trust's Custodian,  State Street Bank and Trust Company has
receive  payment in the form of a cashier's  check drawn on a U.S. bank, a check
certified by a U.S. bank or a wire transfer. The Shareholder Servicing Agent has
established a minimum initial purchase requirement for each Fund of $100,000 and
a  minimum  subsequent  purchase  requirement  for  each  Fund of  $25,000.  The
Shareholder  Servicing Agent may amend these minimum purchase  requirements from
time to time.

                              REDEMPTION OF SHARES

       The Trust  executes your  redemption  request at the next net asset value
calculated after the Trust receives your redemption request. Shares of the Money
Market Fund, U.S. Treasury Money Fund and Tax Exempt Money Fund continue to earn
daily  dividends  declared prior to the business day that the Trust executes the
redemption  request  on  the  books  of  the  Trust.  Shares  of  the  Tax  Free
Short/Intermediate Fixed Income Fund continue to earn dividends declared through
the business day that the Trust executes the redemption  request on the books of
the Trust.
       Shareholders  must redeem  shares held by an  Eligible  Institution  or a
Financial  Intermediary on behalf of such  shareholder  pursuant to arrangements
made  between  that  shareholder  and that  Eligible  Institution  or  Financial
Intermediary.  The Trust pays  proceeds of a  redemption  to that  shareholder's
account  at  that  Eligible  Institution  or  Financial  Intermediary  on a date
established by the Eligible Institution or Financial  Intermediary.  An Eligible
Institution  or a Financial  Intermediary  may charge a  transaction  fee on the
redemption of Fund shares.

       Shareholders may redeem shares held directly in the name of a shareholder
on the books of the Trust by  submitting a  redemption  request in good order to
the Trust  through the  Shareholder  Servicing  Agent.  The Trust pays  proceeds
resulting  from such  redemption  directly to  shareholders  of the Money Market
Fund,  U.S.  Treasury  Money Fund and Tax Exempt Money Fund generally on the day
the  redemption  request is executed,  and in any event  within seven days.  The
Trust pays proceeds  resulting from such redemption  directly to shareholders of
the Tax Free Short/Intermediate Fixed Income Fund generally on the next business
day after the  redemption  request is  executed,  and in any event  within seven
days.

        A shareholder  redeeming shares should be aware that the net asset value
of the shares of the Money Market Fund, U.S.  Treasury Money Fund and Tax Exempt
Money  Fund may,  in  unusual  circumstances,  decline  below  $1.00 per  share.
Accordingly, a redemption request may result in payment of a dollar amount which
differs from the number of shares redeemed.

                            Redemptions by the Trust

       The Shareholder Servicing Agent has established a minimum account size of
$100,000 for the Funds,  which may be amended from time to time. If the value of
a  shareholder's  holdings  in a Fund  falls  below  that  amount  because  of a
redemption of shares,  the Trust may redeem the shareholder's  remaining shares.
If such remaining shares are to be redeemed,  the Trust notifies the shareholder
and allows the shareholder 60 days to make an additional  investment to meet the
minimum   requirement   before  the  redemption  is  processed.   Each  Eligible
Institution and each Financial Intermediary may establish and amend from time to
time for their  respective  customers a minimum  account size,  each of which is
currently lower than that established by the Shareholder Servicing Agent.

                         Further Redemption Information

       Redemptions  of shares  are  taxable  events on which a  shareholder  may
realize a gain or a loss.

       The Trust may  suspend a  shareholder's  right to  receive  payment  with
respect to any redemption or postpone the payment of the redemption proceeds for
up to seven days and for such other periods as applicable law may permit.

                           DIVIDENDS AND DISTRIBUTIONS

       The net  income  and  short-term  capital  gains and  losses of the Money
Market Fund,  U.S.  Treasury  Money Fund and Tax Exempt Money Fund,  if any, are
declared  as  a  dividend   daily  and  paid  monthly.   All  of  the  Tax  Free
Short/Intermediate Fixed Income Fund's net investment income and a discretionary
portion of any net short-term capital gains are declared as a dividend daily and
paid monthly.

        Determination  of each  Fund's  net  income  is made each  business  day
immediately  prior to the determination of the net asset value per share of each
Fund.  Net income for days other than such  business  days is  determined at the
time of the  determination  of the net asset value per share of each Fund on the
immediately preceding business day.

       Each Eligible  Institution and each Financial  Intermediary may establish
its own policy with respect to the  reinvestment of dividends in additional Fund
shares.

       Dividends  declared are payable to shareholders of record of the Funds on
the date of  determination.  For the Money Market Fund, U.S. Treasury Money Fund
and Tax Exempt Money Fund,  shares  purchased  through  submission of a purchase
order prior to 12:00 P.M.,  New York time on such a business  day begin  earning
dividends on that business day. Shares redeemed do not qualify for a dividend on
the  business  day  that  the   redemption   is  executed.   For  the  Tax  Free
Short/Intermediate  Fixed Income Fund, shares purchased through  submission of a
purchase  order prior to 4:00 P.M.,  New York time on such a business  day begin
earning  dividends on the next  business day.  Shares  redeemed do qualify for a
dividend  on the  business  day  that  the  redemption  is  executed.  Unless  a
shareholder  whose  shares are held  directly in the  shareholder's  name on the
books  of  the  Trust  elects  to  have   dividends  paid  in  cash,  the  Trust
automatically reinvests dividends in additional Fund shares without reference to
the minimum subsequent purchase requirement.

       Such  shareholder  who elects to have  dividends  paid in cash receives a
check in the amount of such  dividends.  In the event a shareholder  redeems all
shares held at any time during the month,  all accrued but unpaid  dividends are
included in the  proceeds of the  redemption  and future  purchases of shares by
such shareholder will be subject to the minimum initial purchase requirements.

       Substantially all of the Tax Free Short/Intermediate  Fixed Income Fund's
realized  net  long-term  capital  gains,  if  any,  are  declared  and  paid to
shareholders on an annual basis as a capital gains  distribution.  The Trust may
make an additional dividend and/or capital gains distribution in a given year to
the extent necessary to avoid the imposition of federal excise tax on the Fund.

                                      TAXES

       Dividends of net income and net  short-term  capital  gains,  if any, are
taxable to shareholders of the Money Market Fund and U.S. Treasury Money Fund as
ordinary  income,  whether  such  dividends  are paid in cash or  reinvested  in
additional shares.

       The Tax  Exempt  Money  Fund  and the Tax Free  Short/Intermediate  Fixed
Income  Fund  expect  that  most of their net  income  will be  attributable  to
interest on municipal  obligations and as a result most of the Funds'  dividends
to  shareholders  will not be taxable.  The non-exempt  portion of dividends are
taxable to shareholders of the Funds as ordinary income,  whether such dividends
are paid in cash or reinvested in additional shares.

       The Tax Free  Income  Fund's  capital  gains may be taxable at  different
rates  depending on the length of time the Fund holds its assets.  Capital gains
distributions  are taxable to shareholders as long-term  capital gains,  whether
paid in cash or reinvested in additional  shares and regardless of the length of
time a particular shareholder has held Fund shares.

         The treatment of each Fund and its  shareholders  in those states which
have income tax laws might differ from  treatment  under the federal  income tax
laws.  Therefore,  distributions  to  shareholders  may be subject to additional
state and local  taxes.  Shareholders  are urged to consult  their tax  advisors
regarding any state or local taxes.

                                Foreign Investors

       Each Fund is designed for investors who are either citizens of the United
States or aliens subject to United States income tax. Prospective  investors who
are not citizens of the United  States and who are not aliens  subject to United
States  income tax are subject to United  States  withholding  tax on the entire
amount of all  dividends.  Therefore,  such  investors  should not invest in the
Funds  since  alternative  investments  would not be  subject  to United  States
withholding tax.

       The financial highlights table is intended to help an investor understand
the financial  performance of the Funds.  Certain information reflects financial
results for a single Fund share.  The total returns in the tables  represent the
rate that an investor  would have earned on an investment in each Fund (assuming
reinvestment  of all dividends and  distributions).  This  information  has been

ADDITIONAL INVESTMENT INFORMATION

                                Money Market Fund

       Investment Structure. The Trust seeks to achieve the investment objective
of the Money Market Fund by investing all of the Fund's assets in the Portfolio,
a diversified  open-end investment company having the same investment  objective
as the Fund.  Other mutual funds or  institutional  investors  may invest in the
Portfolio on the same terms and  conditions  as the Fund.  However,  these other
investors may have different  operating  expenses  which may generate  different
aggregate  performance  results. The Trust may withdraw the Fund's investment in
the Portfolio at any time as a result of changes in the  Portfolio's  investment
objective,  policies or restrictions or if the Board of Trustees determines that
it is otherwise in the best interests of the Fund to do so.

       U.S. Government Securities. The Portfolio may invest in securities issued
or guaranteed by the U.S. Government,  its agencies or instrumentalities.  These
securities,  including  those  which  are  guaranteed  by  federal  agencies  or
instrumentalities,  may or may not be backed by the "full  faith and  credit" of
the United States.

       Bank  Obligations.  The Portfolio  may invest in U.S.  dollar-denominated
high quality  securities.  These securities include  negotiable  certificates of
deposit, fixed time deposits and bankers' acceptances of banks, savings and loan
associations  and savings banks organized under the laws of the United States or
any state  thereof.  The  Portfolio's  investments  also include  obligations of
non-U.S.  branches of such banks, or of non-U.S. banks or their U.S. or non-U.S.
branches.  (The Portfolio may only invest in obligations of such non-U.S.  banks
if such bank has more than $500 million in total assets,  and has an outstanding
short-term  debt issue rated within the highest  rating  category for short-term
debt  obligations  by at  least  two  (unless  only  rated  by  one)  nationally
recognized  statistical  rating  organizations  (e.g.,  Moody's  and  S&P).  The
Portfolio  may  invest  in  unrated  obligations  of  non-U.S.   banks  if  such
obligations are of comparable quality as determined by or under the direction of
the Portfolio's Board of Trustees.)

       Commercial  Paper. The Portfolio may invest in commercial paper including
variable  rate demand  master notes issued by U.S.  corporations  or by non-U.S.
corporations  which are direct  parents or  subsidiaries  of U.S.  corporations.
Master notes are demand  obligations  that permit the  investment of fluctuating
amounts at varying market rates of interest pursuant to arrangements between the
issuer and a U.S.  commercial bank acting as agent for the payees of such notes.
Master notes are callable on demand,  but are not  marketable to third  parties.
Consequently,  the right to redeem such notes depends on the borrower's  ability
to pay on  demand.  At the date of  investment,  commercial  paper must be rated
within the highest rating category for short-term  debt  obligations by at least
two  (unless  only  rated  by  one)  nationally  recognized  statistical  rating
organizations  (e.g., Moody's and S&P) or, if unrated, are of comparable quality
as determined by or under the direction of the Portfolio's Board of Trustees.

       Repurchase Agreements. The Portfolio may enter into repurchase agreements
for the  Portfolio  only with a "primary  dealer" (as  designated by the Federal
Reserve Bank of New York) in U.S. Government securities.  A repurchase agreement
is an  agreement  in which the seller  (the  "Lender")  of a security  agrees to
repurchase  from the Portfolio the security sold at a mutually  agreed upon time
and price.  As such,  it is viewed as the  lending of money to the  Lender.  The
Portfolio  always  receives  as  collateral   securities  which  are  issued  or
guaranteed by the U.S. Government, its agencies or instrumentalities.

       Other Obligations. Assets of the Portfolio may be invested in bonds, with
maturities not exceeding one year, issued by U.S. corporations which at the date
of investment are rated within the highest rating category for such  obligations
by at least two (unless  only rated by one)  nationally  recognized  statistical
rating  organizations  (e.g., Moody's and S&P) or, if unrated, are of comparable
quality as  determined  by or under the  direction of the  Portfolio's  Board of
Trustees.
       Assets  of the  Portfolio  may also be  invested  in  obligations  of the
International  Bank for Reconstruction and Development which may be supported by
appropriated but unpaid  commitments of its member countries,  although there is
no assurance that these  commitments will be undertaken in the future.  However,
assets of the Portfolio may not be invested in obligations of the Inter-American
Development Bank or the Asian Development Bank.

 U.S. Money Market Portfolio, U.S. Treasury Money Fund and Tax Exempt Money Fund

       The Investment Adviser invests all of the assets of the U.S. Money Market
Portfolio,  U.S.  Treasury  Money Fund and Tax Exempt  Money Fund in  securities
which  are  rated  within  the  highest  rating  category  for  short-term  debt
obligations  by at least two (unless  only rated by one)  nationally  recognized
statistical  rating  organizations   (e.g.,  Moody's  Investors  Service,   Inc.
("Moody's"),  Standard & Poor's  Corporation  ("S&P")) and Fitch or, if unrated,
are of  comparable  quality as determined by or under the direction of the Board
of Trustees of the Fund and the Portfolio.

     Tax Exempt Money Fund and Tax Free Short/Intermediate Fixed Income Fund

       The  following   information  describes  the  securities  each  Fund  may
purchase,  the  interest  on which is exempt  from  federal  income  tax and the
alternative minimum tax. However,  other such securities not mentioned below may
be purchased for each Fund if they meet the quality and maturity  guidelines set
forth in each Fund's investment policies.  Municipal Bonds. Municipal securities
are  issued to raise  money  for a  variety  of  public  and  private  purposes,
including general financing for state and local governments,  or financing for a
specific  project or public  facility.  Municipal  securities  provide  interest
income  that  is  exempt  from  regular  federal  income  tax,  other  than  the
alternative  minimum tax. They generally meet the  longer-term  capital needs of
their issuers and have maturities of one year or more. The Tax Exempt Money Fund
may  purchase  Municipal  Bonds with a  remaining  maturity of 397 days or less.
These securities include:
         -    General Obligation Bonds-bonds backed by the municipality's pledge
              of full faith, credit and taxing power.
         -    Revenue  Bonds-bonds  backed by the revenue of a specific project,
              facility or tax. These include  municipal  water,  sewer and power
              utilities;   transportation   projects;   education   or   housing
              facilities; industrial development and resource recovery bonds.
         -    Refunded Bonds-general  obligation or revenue bonds that have been
              fully secured or  collateralized by an "escrow fund" consisting of
              U.S. Government  obligations that can adequately meet interest and
              principal payments.
- -             Lease  Obligation  Bonds-bonds  backed by lease  obligations  of a
              state  or  local  authority  for the use of  land,  equipment  and
              facilities.  These securities are not backed by the full faith and
              credit  of the  municipality  and  may  be  riskier  than  general
              obligation bonds or revenue bonds.
- -             Asset-Backed   Bonds-bonds   secured  by  interests  in  pools  of
              municipal   purchase   contracts,   financing   leases  and  sales
              agreements.  These  obligations are  collateralized  by the assets
              purchased or leased by the municipality.
- -             Zero  Coupon  Bonds-securities  issued at a discount  from their
              face  value  that pay all  interest  and principal upon maturity.
- -          Participation  Certificates-variable rate demand instruments that the
           Tax  Exempt   Money   Fund  may   invest  in  include   Participation
           Certificates  purchased by such Fund from banks,  insurance companies
           or other financial institutions in fixed or variable rate, tax-exempt
           municipal obligations (expected to be focused in Revenue Bonds) owned
           by such  institutions  or affiliated  organizations.  A participation
           certificate  represents the sale by the bank of an undivided interest
           in  a  municipal  obligation  it  owns.  These  certificates  may  be
           supported by a bank letter of credit or guarantee.
       Other  Federal  Tax-Exempt   Obligations--Any  other  Federal  tax-exempt
obligations issued by or on behalf of states and municipal governments and their
authorities,  agencies,  instrumentalities  and  political  subdivisions,  whose
inclusion  in the Tax Exempt  Money Fund would be  consistent  with such  Fund's
"Investment  Objectives,  Policies  and Risks" and  permissable  under Rule 2a-7
under the Investment Company Act of 1940, as amended (the "1940 Act").

       Stand-by  Commitments--When the Tax Exempt Money Fund purchases Municipal
Obligations  it may also  acquire  stand-by  commitments  from  banks  and other
financial  institutions  with  respect to such  Municipal  Obligations.  Under a
stand-by  commitment,  a bank or broker-dealer agrees to purchase at such Fund's
option a  specified  Municipal  Obligation  at a  specified  price with same day
settlement.

       Municipal Notes. Debt obligations issued by states, local governments and
regional  authorities  which provide interest income that is exempt from regular
federal  income taxes,  other than the  alternative  minimum tax. They generally
meet the shorter-term capital needs of their issuers and have maturities of less
than one year. These securities include:

         -    Tax and Revenue Anticipation Notes-notes issued in expectation of
future taxes or revenues.
         -    Bond Anticipation Notes-notes issued in anticipation of the sale
of long-term bonds.
       Municipal Commercial  Paper-obligations issued to meet short-term working
       capital   or   operating    needs.    Variable    and    Floating    Rate
       Instruments-securities whose interest rates are reset daily, weekly or at
another  periodic  date so that the security  remains  close to par,  minimizing
changes in its market value.  These securities often have a demand feature which
entitles the investor to repayment of principal  plus accrued  interest on short
notice.
                                    Each Fund

       Year 2000  issue.  Information  technology  experts are  concerned  about
computer  systems'  ability to  process  data-related  information  on and after
January 1, 2000. This situation,  commonly known as the "Year 2000" issue, could
have an adverse impact on each Fund. The cost of addressing the Year 2000 issue,
if substantial,  could  adversely  affect  companies and governments  that issue
securities  held by each  Fund and the  Portfolio.  The  Investment  Adviser  is
addressing  the Year 2000 issue for its systems.  Each Fund has been informed by
its other service providers that they are taking similar measures. Although each
Fund does not  expect  the Year 2000 issue to  adversely  effect  it,  each Fund
cannot  guarantee that the efforts of each Fund, which are limited to requesting
and  receiving  reports  from its  services  providers,  or the  efforts  of its
services providers to correct the problem will be successful.
