The Fund's
objective

The Fund aims to
provide the highest
possible level of
current income while
still maintaining
liquidity and
providing maximum
safety of principal.

The Fund's main
investment strategy

The Fund invests solely in direct debt securities of the U.S. Treasury,
including Treasury bills, bonds and notes. These investments carry different
interest rates, maturities and issue dates.

The Fund does not buy securities issued or guaranteed by agencies of the U.S.
government and it 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 investments which have remaining maturities of 397 days or less.

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, the security may have a guarantee that has
such a rating. If the security is not rated, it must be considered of
comparable quality by the Fund's advisers.

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

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

The Fund may change any of its investment policies (except its investment
objective) without shareholder approval. [Chase Vista planet symbol]

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.

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.

The Year 2000

The Fund, like any business, could be affected if the computer systems on which
it relies fail to properly process information beginning on January 1, 2000. The
Fund's advisers are updating their own systems and encouraging service providers
to do the same, but there's no guarantee these systems will work properly. Year
2000 problems could also hurt issuers whose securities the Funds hold or
securities markets generally. [Chase Vista planet symbol]

An investment in the Fund isn't
a bank deposit and it isn't
insured or guaranteed by the
Federal Deposit Insurance Cor-
poration or any other govern-
ment agency. Although the
100% U.S. Treasury Securities
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 portfo-
lio may not earn as high a cur-
rent 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.

On May 3, 1996, the Hanover 100% Treasury Securities Money Market Fund merged
into the 100% U.S. Treasury Securities Money Market Fund. The Fund's
performance figures for the period before that date are for the Hanover fund.

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. [Chase Vista planet

The Fund's
objective

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

The Fund's main
investment strategy

The Fund invests at least 65% of its assets in direct debt securities of the
U.S. Treasury, including Treasury bills, bonds and notes, and repurchase agree-
ments collateralized by these invest- ments. These debt securities carry
different interest rates, maturities and issue dates.

The Fund also seeks to enhance its performance by investing in repurchase
agreements, using debt securities guaranteed by the U.S. Treasury as
collateral.

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.

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.

CHASE VISTA CASH MANAGEMENT FUND

The Fund's
objective

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

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 90 days or less and
the Fund will buy only those instruments which have remaining maturities of 397
days or less.

CHASE VISTA CASH MANAGEMENT FUND

The Fund seeks to develop an appropriate portfolio by considering the

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.

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.

The Year 2000

An investment in the Fund isn't a
bank deposit and it isn't insured or
guaranteed by the Federal Deposit
Insurance Corporation or any other
government agency. Although the
Cash Management 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

CHASE VISTA PRIME MONEY MARKET FUND

The Fund's
objective

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

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 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 investment policies (except its investment
objective) without shareholder approval. [Chase Vista planet symbol]

CHASE VISTA PRIME MONEY MARKET FUND

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.

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

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.

The Year 2000

An investment in the Fund isn't a
bank deposit and it isn't insured or
guaranteed by the Federal Deposit
Insurance Corporation or any other
government agency. Although the
Prime Money Market Fund seeks to
preserve the value of your invest-
ment at $1.00 per share, it is pos-
sible 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.

CHASE VISTA TAX FREE MONEY MARKET FUND

The Fund's
objective

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

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
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, the security may have a guarantee that has
such a rating. 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 and

27

CHASE VISTA TAX FREE MONEY MARKET FUND

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. [Chase Vista planet symbol]

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.

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.

Some municipal obligations, including municipal lease obligations, carry
additional risk. Under some circumstances, municipal obligations do not pay
interest unless the municipality's legislature authorizes money for that
purpose. They may be difficult to trade and interest payments may be tied only
to a specific stream of revenue.

An investment in the Fund isn't a
bank deposit and it isn't insured
or guaranteed by the Federal
Deposit Insurance Corporation or
any other government agency.
Although the 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.

28
<PAGE>

Since some municipal obligations may be secured or guaranteed by banks and
other institutions, the risk to the Fund could increase if the municipalities
have problems with the banking or financial sector.

Interest on certain municipal obligations is subject to the federal alternate
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. 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.

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.

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.

The Year 2000

The Fund, like any business, could be affected if the computer systems on which
it relies fail to properly process information beginning on January 1, 2000.
The Fund's advisers are updating their own systems and encouraging service
providers to do the same, but there's no guarantee these systems will work
properly. Year 2000 problems could also hurt issuers whose securities the Funds
hold or securities markets generally.[Chase Vista planet symbol]

HOW YOUR ACCOUNT WORKS

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.

The NAV of each class of shares is generally calculated by 6:00 p.m. Eastern
time, each day the Funds are accepting purchase orders. You'll pay the next NAV
calculated after the Chase Vista Funds Service Center receives your 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 you send us an
order in proper form by the Fund's cut-off time, we'll process

33
<PAGE>

HOW YOUR ACCOUNT WORKS

your order at that day's price and you'll be entitled to all dividends declared
on that day. If we receive your order after the cut-off time, we'll generally
process it at the next day's price, but we may process it that day if we
receive it before 4:00 p.m. (Eastern time). If you pay by check before the
cut-off time, we'll generally process your order the next day the Fund is open
for business. Normally, the cut-off (in Eastern time) is:

A later cut-off time may be permitted for investors buying their shares
[through Chase or a bank/affiliate of Chase] so long as such later cut-off time
is before the Fund's NAV is calculated. If you buy through an agent and not
directly from the Chase Vista Funds Service Center, the agent could set earlier
cut-off times. Each Fund can set an earlier cut-off time if the Public
Securities Association recommends that the U.S. Government securities market
close trading early.

You must provide a Taxpayer Identification Number when you open an account.

The Funds have the right to reject any purchase order.[Chase Vista planet

QUALIFIED INVESTORS
Premier shares are available only to qualified investors. These are defined as
institutions, trusts, partnerships, corporations and certain retirement plans
and fiduciary accounts opened by a bank, trust company or thrift institution
which has investment authority over such accounts.[Chase Vista planet symbol]

MINIMUM INVESTMENTS
First time investors must buy a minimum $100,000 worth of Premier Shares in a
Fund to open an account. There are no minimum levels for subsequent purchases,
but you must always have at least $100,000 in your account.

Make your check out to Chase Vista Funds in U.S. dollars. We won't accept
credit cards, cash, or checks from a third party. You cannot sell your shares
until your check has cleared, which could take 15 calendar days. If you buy
through an Automated Clearing House, you can't sell your shares until the
payment clears. That could take more than seven business days. Your purchase
will be canceled if your check doesn't clear and you'll be responsible for any
expenses and losses to the Funds. Orders by wire will be canceled if the Chase
Vista Funds Service Center doesn't receive payment by 4:00 Eastern time on the
day you buy.[Chase Vista planet symbol]

OPENING YOUR ACCOUNT AND
BUYING SHARES

Through your investment representative

Tell your representative which Funds you want to buy and he or she will contact
us. To purchase or redeem shares your representative must call the Chase Vista
Funds Service Center. Funds for purchase should be wired to:

Chase Manhattan Bank
ABA# 021-000-021
Deposit Account # 323-125832
Reference: Fund number and account number.

Your representative may charge you a fee and may offer additional services,
such as special purchase and redemption programs, "sweep" programs, cash
advances and redemption checks. Your representative may set different minimum
investments and earlier cut-off times.

You may add to your account by wiring the purchase amount to CMB with the
instructions above. Please call your representative prior to wiring additional
funds to your account.[Chase Vista planet symbol]

Selling Fund shares

You can sell your shares on any day the Chase Vista Funds Service Center is
open for trading, either directly to the Fund or through your investment
representative. You'll receive the next NAV calculated after the Chase Vista
Funds Service Center accepts your order.

Under normal circumstances, if your request is received before the Fund's
cut-off time, the Fund will send you the proceeds the next business day. We
won't accept an order to sell shares if the Fund hasn't collected your payment
for the shares. The Fund may stop accepting orders to sell and may postpone
payments for more than seven days, as federal securities laws permit.

You'll need to have your signature guaranteed if you want your payment sent to
an address other than the one we have in our records. We may also need
additional documents or a letter from a surviving joint owner before selling
the shares.[Chase Vista planet symbol]

SELLING SHARES

Through your investment representative

Tell your representative which Funds you want to sell. He or she will send the
necessary documents to the Fund. Your representative might charge you for this
service. [Chase Vista planet symbol]

HOW YOUR ACCOUNT WORKS

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. The U.S.
Government Money Market Fund has adopted a Rule 12b-1 distribution plan under
which it pays up to 0.10% of its Premier Class assets in distributor fees.

This payment covers 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.[Chase Vista planet symbol]

Other information concerning the funds

We may close your account if the balance falls below $100,000 because you've
sold shares. We may also close the account if you fail to meet investment
minimums in 12 months. We'll give you 60 days notice before closing your
account.

Unless you indicate otherwise on your account application, we are authorized to
act on redemption and transfer instructions received by phone. If someone
trades on your account by phone, we'll ask that person to confirm your account
registration and address to make sure they match those you provided us. If they
give us the correct information, we are generally authorized to follow that
person's instructions. We'll take all reasonable precautions to confirm that
the instructions are genuine. Investors agree that they will not hold the Fund
liable for any loss or expenses from any sales request, if the Fund takes
reasonable precautions. The Fund will be liable for any losses to you from an
unauthorized sale or fraud against you if we do not follow reasonable
procedures.

You may not always reach the Chase Vista Funds Service Center by telephone.
This may be true at times of unusual market changes and shareholder activity.
You can mail us your instructions or contact your investment representative or
agent. We may modify or cancel the sale of shares by phone without notice.

The Trust has 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 0.25% of the
average daily net assets of the Premier Shares of each Fund held by investors
serviced by the shareholder servicing agent.

Chase and/or VFD may, at their own expense, make additional payments to certain
selected dealers or other shareholder servicing agents for performing
administrative ser-

36
<PAGE>

vices 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.

Each Fund may issue multiple classes of shares. This prospectus relates only to
Premier 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 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 sharing is prohibited by contract. This
information can be used for a variety of purposes, including offering
investment and insurance products to shareholders.[Chase Vista planet symbol]

Distributions and taxes

The Funds can earn income and they can realize capital gain. The Funds deduct
any expenses then pay out these earnings to shareholders as 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 you tell 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 Funds 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 send you a notice showing the
amount of distributions you received 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 adviser to see how investing in the Funds will
affect your own tax situation.[Chase Vista planet symbol]

SHAREHOLDER SERVICES

EXCHANGE PRIVILEGES

You can exchange your Premier shares for shares in certain other Chase Vista

exchange. You'll need to meet any minimum investment requirements and may have
to pay a sales charge. Call Warner Asset Management, Inc. at 1-888-742-2111 for
details.

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.
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.
