PRUDENTIAL NATURAL RESOURCES FUND, INC.
 
- -------------------------------------------------------------------------------
   
PROSPECTUS DATED JULY 30, 1997     
 
- -------------------------------------------------------------------------------
   
Prudential Natural Resources Fund, Inc. (the Fund), is an open-end,
diversified, management investment company. Its investment objective is long-
term growth of capital. It seeks to achieve this objective by investing
primarily in securities of foreign and domestic companies that own, explore,
mine, process or otherwise develop, or provide goods and services with respect
to, natural resources and in securities, the terms of which are related to the
market value of a natural resource (asset-based securities). The Fund will,
under normal circumstances, invest at least 65% of its total assets in common
stocks and equivalents (such as convertible debt securities and warrants) of
natural resource companies and in asset-based securities. The Fund may also
invest in equity securities of companies in other industries, fixed-income
securities (including money market instruments), and derivatives, including
options on equity securities, stock indices, foreign currencies and futures
contracts on foreign currencies, and may buy and sell futures contracts on
foreign currencies and on stock indices so as to hedge its portfolio. There
can be no assurance that the Fund's investment objective will be achieved. See
"How the Fund Invests--Investment Objective and Policies." The Fund's address
is Gateway Center Three, 100 Mulberry Street, Newark, New Jersey 07102-4077,
and its telephone number is (800) 225-1852.     
 
The Fund's purchase and sale of put and call options may be considered
speculative and may result in higher risks and costs to the Fund. The Fund may
also buy and sell options on stock indices pursuant to limits described
herein. See "How the Fund Invests--Investment Objective and Policies."
 
The Fund is not intended to constitute a complete investment program. Because
of its objective and policies, including its foreign investments and its
concentration in securities of natural resource companies, the Fund may be
considered of a speculative nature and subject to greater investment risks
than are assumed by certain other investment companies that invest solely in
securities of U.S. issuers or that do not concentrate their investments in
particular industries. See "How the Fund Invests--Investment Objective and
Policies--Special Considerations and Risks."
   
This Prospectus sets forth concisely the information about the Fund that a
prospective investor should know before investing. Additional information
about the Fund has been filed with the Securities and Exchange Commission in a
Statement of Additional Information, dated July 30, 1997, which information is
incorporated herein by reference (is legally considered a part of this
Prospectus) and is available without charge upon request to the Fund at the
address or telephone number noted above.     
 
- -------------------------------------------------------------------------------
Investors are advised to read this Prospectus and retain it for future
reference.
- -------------------------------------------------------------------------------
   
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR ADE-
QUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OF-
FENSE.     
<PAGE>
 
 
                                FUND 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 NATURAL RESOURCES FUND, INC.?
 
  Prudential Natural Resources Fund, Inc. is a mutual 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.
 
WHAT IS THE FUND'S INVESTMENT OBJECTIVE?
   
  The Fund's investment objective is long-term growth of capital. It seeks to
achieve this objective by investing primarily in securities of foreign and
domestic companies that own, explore, mine, process or otherwise develop, or
provide goods and services with respect to, natural resources and in
securities, the terms of which are related to the market value of a natural
resource. There can be no assurance that the Fund's objective will be achieved.
See "How the Fund Invests--Investment Objective and Policies" at page 9.     
   
WHAT ARE THE FUND'S RISK FACTORS AND SPECIAL CHARACTERISTICS?     
   
  The values of natural resources are affected by numerous factors including
events occurring in nature, inflationary pressures and international politics.
Moreover, there are no geographic limitations on natural resource companies in
which the Fund may invest; therefore, depending on market conditions, the Fund
may be invested primarily in foreign securities. See "How the Fund Invests--
Investment Objective and Policies" at page 9. In addition, the Fund may engage
in various hedging and return enhancement strategies and use derivatives. These
actions may be considered speculative and may result in higher risks and costs
to the Fund. See "How the Fund Invests--Hedging and Return Enhancement
Strategies--Risks of Hedging and Return Enhancement Strategies" at page 12. As
with an investment in any mutual fund, an investment in this Fund can decrease
in value and you can lose money.     
 
WHO MANAGES THE FUND?
   
  Prudential Investments Fund Management LLC (PIFM or the Manager) is the
Manager of the Fund and is compensated for its services at an annual rate of
 .75 of 1% of the Fund's average daily net assets. As of June 30, 1997, PIFM
served as manager or administrator to 62 investment companies, including 40
mutual funds, with aggregate assets of approximately $56.7 billion. The
Prudential Investment Corporation, which does business under the name of
Prudential Investments (PI, the Subadviser or the investment adviser),
furnishes investment advisory services in connection with the management of the
Fund under a Subadvisory Agreement with PIFM. See "How the Fund is Managed--
Manager" at page 16. The management fee is higher than that paid by most other
investment companies.     
 
WHO DISTRIBUTES THE FUND'S SHARES?
   
  Prudential Securities Incorporated (Prudential Securities or PSI), a major
securities underwriter and securities and commodities broker, acts as the
Distributor of the Fund's Class A, Class B, Class C and Class Z shares. PSI is
paid a distribution and service fee which is currently being charged at the
annual rate of .25 of 1% of the average daily net assets of the Class A shares
and is paid a distribution and service fee with respect to Class B and Class C
shares at the annual rate of 1% of the average daily net assets of each of the
Class B and Class C shares. Prudential Securities incurs the expense of
distributing the Fund's Class Z shares under a Distribution Agreement with the
Fund, none of which is reimbursed or paid for by the Fund. See "How the Fund is
Managed--Distributor" at page 17.     
 
                                       2
<PAGE>
 
 
WHAT IS THE MINIMUM INVESTMENT?
   
  The minimum initial investment for Class A and Class B shares is $1,000 per
class and $5,000 for Class C shares. The minimum subsequent investment is $100
for Class A, Class B and Class C shares. Class Z shares are not subject to any
minimum investment requirements. There is no minimum investment requirement for
certain retirement and employee savings plans or custodial accounts for the
benefit of minors. For purchases made through the Automatic Savings
Accumulation Plan, the minimum initial and subsequent investment is $50. See
"Shareholder Guide--How to Buy Shares of the Fund" at page 23 and "Shareholder
Guide--Shareholder Services" at page 34.     
 
HOW DO I PURCHASE SHARES?
   
  You may purchase shares of the Fund 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 Prudential Securities plus a sales charge which
may be imposed either (i) at the time of purchase (Class A shares) or (ii) on a
deferred basis (Class B or Class C shares). Class Z shares are offered to a
limited group of investors at net asset value without any sales charge. See
"How the Fund Values its Shares" at page 19 and "Shareholder Guide--How to Buy
Shares of the Fund" at page 23.     
   
WHAT ARE MY PURCHASE ALTERNATIVES?     
     
  The Fund offers four classes of shares through this Prospectus:     
 
  . Class A Shares:
                Sold with an initial sales charge of up to 5% of the offering
                 price.
 
  .Class B Shares:
                Sold without an initial sales charge but are subject to a
                contingent deferred sales charge or CDSC (declining from 5% to
                zero of the lower of the amount invested or the redemption
                proceeds) which will be imposed on certain redemptions made
                within six years of purchase. Although Class B shares are
                subject to higher ongoing distribution-related expenses than
                Class A shares, Class B shares will automatically convert to
                Class A shares (which are subject to lower ongoing
                distribution-related expenses) approximately seven years after
                purchase.
 
  .Class C Shares:
                Sold without an initial sales charge and, for one year after
                purchase, are subject to a 1% CDSC on redemptions. Like Class
                B shares, Class C shares are subject to higher ongoing
                distribution-related expenses than Class A shares but do not
                convert to another class.
     
  .Class Z Shares:     
                   
                Sold without either an initial or contingent deferred sales
                charge to a limited group of investors. Class Z shares are not
                subject to any ongoing service or distribution expenses.     
   
  See "Shareholder Guide--Alternative Purchase Plan" at page 24.     
 
HOW DO I SELL MY SHARES?
   
  You may redeem your shares at any time at the NAV next determined after
Prudential Securities or the Transfer Agent receives your sell order. However,
the proceeds of redemptions of Class B and Class C shares may be subject to a
CDSC. See "Shareholder Guide--How to Sell Your Shares" at page 28.     
   
HOW ARE DIVIDENDS AND DISTRIBUTIONS PAID?     
   
  The Fund expects to pay dividends of net investment income, if any, and make
distributions of any net capital gains at least annually. Dividends and
distributions will be automatically reinvested in additional shares of the Fund
at NAV without a sales charge unless you request that they be paid to you in
cash. See "Taxes, Dividends and Distributions" at page 20.

The above example is based on data for the Fund's fiscal year ended May 31,
1997. 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 this table is to assist investors in understanding the various
costs and expenses that an investor in the Fund will bear, whether directly or
indirectly. For more complete descriptions of the various costs and expenses,
see "How the Fund is Managed." "Other Expenses" includes operating expenses of
the Fund, such as Directors' and professional fees, registration fees, reports
to shareholders, transfer agency and custodian (domestic and foreign) fees and
miscellaneous fees, but excludes foreign withholding taxes.

 * Class B shares will automatically convert to Class A shares approximately
   seven years after purchase. See "Shareholder Guide--Conversion Feature--
   Class B Shares."
 + Pursuant to rules of the National Association of Securities Dealers, Inc.,
   the aggregate initial sales charges, deferred sales charges and asset-based
   sales charges on shares of the Fund may not exceed 6.25% of total gross
   sales, subject to certain exclusions. This 6.25% limitation is imposed on
   each class of the Fund rather than on a per shareholder basis. Therefore,
   long-term shareholders of the Fund may pay more in total sales charges than
   the economic equivalent of 6.25% of such shareholders' investment in such
   shares. See "How the Fund is Managed--Distributor."
   
++ Although the Class A Distribution and Service Plan provides that the Fund
   may pay a distribution fee of up to .30 of 1% per annum of the average daily
   net assets of the Class A shares, the Distributor has agreed to limit its
   distribution fees with respect to the Class A shares of the Fund to no more
   than .25 of 1% of the average daily net assets of the Class A shares for the
   fiscal year ending May 31, 1998. Total Fund Operating Expenses without such
   limitation would be 1.53%. See "How the Fund is Managed--Distributor."

                             HOW THE FUND INVESTS
 
 
INVESTMENT OBJECTIVE AND POLICIES
 
  THE INVESTMENT OBJECTIVE OF THE FUND IS LONG-TERM GROWTH OF CAPITAL. THE
FUND WILL SEEK TO ACHIEVE ITS OBJECTIVE BY INVESTING PRIMARILY IN SECURITIES
OF FOREIGN AND DOMESTIC "NATURAL RESOURCE COMPANIES" (HEREINAFTER DESCRIBED)
AND IN SECURITIES (TYPICALLY DEBT SECURITIES OR PREFERRED STOCKS) THE TERMS OF
WHICH ARE RELATED TO THE MARKET VALUE OF SOME NATURAL RESOURCE (ASSET-BASED
SECURITIES). THE FUND WILL, UNDER NORMAL CIRCUMSTANCES, INVEST AT LEAST 65% OF
ITS TOTAL ASSETS IN COMMON STOCKS AND EQUIVALENTS (SUCH AS CONVERTIBLE DEBT
SECURITIES AND WARRANTS) OF NATURAL RESOURCE COMPANIES AND IN ASSET-BASED
SECURITIES. THERE CAN BE NO ASSURANCE THAT SUCH OBJECTIVE WILL BE ACHIEVED.
 
  THE FUND'S INVESTMENT OBJECTIVE IS A FUNDAMENTAL POLICY AND, THEREFORE, MAY
NOT BE CHANGED WITHOUT THE APPROVAL OF THE HOLDERS OF A MAJORITY OF THE FUND'S
OUTSTANDING VOTING SECURITIES AS DEFINED IN THE INVESTMENT COMPANY ACT OF
1940, AS AMENDED (THE INVESTMENT COMPANY ACT). FUND POLICIES THAT ARE NOT
FUNDAMENTAL MAY BE MODIFIED BY THE BOARD OF DIRECTORS.
 
  Companies that primarily own, explore, mine, process or otherwise develop
natural resources, or supply goods and services primarily to such companies,
will be considered "natural resource companies." Natural resources generally
include precious metals (e.g., gold, silver and platinum), ferrous and
nonferrous metals (e.g., iron, aluminum and copper), strategic metals (e.g.,
uranium and titanium), hydrocarbons (e.g., coal, oil and natural gases),
timber land, undeveloped real property and agricultural commodities.
   
  THE VALUE OF EQUITY SECURITIES OF NATURAL RESOURCE COMPANIES (INCLUDING
THOSE COMPANIES THAT ARE PRIMARILY INVOLVED IN PROVIDING GOODS AND SERVICES TO
NATURAL RESOURCE COMPANIES) WILL FLUCTUATE PURSUANT TO MARKET CONDITIONS
GENERALLY, AS WELL AS THE MARKET FOR THE PARTICULAR NATURAL RESOURCE IN WHICH
THE ISSUER IS INVOLVED. IN ADDITION, THE VALUES OF NATURAL RESOURCES ARE
AFFECTED BY NUMEROUS FACTORS INCLUDING EVENTS OCCURRING IN NATURE,
INFLATIONARY PRESSURES AND INTERNATIONAL POLITICS. For instance, events in
nature (such as earthquakes or fires in prime natural resource areas) and
political events (such as coups or military confrontations) can affect the
overall supply of a natural resource and thereby the value of companies
involved in such natural resources. In addition, rising interest rates (i.e.,
inflationary pressures) may affect the demand for natural resources such as
timber. The Fund will seek securities that are attractively priced relative to
the intrinsic value of the relevant natural resource or that are of companies
which are positioned to benefit under existing or anticipated economic
conditions. Accordingly, the Fund may shift its emphasis from one natural
resource industry to another depending upon prevailing trends or developments,
provided that the Fund will not invest 25% or more of its total assets in the
securities of companies in any one natural resource industry. See "Investment
Restrictions" in the Statement of Additional Information for information
concerning industry classifications. The Fund is not required to maintain any
particular mix of investments among the natural resource industries.     
 
  THERE ARE ALSO NO GEOGRAPHIC LIMITATIONS ON NATURAL RESOURCE COMPANIES IN
WHICH THE FUND MAY INVEST. DEPENDING UPON MARKET CONDITIONS, THE FUND MAY BE
INVESTED PRIMARILY IN FOREIGN SECURITIES. In light of the geographic
concentration of many natural resources, the Fund anticipates that many of the
companies in which it invests will be located in Canada, Australia, New
Zealand, Malaysia, Western Europe, the United Kingdom and the United States.
Investments may also be made in companies located in Indonesia, Japan, other
countries in Southeast Asia and other countries as the Fund's investment
adviser may from time to time determine. In connection with the Fund's
investments in foreign securities, the Fund's investment adviser will consider
factors such as the expected levels of inflation and interest rates;
government policies influencing business conditions; the range of investment
opportunities available to international
 
                                       9
<PAGE>
 
investors and other pertinent financial, tax, social, political and national
factors--all in relation to the prevailing prices of the securities of foreign
issuers. The Fund may seek to hedge its position in foreign currencies as more
fully described herein.
   
  THE FUND IS NOT REQUIRED TO MAINTAIN ANY PARTICULAR GEOGRAPHIC OR CURRENCY
MIX OF ITS INVESTMENTS; HOWEVER, WHEN MARKET CONDITIONS WARRANT, THE FUND MAY
BE PRIMARILY INVESTED IN SECURITIES OF U.S. ISSUERS.     
   
  AS WITH AN INVESTMENT IN ANY MUTUAL FUND, AN INVESTMENT IN THIS FUND CAN
DECREASE IN VALUE AND YOU CAN LOSE MONEY.     
   
  THE FUND MAY INVEST IN COMMON STOCK EQUIVALENTS, SUCH AS CONVERTIBLE
SECURITIES, AS WELL AS IN COMMON STOCKS. A convertible security is a fixed-
income security (a bond or preferred stock) which may be converted at a stated
price within a specified period of time into a certain quantity of the common
stock of the same or a different issuer. Convertible securities are senior to
common stocks in a corporation's capital structure, but are usually
subordinated to similar nonconvertible securities. While providing a fixed
income stream (generally higher in yield than the income stream derivable from
a common stock but lower than that afforded by a similar nonconvertible
security), a convertible security also affords an investor the opportunity,
through its conversion feature, to participate in the capital appreciation
attendant upon a market price advance in the convertible security's underlying
common stock.     
 
  The price of a convertible security tends to increase as the market value of
the underlying stock rises, whereas it tends to decrease as the market value
of the underlying stock declines. While no securities investment is without
some risk, investments in convertible securities generally entail less risk
than investments in the common stock of the same issuer.
   
  IN ADDITION TO COMMON STOCKS AND COMMON STOCK EQUIVALENTS, THE FUND MAY
INVEST IN SECURITIES, THE PRINCIPAL AMOUNT, REDEMPTION TERMS OR CONVERSION
TERMS OF WHICH ARE RELATED TO THE MARKET PRICE OF A NATURAL RESOURCE, REFERRED
TO HEREIN AS "ASSET-BASED SECURITIES." The Fund will only purchase asset-based
securities which are rated, or are issued by issuers that have outstanding
obligations rated, at least BBB or Baa by Standard & Poor's Ratings Group
(S&P) or Moody's Investors Service, Inc. (Moody's), respectively, or
commercial paper rated at least A-2 or P-2 by S&P or Moody's, respectively, or
comparably rated by a nationally recognized statistical rating organization
(NRSRO) or, if unrated, unrated securities of issuers that the investment
adviser has determined to be of comparable quality. Subsequent to its purchase
by the Fund, a security may be assigned a lower rating or cease to be rated.
Such an event would not require the elimination of the issue from the
portfolio, but the investment adviser will consider such an event in
determining whether the Fund should continue to hold the security in its
portfolio. Securities rated Baa by Moody's, although considered to be
investment grade, lack outstanding investment characteristics and, in fact,
have speculative characteristics. See "Description of Security Ratings" in the
Statement of Additional Information. If the asset-based security is backed by
a letter of credit or other similar instrument, the Fund's investment adviser
may take such backing into account in determining the quality of the security.
    
  Although it is expected that the market prices of the asset-based securities
will fluctuate on the basis of the natural resources on which such securities
are based, there may not be a perfect correlation between the price movements
of the asset-based securities and the underlying natural resources. Asset-
based securities are not always secured with a security interest in the
underlying natural resource asset. Further, asset-based securities typically
bear interest or pay dividends at below market rates (and in certain cases at
nominal rates). Although the value of asset-based securities that bear
interest may fluctuate inversely with market interest rates, such fluctuations
are anticipated generally to be minimal since the value of such securities is
typically based on the natural resources on which the securities are based.
 
  Certain asset-based securities may be payable at maturity in cash, or, at
the option of the holder, directly in a stated amount of the asset to which
the securities are related. The Fund does not intend to invest directly in
natural resources and, therefore, would elect to be paid in cash or would sell
the asset-based security prior to maturity to realize the appreciation in the
underlying asset. An example of an asset-based security would be a debt
security that will be repaid at a price based on, for instance, gold or crude
oil prices over a specified period of time. Assume, for example, that gold is
selling at a market price of $300 per ounce and an issuer sells a $1,000 face
amount gold-related note with a four year
 
                                      10
<PAGE>
 
   
maturity, payable at maturity in cash at the greater of either $1,000 or the
then market price of three ounces of gold. If at maturity the market price of
gold is $400 per ounce, the amount payable on the note would be $1,200.     
   
  AS INDICATED ABOVE, THE FUND INTENDS TO INVEST PRIMARILY IN COMMON STOCKS
AND EQUIVALENTS OF NATURAL RESOURCE COMPANIES AND ASSET-BASED SECURITIES;
HOWEVER, UNDER NORMAL CIRCUMSTANCES, THE FUND MAY INVEST UP TO 35% OF ITS
TOTAL ASSETS IN COMMON STOCKS (AND EQUIVALENTS) OF COMPANIES OTHER THAN
NATURAL RESOURCE COMPANIES AND IN DEBT SECURITIES OF NATURAL RESOURCE
COMPANIES, AS WELL AS OTHER COMPANIES. The Fund will only invest in debt
securities (including money market instruments) of such companies which are
rated, or are issued by companies that have outstanding debt securities rated,
at least BBB or Baa by S&P or Moody's, respectively, or commercial paper rated
at least A-2 or Prime-2 by S&P or Moody's, respectively, or comparably rated
by a nationally recognized statistical rating organization (NRSRO) or if
unrated, unrated securities of issuers that the investment adviser has
determined to be of comparable quality. Money market instruments include
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities, commercial paper, certificates of deposit, bankers'
acceptances and other obligations of domestic and foreign banks (and branches
thereof). See "Description of Security Ratings" in the Statement of Additional
Information. Unlike equity securities, there may not be a direct correlation
between the price of debt securities of a natural resource company and the
demand for the natural resource assets of the company. In addition, the prices
of debt securities generally increase when interest rates decline and decrease
when interest rates rise.     
 
  THE FUND MAY ALSO (I) ENTER INTO FORWARD FOREIGN CURRENCY EXCHANGE
CONTRACTS, (II) PURCHASE AND WRITE (I.E., SELL) PUT AND CALL OPTIONS ON
STOCKS, STOCK INDICES AND FOREIGN CURRENCIES, (III) PURCHASE AND SELL FUTURES
CONTRACTS ON FOREIGN CURRENCIES AND STOCK INDICES, (IV) PURCHASE SECURITIES ON
A WHEN-ISSUED OR DELAYED DELIVERY BASIS, (V) MAKE SHORT SALES AGAINST-THE-BOX
AND (VI) ENTER INTO REPURCHASE AGREEMENTS.
 
  WHEN CONDITIONS DICTATE A TEMPORARY DEFENSIVE STRATEGY OR DURING PERIODS OF
PORTFOLIO STRUCTURING AND RESTRUCTURING, THE FUND MAY INVEST IN MONEY MARKET
INSTRUMENTS WITHOUT LIMIT.
 
  IN MANAGING THE FUND'S PORTFOLIO, THE PORTFOLIO MANAGER SEEKS TO IDENTIFY
BROAD TRENDS IN THE NATURAL RESOURCES INDUSTRY THAT, IN HIS OPINION, MAY
PROVIDE ATTRACTIVE INVESTMENT OPPORTUNITIES, EMPHASIZING COMPANIES THAT ARE
LOWER-COST PRODUCERS IN THEIR INDUSTRIES. THE CURRENT PORTFOLIO MANAGER
FOLLOWS A "CONTRARIAN" INVESTMENT APPROACH AND MAY PURCHASE SECURITIES THAT
ARE OUT OF FAVOR WITH MANY INVESTORS OR SELL SECURITIES THAT ARE CURRENTLY IN
FAVOR WITH MANY INVESTORS. SEE "HOW THE FUND IS MANAGED--MANAGER."
 
  SPECIAL CONSIDERATIONS AND RISKS
 
  FOREIGN SECURITIES INVOLVE CERTAIN RISKS WHICH SHOULD BE CONSIDERED
CAREFULLY BY AN INVESTOR IN THE FUND. THESE RISKS INCLUDE POLITICAL OR
ECONOMIC INSTABILITY IN THE COUNTRY OF THE ISSUER, THE DIFFICULTY OF
PREDICTING INTERNATIONAL TRADE PATTERNS, THE POSSIBILITY OF IMPOSITION OF
EXCHANGE CONTROLS AND THE RISK OF CURRENCY FLUCTUATIONS. Such securities may
be subject to greater fluctuations in price than securities issued by U.S.
corporations or issued or guaranteed by the U.S. Government, its
instrumentalities or agencies. In addition, there may be less publicly
available information about a foreign company than about a domestic company.
Foreign companies generally are not subject to uniform accounting, auditing
and financial reporting standards comparable to those applicable to domestic
companies. There is generally less government regulation of securities
exchanges, brokers and listed companies abroad than in the United States, and,
with respect to certain foreign countries, there is a possibility of
expropriation, confiscatory taxation or diplomatic developments which could
affect investments in those countries. Finally, in the event of a default on
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.
 
  In many instances, foreign debt securities may provide higher yields than
securities of domestic issuers which have similar maturities and are of
similar quality. Under certain market conditions these investments may be less
liquid than the securities of U.S. corporations and are certainly less liquid
than securities issued or guaranteed by the U.S. Government, its
instrumentalities or agencies.
 
                                      11
<PAGE>
 
  IF A SECURITY IS DENOMINATED IN A FOREIGN CURRENCY, IT WILL BE AFFECTED BY
CHANGES IN CURRENCY EXCHANGE RATES AND IN EXCHANGE CONTROL REGULATIONS, AND
COSTS WILL BE INCURRED IN CONNECTION WITH CONVERSIONS BETWEEN CURRENCIES. A
change in the value of any such currency against the U.S. dollar will result
in a corresponding change in the U.S. dollar value of the Fund's securities
denominated in that currency. Such changes also will affect the Fund's income
and distributions to shareholders. In addition, although the Fund will receive
income in such currencies, the Fund will be required to compute and distribute
its income in U.S. dollars. Therefore, if the exchange rate for any such
currency declines after the Fund's income has been accrued and translated into
U.S. dollars, the Fund could be required to liquidate portfolio securities to
make such distributions, particularly in instances in which the amount of
income the Fund is required to distribute is not immediately reduced by the
decline in such currency. Similarly, if an exchange rate declines between the
time the Fund incurs expenses in U.S. dollars and the time such expenses are
paid, the amount of such currency required to be converted into U.S. dollars
in order to pay such expenses in U.S. dollars will be greater than the
equivalent amount in any such currency of such expenses at the time they were
incurred. The Fund may enter into forward foreign currency exchange contracts
for the purchase or sale of foreign currency, may purchase and sell futures
contracts on foreign currencies and may purchase and write put and call
options on foreign currencies and on futures contracts on foreign currencies.
 
HEDGING AND RETURN ENHANCEMENT STRATEGIES
   
  THE FUND MAY ENGAGE IN VARIOUS PORTFOLIO STRATEGIES, INCLUDING PURCHASING
AND SELLING DERIVATIVES, TO REDUCE CERTAIN RISKS OF ITS INVESTMENTS AND TO
ATTEMPT TO ENHANCE RETURN, BUT NOT FOR SPECULATION. THESE STRATEGIES CURRENTLY
INCLUDE THE USE OF OPTIONS, FORWARD CURRENCY EXCHANGE CONTRACTS AND FUTURES
CONTRACTS AND OPTIONS THEREON. The Fund, and thus an investor, may lose money
through unsuccessful use of these strategies. The Fund's ability to use these
strategies may be limited by market conditions, regulatory limits and tax
considerations and there can be no assurance that any of these strategies will
succeed. See "Investment Objective and Policies" and "Taxes, Dividends and
Distributions" in the Statement of Additional Information. New financial
products and risk management techniques continue to be developed and the Fund
may use these new investments and techniques to the extent consistent with its
investment objective and policies.     
 
  OPTIONS TRANSACTIONS
 
  THE FUND MAY PURCHASE AND WRITE (I.E., SELL) PUT AND CALL OPTIONS ON
SECURITIES AND CURRENCIES THAT ARE TRADED ON NATIONAL OR FOREIGN SECURITIES
EXCHANGES OR IN THE OVER-THE-COUNTER MARKET TO ATTEMPT TO ENHANCE RETURN OR TO
HEDGE THE FUND'S PORTFOLIO. These options will be on equity securities,
financial indices (e.g., S&P 500) and foreign currencies. The Fund may write
covered put and call options to generate additional income through the receipt
of premiums, purchase put options in an effort to protect the value of a
security that it owns against a decline in market value and purchase call
options in an effort to protect against an increase in the price of securities
(or currencies) it intends to purchase. The Fund may also purchase put and
call options to offset previously written put and call options of the same
series. See "Investment Objective and Policies--Options Transactions" in the
Statement of Additional Information.
   
  A CALL OPTION GIVES THE PURCHASER, IN EXCHANGE FOR A PREMIUM PAID, THE
RIGHT, FOR A SPECIFIED PERIOD OF TIME, TO PURCHASE THE SECURITIES OR CURRENCY
SUBJECT TO THE OPTION AT A SPECIFIED PRICE (THE EXERCISE PRICE OR STRIKE
PRICE). The writer of a call option, in return for the premium, has the
obligation, upon exercise of the option, to deliver, depending upon the terms
of the option contract, the underlying securities or currency or a specified
amount of cash to the purchaser upon receipt of the exercise price. When the
Fund writes a call option, it gives up the potential for gain on the
underlying securities or currency in excess of the exercise price of the
option during the period that the option is open.     
 
  A PUT OPTION GIVES THE PURCHASER, IN RETURN FOR A PREMIUM, THE RIGHT, FOR A
SPECIFIED PERIOD OF TIME, TO SELL THE SECURITIES OR CURRENCY SUBJECT TO THE
OPTION TO THE WRITER OF THE PUT AT THE SPECIFIED EXERCISE PRICE. The writer of
the put option, in return for the premium, has the obligation, upon exercise
of the option, to acquire the securities or currency
 
                                      12
<PAGE>
 
underlying the option or deliver cash at the exercise price. The Fund might,
therefore, be obligated to purchase the underlying securities or currency for
more than their current market price.
   
  THE FUND WILL WRITE ONLY "COVERED" OPTIONS. A written option is "covered"
if, as long as the Fund is obligated under the option, it (i) owns an
offsetting position in the underlying security or currency or (ii) maintains
in a segregated account, cash or other liquid assets in an amount equal to or
greater than its obligation under the option. There is no limitation on the
amount of call options the Fund may write. See "Investment Objective and
Policies--Options Transactions" in the Statement of Additional Information.
    
       
  FORWARD CURRENCY EXCHANGE CONTRACTS
 
  THE FUND MAY ENTER INTO FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS TO
PROTECT THE VALUE OF ITS PORTFOLIO AGAINST FUTURE CHANGES IN THE LEVEL OF
CURRENCY EXCHANGE RATES. The Fund may enter into such contracts on a spot,
i.e., cash, basis at the rate then prevailing in the currency exchange market
or on a forward basis, by entering into a forward contract to purchase or sell
currency. A forward contract on foreign currency is an obligation to purchase
or sell a specific currency at a future date, which may be any fixed number of
days agreed upon by the parties from the date of the contract at a price set
on the date of the contract.
 
  THE FUND'S DEALINGS IN FORWARD CONTRACTS WILL BE LIMITED TO HEDGING
INVOLVING EITHER SPECIFIC TRANSACTIONS OR PORTFOLIO POSITIONS. Transaction
hedging is the purchase or sale of a forward contract with respect to specific
receivables or payables of the Fund generally arising in connection with the
purchase or sale of its portfolio securities and accruals of interest or
dividends receivable and Fund expenses. Position hedging is the sale of a
foreign currency with respect to portfolio security positions denominated or
quoted in that currency or in a currency bearing a substantial correlation to
the value of that currency (cross hedge). Although there are no limits on the
number of forward contracts which the Fund may enter into, the Fund may not
position hedge with respect to a particular currency for an amount greater
than the aggregate market value (determined at the time of making any sale of
foreign currency) of the securities held in its portfolio denominated or
quoted in, or currently convertible into, such currency. See "Investment
Objective and Policies--Risks Related to Forward Currency Exchange Contracts"
in the Statement of Additional Information.
 
  FUTURES CONTRACTS AND OPTIONS THEREON
   
  THE FUND MAY PURCHASE AND SELL FINANCIAL FUTURES CONTRACTS AND OPTIONS
THEREON WHICH ARE TRADED ON A COMMODITIES EXCHANGE OR BOARD OF TRADE FOR
CERTAIN HEDGING AND RISK MANAGEMENT PURPOSES AND TO ATTEMPT TO ENHANCE RETURN
IN ACCORDANCE WITH REGULATIONS OF THE COMMODITY FUTURES TRADING COMMISSION.
The Fund, and thus an investor, may lose money through unsuccessful use of
these strategies. These futures contracts and options thereon will be on
financial indices and foreign currencies or groups of foreign currencies such
as the European Currency Unit. (A European Currency Unit is a basket of
specified amounts of the currencies of certain member states of the European
Economic Community, a Western European economic cooperative organization
including such countries as France, Germany, The Netherlands and the United
Kingdom.) A financial futures contract is an agreement to purchase or sell an
agreed amount of securities or currencies at a set price for delivery in the
future.     
 
  Under regulations of the Commodity Exchange Act, investment companies
registered under the Investment Company Act are exempt from the definition of
"commodity pool operator," subject to compliance with certain conditions. The
exemption is conditioned upon the Fund's purchasing and selling futures
contracts and options thereon for bona fide hedging transactions, except that
the Fund may purchase and sell futures contracts and options thereon for any
other purpose to the extent that the aggregate initial margin and option
premiums do not exceed 5% of the liquidation value of the Fund's total assets.
Although there are no other limits applicable to futures contracts, the value
of all futures contracts sold will not exceed the total market value of the
Fund's portfolio.
 
  THE FUND'S SUCCESSFUL USE OF FUTURES CONTRACTS AND OPTIONS THEREON DEPENDS
UPON THE INVESTMENT ADVISER'S ABILITY TO PREDICT THE DIRECTION OF THE MARKET
AND OF INTEREST RATES AND REQUIRES SKILLS AND TECHNIQUES DIFFERENT FROM
 
                                      13
<PAGE>
 
THOSE USED IN SELECTING PORTFOLIO SECURITIES. The correlation between
movements in the price of a futures contract and movements in the index or
price of the currencies being hedged is imperfect and there is a risk that the
value of the index or currencies being hedged may increase or decrease at a
greater rate than the related futures contracts resulting in losses to the
Fund. Certain futures exchanges or boards of trade have established daily
limits on the amount that the price of futures contracts or options thereon
may vary, either up or down, from the previous day's settlement price. These
daily limits may restrict the Fund's ability to purchase or sell certain
futures contracts or options thereon on any particular day.
   
  THE FUND'S ABILITY TO ENTER INTO OR CLOSE OUT FUTURES CONTRACTS AND OPTIONS
THEREON IS LIMITED BY THE REQUIREMENTS OF THE INTERNAL REVENUE CODE OF 1986,
AS AMENDED (THE INTERNAL REVENUE CODE), FOR QUALIFICATION AS A REGULATED
INVESTMENT COMPANY. See "Taxes, Dividends and Distributions" in the Statement
of Additional Information.     
 
  RISKS OF HEDGING AND RETURN ENHANCEMENT STRATEGIES
   
  PARTICIPATION IN THE OPTIONS OR FUTURES MARKETS AND IN CURRENCY EXCHANGE
TRANSACTIONS INVOLVES INVESTMENT RISKS AND TRANSACTION COSTS TO WHICH THE FUND
WOULD NOT BE SUBJECT ABSENT THE USE OF THESE STRATEGIES. The Fund, and thus an
investor, may lose money through any unsuccessful use of these strategies. If
the investment adviser's predictions of movements in the direction of the
securities, foreign currency and interest rate markets are inaccurate, the
adverse consequences to the Fund may leave the Fund in a worse position than
if such strategies were not used. Risks inherent in the use of options,
foreign currency and futures contracts and options thereon include (1)
dependence on the investment adviser's ability to predict correctly movements
in the direction of interest rates, securities prices and currency markets;
(2) imperfect correlation between the price of options and futures contracts
and options thereon and movements in the prices of the securities or
currencies being hedged; (3) the fact that skills needed to use these
strategies are different from those needed to select portfolio securities; (4)
the possible absence of a liquid secondary market for any particular
instrument at any time; (5) the possible need to defer closing out certain
hedged positions to avoid adverse tax consequences; and (6) the possible
inability of the Fund to purchase or sell a portfolio security at a time that
otherwise would be favorable for it to do so, or the possible need for the
Fund to sell a portfolio security at a disadvantageous time, due to the need
for the Fund to maintain "cover" or to segregate securities in connection with
hedging transactions. See "Investment Objective and Policies" and "Taxes,
Dividends and Distributions" in the Statement of Additional Information.     
 
OTHER INVESTMENTS AND POLICIES
     
  WHEN-ISSUED OR DELAYED DELIVERY SECURITIES     
   
  The Fund may purchase or sell securities on a when-issued or delayed
delivery basis. When-issued or delayed delivery transactions arise when
securities are purchased or sold by the Fund 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 Fund at the time of entering into the
transaction. The Fund's Custodian will maintain, in a segregated account of
the Fund, cash, U.S. Government securities, equity securities or other liquid,
unencumbered assets, marked-to-market daily, having a value equal to or
greater than the Fund's purchase commitments. The securities so purchased are
subject to market fluctuation and no interest accrues to the purchaser during
the period between purchase and settlement. At the time of delivery of the
securities the value may be more or less than the purchase price and an
increase in the percentage of the Fund's assets committed to the purchase of
securities on a when-issued or delayed delivery basis may increase the
volatility of the Fund's net asset value.     
 
  REPURCHASE AGREEMENTS
 
  The Fund may on occasion enter into repurchase agreements whereby the seller
of a security agrees to repurchase that security from the Fund at a mutually
agreed upon time and price. The repurchase date is usually quite short,
possibly overnight or a few days, although it may extend over a number of
months. The resale price is in excess of the purchase
 
                                      14
<PAGE>
 
   
price, reflecting an agreed-upon rate of return effective for the period of
time the Fund's money is invested in the repurchase agreement. The Fund's
repurchase agreements will at all times be fully collateralized in an amount
at least equal to the resale price. The instruments held as collateral are
valued daily, and if the value of the instruments declines, the Fund will
require additional collateral. If the seller defaults and the value of the
collateral securing the repurchase agreement declines, the Fund may incur a
loss. The Fund participates in a joint repurchase account with other
investment companies managed by Prudential Investments Fund Management LLC
pursuant to an order of the Securities and Exchange Commission (SEC).     
 
  ILLIQUID SECURITIES
   
  The Fund may hold up to 15% of its net assets in illiquid securities,
including repurchase agreements which have a maturity of longer than seven
days, securities with legal or contractual restrictions on resale (restricted
securities) and securities that are not readily marketable in securities
markets either within or outside of the United States. 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. The
Fund's investment in Rule 144A securities could have the effect of increasing
illiquidity to the extent that qualified institutional buyers become, for a
limited time, uninterested in purchasing Rule 144A securities. See "Investment
Objective and Policies--Illiquid Securities" in the Statement of Additional
Information. Repurchase agreements subject to demand are deemed to have a
maturity equal to the applicable notice period.     
       
  BORROWING
   
  The Fund may borrow an amount equal to no more than 20% of the value of its
total assets (computed at the time the loan is made) for temporary,
extraordinary or emergency purposes or for the clearance of transactions. The
Fund may pledge up to 20% of its total assets to secure these borrowings. If
the Fund borrows to invest in securities, any investment gains made on the
securities in excess of interest paid on the borrowing will cause the net
asset value of the shares to rise faster than would otherwise be the case. On
the other hand, if the investment performance of the additional securities
purchased fails to cover their cost (including any interest paid on the money
borrowed) to the Fund, the net asset value of the Fund's shares will decrease
faster than would otherwise be the case. This is the speculative factor known
as "leverage." See "Investment Restrictions" in the Statement of Additional
Information.     
 
  SHORT SALES AGAINST-THE-BOX
   
  The Fund may make short sales of securities or maintain a short position,
provided that at all times when a short position is open the Fund owns an
equal amount of such securities or securities convertible into or
exchangeable, without payment of any further consideration, for an equal
amount of the securities of the same issuer as the securities sold short (a
short sale against-the-box), and that not more than 25% of the Fund's net
assets (determined at the time of the short sale) may be subject to such
sales. Short sales will be made primarily to defer realization of gain or loss
for federal tax purposes. The Fund does not intend to have more than 5% of its
net assets (determined at the time of the short sale) subject to short sales
against-the-box during the coming year.     
 
  SECURITIES LENDING
          
  The Fund may lend its portfolio securities to brokers or dealers, banks or
other recognized institutional borrowers of securities, provided that the
borrower at all times maintains cash or other liquid assets or secures an
irrevocable letter of credit in favor of the Fund in an amount equal to at
least 100%, determined daily, of the market value of the securities loaned
which are maintained in a segregated account pursuant to applicable
regulations. During the time portfolio securities     
 
                                      15
<PAGE>
 
   
are on loan, the borrower will pay the Fund an amount equivalent to any
dividend or interest paid on such securities and the Fund may invest the cash
collateral and earn additional income, or it may receive an agreed-upon amount
of interest income from the borrower. As a matter of fundamental policy, the
Fund cannot lend more than 30% of the value of its total assets. The Fund may
pay reasonable administration and custodial fees in connection with a loan.
See "Investment Objective and Policies--Lending of Portfolio Securities" in
the Statement of Additional Information.     
 
  PORTFOLIO TURNOVER
 
  As a result of the Fund's investment policies, its portfolio turnover rate
may exceed 100%, although the rate is not expected to exceed 200%. The
portfolio turnover rate is calculated by dividing the lesser of sales or
purchases of portfolio securities by the average monthly value of the Fund's
portfolio securities, excluding securities having a maturity at the date of
purchase of one year or less. High portfolio turnover may involve
correspondingly greater brokerage commissions and other transaction costs,
which will be borne directly by the Fund. See "Portfolio Transactions and
Brokerage" in the Statement of Additional Information. In addition, high
portfolio turnover may result in increased short-term capital gains which,
when distributed to shareholders, are treated as ordinary income. See "Taxes,
Dividends and Distributions."
 
INVESTMENT RESTRICTIONS
 
  The Fund 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
Fund's outstanding voting securities, as defined in the Investment Company
Act. See "Investment Restrictions" in the Statement of Additional Information.
 
 
                            HOW THE FUND IS MANAGED
 
 
  THE FUND HAS A BOARD OF DIRECTORS WHICH, IN ADDITION TO OVERSEEING THE
ACTIONS OF THE FUND'S MANAGER, SUBADVISER AND DISTRIBUTOR, AS SET FORTH BELOW,
DECIDES UPON MATTERS OF GENERAL POLICY. THE FUND'S MANAGER CONDUCTS AND
SUPERVISES THE DAILY BUSINESS OPERATIONS OF THE FUND. THE FUND'S SUBADVISER
FURNISHES DAILY INVESTMENT ADVISORY SERVICES.
   
  For the fiscal year ended May 31, 1997, and, in the case of the Class Z
Shares, the period ended May 31, 1997, the Fund's total expenses as a
percentage of average net assets for the Fund's Class A, Class B, Class C and
Class Z shares were 1.48%, 2.23%, 2.23% and 1.23%, respectively. 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 FUND AND IS COMPENSATED FOR ITS SERVICES AT AN ANNUAL RATE OF
 .75 OF 1% OF THE FUND'S AVERAGE DAILY NET ASSETS. PIFM is organized in New
York as a limited liability company. It is the successor of Prudential Mutual
Fund Management, Inc., which transferred its assets to PIFM in September 1996.
For the fiscal year ended May 31, 1997, the Fund paid management fees to PIFM
of .75 of 1% of the Fund's average net assets. See "'Manager" in the Statement
of Additional Information.     
   
  As of June 30, 1997, PIFM served as the manager to 40 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 $56.7 billion.     
   
  UNDER THE MANAGEMENT AGREEMENT WITH THE FUND, PIFM MANAGES THE INVESTMENT
OPERATIONS OF THE FUND AND ALSO ADMINISTERS THE FUND'S CORPORATE AFFAIRS. See
"Manager" in the Statement of Additional Information.     
 
                                      16

  PURSUANT TO A SUBADVISORY AGREEMENT BETWEEN PIFM AND PRUDENTIAL INVESTMENT
CORPORATION (PIC), 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 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.     
   
  The current portfolio manager of the Fund is Leigh Goehring, a manager of
PI. Mr. Goehring has responsibility for the day-to-day management of the
Fund's portfolio. Mr. Goehring has been employed by PI as a manager since
1986. Mr. Goehring also serves as the portfolio manager of the National
Resources Portfolio within Prudential's variable life and annuity products.
       
  PIFM and PIC are wholly-owned subsidiaries of Prudential, a major
diversified insurance and financial services company.     
 
DISTRIBUTOR
 
  PRUDENTIAL SECURITIES INCORPORATED (PRUDENTIAL SECURITIES OR PSI), ONE
SEAPORT PLAZA, NEW YORK, NEW YORK 10292, IS A CORPORATION ORGANIZED UNDER THE
LAWS OF THE STATE OF DELAWARE AND SERVES AS THE DISTRIBUTOR OF THE SHARES OF
THE FUND. IT IS AN INDIRECT, WHOLLY-OWNED SUBSIDIARY OF PRUDENTIAL.
   
  UNDER SEPARATE DISTRIBUTION AND SERVICE PLANS (THE CLASS A PLAN, THE CLASS B
PLAN AND THE CLASS C PLAN, COLLECTIVELY, THE PLANS) ADOPTED BY THE FUND UNDER
RULE 12B-1 UNDER THE INVESTMENT COMPANY ACT AND A DISTRIBUTION AGREEMENT (THE
DISTRIBUTION AGREEMENT), PRUDENTIAL SECURITIES (THE DISTRIBUTOR) INCURS THE
EXPENSES OF DISTRIBUTING THE FUND'S CLASS A, CLASS B AND CLASS C SHARES.
Prudential Securities also incurs the expense of distributing the Fund's Class
Z shares under the Distribution Agreement, none of which is reimbursed or paid
for by the Fund. These expenses include commissions and 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, commissions and 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 Prudential Securities and Prusec associated
with the sale of Fund shares, including lease, utility, communications and
sales promotion expenses.     
       
  Under the Plans, the Fund is obligated to pay distribution and/or service
fees to the Distributor as compensation for its distribution and service
activities, not as reimbursement for specific expenses incurred. If the
Distributor's expenses exceed its distribution and service fees, the Fund will
not be obligated to pay any additional expenses. If the Distributor's expenses
are less than such distribution and service fees, it will retain its full fees
and realize a profit.
   
  UNDER THE CLASS A PLAN, THE FUND MAY PAY PRUDENTIAL SECURITIES FOR ITS
DISTRIBUTION-RELATED ACTIVITIES WITH RESPECT TO CLASS A SHARES AT AN ANNUAL
RATE OF UP TO .30 OF 1% OF THE AVERAGE DAILY NET ASSETS OF THE CLASS A SHARES.
The Class A Plan provides that (i) up to .25 of 1% of the average daily net
assets of the Class A shares may be used to pay for personal service and/or
the maintenance of shareholder accounts (service fee) and (ii) total
distribution fees (including the service fee of .25 of 1%) may not exceed .30
of 1% of the average daily net assets of the Class A shares. Prudential
Securities has agreed to limit its distribution-related fees payable under the
Class A Plan to .25 of 1% of the average daily net assets of the Class A
shares for the fiscal year ending May 31, 1998.     
 
  UNDER THE CLASS B AND CLASS C PLANS, THE FUND PAYS PRUDENTIAL SECURITIES FOR
ITS DISTRIBUTION-RELATED ACTIVITIES WITH RESPECT TO CLASS B AND CLASS C SHARES
AT AN ANNUAL RATE OF UP TO 1% OF THE AVERAGE DAILY NET ASSETS OF EACH OF THE
CLASS B AND CLASS C SHARES. The Class B and Class C Plans provide for the
payment to Prudential Securities of (i) an asset-based sales charge of .75 of
1% of the average daily net assets of each of the Class B and Class C shares
 
                                      17
<PAGE>
 
and (ii) a service fee of .25 of 1% of the average daily net assets of each of
the Class B and Class C shares. The service fee is used to pay for personal
service and/or the maintenance of shareholder accounts. Prudential Securities
also receives contingent deferred sales charges from certain redeeming
shareholders. See "Shareholder Guide--How to Sell Your Shares--Contingent
Deferred Sales Charges."
   
  For the fiscal year ended May 31, 1997, the Fund paid distribution expenses
of .25 of 1%, 1.00% and 1.00% of the average daily net assets of the Class A,
Class B and Class C shares, respectively. The Fund records all payments made
under the Plans as expenses in the calculation of net investment income. See
"Distributor" in the Statement of Additional Information.     
   
  Distribution expenses attributable to the sale of Class A, Class B or Class
C shares of the Fund will be allocated to each such class based upon the ratio
of sales of each such class to the sales of Class A, Class B or Class C shares
of the Fund other than expenses allocable to a particular class. The
distribution fee and sales charge of one class will not be used to subsidize
the sale of another class.     
 
  Each Plan provides that it shall continue in effect from year to year
provided that a majority of the Board of Directors of the Fund, including a
majority of the Directors who are not "interested persons" of the Fund (as
defined in the Investment Company Act) and who have no direct or indirect
financial interest in the operation of the Plan or any agreement related to
the Plan (the Rule 12b-1 Directors), vote annually to continue the Plan. Each
Plan may be terminated at any time by vote of a majority of the Rule 12b-1
Directors or of a majority of the outstanding shares of the applicable class
of the Fund. The Fund will not be obligated to pay distribution and service
fees incurred under any Plan if it is terminated or not continued.
   
  In addition to distribution and service fees paid by the Fund under the
Class A, Class B and Class C Plans, the Manager (or one of its affiliates) may
make payments out of its own resources to dealers (including Prudential
Securities) and other persons who distribute shares of the Fund (including
Class Z shares). Such payments may be calculated by reference to the net asset
value of shares sold by such persons or otherwise.     
 
  The Distributor is subject to the rules of the National Association of
Securities Dealers, Inc. (NASD), governing maximum sales charges. See
"Distributor" in the Statement of Additional Information.
   
  On October 21, 1993, PSI entered into an omnibus settlement with the SEC,
state securities regulators (with the exception of the Texas Securities
Commissioner who joined the settlement on January 18, 1994) and the NASD to
resolve allegations that from 1980 through 1990 PSI sold certain limited
partnership interests in violation of securities laws to persons for whom such
securities were not suitable and misrepresented the safety, potential returns
and liquidity of these investments. Without admitting or denying the
allegations asserted against it, PSI consented to the entry of an SEC
Administrative Order which stated that PSI's conduct violated the federal
securities laws, directed PSI to cease and desist from violating the federal
securities laws, pay civil penalties, and adopt certain remedial measures to
address the violations.     
 
  Pursuant to the terms of the SEC settlement, PSI agreed to the imposition of
a $10,000,000 civil penalty, established a settlement fund in the amount of
$330,000,000 and procedures to resolve legitimate claims for compensatory
damages by purchasers of the partnership interests. PSI has agreed to provide
additional funds, if necessary, for the purpose of the settlement fund. PSI's
settlement with the state securities regulators included an agreement to pay a
penalty of $500,000 per jurisdiction. PSI consented to a censure and to the
payment of a $5,000,000 fine in settling the NASD action.
 
  In October 1994, a criminal complaint was filed with the United States
Magistrate for the Southern District of New York alleging that PSI committed
fraud in connection with the sale of certain limited partnership interests in
violation of federal securities laws. An agreement was simultaneously filed to
defer prosecution of these charges for a period of three years from the
signing of the agreement, provided that PSI complies with the terms of the
agreement. If, upon completion of the three-year period, PSI has complied with
the terms of the agreement, no prosecution will be instituted by the United
States for the offenses charged in the complaint. If, on the other hand,
during the course of the three-year period, PSI violates the terms of the
agreement, the U.S. Attorney can then elect to pursue these charges. Under the
terms of the agreement, PSI
 
                                      18
<PAGE>
 
agreed, among other things, to pay an additional $330,000,000 into the fund
established by the SEC to pay restitution to investors who purchased certain
PSI limited partnership interests.
   
  For more detailed information concerning the foregoing matters, see
"Distributor" in the Statement of Additional Information, a copy of which may
be obtained at no cost by calling (800) 225-1852.     
 
  The Fund is not affected by PSI's financial condition and is an entirely
separate legal entity from PSI, which has no beneficial ownership therein and
the Fund's assets which are held by State Street Bank and Trust Company, an
independent custodian, are separate and distinct from PSI.
 
PORTFOLIO TRANSACTIONS
 
  Prudential Securities may also act as a broker or futures commission
merchant for the Fund, 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 DIVIDEND DISBURSING AGENT
 
  State Street Bank and Trust Company, One Heritage Drive, North Quincy,
Massachusetts, 02171, serves as Custodian for the Fund's 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), Raritan Plaza One, Edison, New
Jersey 08837, serves as Transfer Agent and Dividend Disbursing Agent and, in
those capacities, maintains certain books and records for the Fund. PMFS is a
wholly-owned subsidiary of PIFM. Its mailing address is P.O. Box 15005, New
Brunswick, New Jersey 08906-5005.     
 
 
                        HOW THE FUND VALUES ITS SHARES
 
 
  THE FUND'S 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. NAV IS CALCULATED SEPARATELY FOR EACH CLASS. For
valuation purposes, quotations of foreign securities in a foreign currency are
converted to U.S. dollar equivalents. THE BOARD OF DIRECTORS HAS FIXED THE
SPECIFIC TIME OF DAY FOR THE COMPUTATION OF THE FUND'S NET ASSET VALUE TO BE
AS OF 4:15 P.M., NEW YORK TIME.
 
  Portfolio securities are valued based on market quotations or, if not
readily available, at fair value as determined in good faith under procedures
established by the Fund's Board of Directors. See "Net Asset Value" in the
Statement of Additional Information.
   
  The Fund will compute its NAV once daily on days that the New York Stock
Exchange is open for trading except on days on which no orders to purchase,
sell or redeem shares have been received by the Fund or days on which changes
in the value of the Fund's portfolio securities do not materially affect the
NAV.     
   
  Although the legal rights of each class of shares are substantially
identical, the different expenses borne by each class will result in different
NAVs and dividends. The NAV of Class B and Class C shares will generally be
lower than the NAV of Class A shares as a result of the larger distribution-
related fee to which Class B and Class C shares are subject. The NAV of Class
Z shares will generally be higher than the NAV of the other three classes
because Class Z shares are not subject to any distribution and/or service
fees. It is expected, however, that the NAV of the four classes will tend to
converge immediately after the recording of dividends, if any, which will
differ by approximately the amount of the distribution and/or service fee
expense accrual differential among the classes.

                      HOW THE FUND CALCULATES PERFORMANCE
   
  FROM TIME TO TIME THE FUND MAY ADVERTISE ITS TOTAL RETURN (INCLUDING
"AVERAGE ANNUAL" TOTAL RETURN AND "AGGREGATE" TOTAL RETURN) AND YIELD IN
ADVERTISEMENTS OR SALES LITERATURE. TOTAL RETURN AND YIELD ARE CALCULATED
SEPARATELY FOR CLASS A, CLASS B, CLASS C AND CLASS Z SHARES. These figures are
based on historical earnings and are not intended to indicate future
performance. The "total return" shows how much an investment in the Fund would
have increased (decreased) over a specified period of time (i.e., one, five or
ten years or since inception of the Fund) assuming that all distributions and
dividends by the Fund were reinvested on the reinvestment dates during the
period and less all recurring fees. The "aggregate" total return reflects
actual performance over a stated period of time. "Average annual" total return
is a hypothetical rate of return that, if achieved annually, would have
produced the same aggregate total return if performance had been constant over
the entire period. "Average annual" total return smooths out variations in
performance and takes into account any applicable initial or contingent
deferred sales charges. Neither "average annual" total return nor "aggregate"
total return takes into account any federal or state income taxes which may be
payable upon redemption. The "yield" refers to the income generated by an
investment in the Fund over a one-month or 30-day period. This income is then
"annualized;" that is, the amount of income generated by the investment during
that 30-day period is assumed to be generated each 30-day period for twelve
periods and is shown as a percentage of the investment. The income earned on
the investment is also assumed to be reinvested at the end of the sixth 30-day
period. The Fund also may include comparative performance information in
advertising or marketing the Fund's shares. Such performance information may
include data from Lipper Analytical Services, Inc., Morningstar Publications,
Inc., other industry publications, business periodicals and market indices.
See "Performance Information" in the Statement of Additional Information.
Further performance information is contained in the Fund's annual and semi-
annual reports to shareholders, which may be obtained without charge. See
"Shareholder Guide--Shareholder Services--Reports to Shareholders."     
 
 
                      TAXES, DIVIDENDS AND DISTRIBUTIONS
 
 
TAXATION OF THE FUND
   
  THE FUND HAS ELECTED TO QUALIFY AND INTENDS TO REMAIN QUALIFIED AS A
REGULATED INVESTMENT COMPANY UNDER THE INTERNAL REVENUE CODE. ACCORDINGLY, THE
FUND WILL NOT BE SUBJECT TO FEDERAL INCOME TAXES ON ITS NET INVESTMENT INCOME
AND CAPITAL GAINS, IF ANY, THAT IT DISTRIBUTES TO ITS SHAREHOLDERS. See
"Taxes, Dividends and Distributions" in the Statement of Additional
Information.     
   
  Under the Internal Revenue Code, special rules apply to the treatment of
certain options and futures contracts (Section 1256 contracts). At the end of
each year, such investments held by the Fund will be required to be "marked to
market" for federal income tax purposes; that is, treated as having been sold
at market value. Sixty percent of any gain or loss recognized on these "deemed
sales" and on actual dispositions will be treated as long-term capital gain or
loss, and the remainder will be treated as short-term capital gain or loss.
See "Taxes, Dividends and Distributions" in the Statement of Additional
Information.     
   
  The Fund may incur foreign income taxes in connection with some of its
foreign investments. Certain of these taxes may be credited to shareholders.
See "Taxes, Dividends and Distributions" in the Statement of Additional
Information. The Fund may, from time to time, invest in Passive Foreign
Investment Companies (PFICs). PFICs are foreign corporations which own mostly
passive assets or which derive 75% or more of their income from passive
sources. The Fund's investments in PFICs may subject the Fund to federal
income tax on certain income and gains realized by the Fund.     
 
                                      20
<PAGE>
 
   
  Certain gains or losses from fluctuations in foreign currency exchange rates
(Section 988 gains or losses) will affect the amount of ordinary income the
Fund will be able to pay as dividends. See "Taxes, Dividends and Distribution"
in the Statement of Additional Information.     
 
TAXATION OF SHAREHOLDERS
   
  Any 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) distributed to shareholders, will be taxable as
ordinary income to the shareholder whether or not reinvested. Any net capital
gains ( i.e., the excess of net long-term capital gains over net short-term
capital losses) distributed to shareholders will be taxable as long-term
capital gains to the shareholders, whether or not reinvested and regardless of
the length of time a shareholder has owned his or her shares. The maximum
long-term capital gains rate for individuals is 28%. The maximum long-term
capital gains rate for corporate shareholders is currently the same as the
maximum tax rate for ordinary income.     
   
  Dividends received by corporate shareholders are eligible for a dividends
received deduction of 70% to the extent the Fund's income is derived from
qualified dividends received by the Fund from domestic corporations. See
"Taxes, Dividends and Distributions" in the Statement of Additional
Information. Corporate shareholders should consult their tax advisers
regarding other requirements applicable to the dividends received deduction.
    
  Any gain or loss realized upon a sale or redemption of shares of the Fund by
a shareholder who is not a dealer in securities will generally 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 with respect
to shares that are held for six months or less, however, will be treated as
long-term capital loss to the extent of any capital gain distributions
received by the shareholder.
   
  The Fund has obtained opinions of counsel to the effect that neither (i) the
conversion of Class B shares into Class A shares nor (ii) the exchange of any
class of the Fund's shares for any other class of its shares constitutes a
taxable event for federal income tax purposes. However, such opinions are not
binding on the Internal Revenue Service.     
       
WITHHOLDING TAXES
 
  Under the Internal Revenue Code, the Fund is required to withhold and remit
to the U.S. Treasury 31% of dividend, 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. Withholding at this
rate is also required from dividends and capital gains distributions (but not
redemption proceeds) payable to shareholders who are otherwise subject to
backup withholding. Dividends of net investment income and 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
   
  THE FUND EXPECTS TO PAY DIVIDENDS OF NET INVESTMENT INCOME, IF ANY, AND MAKE
DISTRIBUTIONS AT LEAST ANNUALLY OF ANY CAPITAL GAINS IN EXCESS OF NET LONG-
TERM CAPITAL LOSSES. Dividends paid by the Fund with respect to each class of
shares, to the extent any dividends are paid, will be calculated in the same
manner, at the same time, on the same day and will be in the same amount
except that each class (other than Class Z) will bear its own distribution
charges, generally resulting in lower dividends for Class B and Class C shares
in relation to Class A and Class Z shares and lower dividends for Class A
shares in relation to Class Z shares. Distributions of net capital gains, if
any, will be paid in the same amount for each class of shares. See "How the
Fund Values its Shares."     
 
                                      21
<PAGE>
 
   
  DIVIDENDS AND DISTRIBUTIONS WILL BE PAID IN ADDITIONAL FUND SHARES BASED ON
THE NAV OF EACH CLASS ON THE RECORD DATE OR SUCH OTHER DATE AS THE BOARD OF
DIRECTORS MAY DETERMINE, UNLESS THE SHAREHOLDER ELECTS IN WRITING NOT LESS
THAN FIVE BUSINESS DAYS PRIOR TO THE RECORD DATE TO RECEIVE SUCH DIVIDENDS AND
DISTRIBUTIONS IN CASH. Such election should be submitted to Prudential Mutual
Fund Services LLC, Attention: Account Maintenance, P.O. Box 15015, New
Brunswick, New Jersey 08906-5015. If you hold shares through Prudential
Securities, you should contact your financial adviser to elect to receive
dividends and distributions in cash. The Fund will notify each shareholder
after the close of the Fund's taxable year both of the dollar amount and the
taxable status of that year's dividends and distributions on a per share
basis.     
   
  WHEN THE FUND GOES "EX-DIVIDEND," THE NAV OF EACH CLASS IS REDUCED BY THE
AMOUNT OF THE DIVIDEND OR DISTRIBUTION ALLOCABLE TO EACH CLASS. IF YOU BUY
SHARES JUST PRIOR TO THE EX-DIVIDEND DATE (WHICH GENERALLY OCCURS TWO BUSINESS
DAYS PRIOR TO THE RECORD DATE), THE PRICE YOU PAY WILL INCLUDE THE DIVIDEND OR
DISTRIBUTION AND A PORTION OF YOUR INVESTMENT WILL BE RETURNED TO YOU AS A
TAXABLE DIVIDEND OR DISTRIBUTION. YOU SHOULD, THEREFORE, CONSIDER THE TIMING
OF DIVIDENDS AND DISTRIBUTIONS WHEN MAKING YOUR PURCHASES.     
 
 
                              GENERAL INFORMATION
 
 
DESCRIPTION OF COMMON STOCK
   
  THE FUND WAS INCORPORATED IN MARYLAND ON JUNE 15, 1987. THE FUND IS
AUTHORIZED TO ISSUE 500 MILLION SHARES OF COMMON STOCK, $.01 PAR VALUE PER
SHARE, DIVIDED INTO FOUR CLASSES, DESIGNATED CLASS A, CLASS B, CLASS C AND
CLASS Z COMMON STOCK, EACH OF WHICH CONSISTS OF 125 MILLION AUTHORIZED SHARES.
Each class of common stock represents an interest in the same assets of the
Fund and is identical in all respects except that (i) each class is subject to
different sales charges and distribution and/or service fees (except for Class
Z shares, which are not subject to any sales charges or distribution and/or
service fees), which may affect performance, (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, (iii) each class has a different exchange privilege, (iv)
only Class B shares have a conversion feature and (v) Class Z shares are
offered exclusively for sale to a limited group of investors. See "How the
Fund is Managed--Distributor." In accordance with the Fund's Articles of
Incorporation, the Board of Directors may authorize the creation of additional
series of common stock and classes within such series, with such preferences,
privileges, limitations and voting and dividend rights as the Board of
Directors may determine.     
   
  The Board of Directors may increase or decrease the number of authorized
shares without approval by the shareholders. Shares of the Fund, 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 Fund under
certain circumstances as described under "Shareholder Guide--How to Sell Your
Shares." Each share of each class of common stock is equal as to earnings,
assets and voting privileges, except as noted above, and each class (with the
exception of Class Z shares, which are not subject to any distribution or
service fee) bears the expenses related to the distribution of its shares.
Except for the conversion feature applicable to the Class B shares, there are
no conversion, preemptive or other subscription rights. In the event of
liquidation, each share of common stock of the Fund is entitled to its portion
of all of the Fund's assets after all debt and expenses of the Fund have been
paid. Since Class B and Class C shares generally bear higher distribution
expenses than Class A shares, the liquidation proceeds to shareholders of
those classes are likely to be lower than to Class A shareholders and to Class
Z shareholders, whose shares are not subject to any distribution and/or
service fees. The Fund's shares do not have cumulative voting rights for the
election of Directors.     
 
  THE FUND DOES NOT INTEND TO HOLD ANNUAL MEETINGS OF SHAREHOLDERS UNLESS
OTHERWISE REQUIRED BY LAW. THE FUND WILL NOT BE REQUIRED TO HOLD MEETINGS OF
SHAREHOLDERS UNLESS, FOR EXAMPLE, THE ELECTION OF DIRECTORS IS REQUIRED TO
 
                                      22
<PAGE>
 
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.

</TABLE>    
   
  The four classes of shares represent an interest in the same portfolio of
investments of the Fund and have the same rights, except that (i) each class
(with the exception of the Class Z shares, which are not subject to any
distribution or service fees) is subject to different sales charges and
distribution and/or service fees, which may affect performance, (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
interest of any other class, and (iii) only Class B shares have a conversion
feature. The four classes also have separate exchange privileges. See "How to
Exchange Your Shares" below. The income attributable to each class and the
dividends payable on the shares of each class will be reduced by the amount of
the distribution fee (if any) of each class. Class B and Class C shares bear
the expenses of a higher distribution fee which will generally cause them to
have higher expense ratios and to pay lower dividends than the Class A and
Class Z shares.     
   
  Financial advisers and other sales agents who sell shares of the Fund will
receive different compensation for selling Class A, Class B, Class C and Class
Z shares and will generally receive more compensation initially for selling
Class A and Class B shares than for selling Class C or Class Z shares.

  IN SELECTING A PURCHASE ALTERNATIVE, YOU SHOULD CONSIDER, AMONG OTHER
THINGS, (1) the length of time you expect to hold your investment, (2) the
amount of any applicable sales charge (whether imposed at the time of purchase
or redemption) and distribution-related fees, as noted above, (3) whether you
qualify for any reduction or waiver of any applicable sales charge, (4) the
various exchange privileges among the different classes of shares (see "How to
Exchange Your Shares" below) and (5) the fact that Class B shares
automatically convert to Class A shares approximately seven years after
purchase (see "Conversion Feature--Class B Shares" below).
 
  The following is provided to assist you in determining which method of
purchase best suits your individual circumstances and is based on current fees
and expenses being charged to the Fund:
 
  If you intend to hold your investment in the Fund for less than 7 years and
do not qualify for a reduced sales charge on Class A shares, since Class A
shares are subject to a maximum initial sales charge of 5% and Class B shares
are subject to a CDSC of 5% which declines to zero over a 6 year period, you
should consider purchasing Class C shares over either Class A or Class B
shares.
 
  If you intend to hold your investment for 7 years or more and do not qualify
for a reduced sales charge on Class A shares, since Class B shares convert to
Class A shares approximately 7 years after purchase and because all of your
money would be invested initially in the case of Class B shares, you should
consider purchasing Class B shares over either Class A or Class C shares.
 
  If you qualify for a reduced sales charge on Class A shares, it may be more
advantageous for you to purchase Class A shares over either Class B or Class C
shares regardless of how long you intend to hold your investment. However,
unlike Class B and Class C shares, you would not have all of your money
invested initially because the sales charge on Class A shares is deducted at
the time of purchase.
 
  If you do not qualify for a reduced sales charge on Class A shares and you
purchase Class B or Class C shares, you would have to hold your investment for
more than 6 years in the case of Class B shares and Class C shares for the
higher cumulative annual distribution-related fee on those shares to exceed
the initial sales charge plus cumulative annual distribution-related fees on
Class A shares. This does not take into account the time value of money, which
further reduces the impact of the higher Class B or Class C distribution-
related fee on the investment, fluctuations in net asset value, the effect of
the return on the investment over this period of time or redemptions when the
CDSC is applicable.
   
  ALL PURCHASES OF $1 MILLION OR MORE, EITHER AS PART OF A SINGLE INVESTMENT
OR UNDER RIGHTS OF ACCUMULATION OR LETTERS OF INTENT, MUST BE FOR CLASS A
SHARES UNLESS THE PURCHASER IS ELIGIBLE TO PURCHASE CLASS Z SHARES. See
"Reduction and Waiver of Initial Sales Charges" and "Class Z Shares" below.
    
  CLASS A SHARES
 
  The offering price of Class A shares for investors choosing the initial
sales charge alternative is the next determined NAV plus a sales charge
(expressed as a percentage of the offering price and of the amount invested)
as shown in the following table:

  The Distributor may reallow the entire sales charge to dealers. Selling
dealers may be deemed to be underwriters, as that term is defined in the
Securities Act.     
   
  In connection with the sale of Class A shares at NAV (without payment of an
initial sales charge), the Manager, the Distributor or one of their affiliates
will 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.     
 
  REDUCTION AND WAIVER OF INITIAL SALES CHARGES. Reduced sales charges are
available through Rights of Accumulation and Letters of Intent. Shares of the
Fund and shares of other Prudential Mutual Funds (excluding money market funds
other than those acquired pursuant to the exchange privilege) may be
aggregated to determine the applicable reduction. See "Purchase and Redemption
of Fund Shares--Reduction and Waiver of Initial Sales Charges--Class A Shares"
in the Statement of Additional Information.
          
  Benefit Plans. Class A shares may be purchased at NAV, without payment of an
initial sales charge, by pension, profit-sharing or other employee benefit
plans qualified under Section 401 of the Internal Revenue Code and deferred
compensation and annuity plans under Sections 457 and 403(b)(7) of the
Internal Revenue Code (collectively, Benefit Plans), provided that the Benefit
Plan has existing assets of at least $1 million invested in shares of
Prudential Mutual Funds (excluding money market funds other than those
acquired pursuant to the exchange privilege) or 250 eligible employees or
participants. In the case of Benefit Plans whose accounts are held directly
with the Transfer Agent or Prudential Securities and for which the Transfer
Agent or Prudential Securities does individual account recordkeeping (Direct
Account Benefit Plans) and Benefit Plans sponsored by PSI or its subsidiaries
(PSI or Subsidiary Prototype Benefit Plans), Class A shares may be purchased
at NAV by participants who are repaying loans made from such plans to the
participant.     
   
  Prudential Retirement Programs. Class A shares may be purchased at NAV by
certain savings, retirement and deferred compensation plans, qualified or non-
qualified under the Internal Revenue Code, for which Prudential serves as the
plan administrator or recordkeeper, provided that (i) the plan has at least $1
million in existing assets or 250 eligible employees and (ii) the Fund is an
available investment option. These plans include pension, profit-sharing,
stock-bonus or other employee benefit plans under Section 401 of the Internal
Revenue Code, deferred compensation and annuity plans under Sections 457 or
403(b)(7) of the Internal Revenue Code and plans that participate in the
Transfer Agent's PruArray and SmartPath Programs (benefit plan recordkeeping
services) (hereafter referred to as a PruArray or SmartPath Plan). All plans
of a company for which Prudential serves as plan administrator or recordkeeper
are aggregated in meeting the $1 million threshold. The term "existing assets"
as used herein includes stock issued by a plan sponsor, shares of Prudential
Mutual Funds and shares of certain unaffiliated mutual funds that participate
in the PruArray or SmartPath Program (Participating Funds). "Existing assets"
also include monies invested in The Guaranteed Interest Account (GIA), a group
annuity insurance product issued by Prudential, and units of The Stable Value
Fund (SVF), an unaffiliated bank collective fund. Class A shares may also be
purchased at NAV by plans that have monies invested in GIA and SVF, provided
(i) the purchase is made with the proceeds of a redemption from either GIA or
SVF and (ii) Class A shares are an investment option of the plan.     
          
  PruArray Association Benefit Plans. Class A shares are also offered at net
asset value to Benefit Plans or non-qualified plans sponsored by employers
which are members of a common trade, professional or membership association
(Association) that participate in the PruArray Program provided that the
Association enters into a written agreement with Prudential. Such Benefit
Plans or non-qualified plans may purchase Class A shares at net asset value
without regard to the assets or number of participants in the individual
employer's qualified Plan(s) or non-qualified plans so long as the employers
in the Association (i) have retirement plan assets in the aggregate of at
least $1 million or 250 participants in the aggregate and (ii) maintain their
accounts with the Fund's transfer agent.     
 
                                      26
<PAGE>
 
   
  PruArray Savings Program. Class A shares are also offered at net asset value
to employees of companies that enter into a written agreement with Prudential
Retirement Services to participate in the PruArray Savings Program. Under this
Program, a limited number of Prudential Mutual Funds are available for
purchase at net asset value by Individual Retirement Accounts and Savings
Accumulation Plans of the company's employees. The Program is available only
to (i) employees who open an IRA or Savings Accumulation Plan account with the
Transfer Agent and (ii) spouses of employees who open an IRA account with the
Transfer Agent. The program is offered to companies that have at least 250
eligible employees.     
       
          
  Special Rules Applicable to Retirement Plans. After a Benefit Plan or
PruArray Plan qualifies to purchase Class A shares at NAV, all subsequent
purchases will be made at NAV.     
   
  Other Waivers. In addition, Class A shares may be purchased at NAV, through
Prudential Securities or the Transfer Agent, by the following persons: (a)
officers of the Prudential Mutual Funds (including the Fund), (b) employees of
Prudential Securities and PIFM and their subsidiaries and members of the
families of such persons who maintain an "employee related" account at
Prudential Securities or the Transfer Agent, (c) employees of subadvisers of
the Prudential Mutual Funds provided that such purchases at NAV are permitted
by such person's employer (d) Prudential, employees and special agents of
Prudential and its subsidiaries and all persons who have retired directly from
active service with Prudential or one of its subsidiaries, (e) registered
representatives and employees of dealers who have entered into a selected
dealer agreement with Prudential Securities provided that purchases at NAV are
permitted by such person's employer, (f) investors who have a business
relationship with a financial adviser who joined Prudential Securities from
another investment firm, provided that (i) the purchase is made within 180
days of the commencement of the financial adviser's employment at Prudential
Securities, or within one year in the case of Benefit Plans, (ii) the purchase
is made with proceeds of a redemption of shares of any open-end, non-money
market fund sponsored by the financial adviser's previous employer (other than
a fund which imposes a distribution or service fee of .25 of 1% or less) and
(iii) the financial adviser served as the client's broker on the previous
purchase and (g) investors in Individual Retirement Accounts, provided the
purchase is made with the proceeds of a tax-free rollover of assets from a
Benefit Plan for which Prudential Investments serves as the recordkeeper.     
 
  You must notify the Transfer Agent either directly or through Prudential
Securities or Prusec that you are entitled to the reduction or waiver of the
sales charge. The reduction or waiver will be granted subject to confirmation
of your entitlement. No initial sales charges are imposed upon Class A shares
acquired upon the reinvestment of dividends and distributions. See "Purchase
and Redemption of Fund Shares--Reduction and Waiver of Initial Sales Charges--
Class A Shares" in the Statement of Additional Information.
 
CLASS B AND CLASS C SHARES
   
  The offering price of Class B and Class C shares for investors choosing one
of the deferred sales charge alternatives is the NAV next determined following
receipt of an order by the Transfer Agent or Prudential Securities. Although
there is no sales charge imposed at the time of purchase, redemptions of Class
B and Class C shares may be subject to a CDSC. See "How to Sell Your Shares--
Contingent Deferred Sales Charges." The Distributor will pay sales commissions
of up to 4% of the purchase price of Class B shares to dealers, financial
advisers and other persons who sell Class B shares at the time of sale from
its own resources. This facilitates the ability of the Fund to sell the Class
B shares without an initial sales charge being deducted at the time of
purchase. The Distributor anticipates that it will recoup its advancement of
sales commissions from the combination of the CDSC and the distribution fee.
See "How the Fund is Managed--Distributor." In connection with the sale of
Class C shares, the Distributor will pay dealers, financial advisers and other
persons which distribute Class C shares a sales commission of up to 1% of the
purchase price of such shares at the time of the sale.

CLASS Z SHARES     
   
  Class Z shares of the Fund are available for purchase by the following
categories of investors:     
   
  (i) pension, profit-sharing or other employee benefit plans qualified under
Section 401 of the Internal Revenue Code, deferred compensation and annuity
plans under Sections 457 or 403(b)(7) of the Internal Revenue Code and non-
qualified plans for which the Fund is an available option (collectively,
Benefit Plans), provided such Benefit Plans (in combination with other plans
sponsored by the same employer or group of related employers) have at least
$50 million in defined contribution assets; (ii) participants in any fee-based
program or trust program sponsored by Prudential Securities, The Prudential
Savings Bank, F.S.B. (or any affiliate) which includes mutual funds as
investment options and for which the Fund is an available option; (iii)
certain participants in the MEDLEY Program (group variable annuity contracts)
sponsored by Prudential for whom Class Z shares of the Prudential Mutual Funds
are an available investment option; (iv) Benefit Plans for which Prudential
Retirement Services serves as recordkeeper and as of September 20, 1996, (a)
were Class Z shareholders of the Prudential Mutual Funds, or (b) executed a
letter of intent to purchase Class Z shares of the Prudential Mutual Funds;
(v) current and former Directors/Trustees of the Prudential Mutual Funds
(including the Fund); and (vi) employees of Prudential and/or Prudential
Securities who participate in a Prudential-sponsored employee savings plan.
       
  In connection with the sales of Class Z 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.     
 
HOW TO SELL SHARES
       
  YOU CAN REDEEM YOUR SHARES AT ANY TIME FOR CASH AT THE NAV NEXT DETERMINED
AFTER THE REDEMPTION REQUEST IS RECEIVED IN PROPER FORM BY THE TRANSFER AGENT
OR PRUDENTIAL SECURITIES. SEE "HOW THE FUND VALUES ITS SHARES." In certain
cases, however, redemption proceeds will be reduced by the amount of any
applicable contingent deferred sales charge, as described below. See
"Contingent Deferred Sales Charges" below.
   
  IF YOU HOLD SHARES OF THE FUND THROUGH PRUDENTIAL SECURITIES, YOU MUST
REDEEM YOUR SHARES THROUGH PRUDENTIAL SECURITIES. PLEASE CONTACT YOUR
PRUDENTIAL SECURITIES FINANCIAL ADVISER.     
   
  IF YOU HOLD SHARES IN NON-CERTIFICATE FORM, A WRITTEN REQUEST FOR REDEMPTION
SIGNED BY YOU EXACTLY AS THE ACCOUNT IS REGISTERED IS REQUIRED. IF YOU HOLD
CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON THE FACE OF THE
CERTIFICATES, MUST BE RECEIVED BY THE TRANSFER AGENT IN ORDER FOR THE
REDEMPTION REQUEST TO BE PROCESSED. IF REDEMPTION IS REQUESTED BY A
CORPORATION, PARTNERSHIP, TRUST OR FIDUCIARY, WRITTEN EVIDENCE OF AUTHORITY
ACCEPTABLE TO THE TRANSFER AGENT MUST BE SUBMITTED BEFORE SUCH REQUEST WILL BE
ACCEPTED. All correspondence and documents concerning redemptions should be
sent to the Fund in care of its Transfer Agent, Prudential Mutual Fund
Services LLC, Attention: Redemption Services, P.O. Box 15010, New Brunswick,
New Jersey 08906-5010.     
   
  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." 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 or Preferred
Services offices. In the case of redemptions from a PruArray or SmartPath
Plan, if the proceeds of the redemption are invested in another investment
option of the plan, in the name of the record holder and at the same address
as reflected in the Transfer Agent's records, a signature guarantee is not
required.     
 
 
                                      28
<PAGE>
 
  PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE MADE BY CHECK WITHIN
SEVEN DAYS AFTER RECEIPT BY THE TRANSFER AGENT OF THE CERTIFICATE AND/OR
WRITTEN REQUEST, EXCEPT AS INDICATED BELOW. IF YOU HOLD SHARES THROUGH
PRUDENTIAL SECURITIES, PAYMENT FOR SHARES PRESENTED FOR REDEMPTION WILL BE
CREDITED TO YOUR PRUDENTIAL SECURITIES ACCOUNT UNLESS YOU INDICATE OTHERWISE.
Such payment may be postponed or the right of redemption suspended at times
(a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on such Exchange is restricted, (c)
when an emergency exists as a result of which disposal by the Fund of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for the Fund fairly to determine the value of its net assets, or
(d) during any other period when the SEC, by order, so permits; provided that
applicable rules and regulations of the SEC shall govern as to whether the
conditions prescribed in (b), (c) or (d) exist.
   
  PAYMENT FOR REDEMPTION OF RECENTLY PURCHASED SHARES WILL BE DELAYED UNTIL
THE FUND OR ITS TRANSFER AGENT HAS BEEN ADVISED THAT THE PURCHASE CHECK HAS
BEEN HONORED, UP TO 10 CALENDAR DAYS FROM THE TIME OF RECEIPT OF THE PURCHASE
CHECK BY THE TRANSFER AGENT. SUCH DELAY MAY BE AVOIDED BY PURCHASING SHARES BY
WIRE OR BY CERTIFIED OR CASHIER'S CHECK.     
 
  REDEMPTION IN KIND. If the Board of Directors determines that it would be
detrimental to the best interests of the remaining shareholders of the Fund to
make payment wholly or partly in cash, the Fund may pay the redemption price
in whole or in part by a distribution in kind of securities from the
investment portfolio of the Fund, 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 a regular redemption. See "How the Fund Values
its Shares." If your shares are redeemed in kind, you will incur transaction
costs in converting the assets into cash. The Fund, however, has elected to be
governed by Rule 18f-1 under the Investment Company Act, under which the Fund
is obligated to redeem shares solely in cash up to the lesser of $250,000 or
1% of the net asset value of the Fund during any 90-day period for any one
shareholder.
 
  INVOLUNTARY REDEMPTION. In order to reduce expenses of the Fund, the Board
of Directors may redeem all of the shares of any shareholder, other than a
shareholder which is an IRA or other tax-deferred retirement plan, whose
account has a net asset value of less than $500 due to a redemption. The Fund
will give such shareholders 60 days' prior written notice in which to purchase
sufficient additional shares to avoid such redemption. No contingent deferred
sales charge will be imposed on any such involuntary redemption.
   
  90-DAY REPURCHASE PRIVILEGE. If you redeem your shares and have not
previously exercised the repurchase privilege, you may reinvest any portion or
all of the proceeds of such redemption in shares of the Fund at the NAV next
determined after the order is received, which must be within 90 days after the
date of the redemption. Any CDSC paid in connection with such redemption will
be credited (in shares) to your account. (If less than a full repurchase is
made, the credit will be on a pro rata basis.) You must notify the Fund's
Transfer Agent, either directly or through Prudential Securities, at the time
the repurchase privilege is exercised to adjust your account for the CDSC you
previously paid. Thereafter, any redemptions will be subject to the CDSC
applicable at the time of the redemption. See "Contingent Deferred Sales
Charges" below. Exercise of the repurchase privilege will generally not affect
the federal tax treatment of any gain or loss realized upon redemption.
However, if the redemption was made within a 30 day period of the repurchase
and if the redemption resulted in a loss, some or all of the loss, depending
on the amount reinvested, may not be allowed for federal income tax purposes.
See "Taxes, Dividends and Distributions" in the Statement of Additional
Information.     
 
  CONTINGENT DEFERRED SALES CHARGES
 
  Redemptions of Class B shares will be subject to a contingent deferred sales
charge or CDSC declining from 5% to zero over a six-year period. Class C
shares redeemed within one year of purchase will be subject to a 1% CDSC. The
CDSC will be deducted from the redemption proceeds and reduce the amount paid
to you. The CDSC will be imposed on any redemption by you which reduces the
current value of your Class B or Class C shares to an amount which is lower
than the amount of all payments by you for shares during the preceding six
years, in the case of Class B shares, and one
 
                                      29
<PAGE>
 
year, in the case of Class C shares. A CDSC will be applied on the lesser of
the original purchase price or the current value of the shares being redeemed.
Increases in the value of your shares or shares acquired through reinvestment
of dividends or distributions are not subject to a CDSC. The amount of any
contingent deferred sales charge will be paid to and retained by the
Distributor. See "How the Fund is Managed--Distributor" and "Waiver of the
Contingent Deferred Sales Charges--Class B Shares" below.
   
  The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of shares until the time of
redemption of such shares. Solely for purposes of determining the number of
years from the time of any payment for the purchase of shares, all payments
during a month will be aggregated and deemed to have been made on the last day
of the month. The CDSC will be calculated from the first day of the month
after the initial purchase, excluding the time shares were held in a money
market fund. See "How to Exchange Your Shares" below.     
 
  The following table sets forth the rates of the CDSC applicable to
redemptions of Class B shares:

</TABLE>
 
  In determining whether a CDSC is applicable to a redemption, the calculation
will be made in a manner that results in the lowest possible rate. It will be
assumed that the redemption is made first of amounts representing shares
acquired pursuant to the reinvestment of dividends and distributions; then of
amounts representing the increase in net asset value above the total amount of
payments for the purchase of Fund shares made during the preceding six years
(five years for Class B shares purchased prior to January 22, 1990); then of
amounts representing the cost of shares held beyond the applicable CDSC
period; and finally, of amounts representing the cost of shares held for the
longest period of time within the applicable CDSC period.
 
  For example, assume you purchased 100 Class B shares at $10 per share for a
cost of $1,000. Subsequently, you acquired 5 additional Class B shares through
dividend reinvestment. During the second year after the purchase you decided
to redeem $500 of your investment. Assuming at the time of the redemption the
NAV had appreciated to $12 per share, the value of your Class B shares would
be $1,260 (105 shares at $12 per share). The CDSC would not be applied to the
value of the reinvested dividend shares and the amount which represents
appreciation ($260). Therefore, $240 of the $500 redemption proceeds ($500
minus $260) would be charged at a rate of 4% (the applicable rate in the
second year after purchase) for a total CDSC of $9.60.
 
  For federal income tax purposes, the amount of the CDSC will reduce the gain
or increase the loss, as the case may be, on the amount recognized on the
redemption of shares.
 
  WAIVER OF THE CONTINGENT DEFERRED SALES CHARGES--CLASS B SHARES. The CDSC
will be waived in the case of a redemption following the death or disability
of a shareholder or, in the case of a trust account, following the death or
disability of the grantor. The waiver is available for total or partial
redemptions of shares owned by a person, either individually or in joint
tenancy (with rights of survivorship), at the time of death or initial
determination of disability, provided that the shares were purchased prior to
death or disability.
 
  The CDSC will also be waived in the case of a total or partial redemption in
connection with certain distributions made without penalty under the Internal
Revenue Code from a tax-deferred retirement plan, an IRA or Section 403(b)
custodial
 
                                      30
<PAGE>
 
account. These distributions include: (i) in the case of a tax-deferred
retirement plan, a lump-sum or other distribution after retirement; (ii) in
the case of an IRA or Section 403(b) custodial account, a lump-sum or other
distribution after attaining age 59 1/2; and (iii) a tax-free return of an
excess contribution plan or plan distributions following the death or
disability of the shareholder, provided that the shares were purchased prior
to death or disability. The waiver does not apply in the case of a tax-free
rollover or transfer of assets, other than one following a separation from
service (i.e., following voluntary or involuntary termination of employment or
following retirement). Under no circumstances will the CDSC be waived on
redemptions resulting from the termination of a tax-deferred retirement plan,
unless such redemptions otherwise qualify for a waiver as described above. In
the case of Direct Account and PSI or Subsidiary Prototype Benefit Plans, the
CDSC will be waived on redemptions which represent borrowings from such plans.
Shares purchased with amounts used to repay a loan from such plans on which a
CDSC was not previously deducted will thereafter be subject to a CDSC without
regard to the time such amounts were previously invested. In the case of a
401(k) plan, the CDSC will also be waived upon the redemption of shares
purchased with amounts used to repay loans made from the account to the
participant and from which a CDSC was previously deducted.
   
  SYSTEMATIC WITHDRAWAL PLAN. The CDSC will be waived (or reduced) on certain
redemptions from a Systematic Withdrawal Plan. On an annual basis, up to 12%
of the total dollar amount subject to the CDSC may be redeemed without charge.
The Transfer Agent will calculate the total amount available for this waiver
annually on the anniversary date of your purchase or, for shares purchased
prior to March 1, 1997, on March 1 of the current year. The CDSC will be
waived (or reduced) on redemptions until this threshold 12% amount is reached.
    
  In addition, the CDSC will be waived on redemptions of shares held by a
Director of the Fund.
 
  You must notify the Fund's Transfer Agent either directly or through
Prudential Securities or Prusec, at the time of redemption, that you are
entitled to waiver of the CDSC and provide the Transfer Agent with such
supporting documentation as it may deem appropriate. The waiver will be
granted subject to confirmation of your entitlement. See "Purchase and
Redemption of Fund Shares--Waiver of the Contingent Deferred Sales Charge--
Class B Shares" in the Statement of Additional Information.
 
  A quantity discount may apply to redemption of Class B shares purchased
prior to August 1, 1994. See "Purchase and Redemption of Fund Shares--Quantity
Discount--Class B Shares Purchased Prior to August 1, 1994" in the Statement
of Additional Information.
   
WAIVER OF THE CONTINGENT DEFERRED SALES CHARGES--CLASS C SHARES.     
   
  PruArray or SmartPath Plans. The CDSC will be waived on redemptions from
qualified and non-qualified retirement and deferred compensation plans that
participate in the Transfer Agent's PruArray and SmartPath Programs.     
 
CONVERSION FEATURE--CLASS B SHARES
 
  Class B shares will automatically convert to Class A shares on a quarterly
basis approximately seven years after purchase. Conversions will be effected
at relative net asset value without the imposition of any additional sales
charge. The first conversion of Class B shares occurred in February 1995, when
the conversion feature was first implemented.
 
  Since the Fund tracks amounts paid rather than the number of shares bought
on each purchase of Class B shares, the number of Class B shares eligible to
convert to Class A shares (excluding shares acquired through the automatic
reinvestment of dividends and other distributions) (the Eligible Shares) will
be determined on each conversion date in accordance with the following
formula: (i) the ratio of (a) the amounts paid for Class B shares purchased at
least seven years prior to the conversion date to (b) the total amount paid
for all Class B shares purchased and then held in your account (ii) multiplied
by the total number of Class B shares purchased and then held in your account.
Each time any
 
                                      31
<PAGE>
 
Eligible Shares in your account convert to Class A shares, all shares or
amounts representing Class B shares then in your account that were acquired
through the automatic reinvestment of dividends and other distributions will
convert to Class A shares.
 
  For purposes of determining the number of Eligible Shares, if the Class B
shares in your account on any conversion date are the result of multiple
purchases at different net asset values per share, the number of Eligible
Shares calculated as described above will generally be either more or less
than the number of shares actually purchased approximately seven years before
such conversion date. For example, if 100 shares were initially purchased at
$10 per share (for a total of $1,000) and a second purchase of 100 shares was
subsequently made at $11 per share (for a total of $1,100), 95.24 shares would
convert approximately seven years from the initial purchase (i.e., $1,000
divided by $2,100 (47.62%) multiplied by 200 shares equals 95.24 shares). The
Manager reserves the right to modify the formula for determining the number of
Eligible Shares in the future as it deems appropriate on notice to
shareholders.
 
  Since annual distribution-related fees are lower for Class A shares than
Class B shares, the per share net asset value of the Class A shares may be
higher than that of the Class B shares at the time of conversion. Thus,
although the aggregate dollar value will be the same, you may receive fewer
Class A shares than Class B shares converted. See "How the Fund Values its
Shares."
 
  For purposes of calculating the applicable holding period for conversions,
all payments for Class B shares during a month will be deemed to have been
made on the last day of the month, or for Class B shares acquired through
exchange, or a series of exchanges, on the last day of the month in which the
original payment for purchases of such Class B shares was made. For Class B
shares previously exchanged for shares of a money market fund, the time period
during which such shares were held in the money market fund will be excluded.
For example, Class B shares held in a money market fund for one year will not
convert to Class A shares until approximately eight years from purchase. For
purposes of measuring the time period during which shares are held in a money
market fund, exchanges will be deemed to have been made on the last day of the
month. Class B shares acquired through exchange will convert to Class A shares
after expiration of the conversion period applicable to the original purchase
of such shares.
   
  The conversion feature may be subject to the continuing availability of
opinions of counsel or rulings of the Internal Revenue Service (i) that the
dividends and other distributions paid on Class A, Class B, Class C and Class
Z shares will not constitute "preferential dividends" under the Internal
Revenue Code and (ii) that the conversion of shares does not constitute a
taxable event. The conversion of Class B shares into Class A shares may be
suspended if such opinions or rulings are no longer available. If conversions
are suspended, Class B shares of the Fund will continue to be subject,
possibly indefinitely, to their higher annual distribution and service fee.
    
HOW TO EXCHANGE YOUR SHARES
   
  AS A SHAREHOLDER OF THE FUND, YOU HAVE AN EXCHANGE PRIVILEGE WITH CERTAIN
OTHER PRUDENTIAL MUTUAL FUNDS (THE EXCHANGE PRIVILEGE), INCLUDING ONE OR MORE
SPECIFIED MONEY MARKET FUNDS, SUBJECT TO THE MINIMUM INVESTMENT REQUIREMENTS
OF SUCH FUNDS. CLASS A, CLASS B, CLASS C AND CLASS Z SHARES MAY BE EXCHANGED
FOR CLASS A, CLASS B, CLASS C AND CLASS Z SHARES, RESPECTIVELY, OF ANOTHER
FUND ON THE BASIS OF THE RELATIVE NAV. No sales charge will be imposed at the
time of the exchange. Any applicable CDSC payable upon the redemption of
shares exchanged will be calculated from the first day of the month after the
initial purchase excluding the time the shares were held in a money market
fund. Class B and Class C shares may not be exchanged into money market funds
other than Prudential Special Money Market Fund, Inc. For purposes of
calculating the holding period applicable to the Class B conversion feature,
the time period during which Class B shares were held in a money market fund
will be excluded. See "Conversion Feature--Class B Shares" above. An exchange
will be treated as a redemption and purchase for tax purposes. See
"Shareholder Investment Account--Exchange Privilege" in the Statement of
Additional Information.

  IN ORDER TO EXCHANGE SHARES BY TELEPHONE, YOU MUST AUTHORIZE TELEPHONE
EXCHANGES ON YOUR INITIAL APPLICATION FORM AND HOLD SHARES IN NON-CERTIFICATE
FORM. Thereafter, you may call the Fund at (800) 225-1852 to execute a
telephone exchange of shares, on weekdays, except holidays, between the hours
of 8:00 A.M. and 6:00 P.M., New York time. For your protection and to prevent
fraudulent exchanges, your telephone call will be recorded and you will be
asked to provide your personal identification number. A written confirmation
of the exchange transaction will be sent to you. NEITHER THE FUND NOR ITS
AGENTS WILL BE LIABLE FOR ANY LOSS, LIABILITY OR COST WHICH RESULTS FROM
ACTING UPON INSTRUCTIONS REASONABLY BELIEVED TO BE GENUINE UNDER THE FOREGOING
PROCEDURES. All exchanges will be made on the basis of the relative NAV of the
two funds next determined after the request is received in good order. The
Exchange Privilege is available only in states where the exchange may legally
be made.     
 
  IF YOU HOLD SHARES THROUGH PRUDENTIAL SECURITIES, YOU MUST EXCHANGE YOUR
SHARES BY CONTACTING YOUR PRUDENTIAL SECURITIES FINANCIAL ADVISER.
 
  IF YOU HOLD CERTIFICATES, THE CERTIFICATES, SIGNED IN THE NAME(S) SHOWN ON
THE FACE OF THE CERTIFICATES, MUST BE RETURNED IN ORDER FOR THE SHARES TO BE
EXCHANGED. SEE "HOW TO SELL YOUR SHARES" ABOVE.
   
  You may also exchange shares by mail by writing to Prudential Mutual Fund
Services LLC, Attention: Exchange Processing, P.O. Box 15010, New Brunswick,
New Jersey 08906-5010.     
   
  IN PERIODS OF SEVERE MARKET OR ECONOMIC CONDITIONS THE TELEPHONE EXCHANGE OF
SHARES MAY BE DIFFICULT TO IMPLEMENT AND SHAREHOLDERS SHOULD MAKE EXCHANGES BY
MAIL BY WRITING TO PRUDENTIAL MUTUAL FUND SERVICES LLC AT THE ADDRESS NOTED
ABOVE.     
   
  SPECIAL EXCHANGE PRIVILEGES. A special exchange privilege is available for
shareholders who qualify to purchase Class A shares at NAV (see "Alternative
Purchase Plan--Class A Shares--Reduction and Waiver of Initial Sales Charges"
above) and for shareholders who qualify to purchase Class Z shares (see
"Alternative Purchase Plan--Class Z Shares" above). Under this exchange
privilege, amounts representing any Class B and Class C shares (which are not
subject to a CDSC) held in such a shareholder's account will be automatically
exchanged for Class A shares for shareholders who qualify to purchase Class A
shares at NAV on a quarterly basis, unless the shareholder elects otherwise.
Similarly, shareholders who qualify to purchase Class Z shares will have their
Class B and Class C shares which are not subject to a CDSC and their Class A
shares exchanged for Class Z shares on a quarterly basis. Eligibility for this
exchange privilege will be calculated on the business day prior to the date of
the exchange. Amounts representing Class B or Class C shares which are not
subject to a CDSC include the following: (1) amounts representing Class B or
Class C shares acquired pursuant to the automatic reinvestment of dividends
and distributions, (2) amounts representing the increase in the net asset
value above the total amount of payments for the purchase of Class B or Class
C shares and (3) amounts representing Class B or Class C shares held beyond
the applicable CDSC period. Class B and Class C shareholders must notify the
Transfer Agent either directly or through Prudential Securities or Prusec that
they are eligible for this special exchange privilege.     
   
  Participants in any fee-based program for which the Fund is an available
option will have their Class A shares, if any, exchanged for Class Z shares
when they elect to have those assets become a part of the fee-based program.
Upon leaving the program (whether voluntarily or not), such Class Z shares
(and, to the extent provided for in the program, Class Z shares acquired
through participation in the program) will be exchanged for Class A shares at
net asset value.     
   
  The Fund reserves the right to reject any exchange order including exchanges
(and market timing transactions) which are of size and/or frequency engaged in
by one or more accounts acting in concert or otherwise, that have or may have
an adverse effect on the ability of the Subadviser to manage the portfolio.
The determination that such exchanges or activity may have an adverse effect
and the determination to reject any exchange order shall be in the discretion
of the Manager and the Subadviser.     
   
  The Exchange Privilege is not a right and may be suspended, modified or
terminated on 60 days' notice to shareholders.

SHAREHOLDER SERVICES
 
  In addition to the Exchange Privilege, as a shareholder of the Fund, you can
take advantage of the following services and privileges:
 
  . AUTOMATIC REINVESTMENT OF DIVIDENDS AND/OR DISTRIBUTIONS WITHOUT A SALES
CHARGE. For your convenience, all dividends and distributions are
automatically reinvested in full and fractional shares of the Fund at NAV
without a sales charge. You may direct the Transfer Agent in writing not less
than 5 full business days prior to the record date to have subsequent
dividends and/or distributions sent in cash rather than reinvested. If you
hold shares through Prudential Securities, you should contact your financial
adviser.
 
  . AUTOMATIC SAVINGS ACCUMULATION PLAN (ASAP). Under ASAP you may make
regular purchases of the Fund's shares in amounts as little as $50 via an
automatic debit to a bank account or Prudential Securities account (including
a Command Account). For additional information about this service, you may
contact your Prudential Securities financial adviser, Prusec representative or
the Transfer Agent directly.
 
  . TAX-DEFERRED RETIREMENT PLANS. Various tax-deferred retirement plans,
including a 401(k) plan, self-directed individual retirement accounts and
"tax-sheltered accounts" under Section 403(b)(7) of the Internal Revenue Code
are available through the Distributor. These plans are for use by both self-
employed individuals and corporate employers. These plans permit either self-
direction of accounts by participants, or a pooled account arrangement.
Information regarding the establishment of these plans, the administration,
custodial fees and other details is available from Prudential Securities or
the Transfer Agent. If you are considering adopting such a plan, you should
consult with your own legal or tax adviser with respect to the establishment
and maintenance of such a plan.
 
  . SYSTEMATIC WITHDRAWAL PLAN. A systematic withdrawal plan is available to
shareholders which provides for monthly or quarterly checks. Withdrawals of
Class B and Class C shares may be subject to a CDSC. See "How to Sell Your
Shares--Contingent Deferred Sales Charges."
   
  . REPORTS TO SHAREHOLDERS. The Fund will send you annual and semi-annual
reports. The financial statements appearing in 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. In addition,

                      Statement of Additional Information
                              
                           dated July 30, 1997     
   
  Prudential Natural Resources Fund, Inc. (the Fund), is an open-end,
diversified, management investment company. Its investment objective is long-
term growth of capital. It seeks to achieve this objective by investing
primarily in securities of foreign and domestic companies that own, explore,
mine, process or otherwise develop, or provide goods and services with respect
to, natural resources and in securities, the terms of which are related to the
market value of a natural resource (asset-based securities). The Fund will,
under normal circumstances, invest at least 65% of its total assets in common
stocks and equivalents (such as convertible debt securities and warrants) of
natural resource companies and in asset-based securities. The Fund may also
invest in equity securities of companies in other industries, fixed-income
securities (including money market instruments), and derivatives, including
options on equity securities, stock indices, foreign currencies and futures
contracts on foreign currencies, and may buy and sell futures contracts on
foreign currencies and on stock indices so as to hedge its portfolio. There
can be no assurance that the Fund's investment objective will be achieved. See
"Investment Objective and Policies."     
   
  The Fund's address is Gateway Center Three, 100 Mulberry Street, Newark New
Jersey 07102-4077, and its telephone number is (800) 225-1852.     
   
  This Statement of Additional Information is not a prospectus and should be
read in conjunction with the Fund's Prospectus dated July 30, 1997, a copy of
which may be obtained from the Fund upon request.

                              GENERAL INFORMATION
 
  At a special meeting held on July 19, 1994, shareholders approved an
amendment to the Fund's Articles of Incorporation to change the Fund's name
from Prudential-Bache Global Natural Resources Fund, Inc. to Prudential Global
Natural Resources Fund, Inc. Effective July 30, 1996, the Fund's name changed
to Prudential Natural Resources Fund, Inc.
 
                       INVESTMENT OBJECTIVE AND POLICIES
 
  The Fund seeks to achieve its investment objective of long-term growth of
capital by investing primarily in securities of foreign and domestic companies
that own, explore, mine, process or otherwise develop, or provide goods and
services with respect to, natural resources and in asset-based securities.
There can be no assurance that the Fund's investment objective will be
achieved. See "How the Fund Invests--Investment Objective and Policies" in the
Prospectus.
 
OPTIONS TRANSACTIONS
 
  OPTIONS ON EQUITY SECURITIES. The Fund intends to purchase and write (i.e.,
sell) put and call options that are traded on U.S. or foreign securities
exchanges or that are listed on NASDAQ or that are traded over-the-counter. A
call option is a short-term contract (having a duration of nine months or
less) pursuant to which the purchaser, in return for a premium paid, has the
right to buy the security underlying the option at a specified exercise price
at any time during the term of the option. The writer of the call option, who
receives the premium, has the obligation, upon exercise of the option, to
deliver the underlying security against payment of the exercise price. A put
option is a similar contract which gives the purchaser, in return for a
premium, the right to sell the underlying security at a specified price during
the term of the option. The writer of the put, who receives the premium, has
the obligation to buy the underlying security upon exercise at the exercise
price. The Fund will write put options only when the investment adviser
desires to invest in the underlying security.
   
  A call option written by the Fund is "covered" if the Fund owns the security
underlying the option or has an absolute and immediate right to acquire that
security without additional consideration (or for additional consideration
held in a segregated account by its Custodian) upon conversion or exchange of
other securities held in its portfolio. A call option is also "covered" if the
Fund holds on a share-for-share basis a call on the same security as the call
written where the exercise price of the call held is equal to or less than the
exercise price of the call written or greater than the exercise price of the
call written if the difference is maintained by the Fund in cash or other
liquid assets in a segregated account with its Custodian. A put option written
by the Fund is "covered" if the Fund maintains cash, U.S. Government
obligations or other liquid, unencumbered assets, marked to market daily, with
a value equal to the exercise price in a segregated account with its
Custodian, or else holds on a share-for-share basis a put of the same security
as the put written where the exercise price of the put held is equal to or
greater than the exercise price of the put written. The premium paid by the
purchaser of an option will reflect, among other things, the relationship of
the exercise price to the market price and volatility of the underlying
security, the remaining term of the option, supply and demand and interest
rates.     
 
  If the writer of an option wishes to terminate the obligation, he or she may
effect a "closing purchase transaction." This is accomplished by buying an
option of the same series as the option previously written. The effect of the
purchase is that the writer's position will be cancelled by the clearing
corporation. However, a writer may not effect a closing purchase transaction
after he or she has been notified of the exercise of an option. Similarly, an
investor who is the holder of an option may liquidate his or her position by
effecting a "closing sale transaction." This is accomplished by selling an
option of the same series as the option previously purchased. There is no
guarantee that either a closing purchase or a closing sale transaction can be
effected. To secure the obligation to deliver the underlying security in the
case of a call option, the writer of the option is generally required to
pledge for the benefit of the broker the underlying security or other assets
in accordance with the rules of the relevant exchange or clearinghouse, such
as The Options Clearing Corporation (OCC), an institution created to interpose
itself between buyers and sellers of options in the United States.
Technically, the clearinghouse assumes the other side of every purchase and
sale transaction on an exchange and, by doing so, guarantees the transaction.
 
  The Fund will realize a profit from a closing transaction if the price of
the transaction is less than the premium received from writing the option or
is more than the premium paid to purchase the option; the Fund will realize a
loss from a closing transaction if the price of the transaction is more than
the premium received from writing the option or is less than the premium paid
to purchase the option. Because increases in the market price of a call option
will generally reflect increases in the market price of the underlying
security, any loss resulting from the repurchase of a call option is likely to
be offset in whole or in part by appreciation of the underlying security owned
by the Fund.
 
                                      B-2
<PAGE>
 
  The Fund may also purchase a "protective put," i.e., a put option acquired
for the purpose of protecting a portfolio security from a decline in market
value. In exchange for the premium paid for the put option, the Fund acquires
the right to sell the underlying security at the exercise price of the put
regardless of the extent to which the underlying security declines in value.
The loss to the Fund is limited to the premium paid for, and transaction costs
in connection with, the put plus the initial excess, if any, of the market
price of the underlying security over the exercise price. However, if the
market price of the security underlying the put rises, the profit the Fund
realizes on the sale of the security will be reduced by the premium paid for
the put option less any amount (net of transaction costs) for which the put
may be sold. Similar principles apply to the purchase of puts on stock
indices, as described below.
 
  OPTIONS ON STOCK INDICES. In addition to options on equity securities, the
Fund may also purchase and sell put and call options on stock indices traded
on U.S. and foreign securities exchanges or listed on NASDAQ. Options on stock
indices are similar to options on stock except that, rather than the right to
take or make delivery of stock at a specified price, an option on a stock
index gives the holder the right to receive, upon exercise of the option, an
amount of cash if the closing level of the stock index upon which the option
is based is greater than, in the case of a call, or less than, in the case of
a put, the exercise price of the option. This amount of cash is equal to such
difference between the closing price of the index and the exercise price of
the option, expressed in dollars, times a specified multiple (the multiplier).
The writer of the option is obligated, in return for the premium received, to
make delivery of this amount. Unlike stock options, all settlements are in
cash, and gain or loss depends on price movements in the stock market
generally (or in a particular industry or segment of the market) rather than
price movements in individual stocks.
 
  The multiplier for an index option performs a function similar to the unit
of trading for a stock option. It determines the total dollar value per
contract of each point in the difference between the exercise price of an
option and the current level of the underlying index. A multiplier of 100
means that a one-point difference will yield $100. Options on different
indices may have different multipliers.
 
  Because exercises of index options are settled in cash, a call writer cannot
determine the amount of its settlement obligations in advance and, unlike call
writing on specific stocks, cannot provide in advance for, or cover, its
potential settlement obligations by acquiring and holding the underlying
securities. In addition, unless the Fund has other liquid assets which are
sufficient to satisfy the exercise of a call, the Fund would be required to
liquidate portfolio securities or borrow in order to satisfy the exercise.
 
  Because the value of an index option depends upon movements in the level of
the index rather than the price of a particular stock, whether the Fund will
realize a gain or loss on the purchase or sale of an option on an index
depends upon movements in the level of stock prices in the stock market
generally or in an industry or market segment rather than movements in the
price of a particular stock. Accordingly, successful use by the Fund of
options on indices would be subject to the investment adviser's ability to
predict correctly movements in the direction of the stock market generally or
of a particular industry. This requires different skills and techniques than
predicting changes in the price of individual stocks. The investment adviser
currently uses such techniques in conjunction with the management of other
mutual funds.
 
STOCK INDEX FUTURES AND OPTIONS THEREON
   
  The Fund may attempt to reduce the risk of investment in equity securities
by hedging a portion of its portfolio through the use of stock index futures
and options on stock index futures traded on a commodities exchange or board
of trade. A stock index futures contract is an agreement in which the writer
(or seller) of the contract agrees to deliver to the buyer an amount of cash
equal to a specific dollar amount times the difference between the value of a
specific stock index at the close of the last trading day of the contract and
the price at which the agreement is made. No physical delivery of the
underlying stocks in the index is made. When the futures contract is entered
into, each party deposits with a broker or in a segregated custodial account
approximately 5% of the contract amount, called the "initial margin."
Subsequent payments to and from the broker, called "variation margin," will be
made on a daily basis as the price of the underlying stock index fluctuates
making the long and short positions in the futures contracts more or less
valuable, a process known as "marked to the market." In the case of options on
stock index futures, the holder of the option pays a premium and receives the
right, upon exercise of the option at a specified price during the option
period, to assume a position in a stock index futures contract (a long
position if the option is a call and a short position if the option is a put).
If the option is exercised by the holder before the last trading day during
the option period, the option writer delivers the futures position, as well as
any balance in the writer's futures margin account. If it is exercised on the
last trading day, the option writer delivers to the option holder cash in an
amount equal to the difference between the option exercise price and the
closing level of the relevant index on the date the option expires.     
 
                                      B-3
<PAGE>
 
   
  The Fund intends to engage in stock index futures and options on stock index
futures transactions as a hedge against changes resulting from market
conditions in the values of securities which are held in the Fund's portfolio
or which the Fund intends to purchase, in accordance with the rules and
regulations of the Commodity Futures Trading Commission (the CFTC). The Fund
also intends to engage in such transactions when they are economically
appropriate for the reduction of risks inherent in the ongoing management of
the Fund's portfolio or for return enhancement.     
 
  The Fund's successful use of stock index futures contracts, options on such
contracts and options on indices depends upon the investment adviser's ability
to predict the direction of the market and is subject to various additional
risks. The correlation between movements in the price of the stock index
future and the price of the securities being hedged is imperfect and the risk
from imperfect correlation increases as the composition of the Fund's
portfolio diverges from the composition of the relevant index. In addition, if
the Fund purchases futures to hedge against market advances before it can
invest in common stock in an advantageous manner and the market declines, the
Fund might create a loss on the futures contract. Particularly in the case of
options on stock index futures and on stock indices, the Fund's ability to
establish and maintain positions will depend on market liquidity. In addition,
the ability of the Fund to close out a futures position or an option depends
on a liquid secondary market. There is no assurance that liquid secondary
markets will exist for any particular futures contract or option at any
particular time. See "Limitations on Purchase and Sale of Stock Options and
Options on Stock Indices and Foreign Currencies," "Risks of Options on Foreign
Currencies" and "Risks of Options on Indices" below. During the coming year,
the Fund will not enter into futures contracts on stock indices or options
thereon if the aggregate margin and premiums on such options exceed 5% of the
Fund's total assets.
 
RISKS OF TRANSACTIONS IN OPTIONS
 
  An option position may be closed out only on an exchange, board of trade or
other trading facility which provides a secondary market for an option of the
same series. Although the Fund will generally purchase or write only those
options for which there appears to be an active secondary market, there is no
assurance that a liquid secondary market on an exchange will exist for any
particular option, or at any particular time, and for some options no
secondary market on an exchange or otherwise may exist. In such event it might
not be possible to effect closing transactions in particular options, with the
result that the Fund would have to exercise its options in order to realize
any profit and would incur brokerage commissions upon the exercise of call
options and upon the subsequent disposition of underlying securities acquired
through the exercise of call options or upon the purchase of underlying
securities for the exercise of put options. If the Fund as a covered call
option writer is unable to effect a closing purchase transaction in a
secondary market, it will not be able to sell the underlying security until
the option expires or it delivers the underlying security upon exercise.
 
  Reasons for the absence of a liquid secondary market on an exchange include
the following: (i) there may be insufficient trading interest in certain
options; (ii) restrictions may be imposed by an exchange on opening
transactions or closing transactions or both; (iii) trading halts, suspensions
or other restrictions may be imposed with respect to particular classes or
series of options or underlying securities; (iv) unusual or unforeseen
circumstances may interrupt normal operations on an exchange; (v) the
facilities of an exchange or a clearing corporation may not at all times be
adequate to handle current trading volume; or (vi) one or more exchanges
could, for economic or other reasons, decide or be compelled at some future
date to discontinue the trading of options (or a particular class or series of
options), in which event the secondary market on that exchange (or in the
class or series of options) would cease to exist, although outstanding options
on that exchange that had been issued by a clearing corporation as a result of
trades on that exchange would continue to be exercisable in accordance with
their terms. There is no assurance that higher than anticipated trading
activity or other unforeseen events might not, at times, render certain of the
facilities of any of the clearing corporations inadequate, and thereby result
in the institution by an exchange of special procedures which may interfere
with the timely execution of customers' orders. The Fund intends to purchase
and sell only those options which are cleared by clearinghouses whose
facilities are considered to be adequate to handle the volume of options
transactions.
 
RISKS OF OPTIONS ON INDICES
 
  The Fund's purchase and sale of options on indices will be subject to risks
described above under "Risks of Transactions in Options." In addition, the
distinctive characteristics of options on indices create certain risks that
are not present with stock options.
 
  Index prices may be distorted if trading of certain stocks included in the
index is interrupted. Trading in the index options also may be interrupted in
certain circumstances, such as if trading were halted in a substantial number
of stocks included in the index. If this occurred, the Fund would not be able
to close out options which it had purchased or written and, if restrictions on
exercise
 
                                      B-4
<PAGE>
 
were imposed, may be unable to exercise an option it holds, which could result
in substantial losses to the Fund. It is the Fund's policy to purchase or
write options only on indices which include a number of stocks sufficient to
minimize the likelihood of a trading halt in the index.
 
  The ability to establish and close out positions on such options will be
subject to the development and maintenance of a liquid secondary market. It is
not certain that this market will develop in all index option contracts. The
Fund will not purchase or sell any index option contract unless and until, in
the investment adviser's opinion, the market for such options has developed
sufficiently that the risk in connection with such transactions is no greater
than the risk in connection with options on stocks.
 
  SPECIAL RISKS OF WRITING CALLS ON INDICES. Because exercises of index
options are settled in cash, a call writer such as the Fund cannot determine
the amount of its settlement obligations in advance and, unlike call writing
on specific stocks, cannot provide in advance for, or cover, its potential
settlement obligations by acquiring and holding the underlying securities.
However, the Fund will write call options on indices only under the
circumstances described below under "Limitations on Purchase and Sale of Stock
Options and Options on Stock Indices and Foreign Currencies."
 
  Price movements in the Fund's portfolio probably will not correlate
precisely with movements in the level of the index and, therefore, the Fund
bears the risk that the price of the securities held by the Fund may not
increase as much as the index. In such event, the Fund would bear a loss on
the call which is not completely offset by movements in the price of the
Fund's portfolio. It is also possible that the index may rise when the Fund's
portfolio of stocks does not rise. If this occurred, the Fund would experience
a loss on the call which would not be offset by an increase in the value of
its portfolio and might also experience a loss in its portfolio. However,
because the value of a diversified portfolio will, over time, tend to move in
the same direction as the market, movements in the value of the Fund in the
opposite direction as the market would be likely to occur for only a short
period or to a small degree.
 
  Unless the Fund has other liquid assets which are sufficient to satisfy the
exercise of a call, the Fund would be required to liquidate portfolio
securities in order to satisfy the exercise. Because an exercise must be
settled within hours after receiving the notice of exercise, if the Fund fails
to anticipate an exercise, it may have to borrow from a bank (in amounts not
exceeding 20% of the Fund's total assets) pending settlement of the sale of
securities in its portfolio and would incur interest charges thereon.
 
  When the Fund has written a call, there is also a risk that the market may
decline between the time the Fund has a call exercised against it, at a price
which is fixed as of the closing level of the index on the date of exercise,
and the time the Fund is able to sell stocks in its portfolio. As with stock
options, the Fund will not learn that an index option has been exercised until
the day following the exercise date but, unlike a call on stock where the Fund
would be able to deliver the underlying securities in settlement, the Fund may
have to sell part of its investment portfolio in order to make settlement in
cash, and the price of such investments might decline before they can be sold.
This timing risk makes certain strategies involving more than one option
substantially more risky with index options than with stock options. For
example, even if an index call which the Fund has written is "covered" by an
index call held by the Fund with the same strike price, the Fund will bear the
risk that the level of the index may decline between the close of trading on
the date the exercise notice is filed with the clearing corporation and the
close of trading on the date the Fund exercises the call it holds or the time
the Fund sells the call, which, in either case, would occur no earlier than
the day following the day the exercise notice was filed.
 
  SPECIAL RISKS OF PURCHASING PUTS AND CALLS. If the Fund holds an index
option and exercises it before final determination of the closing index value
for that day, it runs the risk that the level of the underlying index may
change before closing. If such a change causes the exercised option to fall
out-of-the-money, the Fund will be required to pay the difference between the
closing index value and the exercise price of the option (times the applicable
multiplier) to the assigned writer. Although the Fund may be able to minimize
this risk by withholding exercise instructions until just before the daily
cutoff time or by selling rather than exercising an option when the index
level is close to the exercise price, it may not be possible to eliminate this
risk entirely because the cutoff times for index options may be earlier than
those fixed for other types of options and may occur before definitive closing
index values are announced.
 
RISKS OF OPTIONS ON FOREIGN CURRENCIES
 
  Because there are two currencies involved, developments in either or both
countries can affect the values of options on foreign currencies. Risks
include those described in the Prospectus under "How the Fund Invests--
Investment Objective and Policies--Special Considerations and Risks,"
including government actions affecting currency valuation and the movements of
currencies
 
                                      B-5
<PAGE>
 
from one country to another. The quantities of currency underlying option
contracts represent odd lots in a market dominated by transactions between
banks; this can mean extra transaction costs upon exercise. Option markets may
be closed while round-the-clock interbank currency markets are open, and this
can create price and rate discrepancies.
 
RISKS RELATED TO FORWARD CURRENCY EXCHANGE CONTRACTS
 
  The Fund may enter into forward foreign currency exchange contracts in
several circumstances. When the Fund enters into a contract for the purchase
or sale of a security denominated in a foreign currency, or when the Fund
anticipates the receipt in a foreign currency of dividends or interest
payments on a security which it holds, the Fund may desire to "lock-in" the
U.S. dollar price of the security or the U.S. dollar equivalent of such
dividend or interest payment, as the case may be. By entering into a forward
contract for a fixed amount of dollars, for the purchase or sale of the amount
of foreign currency involved in the underlying transactions, the Fund will be
able to protect itself against a possible loss resulting from an adverse
change in the relationship between the U.S. dollar and the subject foreign
currency during the period between the date on which the security is purchased
or sold, or on which the dividend or interest payment is declared, and the
date on which such payments are made or received.
   
  Additionally, when the investment adviser believes that the currency of a
particular foreign country may suffer a substantial decline against the U.S.
dollar, the Fund may enter into a forward contract for a fixed amount of
dollars, to sell the amount of foreign currency approximating the value of
some or all of the Fund's portfolio securities denominated in such foreign
currency. The precise matching of the forward contract amounts and the value
of the securities involved will not generally be possible since the future
value of securities in foreign currencies will change as a consequence of
market movements in the value of those securities between the date on which
the forward contract is entered into and the date it matures. The projection
of short-term currency market movement is extremely difficult, and the
successful execution of a short-term hedging strategy is highly uncertain. The
Fund does not intend to enter into such forward contracts to protect the value
of its portfolio securities on a regular or continuous basis. The Fund will
also not enter into such forward contracts or maintain a net exposure to such
contracts where the consummation of the contracts would obligate the Fund to
deliver an amount of foreign currency in excess of the value of the Fund's
portfolio securities or other assets denominated in that currency. Under
normal circumstances, consideration of the prospect for currency parities will
be incorporated into the long-term investment decisions made with regard to
overall diversification strategies. However, the Fund believes that it is
important to have the flexibility to enter into such forward contracts when it
determines that the best interests of the Fund will thereby be served. If the
Fund enters into a position hedging transaction, the transaction will be
"covered" by the position being hedged or the Fund's Custodian or subcustodian
will place cash, U.S. Government obligations or other liquid, unencumbered
assets in a segregated account of the Fund (less the value of the "covering"
positions, if any) in an amount equal to the value of the Fund's total assets
committed to the consummation of the given forward contract. The assets placed
in the segregated account will be marked to market daily, and if the value
declines, additional cash or securities will be placed in the account so that
the value of the account will, at all times, equal the amount of the Fund's
net commitment with respect to the forward contract. The Fund's ability to
enter into forward foreign currency exchange contracts may be limited by
certain requirements for qualification as a regulated investment company under
the Internal Revenue Code. See "Taxes, Dividends and Distributions" herein.
    
  The Fund generally will not enter into a forward contract with a term of
greater than one year. At the maturity of a forward contract, the Fund may
either sell the portfolio security and make delivery of the foreign currency,
or it may retain the security and terminate its contractual obligation to
deliver the foreign currency by purchasing an "offsetting" contract with the
same currency trader obligating it to purchase, on the same maturity date, the
same amount of the foreign currency.
 
  It is impossible to forecast with absolute precision the market value of a
particular portfolio security at the expiration of the contract. Accordingly,
it may be necessary for the Fund to purchase additional foreign currency on
the spot market (and bear the expense of such purchase) if the market value of
the security is less than the amount of foreign currency that the Fund is
obligated to deliver and if a decision is made to sell the security and make
delivery of the foreign currency.
 
  If the Fund retains the portfolio security and engages in an offsetting
transaction, the Fund will incur a gain or a loss to the extent that there has
been movement in forward contract prices. Should forward contract prices
decline during the period between the Fund's entering into a forward contract
for the sale of a foreign currency and the date it enters into an offsetting
contract for the purchase of the foreign currency, the Fund will realize a
gain to the extent that the price of the currency it has agreed to sell
exceeds the price of the currency it has agreed to purchase. Should forward
contract prices increase, the Fund will suffer a loss to the extent that the
price of the currency it has agreed to purchase exceeds the price of the
currency it has agreed to sell.
 
  The Fund's dealings in forward foreign currency exchange contracts will be
limited to the transactions described above. Of course, the Fund is not
required to enter into such transactions with regard to its foreign currency-
denominated securities. It also should be realized that this method of
protecting the value of the Fund's portfolio securities against a decline in
the value of a currency does not eliminate fluctuations in the underlying
prices of the securities which are unrelated to exchange rates.
 
                                      B-6
<PAGE>
 
Additionally, although such contracts tend to minimize the risk of loss due to
a decline in the value of the hedged currency, at the same time they tend to
limit any potential gain which might result should the value of such currency
increase.
 
  Although the Fund values its assets daily in terms of U.S. dollars, it does
not intend physically to convert its holdings of foreign currencies into U.S.
dollars on a daily basis. It will do so from time to time, and investors
should be aware of the costs of currency conversion. Although foreign exchange
dealers do not charge a fee for conversion, they do realize a profit based on
the difference (the spread) between the prices at which they are buying and
selling various currencies. Thus, a dealer may offer to sell a foreign
currency to the Fund at one rate, while offering a lesser rate of exchange
should the Fund desire to resell that currency to the dealer.
 
RISKS OF TRANSACTIONS IN FUTURES CONTRACTS
 
  There are several risks in connection with the use of futures contracts as a
hedging device. Due to the imperfect correlation between the price of futures
contracts and movements in the currency or group of currencies, the price of a
futures contract may move more or less than the price of the currencies being
hedged. In the case of futures contracts on stock indices, the correlation
between the price of the futures contract and the movements in the index may
not be perfect. Therefore, a correct forecast of currency rates, market trends
or international political trends by the investment adviser may still not
result in a successful hedging transaction.
 
  Although the Fund will purchase or sell futures contracts only on exchanges
where there appears to be an adequate secondary market, there is no assurance
that a liquid secondary market on an exchange will exist for any particular
contract or at any particular time. Accordingly, there can be no assurance
that it will be possible, at any particular time, to close a futures position.
In the event the Fund could not close a futures position and the value of such
position declined, the Fund would be required to continue to make daily cash
payments of variation margin. There is no guarantee that the price movements
of the portfolio securities denominated in foreign currencies will, in fact,
correlate with the price movements in the futures contract and thus provide an
offset to losses on a futures contract. Currently, futures contracts are
available on the Australian Dollar, British Pound, Canadian Dollar, Japanese
Yen, Swiss Franc, German Mark and Eurodollar, among others. Futures contracts
are also available on the S&P 500 Stock Index, the NYSE Composite Index and
the Major Market Index and other global exchanges.
 
  Under regulations of the Commodity Exchange Act, investment companies
registered under the Investment Company Act of 1940, as amended (the
Investment Company Act), are exempt from the definition of "commodity pool
operator," subject to compliance with certain conditions. The exemption is
conditioned upon the Fund's purchasing and selling futures contracts and
options thereon for bona fide hedging transactions, except that the Fund may
purchase and sell futures contracts and options thereon for any other purpose
to the extent that the aggregate initial margin and option premiums do not
exceed 5% of the liquidation value of the Fund's total assets. The Fund will
use currency futures and options on such futures in a manner consistent with
these requirements.
 
  Successful use of futures contracts by the Fund is also subject to the
ability of the Fund's investment adviser to predict correctly movements in the
direction of markets and other factors affecting currencies or the stock
market generally. For example, if the Fund has hedged against the possibility
of an increase in currency rates which would adversely affect the price of
securities in its portfolio and the price of such securities increases
instead, the Fund will lose part or all of the benefit of the increased value
of its securities because it will have offsetting losses in its futures
positions. In addition, in such situations, if the Fund has insufficient cash
to meet daily variation margin requirements, it may need to sell securities to
meet such requirements. Such sales of securities may be, but will not
necessarily be, at increased prices which reflect the rising market. The Fund
may have to sell securities at a time when it is disadvantageous to do so.
 
  The hours of trading of futures contracts may not conform to the hours
during which the Fund may trade the underlying securities. To the extent that
the futures markets close before the securities markets, significant price and
rate movements can take place in the securities markets that cannot be
reflected in the futures markets.
 
OPTIONS ON FUTURES CONTRACTS
 
  An option on a futures contract gives the purchaser the right, but not the
obligation, to assume a position in a futures contract (a long position if the
option is a call and a short position if the option is a put) at a specified
exercise price at any time during the option exercise period. The writer of
the option is required upon exercise to assume an offsetting futures position
(a short position if the option is a call and a long position if the option is
a put). Upon exercise of the option, the assumption of offsetting futures
positions by the writer and holder of the option will be accompanied by
delivery of the accumulated cash balance in the writer's
 
                                      B-7
<PAGE>
 
futures margin account which represents the amount by which the market price
of the futures contract, at exercise, exceeds, in the case of a call, or is
less than, in the case of a put, the exercise price of the option on the
futures contract. Currently options can be purchased or written with respect
to futures contracts on the Australian Dollar, British Pound, Canadian Dollar,
Japanese Yen, Swiss Franc, German Mark and Eurodollar, among others. With
respect to stock indices, options are traded on futures contracts for the S&P
500 Stock Index and the NYSE Composite Index and other global indices.
 
  The holder or writer of an option may terminate its position by selling or
purchasing an option of the same series. There is no guarantee that such
closing transactions can be effected.
 
LIMITATIONS ON PURCHASE AND SALE OF STOCK OPTIONS AND OPTIONS ON STOCK INDICES
AND FOREIGN CURRENCIES
   
  The Fund may write put and call options on stocks only if they are covered,
and such options must remain covered so long as the Fund is obligated as a
writer. The Fund will write put options on stock indices and foreign
currencies only if they are covered by segregating with the Fund's Custodian
an amount of cash or short-term investments equal to the aggregate exercise
price of the puts.     
   
  Except as described below, the Fund will write call options on indices only
if on such date it holds a portfolio of stocks at least equal to the value of
the index times the multiplier times the number of contracts. When the Fund
writes a call option on a broadly-based stock market index, the Fund will
segregate or put into escrow with its Custodian, or pledge to a broker as
collateral for the option, cash, U.S. Government securities, liquid assets or
at least one "qualified security" with a market value at the time the option
is written of not less than 100% of the current index value times the
multiplier times the number of contracts.     
   
  If the Fund has written an option on an industry or market segment index, it
will so segregate or put into escrow with its Custodian, or pledge to a broker
as collateral for the option, at least ten "qualified securities," which are
stocks of issuers in such industry or market segment, with a market value at
the time the option is written of not less than 100% of the current index
value times the multiplier times the number of contracts. Such stocks will
include stocks which represent at least 50% of the weighting of the industry
or market segment index and will represent at least 50% of the Fund's holdings
in that industry or market segment. No individual security will represent more
than 15% of the amount so segregated, pledged or escrowed in the case of
broadly-based stock market index options or 25% of such amount in the case of
industry or market segment index options. If at the close of business on any
day the market value of such qualified securities so segregated, escrowed or
pledged falls below 100% of the current index value times the multiplier times
the number of contracts, the Fund will so segregate, escrow or pledge an
amount in cash, Treasury bills or other liquid assets equal in value to the
difference. In addition, when the Fund writes a call on an index which is in-
the-money at the time the call is written, the Fund will segregate with its
Custodian or pledge to the broker as collateral cash, U.S. Government
securities or other liquid assets equal in value to the amount by which the
call is in-the-money times the multiplier times the number of contracts. Any
amount segregated pursuant to the foregoing sentence may be applied to the
Fund's obligation to segregate additional amounts in the event that the market
value of the qualified securities falls below 100% of the current index value
times the multiplier times the number of contracts. A "qualified security" is
an equity security which is listed on a national securities exchange or listed
on the National Association of Securities Dealers Automated Quotation System
against which the Fund has not written a stock call option and which has not
been hedged by the Fund by the sale of stock index futures. However, if the
Fund holds a call on the same index as the call written where the exercise
price of the call held is equal to or less than the exercise price of the call
written or greater than the exercise price of the call written if the
difference is maintained by the Fund in cash, Treasury bills or other high
grade short-term obligations in a segregated account with its Custodian, it
will not be subject to the requirements described in this paragraph.     
 
  POSITION LIMITS. Transactions by the Fund in futures contracts and options
will be subject to limitations, if any, established by each of the exchanges,
boards of trade or other trading facilities (including NASDAQ) governing the
maximum number of options in each class which may be written or purchased by a
single investor or group of investors acting in concert, regardless of whether
the options are written on the same or different exchanges, boards of trade or
other trading facilities or are held or written in one or more accounts or
through one or more brokers. Thus, the number of futures contracts and options
which the Fund may write or
purchase may be affected by the futures contracts and options written or
purchased by other investment advisory clients of the investment adviser. An
exchange, board of trade or other trading facility may order the liquidation
of positions found to be in excess of these limits, and it may impose certain
other sanctions.
 
DEFENSIVE STRATEGY AND SHORT-TERM INVESTMENTS
 
  When conditions dictate a temporary defensive strategy or during periods of
portfolio structuring or restructuring, the Fund may invest more than 35% of
its total assets in money market instruments, including commercial paper of
domestic corporations,
 
                                      B-8
<PAGE>
 
certificates of deposit, bankers' acceptances and other obligations of
domestic and foreign banks, and obligations issued or guaranteed by the U.S.
Government, its agencies or its instrumentalities. Such investments may be
subject to certain risks, including future political and economic
developments, the possible imposition of withholding taxes on interest income,
the seizure or nationalization of foreign deposits and foreign exchange
controls or other restrictions.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
   
  From time to time, in the ordinary course of business, the Fund may purchase
securities on a when-issued or delayed delivery basis; that is, delivery and
payment can take place in the future after the date of the transaction. The
Fund will make commitments for such when-issued or delayed delivery
transactions only with the intention of actually acquiring the securities. The
Fund's Custodian will maintain, in a separate account of the Fund, cash, U.S.
Government securities, equity securities or other liquid unencumbered assets
marked-to market daily having a value equal to or greater than such
commitments. If the Fund chooses to dispose of the right to acquire a when-
issued or delayed delivery 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 Fund does not intend to have more than 5% of its
net assets (determined at the time of entering into the transaction) involved
in transactions on a when-issued or delayed delivery basis during the coming
year.     
 
SHORT SALES AGAINST-THE-BOX
 
  The Fund may make short sales of securities or maintain a short position,
provided that at all times when a short position is open the Fund owns an
equal amount of such securities or securities convertible into or
exchangeable, without payment of any further consideration, for an equal
amount of the securities of the same issuer as the securities sold short (a
short sale against-the-box), and that not more than 25% of the Fund's net
assets (determined at the time of the short sale) may be subject to such
sales. Short sales will be made primarily to defer realization of gain or loss
for federal tax purposes. The Fund does not intend to have more than 5% of its
net assets (determined at the time of the short sale) subject to short sales
against-the-box during the coming year.
 
REPURCHASE AGREEMENTS
 
  The Fund's repurchase agreements will be collateralized by U.S. Government
obligations. The Fund will enter into repurchase transactions only with
parties meeting creditworthiness standards approved by the Fund's Board of
Directors. The Fund's investment adviser will monitor the creditworthiness of
such parties, under the general supervision of the Board of Directors. In the
event of a default or bankruptcy by a seller, the Fund 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 repurchase price, the Fund will suffer a loss.
   
  The Fund participates in a joint repurchase account with other investment
companies managed by Prudential Investments Fund Management LLC (PIFM)
pursuant to an order of the Securities and Exchange Commission (SEC). On a
daily basis, any uninvested cash balances of the Fund may be aggregated with
those of such 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.     
 
LENDING OF PORTFOLIO SECURITIES
   
  The Fund may lend its portfolio securities to brokers, dealers and financial
institutions, provided that outstanding loans do not exceed in the aggregate
30% of the value of the Fund's total assets and provided that such loans are
callable at any time by the Fund and are at all times secured by cash or
equivalent collateral (which may include a secured letter of credit) that is
equal to at least the market value, determined daily, of the loaned
securities. The advantage of such loans is that the Fund continues to receive
payments in lieu of the interest and dividends of 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
the Fund at any time. If the borrower fails to maintain the requisite amount
of collateral, the loan automatically terminates and the Fund can 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 Fund, and any gain or loss in the market price during the
loan would inure to the Fund.
 
                                      B-9
<PAGE>
 
  Since voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loan, in whole or in
part as may be appropriate, to permit the exercise of such rights if the
matters involved would have a material effect on the Fund's investment in the
securities which are the subject of the loan. The Fund 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.
 
WARRANTS
 
  The Fund will not invest more than 5% of its net assets in warrants, nor
will it invest more than 2% of its net assets in warrants which are not listed
on the New York or American Stock Exchange. In the application of such
limitation, warrants will be valued at the lower of cost or market value,
except that warrants acquired by the Fund in units or attached to other
securities will be deemed to be without value.
 
SECURITIES OF OTHER INVESTMENT COMPANIES
 
  The Fund may invest up to 5% of its total assets in securities of other
registered investment companies. Generally, the Fund does not intend to invest
in such securities. If the Fund does invest in securities of other registered
investment companies, shareholders of the Fund may be subject to duplicate
management and advisory fees.
 
ILLIQUID SECURITIES
   
  The Fund may not hold more than 15% of its net assets in repurchase
agreements which have a maturity of longer than seven days or in other
illiquid securities, including securities that are illiquid by virtue of the
absence of a readily available market (either within or outside of the United
States) or legal or contractual restrictions on resale. 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, convertible 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 investments.
 
  Rule 144A under 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
 
                                     B-10
<PAGE>
 
unrated, be of comparable quality in the view of the investment adviser, and
(ii) it must not be "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.
   
 The staff of the SEC has taken the position that purchased over-the-counter
options and the assets used as "cover" for written over-the-counter options
are illiquid securities unless the Fund and the counterparty have provided for
the Fund, at the Fund's election, to unwind the over-the-counter option. The
exercise of such an option ordinarily would involve the payment by the Fund of
an amount designed to reflect the counterparty's economic loss from an early
termination, but does allow the Fund to treat the assets used as "cover" as
"liquid."     
 
PORTFOLIO TURNOVER
   
  As a result of the investment policies described above, the Fund may engage
in a substantial number of portfolio transactions, but the Fund's portfolio
turnover rate is not expected to exceed 200%. The portfolio turnover rate is
generally the percentage computed by dividing the lesser of portfolio
purchases or sales (excluding all securities, including options, whose
maturities or expiration dates at acquisition were one year or less) by the
monthly average value of the portfolio. High portfolio turnover involves
correspondingly greater brokerage commissions and other transaction costs,
which are borne directly by the Fund. In addition, high portfolio turnover may
also mean that a proportionately greater amount of distributions to
shareholders will be taxed as ordinary income rather than long-term capital
gains compared to investment companies with lower portfolio turnover. See
"Portfolio Transactions and Brokerage" and "Taxes, Dividends and
Distributions." For the fiscal years ended May 31, 1997 and May 31, 1996, the
Fund's portfolio turnover rates were 53% and 41%, respectively.     
 
                            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 Fund's outstanding voting securities. A "majority of the
Fund's 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.
 
  The Fund may not:
 
  1. Purchase securities on margin (but the Fund may obtain such short-term
credits as may be necessary for the clearance of transactions); provided that
the deposit or payment by the Fund of initial or maintenance margin in
connection with futures or options is not considered the purchase of a
security on margin.
 
  2. Make short sales of securities or maintain a short position, except short
sales against-the-box.
 
  3. Issue senior securities, borrow money or pledge its assets, except that
the Fund may borrow up to 20% of the value of its total assets (calculated
when the loan is made) for temporary, extraordinary or emergency purposes or
for the clearance of transactions. The Fund may pledge up to 20% of the value
of its total assets to secure such borrowings. For purposes of this
restriction, the purchase or sale of securities on a when-issued or delayed
delivery basis, forward foreign currency exchange contracts and collateral and
collateral arrangements relating thereto, and collateral arrangements with
respect to futures contracts and options thereon and with respect to the
writing of options and obligations of the Fund to Directors pursuant to
deferred compensation arrangements are not deemed to be a pledge of assets or
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: (i) with respect to 75% of the
Fund's total assets, more than 5% of the Fund's total assets (determined at
the time of investment) would then be invested in securities of a single
issuer, or (ii) 25% or more of the Fund's total assets (determined at the time
of investment) would be invested in a single industry.
 
  5. Purchase any security if as a result the Fund would then hold more than
10% of the outstanding voting securities of an issuer.
 
  6. Buy or sell real estate or interests in real estate, except that the Fund
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. The Fund may not purchase
interests in real estate limited partnerships which are not readily
marketable.
 
  7. Buy or sell commodities or commodity contracts. (For purposes of this
restriction, futures contracts on currencies and on stock indices and forward
foreign currency exchange contracts are not deemed to be commodities or
commodity contracts.)
 
 
                                     B-11
<PAGE>
 
  8. 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.
 
  9. Make investments for the purpose of exercising control or management.
 
  10. 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 5% 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.
 
  11. Invest in interests in oil, gas or other mineral exploration or
development programs, except that the Fund may invest in the securities of
companies which invest in or sponsor such programs.
   
  12. Make loans, except through (i) repurchase agreements and (ii) loans of
portfolio securities (limited to 30% of the Fund's total assets).     
 
  13. Purchase any security if as a result the Fund would then have more than
5% of its total assets (determined at the time of the investment) invested in
securities of companies (including predecessors) less than three years old,
except that the Fund may invest in the securities of any U.S. Government
agency or instrumentality, and in any security guaranteed by such agency or
instrumentality and except that the Fund may invest in securities rated in the
top three grades by a nationally recognized rating agency.
       
  Whenever any fundamental investment policy or investment restriction states
a maximum percentage of the Fund's 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 the
Fund's asset coverage for borrowings falls below 300%, the Fund will take
prompt action to reduce its borrowings, as required by applicable law.
 
NATURAL RESOURCE COMPANIES
 
  The Fund will generally invest a substantial majority of its total assets in
securities of natural resource companies. With respect to Investment
Restriction No. 4, the following categories will be considered separate and
distinct industries: integrated oil/domestic, integrated oil/international,
crude oil production, natural gas production, gas pipeline, oil service,
Canadian oil and gas, Australian oil and gas, coal, forest products, paper,
foods (including corn and wheat), aluminum, copper, all other basic metals
(e.g., nickel, steel, lead), gold, silver, platinum, mining finance,
plantations (e.g., edible oils), mineral sands, and diversified resources. A
company will be deemed to be in a particular industry if the majority of its
revenues is derived from one of the categories described in the preceding
sentence.
 
  The Board of Directors will review these industry classifications from time
to time to determine whether they are reasonable under the circumstances and
may change such classifications, without shareholder approval, to the extent
necessary.

    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) by reason of his affiliation with
   Prudential, Prudential Securities of PIFM.     
 
 
  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.
 
  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.
 
                                     B-14

  The Board of Directors has 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. Eyre
and Beach are scheduled to retire on December 31, 1998 and 1999, respectively.
    
          
   Pursuant to the terms of the Management Agreement with the Fund, the
Manager pays all compensation of officers and employees of the Fund as well as
the fees and expenses of all Directors of the Fund who are affiliated persons
of the Manager. The Fund pays each of its Directors who is not an affiliated
person of PIFM annual compensation of $3,500, 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 the Board of
which the Director will be asked to serve.     
 
  Directors may receive their Directors' fees pursuant to a deferred fee
agreement with the Fund. Under the terms of the agreement, the Fund accrues
daily the amount of such Directors' fees 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. 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.
          
  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 May 31, 1997 and the aggregate compensation paid to such Directors for
service on the Fund's Board and that of all other investment companies managed
by PIFM (Fund Complex) for the calendar year ended December 31, 1996. In
October 1996, shareholders elected a new Board of Directors. Below are listed
the Directors who have served the Fund during its most recent fiscal year, as
well as the new Directors who took office at the shareholder meeting in
October.

                                    MANAGER
   
  The manager of the Fund is Prudential Investments Fund Management LLC
(formerly Prudential Mutual Fund Management LLC) (PIFM or the Manager),
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 Fund, comprise the Prudential Mutual Funds. See "How the Fund is Managed--
Manager" in the Prospectus. As of June 30, 1997, PIFM managed and/or
administered open-end and closed-end management investment companies with
assets of approximately $56.7 billion. According to the Investment Company
Institute, as of December 31, 1996, the Prudential Mutual Funds were the 15th
largest family of mutual funds in the United States.     
   
  PIFM is a subsidiary of Prudential Securities and Prudential. 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 with the Fund (the Management
Agreement), PIFM, subject to the supervision of the Fund's Board of Directors
and in conformity with the stated policies of the Fund, manages both the
investment operations of the Fund and the composition of the Fund's portfolio,
including the purchase, retention, disposition and loan of securities. In
connection therewith, PIFM is obligated to keep certain books and records of
the Fund. PIFM also administers the Fund's corporate affairs and, in
connection therewith, furnishes the Fund with office facilities, together with
those ordinary clerical and bookkeeping services which are not being furnished
by State Street Bank and Trust Company, the Fund's custodian, and PMFS, the
Fund's transfer and dividend disbursing agent. The management services of PIFM
for the Fund 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, a fee
at an annual rate of .75 of 1% of the Fund's average daily net assets. The fee
is computed daily and payable monthly. The Management Agreement also provides
that, in the event the expenses of the Fund (including the fees of 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) for any fiscal year
exceed the lowest applicable annual expense limitation established and
enforced pursuant to the statutes or regulations of any jurisdiction in which
the Fund's shares are qualified for offer and sale, the compensation due to
PIFM will be reduced by the amount of such excess. Reductions in excess of the
total compensation payable to PIFM will be paid by PIFM to the Fund. No such
reductions were required during the fiscal year ended May 31, 1997. No
jurisdiction currently limits the Fund's expenses.     
 
  In connection with its management of the corporate affairs of the Fund, PIFM
bears the following expenses:
   
  (a) the salaries and expenses of all of its and the Fund's personnel except
the fees and expenses of Directors who are not affiliated persons of PIFM or
the Fund's investment adviser;     
   
  (b) all expenses incurred by PIFM or by the Fund in connection with managing
the ordinary course of the Fund's business, other than those assumed by the
Fund 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
the subadvisory agreement between PIFM and PI (the Subadvisory Agreement).
    
  Under the terms of the Management Agreement, the Fund is responsible for the
payment of the following expenses: (a) the fees payable to the Manager, (b)
the fees and expenses of Directors who are not affiliated persons of the
Manager or the Fund's investment adviser, (c) the fees and certain expenses of
the Custodian and Transfer and Dividend Disbursing Agent, including the cost
of providing records to the Manager in connection with its obligation of
maintaining required records of the Fund and of pricing the Fund's shares, (d)
the charges and expenses of legal counsel and independent accountants for the
Fund, (e) brokerage
 
                                     B-16
<PAGE>
 
   
commissions and any issue or transfer taxes chargeable to the Fund in
connection with its securities transactions, (f) all taxes and corporate fees
payable by the Fund to governmental agencies, (g) the fees of any trade
associations of which the Fund may be a member, (h) the cost of stock
certificates representing shares of the Fund, (i) the cost of fidelity and
liability insurance, (j) the fees and expenses involved in registering and
maintaining registration of the Fund 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 in the amount necessary for
distribution to the shareholders, (l) litigation and indemnification expenses
and other extraordinary expenses not incurred in the ordinary course of the
Fund's business and (m) distribution fees.     
   
  The Management Agreement provides that PIFM will not be liable for any error
of judgment or for any loss suffered by the Fund in connection with the
matters to which the Management Agreement relates, except a loss resulting
from willful misfeasance, bad faith, gross negligence or reckless disregard of
duty. The Management Agreement provides that it will terminate automatically
if assigned, and that it may be terminated without penalty by either party
upon not more than 60 days' nor less than 30 days' written notice. The
Management Agreement will continue in effect for a period of more than two
years from the date of execution only so long as such continuance is
specifically approved at least annually in conformity with the Investment
Company Act. The Management Agreement was last approved by the Board of
Directors of the Fund, including a majority of the Directors who are not
parties to the contract or interested persons of any such party, as defined in
the Investment Company Act, on May 29, 1997 and by shareholders of the Fund on
February 19, 1988.     
   
  For the fiscal years ended May 31, 1997, 1996 and 1995, the Fund paid
management fees to PIFM of $1,128,718, $811,776 and $642,865, respectively.
       
  PIFM has entered into the Subadvisory Agreement with PI. The Subadvisory
Agreement provides that PI will furnish investment advisory services in
connection with the management of the Fund. In connection therewith, PI is
obligated to keep certain books and records of the Fund. 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 those services.     
   
  The Subadvisory Agreement was last approved by the Board of Directors,
including a majority of the Directors who are not parties to the contract or
interested persons of any such party as defined in the Investment Company Act,
on May 29, 1997, and by shareholders of the Fund on February 19, 1988.     
   
  The Subadvisory Agreement provides that it will terminate in the event of
its assignment (as defined in the Investment Company Act) or upon the
termination of the Management 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
   
  Prudential Securities Incorporated (Prudential Securities, PSI or the
Distributor), One Seaport Plaza, New York, New York 10292, acts as the
distributor of the shares of the Fund.     
   
  Pursuant to separate Distribution and Service Plans (the Class A Plan, the
Class B Plan and the Class C Plan, collectively, the Plans) adopted by the
Fund under Rule 12b-1 under the Investment Company Act and a distribution
agreement (the Distribution Agreement), Prudential Securities (the
Distributor) incurs the expenses of distributing the Fund's Class A, Class B
and Class C shares. Prudential Securities also incurs the expenses of
distributing the Fund's Class Z shares under the Distribution Agreement, none
of which are reimbursed by or paid for by the Fund. See "How the Fund is
Managed--Distributor" in the Prospectus.     
 
  Prior to January 22, 1990, the Fund offered only one class of shares (the
then existing Class B shares). On October 11, 1989, the Board of Directors,
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 Class A or Class B Plan or in any agreement related to either Plan (the
Rule 12b-1 Directors), at a meeting called for the purpose of voting on each
Plan, adopted a new plan of distribution for the Class A shares of the Fund
(the Class A Plan) and approved an amended and restated plan of distribution
with respect to the Class B shares of the Fund (the Class B Plan). On May 4,
1993, the Board of Directors, including a majority of the Rule 12b-1
Directors, at a meeting called for the purpose of voting on each Plan,
approved the continuance of the Plans and Distribution Agreements and approved
 
                                     B-17
<PAGE>
 
   
modifications of the Fund's Class A and Class B Plans and Distribution
Agreements to conform them with then recent amendments to the National
Association of Securities Dealers, Inc. (NASD) maximum sales charge rule
described below. As so modified, the Class A Plan provides that (i) up to .25
of 1% of the average daily net assets of the Class A shares may be used to pay
for personal service and the maintenance of shareholder accounts (service fee)
and (ii) total distribution fees (including the service fee of .25 of 1%) may
not exceed .30 of 1%. As so modified, the Class B Plan provided that (i) up to
 .25 of 1% of the average daily net assets of the Class B shares may be paid as
a service fee and (ii) up to .75 of 1% (not including the service fee) of the
average daily net assets of the Class B shares (asset-based sales charge) may
be used as reimbursement for distribution-related expenses with respect to the
Class B shares. On May 4, 1993, the Board of Directors, including a majority
of the Rule 12b-1 Directors, at a meeting called for the purpose of voting on
each Plan, adopted a plan of distribution for the Class C shares of the Fund
and approved further amendments to the plans of distribution for the Fund's
Class A and Class B shares changing them from reimbursement type plans to
compensation type plans. The Plans were last approved by the Board of
Directors, including a majority of the Rule 12b-1 Directors, on May 29, 1997.
The Class A Plan, as amended, was approved by Class A and Class B
shareholders, and the Class B Plan, as amended, was approved by Class B
shareholders on July 19, 1994. The Class C Plan was approved by the sole
shareholder of Class C shares on August 1, 1994 and provides that (i) .25 of
1% of the average daily net assets of the Class C shares shall be paid as
compensation for providing personal service and/or maintaining shareholder
accounts and (ii) .75 of 1% of the average daily net assets of the Class C
shares shall be paid as compensation for distribution services.     
   
  CLASS A PLAN. For the fiscal year ended May 31, 1997, PSI received payments
of $100,983 under the Class A Plan. This amount was primarily expended for
payment of account servicing fees to financial advisers and other persons who
sell Class A shares. For the fiscal year ended May 31, 1997, PSI also received
approximately $107,000 in initial sales charges.     
   
  CLASS B PLAN. For the fiscal year ended May 31, 1997, the Distributor
received $1,073,611 from the Fund under the Class B Plan and spent
approximately $966,700 in distributing the Fund's Class B shares. It is
estimated that of the latter amount, approximately 2.4% ($23,200) was spent on
printing and mailing of prospectuses to other than current shareholders; 25.2%
($244,000) was spent on compensation to Pruco Securities Corporation, an
affiliated broker-dealer (Prusec), for commissions to its representatives and
other expenses, including an allocation on account of overhead and other
branch office distribution-related expenses, incurred by it for distribution
of Fund shares; and 72.4% ($699,500) on the aggregate of (i) payments of
commissions and account servicing fees to financial advisers (26.3% or
$253,800) and (ii) an allocation on account of overhead and other branch
office distribution-related expenses (46.1% or $445,700). The term "overhead
and other branch office distribution-related expenses" represents (a) the
expenses of operating Prudential Securities' branch offices in connection with
the sale of Fund shares, 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, (c) expenses of mutual fund sales coordinators to
promote the sale of Fund shares and (d) other incidental expenses relating to
branch promotion of Fund sales.     
   
  Prudential Securities also receives the proceeds of contingent deferred
sales charges paid by investors upon certain redemptions of Class B shares.
See "Shareholder Guide--How to Sell Your Shares--Contingent Deferred Sales
Charges" in the Prospectus. For the fiscal year ended May 31, 1997, the
Distributor received approximately $219,400 in contingent deferred sales
charges attributable to Class B shares.     
   
  CLASS C PLAN. For the fiscal year ended May 31, 1997, Prudential Securities
received $20,413 under the Class C Plan and spent approximately $19,700 in
distributing Class C shares. It is estimated that of the latter amount, 7.6%
or $1,500 was spent on printing and mailing to other than current
shareholders; 15.7% ($3,100) was spent on compensation to PruSec, for
commissions to its representatives and other expenses, including an allocation
on account of overhead and other branch office distribution-related expenses,
incurred by it for distribution of Fund shares; and 76.7% or $15,100 was spent
on the aggregate of (i) payments or commissions and account servicing fees to
financial advisers (53.8% or $10,600) and (ii) an allocation of overhead and
other branch office distribution-related expenses for payments of related
expenses (22.9% or $4,500). Prudential Securities also receives the proceeds
of contingent deferred sales charges paid by investors upon certain
redemptions of Class C shares. See "Shareholder Guide--How to Sell Your
Shares--Contingent Deferred Sales Charges" in the Prospectus. For the fiscal
year ended May 31, 1997, Prudential Securities received approximately $2,100
in contingent deferred sales charges attributable to Class C shares.     
 
  The Class A, Class B and Class C Plans continue in effect from year to year,
provided that each such continuance is approved at least annually by a vote of
the Board of Directors, including a majority vote of the Rule 12b-1 Directors,
cast in person at a meeting called for the purpose of voting on such
continuance. The Plans may each be terminated at any time, without penalty, by
the vote of a majority of the Rule 12b-1 Directors or by the vote of the
holders of a majority of the outstanding shares of the applicable class on not
more than 30 days' written notice to any other party to the Plans. The Plans
may not be amended to increase materially the amounts to be spent for the
services described therein without approval by the shareholders of the
applicable class (by both Class A and Class B shareholders, voting separately,
in the case of material amendments to the Class A
 
                                     B-18
<PAGE>
 
Plan), and all material amendments are required to be approved by the Board of
Directors in the manner described above. Each Plan will automatically
terminate in the event of its assignment. The Fund will not be contractually
obligated to pay expenses incurred under any Plan if it is terminated or not
continued.
 
  Pursuant to each Plan, the Board of Directors will review at least quarterly
a written report of the distribution expenses incurred on behalf of each class
of shares of the Fund by the Distributor. The report includes an itemization
of the distribution expenses and the purposes of such expenditures. In
addition, as long as the Plans remain in effect, the selection and nomination
of the Rule 12b-1 Directors shall be committed to the Rule 12b-1 Directors.
   
  Pursuant to the Distribution Agreement, the Fund has agreed to indemnify
Prudential Securities to the extent permitted by applicable law against
certain liabilities under the federal securities laws. The Distribution
Agreement was last approved by the Board of Directors, including a majority of
the Rule 12b-1 Directors, on May 29, 1997.     
 
  On October 21, 1993, PSI entered into an omnibus settlement with the SEC,
state securities regulators in 51 jurisdictions and the NASD to resolve
allegations that PSI sold interests in more than 700 limited partnerships (and
a limited number of other types of securities) from January 1, 1980 through
December 31, 1990, in violation of securities laws to persons for whom such
securities were not suitable in light of the individuals' financial condition
or investment objectives. It was also alleged that the safety, potential
returns and liquidity of the investments had been misrepresented. The limited
partnerships principally involved real estate, oil and gas producing
properties and aircraft leasing ventures. The SEC Order (i) included findings
that PSI's conduct violated the federal securities laws and that an order
issued by the SEC in 1986 requiring PSI to adopt, implement and maintain
certain supervisory procedures had not been complied with; (ii) directed PSI
to cease and desist from violating the federal securities laws and imposed a
$10 million civil penalty; and (iii) required PSI to adopt certain remedial
measures including the establishment of a Compliance Committee of its Board of
Directors. Pursuant to the terms of the SEC settlement, PSI established a
settlement fund in the amount of $330,000,000 and procedures, overseen by a
court approved Claims Administrator, to resolve legitimate claims for
compensatory damages by purchasers of the partnership interests. PSI has
agreed to provide additional funds, if necessary, for that purpose. PSI's
settlement with the state securities regulators included an agreement to pay a
penalty of $500,000 per jurisdiction. PSI consented to a censure and to the
payment of a $5,000,000 fine in settling the NASD action. In settling the
above referenced matters, PSI neither admitted nor denied the allegations
asserted against it.
 
  On January 18, 1994, PSI agreed to the entry of a Final Consent Order and a
Parallel Consent Order by the Texas Securities Commissioner. The firm also
entered into a related agreement with the Texas Securities Commissioner. The
allegations were that the firm had engaged in improper sales practices and
other improper conduct resulting in pecuniary losses and other harm to
investors residing in Texas with respect to purchases and sales of limited
partnership interests during the period of January 1, 1980 through December
31, 1990. Without admitting or denying the allegations, PSI consented to a
reprimand, agreed to cease and desist from future violations, and to provide
voluntary donations to the State of Texas in the aggregate amount of
$1,500,000. The firm agreed to suspend the creation of new customer accounts,
the general solicitation of new accounts, and the offer for sale of securities
in or from PSI's North Dallas office to new customers during a period of
twenty consecutive business days, and agreed that its other Texas offices
would be subject to the same restrictions for a period of five consecutive
business days. PSI also agreed to institute training programs for its
securities salesmen in Texas.
   
  On October 27, 1994, Prudential Securities Group, Inc. (PSG) and PSI entered
into agreements with the United States Attorney deferring prosecution
(provided PSI complies with the terms of the agreement for three years) for
any alleged criminal activity related to the sale of certain limited
partnership programs from 1983 to 1990. In connection with these agreements,
PSI agreed to add the sum of $330,000,000 to the fund established by the SEC
and executed a stipulation providing for a reversion of such funds to the
United States Postal Inspection Service. PSI further agreed to obtain a
mutually acceptable outside director to sit on the Board of Directors of PSG
and the Compliance Committee of PSI. The new director serves as an independent
"ombudsman" whom PSI employees can call anonymously with complaints about
ethics and compliance. Prudential Securities reports any allegations or
instances of criminal conduct and material improprieties to the new director.
The new director submits compliance reports which identify all such
allegations or instances of criminal conduct and material improprieties every
three months and will continue to do so for a three-year period.     
 
  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 total
gross sales of any class, all sales charges on shares of that class would be
suspended.

                     PORTFOLIO TRANSACTIONS AND BROKERAGE
 
  The Manager is responsible for decisions to buy and sell securities and
options on securities and futures for the Fund, the selection of brokers,
dealers and futures commission merchants to effect the transactions and the
negotiation of brokerage commissions, if any. For purposes of this section,
the term "Manager" includes the Subadviser. Broker-dealers may receive
brokerage commissions on Fund portfolio transactions, including options and
the purchase and sale of underlying securities upon the exercise of options.
Orders may be directed to any broker or futures commission merchant including,
to the extent and in the manner permitted by applicable law, Prudential
Securities and its affiliates. Brokerage commissions on United States
securities, options and futures exchanges or boards of trade are subject to
negotiation between the Manager and the broker or futures commission merchant.
   
  Equity securities traded in the over-the-counter market and bonds, including
convertible bonds, 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 and U.S.
Government agency securities may be purchased directly from the issuer, in
which case no commissions or discounts are paid. The Fund will not deal with
Prudential Securities in any transaction in which Prudential Securities acts
as principal. Thus, it will not deal with Prudential Securities acting as
market maker, and it will not execute a negotiated trade with Prudential
Securities if execution involves Prudential Securities acting as principal
with respect to any part of the Fund's order.     
 
  In placing orders for portfolio securities of the Fund, the Manager is
required to give primary consideration to obtaining the most favorable price
and efficient execution. Within the framework of this policy, the Manager will
consider the research and investment services provided by brokers, dealers or
futures commission merchants who effect or are parties to portfolio
transactions of the Fund, 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 the Fund may be used in managing other investment accounts.
Conversely, brokers, dealers or futures commission merchants furnishing such
services may be selected for the execution of transactions of such other
accounts, whose aggregate assets may be far larger than the Fund's, and the
services furnished by such brokers, dealers or futures commission merchants
may be used by the Manager in providing investment management for the Fund.
Commission rates are established pursuant to negotiations with the broker,
dealer or futures commission merchant based on the quality and quantity of
execution services provided by the broker, dealer, or futures commission
merchant in the light of generally prevailing rates. The policy of the Manager
is to pay higher commissions to brokers, other than Prudential Securities, for
particular transactions than might be charged if a different broker had been
selected, on occasions when, in the Manager's opinion, this policy furthers
the objective of obtaining best price and execution. In addition, the Manager
is authorized to pay higher commissions on brokerage transactions for the Fund
to brokers other than Prudential Securities in order to secure research and
investment services described above, subject to review by the Fund's Board of
Directors from time to time as to the extent and continuation of this
practice. The allocation of orders among brokers and the commission rates paid
are reviewed periodically by the Fund's Board of Directors.
 
  Portfolio securities may not be purchased from any underwriting or selling
syndicate of which Prudential Securities (or any 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. This
limitation, in the opinion of the Fund, will not significantly affect the
Fund's ability to pursue its present investment objective. However, in the
future in other circumstances, the Fund may be at a disadvantage because of
this limitation in comparison to other funds with similar objectives but not
subject to such limitations.
 
  Subject to the above considerations, Prudential Securities may act as a
securities broker or futures commission merchant for the Fund. In order for
Prudential Securities (or any affiliate) to effect any portfolio transactions
for the Fund, the commissions, fees or other remuneration received by
Prudential Securities (or any affiliate) must be reasonable and fair compared
to the commissions, fees or other remuneration paid to other brokers or
futures commission merchants in connection with comparable transactions
involving similar securities or futures contracts being purchased or sold on
an exchange or board of trade during a comparable period of time. This
standard would allow Prudential Securities (or any affiliate) to receive no
more than the remuneration which would be expected to be received by an
unaffiliated broker or futures commission merchant in a commensurate arm's-
length transaction. Furthermore, the Board of Directors of the Fund, including
a majority of the non-interested Directors, has adopted procedures which are
reasonably designed to provide that any commissions, fees or other
remuneration paid to Prudential Securities (or any affiliate) are consistent
with the foregoing standard. In accordance with Section 11(a) of the
Securities Exchange
 
                                     B-20
<PAGE>
 
Act of 1934, Prudential Securities may not retain compensation for effecting
transactions on a national securities exchange for the Fund unless the Fund
has expressly authorized the retention of such compensation. Prudential
Securities must furnish to the Fund at least annually a statement setting
forth the total amount of all compensation retained by Prudential Securities
from transactions effected for the Fund during the applicable period.
Brokerage and futures transactions with Prudential Securities (or any
affiliate) are also subject to such fiduciary standards as may be imposed upon
Prudential Securities (or such affiliate) by applicable law.
 
  Transactions in options by the Fund will be subject to limitations
established by each of the exchanges governing the maximum number of options
which may be written or held by a single investor or group of investors acting
in concert, regardless of whether the options are written or held on the same
or different exchanges or are written or held in one or more accounts or
through one or more brokers. Thus, the number of options which the Fund may
write or hold may be affected by options written or held by the Manager and
other investment advisory clients of the Manager. An exchange may order the
liquidation of positions found to be in excess of these limits, and it may
impose certain other sanctions.

by the Fund, including the amount of such commissions paid to Prudential
Securities for the three years ended May 31, 1997:

  The Fund effected approximately 0.54% of the total dollar amount of its
transactions involving the payment of commissions through Prudential
Securities during the year ended May 31, 1997. Of the total brokerage
commissions paid during that period, approximately $398,886 (or 90%) were paid
to firms which provide research, statistical or other services to PIFM. PIFM
has not separately identified a portion of such brokerage commissions as
applicable to the provision of such research, statistical or other services.
    
                    PURCHASE AND REDEMPTION OF FUND SHARES
   
  Shares of the Fund may be purchased at a price equal to the next determined
net asset value per share plus a sales charge which, at the election of the
investor, may be imposed either (i) at the time of purchase (Class A shares)
or (ii) on a deferred basis (Class B or Class C shares). Class Z shares of the
Fund are offered to a limited group of investors at net asset value without
any sales charges. See "Shareholder Guide--How to Buy Shares of the Fund" in
the Prospectus.     
   
  Each class of shares represents an interest in the same assets of the Fund
and is identical in all respects, except that (i) each class is subject to
different sales charges and distribution and/or service fees (except for Class
Z shares, which are not subject to any sales charges and distribution and/or
service fees), which may affect performance, (ii) each class has exclusive
voting rights with respect to 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
interest of any other class, (iii) each class has a different exchange
privilege, (iv) only Class B shares have a conversion feature and (v) Class Z
shares are offered exclusively for sale to a limited group of investors. See
"Distributor" and "Shareholder Investment Account--Exchange Privilege."

REDUCTION AND WAIVER OF INITIAL SALES CHARGES--CLASS A SHARES
 
  COMBINED PURCHASE AND CUMULATIVE PURCHASE PRIVILEGE. If an investor or
eligible group of related investors purchases Class A shares of the Fund
concurrently with Class A shares of other Prudential Mutual Funds, the
purchases may be combined to take advantage of the reduced sales charges
applicable to larger purchases. See the table of breakpoints under
"Shareholder Guide--Alternative Purchase Plan" in the Prospectus.
 
  An eligible group of related Fund investors includes any combination of the
following:
 
  (a) an individual;
 
  (b) the individual's spouse, their children and their parents;
 
  (c) the individual's and spouse's Individual Retirement Account (IRA);
 
  (d) any company controlled by the individual (a person, entity or group that
holds 25% or more of the outstanding voting securities of a company will be
deemed to control the company, and a partnership will be deemed to be
controlled by each of its general partners);
 
  (e) a trust created by the individual, the beneficiaries of which are the
individual, his or her spouse, parents or children;
 
  (f) a Uniform Gifts to Minors Act/Uniform Transfers to Minors Act account
created by the individual or the individual's spouse; and
 
  (g) one or more employee benefits plans of a company controlled by an
individual.
 
  In addition, an eligible group of related Fund investors may include an
employer (or group of related employers) and one or more retirement or group
plans of such employer or employers (an employer controlling, controlled by or
under common control with another employer is deemed related to that
employer).
 
  The Distributor must be notified at the time of purchase that the investor
is entitled to a reduced sales charge. The reduced sales charges will be
granted subject to confirmation of the investor's holdings. The Combined
Purchase and Cumulative Purchase Privilege does not apply to individual
participants in any retirement or group plans.
 
  RIGHTS OF ACCUMULATION. Reduced sales charges are also available through
Rights of Accumulation, under which an investor or an eligible group of
related investors, as described above under "Combined Purchase and Cumulative
Purchase Privilege," may aggregate the value of their existing holdings of
shares of the Fund and shares of other Prudential Mutual Funds (excluding
money market funds other than those acquired pursuant to the exchange
privilege) to determine the reduced sales charge. However, the value of shares
held directly with the Transfer Agent and through Prudential Securities will
not be aggregated to determine the reduced sales charge. All shares must be
held either directly with the Transfer Agent or through Prudential Securities.
The value of existing holdings for purposes of determining the reduced sales
charge is calculated using the maximum offering price (net asset value plus
maximum sales charge) as of the previous business day. See "How the Fund
Values its Shares" in the Prospectus.
 
                                     B-22
<PAGE>
 
  The Distributor must be notified at the time of purchase that the
shareholder is entitled to a reduced sales charge. The reduced sales charges
will be granted subject to confirmation of the investors' holdings. Rights of
Accumulation are not available to individual participants in any retirement or
group plans.
 
  LETTER OF INTENT. Reduced sales charges are also available to investors (or
an eligible group of related investors), including retirement and group plans,
who enter into a written Letter of Intent providing for the purchase, within a
thirteen-month period, of shares of the Fund and shares of other Prudential
Mutual Funds (Investment Letter of Intent). Retirement and group plans may
also qualify to purchase Class A shares at net asset value by entering into a
Letter of Intent whereby they agree to enroll, within a thirteen-month period,
a specified number of eligible employees or participants (Participant Letter
of Intent).
 
  For purposes of the Investment Letter of Intent, all shares of the Fund and
shares of other Prudential Mutual Funds (excluding money market funds other
than those acquired pursuant to the exchange privilege) which were previously
purchased and are still owned are also included in determining the applicable
reduction. However, the value of shares held directly with the Transfer Agent
and through Prudential Securities will not be aggregated to determine the
reduced sales charge. All shares must be held either directly with the
Transfer Agent or through Prudential Securities.
 
  A Letter of Intent permits a purchaser, in the case of an Investment Letter
of Intent, to establish a total investment goal to be achieved by any number
of investments over a thirteen-month period and, in the case of a Participant
Letter of Intent, to establish minimum eligible employee or participant goal
over a thirteen-month period. Each investment made during the period, in the
case of an Investment Letter of Intent, will receive the reduced sales charge
applicable to the amount represented by the goal, as if it were a single
investment. In the case of a Participant Letter of Intent, each investment
made during the period will be made at net asset value. Escrowed Class A
shares totaling 5% of the dollar amount of the Letter of Intent will be held
by the Transfer Agent in the name of the purchaser, except in the case of
retirement and group plans where the employer or plan sponsor will be
responsible for paying any applicable sales charge. The effective date of an
Investment Letter of Intent (except in the case of retirement and group plans)
may be back-dated up to 90 days, in order that any investments made during
this 90-day period, valued at the purchaser's cost, can be applied to the
fulfillment of the Letter of Intent goal.
 
  The Investment Letter of Intent does not obligate the investor to purchase,
nor the Fund to sell, the indicated amount. Similarly, the Participant Letter
of Intent does not obligate the retirement or group plan to enroll the
indicated number of eligible employees or participants. In the event the
Letter of Intent goal is not achieved within the thirteen-month period, the
purchaser (or the employer or plan sponsor in the case of any retirement or
group plan) is required to pay the difference between the sales charge
otherwise applicable to the purchases made during this period and sales
charges actually paid. Such payment may be made directly to the Distributor
or, if not paid, the Distributor will liquidate sufficient escrowed shares to
obtain such difference. Investors electing to purchase Class A shares of the
Fund pursuant to a Letter of Intent should carefully read such Letter of
Intent.
 
  The Distributor must be notified at the time of purchase that the investor
is entitled to a reduced sales charge. The reduced sales charge will, in the
case of an Investment Letter of Intent, be granted subject to confirmation of
the investor's holdings or in the case of a Participant Letter of Intent,
subject to confirmation of the number of eligible employees or participants in
the retirement or group plan. Letters of Intent are not available to
individual participants in any retirement or group plans.

QUANTITY DISCOUNT--CLASS B SHARES PURCHASED PRIOR TO AUGUST 1, 1994
 
  The CDSC is reduced on redemptions of Class B shares of the Fund purchased
prior to August 1, 1994 if immediately after a purchase of such shares, the
aggregate cost of all Class B shares of the Fund owned by you in a single
account exceeded $500,000. For example, if you purchased $100,000 of Class B
shares of the Fund and the following year purchased an additional $450,000 of
Class B shares with the result that the aggregate cost of your Class B shares
of the Fund following the second purchase was $550,000, the quantity discount
would be available for the second purchase of $450,000 but not for the first
purchase of $100,000. The quantity discount will be imposed at the following
rates depending on whether the aggregate value exceeded $500,000 or $1
million:

                        SHAREHOLDER INVESTMENT ACCOUNT
 
  Upon the initial purchase of Fund shares, a Shareholder Investment Account
is established for each investor under which the shares are held for the
investor by the Transfer Agent. If a stock certificate is desired, it must be
requested in writing for each transaction. Certificates are issued only for
full shares and may be redeposited in the Account at any time. There is no
charge to the investor for issuance of a certificate. The Fund makes available
to its shareholders the following privileges and plans.
 
AUTOMATIC REINVESTMENT OF DIVIDENDS AND/OR DISTRIBUTIONS
 
  For the convenience of investors, all dividends and distributions are
automatically reinvested in full and fractional shares of the Fund. An
investor may direct the Transfer Agent in writing not less than five full
business days prior to the record date to have subsequent dividends and/or
distributions sent in cash rather than reinvested. In the case of recently
purchased shares for which registration instructions have not been received on
the record date, cash payment will be made directly to the dealer. Any
shareholder who receives a cash payment representing a dividend or
distribution may reinvest such distribution at net asset value by returning
the check or the proceeds to the Transfer Agent within 30 days after the
payment date. Such investment will be made at the net asset value per share
next determined after receipt of the check or proceeds by the Transfer Agent.
Such shareholder will receive credit for any contingent deferred sales charge
paid in connection with the amount of proceeds being reinvested.
 
EXCHANGE PRIVILEGE
 
  The Fund makes available to its shareholders the privilege of exchanging
their shares of the Fund for shares of certain other Prudential Mutual Funds,
including one or more specified money market funds, subject in each case to
the minimum investment requirements of such funds. Shares of such other
Prudential Mutual Funds may also be exchanged for shares of the Fund. All
exchanges are made on the basis of relative net asset value next determined
after receipt of an order in proper form. An exchange will be treated as a
redemption and purchase for tax purposes. Shares may be exchanged for shares
of another fund only if shares of such fund may legally be sold under
applicable state laws. For retirement and group plans having a limited menu of
Prudential Mutual Funds, the Exchange Privilege is available for those funds
eligible for investment in the particular program.
 
  It is contemplated that the Exchange Privilege may be applicable to new
mutual funds whose shares may be distributed by the Distributor.
 
  CLASS A. Shareholders of the Fund may exchange their Class A shares for
Class A shares of certain other Prudential Mutual Funds, shares of Prudential
Government Securities Trust (Short-Intermediate Term Series) and shares of the
money market funds specified below. No fee or sales load will be imposed upon
the exchange. Shareholders of money market funds who acquired such shares upon
exchange of Class A shares may use the Exchange Privilege only to acquire
Class A shares of the Prudential Mutual Funds participating in the Exchange
Privilege.
 
  The following money market funds participate in the Class A Exchange
Privilege:
 
     Prudential California Municipal Fund
      (California Money Market Series)
     Prudential Government Securities Trust
      (Money Market Series)
      (U.S. Treasury Money Market Series)
     Prudential Municipal Series Fund
      (Connecticut Money Market Series)
      (Massachusetts Money Market Series)
      (New Jersey Money Market Series)
      (New York Money Market Series)
        
     Prudential MoneyMart Assets, Inc. (Class A shares)     
     Prudential Tax-Free Money Fund, Inc.
   
  CLASS B AND CLASS C. Shareholders of the Fund may exchange their Class B and
Class C shares for Class B and Class C shares, respectively, of certain other
Prudential Mutual Funds and shares of Prudential Special Money Market Fund,
Inc. No CDSC will be payable upon such exchange, but a CDSC may be payable
upon the redemption of the Class B and Class C shares acquired as a result of
an exchange. The applicable sales charge will be that imposed by the fund in
which shares were initially purchased and the purchase date will be deemed to
be the first day of the month after the initial purchase, rather than the date
of the exchange.     
 
                                     B-25
<PAGE>
 
  Class B and Class C shares of the Fund may also be exchanged for shares of
Prudential Special Money Market Fund, Inc. without imposition of any CDSC at
the time of exchange. Upon subsequent redemption from such money market fund
or after re-exchange into the Fund, such shares will be subject to the CDSC
calculated without regard to the time such shares were held in the money
market fund. In order to minimize the period of time in which shares are
subject to a CDSC, shares exchanged out of the money market fund will be
exchanged on the basis of their remaining holding periods, with the longest
remaining holding periods being transferred first. In measuring the time
period shares are held in a money market fund and "tolled" for purposes of
calculating the CDSC holding period, exchanges are deemed to have been made on
the last day of the month. Thus, if shares are exchanged into the Fund from a
money market fund during the month (and are held in the Fund at the end of
month), the entire month will be included in the CDSC holding period.
Conversely, if shares are exchanged into a money market fund prior to the last
day of the month (and are held in the money market fund on the last day of the
month), the entire month will be excluded from the CDSC holding period. For
purposes of calculating the seven year holding period applicable to the Class
B conversion feature, the time period during which Class B shares were held in
a money market fund will be excluded.
 
  At any time after acquiring shares of other funds participating in the Class
B or Class C Exchange Privilege, a shareholder may again exchange those shares
(and any reinvested dividends and distributions) for Class B or Class C shares
of the Fund, respectively, without subjecting such shares to any CDSC. Shares
of any fund participating in the Class B or Class C exchange privilege that
were acquired through reinvestment of dividends or distributions may be
exchanged for Class B or Class C shares, respectively, of other funds without
being subject to any CDSC.
          
  CLASS Z. Class Z shares may be exchanged for Class Z shares of other
Prudential Mutual Funds.     
   
  Additional details about the Exchange Privilege and prospectuses for each of
the Prudential Mutual Funds are available from the Fund's Transfer Agent,
Prudential Securities or Prusec. The Exchange Privilege may be modified,
terminated or suspended on sixty days' notice, and any fund, including the
Fund, or the Distributor, has the right to reject any exchange application
relating to such fund's shares.     
 
DOLLAR COST AVERAGING
 
  Dollar cost averaging is a method of accumulating shares by investing a
fixed amount of dollars in shares at set intervals. An investor buys more
shares when the price is low and fewer shares when the price is high. The
average cost per share is lower than it would be if a constant number of
shares were bought at set intervals.
 
  Dollar cost averaging may be used, for example, to plan for retirement, to
save for a major expenditure, such as the purchase of a home, or to finance a
college education. The cost of a year's education at a four-year college today
averages around $14,000 at a private college and around $6,000 at a public
university. Assuming these costs increase at a rate of 7% a year, as has been
projected, for the freshman class beginning in 2011, the cost of four years at
a private college could reach $210,000 and over $90,000 at a public
university./1/

AUTOMATIC SAVINGS ACCUMULATION PLAN (ASAP)
 
  Under ASAP, an investor may arrange to have a fixed amount automatically
invested in shares of the Fund monthly by authorizing his or her bank account
or Prudential Securities account (including a Command Account) to be debited
to invest specified dollar amounts in shares of the Fund. The investor's bank
must be a member of the Automatic Clearing House System. Stock certificates
are not issued to ASAP participants.
 
  Further information about this program and an application form can be
obtained from the Transfer Agent, Prudential Securities or Prusec.
 
SYSTEMATIC WITHDRAWAL PLAN
 
  A systematic withdrawal plan is available to shareholders through Prudential
Securities or the Transfer Agent. Such withdrawal plan provides for monthly or
quarterly checks in any amount, except as provided below, up to the value of
the shares in the shareholder's account. Withdrawals of Class B or Class C
shares may be subject to a CDSC. See "Shareholder Guide--How to Sell Your
Shares--Contingent Deferred Sales Charges" in the Prospectus.
 
  In the case of shares held through the Transfer Agent (i) a $10,000 minimum
account value applies, (ii) withdrawals may not be for less than $100 and
(iii) the shareholder must elect to have all dividends and/or distributions
automatically reinvested in additional full and fractional shares at net asset
value on shares held under this plan. See "Shareholder Investment Account--
Automatic Reinvestment of Dividends and/or Distributions."
 
  Prudential Securities and the Transfer Agent act as agents for the
shareholder in redeeming sufficient full and fractional shares to provide the
amount of the periodic withdrawal payment. The systematic withdrawal plan may
be terminated at any time, and the Distributor reserves the right to initiate
a fee of up to $5 per withdrawal, upon 30 days' written notice to the
shareholder.
 
  Withdrawal payments should not generally be considered as dividends, yield
or income. If periodic withdrawals continuously exceed reinvested dividends
and distributions, the shareholder's original investment will be
correspondingly reduced and ultimately exhausted.
 
  Furthermore, each withdrawal constitutes a redemption of shares, and any
gain or loss realized must generally be recognized for federal income tax
purposes. In addition, withdrawals made concurrently with the purchases of
additional shares are inadvisable because of the sales charge applicable to
(i) the purchase of Class A shares and (ii) the withdrawal of Class B and
Class C shares. Each shareholder should consult his or her own tax adviser
with regard to the tax consequences of the systematic withdrawal plan,
particularly if used in connection with a retirement plan.
 
TAX-DEFERRED RETIREMENT PLANS
 
  Various tax-deferred retirement plans, including a 401(k) plan, self-
directed individual retirement accounts and "tax-deferred accounts" under
Section 403(b)(7) of the Internal Revenue Code are available through the
Distributor. These plans are for use by both self-employed individuals and
corporate employers. These plans permit either self-direction of accounts by
participants, or a pooled account arrangement. Information regarding the
establishment of these plans, and the administration, custodial fees and other
details are available from Prudential Securities or the Transfer Agent.
 
  Investors who are considering the adoption of such a plan should consult
with their own legal counsel or tax adviser with respect to the establishment
and maintenance of any such plan.

TAX-DEFERRED RETIREMENT ACCOUNTS
 
  INDIVIDUAL RETIREMENT ACCOUNTS. An individual retirement account (IRA)
permits the deferral of federal income tax on income earned in the account
until the earnings are withdrawn. The following chart represents a comparison
of the earnings in a personal savings account with those in an IRA, assuming a
$2,000 annual contribution, an 8% rate of return and a 39.6% federal income
tax bracket and shows how much more retirement income can accumulate within an
IRA as opposed to a taxable individual savings account.

MUTUAL FUND PROGRAMS
 
  From time to time, the Fund may be included in a mutual fund program with
other Prudential Mutual Funds. Under such a program, a group of portfolios
will be selected and thereafter marketed collectively. Typically, these
programs are created with an investment theme, e.g., to seek greater
diversification, protection from interest rate movements or access to
different management styles. In the event such a program is instituted, there
may be a minimum investment requirement for the program as a whole. The Fund
may waive or reduce the minimum initial investment requirements in connection
with such a program.
   
  The mutual funds in the program may be purchased individually or as part of
a program. Since the allocation of portfolios included in the program may not
be appropriate for all investors, individuals should consult their Prudential
Securities Financial Advisor or Prudential/Pruco Securities Representative
concerning the appropriate blend of portfolios for them. If investors elect to
purchase the individual mutual funds that constitute the program in an
investment ratio different from that offered by the program, the standard
minimum investment requirements for the individual mutual funds will apply.
    
                                NET ASSET VALUE
   
  Under the Investment Company Act, the Board of Directors is responsible for
determining in good faith the fair value of securities of the Fund. In
accordance with procedures adopted by the Board of Directors, the value of
investments listed on a securities exchange and NASDAQ National Market System
securities (other than options on stock and stock indices) are valued at the
last sale price on the day of valuation or, if there was no sale on such day,
the mean between the last bid and asked prices on such day, or at the bid
price on such day in the absence of an asked price. Corporate bonds (other
than convertible debt securities) and U.S. Government securities that are
actively traded in the over-the-counter market, including listed securities
for which the primary market is believed to be over-the-counter, are valued on
the basis of valuations provided by a pricing agent or principal market maker.
Convertible debt securities that are actively traded in the over-the-counter
market, including listed securities for which the primary market is believed
to be over-the-counter, are valued at the mean between the last reported bid
and asked prices provided by principal market makers. Options on stock and
stock indices traded on an exchange are valued at the mean between the most
recently quoted bid and asked prices on the respective exchange and futures
contracts and options thereon are valued at their last sale prices as of the
close of trading on the applicable commodities exchange. Quotations of foreign
securities in a foreign currency are converted to U.S. dollar equivalents at
the current rate obtained from a recognized bank or dealer and forward
currency exchange contracts are valued at the current cost of covering or
offsetting such contracts. Should an extraordinary event, which is likely to
affect the value of the security, occur after the close of an exchange on
which a portfolio security is traded, such security will be valued at fair
value considering factors determined in good faith by the investment adviser
under procedures established by and under the general supervision of the
Fund's Board of Directors.     
 
                                     B-28
<PAGE>
 
   
  Securities or other assets for which market quotations are not readily
available, or for which the pricing agent or principal market maker does not
provide a valuation or methodology or provides a valuation or methodology
that, in the judgment of the Manager or Subadviser (or Valuation Committee or
Board of Directors), does not represent fair value, are valued by the
Valuation Committee or Board in consultation with the Manager and Subadviser.
Short-term debt securities are valued at cost, with interest accrued or
discount amortized to the date of maturity, if their original maturity was 60
days or less, unless this is determined by the Board of Directors not to
represent fair value. Short-term securities with remaining maturities of more
than 60 days, for which market quotations are readily available, are valued at
their current market quotations as supplied by an independent pricing agent or
principal market maker. The Fund will compute its net asset value at 4:15
P.M., New York time, on each day the New York Stock Exchange is open for
trading except on days on which no orders to purchase, sell or redeem Fund
shares have been received or days on which changes in the value of the Fund's
portfolio securities do not affect net asset value. In the event the New York
Stock Exchange closes early on any business day, the net asset value of the
Fund's shares shall be determined at the time between such closing and 4:15
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.     
          
  Net asset value is calculated separately for each class. The net asset value
of Class B and Class C shares will generally be lower than the net asset value
of Class A shares as a result of the larger distribution-related fee to which
Class B and Class C shares are subject and lower than the net asset value of
Class Z shares which are not subject to any distribution fee. It is expected,
however, that the net asset value per share of each class will tend to
converge immediately after the recording of dividends, if any, which will
differ by approximately the amount of the distribution and/or service fee
expense accrual differential among the classes.     
                       
                    TAXES, DIVIDENDS AND DISTRIBUTIONS     
 
  The Fund has elected to qualify and intends to remain qualified as a
regulated investment company under Subchapter M of the Internal Revenue Code.
This relieves the Fund (but not its shareholders) from paying federal income
tax on income which is distributed to shareholders, and permits net capital
gains of the Fund (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 shares in the Fund are held.
   
  Qualification as a regulated investment company requires, among other
things, that (a) at least 90% of the Fund's annual gross income (without
reduction for losses from the sale or other disposition of securities) be
derived from interest, dividends, payments with respect to securities loans,
and gains from the sale or other disposition of securities 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) the Fund derives less than 30%
of its gross income from gains (without reduction for losses) from the sale or
other disposition of securities, options thereon, futures contracts, options
thereon, forward contracts and foreign currencies held for less than three
months (except for foreign currencies directly related to the Fund's business
of investing in securities) (the short-short rule); (c) the Fund diversifies
its holdings so that, at the end of each quarter of the taxable year, (i) at
least 50% of the value of the Fund's assets is represented by cash, U.S.
Government securities and other securities limited in respect of any one
issuer to an amount not greater than 5% of the value of the assets of the Fund
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 securities); and (d) the Fund distribute to
its shareholders at least 90% of its net investment income including net
short-term capital gains other than net capital gains in each year.     
   
  The Fund is required to distribute 98% of its ordinary income in the same
calendar year in which it is earned. The Fund 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. In addition, the
Fund must distribute during the calendar year any 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 calendar year,
respectively. To the extent it does not meet these distribution requirements,
the Fund will be subject to a non-deductible 4% excise tax on the
undistributed amount. For purposes of this excise tax, income on which the
Fund pays income tax is treated as distributed.     
   
  Gains or losses on sales of securities by the Fund generally will be treated
as long-term capital gains or losses if the securities have been held by it
for more than one year, except in certain cases where the Fund acquires a put
or writes a call thereon or otherwise holds an offsetting position with
respect to the securities. Other gains or losses on the sale of securities
will be short-term capital gains or losses. Gains and losses on the sale,
lapse or other termination of options on securities will generally be treated
as gains and losses from the sale of securities. If an option written by the
Fund on securities lapses or is terminated through a closing transaction, such
as a repurchase by the Fund of the option from its holder, the Fund will
generally realize short-term capital gain or loss. If securities are sold by
the Fund pursuant to the exercise of a call option written by it, the Fund
will include the premium     
 
                                     B-29
<PAGE>
 
   
received in the sale proceeds of the securities delivered in determining the
amount of gain or loss on the sale. Certain of the Fund's transactions may be
subject to wash sale, short sale and straddle provisions of the Internal
Revenue Code which may, among other things, require the Fund to defer losses.
In addition, debt securities acquired by the Fund may be subject to original
issue discount and market discount rules, which may cause the Fund to accrue
income in advance of the receipt of cash with respect to interest or cause
gains to be treated as ordinary income.     
 
  Special rules apply to most options on stock indices, futures contracts and
options thereon and forward foreign currency exchange contracts in which the
Fund may invest. See "Investment Objective and Policies." These investments
will generally constitute Section 1256 contracts and will be required to be
"marked to market" for federal income tax purposes at the end of the Fund's
taxable year; that is, treated as having been sold at market value. Except
with respect to certain forward foreign currency exchange contracts, sixty
percent of any gain or loss recognized on such deemed sales and on actual
dispositions will be treated as long-term capital gain or loss, and the
remainder will be treated as short-term capital gain or loss.
   
  Forward currency contracts, options and futures contracts entered into by
the Fund may create "straddles" for federal income tax purposes. Positions
which are part of a straddle will be subject to certain wash sale and short
sale provisions of the Internal Revenue Code. In the case of a straddle, the
Fund may be required to defer the recognition of losses on positions it holds
to the extent of any unrecognized gain on offsetting positions held by the
Fund. Straddles may also result in the loss of the holding period of the
underlying property and, therefore, the Fund's ability to enter into forward
currency contracts, options and futures contracts may be limited by the short-
short rule.     
   
  Likewise, the Fund's ability to hold foreign currencies or engage in hedging
activities may be limited by the short-short rule.     
   
  Gains or losses attributable to fluctuations in exchange rates which occur
between the time the Fund accrues interest or other receivables or accrues
expenses or other liabilities denominated in a foreign currency and the time
the Fund actually collects such receivables or pays such liabilities are
treated as ordinary income or ordinary loss. Similarly, gains or losses on
forward foreign currency exchange contracts or dispositions of debt securities
denominated in a foreign currency attributable to fluctuations in the value of
the foreign currency between the date of acquisition of the security and the
date of disposition also are treated as ordinary gain or loss. These gains or
losses, referred to under the Internal Revenue Code as "Section 988" gains or
losses, increase or decrease the amount of the Fund's investment company
taxable income available to be distributed to its shareholders as ordinary
income, rather than increasing or decreasing the amount of the Fund's net
capital gain. If Section 988 losses exceed other investment company taxable
income during a taxable year, the Fund would not be able to make any ordinary
dividend distributions, or distributions made before the losses were realized
would be recharacterized as a return of capital to shareholders, rather than
as an ordinary dividend, reducing each shareholder's basis in his or her Fund
shares.     
 
  Shareholders electing to receive dividends and distributions in the form of
additional shares will have a cost basis for federal income tax purposes in
each share so received equal to the net asset value of a share of the Fund on
the reinvestment date.
 
  Any dividends paid shortly after a purchase by an investor may have the
effect of reducing the per share net asset value of the investor's shares by
the per share amount of the dividends. Furthermore, such dividends, although
in effect a return of capital, are subject to federal income taxes. Therefore,
prior to purchasing shares of the Fund, the investor should carefully consider
the impact of dividends, including capital gains distributions, which are
expected to be or have been announced.
 
  Any loss realized on a sale, redemption or exchange of shares of the Fund by
a shareholder will be disallowed to the extent the shares are replaced within
a 61-day period (beginning 30 days before the disposition of shares). Shares
purchased pursuant to the reinvestment of a dividend will constitute a
replacement of shares.
 
  If a shareholder who acquires shares of the Fund sells or otherwise disposes
of such shares within 90 days of acquisition, certain sales charges incurred
in acquiring such shares may not be included in the basis of such shares for
purposes of calculating gain or loss realized upon such sale or disposition.
   
  The per share dividends on Class B and Class C shares will be lower than the
per share dividends on Class A or Class Z shares as a result of the higher
distribution-related fee applicable to the Class B and Class C shares. The per
share distributions of net capital gains, if any, will be in the same amount
for Class A, Class B, Class C and Class Z shares. See "Net Asset Value."     
 
  Dividends of net investment income and distributions of net short-term
capital gains paid to a shareholder (including a shareholder acting as a
nominee or fiduciary) who is a nonresident alien individual, a foreign
corporation or a foreign partnership (foreign shareholder) are subject to a
30% (or lower treaty rate) withholding tax upon the gross amount of the
dividends unless the dividends are effectively connected with a U.S. trade or
business conducted by the foreign shareholder. Capital gain dividends paid to
a foreign shareholder generally are not subject to withholding tax. A foreign
shareholder will, however, be required to pay U.S. income tax on any dividends
and capital gain distributions which are effectively connected with a U.S.
trade or business of the foreign shareholder.
 
                                     B-30
<PAGE>
 
   
  Dividends received by Corporate shareholders from the Fund are eligible for
a dividends-received deduction of 70% to the extent the Fund's income is
derived from qualified dividends received by the Fund from domestic
corporations. Since the Fund is likely to have a substantial portion of its
assets invested in securities of foreign issuers, the amount of the Fund's
dividends eligible for the corporate dividends received deduction will be
minimal.     
 
  Income received by the Fund from sources within foreign countries may be
subject to withholding and other taxes imposed by such countries. Income tax
treaties between certain countries and the United States may reduce or
eliminate such taxes. It is impossible to determine in advance the effective
rate of foreign tax to which the Fund will be subject, since the amount of the
Fund's assets to be invested in various countries is not known.
   
  If the Fund is liable for foreign income taxes, and if more than 50% of the
value of the Fund's assets consists of securities of foreign corporations, the
Fund may elect to "pass through" to the Fund's shareholders the amount of
foreign income taxes paid by the Fund, but there can be no assurance that the
Fund will be able to do so. For the fiscal year ended May 31, 1997, the Fund
did not elect under the Internal Revenue Code to "pass through" to its
shareholders foreign income taxes paid by the Fund, since at the close of its
taxable year less than 50% of the value of the Fund's total assets consisted
of securities of foreign corporations. If the Fund does elect to "pass
through" the foreign taxes paid, shareholders will be required to (i) include
in gross income (in addition to taxable dividends actually received) their pro
rata share of the foreign income taxes paid by the Fund; and (ii) treat their
pro rata share of foreign income taxes as paid by them. Shareholders will then
be permitted either to deduct their pro rata share of foreign income taxes in
computing their taxable income or to claim a foreign tax credit against U.S.
income taxes. No deduction for foreign taxes may be claimed by a shareholder
who does not itemize deductions. Foreign shareholders may not deduct or claim
a credit for foreign tax unless the dividends paid to them by the Fund are
effectively connected with a U.S. trade or business. Accordingly, a foreign
shareholder may recognize additional taxable income as a result of the Fund's
election to pass through the foreign taxes to shareholders.     
   
  The amount of foreign taxes for which a shareholder may claim a credit in
any year will generally be subject to a separate limitation for "passive
income," which includes, among other things, dividends, interest and certain
foreign currency gains. Gain from the sale of a security and gain or loss from
a Section 988 transaction which is treated as ordinary income or loss (or
would have been so treated absent an election by the Fund) will be treated as
derived from sources within the United States, potentially reducing the amount
allowable as a credit under the limitation.     
 
  Each shareholder will be notified within 60 days after the close of the
Fund's taxable year whether the foreign taxes paid by the Fund will "pass
through" for that year and, if so, such notification will designate (a) the
shareholder's portion of the foreign taxes paid by the Fund and (b) the
portion of the dividend which represents income derived from foreign sources.
 
  The tax consequences to a foreign shareholder entitled to claim the benefits
of an applicable tax treaty may be different from those described herein.
Foreign shareholders are advised to consult their own tax advisers with
respect to the particular tax consequences to them of an investment in the
Fund.
       
                            PERFORMANCE INFORMATION
   
  AVERAGE ANNUAL TOTAL RETURN. The Fund may from time to time advertise its
average annual total return. Average annual total return is determined
separately for Class A, Class B, Class C and Class Z shares. See "How the Fund
Calculates Performance" in the Prospectus.     
 
  Average annual total return is computed according to the following formula:
 
                        P(1+T)/to the nth power/ = ERV
 
Where: P = a hypothetical initial payment of $1,000.
   T = average annual total return.
   n = number of years.
   ERV = Ending Redeemable Value at the end of the 1, 5 or 10 year periods
       (or fractional portion thereof) of a hypothetical $1,000 payment made
       at the beginning of the 1, 5 or 10 year periods.
 
  Average annual total return takes into account any applicable initial or
contingent deferred sales charges but does not take into account any federal
or state income taxes that may be payable upon redemption.
 
                                     B-31
<PAGE>
 
   
  The average annual total returns for Class A shares for the one year, five
year and since inception (January 22, 1990) periods ended May 31, 1997 were
 .10%, 12.86% and 8.19%, respectively. The average annual total returns for
Class B shares for the one year, five year and since inception (September 28,
1987) periods ended May 31, 1997 were (.49)%, 13.01% and 7.48%, respectively.
Without the expense subsidy the average annual total return with respect to
the Class B shares of the Fund for the since inception period would have been
7.47%. The average annual total returns for Class C shares for one year and
since inception (August 1, 1994) periods ended May 31, 1997 were 3.51% and
14.93%, respectively.     
   
  AGGREGATE TOTAL RETURN. The Fund may also advertise its aggregate total
return. Aggregate total return is determined separately for Class A, Class B,
Class C and Class Z shares. See "How the Fund Calculates Performance" in the
Prospectus.     
 
  Aggregate total return represents the cumulative change in the value of an
investment in the Fund and is computed according to the following formula:
 
                                    ERV--P
                                    ------
                                       P
 
Where:
   P =
     a hypothetical initial payment of $1,000.
   ERV =
      Ending Redeemable Value at the end of the 1, 5 or 10 year periods (or
      fractional portion thereof) of a hypothetical $1,000 payment made at
      the beginning of the 1, 5 or 10 year periods.
 
  Aggregate total return does not take into account any federal or state
income taxes that may be payable upon redemption or any applicable initial or
contingent deferred sales charges.
   
  The aggregate total returns for Class A shares for the one year, five year
and since inception (January 21, 1990) periods ended May 31, 1997 were 5.37%,
92.77% and 87.80%, respectively. The aggregate total returns for Class B
shares for the one year, five year and since inception (September 28, 1987)
periods ended May 31, 1997 were 4.51%, 85.40% and 100.90%, respectively.
Without the expense subsidiary the aggregate total return for the Class B
shares for the since inception period would have been 100.64%. The aggregate
total return for Class C shares for the one year and since inception (August
1, 1994) periods ended May 31, 1997 were 4.51% and 48.23%, respectively. The
aggregate total return for the Class Z shares for the since inception
(September 16, 1996) period ended May 31, 1997 was 7.17%.     
   
  YIELD. The Fund may from time to time advertise its yield as calculated over
a 30-day period. Yield is calculated separately for Class A, Class B, Class C
and Class Z shares. This yield will be computed by dividing the Fund's net
investment income per share earned during this 30-day period by the maximum
offering price per share on the last day of this period. Yield is calculated
according to the following formula:     
 
                                      a--b
                          YIELD = 2[(------- +1)/to the 6th power/ -1]
                                       cd
 
Where:
     a = dividends and interest earned during the period.
     b = expenses accrued for the period (net of reimbursements).
     c = the average daily number of shares outstanding during the period
     that were entitled to receive dividends.
     d = the maximum offering price per share on the last day of the
     period.
 
  Yield fluctuates and an annualized yield quotation is not a representation
by the Fund as to what an investment in the Fund will actually yield for any
given period.

Notes to Financial Statements                             RESOURCES FUND, INC.
- --------------------------------------------------------------------------------
Prudential Natural Resources Fund, Inc., (the 'Fund'), is registered under the
Investment Company Act of 1940 as a diversified, open-end management investment
company. The Fund's investment objective is long-term growth of capital which it
seeks to achieve by investing primarily in equity securities of foreign and
domestic natural resource companies.
- ------------------------------------------------------------
Note 1. Accounting Policies

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

Security Valuation: Securities traded on an exchange are valued at the last
reported sales price on the primary exchange on which they are traded.
Securities traded in the over-the-counter market (including securities listed on
exchanges for which a last sales price is not available) are valued at the
average of the last reported bid and asked prices. Securities for which market
quotations are not available, other than private placements, shall each be
valued at a price supplied by an independent pricing agent, which is, in the
opinion of such pricing agent, representative of the market value of such
securities as of the time of determination of net asset value. Securities for
which market quotations are not readily available, and for which the pricing
agent or principal market maker does not provide a valuation, including
restricted securities, will be valued at fair value as determined in good faith
according to a pricing procedure developed by the Investment Adviser under
procedures established by and under the general supervision of the Fund's Board
of Directors. Options listed on exchanges are valued at their closing price on
the applicable exchange.

Short-term securities which mature in more than 60 days are valued at current
market quotations. Short-term securities which mature in 60 days or less are
valued at amortized cost which approximates market value.

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 exceeds
the principal amount of the repurchase transaction including accrued interest.
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.

Foreign Currency Translation: The books and records of the Fund are maintained
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars on
the following basis:

(i) market value of investment securities, other assets and liabilities--at the
daily closing rates of exchange.

(ii) purchases and sales of investment securities, income and expenses--at the
rate of exchange prevailing on the respective dates of such transactions.

Although the net assets of the Fund are presented using the foreign exchange
rates and market values at the close of the fiscal year, the Fund does not
isolate that portion of the results of operations arising as a result of changes
in the foreign exchange rates from the fluctuations arising from changes in the
market prices of securities held at the fiscal year end. Similarly, the Fund
does not isolate the effect of changes in foreign exchange rates from the
fluctuations arising from changes in the market prices of long-term portfolio
securities sold during the fiscal year.

Net realized gains on foreign currency transactions represents net foreign
exchange gains or losses from disposition of foreign currencies, currency gains
or losses realized between the trade and settlement dates on security
transactions, and the difference between the amounts of dividends, interest and
foreign taxes recorded on the Fund's books and the U.S. dollar equivalent
amounts actually received or paid. Net unrealized currency gains and losses from
valuing foreign currency denominated assets and liabilities (other than
investments) at fiscal year end exchange rates are reflected as a component of
net unrealized appreciation on foreign currencies.

Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and the regulation of foreign securities
markets.

The Fund, as writer of an option, has no control over whether the underlying
securities or currencies may be sold (called) or purchased (put). As a result,
the Fund bears the market risk of an unfavorable change in the price of the
security or currency underlying the written option. The Fund, as purchaser of an
option, bears the risk of the potential inability of the counterparties to meet
the terms of their contracts.

Securities Transactions and Investment Income: Securities transactions are
recorded on the trade date. Realized gains and losses from investment and

Notes to Financial Statements                             RESOURCES FUND, INC.
- --------------------------------------------------------------------------------
currency transactions are calculated on the identified cost basis. Dividend
income is recorded on the ex-dividend date and interest income is recorded on an
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 of the Fund based
upon the relative proportion of net assets of each class at the beginning of the
day.

Taxes: It is the Fund's policy to continue to meet the requirements of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to shareholders. Therefore, no federal
income tax provision is required.

Withholding taxes on foreign interest and dividends have been provided for in
accordance with the Fund's understanding of the applicable country's tax rules
and rates.

Dividends and Distributions: The Fund expects to pay dividends out of net
investment income and make distributions of any net capital gains, at least
annually. Dividends and distributions are recorded on the ex-dividend date.

Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles. These differences are primarily due to differing treatments of wash
sales, foreign currencies and passive investment companies' transactions.

Equalization: Effective June 1, 1996, the Fund discontinued the accounting
practice of equalization. Equalization is a practice whereby a portion of the
proceeds from sales and costs of repurchases of capital shares, equivalent on a
per share basis to the amount of distributable net investment income on the date
of the transaction, is credited or charged to undistributed net investment
income. The balance of $39,777 of undistributed net investment income at May 31,
1996, resulting from equalization was transferred to paid-in capital in excess
of par. Such reclassification has no effect on net assets, results of
operations, or net asset value per share.

Reclassification of Capital Accounts: The Fund accounts and reports for
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants', Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income; Capital Gain, and
Return of Capital Distributions by Investment Companies. The effect of applying
this statement was to decrease accumulated net investment loss and decrease
accumulated net realized gain on investments by $1,365,054 for foreign currency
gains realized and tax-basis net operating losses during the fiscal year ended
May 31, 1997.
- ------------------------------------------------------------
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'); PIC furnishes investment advisory services in
connection with the management of the Fund. PIFM pays for the services of PIC,
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 .75 of 1% of the Fund's average daily net assets.

The Fund has a distribution agreement with Prudential Securities Incorporated
('PSI'), which acts as the distributor of the Class A, Class B, Class C and
Class Z shares of the Fund. The Fund compensates PSI for distributing and
servicing the Fund's Class A, Class B and Class C shares, pursuant to plans of
distribution, (the 'Class A, B and C Plans') regardless of expenses actually
incurred by them. The distribution fees are accrued daily and payable monthly.
No distribution or service fees are paid to PSI as distributor of the Class Z
shares of the Fund.

Pursuant to the Class A, B and C Plans, the Fund compensates PSI for its
distribution-related activities at an annual rate of up to .30 of 1%, 1% and 1%
of the average daily net assets of the Class A, B and Class C shares,
respectively. Such expenses under the Plans were .25 of 1%, 1% and 1% of the
average daily net assets of the Class A, B and C shares, respectively, for the
year ended May 31, 1997.

PSI has advised the Fund that it has received approximately $107,000 in
front-end sales charges resulting from sales of Class A shares during the year
ended May 31, 1997. From these fees, PSI paid such sales charges to dealers
which in turn paid commissions to salespersons and incurred other distribution
costs.

PSI has advised the Fund that for the year ended May 31, 1997, it received
approximately $219,400 and $2,100 in contingent deferred sales

- --------------------------------------------------------------------------------
charges imposed upon certain redemptions by Class B and Class C shareholders,
respectively.

PSI, PIFM and PIC are indirect, wholly-owned subsidiaries of The Prudential
Insurance Company of America.

The Fund, along with other affiliated registered investment companies (the
'Funds'), entered into a credit agreement (the 'Agreement') on December 31, 1996
with an unaffiliated lender. The maximum commitment under the Agreement is
$200,000,000. The Agreement expires on December 30, 1997. Interest on any such
borrowings outstanding will be at market rates. The purpose of the Agreement is
to serve as an alternative source of funding for capital share redemptions. The
Fund has not borrowed any amounts pursuant to the Agreement as of May 31, 1997.
The Funds pay a commitment fee at an annual rate of .055 of 1% on the unused
portion of the credit facility. The commitment fee is accrued and paid quarterly
on a pro-rata basis by the Funds.
- ------------------------------------------------------------
Note 3. Other Transactions With Affiliates

Prudential Mutual Fund Services LLC ('PMFS'), a wholly-owned subsidiary of PIMF,
serves as the Fund's transfer agent and during the year ended May 31, 1997, the
Fund incurred fees of approximately $200,000 for the services of PMFS. As of May
31, 1997, approximately $19,000 of such fees were due to PMFS. Transfer agent
fees and expenses in the Statement of Operations include certain-out-of pocket
expenses paid to non-affiliates.

For the year ended May 31, 1997, PSI and/or its foreign affiliates earned
approximately $8,100 in brokerage commissions from portfolio transactions
executed on behalf of the Fund.
- ------------------------------------------------------------
Note 4. Portfolio Securities

Purchases and sales of investment securities, other than short-term investments
for the year ended May 31, 1997 aggregated $84,531,466 and $77,965,627,
respectively.

The federal income tax basis of the Fund's investments at May 31, 1997 was
$134,413,278 and accordingly, net unrealized appreciation for federal income tax
purposes was $22,852,235 (gross unrealized appreciation--$29,292,258 gross
unrealized depreciation--$6,440,023).

For federal income tax purposes the Fund will elect to treat net currency losses
of approximately $31,000 incurred in the seven month period ended May 31, 1997
as having been incurred in the following fiscal year.
- ------------------------------------------------------------
Note 5. Capital

The Fund offers Class A, Class B, Class C and Class Z shares. Class A shares are
sold with a front-end sales charge of up to 5%. Class B shares are sold with a
contingent deferred sales charge which declines from 5% to zero depending on the
period of time the shares are held. Class C shares are sold with a contingent
deferred sales charge of 1% during the first year. Class B shares will
automatically convert to Class A shares on a quarterly basis approximately seven
years after purchase. Special exchange privileges are also available for
shareholders who qualify to purchase Class A shares at net asset value. Class Z
shares are not subject to any sales or redemption charge and are offered
exclusively for sale to a limited group of investors.

The Fund has authorized 500 million shares of common stock $.01 par value per
share equally divided into four classes, designated Class A, Class B, Class C
and Class Z common stock.

Report of Independent Accountants                         RESOURCES FUND, INC.
- --------------------------------------------------------------------------------
To the Board of Directors and Shareholders of
Prudential Natural Resources Fund, Inc.

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Prudential Natural Resources Fund,
Inc. (the 'Fund') at May 31, 1997, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
'financial statements') are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at May 31,
1997 by correspondence with the custodian, provide a reasonable basis for the
opinion expressed above.

                        DESCRIPTION OF SECURITY RATINGS
   
MOODY'S INVESTORS SERVICE, INC.     
 
  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 risk appear somewhat larger than the Aaa
securities.
   
  A: Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper-medium-grade obligations. Factors giving
security to principal and interest are considered adequate, but elements may
be present which suggest a susceptibility to impairment sometime in the
future.     
 
  Baa: Bonds which are rated Baa are considered as medium grade obligations,
(i.e., they are neither highly protected nor poorly secured.) Interest
payments and principal security appear adequate for the present, but certain
protective elements may be lacking or may be characteristically unreliable
over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
  Moody's applies numerical modifiers 1, 2 and 3 in each generic rating
classification from Aa to B. The modifier 1 indicates that the company ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and the modifier 3 indicates that the company ranks in the
lower end of its generic rating category.
 
SHORT-TERM DEBT RATINGS
 
  Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations. These obligations have an original
maturity not exceeding one year, unless explicitly noted.
   
  Prime-1: Issues rated "Prime-1" (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations.     
   
  Prime-2: Issues rated "Prime-2" (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations.     
 
STANDARD & POOR'S RATINGS GROUP
 
DEBT 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.
 
  A: Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher-rated categories.
 
  BBB: Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher-rated categories.
 
COMMERCIAL PAPER RATINGS
 
  S&P's commercial paper ratings are current assessments 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. Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation.     
   
  A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high for issues
designated A-1.

                APPENDIX I--GENERAL INVESTMENT INFORMATION     
 
ASSET ALLOCATION
   
  Asset allocation is a technique for reducing risk and 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
rate 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.

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 below 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 1996. 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 the Fund or of
any sector in which the Fund 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 "Fund Expenses" in the 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.

INFORMATION ABOUT THE PRUDENTIAL MUTUAL FUNDS
   
  As of June 30, 1997 Prudential Investments Fund Management is the fifteenth
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

  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.

    subject to change.

    Prudential Mutual Funds for which PIC serves as the subadviser, portfolios

    year ended December 31, 1995.

  None.
 
ITEM 26. NUMBER OF HOLDERS OF SECURITIES.
   
  As of July 11, 1997 there were 6,322, 13,627, 306 and 208 record holders of
Class A, Class B, Class C and Class Z shares, respectively, of common stock,
$.01 par value per share, of the Registrant.     
 
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 VI of the Fund's By-
Laws (Exhibit 2 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
Agreement (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 Agreement (Exhibit 5(a) 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 Agreement 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.

             PRUDENTIAL-BACHE GLOBAL NATURAL RESOURCES FUND, INC.

                              Management Agreement
                              --------------------

         Agreement, made this 1st day of March 1988 between Prudential-Bache
Global Natural Resources Fund, Inc., a Maryland corporation (the "Fund"), and
Prudential Mutual Fund Management, Inc., a Delaware corporation (the "Manager").

                              W I T N E S S E T H
         WHEREAS, the Fund is a diversified, open-end management investment
company registered under the Investment Company Act of 1940, as amended (the
1940 Act); and

         WHEREAS, the Fund desires to retain the Manager to render or contract
to obtain as hereinafter provided investment advisory services to the Fund and
the Fund also desires to avail itself of the facilities available to the Manager
with respect to the administration of its day to day corporate affairs, and the
Manager is willing to render such investment advisory and administrative
services;

         NOW, THEREFORE, the parties agree as follows:

         1.  The Fund hereby appoints the Manager to act as manager of the Fund
and administrator of its corporate affairs for the period and on the terms set
forth in this Agreement.  The Manager accepts such appointment and agrees to
render the services herein described, for the compensation herein provided.  The
Manager will enter into an agreement, dated the date hereof, with The Prudential
Investment Corporation ("PIC") pursuant to which PIC shall furnish to the Fund
the investment advisory services specified therein in connection with the
management of the Fund.  Such agreement in the
<PAGE>
 
form attached as Exhibit A is hereinafter referred to as "the Subadvisory
Agreement". The Manager will continue to have responsibility for all investment
advisory services furnished pursuant to the Subadvisory Agreement.

         2.  Subject to the supervision of the Board of Directors of the Fund,
the Manager shall administer the Fund's corporate affairs and, in connection
therewith, shall furnish the Fund with office facilities and with clerical,
bookkeeping and recordkeeping services at such office facilities and, subject to
Section 1 hereof and the Subadvisory Agreement, the Manager shall manage the
investment operations of the Fund and the composition of the Fund's portfolio,
including the purchase, retention and disposition thereof, in accordance with
the Fund's investment objectives, policies and restrictions as stated in the
Prospectus (hereinafter defined) and subject to the following understandings:

    (a)  The Manager shall provide supervision of the Fund's investments and
determine from time to time what investments or securities will be purchased,
retained, sold or loaned by the Fund, and what portion of the assets will be
invested or held uninvested as cash.

    (b)  The Manager, in the performance of its duties and obligations under
this Agreement, shall act in conformity with the Articles of Incorporation, By-
Laws and Prospectus (hereinafter defined) of the Fund and with the instructions
and directions of the Board of Directors of the Fund and will conform to and
comply with the requirements of the 1940 Act and

                                       2
<PAGE>
 
all other applicable federal and state laws and regulations.

    (c)  The Manager shall determine the securities and futures contracts to be
purchased or sold by the Fund and will place orders pursuant to its
determinations with or through such persons, brokers, dealers or futures
commission merchants (including but not limited to Prudential-Bache Securities
Inc.) in conformity with the policy with respect to brokerage as set forth in
the Fund's Registration Statement and Prospectus (hereinafter defined) or as the
Board of Directors may direct from time to time.  In providing the Fund with
investment supervision, it is recognized that the Manager will give primary
consideration to securing the most favorable price and efficient execution.
Consistent with this policy, the Manager may consider the financial
responsibility, research and investment information and other services provided
by brokers, dealers or futures commission merchants who may effect or be a party
to any such transaction or other transactions to which other clients of the
Manager may be a party.  It is understood that Prudential-Bache Securities Inc.
may be used as principal broker for securities transactions but that no formula
has been adopted for allocation of the Fund's investment transaction business.
It is also understood that it is desirable for the Fund that the Manager have
access to supplemental investment and market research and security and economic
analysis provided by brokers or futures commission merchants and that such
brokers may execute brokerage transactions at a higher cost to

                                       3
<PAGE>
 
the Fund than may result when allocating brokerage to other brokers or futures
commission merchants on the basis of seeking the most favorable price and
efficient execution. Therefore, the Manager is authorized to pay higher
brokerage commissions for the purchase and sale of securities and futures
contracts for the Fund to brokers or futures commission merchants who provide
such research and analysis, subject to review by the Fund's Board of Directors
from time to time with respect to the extent and continuation of this practice.
It is understood that the services provided by such broker or futures commission
merchant may be useful to the Manager in connection with its services to other
clients.

    On occasions when the Manager deems the purchase or sale of a security or a
futures contract to be in the best interest of the Fund as well as other clients
of the Manager or the Subadviser, the Manager, to the extent permitted by
applicable laws and regulations, may, but shall be under no obligation to,
aggregate the securities or futures contracts to be so sold or purchased in
order to obtain the most favorable price or lower brokerage commissions and
efficient execution.  In such event, allocation of the securities or futures
contracts so purchased or sold, as well as the expenses incurred in the
transaction, will be made by the Manager in the manner it considers to be the
most equitable and consistent with its fiduciary obligations to the Fund and to
such other clients.

    (d)  The Manager shall maintain all books and records with

                                       4
<PAGE>
 
respect to the Fund's portfolio transactions and shall render to the Fund's
Board of Directors such periodic and special reports as the Board may reasonably
request.

    (e)  The Manager shall be responsible for the financial and accounting
records to be maintained by the Fund (including those being maintained by the
Fund's Custodian).
    (f)  The Manager shall provide the Fund's Custodian on each business day
with information relating to all transactions concerning the Fund's assets.

    (g)  The investment management services of the Manager to the Fund under
this Agreement are not to be deemed exclusive, and the Manager shall be free to
render similar services to others.

         3.  The Fund has delivered to the Manager copies of each of the
following documents and will deliver to it all future amendments and
supplements, if any:

    (a)  Articles of Incorporation of the Fund, as filed with the Secretary of
State of Maryland (such Articles of Incorporation, as in effect on the date
hereof and as amended from time to time, are herein called the "Articles of
Incorporation");

    (b)  By-Laws of the Fund (such By-Laws, as in effect on the date hereof and
as amended from time to time, are herein called the "By-Laws");
    (c)  Certified resolutions of the Board of Directors of the Fund authorizing
the appointment of the Manager and

                                       5

Information, as currently in effect and as amended or supplemented from time to
time, being herein called the "Prospectus").

         4.  The Manager shall authorize and permit any of its directors,
officers and employees who may be elected as directors or officers of the Fund
to serve in the capacities in which they are elected. All services to be
furnished by the Manager under this Agreement may be furnished through the
medium of any such directors, officers or employees of the Manager.

         5. The Manager shall keep the Fund's books and records required to be
maintained by it pursuant to paragraph 2 hereof.  The Manager agrees that all
records which it maintains for the Fund are the property of the Fund and it will
surrender promptly to the Fund any such records upon the Fund's request,
provided however that the Manager may retain a copy of such records.  The
Manager further agrees to preserve for the periods prescribed by Rule 31a-2

                                       6

Manager pursuant to Paragraph 2 hereof.

              PRUDENTIAL-BACHE GLOBAL NATURAL RESOURCES FUND, INC.

                             Subadvisory Agreement



     Agreement made as of this 1st day of March, 1988 between Prudential Mutual
Fund Management Inc., a Delaware Corporation ("PMF" or the "Manager"), and The
Prudential Investment Corporation, a New Jersey Corporation (the "Subadviser").

     WHEREAS, the Manager has entered into a Management Agreement, dated March
1, 1988(the "Management Agreement"), with Prudential-Bache Global Natural
Resources Fund, Inc. (the "Fund"), a Maryland corporation and a diversified
open-end management investment company registered under the Investment Company

Fund.

     WHEREAS, PMF desires to retain the Subadviser to provide investment
advisory services to the Fund in connection with the management of the Fund and
the Subadviser is willing to render such investment advisory services.

     NOW, THEREFORE, the Parties agree as follows:

1.  (a) Subject to the supervision of the Manager and of the Board of Directors
of the Fund, the Subadviser shall manage the investment operations of the Fund
and the composition of the Fund's portfolio, including the purchase, retention
and disposition thereof, in accordance with the Fund's investment objectives,
policies and restrictions as stated in the Prospectus (such Prospectus and
Statement of Additional Information as currently in effect and as amended or
supplemented from time to time, being herein called the "Prospectus"), and
subject to the following understandings:

          (i)   The Subadviser shall provide supervision of the Fund's
investments and determine from time to time what investments and securities will
be purchased, retained, sold or loaned by the Fund, and what portion of the
assets will be invested or held uninvested as cash.

          (ii)  In the performance of its duties and obligations under this
Agreement, the Subadviser shall act in conformity with the Articles of
Incorporation, By-Laws and Prospectus of the Fund and with the instructions and
directions of the Manager and of the Board of Directors of the Fund and will

<PAGE>
 
          (iii)  The Subadviser shall determine the securities  to be purchased
or sold by the Fund and will place orders with or through such persons, brokers,
dealers or  futures commission merchants  (including but not limited to
Prudential-Bache Securities Inc.) to carry out the policy with respect to
brokerage as set forth in the Fund's Registration Statement and Prospectus or as
the Board of Directors may direct from time to time.  In providing the Fund with
investment supervision, it is recognized that the Subadviser will give primary
consideration to securing the most favorable price and efficient execution.
Within the framework of this policy, the Subadviser may consider the financial
responsibility, research and investment information and other services provided
by brokers, dealers or futures commission merchants who may effect or be a party
to any such transaction or other transactions to which the Subadviser's other
clients may be a party.  It is understood that Prudential-Bache Securities Inc.
may be used as principal broker for securities transactions but that no formula
has been adopted for allocation of the Fund's investment transaction business.
It is also understood that it is desirable for the Fund that the Subadviser have
access to supplemental investment and market research and security and economic
analysis provided by brokers or futures commission merchants who may execute
brokerage transactions at a higher cost to the Fund than may result when
allocating brokerage to other brokers on the basis of seeking the most favorable
price and efficient execution.  Therefore, the Subadviser is authorized to place
orders for the purchase and sale of securities and futures contracts for the
Fund with such brokers or future commission merchants, subject to review by the
Fund's Board of Directors from time to time with respect to the extent and
continuation of this practice.  It is understood that the services provided by

aggregate the securities or futures contract to be sold or purchased in order to
obtain the most favorable price or lower brokerage commissions and efficient
execution.  In such event, allocation of the securities or futures contract so
purchased or sold, as well as the expenses incurred

     property of the Fund and the Subadviser will surrender promptly to the Fund
     any of such records upon the Fund's request, provided however that the

     agrees to preserve for the periods prescribed by Rule 31a-2 of the
     Commission under the 1940 Act any such records as are required to be
     maintained by it pursuant to paragraph 1(a) hereof.

duties or from its reckless disregard of its obligations and duties under this

officer or employee of the Fund to engage in any other business or to devote his
or her time and attention in part to the management or other aspects of any
business, whether of a similar or a dissimilar nature, nor limit or restrict the
Subadviser's right to engage in any other business or to render services of any
kind to any other corporation, firm, individual or association.

7.    During the term of this Agreement, the Manager agrees to furnish the
Subadviser at its principal office all prospectuses, proxy statements, reports
to stockholders, sales literature or other material prepared for distribution to
stockholders of the Fund or the public, which refer to the Subadviser in any
way, prior to use thereof and not to use material if the Subadviser reasonably

agreed) after receipt thereof.  Sales literature may be furnished to the
Subadviser hereunder by first-class or overnight mail, facsimile transmission

Such information shall be similar in kind and scope to that furnished to the
Fund in connection with the initial approval of this Contract. In addition, the
Custodian will promptly inform the Fund in the event that the Custodian learns
of a material adverse change in the financial condition of a foreign sub-
custodian or is notified by a foreign banking institution employed as a foreign
sub-custodian that there appears to be a substantial likelihood that its
shareholders' equity will decline below $200 million (U.S. dollars or the
equivalent thereof) or that its shareholders' equity has declined below $200
million (in each case computed in accordance with generally accepted U.S.
accounting principles).

       3.11  Branches of U.S. Banks.
             -----------------------

             (a)  Except as otherwise set forth in this Contract, the provisions
hereof shall not apply where the custody of the Fund assets maintained in a
foreign branch of a banking institution which is a "bank" as defined by Section
2(a)(5) of the Investment Company Act of 1940 which meets the qualification set
forth in Section 26(a) of said Act. The appointment of any such branch as a sub-
custodian shall be governed by Article 1 of this Contract.

4.  Payments for Repurchases or Redemptions and Sales of Shares of the Fund
    -----------------------------------------------------------------------

     From such funds as may be available for the purpose but subject to the
limitations of the Articles of Incorporation and any applicable votes of the
Board of Directors of the Fund pursuant thereto, the Custodian shall, upon
receipt of instructions from the Transfer Agent, make funds available for
payment to holders of Shares who have delivered to the Transfer Agent a request
for redemption or repurchase of their Shares.  In connection with the redemption
or repurchase of Shares of the Fund, the Custodian is authorized upon receipt of
instructions from the Transfer Agent to wire funds to or through a commercial
bank designated by the redeeming shareholders.  In connection with 

                                     -20-

the redemption or repurchase of Shares of the Fund, the Custodian shall honor
checks drawn on the Custodian by a holder of Shares, which checks have been
furnished by the Fund to the holder of Shares, when presented to the Custodian
in accordance with such procedures and controls as are mutually agreed upon from
time to time between the Fund and the Custodian.

     The Custodian shall receive from the distributor for the Fund's Shares  or
from the Transfer Agent of the Fund and deposit into the Fund's account such
payments as are received for Shares of the Fund issued or sold from time to time
by the Fund.  The Custodian will provide timely notification to the Fund and the
Transfer Agent of any receipt by it of payments for Shares of the Fund.

5.  Proper Instructions

     Proper Instructions as used herein means a writing signed or initialled by
one or more person or persons as the Board of Directors shall have from time to
time authorized.  Each such writing shall set forth the specific transaction or
type of transaction involved, including a specific statement of the purpose for
which such action is requested.  Oral instructions will be considered Proper
Instructions if the Custodian reasonably believes them to have been given by a
person authorized to give such instructions with respect to the transaction
involved.  The Fund shall cause all oral instructions to be confirmed in
writing.  It is understood and agreed that the Board of Directors has authorized
(i) The Prudential Insurance Company of America ("Prudential"),  as investment

to matters set forth in Section 2.2 (13), Section 2.7 (3), Section 2.7(4) and
Section 2.7 (5). The Custodian may rely upon the certificate of an officer of
Prudential or PMF as the case may be, with respect to the person or persons
authorized on behalf of Prudential and PMF, respectively, to sign, initial or
give proper instructions for the purposes of Article 2 or Article 3. Upon
receipt of a certificate of the Secretary or an Assistant Secretary as to the
authorization by the Board of Directors of the Fund accompanied by a detailed
description of procedures approved by the Board of Directors, Proper
Instructions may include communications effected directly between electro-
mechanical or electronic devices provided that the Board of Directors and the
Custodian are satisfied that such procedures afford adequate safeguards for the
Fund's assets.

6.   Actions Permitted without Express Authority
     -------------------------------------------

     The Custodian may in its discretion, without express authority from the
Fund:

        (1)  make payments to itself or others for minor expenses of handling
securities or other similar items relating to its duties under this Contract,
provided that all such payments shall be accounted for to the Fund;

     The Custodian shall be protected in acting upon any instructions, notice,
request, consent, certificate or other instrument or paper believed by it to be
genuine and to have been properly executed by or on behalf of the Fund.  The
Custodian may receive and accept a certified copy of a vote of the Board of
Directors of the Fund as conclusive evidence (a) of the authority of any person
to act in accordance with such vote or (b) of any determination or of any action
by the Board of Directors pursuant to the Articles of Incorporation as described

share.  If so directed, the Custodian shall also calculate daily the net income

the daily income of the Fund shall be made at the time or times described from
time to time in the Fund's currently effective prospectus.

9.    Records
      -------

     The Custodian shall create and maintain all records relating to its
activities and obligations under this Contract in such manner as will meet the
obligations of the Fund under the Investment Company Act of 1940, with
particular attention to Section 31 thereof and Rules 31a-1 and 31a-2 thereunder,
applicable federal and state tax laws and any other law or administrative rules
or procedures which may be applicable to the Fund.  All such records shall be
the property of the Fund and shall at all times during the regular business
hours of the Custodian be open for inspection by duly authorized officers,
employees or agents of the Fund and employees and agents of the Securities and
Exchange Commission.  The Custodian shall, at the Fund's request, supply the
Fund with a tabulation of securities owned by the Fund and held by the Custodian
and shall, when requested to do so by the Fund and for such compensation as
shall be agreed upon between the Fund and the Custodian, include certificate
numbers in such tabulations.

10.    Opinion of Fund's Independent Accountant

     The Custodian shall take all reasonable action, as the Fund may from time
to time request, to obtain from year to year favorable opinions from the Fund's
independent accountants with respect to its activities hereunder in connection
with the preparation of the Fund's Form N-1A, and Form N-SAR or other annual
reports to the Securities and Exchange Commission and with respect to any other
requirements of such Commission.

11.    Compensation of Custodian

12.    Responsibility of Custodian
       ---------------------------

     So long as and to the extent that it is in the exercise of reasonable care,
the Custodian shall not be responsible for the title, validity or genuineness of
any property or evidence of title thereto received by it or delivered by it
pursuant to this Contract and shall be held harmless in acting upon any notice,
request, consent, certificate or other instrument reasonably believed by it to
be genuine and to be signed by the proper party or parties.  The Custodian shall
be held to the exercise of reasonable care in carrying out the provisions of
this Contract, but shall be kept indemnified by and shall be without liability
to the Fund for any action taken or omitted by it in good faith without
negligence.  It shall be entitled to rely on and may act upon advice of counsel
(who may be counsel for the Fund) on all matters, and shall be without liability
for any action reasonably taken or omitted pursuant to such advice.
Notwithstanding the foregoing, the responsibility of the Custodian with respect
to redemptions effected by check shall be in accordance with a separate
Agreement entered into between the Custodian and the Fund.

     The Custodian shall be liable for the acts or omissions of a foreign
banking institution appointed pursuant to the provisions of Article 3 to the
same extent as set forth in Article 1 hereof with respect to sub-custodians
located in the United States and, regardless of whether assets are maintained in
the custody of a foreign banking institution, a foreign securities depository or
a branch of a U.S. bank as contemplated by paragraph 3.11 hereof, the Custodian
shall not be liable for any loss, damage, cost, expense, liability or claim
resulting from, or caused by, the direction of or authorization by the Fund to
maintain custody or any securities or cash of the Fund in a foreign country
including, but not limited to, losses resulting from nationalization,
expropriation, currency restrictions, or acts of war or terrorism.


                                     -25-
<PAGE>
 
     If the Fund requires the Custodian to take any action with respect to
securities, which action involves the payment of money or which action may, in
the opinion of the Custodian, result in the Custodian or its nominee assigned to
the Fund being liable for the payment of money or incurring liability of some
other form, the Fund, as a prerequisite to requiring the Custodian to take such
action, shall provide indemnity to the Custodian in an amount and form
satisfactory to it.

     If the Fund requires the Custodian to advance cash or securities for any
purpose or in the event that the Custodian or its nominee shall incur or be
assessed any taxes, charges, expenses, assessments, claims or liabilities in
connection with the performance of this Contract, except such as may arise from
its or its nominee's own negligent action, negligent failure to act or wilful
misconduct, any property at any time held for the account of the Fund shall be
security therefor and should the Fund fail to repay the Custodian promptly, the
Custodian shall be entitled to utilize available cash and to dispose of the Fund
assets to the extent necessary to obtain reimbursement.

13.    Effective Period, Termination and Amendment
       -------------------------------------------

     This Contract shall become effective as of its execution, shall continue in
full force and effect until terminated as hereinafter provided, may be amended
at any time by mutual agreement of the parties hereto and may be terminated by
either party by an instrument in writing delivered or mailed, postage prepaid to
the other party, such termination to take effect not sooner than thirty (30)
days after the date of such delivery or mailing; provided, however that the
                                                 --------                  
Custodian shall not act under Section 2.10 hereof in the absence of receipt of
an initial certificate of the Secretary or an Assistant Secretary that the Board
of Directors of the Fund has approved the initial use of a particular Securities
System and the receipt of an annual certificate of the Secretary or an Assistant
Secretary that the Board of Directors has reviewed the use by the Fund of such
Securities System, as required 


                                     -26-
<PAGE>
 
in each case by Rule 17f-4 under the Investment Company Act of 1940, as amended
and that the Custodian shall not act under Section 2.10A hereof in the absence
of receipt of an initial certificate of the Secretary or an Assistant Secretary
that the Board of Directors has approved the initial use of the Direct Paper
System and the receipt of an annual certificate of the Secretary or an Assistant
Secretary that the Board of Directors has reviewed the use by the Fund of the
Direct Paper System; provided further, however, that the Fund shall not amend or
                     ----------------
terminate this Contract in contravention of any applicable federal or state
regulations, or any provision of the Articles of Incorporation and further
provided, that the Fund may at any time by action of its Board of Directors (i)
substitute another bank or trust company for the Custodian by giving notice as
described above to the Custodian, or (ii) immediately terminate this Contract in
the event of the appointment of a conservator or receiver for the Custodian by
the Comptroller of the Currency or upon the happening of a like event at the
direction of an appropriate regulatory agency or court of competent
jurisdiction.

     Upon termination of the Contract, the Fund shall pay to the Custodian such
compensation as may be due as of the date of such termination and shall likewise
reimburse the Custodian for its costs, expenses and disbursements.

14.    Successor Custodian
       -------------------

     If a successor custodian shall be appointed by the Board of Directors of
the Fund, the Custodian shall, upon termination, deliver to such successor
custodian at the office of the Custodian, duly endorsed and in the form for
transfer, all securities then held by it hereunder and shall transfer to an
account of the successor custodian all of the Fund's securities held in a
Securities System.

                                     -27-
<PAGE>
 
     If no such successor custodian shall be appointed, the Custodian shall, in
like manner, upon receipt of a certified copy of a vote of the Board of
Directors of the Fund, deliver at the office of the Custodian and transfer such
securities, funds and other properties in accordance with such vote.

     In the event that no written order designating a successor custodian or
certified copy of a vote of the Board of Directors shall have been delivered to
the Custodian on or before the date when such termination shall become
effective, then the Custodian shall have the right to deliver to a bank or trust
company, which is a "bank" as defined in the Investment Company Act of 1940,
doing business in Boston, Massachusetts, of its own selection, having an
aggregate capital, surplus, and undivided profits, as shown by its last
published report, of not less than $25,000,000, all securities, funds and other
properties held by the Custodian and all instruments held by the Custodian
relative thereto and all other property held by it under this Contract and to
transfer to an account of such successor custodian all of the Fund's securities
held in any Securities System.  Thereafter, such bank or trust company shall be
the successor of the Custodian under this Contract.

     In the event that securities, funds and other properties remain in the
possession of the Custodian after the date of termination hereof owing to
failure of the Fund to procure the certified copy of the vote referred to or of
the Board of Directors to appoint a successor custodian, the Custodian shall be
entitled to fair compensation for its services during such period as the
Custodian retains possession of such securities, funds and other properties and
the provisions of this Contract relating to the duties and obligations of the
Custodian shall remain in full force and effect.

15.    Interpretive and Additional Provisions
       --------------------------------------

     In connection with the operation of this Contract, the Custodian and the
Fund may from time to time agree on such provisions interpretive of or in
addition to the provisions of this Contract as may in their joint opinion be
consistent with the general tenor of this Contract.  Any such interpretive or
additional provisions shall be in a writing signed by both parties and shall be
annexed hereto, provided that no such interpretive or additional provisions
                --------                                                   
shall contravene any applicable federal or state regulations or any provision of
the Articles of Incorporation of the Fund.  No interpretive or additional

                                   EXHIBIT 1
                              CUSTODIAN AGREEMENT
                              -------------------

To:



Gentlemen:

        The undersigned ("State Street") hereby requests that you (the Bank) 
establish a custody account and a cash account for each custodian/employee 
benefit plan identified in the Schedule attached to this Agreement and each 
additional account which is identified to this Agreement. Each such custody or 
cash account as applicable will be referred to herein as the "Account" and will 
be subject to the following terms and conditions:

        1.    The Bank shall hold as agent for State Street and shall physically
              segregate in the Account such cash, bullion, coin, stocks, shares,
              bonds, debentures, notes and other securities and other property
              which is delivered to the Bank for that State Street Account (the
              "Property").

        2.    a.    Without the prior approval of State Street it will not
                    deposit securities in any securities depository or utilize a
                    clearing agency, incorporated or organized under the laws of
                    a country other than the United States, unless such
                    depository or clearing house operates the central system for
                    handling of securities or equivalent book-entries in that
                    country or operates a transnational system for the central
                    handling of securities or equivalent book-entries;

              b.    When securities held for an Account are deposited in a
                    securities depository or clearing agency by the Bank, the
                    Bank shall identify on its books as belonging to State
                    Street as agent for such Account, the securities so
                    deposited.

        3.          The Bank represents that either:

              a.    It currently has stockholders' equity in excess of $200
                    million (U.S. dollars or the equivalent of U.S. dollars
                    computed in accordance with generally accepted U.S.
                    accounting principles) and will promptly inform State Street
                    in the event that there appears to be a substantial
                    likelihood that its stockholders' equity will decline below
                    $200 million, or in any event, at such time as its
                    stockholders' equity in fact declines below $200 million; or

              b.    It is the subject of an exemptive order issued by the United
                    States Securities and Exchange Commission, which such order
                    permits State Street to employ the Bank as a subcustodian,
                    notwithstanding the fact that the Bank's stockholders'
                    equity currently below $200 million or may in the future
                    decline below $200 million due to currency fluctuation.

<PAGE>
 
        4.    Upon the written instructions of State Street, as permitted by
              Paragraph 8, the Bank is authorized to pay cash from the Account
              and to sell, assign, transfer, deliver or exchange, or to purchase
              for the Account, any and all stocks, shares, bonds, debentures,
              notes and other securities ("Securities"), bullion, coin and any
              other property, but only as provided in such written instructions.
              The bank shall not be held liable for any act or omission to act
              instructions given on purported to be given should there be any
              error in such instructions.

        5.    Unless the Bank receives written instructions of State Street to 
              the contrary, the Bank is authorized:
        
              a.    To promptly receive and collect all income and principal
                    with respect to the Property and to credit cash receipts to
                    the Account;

              b.    To promptly exchange securities where the exchange is purely
                    ministerial (including, without limitation, the exchange of

certain other activities, and PMFS desires to accept such appointment;

          NOW THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereto agree as follows:

Article 1 Terms of Appointment; Duties of PMFS
          ------------------------------------

          1.01  Subject to the terms and conditions set forth in this Agreement,
the Fund hereby employs and appoints PMFS to act as, and PMFS agrees to act as,
the transfer agent for the authorized and issued shares of the common stock of

plan or periodic withdrawal program.

               1.02  PMFS agrees that it will perform the following services:

  (viii)  Maintain records of account for and advise the Fund and its
Shareholders as to the foregoing; and

   (ix) Record the issuance of Shares of the Fund and maintain pursuant to Rule

provided to it by the Fund, and issued and outstanding.  PMFS shall also provide
to the Fund on a regular basis the total number of Shares which are authorized,
issued and outstanding and shall notify the Fund in case any proposed issue of
Shares by the Fund would result in an overissue.  In case any issue of Shares
would result in an overissue, PMFS shall refuse to issue such Shares and shall
not countersign and issue any certificates requested for such Shares.  When
recording the issuance of Shares, PMFS shall have no obligation to take
cognizance of any Blue Sky laws relating to the issue or sale of such Shares,

       (b) In addition to and not in lieu of the services set forth in the above
paragraph (a), PMFS shall:  (i) perform all of the customary services of a

Shareholder accounts, preparing and mailing activity statements for Shareholders
and providing Shareholder account information and (ii) provide a system which
will enable the Fund to monitor the total number of Shares sold in each State or
other jurisdiction.

transactions and assets to be treated as exempt from Blue Sky reporting for each
State and (ii) verify the establishment of transactions for each State on the
system prior to activation and thereafter monitor the daily activity for each
State.  The responsibility of PMFS for the Fund's registration status under the
Blue Sky or securities laws of any State or other jurisdiction is solely limited
to the initial establishment of transactions subject to Blue Sky compliance by
the Fund and the reporting of such transactions to the Fund as provided above
and as agreed from time to time by the Fund and PMFS.
