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

Principal Investment Strategy

As a money market fund, the fund is subject to maturity, quality, liquidity and
diversification requirements designed to help it maintain a stable share price
of $1.00. To pursue its goal, the fund normally invests substantially all of its
assets in short-term, high quality municipal obligations that provide income
exempt from federal personal income taxes. The fund also may invest in high
quality, short-term structured notes, which are derivative instruments whose
value is tied to underlying municipal obligations. In addition, the fund may
invest temporarily in high quality, taxable money market instruments, including
when the portfolio manager believes that acceptable municipal obligations are
unavailable for investment.

Although the fund seeks to provide income exempt from federal personal income
tax, income from some of its holdings may be subject to the federal alternative
minimum tax.

Principal Risks

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

The fund's yield will fluctuate as the short-term securities in its portfolio
mature and the proceeds are reinvested in securities with different interest
rates. Additionally, while the fund has maintained a constant share price since
inception, and will continue to try to do so, neither The Dreyfus Corporation
nor its affiliates are required to make a capital infusion, enter into a capital
support agreement or take other actions to prevent the fund's share price from
falling below $1.00. The following are the principal risks that could reduce the
fund's income level and/or share price:

o Interest rate risk. This risk refers to the decline in the prices of
fixed-income securities that may accompany a rise in the overall level of
interest rates. A sharp and unexpected rise in interest rates could cause a
money market fund's share price to drop below a dollar.

o Credit risk. Failure of an issuer to make timely interest or principal
payments, or a decline or perception of a decline in the credit quality of a
security, can cause the security's price to fall, potentially lowering the
fund's share price. The credit quality of the securities held by the fund can
change rapidly in certain market environments, and the default of a single
holding could have the potential to cause significant deterioration of the
fund's net asset value.

o Liquidity risk. When there is little or no active trading market for specific
types of securities, it can become more difficult to sell the securities at or
near their perceived value. In such a market, the value of such securities may
fall dramatically, potentially lowering the fund's share price, even during
periods of declining interest rates. Also, during such periods, redemptions by a
few large investors in the fund may have a significant adverse effect on the
fund's net asset value and remaining fund shareholders.

o Tax risk. To be tax-exempt, municipal obligations generally must meet certain
regulatory requirements. If any such municipal obligation fails to meet these
regulatory requirements, the interest received by the fund from its investment
in such obligations and distributed to fund shareholders will be taxable.

o Structured notes risk. Structured notes, a type of derivative instrument, can
be volatile, and the possibility of default by the financial institution or
counterparty may be greater for these instruments than for other types of money
market instruments. Structured notes typically are purchased in privately
negotiated transactions from financial institutions and, thus, an active trading
market for such instruments may not exist.
