                                YIELD INFORMATION

      Set forth below is yield information for the Class A Shares of the
Domestic Money Market Fund for the seven-day period ended December 31, 1997,
computed to include and exclude realized and unrealized gains and losses and
also computed to exclude such gains and losses, and information as to the
compounded annualized yield, excluding gains and losses, for the same periods.
The yield quotations may be of limited use for comparative purposes because they
do not reflect charges imposed at the separate account level which, if included,
would decrease the yield.

Annualized Yield:
     Including gains and losses .....................    5.33%
     Excluding gains and losses......................    5.33%
Compounded Annualized Yield..........................    5.47%
Average maturity of portfolio at end of period.......    72 Days

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Domestic Money Market Fund are to
preserve shareholder capital, to maintain liquidity and to achieve the highest
possible current income consistent with the foregoing objectives by investing in
short-term domestic money market securities. There can be no assurance that the
Domestic Money Market Fund will achieve its investment objectives.

      The Domestic Money Market Fund will invest in short-term U.S. Government
securities, U.S. Government agency securities, domestic depository institution
money instruments (including certificates of deposit, bankers' acceptances, time
deposits and bank notes), short-term debt securities (such as commercial paper),
variable amount master demand notes and insurance company funding agreements,
repurchase and reverse repurchase agreements of U.S. issuers and other money
market instruments. As a matter of fundamental policy, which may be changed only
with the approval of a majority of the Domestic Money Market Fund's outstanding
voting securities, as defined in the Investment Company Act of 1940, as amended
(the "Act" or the "Investment Company Act"), the Domestic Money Market Fund may
not purchase securities of foreign issuers (including Eurodollar or Yankeedollar
bank obligations). U.S. Government securities may be purchased on a forward
commitment basis. The types of money market securities in which the Domestic
Money Market Fund may invest are described more fully in Annex A to the Appendix
to this Prospectus. The Domestic Money Market Fund will be subject to portfolio
maturity, quality and diversification restrictions discussed below.

      In addition, the Domestic Money Market Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended,
and which therefore may be subject to restrictions on their transfer or resale.
The Fund may also invest in securities the potential return of which is based on
the change in particular measurements of value or rate, (i.e. indexed
securities). A further discussion of the investments described in this paragraph
and the risks associated with such investments is set forth in the Appendix to
this Prospectus, including Annex B of the Appendix to this Prospectus, which
includes a discussion of certain portfolio strategies relating to indexed
securities.

                             PORTFOLIO RESTRICTIONS

      For purposes of the investment policy of the Domestic Money Market Fund,
the Company defines short-term money market securities as securities having a
maturity of no more than 762 days (25 months) in the case of U.S. Government and
agency securities and no more than 397 days (13 months) in the case of all other
securities. Management of the Company expects that substantially all the assets
of the Domestic Money Market Fund will be invested in securities maturing in
less than one year, but at times some portion may have maturities of up to 25
months. For these purposes, the maturity of a variable rate security is deemed
to be the next coupon date on which


                                        4
<PAGE>   7

the interest rate is adjusted. The dollar-weighted average maturity of this
Fund's portfolio assets will not exceed 90 days.

      The Domestic Money Market Fund's investments in short-term debt and
depository institution money instruments will be rated, or will be issued by
issuers who have been rated, in one of the two highest rating categories for
short-term debt obligations by a nationally recognized statistical rating
organization (an "NRSRO") or, if not rated, will be of comparable quality as
determined by the Directors of the Company. The Domestic Money Market Fund's
investments in corporate bonds and debentures (which must have maturities at the
date of purchase of 397 days (13 months) or less) will be in issuers which have
received from an NRSRO a rating, with respect to a class of short-term debt
obligations that is comparable in priority and security with the investment, in
one of the two highest rating categories for short-term obligations or, if not
rated, are of comparable quality as determined by the Directors of the Company.
Currently, there are six NRSROs: Duff & Phelps Inc., Fitch Investors Services,
Inc., IBCA Limited and its affiliate IBCA Inc., Moody's Investor's Service,
Inc., Standard & Poor's Ratings Group and Thomson BankWatch.

      A regulation of the Commission limits investments by the Domestic Money
Market Fund in securities issued by any one issuer (other than the U.S.
Government, its agencies or instrumentalities) ordinarily to not more than 5% of
its total assets, or in the event that such securities do not have the highest
rating, not more than 1% of its total assets. In addition, this regulation
requires that not more than 5% of the Fund's total assets be invested in
securities that have a rating lower than the highest rating.

      Set forth below is yield information for the Class A Shares of the Reserve
Assets Fund for the seven-day period ended December 31, 1997, computed to
include and exclude realized and unrealized gains and losses and also computed
to exclude such gains and losses, and information as to the compounded
annualized yield, excluding gains and losses, for the same periods. The yield
quotations may be of limited use for comparative purposes because they do not
reflect charges imposed at the separate account level which, if included, would
decrease the yield.

Annualized Yield:
     Including gains and losses......................    5.23%
     Excluding gains and losses......................    5.20%
Compounded Annualized Yield..........................    5.34%
Average maturity of portfolio at end of period.......    70 Days

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Reserve Assets Fund are to preserve
shareholder capital, to maintain liquidity and to achieve the highest possible
current income consistent with the foregoing objectives by investing in
short-term money market securities. There can be no assurance that the Reserve
Assets Fund will achieve its investment objectives.

      The Reserve Assets Fund will invest in short-term U.S. Government
securities, U.S. Government agency securities, depository institution money
instruments (including certificates of deposit, bankers' acceptances, time
deposits and bank notes), short-term debt securities (such as commercial paper),
variable amount master demand notes and insurance company funding agreements,
securities of foreign issuers (including Eurodollar, Yankeedollar and foreign
bank obligations) and repurchase and reverse repurchase agreements. U.S.
Government securities may be purchased on a forward commitment basis. The types
of money market securities in which the Reserve Assets Fund may invest are
described more fully in Annex A to the Appendix to this Prospectus. The Reserve
Assets Fund will be subject to the portfolio maturity, quality and
diversification restrictions discussed below.

      In addition, the Reserve Assets Fund may purchase certain securities that
are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The
Reserve Assets Fund may also invest in securities of foreign issuers and in
securities the potential return of which is based on the change in particular
measurements of value or rate (i.e. indexed securities). A further discussion of
the investments described in this paragraph and the risks associated with such
investments is set forth in the Appendix to this Prospectus, including Annex B
of the Appendix to this Prospectus, which includes a discussion of certain
portfolio strategies relating to indexed securities.

                             PORTFOLIO RESTRICTIONS

      For purposes of the investment policy of the Reserve Assets Fund, the
Company defines short-term money market securities as securities having a
maturity of no more than 762 days (25 months) in the case of U.S. Government and
agency securities and no more than 397 days (13 months) in the case of all other
securities. Management of the Company expects that substantially all the assets
of the Reserve Assets Fund will be invested in securities maturing in less than
one year, but at times some portion may have maturities of up to 25 months. For
these purposes, the maturity of a variable rate security is deemed to be the
next coupon date on which the interest rate is adjusted. The dollar-weighted
average maturity of this Fund's portfolio assets will not exceed 90 days.

      The Reserve Asset Fund's investments in short-term debt and depository
institution money instruments will be rated, or will be issued by issuers who
have been rated, in one of the two highest rating categories for short-term debt
obligations by a nationally recognized statistical rating organization (an
"NRSRO") or, if not rated, will


                                        4
<PAGE>   12

be of comparable quality as determined by the Directors of the Company. The
Reserve Assets Fund's investments in corporate bonds and debentures (which must
have maturities at the date of purchase of 397 days (13 months) or less) will be
in issuers which have received from an NRSRO a rating, with respect to a class
of short-term debt obligations that is comparable in priority and security with
the investment, in one of the two highest rating categories for short-term
obligations or, if not rated, are of comparable quality as determined by the
Directors of the Company. Currently, there are six NRSROs: Duff & Phelps Inc.,
Fitch Investors Services, Inc., IBCA Limited and its affiliate IBCA Inc.,
Moody's Investors Service, Inc., Standard & Poor's Ratings Group and Thomson
BankWatch.

      A regulation of the Commission limits investments by the Reserve Assets
Fund in securities issued by any one issuer (other than the U.S. Government, its
agencies or instrumentalities) ordinarily to not more than 5% of its total
assets, or in the event that such securities do not have the highest rating, not
more than 1% of its total assets. In addition, this regulation requires that not
more than 5% of the Reserve Assets Fund's total assets be invested in securities
that have a rating lower than the highest rating.

                       INVESTMENT OBJECTIVES AND POLICIES

      The principal investment objective of the Prime Bond Fund is to provide
shareholders with as high a level of current income as is consistent with the
investment policies of the Fund and with prudent investment management. As a
secondary objective, the Prime Bond Fund seeks capital appreciation when
consistent with its principal objective. There can be no assurance that the
Prime Bond Fund will achieve its investment objectives.

      The Prime Bond Fund invests primarily in securities rated in the top three
rating categories of either Standard & Poor's (AAA, AA and A) or Moody's (Aaa,
Aa and A). Additional information regarding various bond ratings is set forth in
Annex A to the Appendix to this Prospectus. The financial risk of this Fund
should be minimized by the credit quality of the bonds in which it will invest,
but the long maturities that typically provide the best yield will subject the
Fund to possible substantial price changes resulting from market yield
fluctuations. The market prices of fixed-income securities such as those
purchased by the Prime Bond Fund are affected by changes in interest rates
generally. As interest rates rise, the market value of fixed-income securities
will fall, adversely affecting the net asset value of the Fund. The Fund should
be considered a long-term investment and a vehicle for diversification, and not
as a balanced investment program. The Fund may not be appropriate as the
exclusive investment to fund a variable annuity or variable life insurance
contract ("Contract") for all Contract owners.

      Fund management strategy will attempt to mitigate adverse price changes
and optimize favorable price changes through active trading that shifts the
maturity and/or quality structure of the Fund within the overall investment
guidelines. The Prime Bond Fund's investments will vary from time to time
depending upon the judgment of management as to prevailing conditions in the
economy and the securities markets and the prospects for interest rate changes
among different categories of fixed-income securities. The Prime Bond Fund
anticipates that under normal circumstances more than 90% of the assets of the
Fund will be invested in fixed-income securities, including convertible and
non-convertible debt securities and preferred stock. The Prime Bond Fund does
not intend to invest in common stock, rights or other equity securities. Under
unusual market or economic conditions, the Prime Bond Fund for defensive or
other purposes may invest up to 100% of its assets in U.S. Government or
Government agency securities, money market or other fixed-income securities
deemed by the Investment Adviser to be consistent with the objectives of the
Fund, or the Fund may hold its assets in cash.

      In addition, the Prime Bond Fund may purchase certain securities that are
not registered under the Securities Act of 1933, as amended, and which therefore
may be subject to restrictions on their transfer or resale. The Fund may also
invest in securities of foreign issuers and may invest in securities the
potential return of which is based on the change in particular measurements of
value or rate (i.e., indexed securities). A further discussion of the
investments described in this paragraph and the risks associated with such
investments is set forth in the Appendix to this Prospectus, including Annex B
of the Appendix to this Prospectus, which includes a discussion of certain
portfolio strategies relating to indexed securities.

                       INVESTMENT OBJECTIVES AND POLICIES

      The primary investment objective of the High Current Income Fund is to
obtain the highest level of current income that is consistent with the
investment policies of the Fund and with prudent investment management. As a
secondary objective, the High Current Income Fund seeks capital appreciation
when consistent with its primary objective. There can be no assurance that the
High Current Income Fund will achieve its investment objectives.

      The High Current Income Fund seeks high current income by investing
principally in fixed-income securities that are rated in the lower rating
categories of the established rating services (Baa or lower by Moody's Investors
Service Inc. ("Moody's") and BBB or lower by Standard & Poor's Ratings Group
("Standard & Poor's"), or in unrated securities of comparable quality.
Securities rated below Baa by Moody's and below BBB by Standard & Poor's are
commonly known as "junk bonds." Additional information regarding various bond
ratings is set forth in Annex A to the Appendix to this Prospectus. The market
price of fixed-income securities such as those purchased by the Fund is affected
by changes in interest rates generally. As interest rates rise, the market value
of fixed-income securities will fall, adversely affecting the net asset value of
the Fund.

      Although they can be expected to provide higher yields, lower-rated
securities such as those purchased by the High Current Income Fund may be
subject to greater market fluctuations and risks of loss of income and principal
than lower-yielding, higher-rated fixed-income securities. Such securities are
generally issued by corporations that are not as financially secure or as
creditworthy as issuers of higher-rated securities. There is, accordingly, a
greater risk that the issuers of higher-yielding securities will not be able to
pay principal and interest on such securities, especially during periods of
adverse economic conditions. Investment in such high-yield securities entails
relatively greater risk of loss of income or principal. The Fund should be
considered a long-term investment and a vehicle for diversification, and not as
a balanced investment program. The Fund may not be appropriate as the exclusive
investment to fund a variable annuity or variable life insurance contract
("Contract") for all Contract owners. See "Investment Objectives and Policies of
the Funds -- Risks of High Yield Securities" in the Appendix to this Prospectus.

      Selection and supervision by the management of the Company regarding
investments in lower-rated fixed-income securities involves continuous analysis
of individual issuers, general business conditions and other factors that may be
too time consuming or too costly for the average investor. The furnishing of
these services does not, of course, guarantee successful results. The analysis
of issuers may include, among other things, historic and current financial
condition, current and anticipated cash flow and borrowing requirements, value
of assets in relation to historical cost, strength of management, responsiveness
to business conditions, credit standing, and current and anticipated results of
operations. Analysis of general business conditions and other factors may
include anticipated changes in economic activity and interest rates, the
availability of new investment opportunities, and the economic outlook for
specific industries. While Merrill Lynch Asset Management, L.P. (the "Investment
Adviser") considers as one factor in its credit analysis the ratings assigned by
the rating services, the Investment Adviser performs its own independent credit
analysis of issuers and consequently, the High Current Income Fund may invest,
without limit, in unrated securities if such securities offer, in the opinion of
the Investment Adviser, a relatively high yield without undue risk. As a result,
the High Current Income Fund's ability to achieve its investment objective may
depend to a greater extent on the Investment Adviser's own credit analysis than
the Funds which invest in higher- rated securities. Although the High Current
Income Fund will invest primarily in lower-rated securities, it will not invest
in securities rated Ca or lower by Moody's and CC or lower by Standard & Poor's
unless the Investment Adviser believes that the financial condition of the
issuer or the protection afforded to the particular securities is stronger than
would otherwise be indicated by such low ratings. However, securities purchased
by the High Current Income Fund may subsequently be downgraded. Such securities
may continue to be held and will be sold only if, in the judgment of the
Investment Adviser, it is advantageous to do so.

      When changing economic conditions and other factors cause the yield
difference between lower-rated and higher-rated securities to narrow, the High
Current Income Fund may purchase higher-rated securities if the Investment
Adviser believes that the risk of loss of income and principal may be
substantially reduced with only a relatively small reduction in yield.


                                        4
<PAGE>   21

      The securities in the High Current Income Fund will be varied from time to
time depending upon the judgment of management as to prevailing conditions in
the economy and the securities markets and the prospects for interest rate
changes among different categories of fixed-income securities. It is anticipated
that under normal circumstances more than 90% of the High Current Income Fund's
assets will be invested in fixed-income securities, including convertible and
non-convertible debt securities and preferred stock. Although it is expected
that, in general, the Fund will not invest in common stocks, rights or other
equity securities, it will acquire or hold such securities (if consistent with
the objectives of the Fund) when such securities are acquired in unit offerings
with fixed-income securities or in connection with an actual or proposed
conversion or exchange of fixed-income securities. In addition, under unusual
market or economic conditions, the High Current Income Fund for defensive
purposes may invest up to 100% of its assets in U.S. Government or Government
agency securities, money market securities or other fixed-income securities
deemed by the Investment Adviser to be consistent with a defensive posture, or
may hold its assets in cash. The yield on such securities may be lower than the
yield on lower-rated fixed-income securities.

      The table below shows the average monthly dollar-weighted market value, by
Standard & Poor's rating category, of the securities held by the High Current
Income Fund during the fiscal year ended December 31, 1997.

                        INVESTMENT OBJECTIVE AND POLICIES

      The Quality Equity Fund seeks to achieve the highest total investment
return, or the aggregate of income and capital value changes, consistent with
prudent risk. To do this, management will shift the emphasis among investment
alternatives for capital growth, capital stability and income as market trends
change. This "fully managed" investment policy distinguishes the Quality Equity
Fund from investment companies which seek either capital growth or income. The
Quality Equity Fund's investment philosophy is based on management's belief that
the structure of the United States economy and its securities markets will
undergo continuous change. The flexibility of the Fund is designed to reduce
overall exposure to risk by achieving below-average volatility in a falling
market and above-average volatility in a rising market. There can be no
assurance that the Quality Equity Fund will achieve its investment objective.
The Fund may employ a variety of investments and techniques to hedge against
market and currency risk. See Annex B to the Appendix of this Prospectus.

      The Quality Equity Fund's fully managed investment approach will make use
of equity, debt and convertible securities. The majority of the Fund's equity
portfolio will be in the common stocks of large- capitalization, "quality"
companies. For this purpose, "large capitalization" companies are considered to
be those companies with market capitalizations in excess of $500 million.
Management of the Company believes that a quality company is one which conforms
closely to the following criteria: good financial resources, strong balance
sheet, satisfactory rate of return on capital, good industry position and
superior management skills. The earnings of quality companies generally tend to
grow consistently. Whenever market or financial conditions warrant, the Quality
Equity Fund may, in order to reduce risk and achieve the highest total
investment return, invest in non-convertible, long-term debt securities,
including "deep discount" corporate debt securities of investment grade or
issues of fixed-income convertible securities which give the owner the option of
a later exchange for common stock. Management expects that over longer periods
the larger portion of the Quality Equity Fund's portfolio will consist of equity
securities. The Fund should be considered a long-term investment and a vehicle
for diversification, and not as a balanced investment program. The Fund may not
be appropriate as the exclusive investment to fund a variable annuity or
variable life insurance contract ("Contract") for all Contract owners. During
defensive periods, the Fund may invest in U.S. Government and Government agency
securities, money market securities or other fixed-income securities deemed by
the Merrill Lynch Asset Management L.P. (the "Investment Adviser") to be
consistent with a defensive posture, or cash.

Other Investments and Risks

      In addition, the Quality Equity Fund may purchase certain securities that
are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The Fund
may also invest in securities of foreign issuers, may from time to time be
invested in non-dollar- denominated securities of foreign issuers, and is
authorized to write (i.e., sell) call options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio. Changes in foreign currency
exchange rates may affect the value of securities in the portfolio and the
unrealized appreciation or depreciation of investments insofar as United States
investors are concerned. Furthermore, the Quality Equity Fund's return on
investments in non-dollar-denominated securities may be reduced or enhanced as a
result of changes in foreign currency rates during the period in which the Fund
holds such investments.

      The Quality Equity Fund may engage in transactions, such as currency swaps
and purchasing and selling options on currencies, for purposes of hedging
against the decline in the value of currencies in which its portfolio holdings
are denominated against the US dollar. Although such instruments will be used
with the intention of hedging against adverse currency movements, transactions
in such instruments involve the risk that anticipated currency movements will
not be accurately predicted and that the Fund's hedging strategies will be
ineffective and may cause the Fund to realize losses.

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to options and foreign exchange
transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Special Value Focus Fund is to seek
long-term growth of capital by investing in a diversified portfolio of
securities, primarily common stocks, of relatively small companies that
management of the Company believes have special investment value, and of
emerging growth companies regardless of size. There can be no assurance that the
Special Value Focus Fund will achieve its investment objective. Companies are
selected by management on the basis of their long-term potential for expanding
their size and profitability or for gaining increased market recognition for
their securities. Current income is not a factor in the selection of securities.
The Special Value Focus Fund is intended to provide an opportunity for owners
("Contract Owners") of variable annuity contracts and/or variable life insurance
contracts ("Contracts") who are not ordinarily in a position to perform the
specialized type of research or analysis of small and emerging growth companies.

      Management seeks to identify those small emerging growth companies that
can show significant and sustained increases in earnings over an extended period
of time and are in sound financial condition. Management believes that, while
these companies present above-average risks, properly selected companies of this
type also have the potential to increase their earnings at a rate substantially
in excess of the general growth of the economy. The Special Value Focus Fund
attempts to achieve its objective by focusing on the long-range view of a
company's prospects through a fundamental analysis of its management, financial
structure, product development, marketing ability and other relevant factors.
Full development of these companies frequently takes time and, for this reason,
the Special Value Focus Fund should not be considered as a vehicle for seeking
short-term profits. The Fund should be considered a long-term investment and a
vehicle for diversification, and not as a balanced investment program.

      Small companies. Management seeks small companies that offer special
investment value in terms of their product or service, research capability, or
other unique attributes, and are relatively undervalued in the marketplace when
compared with similar, but larger, enterprises. These companies typically have
total market capitalizations in the $50-$300 million range and generally are
little known to most individual investors, although some may be dominant in
their respective industries. Underlying this strategy is management's belief
that relatively small companies will continue to have the opportunity to develop
into significant business enterprises. Some such companies may be in a
relatively early stage of development; others may manufacture a new product or
perform a new service. Such companies may not be counted upon to develop into
major industrial companies, but management believes that eventual recognition of
their special value characteristics by the investment community can provide
above-average long-term growth to the portfolio.

      Emerging growth companies. In selecting investments for the Special Value
Focus Fund, management also seeks emerging growth companies that either occupy a
dominant position in an emerging industry or subindustry or have a significant
and growing market share in a large, fragmented industry. Management believes
that capable and flexible management is one of the most important criteria of
emerging growth companies and that such companies should employ sound financial
and accounting policies and also demonstrate effective research, successful
product development and marketing, efficient service and pricing flexibility.
Emphasis is given to companies with rapid historical growth rates, above-average
returns on equity and strong current balance sheets, all of which should enable
the company to finance its continued growth. Management of the Company also
analyzes and weighs relevant factors beyond the company itself, such as the
level of competition in the industry, the extent of governmental regulation, the
nature of labor conditions and other related matters.

      The Special Value Focus Fund emphasizes investments in companies that do
most of their business in the United States and therefore are free of the
currency exchange problems, foreign tax considerations and potential political
and economic upheavals that many multinational corporations face. Moreover, the
size and kinds of markets that they serve make these companies less susceptible
than larger companies to intervention from the federal government by means of
price controls, regulations or litigation.

      While the process of selection and continuous supervision by management
does not, of course, guarantee successful investment results, it does provide
ingredients not available to the average individual due to the time and cost
involved. Careful initial selection is particularly important in this area as
many new enterprises have promise but lack certain of the ingredients necessary
to prosper.

      It should be apparent that an investment in a fund such as the Special
Value Focus Fund involves greater risk than is customarily associated with more
established companies. The securities of smaller or emerging growth companies
may be subject to more abrupt or erratic market movements than larger, more
established companies or the market average in general. These companies may have
limited product lines, markets or financial resources, or they may be dependent
upon a limited management group. Because of these factors, management of the
Company believes that shares in the Special Value Focus Fund are suitable for
Contract Owners who are in a financial position to assume above-average
investment risk in search of above-average long-term reward. As indicated, the
Special Value Focus Fund is designed for Contract Owners whose investment
objective is growth rather than income. It is definitely not intended for
exclusive funding of Contracts but is designed for Contract Owners who are
prepared to experience above-average fluctuations in net asset value.

      The securities in which the Special Value Focus Fund invests will often be
traded only in the over-the-counter market or on a regional securities exchange
and may not be traded every day or in the volume typical of trading on a
national securities exchange. As a result, the disposition by the Fund of
portfolio securities to meet redemptions or otherwise may require the Fund to
sell these securities at a discount from market prices or during periods when in
management's judgment such disposition is not desirable or to make many small
sales over a lengthy period of time.

      The investment emphasis of the Special Value Focus Fund is on equities,
primarily common stock and, to a lesser extent, securities convertible into
common stocks and rights to subscribe for common stock, and the Fund will
maintain at least 80% of its net assets invested in equity securities of small
or emerging growth companies except during defensive periods. The Special Value
Focus Fund reserves the right as a defensive measure and to provide for
redemptions to hold other types of securities, including non-convertible
preferred stocks and debt securities, U.S. Government and Government agency
securities, money market securities or other fixed-income securities deemed by
the Investment Adviser to be consistent with a defensive posture, or cash, in
such proportions as, in the opinion of management, prevailing market or economic
conditions warrant.

      In addition, the Special Value Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The Fund
may also invest in securities of foreign issuers and is authorized to write
(i.e., sell) call options on securities held in its portfolio or securities
indices the performance of which is substantially correlated with securities
held in its portfolio. A further discussion of the investments described in this
paragraph and the risks associated with such investments is set forth in the
Appendix to this Prospectus, including Annex B of the Appendix to this
Prospectus, which includes a discussion of certain portfolio strategies relating
to options.

## For fiscal years beginning on or after September 1, 1995, the Fund is
   required to disclose its average commission rate per share for purchases and
   sales of equity securities. The "Average Commission Rate Paid" includes
   commissions paid in foreign currencies, which have been converted into U.S.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Natural Resources Focus Fund are to
achieve long-term growth of capital and to protect the purchasing power of
shareholders' capital by investing primarily in a portfolio of equity securities
(e.g., common stocks and securities convertible into common stocks) of domestic
and foreign companies with substantial natural resource assets. This investment
objective is a fundamental policy and may not be changed without a vote of the
majority of outstanding shares of the Natural Resources Focus Fund. The Natural
Resources Focus Fund also may invest in debt, preferred or convertible
securities, the value of which is related to the market value of some natural
resource asset ("asset-based securities"). Management of the Company will seek
to identify companies or asset-based securities it believes are attractively
priced relative to the intrinsic value of the underlying natural resource assets
or are especially well positioned to benefit during particular portions of
inflationary cycles. The Fund should be considered a long-term investment and a
vehicle for diversification, and not as a balanced investment program. The Fund
may not be appropriate as the exclusive investment to fund a variable annuity or
variable life insurance contract ("Contract") for all Contract owners. There can
be no assurance that the Natural Resources Focus Fund will achieve its
investment objectives.

      IN SEEKING TO PROTECT THE PURCHASING POWER OF SHAREHOLDERS' CAPITAL, THE
NATURAL RESOURCES FOCUS FUND HAS RESERVED THE RIGHT, WHEN MANAGEMENT OF THE
COMPANY ANTICIPATES SIGNIFICANT ECONOMIC, POLITICAL OR FINANCIAL INSTABILITY,
SUCH AS HIGH INFLATIONARY PRESSURES OR UPHEAVAL IN THE FOREIGN CURRENCY EXCHANGE
MARKETS, TO INVEST A MAJORITY OF ITS ASSETS IN COMPANIES THAT EXPLORE FOR,
EXTRACT, PROCESS OR DEAL IN GOLD OR IN ASSET-BASED SECURITIES INDEXED TO THE
VALUE OF GOLD BULLION. Such a switch in investment strategies could require the
Fund to liquidate portfolio securities and incur transaction costs. The Company
has been advised by counsel that it is uncertain under the current federal tax
law whether the Fund may concentrate its investments in gold and gold-related
securities without adversely affecting the federal tax status of the Contracts.
Accordingly, management of the Company has determined that the Natural Resources
Focus Fund will not concentrate its investments in such securities until counsel
has advised the Company that such uncertainty has been resolved favorably.

      Management attempts to achieve the investment objectives of the Natural
Resources Focus Fund by seeking to identify securities of companies which, in
its opinion, are undervalued relative to the value of natural resource holdings
of such companies in light of current and anticipated economic or financial
conditions. Natural resource assets are materials derived from natural sources
which have economic value. Management will consider a company to have
substantial natural resource assets when, in its opinion, the company's holdings
of the assets are of such magnitude, when compared to the capitalization,
revenues or operating profits of the company, that changes in the economic value
of the assets are expected to affect the market price of the equity securities
of such company. Generally, a company has substantial natural resource assets
when at least 50% of the non-current assets, capitalization, gross revenues or
operating profits of the company in the most recent or current fiscal year are
involved in or result from directly or indirectly through subsidiaries,
exploring, mining, refining, processing, fabricating, dealing in or owning
natural resource assets. Examples of natural resource assets include precious
metals (e.g., gold, silver and platinum), ferrous and nonferrous metals (e.g.,
iron, steel, aluminum and copper), strategic metals (e.g., uranium and
titanium), hydrocarbons (e.g., coal, oil and natural gas), timber land,
undeveloped real property and agricultural commodities. The Fund presently does
not intend to invest directly in natural resource assets or contracts related
thereto.

      Management of the Company believes that, based upon past performance, the
securities of specific companies that hold different types of substantial
natural resource assets may move relatively independently of one another during
different stages of inflationary cycles due to different degrees of demand for,
or market values of, their respective natural resource holdings during
particular portions of such inflationary cycles. The Fund's fully managed
investment approach enables it to switch its emphasis among various industry
groups depending upon management's outlook with respect to prevailing trends and
developments.

      The Natural Resources Focus Fund at all times, except during defensive
periods, will maintain at least 65% of its total assets invested in companies
with substantial natural resource assets or in asset-based securities. Current


                                        4
<PAGE>   35

income from dividends and interest will not be a primary consideration in
selecting securities. The Fund reserves the right as a temporary defensive
measure and to provide for redemptions, to hold short-term U.S. Government and
Government agency securities, money market securities or other fixed-income
securities deemed by the Investment Adviser to be consistent with a defensive
posture, or cash, in such proportions as, in the opinion of management,
prevailing market or economic conditions warrant.

      As indicated above, under certain circumstances, the Natural Resources
Focus Fund has reserved the right to invest a majority of its assets in
gold-related companies or securities. Based on historic experience, during
periods of economic or financial instability, the securities of such companies
may be subject to extreme price fluctuations, reflecting the high volatility of
gold prices during such periods. In addition, the instability of gold prices may
result in volatile earnings of gold-related companies which, in turn, may affect
adversely the financial condition of such companies. Gold mining companies also
are subject to the risks generally associated with mining operations.

      The major producers of gold include the Republic of South Africa, Russia,
the United States, Australia, Canada, the People's Republic of China and the
Philippines. Sales of gold by Russia and the People's Republic of China are
largely unpredictable and often relate to political and economic considerations
rather than to market forces. Economic, social and political developments within
Russia, the People's Republic of China and the Republic of South Africa may
affect significantly gold production in those countries.

Other Investments and Risks

      In addition, the Natural Resources Focus Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended,
and which therefore may be subject to restrictions on their transfer or resale.
The Fund may also engage in transactions for purpose of hedging against the
decline in the value of currencies in which its portfolio holdings are
denominated against the US dollar. The Fund is also authorized to write (i.e.,
sell) and purchase call and put options on securities held in its portfolio, on
securities indices the performance of which is substantially correlated with
securities held in its portfolio or on securities it intends to purchase, may
engage in transactions in futures, and may invest in securities the potential
return of which is based on the change in particular measurements of value or
rate (i.e., indexed and inverse securities).

      The Natural Resources Focus Fund may also invest in securities of foreign
issuers and may concentrate its investments in one or more countries.
Investments in foreign securities, particularly those of non-governmental
issuers, involve considerations and risks which are not ordinarily associated
with investing in domestic issuers. These considerations and risks include
changes in currency rates, currency exchange control regulations, the
possibility of expropriation, confiscatory taxation, high rates of inflation,
the unavailability of financial information or the difficulty of interpreting
financial information prepared under foreign accounting standards, less
liquidity and more volatility in foreign securities markets, the impact of
political, social or diplomatic developments, and the difficulty of assessing
economic trends in foreign countries. In addition, net investment income earned
by the Fund on a foreign security may be subject to withholding and other taxes
imposed by foreign governments which will reduce the Fund's net investment
income. The Natural Resources Focus Fund may also from time to time be
substantially invested in non-dollar-denominated securities of foreign issuers.
Changes in foreign currency exchange rates may affect the value of securities in
the portfolio and the unrealized appreciation or depreciation of investments
insofar as United States investors are concerned. Furthermore, the Fund's return
on investments in non- dollar-denominated securities may be reduced or enhanced
as a result of changes in foreign currency rates during the period in which the
Fund holds such investments. See "Other Portfolio Strategies -- Foreign
Securities" in the Appendix to this Prospectus for special considerations
concerning investments in foreign securities.

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed and inverse securities,
options, futures and foreign exchange transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the American Balanced Fund is to seek a level
of current income and a degree of stability of principal not normally available
from an investment solely in equity securities and the opportunity for capital
appreciation greater than is normally available from an investment solely in
debt securities by investing in a balanced portfolio of fixed income and equity
securities. This investment objective is a fundamental policy and may not be
changed without a vote of the majority of the outstanding shares of the American
Balanced Fund. The American Balanced Fund will seek current income by investing
a portion of its assets in a portfolio of intermediate to long-term debt,
convertible debt, non-convertible and convertible term preferred stock and money
market securities. The American Balanced Fund will seek capital appreciation
primarily by investing a portion of its assets in equity securities, including
perpetual preferred and convertible perpetual preferred stock. At all times the
Fund will maintain at least 25% of its net assets in senior fixed income
securities. As a non-fundamental policy, the Fund is not permitted to invest in
securities of foreign issuers. There can be no assurance that the American
Balanced Fund will achieve its investment objective.

      The Fund will normally limit its allocation of assets to equity securities
to no more than 65% of its net assets. To the extent its equity position exceeds
this limitation, because of changes in the value of portfolio securities or
otherwise, the Fund will seek to reduce its equity position to less than 65% of
net assets by selling such securities at such times and in such amounts as
management of the Company deems appropriate in light of market conditions and
other pertinent factors. See "Dividends, Distributions and Taxes -- Tax
Treatment of the Company" in the Appendix to this Prospectus.

      The American Balanced Fund will generally emphasize investment in common
stocks of larger-capitalization issuers and in investment-grade debt
obligations. The Fund may also seek to enhance the return on its common stock
portfolio by writing covered call options listed on United States securities
exchanges. Under unusual market or economic conditions, the Fund for defensive
purposes may invest up to 100% of its assets in short-term U.S. Government or
Government agency securities, money market securities or other fixed-income
securities deemed by the Investment Adviser to be consistent with a defensive
posture, or cash.

      In addition, the American Balanced Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The Fund
is authorized to write (i.e., sell) call options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio. A further discussion of the
investments described in this paragraph and the risks associated with such
investments is set forth in the Appendix to this Prospectus, including Annex B
of the Appendix to this Prospectus, which includes a discussion of certain
portfolio strategies relating to options.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Strategy Focus Fund is to seek high
total investment return by investing primarily in a portfolio of equity and
fixed income securities, including convertible securities, of U.S. and foreign
issuers. Total investment return consists of interest, dividends, discount
accruals and capital changes, including changes in the value of non-dollar
denominated securities and other assets and liabilities resulting from currency
fluctuations. There can be no assurance that the Global Strategy Focus Fund will
achieve its investment objective. Investing on an international basis involves
special considerations. See "Other Investments and Risks" below.

      The Global Strategy Focus Fund seeks to achieve its objective by investing
primarily in the securities of issuers located in the United States, Canada,
Western Europe, the Far East and Latin America. There are no prescribed limits
on the geographical allocation of the Fund among these regions. Such allocation
will be made primarily on the basis of the anticipated total return from
investments in the securities of issuers wherever located, considering such
factors as the condition and growth potential of the various economies and
securities markets and the issuers domiciled therein, anticipated movements in
interest rates in the various capital markets and in the value of foreign
currencies relative to the U.S. dollar, tax considerations and economic, social,
financial, national and political factors which may affect the climate for
investing within such securities markets. When, in the judgment of Merrill Lynch
Asset Management L.P. (the "Investment Adviser"), economic or market conditions
warrant, the Fund reserves the right to concentrate its investments in one or
more capital markets, including the United States. The Fund should be considered
a long-term investment and a vehicle for diversification, and not as a balanced
investment program. The Fund may not be appropriate as the exclusive investment
to fund a variable annuity or variable life insurance contract ("Contract") for
all owners.

      The corporate debt securities, including convertible debt securities, in
which the Fund may invest will be rated BBB or better by Standard and Poor's
Ratings Group ("Standard & Poor's") or Baa or better by Moody's Investors
Service, Inc. ("Moody's") or, in the opinion of the Investment Adviser, of
comparable quality. The Fund may also invest in debt obligations issued or
guaranteed by sovereign governments, political subdivisions thereof (including
states, provinces and municipalities) or their agencies or instrumentalities or
issued or guaranteed by international organizations designated or supported by
governmental entities to promote economic reconstruction or development
("supranational entities") such as the International Bank for Reconstruction and
Development (the "World Bank") and the European Coal and Steel Community.
Investments in securities of supranational entities are subject to the risk that
member governments will fail to make required capital contributions and that a
supranational entity will thus be unable to meet its obligations.

      When market or financial conditions warrant, the Global Strategy Focus
Fund may invest as a temporary defensive measure up to 100% of its assets in
U.S. Government or Government agency securities, money market securities or
other fixed income securities deemed by the Investment Adviser to be consistent
with a defensive posture, or may hold its assets in cash.

      The Global Strategy Focus Fund may use derivatives in connection with
certain trading strategies. See Annex B of the Appendix to this Prospectus.

Other Investments and Risks

      In addition, the Global Strategy Focus Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended,
and which therefore may be subject to restrictions on their transfer or resale.
The Global Strategy Focus Fund may also invest in securities of foreign issuers
and may concentrate its investments in one or more countries. Investments in
foreign securities, particularly those of non-governmental issuers, involve
considerations and risks that are not ordinarily associated with investing in
domestic issuers. These considerations and risks include changes in currency
rates, currency exchange control regulations, the possibility of expropriation,
confiscatory taxation, high rates of inflation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of political, social or diplomatic
developments, and the difficulty of assessing economic trends in foreign
countries. In addition, net investment income earned by the Fund on a


                                        4
<PAGE>   44

foreign security may be subject to withholding and other taxes imposed by
foreign governments, which will reduce the Fund's net investment income. The
Fund may also from time to time be substantially invested in non-dollar-
denominated securities of foreign issuers. Changes in foreign currency exchange
rates may affect the value of securities in the portfolio and the unrealized
appreciation or depreciation of investments insofar as United States investors
are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. For additional information concerning the risks of investing in
foreign securities, see "Other Portfolio Strategies -- Foreign Securities" in
the Appendix to this Prospectus.

      The Global Strategy Focus Fund may engage in transactions, such as
currency swaps and purchasing and selling options on currencies, for purposes of
hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. The Fund is also authorized to
purchase and to write (i.e., sell) call and put options on securities held in
its portfolio, securities indices the performance of which is substantially
correlated with securities held in its portfolio or on securities it intends to
purchase and to purchase put options on securities held in its portfolio and may
also invest in futures and in securities the potential return of which is based
on the change in particular measurements of value of rate (i.e. indexed and
inverse securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed and inverse securities,
options, futures and foreign exchange transactions.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Basic Value Focus Fund are to seek
capital appreciation and, secondarily, income by investing in securities,
primarily equities, that management of the Fund believes are undervalued and
therefore represent basic investment value. There can be no assurance that the
Basic Value Focus Fund will achieve its investment objectives. The Fund seeks
special opportunities in securities that are selling at a discount, either from
book value or historical price-earnings ratios, or seem capable of recovering
from temporarily out of favor considerations. Particular emphasis is placed on
securities that provide an above-average dividend return and sell at a
below-average price-earnings ratio. The Fund should be considered a long-term
investment and a vehicle for diversification, and not as a balanced investment
program. The Fund may not be appropriate as the exclusive investment to fund a
variable annuity or variable life insurance contract ("Contract") for all
Contract owners.

      The investment policy of the Basic Value Focus Fund is based on the belief
that the pricing mechanism of the securities market lacks total efficiency and
has a tendency to inflate prices of securities in favorable market climates and
depress prices of securities in unfavorable climates. Based on this premise,
management believes that favorable changes in market prices are more likely to
begin when securities are out of favor, earnings are depressed, price-earnings
ratios are relatively low, investment expectations are limited, and there is no
real general interest in the particular security or industry involved. On the
other hand, management believes that negative developments are more likely to
occur when investment expectations are generally high, stock prices are
advancing or have advanced rapidly, price-earnings ratios have been inflated,
and the industry or issue continues to gain new investment acceptance on an
accelerated basis. In other words, management believes that market prices of
securities with relatively high price-earnings ratios are more susceptible to
unexpected adverse developments while securities with relatively low
price-earnings ratios are more favorably positioned to benefit from favorable,
but generally unanticipated, events. This investment policy departs from
traditional philosophy. Management of the Fund believes that the market risk
involved in this policy is moderated somewhat by an emphasis on securities with
above-average dividend returns.

      The current institutionally-dominated market tends to ignore, to some
extent, the numerous secondary issues whose market capitalizations are below
those of the relatively few larger size growth companies. It is expected that
the Basic Value Focus Fund's portfolio generally will have significant
representation in this secondary segment of the market. The basic orientation of
the Fund's investment policies is such that at times a large portion of its
common stock holdings may carry less than favorable research ratings from
research analysts.

      Investment emphasis is on equities, primarily common stock and, to a
lesser extent, securities convertible into common stocks. The Basic Value Focus
Fund also may invest in preferred stocks and non-convertible debt securities
rated investment grade and utilize covered call options with respect to
portfolio securities as described in Annex B to the Appendix of this Prospectus.
The Fund reserves the right as a defensive measure to hold other types of
securities, including U.S. Government and Government agency securities, money
market securities or other fixed-income securities deemed by the Investment
Adviser to be consistent with a defensive posture, or cash, in such proportions
as, in the opinion of management, prevailing market or economic conditions
warrant. The Fund may invest up to 10% of its total assets, taken at market
value at the time of acquisition, in the securities of foreign issuers.

      In addition, the Basic Value Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The Fund
is also authorized to write (i.e., sell) call options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio. A further discussion of the
investments described in this paragraph and the risks associated with such
investments is set forth in the Appendix to this Prospectus, including Annex B
of the Appendix to this Prospectus, which includes a discussion of certain
portfolio strategies relating to options.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Bond Focus Fund is to seek to
provide shareholders a high total investment return by investing in a global
portfolio of fixed income securities denominated in various currencies,
including multi-national currency units. The Fund will, under normal conditions,
invest at least 90% of its total assets in such fixed income securities. In
pursuing its investment objective, the Global Bond Focus Fund will allocate its
investments among different types of fixed income securities denominated in
various currencies based upon Merrill Lynch Asset Management L.P.'s (the
"Investment Adviser") analysis of the yield, maturity, potential appreciation
and currency considerations affecting such securities. There can be no assurance
that the Global Bond Focus Fund will achieve its investment objective. Investing
on an international basis involves special considerations. See "Other
Investments and Risks" below. The Fund should be considered a long-term
investment and a vehicle for diversification, and not as a balanced investment
program. The Fund may not be appropriate as the exclusive investment to fund a
variable annuity or variable life insurance contract ("Contract") for all
Contract owners.

      The Global Bond Focus Fund may invest in United States and foreign
government and corporate fixed income securities that have a credit rating of A
or better by Standard & Poor's Rating Group ("Standard & Poor's") or by Moody's
Investors Service, Inc. ("Moody's") or commercial paper rated A-1 by Standard &
Poor's or Prime- 1 by Moody's or obligations that the Investment Adviser has
determined to be of similar creditworthiness. The Fund may purchase fixed income
securities issued by United States or foreign corporations or financial
institutions, including debt securities of all types and maturities, convertible
securities and preferred stocks. The Fund also may purchase securities issued or
guaranteed by United States or foreign governments (including foreign states,
provinces and municipalities) or their agencies and instrumentalities
("governmental entities") or issued or guaranteed by international organizations
designated or supported by multiple governmental entities to promote economic
reconstruction or development ("supranational entities").

      International Investing. The Global Bond Focus Fund may invest in fixed
income securities denominated in any currency or multinational currency unit. An
illustration of a multinational currency unit is the European Currency Unit
("ECU"), which is a "basket" consisting of specified amounts of the currencies
of certain of the twelve member states of the European Community, a Western
European economic cooperative association including France, Germany, the
Netherlands and the United Kingdom. The specific amounts of currencies
comprising the ECU may be adjusted by the Council of Ministers of the European
Community to reflect changes in relative values of the underlying currencies.
The Investment Adviser does not believe that such adjustments will adversely
affect holders of ECU-denominated obligations or the marketability of such
securities. European supranational entities (described further below), in
particular, issue ECU-denominated obligations. The Fund may invest in securities
denominated in the currency of one nation although issued by a governmental
entity, corporation or financial institution of another nation. For example, the
Fund may invest in a British pound sterling-denominated obligation issued by a
United States corporation. Such investments involve credit risks associated with
the issuer and currency risks associated with the currency in which the
obligation is denominated. See "Other Investments and Risks" below.

      It is anticipated that under current conditions the Global Bond Focus Fund
will invest primarily in marketable securities denominated in the currencies of
the United States, Canada, Western European nations, New Zealand and Australia,
as well as in ECUs. Further, it is anticipated that such securities will be
issued primarily by entities located in such countries and by supranational
entities. Under normal conditions, the Fund's investments will be denominated in
at least three currencies or multinational currency units. Under certain adverse
conditions, the Fund may restrict the financial markets or currencies in which
its assets will be invested. The Fund presently intends to invest its assets
solely in the United States financial markets or United States
dollar-denominated obligations only for temporary defensive purposes.

      The obligations of foreign governmental entities have various kinds of
government support and include obligations issued or guaranteed by foreign
governmental entities with taxing power. These obligations may or may not be
supported by the full faith and credit of a foreign government. The Global Bond
Focus Fund will invest in foreign government securities of issuers considered
stable by the Investment Adviser. While investments in foreign 


                                        4
<PAGE>   53

government debt securities may involve special risks, the Investment Adviser
does not believe that the credit riskinherent in the obligations of stable
foreign governments is significantly greater than that of U.S. Government
securities. See "Other Portfolio Strategies -- Foreign Securities" in the
Appendix to this Prospectus.

      Supranational entities include international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Steel and Coal Community, the Asian
Development Bank and the Inter-American Development Bank. The government
members, or "stockholders," usually make initial capital contributions to the
supranational entity and in many cases are committed to make additional capital
contributions if the supranational entity is unable to repay its borrowings.

      Allocation of Investments. In seeking to meet its investment objective,
high current income will be only one of the factors that the Investment Adviser
will consider in selecting portfolio securities for the Global Bond Focus Fund.
As a general matter, in evaluating investments for the Fund, the Investment
Adviser will consider, among other factors, the relative levels of interest
rates prevailing in various countries, the potential appreciation of such
investments in their denominated currencies and, for debt instruments not
denominated in U.S. dollars, the potential movement in the value of such
currencies compared to the U.S. dollar. Additionally, the Fund, in seeking
capital appreciation, may invest in relatively low yielding instruments in
expectation of favorable currency fluctuations or interest rate movements,
thereby potentially reducing the Fund's current yield. In seeking income, the
Fund may invest in short term instruments with relatively high yields (as
compared to other debt securities) meeting the Fund's investment criteria,
notwithstanding that the Fund may not anticipate that such instruments will
experience substantial capital appreciation.

      The average maturity of the Global Bond Focus Fund's portfolio securities
will vary based upon the Investment Adviser's assessment of economic and market
conditions. As with all fixed income securities, changes in market yields will
affect the Fund's asset value as the prices of portfolio securities generally
increase when interest rates decline and decrease when interest rates rise.
Prices of longer-term securities generally fluctuate more in response to
interest rate changes than do shorter-term securities. The Global Bond Focus
Fund does not expect the average maturity of its portfolio to exceed ten years.

Other Investments and Risks

      In addition, the Global Bond Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The Fund
may invest in securities of foreign issuers. Investments in foreign securities,
particularly those of non-governmental issuers, involve considerations and risks
that are not ordinarily associated with investing in domestic issuers. These
considerations and risks include changes in currency rates, currency exchange
control regulations, the possibility of expropriation, confiscatory taxation,
high rates of inflation, the unavailability of financial information or the
difficulty of interpreting financial information prepared under foreign
accounting standards, less liquidity and more volatility in foreign securities
markets, the impact of political, social or diplomatic developments, and the
difficulty of assessing economic trends in foreign countries. In addition, net
investment income earned by the Fund on a foreign security may be subject to
withholding and other taxes imposed by foreign governments, which will reduce
the Fund's net investment income. The Global Bond Focus Fund may also from time
to time be substantially invested in non-dollar-denominated securities of
foreign issuers. The value of the Global Bond Focus Fund's holdings denominated
in currencies other than the U.S. dollar and the unrealized appreciation or
depreciation of those investments insofar as United States investors are
concerned will be affected by changes in the value of such currencies relative
to the U.S. dollar. Furthermore, the Fund's return on investments in non-
dollar-denominated securities may be reduced or enhanced as a result of changes
in foreign currency rates during the period in which the Fund holds such
investments. Such currency fluctuations may have a substantial impact on the
value of the Fund's holdings. The Fund may engage in transactions, such as
currency swaps and purchasing and selling options on currencies, for purposes of
hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the 


                                        5
<PAGE>   54

intention of hedging against adverse currency movements, transactions in such
instruments involve the risk that anticipated currency movements will not be
accurately predicted and that the Fund's hedging strategies will be ineffective
and may cause the Fund to realize losses. The Global Bond Focus Fund may also
invest in debt securities issued by foreign governments. See "Other Portfolio
Strategies -- Foreign Securities" in the Appendix and Annex B of the Appendix to
this Prospectus.

      The Global Bond Focus Fund is authorized to write (i.e., sell) and to
purchase call and put options on securities held in its portfolio or securities
indices the performance of which is substantially correlated with securities
held in its portfolio, may engage in transactions in futures and may invest in
securities the potential return of which is based on the change in particular
measurements of value or rate (i.e., indexed securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed securities, options and
futures.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Utility Focus Fund is to seek both
capital appreciation and current income through investment of at least 65% of
its total assets in equity and debt securities issued by domestic and foreign
companies which are, in the opinion of Merrill Lynch Asset Management, L.P. (the
"Investment Adviser"), primarily engaged in the ownership or operation of
facilities used to generate, transmit or distribute electricity,
telecommunications, gas or water. There can be no assurance that the Global
Utility Focus Fund will achieve its investment objective. The Fund may employ a
variety of instruments and techniques to enhance income and to hedge against
market and currency risk, as described in Annex B to the Appendix to this
Prospectus. Investing on an international basis involves special considerations.
See "Other Investments and Risks" below. The Fund should be considered a
long-term investment and a vehicle for diversification, and not as a balanced
investment program. The Fund may not be appropriate as the exclusive investment
to fund a variable annuity or variable life insurance contract ("Contract") for
all Contract owners.

      The Global Utility Focus Fund at all times, except during temporary
defensive periods, will maintain at least 65% of its total assets invested in
equity and debt securities issued by domestic and foreign companies in the
utilities industries. The Fund reserves the right to hold, as a temporary
defensive measure or as a reserve for redemptions, short-term U.S. Government
securities, money market securities, including repurchase agreements, or cash in
such proportions as, in the opinion of the Investment Adviser, prevailing market
or economic conditions warrant. Except during temporary defensive periods, such
securities or cash will not exceed 20% of its total assets. Under normal
circumstances, the Fund will invest at least 65% of its total assets in issuers
domiciled in at least three countries, one of which may be the United States,
although the Investment Adviser expects the Fund's portfolio to be more
geographically diversified. Under normal conditions, it is anticipated that the
percentage of assets invested in U.S. securities will be higher than that
invested in securities of any other single country. It is possible that at times
the Fund may have 65% or more of its total assets invested in foreign
securities.

      The Global Utility Focus Fund will invest in common stocks (including
preferred or debt securities convertible into common stocks), preferred stocks
and debt securities. The relative weightings among common stocks, debt
securities and preferred stocks will vary from time to time based upon the
Investment Adviser's judgment of the extent to which investments in each
category will contribute to meeting the Fund's investment objective. Fixed
income securities in which the Fund will invest generally will be limited to
those rated investment grade, that is, rated in one of the four highest rating
categories by Standard & Poor's Ratings Group ("Standard & Poor's") or Moody's
Investors Service, Inc. ("Moody's") (i.e., securities rated at least BBB by
Standard & Poor's or Baa by Moody's), or deemed to be of equivalent quality in
the judgment of the Investment Adviser. Securities rated Baa by Moody's are
described by it as having speculative characteristics and, according to Standard
& Poor's, fixed income securities rated BBB normally exhibit adequate protection
parameters, although adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to pay interest and repay principal.
The Fund's commercial paper investments at the time of purchase will be rated
"A-1" or "A-2" by Standard & Poor's or "Prime-1" or "Prime-2" by Moody's or, if
not rated, will be of comparable quality as determined by the Investment
Adviser. The Fund may also invest up to 5% of its total assets at the time of
purchase in fixed income securities having a minimum rating no lower than Caa by
Moody's or CCC by Standard & Poor's. The Fund may, but need not, dispose of any
security if it is subsequently downgraded. For a description of ratings of debt
securities, see Annex A to the Appendix to this Prospectus.

      A change in prevailing interest rates is likely to affect the Fund's net
asset value because prices of debt and equity securities of utility companies
tend to increase when interest rates decline and decrease when interest rates
rise.

      Utility Industries -- Description and Risks. Under normal circumstances,
the Global Utility Focus Fund will invest at least 65% of its total assets in
common stocks (including preferred or debt securities convertible into common
stocks), debt securities and preferred stocks of domestic and/or foreign
companies in the utility industries. To meet its objective of current income,
the Fund may invest in domestic utility companies that pay higher than average
dividends, but have a lesser potential for capital appreciation. The average
dividend yields of common stocks issued by domestic utility companies
historically have significantly exceeded those of industrial companies'


                                        4
<PAGE>   59

common stocks, while the prices of domestic utility stocks have tended to be
less volatile than stocks of industrial companies. The Investment Adviser
believes that the average dividend yields of common stocks issued by foreign
utility companies have also historically exceeded those of foreign industrial
companies' common stocks. To pursue its objective of capital appreciation, the
Fund may invest in foreign utility companies that pay lower than average
dividends, but have a greater potential for capital appreciation.

      The utility companies in which the Fund will invest include companies that
are, in the opinion of the Investment Adviser, primarily engaged in the
ownership or operation of facilities used to generate, transmit or distribute
electricity, telecommunications, gas or water.

      Investments in utility industries bear certain risks, including difficulty
in obtaining an adequate return on invested capital, difficulty in financing
large construction programs during an inflationary period, restrictions on
operations and increased cost and delays attributable to environmental
considerations and regulation, difficulty in raising capital in adequate amounts
on reasonable terms in periods of high inflation and unsettled capital markets,
technological innovations which may render existing plants, equipment or
products obsolete, the potential impact of natural or man-made disasters,
increased costs and reduced availability of certain types of fuel, occasionally
reduced availability and high costs of natural gas for resale, the effects of
energy conservation, the effects of a national energy policy and lengthy delays
and greatly increased costs and other problems associated with design,
construction, licensing, regulation and operation of nuclear facilities for
electric generation, including, among other considerations, the problems
associated with the use of radioactive materials and the disposal of radioactive
wastes. There are substantial differences between the regulatory practices and
policies of various jurisdictions, and any given regulatory agency may make
major shifts in policy from time to time. There is no assurance that regulatory
authorities will, in the future, grant rate increases or that such increases
will be adequate to permit the payment of dividends on common stocks.
Additionally, existing and possible future regulatory legislation may make it
even more difficult for these utilities to obtain adequate relief. Certain of
the issuers of securities in the portfolio may own or operate nuclear generating
facilities. Governmental authorities may from time to time review existing
policies, and impose additional requirements governing the licensing,
construction and operation of nuclear power plants.

      Utility companies in the United States and in foreign countries are
generally subject to regulation. In the United States, most utility companies
are regulated by state and/or federal authorities. Such regulation is intended
to ensure appropriate standards of service and adequate capacity to meet public
demand. Generally, prices are also regulated in the United States and in foreign
countries with the intention of protecting the public while ensuring that the
rate of return earned by utility companies is sufficient to allow them to
attract capital in order to grow and continue to provide appropriate services.
There can be no assurance that such pricing policies or rates of return will
continue in the future. The nature of regulation of the utility industries is
evolving both in the United States and in foreign countries. Changes in
regulation in the United States increasingly allow utility companies to provide
services and products outside their traditional geographic areas and lines of
business, creating new areas of competition within the industries. In some
instances, utility companies are operating on an unregulated basis. Because of
trends toward deregulation and the evolution of independent power producers as
well as new entrants to the field of telecommunications, non-regulated providers
of utility services have become a significant part of their respective
industries. The Investment Adviser believes that the emergence of competition
and deregulation will result in certain utility companies being able to earn
more than their traditional regulated rates of return, while others may be
forced to defend their core businesses from increased competition and may be
less profitable. The Investment Adviser seeks to take advantage of favorable
investment opportunities that are expected to arise from these structural
changes. Of course, there can be no assurance that favorable developments will
occur in the future.

      Foreign utility companies are also subject to regulation, although such
regulations may or may not be comparable to that in the United States. Foreign
utility companies may be more heavily regulated by their respective governments
than utilities in the United States and, as in the U.S., generally are required
to seek government approval for rate increases. In addition, many foreign
utilities use fuels that cause more pollution than those used in the United
States, which may require such utilities to invest in pollution control
equipment to meet any proposed pollution restrictions. Foreign regulatory
systems vary from country to country and may evolve in ways different from
regulation in the United States.


                                        5

      The principal sectors of the global utility industries are discussed
below.

      Electric. The electric utility industry consists of companies that are
engaged principally in the generation, transmission and sale of electric energy,
although many also provide other energy-related services. Domestic electric
utility companies, in general, recently have been favorably affected by lower
fuel and financing costs and the full or near completion of major construction
programs. In addition, certain of these companies generate cash flows in excess
of current operating expenses and construction expenditures, permitting some
degree of diversification into unregulated businesses. Some electric utilities
have also taken advantage of the right to sell power outside of their
traditional geographic areas. Electric utility companies have historically been
subject to the risks associated with increases in fuel and other operating
costs, high interest costs on borrowings needed for capital construction
programs, costs associated with compliance with environmental and safety
regulations and changes in the regulatory climate. As interest rates have
declined, many utilities have refinanced high cost debt and in doing so have
improved their fixed charges coverage. Regulators, however, have lowered allowed
rates of return as interest rates have declined and thereby caused the benefits
of the rate declines to be shared wholly or in part with customers.

      In the United States, the construction and operation of nuclear power
facilities is subject to increased scrutiny by, and evolving regulations of, the
Nuclear Regulatory Commission and state agencies having comparable jurisdiction.
Increased scrutiny might result in higher operating costs and higher capital
expenditures, with the risk that the regulators may disallow inclusion of these
costs in rate authorizations or the risk that a company may not be permitted to
operate or complete construction of a facility. In addition, operators of
nuclear power plants may be subject to significant costs for disposal of nuclear
fuel and for decommissioning of such plants.

      In October 1993, Standard & Poor's stiffened its debt-ratings formula for
the electric utility industry, stating that the industry is in long-term
decline. In addition, Moody's stated that it expected a drop in the next three
years in its average credit ratings for the industry. Reasons set forth for
these outlooks included slowing demand and increasing cost pressures as a result
of competition from rival providers.

      Telecommunications. The telephone industry is large and highly
concentrated. Companies that distribute telephone services and provide access to
the telephone networks comprise the greatest portion of this segment. Telephone
companies in the United States are still experiencing the effects of the breakup
of American Telephone & Telegraph Company, which occurred in 1984. Since 1984,
companies engaged in telephone communication services have expanded their
non-regulated activities into other businesses, including cellular telephone
services, data processing, equipment retailing, computer software and hardware
services, and financial services. This expansion has provided significant
opportunities for certain telephone companies to increase their earnings and
dividends at faster rates than had been allowed in traditional regulated
businesses. Increasing competition, technological innovations and other
structural changes, however, could adversely affect the profitability of such
utilities. Technological breakthroughs and the merger of telecommunications with
video and entertainment is now associated with the expansion of the role of
cable companies as providers of utility services in the telecommunications
industry and the competitive response of traditional telephone companies. Given
mergers and certain marketing tests currently underway, it is likely that both
traditional telephone companies and cable companies will soon provide a greatly
expanded range of utility services, including two-way video and informational
services.

      Gas. Gas transmission companies and gas distribution companies are also
undergoing significant changes. In the United States, interstate transmission
companies are regulated by the Federal Energy Regulatory Commission, which is
reducing its regulation of the industry. Many companies have diversified into
oil and gas exploration and development, making returns more sensitive to energy
prices. In the recent decades, gas utility companies have been adversely
affected by disruptions in the oil industry and have also been affected by
increased concentration and competition.

      Water. Water supply utilities are companies that collect, purify,
distribute and sell water. In the United States and around the world, the
industry is highly fragmented because most of the supplies are owned by local
authorities. Companies in this industry are generally mature and are
experiencing little or no per capita volume growth.

      Investment Outside the Utility Industries. The Global Utility Focus Fund
is permitted to invest up to 35% of its assets in securities of issuers that are
outside the utility industries. Such investments may include common stocks, debt
securities or preferred stocks and will be selected to meet the Fund's
investment objective of both capital appreciation and current income. These
securities may be issued by either U.S. or non-U.S. companies. Some of these
issuers may be in industries related to utility industries and, therefore, may
be subject to similar risks. Securities that are issued by foreign companies or
are denominated in foreign currencies are subject to certain risks. See "Other
Investments and Risks" below.

      The Global Utility Focus Fund is also permitted to invest in securities
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
and in securities issued or guaranteed by foreign governments. Foreign
government securities are typically denominated in foreign currencies and are
subject to the currency fluctuation and other risks of foreign securities
investments. The foreign government securities in which the Fund intends to
invest generally will consist of obligations supported by national, state or
local governments or similar political subdivisions. Foreign government
securities also include debt obligations of supranational entities, including
international organizations designated or supported by governmental entities to
promote economic reconstruction or development and international banking
institutions and related government agencies. Examples include the International
Bank for Reconstruction and Development (the "World Bank"), the European
Investment Bank, the Asian Development Bank and the Inter-American Development
Bank.

      Foreign government securities also include debt securities of
"quasi-governmental agencies" and debt securities denominated in multinational
currency units. An example of a multinational currency unit is the European
Currency Unit. A European Currency Unit represents specified amounts of the
currencies of certain of the twelve member states of the European Economic
Community. Debt securities of quasi-governmental agencies are issued by entities
owned by either a national or local government or are obligations of a political
unit that is not backed by the national government's full faith and credit and
general taxing powers. Foreign government securities will not be considered
government securities for purposes of determining the Fund's compliance with
diversification and concentration policies.

Other Investments and Risks

      In addition, the Global Utility Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The Global
Utility Focus Fund may also invest in securities of foreign issuers. Investments
in foreign securities, particularly those of non-governmental issuers, involve
considerations and risks that are not ordinarily associated with investing in
domestic issuers. These considerations and risks include changes in currency
rates, currency exchange control regulations, the possibility of expropriation,
confiscatory taxation, high rates of inflation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of political, social or diplomatic
developments, and the difficulty of assessing economic trends in foreign
countries. In addition, net investment income earned by the Fund on a foreign
security may be subject to withholding and other taxes imposed by foreign
governments which will reduce the Fund's net investment income. The Global
Utility Focus Fund may from time to time be substantially invested in
non-dollar-denominated securities of foreign issuers. Changes in the foreign
currency exchange rates may affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. The Global Utility Focus Fund may also engage in transactions, such
as currency swaps and purchasing and selling options on currencies, for purposes
of hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the intention of hedging against adverse currency movements,
transactions in such instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the Fund's hedging
strategies will be ineffective and may cause the Fund to realize losses. See
"Other Portfolio Strategies -- Foreign Securities" in the Appendix to this
Prospectus.

      The Global Utility Focus Fund may from time to time enter into standby
commitment agreements, engage in transactions in futures, invest in securities
the potential return of which is based on the change in particular measurements
of value or rate (i.e. indexed securities), and, is authorized to write (i.e.,
sell) call and put options and purchase put options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio, and to purchase put options on
securities held in its portfolio.

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the International Equity Focus Fund are to
seek capital appreciation and, secondarily, income by investing in a diversified
portfolio of equity securities of issuers located in countries other than the
United States. Under normal conditions, at least 65% of the Fund's net assets
will be invested in such equity securities and at least 65% of the Fund's total
assets will be invested in the securities of issuers from at least three
different foreign countries. The investment objective of the Fund is a
fundamental policy and may not be changed without approval of a majority of the
Fund's outstanding shares. There can be no assurance that the International
Equity Focus Fund will achieve its investment objectives. The Fund may employ a
variety of investments and techniques to hedge against market and currency risk.
See Annex B of the Appendix to this Prospectus. Investing on an international
basis involves special considerations. Investing in smaller capital markets
entails the risk of significant volatility in the Fund's security prices. The
Fund is designed for investors seeking to complement their U.S. holdings through
foreign investments. The Fund should be considered a long-term investment and a
vehicle for diversification, and not as a balanced investment program. The Fund
may not be appropriate as the exclusive investment to fund a variable annuity or
variable life insurance contract ("Contract") for all Contract owners.

      The International Equity Focus Fund will invest in an international
portfolio of securities of foreign companies located throughout the world. While
there are no prescribed limits on the geographic allocation of the Fund's
investments, management of the Fund anticipates that a substantial portion of
its assets will be invested in the developed countries of Europe and the Far
East. For the reasons stated below, management of the Fund will give special
attention to investment opportunities in the developing countries of the world,
including, but not limited to Latin America, the Far East and Eastern Europe. It
is anticipated that a significant portion of the Fund's assets may be invested
in such developing countries.

      The allocation of the International Equity Focus Fund's assets among the
various foreign securities markets will be determined by Merrill Lynch Asset
Management, L.P. (the "Investment Adviser") based primarily on its assessment of
the relative condition and growth potential of the various economies and
securities markets, currency and taxation considerations and other pertinent
financial, social, national and political factors. Within such allocations, the
Investment Adviser will seek to identify equity investments in each market that
are expected to provide a total return that equals or exceeds the return of such
market as a whole.

      A significant portion of the International Equity Focus Fund's assets may
be invested in developing countries. This allocation of the Fund's assets
reflects the belief that attractive investment opportunities may result from an
evolving long-term international trend favoring more market-oriented economies,
a trend that may especially benefit certain developing countries with smaller
capital markets. This trend may be facilitated by local or international
political, economic or financial developments that could benefit the capital
markets of such countries. Certain such countries, particularly so-called
"emerging" countries (such as Malaysia, Mexico and Thailand), which may be in
the process of developing more market-oriented economies, may experience
relatively high rates of economic growth. Because of the general illiquidity of
the capital markets in certain developing countries, the Fund may invest in a
relatively small number of leading or relatively actively traded companies in
the capital markets of such a country in the expectation that the investment
experience of the securities of such companies will substantially represent the
investment experience of that country's capital markets as a whole.

      While the International Equity Focus Fund will primarily emphasize
investments in common stock, the Fund may also invest in preferred stocks,
convertible debt securities and other instruments the return on which is linked
to the performance of a common stock or a basket or index of common stocks
(collectively, "equity securities"). The Fund may also invest in non-equity
securities, including debt securities, cash or cash equivalents denominated in
U.S. dollars or foreign currencies and short-term securities, including money
market instruments. Under certain adverse investment conditions, for defensive
purposes, the Fund may restrict the markets in which its assets will be invested
and may increase the proportion of assets invested in short-term obligations of
U.S. issuers. Investments made for defensive purposes will be maintained only
during periods in which the Investment Adviser determines that economic or
financial conditions are adverse for holding or being fully invested in equity
securities of foreign issuers.


                                        4
<PAGE>   67

      The International Equity Focus Fund also may invest up to 35% of its net
assets in longer-term, non-convertible debt securities emphasizing debt
securities which offer the opportunity for capital appreciation. Capital
appreciation in debt securities may arise as a result of a favorable change in
relative foreign exchange rates, in relative interest rate levels, or in the
creditworthiness of issuers. In accordance with its investment objective, the
Fund will not seek to benefit from anticipated short-term fluctuations in
currency exchange rates. The Fund may, from time to time, invest in debt
securities with relatively high yields (as compared to other debt securities
meeting the Fund's investment criteria), notwithstanding that the Fund may not
anticipate that such securities will experience substantial capital
appreciation. Such income can be used, however, to offset the operating expenses
of the Fund.

      The International Equity Focus Fund may invest in debt securities issued
or guaranteed by foreign governments (including foreign states, provinces and
municipalities) or their agencies and instrumentalities ("governmental
entities"), issued or guaranteed by international organizations designated or
supported by multiple foreign governmental entities (which are not obligations
of foreign governments) to promote economic reconstruction or development
("supranational entities"), or issued by foreign corporations or financial
institutions.

      Supranational entities include international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Steel and Coal Community, the Asian
Development Bank and the Inter-American Development Bank. The governmental
members, or "stockholders," usually make initial capital contributions to the
supranational entity and in many cases are committed to make additional capital
contributions if the supranational entity is unable to repay its borrowings.

Other Investments and Risks

      In addition, the International Equity Focus Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended,
and which therefore may be subject to restrictions on their transfer or resale.

      The International Equity Focus Fund has established no rating criteria for
the debt securities in which it may invest, and such securities may not be rated
at all for creditworthiness. Securities rated in the medium to lower rating
categories of nationally recognized statistical rating organizations and unrated
securities of comparable quality are predominantly speculative with respect to
the capacity to pay interest and repay principal in accordance with the terms of
the security and generally involve a greater volatility of price than securities
in higher rating categories. In purchasing such securities, the Fund will rely
on the Investment Adviser's judgment, analysis and experience in evaluating the
creditworthiness of an issuer of such securities. The Investment Adviser will
take into consideration, among other things, the issuer's financial resources,
its sensitivity to economic conditions and trends, its operating history, the
quality of the issuer's management and regulatory matters. The Fund does not
intend to purchase debt securities that are in default or that the Investment
Adviser believes will be in default. See "Risks of High Yield Securities" in the
Appendix to this Prospectus.

      The Fund may invest in securities of foreign issuers. Investments in
foreign securities, particularly those of non-governmental issuers, involve
considerations and risks that are not ordinarily associated with investing in
domestic issuers. These considerations and risks include changes in currency
rates, currency exchange control regulations, the possibility of expropriation,
confiscatory taxation, high rates of inflation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of political, social or diplomatic
developments, and the difficulty of assessing economic trends in foreign
countries. In addition, net investment income earned by the Fund on a foreign
security may be subject to withholding and other taxes imposed by foreign
governments, which will reduce the Fund's net investment income. The Fund may
from time to time be substantially invested in non-dollar-denominated securities
of foreign issuers. Changes in foreign currency exchange rates may affect the
value of securities in the portfolio and the unrealized appreciation or
depreciation of investments insofar as United States investors are concerned.
Furthermore, the Fund's return on investments in non- dollar-denominated
securities may be reduced or enhanced as a result of changes in foreign currency
rates during


                                        5
<PAGE>   68

the period in which the Fund holds such investments. See "Other Portfolio
Strategies -- Foreign Securities" in the Appendix to this Prospectus.

            The International Equity Focus Fund may engage in transactions, such
as currency swaps and purchasing and selling options on currencies, for purposes
of hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the intention of hedging against adverse currency movements,
transactions in such instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the International Equity
Focus Fund's hedging strategies will be ineffective and may cause the Fund to
realize losses.

            The International Equity Focus Fund may also invest a significant
portion of its assets in securities of foreign issuers in smaller capital
markets. Foreign investments involve risks that are often heightened for
investments in smaller capital markets. There may be less publicly available
information about an issuer in a smaller capital market than would be available
about a United States company, and it may not be subject to accounting, auditing
and financial reporting standards and requirements comparable to those of United
States companies. Furthermore, smaller capital markets have substantially less
volume than United States markets so securities in many smaller capital markets
are less liquid and their prices may be more volatile than securities of
comparable United States companies. As a result, traditional investment
measurements, such as price/earnings ratios, as used in the United States, may
not be applicable in certain capital markets. See "Other Portfolio Strategies --
Foreign Securities" in the Appendix to this Prospectus.

            The International Equity Focus Fund is also authorized to write
(i.e., sell) and purchase call and put options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio, engage in transactions in
futures and options thereon, and may invest in securities the potential return
of which is based on the change in particular measurements of value or rate
(i.e. indexed and inverse securities).

            A further discussion of the foregoing investments and the risks
associated with such investments is set forth in the Appendix to this
Prospectus, including Annex B of the Appendix to this Prospectus, which includes
a discussion of certain portfolio strategies relating to indexed and inverse
securities, options, futures and foreign exchange transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Developing Capital Markets Focus Fund is
to seek long-term capital appreciation by investing in securities, principally
equities, of issuers in countries having smaller capital markets. Under normal
conditions, at least 65% of the Fund's net assets will be invested in such
equity securities. The investment objective of the Fund is a fundamental policy
and may not be changed without approval of a majority of the Fund's outstanding
shares. There can be no assurance that the Fund will achieve its investment
objective. The Developing Capital Markets Focus Fund may employ a variety of
investments and techniques to hedge against market and currency risk. See Annex
B to the Appendix to this Prospectus. Investing on an international basis
involves special considerations. Investing in smaller capital markets entails
the risk of significant volatility in the Fund's security prices. See "Other
Investments and Risks" below. The Developing Capital Markets Focus Fund is
designed for investors seeking to complement their U.S. holdings through foreign
investments. The Fund should be considered a long-term investment and a vehicle
for diversification, and not as a balanced investment program. The Fund may not
be appropriate as the exclusive investment to fund a variable annuity or
variable life insurance contract ("Contract") for all Contract owners.

      For purposes of its investment objective, the Developing Capital Markets
Focus Fund considers countries having smaller capital markets to be all
countries other than the four countries having the largest equity market
capitalizations. Currently, these four countries are Japan, the United Kingdom,
the United States and Germany. At December 31, 1997, those countries' equity
market capitalizations totalled approximately [ ]% of the world's equity market
capitalization according to data provided by Morgan Stanley Capital
International. The Fund will at all times, except during defensive periods,
maintain investments in at least three countries having smaller capital markets.

      The Developing Capital Markets Focus Fund seeks to benefit from economic
and other developments in smaller capital markets. The investment objective of
the Fund reflects the belief that investment opportunities may result from an
evolving long-term international trend favoring more market-oriented economies,
a trend that may especially benefit certain countries having smaller capital
markets. This trend may be facilitated by local or international political,
economic or financial developments that could benefit the capital markets of
such countries. Certain such countries, particularly so-called "emerging"
countries (such as Malaysia, Mexico and Thailand) which may be in the process of
developing more market-oriented economies, may experience relatively high rates
of economic growth. Other countries (such as France, the Netherlands and Spain),
although having relatively mature smaller capital markets, may also be in a
position to benefit from local or international developments encouraging greater
market orientation and diminishing governmental intervention in economic
affairs.

      Many investors, particularly individuals, lack the information, capability
or inclination to invest in countries having smaller capital markets. It also
may not be permissible for such investors to invest directly in certain such
markets. Unlike many intermediary investment vehicles, such as closed-end
investment companies that invest in a single country, the Fund intends to
diversify investment risk among the capital markets of a number of countries.
The Fund will not necessarily seek to diversify investments on a geographical
basis or on the basis of the level of economic development of any particular
country.

      In its investment decision-making, Merrill Lynch Asset Management, L.P.
(the "Investment Adviser") will emphasize the allocation of assets among certain
countries' capital markets, rather than the selection of particular industries
or issuers. Because of the general illiquidity of the capital markets in some
countries, the Fund may invest in a relatively small number of leading or
actively traded companies in a country's capital markets in the expectation that
the investment experience of the securities of such companies will substantially
represent the investment experience of the country's capital markets as a whole.

      The Developing Capital Markets Focus Fund also may invest in debt
securities of issuers in countries having smaller capital markets. Capital
appreciation in debt securities may arise as a result of a favorable change in
relative foreign exchange rates, in relative interest rate levels, or in the
creditworthiness of issuers. In accordance with its investment objective, the
Fund will not seek to benefit from anticipated short-term fluctuations in
currency exchange rates. The Fund may, from time to time, invest in debt
securities with relatively high yields (as compared


                                        4
<PAGE>   73

to other debt securities meeting the Fund's investment criteria),
notwithstanding that the Fund may not anticipate that such securities will
experience substantial capital appreciation. See "Other Investments and Risks"
below. Such income can be used, however, to offset the operating expenses of the
Fund.

      The Developing Capital Markets Focus Fund may invest in debt securities
issued or guaranteed by foreign governments (including foreign states, provinces
and municipalities) or their agencies and instrumentalities ("governmental
entities"), issued or guaranteed by international organizations designated or
supported by multiple foreign governmental entities (which are not obligations
of foreign governments) to promote economic reconstruction or development
("supranational entities"), or issued by foreign corporations or financial
institutions.

      Supranational entities include international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Steel and Coal Community, the Asian
Development Bank and the Inter-American Development Bank. The governmental
members, or "stockholders," usually make initial capital contributions to the
supranational entity and in many cases are committed to make additional capital
contributions if the supranational entity is unable to repay its borrowings.

      For purposes of the Developing Capital Markets Focus Fund's investment
objective, an issuer ordinarily will be considered to be located in the country
where the primary trading market of its securities is located. The Fund,
however, may consider a company to be located in countries having smaller
capital markets, without reference to its domicile or to the primary trading
market of its securities, when at least 50% of its non-current assets,
capitalization, gross revenues or profits in any one of the two most recent
fiscal years represents (directly or indirectly through subsidiaries) assets or
activities located in such countries. The Fund also may consider closed-end
investment companies to be located in the country or countries in which they
primarily make their portfolio investments.

      The Developing Capital Markets Focus Fund may invest a significant portion
of its assets in securities of foreign issuers in smaller capital markets.
Foreign investments involve risks, which are often heightened for investments in
smaller capital markets, including fluctuations in foreign exchange rates,
future political and economic developments, different legal systems and the
existence or possible imposition of exchange controls or other foreign or United
States governmental laws or restrictions applicable to such investments. With
respect to certain countries, there may be the possibility of expropriation of
assets, confiscatory taxation, high rates of inflation, political or social
instability or diplomatic developments which could affect investment in those
countries. In addition, certain foreign investments may be subject to foreign
withholding taxes. See "Other Investments and Risks" below.

      There may be less publicly available information about an issuer in a
smaller capital market than would be available about a United States company,
and it may not be subject to accounting, auditing and financial reporting
standards and requirements comparable to those of United States companies. As a
result, traditional investment measurements, such as price/earnings ratios, as
used in the United States, may not be applicable in certain capital markets.
Furthermore, smaller capital markets have substantially less volume than United
States markets so securities in many smaller capital markets are less liquid and
their prices may be more volatile than securities of comparable United States
companies. See "Other Portfolio Strategies -- Foreign Securities" in the
Appendix to this Prospectus.

Other Investments and Risks

      In addition, the Fund may purchase certain securities that are not
registered under the Securities Act of 1933, as amended, and which therefore may
be subject to restrictions on their transfer or resale.

      The Developing Capital Markets Focus Fund has established no rating
criteria for the debt securities in which it may invest, and such securities may
not be rated at all for creditworthiness. Securities rated in the medium to
lower rating categories of nationally recognized statistical rating
organizations and unrated securities of


                                        5
<PAGE>   74

comparable quality are predominantly speculative with respect to the capacity to
pay interest and repay principal in accordance with the terms of the security
and generally involve a greater volatility of price than securities in higher
rating categories. In purchasing such securities, the Fund will rely on the
Investment Adviser's judgment, analysis and experience in evaluating the
creditworthiness of an issuer of such securities. The Investment Adviser will
take into consideration, among other things, the issuer's financial resources,
its sensitivity to economic conditions and trends, its operating history, the
quality of the issuer's management and regulatory matters. The Fund does not
intend to purchase debt securities that are in default or which the Investment
Adviser believes will be in default. See "Risks of High Yield Securities" in the
Appendix to this Prospectus.

      The Developing Capital Markets Focus Fund invests in securities of foreign
issuers. Investments in foreign securities, particularly those of
non-governmental issuers, involve considerations and risks that are not
ordinarily associated with investing in domestic issuers. These considerations
and risks include changes in currency rates, currency exchange control
regulations, the possibility of expropriation, confiscatory taxation, high rates
of inflation, the unavailability of financial information or the difficulty of
interpreting financial information prepared under foreign accounting standards,
less liquidity and more volatility in foreign securities markets, the impact of
political, social or diplomatic developments, and the difficulty of assessing
economic trends in foreign countries. In addition, net investment income earned
by the Fund on a foreign security may be subject to withholding and other taxes
imposed by foreign governments, which will reduce the Fund's net investment
income. The Fund may from time to time be substantially invested in
non-dollar-denominated securities of foreign issuers. Changes in foreign
currency exchange rates may affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. See "Other Portfolio Strategies -- Foreign Securities" in the
Appendix to this Prospectus.

      The Developing Capital Markets Focus Fund may engage in transactions, such
as currency swaps and purchasing and selling options on currencies, for purposes
of hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the intention of hedging against adverse currency movements,
transactions in such instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the Fund's hedging
strategies will be ineffective and may cause the Fund to realize losses.

      The Developing Capital Markets Focus Fund may from time to time enter into
standby commitment agreements and is authorized to write (i.e., sell) and
purchase call and put options on securities held in its portfolio or securities
indices the performance of which is substantially correlated with securities
held in its portfolio, may engage in transactions in futures and may invest in
securities the potential return of which is based on the change in particular
measurements of value or rate (i.e., indexed and inverse securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed and inverse securities,
options, futures and foreign exchange transactions.

#  On December 6, 1996, the Government Bond Fund (i) implemented a change in
   its investment objective so that the Fund may invest in any debt
   securities issued or guaranteed by the U.S. Government, its agencies or
   instrumentalities without regard to remaining maturity and (ii) changed
   its name from the Intermediate Government Bond Fund to its current name.
   For the period from the commencement of the Fund's operations through
   December 6, 1996, the portfolio of the Fund consisted primarily of
   intermediate-term debt securities issued or guaranteed by the U.S.
   Government, its agencies or instrumentalities with a maximum maturity not
   to exceed fifteen years.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Government Bond Fund is to seek the
highest possible current income consistent with the protection of capital
afforded by investing in debt securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities. Under normal circumstances, all
or substantially all of the Fund's assets will be invested in such securities.
Depending on market conditions, an average maturity of six to fifteen years is
anticipated. When, in the opinion of management, prevailing market or economic
conditions warrant, a portion of the Fund may be invested in money market
securities or a liquid asset fund to effectively utilize cash reserves. There
can be no assurance that the Government Bond Fund will achieve its investment
objective.

      Certain of the securities in which the Government Bond Fund invests are
supported by the full faith and credit of the U.S. Government, such as U.S.
Treasury obligations. Other of the securities in which the Fund invests are not
supported by the full faith and credit of the U.S. Government but are issued by
U.S. Government agencies, instrumentalities or government-sponsored enterprises.
Such securities are generally supported only by the credit of the agency,
instrumentality or enterprise issuing the security and are generally considered
to have a low principal risk. However, because of the longer-term maturities of
the securities in which the Fund will invest, interest rate fluctuations may
adversely affect the market value of such securities. As interest rates rise,
the value of fixed-income securities will fall, adversely affecting the net
asset value of the Fund. The Fund should be considered a long-term investment
and a vehicle for diversification, and not as a balanced investment program. The
Fund may not be appropriate as the exclusive investment to fund a variable
annuity or variable life insurance contract ("Contract") for all Contract
owners.

      The U.S. Treasury Department has enacted regulations prescribing
diversification standards to be met by investment company portfolios to which
the investment base for any variable annuity policy has been allocated as a
condition to such policies being treated as variable annuity contracts under the
Internal Revenue Code of 1986, as amended. The regulations limit the percentage
of the total assets of any investment company portfolio which may be invested in
securities of any five or fewer issuers, including a requirement that no more
than 55% of a portfolio's total assets be invested in the securities of any one
issuer. Direct obligations of the U.S. Treasury are not excepted from the
diversification requirements. Each government agency or instrumentality issuing,
guaranteeing or insuring securities will be treated as a separate issuer for
purposes of the diversification standards.

      In addition, the Government Bond Fund may purchase certain securities that
are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale. The Fund
may also invest in securities the potential return of which is based on the
change in particular measurements of value or rate (i.e., indexed securities). A
further discussion of the investments described in this paragraph and the risks
associated with such investments is set forth in the Appendix to this
Prospectus, including Annex B of the Appendix to this Prospectus, which includes
a discussion of certain portfolio strategies relating to indexed securities.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Index 500 Fund is to seek to provide
investment results that, before expenses, correspond to the aggregate price and
yield performance of the S&P 500 Index. There can be no assurance that the Fund
will achieve its investment objective. The Fund should be considered a long-term
investment and a vehicle for diversification, and not as a balanced investment
program. The Fund may not be appropriate as the exclusive investment to fund a
variable annuity or variable life insurance contract ("Contract") for all
Contract owners.

      The S&P 500 Index is a market-weighted index composed of 500 common stocks
issued by companies in a wide range of businesses and which collectively
represent a substantial portion of all common stocks publicly traded in the U.S.
The composition of the S&P 500 Index is determined by Standard & Poor's Rating
Group ("Standard & Poor's"), a division of the McGraw-Hill Companies, Inc.
Standard & Poor's criteria for selecting common stocks to include in the S&P 500
Index is based on factors such as market capitalization, trading activity and
the adequacy of representation of particular industries, and favors U.S.-traded
stocks of large companies that are among the most dominant in their industries.
The S&P 500 Index is generally considered broadly representative of the
performance of large-capitalization publicly traded common stocks in the U.S.
The inclusion of a stock in the S&P 500 Index does not imply that Standard &
Poor's believes the stock to be an attractive investment.

      The Index 500 Fund will not attempt to buy or sell securities based on
Merrill Lynch Asset Management, L.P.'s (the "Investment Adviser") economic,
financial or market analysis, but will instead employ a "passive" approach that
attempts to remain invested at all times in a portfolio of assets the
performance of which is expected to be strongly correlated with that of the S&P
500 Index. The Index 500 Fund may invest in all 500 stocks in the S&P 500 Index
in approximately the same proportions as their weightings in the S&P 500 Index,
or may invest in a statistically selected sample of the 500 stocks which
comprise the S&P 500 Index designed, based on market capitalizations, industry
weightings and financial attributes, to have aggregate investment
characteristics similar to those of the S&P 500 Index as a whole. The Index 500
Fund may also (i) purchase common stocks not included in the S&P 500 Index as a
proxy for certain common stocks included in the S&P 500 Index when the
Investment Adviser believes it is an efficient means of replicating the
performance of that index to do so, and (ii) invest in options and future
contracts linked to the performance of the S&P 500 Index or of common stocks
represented in the index.

      Under normal circumstances, it is expected that the Index 500 Fund will
invest at least 90% (65% if the Index 500 Fund's assets are below $20 million)
of its assets in common stocks represented in the S&P 500 Index and related
options and futures contracts. The Index 500 Fund may invest a substantial
portion of its assets in options and futures contracts in order to gain market
exposure efficiently in the event of subscriptions, to maintain liquidity in the
event of redemptions and to minimize trading costs. The Index 500 Fund may also
invest in short-term fixed income instruments as cash reserves. The Index 500
Fund will not invest in short-term fixed income instruments, options or futures
contracts for the purpose of implementing a defensive market strategy by
lowering the Fund's exposure to common stocks to protect against a potential
stock market decline, but instead will attempt to remain fully invested without
regard to the Investment Adviser's market analysis. The Fund may, however, hold
short-term fixed income instruments for temporary cash management purposes.

      The foregoing investment techniques are expected to be an effective means
of substantially duplicating the aggregate price and yield performance of the
S&P 500 Index at such times when the Index 500 Fund is not fully invested in all
500 stocks in the S&P 500 Index in approximately the same proportions as their
weightings in that index. To the extent the Index 500 Fund utilizes the
foregoing investment techniques, the Fund may not track the S&P 500 Index with
the same degree of accuracy as the Fund would if it were fully invested in all
500 stocks in the S&P 500 Index in approximately the same proportions as their
weightings in that index. However, the principal advantage of the foregoing
investment techniques is to provide an efficient means to invest in the universe
of stocks of the S&P 500 Index. The Fund is expected to provide broad
diversification, and will seek to operate at low costs due to its "passive"
approach to portfolio management and anticipated low portfolio turnover rate.

      In addition, the Index 500 Fund may purchase certain securities that are
not registered under the Securities Act of 1933, as amended, and which therefore
may be subject to restrictions on their transfer or resale. The Index 500 Fund
may also invest in securities of foreign issuers to the extent such issuers are
included in the S&P 500 Index. See "Other Portfolio Strategies -- Foreign
Securities" in the Appendix to this Prospectus. The Fund is also authorized to
write (i.e., sell) and purchase call and put options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio and may engage in transactions
in futures and may invest in securities the potential return of which is based

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Growth Focus Fund is to seek
long-term growth of capital. The Global Growth Focus Fund will seek to achieve
its investment objective by investing in a diversified portfolio of equity
securities of issuers located in various foreign countries and the United
States, placing particular emphasis on companies that have exhibited
above-average growth rates in earnings. The Fund may be appropriate only for
long-term investors who can assume the risk of loss of principal, and do not
seek current income. There can be no assurance that the Global Growth Focus Fund
will achieve its investment objective. The Global Growth Focus Fund may employ a
variety of techniques, including derivative investments, in connection with
certain trading strategies, including to hedge against market and currency risk,
to enhance total return or to gain exposure to equity markets. See Annex B of
the Appendix to this Prospectus. Investments on an international basis in
foreign securities markets involve risks and special considerations not
typically associated with investments in securities of United States issuers.
See "Other Investments and Risks" below. The Fund should be considered a
long-term investment and a vehicle for diversification, and not as a balanced
investment program.

      Issuers may achieve above-average growth rates in earnings from a variety
of factors including, but not limited to, above-average growth rates in sales,
profit margin improvement, proprietary or niche products or services, leading
market shares, and underlying strong industry growth. Management of the Fund
believes that companies which possess above-average earnings growth frequently
provide the prospect of above-average stock market returns, although such
companies tend to have higher relative stock market valuations. Emphasis also
will be given to companies having medium to large stock market capitalizations
($2 billion or more). Investment in companies with lower market capitalizations,
especially those under $1 billion, may involve special risks including limited
product lines, market or financial resources or a limited management group. In
addition, many smaller company stocks trade less frequently and in smaller
volume, and may be subject to more abrupt or erratic price movements or may be
more sensitive to market fluctuations, than stocks of larger companies.

      The Global Growth Focus Fund will emphasize investments in equity
securities, primarily common stock, and, to a lesser extent, securities
convertible into common stock, preferred stock, rights to subscribe for common
stock and other investments the return on which is determined by the performance
of a common stock or a basket or index of common stocks. Under normal market
conditions, at least 65% of the Fund's total assets will be invested in equity
securities of issuers from at least three different countries. The Fund reserves
the right, as a defensive measure and to provide for redemptions, to hold other
types of securities, including non-convertible preferred stocks and debt
securities rated investment grade by a nationally recognized statistical rating
organization, U.S. Government and money market securities, including repurchase
agreements, or cash, in such proportions, including up to 100%, as in the
opinion of Merrill Lynch Asset Management L.P. (the "Investment Adviser")
prevailing market or economic conditions warrant.

Other Investments and Risks

      In addition, the Global Growth Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale.

      Because a substantial portion of the Fund's assets may be invested in
securities of non-U.S. issuers, an investor in the Fund should be aware of
certain risk factors and special considerations relating to international
investing, which may involve risks that are not typically associated with
investments in the securities of U.S. issuers. Investing on an international
basis involves certain risks not involved in domestic investments, including
fluctuations in foreign exchange rates, future political and economic
developments, different legal systems and the possible imposition of exchange
controls or other foreign governmental laws or restrictions. Securities prices
in different countries are subject to different economic, financial, political
and social factors. Since the Fund invests heavily in securities denominated or
quoted in currencies other than the U.S. dollar, changes in foreign currency
exchange rates will affect the value of securities in the Fund and the
unrealized appreciation or depreciation of investments. Currencies of certain
countries may be volatile and therefore may affect the value of securities
denominated in such currencies. In addition, with respect to certain foreign
countries, there is the possibility of expropriation of assets,


                                        3
<PAGE>   87

confiscatory taxation, difficulty in obtaining or enforcing a court judgment,
economic, political or social instability or diplomatic developments that could
affect investments in those countries. Moreover, individual foreign economies
may differ favorably or unfavorably from the U.S. economy in such respects as
growth of gross domestic product, rates of inflation, capital reinvestment,
resources, self-sufficiency and balance of payments position. Certain foreign
investments also may be subject to foreign withholding taxes, These risks often
are heightened for investments in smaller, emerging capital markets. For
additional information concerning the risks of investing in foreign securities.
See "Other Portfolio Strategies -- Foreign Securities" in the Appendix to this
Prospectus.

      The Global Growth Focus Fund may also engage in transactions, such as
currency swaps and purchasing and selling options on currencies, for purposes of
hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the U.S. dollar. The Fund is also authorized to
write (i.e., sell) and purchase both call and put options on securities held in
its portfolio, securities indices the performance of which is substantially
correlated with securities held in its portfolio or on securities it intends to
purchase and may also invest in futures and in securities the potential return
of which is based on the change in particular measurements of value or rate
(i.e., indexed securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed securities, options, futures
and foreign exchange transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The Capital Focus Fund's investment objective is to achieve the highest
total investment return consistent with prudent risk. To do this, management of
the Fund shifts the emphasis among equity, debt (including money market) and
convertible securities. This flexible, total investment return approach is
called a "fully managed" investment policy. It distinguishes the Capital Focus
Fund from other investment companies, which often seek either capital growth or
current income. This approach permits management of the Fund to vary investment
policy based on its evaluation of changes in economic and market trends. Total
investment return is the aggregate of income and capital value changes.
Consistent with this policy, the Capital Focus Fund's portfolio may, at any
given time, be invested substantially in equity securities, corporate bonds or
money market securities. It is the expectation of management that, over longer
periods, a major portion of the Fund's portfolio will consist of equity
securities of larger market capitalization, quality companies. There can be no
assurance that the Fund will achieve its investment objective. The Capital Focus
Fund may employ a variety of investments and techniques to hedge against market
and currency risk. See Annex B to the Appendix to this Prospectus

      The Capital Focus Fund's investment philosophy is based on the belief
that, as in the past, the structure of the United States' economy and the
economies and securities markets of other countries will undergo continuous
change. Thus, the fully managed approach puts maximum emphasis on investment
flexibility. The two principal features of the Fund's management approach are
flexibility and concentration in "quality" companies.

      Flexibility. The Capital Focus Fund's fully managed investment approach
makes use of equity, debt (including money market) and convertible securities.
Freedom to move among these different types of securities as prevailing trends
change is the keystone of the Fund's investment policy.

      Concentration in "Quality" Companies. The earnings of quality companies
generally tend to grow consistently. Their internal strengths -- good financial
resources, a strong balance sheet, satisfactory rate of return on capital, a
good industry position and superior management skills -- give the Fund
confidence that these companies consistently will perform at high levels. The
Fund considers quality companies to be those that conform most closely to these
characteristics. Most of the Fund's equity portfolio is in the common stocks of
these quality companies.

      Sometimes, to reduce risk and to achieve the highest total investment
return, the Capital Focus Fund may invest in other securities:

      o Non-convertible, long-term debt securities, including "deep discount"
corporate debt securities, mortgage-backed securities issued or guaranteed by
governmental entities or private issuers, and debt securities issued or
guaranteed by governments, their agencies and instrumentalities. Such debt
securities generally will be "investment grade." However, the Fund has
established no rating criteria for the debt securities in which it may invest,
and the Fund may invest in securities that are rated below Baa by Moody's
Investors Service, Inc. ("Moody's") or below BBB by Standard & Poor's Ratings
Services ("S&P") or which, in the judgment of Merrill Lynch Asset Management,
L.P. (the "Investment Adviser") possess similar credit characteristics. Such
securities, sometimes referred to as "high yield/high risk securities" or "junk
bonds", are predominantly speculative with respect to the capacity to pay
interest and repay principal in accordance with the terms of the security and
generally involve a greater volatility of price than securities in higher rating
categories. See "Other Investment and Risks" below and "Risks of High Yield
Securities" in the Appendix to this Prospectus. The Fund does not intend to
purchase debt securities that are in default or which the Investment Adviser
believes will be in default. The Fund does not intend to invest in excess of 35%
of its total assets in securities that are rated below Baa by Moody's or below
BBB by S&P or that the Investment Adviser believes have characteristics similar
to those securities.

      o Convertible securities, i.e., fixed income issues that give the owner
the option of a later exchange for common stock. Convertible securities entitle
the holder to receive interest payments paid on corporate debt securities or the
dividend preference on a preferred stock until such time as the convertible
security matures or is redeemed or until the holder elects to exercise the
conversion privilege. The value of convertible securities is influenced by both
the yield of nonconvertible securities of comparable issuers and by the value of
the underlying common stock. The value of a convertible security viewed without
regard to its conversion feature (i.e., strictly on


                                        3
<PAGE>   91

the basis of its yield) is sometimes referred to as its "investment value." To
the extent interest rates change, the investment value of the convertible
security typically will fluctuate. However, at the same time, the value of the
convertible security will be influenced by its "conversion value," which is the
market value of the underlying common stock that would be obtained if the
convertible security were converted. Conversion value fluctuates directly with
the price of the underlying common stock. If, because of a low price for the
common stock, the conversion value is substantially below the investment value
of the convertible security, the price of the convertible security will be
governed principally by its investment value.

      o Cash or money-market securities to produce interest income during
periods of defensive investment.

      The Investment Adviser expects that over longer periods a larger portion
of the Fund's portfolio will consist of equity securities. However, the flexible
fully managed investment approach enables the Fund to switch its emphasis to
debt and convertible securities if, in the opinion of the Investment Adviser,
prevailing market or economic conditions warrant. The Investment Adviser will
determine the emphasis among equity and debt securities, including convertible
securities, based on its evaluation as to the types of securities presently
providing the opportunity for the highest total investment return consistent
with prudent risk.

Other Investments and Risks

      In addition, the Capital Focus Fund may purchase securities that are not
registered under the Securities Act of 1933, as amended, and which therefore may
be subject to restrictions on their transfer or resale.

      The Capital Focus Fund may invest up to 25% of its total assets in
securities of foreign issuers. Investments in securities of foreign issuers
involve certain risks, including fluctuations in foreign exchange rates, future
political and economic developments, and the possible imposition of exchange
controls or other foreign governmental laws or restrictions. In addition,
foreign companies may not be subject to accounting, auditing and financial
reporting standards and requirements comparable to those of U.S. companies. The
foreign markets also have different clearance and settlement procedures, and in
certain markets there have been times when settlements have been unable to keep
pace with the volume of securities transactions, making it difficult to conduct
such transactions. Delays in settlement could result in temporary periods when
assets of the Fund are uninvested and no return is earned thereon. The inability
of the Fund to make intended security purchases due to settlement problems could
cause the Fund to miss attractive investment opportunities. Inability to dispose
of a portfolio security due to settlement problems could result either in losses
to the Fund due to subsequent declines in the value of such portfolio security
or, if the Fund has entered into a contract to sell the security, could result
in possible liability to the purchaser. To the extent such investments are
subject to withholding or other taxes or to regulations relating to repatriation
of assets, the Fund's distributable income will be reduced. The prices of
securities in different countries may be subject to different economic,
financial, political and social factors.

      The Capital Focus Fund may from time to time be invested in
non-dollar-denominated securities of foreign issuers. Changes in foreign
currency exchange rates may affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. See "Other Portfolio Strategies-Foreign Securities" in the Appendix
to this Prospectus.

      The Capital Focus Fund has established no rating criteria for the debt
securities in which it may invest, and such securities may not be rated at all
for creditworthiness. Securities rated in the medium to lower rating categories
of nationally recognized statistical rating organizations and unrated securities
of comparable quality are predominantly speculative with respect to the capacity
to pay interest and repay principal in accordance with the terms of the security
and generally involve a greater volatility of price than securities in higher
rating categories. In purchasing such securities, the Fund will rely on the
Investment Adviser's judgment, analysis and experience in evaluating the
creditworthiness of an issuer of such securities. The Investment Adviser will
take into consideration, among other things, the issuer's financial resources,
its sensitivity to economic conditions and trends, its operating history, the
quality of the issuer's management and regulatory matters. The Fund does not
intend to purchase debt


                                        4
<PAGE>   92

securities that are in default or that the Investment Adviser believes will be
in default. See "Risks of High Yield Securities" in the Appendix to this
Prospectus.

      Among the risks to which an investment in the Capital Focus Fund is
subject are interest rate risk and credit risk. Interest rate risk is the risk
that the portion of the Fund's net asset value attributable to the Fund's
fixed-income securities may fall when interest rates rise and rise when interest
rates fall. In general, fixed-income securities with longer maturities will be
subject to greater volatility resulting from interest rate fluctuations than
will fixed-income securities with shorter maturities. Credit risk is the risk
that an issuer of fixed-income securities that the Fund owns will not make
timely payments of interest or repayments of principal from the issuer. Credit
risk is generally greater in lower-rated securities.

      The Capital Focus Fund may invest in the securities of smaller or emerging
growth companies. The securities of smaller or emerging growth companies may be
subject to more abrupt or erratic market movements than larger, more established
companies or the market average in general. These companies may have limited
product lines, markets or financial resources, or they may be dependent on a
limited management group.

      The Capital Focus Fund may engage in transactions, such as currency swaps
and purchasing and selling options on currencies, for purposes of hedging
against the decline in the value of currencies in which its portfolio holdings
are denominated against the US dollar. Although such instruments will be used
with the intention of hedging against adverse currency movements, transactions
in such instruments involve the risk that anticipated currency movements will
not be accurately predicted and that the Fund's hedging strategies will be
ineffective and may cause the Fund to realize losses.

      The Capital Focus Fund may from time to time write (i.e., sell) covered
call options on its portfolio securities.

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix of this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to options and foreign exchange
transactions.

                             THE INSURANCE COMPANIES

      Shares of the Funds currently are sold to separate accounts ("Separate
Accounts") of Merrill Lynch Life Insurance Company ("MLLIC") and ML Life
Insurance Company of New York ("ML of New York"), as well as other insurance
companies not affiliated with MLLIC or ML of New York (together with MLLIC and
ML of New York, "Insurance Companies") to fund certain variable life insurance
contracts and/or variable annuities (together, "Contracts") issued by such
companies. The rights of the Insurance Companies as shareholders should be
distinguished from the rights of a Contract owner, which are set forth in the
Contract. A Contract owner has no interest in the shares of a Fund, but only in
the Contract. The Contract is described in the prospectus for each Contract.
That prospectus describes the relationship between increases or decreases in the
net asset value of shares of a Fund, and any distributions on such shares, and
the benefits provided under a Contract. The prospectus for the Contracts also
describes various fees payable to the Insurance Companies and charges to the
Separate Accounts made by the Insurance Companies with respect to the Contracts.
Since shares of the Funds will be sold only to the Insurance Companies for the
Separate Accounts, the terms "shareholder" and "shareholders" in this Prospectus
refer to the Insurance Companies. MLLIC and ML of New York are wholly owned
subsidiaries of ML&Co., as is the Investment Adviser.

                 INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS

Investment Objectives

      Each Fund of the Company has a different investment objective, which it
pursues through separate investment policies as described in the Fund's
Prospectus (of which this Appendix is a part). The differences in objectives and
policies among the Funds can be expected to affect the return of each Fund and
the degree of market and financial risk to which each Fund is subject. Each Fund
is classified as "diversified," as defined in the Investment Company Act of
1940, as amended (the "Investment Company Act" or the "Act") except for the
Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the Global
Strategy Focus Fund, the Index 500 Fund, and the Natural Resources Focus Fund,
each of which is classified as "non-diversified." The investment objectives and
classification of each Fund may not be changed without the approval of the
holders of a majority of the outstanding shares of each Fund affected.

      Fixed Income Security Ratings. No Fund other than the Developing Capital
Markets Focus Fund, the High Current Income Fund, the Capital Focus Fund and the
International Equity Focus Fund invests in fixed-income securities rated below
investment grade (i.e., securities rated Ba or below by Moody's Investors
Service, Inc. ("Moody's") or BB or below by Standard & Poor's Ratings Group
("Standard & Poor's") at the time of investment). However, securities purchased
by a Fund may subsequently be downgraded. Such securities may continue to be
held and will be sold only if, in the judgment of the Investment Adviser, it is
advantageous to do so. Securities in the lowest category of investment grade
debt securities may have speculative characteristics, which may lead to weakened
capacity to pay interest and principal during periods of adverse economic
conditions. See Annex A of this Appendix for a fuller description of corporate
bond ratings.

Non-Diversified Funds

      The Developing Capital Markets Focus, Global Bond Focus, Global Strategy
Focus, Index 500, and Natural Resources Focus Funds are classified as
non-diversified investment companies under the Investment Company Act. However,
each Fund will have to limit its investments to the extent required by the
diversification requirements applicable to regulated investment companies under
the Internal Revenue Code of 1986, as amended (the "Code" or the "Internal
Revenue Code"). To qualify as a regulated investment company, a Fund, at the
close of each fiscal quarter, may not have more than 25% of its total assets
invested in the securities (except obligations of the U.S. Government, its
agencies or instrumentalities) of any one issuer and with respect to 50% of its
assets, (i) may not have more than 5% of its total assets invested in the
securities of any one issuer and (ii) may not own more than 10% of the
outstanding voting securities of any one issuer.

Investment Restrictions

      The Company has adopted a number of restrictions and policies relating to
the investment of its assets and its activities which are fundamental policies
and may not be changed without the approval of the holders of the Company's
outstanding voting securities (including a majority of the shares of each Fund).
Investors are referred to the Statement of Additional Information for a complete
description of such restrictions and policies.

Other Portfolio Strategies

      Restricted Securities. Each of the Funds is subject to limitations on the
amount of illiquid securities it may purchase; however, each Fund may purchase
without regard to that limitation certain securities that are not registered
under the Securities Act of 1933, as amended (the "Securities Act"), including
(a) commercial paper exempt from registration under Section 4(2) of the
Securities Act, and (b) securities that can be offered and sold to "qualified
institutional buyers" under Rule 144A under the Securities Act, provided that
the Company's Board of Directors continuously determines, based on the trading
markets for the specific Rule 144A security, that it is liquid. The Board of
Directors may adopt guidelines and delegate to the Investment Adviser the daily
function of determining and monitoring liquidity of restricted securities. The
Board has determined that securities sold under Rule 144A that are freely
tradeable in their primary market offshore should be deemed liquid. The Board,
however, will retain sufficient oversight and be ultimately responsible for the
determinations.

      Since it is not possible to predict with assurance exactly how the market
for restricted securities sold and offered under Rule 144A will develop, the
Board of Directors will carefully monitor the Funds' investments in these
securities, focusing on such factors, among others, as valuation, liquidity and
availability of information. This investment practice could have the effect of
increasing the level of illiquidity in a Fund to the extent that qualified
institutional buyers become for a time uninterested in purchasing these
restricted securities.

      Foreign Securities. The Basic Value Focus, Developing Capital Markets
Focus, Special Value Focus, Global Strategy Focus, Global Bond Focus, Global
Utility Focus, High Current Income, International Equity Focus, Natural
Resources Focus, Prime Bond, Quality Equity, Global Growth Focus, Capital Focus
and Reserve Assets Funds may invest in securities of foreign issuers. The Index
500 Fund may also invest in securities of foreign issuers to the extent such
issuers are included in the Standard & Poor's 500 Composite Stock Price Index
(the "S&P Index"). Investments in foreign securities, particularly those of
non-governmental issuers, involve considerations and risks which are not
ordinarily associated with investing in domestic issuers. These considerations
and risks include changes in currency rates, currency exchange control
regulations, the possibility of expropriation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of economic, political, social or
diplomatic developments, and the difficulty of assessing economic trends in
foreign countries. Foreign legal systems may differ from the U.S. legal system,
and if it should become necessary, a Fund could encounter greater difficulties
in invoking legal processes abroad than would be the case in the United States.
Transaction costs in foreign securities may be higher. The operating expense
ratio of a Fund investing in foreign securities can be expected to be higher
than that of an investment company investing exclusively in United States
securities because the expenses of the Fund, such as custodial costs, are
higher. In addition, net investment income earned by a Fund on a foreign
security may be subject to withholding and other taxes imposed by foreign
governments which will reduce a Fund's net investment income. The Investment
Adviser will consider these and other factors before investing in foreign
securities, and will not make such investments unless, in its opinion, such
investments will meet the standards and objectives of a particular Fund. No Fund
that may invest in foreign securities, other than the Natural Resources Focus
and Global Strategy Focus Funds, will concentrate its investments in any
particular country. The Developing Capital Markets Focus, Global Bond Focus,
Global Strategy Focus, Global Utility Focus, International Equity Focus, Global
Growth Focus Fund and Natural Resources Focus Funds may from time to time be
substantially invested in non-dollar-denominated securities of foreign issuers.
For a Fund that invests in foreign securities denominated or quoted in
currencies other than the United States dollar, changes in foreign currency
exchange rates may directly affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned, and a Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign


                                       A-2
<PAGE>   96

currency rates during the period in which the Fund holds such investments.
Foreign currency exchange rates are determined by forces of supply and demand in
the foreign exchange markets. These forces are, in turn, affected by
international balance of payments and other economic and financial conditions,
government intervention, speculation and other factors. With respect to certain
countries, there may be the possibility of expropriation of assets, confiscatory
taxation, high rates of inflation, political or social instability or diplomatic
developments which could affect investment in those countries. Each Fund of the
Company other than the Developing Capital Markets Focus, Global Bond Focus,
Global Strategy Focus, Global Utility Focus, International Equity Focus, Natural
Resources Focus, Global Growth Focus, Capital Focus Fund and Quality Equity
Funds will purchase only securities issued in dollar denominations.

      The securities markets of many countries at times in the past have moved
relatively independently of one another due to different economic, financial,
political and social factors. When such lack of correlation, or negative
correlation, in movements of these securities markets occurs, it may reduce risk
for a Fund's portfolio as a whole. This negative correlation also may offset
unrealized gains a Fund has derived from movements in a particular market. To
the extent the various markets move independently, total portfolio volatility is
reduced when the various markets are combined into a single portfolio. Of
course, movements in the various securities markets may be offset by changes in
foreign currency exchange rates. Exchange rates frequently move independently of
securities markets in a particular country. As a result, gains in a particular
securities market may be affected by changes in exchange rates.

      Each of the International Equity Focus Fund and Developing Capital Markets
Focus Fund may invest a significant portion of its assets in securities of
foreign issuers in smaller capital markets, while each of the other Funds which
is permitted to invest in foreign securities may from time to time invest in
securities of such foreign issuers. Foreign investments involve risks, including
fluctuations in foreign exchange rates, future political and economic
developments, different legal systems, the existence or possible imposition of
exchange controls, or other foreign or United States governmental laws or
restrictions, that are often heightened for investments in smaller capital
markets.

      There may be less publicly available information about an issuer in a
foreign market, particularly one in a smaller capital market, than would be
available about a United States company, and it may not be subject to
accounting, auditing and financial reporting standards and requirements
comparable to those of United States companies. As a result, traditional
investment measurements, such as price/earnings ratios, as used in the United
States, may not be applicable in certain capital markets.

      Smaller capital markets, while often growing in trading volume, have
substantially less volume than United States markets, and securities in many
smaller capital markets are less liquid and their prices may be more volatile
than securities of comparable United States companies. Brokerage commissions,
custodial services, and other costs relating to investment in smaller capital
markets are generally more expensive than in the United States. Such markets
have different clearance and settlement procedures, and in certain markets there
have been times when settlements have been unable to keep pace with the volume
of securities transactions, making it difficult to conduct such transactions.
Further, satisfactory custodial services for investment securities may not be
available in some countries having smaller capital markets, which may result in
a Fund which invests in these markets incurring additional costs and delays in
transporting and custodying such securities outside such countries. Delays in
settlement could result in temporary periods when assets of such a Fund are
uninvested and no return is earned thereon. The inability of a Fund to make
intended security purchases due to settlement problems could cause the Fund to
miss attractive investment opportunities. Inability to dispose of a portfolio
security due to settlement problems could result either in losses to the Fund
due to subsequent declines in value of the portfolio security or, if the Fund
has entered into a contract to sell the security, could result in possible
liability to the purchaser. There is generally less government supervision and
regulation of exchanges, brokers and issuers in countries having smaller capital
markets than there is in the United States.

      As a result, management of a Fund that invests in foreign securities may
determine that, notwithstanding otherwise favorable investment criteria, it may
not be practicable or appropriate to invest in a particular country.


                                       A-3
<PAGE>   97

A Fund may invest in countries in which foreign investors, including management
of the Fund, have had no or limited prior experience.

      Certain of the Funds may invest in debt securities issued by foreign
governments. Investments in foreign government debt securities, particularly
those of emerging market country governments, involve special risks. Certain
emerging market countries have historically experienced, and may continue to
experience, high rates of inflation, high interest rates, exchange rate
fluctuations, large amounts of external debt, balance of payments and trade
difficulties and extreme poverty and unemployment. The issuer or governmental
authority that controls the repayment of an emerging market country's debt may
not be able or willing to repay the principal and/or interest when due in
accordance with the terms of such debt. A debtor's willingness or ability to
repay principal and interest due in a timely manner may be affected by, among
other factors, its cash flow situation, and, in the case of a government debtor,
the extent of its foreign reserves, the availability of sufficient foreign
exchange on the date a payment is due, the relative size of the debt service
burden to the economy as a whole and the political constraints to which a
government debtor may be subject. Government debtors may default on their debt
and may also be dependent on expected disbursements from foreign governments,
multilateral agencies and others abroad to reduce principal and interest
arrearages on their debt. Holders of government debt, including the Fund, may be
requested to participate in the rescheduling of such debt and to extend further
loans to government debtors.

      As a result of the foregoing, a government obligor may default on its
obligations. If such an event occurs, a Fund may have limited legal recourse
against the issuer and/or guarantor. Remedies must, in some cases, be pursued in
the courts of the defaulting party itself, and the ability of the holder of
foreign government debt securities to obtain recourse may be subject to the
political climate in the relevant country. Government obligors in developing and
emerging market countries are among the world's largest debtors to commercial
banks, other governments, international financial organizations and other
financial institutions. Some issuers of the government debt securities in which
a Fund may invest have in the past experienced substantial difficulties in
servicing their external debt obligations, which led to defaults on certain
obligations and the restructuring of certain indebtedness. Restructuring
arrangements have included, among other things, reducing and rescheduling
interest and principal payments by negotiating new or amended credit agreements.

      The Global Utility Focus Fund, International Equity Focus Fund, Developing
Capital Markets Focus Fund, Capital Focus Fund and the Global Growth Focus Fund
may invest in the securities of foreign issuers in the form of American
Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") or other
securities convertible into securities of foreign issuers. These securities may
not necessarily be denominated in the same currency as the securities into which
they may be converted. ADRs are receipts typically issued by an American bank or
trust company which evidence ownership of underlying securities issued by a
foreign corporation. EDRs are receipts issued in Europe which evidence a similar
ownership arrangement. Generally, ADRs, which are issued in registered form, are
designated for use in the United States securities markets, and EDRs, which are
issued in bearer form, are designed for use in European securities markets. The
Funds may invest in ADRs and EDRs through both sponsored and unsponsored
arrangements. In a sponsored ADR or EDR arrangement, the foreign issuer assumes
the obligation to pay some or all of the depository's transaction fees, whereas
in an unsponsored arrangement the foreign issuer assumes no obligations and the
depository's transaction fees are paid by the ADR or EDR holders. Foreign
issuers in respect of whose securities unsponsored ADRs or EDRs have been issued
are not necessarily obligated to disclose material information in the markets in
which the unsponsored ADRs or EDRs are traded and, therefore, there may not be a
correlation between such information and the market value of such securities.

      The Developing Capital Markets Focus and International Equity Focus Funds
intend to invest in securities of foreign issuers in smaller capital markets.
Some countries with smaller capital markets prohibit or impose substantial
restrictions on investments in their capital markets, particularly their equity
markets, by foreign entities such as the Fund. As illustrations, certain
countries require governmental approval prior to investments by foreign persons,
or limit the amount of investment by foreign persons in a particular company, or
limit the investment by foreign persons to only a specific class of securities
of a company which may have less advantageous terms than securities of the
company available for purchase by nationals.


                                       A-4
<PAGE>   98

      A number of countries, such as South Korea, Taiwan and Thailand, have
authorized the formation of closed-end investment companies to facilitate
indirect foreign investment in their capital markets. In accordance with the
Investment Company Act, the Developing Capital Markets Focus, Global Growth
Focus and International Equity Focus Funds each may invest up to 10% of its
total assets in securities of such closed-end investment companies. This
restriction on investments in securities of closed-end investment companies may
limit opportunities for the Fund to invest indirectly in certain smaller capital
markets. Shares of certain closed-end investment companies may at times be
acquired only at market prices representing premiums to their net asset values.
If a Fund acquires shares in closed-end investment companies, shareholders would
bear both their proportionate share of expenses in the Fund (including
management and advisory fees) and, indirectly, the expenses of such closed-end
investment companies. A Fund also may seek, at its own cost, to create its own
investment entities under the laws of certain countries.

      In some countries, banks or other financial institutions may constitute a
substantial number of the leading companies or the companies with the most
actively traded securities. Also, the Investment Company Act restricts a Fund's
investments in any equity security of an issuer which, in its most recent fiscal
year, derived more than 15% of its revenues from "securities related
activities," as defined by the rules thereunder. These provisions may also
restrict a Fund's investments in certain foreign banks and other financial
institutions.

      Rules adopted under the Investment Company Act permit the Funds to
maintain their foreign securities and cash in the custody of certain eligible
non-U.S. banks and securities depositories. Certain banks in foreign countries
may not be eligible sub-custodians for the Funds, in which event the Funds may
be precluded from purchasing securities in certain foreign countries in which
they otherwise would invest or the Funds may incur additional costs and delays
in providing transportation and custody services for such securities outside of
such countries. The Funds may encounter difficulties in effecting on a timely
basis portfolio transactions with respect to any securities of issuers held
outside their countries. Other banks that are eligible foreign sub-custodians
may be recently organized or otherwise lack extensive operating experience. In
addition, in certain countries there may be legal restrictions or limitations on
the ability of the Funds to recover assets held in custody by foreign
sub-custodians in the event of the bankruptcy of the sub-custodian.

      Lending of Portfolio Securities. Each Fund of the Company may from time to
time lend securities (but not in excess of 20% or, in the case of the Global
Growth Focus Fund 33 1/3%) of its total assets from its portfolio to brokers,
dealers and financial institutions and receive collateral in cash or securities
issued or guaranteed by the U.S. Government which, while the loan is
outstanding, will be maintained at all times in an amount equal to at least 100%
of the current market value of the loaned securities plus accrued interest. Such
cash collateral will be invested in short-term securities, the income from which
will increase the return to the Fund.

      Forward Commitments. Each of the Funds may purchase securities on a
when-issued basis, and they may purchase or sell such securities for delayed
delivery. These transactions occur when securities are purchased or sold by a
Fund with payment and delivery taking place in the future to secure what is
considered an advantageous yield and price to the Fund at the time of entering
into the transaction. The value of the security on the delivery date may be more
or less than its purchase price. A Fund entering into such transactions will
maintain a segregated account with its custodian of cash or liquid securities in
an aggregate amount equal to the amount of its commitments in connection with
such delayed delivery and purchase transactions.

      Standby Commitment Agreements. The Developing Capital Markets Focus,
Global Utility Focus, Global Growth Focus and High Current Income Funds may from
time to time enter into standby commitment agreements. Such agreements commit
the respective Fund, for a stated period of time, to purchase a stated amount of
a fixed income security which may be issued and sold to the Fund at the option
of the issuer. The price and coupon of the security is fixed at the time of the
commitment. At the time of entering into the agreement the Fund is paid a
commitment fee which is typically approximately 0.5% of the aggregate purchase
price of the security which the Fund has committed to purchase. The Fund will at
all times maintain a segregated account with its custodian of cash or liquid
securities in an amount equal to the purchase price of the securities underlying
the commitment. There can be no assurance that the securities subject to a
standby commitment will be issued, and the value of the security, if issued, on
the delivery date may be more or less than its purchase price.

<PAGE>   99

      Portfolio Strategies Involving Indexed and Inverse Securities, Options,
Futures and Foreign Exchange Transactions. Certain Funds may use derivative
instruments, including indexed and inverse securities, options and futures and
purchase and sell foreign exchange. Transactions involving such instruments
expose these Funds to certain risks. Each Fund's use of these instruments and
the associated risks are described in detail in Annex B of the Appendix attached
to this Prospectus.

Risks of High Yield Securities

      The Developing Capital Markets Focus Fund, High Current Income Fund,
International Equity Focus Fund and Capital Focus Fund may invest a substantial
portion of their assets in high yield, high risk securities or junk bonds, which
are regarded as being predominantly speculative as to the issuer's ability to
make payments of principal and interest. Investment in such securities involves
substantial risk. Issuers of junk bonds may be highly leveraged and may not have
available to them more traditional methods of financing. Therefore, the risks
associated with acquiring the securities of such issuers generally are greater
than is the case with higher-rated securities. For example, during an economic
downturn or a sustained period of rising interest rates, issuers of high yield
securities may be more likely to experience financial stress, especially if such
issuers are highly leveraged. During recessionary periods, such issuers may not
have sufficient revenues to meet their interest payment obligations. The
issuer's ability to service its debt obligations also may be adversely affected
by specific issuer developments, or the issuer's inability to meet specific
projected business forecasts, or the unavailability of additional financing. The
risk of loss due to default by the issuer is significantly greater for the
holders of junk bonds because such securities may be unsecured and may be
subordinated to other creditors of the issuer. While the high yield securities
in which the Developing Capital Markets Focus Fund, High Current Income Fund,
International Equity Focus Fund and Capital Focus Fund may invest normally do
not include securities which, at the time of investment, are in default or the
issuers of which are in bankruptcy, there can be no assurance that such events
will not occur after a Fund purchases a particular security, in which case a
Fund may experience losses and incur costs.

      In an effort to minimize the risk of issuer default or bankruptcy, the
Developing Capital Markets Focus Fund, High Current Income Fund, International
Equity Focus Fund and Capital Focus Fund each will diversify its holdings among
many issuers. However, there can be no assurance that diversification will
protect a Fund from widespread defaults brought about by a sustained economic
downturn.

      High yield securities frequently have call or redemption features that
would permit an issuer to repurchase the security from the Fund. If a call were
exercised by the issuer during a period of declining interest rates, the Fund
likely would have to replace such called security with a lower yielding
security, thus decreasing the net investment income to the Fund and dividend to
shareholders.

      High yield securities tend to be more volatile than higher-rated
fixed-income securities, so that adverse economic events may have a greater
impact on their prices and yields than on higher-rated fixed-income securities.
Zero coupon bonds and bonds which pay interest and/or principal in additional
bonds rather than in cash are especially volatile. Like higher-rated
fixed-income securities, junk bonds are generally purchased and sold through
dealers who make a market in such securities for their own accounts. However,
there are fewer dealers in this market, which may be less liquid than the market
for higher-rated fixed-income securities, even under normal economic conditions.
Also, there may be significant disparities in the prices quoted for such bonds
by various dealers. Adverse economic conditions or investor perceptions (whether
or not based on economic fundamentals) may impair the liquidity of this market,
and may cause the prices the Developing Capital Markets Focus Fund, High Current
Income Fund, International Equity Focus Fund and Capital Focus Fund receive for
their junk bonds to be reduced, or a Fund may experience difficulty in
liquidating a portion of its portfolio when necessary to meet the Fund's
liquidity needs or in response to a specific economic event such as a
deterioration in the creditworthiness of the issuer. Under such conditions,
judgement may play a greater role in valuing certain of each Fund's portfolio
securities than in the case of securities trading in a more liquid market.

      It is expected that a significant portion of the high yield securities
acquired by the Capital Focus Fund will be purchase upon issuance, which may
involve special risks because the securities so acquired are new issues. In such
instances the Capital Focus Fund may be a substantial purchaser of the issue and
therefore have the opportunity


                                       A-6
<PAGE>   100

to participate in structuring the terms of the offering. Although this may
enable the Capital Focus Fund to seek to protect itself against certain of such
risks, the considerations discussed herein would nevertheless remain applicable.

            Adverse publicity and investor perceptions, which may not be based
on fundamental analysis, also may decrease the value and liquidity of junk
bonds, particularly in a thinly traded market. Factors adversely affecting the
market value of such securities are likely to affect adversely the net asset
value of the Developing Capital Markets Focus Fund, High Current Income Fund,
Capital Focus Fund and International Equity Focus Fund. In addition, each Fund
may incur additional expenses to the extent that it is required to seek recovery
upon a default on a portfolio holding or to participate in the restructuring of
the obligation.

            Sovereign Debt. The junk bonds in which the Developing Capital
Markets Focus Fund, High Current Income Fund, Capital Focus Fund and
International Equity Focus Fund may invest include junk bonds issued by
sovereign entities. Investment in such sovereign debt involves a high degree of
risk. The governmental entity that controls the repayment of sovereign debt may
not be able or willing to repay the principal and/or interest when due in
accordance with the terms of such debt. A governmental entity's willingness or
ability to repay principal and interest due in a timely manner may be affected
by, among other factors, its cash flow situation, the extent of its foreign
reserves, the availability of sufficient foreign exchange on the date a payment
is due, the relative size of the debt service burden to the economy as a whole,
the governmental entity's policy towards the International Monetary Fund and the
political constraints to which a governmental entity may be subject.
Governmental entities may also be dependent on expected disbursements from
foreign governments, multilateral agencies and others abroad to reduce principal
and interest arrearages on their debt. The commitment on the part of these
governments, agencies and others to make such disbursements may be conditioned
on a governmental entity's implementation of economic reforms and/or economic
performance and the timely service of such debtor's obligations. Failure to
implement such reforms, achieve such levels of economic performance or repay
principal or interest when due may result in the cancellation of such third
parties' commitments to lend funds to the governmental entity, which may further
impair such debtor's ability or willingness to timely service its debts.
Consequently, governmental entities may default on their sovereign debt.

            Holders of sovereign debt, including the Developing Capital Markets
Focus Fund, High Current Income Fund, Capital Focus Fund and International
Equity Focus Fund may be requested to participate in the rescheduling of such
debt and to extend further loans to governmental entities. In the event of a
default by a governmental entity, there may be few or no effective legal
remedies available to a Fund and there can be no assurance a Fund will be able
to collect on defaulted sovereign debt in whole or in part.

Insurance Law Restrictions

      In order for shares of the Company's Funds to remain eligible investments
for the Separate Accounts, it may be necessary, from time to time, for a Fund to
limit its investments in certain types of securities in accordance with the
insurance laws or regulations of the various states in which the Contracts are
sold.

      The New York insurance law requires that investments of each Fund be made
with the degree of care of an "ordinarily prudent person." The Investment
Adviser believes that compliance with this standard will not have any negative
impact on the performance of any of the Funds.

Other Considerations

      The Investment Adviser will use its best efforts to assure that each Fund
of the Company complies with certain investment limitations of the Internal
Revenue Service to assure favorable income tax treatment for the Contracts. It
is not expected that such investment limitations will materially affect the
ability of any Fund to achieve its investment objective.

<PAGE>   101

                                    DIRECTORS

      The Investment Adviser has entered into a sub-advisory agreement (the
"Sub-Advisory Agreement") with MLAM U.K., an indirect wholly owned subsidiary of
ML & Co., and an affiliate of the Investment Adviser, pursuant to which the
Investment Adviser pays MLAM U.K. a fee for providing investment advisory
services to the Investment Adviser with respect to the Funds in an amount to be
determined from time to time by the Investment Adviser and MLAM U.K. but in no
event in excess of the amount that the Investment Adviser actually receives for
providing services to the Funds pursuant to the Investment Advisory Agreement.

      The Investment Adviser and Merrill Lynch Life Agency, Inc. ("MLLA") have
entered into agreements which limit the operating expenses, exclusive of any
distribution fees imposed on shares of Class B Common Stock, paid by each Fund
in a given year to 1.25% of its average daily net assets (the "Reimbursement
Agreements"). The Reimbursement Agreement provides that any such expenses in
excess of 1.25% of average daily net assets will be reimbursed to the Fund by
the Investment Adviser which, in turn, will be reimbursed by MLLA.

      The Investment Adviser has entered into administrative services agreements
with certain Insurance Companies, including MLLIC and ML of New York, pursuant
to which the Investment Adviser compensates such companies for administrative
responsibilities relating to the Company which are performed by such Insurance
Companies.

Code of Ethics

      The Board of Directors of the Company has adopted a Code of Ethics under
Rule 17j-1 of the Act which incorporates the Code of Ethics of the Investment
Adviser (together, the "Codes"). The Codes significantly restrict


                                       A-9
<PAGE>   103

the personal investing activities of all employees of the Investment Adviser
and, as described below, impose additional, more onerous, restrictions on fund
investment personnel.

            The Codes require that all employees of the Investment Adviser
preclear any personal securities investment (with limited exceptions, such as
government securities). The preclearance requirement and associated procedures
are designed to identify any substantive prohibition or limitation applicable to
the proposed investment. The substantive restrictions applicable to all
employees of the Investment Adviser include a ban on acquiring any securities in
a "hot" initial public offering and a prohibition from profiting on short-term
trading in securities. In addition, no employee may purchase or sell any
security which at the time is being purchased or sold (as the case may be), or
to the knowledge of the employee is being considered for purchase or sale, by
any fund advised by the Investment Adviser. Furthermore, the Codes provide for
trading "blackout periods" which prohibit trading by investment personnel of the
Company within periods of trading by the Company in the same (or equivalent)
security (15 or 30 days depending upon the transaction).

Subject to policy established by the Board of Directors of the Company, the
Investment Adviser is primarily responsible for the Company's portfolio
decisions and the placing of the Company's portfolio transactions. In placing
orders, it is the policy of each Fund to obtain the most favorable net results,
taking into account various factors, including price, dealer spread or
commission, if any, size of the transactions and difficulty of execution. While
the Investment Adviser generally seeks reasonably competitive spreads or
commissions, the Company will not necessarily be paying the lowest spread or
commission available.

      Under the Investment Company Act of 1940, persons affiliated with the
Company are prohibited from dealing with the Company as a principal in the
purchase and sale of the Company's portfolio securities unless an exemptive
order allowing such transactions is obtained from the Securities and Exchange
Commission. Affiliated persons of the Company may serve as its broker in
over-the-counter transactions conducted on an agency basis.


                                      A-11
<PAGE>   105

The Securities and Exchange Commission has issued an order permitting the
Company to conduct certain principal transactions with respect to the Domestic
Money Market and Reserve Assets Funds with Merrill Lynch Government Securities
Inc. and Merrill Lynch Money Markets Inc. in U.S. Government and Government
agency securities, and certain other money market securities, subject to certain
terms and conditions. During the fiscal year ended December 31, 1997, the
Company engaged in 15 transactions pursuant to such order involving
approximately $49.2 million of securities. For the year ended December 31, 1997,
the Company paid brokerage commissions of $8,344,021, of which $302,843 was paid
to Merrill Lynch.

                               PURCHASE OF SHARES

      The Company continuously offers shares in each of its Funds to the
Insurance Companies at prices equal to the respective per share net asset value
of the Funds. Merrill Lynch Funds Distributor, Inc., a wholly owned subsidiary
of the Investment Adviser, acts as the distributor of the shares. Net Asset
Value is determined in the manner set forth below under "Additional
Information -- Determination of Net Asset Value."

      The Company and the Distributor reserve the right to suspend the sale of
shares of each Fund in response to conditions in the securities markets or
otherwise.

                              REDEMPTION OF SHARES

      The Company is required to redeem all full and fractional shares of the
Funds for cash. The redemption price is the net asset value per share next
determined after the initial receipt of proper notice of redemption.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES

      It is the Company's intention to distribute substantially all of the net
investment income, if any, of each Fund. For dividend purposes, net investment
income of each Fund, other than the Company's Domestic Money Market and Reserve
Assets Funds, will consist of all payments of dividends or interest received by
such Fund less the estimated expenses of such Fund (including fees payable to
the Investment Adviser). Net investment income of the Domestic Money Market and
Reserve Assets Funds (from the time of the immediate preceding determination
thereof) consists of (i) interest accrued and/or discount earned (including both
original issue and market discount), (ii) plus or minus all realized and
unrealized gains (other than realized long-term capital gains) and losses on its
portfolio securities, (iii) less the estimated expenses of the respective Fund
(including the fees payable to the Investment Adviser) applicable to that
dividend period. Dividends on the Domestic Money Market and Reserve Assets Funds
are declared daily and reinvested monthly in additional full and fractional
shares of such Fund. Dividends from net investment income of the Global Bond
Focus, Government Bond, High Current Income and Prime Bond Funds are declared
and reinvested monthly in additional full and fractional shares of the
respective Funds at net asset value. Dividends from net investment income of the
Global Utility Focus Fund are declared and reinvested quarterly in additional
full and fractional shares of the Fund. Dividends from net investment income of
the American Balanced, Basic Value Focus, Capital Focus, Developing Capital
Markets Focus, Special Value Focus, Global Strategy Focus, Global Growth Focus,
Index 500, International Equity Focus, National Resources Focus and Quality
Equity Funds are declared and reinvested at least annually in additional full
and fractional shares of the respective Funds.

      All net realized long-term or short-term capital gains of the Company, if
any, other than short-term capital gains of the Domestic Money Market and
Reserve Assets Funds, are declared and distributed annually after the close of
the Company's fiscal year to the shareholders of the Fund or Funds to which such
gains are attributable. Short- term capital gains are taxable as ordinary
income.

Tax Treatment of the Company

      Each Fund intends to continue to qualify as a regulated investment company
under certain provisions of the Internal Revenue Code. Under such provisions, a
Fund will not be subject to federal income tax on such part of its net ordinary
income and net realized capital gains which it distributes to shareholders. One
of the requirements


                                      A-12
<PAGE>   106

to qualify for treatment as a regulated investment company under the Code is
that a Fund, among other things, derive less than 30% of its gross income in
each taxable year from gains (without deduction of losses) from the sale or
other disposition of stocks, securities and certain options, futures or forward
contracts held for less than three months. This requirement may limit the
ability of certain Funds to dispose of certain securities at times when
management of the Company might otherwise deem such disposition appropriate or
desirable.

      If a Fund earns original issue discount income in a taxable year which is
not represented by correlative cash income, or if a Fund receives property
rather than cash in payment of interest, shareholders will be allocated income
greater than the amount of cash distributed to them. In addition, the Fund may
have to dispose of securities and use the proceeds thereof to make distributions
in amounts necessary to satisfy its distribution requirements under the Code.

Tax Treatment of Insurance Companies as Shareholders

      Dividends paid by the Company from its ordinary income and distributions
of the Company's net realized capital gains are includable in the respective
Insurance Company's gross income. Distributions of the Company's net realized
long-term capital gains retain their character as long-term capital gains in the
hands of the Insurance Companies if certain requirements are met. The tax
treatment of such dividends and distributions depends on the respective
Insurance Company's tax status. To the extent that income of the Company
represents dividends on common or preferred stock, rather than interest income,
its distributions to the Insurance Companies will be eligible for the present
70% dividends received deduction applicable in the case of a life insurance
company as provided in the Code. See the Prospectus for the Contracts for a
description of the respective Insurance Company's tax status and the charges
which may be made to cover any taxes attributable to the Separate Account. Not
later than 60 days after the end of each calendar year, the Company will send to
the Insurance Companies a written notice required by the Code designating the
amount and character of any distributions made during such year.

                                PERFORMANCE DATA

      From time to time the average annual total return and yield of one or more
of the Company's Funds for various specified time periods may be included in
advertisements or information furnished by the Insurance Companies to present or
prospective Contract owners. Average annual total return and yield are computed
in accordance with formulas specified by the Securities and Exchange Commission.
In connection with its reorganization on December 6, 1996, the Global Bond Focus
Fund (i) acquired substantially all of the assets and assumed substantially all
the liabilities of the International Bond Fund, a separate Fund of the Company,
(ii) implemented a change in its investment objective and policies from seeking
high current income from a global portfolio of fixed income securities,
including non-investment grade securities, to seeking a high total investment
return by investing in a global portfolio of investment grade fixed income
securities and (iii) changed its name from the World Income Focus Fund to its
current name. For the period from the commencement of the World Income Focus
Fund's operations through its reorganization on December 6, 1996, the portfolio
of the Fund included debt securities rated below investment grade (i.e., junk
bonds). On December 6, 1996, the Government Bond Fund (i) implemented a change
in its investment objective so that the Fund may invest in any debt securities
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
without regard to remaining maturity and (ii) changed its name from the
Intermediate Government Bond Fund to its current name. For the period from the
commencement of the Fund's operations through December 6, 1996, the portfolio of
the Intermediate Government Bond Fund consisted primarily of intermediate-term
debt securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities with a maximum maturity not to exceed fifteen years. As a
result of the foregoing changes in the investment objective of each of the
Global Bond Focus Fund and the Government Bond Fund, the performance information
set forth herein and in the Statement of Additional Information for the fiscal
year ended December 31, 1996 may not be indicative of such Fund's future
performance.

      Average annual total return quotations for the specified periods will be
computed by finding the average annual compounded rates of return (based on net
investment income and any realized and unrealized capital gains or losses on
portfolio investments over such periods) that would equate the initial amount
invested to the redeemable


                                      A-13
<PAGE>   107

value of such investment at the end of each period. Average annual total return
will be computed assuming all dividends and distributions are reinvested and
taking into account all applicable recurring and nonrecurring expenses.

      Yield quotations will be computed based on a 30-day period by dividing (a)
the net income based on the yield to maturity of each security earned during the
period by (b) the average daily number of shares outstanding during the period
that were entitled to receive dividends multiplied by the offering price per
share on the last day of the period. The yield for the 30-day period ending
December 31, 1997 was 6.05% for the Prime Bond Fund, 8.73% for the High Current
Income Fund, 6.11% for the Global Bond Focus Fund and 5.52% for the Government
Bond Fund.

      Total return and yield figures are based on the Fund's historical
performance and are not intended to indicate future performance. The Fund's
total return and yield will vary depending on market conditions, the securities
comprising the Fund's portfolio, the Fund's operating expenses and the amount of
realized and unrealized net capital gains or losses during the period. The value
of an investment in the Fund will fluctuate and an investor's shares, when
redeemed, may be worth more or less than their original cost. The yield and
total return quotations may be of limited use for comparative purposes because
they do not reflect charges imposed at the Separate Account level which, if
included, would decrease the yield.

      On occasion, one or more of the Company's Funds may compare its
performance to that of the S&P 500 Index, the Value Line Composite Index, the
Dow Jones Industrial Average, or performance data published by Lipper Analytical
Services, Inc., or Variable Annuity Research Data Service or contained in
publications such as Morningstar Publications, Inc., Chase Investment
Performance Digest, Money Magazine, U.S. News & World Report, Business Week,
Financial Services Weekly, Kiplinger Personal Finances, CDA Investment
Technology, Inc., Forbes Magazine, Fortune Magazine, Wall Street Journal, USA
Today, Barrons, Strategic Insight, Donaghues, Investors Business Daily and
Ibbotson Associates. As with other performance data, performance comparisons
should not be considered indicative of the Fund's relative performance for any
future period.

                             ADDITIONAL INFORMATION

Determination of Net Asset Value

      The net asset value of each class of shares of each Fund is determined
once daily by the Investment Adviser immediately after the declaration of
dividends, if any, and is determined as of fifteen minutes following the close
of trading (generally 4:00 p.m., New York time) on each day the New York Stock
Exchange ("NYSE") is open for business. The NYSE is open on business days other
than national holidays and Good Friday. The net asset value per share of each
class of shares of a Fund other than the Domestic Money Market and Reserve
Assets Funds is computed by dividing the sum of the value of the securities plus
any cash or other assets (including interest and dividends accrued) held by such
Fund and attributable to such class minus all liabilities (including accrued
expenses) attributable to such class by the total number of shares of such class
outstanding of that Fund at such time, rounded to the nearest cent. Expenses,
including the investment advisory fees payable to the Investment Adviser, are
accrued daily. Since the net investment income of the Domestic Money Market and
Reserve Assets Funds (including realized and unrealized gains and losses on
their portfolio securities) are declared as a dividend each time the net income
of the Funds are determined (see "Dividends, Distributions and Taxes"), the net
asset value per share of the Funds normally remains at $1.00 per share
immediately after each such determination and dividend declaration.

      Except with respect to securities held by the Domestic Money Market and
Reserve Assets Funds having a remaining maturity of 60 days or less, securities
held by each Fund will be valued as follows: Portfolio securities that are
traded on stock exchanges are valued at the last sale price (regular way) as of
the close of business on the day the securities are being valued, or, lacking
any sales, at the last available bid price for long positions and at the last
available ask price for short positions. Long positions in securities traded in
the over-the-counter ("OTC") market are valued at the last available bid price
in the OTC market prior to the time of valuation, provided however that the
Index 500 Fund will value its portfolio holdings which trade on the NASDAQ
national market system at the last sale price prior to the time of valuation.
Short positions in securities traded in the OTC market are valued at the last
available ask price in the OTC market prior to the time of valuation. Portfolio
securities that are traded


                                      A-14
<PAGE>   108

both in the OTC market and on a stock exchange are valued according to the
broadest and most representative market, and it is expected that for debt
securities this ordinarily will be the OTC market. When a Fund writes an option,
the amount of the premium received is recorded on the books as an asset and an
equivalent liability. The amount of the liability is subsequently valued to
reflect the current market value of the option written, based upon the last sale
price in the case of exchange-traded options or, in the case of options traded
in the OTC market, the last asked price. Options purchased are valued at their
last sale price in the case of exchange-traded options or, in the case of
options traded in the OTC market, the last bid price. Futures contracts are
valued at settlement price at the close of the applicable exchange. Securities
and assets for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board of
Directors of the Company. Any assets or liabilities initially expressed in terms
of non-U.S. dollar currencies are translated into U.S. dollars at the prevailing
market rates as quoted by one or more banks or dealers on the day of valuation.
Securities held by the Domestic Money Market and Reserve Assets Funds with a
remaining maturity of 60 days or less are valued on an amortized cost basis,
unless particular circumstances dictate otherwise.

      The Company has used pricing services, including Merrill Lynch Securities
Pricing(TM) Service ("MLSPS"), to value securities held by the High Current
Income and Prime Bond Funds and to value bonds held by other of the Company's
Funds. The Board of Directors of the Company has examined the methods used by
the pricing services in estimating the value of securities held by the Funds and
believes that such methods will reasonably and fairly approximate the price at
which those securities may be sold and result in a good faith determination of
the fair value of such securities; however, there is no assurance that
securities can be sold at the prices at which they are valued. During the fiscal
year ended December 31, 1997, American Balanced Fund, Global Strategy Focus
Fund, Global Utility Focus Fund, High Current Income Fund, Government Bond Fund,
Prime Bond Fund and Global Bond Focus Fund paid MLSPS $248, $239, $43, $7,008,
$1,676, $8,877 and $116, respectively.

on a class whose shareholders have not approved such matter. Each issued and
outstanding share of a class is entitled to one vote and to participate equally
in dividends and distributions declared with respect to such class and in net
assets of such class upon liquidation or dissolution remaining after
satisfaction of outstanding liabilities. The shares of each class, when issued,
will be fully paid and nonassessable, have no preference, preemptive,
conversion, exchange or similar rights, and will be freely transferable. Holders
of shares of any class are entitled to redeem their shares as set forth under
"Redemption of Shares." Shares do not have cumulative voting rights and the
holders of more than 50% of the shares of the Company voting for the election of
directors can elect all of the directors of the Company if they choose to do so
and in such event the holders of the remaining shares would not be able to elect
any directors. The Company does not intend to hold meetings of shareholders
unless under the Investment Company Act of 1940 shareholders are required to act
on any of the following matters: (i) election of directors; (ii) approval of an
investment advisory agreement; (iii) approval of a distribution agreement; and
(iv) ratification of the selection of independent accountants.

                                     ANNEX A

         DESCRIPTION OF TEMPORARY INVESTMENTS AND CORPORATE BOND RATINGS

U.S. Government Securities

      The Domestic Money Market Fund, Reserve Assets Fund, Capital Focus Fund
and the Government Bond Fund (and, for temporary or defensive purposes, each
other Fund) may invest in the various types of marketable securities issued by
or guaranteed as to principal and interest by the U.S. Government and supported
by the full faith and credit of the U.S. Treasury. U.S. Treasury obligations
differ mainly in the length of their maturity. Treasury bills, the most
frequently issued marketable government security, have a maturity of up to one
year and are issued on a discount basis.

Government Agency Securities

      The Domestic Money Market Fund, Reserve Assets Fund, Capital Focus Fund
and the Government Bond Fund (and, for temporary or defensive purposes, each
other Fund) may invest in government agency securities, which are debt
securities issued by government sponsored enterprises, federal agencies and
international institutions. Such securities are not direct obligations of the
Treasury but involve government sponsorship or guarantees by government agencies
or enterprises. The Funds may invest in all types of government agency
securities currently outstanding or to be issued in the future.

Depositary Institutions Money Instruments

      The Domestic Money Market Fund, Reserve Assets Fund and Capital Focus Fund
(and, for temporary or defensive purposes, each other Fund) may invest in
depositary institutions money instruments, such as certificates of deposit,
including variable rate certificates of deposit, bankers' acceptances, time
deposits and bank notes. Certificates of deposit are generally short-term,
interest-bearing negotiable certificates issued by commercial banks, savings
banks or savings and loan associations against funds deposited in the issuing
institution. Variable rate certificates of deposit are certificates of deposit
on which the interest rate is periodically adjusted prior to their stated
maturity, usually at 30, 90 or 180 day intervals ("coupon dates"), based upon a
specified market rate. As a result of these adjustments, the interest rate on
these obligations may be increased or decreased periodically. Often, dealers
selling variable rate certificates of deposit to the Funds agree to repurchase
such instruments, at the Funds' option, at par on the coupon dates. The dealers'
obligations to repurchase these instruments are subject to conditions imposed by
the various dealers; such conditions typically are the continued credit standing
of the issuer and the existence of reasonably orderly market conditions. The
Funds are also able to sell variable rate certificates of deposit in the
secondary market. Variable rate certificates of deposit normally carry a higher
interest rate than comparable fixed rate certificates of deposit because
variable rate certificates of deposit generally have a longer stated maturity
than comparable fixed rate certificates of deposit. As a matter of policy, the
Domestic Money Market Fund will invest only in these types of instruments issued
by U.S. issuers.

      A bankers' acceptance is a time draft drawn on a commercial bank by a
borrower usually in connection with an international commercial transaction (to
finance the import, export, transfer or storage of goods). The borrower is
liable for payment as well as the bank, which unconditionally guarantees to pay
the draft at its face amount on the maturity date. Most acceptances have
maturities of six months or less and are traded in secondary markets prior to
maturity.

      The Reserve Assets Fund and Capital Focus Fund (and, for temporary or
defensive purposes, the Natural Resources Focus Fund, Global Strategy Focus
Fund, Global Bond Focus Fund, Global Utility Focus Fund, International Equity
Focus Fund, Developing Capital Markets Focus Fund and the Quality Equity Fund)
may invest in certificates of deposit and bankers' acceptances issued by foreign
branches or subsidiaries of U.S. banks ("Eurodollar" obligations) or U.S.
branches or subsidiaries of foreign banks ("Yankeedollar" obligations). The Fund
may invest only in Eurodollar obligations which by their terms are general
obligations of the U.S. parent bank and meet the other criteria discussed below.
Yankeedollar obligations in which the Fund may invest must be issued


                                    Annex A-1
<PAGE>   112

by U.S. branches or subsidiaries of foreign banks which are subject to state or
federal banking regulations in the U.S. and by their terms must be general
obligations of the foreign parent. In addition, the Fund will limit its
investments in Yankeedollar obligations to obligations issued by banking
institutions with more than $1 billion in assets.

      The Reserve Assets Fund and Capital Focus Fund (and, for temporary or
defensive purposes, the Natural Resources Focus Fund, Global Strategy Focus
Fund, Global Bond Focus Fund, Global Utility Focus Fund, International Equity
Focus Fund, Developing Capital Markets Focus Fund and the Quality Equity Fund)
may also invest in U.S. dollar-denominated obligations of foreign depository
institutions and their foreign branches and subsidiaries, such as certificates
of deposit, bankers' acceptances, time deposits and deposit notes. The
obligations of such foreign branches and subsidiaries may be the general
obligation of the parent bank or may be limited to the issuing branch or
subsidiary by the terms of the specific obligation or by government regulation.
Such investments will only be made if determined to be of comparable quality to
other investments permissible for the Reserve Assets Fund. The Reserve Assets
Fund will not invest more than 25% of its total assets (taken at market value at
the time of each investment) in these obligations.

      Except as otherwise provided above with respect to investment in
Yankeedollar and other foreign bank obligations no Fund may invest in any bank
money instrument issued by a commercial bank or a savings and loan association
unless the bank or association is organized and operating in the United States,
has total assets of at least $1 billion and its deposits are insured by the
Federal Deposit Insurance Corporation (the "FDIC"); provided that this
limitation shall not prohibit the investment of up to 10% of the total assets of
a Fund (taken at market value at the time of each investment) in certificates of
deposit issued by banks and savings and loan associations with assets of less
than $1 billion if the principal amount of each such certificate of deposit is
fully insured by the FDIC.

Short-Term Debt Instruments

      The Domestic Money Market Fund, Reserve Assets Fund and Capital Focus Fund
(and, for temporary or defensive purposes, each other Fund) may invest in
commercial paper (including variable amount master demand notes and insurance
company funding agreements), which refers to short-term, unsecured promissory
notes issued by corporations, partnerships, trusts and other entities to finance
short-term credit needs and by trusts issuing asset- backed commercial paper.
Commercial paper is usually sold on a discount basis and has a maturity at the
time of issuance not exceeding nine months. Variable amount master demand notes
are demand obligations that permit the investment of fluctuating amounts at
varying market rates of interest pursuant to arrangements between the issuer and
a commercial bank acting as agent for the payees of such notes, whereby both
parties have the right to vary the amount of the outstanding indebtedness on the
notes. Because variable amount master notes are direct lending arrangements
between the lender and borrower, it is not generally contemplated that such
instruments will be traded and there is no secondary market for the notes.
Typically, agreements relating to such notes provide that the lender may not
sell or otherwise transfer the note without the borrower's consent. Such notes
provide that the interest rate on the amount outstanding is adjusted
periodically, typically on a daily basis, in accordance with a stated short-term
interest rate benchmark. Because the interest rate of a variable amount master
note is adjusted no less often than every 60 days and since repayment of the
note may be demanded at any time, the Investment Adviser values such a note in
accordance with the amortized cost basis described under "Determination of Net
Asset Value" in the Statement of Additional Information.

      The Domestic Money Market Fund and Reserve Assets Fund may also invest in
nonconvertible debt securities issued by entities or asset-backed nonconvertible
debt securities issued by trusts (e.g., bonds and debentures) with no more than
397 days (13 months) remaining to maturity at date of settlement. Short-term
debt securities with a remaining maturity of less than one year tend to become
extremely liquid and are traded as money market securities. For a discussion of
the ratings requirements of the Funds' portfolio securities, see "Portfolio
Restrictions" in the Prospectuses to the Domestic Money Market Fund and Reserve
Assets Fund.

      The Reserve Assets Fund and the Capital Focus Fund (and, for temporary or
defensive purposes, the Natural Resources Focus Fund, Global Strategy Focus
Fund, Global Bond Focus Fund, Global Utility Focus Fund, International Equity
Focus Fund and Developing Capital Markets Focus Fund) may also invest in U.S.
dollar-


                                    Annex A-2
<PAGE>   113

denominated commercial paper and other short-term obligations issued by foreign
entities. Such investments are subject to quality standards similar to those
applicable to investments in comparable obligations of domestic issuers.
Investments in foreign entities in general involve the same risks as those
described in the Statement of Additional Information in connection with
investments in Eurodollar, Yankeedollar and foreign bank obligations.

Repurchase Agreements

      Repurchase Agreements; Purchase and Sale Contracts. Each Fund may invest
in securities pursuant to repurchase agreements or purchase and sale contracts.
Under a repurchase agreement, the seller agrees, upon entering into the contract
with the Fund, to repurchase a security (typically a security issued or
guaranteed by the U.S. government) at a mutually agreed upon time and price,
thereby determining the yield during the term of the agreement. This results in
a fixed yield for the Fund insulated from fluctuations in the market value of
the underlying security during such period, although, to the extent the
repurchase agreement is not denominated in U.S. dollars, the Fund's return may
be affected by currency fluctuations. Repurchase agreements may be entered into
only with a member bank of the Federal Reserve System, a primary dealer in U.S.
government securities or an affiliate thereof. A purchase and sale contract is
similar to a repurchase agreement, but purchase and sale contracts, unlike
repurchase agreements, allocate interest on the underlying security to the
purchaser during the term of the agreement and generally do not require the
seller to provide additional securities in the event of a decline in the market
value of the purchased security during the term of the agreement. If the seller
were to default on its obligation to repurchase a security under a repurchase
agreement or purchase and sale contract and the market value of the underlying
security at such time was less than the Fund had paid to the seller, the Fund
would realize a loss. Repurchase agreements maturing in more than seven days
will be considered "illiquid securities." The Domestic Money Markets and Reserve
Assets Funds will not enter into repurchase agreements maturing in more than 30
days.

      Reverse Repurchase Agreements. The Domestic Money Market and Reserve
Assets Funds may enter into reverse repurchase agreements, which involve the
sale of money market securities held by the Funds, with an agreement to
repurchase the securities at an agreed upon price, date, and interest payment.
The Funds will use the proceeds of the reverse repurchase agreements to purchase
other money market securities either maturing, or under an agreement to resell,
at a date simultaneous with or prior to the expiration of the reverse repurchase
agreement. The Funds will utilize reverse repurchase agreements when the
interest income to be earned from the investment of the proceeds of the
transaction is greater than the interest expense of the reverse repurchase
transaction. A separate account of the applicable Fund will be established with
the Custodian consisting of cash or liquid securities having a market value at
all times at least equal in value to the proceeds received on any sale subject
to repurchase plus accrued interest.

Description of Corporate Bond Ratings

      Moody's Investors Service, Inc. ("Moody's"):

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

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

            A -- Bonds which are rated A possess many favorable investment
      attributes and are to be considered as upper medium-grade obligations.
      Factors giving security to principal and interest are considered adequate
      but elements may be present which suggest a susceptibility to impairment
      sometime in the future.


                                    Annex A-3
<PAGE>   114

            Baa -- Bonds which are rated Baa are considered medium-grade
      obligations, i.e., they are neither highly protected nor poorly secured.
      Interest payments and principal security appear adequate for the present
      but certain protective elements may be lacking or may be
      characteristically unreliable over any length of time. Such bonds lack
      outstanding investment characteristics and in fact have speculative
      characteristics as well.

            Ba -- Bonds which are rated Ba are judged to have speculative
      elements; their future cannot be considered as well assured. Often the
      protection of interest and principal payments may be very moderate and
      thereby not well safeguarded both during good and bad times over the
      future. Uncertainty of position characterizes bonds in this class.

            B -- Bonds which are rated B generally lack characteristics of a
      desirable investment. Assurance of interest and principal payments or of
      maintenance of other terms of the contract over any period of time may be
      small.

            Caa -- Bonds which are rated Caa are of poor standing. Such issues
      may be in default or there may be present elements of danger with respect
      to principal or interest.

            Ca -- Bonds which are rated Ca represent obligations which are
      speculative in a high degree. Such issues are often in default or have
      other market shortcomings.

            C -- Bonds which are rated C are the lowest rated class of bonds and
      issues so rated can be regarded as having extremely poor prospects of ever
      attaining any real investment standing.

      Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic
rating classification from Aa through B in 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.

      Standard & Poor's Ratings Services ("Standard & Poor's"):

            AAA -- This is the highest rating assigned by Standard & Poor's to a
      debt obligation and indicates an extremely strong capacity to pay
      principal and interest.

            AA -- Bonds rated AA also qualify as high-quality debt obligations.
      Capacity to pay principal and interest is very strong, and in the majority
      of instances they differ from AAA issues only in small degree.

            A -- Bonds rated A have a strong capacity to pay principal and
      interest, although they are somewhat more susceptible to the adverse
      effects of changes in circumstances and economic conditions.

            BBB -- Bonds rated BBB are regarded as having an adequate capacity
      to pay principal and interest. Whereas they normally exhibit adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      principal and interest for bonds in this category than for bonds in the A
      category.

            BB -- B -- CCC -- CC -- Bonds rated BB, B, CCC, and CC are regarded,
      on balance, as predominantly speculative with respect to the issuer's
      capacity to pay interest and repay principal in accordance with the terms
      of the obligations. BB indicates the lowest degree of speculation and CC
      the highest degree of speculation. While such bonds will likely have some
      quality and protective characteristics, these are outweighed by large
      uncertainties or major risk exposures to adverse conditions.

            NR -- Not rated by the indicated rating agency.


                                    Annex A-4
<PAGE>   115

            Plus (+) or Minus (-): The ratings from "AA" to "B" may be modified
      by the addition of a plus or minus sign to show relative standing within
      the major rating categories.

                                     ANNEX B

                      DESCRIPTION OF DERIVATIVE INSTRUMENTS

      Certain Funds of the Company are authorized to use derivative instruments,
including indexed and inverse securities, options, and futures, and to purchase
and sell foreign exchange, as described below. Such instruments are referred to
collectively herein as "Strategic Instruments."

Indexed and Inverse Securities

      The Domestic Money Market Fund, the Global Bond Focus Fund, the Global
Strategy Focus Fund, the Global Utility Focus Fund, the Government Bond Fund,
the Index 500 Fund, the International Equity Focus Fund, the Natural Resources
Focus Fund, the Prime Bond Fund, the Developing Capital Markets Focus Fund, the
Global Growth Focus Fund, and the Reserve Assets Fund may invest in securities
the potential return of which is based on the change in particular measurements
of value or rate (an "index"). As an illustration, a Fund may invest in a debt
security that pays interest and returns principal based on the change in the
value of an interest rate index (such as the prime rate or federal funds rate),
a securities index (such as the Standard & Poor's 500 Composite Index (the "S&P
500") or a more narrowly-focused index such as the AMEX Oil & Gas Index) or a
basket of securities, or based on the relative changes of two indices. In
addition, the Developing Capital Markets Focus Fund, the Global Strategy Focus
Fund, the International Equity Focus Fund and the Natural Resources Focus Fund
may invest in securities the potential return of which is based inversely on the
change in an index. For example, these Funds may invest in securities that pay a
higher rate of interest when a particular index decreases and pay a lower rate
of interest (or do not fully return principal) when the value of the index
increases. If the Fund invests in such securities, it may be subject to reduced
or eliminated interest payments or loss of principal in the event of an adverse
movement in the relevant index or indices.

      Certain indexed and inverse securities may have the effect of providing
investment leverage because the rate of interest or amount of principal payable
increases or decreases at a rate that is a multiple of the changes in the
relevant index. As a consequence, the market value of such securities may be
substantially more volatile than the market values of other debt securities. The
Company believes that indexed and inverse securities may provide portfolio
management flexibility that permits Funds to seek enhanced returns, hedge other
portfolio positions or vary the degree of portfolio leverage with greater
efficiency than would otherwise be possible under certain market conditions.

Options on Securities and Securities Indices

      Purchasing Options. The Developing Capital Markets Focus Fund, the Global
Bond Focus Fund, the Global Strategy Focus Fund, the Global Utility Focus Fund,
the Index 500 Fund, the International Equity Focus Fund, the Global Growth Focus
Fund, and the Natural Resources Focus Fund are each authorized to purchase put
options on securities held in its portfolio or securities indices the
performance of which is substantially correlated with securities held in its
portfolio. When a Fund purchases a put option, in consideration for an upfront
payment (the "option premium") the Fund acquires a right to sell to another
party specified securities owned by the Fund at a specified price (the "exercise
price") on or before a specified date (the "expiration date"), in the case of an
option on securities, or to receive from another party a payment based on the
amount a specified securities index declines below a specified level on or
before the expiration date, in the case of an option on a securities index. The
purchase of a put option limits the Fund's risk of loss in the event of a
decline in the market value of the portfolio holdings underlying the put option
prior to the option's expiration date. If the market value of the portfolio
holdings associated with the put option increases rather than decreases,
however, the Fund will lose the option premium and will consequently realize a
lower return on the portfolio holdings than would have been realized without the
purchase of the put.

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Index 500 Fund, the International Equity Focus
Fund, the Global Growth Focus Fund and the Natural Resources Focus Fund are each
authorized to purchase call options on securities it intends to purchase or
securities


                                    Annex B-1
<PAGE>   117

indices the performance of which are substantially correlated with the
performance of the types of securities it intends to purchase. When a Fund
purchases a call option, in consideration for the option premium the Fund
acquires a right to purchase from another party specified securities at the
exercise price on or before the expiration date, in the case of an option on
securities, or to receive from another party a payment based on the amount a
specified securities index increases beyond a specified level on or before the
expiration date, in the case of an option on a securities index. The purchase of
a call option may protect the Fund from having to pay more for a security as a
consequence of increases in the market value for the security during a period
when the Fund is contemplating its purchase, in the case of an option on a
security, or attempting to identify specific securities in which to invest in a
market the Fund believes to be attractive, in the case of an option on an index
(an "anticipatory hedge"). In the event the Fund determines not to purchase a
security underlying a call option, however, the Fund may lose the entire option
premium.

      Each Fund is also authorized to purchase put or call options in connection
with closing out put or call options it has previously sold.

      Writing Options. The American Balanced Fund, the Basic Value Focus Fund,
the Developing Capital Markets Focus Fund, the Special Value Focus Fund, the
Global Bond Focus Fund, the Global Strategy Focus Fund, the Global Utility Focus
Fund, the Index 500 Fund, the International Equity Focus Fund, the Natural
Resources Focus Fund, the Global Growth Focus Fund, the Capital Focus Fund and
the Quality Equity Fund are each authorized to write (i.e., sell) call options
on securities held in its portfolio or securities indices the performance of
which is substantially correlated with securities held in its portfolio. When a
Fund writes a call option, in return for an option premium the Fund gives
another party the right to buy specified securities owned by the Fund at the
exercise price on or before the expiration date, in the case of an option on
securities, or agrees to pay to another party an amount based on any gain in a
specified securities index beyond a specified level on or before the expiration
date, in the case of an option on a securities index. The Fund may write call
options to earn income, through the receipt of option premiums. In the event the
party to which the Fund has written an option fails to exercise its rights under
the option because the value of the underlying securities is less than the
exercise price, the Fund will partially offset any decline in the value of the
underlying securities through the receipt of the option premium. By writing a
call option, however, the Fund limits its ability to sell the underlying
securities, and gives up the opportunity to profit from any increase in the
value of the underlying securities beyond the exercise price, while the option
remains outstanding.

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Global Utility Focus Fund, the Index 500 Fund,
the International Equity Focus Fund, the Global Growth Focus Fund and the
Natural Resources Focus Fund each may also write put options on securities or
securities indices. When the Fund writes a put option, in return for an option
premium the Fund gives another party the right to sell to the Fund a specified
security at the exercise price on or before the expiration date, in the case of
an option on a security, or agrees to pay to another party an amount based on
any decline in a specified securities index below a specified level on or before
the expiration date, in the case of an option on a securities index. The Fund
may write put options to earn income, through the receipt of option premiums. In
the event the party to which the Fund has written an option fails to exercise
its rights under the option because the value of the underlying securities is
greater than the exercise price, the Fund will profit by the amount of the
option premium. By writing a put option, however, the Fund will be obligated to
purchase the underlying security at a price that may be higher than the market
value of the security at the time of exercise as long as the put option is
outstanding, in the case of an option on a security, or make a cash payment
reflecting any decline in the index, in the case of an option on an index.
Accordingly, when the Fund writes a put option it is exposed to a risk of loss
in the event the value of the underlying securities falls below the exercise
price, which loss potentially may substantially exceed the amount of option
premium received by the Fund for writing the put option. The Fund will write a
put option on a security or a securities index only if the Fund would be willing
to purchase the security at the exercise price for investment purposes (in the
case of an option on a security) or is writing the put in connection with
trading strategies involving combinations of options - for example, the sale and
purchase of options with identical expiration dates on the same security or
index but different exercise prices (a technique called a "spread").


                                    Annex B-2
<PAGE>   118

      Each Fund is also authorized to sell call or put options in connection
with closing out call or put options it has previously purchased.

      Other than with respect to closing transactions, a Fund will only write
call or put options that are "covered." A call or put option will be considered
covered if the Fund has segregated assets with respect to such option in the
manner described in "Risk Factors in Options, Futures, and Currency Instruments"
below. A call option will also be considered covered if a Fund owns the
securities it would be required to deliver upon exercise of the option (or, in
the case of option on a securities index, securities which are substantially
correlated with the performance of such index) or owns a call option, warrant or
convertible instrument which is immediately exercisable for, or convertible
into, such security.

      Types of Options. A Fund may engage in transactions in options on
securities or securities indices on exchanges and in the over-the-counter
("OTC") markets. In general, exchange-traded options have standardized exercise
prices and expiration dates and require the parties to post margin against their
obligations, and the performance of the parties' obligations in connection with
such options is guaranteed by the exchange or a related clearing corporation.
OTC options have more flexible terms negotiated between the buyer and the
seller, but generally do not require the parties to post margin and are subject
to greater risk of counterparty default. See "Additional Risk Factors of OTC
Transactions" below.

Futures

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Global Utility Focus Fund, the Index 500 Fund,
the International Equity Focus Fund, the Global Growth Focus Fund and the
Natural Resources Focus Fund may each engage in transactions in futures and
options thereon. Futures are standardized, exchange-traded contracts which
obligate a purchaser to take delivery, and a seller to make delivery, of a
specific amount of a commodity at a specified future date at a specified price.
No price is paid upon entering into a futures contract. Rather, upon purchasing
or selling a futures contract the Fund is required to deposit collateral
("margin") equal to a percentage (generally less than 10%) of the contract
value. Each day thereafter until the futures position is closed, the Fund will
pay additional margin representing any loss experienced as a result of the
futures position the prior day or be entitled to a payment representing any
profit experienced as a result of the futures position the prior day.

      The sale of a futures contract limits a Fund's risk of loss through a
decline in the market value of portfolio holdings correlated with the futures
contract prior to the futures contract's expiration date. In the event the
market value of the portfolio holdings correlated with the futures contract
increases rather than decreases, however, the Fund will realize a loss on the
futures position and a lower return on the portfolio holdings than would have
been realized without the purchase of the futures contract.

      The purchase of a futures contract may protect a Fund from having to pay
more for securities as a consequence of increases in the market value for such
securities during a period when the Fund was attempting to identify specific
securities in which to invest in a market the Fund believes to be attractive. In
the event that such securities decline in value or the Fund determines not to
complete an anticipatory hedge transaction relating to a futures contract,
however, the Fund may realize a loss relating to the futures position.

      A Fund will limit transactions in futures and options on futures to
financial futures contracts (i.e., contracts for which the underlying commodity
is a currency or securities or interest rate index) purchased or sold for
hedging purposes (including anticipatory hedges). Each Fund will further limit
transactions in futures and options on futures to the extent necessary to
prevent the Fund from being deemed a "commodity pool" under regulations of the
Commodity Futures Trading Commission.


                                    Annex B-3
<PAGE>   119

Foreign Exchange Transactions

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Global Utility Focus Fund, the International
Equity Focus Fund, the Natural Resources Focus Fund, the Global Growth Focus
Fund, the Capital Focus Fund and the Quality Equity Fund may engage in spot and
forward foreign exchange transactions and currency swaps, purchase and sell
options on currencies and purchase and sell currency futures and related options
thereon (collectively, "Currency Instruments") for purposes of hedging against
the decline in the value of currencies in which its portfolio holdings are
denominated against the US dollar.

      Forward foreign exchange transactions are OTC contracts to purchase or
sell a specified amount of a specified currency or multinational currency unit
at a price and future date set at the time of the contract. Spot foreign
exchange transactions are similar but require current, rather than future,
settlement. A Fund will enter into foreign exchange transactions only for
purposes of hedging either a specific transaction or a portfolio position. A
Fund may enter into a foreign exchange transaction for purposes of hedging a
specific transaction by, for example, purchasing a currency needed to settle a
security transaction or selling a currency in which the Fund has received or
anticipates receiving a dividend or distribution. A Fund may enter into a
foreign exchange transaction for purposes of hedging a portfolio position by
selling forward a currency in which a portfolio position of the Fund is
denominated or by purchasing a currency in which the Fund anticipates acquiring
a portfolio position in the near future. A Fund may also hedge portfolio
positions through currency swaps, which are transactions in which one currency
is simultaneously bought for a second currency on a spot basis and sold for the
second currency on a forward basis.

      The Funds authorized to engage in Currency Instrument transactions may
also hedge against the decline in the value of a currency against the US dollar
through use of currency futures or options thereon. Currency futures are similar
to forward foreign exchange transactions except that futures are standardized
exchange-traded contracts. See "Futures" above.

      The Funds authorized to engage in Currency Instrument transactions may
also hedge against the decline in the value of a currency against the US dollar
through the use of currency options. Currency options are similar to options on
securities, but in consideration for an option premium the writer of a currency
option is obligated to sell (in the case of a call option) or purchase (in the
case of a put option) a specified amount of a specified currency on or before
the expiration date for a specified amount of another currency. The Fund may
engage in transactions in options on currencies either on exchanges or OTC
markets. See "Types of Options" above and "Additional Risk Factors of OTC
Transactions" below.

      No Fund will speculate in Currency Instruments. Accordingly, a Fund will
not hedge a currency in excess of the aggregate market value of the securities
which it owns (including receivables for unsettled securities sales), or has
committed to or anticipates purchasing, which are denominated in such currency.
A Fund may, however, hedge a currency by entering into a transaction in a
Currency Instrument denominated in a currency other than the currency being
hedged (a "cross-hedge"). The Fund will only enter into a cross-hedge if the
Investment Adviser believes that (i) there is a demonstrable high correlation
between the currency in which the cross-hedge is denominated and the currency
being hedged, and (ii) executing a cross-hedge through the currency in which the
cross-hedge is denominated will be significantly more cost-effective or provide
substantially greater liquidity than executing a similar hedging transaction by
means of the currency being hedged.

      Risk Factors in Hedging Foreign Currency Risks. While a Fund's use of
Currency Instruments to effect hedging strategies is intended to reduce the
volatility of the net asset value of the Fund's shares, the net asset value of
the Fund's shares will fluctuate. Moreover, although Currency Instruments will
be used with the intention of hedging against adverse currency movements,
transactions in Currency Instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the Fund's hedging
strategies will be ineffective. To the extent that a Fund hedges against
anticipated currency movements which do not occur, the Fund may realize losses,
and decrease its total return, as the result of its hedging transactions.
Furthermore, a Fund will only engage in hedging activities from time to time and
may not be engaging in hedging activities when movements in currency exchange
rates occur. It may not be possible for a Fund to hedge against currency
exchange rate movements, even


                                    Annex B-4
<PAGE>   120

if correctly anticipated, in the event that (i) the currency exchange rate
movement is so generally anticipated that the Fund is not able to enter into a
hedging transaction at an effective price, or (ii) the currency exchange rate
movement relates to a market with respect to which Currency Instruments are not
available (such as certain developing markets) and it is not possible to engage
in effective foreign currency hedging.

Risk Factors in Options, Futures, and Currency Instruments

      Use of Strategic Instruments for hedging purposes involves the risk of
imperfect correlation in movements in the value of the Strategic Instruments and
the value of the instruments being hedged. If the value of the Strategic
Instruments moves more or less than the value of the hedged instruments a Fund
will experience a gain or loss which will not be completely offset by movements
in the value of the hedged instruments.

      Each Fund intends to enter into transactions involving Strategic
Instruments only if there appears to be a liquid secondary market for such
instruments or, in the case of illiquid instruments traded in OTC transactions,
such instruments satisfy the criteria set forth below under "Additional Risk
Factors of OTC Transactions." However, there can be no assurance that, at any
specific time, either a liquid secondary market will exist for a Strategic
Instrument or the Fund will otherwise be able to sell such instrument at an
acceptable price. It may therefore not be possible to close a position in a
Strategic Instrument without incurring substantial losses, if at all.

      Certain transactions in Strategic Instruments (e.g., forward foreign
exchange transactions, futures transactions, sales of put options) may expose a
Fund to potential losses which exceed the amount originally invested by the Fund
in such instruments. When a Fund engages in such a transaction, the Fund will
deposit in a segregated account at its custodian liquid securities with a value
at least equal to the Fund's exposure, on a mark-to-market basis, to the
transaction (as calculated pursuant to requirements of the Securities and
Exchange Commission). Such segregation will ensure that the Fund has assets
available to satisfy its obligations with respect to the transaction, but will
not limit the Fund's exposure to loss.

Additional Risk Factors of OTC Transactions; Limitations on the Use of OTC
Strategic Instruments

      Certain Strategic Instruments traded in OTC markets, including indexed
securities and OTC options, may be substantially less liquid than other
instruments in which a Fund may invest. The absence of liquidity may make it
difficult or impossible for the Fund to sell such instruments promptly at an
acceptable price. The absence of liquidity may also make it more difficult for
the Fund to ascertain a market value for such instruments. A Fund will therefore
acquire illiquid OTC instruments (i) if the agreement pursuant to which the
instrument is purchased contains a formula price at which the instrument may be
terminated or sold, or (ii) for which the Investment Adviser anticipates the
Fund can receive on each business day at least two independent bids or offers,
unless a quotation from only one dealer is available, in which case that
dealer's quotation may be used.

      The staff of the Securities and Exchange Commission has taken the position
that purchased OTC options and the assets underlying written OTC options are
illiquid securities. Each Fund has therefore adopted an investment policy
pursuant to which it will not purchase or sell OTC options (including OTC
options on futures contracts) if, as a result of such transactions, the sum of
the market value of OTC options currently outstanding which are held by the
Fund, the market value of the securities underlying OTC call options currently
outstanding which have been sold by the Fund and margin deposits on the Fund's
outstanding OTC options exceeds 15% of the total assets of the Fund, taken at
market value, together with all other assets of the Fund which are deemed to be
illiquid or are otherwise not readily marketable. However, if an OTC option is
sold by the Fund to a dealer in U.S. government securities recognized as a
"primary dealer" by the Federal Reserve Bank of New York and the Fund has the
unconditional contractual right to repurchase such OTC option at a predetermined
price, then the Fund will treat as illiquid such amount of the underlying
securities as is equal to the repurchase price less the amount by which the
option is "in-the-money" (i.e., current market value of the underlying security
minus the option's exercise price).

      Because Strategic Instruments traded in OTC markets are not guaranteed by
an exchange or clearing corporation and generally do not require payment of
margin to the extent that a Fund has unrealized gains in such instruments or has
deposited collateral with its counterparty, the Fund is at risk that its
counterparty will become


                                    Annex B-5
<PAGE>   121

bankrupt or otherwise fail to honor its obligations. A Fund will attempt to
minimize the risk that a counterparty will become bankrupt or otherwise fail to
honor its obligations by engaging in transactions in Strategic Instruments
traded in OTC markets only with financial institutions which have substantial
capital or which have provided the Fund with a third-party guaranty or other
credit enhancement.

Additional Limitations on the Use of Strategic Instruments

      No Fund may use any Strategic Instrument to gain exposure to an asset or
class of assets that it would be prohibited by its investment restrictions from
purchasing directly, except that the Natural Resources Focus Fund may acquire
securities indexed to a precious metal or other natural resource index.

                                YIELD INFORMATION

      Set forth below is yield information for the Class A Shares of the
Domestic Money Market Fund for the seven-day period ended December 31, 1997,
computed to include realized and unrealized gains and losses and also computed
to exclude such gains and losses, and information as to the compounded
annualized yield, excluding gains and losses, for the same periods. The yield
quotations may be of limited use for comparative purposes because they do not
reflect charges imposed at the separate account level which, if included, would
decrease the yield. Because no shares of Class B Common Stock were in issue as
of or prior to December 31, 1997, the yield information below relates to the
Class A Common Stock only. The following yield information should not be
considered indicative of the results that the Fund's Class B Common Stock would
have achieved had the Class B Common Stock been outstanding during the period
shown above because the Class B Common Stock will be subject to a distribution
fee, to which the Class A Common Stock was not subject, at an annual rate of
0.15% of the Fund's average daily net assets attributable to Class B Common
Stock.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Domestic Money Market Fund are to
preserve shareholder capital, to maintain liquidity and to achieve the highest
possible current income consistent with the foregoing objectives by investing in
short-term domestic money market securities. There can be no assurance that the
Domestic Money Market Fund will achieve its investment objectives.

      The Domestic Money Market Fund will invest in short-term U.S. Government
securities, U.S. Government agency securities, domestic depository institution
money instruments (including certificates of deposit, bankers' acceptances, time
deposits and bank notes), short-term debt securities (such as commercial paper),
variable amount master demand notes and insurance company funding agreements,
repurchase and reverse repurchase agreements of U.S. issuers and other money
market instruments. As a matter of fundamental policy, which may be changed only
with the approval of a majority of the Domestic Money Market Fund's outstanding
voting securities, as defined in the Investment Company Act of 1940, as amended
(the "Act" or the "Investment Company Act"), the Domestic Money Market Fund may
not purchase securities of foreign issuers (including Eurodollar or Yankeedollar
bank obligations). U.S. Government securities may be purchased on a forward
commitment basis. The types of money market securities in which the Domestic
Money Market Fund may invest are described more fully in Annex A to the Appendix
to this Prospectus. The Domestic Money Market Fund will be subject to portfolio
maturity, quality and diversification restrictions discussed below.

      In addition, the Domestic Money Market Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended
and which therefore may be subject to restrictions on their transfer or resale.
The Fund may also invest in securities the potential return of which is based on
the change in particular measurements of value or rate, (i.e. indexed
securities). A further discussion of the investments described in this paragraph
and the risks associated with such investments is set forth in the Appendix to
this Prospectus, including Annex B of the Appendix to this Prospectus, which
includes a discussion of certain portfolio strategies relating to indexed
securities.

                             PORTFOLIO RESTRICTIONS

      For purposes of the investment policy of the Domestic Money Market Fund,
the Company defines short-term money market securities as securities having a
maturity of no more than 762 days (25 months) in the case of


                                        3
<PAGE>   125

U.S. Government and agency securities and no more than 397 days (13 months) in
the case of all other securities. Management of the Company expects that
substantially all the assets of the Domestic Money Market Fund will be invested
in securities maturing in less than one year, but at times some portion may have
maturities of up to 25 months. For these purposes, the maturity of a variable
rate security is deemed to be the next coupon date on which the interest rate is
adjusted. The dollar-weighted average maturity of this Fund's portfolio assets
will not exceed 90 days.

      The Domestic Money Market Fund's investments in short-term debt and
depository institution money instruments will be rated, or will be issued by
issuers who have been rated, in one of the two highest rating categories for
short-term debt obligations by a nationally recognized statistical rating
organization (an "NRSRO") or, if not rated, will be of comparable quality as
determined by the Directors of the Company. The Domestic Money Market Fund's
investments in corporate bonds and debentures (which must have maturities at the
date of purchase of 397 days (13 months) or less) will be in issuers which have
received from an NRSRO a rating, with respect to a class of short-term debt
obligations that is comparable in priority and security with the investment, in
one of the two highest rating categories for short-term obligations or, if not
rated, are of comparable quality as determined by the Directors of the Company.
Currently, there are six NRSROs: Duff & Phelps Inc., Fitch Investors Services,
Inc., IBCA Limited and its affiliate IBCA Inc., Moody's Investor's Service,
Inc., Standard & Poor's Ratings Group and Thomson BankWatch.

      A regulation of the Commission limits investments by the Domestic Money
Market Fund in securities issued by any one issuer (other than the U.S.
Government, its agencies or instrumentalities) ordinarily to not more than 5% of
its total assets, or in the event that such securities do not have the highest
rating, not more than 1% of its total assets. In addition, this regulation
requires that not more than 5% of the Fund's total assets be invested in
securities that have a rating lower than the highest rating.

                                YIELD INFORMATION

      Set forth below is yield information for the Class A Shares of the Reserve
Assets Fund for the seven-day period ended December 31, 1997, computed to
include and exclude realized and unrealized gains and losses and also computed
to exclude such gains and losses, and information as to the compounded
annualized yield, excluding gains and losses, for the same periods. The yield
quotations may be of limited use for comparative purposes because they do not
reflect charges imposed at the separate account level which, if included, would
decrease the yield. Because no shares of Class B Common Stock were in issue as
of or prior to December 31, 1997, the yield information below relates to the
Class A Common Stock only. The following yield information should not be
considered indicative of the results that the Fund's Class B Common Stock would
have achieved had the Class B Common Stock been outstanding during the period
shown above because the Class B Common Stock will be subject to a distribution
fee, to which the Class A Common Stock was not subject, at an annual rate of
0.15% of the Fund's average daily net assets attributable to Class B Common
Stock.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Reserve Assets Fund are to preserve
shareholder capital, to maintain liquidity and to achieve the highest possible
current income consistent with the foregoing objectives by investing in
short-term money market securities. There can be no assurance that the Reserve
Assets Fund will achieve its investment objectives.

      The Reserve Assets Fund will invest in short-term U.S. Government
securities, U.S. Government agency securities, depository institution money
instruments (including certificates of deposit, bankers' acceptances, time
deposits and bank notes), short-term debt securities (such as commercial paper),
variable amount master demand notes and insurance company funding agreements,
securities of foreign issuers (including Eurodollar, Yankeedollar and foreign
bank obligations) and repurchase and reverse repurchase agreements. U.S.
Government securities may be purchased on a forward commitment basis. The types
of money market securities in which the Reserve Assets Fund may invest are
described more fully in Annex A to the Appendix to this Prospectus. The Reserve
Assets Fund will be subject to the portfolio maturity, quality and
diversification restrictions discussed below.

      In addition, the Reserve Assets Fund may purchase certain securities that
are not registered under the Securities Act of 1933, as amended and which
therefore may be subject to restrictions on their transfer or resale. The
Reserve Assets Fund may also invest in securities of foreign issuers and in
securities the potential return of which is based on the change in particular
measurements of value or rate (i.e. indexed securities). A further discussion of
the investments described in this paragraph and the risks associated with such
investments is set forth in the Appendix to this Prospectus, including Annex B
of the Appendix to this Prospectus, which includes a discussion of certain
portfolio strategies relating to indexed securities.

                             PORTFOLIO RESTRICTIONS

      For purposes of the investment policy of the Reserve Assets Fund, the
Company defines short-term money market securities as securities having a
maturity of no more than 762 days (25 months) in the case of U.S. Government and
agency securities and no more than 397 days (13 months) in the case of all other
securities. Management of the Company expects that substantially all the assets
of the Reserve Assets Fund will be invested in securities maturing in less than
one year, but at times some portion may have maturities of up to 25 months. For
these purposes, the maturity of a variable rate security is deemed to be the
next coupon date on which the


                                        3
<PAGE>   129

interest rate is adjusted. The dollar-weighted average maturity of this Fund's
portfolio assets will not exceed 90 days.

      The Reserve Asset Fund's investments in short-term debt and depository
institution money instruments will be rated, or will be issued by issuers who
have been rated, in one of the two highest rating categories for short-term debt
obligations by a nationally recognized statistical rating organization (an
"NRSRO") or, if not rated, will be of comparable quality as determined by the
Directors of the Company. The Reserve Assets Fund's investments in corporate
bonds and debentures (which must have maturities at the date of purchase of 397
days (13 months) or less) will be in issuers which have received from an NRSRO a
rating, with respect to a class of short-term debt obligations that is
comparable in priority and security with the investment, in one of the two
highest rating categories for short-term obligations or, if not rated, are of
comparable quality as determined by the Directors of the Company. Currently,
there are six NRSROs: Duff & Phelps Inc., Fitch Investors Services, Inc., IBCA
Limited and its affiliate IBCA Inc., Moody's Investors Service, Inc., Standard &
Poor's Ratings Group and Thomson BankWatch.

      A regulation of the Commission limits investments by the Reserve Assets
Fund in securities issued by any one issuer (other than the U.S. Government, its
agencies or instrumentalities) ordinarily to not more than 5% of its total
assets, or in the event that such securities do not have the highest rating, not
more than 1% of its total assets. In addition, this regulation requires that not
more than 5% of the Reserve Assets Fund's total assets be invested in securities
that have a rating lower than the highest rating.

                       INVESTMENT OBJECTIVES AND POLICIES

      The principal investment objective of the Prime Bond Fund is to provide
shareholders with as high a level of current income as is consistent with the
investment policies of the Fund and with prudent investment management. As a
secondary objective, the Prime Bond Fund seeks capital appreciation when
consistent with its principal objective. There can be no assurance that the
Prime Bond Fund will achieve its investment objectives.

      The Prime Bond Fund invests primarily in securities rated in the top three
rating categories of either Standard & Poor's (AAA, AA and A) or Moody's (Aaa,
Aa and A). Additional information regarding various bond ratings is set forth in
Annex A to the Appendix to this Prospectus. The financial risk of this Fund
should be minimized by the credit quality of the bonds in which it will invest,
but the long maturities that typically provide the best yield will subject the
Fund to possible substantial price changes resulting from market yield
fluctuations. The market prices of fixed-income securities such as those
purchased by the Prime Bond Fund are affected by changes in interest rates
generally. As interest rates rise, the market value of fixed-income securities
will fall, adversely affecting the net asset value of the Fund. The Fund should
be considered a long-term investment and a vehicle for diversification, and not
as a balanced investment program. The Fund may not be appropriate as the
exclusive investment to fund a variable annuity or variable life insurance
contract ("Contract") for all Contract owners.

      Fund management strategy will attempt to mitigate adverse price changes
and optimize favorable price changes through active trading that shifts the
maturity and/or quality structure of the Fund within the overall investment
guidelines. The Prime Bond Fund's investments will vary from time to time
depending upon the judgment of management as to prevailing conditions in the
economy and the securities markets and the prospects for interest rate changes
among different categories of fixed-income securities. The Prime Bond Fund
anticipates that under normal circumstances more than 90% of the assets of the
Fund will be invested in fixed-income securities, including convertible and
non-convertible debt securities and preferred stock. The Prime Bond Fund does
not intend to invest in common stock, rights or other equity securities. Under
unusual market or economic conditions, the Prime Bond Fund for defensive or
other purposes may invest up to 100% of its assets in U.S. Government or
Government agency securities, money market or other fixed-income securities
deemed by the Investment Adviser to be consistent with the objectives of the
Fund, or the Fund may hold its assets in cash.

      In addition, the Prime Bond Fund may purchase certain securities that are
not registered under the Securities Act of 1933, as amended and which therefore
may be subject to restrictions on their transfer or resale. The Fund may also
invest in securities of foreign issuers and may invest in securities the
potential return of which is based on the change in particular measurements of
value or rate (i.e. indexed securities). A further discussion of the investments
described in this paragraph and the risks associated with such investments is
set forth in the Appendix to this Prospectus, including Annex B of the Appendix
to this Prospectus, which includes a discussion of certain portfolio strategies
relating to indexed securities.

                       INVESTMENT OBJECTIVES AND POLICIES

      The primary investment objective of the High Current Income Fund is to
obtain the highest level of current income that is consistent with the
investment policies of the Fund and with prudent investment management. As a
secondary objective, the High Current Income Fund seeks capital appreciation
when consistent with its primary objective. There can be no assurance that the
High Current Income Fund will achieve its investment objectives.

      The High Current Income Fund seeks high current income by investing
principally in fixed-income securities that are rated in the lower rating
categories of the established rating services (Baa or lower by Moody's Investors
Service Inc. ("Moody's") and BBB or lower by Standard & Poor's Ratings Group
("Standard & Poor's"), or in unrated securities of comparable quality.
Securities rated below Baa by Moody's and below BBB by Standard & Poor's are
commonly known as "junk bonds." Additional information regarding various bond
ratings is set forth in Annex A to the Appendix to this Prospectus. The market
price of fixed-income securities such as those purchased by the Fund is affected
by changes in interest rates generally. As interest rates rise, the market value
of fixed-income securities will fall, adversely affecting the net asset value of
the Fund.

      Although they can be expected to provide higher yields, lower-rated
securities such as those purchased by the High Current Income Fund may be
subject to greater market fluctuations and risks of loss of income and principal
than lower-yielding, higher-rated fixed-income securities. Such securities are
generally issued by corporations that are not as financially secure or as
creditworthy as issuers of higher-rated securities. There is, accordingly, a
greater risk that the issuers of higher-yielding securities will not be able to
pay principal and interest on such securities, especially during periods of
adverse economic conditions. Investment in such high-yield securities entails
relatively greater risk of loss of income or principal. The Fund should be
considered a long-term investment and a vehicle for diversification, and not as
a balanced investment program. The Fund may not be appropriate as the exclusive
investment to fund a variable annuity or variable life insurance contract
("Contract") for all Contract owners. See "Investment Objectives and Policies of
the Funds -- Risks of High Yield Securities" in the Appendix to this Prospectus.

      Selection and supervision by the management of the Company regarding
investments in lower-rated fixed-income securities involves continuous analysis
of individual issuers, general business conditions and other factors that may be
too time consuming or too costly for the average investor. The furnishing of
these services does not, of course, guarantee successful results. The analysis
of issuers may include, among other things, historic and current financial
condition, current and anticipated cash flow and borrowing requirements, value
of assets in relation to historical cost, strength of management, responsiveness
to business conditions, credit standing, and current and anticipated results of
operations. Analysis of general business conditions and other factors may
include anticipated changes in economic activity and interest rates, the
availability of new investment opportunities, and the economic outlook for
specific industries. While Merrill Lynch Asset Management, L.P. (the "Investment
Adviser") considers as one factor in its credit analysis the ratings assigned by
the rating services, the Investment Adviser performs its own independent credit
analysis of issuers and consequently, the High Current Income Fund may invest,
without limit, in unrated securities if such securities offer, in the opinion of
the Investment Adviser, a relatively high yield without undue risk. As a result,
the High Current Income Fund's ability to achieve its investment objective may
depend to a greater extent on the Investment Adviser's own credit analysis than
the Funds which invest in higher-rated securities. Although the High Current
Income Fund will invest primarily in lower-rated securities, it will not invest
in securities rated Ca or lower by Moody's and CC or lower by Standard & Poor's
unless the Investment Adviser believes that the financial condition of the
issuer or the protection afforded to the particular securities is stronger than
would otherwise be indicated by such low ratings. However, securities purchased
by the High Current Income Fund may subsequently be downgraded. Such securities
may continue to be held and will be sold only if, in the judgment of the
Investment Adviser, it is advantageous to do so.

      When changing economic conditions and other factors cause the yield
difference between lower-rated and higher-rated securities to narrow, the High
Current Income Fund may purchase higher-rated securities if the Investment
Adviser believes that the risk of loss of income and principal may be
substantially reduced with only a relatively small reduction in yield.


                                        3
<PAGE>   136

      The securities in the High Current Income Fund will be varied from time to
time depending upon the judgment of management as to prevailing conditions in
the economy and the securities markets and the prospects for interest rate
changes among different categories of fixed-income securities. It is anticipated
that under normal circumstances more than 90% of the High Current Income Fund's
assets will be invested in fixed-income securities, including convertible and
non-convertible debt securities and preferred stock. Although it is expected
that, in general, the Fund will not invest in common stocks, rights or other
equity securities, it will acquire or hold such securities (if consistent with
the objectives of the Fund) when such securities are acquired in unit offerings
with fixed-income securities or in connection with an actual or proposed
conversion or exchange of fixed-income securities. In addition, under unusual
market or economic conditions, the High Current Income Fund for defensive
purposes may invest up to 100% of its assets in U.S. Government or Government
agency securities, money market securities or other fixed-income securities
deemed by the Investment Adviser to be consistent with a defensive posture, or
may hold its assets in cash. The yield on such securities may be lower than the
yield on lower-rated fixed-income securities.

      The table below shows the average monthly dollar-weighted market value, by
Standard & Poor's rating category, of the securities held by the High Current
Income Fund during the fiscal year ended December 31, 1997.

                        INVESTMENT OBJECTIVE AND POLICIES

      The Quality Equity Fund seeks to achieve the highest total investment
return, or the aggregate of income and capital value changes, consistent with
prudent risk. To do this, management will shift the emphasis among investment
alternatives for capital growth, capital stability and income as market trends
change. This "fully managed" investment policy distinguishes the Quality Equity
Fund from investment companies which seek either capital growth or income. The
Quality Equity Fund's investment philosophy is based on management's belief that
the structure of the United States economy and its securities markets will
undergo continuous change. The flexibility of the Fund is designed to reduce
overall exposure to risk by achieving below-average volatility in a falling
market and above-average volatility in a rising market. There can be no
assurance that the Quality Equity Fund will achieve its investment objective.
The Fund may employ a variety of instruments and techniques to hedge against
market and currency risk. See Annex B to the Appendix to this Prospectus.

      The Quality Equity Fund's fully managed investment approach will make use
of equity, debt and convertible securities. The majority of the Fund's equity
portfolio will be in the common stocks of large-capitalization, "quality"
companies. For this purpose, "large capitalization" companies are considered to
be those companies with market capitalizations in excess of $500 million.
Management of the Company believes that a quality company is one which conforms
closely to the following criteria: good financial resources, strong balance
sheet, satisfactory rate of return on capital, good industry position and
superior management skills. The earnings of quality companies generally tend to
grow consistently. Whenever market or financial conditions warrant, the Quality
Equity Fund may, in order to reduce risk and achieve the highest total
investment return, invest in non-convertible, long-term debt securities,
including "deep discount" corporate debt securities of investment grade or
issues of fixed-income convertible securities which give the owner the option of
a later exchange for common stock. Management expects that over longer periods
the larger portion of the Quality Equity Fund's portfolio will consist of equity
securities. The Fund should be considered a long-term investment and a vehicle
for diversification, and not as a balanced investment program. The Fund may not
be appropriate as the exclusive investment to fund a variable annuity or
variable life insurance contract ("Contract") for all Contract owners. During
defensive periods, the Fund may invest in U.S. Government and Government agency
securities, money market securities or other fixed-income securities deemed by
the Merrill Lynch Asset Management L.P. (the "Investment Adviser") to be
consistent with a defensive posture, or cash.

Other Investments and Risks

      In addition, the Quality Equity Fund may purchase certain securities that
are not registered under the Securities Act of 1933, as amended and which may
therefore be subject to restrictions on their transfer or resale. The Fund may
also invest in securities of foreign issuers, may from time-to-time be invested
in non-dollar-denominated securities of foreign issuers, and is authorized to
write (i.e., sell) call options on securities held in its portfolio or
securities indices the performance of which is substantially correlated with
securities held in its portfolio. Changes in foreign currency exchange rates may
affect the value of securities in the portfolio and the unrealized appreciation
or depreciation of investments insofar as United States investors are concerned.
Furthermore, the Quality Equity Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments.

      The Quality Equity Fund may engage in transactions, such as currency swaps
and purchasing and selling options on currencies, for purposes of hedging
against the decline in the value of currencies in which its portfolio holdings
are denominated against the US dollar. Although such instruments will be used
with the intention of hedging against adverse currency movements, transactions
in such instruments involve the risk that anticipated currency movements will
not be accurately predicted and that the Fund's hedging strategies will be
ineffective and may cause the Fund to realize losses.

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to options and foreign exchange
transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Special Value Focus Fund is to seek
long-term growth of capital by investing in a diversified portfolio of
securities, primarily common stocks, of relatively small companies that
management of the Company believes have special investment value, and of
emerging growth companies regardless of size. There can be no assurance that the
Special Value Focus Fund will achieve its investment objective. Companies are
selected by management on the basis of their long-term potential for expanding
their size and profitability or for gaining increased market recognition for
their securities. Current income is not a factor in the selection of securities.
The Special Value Focus Fund is intended to provide an opportunity for owners
("Contract Owners") of variable annuity contracts and/or variable life insurance
contracts ("Contracts") who are not ordinarily in a position to perform the
specialized type of research or analysis of small and emerging growth companies.

      Management seeks to identify those small emerging growth companies that
can show significant and sustained increases in earnings over an extended period
of time and are in sound financial condition. Management believes that, while
these companies present above-average risks, properly selected companies of this
type also have the potential to increase their earnings at a rate substantially
in excess of the general growth of the economy. The Special Value Focus Fund
attempts to achieve its objective by focusing on the long-range view of a
company's prospects through a fundamental analysis of its management, financial
structure, product development, marketing ability and other relevant factors.
Full development of these companies frequently takes time and, for this reason,
the Special Value Focus Fund should not be considered as a long-term investment
and not as a vehicle for seeking short-term profits. The Fund should be
considered a long-term investment and a vehicle for diversification, and not as
a balanced investment program.

      Small companies. Management seeks small companies that offer special
investment value in terms of their product or service, research capability, or
other unique attributes, and are relatively undervalued in the marketplace when
compared with similar, but larger, enterprises. These companies typically have
total market capitalizations in the $50-$300 million range and generally are
little known to most individual investors, although some may be dominant in
their respective industries. Underlying this strategy is management's belief
that relatively small companies will continue to have the opportunity to develop
into significant business enterprises. Some such companies may be in a
relatively early stage of development; others may manufacture a new product or
perform a new service. Such companies may not be counted upon to develop into
major industrial companies, but management believes that eventual recognition of
their special value characteristics by the investment community can provide
above-average long-term growth to the portfolio.

      Emerging growth companies. In selecting investments for the Special Value
Focus Fund, management also seeks emerging growth companies that either occupy a
dominant position in an emerging industry or subindustry or have a significant
and growing market share in a large, fragmented industry. Management believes
that capable and flexible management is one of the most important criteria of
emerging growth companies and that such companies should employ sound financial
and accounting policies and also demonstrate effective research, successful
product development and marketing, efficient service and pricing flexibility.
Emphasis is given to companies with rapid historical growth rates, above-average
returns on equity and strong current balance sheets, all of which should enable
the company to finance its continued growth. Management of the Company also
analyzes and weighs relevant factors beyond the company itself, such as the
level of competition in the industry, the extent of governmental regulation, the
nature of labor conditions and other related matters.

      The Special Value Focus Fund emphasizes investments in companies that do
most of their business in the United States and therefore are free of the
currency exchange problems, foreign tax considerations and potential political
and economic upheavals that many multinational corporations face. Moreover, the
size and kinds of markets that they serve make these companies less susceptible
than larger companies to intervention from the federal government by means of
price controls, regulations or litigation.

      While the process of selection and continuous supervision by management
does not, of course, guarantee successful investment results, it does provide
ingredients not available to the average individual due to the time and


                                        4
<PAGE>   144

cost involved. Careful initial selection is particularly important in this area
as many new enterprises have promise but lack certain of the ingredients
necessary to prosper.

      It should be apparent that an investment in a fund such as the Special
Value Focus Fund involves greater risk than is customarily associated with more
established companies. The securities of smaller or emerging growth companies
may be subject to more abrupt or erratic market movements than larger, more
established companies or the market average in general. These companies may have
limited product lines, markets or financial resources, or they may be dependent
upon a limited management group. Because of these factors, management of the
Company believes that shares in the Special Value Focus Fund are suitable for
Contract Owners who are in a financial position to assume above-average
investment risk in search of above-average long-term reward. As indicated, the
Special Value Focus Fund is designed for Contract Owners whose investment
objective is growth rather than income. It is definitely not intended for
exclusive funding of Contracts but is designed for Contract Owners who are
prepared to experience above-average fluctuations in net asset value.

      The securities in which the Special Value Focus Fund invests will often be
traded only in the over-the-counter market or on a regional securities exchange
and may not be traded every day or in the volume typical of trading on a
national securities exchange. As a result, the disposition by the Fund of
portfolio securities to meet redemptions or otherwise may require the Fund to
sell these securities at a discount from market prices or during periods when in
management's judgment such disposition is not desirable or to make many small
sales over a lengthy period of time.

      The investment emphasis of the Special Value Focus Fund is on equities,
primarily common stock and, to a lesser extent, securities convertible into
common stocks and rights to subscribe for common stock, and the Fund will
maintain at least 80% of its net assets invested in equity securities of small
or emerging growth companies except during defensive periods. The Special Value
Focus Fund reserves the right as a defensive measure and to provide for
redemptions to hold other types of securities, including non-convertible
preferred stocks and debt securities, U.S. Government and Government agency
securities, money market securities or other fixed-income securities deemed by
the Investment Adviser to be consistent with a defensive posture, or cash, in
such proportions as, in the opinion of management, prevailing market or economic
conditions warrant.

      In addition, the Special Value Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended and which
therefore may be subject to restrictions on their transfer or resale. The Fund
may also invest in securities of foreign issuers and is authorized to write
(i.e., sell) call options on securities held in its portfolio or securities
indices the performance of which is substantially correlated with securities
held in its portfolio. A further discussion of the investments described in this
paragraph and the risks associated with such investments is set forth in the
Appendix to this Prospectus, including Annex B of the Appendix to this
Prospectus, which includes a discussion of certain portfolio strategies relating
to options.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Natural Resources Focus Fund are to
achieve long-term growth of capital and to protect the purchasing power of
shareholders' capital by investing primarily in a portfolio of equity securities
(e.g., common stocks and securities convertible into common stocks) of domestic
and foreign companies with substantial natural resource assets. This investment
objective is a fundamental policy and may not be changed without a vote of the
majority of outstanding shares of the Natural Resources Focus Fund. The Natural
Resources Focus Fund also may invest in debt, preferred or convertible
securities, the value of which is related to the market value of some natural
resource asset ("asset-based securities"). Management of the Company will seek
to identify companies or asset-based securities it believes are attractively
priced relative to the intrinsic value of the underlying natural resource assets
or are especially well positioned to benefit during particular portions of
inflationary cycles. The Fund should be considered a long-term investment and a
vehicle for diversification, and not as a balanced investment program. The Fund
may not be appropriate as the exclusive investment to fund a variable annuity or
variable life insurance contract ("Contract") for all Contract owners. There can
be no assurance that the Natural Resources Focus Fund will achieve its
investment objectives.

      IN SEEKING TO PROTECT THE PURCHASING POWER OF SHAREHOLDERS' CAPITAL, THE
NATURAL RESOURCES FOCUS FUND HAS RESERVED THE RIGHT, WHEN MANAGEMENT OF THE
COMPANY ANTICIPATES SIGNIFICANT ECONOMIC, POLITICAL OR FINANCIAL INSTABILITY,
SUCH AS HIGH INFLATIONARY PRESSURES OR UPHEAVAL IN THE FOREIGN CURRENCY EXCHANGE
MARKETS, TO INVEST A MAJORITY OF ITS ASSETS IN COMPANIES THAT EXPLORE FOR,
EXTRACT, PROCESS OR DEAL IN GOLD OR IN ASSET-BASED SECURITIES INDEXED TO THE
VALUE OF GOLD BULLION. Such a switch in investment strategies could require the
Fund to liquidate portfolio securities and incur transaction costs. The Company
has been advised by counsel that it is uncertain under the current federal tax
law whether the Fund may concentrate its investments in gold and gold-related
securities without adversely affecting the federal tax status of the Contracts.
Accordingly, management of the Company has determined that the Natural Resources
Focus Fund will not concentrate its investments in such securities until counsel
has advised the Company that such uncertainty has been resolved favorably.

      Management attempts to achieve the investment objectives of the Natural
Resources Focus Fund by seeking to identify securities of companies which, in
its opinion, are undervalued relative to the value of natural resource holdings
of such companies in light of current and anticipated economic or financial
conditions. Natural resource assets are materials derived from natural sources
which have economic value. Management will consider a company to have
substantial natural resource assets when, in its opinion, the company's holdings
of the assets are of such magnitude, when compared to the capitalization,
revenues or operating profits of the company, that changes in the economic value
of the assets are expected to affect the market price of the equity securities
of such company. Generally, a company has substantial natural resource assets
when at least 50% of the non-current assets, capitalization, gross revenues or
operating profits of the company in the most recent or current fiscal year are
involved in or result from directly or indirectly through subsidiaries,
exploring, mining, refining, processing, fabricating, dealing in or owning
natural resource assets. Examples of natural resource assets include precious
metals (e.g., gold, silver and platinum), ferrous and nonferrous metals (e.g.,
iron, steel, aluminum and copper), strategic metals (e.g., uranium and
titanium), hydrocarbons (e.g., coal, oil and natural gas), timber land,
undeveloped real property and agricultural commodities. The Fund presently does
not intend to invest directly in natural resource assets or contracts related
thereto.

      Management of the Company believes that, based upon past performance, the
securities of specific companies that hold different types of substantial
natural resource assets may move relatively independently of one another during
different stages of inflationary cycles due to different degrees of demand for,
or market values of, their respective natural resource holdings during
particular portions of such inflationary cycles. The Fund's fully managed
investment approach enables it to switch its emphasis among various industry
groups depending upon management's outlook with respect to prevailing trends and
developments.

      The Natural Resources Focus Fund at all times, except during defensive
periods, will maintain at least 65% of its total assets invested in companies
with substantial natural resource assets or in asset-based securities. Current


                                        3
<PAGE>   148

income from dividends and interest will not be a primary consideration in
selecting securities. The Fund reserves the right as a temporary defensive
measure and to provide for redemptions, to hold short-term U.S. Government and
Government agency securities, money market securities or other fixed-income
securities deemed by the Investment Adviser to be consistent with a defensive
posture, or cash, in such proportions as, in the opinion of management,
prevailing market or economic conditions warrant.

      As indicated above, under certain circumstances, the Natural Resources
Focus Fund has reserved the right to invest a majority of its assets in
gold-related companies or securities. Based on historic experience, during
periods of economic or financial instability, the securities of such companies
may be subject to extreme price fluctuations, reflecting the high volatility of
gold prices during such periods. In addition, the instability of gold prices may
result in volatile earnings of gold-related companies which, in turn, may affect
adversely the financial condition of such companies. Gold mining companies also
are subject to the risks generally associated with mining operations.

      The major producers of gold include the Republic of South Africa, Russia,
the United States, Australia, Canada, the People's Republic of China and the
Philippines. Sales of gold by Russia and the People's Republic of China are
largely unpredictable and often relate to political and economic considerations
rather than to market forces. Economic, social and political developments within
Russia, the People's Republic of China and the Republic of South Africa may
affect significantly gold production in those countries.

Other Investments and Risks

      In addition, the Natural Resources Focus Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended
and which therefore may be subject to restrictions on their transfer or resale.
The Fund may also engage in transactions for purpose of hedging against the
decline in the value of currencies in which its portfolio holdings are
denominated against the US dollar. The Fund is also authorized to write (i.e.,
sell) and purchase call and put options on securities held in its portfolio, on
securities indicies the performance of which is substantially correlated with
securities held in its portfolio or on securities it intends to purchase, may
engage in transactions in futures, and may invest in securities the potential
return of which is based on the change in particular measurements of value or
rate (i.e., indexed and inverse securities).

      The Natural Resources Focus Fund may also invest in securities of foreign
issuers and may concentrate its investments in one or more countries.
Investments in foreign securities, particularly those of non-governmental
issuers, involve considerations and risks which are not ordinarily associated
with investing in domestic issuers. These considerations and risks include
changes in currency rates, currency exchange control regulations, the
possibility of expropriation, confiscatory taxation, high rates of inflation,
the unavailability of financial information or the difficulty of interpreting
financial information prepared under foreign accounting standards, less
liquidity and more volatility in foreign securities markets, the impact of
political, social or diplomatic developments, and the difficulty of assessing
economic trends in foreign countries. In addition, net investment income earned
by the Fund on a foreign security may be subject to withholding and other taxes
imposed by foreign governments which will reduce the Fund's net investment
income. The Natural Resources Focus Fund may also from time to time be
substantially invested in non-dollar-denominated securities of foreign issuers.
Changes in foreign currency exchange rates may affect the value of securities in
the portfolio and the unrealized appreciation or depreciation of investments
insofar as United States investors are concerned. Furthermore, the Fund's return
on investments in non-dollar-denominated securities may be reduced or enhanced
as a result of changes in foreign currency rates during the period in which the
Fund holds such investments. See "Other Portfolio Strategies--Foreign
Securities" in the Appendix to this Prospectus for special considerations
concerning investments in foreign securities.

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed and inverse securities,
options, futures and foreign exchange transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the American Balanced Fund is to seek a level
of current income and a degree of stability of principal not normally available
from an investment solely in equity securities and the opportunity for capital
appreciation greater than is normally available from an investment solely in
debt securities by investing in a balanced portfolio of fixed income and equity
securities. This investment objective is a fundamental policy and may not be
changed without a vote of the majority of the outstanding shares of the American
Balanced Fund. The American Balanced Fund will seek current income by investing
a portion of its assets in a portfolio of intermediate to long-term debt,
convertible debt, non-convertible and convertible term preferred stock and money
market securities. The American Balanced Fund will seek capital appreciation
primarily by investing a portion of its assets in equity securities, including
perpetual preferred and convertible perpetual preferred stock. At all times the
Fund will maintain at least 25% of its net assets in senior fixed income
securities. As a non-fundamental policy, the Fund is not permitted to invest in
securities of foreign issuers. There can be no assurance that the American
Balanced Fund will achieve its investment objective.

      The Fund will normally limit its allocation of assets to equity securities
to no more than 65% of its net assets. To the extent its equity position exceeds
this limitation, because of changes in the value of portfolio securities or
otherwise, the Fund will seek to reduce its equity position to less than 65% of
net assets by selling such securities at such times and in such amounts as
management of the Company deems appropriate in light of market conditions and
other pertinent factors. See "Dividends, Distributions and Taxes--Tax Treatment
of the Company" in the Appendix to this Prospectus.

      The American Balanced Fund will generally emphasize investment in common
stocks of larger-capitalization issuers and in investment-grade debt
obligations. The Fund may also seek to enhance the return on its common stock
portfolio by writing covered call options listed on United States securities
exchanges. Under unusual market or economic conditions, the Fund for defensive
purposes may invest up to 100% of its assets in short-term U.S. Government or
Government agency securities, money market securities or other fixed-income
securities deemed by the Investment Adviser to be consistent with a defensive
posture, or cash.

      In addition, the American Balanced Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended and which
therefore may be subject to restrictions on their transfer or resale. The Fund
is authorized to write (i.e., sell) call options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio. A further discussion of the
investments described in this paragraph and the risks associated with such
investments is set forth in the Appendix to this Prospectus, including Annex B
of the Appendix to this Prospectus, which includes a discussion of certain
portfolio strategies relating to options.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Strategy Focus Fund is to seek high
total investment return by investing primarily in a portfolio of equity and
fixed income securities, including convertible securities, of U.S. and foreign
issuers. Total investment return consists of interest, dividends, discount
accruals and capital changes, including changes in the value of non-dollar
denominated securities and other assets and liabilities resulting from currency
fluctuations. There can be no assurance that the Global Strategy Focus Fund will
achieve its investment objective. Investing on an international basis involves
special considerations. See "Other Investments and Risks" below.

      The Global Strategy Focus Fund seeks to achieve its objective by investing
primarily in the securities of issuers located in the United States, Canada,
Western Europe, the Far East and Latin America. There are no prescribed limits
on the geographical allocation of the Fund among these regions. Such allocation
will be made primarily on the basis of the anticipated total return from
investments in the securities of issuers wherever located, considering such
factors as the condition and growth potential of the various economies and
securities markets and the issuers domiciled therein, anticipated movements in
interest rates in the various capital markets and in the value of foreign
currencies relative to the US dollar, tax considerations and economic, social,
financial, national and political factors which may affect the climate for
investing within such securities markets. When, in the judgment of Merrill Lynch
Asset Management L.P. (the "Investment Adviser"), economic or market conditions
warrant, the Fund reserves the right to concentrate its investments in one or
more capital markets, including the United States. The Fund should be considered
a long-term investment and a vehicle for diversification, and not as a balanced
investment program. The Fund may not be appropriate as the exclusive investment
to fund a variable annuity or variable life insurance contract ("Contract") for
all Contract owners.

      The corporate debt securities, including convertible debt securities, in
which the Fund may invest will be rated BBB or better by Standard and Poor's
Ratings Group ("Standard & Poor's") or Baa or better by Moody's Investors
Service, Inc. ("Moody's") or, in the opinion of the Investment Adviser, of
comparable quality. The Fund may also invest in debt obligations issued or
guaranteed by sovereign governments, political subdivisions thereof (including
states, provinces and municipalities) or their agencies or instrumentalities or
issued or guaranteed by international organizations designated or supported by
governmental entities to promote economic reconstruction or development
("supranational entities") such as the International Bank for Reconstruction and
Development (the "World Bank") and the European Coal and Steel Community.
Investments in securities of supranational entities are subject to the risk that
member governments will fail to make required capital contributions and that a
supranational entity will thus be unable to meet its obligations.

      When market or financial conditions warrant, the Global Strategy Focus
Fund may invest as a temporary defensive measure up to 100% of its assets in
U.S. Government or Government agency securities, money market securities or
other fixed income securities deemed by the Investment Adviser to be consistent
with a defensive posture, or may hold its assets in cash.

      The Global Strategy Focus Fund may use derivatives in connection with
certain trading strategies. See Annex B of the Appendix to this Prospectus.

Other Investments and Risks

      In addition, the Global Strategy Focus Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended
and which therefore may be subject to restrictions on their transfer or resale.
The Global Strategy Focus Fund may also invest in securities of foreign issuers
and may concentrate its investments in one or more countries. Investments in
foreign securities, particularly those of non-governmental issuers, involve
considerations and risks that are not ordinarily associated with investing in
domestic issuers. These considerations and risks include changes in currency
rates, currency exchange control regulations, the possibility of expropriation,
confiscatory taxation, high rates of inflation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of political, social or diplomatic
developments, and the difficulty of assessing


                                        3
<PAGE>   155

economic trends in foreign countries. In addition, net investment income earned
by the Fund on a foreign security may be subject to withholding and other taxes
imposed by foreign governments, which will reduce the Fund's net investment
income. The Fund may also from time to time be substantially invested in
non-dollar-denominated securities of foreign issuers. Changes in foreign
currency exchange rates may affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. For additional information concerning the risks of investing in
foreign securities, see "Other Portfolio Strategies--Foreign Securities" in the
Appendix to this Prospectus.

      The Global Strategy Focus Fund may engage in transactions, such as
currency swaps and purchasing and selling options on currencies, for purposes of
hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. The Fund is also authorized to
purchase and to write (i.e., sell) call and put options on securities held in
its portfolio, securities indices the performance of which is substantially
correlated with securities held in its portfolio or on securities it intends to
purchase and to purchase put options on securities held in its portfolio and may
also invest in futures and in securities the potential return of which is based
on the change in particular measurements of value of rate (i.e. indexed and
inverse securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed and inverse securities,
options, futures and foreign exchange transactions.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the Basic Value Focus Fund are to seek
capital appreciation and, secondarily, income by investing in securities,
primarily equities, that management of the Fund believes are undervalued and
therefore represent basic investment value. There can be no assurance that the
Basic Value Focus Fund will achieve its investment objectives. The Fund seeks
special opportunities in securities that are selling at a discount, either from
book value or historical price-earnings ratios, or seem capable of recovering
from temporarily out of favor considerations. Particular emphasis is placed on
securities that provide an above-average dividend return and sell at a
below-average price-earnings ratio. The Fund should be considered a long-term
investment and a vehicle for diversification, and not as a balanced investment
program. The Fund may not be appropriate as the exclusive investment to fund a
variable annuity or variable life insurance contract ("Contract") for all
Contract owners.

      The investment policy of the Basic Value Focus Fund is based on the belief
that the pricing mechanism of the securities market lacks total efficiency and
has a tendency to inflate prices of securities in favorable market climates and
depress prices of securities in unfavorable climates. Based on this premise,
management believes that favorable changes in market prices are more likely to
begin when securities are out of favor, earnings are depressed, price-earnings
ratios are relatively low, investment expectations are limited, and there is no
real general interest in the particular security or industry involved. On the
other hand, management believes that negative developments are more likely to
occur when investment expectations are generally high, stock prices are
advancing or have advanced rapidly, price-earnings ratios have been inflated,
and the industry or issue continues to gain new investment acceptance on an
accelerated basis. In other words, management believes that market prices of
securities with relatively high price-earnings ratios are more susceptible to
unexpected adverse developments while securities with relatively low
price-earnings ratios are more favorably positioned to benefit from favorable,
but generally unanticipated, events. This investment policy departs from
traditional philosophy. Management of the Fund believes that the market risk
involved in this policy is moderated somewhat by an emphasis on securities with
above-average dividend returns.

      The current institutionally-dominated market tends to ignore, to some
extent, the numerous secondary issues whose market capitalizations are below
those of the relatively few larger size growth companies. It is expected that
the Basic Value Focus Fund's portfolio generally will have significant
representation in this secondary segment of the market. The basic orientation of
the Fund's investment policies is such that at times a large portion of its
common stock holdings may carry less than favorable research ratings from
research analysts.

      Investment emphasis is on equities, primarily common stock and, to a
lesser extent, securities convertible into common stocks. The Basic Value Focus
Fund also may invest in preferred stocks and non-convertible debt securities
rated investment grade and utilize covered call options with respect to
portfolio securities as described in Annex B to the Appendix of this Prospectus.
The Fund reserves the right as a defensive measure to hold other types of
securities, including U.S. Government and Government agency securities, money
market securities or other fixed-income securities deemed by the Investment
Adviser to be consistent with a defensive posture, or cash, in such proportions
as, in the opinion of management, prevailing market or economic conditions
warrant. The Fund may invest up to 10% of its total assets, taken at market
value at the time of acquisition, in the securities of foreign issuers.

      In addition, the Basic Value Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended and which
therefore may be subject to restrictions on their transfer or resale. The Fund
is also authorized to write (i.e., sell) call options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio. A further discussion of the

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Bond Focus Fund is to seek to
provide shareholders a high total investment return by investing in a global
portfolio of fixed income securities denominated in various currencies,
including multi-national currency units. The Fund will, under normal conditions,
invest at least 90% of its total assets in such fixed income securities. In
pursuing its investment objective, the Global Bond Focus Fund will allocate its
investments among different types of fixed income securities denominated in
various currencies based upon Merrill Lynch Asset Management L.P.'s (the
"Investment Adviser") analysis of the yield, maturity, potential appreciation
and currency considerations affecting such securities. There can be no assurance
that the Global Bond Focus Fund will achieve its investment objective. Investing
on an international basis involves special considerations. See "Other
Investments and Risks" below. The Fund should be considered a long-term
investment and a vehicle for diversification, and not as a balanced investment
program. The Fund may not be appropriate as the exclusive investment to fund a
variable annuity or variable life insurance contract ("Contract") for all
Contract owners.

      The Global Bond Focus Fund may invest in United States and foreign
government and corporate fixed income securities that have a credit rating of A
or better by Standard & Poor's Rating Group ("Standard & Poor's") or by Moody's
Investors Service, Inc. ("Moody's") or commercial paper rated A-1 by Standard &
Poor's or Prime- 1 by Moody's or obligations that the Investment Adviser has
determined to be of similar creditworthiness. The Fund may purchase fixed income
securities issued by United States or foreign corporations or financial
institutions, including debt securities of all types and maturities, convertible
securities and preferred stocks. The Fund also may purchase securities issued or
guaranteed by United States or foreign governments (including foreign states,
provinces and municipalities) or their agencies and instrumentalities
("governmental entities") or issued or guaranteed by international organizations
designated or supported by multiple governmental entities to promote economic
reconstruction or development ("supranational entities").

      International Investing. The Global Bond Focus Fund may invest in fixed
income securities denominated in any currency or multinational currency unit. An
illustration of a multinational currency unit is the European Currency Unit
("ECU"), which is a "basket" consisting of specified amounts of the currencies
of certain of the twelve member states of the European Community, a Western
European economic cooperative association including France, Germany, the
Netherlands and the United Kingdom. The specific amounts of currencies
comprising the ECU may be adjusted by the Council of Ministers of the European
Community to reflect changes in relative values of the underlying currencies.
The Investment Adviser does not believe that such adjustments will adversely
affect holders of ECU-denominated obligations or the marketability of such
securities. European supranational entities (described further below), in
particular, issue ECU-denominated obligations. The Fund may invest in securities
denominated in the currency of one nation although issued by a governmental
entity, corporation or financial institution of another nation. For example, the
Fund may invest in a British pound sterling-denominated obligation issued by a
United States corporation. Such investments involve credit risks associated with
the issuer and currency risks associated with the currency in which the
obligation is denominated. See "Other Investments and Risks" below.

      It is anticipated that under current conditions the Global Bond Focus Fund
will invest primarily in marketable securities denominated in the currencies of
the United States, Canada, Western European nations, New Zealand and Australia,
as well as in ECUs. Further, it is anticipated that such securities will be
issued primarily by entities located in such countries and by supranational
entities. Under normal conditions, the Fund's investments will be denominated in
at least three currencies or multinational currency units. Under certain adverse
conditions, the Fund may restrict the financial markets or currencies in which
its assets will be invested. The Fund presently intends to invest its assets
solely in the United States financial markets or United States
dollar-denominated obligations only for temporary defensive purposes.

      The obligations of foreign governmental entities have various kinds of
government support and include obligations issued or guaranteed by foreign
governmental entities with taxing power. These obligations may or may not be
supported by the full faith and credit of a foreign government. The Global Bond
Focus Fund will invest in foreign government securities of issuers considered
stable by the Investment Adviser. While investments in foreign government debt
securities may involve special risks, the Investment Adviser does not believe
that the credit risk


                                        3
<PAGE>   163

inherent in the obligations of stable foreign governments is significantly
greater than that of U.S. Government securities. See "Other Portfolio Strategies
- -- Foreign Securities" in the Appendix to this Prospectus.

      Supranational entities include international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Steel and Coal Community, the Asian
Development Bank and the Inter--American Development Bank. The government
members, or "stockholders," usually make initial capital contributions to the
supranational entity and in many cases are committed to make additional capital
contributions if the supranational entity is unable to repay its borrowings.

      Allocation of Investments. In seeking to meet its investment objective,
high current income will be only one of the factors that the Investment Adviser
will consider in selecting portfolio securities for the Global Bond Focus Fund.
As a general matter, in evaluating investments for the Fund, the Investment
Adviser will consider, among other factors, the relative levels of interest
rates prevailing in various countries, the potential appreciation of such
investments in their denominated currencies and, for debt instruments not
denominated in US dollars, the potential movement in the value of such
currencies compared to the US dollar. Additionally, the Fund, in seeking capital
appreciation, may invest in relatively low yielding instruments in expectation
of favorable currency fluctuations or interest rate movements, thereby
potentially reducing the Fund's current yield. In seeking income, the Fund may
invest in short term instruments with relatively high yields (as compared to
other debt securities) meeting the Fund's investment criteria, notwithstanding
that the Fund may not anticipate that such instruments will experience
substantial capital appreciation.

      The average maturity of the Global Bond Focus Fund's portfolio securities
will vary based upon the Investment Adviser's assessment of economic and market
conditions. As with all fixed income securities, changes in market yields will
affect the Fund's asset value as the prices of portfolio securities generally
increase when interest rates decline and decrease when interest rates rise.
Prices of longer-term securities generally fluctuate more in response to
interest rate changes than do shorter-term securities. The Global Bond Focus
Fund does not expect the average maturity of its portfolio to exceed ten years.

Other Investments and Risks

      In addition, the Global Bond Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended and which
therefore may be subject to restrictions on their transfer or resale. The Fund
may invest in securities of foreign issuers. Investments in foreign securities,
particularly those of non-governmental issuers, involve considerations and risks
that are not ordinarily associated with investing in domestic issuers. These
considerations and risks include changes in currency rates, currency exchange
control regulations, the possibility of expropriation, confiscatory taxation,
high rates of inflation, the unavailability of financial information or the
difficulty of interpreting financial information prepared under foreign
accounting standards, less liquidity and more volatility in foreign securities
markets, the impact of political, social or diplomatic developments, and the
difficulty of assessing economic trends in foreign countries. In addition, net
investment income earned by the Fund on a foreign security may be subject to
withholding and other taxes imposed by foreign governments, which will reduce
the Fund's net investment income. The Global Bond Focus Fund may also from time
to time be substantially invested in non-dollar-denominated securities of
foreign issuers. The value of the Global Bond Focus Fund's holdings denominated
in currencies other than the US dollar and the unrealized appreciation or
depreciation of those investments insofar as United States investors are
concerned will be affected by changes in the value of such currencies relative
to the US dollar. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. Such currency fluctuations may have a substantial impact on the
value of the Fund's holdings. The Fund may engage in transactions, such as
currency swaps and purchasing and selling options on currencies, for purposes of
hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the intention of hedging against adverse currency movements,
transactions in such instruments involve the risk that anticipated


                                        4
<PAGE>   164

currency movements will not be accurately predicted and that the Fund's hedging
strategies will be ineffective and may cause the Fund to realize losses. The
Global Bond Focus Fund may also invest in debt securities issued by foreign
governments. See "Other Portfolio Strategies -- Foreign Securities" in the
Appendix and Annex B of the Appendix to this Prospectus.

      The Global Bond Focus Fund is also authorized to write (i.e., sell) and to
purchase call and put options on securities held in its portfolio or securities
indices the performance of which is substantially correlated with securities
held in its portfolio, may engage in transactions in futures and may invest in
securities the potential return of which is based on the change in particular
measurements of value or rate (i.e., indexed securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed securities, options and
futures.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Utility Focus Fund is to seek both
capital appreciation and current income through investment of at least 65% of
its total assets in equity and debt securities issued by domestic and foreign
companies which are, in the opinion of Merrill Lynch Asset Management, L.P. (the
"Investment Adviser"), primarily engaged in the ownership or operation of
facilities used to generate, transmit or distribute electricity,
telecommunications, gas or water. There can be no assurance that the Global
Utility Focus Fund will achieve its investment objective. The Fund may employ a
variety of instruments and techniques to enhance income and to hedge against
market and currency risk, as described in Annex B to the Appendix to this
Prospectus. Investing on an international basis involves special considerations.
See "Other Investments and Risks" below. The Fund should be considered a
long-term investment and a vehicle for diversification, and not as a balanced
investment program. The Fund may not be appropriate as the exclusive investment
to fund a variable annuity or variable life insurance contract ("Contract") for
all Contract owners.

      The Global Utility Focus Fund at all times, except during temporary
defensive periods, will maintain at least 65% of its total assets invested in
equity and debt securities issued by domestic and foreign companies in the
utilities industries. The Fund reserves the right to hold, as a temporary
defensive measure or as a reserve for redemptions, short-term U.S. Government
securities, money market securities, including repurchase agreements, or cash in
such proportions as, in the opinion of the Investment Adviser, prevailing market
or economic conditions warrant. Except during temporary defensive periods, such
securities or cash will not exceed 20% of its total assets. Under normal
circumstances, the Fund will invest at least 65% of its total assets in issuers
domiciled in at least three countries, one of which may be the United States,
although the Investment Adviser expects the Fund's portfolio to be more
geographically diversified. Under normal conditions, it is anticipated that the
percentage of assets invested in U.S. securities will be higher than that
invested in securities of any other single country. It is possible that at times
the Fund may have 65% or more of its total assets invested in foreign
securities.

      The Global Utility Focus Fund will invest in common stocks (including
preferred or debt securities convertible into common stocks), preferred stocks
and debt securities. The relative weightings among common stocks, debt
securities and preferred stocks will vary from time to time based upon the
Investment Adviser's judgment of the extent to which investments in each
category will contribute to meeting the Fund's investment objective. Fixed
income securities in which the Fund will invest generally will be limited to
those rated investment grade, that is, rated in one of the four highest rating
categories by Standard & Poor's Ratings Group ("Standard & Poor's") or Moody's
Investors Service, Inc. ("Moody's") (i.e., securities rated at least BBB by
Standard & Poor's or Baa by Moody's), or deemed to be of equivalent quality in
the judgment of the Investment Adviser. Securities rated Baa by Moody's are
described by it as having speculative characteristics and, according to Standard
& Poor's, fixed income securities rated BBB normally exhibit adequate protection
parameters, although adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to pay interest and repay principal.
The Fund's commercial paper investments at the time of purchase will be rated
"A-1" or "A-2" by Standard & Poor's or "Prime-1" or "Prime-2" by Moody's or, if
not rated, will be of comparable quality as determined by the Investment
Adviser. The Fund may also invest up to 5% of its total assets at the time of
purchase in fixed income securities having a minimum rating no lower than Caa by
Moody's or CCC by Standard & Poor's. The Fund may, but need not, dispose of any
security if it is subsequently downgraded. For a description of ratings of debt
securities, see Annex A to the Appendix to this Prospectus.

      A change in prevailing interest rates is likely to affect the Fund's net
asset value because prices of debt and equity securities of utility companies
tend to increase when interest rates decline and decrease when interest rates
rise.

      Utility Industries--Description and Risks. Under normal circumstances, the
Global Utility Focus Fund will invest at least 65% of its total assets in common
stocks (including preferred or debt securities convertible into common stocks),
debt securities and preferred stocks of domestic and/or foreign companies in the
utility industries. To meet its objective of current income, the Fund may invest
in domestic utility companies that pay higher than average dividends, but have a
lesser potential for capital appreciation. The average dividend yields of common
stocks issued by domestic utility companies historically have significantly
exceeded those of industrial companies'


                                        3
<PAGE>   168

common stocks, while the prices of domestic utility stocks have tended to be
less volatile than stocks of industrial companies. The Investment Adviser
believes that the average dividend yields of common stocks issued by foreign
utility companies have also historically exceeded those of foreign industrial
companies' common stocks. To pursue its objective of capital appreciation, the
Fund may invest in foreign utility companies that pay lower than average
dividends, but have a greater potential for capital appreciation.

      The utility companies in which the Fund will invest include companies that
are, in the opinion of the Investment Adviser, primarily engaged in the
ownership or operation of facilities used to generate, transmit or distribute
electricity, telecommunications, gas or water.

      Investments in utility industries bear certain risks, including difficulty
in obtaining an adequate return on invested capital, difficulty in financing
large construction programs during an inflationary period, restrictions on
operations and increased cost and delays attributable to environmental
considerations and regulation, difficulty in raising capital in adequate amounts
on reasonable terms in periods of high inflation and unsettled capital markets,
technological innovations which may render existing plants, equipment or
products obsolete, the potential impact of natural or man-made disasters,
increased costs and reduced availability of certain types of fuel, occasionally
reduced availability and high costs of natural gas for resale, the effects of
energy conservation, the effects of a national energy policy and lengthy delays
and greatly increased costs and other problems associated with design,
construction, licensing, regulation and operation of nuclear facilities for
electric generation, including, among other considerations, the problems
associated with the use of radioactive materials and the disposal of radioactive
wastes. There are substantial differences between the regulatory practices and
policies of various jurisdictions, and any given regulatory agency may make
major shifts in policy from time to time. There is no assurance that regulatory
authorities will, in the future, grant rate increases or that such increases
will be adequate to permit the payment of dividends on common stocks.
Additionally, existing and possible future regulatory legislation may make it
even more difficult for these utilities to obtain adequate relief. Certain of
the issuers of securities in the portfolio may own or operate nuclear generating
facilities. Governmental authorities may from time to time review existing
policies, and impose additional requirements governing the licensing,
construction and operation of nuclear power plants.

      Utility companies in the United States and in foreign countries are
generally subject to regulation. In the United States, most utility companies
are regulated by state and/or federal authorities. Such regulation is intended
to ensure appropriate standards of service and adequate capacity to meet public
demand. Generally, prices are also regulated in the United States and in foreign
countries with the intention of protecting the public while ensuring that the
rate of return earned by utility companies is sufficient to allow them to
attract capital in order to grow and continue to provide appropriate services.
There can be no assurance that such pricing policies or rates of return will
continue in the future. The nature of regulation of the utility industries is
evolving both in the United States and in foreign countries. Changes in
regulation in the United States increasingly allow utility companies to provide
services and products outside their traditional geographic areas and lines of
business, creating new areas of competition within the industries. In some
instances, utility companies are operating on an unregulated basis. Because of
trends toward deregulation and the evolution of independent power producers as
well as new entrants to the field of telecommunications, non-regulated providers
of utility services have become a significant part of their respective
industries. The Investment Adviser believes that the emergence of competition
and deregulation will result in certain utility companies being able to earn
more than their traditional regulated rates of return, while others may be
forced to defend their core businesses from increased competition and may be
less profitable. The Investment Adviser seeks to take advantage of favorable
investment opportunities that are expected to arise from these structural
changes. Of course, there can be no assurance that favorable developments will
occur in the future.

      Foreign utility companies are also subject to regulation, although such
regulations may or may not be comparable to that in the United States. Foreign
utility companies may be more heavily regulated by their respective governments
than utilities in the United States and, as in the U.S., generally are required
to seek government approval for rate increases. In addition, many foreign
utilities use fuels that cause more pollution than those used in the United
States, which may require such utilities to invest in pollution control
equipment to meet any proposed pollution restrictions. Foreign regulatory
systems vary from country to country and may evolve in ways different from
regulation in the United States.

      The principal sectors of the global utility industries are discussed
below.

      Electric. The electric utility industry consists of companies that are
engaged principally in the generation, transmission and sale of electric energy,
although many also provide other energy-related services. Domestic electric
utility companies, in general, recently have been favorably affected by lower
fuel and financing costs and the full or near completion of major construction
programs. In addition, certain of these companies generate cash flows in excess
of current operating expenses and construction expenditures, permitting some
degree of diversification into unregulated businesses. Some electric utilities
have also taken advantage of the right to sell power outside of their
traditional geographic areas. Electric utility companies have historically been
subject to the risks associated with increases in fuel and other operating
costs, high interest costs on borrowings needed for capital construction
programs, costs associated with compliance with environmental and safety
regulations and changes in the regulatory climate. As interest rates have
declined, many utilities have refinanced high cost debt and in doing so have
improved their fixed charges coverage. Regulators, however, have lowered allowed
rates of return as interest rates have declined and thereby caused the benefits
of the rate declines to be shared wholly or in part with customers.

      In the United States, the construction and operation of nuclear power
facilities is subject to increased scrutiny by, and evolving regulations of, the
Nuclear Regulatory Commission and state agencies having comparable jurisdiction.
Increased scrutiny might result in higher operating costs and higher capital
expenditures, with the risk that the regulators may disallow inclusion of these
costs in rate authorizations or the risk that a company may not be permitted to
operate or complete construction of a facility. In addition, operators of
nuclear power plants may be subject to significant costs for disposal of nuclear
fuel and for decommissioning of such plants.

      In October 1993, Standard & Poor's stiffened its debt-ratings formula for
the electric utility industry, stating that the industry is in long-term
decline. In addition, Moody's stated that it expected a drop in the next three
years in its average credit ratings for the industry. Reasons set forth for
these outlooks included slowing demand and increasing cost pressures as a result
of competition from rival providers.

      Telecommunications. The telephone industry is large and highly
concentrated. Companies that distribute telephone services and provide access to
the telephone networks comprise the greatest portion of this segment. Telephone
companies in the United States are still experiencing the effects of the breakup
of American Telephone & Telegraph Company, which occurred in 1984. Since 1984,
companies engaged in telephone communication services have expanded their
non-regulated activities into other businesses, including cellular telephone
services, data processing, equipment retailing, computer software and hardware
services, and financial services. This expansion has provided significant
opportunities for certain telephone companies to increase their earnings and
dividends at faster rates than had been allowed in traditional regulated
businesses. Increasing competition, technological innovations and other
structural changes, however, could adversely affect the profitability of such
utilities. Technological breakthroughs and the merger of telecommunications with
video and entertainment is now associated with the expansion of the role of
cable companies as providers of utility services in the telecommunications
industry and the competitive response of traditional telephone companies. Given
mergers and certain marketing tests currently underway, it is likely that both
traditional telephone companies and cable companies will soon provide a greatly
expanded range of utility services, including two-way video and informational
services.

      Gas. Gas transmission companies and gas distribution companies are also
undergoing significant changes. In the United States, interstate transmission
companies are regulated by the Federal Energy Regulatory Commission, which is
reducing its regulation of the industry. Many companies have diversified into
oil and gas exploration and development, making returns more sensitive to energy
prices. In the recent decades, gas utility companies have been adversely
affected by disruptions in the oil industry and have also been affected by
increased concentration and competition.

      Water. Water supply utilities are companies that collect, purify,
distribute and sell water. In the United States and around the world, the
industry is highly fragmented because most of the supplies are owned by local
authorities. Companies in this industry are generally mature and are
experiencing little or no per capita volume growth.

      Investment Outside the Utility Industries. The Global Utility Focus Fund
is permitted to invest up to 35% of its assets in securities of issuers that are
outside the utility industries. Such investments may include common stocks, debt
securities or preferred stocks and will be selected to meet the Fund's
investment objective of both capital appreciation and current income. These
securities may be issued by either U.S. or non-U.S. companies. Some of these
issuers may be in industries related to utility industries and, therefore, may
be subject to similar risks. Securities that are issued by foreign companies or
are denominated in foreign currencies are subject to certain risks. See "Other
Investments and Risks" below.

      The Global Utility Focus Fund is also permitted to invest in securities
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
and in securities issued or guaranteed by foreign governments. Foreign
government securities are typically denominated in foreign currencies and are
subject to the currency fluctuation and other risks of foreign securities
investments. The foreign government securities in which the Fund intends to
invest generally will consist of obligations supported by national, state or
local governments or similar political subdivisions. Foreign government
securities also include debt obligations of supranational entities, including
international organizations designated or supported by governmental entities to
promote economic reconstruction or development and international banking
institutions and related government agencies. Examples include the International
Bank for Reconstruction and Development (the "World Bank"), the European
Investment Bank, the Asian Development Bank and the Inter-American Development
Bank.

      Foreign government securities also include debt securities of
"quasi-governmental agencies" and debt securities denominated in multinational
currency units. An example of a multinational currency unit is the European
Currency Unit. A European Currency Unit represents specified amounts of the
currencies of certain of the twelve member states of the European Economic
Community. Debt securities of quasi-governmental agencies are issued by entities
owned by either a national or local government or are obligations of a political
unit that is not backed by the national government's full faith and credit and
general taxing powers. Foreign government securities will not be considered
government securities for purposes of determining the Fund's compliance with
diversification and concentration policies.

Other Investments and Risks

      In addition, the Global Utility Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended and which
therefore may be subject to restrictions on their transfer or resale. The Global
Utility Focus Fund may also invest in securities of foreign issuers. Investments
in foreign securities, particularly those of non-governmental issuers, involve
considerations and risks that are not ordinarily associated with investing in
domestic issuers. These considerations and risks include changes in currency
rates, currency exchange control regulations, the possibility of expropriation,
confiscatory taxation, high rates of inflation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of political, social or diplomatic
developments, and the difficulty of assessing economic trends in foreign
countries. In addition, net investment income earned by the Fund on a foreign
security may be subject to withholding and other taxes imposed by foreign
governments which will reduce the Fund's net investment income. The Global
Utility Focus Fund may from time to time be substantially invested in
non-dollar-denominated securities of foreign issuers. Changes in the foreign
currency exchange rates may affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. The Global Utility Focus Fund may also engage in transactions, such
as currency swaps and purchasing and selling options on currencies, for purposes
of hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the intention of hedging against adverse currency movements,
transactions in such instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the Fund's hedging
strategies will be ineffective and may cause the Fund to realize losses. See
"Other Portfolio Strategies -- Foreign Securities" in the Appendix to this
Prospectus.

      The Global Utility Focus Fund may from time to time enter into standby
commitment agreements, engage in transactions in futures, invest in securities
the potential return of which is based on the change in particular measurements
of value or rate (i.e. indexed securities), and, is authorized to write (i.e.,
sell) call and put options and purchase put options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio, and to purchase put options on
securities held in its portfolio.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives of the International Equity Focus Fund are to
seek capital appreciation and, secondarily, income by investing in a diversified
portfolio of equity securities of issuers located in countries other than the
United States. Under normal conditions, at least 65% of the Fund's net assets
will be invested in such equity securities and at least 65% of the Fund's total
assets will be invested in the securities of issuers from at least three
different foreign countries. The investment objective of the Fund is a
fundamental policy and may not be changed without approval of a majority of the
Fund's outstanding shares. There can be no assurance that the International
Equity Focus Fund will achieve its investment objectives. The Fund may employ a
variety of investments and techniques to hedge against market and currency risk.
See Annex B of the Appendix to this Prospectus. Investing on an international
basis involves special considerations. Investing in smaller capital markets
entails the risk of significant volatility in the Fund's security prices. The
Fund is designed for investors seeking to complement their U.S. holdings through
foreign investments. The Fund should be considered a long-term investment and a
vehicle for diversification, and not as a balanced investment program. The Fund
may not be appropriate as the exclusive investment to fund a variable annuity or
variable life insurance contract ("Contract") for all Contract owners.

      The International Equity Focus Fund will invest in an international
portfolio of securities of foreign companies located throughout the world. While
there are no prescribed limits on the geographic allocation of the Fund's
investments, management of the Fund anticipates that a substantial portion of
its assets will be invested in the developed countries of Europe and the Far
East. For the reasons stated below, management of the Fund will give special
attention to investment opportunities in the developing countries of the world,
including, but not limited to Latin America, the Far East and Eastern Europe. It
is anticipated that a significant portion of the Fund's assets may be invested
in such developing countries.

      The allocation of the International Equity Focus Fund's assets among the
various foreign securities markets will be determined by Merrill Lynch Asset
Management, L.P. (the "Investment Adviser") based primarily on its assessment of
the relative condition and growth potential of the various economies and
securities markets, currency and taxation considerations and other pertinent
financial, social, national and political factors. Within such allocations, the
Investment Adviser will seek to identify equity investments in each market that
are expected to provide a total return that equals or exceeds the return of such
market as a whole.

      A significant portion of the International Equity Focus Fund's assets may
be invested in developing countries. This allocation of the Fund's assets
reflects the belief that attractive investment opportunities may result from an
evolving long-term international trend favoring more market-oriented economies,
a trend that may especially benefit certain developing countries with smaller
capital markets. This trend may be facilitated by local or international
political, economic or financial developments that could benefit the capital
markets of such countries. Certain such countries, particularly so-called
"emerging" countries (such as Malaysia, Mexico and Thailand), which may be in
the process of developing more market-oriented economies, may experience
relatively high rates of economic growth. Because of the general illiquidity of
the capital markets in certain developing countries, the Fund may invest in a
relatively small number of leading or relatively actively traded companies in
the capital markets of such a country in the expectation that the investment
experience of the securities of such companies will substantially represent the
investment experience of that country's capital markets as a whole.

      While the International Equity Focus Fund will primarily emphasize
investments in common stock, the Fund may also invest in preferred stocks,
convertible debt securities and other instruments the return on which is linked
to the performance of a common stock or a basket or index of common stocks
(collectively, "equity securities"). The Fund may also invest in non-equity
securities, including debt securities, cash or cash equivalents denominated in
US dollars or foreign currencies and short-term securities, including money
market instruments. Under certain adverse investment conditions, for defensive
purposes, the Fund may restrict the markets in which its assets will be invested
and may increase the proportion of assets invested in short-term obligations of
U.S. issuers. Investments made for defensive purposes will be maintained only
during periods in which the Investment Adviser determines that economic or
financial conditions are adverse for holding or being fully invested in equity
securities of foreign issuers.


                                        3
<PAGE>   175

      The International Equity Focus Fund also may invest up to 35% of its net
assets in longer-term, non-convertible debt securities emphasizing debt
securities which offer the opportunity for capital appreciation. Capital
appreciation in debt securities may arise as a result of a favorable change in
relative foreign exchange rates, in relative interest rate levels, or in the
creditworthiness of issuers. In accordance with its investment objective, the
Fund will not seek to benefit from anticipated short-term fluctuations in
currency exchange rates. The Fund may, from time to time, invest in debt
securities with relatively high yields (as compared to other debt securities
meeting the Fund's investment criteria), notwithstanding that the Fund may not
anticipate that such securities will experience substantial capital
appreciation. Such income can be used, however, to offset the operating expenses
of the Fund.

      The International Equity Focus Fund may invest in debt securities issued
or guaranteed by foreign governments (including foreign states, provinces and
municipalities) or their agencies and instrumentalities ("governmental
entities"), issued or guaranteed by international organizations designated or
supported by multiple foreign governmental entities (which are not obligations
of foreign governments) to promote economic reconstruction or development
("supranational entities"), or issued by foreign corporations or financial
institutions.

      Supranational entities include international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Steel and Coal Community, the Asian
Development Bank and the Inter-American Development Bank. The governmental
members, or "stockholders," usually make initial capital contributions to the
supranational entity and in many cases are committed to make additional capital
contributions if the supranational entity is unable to repay its borrowings.

Other Investments and Risks

      In addition, the International Equity Focus Fund may purchase certain
securities that are not registered under the Securities Act of 1933, as amended
and which therefore may be subject to restrictions on their transfer or resale.

      The International Equity Focus Fund has established no rating criteria for
the debt securities in which it may invest, and such securities may not be rated
at all for creditworthiness. Securities rated in the medium to lower rating
categories of nationally recognized statistical rating organizations and unrated
securities of comparable quality are predominantly speculative with respect to
the capacity to pay interest and repay principal in accordance with the terms of
the security and generally involve a greater volatility of price than securities
in higher rating categories. In purchasing such securities, the Fund will rely
on the Investment Adviser's judgment, analysis and experience in evaluating the
creditworthiness of an issuer of such securities. The Investment Adviser will
take into consideration, among other things, the issuer's financial resources,
its sensitivity to economic conditions and trends, its operating history, the
quality of the issuer's management and regulatory matters. The Fund does not
intend to purchase debt securities that are in default or that the Investment
Adviser believes will be in default. See "Risks of High Yield Securities" in the
Appendix to this Prospectus.

      The Fund may invest in securities of foreign issuers. Investments in
foreign securities, particularly those of non-governmental issuers, involve
considerations and risks that are not ordinarily associated with investing in
domestic issuers. These considerations and risks include changes in currency
rates, currency exchange control regulations, the possibility of expropriation,
confiscatory taxation, high rates of inflation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of political, social or diplomatic
developments, and the difficulty of assessing economic trends in foreign
countries. In addition, net investment income earned by the Fund on a foreign
security may be subject to withholding and other taxes imposed by foreign
governments, which will reduce the Fund's net investment income. The Fund may
from time to time be substantially invested in non-dollar-denominated securities
of foreign issuers. Changes in foreign currency exchange rates may affect the
value of securities in the portfolio and the unrealized appreciation or
depreciation of investments insofar as United States investors are concerned.
Furthermore, the Fund's return on investments in non-dollar-denominated
securities may be reduced or enhanced as a result of changes in foreign currency
rates during


                                        4
<PAGE>   176

the period in which the Fund holds such investments. See "Other Portfolio
Strategies -- Foreign Securities" in the Appendix to this Prospectus.

      The International Equity Focus Fund may engage in transactions, such as
currency swaps and purchasing and selling options on currencies, for purposes of
hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the intention of hedging against adverse currency movements,
transactions in such instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the International Equity
Focus Fund's hedging strategies will be ineffective and may cause the Fund to
realize losses.

      The International Equity Focus Fund may also invest a significant portion
of its assets in securities of foreign issuers in smaller capital markets.
Foreign investments involve risks that are often heightened for investments in
smaller capital markets. There may be less publicly available information about
an issuer in a smaller capital market than would be available about a United
States company, and it may not be subject to accounting, auditing and financial
reporting standards and requirements comparable to those of United States
companies. Furthermore, smaller capital markets have substantially less volume
than United States markets so securities in many smaller capital markets are
less liquid and their prices may be more volatile than securities of comparable
United States companies. As a result, traditional investment measurements, such
as price/earnings ratios, as used in the United States, may not be applicable in
certain capital markets. See "Other Portfolio Strategies -- Foreign Securities"
in the Appendix to this Prospectus.

      The International Equity Focus Fund is also authorized to write (i.e.,
sell) and purchase call and put options on securities held in its portfolio or
securities indices the performance of which is substantially correlated with
securities held in its portfolio, engage in transactions in futures and options
thereon, and may invest in securities the potential return of which is based on
the change in particular measurements of value or rate (i.e. indexed and inverse
securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed and inverse securities,
options, futures and foreign exchange transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Developing Capital Markets Focus Fund is
to seek long-term capital appreciation by investing in securities, principally
equities, of issuers in countries having smaller capital markets. Under normal
conditions, at least 65% of the Fund's net assets will be invested in such
equity securities. The investment objective of the Fund is a fundamental policy
and may not be changed without approval of a majority of the Fund's outstanding
shares. There can be no assurance that the Fund will achieve its investment
objective. The Developing Capital Markets Focus Fund may employ a variety of
investments and techniques to hedge against market and currency risk. See Annex
B to the Appendix to this Prospectus. Investing on an international basis
involves special considerations. Investing in smaller capital markets entails
the risk of significant volatility in the Fund's security prices. See "Other
Investments and Risks" below. The Fund should be considered a long-term
investment and a vehicle for diversification, and not as a balanced investment
program. The Fund may not be appropriate as the exclusive investment to fund a
variable annuity or variable life insurance contract ("Contract") for all
Contract owners.

      For purposes of its investment objective, the Developing Capital Markets
Focus Fund considers countries having smaller capital markets to be all
countries other than the four countries having the largest equity market
capitalizations. Currently, these four countries are Japan, the United Kingdom,
the United States and Germany. At December 31, 1997, those countries' equity
market capitalizations totalled approximately [ ]% of the world's equity market
capitalization according to data provided by Morgan Stanley Capital
International. The Fund will at all times, except during defensive periods,
maintain investments in at least three countries having smaller capital markets.

      The Developing Capital Markets Focus Fund seeks to benefit from economic
and other developments in smaller capital markets. The investment objective of
the Fund reflects the belief that investment opportunities may result from an
evolving long-term international trend favoring more market-oriented economies,
a trend that may especially benefit certain countries having smaller capital
markets. This trend may be facilitated by local or international political,
economic or financial developments that could benefit the capital markets of
such countries. Certain such countries, particularly so-called "emerging"
countries (such as Malaysia, Mexico and Thailand) which may be in the process of
developing more market-oriented economies, may experience relatively high rates
of economic growth. Other countries (such as France, the Netherlands and Spain),
although having relatively mature smaller capital markets, may also be in a
position to benefit from local or international developments encouraging greater
market orientation and diminishing governmental intervention in economic
affairs.

      Many investors, particularly individuals, lack the information, capability
or inclination to invest in countries having smaller capital markets. It also
may not be permissible for such investors to invest directly in certain such
markets. Unlike many intermediary investment vehicles, such as closed-end
investment companies that invest in a single country, the Fund intends to
diversify investment risk among the capital markets of a number of countries.
The Fund will not necessarily seek to diversify investments on a geographical
basis or on the basis of the level of economic development of any particular
country.

      In its investment decision-making, Merrill Lynch Asset Management, L.P.
(the "Investment Adviser") will emphasize the allocation of assets among certain
countries' capital markets, rather than the selection of particular industries
or issuers. Because of the general illiquidity of the capital markets in some
countries, the Fund may invest in a relatively small number of leading or
actively traded companies in a country's capital markets in the expectation that
the investment experience of the securities of such companies will substantially
represent the investment experience of the country's capital markets as a whole.

      The Developing Capital Markets Focus Fund also may invest in debt
securities of issuers in countries having smaller capital markets. Capital
appreciation in debt securities may arise as a result of a favorable change in
relative foreign exchange rates, in relative interest rate levels, or in the
creditworthiness of issuers. In accordance with its investment objective, the
Fund will not seek to benefit from anticipated short-term fluctuations in
currency exchange rates. The Fund may, from time to time, invest in debt
securities with relatively high yields (as compared to other debt securities
meeting the Fund's investment criteria), notwithstanding that the Fund may not
anticipate


                                        4
<PAGE>   181

that such securities will experience substantial capital appreciation. See
"Other Investments and Risks" below. Such income can be used, however, to offset
the operating expenses of the Fund.

      The Developing Capital Markets Focus Fund may invest in debt securities
issued or guaranteed by foreign governments (including foreign states, provinces
and municipalities) or their agencies and instrumentalities ("governmental
entities"), issued or guaranteed by international organizations designated or
supported by multiple foreign governmental entities (which are not obligations
of foreign governments) to promote economic reconstruction or development
("supranational entities"), or issued by foreign corporations or financial
institutions.

      Supranational entities include international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Steel and Coal Community, the Asian
Development Bank and the Inter-American Development Bank. The governmental
members, or "stockholders," usually make initial capital contributions to the
supranational entity and in many cases are committed to make additional capital
contributions if the supranational entity is unable to repay its borrowings.

      For purposes of the Developing Capital Markets Focus Fund's investment
objective, an issuer ordinarily will be considered to be located in the country
where the primary trading market of its securities is located. The Fund,
however, may consider a company to be located in countries having smaller
capital markets, without reference to its domicile or to the primary trading
market of its securities, when at least 50% of its non-current assets,
capitalization, gross revenues or profits in any one of the two most recent
fiscal years represents (directly or indirectly through subsidiaries) assets or
activities located in such countries. The Fund also may consider closed-end
investment companies to be located in the country or countries in which they
primarily make their portfolio investments.

      The Developing Capital Markets Focus Fund may invest a significant portion
of its assets in securities of foreign issuers in smaller capital markets.
Foreign investments involve risks, which are often heightened for investments in
smaller capital markets, including fluctuations in foreign exchange rates,
future political and economic developments, different legal systems and the
existence or possible imposition of exchange controls or other foreign or United
States governmental laws or restrictions applicable to such investments. With
respect to certain countries, there may be the possibility of expropriation of
assets, confiscatory taxation, high rates of inflation, political or social
instability or diplomatic developments which could affect investment in those
countries. In addition, certain foreign investments may be subject to foreign
withholding taxes. See "Other Investments and Risks" below.

      There may be less publicly available information about an issuer in a
smaller capital market than would be available about a United States company,
and it may not be subject to accounting, auditing and financial reporting
standards and requirements comparable to those of United States companies. As a
result, traditional investment measurements, such as price/earnings ratios, as
used in the United States, may not be applicable in certain capital markets.
Furthermore, smaller capital markets have substantially less volume than United
States markets so securities in many smaller capital markets are less liquid and
their prices may be more volatile than securities of comparable United States
companies. See "Other Portfolio Strategies -- Foreign Securities" in the
Appendix to this Prospectus.

Other Investments and Risks

      In addition, the Fund may purchase certain securities that are not
registered under the Securities Act of 1933, as amended and which therefore may
be subject to restrictions on their transfer or resale.

      The Developing Capital Markets Focus Fund has established no rating
criteria for the debt securities in which it may invest, and such securities may
not be rated at all for creditworthiness. Securities rated in the medium to
lower rating categories of nationally recognized statistical rating
organizations and unrated securities of comparable quality are predominantly
speculative with respect to the capacity to pay interest and repay principal


                                        5
<PAGE>   182

in accordance with the terms of the security and generally involve a greater
volatility of price than securities in higher rating categories. In purchasing
such securities, the Fund will rely on the Investment Adviser's judgment,
analysis and experience in evaluating the creditworthiness of an issuer of such
securities. The Investment Adviser will take into consideration, among other
things, the issuer's financial resources, its sensitivity to economic conditions
and trends, its operating history, the quality of the issuer's management and
regulatory matters. The Fund does not intend to purchase debt securities that
are in default or which the Investment Adviser believes will be in default. See
"Risks of High Yield Securities" in the Appendix to this Prospectus.

      The Developing Capital Markets Focus Fund invests in securities of foreign
issuers. Investments in foreign securities, particularly those of
non-governmental issuers, involve considerations and risks that are not
ordinarily associated with investing in domestic issuers. These considerations
and risks include changes in currency rates, currency exchange control
regulations, the possibility of expropriation, confiscatory taxation, high rates
of inflation, the unavailability of financial information or the difficulty of
interpreting financial information prepared under foreign accounting standards,
less liquidity and more volatility in foreign securities markets, the impact of
political, social or diplomatic developments, and the difficulty of assessing
economic trends in foreign countries. In addition, net investment income earned
by the Fund on a foreign security may be subject to withholding and other taxes
imposed by foreign governments, which will reduce the Fund's net investment
income. The Fund may from time to time be substantially invested in
non-dollar-denominated securities of foreign issuers. Changes in foreign
currency exchange rates may affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. See "Other Portfolio Strategies --Foreign Securities" in the
Appendix to this Prospectus.

      The Developing Capital Markets Focus Fund may engage in transactions, such
as currency swaps and purchasing and selling options on currencies, for purposes
of hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the US dollar. Although such instruments will
be used with the intention of hedging against adverse currency movements,
transactions in such instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the Fund's hedging
strategies will be ineffective and may cause the Fund to realize losses.

      The Developing Capital Markets Focus Fund may from time to time enter into
standby commitment agreements and is authorized to write (i.e., sell) and
purchase call and put options on securities held in its portfolio or securities
indices the performance of which is substantially correlated with securities
held in its portfolio, may engage in transactions in futures and may invest in
securities the potential return of which is based on the change in particular
measurements of value or rate (i.e., indexed and inverse securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed and inverse securities,
options, futures and foreign exchange transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Government Bond Fund is to seek the
highest possible current income consistent with the protection of capital
afforded by investing in debt securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities. Under normal circumstances, all
or substantially all of the Fund's assets will be invested in such securities.
Depending on market conditions, an average maturity of six to fifteen years is
anticipated. When, in the opinion of management, prevailing market or economic
conditions warrant, a portion of the Fund may be invested in money market
securities or a liquid asset fund to effectively utilize cash reserves. There
can be no assurance that the Government Bond Fund will achieve its investment
objective.

      Certain of the securities in which the Government Bond Fund invests are
supported by the full faith and credit of the U.S. Government, such as U.S.
Treasury obligations. Other of the securities in which the Fund invests are not
supported by the full faith and credit of the U.S. Government but are issued by
U.S. Government agencies, instrumentalities or government-sponsored enterprises.
Such securities are generally supported only by the credit of the agency,
instrumentality or enterprise issuing the security and are generally considered
to have a low principal risk. However, because of the longer-term maturities of
the securities in which the Fund will invest, interest rate fluctuations may
adversely affect the market value of such securities. As interest rates rise,
the value of fixed-income securities will fall, adversely affecting the net
asset value of the Fund. The Fund should be considered a long-term investment
and a vehicle for diversification, and not as a balanced investment program. The
Fund may not be appropriate as the exclusive investment to fund a variable
annuity or variable life insurance contract ("Contract") for all Contract
owners.

      The U.S. Treasury Department has enacted regulations prescribing
diversification standards to be met by investment company portfolios to which
the investment base for any variable annuity policy has been allocated as a
condition to such policies being treated as variable annuity contracts under the
Internal Revenue Code of 1986, as amended. The regulations limit the percentage
of the total assets of any investment company portfolio which may be invested in
securities of any five or fewer issuers, including a requirement that no more
than 55% of a portfolio's total assets be invested in the securities of any one
issuer. Direct obligations of the U.S. Treasury are not excepted from the
diversification requirements. Each government agency or instrumentality issuing,
guaranteeing or insuring securities will be treated as a separate issuer for
purposes of the diversification standards.

      In addition, the Government Bond Fund may purchase certain securities that
are not registered under the Securities Act of 1933, as amended and which
therefore may be subject to restrictions on their transfer or resale. The Fund
may also invest in securities the potential return of which is based on the
change in particular measurements of value or rate (i.e., indexed securities). A
further discussion of the investments described in this paragraph and the risks
associated with such investments is set forth in the Appendix to this
Prospectus, including Annex B of the Appendix to this Prospectus, which includes
a discussion of certain portfolio strategies relating to indexed securities.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Index 500 Fund is to seek to provide
investment results that, before expenses, correspond to the aggregate price and
yield performance of the S&P 500 Index. There can be no assurance that the Fund
will achieve its investment objective. The Fund should be considered a long-term
investment and a vehicle for diversification, and not as a balanced investment
program. The Fund may not be appropriate as the exclusive investment to fund a
variable annuity or variable life insurance contract ("Contract") for all
Contract owners.

      The S&P 500 Index is a market-weighted index composed of 500 common stocks
issued by companies in a wide range of businesses and which collectively
represent a substantial portion of all common stocks publicly traded in the U.S.
The composition of the S&P 500 Index is determined by Standard & Poor's Rating
Group ("Standard & Poor's"), a division of the McGraw-Hill Companies, Inc.
Standard & Poor's criteria for selecting common stocks to include in the S&P 500
Index is based on factors such as market capitalization, trading activity and
the adequacy of representation of particular industries, and favors U.S.-traded
stocks of large companies that are among the most dominant in their industries.
The S&P 500 Index is generally considered broadly representative of the
performance of large-capitalization publicly traded common stocks in the U.S.
The inclusion of a stock in the S&P 500 Index does not imply that Standard &
Poor's believes the stock to be an attractive investment.

      The Index 500 Fund will not attempt to buy or sell securities based on
Merrill Lynch Asset Management, L.P.'s (the "Investment Adviser") economic,
financial or market analysis, but will instead employ a "passive" approach that
attempts to remain invested at all times in a portfolio of assets the
performance of which is expected to be strongly correlated with that of the S&P
500 Index. The Index 500 Fund may invest in all 500 stocks in the S&P 500 Index
in approximately the same proportions as their weightings in the S&P 500 Index,
or may invest in a statistically selected sample of the 500 stocks which
comprise the S&P 500 Index designed, based on market capitalizations, industry
weightings and financial attributes, to have aggregate investment
characteristics similar to those of the S&P 500 Index as a whole. The Index 500
Fund may also (i) purchase common stocks not included in the S&P 500 Index as a
proxy for certain common stocks included in the S&P 500 Index when the
Investment Adviser believes it is an efficient means of replicating the
performance of that index to do so, and (ii) invest in options and future
contracts linked to the performance of the S&P 500 Index or of common stocks
represented in the index.

      Under normal circumstances, it is expected that the Index 500 Fund will
invest at least 90% (65% if the Index 500 Fund's assets are below $20 million)
of its assets in common stocks represented in the S&P 500 Index and related
options and futures contracts. The Index 500 Fund may invest a substantial
portion of its assets in options and futures contracts in order to gain market
exposure efficiently in the event of subscriptions, to maintain liquidity in the
event of redemptions and to minimize trading costs. The Index 500 Fund may also
invest in short-term fixed income instruments as cash reserves. The Index 500
Fund will not invest in short-term fixed income instruments, options or futures
contracts for the purpose of implementing a defensive market strategy by
lowering the Fund's exposure to common stocks to protect against a potential
stock market decline, but instead will attempt to remain fully invested without
regard to the Investment Adviser's market analysis. The Fund may, however, hold
short-term fixed income instruments for temporary cash management purposes.

      The foregoing investment techniques are expected to be an effective means
of substantially duplicating the aggregate price and yield performance of the
S&P 500 Index at such times when the Index 500 Fund is not fully invested in all
500 stocks in the S&P 500 Index in approximately the same proportions as their
weightings in that index. To the extent the Index 500 Fund utilizes the
foregoing investment techniques, the Fund may not track the S&P 500 Index with
the same degree of accuracy as the Fund would if it were fully invested in all
500 stocks in the S&P 500 Index in approximately the same proportions as their
weightings in that index. However, the principal advantage of the foregoing
investment techniques is to provide an efficient means to invest in the universe
of stocks of the S&P 500 Index. The Fund is expected to provide broad
diversification, and will seek to operate at low costs due to its "passive"
approach to portfolio management and anticipated low portfolio turnover rate.

      In addition, the Index 500 Fund may purchase certain securities that are
not registered under the Securities Act of 1933, as amended and which therefore
may be subject to restrictions on their transfer or resale. The Index 500 Fund
may also invest in securities of foreign issuers to the extent such issuers are
included in the S&P 500 Index. See "Other Portfolio Strategies--Foreign
Securities" in the Appendix to this Prospectus. The Fund is also authorized to
write (i.e., sell) and purchase call and put options on securities held in its
portfolio or securities indices the performance of which is substantially
correlated with securities held in its portfolio and may engage in transactions
in futures and may invest in securities the potential return of which is based
on the change in particular measurements of value or rate (i.e., indexed
securities). A further discussion of the investments described in this paragraph
and the risks associated with such investments is set forth in the Appendix to
this Prospectus, including Annex B of the Appendix to this Prospectus which
includes a discussion of certain portfolio strategies relating to indexed
securities, options and futures.

                        INVESTMENT OBJECTIVE AND POLICIES

      The investment objective of the Global Growth Focus Fund is to seek
long-term growth of capital. The Global Growth Focus Fund will seek to achieve
its investment objective by investing in a diversified portfolio of equity
securities of issuers located in various foreign countries and the United
States, placing particular emphasis on companies that have exhibited
above-average growth rates in earnings. The Fund may be appropriate only for
long-term investors who can assume the risk of loss of principal, and do not
seek current income. There can be no assurance that the Global Growth Focus Fund
will achieve its investment objective. The Global Growth Focus Fund may employ a
variety of techniques, including derivative investments, in connection with
certain trading strategies, including to hedge against market and currency risk,
to enhance total return or to gain exposure to equity markets. See Annex B of
the Appendix to this Prospectus. Investments on an international basis in
foreign securities markets involve risks and special considerations not
typically associated with investments in securities of United States issuers.
See "Other Investments and Risks" below. The Fund should be considered a
long-term investment and a vehicle for diversification, and not as a balanced
investment program.

      Issuers may achieve above-average growth rates in earnings from a variety
of factors including, but not limited to, above-average growth rates in sales,
profit margin improvement, proprietary or niche products or services, leading
market shares, and underlying strong industry growth. Management of the Fund
believes that companies which possess above-average earnings growth frequently
provide the prospect of above-average stock market returns, although such
companies tend to have higher relative stock market valuations. Emphasis also
will be given to companies having medium to large stock market capitalizations
($2 billion or more). Investment in companies with lower market capitalizations,
especially those under $1 billion, may involve special risks including limited
product lines, market or financial resources or a limited management group. In
addition, many smaller company stocks trade less frequently and in smaller
volume, and may be subject to more abrupt or erratic price movements or may be
more sensitive to market fluctuations, than stocks of larger companies.

      The Global Growth Focus Fund will emphasize investments in equity
securities, primarily common stock, and, to a lesser extent, securities
convertible into common stock, preferred stock, rights to subscribe for common
stock and other investments the return on which is determined by the performance
of a common stock or a basket or index of common stocks. Under normal market
conditions, at least 65% of the Fund's total assets will be invested in equity
securities of issuers from at least three different countries. The Fund reserves
the right, as a defensive measure and to provide for redemptions, to hold other
types of securities, including non-convertible preferred stocks and debt
securities rated investment grade by a nationally recognized statistical rating
organization, U.S. Government and money market securities, including repurchase
agreements, or cash, in such proportions, including up to 100%, as in the
opinion of Merrill Lynch Asset Management L.P. (the "Investment Adviser")
prevailing market or economic conditions warrant.

Other Investments and Risks

      In addition, the Global Growth Focus Fund may purchase certain securities
that are not registered under the Securities Act of 1933, as amended, and which
therefore may be subject to restrictions on their transfer or resale.

      Because a substantial portion of the Fund's assets may be invested in
securities of non-U.S. issuers, an investor in the Fund should be aware of
certain risk factors and special considerations relating to international
investing, which may involve risks that are not typically associated with
investments in the securities of U.S. issuers. Investing on an international
basis involves certain risks not involved in domestic investments, including
fluctuations in foreign exchange rates, future political and economic
developments, different legal systems and the possible imposition of exchange
controls or other foreign governmental laws or restrictions. Securities prices
in different countries are subject to different economic, financial, political
and social factors. Since the Fund invests heavily in securities denominated or
quoted in currencies other than the U.S. dollar, changes in foreign currency
exchange rates will affect the value of securities in the Fund and the
unrealized appreciation or depreciation of investments. Currencies of certain
countries may be volatile and therefore may affect the value of securities
denominated in such


                                        3
<PAGE>   193

currencies. In addition, with respect to certain foreign countries, there is the
possibility of expropriation of assets, confiscatory taxation, difficulty in
obtaining or enforcing a court judgment, economic, political or social
instability or diplomatic developments that could affect investments in those
countries. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross domestic
product, rates of inflation, capital reinvestment, resources, self-sufficiency
and balance of payments position. Certain foreign investments also may be
subject to foreign withholding taxes, These risks often are heightened for
investments in smaller, emerging capital markets. For additional information
concerning the risks of investing in foreign securities. See "Other Portfolio
Strategies--Foreign Securities" in the Appendix to this Prospectus.

      The Global Growth Focus Fund may also engage in transactions, such as
currency swaps and purchasing and selling options on currencies, for purposes of
hedging against the decline in the value of currencies in which its portfolio
holdings are denominated against the U.S. dollar. The Fund is also authorized to
write (i.e., sell) and purchase both call and put options on securities held in
its portfolio, securities indices the performance of which is substantially
correlated with securities held in its portfolio or on securities it intends to
purchase and may also invest in futures and in securities the potential return
of which is based on the change in particular measurements of value or rate
(i.e., indexed securities).

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix to this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to indexed securities, options, futures
and foreign exchange transactions.

                        INVESTMENT OBJECTIVE AND POLICIES

      The Capital Focus Fund's investment objective is to achieve the highest
total investment return consistent with prudent risk. To do this, management of
the Fund shifts the emphasis among equity, debt (including money market) and
convertible securities. This flexible, total investment return approach is
called a "fully managed" investment policy. It distinguishes the Capital Focus
Fund from other investment companies, which often seek either capital growth or
current income. This approach permits management of the Fund to vary investment
policy based on its evaluation of changes in economic and market trends. Total
investment return is the aggregate of income and capital value changes.
Consistent with this policy, the Capital Focus Fund's portfolio may, at any
given time, be invested substantially in equity securities, corporate bonds or
money market securities. It is the expectation of management that, over longer
periods, a major portion of the Fund's portfolio will consist of equity
securities of larger market capitalization, quality companies. There can be no
assurance that the Fund will achieve its investment objective. The Capital Focus
Fund may employ a variety of investments and techniques to hedge against market
and currency risk. See Annex B to the Appendix to this Prospectus.

      The Capital Focus Fund's investment philosophy is based on the belief
that, as in the past, the structure of the United States' economy and the
economies and securities markets of other countries will undergo continuous
change. Thus, the fully managed approach puts maximum emphasis on investment
flexibility. The two principal features of the Fund's management approach are
flexibility and concentration in "quality" companies.

      Flexibility. The Capital Focus Fund's fully managed investment approach
makes use of equity, debt (including money market) and convertible securities.
Freedom to move among these different types of securities as prevailing trends
change is the keystone of the Fund's investment policy.

      Concentration in "Quality" Companies. The earnings of quality companies
generally tend to grow consistently. Their internal strengths--good financial
resources, a strong balance sheet, satisfactory rate of return on capital, a
good industry position and superior management skills--give the Fund confidence
that these companies consistently will perform at high levels. The Fund
considers quality companies to be those that conform most closely to these
characteristics. Most of the Fund's equity portfolio is in the common stocks of
these quality companies.

      Sometimes, to reduce risk and to achieve the highest total investment
return, the Capital Focus Fund may invest in other securities:

      o Non-convertible, long-term debt securities, including "deep discount"
corporate debt securities, mortgage-backed securities issued or guaranteed by
governmental entities or private issuers, and debt securities issued or
guaranteed by governments, their agencies and instrumentalities. Such debt
securities generally will be "investment grade." However, the Fund has
established no rating criteria for the debt securities in which it may invest,
and the Fund may invest in securities that are rated below Baa by Moody's
Investors Service, Inc. ("Moody's") or below BBB by Standard & Poor's Ratings
Services ("S&P") or which, in the judgment of Merrill Lynch Asset Management,
L.P. (the "Investment Adviser") possess similar credit characteristics. Such
securities, sometimes referred to as "high yield/high risk securities" or "junk
bonds", are predominantly speculative with respect to the capacity to pay
interest and repay principal in accordance with the terms of the security and
generally involve a greater volatility of price than securities in higher rating
categories. See "Other Investment and Risks" below and "Risks of High Yield
Securities" in the Appendix to this Prospectus. The Fund does not intend to
purchase debt securities that are in default or which the Investment Adviser
believes will be in default. The Fund does not intend to invest in excess of 35%
of its total assets in securities that are rated below Baa by Moody's or below
BBB by S&P or that the Investment Adviser believes have characteristics similar
to those securities.

      o Convertible securities, i.e., fixed income issues that give the owner
the option of a later exchange for common stock. Convertible securities entitle
the holder to receive interest payments paid on corporate debt securities or the
dividend preference on a preferred stock until such time as the convertible
security matures or is redeemed or until the holder elects to exercise the
conversion privilege. The value of convertible securities is


                                        3
<PAGE>   197

influenced by both the yield of nonconvertible securities of comparable issuers
and by the value of the underlying common stock. The value of a convertible
security viewed without regard to its conversion feature (i.e., strictly on the
basis of its yield) is sometimes referred to as its "investment value." To the
extent interest rates change, the investment value of the convertible security
typically will fluctuate. However, at the same time, the value of the
convertible security will be influenced by its "conversion value," which is the
market value of the underlying common stock that would be obtained if the
convertible security were converted. Conversion value fluctuates directly with
the price of the underlying common stock. If, because of a low price for the
common stock, the conversion value is substantially below the investment value
of the convertible security, the price of the convertible security will be
governed principally by its investment value.

      o Cash or money-market securities to produce interest income during
periods of defensive investment.

      The Investment Adviser expects that over longer periods a larger portion
of the Fund's portfolio will consist of equity securities. However, the flexible
fully managed investment approach enables the Fund to switch its emphasis to
debt and convertible securities if, in the opinion of the Investment Adviser,
prevailing market or economic conditions warrant. The Investment Adviser will
determine the emphasis among equity and debt securities, including convertible
securities, based on its evaluation as to the types of securities presently
providing the opportunity for the highest total investment return consistent
with prudent risk.

Other Investments and Risks

      In addition, the Capital Focus Fund may purchase securities that are not
registered under the Securities Act of 1933, as amended, and which therefore may
be subject to restrictions on their transfer or resale.

      The Capital Focus Fund may invest up to 25% of its total assets in
securities of foreign issuers. Investments in securities of foreign issuers
involve certain risks, including fluctuations in foreign exchange rates, future
political and economic developments, and the possible imposition of exchange
controls or other foreign governmental laws or restrictions. In addition,
foreign companies may not be subject to accounting, auditing and financial
reporting standards and requirements comparable to those of U.S. companies. The
foreign markets also have different clearance and settlement procedures, and in
certain markets there have been times when settlements have been unable to keep
pace with the volume of securities transactions, making it difficult to conduct
such transactions. Delays in settlement could result in temporary periods when
assets of the Fund are uninvested and no return is earned thereon. The inability
of the Fund to make intended security purchases due to settlement problems could
cause the Fund to miss attractive investment opportunities. Inability to dispose
of a portfolio security due to settlement problems could result either in losses
to the Fund due to subsequent declines in the value of such portfolio security
or, if the Fund has entered into a contract to sell the security, could result
in possible liability to the purchaser. To the extent such investments are
subject to withholding or other taxes or to regulations relating to repatriation
of assets, the Fund's distributable income will be reduced. The prices of
securities in different countries may be subject to different economic,
financial, political and social factors.

      The Capital Focus Fund may from time to time be invested in
non-dollar-denominated securities of foreign issuers. Changes in foreign
currency exchange rates may affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned. Furthermore, the Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign currency rates during the period in which the Fund holds such
investments. See "Other Portfolio Strategies --Foreign Securities" in the
Appendix to this Prospectus.

      The Capital Focus Fund has established no rating criteria for the debt
securities in which it may invest, and such securities may not be rated at all
for creditworthiness. Securities rated in the medium to lower rating categories
of nationally recognized statistical rating organizations and unrated securities
of comparable quality are predominantly speculative with respect to the capacity
to pay interest and repay principal in accordance with the terms of the security
and generally involve a greater volatility of price than securities in higher
rating categories. In purchasing such securities, the Fund will rely on the
Investment Adviser's judgment, analysis and experience in evaluating the
creditworthiness of an issuer of such securities. The Investment Adviser will
take into consideration,


                                        4
<PAGE>   198

among other things, the issuer's financial resources, its sensitivity to
economic conditions and trends, its operating history, the quality of the
issuer's management and regulatory matters. The Fund does not intend to purchase
debt securities that are in default or that the Investment Adviser believes will
be in default. See "Risks of High Yield Securities" in the Appendix to this
Prospectus.

      Among the risks to which an investment in the Capital Focus Fund is
subject are interest rate risk and credit risk. Interest rate risk is the risk
that the portion of the Fund's net asset value attributable to the Fund's
fixed-income securities may fall when interest rates rise and rise when interest
rates fall. In general, fixed-income securities with longer maturities will be
subject to greater volatility resulting from interest rate fluctuations than
will fixed-income securities with shorter maturities. Credit risk is the risk
that an issuer of fixed-income securities that the Fund owns will not make
timely payments of interest or repayments of principal from the issuer. Credit
risk is generally greater in lower-rated securities.

      The Capital Focus Fund may invest in the securities of smaller or emerging
growth companies. The securities of smaller or emerging growth companies may be
subject to more abrupt or erratic market movements than larger, more established
companies or the market average in general. These companies may have limited
product lines, markets or financial resources, or they may be dependent on a
limited management group.

      The Capital Focus Fund may engage in transactions, such as currency swaps
and purchasing and selling options on currencies, for purposes of hedging
against the decline in the value of currencies in which its portfolio holdings
are denominated against the US dollar. Although such instruments will be used
with the intention of hedging against adverse currency movements, transactions
in such instruments involve the risk that anticipated currency movements will
not be accurately predicted and that the Fund's hedging strategies will be
ineffective and may cause the Fund to realize losses.

      The Capital Focus Fund may from time to time write (i.e. sell) covered
call options on its portfolio securities.

      A further discussion of the foregoing investments and the risks associated
with such investments is set forth in the Appendix of this Prospectus, including
Annex B of the Appendix to this Prospectus, which includes a discussion of
certain portfolio strategies relating to options and foreign exchange
transactions.

                             THE INSURANCE COMPANIES

      Shares of the Funds currently are sold to separate accounts ("Separate
Accounts") of Merrill Lynch Life Insurance Company ("MLLIC") and ML Life
Insurance Company of New York ("ML of New York"), as well as other insurance
companies not affiliated with MLLIC or ML of New York (together with MLLIC and
ML of New York, "Insurance Companies") to fund certain variable life insurance
contracts and/or variable annuities (together, "Contracts") issued by such
companies. The rights of the Insurance Companies as shareholders should be
distinguished from the rights of a Contract owner, which are set forth in the
Contract. A Contract owner has no interest in the shares of a Fund, but only in
the Contract. The Contract is described in the prospectus for each Contract.
That prospectus describes the relationship between increases or decreases in the
net asset value of shares of a Fund, and any distributions on such shares, and
the benefits provided under a Contract. The prospectus for the Contracts also
describes various fees payable to the Insurance Companies and charges to the
Separate Accounts made by the Insurance Companies with respect to the Contracts.
Since shares of the Funds will be sold only to the Insurance Companies for the
Separate Accounts, the terms "shareholder" and "shareholders" in this Prospectus
refer to the Insurance Companies. MLLIC and ML of New York are wholly owned
subsidiaries of ML&Co., as is the Investment Adviser.

                 INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS

Investment Objectives

      Each Fund of the Company has a different investment objective, which it
pursues through separate investment policies as described in the Fund's
Prospectus (of which this Appendix is a part). The differences in objectives and
policies among the Funds can be expected to affect the return of each Fund and
the degree of market and financial risk to which each Fund is subject. Each Fund
is classified as "diversified," as defined in the Investment Company Act of
1940, as amended (the "Investment Company Act" or the "Act") except for the
Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the Global
Strategy Focus Fund, the Index 500 Fund, and the Natural Resources Focus Fund,
each of which is classified as "non-diversified." The investment objectives and
classification of each Fund may not be changed without the approval of the
holders of a majority of the outstanding shares of each Fund affected.

      Fixed Income Security Ratings. No Fund other than the Developing Capital
Markets Focus Fund, the High Current Income Fund, the Capital Focus Fund and the
International Equity Focus Fund invests in fixed-income securities rated below
investment grade (i.e., securities rated Ba or below by Moody's Investors
Service, Inc. ("Moody's") or BB or below by Standard & Poor's Ratings Group
("Standard & Poor's") at the time of investment). However, securities purchased
by a Fund may subsequently be downgraded. Such securities may continue to be
held and will be sold only if, in the judgment of the Investment Adviser, it is
advantageous to do so. Securities in the lowest category of investment grade
debt securities may have speculative characteristics, which may lead to weakened
capacity to pay interest and principal during periods of adverse economic
conditions. See Annex A of this Appendix for a fuller description of corporate
bond ratings.

Non-Diversified Funds

      The Developing Capital Markets Focus, Global Bond Focus, Global Strategy
Focus, Index 500, and Natural Resources Focus Funds are classified as
non-diversified investment companies under the Investment Company Act. However,
each Fund will have to limit its investments to the extent required by the
diversification requirements applicable to regulated investment companies under
the Internal Revenue Code of 1986, as amended (the "Code" or the "Internal
Revenue Code"). To qualify as a regulated investment company, a Fund, at the
close of each fiscal quarter, may not have more than 25% of its total assets
invested in the securities (except obligations of the U.S. Government, its
agencies or instrumentalities) of any one issuer and with respect to 50% of its
assets, (i) may not have more than 5% of its total assets invested in the
securities of any one issuer and (ii) may not own more than 10% of the
outstanding voting securities of any one issuer.


                                       A-1
<PAGE>   201

Investment Restrictions

      The Company has adopted a number of restrictions and policies relating to
the investment of its assets and its activities which are fundamental policies
and may not be changed without the approval of the holders of the Company's
outstanding voting securities (including a majority of the shares of each Fund).
Investors are referred to the Statement of Additional Information for a complete
description of such restrictions and policies.

Other Portfolio Strategies

      Restricted Securities. Each of the Funds is subject to limitations on the
amount of illiquid securities it may purchase; however, each Fund may purchase
without regard to that limitation certain securities that are not registered
under the Securities Act of 1933, as amended (the "Securities Act"), including
(a) commercial paper exempt from registration under Section 4(2) of the
Securities Act, and (b) securities that can be offered and sold to "qualified
institutional buyers" under Rule 144A under the Securities Act, provided that
the Company's Board of Directors continuously determines, based on the trading
markets for the specific Rule 144A security, that it is liquid. The Board of
Directors may adopt guidelines and delegate to the Investment Adviser the daily
function of determining and monitoring liquidity of restricted securities. The
Board has determined that securities sold under Rule 144A that are freely
tradeable in their primary market offshore should be deemed liquid. The Board,
however, will retain sufficient oversight and be ultimately responsible for the
determinations.

      Since it is not possible to predict with assurance exactly how the market
for restricted securities sold and offered under Rule 144A will develop, the
Board of Directors will carefully monitor the Funds' investments in these
securities, focusing on such factors, among others, as valuation, liquidity and
availability of information. This investment practice could have the effect of
increasing the level of illiquidity in a Fund to the extent that qualified
institutional buyers become for a time uninterested in purchasing these
restricted securities.

      Foreign Securities. The Basic Value Focus, Developing Capital Markets
Focus, Special Value Focus, Global Strategy Focus, Global Bond Focus, Global
Utility Focus, High Current Income, International Equity Focus, Natural
Resources Focus, Prime Bond, Quality Equity, Global Growth Focus, Capital Focus
and Reserve Assets Funds may invest in securities of foreign issuers. The Index
500 Fund may also invest in securities of foreign issuers to the extent such
issuers are included in the Standard & Poor's 500 Composite Stock Price Index
(the "S&P Index"). Investments in foreign securities, particularly those of
non-governmental issuers, involve considerations and risks which are not
ordinarily associated with investing in domestic issuers. These considerations
and risks include changes in currency rates, currency exchange control
regulations, the possibility of expropriation, the unavailability of financial
information or the difficulty of interpreting financial information prepared
under foreign accounting standards, less liquidity and more volatility in
foreign securities markets, the impact of economic, political, social or
diplomatic developments, and the difficulty of assessing economic trends in
foreign countries. Foreign legal systems may differ from the U.S. legal system,
and if it should become necessary, a Fund could encounter greater difficulties
in invoking legal processes abroad than would be the case in the United States.
Transaction costs in foreign securities may be higher. The operating expense
ratio of a Fund investing in foreign securities can be expected to be higher
than that of an investment company investing exclusively in United States
securities because the expenses of the Fund, such as custodial costs, are
higher. In addition, net investment income earned by a Fund on a foreign
security may be subject to withholding and other taxes imposed by foreign
governments which will reduce a Fund's net investment income. The Investment
Adviser will consider these and other factors before investing in foreign
securities, and will not make such investments unless, in its opinion, such
investments will meet the standards and objectives of a particular Fund. No Fund
that may invest in foreign securities, other than the Natural Resources Focus
and Global Strategy Focus Funds, will concentrate its investments in any
particular country. The Developing Capital Markets Focus, Global Bond Focus,
Global Strategy Focus, Global Utility Focus, International Equity Focus, Global
Growth Focus Fund and Natural Resources Focus Funds may from time to time be
substantially invested in non-dollar-denominated securities of foreign issuers.
For a Fund that invests in foreign securities denominated or quoted in
currencies other than the United States dollar, changes in foreign currency
exchange rates may directly affect the value of securities in the portfolio and
the unrealized appreciation or depreciation of investments insofar as United
States investors are concerned, and a Fund's return on investments in
non-dollar-denominated securities may be reduced or enhanced as a result of
changes in foreign


                                       A-2
<PAGE>   202

currency rates during the period in which the Fund holds such investments.
Foreign currency exchange rates are determined by forces of supply and demand in
the foreign exchange markets. These forces are, in turn, affected by
international balance of payments and other economic and financial conditions,
government intervention, speculation and other factors. With respect to certain
countries, there may be the possibility of expropriation of assets, confiscatory
taxation, high rates of inflation, political or social instability or diplomatic
developments which could affect investment in those countries. Each Fund of the
Company other than the Developing Capital Markets Focus, Global Bond Focus,
Global Strategy Focus, Global Utility Focus, International Equity Focus, Natural
Resources Focus, Global Growth Focus, Capital Focus Fund and Quality Equity
Funds will purchase only securities issued in dollar denominations.

      The securities markets of many countries at times in the past have moved
relatively independently of one another due to different economic, financial,
political and social factors. When such lack of correlation, or negative
correlation, in movements of these securities markets occurs, it may reduce risk
for a Fund's portfolio as a whole. This negative correlation also may offset
unrealized gains a Fund has derived from movements in a particular market. To
the extent the various markets move independently, total portfolio volatility is
reduced when the various markets are combined into a single portfolio. Of
course, movements in the various securities markets may be offset by changes in
foreign currency exchange rates. Exchange rates frequently move independently of
securities markets in a particular country. As a result, gains in a particular
securities market may be affected by changes in exchange rates.

      Each of the International Equity Focus Fund and Developing Capital Markets
Focus Fund may invest a significant portion of its assets in securities of
foreign issuers in smaller capital markets, while each of the other Funds which
is permitted to invest in foreign securities may from time to time invest in
securities of such foreign issuers. Foreign investments involve risks, including
fluctuations in foreign exchange rates, future political and economic
developments, different legal systems, the existence or possible imposition of
exchange controls, or other foreign or United States governmental laws or
restrictions, that are often heightened for investments in smaller capital
markets.

      There may be less publicly available information about an issuer in a
foreign market, particularly one in a smaller capital market, than would be
available about a United States company, and it may not be subject to
accounting, auditing and financial reporting standards and requirements
comparable to those of United States companies. As a result, traditional
investment measurements, such as price/earnings ratios, as used in the United
States, may not be applicable in certain capital markets.

      Smaller capital markets, while often growing in trading volume, have
substantially less volume than United States markets, and securities in many
smaller capital markets are less liquid and their prices may be more volatile
than securities of comparable United States companies. Brokerage commissions,
custodial services, and other costs relating to investment in smaller capital
markets are generally more expensive than in the United States. Such markets
have different clearance and settlement procedures, and in certain markets there
have been times when settlements have been unable to keep pace with the volume
of securities transactions, making it difficult to conduct such transactions.
Further, satisfactory custodial services for investment securities may not be
available in some countries having smaller capital markets, which may result in
a Fund which invests in these markets incurring additional costs and delays in
transporting and custodying such securities outside such countries. Delays in
settlement could result in temporary periods when assets of such a Fund are
uninvested and no return is earned thereon. The inability of a Fund to make
intended security purchases due to settlement problems could cause the Fund to
miss attractive investment opportunities. Inability to dispose of a portfolio
security due to settlement problems could result either in losses to the Fund
due to subsequent declines in value of the portfolio security or, if the Fund
has entered into a contract to sell the security, could result in possible
liability to the purchaser. There is generally less government supervision and
regulation of exchanges, brokers and issuers in countries having smaller capital
markets than there is in the United States.

      As a result, management of a Fund that invests in foreign securities may
determine that, notwithstanding otherwise favorable investment criteria, it may
not be practicable or appropriate to invest in a particular country.


                                       A-3
<PAGE>   203

A Fund may invest in countries in which foreign investors, including management
of the Fund, have had no or limited prior experience.

      Certain of the Funds may invest in debt securities issued by foreign
governments. Investments in foreign government debt securities, particularly
those of emerging market country governments, involve special risks. Certain
emerging market countries have historically experienced, and may continue to
experience, high rates of inflation, high interest rates, exchange rate
fluctuations, large amounts of external debt, balance of payments and trade
difficulties and extreme poverty and unemployment. The issuer or governmental
authority that controls the repayment of an emerging market country's debt may
not be able or willing to repay the principal and/or interest when due in
accordance with the terms of such debt. A debtor's willingness or ability to
repay principal and interest due in a timely manner may be affected by, among
other factors, its cash flow situation, and, in the case of a government debtor,
the extent of its foreign reserves, the availability of sufficient foreign
exchange on the date a payment is due, the relative size of the debt service
burden to the economy as a whole and the political constraints to which a
government debtor may be subject. Government debtors may default on their debt
and may also be dependent on expected disbursements from foreign governments,
multilateral agencies and others abroad to reduce principal and interest
arrearages on their debt. Holders of government debt, including the Fund, may be
requested to participate in the rescheduling of such debt and to extend further
loans to government debtors.

      As a result of the foregoing, a government obligor may default on its
obligations. If such an event occurs, a Fund may have limited legal recourse
against the issuer and/or guarantor. Remedies must, in some cases, be pursued in
the courts of the defaulting party itself, and the ability of the holder of
foreign government debt securities to obtain recourse may be subject to the
political climate in the relevant country. Government obligors in developing and
emerging market countries are among the world's largest debtors to commercial
banks, other governments, international financial organizations and other
financial institutions. Some issuers of the government debt securities in which
a Fund may invest have in the past experienced substantial difficulties in
servicing their external debt obligations, which led to defaults on certain
obligations and the restructuring of certain indebtedness. Restructuring
arrangements have included, among other things, reducing and rescheduling
interest and principal payments by negotiating new or amended credit agreements.

      The Global Utility Focus Fund, International Equity Focus Fund, Developing
Capital Markets Focus Fund, Capital Focus Fund and the Global Growth Focus Fund
may invest in the securities of foreign issuers in the form of American
Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") or other
securities convertible into securities of foreign issuers. These securities may
not necessarily be denominated in the same currency as the securities into which
they may be converted. ADRs are receipts typically issued by an American bank or
trust company which evidence ownership of underlying securities issued by a
foreign corporation. EDRs are receipts issued in Europe which evidence a similar
ownership arrangement. Generally, ADRs, which are issued in registered form, are
designated for use in the United States securities markets, and EDRs, which are
issued in bearer form, are designed for use in European securities markets. The
Funds may invest in ADRs and EDRs through both sponsored and unsponsored
arrangements. In a sponsored ADR or EDR arrangement, the foreign issuer assumes
the obligation to pay some or all of the depository's transaction fees, whereas
in an unsponsored arrangement the foreign issuer assumes no obligations and the
depository's transaction fees are paid by the ADR or EDR holders. Foreign
issuers in respect of whose securities unsponsored ADRs or EDRs have been issued
are not necessarily obligated to disclose material information in the markets in
which the unsponsored ADRs or EDRs are traded and, therefore, there may not be a
correlation between such information and the market value of such securities.

      The Developing Capital Markets Focus and International Equity Focus Funds
intend to invest in securities of foreign issuers in smaller capital markets.
Some countries with smaller capital markets prohibit or impose substantial
restrictions on investments in their capital markets, particularly their equity
markets, by foreign entities such as the Fund. As illustrations, certain
countries require governmental approval prior to investments by foreign persons,
or limit the amount of investment by foreign persons in a particular company, or
limit the investment by foreign persons to only a specific class of securities
of a company which may have less advantageous terms than securities of the
company available for purchase by nationals.


                                       A-4
<PAGE>   204

      A number of countries, such as South Korea, Taiwan and Thailand, have
authorized the formation of closed-end investment companies to facilitate
indirect foreign investment in their capital markets. In accordance with the
Investment Company Act, the Developing Capital Markets Focus, Global Growth
Focus and International Equity Focus Funds each may invest up to 10% of its
total assets in securities of such closed-end investment companies. This
restriction on investments in securities of closed-end investment companies may
limit opportunities for the Fund to invest indirectly in certain smaller capital
markets. Shares of certain closed-end investment companies may at times be
acquired only at market prices representing premiums to their net asset values.
If a Fund acquires shares in closed-end investment companies, shareholders would
bear both their proportionate share of expenses in the Fund (including
management and advisory fees) and, indirectly, the expenses of such closed-end
investment companies. A Fund also may seek, at its own cost, to create its own
investment entities under the laws of certain countries.

      In some countries, banks or other financial institutions may constitute a
substantial number of the leading companies or the companies with the most
actively traded securities. Also, the Investment Company Act restricts a Fund's
investments in any equity security of an issuer which, in its most recent fiscal
year, derived more than 15% of its revenues from "securities related
activities," as defined by the rules thereunder. These provisions may also
restrict a Fund's investments in certain foreign banks and other financial
institutions.

      Rules adopted under the Investment Company Act permit the Funds to
maintain their foreign securities and cash in the custody of certain eligible
non-U.S. banks and securities depositories. Certain banks in foreign countries
may not be eligible sub-custodians for the Funds, in which event the Funds may
be precluded from purchasing securities in certain foreign countries in which
they otherwise would invest or the Funds may incur additional costs and delays
in providing transportation and custody services for such securities outside of
such countries. The Funds may encounter difficulties in effecting on a timely
basis portfolio transactions with respect to any securities of issuers held
outside their countries. Other banks that are eligible foreign sub-custodians
may be recently organized or otherwise lack extensive operating experience. In
addition, in certain countries there may be legal restrictions or limitations on
the ability of the Funds to recover assets held in custody by foreign
sub-custodians in the event of the bankruptcy of the sub-custodian.

      Lending of Portfolio Securities. Each Fund of the Company may from time to
time lend securities (but not in excess of 20%, or in the case of the Global
Growth Focus Fund 33 1/3%) of its total assets from its portfolio to brokers,
dealers and financial institutions and receive collateral in cash or securities
issued or guaranteed by the U.S. Government which, while the loan is
outstanding, will be maintained at all times in an amount equal to at least 100%
of the current market value of the loaned securities plus accrued interest. Such
cash collateral will be invested in short-term securities, the income from which
will increase the return to the Fund.

      Forward Commitments. Each of the Funds may purchase securities on a
when-issued basis, and they may purchase or sell such securities for delayed
delivery. These transactions occur when securities are purchased or sold by a
Fund with payment and delivery taking place in the future to secure what is
considered an advantageous yield and price to the Fund at the time of entering
into the transaction. The value of the security on the delivery date may be more
or less than its purchase price. A Fund entering into such transactions will
maintain a segregated account with its custodian of cash or liquid securities in
an aggregate amount equal to the amount of its commitments in connection with
such delayed delivery and purchase transactions.

      Standby Commitment Agreements. The Developing Capital Markets Focus,
Global Utility Focus, Global Growth Focus and High Current Income Funds may from
time to time enter into standby commitment agreements. Such agreements commit
the respective Fund, for a stated period of time, to purchase a stated amount of
a fixed income security which may be issued and sold to the Fund at the option
of the issuer. The price and coupon of the security is fixed at the time of the
commitment. At the time of entering into the agreement the Fund is paid a
commitment fee which is typically approximately 0.5% of the aggregate purchase
price of the security which the Fund has committed to purchase. The Fund will at
all times maintain a segregated account with its custodian of cash or liquid
securities in an amount equal to the purchase price of the securities underlying
the commitment. There can be no assurance that the securities subject to a
standby commitment will be issued, and the value of the security, if issued, on
the delivery date may be more or less than its purchase price.

      Portfolio Strategies Involving Indexed and Inverse Securities, Options,
Futures and Foreign Exchange Transactions. Certain Funds may use derivative
instruments, including indexed and inverse securities, options and futures and
purchase and sell foreign exchange. Transactions involving such instruments
expose these Funds to certain risks. Each Fund's use of these instruments and
the associated risks are described in detail in Annex B of the Appendix attached
to this Prospectus.

Risks of High Yield Securities

      The Developing Capital Markets Focus Fund, High Current Income Fund,
International Equity Focus Fund and Capital Focus Fund may invest a substantial
portion of their assets in high yield, high risk securities or junk bonds, which
are regarded as being predominantly speculative as to the issuer's ability to
make payments of principal and interest. Investment in such securities involves
substantial risk. Issuers of junk bonds may be highly leveraged and may not have
available to them more traditional methods of financing. Therefore, the risks
associated with acquiring the securities of such issuers generally are greater
than is the case with higher-rated securities. For example, during an economic
downturn or a sustained period of rising interest rates, issuers of high yield
securities may be more likely to experience financial stress, especially if such
issuers are highly leveraged. During recessionary periods, such issuers may not
have sufficient revenues to meet their interest payment obligations. The
issuer's ability to service its debt obligations also may be adversely affected
by specific issuer developments, or the issuer's inability to meet specific
projected business forecasts, or the unavailability of additional financing. The
risk of loss due to default by the issuer is significantly greater for the
holders of junk bonds because such securities may be unsecured and may be
subordinated to other creditors of the issuer. While the high yield securities
in which the Developing Capital Markets Focus Fund, High Current Income Fund,
International Equity Focus Fund and Capital Focus Fund may invest normally do
not include securities which, at the time of investment, are in default or the
issuers of which are in bankruptcy, there can be no assurance that such events
will not occur after a Fund purchases a particular security, in which case a
Fund may experience losses and incur costs.

      In an effort to minimize the risk of issuer default or bankruptcy, the
Developing Capital Markets Focus Fund, High Current Income Fund, International
Equity Focus Fund and Capital Focus Fund each will diversify its holdings among
many issuers. However, there can be no assurance that diversification will
protect a Fund from widespread defaults brought about by a sustained economic
downturn.

      High yield securities frequently have call or redemption features that
would permit an issuer to repurchase the security from the Fund. If a call were
exercised by the issuer during a period of declining interest rates, the Fund
likely would have to replace such called security with a lower yielding
security, thus decreasing the net investment income to the Fund and dividend to
shareholders.

      High yield securities tend to be more volatile than higher-rated
fixed-income securities, so that adverse economic events may have a greater
impact on their prices and yields than on higher-rated fixed-income securities.
Zero coupon bonds and bonds which pay interest and/or principal in additional
bonds rather than in cash are especially volatile. Like higher-rated
fixed-income securities, junk bonds are generally purchased and sold through
dealers who make a market in such securities for their own accounts. However,
there are fewer dealers in this market, which may be less liquid than the market
for higher-rated fixed-income securities, even under normal economic conditions.
Also, there may be significant disparities in the prices quoted for such bonds
by various dealers. Adverse economic conditions or investor perceptions (whether
or not based on economic fundamentals) may impair the liquidity of this market,
and may cause the prices the Developing Capital Markets Focus Fund, High Current
Income Fund, International Equity Focus Fund and Capital Focus Fund receive for
their junk bonds to be reduced, or a Fund may experience difficulty in
liquidating a portion of its portfolio when necessary to meet the Fund's
liquidity needs or in response to a specific economic event such as a
deterioration in the creditworthiness of the issuer. Under such conditions,
judgement may play a greater role in valuing certain of each Fund's portfolio
securities than in the case of securities trading in a more liquid market.

      It is expected that a significant portion of the high yield securities
acquired by the Capital Focus Fund will be purchase upon issuance, which may
involve special risks because the securities so acquired are new issues. In such
instances the Capital Focus Fund may be a substantial purchaser of the issue and
therefore have the opportunity


                                       A-6
<PAGE>   206

to participate in structuring the terms of the offering. Although this may
enable the Capital Focus Fund to seek to protect itself against certain of such
risks, the considerations discussed herein would nevertheless remain applicable.

      Adverse publicity and investor perceptions, which may not be based on
fundamental analysis, also may decrease the value and liquidity of junk bonds,
particularly in a thinly traded market. Factors adversely affecting the market
value of such securities are likely to affect adversely the net asset value of
the Developing Capital Markets Focus Fund, High Current Income Fund, Capital
Focus Fund and International Equity Focus Fund. In addition, each Fund may incur
additional expenses to the extent that it is required to seek recovery upon a
default on a portfolio holding or to participate in the restructuring of the
obligation.

      Sovereign Debt. The junk bonds in which the Developing Capital Markets
Focus Fund, High Current Income Fund, Capital Focus Fund and International
Equity Focus Fund may invest include junk bonds issued by sovereign entities.
Investment in such sovereign debt involves a high degree of risk. The
governmental entity that controls the repayment of sovereign debt may not be
able or willing to repay the principal and/or interest when due in accordance
with the terms of such debt. A governmental entity's willingness or ability to
repay principal and interest due in a timely manner may be affected by, among
other factors, its cash flow situation, the extent of its foreign reserves, the
availability of sufficient foreign exchange on the date a payment is due, the
relative size of the debt service burden to the economy as a whole, the
governmental entity's policy towards the International Monetary Fund and the
political constraints to which a governmental entity may be subject.
Governmental entities may also be dependent on expected disbursements from
foreign governments, multilateral agencies and others abroad to reduce principal
and interest arrearages on their debt. The commitment on the part of these
governments, agencies and others to make such disbursements may be conditioned
on a governmental entity's implementation of economic reforms and/or economic
performance and the timely service of such debtor's obligations. Failure to
implement such reforms, achieve such levels of economic performance or repay
principal or interest when due may result in the cancellation of such third
parties' commitments to lend funds to the governmental entity, which may further
impair such debtor's ability or willingness to timely service its debts.
Consequently, governmental entities may default on their sovereign debt.

      Holders of sovereign debt, including the Developing Capital Markets Focus
Fund, High Current Income Fund, Capital Focus Fund and International Equity
Focus Fund may be requested to participate in the rescheduling of such debt and
to extend further loans to governmental entities. In the event of a default by a
governmental entity, there may be few or no effective legal remedies available
to a Fund and there can be no assurance a Fund will be able to collect on
defaulted sovereign debt in whole or in part.

Insurance Law Restrictions

      In order for shares of the Company's Funds to remain eligible investments
for the Separate Accounts, it may be necessary, from time to time, for a Fund to
limit its investments in certain types of securities in accordance with the
insurance laws or regulations of the various states in which the Contracts are
sold.

      The New York insurance law requires that investments of each Fund be made
with the degree of care of an "ordinarily prudent person." The Investment
Adviser believes that compliance with this standard will not have any negative
impact on the performance of any of the Funds.

Other Considerations

      The Investment Adviser will use its best efforts to assure that each Fund
of the Company complies with certain investment limitations of the Internal
Revenue Service to assure favorable income tax treatment for the Contracts. It
is not expected that such investment limitations will materially affect the
ability of any Fund to achieve its investment objective.

its average net assets) of which $78,164 was voluntarily waived by MLAM.

      During the Company's fiscal year ended December 31, 1997, the total
operating expenses attributable to the Class B Shares of the Company's Funds
(including the advisory fees paid to the Investment Adviser), before any fee
waiver or reimbursement of a portion of such expenses, expressed as a percentage
of each Fund's average net assets, were as follows: 0.96% of the Special Value
Focus Fund's average net assets, 0.82% of the Basic Value Focus Fund's average
net assets, and 1.58% of the Developing Capital Markets Focus Fund's average net
assets.

      The Investment Adviser has entered into a sub-advisory agreement (the
"Sub-Advisory Agreement") with MLAM U.K., an indirect wholly owned subsidiary of
ML & Co., and an affiliate of the Investment Adviser, pursuant to which the
Investment Adviser pays MLAM U.K. a fee for providing investment advisory
services to the Investment Adviser with respect to the Funds in an amount to be
determined from time to time by the Investment Adviser and MLAM U.K. but in no
event in excess of the amount that the Investment Adviser actually receives for
providing services to the Funds pursuant to the Investment Advisory Agreement.

      The Investment Adviser and Merrill Lynch Life Agency, Inc. ("MLLA") have
entered into agreements which limit the operating expenses, exclusive of any
distribution fees imposed on shares of Class B Common Stock, paid by each Fund
in a given year to 1.25% of its average daily net assets (the "Reimbursement
Agreements"). The Reimbursement Agreement provides that any such expenses in
excess of 1.25% of average daily net assets will be reimbursed to the Fund by
the Investment Adviser which, in turn, will be reimbursed by MLLA.

      The Investment Adviser has entered into administrative services agreements
with certain Insurance Companies, including MLLIC and ML of New York, pursuant
to which the Investment Adviser compensates such companies for administrative
responsibilities relating to the Company which are performed by such Insurance
Companies.

Code of Ethics

      The Board of Directors of the Company has adopted a Code of Ethics under
Rule 17j-1 of the Act which incorporates the Code of Ethics of the Investment
Adviser (together, the "Codes"). The Codes significantly restrict the personal
investing activities of all employees of the Investment Adviser and, as
described below, impose additional, more onerous, restrictions on fund
investment personnel.

      The Codes require that all employees of the Investment Adviser preclear
any personal securities investment (with limited exceptions, such as government
securities). The preclearance requirement and associated procedures are designed
to identify any substantive prohibition or limitation applicable to the proposed
investment. The substantive restrictions applicable to all employees of the
Investment Adviser include a ban on acquiring any securities in a "hot" initial
public offering and a prohibition from profiting on short-term trading in
securities. In


                                       A-9
<PAGE>   209

addition, no employee may purchase or sell any security which at the time is
being purchased or sold (as the case may be), or to the knowledge of the
employee is being considered for purchase or sale, by any fund advised by the
Investment Adviser. Furthermore, the Codes provide for trading "blackout
periods" which prohibit trading by investment personnel of the Company within
periods of trading by the Company in the same (or equivalent) security (15 or 30
days depending upon the transaction).

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

      None of the Company's Funds has any obligation to deal with any dealer or
group of dealers in the execution of transactions in portfolio securities.
Subject to policy established by the Board of Directors of the Company, the
Investment Adviser is primarily responsible for the Company's portfolio
decisions and the placing of the Company's portfolio transactions. In placing
orders, it is the policy of each Fund to obtain the most favorable net results,
taking into account various factors, including price, dealer spread or
commission, if any, size of the transactions and difficulty of execution. While
the Investment Adviser generally seeks reasonably competitive spreads or
commissions, the Company will not necessarily be paying the lowest spread or
commission available.

      Under the Investment Company Act of 1940, persons affiliated with the
Company are prohibited from dealing with the Company as a principal in the
purchase and sale of the Company's portfolio securities unless an exemptive
order allowing such transactions is obtained from the Securities and Exchange
Commission. Affiliated persons of the Company may serve as its broker in
over-the-counter transactions conducted on an agency basis. The Securities and
Exchange Commission has issued an order permitting the Company to conduct
certain principal transactions with respect to the Domestic Money Market and
Reserve Assets Funds with Merrill Lynch Government Securities Inc. and Merrill
Lynch Money Markets Inc. in U.S. Government and Government agency securities,

                               PURCHASE OF SHARES

      The Company continuously offers shares of Class B Common Stock of the
Basic Value Focus Fund, Developing Capital Markets Focus Fund and the Special
Value Focus Fund to the Insurance Companies at prices equal to the respective
per share net asset value of the Funds. Merrill Lynch Funds Distributor, Inc.
(the "Distributor"), a wholly owned subsidiary of the Investment Adviser, acts
as the distributor of the shares.

      The Company will offer shares of Class B Stock in each of its other Funds
to the Insurance Companies at the per share price of the Class A Common Stock of
the corresponding Fund until such time as a share of Class B Common Stock is
purchased, and thereafter, the Company will continuously offer shares of Class B
Common Stock at prices equal to the respective per share net asset value of the
Class B Common Stock of the Funds. The Distributor acts as the distributor of
the shares. Net asset value is determined in the manner set forth below under
"Additional Information--Determination of Net Asset Value."

      The Company and the Distributor reserve the right to suspend the sale of
shares of each Fund in response to conditions in the securities markets or
otherwise.

                              REDEMPTION OF SHARES

      The Company is required to redeem all full and fractional shares of the
Funds for cash. The redemption price is the net asset value per share next
determined after the initial receipt of proper notice of redemption.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES

      It is the Company's intention to distribute substantially all of the net
investment income, if any, of each Fund. For dividend purposes, net investment
income of each Fund, other than the Company's Domestic Money Market and Reserve
Assets Funds, will consist of all payments of dividends or interest received by
such Fund less the estimated expenses of such Fund (including fees payable to
the Investment Adviser). Net investment income of the Domestic Money Market and
Reserve Assets Funds (from the time of the immediate preceding determination
thereof) consists of (i) interest accrued and/or discount earned (including both
original issue and market discount), (ii) plus or minus all realized and
unrealized gains (other than realized long-term capital gains) and losses on its
portfolio securities, (iii) less the estimated expenses of the respective Fund
(including the fees payable to the Investment Adviser) applicable to that
dividend period. Dividends on the Domestic Money Market and Reserve Assets Funds
are declared daily and reinvested monthly in additional full and fractional
shares of such Fund. Dividends from net investment income of the Global Bond
Focus, Government Bond, High Current Income and Prime Bond Funds are declared
and reinvested monthly in additional full and fractional shares of the
respective Funds at net asset value. Dividends from net investment income of the
Global Utility Focus Fund are declared and reinvested quarterly in additional
full and fractional shares of the Fund. Dividends from net investment income of
the American Balanced, Basic Value Focus, Capital Focus, Developing Capital
Markets Focus, Special Value Focus, Global Strategy Focus, Global Growth Focus,
Index 500, International Equity Focus, National Resources Focus and Quality
Equity Funds are declared and reinvested at least annually in additional full
and fractional shares of the respective Funds.

      All net realized long-term or short-term capital gains of the Company, if
any, other than short-term capital gains of the Domestic Money Market and
Reserve Assets Funds, are declared and distributed annually after the close of
the Company's fiscal year to the shareholders of the Fund or Funds to which such
gains are attributable. Short-term capital gains are taxable as ordinary income.

Tax Treatment of the Company

      Each Fund intends to continue to qualify as a regulated investment company
under certain provisions of the Internal Revenue Code. Under such provisions, a
Fund will not be subject to federal income tax on such part of its net ordinary
income and net realized capital gains which it distributes to shareholders. One
of the requirements to qualify for treatment as a regulated investment company
under the Code is that a Fund, among other things,


                                      A-12
<PAGE>   212

derive less than 30% of its gross income in each taxable year from gains
(without deduction of losses) from the sale or other disposition of stocks,
securities and certain options, futures or forward contracts held for less than
three months. This requirement may limit the ability of certain Funds to dispose
of certain securities at times when management of the Company might otherwise
deem such disposition appropriate or desirable.

      If a Fund earns original issue discount income in a taxable year which is
not represented by correlative cash income, or if a Fund receives property
rather than cash in payment of interest, shareholders will be allocated income
greater than the amount of cash distributed to them. In addition, the Fund may
have to dispose of securities and use the proceeds thereof to make distributions
in amounts necessary to satisfy its distribution requirements under the Code.

Tax Treatment of Insurance Companies as Shareholders

      Dividends paid by the Company from its ordinary income and distributions
of the Company's net realized capital gains are includable in the respective
Insurance Company's gross income. Distributions of the Company's net realized
long-term capital gains retain their character as long-term capital gains in the
hands of the Insurance Companies if certain requirements are met. The tax
treatment of such dividends and distributions depends on the respective
Insurance Company's tax status. To the extent that income of the Company
represents dividends on common or preferred stock, rather than interest income,
its distributions to the Insurance Companies will be eligible for the present
70% dividends received deduction applicable in the case of a life insurance
company as provided in the Code. See the Prospectus for the Contracts for a
description of the respective Insurance Company's tax status and the charges
which may be made to cover any taxes attributable to the Separate Account. Not
later than 60 days after the end of each calendar year, the Company will send to
the Insurance Companies a written notice required by the Code designating the
amount and character of any distributions made during such year.

                                PERFORMANCE DATA

      From time to time the average annual total return and yield of one or more
of the Company's Funds for various specified time periods may be included in
advertisements or information furnished by the Insurance Companies to present or
prospective Contract owners. Average annual total return and yield are computed
in accordance with formulas specified by the Securities and Exchange Commission.
In connection with its reorganization on December 6, 1996, the Global Bond Focus
Fund (i) acquired substantially all of the assets and assumed substantially all
the liabilities of the International Bond Fund, a separate Fund of the Company,
(ii) implemented a change in its investment objective and policies from seeking
high current income from a global portfolio of fixed income securities,
including non-investment grade securities, to seeking a high total investment
return by investing in a global portfolio of investment grade fixed income
securities and (iii) changed its name from the World Income Focus Fund to its
current name. For the period from the commencement of the World Income Focus
Fund's operations through its reorganization on December 6, 1996, the portfolio
of the Fund included debt securities rated below investment grade (i.e., junk
bonds). On December 6, 1996, the Government Bond Fund (i) implemented a change
in its investment objective so that the Fund may invest in any debt securities
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
without regard to remaining maturity and (ii) changed its name from the
Intermediate Government Bond Fund to its current name. For the period from the
commencement of the Fund's operations through December 6, 1996, the portfolio of
the Intermediate Government Bond Fund consisted primarily of intermediate-term
debt securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities with a maximum maturity not to exceed fifteen years. As a
result of the foregoing changes in the investment objective of each of the
Global Bond Focus Fund and the Government Bond Fund, the performance information
set forth herein and in the Statement of Additional Information for the fiscal
year ended December 31, 1996 may not be indicative of such Fund's future
performance.

      Average annual total return quotations for the specified periods will be
computed by finding the average annual compounded rates of return (based on net
investment income and any realized and unrealized capital gains or losses on
portfolio investments over such periods) that would equate the initial amount
invested to the redeemable value of such investment at the end of each period.
Average annual total return will be computed assuming all dividends and
distributions are reinvested and taking into account all applicable recurring
and nonrecurring expenses.


                                      A-13
<PAGE>   213

      Yield quotations will be computed based on a 30-day period by dividing (a)
the net income based on the yield to maturity of each security earned during the
period by (b) the average daily number of shares outstanding during the period
that were entitled to receive dividends multiplied by the offering price per
share on the last day of the period. Because no shares of Class B Common Stock
of the Prime Bond Fund, the High Current Income Fund, the Global Bond Focus Fund
and the Government Bond Fund were in issue prior to December 31, 1997, the yield
information below relates to Class A Common Stock only. The yield for the 30-day
period ending December 31, 1997 was 6.05% for the Prime Bond Fund, 8.73% for the
High Current Income Fund, 6.11% for the Global Bond Focus Fund and 5.52% for the
Government Bond Fund.

      Total return and yield figures are based on the Fund's historical
performance and are not intended to indicate future performance. The Fund's
total return and yield will vary depending on market conditions, the securities
comprising the Fund's portfolio, the Fund's operating expenses and the amount of
realized and unrealized net capital gains or losses during the period. The value
of an investment in the Fund will fluctuate and an investor's shares, when
redeemed, may be worth more or less than their original cost. The yield and
total return quotations may be of limited use for comparative purposes because
they do not reflect charges imposed at the Separate Account level which, if
included, would decrease the yield.

      On occasion, one or more of the Company's Funds may compare its
performance to that of the S&P 500 Index, the Value Line Composite Index, the
Dow Jones Industrial Average, or performance data published by Lipper Analytical
Services, Inc., or Variable Annuity Research Data Service or contained in
publications such as Morningstar Publications, Inc., Chase Investment
Performance Digest, Money Magazine, U.S. News & World Report, Business Week,
Financial Services Weekly, Kiplinger Personal Finances, CDA Investment
Technology, Inc., Forbes Magazine, Fortune Magazine, Wall Street Journal, USA
Today, Barrons, Strategic Insight, Donaghues, Investors Business Daily and
Ibbotson Associates. As with other performance data, performance comparisons
should not be considered indicative of the Fund's relative performance for any
future period.

                                DISTRIBUTION PLAN

      The Funds have adopted a Distribution Plan (the "Plan") with regards to
the Class B Common Stock of each Fund, pursuant to Rule 12b-1 under the
Investment Company Act. The Plan permits the Company to pay to each Insurance
Company that enters into an agreement with the Company to provide distribution
related services to Contract owners, a fee, at the end of each month, of up to
0.15% of the net asset value of the Class B Common Stock of each Fund held by
such Insurance Company. Such services include, but are not limited to, (a) the
printing and mailing of Fund prospectuses, statements of additional information,
any supplements thereto and shareholder reports for existing and prospective
Contract owners, (b) services relating to the development, preparation, printing
and mailing of Company advertisements, sales literature and other promotional
materials describing and/or relating to the Company and including materials
intended for use within the Insurance Company, (c) holding seminars and sales
meetings designed to promote the distribution of the Class B Shares of the
Funds, (d) obtaining information and providing explanations to Contract owners
regarding the investment objectives and policies and other information about the
Company and its Funds, including the performance of the Funds, (e) training
sales personnel regarding the Company and the Funds, (f) compensating sales
personnel in connection with the allocation of cash values and premiums of the
Separate Accounts of the Insurance Company, (g) providing personal services
and/or maintenance of the Separate Accounts with respect to Class B Shares of
the Funds attributable to such accounts, and (h) financing any other activity
that the Company's Board of Directors determines is primarily intended to result
in the sale of Class B Shares.

                             ADDITIONAL INFORMATION

Determination of Net Asset Value

      The net asset value of each class of shares of each Fund is determined
once daily by the Investment Adviser immediately after the declaration of
dividends, if any, and is determined as of fifteen minutes following the close
of trading (generally 4:00 p.m., New York time) on each day the New York Stock
Exchange ("NYSE") is open for business. The NYSE is open on business days other
than national holidays and Good Friday. The net asset value


                                      A-14
<PAGE>   214

per share of each class of shares of a Fund other than the Domestic Money Market
and Reserve Assets Funds is computed by dividing the sum of the value of the
securities plus any cash or other assets (including interest and dividends
accrued) held by such Fund and attributable to such class minus all liabilities
(including accrued expenses) attributable to such class by the total number of
shares of such class outstanding of that Fund at such time, rounded to the
nearest cent. Expenses, including the investment advisory fees payable to the
Investment Adviser, are accrued daily. Since the net investment income of the
Domestic Money Market and Reserve Assets Funds (including realized and
unrealized gains and losses on their portfolio securities) are declared as a
dividend each time the net income of the Funds are determined (see "Dividends,
Distributions and Taxes"), the net asset value per share of the Funds normally
remains at $1.00 per share immediately after each such determination and
dividend declaration.

      Except with respect to securities held by the Domestic Money Market and
Reserve Assets Funds having a remaining maturity of 60 days or less, securities
held by each Fund will be valued as follows: Portfolio securities that are
traded on stock exchanges are valued at the last sale price (regular way) as of
the close of business on the day the securities are being valued, or, lacking
any sales, at the last available bid price for long positions and at the last
available ask price for short positions. Long positions in securities traded in
the over-the-counter ("OTC") market are valued at the last available bid price
in the OTC market prior to the time of valuation, provided however that the
Index 500 Fund will value its portfolio holdings which trade on the NASDAQ
national market system at the last sale price prior to the time of valuation.
Short positions in securities traded in the OTC market are valued at the last
available ask price in the OTC market prior to the time of valuation. Portfolio
securities that are traded both in the OTC market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the OTC market. When a
Fund writes an option, the amount of the premium received is recorded on the
books as an asset and an equivalent liability. The amount of the liability is
subsequently valued to reflect the current market value of the option written,
based upon the last sale price in the case of exchange-traded options or, in the
case of options traded in the OTC market, the last asked price. Options
purchased are valued at their last sale price in the case of exchange-traded
options or, in the case of options traded in the OTC market, the last bid price.
Futures contracts are valued at settlement price at the close of the applicable
exchange. Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Directors of the Company. Any assets or liabilities
initially expressed in terms of non-U.S. dollar currencies are translated into
U.S. dollars at the prevailing market rates as quoted by one or more banks or
dealers on the day of valuation. Securities held by the Domestic Money Market
and Reserve Assets Funds with a remaining maturity of 60 days or less are valued
on an amortized cost basis, unless particular circumstances dictate otherwise.

      The Company has used pricing services, including Merrill Lynch Securities
Pricing(TM) Service ("MLSPS"), to value securities held by the High Current
Income and Prime Bond Funds and to value bonds held by other of the Company's
Funds. The Board of Directors of the Company has examined the methods used by
the pricing services in estimating the value of securities held by the Funds and
believes that such methods will reasonably and fairly approximate the price at
which those securities may be sold and result in a good faith determination of
the fair value of such securities; however, there is no assurance that
securities can be sold at the prices at which they are valued. During the fiscal
year ended December 31, 1997, American Balanced Fund, Global Strategy Focus
Fund, Global Utility Focus Fund, High Current Income Fund, Government Bond Fund,
Prime Bond Fund and Global Bond Focus Fund paid MLSPS $248, $239, $43, $7,008,
$1,676, $8,877 and $116, respectively.

entitled to vote on matters concerning only that class. Pursuant to the
Investment Company Act of 1940 and the rules and regulations thereunder, certain
matters approved by a vote of all shareholders of the Company may not be binding
on a class whose shareholders have not approved such matter. Each issued and
outstanding share of a class is entitled to one vote and to participate equally
in dividends and distributions declared with respect to such class and in net
assets of such class upon liquidation or dissolution remaining after
satisfaction of outstanding liabilities. The shares of each class, when issued,
will be fully paid and nonassessable, have no preference, preemptive,
conversion, exchange or similar rights, and will be freely transferable. Holders
of shares of any class are entitled to redeem their shares as set forth under
"Redemption of Shares." Shares do not have cumulative voting rights and the
holders of more than 50% of the shares of the Company voting for the election of
directors can elect all of the directors of the Company if they choose to do so
and in such event the holders of the remaining shares would not be able to elect
any directors. The Company does not intend to hold meetings of shareholders
unless under the Investment Company Act of 1940 shareholders are required to act
on any of the following matters: (i) election of directors; (ii) approval of an
investment advisory agreement; (iii) approval of a distribution agreement; and
(iv) ratification of the selection of independent accountants.

                                     ANNEX A

         DESCRIPTION OF TEMPORARY INVESTMENTS AND CORPORATE BOND RATINGS

U.S. Government Securities

      The Domestic Money Market Fund, Reserve Assets Fund, Capital Focus Fund
and the Government Bond Fund (and, for temporary or defensive purposes, each
other Fund) may invest in the various types of marketable securities issued by
or guaranteed as to principal and interest by the U.S. Government and supported
by the full faith and credit of the U.S. Treasury. U.S. Treasury obligations
differ mainly in the length of their maturity. Treasury bills, the most
frequently issued marketable government security, have a maturity of up to one
year and are issued on a discount basis.

Government Agency Securities

      The Domestic Money Market Fund, Reserve Assets Fund, Capital Focus Fund
and the Government Bond Fund (and, for temporary or defensive purposes, each
other Fund) may invest in government agency securities, which are debt
securities issued by government sponsored enterprises, federal agencies and
international institutions. Such securities are not direct obligations of the
Treasury but involve government sponsorship or guarantees by government agencies
or enterprises. The Funds may invest in all types of government agency
securities currently outstanding or to be issued in the future.

Depositary Institutions Money Instruments

      The Domestic Money Market Fund, Reserve Assets Fund and Capital Focus Fund
(and, for temporary or defensive purposes, each other Fund) may invest in
depositary institutions money instruments, such as certificates of deposit,
including variable rate certificates of deposit, bankers' acceptances, time
deposits and bank notes. Certificates of deposit are generally short-term,
interest-bearing negotiable certificates issued by commercial banks, savings
banks or savings and loan associations against funds deposited in the issuing
institution. Variable rate certificates of deposit are certificates of deposit
on which the interest rate is periodically adjusted prior to their stated
maturity, usually at 30, 90 or 180 day intervals ("coupon dates"), based upon a
specified market rate. As a result of these adjustments, the interest rate on
these obligations may be increased or decreased periodically. Often, dealers
selling variable rate certificates of deposit to the Funds agree to repurchase
such instruments, at the Funds' option, at par on the coupon dates. The dealers'
obligations to repurchase these instruments are subject to conditions imposed by
the various dealers; such conditions typically are the continued credit standing
of the issuer and the existence of reasonably orderly market conditions. The
Funds are also able to sell variable rate certificates of deposit in the
secondary market. Variable rate certificates of deposit normally carry a higher
interest rate than comparable fixed rate certificates of deposit because
variable rate certificates of deposit generally have a longer stated maturity
than comparable fixed rate certificates of deposit. As a matter of policy, the
Domestic Money Market Fund will invest only in these types of instruments issued
by U.S. issuers.

      A bankers' acceptance is a time draft drawn on a commercial bank by a
borrower usually in connection with an international commercial transaction (to
finance the import, export, transfer or storage of goods). The borrower is
liable for payment as well as the bank, which unconditionally guarantees to pay
the draft at its face amount on the maturity date. Most acceptances have
maturities of six months or less and are traded in secondary markets prior to
maturity.

      The Reserve Assets Fund and Capital Focus Fund (and, for temporary or
defensive purposes, the Natural Resources Focus Fund, Global Strategy Focus
Fund, Global Bond Focus Fund, Global Utility Focus Fund, International Equity
Focus Fund, Developing Capital Markets Focus Fund and the Quality Equity Fund)
may invest in certificates of deposit and bankers' acceptances issued by foreign
branches or subsidiaries of U.S. banks ("Eurodollar" obligations) or U.S.
branches or subsidiaries of foreign banks ("Yankeedollar" obligations). The Fund
may invest only in Eurodollar obligations which by their terms are general
obligations of the U.S. parent bank and meet the other criteria discussed below.
Yankeedollar obligations in which the Fund may invest must be issued


                                    Annex A-1
<PAGE>   219

by U.S. branches or subsidiaries of foreign banks which are subject to state or
federal banking regulations in the U.S. and by their terms must be general
obligations of the foreign parent. In addition, the Fund will limit its
investments in Yankeedollar obligations to obligations issued by banking
institutions with more than $1 billion in assets.

      The Reserve Assets Fund and Capital Focus Fund (and, for temporary or
defensive purposes, the Natural Resources Focus Fund, Global Strategy Focus
Fund, Global Bond Focus Fund, Global Utility Focus Fund, International Equity
Focus Fund, Developing Capital Markets Focus Fund and the Quality Equity Fund)
may also invest in U.S. dollar-denominated obligations of foreign depository
institutions and their foreign branches and subsidiaries, such as certificates
of deposit, bankers' acceptances, time deposits and deposit notes. The
obligations of such foreign branches and subsidiaries may be the general
obligation of the parent bank or may be limited to the issuing branch or
subsidiary by the terms of the specific obligation or by government regulation.
Such investments will only be made if determined to be of comparable quality to
other investments permissible for the Reserve Assets Fund. The Reserve Assets
Fund will not invest more than 25% of its total assets (taken at market value at
the time of each investment) in these obligations.

      Except as otherwise provided above with respect to investment in
Yankeedollar and other foreign bank obligations no Fund may invest in any bank
money instrument issued by a commercial bank or a savings and loan association
unless the bank or association is organized and operating in the United States,
has total assets of at least $1 billion and its deposits are insured by the
Federal Deposit Insurance Corporation (the "FDIC"); provided that this
limitation shall not prohibit the investment of up to 10% of the total assets of
a Fund (taken at market value at the time of each investment) in certificates of
deposit issued by banks and savings and loan associations with assets of less
than $1 billion if the principal amount of each such certificate of deposit is
fully insured by the FDIC.

Short-Term Debt Instruments

      The Domestic Money Market Fund, Reserve Assets Fund and Capital Focus Fund
(and, for temporary or defensive purposes, each other Fund) may invest in
commercial paper (including variable amount master demand notes and insurance
company funding agreements), which refers to short-term, unsecured promissory
notes issued by corporations, partnerships, trusts and other entities to finance
short-term credit needs and by trusts issuing asset-backed commercial paper.
Commercial paper is usually sold on a discount basis and has a maturity at the
time of issuance not exceeding nine months. Variable amount master demand notes
are demand obligations that permit the investment of fluctuating amounts at
varying market rates of interest pursuant to arrangements between the issuer and
a commercial bank acting as agent for the payees of such notes, whereby both
parties have the right to vary the amount of the outstanding indebtedness on the
notes. Because variable amount master notes are direct lending arrangements
between the lender and borrower, it is not generally contemplated that such
instruments will be traded and there is no secondary market for the notes.
Typically, agreements relating to such notes provide that the lender may not
sell or otherwise transfer the note without the borrower's consent. Such notes
provide that the interest rate on the amount outstanding is adjusted
periodically, typically on a daily basis, in accordance with a stated short-term
interest rate benchmark. Because the interest rate of a variable amount master
note is adjusted no less often than every 60 days and since repayment of the
note may be demanded at any time, the Investment Adviser values such a note in
accordance with the amortized cost basis described under "Determination of Net
Asset Value" in the Statement of Additional Information.

      The Domestic Money Market Fund and Reserve Assets Fund may also invest in
nonconvertible debt securities issued by entities or asset-backed nonconvertible
debt securities issued by trusts (e.g., bonds and debentures) with no more than
397 days (13 months) remaining to maturity at date of settlement. Short-term
debt securities with a remaining maturity of less than one year tend to become
extremely liquid and are traded as money market securities. For a discussion of
the ratings requirements of the Funds' portfolio securities, see "Portfolio
Restrictions" in the Prospectuses to the Domestic Money Market Fund and Reserve
Assets Fund.

      The Reserve Assets Fund and Capital Focus Fund (and, for temporary or
defensive purposes, the Natural Resources Focus Fund, Global Strategy Focus
Fund, Global Bond Focus Fund, Global Utility Focus Fund, International Equity
Focus Fund and Developing Capital Markets Focus Fund) may also invest in U.S.
dollar-

denominated commercial paper and other short-term obligations issued by foreign
entities. Such investments are subject to quality standards similar to those
applicable to investments in comparable obligations of domestic issuers.
Investments in foreign entities in general involve the same risks as those
described in the Statement of Additional Information in connection with
investments in Eurodollar, Yankeedollar and foreign bank obligations.

Repurchase Agreements

      Repurchase Agreements; Purchase and Sale Contracts. Each Fund may invest
in securities pursuant to repurchase agreements or purchase and sale contracts.
Under a repurchase agreement, the seller agrees, upon entering into the contract
with the Fund, to repurchase a security (typically a security issued or
guaranteed by the U.S. government) at a mutually agreed upon time and price,
thereby determining the yield during the term of the agreement. This results in
a fixed yield for the Fund insulated from fluctuations in the market value of
the underlying security during such period, although, to the extent the
repurchase agreement is not denominated in U.S. dollars, the Fund's return may
be affected by currency fluctuations. Repurchase agreements may be entered into
only with a member bank of the Federal Reserve System, a primary dealer in U.S.
government securities or an affiliate thereof. A purchase and sale contract is
similar to a repurchase agreement, but purchase and sale contracts, unlike
repurchase agreements, allocate interest on the underlying security to the
purchaser during the term of the agreement and generally do not require the
seller to provide additional securities in the event of a decline in the market
value of the purchased security during the term of the agreement. If the seller
were to default on its obligation to repurchase a security under a repurchase
agreement or purchase and sale contract and the market value of the underlying
security at such time was less than the Fund had paid to the seller, the Fund
would realize a loss. Repurchase agreements maturing in more than seven days
will be considered "illiquid securities." The Domestic Money Markets and Reserve
Assets Funds will not enter into repurchase agreements maturing in more than 30
days.

      Reverse Repurchase Agreements. The Domestic Money Market and Reserve
Assets Funds may enter into reverse repurchase agreements, which involve the
sale of money market securities held by the Funds, with an agreement to
repurchase the securities at an agreed upon price, date, and interest payment.
The Funds will use the proceeds of the reverse repurchase agreements to purchase
other money market securities either maturing, or under an agreement to resell,
at a date simultaneous with or prior to the expiration of the reverse repurchase
agreement. The Funds will utilize reverse repurchase agreements when the
interest income to be earned from the investment of the proceeds of the
transaction is greater than the interest expense of the reverse repurchase
transaction. A separate account of the applicable Fund will be established with
the Custodian consisting of cash or liquid securities having a market value at
all times at least equal in value to the proceeds received on any sale subject
to repurchase plus accrued interest.

Description of Corporate Bond Ratings

      Moody's Investors Service, Inc. ("Moody's"):

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

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

            A--Bonds which are rated A possess many favorable investment
      attributes and are to be considered as upper medium-grade obligations.
      Factors giving security to principal and interest are considered adequate
      but elements may be present which suggest a susceptibility to impairment
      sometime in the future.


                                    Annex A-3
<PAGE>   221

            Baa--Bonds which are rated Baa are considered medium-grade
      obligations, i.e., they are neither highly protected nor poorly secured.
      Interest payments and principal security appear adequate for the present
      but certain protective elements may be lacking or may be
      characteristically unreliable over any length of time. Such bonds lack
      outstanding investment characteristics and in fact have speculative
      characteristics as well.

            Ba--Bonds which are rated Ba are judged to have speculative
      elements; their future cannot be considered as well assured. Often the
      protection of interest and principal payments may be very moderate and
      thereby not well safeguarded both during good and bad times over the
      future. Uncertainty of position characterizes bonds in this class.

            B--Bonds which are rated B generally lack characteristics of a
      desirable investment. Assurance of interest and principal payments or of
      maintenance of other terms of the contract over any period of time may be
      small.

            Caa--Bonds which are rated Caa are of poor standing. Such issues may
      be in default or there may be present elements of danger with respect to
      principal or interest.

            Ca--Bonds which are rated Ca represent obligations which are
      speculative in a high degree. Such issues are often in default or have
      other market shortcomings.

            C--Bonds which are rated C are the lowest rated class of bonds and
      issues so rated can be regarded as having extremely poor prospects of ever
      attaining any real investment standing.

      Note: Moody's applies numerical modifiers, 1, 2 and 3 in each generic
rating classification from Aa through B in 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.

      Standard & Poor's Ratings Services ("Standard & Poor's"):

            AAA--This is the highest rating assigned by Standard & Poor's to a
      debt obligation and indicates an extremely strong capacity to pay
      principal and interest.

            AA--Bonds rated AA also qualify as high-quality debt obligations.
      Capacity to pay principal and interest is very strong, and in the majority
      of instances they differ from AAA issues only in small degree.

            A--Bonds rated A have a strong capacity to pay principal and
      interest, although they are somewhat more susceptible to the adverse
      effects of changes in circumstances and economic conditions.

            BBB--Bonds rated BBB are regarded as having an adequate capacity to
      pay principal and interest. Whereas they normally exhibit adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      principal and interest for bonds in this category than for bonds in the A
      category.

            BB--B--CCC--CC--Bonds rated BB, B, CCC, and CC are regarded, on
      balance, as predominantly speculative with respect to the issuer's
      capacity to pay interest and repay principal in accordance with the terms
      of the obligations. BB indicates the lowest degree of speculation and CC
      the highest degree of speculation. While such bonds will likely have some
      quality and protective characteristics, these are outweighed by large
      uncertainties or major risk exposures to adverse conditions.

            NR--Not rated by the indicated rating agency.

            Plus (+) or Minus (-): The ratings from "AA" to "B" may be modified
      by the addition of a plus or minus sign to show relative standing within
      the major rating categories.

<PAGE>   223

                                     ANNEX B

                      DESCRIPTION OF DERIVATIVE INSTRUMENTS

      Certain Funds of the Company are authorized to use derivative instruments,
including indexed and inverse securities, options, and futures, and to purchase
and sell foreign exchange, as described below. Such instruments are referred to
collectively herein as "Strategic Instruments."

Indexed and Inverse Securities

      The Domestic Money Market Fund, the Global Bond Focus Fund, the Global
Strategy Focus Fund, the Global Utility Focus Fund, the Government Bond Fund,
the Index 500 Fund, the International Equity Focus Fund, the Natural Resources
Focus Fund, the Prime Bond Fund, the Developing Capital Markets Focus Fund, the
Global Growth Focus Fund and the Reserve Assets Fund may invest in securities
the potential return of which is based on the change in particular measurements
of value or rate (an "index"). As an illustration, a Fund may invest in a debt
security that pays interest and returns principal based on the change in the
value of an interest rate index (such as the prime rate or federal funds rate),
a securities index (such as the Standard & Poor's 500 Composite Index (the "S&P
500") or a more narrowly-focused index such as the AMEX Oil & Gas Index) or a
basket of securities, or based on the relative changes of two indices. In
addition, the Developing Capital Markets Focus Fund, the Global Strategy Focus
Fund, the International Equity Focus Fund and the Natural Resources Focus Fund
may invest in securities the potential return of which is based inversely on the
change in an index. For example, these Funds may invest in securities that pay a
higher rate of interest when a particular index decreases and pay a lower rate
of interest (or do not fully return principal) when the value of the index
increases. If the Fund invests in such securities, it may be subject to reduced
or eliminated interest payments or loss of principal in the event of an adverse
movement in the relevant index or indices.

      Certain indexed and inverse securities may have the effect of providing
investment leverage because the rate of interest or amount of principal payable
increases or decreases at a rate that is a multiple of the changes in the
relevant index. As a consequence, the market value of such securities may be
substantially more volatile than the market values of other debt securities. The
Company believes that indexed and inverse securities may provide portfolio
management flexibility that permits Funds to seek enhanced returns, hedge other
portfolio positions or vary the degree of portfolio leverage with greater
efficiency than would otherwise be possible under certain market conditions.


Options on Securities and Securities Indices

      Purchasing Options. The Developing Capital Markets Focus Fund, the Global
Bond Focus Fund, the Global Strategy Focus Fund, the Global Utility Focus Fund,
the Index 500 Fund, the International Equity Focus Fund, the Global Growth Focus
Fund, and the Natural Resources Focus Fund are each authorized to purchase put
options on securities held in its portfolio or securities indices the
performance of which is substantially correlated with securities held in its
portfolio. When a Fund purchases a put option, in consideration for an upfront
payment (the "option premium") the Fund acquires a right to sell to another
party specified securities owned by the Fund at a specified price (the "exercise
price") on or before a specified date (the "expiration date"), in the case of an
option on securities, or to receive from another party a payment based on the
amount a specified securities index declines below a specified level on or
before the expiration date, in the case of an option on a securities index. The
purchase of a put option limits the Fund's risk of loss in the event of a
decline in the market value of the portfolio holdings underlying the put option
prior to the option's expiration date. If the market value of the portfolio
holdings associated with the put option increases rather than decreases,
however, the Fund will lose the option premium and will consequently realize a
lower return on the portfolio holdings than would have been realized without the
purchase of the put.


                                    Annex B-1
<PAGE>   224

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Index 500 Fund, the International Equity Focus
Fund, the Global Growth Focus Fund and the Natural Resources Focus Fund are each
authorized to purchase call options on securities it intends to purchase or
securities indices the performance of which are substantially correlated with
the performance of the types of securities it intends to purchase. When a Fund
purchases a call option, in consideration for the option premium the Fund
acquires a right to purchase from another party specified securities at the
exercise price on or before the expiration date, in the case of an option on
securities, or to receive from another party a payment based on the amount a
specified securities index increases beyond a specified level on or before the
expiration date, in the case of an option on a securities index. The purchase of
a call option may protect the Fund from having to pay more for a security as a
consequence of increases in the market value for the security during a period
when the Fund is contemplating its purchase, in the case of an option on a
security, or attempting to identify specific securities in which to invest in a
market the Fund believes to be attractive, in the case of an option on an index
(an "anticipatory hedge"). In the event the Fund determines not to purchase a
security underlying a call option, however, the Fund may lose the entire option
premium.

      Each Fund is also authorized to purchase put or call options in connection
with closing out put or call options it has previously sold.

      Writing Options. The American Balanced Fund, the Basic Value Focus Fund,
the Developing Capital Markets Focus Fund, the Special Value Focus Fund, the
Global Bond Focus Fund, the Global Strategy Focus Fund, the Global Utility Focus
Fund, the Index 500 Fund, the International Equity Focus Fund, the Natural
Resources Focus Fund, the Global Growth Focus Fund, the Capital Focus Fund and
the Quality Equity Fund are each authorized to write (i.e., sell) call options
on securities held in its portfolio or securities indices the performance of
which is substantially correlated with securities held in its portfolio. When a
Fund writes a call option, in return for an option premium the Fund gives
another party the right to buy specified securities owned by the Fund at the
exercise price on or before the expiration date, in the case of an option on
securities, or agrees to pay to another party an amount based on any gain in a
specified securities index beyond a specified level on or before the expiration
date, in the case of an option on a securities index. The Fund may write call
options to earn income, through the receipt of option premiums. In the event the
party to which the Fund has written an option fails to exercise its rights under
the option because the value of the underlying securities is less than the
exercise price, the Fund will partially offset any decline in the value of the
underlying securities through the receipt of the option premium. By writing a
call option, however, the Fund limits its ability to sell the underlying
securities, and gives up the opportunity to profit from any increase in the
value of the underlying securities beyond the exercise price, while the option
remains outstanding.

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Global Utility Focus Fund, the Index 500 Fund,
the International Equity Focus Fund, the Global Growth Focus Fund and the
Natural Resources Focus Fund each may also write put options on securities or
securities indices. When the Fund writes a put option, in return for an option
premium the Fund gives another party the right to sell to the Fund a specified
security at the exercise price on or before the expiration date, in the case of
an option on a security, or agrees to pay to another party an amount based on
any decline in a specified securities index below a specified level on or before
the expiration date, in the case of an option on a securities index. The Fund
may write put options to earn income, through the receipt of option premiums. In
the event the party to which the Fund has written an option fails to exercise
its rights under the option because the value of the underlying securities is
greater than the exercise price, the Fund will profit by the amount of the
option premium. By writing a put option, however, the Fund will be obligated to
purchase the underlying security at a price that may be higher than the market
value of the security at the time of exercise as long as the put option is
outstanding, in the case of an option on a security, or make a cash payment
reflecting any decline in the index, in the case of an option on an index.
Accordingly, when the Fund writes a put option it is exposed to a risk of loss
in the event the value of the underlying securities falls below the exercise
price, which loss potentially may substantially exceed the amount of option
premium received by the Fund for writing the put option. The Fund will write a
put option on a security or a securities index only if the Fund would be willing
to purchase the security at the exercise price for investment purposes (in the
case of an option on a security) or is writing the put in connection with
trading strategies involving


                                    Annex B-2
<PAGE>   225

combinations of options - for example, the sale and purchase of options with
identical expiration dates on the same security or index but different exercise
prices (a technique called a "spread").

      Each Fund is also authorized to sell call or put options in connection
with closing out call or put options it has previously purchased.

      Other than with respect to closing transactions, a Fund will only write
call or put options that are "covered." A call or put option will be considered
covered if the Fund has segregated assets with respect to such option in the
manner described in "Risk Factors in Options, Futures, and Currency Instruments"
below. A call option will also be considered covered if a Fund owns the
securities it would be required to deliver upon exercise of the option (or, in
the case of option on a securities index, securities which are substantially
correlated with the performance of such index) or owns a call option, warrant or
convertible instrument which is immediately exercisable for, or convertible
into, such security.

      Types of Options. A Fund may engage in transactions in options on
securities or securities indices on exchanges and in the over-the-counter
("OTC") markets. In general, exchange-traded options have standardized exercise
prices and expiration dates and require the parties to post margin against their
obligations, and the performance of the parties' obligations in connection with
such options is guaranteed by the exchange or a related clearing corporation.
OTC options have more flexible terms negotiated between the buyer and the
seller, but generally do not require the parties to post margin and are subject
to greater risk of counterparty default. See "Additional Risk Factors of OTC
Transactions" below.

Futures

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Global Utility Focus Fund, the Index 500 Fund,
the International Equity Focus Fund, the Global Growth Focus Fund and the
Natural Resources Focus Fund may each engage in transactions in futures and
options thereon. Futures are standardized, exchange-traded contracts which
obligate a purchaser to take delivery, and a seller to make delivery, of a
specific amount of a commodity at a specified future date at a specified price.
No price is paid upon entering into a futures contract. Rather, upon purchasing
or selling a futures contract the Fund is required to deposit collateral
("margin") equal to a percentage (generally less than 10%) of the contract
value. Each day thereafter until the futures position is closed, the Fund will
pay additional margin representing any loss experienced as a result of the
futures position the prior day or be entitled to a payment representing any
profit experienced as a result of the futures position the prior day.

      The sale of a futures contract limits a Fund's risk of loss through a
decline in the market value of portfolio holdings correlated with the futures
contract prior to the futures contract's expiration date. In the event the
market value of the portfolio holdings correlated with the futures contract
increases rather than decreases, however, the Fund will realize a loss on the
futures position and a lower return on the portfolio holdings than would have
been realized without the purchase of the futures contract.

      The purchase of a futures contract may protect a Fund from having to pay
more for securities as a consequence of increases in the market value for such
securities during a period when the Fund was attempting to identify specific
securities in which to invest in a market the Fund believes to be attractive. In
the event that such securities decline in value or the Fund determines not to
complete an anticipatory hedge transaction relating to a futures contract,
however, the Fund may realize a loss relating to the futures position.

      A Fund will limit transactions in futures and options on futures to
financial futures contracts (i.e., contracts for which the underlying commodity
is a currency or securities or interest rate index) purchased or sold for
hedging purposes (including anticipatory hedges). Each Fund will further limit
transactions in futures and options on futures to the extent necessary to
prevent the Fund from being deemed a "commodity pool" under regulations of the
Commodity Futures Trading Commission.


                                    Annex B-3

Foreign Exchange Transactions

      The Developing Capital Markets Focus Fund, the Global Bond Focus Fund, the
Global Strategy Focus Fund, the Global Utility Focus Fund, the International
Equity Focus Fund, the Natural Resources Focus Fund, the Global Growth Focus
Fund, the Capital Focus Fund and the Quality Equity Fund may engage in spot and
forward foreign exchange transactions and currency swaps, purchase and sell
options on currencies and purchase and sell currency futures and related options
thereon (collectively, "Currency Instruments") for purposes of hedging against
the decline in the value of currencies in which its portfolio holdings are
denominated against the US dollar.

      Forward foreign exchange transactions are OTC contracts to purchase or
sell a specified amount of a specified currency or multinational currency unit
at a price and future date set at the time of the contract. Spot foreign
exchange transactions are similar but require current, rather than future,
settlement. A Fund will enter into foreign exchange transactions only for
purposes of hedging either a specific transaction or a portfolio position. A
Fund may enter into a foreign exchange transaction for purposes of hedging a
specific transaction by, for example, purchasing a currency needed to settle a
security transaction or selling a currency in which the Fund has received or
anticipates receiving a dividend or distribution. A Fund may enter into a
foreign exchange transaction for purposes of hedging a portfolio position by
selling forward a currency in which a portfolio position of the Fund is
denominated or by purchasing a currency in which the Fund anticipates acquiring
a portfolio position in the near future. A Fund may also hedge portfolio
positions through currency swaps, which are transactions in which one currency
is simultaneously bought for a second currency on a spot basis and sold for the
second currency on a forward basis.

      The Funds authorized to engage in Currency Instrument transactions may
also hedge against the decline in the value of a currency against the US dollar
through use of currency futures or options thereon. Currency futures are similar
to forward foreign exchange transactions except that futures are standardized
exchange-traded contracts. See "Futures" above.

      The Funds authorized to engage in Currency Instrument transactions may
also hedge against the decline in the value of a currency against the US dollar
through the use of currency options. Currency options are similar to options on
securities, but in consideration for an option premium the writer of a currency
option is obligated to sell (in the case of a call option) or purchase (in the
case of a put option) a specified amount of a specified currency on or before
the expiration date for a specified amount of another currency. The Fund may
engage in transactions in options on currencies either on exchanges or OTC
markets. See "Types of Options" above and "Additional Risk Factors of OTC
Transactions" below.

      No Fund will speculate in Currency Instruments. Accordingly, a Fund will
not hedge a currency in excess of the aggregate market value of the securities
which it owns (including receivables for unsettled securities sales), or has
committed to or anticipates purchasing, which are denominated in such currency.
A Fund may, however, hedge a currency by entering into a transaction in a
Currency Instrument denominated in a currency other than the currency being
hedged (a "cross-hedge"). The Fund will only enter into a cross-hedge if the
Investment Adviser believes that (i) there is a demonstrable high correlation
between the currency in which the cross-hedge is denominated and the currency
being hedged, and (ii) executing a cross-hedge through the currency in which the
cross-hedge is denominated will be significantly more cost-effective or provide
substantially greater liquidity than executing a similar hedging transaction by
means of the currency being hedged.

      Risk Factors in Hedging Foreign Currency Risks. While a Fund's use of
Currency Instruments to effect hedging strategies is intended to reduce the
volatility of the net asset value of the Fund's shares, the net asset value of
the Fund's shares will fluctuate. Moreover, although Currency Instruments will
be used with the intention of hedging against adverse currency movements,
transactions in Currency Instruments involve the risk that anticipated currency
movements will not be accurately predicted and that the Fund's hedging
strategies will be ineffective. To the extent that a Fund hedges against
anticipated currency movements which do not occur, the Fund may realize losses,
and decrease its total return, as the result of its hedging transactions.
Furthermore, a Fund will only engage in hedging activities from time to time and
may not be engaging in hedging activities when movements in currency exchange
rates occur. It may not be possible for a Fund to hedge against currency
exchange rate movements, even


                                    Annex B-4
<PAGE>   227

if correctly anticipated, in the event that (i) the currency exchange rate
movement is so generally anticipated that the Fund is not able to enter into a
hedging transaction at an effective price, or (ii) the currency exchange rate
movement relates to a market with respect to which Currency Instruments are not
available (such as certain developing markets) and it is not possible to engage
in effective foreign currency hedging.

Risk Factors in Options, Futures, and Currency Instruments

      Use of Strategic Instruments for hedging purposes involves the risk of
imperfect correlation in movements in the value of the Strategic Instruments and
the value of the instruments being hedged. If the value of the Strategic
Instruments moves more or less than the value of the hedged instruments a Fund
will experience a gain or loss which will not be completely offset by movements
in the value of the hedged instruments.

      Each Fund intends to enter into transactions involving Strategic
Instruments only if there appears to be a liquid secondary market for such
instruments or, in the case of illiquid instruments traded in OTC transactions,
such instruments satisfy the criteria set forth below under "Additional Risk
Factors of OTC Transactions." However, there can be no assurance that, at any
specific time, either a liquid secondary market will exist for a Strategic
Instrument or the Fund will otherwise be able to sell such instrument at an
acceptable price. It may therefore not be possible to close a position in a
Strategic Instrument without incurring substantial losses, if at all.

      Certain transactions in Strategic Instruments (e.g., forward foreign
exchange transactions, futures transactions, sales of put options) may expose a
Fund to potential losses which exceed the amount originally invested by the Fund
in such instruments. When a Fund engages in such a transaction, the Fund will
deposit in a segregated account at its custodian liquid securities with a value
at least equal to the Fund's exposure, on a mark-to-market basis, to the
transaction (as calculated pursuant to requirements of the Securities and
Exchange Commission). Such segregation will ensure that the Fund has assets
available to satisfy its obligations with respect to the transaction, but will
not limit the Fund's exposure to loss.

Additional Risk Factors of OTC Transactions; Limitations on the Use of OTC
Strategic Instruments

      Certain Strategic Instruments traded in OTC markets, including indexed
securities and OTC options, may be substantially less liquid than other
instruments in which a Fund may invest. The absence of liquidity may make it
difficult or impossible for the Fund to sell such instruments promptly at an
acceptable price. The absence of liquidity may also make it more difficult for
the Fund to ascertain a market value for such instruments. A Fund will therefore
acquire illiquid OTC instruments (i) if the agreement pursuant to which the
instrument is purchased contains a formula price at which the instrument may be
terminated or sold, or (ii) for which the Investment Adviser anticipates the
Fund can receive on each business day at least two independent bids or offers,
unless a quotation from only one dealer is available, in which case that
dealer's quotation may be used.

      The staff of the Securities and Exchange Commission has taken the position
that purchased OTC options and the assets underlying written OTC options are
illiquid securities. Each Fund has therefore adopted an investment policy
pursuant to which it will not purchase or sell OTC options (including OTC
options on futures contracts) if, as a result of such transactions, the sum of
the market value of OTC options currently outstanding which are held by the
Fund, the market value of the securities underlying OTC call options currently
outstanding which have been sold by the Fund and margin deposits on the Fund's
outstanding OTC options exceeds 15% of the total assets of the Fund, taken at
market value, together with all other assets of the Fund which are deemed to be
illiquid or are otherwise not readily marketable. However, if an OTC option is
sold by the Fund to a dealer in U.S. government securities recognized as a
"primary dealer" by the Federal Reserve Bank of New York and the Fund has the
unconditional contractual right to repurchase such OTC option at a predetermined
price, then the Fund will treat as illiquid such amount of the underlying
securities as is equal to the repurchase price less the amount by which the
option is "in-the-money" (i.e., current market value of the underlying security
minus the option's exercise price).

      Because Strategic Instruments traded in OTC markets are not guaranteed by
an exchange or clearing corporation and generally do not require payment of
margin to the extent that a Fund has unrealized gains in such instruments or has
deposited collateral with its counterparty, the Fund is at risk that its
counterparty will become


                                    Annex B-5
<PAGE>   228

bankrupt or otherwise fail to honor its obligations. A Fund will attempt to
minimize the risk that a counterparty will become bankrupt or otherwise fail to
honor its obligations by engaging in transactions in Strategic Instruments
traded in OTC markets only with financial institutions which have substantial
capital or which have provided the Fund with a third-party guaranty or other
credit enhancement.

Additional Limitations on the Use of Strategic Instruments

      No Fund may use any Strategic Instrument to gain exposure to an asset or
class of assets that it would be prohibited by its investment restrictions from
purchasing directly, except that the Natural Resources Focus Fund may acquire
securities indexed to a precious metal or other natural resource index.

                       INVESTMENT OBJECTIVES AND POLICIES

      The investment objectives and certain investment policies of the Funds are
as follows: The Domestic Money Market Fund seeks preservation of capital,
liquidity and the highest possible current income consistent with the foregoing
objectives by investing in short-term domestic money market securities. The
Reserve Assets Fund seeks the preservation of capital, liquidity and the highest
possible current income consistent with the foregoing objectives by investing in
short-term money market securities. The Prime Bond Fund seeks to attain as high
a level of current income as is consistent with prudent investment management,
and as a secondary objective, capital appreciation when consistent with the
foregoing objective, by investing primarily in long-term corporate bonds rated A
or better by either Moody's Investors Service, Inc. ("Moody's") or Standard &
Poor's Rating Group ("Standard & Poor's"). The High Current Income Fund seeks to
attain as high a level of current income as is consistent with its investment
policies and prudent investment management, and as a secondary objective,
capital appreciation when consistent with the foregoing objective; the Fund
invests principally in fixed-income securities which are rated in the lower
rating categories of the established rating services or in unrated securities of
comparable quality. The Quality Equity Fund seeks to attain the highest total
investment return consistent with prudent risk; the Fund uses a fully managed
investment policy utilizing equity securities, primarily common stocks of
large-capitalization companies, as well as investment grade debt and convertible
securities. The Special Value Focus Fund seeks to attain long-term capital
growth by investing primarily in common shares, of small companies and of
emerging growth companies regardless of size. The Natural Resources Focus Fund
seeks to attain long-term growth of capital and the protection of the purchasing
power of shareholders' capital by investing primarily in equity securities of
domestic and foreign companies with substantial natural resource assets. The
American Balanced Fund seeks a level of current income and a degree of stability
of principal not normally available from an investment solely in equity
securities and the opportunity for capital appreciation greater than normally
available from an investment solely in debt securities by investing in a
balanced portfolio of fixed income and equity securities. The Global Strategy
Focus Fund seeks high total investment return by investing primarily in a
portfolio of equity and fixed income securities of U.S. and foreign issuers. The
Basic Value Focus Fund seeks to attain capital appreciation and, secondarily,
income by investing in securities, primarily equities, that management of the
Fund believes are undervalued and therefore represent basic investment value.
The Global Bond Focus Fund seeks to attain high total investment return by
investing in a global portfolio of fixed income securities denominated in
various currencies, including multinational currency units. The Global Utility
Focus Fund seeks to attain capital appreciation and current income through
investment of at least 65% of its total assets in equity and debt securities
issued by domestic and foreign companies which are, in the opinion of the
Investment Adviser, primarily engaged in the ownership or operation of
facilities used to generate, transmit or distribute electricity,
telecommunications, gas or water. The International Equity Focus Fund seeks to
attain capital appreciation and, secondarily, income, through investment in
securities, principally equities, of issuers in countries other than the United
States. The Developing Capital Markets Focus Fund seeks long-term capital
appreciation through investment in securities, principally equities, of issuers
in countries having smaller capital markets. The Government Bond Fund seeks the
highest possible current income consistent with the protection of capital
afforded by investing in debt securities issued or guaranteed by the United
States Government, its agencies or instrumentalities. The Index 500 Fund seeks
to provide investment results that, before expenses, correspond to the aggregate
price and yield performance of Standard & Poor's 500 Composite Stock Price Index
(the "S&P 500 Index"). The Global Growth Focus Fund seeks long-term growth of
capital by investing in a diversified portfolio of equity securities of issuers
located in various foreign countries and the United States with a particular
emphasis on companies that have exhibited above-average growth rates in
earnings. The Merrill Lynch Capital Focus Fund seeks to achieve the highest
total investment return consistent with prudent risk through a fully managed
investment policy utilizing equity, debt (including money market) and
convertible securities.

      Investors are referred to "Investment Objectives and Policies" in each
Fund's Prospectus for a more complete discussion of the investment objectives
and policies of the Company.

                             INVESTMENT RESTRICTIONS

      The Company has adopted the following fundamental and non-fundamental
restrictions and policies relating to the investment of the assets of the Funds
and their activities. The fundamental policies set forth below may not


                                        3
<PAGE>   232

be changed without the approval of the holders of a majority of the outstanding
voting shares of each Fund affected (which for this purpose and under the
Investment Company Act of 1940 means the lesser of (i) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares of the
affected Fund are represented or (ii) more than 50% of the outstanding shares of
the affected Fund).

Restrictions Applicable to the Domestic Money Market Fund

      The Domestic Money Market Fund may not purchase any security other than
money market and other securities described under "Investment Objectives and
Policies" in the Domestic Money Market Fund's Prospectus. In addition, the
Domestic Money Market Fund may not purchase securities of foreign issuers
(including Eurodollar and Yankeedollar obligations). In addition, the Domestic
Money Market Fund may not:

            (1) invest more than 10% of its total assets (taken at market value
      at the time of each investment) in the securities (other than U.S.
      Government or government agency securities) of any one issuer (including
      repurchase agreements with any one bank) except that up to 25% of the
      value of the Fund's total assets may be invested without regard to such
      10% limitation.

            (2) alone, or together with any other Fund or Funds, make
      investments for the purpose of exercising control or management.

            (3) purchase securities of other investment companies, except in
      connection with a merger, consolidation, acquisition or reorganization.

            (4) purchase or sell interests in oil, gas or other mineral
      exploration or development programs, commodities, commodity contracts or
      real estate, except that the Fund may invest in securities secured by real
      estate or interests therein or securities issued by companies which invest
      in real estate or interest therein.

            (5) purchase any securities on margin except that the Company may
      obtain such short-term credit as may be necessary for the clearance of
      purchases and sales of portfolio securities.

            (6) make short sales of securities or maintain a short position or
      write, purchase or sell puts, calls, straddles, spreads or combination
      thereof.

            (7) make loans to other persons; provided that the Fund may purchase
      money market securities or enter into repurchase agreements; lend
      securities owned or held by it pursuant to (8) below; and provided further
      that for purposes of this restriction the acquisition of a portion of an
      issue of publicly distributed bonds, debentures or other corporate debt
      securities or of government obligations, short-term commercial paper,
      certificates of deposit and bankers' acceptances shall not be deemed the
      making of a loan.

            (8) lend its portfolio securities in excess of 20% of its total
      assets, taken at market value at the time of the loan, provided that such
      loans are made according to the guidelines set forth below and the
      guidelines of the Securities and Exchange Commission and the Company's
      Board of Directors, including maintaining collateral from the borrower
      equal at all times to the current market value of the securities loaned.

            (9) borrow amounts in excess of 20% of its total assets, taken at
      market value, and then only from banks as a temporary measure for
      extraordinary or emergency purposes. The borrowing provisions shall not
      apply to reverse repurchase agreements. Usually only "leveraged"
      investment companies may borrow in excess of 5% of their assets; however,
      the Fund will not borrow to increase income but only to meet redemption
      requests which might otherwise require untimely dispositions of portfolio
      securities. The Fund will not purchase securities while borrowings are
      outstanding.


                                        4
<PAGE>   233

            (10) mortgage, pledge, hypothecate or in any manner transfer (except
      as provided in (8) above), as security for indebtedness, any securities
      owned or held by the Fund except as may be necessary in connection with
      borrowings mentioned in (9) above, and then such mortgaging, pledging or
      hypothecating may not exceed 25% of the Fund's total assets, taken at
      market value at the time thereof. Although the Fund has the authority to
      mortgage, pledge or hypothecate more than 10% of its total assets under
      this investment restriction (10), as a matter of operating policy, the
      Fund will not mortgage, pledge or hypothecate in excess of 10% of total
      net assets.

            (11) act as an underwriter of securities, except insofar as the Fund
      may be deemed an underwriter under the Securities Act of 1933 in selling
      portfolio securities.

            (12) purchase, either alone or together with any other Fund or
      Funds, more than 10% of the outstanding securities of an issuer except
      that such restriction does not apply to U.S. Government or government
      agency securities, bank money instruments or repurchase agreements.

            (13) invest in securities (except for repurchase agreements or
      variable amount master notes) with legal or contractual restrictions on
      resale or for which no readily available market exists or in securities of
      issuers (other than issuers of government agency securities) having a
      record, together with predecessors, of less than three years of continuous
      operation if, regarding all such securities, more than 10% of its total
      assets (taken at market value) would be invested in such securities.

            (14) enter into repurchase agreements if, as a result thereof, more
      than 10% of the Fund's total assets (taken at market value at the time of
      each investment) would be subject to repurchase agreements maturing in
      more than seven days.

            (15) enter into reverse repurchase agreements if, as a result
      thereof, the Fund's obligations with respect to reverse repurchase
      agreements would exceed one-third of the Fund's net assets (defined to be
      total assets, taken at market value, less liabilities other than reverse
      repurchase agreements).

            (16) invest more than 25% of its total assets (taken at market value
      at the time of each investment) in the securities of issuers in any
      particular industry (other than U.S. Government securities, government
      agency securities or bank money instruments).

Restrictions Applicable to the Reserve Assets Fund

      The Reserve Assets Fund may not purchase any security other than money
market and other securities described under "Investment Objectives and Policies"
in the Prospectus for the Reserve Assets Fund. In addition, the Reserve Assets
Fund may not:

            (1) invest more than 10% of its total assets (taken at market value
      at the time of each investment) in the securities (other than U.S.
      Government or government agency securities) of any one issuer (including
      repurchase agreements with any one bank) except that up to 25% of the
      value of the Fund's total assets may be invested without regard to such
      10% limitation.

            (2) alone, or together with any other Fund or Funds, make
      investments for the purpose of exercising control or management.

            (3) purchase securities of other investment companies, except in
      connection with a merger, consolidation, acquisition or reorganization.

            (4) purchase or sell interests in oil, gas or other mineral
      exploration or development programs, commodities, commodity contracts or
      real estate, except that the Fund may invest in securities secured by real
      estate or interests therein or securities issued by companies which invest
      in real estate or interest therein.

      obtain such short-term credit as may be necessary for the clearance of

      write, purchase or sell puts, calls, straddles, spreads or combinations

      money market securities or enter into repurchase agreements; lend
      securities owned or held by it pursuant to (8) below; and provided further
      that for purposes of this restriction the acquisition of a portion of an
      issue of publicly-distributed bonds, debentures or other corporate debt
      securities or of government obligations, short-term commercial paper,
      certificates of deposit and bankers' acceptances shall not be deemed the
      making of a loan.

            (8) lend its portfolio securities in excess of 20% of its total
      assets, taken at market value at the time of the loan, provided that such
      loans are made according to the guidelines set forth below and the
      guidelines of the Securities and Exchange Commission and the Company's
      Board of Directors, including maintaining collateral from the borrower
      equal at all times to the current market value of the securities loaned.

            (9) borrow amounts in excess of 20% of its total assets, taken at
      market value and then only from banks as a temporary measure for
      extraordinary or emergency purposes. The borrowing provisions shall not

      investment companies may borrow in excess of 5% of their assets; however,
      the Fund will not borrow to increase income but only to meet redemption
      requests which might otherwise require untimely dispositions of portfolio
      securities. The Fund will not purchase securities while borrowings are
      outstanding.

            (10) mortgage, pledge, hypothecate or in any manner transfer (except
      as provided in (8) above), as security for indebtedness, any securities

      hypothecating may not exceed 25% of the Fund's total assets, taken at
      market value at the time thereof. As a matter of operating policy, the
      Fund will not mortgage, pledge or hypothecate in excess of 10% of total
      net assets.

            (11) act as an underwriter of securities, except insofar as the Fund
      may be deemed an underwriter under the Securities Act of 1933 in selling
      portfolio securities.

            (12) purchase, either alone or together with any other Fund or
      Funds, more than 10% of the outstanding securities of an issuer except
      that such restriction does not apply to U.S. Government or government
      agency securities, bank money instruments or repurchase agreements.

            (13) invest in securities (except for repurchase agreements or

      repurchase agreements).

<PAGE>   235

            (16) invest more than 25% of its total assets (taken at market value
      at the time of each investment) in the securities of issuers in any
      particular industry (other than U.S. Government securities, government
      agency securities or bank money instruments).

Restrictions Applicable to each of the Funds (except the Domestic Money Market
Fund and the Reserve Assets Fund)

      Under the fundamental investment restrictions, each of the Funds (unless
noted otherwise below) may not:

            1. Make any investment inconsistent with the Fund's classification
      as a diversified company under the Investment Company Act. (3)

            2. Invest more than 25% of its assets, taken at market value, in the
      securities of issuers in any particular industry (excluding the U.S.
      Government and its agencies and instrumentalities). (4)

            3. Make investments for the purpose of exercising control or
      management. (5)

            4. Purchase or sell real estate, except that the Fund may invest in
      securities directly or indirectly secured by real estate or interests
      therein or issued by companies which invest in real estate or interests
      therein.

            5. Make loans to other persons, except that the acquisition of
      bonds, debentures or other corporate debt securities and investment in
      government obligations, commercial paper, pass-through instruments,
      certificates of deposit, bankers acceptances, repurchase agreements or any
      similar instruments shall not be deemed to be the making of a loan, and
      except further that the Fund may lend its portfolio securities, provided
      that the lending of portfolio securities may be made only in accordance
      with applicable law and the guidelines set forth in the Prospectus and
      Statement of Additional Information, as they may be amended from time to
      time.

            6. Issue senior securities to the extent such issuance would violate
      applicable law.

            7. Borrow money, except that (i) the Fund may borrow from banks (as
      defined in the Investment Company Act) in amounts up to 33 1/3% of its
      total assets (including the amount borrowed), (ii) the Fund may borrow up
      to an additional 5% of its total assets for temporary purposes, (iii) the
      Fund may obtain such short-term credit as may be necessary for the
      clearance of purchases and sales of portfolio securities and (iv) the Fund
      may purchase securities on margin to the extent permitted by applicable
      law.

- ----------

(3) The Developing Capital Markets Focus, Global Bond Focus, Global Strategy
    Focus, Index 500, and Natural Resource Focus Funds are classified as
    non-diversified investment companies under the Investment Company Act, and
    therefore this restriction is not applicable to those Funds.

(4) For purposes of this restriction, states, municipalities and their political
    subdivisions are not considered to be part of any industry, and utilities
    will be divided according to their services; for example, gas, gas
    transmission, electricity, telecommunications and water each will be
    considered a separate industry for purposes of this restriction. In
    addition, this restriction will not restrict (i) the Global Utility Focus
    Fund, under normal circumstances, from investing 65% or more of its total
    assets in equity and debt securities issued by domestic and foreign
    companies in the utilities industries (i.e., electricity,
    telecommunications, gas or water), and (ii) the Natural Resources Focus Fund
    from investing greater than 25% of its assets in gold-related companies.

(5) In the case of the Global Growth Focus Fund, investments in wholly-owned
    investment entities created under the laws of certain countries will not be
    deemed to be the making of investments for the purpose of exercising control
    or management.

      The Fund may not pledge its assets other than to secure such borrowings
      or, to the extent permitted by the Fund's investment policies as set forth
      in the Prospectus and Statement of Additional Information, as they may be
      amended from time to time, in connection with hedging transactions, short
      sales, when-issued and forward commitment transactions and similar
      investment strategies.

            8. Underwrite securities of other issuers except insofar as the Fund
      technically may be deemed an underwriter under the Securities Act of 1933
      in selling portfolio securities.

            9. Purchase or sell commodities or contracts on commodities, except
      to the extent the Fund may do so in accordance with applicable law and the
      Prospectus and Statement of Additional Information, as they may be amended
      from time to time, and without registering as a commodity pool operator
      under the Commodity Exchange Act.

      Under the non-fundamental investment restrictions, each of the Funds
      (unless noted otherwise below) may not:

            a. Purchase securities of other investment companies, except to the
      extent such purchases are permitted by applicable law. As a matter of
      policy, however, the Fund will not purchase shares of any registered
      open-end investment company or registered unit investment trust, in
      reliance on Section 12(d)(1)(F) or (G) (the "fund of funds" provisions) of
      the Investment Company Act, at any time its shares are owned by another
      investment company that is part of the same group of investment companies
      as the Fund.

            b. Engage in short sales of securities or maintain a short position
      except to the extent permitted by applicable law. The Fund does not
      currently intend to engage in short sales or maintain a short position,
      except for short sales "against the box." (6)

            c. Invest in securities which cannot be readily resold because of
      legal or contractual restrictions or which cannot otherwise be marketed,
      redeemed or put to the issuer or a third party, if at the time of
      acquisition more than 15% of its total assets would be invested in such
      securities. This restriction shall not apply to securities which mature
      within seven days or securities which the Board of Directors has otherwise
      determined to be liquid pursuant to applicable law. Securities purchased
      in accordance with Rule 144A under the Securities Act and determined to be
      liquid by the Board of Directors of the Company are not subject to the
      limitations set forth in this investment restriction.

            d. Invest in warrants if, at the time of acquisition, its
      investments in warrants, valued at the lower of cost or market value,
      would exceed 5% of the Fund's total assets; included within such
      limitation, but not to exceed 2% of the Fund's total assets, are warrants
      which are not listed on the New York Stock Exchange or American Stock
      Exchange or a major foreign exchange. For purposes of this restriction,
      warrants acquired by the Fund in units or attached to securities may be
      deemed to be without value. (7)

            e. Invest in securities of companies having a record, together with
      predecessors, of less than three years of continuous operation, except to
      the extent permitted under applicable law. This restriction shall not
      apply to mortgage-backed securities, asset-backed securities or
      obligations issued or guaranteed by the U.S. Government, its agencies or
      instrumentalities. (8)

            f. Purchase or retain the securities of any issuer, if those
      individual officers and directors of the Company, the officers and general
      partner of the Investment Adviser, the directors of such general partner
      or the officers and directors of any subsidiary thereof each owning
      beneficially more than one-half of one percent of the securities of such
      issuer own in the aggregate more than 5% of the securities of such
      issuer. (9)

            g. Invest in real estate limited partnership interests or interests
      in oil, gas or other mineral leases, or exploration or development
      programs, except that the Fund may invest in securities issued by
      companies that engage in oil, gas or other mineral exploration or
      development activities. (10) 

            h. Write, purchase or sell puts, calls, straddles, spreads or
      combinations thereof, except to the extent permitted in the Prospectus and
      Statement of Additional Information, as they may be amended from time to
      time.

            i. Notwithstanding fundamental investment restriction number 7
      above, borrow amounts in excess of 5% (20% in the case of the Developing
      Capital Markets Focus and Global Bond Focus Funds 10% in the case of the
      Global Strategy Focus, Government Bond, International Equity Focus and
      Natural Resources Focus Funds, and 33 1/3% in the case of the Global

            j. Pledge greater than 10% (20% in the case of the Developing
      Capital Markets Focus Fund) of its total assets, taken at market value at
      the time of the pledge. For the purpose of this restriction, collateral
      arrangements with respect to (i) transactions in options, foreign currency
      contracts, futures contracts and options on futures contracts and (ii)
      initial and variation margin are not deemed to be a pledge of assets. (12)

            k. Lend its portfolio securities in excess of 20% of its total
      assets (33 1/3% in the case of the Global Growth Focus Fund), taken at
      market value at the time of the loan, provided however that the Quality
      Equity Fund may only make loans to New York Stock Exchange Member firms,
      other brokerage firms having net capital of at least $10 million and
      financial institutions, such as registered investment companies, banks and
      insurance companies, having at least $10 million in capital and surplus.

            l. In the case of the Global Utility Focus Fund only, invest less
      than 65% of its total assets in equity and debt securities issued by
      domestic and foreign companies in the utilities industries, except during
      temporary defensive periods.

    not purchase securities while borrowings are outstanding, except, in the
    case of the Developing Capital Markets Focus Fund, (a) to honor prior
    commitments or (b) to exercise subscription rights where outstanding
    borrowings have been obtained exclusively for settlements of other
    securities transactions. The Global Bond Focus, Global Utility Focus,
    International Equity Focus and Global Growth Focus Funds will not purchase
    securities while borrowings in excess of 5% of its total assets are
    outstanding.

            m. In the case of each of the American Balanced Fund, the Basic
      Value Focus Fund, the Special Value Focus Fund, the High Current Income
      Fund, the Prime Bond Fund and the Quality Equity Fund, invest in the
      securities of foreign issuers except that each such Fund (except the
      American Balanced Fund) may invest in securities of foreign issuers if at
      the time of acquisition no more than 10% (25% in the case of the Quality
      Equity Fund) of its total assets, taken at market value at the time of the
      investment, would be invested in such securities. Consistent with the
      general policy of the Securities and Exchange Commission, the nationality
      or domicile of an issuer for determination of foreign issuer status may be
      (i) the country under whose laws the issuer is organized, (ii) the country
      in which the issuer's securities are principally traded, or (iii) a
      country in which the issuer derives a significant proportion (at least
      50%) of its revenues or profits from goods produced or sold, investments
      made, or services performed in the country, or in which at least 50% of
      the assets of the issuer are situated. See "Other Portfolio
      Strategies-Foreign Securities" in the Prospectus.(13)

Over-the-Counter Options

      The staff of the Securities and Exchange Commission has taken the position
that purchased over-the-counter ("OTC") options and the assets used as cover for
written OTC options are illiquid securities. Therefore, the Company has adopted
an investment policy pursuant to which it will not purchase or sell OTC options
if, as a result of such transactions, the sum of the market value of OTC options
currently outstanding which are held by a Fund, the market value of the
underlying securities covered by OTC call options currently outstanding which
were sold by the Fund and margin deposits on the Fund's existing OTC options on
futures contracts exceeds 15% of the total assets of the Fund, taken at market
value, together with all other assets of the Fund which are illiquid or are
otherwise not readily marketable. However, if an OTC option is sold by a Fund to
a primary U.S. Government securities dealer recognized by the Federal Reserve
Bank of New York and if the Fund has the unconditional contractual right to
repurchase such OTC option from the dealer at a predetermined price, then the
Fund will treat as illiquid such amount of the underlying securities equal to
the repurchase price less the amount by which the option is "in-the-money"
(i.e., current market value of the underlying securities minus the option's
strike price). The repurchase price with the primary dealers is typically a
formula price which is generally based on a multiple of the premium received for
the option, plus the amount by which the option is "in-the-money." This policy
as to OTC options is not a fundamental policy of any Fund and may be amended by
the Directors of the Company without the approval of the Company's shareholders.
However, the Company will not change or modify this policy prior to the change
or modification by the Commission staff of its position.

Restricted Securities

      From time to time a Fund may invest in securities the disposition of which
is subject to legal restrictions, such as restrictions imposed by the Securities
Act of 1933 (the "Securities Act") on the resale of securities acquired in
private placements. If registration of such securities under the Securities Act
is required, such registration may not be readily accomplished and if such
securities may be sold without registration, such resale may be permissible only
in limited quantities. In either event, a Fund may not be able to sell its
restricted securities at a time which, in the judgment of the Investment
Adviser, would be most opportune.

      Each of the Funds is subject to  limitations  on the amount of  securities
which  are  illiquid,  because  of  restrictions  under  the  Securities  Act or
otherwise, they may purchase. Each Fund may, however, purchase without regard to
that limitation securities that are not registered under the Securities Act, but
that can be offered and sold to "qualified institutional buyers" under Rule 144A
under the Securities Act, provided that the Company's Board

- --------

(13)Notwithstanding this restriction, each of the Prime Bond Fund and the High
    Current Income Fund may invest up to 25% of its total assets in securities
    (i) issued, assumed or guaranteed by foreign governments, or political
    subdivisions or instrumentalities thereof, (ii) assumed or guaranteed by
    domestic issuers, including Eurodollar securities or (iii) issued, assumed
    or guaranteed by foreign issuers having a class of securities listed for
    trading on the New York Stock Exchange.


                                       10
<PAGE>   239

of Directors continuously determines, based on the trading markets for the
specific Rule 144A security, that it is liquid. The Board of Directors may adopt
guidelines and delegate to the Investment Adviser the daily function of
determining and monitoring liquidity of restricted securities. The Board has
determined that securities which are freely tradeable in their primary market
offshore should be deemed liquid. The Board, however, will retain sufficient
oversight and be ultimately responsible for the determinations.

      Since it is not possible to predict with assurance exactly how the market
for restricted securities sold and offered under Rule 144A will develop, the
Board of Directors will carefully monitor the Fund's investments in these
securities, focusing on such factors, among others, as valuation, liquidity and
availability of information. This investment practice could have the effect of
increasing the level of illiquidity in a Fund to the extent that qualified
institutional buyers become for a time uninterested in purchasing these
restricted securities.

Portfolio Strategies

      Liquidity. In order to assure that each Fund has sufficient liquidity, as
a matter of operating policy no Fund may invest more than 10% of its net assets,
except that each of the Developing Capital Markets Focus Fund, Global Growth
Focus Fund and Capital Focus Fund may not invest more than 15% of its net assets
in securities for which market disposition is not readily available. Market
disposition may not be readily available for repurchase agreements maturing in
more than seven days and for securities having restrictions on resale.

      Lending of Portfolio Securities. Subject to any applicable investment
restriction above, each Fund may from time to time loan securities from its
portfolio to brokers, dealers and financial institutions and receive collateral
in cash, securities issued or guaranteed by the U.S. Government or, in the case
of the Domestic Money Market and Reserve Assets Fund, cash equivalents which
while the loan is outstanding will be maintained at all times in an amount equal
to at least 100% of the current market value of the loaned securities. Such cash
collateral will be invested in short-term securities, the income from which will
increase the return to the Fund. The Fund will retain all rights of beneficial
ownership as to the loaned portfolio securities, including voting rights and
rights to interest or other distributions, and will have the right to regain
record ownership of loaned securities to exercise such beneficial rights. Such
loans will be terminable at any time. The Fund may pay reasonable finders',
administrative and custodial fees to persons unaffiliated with the Fund in
connection with the arranging of such loans. The dividends, interest and other
distributions received by the Company on loaned securities may, for tax
purposes, be treated as income other than qualified income for the 90% test
discussed under "Dividends, Distributions and Taxes-Federal Income Taxes." The
Company intends to lend portfolio securities only to the extent that such
activity does not jeopardize the Company's qualification as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended.

      Forward Commitments. Securities may be purchased or sold on a delayed
delivery basis or may be purchased on a forward commitment basis by each of the
Company's Funds at fixed purchase terms with periods of up to 180 days between
the commitment and settlement dates. The purchase will be recorded on the date
the purchasing Fund enters into the commitment and the value of security will
thereafter be reflected in the calculation of the Fund's net asset value. The
value of the security on the delivery date may be more or less than its purchase
price. A separate account of the Fund will be established with The Bank of New
York or Brown Brothers Harriman & Co. (for Developing Capital Markets Focus
Fund) (the "Custodian") consisting of cash or liquid securities having a market
value at all times until the delivery date at least equal to the amount of its
commitments in connection with such delayed delivery and purchase transactions.
Although a Fund will generally enter into forward commitments with the intention
of acquiring securities for its portfolio, it may dispose of a commitment prior
to settlement if the Investment Adviser deems it appropriate to do so. There
can, of course, be no assurance that the judgment upon which these techniques
are based will be accurate or that such techniques when applied will be
effective. The Funds will enter into forward commitment arrangements only with
respect to securities in which they may otherwise invest as described under
"Investment Objectives and Policies of the Funds" in the Prospectus.

      Eurodollar and Yankeedollar Obligations. The Reserve Assets Fund (and, for
temporary or defensive purposes, the Natural Resources Focus, Global Strategy
Focus, Global Bond Focus, Global Utility Focus, International Equity Focus,
Developing Capital Markets Focus and the Quality Equity Funds) may invest in


                                       11
<PAGE>   240

obligations issued by foreign branches or subsidiaries of U.S. banks
("Eurodollar" obligations), by U.S. branches or subsidiaries of foreign banks
("Yankeedollar" obligations), or by foreign depository institutions and their
foreign branches and subsidiaries ("foreign bank obligations"). Investment in
such obligations may involve different risks from the risks of investing in
obligations of U.S. banks. Such risks include adverse political and economic
developments, the possible imposition of withholding taxes on interest income
payable on such obligations, the possible seizure or nationalization of foreign
deposits and the possible establishment of exchange controls or other foreign
governmental laws or restrictions which might adversely affect the payment of
principal and interest. Generally the issuers of such obligations are subject to
fewer U.S. regulatory requirements than are applicable to U.S. banks. Foreign
depository institutions and their foreign branches and subsidiaries, and foreign
branches or subsidiaries of U.S. banks, may be subject to less stringent reserve
requirements than U.S. banks. U.S. branches or subsidiaries of foreign banks are
subject to the reserve requirements of the state in which they are located.
There may be less publicly available information about a foreign depository
institution, branch or subsidiary, or a U.S. branch or subsidiary of a foreign
bank, than about a U.S. bank, and such institutions may not be subject to the
same accounting, auditing and financial record keeping standards and
requirements as U.S. banks. Evidence of ownership of Eurodollar and foreign bank
obligations may be held outside of the United States, and a Fund may be subject
to the risks associated with the holding of such property overseas. Eurodollar
and foreign bank obligations of the Fund held overseas will be held by foreign
branches of the Custodian for the Fund or by other U.S. or foreign banks under
subcustodian arrangements complying with the requirements of the Investment
Company Act of 1940.

      The Investment Adviser will consider the above factors in making
investments in Eurodollar, Yankeedollar and foreign bank obligations and will
not knowingly purchase obligations which, at the time of purchase, are subject
to exchange controls or withholding taxes. Generally, the Reserve Assets Fund
will limit its Yankeedollar investments to obligations of banks organized in
Canada, France, Germany, Japan, the Netherlands, Switzerland, the United Kingdom
and other western industrialized nations.

      Standby Commitment Agreements. The High Current Income Fund, Global
Utility Focus Fund, International Equity Focus Fund, Global Growth Focus Fund
and Developing Capital Markets Focus Fund may from time to time enter into
standby commitment agreements. Such agreements commit a Fund, for a stated
period of time, to purchase a stated amount of a fixed income security which may
be issued and sold to the Fund at the option of the issuer. The price and coupon
of the security is fixed at the time of the commitment. At the time of entering
into the agreement the Fund is paid a commitment fee, regardless of whether or
not the security is ultimately issued, which is typically approximately 0.5% of
the aggregate purchase price of the security which the Fund has committed to
purchase. A Fund will enter into such agreements only for the purpose of
investing in the security underlying the commitment at a yield and price which
is considered advantageous to the Fund. A Fund will not enter into a standby
commitment with a remaining term in excess of 45 days and will limit its
investment in such commitments so that the aggregate purchase price of the
securities subject to such commitments, together with the value of portfolio
securities subject to legal restrictions on resale, will not exceed 10% of its
assets taken at the time of acquisition of such commitment or security. A Fund
will at all times maintain a segregated account with its custodian of cash or
liquid securities in an amount equal to the purchase price of the securities
underlying the commitment.

      There can be no assurance that the securities subject to a standby
commitment will be issued and the value of the security, if issued, on the
delivery date may be more or less than its purchase price. Since the issuance of
the security underlying the commitment is at the option of the issuer, a Fund
may bear the risk of a decline in the value of such security and may not benefit
from an appreciation in the value of the security during the commitment period.

      The purchase of a security subject to a standby commitment agreement and
the related commitment fee will be recorded on the date on which the security
can reasonably be expected to be issued and the value of the security will
thereafter be reflected in the calculation of a Fund's net asset value. If the
security is issued, the cost basis of the security will be adjusted by the
amount of the commitment fee. In the event the security is not issued, the
commitment fee will be recorded as income on the expiration date of the standby
commitment.

                        INVESTMENT ADVISORY ARRANGEMENTS

      The Company has entered into seven separate investment advisory agreements
(the "Investment Advisory Agreements") relating to the Funds with Merrill Lynch
Asset Management, L.P. ("MLAM"), the Investment Adviser (the "Investment
Advisor"), a wholly owned subsidiary of Merrill Lynch & Co., Inc. The principal
business address of the Investment Adviser is 800 Scudders Mill Road,
Plainsboro, New Jersey 08536. The Investment Adviser or its affiliate Fund Asset
Management, L.P. ("FAM") FAM currently acts as the investment adviser to over
140 other registered investment companies.

      The principal executive officers and directors of the Investment Adviser
are Arthur Zeikel, President; Terry K. Glenn, Executive Vice President; Robert
W. Crook, Senior Vice President; Linda L. Federici, Senior Vice President;
Vincent R. Giordano, Senior Vice President; Elizabeth Griffin, Senior Vice
President; Norman R. Harvey, Senior Vice President; Michael J. Hennewinkel,
Senior Vice President; Philip L. Kirstein, Senior Vice President, General
Counsel, Director and Secretary; Ronald M. Kloss, Senior Vice President and
Controller; Debra W. Landsman-Yros, Senior Vice President; Richard L. Reller,
Senior Vice President; Stephen M. M. Miller, Senior Vice President; Joseph T.
Monagle, Jr., Senior Vice President; Michael L. Quinn, Senior Vice President;
Gerald M. Richard, Senior Vice President and Treasurer; Gregory Upah, Senior
Vice President; Ronald L. Welburn, Senior Vice President; and Anthony Wiseman,
Senior Vice President.

      Securities held by any Fund may also be held by other funds for which the
Investment Adviser or FAM acts as an adviser or by investment advisory clients
of the Investment Adviser. Because of different investment objectives or other
factors, a particular security may be bought for one or more clients when one or
more clients are selling the same security. If purchases or sales of securities
for any Fund or other funds for which the Investment Adviser or FAM acts as
investment adviser or for their advisory clients arise for consideration at or
about the same time, transactions in such securities will be made, insofar as
feasible, for the respective funds and clients in a manner deemed equitable to
all. To the extent that transactions on behalf of more than one client of the
Investment Adviser or FAM during the same period may increase the demand for
securities being purchased or the supply of securities being sold, there may be
an adverse effect on price.

      Advisory Fee. As compensation for its services to the Company and its
Funds, the Investment Adviser receives a fee from the Company at the end of each
month at an annual rate of 0.75% of the average daily net assets of each of the
Special Value Focus Fund, Global Growth Focus Fund, and International Equity
Focus Fund, 0.65% of the average daily net assets of each of the Natural
Resources Focus Fund and Global Strategy Focus Fund, 0.55% of the average daily
net assets of the American Balanced Fund, 0.50% of the average daily net assets
of the Capital Focus Fund, Domestic Money Market Fund and Government Bond Fund,
0.60% of the average daily net assets of the Basic Value Focus Fund, Global Bond
Focus Fund and Global Utility Focus Fund, 1.00% of the average daily net assets
of the Developing Capital Markets Focus Fund, 0.30% of the average daily net
assets of the Index 500 Fund and at the following annual rates with respect to
the other Funds:

      These fee rates for the Prime Bond Fund and High Current Income Fund are
applied to the average daily net assets of each Fund, with the reduced rates
shown below applicable to portions of each Fund to the extent that the aggregate
of the average daily net assets of the combined Fund exceed $250 million, $300
million, $400 million and $800 million (each such amount being a "breakpoint
level"). The portion of the assets of a Fund to which the rate at each
breakpoint level applies will be determined on a "uniform percentage" basis. The
uniform percentage applicable to a breakpoint level is determined by dividing
the amount of the aggregate of the average daily net assets of the combined Fund
that falls within that breakpoint level by the aggregate of the average daily
net assets of the combined Fund. The amount of the fee for a Fund at each
breakpoint level is determined by multiplying the average daily net assets of
that Fund by the uniform percentage applicable to that breakpoint level and
multiplying the product by the advisory fee rate.

      The Investment Adviser and Merrill Lynch Life Agency, Inc. ("MLLA")
entered into two reimbursement agreements, dated April 30, 1985 and February 11,
1992 and amended effective [DATE] (as so amended, the "Reimbursement
Agreements"), that provide that the expenses paid by each Fund (excluding
interest, taxes, brokerage fees and commissions and extraordinary charges such
as litigation costs, and excluding the distribution fees if any imposed on Class
B shares of such Fund) will be limited to 1.25% of its average net assets. Any
such expenses in excess of this percentage will be reimbursed to the Fund by the
Investment Adviser which, in turn, will be reimbursed by MLLA. The Reimbursement
Agreements may be amended or terminated by the parties thereto upon prior
written notice to the Company. For the fiscal year ended December 31, 1997, the
Investment Adviser earned fees of $30,733,366 and reimbursed $217,067 for the
Developing Capital Markets Focus Fund, and $78,164 for the Government Bond Fund.
Except to the extent required pursuant to the aforementioned agreements, the
Investment Adviser does not intend to reimburse the Global Bond Focus Fund for
such Fund's operating expenses. For the fiscal year ended December 31, 1996, the
Investment Adviser earned fees of $765,718 for the Developing Capital Markets
Focus Fund of which $52,388 was voluntarily waived, $297,926 for the Government
Bond Fund of which $264,214 was voluntarily waived, and $1,638 for the Index 500
Fund, all of which was voluntarily waived. In addition, the Investment Adviser
has also reimbursed the Index 500 Fund $1,651 in additional expenses.

      The Investment Advisory Agreements relating to the Company's Funds, unless
earlier terminated as described below, will continue in effect from year to year
if approved annually (a) by the Board of Directors of the Company or by a
majority of the outstanding shares of the respective Funds, and (b) by a
majority of the directors who are not parties to such contracts or interested
persons (as defined in the Investment Company Act of 1940) of any such party.
The Board of Directors of the Company approved the continuation of the
Investment Advisory Agreements relating to all Funds, other than the Capital
Focus Fund and Global Growth Focus Fund, at


                                       17
<PAGE>   246

a meeting held on March 31, 1997. The Board of Directors of the Company approved
the Investment Advisory Agreement relating to the Capital Focus Fund and Global
Growth Focus Fund at a meeting held on March 31, 1998. The Investment Advisory
Agreements are not assignable and may be terminated without penalty on 60 days'
written notice at the option of either party or by the vote of the shareholders
of the respective Funds.

      The Investment Adviser has entered into a sub-advisory agreement (the
"Sub-Advisory Agreement") with MLAM U.K., an indirect wholly owned subsidiary of
ML & Co., and an affiliate of the Investment Adviser, pursuant to which the
Investment Adviser pays MLAM U.K. a fee for providing investment advisory
services to the Investment Adviser with respect to the Funds in an amount to be
determined from time to time by the Investment Adviser and MLAM U.K. but in no
event in excess of the amount that the Investment Adviser actually receives for
providing services to the Funds pursuant to the Investment Advisory Agreement.

      The Investment Adviser has entered into administrative services agreements
with certain Insurance Companies, including MLLIC and ML of New York, pursuant
to which the Investment Adviser compensates such companies for administrative
responsibilities relating to the Company which are performed by such Insurance
Companies.

      Payment of Expenses. The Investment Advisory Agreements obligate the
Investment Adviser to provide investment advisory services and to pay all
compensation of and furnish office space for officers and employees of the
Company connected with investment and economic research, trading and investment
management of the Funds, as well as the fees of all directors of the Company who
are affiliated persons of Merrill Lynch & Co., Inc. or any of its subsidiaries.
Each Fund will pay all other expenses incurred in its operation, including a
portion of the Company's general administrative expenses allocated on the basis
of the Fund's asset size. Expenses that will be borne directly by the Funds
include redemption expenses, expenses of portfolio transactions, shareholder
servicing costs, expenses of registering the shares under federal and state
securities laws, pricing costs (including the daily calculation of net asset
value), interest, certain taxes, charges of the Custodian and Transfer Agent and
other expenses attributable to a particular Fund. Expenses which will be
allocated on the basis of size of the respective Funds include directors' fees,
legal expenses, state franchise taxes, auditing services, costs of printing
proxies and stock certificates, Securities and Exchange Commission fees,
accounting costs and other expenses properly payable by the Company and
allocable on the basis of size of the respective Funds. Accounting services are
provided for the Company by the Investment Adviser, and the Company reimburses
the Investment Adviser for its costs in connection with such services. For the
fiscal year ended December 31, 1997, the amount of such reimbursement was
$1,157,644. Depending upon the nature of the lawsuit, litigation costs may be
directly applicable to the Funds or allocated on the basis of the size of the
respective Funds. The Board of Directors has determined that this is an
appropriate method of allocation of expenses.

                        DETERMINATION OF NET ASSET VALUE

      As set forth in the Prospectus, since the net investment income of the
Domestic Money Market and Reserve Assets Funds (including realized gains and
losses on its portfolio securities) is declared as a dividend each time the net
income of the Funds are determined (see "Dividends, Distributions and Taxes"),
the net asset value per share of the Funds normally remains at $1.00 per share
immediately after each such determination and dividend declaration. The Board of
Directors of the Company expects that the Domestic Money Market and Reserve
Assets Funds will have a positive net income at the time of each determination.
If for any reason the net income of either Fund is a negative amount (i.e., net
realized and unrealized losses and expenses exceed interest income), that Fund
will reduce the number of its outstanding shares. This reduction will be
effected by having the Separate Accounts of the Insurance Companies
proportionately contribute to the capital of the Fund the necessary shares that
represent the amount of the excess upon such determination. It is anticipated
that the Insurance Companies will agree to such contribution in these
circumstances. Any such contribution will be treated as a negative dividend for
purposes of the Net Investment Factor under the Contracts described in the
Prospectus for the Contracts. See "Dividends, Distributions and Taxes" for a
discussion of the tax effect of such a reduction. This procedure will permit the
net asset value per share of the Domestic Money Market and Reserve Assets Funds
to be maintained at a constant value of $1.00 per share.


                                       18
<PAGE>   247

      If in the view of the Board of Directors of the Company it is inadvisable
to continue the practice of maintaining the net asset value of the Domestic
Money Market and Reserve Assets Funds at $1.00 per share, the Board of Directors
of the Company reserves the right to alter the procedure. The Company will
notify the Insurance Companies of any such alteration.

      Each of the International Equity Focus Fund, Global Utility Focus Fund,
Global Bond Focus Fund, Global Growth Focus Fund, and Developing Capital Markets
Focus Fund may invest a substantial portion of its assets in foreign securities
which are traded on days on which such Fund's net asset value is not computed.
On any such day, shares of such a Fund may not be purchased or redeemed since
shares of a Fund may only be purchased or redeemed on days on which the Fund's
net asset value is computed.

      As set forth in the Prospectus, securities held by the Domestic Money
Market and Reserve Assets Funds with a remaining maturity of 60 days or less are
valued on an amortized cost basis, unless particular circumstances dictate
otherwise. Under this method of valuation, the security is initially valued at
cost on the date of purchase (or in the case of securities purchased with more
than 60 days remaining to maturity, the market value on the 61st day prior to
maturity); and thereafter the Domestic Money Market and Reserve Assets Funds
assume a constant proportionate amortization in value until maturity of any
discount or premium, regardless of the impact of fluctuating interest rates on
the market value of the security. For purposes of this method of valuation, the
maturity of a variable rate certificate of deposit is deemed to be the next
coupon date on which the interest rate is to be adjusted. If, due to the
impairment of the creditworthiness of the issuer of a security held by either
Fund or to other factors with respect to such security, the fair value of such
security is not fairly reflected through the amortized cost method of valuation,
such security will be valued at fair value as determined in good faith by the
Board of Directors.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

      If the securities in which a particular Fund of the Company invests are
traded primarily in the over-the-counter market, where possible, the Fund will
deal directly with the dealers who make a market in the securities involved,
except in those circumstances where better prices and execution are available
elsewhere. Such dealers usually are acting as principals for their own account.
On occasions, securities may be purchased directly from the issuer. Bonds and
money market securities are generally traded on a net basis and do not normally
involve either brokerage commissions or transfer taxes. The cost of executing
portfolio securities transactions of each Fund will primarily consist of
brokerage commissions or underwriter or dealer spreads. Under the Investment
Company Act of 1940, persons affiliated with the Company are prohibited from
dealing with the Company as a principal in the purchase and sale of the
Company's portfolio securities unless an exemptive order allowing such
transactions is obtained from the Securities and Exchange Commission. Since
over-the-counter transactions are usually principal transactions, affiliated
persons of the Company, including Merrill Lynch Government Securities Inc.
("GSI"), Merrill Lynch Money Markets Inc. ("MMI") and Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("Merrill Lynch"), may not serve as the Company's
dealer in connection with such transactions except pursuant to exemptive orders
from the Securities and Exchange Commission, such as the one described below.
However, affiliated persons of the Company may serve as its broker in
over-the-counter transactions conducted on an agency basis, subject to the
Company's policy of obtaining best price and execution. The Company may not
purchase securities from any underwriting syndicate of which Merrill Lynch is a
member except in accordance with rules and regulations under the Investment
Company Act of 1940.

      The Securities and Exchange Commission has issued an exemptive order
permitting the Company to conduct principal transactions with respect to the
Domestic Money Market and Reserve Assets Funds with GSI and MMI in U.S.
Government and government agency securities, and certain other money market
securities, subject to a number of conditions, including conditions designed to
insure that the prices to the Funds available from GSI and MMI are equal to or
better than those available from other sources. GSI and MMI have informed the
Company that they will in no way, at any time, attempt to influence or control
the activities of the Company or the Investment Adviser in placing such
principal transactions. The exemptive order allows GSI and MMI to receive a
dealer spread on any transaction with the Company no greater than their
customary dealer spreads for transactions of the


                                       19
<PAGE>   248

type involved. Certain court decisions have raised questions as to whether
investment companies should seek to "recapture" brokerage commissions and
underwriting and dealer spreads by effecting their purchases and sales through
affiliated entities. In order to effect such an arrangement, the Company would
be required to seek an exemption from the Investment Company Act so that it
could engage in principal transactions with affiliates. The Board of Directors
has considered the possibilities of seeking to recapture spreads for the benefit
of the Company and, after reviewing all factors deemed relevant, has made a
determination not to seek such recapture at this time. The Board will reconsider
this matter from time to time. The Company will take such steps as may be
necessary to effect recapture, including the filing of applications for
exemption under the Investment Company Act of 1940, if the Directors should
determine that recapture is in the best interests of the Company or otherwise
required by developments in the law.

      While the Investment Adviser seeks to obtain the most favorable net
results in effecting transactions in the Funds' portfolio securities, dealers
who provide supplemental investment research of the Investment Adviser may
receive orders for transactions by the Funds. Such supplemental research
services ordinarily consist of assessments and analysis of the business or
prospects of a company, industry or economic sector. If, in the judgment of the
Investment Adviser, a particular Fund or Funds will be benefited by such
supplemental research services, the Investment Adviser is authorized to pay
spreads or commissions to brokers or dealers furnishing such services which are
in excess of spreads or commissions which another broker or dealer may charge
for the same transaction. Information so received will be in addition to and not
in lieu of the services required to be performed by the Investment Adviser under
the Investment Advisory Agreements. The expenses of the Investment Adviser will
not necessarily be reduced as a result of the receipt of such supplemental
information. In some cases, the Investment Adviser may use such supplemental
research in providing investment advice to its other investment advisory
accounts. For the fiscal year ended December 31, 1997, the Company paid
brokerage commissions of $18,344,021, of which $302,843 was paid to Merrill
Lynch. For the fiscal year ended December 31, 1996, the Company paid brokerage
commissions of $6,656,814 of which $266,405 was paid to Merrill Lynch.

Portfolio Turnover

      Each Fund has a different expected rate of portfolio turnover; however,
rate of portfolio turnover will not be a limiting factor when management of the
Company deems it appropriate to purchase or sell securities for a Fund. Because
of the short-term nature of the securities in which the Domestic Money Market
and Reserve Assets Funds will invest, and because such Funds' investments will
be constantly changing in response to market conditions, no portfolio turnover
rate may be accurately stated for the Domestic Money Market and Reserve Assets
Funds.

      Below are  portfolio  turnover  rates for each of the Funds for the fiscal
years ended December 31, 1997 and December 31, 1996:

*   In connection with a reorganization on December 6, 1996 conducted by the
    Company with respect to certain of its Funds, the Company, with the approval
    of the affected shareholders of the Funds, caused (i) Global Bond Focus
    Fund(a) to acquire substantially all of the assets and assume substantially
    all the liabilities of the International Bond Fund, a separate Fund of the
    Company, (b) to implement a change in its investment objective and policies
    from seeking high current income from a global portfolio of fixed income
    securities, including non-investment grade securities, to seeking a high
    total investment return by investing in a global portfolio of investment
    grade fixed income securities and (c) to change its name from the World
    Income Focus Fund to its current name; (ii) the Government Bond Fund (x) to
    implement a change in its investment objective so that the Fund may invest
    in any debt securities issued or guaranteed by the U.S. Government, its
    agencies or instrumentalities without regard to remaining maturity and (y)
    to change its name from the Intermediate Government Bond Fund to its current
    name; and(iii) the Global Strategy Focus Fund to acquire substantially all
    of the assets and assume substantially all the liabilities of the Flexible
    Strategy Fund, a separate Fund of the Company. As a result, the portfolio
    turnover rates for the fiscal years set forth in the table for the Global
    Bond Focus Fund, the Global Strategy Focus Fund and the Government Bond Fund
    may not be indicative of future portfolio turnover rates of such Funds. **
    For the period from December 13, 1996 (commencement of operations) to
    December 31, 1996.

                              REDEMPTION OF SHARES

      The right to redeem shares or to receive payment with respect to any
redemption may only be suspended for any period during which trading on the New
York Stock Exchange is restricted as determined by the Securities and Exchange
Commission or such Exchange is closed (other than customary weekend and holiday
closings), for any period during which an emergency exists as defined by the
Securities and Exchange Commission as a result of which disposal of portfolio
securities or determination of the net asset value of each Fund is not
reasonably practicable, and for such other periods as the Securities and
Exchange Commission may by order permit for the protection of shareholders of
each Fund.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES

Dividends and Distributions

      Reference is made to "Dividends, Distributions and Taxes" in the Appendix
to the Prospectus.

Federal Income Taxes

      Under the Internal Revenue Code of 1986, as amended (the "Code"), each
Fund of the Company will be treated as a separate corporation for federal income
tax purposes and, thus, each Fund is required to satisfy the qualification
requirements under the Code for treatment as a regulated investment company.
There will be no offsetting of capital gains and losses among the Funds. Each
Fund intends to continue to qualify as a regulated investment company under
certain provisions of the Code. Under such provisions, a Fund will not be
subject to federal income tax on such part of its net ordinary income and net
realized capital gains which it distributes to shareholders. To qualify for
treatment as a regulated investment company, a Fund must, among other things,
derive in each taxable year at least 90% of its gross income from dividends,
interest, payments with respect to securities loans, and gains from the sale or
other disposition of securities and derive less than 30% of its gross income in
each taxable year from the gains (without deduction for losses) from the sale or
other disposition of stocks, securities, certain options, futures or forward
contracts and certain foreign currencies held for less than three


                                       21
<PAGE>   250

months. In addition, the Code requires that each Fund meet certain
diversification requirements, including the requirement that not more than 25%
of the value of a Fund's total assets be invested in the securities (other than
U.S. Government securities or the securities of other regulated investment
companies) of any one issuer. Each of the Company's Funds, including the Natural
Resources Focus Fund, intends to comply with the above-described requirements.

      On occasion, some amount of the distributions of the Domestic Money Market
Fund or the Reserve Assets Fund for a fiscal year may constitute a return of
capital, in which case such amount would be applied against and reduce the
Separate Account's tax basis in shares of such Fund. If such amount were to
exceed the Separate Account's tax basis for shares of the Domestic Money Market
Fund or the Reserve Assets Fund, the excess would be treated as gain from the
sale or exchange of such shares.

      On occasion the net income of the Domestic Money Market Fund or the
Reserve Assets Fund may be a negative amount as a result of a net decline in the
value of the portfolio securities of the Fund which is in excess of the interest
earned. Consequently, the Fund will reduce the number of its outstanding shares
to reflect the negative net income. The adjustment may result in gross income to
shareholders in excess of the net dividend credited to such shareholders for a
period. In such a case, such shareholders' tax basis in the shares of the
Domestic Money Market Fund or the Reserve Assets Fund may be adjusted to reflect
the difference between taxable income and net dividends actually distributed.
Such difference may be realized as a capital loss when the shares are
liquidated.

      The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations presently in effect. 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 or administrative action, and such change
may apply retroactively.

                            DISTRIBUTION ARRANGEMENTS

      The Company has entered into a distribution agreement (the "Distribution
Agreement") with Merrill Lynch Funds Distributor, Inc. with respect to the sale
of the Company's shares, other than shares of the Class A Common Stock and Class
B Common Stock of the Global Growth Fund and the Capital Focus Fund, to the
Distributor for resale to Insurance Companies' accounts. Such shares will be
sold at their respective net asset values and therefore will involve no sales
charge. The Distributor is a wholly owned subsidiary of the Investment Adviser.
The continuation of the Distribution Agreement was approved by the Company's
Board of Directors at a meeting held on March 26, 1997 and will continue in
effect until June 30, 1998.

      The Distribution Agreement is subject to the same renewal requirements and
termination provisions as the Investment Advisory Agreements described above.

                                PERFORMANCE DATA

      From time to time the average annual total return and other total return
data, as well as yield, of one or more of the Company's Funds may be included in
advertisements or information furnished to present or prospective Contract
Owners. Total return and yield figures are based on the Fund's historical
performance and are not intended to indicate future performance. Average annual
total return and yield are determined in accordance with formulas specified by
the Securities and Exchange Commission. In connection with its reorganization on
December 6, 1996, the Global Bond Focus Fund (i) acquired substantially all of
the assets and assumed substantially all the liabilities of the International
Bond Fund, a separate Fund of the Company, (ii) implemented a change in its
investment objective and policies from seeking high current income from a global
portfolio of fixed income securities, including non-investment grade securities,
to seeking a high total investment return by investing in a global portfolio of
investment grade fixed income securities and (iii) changed its name from the
World Income Focus Fund to its current name. For the period from the
commencement of the World Income Focus Fund's operations


                                       22
<PAGE>   251

through its reorganization on December 6, 1996, the portfolio of the Fund
included debt securities rated below investment grade (i.e., junk bonds). On
December 6, 1996, the Government Bond Fund (i) implemented a change in its
investment objective so that the Fund may invest in any debt securities issued
or guaranteed by the U.S. Government, its agencies or instrumentalities without
regard to remaining maturity and (ii) changed its name from the Intermediate
Government Bond Fund to its current name. For the period from the commencement
of the Fund's operations through December 6, 1996, the portfolio of the
Intermediate Government Bond Fund consisted primarily of intermediate-term debt
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities with a maximum maturity not to exceed fifteen years. As a
result of the foregoing changes in the investment objective of each of the
Global Bond Focus Fund and the Government Bond Fund, the performance information
set forth herein and in the Prospectus for the period prior to December 6, 1996
may not be indicative of future performance of each Fund.

      Average annual total return quotations for the specified periods are
computed by finding the average annual compounded rates of return (based on net
investment income and any realized and unrealized capital gains or losses on
portfolio investments over such periods) that would equate the initial amount
invested to the redeemable value of such investment at the end of each period.
Average annual total return is computed assuming all dividends and distributions
are reinvested and taking into account all applicable recurring and nonrecurring
expenses.

      The Reserve Assets Fund and the Domestic Money Market Fund normally
compute annualized yield by determining the net change for a seven-day base
period, exclusive of capital changes, in the value of a hypothetical
pre-existing account having a balance of one share at the beginning of the
period, dividing the net change in account value by the value of the account at
the beginning of the base period to obtain the base period return, and
multiplying the base period return by 365 and then dividing by seven. Under this
calculation, the yield does not reflect realized and unrealized gains and losses
on portfolio securities. The Funds may also include its yield in advertisements,
calculated in the same manner as set forth above but including realized and
unrealized gains and losses. The Securities and Exchange Commission also permits
the calculation of a standardized effective or compounded yield. This is
computed by compounding the unannualized base period return by dividing the base
period by seven, adding one to the quotient, raising the sum to the 365th power,
and subtracting one from the result. This compounded yield calculation also
excludes realized or unrealized gains or losses on portfolio securities.

      Set forth below is average annual total return information for the shares
of each of the Company's Funds, other than the Reserve Assets Fund and Domestic
Money Market Fund. The total return quotations may be of limited use for
comparative purposes because they do not reflect charges imposed at the Separate
Account level which, if included, would decrease total return.

Item 27. Indemnification.

      Under Section 2-418 of the Maryland General Corporation Law, with respect
to any proceedings against a present or former director, officer, agent or
employee (a "corporate representative") of the Registrant, except a proceeding
brought by or on behalf of the Registrant, the Registrant may indemnify the
corporate representative against expenses, including attorneys' fees and
judgments, fines and amounts paid in settlement actually and reasonably incurred
by the corporate representative in connection with the proceeding, if: (i) he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Registrant; and (ii) with respect to any
criminal proceeding, he had no reasonable cause to believe his conduct was
unlawful. The Registrant is also authorized under Section 2-418 of the Maryland
General Corporation Law to indemnify a corporate representative under certain
circumstances against expenses incurred in connection with the defense of a suit
or action by or in the right of the Registrant. Under each Distribution
Agreement, the Registrant has agreed to indemnify the Distributor against any
loss, liability, claim, damage or expense arising out of any untrue statement of
a material fact, or an omission to state a material fact, in any registration
statement, prospectus or report to shareholders of the Registrant. Reference is
made to Article VI of Registrant's Certificate of Incorporation, Article VI of
Registrant's By-Laws, Section 2-418 of the Maryland General Corporation Law and
Section 9 of each Distribution Agreement.

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