MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES.

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)  U.S.  dollar-denominated  obligations issued or supported by the credit
         of U.S. or foreign banks or savings  institutions  with total assets of
         more than $1 billion (including obligations of foreign branches of such
         banks).

     2)  High  quality   commercial  paper  and  other  obligations   issued  or
         guaranteed  (or otherwise  supported) by U.S. and foreign  corporations
         and  other  issuers  rated (at the time of  purchase)  A-2 or higher by
         Standard  and Poor's,  Prime-2 or higher by  Moody's,  D-2 or higher by
         Duff & Phelps,  F-2 or  higher  by Fitch or TBW-2 or higher by  Thomson
         BankWatch,  as well as high quality corporate bonds rated AA (or Aa) or
         higher at the time of purchase by those rating  agencies.These  ratings
         must be provided by at least two rating agencies, or by the only rating
         agency providing a rating.

     3)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     4)  Asset-backed securities (including interests in pools of assets such as
         mortgages,   installment   purchase   obligations   and   credit   card
         receivables).

     5)  Securities  issued  or  guaranteed  by the  U.S.  Government  or by its
         agencies or authorities.

     6)  Dollar-denominated   securities   issued  or   guaranteed   by  foreign
         governments or their political subdivisions, agencies or authorities.

     7)  Securities issued or guaranteed by state or local governmental bodies.

     8)  Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                        6

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                        7

<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK / RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.25% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.97%.  Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                    1 YEAR          3 YEARS         5 YEARS         10 YEARS

MUNICIPAL MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

GENERAL  OBLIGATION BONDS: Bonds which are secured by the issuer's pledge of its
full faith, credit and taxing power for the payment of principal and interest.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

MUNICIPAL  LEASE  OBLIGATIONS:  These provide  participation  in municipal lease
agreements and installment  purchase contracts,  but are not part of the general
obligations of the municipality.

MUNICIPAL SECURITY: A short-term obligation issued by or on behalf of states and
possessions  of the  United  States,  their  political  subdivisions  and  their
agencies and authorities.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REVENUE  BONDS:  Bonds which are secured only by the revenues  from a particular
facility or class of  facilities,  such as a water or sewer system,  or from the
proceeds of a special excise tax or other revenue source.

TAX-EXEMPT COMMERCIAL PAPER:  Short-term Municipal Securities with maturities of
1 to 270 days.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate current income exempt from federal income taxes,
to provide you with liquidity and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve  this goal,  we invest in a  diversified  portfolio of Municipal
Securities. Specifically, we may invest in:

     1)  Fixed and  variable  rate notes and similar debt  instruments  rated or
         issued by issuers  who have  ratings at the time of  purchase of MIG-2,
         VMIG-2  or  Prime-2  or  higher  by  Moody's,  SP-2 or A-2 or higher by
         Standard & Poor's,  D-2 or higher by Duff & Phelps, or F-2 or higher by
         Fitch (or  guaranteed  or  otherwise  supported  by entities  with such
         ratings).

     2)  Tax-exempt  commercial  paper and  similar  debt  instruments  rated or
         issued by issuers  who have  ratings at the time of purchase of Prime-2
         or higher by Moody's, A-2 or higher by Standard & Poor's, D-2 or higher
         by Duff & Phelps, or F-2 or higher by Fitch (or guaranteed or otherwise
         supported by entities with such ratings).

     3)  Municipal bonds rated or issued by issuers who have ratings at the time
         of  purchase  of Aa or higher by Moody's or AA or higher by  Standard &
         Poor's, Duff & Phelps or Fitch (or guaranteed or otherwise supported by
         entities with such ratings).

     4)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     5)  Municipal  bonds and notes whose  principal  and interest  payments are
         guaranteed by the U.S. Government or one of its agencies or authorities
         or which otherwise depend on the credit of the United States.

     The fund seeks to maintain a net asset value of $1.00 per share.

     We normally  invest at least 80% of its net assets in Municipal  Securities
and other  instruments  whose  interest  is exempt  from  federal  income tax or
subject to the Federal Alternative Minimum Tax.

     The fund may hold  uninvested  cash  reserves  during  temporary  defensive
periods or, if in our opinion suitable  Municipal  Securities are not available.
The fund may hold all of its assets in uninvested cash reserves during temporary
defensive periods. Uninvested cash will not earn income.

     We  intend  to have no more  than  25% of its  total  assets  in  Municipal
Securities of issuers located in the same state.

                                       11

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain variable and floating rate  instruments)
will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Municipal  Securities  include revenue bonds,  general obligation bonds and
municipal lease obligations. Revenue bonds include private activity bonds, which
are not payable  from the general  revenues  of the  issuer.  Consequently,  the
credit  quality of private  activity  bonds is usually  directly  related to the
credit  standing of the corporate user of the facility  involved.  To the extent
that the fund's assets are invested in private  activity bonds, the fund will be
subject to the particular  risks  presented by the laws and economic  conditions
relating to such projects and bonds to a greater  extent than if its assets were
not so invested.  Moral  obligation bonds are normally issued by special purpose
public authorities. If the issuer of moral obligation bonds is unable to pay its
debts from current  revenues,  it may draw on a reserve fund the  restoration of
which is a moral but not a legal  obligation of the state or municipality  which
created  the  issuer.  Risk  exists  that a  municipality  will not honor  moral
obligation  bonds.  Municipal lease obligations are not guaranteed by the issuer
and are generally less liquid than other securities.

     There may be less  information  available  on the  financial  condition  of
issuers of Municipal  Securities  than for public  corporations.  The market for
municipal  bonds may be less liquid than for taxable  bonds.  This means that it
may be harder to buy and sell Municipal Securities, especially on short notice.

     The fund may invest in bonds whose  interest  may be subject to the Federal
Alternative  Minimum Tax. Interest received on these bonds by a taxpayer subject
to the Federal Alternative Minimum Tax is taxable.

     We may invest 25% or more of assets in Municipal  Securities whose interest
is paid solely from  revenues of similar  projects.  For  example,  the fund may
invest more than 25% of its assets in Municipal  Securities  related to water or
sewer  systems.  This type of  concentration  exposes  the fund to the legal and
economic risks relating to those projects.

     We  will  rely on  legal  opinions  of  counsel  to  issuers  of  Municipal
Securities  as to the  tax-free  status of  investments  and will not do our own
analysis regarding tax-free status.

     The fund may purchase variable and floating rate instruments. Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                       12

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK / RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

================================================================================
                             IMPORTANT DEFINITIONS
MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund  during the  current  fiscal year ended
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.09% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.89%.  Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

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

================================================================================
                             IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate current income to provide you with liquidity and
to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest  exclusively  in short-term  U.S.  Treasury
bills, notes and other obligations  issued or guaranteed by the U.S.  Government
or its agencies or instrumentalities and related repurchase agreements.

     The fund seeks to maintain a net asset value of $1.00 per share.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
purchase securities if such securities or their issuers have (or such securities
are guaranteed or otherwise  supported by entities which have)  short-term  debt
ratings at the time of  purchase in the two highest  rating  categories  from at
least two national rating agencies,  or one such rating if the security is rated
by only one agency. The fund may also purchase unrated securities  determined by
us to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     SECURITIES LENDING

     The fund may lend some of its securities on a short-term  basis in order to
earn extra  income.  The fund will  receive  collateral  in cash or high quality
securities equal to the current value of the loaned securities. These loans will
be limited to 33 1/3% of the value of the fund's total assets.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government gives no assurances that it will provide  financial  support if it is
not obligated to do so by law. Default in these issuers could negatively  impact
the fund.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

     Securities  loans  involve  the  risk of a delay  in  receiving  additional
collateral if the value of the securities goes up while they are on loan.  There
is also the risk of delay in  recovering  the  loaned  securities  and of losing
rights to the  collateral if a borrower goes bankrupt.  Therefore,  the fund may
lose the opportunity to sell the securities at a desirable price.  Additionally,
in the event that a borrower of securities  would file for  bankruptcy or become
insolvent, disposition of the securities may be delayed pending court action.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.
================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.
================================================================================

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 ..................................       0.42%

     Distribution and service (12b-1) fees ..............       0.60%

     Other expenses .....................................       0.11%

     Total annual fund operating expenses 2 .............       1.13%
                                                                =====

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are  0.265% of average  daily net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.975%. Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                     1 YEAR        3 YEARS        5 YEARS        10 YEARS

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated  by dividing a fund's  total
assets, less its liabilities, by the number of shares outstanding.

     Each fund values its securities  using amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may purchase Bedford Shares through an account  maintained by
your brokerage firm (the "Account") and you may also purchase Shares directly by
mail or  wire.  The  minimum  initial  investment  is  $1,000,  and the  minimum
subsequent  investment is $100. The Company in its sole discretion may accept or
reject any order for purchases of Bedford Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
an Account with your broker through  procedures and requirements  established by
your  broker.  In such event,  beneficial  ownership  of Bedford  Shares will be
recorded by your broker and will be reflected in the Account statements provided
to you by your  broker.  Your  broker  may  impose  minimum  investment  Account
requirements.  Even if your broker does not impose a sales charge for  purchases
of Bedford Shares,  depending on the terms of your Account with your broker, the
broker  may  charge to your  Account  fees for  automatic  investment  and other
services provided to your Account.  Information concerning Account requirements,
services and charges  should be obtained  from your broker,  and you should read
this Prospectus in conjunction  with any information  received from your broker.
Shares are held in the street  name  account of your broker and if you desire to
transfer  such shares to the street name account of another  broker,  you should
contact your current broker.

     A broker  with whom you  maintain  an Account  may offer you the ability to
purchase  Bedford  Shares  under an  automatic  purchase  program  (a  "Purchase
Program")  established  by a  participating  broker.  If  you  participate  in a
Purchase Program,  then you will have your  "free-credit"  cash balances in your
Account automatically invested in Shares of the

                                       23

<PAGE>

     Bedford  Class  designated by you as the "Primary  Bedford  Class" for your
Purchase  Program.  The  frequency  of  investments  and the minimum  investment
requirement will be established by the broker and the Company. In addition,  the
broker may require a minimum amount of cash and/or securities to be deposited in
your Account to  participate  in its Purchase  Program.  The  description of the
particular  broker's  Purchase  Program  should  be read  for  details,  and any
inquiries concerning your Account under a Purchase Program should be directed to
your  broker.  As a  participant  in a  Purchase  Program,  you may  change  the
designation  of the Primary  Bedford  Class at any time by so  instructing  your
broker.

     If your broker makes  special  arrangements  under which orders for Bedford
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees that payment for such Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase  order is received by PFPC.  Otherwise,  if the broker has not
made such an arrangement,  pricing of shares will occur as described above under
"General".

     DIRECT PURCHASES.  You may also make direct  investments at any time in any
Bedford  Class you select  through  any broker  that has  entered  into a dealer
agreement with the Distributor (a "Dealer").  You may make an initial investment
in any of the  Bedford  Classes  by mail by  fully  completing  and  signing  an
application obtained from a Dealer (the "Application"), specifying the Portfolio
in which you wish to invest,  and mailing it,  together  with a check payable to
"The Bedford Family" to the Bedford Family, c/o PFPC, P.O. Box 8950, Wilmington,
Delaware  19899.  The check must  specify  the name of the  Portfolio  for which
shares are being  purchased.  An  Application  will be returned to you unless it
contains the name of the Dealer from whom you obtained it. Subsequent  purchases
may be made through a Dealer or by forwarding  payment to the Company's transfer
agent at the foregoing address.

     Provided that your  investment  is at least  $2,500,  you may also purchase
Shares in any of the Bedford  Classes by having your bank or Dealer wire Federal
Funds to the Company's  Custodian,  PFPC Trust Company.  Your bank or Dealer may
impose a charge for this  service.  The Company  does not  currently  charge for
effecting wire transfers but reserves the right to do so in the future. In order
to ensure prompt receipt of your Federal Funds wire, for an initial  investment,
it is important that you follow these steps:

       A. Telephone the Company's transfer agent, PFPC, toll-free (800) 533-7719
          and provide your name, address,  telephone number,  Social Security or
          Tax  Identification  Number,  the Bedford Class  selected,  the amount
          being wired,  and by which bank or Dealer.  PFPC will then provide you
          with an account number.  (If you have an existing account,  you should
          also notify PFPC prior to wiring funds.)

       B. Instruct  your bank or Dealer to wire the specified  amount,  together
          with your assigned  account  number,  to PFPC's account with PNC Bank.
          PNC Bank, N.A.,  Philadelphia,  PA
          ABA-0310-0005-3.
          FROM: (your name)
          ACCOUNT NUMBER:  (your account number with the Portfolio)
          FOR PURCHASE OF: (name of the Portfolio)
          AMOUNT: (amount to be invested)

       C. Fully  complete  and sign the  Application  and mail it to the address
          shown  thereon.  PFPC  will not  process  initial  purchases  until it
          receives a fully completed and signed Application.

     For subsequent investments, you should follow steps A and B above.

                                       24

     RETIREMENT  PLANS.  Bedford  Shares may be  purchased in  conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you beneficially own Bedford Shares
through an Account,  you may redeem Bedford Shares in your Account in accordance
with instructions and limitations  pertaining to your Account by contacting your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Your brokerage firm may also redeem each day a sufficient  number of Shares
of the Primary Bedford Class to cover debit balances  created by transactions in
your Account or instructions for cash disbursements.  Shares will be redeemed on
the same day that a  transaction  occurs that results in such a debit balance or
charge.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem any number of Shares by sending a written  request to The Bedford  Family
c/o PFPC, P.O. Box 8950, Wilmington, Delaware 19899. Redemption requests must be
signed by each  shareholder  in the same  manner as the Shares  are  registered.
Redemption  requests  for joint  accounts  require the  signature  of each joint
owner.  On  redemption  requests  of  $5,000  or more,  each  signature  must be
guaranteed.  A signature guarantee may be obtained from a domestic bank or trust
company,  broker,  dealer,  clearing  agency  or  savings  association  who  are
participants  in a  medallion  program  recognized  by the  Securities  Transfer
Association.  The three recognized  medallion  programs are Securities  Transfer
Agents Medallion Program (STAMP),  Stock Exchanges  Medallion Program (SEMP) and
New York Stock  Exchange,  Inc.  Medallion  Signature  Program (MSP).  Signature
guarantees that are not part of these programs will not be accepted.

     If you are a direct investor,  you may redeem your Shares without charge by
telephone if you have completed and returned an account  application  containing
the appropriate  telephone  election.  To add a telephone  option to an existing
account  that  previously  did not  provide  for this  option,  you must  file a
Telephone  Authorization  Form with PFPC. This form is available from PFPC. Once
this election has been made, you may simply contact PFPC by telephone to request
the redemption by calling (800) 533-7719.  Neither the Company, the Distributor,
the Portfolios, the Administrator nor any other Company agent will be liable for
any loss,  liability,  cost or expense for following the procedures below or for
following instructions communicated by telephone that they reasonably believe to
be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and name of the portfolio,  all of which must match the
Company's  records;  (3)  requiring  the  Company's  service  representative  to
complete  a  telephone  transaction  form,  listing  all  of  the  above  caller
identification

                                       25

<PAGE>

information; (4) requiring that redemption proceeds be sent only by check to the
account owners of record at the address of record, or by wire only to the owners
of record at the bank account of record; (5) sending a written  confirmation for
each  telephone  transaction  to the  owners of record at the  address of record
within  five  (5)  business  days of the  call;  and (6)  maintaining  tapes  of
telephone  transactions  for  six  months,  if  the  Company  elects  to  record
shareholder   telephone   transactions.   For   accounts   held  of   record  by
broker-dealers (other than the Distributor), financial institutions,  securities
dealers,   financial  planners  or  other  industry  professionals,   additional
documentation  or  information  regarding  the scope of  authority  is required.
Finally,  for  telephone  transactions  in  accounts  held  jointly,  additional
information regarding other account holders is required.  Telephone transactions
will not be permitted in connection  with IRA or other  retirement plan accounts
or by attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have designated in your  Application or Telephone
Authorization  Form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account  on the next day  that a wire  transfer  can be  effected.  The  minimum
redemption for proceeds sent by wire transfer is $2,500. There is no maximum for
proceeds sent by wire transfer.  The Company may modify this redemption  service
at any time or charge a service fee upon prior notice to shareholders,  although
no fee is currently contemplated.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $100; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves the right to redeem any account in a Bedford  Class  involuntarily,  on
thirty days'  notice,  if such  account  falls below $500 and during such 30-day
notice  period the amount  invested in such account is not increased to at least
$500.  Payment for Shares  redeemed may be postponed or the right of  redemption
suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interest of the remaining  shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable rules

                                       26

<PAGE>

of the SEC.  Investors  generally  will incur  brokerage  charges on the sale of
portfolio  securities  so  received  in payment of  redemptions.  The funds have
elected,  however,  to be  governed  by Rule 18f-1 under the 1940 Act, so that a
fund is  obligated  to redeem  its  Shares  solely  in cash up to the  lesser of
$250,000  or 1% of its net asset  value  during  any  90-day  period for any one
shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and  net  realized   capital  gains,  if  any,  of  each  fund  to  each  fund's
shareholders.  All  distributions  are reinvested in the form of additional full
and fractional Shares of the relevant Bedford Class unless a shareholder  elects
otherwise.  The net investment income (not including any net short-term  capital
gains)  earned by each fund will be  declared as a dividend on a daily basis and
paid monthly.  Dividends are payable to shareholders of record immediately prior
to the  determination  of net asset value made as of the close of trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions   from  the  Money  Market   Portfolio  and  the   Government
Obligations Money Market Portfolio will generally be taxable to shareholders. It
is expected that all, or substantially all, of these  distributions will consist
of  ordinary  income.  You will be subject to income tax on these  distributions
regardless of whether they are paid in cash or reinvested in additional  shares.
The one major exception to these tax principles is that  distributions on shares
held in an IRA (or other tax-qualified plan) will not be currently taxable.

     Distributions  from the Municipal  Money Market  Portfolio  will  generally
constitute  tax-exempt  income for shareholders for federal income tax purposes.
It is possible,  depending upon the Portfolios'  investments,  that a portion of
the  Portfolio's  distributions  could be taxable to  shareholders  as  ordinary
income or capital gains, but it is not expected that this will be the case.

     Interest on  indebtedness  incurred by a  shareholder  to purchase or carry
shares of the Municipal Money Market Portfolio  generally will not be deductible
for federal income tax purposes.

     You should note that a portion of the exempt-interest dividends paid by the
Municipal  Money Market  Portfolio may  constitute an item of tax preference for
purposes   of   determining   federal   alternative   minimum   tax   liability.
Exempt-interest  dividends  will also be  considered  along with other  adjusted
gross income in determining  whether any Social Security or railroad  retirement
payments received by you are subject to federal income taxes.

     Although distributions from the Municipal Money Market Portfolio are exempt
for federal income tax purposes,  they will generally  constitute taxable income
for state and local income tax purposes except that, subject to limitations that
vary  depending on the state,  distributions  from  interest  paid by a state or
municipal entity may be exempt from tax in that state.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Bedford  Shares of the funds are sold  without a sales load on a continuous
basis by Provident  Distributors,  Inc., whose principal  business address is at
Four Falls Corporate Center, West Conshohocken, PA 19428.

The Board of  Directors  of the Company  approved  and adopted the  Distribution
Agreement  and  separate  Plans  of   Distribution   for  each  of  the  Classes
(collectively,  the  "Plans")  pursuant to Rule 12b-1 under the 1940 Act.  Under
each of the Plans,  the  Distributor  is entitled to receive  from the  relevant
Bedford Class a distribution fee, which is accrued daily and paid monthly, of up
to .65% on an  annualized  basis of the average daily net assets of the relevant
Bedford Class.  The actual amount of such  compensation is agreed upon from time
to time by the  Company's  Board of  Directors  and the  Distributor.  Under the
Distribution  Agreement,  the Distributor has agreed to accept  compensation for
its services thereunder and under the Plans in the amount of .60% of the average
daily net assets of the relevant  Class on an annualized  basis in any year. The
Distributor may, in its discretion,  voluntarily  waive from time to time all or
any portion of its distribution fee.

Under the  Distribution  Agreement and the relevant  Plan, the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and services  provided to  shareholders  of any relevant
Class  serviced  by  such  financial  institutions.  the  Distributor  may  also
reimburse  broker/dealers  for other  expenses  incurred in the promotion of the
sale of Bedford Shares. The Distributor  and/or  broker/dealers pay for the cost
of  printing  (excluding  typesetting)  and  mailing  to  prospective  investors
prospectuses and other materials  relating to the Bedford Classes as well as for
related direct mail, advertising and promotional expenses.

     Each of the Plans obligates the Company, during the period it is in effect,
to accrue and pay to the  Distributor  on behalf of each  Bedford  Class the fee
agreed to under the  Distribution  Agreement.  Payments  under the Plans are not
based on expenses  actually  incurred by the  Distributor,  and the payments may
exceed distribution expenses actually incurred.  Because these fees are paid out
of the funds'  assets on an on-going  basis,  over time these fees will increase
the cost of your  investment  and may cost you more than  paying  other types of
sales charges.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES.

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)  U.S.  dollar-denominated  obligations issued or supported by the credit
         of U.S. or foreign banks or savings  institutions  with total assets of
         more than $1 billion (including obligations of foreign branches of such
         banks).

     2)  High  quality   commercial  paper  and  other  obligations   issued  or
         guaranteed  (or otherwise  supported) by U.S. and foreign  corporations
         and  other  issuers  rated (at the time of  purchase)  A-2 or higher by
         Standard  and Poor's,  Prime-2 or higher by  Moody's,  D-2 or higher by
         Duff & Phelps,  F-2 or  higher  by Fitch or TBW-2 or higher by  Thomson
         BankWatch,  as well as high quality corporate bonds rated AA (or Aa) or
         higher at the time of purchase by those rating  agencies.These  ratings
         must be provided by at least two rating agencies, or by the only rating
         agency providing a rating.

     3)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     4)  Asset-backed securities (including interests in pools of assets such as
         mortgages,   installment   purchase   obligations   and   credit   card
         receivables).

     5)  Securities  issued  or  guaranteed  by the  U.S.  Government  or by its
         agencies or authorities.

     6)  Dollar-denominated   securities   issued  or   guaranteed   by  foreign
         governments or their political subdivisions, agencies or authorities.

     7)  Securities issued or guaranteed by state or local governmental bodies.

     8)  Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                        6

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                        7

<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK / RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for

     Total annual fund operating expenses 2                     1.08%
                                                                =====

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.25% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.97%.  Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                    1 YEAR          3 YEARS         5 YEARS         10 YEARS

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

GENERAL  OBLIGATION BONDS: Bonds which are secured by the issuer's pledge of its
full faith, credit and taxing power for the payment of principal and interest.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

MUNICIPAL  LEASE  OBLIGATIONS:  These provide  participation  in municipal lease
agreements and installment  purchase contracts,  but are not part of the general
obligations of the municipality.

MUNICIPAL SECURITY: A short-term obligation issued by or on behalf of states and
possessions  of the  United  States,  their  political  subdivisions  and  their
agencies and authorities.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REVENUE  BONDS:  Bonds which are secured only by the revenues  from a particular
facility or class of  facilities,  such as a water or sewer system,  or from the
proceeds of a special excise tax or other revenue source.

TAX-EXEMPT COMMERCIAL PAPER:  Short-term Municipal Securities with maturities of
1 to 270 days.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.

INVESTMENT GOAL

     The fund seeks to generate current income exempt from federal income taxes,
to provide you with liquidity and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve  this goal,  we invest in a  diversified  portfolio of Municipal
Securities. Specifically, we may invest in:

     1)  Fixed and  variable  rate notes and similar debt  instruments  rated or
         issued by issuers  who have  ratings at the time of  purchase of MIG-2,
         VMIG-2  or  Prime-2  or  higher  by  Moody's,  SP-2 or A-2 or higher by
         Standard & Poor's,  D-2 or higher by Duff & Phelps, or F-2 or higher by
         Fitch (or  guaranteed  or  otherwise  supported  by entities  with such
         ratings).

     2)  Tax-exempt  commercial  paper and  similar  debt  instruments  rated or
         issued by issuers  who have  ratings at the time of purchase of Prime-2
         or higher by Moody's, A-2 or higher by Standard & Poor's, D-2 or higher
         by Duff & Phelps, or F-2 or higher by Fitch (or guaranteed or otherwise
         supported by entities with such ratings).

     3)  Municipal bonds rated or issued by issuers who have ratings at the time
         of  purchase  of Aa or higher by Moody's or AA or higher by  Standard &
         Poor's, Duff & Phelps or Fitch (or guaranteed or otherwise supported by
         entities with such ratings).

     4)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     5)  Municipal  bonds and notes whose  principal  and interest  payments are
         guaranteed by the U.S. Government or one of its agencies or authorities
         or which otherwise depend on the credit of the United States.

     The fund seeks to maintain a net asset value of $1.00 per share.

     We normally  invest at least 80% of its net assets in Municipal  Securities
and other  instruments  whose  interest  is exempt  from  federal  income tax or
subject to the Federal Alternative Minimum Tax.

     The fund may hold  uninvested  cash  reserves  during  temporary  defensive
periods or, if in our opinion suitable  Municipal  Securities are not available.
The fund may hold all of its assets in uninvested cash reserves during temporary
defensive periods. Uninvested cash will not earn income.

     We  intend  to have no more  than  25% of its  total  assets  in  Municipal
Securities of issuers located in the same state.

                                       11

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain variable and floating rate  instruments)
will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Municipal  Securities  include revenue bonds,  general obligation bonds and
municipal lease obligations. Revenue bonds include private activity bonds, which
are not payable  from the general  revenues  of the  issuer.  Consequently,  the
credit  quality of private  activity  bonds is usually  directly  related to the
credit  standing of the corporate user of the facility  involved.  To the extent
that the fund's assets are invested in private  activity bonds, the fund will be
subject to the particular  risks  presented by the laws and economic  conditions
relating to such projects and bonds to a greater  extent than if its assets were
not so invested.  Moral  obligation bonds are normally issued by special purpose
public authorities. If the issuer of moral obligation bonds is unable to pay its
debts from current  revenues,  it may draw on a reserve fund the  restoration of
which is a moral but not a legal  obligation of the state or municipality  which
created  the  issuer.  Risk  exists  that a  municipality  will not honor  moral
obligation  bonds.  Municipal lease obligations are not guaranteed by the issuer
and are generally less liquid than other securities.

     There may be less  information  available  on the  financial  condition  of
issuers of Municipal  Securities  than for public  corporations.  The market for
municipal  bonds may be less liquid than for taxable  bonds.  This means that it
may be harder to buy and sell Municipal Securities, especially on short notice.

     The fund may invest in bonds whose  interest  may be subject to the Federal
Alternative  Minimum Tax. Interest received on these bonds by a taxpayer subject
to the Federal Alternative Minimum Tax is taxable.

     We may invest 25% or more of assets in Municipal  Securities whose interest
is paid solely from  revenues of similar  projects.  For  example,  the fund may
invest more than 25% of its assets in Municipal  Securities  related to water or
sewer  systems.  This type of  concentration  exposes  the fund to the legal and
economic risks relating to those projects.

     We  will  rely on  legal  opinions  of  counsel  to  issuers  of  Municipal
Securities  as to the  tax-free  status of  investments  and will not do our own
analysis regarding tax-free status.

     The fund may purchase variable and floating rate instruments. Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                       12

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK / RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

                             IMPORTANT DEFINITIONS
MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund  during the  current  fiscal year ended
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.09% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.89%.  Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

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

================================================================================
                             IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate current income to provide you with liquidity and
to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest  exclusively  in short-term  U.S.  Treasury
bills, notes and other obligations  issued or guaranteed by the U.S.  Government
or its agencies or instrumentalities and related repurchase agreements.

     The fund seeks to maintain a net asset value of $1.00 per share.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
purchase securities if such securities or their issuers have (or such securities
are guaranteed or otherwise  supported by entities which have)  short-term  debt
ratings at the time of  purchase in the two highest  rating  categories  from at
least two national rating agencies,  or one such rating if the security is rated
by only one agency. The fund may also purchase unrated securities  determined by
us to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     SECURITIES LENDING

     The fund may lend some of its securities on a short-term  basis in order to
earn extra  income.  The fund will  receive  collateral  in cash or high quality
securities equal to the current value of the loaned securities. These loans will
be limited to 33 1/3% of the value of the fund's total assets.

                                       16

<PAGE>

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government gives no assurances that it will provide  financial  support if it is
not obligated to do so by law. Default in these issuers could negatively  impact
the fund.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

     Securities  loans  involve  the  risk of a delay  in  receiving  additional
collateral if the value of the securities goes up while they are on loan.  There
is also the risk of delay in  recovering  the  loaned  securities  and of losing
rights to the  collateral if a borrower goes bankrupt.  Therefore,  the fund may
lose the opportunity to sell the securities at a desirable price.  Additionally,
in the event that a borrower of securities  would file for  bankruptcy or become
insolvent, disposition of the securities may be delayed pending court action.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.
================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.
================================================================================

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 ..................................       0.42%

     Distribution and service (12b-1) fees ..............       0.60%

     Other expenses .....................................       0.11%
                                                                -----
     Total annual fund operating expenses 2 .............       1.13%
                                                                =====

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are  0.265% of average  daily net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.975%. Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                     1 YEAR        3 YEARS        5 YEARS        10 YEARS

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated  by dividing a fund's  total
assets, less its liabilities, by the number of shares outstanding.

     Each fund values its securities  using amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may purchase Bedford Shares through an account  maintained by
your brokerage firm (the "Account") and you may also purchase Shares directly by
mail or  wire.  The  minimum  initial  investment  is  $1,000,  and the  minimum
subsequent  investment is $100. The Company in its sole discretion may accept or
reject any order for purchases of Bedford Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
an Account with your broker through  procedures and requirements  established by
your  broker.  In such event,  beneficial  ownership  of Bedford  Shares will be
recorded by your broker and will be reflected in the Account statements provided
to you by your  broker.  Your  broker  may  impose  minimum  investment  Account
requirements.  Even if your broker does not impose a sales charge for  purchases
of Bedford Shares,  depending on the terms of your Account with your broker, the
broker  may  charge to your  Account  fees for  automatic  investment  and other
services provided to your Account.  Information concerning Account requirements,
services and charges  should be obtained  from your broker,  and you should read
this Prospectus in conjunction  with any information  received from your broker.
Shares are held in the street  name  account of your broker and if you desire to
transfer  such shares to the street name account of another  broker,  you should
contact your current broker.

     A broker  with whom you  maintain  an Account  may offer you the ability to
purchase  Bedford  Shares  under an  automatic  purchase  program  (a  "Purchase
Program")  established  by a  participating  broker.  If  you  participate  in a
Purchase Program,  then you will have your  "free-credit"  cash balances in your
Account automatically invested in Shares of the

                                       23

<PAGE>

     Bedford  Class  designated by you as the "Primary  Bedford  Class" for your
Purchase  Program.  The  frequency  of  investments  and the minimum  investment
requirement will be established by the broker and the Company. In addition,  the
broker may require a minimum amount of cash and/or securities to be deposited in
your Account to  participate  in its Purchase  Program.  The  description of the
particular  broker's  Purchase  Program  should  be read  for  details,  and any
inquiries concerning your Account under a Purchase Program should be directed to
your  broker.  As a  participant  in a  Purchase  Program,  you may  change  the
designation  of the Primary  Bedford  Class at any time by so  instructing  your
broker.

     If your broker makes  special  arrangements  under which orders for Bedford
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees that payment for such Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase  order is received by PFPC.  Otherwise,  if the broker has not
made such an arrangement,  pricing of shares will occur as described above under
"General".

     DIRECT PURCHASES.  You may also make direct  investments at any time in any
Bedford  Class you select  through  any broker  that has  entered  into a dealer
agreement with the Distributor (a "Dealer").  You may make an initial investment
in any of the  Bedford  Classes  by mail by  fully  completing  and  signing  an
application obtained from a Dealer (the "Application"), specifying the Portfolio
in which you wish to invest,  and mailing it,  together  with a check payable to
"The Bedford Family" to the Bedford Family, c/o PFPC, P.O. Box 8950, Wilmington,
Delaware  19899.  The check must  specify  the name of the  Portfolio  for which
shares are being  purchased.  An  Application  will be returned to you unless it
contains the name of the Dealer from whom you obtained it. Subsequent  purchases
may be made through a Dealer or by forwarding  payment to the Company's transfer
agent at the foregoing address.

     Provided that your  investment  is at least  $2,500,  you may also purchase
Shares in any of the Bedford  Classes by having your bank or Dealer wire Federal
Funds to the Company's  Custodian,  PFPC Trust Company.  Your bank or Dealer may
impose a charge for this  service.  The Company  does not  currently  charge for
effecting wire transfers but reserves the right to do so in the future. In order
to ensure prompt receipt of your Federal Funds wire, for an initial  investment,
it is important that you follow these steps:

       A. Telephone the Company's transfer agent, PFPC, toll-free (800) 533-7719
          and provide your name, address,  telephone number,  Social Security or
          Tax  Identification  Number,  the Bedford Class  selected,  the amount
          being wired,  and by which bank or Dealer.  PFPC will then provide you
          with an account number.  (If you have an existing account,  you should
          also notify PFPC prior to wiring funds.)

       B. Instruct  your bank or Dealer to wire the specified  amount,  together
          with your assigned  account  number,  to PFPC's account with PNC Bank.
          PNC Bank, N.A.,  Philadelphia,  PA
          ABA-0310-0005-3.
          FROM: (your name)
          ACCOUNT NUMBER:  (your account number with the Portfolio)
          FOR PURCHASE OF: (name of the Portfolio)
          AMOUNT: (amount to be invested)

       C. Fully  complete  and sign the  Application  and mail it to the address
          shown  thereon.  PFPC  will not  process  initial  purchases  until it
          receives a fully completed and signed Application.

     For subsequent investments, you should follow steps A and B above.

                                       24

     RETIREMENT  PLANS.  Bedford  Shares may be  purchased in  conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you beneficially own Bedford Shares
through an Account,  you may redeem Bedford Shares in your Account in accordance
with instructions and limitations  pertaining to your Account by contacting your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Your brokerage firm may also redeem each day a sufficient  number of Shares
of the Primary Bedford Class to cover debit balances  created by transactions in
your Account or instructions for cash disbursements.  Shares will be redeemed on
the same day that a  transaction  occurs that results in such a debit balance or
charge.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem any number of Shares by sending a written  request to The Bedford  Family
c/o PFPC, P.O. Box 8950, Wilmington, Delaware 19899. Redemption requests must be
signed by each  shareholder  in the same  manner as the Shares  are  registered.
Redemption  requests  for joint  accounts  require the  signature  of each joint
owner.  On  redemption  requests  of  $5,000  or more,  each  signature  must be
guaranteed.  A signature guarantee may be obtained from a domestic bank or trust
company,  broker,  dealer,  clearing  agency  or  savings  association  who  are
participants  in a  medallion  program  recognized  by the  Securities  Transfer
Association.  The three recognized  medallion  programs are Securities  Transfer
Agents Medallion Program (STAMP),  Stock Exchanges  Medallion Program (SEMP) and
New York Stock  Exchange,  Inc.  Medallion  Signature  Program (MSP).  Signature
guarantees that are not part of these programs will not be accepted.

     If you are a direct investor,  you may redeem your Shares without charge by
telephone if you have completed and returned an account  application  containing
the appropriate  telephone  election.  To add a telephone  option to an existing
account  that  previously  did not  provide  for this  option,  you must  file a
Telephone  Authorization  Form with PFPC. This form is available from PFPC. Once
this election has been made, you may simply contact PFPC by telephone to request
the redemption by calling (800) 533-7719.  Neither the Company, the Distributor,
the Portfolios, the Administrator nor any other Company agent will be liable for
any loss,  liability,  cost or expense for following the procedures below or for
following instructions communicated by telephone that they reasonably believe to
be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and name of the portfolio,  all of which must match the
Company's  records;  (3)  requiring  the  Company's  service  representative  to
complete  a  telephone  transaction  form,  listing  all  of  the  above  caller
identification

                                       25

<PAGE>

information; (4) requiring that redemption proceeds be sent only by check to the
account owners of record at the address of record, or by wire only to the owners
of record at the bank account of record; (5) sending a written  confirmation for
each  telephone  transaction  to the  owners of record at the  address of record
within  five  (5)  business  days of the  call;  and (6)  maintaining  tapes  of
telephone  transactions  for  six  months,  if  the  Company  elects  to  record
shareholder   telephone   transactions.   For   accounts   held  of   record  by
broker-dealers (other than the Distributor), financial institutions,  securities
dealers,   financial  planners  or  other  industry  professionals,   additional
documentation  or  information  regarding  the scope of  authority  is required.
Finally,  for  telephone  transactions  in  accounts  held  jointly,  additional
information regarding other account holders is required.  Telephone transactions
will not be permitted in connection  with IRA or other  retirement plan accounts
or by attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have designated in your  Application or Telephone
Authorization  Form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account  on the next day  that a wire  transfer  can be  effected.  The  minimum
redemption for proceeds sent by wire transfer is $2,500. There is no maximum for
proceeds sent by wire transfer.  The Company may modify this redemption  service
at any time or charge a service fee upon prior notice to shareholders,  although
no fee is currently contemplated.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $100; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves the right to redeem any account in a Bedford  Class  involuntarily,  on
thirty days'  notice,  if such  account  falls below $500 and during such 30-day
notice  period the amount  invested in such account is not increased to at least
$500.  Payment for Shares  redeemed may be postponed or the right of  redemption
suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interest of the remaining  shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable rules

                                       26

<PAGE>

of the SEC.  Investors  generally  will incur  brokerage  charges on the sale of
portfolio  securities  so  received  in payment of  redemptions.  The funds have
elected,  however,  to be  governed  by Rule 18f-1 under the 1940 Act, so that a
fund is  obligated  to redeem  its  Shares  solely  in cash up to the  lesser of
$250,000  or 1% of its net asset  value  during  any  90-day  period for any one
shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and  net  realized   capital  gains,  if  any,  of  each  fund  to  each  fund's
shareholders.  All  distributions  are reinvested in the form of additional full
and fractional Shares of the relevant Bedford Class unless a shareholder  elects
otherwise.  The net investment income (not including any net short-term  capital
gains)  earned by each fund will be  declared as a dividend on a daily basis and
paid monthly.  Dividends are payable to shareholders of record immediately prior
to the  determination  of net asset value made as of the close of trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions   from  the  Money  Market   Portfolio  and  the   Government
Obligations Money Market Portfolio will generally be taxable to shareholders. It
is expected that all, or substantially all, of these  distributions will consist
of  ordinary  income.  You will be subject to income tax on these  distributions
regardless of whether they are paid in cash or reinvested in additional  shares.
The one major exception to these tax principles is that  distributions on shares
held in an IRA (or other tax-qualified plan) will not be currently taxable.

     Distributions  from the Municipal  Money Market  Portfolio  will  generally
constitute  tax-exempt  income for shareholders for federal income tax purposes.
It is possible,  depending upon the Portfolios'  investments,  that a portion of
the  Portfolio's  distributions  could be taxable to  shareholders  as  ordinary
income or capital gains, but it is not expected that this will be the case.

     Interest on  indebtedness  incurred by a  shareholder  to purchase or carry
shares of the Municipal Money Market Portfolio  generally will not be deductible
for federal income tax purposes.

     You should note that a portion of the exempt-interest dividends paid by the
Municipal  Money Market  Portfolio may  constitute an item of tax preference for
purposes   of   determining   federal   alternative   minimum   tax   liability.
Exempt-interest  dividends  will also be  considered  along with other  adjusted
gross income in determining  whether any Social Security or railroad  retirement
payments received by you are subject to federal income taxes.

     Although distributions from the Municipal Money Market Portfolio are exempt
for federal income tax purposes,  they will generally  constitute taxable income
for state and local income tax purposes except that, subject to limitations that
vary  depending on the state,  distributions  from  interest  paid by a state or
municipal entity may be exempt from tax in that state.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Bedford  Shares of the funds are sold  without a sales load on a continuous
basis by Provident  Distributors,  Inc., whose principal  business address is at
Four Falls Corporate Center, West Conshohocken, PA 19428.

The Board of  Directors  of the Company  approved  and adopted the  Distribution
Agreement  and  separate  Plans  of   Distribution   for  each  of  the  Classes
(collectively,  the  "Plans")  pursuant to Rule 12b-1 under the 1940 Act.  Under
each of the Plans,  the  Distributor  is entitled to receive  from the  relevant
Bedford Class a distribution fee, which is accrued daily and paid monthly, of up
to .65% on an  annualized  basis of the average daily net assets of the relevant
Bedford Class.  The actual amount of such  compensation is agreed upon from time
to time by the  Company's  Board of  Directors  and the  Distributor.  Under the
Distribution  Agreement,  the Distributor has agreed to accept  compensation for
its services thereunder and under the Plans in the amount of .60% of the average
daily net assets of the relevant  Class on an annualized  basis in any year. The
Distributor may, in its discretion,  voluntarily  waive from time to time all or
any portion of its distribution fee.

Under the  Distribution  Agreement and the relevant  Plan, the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and services  provided to  shareholders  of any relevant
Class  serviced  by  such  financial  institutions.  the  Distributor  may  also
reimburse  broker/dealers  for other  expenses  incurred in the promotion of the
sale of Bedford Shares. The Distributor  and/or  broker/dealers pay for the cost
of  printing  (excluding  typesetting)  and  mailing  to  prospective  investors
prospectuses and other materials  relating to the Bedford Classes as well as for
related direct mail, advertising and promotional expenses.

     Each of the Plans obligates the Company, during the period it is in effect,
to accrue and pay to the  Distributor  on behalf of each  Bedford  Class the fee
agreed to under the  Distribution  Agreement.  Payments  under the Plans are not
based on expenses  actually  incurred by the  Distributor,  and the payments may
exceed distribution expenses actually incurred.  Because these fees are paid out
of the funds'  assets on an on-going  basis,  over time these fees will increase
the cost of your  investment  and may cost you more than  paying  other types of
sales charges.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES.

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)  U.S.  dollar-denominated  obligations issued or supported by the credit
         of U.S. or foreign banks or savings  institutions  with total assets of
         more than $1 billion (including obligations of foreign branches of such
         banks).

     2)  High  quality   commercial  paper  and  other  obligations   issued  or
         guaranteed  (or otherwise  supported) by U.S. and foreign  corporations
         and  other  issuers  rated (at the time of  purchase)  A-2 or higher by
         Standard  and Poor's,  Prime-2 or higher by  Moody's,  D-2 or higher by
         Duff & Phelps,  F-2 or  higher  by Fitch or TBW-2 or higher by  Thomson
         BankWatch,  as well as high quality corporate bonds rated AA (or Aa) or
         higher at the time of purchase by those rating  agencies.These  ratings
         must be provided by at least two rating agencies, or by the only rating
         agency providing a rating.

     3)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     4)  Asset-backed securities (including interests in pools of assets such as
         mortgages,   installment   purchase   obligations   and   credit   card
         receivables).

     5)  Securities  issued  or  guaranteed  by the  U.S.  Government  or by its
         agencies or authorities.

     6)  Dollar-denominated   securities   issued  or   guaranteed   by  foreign
         governments or their political subdivisions, agencies or authorities.

     7)  Securities issued or guaranteed by state or local governmental bodies.

     8)  Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                        6

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                        7

<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK / RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.25% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.97%.  Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

         by Duff & Phelps, or F-2 or higher by Fitch (or guaranteed or otherwise
         supported by entities with such ratings).

     3)  Municipal bonds rated or issued by issuers who have ratings at the time
         of  purchase  of Aa or higher by Moody's or AA or higher by  Standard &
         Poor's, Duff & Phelps or Fitch (or guaranteed or otherwise supported by
         entities with such ratings).

     4)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     5)  Municipal  bonds and notes whose  principal  and interest  payments are
         guaranteed by the U.S. Government or one of its agencies or authorities
         or which otherwise depend on the credit of the United States.

     The fund seeks to maintain a net asset value of $1.00 per share.

     We normally  invest at least 80% of its net assets in Municipal  Securities
and other  instruments  whose  interest  is exempt  from  federal  income tax or
subject to the Federal Alternative Minimum Tax.

     The fund may hold  uninvested  cash  reserves  during  temporary  defensive
periods or, if in our opinion suitable  Municipal  Securities are not available.
The fund may hold all of its assets in uninvested cash reserves during temporary
defensive periods. Uninvested cash will not earn income.

     We  intend  to have no more  than  25% of its  total  assets  in  Municipal
Securities of issuers located in the same state.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain variable and floating rate  instruments)
will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Municipal  Securities  include revenue bonds,  general obligation bonds and
municipal lease obligations. Revenue bonds include private activity bonds, which
are not payable  from the general  revenues  of the  issuer.  Consequently,  the
credit  quality of private  activity  bonds is usually  directly  related to the
credit  standing of the corporate user of the facility  involved.  To the extent
that the fund's assets are invested in private  activity bonds, the fund will be
subject to the particular  risks  presented by the laws and economic  conditions
relating to such projects and bonds to a greater  extent than if its assets were
not so invested.  Moral  obligation bonds are normally issued by special purpose
public authorities. If the issuer of moral obligation bonds is unable to pay its
debts from current  revenues,  it may draw on a reserve fund the  restoration of
which is a moral but not a legal  obligation of the state or municipality  which
created  the  issuer.  Risk  exists  that a  municipality  will not honor  moral
obligation  bonds.  Municipal lease obligations are not guaranteed by the issuer
and are generally less liquid than other securities.

     There may be less  information  available  on the  financial  condition  of
issuers of Municipal  Securities  than for public  corporations.  The market for
municipal  bonds may be less liquid than for taxable  bonds.  This means that it
may be harder to buy and sell Municipal Securities, especially on short notice.

     The fund may invest in bonds whose  interest  may be subject to the Federal
Alternative  Minimum Tax. Interest received on these bonds by a taxpayer subject
to the Federal Alternative Minimum Tax is taxable.

     We may invest 25% or more of assets in Municipal  Securities whose interest
is paid solely from  revenues of similar  projects.  For  example,  the fund may
invest more than 25% of its assets in Municipal  Securities  related to water or
sewer  systems.  This type of  concentration  exposes  the fund to the legal and
economic risks relating to those projects.

     We  will  rely on  legal  opinions  of  counsel  to  issuers  of  Municipal
Securities  as to the  tax-free  status of  investments  and will not do our own
analysis regarding tax-free status.

     The fund may purchase variable and floating rate instruments. Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

                             IMPORTANT DEFINITIONS
MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund  during the  current  fiscal year ended
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.09% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.89%.  Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

================================================================================
                             IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate current income to provide you with liquidity and
to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest  exclusively  in short-term  U.S.  Treasury
bills, notes and other obligations  issued or guaranteed by the U.S.  Government
or its agencies or instrumentalities and related repurchase agreements.

     The fund seeks to maintain a net asset value of $1.00 per share.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
purchase securities if such securities or their issuers have (or such securities
are guaranteed or otherwise  supported by entities which have)  short-term  debt
ratings at the time of  purchase in the two highest  rating  categories  from at
least two national rating agencies,  or one such rating if the security is rated
by only one agency. The fund may also purchase unrated securities  determined by
us to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     SECURITIES LENDING

     The fund may lend some of its securities on a short-term  basis in order to
earn extra  income.  The fund will  receive  collateral  in cash or high quality
securities equal to the current value of the loaned securities. These loans will
be limited to 33 1/3% of the value of the fund's total assets.

                                       16

<PAGE>

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government gives no assurances that it will provide  financial  support if it is
not obligated to do so by law. Default in these issuers could negatively  impact
the fund.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

     Securities  loans  involve  the  risk of a delay  in  receiving  additional
collateral if the value of the securities goes up while they are on loan.  There
is also the risk of delay in  recovering  the  loaned  securities  and of losing
rights to the  collateral if a borrower goes bankrupt.  Therefore,  the fund may
lose the opportunity to sell the securities at a desirable price.  Additionally,
in the event that a borrower of securities  would file for  bankruptcy or become
insolvent, disposition of the securities may be delayed pending court action.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.
================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.
================================================================================

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 ..................................       0.42%

     Distribution and service (12b-1) fees ..............       0.60%

     Other expenses .....................................       0.11%
                                                                -----
     Total annual fund operating expenses 2 .............       1.13%
                                                                =====

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are  0.265% of average  daily net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  As a result of the fee  waiver  set  forth in note 1, the total  annual
         fund operating  expenses which are estimated to be incurred  during the
         current fiscal year are 0.975%. Although this fee waiver is expected to
         remain in effect for the current  fiscal year,  it is voluntary and may
         be terminated at any time at the option of BIMC.

EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                     1 YEAR        3 YEARS        5 YEARS        10 YEARS

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated  by dividing a fund's  total
assets, less its liabilities, by the number of shares outstanding.

     Each fund values its securities  using amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may purchase Bedford Shares through an account  maintained by
your brokerage firm (the "Account") and you may also purchase Shares directly by
mail or  wire.  The  minimum  initial  investment  is  $1,000,  and the  minimum
subsequent  investment is $100. The Company in its sole discretion may accept or
reject any order for purchases of Bedford Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
an Account with your broker through  procedures and requirements  established by
your  broker.  In such event,  beneficial  ownership  of Bedford  Shares will be
recorded by your broker and will be reflected in the Account statements provided
to you by your  broker.  Your  broker  may  impose  minimum  investment  Account
requirements.  Even if your broker does not impose a sales charge for  purchases
of Bedford Shares,  depending on the terms of your Account with your broker, the
broker  may  charge to your  Account  fees for  automatic  investment  and other
services provided to your Account.  Information concerning Account requirements,
services and charges  should be obtained  from your broker,  and you should read
this Prospectus in conjunction  with any information  received from your broker.
Shares are held in the street  name  account of your broker and if you desire to
transfer  such shares to the street name account of another  broker,  you should
contact your current broker.

     A broker  with whom you  maintain  an Account  may offer you the ability to
purchase  Bedford  Shares  under an  automatic  purchase  program  (a  "Purchase
Program")  established  by a  participating  broker.  If  you  participate  in a
Purchase Program,  then you will have your  "free-credit"  cash balances in your
Account automatically invested in Shares of the

                                       23

<PAGE>

     Bedford  Class  designated by you as the "Primary  Bedford  Class" for your
Purchase  Program.  The  frequency  of  investments  and the minimum  investment
requirement will be established by the broker and the Company. In addition,  the
broker may require a minimum amount of cash and/or securities to be deposited in
your Account to  participate  in its Purchase  Program.  The  description of the
particular  broker's  Purchase  Program  should  be read  for  details,  and any
inquiries concerning your Account under a Purchase Program should be directed to
your  broker.  As a  participant  in a  Purchase  Program,  you may  change  the
designation  of the Primary  Bedford  Class at any time by so  instructing  your
broker.

     If your broker makes  special  arrangements  under which orders for Bedford
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees that payment for such Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase  order is received by PFPC.  Otherwise,  if the broker has not
made such an arrangement,  pricing of shares will occur as described above under
"General".

     DIRECT PURCHASES.  You may also make direct  investments at any time in any
Bedford  Class you select  through  any broker  that has  entered  into a dealer
agreement with the Distributor (a "Dealer").  You may make an initial investment
in any of the  Bedford  Classes  by mail by  fully  completing  and  signing  an
application obtained from a Dealer (the "Application"), specifying the Portfolio
in which you wish to invest,  and mailing it,  together  with a check payable to
"The Bedford Family" to the Bedford Family, c/o PFPC, P.O. Box 8950, Wilmington,
Delaware  19899.  The check must  specify  the name of the  Portfolio  for which
shares are being  purchased.  An  Application  will be returned to you unless it
contains the name of the Dealer from whom you obtained it. Subsequent  purchases
may be made through a Dealer or by forwarding  payment to the Company's transfer
agent at the foregoing address.

     Provided that your  investment  is at least  $2,500,  you may also purchase
Shares in any of the Bedford  Classes by having your bank or Dealer wire Federal
Funds to the Company's  Custodian,  PFPC Trust Company.  Your bank or Dealer may
impose a charge for this  service.  The Company  does not  currently  charge for
effecting wire transfers but reserves the right to do so in the future. In order
to ensure prompt receipt of your Federal Funds wire, for an initial  investment,
it is important that you follow these steps:

       A. Telephone the Company's transfer agent, PFPC, toll-free (800) 533-7719
          and provide your name, address,  telephone number,  Social Security or
          Tax  Identification  Number,  the Bedford Class  selected,  the amount
          being wired,  and by which bank or Dealer.  PFPC will then provide you
          with an account number.  (If you have an existing account,  you should
          also notify PFPC prior to wiring funds.)

       B. Instruct  your bank or Dealer to wire the specified  amount,  together
          with your assigned  account  number,  to PFPC's account with PNC Bank.

     RETIREMENT  PLANS.  Bedford  Shares may be  purchased in  conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you beneficially own Bedford Shares
through an Account,  you may redeem Bedford Shares in your Account in accordance
with instructions and limitations  pertaining to your Account by contacting your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Your brokerage firm may also redeem each day a sufficient  number of Shares
of the Primary Bedford Class to cover debit balances  created by transactions in
your Account or instructions for cash disbursements.  Shares will be redeemed on
the same day that a  transaction  occurs that results in such a debit balance or
charge.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem any number of Shares by sending a written  request to The Bedford  Family
c/o PFPC, P.O. Box 8950, Wilmington, Delaware 19899. Redemption requests must be
signed by each  shareholder  in the same  manner as the Shares  are  registered.
Redemption  requests  for joint  accounts  require the  signature  of each joint
owner.  On  redemption  requests  of  $5,000  or more,  each  signature  must be
guaranteed.  A signature guarantee may be obtained from a domestic bank or trust
company,  broker,  dealer,  clearing  agency  or  savings  association  who  are
participants  in a  medallion  program  recognized  by the  Securities  Transfer
Association.  The three recognized  medallion  programs are Securities  Transfer
Agents Medallion Program (STAMP),  Stock Exchanges  Medallion Program (SEMP) and
New York Stock  Exchange,  Inc.  Medallion  Signature  Program (MSP).  Signature
guarantees that are not part of these programs will not be accepted.

     If you are a direct investor,  you may redeem your Shares without charge by
telephone if you have completed and returned an account  application  containing
the appropriate  telephone  election.  To add a telephone  option to an existing
account  that  previously  did not  provide  for this  option,  you must  file a
Telephone  Authorization  Form with PFPC. This form is available from PFPC. Once
this election has been made, you may simply contact PFPC by telephone to request
the redemption by calling (800) 533-7719.  Neither the Company, the Distributor,
the Portfolios, the Administrator nor any other Company agent will be liable for
any loss,  liability,  cost or expense for following the procedures below or for
following instructions communicated by telephone that they reasonably believe to
be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and name of the portfolio,  all of which must match the
Company's  records;  (3)  requiring  the  Company's  service  representative  to
complete  a  telephone  transaction  form,  listing  all  of  the  above  caller
identification

                                       25

<PAGE>

information; (4) requiring that redemption proceeds be sent only by check to the
account owners of record at the address of record, or by wire only to the owners
of record at the bank account of record; (5) sending a written  confirmation for
each  telephone  transaction  to the  owners of record at the  address of record
within  five  (5)  business  days of the  call;  and (6)  maintaining  tapes  of
telephone  transactions  for  six  months,  if  the  Company  elects  to  record
shareholder   telephone   transactions.   For   accounts   held  of   record  by
broker-dealers (other than the Distributor), financial institutions,  securities
dealers,   financial  planners  or  other  industry  professionals,   additional
documentation  or  information  regarding  the scope of  authority  is required.
Finally,  for  telephone  transactions  in  accounts  held  jointly,  additional
information regarding other account holders is required.  Telephone transactions
will not be permitted in connection  with IRA or other  retirement plan accounts
or by attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have designated in your  Application or Telephone
Authorization  Form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account  on the next day  that a wire  transfer  can be  effected.  The  minimum
redemption for proceeds sent by wire transfer is $2,500. There is no maximum for
proceeds sent by wire transfer.  The Company may modify this redemption  service
at any time or charge a service fee upon prior notice to shareholders,  although
no fee is currently contemplated.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $100; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves the right to redeem any account in a Bedford  Class  involuntarily,  on
thirty days'  notice,  if such  account  falls below $500 and during such 30-day
notice  period the amount  invested in such account is not increased to at least
$500.  Payment for Shares  redeemed may be postponed or the right of  redemption
suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interest of the remaining  shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable rules

                                       26

<PAGE>

of the SEC.  Investors  generally  will incur  brokerage  charges on the sale of
portfolio  securities  so  received  in payment of  redemptions.  The funds have
elected,  however,  to be  governed  by Rule 18f-1 under the 1940 Act, so that a
fund is  obligated  to redeem  its  Shares  solely  in cash up to the  lesser of
$250,000  or 1% of its net asset  value  during  any  90-day  period for any one
shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and  net  realized   capital  gains,  if  any,  of  each  fund  to  each  fund's
shareholders.  All  distributions  are reinvested in the form of additional full
and fractional Shares of the relevant Bedford Class unless a shareholder  elects
otherwise.  The net investment income (not including any net short-term  capital
gains)  earned by each fund will be  declared as a dividend on a daily basis and
paid monthly.  Dividends are payable to shareholders of record immediately prior
to the  determination  of net asset value made as of the close of trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions   from  the  Money  Market   Portfolio  and  the   Government
Obligations Money Market Portfolio will generally be taxable to shareholders. It
is expected that all, or substantially all, of these  distributions will consist
of  ordinary  income.  You will be subject to income tax on these  distributions
regardless of whether they are paid in cash or reinvested in additional  shares.
The one major exception to these tax principles is that  distributions on shares
held in an IRA (or other tax-qualified plan) will not be currently taxable.

     Distributions  from the Municipal  Money Market  Portfolio  will  generally
constitute  tax-exempt  income for shareholders for federal income tax purposes.
It is possible,  depending upon the Portfolios'  investments,  that a portion of
the  Portfolio's  distributions  could be taxable to  shareholders  as  ordinary
income or capital gains, but it is not expected that this will be the case.

     Interest on  indebtedness  incurred by a  shareholder  to purchase or carry
shares of the Municipal Money Market Portfolio  generally will not be deductible
for federal income tax purposes.

     You should note that a portion of the exempt-interest dividends paid by the
Municipal  Money Market  Portfolio may  constitute an item of tax preference for
purposes   of   determining   federal   alternative   minimum   tax   liability.
Exempt-interest  dividends  will also be  considered  along with other  adjusted
gross income in determining  whether any Social Security or railroad  retirement
payments received by you are subject to federal income taxes.

     Although distributions from the Municipal Money Market Portfolio are exempt
for federal income tax purposes,  they will generally  constitute taxable income
for state and local income tax purposes except that, subject to limitations that
vary  depending on the state,  distributions  from  interest  paid by a state or
municipal entity may be exempt from tax in that state.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Bedford  Shares of the funds are sold  without a sales load on a continuous
basis by Provident  Distributors,  Inc., whose principal  business address is at
Four Falls Corporate Center, West Conshohocken, PA 19428.

The Board of  Directors  of the Company  approved  and adopted the  Distribution
Agreement  and  separate  Plans  of   Distribution   for  each  of  the  Classes
(collectively,  the  "Plans")  pursuant to Rule 12b-1 under the 1940 Act.  Under
each of the Plans,  the  Distributor  is entitled to receive  from the  relevant
Bedford Class a distribution fee, which is accrued daily and paid monthly, of up
to .65% on an  annualized  basis of the average daily net assets of the relevant
Bedford Class.  The actual amount of such  compensation is agreed upon from time
to time by the  Company's  Board of  Directors  and the  Distributor.  Under the
Distribution  Agreement,  the Distributor has agreed to accept  compensation for
its services thereunder and under the Plans in the amount of .60% of the average
daily net assets of the relevant  Class on an annualized  basis in any year. The
Distributor may, in its discretion,  voluntarily  waive from time to time all or
any portion of its distribution fee.

Under the  Distribution  Agreement and the relevant  Plan, the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and services  provided to  shareholders  of any relevant
Class  serviced  by  such  financial  institutions.  the  Distributor  may  also
reimburse  broker/dealers  for other  expenses  incurred in the promotion of the
sale of Bedford Shares. The Distributor  and/or  broker/dealers pay for the cost
of  printing  (excluding  typesetting)  and  mailing  to  prospective  investors
prospectuses and other materials  relating to the Bedford Classes as well as for
related direct mail, advertising and promotional expenses.

     Each of the Plans obligates the Company, during the period it is in effect,
to accrue and pay to the  Distributor  on behalf of each  Bedford  Class the fee
agreed to under the  Distribution  Agreement.  Payments  under the Plans are not
based on expenses  actually  incurred by the  Distributor,  and the payments may
exceed distribution expenses actually incurred.  Because these fees are paid out
of the funds'  assets on an on-going  basis,  over time these fees will increase
the cost of your  investment  and may cost you more than  paying  other types of
sales charges.

MUNICIPAL MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
                              IMPORTANT DEFINITIONS

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

GENERAL  OBLIGATION BONDS: Bonds which are secured by the issuer's pledge of its
full faith, credit and taxing power for the payment of principal and interest.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

MUNICIPAL  LEASE  OBLIGATIONS:  These provide  participation  in municipal lease
agreements and installment  purchase contracts,  but are not part of the general
obligations of the municipality.

MUNICIPAL SECURITY: A short-term obligation issued by or on behalf of states and
possessions  of the  United  States,  their  political  subdivisions  and  their
agencies and authorities.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REVENUE  BONDS:  Bonds which are secured only by the revenues  from a particular
facility or class of  facilities,  such as a water or sewer system,  or from the
proceeds of a special excise tax or other revenue source.

INVESTMENT GOAL

     The fund seeks to generate current income exempt from federal income taxes,
to provide you with liquidity and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve  this goal,  we invest in a  diversified  portfolio of Municipal
Securities.

     Specifically, we may invest in:

          1)   Fixed and variable rate notes and similar debt instruments  rated
               or issued by issuers who have  ratings at the time of purchase of
               MIG-2,  VMIG-2 or  Prime-2 or higher by  Moody's,  SP-2 or A-2 or
               higher by Standard & Poor's,  D-2 or higher by Duff & Phelps,  or
               F-2 or higher by Fitch (or  guaranteed or otherwise  supported by
               entities with such ratings).

          2)   Tax-exempt commercial paper and similar debt instruments rated or
               issued by issuers  who have  ratings at the time of  purchase  of
               Prime-2 or higher by Moody's, A-2 or higher by Standard & Poor's,
               D-2 or  higher  by Duff &  Phelps,  or F-2 or higher by Fitch (or
               guaranteed or otherwise supported by entities with such ratings).

          3)   Municipal  bonds rated or issued by issuers  who have  ratings at
               the time of  purchase  of Aa or higher by Moody's or AA or higher
               by Standard & Poor's,  Duff & Phelps or Fitch (or  guaranteed  or
               otherwise supported by entities with such ratings).

          4)   Unrated notes, paper and other instruments that are determined by
               us to be of  comparable  quality  to  the  instruments  described
               above.

          5)   Municipal bonds and notes whose  principal and interest  payments
               are  guaranteed by the U.S.  Government or one of its agencies or
               authorities or which otherwise depend on the credit of the United
               States.

     The fund seeks to maintain a net asset value of $1.00 per share.

     We normally  invest at least 80% of its net assets in Municipal  Securities
and other  instruments  whose  interest  is exempt  from  federal  income tax or
subject to the Federal Alternative Minimum Tax.

     The fund may hold  uninvested  cash  reserves  during  temporary  defensive
periods or, if in our opinion suitable  Municipal  Securities are not available.
The fund may hold all of its assets in uninvested cash reserves during temporary
defensive periods. Uninvested cash will not earn income.

     We  intend  to have no more  than  25% of its  total  assets  in  Municipal
Securities of issuers located in the same state.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain variable and floating rate  instruments)
will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Municipal  Securities  include revenue bonds,  general obligation bonds and
municipal lease obligations. Revenue bonds include private activity bonds, which
are not payable  from the general  revenues  of the  issuer.  Consequently,  the
credit  quality of private  activity  bonds is usually  directly  related to the
credit  standing of the corporate user of the facility  involved.  To the extent
that the fund's assets are invested in private  activity bonds, the fund will be
subject to the particular  risks  presented by the laws and economic  conditions
relating to such projects and bonds to a greater  extent than if its assets were
not so invested.  Moral  obligation bonds are normally issued by special purpose
public authorities. If the issuer of moral obligation bonds is unable to pay its
debts from current  revenues,  it may draw on a reserve fund the  restoration of
which is a moral but not a legal  obligation of the state or municipality  which
created  the  issuer.  Risk  exists  that a  municipality  will not honor  moral
obligation  bonds.  Municipal lease obligations are not guaranteed by the issuer
and are generally less liquid than other securities.

     There may be less  information  available  on the  financial  condition  of
issuers of Municipal  Securities  than for public  corporations.  The market for
municipal  bonds may be less liquid than for taxable  bonds.  This means that it
may be harder to buy and sell Municipal Securities, especially on short notice.

     The fund may invest in bonds whose  interest  may be subject to the Federal
Alternative  Minimum Tax. Interest received on these bonds by a taxpayer subject
to the Federal Alternative Minimum Tax is taxable.

     We may invest 25% or more of assets in Municipal  Securities whose interest
is paid solely from  revenues of similar  projects.  For  example,  the fund may
invest more than 25% of its assets in Municipal  Securities  related to water or
sewer  systems.  This type of  concentration  exposes  the fund to the legal and
economic risks relating to those projects.

     We  will  rely on  legal  opinions  of  counsel  to  issuers  of  Municipal
Securities  as to the  tax-free  status of  investments  and will not do our own
analysis regarding tax-free status.

     The fund may purchase variable and floating rate instruments. Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000.  While Year 2000 issues could have a negative  effect on the fund, BIMC is
currently working to avoid such problems.  BIMC, the fund's investment  adviser,
is  also  working  with  other  systems  providers  and  vendors  servicing  the
Portfolios to determine  their  systems'  ability to handle Year 2000  problems.
There is no  guarantee,  however,  that systems  will work  properly on or after
January 1, 2000.  Year 2000 problems may also hurt issuers whose  securities the
fund holds or securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1                                          0.35%

     *  The table does not  reflect  charges or credits  which  investors  might
        incur if they invest through a financial institution.

     1. BIMC has  voluntarily  undertaken  that a portion of its  management fee
        will not be imposed on the fund  during the  current  fiscal year ending
        August 31, 2000. As a result of the fee waiver,  current management fees
        of the fund are  0.09% of  average  daily  net  assets.  This  waiver is
        expected to remain in effect for the current fiscal year. However, it is
        voluntary  and can be modified  or  terminated  at any time  without the
        fund's consent.

     2. As a result of the fee waiver set forth in note 1, the total annual fund
        operating expenses which are estimated to be incurred during the current
        fiscal year are 0.89%. Although this fee waiver is expected to remain in
        effect  for  the  current  fiscal  year,  it is  voluntary  and  may  be
        terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your  actual  cost may be higher or lower,  based on
these assumptions your costs would be:

                      1 YEAR        3 YEARS         5 YEARS        10 YEARS

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated  by dividing a fund's  total
assets, less its liabilities, by the number of shares outstanding.

     Each fund values its securities  using amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may purchase Bedford Shares through an account  maintained by
your brokerage firm (the "Account") and you may also purchase Shares directly by
mail or  wire.  The  minimum  initial  investment  is  $1,000,  and the  minimum
subsequent  investment is $100. The Company in its sole discretion may accept or
reject any order for purchases of Bedford Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
an Account with your broker through  procedures and requirements  established by
your  broker.  In such event,  beneficial  ownership  of Bedford  Shares will be
recorded by your broker and will be reflected in the Account statements provided
to you by your  broker.  Your  broker  may  impose  minimum  investment  Account
requirements.  Even if your broker does not impose a sales charge for  purchases
of Bedford Shares,  depending on the terms of your Account with your broker, the
broker  may  charge to your  Account  fees for  automatic  investment  and other
services provided to your Account.  Information concerning Account requirements,
services and charges  should be obtained  from your broker,  and you should read
this Prospectus in conjunction  with any information  received from your broker.
Shares are held in the street  name  account of your broker and if you desire to
transfer  such shares to the street name account of another  broker,  you should
contact your current broker.

     A broker  with whom you  maintain  an Account  may offer you the ability to
purchase  Bedford  Shares  under an  automatic  purchase  program  (a  "Purchase
Program")  established  by a  participating  broker.  If  you  participate  in a
Purchase Program,  then you will have your  "free-credit"  cash balances in your
Account automatically invested in Shares of the



                                       13



<PAGE>



Bedford Class designated by you as the "Primary Bedford Class" for your Purchase
Program.  The frequency of investments  and the minimum  investment  requirement
will be established by the broker and the Company.  In addition,  the broker may
require a minimum  amount of cash  and/or  securities  to be  deposited  in your
Account  to  participate  in  its  Purchase  Program.  The  description  of  the
particular  broker's  Purchase  Program  should  be read  for  details,  and any
inquiries concerning your Account under a Purchase Program should be directed to
your  broker.  As a  participant  in a  Purchase  Program,  you may  change  the
designation  of the Primary  Bedford  Class at any time by so  instructing  your
broker.

     If your broker makes  special  arrangements  under which orders for Bedford
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees that payment for such Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase  order is received by PFPC.  Otherwise,  if the broker has not
made such an arrangement,  pricing of shares will occur as described above under
"General."

     DIRECT PURCHASES.  You may also make direct  investments at any time in any
Bedford  Class you select  through  any broker  that has  entered  into a dealer
agreement with the Distributor (a "Dealer").  You may make an initial investment
in any of the  Bedford  Classes  by mail by  fully  completing  and  signing  an
application obtained from a Dealer (the "Application"), specifying the Portfolio
in which you wish to invest,  and mailing it,  together  with a check payable to
"The Bedford Family" to the Bedford Family, c/o PFPC, P.O. Box 8950, Wilmington,
Delaware  19899.  The check must  specify  the name of the  Portfolio  for which
shares are being  purchased.  An  Application  will be returned to you unless it
contains the name of the Dealer from whom you obtained it. Subsequent  purchases
may be made through a Dealer or by forwarding  payment to the Company's transfer
agent at the foregoing address.

     Provided that your  investment  is at least  $2,500,  you may also purchase
Shares in any of the Bedford  Classes by having your bank or Dealer wire Federal
Funds to the Company's  Custodian,  PFPC Trust Company.  Your bank or Dealer may
impose a charge for this  service.  The Company  does not  currently  charge for
effecting wire transfers but reserves the right to do so in the future. In order
to ensure prompt receipt of your Federal Funds wire, for an initial  investment,
it is important that you follow these steps:

     A.   Telephone the Company's transfer agent, PFPC, toll-free (800) 533-7719
          and provide your name, address,  telephone number,  Social Security or
          Tax  Identification  Number,  the Bedford Class  selected,  the amount
          being wired,  and by which bank or Dealer.  PFPC will then provide you
          with an account number.  (If you have an existing account,  you should
          also notify PFPC prior to wiring funds.)

     B.   Instruct  your bank or Dealer to wire the specified  amount,  together
          with your assigned account number, to PFPC's account with PNC Bank.
          PNC Bank, N.A., Philadelphia, PA ABA-0310-0005-3.
          FROM: (your name)
          ACCOUNT NUMBER: (your account number with the Portfolio)
          FOR PURCHASE OF: (name of the Portfolio)
          AMOUNT: (amount to be invested)

     C.   Fully  complete  and sign the  Application  and mail it to the address
          shown  thereon.  PFPC  will not  process  initial  purchases  until it
          receives a fully completed and signed Application.

For subsequent investments, you should follow steps A and B above.



                                       14

     RETIREMENT  PLANS.  Bedford  Shares may be  purchased in  conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you beneficially own Bedford Shares
through an Account,  you may redeem Bedford Shares in your Account in accordance
with instructions and limitations  pertaining to your Account by contacting your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Your brokerage firm may also redeem each day a sufficient  number of Shares
of the Primary Bedford Class to cover debit balances  created by transactions in
your Account or instructions for cash disbursements.  Shares will be redeemed on
the same day that a  transaction  occurs that results in such a debit balance or
charge.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem any number of Shares by sending a written  request to The Bedford  Family
c/o PFPC, P.O. Box 8950, Wilmington, Delaware 19899. Redemption requests must be
signed by each  shareholder  in the same  manner as the Shares  are  registered.
Redemption  requests  for joint  accounts  require the  signature  of each joint
owner.  On  redemption  requests  of  $5,000  or more,  each  signature  must be
guaranteed.  A signature guarantee may be obtained from a domestic bank or trust
company,  broker,  dealer,  clearing  agency  or  savings  association  who  are
participants  in a  medallion  program  recognized  by the  Securities  Transfer
Association.  The three recognized  medallion  programs are Securities  Transfer
Agents Medallion Program (STAMP),  Stock Exchanges  Medallion Program (SEMP) and
New York Stock  Exchange,  Inc.  Medallion  Signature  Program (MSP).  Signature
guarantees that are not part of these programs will not be accepted.

     If you are a direct investor,  you may redeem your Shares without charge by
telephone if you have completed and returned an account  application  containing
the appropriate  telephone  election.  To add a telephone  option to an existing
account  that  previously  did not  provide  for this  option,  you must  file a
Telephone  Authorization  Form with PFPC. This form is available from PFPC. Once
this election has been made, you may simply contact PFPC by telephone to request
the redemption by calling (800) 533-7719.  Neither the Company, the Distributor,
the Portfolios, the Administrator nor any other Company agent will be liable for
any loss,  liability,  cost or expense for following the procedures below or for
following instructions communicated by telephone that they reasonably believe to
be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and name of the portfolio,  all of which must match the
Company's  records;  (3)  requiring  the  Company's  service  representative  to
complete a telephone transaction form, listing all of the above caller iden-

                                       15
<PAGE>
tification  information;  (4) requiring that redemption proceeds be sent only by
check to the account owners of record at the address of record,  or by wire only
to the owners of record at the bank  account of  record;  (5)  sending a written
confirmation  for each  telephone  transaction  to the  owners  of record at the
address of record within five (5) business days of the call; and (6) maintaining
tapes of telephone  transactions for six months, if the Company elects to record
shareholder   telephone   transactions.   For   accounts   held  of   record  by
broker-dealers (other than the Distributor), financial institutions,  securities
dealers,   financial  planners  or  other  industry  professionals,   additional
documentation  or  information  regarding  the scope of  authority  is required.
Finally,  for  telephone  transactions  in  accounts  held  jointly,  additional
information regarding other account holders is required.  Telephone transactions
will not be permitted in connection  with IRA or other  retirement plan accounts
or by attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have designated in your  Application or Telephone
Authorization  Form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account  on the next day  that a wire  transfer  can be  effected.  The  minimum
redemption for proceeds sent by wire transfer is $2,500. There is no maximum for
proceeds sent by wire transfer.  The Company may modify this redemption  service
at any time or charge a service fee upon prior notice to shareholders,  although
no fee is currently contemplated.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $100; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves the right to redeem any account in a Bedford  Class  involuntarily,  on
thirty days'  notice,  if such  account  falls below $500 and during such 30-day
notice  period the amount  invested in such account is not increased to at least
$500.  Payment for Shares  redeemed may be postponed or the right of  redemption
suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment

                                       16
<PAGE>



of redemptions.  The funds have elected,  however,  to be governed by Rule 18f-1
under the 1940 Act, so that a fund is obligated  to redeem its Shares  solely in
cash up to the lesser of $250,000 or 1% of its net asset value during any 90-day
period for any one shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and net realized capital gains, if any, of the fund to the fund's  shareholders.
All  distributions  are reinvested in the form of additional full and fractional
Shares of the relevant Bedford Class unless a shareholder elects otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by each fund will be  declared  as a dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the Municipal  Money Market  Portfolio  will  generally
constitute  tax-exempt  income for shareholders for federal income tax purposes.
It is possible,  depending upon the Portfolio's  investments,  that a portion of
the  Portfolio's  distributions  could be taxable to  shareholders  as  ordinary
income or capital gains, but it is not expected that this will be the case.

     Interest on  indebtedness  incurred by a  shareholder  to purchase or carry
shares of the Municipal Money Market Portfolio  generally will not be deductible
for federal income tax purposes.

     You should note that a portion of the exempt-interest dividends paid by the
Municipal  Money Market  Portfolio may  constitute an item of tax preference for
purposes   of   determining   federal   alternative   minimum   tax   liability.
Exempt-interest  dividends  will also be  considered  along with other  adjusted
gross income in determining  whether any Social Security or railroad  retirement
payments received by you are subject to federal income taxes.

     Although distributions from the Municipal Money Market Portfolio are exempt
for federal income tax purposes,  they will generally  constitute taxable income
for state and local income tax purposes except that, subject to limitations that
vary  depending on the state,  distributions  from  interest  paid by a state or
municipal entity may be exempt from tax in that state.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Bedford  Shares of the fund are sold  without a sales load on a  continuous
basis by Provident  Distributors,  Inc., whose principal  business address is at
Four Falls Corporate Center, West Conshohocken, PA 19428.

     The Board of Directors of the Company approved and adopted the Distribution
Agreement and a Plan of Distribution for the Class (the "Plan") pursuant to Rule
12b-1 under the 1940 Act. Under the Plan, the Distributor is entitled to receive
from the  Bedford  Class a  distribution  fee,  which is accrued  daily and paid
monthly, of up to .65% on an annualized basis of the average daily net assets of
the Bedford Class.  The actual amount of such  compensation  is agreed upon from
time to time by the Company's Board of Directors and the Distributor.  Under the
Distribution  Agreement,  the Distributor has agreed to accept  compensation for
its services  thereunder and under the Plan in the amount of .60% of the average
daily  net  assets  of  the  Class  on an  annualized  basis  in any  year.  The
Distributor may, in its discretion,  voluntarily  waive from time to time all or
any portion of its distribution fee.

     Under  the  Distribution  Agreement  and  the  Plan,  the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and  services  provided  to  shareholders  of the  Class
serviced by such  financial  institutions.  The  Distributor  may also reimburse
broker/dealers  for other  expenses  incurred  in the  promotion  of the sale of
Bedford  Shares.  The  Distributor  and/or  broker/dealers  pay for the  cost of
printing   (excluding   typesetting)   and  mailing  to  prospective   investors
prospectuses  and other  materials  relating to the Bedford Class as well as for
related direct mail, advertising and promotional expenses.

     The Plan  obligates  the  Company,  during the  period it is in effect,  to
accrue and pay to the  Distributor on behalf of the Bedford Class the fee agreed
to under the  Distribution  Agreement.  Payments under the Plan are not based on
expenses  actually  incurred by the  Distributor,  and the  payments  may exceed
distribution expenses actually incurred.  Because these fees are paid out of the
fund's assets on an on-going basis,  over time these fees will increase the cost
of your  investment  and may cost  you more  than  paying  other  types of sales
charges.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                             IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES.

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)U.S. dollar-denominated  obligations issued or supported by the credit of
       U.S. or foreign banks or savings  institutions  with total assets of more
       than $1  billion  (including  obligations  of  foreign  branches  of such
       banks).

     2)High quality  commercial paper and other obligations issued or guaranteed
       (or  otherwise  supported)  by U.S.  and foreign  corporations  and other
       issuers  rated (at the time of  purchase)  A-2 or higher by Standard  and
       Poor's, Prime-2 or higher by Moody's, D-2 or higher by Duff & Phelps, F-2
       or higher by Fitch or TBW-2 or higher by  Thomson  BankWatch,  as well as
       high  quality  corporate  bonds rated AA (or Aa) or higher at the time of
       purchase by those rating  agencies.  These ratings must be provided by at
       least two rating  agencies,  or by the only  rating  agency  providing  a
       rating.

     3)Unrated notes,  paper and other  instruments that are determined by us to
       be of comparable quality to the instruments described above.

     4)Asset-backed  securities  (including interests in pools of assets such as
       mortgages, installment purchase obligations and credit card receivables).

     5)Securities  issued  or  guaranteed  by  the  U.S.  Government  or by  its
       agencies or authorities.

     6)Dollar-denominated   securities   issued   or   guaranteed   by   foreign
       governments or their political subdivisions, agencies or authorities.

     7) Securities issued or guaranteed by state or local governmental bodies.

     8)Repurchase  agreements relating to the above instruments.  The fund seeks
       to maintain a net asset value of $1.00 per share.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

                                       6

<PAGE>

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay pricipal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

RISK / RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for

================================================================================

EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

     Annual Fund Operating Expenses*
     (Expenses that are deducted from fund assets)

     Management Fees 1 .............................    0.36%
     Distribution and service (12b-1) fees .........    0.59%
     Other expenses ................................    0.13%

                                                        =====

     * The table does not reflect charges or credits which investors might incur
       if they invest through a financial institution.

     1.BIMC has  voluntarily  undertaken  that a portion of its  management  fee
       will not be imposed on the fund  during the  current  fiscal  year ending
       August 31, 2000. As a result of the fee waiver,  current  management fees
       of the fund are  0.25% of  average  daily  net  assets.  This  waiver  is
       expected to remain in effect for the current fiscal year.  However, it is
       voluntary  and can be  modified  or  terminated  at any time  without the
       fund's consent.

     2.As a result of the fee waiver set forth in note 1, the total  annual fund
       operating  expenses which are estimated to be incurred during the current
       fiscal year are 0.97%.  Although this fee waiver is expected to remain in
       effect for the current fiscal year, it is voluntary and may be terminated
       at any time at the option of BIMC.

     EXAMPLE:

     This  example is intended to help you compare the cost of  investing in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                        1 YEAR         3 YEARS        5 YEARS       10 YEARS

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated by dividing the fund's total
assets, less its liabilities, by the number of shares outstanding.

     The fund values its securities  using  amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may  purchase  Shares  directly,  through  an  exchange  from
accounts  invested  in shares of any  open-end  investment  company  ("The  Bear
Stearns  Funds")  either  sponsored by or advised by Bear,  Stearns & Co.,  Inc.
("Bear  Stearns") or its  affiliates.  You may also purchase  Shares  through an
account maintained by your brokerage firm (the "Account") or directly by mail or
wire.  The minimum  initial  investment  is $1,000,  and the minimum  subsequent
investment is $250. The Company in its sole  discretion may accept or reject any
order for purchases of Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal  Funds  immediately  available to it. A
"Business Day" is any day that both the New York Stock Exchange (the "NYSE") and
the Federal Reserve Bank of  Philadelphia  (the "FRB") are open. On any Business
Day,  orders which are  accompanied by Federal Funds and received by the Company
by 12:00 noon Eastern Time,  and orders as to which  payment has been  converted
into Federal Funds by 12:00 noon Eastern Time, will be executed as of 12:00 noon
that Business Day. Orders which are accompanied by Federal Funds and received by
PFPC after 12:00 noon Eastern Time but prior to the close of regular  trading on
the NYSE (generally 4:00 p.m.  Eastern Time), and orders as to which payment has
been converted into Federal Funds after 12:00 noon Eastern Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     If your broker makes  special  arrangements  under which orders for Bedford
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees  that payment for the Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase order is received by PFPC.

     PURCHASES  THROUGH AN ACCOUNT  (other than accounts held by Bear Stearns or
brokers who have clearing  arrangements with Bear Stearns).  Purchases of Shares
may be effected  through an Account  with your  broker  through  procedures  and
requirements  established by your broker. In such event, beneficial ownership of
Shares  will be recorded  by your  broker and will be  reflected  in the Account
statements  provided  to you by your  broker.  Your  broker may  impose  minimum
investment  Account  requirements.  Even if your  broker does not impose a sales
charge for purchases of Bedford  Shares,  depending on the terms of your Account
with your  broker,  the  broker may charge to your  Account  fees for  automatic
investment and other services provided to your Account.  Information  concerning
Account requirements,  services and charges should be obtained from your broker,
and you should read this Prospectus in conjunction with any information received
from your broker.  Shares are held in the street name account of your broker and
if you desire to  transfer  such  shares to the street  name  account of another
broker, you should contact your current broker.

     If you are a  shareholder  of The  Bear  Stearns  Funds,  you may  purchase
Bedford Shares in exchange for shares of The Bear Stearns  Funds.  This exchange
privilege is only available if you have an existing account.
See "Exchange Privilege" below.

     For distribution services with respect to Bedford Shares held by clients of
Bear Stearns, the Company's  Distributor will pay Bear Stearns up to .50% of the
annual average value of such accounts.

     DIRECT PURCHASES.  You may make an initial  investment in Bedford Shares by
mail by fully  completing and signing an  application  (the  "Application")  and
mailing  it,  together  with a check  payable  to "The RBB Fund -- Money  Market
Portfolio  (Bedford Class)," to Bedford Money Market  Portfolio,  c/o PFPC, P.O.
Box  8960,  Wilmington,  Delaware  19899.  Subsequent  purchases  may be made by
forwarding payment to the Company's transfer agent at the foregoing address.

                                       13

<PAGE>

     You may also  purchase  Shares by having your bank or broker  wire  Federal
Funds to the Company's  Custodian,  PFPC Trust Company.  Your bank or broker may
impose a charge for this  service.  The Company  does not  currently  charge for
effecting wire transfers but reserves the right to do so in the future. In order
to ensure prompt receipt of your Federal Funds wire, for an initial  investment,
it is important that you follow these steps:

        A.  Telephone  the  Company's  transfer  agent,  PFPC,  toll-free  (800)
            447-1139,  and provide your name, address,  telephone number, Social
            Security or Tax  Identification  Number, the amount being wired, and
            by which bank or broker.  PFPC will then provide you with an account
            number.  (If you have an  existing  account,  you should also notify
            PFPC prior to wiring funds.)

        B.  Instruct your bank or broker to wire the specified amount,  together
            with your assigned account number,  to PFPC's account with PNC Bank.
            PNC Bank, N.A.,  Philadelphia,  PA
            ABA-0310-0005-3.
            CREDIT ACCOUNT NUMBER: 85-5102-0143
            FROM: (your name)
            ACCOUNT NUMBER: (your account number)
            FOR  PURCHASE  OF: The RBB Fund -- Money  Market  Portfolio
              (Bedford Class)
            AMOUNT: (amount to be invested)

        C.  Fully complete and sign the  Application  and mail it to the address
            shown thereon. PFPC will not process redemptions until it receives a
            fully completed and signed Application.

     For subsequent investments, you should follow steps A and B above.

     RETIREMENT  PLANS.  Bedford  Shares may be  purchased in  conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you beneficially own Bedford Shares
through an  Account,  you may redeem  them in your  Account in  accordance  with
instructions  and  limitations  pertaining  to your Account by  contacting  your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem  any  number of Shares by  sending a written  request  to The RBB Fund --
Money Market  Portfolio  (Bedford Class),  c/o PFPC, P.O. Box 8960,  Wilmington,
Delaware 19899.  Redemption  requests must be signed by each  shareholder in the
same manner as the Shares are registered. Redemption requests for joint accounts
require the signature of each joint owner.  On redemption  requests of $5,000 or
more, each signature must be guaranteed.  A signature  guarantee may be obtained
from a  domestic  bank or trust  company,  broker,  dealer,  clearing  agency or
savings  association who are participants in a medallion  program  recognized by
the Securities Transfer Association. The three recognized medallion programs are
Securities Transfer Agents Medallion Program (STAMP),  Stock Exchanges Medallion
Program (SEMP) and New York Stock Exchange,  Inc.  Medallion  Signature  Program
(MSP).  Signature  guarantees  that are not part of these  programs  will not be
accepted.

                                       14

<PAGE>

     REDEMPTION BY TELEPHONE.  If you are a direct investor, you may redeem your
Shares without charge by telephone if you have completed and returned an account
application  containing the appropriate  telephone election.  To add a telephone
option to an existing  account that  previously did not provide for this option,
you should contact the transfer agent, PFPC, at (800) 447-1139.

     Once you are  authorized  to utilize the  telephone  redemption  option,  a
redemption  of Shares may be  requested  by calling  PFPC at (800)  447-1139 and
requesting  that the redemption  proceeds be mailed to the primary  registration
address or wired per the authorized  instructions.  If the telephone  redemption
option or the telephone exchange option (as described below) is authorized, PFPC
may act on  telephone  instructions  from any  person  representing  himself  or
herself to be a shareholder  and believed by PFPC to be genuine.  PFPC's records
of such instructions are binding and shareholders, not the Company or PFPC, bear
the risk of loss in the event of unauthorized  instructions  reasonably believed
by the Company or PFPC to be genuine.  PFPC will employ reasonable procedures to
confirm that  instructions  communicated are genuine and, if it does not, it may
be liable for any losses due to  unauthorized  or fraudulent  instructions.  The
procedures  employed  by PFPC  in  connection  with  transactions  initiated  by
telephone  include tape recording of telephone  instructions  and requiring some
form of personal  identification  prior to acting upon instructions  received by
telephone.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address  unless you have  designated in your  Application  that such
proceeds  are to be sent by wire  transfer  to a  specified  checking or savings
account.  If proceeds are to be sent by wire  transfer,  a telephone  redemption
request  received prior to the close of regular  trading on the NYSE will result
in redemption  proceeds  being wired to your bank account on the next day that a
wire transfer can be effected.  The minimum redemption for proceeds sent by wire
transfer is $2,500. There is no maximum for proceeds sent by wire transfer.  The
Company may modify this  redemption  service at any time or charge a service fee
upon prior notice to shareholders, although no fee is currently contemplated.

     DURING TIMES OF DRASTIC ECONOMIC OR MARKET  CONDITIONS,  YOU MAY EXPERIENCE
DIFFICULTY  IN  CONTACTING  BEAR  STEARNS,  THE  DISTRIBUTOR  OR YOUR  BROKER BY
TELEPHONE TO REQUEST A REDEMPTION OF SHARES.  IN SUCH CASES, YOU SHOULD CONSIDER
USING  THE OTHER  REDEMPTION  PROCEDURES  DESCRIBED  ABOVE.  USE OF THESE  OTHER
REDEMPTION  PROCEDURES MAY RESULT IN THE REDEMPTION REQUEST BEING PROCESSED AT A
LATER TIME THAN IT WOULD HAVE BEEN IF TELEPHONE REDEMPTION HAD BEEN USED.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $250; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     AUTOMATIC   WITHDRAWAL.   Automatic   withdrawal  permits  you  to  request
withdrawal of a specified  dollar amount (minimum of $25) on either a monthly or
quarterly basis if the investor has a $5,000 minimum account.  You can obtain an
application for automatic  withdrawal from Bear Stearns,  the Distributor,  your
broker, or the transfer agent.  Automatic withdrawal may be ended at any time by
either you, the Company or the  transfer  agent.  Shares for which  certificates
have been issued may not be redeemed through automatic withdrawal.  Purchases of
additional shares concurrently with withdrawals generally are undesirable.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form. However, if you bought your Shares by check, the Company
will  wait for your  check to clear  (up to 15  days)  before  it  accepts  your
redemption  request.  This procedure does not apply to Shares  purchased by wire
payment.  You should consider  purchasing Shares using a certified or bank check
or money order if you anticipate an immediate need for redemption proceeds.

                                       15

<PAGE>

     The Company  does not impose a charge when Shares are  redeemed,  except as
described  below.  The Company  reserves  the right to redeem any account in the
Bedford Class involuntarily, on thirty days' notice, if such account falls below
$500 and during such 30-day notice period the amount invested in such account is
not increased to at least $500.  Payment for Shares redeemed may be postponed or
the right of redemption suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lessor of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a fund.

EXCHANGE PRIVILEGE

     The exchange  privilege  enables you to purchase Bedford Shares in exchange
for shares of the other mutual funds  sponsored or advised by Bear  Stearns,  to
the extent such shares are  offered for sale in your state of  residence.  These
funds have different investment objectives than the fund. To use this privilege,
you should  consult your  account  executive at Bear  Stearns,  your  investment
dealers who have sales  agreements  with Bear  Stearns,  the  Distributor,  your
broker or the transfer  agent to  determine  if it is available  and whether any
conditions  are imposed on its use.  Currently,  exchanges may be made among the
following  portfolios (and such additional  portfolios which may be added in the
future):
         -    S&P STARS Portfolio
         -    Large Cap Value Portfolio
         -    Small Cap Value Portfolio
         -    The Insiders Select Fund
         -    International Equity Portfolio
         -    Focus List Portfolio
         -    Balanced Portfolio
     To effect an exchange of Shares, exchange instructions must be given to the
transfer agent in writing or by telephone. If you wish to make an exchange, send
a written  request to PFPC,  Attention:  The RBB Fund -- Money Market  Portfolio
(Bedford  Class),   P.O.  Box  8960,   Wilmington,   Delaware  19899.  You  will
automatically  be provided with telephone  exchange  privileges  when opening an
account,  unless you indicate otherwise on the account application.  If you hold
share certificates, you are not eligible to exchange shares of the fund by phone
because share  certificates  must accompany all exchange  requests.  To add this
feature to an existing  account that previously did not provide for this option,
a Telephone  Authorization Form must be filed with the transfer agent. This form
is available from the transfer agent. Once you have made this election,  you may
contact  the  transfer  agent by  telephone  at (800)  447-1139  to request  the
exchange.  See "Redemption of Shares--Redemption by Telephone" for a description
of the Company's telephone transaction procedures. During periods of substantial
economic or market change,  telephone exchanges may be difficult to complete and
shareholders  may have to submit  exchange  requests  to the  transfer  agent in
writing.

     If you do not currently own Bedford Shares or a fund whose shares are being
acquired, a new account will be established with the same registration, dividend
and capital gain options and the same dealer of record as the account from which
shares  are  exchanged,  unless  you  specify  otherwise  in  writing  with  all
signatures  guaranteed  as  described  above.  To  participate  in an  automatic
investment plan or establish automatic withdrawal for the new account,  however,
you must file a specific  written  request before the exchange can be processed.
The exchange  privilege  may be modified or terminated at any time, or from time
to time,  by the  Company  on 60 days'  notice  to  affected  portfolio  or fund
shareholders.

     Before  any  exchange,  you must  obtain  and  should  review a copy of the
current  prospectus  of the  portfolio  or fund into which the exchange is being
made.  Prospectuses  may be obtained  from Bear  Stearns.  Except in the case of
Personal  Retirement Plans, the Shares being exchanged must have a current value
of at least $250; furthermore,  when establishing a new account by exchange, the
shares  being  exchanged  must  have a value of at  least  the  minimum  initial
investment  required for the  portfolio or fund into which the exchange is being
made. If making an exchange to an existing account,  the dollar value must equal
or exceed the  applicable  minimum  for  subsequent  investments.  If any amount
remains in the investment  portfolio from which the exchange is being made, such
amount must not be below the minimum  account value required by the portfolio or
fund.

     Shares will be exchanged at the next  determined  public offering price. To
qualify for the exchange privilege, at the time of the exchange, you must notify
Bear Stearns, the Distributor, your investment dealer or the transfer agent. Any
such  qualification  is subject to confirmation of your holdings through a check
of  appropriate  records.  No fees  currently  are  charged  directly to you for
exchanges,  although the Company reserves the right, upon not less than 60 days'
written notice,  to charge a $5.00 fee in accordance  with rules  promulgated by
the SEC. The Company  reserves the right to reject any exchange request in whole
or in part.  The Exchange  Privilege  may be modified or  terminated at any time
upon notice to shareholders.

     The  exchange of shares of one  portfolio  or fund for shares of another is
treated  for  federal  income  tax  purposes  as a sale of the  shares  given in
exchange by the  shareholder  and,  therefore,  an  exchanging  shareholder  may
realize a taxable gain or loss.

REDIRECTED  DISTRIBUTION OPTION. The Redirected  Distribution Option enables you
to invest  automatically  dividends or dividends and capital gain distributions,
if any, paid by the fund in shares of another portfolio of the Company or a fund
advised or sponsored  by Bear  Stearns in which you invest.  Shares of the other
portfolio or fund will be purchased at the then current public  offering  price.
If you are  investing in a fund that  charges a sales load,  you may qualify for
share  prices  which do not  include  the sales load or which  reflect a reduced
sales load.

This  privilege is available  only for existing  accounts and may not be used to
open new accounts.  Minimum subsequent investments do not apply. The Company may
modify or terminate this privilege at any time or charge a service fee. However,
no such fee currently is contemplated.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and net realized capital gains, if any, of the fund to the fund's  shareholders.
All  distributions  are reinvested in the form of additional full and fractional
Shares of the Class unless a shareholder elects otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by the fund will be  declared  as a  dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the Money Market Portfolio will generally be taxable to
shareholders.   It  is  expected  that  all,  or  substantially  all,  of  these
distributions will consist of ordinary income. You will be subject to income tax
on these distributions regardless of whether they are paid in cash or reinvested
in additional  shares.  The one major  exception to these tax principles is that
distributions on shares held in an IRA (or other tax-qualified plan) will not be
currently taxable.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Bedford Shares of the Money Market  Portfolio are sold without a sales load
on a continuous basis by Provident Distributors,  Inc., whose principal business
address is at Four Falls Corporate Center, West Conshohocken, PA 19428.

     The Board of Directors of the Company approved and adopted the Distribution
Agreement and Plan of Distribution  for the Class (the "Plan")  pursuant to Rule
12b-1 under the 1940 Act. Under the Plan, the Distributor is entitled to receive
from the Class a distribution  fee, which is accrued daily and paid monthly,  of
up to .65% on an annualized  basis of the average daily net assets of the Class.
The actual amount of such  compensation  is agreed upon from time to time by the
Company's  Board  of  Directors  and the  Distributor.  Under  the  Distribution
Agreement,  the Distributor has agreed to accept  compensation  for its services
thereunder  and under the Plan in the  amount of .60% of the  average  daily net
assets of the Class on an annualized  basis in any year. The Distributor may, in
its  discretion,  voluntarily  waive from time to time all or any portion of its
distribution fee.

     Under  the  Distribution  Agreement  and  the  Plan,  the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and  services  provided  to  shareholders  of the  Class
serviced by such  financial  institutions.  The  Distributor  may also reimburse
broker/dealers  for other  expenses  incurred  in the  promotion  of the sale of
Bedford  Shares.  The  Distributor  and/or  broker/dealers  pay for the  cost of
printing   (excluding   typesetting)   and  mailing  to  prospective   investors
prospectuses  and other  materials  relating to the Class as well as for related
direct mail, advertising and promotional expenses.

     The Plan  obligates  the  Company,  during the  period it is in effect,  to
accrue and pay to the Distributor on behalf of the Class the fee agreed to under
the  Distribution  Agreement.  Payments under the Plan are not based on expenses
actually incurred by the Distributor,  and the payments may exceed  distribution
expenses actually incurred. Because these fees are paid out of the fund's assets
on an  on-going  basis,  over time  these  fees will  increase  the cost of your
investment and may cost you more than paying other types of sales charges.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                             IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES.

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)U.S. dollar-denominated  obligations issued or supported by the credit of
       U.S. or foreign banks or savings  institutions  with total assets of more
       than $1  billion  (including  obligations  of  foreign  branches  of such
       banks).

     2)High quality  commercial paper and other obligations issued or guaranteed
       (or  otherwise  supported)  by U.S.  and foreign  corporations  and other
       issuers  rated (at the time of  purchase)  A-2 or higher by Standard  and
       Poor's, Prime-2 or higher by Moody's, D-2 or higher by Duff & Phelps, F-2
       or higher by Fitch or TBW-2 or higher by  Thomson  BankWatch,  as well as
       high  quality  corporate  bonds rated AA (or Aa) or higher at the time of
       purchase by those rating  agencies.  These ratings must be provided by at
       least two rating  agencies,  or by the only  rating  agency  providing  a
       rating.

     3)Unrated notes,  paper and other  instruments that are determined by us to
       be of comparable quality to the instruments described above.

     4)Asset-backed  securities  (including interests in pools of assets such as
       mortgages, installment purchase obligations and credit card receivables).

     5)Securities  issued  or  guaranteed  by  the  U.S.  Government  or by  its
       agencies or authorities.

     6)Dollar-denominated   securities   issued   or   guaranteed   by   foreign
       governments or their political subdivisions, agencies or authorities.

     7) Securities issued or guaranteed by state or local governmental bodies.

     8)Repurchase  agreements relating to the above instruments.  The fund seeks
       to maintain a net asset value of $1.00 per share.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

                                       6

<PAGE>

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay pricipal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

RISK / RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Bedford Shares.  The information shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Bedford Shares of the fund. The table is based on expenses for the most
recent fiscal year.

     Annual Fund Operating Expenses*
     (Expenses that are deducted from fund assets)

     Management Fees 1 .............................    0.36%
     Distribution and service (12b-1) fees .........    0.59%
     Other expenses ................................    0.13%
                                                        -----
     Total annual fund operating expenses 2 ........    1.08%
                                                        =====

     * The table does not reflect charges or credits which investors might incur
       if they invest through a financial institution.

     1.BIMC has  voluntarily  undertaken  that a portion of its  management  fee
       will not be imposed on the fund  during the  current  fiscal  year ending
       August 31, 2000. As a result of the fee waiver,  current  management fees
       of the fund are  0.25% of  average  daily  net  assets.  This  waiver  is
       expected to remain in effect for the current fiscal year.  However, it is
       voluntary  and can be  modified  or  terminated  at any time  without the
       fund's consent.

     2.As a result of the fee waiver set forth in note 1, the total  annual fund
       operating  expenses which are estimated to be incurred during the current
       fiscal year are 0.97%.  Although this fee waiver is expected to remain in
       effect for the current fiscal year, it is voluntary and may be terminated
       at any time at the option of BIMC.

     EXAMPLE:

     This  example is intended to help you compare the cost of  investing in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                        1 YEAR         3 YEARS        5 YEARS       10 YEARS

     The table below sets forth certain  financial  information  for the periods
indicated,  including per share information results for a single fund share. The
term "Total Return"  indicates how much your investment  would have increased or
decreased  during this period of time and assumes that you have  reinvested  all
dividends and  distributions.  This information has been derived from the fund's
financial  statements  audited  by  PricewaterhouseCoopers  LLP,  the  Company's
independent accountants. This information should be read in conjunction with the

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated by dividing the fund's total
assets, less its liabilities, by the number of shares outstanding.

     The fund values its securities  using  amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may  purchase  Shares  directly,  through  an  exchange  from
accounts  invested  in shares of any  open-end  investment  company  ("The  Bear
Stearns  Funds")  either  sponsored by or advised by Bear,  Stearns & Co.,  Inc.
("Bear  Stearns") or its  affiliates.  You may also purchase  Shares  through an
account maintained by your brokerage firm (the "Account") or directly by mail or
wire.  The minimum  initial  investment  is $1,000,  and the minimum  subsequent
investment is $250. The Company in its sole  discretion may accept or reject any
order for purchases of Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal  Funds  immediately  available to it. A
"Business Day" is any day that both the New York Stock Exchange (the "NYSE") and
the Federal Reserve Bank of  Philadelphia  (the "FRB") are open. On any Business
Day,  orders which are  accompanied by Federal Funds and received by the Company
by 12:00 noon Eastern Time,  and orders as to which  payment has been  converted
into Federal Funds by 12:00 noon Eastern Time, will be executed as of 12:00 noon
that Business Day. Orders which are accompanied by Federal Funds and received by
PFPC after 12:00 noon Eastern Time but prior to the close of regular  trading on
the NYSE (generally 4:00 p.m.  Eastern Time), and orders as to which payment has
been converted into Federal Funds after 12:00 noon Eastern Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     If your broker makes  special  arrangements  under which orders for Bedford
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees  that payment for the Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase order is received by PFPC.

     PURCHASES  THROUGH AN ACCOUNT  (other than accounts held by Bear Stearns or
brokers who have clearing  arrangements with Bear Stearns).  Purchases of Shares
may be effected  through an Account  with your  broker  through  procedures  and
requirements  established by your broker. In such event, beneficial ownership of
Shares  will be recorded  by your  broker and will be  reflected  in the Account
statements  provided  to you by your  broker.  Your  broker may  impose  minimum
investment  Account  requirements.  Even if your  broker does not impose a sales
charge for purchases of Bedford  Shares,  depending on the terms of your Account
with your  broker,  the  broker may charge to your  Account  fees for  automatic
investment and other services provided to your Account.  Information  concerning
Account requirements,  services and charges should be obtained from your broker,
and you should read this Prospectus in conjunction with any information received
from your broker.  Shares are held in the street name account of your broker and
if you desire to  transfer  such  shares to the street  name  account of another
broker, you should contact your current broker.

     If you are a  shareholder  of The  Bear  Stearns  Funds,  you may  purchase
Bedford Shares in exchange for shares of The Bear Stearns  Funds.  This exchange
privilege is only available if you have an existing account.
See "Exchange Privilege" below.

     For distribution services with respect to Bedford Shares held by clients of
Bear Stearns, the Company's  Distributor will pay Bear Stearns up to .50% of the
annual average value of such accounts.

     DIRECT PURCHASES.  You may make an initial  investment in Bedford Shares by
mail by fully  completing and signing an  application  (the  "Application")  and
mailing  it,  together  with a check  payable  to "The RBB Fund -- Money  Market
Portfolio  (Bedford Class)," to Bedford Money Market  Portfolio,  c/o PFPC, P.O.
Box  8960,  Wilmington,  Delaware  19899.  Subsequent  purchases  may be made by
forwarding payment to the Company's transfer agent at the foregoing address.

                                       13

     You may also  purchase  Shares by having your bank or broker  wire  Federal
Funds to the Company's  Custodian,  PFPC Trust Company.  Your bank or broker may
impose a charge for this  service.  The Company  does not  currently  charge for
effecting wire transfers but reserves the right to do so in the future. In order
to ensure prompt receipt of your Federal Funds wire, for an initial  investment,
it is important that you follow these steps:

        A.  Telephone  the  Company's  transfer  agent,  PFPC,  toll-free  (800)
            447-1139,  and provide your name, address,  telephone number, Social
            Security or Tax  Identification  Number, the amount being wired, and
            by which bank or broker.  PFPC will then provide you with an account
            number.  (If you have an  existing  account,  you should also notify
            PFPC prior to wiring funds.)

        B.  Instruct your bank or broker to wire the specified amount,  together
            with your assigned account number,  to PFPC's account with PNC Bank.
            PNC Bank, N.A.,  Philadelphia,  PA
            ABA-0310-0005-3.
            CREDIT ACCOUNT NUMBER: 85-5102-0143
            FROM: (your name)
            ACCOUNT NUMBER: (your account number)
            FOR  PURCHASE  OF: The RBB Fund -- Money  Market  Portfolio
              (Bedford Class)
            AMOUNT: (amount to be invested)

        C.  Fully complete and sign the  Application  and mail it to the address
            shown thereon. PFPC will not process redemptions until it receives a
            fully completed and signed Application.

     For subsequent investments, you should follow steps A and B above.

     RETIREMENT  PLANS.  Bedford  Shares may be  purchased in  conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you beneficially own Bedford Shares
through an  Account,  you may redeem  them in your  Account in  accordance  with
instructions  and  limitations  pertaining  to your Account by  contacting  your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem  any  number of Shares by  sending a written  request  to The RBB Fund --
Money Market  Portfolio  (Bedford Class),  c/o PFPC, P.O. Box 8960,  Wilmington,
Delaware 19899.  Redemption  requests must be signed by each  shareholder in the
same manner as the Shares are registered. Redemption requests for joint accounts
require the signature of each joint owner.  On redemption  requests of $5,000 or
more, each signature must be guaranteed.  A signature  guarantee may be obtained
from a  domestic  bank or trust  company,  broker,  dealer,  clearing  agency or
savings  association who are participants in a medallion  program  recognized by
the Securities Transfer Association. The three recognized medallion programs are
Securities Transfer Agents Medallion Program (STAMP),  Stock Exchanges Medallion
Program (SEMP) and New York Stock Exchange,  Inc.  Medallion  Signature  Program
(MSP).  Signature  guarantees  that are not part of these  programs  will not be
accepted.

     REDEMPTION BY TELEPHONE.  If you are a direct investor, you may redeem your
Shares without charge by telephone if you have completed and returned an account
application  containing the appropriate  telephone election.  To add a telephone
option to an existing  account that  previously did not provide for this option,
you should contact the transfer agent, PFPC, at (800) 447-1139.

     Once you are  authorized  to utilize the  telephone  redemption  option,  a
redemption  of Shares may be  requested  by calling  PFPC at (800)  447-1139 and
requesting  that the redemption  proceeds be mailed to the primary  registration
address or wired per the authorized  instructions.  If the telephone  redemption
option or the telephone exchange option (as described below) is authorized, PFPC
may act on  telephone  instructions  from any  person  representing  himself  or
herself to be a shareholder  and believed by PFPC to be genuine.  PFPC's records
of such instructions are binding and shareholders, not the Company or PFPC, bear
the risk of loss in the event of unauthorized  instructions  reasonably believed
by the Company or PFPC to be genuine.  PFPC will employ reasonable procedures to
confirm that  instructions  communicated are genuine and, if it does not, it may
be liable for any losses due to  unauthorized  or fraudulent  instructions.  The
procedures  employed  by PFPC  in  connection  with  transactions  initiated  by
telephone  include tape recording of telephone  instructions  and requiring some
form of personal  identification  prior to acting upon instructions  received by
telephone.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address  unless you have  designated in your  Application  that such
proceeds  are to be sent by wire  transfer  to a  specified  checking or savings
account.  If proceeds are to be sent by wire  transfer,  a telephone  redemption
request  received prior to the close of regular  trading on the NYSE will result
in redemption  proceeds  being wired to your bank account on the next day that a
wire transfer can be effected.  The minimum redemption for proceeds sent by wire
transfer is $2,500. There is no maximum for proceeds sent by wire transfer.  The
Company may modify this  redemption  service at any time or charge a service fee
upon prior notice to shareholders, although no fee is currently contemplated.

     DURING TIMES OF DRASTIC ECONOMIC OR MARKET  CONDITIONS,  YOU MAY EXPERIENCE
DIFFICULTY  IN  CONTACTING  BEAR  STEARNS,  THE  DISTRIBUTOR  OR YOUR  BROKER BY
TELEPHONE TO REQUEST A REDEMPTION OF SHARES.  IN SUCH CASES, YOU SHOULD CONSIDER
USING  THE OTHER  REDEMPTION  PROCEDURES  DESCRIBED  ABOVE.  USE OF THESE  OTHER
REDEMPTION  PROCEDURES MAY RESULT IN THE REDEMPTION REQUEST BEING PROCESSED AT A
LATER TIME THAN IT WOULD HAVE BEEN IF TELEPHONE REDEMPTION HAD BEEN USED.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $250; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     AUTOMATIC   WITHDRAWAL.   Automatic   withdrawal  permits  you  to  request
withdrawal of a specified  dollar amount (minimum of $25) on either a monthly or
quarterly basis if the investor has a $5,000 minimum account.  You can obtain an
application for automatic  withdrawal from Bear Stearns,  the Distributor,  your
broker, or the transfer agent.  Automatic withdrawal may be ended at any time by
either you, the Company or the  transfer  agent.  Shares for which  certificates
have been issued may not be redeemed through automatic withdrawal.  Purchases of
additional shares concurrently with withdrawals generally are undesirable.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form. However, if you bought your Shares by check, the Company
will  wait for your  check to clear  (up to 15  days)  before  it  accepts  your
redemption  request.  This procedure does not apply to Shares  purchased by wire
payment.  You should consider  purchasing Shares using a certified or bank check
or money order if you anticipate an immediate need for redemption proceeds.

                                       15

<PAGE>

     The Company  does not impose a charge when Shares are  redeemed,  except as
described  below.  The Company  reserves  the right to redeem any account in the
Bedford Class involuntarily, on thirty days' notice, if such account falls below
$500 and during such 30-day notice period the amount invested in such account is
not increased to at least $500.  Payment for Shares redeemed may be postponed or
the right of redemption suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lessor of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a fund.

EXCHANGE PRIVILEGE

     The exchange  privilege  enables you to purchase Bedford Shares in exchange
for shares of the other mutual funds  sponsored or advised by Bear  Stearns,  to
the extent such shares are  offered for sale in your state of  residence.  These
funds have different investment objectives than the fund. To use this privilege,
you should  consult your  account  executive at Bear  Stearns,  your  investment
dealers who have sales  agreements  with Bear  Stearns,  the  Distributor,  your
broker or the transfer  agent to  determine  if it is available  and whether any
conditions  are imposed on its use.  Currently,  exchanges may be made among the
following  portfolios (and such additional  portfolios which may be added in the
future):
         -    S&P STARS Portfolio
         -    Large Cap Value Portfolio
         -    Small Cap Value Portfolio
         -    The Insiders Select Fund
         -    International Equity Portfolio
         -    Focus List Portfolio
         -    Balanced Portfolio
     To effect an exchange of Shares, exchange instructions must be given to the
transfer agent in writing or by telephone. If you wish to make an exchange, send
a written  request to PFPC,  Attention:  The RBB Fund -- Money Market  Portfolio
(Bedford  Class),   P.O.  Box  8960,   Wilmington,   Delaware  19899.  You  will
automatically  be provided with telephone  exchange  privileges  when opening an
account,  unless you indicate otherwise on the account application.  If you hold
share certificates, you are not eligible to exchange shares of the fund by phone
because share  certificates  must accompany all exchange  requests.  To add this
feature to an existing  account that previously did not provide for this option,
a Telephone  Authorization Form must be filed with the transfer agent. This form
is available from the transfer agent. Once you have made this election,  you may
contact  the  transfer  agent by  telephone  at (800)  447-1139  to request  the
exchange.  See "Redemption of Shares--Redemption by Telephone" for a description
of the Company's telephone transaction procedures. During periods of substantial
economic or market change,  telephone exchanges may be difficult to complete and
shareholders  may have to submit  exchange  requests  to the  transfer  agent in
writing.

     If you do not currently own Bedford Shares or a fund whose shares are being
acquired, a new account will be established with the same registration, dividend
and capital gain options and the same dealer of record as the account from which
shares  are  exchanged,  unless  you  specify  otherwise  in  writing  with  all
signatures  guaranteed  as  described  above.  To  participate  in an  automatic
investment plan or establish automatic withdrawal for the new account,  however,
you must file a specific  written  request before the exchange can be processed.
The exchange  privilege  may be modified or terminated at any time, or from time
to time,  by the  Company  on 60 days'  notice  to  affected  portfolio  or fund
shareholders.

     Before  any  exchange,  you must  obtain  and  should  review a copy of the
current  prospectus  of the  portfolio  or fund into which the exchange is being
made.  Prospectuses  may be obtained  from Bear  Stearns.  Except in the case of
Personal  Retirement Plans, the Shares being exchanged must have a current value
of at least $250; furthermore,  when establishing a new account by exchange, the
shares  being  exchanged  must  have a value of at  least  the  minimum  initial
investment  required for the  portfolio or fund into which the exchange is being
made. If making an exchange to an existing account,  the dollar value must equal
or exceed the  applicable  minimum  for  subsequent  investments.  If any amount
remains in the investment  portfolio from which the exchange is being made, such
amount must not be below the minimum  account value required by the portfolio or
fund.
                                       16
<PAGE>

     Shares will be exchanged at the next  determined  public offering price. To
qualify for the exchange privilege, at the time of the exchange, you must notify
Bear Stearns, the Distributor, your investment dealer or the transfer agent. Any
such  qualification  is subject to confirmation of your holdings through a check
of  appropriate  records.  No fees  currently  are  charged  directly to you for
exchanges,  although the Company reserves the right, upon not less than 60 days'
written notice,  to charge a $5.00 fee in accordance  with rules  promulgated by
the SEC. The Company  reserves the right to reject any exchange request in whole
or in part.  The Exchange  Privilege  may be modified or  terminated at any time
upon notice to shareholders.

     The  exchange of shares of one  portfolio  or fund for shares of another is
treated  for  federal  income  tax  purposes  as a sale of the  shares  given in
exchange by the  shareholder  and,  therefore,  an  exchanging  shareholder  may
realize a taxable gain or loss.

REDIRECTED  DISTRIBUTION OPTION. The Redirected  Distribution Option enables you
to invest  automatically  dividends or dividends and capital gain distributions,
if any, paid by the fund in shares of another portfolio of the Company or a fund
advised or sponsored  by Bear  Stearns in which you invest.  Shares of the other
portfolio or fund will be purchased at the then current public  offering  price.
If you are  investing in a fund that  charges a sales load,  you may qualify for
share  prices  which do not  include  the sales load or which  reflect a reduced
sales load.

This  privilege is available  only for existing  accounts and may not be used to
open new accounts.  Minimum subsequent investments do not apply. The Company may
modify or terminate this privilege at any time or charge a service fee. However,
no such fee currently is contemplated.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and net realized capital gains, if any, of the fund to the fund's  shareholders.
All  distributions  are reinvested in the form of additional full and fractional
Shares of the Class unless a shareholder elects otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by the fund will be  declared  as a  dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the Money Market Portfolio will generally be taxable to
shareholders.   It  is  expected  that  all,  or  substantially  all,  of  these
distributions will consist of ordinary income. You will be subject to income tax
on these distributions regardless of whether they are paid in cash or reinvested
in additional  shares.  The one major  exception to these tax principles is that
distributions on shares held in an IRA (or other tax-qualified plan) will not be
currently taxable.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Bedford Shares of the Money Market  Portfolio are sold without a sales load
on a continuous basis by Provident Distributors,  Inc., whose principal business
address is at Four Falls Corporate Center, West Conshohocken, PA 19428.

     The Board of Directors of the Company approved and adopted the Distribution
Agreement and Plan of Distribution  for the Class (the "Plan")  pursuant to Rule
12b-1 under the 1940 Act. Under the Plan, the Distributor is entitled to receive
from the Class a distribution  fee, which is accrued daily and paid monthly,  of
up to .65% on an annualized  basis of the average daily net assets of the Class.
The actual amount of such  compensation  is agreed upon from time to time by the
Company's  Board  of  Directors  and the  Distributor.  Under  the  Distribution
Agreement,  the Distributor has agreed to accept  compensation  for its services
thereunder  and under the Plan in the  amount of .60% of the  average  daily net
assets of the Class on an annualized  basis in any year. The Distributor may, in
its  discretion,  voluntarily  waive from time to time all or any portion of its
distribution fee.

     Under  the  Distribution  Agreement  and  the  Plan,  the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and  services  provided  to  shareholders  of the  Class
serviced by such  financial  institutions.  The  Distributor  may also reimburse
broker/dealers  for other  expenses  incurred  in the  promotion  of the sale of
Bedford  Shares.  The  Distributor  and/or  broker/dealers  pay for the  cost of
printing   (excluding   typesetting)   and  mailing  to  prospective   investors
prospectuses  and other  materials  relating to the Class as well as for related
direct mail, advertising and promotional expenses.

     The Plan  obligates  the  Company,  during the  period it is in effect,  to
accrue and pay to the Distributor on behalf of the Class the fee agreed to under
the  Distribution  Agreement.  Payments under the Plan are not based on expenses
actually incurred by the Distributor,  and the payments may exceed  distribution
expenses actually incurred. Because these fees are paid out of the fund's assets
on an  on-going  basis,  over time  these  fees will  increase  the cost of your
investment and may cost you more than paying other types of sales charges.

INTRODUCTION TO THE RISK/RETURN SUMMARY
- --------------------------------------------------------------------------------

     This  Prospectus has been written to provide you with the  information  you
need  to  make  an  informed  decision  about  whether  to  invest  in the  Cash
Preservation Classes of The RBB Fund, Inc. (the "Company").

     The two classes of common stock (each a "Cash  Preservation  Class") of the
Company offered by this Prospectus  represent interests in the Cash Preservation
Classes of the Money Market Portfolio and the Municipal Money Market  Portfolio.
This Prospectus and the Statement of Additional Information  incorporated herein
relate solely to the Cash Preservation Classes of the Company.

     This Prospectus has been organized so that each Portfolio has its own short
section with important facts about that particular Portfolio.  Once you read the
short sections about the Portfolios  that interests you, read the sections about
Purchase  and  Redemption  of Shares  of the Cash  Preservation  Classes  ("Cash
Preservation Shares"). These sections apply to both of the Portfolios offered by
this Prospectus.

                              IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)  U.S.  dollar-denominated  obligations issued or supported by the credit
         of U.S. or foreign banks or savings  institutions  with total assets of
         more than $1 billion (including obligations of foreign branches of such
         banks).

     2)  High  quality   commercial  paper  and  other  obligations   issued  or
         guaranteed  (or otherwise  supported) by U.S. and foreign  corporations
         and  other  issuers  rated (at the time of  purchase)  A-2 or higher by
         Standard  and Poor's,  Prime-2 or higher by  Moody's,  D-2 or higher by
         Duff & Phelps,  F-2 or  higher  by Fitch or TBW-2 or higher by  Thomson
         BankWatch,  as well as high quality corporate bonds rated AA (or Aa) or
         higher at the time of purchase by those rating agencies.  These ratings
         must be provided by at least two rating  agencies or by the only rating
         agency providing a rating.

     3)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     4)  Asset-backed securities (including interests in pools of assets such as
         mortgages,   installment   purchase   obligations   and   credit   card
         receivables).

     5)  Securities  issued  or  guaranteed  by the  U.S.  Government  or by its
         agencies or authorities.

     6)  Dollar-denominated   securities   issued  or   guaranteed   by  foreign
         governments or their political subdivisions, agencies or authorities.

     7)  Securities issued or guaranteed by state or local governmental bodies.

     8)  Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                       6

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                       7

<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term performance for Cash Preservation Shares. The information shows
you how the  fund's  performance  has  varied  year by year  and  provides  some
indication  of the risks of investing in the fund.  The chart and the table both
assume   reinvestment  of  dividends  and   distributions.   As  with  all  such
investments,   past   performance  is  not  an  indication  of  future  results.
Performance  reflects  fee waivers in effect.  If fee waivers were not in place,
the fund's performance would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Cash  Preservation  Shares of the fund.  The table is based on expenses
for the most recent fiscal year.

================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.25% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  "Other  expenses"  for the current  fiscal year are expected to be less
         than the amounts  shown  above  because  certain of the fund's  service
         providers  are waiving a portion of their fees and/or  reimbursing  the
         fund for  certain  other  expenses.  As a result of these fee  waivers,
         "Other  expenses" of the fund are estimated to be 0.30%.  These waivers
         and  reimbursements  are  expected  to remain in effect for the current
         fiscal  year.  However,  they  are  voluntary  and can be  modified  or
         terminated at any time without the fund's consent.

     3.  As a result of the fee waivers and/or reimbursements set forth in notes
         1 and 2, the total annual fund  operating  expenses which are estimated
         to be incurred during the current fiscal year are 0.95%. Although these
         fee waivers and/or  reimbursements are expected to remain in effect for
         the current  fiscal year,  they are  voluntary and may be terminated at
         any time at the option of BIMC or the fund's service providers.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remains the same.  Although  your actual costs may be higher or lower,  based on
these assumptions your cost would be:

INVESTMENT GOAL

     The fund seeks to generate current income exempt from federal income taxes,
to provide you with liquidity and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve  this goal,  we invest in a  diversified  portfolio of Municipal
Securities. Specifically, we may invest in:

     1)  Fixed and variable  rate notes and similar debt  instruments  issued by
         issuers who have  ratings at the time of  purchase of MIG-2,  VMIG-2 or
         Prime-2  or higher by  Moody's,  SP-2 or A-2 or  higher by  Standard  &
         Poor's,  D-2 or higher by Duff & Phelps,  or F-2 or higher by Fitch (or
         guaranteed or otherwise supported by entities with such ratings).

     2)  Tax-exempt  commercial  paper and similar  debt  instruments  issued by
         issuers  who have  ratings at the time of purchase of Prime-2 or higher
         by Moody's, A-2 or higher by Standard & Poor's, D-2 or higher by Duff &
         Phelps, or F-2 or higher by Fitch (or guaranteed or otherwise supported
         by entities with such ratings).

     3)  Municipal  bonds  issued by  issuers  who have  ratings  at the time of
         purchase  of Aa or higher by  Moody's  or AA or  higher by  Standard  &
         Poor's, Duff & Phelps or Fitch (or guaranteed or otherwise supported by
         entities with such ratings).

     4)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     5)  Municipal  bonds and notes whose  principal  and interest  payments are
         guaranteed by the U.S. Government or one of its agencies or authorities
         or which otherwise depend on the credit of the United States.

     The fund seeks to maintain a net asset value of $1.00 per share.

     We normally  invest at least 80% of its net assets in Municipal  Securities
and other  instruments  whose  interest  is exempt  from  federal  income tax or
subject to the Federal Alternative Minimum Tax.

     The fund may hold  uninvested  cash  reserves  during  temporary  defensive
periods or, if in our opinion suitable  Municipal  Securities are not available.
The fund may hold all of its assets in uninvested cash reserves during temporary
defensive periods. Uninvested cash will not earn income.

     We  intend  to have no more  than  25% of its  total  assets  in  Municipal
Securities of issuers located in the same state.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain variable and floating rate  instruments)
will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Municipal  Securities  include revenue bonds,  general obligation bonds and
municipal lease obligations. Revenue bonds include private activity bonds, which
are not payable  from the general  revenues  of the  issuer.  Consequently,  the
credit  quality of private  activity  bonds is usually  directly  related to the
credit  standing of the corporate user of the facility  involved.  To the extent
that the fund's assets are invested in private  activity bonds, the fund will be
subject to the particular  risks  presented by the laws and economic  conditions
relating to such projects and bonds to a greater  extent than if its assets were
not so invested.  Moral  obligation bonds are normally issued by special purpose
public authorities. If the issuer of moral obligation bonds is unable to pay its
debts from current  revenues,  it may draw on a reserve fund the  restoration of
which is a moral but not a legal  obligation of the state or municipality  which
created  the  issuer.  Risk  exists  that a  municipality  will not honor  moral
obligation  bonds.  Municipal lease obligations are not guaranteed by the issuer
and are generally less liquid than other securities.

     There may be less  information  available  on the  financial  condition  of
issuers of Municipal  Securities  than for public  corporations.  The market for
municipal  bonds may be less liquid than for taxable  bonds.  This means that it
may be harder to buy and sell Municipal Securities, especially on short notice.

     The fund may invest in bonds whose  interest  may be subject to the Federal
Alternative  Minimum Tax. Interest received on these bonds by a taxpayer subject
to the Federal Alternative Minimum Tax is taxable.

     We may invest 25% or more of assets in Municipal  Securities whose interest
is paid solely from  revenues of similar  projects.  For  example,  the fund may
invest more than 25% of its assets in Municipal  Securities  related to water or
sewer  systems.  This type of  concentration  exposes  the fund to the legal and
economic risks relating to those projects.

     We  will  rely on  legal  opinions  of  counsel  to  issuers  of  Municipal
Securities  as to the  tax-free  status of  investments  and will not do our own
analysis regarding tax-free status.

     The fund may purchase variable and floating rate instruments. Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline.The  absence of an active market for these
securities  could make it difficult  to dispose of them if the issuer  defaults.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term performance for Cash Preservation Shares. The information shows
you how the  fund's  performance  has  varied  year by year  and  provides  some
indication  of the risks of investing in the fund.  The chart and the table both
assume   reinvestment  of  dividends  and   distributions.   As  with  all  such
investments,   past   performance  is  not  an  indication  of  future  results.
Performance  reflects  fee waivers in effect.  If fee waivers were not in place,
the fund's performance would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Cash  Preservation  Shares of the fund.  The table is based on expenses
for the most recent fiscal year.

================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.
================================================================================

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 .............................            0.35%

     Distribution and service (12b-1) fees .........            0.40%

     Other expenses 2 ..............................           11.05%
                                                               ------
TOTAL ANNUAL FUND OPERATING EXPENSES 3 .............           11.80%
                                                               ======

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are .09% of  average  daily  net  assets.  This  waiver  is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  "Other  expenses"  for the current  fiscal year are expected to be less
         than the amounts  shown  above  because  certain of the fund's  service
         providers  are waiving a portion of their fees and/or  reimbursing  the
         fund for  certain  other  expenses.  As a result of these fee  waivers,
         "Other  expenses" of the fund are estimated to be 0.49%.  These waivers
         and  reimbursements  are  expected  to remain in effect for the current
         fiscal  year.  However,  they  are  voluntary  and can be  modified  or
         terminated at any time without the fund's consent.

     3.  As a result of the fee waivers and/or reimbursements set forth in notes
         1 and 2, the total annual fund  operating  expenses which are estimated
         to be incurred during the current fiscal year are 0.98%. Although these
         fee waivers and/or  reimbursements are expected to remain in effect for
         the current  fiscal year,  they are  voluntary and may be terminated at
         any time at the option of BIMC or the fund's service providers.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                               1 YEAR       3 YEARS       5 YEARS      10 YEARS

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated  by dividing a fund's  total
assets, less its liabilities, by the number of shares outstanding.

     Each fund values its securities  using amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may  purchase  Cash  Preservation  Shares  by  mail,  wire or
exchange from another Cash  Preservation  Class as described  below. The minimum
initial  investment  is $1,000 and the  minimum  subsequent  investment  is $100
($1,000 if transmitted by wire).  The Company in its sole  discretion may accept
or reject any order for purchases of Cash Preservation Shares.

     If you hold Shares in the street name  account of a  broker/dealer  and you
want to transfer  your Shares to another  broker/dealer,  contact  your  current
broker/dealer.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES BY MAIL. You may also make direct  investments at any time in any
Cash  Preservation  Class you select  through any broker that has entered into a
dealer agreement with the Distributor (an "Authorized Dealer").  You may make an
initial  investment  in any of the Cash  Preservation  Classes  by mail by fully
completing  and signing an application  obtained from an Authorized  Dealer (the
"Application"),  specifying  the  Portfolio  in which  you wish to  invest,  and
mailing it,  together  with a check payable to "Cash  Preservation"  to the Cash
Preservation  Portfolios,  c/o PFPC, P.O. Box 8916, Wilmington,  Delaware 19899.
The check must  specify  the name of the  Portfolio  for which  shares are being
purchased. An Application will be returned to you unless it contains the name of
the  Authorized  Dealer from whom you obtained it.  Subsequent  purchases may be
made through an  Authorized  Dealer or by  forwarding  payment to the  Company's
transfer agent at the foregoing address.

                                       18

<PAGE>

     PURCHASES BY BANK WIRE. You may also purchase  Shares in either of the Cash
Preservation Classes by having your bank or Authorized Dealer wire Federal Funds
to the Company's Custodian,  PFPC Trust Company.  Your bank or Authorized Dealer
may impose a charge for this service.  The Company does not currently charge for
effecting wire transfers but reserves the right to do so in the future. In order
to ensure prompt receipt of your Federal Funds wire, for an initial  investment,
it is important that you follow these steps:

       A. Telephone the Company's transfer agent, PFPC, toll-free (800) 430-9618
          and provide your name, address,  telephone number,  Social Security or
          Tax Identification  Number, the Cash Preservation Class selected,  the
          amount being wired, and by which bank or Authorized Dealer.  PFPC will
          then  provide  you with an account  number.  (If you have an  existing
          account, you should also notify PFPC prior to wiring funds.)

       B. Instruct your bank or Authorized  Dealer to wire the specified amount,
          together with your assigned account number, to PFPC's account with PNC
          Bank:

          PNC Bank, N.A., Philadelphia, PA ABA-0310-0005-3.
          FROM: (your name)
          ACCOUNT NUMBER: (your account number with the Portfolio)
          FOR PURCHASE OF: (name of the Portfolio)
          AMOUNT: (amount to be invested)

       C. Fully  complete  and sign the  Application  and mail it to the address
          shown  thereon.  PFPC  will not  process  initial  purchases  until it
          receives a fully completed and signed Application. An Application will
          be  returned  to you  unless it  contains  the name of the  Authorized
          Dealer from whom you obtained it.

     For subsequent investments, you should follow steps A and B above.

     BY PAYMENT  FROM  INSURANCE  POLICIES.  If you are a  recipient  of certain
insurance policy payments,  you may purchase Shares by completing and signing an
Application,  including the section which  authorizes your insurance  company to
forward  policy  payments  to  the  Cash  Preservation  Class  indicated  on the
Application, and mailing it to PFPC at the address shown thereon. An Application
will be  returned to you unless it contains  the name of the  Authorized  Dealer
from whom you obtained it.

     AUTOMATIC INVESTMENT PLAN. Additional investments may be made automatically
by  authorizing  PFPC to  withdraw  funds  from your  bank  account  through  an
Automatic Investment Plan. If you wish to participate in an Automatic Investment
Plan, you should call PFPC at (800) 430-9618 to obtain the appropriate form.

     RETIREMENT PLANS. Cash Preservation  Shares may be purchased in conjunction
with individual  retirement accounts ("IRAs") and rollover IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or an Authorized Dealer. To determine whether the
benefits of an IRA are available  and/or  appropriate,  you should  consult with
your tax adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION  BY MAIL.  You may  redeem  any  number of  Shares by  sending a
written  request to the  Company's  transfer  agent,  PFPC Inc.,  P.O. Box 8916,
Wilmington, Delaware 19899, Attention: Cash Preservation Portfolios.  Redemption
requests must be signed by each shareholder in the same manner as the Shares are
registered.

                                       19

<PAGE>

Redemption  requests  for joint  accounts  require the  signature  of each joint
owner.  On  redemption  requests  of  $5,000  or more,  each  signature  must be
guaranteed.  A signature guarantee may be obtained from a domestic bank or trust
company,  broker,  dealer,  clearing  agency  or  savings  association  who  are
participants  in a  medallion  program  recognized  by the  Securities  Transfer
Association.  The three recognized  medallion  programs are Securities  Transfer
Agents Medallion Program (STAMP),  Stock Exchanges  Medallion Program (SEMP) and
New York Stock  Exchange,  Inc.  Medallion  Signature  Program (MSP).  Signature
guarantees that are not part of these programs will not be accepted.

     REDEMPTION BY TELEPHONE.  If you are a direct investor, you may redeem your
Shares without charge by telephone if you have completed and returned an account
application  containing the appropriate  telephone election.  To add a telephone
option to an existing  account that  previously did not provide for this option,
you must file a Telephone  Authorization  Form with PFPC. This form is available
from PFPC.  Once this  election  has been made,  you may simply  contact PFPC by
telephone  to request the  redemption  by calling  (800)  430-9618.  Neither the
Company,  the  Distributor,  the  Portfolios,  the  Administrator  nor any other
Company  agent  will be liable  for any loss,  liability,  cost or  expense  for
following the procedures  below or for following  instructions  communicated  by
telephone that they reasonably believe to be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and name of the portfolio,  all of which must match the
Company's  records;  (3)  requiring  the  Company's  service  representative  to
complete  a  telephone  transaction  form,  listing  all  of  the  above  caller
identification information;  (4) requiring that redemption proceeds be sent only
by check to the account  owners of record at the  address of record,  or by wire
only to the  owners of record  at the bank  account  of  record;  (5)  sending a
written  confirmation for each telephone  transaction to the owners of record at
the  address  of record  within  five (5)  business  days of the  call;  and (6)
maintaining  tapes of  telephone  transactions  for six  months,  if the Company
elects to record shareholder telephone transactions. For accounts held of record
by  broker-dealers  (other  than  the  Distributor),   financial   institutions,
securities  dealers,   financial  planners  or  other  industry   professionals,
additional  documentation  or  information  regarding  the scope of authority is
required.   Finally,  for  telephone  transactions  in  accounts  held  jointly,
additional  information  regarding other account holders is required.  Telephone
transactions  will not be permitted in connection  with IRA or other  retirement
plan accounts or by attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have designated in your  Application or Telephone
Authorization  Form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account  on the next day  that a wire  transfer  can be  effected.  The  minimum
redemption for proceeds sent by wire transfer is $1,000. There is no maximum for
proceeds sent by wire transfer.  The Company may modify this redemption  service
at any time or charge a service fee upon prior notice to shareholders,  although
no fee is currently contemplated.

     REDEMPTION BY CHECK.  You may request that the Company  provide  redemption
checks  drawn  on a  particular  Cash  Preservation  Class.  If you  hold  share
certificates,  you are not eligible  for this check  writing  privilege  because
share certificates must accompany all redemption  requests.  Checks will be sent
only to the registered owner(s) and only to the address of record. You may issue
checks  made  payable  to the order of any person in the amount of $100 or more.
The redemption is not effective  until the check is processed and cleared by the
transfer  agent,  and  dividends  are earned until the  redemption  is effected.
Because  dividends  accrue daily, you should not use a check to close an account
as a small  balance is likely to result.  There is no charge for  redemption  by
check. If you have check writing privileges and you exchange funds from one Cash
Preservation Class into another Cash Preservation  Class, you will automatically
receive  a  checkbook  for the new  account  (allow  three  to  four  weeks  for
delivery).  The Company or PNC Bank may terminate this redemption service at any
time, and neither shall incur any liability for honoring  checks,  for effecting
redemptions to pay checks, or for returning checks which have not been accepted.

                                       20

<PAGE>

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves  the  right  to  redeem  any  account  in  a  Cash  Preservation  Class
involuntarily,  on thirty days'  notice,  if such  account  falls below $500 and
during  such 30-day  notice  period the amount  invested in such  account is not
increased to at least $500.  Payment for Shares redeemed may be postponed or the
right of redemption suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a fund.

EXCHANGE PRIVILEGE

     If you wish to exchange Shares of one Cash  Preservation  Class for another
Cash  Preservation  Class,  you may do so by mail or by  telephone.  In order to
establish a  systematic  withdrawal  plan for the new  account,  you must file a
written  request.  The  Company and PFPC  reserve  the right to limit,  amend or
terminate  these exchange  privileges at any time upon 60 days written notice to
shareholders.  No exchange fee is currently imposed for exchanges;  however, the
Company  reserves the right to charge  shareholders an exchange fee of $5.00 for
each exchange.  If you hold share certificates,  the certificates must accompany
your  request for an  exchange.  An exchange of Shares will be treated as a sale
for federal tax purposes.

     Detailed Instructions Required. A request for an exchange of Shares must be
sufficiently detailed to enable PFPC to complete the exchange in accordance with
your wishes.  The request must name the Portfolio and account  number from which
the  exchange  is to be made.  It must  also  name the  Portfolio  to which  the
exchange is to be made and the account number,  if to an existing  account.  The
request must specify the amount of money or Shares to be exchanged. New accounts
will be established with the same  registration  and address,  and with the same
options as your account from which the exchange is made - an  Application is not
needed.  If the registration or address of the new account is to be different in
any respect,  the request must be in writing with all signatures  guaranteed.  A
signature  guarantee  may be  obtained  from a domestic  bank or trust  company,
broker, dealer,  clearing agency or savings associations who are participants in
a medallion program recognized by the Securities Transfer Association. The three
recognized  medallion  programs are the  Securities  Transfer  Agents  Medallion
Program  (STAMP),  Stock Exchanges  Medallion  Program (SEMP) and New York Stock
Exchange,  Inc. Medallion Signature Program (MSP). Signature guarantees that are
not part of these programs will not be accepted.

     To request an exchange by mail, send a written  request  (together with any
share certificates  issued to the investor) to: Cash Preservation c/o PFPC, P.O.
Box  8916,  Wilmington,  Delaware  19899.  The  request  must be  signed  by all
shareholders exactly as their names appear on the Company's records.

     If the  exchange is to a new account,  the dollar value of Shares  acquired
must  equal or  exceed  the  Portfolio's  minimum  for a new  account;  if to an
existing  account the dollar value must equal or exceed the Portfolio's  minimum
for subsequent investments. If any amount remains in the Cash Preservation Class
from which the  exchange  is being  made,  such  amount  must not drop below the
minimum account value required by that Portfolio.

                                       21

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and  net  realized   capital  gains,  if  any,  of  each  fund  to  each  fund's
shareholders.  All  distributions  are reinvested in the form of additional full
and  fractional  Shares  of  the  relevant  Cash  Preservation  Class  unless  a
shareholder elects otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by each fund will be  declared  as a dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the Money Market Portfolio will generally be taxable to
shareholders.   It  is  expected  that  all,  or  substantially  all,  of  these
distributions will consist of ordinary income. You will be subject to income tax
on these distributions regardless of whether they are paid in cash or reinvested
in additional  shares.  The one major  exception to these tax principles is that
distributions on shares held in an IRA (or other tax-qualified plan) will not be
currently taxable.

     Distributions  from the Municipal  Money Market  Portfolio  will  generally
constitute  tax-exempt  income for shareholders for federal income tax purposes.
It is possible,  depending upon the Portfolios'  investments,  that a portion of
each  Portfolio's  distributions  could be taxable to  shareholders  as ordinary
income or capital gains, but it is not expected that this will be the case.

     Interest on  indebtedness  incurred by a  shareholder  to purchase or carry
shares of the Municipal Money Market Portfolio  generally will not be deductible
for federal income tax purposes.

     You should note that a portion of the exempt-interest dividends paid by the
Municipal  Money Market  Portfolio may  constitute an item of tax preference for
purposes   of   determining   federal   alternative   minimum   tax   liability.
Exempt-interest  dividends  will also be  considered  along with other  adjusted
gross income in determining  whether any Social Security or railroad  retirement
payments received by you are subject to federal income taxes.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Cash  Preservation  Shares of the funds are sold  without a sales load on a
continuous  basis by Provident  Distributors,  Inc.,  whose  principal  business
address is at Four Falls Corporate Center, West Conshohocken, PA 19428.

     The Board of Directors of the Company approved and adopted the Distribution
Agreement  and  separate  Plans  of   Distribution   for  each  of  the  Classes
(collectively,  the  "Plans")  pursuant to Rule 12b-1 under the 1940 Act.  Under
each of the Plans, the Distributor is entitled to receive from the relevant Cash
Preservation  Class a distribution fee, which is accrued daily and paid monthly,
of up to .65% on an  annualized  basis of the  average  daily net  assets of the
relevant Cash  Preservation  Class.  The actual amount of such  compensation  is
agreed  upon  from  time to time by the  Company's  Board of  Directors  and the
Distributor.  Under the  Distribution  Agreement,  the Distributor has agreed to
accept  compensation  for its  services  thereunder  and  under the Plans in the
amount of .40% of the  average  daily net  assets  of the  relevant  Class on an
annualized   basis  in  any  year.  The  Distributor  may,  in  its  discretion,
voluntarily waive from time to time all or any portion of its distribution fee.

     Under the Distribution Agreement and the relevant Plan, the Distributor may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and services  provided to  shareholders  of any relevant
Class  serviced  by  such  financial  institutions.  The  Distributor  may  also
reimburse  broker/dealers  for other  expenses  incurred in the promotion of the
sale of Cash Preservation Shares. The Distributor and/or  broker/dealers pay for
the  cost  of  printing  (excluding  typesetting)  and  mailing  to  prospective
investors  prospectuses  and other materials  relating to the Cash  Preservation
Class as well as for related direct mail, advertising and promotional expenses.

     Each of the Plans obligates the Company, during the period it is in effect,
to accrue and pay to the Distributor on behalf of each Cash  Preservation  Class
the fee agreed to under the Distribution Agreement. Payments under the Plans are
not based on expenses actually incurred by the Distributor, and the payments may
exceed distribution expenses actually incurred.  Because these fees are paid out
of the funds'  assets on an on-going  basis,  over time these fees will increase
the cost of your  investment  and may cost you more than  paying  other types of
sales charges.

MONEY MARKET PORTFOLIO

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

================================================================================

     IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.

================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)   U.S. dollar-denominated obligations issued or supported by the credit
          of U.S. or foreign banks or savings institutions with total assets of
          more than $1 billion (including obligations of foreign branches of
          such banks).

     2)   High quality commercial paper and other obligations issued or
          guaranteed (or otherwise supported) by U.S. and foreign corporations
          and other issuers rated (at the time of purchase) A-2 or higher by
          Standard and Poor's, Prime-2 or higher by Moody's, D-2 or higher by
          Duff & Phelps, F-2 or higher by Fitch or TBW-2 or higher by Thomson
          BankWatch, as well as high quality corporate bonds rated AA (or Aa) or
          higher at the time of purchase by those rating agencies. These ratings
          must be provided by at least two rating agencies, or by the only
          rating agency providing a rating.

     3)   Unrated notes, paper and other instruments that are determined by us
          to be of comparable quality to the instruments described above.

     4)   Asset-backed securities (including interests in pools of assets such
          as mortgages, installment purchase obligations and credit card
          receivables).

     5)   Securities issued or guaranteed by the U.S. Government or by its
          agencies or authorities.

     6)   Dollar-denominated securities issued or guaranteed by foreign
          governments or their political subdivisions, agencies or authorities.

     7)   Securities issued or guaranteed by state or local governmental bodies.

     8)   Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                        6

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                        7

<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Janney Shares.  The information  shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

the fund.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Janney Shares of the fund.  The table is based on expenses for the most
recent fiscal year.

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 .........................................  0.36%

     Distribution and service (12b-1) fees .....................  0.60%

                                                                  -----

================================================================================

     IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

================================================================================


     *    The table does not reflect  charges or credits which  investors  might
          incur if they invest through a financial institution.


     1.   BIMC has voluntarily undertaken that a portion of its management fee
          will not be imposed on the fund during the current fiscal year ending
          August 31, 2000. As a result of the fee waiver, current management
          fees of the fund are 0.25% of average daily net assets. This waiver is
          expected to remain in effect for the current fiscal year. However, it
          is voluntary and can be modified or terminated at any time without the
          fund's consent.

     2.   "Other expenses" for the current fiscal year are expected to be less
          than the amounts shown above because certain of the fund's service
          providers are waiving a portion of their fees and/or reimbursing the
          fund for certain other expenses. As a result of these fee waivers,
          "Other expenses" of the fund are estimated to be 0.15%. These waivers
          and reimbursements are expected to remain in effect for the current
          fiscal year. However, they are voluntary and can be modified or
          terminated at any time without the fund's consent.

     3.   As a result of the fee waivers and/or reimbursements set forth in
          notes 1 and 2, the total annual fund operating expenses which are
          estimated to be incurred during the current fiscal year are 1.00%.
          Although these fee waivers and/or reimbursements are expected to
          remain in effect for the current fiscal year, they are voluntary and
          may be terminated at any time at the option of BIMC or the fund's
          service providers.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                          1 YEAR       3 YEARS       5 YEARS        10 YEARS
                          ------       -------       -------        --------
     JANNEY SHARES         $121          $378          $654          $1,443

MUNICIPAL MONEY MARKET PORTFOLIO

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

================================================================================

     IMPORTANT DEFINITIONS

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

GENERAL  OBLIGATION BONDS: Bonds which are secured by the issuer's pledge of its
full faith, credit and taxing power for the payment of principal and interest.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

MUNICIPAL  LEASE  OBLIGATIONS:  These provide  participation  in municipal lease
agreements and installment  purchase contracts,  but are not part of the general
obligations of the municipality.

MUNICIPAL SECURITY: A short-term obligation issued by or on behalf of states and
possessions  of the  United  States,  their  political  subdivisions  and  their
agencies and authorities.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REVENUE  BONDS:  Bonds which are secured only by the revenues  from a particular
facility or class of  facilities,  such as a water or sewer system,  or from the
proceeds of a special excise tax or other revenue source.

TAX-EXEMPT COMMERCIAL PAPER:  Short-term Municipal Securities with maturities of
1 to 270 days.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.

================================================================================


INVESTMENT GOAL

     PRIMARY INVESTMENT STRATEGIES

     To achieve  this goal,  we invest in a  diversified  portfolio of Municipal
Securities.

     Specifically, we may invest in:

     1)   Fixed and variable rate notes and similar debt  instruments  issued by
          issuers who have  ratings at the time of purchase of MIG-2,  VMIG-2 or
          Prime-2  or higher by  Moody's,  SP-2 or A-2 or higher by  Standard  &
          Poor's,  D-2 or higher by Duff & Phelps, or F-2 or higher by Fitch (or
          guaranteed or otherwise supported by entities with such ratings).

     2)   Tax-exempt  commercial  paper and similar debt  instruments  issued by
          issuers who have  ratings at the time of purchase of Prime-2 or higher
          by Moody's,  A-2 or higher by Standard & Poor's, D-2 or higher by Duff
          &  Phelps,  or F-2 or  higher by Fitch  (or  guaranteed  or  otherwise
          supported by entities with such ratings).

     3)   Municipal  bonds  issued by  issuers  who have  ratings at the time of
          purchase  of Aa or higher by  Moody's  or AA or higher by  Standard  &
          Poor's,  Duff & Phelps or Fitch (or guaranteed or otherwise  supported
          by entities with such ratings).

     4)   Unrated notes,  paper and other  instruments that are determined by us
          to be of comparable quality to the instruments described above.

     5)   Municipal  bonds and notes whose  principal and interest  payments are
          guaranteed  by  the  U.S.   Government  or  one  of  its  agencies  or
          authorities  or which  otherwise  depend on the  credit of the  United
          States.

     The fund seeks to maintain a net asset value of $1.00 per share.

     We normally  invest at least 80% of its net assets in Municipal  Securities
and other  instruments  whose  interest  is exempt  from  federal  income tax or
subject to the Federal Alternative Minimum Tax.

     The fund may hold  uninvested  cash  reserves  during  temporary  defensive
periods or, if in our opinion suitable  Municipal  Securities are not available.
The fund may hold all of its assets in uninvested cash reserves during temporary
defensive periods. Uninvested cash will not earn income.

     We  intend  to have no more  than  25% of its  total  assets  in  Municipal
Securities of issuers located in the same state.

                                       11

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain variable and floating rate  instruments)
will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Municipal  Securities  include revenue bonds,  general obligation bonds and
municipal lease obligations. Revenue bonds include private activity bonds, which
are not payable  from the general  revenues  of the  issuer.  Consequently,  the
credit  quality of private  activity  bonds is usually  directly  related to the
credit  standing of the corporate user of the facility  involved.  To the extent
that the fund's assets are invested in private  activity bonds, the fund will be
subject to the particular  risks  presented by the laws and economic  conditions
relating to such projects and bonds to a greater  extent than if its assets were
not so invested.  Moral  obligation bonds are normally issued by special purpose
public authorities. If the issuer of moral obligation bonds is unable to pay its
debts from current  revenues,  it may draw on a reserve fund the  restoration of
which is a moral but not a legal  obligation of the state or municipality  which
created  the  issuer.  Risk  exists  that a  municipality  will not honor  moral
obligation  bonds.  Municipal lease obligations are not guaranteed by the issuer
and are generally less liquid than other securities.

     There may be less  information  available  on the  financial  condition  of
issuers of Municipal  Securities  than for public  corporations.  The market for
municipal  bonds may be less liquid than for taxable  bonds.  This means that it
may be harder to buy and sell Municipal Securities, especially on short notice.

     The fund may invest in bonds whose  interest  may be subject to the Federal
Alternative  Minimum Tax. Interest received on these bonds by a taxpayer subject
to the Federal Alternative Minimum Tax is taxable.

     We may invest 25% or more of assets in Municipal  Securities whose interest
is paid solely from  revenues of similar  projects.  For  example,  the fund may
invest more than 25% of its assets in Municipal  Securities  related to water or
sewer  systems.  This type of  concentration  exposes  the fund to the legal and
economic risks relating to those projects.

     We  will  rely on  legal  opinions  of  counsel  to  issuers  of  Municipal
Securities  as to the  tax-free  status of  investments  and will not do our own
analysis regarding tax-free status.

     The fund may purchase variable and floating rate instruments. Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Janney Shares.  The information  shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Janney Shares of the fund.  The table is based on expenses for the most
recent fiscal year.

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 ........................................   0.35%

     Distribution and service (12b-1) fees ....................   0.60%

     Other expenses 2 .........................................   0.25%

================================================================================

     IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

================================================================================

     *    The table does not reflect  charges or credits which  investors  might
          incur if they invest through a financial institution.

     1.   BIMC has  voluntarily  undertaken that a portion of its management fee
          will not be imposed on the fund during the current  fiscal year ending
          August 31,  2000.  As a result of the fee waiver,  current  management
          fees of the fund are 0.08% of average daily net assets. This waiver is
          expected to remain in effect for the current fiscal year.  However, it
          is voluntary and can be modified or terminated at any time without the
          fund's consent.

     2.   "Other  expenses" for the current  fiscal year are expected to be less
          than the amounts  shown above  because  certain of the fund's  service
          providers are waiving a portion of their fees and/or  reimbursing  the
          fund for certain  other  expenses.  As a result of these fee  waivers,
          "Other expenses" of the fund are estimated to be 0.18%.  These waivers
          and  reimbursements  are  expected to remain in effect for the current
          fiscal  year.  However,  they are  voluntary  and can be  modified  or
          terminated at any time without the fund's consent.

     3.   As a result  of the fee  waivers  and/or  reimbursements  set forth in
          notes 1 and 2, the total  annual  fund  operating  expenses  which are
          estimated  to be incurred  during the  current  fiscal year are 0.86%.
          Although  these fee  waivers  and/or  reimbursements  are  expected to
          remain in effect for the current  fiscal year,  they are voluntary and
          may be  terminated  at any time at the  option  of BIMC or the  fund's
          service providers.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                     1 YEAR        3 YEARS       5 YEARS      10 YEARS
                    --------       -------      -------       --------

GOVERNMENT OBLIGATIONS MONEY MARKET PORTFOLIO

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

================================================================================

     IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.

================================================================================

INVESTMENT GOAL

     The fund seeks to generate current income to provide you with liquidity and
to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest  exclusively  in short-term  U.S.  Treasury
bills, notes and other obligations  issued or guaranteed by the U.S.  Government
or its agencies or instrumentalities and related repurchase agreements.

     The fund seeks to maintain a net asset value of $1.00 per share.

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
purchase securities if such securities or their issuers have (or such securities
are guaranteed or otherwise  supported by entities which have)  short-term  debt
ratings at the time of  purchase in the two highest  rating  categories  from at
least two national rating agencies,  or one such rating if the security is rated
by only one agency. The fund may also purchase unrated securities  determined by
us to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     SECURITIES LENDING

     The fund may lend some of its securities on a short-term  basis in order to
earn extra  income.  The fund will  receive  collateral  in cash or high quality
securities equal to the current value of the loaned securities. These loans will
be limited to 33 1/3% of the value of the fund's total assets.

                                       16

<PAGE>

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government gives no assurances that it will provide  financial  support if it is
not obligated to do so by law. Default in these issuers could negatively  impact
the fund.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments their value is dependent on the credit paying ability of the issuer.
If the issuer were unable to make interest payments or default, the value of the
securities  would decline.  The absence of an active market for these securities
could make it difficult to dispose of them if the issuer defaults.

     Securities  loans  involve  the  risk of a delay  in  receiving  additional
collateral if the value of the securities goes up while they are on loan.  There
is also the risk of delay in  recovering  the  loaned  securities  and of losing
rights to the  collateral if a borrower goes bankrupt.  Therefore,  the fund may
lose the  opportunity to sell securities at a desirable  price.  Additionally in
the event that a borrower  of  securities  would file for  bankruptcy  or become
insolvent, disposition of securities may be delayed pending court action.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Janney Shares.  The information  shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Janney Shares of the fund.  The table is based on expenses for the most
recent fiscal year.

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 .........................................  0.42%

     Distribution and service (12b-1) fees .....................  0.60%

     Other expenses 2 ..........................................  0.19%
                                                                  -----

================================================================================

     IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

================================================================================


     *    The table does not reflect  charges or credits which  investors  might
          incur if they invest through a financial institution.


     1.   BIMC has  voluntarily  undertaken that a portion of its management fee
          will not be imposed on the fund during the current  fiscal year ending
          August 31,  2000.  As a result of the fee waiver,  current  management
          fees of the fund are 0.26% of average daily net assets. This waiver is
          expected to remain in effect for the current fiscal year.  However, it
          is voluntary and can be modified or terminated at any time without the
          fund's consent.

     2.   "Other  expenses" for the current  fiscal year are expected to be less
          than the amounts  shown above  because  certain of the fund's  service
          providers are waiving a portion of their fees and/or  reimbursing  the
          fund for certain  other  expenses.  As a result of these fee  waivers,
          "Other expenses" of the fund are estimated to be 0.14%.  These waivers
          and  reimbursements  are  expected to remain in effect for the current
          fiscal  year.  However,  they are  voluntary  and can be  modified  or
          terminated at any time without the fund's consent.

     3.   As a result  of the fee  waivers  and/or  reimbursements  set forth in
          notes 1 and 2, the total  annual  fund  operating  expenses  which are
          estimated  to be incurred  during the  current  fiscal year are 1.00%.
          Although  these fee  waivers  and/or  reimbursements  are  expected to
          remain in effect for the current  fiscal year,  they are voluntary and
          may be  terminated  at any time at the  option  of BIMC or the  fund's
          service providers.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                          1 YEAR       3 YEARS        5 YEARS      10 YEARS
                          ------       -------        -------      ---------

INVESTMENT GOAL

     The fund seeks to generate  current  income exempt from  federal,  New York
State and New York City Personal income taxes, to provide you with liquidity and
to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve  this goal,  we invest  primarily  in  Municipal  Securities  of
issuers located in New York.

     Specifically, we may invest in:

     1)   Fixed and variable rate notes and similar debt  instruments  issued by
          issuers who have  ratings at the time of purchase of MIG-2,  VMIG-2 or
          Prime-2  or higher by  Moody's,  SP-2 or A-2 or higher by  Standard  &
          Poor's,  D-2 or higher by Duff & Phelps, or F-2 or higher by Fitch (or
          guaranteed or otherwise supported by entities with such ratings).

     2)   Tax-exempt  commercial  paper and similar debt  instruments  issued by
          issuers who have  ratings at the time of purchase of Prime-2 or higher
          by Moody's,  A-2 or higher by Standard & Poor's, D-2 or higher by Duff
          &  Phelps,  or F-2 or  higher by Fitch  (or  guaranteed  or  otherwise
          supported by entities with such ratings).

     3)   Municipal  bonds  rated or issued by issuers  who have  ratings at the
          time of  purchase  of Aa or  higher  by  Moody's  or AA or  higher  by
          Standard & Poor's,  Duff & Phelps or Fitch (or guaranteed or otherwise
          supported by entities with such ratings).

     4)   Unrated notes,  paper and other  instruments that are determined by us
          to be of comparable quality to the instruments described above.

     5)   Municipal  bonds and notes whose  principal and interest  payments are
          guaranteed  by  the  U.S.   Government  or  one  of  its  agencies  or
          authorities  or which  otherwise  depend on the  credit of the  United
          States.

     The fund seeks to maintain a net asset value of $1.00 per share.

     We normally  invest at least 80% of its net assets in Municipal  Securities
and other  instruments whose interest is exempt from regular federal income tax.
Up to 20% can be invested in securities which are subject to Federal Alternative
Minimum Tax.

     We  intend  normally  to invest  at least  65% of its  assets in  Municipal
Securities of issuers located in New York.

                                       21

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
purchase securities if such securities or their issuers have (or such securities
are guaranteed or otherwise  supported by entities which have)  short-term  debt
ratings at the time of  purchase in the two highest  rating  categories  from at
least two national rating agencies,  or one such rating if the security is rated
by only one agency.  The fund may also purchase  securities  determined to be of
comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those  securities which have or are deemed to have
remaining  maturities  of 397 days or less  (except  for  certain  variable  and
floating rate instruments and securities  collateralizing repurchase agreements)
will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     We  concentrate  its  investments  in securities of issuers  located in New
York. The fund is non-diversified under the Investment Company Act of 1940 (1940
Act).  This  raises  special  concerns  because the fund's  performance  is more
dependent  upon the  performance  of a smaller  number of securities and issuers
than in a diversified  portfolio.  Some issuers of New York Municipal Securities
have experienced  serious financial  difficulties in recent years. The change in
value of any one security may affect the overall  value of the fund more than it
would a diversified portfolio. In particular, changes in the economic conditions
and governmental policies of New York and its political  subdivisions could hurt
the value of the fund's shares.

     Municipal  Securities  include revenue bonds,  general obligation bonds and
municipal lease obligations. Revenue bonds include private activity bonds, which
are not payable  from the general  revenues  of the  issuer.  Consequently,  the
credit  quality of private  activity  bonds is usually  directly  related to the
credit standing of the corporate users of the facility  involved.  To the extent
that the fund's assets are invested in private  activity bonds, the fund will be
subject to the particular  risks  presented by the laws and economic  conditions
relating to such projects and bonds to a greater  extent than if its assets were
not so invested.  Moral  obligation bonds are normally issued by special purpose
public authorities. If the issuer of moral obligation bonds is unable to pay its
debts from current  revenues,  it may draw on a reserve fund the  restoration of
which is a moral but not a legal  obligation of the state or municipality  which
created  the  issuer.  Risk  exists  that a  municipality  will not honor  moral
obligation  bonds.  Municipal lease obligations are not guaranteed by the issuer
and are generally less liquid than other securities.

     There may be less  information  available  on the  financial  condition  of
issuers of Municipal  Securities  than for public  corporations.  The market for
municipal  bonds may be less liquid than for taxable  bonds.  This means that it
may be harder to buy and sell Municipal Securities, especially on short notice.

     We may invest  without  limit in bonds the interest on which may be subject
to the Federal Alternative Minimum Tax. Interest on these bonds that is received
by taxpayers subject to the Federal Alternative Minimum Tax is taxable.

     We may invest 25% or more of assets in Municipal  Securities whose interest
is paid solely from  revenues of similar  projects.  For  example,  the fund may
invest more than 25% of its assets in Municipal  Securities  related to water or
sewer  systems.  This type of  concentration  exposes  the fund to the legal and
economic risks relating to those projects.

     We  will  rely on  legal  opinions  of  counsel  to  issuers  of  Municipal
Securities  as to the  tax-free  status of  investments  and will not do our own
analysis regarding tax-free status.

                                       22

<PAGE>

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult for the fund to dispose of them if the issuer
defaults.

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems  providers and vendors  servicing the Portfolios
to determine  their systems'  ability to handle Year 2000 problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term  performance for Janney Shares.  The information  shows you how
the fund's  performance  has varied year by year and provides some indication of
the risks of  investing  in the  fund.  The  chart  and the  table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Janney Shares of the fund.  The table is based on expenses for the most
recent fiscal year.

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 .........................................  0.35%

     Distribution and service (12b-1) fees .....................  0.60%

     Other expenses 2 ..........................................  0.31%
                                                                  -----

================================================================================

     IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

================================================================================


     *    The table does not reflect  charges or credits which  investors  might
          incur if they invest through a financial institution.


     1.   BIMC has  voluntarily  undertaken that a portion of its management fee
          will not be imposed on the fund during the current  fiscal year ending
          August 31,  2000.  As a result of the fee waiver,  current  management
          fees of the fund are 0.00% of average daily net assets. This waiver is
          expected to remain in effect for the current fiscal year.  However, it
          is voluntary and can be modified or terminated at any time without the
          fund's consent.

     2.   "Other  expenses" for the current  fiscal year are expected to be less
          than the amounts  shown above  because  certain of the fund's  service
          providers are waiving a portion of their fees and/or  reimbursing  the
          fund for certain  other  expenses.  As a result of these fee  waivers,
          "Other expenses" of the fund are estimated to be 0.20%.  These waivers
          and  reimbursements  are  expected to remain in effect for the current
          fiscal  year.  However,  they are  voluntary  and can be  modified  or
          terminated at any time without the fund's consent.

     3.   As a result  of the fee  waivers  and/or  reimbursements  set forth in
          notes 1 and 2, the total  annual  fund  operating  expenses  which are
          estimated  to be incurred  during the  current  fiscal year are 0.80%.
          Although  these fee  waivers  and/or  reimbursements  are  expected to
          remain in effect for the current  fiscal year,  they are voluntary and
          may be  terminated  at any time at the  option  of BIMC or the  fund's
          service providers.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                             1 YEAR        3 YEARS       5 YEARS      10 YEARS
                             ------        -------       -------      --------

PORTFOLIO MANAGEMENT

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

INVESTMENT ADVISER

     BIMC, a  majority-owned  indirect  subsidiary of PNC Bank,  N.A.  serves as

SHAREHOLDER INFORMATION

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

PRICING SHARES

     The  price  of your  shares  is also  referred  to as the net  asset  value
("NAV").

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated  by dividing a fund's  total
assets, less its liabilities, by the number of shares outstanding.

     Each fund values its securities  using amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may purchase  Janney Shares through an account  maintained by
Janney  Montgomery  Scott  ("JMS")  (the  "Account").  The  Company  in its sole
discretion may accept or reject any order for purchases of Janney Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
from JMS and the Company's custodian has Federal Funds immediately  available to
it.  Prompt   transmission   of  the  order  to  the  transfer  agent  is  JMS's
responsibility.  In those cases where  payment is made by check,  Federal  Funds
will generally become available two Business Days after the check is received by
JMS.  A  "Business  Day" is any day that both the New York Stock  Exchange  (the
"NYSE") and the Federal  Reserve Bank of  Philadelphia  (the "FRB") are open. On
any Business Day,  orders which are accompanied by Federal Funds and received by
the Company by 12:00 noon Eastern Time,  and orders as to which payment has been
converted into Federal Funds by 12:00 noon Eastern Time,  will be executed as of
12:00 noon that Business Day.  Orders which are accompanied by Federal Funds and
received by PFPC after 12:00 noon Eastern Time but prior to the close of regular
trading on the NYSE (generally 4:00 p.m.  Eastern Time),  and orders as to which
payment has been  converted into Federal Funds after 12:00 noon Eastern Time but
prior to the close of regular  trading on the NYSE on any Business  Day, will be
executed as of the close of regular  trading on the NYSE on that  Business  Day,
but will not be entitled to receive  dividends  declared on such  Business  Day.
Orders which are  accompanied by Federal Funds and received by the Company as of
the close of regular trading on the NYSE or later and orders as to which payment
has been  converted to Federal  Funds as of the close of regular  trading on the
NYSE or later on a Business  Day will be processed as of 12:00 noon Eastern Time
on the following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
an Account with JMS through  procedures and requirements  established by JMS. In
such event,  beneficial  ownership of Janney  Shares will be recorded by JMS and
will be  reflected  in the Account  statements  provided to you by JMS.  JMS may
impose minimum investment Account  requirements.  Although JMS does not impose a
sales  charge for  purchases  of Janney  Shares,  depending on the terms of your
Account with JMS, JMS may charge to your Account fees for  automatic  investment
and other  services  provided to your Account.  Information  concerning  Account
requirements,  services and charges  should be obtained from JMS, and you should
read this Prospectus in conjunction with any information received from JMS.

     JMS may offer you the ability to purchase  Janney Shares under an automatic
purchase program (a "Purchase Program") established by it. If you participate in
a Purchase Program,  then you will have your "free-credit" cash balances in your
Account  automatically  invested in Shares of the Janney Class designated by you
as the  "Primary  Janney  Class" for your  Purchase  Program.  The  frequency of
investments and the minimum  investment  requirement  will be established by JMS
and the Company.  In addition,  JMS may require a minimum  amount of cash and/or
securities  to be  deposited  in your  Account to  participate  in its  Purchase
Program. The description of JMS's Purchase

                                       28

<PAGE>

Program should be read for details,  and any inquiries  concerning  your Account
under a Purchase  Program  should be  directed  to JMS.  As a  participant  in a
Purchase Program,  you may change the designation of the Primary Janney Class at
any time by so instructing JMS.

     If JMS makes special  arrangements under which orders for Janney Shares are
received  by PFPC prior to 12:00 noon  Eastern  Time,  and JMS  guarantees  that
payment for such Shares will be made in available Federal Funds to the Company's
custodian  prior to the close of  regular  trading  on the NYSE on the same day,
such  purchase  orders will be  effective  and Shares will be  purchased  at the
offering  price in effect as of 12:00 noon Eastern Time on the date the purchase
order is received by PFPC.  Otherwise,  if JMS has not made such an arrangement,
pricing of shares will occur as described above under "General".

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you  beneficially own Janney Shares
through an Account,  you may redeem  Janney Shares in your Account in accordance
with instructions and limitations  pertaining to your Account by contacting JMS.
If such notice is received by PFPC by 12:00 noon  Eastern  Time on any  Business
Day, the redemption will be effective as of 12:00 noon Eastern Time on that day.
It is the  responsibility  of JMS to transmit  redemption orders and credit your
account with  redemption  proceeds on a timely basis.  Payment of the redemption
proceeds will be made after 12:00 noon Eastern Time on the day the redemption is
effected,  provided  that the Company's  custodian is open for business.  If the
custodian is not open,  payment will be made on the next bank  business  day. If
the redemption  request is received  between 12:00 noon and the close of regular
trading on the NYSE on a Business  Day, the  redemption  will be effective as of
the close of regular  trading on the NYSE on such  Business Day and payment will
be made on the next  bank  business  day  following  receipt  of the  redemption
request. If all of your Shares are redeemed, all accrued but unpaid dividends on
those Shares will be paid with the redemption proceeds.

     JMS will also redeem each day a sufficient  number of Shares of the Primary
Janney Class to cover debit balances  created by transactions in your Account or
instructions  for cash  disbursements.  Shares  will be redeemed on the same day
that a transaction occurs that results in such a debit balance or charge.

     JMS reserves the right to waive or modify criteria for  participation in an
Account or to terminate participation in an Account for any reason.

     REDEMPTION  BY  CHECK.  The  Company  will  provide  to you forms of drafts
("checks")  payable  through PNC Bank.  These  checks may be made payable to the
order of anyone. If you wish to use this check writing redemption procedure, you
should complete specimen  signature cards (available from JMS), and forward them
to JMS.  JMS will  then  arrange  for the  checks  to be  honored  by PNC  Bank.
Investors  with joint  accounts  may elect to have checks  honored with a single
signature.  Check  redemptions  will be subject to PNC  Bank's  rules  governing
checks.  An investor  will be able to stop  payment on a check  redemption.  The
Company or PNC Bank may  terminate  this  redemption  service  at any time,  and
neither shall incur any liability for honoring checks, for effecting redemptions
to pay checks, or for returning checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

                                       29

<PAGE>

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has  cleared.  You  should  consider  purchasing  Shares  using a
certified or bank check or money order if you  anticipate an immediate  need for
redemption proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves  the right to redeem any account in a Janney  Class  involuntarily,  on
thirty days'  notice,  if such  account  falls below $500 and during such 30-day
notice  period the amount  invested in such account is not increased to at least
$500.  Payment for Shares  redeemed may be postponed or the right of  redemption
suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250.000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and  net  realized   capital  gains,  if  any,  of  each  fund  to  each  fund's
shareholders.  All  distributions  are reinvested in the form of additional full
and fractional  Shares of the relevant Janney Class unless a shareholder  elects
otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by each fund will be  declared  as a dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions   from  the  Money  Market   Portfolio  and  the   Government
Obligations Money Market Portfolio will generally be taxable to shareholders. It
is expected that all, or substantially all, of these  distributions will consist
of  ordinary  income.  You will be subject to income tax on these  distributions
regardless of whether they are paid in cash or reinvested in additional  shares.
The one major exception to these tax principles is that  distributions on shares
held in an IRA (or other tax-qualified plan) will not be currently taxable.

     Distributions  from the Municipal  Money Market  Portfolio  will  generally
constitute  tax-exempt  income for shareholders for federal income tax purposes.
It is possible,  depending upon the Portfolios'  investments,  that a portion of
each  Portfolio's  distributions  could be taxable to  shareholders  as ordinary
income or capital gains, but it is not expected that this will be the case.

     Interest on  indebtedness  incurred by a  shareholder  to purchase or carry
shares of the Municipal Money Market  Portfolio and the New York Municipal Money
Market  Portfolio  generally  will not be  deductible  for  federal  income  tax
purposes.

     You should note that a portion of the exempt-interest dividends paid by the
Municipal  Money  Market  Portfolio  and the New  York  Municipal  Money  Market
Portfolio may  constitute an item of tax  preference for purposes of determining
federal alternative minimum tax liability.  Exempt-interest  dividends will also
be considered along with other adjusted gross income in determining  whether any
Social Security or railroad  retirement  payments received by you are subject to
federal income taxes.

                                       30

<PAGE>

     It is anticipated that distributions from the New York Municipal Securities
will  generally be exempt from New York State and New York City personal  income
(but not corporate franchise) taxes.  Although  distributions from the Municipal
Money Market  Portfolio and the New York  Municipal  Money Market  Portfolio are
exempt for federal income tax purposes,  they will generally  constitute taxable
income  for state  and  local  income  tax  purposes  except  that,  subject  to
limitations that vary depending on the state,  distributions  from interest paid
by a state or municipal entity may be exempt from tax in that state.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Janney  Shares of the funds are sold  without a sales load on a  continuous
basis by Provident  Distributors,  Inc., whose principal  business address is at
Four Falls Corporate Center, West Conshohocken, PA 19428.

     The Board of Directors of the Company approved and adopted the Distribution
Agreement  and separate  Plans of  Distribution  for each of the Janney  Classes
(collectively,  the  "Plans")  pursuant to Rule 12b-1 under the 1940 Act.  Under
each of the Plans,  the  Distributor  is entitled to receive  from the  relevant
Janney Class a distribution fee, which is accrued daily and paid monthly,  of up
to .65% on an  annualized  basis of the average daily net assets of the relevant
Janney Class. The actual amount of such compensation is agreed upon from time to
time by the  Company's  Board  of  Directors  and  the  Distributor.  Under  the
Distribution  Agreement,  the Distributor has agreed to accept  compensation for
its services thereunder and under the Plans in the amount of .60% of the average
daily net assets of the relevant  Class on an annualized  basis in any year. The
Distributor may, in its discretion,  voluntarily  waive from time to time all or
any portion of its distribution fee.

     Under the Distribution Agreement and the relevant Plan, the Distributor may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and services  provided to  shareholders  of any relevant
Class  serviced  by  such  financial  institutions.  The  Distributor  may  also
reimburse  broker/dealers  for other  expenses  incurred in the promotion of the
sale of Janney Shares. The Distributor and/or broker/dealers pay for the cost of
printing   (excluding   typesetting)   and  mailing  to  prospective   investors
prospectuses  and other  materials  relating to the Janney  Class as well as for
related direct mail, advertising and promotional expenses.

     Each of the Plans obligates the Company, during the period it is in effect,
to accrue  and pay to the  Distributor  on behalf of each  Janney  Class the fee
agreed to under the  Distribution  Agreement.  Payments  under the Plans are not
based on expenses  actually  incurred by the  Distributor,  and the payments may
exceed distribution expenses actually incurred.  Because these fees are paid out
of the funds'  assets on an on-going  basis,  over time these fees will increase
the cost of your  investment  and may cost you more than  paying  other types of
sales charges.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                             IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)  U.S.  dollar-denominated  obligations issued or supported by the credit
         of U.S. or foreign banks or savings  institutions  with total assets of
         more than $1 billion (including obligations of foreign branches of such
         banks).

     2)  High  quality   commercial  paper  and  other  obligations   issued  or
         guaranteed  (or otherwise  supported) by U.S. and foreign  corporations
         and  other  issuers  rated (at the time of  purchase)  A-2 or higher by
         Standard  and Poor's,  Prime-2 or higher by  Moody's,  D-2 or higher by
         Duff & Phelps,  F-2 or  higher  by Fitch or TBW-2 or higher by  Thomson
         BankWatch,  as well as high quality corporate bonds rated AA (or Aa) or
         higher at the time of purchase by those rating agencies.  These ratings
         must be provided by at least two rating  agencies or by the only rating
         agency providing a rating.

     3)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     4)  Asset-backed securities (including interests in pools of assets such as
         mortgages,   installment   purchase   obligations   and   credit   card
         receivables).

     5)  Securities  issued  or  guaranteed  by the  U.S.  Government  or by its
         agencies or authorities.

     6)  Dollar-denominated   securities   issued  or   guaranteed   by  foreign
         governments or their political subdivisions, agencies or authorities.

     7)  Securities issued or guaranteed by state or local governmental bodies.

     8)  Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                       7

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems providers and vendors servicing the Portfolio to
determine  their  systems'  ability to handle  Year 2000  problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     EXPENSES AND FEES
     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Select Shares of the fund.  The table is based on expenses for the most
recent fiscal year.

================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.
================================================================================

ANNUAL FUND OPERATING EXPENSES*
(Expenses that are deducted from fund assets)

Management Fees 1. ..........................    0.36%
Other expenses 2 ............................    0.05%
                                                 ----
Total annual fund operating expenses 3 ......    0.41%
                                                 ====

*    The table does not reflect  charges or credits which  investors might incur
     if they invest through a financial institution.
1.   BIMC HAS  VOLUNTARILY  UNDERTAKEN THAT A PORTION OF ITS MANAGEMENT FEE WILL
     NOT BE IMPOSED ON THE FUND DURING THE CURRENT FISCAL YEAR ENDING AUGUST 31,
     2000. AS A RESULT OF THE FEE WAIVER,  CURRENT  MANAGEMENT  FEES OF THE FUND
     ARE 0.25% OF AVERAGE DAILY NET ASSETS. THIS WAIVER IS EXPECTED TO REMAIN IN
     EFFECT FOR THE CURRENT  FISCAL YEAR.  HOWEVER,  IT IS VOLUNTARY  AND CAN BE
     MODIFIED OR TERMINATED AT ANY TIME WITHOUT THE FUND'S CONSENT.
2.   "Other  expenses" for the current  fiscal year are expected to be less than
     the amounts shown above because certain of the fund's service providers are
     waiving a portion of their fees  and/or  reimbursing  the fund for  certain
     other expenses.  As a result of these fee waivers,  "Other expenses" of the
     fund are  estimated  to be 0.02%.  These  waivers  and  reimbursements  are
     expected to remain in effect for the current fiscal year. However, they are
     voluntary  and can be modified or terminated at any time without the fund's
     consent.
3.   As a result of the fee waivers and/or  reimbursements  set forth in notes 1
     and 2, the total annual fund  operating  expenses which are estimated to be
     incurred  during the  current  fiscal  year are 0.27%.  Although  these fee
     waivers  and/or  reimbursements  are  expected  to remain in effect for the
     current  fiscal year,  they are voluntary and may be terminated at any time
     at the option of BIMC or the fund's service providers.

     EXAMPLE:
     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these  assumptions  your cost  would be:

                              1 YEAR    3 YEARS   5 YEARS    10 YEARS
                              ------    -------   -------    --------

SHAREHOLDER INFORMATION

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated by dividing the fund's total
assets, less its liabilities, by the number of shares outstanding.

     The fund values its securities  using  amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL.  You may purchase  Shares  through an account  maintained  by your
brokerage firm (the "Account") and you may also purchase Shares directly by mail
or wire. The minimum initial  investment is $200 million.  The Company  reserves
the right to waive  this  minimum  investment  requirement.  There is no minimum
subsequent  investment.  The Company in its sole discretion may accept or reject
any order for purchases of Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
your Account with PNC Bank or its affiliates through procedures and requirements
established by PNC Bank or its affiliates.  In such event,  beneficial ownership
of Shares will be recorded by PNC Bank or its  affiliates  and will be reflected
in the Account  statements  provided to you by PNC Bank or its  affiliates.  PNC
Bank or its  affiliates  may impose  minimum  investment  Account  requirements.
Although PNC Bank or its  affiliates  do not impose a sales charge for purchases
of Shares,  depending on the terms of your Account,  PNC Bank or its  affiliates
may charge to your  Account fees for  automatic  investment  and other  services
provided to your Account. Information concerning Account requirements,  services
and charges should be obtained from PNC Bank or its  affiliates,  and you should
read this Prospectus in conjunction with any information  received from PNC Bank
or its affiliates.

     PNC Bank or its  affiliates  may offer you the ability to  purchase  Shares
under an automatic  purchase program (a "Purchase  Program")  established by PNC
Bank or its affiliates.  If you participate in a Purchase Program, you will have
your "free-credit" cash balances in your Account with PNC Bank or its affiliates
automatically invested in Select Shares.

                                       12

<PAGE>

The frequency of  investments  and the minimum  investment  requirement  will be
established by PNC Bank or its affiliates and the Company. In addition, PNC Bank
or its affiliates  may require a minimum amount of cash and/or  securities to be
deposited  in  your  Account  to  participate  in  its  Purchase  Program.   The
description of PNC Bank's or its affiliates' Purchase Program should be read for
details,  and any inquiries  concerning  your Account  under a Purchase  Program
should be directed to PNC Bank or its affiliates.

     If PNC Bank or its affiliates makes special arrangements under which orders
for Select  Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and
your broker  guarantees  that  payment for such Shares will be made in available
Federal Funds to the Company's  custodian  prior to the close of regular trading
on the NYSE on the same day, such  purchase  orders will be effective and Shares
will be purchased at the offering  price in effect as of 12:00 noon Eastern Time
on the date the purchase  order is received by PFPC.  Otherwise,  if PNC Bank or
its affiliate has not made such an arrangement,  pricing of shares will occur as
described above under "General."

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT.  If you  beneficially own Select Shares
through an Account,  you may redeem  Shares in your Account in  accordance  with
instructions  and limitations  pertaining to your Account by contacting PNC Bank
or its affiliates. If such notice is received by PFPC by 12:00 noon Eastern Time
on any Business Day, the  redemption  will be effective as of 12:00 noon Eastern
Time on that day.  Payment of the  redemption  proceeds will be made after 12:00
noon  Eastern Time on the day the  redemption  is  effected,  provided  that the
Company's custodian is open for business.  If the custodian is not open, payment
will be made on the  next  bank  business  day.  If the  redemption  request  is
received  between  12:00 noon and the close of regular  trading on the NYSE on a
Business  Day,  the  redemption  will be  effective  as of the close of  regular
trading on the NYSE on such  Business  Day and payment  will be made on the next
bank business day following  receipt of the redemption  request.  If all of your
Shares are  redeemed,  all accrued but unpaid  dividends on those Shares will be
paid with the redemption proceeds.

     PNC Bank or its  affiliates  also  redeem each day a  sufficient  number of
Shares to cover  debit  balances  created  by  transactions  in your  Account or
instructions  for cash  disbursements.  Shares  will be redeemed on the same day
that a transaction occurs that results in such a debit balance or charge.

     PNC Bank or its  affiliates  reserve the right to waive or modify  criteria
for participation in an Account or to terminate  participation in an Account for
any reason.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves the right to redeem any account in the Select Class  involuntarily,  on
thirty days'  notice,  if such account falls below $1,500 and during such 30-day
notice  period the amount  invested in such account is not increased to at least
$1,500.  Payment for Shares redeemed may be postponed or the right of redemption
suspended as provided by the rules of the SEC.

                                       13

<PAGE>

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of the fund.

     DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and net realized  capital gains,  if any, of the fund to each  shareholder.  All
distributions  are  reinvested  in the form of  additional  full and  fractional
Shares unless a shareholder elects otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by the fund will be  declared  as a  dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the fund will generally be taxable to shareholders.  It
is expected that all, or substantially all, of these  distributions will consist
of  ordinary  income.  You will be subject to income tax on these  distributions
regardless of whether they are paid in cash or reinvested in additional  shares.
The one major exception to these tax principles is that  distributions on shares
held in an IRA (or other tax-qualified plan) will not be currently taxable.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.
================================================================================

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)  U.S.  dollar-denominated  obligations issued or supported by the credit
         of U.S. or foreign banks or savings  institutions  with total assets of
         more than $1 billion (including obligations of foreign branches of such
         banks).

     2)  High  quality   commercial  paper  and  other  obligations   issued  or
         guaranteed  (or otherwise  supported) by U.S. and foreign  corporations
         and  other  issuers  rated (at the time of  purchase)  A-2 or higher by
         Standard  and Poor's,  Prime-2 or higher by  Moody's,  D-2 or higher by
         Duff & Phelps,  F-2 or  higher  by Fitch or TBW-2 or higher by  Thomson
         BankWatch,  as well as high quality corporate bonds rated AA (or Aa) or
         higher at the time of purchase by those rating agencies.  These ratings
         must be provided by at least two rating  agencies or by the only rating
         agency providing a rating.

     3)  Unrated notes, paper and other instruments that are determined by us to
         be of comparable quality to the instruments described above.

     4)  Asset-backed securities (including interests in pools of assets such as
         mortgages,   installment   purchase   obligations   and   credit   card
         receivables).

     5)  Securities  issued  or  guaranteed  by the  U.S.  Government  or by its
         agencies or authorities.

     6)  Dollar-denominated   securities   issued  or   guaranteed   by  foreign
         governments or their political subdivisions, agencies or authorities.

     7)  Securities issued or guaranteed by state or local governmental bodies.

     8)  Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                        6

<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your investment.

     The fund could lose money if a seller under a repurchase agreement defaults
or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                        7

<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems providers and vendors servicing the Portfolio to
determine  their  systems'  ability to handle  Year 2000  problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY

     RISK/RETURN INFORMATION

     The chart and table  below  give you a picture  of the  variability  of the
fund's long-term performance for Sansom Street Shares. The information shows you
how the fund's  performance has varied year by year and provides some indication
of the risks of  investing  in the fund.  The  chart and the table  both  assume
reinvestment of dividends and distributions.  As with all such investments, past
performance  is not an indication of future  results.  Performance  reflects fee
waivers in effect.  If fee  waivers  were not in place,  the fund's  performance
would be reduced.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold Sansom  Street  Shares of the fund.  The table is based on expenses for
the most recent fiscal year.

================================================================================
                              IMPORTANT DEFINITIONS

MANAGEMENT  FEES:  Fees  paid  to  the  investment  adviser  for  the  portfolio
management services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and maintenance.

     *   The table does not reflect  charges or credits  which  investors  might
         incur if they invest through a financial institution.

     1.  BIMC has  voluntarily  undertaken  that a portion of its management fee
         will not be imposed on the fund during the  current  fiscal year ending
         August 31, 2000. As a result of the fee waiver, current management fees
         of the fund are 0.25% of  average  daily  net  assets.  This  waiver is
         expected to remain in effect for the current fiscal year.  However,  it
         is voluntary  and can be modified or terminated at any time without the
         fund's consent.

     2.  "Other  expenses"  for the current  fiscal year are expected to be less
         than the amounts  shown  above  because  certain of the fund's  service
         providers  are waiving a portion of their fees and/or  reimbursing  the
         fund for  certain  other  expenses.  As a result of these fee  waivers,
         "Other  expenses" of the fund are estimated to be 0.19%.  These waivers
         and  reimbursements  are  expected  to remain in effect for the current
         fiscal  year.  However,  they  are  voluntary  and can be  modified  or
         terminated at any time without the fund's consent.

     3.  As a result of the fee waivers and/or reimbursements set forth in notes
         1 and 2, the total annual fund  operating  expenses which are estimated
         to be incurred during the current fiscal year are 0.49%. Although these
         fee waivers and/or  reimbursements are expected to remain in effect for
         the current  fiscal year,  they are  voluntary and may be terminated at
         any time at the option of BIMC or the fund's service providers.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                        1 YEAR       3 YEARS      5 YEARS      10 YEARS
                        ------       -------      -------      --------

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated  by dividing a fund's  total
assets, less its liabilities, by the number of shares outstanding.

     The fund values its securities  using  amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

PURCHASE OF SHARES

     GENERAL. Shares may be purchased through PNC Bank or its affiliates ("PNC")
acting on behalf of its customers,  including individuals,  trusts, partnerships
and  corporations  who  maintain  accounts  (such as  custody,  trust or  escrow
accounts)  with PNC and who have  authorized  PNC to invest in the Sansom Street
Class  on  a  customer's   behalf.   Shares  may  also  be  purchase  through  a
broker-dealer  that has  entered  into a  dealer  agreement  with the  Company's
Distributor (a "Dealer").  The minimum initial investment is $1,500. There is no
minimum subsequent investment.  The Company in its sole discretion may accept or
reject any order for purchases of Sansom Street Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES THROUGH AN ACCOUNT WITH PNC OR A DEALER.  Shares may be purchased
through your accounts at PNC or a Dealer  through  procedures  and  requirements
established by PNC or a Dealer. Confirmations of Share purchases and redemptions
will be sent to PNC or the Dealer.  Beneficial ownership of Sansom Street Shares
will be recorded by PNC or the Dealer and  reflected in your account  statements
provided by them. If you wish to purchase Sansom Street Shares, contact PNC or a
Dealer.

     PNC may also impose minimum  customer  account  requirements.  Although PNC
does not impose a sales charge for purchases of Sansom Street Shares,  depending
upon the  terms of your  account,  PNC may  charge  account  fees for  automatic
investment and other cash  management  services.  Information  concerning  these
minimum account  requirements,  services and any charges will be provided by PNC
before you authorize the initial purchase of Shares.  This Prospectus  should be
read in conjunction with any information you receive from PNC.

                                       13

<PAGE>

     DIRECT PURCHASES THROUGH A DEALER.  You may also make an initial investment
by mail by fully  completing and signing an  application  obtained from a Dealer
(an  "Application")  and mailing it,  together  with a check  payable to "Sansom
Street Money Market  Portfolio," c/o PFPC, P.O. Box 8950,  Wilmington,  Delaware
19899. An Application will be returned unless it contains the name of the Dealer
from whom it was obtained.  Subsequent purchases may be made through a Dealer or
by forwarding payment to the Company's transfer agent at the address above.

     Conflict of interest  restrictions may apply to an institution's receipt of
compensation  paid by the Company in connection with the investment of fiduciary
funds in Sansom Street Shares.  Institutions,  including  banks regulated by the
Comptroller  of the Currency and  investment  advisers and other money  managers
subject  to the  jurisdiction  of the  SEC,  the  Department  of  Labor or state
securities  commissions,  are  urged to  consult  their  legal  advisers  before
investing fiduciary funds in Sansom Street Shares.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer agent,  PFPC. It is the  responsibility  of PNC and Dealers to transmit
promptly to PFPC your redemption request.  If you hold share  certificates,  the
certificates must accompany the redemption  request.  You may redeem all or some
of your Shares in accordance with one of the procedures described below.

     REDEMPTION OF SHARES IN AN ACCOUNT AT PNC. If you  beneficially  own Shares
through an account at PNC, you may redeem  Sansom  Street  Shares in  accordance
with instructions and limitations  pertaining to your account. If the redemption
request is received by PFPC by 12:00 noon Eastern Time on any Business  Day, the
redemption will be effective as of 12:00 noon Eastern Time on that day.  Payment
for redemption  orders effected before 12:00 noon Eastern Time will be wired the
same day in Federal  Funds to your account at PNC,  provided  that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  Payment for  redemption  orders which are
received between 12:00 noon Eastern Time and the close of regular trading on the
NYSE on a  Business  Day will be wired in Federal  Funds to your  account on the
next bank business day following  receipt of the redemption  request.  No charge
for wiring  redemption  payments  is imposed by the  Company,  although  PNC may
charge your account for redemption services.

     REDEMPTION  OF  SHARES  IN  AN  ACCOUNT  FOR  NON-PNC  CUSTOMERS.   If  you
beneficially own Shares through an account at a Dealer, you may redeem Shares in
your account in accordance with  instructions and limitations  pertaining to the
account by  contacting  the Dealer.  If such notice is received by PFPC from the
broker by 12:00 noon Eastern Time on any Business  Day, the  redemption  will be
effective as of 12:00 noon Eastern Time on that day.  Payment of the  redemption
proceeds will be made after 12:00 noon Eastern Time on the day the redemption is
effected,  provided  that the Company's  custodian is open for business.  If the
custodian is not open,  payment will be made on the next bank  business  day. If
the redemption  request is received  between 12:00 noon and the close of regular
trading of the NYSE on a Business  Day, the  redemption  will be effective as of
the close of regular  trading of the NYSE on that  Business Day and payment will
be made on the next  bank  business  day  following  receipt  of the  redemption
request.  If all Shares are redeemed,  all accrued but unpaid dividends on those
Shares will be paid with the redemption proceeds.

     A Dealer may also  redeem  each day a  sufficient  number of your Shares to
cover debit balances created by transactions in your account or instructions for
cash  disbursements.  Shares will be redeemed on the same day that a transaction
occurs that results in such a debit-balance or charge.

     Each  Dealer   reserves   the  right  to  waive  or  modify   criteria  for
participation in an account or to terminate  participation in an account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem any number of Shares by sending a written request to "Sansom Street Money
Market Portfolio," c/o PFPC, P.O. Box 8950, Wilmington, Delaware 19899.

                                       14

<PAGE>

It is  recommended  that such request be sent by registered or certified mail if
share certificates accompany the request.  Redemption requests must be signed by
each  shareholder  in the same manner as the Shares are  registered.  Redemption
requests  for joint  accounts  require the  signature  of each joint  owner.  On
redemption  requests of $5,000 or more, a signature  guarantee  is  required.  A
signature  guarantee  may be  obtained  from a domestic  bank or trust  company,
broker, dealer, clearing agency or savings association who are participants in a
medallion program recognized by the Securities Transfer  Association.  The three
recognized  medallion programs are Securities  Transfer Agents Medallion Program
(STAMP),  Stock Exchanges  Medallion Program (SEMP) and New York Stock Exchange,
Inc. Medallion Signature Program (MSP).  Signature  guarantees that are not part
of these programs will not be accepted.

     If you are a direct  investor,  you may  redeem  Shares  without  charge by
telephone if you have completed and returned an account  application  containing
the appropriate  telephone  election.  To add a telephone  option to an existing
account that  previously did not provide for this option,  contact PFPC at (800)
430-9618.  Once this  election  has been made,  you may simply  contact  PFPC by
telephone  to  request a  redemption  by calling  (800)  430-9618.  Neither  the
Company, the Portfolios, the Distributor,  PFPC nor any other Company agent will
be liable for any loss, liability,  cost or expense for following the procedures
described  below or for following  instructions  communicated  by telephone that
they reasonably believe to be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and the name of the portfolio,  all of which must match
the Company's  records;  (3) requiring the Company's  service  representative to
complete  a  telephone  transaction  form,  listing  all  of  the  above  caller
identification information;  (4) requiring that redemption proceeds be sent only
by check to the account  owners of record at the  address of record,  or by wire
only to the  owners of record  at the bank  account  of  record;  (5)  sending a
written  confirmation for each telephone  transaction to the owners of record at
the  address  of record  within  five (5)  business  days of the  call;  and (6)
maintaining  tapes of  telephone  transactions  for six  months,  if the Company
elects to record shareholder telephone transactions. For accounts held of record
by  broker-dealers  (other  than  the  Distributor),   financial   institutions,
securities  dealers,   financial  planners  or  other  industry   professionals,
additional  documentation  or  information  regarding  the  scope of a  caller's
authority is required.  Finally,  for  telephone  transactions  in accounts held
jointly,  additional  information  regarding  other account holders is required.
Telephone  transactions  will not be permitted in  connection  with IRA or other
retirement plan accounts or by an attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have  designated in the  Application or telephone
authorization  form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account on the next bank business day. The minimum  redemption for proceeds sent
by wire  transfer  is $2,500.  There is no  maximum  for  proceeds  sent by wire
transfer. The Company may modify this redemption service at any time or charge a
service fee upon prior  notice to  shareholders,  although  no fee is  currently
contemplated.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your account,  the Company will provide forms of drafts
("checks")  payable  through PNC Bank.  These  checks may be made payable to the
order of anyone.  The minimum amount of a check is $100;  however,  a Dealer may
establish a higher  minimum.  If you wish to use this check  writing  redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and forward them to PFPC. PFPC will then arrange for the checks to be honored by
PNC Bank. If you own Shares  through an account,  you should contact your Dealer
for  signature  cards.  Investors  with joint  accounts may elect to have checks
honored with a single signature. Check redemptions will be subject to PNC Bank's
rules governing checks.  You will be able to stop payment on a check redemption.
The Company or PNC Bank may terminate this  redemption  service at any time, and
neither shall incur any liability for honoring checks, for effecting redemptions
to pay checks, or for returning checks which have not been accepted.

                                       15

<PAGE>

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue  receiving  dividends on those Shares  representing the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of redemption proceeds may be delayed for
a period of up to fifteen  days after their  purchase,  pending a  determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  Investors should consider  purchasing Shares using a certified or
bank check or money order if they  anticipate an immediate  need for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves   the  right  to  redeem  any  account  in  the  Sansom   Street  Class
involuntarily,  on thirty days'  notice,  if that  account  falls below $500 and
during that  thirty-day  notice period the amount invested in the account is not
increased to at least $500.  Payment for Shares redeemed may be postponed or the
right of redemption suspended as provided by the rules of the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250,000 or 1% of its net asset value  during
any 90-day period of any one shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and net realized capital gains, if any, of the fund to the fund's  shareholders.
All  distributions  are reinvested in the form of additional full and fractional
Shares  of  the  relevant  Sansom  Street  Class  unless  a  shareholder  elects
otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by the fund will be  declared  as a dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the Money Market Portfolio will generally be taxable to
shareholders.   It  is  expected  that  all,  or  substantially  all,  of  these
distributions will consist of ordinary income. You will be subject to income tax
on these distributions regardless of whether they are paid in cash or reinvested
in additional  shares.  The one major  exception to these tax principles is that
distributions on shares held in an IRA (or other tax-qualified plan) will not be
currently taxable.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS

     Sansom  Street  Shares  of the  fund  are sold  without  a sales  load on a
continuous  basis by Provident  Distributors,  Inc.,  whose  principal  business
address is at Four Falls Corporate Center, West Conshohocken, PA 19428.

     The Board of Directors of the Company approved and adopted the Distribution
Agreement  and separate  Plan of  Distribution  for the Sansom Street Class (the
"Plan")  pursuant  to Rule  12b-1  under  the 1940  Act.  Under  the  Plan,  the
Distributor  is entitled to receive from the Sansom Street Class a  distribution
fee,  which is accrued  daily and paid  monthly,  of up to .20% on an annualized
basis of the average  daily net assets of the Sansom  Street  Class.  The actual
amount of such  compensation  is agreed upon from time to time by the  Company's
Board of Directors and the Distributor.  Under the Distribution  Agreement,  the
Distributor has agreed to accept  compensation  for its services  thereunder and
under the Plan in the  amount  of .05% of the  average  daily net  assets of the
Class  on an  annualized  basis  in  any  year.  The  Distributor  may,  in  its
discretion,  voluntarily  waive  from  time to time  all or any  portion  of its
distribution fee.

     Under  the  Distribution  Agreement  and  the  Plan,  the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and  services  provided  to  shareholders  of the  Class
serviced by such  financial  institutions.  The  Distributor  may also reimburse
broker/dealers  for other  expenses  incurred  in the  promotion  of the sale of
Sansom Street Shares. The Distributor and/or  broker/dealers pay for the cost of
printing   (excluding   typesetting)   and  mailing  to  prospective   investors
prospectuses and other materials  relating to the Sansom Street Class as well as
for related direct mail, advertising and promotional expenses.

     The Plan  obligates  the  Company,  during the  period it is in effect,  to
accrue and pay to the  Distributor  on behalf of the Sansom Street Class the fee
agreed  to under the  Distribution  Agreement.  Payments  under the Plan are not
based on expenses  actually  incurred by the  Distributor,  and the payments may
exceed distribution expenses actually incurred.  Because these fees are paid out
of the fund's  assets on an on-going  basis,  over time these fees will increase
the cost of your  investment  and may cost you more than  paying  other types of
sales charges.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------


     IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.

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

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)   U.S. dollar-denominated  obligations issued or supported by the credit
          of U.S. or foreign banks or savings  institutions with total assets of
          more than $1 billion  (including  obligations  of foreign  branches of
          such banks).

     2)   High  quality   commercial  paper  and  other  obligations  issued  or
          guaranteed (or otherwise  supported) by U.S. and foreign  corporations
          and other  issuers  rated (at the time of  purchase)  A-2 or higher by
          Standard  and Poor's,  Prime-2 or higher by Moody's,  D-2 or higher by
          Duff & Phelps,  F-2 or  higher by Fitch or TBW-2 or higher by  Thomson
          BankWatch, as well as high quality corporate bonds rated AA (or Aa) or
          higher at the time of purchase by those rating agencies. These ratings
          must be provided by at least two rating agencies or by the only rating
          agency providing a rating.

     3)   Unrated notes,  paper and other  instruments that are determined by us
          to be of comparable quality to the instruments described above.

     4)   Asset-backed  securities  (including interests in pools of assets such
          as  mortgages,   installment  purchase  obligations  and  credit  card
          receivables).

     5)   Securities  issued  or  guaranteed  by the U.S.  Government  or by its
          agencies or authorities.

     6)   Dollar-denominated   securities   issued  or   guaranteed  by  foreign
          governments or their political subdivisions, agencies or authorities.

     7)   Securities issued or guaranteed by state or local governmental bodies.

     8)   Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                        6
<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your  investment.  The fund could lose money if a seller
under a repurchase agreement defaults or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                        7
<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems providers and vendors servicing the Portfolio to
determine  their  systems'  ability to handle  Year 2000  problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     1.   BIMC has  voluntarily  undertaken that a portion of its management fee
          will not be imposed on the fund during the current  fiscal year ending
          August 31,  2000.  As a result of the fee waiver,  current  management
          fees of the fund are 0.25% of average daily net assets. This waiver is
          expected to remain in effect for the current fiscal year.  However, it
          is voluntary and can be modified or terminated at any time without the
          fund's consent.

     2.   As a result of the fee  waiver  set forth in note 1, the total  annual
          fund operating  expenses which are estimated to be incurred during the
          current fiscal year are 0.77%. Although this fee waiver is expected to
          remain in effect for the current  fiscal year, it is voluntary and may
          be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                           1 YEAR      3 YEARS      5 YEARS     10 YEARS
                           ------      -------      -------     --------

     The table below sets forth certain  financial  information  for the periods
indicated,  including per share information results for a single fund share. The
term "Total Return"  indicates how much your investment  would have increased or
decreased  during this period of time and assumes that you have  reinvested  all
dividends and  distributions.  This information has been derived from the fund's
financial  statements  audited  by  PricewaterhouseCoopers  LLP,  the  Company's
independent accountants. This information should be read in conjunction with the
fund's  financial  statements  which,  together  with the report of  independent
accountants,  are included in the fund's annual report,  which is available upon

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated by dividing the fund's total
assets, less its liabilities, by the number of shares outstanding.

     The fund values its securities  using  amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

 PURCHASE OF SHARES

     GENERAL. You may purchase Principal Shares through an account maintained by
your brokerage firm (the "Account") and you may also purchase Shares directly by
mail or wire.  The  minimum  initial  investment  is  $25,000,  and the  minimum
subsequent  investment is $2,500.  The Company in its sole discretion may accept
or reject any order for purchases of Principal Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
an Account with your broker through  procedures and requirements  established by
your broker.  The minimum and  subsequent  investment  in Shares are set by your
broker. In such event, beneficial ownership of Principal Shares will be recorded
by your broker and will be reflected in the Account  statements  provided to you
by your broker. Your broker may impose minimum investment Account  requirements.
Even if your  broker  does not impose a sales  charge for  purchases  of Shares,
depending on the terms of your  Account with your broker,  the broker may charge
to your Account fees for automatic  investment  and other  services  provided to
your Account. Information concerning Account requirements,  services and charges
should be obtained  from your  broker,  and you should read this  Prospectus  in
conjunction with any information  received from your broker.  Shares are held in
the street name account of your broker and if you desire to transfer such shares
to the street name account of another  broker,  you should  contact your current
broker.

     A broker  with whom you  maintain  an Account  may offer you the ability to
purchase  Shares under an  automatic  purchase  program (a  "Purchase  Program")
established by a participating broker. If you participate in a Purchase Program,
then  you  will  have  your   "free-credit"   cash   balances  in  your  Account
automatically invested in Principal

                                       12
<PAGE>

Shares. The frequency of investments and the minimum investment requirement will
be  established  by the  broker and the  Company.  In  addition,  the broker may
require a minimum  amount of cash  and/or  securities  to be  deposited  in your
Account  to  participate  in  its  Purchase  Program.  The  description  of  the
particular  broker's  Purchase  Program  should  be read  for  details,  and any
inquiries concerning your Account under a Purchase Program should be directed to
your broker.

     If your broker makes special  arrangements under which orders for Principal
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees that payment for such Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase  order is received by PFPC.  Otherwise,  if the broker has not
made such an arrangement,  pricing of shares will occur as described above under
"General."

     DIRECT  PURCHASES.  You may also  make  direct  investments  at any time in
Shares  through  any broker that has entered  into a dealer  agreement  with the
Distributor  (a "Dealer").  You may make an initial  investment by mail by fully
completing and signing an application obtained from a Dealer (the "Application")
and mailing it,  together with a check payable to "The  Principal  Class" to The
Principal  Class,  c/o PFPC,  P.O.  Box 8950,  Wilmington,  Delaware  19899.  An
Application  will be returned  to you unless it contains  the name of the Dealer
from whom you obtained it. Subsequent  purchases may be made through a Dealer or
by forwarding payment to the Company's transfer agent at the foregoing address.

     Provided that your  investment  is at least  $5,000,  you may also purchase
Principal  Shares  by  having  your bank or  Dealer  wire  Federal  Funds to the
Company's Custodian, PFPC Trust Company. Your bank or Dealer may impose a charge
for this  service.  The Company does not  currently  charge for  effecting  wire
transfers  but  reserves  the right to do so in the  future.  In order to ensure
prompt  receipt of your Federal  Funds wire,  for an initial  investment,  it is
important that you follow these steps:

     A.   Telephone  the  Company's  transfer  agent,   PFPC,   toll-free  (800)
          430-9618,  and provide your name,  address,  telephone number,  Social
          Security or Tax Identification  Number, the amount being wired, and by
          which  bank or  Dealer.  PFPC will then  provide  you with an  account
          number. (If you have an existing account,  you should also notify PFPC
          prior to wiring funds.)

     B.   Instruct  your bank or Dealer to wire the specified  amount,  together
          with your assigned account number, to PFPC's account with PNC Bank.

          PNC Bank, N.A., Philadelphia, PA
          ABA-0310-0005-3.
          FROM: (your name)
          ACCOUNT NUMBER: (your account number)
          FOR PURCHASE OF: Principal Class Money Market Portfolio
          AMOUNT: (amount to be invested)

     C.   Fully  complete  and sign the  Application  and mail it to the address
          shown  thereon.  PFPC  will not  process  initial  purchases  until it
          receives a fully completed and signed Application.

     For subsequent investments, you should follow steps A and B above.

                                       13

     RETIREMENT  PLANS.  Principal  Shares may be purchased in conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

      REDEMPTION  OF SHARES IN AN ACCOUNT.  If you  beneficially  own  Principal
Shares  through an Account,  you may redeem Shares in your Account in accordance
with instructions and limitations  pertaining to your Account by contacting your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Your brokerage firm may also redeem each day a sufficient  number of Shares
to cover debit balances  created by transactions in your Account or instructions
for  cash  disbursements.  Shares  will  be  redeemed  on the  same  day  that a
transaction occurs that results in such a debit balance or charge.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem any number of Shares by sending a written request to THE PRINCIPAL CLASS,
c/o PFPC, P.O. Box 8950, Wilmington, Delaware 19899. Redemption requests must be
signed by each  shareholder  in the same  manner as the Shares  are  registered.
Redemption  requests  for joint  accounts  require the  signature  of each joint
owner.  On  redemption  requests  of  $5,000  or more,  each  signature  must be
guaranteed.  A signature guarantee may be obtained from a domestic bank or trust
company,  broker,  dealer,  clearing  agency  or  savings  association  who  are
participants  in a  medallion  program  recognized  by the  Securities  Transfer
Association.  The three recognized  medallion  programs are Securities  Transfer
Agents Medallion Program (STAMP),  Stock Exchanges  Medallion Program (SEMP) and
New York Stock  Exchange,  Inc.  Medallion  Signature  Program (MSP).  Signature
guarantees that are not part of these programs will not be accepted.

     If you are a direct investor,  you may redeem your Shares without charge by
telephone if you have completed and returned an account  application  containing
the appropriate  telephone  election.  To add a telephone  option to an existing
account  that  previously  did not  provide  for this  option,  you must  file a
Telephone  Authorization  Form with PFPC. This form is available from PFPC. Once
this election has been made, you may simply contact PFPC by telephone to request
the redemption by calling (800) 430-9618.  Neither the Company, the Distributor,
the Portfolio,  the Administrator nor any other Company agent will be liable for
any loss,  liability,  cost or expense for following the procedures below or for
following instructions communicated by telephone that they reasonably believe to
be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and name of the portfolio,  all of which must match the
Company's  records;  (3)  requiring  the  Company's  service  representative  to
complete  a  telephone  transaction  form,  listing  all  of  the  above  caller
identification

                                       14
<PAGE>

information; (4) requiring that redemption proceeds be sent only by check to the
account owners of record at the address of record, or by wire only to the owners
of record at the bank account of record; (5) sending a written  confirmation for
each  telephone  transaction  to the  owners of record at the  address of record
within  five  (5)  business  days of the  call;  and (6)  maintaining  tapes  of
telephone  transactions  for  six  months,  if  the  Company  elects  to  record
shareholder   telephone   transactions.   For   accounts   held  of   record  by
broker-dealers (other than the Distributor), financial institutions,  securities
dealers,   financial  planners  or  other  industry  professionals,   additional
documentation  or  information  regarding  the scope of  authority  is required.
Finally,  for  telephone  transactions  in  accounts  held  jointly,  additional
information regarding other account holders is required.  Telephone transactions
will not be permitted in connection  with IRA or other  retirement plan accounts
or by attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have designated in your  Application or Telephone
Authorization  Form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account  on the next day  that a wire  transfer  can be  effected.  The  minimum
redemption for proceeds sent by wire transfer is $5,000. There is no maximum for
proceeds sent by wire transfer.  The Company may modify this redemption  service
at any time or charge a service fee upon prior notice to shareholders,  although
no fee is currently contemplated.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $100; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves the right to redeem any account in the Principal  Class  involuntarily,
on thirty  days'  notice,  if such  account  falls below  $1,500 and during such
30-day notice period the amount  invested in such account is not increased to at
least  $1,500.  Payment for Shares  redeemed  may be  postponed  or the right of
redemption suspended as provided by the rules of the SEC.

                                       15
<PAGE>

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and net realized  capital gains,  if any, of the fund to each  shareholder.  All
distributions  are  reinvested  in the form of  additional  full and  fractional
Shares unless a shareholder elects otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by the fund will be  declared  as a  dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the fund will generally be taxable to shareholders.  It
is expected that all, or substantially all, of these  distributions will consist
of  ordinary  income.  You will be subject to income tax on these  distributions
regardless of whether they are paid in cash or reinvested in additional  shares.
The one major exception to these tax principles is that  distributions on shares
held in an IRA (or other tax-qualified plan) will not be currently taxable.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Principal  Shares are sold  without a sales load on a  continuous  basis by
Provident Distributors,  Inc., whose principal business address is at Four Falls
Corporate Center, West Conshohocken, PA 19428.

     The  Company's  Board of Directors of the Company  approved and adopted the
Distribution  Agreement  and a separate Plan of  Distribution  for the Principal
Class (the  "Plan")  pursuant to Rule 12b-1 under the 1940 Act.  Under the Plan,
the Distributor is entitled to receive from the Class a distribution  fee, which
is accrued daily and paid monthly,  of up to .40% on an annualized  basis of the
average daily net assets of the Class. The actual amount of such compensation is
agreed  upon  from  time to time by the  Company's  Board of  Directors  and the
Distributor.  Under the  Distribution  Agreement,  the Distributor has agreed to
accept compensation for its services thereunder and under the Plan in the amount
of .40% of the average daily net assets of the Class on an  annualized  basis in
any year. The Distributor may, in its discretion, voluntarily waive from time to
time all or any portion of its distribution fee.

     Under  the  Distribution  Agreement  and  the  Plan,  the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and  services  provided  to  shareholders  of the  Class
serviced by such  financial  institutions.  The  Distributor  may also reimburse
broker/dealers  for other  expenses  incurred  in the  promotion  of the sale of
Shares.  The  Distributor  and/or  broker/dealers  pay for the cost of  printing
(excluding  typesetting) and mailing to prospective  investors  prospectuses and
other  materials  relating to the Principal  Class as well as for related direct
mail, advertising and promotional expenses.

     The Plan  obligates  the  Company,  during the  period it is in effect,  to
accrue and pay to the Distributor on behalf of the Class the fee agreed to under
the  Distribution  Agreement.  Payments under the Plan are not based on expenses
actually incurred by the Distributor,  and the payments may exceed  distribution
expenses actually incurred. Because these fees are paid out of the fund's assets
on an  on-going  basis,  over time  these  fees will  increase  the cost of your
investment and may cost you more than paying other types of sales charges

"Principal Class"). This Prospectus and the Statement of Additional  Information
incorporated herein relate solely to the Principal Class.

MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------


     IMPORTANT DEFINITIONS

ASSET-BACKED  SECURITIES:  Debt  securities that are backed by a pool of assets,
usually loans such as installment sale contracts or credit card receivables.

COMMERCIAL PAPER:  Short-term  securities with maturities of 1 to 270 days which
are issued by banks, corporations and others.

DOLLAR  WEIGHTED  AVERAGE  MATURITY:  The  average  amount  of  time  until  the
organizations  that issued the debt securities in the fund's  portfolio must pay
off the principal  amount of the debt.  "Dollar  weighted"  means the larger the
dollar  value  of a debt  security  in the  fund,  the  more  weight  it gets in
calculating this average.

LIQUIDITY:  Liquidity  is the ability to easily  convert  investments  into cash
without losing a significant amount of money in the process.

NET ASSET VALUE (NAV):  The value of everything the fund owns,  minus everything
it owes, divided by the number of shares held by investors.

REPURCHASE AGREEMENT: A special type of a short-term investment.  A dealer sells
securities  to a fund and  agrees  to buy them  back  later at a set  price.  In
effect,  the dealer is borrowing  the fund's  money for a short time,  using the
securities as collateral.

VARIABLE OR FLOATING RATE  SECURITIES:  Securities  whose  interest rates adjust
automatically  after a certain  period of time and/or  whenever a  predetermined
standard interest rate changes.

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

INVESTMENT GOAL

     The fund seeks to generate  current  income,  to provide you with liquidity
and to protect your investment.

PRIMARY INVESTMENT STRATEGIES

     To achieve this goal, we invest in a  diversified  portfolio of short term,
high quality, U.S. dollar-denominated  instruments,  including government, bank,
commercial and other obligations.

     Specifically, we may invest in:

     1)   U.S. dollar-denominated  obligations issued or supported by the credit
          of U.S. or foreign banks or savings  institutions with total assets of
          more than $1 billion  (including  obligations  of foreign  branches of
          such banks).

     2)   High  quality   commercial  paper  and  other  obligations  issued  or
          guaranteed (or otherwise  supported) by U.S. and foreign  corporations
          and other  issuers  rated (at the time of  purchase)  A-2 or higher by
          Standard  and Poor's,  Prime-2 or higher by Moody's,  D-2 or higher by
          Duff & Phelps,  F-2 or  higher by Fitch or TBW-2 or higher by  Thomson
          BankWatch, as well as high quality corporate bonds rated AA (or Aa) or
          higher at the time of purchase by those rating agencies. These ratings
          must be provided by at least two rating agencies or by the only rating
          agency providing a rating.

     3)   Unrated notes,  paper and other  instruments that are determined by us
          to be of comparable quality to the instruments described above.

     4)   Asset-backed  securities  (including interests in pools of assets such
          as  mortgages,   installment  purchase  obligations  and  credit  card
          receivables).

     5)   Securities  issued  or  guaranteed  by the U.S.  Government  or by its
          agencies or authorities.

     6)   Dollar-denominated   securities   issued  or   guaranteed  by  foreign
          governments or their political subdivisions, agencies or authorities.

     7)   Securities issued or guaranteed by state or local governmental bodies.

     8)   Repurchase agreements relating to the above instruments.

     The fund seeks to maintain a net asset value of $1.00 per share.

                                        6
<PAGE>

     QUALITY

     Under guidelines  established by the Company's Board of Directors,  we will
only  purchase  securities  if such  securities  or their  issuers have (or such
securities  are  guaranteed  or  otherwise  supported  by  entities  which have)
short-term  debt  ratings  at the time of  purchase  in the two  highest  rating
categories from at least two national rating agencies, or one such rating if the
security  is rated by only  one  agency.  Securities  that are  unrated  must be
determined to be of comparable quality.

     MATURITY

     The  dollar-weighted  average  maturity of all the  investments of the fund
will be 90 days or less. Only those securities  which have remaining  maturities
of 397 days or less (except for certain  variable and floating rate  instruments
and securities collateralizing repurchase agreements) will be purchased.

     KEY RISKS

     The value of money market  investments  tends to fall when current interest
rates rise.  Money market  investments  are generally less sensitive to interest
rate changes than longer-term securities.

     The fund's securities may not earn as high a level of income as longer term
or  lower  quality  securities,  which  generally  have  greater  risk  and more
fluctuation in value.

     The fund's  concentration  of its investments in the banking industry could
increase risks.  The  profitability of banks depends largely on the availability
and cost of funds,  which can change depending upon economic  conditions.  Banks
are also exposed to losses if  borrowers  get into  financial  trouble and can't
repay their loans.

     The  obligations  of foreign  banks and other  foreign  issuers may involve
certain  risks in  addition  to  those of  domestic  issuers,  including  higher
transaction costs, less complete financial  information,  political and economic
instability, less stringent regulatory requirements and less market liquidity.

     Unrated notes,  paper and other instruments may be subject to the risk that
an issuer may default on its obligation to pay interest and repay principal.

     The obligations  issued or guaranteed by state or local  government  bodies
may be issued by entities in the same state and may have interest  which is paid
from revenues of similar projects. As a result, changes in economic, business or
political  conditions  relating to a  particular  state or types of projects may
impact the fund.

     Treasury  obligations  differ only in their interest rates,  maturities and
time of issuance. These differences could result in fluctuations in the value of
such  securities  depending  upon the  market.  Obligations  of U.S.  Government
agencies and authorities  are supported by varying  degrees of credit.  The U.S.
Government  gives no assurances  that it will provide  financial  support to its
agencies and  authorities  if it is not  obligated  by law to do so.  Default in
these issuers could negatively impact the fund.

     The fund's investment in asset-backed securities may be negatively impacted
by interest rate  fluctuations or when an issuer pays principal on an obligation
held by the fund earlier or later than  expected.  These events may affect their
value and the return on your  investment.  The fund could lose money if a seller
under a repurchase agreement defaults or declares bankruptcy.

     We may  purchase  variable  and floating  rate  instruments.  Like all debt
instruments,  their  value is  dependent  on the  credit  paying  ability of the
issuer.  If the issuer were  unable to make  interest  payments or default,  the
value of the securities would decline. The absence of an active market for these
securities could make it difficult to dispose of them if the issuer defaults.

                                        7
<PAGE>

     The fund, like any business,  could be affected if the computer  systems on
which it relies do not  properly  process  information  beginning  on January 1,
2000. While Year 2000 issues could have a negative effect on the fund, BIMC, the
fund's investment adviser, is currently working to avoid such problems.  BIMC is
also working with other systems providers and vendors servicing the Portfolio to
determine  their  systems'  ability to handle  Year 2000  problems.  There is no
guarantee, however, that systems will work properly on or after January 1, 2000.
Year 2000  problems may also hurt  issuers  whose  securities  the fund holds or
securities markets generally.

     ALTHOUGH  WE SEEK TO  PRESERVE  THE VALUE OF YOUR  INVESTMENT  AT $1.00 PER
SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND. WHEN YOU INVEST IN
THIS FUND YOU ARE NOT MAKING A BANK DEPOSIT.  YOUR  INVESTMENT IS NOT INSURED OR
GUARANTEED  BY THE  FEDERAL  DEPOSIT  INSURANCE  CORPORATION  OR BY ANY  BANK OR
GOVERNMENTAL AGENCY.

     EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual fund operating
expenses are paid out of fund assets and are reflected in the fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold  Principal  Shares of the fund.  The table is based on expenses for the
most recent fiscal year.

     ANNUAL FUND OPERATING EXPENSES*
     (Expenses that are deducted from fund assets)

     Management Fees 1 .......................................... 0.36%

     Distribution and service (12b-1) fees ...................... 0.40%

     Other expenses ............................................. 0.09%
                                                                  -----

     Total annual fund operating expenses 2 ..................... 0.85%
                                                                  =====

- --------------------------------------------------------------------------------
     IMPORTANT DEFINITIONS

MANAGEMENT  FEES: Fees paid to the investment  adviser for portfolio  management
services.

OTHER EXPENSES: Includes administration,  transfer agency, custody, professional
fees and registration fees.

DISTRIBUTION  AND  SERVICE  FEES:  Fees  that  are paid to the  Distributor  for
shareholder account service and
maintenance.
- --------------------------------------------------------------------------------

     *    The table does not reflect  charges or credits which  investors  might
          incur if they invest through a financial institution.


     1.   BIMC has  voluntarily  undertaken that a portion of its management fee
          will not be imposed on the fund during the current  fiscal year ending
          August 31,  2000.  As a result of the fee waiver,  current  management
          fees of the fund are 0.25% of average daily net assets. This waiver is
          expected to remain in effect for the current fiscal year.  However, it
          is voluntary and can be modified or terminated at any time without the
          fund's consent.

     2.   As a result of the fee  waiver  set forth in note 1, the total  annual
          fund operating  expenses which are estimated to be incurred during the
          current fiscal year are 0.77%. Although this fee waiver is expected to
          remain in effect for the current  fiscal year, it is voluntary and may
          be terminated at any time at the option of BIMC.

     EXAMPLE:

     The example is intended  to help you compare the cost of  investing  in the
fund with the cost of investing in other mutual funds.  The example assumes that
you invest  $10,000 in the fund for the time periods  indicated  and then redeem
all of your shares at the end of each period. The example also assumes that your
investment  has a 5% return  each year and that the  fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your cost would be:

                           1 YEAR      3 YEARS      5 YEARS     10 YEARS
                           ------      -------      -------     --------

FINANCIAL HIGHLIGHTS

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

     The table below sets forth certain  financial  information  for the periods
indicated,  including per share information results for a single fund share. The
term "Total Return"  indicates how much your investment  would have increased or
decreased  during this period of time and assumes that you have  reinvested  all
dividends and  distributions.  This information has been derived from the fund's
financial  statements  audited  by  PricewaterhouseCoopers  LLP,  the  Company's
independent accountants. This information should be read in conjunction with the
fund's  financial  statements  which,  together  with the report of  independent
accountants,  are included in the fund's annual report,  which is available upon
request (see back cover for ordering instructions).

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING SHARES

     The price of your shares is also referred to as the net asset value (NAV).

     The NAV is determined  twice daily at 12:00 noon and at 4:00 p.m.,  Eastern
Time, each day on which both the New York Stock Exchange and the Federal Reserve
Bank of  Philadelphia  are open.  It is  calculated by dividing the fund's total
assets, less its liabilities, by the number of shares outstanding.

     The fund values its securities  using  amortized cost. This method values a
fund holding  initially at its cost and then assumes a constant  amortization to
maturity of any  discount  or premium.  The  amortized  cost method  ignores any
impact of changing interest rates.

 PURCHASE OF SHARES

     GENERAL. You may purchase Principal Shares through an account maintained by
your brokerage firm (the "Account") and you may also purchase Shares directly by
mail or wire.  The  minimum  initial  investment  is  $25,000,  and the  minimum
subsequent  investment is $2,500.  The Company in its sole discretion may accept
or reject any order for purchases of Principal Shares.

     Purchases  will be effected at the net asset  value next  determined  after
PFPC, the Company's  transfer agent, has received a purchase order in good order
and the Company's  custodian has Federal Funds  immediately  available to it. In
those cases where payment is made by check,  Federal Funds will generally become
available two Business Days after the check is received. A "Business Day" is any
day that both the New York Stock  Exchange (the "NYSE") and the Federal  Reserve
Bank of Philadelphia (the "FRB") are open. On any Business Day, orders which are
accompanied  by Federal  Funds and received by the Company by 12:00 noon Eastern
Time,  and orders as to which payment has been  converted  into Federal Funds by
12:00 noon Eastern  Time,  will be executed as of 12:00 noon that  Business Day.
Orders which are  accompanied  by Federal Funds and received by PFPC after 12:00
noon  Eastern  Time  but  prior  to the  close of  regular  trading  on the NYSE
(generally  4:00 p.m.  Eastern  Time),  and orders as to which  payment has been
converted  into  Federal  Funds after 12:00 noon  Eastern  Time but prior to the
close of regular trading on the NYSE on any Business Day, will be executed as of
the close of regular  trading on the NYSE on that  Business Day, but will not be
entitled to receive  dividends  declared on such Business Day.  Orders which are
accompanied  by Federal  Funds and  received  by the  Company as of the close of
regular  trading on the NYSE or later,  and orders as to which  payment has been
converted  to Federal  Funds as of the close of  regular  trading on the NYSE or
later on a Business  Day will be  processed as of 12:00 noon Eastern Time on the
following Business Day.

     PURCHASES  THROUGH AN ACCOUNT.  Purchases of Shares may be effected through
an Account with your broker through  procedures and requirements  established by
your broker.  The minimum and  subsequent  investment  in Shares are set by your
broker. In such event, beneficial ownership of Principal Shares will be recorded
by your broker and will be reflected in the Account  statements  provided to you
by your broker. Your broker may impose minimum investment Account  requirements.
Even if your  broker  does not impose a sales  charge for  purchases  of Shares,
depending on the terms of your  Account with your broker,  the broker may charge
to your Account fees for automatic  investment  and other  services  provided to
your Account. Information concerning Account requirements,  services and charges
should be obtained  from your  broker,  and you should read this  Prospectus  in
conjunction with any information  received from your broker.  Shares are held in
the street name account of your broker and if you desire to transfer such shares
to the street name account of another  broker,  you should  contact your current
broker.

     A broker  with whom you  maintain  an Account  may offer you the ability to
purchase  Shares under an  automatic  purchase  program (a  "Purchase  Program")
established by a participating broker. If you participate in a Purchase Program,
then  you  will  have  your   "free-credit"   cash   balances  in  your  Account
automatically invested in Principal

                                       12
<PAGE>

Shares. The frequency of investments and the minimum investment requirement will
be  established  by the  broker and the  Company.  In  addition,  the broker may
require a minimum  amount of cash  and/or  securities  to be  deposited  in your
Account  to  participate  in  its  Purchase  Program.  The  description  of  the
particular  broker's  Purchase  Program  should  be read  for  details,  and any
inquiries concerning your Account under a Purchase Program should be directed to
your broker.

     If your broker makes special  arrangements under which orders for Principal
Shares are  received by PFPC prior to 12:00 noon Eastern  Time,  and your broker
guarantees that payment for such Shares will be made in available  Federal Funds
to the Company's  custodian prior to the close of regular trading on the NYSE on
the same  day,  such  purchase  orders  will be  effective  and  Shares  will be
purchased at the  offering  price in effect as of 12:00 noon Eastern Time on the
date the purchase  order is received by PFPC.  Otherwise,  if the broker has not
made such an arrangement,  pricing of shares will occur as described above under
"General."

     DIRECT  PURCHASES.  You may also  make  direct  investments  at any time in
Shares  through  any broker that has entered  into a dealer  agreement  with the
Distributor  (a "Dealer").  You may make an initial  investment by mail by fully
completing and signing an application obtained from a Dealer (the "Application")
and mailing it,  together with a check payable to "The  Principal  Class" to The
Principal  Class,  c/o PFPC,  P.O.  Box 8950,  Wilmington,  Delaware  19899.  An
Application  will be returned  to you unless it contains  the name of the Dealer
from whom you obtained it. Subsequent  purchases may be made through a Dealer or
by forwarding payment to the Company's transfer agent at the foregoing address.

     Provided that your  investment  is at least  $5,000,  you may also purchase
Principal  Shares  by  having  your bank or  Dealer  wire  Federal  Funds to the
Company's Custodian, PFPC Trust Company. Your bank or Dealer may impose a charge
for this  service.  The Company does not  currently  charge for  effecting  wire
transfers  but  reserves  the right to do so in the  future.  In order to ensure
prompt  receipt of your Federal  Funds wire,  for an initial  investment,  it is
important that you follow these steps:

     A.   Telephone  the  Company's  transfer  agent,   PFPC,   toll-free  (800)
          430-9618,  and provide your name,  address,  telephone number,  Social
          Security or Tax Identification  Number, the amount being wired, and by
          which  bank or  Dealer.  PFPC will then  provide  you with an  account
          number. (If you have an existing account,  you should also notify PFPC
          prior to wiring funds.)

     B.   Instruct  your bank or Dealer to wire the specified  amount,  together
          with your assigned account number, to PFPC's account with PNC Bank.

          PNC Bank, N.A., Philadelphia, PA
          ABA-0310-0005-3.
          FROM: (your name)
          ACCOUNT NUMBER: (your account number)
          FOR PURCHASE OF: Principal Class Money Market Portfolio
          AMOUNT: (amount to be invested)

     C.   Fully  complete  and sign the  Application  and mail it to the address
          shown  thereon.  PFPC  will not  process  initial  purchases  until it
          receives a fully completed and signed Application.

     For subsequent investments, you should follow steps A and B above.

                                       13

     RETIREMENT  PLANS.  Principal  Shares may be purchased in conjunction  with
individual  retirement  accounts  ("IRAs")  and  rollover  IRAs where PFPC Trust
Company acts as custodian. For further information as to applications and annual
fees,  contact the Distributor or your broker. To determine whether the benefits
of an IRA are available  and/or  appropriate,  you should  consult with your tax
adviser.

REDEMPTION OF SHARES

     GENERAL.  Redemption  orders are  effected at the net asset value per share
next  determined  after  receipt  of the order in proper  form by the  Company's
transfer  agent,  PFPC.  You may redeem all or some of your Shares in accordance
with one of the procedures described below.

      REDEMPTION  OF SHARES IN AN ACCOUNT.  If you  beneficially  own  Principal
Shares  through an Account,  you may redeem Shares in your Account in accordance
with instructions and limitations  pertaining to your Account by contacting your
broker.  If such notice is received  by PFPC by 12:00 noon  Eastern  Time on any
Business Day, the redemption  will be effective as of 12:00 noon Eastern Time on
that day.  Payment of the  redemption  proceeds  will be made  after  12:00 noon
Eastern Time on the day the redemption is effected,  provided that the Company's
custodian is open for business.  If the  custodian is not open,  payment will be
made on the next bank  business  day.  If the  redemption  request  is  received
between  12:00 noon and the close of  regular  trading on the NYSE on a Business
Day, the redemption  will be effective as of the close of regular trading on the
NYSE on such Business Day and payment will be made on the next bank business day
following receipt of the redemption request. If all of your Shares are redeemed,
all  accrued  but  unpaid  dividends  on  those  Shares  will be paid  with  the
redemption proceeds.

     Your brokerage firm may also redeem each day a sufficient  number of Shares
to cover debit balances  created by transactions in your Account or instructions
for  cash  disbursements.  Shares  will  be  redeemed  on the  same  day  that a
transaction occurs that results in such a debit balance or charge.

     Each  brokerage  firm  reserves  the right to waive or modify  criteria for
participation in an Account or to terminate  participation in an Account for any
reason.

     REDEMPTION OF SHARES OWNED DIRECTLY.  If you own Shares  directly,  you may
redeem any number of Shares by sending a written request to THE PRINCIPAL CLASS,
c/o PFPC, P.O. Box 8950, Wilmington, Delaware 19899. Redemption requests must be
signed by each  shareholder  in the same  manner as the Shares  are  registered.
Redemption  requests  for joint  accounts  require the  signature  of each joint
owner.  On  redemption  requests  of  $5,000  or more,  each  signature  must be
guaranteed.  A signature guarantee may be obtained from a domestic bank or trust
company,  broker,  dealer,  clearing  agency  or  savings  association  who  are
participants  in a  medallion  program  recognized  by the  Securities  Transfer
Association.  The three recognized  medallion  programs are Securities  Transfer
Agents Medallion Program (STAMP),  Stock Exchanges  Medallion Program (SEMP) and
New York Stock  Exchange,  Inc.  Medallion  Signature  Program (MSP).  Signature
guarantees that are not part of these programs will not be accepted.

     If you are a direct investor,  you may redeem your Shares without charge by
telephone if you have completed and returned an account  application  containing
the appropriate  telephone  election.  To add a telephone  option to an existing
account  that  previously  did not  provide  for this  option,  you must  file a
Telephone  Authorization  Form with PFPC. This form is available from PFPC. Once
this election has been made, you may simply contact PFPC by telephone to request
the redemption by calling (800) 430-9618.  Neither the Company, the Distributor,
the Portfolio,  the Administrator nor any other Company agent will be liable for
any loss,  liability,  cost or expense for following the procedures below or for
following instructions communicated by telephone that they reasonably believe to
be genuine.

     The  Company's  telephone  transaction  procedures  include  the  following
measures:  (1) requiring the appropriate  telephone transaction privilege forms;
(2) requiring the caller to provide the names of the account owners, the account
social  security  number and name of the portfolio,  all of which must match the
Company's  records;  (3)  requiring  the  Company's  service  representative  to
complete  a  telephone  transaction  form,  listing  all  of  the  above  caller
identification

                                       14
<PAGE>

information; (4) requiring that redemption proceeds be sent only by check to the
account owners of record at the address of record, or by wire only to the owners
of record at the bank account of record; (5) sending a written  confirmation for
each  telephone  transaction  to the  owners of record at the  address of record
within  five  (5)  business  days of the  call;  and (6)  maintaining  tapes  of
telephone  transactions  for  six  months,  if  the  Company  elects  to  record
shareholder   telephone   transactions.   For   accounts   held  of   record  by
broker-dealers (other than the Distributor), financial institutions,  securities
dealers,   financial  planners  or  other  industry  professionals,   additional
documentation  or  information  regarding  the scope of  authority  is required.
Finally,  for  telephone  transactions  in  accounts  held  jointly,  additional
information regarding other account holders is required.  Telephone transactions
will not be permitted in connection  with IRA or other  retirement plan accounts
or by attorney-in-fact under power of attorney.

     Proceeds of a telephone  redemption request will be mailed by check to your
registered  address unless you have designated in your  Application or Telephone
Authorization  Form  that such  proceeds  are to be sent by wire  transfer  to a
specified  checking  or  savings  account.  If  proceeds  are to be sent by wire
transfer,  a telephone redemption request received prior to the close of regular
trading on the NYSE will result in redemption  proceeds being wired to your bank
account  on the next day  that a wire  transfer  can be  effected.  The  minimum
redemption for proceeds sent by wire transfer is $5,000. There is no maximum for
proceeds sent by wire transfer.  The Company may modify this redemption  service
at any time or charge a service fee upon prior notice to shareholders,  although
no fee is currently contemplated.

     REDEMPTION BY CHECK.  If you are a direct investor or you do not have check
writing  privileges  for your Account,  the Company will provide to you forms of
drafts ("checks")  payable through PNC Bank. These checks may be made payable to
the order of anyone. The minimum amount of a check is $100; however, your broker
may establish a higher minimum. If you wish to use this check writing redemption
procedure,  you should complete specimen  signature cards (available from PFPC),
and then forward such  signature  cards to PFPC.  PFPC will then arrange for the
checks to be honored  by PNC Bank.  If you own Shares  through an  Account,  you
should  contact your broker for signature  cards.  Investors with joint accounts
may elect to have checks honored with a single signature. Check redemptions will
be subject to PNC Bank's rules  governing  checks.  An investor  will be able to
stop payment on a check  redemption.  The Company or PNC Bank may terminate this
redemption  service at any time,  and  neither  shall  incur any  liability  for
honoring  checks,  for  effecting  redemptions  to pay checks,  or for returning
checks which have not been accepted.

     When a check is  presented  to PNC Bank for  clearance,  PNC Bank,  as your
agent,  will cause the  Company to redeem a  sufficient  number of your full and
fractional  Shares to cover the amount of the check.  This procedure enables you
to continue to receive  dividends on your Shares  representing  the amount being
redeemed  by check  until  such  time as the  check is  presented  to PNC  Bank.
Pursuant  to rules  under the 1940 Act,  checks  may not be  presented  for cash
payment at the offices of PNC Bank.  This limitation does not affect checks used
for the payment of bills or cash at other banks.

     ADDITIONAL REDEMPTION INFORMATION. The Company ordinarily will make payment
for all Shares  redeemed within seven days after receipt by PFPC of a redemption
request in proper form.  Although the Company  will redeem  Shares  purchased by
check before the check clears, payment of the redemption proceeds may be delayed
for a period of up to fifteen days after their purchase, pending a determination
that the check has cleared. This procedure does not apply to Shares purchased by
wire payment.  You should consider  purchasing  Shares using a certified or bank
check or  money  order  if you  anticipate  an  immediate  need  for  redemption
proceeds.

     The Company does not impose a charge when Shares are redeemed.  The Company
reserves the right to redeem any account in the Principal  Class  involuntarily,
on thirty  days'  notice,  if such  account  falls below  $1,500 and during such
30-day notice period the amount  invested in such account is not increased to at
least  $1,500.  Payment for Shares  redeemed  may be  postponed  or the right of
redemption suspended as provided by the rules of the SEC.

                                       15
<PAGE>

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a fund.

DIVIDENDS AND DISTRIBUTIONS

     The Company will distribute  substantially all of the net investment income
and net realized  capital gains,  if any, of the fund to each  shareholder.  All
distributions  are  reinvested  in the form of  additional  full and  fractional
Shares unless a shareholder elects otherwise.

     The net investment income (not including any net short-term  capital gains)
earned by the fund will be  declared  as a  dividend  on a daily  basis and paid
monthly.  Dividends are payable to shareholders of record  immediately  prior to
the  determination  of net asset  value  made as of the close of  trading of the
NYSE.  Net  short-term  capital  gains,  if any,  will be  distributed  at least
annually.

TAXES

     Distributions  from the fund will generally be taxable to shareholders.  It
is expected that all, or substantially all, of these  distributions will consist
of  ordinary  income.  You will be subject to income tax on these  distributions
regardless of whether they are paid in cash or reinvested in additional  shares.
The one major exception to these tax principles is that  distributions on shares
held in an IRA (or other tax-qualified plan) will not be currently taxable.

     The  foregoing  is only a summary of certain tax  considerations  under the
current law, which may be subject to change in the future.  Shareholders who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships  may be subject  to  different  United  States  Federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

DISTRIBUTION ARRANGEMENTS
- --------------------------------------------------------------------------------

     Principal  Shares are sold  without a sales load on a  continuous  basis by
Provident Distributors,  Inc., whose principal business address is at Four Falls
Corporate Center, West Conshohocken, PA 19428.

     The  Company's  Board of Directors of the Company  approved and adopted the
Distribution  Agreement  and a separate Plan of  Distribution  for the Principal
Class (the  "Plan")  pursuant to Rule 12b-1 under the 1940 Act.  Under the Plan,
the Distributor is entitled to receive from the Class a distribution  fee, which
is accrued daily and paid monthly,  of up to .40% on an annualized  basis of the
average daily net assets of the Class. The actual amount of such compensation is
agreed  upon  from  time to time by the  Company's  Board of  Directors  and the
Distributor.  Under the  Distribution  Agreement,  the Distributor has agreed to
accept compensation for its services thereunder and under the Plan in the amount
of .40% of the average daily net assets of the Class on an  annualized  basis in
any year. The Distributor may, in its discretion, voluntarily waive from time to
time all or any portion of its distribution fee.

     Under  the  Distribution  Agreement  and  the  Plan,  the  Distributor  may
reallocate  an  amount  up to  the  full  fee  that  it  receives  to  financial
institutions,  including  broker/dealers,  based upon the  aggregate  investment
amounts  maintained  by and  services  provided  to  shareholders  of the  Class
serviced by such  financial  institutions.  The  Distributor  may also reimburse
broker/dealers  for other  expenses  incurred  in the  promotion  of the sale of
Shares.  The  Distributor  and/or  broker/dealers  pay for the cost of  printing
(excluding  typesetting) and mailing to prospective  investors  prospectuses and
other  materials  relating to the Principal  Class as well as for related direct
mail, advertising and promotional expenses.

     The Plan  obligates  the  Company,  during the  period it is in effect,  to
accrue and pay to the Distributor on behalf of the Class the fee agreed to under
the  Distribution  Agreement.  Payments under the Plan are not based on expenses
actually incurred by the Distributor,  and the payments may exceed  distribution
expenses actually incurred. Because these fees are paid out of the fund's assets
on an  on-going  basis,  over time  these  fees will  increase  the cost of your
investment and may cost you more than paying other types of sales charges

BOSTON PARTNERS LARGE CAP VALUE FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

EQUITY SECURITY: A security, such as a stock, representing ownership of a
company. Bonds, in comparison, are referred to as fixed-income or debt
securities because they represent indebtedness to the bondholder, not ownership.

MARKET CAPITALIZATION: Market capitalization refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

VALUE  CHARACTERISTICS:  Stocks are  generally  divided into the  categories  of
"growth" or "value." Value stocks appear to the Adviser to be undervalued by the
market as measured by certain  financial  formulas.  Growth stocks appear to the
Adviser to have  earnings  growth  potential  that is greater than the market in
general,  and whose  growth in revenue is expected  to continue  for an extended
period of time.

EARNINGS GROWTH:  The increased rate of growth in a company's earnings per share
from period to period.  Security  analysts  attempt to identify  companies  with
earnings growth potential  because a pattern of earnings growth generally causes
share prices to increase.
================================================================================

INVESTMENT GOALS

     The Fund seeks to provide  long-term  growth of capital with current income
as a secondary objective.

PRIMARY INVESTMENT STRATEGIES

     The Fund invests  (during  normal  market  conditions)  at least 65% of its
total  assets  in  a  diversified   portfolio  consisting  primarily  of  equity
securities, such as common stocks and securities convertible into common stocks,
of issuers with a market  capitalization of $1 billion or greater and identified
by Boston Partners Asset  Management  L.P. (the  "Adviser") as possessing  value
characteristics.  The Fund may also  invest  up to 20% of its  total  assets  in
non-U.S. dollar denominated securities.

     The   Adviser   examines   various   factors  in   determining   the  value
characteristics  of such issuers  including price to book value ratios and price
to earnings ratios.  These value  characteristics are examined in the context of
the issuer's  operating and financial  fundamentals such as return on equity and
earnings growth and cash flow. The Adviser selects securities for the Fund based
on a continuous study of trends in industries and companies,  earnings power and
growth and other investment criteria.

     In general, the Fund's investments are broadly diversified over a number of
industries  and, as a matter of policy,  the Fund will not invest 25% or more of
its total assets in any one industry.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the policies  above,  the Fund reserves the right to hold up to
100% of its assets, as a temporary  defensive measure, in cash and eligible U.S.
dollar-denominated  money market  instruments.  The Adviser will  determine when
market conditions warrant temporary defensive measures.


KEY RISKS

     (BULLET) At least 65% of the Fund's  total  assets  will be  invested  in a
       diversified  portfolio  of equity  securities,  and the net  asset  value
       ("NAV") of the Fund will change with  changes in the market  value of its
       portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) Although the Fund will invest in stocks the Adviser believes to be
       undervalued,  there is no guarantee  that the prices of these stocks will
       not move even lower.

     (BULLET) Convertible securities frequently have speculative characteristics
       and  may  be  acquired   without  regard  to  minimum  quality   ratings.
       Convertible  securities  and  obligations  rated in the lowest of the top
       four rating  categories  are subject to greater  credit and interest rate
       risk than higher rated securities.

     (BULLET)  The  Fund  may,  for  temporary  defensive  purposes,   invest  a
       percentage of its total assets,  without  limitation,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market instruments

                                       4

<PAGE>

       tends to fall when current  interest rates rise. Money market instruments
       are generally  less  sensitive to interest rate changes than  longer-term
       securities. When the Fund's assets are invested in these instruments, the
       Fund may not be achieving its investment objective.

     (BULLET)  International  investing is subject to special risks,  including,
       but not limited to, currency exchange rate volatility,  political, social
       or economic instability,  and differences in taxation, auditing and other
       financial practices.

     (BULLET) The Fund may experience  relatively large purchases or redemptions
       due to  asset  allocation  decisions  made  by the  Adviser  for  clients
       receiving  asset  allocation   account   management   services  involving
       investments in the Fund. These transactions may have a material effect on
       the Fund, since  redemptions  caused by  reallocations  may result in the
       Fund selling portfolio  securities it might not otherwise sell, resulting
       in  a  higher   portfolio   turnover  rate,   and  purchases   caused  by
       reallocations may result in the Fund receiving  additional cash that will
       remain  uninvested  until  additional  securities  can be purchased.  The
       Adviser will attempt to minimize the effects of these transactions at all
       times.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.


PRIOR PERFORMANCE

     ANNUAL TOTAL RETURNS AS OF DECEMBER 31

     The bar chart below shows the  variability  of the annual total returns for
the Investor  Class of the Fund for the last two calendar  years.  The bar chart
provides  some  indication  of the  risks of  investing  in the Fund by  showing
changes in the  performance of the Fund's Investor Class from year to year. Past
performance is not  necessarily an indicator of how the Fund will perform in the
future.

                   28.34%                  (0.77%)

     Since  inception  (January 16, 1997),  the highest  calendar  quarter total
return for the  Investor  Class of the Fund was 15.30%  (quarter  ended June 30,
1998) and the lowest calendar  quarter total return was (16.07)%  (quarter ended
September 30, 1998).  The total return was (10.98)% for the calendar nine months
ended September 30, 1999.

     AVERAGE ANNUAL TOTAL RETURNS -- COMPARISON

     The table below shows how the Fund's  average  annual total returns for the
past one calendar year and since inception,  with respect to the Investor Class,
compare with the Standard & Poor's 500 Composite Stock Price Index (the "S&P 500
Index") for the same periods.  The S&P 500 Index is an unmanaged  index composed
of 500 common stocks,  most of which are listed on the New York Stock  Exchange.
The S&P 500 Index assigns  relative  values to the stocks included in the index,
weighted  accordingly  to each stock's total market value  relative to the total
market value of the other stocks included in the index. The table,  like the bar
chart, provides some indication of the risks of investing in the Fund by showing
how the Fund's  average  annual  total  returns  for 1 year and since  inception
compare with those of a broad measure of market performance. Past performance is
not necessarily an indicator of how the Fund will perform in the future.

EXPENSES AND FEES

     Fund investors pay various  expenses,  either  directly or indirectly.  The
purpose of the following  table and example is to describe the fees and expenses
that you may pay if you buy and hold shares of the  Investor  Class of the Fund.
The table is based on expenses for the  Investor  Class of the Fund for the most
recent fiscal year ended August 31, 1999.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Investor Class of the Fund with the cost of investing in other mutual funds. The
example  assumes that you invest  $10,000 in the Investor  Class of the Fund for
the time periods indicated and then redeem all of your shares at the end of each
period.  The example also assumes that your investment has a 5% return each year
and that the  operating  expenses of the  Investor  Class of the Fund remain the
same,  except  for the  expiration  of the fee  waivers  and  reimbursements  on
December 31, 2000.  Although your actual costs may be higher or lower,  based on
these assumptions your cost would be:

              1 YEAR        3 YEARS        5 YEARS       10 YEARS
              ------        -------        -------       --------

BOSTON PARTNERS MID CAP VALUE FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

EQUITY  SECURITY:  A  security,  such as a stock,  representing  ownership  of a
company.  Bonds,  in  comparison,  are  referred  to  as  fixed-income  or  debt
securities because they represent indebtedness to the bondholder, not ownership.

MARKET  CAPITALIZATION:  Market  capitalization  refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

VALUE  CHARACTERISTICS:  Stocks are  generally  divided into the  categories  of
"growth" or "value." Value stocks appear to the Adviser to be undervalued by the
market as measured by certain  financial  formulas.  Growth stocks appear to the
Adviser to have  earnings  growth  potential  that is greater than the market in
general,  and whose  growth in revenue is expected  to continue  for an extended
period of time.

EARNINGS GROWTH:  The increased rate of growth in a company's earnings per share
from period to period.  Security  analysts  attempt to identify  companies  with
earnings growth potential  because a pattern of earnings growth generally causes
share prices to increase.
================================================================================

INVESTMENT GOALS

     The Fund seeks to provide  long-term  growth of capital  primarily  through
investment in equity securities. Current income is a secondary goal.

PRIMARY INVESTMENT STRATEGIES

     The Fund pursues its goal by investing,  under normal market conditions, at
least 65% of its total assets in a diversified portfolio consisting primarily of
equity securities, such as common stocks of issuers with a market capitalization
of between $200 million and $6 billion and  identified by Boston  Partners Asset
Management L.P. (the "Adviser") as having value characteristics.

     The   Adviser   examines   various   factors  in   determining   the  value
characteristics  of such issuers  including price to book value ratios and price
to earnings ratios.  These value  characteristics are examined in the context of
the issuer's operating and financial  fundamentals such as return on equity, and
earnings growth and cash flow. The Adviser selects securities for the Fund based
on a continuous study of trends in industries and companies,  earnings power and
growth and other investment criteria.

     The  Fund  may  also  invest  up to 20% of its  total  assets  in non  U.S.
dollar-denominated securities.

     In general, the Fund's investments are broadly diversified over a number of
industries  and,  as a matter of  policy,  the Fund is limited  to  investing  a
maximum of 25% of its total assets in any one industry.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the  above-mentioned  policies,  the Fund reserves the right to
hold up to 100% of its assets,  as a temporary  defensive  measure,  in cash and
eligible  U.S.  dollar-denominated  money market  instruments.  The Adviser will
determine when market conditions warrant temporary defensive measures.

KEY RISKS

     (BULLET) At least 65% of the Fund's  total  assets will be  invested  under
       normal market conditions in a diversified portfolio of equity securities,
       and the net asset value  ("NAV") of the Fund will change with  changes in
       the market value of its portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET)  The  Fund  may,  for  temporary  defensive  purposes,   invest  a
       percentage of its total assets,  without  limitation,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market  instruments tends to fall when current interest rates rise. Money
       market  instuments  are generally less sensitive to interest rate changes
       than longer-term securities. When the Fund's assets are invested in these
       instruments, the Fund may not be achieving its investment objective.

                                       9
<PAGE>

     (BULLET) Although the Fund will invest in stocks the Adviser believes to be
       undervalued,  there is no guarantee  that the prices of these stocks will
       not move even lower.

     (BULLET) International  investing is  subject to special risks,  including,
       but not limited to, currency exchange rate volatility,  political, social
       or economic instability,  and differences in taxation, auditing and other
       financial practices.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

past one calendar year and since inception,  with respect to the Investor Class,
compare with the Russell 2500 Index for the same periods. The Russell 2500 Index
is an unmanaged index (with no defined  investment  objective) of common stocks,
includes  reinvestment  of dividends and is a registered  trademark of the Frank
Russell Corporation.  The table, like the bar chart, provides some indication of
the risks of  investing  in the Fund by showing  how the Fund's  average  annual
total  returns  for 1 year and since  inception  compare  with  those of a broad
measure of market performance.  Past performance is not necessarily an indicator
of how the Fund will perform in the future.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Investor Class of the Fund with the cost of investing in other mutual funds. The
example  assumes that you invest  $10,000 in the Investor  Class of the Fund for
the time periods indicated and then redeem all of your shares at the end of each
period.  The example also assumes that your investment has a 5% return each year
and that the  operating  expenses of the  Investor  Class of the Fund remain the
same,  except  for the  expiration  of the fee  waivers  and  reimbursements  on
December 31, 2000.  Although your actual costs may be higher or lower,  based on
these assumptions your cost would be:

              1 YEAR        3 YEARS        5 YEARS       10 YEARS

BOSTON PARTNERS MICRO CAP VALUE FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

EQUITY  SECURITY:  A  security,  such as a stock,  representing  ownership  of a
company.  Bonds,  in  comparison,  are  referred  to  as  fixed-income  or  debt
securities because they represent indebtedness to the bondholder, not ownership.

MARKET  CAPITALIZATION:  Market  capitalization  refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

VALUE  CHARACTERISTICS:  Stocks are  generally  divided into the  categories  of
"growth" or "value." Value stocks appear to the Adviser to be undervalued by the
market as measured by certain  financial  formulas.  Growth stocks appear to the
Adviser to have  earnings  growth  potential  that is greater than the market in
general,  and whose  growth in revenue is expected  to continue  for an extended
period of time.

EARNINGS GROWTH:  The increased rate of growth in a company's earnings per share
from period to period.  Security  analysts  attempt to identify  companies  with
earnings growth potential  because a pattern of earnings growth generally causes
share prices to increase.

ADRS AND  EDRS:  Receipts  typically  issued  by a United  States  bank or trust
company evidencing ownership of underlying foreign securities.
================================================================================

INVESTMENT GOALS

     The Fund seeks long-term growth of capital primarily through  investment in
equity securities. Current income is a secondary objective.

PRIMARY INVESTMENT STRATEGIES

     The Fund pursues its goal by investing,  under normal market conditions, at
least 65% of its total assets in a diversified portfolio consisting primarily of
equity securities of issuers with market capitalizations that do not exceed $500
million  when  purchased by the Fund and  identified  by Boston  Partners  Asset
Management L.P. (the "Adviser") as having value characteristics.

     The Fund generally invests in the equity securities of small companies. The
Adviser  will seek to invest in companies it considers to be well managed and to
have attractive  fundamental  financial  characteristics.  The Adviser  believes
greater potential for price appreciation exists among small companies since they
tend to be less widely  followed by other  securities  analysts  and thus may be
more likely to be  undervalued  by the market.  The Fund may invest from time to
time a portion of its assets, not to exceed 35% (under normal conditions) at the
time of purchase, in companies with considerably larger market capitalizations.

     The   Adviser   examines   various   factors  in   determining   the  value
characteristics  of such issuers  including price to book value ratios and price
to earnings ratios.  These value  characteristics are examined in the context of
the issuer's  operating  and  financial  fundamentals  such as return on equity,
earnings growth and cash flow. The Adviser selects securities for the Fund based
on a fundamental analysis of industries and companies, earnings power and growth
and other investment criteria.

     The Fund may invest up to 25% of its total assets in equity  securities  of
foreign issuers,  including American  Depository  Receipts ("ADRs") and European
Depository Receipts ("EDRs").

     In general, the Fund's investments are broadly diversified over a number of
industries  and,  as a matter of  policy,  the Fund is limited  to  investing  a
maximum of 25% of its total assets in any one industry.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the  above-mentioned  policies,  the Fund reserves the right to
hold up to 100% of its assets,  as a temporary  defensive  measure,  in cash and
eligible  U.S.  dollar-denominated  money market  instruments.  The Adviser will
determine when market conditions warrant temporary defensive measures.

                                       13

<PAGE>


KEY RISKS

     (BULLET) At least 65% of the Fund's  total  assets  will be  invested  in a
       diversified  portfolio  of equity  securities,  and the net  asset  value
       ("NAV") of the Fund will change with  changes in the market  value of its
       portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) Although the Fund will invest in stocks the Adviser believes to be
       undervalued,  there is no guarantee  that the prices of these stocks will
       not move even lower.

     (BULLET) The Fund will invest in smaller  issuers  which are more  volatile
       than  investments  in issuers with a market  capitalization  greater than
       $500 million.  Small market capitalization issuers are not as diversified
       in their  business  activities as issuers with market values greater than
       $500 million and are more susceptible to changes in the business cycle.

     (BULLET) The equity  securities  in which the Fund  invests  will often  be
       traded only in the  over-the-counter  market or on a regional  securities
       exchange,  may be listed only in the quotation  service commonly known as
       the  "pink  sheets,"  and may not be traded  every  day or in the  volume
       typical  of  trading  on a national  securities  exchange.  These  equity
       securities may also be subject to wide  fluctuations in market value. The
       trading market for any given equity security may be sufficiently small as
       to make it difficult  for the Fund to dispose of a  substantial  block of
       such equity securities.  The sale by the Fund of portfolio  securities to
       meet  redemptions  may  require  the Fund to sell these  securities  at a
       discount  from market  prices or during  periods  when,  in the Adviser's
       judgement, such sale is not desirable. Moreover, the lack of an efficient
       market for these securities may make them difficult to value.

     (BULLET) International  investing  is subject to special risks,  including,
       but not limited to, currency exchange rate volatility,  political, social
       or economic instability,  and differences in taxation, auditing and other
       financial practices.

     (BULLET) If the Fund frequently trades its portfolio  securities,  the Fund
       will incur higher  brokerage  commissions  and transaction  costs,  which
       could lower the Fund's  performance.  In  addition to lower  performance,
       high portfolio turnover could result in taxable capital gains. The annual
       portfolio  turnover  rate for the Fund is not  expected  to exceed  150%,
       however,  it may be higher if the Adviser  believes  it will  improve the
       Fund's performance.

     (BULLET) The  Fund  may,  for  temporary   defensive  purposes,   invest  a
       percentage of its total assets,  without  limitation,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market  instruments tends to fall when current interest rates rise. Money
       market  instruments are generally less sensitive to interest rate changes
       than longer-term securities. When the Fund's assets are invested in these
       instruments, the Fund may not be achieving its investment objective.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

EXPENSES AND FEES

     Fund investors pay various  expenses,  either  directly or indirectly.  The
purpose of the following  table and example is to describe the fees and expenses
that you may pay if you buy and hold shares of the  Investor  Class of the Fund.
The table is based upon expenses for the Investor Class of the Fund for the most
recent fiscal year ended August 31, 1999.

                                                                  INVESTOR CLASS
                                                                  --------------
     SHAREHOLDER FEES (fees paid directly from your investment)

     Maximum sales charge imposed on purchases ..................      None
     Maximum deferred sales charge ..............................      None
     Maximum sales charge imposed on reinvested dividends .......      None
     Redemption Fee(1) ..........................................      1.00%
     Exchange Fee ...............................................      None

     ANNUAL FUND OPERATING EXPENSES (expenses that are deducted
     from Fund assets)

     Management fees ............................................      1.25%
     Distribution (12b-1) fees ..................................      0.25%
     Other expenses(2) ..........................................     16.56%
                                                                      -----
         Total annual Fund operating expenses ...................     18.06%
     Fee waivers and expense reimbursements(3) ..................     16.29%
                                                                      -----
     Net expenses ...............................................      1.77%
                                                                     ======

     (1) To prevent the Fund from being  adversely  affected by the  transaction
         costs  associated with short-term  shareholder  transactions,  the Fund
         will  redeem  shares  at a price  equal to the net  asset  value of the
         shares,  less an additional  transaction  fee equal to 1.00% of the net
         asset  value of all such shares  redeemed  that have been held for less
         than one year.  Such fees are not sales charges or contingent  deferred
         sales  charges,  but are  retained  by the Fund for the  benefit of all
         shareholders.

     (2) "Other  expenses"  include  audit,   administration,   custody,  legal,
         registration,  transfer agency and miscellaneous  other charges for the
         Investor Class.

     (3) The Adviser  has agreed that until  December  31,  2000,  it will waive
         advisory  fees and  reimburse  expenses to the extent that total annual
         Fund operating expenses exceed 1.77%.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Investor Class of the Fund with the cost of investing in other mutual funds. The
example  assumes that you invest  $10,000 in the Investor  Class of the Fund for
the time periods indicated and then redeem all of your shares at the end of each
period.  The example also assumes that your investment has a 5% return each year
and that the  operating  expenses of the  Investor  Class of the Fund remain the
same,  except  for the  expiration  of the fee  waivers  and  reimbursements  on
December 31, 2000.  Although your actual costs may be higher or lower,  based on
these assumptions your cost would be:

              1 YEAR        3 YEARS        5 YEARS       10 YEARS
              ------        -------        -------       --------
               $180         $3,437         $5,900         $9,736

BOSTON PARTNERS BOND FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS
TOTAL RETURN:  A way of measuring Fund  performance.  Total return is based on a
calculation that takes into account income dividends, capital gain distributions
and the increase or decrease in share price.
FIXED-INCOME SECURITIES:  Fixed-income securities are generally bonds, which are
a type of  security  that  functions  like a loan.  Bonds are  "IOUs"  issued by
private companies,  municipalities or government agencies.  By comparison,  when
you buy a stock, you are buying ownership in a company. With a bond, your "loan"
is for a specific  period,  usually 5 to 30 years.  You receive regular interest
payments at a fixed rate. Hence the term "fixed-income" security.
INVESTMENT-GRADE FIXED-INCOME SECURITIES: Securities which are rated at the time
of  purchase  "AAA,"  "AA," "A," or "BBB" by S&P,  "Aaa,"  "Aa," "A" or "Baa" by
Moody's or which are  similarly  rated by  another  Rating  Organization  or are
unrated but deemed by the  Adviser to be  comparable  in quality to  instruments
that are so rated.  Debt securities  rated "BBB" by S&P, "Baa" by Moody's or the
equivalent   rating  of  another   Rating   Organization,   while  still  deemed
investment-grade,  are considered to have  speculative  characteristics  and are
more sensitive to economic change than higher rated bonds.
CORPORATE DEBT OBLIGATIONS: A long-term bond issued by a corporation,  including
railroads and public utilities.
MORTGAGE-BACKED  SECURITIES:  Pools  of  mortgage  loans  assembled  for sale to
investors by various governmental agencies as well as by private issuers.
ASSET-BACKED SECURITIES: Pools of assets, usually loans such as installment sale
contracts or credit card receivables, assembled for sale by private issuers.
MATURITY:  The date on which an investor in a fixed income security will be paid
in full by the issuer.
================================================================================

INVESTMENT GOALS

     The Fund  seeks to  maximize  total  return  by  investing  principally  in
investment grade fixed-income securities. Current income is a secondary goal.

PRIMARY INVESTMENT STRATEGIES

     The Fund invests  (during  normal  market  conditions)  at least 75% of its
total assets in bonds,  including corporate debt obligations and mortgage-backed
and   asset-backed   securities   (collectively,    "Debt   Securities")   rated
investment-grade  or better at the time of purchase by Standard & Poor's Ratings
Group  ("S&P") or  Moody's  Investors  Service,  Inc.  ("Moody's")  or which are
similarly rated by another nationally recognized statistical rating organization
("Rating  Organization").  The Fund may also purchase Debt Securities  which are
unrated but deemed by Boston  Partners Asset  Management L.P. (the "Adviser") to
be comparable in quality to investment-grade instruments. The Fund may invest up
to 25% of its total assets in Debt  Securities  rated "Ba" and "B" by Moody's or
"BB" and "B" by S&P or which are similarly rated by another Rating  Organization
(i.e.,  high  yield,  high risk  securities)  or are  unrated  but deemed by the
Adviser to be comparable in quality to instruments that are so rated.

KEY RISKS

     (BULLET) The net asset value  ("NAV") of the Fund will change with  changes
       in the market value of its portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) The Fund is subject to interest rate risk.  Rising  interest rates
       cause the prices of  fixed-income  securities  to  decrease  and  falling
       interest rates cause the prices of  fixed-income  securities to increase.
       Securities with longer  maturities can be more sensitive to interest rate
       changes.  In effect,  the longer the maturity of a security,  the greater
       the impact a change in interest rates could have on the security's price.

     (BULLET) High yield, high risk fixed-income  securities have a greater risk
       of default in the payment of interest  and  principal  than higher  rated
       securities and are subject to significant changes in price. Investment by
       the Fund in such  securities  involves a high  degree of credit  risk and
       such securities are regarded as speculative by the major rating agencies.

     (BULLET) If the Fund frequently trades its portfolio  securities,  the Fund
       will incur higher  brokerage  commissions  and transaction  costs,  which
       could lower the Fund's  performance.  In  addition to lower  performance,
       high

                                       17
<PAGE>

       portfolio  turnover  could  result in  taxable  capital gains. The annual
       portfolio  turnover  rate for the Fund is not  expected  to exceed  100%,
       however,  it may be higher if the Adviser  believes  it will  improve the
       Fund's performance.

     (BULLET) The Fund may experience  relatively large purchases or redemptions
       due to  asset  allocation  decisions  made  by the  Adviser  for  clients
       receiving  asset  allocation   account   management   services  involving
       investments in the Fund. These transactions may have a material effect on
       the Fund, since  redemptions  caused by  reallocations  may result in the
       Fund selling portfolio  securities it might not otherwise sell, resulting
       in  a  higher   portfolio   turnover  rate,   and  purchases   caused  by
       reallocations may result in the Fund receiving  additional cash that will
       remain  uninvested  until  additional  securities  can be purchased.  The
       Adviser will attempt to minimize the effects of these transactions at all
       times.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

     AVERAGE ANNUAL TOTAL RETURNS -- COMPARISON

     The table below shows how the Fund's  average  annual total returns for the
past one calendar year and since inception,  with respect to the Investor Class,
compare  with the Lehman  Brothers  Aggregate  Index for the same  periods.  The
Lehman Brothers  Aggregate Index is an unmanaged index  containing  fixed-income
securities rated  investment grade or higher by Moody's,  S&P or Fitch Investors
Service.  All issues have at least one year to maturity and an  outstanding  par
value of at  least  $100  million.  The  Lehman  Brothers  Aggregate  Index is a
registered  trademark of Lehman  Brothers,  Inc. The table,  like the bar chart,
provides  some  indication  of the risks of investing in the Fund by showing how
the Fund's average annual total returns for 1 year and since  inception  compare
with those of a broad measure of market  performance.  Past  performance  is not
necessarily an indicator of how the Fund will perform in the future.

EXPENSES AND FEES

     Fund investors pay various  expenses,  either  directly or indirectly.  The
purpose of the following  table and example is to describe the fees and expenses
that you may pay if you buy and hold shares of the  Investor  Class of the Fund.
The table is based upon expenses for the Investor Class of the Fund for the most
recent fiscal year ended August 31, 1999.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Investor Class of the Fund with the cost of investing in other mutual funds. The
example  assumes that you invest  $10,000 in the Investor  Class of the Fund for
the time periods indicated and then redeem all of your shares at the end of each
period.  The example also assumes that your investment has a 5% return each year
and that the  operating  expenses of the  Investor  Class of the Fund remain the
same,  except  for the  expiration  of the fee  waivers  and  reimbursements  on
December 31, 2000.  Although your actual costs may be higher or lower,  based on
these assumptions your cost would be:

              1 YEAR        3 YEARS        5 YEARS       10 YEARS

equity  securities,  while  seeking to minimize  the impact of  movements in the
equity markets.

EQUITY  SECURITY:  A  security,  such as a stock,  representing  ownership  of a
company.  Bonds,  in  comparison,  are  referred  to  as  fixed-income  or  debt
securities because they represent indebtedness to the bondholder, not ownership.

calculation that takes into account income dividends, capital gain distributions
and the increase or decrease in share price.

SALOMON SMITH BARNEY U.S. 1-MONTH TREASURY BILL INDEX(TRADE  MARK): An unmanaged
index  containing  monthly  return  equivalents  of yield  averages that are not
marked to market.

SHORT  SALE:  A sale by the Fund of a security  which has been  borrowed  from a
third party on the expectation  that the market price will drop. If the price of
the security  drops,  the Fund will make a profit by purchasing  the security in
the open market at a lower price than the one at which it sold the security.  If
the price of the security  rises,  the Fund may have to cover its short position
at a higher price than the short sale price, resulting in a loss.

SHORT-TERM CASH INSTRUMENTS: These temporary investments include notes issued or
guaranteed by the U.S. Government, its agencies or instrumentalities; commercial
paper  rated in the two  highest  rating  categories;  certificates  of deposit;
repurchase agreements and other high-grade corporate debt securities.

FEDERAL FUNDS RATE: The rate of interest  charged by a Federal  Reserve bank for
member banks to borrow their federally required reserve.

MARKET  CAPITALIZATION:  Market  capitalization  refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

ADRS:  Receipts  typically  issued  by a United  States  bank or  trust  company
evidencing ownership of underlying foreign securities.
================================================================================

INVESTMENT GOALS

     The Fund seeks long-term capital  appreciation while minimizing exposure to
general  equity market risk.  The Fund seeks a total return greater than that of
the Salomon Smith Barney U.S. 1-Month Treasury Bill Index.(TRADE MARK)

PRIMARY INVESTMENT STRATEGIES

     The Fund invests in long positions in stocks  identified by Boston Partners
Asset  Management  L.P. (the  "Adviser") as undervalued  and short  positions in
stocks that the Adviser has  identified  as  overvalued.  The cash proceeds from
short sales will be invested in short-term cash  instruments to produce a return
on such  proceeds  just below the federal  funds  rate.  The Fund will invest in
securities  principally  traded in the United States  markets.  The Adviser will
determine  the size of each long or short  position by  analyzing  the  tradeoff
between the  attractiveness  of each  position and its impact on the risk of the
overall portfolio.  The Fund seeks to construct a portfolio that has minimal net
exposure  to the  United  States  equity  market  generally  and low to  neutral
exposure to specific industries,  specific market  capitalization  ranges (e.g.,
large cap, mid cap and small cap) and certain other factors.

     The Fund's long and short  positions  may involve  (without  limit)  equity
securities  of  foreign  issuers  that are  traded in the  markets of the United
States as sponsored American  Depository  Receipts  ("ADRs").  The Fund may also
invest up to 20% of its total assets  directly in equity  securities  of foreign
issuers.

     To meet margin requirements,  redemptions or pending investments,  the Fund
may also  temporarily  hold a portion  of its  assets in full  faith and  credit
obligations of the United States government and in short-term notes,  commercial
paper or other money market instruments.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the  above-mentioned  policies,  the Fund reserves the right to
hold up to 100% of its assets,  as a temporary  defensive  measure,  in cash and
eligible  U.S.  dollar-denominated  money market  instruments.  The Adviser will
determine when market conditions warrant temporary defensive measures.

KEY RISKS

     (BULLET) The net asset value  ("NAV") of the Fund will change with  changes
       in the market value of its portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) The Fund is subject  to the risk of poor  stock  selection  by the
       Adviser.  In  other  words,  the  Adviser  may not be  successful  in its
       strategy  of  taking  long  positions  in  undervalued  stocks  and short
       positions in overvalued  stocks.  Further,  since the Adviser will manage
       both a long and a short portfolio, there is the risk that the Adviser may
       make more poor  investment  decisions  than an adviser of a typical stock
       mutual fund with only a long portfolio may make.

     (BULLET) Short  sales of  securities  may result in gains  if a  security's
       price declines,  but may result in losses if a security's  price does not
       decline in price.

     (BULLET) The Fund could lose money if a seller under a repurchase agreement
       defaults or declares bankruptcy.

     (BULLET) Securities  held in a segregated  account cannot be sold while the
       position it is covering is  outstanding,  unless they are  replaced  with
       similar securities.  As a result, there is a possibility that segregation
       of a  large  percentage  of the  Fund's  assets  could  impede  portfolio
       management  or the Fund's  ability to meet  redemption  requests or other
       current obligations.

     (BULLET) The  Fund  may,  for  temporary   defensive  purposes,   invest  a
       percentage of its total assets,  without  limitation,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market  instruments tends to fall when current interest rates rise. Money
       market  instruments are generally less sensitive to interest rate changes
       than longer-term securities. When the Fund's assets are invested in these
       instruments, the Fund may not be achieving its investment objective.

     (BULLET) The risks of international  investing include, but are not limited
       to,  currency  exchange rate  volatility,  political,  social or economic
       instability,  and  differences in taxation,  auditing and other financial
       practices.

     (BULLET) If the Fund frequently trades its portfolio  securities,  the Fund
       will incur higher  brokerage  commissions  and transaction  costs,  which
       could lower the Fund's  performance.  In  addition to lower  performance,
       high portfolio turnover could result in taxable capital gains. The annual
       portfolio  turnover  rate for the Fund is not  expected  to exceed  200%,
       however,  it may be higher if the Adviser  believes  it will  improve the
       Fund's performance.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

EXPENSES AND FEES

     Fund investors pay various  expenses,  either  directly or indirectly.  The
purpose of the following  table and example is to describe the fees and expenses
that you may pay if you buy and hold shares of the  Investor  Class of the Fund.
The table is based on expenses for the Investor Class of the Fund for the period
November 17, 1998 (commencement of operations) through August 31, 1999.

                                                                  INVESTOR CLASS
                                                                  --------------

     SHAREHOLDER FEES (fees paid directly from your investment)

     Maximum sales charge imposed on purchases ...................      None
     Maximum deferred sales charge ...............................      None
     Maximum sales charge imposed on reinvested dividends ........      None
     Redemption Fee(1) ...........................................      1.00%
     Exchange Fee ................................................      None

     ANNUAL FUND OPERATING EXPENSES (expenses that are deducted
     from Fund assets)

     Management fees .............................................      2.25%
     Distribution (12b-1) fees ...................................      0.25%
     Other expenses(2) ...........................................     24.08%
                                                                       -----
         Total annual Fund operating expenses ....................     26.58%
     Fee waivers and expense reimbursements(3) ...................     23.41%
                                                                       -----
     Net expenses ................................................      3.17%
                                                                       -----

     (1) To prevent the Fund from being  adversely  affected by the  transaction
         costs  associated with short-term  shareholder  transactions,  the Fund
         will  redeem  shares  at a price  equal to the net  asset  value of the
         shares,  less an additional  transaction  fee equal to 1.00% of the net
         asset  value of all such shares  redeemed  that have been held for less
         than one year.  Such fees are not sales charges or contingent  deferred
         sales  charges,  but are  retained  by the Fund for the  benefit of all
         shareholders.

     (2) "Other  expenses"  include  audit,   administration,   custody,  legal,
         registration,  transfer agency and miscellaneous  other charges for the
         Investor  Class.  "Other  expenses"  and "Total  annual Fund  operating
         expenses" include dividends on securities which the Fund has sold short
         ("short-sale  dividends").  Short-sale  dividends  generally reduce the
         market value of the  securities by the amount of the dividend  declared
         -- thus  increasing the Fund's  unrealized  gain or reducing the Fund's
         unrealized loss on the securities sold short.  Short-sale dividends are
         treated as an expense,  and increase the Fund's  total  expense  ratio,
         although  no  cash is  received  or paid by the  Fund.  The  amount  of
         short-sale  dividends  is  estimated at 0.45% of average net assets for
         the current fiscal year.

     (3) The Adviser  has agreed that until  December  31,  2000,  it will waive
         advisory  fees and  reimburse  expenses to the extent that total annual
         Fund operating  expenses  exceed 2.72%  (excluding  short sale dividend
         expenses).

EXAMPLE
     The example is intended  to help you compare the cost of  investing  in the
Investor Class of the Fund with the cost of investing in other mutual funds. The
example  assumes that you invest  $10,000 in the Investor  Class of the Fund for
the time periods indicated and then redeem all of your shares at the end of each
period.  The example also assumes that your investment has a 5% return each year
and that the  operating  expenses of the  Investor  Class of the Fund remain the
same,  except  for the  expiration  of the fee  waivers  and  reimbursements  on
December 31, 2000.  Although your actual costs may be higher or lower,  based on
these assumptions your cost would be:

             1 YEAR         3 YEARS         5 YEARS        10 YEARS
             ------         -------         -------        --------
              $320          $4,628          $7,277         $10,254

FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------

     The table below sets forth certain  financial  information  for the periods
indicated,  including per share information results for a single Fund share. The
term "Total Return"  indicates how much your investment  would have increased or
decreased  during this period of time and assumes that you have  reinvested  all
dividends and  distributions.  This information has been derived from the Fund's
financial  statements  audited  by  PricewaterhouseCoopers  LLP,  the  Company's
independent accountants. This information should be read in conjunction with the
Fund's  financial  statements  which,  together  with the report of  independent
accountants,  are included in the Fund's annual report,  which is available upon
request (see back cover for ordering instructions).

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING OF FUND SHARES

     Investor Shares of the Funds ("Shares") are priced at their net asset value
("NAV"). The NAV for the Investor Class of each Fund is calculated by adding the
value of all securities, cash and other assets in a Fund's portfolio,  deducting
the Fund's  actual and accrued  liabilities  and dividing by the total number of
Shares outstanding.

     Each Fund's NAV is calculated once daily at the close of regular trading on
the New York Stock Exchange ("NYSE") (currently 4:00 p.m. Eastern time) each day
the NYSE is open.  Shares  will not be  priced  on the days on which the NYSE is
closed.

     Securities  held by a Fund are valued  using the closing  price or the last
sale price on a national  securities  exchange or on the NASDAQ  National Market
System  where  they  are  traded.  If  there  were no  sales  on that day or the
securities are traded on other over-the-counter markets, the mean of the bid and
asked prices is used.  Short-term debt investments  having maturities of 60 days
or less are amortized to maturity based on their cost.  With the approval of the
Company's  Board  of  Directors,  a Fund  may  use a  pricing  service,  bank or
broker-dealer  experienced in providing valuations to value a Fund's securities.
If market quotations are unavailable, securities will be valued at fair value as
determined  in good faith by the  investment  adviser  according  to  procedures
adopted by the Company's Board of Directors.

PURCHASE OF FUND SHARES

     Shares  representing  interests in the Funds are offered  continuously  for
sale by Provident Distributors, Inc. (the "Distributor"). The Board of Directors
of the Company has approved  and adopted a  Distribution  Agreement  and Plan of
Distribution  for the Shares  (the  "Plan")  pursuant  to Rule  12b-1  under the
Investment  Company Act of 1940.  Under the Plan, the Distributor is entitled to
receive from the Funds a distribution  fee with respect to the Shares,  which is
accrued  daily and paid monthly,  of up to 0.25% on an  annualized  basis of the
average daily net assets of the Shares.  The actual amount of such  compensation
under the Plan is agreed upon by the  Company's  Board of  Directors  and by the
Distributor.  Because these fees are paid out of the Funds' assets on an ongoing
basis,  over time these fees will increase the cost of your  investment  and may
cost you more than paying other types of sales charges.

     Amounts  paid  to  the  Distributor  under  the  Plan  may be  used  by the
Distributor  to cover  expenses  that are related to (i) the sale of the Shares,
(ii) ongoing servicing and/or  maintenance of the accounts of Shareholders,  and
(iii)  sub-transfer  agency services,  subaccounting  services or administrative
services related to the sale of the Shares, all as set forth in the Funds' 12b-1
Plan.  The  Distributor  may delegate some or all of these  functions to Service
Organizations. See "Purchases Through Intermediaries" below.

     The Plan obligates the Fund,  during the period it is in effect,  to accrue
and pay to the  Distributor  on behalf of the Shares the fee agreed to under the
Distribution  Agreement.  Payments  under the Plan are not tied  exclusively  to
expenses  actually  incurred by the  Distributor,  and the  payments  may exceed
distribution expenses actually incurred.

     PURCHASES  THROUGH  INTERMEDIARIES.  Shares of the  Funds may be  available
through  certain  brokerage  firms,  financial  institutions  and other industry
professionals (collectively,  "Service Organizations").  Certain features of the
Shares,  such as the  initial and  subsequent  investment  minimums  and certain
trading  restrictions,  may be  modified  or  waived by  Service  Organizations.
Service Organizations may impose transaction or administrative  charges or other
direct fees, which charges and fees would not be imposed if Shares are purchased
directly  from  the  Company.   Therefore,   you  should   contact  the  Service
Organization  acting on your  behalf  concerning  the fees (if any)  charged  in
connection  with a  purchase  or  redemption  of  Shares  and  should  read this
Prospectus  in light of the  terms  governing  your  accounts  with the  Service
Organization.   Service   Organizations   will  be   responsible   for  promptly
transmitting client or customer purchase and redemption orders to the Company in
accordance with their agreements with the Company and with clients or customers.
Service Organizations or, if applicable,  their designees that have entered into
agreements with the

                                       28

<PAGE>

Company or its agent may enter  confirmed  purchase  orders on behalf of clients
and customers, with payment to follow no later than the Company's pricing on the
following  Business  Day. If payment is not  received by such time,  the Service
Organization could be held liable for resulting fees or losses. The Company will
be deemed  to have  received  a  purchase  or  redemption  order  when a Service
Organization,  or, if applicable, its authorized designee, accepts a purchase or
redemption  order in good  order.  Orders  received by the Company in good order
will be priced at the  appropriate  Fund's net asset value next  computed  after
they are accepted by the Service Organization or its authorized designee.

     For administration,  subaccounting,  transfer agency and/or other services,
the Adviser,  the Distributor or their affiliates may pay Service  Organizations
and certain recordkeeping  organizations a fee of up to .35% (the "Service Fee")
of the average annual net asset value of accounts with the Company maintained by
such Service Organizations or recordkeepers.  The Service Fee payable to any one
Service Organization is determined based upon a number of factors, including the
nature and quality of service provided,  the operations processing  requirements
of  the   relationship   and  the  standardized  fee  schedule  of  the  Service
Organization or recordkeeper.

     GENERAL.  You may also  purchase  Shares  of each Fund at the NAV per share
next calculated after your order is received by PFPC Inc. (the "Transfer Agent")
in proper  form as  described  below.  After an initial  purchase  is made,  the
Transfer  Agent will set up an account  for you on RBB's  records.  The  minimum
initial investment in any Fund is $2,500 and the minimum  additional  investment
is $100.  For  purposes of meeting the minimum  initial  purchase,  purchases by
clients which are part of endowments, foundations or other related groups may be
combined. You can only purchase Shares of each Fund on days the NYSE is open and
through the means described below.

     INITIAL  INVESTMENT  BY MAIL.  An account may be opened by  completing  and
signing the  application  included  with this  Prospectus  and mailing it to the
Transfer  Agent  at the  address  noted  below,  together  with a check  ($2,500
minimum)  payable  to the Fund in which you would like to  invest.  Third  party
checks will not be accepted.

     BOSTON PARTNERS [NAME OF FUND]
     c/o PFPC Inc.
     P.O. Box 8852
     Wilmington, DE 19899-8852

     The  name  of  the  Fund  to be  purchased  should  be  designated  on  the
application  and should appear on the check.  Payment for the purchase of Shares
received  by mail will be  credited  to a  shareholder's  account at the NAV per
share of the Fund next determined after receipt of payment in good order.

     INITIAL  INVESTMENT BY WIRE. Shares of each Fund may be purchased by wiring
federal funds to PNC Bank (see instructions below). A completed application must
be  forwarded to the Transfer  Agent at the address  noted above under  "Initial
Investment by Mail" in advance of the wire. For each Fund,  notification must be
given to the Transfer Agent at (888) 261-4073 prior to 4:00 p.m.,  Eastern time,
on the wire date. (Prior  notification must also be received from investors with
existing accounts.) Funds should be wired to:

     PNC Bank, NA
     Philadelphia, Pennsylvania 19103
     ABA# 0310-0005-3
     Account # 86-1108-2507
     F/B/O BOSTON PARTNERS [NAME OF FUND]
     Ref. (Account Number)
     Shareholder Name

     Federal  funds  purchases  will be accepted only on a day on which the NYSE
and PNC Bank, NA are open for business.

                                       29

<PAGE>

     ADDITIONAL INVESTMENTS.  Additional  investments  may be  made at any  time
(minimum  investment $100) by purchasing  Shares of any Fund at NAV by mailing a
check to the Transfer Agent at the address noted above under "Initial Investment
by Mail" (payable to Boston  Partners [name of Fund]) or by wiring monies to PNC
Bank, NA as outlined  above under  "Initial  Investment by Wire." For each Fund,
notification must be given to the Transfer Agent at (888) 261-4073 prior to 4:00
p.m., Eastern time, on the wire date.  Initial and additional  purchases made by
check cannot be redeemed until payment of the purchase has been collected.

     AUTOMATIC INVESTMENT PLAN.  Additional  investments in  Shares of the Funds
may be made  automatically  by authorizing  the Transfer Agent to withdraw funds
from your bank account  through an  Automatic  Investment  Plan ($100  minimum).
Investors  desiring to participate in an Automatic  Investment  Plan should call
the Transfer Agent at (888) 261-4073 to obtain the appropriate forms.

     RETIREMENT PLANS.  Shares may be purchased  in conjunction  with individual
retirement  accounts ("IRAs") and rollover IRAs where PFPC Trust Company acts as
custodian.  For further  information as to applications and annual fees, contact
the Transfer Agent at (888)  261-4073.  To determine  whether the benefits of an
IRA are available and/or appropriate, you should consult with a tax adviser.

     OTHER PURCHASE  INFORMATION.  The Company  reserves the right,  in its sole
discretion, to suspend the offering of Shares or to reject purchase orders when,
in the  judgment of  management,  such  suspension  or  rejection is in the best
interests of the Funds. As of the date of this  Prospectus,  the Boston Partners
Micro Cap Value Fund  intends to suspend the  offering of Shares upon the Fund's
attaining $300 million in total assets.

REDEMPTION OF FUND SHARES

     You may  redeem  Shares  of the  Funds at the next NAV  calculated  after a
redemption  request is received by the Transfer  Agent in proper  form.  You can
only  redeem  Shares on days the NYSE is open and  through  the means  described
below.

     You may redeem Shares of each Fund by mail, or, if you are  authorized,  by
telephone.  The value of Shares  redeemed  may be more or less than the purchase
price,  depending on the market  value of the  investment  securities  held by a
Fund.  There is no charge for a redemption.  However,  if a  shareholder  of the
Boston  Partners Micro Cap Value or Boston Partners Market Neutral Funds redeems
Shares held for less than 1 year, a transaction fee of 1% of the net asset value
of the Shares redeemed at the time of redemption  will be charged.  For purposes
of this  redemption  feature,  shares  purchased  first will be considered to be
shares first redeemed.

     REDEMPTION BY MAIL. Your redemption  requests should be addressed to BOSTON
PARTNERS [name of Fund], c/o PFPC Inc., P.O. Box 8852, Wilmington, DE 19899-8852
and must include:

     a.  a letter  of  instruction  specifying  the  number  of shares or dollar
         amount to be redeemed, signed by all registered owners of the shares in
         the exact names in which they are registered;

     b.  any required  signature  guarantees,  which are  required  when (i) the
         redemption  request  proceeds are to be sent to someone  other than the
         registered shareholder(s) or (ii) the redemption request is for $10,000
         or more. A signature  guarantee may be obtained from a domestic bank or
         trust company,  broker, dealer,  clearing agency or savings association
         who  are  participants  in  a  Medallion  Program   recognized  by  the
         Securities  Transfer   Association.   The  three  recognized  Medallion
         Programs are Securities Transfer Agent Medallion Program (STAMP), Stock
         Exchanges  Medallion  Program (SEMP) and New York Stock Exchange,  Inc.
         Medallion Program (MSP). Signature Guarantees,  which are not a part of
         these programs, will not be accepted.  Please note that a notary public
         stamp or seal is not acceptable; and

     c.  other supporting legal documents,  if required, in the case of estates,
         trusts, guardianships, custodianships, corporations, pension and profit
         sharing plans and other organizations.

                                       30

<PAGE>

     REDEMPTION BY TELEPHONE.  In order to request a telephone  redemption,  you
must have returned your account application  containing a telephone election. To
add a telephone  redemption option to an existing account,  contact the Transfer
Agent by calling (888) 261-4073 for a Telephone Authorization Form.

     Once you are  authorized  to utilize the  telephone  redemption  option,  a
redemption  of Shares may be requested  by calling the  Transfer  Agent at (888)
261-4073 and requesting  that the  redemption  proceeds be mailed to the primary
registration address or wired per the authorized instructions.  If the telephone
redemption  option or the  telephone  exchange  option (as  described  below) is
authorized, the Transfer Agent may act on telephone instructions from any person
representing himself or herself to be a shareholder and believed by the Transfer
Agent to be genuine.  The  Transfer  Agent's  records of such  instructions  are
binding and  shareholders,  not the Company or the Transfer Agent, bear the risk
of loss in the event of  unauthorized  instructions  reasonably  believed by the
Company or the  Transfer  Agent to be genuine.  The  Transfer  Agent will employ
reasonable procedures to confirm that instructions communicated are genuine and,
if it  does  not,  it may be  liable  for  any  losses  due to  unauthorized  or
fraudulent  instructions.  The  procedures  employed  by the  Transfer  Agent in
connection with  transactions  initiated by telephone  include tape recording of
telephone instructions and requiring some form of personal  identification prior
to acting upon instructions received by telephone.

     SYSTEMATIC  WITHDRAWAL  PLAN.  If  your  account  has a value  of at  least
$10,000,  you may  establish a Systematic  Withdrawal  Plan and receive  regular
periodic payments.  A request to establish a Systematic  Withdrawal Plan must be
submitted in writing to the Transfer Agent at P.O. Box 8852, Wilmington Delaware
19899-8852. Each withdrawal redemption will be processed on or about the 25th of
the  month and  mailed  as soon as  possible  thereafter.  There are no  service
charges for maintenance; the minimum amount that you may withdraw each period is
$100.  (This is merely the minimum amount allowed and should not be mistaken for
a recommended amount.) The holder of a Systematic  Withdrawal Plan will have any
income  dividends  and any capital  gains  distributions  reinvested in full and
fractional shares at net asset value. To provide funds for payment,  Shares will
be  redeemed  in such  amount  as is  necessary  at the  redemption  price.  The
systematic  withdrawal  of Shares may reduce or  possibly  exhaust the Shares in
your  account,  particularly  in the event of a market  decline.  As with  other
redemptions,  a systematic  withdrawal  payment is a sale for federal income tax
purposes.  Payments  made  pursuant to a  Systematic  Withdrawal  Plan cannot be
considered as actual yield or income since part of such payments may be a return
of capital.

     You will ordinarily not be allowed to make  additional  investments of less
than the aggregate  annual  withdrawals  under the  Systematic  Withdrawal  Plan
during the time you have the plan in effect and,  while a Systematic  Withdrawal
Plan is in effect,  you may not make  periodic  investments  under the Automatic
Investment  Plan. You will receive a confirmation  of each  transaction  and the
Share and cash balance  remaining in your plan.  The plan may be  terminated  on
written   notice  by  the   shareholder  or  by  the  Fund  and  will  terminate
automatically if all Shares are liquidated or withdrawn from the account or upon
the death or  incapacity  of the  shareholder.  You may  change  the  amount and
schedule of  withdrawal  payments  or suspend  such  payments by giving  written
notice to the Fund's  transfer agent at least ten Business Days prior to the end
of the month preceding a scheduled payment.

     TRANSACTION  FEE ON CERTAIN  REDEMPTIONS  OF THE BOSTON  PARTNERS MICRO CAP
VALUE AND BOSTON PARTNERS MARKET NEUTRAL FUNDS

     The Boston  Partners  Micro Cap Value and Boston  Partners  Market  Neutral
Funds require the payment of a transaction fee on redemptions of Shares held for
less than one year equal to 1.00% of the net asset value of such Shares redeemed
at the time of redemption. This additional transaction fee is paid to each Fund,
NOT to the adviser, distributor or transfer agent. It is NOT a sales charge or a
contingent deferred sales charge. The fee does not apply to redeemed Shares that
were purchased through reinvested  dividends or capital gain distributions.  The
purpose of the additional  transaction fee is to indirectly allocate transaction
costs associated with redemptions to those investors  making  redemptions  after
holding their shares for a short period, thus protecting existing  shareholders.
These costs include:  (1) brokerage  costs; (2) market impact costs -- i.e., the
decrease in market prices which may result when a

                                       31

<PAGE>

Fund sells  certain  securities  in order to raise  cash to meet the  redemption
request;  (3) the realization of capital gains by the other shareholders in each
Fund; and (4) the effect of the "bid-ask" spread in the over-the-counter market.
The 1.00% amount  represents  each Fund's  estimate of the  brokerage  and other
transaction  costs which may be incurred by each Fund in  disposing of stocks in
which each Fund may invest.  Without the additional  transaction  fee, each Fund
would generally be selling its shares at a price less than the cost to each Fund
of acquiring  the  portfolio  securities  necessary  to maintain its  investment
characteristics,   resulting   in  reduced   investment   performance   for  all
shareholders in the Funds. With the additional  transaction fee, the transaction
costs of selling  additional stocks are not borne by all existing  shareholders,
but the  source of funds for these  costs is the  transaction  fee paid by those
investors  making  redemptions of the Boston Partners Micro Cap Value and Boston
Partners Market Neutral Funds.

     INVOLUNTARY  REDEMPTION.  The  Company  reserves  the  right  to  redeem  a
shareholder's account in any Fund at any time the net asset value of the account
in such Fund  falls  below  $500 as the result of a  redemption  or an  exchange
request.  Shareholders  will be  notified  in  writing  that the  value of their
account  in a Fund  is less  than  $500  and  will  be  allowed  30 days to make
additional  investments before the redemption is processed.  The transaction fee
applicable to the Boston  Partners  Micro Cap Value and Boston  Partners  Market
Neutral Funds will not be charged when shares are involuntarily redeemed.

     OTHER REDEMPTION  INFORMATION.  Redemption proceeds for Shares of the Funds
recently  purchased  by  check  may not be  distributed  until  payment  for the
purchase has been collected, which may take up to fifteen days from the purchase
date.
Shareholders can avoid this delay by utilizing the wire purchase option.

     Other than as described above,  payment of the redemption  proceeds will be
made within seven days after receipt of an order for a  redemption.  The Company
may suspend the right of  redemption or postpone the date at times when the NYSE
is closed or under any emergency circumstances as determined by the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the Funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a Fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The Funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a Fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a Fund.

EXCHANGE PRIVILEGE

     The exchange  privilege is available to shareholders  residing in any state
in which the Shares  being  acquired  may be legally  sold.  A  shareholder  may
exchange  Investor  Shares of any Boston  Partners  Fund for Investor  Shares of
another Boston  Partners Fund, up to six (6) times per year.  Such exchange will
be effected at the net asset value of the exchanged  Investor Shares and the net
asset value of the Investor Shares to be acquired next  determined  after PFPC's
receipt of a request for an exchange.  An exchange of Boston  Partners Micro Cap
Value or Boston  Partners  Market Neutral Shares held for less than 1 year (with
the  exception  of  Shares  purchased  through  dividend   reinvestment  or  the
reinvestment of capital gains) will be subject to the 1.00%  transaction fee. An
exchange of Shares will be treated as a sale for federal income tax purposes.  A
shareholder  may make an exchange by sending a written  request to the  Transfer
Agent or, if authorized, by telephone (see "Redemption by Telephone" above).

     If the exchanging shareholder does not currently own Investor Shares of the
Fund whose Shares are being acquired, a new account will be established with the
same  registration,  dividend and capital gain options as the account from which
shares are exchanged,  unless otherwise  specified in writing by the shareholder
with all signatures  guaranteed.  See  "Redemption  By Mail" for  information on
signature  guarantees.  The exchange  privilege may be modified or terminated at
any time, or from time to time, by the Company,  upon 60 days' written notice to
shareholders.

                                       32

<PAGE>

     If an exchange is to a new account in a Fund  advised by the  Adviser,  the
dollar value of the Shares  acquired must equal or exceed the Fund's minimum for
a new account; if to an existing account,  the dollar value must equal or exceed
the Fund's minimum for additional investments.  If an amount remains in the Fund
from which the  exchange is being made that is below the minimum  account  value
required, the account will be subject to involuntary redemption.

     The Funds' exchange privilege is not intended to afford  shareholders a way
to speculate on  short-term  movements in the market.  Accordingly,  in order to
prevent excessive use of the exchange privilege that may potentially disrupt the
management  of  the  Funds  and  increase  transaction  costs,  the  Funds  have
established a policy of limiting excessive  exchange activity.  Shareholders are
entitled to six (6) exchange redemptions (at least 30 days apart) from each Fund
during any twelve-month  period.  Notwithstanding  these limitations,  the Funds
reserve the right to reject any purchase request  (including  exchange purchases
from other Boston  Partners  Funds) that is deemed to be disruptive to efficient
portfolio management.

DIVIDENDS AND DISTRIBUTIONS

     Each Fund will distribute  substantially  all of its net investment  income
and net realized capital gains, if any, to its  shareholders.  All distributions
are reinvested in the form of additional full and fractional  Shares of the Fund
unless a shareholder elects otherwise.

     Each  Fund  will  declare  and pay  dividends  from net  investment  income
annually,  except the Boston  Partners  Bond Fund,  which will  declare  and pay
dividends  from net  investment  income  monthly.  Net  realized  capital  gains
(including net  short-term  capital  gains),  if any, will be distributed by the
Funds at least annually.

TAXES

     Each  Fund   contemplates   declaring  as   dividends   each  year  all  or
substantially  all of its taxable  income,  including  its net capital gain (the
excess of long-term  capital gain over short-term  capital loss).  Distributions
attributable  to the net  capital  gain  of a Fund  will  be  taxable  to you as
long-term capital gain,  regardless of how long you have held your Shares. Other
Fund  distributions  will generally be taxable as ordinary  income.  You will be
subject to income tax on Fund distributions  regardless whether they are paid in
cash or reinvested in additional  Shares.  You will be notified  annually of the
tax status of distributions to you.

     You should note that if you purchase Shares just before a distribution, the
purchase  price will  reflect the amount of the upcoming  distribution,  but you
will be taxable on the entire amount of the distribution received,  even though,
as an economic matter, the distribution simply constitutes a return of a portion
of your purchase price. This is known as "buying into a dividend."

     You will recognize  taxable gain or loss on a sale,  exchange or redemption
of your Shares,  including an exchange for Shares of another Fund,  based on the
difference  between  your tax basis in the Shares and the amount you receive for
them.  (To aid in computing  your tax basis,  you  generally  should retain your
account statements for the periods during which you held Shares.)

     Any loss  realized on Shares held for six months or less will be treated as
a long-term  capital loss to the extent of any capital gain  dividends that were
received on the Shares.

     The one major exception to these tax principles is that  distributions  on,
and  sales,  exchanges  and  redemptions  of,  Shares  held in an IRA (or  other
tax-qualified plan) will not be currently taxable.

     Shareowners  may also be subject to state and local taxes on  distributions
and  redemptions.  State income taxes may not apply however,  to the portions of
each Fund's distributions,  if any, that are attributable to interest on federal
securities  or interest on  securities  of the  particular  state or  localities
within the state.  Shareowners  should consult their tax advisers  regarding the
tax status of distributions in their state and locality.

                                       33

     The foregoing is only a summary of certain tax considerations under current
law,  which  may be  subject  to  change  in the  future.  Shareholders  who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships,  may be subject to  different  United  States  federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

MULTI-CLASS STRUCTURE

     Each Fund also offers  Institutional  Shares, which are offered directly to
institutional  investors in a separate  prospectus.  Shares of each class of the
Funds represent equal pro rata interests and accrue  dividends and calculate net
asset value and  performance  quotations in the same manner.  The performance of
each class is quoted  separately  due to different  actual  expenses.  The total
return on  Investor  Shares of a Fund can be  expected  to differ from the total
return  on  Institutional  Shares  of  the  same  Fund.  Information  concerning
Institutional  class shares of the Funds can be requested by calling the Fund at
(888) 261-4073.

INTRODUCTION TO THE RISK/RETURN SUMMARY
- --------------------------------------------------------------------------------

     This  Prospectus has been written to provide you with the  information  you
need to make an informed  decision about whether to invest in the  Institutional
Class of the Boston Partners Family of Funds of The RBB Fund, Inc.
(the "Company").

     The five mutual funds of the Company offered by this  Prospectus  represent
interests in the Boston  Partners Large Cap Value Fund,  Boston Partners Mid Cap
Value Fund,  Boston Partners Micro Cap Value Fund, Boston Partners Bond Fund and
Boston  Partners  Market  Neutral  Fund  (each a "Fund"  and  collectively,  the
"Funds").   This   Prospectus  and  the  Statement  of  Additional   Information
incorporated herein relate solely to the Funds.

     This  Prospectus  has been  organized  so that  each Fund has its own short
section with important facts about that particular Fund. Once you read the short
sections  about the Funds that  interest you, read the "Purchase of Fund Shares"
and  "Redemption of Fund Shares"  sections.  These two sections apply to all the
Funds offered by this Prospectus.

BOSTON PARTNERS LARGE CAP VALUE FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

EQUITY  SECURITY:  A  security,  such as a stock,  representing  ownership  of a
company.  Bonds,  in  comparison,  are  referred  to  as  fixed-income  or  debt
securities because they represent indebtedness to the bondholder, not ownership.

MARKET  CAPITALIZATION:  Market  capitalization  refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

VALUE  CHARACTERISTICS:  Stocks are  generally  divided into the  categories  of
"growth" or "value." Value stocks appear to the Adviser to be undervalued by the
market as measured by certain  financial  formulas.  Growth stocks appear to the
Adviser to have  earnings  growth  potential  that is greater than the market in
general,  and whose  growth in revenue is expected  to continue  for an extended
period of time.

EARNINGS GROWTH:  The increased rate of growth in a company's earnings per share
from period to period.  Security  analysts  attempt to identify  companies  with
earnings growth potential  because a pattern of earnings growth generally causes
share prices to increase.
================================================================================

INVESTMENT GOALS

     The Fund seeks to provide  long-term  growth of capital with current income
as a secondary objective.

PRIMARY INVESTMENT STRATEGIES

     The Fund invests  (during  normal  market  conditions)  at least 65% of its
total  assets  in  a  diversified   portfolio  consisting  primarily  of  equity
securities, such as common stocks and securities convertible into common stocks,
of issuers with a market  capitalization of $1 billion or greater and identified
by Boston Partners Asset  Management  L.P. (the  "Adviser") as possessing  value
characteristics.  The Fund may also  invest  up to 20% of its  total  assets  in
non-U.S. dollar denominated securities.

     The   Adviser   examines   various   factors  in   determining   the  value
characteristics  of such issuers  including price to book value ratios and price
to earnings ratios.  These value  characteristics are examined in the context of
the issuer's  operating and financial  fundamentals such as return on equity and
earnings growth and cash flow. The Adviser selects securities for the Fund based
on a continuous study of trends in industries and companies,  earnings power and
growth and other investment criteria.

     In general, the Fund's investments are broadly diversified over a number of
industries  and, as a matter of policy,  the Fund will not invest 25% or more of
its total assets in any one industry.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the policies  above,  the Fund reserves the right to hold up to
100% of its assets, as a temporary  defensive measure, in cash and eligible U.S.
dollar-denominated  money market  instruments.  The Adviser will  determine when
market conditions warrant temporary defensive measures.

KEY RISKS

     (BULLET) At least 65% of the Fund's  total  assets  will be  invested  in a
       diversified  portfolio  of equity  securities,  and the net  asset  value
       ("NAV") of the Fund will change with  changes in the market  value of its
       portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) Although the Fund will invest in stocks the Adviser believes to be
       undervalued,  there is no guarantee  that the prices of these stocks will
       not move even lower.

     (BULLET) Convertible securities frequently have speculative characteristics
       and  may  be  acquired   without  regard  to  minimum  quality   ratings.
       Convertible  securities  and  obligations  rated in the lowest of the top
       four rating  categories  are subject to greater  credit and interest rate
       risk than higher rated securities.

                                        4

<PAGE>


     (BULLET)  The  Fund  may,  for  temporary  defensive  purposes,   invest  a
       percentage of its total assets,  without  limitation,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market  instruments tends to fall when current interest rates rise. Money
       market  instruments are generally less sensitive to interest rate changes
       than longer-term securities. When the Fund's assets are invested in these
       instruments, the Fund may not be achieving its investment objective.

     (BULLET)  International  investing is subject to special risks,  including,
       but not limited to, currency exchange rate volatility,  political, social
       or economic instability,  and differences in taxation, auditing and other
       financial practices.

     (BULLET) The Fund may experience  relatively large purchases or redemptions
       due to  asset  allocation  decisions  made  by the  Adviser  for  clients
       receiving  asset  allocation   account   management   services  involving
       investments in the Fund. These transactions may have a material effect on
       the Fund, since  redemptions  caused by  reallocations  may result in the
       Fund selling portfolio  securities it might not otherwise sell, resulting
       in  a  higher   portfolio   turnover  rate,   and  purchases   caused  by
       reallocations may result in the Fund receiving  additional cash that will
       remain  uninvested  until  additional  securities  can be purchased.  The
       Adviser will attempt to minimize the effects of these transactions at all
       times.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets  generally.

PRIOR PERFORMANCE
     ANNUAL TOTAL RETURNS AS OF  DECEMBER 31
     The bar chart below shows the  variability  of the annual total returns for
the  Institutional  Class of the Fund for the last two calendar  years.  The bar
chart provides some  indication of the risks of investing in the Fund by showing
changes in the performance of the Fund's  Institutional Class from year to year.
Past performance is not necessarily an indicator of how the Fund will perform in
the future.

<PAGE>

     Since  inception  (January 2, 1997),  the highest  calendar  quarter  total
return for the  Institutional  Class of the Fund was 15.39%  (quarter ended June
30, 1997) and the lowest  calendar  quarter  total return was (16.02)%  (quarter
ended  September  30,  1998).  The total return was (10.93)% for the nine months
ended September 30, 1999.

     AVERAGE ANNUAL TOTAL RETURNS -- COMPARISON

     The table below shows how the Fund's  average  annual total returns for the
past one calendar year and since  inception,  with respect to the  Institutional
Class,  compare with the Standard & Poor's 500 Composite  Stock Price Index (the
"S&P 500 Index") for the same periods.  The S&P 500 Index is an unmanaged  index
composed  of 500 common  stocks,  most of which are listed on the New York Stock
Exchange.  The S&P 500 Index assigns  relative  values to the stocks included in
the index,  weighted  accordingly to each stock's total market value relative to
the total  market value of the other  stocks  included in the index.  The table,
like the bar chart,  provides  some  indication of the risks of investing in the
Fund by showing how the Fund's average annual total returns for 1 year and since
inception  compare  with those of a broad  measure of market  performance.  Past
performance is not  necessarily an indicator of how the Fund will perform in the
future.

EXPENSES AND FEES

     Fund investors pay various  expenses,  either  directly or indirectly.  The
purpose of the following  table and example is to describe the fees and expenses
that you may pay if you buy and hold  shares of the  Institutional  Class of the
Fund. The table is based on expenses for the Institutional Class of the Fund for
the most recent fiscal year ended August 31, 1999.

     (1) "Other  expenses"  include  audit,   administration,   custody,  legal,
         registration,  transfer agency and miscellaneous  other charges for the
         Institutional Class.

     (2) The Adviser  has agreed that until  December  31,  2000,  it will waive
         advisory  fees and  reimburse  expenses to the extent that total annual
         Fund operating expenses exceed 1.00%.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Institutional  Class of the Fund  with the  cost of  investing  in other  mutual
funds. The example assumes that you invest $10,000 in the Institutional Class of
the Fund for the time  periods  indicated  and then redeem all of your shares at
the end of each period.  The example also assumes that your  investment has a 5%
return each year and that the operating  expenses of the Institutional  Class of
the Fund  remain the same,  except for the  expiration  of the fee  waivers  and
reimbursements on December 31, 2000. Although your actual costs may be higher or
lower, based on these assumptions your cost would be:

              1 YEAR        3 YEARS        5 YEARS       10 YEARS

BOSTON PARTNERS MID CAP VALUE FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

EQUITY  SECURITY:  A  security,  such as a stock,  representing  ownership  of a
company.  Bonds,  in  comparison,  are  referred  to  as  fixed-income  or  debt
securities because they represent indebtedness to the bondholder, not ownership.

MARKET  CAPITALIZATION:  Market  capitalization  refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

VALUE  CHARACTERISTICS:  Stocks are  generally  divided into the  categories  of
"growth" or "value." Value stocks appear to the Adviser to be undervalued by the
market as measured by certain  financial  formulas.  Growth stocks appear to the
Adviser to have  earnings  growth  potential  that is greater than the market in
general,  and whose  growth in revenue is expected  to continue  for an extended
period of time.

EARNINGS GROWTH:  The increased rate of growth in a company's earnings per share
from period to period.  Security  analysts  attempt to identify  companies  with
earnings growth potential  because a pattern of earnings growth generally causes
share prices to increase.
======================

INVESTMENT GOALS

     The Fund seeks to provide  long-term  growth of capital  primarily  through
investment in equity securities. Current income is a secondary goal.

PRIMARY INVESTMENT STRATEGIES

     The Fund pursues its goal by investing,  under normal market conditions, at
least 65% of its total assets in a diversified portfolio consisting primarily of
equity securities, such as common stocks of issuers with a market capitalization
of between $200 million and $6 billion and  identified by Boston  Partners Asset
Management L.P.(the "Adviser") as having value characteristics.

     The   Adviser   examines   various   factors  in   determining   the  value
characteristics  of such issuers  including price to book value ratios and price
to earnings ratios.  These value  characteristics are examined in the context of
the issuer's operating and financial  fundamentals such as return on equity, and
earnings growth and cash flow. The Adviser selects securities for the Fund based
on a continuous study of trends in industries and companies,  earnings power and
growth and other investment criteria.

     The  Fund  may  also  invest  up to 20% of its  total  assets  in non  U.S.
dollar-denominated securities.

     In general, the Fund's investments are broadly diversified over a number of
industries  and,  as a matter of  policy,  the Fund is limited  to  investing  a
maximum of 25% of its total assets in any one industry.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the  above-mentioned  policies,  the Fund reserves the right to
hold up to 100% of its assets,  as a temporary  defensive  measure,  in cash and
eligible  U.S.  dollar-denominated  money market  instruments.  The Adviser will
determine when market conditions warrant temporary defensive measures.

KEY RISKS

     (BULLET) At least 65% of the Fund's  total  assets will be  invested  under
       normal market conditions in a diversified portfolio of equity securities,
       and the net asset value  ("NAV") of the Fund will change with  changes in
       the market value of its portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET)  The  Fund  may,  for  temporary  defensive  purposes,   invest  a
       percentage of its total assets,  without  limitation,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market  instruments tends to fall when current interest rates rise. Money
       market  instruments are generally less sensitive to interest rate changes
       than longer-term securities. When the Fund's assets are invested in these
       instruments, the Fund may not be achieving its investment objective.

                                        9
<PAGE>

     (BULLET) Although the Fund will invest in stocks the Adviser believes to be
       undervalued,  there is no guarantee  that the prices of these stocks will
       not move even lower.

     (BULLET) International  investing is  subject to special risks,  including,
       but not limited to, currency exchange rate volatility,  political, social
       or economic instability,  and differences in taxation, auditing and other
       financial practices.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

     ANNUAL TOTAL RETURNS AS OF DECEMBER 31

     The bar chart below shows the total return for the  Institutional  Class of
the  Fund  during  its  first  full  calendar  year.  Past  performance  is  not
necessarily an indicator of how the Fund will perform in the future.

     Since inception (June 2, 1997),  the highest  calendar quarter total return
for the  Institutional  Class of the Fund was 13.55%  (quarter  ended  March 31,
1998) and the lowest calendar  quarter total return was (20.90)%  (quarter ended
September  30,  1998).  The total  return was (10.20)% for the nine months ended
September 30, 1999.

     AVERAGE ANNUAL TOTAL RETURNS -- COMPARISON

     The table below shows how the Fund's  average  annual total returns for the
past one calendar year and since  inception,  with respect to the  Institutional
Class,  compare  with the Russell 2500 Index for the same  periods.  The Russell
2500 Index is an  unmanaged  index  (with no defined  investment  objective)  of
common stocks,  includes reinvestment of dividends and is a registered trademark
of the Frank Russell Corporation.  The table, like the bar chart,  provides some
indication  of the risks of  investing  in the Fund by  showing  how the  Fund's
average annual total returns for 1 year and since  inception  compare with those
of a broad measure of market performance. Past performance is not necessarily an
indicator of how the Fund will perform in the future.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Institutional  Class of the Fund  with the  cost of  investing  in other  mutual
funds. The example assumes that you invest $10,000 in the Institutional Class of
the Fund for the time  periods  indicated  and then redeem all of your shares at
the end of each period.  The example also assumes that your  investment has a 5%
return each year and that the operating  expenses of the Institutional  Class of
the Fund  remain the same,  except for the  expiration  of the fee  waivers  and
reimbursements on December 31, 2000. Although your actual costs may be higher or
lower, based on these assumptions your cost would be:

              1 YEAR        3 YEARS        5 YEARS       10 YEARS
              ------        -------        -------       --------

BOSTON PARTNERS MICRO CAP VALUE FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

EQUITY  SECURITY:  A  security,  such as a stock,  representing  ownership  of a
company.  Bonds,  in  comparison,  are  referred  to  as  fixed-income  or  debt
securities because they represent indebtedness to the bondholder, not ownership.

MARKET  CAPITALIZATION:  Market  capitalization  refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

VALUE  CHARACTERISTICS:  Stocks are  generally  divided into the  categories  of
"growth" or "value." Value stocks appear to the Adviser to be undervalued by the
market as measured by certain  financial  formulas.  Growth stocks appear to the
Adviser to have  earnings  growth  potential  that is greater than the market in
general,  and whose  growth in revenue is expected  to continue  for an extended
period of time.

EARNINGS GROWTH:  The increased rate of growth in a company's earnings per share
from period to period.  Security  analysts  attempt to identify  companies  with
earnings growth potential  because a pattern of earnings growth generally causes
share prices to increase.

ADRS AND  EDRS:  Receipts  typically  issued  by a United  States  bank or trust
company evidencing ownership of underlying foreign securities.
================================================================================

INVESTMENT GOALS

     The Fund seeks long-term growth of capital primarily through  investment in
equity securities. Current income is a secondary objective.

PRIMARY INVESTMENT STRATEGIES

     The Fund pursues its goal by investing,  under normal market conditions, at
least 65% of its total assets in a diversified portfolio consisting primarily of
equity securities of issuers with market capitalizations that do not exceed $500
million  when  purchased by the Fund and  identified  by Boston  Partners  Asset
Management L.P. (the "Adviser") as having value characteristics.

     The Fund generally invests in the equity securities of small companies. The
Adviser  will seek to invest in companies it considers to be well managed and to
have attractive  fundamental  financial  characteristics.  The Adviser  believes
greater potential for price appreciation exists among small companies since they
tend to be less widely  followed by other  securities  analysts  and thus may be
more likely to be  undervalued  by the market.  The Fund may invest from time to
time a portion of its assets, not to exceed 35% (under normal conditions) at the
time of purchase, in companies with considerably larger market capitalizations.

      The  Adviser   examines   various   factors  in   determining   the  value
characteristics  of such issuers  including price to book value ratios and price
to earnings ratios.  These value  characteristics are examined in the context of
the issuer's  operating  and  financial  fundamentals  such as return on equity,
earnings growth and cash flow. The Adviser selects securities for the Fund based
on a fundamental analysis of industries and companies, earnings power and growth
and other investment criteria.

     The Fund may invest up to 25% of its total assets in equity  securities  of
foreign issuers,  including American  Depository  Receipts ("ADRs") and European
Depository Receipts ("EDRs").

     In general, the Fund's investments are broadly diversified over a number of
industries  and,  as a matter of  policy,  the Fund is limited  to  investing  a
maximum of 25% of its total assets in any one industry.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the  above-mentioned  policies,  the Fund reserves the right to
hold up to 100% of its assets,  as a temporary  defensive  measure,  in cash and
eligible  U.S.  dollar-denominated  money market  instruments.  The Adviser will
determine when market conditions warrant temporary defensive measures.

                                       14

<PAGE>

KEY RISKS

     (BULLET) At least 65% of the Fund's  total  assets  will be  invested  in a
       diversified  portfolio  of equity  securities,  and the net  asset  value
       ("NAV") of the Fund will change with  changes in the market  value of its
       portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) Although the Fund will invest in stocks the Adviser believes to be
       undervalued,  there is no guarantee  that the prices of these stocks will
       not move even lower.

     (BULLET) The Fund will invest in smaller  issuers  which are more  volatile
       than  investments  in issuers with a market  capitalization  greater than
       $500 million.  Small market capitalization issuers are not as diversified
       in their  business  activities as issuers with market values greater than
       $500 million and are more susceptible to changes in the business cycle.

     (BULLET) The equity  securities  in  which the Fund  invests  will often be
       traded only in the  over-the-counter  market or on a regional  securities
       exchange,  may be listed only in the quotation  service commonly known as
       the  "pink  sheets,"  and may not be traded  every  day or in the  volume
       typical  of  trading  on a national  securities  exchange.  These  equity
       securities may also be subject to wide  fluctuations in market value. The
       trading market for any given equity security may be sufficiently small as
       to make it difficult  for the Fund to dispose of a  substantial  block of
       such equity securities.  The sale by the Fund of portfolio  securities to
       meet  redemptions  may  require  the Fund to sell these  securities  at a
       discount  from market  prices or during  periods  when,  in the Adviser's
       judgement, such sale is not desirable. Moreover, the lack of an efficient
       market for these securities may make them difficult to value.

     (BULLET) International  investing is subject  to special risks,  including,
       but not limited to, currency exchange rate volatility,  political, social
       or economic instability,  and differences in taxation, auditing and other
       financial practices.

     (BULLET) If the Fund frequently trades its portfolio  securities,  the Fund
       will incur higher  brokerage  commissions  and transaction  costs,  which
       could lower the Fund's  performance.  In  addition to lower  performance,
       high portfolio turnover could result in taxable capital gains. The annual
       portfolio  turnover  rate for the Fund is not  expected  to exceed  150%,
       however,  it may be higher if the Adviser  believes  it will  improve the
       Fund's performance.

     (BULLET) The  Fund  may,  for  temporary  defensive  purposes,   invest   a
       percentage of its total assets,  without  limitation,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market  instruments tends to fall when current interest rates rise. Money
       market  instruments are generally less sensitive to interest rate changes
       than longer-term securities. When the Fund's assets are invested in these
       instruments, the Fund may not be achieving its investment objective.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

EXPENSES AND FEES

     Fund investors pay various  expenses,  either  directly or indirectly.  The
purpose of the following  table and example is to describe the fees and expenses
that you may pay if you buy and hold  shares of the  Institutional  Class of the
Fund. The table is based upon expenses for the  Institutional  Class of the Fund
for the most recent fiscal year ended August 31, 1999.

                                                             -------------------
     SHAREHOLDER FEES (fees paid directly from your investment)
     Maximum sales charge imposed on purchases .................     None
     Maximum deferred sales charge .............................     None
     Maximum sales charge imposed on reinvested dividends ......     None
     Redemption Fee(1) .........................................      1.00%
     Exchange Fee ..............................................     None

     ANNUAL FUND OPERATING EXPENSES (expenses that are deducted
     from Fund assets)

     Management fees ...........................................     1.25%
     Distribution (12b-1) fees .................................     None
     Other expenses(2) .........................................    16.59%
                                                                    -----
         Total annual Fund operating expenses ..................    17.84%
     Fee waivers and expense reimbursements(3) .................    16.29%
                                                                    -----
     Net expenses ..............................................     1.55%
                                                                    =====

     (1) To prevent the Fund from being  adversely  affected by the  transaction
         costs  associated with short-term  shareholder  transactions,  the Fund
         will  redeem  shares  at a price  equal to the net  asset  value of the
         shares,  less an additional  transaction  fee equal to 1.00% of the net
         asset  value of all such shares  redeemed  that have been held for less
         than one year.  Such fees are not sales charges or contingent  deferred
         sales  charges,  but  are  retained  by the  Fund  for the  benefit  of
         remaining shareholders.

     (2) "Other  expenses"  include  audit,   administration,   custody,  legal,
         registration,  transfer agency and miscellaneous  other charges for the
         Institutional Class.

     (3) The Adviser  has agreed that until  December  31,  2000,  it will waive
         advisory  fees and  reimburse  expenses to the extent that total annual
         Fund operating expenses exceed 1.55%.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Institutional  Class of the Fund  with the  cost of  investing  in other  mutual
funds. The example assumes that you invest $10,000 in the Institutional Class of
the Fund for the time  periods  indicated  and then redeem all of your shares at
the end of each period.  The example also assumes that your  investment has a 5%
return each year and that the operating  expenses of the Institutional  Class of
the Fund  remain the same,  except for the  expiration  of the fee  waivers  and
reimbursements on December 31,2000.  Although your actual costs may be higher or
lower, based on these assumptions your cost would be:

               1 YEAR        3 YEARS        5 YEARS       10 YEARS
               ------        -------        -------       --------
                $158         $3,390         $5,846         $9,704

FINANCIAL HIGHLIGHTS

     The table below sets forth certain  financial  information  for the periods
indicated,  including per share information results for a single Fund share. The
term "Total Return"  indicates how much your investment  would have increased or
decreased  during this period of time and assumes that you have  reinvested  all
dividends and  distributions.  This information has been derived from the Fund's
financial  statements  audited  by  PricewaterhouseCoopers  LLP,  the  Company's
independent accountants. This information should be read in conjunction with the
Fund's  financial  statements  which,  together  with the report of  independent
accountants,  are included in the Fund's annual report,  which is available upon
request (see back cover for ordering instructions).

================================================================================
                              IMPORTANT DEFINITIONS

TOTAL RETURN:  A way of measuring Fund  performance.  Total return is based on a
calculation that takes into account income dividends, capital gain distributions
and the increase or decrease in share price.

FIXED-INCOME SECURITIES:  Fixed-income securities are generally bonds, which are
a type of  security  that  functions  like a loan.  Bonds are  "IOUs"  issued by
private companies,  municipalities or government agencies.  By comparison,  when
you buy a stock, you are buying ownership in a company. With a bond, your "loan"
is for a specific  period,  usually 5 to 30 years.  You receive regular interest
payments at a fixed rate. Hence the term "fixed-income" security.

INVESTMENT-GRADE FIXED-INCOME SECURITIES: Securities which are rated at the time
of  purchase  "AAA,"  "AA," "A," or "BBB" by S&P,  "Aaa,"  "Aa," "A" or "Baa" by
Moody's or which are  similarly  rated by  another  Rating  Organization  or are
unrated but deemed by the  Adviser to be  comparable  in quality to  instruments
that are so rated.  Debt securities  rated "BBB" by S&P, "Baa" by Moody's or the
equivalent   rating  of  another   Rating   Organization,   while  still  deemed
investment-grade,  are considered to have  speculative  characteristics  and are
more sensitive to economic change than higher rated bonds.

CORPORATE DEBT OBLIGATIONS: A long-term bond issued by a corporation,  including
railroads and public utilities.

MORTGAGE-BACKED  SECURITIES:  Pools  of  mortgage  loans  assembled  for sale to
investors by various governmental agencies as well as by private issuers.

ASSET-BACKED SECURITIES: Pools of assets, usually loans such as installment sale
contracts or credit card receivables, assembled for sale by private issuers.

MATURITY:  The date on which an investor in a fixed income security will be paid
in full by the issuer.
================================================================================

INVESTMENT GOALS

     The Fund  seeks to  maximize  total  return  by  investing  principally  in
investment grade fixed-income securities. Current income is a secondary goal.

PRIMARY INVESTMENT STRATEGIES

     The Fund invests  (during  normal  market  conditions)  at least 75% of its
total assets in bonds,  including corporate debt obligations and mortgage-backed
and   asset-backed   securities   (collectively,    "Debt   Securities")   rated
investment-grade  or better at the time of purchase by Standard & Poor's Ratings
Group  ("S&P") or  Moody's  Investors  Service,  Inc.  ("Moody's")  or which are
similarly rated by another nationally recognized statistical rating organization
("Rating  Organization").  The Fund may also purchase Debt Securities  which are
unrated but deemed by Boston  Partners Asset  Management L.P. (the "Adviser") to
be comparable in quality to investment-grade instruments. The Fund may invest up
to 25% of its total assets in Debt  Securities  rated "Ba" and "B" by Moody's or
"BB" and "B" by S&P or which are similarly rated by another Rating  Organization
(i.e.,  high  yield,  high risk  securities)  or are  unrated  but deemed by the
Adviser to be comparable in quality to instruments that are so rated.

KEY RISKS

     (BULLET) The net asset value  ("NAV") of the Fund will change with  changes
       in the market value of its portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) The Fund is subject to interest rate risk.  Rising  interest rates
       cause the prices of  fixed-income  securities  to  decrease  and  falling
       interest rates cause the prices of  fixed-income  securities to increase.
       Securities with longer  maturities can be more sensitive to interest rate
       changes.  In effect,  the longer the maturity of a security,  the greater
       the impact a change in interest rates could have on the security's price.

     (BULLET) High yield, high risk fixed-income  securities have a greater risk
       of default in the payment of interest  and  principal  than higher  rated
       securities and are subject to significant changes in price. Investment by
       the Fund in such  securities  involves a high  degree of credit  risk and
       such securities are regarded as speculative by the major rating agencies.

     (BULLET) If the Fund frequently trades its portfolio  securities,  the Fund
       will incur higher  brokerage  commissions  and transaction  costs,  which
       could lower the Fund's performance. In addition to lower perfor-

                                       19

<PAGE>


       mance, high portfolio turnover could result in taxable capital gains. The
       annual  portfolio  turnover  rate for the Fund is not  expected to exceed
       100%,  however,  it may be higher if the Adviser believes it will improve
       the Fund's performance.

     (BULLET) The Fund may experience  relatively large purchases or redemptions
       due to  asset  allocation  decisions  made  by the  Adviser  for  clients
       receiving  asset  allocation   account   management   services  involving
       investments in the Fund. These transactions may have a material effect on
       the Fund, since  redemptions  caused by  reallocations  may result in the
       Fund selling portfolio  securities it might not otherwise sell, resulting
       in  a  higher   portfolio   turnover  rate,   and  purchases   caused  by
       reallocations may result in the Fund receiving  additional cash that will
       remain  uninvested  until  additional  securities  can be purchased.  The
       Adviser will attempt to minimize the effects of these transactions at all
       times.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

     ANNUAL TOTAL RETURNS AS OF DECEMBER 31

     The bar chart below shows the total return for the  Institutional  Class of
the  Fund  during  its  first  full  calendar  year.  Past  performance  is  not
necessarily an indicator of how the Fund will perform in the future.

     Since inception  (December 30, 1997),  the highest  calendar  quarter total
return  for the  Institutional  Class  of the  Fund  was  2.50%  (quarter  ended
September  30,  1998) and the lowest  calendar  quarter  total return was (.53)%
(quarter ended March 31, 1999).  The total return was (.08)% for the nine months
ended September 30, 1999.

     AVERAGE ANNUAL TOTAL RETURNS -- COMPARISON

     The table below shows how the Fund's  average  annual total returns for the
past one calendar year and since  inception,  with respect to the  Institutional
Class,  compare with the Lehman Aggregate Index for the same periods. The Lehman
Aggregate Index is an unmanaged index containing  fixed-income  securities rated
investment  grade or higher by  Moody's,  S&P or Fitch  Investors  Service.  All
issues have at least one year to  maturity  and an  outstanding  par value of at
least $100  million.  The Lehman  Aggregate  Index is a registered  trademark of
Lehman Brothers, Inc. The table, like the bar chart, provides some indication of
the risks of  investing  in the Fund by showing  how the Fund's  average  annual
total  returns  for 1 year and since  inception  compare  with  those of a broad
measure of market performance.  Past performance is not necessarily an indicator
of how the Fund will perform in the future.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Institutional  Class of the Fund  with the  cost of  investing  in other  mutual
funds. The example assumes that you invest $10,000 in the Institutional Class of
the Fund for the time  periods  indicated  and then redeem all of your shares at
the end of each period.  The example also assumes that your  investment has a 5%
return each year and that the operating  expenses of the Institutional  Class of
the Fund  remain the same,  except for the  expiration  of the fee  waivers  and
reimbursements on December 31, 2000. Although your actual costs may be higher or
lower, based on these assumptions your cost would be:

               1 YEAR        3 YEARS        5 YEARS       10 YEARS
               ------        -------        -------       --------

BOSTON PARTNERS MARKET NEUTRAL FUND
- --------------------------------------------------------------------------------

================================================================================
                              IMPORTANT DEFINITIONS

MARKET NEUTRAL: Refers to a strategy of investing or engaging in transactions in
equity  securities,  while  seeking to minimize  the impact of  movements in the
equity markets.

EQUITY  SECURITY:  A  security,  such as a stock,  representing  ownership  of a
company.  Bonds,  in  comparison,  are  referred  to  as  fixed-income  or  debt
securities because they represent indebtedness to the bondholder, not ownership.

TOTAL RETURN:  A way of measuring Fund  performance.  Total return is based on a
calculation that takes into account income dividends, capital gain distributions
and the increase or decrease in share price.

SALOMON SMITH BARNEY U.S. 1-MONTH TREASURY BILL INDEX(TRADE  MARK): An unmanaged
index  containing  monthly  return  equivalents  of yield  averages that are not
marked to market.

SHORT  SALE:  A sale by the Fund of a security  which has been  borrowed  from a
third party on the expectation  that the market price will drop. If the price of
the security  drops,  the Fund will make a profit by purchasing  the security in
the open market at a lower price than the one at which it sold the security.  If
the price of the security  rises,  the Fund may have to cover its short position
at a higher price than the short sale price, resulting in a loss.

SHORT-TERM CASH INSTRUMENTS: These temporary investments include notes issued or
guaranteed by the U.S. Government, its agencies or instrumentalities; commercial
paper  rated in the two  highest  rating  categories;  certificates  of deposit;
repurchase agreements and other high-grade corporate debt securities.

FEDERAL FUNDS RATE: The rate of interest  charged by a Federal  Reserve bank for
member banks to borrow their federally required reserve.

MARKET  CAPITALIZATION:  Market  capitalization  refers to the market value of a
company and is calculated by multiplying the number of shares outstanding by the
current price per share.

ADRS:  Receipts  typically  issued  by a United  States  bank or  trust  company
evidencing ownership of underlying foreign securities.
================================================================================

INVESTMENT GOALS

     The Fund seeks long-term capital  appreciation while minimizing exposure to
general  equity market risk.  The Fund seeks a total return greater than that of
the Salomon Smith Barney U.S. 1-Month Treasury Bill Index.(TRADE MARK)

PRIMARY INVESTMENT STRATEGIES

     The Fund invests in long positions in stocks  identified by Boston Partners
Asset  Management  L.P. (the  "Adviser") as undervalued  and short  positions in
stocks that the Adviser has  identified  as  overvalued.  The cash proceeds from
short sales will be invested in short-term cash  instruments to produce a return
on such  proceeds  just below the federal  funds  rate.  The Fund will invest in
securities  principally  traded in the United States  markets.  The Adviser will
determine  the size of each long or short  position by  analyzing  the  tradeoff
between the  attractiveness  of each  position and its impact on the risk of the
overall portfolio.  The Fund seeks to construct a portfolio that has minimal net
exposure  to the  United  States  equity  market  generally  and low to  neutral
exposure to specific industries,  specific market  capitalization  ranges (e.g.,
large cap, mid cap and small cap) and certain other factors.

     The Fund's long and short  positions  may involve  (without  limit)  equity
securities  of  foreign  issuers  that are  traded in the  markets of the United
States as sponsored American  Depository  Receipts  ("ADRs").  The Fund may also
invest up to 20% of its total assets  directly in equity  securities  of foreign
issuers.

     To meet margin requirements,  redemptions or pending investments,  the Fund
may also  temporarily  hold a portion  of its  assets in full  faith and  credit
obligations of the United States government and in short-term notes,  commercial
paper or other money market instruments.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the  above-mentioned  policies,  the Fund reserves the right to
hold up to 100% of its assets,  as a temporary  defensive  measure,  in cash and
eligible  U.S.  dollar-denominated  money market  instruments.  The Adviser will
determine when market conditions warrant temporary defensive measures.

KEY RISKS

     (BULLET) The net asset value  ("NAV") of the Fund will change with  changes
       in the market value of its portfolio positions.

     (BULLET) Investors may lose money.

     (BULLET) The Fund is subject  to the risk of poor  stock  selection  by the
       Adviser.  In  other  words,  the  Adviser  may not be  successful  in its
       strategy  of  taking  long  positions  in  undervalued  stocks  and short
       positions in overvalued  stocks.  Further,  since the Adviser will manage
       both a long and a short portfolio, there is the risk that the Adviser may
       make more poor  investment  decisions  than an adviser of a typical stock
       mutual fund with only a long portfolio may make.

     (BULLET)  Short  sales of  securities  may result in gains if a  security's
       price declines,  but may result in losses if a security's  price does not
       decline in price.

     (BULLET) The Fund could lose money if a seller under a repurchase agreement
       defaults or declares bankruptcy.

     (BULLET)  Securities held in a segregated  account cannot be sold while the
       position it is covering is  outstanding,  unless they are  replaced  with
       similar securities.  As a result, there is a possibility that segregation
       of a  large  percentage  of the  Fund's  assets  could  impede  portfolio
       management  or the Fund's  ability to meet  redemption  requests or other
       current obligations.

     (BULLET)  The  Fund  may,  for  temporary  defensive  purposes,   invest  a
       percentage of its total assets,  without limitations,  in cash or various
       U.S.  dollar-denominated  money  market  instruments.  The value of money
       market  instruments tends to fall when current interest rates rise. Money
       market  instruments are generally less sensitive to interest rate changes
       than longer-term securities. When the Fund's assets are invested in these
       instruments, the Fund may not be achieving its investment objective.

     (BULLET) The risks of international  investing include, but are not limited
       to,  currency  exchange rate  volatility,  political,  social or economic
       instability,  and  differences in taxation,  auditing and other financial
       practices.

     (BULLET) If the Fund frequently trades its portfolio  securities,  the Fund
       will incur higher  brokerage  commissions  and transaction  costs,  which
       could lower the Fund's  performance.  In  addition to lower  performance,
       high portfolio turnover could result in taxable capital gains. The annual
       portfolio  turnover  rate for the Fund is not  expected  to exceed  200%,
       however,  it may be higher if the Adviser  believes  it will  improve the
       Fund's performance.

     (BULLET) The Fund could be  affected  if the  computer  systems on which it
       relies do not properly process information  beginning on January 1, 2000.
       While Year 2000  issues  could have a  negative  effect on the Fund,  the
       Adviser is currently working to avoid such problems.  The Adviser is also
       working with the Fund's other service  providers and vendors to determine
       their  systems'  ability  to  handle  Year  2000  problems.  There  is no
       guarantee  that the systems will work  properly on January 1, 2000.  Year
       2000  problems may also hurt issuers whose  securities  the Fund holds or
       securities markets generally.

     EXPENSES AND FEES

     Fund investors pay various  expenses,  either  directly or indirectly.  The
purpose of the following  table and example is to describe the fees and expenses
that you may pay if you buy and hold  shares of the  Institutional  Class of the
Fund. The table is based on expenses for the Institutional Class of the Fund for
the period  November 17, 1998  (commencement  of operations)  through August 31,
1999.

     Net expenses ...........................................         2.95%
                                                                     =====

     (1) To prevent the Fund from being  adversely  affected by the  transaction
         costs  associated with short-term  shareholder  transactions,  the Fund
         will  redeem  shares  at a price  equal to the net  asset  value of the
         shares,  less an additional  transaction  fee equal to 1.00% of the net
         asset  value of all such shares  redeemed  that have been held for less
         than one year.  Such fees are not sales charges or contingent  deferred
         sales  charges,  but are  retained  by the Fund for the  benefit of all
         shareholders.

     (2) "Other  expenses"  include  audit,   administration,   custody,  legal,
         registration,  transfer agency and miscellaneous  other charges for the
         Institutional  Class. "Other expenses" and "Total annual Fund operating
         expenses" include dividends on securities which the Fund has sold short
         ("short-sale  dividends").  Short-sale  dividends  generally reduce the
         market value of the  securities by the amount of the dividend  declared
         -- thus  increasing the Fund's  unrealized  gain or reducing the Fund's
         unrealized loss on the securities sold short.  Short-sale dividends are
         treated as an expense,  and increase the Fund's  total  expense  ratio,
         although  no  cash is  received  or paid by the  Fund.  The  amount  of
         short-sale  dividends  is  estimated at 0.45% of average net assets for
         the current fiscal year.

     (3) The Adviser  has agreed that until  December  31,  2000,  it will waive
         advisory  fees and  reimburse  expenses to the extent that total annual
         Fund  operating  expenses  exceed 2.50%  excluding  short sale dividend
         expense.

EXAMPLE

     The example is intended  to help you compare the cost of  investing  in the
Institutional  Class of the Fund  with the  cost of  investing  in other  mutual
funds. The example assumes that you invest $10,000 in the Institutional Class of
the Fund for the time  periods  indicated  and then redeem all of your shares at
the end of each period.  The example also assumes that your  investment has a 5%
return each year and that the operating  expenses of the Institutional  Class of
the Fund  remain the same,  except for the  expiration  of the fee  waivers  and
reimbursements on December 31, 2000. Although your actual costs may be higher or
lower, based on these assumptions your cost would be:

            1 YEAR        3 YEARS        5 YEARS       10 YEARS
            ------        -------        -------       --------
             $298         $4,590         $7,245         $10,253

     The table below sets forth certain  financial  information  for the periods
indicated,  including per share information results for a single Fund share. The
term "Total Return"  indicates how much your investment  would have increased or
decreased  during this period of time and assumes that you have  reinvested  all
dividends and  distributions.  This information has been derived from the Fund's
financial  statements  audited  by  PricewaterhouseCoopers  LLP,  the  Company's
independent accountants. This information should be read in conjunction with the

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING OF FUND SHARES

     Institutional  Shares of the Funds ("Shares") are priced at their net asset
value ("NAV"). The NAV for the Institutional Class of each Fund is calculated by
adding the value of all securities, cash and other assets in a Fund's portfolio,
deducting  the Fund's actual and accrued  liabilities  and dividing by the total
number of Shares outstanding.

     Each Fund's NAV is calculated once daily at the close of regular trading on
the New York Stock Exchange ("NYSE") (currently 4:00 p.m. Eastern time) each day
the NYSE is open.  Shares  will not be  priced  on the days on which the NYSE is
closed.

     Securities  held by a Fund are valued  using the closing  price or the last
sale price on a national  securities  exchange or on the NASDAQ  National Market
System  where  they  are  traded.  If  there  were no  sales  on that day or the
securities are traded on other over-the-counter markets, the mean of the bid and
asked prices is used.  Short-term debt investments  having maturities of 60 days
or less are amortized to maturity based on their cost.  With the approval of the
Company's  Board  of  Directors,  a Fund  may  use a  pricing  service,  bank or
broker-dealer  experienced in providing valuations to value a Fund's securities.
If market quotations are unavailable, securities will be valued at fair value as
determined  in good faith by the  investment  adviser  according  to  procedures
adopted by the Company's Board of Directors.

PURCHASE OF FUND SHARES

     Shares  representing  interests in the Funds are offered  continuously  for
sale by  Provident  Distributors,  Inc.  (the  "Distributor").  You may purchase
Shares of each Fund at the NAV per share  next  calculated  after  your order is
received by PFPC Inc. (the "Transfer  Agent") in proper form as described below.
After an initial purchase is made, the Transfer Agent will set up an account for
you on RBB's records. The minimum initial investment in any Fund is $100,000 and
the minimum additional investment is $5,000. For purposes of meeting the minimum
initial purchase, purchases by clients which are part of endowments, foundations
or other related  groups may be combined.  You can only purchase  Shares of each
Fund on days the NYSE is open and through the means described below.  Shares may
be purchased by principals and employees of the Adviser and by their spouses and
children either directly or through any trust that has the principal,  employee,
spouse  or child  as the  primary  beneficiaries,  their  individual  retirement
accounts,  or any pension and  profit-sharing  plan of the Adviser without being
subject to the minimum investment limitations.

     INITIAL  INVESTMENT  BY MAIL.  An account may be opened by  completing  and
signing the  application  included  with this  Prospectus  and mailing it to the
Transfer  Agent at the address  noted  below,  together  with a check  ($100,000
minimum)  payable  to the Fund in which you would like to  invest.  Third  party
checks will not be accepted.

     BOSTON PARTNERS [NAME OF FUND]
     c/o PFPC Inc.
     P.O. Box 8852
     Wilmington, DE 19899-8852

     The  name  of  the  Fund  to be  purchased  should  be  designated  on  the
application  and should appear on the check.  Payment for the purchase of Shares
received  by mail will be  credited  to a  shareholder's  account at the NAV per
share of the Fund next determined after receipt of payment in good order.

                                       31

<PAGE>

     INITIAL  INVESTMENT BY WIRE. Shares of each Fund may be purchased by wiring
federal funds to PNC Bank (see instructions below). A completed application must
be  forwarded to the Transfer  Agent at the address  noted above under  "Initial
Investment by Mail" in advance of the wire. For each Fund,  notification must be
given to the Transfer Agent at (888) 261-4073 prior to 4:00 p.m.,  Eastern time,
on the wire date. (Prior  notification must also be received from investors with
existing accounts.) Funds should be wired to:

     PNC Bank, NA
     Philadelphia, Pennsylvania 19103
     ABA# 0310-0005-3
     Account # 86-1108-2507
     F/B/O BOSTON PARTNERS [NAME OF FUND]
     Ref. (Account Number)

     Federal  funds  purchases  will be accepted only on a day on which the NYSE
and PNC Bank, NA are open for business.

     ADDITIONAL  INVESTMENTS.  Additional  investments  may be made at any  time
(minimum investment $5,000) by purchasing Shares of any Fund at NAV by mailing a
check to the Transfer Agent at the address noted above under "Initial Investment
by Mail" (payable to Boston  Partners [name of Fund]) or by wiring monies to PNC
Bank, NA as outlined  above under  "Initial  Investment by Wire." For each Fund,
notification must be given to the Transfer Agent at (888) 261-4073 prior to 4:00
p.m., Eastern time, on the wire date.  Initial and additional  purchases made by
check cannot be redeemed until payment of the purchase has been collected.

     AUTOMATIC  INVESTMENT PLAN.  Additional  investments in Shares of the Funds
may be made  automatically  by authorizing  the Transfer Agent to withdraw funds
from your bank account through an Automatic  Investment  Plan ($5,000  minimum).
Investors  desiring to participate in an Automatic  Investment  Plan should call
the Transfer Agent at (888) 261-4073 to obtain the appropriate forms.

     OTHER PURCHASE  INFORMATION.  The Company  reserves the right,  in its sole
discretion, to suspend the offering of Shares or to reject purchase orders when,
in the  judgment of  management,  such  suspension  or  rejection is in the best
interests of the Funds. As of the date of this  Prospectus,  the Boston Partners
Micro Cap Value Fund  intends to suspend the  offering of Shares upon the Fund's
attaining $300 million in total assets.

REDEMPTION OF FUND SHARES

     You may  redeem  Shares  of the  Funds at the next NAV  calculated  after a
redemption  request is received by the Transfer  Agent in proper  form.  You can
only  redeem  Shares on days the NYSE is open and  through  the means  described
below.

     You may redeem Shares of each Fund by mail, or, if you are  authorized,  by
telephone.  The value of Shares  redeemed  may be more or less than the purchase
price,  depending on the market  value of the  investment  securities  held by a
Fund.  There is no charge for a redemption.  However,  if a  shareholder  of the
Boston Partners Market Neutral, or Boston Partners Micro Cap Value Funds redeems
Shares held for less than 1 year, a transaction fee of 1% of the net asset value
of the Shares redeemed at the time of redemption  will be charged.  For purposes
of this  redemption  feature,  shares  purchased  first will be considered to be
shares first redeemed.

                                       32

<PAGE>

     REDEMPTION BY MAIL. Your redemption  requests should be addressed to BOSTON
PARTNERS [name of Fund], c/o PFPC Inc., P.O. Box 8852, Wilmington, DE 19899-8852
and must include:

     a.  a letter  of  instruction  specifying  the  number  of shares or dollar
         amount to be redeemed, signed by all registered owners of the shares in
         the exact names in which they are registered;

     b.  any required  signature  guarantees,  which are  required  when (i) the
         redemption  request  proceeds are to be sent to someone  other than the
         registered shareholder(s) or (ii) the redemption request is for $10,000
         or more. A signature  guarantee may be obtained from a domestic bank or
         trust company,  broker, dealer,  clearing agency or savings association
         who  are  participants  in  a  Medallion  Program   recognized  by  the
         Securities  Transfer   Association.   The  three  recognized  Medallion
         Programs are Securities Transfer Agent Medallion Program (STAMP), Stock
         Exchanges  Medallion  Program (SEMP) and New York Stock Exchange,  Inc.
         Medallion Program (MSP). Signature Guarantees,  which are not a part of
         these programs, will not be accepted.  Please note that a notary public
         stamp or seal is not acceptable; and

     c.  other supporting legal documents,  if required, in the case of estates,
         trusts, guardianships, custodianships, corporations, pension and profit
         sharing plans and other organizations.

     REDEMPTION BY TELEPHONE.  In order to request a telephone  redemption,  you
must have returned your account application  containing a telephone election. To
add a telephone  redemption option to an existing account,  contact the Transfer
Agent by calling (888) 261-4073 for a Telephone Authorization Form.

     Once you are  authorized  to utilize the  telephone  redemption  option,  a
redemption  of Shares may be requested  by calling the  Transfer  Agent at (888)
261-4073 and requesting  that the  redemption  proceeds be mailed to the primary
registration address or wired per the authorized instructions.  If the telephone
redemption  option or the  telephone  exchange  option (as  described  below) is
authorized, the Transfer Agent may act on telephone instructions from any person
representing himself or herself to be a shareholder and believed by the Transfer
Agent to be genuine.  The  Transfer  Agent's  records of such  instructions  are
binding and  shareholders,  not the Company or the Transfer Agent, bear the risk
of loss in the event of  unauthorized  instructions  reasonably  believed by the
Company or the  Transfer  Agent to be genuine.  The  Transfer  Agent will employ
reasonable procedures to confirm that instructions communicated are genuine and,
if it  does  not,  it may be  liable  for  any  losses  due to  unauthorized  or
fraudulent  instructions.  The  procedures  employed  by the  Transfer  Agent in
connection with  transactions  initiated by telephone  include tape recording of
telephone instructions and requiring some form of personal  identification prior
to acting upon instructions received by telephone.

     TRANSACTION  FEE ON  CERTAIN  REDEMPTIONS  OF THE  BOSTON  PARTNERS  MARKET
NEUTRAL, AND BOSTON PARTNERS MICRO CAP VALUE FUNDS

     The Boston  Partners  Micro Cap Value and Boston  Partners  Market  Neutral
Funds require the payment of a transaction fee on redemptions of Shares held for
less than one year equal to 1.00% of the net asset value of such Shares redeemed
at the time of redemption. This additional transaction fee is paid to each Fund,
NOT to the adviser, distributor or transfer agent. It is NOT a sales charge or a
contingent deferred sales charge. The fee does not apply to redeemed Shares that
were purchased through reinvested  dividends or capital gain distributions.  The
purpose of the additional  transaction fee is to indirectly allocate transaction
costs associated with redemptions to those investors  making  redemptions  after
holding their shares for a short period, thus protecting existing  shareholders.
These costs include:  (1) brokerage  costs; (2) market impact costs -- i.e., the
decrease in market prices which may result when a Fund sells certain  securities
in order to raise cash to meet the redemption  request;  (3) the  realization of
capital gains by the other  shareholders in each Fund; and (4) the effect of the
"bid-ask" spread in the  over-the-counter  market.  The 1.00% amount  represents
each Fund's estimate of the brokerage and other  transaction  costs which may be
incurred  by each Fund in  disposing  of stocks in which  each Fund may  invest.
Without the additional transaction fee, each Fund would generally be selling its
shares at a price  less than the cost to each Fund of  acquiring  the  portfolio
securities

                                       33

<PAGE>

necessary  to maintain  its  investment  characteristics,  resulting  in reduced
investment  performance for all  shareholders in the Funds.  With the additional
transaction  fee, the  transaction  costs of selling  additional  stocks are not
borne by all existing  shareholders,  but the source of funds for these costs is
the  transaction fee paid by those  investors  making  redemptions of the Boston
Partners Micro Cap Value and Boston Partners Market Neutral Funds.

     INVOLUNTARY  REDEMPTION.  The  Company  reserves  the  right  to  redeem  a
shareholder's account in any Fund at any time the net asset value of the account
in such Fund  falls  below  $500 as the result of a  redemption  or an  exchange
request.  Shareholders  will be  notified  in  writing  that the  value of their
account  in a Fund  is less  than  $500  and  will  be  allowed  30 days to make
additional  investments before the redemption is processed.  The transaction fee
applicable to the Boston  Partners  Market Neutral and Boston Partners Micro Cap
Value Funds will not be charged when shares are involuntarily redeemed.

     OTHER REDEMPTION  INFORMATION.  Redemption proceeds for Shares of the Funds
recently  purchased  by  check  may not be  distributed  until  payment  for the
purchase has been collected, which may take up to fifteen days from the purchase
date. Shareholders can avoid this delay by utilizing the wire purchase option.

     Other than as described above,  payment of the redemption  proceeds will be
made within seven days after receipt of an order for a  redemption.  The Company
may suspend the right of  redemption or postpone the date at times when the NYSE
is closed or under any emergency circumstances as determined by the SEC.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining shareholders of the Funds to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind distribution of readily marketable  securities held by a Fund instead of
cash in conformity with applicable  rules of the SEC.  Investors  generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The Funds have elected, however, to be governed by Rule
18f-1  under the 1940 Act,  so that a Fund is  obligated  to redeem  its  Shares
solely in cash up to the lesser of $250,000 or 1% of its net asset value  during
any 90-day period for any one shareholder of a Fund.

EXCHANGE PRIVILEGE

     The exchange  privilege is available to shareholders  residing in any state
in which the Shares  being  acquired  may be legally  sold.  A  shareholder  may
exchange  Institutional  Shares of any Boston  Partners  Fund for  Institutional
Shares of  another  Boston  Partners  Fund,  up to six (6) times per year.  Such
exchange will be effected at the net asset value of the exchanged  Institutional
Shares and the net asset value of the  Institutional  Shares to be acquired next
determined  after PFPC's  receipt of a request for an  exchange.  An exchange of
Boston  Partners Micro Cap Value or Boston  Partners  Market Neutral Shares held
for less than 1 year (with the exception of Shares  purchased  through  dividend
reinvestment or the  reinvestment of capital gains) will be subject to the 1.00%
transaction  fee.  An  exchange  of Shares will be treated as a sale for federal
income tax  purposes.  A  shareholder  may make an exchange by sending a written
request to the Transfer Agent or, if authorized,  by telephone (see  "Redemption
by Telephone" above).

     If the exchanging  shareholder does not currently own Institutional  Shares
of the Fund whose Shares are being  acquired,  a new account will be established
with the same  registration,  dividend  and capital  gain options as the account
from which shares are exchanged,  unless  otherwise  specified in writing by the
shareholder  with all  signatures  guaranteed.  See  "Redemption  By  Mail"  for
information on signature  guarantees.  The exchange privilege may be modified or
terminated  at any time,  or from time to time,  by the  Company,  upon 60 days'
written notice to shareholders.

     If an exchange is to a new account in a Fund  advised by the  Adviser,  the
dollar value of the Shares  acquired must equal or exceed the Fund's minimum for
a new account; if to an existing account,  the dollar value must equal or exceed
the Fund's minimum for additional investments.  If an amount remains in the Fund
from which the  exchange is being made that is below the minimum  account  value
required, the account will be subject to involuntary redemption.

                                       34

<PAGE>

     The Funds' exchange privilege is not intended to afford  shareholders a way
to speculate on  short-term  movements in the market.  Accordingly,  in order to
prevent excessive use of the exchange privilege that may potentially disrupt the
management  of  the  Funds  and  increase  transaction  costs,  the  Funds  have
established a policy of limiting excessive  exchange activity.  Shareholders are
entitled to six (6) exchange redemptions (at least 30 days apart) from each Fund
during any twelve-month  period.  Notwithstanding  these limitations,  the Funds
reserve the right to reject any purchase request  (including  exchange purchases
from other Boston  Partners  Funds) that is deemed to be disruptive to efficient
portfolio management.

DIVIDENDS AND DISTRIBUTIONS

     Each Fund will distribute  substantially  all of its net investment  income
and net realized capital gains, if any, to its  shareholders.  All distributions
are reinvested in the form of additional full and fractional  Shares of the Fund
unless a shareholder elects otherwise.

     Each  Fund  will  declare  and pay  dividends  from net  investment  income
annually,  except the Boston  Partners  Bond Fund,  which will  declare  and pay
dividends  from net  investment  income  monthly.  Net  realized  capital  gains
(including net  short-term  capital  gains),  if any, will be distributed by the
Funds at least annually.

TAXES

     Each  Fund   contemplates   declaring  as   dividends   each  year  all  or
substantially  all of its taxable  income,  including  its net capital gain (the
excess of long-term  capital gain over short-term  capital loss).  Distributions
attributable  to the net  capital  gain  of a Fund  will  be  taxable  to you as
long-term capital gain,  regardless of how long you have held your Shares. Other
Fund  distributions  will generally be taxable as ordinary  income.  You will be
subject to income tax on Fund distributions  regardless whether they are paid in
cash or reinvested in additional  Shares.  You will be notified  annually of the
tax status of distributions to you.

     You should note that if you purchase Shares just before a distribution, the
purchase  price will  reflect the amount of the upcoming  distribution,  but you
will be taxable on the entire amount of the distribution received,  even though,
as an economic matter, the distribution simply constitutes a return of a portion
of your purchase price. This is known as "buying into a dividend."

     You will recognize  taxable gain or loss on a sale,  exchange or redemption
of your Shares,  including an exchange for Shares of another Fund,  based on the
difference  between  your tax basis in the Shares and the amount you receive for
them.  (To aid in computing  your tax basis,  you  generally  should retain your
account statements for the periods during which you held Shares.)

     Any loss  realized on Shares held for six months or less will be treated as
a long-term  capital loss to the extent of any capital gain  dividends that were
received on the Shares.

     The one major exception to these tax principles is that  distributions  on,
and  sales,  exchanges  and  redemptions  of,  Shares  held in an IRA (or  other
tax-qualified plan) will not be currently taxable.

     Shareowners  may also be subject to state and local taxes on  distributions
and  redemptions.  State income taxes may not apply however,  to the portions of
each Fund's distributions,  if any, that are attributable to interest on federal
securities  or interest on  securities  of the  particular  state or  localities
within the state.  Shareowners  should consult their tax advisers  regarding the
tax status of distributions in their state and locality.

     The foregoing is only a summary of certain tax considerations under current
law,  which  may be  subject  to  change  in the  future.  Shareholders  who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships,  may be subject to  different  United  States  federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

MULTI-CLASS STRUCTURE

     Each Fund also  offers  Investor  Shares,  which are  offered  directly  to
individual investors in a separate prospectus. Shares of each class of the Funds
represent equal pro rata interests and accrue  dividends and calculate net asset
value and  performance  quotations in the same manner.  The  performance of each
class is quoted separately due to different actual expenses. The total return on
Institutional  Shares of a Fund can be expected to differ from the total  return
on  Investor  Shares of the same Fund.  Information  concerning  Investor  class
shares of the Funds can be requested by calling the Fund at (888) 261-4073.

SCHNEIDER SMALL CAP VALUE FUND
- --------------------------------------------------------------------------------


INVESTMENT GOAL

     The Fund seeks  long-term  capital growth by investing  primarily in common
stocks of companies  which have  capitalizations  that are less than the largest
company in the Russell 2000 Index ("small cap  companies")  and which  Schneider
Capital Management Company (the "Adviser")  believes are undervalued.  There can
be no guarantee that the Fund will achieve its investment objective.

PRIMARY INVESTMENT STRATEGIES

     Under normal market  conditions,  at least 65% of the Fund's assets will be
invested in small cap companies  described  above. As of September 30, 1999, the
company  with the largest  market  capitalization  in the Russell 2000 Index was
$3.4 billion and the weighted  average market  capitalization  of companies that
comprised the Russell 2000 Index was $800 million.  The Russell 2000 Index is an
unmanaged index composed of the 2,000 smallest stocks in the Russell 3000 Index,
a  market  value  weighted  index  of the  3,000  largest  U.S.  publicly-traded
companies.  As of September 30, 1999,  the weighted  average  capitalization  of
companies held by the Fund was $590 million.

KEY RISKS

     (BOX)The Fund  invests  in common  stocks  which  are  subject  to  market,
          economic and business  risks that will cause their prices to fluctuate
          over time. Therefore,  the value of your investment in the Fund may go
          up and down,  sometimes rapidly and unpredictably,  and you could lose
          money.

     (BOX)Stocks  of  small  companies  may be more  volatile  than,  and not as
          readily marketable as, those of larger companies.  Small companies may
          also have limited  product lines,  markets or financial  resources and
          may be  dependent  on  relatively  small or  inexperienced  management
          groups.  Additionally,  the trading volume of small company securities
          may make them more difficult to sell than those of larger companies.

     (BOX)Value  investing  involves  the risk  that the  Fund's  investment  in
          companies whose securities are believed to be undervalued, relative to
          their  underlying  profitability,  will  not  appreciate  in  value as
          anticipated.

EXPENSES AND FEES

     As a shareholder  you pay certain fees and expenses.  Annual Fund operating
expenses are paid out of Fund assets and are reflected in the Fund's price.

     The table below describes the fees and expenses that you may pay if you buy
and hold  shares of the  Fund.  The table is based on  expenses  for the  period
September 2, 1998 through August 31, 1999.

     SHAREHOLDER FEES (FEES PAID DIRECTLY FROM YOUR INVESTMENT)

     Redemption fee 1 .........................................   1.75%

     ANNUAL FUND OPERATING EXPENSES (EXPENSES THAT ARE DEDUCTED FROM
       FUND ASSETS)

     Management Fees ..........................................   1.00%

     Distribution and Service (12b-1) fees ....................    None

     Other expenses ...........................................   2.90%
                                                                -------

     Total Annual Fund Operating Expenses .....................   3.90%

     Fee Waiver and Expense Reimbursements2 ................... (2.80)%
                                                                -------

     Net Expenses .............................................   1.10%
                                                                =======

     1.   Shares  of the Fund not  purchased  through  reinvested  dividends  or
          capital gains distributions and held less than one year are subject to
          the above redemption fee. This fee is intended to encourage  long-term
          investment in the Fund, to avoid transaction and other expenses caused
          by early  redemption,  and to  facilitate  portfolio  management.  See
          "Redemption of Fund Shares -- Transaction fee on Certain  Redemptions"
          below for more information.

     2.   The Adviser has agreed that,  until  December 31, 2000,  it will waive
          advisory  fees and  reimburse  expenses to the extent total  operating
          expenses exceed 1.10%.

     EXAMPLE:

     THIS  EXAMPLE IS INTENDED TO HELP YOU COMPARE THE COST OF  INVESTING IN THE
FUND WITH THE COST OF INVESTING IN OTHER MUTUAL FUNDS.  THE EXAMPLE ASSUMES THAT
YOU INVEST  $10,000 IN THE FUND FOR THE TIME PERIODS  INDICATED  AND THEN REDEEM
ALL OF YOUR SHARES AT THE END OF EACH PERIOD. THE EXAMPLE ALSO ASSUMES THAT YOUR
INVESTMENT  HAS A 5% RETURN  EACH YEAR AND THAT THE  FUND'S  OPERATING  EXPENSES
REMAIN THE SAME, EXCEPT FOR THE EXPIRATION OF THE FEE WAIVERS AND REIMBURSEMENTS
ON DECEMBER 31, 2000.  ALTHOUGH YOUR ACTUAL COSTS MAY BE HIGHER OR LOWER,  BASED
ON THESE ASSUMPTIONS YOUR COST WOULD BE:

                       1 YEAR     3 YEARS      5 YEARS     10 YEARS
                       ------     -------      -------     --------
                        $291       $932        $1,769       $3,945

FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------

     The table below sets forth certain  financial  information  for the periods
indicated,  including per share information results for a single Fund share. The
term "Total Return"  indicates how much your investment  would have increased or
decreased  during this period of time and assumes that you have  reinvested  all
dividends and  distributions.  This information has been derived from the Fund's
financial  statements  audited  by  PricewaterhouseCoopers  LLP,  the  Company's
independent accountants. This information should be read in conjunction with the
Fund's  financial  statements  which,  together  with the report of  independent
accountants,  are included in the Fund's annual report,  which is available upon
request (see back cover for ordering instructions).

ADDITIONAL INFORMATION ON THE FUND'S INVESTMENT OBJECTIVE AND PRINCIPAL
   STRATEGIES

     The Fund seeks  long-term  capital growth by investing  primarily in common
stocks of companies  which have  capitalizations  that are less than the largest
company  in  the  Russell  2000  Index  and  which  the  Adviser   believes  are
undervalued.  The Fund's investment  objective and the policies  described above
may be changed by RBB's Board of  Directors  without the  approval of the Fund's
shareholders.  However,  as a matter of policy,  the Fund  would not  materially
change its investment objective without notifying shareholders.

     The Adviser  selects  securities for the Fund based on a continued study of
trends in  industries  and  companies,  industry  literature,  company  reports,
financial reports,  company  presentations,  earnings power and growth and other
investment criteria.

     The Fund may invest in securities that the Adviser believes may exhibit the
following characteristics:

     (BOX)have low price-to-earnings and low price-to-book value ratios;

     (BOX)are  typically  considered  out of favor by the  market as a result of
          decelerating  revenue growth,  declining profit margins and increasing
          competition.

The Fund may sell securities when the Adviser believes:

     (BOX)a security becomes widely  recognized by the  professional  investment
          community  as a  result  of  accelerating  revenue  growth,  expanding
          margins and decreased competition;

     (BOX)a security  appreciates in value to the point that it is considered to
          be overvalued;

     (BOX)the Fund's  holdings should be rebalanced to include a more attractive
          stock or stocks; or

     (BOX)an issuer's earnings potential is in jeopardy.

     The Fund may invest in convertible securities.  A convertible security is a
bond,  debenture,  note, preferred stock or other security that may be converted
into or  exchanged  for a  prescribed  amount of  common  stock of the same or a
different  issuer  within a  particular  period of time at a specified  price or
formula. A convertible  security entitles the holder to receive interest paid or
accrued on debt or the dividend  paid on preferred  stock until the  convertible
security  matures or is redeemed,  converted or  exchanged.  Before  conversion,
convertible  securities  have  characteristics  similar to  nonconvertible  debt
securities  in that  they  ordinarily  provide a stable  stream  of income  with
generally  higher  yields  than  those of common  stocks of the same or  similar
issuers. The Fund will invest in convertible  securities without regard to their
credit ratings.

     The Fund may invest up to 20% of the value of its net assets in  securities
of foreign issuers including American  Depository  Receipts  ("ADRs").  ADRs are
receipts  typically  issued  by a U.S.  bank or  trust  company  which  evidence
ownership of  underlying  securities  issued by a foreign  corporation.  For the
purposes of the percentage  limitation  above,  a security of a foreign  company
whose primary  business is in the U.S. will not be considered a foreign security
if it is  denominated  in  U.S.  dollars  and is  principally  traded  on a U.S.
exchange.

     While the Adviser intends to fully invest the Fund's assets at all times in
accordance  with the  above-mentioned  policies,  the Fund reserves the right to
hold up to 100% of its assets,  as a temporary  defensive  measure,  in cash and
eligible U.S. dollar-denominated money market instruments. Eligible money market
instruments  include  bank  obligations,  such as  certificates  of deposit  and
bankers'   acceptances   issued  by  foreign  or  domestic  banks  or  financial
institutions  that have total assets of more than $2.5 billion,  and  commercial
paper rated in the top rating category by S&P, Moody's, D&P or Fitch and unrated
commercial  paper  determined  to be of comparable  quality by the Adviser.  The
Adviser  will  determine  when market  conditions  warrant  temporary  defensive
measures.

RISKS OF INVESTING IN THE FUND

     Investing in the Fund involves the following principal risks:

     SMALL COMPANY RISK.  Investments in common stocks in general are subject to
market,  economic  and  business  risks that will cause their price to fluctuate
over  time.  Therefore,  an  investment  in the  Fund may be more  suitable  for
long-term  investors who can bear the risk of these  fluctuations.  Furthermore,
while securities of small capitalization companies may offer greater opportunity
for capital  appreciation  than larger  companies,  investment in such companies
presents greater risks than investment in larger,  more  established  companies.
Indeed,  historically,  small  capitalization  stocks have been more volatile in
price than larger capitalization stocks. Among the reasons for the greater price
volatility of these  securities are the lower degree of liquidity in the markets
for such stocks, and the potentially greater sensitivity of such small companies
to  changes  in  or  failure  of  management,  and  in  many  other  changes  in
competitive,   business,  industry  and  economic  conditions,  including  risks
associated with limited product lines,  markets,  management depth, or financial
resources. Besides exhibiting greater volatility, micro and small company stocks
may,  to a degree,  fluctuate  independently  of larger  company  stocks.  Small
company  stocks may decline in price as large  company  stocks rise,  or rise in
price as large company stocks decline.  Investors  should  therefore expect that
the price of the Fund's  shares will be more  volatile than the shares of a fund
that invests in larger capitalization stocks. Additionally, while the markets in
securities  of  small  companies  have  grown  rapidly  in  recent  years,  such
securities may trade less frequently and in smaller volume than more widely held
securities. The values of these securities may fluctuate more sharply than those
of other securities, and the Fund may experience some difficulty in establishing
or closing out positions in these securities at prevailing market prices.  There
may be less publicly available information about the issuers of these securities
or less market interest in such securities than in the case of larger companies,
and it may take a longer  period of time for the  prices of such  securities  to
reflect  the full  value of their  issuers'  underlying  earnings  potential  or
assets.

     FOREIGN SECURITY RISK: Since foreign securities are usually  denominated in
foreign  currencies,  the value of the Fund's  portfolio  could be  affected  by
currency exchange rates and exchange control regulations. Other risks include:

     (BOX)seizure, expropriation or nationalization of a company's assets;

     (BOX)less publicly  available  information  and differing  regulations  and
          standards;

     (BOX)the  impact  of  political,   social  or  economic   instability,   or
          diplomatic events;

     (BOX)securities  that are less  liquid  and harder to value than those of a
          U.S. issuer.

     As a result  of these  risks,  the  Fund may be more  volatile  than a fund
investing  solely in U.S.  companies.  These  risks may be  greater  if the Fund
invests in developing countries.

     OPPORTUNITY RISK. As with all mutual funds, the Fund is subject to the risk
of missing out on an opportunity  because the assets necessary to take advantage
of it are tied up in less advantageous investments.

     VALUE  STOCK  RISK.  Although  the Fund will  invest in stocks the  Adviser
believes  to be  undervalued,  there is no  guarantee  that the  prices of these
stocks will not move even lower.

     TEMPORARY  INVESTMENT RISK. The value of money market  instruments tends to
fall when current  interest rates rise.  Money market  instruments are generally
less sensitive to interest rate changes than  longer-term  securities.  When the
Fund's assets are invested in these  instruments,  the Fund may not be achieving
its investment objective.

     CONVERTIBLE  SECURITIES  RISK. When interest rates  increase,  fixed-income
securities  will  decline  in  value.  In  particular,   convertible  securities
frequently have speculative  characteristics  and may be acquired without regard
to minimum quality ratings.  Convertible  securites and obligations rated in the
lowest of the top four  rating  categories  are  subject to  greater  credit and
interest rate risk than higher rated securities.

                                        7
<PAGE>



     YEAR 2000 RISK.  The Fund,  like any  business,  could be  affected  if the
computer  systems  on  which  it  relies  do not  properly  process  information
beginning  on  January 1, 2000.  While  Year 2000  issues  could have a negative
effect on the Fund,  the  Adviser and PFPC are  currently  working to avoid such
problems. The Adviser and PFPC are also working with other systems providers and
vendors to determine their systems' ability to handle Year 2000 problems.  There
is no guarantee, however, that systems will work properly on or after January 1,
2000.  Year 2000 problems may also hurt issuers whose  securities the Fund holds
or securities markets generally.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

PRICING OF FUND SHARES

     Shares of the Fund are priced at their net asset value ("NAV").  The NAV of
the Fund is calculated as follows:

                             Value of Assets Attributable to a Class
         NAV =             - Value of Liabilities Attributable to the Same Class
                           -----------------------------------------------------
                             Number of Outstanding Shares of the Class

     The  Fund's NAV is  calculated  as of the close of  regular  trading  hours
(currently 4:00 p.m.  Eastern time) on each day the New York Stock Exchange (the
"NYSE") is open for business.  The Fund will effect  purchases or redemptions of
Fund shares at the next NAV calculated after receipt of your order or request in
proper form as described below under "Initial Investment by Mail."

     Equity  securities  held by the Fund are valued using the closing  price or
the last sale price on the exchange or in the principal  over-the-counter market
where they are traded. If the last sale price is unavailable, the last available
quote or last bid  price is  normally  used.  Debt  securities  held by the Fund
generally  are valued  based on quoted bid prices.  Short term debt  investments
having  maturities of 60 days or less are  amortized to maturity  based on their
cost. If market quotations are unavailable or if an event occurs after the close
of an exchange  that is expected  to  materially  affect the value of a security
held by the Fund,  securities  and other  assets will be valued at fair value as
determined in good faith by the Adviser  according to procedures  adopted by the
Fund's Board of Directors.

     If the Fund holds foreign equity securities,  the calculation of the Fund's
NAV will not  occur at the same  time as the  determination  of the value of the
foreign equity  securities in the Fund's  portfolio,  since these securities are
traded on foreign exchanges.  Additionally if the foreign equity securities held
by the Fund  trade on days when the Fund does not price its  shares,  the NAV of
the Fund's shares may change when  shareholders  will not be able to purchase or
redeem the  Fund's  shares.  As a result,  the Fund's  pricing  may not  reflect
fluctuations in the value of foreign securities.

PURCHASE OF FUND SHARES

     Shares are  offered on a  continuous  basis and are sold  without any sales
charges.  You may  purchase  Fund Shares  directly  from the Fund at the NAV per
share next  calculated  after your order is  received by the  Transfer  Agent in
proper form.  After an initial  purchase is made, the Transfer Agent will set up
an  account  for  you on  the  Fund's  records,  which  will  show  all of  your
transactions and the balance of the shares you own. You can only purchase shares
on days  the  NYSE is open  and  through  the  means  described  below.  Initial
investments  in the  Fund  must be at  least  $20,000,  and  subsequent  minimum
investments must be at least $2,500. For purposes of meeting the minimum initial
purchase,  clients which are part of  endowments,  foundations  or other related
groups  may be  aggregated.  The Fund's  officers  are  authorized  to waive the
minimum initial and subsequent investment requirements.

     Investors may be charged a fee if they effect transactions through a broker
or agent.  Brokers and other  intermediaries  are authorized to accept orders on
the Fund's behalf and those orders will receive the following day's NAV.


                                       10

     INITIAL  INVESTMENT BY MAIL.  Subject to acceptance by the Fund, an account
may be opened by completing and signing an Account Application and mailing it to
the Fund at the address noted below,  together with a check payable to Schneider
Small Cap Value Fund.  Third party endorsed checks or foreign checks will not be
accepted.

     Schneider Small Cap Value Fund
     c/o PFPC Inc.
     P.O. Box 8945
     Wilmington, DE 19899

     Subject to  acceptance  by the Fund,  payment  for the  purchase  of shares
received  by mail will be  credited  to a  shareholder's  account at the NAV per
share of the Fund next determined after receipt of payment in good order.

     INITIAL  INVESTMENT BY WIRE.  Subject to acceptance by the Fund, shares may
be purchased by wiring  federal funds to PNC Bank (see  instructions  below).  A
completed  Account  Application  must be forwarded to the Transfer  Agent at the
address noted above under  "Initial  Investment by Mail" in advance of the wire.
Notification must be given to the Transfer Agent at (888) 520-3277 prior to 4:00
p.m., Eastern time, on the wire date. (Prior  notification must also be received
from investors with existing accounts.) Funds should be wired to:

     PNC Bank, NA
     Philadelphia, Pennsylvania 19103
     ABA# 0310-0005-3
     Account #86-0172-6452
     F/B/O Schneider Small Cap Value Fund
     Ref. (Shareholder's Name; Account Number)

     Federal  funds  purchases  will be accepted only on a day on which the Fund
and PNC Bank, NA are open for business.

     ADDITIONAL  INVESTMENTS.  Additional  investments  may be made at any  time
($2,500 minimum) by purchasing  shares at NAV by mailing a check to the Transfer
Agent at the address noted above under "Initial  Investment by Mail" (payable to
Schneider  Small Cap Value Fund) or by wiring  monies to the  custodian  bank as
outlined above under "Initial Investment by Wire." Notification must be given to
the Transfer Agent at (888)  520-3277  prior to 4:00 p.m.,  Eastern time, on the
wire date.  Initial and  additional  purchases  made by check cannot be redeemed
until payment of the purchase has been  collected,  which may take up to fifteen
days from the purchase date.

     OTHER  PURCHASE  INFORMATION.  The Fund  reserves  the  right,  in its sole
discretion, to suspend the offering of Shares or to reject purchase orders when,
in the  judgment of  management,  such  suspension  or  rejection is in the best
interest of the Fund.

     Purchases of the Fund's shares will be made in full and  fractional  shares
of the Fund calculated to three decimal places.

REDEMPTION OF FUND SHARES

     You may  redeem  Shares  of the  Fund at the next  NAV  calculated  after a
redemption  request is received by the Transfer  Agent in proper  form.  You can
only  redeem  shares of the Fund on days the NYSE is open and  through the means
described below.

     You may redeem Shares of the Fund by mail,  or, if you are  authorized,  by
telephone.  The value of shares  redeemed  may be more or less than the purchase
price,  depending on the market value of the investment  securities  held by the
Fund. There is no charge for redemptions of shares held for more than 1 year.


                                       11

<PAGE>




     REDEMPTION  BY MAIL.  Your  redemption  requests  should  be  addressed  to
Schneider  Small Cap Value Fund, c/o PFPC Inc.,  P.O. Box 8945,  Wilmington,  DE
19899 and must include:

     (BOX)a letter of instruction, if required, or a stock assignment specifying
          the number of shares or dollar  amount to be  redeemed,  signed by all
          registered  owners of the shares in the exact  names in which they are
          registered;

     (BOX)any required  signature  guarantees,  which are required  when (i) the
          redemption  request  proceeds are to be sent to someone other than the
          registered shareholder(s),  (ii) the redemption request is for $10,000
          or more,  or (iii) a share  transfer  request  is  made.  A  signature
          guarantee  may be  obtained  from a  domestic  bank or trust  company,
          broker,  dealer,  clearing  agency  or  savings  association  who  are
          participants  in a  Medallion  Program  recognized  by the  Securities
          Transfer  Association.  The three  recognized  Medallion  Programs are
          Securities  Transfer Agent Medallion Program (STAMP),  Stock Exchanges
          Medallion Program (SEMP) and New York Stock Exchange,  Inc.  Medallion
          Program  (MSP).  Signature  Guarantees,  which are not a part of these
          programs, will not be accepted. Please note that a notary public stamp
          or seal is not acceptable; and

     (BOX)other  supporting  legal  documents,  if  required,  in  the  case  of
          estates, trusts, guardianships,  custodianships, corporations, pension
          and profit sharing plans and other organizations.

     REDEMPTION  BY  TELEPHONE.  In order to utilize  the  Telephone  Redemption
Option, you must indicate that option on your Account Application.  You may then
initiate a redemption of shares by calling the Transfer  Agent at (888) 520-3277
and  requesting   that  the  redemption   proceeds  be  mailed  to  the  primary
registration address or wired per the authorized instructions.  If the Telephone
Redemption  Option  is  authorized,  the  Transfer  Agent  may act on  telephone
instructions from any person representing himself or herself to be a shareholder
and believed by the Transfer Agent to be genuine.  The Transfer  Agent's records
of such instructions are binding and shareholders,  not the Fund or its Transfer
Agent,  bear  the  risk  of  loss  in the  event  of  unauthorized  instructions
reasonably  believed  by the  Fund or its  Transfer  Agent  to be  genuine.  The
Transfer Agent will employ  reasonable  procedures to confirm that  instructions
communicated  are  genuine  and, if it does not, it may be liable for any losses
due to unauthorized or fraudulent  instructions.  The procedures employed by the
Transfer Agent in connection with  transactions  initiated by telephone  include
tape  recording of telephone  instructions  and requiring  some form of personal
identification prior to acting upon instructions received by telephone.

     TRANSACTION FEE ON CERTAIN REDEMPTIONS.  The Fund requires the payment of a
transaction  fee on  redemptions  of Shares held for less than one year equal to
1.75% of the net asset value of such Shares  redeemed at the time of redemption.
This  additional  transaction  fee is  paid  to the  Fund,  NOT to the  adviser,
distributor or transfer agent. It is NOT a sales charge or a contingent deferred
sales  charge.  The fee does not apply to redeemed  Shares  that were  purchased
through reinvested  dividends or capital gain distributions.  The purpose of the
additional   transaction  fee  is  to  indirectly  allocate   transaction  costs
associated with redemptions to those investors making  redemptions after holding
their shares for a short period,  thus protecting existing  shareholders.  These
costs  include:  (1)  brokerage  costs;  (2) market  impact  costs -- i.e.,  the
decrease  in  market  prices  which  may  result  when  the Fund  sells  certain
securities  in order  to raise  cash to meet  the  redemption  request;  (3) the
realization of capital gains by the other  shareholders in the Fund; and (4) the
effect of the "bid-ask" spread in the over-the-counter  market. The 1.75% amount
represents  the Fund's  estimate of the  brokerage and other  transaction  costs
which may be incurred by the Fund in  disposing  of stocks in which the Fund may
invest.  Without the  additional  transaction  fee, the Fund would  generally be
selling  its shares at a price less than the cost to the Fund of  acquiring  the
portfolio  securities  necessary  to maintain  its  investment  characteristics,
resulting in reduced  investment  performance for all  shareholders in the Fund.
With the additional transaction fee, the transaction costs of selling additional
stocks are not borne by all existing  shareholders,  but the source of funds for
these costs is the transaction fee paid by those investors  making  redemptions.
For  purposes  of  this  redemption  feature,  shares  purchased  first  will be
considered to be shares first redeemed.


                                       12

<PAGE>

     SYSTEMATIC  WITHDRAWAL  PLAN.  If  your  account  has a value  of at  least
$20,000,  you may  establish a Systematic  Withdrawal  Plan and receive  regular
periodic payments.  A request to establish a Systematic  Withdrawal Plan must be
submitted in writing to the Transfer Agent at P.O. Box 8945, Wilmington Delaware
19899. Each withdrawal  redemption will be processed on or about the 25th of the
month and mailed as soon as possible  thereafter.  There are no service  charges
for  maintenance;  the minimum amount that you may withdraw each period is $100.
(This is merely the minimum  amount  allowed  and should not be  mistaken  for a
recommended  amount.) The holder of a Systematic  Withdrawal  Plan will have any
income  dividends  and any capital  gains  distributions  reinvested in full and
fractional shares at net asset value. To provide funds for payment,  Shares will
be  redeemed  in such  amount  as is  necessary  at the  redemption  price.  The
systematic  withdrawal  of Shares may reduce or  possibly  exhaust the Shares in
your  account,  particularly  in the event of a market  decline.  As with  other
redemptions,  a systematic  withdrawal  payment is a sale for federal income tax
purposes.  Payments  made  pursuant to a  Systematic  Withdrawal  Plan cannot be
considered as actual yield or income since part of such payments may be a return
of capital.

     You will ordinarily not be allowed to make  additional  investments of less
than the aggregate  annual  withdrawals  under the  Systematic  Withdrawal  Plan
during the time you have the plan in effect.  You will receive a confirmation of
each  transaction  showing  the  sources of the  payment  and the Share and cash
balance  remaining  in your  account.  The  Systematic  Withdrawal  Plan  may be
terminated  on  written  notice  by the  shareholder  or by the  Fund  and  will
terminate  automatically  if all Shares are  liquidated  or  withdrawn  from the
account or upon the death or incapacity of the  shareholder.  You may change the
amount and schedule of  withdrawal  payments or suspend such  payments by giving
written notice to the Fund's  transfer agent at least ten Business Days prior to
the end of the month preceding a scheduled payment.

     OTHER REDEMPTION  INFORMATION.  Redemption  proceeds for shares of the Fund
recently  purchased  by  check  may not be  distributed  until  payment  for the
purchase has been collected, which may take up to fifteen days from the purchase
date. Shareholders can avoid this delay by utilizing the wire purchase option.

     If the Board of Directors  determines  that it would be  detrimental to the
best interests of the remaining  shareholders of the Fund to make payment wholly
or partly  in cash,  redemption  proceeds  may be paid in whole or in part by an
in-kind  distribution of readily marketable  securities held by the Fund instead
of cash in conformity with applicable rules of the SEC. Investors generally will
incur  brokerage  charges on the sale of  portfolio  securities  so  received in
payment of redemptions.  The Fund has elected,  however,  to be governed by Rule
18f-1 under the Investment Company Act of 1940, so that the Fund is obligated to
redeem its shares  solely in cash up to the lesser of  $250,000 or 1% of its net
asset value during any 90-day period for any one shareholder of the Fund.

     INVOLUNTARY REDEMPTION.  The Fund reserves the right to redeem your account
at any time the net asset value of the account  falls below $5,000 as the result
of a redemption or an exchange request.

     You will be notified in writing that the value of your account is less than
$5,000  and will be allowed 30 days to make  additional  investments  before the
redemption is processed.

DIVIDENDS AND DISTRIBUTIONS

     The Fund will distribute substantially all of the net investment income and
net realized capital gains, if any, of the Fund to the Fund's shareholders.  All
distributions  are  reinvested  in the form of  additional  full and  fractional
Shares unless you elect otherwise.

     The Fund will declare and pay dividends from net investment income annually
and pays them in the  calendar  year in which they are  declared.  Net  realized
capital  gains  (including  net  short-term  capital  gains),  if  any,  will be
distributed at least annually.


                                       13

<PAGE>

TAXES

     FEDERAL TAXES. The Fund  contemplates  declaring as dividends each year all
or substantially all of its taxable income,  including its net capital gain (the
excess of long-term  capital gain over short-term  capital loss).  Distributions
attributable  to the net  capital  gain of the Fund  will be  taxable  to you as
long-term capital gain,  regardless of how long you have held your shares. Other
Fund distributions (other than exempt-interest dividends,  discussed below) will
generally  be taxable as ordinary  income.  You will be subject to income tax on
Fund  distributions  regardless  whether they are paid in cash or  reinvested in
additional  shares.  You  will  be  notified  annually  of  the  tax  status  of
distributions to you.

     You should note that if you purchase shares just before a distribution, the
purchase  price will  reflect the amount of the upcoming  distribution,  but you
will be taxable on the entire amount of the distribution received,  even though,
as an economic matter, the distribution simply constitutes a return of a portion
of your purchase price. This is known as "buying into a dividend."

     You will recognize  taxable gain or loss on a sale,  exchange or redemption
of your shares, based on the difference between your tax basis in the shares and
the  amount you  receive  for them.  (To aid in  computing  your tax basis,  you
generally should retain your account statements for the periods during which you
held shares.)

     Any loss  realized on shares held for six months or less will be treated as
a long-term  capital loss to the extent of any capital gain  dividends that were
received on the shares.

     The one major exception to these tax principles is that  distributions  on,
and  sales,  exchanges  and  redemptions  of,  shares  held in an IRA (or  other
tax-qualified plan) will not be currently taxable.

     The foregoing is only a summary of certain tax considerations under current
law,  which  may be  subject  to  change  in the  future.  Shareholders  who are
nonresident  aliens,  foreign  trusts or  estates,  or foreign  corporations  or
partnerships,  may be subject to  different  United  States  federal  income tax
treatment. You should consult your tax adviser for further information regarding
federal,  state, local and/or foreign tax consequences relevant to your specific
situation.

     The Fund may be required to  withhold  federal  income tax at a rate of 31%
("backup   withholding")   from  dividends  and  redemption   proceeds  paid  to
non-corporate  shareholders.  This tax may be withheld from dividends if (i) you
fail to furnish the Fund with your correct taxpayer  identification number, (ii)
the Internal  Revenue Service ("IRS")  notifies the Fund that you have failed to
report properly  certain  interest and dividend income to the IRS and to respond
to notices to that effect,  or (iii) when required to do so, you fail to certify
that you are not subject to backup withholding.

     STATE AND LOCAL TAXES.  Shareowners  may also be subject to state and local
taxes on  distributions  and  redemptions.  State  income  taxes may not  apply,
however,  to  the  portions  of the  Fund's  distributions,  if  any,  that  are
attributable to interest on federal  securities or interest on securities of the
particular  state or localities  within the state.  Shareowners  should  consult
their tax advisers  regarding the tax status of distributions in their state and
locality.
