Introduction

Each fund is a money market mutual fund with a separate investment portfolio. The operations and results of one fund are unrelated to those of the other fund. This combined prospectus has been prepared for the convenience of investors so that investors can consider two 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, with the remainder invested in securities with the second-highest credit rating, or the unrated equivalent as determined by Dreyfus. Each fund intends to purchase only securities with the highest credit rating, or the unrated equivalent.

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 a shareholder's 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:

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

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

o 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


Dreyfus Institutional Preferred Money Market Fund

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:

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

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

o repurchase agreements

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

o asset-backed securities

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

MAIN RISKS

The fund's yield will fluctuate, as market conditions and interest rates 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:

o interest rates could rise sharply, causing the value of the fund's securities, and share price, to drop

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

o 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

o 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

Concepts to understand

REPURCHASE AGREEMENT: a U.S. commercial bank or securities dealer sells typically U.S. government securities to the fund and agrees to repurchase them at an agreed-upon date (usually the next day) and price. These agreements offer the fund a means of investing money for a short period of time.


PAST PERFORMANCE

The bar chart and table below show some of the risks of investing in the fund. The bar chart shows the changes in the fund's performance from year to year. The table shows the fund's average annual total return over time. Of course, past performance is no guarantee of future results.

EXPENSES

Fund investors 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. The fund has no sales charge (load) or Rule 12b-1 distribution fees.

This example shows what an investor 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 the investor sold the shares at the end of a period or kept them. Because actual return and expenses will be different, the example is for comparison only.

What this fund is -- and isn't

This fund is a mutual fund: a pooled investment that is professionally managed and gives an investor 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. An investor could lose money in this fund, but also has the potential to make money.

Concepts to understand

MANAGEMENT FEE: the fee paid to Dreyfus for managing the fund. Unlike the arrangements between most investment advisers and their funds, Dreyfus pays all fund expenses except for brokerage fees, taxes, interest, fees and expenses of the independent board members, fees and expenses of independent counsel to the fund and to the independent board members, and extraordinary expenses.

Dreyfus Institutional Preferred Plus Money Market Fund

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 $139 billion in over 160 mutual fund portfolios. For the past fiscal year, Dreyfus Institutional Preferred Money Market Fund paid Dreyfus a management fee at the annual rate of 0.10% of the fund's average daily net assets. Dreyfus Institutional Preferred Plus Money Market Fund has agreed to pay Dreyfus a management fee at the annual rate of 0.10% of the fund's average daily net assets. Dreyfus is the primary mutual fund business of Mellon Financial Corporation, a global financial services company with approximately $2.5 trillion of assets under management, administration or custody, including approximately $485 billion under management. Mellon provides wealth management, global investment services and a comprehensive array of banking services to individuals, businesses and institutions. Mellon is headquartered in Pittsburgh, Pennsylvania.

The funds, Dreyfus and Dreyfus Service Corporation (each fund's distributor) each have adopted a code of ethics that permits its personnel, subject to such code, to invest in securities, including securities that may be purchased or held by each fund. The Dreyfus code of ethics restricts the personal securities transactions of its employees, and requires portfolio managers and other investment personnel to comply with the code's preclearance and disclosure procedures. Its primary purpose is to ensure that personal trading by Dreyfus employees does not disadvantage any Dreyfus-managed fund.


FINANCIAL HIGHLIGHTS

The following table describes Dreyfus Institutional Preferred Money Market Fund's performance for the fiscal periods indicated. "Total return" shows how much an investment in the fund would have increased (or decreased) during each period, assuming reinvestment of 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. No financial information is provided for Dreyfus Institutional Preferred Plus Money Market Fund, which had not commenced operations as of the date of this prospectus.

Financial Highlights


Account Information

ACCOUNT POLICIES

Each fund is designed for institutional investors, particularly colleges and universities, for the investment of endowment and other funds. Fund shares will not be sold to institutions which desire to use the funds as a commercial sweep account, or to individuals.

Buying shares

Investors pay no sales charges to invest in these funds. The price for fund shares is the fund's net asset value per share (NAV), which is generally calculated at 5:00 p.m. every day the New York Stock Exchange or the fund's transfer agent is open. Orders in proper form will be priced at the NAV next calculated after the orders and Federal Funds are received by the fund's custodian or other authorized entity.

Investors whose orders are placed and payments are received in or converted into Federal Funds by the fund's custodian by 12:00 noon, will become effective at the price determined at 5:00 p.m. and will receive the dividend declared on that day. Except as described below, investors whose payments are received in or converted into Federal Funds after 12:00 noon by the fund's custodian, will begin to accrue dividends on the following business day.

Orders in proper form received by Dreyfus Institutional Services Division after 12:00 noon, but prior to 5:00 p.m., and payments for which are received by the fund's custodian by 6:00 p.m., will become effective at the price determined at 5:00 p.m., and the shares so purchased will receive the dividend declared on such day.

For each fund, all times are Eastern time.

Each fund's investments are valued based on amortized cost.

--------------------------------------------------------------------------------
Minimum investments

                                Initial                Additional
--------------------------------------------------------------------------------
REGULAR ACCOUNTS                $1 BILLION*            NO MINIMUM

*The minimum initial investment is $1 billion, unless: (a) the investor has invested at least $1 billion in one fund, in which case there would be no minimum initial investment amount for the other fund; or (b) the investor has, in the opinion of Dreyfus Institutional Services Division, adequate intent and availability of assets to reach a future aggregate level of investment of $1 billion in the funds.

Concepts to understand

NET ASSET VALUE (NAV): a mutual fund's share price on a given day. A fund's NAV is calculated by dividing the value of its net assets by the number of existing shares.

AMORTIZED COST: a method of valuing a money market fund's portfolio securities, which does not take into account unrealized gains and losses. As a result, portfolio securities are valued at their acquisition cost, adjusted over time based on the discounts or premiums reflected in their purchase price. This method of valuation is designed to permit a fund to maintain a stable net asset value.


Selling shares

Investors may sell (redeem) shares at any time and the shares will be sold at the next determined NAV. If a request for redemption is received in proper form, and transmitted to the fund's custodian by 5:00 p.m. Eastern 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. If the request is received later 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. Orders will be processed promptly and investors generally will receive the proceeds within a week. Any certificates representing fund shares being sold must be returned with the redemption request.

General policies

Unless an 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:

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

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

o change its minimum investment amounts

o 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 the investor is redeeming is large enough to affect fund operations (for example, if it represents more than 1% of the fund's assets).

Account Information

DISTRIBUTIONS AND TAXES

Each fund usually declares dividends from its net investment income every day the New York Stock Exchange or the fund's transfer agent is open, and pays such dividends to its shareholders once a month. Each fund distributes any net capital gains it has realized 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.

Fund dividends and distributions are taxable to most U.S. investors as ordinary income (unless the investor's 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 distributions are reinvested or taken in cash. The tax status of dividends and distributions will be detailed in an annual tax statement from the fund.

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

SERVICES FOR FUND INVESTORS

Exchange privilege

An investor may purchase, in exchange for shares of one fund, shares of the other fund. 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 shares of one fund, in shares of the other fund, if the investor is a shareholder in such other fund. There is currently no fee for this privilege.

DESCRIPTION OF THE COMPANY AND THE FUNDS

The Company is a Massachusetts business trust that was formed and commenced operations on June 11, 1997. Prior to October 3, 2000, the Company's name was Dreyfus Institutional Preferred Money Market Fund. Each Fund is a separate portfolio of the Company, an open-end management investment company, known as a money market mutual fund. Each Fund is a diversified fund, which means that, with respect to 75% of the Fund's total assets, the Fund will not invest more than 5% of its assets in the securities of any single issuer.

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

Dreyfus Service Corporation (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. GOVERNMENT SECURITIES. (All Funds) Each Fund may invest in securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities, which include U.S. Treasury securities, that differ in their interest rates, maturities and times of issuance. 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 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. 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.

FOREIGN GOVERNMENT OBLIGATIONS; SECURITIES OF SUPRANATIONAL ENTITIES. (Dreyfus Institutional Preferred Plus Money Market Fund only) The Fund may invest in obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions, agencies or instrumentalities that are determined by the Manager to be of comparable quality to the other obligations in which the Fund may invest. Such securities also include debt obligations of supranational entities. Supranational entities include organizations designated or supported by governmental entities to promote economic reconstruction or development and international banking institutions and related government agencies. Examples include the International Bank for Reconstruction and Development (the World Bank), the European Coal and Steel Community, the Asian Development Bank and the InterAmerican Development Bank.

BANK OBLIGATIONS. (All Funds) Each Fund 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.

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 Federal Deposit Insurance Corporation (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 Bank Insurance Fund administered 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 or state laws and regulations, domestic branches of domestic banks whose CDs may be purchased by a Fund are, among other things, generally required to maintain specified levels of reserves, are limited in the amounts which they can loan to a single borrower and are subject to other regulation designed to promote financial soundness. However, not all of such laws and regulations apply to the foreign branches of domestic banks.

Obligations of foreign branches of domestic banks, foreign subsidiaries of domestic banks and domestic and foreign branches of foreign banks, such as CDs and TDs, 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 of domestic banks, by foreign subsidiaries of domestic banks, by foreign branches of foreign banks or by domestic branches of foreign banks, the Manager carefully evaluates such investments on a case-by-case basis.

Each Fund may purchase CDs issued by banks, savings and loan associations and similar thrift institutions with less than $1 billion in assets, whose deposits are insured by the FDIC, provided the Fund purchases any such CD in a principal amount of not 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 so insured. The Fund will not own more than one such CD per such issuer.

COMMERCIAL PAPER. (All Funds) Each Fund may purchase commercial paper consisting of short-term, unsecured promissory notes issued to finance short-term credit needs. The commercial paper purchased by the Funds will consist only of direct obligations issued by domestic and foreign entities. The other corporate obligations in which each Fund 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. (All Funds) Each Fund 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.

REPURCHASE AGREEMENTS. (All Funds) Each Fund 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 Funds' custodian will have custody of, and will segregate, securities acquired by a Fund under a repurchase agreement. Repurchase agreements are considered by the staff of the Securities and Exchange Commission to be loans by the Fund that enters into them. 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 the Fund's ability to dispose of the underlying securities. In an attempt to reduce the risk of incurring a loss on a repurchase agreement, each 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 the Fund may invest, and will require that additional securities be deposited with it if the value of the securities purchased should decrease below the resale price.

ASSET-BACKED SECURITIES. (All Funds) Each Fund may invest in 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 institutions providing the credit support.

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. Such 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

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

BORROWING MONEY. (All Funds) Each Fund is permitted to borrow to the extent permitted under the Investment Company Act of 1940, as amended (the "1940 Act"), which permits an investment company to borrow an amount up to 33-1/3% of the value of its total assets. Except for when it enters into reverse repurchase agreements described below, each Fund currently intends to borrow money only for temporary or emergency (not leveraging) purposes in an amount up to 15% of the value of its total assets (including the amount borrowed) at the time the borrowing is made. While such borrowings exceed 5% of the value of a Fund's total assets, the Fund will not make any additional investments. In addition, each Fund may borrow for investment purposes on a secured basis through entering into reverse repurchase agreements, as described below.

REVERSE REPURCHASE AGREEMENTS. (All Funds) Each Fund may enter into reverse repurchase agreements with banks, broker/dealers or other financial institutions. These 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 the return received on the securities purchased. Reverse repurchase agreements constitute borrowings under the 1940 Act and, therefore, together with other borrowings, will be subject to the limitations on borrowing set forth in the 1940 Act. To the extent a Fund enters into a reverse repurchase agreement, the Fund will segregate permissible liquid assets at least 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.

LENDING PORTFOLIO SECURITIES. (All Funds) Each Fund 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% of the value of the Fund's total assets, and the Fund will receive collateral consisting of cash or U.S. Government 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 with the Fund. In connection with its securities lending transactions, a 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.

FORWARD COMMITMENTS. (All Funds) Each Fund may purchase money market instruments 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. A 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 Fund's purchase commitments.

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 forward commitment or 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.

INVESTMENTS CONSIDERATIONS AND RISKS

GENERAL. (All Funds) Each Fund attempts to increase yields by trading to take advantage of short-term market variations. This policy is expected to result in high portfolio turnover but should not adversely affect the Funds since the Funds usually do not pay brokerage commissions when purchasing short-term obligations. The value of the portfolio securities held by a Fund will vary inversely to changes in prevailing interest rates. Thus, if interest rates have increased from the time a security was purchased, such security, if sold, might be sold at a price less than its cost. Similarly, if interest rates have declined from the time a security was purchased, such security, if sold, might be sold at a price greater than its purchase cost. In either instance, if the security was purchased at face value and held to maturity, no gain or loss would be realized.

BANK SECURITIES. (All Funds) To the extent a Fund's 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. Each Fund, however, will seek to minimize its exposure to such risks by investing only in debt securities which are determined to be of highest quality.

FOREIGN SECURITIES. (All Funds) Since a Fund's portfolio may contain securities issued by foreign branches of domestic banks, domestic and foreign branches of foreign banks, and commercial paper issued by foreign issuers, the Fund may be subject to additional investment risks with respect to such 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.

SIMULTANEOUS INVESTMENTS. (All Funds) Investment decisions for each Fund are made independently from those of the other Fund and other investment companies advised by the Manager. If, however, such other Fund or 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 a Fund or the price paid or received by a 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, each Fund has adopted investment restrictions numbered 1 through 9 as fundamental policies. Investment restrictions numbered 10 and 11 are not fundamental policies and may be changed, as to a Fund, by vote of a majority of the Company's Board members at any time. Neither Fund may:

1. Invest in commodities.

2. Borrow money, except to the extent permitted under the 1940 Act, which currently limits borrowing to up to 33-1/3% of the value of the Fund's total assets.

3. Purchase or sell securities on margin.

4. Issue any senior security (as such term is defined in Section 18(f) of the 1940 Act).

5. Act as underwriter of securities of other issuers, except to the extent the Fund may be deemed an underwriter under the Securities Act of 1933, as amended, by virtue of disposing of portfolio securities.

6. Purchase, hold or deal in real estate, or oil, gas, or other mineral leases or exploration or development programs, but the Fund may purchase and sell securities that are secured by real estate or issued by companies that invest in or deal in real estate.

7. Make loans to others except through the purchase of debt obligations and the entry into repurchase agreements. However, the Fund may lend its portfolio securities in an amount not to exceed 33-1/3% of the value of its total assets. Any loans of portfolio securities will be made according to guidelines established by the Securities and Exchange Commission and the Company's Board.

8. Invest more than 5% of its assets in the obligations of any one issuer, except that up to 25% of the value of the Fund's total assets may be invested without regard to any such limitations.

9. Invest less than 25% of its total assets in securities issued by banks or invest more than 25% in the securities of issuers in any other industry, provided that there shall be no limitation on the purchase of obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities. Notwithstanding the foregoing, for temporary defensive purposes the Fund may invest less than 25% of its assets in bank obligations.

10. Pledge, mortgage, hypothecate or otherwise encumber its assets, except to the extent necessary to secure permitted borrowings and to the extent related to the deposit of assets in escrow in connection with the purchase of securities on a when-issued or forward commitment basis.

11. Enter into repurchase agreements providing for settlement in more than seven days after notice or purchase securities which are illiquid if, in the aggregate, more than 10% of the value of the Fund's net assets would be so invested.

If a percentage restriction is adhered to at the time of investment, a later increase or decrease in percentage resulting from a change in values or assets will not constitute a violation of that restriction.

MANAGEMENT ARRANGEMENTS

INVESTMENT ADVISER. The Manager is a wholly-owned subsidiary of Mellon Bank, N.A., which is a wholly-owned subsidiary of Mellon Financial Corporation ("Mellon"). Mellon is a global multibank financial holding company 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 largest bank holding companies in the United States based on total assets.

The Manager provides management services pursuant to the Management Agreement (the "Agreement") between the Manager and the Company. As to each Fund, the Agreement is subject to annual approval by (i) the Company's Board or
(ii) vote of a majority (as defined in the 1940 Act) of the Fund's outstanding voting securities, provided that in either event the continuance also is approved by a majority of the Board members who are not "interested persons" (as defined in the 1940 Act) of the Company or the Manager, by vote cast in person at a meeting called for the purpose of voting on such approval. As to each Fund, the Agreement is terminable without penalty on 60 days' notice by the Board or by vote of the holders of a majority of the Fund's shares or, upon not less than 90 days' notice, by the Manager. The Agreement will terminate automatically, as to the relevant Fund, in the event of its assignment (as defined in the 1940 Act).

The following persons are officers and/or directors of the Manager:
Christopher M. Condron, Chairman of the Board and Chief Executive Officer; Stephen E. Canter, President, Chief Operating Officer, Chief Investment Officer and a director; Thomas F. Eggers, Vice Chairman--Institutional and a director; Lawrence S. Kash, Vice Chairman; J. David Officer, Vice Chairman and a director; Ronald P. O'Hanley III, Vice Chairman; William T. Sandalls, Jr., Executive Vice President; Stephen R. Byers, Senior Vice President; Patrice M. Kozlowski, Senior Vice President--Corporate Communications; Mark N. Jacobs, Vice President, General Counsel and Secretary; Diane P. Durnin, Vice President--Product Development; Mary Beth Leibig, Vice President--Human Resources; Ray Van Cott, Vice President--Information Systems; Theodore A. Schachar, Vice President--Tax; Wendy Strutt, Vice President; William H. Maresca, Controller; James Bitetto, Assistant Secretary; Steven F. Newman, Assistant Secretary; and Mandell L. Berman, Burton C. Borgelt, Steven G. Elliot, Martin G. McGuinn, Richard W. Sabo and Richard F. Syron, directors.

The Manager manages each Fund's portfolio of investments in accordance with the stated policies of the Fund, subject to the approval of the Company's Board. The Manager is responsible for investment decisions, and provides the Funds with portfolio managers who are authorized by the Company's Board to execute purchases and sales of securities. The Funds' portfolio managers are Bernard W. Kiernan, Jr., Patricia A. Larkin and Thomas Riordan. The Manager also maintains a research department with a professional staff of securities analysts who provide research services for the Funds and for other funds advised by the Manager.

The Manager's Code of Ethics subjects its employees' personal securities transactions to various restrictions to ensure that such trading does not disadvantage any fund advised by the Manager. In that regard, portfolio managers and other investment personnel of the Manager must preclear and report their personal securities transactions and holdings, which are reviewed for compliance with the Code of Ethics, and are also subject to the oversight of Mellon's Investment Ethics Committee. Portfolio managers and other investment personnel who comply with the Code of Ethic's preclearance and disclosure procedures and the requirements of the Committee, may be permitted to purchase, sell or hold securities which also may be or are held in fund(s) they manage or for which they otherwise provide investment advice.

The Manager maintains office facilities on behalf of the Company and furnishes statistical and research data, clerical help, accounting, data processing, bookkeeping and internal auditing and certain other required services to the Company. 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 securities dealers, banks or other financial institutions 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.

All expenses incurred in the operation of the Company are borne by the Manager, except the management fee, taxes, interest, brokerage fees and commissions, if any, fees and expenses of non-interested Board members, fees and expenses of independent counsel to the Company and to the non-interested Board members, and any extraordinary expenses.

As compensation for the Manager's services, the Company has agreed to pay the Manager a monthly fee at the annual rate of 0.10% of the value of each Fund's average daily net assets. All fees and expenses are accrued daily and deducted before declaration of dividends to shareholders. The Manager has agreed to reduce its management fee in an amount equal to the accrued fees and expenses of the non-interested Board members, and the fees and expenses of independent counsel to the Company and to the non-interested Board members. The management fees paid by Dreyfus Institutional Preferred Money Market Fund to the Manager for the period June 11, 1997 (commencement of operations) through March 31, 1998 and the fiscal years ended March 31, 1999 and 2000, amounted to $853,116, $1,722,571 and $2,576,727, respectively. Dreyfus Institutional Preferred Plus Money Market Fund had not commenced operations as of the date of this Statement of Additional Information.

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

DISTRIBUTOR. The Distributor, a wholly-owned subsidiary of the Manager located at 200 Park Avenue, New York, New York 10166, serves as each Fund's distributor on a best efforts basis pursuant to an agreement with the Company 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 the Company's transfer and dividend disbursing agent. Under a transfer agency agreement with the Company, the Transfer Agent arranges for the maintenance of shareholder account records for each 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 computed on the basis of the number of shareholder accounts it maintains for each Fund during the month, and is reimbursed for certain out-of-pocket expenses.

The Bank of New York (the "Custodian"), 100 Church 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 the Funds. Under a custody agreement with the Company, the Custodian holds each Fund's securities and keeps all necessary accounts and records.

HOW TO BUY SHARES

Each Fund is designed for institutional investors, particularly colleges and universities for the investment of endowment and other funds. Fund shares will not be sold to institutions which desire to use the Funds as commercial sweep accounts.

The minimum initial investment is $1 billion, unless the investor has invested at least $1 billion in one Fund, in which case there wold be no minimum initial investment amount for the other Fund, or the investor has, in the opinion of Dreyfus Institutional Services Division, a division of the Distributor, adequate intent and availability of funds to reach a future aggregate level of investment of $1 billion in the Funds. 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. The Company reserves the right to reject any purchase order.

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 by any agent or entity subject to the direction of such agents. 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.

Each Fund's net asset value per share is determined as of 5:00 p.m., New York time, on each day the New York Stock Exchange or the Transfer Agent is open for business. Net asset value per share is computed by dividing the value of the Fund's net assets (i.e., the value of its assets less liabilities) by the total number of the Fund's shares outstanding. See "Determination of Net Asset Value."

Investors whose orders are placed and payments are received in or converted into Federal Funds by the Custodian by 12:00 Noon, New York time, will become effective at the price determined at 5:00 p.m., New York time, and will receive the dividend declared on such day. Except as described below, investors whose payments are received in or converted into Federal Funds after 12:00 Noon, New York time, by the Custodian, will begin to accrue dividends on the following business day.

Orders in proper form received by Dreyfus Institutional Services Division in New York after 12:00 Noon, New York time, but prior to 5:00 p.m., New York time, and payments for which are received by the Custodian by 6:00
p.m., New York time, will become effective at the price determined at 5:00 p.m., New York time, and the shares so purchased will receive the dividend declared on such day.

USING FEDERAL FUNDS. The Transfer Agent or the Company 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.

HOW TO REDEEM SHARES

WIRE REDEMPTION PRIVILEGE. By using this privilege, the investor authorizes the Transfer Agent to act on wire, telephone or letter 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. Ordinarily, the Company will initiate payment for shares redeemed pursuant to this privilege on the same business day if Dreyfus Institutional Services Division receives the redemption request in proper form in New York by 5:00 p.m., New York time; otherwise the Company will initiate payment on the next business day. 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 inform the operator of the Transfer Agent's answer back sign.

The Company reserves the right to refuse any request made by wire or telephone and may limit the amount involved or the number of telephone redemptions. This procedure may be modified or terminated at any time by the Transfer Agent or the Company. Shares for which certificates have been issued may not be redeemed by wire or telephone.

REDEMPTION THROUGH COMPATIBLE AUTOMATED FACILITIES. Each Fund makes available to institutions the ability to redeem shares through a compatible automated interface or trading system. Investors desiring to redeem shares in this manner should call Dreyfus Institutional Services Division at one of the telephone numbers listed on the cover of this Statement of Additional Information to determine whether their automated facilities are compatible and to receive instructions for redeeming shares in this manner.

REDEMPTION COMMITMENT. The Company has committed to pay in cash all redemption requests by any shareholders of record, limited in amount during any 90-day period to the lesser of $250,000 or 1% of the value of a Fund's net assets at the beginning of such period. Such commitment is irrevocable without the prior approval of the Securities and Exchange Commission. In the case of requests for redemption in excess of such amount, the Company's 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 (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 relevant 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.

The Company's Board has established, as a particular responsibility within the overall duty of care owed to each Fund's investors, procedures reasonably designed to stabilize each Fund's price per share as computed for the purpose of purchases and redemptions at $1.00. Such procedures include review of each Fund's portfolio holdings by the Company's Board, at such intervals as it deems appropriate, to determine whether the Fund's net asset value per share 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 will be valued at fair value as determined in good faith by the Company's Board.

The extent of any deviation between a Fund's net asset value based upon available market quotations or market equivalents and $1.00 per share based on amortized cost will be examined by the Company's Board. If such deviation exceeds 1/2%, the Company's Board will consider promptly what action, if any, will be initiated. In the event the Company'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 by using available market quotations or market equivalents.

NEW YORK STOCK EXCHANGE AND TRANSFER AGENT CLOSINGS. The following are the holidays (as observed) on which both the New York Stock Exchange and the Transfer Agent currently are closed: 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 Fund may be exchanged for shares of the other Fund. 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.

No fees currently are charged shareholders directly in connection with exchanges, although the Company 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 Fund, shares of the other Fund if the investor is a shareholder in such other 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 Company 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 Dreyfus Institutional Preferred Money Market Fund has qualified for the fiscal year ended March 31, 2000 as a "regulated investment company" under the Internal Revenue Code of 1986, as amended (the "Code"). It is expected that Dreyfus Institutional Preferred Plus Money Market Fund will qualify as a regulated investment company under the Code. Each 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 a 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.

Each Fund ordinarily declares dividends from net investment income on each day the New York Stock Exchange or the Transfer Agent is open for business. Each Fund's earnings for Saturdays, Sundays and holidays are declared as dividends on the preceding business day. Dividends usually are paid on the last calendar day of each month, and automatically are reinvested in additional shares of the Fund at net asset value or, at the investor's option, paid in cash. If an investor redeems all shares in its account at any time during the month, all dividends to which the investor is entitled are paid along with the proceeds of the redemption.

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

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 will be paid by the Funds for such purchases. Purchases from underwriters of portfolio securities may 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 reflect the spread between the bid and asked price.

Transactions will be allocated to various dealers by the Funds' portfolio managers in their best judgment. The primary consideration will be 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 the Funds or other funds advised by the Manager or its affiliates.

Research services furnished by brokers through which the Funds will effect 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 the Funds. 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 INFORMATION

For the seven-day period ended March 31, 2000, Dreyfus Institutional Preferred Money Market Fund's yield and effective yield were 6.02% and 6.20%, respectively. Dreyfus Institutional Preferred Plus Money Market Fund had not commenced operations as of the date of this Statement of Additional Information.

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 the shareholder's account, 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.

Yields will fluctuate and are not necessarily representative of future results. Each 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 a Fund is not guaranteed. See "Determination of Net Asset Value" for a discussion of the manner in which each Fund's price per share is determined.

Comparative performance information may be used from time to time in advertising or marketing the Funds' shares, including data from Lipper Analytical Services, Inc., Bank Rate Monitor(TM), IBC's Money Fund Report(TM), Morningstar, Inc. and other industry publications.

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 a trillion dollar industry. Currently, the Manager manages approximately $55 billion in money market fund assets, including approximately $43 billion in money market funds designed for institutional investors.

INFORMATION ABOUT THE COMPANY AND THE FUNDS

Each Fund share has one vote and, when issued and paid for in accordance with the terms of the offering, is fully paid and nonassessable. Fund shares are of one class and have equal rights as to dividends and in liquidation. Shares have no preemptive, subscription or conversion rights, and are freely transferable.

The Company is organized as an unincorporated business trust under the laws of the Commonwealth of Massachusetts. Under Massachusetts law, shareholders of a Fund could, under certain circumstances, be held personally liable for the obligations of that Fund. However, the Company's Agreement and Declaration of Trust (the "Trust Agreement") disclaims shareholder liability for acts or obligations of the Company and requires that notice of such disclaimer be given in the agreement, obligation or instrument entered into or executed by the Company or a Board member. The 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 incurring financial loss on account of a 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, the shareholder paying such liability will be entitled to reimbursement from the general assets of the Fund. The Company intends to conduct its operations in a way so as to avoid, as far as possible, ultimate liability of the shareholders for liabilities of the Funds.

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. Thus, shareholder of one Fund is not deemed to be a shareholder of any other Fund. For certain matters shareholders vote together as a group; as to others they vote separately by Fund.

To date, the Board has authorized the creation of two series of shares. All consideration received by the Company for shares of a Fund, and all assets in which such consideration is invested, will belong to that Fund (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, a Fund will be treated separately from those of the other Fund. 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 Fund affected by such matter. Rule 18f-2 further provides that a Fund shall be deemed to be affected by a matter unless it is clear that the interests of each Fund in the matter are identical or that the matter does not affect any interest of such Fund. However, the Rule exempts the selection of independent accountants and the election of Board members from the separate voting requirements of the Rule.

Unless otherwise required by the 1940 Act, ordinarily it will not be necessary for the Company to hold annual meetings of shareholders. As a result, 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 Company to hold a special meeting of shareholders for purposes of removing a Board member from office. Shareholders may remove a Board member by the affirmative vote of two-thirds of the Company's outstanding voting shares. In addition, the 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.

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

COUNSEL AND INDEPENDENT AUDITORS

Stroock & Stroock & Lavan LLP, 180 Maiden Lane, New York, New York 10038-4982, as counsel for the Company, 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' Prospectus.

Ernst & Young LLP 787, Seventh Avenue, New York, New York 10019, independent auditors, have been selected as independent auditors of the Company.


APPENDIX

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 Grade) is the highest commercial paper rating assigned by Fitch. Paper rated Fitch-1 is regarded as having the strongest degree of assurance for timely payment.

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.

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 strictly high grade, broadly marketable and suitable for investment by trustees and fiduciary institutions and liable to but slight market fluctuation other than through changes in the money rate. The prime feature of an AAA bond is a showing of earnings several times or many times interest requirements, with such stability of applicable earnings that safety is beyond reasonable question whatever changes occur in conditions.

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 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.

In addition to ratings of short-term obligations, BankWatch assigns a rating to each issuer it rates, in gradations of A through E. 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 the bank is domiciled.

ITEM 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT.

Not Applicable

ITEM 25. INDEMNIFICATION

Reference is made to Article EIGHTH of the Registrant's Amended and Restated Declaration of Trust, filed as Exhibit 1 to Pre-Effective Amendment No. 1. The application of these provisions is limited by Article 10 of the Registrant's By-laws, filed as Exhibit 2 to Pre-Effective Amendment No. 1, 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 trustee, 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 a controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in such Act and will be governed by the final adjudication of such issue.

Reference is also made to the Amended Distribution Agreement filed as Exhibit (e).

Dear Sirs:

The above-named investment company (the "Fund") consisting of the series named on Schedule 1 hereto, as such Schedule may be revised from time to time (each, a "Series"), herewith confirms its agreement with you as follows:

The Fund desires to employ its capital by investing and reinvesting the same in investments of the type and in accordance with the limitations specified in its charter documents and in each Series' Prospectus and Statement of Additional Information as from time to time in effect, copies of which have been or will be submitted to you, and in such manner and to such extent as from time to time may be approved by the Fund's Board. The Fund desires to employ you to act as its investment adviser.

In this connection it is understood that from time to time you will employ or associate with yourself such person or persons as you may believe to be particularly fitted to assist you in the performance of this Agreement. Such person or persons may be officers or employees who are employed by both you and the Fund. The compensation of such person or persons shall be paid by you and no obligation may be incurred on the Fund's behalf in any such respect.

Subject to the supervision and approval of the Fund's Board, you will provide investment management of each Series' portfolio in accordance with such Series' investment objectives and policies as stated in the Series' Prospectus and Statement of Additional Information as from time to time in effect. In connection therewith, you will obtain and provide investment research and will supervise each Series' investments and conduct a continuous program of investment, evaluation and, if appropriate, sale and reinvestment of such Series' assets. You will furnish to the Fund such statistical information, with respect to the investments which a Series may hold or contemplate purchasing, as the Fund may reasonably request. The Fund wishes to be informed of important developments materially affecting any Series' portfolio and shall expect you, on your own initiative, to furnish to the Fund from time to time such information as you may believe appropriate for this purpose.

In addition, you will supply office facilities (which may be in your own offices), data processing services, clerical, accounting and bookkeeping services, internal auditing and legal services, internal executive and administrative services, and stationery and office supplies; prepare reports to each Series' stockholders, tax returns, reports to and filings with the Securities and Exchange Commission and state Blue Sky authorities; calculate the net asset value of each Series' shares; and generally assist in all aspects of the Fund's operations. You shall have the right, at your expense, to engage other entities to assist you in performing some or all of the obligations set forth in this paragraph, provided each such entity enters into an agreement with you in form and substance reasonably satisfactory to the Fund. You agree to be liable for the acts or omissions of each such entity to the same extent as if you had acted or failed to act under the circumstances.

You shall exercise your best judgment in rendering the services to be provided to the Fund hereunder and the Fund agrees as an inducement to your undertaking the same that you shall not be liable hereunder for any error of judgment or mistake of law or for any loss suffered by one or more Series, provided that nothing herein shall be deemed to protect or purport to protect you against any liability to the Fund or a Series or to its security holders to which you would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of your duties hereunder, or by reason of your reckless disregard of your obligations and duties hereunder.

In consideration of services rendered pursuant to this Agreement, the Fund will pay you on the first business day of each month a fee at the rate set forth opposite each Series' name on Schedule 1 hereto. Net asset value shall be computed on such days and at such time or times as described in the Fund's then-current Prospectus and Statement of Additional Information. The fee for the period from the date of the commencement of the public sale of a Series' shares to the end of the month during which such sale shall have been commenced shall be pro-rated according to the proportion which such period bears to the full monthly period, and upon any termination of this Agreement before the end of any month, the fee for such part of a month shall be pro-rated according to the proportion which such period bears to the full monthly period and shall be payable upon the date of termination of this Agreement.

For the purpose of determining fees payable to you, the value of each Series' net assets shall be computed in the manner specified in the Fund's charter documents for the computation of the value of each Series' net assets.

You will bear all expenses in connection with the performance of your services under this Agreement, as well as all other expenses to be incurred in the operation of the Fund, except the management fees payable hereunder, interest, taxes, brokerage fees and commissions, if any, fees pursuant to any distribution or shareholder services plan adopted by the Fund, fees and expenses of the Board members who are not "interested persons" (as defined in the Investment Company Act of 1940, as amended) of the Fund (the "Non-Interested Board Members"), fees and expenses of independent counsel to the Fund and to the Non-Interested Board Members, and any extraordinary expenses.

The Fund understands that you now act, and that from time to time hereafter you may act, as investment adviser to one or more other investment companies and fiduciary or other managed accounts, and the Fund has no objection to your so acting, provided that when the purchase or sale of securities of the same issuer is suitable for the investment objectives of two or more companies or accounts managed by you which have available funds for investment, the available securities will be allocated in a manner believed by you to be equitable to each company or account. It is recognized that in some cases this procedure may adversely affect the price paid or received by one or more Series or the size of the position obtainable for or disposed of by one or more Series.

In addition, it is understood that the persons employed by you to assist in the performance of your duties hereunder will not devote their full time to such service and nothing contained herein shall be deemed to limit or restrict your right or the right of any of your affiliates to engage in and devote time and attention to other businesses or to render services of whatever kind or nature.

You shall not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund in connection with the matters to which this Agreement relates, except for a loss resulting from willful misfeasance, bad faith or gross negligence on your part in the performance of your duties or from reckless disregard by you of your obligations and duties under this Agreement. Any person, even though also your officer, director, partner, employee or agent, who may be or become an officer, Board member, employee or agent of the Fund, shall be deemed, when rendering services to the Fund or acting on any business of the Fund, to be rendering such services to or acting solely for the Fund and not as your officer, director, partner, employee or agent or one under your control or direction even though paid by you.

As to each Series, this Agreement shall continue until the date set forth opposite such Series' name on Schedule 1 hereto (the "Reapproval Date"), and thereafter shall continue automatically for successive annual periods ending on the day of each year set forth opposite the Series' name on Schedule 1 hereto (the "Reapproval Day"), provided such continuance is specifically approved at least annually by (i) the Fund's Board or (ii) vote of a majority (as defined in the Investment Company Act of 1940) of such Series' outstanding voting securities, provided that in either event its continuance also is approved by a majority of the Non-Interested Board Members, by vote cast in person at a meeting called for the purpose of voting on such approval. As to each Series, this Agreement is terminable without penalty, on 60 days' notice, by the Fund's Board or by vote of holders of a majority of such Series' shares or, upon not less than 90 days' notice, by you. This Agreement also will terminate automatically, as to the relevant Series, in the event of its assignment (as defined in said Act).

The Fund recognizes that from time to time your directors, officers and employees may serve as directors, trustees, partners, officers and employees of other corporations, business trusts, partnerships or other entities (including other investment companies) and that such other entities may include the name "Dreyfus" as part of their name, and that your corporation or its affiliates may enter into investment advisory or other agreements with such other entities. If you cease to act as the Fund's investment adviser, the Fund agrees that, at your request, the Fund will take all necessary action to change the name of the Fund to a name not including "Dreyfus" in any form or combination of words.

This Agreement has been executed on behalf of the Fund by the undersigned officer of the Fund in his capacity as an officer of the Fund. The obligations of this Agreement shall only be binding upon the assets and property of the Fund or the affected Series, as the case may be, and shall not be binding upon any Board member, officer or shareholder of the Fund individually.

If the foregoing is in accordance with your understanding, will you kindly so indicate by signing and returning to us the enclosed copy hereof.

Very truly yours,

Ladies and Gentlemen:

This is to confirm that, in consideration of the agreements hereinafter contained, the above-named investment company (the "Fund") has agreed that you shall be, for the period of this agreement, the distributor of
(a) shares of each Series of the Fund set forth on Exhibit A hereto, as such Exhibit may be revised from time to time (each, a "Series") or (b) if no Series are set forth on such Exhibit, shares of the Fund. For purposes of this agreement the term "Shares" shall mean the authorized shares of the relevant Series, if any, and otherwise shall mean the Fund's authorized shares.

1. Services as Distributor

1.1 You will act as agent for the distribution of Shares covered by, and in accordance with, the registration statement and prospectus then in effect under the Securities Act of 1933, as amended, and will transmit promptly any orders received by you for purchase or redemption of Shares to the Transfer and Dividend Disbursing Agent for the Fund of which the Fund has notified you in writing.

1.2 You agree to use your best efforts to solicit orders for the sale of Shares. It is contemplated that you will enter into sales or servicing agreements with securities dealers, financial institutions and other industry professionals, such as investment advisers, accountants and estate planning firms, and in so doing you will act only on your own behalf as principal.

1.3 You shall act as distributor of Shares in compliance with all applicable laws, rules and regulations, including, without limitation, all rules and regulations made or adopted pursuant to the Investment Company Act of 1940, as amended, by the Securities and Exchange Commission or any securities association registered under the Securities Exchange Act of 1934, as amended.

1.4 Whenever in their judgment such action is warranted by market, economic or political conditions, or by abnormal circumstances of any kind, the Fund's officers may decline to accept any orders for, or make any sales of, any Shares until such time as they deem it advisable to accept such orders and to make such sales and the Fund shall advise you promptly of such determination.

1.5 The Fund agrees to pay all costs and expenses in connection with the registration of Shares under the Securities Act of 1933, as amended, and all expenses in connection with maintaining facilities for the issue and transfer of Shares and for supplying information, prices and other data to be furnished by the Fund hereunder, and all expenses in connection with the preparation and printing of the Fund's prospectuses and statements of additional information for regulatory purposes and for distribution to shareholders; provided, however, that nothing contained herein shall be deemed to require the Fund to pay any of the costs of advertising the sale of Shares.

1.6 The Fund agrees to execute any and all documents and to furnish any and all information and otherwise to take all actions which may be reasonably necessary in the discretion of the Fund's officers in connection with the qualification of Shares for sale in such states as you may designate to the Fund and the Fund may approve, and the Fund agrees to pay all expenses which may be incurred in connection with such qualification. You shall pay all expenses connected with your own qualification as a dealer under state or Federal laws and, except as otherwise specifically provided in this agreement, all other expenses incurred by you in connection with the sale of Shares as contemplated in this agreement.

1.7 The Fund shall furnish you from time to time, for use in connection with the sale of Shares, such information with respect to the Fund or any relevant Series and the Shares as you may reasonably request, all of which shall be signed by one or more of the Fund's duly authorized officers; and the Fund warrants that the statements contained in any such information, when so signed by the Fund's officers, shall be true and correct. The Fund also shall furnish you upon request with: (a) semi-annual reports and annual audited reports of the Fund's books and accounts made by independent public accountants regularly retained by the Fund, (b) quarterly earnings statements prepared by the Fund, (c) a monthly itemized list of the securities in the Fund's or, if applicable, each Series' portfolio, (d) monthly balance sheets as soon as practicable after the end of each month, and (e) from time to time such additional information regarding the Fund's financial condition as you may reasonably request.

1.8 The Fund represents to you that all registration statements and prospectuses filed by the Fund with the Securities and Exchange Commission under the Securities Act of 1933, as amended, and under the Investment Company Act of 1940, as amended, with respect to the Shares have been carefully prepared in conformity with the requirements of said Acts and rules and regulations of the Securities and Exchange Commission thereunder. As used in this agreement the terms "registration statement" and "prospectus" shall mean any registration statement and prospectus, including the statement of additional information incorporated by reference therein, filed with the Securities and Exchange Commission and any amendments and supplements thereto which at any time shall have been filed with said Commission. The Fund represents and warrants to you that any registration statement and prospectus, when such registration statement becomes effective, will contain all statements required to be stated therein in conformity with said Acts and the rules and regulations of said Commission; that all statements of fact contained in any such registration statement and prospectus will be true and correct when such registration statement becomes effective; and that neither any registration statement nor any prospectus when such registration statement becomes effective will include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Fund may but shall not be obligated to propose from time to time such amendment or amendments to any registration statement and such supplement or supplements to any prospectus as, in the light of future developments, may, in the opinion of the Fund's counsel, be necessary or advisable. If the Fund shall not propose such amendment or amendments and/or supplement or supplements within fifteen days after receipt by the Fund of a written request from you to do so, you may, at your option, terminate this agreement or decline to make offers of the Fund's securities until such amendments are made. The Fund shall not file any amendment to any registration statement or supplement to any prospectus without giving you reasonable notice thereof in advance; provided, however, that nothing contained in this agreement shall in any way limit the Fund's right to file at any time such amendments to any registration statement and/or supplements to any prospectus, of whatever character, as the Fund may deem advisable, such right being in all respects absolute and unconditional.

1.9 The Fund authorizes you to use any prospectus in the form furnished to you from time to time, in connection with the sale of Shares. The Fund agrees to indemnify, defend and hold you, your several officers and directors, and any person who controls you within the meaning of Section 15 of the Securities Act of 1933, as amended, free and harmless from and against any and all claims, demands, liabilities and expenses (including the cost of investigating or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which you, your officers and directors, or any such controlling person, may incur under the Securities Act of 1933, as amended, or under common law or otherwise, arising out of or based upon any untrue statement, or alleged untrue statement, of a material fact contained in any registration statement or any prospectus or arising out of or based upon any omission, or alleged omission, to state a material fact required to be stated in either any registration statement or any prospectus or necessary to make the statements in either thereof not misleading; provided, however, that the Fund's agreement to indemnify you, your officers or directors, and any such controlling person shall not be deemed to cover any claims, demands, liabilities or expenses arising out of any untrue statement or alleged untrue statement or omission or alleged omission made in any registration statement or prospectus in reliance upon and in conformity with written information furnished to the Fund by you specifically for use in the preparation thereof. The Fund's agreement to indemnify you, your officers and directors, and any such controlling person, as aforesaid, is expressly conditioned upon the Fund's being notified of any action brought against you, your officers or directors, or any such controlling person, such notification to be given by letter or by telegram addressed to the Fund at its address set forth above within ten days after the summons or other first legal process shall have been served. The failure so to notify the Fund of any such action shall not relieve the Fund from any liability which the Fund may have to the person against whom such action is brought by reason of any such untrue, or alleged untrue, statement or omission, or alleged omission, otherwise than on account of the Fund's indemnity agreement contained in this paragraph
1.9. The Fund will be entitled to assume the defense of any suit brought to enforce any such claim, demand or liability, but, in such case, such defense shall be conducted by counsel of good standing chosen by the Fund and approved by you. In the event the Fund elects to assume the defense of any such suit and retain counsel of good standing approved by you, the defendant or defendants in such suit shall bear the fees and expenses of any additional counsel retained by any of them; but in case the Fund does not elect to assume the defense of any such suit, or in case you do not approve of counsel chosen by the Fund, the Fund will reimburse you, your officers and directors, or the controlling person or persons named as defendant or defendants in such suit, for the fees and expenses of any counsel retained by you or them. The Fund's indemnification agreement contained in this paragraph 1.9 and the Fund's representations and warranties in this agreement shall remain operative and in full force and effect regardless of any investigation made by or on behalf of you, your officers and directors, or any controlling person, and shall survive the delivery of any Shares. This agreement of indemnity will inure exclusively to your benefit, to the benefit of your several officers and directors, and their respective estates, and to the benefit of any controlling persons and their successors. The Fund agrees promptly to notify you of the commencement of any litigation or proceedings against the Fund or any of its officers or Board members in connection with the issue and sale of Shares.

1.10 You agree to indemnify, defend and hold the Fund, its several officers and Board members, and any person who controls the Fund within the meaning of Section 15 of the Securities Act of 1933, as amended, free and harmless from and against any and all claims, demands, liabilities and expenses (including the cost of investigating or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which the Fund, its officers or Board members, or any such controlling person, may incur under the Securities Act of 1933, as amended, or under common law or otherwise, but only to the extent that such liability or expense incurred by the Fund, its officers or Board members, or such controlling person resulting from such claims or demands, shall arise out of or be based upon any untrue, or alleged untrue, statement of a material fact contained in information furnished in writing by you to the Fund specifically for use in the Fund's registration statement and used in the answers to any of the items of the registration statement or in the corresponding statements made in the prospectus, or shall arise out of or be based upon any omission, or alleged omission, to state a material fact in connection with such information furnished in writing by you to the Fund and required to be stated in such answers or necessary to make such information not misleading. Your agreement to indemnify the Fund, its officers and Board members, and any such controlling person, as aforesaid, is expressly conditioned upon your being notified of any action brought against the Fund, its officers or Board members, or any such controlling person, such notification to be given by letter or telegram addressed to you at your address set forth above within ten days after the summons or other first legal process shall have been served. You shall have the right to control the defense of such action, with counsel of your own choosing, satisfactory to the Fund, if such action is based solely upon such alleged misstatement or omission on your part, and in any other event the Fund, its officers or Board members, or such controlling person shall each have the right to participate in the defense or preparation of the defense of any such action. The failure so to notify you of any such action shall not relieve you from any liability which you may have to the Fund, its officers or Board members, or to such controlling person by reason of any such untrue, or alleged untrue, statement or omission, or alleged omission, otherwise than on account of your indemnity agreement contained in this paragraph 1.10. This agreement of indemnity will inure exclusively to the Fund's benefit, to the benefit of the Fund's officers and Board members, and their respective estates, and to the benefit of any controlling persons and their successors.

You agree promptly to notify the Fund of the commencement of any litigation or proceedings against you or any of your officers or directors in connection with the issue and sale of Shares.

1.11 No Shares shall be offered by either you or the Fund under any of the provisions of this agreement and no orders for the purchase or sale of such Shares hereunder shall be accepted by the Fund if and so long as the effectiveness of the registration statement then in effect or any necessary amendments thereto shall be suspended under any of the provisions of the Securities Act of 1933, as amended, or if and so long as a current prospectus as required by Section 10 of said Act, as amended, is not on file with the Securities and Exchange Commission; provided, however, that nothing contained in this paragraph 1.11 shall in any way restrict or have an application to or bearing upon the Fund's obligation to repurchase any Shares from any shareholder in accordance with the provisions of the Fund's prospectus or charter documents.

1.12 The Fund agrees to advise you immediately in writing:

(a) of any request by the Securities and Exchange Commission for amendments to the registration statement or prospectus then in effect or for additional information;

(b) in the event of the issuance by the Securities and Exchange Commission of any stop order suspending the effectiveness of the registration statement or prospectus then in effect or the initiation of any proceeding for that purpose;

(c) of the happening of any event which makes untrue any statement of a material fact made in the registration statement or prospectus then in effect or which requires the making of a change in such registration statement or prospectus in order to make the statements therein not misleading; and

(d) of all actions of the Securities and Exchange Commission with respect to any amendments to any registration statement or prospectus which may from time to time be filed with the Securities and Exchange Commission.

2. Offering Price

Shares of any class of the Fund offered for sale by you shall be offered for sale at a price per share (the "offering price") approximately equal to (a) their net asset value (determined in the manner set forth in the Fund's charter documents) plus (b) a sales charge, if any and except to those persons set forth in the then-current prospectus, which shall be the percentage of the offering price of such Shares as set forth in the Fund's then-current prospectus. The offering price, if not an exact multiple of one cent, shall be adjusted to the nearest cent. In addition, Shares of any class of the Fund offered for sale by you may be subject to a contingent deferred sales charge as set forth in the Fund's then-current prospectus. You shall be entitled to receive any sales charge or contingent deferred sales charge in respect of the Shares. Any payments to dealers shall be governed by a separate agreement between you and such dealer and the Fund's then-current prospectus.

3. Term

This agreement shall continue until the date (the "Reapproval Date") set forth on Exhibit A hereto (and, if the Fund has Series, a separate Reapproval Date shall be specified on Exhibit A for each Series), and thereafter shall continue automatically for successive annual periods ending on the day (the "Reapproval Day") of each year set forth on Exhibit A hereto, provided such continuance is specifically approved at least annually by (i) the Fund's Board or (ii) vote of a majority (as defined in the Investment Company Act of 1940) of the Shares of the Fund or the relevant Series, as the case may be, provided that in either event its continuance also is approved by a majority of the Board members who are not "interested persons" (as defined in said Act) of any party to this agreement, by vote cast in person at a meeting called for the purpose of voting on such approval. This agreement is terminable without penalty, on 60 days' notice, (a) by vote of holders of a majority of the Fund's or, as to any relevant Series, such Series' outstanding voting securities, or (b) by the Fund's Board as to the Fund or the relevant Series, as the case may be, or (c) by you. This agreement also will terminate automatically, as to the Fund or relevant Series, as the case may be, in the event of its assignment (as defined in said Act).

4. Miscellaneous

4.1 The Fund recognizes that from time to time your directors, officers, and employees may serve as trustees, directors, partners, officers, and employees of other business trusts, corporations, partnerships, or other entities (including other investment companies) and that such other entities may include the name "Dreyfus" as part of their name, and that your corporation or its affiliates may enter into distribution or other agreements with such other entities. If you cease to act as the distributor of the Fund's shares or if The Dreyfus Corporation ceases to act as the Fund's investment adviser, the Fund agrees that, at the request of The Dreyfus Corporation, the Fund will take all necessary action to change the name of the Fund to a name not including "Dreyfus" in any form or combination of words.

4.2 This agreement has been executed on behalf of the Fund by the undersigned officer of the Fund in his or her capacity as an officer of the Fund. The obligations of this agreement shall only be binding upon the assets and property of the Fund and shall not be binding upon any Board member, officer or shareholder of the Fund individually.

Please confirm that the foregoing is in accordance with your understanding and indicate your acceptance hereof by signing below, whereupon it shall become a binding agreement between us.

Very truly yours,
