MORE INFORMATION ON EACH FUND CAN BE FOUND IN THE FUND'S CURRENT
ANNUAL/SEMIANNUAL REPORT. SEE BACK COVER.

Introduction

Each fund is a money market mutual fund with a separate investment portfolio.
The operations and results of a fund are unrelated to those of each other fund.
This combined prospectus has been prepared for your convenience so that you can
consider nine investment choices in one document.

As a money market fund, each fund is subject to maturity, quality and
diversification requirements designed to help it maintain a stable share price.

Generally, each fund is required to invest at least 95% of its assets in the
securities of issuers with the highest credit rating or the unrated equivalent
as determined by Dreyfus, with the remainder invested in securities with the
second-highest credit rating. Dreyfus Cash Management and Dreyfus Cash
Management Plus purchase securities with the highest credit rating only, or the
unrated equivalent. Dreyfus Government Prime Cash Management and Dreyfus
Treasury Prime Cash Management invest only in U.S. government securities.

An investment in a fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although each fund seeks
to preserve the value of your investment at $1.00 per share, it is possible to
lose money by investing in a fund.

Concepts to understand

MONEY MARKET FUND: a specific type of fund that seeks to maintain a $1.00 price
per share. Money market funds are subject to strict federal requirements and
must:

*  maintain an average dollar-weighted portfolio maturity of 90 days or
less

*  buy individual securities that have remaining maturities of 13 months or
less

*  invest only in high quality, dollar-denominated obligations

CREDIT RATING: a measure of the issuer's expected ability to make all required
interest and principal payments in a timely manner. An issuer with the highest
credit rating has a very strong degree of certainty (or safety) with respect to
making all payments. An issuer with the second-highest credit rating has a
strong capacity to make all payments, but the degree of safety is somewhat less

Dreyfus Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

*   securities issued or guaranteed by the U.S. government or its agencies
   or instrumentalities

*   certificates of deposit, time deposits, bankers' acceptances, and other
   short-term securities issued by domestic banks or London branches of domestic
   banks

*   repurchase agreements, including tri-party repurchase agreements

*   high grade commercial paper, and other short-term corporate
   obligations, including those with floating rates of interest

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

*   the risks generally associated with concentrating investments in the
banking industry, such as interest rate risk, credit risk and regulatory
developments relating to the banking industry

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Institutional share class performance from
year to year. The second table averages the fund's performance over time. Both
tables assume reinvestment of dividends. Of course, past performance is no
guarantee of future results.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.


EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

</TABLE>


This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

OTHER EXPENSES: as to the fund's Institutional shares, under an agreement with
Dreyfus, the fund only pays the management fee. Dreyfus pays all other fund
expenses directly. Dreyfus may terminate this agreement upon at least 90 days'
prior notice to investors, but has committed not to do so at least through May
31, 2000.

   or their subsidiaries or branches

*   repurchase agreements, including tri-party repurchase agreements

*   asset-backed securities

*   domestic and dollar-denominated foreign commercial paper, and other
   short-term corporate obligations, including those with floating or variable
   rates of interest

*   dollar-denominated obligations issued or guaranteed by one or more
   foreign governments or any of their political subdivisions or agencies

Normally, the fund invests at least 25% of its net assets in bank obligations.

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are

developments relating to the banking industry

*   the risks generally associated with dollar-denominated foreign
investments, such as economic and political developments, seizure or
nationalization of deposits, imposition of taxes or other restrictions on the
payment of principal and interest

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund invests in securities issued or guaranteed as to
principal and interest by the U.S. government or its agencies or
instrumentalities, and repurchase agreements (including tri-party repurchase
agreements) in respect of these securities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
the securities are subject to a greater risk in a change in their value because
they may have a maturity of more than one year.


Certain U.S. government agency securities are backed by the right of the issuer
to borrow from the U.S. Treasury, or are supported only by the credit of the
issuer or instrumentality. While the U.S. government provides financial support
to U.S. government-sponsored agencies or instrumentalities, no assurance can be
given that it will always do so.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

OTHER EXPENSES: as to the fund's Institutional shares, under an agreement with
Dreyfus, the fund only pays the management fee. Dreyfus pays all other fund
expenses directly. Dreyfus may terminate this agreement upon at least 90 days'
prior notice to investors, but has committed not to do so at least through May
31, 2000.

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund only invests in securities issued or guaranteed as
to principal and interest by the U.S. government or its agencies or
instrumentalities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

Certain U.S. government agency securities are backed by the right of the issuer
to borrow from the U.S. Treasury, or are supported only by the credit of the
issuer or instrumentality. While the U.S. government provides financial support
to U.S. government-sponsored agencies or instrumentalities, no assurance can be
given that it will always do so.

Dreyfus Treasury Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund only invests in securities issued or guaranteed as
to principal and interest by the U.S. government, and repurchase agreements
(including tri-party repurchase agreements) in respect of these securities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

Dreyfus Tax Exempt Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal personal
income tax as is consistent with the preservation of capital and the maintenance
of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal personal
income tax. When the portfolio manager believes that acceptable municipal
obligations are unavailable for investment, the fund may invest temporarily in
high quality, taxable money market instruments.

Municipal obligations are typically divided into two types:

*   GENERAL OBLIGATION BONDS, which are secured by the full faith and
   credit of the issuer and its taxing power

*   REVENUE BONDS, which are payable from the revenues derived from a
   specific revenue source, such as charges for water and sewer service or
   highway tolls

While the fund is permitted to invest up to 20% of its assets in municipal
obligations that pay interest that may be subject to the federal alternative
minimum tax, the fund currently is managed so that income paid by the fund will
not be subject to the federal alternative minimum tax.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

OTHER EXPENSES: as to the fund's Institutional shares, under an agreement with
Dreyfus, the fund only pays the management fee. Dreyfus pays all other fund
expenses directly. Dreyfus may terminate this agreement upon at least 90 days'
prior notice to investors, but has committed not to do so at least through May
31, 2000.


Dreyfus Tax Exempt Cash Management

<PAGE 15>

Dreyfus Municipal Cash Management Plus

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal personal
income tax as is consistent with the preservation of capital and the maintenance
of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal personal
income tax. When the portfolio manager believes that acceptable municipal
obligations are unavailable for investment, the fund may invest temporarily in
high quality, taxable money market instruments.


Municipal obligations are typically divided into two types:

*   GENERAL OBLIGATION BONDS, which are secured by the full faith and
   credit of the issuer and its taxing power

*   REVENUE BONDS, which are payable from the revenues derived from a
   specific revenue source, such as charges for water and sewer service or
   highway tolls

Although the fund's objective is to generate income exempt from federal income
tax, interest from some of its holdings may be subject to the federal
alternative minimum tax. In addition, the fund occasionally may invest in
taxable money market instruments.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.


EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

Dreyfus New York Municipal Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal, New York
state and New York city personal income taxes as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal, New
York state and New York city personal income taxes. When the portfolio manager
believes that acceptable New York municipal obligations are unavailable for
investment, the fund may invest in securities that may be subject to New York
state and New York city income taxes, but are free from federal income tax. When
acceptable municipal obligations are unavailable generally, the fund may invest
in high quality, taxable money market instruments.

Municipal obligations are typically divided into two types:

*   GENERAL OBLIGATION BONDS, which are secured by the full faith and
   credit of the issuer and its taxing power

*   REVENUE BONDS, which are payable from the revenues derived from a
   specific revenue source, such as charges for water and sewer service or
   highway tolls

Although the fund's objective is to generate income exempt from federal, New
York state and New York city income taxes, interest from some of its holdings
may be subject to the federal alternative minimum tax. In addition, the fund
occasionally may invest in municipal obligations that are exempt only from
federal income tax, or in taxable money market instruments.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

*   New York's economy and revenues underlying its municipal obligations
may decline

*   the fund's portfolio securities may be more sensitive to risks that are
specific to investing primarily in a single state

The fund is non-diversified, which means that a relatively high percentage of
the fund's assets may be invested in a limited number of issuers. Therefore, its
performance may be more vulnerable to changes in the market value of a single
issuer or a group of issuers.

MANAGEMENT

The investment adviser for each fund is The Dreyfus Corporation, 200 Park
Avenue, New York, New York 10166. Founded in 1947, Dreyfus manages more than
$120 billion in over 160 mutual fund portfolios. For the past fiscal year, each
fund paid Dreyfus a management fee at the annual rate of 0.20% of the fund's
average daily net assets. Dreyfus is the primary mutual fund business of Mellon
Bank Corporation, a broad-based financial services company with a bank at its
core. With more than $389 billion of assets under management and $1.9 trillion
of assets under administration and custody, Mellon provides a full range of
banking, investment and trust products and services to individuals, businesses
and institutions. Mellon is headquartered in Pittsburgh, Pennsylvania.

The Dreyfus asset management philosophy is based on the belief that discipline
and consistency are important to investment success. For each fund, Dreyfus
seeks to establish clear guidelines for portfolio management and to be
systematic in making decisions. This approach is designed to provide each fund
with a distinct, stable identity.

Dreyfus has a personal securities trading policy (the "Policy") which restricts
the personal securities transactions of its employees. Its primary purpose is to
ensure that personal trading by Dreyfus employees does not disadvantage any
Dreyfus-managed fund. Dreyfus portfolio managers and other investment personnel
who comply with the Policy's preclearance and disclosure procedures may be
permitted to purchase, sell or hold certain types of securities which also may
be or are held in the fund(s) they advise.

Concepts to understand

YEAR 2000 ISSUES: these funds could be adversely affected if the computer
systems used by Dreyfus and the funds' other service providers do not properly
process and calculate date-related information from and after January 1, 2000.

Dreyfus is working to avoid year 2000-related problems in its systems and to
obtain assurances from other service providers that they are taking similar
steps. In addition, issuers of securities in which these funds invest may be
adversely affected by year 2000-related problems. This could have an impact on
the value of a fund's investments and its share price.

Account Information

ACCOUNT POLICIES

EACH FUND IS DESIGNED for institutional investors, particularly banks, acting
for themselves or in a fiduciary, advisory, agency, custodial or similar
capacity. Fund shares may not be purchased directly by individuals, although
institutions may purchase shares for accounts maintained by individuals.
Generally, each investor will be required to open a single master account with
the fund for all purposes. In certain cases, the fund may request investors to
maintain separate master accounts for shares held by the investor (i) for its
own account, for the account of other institutions and for accounts for which
the institution acts as a fiduciary, and (ii) for accounts for which the
investor acts in some other capacity. An institution may arrange with the fund's
transfer agent for sub-accounting services and will be charged directly for the
cost of such services. Institutions purchasing Institutional shares for the
benefit of their clients may impose policies, limitations and fees which are
different from those described in this prospectus.

Buying shares

THE PRICE FOR FUND SHARES is the fund's net asset value (NAV), which is
generally calculated twice a day, at 5 p.m. and 8 p.m. for the taxable money
market funds, and 12 noon and 8 p.m. for the municipal money market funds, every
day the New York Stock Exchange, or the transfer agent (as on Good Friday) as to
Dreyfus Cash Management and Dreyfus Cash Management Plus only, is open. An order
will be priced at the next NAV calculated after the order is accepted by the
fund's transfer agent or other authorized entity. Each fund's investments are
valued based on amortized cost. As a result, portfolio securities are valued at
their acquisition cost, adjusted for discounts or premiums reflected in their
purchase price. This method of valuation is designed for the fund to be able to
price its shares at $1.00 per share.

As to Dreyfus Cash Management, Dreyfus Cash Management Plus, Dreyfus Government
Cash Management and Dreyfus Treasury Cash Management, orders in proper form
placed prior to 5:00 p.m., and payments for which are received in or converted
into Federal Funds by the fund's custodian by 6:00 p.m., will become effective
at the price determined at 5:00 p.m. on that day. In this case, shares purchased
will receive the dividend declared on that day.

As to Dreyfus Government Prime Cash Management and Dreyfus Treasury Prime Cash
Management only, orders in proper form placed prior to 3:00 p.m., and payments
for which are received in or converted into Federal Funds by the fund's
custodian by 6:00 p.m., will become effective at the price determined at 5:00
p.m. on that day. In this case, shares purchased will receive the dividend
declared on that day. Orders for shares placed between 3:00 p.m and 5:00 p.m.
will not be accepted and executed, and notice of the purchase order being
rejected will be given to the institution placing the order, and any funds
received will be returned promptly to the sending institution.

Orders effected through compatible computer facilities after 5:00 p.m., but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders in proper form effected between 5:00 p.m. and 8:00 p.m., by a means other
than a compatible computer facility, will become effective on the following
business day.

All times are Eastern time.


<PAGE 26>

As to each municipal money market fund, investors whose orders in proper form
are placed and payments for which are received in or converted into Federal
Funds by the fund's custodian, prior to 12:00 noon, will be effective at the
price determined at 12:00 noon on that day. In this case, shares purchased will
receive the dividend declared on that day.

Orders effected through a compatible computer facility after 12:00 noon, but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders effected in proper form between 12:00 noon and 8:00 p.m., by a means
other than a compatible computer facility, will become effective on the
following business day.

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

INSTITUTIONAL SHARES               $10,000,000*               NONE

*The minimum initial investment in Institutional shares is $10,000,000, unless:
(a) the investor has invested at least $10,000,000 in the aggregate among any
Dreyfus Cash Management fund and Dreyfus Institutional Short Term Treasury Fund
(including in any class of a fund); or (b) the investor has, in the opinion of
Dreyfus Institutional Services Division, adequate intent and availability of
assets to reach a future level of investment of $10,000,000 among the funds
named above.

Selling shares

INVESTORS MAY SELL (REDEEM) SHARES AT ANY TIME, by wire, telephone or compatible
computer facility. Shares will be sold at the next NAV calculated after an
investor's order is accepted by the fund's transfer agent or other authorized
entity. Any certificates representing fund shares being sold must be returned
with the redemption request. Orders will be processed promptly and investors
generally will receive the proceeds within a week.

BEFORE SELLING RECENTLY PURCHASED SHARES, please note that if the fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to eight business days or until it has collected payment.

General policies

UNLESS THE INVESTOR DECLINES TELEPHONE PRIVILEGES on the application, the
investor may be responsible for any fraudulent telephone order as long as
Dreyfus takes reasonable measures to verify the order.

EACH FUND RESERVES THE RIGHT TO:

*   refuse any purchase or exchange request that could adversely affect the
fund or its operations

*   change or discontinue its exchange privilege, or temporarily suspend
this privilege during unusual market conditions

*   change its minimum investment amounts

*   delay sending out redemption proceeds for up to seven days (generally
applies only in cases of very large redemptions, excessive trading or during
unusual market conditions)

Each fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount being redeemed is deemed
by the manager to be large enough to affect fund operations.

Account Information



<PAGE 27>

DISTRIBUTIONS AND TAXES

EACH FUND USUALLY PAYS ITS SHAREHOLDERS dividends from its net investment income
once a month, and distributes any net realized securities gains once a year.
Dividends and distributions will be reinvested in the fund unless the investor
instructs the fund otherwise. There are no fees or sales charges on
reinvestments.

DIVIDENDS AND DISTRIBUTIONS PAID by the taxable money market funds are taxable
to U.S. shareholders as ordinary income (unless the investment is in a
tax-advantaged account).

EACH MUNICIPAL MONEY MARKET FUND anticipates that, under normal market
conditions, virtually all of its income dividends will be exempt from federal
and, as to Dreyfus New York Municipal Cash Management, New York state and New
York city, personal income taxes. However, any dividends and distributions from
taxable investments are taxable as ordinary income.

The tax status of any distribution is the same regardless of how long the
investor has been in the fund and whether the investor reinvests distributions
or take them in cash.

Because each investor's tax situation is unique, the investor should consult a
professional about federal, state and local tax consequences.

Concepts to understand

DIVIDENDS: income or interest paid by the investments in a fund's portfolio, net
of expenses, passed on to fund shareholders.

DISTRIBUTIONS: income, net of expenses, passed on to fund shareholders. These
are calculated on a per-share basis: each share earns the same rate of return,
so the more fund shares you own, the higher your distribution.


SERVICES FOR FUND INVESTORS

Exchange privilege

AN INVESTOR MAY PURCHASE, in exchange for Institutional shares of any Dreyfus
Cash Management fund, Institutional shares of any other Dreyfus Cash Management
fund, or of Dreyfus Institutional Short Term Treasury Fund. Be sure to read the
current prospectus for Dreyfus Institutional Short Term Treasury Fund before
exchanging into it. An exchange may be requested in writing or by telephone. Any
new account established through an exchange will have the same privileges as the
original account (as long as they are available). There is currently no fee for
exchanges.

Dreyfus Auto-Exchange privilege

DREYFUS AUTO-EXCHANGE PRIVILEGE enables an investor to invest regularly (on a
monthly, semi-monthly, quarterly or annual basis), in exchange for Institutional
Shares of any Dreyfus Cash Management fund, in Institutional Shares of any other
Dreyfus Cash Management fund or in Dreyfus Institutional Short Term Treasury
Fund, if the investor is a shareholder in such fund. There is currently no fee
for this privilege.

Account statements

EVERY FUND INVESTOR AUTOMATICALLY RECEIVES regular account statements. Each
investor also will be sent a yearly statement detailing the tax characteristics
of any dividends and distributions the investor has received.

The Funds

Introduction

Each fund is a money market mutual fund with a separate investment portfolio.
The operations and results of a fund are unrelated to those of each other fund.
This combined prospectus has been prepared for your convenience so that you can
consider nine investment choices in one document.

As a money market fund, each fund is subject to maturity, quality and
diversification requirements designed to help it maintain a stable share price.

Generally, each fund is required to invest at least 95% of its assets in the
securities of issuers with the highest credit rating or the unrated equivalent
as determined by Dreyfus, with the remainder invested in securities with the
second-highest credit rating. Dreyfus Cash Management and Dreyfus Cash
Management Plus purchase securities with the highest credit rating only, or the
unrated equivalent. Dreyfus Government Prime Cash Management and Dreyfus
Treasury Prime Cash Management invest only in U.S. government securities.

An investment in a fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although each fund seeks
to preserve the value of your investment at $1.00 per share, it is possible to
lose money by investing in a fund.

Concepts to understand

MONEY MARKET FUND: a specific type of fund that seeks to maintain a $1.00 price
per share. Money market funds are subject to strict federal requirements and
must:

(pound) maintain an average dollar-weighted portfolio maturity of 90 days or
        less

(pound) buy individual securities that have remaining maturities of 13 months or
        less

(pound) invest only in high quality, dollar-denominated obligations

CREDIT RATING: a measure of the issuer's expected ability to make all required
interest and principal payments in a timely manner. An issuer with the highest
credit rating has a very strong degree of certainty (or safety) with respect to
making all payments. An issuer with the second-highest credit rating has a
strong capacity to make all payments, but the degree of safety is somewhat less

The Funds

<PAGE 1>


Dreyfus Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

(pound)  securities issued or guaranteed by the U.S. government or its agencies
         or instrumentalities

(pound)  certificates of deposit, time deposits, bankers' acceptances, and other
         short-term securities issued by domestic banks or London branches of
         domestic banks

(pound)  repurchase agreements, including tri-party repurchase agreements

(pound)  high grade commercial paper, and other short-term corporate
         obligations, including those with floating rates of interest

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

(pound)  the risks generally associated with concentrating investments in the
         banking industry, such as interest rate risk, credit risk and
         regulatory developments relating to the banking industry

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

What this fund is -- and isn't



This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them.  Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Administrative shares, and to compensate Dreyfus for advertising
and marketing Administrative shares, and for providing account service and
maintenance. Dreyfus and the distributor may pay all or part of this fee to
institutions which have purchased Administrative shares for the benefit of
others. Because this fee is paid out of the fund's assets on an ongoing basis,
over time it will increase the cost of your investment and may cost you more
than is payable with other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement upon at least 90 days' prior
notice to investors, but has committed not to do so at least through May 31,
2000.


Dreyfus Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

(pound)  securities issued or guaranteed by the U.S. government or its agencies
         or instrumentalities

(pound)  certificates of deposit, time deposits, bankers' acceptances and other
         short-term securities issued by domestic banks or foreign banks (or
         thrifts) or their subsidiaries or branches

(pound)  repurchase agreements, including tri-party repurchase agreements

(pound)  asset-backed securities

(pound)  domestic and dollar-denominated foreign commercial paper, and other
         short-term corporate obligations, including those with floating or
         variable rates of interest

(pound)  dollar-denominated obligations issued or guaranteed by one or more
         foreign governments or any of their political subdivisions or
         agencies

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

(pound)  the risks generally associated with concentrating investments in the
         banking industry, such as interest rate risk, credit risk and
         regulatory developments relating to the banking industry

(pound)  the risks generally associated with dollar-denominated foreign
         investments, such as economic and political developments, seizure or
         nationalization of deposits, imposition of taxes or other restrictions
         on the payment of principal and interest

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund invests in securities issued or guaranteed as to
principal and interest by the U.S. government or its agencies or
instrumentalities, and repurchase agreements (including tri-party repurchase
agreements) in respect of these securities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.


Certain U.S. government agency securities are backed by the right of the issuer
to borrow from the U.S. Treasury, or are supported only by the credit of the
issuer or instrumentality. While the U.S. government provides financial support
to U.S. government-sponsored agencies or instrumentalities, no assurance can be
given that it will always do so.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.


Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Administrative shares, and to compensate Dreyfus for advertising
and marketing Administrative shares, and for providing account service and
maintenance. Dreyfus and the distributor may pay all or part of this fee to
institutions which have purchased Administrative shares for the benefit of
others. Because this fee is paid out of the fund's assets on an ongoing basis,
over time it will increase the cost of your investment and may cost you more
than is payable with other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement upon at least 90 days' prior
notice to investors, but has committed not to do so at least through May 31,
2000.

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund only invests in securities issued or guaranteed as
to principal and interest by the U.S. government, and repurchase agreements
(including tri-party repurchase agreements) in respect of these securities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

guarantee of future results.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

Dreyfus Treasury Prime Cash Management


<PAGE 13>

Dreyfus Tax Exempt Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal personal
income tax as is consistent with the preservation of capital and the maintenance
of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal personal
income tax. When the portfolio manager believes that acceptable municipal
obligations are unavailable for investment, the fund may invest temporarily in
high quality, taxable money market instruments.

Municipal obligations are typically divided into two types:

(pound)  GENERAL OBLIGATION BONDS, which are secured by the full faith and
         credit of the issuer and its taxing power

(pound)  REVENUE BONDS, which are payable from the revenues derived from a
         specific revenue source, such as charges for water and sewer service or
         highway tolls

While the fund is permitted to invest up to 20% of its assets in municipal
obligations that pay interest that may be subject to the federal alternative
minimum tax, the fund currently is managed so that income paid by the fund will
not be subject to the federal alternative minimum tax.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.


EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Administrative shares, and to compensate Dreyfus for advertising
and marketing Administrative shares, and for providing account service and
maintenance. Dreyfus and the distributor may pay all or part of this fee to
institutions which have purchased Administrative shares for the benefit of
others. Because this fee is paid out of the fund's assets on an ongoing basis,
over time it will increase the cost of your investment and may cost you more
than is payable with other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement upon at least 90 days' prior
notice to investors, but has committed not to do so at least through May 31,
2000.


Dreyfus Municipal Cash Management Plus

<PAGE 17>

Dreyfus New York Municipal Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal, New York
state and New York city personal income taxes as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal, New
York state and New York city personal income taxes. When the portfolio manager
believes that acceptable New York municipal obligations are unavailable for
investment, the fund may invest in securities that may be subject to New York
state and New York city income taxes, but are free from federal income tax. When
acceptable municipal obligations are unavailable generally, the fund may invest
in high quality, taxable money market instruments.

Municipal obligations are typically divided into two types:

(pound)  GENERAL OBLIGATION BONDS, which are secured by the full faith and
         credit of the issuer and its taxing power

(pound)  REVENUE BONDS, which are payable from the revenues derived from a
         specific revenue source, such as charges for water and sewer service or
         highway tolls

Although the fund's objective is to generate income exempt from federal, New
York state and New York city income taxes, interest from some of its holdings
may be subject to the federal alternative minimum tax. In addition, the fund
occasionally may invest in municipal obligations that are exempt only from
federal income tax, or in taxable money market instruments.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

(pound)  New York's economy and revenues underlying its municipal obligations
         may decline

(pound)  the fund's portfolio securities may be more sensitive to risks that are
         specific to investing primarily in a single state

The fund is non-diversified, which means that a relatively high percentage of
the fund's assets may be invested in a limited number of issuers. Therefore, its
performance may be more vulnerable to changes in the market value of a single
issuer or a group of issuers.

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Administrative share class performance
from year to year. The second table averages the fund's performance over time.
Both tables assume reinvestment of dividends. Of course, past performance is no
guarantee of future results.

MANAGEMENT

The investment adviser for each fund is The Dreyfus Corporation, 200 Park
Avenue, New York, New York 10166. Founded in 1947, Dreyfus manages more than
$120 billion in over 160 mutual fund portfolios. For the past fiscal year, each
fund paid Dreyfus a management fee at the annual rate of 0.20% of the fund's
average daily net assets. Dreyfus is the primary mutual fund business of Mellon
Bank Corporation, a broad-based financial services company with a bank at its
core. With more than $389 billion of assets under management and $1.9 trillion
of assets under administration and custody, Mellon provides a full range of
banking, investment and trust products and services to individuals, businesses
and institutions. Mellon is headquartered in Pittsburgh, Pennsylvania.

The Dreyfus asset management philosophy is based on the belief that discipline
and consistency are important to investment success. For each fund, Dreyfus
seeks to establish clear guidelines for portfolio management and to be
systematic in making decisions. This approach is designed to provide each fund
with a distinct, stable identity.

Dreyfus has a personal securities trading policy (the "Policy") which restricts
the personal securities transactions of its employees. Its primary purpose is to
ensure that personal trading by Dreyfus employees does not disadvantage any
Dreyfus-managed fund. Dreyfus portfolio managers and other investment personnel
who comply with the Policy's preclearance and disclosure procedures may be
permitted to purchase, sell or hold certain types of securities which also may
be or are held in the fund(s) they advise.

Concepts to understand

YEAR 2000 ISSUES: these funds could be adversely affected if the computer
systems used by Dreyfus and the funds' other service providers do not properly
process and calculate date-related information from and after January 1, 2000.

Dreyfus is working to avoid year 2000-related problems in its systems and to
obtain assurances from other service providers that they are taking similar
steps. In addition, issuers of securities in which these funds invest may be
adversely affected by year 2000-related problems. This could have an impact on
the value of a fund's investments and its share price.

Account Information

ACCOUNT POLICIES

EACH FUND IS DESIGNED for institutional investors, particularly banks, acting
for themselves or in a fiduciary, advisory, agency, custodial or similar
capacity. Fund shares may not be purchased directly by individuals, although
institutions may purchase shares for accounts maintained by individuals.
Generally, each investor will be required to open a single master account with
the fund for all purposes. In certain cases, the fund may request investors to
maintain separate master accounts for shares held by the investor (i) for its
own account, for the account of other institutions and for accounts for which
the institution acts as a fiduciary, and (ii) for accounts for which the
investor acts in some other capacity. An institution may arrange with the fund's
transfer agent for sub-accounting services and will be charged directly for the
cost of such services. Institutions purchasing Administrative shares for the
benefit of their clients may impose policies, limitations and fees which are
different from those described in this prospectus.

Buying shares

THE PRICE FOR FUND SHARES is the fund's net asset value (NAV), which is
generally calculated twice a day, at 5 p.m. and 8 p.m. for the taxable money
market funds, and 12 noon and 8 p.m. for the municipal money market funds, every
day the New York Stock Exchange, or the transfer agent (as on Good Friday) as to
Dreyfus Cash Management and Dreyfus Cash Management Plus only, is open. An order
will be priced at the next NAV calculated after the order is accepted by the
fund's transfer agent or other authorized entity. Each fund's investments are
valued based on amortized cost. As a result, portfolio securities are valued at
their acquisition cost, adjusted for discounts or premiums reflected in their
purchase price. This method of valuation is designed for the fund to be able to
price its shares at $1.00 per share.

As to Dreyfus Cash Management, Dreyfus Cash Management Plus, Dreyfus Government
Cash Management and Dreyfus Treasury Cash Management, orders in proper form
placed prior to 5:00 p.m., and payments for which are received in or converted
into Federal Funds by the fund's custodian by 6:00 p.m., will become effective
at the price determined at 5:00 p.m. on that day. In this case, shares purchased
will receive the dividend declared on that day.

As to Dreyfus Government Prime Cash Management and Dreyfus Treasury Prime Cash
Management only, orders in proper form placed prior to 3:00 p.m., and payments
for which are received in or converted into Federal Funds by the fund's
custodian by 6:00 p.m., will become effective at the price determined at 5:00
p.m. on that day. In this case, shares purchased will receive the dividend
declared on that day. Orders for shares placed between 3:00 p.m and 5:00 p.m.
will not be accepted and executed, and notice of the purchase order being
rejected will be given to the institution placing the order, and any funds
received will be returned promptly to the sending institution.

Orders effected through compatible computer facilities after 5:00 p.m., but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders in proper form effected between 5:00 p.m. and 8:00 p.m., by a means other
than a compatible computer facility, will become effective on the following
business day.

All times are Eastern time.




<PAGE 26>

As to each municipal money market fund, investors whose orders in proper form
are placed and payments for which are received in or converted into Federal
Funds by the fund's custodian, prior to 12:00 noon, will be effective at the
price determined at 12:00 noon on that day. In this case, shares purchased will
receive the dividend declared on that day.

Orders effected through a compatible computer facility after 12:00 noon, but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders effected in proper form between 12:00 noon and 8:00 p.m., by a means
other than a compatible computer facility, will become effective on the
following business day.

All times are Eastern time.

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

ADMINISTRATIVE SHARES              $10,000,000*               NONE

*The minimum initial investment in Administrative shares is $10,000,000, unless:
(a) the investor has invested at least $10,000,000 in the aggregate among any
Dreyfus Cash Management fund and Dreyfus Institutional Short Term Treasury Fund
(including in any class of a fund); or (b) the investor has, in the opinion of
Dreyfus Institutional Services Division, adequate intent and availability of
assets to reach a future level of investment of $10,000,000 among the funds
named above.

Selling shares

INVESTORS MAY SELL (REDEEM) SHARES AT ANY TIME, by wire, telephone or compatible
computer facility. Shares will be sold at the next NAV calculated after an
investor's order is accepted by the fund's transfer agent or other authorized
entity. Any certificates representing fund shares being sold must be returned
with the redemption request. Orders will be processed promptly and investors
generally will receive the proceeds within a week.

BEFORE SELLING RECENTLY PURCHASED SHARES, please note that if the fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to eight business days or until it has collected payment.

General policies

UNLESS THE INVESTOR DECLINES TELEPHONE PRIVILEGES on the application, the
investor may be responsible for any fraudulent telephone order as long as
Dreyfus takes reasonable measures to verify the order.

EACH FUND RESERVES THE RIGHT TO:

(pound)  refuse any purchase or exchange request that could adversely affect the
         fund or its operations

(pound)  change or discontinue its exchange privilege, or temporarily suspend
         this privilege during unusual market conditions

(pound)  change its minimum investment amounts

(pound)  delay sending out redemption proceeds for up to seven days (generally
         applies only in cases of very large redemptions, excessive trading or
         during unusual market conditions)

Each fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount being redeemed is deemed
by the manager to be large enough to affect fund operations.

Account Information



<PAGE 27>

DISTRIBUTIONS AND TAXES

EACH FUND USUALLY PAYS ITS SHAREHOLDERS dividends from its net investment income
once a month, and distributes any net realized securities gains once a year.
Dividends and distributions will be reinvested in the fund unless the investor
instructs the fund otherwise. There are no fees or sales charges on
reinvestments.

DIVIDENDS AND DISTRIBUTIONS PAID by the taxable money market funds are taxable
to U.S. shareholders as ordinary income (unless the investment is in a
tax-advantaged account).

EACH MUNICIPAL MONEY MARKET FUND anticipates that, under normal market
conditions, virtually all of its income dividends will be exempt from federal
and, as to Dreyfus New York Municipal Cash Management, New York state and New
York city, personal income taxes. However, any dividends and distributions from
taxable investments are taxable as ordinary income.

The tax status of any distribution is the same regardless of how long the
investor has been in the fund and whether the investor reinvests distributions
or take them in cash.

Because each investor's tax situation is unique, the investor should consult a
professional about federal, state and local tax consequences.

Concepts to understand

DIVIDENDS: income or interest paid by the investments in a fund's portfolio, net
of expenses, passed on to fund shareholders.

DISTRIBUTIONS: income, net of expenses, passed on to fund shareholders. These
are calculated on a per-share basis: each share earns the same rate of return,
so the more fund shares you own, the higher your distribution.


SERVICES FOR FUND INVESTORS

Exchange privilege

AN INVESTOR MAY PURCHASE, in exchange for Administrative shares of any Dreyfus
Cash Management fund, Administrative shares of any other Dreyfus Cash Management
fund, or of Dreyfus Institutional Short Term Treasury Fund. Be sure to read the
current prospectus for Dreyfus Institutional Short Term Treasury Fund before
exchanging into it. An exchange may be requested in writing or by telephone. Any
new account established through an exchange will have the same privileges as the
original account (as long as they are available). There is currently no fee for
exchanges.

Dreyfus Auto-Exchange privilege

DREYFUS AUTO-EXCHANGE PRIVILEGE enables an investor to invest regularly (on a
monthly, semi-monthly, quarterly or annual basis), in exchange for
Administrative shares of any Dreyfus Cash Management fund, in Administrative
shares of any other Dreyfus Cash Management fund or in Dreyfus Institutional
Short Term Treasury Fund, if the investor is a shareholder in such fund. There
is currently no fee for this privilege.

Account statements

EVERY FUND INVESTOR AUTOMATICALLY RECEIVES regular account statements. Each
investor also will be sent a yearly statement detailing the tax characteristics
of any dividends and distributions the investor has received.

MORE INFORMATION ON EACH FUND CAN BE FOUND IN THE FUND'S CURRENT
ANNUAL/SEMIANNUAL REPORT. SEE BACK COVER.

Introduction

Each fund is a money market mutual fund with a separate investment portfolio.
The operations and results of a fund are unrelated to those of each other fund.
This combined prospectus has been prepared for your convenience so that you can
consider nine investment choices in one document.

As a money market fund, each fund is subject to maturity, quality and
diversification requirements designed to help it maintain a stable share price.

Generally, each fund is required to invest at least 95% of its assets in the
securities of issuers with the highest credit rating or the unrated equivalent
as determined by Dreyfus, with the remainder invested in securities with the
second-highest credit rating. Dreyfus Cash Management and Dreyfus Cash
Management Plus purchase securities with the highest credit rating only, or the
unrated equivalent. Dreyfus Government Prime Cash Management and Dreyfus
Treasury Prime Cash Management invest only in U.S. government securities.

An investment in a fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although each fund seeks
to preserve the value of your investment at $1.00 per share, it is possible to
lose money by investing in a fund.

Concepts to understand

MONEY MARKET FUND: a specific type of fund that seeks to maintain a $1.00 price
per share. Money market funds are subject to strict federal requirements and
must:

(pound) maintain an average dollar-weighted portfolio maturity of 90 days or
        less

(pound) buy individual securities that have remaining maturities of 13 months or
        less

(pound) invest only in high quality, dollar-denominated obligations

CREDIT RATING: a measure of the issuer's expected ability to make all required
interest and principal payments in a timely manner. An issuer with the highest
credit rating has a very strong degree of certainty (or safety) with respect to
making all payments. An issuer with the second-highest credit rating has a
strong capacity to make all payments, but the degree of safety is somewhat less

The Funds

<PAGE 1>


Dreyfus Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

(pound)  securities issued or guaranteed by the U.S. government or its agencies
         or instrumentalities

(pound)  certificates of deposit, time deposits, bankers' acceptances, and other
         short-term securities issued by domestic banks or London branches of
         domestic banks

(pound)  repurchase agreements, including tri-party repurchase agreements

(pound)  high grade commercial paper, and other short-term corporate
         obligations, including those with floating rates of interest

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

(pound)  the risks generally associated with concentrating investments in the
         banking industry, such as interest rate risk, credit risk and
         regulatory developments relating to the banking industry

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Investor share class performance from year
to year. The second table averages the fund's performance over time. Both tables
assume reinvestment of dividends. Of course, past performance is no guarantee of
future results.

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.


EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Investor shares, and to compensate Dreyfus for advertising and
marketing Investor shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of the fee to institutions
which have purchased Investor shares for the benefit of others. Because this
fee is paid out of the fund's assets on an ongoing basis, over time it will
increase the cost of your investment and may cost you more than is payable with
other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement upon at least 90 days' prior
notice to investors, but has committed not to do so at least through May 31,
2000.

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

(pound)  securities issued or guaranteed by the U.S. government or its agencies
         or instrumentalities

(pound)  certificates of deposit, time deposits, bankers' acceptances and other
         short-term securities issued by domestic banks or foreign banks (or
         thrifts) or their subsidiaries or branches

(pound)  repurchase agreements, including tri-party repurchase agreements

(pound)  asset-backed securities

(pound)  domestic and dollar-denominated foreign commercial paper, and other
         short-term corporate obligations, including those with floating or
         variable rates of interest

(pound)  dollar-denominated obligations issued or guaranteed by one or more
         foreign governments or any of their political subdivisions or agencies

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

(pound)  the risks generally associated with concentrating investments in the
         banking industry, such as interest rate risk, credit risk and
         regulatory developments relating to the banking industry

(pound)  the risks generally associated with dollar-denominated foreign
         investments, such as economic and political developments, seizure or
         nationalization of deposits, imposition of taxes or other restrictions
         on the payment of principal and interest

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund invests in securities issued or guaranteed as to
principal and interest by the U.S. government or its agencies or
instrumentalities, and repurchase agreements (including tri-party repurchase
agreements) in respect of these securities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.


Certain U.S. government agency securities are backed by the right of the issuer
to borrow from the U.S. Treasury, or are supported only by the credit of the
issuer or instrumentality. While the U.S. government provides financial support
to U.S. government-sponsored agencies or instrumentalities, no assurance can be
given that it will always do so.

the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them.  Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Investor shares, and to compensate Dreyfus for advertising and
marketing Investor shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of the fee to institutions which
have purchased Investor shares for the benefit of others. Because this fee is
paid out of the fund's assets on an ongoing basis, over time it will increase
the cost of your investment and may cost you more than is payable with other
types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement upon at least 90 days' prior
notice to investors, but has committed not to do so at least through May 31,
2000.


Dreyfus Treasury Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund only invests in securities issued or guaranteed as
to principal and interest by the U.S. government.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

Dreyfus Treasury Prime Cash Management


<PAGE 13>

Dreyfus Tax Exempt Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal personal
income tax as is consistent with the preservation of capital and the maintenance
of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal personal
income tax. When the portfolio manager believes that acceptable municipal
obligations are unavailable for investment, the fund may invest temporarily in
high quality, taxable money market instruments.

Municipal obligations are typically divided into two types:

(pound)  GENERAL OBLIGATION BONDS, which are secured by the full faith and
         credit of the issuer and its taxing power

(pound)  REVENUE BONDS, which are payable from the revenues derived from a
         specific revenue source, such as charges for water and sewer service or
         highway tolls


MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

         specific revenue source, such as charges for water and sewer service or
         highway tolls

Although the fund's objective is to generate income exempt from federal income
tax, interest from some of its holdings may be subject to the federal
alternative minimum tax. In addition, the fund occasionally may invest in
taxable money market instruments.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Investor shares, and to compensate Dreyfus for advertising and
marketing Investor shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of the fee to institutions which
have purchased Investor shares for the benefit of others. Because this fee is
paid out of the fund's assets on an ongoing basis, over time it will increase
the cost of your investment and may cost you more than is payable with other
types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement upon at least 90 days' prior
notice to investors, but has committed not to do so at least through May 31,
2000.


Dreyfus Municipal Cash Management Plus

<PAGE 17>

Dreyfus New York Municipal Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal, New York
state and New York city personal income taxes as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal, New
York state and New York city personal income taxes. When the portfolio manager
believes that acceptable New York municipal obligations are unavailable for
investment, the fund may invest in securities that may be subject to New York
state and New York city income taxes, but are free from federal income tax.
When acceptable municipal obligations are unavailable generally the fund may
invest in high quality, taxable money market instruments.

Municipal obligations are typically divided into two types:

(pound)  GENERAL OBLIGATION BONDS, which are secured by the full faith and
         credit of the issuer and its taxing power

(pound)  REVENUE BONDS, which are payable from the revenues derived from a
         specific revenue source, such as charges for water and sewer service or
         highway tolls

Although the fund's objective is to generate income exempt from federal, New
York state and New York city income taxes, interest from some of its holdings
may be subject to the federal alternative minimum tax. In addition, the fund
occasionally may invest in municipal obligations that are exempt only from
federal income tax or in taxable money market instruments.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

(pound)  interest rates could rise sharply, causing the fund's share price to
         drop

(pound)  any of the fund's holdings could have its credit rating downgraded or
         could default

(pound)  New York's economy and revenues underlying its municipal obligations
         may decline

(pound)  the fund's portfolio securities may be more sensitive to risks that are
specific to investing primarily in a single state

The fund is non-diversified, which means that a relatively high percentage of
the fund's assets may be invested in a limited number of issuers. Therefore, its
performance may be more vulnerable to changes in the market value of a single
issuer or a group of issuers.

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Investor share class performance from year
to year. The second table averages the fund's performance over time. Both tables
assume reinvestment of dividends. Of course, past performance is no guarantee of
future results.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

Dreyfus New York Municipal Cash Management

MANAGEMENT

The investment adviser for each fund is The Dreyfus Corporation, 200 Park
Avenue, New York, New York 10166. Founded in 1947, Dreyfus manages more than
$120 billion in over 160 mutual fund portfolios. For the past fiscal year, each
fund paid Dreyfus a  management fee at the annual rate of 0.20% of the fund's
average daily net assets. Dreyfus is the primary mutual fund business of Mellon
Bank Corporation, a broad-based financial services company with a bank at its
core. With more than $389 billion of assets under management and $1.9 trillion
of assets under administration and custody, Mellon provides a full range of
banking, investment and trust products and services to individuals, businesses
and institutions. Mellon is headquartered in Pittsburgh, Pennsylvania.

The Dreyfus asset management philosophy is based on the belief that discipline
and consistency are important to investment success. For each fund, Dreyfus
seeks to establish clear guidelines for portfolio management and to be
systematic in making decisions. This approach is designed to provide each fund
with a distinct, stable identity.

Dreyfus has a personal securities trading policy (the "Policy") which restricts
the personal securities transactions of its employees. Its primary purpose is to
ensure that personal trading by Dreyfus employees does not disadvantage any
Dreyfus-managed fund. Dreyfus portfolio managers and other investment personnel
who comply with the Policy's preclearance and disclosure procedures may be
permitted to purchase, sell or hold certain types of securities which also may
be or are held in the fund(s) they advise.

Concepts to understand

YEAR 2000 ISSUES: these funds could be adversely affected if the computer
systems used by Dreyfus and the funds' other service providers do not properly
process and calculate date-related information from and after January 1, 2000.

Dreyfus is working to avoid year 2000-related problems in its systems and to
obtain assurances from other service providers that they are taking similar
steps. In addition, issuers of securities in which these funds invest may be
adversely affected by year 2000-related problems. This could have an impact on
the value of a fund's investments and its share price.

Account Information

ACCOUNT POLICIES

EACH FUND IS DESIGNED for institutional investors, particularly banks, acting
for themselves or in a fiduciary, advisory, agency, custodial or similar
capacity. Fund shares may not be purchased directly by individuals, although
institutions may purchase shares for accounts maintained by individuals.
Generally, each investor will be required to open a single master account with
the fund for all purposes. In certain cases, the fund may request investors to
maintain separate master accounts for shares held by the investor (i) for its
own account, for the account of other institutions and for accounts for which
the institution acts as a fiduciary, and (ii) for accounts for which the
investor acts in some other capacity. An institution may arrange with the fund's
transfer agent for sub-accounting services and will be charged directly for the
cost of such services. Institutions purchasing Investor shares for the benefit
of their clients may impose policies, limitations and fees which are different
from those described in this prospectus.

Buying shares

THE PRICE FOR FUND SHARES is the fund's net asset value (NAV), which is
generally calculated twice a day, at 5 p.m. and 8 p.m. for the taxable money
market funds, and 12 noon and 8 p.m. for the municipal money market funds, every
day the New York Stock Exchange, or the transfer agent (as on Good Friday) as to
Dreyfus Cash Management and Dreyfus Cash Management Plus only, is open. An order
will be priced at the next NAV calculated after the order is accepted by the
fund's transfer agent or other authorized entity. Each fund's investments are
valued based on amortized cost. As a result, portfolio securities are valued at
their acquisition cost, adjusted for discounts or premiums reflected in their
purchase price. This method of valuation is designed for the fund to be able to
price its shares at $1.00 per share.

As to Dreyfus Cash Management, Dreyfus Cash Management Plus, Dreyfus Government
Cash Management and Dreyfus Treasury Cash Management, orders in proper form
placed prior to 5:00 p.m., and payments for which are received in or converted
into Federal Funds by the fund's custodian by 6:00 p.m., will become effective
at the price determined at 5:00 p.m. on that day. In this case, shares purchased
will receive the dividend declared on that day.

As to Dreyfus Government Prime Cash Management and Dreyfus Treasury Prime Cash
Management only, orders in proper form placed prior to 3:00 p.m., and payments
for which are received in or converted into Federal Funds by the fund's
custodian by 6:00 p.m., will become effective at the price determined at 5:00
p.m. on that day. In this case, shares purchased will receive the dividend
declared on that day. Orders for shares placed between 3:00 p.m and 5:00 p.m.
will not be accepted and executed, and notice of the purchase order being
rejected will be given to the institution placing the order, and any funds
received will be returned promptly to the sending institution.

Orders effected through compatible computer facilities after 5:00 p.m., but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders in proper form effected between 5:00 p.m. and 8:00 p.m., by a means other
than a compatible computer facility, will become effective on the following
business day.

All times are Eastern time.

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

INVESTOR SHARES                   $10,000,000*               NONE

*The minimum initial investment in Investor shares is $10,000,000, unless: (a)
the investor has invested at least $10,000,000 in the aggregate among any
Dreyfus Cash Management fund and Dreyfus Institutional Short Term Treasury Fund
(including in any class of a fund); or (b) the investor has, in the opinion of
Dreyfus Institutional Services Division, adequate intent and availability of
assets to reach a future level of investment of $10,000,000 among the funds
named above.

Selling shares

INVESTORS MAY SELL (REDEEM) SHARES AT ANY TIME, by wire, telephone or compatible
computer facility. Shares will be sold at the next NAV calculated after an
investor's order is accepted by the fund's transfer agent or other authorized
entity. Any certificates representing fund shares being sold must be returned
with the redemption request. Orders will be processed promptly and investors
generally will receive the proceeds within a week.

BEFORE SELLING RECENTLY PURCHASED SHARES, please note that if the fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to eight business days or until it has collected payment.

General policies

UNLESS THE INVESTOR DECLINES TELEPHONE PRIVILEGES on the application, the
investor may be responsible for any fraudulent telephone order as long as
Dreyfus takes reasonable measures to verify the order.

EACH FUND RESERVES THE RIGHT TO:

(pound)  refuse any purchase or exchange request that could adversely affect the
         fund or its operations

(pound)  change or discontinue its exchange privilege, or temporarily suspend
         this privilege during unusual market conditions

(pound)  change its minimum investment amounts

(pound)  delay sending out redemption proceeds for up to seven days (generally
         applies only in cases of very large redemptions, excessive trading or
         during unusual market conditions)

Each fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount being redeemed is deemed
by the manager to be large enough to affect fund operations.

Account Information



<PAGE 27>

DISTRIBUTIONS AND TAXES

EACH FUND USUALLY PAYS ITS SHAREHOLDERS dividends from its net investment income
once a month, and distributes any net realized securities gains once a year.
Dividends and distributions will be reinvested in the fund unless the investor
instructs the fund otherwise. There are no fees or sales charges on
reinvestments.

DIVIDENDS AND DISTRIBUTIONS PAID by the taxable money market funds are taxable
to U.S. shareholders as ordinary income (unless the investment is in a
tax-advantaged account).

EACH MUNICIPAL MONEY MARKET FUND anticipates that, under normal market
conditions, virtually all of its income dividends will be exempt from federal
and, as to Dreyfus New York Municipal Cash Management, New York state and New
York city, personal income taxes. However, any dividends and distributions from
taxable investments are taxable as ordinary income.

The tax status of any distribution is the same regardless of how long the
investor has been in the fund and whether the investor reinvests distributions
or take them in cash.

Because each investor's tax situation is unique, the investor should consult a
professional about federal, state and local tax consequences.

Concepts to understand

DIVIDENDS: income or interest paid by the investments in a fund's portfolio, net
of expenses, passed on to fund shareholders.

DISTRIBUTIONS: income, net of expenses, passed on to fund shareholders. These
are calculated on a per-share basis:  each share earns the same rate of return,
so the more fund shares you own, the higher your distribution.

SERVICES FOR FUND INVESTORS

Exchange privilege

AN INVESTOR MAY PURCHASE, in exchange for Investor shares of any Dreyfus Cash
Management fund, Investor shares of any other Dreyfus Cash Management fund, or
of Dreyfus Institutional Short Term Treasury Fund. Be sure to read the current

into it. An exchange may be requested in writing or by telephone. Any new
account established through an exchange will have the same privileges as the
original account (as long as they are available). There is currently no fee for
exchanges.

Dreyfus Auto-Exchange privilege

DREYFUS AUTO-EXCHANGE PRIVILEGE enables an investor to invest regularly (on a
monthly, semi-monthly, quarterly or annual basis), in exchange for Investor
shares of any Dreyfus Cash Management fund, in Investor shares of any other
Dreyfus Cash Management fund or in Dreyfus Institutional Short Term Treasury
Fund, if the investor is a shareholder in such fund. There is currently no fee
for this privilege.

Account statements

EVERY FUND INVESTOR AUTOMATICALLY RECEIVES regular account statements. Each
investor also will be sent a yearly statement detailing the tax characteristics
of any dividends and distributions the investor has received.

MORE INFORMATION ON EACH FUND CAN BE FOUND IN THE FUND'S CURRENT
ANNUAL/SEMIANNUAL REPORT. SEE BACK COVER.

Introduction

Each fund is a money market mutual fund with a separate investment portfolio.
The operations and results of a fund are unrelated to those of each other fund.
This combined prospectus has been prepared for your convenience so that you can
consider nine investment choices in one document.

As a money market fund, each fund is subject to maturity, quality and
diversification requirements designed to help it maintain a stable share price.

Generally, each fund is required to invest at least 95% of its assets in the
securities of issuers with the highest credit rating or the unrated equivalent
as determined by Dreyfus, with the remainder invested in securities with the
second-highest credit rating. Dreyfus Cash Management and Dreyfus Cash
Management Plus purchase securities with the highest credit rating only, or the
unrated equivalent. Dreyfus Government Prime Cash Management and Dreyfus
Treasury Prime Cash Management invest only in U.S. government securities.

An investment in a fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although each fund seeks
to preserve the value of your investment at $1.00 per share, it is possible to
lose money by investing in a fund.

Concepts to understand

MONEY MARKET FUND: a specific type of fund that seeks to maintain a $1.00 price
per share. Money market funds are subject to strict federal requirements and
must:

*  maintain an average dollar-weighted portfolio maturity of 90 days or
less

*  buy individual securities that have remaining maturities of 13 months or
less

*  invest only in high quality, dollar-denominated obligations

CREDIT RATING: a measure of the issuer's expected ability to make all required
interest and principal payments in a timely manner. An issuer with the highest
credit rating has a very strong degree of certainty (or safety) with respect to
making all payments. An issuer with the second-highest credit rating has a
strong capacity to make all payments, but the degree of safety is somewhat less

The Funds

<PAGE 1>


Dreyfus Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

*  securities issued or guaranteed by the U.S. government or its agencies
   or instrumentalities

*  certificates of deposit, time deposits, bankers' acceptances, and other
   short-term securities issued by domestic banks or London branches of domestic
   banks

*  repurchase agreements, including tri-party repurchase agreements

*  high grade commercial paper, and other short-term corporate
   obligations, including those with floating rates of interest

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

*   the risks generally associated with concentrating investments in the
banking industry, such as interest rate risk, credit risk and regulatory
developments relating to the banking industry

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.



<PAGE 2>

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Participant share class performance from
year to year. The second table averages the fund's performance over time. Both
tables assume reinvestment of dividends. Of course, past performance is no
guarantee of future results.
- --------------------------------------------------------------------------------


Year-by-year total return AS OF 12/31 EACH YEAR (%)

WORST QUARTER:                   Q4 '98                          +1.19%


The 7-day yield for Participant shares on 12/31/98 was 4.61%. Institutions may
call toll-free 1-800-346-3621 for the current yield for Participant shares.
Individuals or entities for whom institutions may purchase or redeem shares
should call the institution directly.

                                                              inception
         1 Year                                              (11/21/96)

         5.09%                                                  5.11%



What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.


An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.
- --------------------------------------------------------------------------------

Rule 12b-1 fee                                                          0.40%

</TABLE>


This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Participant shares, and to compensate Dreyfus for advertising and
marketing Participant shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of this fee to institutions
which have purchased Participant shares for the benefit of others. Because this
fee is paid out of the fund's assets on an ongoing basis, over time it will
increase the cost of your investment and may cost you more than is payable with
other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement at any time upon at least 90
days' prior notice to investors, but has committed not to do so at least through
May 31, 2000.

the fund invests in a diversified portfolio of high quality, short-term debt

   short-term securities issued by domestic banks or foreign banks (or thrifts)
   or their subsidiaries or branches

*  repurchase agreements, including tri-party repurchase agreements

*  asset-backed securities

*  domestic and dollar-denominated foreign commercial paper, and other
   short-term corporate obligations, including those with floating or variable
   rates of interest

*  dollar-denominated obligations issued or guaranteed by one or more
   foreign governments or any of their political subdivisions or agencies

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

*   the risks generally associated with concentrating investments in the
banking industry, such as interest rate risk, credit risk and regulatory
developments relating to the banking industry

*   the risks generally associated with dollar-denominated foreign
investments, such as economic and political developments, seizure or
nationalization of deposits, imposition of taxes or other restrictions on the
payment of principal and interest

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.


EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Participant shares, and to compensate Dreyfus for advertising and
marketing Participant shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of this fee to institutions
which have purchased Participant shares for the benefit of others. Because this
fee is paid out of the fund's assets on an ongoing basis, over time it will
increase the cost of your investment and may cost you more than is payable with
other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement at any time upon at least 90
days' prior notice to investors, but has committed not to do so at least through
May 31, 2000.


Dreyfus Cash Management Plus

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund invests in securities issued or guaranteed as to
principal and interest by the U.S. government or its agencies or
instrumentalities, and repurchase agreements (including tri-party repurchase
agreements) in respect of these securities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.


Certain U.S. government agency securities are backed by the right of the issuer
to borrow from the U.S. Treasury, or are supported only by the credit of the
issuer or instrumentality. While the U.S. government provides financial support
to U.S. government-sponsored agencies or instrumentalities, no assurance can be
given that it will always do so.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Participant shares, and to compensate Dreyfus for advertising and
marketing Participant shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of this fee to institutions
which have purchased Participant shares for the benefit of others. Because this
fee is paid out of the fund's assets on an ongoing basis, over time it will
increase the cost of your investment and may cost you more than is payable with
other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement at any time upon at least 90
days' prior notice to investors, but has committed not to do so at least through
May 31, 2000.

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund only invests in securities issued or guaranteed as
to principal and interest by the U.S. government.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Participant share class performance from
year to year. The second table averages the fund's performance over time. Both

guarantee of future results.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.


EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

Dreyfus Treasury Prime Cash Management

<PAGE 13>

Dreyfus Tax Exempt Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income exempt from federal personal
income tax as is consistent with the preservation of capital and the maintenance
of liquidity.

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal personal
income tax. When the portfolio manager believes that acceptable municipal
obligations are unavailable for investment, the fund may invest temporarily in
high quality, taxable money market instruments.

Municipal obligations are typically divided into two types:

*   GENERAL OBLIGATION BONDS, which are secured by the full faith and
   credit of the issuer and its taxing power

*   REVENUE BONDS, which are payable from the revenues derived from a
   specific revenue source, such as charges for water and sewer service or
   highway tolls

While the fund is permitted to invest up to 20% of its assets in municipal
obligations that pay interest that may be subject to the federal alternative
minimum tax, the fund currently is managed so that income paid by the fund will
not be subject to the federal alternative minimum tax.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

To pursue this goal, the fund normally invests substantially all of its net
assets in municipal obligations that provide income exempt from federal, New

could default

*   New York's economy and revenues underlying its municipal obligations
may decline

*   the fund's portfolio securities may be more sensitive to risks that are
specific to investing primarily in a single state

The fund is non-diversified, which means that a relatively high percentage of
the fund's assets may be invested in a limited number of issuers. Therefore, its
performance may be more vulnerable to changes in the market value of a single
issuer or a group of issuers.

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Participant share class performance from
year to year. The second table averages the fund's performance over time. Both
tables assume reinvestment of dividends. Of course, past performance is no
guarantee of future results.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

</TABLE>


This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Participant shares, and to compensate Dreyfus for advertising and
marketing Participant shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of this fee to institutions
which have purchased Participant shares for the benefit of others. Because this
fee is paid out of the fund's assets on an ongoing basis, over time it will
increase the cost of your investment and may cost you more than is payable with
other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement at any time upon at least 90
days' prior notice to investors, but has committed not to do so at least through
May 31, 2000.


Dreyfus New York Municipal Cash Management

<PAGE 19>

MANAGEMENT

The investment adviser for each fund is The Dreyfus Corporation, 200 Park
Avenue, New York, New York 10166. Founded in 1947, Dreyfus manages more than
$120 billion in over 160 mutual fund portfolios. For the past fiscal year, each
fund paid Dreyfus a management fee at the annual rate of 0.20% of the fund's
average daily net assets. Dreyfus is the primary mutual fund business of Mellon
Bank Corporation, a broad-based financial services company with a bank at its
core. With more than $389 billion of assets under management and $1.9 trillion
of assets under administration and custody, Mellon provides a full range of
banking, investment and trust products and services to individuals, businesses
and institutions. Mellon is headquartered in Pittsburgh, Pennsylvania.

The Dreyfus asset management philosophy is based on the belief that discipline
and consistency are important to investment success. For each fund, Dreyfus
seeks to establish clear guidelines for portfolio management and to be
systematic in making decisions. This approach is designed to provide each fund
with a distinct, stable identity.

Dreyfus has a personal securities trading policy (the "Policy") which restricts
the personal securities transactions of its employees. Its primary purpose is to
ensure that personal trading by Dreyfus employees does not disadvantage any
Dreyfus-managed fund. Dreyfus portfolio managers and other investment personnel
who comply with the Policy's preclearance and disclosure procedures may be
permitted to purchase, sell or hold certain types of securities which also may
be or are held in the fund(s) they advise.

Concepts to understand

YEAR 2000 ISSUES: these funds could be adversely affected if the computer
systems used by Dreyfus and the funds' other service providers do not properly
process and calculate date-related information from and after January 1, 2000.

Dreyfus is working to avoid year 2000-related problems in its systems and to
obtain assurances from other service providers that they are taking similar
steps. In addition, issuers of securities in which these funds invest may be
adversely affected by year 2000-related problems. This could have an impact on
the value of a fund's investments and its share price.

FINANCIAL HIGHLIGHTS

The following tables describe the performance of each fund's Participant shares
for the fiscal periods indicated. "Total return" shows how much your investment
in the fund would have increased (or decreased) during each period, assuming you
had reinvested all dividends and distributions. These figures have been
independently audited by Ernst & Young LLP, whose report, along with the fund's
financial statements, is included in the annual report.

Account Information

ACCOUNT POLICIES

EACH FUND IS DESIGNED for institutional investors, particularly banks, acting
for themselves or in a fiduciary, advisory, agency, custodial or similar
capacity. Fund shares may not be purchased directly by individuals, although
institutions may purchase shares for accounts maintained by individuals.
Generally, each investor will be required to open a single master account with
the fund for all purposes. In certain cases, the fund may request investors to
maintain separate master accounts for shares held by the investor (i) for its
own account, for the account of other institutions and for accounts for which
the institution acts as a fiduciary, and (ii) for accounts for which the
investor acts in some other capacity. An institution may arrange with the fund's
transfer agent for sub-accounting services and will be charged directly for the
cost of such services. Institutions purchasing Participant shares for the
benefit of their clients may impose policies, limitations and fees which are
different from those described in this prospectus.

Buying shares

THE PRICE FOR FUND SHARES is the fund's net asset value (NAV), which is
generally calculated twice a day, at 5 p.m. and 8 p.m. for the taxable money
market funds, and 12 noon and 8 p.m. for the municipal money market funds, every
day the New York Stock Exchange, or the transfer agent (as on Good Friday) as to
Dreyfus Cash Management and Dreyfus Cash Management Plus only, is open. An order
will be priced at the next NAV calculated after the order is accepted by the
fund's transfer agent or other authorized entity. Each fund's investments are
valued based on amortized cost. As a result, portfolio securities are valued at
their acquisition cost, adjusted for discounts or premiums reflected in their
purchase price. This method of valuation is designed for the fund to be able to
price its shares at $1.00 per share.

As to Dreyfus Cash Management, Dreyfus Cash Management Plus, Dreyfus Government
Cash Management and Dreyfus Treasury Cash Management, orders in proper form
placed prior to 5:00 p.m., and payments for which are received in or converted
into Federal Funds by the fund's custodian by 6:00 p.m., will become effective
at the price determined at 5:00 p.m. on that day. In this case, shares purchased
will receive the dividend declared on that day.

As to Dreyfus Government Prime Cash Management and Dreyfus Treasury Prime Cash
Management only, orders in proper form placed prior to 3:00 p.m., and payments
for which are received in or converted into Federal Funds by the fund's
custodian by 6:00 p.m., will become effective at the price determined at 5:00
p.m. on that day. In this case, shares purchased will receive the dividend
declared on that day. Orders for shares placed between 3:00 p.m and 5:00 p.m.
will not be accepted and executed, and notice of the purchase order being
rejected will be given to the institution placing the order, and any funds
received will be returned promptly to the sending institution.

Orders effected through compatible computer facilities after 5:00 p.m., but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders in proper form effected between 5:00 p.m. and 8:00 p.m., by a means other
than a compatible computer facility, will become effective on the following
business day.

All times are Eastern time.




<PAGE 26>

As to each municipal money market fund, investors whose orders in proper form
are placed and payments for which are received in or converted into Federal
Funds by the fund's custodian, prior to 12:00 noon, will be effective at the
price determined at 12:00 noon on that day. In this case, shares purchased will
receive the dividend declared on that day.

Orders effected through a compatible computer facility after 12:00 noon, but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders effected in proper form between 12:00 noon and 8:00 p.m., by a means

*The minimum initial investment in Participant shares is $10,000,000, unless:
(a) the investor has invested at least $10,000,000 in the aggregate among any
Dreyfus Cash Management fund and Dreyfus Institutional Short Term Treasury Fund
(including in any class of a fund); or (b) the investor has, in the opinion of
Dreyfus Institutional Services Division, adequate intent and availability of
assets to reach a future level of investment of $10,000,000 among the funds
named above.

Selling shares

INVESTORS MAY SELL (REDEEM) SHARES AT ANY TIME, by wire, telephone or compatible
computer facility. Shares will be sold at the next NAV calculated after an
investor's order is accepted by the fund's transfer agent or other authorized
entity. Any certificates representing fund shares being sold must be returned
with the redemption request. Orders will be processed promptly and investors
generally will receive the proceeds within a week.

BEFORE SELLING RECENTLY PURCHASED SHARES, please note that if the fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to eight business days or until it has collected payment.

General policies

UNLESS THE INVESTOR DECLINES TELEPHONE PRIVILEGES on the application, the
investor may be responsible for any fraudulent telephone order as long as
Dreyfus takes reasonable measures to verify the order.

EACH FUND RESERVES THE RIGHT TO:

*   refuse any purchase or exchange request that could adversely affect the
fund or its operations

*   change or discontinue its exchange privilege, or temporarily suspend
this privilege during unusual market conditions

*   change its minimum investment amounts

*   delay sending out redemption proceeds for up to seven days (generally
applies only in cases of very large redemptions, excessive trading or during
unusual market conditions)

Each fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount being redeemed is deemed
by the manager to be large enough to affect fund operations.

Account Information



<PAGE 27>

DISTRIBUTIONS AND TAXES

EACH FUND USUALLY PAYS ITS SHAREHOLDERS dividends from its net investment income
once a month, and distributes any net realized securities gains once a year.
Dividends and distributions will be reinvested in the fund unless the investor
instructs the fund otherwise. There are no fees or sales charges on
reinvestments.

DIVIDENDS AND DISTRIBUTIONS PAID by the taxable money market funds are taxable
to U.S. shareholders as ordinary income (unless the investment is in a
tax-advantaged account).

EACH MUNICIPAL MONEY MARKET FUND anticipates that, under normal market
conditions, virtually all of its income dividends will be exempt from federal
and, as to Dreyfus New York Municipal Cash Management, New York state and New
York city, personal income taxes. However, any dividends and distributions from
taxable investments are taxable as ordinary income.

The tax status of any distribution is the same regardless of how long the
investor has been in the fund and whether the investor reinvests distributions
or take them in cash.

Because each investor's tax situation is unique, the investor should consult a
professional about federal, state and local tax consequences.

Concepts to understand

DIVIDENDS: income or interest paid by the investments in a fund's portfolio, net
of expenses, passed on to fund shareholders.

DISTRIBUTIONS: income, net of expenses, passed on to fund shareholders. These
are calculated on a per-share basis: each share earns the same rate of return,
so the more fund shares you own, the higher your distribution.

SERVICES FOR FUND INVESTORS

Exchange privilege

AN INVESTOR MAY PURCHASE, in exchange for Participant shares of any Dreyfus Cash
Management fund, Participant shares of any other Dreyfus Cash Management fund,

monthly, semi-monthly, quarterly or annual basis), in exchange for Participant
Shares of any Dreyfus Cash Management fund, in Participant Shares of any other

MORE INFORMATION ON EACH FUND CAN BE FOUND IN THE FUND'S CURRENT
ANNUAL/SEMIANNUAL REPORT. SEE BACK COVER.

Introduction

Each fund is a money market mutual fund with a separate investment portfolio.
The operations and results of a fund are unrelated to those of each other fund.
This combined prospectus has been prepared for your convenience so that you can
consider three investment choices in one document.

As a money market fund, each fund is subject to maturity, quality and
diversification requirements designed to help it maintain a stable share price.

Dreyfus Cash Management Plus is required to invest at least 95% of its assets in
the securities of issuers with the highest credit rating or the unrated
equivalent as determined by Dreyfus, with the remainder invested in securities
with the second-highest credit rating. However, the fund purchases securities
with the highest credit rating only, or the unrated equivalent. Dreyfus
Government Prime Cash Management and Dreyfus Treasury Prime Cash Management
invest in U.S. government securities only.

An investment in a fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although each fund seeks
to preserve the value of your investment at $1.00 per share, it is possible to
lose money by investing in a fund.

Concepts to understand

MONEY MARKET FUND: a specific type of fund that seeks to maintain a $1.00 price
per share. Money market funds are subject to strict federal requirements and
must:

*  maintain an average dollar-weighted portfolio maturity of 90 days or
less

*  buy individual securities that have remaining maturities of 13 months or
less

*  invest only in high quality, dollar-denominated obligations

CREDIT RATING: a measure of the issuer's expected ability to make all required
interest and principal payments in a timely manner. An issuer with the highest
credit rating has a very strong degree of certainty (or safety) with respect to
making all payments. An issuer with the second-highest credit rating has a
strong capacity to make all payments, but the degree of safety is somewhat
less.

The Funds

<PAGE 1>


Dreyfus Cash Management Plus

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity. To pursue this goal,
the fund invests in a diversified portfolio of high quality, short-term debt
securities, including:

*   securities issued or guaranteed by the U.S. government or its agencies
   or instrumentalities

*   certificates of deposit, time deposits, bankers' acceptances and other
   short-term securities issued by domestic banks or foreign banks (or thrifts)
   or their subsidiaries or branches

*   repurchase agreements, including tri-party repurchase agreements

*   asset-backed securities

*   domestic and dollar-denominated foreign commercial paper, and other
   short-term corporate obligations, including those with floating or variable
   rates of interest

*   dollar-denominated obligations issued or guaranteed by one or more
   foreign governments or any of their political subdivisions or agencies

Normally, the fund invests at least 25% of its net assets in bank obligations.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in the portfolio mature and the proceeds are
reinvested in securities with different interest rates.

While the fund has maintained a constant share price since inception, and will
continue to try to do so, the following factors could reduce the fund's income
level and/or share price:

*   interest rates could rise sharply, causing the fund's share price to
drop

*   any of the fund's holdings could have its credit rating downgraded or
could default

*   the risks generally associated with concentrating investments in the
banking industry, such as interest rate risk, credit risk and regulatory
developments relating to the banking industry

*   the risks generally associated with dollar-denominated foreign
investments, such as economic and political developments, seizure or
nationalization of deposits, imposition of taxes or other restrictions on the
payment of principal and interest

If the other party entering into a repurchase agreement with the fund defaults
or becomes insolvent, the fund may be unable to sell the securities underlying
the repurchase agreement on a timely basis. In a tri-party repurchase agreement,
these securities are subject to a greater risk in a change in their value
because they may have a maturity of more than one year.


<PAGE 2>

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Participant share class performance from
year to year. The second table averages the fund's performance over time. Both
tables assume reinvestment of dividends. Of course, past performance is no
guarantee of future results.

The 7-day yield for Participant shares on 12/31/98 was 4.63%. Institutions may
call toll-free 1-800-346-3621 for the current yield for Participant shares.
Individuals or entities for whom institutions may purchase or redeem shares
should call the institution directly.

                                                             inception

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.

EXPENSES

As an investor, you pay certain fees and expenses in connection with the fund,
which are described in the table below. Annual fund operating expenses are paid
out of fund assets, so their effect is included in the share price.

</TABLE>


This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Participant shares, and to compensate Dreyfus for advertising and
marketing Participant shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of this fee to institutions
which have purchased Participant shares for the benefit of others. Because this
fee is paid out of the fund's assets on an ongoing basis, over time it will
increase the cost of your investment and may cost you more than is payable with
other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement at any time upon at least 90
days' prior notice to investors, but has committed not to do so at least through
May 31, 2000.


Dreyfus Cash Management Plus


<PAGE 3>

Dreyfus Government Prime Cash Management

GOAL/APPROACH

The fund seeks as high a level of current income as is consistent with the
preservation of capital and the maintenance of liquidity.

To pursue this goal, the fund only invests in securities issued or guaranteed as
to principal and interest by the U.S. government or its agencies or
instrumentalities.

MAIN RISKS

The fund's yield will fluctuate, as market and interest rate conditions change,
and as the short-term securities in its portfolio mature and the proceeds are
reinvested in securities with different interest rates.

A security backed by the U.S. Treasury or the full faith and credit of the
United States is guaranteed only as to the timely payment of interest and
principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

Certain U.S. government agency securities are backed by the right of the issuer
to borrow from the U.S. Treasury, or are supported only by the credit of the
issuer or instrumentality. While the U.S. government provides financial support
to U.S. government-sponsored agencies or instrumentalities, no assurance can be
given that it will always do so.

please refer to the Statement of Additional Information (SAI).

principal when held to maturity. The market prices for such securities are not
guaranteed and will fluctuate. The fund is subject to the risk that interest
rates could rise sharply, causing the fund's share price to drop.

PAST PERFORMANCE

The tables below show some of the risks of investing in the fund. The first
table shows the changes in the fund's Participant share class performance from
year to year. The second table averages the fund's performance over time. Both
tables assume reinvestment of dividends. Of course, past performance is no
guarantee of future results.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed
and gives you the opportunity to participate in financial markets. It strives to
reach its stated goal, although as with all mutual funds, it cannot offer
guaranteed results.

An investment in this fund is not a bank deposit. It is not insured or
guaranteed by the FDIC or any other government agency. It is not a complete
investment program. You could lose money in this fund, but you also have the
potential to make money.


EXPENSES

As an investor, you pay certain fees and expenses in connection the fund, which
are described in the table below. Annual fund operating expenses are paid out of
fund assets, so their effect is included in the share price.

</TABLE>


This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether you sold your shares at the end of a period or
kept them. Because actual return and expenses will be different, the example is
for comparison only.

Concepts to understand

MANAGEMENT FEE: the fee paid to the investment adviser for managing the fund's
portfolio and assisting in all aspects of the fund's operations.

RULE 12B-1 FEE: the fee paid to reimburse the fund's distributor for
distributing Participant shares, and to compensate Dreyfus for advertising and
marketing Participant shares, and for providing account service and maintenance.
Dreyfus and the distributor may pay all or part of this fee to institutions
which have purchased Participant shares for the benefit of others. Because this
fee is paid out of the fund's assets on an ongoing basis, over time it will
increase the cost of your investment and may cost you more than is payable with
other types of sales charges.


OTHER EXPENSES: under an agreement with Dreyfus, the fund only pays the
management fee and the Rule 12b-1 fee. Dreyfus pays all other fund expenses
directly. Dreyfus may terminate this agreement at any time upon at least 90
days' prior notice to investors, but has committed not to do so at least through
May 31, 2000.

Dreyfus Treasury Prime Cash Management

MANAGEMENT

The investment adviser for each fund is The Dreyfus Corporation, 200 Park
Avenue, New York, New York 10166. Founded in 1947, Dreyfus manages more than
$120 billion in over 160 mutual fund portfolios. For the past fiscal year, each
fund paid Dreyfus a management fee at the annual rate of 0.20% of the fund's
average daily net assets. Dreyfus is the primary mutual fund business of Mellon
Bank Corporation, a broad-based financial services company with a bank at its
core. With more than $389 billion of assets under management and $1.9 trillion
of assets under administration and custody, Mellon provides a full range of
banking, investment and trust products and services to individuals, businesses
and institutions. Mellon is headquartered in Pittsburgh, Pennsylvania.

The Dreyfus asset management philosophy is based on the belief that discipline
and consistency are important to investment success. For each fund, Dreyfus
seeks to establish clear guidelines for portfolio management and to be
systematic in making decisions. This approach is designed to provide each fund
with a distinct, stable identity.

Dreyfus has a personal securities trading policy (the "Policy") which restricts
the personal securities transactions of its employees. Its primary purpose is to
ensure that personal trading by Dreyfus employees does not disadvantage any
Dreyfus-managed fund. Dreyfus portfolio managers and other investment personnel
who comply with the Policy's preclearance and disclosure procedures may be
permitted to purchase, sell or hold certain types of securities which also may
be or are held in the fund(s) they advise.

Concepts to understand

YEAR 2000 ISSUES: these funds could be adversely affected if the computer
systems used by Dreyfus and the funds' other service providers do not properly
process and calculate date-related information from and after January 1, 2000.

Dreyfus is working to avoid year 2000-related problems in its systems and to
obtain assurances from other service providers that they are taking similar
steps. In addition, issuers of securities in which these funds invest may be
adversely affected by year 2000-related problems. This could have an impact on
the value of a fund's investments and its share price.

FINANCIAL HIGHLIGHTS

The following tables describe the performance of each fund's Participant shares
for the fiscal periods indicated. "Total return" shows how much your investment
in the fund would have increased (or decreased) during each period, assuming you
had reinvested all dividends and distributions. These figures have been
independently audited by Ernst & Young LLP, whose report, along with the fund's
financial statements, is included in the annual report.

Account Information

ACCOUNT POLICIES

EACH FUND IS DESIGNED for institutional investors, particularly banks, acting
for themselves or in a fiduciary, advisory, agency, custodial or similar
capacity. Fund shares may not be purchased directly by individuals, although
institutions may purchase shares for accounts maintained by individuals.
Generally, each investor will be required to open a single master account with
the fund for all purposes. In certain cases, the fund may request investors to
maintain separate master accounts for shares held by the investor (i) for its
own account, for the account of other institutions and for accounts for which
the institution acts as a fiduciary, and (ii) for accounts for which the
investor acts in some other capacity. An institution may arrange with the fund's
transfer agent for sub-accounting services and will be charged directly for the
cost of such services. Institutions purchasing Participant shares for the
benefit of their clients may impose policies, limitations and fees which are
different from those described in this prospectus.

Buying shares

THE PRICE FOR FUND SHARES is the fund's net asset value (NAV), which is
generally calculated twice a day, at 5 p.m. and 8 p.m., every day the New York
Stock Exchange, or the fund's transfer agent (as on Good Friday) as to Dreyfus
Cash Management Plus only, is open. An order will be priced at the next NAV
calculated after the order is accepted by the fund's transfer agent or other
authorized entity. Each fund's investments are valued based on amortized cost.
As a result, portfolio securities are valued at their acquisition cost, adjusted
for discounts or premiums reflected in their purchase price. This method of
valuation is designed for the fund to be able to price its shares at $1.00 per
share.

As to Dreyfus Cash Management Plus, orders in proper form placed prior to 5:00
p.m., and payments for which are received in or converted into Federal Funds by
the fund's custodian by 6:00 p.m., will become effective at the price determined
at 5:00 p.m. on that day. In this case, shares purchased will receive the
dividend declared on that day.

As to Dreyfus Government Prime Cash Management and Dreyfus Treasury Prime Cash
Management only, orders in proper form placed prior to 3:00 p.m., and payments
for which are received in or converted into Federal Funds by the fund's
custodian by 6:00 p.m., will become effective at the price determined at 5:00
p.m. on that day. In this case, shares purchased will receive the dividend
declared on that day. Orders for shares placed between 3:00 p.m and 5:00 p.m.
will not be accepted and executed, and notice of the purchase order being
rejected will be given to the institution placing the order, and any funds
received will be returned promptly to the sending institution.

Orders effected through compatible computer facilities after 5:00 p.m., but
prior to 8:00 p.m., will become effective at the price determined at 8:00 p.m.
on that day, if Federal Funds are received by the fund's custodian by 11:00 a.m.
on the following business day. In this case, shares purchased will start earning
dividends on the business day following the date the order became effective.
Orders in proper form effected between 5:00 p.m. and 8:00 p.m., by a means other
than a compatible computer facility, will become effective on the following
business day.

All times are Eastern time.

*The minimum initial investment in Participant shares is $10,000,000, unless:
(a) the investor has invested at least $10,000,000 in the aggregate among any
Dreyfus Cash Management fund and Dreyfus Institutional Short Term Treasury Fund
(including in any class of a fund); or (b) the investor has, in the opinion of
Dreyfus Institutional Services Division, adequate intent and availability of
assets to reach a future level of investment of $10,000,000 among the funds
named above.

Account Information


<PAGE 11>

ACCOUNT POLICIES (CONTINUED)

Selling shares

INVESTORS MAY SELL (REDEEM) SHARES AT ANY TIME, by wire, telephone or compatible
computer facility. Shares will be sold at the next NAV calculated after an
investor's order is accepted by the fund's transfer agent or other authorized
entity. Any certificates representing fund shares being sold must be returned
with the redemption request. Orders will be processed promptly and investors
generally will receive the proceeds within a week.

BEFORE SELLING RECENTLY PURCHASED SHARES, please note that if the fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to eight business days or until it has collected payment.


General policies

UNLESS THE INVESTOR DECLINES TELEPHONE PRIVILEGES on the application, the
investor may be responsible for any fraudulent telephone order as long as
Dreyfus takes reasonable measures to verify the order.

EACH FUND RESERVES THE RIGHT TO:

*   refuse any purchase or exchange request that could adversely affect the
fund or its operations

*   change or discontinue its exchange privilege, or temporarily suspend
this privilege during unusual market conditions

*   change its minimum investment amounts

*   delay sending out redemption proceeds for up to seven days (generally
applies only in cases of very large redemptions, excessive trading or during
unusual market conditions)

Each fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount being redeemed is deemed
by the manager to be large enough to affect fund operations.


<PAGE 12>


DISTRIBUTIONS AND TAXES

EACH FUND USUALLY PAYS ITS SHAREHOLDERS dividends from its net investment income
once a month, and distributes any net realized securities gains once a year.
Dividends and distributions will be reinvested in the fund unless the investor
instructs the fund otherwise. There are no fees or sales charges on
reinvestments.

DIVIDENDS AND DISTRIBUTIONS PAID by the funds are taxable to U.S. shareholders
as ordinary income (unless the investment is in a tax-advantaged account). The
tax status of any distribution is the same regardless of how long the investor
has been in the fund and whether the investor reinvests distributions or take
them in cash.

Because each investor's tax situation is unique, the investor should consult a
professional about federal, state and local tax consequences.

Concepts to understand

DIVIDENDS: income or interest paid by the investments in a fund's portfolio, net
of expenses, passed on to fund shareholders.

DISTRIBUTIONS: income, net of expenses, passed on to fund shareholders. These
are calculated on a per-share basis: each share earns the same rate of return,
so the more fund shares you own, the higher your distribution.

                          DESCRIPTION OF THE FUNDS

     Dreyfus Cash Management, the Company and Dreyfus Tax Exempt Cash
Management were formed originally as Maryland corporations on December 6,
1984, February 1, 1984, and January 27, 1984, respectively, and commenced
operations in March 1985.  On May 22, 1987, each of these Funds reorganized
as a Massachusetts business trust.

     Dreyfus Cash Management Plus is a Maryland corporation formed on
August 12, 1987.

     Dreyfus New York Municipal Cash Management, Dreyfus Municipal Cash
Management Plus, Dreyfus Treasury Cash Management, and Dreyfus Treasury
Prime Cash Management are Massachusetts business trusts that commenced
operations on November 4, 1991, October 15, 1990, September 4, 1986, and
December 27, 1988, respectively.

     Each Fund is an open-end management investment company, known as a
money market mutual fund.  Each Fund, other than Dreyfus New York Municipal
Cash Management, is a diversified fund, which means that, with respect to
75% of its total assets, the Fund will not invest more than 5% of its assets
in the securities of any single issuer.  Dreyfus New York Municipal Cash
Management is a non-diversified fund, which means that the proportion of the
Fund's assets that may be invested in the securities of a single issuer is
not limited by the Investment Company Act of 1940, as amended (the "1940
Act").

     The Dreyfus Corporation (the "Manager") serves as each Fund's
investment adviser.

     Premier Mutual Fund Services, Inc. (the "Distributor") is the
distributor of each Fund's shares.

Certain Portfolio Securities

     The following information supplements and should be read in conjunction
with the Funds' Prospectus.

     U.S. Treasury Securities. (Dreyfus Cash Management, Dreyfus Cash
Management Plus, Dreyfus Government Cash Management, Dreyfus Government
Prime Cash Management, Dreyfus Treasury Cash Management, and Dreyfus
Treasury Prime Cash Management (collectively, the "Taxable Funds"))  Each
Taxable Fund may invest in U.S. Treasury securities which include Treasury
Bills, Treasury Notes and Treasury Bonds that differ in their interest
rates, maturities and times of issuance.  Treasury Bills have initial
maturities of one year or less;  Treasury Notes have initial maturities of
one to ten years; and Treasury Bonds generally have initial maturities of
greater than ten years.

     U.S. Government Securities.  (Dreyfus Cash Management, Dreyfus Cash
Management Plus, Dreyfus Government Cash Management, and Dreyfus Government
Prime Cash Management).  Each of these Funds, in addition to U.S. Treasury
Securities, may invest in securities issued or guaranteed by the U.S.
Government or its agencies or instrumentalities.  Some obligations issued or
guaranteed by U.S. Government agencies and instrumentalities are supported
by the full faith and credit of the U.S. Treasury; others by the right of
the issuer to borrow from the U.S. Treasury; others by discretionary
authority of the U.S. Government to purchase certain obligations of the
agency or instrumentality; and others only by the credit of the agency or
instrumentality.  These securities bear fixed, floating or variable rates of
interest.  Interest may fluctuate based on generally recognized reference
rates or the relationship of rates.  While the U.S. Government currently
provides financial support to such U.S. Government-sponsored agencies or
instrumentalities, no assurance can be given that it will always do so,
since it is not so obligated by law.

     Bank Obligations.  (Dreyfus Cash Management and Dreyfus Cash Management
Plus)  Each of these Funds may purchase certificates of deposit ("CDs"),
time deposits ("TDs"), bankers' acceptances and other short-term obligations
issued by domestic banks, foreign subsidiaries or foreign branches of
domestic banks, domestic and foreign branches of foreign banks, domestic
savings and loan associations and other banking institutions.

     CDs are negotiable certificates evidencing the obligation of a bank to
repay funds deposited with it for a specified period of time.

     TDs are non-negotiable deposits maintained in a banking institution for
a specified period of time (in no event longer than seven days) at a stated
interest rate.

     Bankers' acceptances are credit instruments evidencing the obligation
of a bank to pay a draft drawn on it by a customer.  These instruments
reflect the obligation both of the bank and the drawer to pay the face
amount of the instrument upon maturity.  The other short-term obligations
may include uninsured, direct obligations bearing fixed, floating or
variable interest rates.

     Each of these Funds may invest in TDs and CDs issued by domestic banks
having total assets in excess of $1 billion or by London branches of such
domestic banks, and with respect to Dreyfus Cash Management Plus only,
foreign subsidiaries or foreign branches of domestic banks, and domestic and
foreign branches of foreign banks.  Each Fund also is authorized to purchase
CDs issued by banks, savings and loan associations and similar institutions
with less than $1 billion in assets, the deposits of which are insured by
the Federal Deposit Insurance Corporation ("FDIC"), provided the Fund
purchases any such CD in a principal amount of no more than $100,000, which
amount would be fully insured by the Bank Insurance Fund or the Savings
Association Insurance Fund administered by the FDIC.  Interest payments on
such a CD are not insured by the FDIC.  The Fund would not own more than one
such CD per such issuer.

     Domestic commercial banks organized under Federal law are supervised
and examined by the Comptroller of the Currency and are required to be
members of the Federal Reserve System and to have their deposits insured by
the FDIC.  Domestic banks organized under state law are supervised and
examined by state banking authorities but are members of the Federal Reserve
System only if they elect to join.  In addition, state banks whose CDs may
be purchased by the Fund are insured by the FDIC (although such insurance
may not be of material benefit to the Fund, depending on the principal
amount of the CDs of each bank held by the Fund) and are subject to Federal
examination and to a substantial body of Federal law and regulation.  As a
result of Federal and state laws and regulations, domestic branches of
domestic banks whose CDs may be purchased by the Fund generally, among other
things, are required to maintain specified levels of reserves and are
subject to other supervision and regulation designed to promote financial
soundness.  However, not all of such laws and regulations apply to the
foreign branches of domestic banks.

     CDs held by the Fund, other than those issued by banks with less than
$1 billion in assets as described above, do not benefit materially, and time
deposits do not benefit at all, from insurance from the Bank Insurance Fund
or the Savings Association Insurance Fund administered by the FDIC.

     Obligations of foreign branches and foreign subsidiaries of domestic
banks, and domestic and foreign branches of foreign banks may be general
obligations of the parent banks in addition to the issuing branch, or may be
limited by the terms of a specific obligation and governmental regulation.
Such obligations are subject to different risks than are those of domestic
banks.  These risks include foreign economic and political developments,
foreign governmental restrictions that may adversely affect payment of
principal and interest on the obligations, foreign exchange controls and
foreign withholding and other taxes on interest income.  Foreign branches
and subsidiaries are not necessarily subject to the same or similar
regulatory requirements that apply to domestic banks, such as mandatory
reserve requirements, loan limitations, and accounting, auditing and
financial recordkeeping requirements.  In addition, less information may be
publicly available about a foreign branch of a domestic bank or about a
foreign bank than about a domestic bank.

     Obligations of United States branches of foreign banks may be general
obligations of the parent bank in addition to the issuing branch, or may be
limited by the terms of a specific obligation or by Federal or state
regulation as well as governmental action in the country in which the
foreign bank has its head office.  A domestic branch of a foreign bank with
assets in excess of $1 billion may or may not be subject to reserve
requirements imposed by the Federal Reserve System or by the state in which
the branch is located if the branch is licensed in that state.

     In addition, Federal branches licensed by the Comptroller of the
Currency and branches licensed by certain states ("State Branches") may be
required to: (1) pledge to the regulator, by depositing assets with a
designated bank within the state, a certain percentage of their assets as
fixed from time to time by the appropriate regulatory authority; and (2)
maintain assets within the state in an amount equal to a specified
percentage of the aggregate amount of liabilities of the foreign bank
payable at or through all of its agencies or branches within the state.  The
deposits of Federal and State Branches generally must be insured by the FDIC
if such branches take deposits of less than $100,000.

     In view of the foregoing factors associated with the purchase of CDs
and TDs issued by foreign branches or foreign subsidiaries of domestic
banks, or by foreign branches or  domestic branches of foreign banks, the
Manager carefully evaluates such investments on a case-by-case basis.

     Commercial Paper.  (Dreyfus Cash Management and Dreyfus Cash Management
Plus) Each of these Funds may purchase commercial paper consisting of short-
term, unsecured promissory notes issued to finance short-term credit needs.
The commercial paper purchased by each Fund will consist only of direct
obligations.  The other corporate obligations in which each of these Funds
may invest consist of high quality, U.S. dollar denominated short-term bonds
and notes (including variable amount master demand notes).

     Floating and Variable Rate Obligations.  (Dreyfus Cash Management Plus)
Dreyfus Cash Management Plus may purchase floating and variable rate demand
notes and bonds, which are obligations ordinarily having stated maturities
in excess of 13 months, but which permit the holder to demand payment of
principal at any time, or at specified intervals not exceeding 13 months, in
each case upon not more than 30 days' notice.  Variable rate demand notes
include master demand notes which are obligations that permit the Fund to
invest fluctuating amounts, at varying rates of interest, pursuant to direct
arrangements between the Fund, as lender, and the borrower.  These
obligations permit daily changes in the amounts borrowed.  Because these
obligations are direct lending arrangements between the lender and borrower,
it is not contemplated that such instruments generally will be traded, and
there generally is no established secondary market for these obligations,
although they are redeemable at face value, plus accrued interest.
Accordingly, where these obligations are not secured by letters of credit or
other credit support arrangements, the Fund's right to redeem is dependent
on the ability of the borrower to pay principal and interest on demand.

     Asset-Backed Securities.  (Dreyfus Cash Management Plus)  Dreyfus Cash
Management Plus may purchase asset-backed securities, which are securities
issued by special purpose entities whose primary assets consist of a pool of
mortgages, loans, receivables or other assets.  Payment of principal and
interest may depend largely on the cash flows generated by the assets
backing the securities and, in certain cases, supported by letters of
credit, surety bonds or other forms of credit or liquidity enhancements.
The value of these asset-backed securities also may be affected by the
creditworthiness of the servicing agent for the pool of assets, the
originator of the loans or receivables or the financial institution
providing the credit support.


     Repurchase Agreements.  (Dreyfus Cash Management, Dreyfus Cash Management
Plus, Dreyfus Government Cash Management, and Dreyfus Treasury Cash Management)
Each of these Funds may enter into repurchase agreements.  In a repurchase
agreement, the Fund buys, and the seller agrees to  repurchase, a security at a
mutually agreed upon time and price (usually within seven days).  The repurchase
agreement thereby determines the yield during the purchaser's holding period,
while the seller's obligation to repurchase is secured by the value of the
underlying security.  The Fund's custodian or sub-custodian employed in
connection with tri- party repurchase agreement transactions will have custody
of, and will hold in a segregated account, securities acquired by such Fund
under a repurchase agreement.  In connection with its third-party repurchase
transactions, the Fund will employ only eligible sub-custodians that meet the
requirements set forth in section 17(f) of the 1940 Act.  Repurchase agreements
are considered  by the staff of the Securities and Exchange Commission to be
loans by the Fund. Repurchase agreements could involve risks in the event of a
default or insolvency of the other party to the agreement, including possible
delays or restrictions upon a Fund's ability to dispose of the underlying
securities.  In an attempt to reduce the risk of incurring a loss on a
repurchase agreement, the Fund will enter into repurchase agreements only with
domestic banks with total assets in excess of $1 billion, or primary government
securities dealers reporting to the Federal Reserve Bank of New York, with
respect to securities of the type in which such Fund may invest and, in the
case of tri-party repurchase agreements, U.S. Government securities with a
maturity of greater than one year, and will require that additional securities
be deposited with it if the value of the securities purchased should decrease
below resale price.


     Municipal Obligations.  (Dreyfus Municipal Cash Management Plus,
Dreyfus Tax Exempt Cash Management, and Dreyfus New York Municipal Cash
Management (collectively, the "Tax Exempt Funds"))  Each Tax Exempt Fund
will invest at least 80% of the value of its net assets (except when
maintaining a temporary defensive position) in Municipal Obligations.
Municipal Obligations are debt obligations issued by states, territories and
possessions of the United States and the District of Columbia and their
political subdivisions, agencies and instrumentalities, or multistate
agencies or authorities, the interest from which, in the opinion of bond
counsel to the issuer, is exempt from Federal income tax.  Municipal
Obligations generally include debt obligations issued to obtain funds for
various public purposes as well as certain industrial development bonds
issued by or on behalf of public authorities.  Municipal Obligations are
classified as general obligation bonds, revenue bonds and notes.  General
obligation bonds are secured by the issuer's pledge of its faith, credit and
taxing power for the payment of principal and interest.  Revenue bonds are
payable from the revenue derived from a particular facility or class of
facilities or, in some cases, from the proceeds of a special excise or other
specific revenue source, but not from the general taxing power.  Tax exempt
industrial development bonds, in most cases, are revenue bonds that do not
carry the pledge of the credit of the issuing municipality, but generally
are guaranteed by the corporate entity on whose behalf they are issued.
Notes are short-term instruments which are obligations of the issuing
municipalities or agencies and are sold in anticipation of a bond sale,
collection of taxes or receipt of other revenues.  Municipal Obligations
include municipal lease/purchase agreements which are similar to installment
purchase contracts for property or equipment issued by municipalities.
Municipal Obligations bear fixed, floating or variable rates of interest.
Certain Municipal Obligations are subject to redemption at a date earlier
than their stated maturity pursuant to call options, which may be separated
from the related Municipal Obligation and purchased and sold separately.

     For the purpose of diversification under the 1940 Act, the
identification of the issuer of Municipal Obligations depends on the terms
and conditions of the security. When the assets and revenues of an agency,
authority, instrumentality or other political subdivision are separate from
those of the government creating the subdivision and the security is backed
only by the assets and revenues of the subdivision, such subdivision would
be deemed to be the sole issuer.  Similarly, in the case of an industrial
development bond, if that bond is backed only by the assets and revenues of
the non-governmental user, then such non-governmental user would be deemed
to be the sole issuer.  If, however, in either case, the creating government
or some other entity guarantees a security, such a guaranty would be
considered a separate security and will be treated as an issue of such
government or other entity.

     The yields on Municipal Obligations are dependent on a variety of
factors, including general economic and monetary conditions, money market
factors, conditions in the Municipal Obligations market, size of a
particular offering, maturity of the obligation, and rating of the issue.

     Certain Tax Exempt Obligations.  (Tax Exempt Funds)  Each Tax Exempt
Fund may purchase floating and variable rate demand notes and bonds, which
are tax exempt obligations ordinarily having stated maturities in excess of
13 months, but which permit the holder to demand payment of principal at any
time or at specified intervals not exceeding 13 months, in each case upon
not more than 30 days' notice.  Variable rate demand notes include master
demand notes which are obligations that permit the Fund to invest
fluctuating amounts, at varying rates of interest, pursuant to direct
arrangements between the Fund, as lender, and the borrower.  These
obligations permit daily changes in the amount borrowed.  Frequently, such
obligations are secured by letters of credit or other credit support
arrangements provided by banks.  Changes in the credit quality of banks and
other financial institutions that provide such credit or liquidity
enhancements to the Fund's portfolio securities could cause losses to the
Fund and affect its share price.  Because these obligations are direct
lending arrangements between the lender and borrower, it is not contemplated
that such instruments generally will be traded, and there generally is no
established secondary market for these obligations, although they are
redeemable at face value, plus accrued interest.  Accordingly, where these
obligations are not secured by letters of credit or other credit support
arrangements, the Fund's right to redeem is dependent on the ability of the
borrower to pay principal and interest on demand.  Each obligation purchased
by the Fund will meet the quality criteria established for the purchase of
Municipal Obligations.

     Tax Exempt Participation Interests.  (Tax Exempt Funds)  Each Tax
Exempt Fund may purchase from financial institutions participation interests
in Municipal Obligations (such as industrial development bonds and municipal
lease/purchase agreements).  A participation interest gives the Fund an
undivided interest in the Municipal Obligation in the proportion that the
Fund's participation interest bears to the total principal amount of the
Municipal Obligation.  These instruments may have fixed, floating or
variable rates of interest, with remaining maturities of 13 months or less.
If the participation interest is unrated, it will be backed by an
irrevocable letter of credit or guarantee of a bank that the Fund's Board
has determined meets prescribed quality standards for banks, or the payment
obligation otherwise will be collateralized by U.S. Government securities.
For certain participation interests, the Fund will have the right to demand
payment, on not more than seven days' notice, for all or any part of the
Fund's participation interest in the Municipal Obligation, plus accrued
interest.  As to these instruments, the Fund intends to exercise its right
to demand payment only upon a default under the terms of the Municipal
Obligation, as needed to provide liquidity to meet redemptions, or to
maintain or improve the quality of its investment portfolio.

     Municipal lease obligations or installment purchase contract
obligations (collectively, "lease obligations") have special risks not
ordinarily associated with Municipal Obligations.  Although lease
obligations do not constitute general obligations of the municipality for
which the municipality's taxing power is pledged, a lease obligation
ordinarily is backed by the municipality's covenant to budget for,
appropriate and make the payments due under the lease obligation.  However,
certain lease obligations contain "non-appropriation" clauses which provide
that the municipality has no obligation to make lease or installment
purchase payments in future years unless money is appropriated for such
purpose on a yearly basis.  Although "non-appropriation" lease obligations
are secured by the leased property, disposition of the property in the event
of foreclosure might prove difficult.  The Fund will seek to minimize these
risks by investing only in those lease obligations that (1) are rated in one
of the two highest rating categories for debt obligations by at least two
nationally recognized statistical rating organizations (or one rating
organization if the lease obligation was rated only by one such
organization) or (2) if unrated, are purchased principally from the issuer
or domestic banks or other responsible third parties, in each case only if
the seller shall have entered into an agreement with the Fund providing that
the seller or other responsible third party will either remarket or
repurchase the lease obligation within a short period after demand by the
Fund.  The staff of the Securities and Exchange Commission currently
considers certain lease obligations to be illiquid.  Accordingly, not more
than 10% of the value of a Fund's net assets will be invested in lease
obligations that are illiquid and in other illiquid securities.

     Stand-By Commitments.  (Tax Exempt Funds) Each Tax Exempt Fund may
acquire "stand-by commitments" with respect to Municipal Obligations held in
its portfolio.  Under a stand-by commitment, the Fund obligates a broker,
dealer or bank to repurchase, at the Fund's option, specified securities at
a specified price and, in this respect, stand-by commitments are comparable
to put options.  The exercise of a stand-by commitment, therefore, is
subject to the ability of the seller to make payment on demand.  The Fund
will acquire stand-by commitments solely to facilitate its portfolio
liquidity and does not intend to exercise its rights thereunder for trading
purposes.  The Fund may pay for stand-by commitments if such action is
deemed necessary, thus increasing to a degree the cost of the underlying
Municipal Obligation and similarly decreasing such security's yield to
investors.  Gains realized in connection with stand-by commitments will be
taxable.

     Ratings of Municipal Obligations.  (Tax Exempt Funds)  Each Tax Exempt
Fund may invest only in those Municipal Obligations which are rated in one
of the two highest rating categories for debt obligations by at least two
rating organizations (or one rating organization if the instrument was rated
by only one such organization) or, if unrated, are of comparable quality as
determined in accordance with procedures established by the Fund's Board.

     The average distribution of investments (at value) in Municipal
Obligations (including notes) by ratings as of the fiscal year ended January
31, 1999, computed on a monthly basis, was as follows:

_______________________________

* Included in the Not Rated category are securities for Dreyfus Municipal
  Cash Management Plus, Dreyfus Tax Exempt Cash Management, and Dreyfus New
  York Municipal Cash Management, respectively, are securities which, while
  not rated, have been determined by the Manager to be of comparable
  quality to securities in the VMIG 1/MIG 1 or SP-1+/SP-1 rating
  categories.


     If, subsequent to its purchase by the Fund, (a) an issue of rated
Municipal Obligations ceases to be rated in the highest rating category by
at least two rating organizations (or one rating organization if the
instrument was rated by only one such organization) or the Fund's Board
determines that it is no longer of comparable quality or (b) the Manager
becomes aware that any portfolio security not so highly rated or any unrated
security has been given a rating by any rating organization below the rating
organization's second highest rating category, the Fund's Board will
reassess promptly whether such security presents minimal credit risk and
will cause the Fund to take such action as it determines is in the best
interest of the Fund and its shareholders; provided that the reassessment
required by clause (b) is not required if the portfolio security is disposed
of or matures within five business days of the Manager becoming aware of the
new rating and the Fund's Board is subsequently notified of the Manager's
actions.

     To the extent the ratings given by Moody's, S&P or Fitch change as a
result of changes in such organizations or their rating systems, each Fund
will attempt to use comparable ratings as standards for its investments in
accordance with the investment policies contained in the Funds' Combined
Prospectuses and this Statement of Additional Information.  The ratings of
Moody's, S&P and Fitch represent their opinions as to the quality of the
Municipal Obligations which they undertake to rate.  It should be
emphasized, however, that ratings are relative and subjective and are not
absolute standards of quality.  Although these ratings may be an initial
criterion for selection of portfolio investments, the Manager also will
evaluate these securities and the creditworthiness of the issuers of such
securities based upon financial and other available information.

     Taxable Investments.  (Tax Exempt Funds)  From time to time, on a
temporary basis other than for temporary defensive purposes (but not to
exceed 20% of the value of the Fund's net assets) or for temporary defensive
purposes, each Tax Exempt Fund may invest in taxable short-term investments
("Taxable Investments") consisting of:  notes of issuers having, at the time
of purchase, a quality rating within the two highest grades of Moody's, S&P
or Fitch; obligations of the U.S. Government, its agencies or
instrumentalities; commercial paper rated not lower than P-1 by Moody's, A-1
by S&P or F-1 by Fitch; CDs of U.S. domestic banks, including foreign
branches of domestic banks, with assets of $1 billion dollars or more; TDs;
bankers' acceptances and other short-term bank obligations; and repurchase
agreements in respect of any of the foregoing.  Dividends paid by the Fund
that are attributable to income earned by the Fund from Taxable Investments
will be taxable to investors.  Except for temporary defensive purposes, at
no time will more than 20% of the value of the Fund's net assets be invested
in Taxable Investments and, with respect to Dreyfus Tax Exempt Cash
Management, Municipal Obligations the interest from which gives rise to a
preference item for the purpose of the alternative minimum tax.  If the Fund
purchases Taxable Investments, it will value them using the amortized cost
method and comply with the provisions of Rule 2a-7 relating to purchases of
taxable instruments.  Under normal market conditions, none of the Funds
anticipate that more than 5% of the value of its total assets will be
invested in any one category of Taxable Investments.

     Illiquid Securities.  (All Funds)  Each Fund may invest up to 10% of
the value of its net assets in securities as to which a liquid trading
market does not exist, provided such investments are consistent with the
Fund's investment objective.  These securities may include securities that
are not readily marketable, such as securities that are subject to legal or
contractual restrictions on resale, and repurchase agreements providing for
settlement in more than seven days after notice.  As to these securities,
the Fund is subject to a risk that should the Fund desire to sell them when
a ready buyer is not available at a price the Fund deems representative of
their value, the value of the Fund's net assets could be adversely affected.

Investment Techniques

     In addition to the principal investment strategies discussed in the
Funds' Prospectus, each Fund also may engage in the investment techniques
described below.

     Borrowing Money.  (All Funds)  Each Fund may borrow money from banks
for temporary or emergency (not leveraging) purposes in an amount up to 15%
of the value of its total assets (including the amount borrowed) valued at
the lesser of cost or market, less liabilities (not including the amount
borrowed) at the time the borrowing is made.  While borrowings exceed 5% of
the value of a Fund's total assets, the Fund will not make any additional
investments.  In addition, Dreyfus Cash Management Plus may borrow for
investment purposes on a secured basis through entering into reverse
repurchase agreements as described below.


     Lending Portfolio Securities.  (Dreyfus Cash Management Plus)  Each of
these Funds may lend securities from its portfolio to brokers, dealers and
other financial institutions needing to borrow securities to complete
certain transactions.  The Fund continues to be entitled to payments in
amounts equal to the interest or other distributions payable on the loaned
securities which affords the Fund an opportunity to earn interest on the
amount of the loan and on the loaned securities' collateral.  Loans of
portfolio securities may not exceed 33-1/3% (20% as to Dreyfus Government
Cash Management) of the value of the Fund's total assets, and the Fund will
receive collateral consisting of cash or, as to Dreyfus Cash Management
Plus, cash equivalents, U.S. Government securities, or other high quality
liquid debt securities, or, as to Dreyfus Government Cash Management and
Dreyfus Government Prime Cash Management, U.S. Treasury securities, which
will be maintained at all times in an amount equal to at least 100% of the
current market value of the loaned securities.  Such Loans are terminable by
the Fund at any time upon specified notice.  The Fund might experience risk
of loss if the institution with which it has engaged in a portfolio loan
transaction breaches its agreement.  In connection with its securities
lending practices, the Fund may return to the borrower or a third party
which is unaffiliated with the Fund, and which is acting as a "placing
broker," a part of the interest earned from the investment of collateral
received for securities loaned.


     Reverse Repurchase Agreements.  (Dreyfus Cash Management Plus)  Dreyfus
Cash Management Plus may enter into reverse repurchase agreements with
banks, brokers or dealers.  Reverse purchase agreements involve the transfer
by the Fund of an underlying debt instrument in return for cash proceeds
based on a percentage of the value of the security.  The Fund retains the
right to receive interest and principal payments on the security.  The Fund
will use the proceeds of reverse repurchase agreements only to make
investments which generally either mature or have a demand feature to resell
to the issuer at a date simultaneous with or prior to the expiration of the
reverse repurchase agreement.  At an agreed upon future date, the Fund
repurchases the security, at principal, plus accrued interest.  As a result
of these transactions, the Fund is exposed to greater potential fluctuations
in the value of its assets and its net asset value per share.  These
borrowings will be subject to interest costs which may or may not be
recovered by appreciation of the securities purchased; in certain cases,
interest costs may exceed and return received on the securities purchased.
The Fund's Board has considered the risks to the Fund and its shareholders
which may result from the entry into reverse repurchase agreements and has
determined that the entry into such agreements is consistent with the Fund's
investment objective and management policies.  The Fund will segregate
permissible liquid assets equal to the aggregate amount of its reverse
repurchase obligations, plus accrued interest, in certain cases, in
accordance with releases promulgated by the Securities and Exchange
Commission.

     Forward Commitments.  (Dreyfus Cash Management Plus, Dreyfus Government
Cash Management, Dreyfus Government Prime Cash Management and each Tax
Exempt Fund)   Each of these Funds may purchase portfolio securities on a
forward commitment or when-issued basis, which means that delivery and
payment take place a number of days after the date of the commitment to
purchase.  The payment obligation and the interest rate receivable on a
forward commitment or when-issued security are fixed when the Fund enters
into the commitment, but the Fund does not make payment until it receives
delivery from the counterparty.  The Fund will commit to purchase such
securities only with the intention of actually acquiring the securities, but
the Fund may sell these securities before the settlement date if it is
deemed advisable.  The Fund will segregate permissible liquid assets at
least equal at all times to the amount of the purchase commitment.

     Securities purchased on a forward commitment or when-issued basis are
subject to changes in value (generally changing in the same way, i.e.,
appreciating when interest rates decline and depreciating when interest
rates rise) based upon the public's perception of the creditworthiness of
the issuer and changes, real or anticipated, in the level of interest rates.
Securities purchased on a when-issued basis may expose the Fund to risks
because they may experience such fluctuations prior to their actual
delivery.  Purchasing securities on a when-issued basis can involve the
additional risk that the yield available in the market when the delivery
takes place actually may be higher than that obtained in the transaction
itself.  Purchasing securities on a forward commitment or when-issued basis
when the Fund is fully or almost fully invested may result in greater
potential fluctuation in the value of the Fund's net assets and its net
asset value per share.

Investment Considerations and Risks

     Bank Securities.  (Dreyfus Cash Management and Dreyfus Cash Management
Plus)  To the extent each of these Funds' investments are concentrated in
the banking industry, the Fund will have correspondingly greater exposure to
the risk factors which are characteristic of such investments.  Sustained
increases in interest rates can adversely affect the availability or
liquidity and cost of capital funds for a bank's lending activities, and a
deterioration in general economic conditions could increase the exposure to
credit losses.  In addition, the value of and the investment return on the
Fund's shares could be affected by economic or regulatory developments in or
related to the banking industry, which industry also is subject to the
effects of competition within the banking industry as well as with other
types of financial institutions.  The Fund, however, will seek to minimize
its exposure to such risks by investing only in debt securities which are
determined to be of the highest quality.

     Foreign Securities.  (Dreyfus Cash Management and Dreyfus Cash
Management Plus)  Each of these Funds may invest in securities issued by
London branches of domestic banks, and Dreyfus Cash Management Plus may
invest in securities issued by foreign subsidiaries or foreign branches of
domestic banks, domestic and foreign branches of foreign banks, and
commercial paper issued by foreign issuers.  Accordingly, the Fund may be
subject to additional investment risks with respect to those securities that
are different in some respects from those incurred by a fund which invests
only in debt obligations of U.S. domestic issuers, although such obligations
may be higher yielding when compared to the securities of U.S. domestic
issuers.  Such risks include possible future political and economic
developments, seizure or nationalization of foreign deposits, imposition of
foreign withholding taxes on interest income payable on the securities,
establishment of exchange controls or adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and
interest on these securities.

     Investing in Municipal Obligations.  (Tax Exempt Funds)  Each Tax
Exempt Fund may invest more than 25% of the value of its total assets in
Municipal Obligations which are related in such a way that an economic,
business or political development or change affecting one such security also
would affect the other securities; for example, securities the interest upon
which is paid from revenues of similar types of projects.  As a result, the
Fund may be subject to greater risk as compared to a fund that does not
follow this practice.

     Certain municipal lease/purchase obligations in which each Tax Exempt
Fund may invest may contain "non-appropriation" clauses which provide that
the municipality has no obligation to make lease payments in future years
unless money is appropriated for such purpose on a yearly basis.  Although
"non-appropriation" lease/purchase obligations are secured by the leased
property, disposition of the leased property in the event of foreclosure
might prove difficult.  In evaluating the credit quality of a municipal
lease/purchase obligation that is unrated, the Manager will consider, on an
ongoing basis, a number of factors including the likelihood that the issuing
municipality will discontinue appropriating funding for the leased property.

     Certain provisions in the Internal Revenue Code of 1986, as amended
(the "Code"), relating to the issuance of Municipal Obligations may reduce
the volume of Municipal Obligations qualifying for Federal tax exemption.
One effect of these provisions could be to increase the cost of the
Municipal Obligations available for purchase by the Fund and thus reduce
available yield.  Shareholders should consult their tax advisers concerning
the effect of these provisions on an investment in the Fund.  Proposals that
may restrict or eliminate the income tax exemption for interest on Municipal
Obligations may be introduced in the future.  If any such proposal were
enacted that would reduce the availability of Municipal Obligations for
investment by the Fund so as to adversely affect Fund shareholders, the Fund
would reevaluate its investment objective and policies and submit possible
changes in the Fund's structure to shareholders for their consideration.  If
legislation were enacted that would treat a type of Municipal Obligation as
taxable, the Fund would treat such security as a permissible Taxable
Investment within the applicable limits set forth herein.

     Investing in New York Municipal Obligations.  (Dreyfus New York
Municipal Cash Management)  Each investor should consider carefully the
special risks inherent in investing in New York Municipal Obligations by the
Fund.  These risks result from the financial condition of New York State and
certain of its public bodies and municipalities, including New York City.
Beginning in early 1975, New York State, New York City and other State
entities faced serious financial difficulties which jeopardized the credit
standing and impaired the borrowing abilities of such entities and
contributed to high interest rates on, and lower market prices for, debt
obligations issued by them.  A recurrence of such financial difficulties or
a failure of certain financial recovery programs could result in defaults or
declines in the market values of various New York Municipal Obligations in
which the Fund may invest.  If there should be a default or other financial
crisis relating to New York State, New York City, a State or City agency, or
a State municipality, the market value and marketability of outstanding New
York Municipal Obligations in the Fund's portfolio and the interest income
to the Fund could be adversely affected.  Moreover, the national recession
and the significant slowdown in the New York and regional economies in the
early 1990s added substantial uncertainty to estimates of the State's tax
revenues, which, in part, caused the State to incur cash-basis operating
deficits in the General Fund and issue deficit notes during the fiscal
periods 1989 through 1992.  New York State's financial operations have
improved, however, during recent fiscal years.  For its fiscal years 1993
through 1998, the State recorded balanced budgets on a cash basis, with
positive fund balances in the General Fund.  New York State ended its 1997-
98 fiscal year on March 31, 1998 in balance on a cash basis, with a cash
surplus in the General Fund of approximately $2.04 billion.  There can be no
assurance that New York will not face substantial potential budget gaps in
future years.  Investors should review "Appendix C" which more fully sets
forth these and other risk factors.

     Simultaneous Investments.  (All Funds)  Investment decisions for each
Fund are made independently from those of other investment companies advised
by the Manager.  If, however, such other investment companies desire to
invest in, or dispose of, the same securities as the Fund, available
investments or opportunities for sales will be allocated equitably to each.
In some cases, this procedure may adversely affect the size of the position
obtained for or disposed of by the Fund or the price paid or received by the
Fund.

Investment Restrictions

     Each Fund's investment objective is a fundamental policy, which cannot
be changed without approval by the holders of a majority (as defined in the
1940 Act) of the Fund's outstanding voting shares.  In addition, the Funds
have adopted certain investment restrictions as fundamental policies and
certain other investment restrictions as non-fundamental policies, as

municipal bonds or industrial revenue bonds.

     2.   Borrow money, except from banks for temporary or emergency (not
leveraging) purposes in an amount up to 15% of the value of the Fund's total

                           MANAGEMENT ARRANGEMENTS

     Investment Adviser.  The Manager is a wholly-owned subsidiary of Mellon

incorporated under Pennsylvania law in 1971 and registered under the Federal
Bank Holding Company Act of 1956, as amended.  Mellon provides a
comprehensive range of financial products and services in domestic and
selected international markets.  Mellon is among the twenty-five largest
bank holding companies in the United States based on total assets.


     The Manager provides management services pursuant to separate
Management Agreements (respectively, the "Agreement") dated August 24, 1994
with each Fund.  As to each Fund, the Agreement is subject to annual
approval by (i) such Fund's Board or (ii) vote of a majority (as defined in
the 1940 Act) of such Fund's outstanding voting securities of the Fund,
provided that in either event the continuance also is approved by a majority
of the Fund's Board members who are not "interested persons" (as defined in
the 1940 Act) of the Fund or the Manager, by vote cast in person at a
meeting called for the purpose of voting on such approval. Each Agreement
was approved by Fund shareholders on August 5, 1994 (except as to Dreyfus
Government Prime Cash Management), and was last approved by each Fund's
Board, including a majority of the Board members who are not "interested
persons" of any party to the Agreement, at a meeting held on May 19, 1999.
With respect to Dreyfus Government Prime Cash Management, the Agreement was
approved by Fund shareholders on February 27, 1998, and was approved by the
Fund's Board at a meeting held on January 30, 1998.  As to each Fund, the
Agreement is terminable without penalty, on not more than 60 days' notice,
by the Fund's Board or by vote of the holders of a majority of such Fund's
shares, or, on not less than 90 days' notice, by the Manager.  Each
Agreement will terminate automatically in the event of its assignment (as
defined in the 1940 Act).

Board.  The Manager is responsible for investment decisions, and provides
each Fund with portfolio managers who are authorized by the Board to execute
purchases and sales of securities.  The portfolio managers of the Taxable

Riordan.  The portfolio managers of the Tax Exempt Funds are Joseph P.
Darcy, A. Paul Disdier, Douglas J. Gaylor, Karen M. Hand, Stephen C. Kris,

and Monica S. Wieboldt. The Manager also maintains a research department
with a professional staff of portfolio managers and securities analysts who

Manager.


     The Manager maintains office facilities on behalf of each Fund, and
furnishes statistical and research data, clerical help, accounting, data
processing, bookkeeping and internal auditing and certain other required
services to the Funds.  The Manager may pay the Distributor for shareholder
services from the Manager's own assets, including past profits but not
including the management fee paid by the Funds.  The Distributor may use
part or all of such payments to pay Service Agents (as defined below) in
respect of these services.  The Manager also may make such advertising and
promotional expenditures, using its own resources, as it from time to time
deems appropriate.

     As compensation for the Manager's services under the Agreement, each
Fund has agreed to pay the Manager a monthly management fee at the annual
rate of .20% of the value of such Fund's average daily net assets.  All fees
and expenses are accrued daily and deducted before declaration of dividends
to investors.  Set forth below are the total amounts paid by each Fund to

   Management each changed their fiscal year end from July 31 to January 31;
   Dreyfus Municipal Cash Management Plus changed its fiscal year end from
   December 31 to January 31; Dreyfus Treasury Prime Cash Management changed its
   fiscal year end from the last day of February to January 31; and Dreyfus Cash
   Management Plus changed its fiscal year end from September 30 to January 31.

** For the period from February 27, 1998 (commencement of investment operations)
   to January 31, 1999.

    As to each Fund, for the fiscal year ending January 31, 2000 and
thereafter, until the Manager gives the Fund's investors at least 90 days'
notice to the contrary, the Manager, and not the Fund, will be liable for
all expenses of the Fund (exclusive of taxes, brokerage, interest on
borrowings and (with the prior written consent of the necessary state
securities commissions) extraordinary expenses) other than the following
expenses, which will be borne by the Fund: (i) the management fee payable
monthly at the annual rate of .20% of the value of the Fund's average daily
net assets and (ii) as to Administrative Shares, Investor Shares and
Participant Shares, payments made pursuant to the Fund's Service Plan with
respect to each such class of shares at the annual rate set forth in the
Service Plan.  See "Service Plans."

     In addition, each Agreement provides that if in any fiscal year the
aggregate expenses of the Fund, exclusive of taxes, brokerage, interest on
borrowings and (with the prior written consent of the necessary state
securities commissions) extraordinary expenses, but including the management
fee, exceed 1-1/2% of the value of the Fund's average net assets for the
fiscal year, the Fund may deduct from the payment to be made to the Manager
under the Agreement, or the Manager will bear, such excess expense.  Such
deduction or payment, if any, will be estimated on a daily basis, and
reconciled and effected or paid, as the case may be, on a monthly basis.

     The aggregate of the fees payable to the Manager is not subject to
reduction as the value of the Fund's net assets increases.

     Distributor.  The Distributor, located at 60 State Street, Boston,
Massachusetts 02109, serves as each Fund's distributor on a best efforts
basis pursuant to an agreement which is renewable annually.

     Transfer and Dividend Disbursing Agent and Custodian.  Dreyfus
Transfer, Inc. (the "Transfer Agent"), a wholly-owned subsidiary of the
Manager, P.O. Box 9671, Providence, Rhode Island 02940-9671, is each Fund's
transfer and dividend disbursing agent.  Under a separate transfer agency
agreement with each Fund, the Transfer Agent arranges for the maintenance of
shareholder account records for the Fund, the handling of certain
communications between shareholders and the Fund and the payment of
dividends and distributions payable by the Fund.  For these services, the
Transfer Agent receives a monthly fee from each Fund computed on the basis
of the number of shareholder accounts it maintains for the Fund during the
month, and is reimbursed for certain out-of-pocket expenses.

     The Bank of New York (the "Custodian"), 90 Washington Street, New York,
New York 10286, is each Fund's custodian.  The Custodian has no part in
determining the investment policies of the Funds or which securities are to
be purchased or sold by a Fund.  Under a separate custody agreement with
each Fund, the Custodian holds the Fund's securities and keeps all necessary
accounts and records.  For its custody services, the Custodian receives a
monthly fee from each Fund based on the market value of the Fund's assets
held in custody and receives certain securities transactions charges.


                              HOW TO BUY SHARES

     Each Fund offers four classes of shares--Institutional Shares,
Administrative Shares,  Investor Shares and Participant Shares.  The classes
are identical, except as to the services offered to each class and the
expenses borne by each class which may affect performance. See "Service Plan."

     The Funds are designed for institutional investors, particularly banks,
acting for themselves or in a fiduciary, advisory, agency, custodial or
similar capacity.  Fund shares may not be purchased directly by individuals,
although institutions may purchase shares for accounts maintained by
individuals.  Generally, each investor will be required to open a single
master account with the Fund for all purposes.  In certain cases, the Fund
may request investors to maintain separate master accounts for shares held
by the investor (i) for its own account, for the account of other
institutions and for accounts for which the institution acts as a fiduciary,
and (ii) for accounts for which the investor acts in some other capacity.
An institution may arrange with the Transfer Agent for sub-accounting
services and will be charged directly for the cost of such services.
Institutions purchasing Fund shares have agreed to transmit copies of the
Fund's Prospectus and all relevant Fund materials, including proxy
materials, to each individual or entity for whose account the shares were
purchased, to the extent required by law.

     The minimum initial investment is $10,000,000, unless: (a) the investor
has invested at least $10,000,000 in the aggregate among any class of shares
of any Fund or Dreyfus Institutional Short Term Treasury Fund; or (b) the
investor has, in the opinion of Dreyfus Institutional Services Division,
adequate intent and availability of funds to reach a future level of
investment of $10,000,000 among any class of shares of the funds identified
above.  There is no minimum for subsequent purchases.  The initial
investment must be accompanied by the Account Application.  Share
certificates are issued only upon the investor's written request.  No
certificates are issued for fractional shares.  Each Fund reserves the right
to reject any purchase order.

     Management understands that some financial institutions, securities
dealers and other industry professionals (collectively, "Service Agents")
and other institutions may charge their clients fees in connection with
purchases for the accounts of their clients.  Service Agents may receive
different levels of compensation for selling different classes of shares.
Investors should consult their Service Agents in this regard.

     Fund shares may be purchased by wire, by telephone or through a
compatible automated interface or trading system.  All payments should be
made in U.S. dollars and, to avoid fees and delays, should be drawn only on
U.S. banks.  To place an order by telephone or to determine whether their
automated facilities are compatible with the Fund's, investors should call
Dreyfus Institutional Services Division at one of the telephone numbers
listed on the cover.

     Fund shares are sold on a continuous basis at the net asset value per
share next determined after an order in proper form and Federal Funds
(monies of member banks in the Federal Reserve System which are held on
deposit at a Federal Reserve Bank) are received by the Custodian or other
authorized entity to receive orders on behalf of the Fund.  If an investor
does not remit Federal Funds, its payment must be converted into Federal
Funds.  This usually occurs within one business day of receipt of a bank
wire and within two business days of receipt of a check drawn on a member
bank of the Federal Reserve System.  Checks drawn on banks which are not
members of the Federal Reserve System may take considerably longer to
convert into Federal Funds.  Prior to receipt of Federal Funds, the
investor's money will not be invested.  Net asset value per share of each
class of shares is computed by dividing the value of the Fund's net assets
represented by such class (i.e., the value of its assets less liabilities)
by the total number of shares of such class outstanding.  See "Determination
of Net Asset Value."

     Taxable Funds--Each of these Funds' net asset value per share is
determined twice daily:  (i) as of 5:00 p.m., New York time, and (ii) as of
8:00 p.m., New York time, on each day the New York Stock Exchange  or, as to

New York time, by a means other than an automated interface or trading
system will become effective on the following business day.

     Using Federal Funds.  The Transfer Agent or the Fund may attempt to
notify the investor upon receipt of checks drawn on banks that are not
members of the Federal Reserve System as to the possible delay in conversion
into Federal Funds, and may attempt to arrange for a better means of
transmitting the money.  If the investor is a customer of a securities
dealer, bank or other financial institution and an order to purchase Fund
shares is paid for other than in Federal Funds, the securities dealer, bank
or other financial institution, acting on behalf of its customer, will
complete the conversion into, or itself advance, Federal Funds generally on
the business day following receipt of the customer order.  The order is
effective only when so converted and received by the Custodian.


                                SERVICE PLANS
                 (ADMINISTRATIVE SHARES, INVESTOR SHARES AND
                          PARTICIPANT SHARES ONLY)

     Each Fund has adopted a Service Plan pursuant to Rule 12b-1 under the
1940 Act (the "Rule") for its Administrative Shares, Investor Shares and
Participant Shares.  The Rule provides, among other things, that an
investment company may bear expenses of distributing its shares only
pursuant to a plan adopted in accordance with the Rule.  The  Board has
adopted a separate plan (the "Service Plan") with respect to each Fund's
Administrative Shares, Investor Shares and Participant Shares pursuant to
which the Fund (a) reimburses the Distributor for distributing such classes
of shares and (b) pays the Manager, Dreyfus Service Corporation and any
affiliate of either of them (collectively, "Dreyfus") for advertising and
marketing and for providing certain services to shareholders of the
respective class of shares.   These services include answering shareholder
inquiries regarding the Fund and providing reports and other information,
and services related to the maintenance of shareholders accounts
("Servicing").  Under the Service Plan, as to each relevant class, the
Distributor and Dreyfus may make payments to Service Agents in respect to
these services.   Generally, the Service Agent will provide holders of
Administrative, Investor or Participant Shares a consolidated statement.
The Service Agent generally also will provide the holders of Investor or
Participant Shares checkwriting privileges and, in the case of Participant
Shares, automated teller machine access, and bill paying services.   The
amount paid under the Service Plan for Servicing is intended to be a
"service fee" as defined under the Conduct Rules of the National Association
of Securities Dealers, Inc. (the "NASD"), and at no time will such amount
exceed the maximum amount permitted to be paid under the NASD Conduct Rules
as a service fee.  The fees payable under the Service Plan are payable
without regard to actual expenses incurred.  The Board believes that there
is a reasonable likelihood that each Fund's Service Plan will benefit such
Fund and the holders of its Administrative Shares, Investor Shares and
Participant Shares.

     A quarterly report of the amounts expended under each Service Plan, and
the purposes for which such expenditures were incurred, must be made to the
respective Board for its review.  In addition, each Service Plan provides
that it may not be amended to increase materially the costs which holders of
Administrative Shares, Investor Shares, or Participant Shares may bear
pursuant to the Service Plan without the approval of the holders of such
class of shares and that other material amendments of the Service Plan must
be approved by the  Board, and by the Board members who are not "interested
persons" (as defined in the 1940 Act) of the Fund and have no direct or
indirect financial interest in the operation of the Service Plan or in any
agreements entered into in connection with the Service Plan, by vote cast in
person at a meeting called for the purpose of considering such amendments.
Each Service Plan is subject to annual approval by such vote of its Board
members cast in person at a meeting called for the purpose of voting on the
Service Plan.  Board members of each Fund last so approved the Fund's
Service Plan at a meeting held on May 19, 1999.  Each Service Plan may be
terminated at any time as to a class of shares by vote of a majority of the
Board members who are not "interested persons" and have no direct or
indirect financial interest in the operation of the Service Plan or in any
agreements entered into in connection with the Service Plan or by vote of
the holders of a majority of such class of shares.

     Set forth below are the total amounts paid by each Fund pursuant to its
Service Plan to (i) the Distributor as reimbursement for distributing
Administrative Shares, Investor Shares, and Participant Shares ("Distributor
Payments") and (ii) Dreyfus for advertising and marketing and for providing
services to holders of such classes of shares ("Dreyfus Payments"), for the
fiscal year ended January 31, 1999 are as follows:

                         SHAREHOLDER SERVICES PLANS
                         (INSTITUTIONAL SHARES ONLY)

     Each Fund, as to its Institutional Shares only, has adopted a separate
Shareholder Services Plan (the "Plan") pursuant to which the Fund has agreed
to reimburse Dreyfus Service Corporation an amount not to exceed the annual
rate of .25% of the value of the Fund's average daily net assets
attributable to Institutional Shares for certain allocated expenses of
providing personal services and/or maintaining shareholder accounts.  The
services provided to holders of Institutional Shares may include personal
services relating to shareholder accounts, such as answering shareholder
inquiries regarding the Fund and providing reports and other information,
and services related to the maintenance of shareholder accounts.

     A quarterly report of the amounts expended under each Plan and the
purposes for which such expenditures were incurred, must be made to the
respective Board for its review.  In addition, each Plan provides that
material amendments of the Plan must be approved by the Fund's Board, and by
the Board members who are not "interested persons" (as defined in the 1940
Act) of the Fund or the Manager and have no direct or indirect financial
interest in the operation of the Plan, by vote cast in person at a meeting
called for the purpose of considering such amendments.  Each Plan is subject
to annual approval by such vote of the Board members of such Fund cast in
person at a meeting called for the purpose of voting on the Plan.  Board
members of each Fund last so approved the Fund's Plan at a meeting held on
May 19, 1999.  Each Plan is terminable at any time by vote of a majority of
the Board members who are not "interested persons" and have no direct or
indirect financial interest in the operation of the Plan.

     The total amounts payable by each Fund pursuant to its Plan with
respect to Institutional Shares for its most recent fiscal year were borne
by the Manager pursuant to an agreement in effect.  See "Management
Arrangements."

                            HOW TO REDEEM SHARES

     General.  Each Fund ordinarily will make payment for shares redeemed
within seven days after receipt by Dreyfus Institutional Services Division
or other authorized entity of a redemption request in proper form, except as
provided by the rules of the Securities and Exchange Commission.

Dreyfus Cash Management, Dreyfus Cash Management Plus, Dreyfus Government
Cash Management, Dreyfus Government Prime Cash Management, Dreyfus Treasury
Cash Management and Dreyfus Treasury Prime Cash Management--If a redemption
request is received in proper form, and transmitted to the Custodian by 5:00
p.m., New York time, the proceeds of the redemption, if transfer by wire is
requested, ordinarily will be transmitted in Federal Funds on the same day
and the shares will not receive the dividend declared on that day.  A
redemption request effected through an automated interface or trading system
after 5:00 p.m., New York time, but prior to 8:00 p.m., New York time, will
be effective on that day, the shares will receive the dividend declared on
that day, and the proceeds of redemption, if wire transfer is requested,
ordinarily will be transmitted in Federal Funds on the next business day.  A
redemption request in proper form effected between 5:00 p.m. and 8:00 p.m.,
New York time, by a means other than an automated interface or trading
system will not be effective until the following business day.

Dreyfus Municipal Cash Management Plus, Dreyfus Tax Exempt Cash Management
and Dreyfus New York Municipal Cash Management--If a redemption request is
received in proper form, and transmitted to the Custodian by 12:00 Noon, New
York time, the proceeds of the redemption, if transfer by wire is requested,
ordinarily will be transmitted in Federal Funds on the same day and the
shares will not receive the dividend declared on that day.  A redemption
request effected through an automated interface or trading system after
12:00 Noon, New York time, but prior to 8:00 p.m., New York time, will be
effective on that day, the shares will receive the dividend declared on that
day, and the proceeds of redemption, if wire transfer is requested,
ordinarily will be transmitted in Federal Funds on the next business day.  A
redemption request in proper form effected between 12:00 Noon and 8:00 p.m.,
New York time, by a means other than an automated interface or trading
system will not be effective until the following business day.

     Redemption by Wire or Telephone.  By using this procedure, the investor
authorizes the Transfer Agent to act on wire or telephone redemption
instructions from any person representing himself or herself to be an
authorized representative of the investor, and reasonably believed by the
Transfer Agent to be genuine.  Redemption proceeds will be transferred by
Federal Reserve wire only to a bank that is a member of the Federal Reserve
System.

     Investors with access to telegraphic equipment may wire redemption
requests to the Transfer Agent by employing the following transmittal code
which may be used for domestic or overseas transmission:

                                 Transfer Agent's
Transmittal Code                 Answer Back Sign
________________                 ________________

144295                           144295 TSSG PREP

     Investors who do not have direct access to telegraphic equipment may
have the wire transmitted by contacting a TRT Cables operator at 1-800-654-
7171, toll free.  Investors should advise the operator that the above
transmittal code must be used and should also inform the operator of the
Transfer Agent's answer back sign.

     Redemption Commitment.  Each Fund has committed to pay in cash all
redemption requests by any shareholder of record, limited in amount during
any 90-day period to the lesser of $250,000 or 1% of the value of the Fund's
net assets at the beginning of such period.  Such commitment is irrevocable
without the prior approval of the Securities and Exchange Commission and is
a fundamental policy of the Fund which may not be changed without
shareholder approval.  In the case of requests for redemption in excess of
such amount, the Board reserves the right to make payments in whole or in
part in securities or other assets of the Fund in case of an emergency or
any time a cash distribution would impair the liquidity of the Fund to the
detriment of the existing shareholders.  In such event, the securities would
be valued in the same manner as the Fund's portfolio is valued.  If the
recipient sells such securities, brokerage charges might be incurred.

     Suspension of Redemptions.  The right of redemption may be suspended or
the date of payment postponed with respect to any Fund (a) during any period
when the New York Stock Exchange is closed (other than customary weekend and
holiday closings), (b) when trading in the markets the Fund ordinarily
utilizes is restricted, or when an emergency exists as determined by the
Securities and Exchange Commission so that disposal of the Fund's
investments or determination of its net asset value is not reasonably
practicable, or (c) for such other periods as the Securities and Exchange
Commission by order may permit to protect the Fund's investors.


                      DETERMINATION OF NET ASSET VALUE

     Amortized Cost Pricing.  The valuation of each Fund's portfolio
securities is based upon their amortized cost which does not take into
account unrealized capital gains or losses. This involves valuing an
instrument at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium, regardless of the impact of fluctuating
interest rates on the market value of the instrument.  While this method
provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price
the Fund would receive if it sold the instrument.

     Each Fund's Board has established, as a particular responsibility
within the overall duty of care owed to the Fund's investors, procedures
reasonably designed to stabilize the Fund's price per share as computed for
the purpose of purchases and redemptions at $1.00.  Such procedures include
review of the Fund's portfolio holdings by the Fund's Board, at such
intervals as it deems appropriate, to determine whether the Fund's net asset
value calculated by using available market quotations or market equivalents
deviates from $1.00 per share based on amortized cost.  In such review,
investments for which market quotations are readily available will be valued
at the most recent bid price or yield equivalent for such securities or for
securities of comparable maturity, quality and type, as obtained from one or
more of the major market makers for the securities to be valued.  Other
investments and assets, to the extent a Fund is permitted to invest in such
instruments, will be valued at fair value as determined in good faith by the
Fund's Board.  With respect to the Tax Exempt Funds, market quotations and
market equivalents used in the Board's review are obtained from an
independent pricing service (the "Service") approved by the Board.  The
Service values these Funds' investments based on methods which include
consideration of:  yields or prices of municipal obligations of comparable
quality, coupon, maturity and type; indications of values from dealers; and
general market conditions.  The Service also may employ electronic data
processing techniques and/or a matrix system to determine valuations.

     The extent of any deviation between the Fund's net asset value per
share based upon available market quotations or market equivalents and $1.00
per share based on amortized cost will be examined by the Fund's Board.  If
such deviation exceeds 1/2%, the Fund's Board will consider promptly what
action, if any, will be initiated.  In the event the Fund's Board determines
that a deviation exists which may result in material dilution or other
unfair results to investors or existing shareholders, it has agreed to take
such corrective action as it regards as necessary and appropriate including:
selling portfolio instruments prior to maturity to realize capital gains or
losses or to shorten average portfolio maturity; withholding dividends or
paying distributions from capital or capital gains; redeeming shares in
kind; or establishing a net asset value per share by using available market
quotations or market equivalents.

     New York Stock Exchange and Transfer Agent Closings.  The holidays (as
observed) on which both the New York Stock Exchange and the Transfer Agent
are closed currently are: New Year's Day, Martin Luther King Jr. Day,
Presidents' Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and
Christmas.  The New York Stock Exchange also is closed on Good Friday.

                            SHAREHOLDER SERVICES

     Fund Exchanges.  Shares of one class of a Fund may be exchanged for
shares of the same class of another Fund or of Dreyfus Institutional Short
Term Treasury Fund (which offers Institutional Shares and Investor Shares
only).  To request an exchange, exchange instructions must be given in
writing or by telephone.  By using the Telephone Exchange Privilege, the
investor authorizes the Transfer Agent to act on exchange instructions from
any person representing himself or herself to be an authorized
representative of the investor and reasonably believed by the Transfer Agent
to be genuine.  Telephone exchanges may be subject to limitations as to the
amount involved or the number of telephone exchanges permitted.  Shares will
be exchanged at the net asset value next determined after receipt of an
exchange request in proper form.  Shares in certificate form are not
eligible for telephone exchange.

     An investor who wishes to redeem shares of one class of shares and
purchase shares of another class of shares of a fund identified above should
contact Dreyfus Institutional Services Division by calling one of the
telephone numbers listed on the cover page of this Statement of Additional
Information, and should obtain a prospectus for the relevant share class
which the investor wishes to purchase.

     No fees currently are charged shareholders directly in connection with
exchanges, although each Fund reserves the right, upon not less than 60
days' written notice, to charge shareholders a nominal administrative fee in
accordance with rules promulgated by the Securities and Exchange Commission.

     Dreyfus Auto-Exchange Privilege.  Dreyfus Auto-Exchange Privilege
permits an investor to purchase, in exchange for shares of one class of a
Fund, shares of the same class of another Fund or of Dreyfus Institutional
Short Term Treasury Fund (which offers Institutional Shares and Investor
Shares only), if the investor is a shareholder in such fund.  This Privilege
is available only for existing accounts.  Shares will be exchanged on the
basis of relative net asset value.  Enrollment in or modification or
cancellation of this Privilege is effective three business days following
notification by the investor.  An investor will be notified if its account
falls below the amount designated under this Privilege.  In this case, an
investor's account will fall to zero unless additional investments are made
in excess of the designated amount prior to the next Auto-Exchange
transaction.  Shares in certificate form are not eligible for this
Privilege.

     Fund Exchanges and the Dreyfus Auto-Exchange Privilege are available to
investors resident in any state in which shares of the fund being acquired
may legally be sold.  Shares may be exchanged only between accounts having
identical names and other identifying designations.

     The Fund reserves the right to reject any exchange request in whole or
in part.  The availability of Fund Exchanges or the Dreyfus Auto-Exchange
Privilege may be modified or terminated at any time upon notice to
investors.

                     DIVIDENDS, DISTRIBUTIONS AND TAXES

     Management believes that each Fund has qualified for the fiscal year
ended January 31, 1999 as a "regulated investment company" under the Code.
The Fund intends to continue to so qualify if such qualification is in the
best interests of its shareholders.  Such qualification relieves the Fund of
any liability for Federal income tax to the extent its earnings are
distributed in accordance with applicable provisions of the Code.  If the
Fund did not qualify as a regulated investment company, it would be treated
for tax purposes as an ordinary corporation subject to Federal income tax.

     Ordinarily, gains and losses realized from portfolio transactions will
be treated as capital gain or loss.  However, all or a portion of any gains
realized from the sale or other disposition of certain market discount bonds
will be treated as ordinary income under Section 1276 of the Code.

     Many states grant tax-free status to dividends paid to shareholders of
mutual funds from interest income earned by a fund from direct obligations
of the U.S. Government, subject in some states to minimum investment
requirements that must be met by the fund.  Investments in securities issued
by the Government National Mortgage Association or the Federal National
Mortgager Association, bankers' acceptances, commercial paper and repurchase
agreements collateralized by U.S. Government securities do not generally
qualify for tax-free treatment.  At the end of each calendar year, as
applicable, investors will be provided with the percentage of any dividends
paid that may qualify for such tax-free treatment.   Investors should then
consult with their tax advisers with respect to the application of state and
local laws to these distributions.

                           PORTFOLIO TRANSACTIONS

     Portfolio securities ordinarily are purchased directly from the issuer
or from an underwriter or a market maker for the securities.  Usually no
brokerage commissions are paid by any Fund for such purchases.  Purchases
from underwriters of portfolio securities include a concession paid by the
issuer to the underwriter and the purchase price paid to, and sales price
received from, market makers for the securities may include the spread
between the bid and asked price.  No brokerage commissions have been paid by
any Fund to date.

     Transactions are allocated to various dealers by the portfolio managers
of a Fund in their best judgment.  The primary consideration is prompt and
effective execution of orders at the most favorable price. Subject to that
primary consideration, dealers may be selected for research, statistical or
other services to enable the Manager to supplement its own research and
analysis with the views and information of other securities firms and may be
selected based upon their sales of shares of a Fund or other funds advised
by the Manager or its affiliates.

     Research services furnished by brokers through which a Fund effects
securities transactions may be used by the Manager in advising other funds
it advises and, conversely, research services furnished to the Manager by
brokers in connection with other funds the Manager advises may be used by
the Manager in advising each Fund.  Although it is not possible to place a
dollar value on these services, it is the opinion of the Manager that the
receipt and study of such services should not reduce the overall expenses of
its research department.

     Yield is computed in accordance with a standardized method which
involves determining the net change in the value of a hypothetical pre-
existing Fund account having a balance of one share at the beginning of a
seven calendar day period for which yield is to be quoted, dividing the net
change by the value of the account at the beginning of the period to obtain
the base period return, and annualizing the results (i.e., multiplying the
base period return by 365/7).  The net change in the value of the account
reflects the value of additional shares purchased with dividends declared on
the original share and any such additional shares and fees that may be
charged to shareholder accounts, in proportion to the length of the base
period and the Fund's average account size, but does not include realized
gains and losses or unrealized appreciation and depreciation.  Effective
yield is computed by adding 1 to the base period return (calculated as
described above), raising that sum to a power equal to 365 divided by 7, and
subtracting 1 from the result.  Both yield figures take into account any
applicable distribution and service fees.  As a result, at any given time,
the performance of Administrative Shares, Investor Shares and Participant
Shares should be expected to be lower than that of Institutional Shares, the
performance of Investor Shares and Participant Shares should be expected to
be lower than that of Administrative Shares and the performance of
Participant Shares should be expected to be lower than that of Investor
Shares.


     As to the Tax Exempt Funds, tax equivalent yield is computed by
dividing that portion of the yield or effective yield (calculated as
described above) which is tax exempt by 1 minus a stated tax rate and adding
the quotient to that portion, if any, of the yield of the Fund that is not
tax exempt.  Based upon a 1999 Federal income tax rate of 39.60%, the tax
equivalent yield for the 7-day period ended January 31, 1999 for
Institutional Shares, Administrative Shares, Investor Shares and Participant
Shares of Dreyfus Municipal Cash Management Plus and Dreyfus Tax Exempt Cash
Management was as follows:

     The tax equivalent yields noted above for Dreyfus Municipal Cash
Management Plus and Dreyfus Tax Exempt Cash Management represent the
application of the highest Federal marginal personal income tax rate
currently in effect.  The tax equivalent figures, however, do not include
the potential effect of any state or local (including, but not limited to,
county, district or city) taxes, including applicable surcharges.  The tax
equivalent yields noted above for Dreyfus Municipal Cash Management Plus
represent the application of the highest Federal, New York State and New
York City marginal personal income tax rates presently in effect.  For
Federal income tax purposes, a 39.60% rate has been used, and for New York
State and New York City personal income tax purposes, the rates of 7.875%
and 4.46%, respectively, have been used.  In addition, there may be pending
legislation which could affect such stated tax rates or yields.  Each
investor should consult its tax adviser, and consider its own factual
circumstances and applicable tax laws, in order to ascertain the relevant
tax equivalent yield.


     From time to time, each Tax Exempt Fund may use hypothetical tax
equivalent yields or charts in its advertising.  These hypothetical yields
or charts will be used for illustrative purposes only and not as
representative of the Fund's past or future performance.

     Yields will fluctuate and are not necessarily representative of future
results.  The investor should remember that yield is a function of the type
and quality of the instruments in the portfolio, portfolio maturity and
operating expenses.  An investor's principal in the Fund is not guaranteed.
See "Determination of Net Asset Value" for a discussion of the manner in
which a Fund's price per share is determined.

     From time to time, comparative performance information may be used in
advertising or marketing Fund shares, including data from Lipper Analytical
Services, Inc., Bank Rate MonitorT, IBC's Money Fund ReportT, IBC's Rated
Money Fund ReportT, Morningstar, Inc. and other industry publications.

     From time to time, advertising materials for a Fund may refer to or
discuss then-current or past economic conditions, developments and/or
events, or actual or proposed tax legislation.  From time to time,
advertising materials for a Fund may also refer to statistical or other
information concerning trends relating to investment companies, as compiled
by industry associations such as the Investment Company Institute.  From
time to time, advertising materials for a Fund also may discuss the
availability and benefits of offering the Funds as investment vehicles for
commercial sweep accounts, and may discuss statistics, data, and industry
trends in this regard.

     In early 1974, the Manager commenced offering the first money market
fund to be widely offered on a retail basis, Dreyfus Liquid Assets, Inc.
Money market mutual funds have subsequently grown into over a one trillion
dollar industry.


     Each Fund is a member of the Dreyfus Family of Cash Management Funds,
which are designed to meet the needs of an array of institutional investors.
As of April 27, 1999, the total net assets of all of the funds composing the
Dreyfus Family of Cash Management Funds amounted to approximately $27.5
billion.


                         INFORMATION ABOUT THE FUNDS

     Each Fund's shares are classified into four classes.  Each Fund share
has one vote and shareholders will vote in the aggregate and not by class,
except as otherwise required by law or with respect to any matter which
affects only one class.  Each Fund share, when issued and paid for in
accordance with the terms of the offering, is fully paid and nonassessable.
Fund shares have no preemptive, subscription or conversion rights and are
freely transferable.

     Under Massachusetts law, shareholders of a Fund (other than Dreyfus
Cash Management Plus, which is a Maryland Corporation) could, under certain
circumstances, be held liable for the obligations of the Fund.  However,
each Funds' Agreement and Declaration of Trust (each, a "Trust Agreement")
disclaims shareholder liability for acts or obligations of such Fund and
requires that notice of such disclaimer be given in each agreement,
obligation or instrument entered into or executed by the Fund or its
Trustees.  Each Trust Agreement provides for indemnification from the Fund's
property for all losses and expenses of any shareholder held personally
liable for the obligations of the Fund.  Thus, the risk of a shareholder's
incurring financial loss on account of shareholder liability is limited to
circumstances in which the Fund itself would be unable to meet its
obligations, a possibility which management believes is remote.  Upon
payment of any liability incurred by a Fund organized as a Massachusetts
business trust, the shareholder paying such liability will be entitled to
reimbursement from the general assets of such Fund.  Each of these Funds
intends to conduct its operations in such a way so as to avoid, as far as
possible, ultimate liability of its shareholders for liabilities of the
Fund.

     Unless otherwise required by the 1940 Act, ordinarily it will not be
necessary for the Fund to hold annual meetings of shareholders.  As a
result, Fund shareholders may not consider each year the election of Board
members or the appointment of auditors.  However, the holders of at least
10% of the shares outstanding and entitled to vote may require the Fund to
hold a special meeting of shareholders for purposes of removing a Board
member from office.  Fund shareholders may remove a Board member by the
affirmative vote of a majority, in the case of Dreyfus Cash Management Plus,
or two-thirds, in the case of each other Fund, of the Fund's outstanding
voting shares.  In addition, the Fund's Board will call a meeting of
shareholders for the purpose of electing Board members if, at any time, less
than a majority of the Board members then holding office have been elected
by shareholders.

     The Company is a "series fund," which is a mutual fund divided into
separate portfolios, each of which is treated as a separate entity for
certain matters under the 1940 Act and for other purposes.  A shareholder of
one portfolio is not deemed to be a shareholder of any other portfolio.  For
certain matters shareholders vote together as a group; as to others they
vote separately by portfolio.

     To date, the Company's Board has authorized the creation of two series
of shares.  All consideration received by the Company for shares of one of
the portfolios, and all assets in which such consideration is invested, will
belong to that portfolio (subject only to the rights of creditors of the
Company) and will be subject to the liabilities related thereto.  The income
attributable to, and the expenses of, one portfolio would be treated
separately from those of the other portfolio.  The Company has the ability
to create, from time to time, new series without shareholder approval.

     Rule 18f-2 under the 1940 Act provides that any matter required to be
submitted under the provisions of the 1940 Act or applicable state law or
otherwise to the holders of the outstanding voting securities of an
investment company, such as the Company, will not be deemed to have been
effectively acted upon unless approved by the holders of a majority of the
outstanding shares of each series affected by such matter.  Rule 18f-2
further provides that a series shall be deemed to be affected by a matter
unless it is clear that the interests of each series in the matter are
identical or that the matter does not affect any interest of such series.
However, the Rule exempts the selection of independent accountants and the
election of Board members from the separate voting requirements of the Rule.

     The Glass-Steagall Act and other applicable laws prohibit Federally
chartered or supervised banks from engaging in certain aspects of the
business of issuing, underwriting, selling and/or distributing securities.
Accordingly, banks will perform only administrative and shareholder
servicing functions.  While the matter is not free from doubt, each Fund's
Board believes that such laws should not preclude a bank from acting on
behalf of clients as contemplated by the Prospectuses or this Statement of
Additional Information.  However, judicial or administrative decisions or
interpretations of such laws, as well as changes in either Federal or state
statutes or regulations relating to the permissible activities of banks and
their subsidiaries or affiliates, could prevent a bank from continuing to
perform all or a part of the activities contemplated by the Prospectuses or
this Statement of Additional Information.  If a bank were prohibited from so
acting, its shareholder clients would be permitted to remain Fund
shareholders and alternative means for continuing the servicing of such
shareholders would be sought.  In such event, changes in the operation of a
Fund might occur and shareholders serviced by such bank might no longer be
able to avail themselves of any automatic investment or other services then
being provided by the bank.   The Funds do not expect that their respective
shareholders would suffer any adverse financial consequences as a result of
any of these occurrences.

     Although each Fund is offering only its own shares, it is possible that
a Fund might become liable for any misstatement in the combined Prospectuses
or this Statement of Additional Information about another Fund.  The Board
members with respect to each Fund have considered this factor in approving
the use of the combined Prospectuses and this Statement of Additional
Information.

     Each Fund sends annual and semi-annual financial statements to all its
shareholders.


                      COUNSEL AND INDEPENDENT AUDITORS

     Stroock & Stroock & Lavan LLP, 180 Maiden Lane, New York 10038-4982, as
counsel for each Fund, has rendered its opinion as to certain legal matters
regarding the due authorization and valid issuance of the shares being sold
pursuant to the Funds' Prospectuses.


     Ernst & Young LLP, independent auditors, have been selected as
independent auditors of each Fund.

     Descriptions of the highest commercial paper, bond and other short- and
long-term rating categories assigned by Standard & Poor's Ratings Group
("S&P"), Moody's Investors Service, Inc. ("Moody's"), Fitch IBCA, Inc.
("Fitch"), Duff & Phelps Credit Rating Co. ("Duff"), and Thomson BankWatch,
Inc. ("BankWatch").

Commercial Paper Ratings and Short-Term Ratings

     The designation A-1 by S&P indicates that the degree of safety
regarding timely payment is either overwhelming or very strong.  Those
issues determined to possess overwhelming safety characteristics are denoted
with a plus sign (+) designation.

     The rating Prime-1 (P-1) is the highest commercial paper rating
assigned by Moody's.  Issuers of P-1 paper must have a superior capacity for
repayment of short-term promissory obligations, and ordinarily will be
evidenced by leading market positions in well established industries, high
rates of return on funds employed, conservative capitalization structures
with moderate reliance on debt and ample asset protection, broad margins in
earnings coverage of fixed financial charges and high internal cash
generation, and well established access to a range of financial markets and
assured sources of alternate liquidity.

     The rating Fitch-1 (Highest Credit Quality) is the highest commercial
paper rating assigned by Fitch and indicates the strongest capacity for
timely payment of financial commitments.

     The rating Duff-1 is the highest commercial paper rating assigned by
Duff.  Paper rated Duff-1 is regarded as having very high certainty of
timely payment with excellent liquidity factors which are supported by ample
asset protection.  Risk factors are minor.

     The rating TBW-1 is the highest short-term obligation rating assigned
by BankWatch.  Obligations rated TBW-1 are regarded as having the strongest
capacity for timely repayment.

     In addition to ratings of short-term obligations, BankWatch assigns a
rating to each issuer it rates, in gradations of A through F.  BankWatch
examines all segments of the organization including, where applicable, the
holding company, member banks or associations, and other subsidiaries.  In
those instances where financial disclosure is incomplete or untimely, a
qualified rating (qr) is assigned to the institution.  BankWatch also
assigns, in the case of foreign banks, a country rating which represents an
assessment of the overall political and economic stability of the country in
which that bank is domiciled.


Bond Ratings and Long-Term Ratings

     Bonds rated AAA are considered by S&P to be the highest grade
obligation and possess an extremely strong capacity to pay principal and
interest.

     Bonds rated Aaa are judged by Moody's to be of the best quality. Bonds
rated Aa by Moody's are judged by Moody's to be of high quality by all
standards and, together with the Aaa group, they comprise what are generally
known as high-grade bonds.

     Bonds rated AAA by Fitch are judged by Fitch to be of the highest
credit quality.  The AAA rating by Fitch denotes the lowest expectation of
credit risk.  The AAA rating is assigned by Fitch only in case of
exceptionally strong capacity for timely payment of financial commitments;
the capacity is highly unlikely to be adversely affected by foreseeable
events.

     Bonds rated AAA by Duff are considered to be of the highest credit
quality.  The risk factors are negligible, being only slightly more than
U.S. Treasury debt.

     Fitch also assigns a rating to certain international and U.S. banks. A
Fitch bank rating represents Fitch's current assessment of the strength of
the bank and whether such bank would receive support should it experience
difficulties.  In its assessment of a bank, Fitch uses a dual rating system
comprised of Legal Ratings and Individual Ratings.  In addition, Fitch
assigns banks Long and Short-Term Ratings as used in the corporate ratings
discussed above.  Legal Ratings, which range in gradation from 1 through 5,
address the question of whether the bank would receive support provided by
central banks or the bank's shareholders if it experienced difficulties, and
such ratings are considered by Fitch to be a prime factor in its assessment
of credit risk.  Individual Ratings, which range in gradations from A
through E, represent Fitch's assessment of a bank's economic merits and
address the question of how the bank would be viewed if it were entirely
independent and could not rely on support from state authorities or its
owners.

                                 APPENDIX B
                             (TAX EXEMPT FUNDS)


     Description of certain S&P, Moody's and Fitch ratings:

S&P

Municipal Bond Ratings

     An S&P municipal bond rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation.

     The ratings are based on current information furnished by the issuer or
obtained by S&P from other sources it considers reliable, and will include:
(1) likelihood of default-capacity and willingness of the obligor as to the
timely payment of interest and repayment of principal in accordance with the
terms of the obligation; (2) nature and provisions of the obligation; and
(3) protection afforded by, and relative position of, the obligation in the
event of bankruptcy, reorganization or other arrangement under the laws of
bankruptcy and other laws affecting creditors' rights.

                                     AAA

     Debt rated AAA has the highest rating assigned by S&P.  Capacity to pay
interest and repay principal is extremely strong.

                                     AA

     Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.
The AA rating may be modified by the addition of a plus or a minus sign,
which is used to show relative standing within the category.

Municipal Note Ratings

                                    SP-1

     The issuers of these municipal notes exhibit very strong or strong
capacity to pay principal and interest.  Those issues determined to possess
overwhelming safety characteristics are given a plus (+) designation.

Commercial Paper Ratings

     The rating A is the highest rating and is assigned by S&P to issues
that are regarded as having the greatest capacity for timely payment. Issues
in this category are delineated with the numbers 1, 2 and 3 to indicate the
relative degree of safety.  Paper rated A-1 indicates that the degree of
safety regarding timely payment is either overwhelming or very strong.
Those issues determined to possess overwhelming safety characteristics are
denoted with a plus sign (+) designation.

Moody's

Municipal Bond Ratings

                                     Aaa

     Bonds which are rated Aaa are judged to be of the best quality.  They
carry the smallest degree of investment risk and are generally referred to
as "gilt edge."  Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure.  While the various
protective elements are likely to change, such changes as can be visualized
are most unlikely to impair the fundamentally strong position of such
issues.

                                     Aa

     Bonds which are rated Aa are judged to be of high quality by all
standards.  Together with the Aaa group they comprise what generally are
known as high grade bonds.  They are rated lower than the best bonds because
margins of protection may not be as large as in Aaa securities or
fluctuation of protective elements may be of greater amplitude or there may
be other elements present which make the long-term risks appear somewhat
larger than in Aaa securities.  Generally, Moody's provides either a generic
rating or a rating with a numerical modifier of 1 for bonds in each of the
generic rating categories Aa, A, Baa, Ba and B. Moody's also provides
numerical modifiers of 2 and 3 in each of these categories for bond issues
in health care, higher education and other not-for-profit sectors; the
modifier 1 indicates that the issue ranks in the higher end of its generic
rating category; the modifier 2 indicates that the issue is in the mid-range
of the generic category; and the modifier 3 indicates that the issue is in
the low end of the generic category.

Municipal Note Ratings

     Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade (MIG).  Such ratings recognize
the difference between short-term credit risk and long-term risk.  Factors
affecting the liquidity of the borrower and short-term cyclical elements are
critical in short-term ratings, while other factors of major importance in
bond risk, long-term secular trends for example, may be less important over
the short run.

     A short-term rating may also be assigned on an issue having a demand
feature.  Such ratings will be designated as VMIG or, if the demand feature
is not rated, as NR.  Short-term ratings on issues with demand features are
differentiated by the use of the VMIG symbol to reflect such characteristics
as payment upon periodic demand rather than fixed maturity dates and payment
relying on external liquidity.  Additionally, investors should be alert to
the fact that the source of payment may be limited to the external liquidity
with no or limited legal recourse to the issuer in the event the demand is
not met.

     Moody's short-term ratings are designated Moody's Investment Grade as
MIG 1 or VMIG 1 through MIG 4 or VMIG 4.  As the name implies, when Moody's
assigns a MIG or VMIG rating, all categories define an investment grade
situation.

                                MIG 1/VMIG 1

     This designation denotes best quality.  There is present strong
protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.

                                MIG 2/VMIG 2

     This designation denotes high quality.  Margins of protection are ample
although not so large as in the preceding group.

Commercial Paper Ratings

     The rating Prime-1 (P-1) is the highest commercial paper rating
assigned by Moody's.  Issuers of P-1 paper must have a superior capacity for
repayment of short-term promissory obligations, and ordinarily will be
evidenced by leading market positions in well established industries, high
rates of return on funds employed, conservative capitalization structures
with moderate reliance on debt and ample asset protection, broad margins in
earnings coverage of fixed financial charges and high internal cash
generation, and well established access to a range of financial markets and
assured sources of alternate liquidity.  Issuers rated Prime-2 (P-2) have a
strong ability for repayment of senior short-term debt obligations.
Capitalization characteristics, while still appropriate, may be more
affected by external conditions.  Ample alternate liquidity is maintained.

Fitch

Municipal Bond Ratings

     The ratings represent Fitch's assessment of the issuer's ability to
meet the obligations of a specific debt issue or class of debt.  The ratings
take into consideration special features of the issue, its relationship to
other obligations of the issuer, the current financial condition and
operative performance of the issuer and of any guarantor, as well as the
political and economic environment that might affect the issuer's future
financial strength and credit quality.

                                     AAA

     Bonds rated AAA are considered to be investment grade and of the
highest credit quality.  The obligor has an exceptionally strong ability to
pay interest and repay principal, which is unlikely to be affected by
reasonably foreseeable events.

                                     AA

     Bonds rated AA are considered to be investment grade and of very high
credit quality. The obligor's ability to pay interest and repay principal is
very strong, although not quite as strong as bonds rated AAA.  Because bonds
rated in the AAA and AA categories are not significantly vulnerable to
foreseeable future developments, short-term debt of these issuers is
generally rated F-1+.  Plus (+) and minus (-) signs are used with the rating
symbol AA to indicate the relative position of a credit within the rating
category.

Short-Term Ratings

     Fitch's short-term ratings apply to debt obligations that are payable
on demand or have original maturities of up to three years, including
commercial paper, certificates of deposit, medium-term notes, and municipal
and investment notes.

     Although the credit analysis is similar to Fitch's bond rating
analysis, the short-term rating places greater emphasis than bond ratings on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.

                                    F-1+

     Exceptionally Strong Credit Quality.  Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

                                     F-1

     Very Strong Credit Quality.  Issues assigned this rating reflect an
assurance of timely payment only slightly less in degree than issues rated F-
1+.

                                     F-2

     Good Credit Quality.  Issues carrying this rating have a satisfactory
degree of assurance for timely payments, but the margin of safety is not as
great as the F-1+ and F-1 categories.

                (DREYFUS NEW YORK MUNICIPAL CASH MANAGEMENT)

                 INVESTING IN NEW YORK MUNICIPAL OBLIGATIONS

     RISK FACTORS--INVESTING IN NEW YORK MUNICIPAL OBLIGATIONS

     The following information is a summary of special factors affecting
investments in New York municipal obligations.  It does not purport to be a
complete description and is based on information from the Annual Information
Statement of the State of New York dated June 26, 1998 and a supplement
thereto dated November 4, 1998.  The factors affecting the financial
condition of New York State (the "State") and New York City (the "City") are
complex and the following description constitutes only a summary.

General

     New York is the third most populous state in the nation and has a
relatively high level of personal wealth.  The state's economy is diverse,
with a comparatively large share of the nation's finance, insurance,
transportation, communications and services employment, and a very small
share of the nation's farming and mining activity.  The State's location and
its excellent air transport facilities and natural harbors have made it an
important link in international commerce.  Travel and tourism constitute an
important part of the economy.  Like the rest of the nation, New York has a
declining proportion of its workforce engaged in manufacturing, and an
increasing proportion engaged in service industries.

     Services: The services sector, which includes entertainment, personal
services, such as health care and auto repairs, and business-related
services, such as information processing, law and accounting, is the State's
leading economic sector.  The services sector accounts for more than three
of every ten nonagricultural jobs in New York and has a noticeably higher
proportion of total jobs than does the rest of the nation.

     Manufacturing: Manufacturing employment continues to decline in
importance in New York, as in most other states, and New York's economy is
less reliant on this sector than is the nation.  The principal manufacturing
industries in recent years produced printing and publishing materials,
instruments and related products, machinery, apparel and finished fabric
products, electronic and other electric equipment, food and related
products, chemicals and allied products, and fabricated metal products.

     Trade: Wholesale and retail trade is the second largest sector in terms
of nonagricultural jobs in New York but is considerably smaller when
measured by income share.  Trade consists of wholesale businesses and retail
businesses, such as department stores and eating and drinking
establishments.

     Finance, Insurance and Real Estate: New York City is the nation's
leading center of banking and finance and, as a result, this is a far more
important sector in the State than in the nation as a whole.  Although this
sector accounts for under one-tenth of all nonagricultural jobs in the
State, it contributes over one-sixth of all nonfarm labor and proprietors'
income.

     Agriculture: Farming is an important part of the economy of large
regions of the State, although it constitutes a very minor part of total
State output.  Principal agricultural products of the State include milk and
dairy products, greenhouse and nursery products, apples and other fruits,
and fresh vegetables.  New York ranks among the nation's leaders in the
production of these commodities.

     Government: Federal, State and local government together are the third
largest sector in terms of nonagricultural jobs, with the bulk of the
employment accounted for by local governments.  Public education is the
source of nearly one-half of total state and local government employment.

     Relative to the nation, the State has a smaller share of manufacturing
and construction and a larger share of service-related industries.  The
State's finance, insurance, and real estate share, as measured by income, is
particularly large relative to the nation.  The State is likely to be less
affected than the nation as a whole during an economic recession that is
concentrated in manufacturing and construction, but likely to be more
affected during a recession that is concentrated in the service-producing
sector.

Economic Outlook

U. S. Economy

     Economic growth during both 1998 and 1999 is expected to be slower than
it was during 1997.  The financial and economic turmoil which started in
Asia and has spread to other parts of the world is expected to continue to
negatively affect U.S. trade balances throughout most of 1999.  In addition,
growth in domestic consumption, which has been a major driving force behind
the nation's strong economic performance in recent years, is expected to
slow in 1999 as consumer confidence retreats from historic highs and the
stock market ceases to provide large amounts of extra discretionary income.
However, the lower short-term interest rates which are expected to be in
force during 1999 should help prevent a recession.  The revised forecast
projects real GDP growth of 3.4 percent in 1998, moderately below the 1997
growth rate.  In 1999, real GDP growth is expected to fall further, to 1.6
percent.  The growth of nominal GDP is projected to decline from 5.9 percent
in 1997 to 4.6 percent in 1998 and 3.7 percent in 1999.  The inflation rate
is expected to drop to 1.7 percent in 1998 before rising to 2.7 percent in
1999.  The annual rate of job growth is expected to be 2.5 percent in 1998,
almost equaling the strong growth rate experienced in 1997.  In 1999,
however, employment growth is forecast to slow markedly, to 1.9 percent.
Growth in personal income and wages is expected to slow in 1998 and again in
1999.

State Economy

     Continued growth is projected in 1998 and 1999 for employment, wages,
and personal income, although, for 1999, a significant slowdown in the
growth rates of personal income and wages are expected.  The growth of
personal income is projected to rise from 4.7 percent in 1997 to 5.0 percent
in 1998, but then drop to 3.4 percent in 1999, in part because growth in
bonus payments is expected to moderate significantly, a distinct shift from
the unusually high increases of the last few years.  Overall employment
growth is expected to be 2.0 percent in 1998, the strongest in a decade, but
is expected to drop to 1.0 percent in 1999, reflecting the slowing growth of
the national economy, continued spending restraint in government, less
robust profitability in the financial sector and continued restructuring in
the manufacturing, health care, and banking sectors.

State Financial Plan

     The State Constitution requires the Governor to submit to the
legislature a balanced executive budget which contains a complete plan of
expenditures (the "State Financial Plan") for the ensuing fiscal year and
all moneys and revenues estimated to be available therefor, accompanied by
bills containing all proposed appropriations or reappropriations and any new
or modified revenue measures to be enacted in connection with the executive
budget.  A final budget must be approved before the statutory deadline of
April 1.  The State Financial Plan is updated quarterly pursuant to law.

1998-99 Fiscal Year

     The State's current fiscal year began on April 1, 1998 and ends on
March 31, 1999 and is referred to herein as the State's 1998-99 fiscal year.
The Legislature adopted the debt service component of the State budget for
the 1998-99 fiscal year on March 30, 1998 and the remainder of the budget on
April 18, 1998.  In the period prior to adoption of the budget for the
current fiscal year, the Legislature also enacted appropriations to permit
the State to continue its operations and provide for other purposes.  On
April 25, 1998, the Governor vetoed certain items that the Legislature added
to the Executive Budget.  The Legislature had not overridden any of the
Governor's vetoes as of the start of the legislative recess on June 19, 1998
(under the State Constitution, the Legislature can override one or more of
the Governor's vetoes with the approval of two-thirds of the members of each
house).

     General Fund disbursements in 1998-99 are now projected to grow by
$2.43 billion over 1997-98 levels, or $690 million more than proposed in the
Governor's Executive Budget, as amended.  The change in General Fund
disbursements from the Executive Budget to the enacted budget reflects
legislative additions (net of the value of the Governor's vetoes), actions
taken at the end of the regular legislative session, as well as spending
that was originally anticipated to occur in 1997-98 but is now expected to
occur in 1998-99.  The State projects that the 1998-99 State Financial Plan
is balanced on a cash basis, with an estimated reserve for future needs of
$761 million.

     The State's enacted budget includes several new multi-year tax
reduction initiatives, including acceleration of State-funded property and
local income tax relief for senior citizens under the School Tax Relief
Program (STAR), expansion of the child care income-tax credit for middle-
income families, a phased-in reduction of the general business tax, and
reduction of several other taxes and fees, including an accelerated phase-
out of assessments on medical providers.  The enacted budget also provides
for significant increases in spending for public schools, special education
programs, and for the State and City university systems.  It also allocates
$50 million for a new Debt Reduction Reserve Fund (DRRF) that may eventually
be used to pay debt service costs on or to prepay outstanding State-
supported bonds.

     The 1998-99 State Financial Plan projects a closing balance in the
General Fund of $1.42 billion that is comprised of a reserve of $761 million
available for future needs, a balance of $400 million in the Tax
Stabilization Reserve Fund (TSRF), a balance of $158 million in the
Community Projects Fund (CPF), and a balance of $100 million in the
Contingency Reserve Fund (CRF).  The TSRF can be used in the event of an
unanticipated General Fund cash operating deficit, as provided under the
State Constitution and State Finance Law.  The CPF is used to finance
various legislative and executive initiatives.  The CRF provides resources
to help finance any extraordinary litigation costs during the fiscal year.

     Many complex political, social and economic forces influence the
State's economy and finances, which may in turn affect the State's Financial
Plan.  These forces may affect the State unpredictably from fiscal year to
fiscal year and are influenced by governments, institutions, and
organizations that are not subject to the State's control.  The State
Financial Plan is also necessarily based upon forecasts of national and
State economic activity.  Economic forecasts have frequently failed to
predict accurately the timing and magnitude of changes in the national and
the State economies.  The Division of Budget believes that its projections
of receipts and disbursements relating to the current State Financial Plan,
and the assumptions on which they are based, are reasonable.  Actual
results, however, could differ materially and adversely from the projections
set forth herein, and those projections may be changed materially and
adversely from time to time.  See "Special Considerations" below for a
discussion of risks and uncertainties faced by the State.

Second Update (current fiscal year)

     On October 30, 1998, the State issued the second of its three quarterly
updates to the 1998-99 Financial Plan.  In the Mid-Year Update, the State
continues to project that the State Financial Plan for 1998-99 will remain
in balance.  The State now projects total receipts in 1998-99 of $37.84
billion, an increase of $29 million over the amount projected in the First
Quarterly Update.  The State has made no changes to its July disbursement
projections, with total disbursements of $36.78 billion expected for the
current fiscal year.  The additional receipts increase the State's projected
surplus (reserve for future needs) by $29 million over the July estimate, to
$1.04 billion.

     The Financial Plan now projects a closing balance in the General Fund
of $1.7 billion.  The balance is comprised of the $1.04 billion reserve for
future needs, $400 million in the Tax Stabilization Reserve Fund, $100
million in the Contingency Reserve Fund (after a planned deposit of $32
million in 1998-99), and $158 million in the Community Projects Fund.

     The State ended the first six months of 1998-99 fiscal year with a
General Fund cash balance of $5.02 billion, roughly $143 million higher than
projected in the cash flow accompanying the July Update to the Financial
Plan.  Total receipts, including transfers from other funds, were
approximately $52 million higher than expected, with the increase comprised
of additional tax revenues ($22 million) and transfers from other funds ($30
million).  Total spending through the first six months of the fiscal year
was $16.28 billion, or $91 million lower than projected in July.  This
variance resulted primarily from higher spending in Grants to Local
Governments ($27 million), offset by lower spending in State Operations
($124 million).  These variances are timing-related and should not affect
total disbursements for the fiscal year.

Outyear Projections Of Receipts And Disbursements

     State law requires the Governor to propose a balanced budget each year.
In recent years, the State has closed projected budget gaps of $5.0 billion
(1995-96), $3.9 billion (1996-97), $2.3 billion (1997-98), and less than $1
billion (1998-99).  The State, as a part of the 1998-99 Executive Budget
projections submitted to the Legislature in February 1998, projected a 1999-
00 General Fund budget gap of approximately $1.7 billion and a 2000-01 gap
of $3.7 billion.  As a result of changes made in the 1998-99 enacted budget,
the 1999-00 gap is now expected to be roughly $1.3 billion, or about $400
million less than previously projected, after application of reserves
created as part of the 1998-99 budget process.  Such reserves would not be
available against subsequent year imbalances.

     Sustained growth in the State's economy could contribute to closing
projected budget gaps over the next several years, both in terms of higher-
than-projected tax receipts and in lower-than-expected entitlement spending.
However, the State's projections in 1999-00 currently assume actions to
achieve $600 million in lower disbursements and $250 million in additional
receipts from the settlement of State claims against the tobacco industry.
Consistent with past practice, the projections do not include any costs
associated with new collective bargaining agreements after the expiration of
the current round of contracts at the end of the 1998-99 fiscal year.  The
State expects that the 1999-00 Financial Plan will achieve savings from
initiatives by State agencies to deliver services more efficiently,
workforce management efforts, maximization of federal and non-General Fund
spending offsets, and other actions necessary to bring projected
disbursements and receipts into balance.

     The State will formally update its outyear projections of receipts and
disbursements for the 2000-01 and 2001-02 fiscal years as a part of the 1999-
00 Executive Budget process, as required by law.  The revised expectations
for years 2000-01 and 2001-02 will reflect the cumulative impact of tax
reductions and spending commitments enacted over the last several years as
well as new 1999-00 Executive Budget recommendations.  The STAR program,
which dedicates a portion of personal income tax receipts to fund school tax
reductions, has a significant impact on General Fund receipts.  STAR is
projected to reduce personal income tax revenues available to the General
Fund by an estimated $1.3 billion in 2000-01.  Measured from the 1998-99
base, scheduled reductions to estate and gift, sales and other taxes,
reflecting tax cuts enacted in 1997-98 and 1998-99, will lower General Fund
taxes and fees by an estimated $1.8 billion in 2000-01.  Disbursement
projections for the outyears currently assume additional outlays for school
aid, Medicaid, welfare reform, mental health community reinvestment, and
other multi-year spending commitments in law.  See "Special Considerations"
below for a description of other risks and uncertainties associated with the
State Financial Plan process.

Special Considerations

     The economic and financial condition of the State may be affected by
various financial, social, economic and political factors.  These factors
can be very complex, may vary from fiscal year to fiscal year, and are
frequently the result of actions taken not only by the State and its
agencies and instrumentalities, but also by entities, such as the federal
government, that are not under the control of the State.   Because of the
uncertainty and unpredictability of these factors, their impact cannot, as a
practical matter, be included in the assumptions underlying the State's
projections at this time.

     The State Financial Plan is based upon forecasts of national and State
economic activity developed through both internal analysis and review of
State and national economic forecasts prepared by commercial forecasting
services and other public and private forecasters.  Economic forecasts have
frequently failed to predict accurately the timing and magnitude of changes
in the national and the State economies.  Many uncertainties exist in
forecasts of both the national and State economies, including consumer
attitudes toward spending, the extent of corporate and governmental
restructuring, the condition of the financial sector, federal fiscal and
monetary policies, the level of interest rates, and the condition of the
world economy, which could have an adverse effect on the State.  There can
be no assurance that the State economy will not experience results in the
current fiscal year that are worse than predicted, with corresponding
material and adverse effects on the State's projections of receipts and
disbursements.

     Projections of total State receipts in the Financial Plan are based on
the State tax structure in effect during the fiscal year and on assumptions
relating to basic economic factors and their historical relationships to
State tax receipts.  In preparing projections of State receipts, economic
forecasts relating to personal income, wages, consumption, profits and
employment have been particularly important.  The projection of receipts
from most tax or revenue sources is generally made by estimating the change
in yield of such tax or revenue source caused by economic and other factors,
rather than by estimating the total yield of such tax or revenue source from
its estimated tax base.  The forecasting methodology, however, ensures that
State fiscal year collection estimates for taxes that are based on a
computation of annual liability, such as the business and personal income
taxes, are consistent with estimates of total liability under such taxes.

     Projections of total State disbursements are based on assumptions
relating to economic and demographic factors, levels of disbursements for
various services provided by local governments (where the cost is partially
reimbursed by the State), and the results of various administrative and
statutory mechanisms in controlling disbursements for State operations.
Factors that may affect the level of disbursements in the fiscal year
include uncertainties relating to the economy of the nation and the State,
the policies of the federal government, and changes in the demand for and
use of State services.

     An additional risk to the State Financial Plan arises from the
potential impact of certain litigation and of federal disallowances now
pending against the State, which could adversely affect the State's
projections of receipts and disbursements.  The State Financial Plan assumes
no significant litigation or federal disallowance or other federal actions
that could affect State finances, but has significant reserves in the event
of such an action.

     The Division of the Budget believes that its projections of receipts
and disbursements relating to the current State Financial Plan, and the
assumptions on which they are based, are reasonable.  Actual results,
however, could differ materially and adversely from the projections set
forth herein.  In the past, the State has taken management actions to
address potential Financial Plan shortfalls, and DOB believes it could take
similar actions should variances occur in its projections for the current
fiscal year.

     Despite recent budgetary surpluses recorded by the State, actions
affecting the level of receipts and disbursements, the relative strength of
the State and regional economy, and actions by the federal government have
helped to create projected structural budget gaps for the State.  These gaps
result from a significant disparity between recurring revenues and the costs
of maintaining or increasing the level of support for State programs.  To
address a potential imbalance in any given fiscal year, the State would be
required to take actions to increase receipts and/or or reduce disbursements
as it enacts the budget for that year, and, under the State Constitution,
the Governor is required to propose a balanced budget each year.  There can
be no assurance, however, that the Legislature will enact the Governor's
proposals or that the State's actions will be sufficient to preserve
budgetary balance in a given fiscal year or to align recurring receipts and
disbursements in future fiscal years.  For example, the fiscal effects of
tax reductions adopted in the last several fiscal years (including 1998-99)
are projected to grow more substantially beyond the 1998-99 fiscal year,
with the incremental annual cost of all currently enacted tax reductions
estimated at over $4 billion by the time they are fully effective in State
fiscal year 2002-03.  These actions will place pressure on future budget
balance in New York State.

1998-99 State Financial Plan

     Four governmental fund types comprise the State Financial Plan:  the
General Fund, the Special Revenue Funds, the Capital Projects Funds, and the
Debt Service Funds.

General Fund

     The General Fund is the principal operating fund of the State and is
used to account for all financial transactions except those required to be
accounted for in another fund.  It is the State's largest fund and receives
almost all State taxes and other resources not dedicated to particular
purposes.  In the State's 1998-99 fiscal year, the General Fund is expected
to account for approximately 47.6 percent of all Governmental Funds
disbursements and 70.1 percent of total State Funds disbursements.  General
Fund moneys are also transferred to other funds, primarily to support
certain capital projects and debt service payments in other fund types.
Total receipts and transfers from other funds are projected to be $37.56
billion, an increase of $3.01 billion from the 1997-98 fiscal year.  Total
General Fund disbursements and transfers to other funds are projected to be
$36.78 billion, an increase of $2.43 billion from the 1997-98 fiscal year.

Projected General Fund Receipts

     Total General Fund receipts in 1998-99 are projected to be $37.56
billion, an increase of over $3 billion from the $34.55 billion recorded in
1997-98.  This total includes $34.36 billion in tax receipts, $1.40 billion
in miscellaneous receipts, and $1.80 billion in transfers from other funds.

     The transfer of a portion of the surplus recorded in 1997-98 to 1998-99
exaggerates the "real" growth in State receipts from year to year by
depressing reported 1997-98 figures and inflating 1998-99 projections.
Conversely, the incremental cost of tax reductions newly effective in 1998-
99 and the impact of statutes earmarking certain tax receipts to other funds
work to depress apparent growth below the underlying growth in receipts
attributable to expansion of the State's economy.  On an adjusted basis,
State tax revenues in the 1998-99 fiscal year are projected to grow at
approximately 7.5 percent, following an adjusted growth of roughly nine
percent in the 1997-98 fiscal year.  The discussion below summarizes the
State's projections of General Fund taxes and other revenues for the 1998-99
Fiscal year.

     The Personal Income Tax is imposed on the income of individuals,
estates and trusts and is based with certain modifications on federal
definitions of income and deductions.  This tax continues to account for
over half of the State's General Fund receipts base.  Net personal income
tax collections are projected to reach $21.24 billion, nearly $3.5 billion
above the reported 1997-98 collection total.  Since 1997 represented the
completion of the 20 percent income tax reduction program enacted in 1995,
growth from 1997 to 1998 will be unaffected by major income tax reductions.
Adding to the projected annual growth is the net impact of the transfer of
the surplus from 1997-98 to the current year which affects reported
collections by over $2.4 billion on a year-over-year basis, as partially
offset by the diversion of slightly over $700 million in income tax receipts
to the STAR fund to finance the initial year of the school tax reduction
program.  The STAR program was enacted in 1997 to increase the State share
of school funding and reduce residential school taxes.  Adjusted for these
transactions, the growth in net income tax receipts is roughly $1.7 billion,
an increase of over 9 percent.  This growth is largely a function of over 8
percent growth in income tax liability projected for 1998 as well as the
impact of the 1997 tax year settlement on 1998-99 net collections.

     User taxes and fees are comprised of three-quarters of the State four
percent sales and use tax (the balance, one percent, flows to support Local
Government Assistance Corporation (LGAC) debt service requirements),
cigarette, alcoholic beverage, container, and auto rental taxes, and a
portion of the motor fuel excise levies.  Also included in this category are
receipts from the motor vehicle registration fees and alcoholic beverage
license fees.  A portion of the motor fuel tax and motor vehicle
registration fees and all of the highway use tax are earmarked for dedicated
transportation funds.

     Receipts from user taxes and fees are projected to total $7.14 billion,
an increase of $107 million from reported collections in the prior year.
The sales tax component of this category accounts for all of the 1998-99
growth, as receipts from all other sources decline $100 million.  The growth
in yield of the sales tax in 1998-99, after adjusting for tax law and other
changes, is projected at 4.7 percent.  The yields of most of the excise
taxes in this category show a long-term declining trend, particularly
cigarette and alcoholic beverage taxes.  These General Fund declines are
exacerbated in 1998-99 by revenue losses from scheduled and newly enacted
tax reductions, and by an increase in earmarking of motor vehicle
registration fees to the Dedicated Highway and Bridge Trust Fund.

     Business taxes include franchise taxes based generally on net income of
general business, bank and insurance corporations, as well as gross-receipts-
based taxes on utilities and gallonage-based petroleum business taxes.
Beginning in 1994, a 15 percent surcharge on these levies began to be phased
out and, for most taxpayers, there is no surcharge liability for taxable
periods ending in 1997 and thereafter.

     Total business tax collections in 1998-99 are now projected to be $4.96
billion, $91 million less than received in the prior fiscal year.  The
category includes receipts from the largely income-based levies on general
business corporations, banks and insurance companies, gross receipts taxes
on energy and telecommunication service providers and a per-gallon
imposition on petroleum business.  The year-over-year decline in projected
receipts in this category is largely attributable to statutory changes
between the two years.  These include the first year of utility-tax rate
cuts and the Power for Jobs tax reduction program for energy providers, and
the scheduled additional diversion of General Fund petroleum business and
utility tax receipts to other funds.  In addition, profit growth is also
expected to slow in 1998.

     Other taxes include estate, gift and real estate transfer taxes, a tax
on gains from the sale or transfer of certain real estate (this tax was
repealed in 1996), a pari-mutuel tax and other minor levies.  They are now
projected to total $1.02 billion -- $75 million below last year's amount.
Two factors account for a significant part of the expected decline in
collections from this category.  First, the effects of the elimination of
the real property gains tax collections; second, a decline in estate tax
receipts, following the explosive growth recorded in 1997-98, when receipts
expanded by over 16 percent.

     Miscellaneous receipts include investment income, abandoned property
receipts, medical provider assessments, minor federal grants, receipts from
public authorities, and certain other license and fee revenues.  Total
miscellaneous receipts are projected to reach $1.40 billion, down almost
$200 million from the prior year, reflecting the loss of non-recurring
receipts in 1997-98 and the growing effects of the phase-out of the medical
provider assessments.

     Transfers from other funds to the General Fund consist primarily of tax
revenues in excess of debt service requirements, particularly the one
percent sales tax used to support payments to LGAC.  Transfers from other
funds are expected to total $1.8 billion, or $222 million less than total
receipts from this category during 1997-98.  Total transfers of sales taxes
in excess of LGAC debt service requirements are expected to increase by
approximately $51 million, while transfers from all other funds are expected
to fall by $273 million, primarily reflecting the absence, in 1998-99, of a
one-time transfer of nearly $200 million for retroactive reimbursement of
certain social services claims from the federal government.

Projected General Fund Disbursements

     General Fund disbursements in 1998-99, including transfers to support
capital projects, debt service and other funds are estimated at $36.78
billion.  This represents an increase of $2.43 billion or 7.1 percent from
1997-98.  Nearly one-half of the growth is for educational purposes,
reflecting increased support for public schools, special education programs
and the State and City university systems.  The remaining increase is
primarily for Medicaid, mental hygiene, and other health and social welfare
programs, including children and family services.  The 1998-99 Financial
Plan also includes funds for the current negotiated salary increases for
State employees, as well as increased transfers for debt service.

     Grants to Local Governments is the largest category of General Fund
disbursements and includes financial assistance to local governments and not-
for-profit corporations, as well as entitlement benefits to individuals.
The 1998-99 Financial Plan projects spending of $25.14 billion in this
category, an increase of $1.88 billion or 8.1 percent over the prior year.
The largest annual increases are for educational programs, Medicaid, other
health and social welfare programs, and community projects grants.

     The 1998-99 budget provides $9.65 billion in support of public schools.
The year-to-year increase of $769 million is comprised of partial funding
for a 1998-99 school year increase of $847 million as well as the remainder
of the 1997-98 school year increase that occurs in State fiscal year 1998-
99.  Spending for all other educational programs, which includes the State
and City university systems, the Tuition Assistance Programs, and
handicapped programs, is estimated at $3.00 billion, an increase of $270
million over 1997-98 levels.

     Medicaid costs are estimated at $5.60 billion, an increase of $144
million from the prior year.  After adjusting 1997-98 for the $116 million
prepayment of an additional Medicaid cycle, Medicaid spending is projected
to increase $260 million or 4.9 percent.  Disbursements for all other health
and social welfare programs are projected to total $3.63 billion, an
increase of $131 million from 1997-98.  This includes an increase in support
for children and families and local public health programs, offset by a
decline in welfare spending of $75 million that reflects continuing State
and local efforts to reduce welfare fraud, declining caseloads, and the
impact of State and federal welfare reform legislation.

     Remaining disbursements primarily support community-based mental
hygiene programs, community and public health programs, local transportation
programs, and revenue sharing payments to local governments.  Revenue
sharing and other general purpose aid to local governments are projected at
$837 million, an increase of approximately $37 million from 1997-98.

     State operations spending reflects the administrative costs of
operating the State's agencies, including the prison system, mental hygiene
institutions, the State University system (SUNY), the Legislature, and the
court system.  Personal service costs account for approximately 73 percent
of spending in this category.  Since January 1995, the State's workforce has
been reduced by about 10 percent and is projected to remain at its current
level of approximately 191,000 persons in 1998-99.

     State operations spending is projected at $6.70 billion, an increase of
$511 million of 8.3 percent from the prior year.  This increase is primarily
due to an additional payroll cycle in 1998-99, a 3.5 percent general salary
increase on October 1, 1998 for most State employees, the loss of federal
receipts that would otherwise lower General Fund spending in mental hygiene
programs, and a projected 15.6 percent increase in the Judiciary's budget.

     General State charges account primarily for the costs of providing
fringe benefits for State employees, including contributions to pension
systems, the employer's share of social security contributions, employer
contributions toward the cost of health insurance, and the costs of
providing worker's compensation and unemployment insurance benefits.  This
category also reflects certain fixed costs such as payments in lieu of
taxes, and payments of judgments against the State or its public officers.

     Disbursements in this category are estimated at $2.22 billion, a
decrease of $50 million from the prior year.  This annual decline reflects
projected decreases in pension costs and Court of Claims payments, offset by
modest projected increases for health insurance contributions, social
security costs, and the loss of reimbursements due to a reduction in the
fringe benefit rate charged to positions financed by non-General Fund
sources.

     Debt service paid from the General Fund reflects debt service on short-
term obligations of the State, and includes only interest costs on the
State's commercial paper program.  The 1998-99 debt service estimate is $11
million, reflecting relative stability in short-term interest rates.  The
State's short-term TRAN borrowing program was eliminated in 1995.

     Transfers to other funds from the General Fund are made primarily to
finance certain portions of State capital projects spending and debt service
on long-term bonds where these costs are not funded from other sources.

     Transfers in support of debt service are projected at $2.13 billion in
1998-99, an increase of $110 million from 1997-98.  The increase reflects
the impact of certain prior year bond sales (net of refunding savings), and
certain bond sales planned to occur during the 1998-99 fiscal year.  The
State Financial Plan also establishes a transfer of $50 million to the new
Debt Reduction Reserve Fund.  The Fund may be used, subject to enactment of
new appropriations, to pay the debt service costs on or to prepay State-
supported bonds.

     Transfers in support of capital projects provide General Fund support
for projects not otherwise financed through bond proceeds, dedicated taxes
and other revenues, or federal grants.  These transfers are projected at
$200 million for 1998-99, comparable to last year.

     Remaining transfers from the General Fund to other funds are estimated
to decline $59 million in 1998-99 to $327 million.  This decline is
primarily the net impact of one-time transfers in 1997-98 to the State
University Tuition Stabilization Fund and to the Lottery Fund to support
school aid, offset by a 1998-99 increase in the State subsidy to the Roswell
Park Cancer Research Institute.

Non-recurring Resources

     The Division of the Budget estimates that the 1998-99 State Financial
Plan contains actions that provide non-recurring resources or savings
totaling approximately $64 million, the largest of which is a retroactive
reimbursement of federal welfare claims.

     The 1998-99 Financial Plan projects a closing fund balance in the
General Fund of $1.42 billion.  This fund balance is composed of a reserve
of $761 million available for future needs, a $400 million balance in the
TSRF, a $158 million balance in the CPF, and a balance of $100 million in
the CRF, after a projected deposit of $32 million in 1998-99.

Other Governmental Funds

     In addition to the General Fund, the State Financial Plan includes
Special Revenue Funds, Capital Projects Funds and Debt Service Funds which
are discussed below.  Amounts below do not include other sources and uses of
funds transferred to or from other fund types.

Special Revenue Funds

     Special Revenue Funds are used to account for the proceeds of specific
revenue sources such as federal grants that are legally restricted, either
by the Legislature or outside parties, to expenditures for specified
purposes.  Although activity in this fund type is expected to comprise
approximately 41 percent of total governmental funds receipts in the 1998-99
fiscal year, three-quarters of that activity relates to federally-funded
programs.

     Total disbursements for programs supported by Special Revenue Funds are
projected at $29.97 billion, an increase of $2.32 billion or 8.4 percent
from 1997-98.  Federal grants account for approximately three-quarters of
all spending in the Special Revenue fund type.  Disbursements from federal
funds are estimated at $21.78 billion, an increase of $1.12 billion or 5.4
percent.  The single largest program in this fund group is Medicaid, which
is projected at $13.65 billion, an increase of $465 million or 3.5 percent
above last year.  Federal support for welfare programs is projected at $2.53
billion, similar to 1997-98.  The remaining growth in federal funds is
primarily due to the new Child Health Plus program, estimated at $197
million in 1998-99.  This program will expand health insurance coverage to
children of indigent families.

     State special revenue spending is projected to be $8.19 billion, an
increase of $1.20 billion or 17.2 percent from last year's levels.  Most of
this projected increase in spending is due to the $704 million cost of the
first phase of the STAR program, as well as $231 million in additional
operating assistance for mass transportation, and $113 million for the State
share of the new Child Health Plus program.

Capital Projects Funds

     Capital Projects Funds account for the financial resources used in the
acquisition, construction, or rehabilitation of major State capital
facilities, and for capital assistance grants to certain local governments
or public authorities.  This fund type consists of the Capital Projects
Fund, which is supported by tax receipts transferred from the General Fund,
and various other capital funds established to distinguish specific capital
construction purposes supported by other revenues.  In the 1998-99 fiscal
year, activity in these funds is expected to comprise 5.5 percent of total
governmental receipts.

     Capital Projects Funds spending in fiscal year 1998-99 is projected at
$4.14 billion, an increase of $575 million or 16.1 percent from last year.
The major components of this expected growth are transportation and
environmental programs, including continued increased spending for 1996
Clean Water/Clean Air Bond Act projects and higher projected disbursements
from the Environmental Protection Fund (EPF).  Another significant component
of this projected increase is in the area of public protection, primarily
for facility rehabilitation and construction of additional prison capacity.

Debt Service Funds

     Debt Service Funds are used to account for the payment of principal and
interest on long-term debt of the State and to meet commitments under lease-
purchase and other contractual-obligation financing arrangements.  This fund
type is expected to comprise 3.8 percent of total governmental fund receipts
in the 1998-99 fiscal year.  Receipts in these funds in excess of debt
service requirements may be transferred to the General Fund, Capital
Projects Funds and Special Revenue Funds, pursuant to law.

     Total disbursements form the Debt Service Fund type are estimated at
$3.36 billion in 1998-99, an increase of $275 million or 8.9 percent from
1997-98 levels.  Of the increase, $102 million is for transportation
purposes, including debt service on bonds issued for State and local highway
and bridge programs financed through the New York State Thruway Authority
and supported by the Dedicated Highway and Bridge Trust Fund.  Another $45
million is for education purposes, including State and City University
programs financed through the Dormitory Authority of the State of New York
(DASNY).  The remainder is for a variety of programs in such areas as mental
health and corrections, and for general obligation financings.

Year 2000 Compliance

     New York State is currently addressing "Year 2000" data processing
compliance issues.  The Year 2000 compliance issue ("Y2K") arises because
most computer software programs allocate two digits to the data field for
"year" on the assumption that the first two digits will be "19."  Such
programs will thus interpret the year 2000 as the year 1900 absent
reprogramming.  Y2K could impact both the ability to enter data into
computer programs and the ability of such programs to correctly process
data.

     In 1996, the State created the Office for Technology (OFT) to help
address statewide technology issues, including the Year 2000 issue.  OFT has
estimated that investments of at least $140 million will be required to
bring approximately 350 State mission-critical and high-priority computer
systems not otherwise scheduled for replacement into Year 2000 compliance,
and the State is planning to spend $100 million in the 1998-99 fiscal year
for this purpose.  Mission-critical computer applications are those which
impact the health, safety and welfare of the State and its citizens, and for
which failure to be in Y2K compliance could have a material and adverse
impact upon State operations.  High-priority computer applications are those
that are critical for a State agency to fulfill its mission and deliver
services, but for which they are manual alternatives.  Work has been
completed on roughly 20 percent of these systems.  All remaining unfinished
mission-critical and high-priority systems have at least 40 percent or more
of the work completed.  Contingency planning is underway for those systems
which may be non-compliant prior to failure dates.  The enacted budget also
continues funding for major systems scheduled for replacement, including the
State payroll, civil service, tax and finance and welfare management
systems, for which Year 2000 compliance is included as a part of the
project.

     OFT is monitoring compliance on a quarterly basis and is providing
assistance and assigning resources to accelerate compliance for mission-
critical systems, with most compliance testing expected to be completed by
mid-1999.  There can be no guarantee, however, that all of the State's
mission-critical and high-priority computer systems will be Year 2000
compliant and that there will not be an adverse impact upon State operations
or State finances as a result.

Cash-Basis Results for Prior Fiscal Years

     The State reports its financial results on two bases of accounting: the
cash basis, showing receipts and disbursements; and the modified accrual
basis, prescribed by Generally Accepted Accounting Principles ("GAAP"),
showing revenues and expenditures.

General Fund 1995-96 through 1997-98

     The General Fund is the principal operating fund of the State and is
used to account for all financial transactions, except those required to be
accounted for in another fund.  It is the State's largest fund and receives
most State taxes and other resources not dedicated to particular purposes.
General Fund moneys are also transferred to other funds, primarily to
support certain capital projects and debt service payments in other fund
types.  A narrative description of cash-basis results in the General Fund is
presented below.

     New York State's financial operations have improved during recent
fiscal years.  During the period 1989-90 through 1991-92, the State incurred
General Fund operating deficits that were closed with receipts from the
issuance of tax and revenue anticipation notes TRANs.  A national recession,
followed by the lingering economic slowdown in New York and the regional
economy, resulted in repeated shortfalls in receipts and three budget
deficits during those years.  During its last six fiscal years, however, the
State has recorded balanced budgets on a cash basis, with positive fund
balances as described below.

1997-98 Fiscal Year

     The State ended its 1997-98 fiscal year in balance on a cash basis,
with a General Fund cash surplus as reported by DOB of approximately $2.04
billion.  The cash surplus was derived primarily from higher-than-
anticipated receipts and lower spending on welfare, Medicaid, and other
entitlement programs.

     The General Fund had a closing balance of $638 million, an increase of
$205 million from the prior fiscal year.  The balance is held in three
accounts within the General Fund:  the Tax Stabilization Reserve Fund
(TSRF), the Contingency Reserve Fund (CRF) and the Community Projects Fund
(CPF).  The TSRF closing balance was $400 million, following a required
deposit of $15 million (repaying a transfer made in 1991-92) and an
extraordinary deposit of $68 million made from the 1997-98 surplus.  The CRF
closing balance was $68 million, following a $27 million deposit from the
surplus.  The CPF, which finances legislative initiatives, closed the fiscal
year with a balance of $170 million, an increase of $95 million.  The
General Fund closing balance did not include $2.39 billion in the tax refund
reserve account, of which $521 million was made available as a result of the
Local Government Assistance Corporation (LGAC) financing program and was
required to be on deposit on March 31, 1998.

     General Fund receipts and transfers from other funds for the 1997-98
fiscal year (including net tax refund reserve account activity) totaled
$34.55 billion, an annual increase of $1.51 billion, or 4.57 percent over
1996-97.  General Fund disbursements and transfers to other funds were
$34.35 billion, an annual increase of $1.45 billion or 4.41 percent.

1996-97 Fiscal Year

     The State ended its 1996-97 fiscal year on March 31, 1997 in balance on
a cash basis, with a General Fund cash surplus as reported by DOB of
approximately $1.42 billion.  The cash surplus was derived primarily from
higher-than-expected receipts and lower-than-expected spending for social
services programs.

     The General Fund closing balance was $433 million, an increase of $146
million from the 1995-96 fiscal year.  The balance included $317 million in
the TSRF, after a required deposit of $15 million and an additional deposit
of $65 million in 1996-97.  In addition, $41 million remained on deposit in
the CRF.  The remaining $75 million reflected amounts then on deposit in the
Community Projects Fund.  The General Fund closing balance did not include
$1.86 billion in the tax refund reserve account, of which $521 million was
made available as a result of the LGAC financing program and was required to
be on deposit as of March 31, 1997.

     General Fund receipts and transfers from other funds for the 1996-97
fiscal year totaled $33.04 billion, an increase of 0.7 percent from the
previous fiscal year (including net tax refund reserve account activity).
General Fund disbursements and transfers to other funds totaled $32.90
billion for the 1996-97 fiscal year, an increase of 0.7 percent from the
1995-96 fiscal year.

1995-96 Fiscal Year

     The State ended its 1995-96 fiscal year on March 31, 1996 with a
General Fund cash surplus, as reported by DOB, of $445 million.  The cash
surplus was derived from higher-than-expected receipts, savings generated
through agency cost controls, and lower-than-expected welfare spending.

     The General Fund closing fund balance was $287 million, an increase of
$129 million from 1994-95 levels.  The $129 million change in fund balance
is attributable to a $65 million voluntary deposit to the TSRF, a $15
million required deposit to the TSRF, a $40 million deposit to the CRF, and
a $9 million deposit to the Revenue Accumulation Fund.  The closing fund
balance included $237 million on deposit in the TSRF.  In addition, $41
million was on deposit in the CRF.  The remaining $9 million reflected
amounts then on deposit in the Revenue Accumulation Fund.  The General Fund
closing balance did not include $678 million in the tax refund reserve
account of which $521 million was made available as a result of the LGAC
financing program and was required to be on deposit as of March 31, 1996.

     General Fund receipts and transfers from other funds (including net
refund reserve account activity) totaled $32.81 billion, a decrease of 1.1
percent from 1994-95 levels.  General Fund disbursements and transfers to
other funds totaled $32.68 billion for the 1995-96 fiscal year, a decrease
of 2.2 percent from 1994-95 levels.

Other Governmental Funds (1995-96 through 1997-98)

     Activity in the three other governmental funds has remained relatively
stable over the last three fiscal years, with federally-funded programs
comprising approximately two-thirds of these funds.  The most significant
change in the structure of these funds has been the redirection of a portion
of transportation-related revenues from the General Fund to two new
dedicated funds in the Special Revenue and Capital Projects fund types.
These revenues are used to support the capital programs of the Department of
Transportation and the Metropolitan Transportation Authority (MTA).

     In the Special Revenue Funds, disbursements increased from $26.26
billion to $27.65 billion over the last three years, primarily as a result
of increased costs for the federal share of Medicaid.  Other activity
reflected dedication of taxes to a new fund for mass transportation, new
lottery games, and new fees for criminal justice programs.

     Disbursements in the Capital Projects Funds declined over the three
year period from $3.97 billion to $3.56 billion as spending for
miscellaneous capital programs decreased, partially offset by increases for
mental hygiene, health and environmental programs.  The composition of this
fund type's receipts also changed as the dedicated transportation taxes
began to be deposited, general obligation bond proceeds declined
substantially, federal grants remained stable, and reimbursements from
public authority bonds (primarily transportation related) increased.

     Activity in the Debt Service Funds reflected increased use of bonds
during the three-year period for improvements to the State's capital
facilities and the continued costs of the LGAC fiscal reform program.  The
increases were moderated by the refunding savings achieved by the State over
the last several years using strict present value savings criteria.  The
growth in LGAC debt service was offset by reduced short-term borrowing costs
reflected in the General Fund.

Litigation
State Finance Policies

Insurance Law

     Proceedings have been brought by two groups of petitioners challenging
regulations promulgated by the Superintendent of Insurance that established
excess medical malpractice premium rates for fiscal years 1986-87 through
1996-97 (New York State Health Maintenance Organization Conference, Inc., et
al. v. Muhl, et al. ["HMO"], and New York State Conference of Blue Cross and
Blue Shield Plans, et al. v. Muhl, et al.  ["Blue Cross 'I' and 'II'"],
Supreme Court, Albany County).  By order filed January 22, 1997, the Court
in Blue Cross I permitted the plaintiffs in HMO to intervene and dismissed
the challenges to the rates for the period prior to 1995-96.  By decision
dated July 24, 1997, the Court in Blue Cross I held that the determination
made by the Superintendent in establishing the 1995-96 rate was arbitrary
and capricious and directed that premiums paid pursuant to that
determination be returned to the payors.  The State has appealed this
decision.  The petitioners did not cross appeal. In Blue Cross II, by
amended judgment dated April 2, 1998, the Supreme Court annulled the
regulation setting the 1996-97 premium rate and directed that all 1996-97
excess malpractice premiums be returned to the payors.  The State will not
be obligated in either case to pay moneys to any petitioner.  Adverse
determinations would result in refunds from the affected insurers.

Tax Law

     In New York Association of Convenience Stores, et al. v. Urbach, et
al., petitioners, New York Association of Convenience Stores, National
Association of Convenience Stores, M.W.S. Enterprises, Inc. and Sugarcreek
Stores, Inc. seek to compel respondents, the Commissioner of Taxation and
Finance and the Department of Taxation and Finance, to enforce sales and
excise taxes imposed pursuant to Tax Law Articles 12-A, 20 and 28 on tobacco
products and motor fuel sold to non-Indian consumers on Indian reservations.
In orders dated August 13, 1996 and August 24, 1996, the Supreme Court,
Albany County, ordered, inter alia, that there be equal implementation and
enforcement of said taxes for sales to non-Indian consumers on and off
Indian reservations, and further ordered that, if respondents failed to
comply within 120 days, no tobacco products or motor fuel could be
introduced onto Indian reservations other than for Indian consumption or,
alternately, the collection and enforcement of such taxes would be suspended
statewide.  Respondents appealed to the Appellate Division, Third
Department, and invoked CPLR 5519(a)(1), which provides that the taking of
the appeal stayed all proceedings to enforce the orders pending the appeal.
Petitioner's motion to vacate the stay was denied.  In a decision entered
May 8, 1997, the Third Department modified the orders by deleting the
portion thereof that provided for the statewide suspension of the
enforcement and collection of the sales and excise taxes on motor fuel and
tobacco products.  The Third Department held, inter alia, that petitioners
had not sought such relief in their petition and that it was an error for
the Supreme Court to have awarded such undemanded relief without adequate
notice of its intent to do so.  On May 22, 1997, respondents appealed to the
Court of Appeals on other grounds, and again invoked the statutory stay.  On
October 23, 1997, the Court of Appeals granted petitioners' motion for leave
to cross-appeal from the portion of the Third Department's decision that
deleted the statewide suspension of the enforcement and collection of the
sales and excise taxes on motor fuel and tobacco.  The case was argued
before the Court of Appeals on March 24, 1998.

Clean Water/Clean Air Bond Act of 1996

     In Robert L. Schulz, et al. v. The New York State Executive, et al.
(Supreme Court, Albany County, commenced October 16, 1996), plaintiffs
challenge the enactment of the Clean Water/Clean Air Bond Act of 1996 and
its implementing legislation (1996 Laws of New York, Chapters 412 and 413).
Plaintiffs claim, inter alia, that the Bond Act and its implementing
legislation violate provisions of the State Constitution requiring that such
debt be authorized by law for some single work or purpose distinctly
specified therein and forbidding incorporation of other statutes by
reference.

     In an opinion dated June 9, 1998, the Court of Appeals affirmed the
July 17, 1997 order of the Appellate Division, Third Department, affirming
the lower court dismissal of this case.

Line Item Veto

     In an action commenced in June 1998 by the Speaker of the Assembly of
the State of New York against the Governor of the State of New York (Silver
v. Pataki, Supreme Court, New York County), the Speaker challenges the
Governor's application of his constitutional line item veto authority to
certain portions of budget bills adopted by the State Legislature contained
in Chapters 56, 57 and 58 of the Laws of 1998.

State Programs

Medicaid

     Several cases challenge provisions of Chapter 81 of the Laws of 1995
which alter the nursing home Medicaid reimbursement methodology on and after
April 1, 1995.  Included are New York State Health Facilities Association,
et al. v. DeBuono, et al., St. Luke's Nursing Center, et al. v. DeBuono, et
al., New York Association of Homes and Services for the Aging v DeBuono et
al (three cases), Healthcare Association of New York State v. DeBuono and
Bayberry Nursing Home et al. v. Pataki, et al. Plaintiffs allege that the
changes in methodology have been adopted in violation of procedural and
substantive requirements of State and federal law.

     In a consolidated action commenced in 1992, Medicaid recipients and
home health care providers and organizations challenge promulgation by the
State Department of Social Services (DSS) in June 1992 of a home assessment
resource review instrument (HARRI), which is to be used by DSS to determine
eligibility for and the nature of home care services for Medicaid
recipients, and challenge the policy of DSS of limiting reimbursable hours
of service until a patient is assessed using the HARRI (Dowd, et al. v.
Bane, Supreme Court, New York County).

     In several cases, plaintiffs seek retroactive claims for reimbursement
for services provided to Medicaid recipients who were also eligible for
Medicare during the period January 1, 1987 to June 2, 1992.  Included are
Matter of New York State Radiological Society v. Wing, Appel v. Wing, E.F.S.
Medical Supplies v. Dowling, Kellogg v. Wing, Lifshitz v. Wing, New York
State Podiatric Medical Association v. Wing and New York State Psychiatric
Association v. Wing.  These cases were commenced after the State's
reimbursement methodology was held invalid in New York City Health and
Hospital Corp. v. Perales.  The State contends that these claims are
time-barred.  In a judgment dated September 5, 1996, the Supreme Court,
Albany County, dismissed Matter of New York State Radiological Society v.
Wing as time-barred.  By order dated November 26, 1997, the Appellate
Division, Third Department, affirmed that judgment.  By decision dated June
9, 1998, the Court of Appeals denied leave to appeal.

     Several cases, including Port Jefferson Health Care Facility, et al. v.
Wing (Supreme Court, Suffolk County), challenge the constitutionality of
Public Health Law  2807-d, which imposes a tax on the gross receipts
hospitals and residential health care facilities receive from all patient
care services.  Plaintiffs allege that the tax assessments were not
uniformly applied, in violation of federal regulations.  In a decision dated
June 30, 1997, the Court held that the 1.2 percent and 3.8 percent
assessments on gross receipts imposed pursuant to Public Health Law
2807-d(2)(b)(ii) and 2807-d(2)(b)(iii), respectively, are unconstitutional.
An order entered August 27, 1997 enforced the terms of the decision.  The
State has appealed that order.

Shelter Allowance

     In an action commenced in March 1987 against State and New York City
officials (Jiggetts, et al. v. Bane, et al., Supreme Court, New York
County), plaintiffs allege that the shelter allowance granted to recipients
of public assistance is not adequate for proper housing.  In a decision
dated April 16, 1997, the Court held that the shelter allowance promulgated
by the Legislature and enforced through DSS regulations is not reasonably
related to the cost of rental housing in New York City and results in
homelessness to families in New York City.  A judgment was entered on July
25, 1997, directing, inter alia, that the State (i) submit a proposed
schedule of shelter allowances (for the Aid to Dependent Children program
and any successor program) that bears a reasonable relation to the cost of
housing in New York City; and (ii) compel the New York City Department of
Social Services to pay plaintiffs a monthly shelter allowance in the full
amount of their contract rents, provided they continue to meet the
eligibility requirements for public assistance, until such time as a lawful
shelter allowance is implemented, and provide interim relief to other
eligible recipients of Aid to Dependent Children under the interim relief
system established in this case.  The State has appealed to the Appellate
Division, First Department from each and every provision of this judgment
except that portion directing the continued provision of interim relief.

Civil Rights Claims

     In an action commenced in 1980 (United States, et al. v. Yonkers Board
of Education, et al.), the United States District Court for the Southern
District of New York found, in 1985, that Yonkers and its public schools
were intentionally segregated.  In 1986, the District Court ordered Yonkers
to develop and comply with a remedial educational improvement plan (EIP I).
On January 19, 1989, the District Court granted motions by Yonkers and the
NAACP to add the State Education Department, the Yonkers Board of Education,
and the State Urban Development Corporation as defendants, based on
allegations that they had participated in the perpetuation of the segregated
school system.  On August 30, 1993, the District Court found that vestiges
of a dual school system continued to exist in Yonkers.  On March 27, 1995,
the District Court made factual findings regarding the role of the State and
the other State defendants (the State) in connection with the creation and
maintenance of the dual school system, but found no legal basis for imposing
liability.  On September 3, 1996, the United States Court of Appeals for the
Second Circuit, based on the District Court's factual findings, held the
State defendants liable under 42 USC  1983 and the Equal Educational
Opportunity Act, 20 USC  1701, et seq., for the unlawful dual school
system, because the State, inter alia, had taken no action to force the
school district to desegregate despite its actual or constructive knowledge
of de jure segregation.  By order dated October 8, 1997, the District Court
held that vestiges of the prior segregated school system continued to exist
and that, based on the State's conduct in creating and maintaining that
system, the State is liable for eliminating segregation and its vestiges in
Yonkers and must fund a remedy to accomplish that goal.  Yonkers presented a
proposed educational improvement plan (EIP II) to eradicate these vestiges
of segregation.  The October 8, 1997 order of the District Court ordered
that EIP II be implemented and directed that, within 10 days of the entry of
the Order, the State make available to Yonkers $450,000 to support planning
activities to prepare the EIP II budget for 1997-98 and the accompanying
capital facilities plan.  A final judgment to implement EIP II was entered
on October 14, 1997.  On November 7, 1997, the State appealed that judgment
to the Second Circuit.  The appeal is pending.  Additionally, the Court
adopted a requirement that the State pay to Yonkers approximately $9.85
million as its pro rata share of the funding of EIP I for the 1996-97 school
year.  The requirement for State funding of EIP I was reduced to an order on
December 2, 1997 and reduced to a judgment on February 10, 1998.  The State
appealed that order to the Second Circuit on December 31, 1997 and amended
the notice of appeal after entry of the judgment.  That appeal has been
consolidated with the appeal of the EIP II appeal, and is also pending.

         On June 15, 1998, the District Court issued an opinion setting
forth the formula for the allocation of the costs of EIP I and EIP II
between the State and the City for the school years 1997-98 through 2005-06.
That opinion has not yet been reduced to an order.

Real Property Claims

         On March 4, 1985 in Oneida Indian Nation of New York, et al. v.
County of Oneida, the United States Supreme Court affirmed a judgment of the
United States Court of Appeals for the Second Circuit holding that the
Oneida Indians have a common-law right of action against Madison and Oneida
Counties for wrongful possession of 872 acres of land illegally sold to the
State in 1795.  At the same time, however, the Court reversed the Second
Circuit by holding that a third-party claim by the counties against the
State for indemnification was not properly before the federal courts.  The
case was remanded to the District Court for an assessment of damages, which
action is still pending.  The counties may still seek indemnification in the
State courts.

         Several other actions involving Indian claims to land in upstate
New York are also pending.  Included are Cayuga Indian Nation of New York v.
Cuomo, et al., and Canadian St. Regis Band of Mohawk Indians, et al. v.
State of New York et al., both in the United States District Court for the
Northern District of New York.  The Supreme Court's holding in Oneida Indian
Nation of New York may impair or eliminate certain of the State's defenses
to these actions but may enhance others.

Authorities and Localities

Public Authorities

     The fiscal stability of the State is related in part to the fiscal
stability of its public authorities.  For the purposes of this summary,
public authorities refer to public benefit corporations created pursuant to
State law, other than local authorities.  Public authorities are not subject
to the constitutional restrictions on the incurrence of debt which apply to
the State itself and may issue bonds and notes within the amounts and
restrictions set forth in legislative authorization.  The State's access to
the public credit markets could be impaired and the market price of its
outstanding debt may be materially and adversely affected if any of its
public authorities were to default on their respective obligations.  As of
December 31, 1997, there were 17 public authorities that had outstanding
debt of $100 million or more, and the aggregate outstanding debt, including
refunding bonds, of all State authorities was $84 billion, only a portion of
which constitutes State-supported or State-related debt.

     The State has numerous public authorities with various
responsibilities, including those which finance, construct and/or operate
revenue producing public facilities.  Public authorities generally pay their
operating expenses and debt service costs from revenues generated by the
projects they finance or operate, such as tolls charged for the use of
highways, bridges or tunnels, charges for public power, electric and gas
utility services, rentals charged for housing units, and charges for
occupancy at medical care facilities.  Also, there are statutory
arrangements providing for State local assistance payments otherwise payable
to localities to be made under certain circumstances to public authorities.
Although the State has no obligation to provide additional assistance to
localities whose local assistance payments have been paid to public
authorities under these arrangements, the affected localities may seek
additional State assistance if local assistance payments are diverted. Some
authorities also receive moneys from State appropriations to pay for the
operating costs of certain of their programs.  As described below, the MTA
receives the bulk of this money in order to provide transit and commuter
services.

     Beginning in 1998, the Long Island Power Authority (LIPA) assumed
responsibility for the provision of electric utility services previously
provided by Long Island Lighting Company for Nassau, Suffolk and a portion
of Queen Counties, as part of an estimated $7 billion financing plan.  As of
the date of this AIS, LIPA has issued over $5 billion in bonds secured
solely by ratepayer charges.  LIPA's debt is not considered either State-
supported or State-related debt.

Metropolitan Transportation Authority

     The MTA oversees the operation of subway and bus lines in New York City
by its affiliates, the New York City Transit Authority and the Manhattan and
Bronx Surface Transit Operating Authority (collectively, the "TA").  The MTA
operates certain commuter rail and bus services in the New York Metropolitan
area through MTA's subsidiaries, the Long Island Rail Road Company, the
Metro-North Commuter Railroad Company, and the Metropolitan Suburban Bus
Authority.  In addition, the Staten Island Rapid Transit Operating
Authority, an MTA subsidiary, operates a rapid transit line on Staten
Island.  Through its affiliated agency, the Triborough Bridge and Tunnel
Authority (the "TBTA"), the MTA operates certain intrastate toll bridges and
tunnels.  Because fare revenues are not sufficient to finance the mass
transit portion of these operations, the MTA has depended on, and will
continue to depend on, operating support from the State, local governments
and TBTA, including loans, grants and subsidies.  If current revenue
projections are not realized and/or operating expenses exceed current
projections, the TA or commuter railroads may be required to seek additional
State assistance, raise fares or take other actions.

     Since 1980, the State has enacted several taxes-including a surcharge
on the profits of banks, insurance corporations and general business
corporations doing business in the 12-county Metropolitan Transportation
Region served by the MTA and a special one-quarter of 1 percent regional
sales and use tax--that provide revenues for mass transit purposes,
including assistance to the MTA.  Since 1987, State law also has required
that the proceeds of a one-quarter of 1 percent mortgage recording tax paid
on certain mortgages in the Metropolitan Transportation Region be deposited
in a special MTA fund for operating or capital expenses.  In 1993, the State
dedicated a portion of certain additional State petroleum business tax
receipts to fund operating or capital assistance to the MTA.  For the 1998-
99 fiscal year, State assistance to the MTA is projected to total
approximately $1.3 billion, an increase of $133 million over the 1997-98
fiscal year.

     State legislation accompanying the 1996-97 adopted State budget
authorized the MTA, TBTA and TA to issue an aggregate of $6.5 billion in
bonds to finance a portion of the $12.17 billion MTA capital plan for the
1995 through 1999 calendar years (the "1995-99 Capital Program"). In July
1997, the Capital Program Review Board ("CPRB") approved the 1995-99 Capital
Program (subsequently amended in August 1997), which supersedes the
overlapping portion of the MTA's 1992-96 Capital Program.  The 1995-99
Capital Program is the fourth capital plan since the Legislature authorized
procedures for the adoption, approval and amendment of MTA capital programs
and is designed to upgrade the performance of the MTA's transportation
systems by investing in new rolling stock, maintaining replacement schedules
for existing assets and bringing the MTA system into a state of good repair.
The 1995-99 Capital Program assumes the issuance of an estimated $5.2
billion in bonds under this $6.5 billion aggregate bonding authority. The
remainder of the plan is projected to be financed through assistance from
the State, the federal government, and the City of New York, and from
various other revenues generated from actions taken by the MTA.

     There can be no assurance that all the necessary governmental actions
for future capital programs will be taken, that funding sources currently
identified will not be decreased or eliminated, or that the 1995-99 Capital
Program, or parts thereof, will not be delayed or reduced.  Should funding
levels fall below current projections, the MTA would have to revise its 1995-
99 Capital Program accordingly.  If the 1995-99 Capital Program is delayed
or reduced, ridership and fare revenues may decline, which could, among
other things, impair the MTA's ability to meet its operating expenses
without additional assistance.

The City of New York

     The fiscal health of the State may also be affected by the fiscal
health of New York City (the "City"), which continues to receive significant
financial assistance from the State.  State aid contributes to the City's
ability to balance its budget and to meet its cash requirements.  The State
may also be affected by the ability of the City and certain entities issuing
debt for the benefit of the City to market their securities successfully in
the public credit markets.

     The City has achieved balanced operating results for each of its fiscal
years since 1981 as measured by the GAAP standards in force at that time.
The City prepares a four-year financial plan ("Financial Plan") annually and
updates it periodically, and prepares a comprehensive annual financial
report describing its most recent fiscal year each October.

The City of New York
Fiscal Oversight

     In response to the City's fiscal crisis in 1975, the State took action
to assist the City in returning to fiscal stability.  Among those actions,
the State established the Municipal Assistance Corporation for the City of
New York to provide financing assistance to the City; the New York State
Financial Control Board (the "Control Board") to oversee the City's
financial affairs; and the Office of the State Deputy Comptroller for the
City of New York ("OSDC") to assist the Control Board in exercising its
powers and responsibilities.  A "control period" existed from 1975 to 1986
during which the City was subject to certain statutorily-prescribed fiscal
controls.  The Control Board terminated the Control Period in 1986 when
certain statutory conditions were met.  State law requires the Control Board
to reimpose a control period upon the occurrence, or "substantial likelihood
and imminence" of the occurrence, of certain events, including (but not
limited to) a City operating budget deficit of more than $100 million of
impaired access to the public credit markets.

     Currently, the City and its Covered Organizations (i.e., those which
received or may receive moneys from the City directly, indirectly or
contingently) operate under the Financial Plan.  The City's Financial Plan
summarizes its capital, revenue and expense projections and outlines
proposed gap-closing programs for years with projected budget gaps.  The
City's projections set forth in the Financial Plan are based on various
assumptions and contingencies, some of which are uncertain and may not
materialize.  Unforeseen developments and changes in major assumptions could
significantly affect the city's ability to balance its budget as required by
State law and to meet its annual cash flow and financing requirements.

     To successfully implement its Financial Plan, the City and certain
entities issuing debt for the benefit of the city must market their
securities successfully.  The City issues securities to finance, refinance
and rehabilitate infrastructure and other capital needs, as well as for
seasonal financing needs.  In 1997, the State created the New York City
Transitional Finance Authority ("TFA") to finance a portion of the City's
capital program because the City was approaching its State Constitutional
general debt limit.  Without the additional financing capacity of the TFA,
projected contracts for City capital projects would have exceeded the City's
debt limit during City fiscal year 1997-98.  Despite this additional
financing mechanism, the City currently projects that, if no further action
is taken, it will reach its debt limit in City fiscal year 1999-2000.  On
June 2, 1997, an action was commenced seeking a declaratory judgment
declaring the legislation establishing the TFA to be unconstitutional.  On
November 25, 1997 the State Supreme Court found the legislation establishing
the TFA to be constitutional and granted the defendants' motion for summary
judgment.  The plaintiffs have appealed the decision.  Future developments
concerning the City or entities  issuing debt for the benefit of the City,
and public discussion of such developments, as well as prevailing market
conditions and securities credit ratings, may affect the ability or cost to
sell securities issued by the City or such entities and may also affect the
market for their outstanding securities.

Monitoring Agencies

     The staffs of the Control Board, OSDC and the City Comptroller issue
periodic reports on the City's Financial Plans.  The reports analyze the
City's forecasts of revenues and expenditures, cash flow, and debt service
requirements, as well as evaluate compliance by the City and its Covered
Organizations with the Financial Plan.  According to recent staff reports,
while economic growth in New York City has been slower than in other regions
of the country, a surge in Wall Street profitability resulted in increased
tax revenues and generated a substantial surplus for the City in City fiscal
year 1996-97.  Recent staff reports also indicate that the City projects a
substantial surplus for City fiscal year 1997-98.  Although several sectors
of the City's economy have expanded recently, especially tourism and
business and professional services, City tax revenues remain heavily
dependent on the continued profitability of the securities industries and
the course of the national economy.  These reports have also indicated that
recent City budgets have been balanced in part through the use of non-
recurring resources and that the City's Financial Plan tends to rely on
actions outside its direct control.  These reports have indicated that the
City has not yet brought its long-term expenditure growth in line with
recurring revenue growth and that the City is likely to continue to face
substantial gaps between forecast revenues and expenditures in future years
that must be closed with reduced expenditures and/or increased revenues.  In
addition to these monitoring agencies, the Independent Budget Office ("IBO")
has been established pursuant to the City Charter to provide analysis to
elected officials and the public on relevant fiscal and budgetary issues
affecting the City.

Other Localities

     Certain localities outside New York City have experienced financial
problems and have requested and received additional State assistance during
the last several State fiscal years.  The cities of Yonkers and Troy
continue to operate under State-ordered control agencies.  The potential
impact on the State of any future requests by localities for additional
oversight or financial assistance is not included in the projections of the
State's receipts and disbursements for the State's 1998-99 fiscal year.

     Eighteen municipalities received extraordinary assistance during the
1996 legislative session through $50 million in special appropriations
targeted for distressed cities, and twenty-eight municipalities received
more than $32 million in targeted unrestricted aid in the 1997-98 budget.
Both of these emergency aid packages were largely continued through the 1998-
99 budget.  The State also dispersed an additional $21 million among all
cities, towns and villages after enacting a 3.9 percent increase in General
Purpose State Aid in 1997-98 and continued this increase in 1998-99.

     The 1998-99 budget includes an additional $29.4 million in unrestricted
aid targeted to 57 municipalities across the State.  Other assistance for
municipalities with special needs totals more than $25.6 million.  Twelve
upstate cities will receive $24.2 million in one-time assistance from a cash
flow acceleration of State aid.

     The appropriation and allocation of general purpose local government
aid among localities, including New York City, is currently the subject of
investigation by a State commission.  While the distribution of general
purpose local government aid was originally based on a statutory formula, in
recent years both the total amount appropriated and the amounts appropriated
to localities have been determined by the Legislature.  A State commission
was established to study the distribution and amounts of general purpose
local government aid and recommend a new formula by June 30, 1999, which may
change the way aid is allocated.

     Municipalities and school districts have engaged in substantial short-
term and long-term borrowings.  In 1996, the total indebtedness of all
localities in the State other than New York City was approximately $20.0
billion.  A small portion (approximately $77.2 million) of that indebtedness
represented borrowing to finance budgetary deficits and was issued pursuant
to State enabling legislation.  State law requires the Comptroller to review
and make recommendations concerning the budgets of those local government
units other than New York City that are authorized by State law to issue
debt to finance deficits during the period that such deficit financing is
outstanding.  Twenty-one localities had outstanding indebtedness for deficit
financing at the close of their fiscal year ending in 1996.

     Like the State, local governments must respond to changing political,
economic and financial influences over which they have little or no control.
Such changes may adversely affect the financial condition of certain local
governments.  For example, the federal government may reduce (or in some
cases eliminate) federal funding of some local programs which, in turn, may
require local governments to fund these expenditures from their own
resources.  It is also possible that the State, New York City, or any of
their respective public authorities may suffer serious financial
difficulties that could jeopardize local access to the public credit
markets, which may adversely affect the marketability of notes and bonds
issued by localities within the State.  Localities may also face
unanticipated problems resulting from certain pending litigation, judicial
decisions and long-range economic trends.  Other large-scale potential
problems, such as declining urban populations, increasing expenditures, and
the loss of skilled manufacturing jobs, may also adversely affect localities
and necessitate State assistance.

Item 24.  Persons Controlled by or under Common Control with Registrant

          Not Applicable


Item 25.   Indemnification

        Reference is made to Article EIGHT of the Registrant's Articles of
        Incorporation previously filed as Exhibit 1 of Post-Effective Amendment
        No.  9 to the Registration Statement on Form N-1A, filed on January 26,
        1994.  The application of these provisions is limited by Article 10 of
        the Registrant's By-Laws previously filed as Exhibit 2 to Post-Effective
        Amendment No. 11 to the Registration Statement on Form N-1A on October
        25, 1995 and by the following undertaking set forth in the rules
        promulgated by the Securities and Exchange Commission:  Insofar as
        indemnification for liabilities arising under the Securities Act
        of 1933 may be permitted to trustees, officers and controlling
        persons of the registrant pursuant to the foregoing provisions,
        or otherwise, the registrant has been advised that in the opinion
        of the Securities and Exchange Commission such indemnification is
        against public policy as expressed in such Act and is, therefore,
        unenforceable.

        In the event that a claim for indemnification against such liabilities
        (other than the payment by the registrant of expenses incurred or paid
        by a director, officer or controlling person of the registrant in the
        successful defense of any action, suit or proceeding) is asserted by
        such trustee, officer or controlling person in connection with the
        securities being registered, the registrant will, unless in the opinion
        of its counsel the matter has been settled by controlling precedent,
        submit to a court of appropriate jurisdiction the question whether such
        indemnification it is against public policy as expressed in such
        Act and will be governed by the final adjudication of such issue.

Item 25.   Indemnification (continued)

        Reference is also made to the Distribution Agreement filed as Exhibit
        (6) of Post-Effective Amendment No. 10 to the Registration Statement on
        Form N-1A, filed on December 1, 1994.
