The Fund's objective

The Fund aims to provide current income while still preserving capital and
maintaining liquidity.

[End sidebar]


The Fund's main investment strategy

The Fund invests primarily in:

o    direct debt securities of the U.S. Treasury, including Treasury bills,
     bonds and notes, and

o    debt securities that certain U.S. government agencies or authorities have
     either issued or guaranteed as to principal and interest.

The Fund does not enter into repurchase agreements. The dollar weighted average
maturity of the Fund will be 90 days or less and the Fund will buy only those
instruments which have remaining maturities of 397 days or less.

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

The Fund may invest significantly in securities with floating or variable rates
of interest. Their yields will vary as interest rates change.

The Fund invests only in securities issued and payable in U.S. dollars. Each
investment must have the highest possible short-term rating from at least two
national rating organizations, or one such rating if only one organization rates
that security. Alternatively, some securities may have additional third party
guarantees, in order to meet the rating requirements mentioned above. If the
security is not rated, it must be considered of comparable quality by the Fund's
advisers.

CHASE VISTA FEDERAL MONEY MARKET FUND


The Fund seeks to develop an appropriate portfolio by considering the
differences in yields among securities of different maturities, market sectors
and issuers.

The Fund may change any of its investment policies (except its investment
objective) without shareholder approval.[logo]


The Fund's main investment risks

The Fund attempts to keep its net asset value constant, but there's no guarantee
it will be able to do so.

The value of money market investments tends to fall when prevailing interest
rates rise, although they're generally less sensitive to interest rate changes
than longer-term securities.


Although the Fund seeks to be fully invested, it may at times hold some of its
assets in cash. This would hurt the Fund's performance.[logo]



[Begin sidebar]

Investments in the Fund are not bank deposits or obligations of, or guaranteed
or endorsed by, The Chase Manhattan Bank or any of its affiliates and are not
insured by the FDIC, the Federal Reserve Board or any other government agency.
Although the Federal Money Market Fund seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in the
Fund.

Securities in the Fund's portfolio may not earn as high a current income as
longer term or lower-quality securities.

The Fund's past performance

This section shows the Fund's performance record. The bar chart shows how the
performance of the Fund has varied from year to year. This provides some
indication of the risks of investing in the Fund.


Because Reserve shares were not launched until July 31, 2000, the performance
shown is based on performance for Vista Class shares of the Fund. The actual
returns of Reserve Class shares would have been lower than shown because Reserve
Class shares have higher expenses than Vista Class shares.


The calculations assume that all dividends and distributions are reinvested in
the Fund. Some of the companies that provide services to the Fund have agreed
not to collect some expenses and to reimburse others. Without these agreements,
the performance figures would be lower than those shown.[logo]

The Fund's objective

The Fund aims to provide the highest possible level of current income while
still maintaining liquidity and preserving capital.

[End sidebar]


The Fund's main investment strategy

The Fund invests in high quality, short-term money market instruments which are
issued and payable in U.S. dollars. The Fund principally invests in:

o    high quality commercial paper and other short-term debt securities,
     including floating and variable rate demand notes of U.S. and foreign
     corporations

o    debt securities issued or guaranteed by qualified banks. These are:

     o    U.S. banks with more than $1 billion in total assets, and foreign
          branches of these banks

     o    foreign banks with the equivalent of more than $10 billion in total
          assets and which have branches or agencies in the U.S.

     o    other U.S. or foreign commercial banks which the Fund's advisers judge
          to have comparable credit standing

o    securities issued or guaranteed by the U.S. Government, its agencies or
     authorities

o    asset-backed securities

o    repurchase agreements

The dollar weighted average maturity of the Fund will be 60 days or less and the
Fund will buy only those instruments which have remaining maturities of 397 days
or less.

CHASE VISTA PRIME MONEY MARKET FUND


The Fund may invest any portion of its assets in debt securities issued or

The Fund invests only in securities issued and payable in U.S. dollars. Each
investment must have the highest possible short-term rating from at least two

The Fund's main investment risks


The Fund attempts to keep its net asset value constant, but there's no guarantee
it will be able to do so.

The value of money market investments tends to fall when prevailing interest
rates rise, although they're generally less sensitive to interest rate changes
than longer-term securities.

Repurchase agreements involve some risk to the Fund if the other party does not
live up to its obligations under the agreement.

The Fund's ability to concentrate 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.

Investments in foreign banks and other foreign issuers may be riskier than
investments in the United States. That could be, in part, because of difficulty
converting investments into cash, political and economic instability,
the imposition of government controls, or
regulations that don't match U.S. standards.


Although the Fund seeks to be fully invested, it may at times hold some of its
assets in cash. This would hurt the Fund's performance.[logo]

The Fund's objective

The Fund aims to provide the highest possible level of current income which is
excluded from gross income (for federal income tax purposes), while still
preserving capital and maintaining liquidity.

[End sidebar]


The Fund's main investment strategy

Under normal market conditions, the Fund will try to invest 100% of its assets
in municipal obligations, the interest on which is excluded from gross income
(for federal income tax purposes) and which is not subject to the alternative
minimum tax on individuals.

As a fundamental policy, the Fund will invest at least 80% of its assets in
municipal obligations. The remaining 20% of total assets may be invested in
securities which are subject to federal income tax or the federal alternative
minimum tax for individuals. To temporarily defend its assets, the Fund may
exceed this limit.

The Fund may also invest in municipal lease obligations. These provide
participation in municipal lease agreements and installment purchase contracts.

The Fund invests only in securities issued and payable in U.S. dollars.

Each investment must have the highest possible short-term rating from at least
two national rating organizations, or one such rating if only one organization
rates that security. Alternatively, some securities may have additional third
party guarantees, in order to meet the rating requirements mentioned above. If
the security is not rated, it must be considered of comparable quality by the
Fund's advisers.


                                       10
<PAGE>


The dollar-weighted average maturity of the Fund will be 90 days or less and the
Fund will buy only those investments which have remaining maturities of 397 days
or less.

The Fund seeks to develop an appropriate portfolio by considering the
differences in yields among securities of different maturities, market sectors
and issuers.

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

The Fund may change any of its non-fundamental investment policies (except its
investment objective) without shareholder approval.[logo]


The Fund's main investment risks

The Fund attempts to keep its net asset value constant, but there's no
guarantee it will be able to do so.

The value of money market investments tends to fall when prevailing interest
rates rise, although they're generally less sensitive to interest rate changes
than longer-term securities.

Changes in a municipality's financial health may make it difficult for the
municipality to make interest and principal payments when due. A number of
municipalities have had significant financial problems recently. This could
decrease the Fund's income or hurt its ability to preserve capital and
liquidity.


Under some circumstances, municipal obligations might not pay interest unless
the state or municipal legislature authorizes money for that purpose. Some
securities, including

CHASE VISTA TAX FREE MONEY MARKET FUND



municipal lease obligations, carry additional risk. For example, they may be
difficult to trade or interest payments may be tied only to a specific stream of
revenue.


Since some municipal obligations may be secured or guaranteed by banks and other
institutions, the risk to the Fund could increase if the banking or financial
sector suffers an economic downturn.

Interest on certain municipal obligations is subject to the federal alternative
minimum tax. Normally, up to 20% of the Fund's total assets may be invested in
securities that are subject to this tax. Consult your tax professional for more
information.


The Fund may invest in municipal obligations backed by foreign institutions.
This could carry more risk than securities backed by U.S. institutions, in part,
because of political and economic instability, the imposition of government
controls, or regulations that don't match U.S. standards.

The Fund is not diversified. It may invest a greater percentage of its assets in
a particular issuer or group of issuers than a diversified fund would. That
makes it more susceptible to economic problems among the institutions issuing
the securities. In addition, more than 25% of the Fund's assets may be invested
in securities which rely on similar projects for their income stream. As a
result, the Fund could be more susceptible to developments which affect those
projects.

Although the Fund seeks to be fully invested, it may at times hold some of its
assets in cash. This would hurt the Fund's performance.[logo]

The Fund's objective

The Fund aims to provide the highest possible level of current income which is
excluded from gross income and exempt from New York State and New York City
personal income taxes, while still preserving capital and maintaining liquidity.

[End sidebar]


The Fund's main investment strategy

The Fund will generally invest at least 65% of its assets in New York municipal
obligations, the interest of which is exempt from gross income and exempt from
New York State and New York City personal income taxes. The exact percentage
will vary from time to time. New York municipal obligations are municipal
obligations issued by New York State, its political subdivisions, Puerto Rico,
other U.S. territories and their political subdivisions.

When suitable New York municipal obligations are unavailable, the Fund may buy
municipal obligations issued by other states. These are generally subject to New
York State and New York City personal income taxes.

As a fundamental policy, under normal market conditions, the Fund will invest at
least 80% of its assets in municipal obligations, the interest on which is
excluded from gross income and which is not subject to the federal alternate
minimum tax on individuals. The remaining 20% of its total assets may be
invested in securities paying interest which is subject to federal income tax or
to the alternate minimum tax on individuals. To temporarily defend its assets,
the Fund may exceed this limit.

The Fund may also invest in municipal lease obligations. These provide
participation in municipal lease agreements and installment purchase contracts.


                                       15

CHASE VISTA NEW YORK TAX FREE MONEY MARKET FUND


The Fund invests only in securities issued and payable in U.S. dollars. Each
investment must have the highest or second-highest possible short-term rating
from at least two national rating organizations, or one such rating if only one
organization rates that security. Alternatively, some securities may have
additional third party guarantees, in order to meet the rating requirements
mentioned above. If the security is not rated, it must be considered of
comparable quality by the Fund's advisers. The dollar-weighted average maturity
of the Fund will be 90 days or less.

The Fund seeks to develop an appropriate portfolio by considering the
differences in yields among securities of different maturities, market sectors
and issuers.

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

The Fund may change any of its non-fundamental investment policies (except its
investment objective) without shareholder approval.[logo]


[Begin sidebar]

Investments in the Fund are not bank deposits or obligations of, or guaranteed
or endorsed by, The Chase Manhattan Bank or any of its affiliates and are not
insured by the FDIC, the Federal Reserve Board or any other government agency.
Although the New York Tax Free Money Market Fund seeks to preserve the value of
your investment at $1.00 per share, it is possible to lose money by investing in
the Fund.

Securities in the Fund's portfolio may not earn as high a current income as
longer term or lower-quality securities.

[End sidebar]


                                       16

The main investment risks

The Fund attempts to keep its net asset value constant, but there's no guarantee
it will be able to do so.

The value of money market investments tends to fall when prevailing interest
rates rise, although they're generally less sensitive to interest rate changes
than longer-term securities.

The Fund will be particularly susceptible to difficulties affecting New York
State and its municipalities. Changes in a municipality's financial health may
make it difficult for the municipality to make interest and principal payments
when due. A number of municipal issuers, including the State of New York and New
York City, have a recent history of financial problems. Such problems could
decrease the Fund's income or hurt its ability to preserve capital and
liquidity.


Under some circumstances, municipal obligations might not pay interest unless
the state or municipal legislature authorizes money for that purpose. Some
securities, including municipal lease obligations, carry additional risk. For
example, they may be difficult to trade or interest payments may be tied only to
a specific stream of revenue.

Since some municipal obligations may be secured or guaranteed by banks and other
institutions, the risk to the Fund could increase if the banking or financial
sector suffers an economic downturn.


Interest on certain municipal obligations is subject to the federal alternative
minimum tax. Normally, up to 20% of the Fund's total assets may be invested in
securities that are subject to this tax. Consult your tax professional for more
information.


The Fund may invest in municipal obligations backed by foreign institutions.
This could carry more risk than securities backed by U.S. institutions, because
of political and economic instability, the imposition of government controls, or
regulations that don't match U.S. standards.

The Fund is not diversified. It may invest a greater percentage of its assets in
a particular issuer or group of issuers than a diversified fund would. That
makes it more susceptible to economic problems among the institutions issuing
the securities. In addition, more than 25% of the Fund's assets may be invested
in securities which rely on similar projects for their income stream. As a
result, the Fund could be more susceptible to developments which affect those
projects.

Although the Fund seeks to be fully invested, it may at times hold some of its
assets in cash. This would hurt the Fund's performance.[logo]

The Fund's past performance

This section shows the Fund's performance record. The bar chart shows how the
performance of the Fund has varied from year to year. This provides some
indication of the risks of investing in the Fund.


Because Reserve shares were not launched until July 31, 2000, the performance
shown is based on performance for Vista Class shares of the Fund. The actual
returns of Reserve Class shares would have been lower than shown because Reserve
Class shares have higher expenses than Vista Class shares.

The calculations assume that all dividends and distributions are reinvested in
the Fund. Some of the companies that provide services to the Fund have agreed
not to collect some expenses and to reimburse others. Without these agreements,
the performance figures would be lower than those shown.[logo]

HOW YOUR ACCOUNT WORKS
--------------------------------------------------------------------------------



Reserve shares are available for purchase only through participating sweep
programs offered through Chase or other financial institutions. All purchases
and redemptions on an investor's behalf will be placed through the customer's
sweep agent or representative.



Buying Fund shares

You don't pay any sales charge (sometimes called a load) when you buy shares in
these funds.

The price you pay for your shares is the net asset value per share (NAV). NAV is
the value of everything the Fund owns, minus everything it owes, divided by the
number of shares held by investors. All of these Funds seek to maintain a stable
NAV of $1.00. Each Fund uses the amortized cost to value its portfolio of
securities. This method provides more stability in valuations. However, it may
also result in periods during which the stated value of a security is different
than the price the Fund would receive if it sold the investment.


                                       21
<PAGE>


CHASE VISTA TAX FREE MONEY MARKET FUND


The NAV of each class of shares is generally calculated as of 4:00 p.m. Eastern
time, each day the Funds are accepting purchase orders. When certain automated
share purchase programs are introduced, we'll also calculate the NAV at 6:00
p.m. for Funds available through those programs. You'll pay the next NAV
calculated after the Chase Vista Funds Service Center receives your sweep
agent's or representative's order in proper form. An order is in proper form
only after funds are converted into federal funds.

The center accepts purchase orders on any business day that the Federal Reserve
Bank of New York and the New York Stock Exchange are open. If we receive your
sweep agent's or representative's order in proper form by the Fund's cut-off
time, we'll process the order at that day's price and you'll be entitled to all
dividends declared on that day. If we receive the order after the cut-off time,
we'll generally process it at the next day's price, but for Tax Free, New York
Tax Free and Federal Money Market Fund orders we may process it the same day if
we receive it after cut off but before 4:00 p.m. (Eastern time). Normally, the
cut-off (in Eastern time) is:

The Funds may close earlier a few days each year if the Public Securities
Association recommends that the U.S. Government securities market close trading
early. You should consult your cash sweep agreement for more information on when
your sweep agent or representative transmits purchase orders to the Funds.

The Funds have the right to reject any purchase order.

OPENING YOUR ACCOUNT AND BUYING SHARES


Accounts are opened and purchases are made through your sweep agent or
representative. Consult your sweep agent or representative to learn how to
designate a Fund for investment. Your sweep agent or representative may charge
you a fee and may offer services in addition to sweep services, such as special
purchase and redemption programs, cash advances and redemption checks. Although
the Funds have no minimum investment required, your sweep agent or
representative may set a minimum investment requirement, as well as earlier
cut-off times.[logo]



Selling Fund shares

Orders to sell Fund shares are accepted on any day the Chase Vista Funds Service
Center is open for trading. You'll receive the next NAV calculated after the
Chase Vista Funds Service Center accepts your sweep agent's or representative's
order. Your sweep agent or representative is responsible for sending us the
necessary instructions and may charge you for this service.


                                       22
<PAGE>


Under normal circumstances, if a request is received before the Fund's cut-off
time, the Fund will send your sweep agent or representative the proceeds the
same business day. The Fund may stop accepting orders to sell and may postpone
payments for more than seven days, as federal securities laws permit.

DISTRIBUTION ARRANGEMENTS

Vista Fund Distributors Inc. (VFD) is the distributor for the Funds. It is a
subsidiary of The BISYS Group, Inc. and is not affiliated with Chase. All of the
Funds have adopted a Rule 12b-1 distribution and service plan under which they
pay up to 0.30% of their Reserve Class assets in distribution fees.


These payments cover such things as payments for services provided by
broker-dealers and expenses connected to sale of shares. Payments are not tied
to the amount of actual expenses incurred. Because 12b-1 expenses are paid out
of a fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than other types of sales charges.


Under the plan, the Trust has also entered into agreements with certain
shareholder servicing agents (including Chase) under which the shareholder
servicing agents have agreed to provide certain support services to their
customers. For performing these services, each shareholder servicing agent
receives an annual fee of up to 0.35% of the average daily net assets of the
Reserve Shares of each Fund held by investors serviced by the shareholder
servicing agent. These fees are payable for the administration and servicing of
shareholder accounts and are not costs which are primarily intended to result in
the sale of Fund shares. The Board of Trustees has determined that the amount
payable for "service fees" (as defined by the NASD) does not exceed 0.25% of the
average annual net assets attributable to the Reserve Shares of each Fund.

Chase and/or VFD may, at their own expense, make additional payments to certain
selected dealers or other shareholder servicing agents for performing
administrative services for their customers. The amount may be up to an
additional 0.10% annually of the average net assets of the fund attributable to
shares of the Fund held by customers of those shareholder servicing agents.

OTHER INFORMATION CONCERNING THE FUNDS

Each Fund may issue multiple classes of shares. This prospectus relates only to
the Reserve Class shares of the Funds. Each class may have different
requirements for who may invest, and may have different sales charges and
expense levels. A person who gets compensated for selling Fund shares may
receive a different amount for each class.

Chase and its affiliates and the Funds and their affiliates, agents and
subagents may share information about shareholders and their accounts with each
other and with others unless this

CHASE VISTA TAX FREE MONEY MARKET FUND


sharing is prohibited by contract. This information can be used for a variety of
purposes, including offering investment and insurance products to
shareholders.[logo]


Distributions and taxes

The Funds can earn income and they can realize capital gain. The Funds will
deduct from these earnings any expenses and then pay to shareholders the
distributions.

The Funds declare dividends daily, so your shares can start earning dividends on
the day you buy them. We distribute the dividends monthly in the form of
additional shares, unless your sweep agent or representative tells us that you
want payment in cash or deposited in a pre-assigned bank account. The taxation
of dividends won't be affected by the form in which you receive them. We
distribute any short-term capital gain at least annually. The Funds do not
expect to realize long-term capital gain.


Dividends are usually taxable as ordinary income at the federal, state and local
levels. Dividends of tax-exempt interest income by the Tax Free Money Market
Fund and the New York Tax Free Money Market Fund are not subject to federal
income taxes but will generally be subject to state and local taxes. The state
or municipality where you live may not charge you state and local taxes on
tax-exempt interest earned on certain bonds. Dividends earned on bonds issued by
the U.S. government and its agencies may also be exempt from some types of state
and local taxes.


If you receive distributions of net capital gain, the tax rate will be based on
how long the Fund held a particular asset, not on how long you have owned your
shares.

Early in each calendar year, the Funds will provide a notice showing the amount
of distributions paid in the preceding year and the tax status of those
distributions.

The above is only a general summary of tax implications of investing in these
Funds. Please consult your tax advisor to see how investing in the Funds will
affect your own tax situation.[logo]

What the terms mean

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

DEMAND NOTES: A debt security with no set maturity date. The investor can
generally demand payment of the principal at any time.

DISTRIBUTION FEE: Covers the cost of the distribution system used to sell shares
to the public.

DOLLAR WEIGHTED AVERAGE MATURITY: The average maturity of the Fund is 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 debt security in the Fund, the
more weight it gets in calculating this average.

FLOATING RATE SECURITIES: Securities whose interest rates adjust automatically
whenever a particular interest rate changes.

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

MANAGEMENT FEE: A fee paid to the investment adviser to manage the Fund and make
decisions about buying and selling the Fund's investments.

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 OBLIGATIONS: Debt securities issued by or on behalf of states,
territories and possessions or by their agencies or other groups with authority
to act for them. For securities to qualify as municipal obligations, the
municipality's lawyers must give an opinion that the interest on them is not
considered gross income for federal income tax purposes.

OTHER EXPENSES: Miscellaneous items, including transfer agency, administration,
shareholder servicing, custody and registration fees.

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

SHAREHOLDER SERVICE FEE: A fee to cover the cost of paying shareholder servicing
agents to provide certain support services for your account.

VARIABLE RATE SECURITIES: Securities whose interest rates are periodically
adjusted.[logo]
