                                SERIES HIGHLIGHTS
    

       The following summary is intended to highlight certain information
  contained in this Prospectus and is qualified in its entirety by the more
  detailed information appearing elsewhere herein.

  WHAT IS PRUDENTIAL INSTITUTIONAL LIQUIDITY PORTFOLIO, INC.?

   
       Prudential Institutional Liquidity Portfolio, Inc. is a mutual fund whose
  shares are offered in two series, each of which operates as a separate fund. A
  mutual fund pools the resources of investors by selling its shares to the
  public and investing the proceeds of such sale in a portfolio of securities
  designed to achieve its investment objective. Technically, the Fund is an
  open-end, diversified, management investment company. Only Class A shares of
  the Series are offered through this Prospectus.
    

  WHAT IS THE SERIES' INVESTMENT OBJECTIVE?

   
       The Series' investment objective is high current income consistent with
  the preservation of principal and liquidity. The Series invests primarily in a
  portfolio of U.S. Government obligations, financial institution obligations
  and other high quality money market instruments maturing in thirteen months or
  less. There can be no assurance that the Series' investment objective will be
  achieved. See "How the Series Invests--Investment Objective and Policies" at
  page 6.

  WHAT ARE THE SERIES' RISK FACTORS AND SPECIAL CHARACTERISTICS?

       It is anticipated that the net asset value of the Series will remain
  constant at $1.00 per share, although this cannot be assured. In order to
  maintain such constant net asset value, the Series will value its portfolio
  securities at amortized cost. While this method provides certainty in
  valuation, it may result in periods during which the value of a security in
  the Series' portfolio, as determined by amortized cost, is higher or lower
  than the price the Series would receive if it sold such security. See "How the
  Series Values its Shares" at page 13.

       The Series may invest in foreign securities without limit. Investing in
  securities of foreign companies and countries involves certain considerations
  and risks not typically associated with investing in securities of domestic
  companies. See "How the Series Invests--Investment Objective and
  Policies--Risks of Investing in Foreign Securities" at page 8.
    

  WHO MANAGES THE FUND?

   
       Prudential Investments Fund Management LLC (PIFM or the Manager) is the
  Manager of the Series and is currently compensated for its services at an
  annual rate of .15 of 1% of the Series' average daily net assets. As of April
  30, 1998, PIFM served as manager or administrator to 65 investment companies,
  including 43 mutual funds, with aggregate assets of approximately $64.8
  billion. The Prudential Investment Corporation (PIC), doing business as
  Prudential Investments (PI, the Subadviser or the investment adviser),
  furnishes investment advisory services in connection with the management of
  the Series under a Subadvisory Agreement with PIFM. See "How the Series is
  Managed--Manager" at page 11.

<PAGE>

  WHO DISTRIBUTES THE SERIES' SHARES?


   
       Until July 1, 1998, Prudential Securities Incorporated (Prudential
  Securities), a major securities underwriter and securities and commodities
  broker, will continue to act as the Distributor of the Series' shares. On and
  after July 1, 1998, Prudential Investment Management Services LLC will act as
  Distributor. Prudential Securities and Prudential Investment Management
  Services LLC are each referred to as the Distributor. The Series currently
  reimburses the Distributor for expenses related to the distribution of the
  Series' Class A shares at an annual rate of up to .05 of 1% of the average
  daily net assets of the Class A shares of the Series. See "How the Series is
  Managed--Distributor" at page 12.
    

  WHAT IS THE MINIMUM INVESTMENT?

   
       The minimum initial investment for Class A shares of the Series is
  $100,000. A master account and its subaccounts, as well as related
  institutional accounts (i.e., accounts of shareholders with a common
  institutional or corporate parent), in the Series may be aggregated for this
  minimum investment purpose. The minimum subsequent investment for Class A
  shares is $10,000. The Series reserves the right to impose a higher or lower
  minimum subsequent amount from time to time as it may deem appropriate. Class
  A shares of the Series are also available to corporate participants in the
  COMMAND(SM) Account program (the COMMAND Program), which is available through
  Prudential Securities Incorporated, and participants in the Prudential
  BusinessEdge(SM) Account Program (the BusinessEdge Program), which is
  available through either Prudential Securities Incorporated or Pruco
  Securities Corporation. See "Shareholder Guide--How to Buy Shares of the
  Series" at page 16 and "Shareholder Guide--Shareholder Services" at page 19.
    

  HOW DO I PURCHASE SHARES?

   
       You may purchase shares of the Series through Prudential Securities,
  Pruco Securities Corporation (Prusec) or directly from the Fund, through its
  transfer agent, Prudential Mutual Fund Services LLC (PMFS or the Transfer
  Agent), at the net asset value per share (NAV) next determined after receipt
  of your purchase order by the Transfer Agent or the Distributor. To open an
  account, a completed application form must be received by PMFS. See "How the
  Series Values its Shares" at page 13 and "Shareholder Guide--How to Buy Shares
  of the Series" at page 16.
    

  HOW DO I SELL MY SHARES?

   
       You may redeem shares of the Series at any time at the NAV next
  determined after the Transfer Agent or the Distributor receives your sell
  order. See "Shareholder Guide--How to Sell Your Shares" at page 17.
    

  HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?

   
       The Series expects to declare daily and pay monthly dividends of net
  investment income and short-term capital gains, if any. Dividends and
  distributions will be automatically reinvested in additional shares of the
  Series at NAV unless you request that they be paid to you in cash. See "Taxes,
  Dividends and Distributions--Dividends and Distributions" at page 15.

  You would pay the following expenses on a $1,000 investment, assuming 
   (1) 5% annual return and (2) redemption at the end of each time period:
   Class A .................................................................    $2      $7      $13       $29

  The above example is based on restated data for the Series' fiscal year ended
  March 31, 1998. The example should not be considered a representation of past
  or future expenses. Actual expenses may be greater or less than those shown.


  The purpose of the table is to assist an investor in understanding the various
  costs and expenses that an investor in the Series will bear, whether directly
  or indirectly. For more complete descriptions of the various costs and
  expenses, see "How the Series is Managed." "Other Expenses" includes operating
  expenses of the Series, such as Directors' and professional fees, registration
  fees, reports to shareholders and transfer agency and custodian fees.

- ----------
   
  *  In accordance with an interpretive position taken by the staff of the
     Securities and Exchange Commission, the annual program fee is reflected in
     the fee table. The annual program fee as a percentage of average net assets
     is calculated by dividing $125 (the total fee for the COMMAND Program) or
     $250 (the total for the BusinessEdge Program), respectively, by the average
     account size in the Series. The annual program fee is not prorated for
     purposes of this calculation to give effect to COMMAND Program or
     BusinessEdge Program participants who also own shares in or subscribe to
     various services offered by the respective Programs. A major portion of the
     annual program fee is not attributable to the Series, but rather to
     non-fund services provided by the Program. The fee table reflects the
     percentage of average net assets of the corporate COMMAND program. The fee
     for BusinessEdge, expressed as a percentage of average daily net assets,
     would be .06%.

  ** Based on expenses incurred during the fiscal year ended March 31, 1998,
     taking into account the management and distribution fee waiver and the
     Manager's expense subsidy which became effective June 2, 1997 for the
     entire fiscal year. For the fiscal year ended March 31, 1999, the Manager
     has agreed to limit its management fee with respect to Class A shares of
     the Series, and the Distributor has agreed to limit its distribution fees
     with respect to the Class A shares of the Series, to .15% and .05%,
     respectively, of the average daily net assets of the Class A shares. The
     Manager has also agreed to subsidize Other Expenses for the fiscal year
     ended March 31, 1999. Without the management and distribution fee waivers
     and the expense subsidy, Management Fees, 12b-1 Fees and Total Series
     Operating Expenses would be .20%, .12% and .41%, respectively, of the
     average daily net assets of the Series' Class A shares. See "How the Series
     is Managed--Distributor--Fee Waivers."

                              CALCULATION OF YIELD

   
     THE SERIES CALCULATES ITS "CURRENT YIELD" based on the net change,
exclusive of realized and unrealized capital gains or losses, in the value of a
hypothetical account over a seven calendar day base period. THE SERIES ALSO
CALCULATES ITS "EFFECTIVE ANNUAL YIELD" assuming weekly compounding. The
following is an example of the current and effective annual yield calculations
as of March 31, 1998:

CLASS A SHARES
- --------------
Value of hypothetical account at end of period ..............       $1.001058176
Value of hypothetical account at beginning of period ........        1.000000000
                                                                    ------------
Base period return ..........................................       $ .001058176
                                                                    ============
CURRENT YIELD (.001058176 x (365/7)) ........................              5.52%
EFFECTIVE ANNUAL YIELD, assuming weekly compounding .........              5.67%
    

     THE YIELD WILL FLUCTUATE FROM TIME TO TIME AND DOES NOT INDICATE FUTURE
PERFORMANCE.

   
     The weighted average life to maturity of the Series on March 31, 1998 was
76 days.

     Yield is computed in accordance with a standardized formula described in
the Statement of Additional Information. In addition, comparative performance
information may be used from time to time in advertising or marketing the shares
of the Series, including data from Lipper Analytical Services, Inc., Morningstar
Publications, Inc., IBC Financial Data, Inc., The Bank Rate Monitor, and other
industry publications, business periodicals and market indices.

                             HOW THE SERIES INVESTS
    

INVESTMENT OBJECTIVE AND POLICIES

   
     THE INVESTMENT OBJECTIVE OF THE SERIES IS HIGH CURRENT INCOME CONSISTENT
WITH THE PRESERVATION OF PRINCIPAL AND LIQUIDITY. THE SERIES PURSUES ITS
INVESTMENT OBJECTIVE THROUGH THE INVESTMENT POLICIES DESCRIBED BELOW. THERE CAN
BE NO ASSURANCE THAT THIS INVESTMENT OBJECTIVE WILL BE ACHIEVED.
    

     THE SERIES' INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE,
MAY NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE
SERIES' OUTSTANDING VOTING SECURITIES, AS DEFINED IN THE INVESTMENT COMPANY ACT
OF 1940, AS AMENDED (THE INVESTMENT COMPANY ACT). THE SERIES' POLICIES THAT ARE
NOT FUNDAMENTAL MAY BE MODIFIED BY THE BOARD OF DIRECTORS.

     THE ASSETS OF THE SERIES WILL BE INVESTED IN HIGH QUALITY MONEY MARKET
INSTRUMENTS MATURING IN THIRTEEN MONTHS OR LESS, AND THE DOLLAR-WEIGHTED AVERAGE
MATURITY OF THE PORTFOLIO OF THE SERIES WILL BE 90 DAYS OR LESS. The Series also
may hold cash reserves as the investment adviser deems necessary for temporary
defensive purposes.

   
     In selecting portfolio securities for investment by the Series, the
investment adviser considers ratings assigned by major rating services,
information concerning the financial history and condition of the issuer and its
revenue and expense prospects. The Board of Directors monitors the credit
quality of securities purchased for the Series' portfolio. If a portfolio
security held by the Series is assigned a lower rating or ceases to be rated,
the investment adviser under the supervision of the Board of Directors will
promptly reassess whether that security presents minimal credit risks and
whether the Series should continue to hold the security. If a portfolio security
no longer presents minimal credit risks or is in default, the Series will
dispose of the security as soon as reasonably practicable unless the investment
adviser determines that to do so is not in the best interest of the Series and
its shareholders.
    


                                       6

<PAGE>

   
     The Series utilizes the amortized cost method of valuation in accordance
with regulations of the Securities and Exchange Commission (SEC). See "How the
Fund Values its Shares." Accordingly, the Series will limit its portfolio
investments to those instruments which present minimal credit risks and which
are of "eligible quality," as determined by the Fund's investment adviser under
the supervision of the Board of Directors. "Eligible quality," for this purpose,
means (i) a security rated in one of the two highest rating categories by at
least two nationally recognized statistical rating organizations (e.g., Standard
& Poor's Rating Group or Moody's Investors Service) assigning a rating to the
security or issuer (or, if only one such rating organization assigned a rating,
that rating organization) or (ii) an unrated security deemed of comparable
quality by the Series' investment adviser under the supervision of the Board of
Directors.

     As long as the Series utilizes the amortized cost method of valuation, it
will also comply with certain diversification requirements and will invest no
more than 5% of its total assets in "second-tier securities," with no more than
1% of the Series' assets in any one issuer of a second-tier security. A
"second-tier security," for this purpose, is a security of "eligible quality"
that does not have the highest rating from at least two rating organizations
assigning a rating to that security or issuer (or, if only one rating
organization assigned a rating, that rating organization) or an unrated security
that is deemed of comparable quality by the Series' investment adviser under the
supervision of the Fund's Board of Directors.
    

     THE SERIES WILL INVEST AT LEAST 80%, AND GENERALLY NOT LESS THAN 100%, OF
ITS ASSETS IN HIGH QUALITY U.S. DOLLAR-DENOMINATED MONEY MARKET OBLIGATIONS OF
DOMESTIC AND FOREIGN ISSUERS AND U.S. GOVERNMENT AND FINANCIAL INSTITUTION
OBLIGATIONS DESCRIBED BELOW. There is no limitation on the percentage of the
Series' assets that may be invested in each of these categories. In addition,
the Series may utilize the investment techniques described below under "Other
Investments and Policies."

     U.S. GOVERNMENT OBLIGATIONS. The Series may invest in obligations issued or
guaranteed as to principal and interest by the U.S. Government or its agencies
or instrumentalities.

     U.S. TREASURY OBLIGATIONS. The Series may invest in U.S. Treasury
obligations, including bills, notes, bonds and other debt obligations issued by
the U.S. Treasury. These instruments are direct obligations of the U.S.
Government and, as such, are backed by the "full faith and credit" of the United
States. They differ primarily in their interest rates, the lengths of their
maturities and the dates of their issuances.

     OBLIGATIONS ISSUED OR GUARANTEED BY U.S. GOVERNMENT AGENCIES AND
INSTRUMENTALITIES AND THIRD PARTIES. The Series may also invest in obligations
issued by agencies of the U.S. Government or instrumentalities established or
sponsored by the U.S. Government. These obligations, including those which are
guaranteed by federal agencies or instrumentalities, may or may not be backed by
the full faith and credit of the United States. Obligations of the Government
National Mortgage Association (GNMA), the Farmers Home Administration and the
Small Business Administration are backed by the full faith and credit of the
United States. In the case of obligations not backed by the full faith and
credit of the United States, the Series must look principally to the agency
issuing or guaranteeing the obligation for ultimate repayment and may not be
able to assert a claim against the United States if the agency or
instrumentality does not meet its commitments. Instruments in which the Series
may invest which are not backed by the full faith and credit of the United
States include obligations issued by the Federal Home Loan Banks, the Federal
Home Loan Mortgage Corporation (FHLMC), the Federal National Mortgage
Association (FNMA), the Resolution Funding Corporation, the Student Loan
Marketing Association, and the Tennessee Valley Authority, each of which has the
right to borrow under certain circumstances from the U.S. Treasury to meet its
obligations, and obligations of the Farm Credit System, the obligations of which
may be satisfied only by the individual credit of the issuing agency. The
Series' investment in mortgage-backed securities (e.g., GNMA, FNMA and FHLMC
certificates) will be made only to the extent such securities are used as
collateral for repurchase agreements entered into by the Series.

     The Series may invest in component parts of U.S. Treasury notes or bonds,
namely, either the corpus (principal) of such Treasury obligations or one of the
interest payments scheduled to be paid on such obligations. See "Investment


                                       7

<PAGE>

Objectives and Policies--Obligations Issued or Guaranteed by the U.S.
Government, its Agency and Instrumentalities and Third Parties" in the Statement
of Additional Information.

     ASSET-BACKED SECURITIES. The Series may invest in asset-backed securities.
Asset-backed securities include interests in pools of mortgages, loans,
receivables, or other assets. Payment of principal and interest may be largely
dependent upon the cash flows generated by assets backing the securities.

     FINANCIAL INSTITUTION OBLIGATIONS. The Series may invest in obligations
(including certificates of deposit and bankers' acceptances) which are issued or
guaranteed by commercial banks, savings banks and savings and loan associations
whose total assets at the time of investment are more than $1 billion or its
equivalent. The term "certificates of deposit" includes both Eurodollar
certificates of deposit, for which there is generally a market, and Eurodollar
time deposits, for which there is generally not a market. Eurodollars are U.S.
dollars deposited in branches of banks outside the United States.

   
     OTHER MONEY MARKET INSTRUMENTS. The Series may invest in commercial paper,
variable amount demand master notes, funding agreements, bills, notes and other
obligations issued by a U.S. company, a foreign company or foreign governments,
their agencies and instrumentalities, maturing in thirteen months or less,
denominated in U.S. dollars, which, at the date of investment, are of "eligible
quality" as defined above. If such obligations are guaranteed or supported by a
letter of credit issued by a bank, such bank (including a foreign bank) must
meet the requirements set forth above under "Financial Institution Obligations."
If such obligations are guaranteed or insured by an insurance company or other
non-bank entity, such insurance company or other non-bank entity must represent
a credit of comparable quality, as determined by the Fund's investment adviser
under the supervision of the Fund's Board of Directors. In the case of
instruments issued by foreign companies or governments, the Series will only
invest in instruments which are not currently subject to foreign withholding
taxes.
    

     RISKS OF INVESTING IN FOREIGN SECURITIES. There is no limitation on the
percentage of the Series' assets that may be invested in foreign securities.
Since the portfolio of the Series may contain obligations of foreign issuers, an
investment in the Series involves certain risks. These risks include future
political and economic developments in the country of the issuer, the possible
imposition of withholding taxes on interest income payable on such obligations
held by the Series, the possible seizure or nationalization of foreign deposits
and the possible establishment of exchange controls or other foreign
governmental laws or restrictions which might affect adversely the payment of
principal and interest on such obligations held by the Series. In addition,
there may be less publicly available information about a foreign issuer than
about a domestic issuer, and such issuers may not be subject to the same
accounting, auditing and financial recordkeeping standards and requirements as
domestic issuers. Securities issued by foreign issuers may be subject to greater
fluctuations in price than securities issued by U.S. entities. Finally, in the
event of a default with respect to any such foreign debt obligations, it may be
more difficult for the Fund to obtain or to enforce a judgment against the
issuers of such securities.

   
RATING OF SERIES SHARES
    

     Duff & Phelps Credit Rating Co. (DCR) has given the Series an AAA rating.
According to DCR, the AAA rating means the Series' ability to meet redemption
requests in a timely manner for $1.00 per share is strong. This rating is based
on the Series' risk management procedures, internal control systems, limitations
on market risk and experienced management team.

OTHER INVESTMENTS AND POLICIES

LIQUIDITY PUTS

     The Series may purchase instruments of the types described above together
with the right to resell the instruments to brokers, dealers or financial
institutions at an agreed-upon price or yield within a specified period prior to
the maturity date of the instruments. Such a right to resell is commonly known
as a "put," and the aggregate price that the Series pays for instruments with a
put may be higher than the price that otherwise would be paid for the
instruments. Puts may


                                       8

<PAGE>

be exercised prior to the expiration date in order to fund obligations to
purchase other securities or meet redemption requests.

     Since the value of the put is dependent on the ability of the put writer to
meet its obligation to repurchase, the Series' policy is to enter into put
transactions only with such brokers, dealers or financial institutions which
present minimal credit risks. There is a credit risk associated with the
purchase of puts in that the broker, dealer or financial institution might
default on its obligation to repurchase an underlying security. Changes in the
credit quality of these institutions could cause losses to the Series and affect
its share price. In the event such a default should occur, the Fund is unable to
predict whether all or any portion of any loss sustained could subsequently be
recovered from the broker, dealer or financial institution.

FLOATING RATE AND VARIABLE RATE SECURITIES

     The Series may purchase "floating rate" and "variable rate" obligations.
The interest rates on such obligations fluctuate generally with changes in
market interest rates, and in some cases, the Series is able to demand repayment
of the principal amount of such obligations at par plus accrued interest. For
additional information concerning variable rate and floating rate obligations,
see "Investment Objective and Policies" in the Statement of Additional
Information.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

   
     The Series may purchase securities on a "when-issued" or delayed delivery
basis. When-issued or delayed delivery transactions arise when securities are
purchased or sold by the Series with payment and delivery taking place in the
future in order to secure what is considered to be an advantageous price and
yield to the Series at the time of entering into the transaction. The Series
will limit such purchases to those in which the date for delivery and payment
falls within 90 days of the date of the commitment. The Series will make
commitments for such when-issued transactions only with the intention of
actually acquiring the securities. The Series' Custodian will maintain, in a
segregated account of the Series, cash or other liquid assets having a value
equal to or greater than the Series' purchase commitments. If the Series chooses
to dispose of the right to acquire a when-issued security prior to its
acquisition, it could, as with the disposition of any other portfolio security,
incur a gain or loss due to market fluctuations. The securities so purchased are
subject to market fluctuation and no interest accrues to the purchaser during
the period between purchase and settlement.
    

PLEDGING OF ASSETS AND BORROWING

     The Series may borrow (including through entering into reverse repurchase
agreements) up to 15% of the value of its total assets (computed at the time the
loan is made) from banks for temporary, extraordinary or emergency purposes. The
Series may pledge up to 15% of its total assets to secure such borrowings. The
Series will not purchase portfolio securities if its borrowings exceed 5% of its
net assets.

REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS

   
     The Series may purchase securities and concurrently enter into "repurchase
agreements" with the seller, whereby the seller agrees to repurchase such
securities at a specified price within a specified time (generally seven days or
less). Repurchase agreements will only be entered into with member banks of the
Federal Reserve System or primary reporting dealers in U.S. Government
obligations and will be fully secured only by obligations permitted by the
Series' investment policies. The repurchase agreements provide that the Series
will sell the underlying instruments back to the dealer or the bank at the
specified price and at a fixed time in the future, usually not more than seven
days from the date of purchase. The difference between the purchase price and
the resale price represents the interest earned by the Series, which is
unrelated to the coupon rate or maturity of the purchased security. Repurchase
agreements will at all times be fully collateralized in an amount at least equal
to the resale price. Such collateral will be held by the Series' Custodian,
either physically or in a book-entry account.

     The Series will enter into repurchase transactions only with parties which
meet creditworthiness standards approved by the Fund's Board of Directors. The
Series' investment adviser monitors the creditworthiness of such parties under
the
    


                                       9

<PAGE>

general supervision of the Board of Directors. In the event of a default or
bankruptcy by a seller, the Series will promptly seek to liquidate the
collateral. To the extent that the proceeds from any sale of such collateral
upon a default in the obligation to repurchase are less than the resale price,
the Series will suffer a loss. If the financial institution that is a party to
the repurchase agreement petitions for bankruptcy or becomes subject to the U.S.
Bankruptcy Code, the law regarding the rights of the Fund is unsettled. As a
result, under these extreme circumstances, there may be a restriction on the
Series' ability to sell the collateral, and the Series could suffer a loss.

   
     Reverse repurchase agreements have the characteristics of borrowing and
involve the sale of securities held by the Series with an agreement to
repurchase the securities at a specified price, date and interest payment. The
Series intends only to use the reverse repurchase technique when it will be to
its advantage to do so. These transactions are only advantageous if the Series
has an opportunity to earn a greater rate of interest on the cash derived from
the transaction than the interest cost of obtaining that cash. The Series may be
unable to realize earnings from the use of the proceeds equal to or greater than
the interest required to be paid. The use of reverse repurchase agreements may
exaggerate any increase or decrease in the value of the Series' portfolio. The
Series' Custodian will maintain in a segregated account cash or other liquid
assets, maturing not later than the expiration of the reverse repurchase
agreements and having a value equal to or greater than such commitments.
    


ILLIQUID SECURITIES

   
     The Series may hold up to 10% of its net assets in illiquid securities
(determined at the time of the transaction), including securities with legal or
contractual restrictions on resale (restricted securities), securities that are
not readily marketable in securities markets either within or outside of the
United States, privately placed commercial paper and repurchase agreements which
have a maturity of longer than seven days. Restricted securities eligible for
resale pursuant to Rule 144A under the Securities Act of 1933, as amended (the
Securities Act), and privately placed commercial paper that have a readily
available market are not considered illiquid for purposes of this limitation.
The investment adviser will monitor the liquidity of such restricted securities
under the supervision of the Board of Directors. Investing in Rule 144A
securities could, however, have the effect of increasing illiquidity to the
extent that qualified institutional buyers become, for a limited time,
uninterested in purchasing these securities. Repurchase agreements subject to
demand are deemed to have a maturity equal to the applicable notice period. See
"Investment Objective and Policies--Illiquid Securities" in the Statement of
Additional Information.
    

SECURITIES OF OTHER INVESTMENT COMPANIES

     The Series may invest in the securities of other money market funds
registered under the Investment Company Act. See "Investment Objective and
Policies--Securities of Other Investment Companies" in the Statement of
Additional Information.

SUITABILITY FOR INVESTORS

     The Series is designed as an economic and convenient vehicle for those
institutional and high net worth individual investors seeking to obtain the
yields available from money market instruments while maintaining liquidity. The
Series is designed particularly for banks and other depositary institutions
seeking investment of short-term monies held in accounts for which the
institutions act in fiduciary, advisory, agency, custodial or other similar
capacities. The Series may be equally suitable for the investment of short-term
funds held or managed by corporations, employee benefit plans and others, if
consistent with the objectives of the particular account and any applicable
state and federal laws and regulations. The Series can arrange for special
processing to assist banks and other institutions desiring to establish multiple
accounts. See "Shareholder Guide--Shareholder Services--Subaccounting and
Special Services."

     The Series offers the advantages of large purchasing power and
diversification. Generally, in purchasing money market instruments from dealers,
the percentage difference between the bid and asked prices tends to decrease as
the size of the transaction increases. In addition, yields on short-term money
market instruments generally tend to increase as maturities are extended. Thus,
when yields on longer-term money market instruments are higher than yields on
shorter-term money market instruments, ownership of Series shares may allow an
investor to obtain the advantages of short-term liquidity and the higher yields
available from the Series' holdings of longer-term instruments. This benefit


                                       10

<PAGE>

will be reduced to the extent of the Series' expenses and may be unavailable
during periods when interest rates are higher for money market instruments with
maturities shorter than the weighted average maturity of the Series. The Series
also offers investors the opportunity to participate in a portfolio of money
market instruments which is more diversified in terms of issuers and maturities
than the investor's individual investment might otherwise permit.

     Investment in the Series relieves investors of many management and
administrative burdens usually associated with the direct purchase and sale of
money market instruments. These include selection of portfolio investments;
surveying the market for the best terms at which to buy and sell; scheduling and
monitoring maturities and reinvestments; receipt, delivery and safekeeping of
securities; and portfolio recordkeeping.

INVESTMENT RESTRICTIONS

     The Series is subject to certain investment restrictions which, like its
investment objective, constitute fundamental policies. Fundamental policies
cannot be changed without the approval of the holders of a majority of the
Series' outstanding voting securities, as defined in the Investment Company Act.

DISTRIBUTOR

   
     PRUDENTIAL SECURITIES INCORPORATED (PRUDENTIAL SECURITIES OR THE
DISTRIBUTOR), ONE SEAPORT PLAZA, NEW YORK, NEW YORK 10292, IS A CORPORATION
ORGANIZED UNDER THE LAWS OF THE STATE OF DELAWARE AND, UNTIL JULY 1, 1998,
SERVES AS THE SERIES' DISTRIBUTOR. IT IS AN INDIRECT, WHOLLY-OWNED SUBSIDIARY OF
PRUDENTIAL. ON JULY 1, 1998, PRUDENTIAL INVESTMENT MANAGEMENT SERVICES LLC
(DISTRIBUTOR), THREE GATEWAY CENTER, 100 MULBERRY STREET, NEWARK, NEW JERSEY
07102-4077, WILL BEGIN ACTING AS THE FUND'S DISTRIBUTOR. PRUDENTIAL INVESTMENT
MANAGEMENT SERVICES LLC IS A LIMITED LIABILITY COMPANY ORGANIZED UNDER THE LAWS
OF THE STATE OF DELAWARE AND IT IS A DIRECT WHOLLY-OWNED SUBSIDIARY OF
PRUDENTIAL.

     UNDER A DISTRIBUTION AND SERVICE PLAN (THE PLAN) ADOPTED BY THE FUND UNDER
RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT AND A DISTRIBUTION AND SERVICE
AGREEMENT (THE DISTRIBUTION AGREEMENT), THE DISTRIBUTOR INCURS THE EXPENSES OF
DISTRIBUTING THE SERIES' CLASS A SHARES. These expenses include account
servicing fees paid to, or on account of, financial advisers of Prudential
Securities and representatives of Pruco Securities Corporation (Prusec), an
affiliated broker-dealer, account servicing fees paid to, or on account of,
other broker-dealers or financial institutions (other than national banks) which
have entered into agreements with the Distributor, advertising expenses, the
cost of printing and mailing prospectuses to potential investors and indirect
and overhead costs of the Distributor, Prudential Securities and Prusec
associated with the sale of Class A shares of the Series, including lease,
utility, communications and sales promotion expenses.

     UNDER THE PLAN, THE SERIES REIMBURSES THE DISTRIBUTOR FOR ITS
DISTRIBUTION-RELATED EXPENSES AT AN ANNUAL RATE OF UP TO .12 OF 1% OF THE
AVERAGE DAILY NET ASSETS OF THE SERIES' CLASS A SHARES. Account servicing fees
are paid based on the average balance of the Class A shares of the Series held
in the accounts of the customers of financial advisers. The entire distribution
fee may be used to pay account servicing fees.

     For the fiscal year ended March 31, 1998, the Series paid a distribution
fee equal on an annual basis to .08% of the average daily net assets of the
Series' Class A shares. The Series records all payments made under the Plan as
expenses of the Class A shares in the calculation of the net investment income
of the Class A shares.

     For an indefinite period of time and until further notice, the Distributor
has agreed to waive .07 of 1% of its distribution fee. The Series is not
required to reimburse PSI for such distribution fee waiver.

     The Plan provides that it shall continue in effect from year to year
provided that each such continuance is approved annually by a majority vote of
the Board of Directors of the Fund, including a majority of the Directors who
are not interested persons of the Fund and who have no direct or indirect
financial interest in the operation of the Plan or any agreements related to the
Plan (the Rule 12b-1 Directors). The Board of Directors is provided with and
reviews quarterly reports of expenditures under the Plan. The Plan may be
terminated at any time by vote of a majority of the Rule 12b-1 Directors or a
majority of the outstanding Class A shares of the Series. The Series will not be
obligated to pay distribution and service fees under a Plan if it is terminated
or not continued.
    

     In addition to distribution and service fees paid by the Series under the
Plan, the Manager (or one of its affiliates) may make payments out of its own
resources to dealers (including Prudential Securities) and other persons which
distribute shares of the Series. Such payments may be calculated by reference to
the net asset value of shares sold by such persons or otherwise.

   
FEE WAIVERS

     For an indefinite period of time, and until further notice, the Manager has
agreed to waive .05 of 1% of its management fee and subsidize expenses and the
Distributor has agreed to waive up to .07 of 1% of its distribution/service fee.
The Series is not required to reimburse the Manager or the Distributor for such
management fee waiver or distribution fee waiver, respectively. Thereafter, the
Manager may from time to time agree to waive all or a portion of its management
fee and subsidize certain operating expenses of the Series. Fee waivers and
expense subsidies will increase the Series' yield and total return for so long
as such waivers and subsidies remain in place. The fee waivers and expense
subsidies may be discontinued at any time. See "Series Expenses."

PORTFOLIO TRANSACTIONS

   
     Prudential Securities or an affiliate of the Distributor may act as broker
for the Series, provided that the commissions, fees or other remuneration it
receives are fair and reasonable. See "Portfolio Transactions and Brokerage" in
the Statement of Additional Information.
    

CUSTODIAN AND TRANSFER AND SHAREHOLDER SERVICING AGENT

     State Street Bank and Trust Company (State Street), One Heritage Drive,
North Quincy, Massachusetts 02171, serves as Custodian for the Series' portfolio
securities and cash and, in that capacity, maintains certain financial and
accounting books and records pursuant to an agreement with the Fund. Its mailing
address is P.O. Box 1713, Boston, Massachusetts 02105.

   
     Prudential Mutual Fund Services LLC (PMFS or the Transfer Agent), Raritan
Plaza One, Edison, New Jersey 08837, serves as Transfer Agent and as Shareholder
Servicing Agent and in those capacities maintains certain books and records for
the Series. PMFS is a wholly-owned subsidiary of PIFM. Its mailing address is
P.O. Box 15005, New Brunswick, New Jersey 08906-5005.

YEAR 2000

     The services provided to the Series and the shareholders by the Manager,
the Distributor, the Transfer Agent and the Custodian depend on the smooth
functioning of their computer systems and those of their outside service
providers. Many computer software systems in use today cannot distinguish the
year 2000 from the year 1900 because of the way dates are encoded and
calculated. Such event could have a negative impact on handling securities
trades, payments of interest and dividends, pricing and account services.
Although, at this time, there can be no assurance that there will be no adverse
impact on the Series, the Manager, the Distributor, the Transfer Agent and the
Custodian have advised the Series that they have been actively working on
necessary changes to their computer systems to prepare for the year 2000 and
expect that their systems, and those of their outside service providers, will be
adapted in time for that event.
    

                        HOW THE SERIES VALUES ITS SHARES

   
     THE SERIES' NET ASSET VALUE PER SHARE OR NAV IS DETERMINED BY SUBTRACTING
ITS LIABILITIES FROM THE VALUE OF ITS ASSETS AND DIVIDING THE REMAINDER BY THE
NUMBER OF OUTSTANDING SHARES. THE BOARD OF DIRECTORS HAS FIXED THE SPECIFIC TIME
OF DAY FOR THE COMPUTATION OF THE NAV TO BE AS OF 4:00 P.M., NEW YORK TIME, ON
EACH DAY THE SERIES IS OPEN FOR BUSINESS.

     The Series is open each day that the New York Stock Exchange is open for
trading. The Fund reserves the right to reject any purchase order.
    

     It is the intention of the Series to maintain an NAV of $1.00, although
there can be no assurance that the Series will do so. The portfolio instruments
of the Series are valued on the basis of amortized cost valuation in accordance
with regulations issued by the SEC. 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 Series would receive if it sold the
instrument. The Fund's Board of Directors has established procedures designed to
stabilize, to the extent reasonably possible, the NAV of the shares of the
Series at $1.00 per share. See "Net Asset Value" in the Statement of Additional
Information.

                       TAXES, DIVIDENDS AND DISTRIBUTIONS

TAXATION OF THE SERIES

     THE SERIES HAS ELECTED TO QUALIFY AND INTENDS TO REMAIN QUALIFIED AS A
REGULATED INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED
(THE INTERNAL REVENUE CODE). ACCORDINGLY, THE SERIES WILL NOT BE SUBJECT TO
FEDERAL INCOME TAXES ON ITS NET INVESTMENT INCOME AND NET CAPITAL GAINS, IF ANY,
THAT IT DISTRIBUTES TO ITS SHAREHOLDERS PROVIDED THAT IT DISTRIBUTES TO
SHAREHOLDERS EACH YEAR AT LEAST 90% OF SUCH INCOME. If the Series defers until
the subsequent calendar year the distribution of more than a minimal amount of
income, it will be subject to a 4% nondeductible excise tax on the deferred
distribution. The Series intends to make timely and complete distributions in
order to avoid any such taxes.

TAXATION OF SHAREHOLDERS

     All dividends out of net investment income, together with distributions of
net short-term gains (i.e., the excess of net short-term capital gains over net
long-term capital losses), will be taxable to shareholders as ordinary income
whether or not reinvested. The Series does not anticipate realizing long-term
capital gains. However, to the extent the Series does recognize long-term
capital gains, the Series intends to declare capital gains distributions to the
extent of its net capital gains (i.e., the excess of net long-term capital gains
over net short-term capital losses). Capital gains distributions, if any, are
taxable to shareholders as net long-term capital gains, regardless of the length
of time a shareholder has owned its shares.

     It is anticipated that the net asset value per share of the Series will
remain constant. However, if the net asset value per share fluctuates, a
shareholder may realize gain or loss upon the disposition of a share.

   
     Any gain or loss realized upon a sale or redemption of shares by a
shareholder who is not a dealer in securities will be treated as long-term
capital gain or loss if the shares have been held more than one year and
otherwise as short-term capital gain or loss. Any such loss, however, although
otherwise treated as a short-term capital loss, will be treated as long-term
capital loss to the extent of any capital gain distributions received by the
shareholder, if the shares have been held for six months or less. The maximum
long-term capital gains rate for individual shareholders for securities held
between 12 and 18 months currently is 28% and for securities held more than 18
months is 20%. The maximum tax rate for individual shareholders for ordinary
income is 39.6%. The maximum long-term capital gains rate for corporate
shareholders is currently the same as the maximum tax rate for ordinary income.

     Dividends and distributions may be subject to state and local taxes.
Shareholders are advised to consult their own tax advisers regarding specific
questions as to federal, state or local taxes. See "Taxes, Dividends and
Distributions" in the Statement of Additional Information.
    

WITHHOLDING TAXES

   
     Under the Internal Revenue Code, the Series is required to withhold and
remit to the U.S. Treasury 31% of dividends, capital gain income and redemption
proceeds on the accounts of those shareholders who fail to furnish their tax
identification numbers on IRS Form W-9 (or IRS Form W-8 in the case of certain
foreign shareholders) with the required certifications regarding the
shareholder's status under the federal income tax law. However, dividends of net
investment income (and net short-term capital gains) paid to a foreign
shareholder will generally be subject to U.S. withholding tax at the rate of 30%
(or lower treaty rate).

     Shareholders are advised to consult their own tax advisers regarding
specific questions as to federal, state or local taxes. See "Taxes, Dividends
and Distributions" in the Statement of Additional Information.

<PAGE>

DIVIDENDS AND DISTRIBUTIONS

     NET INVESTMENT INCOME AND NET REALIZED SHORT-TERM CAPITAL GAINS, IF ANY, OF
THE SERIES WILL BE DECLARED AS A DIVIDEND DAILY IMMEDIATELY PRIOR TO THE
CALCULATION OF THE SERIES' NET ASSET VALUE AS OF 4:00 P.M., NEW YORK TIME. Net
investment income of the Series (from the time of the immediately preceding
declaration) consists of interest accrued or discount earned (including both
original issue and market discount) on the obligations in the Series, less
amortization of premium and the estimated expenses of the Series applicable to
that dividend period. The Series does not expect to realize long-term capital
gains or losses.

     The net investment income of the Series for dividend purposes is determined
on a daily basis. Each such dividend will be payable to shareholders of record
at the time of its declaration (including for this purpose holders of shares
purchased, but excluding holders of shares redeemed as of 4:00 P.M., New York
time, on that day). Dividends declared are accrued throughout the month and are
distributed in the form of full and fractional shares on or about the 23rd day
of the month, unless the shareholder elects in writing, not less than five
business days prior to the dividend distribution date, to receive such
distributions in cash. The dividend distribution date may be changed without
further notice to shareholders. Dividends are reinvested at the net asset value
determined as of 4:00 P.M., New York time, on the day of payment. If the entire
amount in an account is redeemed at any time during a month, all dividends
accrued with respect to that account during that month are paid to the investor
at the NAV as of 4:00 P.M., New York time, on the date of redemption.

   
     The calculation of net investment income for dividend purposes is made
immediately prior to the calculation of net asset value at 4:00 P.M., New York
time. If a purchase order and the funds for such purchase are received prior to
4:00 P.M., New York time, the shareholder begins to earn dividends declared on
that day.
    

     The Fund will not accept purchase and redemption orders after 4:00 P.M.,
New York time. If a redemption request is received prior to 4:00 P.M., New York
time, the shareholder does not earn a dividend on that day but the redemption
proceeds are wired on that day.

     Net income earned on Saturdays, Sundays and holidays is accrued in
calculating the dividend on the previous business day. Accordingly, an investor
who places a purchase order prior to 4:00 P.M., New York time, on a Friday
begins earning dividends that day. A shareholder which redeems its shares prior
to 4:00 P.M., New York time, on a Friday does not earn a dividend which reflects
the income earned by the Series on the Friday, or the following Saturday and
Sunday.

     Should the Series incur or anticipate any unusual expense or loss or
depreciation which would adversely affect its net asset value per share or
income for a particular period, the Board of Directors would at that time
consider whether to adhere to the present dividend policy described above or to
revise it in light of the then prevailing circumstances. For example, if the net
asset value per share of the Series is reduced, or is anticipated to be reduced,
below $1.00, the Board of Directors may suspend further dividend payments of the
Series until net asset value is returned to $1.00 per share. Thus, such expenses
or losses or depreciation could result in shareholders receiving no dividends
for the period during which they held their shares and in their receiving upon
redemption a price per share lower than that which they paid.

   
     The Fund has obtained an opinion of counsel to the effect that the exchange
of the Series' Class A shares for Class I shares does not constitute a taxable
event for federal income tax purposes. However, such opinion is not binding on
the Internal Revenue Service.
    

                               GENERAL INFORMATION

DESCRIPTION OF COMMON STOCK

     THE FUND WAS INCORPORATED IN MARYLAND ON SEPTEMBER 1, 1987. THE FUND IS
AUTHORIZED TO ISSUE 15 BILLION SHARES OF COMMON STOCK OF $.001 PAR VALUE WHICH
ARE CURRENTLY DIVIDED INTO TWO PORTFOLIOS OR SERIES. THE INSTITUTIONAL MONEY
MARKET SERIES HAS 10 BILLION AUTHORIZED SHARES AND THE LIQUID ASSETS SERIES HAS
5 BILLION AUTHORIZED SHARES.


                                       15

<PAGE>

   
OF THE 10 BILLION AUTHORIZED SHARES OF THE INSTITUTIONAL MONEY MARKET SERIES,
THERE ARE 5 BILLION AUTHORIZED CLASS A SHARES (WHICH CLASS INCLUDES SHARES
OUTSTANDING PRIOR TO JUNE 2, 1997) AND 5 BILLION AUTHORIZED CLASS I SHARES OF
THE SERIES, RESPECTIVELY. EACH CLASS REPRESENTS AN INTEREST IN THE SAME ASSETS
OF THE SERIES AND IS IDENTICAL IN ALL RESPECTS EXCEPT THAT (I) ONLY CLASS A
SHARES ARE SUBJECT TO DISTRIBUTION AND/OR SERVICE FEES, (II) EACH CLASS HAS
EXCLUSIVE VOTING RIGHTS ON ANY MATTER SUBMITTED TO SHAREHOLDERS THAT RELATES
SOLELY TO ITS ARRANGEMENT AND HAS SEPARATE VOTING RIGHTS ON ANY MATTER SUBMITTED
TO SHAREHOLDERS IN WHICH THE INTERESTS OF ONE CLASS DIFFER FROM THE INTERESTS OF
ANY OTHER CLASS AND (III) CLASS I SHARES ARE SUBJECT TO A HIGHER MINIMUM INITIAL
INVESTMENT AMOUNT.

     The Board of Directors may increase or decrease the aggregate number of
shares of common stock that the Fund has authority to issue. The Series does not
intend to issue stock certificates unless requested. Shares of the Series, when
issued, are fully paid, nonassessable, fully transferable and redeemable at the
option of the holder. Shares are also redeemable at the option of the Series
under certain circumstances as described under "Shareholder Guide-- How to Sell
Your Shares." All shares of the Series are equal as to earnings, assets and
voting privileges. There are no conversion, preemptive or other subscription
rights. In the event of liquidation, each share of common stock of the Series is
entitled to its portion of all of the Series' assets after all debt and expenses
of the Series have been paid. Because only Class A shares of the Series bear
distribution expenses, the liquidation proceeds to Class A shareholders would
likely be lower than to Class I shareholders. The Series' shares do not have
cumulative voting rights for the election of Directors. Pursuant to the Fund's
Articles of Incorporation, the Board of Directors may authorize the creation of
additional series and classes, with such preferences, privileges, limitations
and voting and dividend rights as the Board may determine.
    

     THE FUND DOES NOT INTEND TO HOLD ANNUAL SHAREHOLDER MEETINGS UNLESS
REQUIRED BY LAW. THE FUND WILL NOT BE REQUIRED TO HOLD ANNUAL MEETINGS OF
SHAREHOLDERS UNLESS, FOR EXAMPLE, THE ELECTION OF DIRECTORS IS REQUIRED TO BE
ACTED ON BY SHAREHOLDERS UNDER THE INVESTMENT COMPANY ACT. SHAREHOLDERS HAVE
CERTAIN RIGHTS, INCLUDING THE RIGHT TO CALL A MEETING UPON A VOTE OF 10% OF THE
FUND'S OUTSTANDING SHARES FOR THE PURPOSE OF VOTING ON THE REMOVAL OF ONE OR
MORE DIRECTORS OR TO TRANSACT ANY OTHER BUSINESS.

NUMBER (732) 417-7869).

     In order for shares to be redeemed and withdrawal proceeds to be wired on
the same day as the request is made, telephone instructions or the written
redemption request must be received by PMFS prior to 4:00 P.M., New York time.
Any request received prior to 4:00 P.M., New York time, will be wired the same
day. However, due to federal wire restrictions and individual bank hours of
operation, the proceeds may not be available to the client until the following
business day. Shares redeemed prior to 4:00 P.M., New York time, are not
entitled to income dividends declared on the day of redemption. See "Taxes,
Dividends and Distributions." Requests for redemptions of Series shares by
COMMAND Program participants must be submitted to their Prudential Securities
Financial Advisor, or by BusinessEdge Program participants to their Prudential
Securities Financial Advisor or Pruco Securities broker, by 2:00 P.M., New York
time.
    

     If a written request for redemption is submitted, the signatures on the
redemption request must be exactly as shown on the completed Application. If the
proceeds of the redemption (a) exceed $50,000, (b) are to be paid to a person

partnership, trust or fiduciary, the signature(s) on the redemption request and
on the certificates, if any, or stock power must be guaranteed by an "eligible
guarantor institution", and in the case of a corporate shareholder, a corporate
resolution must accompany the request. An "eligible guarantor institution"
includes any bank, broker, dealer or credit union. The Transfer Agent reserves
the right to request additional information from, and make reasonable inquiries
of, any eligible guarantor institution. For clients of Prusec, a signature
guarantee may be obtained from the agency or office manager of most Prudential
Insurance and Financial Services offices.


                                       17

<PAGE>

   
     In order to allow for the management of the Series with maximum
flexibility, you are urged to initiate redemptions of shares as early in the day
as possible and to notify the Series by at least 9:30 A.M., New York time, of
withdrawals in excess of $10 million.

     The Series reserves the right to withhold wiring redemption proceeds to
shareholders if, in the judgment of the investment adviser, the Series could be
adversely affected by making immediate payment, and may take up to seven days to
wire redemption proceeds. In making withdrawal requests, you must supply your
name(s), account number and personal identification number. Neither the Series
nor PMFS will be responsible for further verification of the authenticity of
telephoned instructions.
    

     You may change the bank account you have designated to receive amounts
withdrawn at any time by writing to PMFS with an appropriate signature guarantee
or by providing a certified copy of a corporate resolution authorizing the
change. Further documentation may be required when deemed appropriate by PMFS.

   
     REDEMPTION IN KIND. If the Board of Directors determines that it would be
detrimental to the best interests of the remaining shareholders of the Series to
make payment wholly or partly in cash, the Series may pay the redemption price
in whole or in part by a distribution in kind of securities from the investment
portfolio of the Series, in lieu of cash, in conformity with applicable rules of
the SEC. Securities will be readily marketable and will be valued in the same
manner as in a regular redemption. See "How the Series Values its Shares." If
your shares are redeemed in kind, you would incur transaction costs in
converting the assets into cash. The Series, however, has elected to be governed
by Rule 18f-1 under the Investment Company Act, pursuant to which the Series is
obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of
the net asset value of the Series during any 90-day period for any one
shareholder.

     INVOLUNTARY REDEMPTION. The Series reserves the right to redeem, upon 60
days' written notice, an account which is reduced by you because of a redemption
to a net asset value of less than $100,000. You may avoid this redemption by
increasing the net asset value of your account to $100,000 or more.
    

     The total value of a shareholder's investment in the Series at the time of
redemption may be more or less than his or her cost, depending on the value of
the securities held by the Series at such time and income earned.

     Under the Investment Company Act, the right of redemption may be suspended
or date of payment postponed at times when the New York Stock Exchange is closed
(other than customary weekend or holiday closings), trading on the New York
Stock Exchange is restricted, and under certain emergency or other circumstances
as determined by the SEC. In case of suspension of the right of redemption,
requests for redemption may be withdrawn or shareholders may receive payment
based on the net asset value determined next after the termination of the
suspension.

   
     AUTOMATIC REDEMPTION. Redemptions will be automatically effected by
Prudential Securities to satisfy debit balances arising under the COMMAND
Program or the BusinessEdge Program, such as those incurred by use of the
Visa(R) Gold Debit Card Account (for COMMAND Program) or the BusinessEdge
Visa(R) Debit Card Account (for BusinessEdge Program), including ATM transaction
purchases, cash advances and COMMAND Program or BusinessEdge Program Account
checks. The COMMAND Program or BusinessEdge Program Securities Account (the
Securities Account) will be automatically scanned for debits each business day
as of the close of business on that day. After application of any free credit
cash balances in the account to such debits, a sufficient number of shares of
the mutual fund selected by the participant that he or she has designated as his
or her primary fund for the investment of free credit cash balances (the Primary
Fund) will be redeemed as of that business day to satisfy any remaining debits
in the Securities Account and, if necessary, shares of other COMMAND Program or
BusinessEdge Program Account Funds, as applicable, owned by the Program
participant which have not been selected as his or her Primary Fund or shares of
a participant's money market funds managed by PIFM which are not Primary Funds
will be redeemed to satisfy debits in the Securities Account. Margin loans, if
available and selected under a Program, will be utilized to satisfy debits
remaining after the liquidation of all fund shares in a Securities Account, and
shares may not be purchased until all debits, margin loans and other
requirements in the Securities Account are satisfied. In the event of an
automatic redemption of shares, the participant will be entitled to dividends
declared on the redeemed shares through the business day preceding the day on
which the redemption is effective. Participants will not be entitled to
dividends declared on the date of redemption.

     MANUAL REDEMPTION. A shareholder investing through the COMMAND Program or
the BusinessEdge Program may redeem shares of the Series by submitting a written
request for redemption directly to the Distributor or by calling his or her
Prudential Securities Financial Advisor or Pruco Securities broker, as
applicable, who will submit the request to the Series' Transfer Agent. The
proceeds from a manual redemption will immediately become free credit cash
balances in the participant's Program Securities Account and will be
automatically invested in the Primary Fund selected as the participant's Primary
Fund. Redemption requests should not be sent to the Transfer Agent. If
inadvertently sent to the Transfer Agent, they will be forwarded to Prudential
Securities. The COMMAND Program and the BusinessEdge Program require the written
request to be signed by all persons in whose names the shares are registered,
exactly as their names appear on the Program Account Client Statement. In
certain instances, additional documents such as, but not limited to, trust
instruments, death certificates, appointments as executor or administrator or
certificates of corporate authority may be required.

     Under the COMMAND Program, Prudential Securities has the right to terminate
a Program Securities Account for any reason. Likewise, Prudential Securities or
Pruco Securities has the right to terminate a BusinessEdge Program Securities
Account for any reason. In either such event, all shares held in a shareholder's
account will be redeemed.

FREQUENT TRADING

     The Fund and the other Prudential Mutual Funds are not intended to serve as
vehicles for frequent trading in response to short-term fluctuations in the
market. Due to the disruptive effect that market timing investment strategies
and excessive trading can have on efficient portfolio management, the Fund
reserves the right to refuse purchase orders and exchanges by any person, group
or commonly controlled accounts, if, in the Manager's sole judgment, such
person, group or accounts were following a market timing strategy or were
otherwise engaging in excessive trading (Market Timers).

     To implement this authority to protect the Fund and its shareholders from
excessive trading, the Fund will reject all exchanges and purchases from a
Market Timer unless the Market Timer has entered into a written agreement with
the Fund or its affiliates pursuant to which the Market Timer has agreed to
abide by certain procedures, which include a daily dollar limit on trading. The
Fund may notify the Market Timer of rejection of an exchange or purchase order
subsequent to the day on which the order was placed.
    

     SHAREHOLDER SERVICES

     As a shareholder in the Series, you can take advantage of the following
additional services and privileges:

     o SHAREHOLDER INVESTMENT ACCOUNT. Upon the initial purchase of shares of
the Series, a Shareholder Investment Account is established for you under which
your shares are held by PMFS.

     PMFS maintains an account for you expressed in terms of full and fractional
shares of the Series rounded to the nearest 1/1000th of a share. All investments
in the Series are credited to your account in the form of shares immediately
upon acceptance and become entitled to dividends as described in "Taxes,
Dividends and Distributions." PMFS will also maintain subaccounts for investors.
See "Subaccounting and Special Services" below.

     Stock certificates are issued only upon your written request. PMFS will
provide a confirmation of all investments in or withdrawals from an account.
Within ten days after the end of each month, PMFS will send you a statement
setting forth a summary of the transactions in your account for the month and
the month-end balance of full and fractional shares held in the account.

     o SUBACCOUNTING AND SPECIAL SERVICES. Special processing can be arranged
with PMFS for corporations, banks and other institutions that wish to open
multiple accounts (a master account and subaccounts). An investor wishing to
avail itself of PMFS's subaccounting facilities or other special services for
individual or multiple accounts will be required to enter into a separate
agreement with PMFS. Charges for these services, if any, will be determined on
the basis of the level of services to be rendered. Subaccounts may be opened at
the time of the initial investment or at a later date.

     o EXCHANGE PRIVILEGE. The Fund does not currently offer an exchange
privilege for shares of the Series, except that Class A shareholders of the
Series who qualify to purchase Class I shares will have their Class A shares
exchanged for Class I shares on a quarterly basis.


                                       19

<PAGE>

     o REPORTS TO SHAREHOLDERS. The Fund will send you annual and semi-annual
reports. The financial statements appearing in the annual reports are audited by
independent accountants. In order to reduce duplicate mailing and printing
expenses, the Fund will provide one annual and semi-annual shareholder report
and annual prospectus per household. You may request additional copies of such
reports by calling (800) 225-1852 or by writing to the Fund at Gateway Center
Three, 100 Mulberry Street, Newark, New Jersey 07102-4077.

     o SHAREHOLDER INQUIRIES. Shareholder inquiries should be addressed to the
Fund at Gateway Center Three, 100 Mulberry Street, Newark, New Jersey

                         DESCRIPTION OF SECURITY RATINGS

MOODY'S INVESTORS SERVICE

BOND RATINGS

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

     Aa: Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than Aaa bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.

SHORT-TERM DEBT RATINGS

     Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations which have an original maturity not
exceeding one year.

     Prime-1: Issuers rated Prime-1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations.

     Prime-2: Issuers rated Prime-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations.

SHORT-TERM RATINGS

     VMIG-1: Variable rate short-term indebtedness rated "VMIG-1" is of the best
quality. There is present strong protection by established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing.

STANDARD & POOR'S RATINGS GROUP

BOND RATINGS

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

     AA: Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.

COMMERCIAL PAPER RATINGS

     An S&P commercial paper rating is a current assessment of the likelihood of
timely payment of debt considered short-term in the relevant market.

     A-1: This highest category indicates that the degree of safety regarding
timely payment is strong.

     A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated A-1.


                                      A-1

<PAGE>

DUFF & PHELPS CREDIT RATING CO.

LONG-TERM DEBT RATINGS

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

     AA: Bonds rated AA are considered to be of high credit quality. Protection
factors are strong. Risk is modest but may vary slightly from time to time
because of economic conditions.

SHORT-TERM DEBT RATINGS

     D-1+: Highest certainty of timely payment. Short-term liquidity, including
internal operating factors and/or access to alternative sources of funds, is
outstanding, and safety is just below risk-free U.S. Treasury short-term
obligations.

     D-1: Very high certainty of timely payment. Liquidity factors are excellent
and supported by good fundamental protection factors. Risk factors are minor.

     D-1-: High certainty of timely payment. Liquidity factors are strong and
supported by good fundamental protection factors. Risk factors are very small.

     D-2: Good certainty of timely payment. Liquidity factors and company
fundamentals are sound. Although ongoing funding needs may enlarge total
financing requirements, access to capital markets is good. Risk factors are
small.

FITCH INVESTORS SERVICES, L.P.

BOND RATINGS

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

     AA: Bonds considered to be investment grade and of very high credit
quality. The obligor's ability to pay interest and repay principal is very
strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated
in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable
future developments, short-term debt of these issuers is generally rated 'F-1+'.


SHORT-TERM DEBT RATINGS

     F-1+: Exceptionally Strong Credit Quality. Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

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

     F-2: Good Credit Quality. Issues assigned this rating have a satisfactory
degree of assurance for timely payment, but the margin of safety is not as great
as the 'F-1+' and 'F-1' categories.

                                SERIES HIGHLIGHTS

     The following summary is intended to highlight certain information
contained in this Prospectus and is qualified in its entirety by the more
detailed information appearing elsewhere herein.

WHAT IS PRUDENTIAL INSTITUTIONAL LIQUIDITY PORTFOLIO, INC.?

   
     Prudential Institutional Liquidity Portfolio, Inc. is a mutual fund whose
shares are offered in two series, each of which operates as a separate fund. A
mutual fund pools the resources of investors by selling its shares to the public
and investing the proceeds of such sale in a portfolio of securities designed to
achieve its investment objective. Technically, the Fund is an open-end,
diversified, management investment company. Only Class I shares of the Series
are offered through this Prospectus.
    

WHAT IS THE SERIES' INVESTMENT OBJECTIVE?

   
     The Series' investment objective is high current income consistent with the
preservation of principal and liquidity. The Series invests primarily in a
portfolio of U.S. Government obligations, financial institution obligations and
other high quality money market instruments maturing in thirteen months or less.
There can be no assurance that the Series' investment objective will be
achieved. See "How the Series Invests--Investment Objective and Policies" at
page 6. 

WHAT ARE THE SERIES' RISK FACTORS AND SPECIAL CHARACTERISTICS?

     It is anticipated that the net asset value of the Series will remain
constant at $1.00 per share, although this cannot be assured. In order to
maintain such constant net asset value, the Series will value its portfolio
securities at amortized cost. While this method provides certainty in valuation,
it may result in periods during which the value of a security in the Series'
portfolio, as determined by amortized cost, is higher or lower than the price
the Series would receive if it sold such security. See "How the Series Values
its Shares" at page 13.

     The Series may invest in foreign securities without limit. Investing in
securities of foreign companies and countries involves certain considerations
and risks not typically associated with investing in securities of domestic
companies. See "How the Series Invests--Investment Objective and Policies--Risks
of Investing in Foreign Securities" at page 8. 
    

WHO MANAGES THE FUND?


   
     Prudential Investments Fund Management LLC (PIFM or the Manager) is the
Manager of the Series and is currently compensated for its services at an annual
rate of .15 of 1% of the Series' average daily net assets. As of April 30, 1998,
PIFM served as manager or administrator to 65 investment companies, including 43
mutual funds, with aggregate assets of approximately $64.8 billion. The
Prudential Investment Corporation (PIC), doing business as Prudential
Investments (PI, the Subadviser or the investment adviser), furnishes investment
advisory services in connection with the management of the Series under a
Subadvisory Agreement with PIFM. See "How the Series is Managed--Manager" at
page 11. 
    


                                       2
<PAGE>

WHO DISTRIBUTES THE SERIES' SHARES?

   
     Until July 1 1998, Prudential Securities Incorporated (Prudential
Securities), a major securities underwriter and securities and commodities
broker, will continue to act as the Distributor of the Series' shares. On and
after July 1, 1998, Prudential Investment Management Services LLC will act as
Distributor. Prudential Securities and Prudential Investment Management Services
LLC are each referred to as the Distributor. The Distributor of Class I shares
incurs the expenses of distributing the Series' Class I shares from its own
resources under a Distribution Agreement with the Fund, none of which is
reimbursed by or paid for by the Series. See "How the Series is
Managed--Distributor" at page 12.
    

WHAT IS THE MINIMUM INVESTMENT?

   
     Class I shares of the Series are available for purchase with a minimum
initial investment of $5 million. A master account and its subaccounts, as well
as related institutional accounts (i.e., accounts of shareholders with a common
institutional or corporate parent), in the Series may be aggregated for this
minimum investment purpose. Subsequent investments in Class I shares must be
made in the amount of at least $10,000. The Series reserves the right to impose
a higher or lower subsequent minimum amount from time to time as it may deem
appropriate. See "Purchase of Shares" in the Statement of Additional
Information. Class I shares of the Series are also available to corporate
participants in the COMMANDsm Account program (the COMMAND Program), which is
available through Prudential Securities Incorporated, and participants in the
Prudential BusinessEdgesm Account Program (the BusinessEdge Program), which is
available through either Prudential Securities Incorporated or Pruco Securities
Corporation. See "Shareholder Guide--How to Buy Shares of the Series" at page 16
and "Shareholder Guide--Shareholder Services" at page 19.

     Class I shares may also be purchased by The Prudential Insurance Company of
America (Prudential), its subsidiaries and affiliates without the minimum
initial investment requirement.
    

HOW DO I PURCHASE SHARES?

   
     You may purchase shares of the Series through Prudential Securities, Pruco
Securities Corporation (Prusec) or directly from the Fund, through its transfer
agent, Prudential Mutual Fund Services LLC (PMFS or the Transfer Agent), at the
net asset value per share (NAV) next determined after receipt of your purchase
order by the Transfer Agent or the Distributor. To open an account, a completed
application form must be received by PMFS. See "How the Series Values its
Shares" at page 13 and "Shareholder Guide--How to Buy Shares of the Series"
at page 16. 
    

HOW DO I SELL MY SHARES?

   
     You may redeem shares of the Series at any time at the NAV next determined
after the Transfer Agent or the Distributor receives your sell order. See
"Shareholder Guide--How to Sell Your Shares" at page 16.
    

HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?

   
     The Series expects to declare daily and pay monthly dividends of net
investment income and short-term capital gains, if any. Dividends and
distributions will be automatically reinvested in additional shares of the
Series at NAV unless you request that they be paid to you in cash. See "Taxes,
Dividends and Distributions--Dividends and Distributions" at page 14.

You would pay the following expenses on a $1,000               
  investment, assuming (1) 5% annual return and                
  (2) redemption at the end of each time period:               
  Class I .....................................................   $2       $5

The above example is based on data for the Series' fiscal year ended March 31,
1998. The example should not be considered a representation of past or future
expenses. Actual expenses may be greater or less than those shown.

The purpose of the table is to assist an investor in understanding the various
costs and expenses that an investor in the Series will bear, whether directly or
indirectly. For more complete descriptions of the various costs and expenses,
see "How the Series is Managed." "Other Expenses" includes operating expenses of
the Series, such as Directors' and professional fees, registration fees, reports
to shareholders and transfer agency and custodian fees.
    
- ----------
   
 *   In accordance with an interpretive position taken by the staff of the
     Securities and Exchange Commission, the annual program fee is reflected in
     the fee table. The annual program fee as a percentage of average net assets
     is calculated by dividing $125 (the total fee for the COMMAND Program) or
     $250 (the total for the BusinessEdge Program), respectively, by the average
     account size in the Series. The annual program fee is not prorated for
     purposes of this calculation to give effect to COMMAND Program or
     BusinessEdge Program participants who also own shares in or subscribe to
     various services offered by the respective Programs. A major portion of the
     annual program fee is not attributable to the Series, but rather to
     non-fund services provided by the Program. The fee table reflects the
     percentage of average net assets of the Corporate COMMAND Program. The fee
     for BusinessEdge, expressed as a percentage of average daily net assets,
     would be 0%. 

**   Based on expenses expected to have been incurred if Class I shares had been
     in existence during the entire fiscal year ended March 31, 1998, taking
     into account the management fee waiver and the Manager's subsidy of other
     expenses. For the fiscal year ended March 31, 1999, the Manager has agreed
     to limit its management fee with respect to Class I shares of the Series to
     .15% of the average daily net assets of the Class I shares. The Manager has
     also agreed to subsidize Other Expenses for the fiscal year ended March 31,
     1999. Without the management fee waiver of .05 of 1% and the expense
     subsidy, Management Fees and Total Series Operating Expenses would be .20%
     and .30%, respectively, of the average daily net assets of the Series'
     Class I shares. See "How the Series is Managed--Distributor--Fee Waivers."

                              CALCULATION OF YIELD

   
     THE SERIES CALCULATES ITS "CURRENT YIELD" based on the net change,
exclusive of realized and unrealized capital gains or losses, in the value of a
hypothetical account over a seven calendar day base period. THE SERIES ALSO
CALCULATES ITS "EFFECTIVE ANNUAL YIELD" assuming weekly compounding. The
following is an example of the current and effective annual yield calculations
as of March 31, 1998:

    CLASS I SHARES
    --------------
    Value of hypothetical account at end of period .............   $1.001067773
    Value of hypothetical account at beginning of period .......    1.000000000
                                                                   ------------
    Base period return .........................................   $ .001067773
                                                                   ============
    CURRENT YIELD (.001067773 x (365/7)) .......................           5.57%
    EFFECTIVE ANNUAL YIELD, assuming weekly compounding ........           5.73%
    

     THE YIELD WILL FLUCTUATE FROM TIME TO TIME AND DOES NOT INDICATE FUTURE
PERFORMANCE.

   
     The weighted average life to maturity of the Series on March 31, 1998 was
76 days.

     Yield is computed in accordance with a standardized formula described in
the Statement of Additional Information. In addition, comparative performance
information may be used from time to time in advertising or marketing the shares
of the Series, including data from Lipper Analytical Services, Inc., Morningstar
Publications, Inc., IBC Financial Data, Inc., The Bank Rate Monitor, and other
industry publications, business periodicals and market indices.

                             HOW THE SERIES INVESTS
    

INVESTMENT OBJECTIVE AND POLICIES

   
     THE INVESTMENT OBJECTIVE OF THE SERIES IS HIGH CURRENT INCOME CONSISTENT
WITH THE PRESERVATION OF PRINCIPAL AND LIQUIDITY. THE SERIES PURSUES ITS
INVESTMENT OBJECTIVE THROUGH THE INVESTMENT POLICIES DESCRIBED BELOW. THERE CAN
BE NO ASSURANCE THAT THIS INVESTMENT OBJECTIVE WILL BE ACHIEVED.
    

     THE SERIES' INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE,
MAY NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE
SERIES' OUTSTANDING VOTING SECURITIES, AS DEFINED IN THE INVESTMENT COMPANY ACT
OF 1940, AS AMENDED (THE INVESTMENT COMPANY ACT). THE SERIES' POLICIES THAT ARE
NOT FUNDAMENTAL MAY BE MODIFIED BY THE BOARD OF DIRECTORS.

     THE ASSETS OF THE SERIES WILL BE INVESTED IN HIGH QUALITY MONEY MARKET
INSTRUMENTS MATURING IN THIRTEEN MONTHS OR LESS, AND THE DOLLAR-WEIGHTED AVERAGE
MATURITY OF THE PORTFOLIO OF THE SERIES WILL BE 90 DAYS OR LESS. The Series also
may hold cash reserves as the investment adviser deems necessary for temporary
defensive purposes.

   
     In selecting portfolio securities for investment by the Series, the
investment adviser considers ratings assigned by major rating services,
information concerning the financial history and condition of the issuer and its
revenue and expense prospects. The Board of Directors monitors the credit
quality of securities purchased for the Series' portfolio. If a portfolio
security held by the Series is assigned a lower rating or ceases to be rated,
the investment adviser under the supervision of the Board of Directors will
promptly reassess whether that security presents minimal credit risks and
whether the Series should continue to hold the security. If a portfolio security
no longer presents minimal credit risks or is in default, the Series will
dispose of the security as soon as reasonably practicable unless the investment
adviser determines that to do so is not in the best interest of the Series and
its shareholders.
    


                                       6

<PAGE>


   
     The Series utilizes the amortized cost method of valuation in accordance
with regulations of the Securities and Exchange Commission (SEC). See "How the
Fund Values its Shares." Accordingly, the Series will limit its portfolio
investments to those instruments which present minimal credit risks and which
are of "eligible quality," as determined by the Fund's investment adviser under
the supervision of the Board of Directors. "Eligible quality," for this purpose,
means (i) a security rated in one of the two highest rating categories by at
least two nationally recognized statistical rating organizations (e.g., Standard
& Poor's Rating Group or Moody's Investors Service) assigning a rating to the
security or issuer (or, if only one such rating organization assigned a rating,
that rating organization) or (ii) an unrated security deemed of comparable
quality by the Series' investment adviser under the supervision of the Board of
Directors.

     As long as the Series utilizes the amortized cost method of valuation, it
will also comply with certain diversification requirements and will invest no
more than 5% of its total assets in "second-tier securities," with no more than
1% of the Series' assets in any one issuer of a second-tier security. A
"second-tier security," for this purpose, is a security of "eligible quality"
that does not have the highest rating from at least two rating organizations
assigning a rating to that security or issuer (or, if only one rating
organization assigned a rating, that rating organization) or an unrated security
that is deemed of comparable quality by the Fund's investment adviser under the
supervision of the Series' Board of Directors.
    

     THE SERIES WILL INVEST AT LEAST 80%, AND GENERALLY NOT LESS THAN 100%, OF
ITS ASSETS IN HIGH QUALITY U.S. DOLLAR-DENOMINATED MONEY MARKET OBLIGATIONS OF
DOMESTIC AND FOREIGN ISSUERS AND U.S. GOVERNMENT AND FINANCIAL INSTITUTION
OBLIGATIONS DESCRIBED BELOW. There is no limitation on the percentage of the
Series' assets that may be invested in each of these categories. In addition,
the Series may utilize the investment techniques described below under "Other
Investments and Policies."

     U.S. GOVERNMENT OBLIGATIONS. The Series may invest in obligations issued or
guaranteed as to principal and interest by the U.S. Government or its agencies
or instrumentalities.

     U.S. TREASURY OBLIGATIONS. The Series may invest in U.S. Treasury
obligations, including bills, notes, bonds and other debt obligations issued by
the U.S. Treasury. These instruments are direct obligations of the U.S.
Government and, as such, are backed by the "full faith and credit" of the United
States. They differ primarily in their interest rates, the lengths of their
maturities and the dates of their issuances.

     OBLIGATIONS ISSUED OR GUARANTEED BY U.S. GOVERNMENT AGENCIES AND
INSTRUMENTALITIES AND THIRD PARTIES. The Series may also invest in obligations
issued by agencies of the U.S. Government or instrumentalities established or
sponsored by the U.S. Government. These obligations, including those which are
guaranteed by federal agencies or instrumentalities, may or may not be backed by
the full faith and credit of the United States. Obligations of the Government
National Mortgage Association (GNMA), the Farmers Home Administration and the
Small Business Administration are backed by the full faith and credit of the
United States. In the case of obligations not backed by the full faith and
credit of the United States, the Series must look principally to the agency
issuing or guaranteeing the obligation for ultimate repayment and may not be
able to assert a claim against the United States if the agency or
instrumentality does not meet its commitments. Instruments in which the Series
may invest which are not backed by the full faith and credit of the United
States include obligations issued by the Federal Home Loan Banks, the Federal
Home Loan Mortgage Corporation (FHLMC), the Federal National Mortgage
Association (FNMA), the Resolution Funding Corporation, the Student Loan
Marketing Association, and the Tennessee Valley Authority, each of which has the
right to borrow under certain circumstances from the U.S. Treasury to meet its
obligations, and obligations of the Farm Credit System, the obligations of which
may be satisfied only by the individual credit of the issuing agency. The
Series' investment in mortgage-backed securities (e.g., GNMA, FNMA and FHLMC
certificates) will be made only to the extent such securities are used as
collateral for repurchase agreements entered into by the Series.

     The Series may invest in component parts of U.S. Treasury notes or bonds,
namely, either the corpus (principal) of such Treasury obligations or one of the
interest payments scheduled to be paid on such obligations. See "Investment

Government, its Agency and Instrumentalities and Third Parties" in the Statement
of Additional Information.

     ASSET-BACKED SECURITIES. The Series may invest in asset-backed securities.
Asset-backed securities include interests in pools of mortgages, loans,
receivables, or other assets. Payment of principal and interest may be largely
dependent upon the cash flows generated by assets backing the securities.

     FINANCIAL INSTITUTION OBLIGATIONS. The Series may invest in obligations
(including certificates of deposit and bankers' acceptances) which are issued or
guaranteed by commercial banks, savings banks and savings and loan associations
whose total assets at the time of investment are more than $1 billion or its
equivalent. The term "certificates of deposit" includes both Eurodollar
certificates of deposit, for which there is generally a market, and Eurodollar
time deposits, for which there is generally not a market. Eurodollars are U.S.
dollars deposited in branches of banks outside the United States.

   
     OTHER MONEY MARKET INSTRUMENTS. The Series may invest in commercial paper,
variable amount demand master notes, funding agreements, bills, notes and other
obligations issued by a U.S. company, a foreign company or foreign governments,
their agencies and instrumentalities, maturing in thirteen months or less,
denominated in U.S. dollars, which, at the date of investment, are of "eligible
quality" as defined above. If such obligations are guaranteed or supported by a
letter of credit issued by a bank, such bank (including a foreign bank) must
meet the requirements set forth above under "Financial Institution Obligations."
If such obligations are guaranteed or insured by an insurance company or other
non-bank entity, such insurance company or other non-bank entity must represent
a credit of comparable quality, as determined by the Fund's investment adviser
under the supervision of the Fund's Board of Directors. In the case of
instruments issued by foreign companies or governments, the Series will only
invest in instruments which are not currently subject to foreign withholding
taxes.
    

     RISKS OF INVESTING IN FOREIGN SECURITIES. There is no limitation on the
percentage of the Series' assets that may be invested in foreign securities.
Since the portfolio of the Series may contain obligations of foreign issuers, an
investment in the Series involves certain risks. These risks include future
political and economic developments in the country of the issuer, the possible
imposition of withholding taxes on interest income payable on such obligations
held by the Series, the possible seizure or nationalization of foreign deposits
and the possible establishment of exchange controls or other foreign
governmental laws or restrictions which might affect adversely the payment of
principal and interest on such obligations held by the Series. In addition,
there may be less publicly available information about a foreign issuer than
about a domestic issuer, and such issuers may not be subject to the same
accounting, auditing and financial recordkeeping standards and requirements as
domestic issuers. Securities issued by foreign issuers may be subject to greater
fluctuations in price than securities issued by U.S. entities. Finally, in the
event of a default with respect to any such foreign debt obligations, it may be
more difficult for the Fund to obtain or to enforce a judgment against the
issuers of such securities. 

   
RATING OF SERIES SHARES
    

     Duff & Phelps Credit Rating Co. (DCR) has given the Series an AAA rating.
According to DCR, the AAA rating means the Series' ability to meet redemption
requests in a timely manner for $1.00 per share is strong. This rating is based
on the Series' risk management procedures, internal control systems, limitations
on market risk and experienced management team. 

OTHER INVESTMENTS AND POLICIES 

LIQUIDITY PUTS

     The Series may purchase instruments of the types described above together
with the right to resell the instruments to brokers, dealers or financial
institutions at an agreed-upon price or yield within a specified period prior to
the maturity date of the instruments. Such a right to resell is commonly known
as a "put," and the aggregate price that the Series pays for instruments with a
put may be higher than the price that otherwise would be paid for the
instruments. Puts may 


                                       8

<PAGE>

be exercised prior to the expiration date in order to fund
obligations to purchase other securities or meet redemption requests.

     Since the value of the put is dependent on the ability of the put writer to
meet its obligation to repurchase, the Series' policy is to enter into put
transactions only with such brokers, dealers or financial institutions which
present minimal credit risks. There is a credit risk associated with the
purchase of puts in that the broker, dealer or financial institution might
default on its obligation to repurchase an underlying security. Changes in the
credit quality of these institutions could cause losses to the Series and affect
its share price. In the event such a default should occur, the Fund is unable to
predict whether all or any portion of any loss sustained could subsequently be
recovered from the broker, dealer or financial institution.

FLOATING RATE AND VARIABLE RATE SECURITIES

     The Series may purchase "floating rate" and "variable rate" obligations.
The interest rates on such obligations fluctuate generally with changes in
market interest rates, and in some cases, the Series is able to demand repayment
of the principal amount of such obligations at par plus accrued interest. For
additional information concerning variable rate and floating rate obligations,
see "Investment Objective and Policies" in the Statement of Additional
Information.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

   
     The Series may purchase securities on a "when-issued" or delayed delivery
basis. When-issued or delayed delivery transactions arise when securities are
purchased or sold by the Series with payment and delivery taking place in the
future in order to secure what is considered to be an advantageous price and
yield to the Series at the time of entering into the transaction. The Series
will limit such purchases to those in which the date for delivery and payment
falls within 90 days of the date of the commitment. The Series will make
commitments for such when-issued transactions only with the intention of
actually acquiring the securities. The Series' Custodian will maintain, in a
segregated account of the Series, cash or other liquid assets having a value
equal to or greater than the Series' purchase commitments. If the Series chooses
to dispose of the right to acquire a when-issued security prior to its
acquisition, it could, as with the disposition of any other portfolio security,
incur a gain or loss due to market fluctuations. The securities so purchased are
subject to market fluctuation and no interest accrues to the purchaser during
the period between purchase and settlement. 
    

PLEDGING OF ASSETS AND BORROWING

     The Series may borrow (including through entering into reverse repurchase
agreements) up to 15% of the value of its total assets (computed at the time the
loan is made) from banks for temporary, extraordinary or emergency purposes. The
Series may pledge up to 15% of its total assets to secure such borrowings. The
Series will not purchase portfolio securities if its borrowings exceed 5% of its
net assets.

REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS

   
     The Series may purchase securities and concurrently enter into "repurchase
agreements" with the seller, whereby the seller agrees to repurchase such
securities at a specified price within a specified time (generally seven days or
less). Repurchase agreements will only be entered into with member banks of the
Federal Reserve System or primary reporting dealers in U.S. Government
obligations and will be fully secured only by obligations permitted by the
Series' investment policies. The repurchase agreements provide that the Series
will sell the underlying instruments back to the dealer or the bank at the
specified price and at a fixed time in the future, usually not more than seven
days from the date of purchase. The difference between the purchase price and
the resale price represents the interest earned by the Series, which is
unrelated to the coupon rate or maturity of the purchased security. Repurchase
agreements will at all times be fully collateralized in an amount at least equal
to the resale price. Such collateral will be held by the Series' Custodian,
either physically or in a book-entry account.

     The Series will enter into repurchase transactions only with parties which
meet creditworthiness standards approved by the Fund's Board of Directors. The
Series' investment adviser monitors the creditworthiness of such parties under
the 
    


                                       9
<PAGE>

general supervision of the Board of Directors. In the event of a default or
bankruptcy by a seller, the Series will promptly seek to liquidate the
collateral. To the extent that the proceeds from any sale of such collateral
upon a default in the obligation to repurchase are less than the resale price,
the Series will suffer a loss. If the financial institution that is a party to
the repurchase agreement petitions for bankruptcy or becomes subject to the U.S.
Bankruptcy Code, the law regarding the rights of the Fund is unsettled. As a
result, under these extreme circumstances, there may be a restriction on the
Series' ability to sell the collateral, and the Series could suffer a loss.

   
     Reverse repurchase agreements have the characteristics of borrowing and
involve the sale of securities held by the Series with an agreement to
repurchase the securities at a specified price, date and interest payment. The
Series intends only to use the reverse repurchase technique when it will be to
its advantage to do so. These transactions are only advantageous if the Series
has an opportunity to earn a greater rate of interest on the cash derived from
the transaction than the interest cost of obtaining that cash. The Series may be
unable to realize earnings from the use of the proceeds equal to or greater than
the interest required to be paid. The use of reverse repurchase agreements may
exaggerate any increase or decrease in the value of the Series' portfolio. The
Series' Custodian will maintain in a segregated account cash or other liquid
assets, maturing not later than the expiration of the reverse repurchase
agreements and having a value equal to or greater than such commitments.
    

ILLIQUID SECURITIES

   
     The Series may hold up to 10% of its net assets in illiquid securities
(determined at the time of transaction), including securities with legal or
contractual restrictions on resale (restricted securities), securities that are
not readily marketable in securities markets either within or outside of the
United States, privately placed commercial paper and repurchase agreements which
have a maturity of longer than seven days. Restricted securities eligible for
resale pursuant to Rule 144A under the Securities Act of 1933, as amended (the
Securities Act), and privately placed commercial paper that have a readily
available market are not considered illiquid for purposes of this limitation.
The investment adviser will monitor the liquidity of such restricted securities
under the supervision of the Board of Directors. Investing in Rule 144A
securities could, however, have the effect of increasing illiquidity to the
extent that qualified institutional buyers become, for a limited time,
uninterested in purchasing these securities. Repurchase agreements subject to
demand are deemed to have a maturity equal to the applicable notice period. See
"Investment Objective and Policies--Illiquid Securities in the Statement of
Additional Information.
    

SECURITIES OF OTHER INVESTMENT COMPANIES

     The Series may invest in the securities of other money market funds
registered under the Investment Company Act. See "Investment Objective and
Policies--Securities of Other Investment Companies" in the Statement of
Additional Information.

SUITABILITY FOR INVESTORS

     The Series is designed as an economic and convenient vehicle for those
institutional and high net worth individual investors seeking to obtain the
yields available from money market instruments while maintaining liquidity. The
Series is designed particularly for banks and other depositary institutions
seeking investment of short-term monies held in accounts for which the
institutions act in fiduciary, advisory, agency, custodial or other similar
capacities. The Series may be equally suitable for the investment of short-term
funds held or managed by corporations, employee benefit plans and others, if
consistent with the objectives of the particular account and any applicable
state and federal laws and regulations. The Series can arrange for special
processing to assist banks and other institutions desiring to establish multiple
accounts. See "Shareholder Guide--Shareholder Services--Subaccounting and
Special Services."

     The Series offers the advantages of large purchasing power and
diversification. Generally, in purchasing money market instruments from dealers,
the percentage difference between the bid and asked prices tends to decrease as
the size of the transaction increases. In addition, yields on short-term money
market instruments generally tend to increase as maturities are extended. Thus,
when yields on longer-term money market instruments are higher than yields on
shorter-term money market instruments, ownership of Series shares may allow an
investor to obtain the advantages of short-term liquidity and the higher yields
available from the Series' holdings of longer-term instruments. This benefit


                                       10

<PAGE>

will be reduced to the extent of the Series' expenses and may be unavailable
during periods when interest rates are higher for money market instruments with
maturities shorter than the weighted average maturity of the Series. The Series
also offers investors the opportunity to participate in a portfolio of money
market instruments which is more diversified in terms of issuers and maturities
than the investor's individual investment might otherwise permit.

     Investment in the Series relieves investors of many management and
administrative burdens usually associated with the direct purchase and sale of
money market instruments. These include selection of portfolio investments;
surveying the market for the best terms at which to buy and sell; scheduling and
monitoring maturities and reinvestments; receipt, delivery and safekeeping of
securities; and portfolio recordkeeping. 

INVESTMENT RESTRICTIONS

     The Series is subject to certain investment restrictions which, like its
investment objective, constitute fundamental policies. Fundamental policies
cannot be changed without the approval of the holders of a majority of the
Series' outstanding voting securities, as defined in the Investment Company Act.
See "Investment Restrictions" in the Statement of Additional Information.

   
                            HOW THE SERIES IS MANAGED

     THE FUND HAS A BOARD OF DIRECTORS WHICH, IN ADDITION TO OVERSEEING THE
ACTIONS OF THE SERIES' MANAGER, SUBADVISER AND DISTRIBUTOR, AS SET FORTH BELOW,
DECIDES UPON MATTERS OF GENERAL POLICY. THE SERIES' MANAGER CONDUCTS AND
SUPERVISES THE DAILY BUSINESS OPERATIONS OF THE SERIES. THE SERIES' SUBADVISER
FURNISHES DAILY INVESTMENT ADVISORY SERVICES.

     For the fiscal year ended March 31, 1998, total expenses for the Series'
Class I shares as a percentage of average net assets were .15%. See "Financial
Highlights." 
    

MANAGER

   
     PRUDENTIAL INVESTMENTS FUND MANAGEMENT LLC (PIFM OR THE MANAGER), GATEWAY
CENTER THREE, 100 MULBERRY STREET, NEWARK, NEW JERSEY 07102-4077, IS THE MANAGER
OF THE SERIES AND IS COMPENSATED FOR ITS SERVICES AT AN ANNUAL RATE OF UP TO.20
OF 1% OF THE AVERAGE DAILY NET ASSETS OF THE SERIES. PIFM is organized in New
York as a limited liability company. For the fiscal year ended March 31, 1998,
the Series paid management fees to PIFM of .15% of its average daily net assets.
See "Manager" in the Statement of Additional Information.

     As of April 30, 1998, PIFM served as the manager to 43 open-end investment
companies, constituting all of the Prudential Mutual Funds, and as manager or
administrator to 22 closed-end investment companies with aggregate assets of
approximately $64.8 billion.

     UNDER THE MANAGEMENT AGREEMENT WITH THE FUND, PIFM MANAGES THE INVESTMENT
OPERATIONS OF THE SERIES AND ALSO ADMINISTERS THE SERIES' CORPORATE AFFAIRS. See
"Manager" in the Statement of Additional Information.

     UNDER A SUBADVISORY AGREEMENT BETWEEN PIFM AND THE PRUDENTIAL INVESTMENT
CORPORATION (PIC), DOING BUSINESS AS PRUDENTIAL INVESTMENTS (PI, THE SUBADVISER
OR THE INVESTMENT ADVISER), PI FURNISHES INVESTMENT ADVISORY SERVICES IN
CONNECTION WITH THE MANAGEMENT OF THE SERIES AND IS REIMBURSED BY PIFM FOR ITS
REASONABLE COSTS AND EXPENSES INCURRED IN PROVIDING SUCH SERVICES. Under the
Management Agreement, PIFM continues to have responsibility for all investment
advisory services and supervises PI's performance of such services.
    

     PIFM and PIC are wholly-owned subsidiaries of The Prudential Insurance
Company of America (Prudential), a major diversified insurance and financial
services company.


                                       11

<PAGE>


DISTRIBUTOR

   
     PRUDENTIAL SECURITIES INCORPORATED (PRUDENTIAL SECURITIES OR THE
DISTRIBUTOR), ONE SEAPORT PLAZA, NEW YORK, NEW YORK 10292, IS A CORPORATION
ORGANIZED UNDER THE LAWS OF THE STATE OF DELAWARE AND, UNTIL APPROXIMATELY JULY
1, 1998, SERVES AS THE SERIES' DISTRIBUTOR. IT IS AN INDIRECT, WHOLLY-OWNED
SUBSIDIARY OF PRUDENTIAL. ON OR ABOUT JULY 1, 1998, PRUDENTIAL INVESTMENT
MANAGEMENT SERVICES LLC (DISTRIBUTOR), THREE GATEWAY CENTER, 100 MULBERRY
STREET, NEWARK, NEW JERSEY 07102-4077, WILL BEGIN ACTING AS THE FUND'S
DISTRIBUTOR. PRUDENTIAL INVESTMENT MANAGEMENT SERVICES LLC IS A LIMITED
LIABILITY COMPANY ORGANIZED UNDER THE LAWS OF THE STATE OF DELAWARE AND IS A
DIRECT WHOLLY-OWNED SUBSIDIARY OF PRUDENTIAL.

     The Distributor incurs the expenses of distributing the Series' Class I
shares from its own resources under a Distribution Agreement with the Fund, none
of which is reimbursed by or paid for by the Series.

     The Manager (or one of its affiliates) may make payments out of its own
resources to dealers (including Prudential Securities) and other persons which
distribute shares of the Series. Such payments may be calculated by reference to
the net asset value of shares sold by such persons or otherwise.
    

  FEE WAIVERS

   
     For an indefinite period of time, and until further notice, the Manager has
agreed to waive .05 of 1% of its management fee and subsidize expenses. The
Series is not required to reimburse the Manager for such management fee waiver.
Fee waivers and expense subsidies will increase the Series' yield and total
return for so long as such waivers and subsidies remain in place. The fee
waivers and expense subsidies may be discontinued at any time. See "Series
Expenses."
    

PORTFOLIO TRANSACTIONS

   
     Prudential Securities or an affiliate of the Distributor may act as broker
for the Series, provided that the commissions, fees or other remuneration it
receives are fair and reasonable. See "Portfolio Transactions and Brokerage" in
the Statement of Additional Information. 
    

CUSTODIAN AND TRANSFER AND SHAREHOLDER SERVICING AGENT

     State Street Bank and Trust Company (State Street), One Heritage Drive,
North Quincy, Massachusetts 02171, serves as Custodian for the Series' portfolio
securities and cash and, in that capacity, maintains certain financial and
accounting books and records pursuant to an agreement with the Fund. Its mailing
address is P.O. Box 1713, Boston, Massachusetts 02105.

   
     Prudential Mutual Fund Services LLC (PMFS or the Transfer Agent), Raritan
Plaza One, Edison, New Jersey 08837, serves as Transfer Agent and as Shareholder
Servicing Agent and in those capacities maintains certain books and records for
the Series. PMFS is a wholly-owned subsidiary of PIFM. Its mailing address is
P.O. Box 15005, New Brunswick, New Jersey 08906-5005.

YEAR 2000

     The services provided to the Series and the shareholders by the Manager,
the Distributor, the Transfer Agent and the Custodian depend on the smooth
functioning of their computer systems and those of their outside service
providers. Many computer software systems in use today cannot distinguish the
year 2000 from the year 1900 because of the way dates are encoded and
calculated. Such event could have a negative impact on handling securities
trades, payments of interest and dividends, pricing and account services.
Although, at this time, there can be no assurance that there will be no adverse
impact on the Series, the Manager, the Distributor, the Transfer Agent and the
Custodian have advised the Series that they have been actively working on
necessary changes to their computer systems to prepare for the year 2000 and
expect that their systems, and those of their outside service providers, will be
adapted in time for that event.


                                       12

<PAGE>

                        HOW THE SERIES VALUES ITS SHARES
    

     THE SERIES' NET ASSET VALUE PER SHARE OR NAV IS DETERMINED BY SUBTRACTING
ITS LIABILITIES FROM THE VALUE OF ITS ASSETS AND DIVIDING THE REMAINDER BY THE
NUMBER OF OUTSTANDING SHARES. THE BOARD OF DIRECTORS HAS FIXED THE SPECIFIC TIME
OF DAY FOR THE COMPUTATION OF THE NAV TO BE AS OF 4:00 P.M., NEW YORK TIME, ON
EACH DAY THE SERIES IS OPEN FOR BUSINESS.

   
     THE SERIES IS OPEN EACH DAY THAT THE NEW YORK STOCK EXCHANGE IS OPEN FOR
TRADING. The Fund reserves the right to reject any purchase order.
    

     It is the intention of the Series to maintain an NAV of $1.00, although
there can be no assurance that the Series will do so. The portfolio instruments
of the Series are valued on the basis of amortized cost valuation in accordance
with regulations issued by the SEC. 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 Series would receive if it sold the
instrument. The Fund's Board of Directors has established procedures designed to
stabilize, to the extent reasonably possible, the NAV of the shares of the
Series at $1.00 per share. See "Net Asset Value" in the Statement of Additional
Information.

                       TAXES, DIVIDENDS AND DISTRIBUTIONS

TAXATION OF THE SERIES

     THE SERIES HAS ELECTED TO QUALIFY AND INTENDS TO REMAIN QUALIFIED AS A
REGULATED INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED
(THE INTERNAL REVENUE CODE). ACCORDINGLY, THE SERIES WILL NOT BE SUBJECT TO
FEDERAL INCOME TAXES ON ITS NET INVESTMENT INCOME AND NET CAPITAL GAINS, IF ANY,
THAT IT DISTRIBUTES TO ITS SHAREHOLDERS PROVIDED THAT IT DISTRIBUTES TO
SHAREHOLDERS EACH YEAR AT LEAST 90% OF SUCH INCOME. If the Series defers until
the subsequent calendar year the distribution of more than a minimal amount of
income, it will be subject to a 4% nondeductible excise tax on the deferred
distribution. The Series intends to make timely and complete distributions in
order to avoid any such taxes.

TAXATION OF SHAREHOLDERS

     All dividends out of net investment income, together with distributions of
net short-term gains (i.e., the excess of net short-term capital gains over net
long-term capital losses), will be taxable to shareholders as ordinary income
whether or not reinvested. The Series does not anticipate realizing long-term
capital gains. However, to the extent the Series does recognize long-term
capital gains, the Series intends to declare capital gains distributions to the
extent of its net capital gains (i.e., the excess of net long-term capital gains
over net short-term capital losses). Capital gains distributions, if any, are
taxable to shareholders as net long-term capital gains, regardless of the length
of time a shareholder has owned its shares.

     It is anticipated that the net asset value per share of the Series will
remain constant. However, if the net asset value per share fluctuates, a
shareholder may realize gain or loss upon the disposition of a share.

   
     Any gain or loss realized upon a sale or redemption of shares by a
shareholder who is not a dealer in securities will be treated as long-term
capital gain or loss if the shares have been held more than one year and
otherwise as short-term capital gain or loss. Any such loss, however, although
otherwise treated as a short-term capital loss, will be treated as long-term
capital loss to the extent of any capital gain distributions received by the
shareholder, if the shares have been held for six months or less. The maximum
long-term capital gains rate for individual shareholders for securities held
    


                                       13

<PAGE>

   
between 12 and 18 months currently is 28% and for securities held more than 18
months is 20%. The maximum tax rate for individual shareholders for ordinary
income is 39.6%. The maximum long-term capital gains rate for corporate
shareholders is currently the same as the maximim tax rate for ordinary income.

     Dividends and distributions may be subject to state and local taxes.
Shareholders are advised to consult their own tax advisers regarding specific
questions as to federal, state or local taxes. See "Taxes, Dividends and
Distributions" in the Statement of Additional Information. 
    

WITHHOLDING TAXES

   
     Under the Internal Revenue Code, the Series is required to withhold and
remit to the U.S. Treasury 31% of dividends, capital gain income and redemption
proceeds on the accounts of those shareholders who fail to furnish their tax
identification numbers on IRS Form W-9 (or IRS Form W-8 in the case of certain
foreign shareholders) with the required certifications regarding the
shareholder's status under the federal income tax law. However, dividends of net
investment income (and net short-term capital gains) paid to a foreign
shareholder will generally be subject to U.S. withholding tax at the rate of 30%
(or lower treaty rate).

     Shareholders are advised to consult their own tax advisers regarding
specific questions as to federal, state or local taxes. See "Taxes, Dividends
and Distributions" in the Statement of Additional Information. 
    

DIVIDENDS AND DISTRIBUTIONS

     NET INVESTMENT INCOME AND NET REALIZED SHORT-TERM CAPITAL GAINS, IF ANY, OF
THE SERIES WILL BE DECLARED AS A DIVIDEND DAILY IMMEDIATELY PRIOR TO THE
CALCULATION OF THE SERIES' NET ASSET VALUE AS OF 4:00 P.M., NEW YORK TIME. Net
investment income of the Series (from the time of the immediately preceding
declaration) consists of interest accrued or discount earned (including both
original issue and market discount) on the obligations in the Series, less
amortization of premium and the estimated expenses of the Series applicable to
that dividend period. The Series does not expect to realize long-term capital
gains or losses.

     The net investment income of the Series for dividend purposes is determined
on a daily basis. Each such dividend will be payable to shareholders of record
at the time of its declaration (including for this purpose holders of shares
purchased, but excluding holders of shares redeemed as of 4:00 P.M., New York
time, on that day). Dividends declared are accrued throughout the month and are
distributed in the form of full and fractional shares on or about the 23rd day
of the month, unless the shareholder elects in writing, not less than five
business days prior to the dividend distribution date, to receive such
distributions in cash. The dividend distribution date may be changed without
further notice to shareholders. Dividends are reinvested at the net asset value
determined as of 4:00 P.M., New York time, on the day of payment. If the entire
amount in an account is redeemed at any time during a month, all dividends
accrued with respect to that account during that month are paid to the investor
at the NAV as of 4:00 P.M., New York time, on the date of redemption.

   
     The calculation of net investment income for dividend purposes is made
immediately prior to the calculation of net asset value at 4:00 P.M., New York
time. If a purchase order and the funds for such purchase are received prior
to4:00 P.M., New York time, the shareholder begins to earn dividends declared on
that day.
    

     The Fund will not accept purchase and redemption orders after 4:00 P.M.,
New York time. If a redemption request is received prior to 4:00 P.M., New York
time, the shareholder does not earn a dividend on that day but the redemption
proceeds are wired on that day.

     Net income earned on Saturdays, Sundays and holidays is accrued in
calculating the dividend on the previous business day. Accordingly, an investor
who places a purchase order prior to 4:00 P.M., New York time, on a Friday
begins earning dividends that day. A shareholder which redeems its shares prior
to 4:00 P.M., New York time, on a Friday does not earn a dividend which reflects
the income earned by the Series on the Friday, or the following Saturday and
Sunday.

     Should the Series incur or anticipate any unusual expense or loss or
depreciation which would adversely affect its net asset value per share or
income for a particular period, the Board of Directors would at that time
consider whether to adhere to the present dividend policy described above or to
revise it in light of the then prevailing circumstances. For


                                       14

<PAGE>

example, if the net asset value per share of the Series is reduced, or is
anticipated to be reduced, below $1.00, the Board of Directors may suspend
further dividend payments of the Series until net asset value is returned to
$1.00 per share. Thus, such expenses or losses or depreciation could result in
shareholders receiving no dividends for the period during which they held their
shares and in their receiving upon redemption a price per share lower than that
which they paid.

   
     The Fund has obtained an opinion of counsel to the effect that the exchange
of the Series' Class A shares for Class I shares does not constitute a taxable
event for federal income tax purposes. However, such opinion is not binding on
the Internal Revenue Service.
    

                              GENERAL INFORMATION

DESCRIPTION OF COMMON STOCK

   
     THE FUND WAS INCORPORATED IN MARYLAND ON SEPTEMBER 1, 1987. THE FUND IS
AUTHORIZED TO ISSUE 15 BILLION SHARES OF COMMON STOCK OF $.001 PAR VALUE WHICH
ARE CURRENTLY DIVIDED INTO TWO PORTFOLIOS OR SERIES. THE INSTITUTIONAL MONEY
MARKET SERIES HAS 10 BILLION AUTHORIZED SHARES AND THE LIQUID ASSETS SERIES HAS
5 BILLION AUTHORIZED SHARES. OF THE 10 BILLION AUTHORIZED SHARES OF THE
INSTITUTIONAL MONEY MARKET SERIES, THERE ARE 5 BILLION AUTHORIZED CLASS A SHARES
(WHICH CLASS INCLUDES SHARES OUTSTANDING PRIOR TO JUNE 2, 1997) AND 5 BILLION
AUTHORIZED CLASS I SHARES OF THE SERIES, RESPECTIVELY. EACH CLASS REPRESENTS AN
INTEREST IN THE SAME ASSETS OF THE SERIES AND IS IDENTICAL IN ALL RESPECTS
EXCEPT THAT (I) ONLY CLASS A SHARES ARE SUBJECT TO DISTRIBUTION AND/OR SERVICE
FEES, (II) EACH CLASS HAS EXCLUSIVE VOTING RIGHTS ON ANY MATTER SUBMITTED TO
SHAREHOLDERS THAT RELATES SOLELY TO ITS ARRANGEMENT AND HAS SEPARATE VOTING
RIGHTS ON ANY MATTER SUBMITTED TO SHAREHOLDERS IN WHICH THE INTERESTS OF ONE
CLASS DIFFER FROM THE INTERESTS OF ANY OTHER CLASS AND (III) CLASS I SHARES ARE
SUBJECT TO A HIGHER MINIMUM INITIAL INVESTMENT AMOUNT.

     The Board of Directors may increase or decrease the aggregate number of
shares of common stock that the Fund has authority to issue. The Series does not
intend to issue stock certificates unless requested. Shares of the Series, when
issued, are fully paid, nonassessable, fully transferable and redeemable at the
option of the holder. Shares are also redeemable at the option of the Series
under certain circumstances as described under "Shareholder Guide--How to Sell
Your Shares." All shares of the Series are equal as to earnings, assets and
voting privileges. There are no conversion, preemptive or other subscription
rights. In the event of liquidation, each share of common stock of the Series is
entitled to its portion of all of the Series' assets after all debt and expenses
of the Series have been paid. Because only Class A shares of the Series bear
distribution expenses, the liquidation proceeds to Class A Shareholders would
likely be lower than to Class I Shareholders. The Series' shares do not have
cumulative voting rights for the election of Directors. Pursuant to the Fund's
Articles of Incorporation, the Board of Directors may authorize the creation of
additional series and classes, with such preferences, privileges, limitations
and voting and dividend rights as the Board may determine.
    

     THE FUND DOES NOT INTEND TO HOLD ANNUAL SHAREHOLDER MEETINGS UNLESS
REQUIRED BY LAW. THE FUND WILL NOT BE REQUIRED TO HOLD ANNUAL MEETINGS OF
SHAREHOLDERS UNLESS, FOR EXAMPLE, THE ELECTION OF DIRECTORS IS REQUIRED TO BE
ACTED ON BY SHAREHOLDERS UNDER THE INVESTMENT COMPANY ACT. SHAREHOLDERS HAVE
CERTAIN RIGHTS, INCLUDING THE RIGHT TO CALL A MEETING UPON A VOTE OF 10% OF THE
FUND'S OUTSTANDING SHARES FOR THE PURPOSE OF VOTING ON THE REMOVAL OF ONE OR
MORE DIRECTORS OR TO TRANSACT ANY OTHER BUSINESS.

HOW TO BUY SHARES OF THE SERIES

   GENERAL INFORMATION

   
     Class I shares of the Series are available for purchase with a minimum
initial investment of $5 million. A master account and its subaccounts, as well
as related institutional accounts (i.e., accounts of shareholders with a common
institutional or corporate parent), in the Series may be aggregated for this
minimum investment purpose. Subsequent investments in Class I shares must be
made in the amount of at least $10,000. The Series reserves the right to impose
a higher or lower subsequent minimum amount from time to time as it may deem
appropriate. See "Purchase of Shares" in the Statement of Additional
Information.

     Class I shares may also be purchased by The Prudential Insurance Company of
America (Prudential), its subsidiaries and affiliates without the minimum
initial investment requirement.

     The Series does not intend to issue stock certificates unless requested.
The Series reserves the right to reject any purchase order or to suspend or
modify the continuous offering of its shares.

     Investments in the Series must be made via wire transfer of funds to State
Street Bank and Trust Company, Boston, Massachusetts, the Series' Custodian. To
open an account, the completed Application must be received by PMFS, the Fund's
shareholder servicing agent.
    

     If a purchase order is telephoned to PMFS (toll-free) (800-521-7466) before
4:00 P.M., New York time, and federal funds are received by the Custodian on
that business day, the purchase order becomes effective as of 4:00 P.M., New
York time, and the shares are entitled to dividend income earned on that day.
All account transactions by telephone through PMFS will be recorded.

   
     Purchase orders by COMMAND Program participants must be submitted to their
Prudential Securities Financial Advisor, or by BusinessEdge Program participants
to their Prudential Securities Financial Advisor or Pruco Securities broker, by
2:00 P.M., New York time.
    

     In order to make investments which will generate income immediately, the
Fund must have federal funds available to it. Therefore, investors who desire to
have their purchase orders become effective as of 4:00 P.M., New York time, are
urged to wire funds to the Custodian via the Federal Reserve Wire System as
early in the day as possible. 

HOW TO SELL YOUR SHARES

   
     YOU CAN REDEEM ALL OR ANY PART OF THE VALUE OF YOUR ACCOUNT ON ANY BUSINESS
DAY BY INSTRUCTING THE SERIES TO REDEEM YOUR SHARES AS DESCRIBED BELOW.
REDEMPTIONS MAY BE REQUESTED BY TELEPHONE AND ARE EFFECTED AT THE PER SHARE NET
ASSET VALUE NEXT DETERMINED AFTER RECEIPT OF THE REQUEST FOR REDEMPTION IN
PROPER FORM.

     PRUDENTIAL SECURITIES CLIENTS FOR WHOM PRUDENTIAL SECURITIES HAS PURCHASED
SHARES OF THE SERIES MAY HAVE THESE SHARES REDEEMED ONLY THROUGH PRUDENTIAL
SECURITIES. PLEASE CONTACT YOUR PRUDENTIAL SECURITIES FINANCIAL ADVISOR.

     YOU MUST DESIGNATE ON YOUR APPLICATION THE U.S. COMMERCIAL BANK ACCOUNT OR
PRUDENTIAL SECURITIES ACCOUNT INTO WHICH YOU WISH THE PROCEEDS OF WITHDRAWALS
FROM YOUR ACCOUNT IN THE SERIES DEPOSITED. YOU MAY WITHDRAW AN AMOUNT FROM YOUR
ACCOUNT IN THE SERIES BY INSTRUCTING PMFS TO HAVE THE PROCEEDS OF WITHDRAWAL

ACCOUNT. PMFS ACCEPTS WITHDRAWAL INSTRUCTIONS BY TELEPHONE AT (800) 521-7466
ONCE YOU IDENTIFY YOURSELF AS A PERSON AUTHORIZED ON THE COMPLETED APPLICATION
AND PROVIDE YOUR ACCOUNT NUMBER AND YOUR PERSONAL IDENTIFICATION NUMBER.

     DURING PERIODS OF SEVERE MARKET OR ECONOMIC CONDITIONS, THE TELEPHONE
REDEMPTION PRIVILEGE MAY BE DIFFICULT TO IMPLEMENT. IF YOU ARE UNABLE TO REACH
PMFS BY TELEPHONE, A REDEMPTION REQUEST MAY BE TELECOPIED TO PMFS (TELECOPIER
NUMBER (732) 417-7869).


                                       16

<PAGE>

     In connection with the sale of Class I shares, the Manager, the Distributor
or one of their affiliates may pay dealers, financial advisers and other persons
which distribute shares a finders' fee from its own resources based on a
percentage of the net asset value of shares sold by such persons.

     In order for shares to be redeemed and withdrawal proceeds to be wired on
the same day as the request is made, telephone instructions or the written
redemption request must be received by PMFS prior to 4:00 P.M., New York time.
Any request received prior to 4:00 P.M., New York time, will be wired the same
day. However, due to federal wire restrictions and individual bank hours of
operation, the proceeds may not be available to the client until the following
business day. Shares redeemed prior to 4:00 P.M., New York time, are not
entitled to income dividends declared on the day of redemption. See "Taxes,
Dividends and Distributions." Requests for redemptions of Series shares by
COMMAND Program participants must be submitted to their Prudential Securities
Financial Advisor, or by BusinessEdge Program participants to their Prudential
Securities Financial Advisor or Pruco Securities broker, by 2:00 P.M., New York
time.
    

     If a written request for redemption is submitted, the signatures on the
redemption request must be exactly as shown on the completed Application. If the
proceeds of the redemption (a) exceed $50,000, (b) are to be paid to a person
other than the record owner, (c) are to be sent to an address other than the
address on the Transfer Agent's records, or (d) are to be paid to a corporation,
partnership, trust or fiduciary, the signature(s) on the redemption request and
on the certificates, if any, or stock power must be guaranteed by an "eligible
guarantor institution", and in the case of a corporate shareholder, a corporate
resolution must accompany the request. An "eligible guarantor institution"
includes any bank, broker, dealer or credit union. The Transfer Agent reserves
the right to request additional information from, and make reasonable inquiries
of, any eligible guarantor institution. For clients of Prusec, a signature
guarantee may be obtained from the agency or office manager of most Prudential
Insurance and Financial Services offices.

   
     In order to allow for the management of the Series with maximum
flexibility, you are urged to initiate redemptions of shares as early in the day
as possible and to notify the Series by at least 9:30 A.M., New York time, of
withdrawals in excess of $10 million.

     The Series reserves the right to withhold wiring redemption proceeds to
shareholders if, in the judgment of the investment adviser, the Series could be
adversely affected by making immediate payment, and may take up to seven days to
wire redemption proceeds. In making withdrawal requests, you must supply your
name(s), account number and personal identification number. Neither the Series
nor PMFS will be responsible for further verification of the authenticity of
telephoned instructions.
    

     You may change the bank account you have designated to receive amounts
withdrawn at any time by writing to PMFS with an appropriate signature guarantee
or by providing a certified copy of a corporate resolution authorizing the
change. Further documentation may be required when deemed appropriate by PMFS.

   
     REDEMPTION IN KIND. If the Board of Directors determines that it would be
detrimental to the best interests of the remaining shareholders of the Series to
make payment wholly or partly in cash, the Series may pay the redemption price
in whole or in part by a distribution in kind of securities from the investment
portfolio of the Series, in lieu of cash, in conformity with applicable rules of
the SEC. Securities will be readily marketable and will be valued in the same
manner as in a regular redemption. See "How the Series Values its Shares." If
your shares are redeemed in kind, you would incur transaction costs in
converting the assets into cash. The Series, however, has elected to be governed
by Rule 18f-1 under the Investment Company Act, pursuant to which the Series is
obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of
the net asset value of the Series during any 90-day period for any one
shareholder.

     INVOLUNTARY REDEMPTION. The Series reserves the right to redeem, upon 60
days' written notice, an account which is reduced by you because of a redemption
to a net asset value of less than $100,000. You may avoid this redemption by
increasing the net asset value of your account to $100,000 or more.
    

     The total value of a shareholder's investment in the Series at the time of
redemption may be more or less than his or her cost, depending on the value of
the securities held by the Series at such time and income earned.

     Under the Investment Company Act, the right of redemption may be suspended
or date of payment postponed at times when the New York Stock Exchange is closed
(other than customary weekend or holiday closings), trading on the New York
Stock Exchange is restricted, and under certain emergency or other circumstances
as determined by the SEC.


                                       17

<PAGE>

In case of suspension of the right of redemption, requests for redemption may be
withdrawn or shareholders may receive payment based on the net asset value
determined next after the termination of the suspension.

   
     AUTOMATIC REDEMPTION. Redemptions will be automatically effected by
Prudential Securities to satisfy debit balances arising under the COMMAND
Program or the BusinessEdge Program, such as those incurred by use of the
Visa(R) Gold Debit Card Account (for COMMAND Program) or the BusinessEdge
Visa(R) Debit Card Account (for BusinessEdge Program), including ATM transaction
purchases, cash advances and COMMAND Program or BusinessEdge Program Account
checks. The COMMAND Program or BusinessEdge Program Securities Account (the
Securities Account) will be automatically scanned for debits each business day
as of the close of business on that day. After application of any free credit
cash balances in the account to such debits, a sufficient number of shares of
the mutual fund selected by the participant that he or she has designated as his
or her primary fund for the investment or free credit cash balances (the Primary
Fund) will be redeemed as of that business day to satisfy any remaining debits
in the Securities Account and, if necessary, shares of other COMMAND Program or
BusinessEdge Program Account Funds, as applicable, owned by the Program
participant which have not been selected as his or her Primary Fund or shares of
a participant's money market funds managed by PIFM which are not Primary Funds
will be redeemed to satisfy debits in the Securities Account. Margin loans, if
available and selected under a Program, will be utilized to satisfy debits
remaining after the liquidation of all fund shares in a Securities Account, and
shares may not be purchased until all debits, margin loans and other
requirements in the Securities Account are satisfied. In the event of an
automatic redemption of shares, the participant will be entitled to dividends
declared on the redeemed shares through the business day preceding the day on
which the redemption is effective. Participants will not be entitled to
dividends declared on the date of redemption.

     MANUAL REDEMPTION. A shareholder investing through the COMMAND Program or
the BusinessEdge Program may redeem shares of the Series by submitting a written
request for redemption directly to the Distributor or by calling his or her
Prudential Securities Financial Advisor or Pruco Securities broker, as
applicable, who will submit the request to the Series' Transfer Agent. The
proceeds from a manual redemption will immediately become free credit cash
balances in the participant's Program Securities Account and will be
automatically invested in the Primary Fund selected as the participant's Primary
Fund. Redemption requests should not be sent to the Transfer Agent. If
inadvertently sent to the Transfer Agent, they will be forwarded to Prudential
Securities. The COMMAND Program and the BusinessEdge Program require the written
request to be signed by all persons in whose names the shares are registered,
exactly as their names appear on the Program Account Client Statement. In
certain instances, additional documents such as, but not limited to, trust
instruments, death certificates, appointments as executor or administrator or
certificates of corporate authority may be required.

     Under the COMMAND Program, Prudential Securities has the right to terminate
a Program Securities Account for any reason. Likewise, Prudential Securities or
Pruco Securities has the right to terminate a BusinessEdge Program Securities
Account for any reason. In either such event, all shares held in a shareholder's
account will be redeemed.

FREQUENT TRADING

     The Fund and the other Prudential Mutual Funds are not intended to serve as
vehicles for frequent trading in response to short-term fluctuations in the
market. Due to the disruptive effect that market timing investment strategies
and excessive trading can have on efficient portfolio management, the Fund
reserves the right to refuse purchase orders and exchanges by any person, group
or commonly controlled accounts, if, in the Manager's sole judgment, such
person, group or accounts were following a market timing strategy or were
otherwise engaging in excessive trading (Market Timers).

     To implement this authority to protect the Fund and its shareholders from
excessive trading, the Fund will reject all exchanges and purchases from a
Market Timer unless the Market Timer has entered into a written agreement with
the Fund or its affiliates pursuant to which the Market Timer has agreed to
abide by certain procedures, which include a daily dollar limit on trading. The
Fund may notify the Market Timer of rejection of an exchange or purchase order
subsequent to the day on which the order was placed.

SHAREHOLDER SERVICES

     As a shareholder in the Series, you can take advantage of the following
additional services and privileges:

     o SHAREHOLDER INVESTMENT ACCOUNT. Upon the initial purchase of shares of
the Series, a Shareholder Investment Account is established for you under which
your shares are held by PMFS.

     PMFS maintains an account for you expressed in terms of full and fractional
shares of the Series rounded to the nearest 1/1000th of a share. All investments
in the Series are credited to your account in the form of shares immediately
upon acceptance and become entitled to dividends as described in "Taxes,
Dividends and Distributions." PMFS will also maintain subaccounts for investors.
See "Subaccounting and Special Services" below.

     Stock certificates are issued only upon your written request. PMFS will
provide a confirmation of all investments in or withdrawals from an account.
Within ten days after the end of each month, PMFS will send you a statement
setting forth a summary of the transactions in your account for the month and
the month-end balance of full and fractional shares held in the account.

     o SUBACCOUNTING AND SPECIAL SERVICES. Special processing can be arranged
with PMFS for corporations, banks and other institutions that wish to open
multiple accounts (a master account and subaccounts). An investor wishing to
avail itself of PMFS's subaccounting facilities or other special services for
individual or multiple accounts will be required to enter into a separate
agreement with PMFS. Charges for these services, if any, will be determined on
the basis of the level of services to be rendered. Subaccounts may be opened at
the time of the initial investment or at a later date.

     o EXCHANGE PRIVILEGE. The Fund does not currently offer an exchange
privilege for shares of the Series, except that Class A shareholders of the
Series who qualify to purchase Class I shares will have their Class A shares
exchanged for Class I shares on a quarterly basis.

     o REPORTS TO SHAREHOLDERS. The Fund will send you annual and semi-annual
reports. The financial statements appearing in the annual reports are audited by
independent accountants. In order to reduce duplicate mailing and printing
expenses, the Fund will provide one annual and semi-annual shareholder report
and annual prospectus per household. You may request additional copies of such
reports by calling (800) 225-1852 or by writing to the Fund at Gateway Center
Three, 100 Mulberry Street, Newark, New Jersey 07102-4077.

     o SHAREHOLDER INQUIRIES. Shareholder inquiries should be addressed to the
Fund at Gateway Center Three, 100 Mulberry Street, Newark, New Jersey
07102-4077, or by telephone, at (800) 521-7466 (toll-free).

                         DESCRIPTION OF SECURITY RATINGS

MOODY'S INVESTORS SERVICE
BOND RATINGS

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

     Aa: Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than Aaa bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.

SHORT-TERM DEBT RATINGS

     Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations which have an original maturity not
exceeding one year.

     Prime-1: Issuers rated Prime-1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations.

     Prime-2: Issuers rated Prime-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations.

SHORT-TERM RATINGS

     VMIG-1: Variable rate short-term indebtedness rated "VMIG-1" is of the best
quality. There is present strong protection by established cash flows, superior
liquidity support or demonstrated broad-based access to the market for
refinancing.

STANDARD & POOR'S RATINGS GROUP
BOND RATINGS

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

     AA: Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.

COMMERCIAL PAPER RATINGS

     An S&P commercial paper rating is a current assessment of the likelihood of
timely payment of debt considered short-term in the relevant market.

     A-1: This highest category indicates that the degree of safety regarding
timely payment is strong.

     A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated A-1.


                                      A-1

<PAGE>

DUFF & PHELPS CREDIT RATING CO.

LONG-TERM DEBT RATINGS

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

     AA: Bonds rated AA are considered to be of high credit quality. Protection
factors are strong. Risk is modest but may vary slightly from time to time
because of economic conditions.

SHORT-TERM DEBT RATINGS

     D-1+: Highest certainty of timely payment. Short-term liquidity, including
internal operating factors and/or access to alternative sources of funds, is
outstanding, and safety is just below risk-free U.S. Treasury short-term
obligations.

     D-1: Very high certainty of timely payment. Liquidity factors are excellent
and supported by good fundamental protection factors. Risk factors are minor.

     D-1-: High certainty of timely payment. Liquidity factors are strong and
supported by good fundamental protection factors. Risk factors are very small.

     D-2: Good certainty of timely payment. Liquidity factors and company
fundamentals are sound. Although ongoing funding needs may enlarge total
financing requirements, access to capital markets is good. Risk factors are
small.

FITCH INVESTORS SERVICES, L.P.

BOND RATINGS

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

     AA: Bonds considered to be investment grade and of very high credit
quality. The obligor's ability to pay interest and repay principal is very
strong, although not quite as strong as bonds rated 'AAA'. Because bonds rated
in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable
future developments, short-term debt of these issuers is generally rated 'F-1+'.

SHORT-TERM DEBT RATINGS

     F-1+: Exceptionally Strong Credit Quality. Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

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

     F-2: Good Credit Quality. Issues assigned this rating have a satisfactory
degree of assurance for timely payment, but the margin of safety is not as great
as the 'F-1+' and 'F-1' categories.

<PAGE>

                        INVESTMENT OBJECTIVE AND POLICIES

     The investment objective of each Series is high current income consistent
with the preservation of principal and liquidity.

OBLIGATIONS ISSUED OR GUARANTEED BY THE U.S. GOVERNMENT, ITS AGENCIES AND
INSTRUMENTALITIES AND THIRD PARTIES

     Each Series may invest in component parts of U.S. Treasury notes or bonds,
namely, either the corpus (principal) of such Treasury obligations or one of the
interest payments scheduled to be paid on such obligations. These obligations
may take the form of (i) Treasury obligations from which the interest coupons
have been stripped, (ii) the interest coupons that are stripped, (iii)
book-entries at a Federal Reserve member bank representing ownership of Treasury
obligation components, or (iv) receipts evidencing the component parts (corpus
or coupons) of Treasury obligations that have not actually been stripped. Such
receipts evidence ownership of component parts of Treasury obligations (corpus
or coupons) purchased by a third party (typically an investment banking firm)
and held on behalf of the third party in physical or book-entry form by a major
commercial bank or trust company pursuant to a custody agreement with the third
party. Treasury obligations, including those underlying such receipts, are
backed by the full faith and credit of the U.S. Government.

     Obligations issued or guaranteed as to principal and interest by the U.S.
Government may be acquired by a Series in the form of custodial receipts that
evidence ownership of future interest payments, principal payments or both on
certain United States Treasury notes or bonds. Such notes and bonds are held in
custody by a bank on behalf of the owners. These custodial receipts are known by
various names, including "Treasury Receipts," "Treasury Investment Growth
Receipts" (TIGRs) and "Certificates of Accrual on Treasury Securities" (CATS).
Neither Series intends to purchase TIGRs or CATS during the coming year.

LENDING OF SECURITIES

     Consistent with applicable regulatory requirements, a Series may lend its
portfolio securities to brokers, dealers and financial institutions, provided
that outstanding loans do not exceed in the aggregate 15% of the value of the
Series' total assets and provided that such loans are callable at any time by
the Series and are at all times secured by cash or equivalent collateral that is
equal to at least the market value, determined daily, of the loaned securities.
The advantage of such loans is that a Series continues to receive payments in
lieu of the interest on the loaned securities, while at the same time earning
interest either directly from the borrower or on the collateral which will be
invested in short-term obligations.

     A loan may be terminated by the borrower on one business day's notice or by
a Series at any time. If the borrower fails to maintain the requisite amount of
collateral, the loan automatically terminates, and the Series could use the
collateral to replace the securities while holding the borrower liable for any
excess of replacement cost over collateral. As with any extensions of credit,
there are risks of delay in recovery and in some cases loss of rights in the
collateral should the borrower of the securities fail financially. However,
these loans of portfolio securities will only be made to firms determined to be
creditworthy pursuant to procedures approved by the Board of Directors of the
Fund. On termination of the loan, the borrower is required to return the
securities to the Series, and any gain or loss in the market price during the
loan would inure to that Series.

     Each Series will pay reasonable finders', administrative and custodial fees
in connection with a loan of its securities or may share the interest earned on
collateral with the borrower.

     Neither Series intends to lend its securities during the coming year.

LIQUIDITY PUTS

   
     A Series may purchase instruments of the types described in the relevant
Prospectus under "How the Series Invests--Investment Objective and Policies"
together with the right to resell the instruments at an agreed-upon price or
yield within a specified period prior to the maturity date of the instruments.
Such a right to resell is commonly known as a "put," and the aggregate price
which the Series pays for instruments with puts may be higher than the price
which otherwise would be paid for the instruments. Consistent with the Series'
investment objective and applicable rules issued by the Securities and Exchange
Commission (SEC) and subject to the supervision of the Board of Directors, the
purpose of this practice is to permit a Series to be fully invested while
preserving the necessary liquidity to meet unusually large redemptions and to
purchase at a later date securities other than those subject to the put. A
Series may choose to exercise puts during periods in which proceeds from sales
of its shares and from recent sales of portfolio securities are insufficient to
meet redemption requests or when the funds available are otherwise allocated for
investment. In determining whether to exercise puts prior to their expiration
date and in selecting which puts to exercise in such circumstances, the
investment adviser considers, among other things, the amount of cash available
to a Series, the expiration dates of the available puts, any future commitments
for securities purchases, the yield, quality
    


                                      B-2

<PAGE>

and maturity dates of the underlying securities, alternative investment
opportunities and the desirability of retaining the underlying securities in
such Series' portfolio.

     Each Series values instruments which are subject to puts at amortized cost;
no value is assigned to the put. The cost of the put, if any, is carried as an
unrealized loss from the time of purchase until it is exercised or it expires.

     Each Series will invest no more than 5% of its total assets in securities
issued by or subject to puts from the same institution. For purposes of this
limitation, unconditional puts or guarantees with respect to a security will not
be deemed to be issued by the institution providing the guarantee or put if the
value of all securities held by a Series and issued or guaranteed by the issuer
providing the guarantee or put are limited to 10% of a Series' total assets.

FLOATING RATE AND VARIABLE RATE SECURITIES

   
     The Fund may purchase "floating rate" and "variable rate" securities.
Investments in floating or variable rate securities normally will involve
securities which provide that the rate is set as a spread to a designated base
rate, such as rates on Treasury bills, and, in some cases, that the purchaser
can demand payment of the obligation at specified intervals or after a specified
notice period (in each case a period of less than thirteen months) at par plus
accrued interest, which amount may be more or less than the amount paid for the
obligation. Variable rate securities provide for a specified periodic adjustment
in the interest rate, while floating rate securities have an interest rate which
changes whenever there is a change in the designated base interest rate.
    

ILLIQUID SECURITIES

     Neither Series may hold more than 10% of its net assets in illiquid
securities, including securities that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale and
repurchase agreements which have a maturity of longer than seven days.
Historically, illiquid securities have included securities subject to
contractual or legal restrictions on resale because they have not been
registered under the Securities Act of 1933, as amended (Securities Act),
securities which are otherwise not readily marketable and repurchase agreements
having a maturity of longer than seven days. Securities which have not been
registered under the Securities Act are referred to as private placements or
restricted securities and are purchased directly from the issuer or in the
secondary market. Mutual funds do not typically hold a significant amount of
these restricted or other illiquid securities because of the potential for
delays on resale and uncertainty in valuation. Limitations on resale may have an
adverse effect on the marketability of portfolio securities and a mutual fund
might be unable to dispose of restricted or other illiquid securities promptly
or at reasonable prices and might thereby experience difficulty satisfying
redemptions within seven days. A mutual fund might also have to register such
restricted securities in order to dispose of them, resulting in additional
expense and delay. Adverse market conditions could impede such a public offering
of securities.

     In recent years, however, a large institutional market has developed for
certain securities that are not registered under the Securities Act, including
repurchase agreements, commercial paper, foreign securities, municipal
securities and corporate bonds and notes. Institutional investors depend on an
efficient institutional market in which the unregistered security can be readily
resold or on an issuer's ability to honor a demand for repayment. The fact that
there are contractual or legal restrictions on resale to the general public or
to certain institutions may not be indicative of the liquidity of such
securities.

     Rule 144A of the Securities Act allows for a broader institutional trading
market for securities otherwise subject to restriction on resale to the general
public. Rule 144A establishes a "safe harbor" from the registration requirements
of the Securities Act for resales of certain securities to qualified
institutional buyers. The investment adviser anticipates that the market for
certain restricted securities such as institutional commercial paper and foreign
securities will expand further as a result of this regulation and the
development of automated systems for the trading, clearance and settlement of
unregistered securities of domestic and foreign issuers, such as the PORTAL
System sponsored by the National Association of Securities Dealers, Inc.

     Restricted securities eligible for resale pursuant to Rule 144A under the
Securities Act and commercial paper for which there is a readily available
market will not be deemed to be illiquid. The investment adviser will monitor
the liquidity of such restricted securities subject to the supervision of the
Board of Directors. In reaching liquidity decisions, the investment adviser will
consider, inter alia, the following factors: (1) the frequency of trades and
quotes for the security; (2) the number of dealers wishing to purchase or sell
the security and the number of other potential purchasers; (3) dealer
undertakings to make a market in the security; and (4) the nature of the
security and the nature of the marketplace trades (e.g., the time needed to
dispose of the security, the method of soliciting offers and the mechanics of
the transfer). In addition, in order for commercial paper that is issued in
reliance on Section 4(2) of the Securities Act to be considered liquid, (i) it
must be rated in one of the two highest rating categories by at least two
nationally recognized statistical rating organizations (NRSRO), or if only one
NRSRO rates the securities, by that NRSRO, or, if unrated, be of comparable
quality in the view of the investment adviser; and (ii) it must not be


                                      B-3

<PAGE>

"traded flat" (i.e., without accrued interest) or in default as to principal or
interest. Repurchase agreements subject to demand are deemed to have a maturity
equal to the notice period.

SECURITIES OF OTHER INVESTMENT COMPANIES

     A Series may invest up to 10% of its net assets in securities of other
money market funds registered under the Investment Company Act. Generally, each
Series does not intend to invest more than 5% of its net assets in such
securities. To the extent that a Series invests in securities of other
registered investment companies, shareholders of the Series may be subject to
duplicate management and advisory fees.

REPURCHASE AGREEMENTS

     The Liquid Assets Series participates in a joint repurchase account with
other investment companies managed by Prudential Investments Fund Management LLC
(PIFM or the Manager) pursuant to an order of the Securities and Exchange
Commission. On a daily basis, any uninvested cash balances of the Series may be
aggregated with those of such other investment companies and invested in one or
more repurchase agreements. Each fund participates in the income earned or
accrued in the joint account based on the percentage of its investment. In
connection with transactions in repurchase agreements with U.S. financial
institutions, it is the Fund's policy that its custodian or designated
subcustodians, as the case may be, under triparty repurchase agreements, take
possession of the underlying collateral securities, the value of which equals or
exceeds the resale price of the agreement. If the seller defaults and the value
of the collateral declines or if bankruptcy proceedings are commenced with
respect to the seller of the security, realization of the collateral by the Fund
may be delayed or limited.

     The IMM Series does not currently participate in the joint repurchase
account.

                             INVESTMENT RESTRICTIONS

     The following restrictions are fundamental policies. Fundamental policies
are those which cannot be changed without the approval of the holders of a
majority of the outstanding voting securities of a Series. A "majority of the
outstanding voting securities," when used in this Statement of Additional
Information, means the lesser of (i) 67% of the voting shares represented at a
meeting at which more than 50% of the outstanding voting shares are present in
person or represented by proxy or (ii) more than 50% of the outstanding voting
shares.

     A Series may not:

     1. Purchase securities on margin (but a Series may obtain such short-term
credits as may be necessary for the clearance of transactions); provided that
the deposit or payment by a Series of initial or maintenance margin in
connection with options or futures contracts is not considered the purchase of a
security on margin.

     2. Make short sales of securities or maintain a short position.

     3. Issue senior securities, borrow money (including through the entry into
reverse repurchase agreement transactions) or pledge its assets, except that a
Series may borrow up to 15% of the value of its total assets (calculated when
the loan is made) from banks for temporary, extraordinary or emergency purposes
and may pledge up to 15% of the value of its total assets to secure such
borrowings. No Series will purchase portfolio securities if its borrowings
exceed 5% of its net assets. The purchase or sale of securities on a
"when-issued" or delayed delivery basis, the entry into reverse repurchase
agreements and the purchase and sale of financial futures contracts and
collateral arrangements with respect thereto are not deemed to be a pledge of
assets and such arrangements are not deemed to be the issuance of a senior
security.

     4. Purchase any security (other than obligations of the U.S. Government,
its agencies or instrumentalities) if as a result, with respect to 75% of the
value of the Series' total assets, more than 5% of the value of the Series'
total assets would be invested in the securities of a single issuer.

     5. Purchase any securities (other than obligations of the U.S. Government,
its agencies and instrumentalities) if, as a result, 25% or more of the value of
a Series' total assets (determined at the time of investment) would be invested
in the securities of one or more issuers conducting their principal business
activities in the same industry, provided that there is no limitation with
respect to money market instruments of domestic banks. For purposes of this
exception, domestic banks shall include all banks which are organized under the
laws of United States or a state (as defined in the Investment Company Act),
U.S. branches of foreign banks that are subject to the same regulations as U.S.
banks and foreign branches of domestic banks.

     6. Buy or sell real estate or interests in real estate, except that a
Series may purchase and sell securities which are secured by real estate,
securities of companies which invest or deal in real estate and publicly traded
securities of real estate investment trusts. A Series may not purchase interests
in real estate limited partnerships which are not readily marketable.


                                      B-4

<PAGE>

     7. Act as underwriter except to the extent that, in connection with the
disposition of portfolio securities, it may be deemed to be an underwriter under
certain federal securities laws.

     8. Make investments for the purpose of exercising control or management.

     9. Invest in securities of other registered investment companies, except by
purchases in the open market involving only customary brokerage commissions and
as a result of which not more than 10% of its total assets (determined at the
time of investment) would be invested in such securities, or except as part of a
merger, consolidation or other acquisition.

     10. Invest in interests in oil, gas or other mineral exploration or
development programs, except that the Series may invest in the securities of
companies which invest in or sponsor such programs.

     11. Make loans, except through (i) repurchase agreements and (ii) loans of
portfolio securities (limited to 15% of the value of a Series' total assets).

     12. Purchase common stock or other voting securities, preferred stock,
warrants or other equity securities, except as may be permitted by restriction
number 9.

     13. Enter into reverse repurchase agreements if, as a result thereof, a
Series' obligations with respect to reverse repurchase agreements would exceed
15% of the value of the Series' total assets.

     14. Buy or sell commodities or commodity contracts, except that a Series
may purchase and sell futures contracts and options thereon.

   
     Whenever any fundamental investment policy or investment restriction states
a maximum percentage of a Series' assets, it is intended that if the percentage
limitation is met at the time the investment is made, a later change in
percentage resulting from changing total or net asset values will not be
considered a violation of such policy. However, in the event that a Series'
asset coverage for borrowings falls below 300%, such Series will take prompt
action to reduce its borrowings, as required under the Investment Company Act.

     Prudential Investments Fund Management LLC, Gateway Center Three, 100
     Mulberry Street, Newark, New Jersey 07102-4077.

*    "Interested" Director of the Fund, as defined in the Investment Company Act
     of 1940 (the Investment Company Act).

   
     Directors and officers of the Fund are also trustees, directors and
officers of some or all of the other investment companies distributed by
Prudential Securities or Prudential Investment Management Services LLC.

     The officers conduct and supervise the daily business operations of the
Fund, while the Directors, in addition to their functions set forth under
"Manager" and "Distributor," review such actions and decide on general policy.

     The Directors have adopted a retirement policy which calls for the
retirement of Directors on December 31 of the year in which they reach the age
of 72, except that retirement is being phased in for Directors who were age 68
or older as of December 31, 1993. Under this phase-in provision, Messrs. Beach
and Eyre are scheduled to retire on December 31, 1999 and December 31, 1998,
respectively.

     The Fund pays each of its Directors who is not an affiliated person of PIFM
or Prudential Investments (PI) annual compensation of $1,500, in addition to
certain out-of-pocket expenses. The amount of annual compensation paid to each
Director may change as a result of the introduction of additional funds upon
which the Director will be asked to serve.

     Directors may receive their Director's fees pursuant to a deferred fee
agreement with the Fund. Under the terms of the agreement, the Fund accrues
daily the amount of such Director's fees in installments which accrue interest
at a rate equivalent to the prevailing rate applicable to 90-day U.S. Treasury
Bills at the beginning of each calendar quarter or, pursuant to an SEC exemptive
order, at the daily rate of return of the Fund (the Fund rate). The minimum
initial investment requirement is waived for Directors who receive their fees
pursuant to a deferred fee agreement. Payment of the interest so accrued is also
deferred and accruals become payable at the option of the Director. The Fund's
obligation to make payments of deferred Directors' fees, together with interest
thereon, is a general obligation of the Fund.

     Pursuant to the terms of the Management Agreement with the Fund, the
Manager pays all compensation of officers of the Fund as well as the fees and
expenses of all Directors of the Fund who are affiliated persons of the Manager.

   
     The following table sets forth the aggregate compensation paid by the Fund
to the Directors who are not affiliated with the Manager for the fiscal year
ended March 31, 1998 and the aggregate compensation paid to such Directors for
service on the Fund's Board and that of all other funds managed by Prudential
Investments Fund Management LLC (Fund Complex) for the calendar year ended
December 31, 1997.

                                     MANAGER

   
     The manager of the Fund is Prudential Investments Fund Management LLC (PIFM
or the Manager), formerly, Prudential Mutual Fund Management LLC, Gateway Center
Three, 100 Mulberry Street, Newark, New Jersey 07102-4077. PIFM serves as
manager to all of the other investment companies that, together with the Series,
comprise the Prudential Mutual Funds. See "How the Series is Managed" in the
relevant Prospectus. As of April 30, 1998, PIFM managed and/or administered
open-end and closed-end management investment companies with assets of
approximately $64.8 billion. According to the Investment Company Institute, as
of December 31, 1997, the Prudential Mutual Funds were the 17th largest family
of mutual funds in the United States.
    

   
     PIFM is a subsidiary of Prudential Securities. Prudential Mutual Fund
Services LLC (PMFS or the Transfer Agent), a wholly-owned subsidiary of PIFM,
serves as the transfer agent for the Prudential Mutual Funds and, in addition,
provides customer service, recordkeeping and management and administration
services to qualified plans.

     Pursuant to the Management Agreement for the IMM Series (the Management
Agreement) and the Management and Administrative Services Agreement
(Administrative Services Agreement) for the LA Series, PIFM, subject to the
supervision of the Fund's Board of Directors and in conformity with the stated
policies of each Series, manages both the investment operations of each Series
and the composition of the Series' portfolio, including the purchase, retention,
disposition and loan of securities. In connection therewith, PIFM is obligated
to keep certain books and records of the Series. PIFM also administers the
Series' corporate affairs and, in connection therewith, furnishes the Series
with office facilities, together with those ordinary clerical and bookkeeping
services which are not being furnished by State Street Bank and Trust Company,
the Series' custodian, and PMFS, each Series' transfer and shareholder servicing
agent. The management services of PIFM for the Series are not exclusive under
the terms of the Management Agreement and PIFM is free to, and does, render
management services to others.

     For its services, PIFM receives, pursuant to the Management Agreement with
the Fund, a fee at an annual rate of .20 of 1% of the average daily net assets
of the IMM Series. The fee is computed daily and payable monthly. The Management
Agreement provides that, in the event the expenses of the Fund for any fiscal
year (including the fees payable to PIFM, but excluding interest, taxes,
brokerage commissions, distribution fees and litigation and indemnification
expenses and other extraordinary expenses not incurred in the ordinary course of
the Fund's business) exceed the lowest applicable annual expense limitation
established and enforced pursuant to the statute or regulations of any
jurisdiction in which shares of the Fund are then qualified for offer and sale,
the compensation due to PIFM will be reduced by the amount of such excess, or,
if such reduction exceeds the compensation payable to PIFM, PIFM will pay to the
Fund the amount of such reduction which exceeds the amount of such compensation.
Any such reductions or payments are subject to readjustment during the year. No
such reductions were required during the fiscal year ended March 31, 1998. No
jurisdiction currently limits the Fund's expenses.
    

     For its services, PIFM receives its reasonable costs and expenses from the
LA Series pursuant to the Administrative Services Agreement. 

   
     In connection with its management of the corporate affairs of each Series,
PIFM bears the following expenses:

          (a) the salaries and expenses of all of its and each Series'
     personnel, except the fees and expenses of Directors who are not affiliated
     persons of PIFM or the Series' investment adviser;

          (b) all expenses incurred by PIFM or by a Series in connection with
     managing the ordinary course of such Series' business, other than those
     assumed by a Series, as described below; and
    

          (c) the costs and expenses payable to The Prudential Investment
     Corporation, doing business as Prudential Investments (PI or the
     Subadvisor), pursuant to a subadvisory agreement between PIFM and PI (the
     Subadvisory Agreement).


                                      B-9

<PAGE>

   
     Under the terms of the Management Agreement and the Administrative Services
Agreement, each Series is responsible for the payment of the following expenses,
including (a) the fees payable to the Manager, (b) the fees and expenses of
Directors who are not affiliated with the Manager or such Series' investment
adviser, (c) the fees and certain expenses of each Series' Custodian and
Transfer and Dividend Disbursing Agent, including the cost of providing records
to the Manager in connection with its obligation to maintain required records of
each Series and of pricing such Series' shares, (d) the charges and expenses of
legal counsel and independent accountants of each Series, (e) brokerage
commissions and any issue or transfer taxes chargeable to such Series in
connection with its securities and futures transactions, (f) all taxes and
corporate fees payable by such Series to governmental agencies, (g) the fees of
any trade association of which such Series is a member, (h) the cost of stock
certificates representing and/or non-negotiable share deposit receipts
evidencing shares of such Series, (i) the cost of fidelity and liability
insurance, (j) the fees and expenses involved in registering and maintaining
registration of such Series and of its shares with the SEC and the states,
including the preparation and printing of the Fund's registration statements and
prospectuses for such purposes, (k) allocable communications expenses with
respect to investor services and all expenses of shareholders' and Directors'
meetings and of preparing, printing and mailing reports, proxy statements and
prospectuses to shareholders, (l) litigation and indemnification expenses and
other extraordinary expenses not incurred in the ordinary course of such Series'
business and (m) distribution fees.

     The Management Agreement and the Administration Services Agreement also
provide that PIFM will not be liable for any error of judgment or any loss
suffered by the relevant Series in connection with the matters to which the
Management Agreement and the Administration Services Agreement relate, except a
loss resulting from willful misfeasance, bad faith, gross negligence or reckless
disregard of duty. The Management Agreement and the Administration Services
Agreement each provide that each will terminate automatically if assigned (as
defined in the Investment Company Act), and that each may be terminated without
penalty by either party upon not more than 60 days' nor less than 30 days'
written notice. The Management Agreement and the Administration Services
Agreement provide that each said agreement will continue in effect for a period
of more than two years from its execution only so long as such continuance is
specifically approved at least annually in accordance with the requirements of
the Investment Company Act.

     For the fiscal years ended March 31, 1998, 1997 and 1996, the IMM Series
paid management fees to PIFM of $1,259,305, $898,786, and $1,039,892,
respectively.

     PIFM has entered into a Subadvisory Agreement with PI (the Subadviser), a
wholly-owned subsidiary of Prudential. The Subadvisory Agreement provides that
PI furnish investment advisory services in connection with the management of
each Series. In connection therewith, PI is obligated to keep certain books and
records of the Series. PIFM continues to have responsibility for all investment
advisory services pursuant to the Management Agreement and supervises PI's
performance of such services. PI is reimbursed by PIFM for the reasonable costs
and expenses incurred by PI in furnishing services to PIFM.

     The Subadviser maintains a corporate credit unit which provides credit
analysis and research on taxable fixed-income securities including money market
instruments. The portfolio manager consults routinely with the credit unit in
managing the Series' portfolios. The credit unit, with a staff including 7
credit analysts, reviews on an ongoing basis commercial paper issuers,
commercial banks, non-bank financial institutions and issuers of other taxable
fixed-income obligations. Credit analysts have broad access to research and
financial reports, data retrieval services and industry analysts. They maintain
relationships with the management of corporate issuers and from time to time
visit companies in whose securities the Series may invest.
    

     The Subadvisory Agreement provides that it will terminate in the event of
its assignment (as defined in the Investment Company Act) or, in the case of IMM
Series, upon the termination of the Management Agreement and, in the case of LA
Series, upon the termination of the Administration Services Agreement. The
Subadvisory Agreement may be terminated by the Fund, PIFM or PI upon not more
than 60 days' nor less than 30 days' written notice. The Subadvisory Agreement
provides that it will continue in effect for a period of more than two years
from its execution only so long as such continuance is specifically approved at
least annually in accordance with the requirements of the Investment Company
Act.

                                   DISTRIBUTOR

   
     Until July 1, 1998, Prudential Securities Incorporated (Prudential
Securities or, until July 1, 1998, the Distributor), One Seaport Plaza, New
York, New York 10292, will continue to act as the distributor of the shares of
each Series. Beginning July 1, 1998, Prudential Investment Management Services
LLC (the Distributor), Gateway Center Three, 100 Mulberry Street, Newark, New
Jersey 07102-4077, will act as Distributor of the Series' shares.
    

     Prudential Securities is engaged in the securities underwriting and
securities and commodities brokerage business and is a member of the New York
Stock Exchange, other major securities and commodities exchanges and the
National Association of


                                      B-10

<PAGE>

   
Securities Dealers, Inc. (NASD). Prudential Securities is also engaged in the
investment advisory business. Prudential Securities is a wholly-owned subsidiary
of Prudential Securities Group, Inc., which is an indirect, wholly-owned
subsidiary of Prudential. The services it provides to the Series are discussed
in the relevant Prospectus. See "How the Series is Managed--Distributor."
    

DISTRIBUTION AND SERVICE PLAN

   
     Under the Distribution and Service Plan (the Plan) and the Distribution
Agreement, the IMM Series reimburses the Distributor its distribution-related
expenses up to 0.12% of the average daily net assets of the Class A shares of
the Series, computed daily and payable monthly. There is no plan of distribution
for the LA Series. The Distributor incurs the expenses of distributing the IMM
Series Class I shares and the shares of the LA Series under the Distribution
Agreement, none of which are reimbursed by or paid for by the Fund. See "How the
Series is Managed--Distributor" in the relevant Prospectus.

     For the fiscal year ended March 31, 1998, PSI incurred distribution
expenses in the aggregate of approximately $168,500 with respect to the IMM
Series, under the Plan, all of which was recovered through the distribution fee
paid by the IMM Series. It is estimated that of this amount approximately 75%
($126,375) was spent on payment of account servicing fees to financial advisers
and 25% ($42,125) on allocation of overhead and other office
distribution-related expenses with respect to the IMM Series. The term "overhead
and other office distribution-related expenses" represents (a) the expenses of
operating Prudential Securities' branch offices in connection with the sale of
Class A shares of the Series, including lease costs, the salaries and employee
benefits of operations and sales support personnel, utility costs,
communications costs and the costs of stationery and supplies, (b) the costs of
client sales seminars, and (c) travel expenses of mutual fund sales coordinators
to promote the sale of Class A shares of the IMM Series.
    

     There are no carryover amounts under the Plan, and therefore interest and
carrying charges are not incurred under the Plan. So long as the Plan is in
effect, the selection and nomination of Directors who are not interested persons
of the Fund shall be committed to the discretion of the Directors who are not
interested persons. The Board of Directors has determined that, in its judgment,
there is a reasonable likelihood that the Plan will benefit the Series and its
shareholders.

     Pursuant to the Plan, the Directors will be provided with, and will review,
at least quarterly, a written report of the distribution expenses incurred on
behalf of the IMM Series by the Distributor. The report will include an
itemization of the distribution expenses and the purpose of such expenditures.

   
     The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval of the Class A shareholders
of the IMM Series, and all material amendments of the Plan must also be approved
by the Directors. The Plan may be terminated with respect to the IMM Series at
any time, by vote of a majority of the Directors who are not interested persons
of the Fund and who have no direct or indirect financial interest in the
operation of the Plan or any agreements related to the Plan (the Rule 12b-1
Directors) or by a vote of a majority of the outstanding voting securities of
the Class A shares of the Series (as defined in the Investment Company Act). The
Distribution Agreement provides that it will terminate automatically if assigned
and that it may be terminated, without payment of any penalty, by a majority of
the Rule 12b-1 Directors or by vote of a majority of the outstanding voting
securities of the Fund, or by the Distributor, on 60 days' written notice to the
other party.
    

     Pursuant to the Distribution Agreement, the Fund has agreed to indemnify
the Distributor to the extent permitted by applicable law against certain
liabilities under the federal securities laws.

     NASD MAXIMUM SALES CHARGE RULE. Pursuant to rules of the NASD, the
Distributor is required to limit aggregate initial sales charges, deferred sales
charges and asset-based sales charges to 6.25% of total gross sales of each
class of shares. Interest charges on unreimbursed distribution expenses equal to
the prime rate plus one percent per annum may be added to the 6.25% limitation.
Sales from the reinvestment of dividends and distributions are not included in
the calculation of the 6.25% limitation. The annual asset-based sales charge on
shares of the Fund may not exceed .75 of 1% per class. The 6.25% limitation
applies to each class of the Fund rather than on a per shareholder basis. If
aggregate sales charges were to exceed 6.25% of the total gross sales of any
class, all sales charges on shares of that class would be suspended.

                               PURCHASE OF SHARES

MULTIPLE ACCOUNTS

   
     An institution may open a single master account by filing an Application
with PMFS, signed by personnel authorized to act for the institution. Individual
subaccounts may be opened at the time the master account is opened by listing
them, or they may be added at a later date by written advice. Procedures will be
available to identify subaccounts by name and number within the master account
name. The foregoing procedures would also apply to related institutional
accounts (i.e., accounts of shareholders with a common institutional or
corporate parent). The investment minimums as set forth in the relevant
Prospectus under "Shareholder Guide--How to Buy Shares of the Series" are
applicable to the aggregate amounts invested by a group, and not to the amount
credited to each subaccount.
    

     PMFS provides each institution with a written confirmation for each
transaction in a subaccount. Further, PMFS is able to provide, to each
institution on a daily or monthly basis, a statement which sets forth for each
master account its share balance and income earned for the month. In addition,
each institution receives a statement for each individual account setting forth
transactions in the sub-account for the year-to-date, the total number of shares
owned as of the dividend payment date and the dividends paid for the current
month, as well as for the year-to-date.

REOPENING AN ACCOUNT

     Subject to the minimum investment requirements, an investor may reopen an
account, without filing a new application form, at any time during the calendar
year the account is closed, provided that the information on the old form is
still applicable.

LIQUID ASSETS SERIES

     Shares of the LA Series are not offered at the current time.

   
     ISSUANCE OF SERIES SHARES OF SECURITIES. Transactions involving the
issuance of Series shares for securities (rather than cash) will be limited to
(i) reorganizations, (ii) statutory mergers, or (iii) other acquisitions of
portfolio securities that: (a) meet the investment objective and policies of the
Series, (b) are liquid and not subject to restrictions on resale, (c) have a
value that is readily ascertainable via listing on or trading in a recognized
United States or international exchange or market, and (d) are approved by the
Series' investment adviser.
    

                                 NET ASSET VALUE

     Each Series uses the amortized cost method of valuation to determine the
value of its portfolio securities. In that regard, the Fund's Board of Directors
has determined to maintain a dollar-weighted average portfolio maturity of 90
days or less, to purchase only instruments having remaining maturities of
thirteen months or less, and to invest only in securities determined by the
investment adviser under the supervision of the Board of Directors to be of
minimal credit risk and to be of "eligible quality" in accordance with
regulations of the SEC. The remaining maturity of an instrument held by a Series
that is subject to a put is deemed to be the period remaining until the
principal amount can be recovered through demand or, in the case of a variable
rate instrument, the next interest reset date, if longer. The value assigned to
the put is zero. The Board of Directors also has established procedures designed
to stabilize, to the extent reasonably possible, a Series' price per share as
computed for the purpose of sales and redemptions at $1.00. Such procedures will
include review of a Series' portfolio holdings by the Board, at such intervals
as deemed appropriate, to determine whether a Series' net asset value calculated
by using available market quotations deviates from $1.00 per share based on
amortized cost. The extent of any deviation will be examined by the Board, and
if such deviation exceeds 1/2 of 1%, the Board will promptly consider what
action, if any, will be initiated. In the event the Board of Directors
determines that a deviation exists which may result in material dilution or
other unfair results to investors or existing shareholders, the Board will take
such corrective action as it regards necessary and appropriate, including the
sale of portfolio instruments prior to maturity to realize gains or losses, the
shortening of average portfolio maturity, the withholding of dividends or the
establishment of net asset value per share by using available market quotations.

   
     Each Series computes its net asset value at 4:00 P.M., New York time, on
each day a Series is open for business. In the event the New York Stock Exchange
closes early on any business day, the net asset value of the Series shares shall
be determined at the time between such closing and 4:00 P.M. New York time. The
New York Stock Exchange is closed on the following holidays: New Year's Day,
Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

   
     The Manager is responsible for decisions to buy and sell securities for
each Series, the selection of brokers and dealers to effect the transactions and
the negotiation of brokerage commissions, if any. (For purposes of this section,
the term "Manager" includes the Subadviser.) Neither Series normally incurs any
brokerage commission expense on such transactions. In the market for money
market instruments, securities are generally traded on a "net" basis, with
dealers acting as principal for their own accounts without a stated commission,
although the price of the security usually includes a profit to the dealer. In
underwritten offerings, securities are purchased at a fixed price which includes
an amount of compensation to the underwriter, generally referred to as the
underwriter's concession or discount. On occasion, certain money market
instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid. Portfolio securities may not be purchased
from any underwriting or selling syndicate of which Prudential Securities, or an
affiliate, during the existence of the syndicate, is a principal underwriter (as
defined in the Investment Company Act), except in accordance with rules of the
SEC. The Series will not deal with Prudential Securities or its affiliates on a
principal basis.

     In placing orders for portfolio securities of a Series, the Manager is
required to give primary consideration to obtaining the most favorable price and
efficient execution. This means that the Manager will seek to execute each
transaction at a price and commission, if any, which provide the most favorable
total cost or proceeds reasonably attainable under the circumstances. While the
Manager generally seeks reasonably competitive spreads or commissions, a Series
will not necessarily be paying the lowest spread or commission available. Within
the framework of this policy, the Manager may consider research and investment
services provided by brokers or dealers who effect or are parties to portfolio
transactions of the Series, the Manager or the Manager's other clients. Such
research and investment services are those which brokerage houses customarily
provide to institutional investors and include statistical and economic data and
research reports on particular companies and industries. Such services are used
by the Manager in connection with all of its investment activities, and some of
such services obtained in connection with the execution of transactions for a
Series may be used in managing other investment accounts. Conversely, brokers
furnishing such services may be selected for the execution of transactions for
such other accounts, whose aggregate assets are far larger than the Series', and
the services furnished by such brokers may be used by the Manager in providing
investment management for the Series. While such services are useful and
important in supplementing its own research and facilities, the Manager believes
that the value of such services is not determinable and does not significantly
reduce expenses. Neither Series reduces the advisory fee it pays to the Manager
by any amount that may be attributed to the value of such services.

     Subject to the above considerations, Prudential Securities may act as a
securities broker (or futures commission merchant) for the Series. In order for
Prudential Securities to effect any portfolio transactions for a Series, the
commissions, fees or other remuneration received by Prudential Securities must
be reasonable and fair compared to the commissions, fees or other remuneration
paid to other brokers in connection with comparable transactions involving
similar securities being purchased or sold during a comparable period of time.
This standard would allow Prudential Securities to receive no more than the
remuneration which would be expected to be received by an unaffiliated broker in
a commensurate arm's-length transaction. Furthermore, the Board of Directors of
the Fund, including a majority of the Directors who are not "interested"
persons, has adopted procedures which are reasonably designed to provide that
any commissions, fees or other remuneration paid to Prudential Securities are
consistent with the foregoing standard. Brokerage transactions with Prudential
Securities are also subject to such fiduciary standards as may be imposed by
applicable law.

     During the fiscal years ended March 31, 1996, 1997 and 1998, the Series
paid no brokerage commissions.

                       TAXES, DIVIDENDS AND DISTRIBUTIONS
    

     The IMM Series has elected to qualify and intends to remain qualified and
the LA Series intends to elect to qualify as a regulated investment company
under Subchapter M of the Internal Revenue Code of 1986, as amended. This
relieves a Series (but not its shareholders) from paying federal income tax on
income which is distributed to shareholders, and, if a Series did not realize
long-term capital gains permits net capital gains of the Series (i.e., the
excess of net long-term capital gains over net short-term capital losses) to be
treated as long-term capital gains of the shareholders, regardless of how long
shareholders have held their shares in that Series.

   
     Qualification as a regulated investment company requires, among other
things, that (a) at least 90% of the Series' annual gross income (without
reduction for losses from the sale or other disposition of securities or foreign
currencies) be derived from interest, dividends, payments with respect to
securities loans, and gains from the sale or other disposition of securities or
options thereon or foreign currencies, or other income (including, but not
limited to, gains from options, futures or forward contracts) derived with
respect to its business of investing in such securities or currencies; (b) a
Series diversify its holdings so that, at the
    


                                      B-13

<PAGE>

   
end of each quarter of the taxable year, (i) at least 50% of the market value of
a Series' assets is represented by cash, U.S. Government obligations and other
securities limited in respect of any one issuer to an amount not greater than 5%
of the market value of the Series' assets and 10% of the outstanding voting
securities of such issuer, and (ii) not more than 25% of the value of its assets
is invested in the securities of any one issuer (other than U.S. Government
obligations) and (c) the Series distribute to its shareholders at least 90% of
its net investment income and net short-term gains (i.e., the excess of net
short-term capital gains over net long-term capital losses) in each year.
    

     Gains or losses on sales of securities by a Series will be treated as
long-term capital gains or losses if the securities have been held by it for
more than one year. The Series do not anticipate realizing long-term capital
gains. Other gains or losses on the sale of securities will be short-term
capital gains or losses. In addition, debt securities acquired by a Series may
be subject to original issue discount and market discount rules.

     Each Series is required to distribute 98% of its ordinary income in the
same calendar year in which it is earned. Each Series is also required to
distribute during the calendar year 98% of the capital gain net income it earned
during the twelve months ending on October 31 of such calendar year, as well as
all undistributed ordinary income and undistributed capital gain net income from
the prior year or the twelve-month period ending on October 31 of such prior
year, respectively. To the extent it does not meet these distribution
requirements, a Series will be subject to a non-deductible 4% excise tax on the
undistributed amount. For purposes of this excise tax, income on which a Series
pays income tax is treated as distributed.

     It is anticipated that the net asset value per share of each Series will
remain constant. However, if the net asset value per share fluctuates and a loss
is realized on a sale, redemption or exchange of shares of a Series by a
shareholder, certain rules may apply which would limit the ability of the
shareholder to recognize such loss if, for example, the shareholder replaced the
shares within 30 days of the disposition of the shares.

     Dividends and distributions may also be subject to state and local taxes.

                              CALCULATION OF YIELD

     Each Series will prepare a current quotation of yield daily. The yield
quoted will be the simple annualized yield for an identified seven calendar day
period. The yield calculation will be based on a hypothetical account having a
balance of exactly one share at the beginning of the seven-day period. The base
period return will be the change in the value of the hypothetical account during
the seven-day period, including dividends declared on any shares purchased with
dividends on the shares, but excluding any capital changes, divided by the value
of the account at the beginning of the base period. The yield will vary as
interest rates and other conditions affecting money market instruments change.
Yield also depends on the quality, length of maturity and type of instruments in
a Series' portfolio, and its operating expenses. Each Series also may prepare an
effective annual yield computed by compounding the unannualized seven-day period
return as follows: by adding 1 to the unannualized seven-day period return,
raising the sum to a power equal to 365 divided by 7, and subtracting 1 from the
result.

     Effective yield = [(base period return+1)365/7]-1

     Comparative performance information may be used from time to time in
advertising or marketing the Series' shares, including data from Lipper
Analytical Services, Inc., Morningstar Publications, Inc., IBC Financial Data,
Inc., The Bank Rate Monitor, other industry publications, business periodicals
and market indices.

     Each Series' yield fluctuates, and an annualized yield quotation is not a
representation by the Series as to what an investment in the Series will
actually yield for any given period. Actual yields will depend upon not only
changes in interest rates generally during the period in which the investment in
a Series is held, but also on changes in the Series' expenses. Yield does not
take into account any federal or state income taxes.

               CUSTODIAN, TRANSFER AND SHAREHOLDER SERVICING AGENT
                           AND INDEPENDENT ACCOUNTANTS

   
     State Street Bank and Trust Company, One Heritage Drive, North Quincy,
Massachusetts 02171, serves as Custodian for each Series' portfolio securities,
and in that capacity maintains cash and certain financial and accounting books
and records pursuant to an agreement with the Fund.

     Prudential Mutual Fund Services LLC (PMFS), Raritan Plaza One, Edison, New
Jersey 08837, serves as the Transfer and Shareholder Servicing Agent of each
Series. It is a wholly-owned subsidiary of PIFM. PMFS provides customary
transfer agency services to each Series, including the handling of shareholder
communications, the processing of shareholder transactions, the maintenance of
shareholder account records, payment of dividends and distributions and related
functions. For these services, PMFS receives a monthly fee plus its
out-of-pocket expenses, including but not limited to postage, stationery,
printing, allocable communications and other costs. For the fiscal year ended
March 31, 1998, the IMM Series incurred fees of $240,000 for the services of
PMFS.

     Price Waterhouse LLP, 1177 Avenue of the Americas, New York, New York,
serves as the Series' independent accountants and in that capacity audits each
Series' annual financial statements.
    

                               GENERAL INFORMATION

     The Fund was incorporated on September 1, 1987 and originally consisted of
four series: the Institutional Money Market Series, the Institutional Government
Series, the Institutional Domestic Liquid Assets Series and the Institutional
Tax-Exempt Series. On or about June 30, 1989, sales of shares of the
Institutional Domestic Liquid Assets Series and the Institutional Tax-Exempt
Series were discontinued. Effective October 12, 1989, no shares remained
outstanding in those Series. On or about April 24, 1992, sales of shares of the
Institutional Government Series were discontinued. Effective May 15, 1992, no
shares remained outstanding in the Institutional Government Series. On August
28, 1995, the Board of Directors authorized the creation of the Liquid Assets
Series, although shares of such Series are not offered at this time.

Notes to Financial Statements             INSTITUTIONAL MONEY MARKET SERIES
- --------------------------------------------------------------------------------
Prudential Institutional Liquidity Portfolio, Inc. (the 'Fund') is registered
under the Investment Company Act of 1940 as an open-end, diversified management
investment company. The Fund consists of two series--the Institutional Money
Market Series (the 'Series') and the Liquid Assets Series. The Liquid Assets
Series has not yet begun operations. The investment objective of the Series is
high current income consistent with the preservation of principal and liquidity.
The Series invests primarily in money market instruments maturing in thirteen
months or less whose ratings are within the two highest ratings categories by a
nationally recognized statistical rating organization or, if not rated, are of
comparable quality. The ability of the issuers of the securities held by the
Series to meet their obligations may be affected by economic developments in a
specific industry or region.
- ------------------------------------------------------------
Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund, and the Series, in the preparation of its financial statements.
Securities Valuations: Portfolio securities are valued at amortized cost, which
approximates market value. The amortized cost method involves valuing a security
at its cost on the date of purchase and thereafter assuming a constant
amortization to maturity of any discount or premium.
Securities Transactions and Net Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses on sales of investments
are calculated on the identified cost basis. Interest income is recorded on the
accrual basis. Expenses are recorded on the accrual basis which may require the
use of certain estimates by management.
Net investment income (other than distribution fees) and unrealized and realized
gains or losses are allocated daily to each class of shares based upon the
relative proportion of net assets of each class at the beginning of the day.
Federal Income Taxes: It is the intent of the Fund to continue to meet the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable net income to its shareholders.
Therefore, no federal income tax provision is required.
Dividends and Distributions: The Fund declares all of its net investment income
and net realized short-term capital gains/losses, if any, as dividends daily to
its shareholders of record at the time of such declaration. Net investment
income for dividend purposes includes interest accrued or discount earned less
amortization of premium and the estimated expenses applicable to the dividend
period. Payment of dividends is made monthly. The Fund does not expect to
realize long-term capital gains or losses.
- ------------------------------------------------------------
Note 2. Agreements
The Fund has a management agreement with Prudential Investments Fund Management
LLC ('PIFM'). Pursuant to this agreement, PIFM has responsibility for all
investment advisory services and supervises the subadviser's performance of such
services. PIFM has entered into a subadvisory agreement with The Prudential
Investment Corporation ('PIC'), doing business as Prudential Investments ('PI',
the Subadviser or the investment adviser), PI furnishes investment advisory
services in connection with the management of the Fund. PIFM pays for the cost
of the subadviser's services, the compensation of officers of the Fund,
occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears
all other costs and expenses.
The management fee paid PIFM is computed daily and payable monthly, at an annual
rate of .20 of 1% of the average daily net assets of the Series. Effective June
1, 1997, PIFM has agreed to waive a portion (.05 of 1% of the Series' average
daily net assets) of its management fee, which amounted to $363,091 ($.0003 per
share) for the year ended March 31, 1998. The Series is not required to
reimburse PIFM for such waiver.
The Fund has a distribution agreement with Prudential Securities Incorporated
('PSI'), which acts as the distributor of the Class A and Class I shares of the
Fund. The Fund compensates PSI for distributing and servicing the Fund's Class A
shares, pursuant to the plan of distribution at an annual rate of .12 of 1% of
the Series' average daily net assets of the Class A shares. Effective June 1,
1997, PSI has agreed to waive a portion (.07 of 1% of the Series' average daily
net assets) of its distribution fee, which amounted to $93,005 ($.0007 per
share) for the year ended March 31, 1998. The Series is not required to
reimburse PSI for such waiver. The Class A distribution fee is accrued daily and
payable monthly. No distribution or service fees are paid to PSI as distributor
of the Class I shares of the Fund.
PSI, PIFM and PIC are indirect, wholly owned subsidiaries of The Prudential
Insurance Company of America.

PMFS. As of March 31, 1998, $20,000 of such fees were due to PMFS. Transfer
agent fees and expenses in the Statement of Operations also include certain
out-of-pocket expenses paid to nonaffiliates.
- ------------------------------------------------------------
Note 4. Expense Subsidy
Effective June 1, 1997, PIFM voluntarily agreed to subsidize operating expenses
so that total Series operating expenses do not exceed .20% and .15% of the
average daily net assets of the Class A and Class I shares, respectively. For
the year ended March 31, 1998, such reimbursement amounted to $756,061 ($0.0007
per share for Class A and I shares; .11% of average net assets, annualized).
- ------------------------------------------------------------
Note 5. Capital
The Series offers Class A and Class I shares. Class A shareholders of the Series
who qualify to purchase Class I shares will have their Class A shares exchanged
for Class I shares on a quarterly basis. Effective July 9, 1997, the Series
commenced offering Class I shares.
There are 10 billion authorized shares of common stock, $.001 par value per
share, divided into 5 billion authorized Class A shares and 5 billion authorized
Class I shares.
Transactions in shares of common stock (at $1 per share) were as follows:

     The historical performance data contained in this Appendix relies on data
obtained from statistical services, reports and other services believed by the
Manager to be reliable. The information has not been independently verified by
the Manager.

     This chart shows the long-term performance of various asset classes and the
rate of inflation.

purposes only and is not indicative of the past, present, or future performance
of any asset class or any Prudential Mutual Fund.

Generally, stock returns are due to capital appreciation and the reinvestment of
any gains. Bond returns are due mainly to reinvesting interest. Also, stock
prices are usually more volatile than bond prices over the long-term. Small
stock returns for 1926-1980 are those of stocks comprising the 5th quintile of
the New York Stock Exchange. Thereafter, returns are those of the Dimensional
Fund Advisors (DFA) Small Company Fund. Common stock returns are based on the
S&P Composite Index, a market-weighted, unmanaged index of 500 stocks
(currently) in a variety of industries. It is often used as a broad measure of
stock market performance.
    


Long-term government bond returns are measured using a constant one-bond
portfolio with a maturity of roughly 20 years. Treasury bill returns are for a
one-month bill. Treasuries are guaranteed by the government as to the timely
payment of principal and interest; equities are not. Inflation is measured by
the consumer price index (CPI).

     Set forth below is historical performance data relating to various sectors
of the fixed-income securities markets. The chart shows the historical total
returns of U.S. Treasury bonds, U.S. mortgage securities, U.S. corporate bonds,
U.S. high yield bonds and world government bonds on an annual basis from 1987
through 1997. The total returns of the indices include accrued interest, plus
the price changes (gains or losses) of the underlying securities during the
period mentioned. The data is provided to illustrate the varying historical
total returns and investors should not consider this performance data as an
indication of the future performance of a Series or of any sector in which a
Series invests.

     All information relies on data obtained from statistical services, reports
and other services believed by the Manager to be reliable. Such information has
not been verified. The figures do not reflect the operating expenses and fees of
a mutual fund. See "Series Expenses" in the applicable prospectus. The net
effect of the deduction of the operating expenses of a mutual fund on these
historical total returns, including the compounded effect over time, could be
substantial.

                   APPENDIX II-GENERAL INVESTMENT INFORMATION

     The following terms are used in mutual fund investing.

ASSET ALLOCATION

     Asset allocation is a technique for reducing risk, providing balance. Asset
allocation among different types of securities within an overall investment
portfolio helps to reduce risk and to potentially provide stable returns, while
enabling investors to work toward their financial goal(s). Asset allocation is
also a strategy to gain exposure to better performing asset classes while
maintaining investment in other asset classes.

DIVERSIFICATION

   
     Diversification is a time-honored technique for reducing risk, providing
"balance" to an overall portfolio and potentially achieving more stable returns.
Owning a portfolio of securities mitigates the individual risks (and returns) of
any one security. Additionally, diversification among types of securities
reduces the risks (and general returns) of any one type of security.
    

DURATION

     Debt securities have varying levels of sensitivity to interest rates. As
interest rates fluctuate, the value of a bond (or a bond portfolio) will
increase or decrease. Longer term bonds are generally more sensitive to changes
in interest rates. When interest rates fall, bond prices generally rise.
Conversely, when interest rates rise, bond prices generally fall.

     Duration is an approximation of the price sensitivity of a bond (or a bond
portfolio) to interest rate changes. It measures the weighted average maturity
of a bond's (or a bond portfolio's) cash flows, i.e., principal and interest
payments. Duration is expressed as a measure of time in years-the longer the
duration of a bond (or a bond portfolio), the greater the impact of interest
rate changes on the bond's (or the bond portfolio's) price. Duration differs
from effective maturity in that duration takes into account call provisions,
coupon rates and other factors. Duration measures interest rate risk only and
not other risks, such as credit risk and, in the case of non-U.S. dollar
denominated securities, currency risk. Effective maturity measures the final
maturity dates of a bond (or a bond portfolio).

MARKET TIMING

     Market timing-buying securities when prices are low and selling them when
prices are relatively higher-may not work for many investors because it is
impossible to predict with certainty how the price of a security will fluctuate.
However, owning a security for a long period of time may help investors offset
short-term price volatility and realize positive returns.

POWER OF COMPOUNDING

     Over time, the compounding of returns can significantly impact investment
returns. Compounding is the effect of continuous investment on long-term
investment results, by which the proceeds of capital appreciation (and income
distributions, if elected) are reinvested to contribute to the overall growth of
assets. The long-term investment results of compounding may be greater than that
of an equivalent initial investment in which the proceeds of capital
appreciation and income distributions are taken in cash.

INFORMATION ABOUT THE PRUDENTIAL MUTUAL FUNDS

   
     As of December 31, 1997, Prudential Investments Fund Management is the
eighteenth largest mutual fund company in the country with over 2.5 million
shareholders invested in more than 50 mutual fund portfolios and variable
annuities with more than 3.7 million shareholder accounts.
    

     The Prudential Mutual Funds have over 30 portfolio managers who manage over
$55 billion in mutual fund and variable annuity assets. Some of Prudential's
portfolio managers have over 20 years of experience managing investment
portfolios.

     From time to time, there may be media coverage of portfolio managers and
other investment professionals associated with the Manager and the Subadviser in
national and regional publications, on television and in other media.
Additionally, individual mutual fund portfolios are frequently cited in surveys
conducted by national and regional publications and media organizations such as
The Wall Street Journal, The New York Times, Barron's and USA Today.

     Equity Funds. Forbes magazine listed Prudential Equity Fund among twenty
mutual funds on its Honor Roll in its mutual fund issue of August 28, 1995.
Honorees are chosen annually among mutual funds (excluding sector funds) which
are open to new investors and have had the same management for at least five
years. Forbes considers, among other criteria, the total return of a mutual fund
in both bull and bear markets as well as a fund's risk profile. Prudential
Equity Fund is managed with a "value" investment style by PIC. In 1995,
Prudential Securities introduced Prudential Jennison Fund, a growth-style equity
fund managed by Jennison Associates Capital Corp., a premier institutional
equity manager and a subsidiary of Prudential.

     High Yield Funds. Investing in high yield bonds is a complex and research
intensive pursuit. A separate team of high yield bond analysts monitor the 167
issues held in the Prudential High Yield Fund (currently the largest fund of its
kind in the country) along with 100 or so other high yield bonds, which may be
considered for purchase.(3) Non-investment grade bonds, also known as junk bonds
or high yield bonds, are subject to a greater risk of loss of principal and
interest including default risk than higher-rated bonds. Prudential high yield
portfolio managers and analysts meet face-to-face with almost every bond issuer
in the High Yield Fund's portfolio annually, and have additional telephone
contact throughout the year.

     Prudential's portfolio managers are supported by a large and sophisticated
research organization. Fourteen investment grade bond analysts monitor the
financial viability of approximately 1,750 different bond issuers in the
investment grade corporate and municipal bond markets--from IBM to small
municipalities, such as Rockaway Township, New Jersey. These analysts consider
among other things sinking fund provisions and interest coverage ratios.

     Prudential's portfolio managers and analysts receive research services from
almost 200 brokers and market service vendors. They also receive nearly 100
trade publications and newspapers--from Pulp and Paper Forecaster to Women's
Wear Daily--to keep them informed of the industries they follow.

     Prudential Mutual Funds' traders scan over 100 computer monitors to collect
detailed information on which to trade. From natural gas prices in the Rocky
Mountains to the results of local municipal elections, a Prudential portfolio
manager or trader is able to monitor it if it's important to a Prudential mutual
fund.

     Prudential Mutual Funds trade approximately $31 billion in U.S. and foreign
government securities a year. PIC seeks information from government policy
makers. In 1995, Prudential's portfolio managers met with several senior U.S.
and foreign government officials, on issues ranging from economic conditions in
foreign countries to the viability of index-linked securities in the United
States.

     Prudential Mutual Funds' portfolio managers and analysts met with over
1,200 companies in 1995, often with the Chief Executive Officer (CEO) or Chief
Financial Officer (CFO). They also attended over 250 industry conferences.

     Prudential Mutual Fund global equity managers conducted many of their
visits overseas, often holding private meetings with a company in a foreign
language (our global equity managers speak 7 different languages, including
Mandarin Chinese).

     Trading Data.(4) On an average day, Prudential Mutual Funds' U.S. and
foreign equity trading desks traded $77 million in securities representing over
3.8 million shares with nearly 200 different firms. Prudential Mutual Funds'
bond trading desks traded $157 million in government and corporate bonds on an
average day. That represents more in daily trading than most bond funds tracked
by Lipper even have in assets.(5) Prudential Mutual Funds' money market desk
traded $3.2 billion in money market securities on an average day, or over $800
billion a year. They made a trade every 3 minutes of every trading day. In 1994,
the Prudential Mutual Funds effected more than 40,000 trades in money market
securities and held on average $20 billion of money market securities.(6)

     Based on complex-wide data, on an average day, over 7,250 shareholders
telephoned Prudential Mutual Fund Services, Inc., the Transfer Agent of the
Prudential Mutual Funds, on the Prudential Mutual Funds' toll-free number. On an
annual basis, that represents approximately 1.8 million telephone calls
answered.

ITEM 27. INDEMNIFICATION.

     As permitted by Sections 17(h) and (i) of the Investment Company Act of
1940, as amended (the 1940 Act) and pursuant to Article VII of the Registrant's
By-Laws (Exhibit 2(a) to the Registration Statement), officers, directors,
employees and agents of the Registrant will not be liable to the Registrant, any
stockholder, officer, director, employee, agent or other person for any action
or failure to act, except for bad faith, willful misfeasance, gross negligence
or reckless disregard of duties, and those individuals may be indemnified
against liabilities in connection with the Registrant, subject to the same
exceptions.Section 2-418 of Maryland General Corporation Law permits
indemnification of directors who acted in good faith and reasonably believed
that the conduct was in the best interests of the Registrant. As permitted by
Section 17(i) of the 1940 Act, pursuant to Section 10 of the Distribution
Agreements (Exhibit 6 to the Registration Statement), the Distributor of the
Registrant may be indemnified against liabilities which it may incur, except
liabilities arising from bad faith, gross negligence, willful misfeasance or
reckless disregard of duties.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (Securities Act) may be permitted to directors, 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 the 1940 Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in connection with the successful defense
of any action, suit or proceeding) is asserted against the Registrant by such
director, officer or controlling person in connection with the shares being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1940 Act and will be governed by the final
adjudication of such issue.

     The Registrant has purchased an insurance policy insuring its officers and
directors against liabilities, and certain costs of defending claims against
such officers and directors, to the extent such officers and directors are not
found to have committed conduct constituting willful misfeasance, bad faith,
gross negligence or reckless disregard in the performance of their duties. The
insurance policy also insures the Registrant against the cost of indemnification
payments to officers and directors under certain circumstances.

     Section 9 of the Management Agreements (Exhibits 5(a) and 5(c) to the
Registration Statement) and Section 4 of the Subadvisory Agreement (Exhibit 5(b)
to the Registration Statement) limit the liability of Prudential Investments
Fund Management LLC (PIFM) and The Prudential Investment Corporation (PIC),
respectively, to liabilities arising from willful misfeasance, bad faith or
gross negligence in the performance of their respective duties or from reckless
disregard by them of their respective obligations and duties under the
agreements.

     The Registrant hereby undertakes that it will apply the indemnification
provisions of its By-Laws and the Distribution Agreements in a manner consistent
with Release No. 11330 of the Securities and Exchange Commission under the 1940
Act so long as the interpretation of Sections 17(h) and 17(i) of such Act remain
in effect and are consistently applied.
