                               DATED MAY 1, 1998
    
 
                             MONY SERIES FUND, INC.
                                 1740 BROADWAY
                            NEW YORK, NEW YORK 10019
                                 1-800-487-6669
 
    MONY Series Fund, Inc. (the "Fund"), a diversified open-end management
investment company, is intended to provide a wide range of investment
alternatives through its seven separate Portfolios, each of which is, for
investment and federal tax purposes, in effect a separate fund. A separate class
of stock will be issued for each Portfolio.
 
    Shares of all Portfolios of the Fund are currently sold to MONY Life
Insurance Company of America ("MONY America") and The Mutual Life Insurance
Company of New York ("MONY") for allocation to MONY America Variable Account L
and MONY Variable Account L to fund the benefits under Flexible Premium Variable
Life Insurance Contracts issued by those companies and for allocation to MONY
America Variable Account A and MONY Variable Account A to fund benefits under
Flexible Payment Variable Annuity Contracts issued by those companies. Shares of
all Portfolios of the Fund, other than the Government Securities Portfolio, are
sold to MONY America and MONY for allocation to MONY America Variable Account S
and MONY Variable Account S to fund benefits under Variable Life Insurance with
Additional Premium Option contracts issued by those companies and to MONY for
allocation to Keynote Series Account ("Keynote") to fund benefits under
Individual Variable Annuity Contracts. These variable accounts ("Variable
Accounts") invest in shares of the Fund in accordance with allocation
instructions received from Contract holders. Such allocation rights are further
described in the attached prospectus for one of the contracts. The Variable
Accounts invest in shares of the Fund through subaccounts that correspond to the
Portfolios. The Variable Accounts will redeem shares of the Fund to the extent
necessary to provide benefits under the Contracts or for such other purposes as
may be consistent with the Contracts.
 
    The investment objectives of the Portfolios are:
 
        EQUITY INCOME PORTFOLIO:  A high level of current income, through
    investment in a diversified portfolio of common stocks with relatively high
    current yields. Capital appreciation is a secondary objective.
 
        EQUITY GROWTH PORTFOLIO:  A high level of capital appreciation through
    investment in a diversified portfolio of common stocks with potential for
    above average growth in earnings and dividends. Current income is a
    secondary objective.
 
        INTERMEDIATE TERM BOND PORTFOLIO:  The maximum income over the
    intermediate term consistent with preservation of capital, through
    investment in highly-rated debt securities, U.S. Government obligations, and
    money market instruments, together having a dollar-weighted average life of
    between 4 and 8 years.
 
        LONG TERM BOND PORTFOLIO:  The maximum income over the longer term
    consistent with preservation of capital, through investment in highly-rated
    debt securities, U.S. Government obligations, and money market instruments,
    together having a dollar-weighted average life of more than 8 years.
 
        GOVERNMENT SECURITIES PORTFOLIO:  The maximum current income over the
    intermediate term consistent with preservation of capital, through
    investment in highly-rated debt securities of the United States government
    and its agencies and money market instruments, with a dollar-weighted
    average life of up to ten years at the time of purchase.
 
        MONEY MARKET PORTFOLIO:  The maximum current income consistent with
    preservation of capital and maintenance of liquidity, through investment in
    money market instruments. The Money Market Portfolio is neither insured nor
    guaranteed by the United States Government, and, while the Money Market
    Portfolio seeks to maintain a stable net asset value of $1.00 per share,
    there is no assurance that it will be able to do so.
 
        DIVERSIFIED PORTFOLIO:  A high total investment return consistent with a
    diversified, managed mix of common stocks, bonds and money market
    instruments.
 
    There can be no assurance that the objective of any Portfolio will be
realized. See INVESTMENT OBJECTIVES AND POLICIES OF THE PORTFOLIOS at pages
11-15.

                               PROSPECTUS SUMMARY
 
     The following summary should be read in conjunction with the detailed
information appearing elsewhere in this Prospectus.
 
THE FUND
 
     MONY Series Fund, Inc. (the "Fund"), a diversified open-end management
investment company, is a Maryland corporation organized on December 14, 1984.
The Fund currently consists of seven (7) separate Portfolios: the Equity Income
Portfolio, the Equity Growth Portfolio, the Intermediate Term Bond Portfolio,
the Long Term Bond Portfolio, the Government Securities Portfolio, the Money
Market Portfolio, and the Diversified Portfolio. Each Portfolio is, for
investment and federal tax purposes, in effect a separate investment fund, and
the Fund will issue a separate class of capital stock for each Portfolio. In
other respects the Fund is treated as one entity. For more detailed information,
see STRUCTURE OF THE FUND at page 11.
 
THE ACCOUNTS AND THE CONTRACTS
 
     Shares of all Portfolios in the Fund are currently sold to MONY Life
Insurance Company of America ("MONY America") and The Mutual Life Insurance
Company of New York ("MONY") for allocation to MONY America Variable Account L
and MONY Variable Account L to fund benefits under Flexible Premium Variable
Life Insurance Contracts issued by those companies and to those companies for
allocation to MONY America Variable Account A and MONY Variable Account A to
fund benefits under Flexible Payment Variable Annuity contracts issued by those
companies. Shares of all Portfolios, other than the Government Securities
Portfolio, are also sold to the MONY America and MONY for allocation to MONY
America Variable Account S and MONY Variable Account S to fund benefits under
Variable Life Insurance with Additional Premium Option contracts issued by those
companies. In addition, shares of the Fund are sold to MONY for allocation to
Keynote Series Account ("Keynote") to fund benefits under Individual Variable
Annuity Contracts and, until June 24, 1994, were sold to MONY for allocation to
Keynote Series Account to fund benefits under Group Annuity Contracts issued by
MONY. Each Contract holder allocates the net premiums and the assets relating to
these Contracts, within the limitations described in the Contracts, among the
subaccounts of these variable accounts ("Variable Accounts") which in turn are
invested in the corresponding Portfolios of the Fund. Contract holders should
consider that the investment return experience of the Portfolios will affect the
value of the Contracts and may affect the amount of benefits received under the
Contracts. The attached prospectus for the Contracts describes the Contracts and
the relationship between changes in the value of shares of each Portfolio and
changes in the benefits payable under the Contracts. The rights of the Variable
Accounts as shareholders should be distinguished from the rights of a Contract
holder which are described in the contracts. Because the shares of the Fund will
be sold to MONY America and MONY for allocation to the Variable Accounts, the
terms "shareholder" or "shareholders" in this Prospectus refer to those
Companies.
 
INVESTMENT OBJECTIVES AND RISKS OF THE PORTFOLIOS
 
     Each of the Portfolios seeks to achieve a different investment objective.
Accordingly, each Portfolio can be expected to have different investment results
and to be subject to different financial and market risks and current income
volatility. Financial risk refers to the ability of an issuer of a debt security
to pay principal and interest on that security, and to the earnings stability
and overall financial soundness of an issuer of an equity security. Market risk
refers to the degree to which the price of a security will react to changes in
conditions in securities markets in general and, with particular reference to
debt securities, to changes in the overall level of interest rates. Current
income volatility refers to the degree and rapidity with which changes in the
overall level of interest rates become reflected in the level of current income
of the Portfolios.
 
     The investment objectives and risks of the Portfolios are:
 
     Equity Income Portfolio:  The Equity Income Portfolio seeks a high level of
current income with capital appreciation as the secondary objective. The
Portfolio will invest primarily in common stocks and other equity securities.
The Equity Income Portfolio should be subject to moderate levels of both
financial and market risk.
 
                                        1
<PAGE>   7
 
     Equity Growth Portfolio:  The Equity Growth Portfolio seeks long-term
appreciation of capital with current income as the secondary objective. The
Portfolio will invest primarily in common stocks and other equity securities.
The Equity Growth Portfolio should be subject to a moderate level of financial
risk and a somewhat higher level of market risk than the Equity Income
Portfolio.
 
     Intermediate Term Bond Portfolio:  The Intermediate Term Bond Portfolio,
having a dollar-weighted average life of between 4 and 8 years, seeks to
maximize income over the intermediate term consistent with preservation of
capital. The Portfolio will invest primarily in intermediate term bonds. The
Intermediate Term Bond Portfolio should be subject to relatively little
financial risk and a moderate level of market risk.
 
     Long Term Bond Portfolio:  The Long Term Bond Portfolio, having a
dollar-weighted average life of more than 8 years, seeks to maximize income over
the longer term consistent with preservation of capital. The Portfolio will
invest primarily in long term bonds. The Long Term Bond Portfolio should be
subject to relatively little financial risk and a higher level of market risk
than the Intermediate Term Bond Portfolio.
 
     Government Securities Portfolio:  The Government Securities Portfolio seeks
to maximize current income over the intermediate term consistent with
preservation of capital, through investment in highly-rated debt securities of
the United States government and its agencies and money market instruments, with
a dollar-weighted average life of up to ten years at the time of purchase. The
Government Securities Portfolio should be subject to relatively little financial
risk and a moderate level of market risk.
 
     Money Market Portfolio:  The Money Market Portfolio seeks to maximize
current income consistent with the preservation of capital and the maintenance
of liquidity. The Portfolio will invest primarily in money market instruments.
The Money Market Portfolio should be subject to little market risk or financial
risk but should be subject to a high level of current income volatility.
 
     Diversified Portfolio:  The Diversified Portfolio seeks a total investment
return consistent with a diversified portfolio having a managed mix of common
stocks, bonds and money market instruments. The Portfolio will invest only in
those types of securities that the Equity Income, Equity Growth, Intermediate
Term Bond, Long Term Bond, Government Securities, Money Market, and Diversified
Portfolios may invest in. The mix of investments will be determined by the
Investment Adviser based on its view of market conditions. The Diversified
Portfolio will be subject to varying levels of market and financial risk
depending upon its asset mix. It may at times be subject to a relatively high
level of current income volatility.

                             STRUCTURE OF THE FUND
 
   
     The Fund, a Maryland corporation organized on December 14, 1984, currently
is composed of seven different Portfolios that are, in effect, separate
investment funds: the Equity Income Portfolio, the Equity Growth Portfolio, the
Intermediate Term Bond Portfolio, the Long Term Bond Portfolio, the Government
Securities Portfolio, the Money Market Portfolio, and the Diversified Portfolio.
Until November 18, 1994, the Government Securities Portfolio had been known as
the Intermediate Government Bond Portfolio. The Fund issues a separate class of
capital stock for each Portfolio. Each share of capital stock issued with
respect to a Portfolio will have a pro-rata interest in the assets of that
Portfolio and will have no interest in the assets of any other Portfolio. Each
Portfolio bears its own liabilities and also its proportionate share of the
general liabilities of the Fund. The Fund is registered under the Investment
Company Act of 1940 (the "1940 Act") as an open-end, diversified, management
investment company. This registration does not imply any supervision by the
Securities and Exchange Commission over the Fund's management or its investment
policies or practices.
    
 
              INVESTMENT OBJECTIVES AND POLICIES OF THE PORTFOLIOS
 
     Each Portfolio of the Fund has a different investment objective which it
pursues through separate investment policies as described below. Since each
Portfolio has a different investment objective, each can be expected to have
different investment results and incur different market and financial risks. The
Fund may in the future establish other Portfolios with different investment
objectives.
 
     The investment objectives of each Portfolio are fundamental and may not be
changed without the approval of the holders of a majority of the outstanding
shares of the Portfolio affected (which for this purpose and under the 1940 Act
means the lesser of (i) 67 percent of the Portfolio shares represented at a
meeting at which more than 50 percent of the outstanding Portfolio shares are
represented or (ii) more than 50 percent of the outstanding Portfolio shares).
The policies by which a Portfolio seeks to achieve its investment objectives,
however, are not fundamental. They may be changed by the Board of Directors of
the Fund without shareholder approval.
 
     Each Portfolio has a different portfolio turnover rate which is the
percentage computed by dividing the lesser of portfolio purchases or sales by
the average value of the Portfolio, in each case excluding securities with
maturities at the time of acquisition of one year or less. Brokerage expenses
can be expected to be higher as a result of higher turnover rates. The rate of
portfolio turnover is not a limiting factor when it is deemed appropriate to
purchase or sell securities of a Portfolio.
 
     There is no guarantee that any of the objectives of any Portfolio will be
met. The following paragraphs describe the investment objectives, policies and
portfolio turnover rates of each Portfolio.
 
EQUITY INCOME PORTFOLIO
 
     The primary objective of the Equity Income Portfolio is a high level of
current income with capital appreciation as the secondary objective.
 
     The Equity Income Portfolio will seek to achieve this objective by
following the policy of investing primarily in a diversified portfolio of common
stocks. The stocks will have relatively high current yields, and their prices
should be less volatile than those held in the Equity Growth Portfolio.
Investments in the Equity Income Portfolio may also include securities
convertible into common stock, preferred stock, debt securities and short-term
obligations. The Equity Income Portfolio seeks to achieve this objective by
following the policy of investing primarily in common stocks listed on the New
York Stock Exchange and on other national securities exchanges and, to a lesser
extent, in stocks that are traded over-the-counter. These stocks will be
selected principally because of their dividend yield. During periods when stock
prices decline generally, the prices of stocks held in the Equity Income
Portfolio may also decline.
 
     A portion of the Equity Income Portfolio may be invested in short-term debt
obligations of the kind held in the Money Market Portfolio, as described in
Appendix A, in order to make effective use of cash reserves pending investment
in common stocks and other securities.
 
                                       11
<PAGE>   17
 
     The annual portfolio turnover rate for the Equity Income Portfolio is not
likely to exceed 100 percent.
 
EQUITY GROWTH PORTFOLIO
 
     The primary objective of the Equity Growth Portfolio is a high level of
capital appreciation with current income as the secondary objective.
 
     The Equity Growth Portfolio will seek to achieve this objective by
following the policy of investing primarily in a diversified portfolio of common
stocks. The stocks will be selected based on their potential for above average
growth in earnings and dividends. Investments in the Equity Growth Portfolio may
also include securities convertible into common stock, preferred stock, debt
securities and short-term obligations. The Equity Growth Portfolio seeks to
achieve this objective by following the policy of investing primarily in common
stocks listed on the New York Stock Exchange and on other national securities
exchanges and, to a lesser extent, in stocks that are traded over-the-counter.
These stocks will be selected principally for their potential appreciation over
the longer term. The effort to achieve a higher return necessarily involves
accepting somewhat greater risk. During periods when stock prices decline
generally, it can be expected that the value of the Equity Growth Portfolio will
also decline.
 
     A portion of the Equity Growth Portfolio may be invested in high-quality,
short-term debt obligations of the kind held in the Money Market Portfolio, as
described in Appendix A, in order to make effective use of cash reserves pending
investment in common stocks and other securities.
 
     The annual portfolio turnover rate for the Equity Growth Portfolio is not
likely to exceed 100 percent.
 
INTERMEDIATE TERM BOND PORTFOLIO
 
     The objective of the Intermediate Term Bond Portfolio is to maximize income
over the intermediate term consistent with preservation of capital.
 
     The Intermediate Term Bond Portfolio seeks to achieve this objective by
following the policy of investing in (i) debt securities which, at the time of
purchase, have a rating within the four highest grades as determined by either
Moody's Investors Service, Inc. or Standard & Poor's Corporation as described in
Appendix B; (ii) obligations of the U.S. Government, its agencies or
instrumentalities; and (iii) high-quality, short-term obligations as described
in Appendix A. The Intermediate Term Bond Portfolio will be managed so as to
maintain a dollar-weighted average life of between 4 and 8 years.
 
     Since the value of fixed income securities generally fluctuates inversely
with changes in interest rates, the average life of the Intermediate Term Bond
Portfolio will vary to reflect the Investment Adviser's assessment of
prospective changes in interest rates, so that the Intermediate Term Bond
Portfolio may benefit from relative price appreciation when interest rates
decline and may protect capital value when interest rates rise. The success of
this strategy will depend on the Investment Adviser's ability to forecast
changes in interest rates, and there is a corresponding risk that the value of
the securities held in the Portfolio will decline. Because of their relatively
shorter maturities, the value of the bonds in this Portfolio will be less
sensitive to changes in interest rates than the longer-term bonds held in the
Long Term Bond Portfolio and similar to the bonds held in the Government
Securities Portfolio. Thus, compared to the Long Term Bond Portfolio, there will
be less of a risk that the value of the securities held in the Intermediate Term
Bond Portfolio will decline, but not as much of a likelihood for greater
appreciation in value. Compared to the Government Securities Portfolio, there
will be a similar risk that the value of the securities held in the Intermediate
Term Bond Portfolio will decline and a similar likelihood for appreciation in
value.
 
     The annual portfolio turnover rate of the Intermediate Term Bond Portfolio
is not likely to exceed 100 percent.
 
LONG TERM BOND PORTFOLIO
 
     The objective of the Long Term Bond Portfolio is to maximize income over
the longer term consistent with preservation of capital.
 
                                       12
<PAGE>   18
 
     The Long Term Bond Portfolio seeks to achieve this objective by following
the policy of investing in (i) debt securities which, at the time of purchase,
have a rating within the four highest grades as determined by either Moody's
Investors Service, Inc. or Standard & Poor's Corporation as described in
Appendix B; (ii) obligations of the U.S. Government, its agencies or
instrumentalities; and (iii) high-quality, short-term obligations as described
in Appendix A. The Long Term Bond Portfolio will be managed so as to maintain a
dollar-weighted average life of in excess of 8 years.
 
     Since the value of fixed income securities generally fluctuates inversely
with changes in interest rates, the average life of the Long Term Bond Portfolio
will vary to reflect the Investment Adviser's assessment of prospective changes
in interest rates, so that the Long Term Bond Portfolio may benefit from
relative price appreciation when interest rates decline and may protect capital
value when interest rates rise. The success of this strategy will depend on the
Investment Adviser's ability to forecast changes in interest rates, and there is
a corresponding risk that the value of the securities held in the Long Term Bond
Portfolio will decline. Because of their relatively longer maturities, the value
of the bonds in this Portfolio will be more sensitive to changes in interest
rates than the relatively shorter-term bonds held in the Intermediate Term Bond
Portfolio and the Government Securities Portfolio. Thus, compared to the
Intermediate Term Bond Portfolio and the Government Securities Portfolio, there
will be more of a risk that the value of securities held in the Long Term Bond
Portfolio will decline, but more of a likelihood for greater appreciation in
value.
 
     The annual portfolio turnover rate of the Long Term Bond Portfolio is not
likely to exceed 100 percent.
 
GOVERNMENT SECURITIES PORTFOLIO
 
     The primary objective of the Government Securities Portfolio is to maximize
income over the intermediate term consistent with preservation of capital.
 
     The Government Securities Portfolio will seek to achieve this objective by
following a policy of investing in highly-rated debt securities of the United
States government and its agencies; and money market instruments. The Government
Securities Portfolio will be managed so as to maintain a dollar-weighted average
life of up to ten years at time of purchase.
 
     Since the value of fixed income securities generally fluctuates inversely
with changes in interest rates, the average life of the Government Securities
Portfolio will vary to reflect the Investment Adviser's assessment of
prospective changes in interest rates, so that the Government Securities
Portfolio may benefit from relative price appreciation when interest rates
decline and may protect capital value when interest rates rise. The success of
this strategy will depend on the Investment Adviser's ability to forecast
changes in interest rates, and there is a corresponding risk that the value of
the securities held in the Government Securities Portfolio will decline. Because
of their relatively shorter maturities, the value of the bonds in this Portfolio
will be less sensitive to changes in interest rates than the relatively
longer-term bonds held in the Long Term Bond Portfolio. Because of the
relatively similar maturities, the value of the bonds in this Portfolio will be
similar to changes in interest rates in the Intermediate Term Bond Portfolio.
Thus, compared to the Long Term Bond Portfolio, there will be less of a risk
that the value of securities held in the Government Securities Portfolio will
decline, but not as much of a likelihood for greater appreciation in value.
Compared to the Intermediate Term Bond Portfolio, there will be a similar risk
that the value of securities held in the Government Securities Portfolio will
decline and a similar likelihood for appreciation in value.
 
   
     The annual portfolio turnover rate of the Government Securities Portfolio
is not likely to exceed 100 percent.
    
 
MONEY MARKET PORTFOLIO
 
     The objective of the Money Market Portfolio is to maximize current income
consistent with the preservation of capital and maintenance of liquidity.
 
     The Money Market Portfolio seeks to achieve this objective by following the
policy of investing primarily in money market instruments denominated in U.S.
dollars that mature in 397 days or less from the date the Money Market Portfolio
acquires them. Money market instruments include short-term obligations of the
U.S.
 
                                       13
<PAGE>   19
 
Government, its agencies or instrumentalities, of domestic and foreign (if U.S.
Dollar denominated) corporations and of banks. They also include commercial
paper and other corporate obligations of both domestic and foreign (if U.S.
Dollar denominated) corporations. The Money Market Portfolio may also enter into
repurchase and reverse repurchase agreements. A detailed description of the
money market instruments in which the Money Market Portfolio may invest, of the
repurchase and reverse repurchase agreements it may enter into, and of the risks
associated with those instruments and agreements may be found in Appendix A. The
dollar-weighted average life to maturity of the securities held by the Money
Market Portfolio is expected to be less than 90 days.
 
     Because of the high-quality, short-term nature of the Money Market
Portfolio's holdings, increases in the value of an investment in the Portfolio
will be derived almost entirely from interest on the securities held by it.
 
     The Money Market Portfolio will attempt, consistent with preservation of
capital, to achieve the highest possible yield from its investments. Yield with
respect to the Money Market Portfolio normally will fluctuate, sometimes
substantially, on a daily basis and is affected by changes in interest rates on
money market instruments, average portfolio maturities, the type and quality of
portfolio securities held, and the expenses of the Money Market Portfolio.
Therefore, the yield for any given past period should not be considered as
representative of the yield for any future period.
 
     Because of the short term nature of the securities in which the Money
Market Portfolio will invest, and because the Portfolio's investments will be
constantly changing in response to market conditions, an annual portfolio
turnover rate for the Money Market Portfolio would not be meaningful and will
not be determined. The Rules of the Securities and Exchange Commission reflect
that such calculations would not be meaningful and, therefore, do not require
calculation of turnover rates for securities with a maturity of one year or
less.
 
DIVERSIFIED PORTFOLIO
 
     The objective of the Diversified Portfolio is a high total investment
return consistent with a diversified portfolio having a managed mix of common
stocks, bonds and money market instruments. The Investment Adviser will
determine the proportions of each type of investment to achieve an asset mix it
believes appropriate for an investor who desires diversification of investment.
The Investment Adviser will vary the proportion of each type of asset in the
Diversified Portfolio according to changes in economic conditions and the
sensitivity of each type of investment to those changes.
 
     The Diversified Portfolio will seek to achieve this objective by investing
in stocks and other equity securities of the kind purchased by the Equity Income
Portfolio and Equity Growth Portfolio, bonds and other fixed-income securities
of the kind purchased by the Intermediate Term Bond Portfolio, the Long Term
Bond Portfolio and the Government Securities Portfolio, and money market
instruments of the kind purchased by the Money Market Portfolio. These
investments will be made in proportions that the Investment Adviser feels
appropriate. These asset allocation decisions will be reviewed by the Investment
Adviser as necessary, given market conditions. The decision about how much to
allocate to each particular type of asset will be based on the Investment
Adviser's outlook for the economy, the financial markets and its judgment about
the relative attractiveness of each asset type.
 
     The overall annual portfolio turnover rate for the Diversified Portfolio is
not likely to exceed 100 percent. Neither the equity portion nor the bond
portion of the Diversified Portfolio is likely to have an annual turnover rate
exceeding 100 percent. No annual portfolio turnover rate may be accurately
predicted for the portion of the Portfolio invested in money market instruments
because of the short-term nature of these securities and because the Diversified
Portfolio's proportion of investment in money market instruments will be
constantly changing in response to market conditions.
 
              INVESTMENT RESTRICTIONS APPLICABLE TO THE PORTFOLIOS
 
     The Fund has adopted restrictions relating to the investment of assets of
the Portfolios and their activities. The investment restrictions are fundamental
policies and may not be changed without the approval of a majority vote of the
outstanding shares (as defined above at page 11) of each of the Portfolios
affected. (See
 
                                       14
<PAGE>   20
 
VOTING RIGHTS at page 23.) These investment restrictions, which apply to the
Fund's seven current Portfolios, may be different for any new portfolios that
the Fund may create in the future.
 
     Some of the Fund's investment restrictions have the effect of limiting
certain practices, while, however, allowing a portion of a Portfolio's net
assets to be at risk. These investment restrictions are:
 
          1. The Portfolios will not purchase real estate or real estate
     mortgages, except that the right is reserved for each Portfolio to purchase
     and sell securities which are secured by real estate or real estate
     mortgages and securities of real estate investment trusts or other issuers
     that invest or deal in the foregoing. This restriction does not apply to
     obligations issued or guaranteed by the U.S. Government, its agencies or
     instrumentalities. This restriction does not prohibit the Fund in the
     future from establishing one or more real estate portfolios.
 
          2. Loans, both short and long term, may be made by a Portfolio only
     through the purchase or acquisition of privately placed bonds, debentures,
     notes or other evidences of indebtedness that may or may not be convertible
     into stock of a type customarily acquired by institutional investors,
     provided, however, that no such purchase or acquisition will be made if, as
     a result thereof, more than 10 percent of the value of the Portfolio's
     assets would be so invested. Repurchase agreements are not subject to this
     restriction.
 
          3. Borrowing of money will not be made by any Portfolio, except as a
     temporary position for emergency purposes (to facilitate redemptions but
     not for leveraging or for investment) and then only from banks in an amount
     not exceeding 10 percent of the value of a Portfolio's assets (including
     the amount borrowed) less liabilities (not including the amount borrowed as
     a result of the borrowing) at the time such borrowing is made, and during
     any period when outstanding indebtedness for money borrowed shall exceed 5
     percent of the value of its total assets, the Portfolio will make no
     purchases of securities.
 
          4. In general, the Portfolios will not invest more than 10 percent of
     any Portfolio's total assets in illiquid assets, including illiquid
     restricted securities, repurchase agreements maturing in more than seven
     days, and nonnegotiable time deposits maturing in more than seven days.
 
     More detailed information about these investment restrictions, as well as
other investment restrictions applicable to the Portfolios, is contained in the
Statement of Additional Information (INVESTMENT RESTRICTIONS). In addition, the
Fund intends to comply with the various requirements of the Internal Revenue
Code to qualify as a "regulated investment company" under the Code. For a
description of these requirements see FEDERAL INCOME TAX STATUS on page 17.
 
LOANS OF PORTFOLIO SECURITIES
 
     Each Portfolio may from time to time lend the securities it holds to
broker-dealers, provided that the aggregate value of the securities so lent by
any Portfolio does not exceed 10 percent of the value of that Portfolio's assets
and further provided that such loans are made pursuant to written agreements and
are continuously secured by collateral in the form of cash, U.S. Government
securities, or irrevocable standby letters of credit in an amount equal to at
least the market value at all times of the loaned securities plus the accrued
interest and dividends. During the time securities are on loan, the Portfolio
will continue to receive the interest and dividends, or amount equivalent
thereto, on the loaned securities while receiving a fee from the borrower or
earning interest on the investment of the cash collateral. The right to
terminate the loan will be given to either party subject to appropriate notice.
Upon termination of the loan, the borrower will return to the lender securities
identical to the loaned securities. The Portfolio will not have the right to
vote securities on loan, but would terminate the loan and retain the right to
vote if that were considered important with respect to the investment.
 
     The primary risk in lending securities is that the borrower may become
insolvent on a day on which the loaned security is rapidly advancing in price.
In such event, if the borrower fails to return the loaned securities, the
existing collateral might be insufficient to purchase back the full amount of
the security loaned, and the borrower would be unable to furnish additional
collateral. The borrower would be liable for any shortage; but the Portfolio
would be an unsecured creditor with respect to such shortage and might not be
able to recover all
 
                                       15
<PAGE>   21
 
or any of it. However, this risk may be minimized by a careful selection of
borrowers and securities to be lent and by monitoring collateral.
 
     No Portfolio will lend securities to broker-dealers affiliated with the
Fund or MONY. This will not affect the Fund's ability to maximize a Portfolio's
securities lending opportunities.
 
STATE LAW RESTRICTIONS
 
     The investments of Keynote and the MONY Variable Accounts, and the MONY
America Variable Accounts are subject to the provisions of the New York and
Arizona insurance law, respectively, applicable to the investments of life
insurance company separate accounts. Although these state law investment
restrictions do not apply directly to the Fund, the Portfolios will comply,
without the approval of shareholders, with such statutory requirements, as they
exist or may be amended.
 
     Under pertinent provisions of New York law, as they currently exist, the
assets of Keynote and the MONY Variable Accounts may be invested in any
investments (1) permitted by agreement between these Variable Accounts and their
Contract holders and (2) acquired in good faith and with that degree of care in
acquiring investments that an ordinarily prudent person in a like position would
use under similar circumstances. The only agreement with Contract holders
pertaining to investments permitted for the Variable Accounts is as described in
the prospectuses for the Contracts, namely that the Variable Accounts will
invest only in shares of the Fund. The investment of the assets of the Fund are
subject to the investment objectives, policies and restrictions applicable to
the Portfolios, as described in this Prospectus (see INVESTMENT OBJECTIVES AND
POLICIES OF THE PORTFOLIOS at page 11 and INVESTMENT RESTRICTIONS APPLICABLE TO
THE PORTFOLIOS at page 15) and in the Statement of Additional Information
(INVESTMENT RESTRICTIONS).
 
     The pertinent provisions of Arizona law, as they currently exist, are in
summary form as follows:
 
     The assets of variable accounts established by MONY America may be invested
in any investments that are of the kind permitted and that satisfy the
qualitative requirements, but without regard to quantitative restrictions.
Bonds, debentures, notes, commercial paper and other evidences of indebtedness,
and preferred, guaranteed or preference stocks must have received an investment
grade rating approved by the Director of Insurance. Funds may not be invested in
foreign banks (other than foreign branches of domestic banks) except that
investments may be made in obligations issued, assumed or guaranteed by the
International Bank for Reconstruction and Development. Investments not otherwise
permitted under Arizona law may be made in an amount not exceeding in the
aggregate 10 percent of assets and not exceeding 2 percent of assets as to any
one such investment.
 
     Although compliance with New York and Arizona laws described above will
ordinarily result in compliance with any applicable laws of other states, under
some circumstances the laws of other states could impose additional
restrictions. Accordingly, if any state or other jurisdiction in which the
Variable Accounts propose to do business imposes limits applicable to the
Variable Accounts, in addition to any imposed by New York and Arizona law, the
Fund will comply with such further investment limits.
 
FEDERAL INCOME TAX STATUS
 
     The Fund and each of its Portfolios intend to qualify as "regulated
investment companies" under the applicable provisions of the Internal Revenue
Code of 1986, as amended (the "Code"). To qualify for treatment as regulated
investment companies, the Fund and each of its Portfolios must, among other
things, satisfy the following requirements:
 
          1. At least 90 percent of the gross income of each of the Portfolios
     must be derived from dividends, interest, payments with respect to
     securities loans (as defined in section 512(a)(5) of the Code), and gains
     from the sale or other disposition of stock or securities (as defined in
     section 2(a)(36) of the Investment Company Act of 1940, as amended) 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 stock, securities or currencies. For purposes
     of meeting this requirement, foreign
 
                                       16
<PAGE>   22
 
     currency gains which are not ancillary to the Portfolio's principal
     business of investing in stock or securities (or options and futures with
     respect to stock or securities) may be excluded from qualifying income.
 
          2. Each Portfolio must derive less than 30 percent of its gross income
     in each taxable year from the sale or other disposition of stock,
     securities held for less than 3 months, options, futures, forward
     contracts, or foreign currency gains not related to a Portfolio's principal
     business of investing in stock or securities. No portfolio will be
     disqualified under this test by reason of sales resulting from abnormal
     redemptions on any day occurring before the close of the fifth business day
     after such day if the sum of the percentages of assets redeemed, for any
     day on which such percentage exceeds 1% for the day in question and any
     prior day in the taxable year exceeds 30% and the Fund would meet this test
     if all its portfolios were treated as a single company.
 
          3. At the close of each calendar quarter, at least 50 percent of the
     value of the total assets of each of the Portfolios must be represented by
     cash and cash items (including receivables), Government securities,
     securities of other regulated investment companies, and other securities
     (limited for each portfolio in respect of any one issuer, to an amount not
     greater in value than 5 percent of the value of the total assets of that
     Portfolio and to not more than 10 percent of the outstanding voting
     securities of the issuer).
 
          4. At the close of each calendar quarter, no more than 25 percent of
     the value of the total assets of each of the Portfolios may be invested in
     the securities of any one issuer except that this limitation shall not
     apply to Government securities or securities of other regulated investment
     companies. In addition, at the close of each calendar quarter, no more than
     25 percent of the value of the total assets of each of the Portfolios may
     be invested in the securities of 2 or more issuers which the Portfolio
     controls and which are engaged in the same or similar trades or businesses.
 
     For substantially all federal income tax purposes, each Portfolio of the
Fund is a separate entity. This means that the investment results of each
Portfolio will be calculated separately from those of the other Portfolios for
purposes of determining whether each Portfolio qualifies as a regulated
investment company and for purposes of determining the net ordinary income (or
loss) and net realized capital gains (or losses).
 
     For information regarding the federal income tax implications of the Fund
and its Portfolios qualifying as a regulated investment company, see DIVIDENDS,
DISTRIBUTIONS AND TAXES at pages 24.
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations currently in effect. For the
complete provisions, reference should be made to the pertinent Code Sections and
Treasury Regulations. The Code and these Regulations are subject to change by
legislative, administrative or judicial actions.

                             MANAGEMENT OF THE FUND
 
     The Board of Directors of the Fund is responsible for the management of the
business of the Fund under the laws of the State of Maryland, and it is
primarily responsible for reviewing the activities of the investment adviser.
 
INVESTMENT MANAGEMENT ARRANGEMENTS AND EXPENSES
 
     The Fund has entered into an Investment Advisory Agreement with MONY
America under which MONY America will carry on the overall day-to-day management
of the Equity Income, Equity Growth, Intermediate Term Bond, Long Term Bond,
Government Securities, Money Market, and Diversified Portfolios of the Fund, and
provide investment advice and related services for each of those Portfolios. If
the Fund creates new portfolios in the future, MONY America may be appointed to
act as investment adviser and manager for those portfolios, as well, or the Fund
may appoint a different investment adviser for any new portfolio.
 
   
     MONY America receives an investment management fee as compensation for its
services to each of the Equity Income, Equity Growth, Intermediate Term Bond,
Long Term Bond, Government Securities and Diversified Portfolios of the Fund.
The fee is a daily charge equal to an annual rate of .50 percent of the first
$400 million of the aggregate average daily net assets of each of those
Portfolios, .35 percent of the next $400 million of the aggregate average daily
net assets of each of those Portfolios, and .30 percent of the aggregate average
daily net assets of each of those Portfolios in excess of $800 million and for
the Money Market Portfolio is a daily charge equal to an annual rate of .40
percent of the first $400 million of the aggregate average daily net assets of
the Portfolio, .35 percent of the next $400 million of the aggregate average
daily net assets of the Portfolio, and .30 percent of the aggregate average
daily net assets in excess of $800 million. MONY America has agreed to bear all
expenses (i) for the Fund's organization, (ii) related to initial registration
and qualification under federal and state securities laws, and (iii) for
compensation of the Fund's directors, officers and employees who are interested
persons (as defined by the 1940 Act) of MONY America. All other expenses,
including those associated with calculating net asset value of the Portfolios
and any extraordinary or non-recurring expenses will be borne by the Fund. With
respect to the expenses of preparing, printing and mailing prospectuses, see
PURCHASE AND REDEMPTION OF SHARES at page 21.
    
 
     MONY America, a wholly-owned subsidiary of MONY, is registered as an
investment adviser under the Investment Advisers Act of 1940 and, prior to
registration in 1985, had not performed services as an investment adviser. MONY
America has entered into a Services Agreement with MONY to provide it with
personnel, services, facilities, supplies, and equipment in order to carry out
many of its duties to provide investment management services under the
Investment Advisory Agreement. MONY America pays MONY for such services.
 
     Because the Investment Advisory Agreement and the Services Agreement are
interrelated and dependent on each other, MONY may be deemed to be an investment
adviser of the Fund for certain federal regulatory purposes. MONY is registered
as an investment adviser under the Investment Advisers Act of 1940. Its
principal business address, as well as that of the Investment Adviser, is 1740
Broadway, New York, New York 10019.
 
   
     Although MONY America's lack of previous experience in advising a mutual
fund might be considered a risk factor, it is anticipated that many of MONY
America's duties will be carried out by MONY and its personnel under the
Services Agreement and therefore MONY's experience as an investment manager
should also be considered. MONY is a mutual life insurance company organized
under the laws of New York in 1842 and licensed to do business in all fifty
states, the District of Columbia, Puerto Rico, the Virgin Islands and certain
Canadian provinces. MONY manages the investment of assets held in its own
general account, various separate accounts established by MONY, and the assets
of its employee thrift plan trust. From 1969 to 1981, MONY provided investment
advisory services to MONY Advisers, Inc. (a wholly-owned subsidiary of MONY)
which acted as investment adviser to The MONY Fund, Inc., a registered
diversified open-end management investment company. As of December 31, 1997,
total assets under management in the accounts managed by MONY and MONY America
were approximately $22.0 billion and included common stocks
    
 
                                       18
<PAGE>   24
 
   
with a value of approximately $1.2 billion, long and medium term publicly-traded
fixed income securities with a value of approximately $7.6 billion, and
short-term debt obligations with a value of approximately $409.9 million. The
size of the accounts and portfolios managed by MONY or its personnel does not
assure that a shareholder of the Fund will realize any gain or be protected from
any loss.
    
 
   
     The Investment Advisory Agreement was initially approved by the Fund's
Board of Directors, including a majority of the non-interested directors (as
defined by the 1940 Act), on January 2, 1985. The agreement was amended
effective August 4, 1997, and the Amended Investment Advisory Agreement was
approved by the shareholders on October 14, 1997. The continuance of the Amended
Investment Advisory Agreement was approved by the Fund's Board of Directors on
February 18, 1998. The Services Agreement was similarly approved on January 2,
1985 and continuance for an additional year was most recently approved by the
Fund's Board of Directors on February 18, 1998. Both Agreements will continue in
effect if approved annually by (1) a majority of the non-interested directors
(as defined by the 1940 Act) of the Fund's Board of Directors, and (2) a
majority of the entire Board of Directors or a majority vote of the voting
shares of each Portfolio. If a majority of the voting shares of any Portfolio
vote to approve both Agreements, they will remain in effect with respect to that
Portfolio, even if they are not approved by a majority of the voting shares of
any other Portfolio or by a majority of the voting shares of the entire Fund.
The Agreements are not assignable. The Investment Advisory Agreement may be
terminated without penalty upon 60 days' notice by the Fund's Board of Directors
or by a majority vote of its shareholders, and upon 90 days' notice by the
Investment Adviser. The Services Agreement may be terminated without penalty
upon 60 days' notice by either party.
    
 
     MONY America and MONY serve as investment managers or advisers in managing
their own assets and, in the case of MONY, the assets of separate accounts and
certain of its subsidiaries. In the future, MONY America and MONY may serve as
investment manager or adviser to other investment companies. When investment
opportunities arise that may be appropriate for more than one account or entity
for which MONY America or MONY serves as investment manager or adviser,
including for their own accounts, MONY America or MONY and their personnel will
not favor one over another and may allocate investments among them in an
impartial manner believed to be equitable to each entity involved. The
allocations will be based on each entity's investment objectives and its current
cash and investment positions. Because the various entities for which MONY
America or MONY acts or may act as investment manager or adviser, including for
their own accounts, have different investment objectives and positions, MONY
America or MONY may from time to time buy a particular security for one or more
such entities while at the same time it sells such securities for another.
 
RESPONSIBILITY FOR DAY-TO-DAY MANAGEMENT OF THE FUND
 
     As investment adviser, MONY America is responsible for the day-to-day
management of each of the Portfolios of the Fund. Investment decisions are made
by a committee of the investment adviser.
 
   
YEAR 2000 ISSUE
    
 
   
     MONY America has conducted a comprehensive review of the computer systems
used in connection with the Fund. A new Year 2000 compliant software program
used for fund accounting has been purchased to replace the system currently
used. It currently is being tested. MONY America has received assurances from
suppliers of services that systems used in connection with the Fund are being
modified and converted. MONY America will monitor the status of these efforts.
    
 
CUSTODIAN, TRANSFER AGENT, AND DIVIDEND DISBURSING AGENT
 
     Chase Manhattan Bank, 4 New York Plaza, New York, New York 10004 is the
custodian of the securities held by the Portfolios of the Fund, and is
authorized to use the facilities of the Depository Trust Company and the
facilities of the book-entry system for the Federal Reserve Bank. The Fund acts
as its own transfer agent and dividend-disbursing agent.
 
                                       19
<PAGE>   25
 
                       PURCHASE AND REDEMPTION OF SHARES
 
     Shares in the Fund are currently being offered continuously, without sales
charge at the Fund level, at prices equal to the respective net asset values of
the Portfolios to MONY and MONY America for allocation to the Variable Accounts
to fund benefits payable under the Contracts described in the attached
prospectus. The Fund sells its shares through MONY Securities Corp. ("MSC")
(which acts as "principal underwriter" of the Contracts and therefore of the
shares of the Fund) to MONY and MONY America, for allocation to the Variable
Accounts. MSC is registered as a broker-dealer under the Securities Exchange Act
of 1934 and is a member of the National Association of Securities Dealers. It is
expected that there will be no distribution expenses for the Fund, other than
expenses for preparing, printing and mailing prospectuses. These expenses, and
any other distribution expenses, will be borne by MSC pursuant to an
underwriting agreement that will comply with pertinent provisions of the 1940
Act and rules of the Securities and Exchange Commission under that Act. The Fund
may at some later date also offer its shares to other separate accounts of MONY,
MONY America, or other MONY subsidiaries.
 
     The Fund is required to redeem all full and fractional shares of the Fund
for cash within seven days of receipt of proper notice of redemption. The
redemption price is the net asset value per share next determined after the
initial receipt of proper notice of redemption.
 
     The right to redeem shares or to receive payment with respect to any
redemption may be suspended only (i) for any period during which trading on the
New York Stock Exchange is restricted as determined by the Securities and
Exchange Commission or when the New York Stock Exchange is closed (other than
customary weekend and holiday closings), (ii) for any period during which an
emergency exists as defined by the Securities and Exchange Commission as a
result of which disposal of a Portfolio's securities or determination of the net
asset value of each Portfolio is not reasonably practicable, and (iii) for such
other periods as the Securities and Exchange Commission may by order permit for
the protection of shareholders of each Portfolio.
 
                        DETERMINATION OF NET ASSET VALUE
 
     The net asset value of the shares of each Portfolio will be determined by
the Investment Adviser once daily immediately after the declaration of
dividends, if any, at a time to be determined by the Fund's Board of Directors,
currently 4:00 p.m. New York City time, on each day during which the New York
Stock Exchange is open for business or on any other day in which there is
sufficient trading in the securities held by a Portfolio to result in a material
change in the value of such shares. The net asset value per share of each
Portfolio except the Money Market Portfolio is computed by adding the sum of the
value of the securities held by that Portfolio plus any cash or other assets it
holds, subtracting all its liabilities, and dividing the result by the total
number of shares outstanding of that Portfolio at such time. Expenses, including
the investment management fee payable to MONY America, are accrued daily.
 
     High-quality, short-term debt obligations held in any of the Portfolios
with a remaining maturity of 60 days or less will be valued on an amortized-cost
basis. This means that each obligation will be valued initially at its purchase
price and thereafter by amortizing any discount or premium uniformly to
maturity, regardless of the impact of fluctuating interest rates on the market
value of the obligation. This highly practical method of valuation is in
widespread use and almost always results in a value that is extremely close to
the actual market value. The Fund's Board of Directors will review obligations
being valued under this method where credit or other factors may indicate the
method is not appropriate or where the rules of the Securities and Exchange
Commission require such examination. Short-term debt obligations with a
remaining maturity of more than 60 days will be valued in the same way as are
debt securities held in the Intermediate Term Bond, Long Term Bond and
Government Securities Portfolios, as described below in "Valuation of
Intermediate Term Bond, Long Term Bond and Government Securities Portfolios".
 
                                       20
<PAGE>   26
 
VALUATION OF EQUITY INCOME AND EQUITY GROWTH PORTFOLIOS
 
     The net asset value of the securities held in Equity Income and Equity
Growth Portfolios, other than short-term obligations valued on an amortized-cost
basis, will be determined in the following manner. Each security traded on a
national securities exchange will be valued at the price which, on the date of
valuation, is the last sales price (or the last bid price if there were no sales
of the security on that day) on the New York Stock Exchange, or if not traded on
the New York Stock Exchange, such last sales or bid price on the principal
exchange on which such security is traded at the time of close of the New York
Stock Exchange. For any securities not traded on a national securities exchange
but traded in the over-the-counter market, the value will be the last bid price
available at the time of close of the New York Stock Exchange, except that the
securities for which quotations are furnished through a nationwide automated
quotation system approved by the NASDAQ will be valued at the closing best bid
price so furnished on the date of valuation.
 
VALUATION OF INTERMEDIATE TERM BOND, LONG TERM BOND AND GOVERNMENT SECURITIES
PORTFOLIOS
 
     In determining the net asset value of securities held in the Intermediate
Term Bond, Long Term Bond, and Government Securities Portfolios, securities will
be valued based on a decision as to the broadest and most representative market
for such security. The value will be based on either (i) the last available sale
price on a national securities exchange, (ii) in the absence of recorded sales,
the average of readily available closing bid and asked prices on national
securities exchanges, or (iii) the average of the quoted bid and asked prices in
the over-the-counter market. Securities or assets for which market quotations
are not readily available will be valued at fair value as determined by the
Investment Adviser under the direction of the Board of Directors of the Fund.
 
VALUATION OF MONEY MARKET PORTFOLIO
 
     The net asset value of shares of the Money Market Portfolio will normally
remain at $1.00 per share, because the net investment income of this Portfolio
(including realized and unrealized gains and losses on Portfolio holdings) will
be declared as a dividend each time the Portfolio's net income is determined
(see DIVIDENDS, DISTRIBUTIONS AND TAXES, at page 23). If in the view of the
Board of Directors of the Fund it is inadvisable to continue to maintain the net
asset value of the Money Market Portfolio at $1.00 per share, the Board reserves
the right to alter the procedure. The Fund will notify Shareholders of any such
alteration.
 
     The Fund will value all short-term debt obligations held in the Money
Market Portfolio on an amortized-cost basis. The regulations of the Securities
and Exchange Commission (SEC) require that, as a condition for using amortized
cost valuation, the Money Market Portfolio (i) maintain a dollar-weighted
average portfolio maturity not exceeding 90 days, and (ii) limit its portfolio
investments to those United States dollar-denominated instruments determined to
present minimal credit risks and which at the time of acquisition are Eligible
Securities. Eligible Securities include any security (i) issued with, or with a
remaining maturity of, 397 days or less which is rated (or, if unrated, the
issuer of which also issues short-term securities any one of which, comparable
in priority and security, is rated) by an SEC designated statistical rating
organization in one of the two highest rating categories for short-term debt
obligations; or (ii) the issuer of which does not have any securities which have
a short term rating but which security is (x) comparable in priority and
security to a security which has been rated in one of the two highest rating
categories for short term debt obligations by an SEC designated statistical
rating organization, and (y) not a security which had an original maturity in
excess of 397 days and which received a rating as a long term debt obligation
from such a rating organization that was not within the two highest rating
categories. In the event of sizable changes in interest rates, however, the
value determined by amortized cost valuation may be higher or lower than the
price that would be received if the obligation were sold. On these occasions (if
any should occur) as a further condition to using amortized-cost valuation,
procedures have been established by the Board of Directors to determine whether
the deviation might be enough to affect the value of shares in the Money Market
Portfolio by more than one-half of one percent, and if it does, an appropriate
adjustment will be made in the value of the obligations.
 
                                       21
<PAGE>   27
 
VALUATION OF DIVERSIFIED PORTFOLIO
 
     In determining the net asset value of the Diversified Portfolio, the method
of valuation of a security will depend on the type of investment involved. A
security which is a common stock will be valued in the same way as securities
held in the Equity Income Portfolio or Equity Growth Portfolio; a security which
is an intermediate or long-term fixed income security in the same way as
securities held in the Intermediate Term Bond Portfolio, Long Term Bond
Portfolio, and Government Securities Portfolio, and short-term debt obligations
held in the Diversified Portfolio (other than those valued on an amortized-cost
basis) will be valued in the same way as debt securities held in the
Intermediate Term Bond Portfolio, Long Term Bond Portfolio or Government
Securities Portfolio.
 
                               SHARES IN THE FUND
 
     The authorized capital stock of the Fund consists of 2 billion shares, par
value $.01 per share. The shares of capital stock are divided into seven
classes: Equity Income Portfolio Capital Stock (150 million shares); Equity
Growth Portfolio Capital Stock (150 million shares); Intermediate Term Bond
Portfolio Capital Stock (150 million shares); Long Term Bond Portfolio Capital
Stock (150 million shares); Government Securities Portfolio Capital Stock (150
million shares); Money Market Portfolio Capital Stock (250 million shares); and
Diversified Portfolio Capital Stock (150 million shares). The Fund may in the
future allocate some of the remaining authorized shares to these classes, or
create new classes of capital stock corresponding to new portfolios and allocate
some of the remaining authorized shares to such new classes and then issue
shares of such new classes. Each share of stock will have a pro-rata interest in
the assets of the Portfolio to which the stock of that class relates and will
have no interest in the assets of any other Portfolio. Holders of shares of any
Portfolio are entitled to redeem their shares as set forth under PURCHASE AND
REDEMPTION OF SHARES at page 21. The shares of each Portfolio, when issued, will
be fully paid and non-assessable, will have no preemptive, conversion, exchange
or similar rights, and will be freely transferable. The shares do not have
cumulative voting rights. Holders of more than 50 percent of the shares of the
Fund voting for the election of directors can, if they choose to do so, elect
all of the Fund's directors, and in such event the holders of the remaining
shares would not be able to elect any directors.
 
     MONY provided the initial capital for each of the Fund's Portfolios. MONY
held shares attributable to its initial capital investment. At December 31,
1993, MONY had redeemed all shares attributable to its initial capital
investment, except that MONY provided $1,000,000 in capital to the Government
Securities Portfolio on November 18, 1994. Additional shares may be acquired by
MONY during the Fund's operation or any new portfolio's start-up period. The
acquisition of shares by MONY will enable the Portfolios (or any new portfolios)
to avoid an unrealistically poor investment performance that might otherwise
result because the amounts available for investment were too small, as well as
to satisfy the net worth requirements of the 1940 Act. MONY may also acquire
additional shares through dividend reinvestment in connection with the shares
acquired during the start-up period. Any shares acquired by MONY (other than for
allocation to MONY Variable Account A, MONY Variable Account L, MONY Variable
Account S, or the Keynote Series Account) will be acquired for investment and
can be disposed of only by redemption. They will not be redeemed by MONY until
the other assets of the Portfolios are large enough so that redemption will not
have an adverse effect upon investment performance. MONY will vote these shares
in the same proportion as the shares held in the Variable Accounts, which
generally are voted in accordance with the instructions of Contract holders.
 
VOTING RIGHTS
 
     All shares of capital stock of the Fund have equal voting rights
(regardless of the net asset value per share) except that only shares of the
respective Portfolios are entitled to vote on matters concerning only that
Portfolio. Pursuant to the 1940 Act and the rules and regulations thereunder,
certain matters approved by a vote of all shareholders of the Fund may not be
binding on a Portfolio whose shareholders have not approved that matter. Each
outstanding share of each Portfolio is entitled to one vote and to participate
equally in
 
                                       22
<PAGE>   28
 
dividends and distributions declared by that Portfolio and, upon dissolution or
liquidation, in the Portfolio's net assets after satisfying outstanding
liabilities.
 
     The voting rights of Contract holders, and limitations on those rights, are
explained in the accompanying prospectus for the Contract. MONY and MONY America
as the owners of the assets in the Variable Accounts, are entitled to vote all
of the shares of the Fund attributable to the Variable Accounts, but they will
generally do so in accordance with the instructions of Contract holders. Under
certain circumstances, however, MONY and MONY America may disregard voting
instructions received from Contract holders. The Fund might under these
circumstances be deemed to be controlled by MONY and MONY America by virtue of
the definitions contained in the 1940 Act although the Fund disclaims that such
control exists.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
 
     The Fund and each of its portfolios intend to qualify as "regulated
investment companies" under the applicable provisions of the Internal Revenue
Code of 1986, as amended (the "Code"). For a description of the restrictions
that apply to qualifying as a regulated investment company, see FEDERAL INCOME
TAX STATUS at page 17. Under those provisions, the Fund and each of its
portfolios will not be subject to federal income tax on the portion of its net
ordinary income and net realized capital gains that each portfolio distributes
to MONY and MONY America, for allocation to the Variable Accounts or to MONY
with respect to shares acquired with initial or additional capital. Since the
only shareholders of the Fund will be MONY and MONY America there is no
discussion in this Prospectus of the federal income tax consequences at the
shareholder level. For information concerning the federal tax consequences to
the Contract holders, see the attached prospectus for the Contracts.
 
     The Fund intends to distribute as dividends substantially all the net
ordinary income, if any, of each Portfolio. For dividend purposes, net ordinary
income of each Portfolio, other than the Money Market Portfolio and the
short-term debt portion of any other Portfolio, consists of (i) all dividends
received (other than stock dividends), (ii) plus all interest and other ordinary
income accrued, (iii) plus all short-term capital gains realized, (iv) less the
expenses of such Portfolio (including fees payable to the Investment Adviser).
Net ordinary income of the Money Market Portfolio and the short-term debt
portion of any other Portfolio consists of (i) interest accrued and/or discount
earned (including both original issue and market discount), (ii) plus all
realized net short-term capital gains, (iii) less the expenses of the Portfolio
(including the fees payable to the Investment Adviser). Dividends on the Money
Market Portfolio will be declared and reinvested daily in additional full and
fractional shares of the Portfolio. Shares corresponding to the Money Market
Portfolio will begin accruing dividends on the day following the date on which
they are issued. Dividends from investment income of the other Portfolios will
be declared and reinvested in additional full and fractional shares annually,
although the Fund may make distributions more frequently, except that MONY may
elect to receive dividends on the shares acquired to provide operating capital
in cash.
 
     The Fund will normally declare and distribute annually all net realized
capital gains of each portfolio of the Fund (other than short-term gains of the
Money Market Portfolio, which are declared as dividends daily). In determining
the amount of capital gains to be distributed, the realized capital gains and
losses of each of the Portfolios are calculated separately. This will not cause
any of the Portfolios to have a different investment performance than it would
if it were taxed, together with the other Portfolios, as a single investment
company and it will not affect the value of Contract holders' interests under
the Contracts.
 
     The Fund and each of its Portfolios intend to declare dividends for each
calendar year payable to shareholders of record as of a specified date and
distribute such dividends in March of the following calendar year. In
determining the capital gains distribution, the Fund and each of its Portfolios
will calculate net realized capital gains for each calendar year.
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations currently in effect. For the
complete provisions, reference should be made to the pertinent Code Sections and
Treasury Regulations. The Code and these Regulations are subject to change by
legislative, administrative or judicial actions.

SHAREHOLDER REPORTS AND INQUIRIES
 
     The Fund will send each shareholder, at least annually, reports showing as
of a specified date the number of shares in each Portfolio credited to the
shareholder. The Fund will also send Contract holders semiannual reports showing
the financial condition of the Portfolios and the investments held in each. The
annual report may take the form of an updated copy of the Prospectus.
 
                  CALCULATION OF PERFORMANCE OF THE PORTFOLIOS
 
     From time to time the performance of one or more of the Portfolios may be
advertised. The performance data contained in these advertisements is based upon
historical earnings and is not indicative of future performance. The data for
each Portfolio reflects the results of that Portfolio of the Fund and recurring
charges and deductions borne by or imposed on the Portfolio. Set forth below for
each Portfolio is the manner in which the data contained in such advertisements
will be calculated.
 
     Money Market Portfolio.  The performance data for this Portfolio will
reflect the "yield" and "effective yield". The "yield" of the Portfolio refers
to the income generated by an investment in the Portfolio over the seven day
period stated in the advertisement. This income is "annualized", that is, the
amount of income generated by the investment during that week is assumed to be
generated each week over a 52-week period and is shown as a percentage of the
investment. The "effective yield" is calculated similarly, but, when annualized,
the income earned by an investment in the Portfolio is assumed to be reinvested.
The "effective yield" will be slightly higher than the "yield" because of the
compounding effect of this assumed reinvestment.
 
     All Other Portfolios.  The performance data for the Portfolios will reflect
the "yield" and "total return". The "yield" of each of the Portfolios (except
for a 7 day period for the Money Market Portfolio) refers to the income
generated by an investment in that Portfolio over the 30 day period stated in
the advertisement and is the result of dividing that income by the value of the
Portfolio. The value of each Portfolio is the average daily number of shares
outstanding multiplied by the net asset value on the last day of the period.
"Total return" for each of these Portfolios refers to the return a Shareholder
would receive during the period indicated if a $1,000 investment was made the
indicated number of years ago. It reflects investment results less charges and
deductions of the Fund. Returns for periods exceeding one year reflect the
average annual total return for such period. Total return data may also be shown
for larger investments which would reflect the average size purchase payment
made for Contracts, the purchasers of which may allocate purchase payments to
Subaccounts which purchase shares of the Portfolios of the Fund.
 
   
     In addition, reference in advertisements may be made to various indices,
including, without limitation, the Standard & Poor's 500 Stock Index and the
Lehman Brothers Government/Corporate Index, and to various ranking services,
including, without limitation, the Lipper Annuity and Closed End Survey compiled
by Lipper Analytical Services and the VARDS report compiled by Variable Annuity
Research and Data Service in order to provide the reader a basis for comparison.

                                                                      APPENDIX A
 
                      SECURITIES IN WHICH THE MONEY MARKET
                         PORTFOLIO MAY CURRENTLY INVEST
 
     The Money Market Portfolio, and the other Portfolios to the extent their
investment policies so provide, may invest in the following short-term, debt
securities regularly bought and sold by financial institutions:
 
          1. U.S. Treasury Bills, other obligations issued or guaranteed by the
     U.S. Government, obligations of U.S. agencies or instrumentalities which
     are backed by the U.S. Treasury, and obligations issued or guaranteed by
     U.S. agencies or instrumentalities and backed solely by the issuing agency
     or instrumentality. These are debt securities (including bills,
     certificates of indebtedness, notes, and bonds) issued or guaranteed by the
     U.S. Treasury or by an agency or instrumentality of the U.S. Government
     that is established under the authority of an act of Congress. Such
     agencies or instrumentalities include, but are not limited to, the Federal
     National Mortgage Association, the Federal Farm Credit Bank, the Federal
     Home Loan Bank and the Government National Mortgage Association. Although
     all obligations of agencies and instrumentalities are not direct
     obligations of the U.S. Treasury, payment of the interest and principal on
     them is generally backed directly or indirectly by the U.S. Treasury. This
     support can range from the backing of the full faith and credit of the
     United States, to U.S. Treasury guarantees, or to the backing solely of the
     issuing agency or instrumentality itself.
 
          2. Obligations (including certificates of deposit, bankers'
     acceptances and time deposits) of any bank organized under the laws of the
     United States or any state thereof or of foreign branches of such banks or
     foreign banks, provided that such bank has, at the time of the Portfolio's
     investment, total assets of at least $1 billion or the equivalent. The term
     "certificates of deposit" includes both Eurodollar certificates of deposit,
     which are traded in the over-the-counter market, and Eurodollar time
     deposits, for which there is generally not a market and Yankee certificates
     of deposit. "Eurodollars" are dollars deposited in banks outside the United
     States and Yankee certificates of deposit are certificates of deposit
     denominated in U. S. dollars and issued in the United States by the
     domestic branch of a foreign bank and are primarily traded in the United
     States. An investment in Eurodollar instruments involves risks that are
     different in some respects from an investment in debt obligations of
     domestic issuers, including future political and economic developments such
     as possible expropriation or confiscatory taxation that might adversely
     affect the payment of principal and interest on the Eurodollar instruments.
     In addition, foreign branches of domestic banks and foreign banks may not
     be subject to the same accounting, auditing and financial standards and
     requirements as domestic banks. Finally, in the event of default, judgments
     against a foreign branch or foreign bank might be difficult to obtain or
     enforce. Yankee certificates have risks substantially similar to those of
     Eurodollar certificates.
 
          "Certificates of deposit" are certificates evidencing the indebtedness
     of a commercial bank to repay funds deposited with it for a definite period
     of time (usually from 14 days to one year). "Bankers' acceptances" are
     credit instruments evidencing the obligation of a bank to pay a draft which
     has been drawn on it by a customer. These instruments reflect the
     obligation both of the bank and of the drawer to pay the face amount of the
     instrument upon maturity. "Time deposits" are non-negotiable deposits in a
     bank for a fixed period of time.
 
          3. Commercial paper issued by corporations which at the date of
     investment is rated (a) by any two SEC designated statistical rating
     organizations in one of the two highest rating categories for short-term
     debt obligations or, (b) if not rated, issued by domestic or foreign
     corporations which have an outstanding senior long-term debt issue rated by
     any two SEC designated statistical rating organizations in one of the two
     highest rating categories for short-term debt obligations. "Commercial
     paper" consists of short-term (usually from 1 to 270 days) unsecured
     promissory notes issued by corporations in order to finance their current
     operations. If the commercial paper is issued by a foreign corporation, it
     must be U.S. Dollar denominated.
 
                                       A-1
<PAGE>   31
 
          4. Other corporate obligations issued by domestic or foreign
     corporations which at the date of investment are rated by any two SEC
     designated statistical rating organizations in one of the two highest
     rating categories for short-term debt obligations. "Corporate obligations"
     are bonds and notes issued by corporations and other business
     organizations, including business trusts, in order to finance their long-
     term credit needs. If the obligation is issued by a foreign corporation, it
     must be U.S. Dollar denominated.
 
          5. Repurchase Agreements.  When the Money Market Portfolio purchases
     money market securities of the types described above, it may on occasion
     enter into a repurchase agreement with the seller wherein the seller and
     the buyer agree at the time of sale to a repurchase of the security at a
     mutually agreed upon time and price. The period of maturity 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 price,
     reflecting an agreed-upon market rate of interest effective for the period
     of time the Portfolio's money is invested in the security, and is not
     related to the coupon rate of the purchased security. Repurchase agreements
     may be considered loans of money to the seller of the underlying security,
     which are collateralized by the securities underlying the repurchase
     agreement. The Fund will not enter into repurchase agreements unless the
     agreement is "fully collateralized," i.e., the value of the securities is,
     and during the entire term of the agreement remains, at least equal to the
     amount of the "loan" including accrued interest. The Fund's custodian bank
     will take possession of the securities underlying the agreement, and the
     Fund will value them daily to assure that this condition is met. The Fund
     has adopted standards for the parties with whom it will enter into
     repurchase agreements which it believes are reasonably designed to assure
     that such a party presents no serious risk of becoming involved in
     bankruptcy proceedings within the time frame contemplated by the repurchase
     agreement. In the event that a seller defaults on a repurchase agreement,
     the Fund may incur a loss in the market value of the collateral, as well as
     disposition costs; and, if a party with whom the Fund had entered into a
     repurchase agreement becomes involved in bankruptcy proceedings, the Fund's
     ability to realize on the collateral may be limited or delayed and a loss
     may be incurred if the collateral security of the repurchase agreement
     declines in value during the bankruptcy proceedings.
 
          6. Reverse Repurchase Agreements.  The Portfolio may enter into
     reverse repurchase agreements with banks, which agreements have the
     characteristics of borrowing and involve the sale of securities held by the
     Portfolio with an agreement to repurchase the securities at an agreed-upon
     price and date, which reflect a rate of interest paid for the use of funds
     for the period. Generally, the effect of such a transaction is that the
     Portfolio can recover all or most of the cash invested in the securities
     involved during the term of the reverse repurchase agreement, while in many
     cases it will be able to keep some of the interest income associated with
     those securities. Such transactions are only advantageous if the Portfolio
     has an opportunity to earn a greater rate of interest on the cash derived
     from the transaction than the interest cost of obtaining that cash. The
     Portfolio may be unable to realize a return from the use of the proceeds
     equal to or greater than the interest required to be paid. Opportunities to
     achieve this advantage may not always be available, and the Portfolio
     intends only to use the reverse repurchase technique when it appears to be
     to its advantage to do so. The use of reverse repurchase agreements may
     magnify any increase or decrease in the value of the Portfolio's
     securities. The Fund's custodian bank will maintain in a separate account
     securities of the Portfolio that have a value equal to or greater than the
     Portfolio's commitments under reverse repurchase agreements.
 
   
          7. Asset Backed Securities.  Asset backed securities are securities
     that have been structured to receive payment from an identified pool of
     assets. These pools are typically overcollateralized or they have some sort
     of financial guaranty such as a letter of credit or a third party guaranty
     to ensure full and timely repayment.
    
 
          8. Limited liquidity securities/securities sold under SEC Rule
     144A.  A substantial market of qualified institutional buyers may develop
     under Rule 144A of the 1933 Act for securities that are subject to legal or
     contractual restrictions on resale. If such a market develops, these
     securities may be treated as liquid securities. To the extent that for a
     period of time qualified institutional buyers cease purchasing
 
                                       A-2
<PAGE>   32
 
     such securities pursuant to Rule 144A, there may be an increase in the
     level of illiquidity in the portfolio during such period.
 
     Notwithstanding the above, it is the present intention of the Fund that the
Money Market Portfolio continue to qualify under the requirements of Rule 2a-7
of the Securities and Exchange Commission ("SEC") which permits the Portfolio to
use the amortized cost method of valuation to calculate net asset value if the
Portfolio's funds are invested in accordance with its guidelines. Briefly, those
guidelines require investment in Eligible Securities (see VALUATION OF MONEY
MARKET PORTFOLIO at page 22 for a discussion of Eligible Securities) which
qualify as First or Second Tier securities under the Rule. First Tier securities
include any Eligible Security which (i) is rated (or, if unrated, the issuer of
which also issues short-term securities any one of which, comparable in priority
and security, is rated) by an SEC designated statistical rating organization in
its highest category for short-term debt obligations, or (ii) is a security
having a remaining maturity of 397 days or less when acquired but which has an
original maturity in excess of 397 days and which is now comparable in priority
and security to a short-term security of the same issuer which is rated by an
SEC designated statistical rating organization in the highest category for
short-term debt obligations; or (iii) is unrated as a short-term security (and,
if rated as a long-term security, received a rating in one of the two highest
categories) and is issued by an issuer which has no rated short-term debt
obligations comparable in priority and security. A Second Tier security is any
Eligible Security (see VALUATION OF MONEY MARKET PORTFOLIO at page 22 for a
discussion of Eligible Securities) which is not a First Tier security.

                                    APPENDIX
 
           DESCRIPTION OF COMMERCIAL PAPER AND CORPORATE BOND RATINGS
 
Commercial Paper Ratings
 
     Moody's commercial paper ratings are opinions of the ability of issuers to
repay promissory obligations when due. Moody's employs the following three
designations, all judged to be investment grade, to indicate the relative
repayment capacity of rated issuers: Prime 1 - Superior Ability for Repayment;
Prime 2 - Strong Ability for Repayment; Prime 3 - Acceptable Ability for
Repayment.
 
     S&P's commercial paper rating is a current assessment of the likelihood of
timely payment. Ratings are graded into four categories, ranging from "A" for
the highest quality obligations to "D" for the lowest. Issues assigned the
highest rating, "A", are regarded as having the greatest capacity for timely
payment. Issues in this category are delineated with the numbers "1", "2", and
"3" to indicate the relative degree of safety. The designation "A-1" indicates
that the degree of safety regarding timely payment is either overwhelming or
very strong. The "A+" designation is applied to those issues rate "A-1" which
possess overwhelming safety characteristics. Capacity for timely payment on
issues with the designation "A-2" is strong. However, the relative degree of
safety is not as high as for issues designated "A-1."
 
     Fitch's commercial paper ratings represent Fitch's assessment of the
issuer's ability to meet its obligations in a timely manner. The assessment
places emphasis on the existence of liquidity. Ratings range from "F-1+" which
represents exceptionally strong credit quality to "F-4" which represents weak
credit quality.
 
   
     Duff's short-term ratings apply to all obligations with maturities of under
one year, including commercial paper, the uninsured portion of certificates of
deposit, unsecured bank loans, master notes, bankers acceptances, irrevocable
letters of credit and current maturities of long-term debt. Emphasis is placed
on liquidity. Issues rated Duff 1+ are regarded as having the highest certainty
of time payment. Issues rated Duff 1 are regarded as having very high certainty
of timely payment.
    
 
   
     Thomson's BankWatch, Inc. ("TBW") assigns only one Issuer Rating to each
company, based upon a qualitative and quantitative analysis of the consolidated
financials of an issuer and its subsidiaries. The rating incorporates TBW's
opinion of the vulnerability of the company to adverse developments which may
impact the marketability of its securities, as well as the issuer's ability to
repay principal and interest. Ratings range from "TBW-1" for highest quality to
"TBW-3" for the lowest, companies with very serious problems.
    
 
Bond Ratings
 
     A bond rated "Aaa" by Moody's is judged to be the best quality. They carry
the smallest degree of investment risk. Interest payments are protected by a
large or by an exceptionally stable margin and principal is deemed secure. While
the various protective elements may change, such foreseeable changes are
unlikely to impair the fundamentally strong position of such issues. 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.
Margins of protection on "Aa" bonds may not be as large as on "Aaa" securities
or fluctuations of protective elements may be of greater magnitude or there may
be other elements present which make the long-term risks appear somewhat larger
than "Aaa" securities. 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 some time in the future. Bonds rated "Baa" are considered medium
grade obligations whose interest payments and principal security appear adequate
for the present but may lack certain protective elements or may be
characteristically unreliable over any great length of time. Moody's applies
numerical modifiers "1", "2" and "3" in each generic rating classifications from
"Aa" through "B" in
 
                                       B-1
<PAGE>   34
 
its corporate bond rating system. The modifier "1" indicates that the security
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 issue
ranks in the lower end of its generic rating category. Bonds rated "Ba" are
judged to have speculative elements and bonds rated below "Ba" are speculative
to a higher degree.
 
   
     Debt rated "AAA" by S&P has the highest rating assigned by it. Capacity to
pay interest and repay principal is extremely strong. Debt rated "AA" has a
strong capacity to pay interest and repay principal and differs from "AAA"
issues only in small degree. 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. 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. Debt
rated "BB" and below is regarded as having predominantly speculative
characteristics with respect to capacity to pay interest and repay principal.
    
 
     Debt rated "AAA", the highest rating by Fitch, is considered to be of the
highest credit quality. The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events. Debt rated "AA" is regarded as very high credit quality. The
obligor's ability to pay interest and repay principal is very strong. Debt rated
"A" is of high credit quality. The obligor's ability to pay interest and repay
principal is considered to be strong, but may be more vulnerable to adverse
changes in economic conditions and circumstances than debt with higher ratings.
Debt rated "BBB" is of satisfactory credit quality. The obligor's ability to pay
interest and repay principal is adequate, however a change in economic
conditions may adversely affect timely payment. Plus (+) and minus (-) signs are
used with a rating symbol (except "AAA") to indicate the relative position
within the category.
 
     Debt rated "AAA", the highest rating by Duff is considered to be of the
highest credit quality. The risk factors are negligible being only slightly more
than for risk-free U.S. Treasury debt. Debt rated "AA" is regarded as high
credit quality. Protection factors are strong. Risk is modest but may vary
slightly from time to time because of economic conditions. Debt rated "A" is
considered to have average but adequate protection factors. Bonds rated "BBB"
are considered to have below average protection factors but still sufficient for
prudent investment. Bonds rated "BB" and below are below investment grade and
possess fluctuating protection factors and risk.

                              GENERAL INFORMATION
 
     MONY Series Fund, Inc. (the "Fund"), a Maryland corporation organized on
December 14, 1984, currently consists of seven (7) different Portfolios that
are, in effect, separate investment funds: Equity Income Portfolio, Equity
Growth Portfolio, Intermediate Term Bond Portfolio, Long Term Bond Portfolio,
Government Securities Portfolio, Money Market Portfolio, and Diversified
Portfolio (the "Portfolios"). The Fund is registered under the Investment
Company Act of 1940 (the "1940 Act") as an open-end, diversified, management
investment company. This registration does not imply any supervision by the
Securities and Exchange Commission over the Fund's management or its investment
policies or practices.
 
     For more detailed information about the Fund, including information on the
purchase, redemption and pricing of the shares of the Fund, as well as the
Fund's tax status, see the Prospectus of the Fund (STRUCTURE OF THE FUND,
PURCHASE AND REDEMPTION OF SHARES, SHARES IN THE FUND, FEDERAL INCOME TAX
STATUS).
 
                            INVESTMENT RESTRICTIONS
 
     A description of the investment objectives of each Portfolio, as well as
the policies through which those objectives are pursued, is contained in the
Prospectus (INVESTMENT OBJECTIVES AND POLICIES OF THE PORTFOLIOS).
 
     In addition, the current Portfolios of the Fund are subject to certain
fundamental investment restrictions that may not be changed except with the
approval of a majority vote of the outstanding shares of the Portfolio affected
(which for this purpose and under the 1940 Act means the lesser of (i) 67
percent of the Portfolio shares represented at a meeting at which more than 50
percent of the outstanding Portfolio shares are represented or (ii) more than 50
percent of the outstanding Portfolio shares). The Fund may in the future create
new portfolios that may be subject to different investment restrictions.
 
     The fundamental investment restrictions applicable to the seven current
Portfolios, including those fundamental restrictions described in the Prospectus
(INVESTMENT RESTRICTIONS APPLICABLE TO THE PORTFOLIOS), are:
 
          1. The Portfolios will not: (a) invest in the securities of any
     company for the purpose of exercising control or management thereof (alone
     or together with the other Portfolios); (b) write or purchase put or call
     options; (c) purchase securities on margin, except for such short-term
     credits as are necessary for the clearance of transactions, (d) effect a
     short sale of securities, or (e) invest in obligations that are not
     denominated in United States dollars.
 
          2. Securities of other issuers will not be underwritten, except that
     the right is reserved for each Portfolio to purchase for investment, on
     original issue or otherwise, securities that may not subsequently be
     distributed to the public without registration or that are exempt from
     registration, to the extent that investments in such securities will not
     exceed 10 percent of the value of each Portfolio's total assets at the time
     such an investment is made. Expenses of any such registration will be borne
     by such Portfolio only if its best efforts to have the issuer agree to bear
     such expenses are unsuccessful.
 
          3. The Portfolios will not purchase real estate or real estate
     mortgages, except that the right is reserved for each Portfolio to purchase
     and sell securities which are secured by real estate or real estate
     mortgages and securities of real estate investment trusts or other issuers
     that invest or deal in the foregoing. This restriction does not apply to
     obligations issued or guaranteed by the U.S. Government, its agencies or
     instrumentalities. This restriction does not prohibit the Fund in the
     future from establishing one or more real estate portfolios.
 
          4. The Portfolios will not purchase or sell commodities, commodity
     contracts, or oil or gas interests, except that the right is reserved for
     each Portfolio to purchase securities of issuers which invest or deal in
     the foregoing.
 
                                       (1)
<PAGE>   37
 
          5. The Portfolios will not engage in the issuance of senior
     securities, except in the case of certain borrowings, as described in
     paragraph (7) below.
 
          6. Loans, both long and short term, may be made by a Portfolio only
     through the purchase or acquisition of privately-placed bonds, debentures,
     notes or other evidences of indebtedness (that may or may not be
     convertible into stock) of a type customarily acquired by institutional
     investors provided, however, that no such purchase or acquisition will be
     made if, as a result thereof, more than 10 percent of the value of the
     Portfolio's assets would be so invested. (Any such "loan" may be considered
     a security subject to the 10 percent investment limitation referred to in
     (2) above.) The purchase or acquisition of repurchase agreements,
     certificates of deposit or of portions of publicly distributed bonds,
     debentures, or other securities, shall not be considered the making of a
     loan by the Portfolios for purposes of this restriction.
 
          7. Borrowing of money will not be made by any Portfolio, except as a
     temporary position for emergency purposes (to facilitate redemptions but
     not for leveraging or for investment) and then only from banks in an amount
     not exceeding 10 percent of the value of a Portfolio's assets (including
     the amount borrowed) less liabilities (not including the amount borrowed as
     a result of the borrowing) at the time such borrowing is made, and during
     any period when outstanding indebtedness for money borrowed shall exceed 5
     percent of the value of its total assets, the Portfolio will make no
     purchases of securities.
 
          8. In general, the Portfolios do not intend to concentrate investments
     in any one industry. Accordingly, no Portfolio will make an investment in a
     particular industry, if as a result of such investment more than 25 percent
     of the value of its assets would be invested in that industry, except that
     this restriction shall not apply to (a) obligations issued or guaranteed by
     the U.S. Government, its agencies or instrumentalities or (b) certificates
     of deposit issued by, time deposits in, bankers' acceptances accepted by,
     or repurchase agreements with, banks organized within the United States.
     For purposes of this restriction, neither finance companies as a group nor
     utility companies as a group are considered to be a single industry and
     will be grouped instead according to their services; for example, gas,
     electric, and telephone utilities will each be considered a separate
     industry.
 
          9. The Fund will operate as a diversified company as that term is used
     in the Investment Company Act of 1940. This means that 75 percent of the
     assets of each Portfolio other than the Money Market Portfolio and 100% of
     the assets of the Money Market Portfolio is subject to the limitation that
     no purchase of a security -- other than cash, cash items, and securities of
     the U.S. Government, its agencies or instrumentalities -- will be made if,
     as a result of such purchase: (a) more than 5 percent of the value of the
     Portfolio's assets would be invested in the securities of one issuer, or
     (b) the Fund as a whole or any Portfolio would hold more than 10 percent of
     the outstanding voting securities of any one issuer. In addition to the
     above limitations, the Money Market Portfolio may not have invested more
     than (x) the greater of 1 percent of its Total Assets or $1,000,000 in
     securities of any issuer, and (y) 5 percent of Total Assets in securities
     of all issuers which were, when acquired by the Portfolio (either initially
     or on rollover), Second Tier Securities (see Appendix A of the Prospectus
     for a definition of Second Tier Securities). Some uncertainty exists as to
     whether certain of the types of bank obligations in which a Portfolio may
     invest, such as certificates of deposit and bankers' acceptances, should be
     classified as "cash items" rather than "securities" for purposes of this
     restriction, which is a diversification requirement under the 1940 Act.
     Interpreting most bank obligations as "securities" limits the amount a
     Portfolio may invest in the obligations of any one bank to 5 percent of its
     total assets. If there is an authoritative decision that any of these
     obligations are not "securities" for purposes of this diversification test,
     this limitation will not apply to the purchase of such obligations.
 
          10. No Portfolio may purchase or acquire securities of other
     investment companies, except in connection with a merger, consolidation,
     acquisition or reorganization, or except by purchase in the open market of
     securities of closed-end investment companies where no underwriter's or
     dealer's commission or profit, other than customary broker's commission, is
     involved, provided that immediately thereafter such Portfolio or the Fund
     as a whole may not own (a) securities of investment companies having an
     aggregate value in excess of 10 percent of such Portfolio's total assets;
     (b) more than 3 percent of the
 
                                       (2)
<PAGE>   38
 
     outstanding voting stock of the investment company; or (c) securities of
     the investment company having an aggregate value in excess of 5 percent of
     the Portfolio's total assets.
 
          11. No Portfolio will invest more than 10 percent of its total assets
     in illiquid assets, including illiquid restricted securities, repurchase
     agreements maturing in more than seven days, and non-negotiable time
     deposits maturing in more than seven days.
 
          12. The Portfolios will not participate on a joint or a joint and
     several basis in trading accounts in securities but this restriction does
     not prevent the aggregation of orders for the sale or purchase of Portfolio
     securities with the other Portfolios or with any other accounts advised or
     sponsored by the Investment Adviser or any of its affiliates to reduce
     brokerage commissions or otherwise to achieve the best overall execution.
 
          13. No Portfolio will invest in foreign securities that are not
     publicly traded in the United States if at the time of the acquisition more
     than 10 percent of such Portfolio's total assets would be invested in such
     securities.
 
     The Money Market Portfolio is subject to the additional investment
restriction that it will not invest in any security with a remaining maturity in
excess of one year, except that underlying collateral securities held pursuant
to repurchase agreements may have a remaining maturity of more than one year.
 
                     INVESTMENT ADVISORY AND OTHER SERVICES
 
     The Fund has entered into an Investment Advisory Agreement with MONY Life
Insurance Company of America (the "Investment Adviser"), as described in the
Prospectus (INVESTMENT MANAGEMENT ARRANGEMENTS AND EXPENSES).
 
     The Investment Adviser will provide portfolio management and investment
advice to the Fund, as described in the Prospectus, with respect to the seven
current Portfolios of the Fund and any portfolio that the Fund may create in the
future if the Fund designates the Investment Adviser to act as investment
adviser and manager for such new portfolio. The Fund may, at its option, appoint
a different investment adviser for any new portfolio. The Investment Adviser
also is obligated to perform certain administrative and management services for
the Portfolios it manages and to provide all executive, administrative, clerical
and other personnel necessary to operate the Fund, and to pay the salaries of
all these persons. The Investment Adviser will furnish the Fund with office
space, facilities, and equipment and will pay the day-to-day expenses for their
operation and maintenance.
 
     The Investment Adviser has entered into a Services Agreement with The
Mutual Life Insurance Company of New York ("MONY"), as briefly described in the
Prospectus. Under this Services Agreement MONY will provide the Investment
Adviser, with some or all of the personnel, services, facilities, supplies and
equipment necessary for the Adviser to carry out its duties to the Fund. In
return the Investment Adviser will pay to MONY all, or a portion, of the
investment management fee the Investment Adviser receives from the Fund. The
Investment Adviser is a wholly-owned subsidiary of MONY, a mutual life insurance
company organized under the laws of the State of New York in 1842. MONY is
licensed to do business in all fifty states, the District of Columbia, Puerto
Rico, the Virgin Islands, and certain Canadian Provinces. Because the Investment
Advisory Agreement and Services Agreement are interrelated and dependent on each
other, MONY may be deemed to be an investment adviser to the Fund for certain
regulatory purposes. Both MONY and the Investment Adviser are registered as
investment advisers under the Investment Advisers Act of 1940.
 
   
     The Fund will pay the Investment Adviser an investment management fee,
which will be a daily charge equal to an annual rate of .50 percent of the first
$400 million of the aggregate average daily net assets of each of the Equity
Growth, Equity Income, Diversified, Intermediate Term Bond, Long Term Bond, and
Government Securities Portfolios, .35 percent of the next $400 million of the
aggregate average daily net assets of each of those Portfolios, and .30 percent
of the aggregate average daily net assets of each of those Portfolios in excess
of $800 million. The Fund will also pay a daily charge equal to an annual rate
of .40 percent of the first $400 million of the aggregate average daily net
assets of the Money Market Portfolio,
    
 
                                       (3)
<PAGE>   39
 
   
 .35 percent of the next $400 million of the aggregate average daily net assets
of the Money Market Portfolio, and .30 percent of the aggregate average daily
net assets of the Money Market Portfolio in excess of $800 million.
    
 
   
     The Investment Adviser will pay for (i) the legal, accounting, and all
other expenses of organizing the Fund, initially registering and qualifying the
Fund and its securities under federal and state securities laws (including the
costs of printing any prospectuses or other materials in connection with the
initial registration or qualification); (ii) the expense in rendering investment
advice to the Fund (including any payment to MONY as agreed to in connection
with the Services Agreement); and (iii) the compensation of directors, officers
and employees of the Fund who are interested persons (as defined by the 1940
Act) of the Investment Adviser. The Fund will bear all other expenses, including
(but without limitation): (a) legal, auditing fees and expenses; (b) interest
expenses; (c) brokerage fees and commissions; (d) the fees and expense for
computing the net asset value of the Fund's capital stock attributable to the
Portfolios; (e) taxes or governmental fees; (f) the cost of preparing share
certificates or any other direct expense of issue, sale, underwriting,
distribution, redemption or repurchase of shares of the Fund; (g) the cost of
preparing and distributing reports and notices to shareholders; (h) the cost of
holding the Fund's annual or special shareholders' meetings and of any proxy
solicitation; (i) the fees or disbursements of dividend, disbursing, plan,
transfer or other agent; (j) fees or disbursements of custodians of the Fund's
assets; (k) the compensation of all directors, officers and employees of the
Fund who are not interested persons (as defined by the 1940 Act) of the
Investment Adviser; (l) the cost of any fidelity bond for any officer, agent or
employee of the Fund required under the 1940 Act or otherwise; and (m) the cost
of any directors and officers' insurance for any directors or officers of the
Fund. The Fund will also bear the cost of maintaining the effectiveness of its
registration and qualification of its capital stock for sale (including the
preparation, printing and mailing of any prospectuses or other materials
required by federal or state authorities); these expenses will be reimbursed to
the Fund by MONY Securities Corp. ("MSC"), a wholly-owned subsidiary of MONY, as
principal underwriter, as described below in "Distribution of Shares." The Fund
will bear any extraordinary or non-recurring expenses (including expenses
associated with legal claims, liabilities, litigation costs and any related
indemnification).
    
 
     The Investment Adviser has agreed to reimburse the Fund for the amount, if
any, by which the aggregate ordinary operating expenses of any Portfolio in any
calendar year exceed the most restrictive expense limitations then in effect
under state securities law or regulations, as described in the Prospectus
(INVESTMENT MANAGEMENT ARRANGEMENTS AND EXPENSES).
 
DISTRIBUTION OF SHARES
 
   
     The Fund presently intends to offer to sell its shares continuously, on a
no-load basis, to MONY Life Insurance Company of America ("MONY America") and
MONY for allocation to MONY America Variable Account L and MONY Variable Account
L to fund benefits under Flexible Premium Variable Life Insurance Contracts
issued by those companies, and to MONY America and MONY for allocation to MONY
America Variable Account S and MONY Variable Account S to fund benefits under
Variable Life Insurance with Additional Premium Option Contracts issued by those
companies, and to MONY America and MONY for allocation to MONY America Variable
Account A and MONY Variable Account A to fund benefits under Flexible Payment
Variable Annuity Contracts issued by those companies, and to MONY for allocation
to Keynote Series Account ("Keynote") to fund benefits under Individual Variable
Annuity Contracts issued by MONY. These variable accounts ("Variable Accounts")
invest in shares of the Fund in accordance with allocation instructions received
from Contract holders. MSC will act as "principal underwriter" of the Contracts
and, therefore, of the shares of the Fund pursuant to written Underwriting
Agreements with the Fund, MONY America and MONY. The Underwriting Agreements
were initially approved by the Fund's Board of Directors, including a majority
of the non-interested directors (as defined by the 1940 Act), on December 20,
1984. Continuance of the Underwriting Agreement with the Fund, MONY and MONY
America for an additional year was most recently approved by the Fund's Board of
Directors on February 18, 1998. The agreements will continue in effect if
approved annually by the Fund's Board of Directors, including a majority of the
non-interested directors. MSC will not receive commissions or other compensation
for acting as principal underwriter of the Fund's shares, although MSC's agents
and
    
 
                                       (4)
<PAGE>   40
 
representatives may receive sales commissions in connection with their sale of
the Contracts. Since shares will be sold only to MONY and MONY America for
allocation to the Variable Accounts, and to MONY in respect of its providing
operating capital to the Fund, it is expected that the Fund will have no
distribution expenses other than the expense of the preparation, printing and
mailing of prospectuses. MONY has agreed to bear such start-up expenses, as well
as any other distribution expenses that may arise.
 
     MSC, as broker-dealer for the Contracts, will be reimbursed by MONY and
MONY America for these distribution expenses. If the Fund in the future is to
bear any of these distribution expenses, the Fund's Board of Directors will
formulate a written distribution plan that complies with the rules of the
Securities and Exchange Commission. Both this distribution plan and any
distribution agreement entered into pursuant to the plan will be approved by the
Fund's Board of Directors, including a majority of the non-interested directors
(as defined by the 1940 Act). The plan will then be submitted for approval at
the next annual meeting of shareholders. Thereafter, both the distribution plan
and any related distribution agreement will continue in effect if approved
annually by a majority of the Fund's Board of Directors, including a majority of
the non-interested directors (as defined by the 1940 Act).

SERVICE MARKS LICENSE
 
     As part of the Investment Advisory Agreement, the Investment Adviser
(acting on behalf of MONY) has granted the Fund permission to use the word
"MONY" in its corporate name and granted a royalty-free, non-exclusive license
to use any service marks adopted by MONY that are appropriate for use by the
Fund. However, the Investment Adviser may terminate this license if MONY, or a
company controlled by it, ceases to be the Fund's investment adviser. The
Investment Adviser may also terminate the license for any other reason upon 60
days' written notice. In this event, the Fund would no longer be able to use the
word "MONY" in its corporate name. In addition, the Investment Advisory
Agreement would also terminate 120 days after the Fund receives such notice,
unless a majority of the outstanding voting shares of the Fund vote to continue
the Agreement notwithstanding the license's termination.

* Mr. Levine, who is an interested person (as that term is defined in the 1940
  Act), is a salaried employee of MONY.
 
     No director or officer of the Fund who is also an officer, director or
employee of MONY or MONY America is entitled to any additional remuneration from
the Fund for his services as one of its directors or officers. Each director of
the Fund who is not an interested person of the Fund will receive a fee of
$1,750 per calendar quarter plus an additional amount of $1,000 for each meeting
of the Board, of a Committee of the Board (as provided for in the By-Laws), or
of the Fund's shareholders that he attends. Non-interested directors will also
be reimbursed for all expenses incurred in connection with attendance at
meetings.
 
     The 1940 Act requires that a majority of the Fund's Board of Directors
shall be persons who are not interested persons of MONY, the Investment Adviser
or the Fund. The membership of the Board complies with this requirement. Certain
actions of the Board, including the annual continuance of the Investment
Advisory Agreement between the Fund and the Investment Adviser and the Services
Agreement between the Investment Adviser and MONY, must be approved by a
majority of the members of the Board who are not interested persons of MONY, the
Investment Adviser or the Fund. One of the five members of the Board, Mr. Levine
is an interested person of MONY, the Investment Adviser and the Fund (as that
term is defined in the 1940 Act) because he is an affiliated person of MONY and
the Investment Adviser.
 
                           SUBSEQUENT ANNUAL MEETINGS
 
   
     The Board of Directors of the Fund has amended the By-laws of the Fund to
provide that annual meetings will not be held in any year unless the Investment
Company Act of 1940 (the "1940 Act") requires action on one or more of the
following matters: (1) election of directors; (2) approval of investment
advisory agreement; and (3) ratification of selection of independent public
accountants; and (4) approval of a distribution agreement. The 1940 Act
essentially requires election of directors by shareholders when less than a
majority then in office had been elected by shareholders, and it requires
ratification of the selection of independent public accountants when the
selection of such accountants has not previously been ratified by the
shareholders. It also requires approval of an agreement with an investment
advisor when such agreement has not previously been approved by the shareholders
(other than an agreement with an investment adviser entered into when a new
portfolio of the Fund is created). Currently, the 1940 Act requires a
distribution agreement to be approved by either the board of directors or the
shareholders.

                                CONTROL PERSONS
 
     MONY America, a wholly-owned subsidiary of MONY, and MONY through their
respective Variable Accounts will own all of the Fund's outstanding shares,
other than the shares in the Fund purchased for investment by MONY to provide
operating capital for the Portfolios (and any new portfolios) of the Fund
started and any additional shares acquired by MONY through reinvestment of
dividends on those shares. The shares held by the Variable Accounts will
generally be voted in accordance with instructions of Contract holders. Under
certain circumstances, however, MONY and MONY America may disregard voting
instructions received from Contract holders. The shares held by MONY in respect
of its providing operating capital to the Fund's Portfolios will be voted in the
same proportions as those voted by MONY and MONY America which are held in the
Variable Accounts. The Fund might nonetheless be deemed to be controlled by MONY
and MONY America by virtue of the definitions contained in the 1940 Act although
the Fund disclaims such control. The amount of shares of each Portfolio of the
Fund owned by directors or officers of the Fund will therefore be less than one
percent.
 
                   PORTFOLIO BROKERAGE AND RELATED PRACTICES
 
     The Investment Adviser, which is at all times subject to the direction and
supervision of the Board of Directors of the Fund, is responsible for decisions
to buy and sell securities for the Portfolios, the selection of brokers and
dealers to effect the transactions, and the negotiations of brokerage
commissions, if any. The Investment Adviser may fulfill these responsibilities
to the Fund by using the services of MONY and MONY's Investment Department
personnel under the terms of the Services Agreement between the Investment
Adviser and MONY. For more detailed information about the Services Agreement,
see INVESTMENT ADVISORY AND OTHER SERVICES at pages 3-5.
 
     Transactions on a stock exchange in equity securities will be executed
primarily through brokers that will receive a commission paid by the Fund.
Transactions in money market instruments and bonds, on the other hand, will not
normally incur any brokerage commissions. Such securities, as well as equity
securities traded in the over-the-counter market, are generally traded on a
"net" basis with dealers acting as principals for their own accounts without a
stated commission, although the price of a security usually includes a profit to
the dealer. In underwritten offerings, securities are purchased at a fixed price
that includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. Certain of these securities may
also be purchased directly from an issuer, in which case neither commissions nor
discounts are paid.
 
   
     The Investment Adviser is not obligated to deal with any dealer or group of
dealers in the execution of transactions for the Fund's Portfolios. In
connection with any securities transaction that involves a commission payment,
the Investment Adviser negotiates the commission with the broker in part on the
basis of the quality and quantity of execution services that the broker
provides, in light of generally prevailing commission rates. For the years 1995,
1996, and 1997, the Fund paid $22,126, $17,005, and $18,634, respectively, in
brokerage commissions.
    
 
     When selecting a broker or dealer in connection with a transaction for any
Portfolio, the Investment Adviser gives consideration to whether the broker or
dealer has furnished MONY or any companies controlled by MONY with certain
research services. These services, which include statistical and economic data
and research reports on particular companies and industries, are services that
brokerage houses customarily provide to institutional investors. MONY personnel
may use these services in connection with all of the investment activities of
MONY or its companies, and some of the data or services obtained in connection
with the execution of transactions for a Portfolio may be used in managing other
investment accounts of MONY or its companies. Conversely, brokers and dealers
furnishing such services may be selected for the execution of transactions of
such other accounts, while the data or service may be used by MONY personnel in
providing investment management for the Fund.
 
     It is the present practice of the Investment Adviser to use brokers
selected primarily on the basis of their furnishing not only satisfactory
execution of the transaction but also research services such as analyses and
 
                                       (9)
<PAGE>   45
 
reports concerning issuers and industries, economic factors and portfolio
strategy. In some cases, this could cause the Fund to pay commissions or spreads
in excess of the amount which another broker would have charged for effecting a
similar transaction. In any such case, the Investment Adviser will determine in
good faith that the greater commission or spread is reasonable in relation to
the value of the services provided by the executing broker viewed in terms of
the particular transaction or the Investment Adviser's responsibilities to each
Portfolio and overall responsibilities to all the Portfolios of the Fund and
accounts under the Investment Adviser's and MONY's management. No services other
than brokerage, research and statistical services are considered by the
Investment Adviser in determining the reasonableness and amount of commissions
or spreads to be paid to any broker. All such services obtained from brokers
benefit generally all the accounts and Portfolios under the Investment Adviser's
management and are not identified in any specific account or Portfolio, and may
benefit other accounts under MONY's management. Information so received will be
in addition to and not in lieu of the services required to be performed by the
Investment Adviser.
 
     The Investment Adviser may employ a broker affiliated with the Investment
Adviser or MONY to execute brokerage transactions on behalf of the Portfolios,
as long as the Investment Adviser obtains a price and execution as favorable as
that which would be available through the use of an unaffiliated broker, and no
less favorable than the affiliated broker's contemporaneous charges to its other
most favored, but unaffiliated, customers. The Fund may not engage in any
transactions in which MONY or any of its affiliates acts as principal, including
over-the-counter purchases and negotiated trades in which such a party acts as a
principal.
 
     The Investment Adviser or MONY may enter into business transactions with
brokers or dealers other than using them to execute Portfolio securities
transactions for accounts the Investment Adviser manages. These other
transactions will not affect the Investment Adviser's selection of brokers or
dealers in connection with portfolio transactions for the Fund.
 
   
     The portfolio turnover rates for each Portfolio of the Fund are shown on
pages 4-10 of the Prospectus.
    
 
                           FEDERAL INCOME TAX STATUS
 
     The Fund and each of its portfolios intend to qualify as a "regulated
investment company" under the applicable provisions of the Internal Revenue Code
of 1986, as amended (the "Code"). To qualify for treatment as a regulated
investment company, the Fund must meet certain requirements specified in the
Code as described in the Prospectus ("Federal Income Tax Status"). If the Fund
qualifies as a "regulated investment company" by complying with applicable
provisions of the Code and distributes all of its net income (both ordinary
income and capital gain), the Fund will be relieved of federal income tax on the
amounts distributed.
 
     The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations currently in effect as
interpreted by the courts and the Internal Revenue Service. For the complete
provisions, reference should be made to the pertinent Code sections and the
Treasury Regulations promulgated thereunder. The Code and these Regulations are
subject to change by legislative, administrative or judicial action. Moreover,
although "series" fund regulated investment companies have been in existence for
many years, there is very little authority interpreting the pertinent provisions
of the Code and Treasury Regulations as they are applied to a "series" fund type
of regulated investment company like the Fund.
 
                                PERFORMANCE DATA
 
   
     Money Market Portfolio.  For the seven day period ended December 31, 1997,
the yield was 5.29% and the effective yield was 5.43%.
    
 
     The yield was calculated by dividing the sum of dividends declared during
the 7 day period on one share purchased at the beginning of the 7 day period by
the value on the first day (the resulting quotient being the
 
                                      (10)
<PAGE>   46
 
"Base Period Return") and multiplying the Base Period Return by 365 divided by 7
to obtain the annualized yield.
 
     The effective yield was calculated by compounding the Base Period Return
calculated in accordance with the preceding paragraph, adding 1 to the Base
Period Return, raising that sum to a power equal to 365 divided by 7 and
subtracting 1 from the result.
 
     Dividends reflect the net investment income of the Portfolio. Net
investment income reflects earnings on investments less expenses of the Fund
including the Investment Management Fee (which for calculating the yield and
effective yield quoted above will be the fee which would be charged based upon
the amount of assets under management on the last day of the period for which
the quoted yield is stated, which for the yield and the effective yield quoted
above is .40%). It is the practice of the Money Market Portfolio to pay
dividends daily in the form of shares (thereby maintaining the value of one
share of the Money Market Portfolio at $1.00). However, for the purpose of these
calculations, it has been assumed that no additional shares have been issued and
that dividends are paid in cash.
 
   
     All Portfolios including the Money Market Portfolio.  The average annual
total return for the one, five, and ten year periods ended December 31, 1997,
and for the period since inception through December 31, 1997, are shown in the
following table.

     The yield shown in the table above is computed by subtracting from the net
investment income of the Portfolio of the Fund charges and expenses of the Fund
with respect to the Portfolio and dividing the result by the value of the
Portfolio. For the Equity Growth and Equity Income Portfolios and for the stocks
and equity securities of the Diversified Portfolio of the Fund, net investment
income is the net of the dividends accrued ( 1/360 of the stated dividend rate
multiplied by the number of days the particular security is in the Portfolio) on
all equity securities during the 30-day period and expenses accrued for the
period. It does not reflect capital gains or losses. For the Intermediate Term
Bond, Long Term Bond and the Government Securities Portfolios and the debt
obligations held by the Diversified Portfolio of the Fund, net investment income
is the net of interest earned on the obligation held by the Portfolio and
expenses accrued for the period. Interest earned on the obligation is determined
by (i) computing the yield to maturity based on the market value of each
obligation held in the corresponding Portfolio at the close of business on the
thirtieth day of the period (or as to obligations purchased during that 30-day
period, based on the purchase price plus accrued interest); (ii) dividing the
yield to maturity for each obligation by 360; (iii) multiplying that quotient by
the market value of each obligation (including actual accrued interest) for each
day of the subsequent 30-day month that the obligation is in the Portfolio; and
(iv) totaling the interest on each obligation. Discount or premium amortization
is recomputed at the beginning of each 30-day period and with respect to
discount and premium on mortgage or other receivables-backed obligations subject
to monthly payment of principal and interest, discount and premium is amortized
on the remaining security, based on the cost of the security, to the weighted
average maturity date, if available, or to the remaining term of the security,
if the weighted average maturity date is not available. Gain or loss
attributable to actual monthly paydowns is reflected as an increase or decrease
in interest income during that period.
 
     The yield shown reflects deductions for all charges, expenses, and fees of
the Fund. The table does not reflect charges and deductions which are, or may
be, imposed under the Contracts.
 
     Net investment income of the Portfolio less all charges and expenses of the
Fund with respect to the Portfolio is divided by the product of the average
daily number of shares outstanding and the net asset value of one share on the
last day of the period. The sum of the quotient and 1 is raised to the 6th
power, 1 is subtracted from the result, and then multiplied by 2.

                         NOTES TO FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
     The MONY Series Fund, Inc. (the "Fund"), a Maryland corporation organized
on December 14, 1984, is composed of seven different portfolios that are, in
effect, separate investment funds: the Equity Growth Portfolio, the Equity
Income Portfolio, the Intermediate Term Bond Portfolio, the Long Term Bond
Portfolio, the Diversified Portfolio, the Government Securities Portfolio, and
the Money Market Portfolio. The Fund issues a separate class of capital stock
for each portfolio. Each share of capital stock issued with respect to a
portfolio will have a pro-rata interest in the assets of that portfolio and will
have no interest in the assets of any other portfolio. Each portfolio bears its
own liabilities and also its proportionate share of the general liabilities of
the Fund. The Fund is registered under the Investment Company Act of 1940 (the
"1940 Act") as an open-end, diversified, management investment company. This
registration does not imply any supervision by the Securities and Exchange
Commission over the Fund's management.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
  A. Portfolio Valuations:
 
     Short-term securities with 61 days or more to maturity at time of purchase
are valued at market through the 61st day prior to maturity, based on quotations
obtained from market makers or other appropriate sources; thereafter, any
unrealized appreciation or depreciation existing on the 61st day is amortized on
a straight-line basis over the remaining number of days to maturity. Short-term
securities with 60 days or less to maturity at time of purchase are valued at
amortized cost. The amortized cost of a security is determined by valuing it at
original cost and thereafter amortizing any discount or premium at a constant
rate until maturity. Securities in the Money Market Portfolio are valued at
amortized cost.
 
     Common stocks traded on national securities exchanges are valued at the
last sales price as of the close of the New York Stock Exchange or at the last
bid price for over-the-counter securities.
 
     Bonds are valued at the last available price provided by an independent
pricing service for securities traded on a national securities exchange. Bonds
that are listed on a national securities exchange but are not traded and bonds
that are regularly traded in the over-the-counter market are valued at the mean
of the last available bid and asked prices provided by an independent pricing
service.
 
     Original issue discounts on investments purchased are amortized over their
respective lives using the yield-to-maturity method.
 
     All other securities, when held by the Fund, including any restricted
securities, are valued at their fair value as determined in good faith by the
Board of Directors. As of December 31, 1997 there were no such securities.
 
  B. Federal Income Taxes:
 
     Each portfolio of the Fund is a separate entity for Federal income tax
purposes and intends to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and to distribute all of its
taxable income to its shareholders. Therefore, no Federal income tax provision
is required.
 
  C. Security Transactions and Investment Income:
 
     Security transactions are recorded as of the trade date.
 
     Dividend income is recorded on the ex-dividend date, income from other
investments is accrued as earned.
 
     Realized gains and losses from investments sold are determined on the basis
of identified cost for accounting and federal income tax purposes.
 
  D. Other:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and

liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from these estimates.
 
     Earnings credits received from the custodian are shown as a reduction of
total expenses.
 
3. INVESTMENT ADVISORY FEES AND RELATED PARTY TRANSACTIONS
 
     Under an investment advisory agreement between the Fund and MONY Life
Insurance Company of America ("Investment Adviser" or "MONY America"), a
wholly-owned subsidiary of The Mutual Life Insurance Company of New York
("MONY"), the Investment Adviser provides investment advice and related services
for each of the Fund's portfolios, administers the overall day-to-day affairs of
the Fund, bears all expenses associated with organizing the Fund, the initial
registration of its securities, and the compensation of the directors, officers
and employees of the Fund who are affiliated with the Investment Adviser.
 
     For these services, the Investment Adviser receives an investment advisory
fee and an accounting fee. The investment advisory fee is a daily charge equal
to an annual rate of .50% of the first $400,000,000 of the average daily net
assets of each of the Fund's Portfolios except the Money Market Portfolio, which
is .40% of the first $400,000,000 of the average daily net assets, .35% of the
next $400,000,000 of the average daily net assets of each of the Fund's
Portfolios; and .30% of the average daily net assets of each of the Fund's
Portfolios in excess of $800,000,000. Prior to October 14, 1997, the investment
advisory fee for the first $400,000,000 was .40% of the aggregate average daily
net assets for all of the Fund's Portfolios. For the year ended December 31,
1997, the fees incurred by the Fund were $1,265,983. On October 15, 1997, the
Investment Adviser began assessing the Fund an accounting fee. This fee is based
on an allocation of expenses borne by the Investment Adviser for personnel,
facilities and services necessary to calculate the Portfolios' daily net asset
values. The fee is allocated to the Portfolios at $25,000 per portfolio, per
annum, with the excess of the Investment Adviser's expenses allocated to each
Portfolio daily based on each Portfolio's net assets in relation to the total
net assets of the Fund.
 
     The Investment Adviser has a service agreement with MONY to provide it with
personnel, services, facilities, supplies and equipment in order to carry out
its duties to provide investment management services under the Investment
Advisory Agreement. MONY also provides transfer agent services to the Fund. The
Investment Adviser pays MONY for these services.
 
     Aggregate remuneration incurred to non-affiliated Directors of the Fund for
the year ended December 31, 1997, amounted to $47,998.
 
4. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS
 
     Dividends and distributions to shareholders are recorded on the ex-dividend
date. Dividends from net investment income (including realized gains and losses
on portfolio securities) of the Money Market Portfolio are declared and
reinvested each business day in additional full and fractional shares of the
portfolio. This policy enables the Money Market Portfolio to maintain a net
asset value of $1.00 per share.
 
     Dividends from net investment income and net realized capital gains of the
other portfolios will normally be declared and reinvested annually in additional
full and fractional shares.
 
     Dividends from net investment income and distributions from net realized
capital gains are determined in accordance with U.S. federal income tax
regulations which may differ from generally accepted accounting principles.
 
     During the year ended December 31, 1997, the Equity Income Portfolio
increased undistributed realized gains by $5,354 and decreased undistributed net
investment income by $5,354. These differences are primarily due to return of
capital distributions received on investments.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
MONY Series Fund, Inc.:
 
     We have audited the accompanying statements of assets and liabilities of
MONY Series Fund, Inc. (comprising the Equity Growth, Equity Income,
Intermediate Term Bond, Long Term Bond, Diversified, Government Securities and
Money Market Portfolios), including the portfolios of investments, as of
December 31, 1997, the related statements of operations for the year then ended,
the statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the ten years in the period
then ended for all the Portfolios except Government Securities Portfolio for
which the period is for each of the six years in the period ended December 31,
1997 and for the period from May 1, 1991 (commencement of operations) to
December 31, 1991. These financial statements are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. Our procedures included
confirmation of securities owned as of December 31, 1997, by correspondence with
the custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
each of the respective portfolios constituting the MONY Series Fund, Inc. as of
December 31, 1997, the results of their operations for the year then ended, the
changes in their net assets for each of the two years in the period then ended,
and the financial highlights for each of the periods referred to above, in
conformity with generally accepted accounting principles.

and Statement of Additional Information (Control Persons). Those shares will be
voted as directed by persons having interests in the respective Variable

ITEM 27.  INDEMNIFICATION
 
     Article VII, paragraph (4) of Registrant's Articles of Incorporation
provides that:
 
          The Corporation shall have the power and authority to indemnify its
     directors, officers and employees to the fullest extent permitted by law.
     No provision of these Articles of Incorporation shall be effective to (a)
     require a waiver of compliance with any provision of the Securities Act of
     1933, as amended, or the Investment Company Act of 1940, as amended, or of
     any valid rule, regulation or order of the Securities and Exchange
     Commission thereunder or (b) protect or purport to protect any director or
     officer of the Corporation against any liability to the Corporation or its
     security holders to which he or she would otherwise be subject by reason of
     willful misfeasance, bad faith, gross negligence or reckless disregard of
     the duties involved in the conduct of his or her office.
 
     Article VIII of the Registrant's By-Laws provides that:
 
          Each officer, director, employee or agent of the Corporation shall be
     indemnified by the Corporation to the fullest extent permitted under the
     Maryland General Corporation Law and the Investment Company Act of 1940, as
     amended. Nothing in the By-Laws protects or purports to protect any
     director, officer, employee, or agent of the Corporation against any
     liability to the Corporation or its shareholders to which he or she would
     otherwise be subject by reason of willful misfeasance, bad faith, gross
     negligence or reckless disregard of the duties involved in the conduct of
     his or her office.
 
     Article V of the Investment Advisory Agreement between Registrant and MONY

          The Adviser will not be liable for any error of judgment or mistake of
     law or for any loss suffered by the Fund in connection with the investment
     management services it performs under this Agreement, except for a loss
     resulting from willful misfeasance, bad faith, or gross negligence or
     reckless disregard in the performance of the duties or obligations under
     this Agreement of Adviser (or its officers, directors, agents, employees,
     controlling persons, shareholders, or any other person or entity affiliated
     with the Adviser or retained by it to perform or assist in the performance
     of its obligations under this Agreement). With respect to the
     administrative services it is obligated to perform under this Agreement,
     the Adviser will not be liable for any action taken or omitted by it in
     good faith without negligence.
 
   
     The MONY Directors' and Officers' Liability and Corporate Reimbursement
Insurance Policies, provide coverage for "Loss" (as defined in the Policies)
arising from any claim or claims by reason of any breach of duty, actual or
alleged error or misstatement or misleading statement, or net or omission or
neglect or breach of duty by a director or officer of MONY, any of its
subsidiaries, or investment companies affiliated with MONY (including the
Registrant), or any matter (not excluded by the coverage) claimed against him
solely by reason of his being a director or officer. The coverage Corporate
Reimbursement is provided to these insureds to the extent they shall be required
or permitted according to applicable law, common or statutory, or under their
respective charters or by-laws, to indemnify directors or officers for loss
arising from the above-described matters. Coverage is also provided to the
individual directors or officers for such loss, to the extent that they shall
not be indemnified. Loss essentially is the legal liability on claims against a
director or officer, including damages, judgments, settlements, costs, costs of
investigation (excluding salaries of officers or employees), amounts incurred in
the defense of legal actions, claims or proceedings and appeals therefrom and
cost of attachment or similar bonds. There are a number of exclusions from
coverage. One of the policies was issued by the Sargasso Mutual Insurance
Company, Ltd. and provides coverage for both Corporate Reimbursement and
Individual Reimbursement. The aggregate limit of coverage under the policies is
$15,000,000 each policy year, the corporate retention is $1,000,000 per loss,
and retention per person is $5,000 with an aggregate retention of $50,000 for
all persons per loss. After the retention limits are satisfied, the coverage
pays 99.5 percent of covered loss up to $1,000,000, and 100 percent of covered
loss in excess of $1,000,000. In addition, policies were issued by Corporate
Officers and Directors Assurance, Ltd. and ACE Insurance, Ltd. providing
Individual Reimbursement coverage as excess over the Sargasso policy with limits
of $10,000,000 and $25,000,000, respectively.

     (b) Not Applicable.
 
     (c) Subject to the terms and conditions of Section 15(d) of the Securities
Exchange Act of 1934, the undersigned Registrant hereby undertakes to file with
the Securities and Exchange Commission such supplementary and periodic
information, documents and reports as may be prescribed by any rule or
regulation of the Commission heretofore or hereafter duly adopted pursuant to
authority conferred in that Section.
 
     Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant, pursuant to the provisions of its By-Laws and the laws of Maryland
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 said 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 paid or incurred by a director, officer or
controlling person in the successful defense
 
                                      II-6

of any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, and the
Commission is still of the same opinion, 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 of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                          INVESTMENT ADVISORY AGREEMENT


         This amended INVESTMENT ADVISORY AGREEMENT (the "Agreement") made as of
the 4th day of August, 1997, by and between MONY SERIES FUND, INC. (the "Fund"),
a Maryland corporation, and MONY LIFE INSURANCE COMPANY OF AMERICA (the
"Adviser"), an Arizona corporation.


                              W I T N E S S E T H:

         WHEREAS, the Fund is an open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act");

         WHEREAS, the Adviser is registered as an investment adviser under the
Investment Advisers Act of 1940;

         WHEREAS, the Fund desires to retain the Adviser to render investment
management services to the Fund in the manner and on the terms and conditions
set forth herein;

         NOW, THEREFORE, for and in consideration of the premises and the mutual
promises set forth herein, the parties hereto agree as follows:


                                    ARTICLE I
                              DUTIES OF THE ADVISER

         The Fund hereby employs the Adviser to act as the investment adviser to
and manager of the Fund and, subject to the supervision of the Board of
Directors of the Fund (the "Board"), to manage the investment and reinvestment
of the assets of the Equity Income Portfolio, Long Term Bond Portfolio,
Intermediate Term Bond Portfolio, Equity Growth Portfolio, Money Market
Portfolio, Government Securities and Diversified Portfolio, as well as any other
portfolio that the Fund may create in the future if the Fund (at its option and
in its sole discretion) designates the Adviser to act as investment adviser and
manager for such new portfolio. The portfolios for which the Adviser acts as
investment adviser and manager under this Agreement are referred to in this
Agreement as the "Portfolios". The Adviser hereby accepts such employment and
agrees during such period, at its own expense, to render the services and to
assume the obligations herein set forth for the compensation provided for
herein. Nothing in this Agreement shall be deemed to require the Fund to take
any action contrary to its Articles of Incorporation, By-Laws, or any applicable
statute or regulation, or to relieve the Fund's Board of Directors of its
responsibility for and control of the conduct of the affairs of the Fund. The
Adviser shall be deemed for all purposes under this Agreement to be an
independent contractor and shall, unless otherwise expressly authorized or
provided herein, have no authority to act for or represent the Fund in any way
or otherwise be deemed to be an agent of the Fund.

1.       Investment Management Services

                  Subject to the Board's direction and approval, the Adviser
         shall at its own expense supervise and manage the investment and
         reinvestment of the assets of the Portfolios and shall determine the
         composition of the assets of each of the Fund's Portfolios, including
         the purchase, retention, or sale of the securities and cash contained
         in those Portfolios. These duties shall be performed in accordance with
         the 1940 Act and the investment objectives, policies and restrictions
         applicable to each Portfolio as stated in (i) the Fund's current
         Registration Statement and Prospectus filed with the Securities and
         Exchange Commission, (ii) the Fund's Articles of Incorporation and
         By-Laws, as amended from time to time, and (iii) resolutions adopted by
         the Board.

                  The Adviser shall at its own expense provide investment
         research and conduct a continuous program of evaluation, investment,
         sales, and reinvestment of the Fund's assets by recommending which
         securities should be purchased, sold or exchanged for each Portfolio,
         when these transactions should be executed, and what portion of the
         assets of each Portfolio should be held in the various securities in
         which it may invest. The Adviser will determine the daily net asset
         value of the shares of capital stock related to each Portfolio of the
         Fund as required by applicable law.

                  The Adviser shall exercise its best judgment in performing the
         services described above.

2.       Reports And Administration Services

         a.       Reports

                           Adviser shall at its own expense furnish the Fund
                  with statistical information and records concerning its
                  investments, and with such periodic or special reports as the
                  Fund's Board of Directors may from time to time reasonably
                  request, or as the Adviser may deem helpful to the Fund in the
                  administration of its Portfolios. In addition, the Adviser
                  shall at its own expense preserve for the period prescribed by
                  the rules and regulations of the Securities and Exchange
                  Commission all such records required to be maintained under
                  such rules and regulations. The Adviser shall at its own
                  expense furnish applicable federal and state regulatory
                  authorities with any information or reports in connection with
                  its services under this Agreement which such authorities may
                  request.

                           All records maintained by the Adviser in connection
                  with this Agreement shall be the property of the Fund and
                  shall be returned to the Fund upon termination of this
                  Agreement, free from any claims or retention of rights by the
                  Adviser. The Adviser shall keep confidential any information
                  obtained pursuant to this Agreement and shall disclose such
                  information only if the Fund has authorized such disclosure,
                  or if such disclosure is expressly required by applicable
                  federal or state regulatory authorities.


                                      -2-
<PAGE>   3

         b.       Administrative Services

                           The Adviser shall at its own expense also perform
                  administrative services for the Fund. Such services shall
                  include, without limitation, (i) supervising all aspects of
                  the Fund's operation, including coordinating matters relating
                  to the custodians of securities owned by the Fund, the
                  transfer agent, shareholder service agents, accountants,
                  attorneys, and other parties performing services or
                  operational functions for the Fund, (ii) providing personnel
                  to the Fund to perform necessary administrative functions, and
                  (iii) providing the Fund with adequate and appropriate office
                  space, facilities, equipment and related services necessary
                  for the Fund's operations. Nothing contained herein shall
                  restrict the Fund's ability to hire its own employees or to
                  contract for services to be performed by third parties.

3.       Services Agreement

                  It is contemplated that contemporaneously with this Agreement
         the Adviser will enter into a Services Agreement with The Mutual Life
         Insurance Company of New York ("MONY") under which MONY would provide
         to the Adviser some or all of the personnel, services, facilities,
         supplies and equipment necessary for the Adviser to carry out its
         obligations under this Agreement. It is recognized that said Services
         Agreement will be deemed a sub-advisory agreement subject to the
         pertinent provisions of the 1940 Act. No rights or obligations of the
         Adviser under this Agreement shall be deemed to have been assigned or
         otherwise transferred by virtue of said Services Agreement, and said
         Services Agreement shall automatically terminate upon its assignment by
         either party thereto.


                                   ARTICLE II
                      PORTFOLIO TRANSACTIONS AND BROKERAGE

         Subject to the limitation of Article I, the Adviser shall determine all
securities to be bought or sold for each Portfolio, and shall be responsible for
the selection of brokers or dealers to effect all transactions. The Adviser
shall place all necessary orders with brokers, dealers, or issuers, and shall
negotiate brokerage commissions, if applicable. In placing orders for securities
transactions, the Adviser shall attempt to obtain the best net price and most
favorable execution. The Adviser will seek to effect each transaction at a price
and commission, if any, that provides the most favorable total cost or proceeds
reasonably attainable in the circumstances. The Adviser may, however, pay a
higher spread or commission than otherwise would be necessary for a particular
transaction if that would further the goal of obtaining the best available
execution.

         For those securities transactions that involve commission payments, the
Adviser will negotiate the commission on the basis of the quality and quantity
of execution services provided by the broker, in light of generally prevailing
commission rates. It is the Adviser's present


                                      -3-
<PAGE>   4

practice to use brokers selected primarily on the basis of their furnishing not
only satisfactory execution of the transaction but also research services such
as analyses and reports concerning issuers and industries, economic factors and
portfolio strategy. In some cases, this could cause the Fund to pay commissions
or spreads in excess of the amount which another broker would have charged for
effecting a similar transaction. In any such case, the Adviser shall determine
in good faith that the greater commission or spread is reasonable in relation to
the value of the services provided by the executing broker/dealer viewed in
terms of either the particular transaction or the Adviser's overall
responsibilities to all the Portfolios of the Fund and accounts under the
Adviser's management. No services other than brokerage, research and statistical
services are considered by the Adviser in determining the reasonableness and
amount of commissions or spreads to be paid to any broker/dealer. All such
services obtained from brokers benefit generally all the Portfolios and accounts
under the Adviser's management and are not identified in any specific Portfolio
or account and may also benefit other accounts under MONY's management. The Fund
agrees that MONY, or the Adviser, may use any such research or statistical
information that the Adviser obtains from brokers in providing investment
management or advice to their other clients and accounts.

         In executing brokerage transactions, the Adviser may use a broker who
is an affiliated person of the Adviser (as that term is defined in the 1940
Act), only if the commission rate obtained from the affiliated broker is as
favorable as the broker's contemporaneous charges to its most favored
unaffiliated customers. Before employing an affiliated broker, Adviser must also
make the good faith judgment that the affiliated broker is qualified to obtain
the best price on the particular transaction and that the commission is at least
as favorable as that charged by other qualified, but unaffiliated, brokers.


                                   ARTICLE III
                            ACTIVITIES OF THE ADVISER

         The Fund understands that the Adviser and the sub-adviser, MONY, may
serve as investment manager or adviser to other investment companies and to
clients that are not investment companies. The Adviser may also perform similar
functions in managing its own assets, and MONY performs similar functions in
managing its own assets, the assets of its separate accounts, and the assets of
certain of its subsidiaries. The Fund understands that the employees of MONY who
will assist in the performance of services for the Adviser under the Services
Agreement referred to in Article I will also devote time to rendering similar
services to the other entities for which MONY also acts as investment manager or
adviser. When investment opportunities arise that may be appropriate for more
than one account, fund, or company for which MONY provides investment management
services, such Services Agreement shall provide that MONY will not favor one
over another and may allocate investments among them in an impartial manner
believed to be equitable to each entity involved. The allocations will be based
on each entity's investment objectives and its current cash and investment
positions. Because the various entities for which MONY provides investment
management services, including for its own account, have different investment
objectives and policies, MONY personnel acting on behalf of such entities may
from time to time buy a particular


                                      -4-
<PAGE>   5

security of one or more such entities while at the same time selling such
securities for another entity.


                                   ARTICLE IV
                           COMPENSATION OF THE ADVISER

1.       Investment Management Fee

                  As compensation for the services and expenses of the Adviser
         under this Agreement, the Fund shall pay to the Adviser an investment
         management fee subject to the limitations of paragraph 3 of this
         Article IV. For the Equity Income, Equity Growth, Diversified,
         Intermediate Term Bond, Long Term Bond and Government Securities
         Portfolios, this fee shall be a daily charge, payable at the end of
         each calendar month, at an annual rate of .50 percent of the first $400
         million of the average daily net assets of each Portfolio, .35 percent
         of the next $400 million of the average daily net assets of each
         Portfolio, and .30 percent of the average daily net assets of each
         Portfolio in excess of $800 million. For the Money Market Portfolio,
         this fee shall be a daily charge, payable at the end of each calendar
         month, at an annual rate of .40 percent of the first $400 million of
         the average daily net assets of the Portfolio, .35 percent of the next
         $400 million of the average daily net assets of the Portfolio, and .30
         percent of the average daily net assets of the Portfolio in excess of
         $800 million. The daily charge for each Portfolio shall be based on the
         average daily net assets of the applicable Fund's Portfolio, whether or
         not the net assets of each Portfolio are valued on such day.

                  The manner of computing net asset value shall be determined by
         the Board of Directors of the Fund.

2.       Allocation of Expenses

                  The Adviser will bear only the following: (i) the expenses
         (including legal and accounting expenses) for the organization of the
         Fund, the Fund's initial registration under federal and state
         securities laws, and the initial registration and qualification of the

         prospectuses or other materials in connection with the initial
         registration or qualification); (ii) the expenses in rendering
         investment advice and performing administrative and other services

         directors, officers and employees of the Fund who are interested
         persons (as defined in the 1940 Act) of the Adviser except solely

                           the Fund;

                  (f)      the cost of preparing and distributing reports and

                  (h)      the fees or disbursements of dividend disbursing,

                           interested persons (as defined in the 1940 Act) of
                           the Adviser without taking into consideration any of
                           their position(s) with the Fund;

                  (k)      the cost of any fidelity bond for any officer, agent
                           or employee of the Fund required under the 1940 Act
                           or otherwise; and

                  (l)      the cost of any directors and officers' insurance for
                           any directors or officers of the Fund.

                  In addition, the Fund will bear the cost of maintaining the
         effectiveness of the Fund's registration and qualification of its
         capital stock for sale (including the preparation, printing and mailing

         underwriting agreement for the Fund's shares.

                  The Fund will bear all of its extraordinary or non-recurring
         expenses, including, but not limited to, (i) any expenses of the Fund
         associated with legal claims or liabilities,


                                      -6-
<PAGE>   7

         and (ii) any expenses of the Fund associated with any litigation costs
         or indemnification related to any legal claims or liabilities.

                  The Board shall determine the manner in which expenses shall
         be allocated to the various Portfolios, and its determination shall be
         final and binding.

3.       Expense Reimbursement

                  The Adviser shall reimburse the Fund for the amount, if any,
         by which the aggregate ordinary operating expenses of any Portfolio in
         any calendar year exceed the most restrictive expense limitations then
         in effect under state securities law or regulations. No investment
         management fee payments shall be made to the Adviser with respect to
         any Portfolio during any calendar year to the extent that such payments
         would cause the expenses allocated to such Portfolio to exceed the
         expense limitation applicable to such Portfolio at the time of payment.


                                    ARTICLE V
                     LIMITATION ON LIABILITY OF THE ADVISER

         The Adviser will not be liable for any error of judgment or mistake of
law or for any loss suffered by the Fund in connection with the investment
management services it performs under this Agreement, except for a loss
resulting from willful misfeasance, bad faith, or gross negligence or reckless
disregard in the performance of the duties or obligations under this Agreement
of the Adviser (or its officers, directors, agents, employees, controlling
persons, shareholders, or any other person or entity affiliated with the Adviser
or retained by it to perform or assist in the performance of its obligations
under this Agreement). With respect to the administrative services it is
obligated to perform under this Agreement, the Adviser will not be liable for
any action taken or omitted by it in good faith without negligence.


                                   ARTICLE VI
                             NAME AND SERVICE MARKS

         The Fund may use the name "MONY Series Fund, Inc." or any name derived
from the word "MONY" and the MONY service mark only for so long as this
Agreement or any extension, renewal or amendment hereof remains in effect. At
such time as such an agreement shall no longer be in effect, the Fund will (to
the extent lawful) cease to use such a name or any other name indicating that it
is advised by or otherwise connected with the Adviser or The Mutual Life
Insurance Company of New York ("MONY"), or any organization which shall so
succeed to the business of the Adviser.

         The Adviser, on its own behalf and as agent for MONY pursuant to
express authority in the Services Agreement, hereby grants to the Fund
permission to use the word "MONY" in its


                                      -7-
<PAGE>   8

corporate name and a license to use such other service marks as have been or may
in the future be adopted by MONY, which the Adviser and the Fund determine in
goods faith to be appropriate for use by the Fund in connection with its
operations as an investment company. This license is granted on a royalty-free,
non-exclusive basis. The Adviser and MONY retain the right to use, or license
the use of, the word "MONY" and any derivative thereof, as well as such service
marks of MONY, in connection with other investment companies, subject to the
requirements of the Investment Company Act of 1940, or in connection with any
other business enterprise.

         The Fund acknowledges that the word "MONY" and the service marks of
MONY represent good will of great value to MONY and the Adviser and that MONY
and the Adviser must be able to protect and preserve such good will by
terminating the permission and license herein granted if MONY or the Adviser, in
its sole discretion, decides that it is necessary to do so or if MONY or the
Adviser decides that the Fund is no longer in a position to assure that high
quality standards will be associated with the use of the word "MONY" and the
service marks of MONY. Accordingly, if the holders of the outstanding voting
securities of the Fund or any class of voting securities of the Fund fail to
approve this Agreement and the Services Agreement, or if at any time after such
approval the Adviser or a company controlled by MONY ceases to be investment
adviser of the Fund, the Adviser (on its own or on behalf of MONY) shall have
the absolute right to terminate the license herein granted forthwith upon
written notice to the Fund. The Adviser (on its own or on behalf of MONY) shall
have the absolute right to terminate the license herein granted for any other
reason upon 60 days' written notice of such termination to the Fund, but in such
event this Agreement shall terminate on the 120th day following receipt by the
Fund of such notice unless on or prior to such day the holders of a majority of
the outstanding voting securities of each class of the Fund corresponding to a
Portfolio shall have voted in favor of the Adviser (or a company controlled by
MONY) continuing to act as investment adviser to the Fund in accordance with the
terms hereof notwithstanding the termination of the license herein granted. Upon
termination of the license herein granted, the Fund shall immediately change its
corporate name to one which does not include the word "MONY" or any derivative
hereof, and will discontinue all use by it of such word, the service marks or
anything resembling the service marks of MONY, in connection with its business.
The terms of the license herein granted shall inure to the benefit of and be
binding upon any successors or assigns of the Fund, Adviser, or MONY.


                                   ARTICLE VII
              LIMITATION ON PURCHASES OF CAPITAL STOCK OF THE FUND

         The Adviser agrees that neither it nor any of its officers or directors
will take any long or short position in the capital stock of the Fund, but this
prohibition will not prevent the purchase by or for the Adviser or any of its
officers or directors of shares of the capital stock of the Fund at the price at
which such shares are available to the public at the moment of purchase,
provided that (i) such purchase be made for investment purposes only, and (ii)
if any shares of stock so purchased are resold within two months after the date
of purchase, such fact will immediately be


                                      -8-
<PAGE>   9

reported to the Fund. In addition, this Article will not be construed to
prohibit either MONY or the Adviser from investing in the Fund in order to
provide "seed money" for the Portfolios.


                                  ARTICLE VIII
                    DURATION AND TERMINATION OF THE AGREEMENT

         This Agreement will continue in effect with respect to each Portfolio
of the Fund, whenever created until the date of the next meeting of shareholders
of the Fund following creation of the Portfolio, unless sooner terminated as
hereinafter provided. Therefore, if both this Agreement and the Services
Agreement referred to in Article I are approved by a majority vote of the
outstanding shares of capital stock of a Portfolio entitled to vote at such
meeting, this Agreement will continue in effect thereafter with respect to such
Portfolio so long as both this Agreement and said Services Agreement are
approved at least annually (i) by a majority of the non-interested directors (as
defined in the 1940 Act) of the Fund's Board of Directors, and (ii) by a
majority of the entire Board of Directors or a majority vote of the outstanding
shares of the capital stock of such Portfolio. The required shareholder approval
of this Agreement and said Services Agreement shall be effective with respect to
any Portfolio, if a majority of the outstanding shares of capital stock of such
Portfolio are voted to approve this Agreement and said Services Agreement,
notwithstanding that this Agreement or said Services Agreement (or both) may not
yet have been approved by a majority vote of the outstanding shares of the Fund.

         If, with respect to any Portfolio, the shareholders are asked to vote
on this Agreement and a majority of the outstanding shares of capital stock of
such Portfolio fail to vote to approve this Agreement or said Services Agreement
(or both), this Agreement will terminate with respect to such Portfolio. If said
Services Agreement should be so terminated, this Agreement will automatically
terminate.

         This Agreement may be terminated without payment of penalty (i) by the
Fund on at least 60 days' written notice to the Adviser, provided that such
termination be authorized by the Fund's Board of Directors or a majority vote of
the outstanding shares of capital stock of each Portfolio of the Fund as to
which the Adviser acts as investment adviser, (ii) by the fund, with respect to
any Portfolio, on at least 60 days' written notice to the Adviser, provided that
such termination be authorized by a majority vote of the outstanding shares of
the capital stock of such Portfolio, or (iii) by the Adviser on at least 90
days' written notice to the Fund.

         This Agreement will terminate automatically in the event of its
assignment (as defined in the 1940 Act) by either party.

         If this Agreement is terminated (except by virtue of assignment), in
whole or with respect to any Portfolio, and the Board of Directors of the Fund,
including a majority of the non-interested directors (as defined in the 1940
Act), so requests (and further requests that said Services Agreement similarly
continue), the Adviser will continue to act as investment adviser to the Fund or
any Portfolio thereof (as requested) for up to 120 days pending the required
approval of this Agreement or said Services Agreement (or both), approval of a
new contract with the


                                      -9-
<PAGE>   10

Adviser or a different adviser, approval of a new services contract with MONY or
a different adviser, or other definitive action. During such continuance the
compensation received by the Adviser for acting as investment adviser to the
Fund or with respect to any such Portfolio(s) will be the lesser of (i) its
actual costs incurred in furnishing investment management services or (ii) the
amount it would have received under this Agreement with respect to any such
Portfolio(s) as to which it continues to provide advice.

         This Agreement may not be amended, in whole or with respect to a
Portfolio, without the agreement thereto in writing by the Fund and the Adviser,
and approval for such amendment by (i) the Fund's Board of Directors or a
majority vote of the outstanding shares of the class of stock of such Portfolio,
and (ii) a majority of the non-interested directors (as defined in the 1940 Act)
of the Fund's Board of Directors.


                                   ARTICLE IX
                                  GOVERNING LAW

         This Agreement is subject to, and is to be interpreted in accordance
with, the provisions of the 1940 Act, and the rules and regulations of the
Securities and Exchange Commission thereunder, and the laws of the State of New
York. As used with respect to the Fund or any of its portfolios, the term
"majority of the outstanding shares" means the lesser of (i) 67 percent of the
shares represented at a meeting at which more than 50 percent of the outstanding
shares are represented or (ii) more than 50 percent of the outstanding shares.


         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
signed by their respective officers, duly authorized, as of the day and year
first above written.
