                           ASSET ALLOCATION PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Asset Allocation Portfolio is a mutual fund with an investment objective to
seek high total investment return consistent with prudent investment risk
through a fully managed investment policy utilizing equity securities as well as
investment grade intermediate- and long-term debt securities and money market
securities. Total investment return consists of current income (including
dividends, interest and discount accruals) and capital appreciation or
depreciation. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing in a portfolio of equity securities,
investment grade intermediate- and long-term debt securities, including
preferred stocks, convertible preferred stocks and convertible debt securities,
and money market securities. The composition of the Portfolio will vary from
time to time to reflect the investment adviser's views on economic and market
trends and the anticipated relative total investment return available from a
particular type of security. The Portfolio may invest up to 25% of its total
assets in securities of foreign issuers. The Portfolio may invest in certain
derivatives, such as options and futures, which may subject the Portfolio to
additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. The prices of
the Portfolio's equity securities may or may not fluctuate in tandem with
overall changes in the stock markets. The prices of debt securities tend to fall
as interest rates rise, and such declines may be greater among securities with
longer maturities. The prices of convertible securities are affected by changes
similar to those of debt and equity securities. The value of a convertible
security tends to decline as interest rates rise and, because of the conversion
feature, tends to vary with fluctuations in the market value of the underlying
common stock.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Because the Portfolio generally invests in investment
grade-quality debt securities, it is subject to a lower level of credit risk
than a portfolio investing more in lower-grade quality securities.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek high total investment return over the long term.

- - Can withstand volatility in the value of their shares in the Portfolio.

- - Wish to add to their personal investment holdings a portfolio that invests in
  a varying mix of equity, debt securities and money market securities seeking
  high total investment return.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio's Class I Shares over the past ten calendar years prior
to the date of this prospectus. Sales charges or other expenses at the contract
level are not reflected in this chart. If sales charges or other expenses at the
contract level had been included, the returns shown below would have been lower.
Remember that the past performance of the Portfolio is not indicative of its
future performance.

                               COMSTOCK PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Comstock Portfolio is a mutual fund with an investment objective to seek
capital growth and income through investments in equity securities, including
common stocks, preferred stocks and securities convertible into common and
preferred stocks. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing in a portfolio of equity securities,
consisting principally of common stocks. The Portfolio emphasizes a "value"
style of investing seeking well-established, undervalued companies believed to
possess the potential for capital growth and income. The Portfolio may invest up
to 15% of its total assets in securities of foreign issuers. The Portfolio may
invest in certain derivatives, such as options and futures, which may subject
the Portfolio to additional risks.

                                INVESTMENT RISKS

Investors who seek only long-term capital growth should be aware that the
Portfolio also seeks to generate income and that capital growth is only a part
of the Portfolio's overall investment objective. Similarly, investors who seek a
more assured level of current income should be aware that the Portfolio's income
will fluctuate and that seeking income is only a part of the Portfolio's overall
investment objective.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. A "value"
style of investing emphasizes undervalued companies with characteristics for
improved valuations. This style of investing is subject to the risks that the
valuations never improve or that the returns on "value" equity securities are
less than the returns on other styles of investing or the overall stock markets.
During an overall stock market decline, stock prices of small- or medium-sized
companies (in which the Portfolio may invest) often fluctuate more than prices
of larger companies. The ability of the Portfolio's investment holdings to
generate income depends on the earnings and the continuing declaration of
dividends by the issuers of such securities.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in

instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek capital growth and income over the long term.

- - Wish to add to their personal investment holdings a portfolio that emphasize a

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors

trading vehicle.


The Comstock Portfolio commenced investment operations as of April 30, 1999.
Accordingly, the Portfolio does not have a full calendar year of historical
annual performance or comparative performance to provide to investors.

                              RISK/RETURN SUMMARY

                             INVESTMENT OBJECTIVES

The Domestic Income Portfolio is a mutual fund with a primary investment
objective to seek current income. When consistent with the primary investment
objective, capital appreciation is a secondary investment objective. There can
be no assurance that the Portfolio will achieve its investment objectives.

                             INVESTMENT STRATEGIES

The Portfolio's management seeks to achieve the investment objectives by
investing primarily in a diversified portfolio of income securities, including
convertible and non-convertible debt securities and preferred stocks. Under
normal market conditions, the Portfolio invests at least 80% of its total assets
in income securities rated at the time of purchase B or higher by Standard &
Poor's ("S&P") or rated B or higher by Moody's Investors Service, Inc.
("Moody's") or unrated securities judged by the Portfolio's investment adviser
to be of comparable quality at the time of purchase. Securities rated BB or
below by S&P or rated Ba or below by Moody's or unrated securities of comparable
quality are commonly referred to as "junk bonds" and involve special risks as
compared to investments in higher-grade securities (see sidebar for an
explanation of quality ratings). The Portfolio may invest up to 25% of its total
assets in securities of foreign issuers. The Portfolio may purchase or sell

                              QUALITY RATINGS

Security ratings are based on the issuer's ability to pay interest and repay
the principal. Securities with ratings above the line are considered
"investment grade," while those with ratings below the line are regarded as
"noninvestment grade," or "junk bonds." A detailed explanation of these
ratings can be found in the appendix to this prospectus.

                                INVESTMENT RISKS

With its holdings of medium- and lower-grade securities, the Portfolio has
greater risks than a portfolio owning only higher-grade securities.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. The prices of income securities tend to
fall as interest rates rise and such declines tend to be greater among
securities with longer durations. Although the Portfolio has no policy limiting
the maturities of its investments, the Portfolio's investment adviser seeks to
maintain the dollar-weighted average duration of the Portfolio between four to
six years. This means the Portfolio generally will be subject to greater market
risk than a portfolio that owns only shorter term securities but lesser market
risk than a portfolio that owns only longer term securities. Lower-grade
securities, especially those with longer durations or that do not make regular
interest payments, may fluctuate more in price in response to negative issuer or
general economic news than higher-grade securities. When-issued and

                                        7
<PAGE>   10

delayed delivery transactions are subject to changes in market conditions from
the time of the commitment until settlement. This may adversely affect the
prices or yields of the securities being purchased, as well as any portfolio
securities held for payment of such commitments. The greater the Portfolio's
outstanding commitments for these securities, the greater the Portfolio's
exposure to market price fluctuation.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Because the Portfolio may invest in securities with
below investment grade credit quality, the Portfolio is subject to a higher
level of credit risk than a portfolio that buys only investment grade
securities. The credit quality of "noninvestment grade" securities is considered
speculative by recognized rating agencies with respect to the issuer's
continuing ability to pay interest and principal. Lower-grade securities may
have less liquidity and a higher incidence of default than investments in
higher-grade securities. The Portfolio may incur higher expenditures to protect
the Portfolio's interest in such securities. The credit risks and market prices
of lower-grade securities are more sensitive to negative issuer developments,
such as reduced revenues or increased expenditures, or adverse economic
conditions, such as a recession, than higher-grade securities.

INCOME RISK. The income you receive from the Portfolio is based primarily on
interest rates, which can vary widely over the short and long term. If interest
rates drop, your income from the Portfolio may drop as well.

CALL RISK. If interest rates fall, it is possible that issuers of securities
with high interest rates will prepay or "call" their securities before their
maturity dates. In this event, the proceeds from the called securities would be
reinvested by the Portfolio in securities with the new, lower interest rates,
resulting in a possible decline in the Portfolio's income and distributions to
shareholders.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objectives and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek current income and capital appreciation over the long term.

- - Are willing to take on the increased risks of medium- and lower-grade
  securities in exchange for potentially higher income.

- - Wish to add to their personal investment holdings a portfolio that invests
  primarily in income securities, including medium- and lower-grade income
  securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio's Class I Shares over the past ten calendar years prior
to the date of this prospectus. Sales charges or other expenses at the contract
level are not reflected in this chart. If sales charges or other expenses at the
contract level had been included, the returns shown below would have been lower.
Remember that the past performance of the Portfolio is not indicative of its
future performance.

                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE


The Emerging Growth Portfolio is a mutual fund with an investment objective to
seek capital appreciation. There can be no assurance that the Portfolio will
achieve its investment objective.


                             INVESTMENT STRATEGIES


Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the Portfolio's investment objective by investing at least 65% of the
Portfolio's total assets in common stocks of emerging growth companies. Emerging
growth companies are those companies in the early stages of their life cycles
that the Portfolio's investment adviser believes have the potential to become
major enterprises. Investing in such companies involves risks not ordinarily
associated with investments in larger, more established companies. The Portfolio
may invest up to 20% of its total assets in securities of foreign issuers. The
Portfolio may invest in certain derivatives, such as options and futures, which
may subject the Portfolio to additional risks.


                                INVESTMENT RISKS


An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.



MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. During an
overall market decline, stock prices of small- and medium-sized companies (in
which the Portfolio may invest) often fluctuate more and often fall more than
the prices of larger sized company stocks. It is possible that the stocks of
small- and medium-sized companies will be more volatile and underperform the
overall stock market. Historically, smaller- and medium-sized company stocks
have sometimes gone through extended periods when they did not perform as well
as larger company stocks.


RISKS OF EMERGING GROWTH COMPANIES. Companies that the Portfolio's management
believe are emerging growth companies are often companies with limited product
lines, markets, distribution channels or financial resources and the management
of such companies may be dependent upon one or a few key people. The stocks of
emerging growth companies can therefore be subject to more abrupt or erratic
market movements than stocks of larger, more established companies or the stock
market in general.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek capital appreciation over the long term.


- - Are willing to take on the increased risks of investing in emerging growth
  companies in exchange for potentially higher capital appreciation.


- - Can withstand substantial volatility in the value of their shares of the
  Portfolio.


- - Wish to add to their personal holdings a portfolio that invests primarily in
  common stocks of emerging growth companies.



An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is

                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Enterprise Portfolio is a mutual fund with an investment objective to seek
capital appreciation through investments in securities believed by the
Portfolio's investment adviser to have above average potential for capital
appreciation. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing primarily in common stocks of "growth"
companies focusing on those securities believed to offer a combination of strong
business fundamentals at an attractive valuation. The Portfolio may invest up to
10% of its total assets in securities of foreign issuers. The Portfolio may
invest in certain derivatives, such as options and futures, which may subject
the Portfolio to additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in common
stocks generally are affected by changes in the stock markets, which fluctuate
substantially over time, sometimes suddenly and sharply. The Portfolio
emphasizes a "growth" style of investing. The market values of "growth" common
stocks may be more volatile than other types of investments. The returns on
"growth" securities may or may not move in tandem with the returns on other
styles of investing or the overall stock markets. During an overall stock market
decline, stock prices of small- or medium-sized companies (in which the
Portfolio may invest) often fluctuate more than prices of larger companies.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek capital appreciation over the long term.

- - Do not seek current income from their investment.

- - Can withstand substantial volatility in the value of their shares of the
  Portfolio.

- - Wish to add to their personal investment holdings a portfolio that emphasizes
  a "growth" style of investing in common stocks.

An investment in the Portfolio may not be appropriate for all investors. The

                                   PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Global Equity Portfolio is a mutual fund with an investment objective to
seek long-term growth of capital through investments in an internationally
diversified portfolio of equity securities of companies of any nation including
the United States. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

The Portfolio's management seeks to achieve the investment objective by
investing in an internationally diversified portfolio of equity securities,
including common stocks, preferred stocks and warrants or options to acquire
such securities. The Fund's management uses a "top-down" investment management
approach that emphasizes country selection and weighting rather than individual
security selection. Within a particular country, the Portfolio selects
securities of issuers that would replicate a broad market index for that
country. The Portfolio may invest in any country, including developed or
undeveloped countries. Under normal market conditions, the Portfolio invests at
least 65% of its total assets in securities of issuers of at least three
countries (including the United States). Investments in securities of foreign
issuers include certain risks not typically associated with investments in U.S.
securities. The Portfolio may invest in certain derivatives, such as options and
futures, which may subject the Portfolio to additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. Foreign
markets may, but often do not, move in tandem with changes in U.S. markets, and
foreign markets may have more price volatility than U.S. markets. During an
overall stock market decline, stock prices of small- and medium-sized companies
(in which the Portfolio may invest) often fluctuate more than prices of larger
companies.

FOREIGN RISKS. Because the Portfolio will own securities from foreign issuers,
it will be subject to risks not usually associated with owning securities of
U.S. issuers. These risks can include fluctuations in foreign currencies,
foreign currency exchange controls, political and economic instability,
differences in financial reporting, differences in securities regulation and
trading, and foreign taxation issues. The risks of investing in developing or
emerging markets (in which the Portfolio may invest) are greater than the risks
generally associated with foreign investments including greater political
uncertainties, an economy's dependence on international development assistance,
currency transfer restrictions, and greater delays and disruptions in settlement
transactions.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Fund may be appropriate
for investors who:

- - Seek long-term growth of capital.

- - Are willing to take on the increased risks associated with investing in
  foreign securities.

- - Can withstand volatility in the value of their shares in the Portfolio.

- - Wish to add to their personal investment holdings a portfolio that invests in
  an international portfolio of equity securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio's Class I Shares over the past four calendar years
prior to the date of this prospectus. Sales charges or other expenses at the
contract level are not reflected in this chart. If sales charges or other
expenses at the contract level had been included, the returns shown below would
have been lower. Remember that the past performance of the Portfolio is not
indicative of its future performance.

                              GOVERNMENT PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Government Portfolio is a mutual fund with an investment objective to seek
to provide investors with high current return consistent with preservation of
capital. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing at least 80% of the Portfolio's total assets
in debt securities issued or guaranteed by the U.S. government, its agencies or
its instrumentalities, including mortgage-related securities issued or
guaranteed by agencies or instrumentalities of the U.S. government. Under normal
market conditions, the Portfolio may invest up to 20% of its total assets in
government-related securities, including privately issued mortgage-related and
mortgage-backed securities not directly issued or guaranteed by
instrumentalities of the U.S. government, privately issued certificates
representing "stripped" U.S. government or mortgage-related securities and
repurchase agreements fully collateralized by U.S. government securities. The
Portfolio may invest in certain derivatives, such as options, futures and
options on futures, and interest rate swaps or other interest rate-related
transactions, which may subject the Portfolio to additional risks. The Portfolio
may purchase or sell securities on a when-issued or delayed delivery basis.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. The value of debt securities tend to fall
as interest rates rise and such declines tend to be greater among debt
securities with longer maturities or longer durations. Although the Portfolio
has no policy limiting the maturities of its investments, the Portfolio's
management seeks to moderate market risk by normally maintaining a portfolio
duration of four to six years. This means that the Portfolio will be subject to
greater market risk than a portfolio investing solely in shorter-term securities
but lesser market risk than a portfolio investing solely in longer-term
securities (see sidebar for an explanation of maturities and durations). The
yields and market prices of U.S. government securities may move differently and
adversely compared to the yields and market prices of the overall securities
markets. These securities, while backed by the U.S. government, are not
guaranteed against declines in their market prices.

The prices of mortgage-related securities, like traditional debt securities,
tend to fall as interest rates rise. Mortgage-related securities may be more
susceptible to further price declines than traditional debt securities in
periods of rising interest rates because of extension risk (described below).
Additionally, mortgage-related securities may benefit less than traditional debt
securities during periods of declining interest rates because of prepayment risk
(described below).

Market risk is often greater among certain types of debt securities, such as
zero-coupon securities or mortgage-related stripped securities, which do not
make regular or periodic interest payments. As interest rates change, these
securities often fluctuate more in price than securities that make current
interest payments. Therefore, the Portfolio may be subject to greater market
risk than a portfolio that does not own these types of securities.

Investments in when-issued and delayed delivery transactions are subject to
changes in market conditions from the time of the commitment until settlement.
This may adversely affect the prices or yields of the securities being
purchased, as well as any portfolio securities held for payment of such
commitments. The greater the Portfolio's outstanding commitments for these
securities, the greater the Portfolio's exposure to market price fluctuation.

                                     MATURITIES

    A debt security can be categorized according to its maturity, which is the
    length of time before the issuer must repay the principal.

                                    DURATION

    Duration provides an alternative approach to assessing a security's market
    risk. Duration measures the expected life of a security by incorporating the
    security's yield, coupon interest payments, final maturity and call features
    into one measure. While maturity focuses only on the final principal
    repayment date of a security, duration looks at the timing and present value
    of all of a security's principal, interest or other payments. Typically, a
    debt security with interest payments due prior to maturity has a duration
    less than maturity. A zero-coupon bond, which does not make interest
    payments prior to maturity, would have the same duration and maturity.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Credit risk should be low for the Portfolio because
it invests substantially all of its assets in U.S. government securities.

INCOME RISK. The income you receive from the Portfolio is based primarily on
interest rates, which can vary widely over the short and long term. If interest
rates drop, your income from the Portfolio may drop as well. The more the
Portfolio invests in adjustable, variable or floating rate securities or in
securities susceptible to prepayment risk, the greater the Portfolio's income
risk.

PREPAYMENT RISK. If interest rates fall, the principal on debt securities held
by the Portfolio may be paid earlier than expected. If this happens, the
proceeds from a prepaid security would be reinvested by the Portfolio in
securities bearing the new, lower interest rates, resulting in a possible
decline in the Portfolio's income and distributions to shareholders.

The Portfolio may invest in mortgage-related securities, which are especially
sensitive to prepayment risk because property owners often refinance their
mortgages when interest rates drop.

EXTENSION RISK. The value of debt securities tends to fall as interest rates
rise. For mortgage-related securities, if interest rates rise, property owners
may prepay mortgages more slowly than expected when the security was purchased
by the Portfolio which may further reduce the market value of such security and
lengthen the duration of the security.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options, futures and options on futures, interest
rate swaps and other interest-rate related transactions are examples of
derivatives. Such transactions involve risks different from the direct
investment in underlying securities such as imperfect correlation between the
value of the instruments and the underlying assets; risks of default by the
other party to certain transactions; risks that the transactions may result in
losses that partially or completely offset gains in portfolio positions; risks
that the transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

appropriate for investors who:

- - Seek high current return consistent with preservation of capital.

- - Wish to add to their personal investment holdings a portfolio that invests
  primarily in debt securities issued or guaranteed by the U.S. government, its

Portfolio will achieve its investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing primarily in income-producing equity
securities, including common stocks and convertible securities; although
investments are also made in non-convertible preferred stocks and debt
securities. In selecting securities for investments the Portfolio focuses
primarily on the security's potential for growth of capital and income. The
Portfolio's management may focus on larger capitalization companies which it
believes possess characteristics for improved valuation. The Portfolio may
invest up to 15% of its total assets in securities of foreign issuers. The
Portfolio may invest in certain derivatives, such as options and futures, which
may subject the Portfolio to additional risks.

                                INVESTMENT RISKS

Investors who seek a more assured level of current income should be aware that
the Portfolio's income will fluctuate and that seeking income is only a part of
the Portfolio's overall investment objective. Similarly, investors who seek only
long-term growth should be aware that the Portfolio seeks to generate income and
that long-term growth of capital is only a part of the Portfolio's overall
investment objective.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. During an
overall stock market decline, stock prices of small- or medium-sized companies
or newly-formed companies (in which the Portfolio may invest) often fluctuate
more than prices of larger, more established companies. The ability of the
Portfolio's equity securities holdings to generate income is dependent on the
earnings and the continuing declaration of dividends by the issuers of such
securities. The values of income-producing equity securities may or may not
fluctuate in tandem with overall changes in the stock markets. The Portfolio's
investments in fixed income or debt securities generally are affected by changes
in interest rates and creditworthiness of the issuer. The market prices of such
securities tend to fall as interest rates rise, and such declines may be greater
among securities with longer duration. The Portfolio's investments in
convertible securities are affected by changes similar to those of equity and
debt securities. The value of convertible securities tends to decline as
interest rates rise and, because of the conversion feature, tends to vary with
fluctuations in the market value of the underlying equity security.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; and risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek growth of capital and income over the long term.

- - Can withstand volatility in the value of their shares of the Portfolio.

- - Wish to add to their personal investment holding a portfolio that invests
  primarily in income-producing equity securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio's Class I Shares over the past three calendar years
prior to the date of this prospectus. Sales charges or other expenses at the
contract level are not reflected in this chart. If sales charges or other
expenses at the contract level had been included, the returns shown below would
have been lower. Remember that the past performance of the Portfolio is not
indicative of its future performance.

                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Money Market Portfolio is a mutual fund with an investment objective to seek
protection of capital and high current income through investments in money
market instruments. There can be no assurance that the Portfolio will achieve
its investment objective.

                             INVESTMENT STRATEGIES

The Portfolio seeks to maintain a constant net asset value of $1.00 per share by
investing in a diversified portfolio of money market instruments maturing within
one year with a dollar-weighted average maturity of 90 days or less. The
Portfolio seeks high current income from these short-term investments to the
extent consistent with protection of capital.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks.

INCOME RISK. The income you receive from the Portfolio is based primarily on
short-term interest rates, which can vary widely over time. If short-term
interest rates drop, your income from the Portfolio may drop as well.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Credit risk should be low for the Portfolio because
it invests in high-quality money market instruments.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. An investment in the Portfolio is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency. Although the Portfolio seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in the
Portfolio.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek protection of capital and high current income through investments in
  money market instruments.

                               ANNUAL PERFORMANCE

                              RISK/RETURN SUMMARY

                             INVESTMENT OBJECTIVES

The Morgan Stanley Real Estate Securities Portfolio is a mutual fund with a
primary investment objective to seek long-term growth of capital. Current income
is a secondary investment objective. There can be no assurance that the
Portfolio will achieve its investment objectives.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objectives by investing at least 65% of the Portfolio's total assets
in a portfolio of securities of companies operating in the real estate industry,
including equity securities of real estate investment trusts ("REITs") and other
securities of real estate operating companies. The Portfolio's management
diversifies its investments as to issuers, property types and regions. The
Portfolio's management emphasizes a bottom-up stock selection with a top-down
asset allocation overlay. A company operating in the real estate industry is one
that derives at least 50% of its assets, gross income or net profits from the
ownership, construction, management or sale of residential, commercial or
industrial real estate. Besides equity securities of REITs, the Portfolio may
invest in equity securities, including common stocks and convertible securities,
or non-convertible preferred stocks and investment-grade quality securities of
companies operating in the real estate industry. The Portfolio may invest up to
35% of its total assets in securities of companies outside the real estate
industry. The Portfolio may invest up to 25% of its total assets in securities
of foreign issuers, some or all of which may be in the real estate industry. The
Portfolio may invest in certain derivatives, such as options and futures, which
may subject the Portfolio to additional risks.

                                INVESTMENT RISKS

Because of the Portfolio's policy of concentrating its investments in securities
of companies operating in the real estate industry, the Portfolio is subject to
certain risks associated with the ownership of real estate and with the real
estate industry in general.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. The prices of
equity securities of companies in the real estate industry may be more volatile
and may not fluctuate in tandem with overall changes in the stock markets. The
value of debt securities tend to fall as interest rates rise, and such declines
may be greater among securities with longer maturities.

RISKS OF INVESTING IN REAL ESTATE. Because of the Portfolio's policy of
concentrating its of investments in securities of companies operating in the
real estate industry and because a substantial portion of the Portfolio's
investments may be comprised of REITs, the Portfolio is more susceptible to
risks associated with the ownership of real estate and with the real estate
industry in general. These risks can include fluctuations in the value of
underlying properties; defaults by borrowers or tenants; market saturation;
changes in general and local economic conditions; decreases in market rates for
rents; increases in competition, property taxes, capital expenditures, or
operating expenses; and other economic, political or regulatory occurrences
affecting the real estate industry. In addition, REITs depend upon specialized
management skills, may have limited financial resources, may have less trading
volume and may be subject to more abrupt or erratic price movements than the
overall securities markets. REITs must comply with certain federal income tax
law requirements to maintain their federal income tax status. Some REITs
(especially mortgage REITs) are affected by risks similar to those associated
with investments in debt securities including changes in interest rates and the
quality of credit extended.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options, futures, and forward contracts are
examples of derivatives. Such transactions involve risks different from the
direct investment in underlying securities, such as imperfect correlation
between the value of the instruments and the underlying assets; risks of default
by the other party to certain transactions; risks that the transactions may
result in losses that partially or completely offset gains in portfolio
positions; risks that the transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek to grow their capital over the long term.

- - Are willing to take on the increased risks of an investment concentrated in
  securities of companies that operate within the same industry.

- - Can withstand volatility in the value of their shares of the Portfolio.

- - Wish to add to their personal investment holdings a portfolio that invests
  primarily in companies operating in the real estate industry.

Investors should carefully consider the additional risks associated with the
Portfolio's policy of concentrating its investments in securities of companies
operating in the real estate industry. An investment in the Portfolio may not be
appropriate for all investors. The Portfolio is not intended to be a complete
investment program, and investors should consider their long-term investment
goals and financial needs when making an investment decision about the
Portfolio. An investment in the Portfolio is intended to be a long-term
investment and the Portfolio should not be used as a trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual

prior to the date of this prospectus. Sales charges or other expenses at the
contract level are not reflected in this chart. If sales charges or other
expenses at the contract level had been included, the returns shown below would
have been lower. Remember that the past performance of the Portfolio is not
indicative of its future performance.

                                   PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Strategic Stock Portfolio is a mutual fund with an investment objective to
seek an above average total return through a combination of potential capital
appreciation and dividend income, consistent with the preservation of invested
capital. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing in a portfolio of high dividend yielding
equity securities of companies included in the Dow Jones Industrial Average (the
"DJIA") or in the Morgan Stanley Capital International USA Index (the "MSCI USA
Index"). The Portfolio's investment adviser buys and sells investment securities
based primarily upon specific objective criteria (emphasizing dividend yield)
applied to DJIA and MSCI USA Index companies. The Portfolio may invest in
certain derivatives, such as options and futures, which may subject the
Portfolio to additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. The Portfolio
emphasizes high dividend yielding stocks selected based upon specific objective
criteria. The market value of the Portfolio's equity securities may or may not
fluctuate in tandem with overall changes in the stock markets. The ability of
the Portfolio's investment holdings to generate income is dependent on the
earnings and the continuing declaration of dividends by the issuers of such
securities.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

STYLE RISK. Securities are purchased and sold for the Portfolio based primarily
upon specific objective criteria. The Portfolio's style may not be as successful
in selecting the best-performing securities as other styles and may underperform
the overall market.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek an above average total return through a combination of potential capital
  appreciation and dividend income.

- - Can withstand volatility in the value of their shares in the Portfolio.

- - Wish to add their personal investment holdings a portfolio that invests
  primarily in equity securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
return of the Portfolio's Class I Shares over the past two calendar years prior
to the date of this prospectus. Sales charges or other expenses at the contract
level are not reflected in this chart. If sales charges or other expenses at the
contract level had been included, the returns shown below would have been lower.
Remember that the past performance of the Portfolio is not indicative of its
future performance.

                                VAN KAMPEN LIFE
                                INVESTMENT TRUST
                              GENERAL INFORMATION


Van Kampen Life Investment Trust (the "Trust") is a diversified, open-end
management investment company which offers shares in eleven separate Portfolios
(the "Portfolios"). Each Portfolio is in effect a separate mutual fund. Each
Portfolio has its own income, expenses, assets, liabilities and net asset value
and each Portfolio issues its own shares.



Shares of each Portfolio represent an interest only in that Portfolio. Each
Portfolio offers two classes of shares -- designated as Class I Shares and Class
II Shares. Prior to May 1, 2000, each Portfolio issued one class of shares and
that class of shares has been designated as Class I Shares. The Class I Shares
of each Portfolio are offered by this prospectus (and the Class II Shares of
each Portfolio are offered through a separate prospectus). Shares are sold only
to separate accounts (the "Accounts") of various insurance companies to fund the
benefits of variable annuity or variable life insurance policies (the
"Contracts"). The Accounts may invest in shares of the Portfolios in accordance
with allocation instructions received from contract owners ("Contract Owners").
Such allocation rights, as well as sales charges and other expenses imposed on
Contract Owners by the Contracts, are further described in the accompanying
Contract prospectus.


Each Portfolio of the Trust has a different investment objective(s) which it
pursues through its investment policies as described below under "Investment
Objectives and Policies." The section entitled "Investment Practices" provides
further discussion of certain investment techniques, strategies or risks that
are common to some or all of the Portfolios. The investment objective(s) of each
Portfolio, except the Morgan Stanley Real Estate Securities Portfolio, is a
fundamental policy and may not be changed without shareholder approval of the
holders of a majority of the Portfolio's outstanding voting securities, as
defined in the Investment Company Act of 1940, as amended (the "1940 Act"). With
respect to the Morgan Stanley Real Estate Securities Portfolio, the investment
objectives may be changed by the Board of Trustees without shareholder approval,
but no change is anticipated. If there is a change in the objectives of such
Portfolio, shareholders should consider whether the Portfolio remains an
appropriate investment in light of their then current financial position and
needs. The differences in objectives and policies among the Portfolios can be
expected to affect the return of each Portfolio and the degree and types of
risks to which each Portfolio is subject. There are risks inherent in all
investments in securities; accordingly there can be no assurance that any
Portfolio will achieve its investment objective(s).

                             INVESTMENT OBJECTIVES
                                  AND POLICIES

                           ASSET ALLOCATION PORTFOLIO

The investment objective of the Asset Allocation Portfolio is to seek a high
total investment return consistent with prudent investment risk through a fully
managed investment policy utilizing equity securities as well as investment
grade intermediate-and long-term debt securities and money market securities.
Total investment return consists of current income (including dividends,
interest and discount accrual) and capital appreciation or depreciation. There
are risks inherent in all investments in securities; accordingly, there can be
no assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing in a portfolio of equity
securities, investment grade intermediate- and long-term debt securities,
including preferred stocks, convertible preferred stocks and convertible debt
securities, and money market securities. The Portfolio's investment adviser may
vary the composition of the Portfolio from time to time based upon its
evaluation of economic and market trends and the anticipated relative total
investment return available from a particular type of security. Accordingly, the
Portfolio may, at any given time, be substantially invested in equity
securities, debt securities or money market securities. Achieving the
Portfolio's investment objective depends on the investment adviser's ability to
assess the effect of economic and market trends on different sectors of the
market.

Common stocks are equity securities of a corporation or other entity that
entitle the holder to a pro rata share of the profits of a corporation, if any,
without preference over any other class of securities, including such entity's
debt securities, preferred stock or other

                                       30
<PAGE>   33

senior equity security. Common stock usually carries with it the right to vote
and frequently an exclusive right to do so. The common stocks in which the
Portfolio invests will be primarily those of large capitalization companies with
characteristics including a strong balance sheet, good financial resources, a
satisfactory rate of return on capital, a good industry position and superior
management skills. The Portfolio's investment adviser believes that companies
that conform most closely to these characteristics often tend to exhibit
generally consistent earnings growth. Among the types of securities in which the
Portfolio may invest, the investments in common stocks generally exhibit the
greatest market risk, which at times can substantially impact the market value
of the Portfolio, sometimes suddenly and sharply.

The Portfolio may invest in intermediate- and long-term debt securities
(including preferred stock, convertible preferred stock and convertible debt
securities) which are rated at the time of purchase BBB or better by Standard &
Poor's ("S&P") or rated Baa or better by Moody's Investors Service, Inc.
("Moody's") or unrated securities determined by the Portfolio's investment
adviser to be of comparable quality at the time of purchase. To the extent
investments are made in fixed-income securities, the Portfolio will invest
primarily in such securities which are rated A or better by either rating
agency. A more complete description of security ratings is contained in the
appendix to this prospectus. The market prices of debt securities generally vary
inversely with changes in prevailing interest rates and generally vary more for
debt securities with longer maturities. The Portfolio is not limited as to the
maturities of the debt securities it may purchase and the debt securities in
which the Portfolio intends to invest are those with intermediate- or
longer-maturities. Debt securities with longer maturities generally tend to
produce higher yields but are subject to greater price fluctuation as a result
of changes in interest rates than debt securities with shorter maturities.

Preferred stock generally has a preference as to dividends and liquidation over
an issuer's common stock but ranks junior to debt securities in an issuer's
capital structure. Unlike interest payments on debt securities, preferred stock
dividends are payable only if declared by the issuer's board of directors.
Preferred stock also may be subject to optional or mandatory redemption
provisions.

A convertible security is a bond, debenture, note, preferred stock, warrant or
other security that may be converted into or exchanged for a prescribed amount
of common stock or other equity security of the same or a different issuer
within a particular period of time at a specified price or formula. A
convertible security generally entitles the holder to receive interest paid or
accrued on debt securities or the dividend paid on preferred stock until the
convertible security matures or is redeemed, converted or exchanged. Before
conversion, convertible securities generally have characteristics similar to
both debt and equity securities. The value of convertible securities tends to
decline as interest rates rise and, because of the conversion feature, tends to
vary with fluctuations in the market value of the underlying equity security.
Convertible securities ordinarily provide a stream of income with generally
higher yields than those of common stocks of the same or similar issuers.
Convertible securities generally rank senior to common stock in a corporation's
capital structure but are usually subordinated to comparable nonconvertible
securities. Convertible securities generally do not participate directly in any
dividend increases or decreases of the underlying equity security although the
market prices of convertible securities may be affected by any such dividend
changes or other changes in the underlying equity security.

The Portfolio may invest money market securities including securities issued or
guaranteed by the U.S. government, its agencies or its instrumentalities, prime
commercial paper, certificates of deposit, bankers' acceptances or other
obligations of certain domestic banks and repurchase agreements. Money market
securities generally have low market risk and credit risk but also generally
have a low potential for total investment return.

The Portfolio may invest up to 25% of its total assets, based on market value at
the time of each investment, in securities of foreign issuers. Such investments
include certain risks not typically associated with investments in U.S.
securities. See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures contracts which may
subject the Portfolio to additional risks. See "Investment Practices -- Using
Options, Futures Contracts and Options on Futures Contracts."

                                       31
<PAGE>   34

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

Because of the fully managed approach of the Portfolio, the Portfolio's turnover
rate may be greater than other portfolios and result in increased transaction
costs, including higher brokerage charges, which may adversely impact the
Portfolio's performance.

                               COMSTOCK PORTFOLIO

The investment objective of the Comstock Portfolio is to seek capital growth and
income through investments in equity securities, including common stocks,
preferred stocks and securities convertible into common and preferred stocks.
There are risks inherent in all investments in securities; accordingly, there
can be no assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing in equity securities, consisting
principally of common stocks. Common stocks are shares of a corporation or other
entity that entitle the holder to a pro rata share of the profits of the
corporation, if any, without preference over any other class of securities,
including such entity's debt securities, preferred stock and other senior equity
securities. Common stock usually carries with it the right to vote and
frequently an exclusive right to do so.

While the Portfolio invests principally in common stocks, the Portfolio may
invest in preferred stock and securities convertible into common and preferred
stocks. Preferred stock generally has a preference as to dividends and
liquidation over an issuer's common stock but ranks junior to debt securities in
an issuer's capital structure. Unlike interest payments on debt securities,
preferred stock dividends are payable only if declared by the issuer's board of
directors. Preferred stock also may be subject to optional or mandatory
redemption provisions. A convertible security is a bond, debenture, note,
preferred stock, warrant or other security that may be converted into or
exchanged for a prescribed amount of common stock or other equity security of
the same or a different issuer within a particular period of time at a specified
price or formula. A convertible security generally entitles the holder to
receive interest paid or accrued on debt securities or the dividend paid on
preferred stock until the convertible security matures or is redeemed, converted
or exchanged. Before conversion, convertible securities generally have
characteristics similar to both debt and equity securities. The value of
convertible securities tends to decline as interest rates rise and, because of
the conversion feature, tends to vary with fluctuations in the market value of
the underlying equity security. Convertible securities ordinarily provide a
stream of income with generally higher yields than those of common stock of the
same or similar issuers. Convertible securities generally rank senior to common
stock in a corporation's capital structure but are usually subordinated to
comparable nonconvertible securities. Preferred stocks and convertible
securities generally do not participate directly in any dividend increases or
decreases of the underlying equity security although the market prices of
preferred stocks and convertible securities may be affected by any such dividend
changes or other changes in the underlying equity security.

In selecting securities for investment, the Portfolio will focus primarily on
the security's potential for capital growth and income. The Portfolio emphasizes
a "value" style of investing seeking well-established, undervalued companies.
The Portfolio's investment adviser generally seeks to identify companies that
are undervalued and have identifiable factors that might lead to improved
valuations. This catalyst could come from within the company in the form of new
management, operational enhancements, restructurings or reorganization. It could
also be an external factor, such as an improvement in industry conditions or a
regulatory change. The Portfolio's style presents the risk that the valuations
never improve or that the returns on "value" equity securities are less than
returns on other styles of investing or the overall stock market. The Portfolio
may invest in issuers of small-, medium- or large-capitalization companies. The
securities of small- or medium-sized companies may be subject to more abrupt or
erratic market movements than securities of larger companies or the market
averages in general. In addition, such companies typically are subject to a
greater degree of change in earnings and business prospects than are larger
companies. Thus, the Portfolio may be subject to greater investment risk than
that assumed through investment in the equity securities of larger-
capitalization companies.

The Portfolio may dispose of a security whenever, in the opinion of the
Portfolio's investment adviser, factors indicate it is desirable to do so. Such
factors include change in economic or market factors in general or with respect
to a particular industry, a change in the market trend or other factors
affecting

                                       32
<PAGE>   35

an individual security, changes in the relative market performance or
appreciation possibilities offered by individual securities and other
circumstances bearing on the desirability of a given investment.

The Portfolio generally holds up to 10% of its total assets in high-quality
short-term debt securities and in investment grade corporate debt securities in
order to provide liquidity. High-quality short-term debt investments include
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities, prime commercial paper, certificates of deposit, bankers'
acceptances and other obligations of domestic banks having total assets of at
least $500 million and repurchase agreements. Investment grade corporate debt
securities include securities rated BBB or better by Standard & Poor's ("S&P")
or rated Baa or better by Moody's Investors Service, Inc. ("Moody's") or unrated
securities judged by the investment adviser to be of comparable quality. A more
complete description of security ratings is contained in the appendix to this
prospectus. The market prices of such debt securities generally vary inversely
with changes in prevailing interest rates.

The Portfolio may invest up to 15% of its total assets in securities of foreign
issuers. Such investments include certain risks not typically associated with
investments in U.S. securities. See "Investment Practices -- Foreign
Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                           DOMESTIC INCOME PORTFOLIO

The primary investment objective of the Domestic Income Portfolio is to seek
current income. When consistent with the primary investment objective, capital
appreciation is a secondary investment objective. There are risks inherent in
all investments in securities; accordingly, there can be no assurance that the
Portfolio will achieve its investment objectives.

The Portfolio's investment adviser seeks to achieve these investment objectives
by investing primarily in a diversified portfolio of income securities,
including convertible and non-convertible debt securities and preferred stocks.
The Portfolio may invest in investment grade securities and lower-rated and
unrated securities. Under normal market conditions, the Portfolio invests at
least 80% of its total assets in income securities rated at the time of purchase
B or higher by S&P or rated B or higher by Moody's or unrated securities judged
by the Portfolio's investments adviser to be of comparable quality. Securities
rated BB or below by S&P or Ba or below by Moody's or unrated securities of
comparable quality are commonly referred to as "junk bonds" and involve special
risks as compared to investments in higher-grade securities. See "Risks of Lower
Grade Securities" below.

In general, the prices of income securities vary inversely with interest rates.
If interest rates rise, income security prices generally fall; if interest rates
fall, income security prices generally rise. In general, longer-maturity income
securities offer higher yields than shorter-maturity income securities, all
other factors, including credit quality, being equal; however, for a given
change in interest rates, longer-maturity income securities generally fluctuate
more in price (gaining or losing more in value) than shorter-maturity income
securities. While the Portfolio has no policy limiting the maturities of the
income securities in which it may invest, the Portfolio's investment adviser
seeks to moderate market risk by generally maintaining a portfolio duration
within a range of four to six years. Duration is a measure of the expected life
of an income security that was developed as an alternative to the concept of
"term to maturity." Duration incorporates an income security's yield, coupon
interest payments, final maturity and call features into one measure. A duration
calculation looks at the present value of a security's entire payment stream
whereas term to maturity is based solely on the date of a security's final
principal repayment.

The higher yields sought by the Portfolio are generally obtainable from
securities rated in the lower categories by recognized rating services or
unrated securities of comparable quality. These securities may be issued in
connection with corporate restructurings, such as leveraged buyouts, mergers,
acquisitions, debt recapitalization or similar events. These securities are
often issued by smaller, less creditworthy companies or companies with
substantial debt and may include financially troubled companies or companies in
default or in

                                       33
<PAGE>   36

restructuring. Lower-grade securities often are subordinated to the prior claims
of banks and other senior lenders. Lower-grade securities are regarded by the
rating agencies as predominately speculative with respect to the issuer's
continuing ability to make principal and interest payments. The ratings of S&P
and Moody's represent their opinions of the quality of the securities they
undertake to rate, but not the market risk of such securities. It should be
emphasized, however, that ratings are general and are not absolute standards of
quality. Consequently, securities with the same maturity, coupon and rating may
have different yields while securities of the same maturity and coupon with
different ratings may have the same yield. See "Risks of Lower-Grade Securities"
below.

In purchasing securities for the Portfolio, the investment adviser considers,
among other thing, the security's current income potential, the rating assigned
to the security, the issuer's experience and managerial strength, the financial
soundness of the issuer and the outlook of its industry, changing financial
condition, borrowing requirements or debt maturity schedules, regulatory
concerns, and responsiveness to changes in business conditions and interest
rates. The Portfolio's investment adviser also may consider relative values
based on anticipated cash flow, interest or dividend coverage, balance sheet
analysis, and earnings prospects. The investment adviser evaluates each
individual income security for credit quality and value and attempts to identify
higher-yielding securities of companies whose financial condition has improved
since the issuance of such securities or is anticipated to improve in the
future. Because of the number of investment considerations involved in investing
in medium- and lower-grade securities, achievement of the Portfolio's investment
objectives may be more dependent upon the investment adviser's credit analysis
than is the case with investing solely in higher-grade securities.

The Portfolio may invest in securities not producing immediate cash income when
their effective yield over comparable instruments producing cash income make
these investments attractive. Prices on non-cash-paying instruments may be more
sensitive to changes in the issuer's financial condition, fluctuation in
interest rates and market demand/supply imbalances than cash-paying securities
with similar credit ratings, and thus may be more speculative. In addition, the
accrued interest income earned on such instruments is included in investment
company taxable income, thereby increasing the required minimum distributions to
shareholders without providing the corresponding cash flow with which to pay
such distributions. The Portfolio's investment adviser will weigh these concerns
against the expected total returns from such instruments.

The Portfolio also may purchase or sell U.S. government securities on a forward
commitment basis. See "When-Issued and Delayed Delivery" below.

Although the Portfolio invests primarily in domestic income securities, the
Portfolio may invest up to 25% of its total assets based on the market value at
the time of investment in securities of foreign issuers. Such investments
include certain risks not typically associated with investments in U.S.
securities. See "Investment Practices -- Foreign Securities."

Income securities in which the Portfolio may invest include the following:

STRAIGHT INCOME SECURITIES. These include bonds and other debt obligations which
bear a fixed or variable rate of interest payable at regular intervals and have
a fixed or resettable maturity date, and preferred stock, which generally has a
fixed or variable dividend rate (and, unlike interest on debt securities, such
dividends must be declared by the issuer's board of directors before becoming
payable) and may be subject to optional or mandatory redemption provisions. The
particular terms of such securities vary and may include features such as call
provisions and sinking funds.

PAY-IN-KIND INCOME SECURITIES. These pay interest in additional income
securities rather than in cash.

ZERO-COUPON SECURITIES. These bear no interest obligation but are issued at a
discount from their value at maturity. When held to maturity, their entire
return equals the difference between their issue price and their maturity value.
Interest is however accrued by the Portfolio each day for accounting and federal
income tax purposes.

ZERO-FIXED-COUPON SECURITIES. These are zero-coupon securities which convert on
a specified date to interest-bearing income securities.

The Portfolio may invest in securities rated below B by both S&P and Moody's,
common stocks or other equity securities and income securities on which interest
or dividends are not being paid when such investments are consistent with the
Portfolio's investment objectives or are acquired as part of a unit consisting
of a combination of income or equity

                                       34
<PAGE>   37

securities. The Portfolio will not purchase any such securities which will cause
more than 20% of its total assets to be so invested or which would cause more
than 10% of its total assets to be invested in common stocks or other equity
securities. Equity securities as referred to herein do not include preferred
stocks (which the Portfolio considers income securities). This limitation does
not require the Portfolio to sell a portfolio security because its rating has
been changed.

Securities rated below B by both S&P and Moody's often include debt obligations
or other securities of companies that are financially troubled, in default or
are in bankruptcy or reorganization. Securities of such companies are usually
available at a deep discount from the face value of the instrument. The
Portfolio may invest in deep discount securities when the Portfolio's investment
adviser believes that existing factors are likely to restore the company to a
healthy financial condition. Such factors include a restructuring of debt,
management changes, existence of adequate assets, or other unusual
circumstances.

A security purchased at a deep discount may pay a very high effective yield. In
addition, if the financial condition of the issuer improves, the underlying
value of the security may increase, resulting in a capital gain. If the company
defaults on its obligations or remains in default, or if the plan of
reorganization is insufficient for debtholders, the deep discount securities may
stop generating income and lose value or become worthless. The Portfolio's
investment adviser will balance the benefits of deep discount securities with
their risks. While a diversified portfolio may reduce the overall impact of a
deep discount security that is in default or loses its value, the risk cannot be
eliminated.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

RISKS OF LOWER-GRADE SECURITIES. Securities which are in the lower-grade
categories generally offer a higher current yield than is offered by
higher-grade securities of similar maturities, but they also generally involve
greater risks, such as greater credit risk, greater market risk, greater
liquidity concerns and potentially greater manager risk. Investors should
carefully consider the risks of owning shares of a portfolio which invests in
lower-grade securities before investing in the Portfolio.

Credit risk relates to the issuer's ability to make timely payment of interest
and principal when due. Lower-grade securities are considered more susceptible
to nonpayment of interest and principal or default than higher-grade securities.
Increases in interest rates or changes in the economy may significantly affect
the ability of issuers of lower-grade debt securities to pay interest and to
repay principal, to meet projected financial goals or to obtain additional
financing. In the event that an issuer of securities held by the Portfolio
experiences difficulties in the timely payment of principal and interest and
such issuer seeks to restructure the terms of its borrowings, the Portfolio may
incur additional expenses and may determine to invest additional assets with
respect to such issuer or the project or projects to which the Portfolio's
securities relate. Further, the Portfolio may incur additional expenses to the
extent that it is required to seek recovery upon a default in the payment of
interest or the repayment of principal on its portfolio holdings, and the
Portfolio may be unable to obtain full recovery on such amounts.

Market risk relates to changes in market value of a security that occur as a
result of variation in the level of prevailing interest rates and yield
relationships in the debt securities market and as a result of real or perceived
changes in credit risk. The value of the Portfolio's investments can be expected
to fluctuate over time. When interest rates decline, the value of a portfolio
invested in fixed income securities generally can be expected to rise.
Conversely, when interest rates rise, the value of a portfolio invested in fixed
income securities generally can be expected to decline. However, the secondary
market prices of lower-grade debt securities generally are less sensitive to
changes in interest rate and are more sensitive to general adverse economic
changes or specific developments with respect to the particular issuers than are
the secondary market prices of higher-grade debt securities. A significant
increase in interest rates or a general economic downturn could severely disrupt
the market for lower-grade securities and adversely affect the market value of
such securities. Such events also could lead to a higher incidence of default by
issuers of lower-grade securities as compared with higher-grade securities. In
addition, changes in credit risks, interest rates, the credit markets or periods
of general economic uncertainty can be expected to result in increased
volatility in the market price of the lower-grade securities in the Portfolio
and thus in the net asset value of the Portfolio. Adverse publicity and investor
perceptions, whether or not based on

                                       35
<PAGE>   38

rational analysis, may affect the value and liquidity of lower-grade securities.

The markets for lower-grade securities may be less liquid than the markets for
higher-grade securities. Liquidity relates to the ability of a fund to sell a
security in a timely manner at a price which reflects the value of that
security. To the extent that there is no established retail market for some of
the lower-grade securities in which the Portfolio may invest, trading in such
securities may be relatively inactive. Prices of lower-grade securities may
decline rapidly in the event a significant number of holders decide to sell.
Changes in expectations regarding an individual issuer or lower-grade securities
generally could reduce market liquidity for such securities and make their sale
by the Portfolio more difficult, at least in the absence of price concessions.
The effects of adverse publicity and investor perceptions may be more pronounced
for securities for which no established retail market exists as compared with
the effects on securities for which such a market does exist. An economic
downturn or an increase in interest rates could severely disrupt the market for
such securities and adversely affect the value of outstanding securities or the
ability of the issuers to repay principal and interest. Further, the Portfolio
may have more difficulty selling such securities in a timely manner and at their
stated value than would be the case for securities for which an established
retail market does exist.

The Portfolio's investment adviser is responsible for determining the net asset
value of the Portfolio, subject to the supervision of the Portfolio's Board of
Trustees. During periods of reduced market liquidity and in the absence of
readily available market quotations for lower-grade securities held in the
Portfolio's portfolio, the ability of the Portfolio's investment adviser to
value the Portfolio's securities becomes more difficult and the investment
adviser's use of judgment may play a greater role in the valuation of the
Portfolio's securities due to the reduced availability of reliable objective
data.

New or proposed laws may have an impact on the market for lower-grade
securities. The Portfolio's investment adviser is unable at this time to predict
what effect, if any, legislation may have on the market for lower-grade
securities.

Special tax considerations are associated with investing in certain lower-grade
securities, such as zero coupon or pay-in-kind securities. The Portfolio accrues
income on these securities prior to the receipt of cash payments. The Portfolio
must distribute substantially all of its income to its shareholders to qualify
for pass-through treatment under federal income tax law and may, therefore, have
to dispose of its portfolio securities to satisfy distribution requirements.

The Portfolio will rely on its investment adviser's judgment, analysis and
experience in evaluating the creditworthiness of an issue. The amount of
available information about the financial condition of certain lower-grade
issuers may be less extensive than other issuers. In its analysis, the
Portfolio's investment adviser may consider the credit ratings of S&P and
Moody's in evaluating securities although the investment adviser does not rely
primarily on these ratings. Ratings evaluate only the safety of principal and
interest payments, not the market value risk. Additionally, ratings are general
and not absolute standards of quality, and credit ratings are subject to the
risk that the creditworthiness of an issuer may change and the rating agencies
may fail to change such ratings in a timely fashion. A rating downgrade does not
require the Portfolio to dispose of a security. The Portfolio's investment
adviser continuously monitors the issuers of securities held in the Portfolio.
Because of the number of investment considerations involved in investing in
lower-grade securities, achievement of the Portfolio's investment objectives may
be more dependent upon the investment adviser's credit analysis than is the case
with investing in higher-grade securities.


The table below sets forth the percentages of the Portfolio's assets invested
during the fiscal year ended December 31, 1999 in the various S&P's and Moody's
rating categories and in unrated securities determined by the Portfolio's
investment adviser to be of comparable quality. The percentages are based on the
dollar-weighted average of credit ratings of all

securities held by the Portfolio during the 1999 fiscal year computed on a

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase or sell
U.S. government securities on a "when-issued" or "delayed delivery" basis
("Forward Commitments"). These transactions occur when securities are purchased
or sold by the Portfolio with payment and delivery taking place in the future,
frequently a month or more after such transaction. The price is fixed on the
date of the commitment, and the seller continues to accrue interest on the
securities covered by the Forward Commitment until delivery and payment take
place. At the time of settlement, the market value of the securities may be more
or less than the purchase or sale price. The Portfolio may either settle a
Forward Commitment by taking delivery of the securities or may either resell or
repurchase a Forward Commitment on or before the settlement date in which event
the Portfolio may reinvest the proceeds in another Forward Commitment. These
transactions are subject to market risk as the value or yield of a security at
delivery may be more or less than the purchase price or the yield generally
available on securities when delivery occurs. When engaging in Forward
Commitments, the Portfolio relies on the other party to complete the
transaction, should the other party fail to do so, the Portfolio might lose a
purchase or sale opportunity that could be more advantageous than alternative
opportunities at the time of the failure. The Portfolio maintains a segregated
account (which is marked to market daily) of cash or liquid portfolio securities
with the Portfolio's custodian in an aggregate amount equal to the amount of its
commitment as long as the obligation to purchase or sell continues.

                           EMERGING GROWTH PORTFOLIO


The investment objective of the Emerging Growth Portfolio is to seek capital
appreciation. Any ordinary income received from securities owned by the
Portfolio is entirely incidental to the Portfolio's investment objective of
capital appreciation. There are risks inherent in all investments in securities;
accordingly, there can be no assurance that the Portfolio will achieve its
investment objective.



Under normal conditions, the Portfolio's investment adviser seeks to achieve the
Portfolio's investment objective by investing at least 65% of the Portfolio's
total assets in common stocks of emerging growth companies. Emerging growth
companies are those companies in the early stages of their life cycles that the
Portfolio's investment adviser believes have the potential to become major
enterprises. Investments in such companies may offer greater opportunities for
growth of capital than larger, more established companies, but also may involve
certain special risks. Emerging growth companies often have limited product
lines, markets, distribution channels or financial resources, and they may be
dependent upon one or a few key people for management. The securities of such
companies may be subject to more abrupt or erratic market movements than
securities of larger, more established companies or the market averages in
general.


The Portfolio does not limit its investments to any single group or type of
security. The Portfolio may invest in securities involving special situations,
such as new management, special products and techniques, unusual developments,
mergers or liquidations. Investments in unseasoned companies and special
situations often involve much greater risks than are inherent in other types of
investments, because securities of such companies may be more likely to
experience unexpected fluctuations in price.

The Portfolio's primary approach is to seek what the Portfolio's investment
adviser believes to be unusually attractive growth investments on an individual
company basis. The Portfolio may invest in securities that have above average
volatility of price movement. Because prices of common stocks and other
securities fluctuate, the value of an investment in the Portfolio will vary
based upon the Portfolio's investment performance. The Portfolio attempts to
reduce overall exposure to risk from declines in securities prices by spreading
its investments over many different companies in a variety of industries. There

                                       37
<PAGE>   40

is, however, no assurance that the Portfolio will be successful in achieving its
objective.

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so.

While the Portfolio invests principally in common stocks, the Portfolio may
invest to a limited extent in other securities such as preferred stocks,
convertible securities and warrants. Preferred stock generally has a preference
as to dividends and liquidation over an issuer's common stock but ranks junior
to debt securities in an issuer's capital structure. Unlike interest payments on
debt securities, preferred stock dividends are payable only if declared by the
issuer's board of directors. Preferred stock also may be subject to optional or
mandatory redemption provisions. Generally, warrants are securities that may be
exchanged for a prescribed amount of common stock or other equity security of
the issuer within a particular period of time at a specified price or in
accordance with a specified formula.

The Portfolio may invest up to 20% of its total assets in securities of foreign
issuers. Such investments include certain risks not typically associated with
investments in U.S. securities. See "Investment Practices -- Foreign
Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and related options which may subject the
Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                              ENTERPRISE PORTFOLIO

The investment objective of the Enterprise Portfolio is to seek capital
appreciation through investments in securities believed by the Portfolio's
investment adviser to have above average potential for capital appreciation. Any
income received on securities owned by the Portfolio is entirely incidental to
the Portfolio's investment objective of capital appreciation. There are risks
inherent in all investments in securities; accordingly, there can be no
assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing primarily in common stocks which
it believes have above-average potential for capital appreciation. The
Portfolio's primary approach is to seek what the Portfolio's investment adviser
believes to be unusually attractive growth investments on an individual company
basis. The Portfolio may invest in securities that have above average volatility
of price movement. Because prices of common stocks and other securities
fluctuate, the value of an investment in the Portfolio will vary. The Portfolio
attempts to reduce overall exposure to risk from declines in securities prices
by spreading its investments over many different companies in a variety of
industries.

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so.

While the Portfolio invests principally in common stocks, the Portfolio may
invest in preferred stocks and warrants. Preferred stock generally has a
preference as to dividends and liquidation over an issuer's common stock but
ranks junior to debt securities in an issuer's capital structure. Unlike
interest payments on debt securities, preferred stock dividends are payable only
if declared by the issuer's board of directors. Preferred stock also may be
subject to optional mandatory redemption provisions. Generally, warrants are
securities that may be exchanged for a prescribed amount of common stock or
other equity security of the issuer within a particular period of time at a
specified price or in accordance with a specific formula.

In selecting securities for investment, the Portfolio will generally focus on
common stocks of "growth" companies, including companies with new products,
services or processes. The investment adviser seeks such securities which it
believes offer a combination of strong business fundamentals at an attractive
price. Growth companies generally include those companies

                                       38
<PAGE>   41

with established records of growth in sales or earnings that the Portfolio's
investment adviser believes are entering into a growth cycle in their respective
businesses, with the expectation that the stock of such companies will increase
in value. Stocks of different types, such as "growth" stocks or "value" stocks,
tend to shift in and out of favor depending on market and economic conditions.
Thus, the value of the Portfolio's investments in "growth" stocks will vary and
may at times be lower or higher than that of other types of funds. The market
values of "growth" common stocks may be more volatile than other types of
investments. The Portfolio may invest in companies generating or applying new
technologies, new or improved distribution techniques or new services, which
companies may benefit from changing consumer demands or lifestyles, or companies
that have projected earnings in excess of the average for their sector or
industry. In each case, such companies have prospects that the Portfolio's
investment adviser believes are favorable for above-average capital
appreciation. The Portfolio also may focus its investments on stocks of
companies in cyclical industries during periods when their securities appear
attractive for capital appreciation.

The companies in which the Portfolio invests may be in any market capitalization
range, provided the Portfolio's investment adviser believes the investment is
consistent with the Portfolio's objective. The securities of small- or
medium-sized companies may be subject to more abrupt or erratic market movements
than securities of larger companies or the market averages in general. In
addition, such companies typically are subject to a greater degree of change in
earnings and business prospects than are larger companies. Thus, to the extent
the Portfolio invests in small- and medium-sized companies, the Portfolio may be
subject to greater investment risk than that assumed through investment in the
equity securities of larger-capitalization companies.

The Portfolio may dispose of a security whenever, in the opinion of the
Portfolio's investment adviser, factors indicate it is desirable to do so. Such
factors include change in economic or market factors in general or with respect
to a particular industry, a change in the market trend or other factors
affecting an individual security, changes in the relative market performance or
appreciation possibilities offered by individual securities and other
circumstances bearing on the desirability of a given investment.

The Portfolio generally holds a portion of its assets in investment grade
short-term debt securities and in investment grade corporate debt securities in
order to provide liquidity. Investment grade short-term debt investments include
securities issued or guaranteed by the U.S. government, its agencies or its
instrumentalities, prime commercial paper, certificates of deposit, bankers'
acceptances and other obligations of domestic banks having total assets of at
least $500 million and repurchase agreements. Investment grade corporate debt
securities include securities rated BBB or better by Standard & Poor's ("S&P")
or Baa or higher by Moody's Investors Service, Inc. ("Moody's"). A more complete
description of security ratings is contained in the appendix to this prospectus.
The market prices of such debt securities generally vary inversely with changes
in prevailing interest rates.

The Portfolio may invest up to 10% of its total assets, based on market value at
the time of each investment, in securities of foreign issuers. Such investments
include certain risks not typically associated with investments in U.S.
securities. See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                            GLOBAL EQUITY PORTFOLIO

The investment objective of the Global Equity Portfolio is to seek long-term
growth of capital through investments in an internationally diversified
portfolio of equity securities of companies of any nation including the United
States. There are risks inherent in all investments in securities; accordingly,
there can be no assurance that the Portfolio will achieve its investment
objective.

The Portfolio's investment adviser seeks to achieve the investment objective by
investing in an internationally diversified portfolio of equity securities,
including common stocks, preferred stocks and warrants or options to acquire
such securities, based upon the evaluation by the Portfolio's investment

                                       39
<PAGE>   42

adviser of economic and market trends and the anticipated relative capital
growth opportunities available from a particular country or security. Under
normal market conditions, the Portfolio invests at least 65% of its total assets
in securities of issuers of at least three countries (including the United
States.)

The Portfolio's investment adviser, subject to the direction of the Portfolio's
Board of Trustees, provides the Portfolio with an overall investment program
consistent with the Portfolio's objective and policies. The Portfolio's
investments may be shifted among the world's various capital markets, including
developed and undeveloped countries, and among different types of securities in
accordance with the investment adviser's ongoing analysis of economic or market
trends, developments affecting the markets and securities in which the Portfolio
may invest and the anticipated relative capital growth opportunities available
from a particular country or security.

In selecting non-U.S. investments for the Portfolio, the Portfolio's investment
adviser uses a "top-down" approach that emphasizes country and sector selection
and weighting rather than individual security selection. This approach reflects
the investment adviser's philosophy for this Portfolio that a broad selection of
securities representing exposure to world markets based upon the economic
outlook and current valuation levels for each country and certain sectors is an
effective way to maximize the return and minimize the risk associated with
global investment.

The Portfolio's investment adviser determines country and sector allocations for
the Portfolio on an ongoing basis. The Portfolio will invest in the United
States and other industrialized countries throughout the world that comprise the
Morgan Stanley Capital International World Index. In addition, the Portfolio may
invest a portion of its assets in securities of certain developing or emerging
markets countries.

By analyzing a variety of macroeconomic and political factors, the Portfolio's
investment adviser develops fundamental projections on interest rates,
currencies, corporate profits and economic growth for each country or sector.
These country projections are then used to determine what the investment adviser
believes to be a fair value for the stock market of each country or sector.
Discrepancies between actual value and fair value, as determined by the
investment adviser, provide an expected return for each stock market. The
expected return is adjusted by currency return expectations derived from the
investment adviser's purchasing-power parity exchange rate model to arrive at an
expected total return in U.S. dollars. The final country and sector allocation
decision is then reached by considering the expected total return in light of
various considerations such as market size, volatility, liquidity and country
risk.

Within a particular country or sector, investments are made through the purchase
of equity securities which, in the aggregate, replicate a broad market index for
that country or sector, which in most cases will be the Morgan Stanley Capital
International Index ("MSCI Index") for the particular country or sector. The
MSCI Indices measure the performance of stock markets worldwide and are based on
the share prices of companies listed on the local stock exchange of the
specified country or countries within a specified region. The combined market
capitalization of companies in these indices represent approximately 60% of the
aggregate market value of the covered stock exchanges. Companies included in the
MSCI Index for a country replicate the industry composition of the local market
and are a representative sampling of large-, medium- and small-companies,
subject to liquidity. Non-domiciled companies traded on the country's local
exchange and companies with restricted float due to dominant shareholders or
cross-ownership are avoided. The Portfolio's investment adviser may overweight
or underweight an industry segment of a particular index if it concludes this
would be advantageous to the Portfolio.

The Portfolio may invest in equity securities including common stocks, preferred
stocks, warrants or options to acquire such securities and depository receipts.
Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so. Preferred stock generally has a preference as to dividends and
liquidation over an issuer's common stock but ranks junior to debt securities in
an issuer's capital structure. Unlike interest payments on debt securities,
preferred stock dividends are payable only if declared by the issuer's board of
directors. Preferred stock also may be subject to optional or mandatory
redemption provisions. Generally, warrants or options to acquire equity
securities are securities that may be exchanged for a prescribed amount of such

                                       40
<PAGE>   43

equity securities of the issuer within a particular period of time at a
specified price or in accordance with a specified formula.

The Portfolio may invest in issuers of small-, medium- or large-capitalization
companies. The securities of small- or medium-sized companies may be subject to
more abrupt or erratic market movements than securities of larger companies or
the market averages in general. In addition, such companies typically are
subject to a greater degree of change in earnings and business prospects than
are larger companies. Thus, to the extent the Portfolio invests in small- and
medium-sized companies, the Portfolio may be subject to greater investment risk
than that assumed through investment in the equity securities of
larger-capitalization companies.

The Portfolio may purchase foreign securities in the form of American Depositary
Receipts ("ADRs") and European Depositary Receipts ("EDRs") or other securities
representing underlying shares of foreign companies. These securities are not
necessarily denominated in the same currency as the underlying securities but
generally are denominated in the currency of the market in which they are
traded. ADRs are receipts typically issued by an American bank or trust company
which evidence ownership of underlying securities issued by foreign
corporations. ADRs are publicly traded on exchanges or over-the-counter in the
United States and are issued through "sponsored" or "unsponsored" arrangements.
In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay
some or all of the depositary's transaction fees, whereas under an unsponsored
arrangement, the foreign issuer assumes no obligations and the depositary's
transaction fees are paid by the ADR holders. In addition, less information
generally is available for an unsponsored ADR than a sponsored ADR, and
financial information about a company may not be as reliable for an unsponsored
ADR as it is for a sponsored ADR. The Portfolio may invest in ADRs through both
sponsored and unsponsored arrangements. EDRs are receipts issued in Europe by
banks or depositaries which evidence similar ownership arrangements.

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures contracts which may
subject the Portfolio to additional risks. See "Investment Practices -- Using
Options, Futures Contracts and Options in Futures Contracts."

The Portfolio generally holds a portion of its assets in short-term debt
securities in order to provide liquidity. Short-term debt securities include
securities issued or guaranteed by the U.S. government or foreign governments,
their agencies or instrumentalities, prime commercial paper, certificates of
deposit, bankers' acceptances and other obligations of banks having total assets
of at least $500 million and repurchase agreements.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

RISK FACTORS OF INVESTING IN SECURITIES OF FOREIGN ISSUERS. An investment in the
Portfolio involves risks similar to those of investing in foreign securities
generally. The Portfolio invests in securities denominated in U.S. dollars and
in currencies other than U.S. dollars. The percentage of assets invested in
securities of a particular country or denominated in a particular currency will
vary in accordance with the investment adviser's assessment of the relative
yield, growth potential and the relationship of a country's currency to the U.S.
dollar, which is based upon such factors as fundamental economic strength,
credit quality and interest rate trends. Investments in foreign securities
present certain risks not ordinarily associated with investments in securities
of U.S. issuers. These risks include fluctuations in foreign currency exchange
rates, political, economic or legal developments (including war or other
instability, expropriation of assets, nationalization and confiscatory
taxation), imposition of foreign exchange limitations (including currency
blockage), withholding taxes on dividend or interest payments or capital
transactions or other restrictions, higher transaction costs (including higher
brokerage, custodial and settlement costs and currency translation costs) and
possible difficulty in enforcing contractual obligations or taking judicial
action. Also, foreign securities may not be as liquid and may be more volatile
than comparable domestic securities.

In addition, there often is less publicly available information about many
foreign issuers, and issuers of foreign securities are subject to different,
often less comprehensive, auditing, accounting, financial reporting and
disclosure requirements than domestic issuers. There is generally less
government regulation of stock exchanges, brokers and listed companies abroad
than in the U.S., and, with respect to certain foreign countries, there is a
possibility of expropriation or confiscatory taxation, or diplomatic

                                       41
<PAGE>   44

developments which could affect investment in those countries. Because there is
usually less supervision and governmental regulation of exchanges, brokers and
dealers than there is in the U.S., the Portfolio may experience settlement
difficulties or delays not usually encountered in the U.S.

Delays in making trades in foreign securities relating to volume constraints,
limitations or restrictions, clearance or settlement procedures, or otherwise
could impact yields and result in temporary periods when assets are not fully
invested or attractive investment opportunities are foregone.

The Portfolio's investments in securities of developing or emerging markets are
subject to greater risks than the Portfolio's investments in securities of
developed countries since emerging markets tend to have economic structures that
are less diverse and mature and political systems that are less stable than
developed countries.

Since the Portfolio invests in securities denominated or quoted in currencies
other than the U.S. dollar, the Portfolio will be affected by changes in foreign
currency exchange rates (and exchange control regulations) which affect the
value of securities in the Portfolio and the income and appreciation or
depreciation of Portfolio investments. Changes in foreign currency exchange
ratios relative to the U.S. dollar will affect the U.S. dollar value of the
Portfolio's assets denominated in that currency and the Portfolio's yield on
such assets. In addition, the Portfolio will incur costs in connection with
conversions between various currencies. The Portfolio's foreign currency
exchange transactions generally will be conducted on a spot basis (that is, cash
basis) at the spot rate for purchasing or selling currency prevailing in the
foreign currency exchange market. The Portfolio purchases and sells foreign
currency on a spot basis in connection with the settlement of transactions in
securities traded in such foreign currency. The Portfolio does not purchase and
sell foreign currencies as an investment.

The Portfolio also may enter into contracts with banks or other foreign currency
brokers or dealers to purchase or sell foreign currencies at a future date
("forward contracts") and purchase and sell foreign currency futures contracts
to hedge against changes in foreign currency exchange rates. A foreign currency
forward contract is a negotiated agreement between the contracting parties to
exchange a specified amount of currency at a specified future time at a
specified rate. The rate can be higher or lower than the spot rate between the
currencies that are the subject of the contract.

The Portfolio may attempt to hedge against changes in the value of the U.S.
dollar in relation to a foreign currency by entering into a forward contract for
the purchase or sale of the amount of foreign currency invested or to be
invested, or by buying or selling a foreign currency futures contract for such
amount. Futures contracts are described below under the heading "Investment
Practices -- Using Options, Futures Contracts and Options in Futures Contracts."
Such hedging strategies may be employed before the Portfolio purchases a foreign
security traded in the hedged currency which the Portfolio anticipates acquiring
or between the date the foreign security is purchased or sold and the date on
which payment therefor is made or received. Hedging against a change in the
value of a foreign currency in the foregoing manner does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Furthermore, such hedging transactions reduce
or preclude the opportunity for gain if the value of the hedged currency should
move in the direction opposite to the hedged position. Unanticipated changes in
currency prices may result in poorer overall performance for the Portfolio than
if it had not entered into such contracts.

The Portfolio's custodian will place cash or liquid securities in a segregated
account having a value equal to the aggregate amount of the Portfolio's
commitments under forward contracts. If the value of the securities placed in
the segregated account declines, additional cash or securities are placed in the
account on a daily basis so that the value of the account equals the amount of
the Portfolio's commitments with respect to such contracts. As an alternative to
maintaining all or part of the segregated account, the Portfolio may purchase a
call option permitting the Portfolio to purchase the amount of foreign currency
by a forward sale contract at a price no higher than the forward contract price
or the Portfolio may purchase a put option permitting the Portfolio to sell the
amount of foreign currency subject to a forward purchase contract at a price as
high or higher than the forward contract price.

SHORT SALES The Portfolio may from time to time make short sales of securities
it owns or has the right to acquire through conversion or exchange of other
securities it owns. A short sale is "against the box"

                                       42
<PAGE>   45

to the extent that the Portfolio contemporaneously owns or has the right to
obtain at no added cost securities identical to those sold short. In a short
sale, the Portfolio does not immediately deliver the securities sold and does
not receive the proceeds from the sale. The Portfolio is required to recognize
gain from the short sale for federal income tax purposes at the time it enters
into the short sale, even though it does not receive the sales proceeds until it
delivers the securities. The Portfolio is said to have a short position in the
securities sold until it delivers the securities sold, at which time it receives
the proceeds of the sale. The Portfolio may not make short sales or maintain a
short position if to do so would cause more than 25% of its total assets, taken
at market value, to be held as collateral for such sales. To secure its
obligation to deliver the securities sold short, the Portfolio will deposit in
escrow in a separate account with its custodian an equal amount of the
securities sold short or securities convertible into or exchangeable for such
securities. The Portfolio may close out a short position by purchasing and
delivering an equal amount of the securities sold short, rather than by
delivering securities already held by the Portfolio, because it may want to
continue to receive interest and dividend payments on its investments that are
convertible into the securities sold short.

                              GOVERNMENT PORTFOLIO

The investment objective of the Government Portfolio is to seek to provide
investors with high current return consistent with preservation of capital.
There are risks inherent in all investments in securities; accordingly, there
can be no assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing at least 80% of the Portfolio's
total assets in debt securities issued or guaranteed by the U.S. government, its
agencies or its instrumentalities, including mortgage-related securities issued
or guaranteed by instrumentalities of the U.S. government. Under normal market
conditions, the Portfolio may invest up to 20% of its total assets in other
government-related securities, including privately issued mortgage-related and
mortgage-backed securities not issued or directly guaranteed by
instrumentalities of the U.S. government, privately issued certificates
representing "stripped" U.S. government or mortgage-related securities and
repurchase agreements fully collateralized by U.S. government securities. While
securities purchased for the Portfolio's investments may be issued or guaranteed
by the U.S. government, the shares issued by the Portfolio to investors are not
insured or guaranteed by the U.S. government, its agencies or its
instrumentalities or any other person or entity. For more information on the
Portfolio's investments, see "U.S. Government Securities" and "Government-
Related Securities" below.

The value of debt securities generally varies inversely with changes in
prevailing interest rates. If interest rates rise, debt security prices
generally fall; if interest rates fall, debt security prices generally rise.
Debt securities with longer maturities generally offer higher yields than debt
securities with shorter maturities assuming all other factors, including credit
quality, being equal. For a given change in interest rates, the market prices of
longer-maturity debt securities generally fluctuate more than the market prices
of shorter-maturity debt securities. While the Portfolio has no policy limiting
the maturities of the individual debt securities in which it may invest, the
Portfolio's investment adviser seeks to moderate market risk by generally
maintaining a portfolio duration of four to six years. Duration is a measure of
the expected life of a debt security that was developed as an alternative to the
concept of "term to maturity." Duration incorporates a debt security's yield,
coupon interest payments, final maturity and call features into one measure. A
duration calculation looks at the present value of a security's entire payment
stream whereas term to maturity is based solely on the date of a security's
final principal repayment.

The Portfolio may invest in mortgage-related or mortgage-backed securities. The
value of such securities tend to vary inversely with changes in prevailing
interest rates, but also are more susceptible to prepayment risk and extension
risk than other debt securities.

The Portfolio may purchase debt securities at a premium over the principal or
face value in order to obtain higher current income. The amount of any premium
declines during the term of the security to zero at maturity. Such decline
generally is reflected in the market price of the security and thus in the
Portfolio's net asset value. Any such decline is realized for accounting
purposes as a capital loss at maturity or upon resale. Prior to maturity or
resale, such decline in value could be offset, in whole or part, or increased by
changes in the value of the security due to changes in interest rate levels.

                                       43
<PAGE>   46

In order to hedge against changes in interest rates, the Portfolio may enter
into certain derivative transactions, such as the purchase or sell options,
futures contracts and options on such contracts and interest rate swaps or other
interest rate-related transactions. By using such strategies, the Portfolio
seeks to limit its exposure to adverse interest rate changes, but the Portfolio
also reduces its potential for capital appreciation on debt securities if
interest rates decline. The purchase and sale of such securities may result in a
higher portfolio turnover rate than if the Portfolio had not purchased or sold
such securities. See "Interest Rate Transactions" and "Investment Practices --
Using Options, Futures Contracts and Options on Futures Contracts."

The Portfolio also may purchase or sell U.S. government securities on a forward
commitment basis. See "When-Issued and Delayed Delivery Securities" below.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

The Portfolio intends to invest in U.S. Treasury securities and in securities
issued by at least four U.S. government agencies or instrumentalities in the
amounts necessary to permit the Accounts to meet certain diversification
requirements imposed by Section 817(h) of the Internal Revenue Code of 1986, as
amended (the "Code"), at the end of each quarter of the year (or within 30 days
thereafter). See "Dividends, Distributions and Taxes." In the event the
Portfolio does not meet the diversification requirements of Section 817(h) of
the Code, the policies funded by shares of the Portfolio will not be treated as
life insurance for federal income tax purposes and the owners of the policies
will be subject to taxation on their share of the dividends and distributions
paid by the Portfolio.

U.S. GOVERNMENT SECURITIES. Securities issued or guaranteed by the U.S.
government, its agencies or its instrumentalities include: (1) U.S. Treasury
obligations, which differ in their interest rates, maturities and times of
issuance: U.S. Treasury bills (maturity of one year or less), U.S. Treasury
notes (maturity of one to ten years), and U.S. Treasury bonds (generally
maturities of greater than ten years), including the principal components or the
interest components issued by the U.S. government under the Separate Trading of
Registered Interest and Principal Securities program (i.e. "STRIPS"), all of
which are backed by the full faith and credit of the U.S.; and (2) obligations
issued or guaranteed by U.S. government agencies or instrumentalities, including
government guaranteed mortgage-related securities, some of which are backed by
the full faith and credit of the U.S. Treasury, some of which are supported by
the right of the issuer to borrow from the U.S. government and some of which are
backed only by the credit of the issuer itself.

MORTGAGE-RELATED SECURITIES. Mortgage loans securing real property made by
banks, savings and loan institutions, and other lenders are often assembled into
pools. Interests in such pools may then be issued by private entities or also
may be issued or guaranteed by an agency or instrumentality of the U.S.
government. Interests in such pools are what this prospectus calls
"mortgage-related securities." Mortgage-related securities include, but are not
limited to, obligations issued or guaranteed by the Government National Mortgage
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC"). GNMA is a wholly owned
corporate instrumentality of the U.S. whose securities and guarantees are backed
by the full faith and credit of the U.S. FNMA, a federally chartered and
privately owned corporation, and FHLMC, a federal corporation, are
instrumentalities of the U.S. The securities and guarantees of FNMA and FHLMC
are not backed, directly or indirectly, by the full faith and credit of the U.S.
Although the Secretary of the Treasury of the U.S. has discretionary authority
to lend amounts to FNMA up to certain specified limits, neither the U.S.
government nor any agency thereof is obligated to finance FNMA's or FHLMC's
operations or to assist FNMA or FHLMC in any other manner. Securities of FNMA
and FHLMC include those issued in principal only or interest only components.

The yield and payment characteristics of mortgage-related securities differ from
traditional debt securities. Mortgage-related securities are characterized by
monthly payments to the holder, reflecting the monthly payments made by the
borrowers who received the underlying mortgage loans less fees paid to the
guarantor and the servicer of such mortgage loans. The payments to the holders
of mortgage-related securities (such as the Portfolio), like the payments on the
underlying mortgage loans, represent both principal and interest. Although the
underlying mortgage loans are for specified periods of time, such as 20 or 30
years, the borrowers can, and typically do, pay them off sooner. Thus, the
holders of mortgage-related securities

                                       44
<PAGE>   47

frequently receive prepayments of principal, in addition to the principal which
is part of the regular monthly payment. Faster or slower prepayments than
expected on underlying mortgage loans can dramatically alter the valuation and
yield-to-maturity of mortgage-related securities. The value of mortgage-related
securities, like traditional debt securities, tends to vary inversely with
changes in prevailing interest rates. Mortgage-related securities, however, may
benefit less than traditional debt securities from declining interest rates
because a property owner is more likely to refinance a mortgage which bears a
relatively high rate of interest during a period of declining interest rates.
This means some of the Portfolio's higher yielding securities might be converted
to cash, and the Portfolio will be forced to accept lower interest rates when
that cash is used to purchase new securities at prevailing interest rates. The
increased likelihood of prepayment when interest rates decline also limits
market price appreciation of mortgage-related securities. If the Portfolio buys
mortgage-related securities at a premium, mortgage foreclosures or mortgage
prepayments may result in a loss to the Portfolio of up to the amount of the
premium paid since only timely payment of principal and interest is guaranteed.
Alternatively, during periods of rising interest rates, mortgage-related
securities are often more susceptible to extension risk (i.e. rising interest
rates could cause property owners to prepay their mortgage loans more slowly
than expected when the security was purchased by the Portfolio which may further
reduce the market value of such security and lengthen the duration of such
security).

The Portfolio may invest in collateralized mortgage obligations ("CMOs") and
real estate mortgage investment conduits ("REMICs"). CMOs are debt obligations
collateralized by a pool of mortgage loans or mortgaged-related securities which
generally are held under an indenture issued by financial institutions or other
mortgage lenders or issued or guaranteed by agencies or instrumentalities of the
U.S. government. REMICs are private entities formed for the purpose of holding a
fixed pool of mortgages secured by an interest in real property. CMOs and REMICs
generally are issued in a number of classes or series with different maturities.
The classes or series are retired in sequence as the underlying mortgages are
repaid. Such securities generally are subject to market risk, prepayment risk
and extension risk like other mortgage-related securities. Certain of these
securities may have variable or floating interest rates and others may be
stripped (securities which provide only the principal or interest feature of the
underlying security). CMOs or REMICs issued or guaranteed by agencies or
instrumentalities of the U.S. government are treated by the Portfolio as U.S.
government securities.

GOVERNMENT-RELATED SECURITIES. Under normal market conditions, the Portfolio may
invest up to 20% of its assets in, among other things, government-related
securities, including privately issued mortgage-related and mortgage-backed
securities not directly guaranteed by instrumentalities of the U.S. government,
privately issued certificates representing stripped U.S. government or
mortgage-related securities and repurchase agreements fully collateralized by
U.S. government securities.

The Portfolio may invest in private mortgage-related securities ("Private
Pass-Throughs") as opposed to mortgage-related securities issued or guaranteed
by GNMA, FNMA, and FHLMC only if such Private Pass-Throughs are rated at the
time of purchase in the two highest grades by a nationally recognized
statistical rating agency ("NRSRO") or in any unrated debt security considered
by the Portfolio's investment adviser to be of comparable quality. CMOs and
REMICs issued by private entities and not directly guaranteed by any government
agency or instrumentality are secured by the underlying collateral of the
private issuer. The Portfolio will invest in such privately issued securities
only if: they are 100% collateralized at the time of issuance by securities
issued or guaranteed by the U.S. government, its agencies or its
instrumentalities and they are rated at the time of purchase in the two highest
grades by a NRSRO. A more complete description of security ratings, is contained
in the appendix to this prospectus.

The Portfolio may invest in the principal only or interest only components of
U.S. government securities. In the last few years, agencies or instrumentalities
of the U.S. government and a number of banks and brokerage firms have separated
("stripped") the principal portions from the coupon portions of U.S. Treasury
bonds and notes and sold them separately in the form of receipts or certificates
representing undivided interests in these instruments (which instruments are
often held by a bank in a custodial or trust account). Such custodial receipts
or certificates of private issuers are not considered by the Fund to be U.S.
government securities. The principal only securities are not entitled to any
periodic payments of interest prior to maturity. Such securities usually trade
at a deep discount from their face or par value and are subject to greater
fluctuations of market value in response to changing

                                       45
<PAGE>   48

interest rates than debt obligations of comparable maturities which make current
distributions of interest. Current federal tax law requires that a holder (such
as the Portfolio) of a principal only security accrue a portion of the discount
at which the security was purchased as income each year even though the
Portfolio received no interest payment in cash on the security during the year.
The Portfolio is required to distribute substantially all of its income each
year and, in order to generate sufficient cash to make distributions of such
income, the Portfolio may have to dispose of securities that it would otherwise
continue to hold, which, in some cases may be disadvantageous to the Fund.

Stripped mortgage-related securities (hereinafter referred to as "stripped
mortgage securities") are derivative multiclass mortgage securities. Stripped
mortgage securities may be issued by agencies or instrumentalities of the U.S.
government, or by private originators of, or investors in, mortgage loans,
including savings and loan associations, mortgage banks, commercial banks,
investment banks and special purpose subsidiaries of the foregoing. Stripped
mortgage securities usually are structured with two classes that receive
different proportions of the interest and principal distributions on a pool of
mortgage assets. A common type of stripped mortgage securities will have one
class receiving some of the interest and most of the principal from the mortgage
assets, while the other class will receive most of the interest and the
remainder of the principal. In the most extreme case, one class will receive all
of the interest (the interest-only or "IO" class), while the other class will
receive all of the principal (the principal-only or "PO" class). The yield to
maturity on an IO class is extremely sensitive to the rate of principal payments
(including prepayments) on the related underlying mortgage assets, and a rapid
rate of principal payments may have a material adverse effect on the securities'
yield to maturity. If the underlying mortgage assets experience greater than
anticipated prepayments of principal, the Portfolio may fail to fully recoup its
initial investment in these securities even if the security is rated the highest
quality by a NRSRO. Holders of PO securities are not entitled to any periodic
payments of interest prior to maturity. Accordingly, such securities usually
trade at a deep discount from their face or par value and are subject to greater
fluctuations of market value in response to changing interest rates than debt
obligations of comparable maturities which make current distributions of
interest. Current federal tax law requires that a holder (such as the Portfolio)
of principal only securities accrue a portion of the discount at which the
security was purchased as income each year even though the holder receives no
interest payment in cash on the certificate during the year. In order to
generate sufficient cash to make distributions of such income, the Portfolio may
have to dispose of securities that it would otherwise continue to hold, which,
in some cases, may be disadvantageous to the Portfolio.

Although the market for stripped securities is increasingly liquid, certain of
such securities may not be readily marketable and will be considered illiquid
for purposes of the Portfolio's limitation on investments in illiquid
securities. The Portfolio will follow established guidelines and standards for
determining whether a particular stripped security is liquid. Generally, such a
security may be deemed liquid if it can be disposed of promptly in the ordinary
course of business at a value reasonably close to that used in the calculation
of the net asset value per share. Stripped mortgage securities, other than
government-issued IO and PO securities backed by fixed-rate mortgages, are
presently considered by the staff of the SEC to be illiquid securities and thus
subject to the Portfolio's limitation on investment in illiquid securities.

INTEREST RATE TRANSACTIONS. The Portfolio may enter into interest rate swaps and
may purchase or sell interest rate caps, floors and collars. The Portfolio
expects to enter into these transactions primarily to preserve a return or
spread on a particular investment or portion of its portfolio. The Portfolio may
also enter into these transactions to protect against any increase in the price
of securities the Portfolio anticipates purchasing at a later date. Interest
rate swaps, caps, floors and collars will be treated as illiquid securities for
the purposes of the Portfolio's investment restriction limiting investment in
illiquid securities. Besides liquidity, such transactions include market risk,
risk of default by the other party to the transaction, risk of imperfect
correlation and manager risk. Such transactions may involve commissions or other
costs. A more complete discussion of interest rate transactions and their risks
is contained in the Statement of Additional Information.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase or sell
U.S. government securities on a "when-issued" or "delayed delivery" basis
("Forward Commitments"). These transactions occur when securities are purchased
or sold by the Portfolio with payment and delivery taking place in the future,
frequently a month or more after such transaction. The price is fixed on the
date of the commitment, and the seller continues to accrue interest on the
securities covered by the Forward Commitment until delivery and payment take
place.

                                       46
<PAGE>   49

At the time of settlement, the market value of the securities may be more or
less than the purchase or sale price. The Portfolio may either settle a Forward
Commitment by taking delivery of the securities or may either resell or
repurchase a Forward Commitment on or before the settlement date in which event
the Portfolio may reinvest the proceeds in another Forward Commitment. These
transactions are subject to market risk as the value or yield of a security at
delivery may be more or less than the purchase price or the yield generally
available on securities when delivery occurs. When engaging in Forward
Commitments, the Portfolio relies on the other party to complete the
transaction, should the other party fail to do so, the Portfolio might lose a
purchase or sale opportunity that could be more advantageous than alternative
opportunities at the time of the failure. The Portfolio maintains a segregated
account (which is marked to market daily) of cash or liquid portfolio securities
with the Portfolio's custodian in an aggregate amount equal to the amount of its
commitment as long as the obligation to purchase or sell continues.

                          GROWTH AND INCOME PORTFOLIO

The investment objective of the Growth and Income Portfolio is to seek long-term
growth of capital and income. There are risks inherent in all investments in
securities; accordingly, there can be no assurance that the Portfolio will
achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing primarily in income-producing
equity securities, including common stocks and convertible securities; although
investments are also made in non-convertible preferred stocks and debt
securities rated "investment grade," which are securities rated within the four
highest grades assigned by Standard & Poor's ("S&P") or by Moody's Investors
Service, Inc. ("Moody's"). A more complete description of security ratings is
contained in the appendix to this prospectus.

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so.

A convertible security is a bond, debenture, note, preferred stock, warrant or
other security that may be converted into or exchanged for a prescribed amount
of common stock or other equity security of the same or a different issuer
within a particular period of time at a specified price or formula. A
convertible security generally entitles the holder to receive interest paid or
accrued on debt or the dividend paid on preferred stock until the convertible
security matures or is redeemed, converted or exchanged. Before conversion,
convertible securities generally have characteristics similar to both debt and
equity securities. The value of convertible securities tends to decline as
interest rates rise and, because of the conversion feature, tends to vary with
fluctuations in the market value of the underlying equity security. Convertible
securities ordinarily provide a stream of income with generally higher yields
than those of common stock of the same or similar issuers. Convertible
securities generally rank senior to common stock in a corporation's capital
structure but are usually subordinated to comparable nonconvertible securities.
Convertible securities generally do not participate directly in any dividend
increases or decreases of the underlying equity security although the market
prices of convertible securities may be affected by any such dividend changes or
other changes in the underlying equity security.

While the Portfolio invests primarily in income-producing equity securities, the
Portfolio may invest in non-convertible adjustable or fixed rate preferred stock
and debt securities. Preferred stock generally has a preference as to dividends
and liquidation over an issuer's common stock but ranks junior to debt
securities in an issuer's capital structure. Unlike interest payments on debt
securities, preferred stock dividends are payable only if declared by the
issuer's board of directors. Preferred stock also may be subject to optional or
mandatory redemption provisions. The Portfolio may invest in debt securities of
various maturities. The Portfolio invests only in debt securities rated
investment grade at the time of investment, and a subsequent reduction in rating
does not require the Portfolio to dispose of a security. Securities rated BBB by
S&P or Baa by Moody's are in the lowest of the four investment grades and are
considered by the rating agencies to be medium grade obligations which possess
speculative characteristics so that changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than in the case of higher rated securities. A more
complete description of security ratings is contained in the appendix to this
prospectus. The market prices of debt securities generally fluctuate inversely
with

                                       47
<PAGE>   50

changes in interest rates so that the value of investments in such securities
can be expected to decrease as interest rates rise and increase as interest
rates fall and such fluctuations generally are larger among securities with
longer durations.

In selecting common stocks for investment, the Portfolio will focus primarily on
the security's potential for capital growth and income. The Portfolio's
investment adviser may focus on larger capitalization companies which it
believes possess characteristics for improved valuation. The Portfolio may
invest in issuers of small-, medium- or large-capitalization companies. The
securities of small- or medium-sized companies may be subject to more abrupt or
erratic market movements than securities of larger, more established companies
or the market averages in general. In addition, such companies typically are
subject to a greater degree of change in earnings and business prospects than
are larger, more established companies. Thus, the Portfolio may be subject to
greater investment risk than that assumed through investment in the equity
securities of larger, more established companies.

The Portfolio may dispose of a security whenever, in the opinion of the
Portfolio's investment adviser, factors indicate it is desirable to do so. Such
factors include change in economic or market factors in general or with respect
to a particular industry, a change in the market trend or other factors
affecting an individual security, changes in the relative market performance or
appreciation possibilities offered by individual securities and other
circumstances bearing on the desirability of a given investment.

The Portfolio may invest up to 15% of its total assets in securities of foreign
issuers. See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                             MONEY MARKET PORTFOLIO

The investment objective of the Money Market Portfolio is to seek protection of
capital and high current income through investments in money market instruments.
There are risks inherent in all investments in securities; accordingly there can
be no assurance that the Portfolio will achieve its investment objective.

The Portfolio seeks to maintain a constant net asset value of $1.00 per share by
investing in a diversified portfolio of money market instruments maturing within
one year with a dollar-weighted average maturity of 90 days or less. The
Portfolio seeks high current income from these short-term investments to the
extent consistent with protection of capital.

The investment policies, the percentage limitations, and the kinds of securities
in which the Portfolio can invest may be changed by the Portfolio's Board of
Trustees, unless expressly governed by those limitations stated under
"Investment Restrictions" in the Trust's Statement of Additional Information
which can be changed only by action of the shareholders of the Portfolio. It is
not the intention of the Portfolio's Trustees, however, to change these policies
without prior notice to shareholders.

There are risks inherent in all investments in securities, accordingly there can
be no assurance that the Portfolio will achieve its investment objective or that
the Portfolio will be able at all times to preserve the net asset value per
share at $1.00 per share. The daily dividend rate paid by the Portfolio is
expected to fluctuate with changes in prevailing market interest rates. The
Portfolio uses the amortized cost method for valuing portfolio securities
purchased at a discount.

The Portfolio may invest in money market instruments of the following types, all
of which will be U.S. dollar obligations:

OBLIGATIONS OF THE U.S. GOVERNMENT, ITS AGENCIES OR ITS INSTRUMENTALITIES. The
Portfolio may invest in obligations issued or guaranteed as to principal and
interest by the U.S. government, its agencies or its instrumentalities which are
supported by any of the following: (a) the full faith and credit of the U.S.
government, (b) the right of the issuer to borrow an amount limited to a
specific line of credit from the U.S. government, (c) discretionary authority of
the U.S. government to purchase obligations of its agencies or instrumentalities
or (d) the credit of the instrumentality. Such agencies or instrumentalities
include, but are not limited to, the Federal National Mortgage Association, the
Government National Mortgage Association, Federal Land Banks, and the Farmer's
Home Administration.

                                       48
<PAGE>   51

BANK OBLIGATIONS. The Portfolio may invest in negotiable time deposits,
certificates of deposit and bankers' acceptances which are obligations of
domestic banks having total assets in excess of $1 billion as of the date of
their most recently published financial statements. The Portfolio is also
authorized to invest up to 5% of its total assets in certificates of deposit
issued by domestic banks having total assets of less than $1 billion, provided
that the principal amount of the certificate of deposit acquired by the
Portfolio is insured in full by the Federal Deposit Insurance Corporation.

COMMERCIAL PAPER. The Portfolio may invest in short-term commercial paper
obligations of companies which at the time of investment are (a) rated in one of
the two highest categories by at least two nationally recognized statistical
organizations (or one rating organization if the obligation was rated by only
one such organization) or (b) if unrated, are of comparable quality as
determined in accordance with procedures established by the Portfolio's Board of
Trustees. Commercial paper consists of short-term (usually from 1 to 270 days)
unsecured promissory notes issued by corporations in order to finance their
current operations. The Portfolio's current policy is to limit investments in
commercial paper to obligations rated in the highest rating category. A more
complete description of security ratings is in the appendix to this prospectus.

REPURCHASE AGREEMENTS. The Portfolio may enter into repurchase agreements with
banks and broker-dealers which involve certain risks in the event of a default
by the other party. See "Investment Practices -- Repurchase Agreements" below
and in the Statement of Additional Information.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                                 MORGAN STANLEY

                        REAL ESTATE SECURITIES PORTFOLIO

The primary investment objective of the Morgan Stanley Real Estate Securities
Portfolio is to seek long-term growth of capital. Current income is a secondary
investment objective. There are risks inherent in all investments in securities;
accordingly, there can be no assurance that the Portfolio will achieve its
investment objectives.

The Portfolio's investment adviser seeks to achieve the investment objectives by
investing primarily in a portfolio of securities of companies operating in the
real estate industry. A company operating in the real estate industry is one
that derives at least 50% of its assets (marked-to-market), gross income or net
profits from the ownership, construction, management or sale of residential,
commercial or industrial real estate. Real estate industry companies include,
among others: equity real estate investment trusts, which pool investors' funds
for investment primarily in commercial real estate properties; mortgage real
estate investment trusts, which invest pooled funds in real estate related
loans; brokers or real estate developers; and companies with substantial real
estate holdings, such as paper and lumber products and hotel and entertainment
companies. Because of the Portfolio's policy of concentrating its investments in
real estate securities, the Portfolio may be more susceptible to economic,
political or regulatory occurrences affecting the real estate industry than a
portfolio without such a policy.

Under normal market conditions, the Portfolio invests at least 65% of its total
assets in securities of companies operating in the real estate industry,
including equity securities of REITs and other securities of real estate
operating companies. The Portfolio's investment adviser diversifies its
investments as to issuers, property types and regions. The investment adviser's
approach emphasizes a bottom-up stock selection with a top-down asset allocation
overlay. Besides equity securities of REITs, the Portfolio also invests in
equity securities, including common stocks and convertible securities, or non-
convertible preferred stocks and investment-grade debt securities of real estate
industry companies. REITs pool investors' funds for investment primarily in
income producing real estate or real estate related loans or interests. REITs
can generally be classified as equity REITs, mortgage REITs or a combination of
both. Equity REITs, which invest the majority of their assets directly in real
property, derive their income from rents. Equity REITs can also realize capital
gains by selling properties that have appreciated in value. Mortgage REITs,
which invest the majority of their assets in real estate mortgagees, derive
their income primarily from interest payments. REITs are not taxed on income
distributed to shareholders provided such REITs comply with several requirements
of the Internal Revenue Code of 1986, as amended (the "Code").

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the

                                       49

profits of the corporation, if any, without preference over any other class of
securities, including such entity's debt securities, preferred stock and other
senior equity securities. Common stock usually carries with it the right to vote
and frequently an exclusive right to do so.

A convertible security is a bond, debenture, note, preferred stock, warrant or
other security that may be converted into or exchanged for a prescribed amount
of common stock or other equity security of the same or a different issuer
within a particular period of time at a specified price or formula. A
convertible security generally entitles the holder to receive interest paid or
accrued on debt securities or the dividend paid on preferred stock until the
convertible security matures or is redeemed, converted or exchanged. Before
conversion, convertible securities generally have characteristics similar to
both debt and equity securities. The value of convertible securities tends to
decline as interest rates rise and, because of the conversion feature, tends to
vary with fluctuations in the market value of the underlying equity security.
Convertible securities ordinarily provide a stream of income with generally
higher yields than those of common stock of the same or similar issuers.
Convertible securities generally rank senior to common stock in a corporation's
capital structure but are usually subordinated to comparable nonconvertible
securities. Convertible securities generally do not participate directly in any
dividend increases or decreases of the underlying equity security although the
market prices of convertible securities may be affected by any such dividend
changes or other changes in the underlying equity security.

Preferred stock generally has a preference as to dividends and liquidation over
an issuer's common stock but ranks junior to debt securities in an issuer's
capital structure. Unlike interest payments on debt securities, preferred stock
dividends are payable only if declared by an issuer's board of directors.
Preferred stock may be subject to optional or mandatory redemption provisions.
The ability of common stocks and preferred stocks to generate income is
dependent on the earnings and continuing declaration of dividends by the issuers
of such securities.

Debt securities of a corporation or other entity generally entitle the holder to
receive interest, at a fixed, variable or floating interest rate, during the
term of the security and repayment of principal at maturity or redemption. The
Portfolio invests in investment-grade debt securities (securities rated at the
time of investment BBB or higher by Standard & Poor's ("S&P") or rated Baa or
higher by Moody's Investors Service, Inc. ("Moody's") or comparably rated by
another nationally recognized statistical rating organization ("NRSRO") or
unrated securities considered by the Portfolio's investment adviser to be of
comparable quality). Credit quality at the time of purchase determines which
securities may be acquired, and a subsequent reduction in ratings does not
require the Portfolio to dispose of a security. Securities rated BBB by S&P or
Baa by Moody's are considered to be medium-grade obligations which possess
speculative characteristics so that changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than in the case of higher-rated securities. The ratings
assigned by the ratings agencies represent their opinions of the quality of the
debt securities they undertake to rate, but not the market value risk of such
securities. It should be emphasized that ratings are general and are not
absolute standards of quality. A more complete description of security ratings
is contained in the appendix to this prospectus.

Under normal market conditions, the Portfolio may invest up to 35% of its total
assets in securities of companies outside the real estate industry.

The Portfolio may invest up to 25% of its total assets in securities issued by
foreign issuers, some or all of which also may be in the real estate industry.
See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

RISK FACTORS OF INVESTING IN REAL ESTATE SECURITIES. The values and return on
securities of companies in the real estate industry may or may not fluctuate in
tandem with the overall securities' markets. Although the Portfolio does not
invest directly in real estate, an investment in the Portfolio generally will be
subject to the risks associated with investments in real estate because of its
policy of concentrating in the securities of companies operating in the real
estate industry. These risks include, among others: declines in the value of
real estate; defaults by borrowers or tenants; risks related to general and
local economic conditions; overbuilding and increased competition; increases in

                                       50
<PAGE>   53

property taxes, capital expenditures or operating expenses; changes in zoning
laws; casualty or condemnation losses; variations in rental income; changes in
neighborhood values; the appeal of properties to tenants; changes in interest
rates; and political or regulatory occurrences affecting the real estate
industry. The value of securities of companies which service the real estate
industry also will be affected by such risks. If the Portfolio has rental income
or income from the disposition of real property acquired as a result of a
default on securities the Portfolio may own, the receipt of such income may
adversely affect the Portfolio's ability to retain its tax status as a regulated
investment company.

Equity REITs may be affected by changes in the value of the underlying property
owned by the trusts, while mortgage REITs may be affected by changes in interest
rates and the quality of credit extended. Equity and mortgage REITs are
dependent upon management skill, may not be diversified (which may increase the
volatility of the REIT's value) and are subject to the risks of financing
projects. REITs are subject to heavy cash flow dependency, defaults by
borrowers, self-liquidation and the possibility of failing to qualify for
tax-free pass-through of income under the Code and to maintain exemption from
the Investment Company Act of 1940, as amended (the "1940 Act"). REITs are not
taxed on income distributed to shareholders provided they comply with several
requirements of the Code. Mortgage REITs, like debt securities, tend to decline
in value as interest rates rise. Mortgage REITs are often more susceptible than
traditional debt securities to further price declines in periods of rising
interest rates because of extension risks (i.e. rising interest rates could
cause property owners to prepay their mortgages more slowly than expected when
the security was purchased by the Portfolio which may further reduce the market
value of such security and lengthen the duration of the security). In addition,
mortgage REITs tend to benefit less than traditional debt securities when
interest rates decline because underlying mortgages often get prepaid faster
than expected in periods of declining interest rates. In addition, the Portfolio
indirectly will bear its proportionate share of any expenses paid by the REITs
in which it invests.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase and sell
debt securities on a "when-issued" or "delayed delivery" basis ("Forward
Commitments"). These transactions occur when securities are purchased or sold by
the Portfolio with payment and delivery taking place in the future, frequently a
month or more after such transaction. The price is fixed on the date of the
commitment, and the seller continues to accrue interest on the securities
covered by the Forward Commitment until delivery and payment take place. At the
time of settlement, the market value of the securities may be more or less than
the purchase or sale price. The Portfolio may either settle a Forward Commitment
by taking delivery of the securities or may either resell or repurchase a
Forward Commitment on or before the settlement date in which event the Portfolio
may reinvest the proceeds in another Forward Commitment. These transactions are
subject to market risk as the value or yield of a security at delivery may be
more or less than the purchase price or the yield generally available on
securities when delivery occurs. When engaging in Forward Commitments, the
Portfolio relies on the other party to complete the transaction, should the
other party fail to do so, the Portfolio might lose a purchase or sale
opportunity that could be more advantageous than alternative opportunities at
the time of the failure. The Portfolio maintains a segregated account (which is
marked to market daily) of cash or liquid portfolio securities with the
Portfolio's custodian in an aggregate amount equal to the amount of its
commitment as long as the obligation to purchase or sell continues.

                           STRATEGIC STOCK PORTFOLIO

The investment objective of the Strategic Stock Portfolio is to seek an above
average total return through a combination of potential capital appreciation and
dividend income, consistent with the preservation of invested capital. There are
risks inherent in all investments in securities; accordingly, there can be no
assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing in a portfolio of high dividend
yielding equity securities of companies included in the DJIA or in the MSCI USA
Index. The DJIA was first published in The Wall Street Journal in 1896.
Initially consisting of just 12 stocks, the DJIA expanded to 20 stocks in 1916
and to its present size of 30 stocks on October 1, 1928. The MSCI USA Index
consists of approximately 370 large domestic companies in the United States and
has existed since January 1, 1970.

The Portfolio's investment adviser selects investment securities for the
Portfolio based upon the Portfolio's

                                       51
<PAGE>   54

strategic selection policies (the "Strategic Selection Policies") as follows:

The ten highest dividend yielding securities in the DJIA are identified for
investment. In addition, all companies having securities in the MSCI USA Index
are reviewed by the Portfolio's investment adviser. Securities of companies in
the financial or utility sectors and companies having securities included in the
DJIA are excluded. The remaining pool of MSCI USA Index securities is further
evaluated and securities of companies that do not have positive one- and
three-year sales and earnings growth rates and two years of positive dividend
growth are excluded. The Portfolio's investment adviser also excludes MSCI USA
Index securities that are in the bottom 25% of all MSCI USA Index securities
measured in terms of total annual trading volume. MSCI USA Index securities of
the remaining companies are ranked by dividend yield, and the ten
highest-yielding such MSCI USA Index securities are identified for investment.
In the event that this process results in less than 10 remaining MSCI USA Index
securities, those companies with the most favorable one- and three-year sales
and earnings performance and two-year dividend performance as determined by the
Portfolio's investment adviser are added back until the number of MSCI USA Index
securities equals 10. Dividend yield for purposes of applying the foregoing
investment policies is calculated for each security by annualizing the last
quarterly or semi-annual ordinary dividend declared on the security and dividing
the result by the security's closing sale price on the applicable date. This
yield is historical and there can be no assurance that any dividends will be
declared or paid in the future.

At the commencement of the Portfolio's investment operations, the 20 securities
so identified at that time represented the Portfolio's initial investments.
Approximately monthly, the Portfolio's investment adviser employs the same
Strategic Selection Policies to identify a new list of 20 strategic securities.
Based on a rolling 12-month schedule, the investment adviser reviews and adjusts
the oldest one-twelfth portion of the Portfolio's assets so as to invest that
portion of the Portfolio's assets approximately equally in the new list of 20
strategic securities. For a more detailed discussion of the Portfolio's
investment policies, including the frequency of security re-evaluations and the
portion of the Portfolio's assets that the Portfolio's investment adviser
presently expects to re-evaluate at the end of each period, see the Statement of
Additional Information.

The Portfolio's investment adviser generally seeks to allocate cash available
for investment due to the sale of new shares of the Portfolio and the receipt of
dividends and interest income from Portfolio investments approximately
proportionately among its current list of strategic securities in the Portfolio.
To the extent that the Portfolio is required to dispose of securities in order
to satisfy redemption requests, make distributions, pay expenses or otherwise
raise cash for operational purposes, the Portfolio's investment adviser
generally intends to sell approximately proportionate amounts of securities from
all securities in the Portfolio.

Application of the foregoing Strategic Selection Policies is subject to and
limited by certain of the Portfolio's other investment policies and
restrictions, including restrictions and limitations which must be met in order
for the Portfolio to qualify for U.S. federal income tax purposes as a
"regulated investment company" under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"), or in order to comply with requirements of the
1940 Act. The Portfolio is subject to investment diversification requirements
that generally provide that the Portfolio may not, with respect to 75% of its
assets, invest more than 5% of its assets in the securities of any one issuer or
purchase more than 10% of the outstanding voting securities of any one issuer.
Further, the Portfolio generally may not invest more than 25% of the value of
its total assets in securities of issuers in any particular industry. The
Portfolio's satisfaction of these requirements will take precedent over the
Strategic Selection Policies. In addition, the Portfolio's investment adviser
will try to avoid transacting in odd-lots of securities in order to minimize
transaction costs. These limitations may, at times, cause the composition of the
Portfolio's investment portfolio to differ significantly from that which would
have resulted had the Strategic Selection Policies been fully implemented. In
selecting securities for investment or disposition at times that the Portfolio's
investment policies and restrictions do not permit full implementation of the
Strategic Selection Policies, the Portfolio's investment adviser will have sole
discretion to select securities for purchase or sale and generally will make
such selections in a manner that is consistent with the Portfolio's investment
objective and in a manner that it believes is consistent with the investment
rationale that is the basis for the Strategic Selection Policies.

The Portfolio will continue to hold securities, even though such securities may
not be included in the most recent list of strategic securities determined for
the review and adjustment of a portion of the Portfolio's assets. In addition,
although each new list

                                       52
<PAGE>   55

of strategic securities will include only 20 securities, because only a portion
of the Portfolio's assets may be reviewed and adjusted at any given time, the
Portfolio's investment adviser expects that the number of securities held by the
Portfolio may over time increase and that the Portfolio may at times hold forty
or more different securities.

The Portfolio may invest up to 5% of its total assets in options on equity
securities indices, futures contracts on such indices and options on such
futures contracts for both hedging purposes and in an attempt to enhance gain.
The Portfolio also may invest up to 5% of its total assets in securities of
other registered investment companies that seek to provide investment results
that generally correspond to the performance of securities included in one or
more broad market indices. Investment in securities of other investment
companies will subject the Portfolio to additional and potentially duplicative
costs and expenses, including investment management fees charged by such
registered investment companies. Pending investment and for temporary defensive
purposes the Portfolio may invest without limit in short-term, high quality
fixed income securities and in money-market instruments.

The DJIA is the property of Dow Jones & Company, Inc. Dow Jones & Company, Inc.
has not granted to the Portfolio a license to use the DJIA. Dow Jones & Company,
Inc. has not participated in any way in the creation of the Portfolio or in the
selection of the stocks included in such Portfolio and has not approved any
information herein relating thereto. Shares of the Portfolio are not designed so
that their prices will parallel or correlate with any movements in the DJIA, and
it is expected that their prices will not parallel or correlate with such
movements.

The MSCI USA Index is the property of Morgan Stanley Dean Witter & Co. ("Morgan
Stanley"). Morgan Stanley makes no representation or warranty, express or
implied, to the owners of shares of the Portfolio or any member of the public
regarding the advisability of investing in investment portfolios generally or in
the Portfolio particularly or the ability of the MSCI USA Index to track general
stock market performance. Morgan Stanley is the licensor of certain trademarks,
service marks and trade names of Morgan Stanley and of the MSCI USA Index which
is determined, composed and calculated by Morgan Stanley without regard to this
Portfolio. Morgan Stanley has no obligation to take the needs of this Portfolio
or the owners of this Portfolio into consideration in determining, composing or
calculating the MSCI USA Index. Morgan Stanley is not responsible for and has
not participated in the determination of the timing of, prices at, or quantities

RISK FACTORS. There is no guarantee that the investment objective of the
Portfolio will be achieved because it is subject to the continuing ability of
the respective issuers of equity securities in which the Portfolio invests to
declare and pay dividends and because the market value of such equity securities
can be affected by a variety of factors. Common stocks may be especially
susceptible to general stock market movements and to volatile increases and
decreases of value as market confidence in and perceptions of the issuers
change. There can be no assurance that the value of the underlying securities
will increase or that the issuers of the securities will pay dividends on
outstanding securities. The declaration of dividends by any issuer depends upon
several factors including the financial condition of the issuer and general
economic conditions. Risks associated with an investment in the Portfolio
include the possible

                                       53
<PAGE>   56

deterioration of either the financial condition of the issuers or the general
condition of the stock market, and general price volatility. The relatively high
dividend yield of certain securities that the Portfolio will acquire may reflect
the market's assessment of the risk that the company may reduce or eliminate the
dividend in the current period or in the future, or otherwise reflect the
market's unfavorable assessment of the company's performance outlook. The
Portfolio's investment adviser generally will not take these considerations into
account in implementing the Strategic Selection Policies and, accordingly, the
Portfolio may at times acquire securities of companies that the market and the
Portfolio's investment adviser believe are more susceptible to financial
difficulty and corresponding adverse market performance than are other companies
with securities included in the DJIA or in the MSCI USA Index.

In addition, investors should be aware that the Portfolio is not "actively
managed." Except to raise cash for operational purposes, the Portfolio
ordinarily will not sell securities or re-evaluate its investments except as
periodically determined by the Portfolio's investment adviser. In addition, only
a portion of the Portfolio's assets may be reviewed and adjusted for any given
period. As a result, although the Portfolio may (but need not) dispose of a
security in certain events such as the issuer having defaulted on the payment on
any of its outstanding obligations or the price of a security having declined to
such an extent or other factors existing so that in the opinion of the
Portfolio's investment adviser the retention of such security would be
detrimental to the Portfolio, the adverse financial condition of a company will
not result in its elimination from the Portfolio prior to scheduled review and
adjustment except under extraordinary circumstances. Similarly, securities held
in the Portfolio ordinarily will not be sold by the Portfolio for the purpose of
taking advantage of market fluctuations or changes in anticipated rates of
appreciation.

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                              INVESTMENT PRACTICES

                             REPURCHASE AGREEMENTS

Each Portfolio may enter into repurchase agreements with banks or broker-dealers
in order to earn a return on temporarily available cash. A repurchase agreement
is a short-term investment in which the purchaser (i.e., the Portfolio) acquires
ownership of a debt security and the seller agrees to repurchase the obligation
at a future time and set price, thereby determining the yield during the holding
period. Repurchase agreements involve certain risks in the event of default by
the other party. Each Portfolio may enter into repurchase agreements with banks
or broker-dealers deemed to be creditworthy by the Portfolio's investment
adviser under guidelines approved by the Portfolio's Board of Trustees. No
Portfolio will invest in repurchase agreements maturing in more than seven days
if any such investment, together with any other illiquid securities held by such
Portfolio, would exceed the Portfolio's limitation on illiquid securities
described below. In the event of the bankruptcy or other default of a seller of
a repurchase agreement, a Portfolio could experience both delays in liquidating
the underlying securities and losses including: (a) possible decline in the
value of the underlying security during the period while the Portfolio seeks to
enforce its rights thereto; (b) possible lack of access to income on the
underlying security during this period; and (c) expenses of enforcing its
rights.

For the purpose of investing in repurchase agreements, a Portfolio's investment
adviser may aggregate the cash that certain funds or portfolios advised or
subadvised by the investment adviser or certain of its affiliates would
otherwise invest separately into a joint account. The cash in the joint account
is then invested in repurchase agreements and the funds or portfolios that
contributed to the joint account share pro rata in the net revenue generated.
The investment adviser believes that the joint account produces efficiencies and
economies of scale that may contribute to reduced transaction costs, higher
returns, higher quality investments and greater diversity of investments for the
participating Portfolio than would be available to the Portfolio investing
separately. The manner in which the joint account is managed is subject to
conditions set forth in an exemptive order from the SEC authorizing this
practice, which conditions are designed to ensure the fair

                                       54
<PAGE>   57

administration of the joint account and to protect the amounts in that account.

Repurchase agreements are fully collateralized by the underlying debt securities
and are considered to be loans under the 1940 Act. A Portfolio pays for such
securities only upon physical delivery or evidence of book entry transfer to the
account of a custodian or bank acting as agent. The seller under a repurchase
agreement will be required to maintain the value of the underlying securities
marked-to-market daily at not less than the repurchase price. The underlying
securities (normally securities of the U.S. government, or its agencies and its
instrumentalities) may have maturity dates exceeding one year. A Portfolio does
not bear the risk of a decline in value of the underlying security unless the
seller defaults under its repurchase obligation.

                               FOREIGN SECURITIES

Each of the Portfolios listed below may invest in securities issued by foreign
issuers up to the following limits:


<TABLE>
<S>                         <C>
Asset Allocation Portfolio  Up to 25% of total assets

Securities Portfolio        Up to 25% of total assets
 ..........................................................
</TABLE>


Such securities may be denominated in U.S. dollars or in currencies other than
U.S. dollars. Investments in foreign securities present certain risks not
ordinarily associated with investments in securities of U.S. issuers. These
risks include fluctuations in foreign currency exchange rates, political,
economic or legal developments (including war or other instability,
expropriation of assets, nationalization and confiscatory taxation), imposition
of foreign exchange limitations (including currency blockage), withholding taxes
on dividend or interest payments or capital transactions or other restrictions,
higher transaction costs (including higher brokerage, custodial and settlement
costs and currency translation costs) and possible difficulty in enforcing
contractual obligations or taking judicial action. Also, foreign securities may
not be as liquid and may be more volatile than comparable domestic securities.

In addition, there often is less publicly available information about many
foreign issuers, and issuers of foreign securities are subject to different,
often less comprehensive, auditing, accounting, financial reporting and
disclosure requirements than domestic issuers. There is generally less
government regulation of stock exchanges, brokers and listed companies abroad
than in the U.S., and, with respect to certain foreign countries, there is a
possibility of expropriation or confiscatory taxation, or diplomatic
developments which could affect investment in those countries. Because there is
usually less supervision and governmental regulation of exchanges, brokers and
dealers than there is in the U.S., a Portfolio may experience settlement
difficulties or delays not usually encountered in the U.S.

Delays in making trades in foreign securities relating to volume constraints,
limitations or restrictions, clearance or settlement procedures, or otherwise
could impact yields and result in temporary periods when assets are not fully
invested or attractive investment opportunities are foregone.

A Portfolio's investments in securities of developing or emerging markets are
subject to greater risks than a Portfolio's investments in securities of
developed countries since emerging markets tend to have economic structures that
are less diverse and mature and political systems that are less stable than
developed countries.

Each of these Portfolios may purchase foreign securities in the form of American
Depository Receipts, European Depositary Receipts or other securities
representing underlying shares of foreign companies. The risks of foreign
investments should be considered carefully by an investor in a Portfolio that
invests in foreign securities.

                         FOREIGN CURRENCY TRANSACTIONS

Each Portfolio's securities that are denominated or quoted in currencies other
than the U.S. dollar will be affected by changes in foreign currency exchange
rates (and exchange control regulations) which affects the value of the
securities in the Portfolio and the income or dividends and appreciation or
depreciation of its investments. Changes in foreign currency exchange ratios
relative to the U.S. dollar will affect the U.S. dollar value of the Portfolio's
assets

                                       55
<PAGE>   58

denominated in that currency and the Portfolio's yield on such assets. In
addition, the Portfolio will incur costs in connection with conversions between
various currencies. A Portfolio's foreign currency exchange transactions
generally will be conducted on a spot basis (that is, cash basis) at the spot
rate for purchasing or selling currency prevailing in the foreign currency
exchange market. A Portfolio purchases and sells foreign currency on a spot
basis in connection with the settlement of transactions in securities traded in
such foreign currency. The Portfolios do not purchase and sell foreign
currencies as an investment.

A Portfolio also may enter into contracts with banks or other foreign currency
brokers and dealers to purchase or sell foreign currencies at a future date
("forward contracts") and purchase and sell foreign currency futures contracts
to hedge against changes in foreign currency exchange rates. A foreign currency
forward contract is a negotiated agreement between the contracting parties to
exchange a specified amount of currency at a specified future time at a
specified rate. The rate can be higher or lower than the spot rate between the
currencies that are the subject of the contract.

A Portfolio may attempt to hedge against changes in the value of the U.S. dollar
in relation to a foreign currency by entering into a forward contract for the
purchase or sale of the amount of foreign currency invested or to be invested,
or by buying or selling a foreign currency futures contract for such amount.
Futures contracts are described below under the heading "Investment
Practices -- Using Options, Futures Contracts and Options in Futures Contracts."
Such hedging strategies may be employed before a Portfolio purchases a foreign
security traded in the hedged currency which a Portfolio anticipates acquiring
or between the date the foreign security is purchased or sold and the date on
which payment therefore is made or received. Hedging against a change in the
value of a foreign currency in the foregoing manner does not eliminate
fluctuations in the price of portfolio securities or prevent losses if the
prices of such securities decline. Furthermore, such hedging transactions reduce
or preclude the opportunity for gain if the value of the hedged currency should
move in the direction opposite to the hedged position. Unanticipated changes in
currency prices may result in poorer overall performance for the Portfolio than
if it had not entered into such contracts.

The Portfolio's custodian will place cash or liquid securities in a segregated
account having a value equal to the aggregate amount of the Portfolio's
commitments under forward contracts. If the value of the securities placed in
the segregated account declines, additional cash or securities are placed in the
account on a daily basis so that the value of the account equals the amount of
the Portfolio's commitments with respect to such contracts. As an alternative to
maintaining all or part of the segregated account, the Portfolio may purchase a
call option permitting the Portfolio to purchase the amount of foreign currency
by a forward sale contract at a price no higher than the forward contract price
or the Portfolio may purchase a put option permitting the Portfolio to sell the
amount of foreign currency subject to a forward purchase contract at a price as
high or higher than the forward contract price.

                              ILLIQUID SECURITIES

Each of the Portfolios listed below may invest in illiquid securities and
certain restricted securities up to the following limits:

Such securities may be difficult or impossible to sell at the time and the price
that the Portfolio would like. Thus, the Portfolio may have to sell such
securities at a lower price, sell other securities instead to obtain cash or
forego other investment opportunities.

       USING OPTIONS, FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

Each Portfolio (excluding the Domestic Income Portfolio and the Money Market
Portfolio) may use options, futures contracts or options on futures contracts in
several different ways, depending upon the status of a Portfolio's portfolio
securities and the

                                       56
<PAGE>   59

investment adviser's expectations concerning the securities or currency markets.

In times of stable or rising securities' prices, the Portfolios generally seek
to be fully invested. Even when the Portfolios are fully invested, however,
prudent management requires that at least a small portion of assets be available
as cash to honor redemption requests and for other short-term needs. The
Portfolios may also have cash on hand that has not yet been invested. The
portion of a Portfolio's assets that is invested in cash or cash equivalents
does not fluctuate with overall market prices, so that, in times of rising
market prices, the Portfolio may underperform the market in proportion to the
amount of cash or cash equivalents in the Portfolio. By purchasing stock or bond
index futures contracts, however, the Portfolios can compensate for the cash
portion of its assets and may obtain performance equivalent to investing all of
its assets in securities.

If the Portfolios' investment adviser forecasts a market decline, the Portfolios
may seek to reduce its exposure to the securities markets by increasing its cash
position. By selling stock or bond index futures contracts instead of Portfolio
securities, a similar result can be achieved to the extent that the performance
of the futures contracts correlates to the performance of the Portfolios'
investments. Sales of futures contracts frequently may be accomplished more
rapidly and at less cost than the actual sale of securities. Once the desired
hedged position has been effected, the Portfolios could then liquidate
securities in a more deliberate manner, reducing its futures position
simultaneously to maintain the desired balance, or it could maintain the hedged
position.

As an alternative to futures contracts, the Portfolios can engage in options (or
stock or bond index options or stock or bond index futures options) to manage
the Portfolios' risk in advancing or declining markets. For example, the value
of a put option generally increases as the underlying security declines below a
specified level, value is protected against a market decline to the degree the
performance of the put correlates with the performance of the Portfolios'
investment portfolio. If the market remains stable or advances, the Portfolios
can refrain from exercising the put and the Portfolios will participate in the
advance, having incurred only the premium cost for the put.

The Portfolios are authorized to purchase and sell listed and over-the-counter
options ("OTC Options"). OTC Options are subject to certain additional risks
including default by the other party to the transaction and the liquidity of the
transactions.

In addition to futures and options on securities, the Portfolios may engage in
foreign currency futures and options. The Portfolios may use currency options to
increase its gross income or to protect it against declines in the U.S. dollar
value of foreign currency denominated securities and against increases in the
U.S. dollar cost of such securities to be acquired. As in the case of other
kinds of options, however, the selling of an option on a foreign currency
constitutes only a partial hedge, up to the amount of the premium received, and
the Portfolios could be required to cover its position by purchasing or selling
foreign currencies at disadvantageous exchange rates, thereby incurring losses.
The purchase of an option on a foreign currency may constitute an effective
hedge against fluctuations in exchange rates although, in the event of rate
movements adverse to a Portfolio's position, the Portfolio may forfeit the
entire amount of the premium plus related transaction costs. Options on foreign
currencies in which the Portfolios invest are traded on U.S. and foreign
exchanges or over-the-counter.

In certain cases, the options and futures markets provide investment or risk
management opportunities that are not available from direct investments in
securities. In addition, some strategies can be performed with greater ease and
at lower cost by utilizing the options and futures markets rather than
purchasing or selling portfolio securities or currencies. However, such
transactions involve risks different from the direct investment in underlying
securities such as imperfect correlation between the value of the instruments
and the underlying assets, risks of default by the other party to certain
transactions, risks that the transactions may incur losses that partially or
completely offset gains in portfolio positions, risks that the transactions may
not be liquid and manager risk. In addition, such transactions may involve
commissions and other costs, which may increase a Portfolio's expenses and
reduce its return. A more complete discussion of options, futures contracts and
related options and their risks is contained in the Statement of Additional
Information.

                  OTHER INVESTMENT PRACTICES AND RISK FACTORS

Although the Portfolios do not intend to engage in substantial short-term
trading, each may sell securities without regard to the length of time they have

                                       57
<PAGE>   60

been held in order to take advantage of new investment opportunities or when the
Portfolio's management believes the securities potential relative to the
respective Portfolio's investment objective has lessened or otherwise. Each
Portfolio's turnover rate is shown under the heading "Financial Highlights." The
portfolio turnover rate for each Portfolio may be expected to vary from year to
year. A high portfolio turnover rate (100% or more) increases the Portfolio's
transaction costs, including brokerage commissions or dealer costs, and may
result in the realization of more short-term capital gains than if the Portfolio
had lower portfolio turnover. The turnover rate will not be a limiting factor,
however, if the Portfolio's investment adviser considers portfolio changes
appropriate.

Further information about these types of investments and other investment
practices that may be used by the Portfolios is contained in the Statement of
Additional Information which can be obtained by investors free of charge as
described on the back cover of this prospectus.

TEMPORARY DEFENSIVE STRATEGY. When market conditions dictate a more "defensive"
investment strategy, each Portfolio may invest on a temporary basis a portion or
all of its assets in securities issued or guaranteed by the U.S. government, its
agencies or instrumentalities, prime commercial paper, certificates of deposit,
bankers' acceptances and other obligations of domestic banks having total assets
of at least $500 million, and repurchase agreements. With respect to the Global
Equity Portfolio, the temporary investments may include comparable securities of
foreign governments, their agencies or instrumentalities; however, during times
of international political or economic uncertainty, all or a portion of the
Portfolio's assets may be in U.S. issuers and denominated in U.S. dollars.
Except with respect to the Money Market Portfolio, the effect of taking a
defensive position may be that such Portfolio does not achieve its investment
objective(s).

                               PURCHASE OF SHARES

The Trust is offering its shares only to Accounts of various insurance companies
to fund the benefits of variable annuity or variable life insurance contracts.
The Trust does not foresee any disadvantage to holders of Contracts arising out
of the fact that the interests of the holders may differ from the interests of
holders of life insurance policies and that holders of one insurance policy may
differ from holders of other insurance policies. Nevertheless, the Trust's
Trustees intend to monitor events in order to identify any material
irreconcilable conflicts which may possibly arise and to determine what action,
if any, should be taken. The Contracts are described in the separate
prospectuses issued by participating insurance companies and accompanying this
Trust's prospectus.

The Trust continuously offers shares in each of the Portfolios to the Accounts
at prices equal to the respective per share net asset value of the Portfolio.
The Distributor, located at 1 Parkview Plaza, PO Box 5555, Oakbrook Terrace,
Illinois 60181-5555, acts as the distributor of the shares. Each of the Trust
and the Distributor reserves the right to refuse any order for the purchase of
shares. Net asset value is determined in the manner set forth below under
"Determination of Net Asset Value."

                        DETERMINATION OF NET ASSET VALUE

Net asset value per share is computed for each Portfolio as of the close of
trading (currently 4:00 p.m., New York time) each day the New York Stock
Exchange is open. See the accompanying prospectus for the policies for
information regarding holidays observed by the insurance company. Net asset
value of each Portfolio is determined by adding the total market value of all
portfolio securities held by the Portfolio, cash and other assets, including
accrued interest. All liabilities, including accrued expenses, of the Portfolio
are subtracted. The resulting amount is divided by the total number of
outstanding shares of the Portfolio to arrive at the net asset value of each
share. See "Determination of Net Asset Value" in the Statement of Additional
Information for further information.

Securities listed or traded on a national securities exchange are valued at the
last sale price. Unlisted securities and listed securities for which the last
sales price is not available are valued at the mean between the last reported
bid and asked prices. U.S. government and agency obligations are valued at the
mean between the last reported bid and asked prices. Listed options are valued
at the last reported sale price on the exchange on which such option is traded
or, if no sales are reported, at the mean between the last reported bid and
asked prices. Private placement securities are valued at the last reported bid
price. Securities for which market quotations are not readily available and
other assets are valued at a fair value in good faith by the Adviser in
accordance with procedures established by the Portfolio's Board of Trustees.
Short-term investments for all Portfolios other than the Money Market Portfolio
are valued as described in the notes to financial statements in the Statement of
Additional Information.

                                       62
<PAGE>   65

The Money Market Portfolio's assets are valued on the basis of amortized cost,
which involves valuing a portfolio security at its cost, assuming a constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the security. While this
method provides certainty in valuation, it may result in periods in which value
as determined by amortized cost is higher or lower than the price the Portfolio
would receive if it sold the security. During such periods, the yield to
investors in the Portfolio may differ somewhat from that obtained in a similar
fund which uses available market quotations to value all of its portfolio
securities.

Trading in securities on many foreign securities exchanges (including European
and Far Eastern securities exchange) and over-the-counter markets is normally
completed before the close of business on each business day in New York (i.e., a
day on which the Exchange is open). In addition, securities trading in a
particular country or countries may not take place on all business days for the
Exchange or may take place on days which are not business days for the Exchange.
Changes in valuations on certain securities may occur at times or on days on
which a Portfolio's net asset value is not calculated and on which a Portfolio
does not effect sales, redemptions and exchanges of its shares. The Portfolio
calculates net asset value per share, and therefore effects sales, redemptions
and exchanges of its shares, as of the close of trading on the Exchange each day
the Exchange is open for trading. Such calculation does not take place
contemporaneously with the determination of the prices of certain foreign
portfolio securities used in such calculation. If events materially affecting
the value of such securities occur between the time when their price is
determined and the time when a Portfolio's net asset value is calculated, such
securities may be valued at fair value as determined in good faith by the
Adviser based in accordance with procedures established by the Trustees.

                              REDEMPTION OF SHARES

Payment for shares tendered for redemption by the insurance company is made
ordinarily in cash within seven days after tender in proper form, except under
unusual circumstances as determined by the SEC. The redemption price will be the
net asset value next determined after the receipt of a request in proper form.
The market values of the securities in each Portfolio are subject to daily
fluctuations and the net asset value per share of each Portfolio's shares will
fluctuate accordingly. Therefore, the redemption value may be more or less than
the investor's cost.

                                   DIVIDENDS,
                                 DISTRIBUTIONS
                                   AND TAXES

All dividends and capital gains distributions of each Portfolio are
automatically reinvested by the Account in additional shares of such Portfolio.

Shares of the Money Market Portfolio and Government Portfolio become entitled to
income distributions declared on the day the shareholder service agent receives
payment of the purchase price in the form of federal funds. Such shares do not
receive income distributions declared on the date of redemption.

DIVIDENDS OF THE MONEY MARKET PORTFOLIO. The Money Market Portfolio declares
income dividends each business day payable monthly. The Money Market Portfolio's
net income for dividend purposes is calculated daily and consists of interest
accrued or discount earned, plus or minus any net realized gains or losses on
portfolio securities, less any amortization of premium and the expenses of the
Money Market Portfolio.

DIVIDENDS AND DISTRIBUTIONS OF THE ASSET ALLOCATION PORTFOLIO, THE COMSTOCK
PORTFOLIO, THE DOMESTIC INCOME PORTFOLIO, THE EMERGING GROWTH PORTFOLIO, THE
ENTERPRISE PORTFOLIO, THE GLOBAL EQUITY PORTFOLIO, THE GOVERNMENT PORTFOLIO, THE
GROWTH AND INCOME PORTFOLIO, THE MORGAN STANLEY REAL ESTATE SECURITIES PORTFOLIO
AND THE STRATEGIC STOCK PORTFOLIO. Dividends from stocks and interest earned
from other investments are the main source of income for these Portfolios.
Substantially all of this income, less expenses, is distributed to Accounts on
an annual basis. When a Portfolio sells portfolio securities, it may realize
capital gains or losses, depending on whether the prices of the securities sold
are higher or lower than the prices the Portfolio paid to purchase them. Net
capital gains represent the excess of net long term capital gains over net
short-term capital losses and any losses carried forward from prior years. Each
of these Portfolios distributes any net capital gains to Accounts no less
frequently than annually.

TAX STATUS OF THE PORTFOLIOS. Each Portfolio has elected to be taxed as a
"regulated investment

                                       63

company" under the Code. By maintaining its qualification as a "regulated
investment company," a Portfolio is not subject to federal income taxes to the
extent it distributes its net investment income and net capital gains. If for
any taxable year a Portfolio does not qualify for the special tax treatment
afforded regulated investment companies, all of its taxable income, including
any net capital gains, would be subject to tax at regular corporate rates
(without any deduction for distributions to shareholders).

TAX TREATMENT TO INSURANCE COMPANY AS SHAREHOLDER. The investments of the
Accounts in the Portfolios are subject to the diversification requirements of
Section 817(h) of the Code, which must be met at the end of each quarter of the
year (or within 30 days thereafter). Regulations issued by the Secretary of the
Treasury have the effect of requiring the Accounts to invest no more than 55% of
their total assets in securities of any one issuer, no more than 70% in the
securities of any two issuers, no more than 80% in the securities of any three
issuers, and no more than 90% in the securities of any four issuers. For this
purpose, the U.S. Treasury and each U.S. Government agency and instrumentality
is considered to be a separate issuer. In the event the investments of the
Accounts in the Portfolios are not properly diversified under Code Section
817(h), then the policies funded by shares of the Portfolios will not be treated
as life insurance for federal income tax purposes and the owners of the policies
will be subject to taxation on their respective shares of the dividends and
distributions paid by the relevant Portfolios.

Dividends paid by each Portfolio from its ordinary income and distributions of
each Portfolio's net short-term capital gains are includable in the insurance
company's gross income. The tax treatment of such dividends and distributions
depends on the insurance company's tax status. To the extent that income of a
Portfolio represents dividends on equity securities rather than interest income,
its distributions are eligible for the 70% dividends received deduction
applicable in the case of a life insurance company as provided in the Code. The
Trust will send to the Accounts a written notice required by the Code
designating the amount and character of any distributions made during such year.

Under the Code, any distributions designated as being made from a Portfolio's
net capital gains are taxable to the insurance company as long-term capital
gains. Such distributions of net capital gains will be designated as capital
gain dividends in a written notice to the Accounts which accompanies the
distribution payments. Capital gain dividends are not eligible for the dividends
received deduction. Ordinary income dividends and capital gain dividends to the
insurance company may also be subject to state and local taxes.

As described in the accompanying prospectus for the Contracts, the insurance
company reserves the right to assess the Account a charge for any taxes paid by
it.

CERTAIN INVESTMENT PRACTICES OF PORTFOLIOS. Certain investment practices of a
Portfolio may be subject to special provisions of the Code that, among other
things, may defer the use of certain losses of the Portfolio and affect the
holding period of the securities held by the Portfolio and the character of the
gains or losses realized by the Portfolio. These provisions may also require the
Portfolio to recognize income or gain without receiving cash with which to make
distributions in the amounts necessary to maintain the Portfolio's qualification
as a regulated investment company and avoid income and excise taxes. Each
Portfolio will monitor its transactions and may make certain tax elections in
order to mitigate the effect of these rules and prevent disqualification of the
Portfolio as a regulated investment company.

                              FINANCIAL HIGHLIGHTS


The financial highlights tables are intended to help you understand the
financial performance of each Portfolio's Class I Shares for the past five
years. Prior to May 1, 2000, each Portfolio issued one class of shares and that
class of shares has been designated as Class I Shares. Certain information
reflects financial results for a single Class I Share of a Portfolio. The total
returns in the table represent the rate that an investor would have earned (or
lost) on an investment in a Portfolio (assuming reinvestment of all dividends
and distributions). This information has been audited by PricewaterhouseCoopers
LLP, independent accountants, whose reports, along with each Portfolio's
financial statements, are included in the Statement of Additional Information
and may be obtained by shareholders without charge by calling the telephone
number on the back cover of this prospectus. This information should be read in
conjunction with the financial statements and notes thereto included in the
Statement of Additional Information.

                                  APPENDIX --
                                 DESCRIPTION OF
                               SECURITIES RATINGS

STANDARD & POOR'S -- A brief description of the applicable Standard & Poor's
(S&P) rating symbols and their meanings (as published by S&P) follow:

A S&P corporate or municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.

The debt rating is not a recommendation to purchase, sell, or hold a security,
inasmuch as it does not comment as to market price or suitability for a
particular investor.

The ratings are based on current information furnished by the issuer or obtained
by S&P from other sources it considers reliable. S&P does not perform an audit
in connection with any rating and may, on occasion, rely on unaudited financial
information. The ratings may be changed, suspended, or withdrawn as a result of
changes in, or unavailability of, such information, or based on other
circumstances.

The ratings are based, in varying degrees, on the following considerations:

1. Likelihood of payment -- capacity and willingness of the obligor to meet its
   financial commitment on an obligation in accordance with the terms of the
   obligation:

2. Nature of and provisions of the obligation:

3. Protection afforded by, and relative position of, the obligation in the event
   of bankruptcy, reorganization, or other arrangement under the laws of
   bankruptcy and other laws affecting creditor's rights.

                     1. LONG-TERM DEBT -- INVESTMENT GRADE

AAA: Debt rated "AAA" has the highest rating assigned by S&P. Capacity to meet
its financial commitment on the obligation is extremely strong.

AA: Debt rated "AA" differs from the highest rated issues only in small degree.
Capacity to meet its financial commitment on the obligation is very strong.

A: Debt rated "A" is somewhat more susceptible to the adverse effects of changes
in circumstances and economic conditions than obligations in higher rated
categories. Capacity to meet its financial commitment on the obligation is still
strong.

BBB: Debt rated "BBB" exhibits adequate protection parameters. However, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity to meet its financial commitment on the obligation.

                               SPECULATIVE GRADE

BB, B, CCC, CC, C: Debts rated "BB", "B", "CCC", "CC" and "C" are regarded as
having significant speculative characteristics. "BB" indicates the least degree
of speculation and "C" the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

BB: Debt rated "BB" is less vulnerable to nonpayment than other speculative
issues. However, it faces major ongoing uncertainties or exposure to adverse
business, financial, or economic conditions which could lead to the obligor's
inadequate capacity to meet its financial commitment on the obligation.

B: Debt rated "B" is more vulnerable to nonpayment than obligations rated "BB",
but the obligor currently has the capacity to meet its financial commitment on
the obligation. Adverse business, financial, or economic conditions will likely
impair the obligor's capacity or willingness to meet its financial commitment on
the obligation.

CCC: Debt rated "CCC" is currently vulnerable to nonpayment, and is dependent
upon favorable business, financial, and economic conditions for the obligor to
meet its financial commitment on the obligation. In the event of adverse
business, financial, or economic conditions, the obligor is not likely to have
the capacity to meet its financial commitment on the obligation.

CC: Debt rated "CC" is currently highly vulnerable to nonpayment.

                                      A- 1
<PAGE>   74

C: The "C" rating may be used to cover a situation where a bankruptcy petition
has been filed or similar action has been taken, but payments on this obligation
are being continued.

D: Debt rated "D" is in payment default. The "D" rating category is used when
payments on an obligation are not made on the date due even if the applicable
grace period has not expired, unless S&P believes that such payments will be
made during such grace period. The "D" rating also will be used upon the filing
of a bankruptcy petition or the taking of a similar action if payments on an
obligation are jeopardized.

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

r: This symbol is attached to the ratings of instruments with significant
noncredit risks. It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk -- such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS TERRITORIES are
rated on the same basis as domestic corporate and municipal issues. The ratings
measure the creditworthiness of the obligor but do not take into account
currency exchange and related uncertainties.

BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain ratings or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies and fiduciaries generally.

                              2. COMMERCIAL PAPER

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

Ratings are graded into several categories, ranging from "A-1" for the highest
quality obligations to "D" for the lowest. These categories are as follows:

A-1: The highest category indicates that the degree of safety regarding timely
payment is strong. Those issues determined to possess extremely strong safety
characteristics are denoted with a plus sign (+) designation.

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

A-3: Issues carrying this designation have adequate capacity for timely payment.
They are, however, more vulnerable to the adverse effects of changes in
circumstances than obligations carrying the higher designations.

B: Issues rated "B" are regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

C: This rating is assigned to short-term debt obligations currently vulnerable
to nonpayment and is dependent upon favorable business, financial, and economic
conditions for the obligor to meet its financial commitment on the obligation.

D: Debt rated "D" is in payment default. The "D" rating category is used when
interest payments or principal payments are not made on the date due, even if
the applicable grace period has not expired, unless S&P believes that such
payments will be made during such grace period. The "D" rating also will be used
upon the filing of a bankruptcy petition or the taking of a similar action if
payments on an obligation are jeopardized.

A commercial paper rating is not a recommendation to purchase, sell or hold a
security inasmuch as it does not comment as to market price or suitability for a
particular investor. The ratings are based on current information furnished to
S&P by the issuer or obtained from other sources it considers reliable. S&P does
not perform an audit in connection with any rating and may, on occasion, rely on
unaudited financial information. The ratings may be changed, suspended or

                                      A- 2
<PAGE>   75

withdrawn as a result of changes in, or unavailability of, such information, or
based on other circumstances.

                               3. PREFERRED STOCK

A S&P preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations. A preferred stock rating differs from a bond rating inasmuch as it
is assigned to an equity issue, which issue is intrinsically different from, and
subordinated to, a debt issue. Therefore, to reflect this difference, the
preferred stock rating symbol will normally not be higher than the bond rating
symbol assigned to, or that would be assigned to, the senior debt of the same
issuer.

The preferred stock ratings are based on the following considerations:

i. Likelihood of payment-capacity and willingness of the issuer to meet the
timely payment of preferred stock dividends and any applicable sinking fund
requirements in accordance with the terms of the obligation.

ii. Nature of, and provisions of, the issuer.

iii. Relative position of the issue in the event of bankruptcy, reorganization,
or other arrangements under the laws of bankruptcy and other laws affecting
creditors' rights.

AAA: This is the highest rating that may be assigned by S&P to a preferred stock
issue and indicates an extremely strong capacity to pay the preferred stock
obligations.

AA: A preferred stock issue rated "AA" also qualifies as a high-quality, fixed
income security. The capacity to pay preferred stock obligations is very strong,
although not as overwhelming as for issues rated "AAA".

A: An issue rated "A" is backed by a sound capacity to pay the preferred stock
obligations, although it is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions.

BBB: An issue rated "BBB" is regarded as backed by an adequate capacity to pay
the preferred stock obligations. Whereas it normally exhibits adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to make payments for a preferred
stock in this category than for issues in the "A" category.

BB, B and CCC: Preferred stock rated "B", "B", and "CCC" are regarded, on
balance, as predominantly speculative with respect to the issuer's capacity to
pay preferred stock obligations.

"BB" indicates the lowest degree of speculation and "CCC" the highest. While
such issues will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions.

CC: The rating "CC" is reserved for a preferred stock issue in arrears on
dividends or sinking fund payments, but that is currently paying.

C: A preferred stock rated "C" is a nonpaying issue.

D: A preferred stock rated "D" is a nonpaying issue with the issuer in default
on debt instruments.

NR: This indicates that no rating has been requested, that there is insufficient
information on which to base a rating, or that S&P does not rate a particular
type of obligation as a matter of policy. PLUS (+) or MINUS (-): To provide more
detailed indications of preferred stock quality, ratings from "AA" to "CCC" may
be modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

A preferred stock rating is not a recommendation to purchase, sell, or hold a
security inasmuch as it does not comment as to market price or suitability for a
particular investor. The ratings are based on current information furnished to
S&P by the issuer or obtained by S&P from other sources it considers reliable.
S&P does not perform an audit in connection with any rating and may, on
occasion, rely on unaudited financial information. The ratings may be changed,
suspended, or withdrawn as a result of changes in, or unavailability of, such
information, or based on other circumstances.

MOODY'S INVESTORS SERVICE  -- a brief description of the applicable Moody's
Investors Service (Moody's) rating symbols and their meanings (as published by
Moody's Investor Service) follows:

                               1. LONG-TERM DEBT

Aaa: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edged." Interest payments are protected by a large or

                                      A- 3
<PAGE>   76

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 the Aaa securities.

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

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

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
during both 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 the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long 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 marked 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 to B. The modifier 1 indicates that the issue 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.

ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.

Should no rating be assigned, the reason may be one of the following:

1. An application for rating was not received or accepted.

2. The issue or issuer belongs to a group of securities that are not rated as a
   matter of policy.

3. There is a lack of essential data pertaining to the issue or issuer.

4. The issue was privately placed, in which case the rating is not published in
   Moody's publications.

Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.

                               2. SHORT-TERM DEBT

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

Moody's employs the following three designations, all judged to be investment
grade, to indicate the relative repayment ability of rated issues:

Issuers rated Prime-1 (or supporting institutions) have a superior ability for
repayment of senior short-term debt obligations. Prime-1 repayment ability will
often be evidenced by many of the following characteristics:

- -- Leading market positions in well-established industries.

                                      A- 4
<PAGE>   77

- -- High rates of return on funds employed.

- -- Conservative capitalization structure with moderate reliance on debt and
   ample asset protection.

- -- Broad margins is earnings coverage of fixed financial charges and high
   internal cash generation.

- -- Well-established access to a range of financial markets and assured sources
   of alternate liquidity.

Issuers rated Prime-2 (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations. This will normally be evidenced
by many of the characteristics cited above but to a lesser degree. Earnings
trends and coverage ratios, while sound, may be more subject to variation.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternate liquidity is maintained.

Issuers rated Prime-3 (or supporting institutions) have an acceptable ability
for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes of the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

                               3. PREFERRED STOCK

Preferred stock rating symbols and their definitions are as follows:

AAA: As issue which is rated "AAA" is considered to be a top-quality preferred
stock. This rating indicates good asset protection and the least risk of
dividend impairment within the universe of preferred stocks.

AA: An issue which is rated "AA" is considered a high-grade preferred stock.
This rating indicates that there is a reasonable assurance the earnings and
asset protection will remain relatively well maintained in the foreseeable
future.

A: An issue which is rated "A" is considered to be an upper-medium-grade
preferred stock. While risks are judged to be somewhat greater than in the "AAA"
and "AA" classifications, earnings and asset protections are, nevertheless,
expected to be maintained at adequate levels.

BAA: An issue which is rated "BAA" is considered to be a medium-grade preferred
stock, neither highly protected nor poorly secured. Earnings and asset
protection appear adequate at present but may be questionable over any great
length of time.

BA: An issue which is rated "BA" is considered to have speculative elements and
its future cannot be considered well assured. Earnings and asset protection may
be very moderate and not well safeguarded during adverse periods. Uncertainty of
position characterizes preferred stocks in this class.

B: An issue which is rated "B" generally lacks the characteristics of a
desirable investment. Assurance of dividend payments and maintenance of other
terms of the issue over any long period of time may be small.

CAA: An issue which is rated "CAA" is likely to be in arrears on dividend
payments. This rating designation does not purport to indicate the future status
of payments.

CA: An issue which is rated "CA" is speculative in a high degree and is likely
to be in arrears on dividends with little likelihood of eventual payment.

C: This is the lowest rated class of preferred or preference stock. Issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

Moody's applies numerical modifiers 1, 2 and 3 in each rating classification.
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.

                           ASSET ALLOCATION PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Asset Allocation Portfolio is a mutual fund with an investment objective to
seek high total investment return consistent with prudent investment risk
through a fully managed investment policy utilizing equity securities as well as
investment grade intermediate- and long-term debt securities and money market
securities. Total investment return consists of current income (including
dividends, interest and discount accruals) and capital appreciation or
depreciation. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing in a portfolio of equity securities,
investment grade intermediate- and long-term debt securities, including
preferred stocks, convertible preferred stocks and convertible debt securities,
and money market securities. The composition of the Portfolio will vary from
time to time to reflect the investment adviser's views on economic and market
trends and the anticipated relative total investment return available from a
particular type of security. The Portfolio may invest up to 25% of its total
assets in securities of foreign issuers. The Portfolio may invest in certain
derivatives, such as options and futures, which may subject the Portfolio to
additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. The prices of
the Portfolio's equity securities may or may not fluctuate in tandem with
overall changes in the stock markets. The prices of debt securities tend to fall
as interest rates rise, and such declines may be greater among securities with
longer maturities. The prices of convertible securities are affected by changes
similar to those of debt and equity securities. The value of a convertible
security tends to decline as interest rates rise and, because of the conversion
feature, tends to vary with fluctuations in the market value of the underlying
common stock.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Because the Portfolio generally invests in investment
grade-quality debt securities, it is subject to a lower level of credit risk
than a portfolio investing more in lower-grade quality securities.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                        3
<PAGE>   83

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek high total investment return over the long term.

- - Can withstand volatility in the value of their shares in the Portfolio.

- - Wish to add to their personal investment holdings a portfolio that invests in
  a varying mix of equity, debt securities and money market securities seeking
  high total investment return.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio* over the past ten calendar years prior to the date of
this prospectus. Sales charges or other expenses at the contract level are not
reflected in this chart. If sales charges or other expenses at the contract
level had been included, the returns shown below would have been lower. Remember
that the past performance of the Portfolio is not indicative of its future
performance.

</TABLE>


* The Portfolio commenced offering Class II Shares on May 1, 2000. The returns
  shown in the Annual Performance chart above (and in the Comparative
  Performance chart below) are for the Class I Shares of the Portfolio (which
  are offered in a separate prospectus). The annual return variability of the
  Portfolio's Class II Shares would be substantially similar to that shown for
  the Class I Shares because all of the Portfolio's shares are invested in the
  same portfolio of securities; however, the actual annual returns of the Class
  II Shares would be lower than the annual returns shown for the Portfolio's
  Class I Shares because of differences in the expenses borne by each class of
  shares.


During the ten-year period shown in the bar chart, the highest quarterly return
was 11.04% (for the quarter ended December 31, 1998) and the lowest quarterly
return was -7.45% (for the quarter ended September 30, 1990).

                            COMPARATIVE PERFORMANCE


This table shows how the Portfolio's performance compares with the Standard &
Poor's 500-Stock Index, a broad-based market index that the Portfolio's
management believes is an applicable benchmark for the Portfolio, and with the

* The Portfolio commenced offering Class II shares on May 1, 2000. The returns
  shown in the Comparative Performance chart above are for the Class I Shares of
  the Portfolio (which are offered in a separate prospectus). The annual return
  variability of the Portfolio's Class II Shares would be substantially similar
  to that shown for the Class I Shares because all of the Portfolio's shares are
  invested in the same portfolio of securities; however, the actual annual
  returns of the Class II Shares would be lower than the annual returns shown
  for the Portfolio's Class I Shares because of differences in the expenses
  borne by each class of shares.

                               COMSTOCK PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Comstock Portfolio is a mutual fund with an investment objective to seek
capital growth and income through investments in equity securities, including
common stocks, preferred stocks and securities convertible into common and
preferred stocks. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing in a portfolio of equity securities,
consisting principally of common stocks. The Portfolio emphasizes a "value"
style of investing seeking well-established, undervalued companies believed to
possess the potential for capital growth and income. The Portfolio may invest up
to 15% of its total assets in securities of foreign issuers. The Portfolio may
invest in certain derivatives, such as options and futures, which may subject
the Portfolio to additional risks.

                                INVESTMENT RISKS

Investors who seek only long-term capital growth should be aware that the
Portfolio also seeks to generate income and that capital growth is only a part
of the Portfolio's overall investment objective. Similarly, investors who seek a
more assured level of current income should be aware that the Portfolio's income
will fluctuate and that seeking income is only a part of the Portfolio's overall
investment objective.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. A "value"
style of investing emphasizes undervalued companies with characteristics for
improved valuations. This style of investing is subject to the risks that the
valuations never improve or that the returns on "value" equity securities are
less than the returns on other styles of investing or the overall stock markets.
During an overall stock market decline, stock prices of small- or medium-sized
companies (in which the Portfolio may invest) often fluctuate more than prices
of larger companies. The ability of the Portfolio's investment holdings to
generate income depends on the earnings and the continuing declaration of
dividends by the issuers of such securities.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek capital growth and income over the long term.

                                        5
<PAGE>   85

- - Can withstand volatility in the value of their shares of the Portfolio.

- - Wish to add to their personal investment holdings a portfolio that emphasize a
  "value" style of investing in equity securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.


The Comstock Portfolio commenced investment operations as of April 30, 1999.
Accordingly, the Portfolio does not have a full calendar year of historical
annual performance or comparative performance to provide to investors.

                              RISK/RETURN SUMMARY

                             INVESTMENT OBJECTIVES

The Domestic Income Portfolio is a mutual fund with a primary investment
objective to seek current income. When consistent with the primary investment
objective, capital appreciation is a secondary investment objective. There can
be no assurance that the Portfolio will achieve its investment objectives.

                             INVESTMENT STRATEGIES

The Portfolio's management seeks to achieve the investment objectives by
investing primarily in a diversified portfolio of income securities, including
convertible and non-convertible debt securities and preferred stocks. Under
normal market conditions, the Portfolio invests at least 80% of its total assets
in income securities rated at the time of purchase B or higher by Standard &
Poor's ("S&P") or rated B or higher by Moody's Investors Service, Inc.
("Moody's") or unrated securities judged by the Portfolio's investment adviser
to be of comparable quality at the time of purchase. Securities rated BB or
below by S&P or rated Ba or below by Moody's or unrated securities of comparable
quality are commonly referred to as "junk bonds" and involve special risks as
compared to investments in higher-grade securities (see sidebar for an
explanation of quality ratings). The Portfolio may invest up to 25% of its total
assets in securities of foreign issuers. The Portfolio may purchase or sell
securities on a when-issued or delayed delivery basis.

                               UNDERSTANDING
                              QUALITY RATINGS

Security ratings are based on the issuer's ability to pay interest and repay
the principal. Securities with ratings above the line are considered
"investment grade," while those with ratings below the line are regarded as
"noninvestment grade," or "junk bonds." A detailed explanation of these
ratings can be found in the appendix to this prospectus.

                                INVESTMENT RISKS

With its holdings of medium- and lower-grade securities, the Portfolio has
greater risks than a portfolio owning only higher-grade securities.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. The prices of income securities tend to
fall as interest rates rise and such declines tend to be greater among
securities with longer durations. Although the Portfolio has no policy limiting
the maturities of its investments, the Portfolio's investment adviser seeks to
maintain the dollar-weighted average duration of the Portfolio between four to
six years. This means the Portfolio generally will be subject to greater market
risk than a portfolio that owns only shorter term securities but lesser market
risk than a portfolio that owns only longer term securities. Lower-grade
securities, especially those with longer durations or that do not make regular
interest payments, may fluctuate more in price in response to negative issuer or
general economic news than higher-grade securities. When-issued and

                                        7
<PAGE>   87

delayed delivery transactions are subject to changes in market conditions from
the time of the commitment until settlement. This may adversely affect the
prices or yields of the securities being purchased, as well as any portfolio
securities held for payment of such commitments. The greater the Portfolio's
outstanding commitments for these securities, the greater the Portfolio's
exposure to market price fluctuation.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Because the Portfolio may invest in securities with
below investment grade credit quality, the Portfolio is subject to a higher
level of credit risk than a portfolio that buys only investment grade
securities. The credit quality of "noninvestment grade" securities is considered
speculative by recognized rating agencies with respect to the issuer's
continuing ability to pay interest and principal. Lower-grade securities may
have less liquidity and a higher incidence of default than investments in
higher-grade securities. The Portfolio may incur higher expenditures to protect
the Portfolio's interest in such securities. The credit risks and market prices
of lower-grade securities are more sensitive to negative issuer developments,
such as reduced revenues or increased expenditures, or adverse economic
conditions, such as a recession, than higher-grade securities.

INCOME RISK. The income you receive from the Portfolio is based primarily on
interest rates, which can vary widely over the short and long term. If interest
rates drop, your income from the Portfolio may drop as well.

CALL RISK. If interest rates fall, it is possible that issuers of securities
with high interest rates will prepay or "call" their securities before their
maturity dates. In this event, the proceeds from the called securities would be
reinvested by the Portfolio in securities with the new, lower interest rates,
resulting in a possible decline in the Portfolio's income and distributions to
shareholders.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objectives and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek current income and capital appreciation over the long term.

- - Are willing to take on the increased risks of medium- and lower-grade
  securities in exchange for potentially higher income.

- - Wish to add to their personal investment holdings a portfolio that invests
  primarily in income securities, including medium- and lower-grade income
  securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio* over the past ten calendar years prior to the date of
this prospectus. Sales charges or other expenses at the contract level are not
reflected in this chart. If sales charges or other expenses at the contract
level had been included, the returns shown below would have been lower. Remember
that the past performance of the Portfolio is not indicative of its future
performance.

* The Portfolio commenced offering Class II Shares on May 1, 2000. The returns
  shown in the Annual Performance chart above (and in the Comparative
  Performance chart below) are for the Class I Shares of the Portfolio (which
  are offered in a separate prospectus). The annual return variability of the
  Portfolio's Class II Shares would be substantially similar to that shown for
  the Class I Shares because all of the Portfolio's shares are invested in the
  same portfolio of securities; however, the actual annual returns of the Class
  II Shares would be lower than the annual returns shown for the Portfolio's
  Class I Shares because of differences in the expenses borne by each class of
  shares.

During the ten-year period shown in the bar chart, the highest quarterly return
was 7.16% (for the quarter ended June 30, 1995) and the lowest quarterly return
was -8.33% (for the quarter ended December 31, 1989).

                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE


The Emerging Growth Portfolio is a mutual fund with an investment objective to
seek capital appreciation. There can be no assurance that the Portfolio will
achieve its investment objective.


                             INVESTMENT STRATEGIES


Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the Portfolio's investment objective by investing at least 65% of the
Portfolio's total assets in common stocks of emerging growth companies. Emerging
growth companies are those companies in the early stages of their life cycles
that the Portfolio's investment adviser believes have the potential to become
major enterprises. Investing in such companies involves risks not ordinarily
associated with investments in larger, more established companies. The Portfolio
may invest up to 20% of its total assets in securities of foreign issuers. The
Portfolio may invest in certain derivatives, such as options and futures, which
may subject the Portfolio to additional risks.


                                INVESTMENT RISKS


An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.



MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. During an
overall market decline, stock prices of small- and medium-sized companies (in
which the Portfolio may invest) often fluctuate more and often fall more than
the prices of larger sized company stocks. It is possible that the stocks of
small-and medium-sized companies will be more volatile and underperform the
overall stock market. Historically, smaller- and medium-sized company stocks
have sometimes gone through extended periods when they did not perform as well
as larger company stocks.


RISKS OF EMERGING GROWTH COMPANIES. Companies that the Portfolio's management
believe are emerging growth companies are often companies with limited product
lines, markets, distribution channels or financial resources and the management
of such companies may be dependent upon one or a few key people. The stocks of
emerging growth companies can therefore be subject to more abrupt or erratic
market movements than stocks of larger, more established companies or the stock
market in general.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

* The Portfolio commenced offering Class II Shares on May 1, 2000. The returns

                              ENTERPRISE PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Enterprise Portfolio is a mutual fund with an investment objective to seek
capital appreciation through investments in securities believed by the
Portfolio's investment adviser to have above average potential for capital
appreciation. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing primarily in common stocks of "growth"
companies focusing on those securities believed to offer a combination of strong
business fundamentals at an attractive valuation. The Portfolio may invest up to
10% of its total assets in securities of foreign issuers. The Portfolio may
invest in certain derivatives, such as options and futures, which may subject
the Portfolio to additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in common
stocks generally are affected by changes in the stock markets, which fluctuate
substantially over time, sometimes suddenly and sharply. The Portfolio
emphasizes a "growth" style of investing. The market values of "growth" common
stocks may be more volatile than other types of investments. The returns on
"growth" securities may or may not move in tandem with the returns on other
styles of investing or the overall stock markets. During an overall stock market
decline, stock prices of small- or medium-sized companies (in which the
Portfolio may invest) often fluctuate more than prices of larger companies.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek capital appreciation over the long term.

- - Do not seek current income from their investment.

- - Can withstand substantial volatility in the value of their shares of the
  Portfolio.

- - Wish to add to their personal investment holdings a portfolio that emphasizes
  a "growth" style of investing in common stocks.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term

                                       13

investment, and the Portfolio should not be used as a trading vehicle.

                               ANNUAL PERFORMANCE

One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio* over the past ten calendar years prior to the date of
this prospectus. Sales charges or other expenses at the contract level are not
reflected in this chart. If sales charges or other expenses at the contract
level had been included, the returns shown below would have been lower. Remember
that the past performance of the Portfolio is not indicative of its future
performance.

                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Global Equity Portfolio is a mutual fund with an investment objective to
seek long-term growth of capital through investments in an internationally
diversified portfolio of equity securities of companies of any nation including
the United States. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

The Portfolio's management seeks to achieve the investment objective by
investing in an internationally diversified portfolio of equity securities,
including common stocks, preferred stocks and warrants or options to acquire
such securities. The Fund's management uses a "top-down" investment management
approach that emphasizes country selection and weighting rather than individual
security selection. Within a particular country, the Portfolio selects
securities of issuers that would replicate a broad market index for that
country. The Portfolio may invest in any country, including developed or
undeveloped countries. Under normal market conditions, the Portfolio invests at
least 65% of its total assets in securities of issuers of at least three
countries (including the United States). Investments in securities of foreign
issuers include certain risks not typically associated with investments in U.S.
securities. The Portfolio may invest in certain derivatives, such as options and
futures, which may subject the Portfolio to additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. Foreign
markets may, but often do not, move in tandem with changes in U.S. markets, and
foreign markets may have more price volatility than U.S. markets. During an
overall stock market decline, stock prices of small- and medium-sized companies
(in which the Portfolio may invest) often fluctuate more than prices of larger
companies.

FOREIGN RISKS. Because the Portfolio will own securities from foreign issuers,
it will be subject to risks not usually associated with owning securities of
U.S. issuers. These risks can include fluctuations in foreign currencies,
foreign currency exchange controls, political and economic instability,
differences in financial reporting, differences in securities regulation and
trading, and foreign taxation issues. The risks of investing in developing or
emerging markets (in which the Portfolio may invest) are greater than the risks
generally associated with foreign investments including greater political
uncertainties, an economy's dependence on international development assistance,
currency transfer restrictions, and greater delays and disruptions in settlement
transactions.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

<PAGE>   95

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Fund may be appropriate
for investors who:

- - Seek long-term growth of capital.

- - Are willing to take on the increased risks associated with investing in
  foreign securities.

- - Can withstand volatility in the value of their shares in the Portfolio.

- - Wish to add to their personal investment holdings a portfolio that invests in
  an international portfolio of equity securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio* over the past four calendar years prior to the date of

reflected in this chart. If sales charges or other expenses at the contract
level had been included, the returns shown below would have been lower. Remember
that the past performance of the Portfolio is not indicative of its future
performance.

                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Government Portfolio is a mutual fund with an investment objective to seek
to provide investors with high current return consistent with preservation of
capital. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing at least 80% of the Portfolio's total assets
in debt securities issued or guaranteed by the U.S. government, its agencies or
its instrumentalities, including mortgage-related securities issued or
guaranteed by agencies or instrumentalities of the U.S. government. Under normal
market conditions, the Portfolio may invest up to 20% of its total assets in
government-related securities, including privately issued mortgage-related and
mortgage-backed securities not directly issued or guaranteed by
instrumentalities of the U.S. government, privately issued certificates
representing "stripped" U.S. government or mortgage-related securities and
repurchase agreements fully collateralized by U.S. government securities. The
Portfolio may invest in certain derivatives, such as options, futures and
options on futures, and interest rate swaps or other interest rate-related
transactions, which may subject the Portfolio to additional risks. The Portfolio
may purchase or sell securities on a when-issued or delayed delivery basis.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. The value of debt securities tend to fall
as interest rates rise and such declines tend to be greater among debt
securities with longer maturities or longer durations. Although the Portfolio
has no policy limiting the maturities of its investments, the Portfolio's
management seeks to moderate market risk by normally maintaining a portfolio
duration of four to six years. This means that the Portfolio will be subject to
greater market risk than a portfolio investing solely in shorter-term securities
but lesser market risk than a portfolio investing solely in longer-term
securities (see sidebar for an explanation of maturities and durations). The
yields and market prices of U.S. government securities may move differently and
adversely compared to the yields and market prices of the overall securities
markets. These securities, while backed by the U.S. government, are not
guaranteed against declines in their market prices.

The prices of mortgage-related securities, like traditional debt securities,
tend to fall as interest rates rise. Mortgage-related securities may be more
susceptible to further price declines than traditional debt securities in
periods of rising interest rates because of extension risk (described below).
Additionally, mortgage-related securities may benefit less than traditional debt
securities during periods of declining interest rates because of prepayment risk
(described below).

Market risk is often greater among certain types of debt securities, such as
zero-coupon securities or mortgage-related stripped securities, which do not
make regular or periodic interest payments. As interest rates change, these
securities often fluctuate more in price than securities that make current
interest payments. Therefore, the Portfolio may be subject to greater market
risk than a portfolio that does not own these types of securities.

Investments in when-issued and delayed delivery transactions are subject to
changes in market conditions from the time of the commitment until settlement.
This may adversely affect the prices or yields of the securities being
purchased, as well as any portfolio securities held for payment of such
commitments. The greater the Portfolio's outstanding commitments for these
securities, the greater the Portfolio's exposure to market price fluctuation.

                                     MATURITIES

    A debt security can be categorized according to its maturity, which is the
    length of time before the issuer must repay the principal.

                                 UNDERSTANDING
                                    DURATION

    Duration provides an alternative approach to assessing a security's market
    risk. Duration measures the expected life of a security by incorporating the
    security's yield, coupon interest payments, final maturity and call features
    into one measure. While maturity focuses only on the final principal
    repayment date of a security, duration looks at the timing and present value
    of all of a security's principal, interest or other payments. Typically, a
    debt security with interest payments due prior to maturity has a duration
    less than maturity. A zero-coupon bond, which does not make interest
    payments prior to maturity, would have the same duration and maturity.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Credit risk should be low for the Portfolio because
it invests substantially all of its assets in U.S. government securities.

INCOME RISK. The income you receive from the Portfolio is based primarily on
interest rates, which can vary widely over the short and long term. If interest
rates drop, your income from the Portfolio may drop as well. The more the
Portfolio invests in adjustable, variable or floating rate securities or in
securities susceptible to prepayment risk, the greater the Portfolio's income
risk.

PREPAYMENT RISK. If interest rates fall, the principal on debt securities held
by the Portfolio may be paid earlier than expected. If this happens, the
proceeds from a prepaid security would be reinvested by the Portfolio in
securities bearing the new, lower interest rates, resulting in a possible
decline in the Portfolio's income and distributions to shareholders.

The Portfolio may invest in mortgage-related securities, which are especially
sensitive to prepayment risk because property owners often refinance their
mortgages when interest rates drop.

EXTENSION RISK. The value of debt securities tends to fall as interest rates
rise. For mortgage-related securities, if interest rates rise, property owners
may prepay mortgages more slowly than expected when the security was purchased
by the Portfolio which may further reduce the market value of such security and
lengthen the duration of the security.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options, futures and options on futures, interest
rate swaps and other interest-rate related transactions are examples of
derivatives. Such transactions involve risks different from the direct
investment in underlying securities such as imperfect correlation between the
value of the instruments and the underlying assets; risks of default by the
other party to certain transactions; risks that the transactions may result in
losses that partially or completely offset gains in portfolio positions; risks
that the transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek high current return consistent with preservation of capital.

- - Wish to add to their personal investment holdings a portfolio that invests
  primarily in debt securities issued or guaranteed by the U.S. government, its
  agencies or its instrumentalities.

                                       18

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio* over the past ten calendar years prior to the date of
this prospectus. Sales charges or other expenses at the contract level are not
reflected in this chart. If these sales charges or other expenses at the
contract level had been included, the returns shown below would have been lower.
Remember that the past performance of the Portfolio is not indicative of its
future performance.

                                   PORTFOLIO
                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Growth and Income Portfolio is a mutual fund with an investment objective to
seek long-term growth of capital and income. There can be no assurance that the
Portfolio will achieve its investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing primarily in income-producing equity
securities, including common stocks and convertible securities; although
investments are also made in non-convertible preferred stocks and debt
securities. In selecting securities for investments the Portfolio focuses
primarily on the security's potential for growth of capital and income. The
Portfolio's management may focus on larger capitalization companies which it
believes possess characteristics for improved valuation. The Portfolio may
invest up to 15% of its total assets in securities of foreign issuers. The
Portfolio may invest in certain derivatives, such as options and futures, which
may subject the Portfolio to additional risks.

                                INVESTMENT RISKS

Investors who seek a more assured level of current income should be aware that
the Portfolio's income will fluctuate and that seeking income is only a part of
the Portfolio's overall investment objective. Similarly, investors who seek only
long-term growth should be aware that the Portfolio seeks to generate income and
that long-term growth of capital is only a part of the Portfolio's overall
investment objective.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. During an
overall stock market decline, stock prices of small- or medium-sized companies
or newly-formed companies (in which the Portfolio may invest) often fluctuate
more than prices of larger, more established companies. The ability of the
Portfolio's equity securities holdings to generate income is dependent on the
earnings and the continuing declaration of dividends by the issuers of such
securities. The values of income-producing equity securities may or may not
fluctuate in tandem with overall changes in the stock markets. The Portfolio's
investments in fixed income or debt securities generally are affected by changes
in interest rates and creditworthiness of the issuer. The market prices of such
securities tend to fall as interest rates rise, and such declines may be greater
among securities with longer duration. The Portfolio's investments in
convertible securities are affected by changes similar to those of equity and
debt securities. The value of convertible securities tends to decline as
interest rates rise and, because of the conversion feature, tends to vary with
fluctuations in the market value of the underlying equity security.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; and risks that the
transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek growth of capital and income over the long term.

- - Can withstand volatility in the value of their shares of the Portfolio.

- - Wish to add to their personal investment holding a portfolio that invests
  primarily in income-producing equity securities.

An investment in the Portfolio may not be appropriate for all investors. The
Portfolio is not intended to be a complete investment program, and investors
should consider their long-term investment goals and financial needs when making
an investment decision about the Portfolio. An investment in the Portfolio is
intended to be a long-term investment, and the Portfolio should not be used as a
trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio* over the past three calendar years prior to the date
of this prospectus. Sales charges or other expenses at the contract level are
not reflected in this chart. If sales charges or other expenses at the contract
level had been included, the returns shown below would have been lower. Remember
that the past performance of the Portfolio is not indicative of its future
performance.

                              INVESTMENT OBJECTIVE

The Money Market Portfolio is a mutual fund with an investment objective to seek
protection of capital and high current income through investments in money
market instruments. There can be no assurance that the Portfolio will achieve
its investment objective.

                             INVESTMENT STRATEGIES

The Portfolio seeks to maintain a constant net asset value of $1.00 per share by
investing in a diversified portfolio of money market instruments maturing within
one year with a dollar-weighted average maturity of 90 days or less. The
Portfolio seeks high current income from these short-term investments to the
extent consistent with protection of capital.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks.

INCOME RISK. The income you receive from the Portfolio is based primarily on
short-term interest rates, which can vary widely over time. If short-term
interest rates drop, your income from the Portfolio may drop as well.

CREDIT RISK. Credit risk refers to an issuer's ability to make timely payments
of interest and principal. Credit risk should be low for the Portfolio because
it invests in high-quality money market instruments.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. An investment in the Portfolio is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency. Although the Portfolio seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in the
Portfolio.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek protection of capital and high current income through investments in
  money market instruments.

                               ANNUAL PERFORMANCE

One way to measure the risks of investing in the Portfolio is to look at how its

* The Portfolio commenced offering Class II Shares on May 1, 2000. The returns
  shown in the Annual Performance chart above (and in the Comparative
  Performance chart below) are for the Class I Shares of the Portfolio (which
  are offered in a separate prospectus). The annual return variability of the
  Portfolio's Class II Shares would be substantially similar to that shown for
  the Class I Shares because all of the Portfolio's shares are invested in the
  same portfolio of securities; however, the actual annual returns of the Class
  II Shares would be lower than the annual returns shown for the Portfolio's
  Class I Shares because of differences in the expenses borne by each class of
  shares.


During the ten-year period shown in the bar chart, the highest quarterly return
was 2.34% (for the quarter ended June 30, 1989) and the lowest quarterly return
was 0.65% (for the quarter ended June 30, 1993).

                                 MORGAN STANLEY
                                  REAL ESTATE
                              SECURITIES PORTFOLIO
                              RISK/RETURN SUMMARY

                             INVESTMENT OBJECTIVES

The Morgan Stanley Real Estate Securities Portfolio is a mutual fund with a
primary investment objective to seek long-term growth of capital. Current income
is a secondary investment objective. There can be no assurance that the
Portfolio will achieve its investment objectives.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objectives by investing at least 65% of the Portfolio's total assets
in a portfolio of securities of companies operating in the real estate industry,
including equity securities of real estate investment trusts ("REITs") and other
securities of real estate operating companies. The Portfolio's management
diversifies its investments as to issuers, property types and regions. The
Portfolio's management emphasizes a bottom-up stock selection with a top-down
asset allocation overlay. A company operating in the real estate industry is one
that derives at least 50% of its assets, gross income or net profits from the
ownership, construction, management or sale of residential, commercial or
industrial real estate. Besides equity securities of REITs, the Portfolio may
invest in equity securities, including common stocks and convertible securities,
or non-convertible preferred stocks and investment-grade quality securities of
companies operating in the real estate industry. The Portfolio may invest up to
35% of its total assets in securities of companies outside the real estate
industry. The Portfolio may invest up to 25% of its total assets in securities
of foreign issuers, some or all of which may be in the real estate industry. The
Portfolio may invest in certain derivatives, such as options and futures, which
may subject the Portfolio to additional risks.

                                INVESTMENT RISKS

Because of the Portfolio's policy of concentrating its investments in securities
of companies operating in the real estate industry, the Portfolio is subject to
certain risks associated with the ownership of real estate and with the real
estate industry in general.

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. The prices of
equity securities of companies in the real estate industry may be more volatile
and may not fluctuate in tandem with overall changes in the stock markets. The
value of debt securities tend to fall as interest rates rise, and such declines
may be greater among securities with longer maturities.

RISKS OF INVESTING IN REAL ESTATE. Because of the Portfolio's policy of
concentrating its of investments in securities of companies operating in the
real estate industry and because a substantial portion of the Portfolio's
investments may be comprised of REITs, the Portfolio is more susceptible to
risks associated with the ownership of real estate and with the real estate
industry in general. These risks can include fluctuations in the value of
underlying properties; defaults by borrowers or tenants; market saturation;
changes in general and local economic conditions; decreases in market rates for
rents; increases in competition, property taxes, capital expenditures, or
operating expenses; and other economic, political or regulatory occurrences
affecting the real estate industry. In addition, REITs depend upon specialized
management skills, may have limited financial resources, may have less trading
volume and may be subject to more abrupt or erratic price movements than the
overall securities markets. REITs must comply with certain federal income tax
law requirements to maintain their federal income tax status. Some REITs
(especially mortgage REITs) are affected by risks similar to those associated
with investments in debt securities including changes in interest rates and the
quality of credit extended.

FOREIGN RISKS. Because the Portfolio may own securities from foreign issuers, it
may be subject to risks not usually associated with owning securities of U.S.
issuers. These risks can include fluctuations in foreign currencies, foreign
currency exchange controls, political and economic instability, differences in
financial reporting, differences in securities regulation and trading, and
foreign taxation issues.

<PAGE>   105

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options, futures, and forward contracts are
examples of derivatives. Such transactions involve risks different from the
direct investment in underlying securities, such as imperfect correlation
between the value of the instruments and the underlying assets; risks of default
by the other party to certain transactions; risks that the transactions may
result in losses that partially or completely offset gains in portfolio
positions; risks that the transactions may not be liquid; and manager risk.

MANAGER RISK. As with any managed fund, the Portfolio's management may not be
successful in selecting the best-performing securities and the Portfolio's
performance may lag behind that of similar funds.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek to grow their capital over the long term.

- - Are willing to take on the increased risks of an investment concentrated in
  securities of companies that operate within the same industry.

- - Can withstand volatility in the value of their shares of the Portfolio.

- - Wish to add to their personal investment holdings a portfolio that invests
  primarily in companies operating in the real estate industry.

Investors should carefully consider the additional risks associated with the
Portfolio's policy of concentrating its investments in securities of companies
operating in the real estate industry. An investment in the Portfolio may not be
appropriate for all investors. The Portfolio is not intended to be a complete
investment program, and investors should consider their long-term investment
goals and financial needs when making an investment decision about the
Portfolio. An investment in the Portfolio is intended to be a long-term
investment and the Portfolio should not be used as a trading vehicle.

                               ANNUAL PERFORMANCE


One way to measure the risks of investing in the Portfolio is to look at how its
performance varies from year to year. The following chart shows the annual
returns of the Portfolio* over the past four calendar years prior to the date of
this prospectus. Sales charges or other expenses at the contract level are not
reflected in this chart. If sales charges or other expenses at the contract
level had been included, the returns shown below would have been lower. Remember
that the past performance of the Portfolio is not indicative of its future
performance.

                              RISK/RETURN SUMMARY

                              INVESTMENT OBJECTIVE

The Strategic Stock Portfolio is a mutual fund with an investment objective to
seek an above average total return through a combination of potential capital
appreciation and dividend income, consistent with the preservation of invested
capital. There can be no assurance that the Portfolio will achieve its
investment objective.

                             INVESTMENT STRATEGIES

Under normal market conditions, the Portfolio's management seeks to achieve the
investment objective by investing in a portfolio of high dividend yielding
equity securities of companies included in the Dow Jones Industrial Average (the
"DJIA") or in the Morgan Stanley Capital International USA Index (the "MSCI USA
Index"). The Portfolio's investment adviser buys and sells investment securities
based primarily upon specific objective criteria (emphasizing dividend yield)
applied to DJIA and MSCI USA Index companies. The Portfolio may invest in
certain derivatives, such as options and futures, which may subject the
Portfolio to additional risks.

                                INVESTMENT RISKS

An investment in the Portfolio is subject to investment risks, and you could
lose money on your investment in the Portfolio.

MARKET RISK. Market risk is the possibility that the market values of securities
owned by the Portfolio will decline. Market risk may affect a single issuer,
industry, sector of the economy, or the market as a whole. Investments in equity
securities generally are affected by changes in the stock markets, which
fluctuate substantially over time, sometimes suddenly and sharply. The Portfolio
emphasizes high dividend yielding stocks selected based upon specific objective
criteria. The market value of the Portfolio's equity securities may or may not
fluctuate in tandem with overall changes in the stock markets. The ability of
the Portfolio's investment holdings to generate income is dependent on the
earnings and the continuing declaration of dividends by the issuers of such
securities.

RISKS OF USING DERIVATIVE INVESTMENTS. In general terms, a derivative investment
is one whose value depends on (or is derived from) the value of an underlying
asset, interest rate or index. Options and futures are examples of derivatives.
Such transactions involve risks different from the direct investment in
underlying securities such as imperfect correlation between the value of the
instruments and the underlying assets; risks of default by the other party to
certain transactions; risks that the transactions may result in losses that
partially or completely offset gains in portfolio positions; risks that the
transactions may not be liquid; and manager risk.

STYLE RISK. Securities are purchased and sold for the Portfolio based primarily
upon specific objective criteria. The Portfolio's style may not be as successful
in selecting the best-performing securities as other styles and may underperform
the overall market.

An investment in the Portfolio is not a deposit of any bank or other insured
depository institution. Your investment is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency.

                                INVESTOR PROFILE

In light of its objective and investment strategies, the Portfolio may be
appropriate for investors who:

- - Seek an above average total return through a combination of potential capital

should consider their long-term investment goals and financial needs when making

                                INVESTMENT TRUST
                              GENERAL INFORMATION


Van Kampen Life Investment Trust (the "Trust") is a diversified, open-end
management investment company which offers shares in eleven separate Portfolios
(the "Portfolios"). Each Portfolio is in effect a separate mutual fund. Each
Portfolio has its own income, expenses, assets, liabilities and net asset value
and each Portfolio issues its own shares.



Shares of each Portfolio represent an interest only in that Portfolio. Each
Portfolio offers two classes of shares - designated as Class I Shares and Class
II Shares. The Class II shares of each Portfolio are offered by this prospectus
(and the Class I Shares of each Portfolio are offered through a separate
prospectus). Shares are sold only to separate accounts (the "Accounts") of
various insurance companies to fund the benefits of variable annuity or variable
life insurance policies (the "Contracts"). The Accounts may invest in shares of
the Portfolios in accordance with allocation instructions received from contract
owners ("Contract Owners"). Such allocation rights, as well as sales charges and
other expenses imposed on Contract Owners by the Contracts, are further
described in the accompanying Contract prospectus.


Each Portfolio of the Trust has a different investment objective(s) which it
pursues through its investment policies as described below under "Investment
Objectives and Policies." The section entitled "Investment Practices" provides
further discussion of certain investment techniques, strategies or risks that
are common to some or all of the Portfolios. The investment objective(s) of each
Portfolio, except the Morgan Stanley Real Estate Securities Portfolio, is a
fundamental policy and may not be changed without shareholder approval of the
holders of a majority of the Portfolio's outstanding voting securities, as
defined in the Investment Company Act of 1940, as amended (the "1940 Act"). With
respect to the Morgan Stanley Real Estate Securities Portfolio, the investment
objectives may be changed by the Board of Trustees without shareholder approval,
but no change is anticipated. If there is a change in the objectives of such
Portfolio, shareholders should consider whether the Portfolio remains an
appropriate investment in light of their then current financial position and
needs. The differences in objectives and policies among the Portfolios can be
expected to affect the return of each Portfolio and the degree and types of
risks to which each Portfolio is subject. There are risks inherent in all
investments in securities; accordingly there can be no assurance that any
Portfolio will achieve its investment objective(s).

                             INVESTMENT OBJECTIVES
                                  AND POLICIES

                           ASSET ALLOCATION PORTFOLIO

The investment objective of the Asset Allocation Portfolio is to seek a high
total investment return consistent with prudent investment risk through a fully
managed investment policy utilizing equity securities as well as investment
grade intermediate-and long-term debt securities and money market securities.
Total investment return consists of current income (including dividends,
interest and discount accrual) and capital appreciation or depreciation. There
are risks inherent in all investments in securities; accordingly, there can be
no assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing in a portfolio of equity
securities, investment grade intermediate- and long-term debt securities,
including preferred stocks, convertible preferred stocks and convertible debt
securities, and money market securities. The Portfolio's investment adviser may
vary the composition of the Portfolio from time to time based upon its
evaluation of economic and market trends and the anticipated relative total
investment return available from a particular type of security. Accordingly, the
Portfolio may, at any given time, be substantially invested in equity
securities, debt securities or money market securities. Achieving the
Portfolio's investment objective depends on the investment adviser's ability to
assess the effect of economic and market trends on different sectors of the
market.

Common stocks are equity securities of a corporation or other entity that
entitle the holder to a pro rata share of the profits of a corporation, if any,
without preference over any other class of securities, including such entity's
debt securities, preferred stock or other senior equity security. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so. The common stocks in which the Portfolio invests will be primarily those
of large capitalization companies with characteristics including

                                       30
<PAGE>   110

a strong balance sheet, good financial resources, a satisfactory rate of return
on capital, a good industry position and superior management skills. The
Portfolio's investment adviser believes that companies that conform most closely
to these characteristics often tend to exhibit generally consistent earnings
growth. Among the types of securities in which the Portfolio may invest, the
investments in common stocks generally exhibit the greatest market risk, which
at times can substantially impact the market value of the Portfolio, sometimes
suddenly and sharply.

The Portfolio may invest in intermediate- and long-term debt securities
(including preferred stock, convertible preferred stock and convertible debt
securities) which are rated at the time of purchase BBB or better by Standard &
Poor's ("S&P") or rated Baa or better by Moody's Investors Service, Inc.
("Moody's") or unrated securities determined by the Portfolio's investment
adviser to be of comparable quality at the time of purchase. To the extent
investments are made in fixed-income securities, the Portfolio will invest
primarily in such securities which are rated A or better by either rating
agency. A more complete description of security ratings is contained in the
appendix to this prospectus. The market prices of debt securities generally vary
inversely with changes in prevailing interest rates and generally vary more for
debt securities with longer maturities. The Portfolio is not limited as to the
maturities of the debt securities it may purchase and the debt securities in
which the Portfolio intends to invest are those with intermediate- or
longer-maturities. Debt securities with longer maturities generally tend to
produce higher yields but are subject to greater price fluctuation as a result
of changes in interest rates than debt securities with shorter maturities.

Preferred stock generally has a preference as to dividends and liquidation over
an issuer's common stock but ranks junior to debt securities in an issuer's
capital structure. Unlike interest payments on debt securities, preferred stock
dividends are payable only if declared by the issuer's board of directors.
Preferred stock also may be subject to optional or mandatory redemption
provisions.

A convertible security is a bond, debenture, note, preferred stock, warrant or
other security that may be converted into or exchanged for a prescribed amount
of common stock or other equity security of the same or a different issuer
within a particular period of time at a specified price or formula. A
convertible security generally entitles the holder to receive interest paid or
accrued on debt securities or the dividend paid on preferred stock until the
convertible security matures or is redeemed, converted or exchanged. Before
conversion, convertible securities generally have characteristics similar to
both debt and equity securities. The value of convertible securities tends to
decline as interest rates rise and, because of the conversion feature, tends to
vary with fluctuations in the market value of the underlying equity security.
Convertible securities ordinarily provide a stream of income with generally
higher yields than those of common stocks of the same or similar issuers.
Convertible securities generally rank senior to common stock in a corporation's
capital structure but are usually subordinated to comparable nonconvertible
securities. Convertible securities generally do not participate directly in any
dividend increases or decreases of the underlying equity security although the
market prices of convertible securities may be affected by any such dividend
changes or other changes in the underlying equity security.

The Portfolio may invest money market securities including securities issued or
guaranteed by the U.S. government, its agencies or its instrumentalities, prime
commercial paper, certificates of deposit, bankers' acceptances or other
obligations of certain domestic banks and repurchase agreements. Money market
securities generally have low market risk and credit risk but also generally
have a low potential for total investment return.

The Portfolio may invest up to 25% of its total assets, based on market value at
the time of each investment, in securities of foreign issuers. Such investments
include certain risks not typically associated with investments in U.S.
securities. See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures contracts which may
subject the Portfolio to additional risks. See "Investment Practices -- Using
Options, Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

Because of the fully managed approach of the Portfolio, the Portfolio's turnover
rate may be greater than other

                                       31
<PAGE>   111

portfolios and result in increased transaction costs, including higher brokerage
charges, which may adversely impact the Portfolio's performance.

                               COMSTOCK PORTFOLIO

The investment objective of the Comstock Portfolio is to seek capital growth and
income through investments in equity securities, including common stocks,
preferred stocks and securities convertible into common and preferred stocks.
There are risks inherent in all investments in securities; accordingly, there
can be no assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing in equity securities, consisting
principally of common stocks. Common stocks are shares of a corporation or other
entity that entitle the holder to a pro rata share of the profits of the
corporation, if any, without preference over any other class of securities,
including such entity's debt securities, preferred stock and other senior equity
securities. Common stock usually carries with it the right to vote and
frequently an exclusive right to do so.

While the Portfolio invests principally in common stocks, the Portfolio may
invest in preferred stock and securities convertible into common and preferred
stocks. Preferred stock generally has a preference as to dividends and
liquidation over an issuer's common stock but ranks junior to debt securities in
an issuer's capital structure. Unlike interest payments on debt securities,
preferred stock dividends are payable only if declared by the issuer's board of
directors. Preferred stock also may be subject to optional or mandatory
redemption provisions. A convertible security is a bond, debenture, note,
preferred stock, warrant or other security that may be converted into or
exchanged for a prescribed amount of common stock or other equity security of
the same or a different issuer within a particular period of time at a specified
price or formula. A convertible security generally entitles the holder to
receive interest paid or accrued on debt securities or the dividend paid on
preferred stock until the convertible security matures or is redeemed, converted
or exchanged. Before conversion, convertible securities generally have
characteristics similar to both debt and equity securities. The value of
convertible securities tends to decline as interest rates rise and, because of
the conversion feature, tends to vary with fluctuations in the market value of
the underlying equity security. Convertible securities ordinarily provide a
stream of income with generally higher yields than those of common stock of the
same or similar issuers. Convertible securities generally rank senior to common
stock in a corporation's capital structure but are usually subordinated to
comparable nonconvertible securities. Preferred stocks and convertible
securities generally do not participate directly in any dividend increases or
decreases of the underlying equity security although the market prices of
preferred stocks and convertible securities may be affected by any such dividend
changes or other changes in the underlying equity security.

In selecting securities for investment, the Portfolio will focus primarily on
the security's potential for capital growth and income. The Portfolio emphasizes
a "value" style of investing seeking well-established, undervalued companies.
The Portfolio's investment adviser generally seeks to identify companies that
are undervalued and have identifiable factors that might lead to improved
valuations. This catalyst could come from within the company in the form of new
management, operational enhancements, restructurings or reorganization. It could
also be an external factor, such as an improvement in industry conditions or a
regulatory change. The Portfolio's style presents the risk that the valuations
never improve or that the returns on "value" equity securities are less than
returns on other styles of investing or the overall stock market. The Portfolio
may invest in issuers of small-, medium- or large-capitalization companies. The
securities of small- or medium-sized companies may be subject to more abrupt or
erratic market movements than securities of larger companies or the market
averages in general. In addition, such companies typically are subject to a
greater degree of change in earnings and business prospects than are larger
companies. Thus, the Portfolio may be subject to greater investment risk than
that assumed through investment in the equity securities of larger-
capitalization companies.

The Portfolio may dispose of a security whenever, in the opinion of the
Portfolio's investment adviser, factors indicate it is desirable to do so. Such
factors include change in economic or market factors in general or with respect
to a particular industry, a change in the market trend or other factors
affecting an individual security, changes in the relative market performance or
appreciation possibilities offered by individual securities and other
circumstances bearing on the desirability of a given investment.

                                       32
<PAGE>   112

The Portfolio generally holds up to 10% of its total assets in high-quality
short-term debt securities and in investment grade corporate debt securities in
order to provide liquidity. High-quality short-term debt investments include
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities, prime commercial paper, certificates of deposit, bankers'
acceptances and other obligations of domestic banks having total assets of at
least $500 million and repurchase agreements. Investment grade corporate debt
securities include securities rated BBB or better by Standard & Poor's ("S&P")
or rated Baa or better by Moody's Investors Service, Inc. ("Moody's") or unrated
securities judged by the investment adviser to be of comparable quality. A more
complete description of security ratings is contained in the appendix to this
prospectus. The market prices of such debt securities generally vary inversely
with changes in prevailing interest rates.

The Portfolio may invest up to 15% of its total assets in securities of foreign
issuers. Such investments include certain risks not typically associated with
investments in U.S. securities. See "Investment Practices -- Foreign
Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                           DOMESTIC INCOME PORTFOLIO

The primary investment objective of the Domestic Income Portfolio is to seek
current income. When consistent with the primary investment objective, capital
appreciation is a secondary investment objective. There are risks inherent in
all investments in securities; accordingly, there can be no assurance that the
Portfolio will achieve its investment objectives.

The Portfolio's investment adviser seeks to achieve these investment objectives
by investing primarily in a diversified portfolio of income securities,
including convertible and non-convertible debt securities and preferred stocks.
The Portfolio may invest in investment grade securities and lower-rated and
unrated securities. Under normal market conditions, the Portfolio invests at
least 80% of its total assets in income securities rated at the time of purchase
B or higher by S&P or rated B or higher by Moody's or unrated securities judged
by the Portfolio's investments adviser to be of comparable quality. Securities
rated BB or below by S&P or Ba or below by Moody's or unrated securities of
comparable quality are commonly referred to as "junk bonds" and involve special
risks as compared to investments in higher-grade securities. See "Risks of Lower
Grade Securities" below.

In general, the prices of income securities vary inversely with interest rates.
If interest rates rise, income security prices generally fall; if interest rates
fall, income security prices generally rise. In general, longer-maturity income
securities offer higher yields than shorter-maturity income securities, all
other factors, including credit quality, being equal; however, for a given
change in interest rates, longer-maturity income securities generally fluctuate
more in price (gaining or losing more in value) than shorter-maturity income
securities. While the Portfolio has no policy limiting the maturities of the
income securities in which it may invest, the Portfolio's investment adviser
seeks to moderate market risk by generally maintaining a portfolio duration
within a range of four to six years. Duration is a measure of the expected life
of an income security that was developed as an alternative to the concept of
"term to maturity." Duration incorporates an income security's yield, coupon
interest payments, final maturity and call features into one measure. A duration
calculation looks at the present value of a security's entire payment stream
whereas term to maturity is based solely on the date of a security's final
principal repayment.

The higher yields sought by the Portfolio are generally obtainable from
securities rated in the lower categories by recognized rating services or
unrated securities of comparable quality. These securities may be issued in
connection with corporate restructurings, such as leveraged buyouts, mergers,
acquisitions, debt recapitalization or similar events. These securities are
often issued by smaller, less creditworthy companies or companies with
substantial debt and may include financially troubled companies or companies in
default or in restructuring. Lower-grade securities often are subordinated to
the prior claims of banks and other senior lenders. Lower-grade securities are
regarded by the rating agencies as predominately speculative with respect to

                                       33
<PAGE>   113

the issuer's continuing ability to make principal and interest payments. The
ratings of S&P and Moody's represent their opinions of the quality of the
securities they undertake to rate, but not the market risk of such securities.
It should be emphasized, however, that ratings are general and are not absolute
standards of quality. Consequently, securities with the same maturity, coupon
and rating may have different yields while securities of the same maturity and
coupon with different ratings may have the same yield. See "Risks of Lower-Grade
Securities" below.

In purchasing securities for the Portfolio, the investment adviser considers,
among other thing, the security's current income potential, the rating assigned
to the security, the issuer's experience and managerial strength, the financial
soundness of the issuer and the outlook of its industry, changing financial
condition, borrowing requirements or debt maturity schedules, regulatory
concerns, and responsiveness to changes in business conditions and interest
rates. The Portfolio's investment adviser also may consider relative values
based on anticipated cash flow, interest or dividend coverage, balance sheet
analysis, and earnings prospects. The investment adviser evaluates each
individual income security for credit quality and value and attempts to identify
higher-yielding securities of companies whose financial condition has improved
since the issuance of such securities or is anticipated to improve in the
future. Because of the number of investment considerations involved in investing
in medium- and lower-grade securities, achievement of the Portfolio's investment
objectives may be more dependent upon the investment adviser's credit analysis
than is the case with investing solely in higher-grade securities.

The Portfolio may invest in securities not producing immediate cash income when
their effective yield over comparable instruments producing cash income make
these investments attractive. Prices on non-cash-paying instruments may be more
sensitive to changes in the issuer's financial condition, fluctuation in
interest rates and market demand/supply imbalances than cash-paying securities
with similar credit ratings, and thus may be more speculative. In addition, the
accrued interest income earned on such instruments is included in investment
company taxable income, thereby increasing the required minimum distributions to
shareholders without providing the corresponding cash flow with which to pay
such distributions. The Portfolio's investment adviser will weigh these concerns
against the expected total returns from such instruments.

The Portfolio also may purchase or sell U.S. government securities on a forward
commitment basis. See "When-Issued and Delayed Delivery" below.

Although the Portfolio invests primarily in domestic income securities, the
Portfolio may invest up to 25% of its total assets based on the market value at
the time of investment in securities of foreign issuers. Such investments
include certain risks not typically associated with investments in U.S.
securities. See "Investment Practices -- Foreign Securities."

Income securities in which the Portfolio may invest include the following:

STRAIGHT INCOME SECURITIES. These include bonds and other debt obligations which
bear a fixed or variable rate of interest payable at regular intervals and have
a fixed or resettable maturity date, and preferred stock, which generally has a
fixed or variable dividend rate (and, unlike interest on debt securities, such
dividends must be declared by the issuer's board of directors before becoming
payable) and may be subject to optional or mandatory redemption provisions. The
particular terms of such securities vary and may include features such as call
provisions and sinking funds.

PAY-IN-KIND INCOME SECURITIES. These pay interest in additional income
securities rather than in cash.

ZERO-COUPON SECURITIES. These bear no interest obligation but are issued at a
discount from their value at maturity. When held to maturity, their entire
return equals the difference between their issue price and their maturity value.
Interest is however accrued by the Portfolio each day for accounting and federal
income tax purposes.

ZERO-FIXED-COUPON SECURITIES. These are zero-coupon securities which convert on
a specified date to interest-bearing income securities.

The Portfolio may invest in securities rated below B by both S&P and Moody's,
common stocks or other equity securities and income securities on which interest
or dividends are not being paid when such investments are consistent with the
Portfolio's investment objectives or are acquired as part of a unit consisting
of a combination of income or equity securities. The Portfolio will not purchase
any such securities which will cause more than 20% of its total assets to be so
invested or which would cause more than 10% of its total assets to be invested
in common

                                       34
<PAGE>   114

stocks or other equity securities. Equity securities as referred to herein do
not include preferred stocks (which the Portfolio considers income securities).
This limitation does not require the Portfolio to sell a portfolio security
because its rating has been changed.

Securities rated below B by both S&P and Moody's often include debt obligations
or other securities of companies that are financially troubled, in default or
are in bankruptcy or reorganization. Securities of such companies are usually
available at a deep discount from the face value of the instrument. The
Portfolio may invest in deep discount securities when the Portfolio's investment
adviser believes that existing factors are likely to restore the company to a
healthy financial condition. Such factors include a restructuring of debt,
management changes, existence of adequate assets, or other unusual
circumstances.

A security purchased at a deep discount may pay a very high effective yield. In
addition, if the financial condition of the issuer improves, the underlying
value of the security may increase, resulting in a capital gain. If the company
defaults on its obligations or remains in default, or if the plan of
reorganization is insufficient for debtholders, the deep discount securities may
stop generating income and lose value or become worthless. The Portfolio's
investment adviser will balance the benefits of deep discount securities with
their risks. While a diversified portfolio may reduce the overall impact of a
deep discount security that is in default or loses its value, the risk cannot be
eliminated.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

RISKS OF LOWER-GRADE SECURITIES. Securities which are in the lower-grade
categories generally offer a higher current yield than is offered by
higher-grade securities of similar maturities, but they also generally involve
greater risks, such as greater credit risk, greater market risk, greater
liquidity concerns and potentially greater manager risk. Investors should
carefully consider the risks of owning shares of a portfolio which invests in
lower-grade securities before investing in the Portfolio.

Credit risk relates to the issuer's ability to make timely payment of interest
and principal when due. Lower-grade securities are considered more susceptible
to nonpayment of interest and principal or default than higher-grade securities.
Increases in interest rates or changes in the economy may significantly affect
the ability of issuers of lower-grade debt securities to pay interest and to
repay principal, to meet projected financial goals or to obtain additional
financing. In the event that an issuer of securities held by the Portfolio
experiences difficulties in the timely payment of principal and interest and
such issuer seeks to restructure the terms of its borrowings, the Portfolio may
incur additional expenses and may determine to invest additional assets with
respect to such issuer or the project or projects to which the Portfolio's
securities relate. Further, the Portfolio may incur additional expenses to the
extent that it is required to seek recovery upon a default in the payment of
interest or the repayment of principal on its portfolio holdings, and the
Portfolio may be unable to obtain full recovery on such amounts.

Market risk relates to changes in market value of a security that occur as a
result of variation in the level of prevailing interest rates and yield
relationships in the debt securities market and as a result of real or perceived
changes in credit risk. The value of the Portfolio's investments can be expected
to fluctuate over time. When interest rates decline, the value of a portfolio
invested in fixed income securities generally can be expected to rise.
Conversely, when interest rates rise, the value of a portfolio invested in fixed
income securities generally can be expected to decline. However, the secondary
market prices of lower-grade debt securities generally are less sensitive to
changes in interest rate and are more sensitive to general adverse economic
changes or specific developments with respect to the particular issuers than are
the secondary market prices of higher-grade debt securities. A significant
increase in interest rates or a general economic downturn could severely disrupt
the market for lower-grade securities and adversely affect the market value of
such securities. Such events also could lead to a higher incidence of default by
issuers of lower-grade securities as compared with higher-grade securities. In
addition, changes in credit risks, interest rates, the credit markets or periods
of general economic uncertainty can be expected to result in increased
volatility in the market price of the lower-grade securities in the Portfolio
and thus in the net asset value of the Portfolio. Adverse publicity and investor
perceptions, whether or not based on rational analysis, may affect the value and
liquidity of lower-grade securities.

The markets for lower-grade securities may be less liquid than the markets for
higher-grade securities.

                                       35
<PAGE>   115

Liquidity relates to the ability of a fund to sell a security in a timely manner
at a price which reflects the value of that security. To the extent that there
is no established retail market for some of the lower-grade securities in which
the Portfolio may invest, trading in such securities may be relatively inactive.
Prices of lower-grade securities may decline rapidly in the event a significant
number of holders decide to sell. Changes in expectations regarding an
individual issuer or lower-grade securities generally could reduce market
liquidity for such securities and make their sale by the Portfolio more
difficult, at least in the absence of price concessions. The effects of adverse
publicity and investor perceptions may be more pronounced for securities for
which no established retail market exists as compared with the effects on
securities for which such a market does exist. An economic downturn or an
increase in interest rates could severely disrupt the market for such securities
and adversely affect the value of outstanding securities or the ability of the
issuers to repay principal and interest. Further, the Portfolio may have more
difficulty selling such securities in a timely manner and at their stated value
than would be the case for securities for which an established retail market
does exist.

The Portfolio's investment adviser is responsible for determining the net asset
value of the Portfolio, subject to the supervision of the Portfolio's Board of
Trustees. During periods of reduced market liquidity and in the absence of
readily available market quotations for lower-grade securities held in the
Portfolio's portfolio, the ability of the Portfolio's investment adviser to
value the Portfolio's securities becomes more difficult and the investment
adviser's use of judgment may play a greater role in the valuation of the
Portfolio's securities due to the reduced availability of reliable objective
data.

New or proposed laws may have an impact on the market for lower-grade
securities. The Portfolio's investment adviser is unable at this time to predict
what effect, if any, legislation may have on the market for lower-grade
securities.

Special tax considerations are associated with investing in certain lower-grade
securities, such as zero coupon or pay-in-kind securities. The Portfolio accrues
income on these securities prior to the receipt of cash payments. The Portfolio
must distribute substantially all of its income to its shareholders to qualify
for pass-through treatment under federal income tax law and may, therefore, have
to dispose of its portfolio securities to satisfy distribution requirements.

The Portfolio will rely on its investment adviser's judgment, analysis and
experience in evaluating the creditworthiness of an issue. The amount of
available information about the financial condition of certain lower-grade
issuers may be less extensive than other issuers. In its analysis, the
Portfolio's investment adviser may consider the credit ratings of S&P and
Moody's in evaluating securities although the investment adviser does not rely
primarily on these ratings. Ratings evaluate only the safety of principal and
interest payments, not the market value risk. Additionally, ratings are general
and not absolute standards of quality, and credit ratings are subject to the
risk that the creditworthiness of an issuer may change and the rating agencies
may fail to change such ratings in a timely fashion. A rating downgrade does not
require the Portfolio to dispose of a security. The Portfolio's investment
adviser continuously monitors the issuers of securities held in the Portfolio.
Because of the number of investment considerations involved in investing in
lower-grade securities, achievement of the Portfolio's investment objectives may
be more dependent upon the investment adviser's credit analysis than is the case
with investing in higher-grade securities.


The table below sets forth the percentages of the Portfolio's assets invested
during the fiscal year ended December 31, 1999 in the various S&P's and Moody's
rating categories and in unrated securities determined by the Portfolio's
investment adviser to be of comparable quality. The percentages are based on the
dollar-weighted average of credit ratings of all securities held by the
Portfolio during the 1999 fiscal year computed on a monthly basis.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase or sell
U.S. government securities on a "when-issued" or "delayed delivery" basis
("Forward Commitments"). These transactions occur when securities are purchased
or sold by the Portfolio with payment and delivery taking place in the future,
frequently a month or more after such transaction. The price is fixed on the
date of the commitment, and the seller continues to accrue interest on the
securities covered by the Forward Commitment until delivery and payment take
place. At the time of settlement, the market value of the securities may be more
or less than the purchase or sale price. The Portfolio may either settle a
Forward Commitment by taking delivery of the securities or may either resell or
repurchase a Forward Commitment on or before the settlement date in which event
the Portfolio may reinvest the proceeds in another Forward Commitment. These
transactions are subject to market risk as the value or yield of a security at
delivery may be more or less than the purchase price or the yield generally
available on securities when delivery occurs. When engaging in Forward
Commitments, the Portfolio relies on the other party to complete the
transaction, should the other party fail to do so, the Portfolio might lose a
purchase or sale opportunity that could be more advantageous than alternative
opportunities at the time of the failure. The Portfolio maintains a segregated
account (which is marked to market daily) of cash or liquid portfolio securities
with the Portfolio's custodian in an aggregate amount equal to the amount of its
commitment as long as the obligation to purchase or sell continues.

                           EMERGING GROWTH PORTFOLIO


The investment objective of the Emerging Growth Portfolio is to seek capital
appreciation. Any ordinary income received from securities owned by the
Portfolio is entirely incidental to the Portfolio's investment objective of
capital appreciation. There are risks inherent in all investments in securities;
accordingly, there can be no assurance that the Portfolio will achieve its
investment objective.



Under normal conditions, the Portfolio's investment adviser seeks to achieve the
Portfolio's investment objective by investing at least 65% of the Portfolio's
total assets in common stocks of emerging growth companies. Emerging growth
companies are those companies in the early stages of their life cycles that the
Portfolio's investment adviser believes have the potential to become major
enterprises. Investments in such companies may offer greater opportunities for
growth of capital than larger, more established companies, but also may involve
certain special risks. Emerging growth companies often have limited product
lines, markets, distribution channels or financial resources, and they may be
dependent upon one or a few key people for management. The securities of such
companies may be subject to more abrupt or erratic market movements than
securities of larger, more established companies or the market averages in
general.


The Portfolio does not limit its investments to any single group or type of
security. The Portfolio may invest in securities involving special situations,
such as new management, special products and techniques, unusual developments,
mergers or liquidations. Investments in unseasoned companies and special
situations often involve much greater risks than are inherent in other types of
investments, because securities of such companies may be more likely to
experience unexpected fluctuations in price.

The Portfolio's primary approach is to seek what the Portfolio's investment
adviser believes to be unusually attractive growth investments on an individual
company basis. The Portfolio may invest in securities that have above average
volatility of price movement. Because prices of common stocks and other
securities fluctuate, the value of an investment in the Portfolio will vary
based upon the Portfolio's investment performance. The Portfolio attempts to
reduce overall exposure to risk from declines in securities prices by spreading
its investments over many different companies in a variety of industries. There
is, however, no assurance that the Portfolio will be successful in achieving its
objective.

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so.

While the Portfolio invests principally in common stocks, the Portfolio may
invest to a limited extent in other securities such as preferred stocks,
convertible securities and warrants. Preferred stock generally has a preference
as to dividends and liquidation over an issuer's common stock but ranks junior
to debt securities in an issuer's capital structure. Unlike

                                       37
<PAGE>   117

interest payments on debt securities, preferred stock dividends are payable only
if declared by the issuer's board of directors. Preferred stock also may be
subject to optional or mandatory redemption provisions. Generally, warrants are
securities that may be exchanged for a prescribed amount of common stock or
other equity security of the issuer within a particular period of time at a
specified price or in accordance with a specified formula.

The Portfolio may invest up to 20% of its total assets in securities of foreign
issuers. Such investments include certain risks not typically associated with
investments in U.S. securities. See "Investment Practices -- Foreign
Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and related options which may subject the
Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                              ENTERPRISE PORTFOLIO

The investment objective of the Enterprise Portfolio is to seek capital
appreciation through investments in securities believed by the Portfolio's
investment adviser to have above average potential for capital appreciation. Any
income received on securities owned by the Portfolio is entirely incidental to
the Portfolio's investment objective of capital appreciation. There are risks
inherent in all investments in securities; accordingly, there can be no
assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing primarily in common stocks which
it believes have above-average potential for capital appreciation. The
Portfolio's primary approach is to seek what the Portfolio's investment adviser
believes to be unusually attractive growth investments on an individual company
basis. The Portfolio may invest in securities that have above average volatility
of price movement. Because prices of common stocks and other securities
fluctuate, the value of an investment in the Portfolio will vary. The Portfolio
attempts to reduce overall exposure to risk from declines in securities prices
by spreading its investments over many different companies in a variety of
industries.

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so.

While the Portfolio invests principally in common stocks, the Portfolio may
invest in preferred stocks and warrants. Preferred stock generally has a
preference as to dividends and liquidation over an issuer's common stock but
ranks junior to debt securities in an issuer's capital structure. Unlike
interest payments on debt securities, preferred stock dividends are payable only
if declared by the issuer's board of directors. Preferred stock also may be
subject to optional mandatory redemption provisions. Generally, warrants are
securities that may be exchanged for a prescribed amount of common stock or
other equity security of the issuer within a particular period of time at a
specified price or in accordance with a specific formula.

In selecting securities for investment, the Portfolio will generally focus on
common stocks of "growth" companies, including companies with new products,
services or processes. The investment adviser seeks such securities which it
believes offer a combination of strong business fundamentals at an attractive
price. Growth companies generally include those companies with established
records of growth in sales or earnings that the Portfolio's investment adviser
believes are entering into a growth cycle in their respective businesses, with
the expectation that the stock of such companies will increase in value. Stocks
of different types, such as "growth" stocks or "value" stocks, tend to shift in
and out of favor depending on market and economic conditions. Thus, the value of
the Portfolio's investments in "growth" stocks will vary and may at times be
lower or higher than that of other types of funds. The market values of "growth"
common stocks may be more volatile than other types of investments. The
Portfolio may invest in companies generating or applying new technologies, new
or improved distribution techniques or new services, which companies may benefit
from changing consumer demands or lifestyles, or companies that have projected
earnings in excess of the average for their sector or industry. In each case,

                                       38
<PAGE>   118

such companies have prospects that the Portfolio's investment adviser believes
are favorable for above-average capital appreciation. The Portfolio also may
focus its investments on stocks of companies in cyclical industries during
periods when their securities appear attractive for capital appreciation.

The companies in which the Portfolio invests may be in any market capitalization
range, provided the Portfolio's investment adviser believes the investment is
consistent with the Portfolio's objective. The securities of small- or
medium-sized companies may be subject to more abrupt or erratic market movements
than securities of larger companies or the market averages in general. In
addition, such companies typically are subject to a greater degree of change in
earnings and business prospects than are larger companies. Thus, to the extent
the Portfolio invests in small- and medium-sized companies, the Portfolio may be
subject to greater investment risk than that assumed through investment in the
equity securities of larger-capitalization companies.

The Portfolio may dispose of a security whenever, in the opinion of the
Portfolio's investment adviser, factors indicate it is desirable to do so. Such
factors include change in economic or market factors in general or with respect
to a particular industry, a change in the market trend or other factors
affecting an individual security, changes in the relative market performance or
appreciation possibilities offered by individual securities and other
circumstances bearing on the desirability of a given investment.

The Portfolio generally holds a portion of its assets in investment grade
short-term debt securities and in investment grade corporate debt securities in
order to provide liquidity. Investment grade short-term debt investments include
securities issued or guaranteed by the U.S. government, its agencies or its
instrumentalities, prime commercial paper, certificates of deposit, bankers'
acceptances and other obligations of domestic banks having total assets of at
least $500 million and repurchase agreements. Investment grade corporate debt
securities include securities rated BBB or better by Standard & Poor's ("S&P")
or Baa or higher by Moody's Investors Service, Inc. ("Moody's"). A more complete
description of security ratings is contained in the appendix to this prospectus.
The market prices of such debt securities generally vary inversely with changes
in prevailing interest rates.

The Portfolio may invest up to 10% of its total assets, based on market value at
the time of each investment, in securities of foreign issuers. Such investments
include certain risks not typically associated with investments in U.S.
securities. See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                            GLOBAL EQUITY PORTFOLIO

The investment objective of the Global Equity Portfolio is to seek long-term
growth of capital through investments in an internationally diversified
portfolio of equity securities of companies of any nation including the United
States. There are risks inherent in all investments in securities; accordingly,
there can be no assurance that the Portfolio will achieve its investment
objective.

The Portfolio's investment adviser seeks to achieve the investment objective by
investing in an internationally diversified portfolio of equity securities,
including common stocks, preferred stocks and warrants or options to acquire
such securities, based upon the evaluation by the Portfolio's investment adviser
of economic and market trends and the anticipated relative capital growth
opportunities available from a particular country or security. Under normal
market conditions, the Portfolio invests at least 65% of its total assets in
securities of issuers of at least three countries (including the United States.)

The Portfolio's investment adviser, subject to the direction of the Portfolio's
Board of Trustees, provides the Portfolio with an overall investment program
consistent with the Portfolio's objective and policies. The Portfolio's
investments may be shifted among the world's various capital markets, including
developed and undeveloped countries, and among different types of securities in
accordance with the investment adviser's ongoing analysis of economic or market
trends, developments affecting the markets and securities in which the Portfolio
may invest and

                                       39
<PAGE>   119

the anticipated relative capital growth opportunities available from a
particular country or security.

In selecting non-U.S. investments for the Portfolio, the Portfolio's investment
adviser uses a "top-down" approach that emphasizes country and sector selection
and weighting rather than individual security selection. This approach reflects
the investment adviser's philosophy for this Portfolio that a broad selection of
securities representing exposure to world markets based upon the economic
outlook and current valuation levels for each country and certain sectors is an
effective way to maximize the return and minimize the risk associated with
global investment.

The Portfolio's investment adviser determines country and sector allocations for
the Portfolio on an ongoing basis. The Portfolio will invest in the United
States and other industrialized countries throughout the world that comprise the
Morgan Stanley Capital International World Index. In addition, the Portfolio may
invest a portion of its assets in securities of certain developing or emerging
markets countries.

By analyzing a variety of macroeconomic and political factors, the Portfolio's
investment adviser develops fundamental projections on interest rates,
currencies, corporate profits and economic growth for each country or sector.
These country projections are then used to determine what the investment adviser
believes to be a fair value for the stock market of each country or sector.
Discrepancies between actual value and fair value, as determined by the
investment adviser, provide an expected return for each stock market. The
expected return is adjusted by currency return expectations derived from the
investment adviser's purchasing-power parity exchange rate model to arrive at an
expected total return in U.S. dollars. The final country and sector allocation
decision is then reached by considering the expected total return in light of
various considerations such as market size, volatility, liquidity and country
risk.

Within a particular country or sector, investments are made through the purchase
of equity securities which, in the aggregate, replicate a broad market index for
that country or sector, which in most cases will be the Morgan Stanley Capital
International Index ("MSCI Index") for the particular country or sector. The
MSCI Indices measure the performance of stock markets worldwide and are based on
the share prices of companies listed on the local stock exchange of the
specified country or countries within a specified region. The combined market
capitalization of companies in these indices represent approximately 60% of the
aggregate market value of the covered stock exchanges. Companies included in the
MSCI Index for a country replicate the industry composition of the local market
and are a representative sampling of large-, medium- and small-companies,
subject to liquidity. Non-domiciled companies traded on the country's local
exchange and companies with restricted float due to dominant shareholders or
cross-ownership are avoided. The Portfolio's investment adviser may overweight
or underweight an industry segment of a particular index if it concludes this
would be advantageous to the Portfolio.

The Portfolio may invest in equity securities including common stocks, preferred
stocks, warrants or options to acquire such securities and depository receipts.
Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so. Preferred stock generally has a preference as to dividends and
liquidation over an issuer's common stock but ranks junior to debt securities in
an issuer's capital structure. Unlike interest payments on debt securities,
preferred stock dividends are payable only if declared by the issuer's board of
directors. Preferred stock also may be subject to optional or mandatory
redemption provisions. Generally, warrants or options to acquire equity
securities are securities that may be exchanged for a prescribed amount of such
equity securities of the issuer within a particular period of time at a
specified price or in accordance with a specified formula.

The Portfolio may invest in issuers of small-, medium- or large-capitalization
companies. The securities of small- or medium-sized companies may be subject to
more abrupt or erratic market movements than securities of larger companies or
the market averages in general. In addition, such companies typically are
subject to a greater degree of change in earnings and business prospects than
are larger companies. Thus, to the extent the Portfolio invests in small- and
medium-sized companies, the Portfolio may be subject to greater investment risk
than that assumed through investment in the equity securities of
larger-capitalization companies.

                                       40
<PAGE>   120

The Portfolio may purchase foreign securities in the form of American Depositary
Receipts ("ADRs") and European Depositary Receipts ("EDRs") or other securities
representing underlying shares of foreign companies. These securities are not
necessarily denominated in the same currency as the underlying securities but
generally are denominated in the currency of the market in which they are
traded. ADRs are receipts typically issued by an American bank or trust company
which evidence ownership of underlying securities issued by foreign
corporations. ADRs are publicly traded on exchanges or over-the-counter in the
United States and are issued through "sponsored" or "unsponsored" arrangements.
In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay
some or all of the depositary's transaction fees, whereas under an unsponsored
arrangement, the foreign issuer assumes no obligations and the depositary's
transaction fees are paid by the ADR holders. In addition, less information
generally is available for an unsponsored ADR than a sponsored ADR, and
financial information about a company may not be as reliable for an unsponsored
ADR as it is for a sponsored ADR. The Portfolio may invest in ADRs through both
sponsored and unsponsored arrangements. EDRs are receipts issued in Europe by
banks or depositaries which evidence similar ownership arrangements.

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures contracts which may
subject the Portfolio to additional risks. See "Investment Practices -- Using
Options, Futures Contracts and Options in Futures Contracts."

The Portfolio generally holds a portion of its assets in short-term debt
securities in order to provide liquidity. Short-term debt securities include
securities issued or guaranteed by the U.S. government or foreign governments,
their agencies or instrumentalities, prime commercial paper, certificates of
deposit, bankers' acceptances and other obligations of banks having total assets
of at least $500 million and repurchase agreements.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

RISK FACTORS OF INVESTING IN SECURITIES OF FOREIGN ISSUERS. An investment in the
Portfolio involves risks similar to those of investing in foreign securities
generally. The Portfolio invests in securities denominated in U.S. dollars and
in currencies other than U.S. dollars. The percentage of assets invested in
securities of a particular country or denominated in a particular currency will
vary in accordance with the investment adviser's assessment of the relative
yield, growth potential and the relationship of a country's currency to the U.S.
dollar, which is based upon such factors as fundamental economic strength,
credit quality and interest rate trends. Investments in foreign securities
present certain risks not ordinarily associated with investments in securities
of U.S. issuers. These risks include fluctuations in foreign currency exchange
rates, political, economic or legal developments (including war or other
instability, expropriation of assets, nationalization and confiscatory
taxation), imposition of foreign exchange limitations (including currency
blockage), withholding taxes on dividend or interest payments or capital
transactions or other restrictions, higher transaction costs (including higher
brokerage, custodial and settlement costs and currency translation costs) and
possible difficulty in enforcing contractual obligations or taking judicial
action. Also, foreign securities may not be as liquid and may be more volatile
than comparable domestic securities.

In addition, there often is less publicly available information about many
foreign issuers, and issuers of foreign securities are subject to different,
often less comprehensive, auditing, accounting, financial reporting and
disclosure requirements than domestic issuers. There is generally less
government regulation of stock exchanges, brokers and listed companies abroad
than in the U.S., and, with respect to certain foreign countries, there is a
possibility of expropriation or confiscatory taxation, or diplomatic
developments which could affect investment in those countries. Because there is
usually less supervision and governmental regulation of exchanges, brokers and
dealers than there is in the U.S., the Portfolio may experience settlement
difficulties or delays not usually encountered in the U.S.

Delays in making trades in foreign securities relating to volume constraints,
limitations or restrictions, clearance or settlement procedures, or otherwise
could impact yields and result in temporary periods when assets are not fully
invested or attractive investment opportunities are foregone.

The Portfolio's investments in securities of developing or emerging markets are
subject to greater risks than the Portfolio's investments in securities of

                                       41
<PAGE>   121

developed countries since emerging markets tend to have economic structures that
are less diverse and mature and political systems that are less stable than
developed countries.

Since the Portfolio invests in securities denominated or quoted in currencies
other than the U.S. dollar, the Portfolio will be affected by changes in foreign
currency exchange rates (and exchange control regulations) which affect the
value of securities in the Portfolio and the income and appreciation or
depreciation of Portfolio investments. Changes in foreign currency exchange
ratios relative to the U.S. dollar will affect the U.S. dollar value of the
Portfolio's assets denominated in that currency and the Portfolio's yield on
such assets. In addition, the Portfolio will incur costs in connection with
conversions between various currencies. The Portfolio's foreign currency
exchange transactions generally will be conducted on a spot basis (that is, cash
basis) at the spot rate for purchasing or selling currency prevailing in the
foreign currency exchange market. The Portfolio purchases and sells foreign
currency on a spot basis in connection with the settlement of transactions in
securities traded in such foreign currency. The Portfolio does not purchase and
sell foreign currencies as an investment.

The Portfolio also may enter into contracts with banks or other foreign currency
brokers or dealers to purchase or sell foreign currencies at a future date
("forward contracts") and purchase and sell foreign currency futures contracts
to hedge against changes in foreign currency exchange rates. A foreign currency
forward contract is a negotiated agreement between the contracting parties to
exchange a specified amount of currency at a specified future time at a
specified rate. The rate can be higher or lower than the spot rate between the
currencies that are the subject of the contract.

The Portfolio may attempt to hedge against changes in the value of the U.S.
dollar in relation to a foreign currency by entering into a forward contract for
the purchase or sale of the amount of foreign currency invested or to be
invested, or by buying or selling a foreign currency futures contract for such
amount. Futures contracts are described below under the heading "Investment
Practices -- Using Options, Futures Contracts and Options in Futures Contracts."
Such hedging strategies may be employed before the Portfolio purchases a foreign
security traded in the hedged currency which the Portfolio anticipates acquiring
or between the date the foreign security is purchased or sold and the date on
which payment therefor is made or received. Hedging against a change in the
value of a foreign currency in the foregoing manner does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Furthermore, such hedging transactions reduce
or preclude the opportunity for gain if the value of the hedged currency should
move in the direction opposite to the hedged position. Unanticipated changes in
currency prices may result in poorer overall performance for the Portfolio than
if it had not entered into such contracts.

The Portfolio's custodian will place cash or liquid securities in a segregated
account having a value equal to the aggregate amount of the Portfolio's
commitments under forward contracts. If the value of the securities placed in
the segregated account declines, additional cash or securities are placed in the
account on a daily basis so that the value of the account equals the amount of
the Portfolio's commitments with respect to such contracts. As an alternative to
maintaining all or part of the segregated account, the Portfolio may purchase a
call option permitting the Portfolio to purchase the amount of foreign currency
by a forward sale contract at a price no higher than the forward contract price
or the Portfolio may purchase a put option permitting the Portfolio to sell the
amount of foreign currency subject to a forward purchase contract at a price as
high or higher than the forward contract price.

SHORT SALES The Portfolio may from time to time make short sales of securities
it owns or has the right to acquire through conversion or exchange of other
securities it owns. A short sale is "against the box" to the extent that the
Portfolio contemporaneously owns or has the right to obtain at no added cost
securities identical to those sold short. In a short sale, the Portfolio does
not immediately deliver the securities sold and does not receive the proceeds
from the sale. The Portfolio is required to recognize gain from the short sale
for federal income tax purposes at the time it enters into the short sale, even
though it does not receive the sales proceeds until it delivers the securities.
The Portfolio is said to have a short position in the securities sold until it
delivers the securities sold, at which time it receives the proceeds of the
sale. The Portfolio may not make short sales or maintain a short position if to
do so would cause more than 25% of its total assets, taken at market value, to
be held as collateral for such sales. To secure its obligation to deliver the
securities sold

                                       42
<PAGE>   122

short, the Portfolio will deposit in escrow in a separate account with its
custodian an equal amount of the securities sold short or securities convertible
into or exchangeable for such securities. The Portfolio may close out a short
position by purchasing and delivering an equal amount of the securities sold
short, rather than by delivering securities already held by the Portfolio,
because it may want to continue to receive interest and dividend payments on its
investments that are convertible into the securities sold short.

                              GOVERNMENT PORTFOLIO

The investment objective of the Government Portfolio is to seek to provide
investors with high current return consistent with preservation of capital.
There are risks inherent in all investments in securities; accordingly, there
can be no assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing at least 80% of the Portfolio's
total assets in debt securities issued or guaranteed by the U.S. government, its
agencies or its instrumentalities, including mortgage-related securities issued
or guaranteed by instrumentalities of the U.S. government. Under normal market
conditions, the Portfolio may invest up to 20% of its total assets in other
government-related securities, including privately issued mortgage-related and
mortgage-backed securities not issued or directly guaranteed by
instrumentalities of the U.S. government, privately issued certificates
representing "stripped" U.S. government or mortgage-related securities and
repurchase agreements fully collateralized by U.S. government securities. While
securities purchased for the Portfolio's investments may be issued or guaranteed
by the U.S. government, the shares issued by the Portfolio to investors are not
insured or guaranteed by the U.S. government, its agencies or its
instrumentalities or any other person or entity. For more information on the
Portfolio's investments, see "U.S. Government Securities" and "Government-
Related Securities" below.

The value of debt securities generally varies inversely with changes in
prevailing interest rates. If interest rates rise, debt security prices
generally fall; if interest rates fall, debt security prices generally rise.
Debt securities with longer maturities generally offer higher yields than debt
securities with shorter maturities assuming all other factors, including credit
quality, being equal. For a given change in interest rates, the market prices of
longer-maturity debt securities generally fluctuate more than the market prices
of shorter-maturity debt securities. While the Portfolio has no policy limiting
the maturities of the individual debt securities in which it may invest, the
Portfolio's investment adviser seeks to moderate market risk by generally
maintaining a portfolio duration of four to six years. Duration is a measure of
the expected life of a debt security that was developed as an alternative to the
concept of "term to maturity." Duration incorporates a debt security's yield,
coupon interest payments, final maturity and call features into one measure. A
duration calculation looks at the present value of a security's entire payment
stream whereas term to maturity is based solely on the date of a security's
final principal repayment.

The Portfolio may invest in mortgage-related or mortgage-backed securities. The
value of such securities tend to vary inversely with changes in prevailing
interest rates, but also are more susceptible to prepayment risk and extension
risk than other debt securities.

The Portfolio may purchase debt securities at a premium over the principal or
face value in order to obtain higher current income. The amount of any premium
declines during the term of the security to zero at maturity. Such decline
generally is reflected in the market price of the security and thus in the
Portfolio's net asset value. Any such decline is realized for accounting
purposes as a capital loss at maturity or upon resale. Prior to maturity or
resale, such decline in value could be offset, in whole or part, or increased by
changes in the value of the security due to changes in interest rate levels.

In order to hedge against changes in interest rates, the Portfolio may enter
into certain derivative transactions, such as the purchase or sell options,
futures contracts and options on such contracts and interest rate swaps or other
interest rate-related transactions. By using such strategies, the Portfolio
seeks to limit its exposure to adverse interest rate changes, but the Portfolio
also reduces its potential for capital appreciation on debt securities if
interest rates decline. The purchase and sale of such securities may result in a
higher portfolio turnover rate than if the Portfolio had not purchased or sold
such securities. See "Interest Rate Transactions" and "Investment Practices --
Using Options, Futures Contracts and Options on Futures Contracts."

                                       43
<PAGE>   123

The Portfolio also may purchase or sell U.S. government securities on a forward
commitment basis. See "When-Issued and Delayed Delivery Securities" below.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

The Portfolio intends to invest in U.S. Treasury securities and in securities
issued by at least four U.S. government agencies or instrumentalities in the
amounts necessary to permit the Accounts to meet certain diversification
requirements imposed by Section 817(h) of the Internal Revenue Code of 1986, as
amended (the "Code"), at the end of each quarter of the year (or within 30 days
thereafter). See "Dividends, Distributions and Taxes." In the event the
Portfolio does not meet the diversification requirements of Section 817(h) of
the Code, the policies funded by shares of the Portfolio will not be treated as
life insurance for federal income tax purposes and the owners of the policies
will be subject to taxation on their share of the dividends and distributions
paid by the Portfolio.

U.S. GOVERNMENT SECURITIES. Securities issued or guaranteed by the U.S.
government, its agencies or its instrumentalities include: (1) U.S. Treasury
obligations, which differ in their interest rates, maturities and times of
issuance: U.S. Treasury bills (maturity of one year or less), U.S. Treasury
notes (maturity of one to ten years), and U.S. Treasury bonds (generally
maturities of greater than ten years), including the principal components or the
interest components issued by the U.S. government under the Separate Trading of
Registered Interest and Principal Securities program (i.e. "STRIPS"), all of
which are backed by the full faith and credit of the U.S.; and (2) obligations
issued or guaranteed by U.S. government agencies or instrumentalities, including
government guaranteed mortgage-related securities, some of which are backed by
the full faith and credit of the U.S. Treasury, some of which are supported by
the right of the issuer to borrow from the U.S. government and some of which are
backed only by the credit of the issuer itself.

MORTGAGE-RELATED SECURITIES. Mortgage loans securing real property made by
banks, savings and loan institutions, and other lenders are often assembled into
pools. Interests in such pools may then be issued by private entities or also
may be issued or guaranteed by an agency or instrumentality of the U.S.
government. Interests in such pools are what this prospectus calls
"mortgage-related securities." Mortgage-related securities include, but are not
limited to, obligations issued or guaranteed by the Government National Mortgage
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC"). GNMA is a wholly owned
corporate instrumentality of the U.S. whose securities and guarantees are backed
by the full faith and credit of the U.S. FNMA, a federally chartered and
privately owned corporation, and FHLMC, a federal corporation, are
instrumentalities of the U.S. The securities and guarantees of FNMA and FHLMC
are not backed, directly or indirectly, by the full faith and credit of the U.S.
Although the Secretary of the Treasury of the U.S. has discretionary authority
to lend amounts to FNMA up to certain specified limits, neither the U.S.
government nor any agency thereof is obligated to finance FNMA's or FHLMC's
operations or to assist FNMA or FHLMC in any other manner. Securities of FNMA
and FHLMC include those issued in principal only or interest only components.

The yield and payment characteristics of mortgage-related securities differ from
traditional debt securities. Mortgage-related securities are characterized by
monthly payments to the holder, reflecting the monthly payments made by the
borrowers who received the underlying mortgage loans less fees paid to the
guarantor and the servicer of such mortgage loans. The payments to the holders
of mortgage-related securities (such as the Portfolio), like the payments on the
underlying mortgage loans, represent both principal and interest. Although the
underlying mortgage loans are for specified periods of time, such as 20 or 30
years, the borrowers can, and typically do, pay them off sooner. Thus, the
holders of mortgage-related securities frequently receive prepayments of
principal, in addition to the principal which is part of the regular monthly
payment. Faster or slower prepayments than expected on underlying mortgage loans
can dramatically alter the valuation and yield-to-maturity of mortgage-related
securities. The value of mortgage-related securities, like traditional debt
securities, tends to vary inversely with changes in prevailing interest rates.
Mortgage-related securities, however, may benefit less than traditional debt
securities from declining interest rates because a property owner is more likely
to refinance a mortgage which bears a relatively high rate of interest during a
period of declining interest rates. This means some of the Portfolio's higher
yielding securities might be converted to cash, and the Portfolio will be forced
to accept lower interest rates when that cash is used to purchase new securities
at prevailing interest rates. The

                                       44
<PAGE>   124

increased likelihood of prepayment when interest rates decline also limits
market price appreciation of mortgage-related securities. If the Portfolio buys
mortgage-related securities at a premium, mortgage foreclosures or mortgage
prepayments may result in a loss to the Portfolio of up to the amount of the
premium paid since only timely payment of principal and interest is guaranteed.
Alternatively, during periods of rising interest rates, mortgage-related
securities are often more susceptible to extension risk (i.e. rising interest
rates could cause property owners to prepay their mortgage loans more slowly
than expected when the security was purchased by the Portfolio which may further
reduce the market value of such security and lengthen the duration of such
security).

The Portfolio may invest in collateralized mortgage obligations ("CMOs") and
real estate mortgage investment conduits ("REMICs"). CMOs are debt obligations
collateralized by a pool of mortgage loans or mortgaged-related securities which
generally are held under an indenture issued by financial institutions or other
mortgage lenders or issued or guaranteed by agencies or instrumentalities of the
U.S. government. REMICs are private entities formed for the purpose of holding a
fixed pool of mortgages secured by an interest in real property. CMOs and REMICs
generally are issued in a number of classes or series with different maturities.
The classes or series are retired in sequence as the underlying mortgages are
repaid. Such securities generally are subject to market risk, prepayment risk
and extension risk like other mortgage-related securities. Certain of these
securities may have variable or floating interest rates and others may be
stripped (securities which provide only the principal or interest feature of the
underlying security). CMOs or REMICs issued or guaranteed by agencies or
instrumentalities of the U.S. government are treated by the Portfolio as U.S.
government securities.

GOVERNMENT-RELATED SECURITIES. Under normal market conditions, the Portfolio may
invest up to 20% of its assets in, among other things, government-related
securities, including privately issued mortgage-related and mortgage-backed
securities not directly guaranteed by instrumentalities of the U.S. government,
privately issued certificates representing stripped U.S. government or
mortgage-related securities and repurchase agreements fully collateralized by
U.S. government securities.

The Portfolio may invest in private mortgage-related securities ("Private
Pass-Throughs") as opposed to mortgage-related securities issued or guaranteed
by GNMA, FNMA, and FHLMC only if such Private Pass-Throughs are rated at the
time of purchase in the two highest grades by a nationally recognized
statistical rating agency ("NRSRO") or in any unrated debt security considered
by the Portfolio's investment adviser to be of comparable quality. CMOs and
REMICs issued by private entities and not directly guaranteed by any government
agency or instrumentality are secured by the underlying collateral of the
private issuer. The Portfolio will invest in such privately issued securities
only if: they are 100% collateralized at the time of issuance by securities
issued or guaranteed by the U.S. government, its agencies or its
instrumentalities and they are rated at the time of purchase in the two highest
grades by a NRSRO. A more complete description of security ratings, is contained
in the appendix to this prospectus.

The Portfolio may invest in the principal only or interest only components of
U.S. government securities. In the last few years, agencies or instrumentalities
of the U.S. government and a number of banks and brokerage firms have separated
("stripped") the principal portions from the coupon portions of U.S. Treasury
bonds and notes and sold them separately in the form of receipts or certificates
representing undivided interests in these instruments (which instruments are
often held by a bank in a custodial or trust account). Such custodial receipts
or certificates of private issuers are not considered by the Fund to be U.S.
government securities. The principal only securities are not entitled to any
periodic payments of interest prior to maturity. Such securities usually trade
at a deep discount from their face or par value and are subject to greater
fluctuations of market value in response to changing interest rates than debt
obligations of comparable maturities which make current distributions of
interest. Current federal tax law requires that a holder (such as the Portfolio)
of a principal only security accrue a portion of the discount at which the
security was purchased as income each year even though the Portfolio received no
interest payment in cash on the security during the year. The Portfolio is
required to distribute substantially all of its income each year and, in order
to generate sufficient cash to make distributions of such income, the Portfolio
may have to dispose of securities that it would otherwise continue to hold,
which, in some cases may be disadvantageous to the Fund.

Stripped mortgage-related securities (hereinafter referred to as "stripped
mortgage securities") are

                                       45
<PAGE>   125

derivative multiclass mortgage securities. Stripped mortgage securities may be
issued by agencies or instrumentalities of the U.S. government, or by private
originators of, or investors in, mortgage loans, including savings and loan
associations, mortgage banks, commercial banks, investment banks and special
purpose subsidiaries of the foregoing. Stripped mortgage securities usually are
structured with two classes that receive different proportions of the interest
and principal distributions on a pool of mortgage assets. A common type of
stripped mortgage securities will have one class receiving some of the interest
and most of the principal from the mortgage assets, while the other class will
receive most of the interest and the remainder of the principal. In the most
extreme case, one class will receive all of the interest (the interest-only or
"IO" class), while the other class will receive all of the principal (the
principal-only or "PO" class). The yield to maturity on an IO class is extremely
sensitive to the rate of principal payments (including prepayments) on the
related underlying mortgage assets, and a rapid rate of principal payments may
have a material adverse effect on the securities' yield to maturity. If the
underlying mortgage assets experience greater than anticipated prepayments of
principal, the Portfolio may fail to fully recoup its initial investment in
these securities even if the security is rated the highest quality by a NRSRO.
Holders of PO securities are not entitled to any periodic payments of interest
prior to maturity. Accordingly, such securities usually trade at a deep discount
from their face or par value and are subject to greater fluctuations of market
value in response to changing interest rates than debt obligations of comparable
maturities which make current distributions of interest. Current federal tax law
requires that a holder (such as the Portfolio) of principal only securities
accrue a portion of the discount at which the security was purchased as income
each year even though the holder receives no interest payment in cash on the
certificate during the year. In order to generate sufficient cash to make
distributions of such income, the Portfolio may have to dispose of securities
that it would otherwise continue to hold, which, in some cases, may be
disadvantageous to the Portfolio.

Although the market for stripped securities is increasingly liquid, certain of
such securities may not be readily marketable and will be considered illiquid
for purposes of the Portfolio's limitation on investments in illiquid
securities. The Portfolio will follow established guidelines and standards for
determining whether a particular stripped security is liquid. Generally, such a
security may be deemed liquid if it can be disposed of promptly in the ordinary
course of business at a value reasonably close to that used in the calculation
of the net asset value per share. Stripped mortgage securities, other than
government-issued IO and PO securities backed by fixed-rate mortgages, are
presently considered by the staff of the SEC to be illiquid securities and thus
subject to the Portfolio's limitation on investment in illiquid securities.

INTEREST RATE TRANSACTIONS. The Portfolio may enter into interest rate swaps and
may purchase or sell interest rate caps, floors and collars. The Portfolio
expects to enter into these transactions primarily to preserve a return or
spread on a particular investment or portion of its portfolio. The Portfolio may
also enter into these transactions to protect against any increase in the price
of securities the Portfolio anticipates purchasing at a later date. Interest
rate swaps, caps, floors and collars will be treated as illiquid securities for
the purposes of the Portfolio's investment restriction limiting investment in
illiquid securities. Besides liquidity, such transactions include market risk,
risk of default by the other party to the transaction, risk of imperfect
correlation and manager risk. Such transactions may involve commissions or other
costs. A more complete discussion of interest rate transactions and their risks
is contained in the Statement of Additional Information.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase or sell
U.S. government securities on a "when-issued" or "delayed delivery" basis
("Forward Commitments"). These transactions occur when securities are purchased
or sold by the Portfolio with payment and delivery taking place in the future,
frequently a month or more after such transaction. The price is fixed on the
date of the commitment, and the seller continues to accrue interest on the
securities covered by the Forward Commitment until delivery and payment take
place. At the time of settlement, the market value of the securities may be more
or less than the purchase or sale price. The Portfolio may either settle a
Forward Commitment by taking delivery of the securities or may either resell or
repurchase a Forward Commitment on or before the settlement date in which event
the Portfolio may reinvest the proceeds in another Forward Commitment. These
transactions are subject to market risk as the value or yield of a security at
delivery may be more or less than the purchase price or the yield generally
available on securities when delivery occurs. When engaging in Forward
Commitments, the Portfolio relies on the other party to complete the
transaction, should the other party fail to do so, the Portfolio might lose a
purchase or sale opportunity that could be more advantageous than alternative
opportunities at the time of the failure.

                                       46
<PAGE>   126

The Portfolio maintains a segregated account (which is marked to market daily)
of cash or liquid portfolio securities with the Portfolio's custodian in an
aggregate amount equal to the amount of its commitment as long as the obligation
to purchase or sell continues.

                          GROWTH AND INCOME PORTFOLIO

The investment objective of the Growth and Income Portfolio is to seek long-term
growth of capital and income. There are risks inherent in all investments in
securities; accordingly, there can be no assurance that the Portfolio will
achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing primarily in income-producing
equity securities, including common stocks and convertible securities; although
investments are also made in non-convertible preferred stocks and debt
securities rated "investment grade," which are securities rated within the four
highest grades assigned by Standard & Poor's ("S&P") or by Moody's Investors
Service, Inc. ("Moody's"). A more complete description of security ratings is
contained in the appendix to this prospectus.

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so.

A convertible security is a bond, debenture, note, preferred stock, warrant or
other security that may be converted into or exchanged for a prescribed amount
of common stock or other equity security of the same or a different issuer
within a particular period of time at a specified price or formula. A
convertible security generally entitles the holder to receive interest paid or
accrued on debt or the dividend paid on preferred stock until the convertible
security matures or is redeemed, converted or exchanged. Before conversion,
convertible securities generally have characteristics similar to both debt and
equity securities. The value of convertible securities tends to decline as
interest rates rise and, because of the conversion feature, tends to vary with
fluctuations in the market value of the underlying equity security. Convertible
securities ordinarily provide a stream of income with generally higher yields
than those of common stock of the same or similar issuers. Convertible
securities generally rank senior to common stock in a corporation's capital
structure but are usually subordinated to comparable nonconvertible securities.
Convertible securities generally do not participate directly in any dividend
increases or decreases of the underlying equity security although the market
prices of convertible securities may be affected by any such dividend changes or
other changes in the underlying equity security.

While the Portfolio invests primarily in income-producing equity securities, the
Portfolio may invest in non-convertible adjustable or fixed rate preferred stock
and debt securities. Preferred stock generally has a preference as to dividends
and liquidation over an issuer's common stock but ranks junior to debt
securities in an issuer's capital structure. Unlike interest payments on debt
securities, preferred stock dividends are payable only if declared by the
issuer's board of directors. Preferred stock also may be subject to optional or
mandatory redemption provisions. The Portfolio may invest in debt securities of
various maturities. The Portfolio invests only in debt securities rated
investment grade at the time of investment, and a subsequent reduction in rating
does not require the Portfolio to dispose of a security. Securities rated BBB by
S&P or Baa by Moody's are in the lowest of the four investment grades and are
considered by the rating agencies to be medium grade obligations which possess
speculative characteristics so that changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than in the case of higher rated securities. A more
complete description of security ratings is contained in the appendix to this
prospectus. The market prices of debt securities generally fluctuate inversely
with changes in interest rates so that the value of investments in such
securities can be expected to decrease as interest rates rise and increase as
interest rates fall and such fluctuations generally are larger among securities
with longer durations.

In selecting common stocks for investment, the Portfolio will focus primarily on
the security's potential for capital growth and income. The Portfolio's
investment adviser may focus on larger capitalization companies which it
believes possess characteristics for improved valuation. The Portfolio may
invest in issuers of small-, medium- or large-capitalization companies. The
securities of small- or medium-sized companies may be subject to more abrupt or
erratic market movements than securities of larger, more established companies
or the market averages in general. In addition, such companies

                                       47
<PAGE>   127

typically are subject to a greater degree of change in earnings and business
prospects than are larger, more established companies. Thus, the Portfolio may
be subject to greater investment risk than that assumed through investment in
the equity securities of larger, more established companies.

The Portfolio may dispose of a security whenever, in the opinion of the
Portfolio's investment adviser, factors indicate it is desirable to do so. Such
factors include change in economic or market factors in general or with respect
to a particular industry, a change in the market trend or other factors
affecting an individual security, changes in the relative market performance or
appreciation possibilities offered by individual securities and other
circumstances bearing on the desirability of a given investment.

The Portfolio may invest up to 15% of its total assets in securities of foreign
issuers. See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                             MONEY MARKET PORTFOLIO

The investment objective of the Money Market Portfolio is to seek protection of
capital and high current income through investments in money market instruments.
There are risks inherent in all investments in securities; accordingly there can
be no assurance that the Portfolio will achieve its investment objective.

The Portfolio seeks to maintain a constant net asset value of $1.00 per share by
investing in a diversified portfolio of money market instruments maturing within
one year with a dollar-weighted average maturity of 90 days or less. The
Portfolio seeks high current income from these short-term investments to the
extent consistent with protection of capital.

The investment policies, the percentage limitations, and the kinds of securities
in which the Portfolio can invest may be changed by the Portfolio's Board of
Trustees, unless expressly governed by those limitations stated under
"Investment Restrictions" in the Trust's Statement of Additional Information
which can be changed only by action of the shareholders of the Portfolio. It is
not the intention of the Portfolio's Trustees, however, to change these policies
without prior notice to shareholders.

There are risks inherent in all investments in securities, accordingly there can
be no assurance that the Portfolio will achieve its investment objective or that
the Portfolio will be able at all times to preserve the net asset value per
share at $1.00 per share. The daily dividend rate paid by the Portfolio is
expected to fluctuate with changes in prevailing market interest rates. The
Portfolio uses the amortized cost method for valuing portfolio securities
purchased at a discount.

The Portfolio may invest in money market instruments of the following types, all
of which will be U.S. dollar obligations:

OBLIGATIONS OF THE U.S. GOVERNMENT, ITS AGENCIES OR ITS INSTRUMENTALITIES. The
Portfolio may invest in obligations issued or guaranteed as to principal and
interest by the U.S. government, its agencies or its instrumentalities which are
supported by any of the following: (a) the full faith and credit of the U.S.
government, (b) the right of the issuer to borrow an amount limited to a
specific line of credit from the U.S. government, (c) discretionary authority of
the U.S. government to purchase obligations of its agencies or instrumentalities
or (d) the credit of the instrumentality. Such agencies or instrumentalities
include, but are not limited to, the Federal National Mortgage Association, the
Government National Mortgage Association, Federal Land Banks, and the Farmer's
Home Administration.

BANK OBLIGATIONS. The Portfolio may invest in negotiable time deposits,
certificates of deposit and bankers' acceptances which are obligations of
domestic banks having total assets in excess of $1 billion as of the date of
their most recently published financial statements. The Portfolio is also
authorized to invest up to 5% of its total assets in certificates of deposit
issued by domestic banks having total assets of less than $1 billion, provided
that the principal amount of the certificate of deposit acquired by the
Portfolio is insured in full by the Federal Deposit Insurance Corporation.

COMMERCIAL PAPER. The Portfolio may invest in short-term commercial paper
obligations of companies which at the time of investment are (a) rated in

                                       48
<PAGE>   128

one of the two highest categories by at least two nationally recognized
statistical organizations (or one rating organization if the obligation was
rated by only one such organization) or (b) if unrated, are of comparable
quality as determined in accordance with procedures established by the
Portfolio's Board of Trustees. Commercial paper consists of short-term (usually
from 1 to 270 days) unsecured promissory notes issued by corporations in order
to finance their current operations. The Portfolio's current policy is to limit
investments in commercial paper to obligations rated in the highest rating
category. A more complete description of security ratings is in the appendix to
this prospectus.

REPURCHASE AGREEMENTS. The Portfolio may enter into repurchase agreements with
banks and broker-dealers which involve certain risks in the event of a default
by the other party. See "Investment Practices -- Repurchase Agreements" below
and in the Statement of Additional Information.

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                                 MORGAN STANLEY

                        REAL ESTATE SECURITIES PORTFOLIO

The primary investment objective of the Morgan Stanley Real Estate Securities
Portfolio is to seek long-term growth of capital. Current income is a secondary
investment objective. There are risks inherent in all investments in securities;
accordingly, there can be no assurance that the Portfolio will achieve its
investment objectives.

The Portfolio's investment adviser seeks to achieve the investment objectives by
investing primarily in a portfolio of securities of companies operating in the
real estate industry. A company operating in the real estate industry is one
that derives at least 50% of its assets (marked-to-market), gross income or net
profits from the ownership, construction, management or sale of residential,
commercial or industrial real estate. Real estate industry companies include,
among others: equity real estate investment trusts, which pool investors' funds
for investment primarily in commercial real estate properties; mortgage real
estate investment trusts, which invest pooled funds in real estate related
loans; brokers or real estate developers; and companies with substantial real
estate holdings, such as paper and lumber products and hotel and entertainment
companies. Because of the Portfolio's policy of concentrating its investments in
real estate securities, the Portfolio may be more susceptible to economic,
political or regulatory occurrences affecting the real estate industry than a
portfolio without such a policy.

Under normal market conditions, the Portfolio invests at least 65% of its total
assets in securities of companies operating in the real estate industry,
including equity securities of REITs and other securities of real estate
operating companies. The Portfolio's investment adviser diversifies its
investments as to issuers, property types and regions. The investment adviser's
approach emphasizes a bottom-up stock selection with a top-down asset allocation
overlay. Besides equity securities of REITs, the Portfolio also invests in
equity securities, including common stocks and convertible securities, or non-
convertible preferred stocks and investment-grade debt securities of real estate
industry companies. REITs pool investors' funds for investment primarily in
income producing real estate or real estate related loans or interests. REITs
can generally be classified as equity REITs, mortgage REITs or a combination of
both. Equity REITs, which invest the majority of their assets directly in real
property, derive their income from rents. Equity REITs can also realize capital
gains by selling properties that have appreciated in value. Mortgage REITs,
which invest the majority of their assets in real estate mortgagees, derive
their income primarily from interest payments. REITs are not taxed on income
distributed to shareholders provided such REITs comply with several requirements
of the Internal Revenue Code of 1986, as amended (the "Code").

Common stocks are shares of a corporation or other entity that entitle the
holder to a pro rata share of the profits of the corporation, if any, without
preference over any other class of securities, including such entity's debt
securities, preferred stock and other senior equity securities. Common stock
usually carries with it the right to vote and frequently an exclusive right to
do so.

A convertible security is a bond, debenture, note, preferred stock, warrant or
other security that may be converted into or exchanged for a prescribed amount
of common stock or other equity security of the same or a different issuer
within a particular period of time at a specified price or formula. A
convertible security generally entitles the holder to receive interest paid or
accrued on debt securities or the dividend paid on preferred stock until the
convertible security matures or is redeemed, converted or exchanged. Before
conversion,

                                       49
<PAGE>   129

convertible securities generally have characteristics similar to both debt and
equity securities. The value of convertible securities tends to decline as
interest rates rise and, because of the conversion feature, tends to vary with
fluctuations in the market value of the underlying equity security. Convertible
securities ordinarily provide a stream of income with generally higher yields
than those of common stock of the same or similar issuers. Convertible
securities generally rank senior to common stock in a corporation's capital
structure but are usually subordinated to comparable nonconvertible securities.
Convertible securities generally do not participate directly in any dividend
increases or decreases of the underlying equity security although the market
prices of convertible securities may be affected by any such dividend changes or
other changes in the underlying equity security.

Preferred stock generally has a preference as to dividends and liquidation over
an issuer's common stock but ranks junior to debt securities in an issuer's
capital structure. Unlike interest payments on debt securities, preferred stock
dividends are payable only if declared by an issuer's board of directors.
Preferred stock may be subject to optional or mandatory redemption provisions.
The ability of common stocks and preferred stocks to generate income is
dependent on the earnings and continuing declaration of dividends by the issuers
of such securities.

Debt securities of a corporation or other entity generally entitle the holder to
receive interest, at a fixed, variable or floating interest rate, during the
term of the security and repayment of principal at maturity or redemption. The
Portfolio invests in investment-grade debt securities (securities rated at the
time of investment BBB or higher by Standard & Poor's ("S&P") or rated Baa or
higher by Moody's Investors Service, Inc. ("Moody's") or comparably rated by
another nationally recognized statistical rating organization ("NRSRO") or
unrated securities considered by the Portfolio's investment adviser to be of
comparable quality). Credit quality at the time of purchase determines which
securities may be acquired, and a subsequent reduction in ratings does not
require the Portfolio to dispose of a security. Securities rated BBB by S&P or
Baa by Moody's are considered to be medium-grade obligations which possess
speculative characteristics so that changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity to make principal
and interest payments than in the case of higher-rated securities. The ratings
assigned by the ratings agencies represent their opinions of the quality of the
debt securities they undertake to rate, but not the market value risk of such
securities. It should be emphasized that ratings are general and are not
absolute standards of quality. A more complete description of security ratings
is contained in the appendix to this prospectus.

Under normal market conditions, the Portfolio may invest up to 35% of its total
assets in securities of companies outside the real estate industry.

The Portfolio may invest up to 25% of its total assets in securities issued by
foreign issuers, some or all of which also may be in the real estate industry.
See "Investment Practices -- Foreign Securities."

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

RISK FACTORS OF INVESTING IN REAL ESTATE SECURITIES. The values and return on
securities of companies in the real estate industry may or may not fluctuate in
tandem with the overall securities' markets. Although the Portfolio does not
invest directly in real estate, an investment in the Portfolio generally will be
subject to the risks associated with investments in real estate because of its
policy of concentrating in the securities of companies operating in the real
estate industry. These risks include, among others: declines in the value of
real estate; defaults by borrowers or tenants; risks related to general and
local economic conditions; overbuilding and increased competition; increases in
property taxes, capital expenditures or operating expenses; changes in zoning
laws; casualty or condemnation losses; variations in rental income; changes in
neighborhood values; the appeal of properties to tenants; changes in interest
rates; and political or regulatory occurrences affecting the real estate
industry. The value of securities of companies which service the real estate
industry also will be affected by such risks. If the Portfolio has rental income
or income from the disposition of real property acquired as a result of a
default on securities the Portfolio may own, the receipt of such income may
adversely affect the Portfolio's ability to retain its tax status as a regulated
investment company.

Equity REITs may be affected by changes in the value of the underlying property
owned by the trusts, while

                                       50
<PAGE>   130

mortgage REITs may be affected by changes in interest rates and the quality of
credit extended. Equity and mortgage REITs are dependent upon management skill,
may not be diversified (which may increase the volatility of the REIT's value)
and are subject to the risks of financing projects. REITs are subject to heavy
cash flow dependency, defaults by borrowers, self-liquidation and the
possibility of failing to qualify for tax-free pass-through of income under the
Code and to maintain exemption from the Investment Company Act of 1940, as
amended (the "1940 Act"). REITs are not taxed on income distributed to
shareholders provided they comply with several requirements of the Code.
Mortgage REITs, like debt securities, tend to decline in value as interest rates
rise. Mortgage REITs are often more susceptible than traditional debt securities
to further price declines in periods of rising interest rates because of
extension risks (i.e. rising interest rates could cause property owners to
prepay their mortgages more slowly than expected when the security was purchased
by the Portfolio which may further reduce the market value of such security and
lengthen the duration of the security). In addition, mortgage REITs tend to
benefit less than traditional debt securities when interest rates decline
because underlying mortgages often get prepaid faster than expected in periods
of declining interest rates. In addition, the Portfolio indirectly will bear its
proportionate share of any expenses paid by the REITs in which it invests.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase and sell
debt securities on a "when-issued" or "delayed delivery" basis ("Forward
Commitments"). These transactions occur when securities are purchased or sold by
the Portfolio with payment and delivery taking place in the future, frequently a
month or more after such transaction. The price is fixed on the date of the
commitment, and the seller continues to accrue interest on the securities
covered by the Forward Commitment until delivery and payment take place. At the
time of settlement, the market value of the securities may be more or less than
the purchase or sale price. The Portfolio may either settle a Forward Commitment
by taking delivery of the securities or may either resell or repurchase a
Forward Commitment on or before the settlement date in which event the Portfolio
may reinvest the proceeds in another Forward Commitment. These transactions are
subject to market risk as the value or yield of a security at delivery may be
more or less than the purchase price or the yield generally available on
securities when delivery occurs. When engaging in Forward Commitments, the
Portfolio relies on the other party to complete the transaction, should the
other party fail to do so, the Portfolio might lose a purchase or sale
opportunity that could be more advantageous than alternative opportunities at
the time of the failure. The Portfolio maintains a segregated account (which is
marked to market daily) of cash or liquid portfolio securities with the
Portfolio's custodian in an aggregate amount equal to the amount of its
commitment as long as the obligation to purchase or sell continues.

                           STRATEGIC STOCK PORTFOLIO

The investment objective of the Strategic Stock Portfolio is to seek an above
average total return through a combination of potential capital appreciation and
dividend income, consistent with the preservation of invested capital. There are
risks inherent in all investments in securities; accordingly, there can be no
assurance that the Portfolio will achieve its investment objective.

Under normal market conditions, the Portfolio's investment adviser seeks to
achieve the investment objective by investing in a portfolio of high dividend
yielding equity securities of companies included in the DJIA or in the MSCI USA
Index. The DJIA was first published in The Wall Street Journal in 1896.
Initially consisting of just 12 stocks, the DJIA expanded to 20 stocks in 1916
and to its present size of 30 stocks on October 1, 1928. The MSCI USA Index
consists of approximately 370 large domestic companies in the United States and
has existed since January 1, 1970.

The Portfolio's investment adviser selects investment securities for the
Portfolio based upon the Portfolio's strategic selection policies (the
"Strategic Selection Policies") as follows:

The ten highest dividend yielding securities in the DJIA are identified for
investment. In addition, all companies having securities in the MSCI USA Index
are reviewed by the Portfolio's investment adviser. Securities of companies in
the financial or utility sectors and companies having securities included in the
DJIA are excluded. The remaining pool of MSCI USA Index securities is further
evaluated and securities of companies that do not have positive one- and
three-year sales and earnings growth rates and two years of positive dividend
growth are excluded. The Portfolio's investment adviser also excludes MSCI USA
Index securities that are in the bottom 25% of all MSCI USA Index securities
measured in terms of total annual trading

                                       51
<PAGE>   131

volume. MSCI USA Index securities of the remaining companies are ranked by
dividend yield, and the ten highest-yielding such MSCI USA Index securities are
identified for investment. In the event that this process results in less than
10 remaining MSCI USA Index securities, those companies with the most favorable
one- and three-year sales and earnings performance and two-year dividend
performance as determined by the Portfolio's investment adviser are added back
until the number of MSCI USA Index securities equals 10. Dividend yield for
purposes of applying the foregoing investment policies is calculated for each
security by annualizing the last quarterly or semi-annual ordinary dividend
declared on the security and dividing the result by the security's closing sale
price on the applicable date. This yield is historical and there can be no
assurance that any dividends will be declared or paid in the future.

At the commencement of the Portfolio's investment operations, the 20 securities
so identified at that time represented the Portfolio's initial investments.
Approximately monthly, the Portfolio's investment adviser employs the same
Strategic Selection Policies to identify a new list of 20 strategic securities.
Based on a rolling 12-month schedule, the investment adviser reviews and adjusts
the oldest one-twelfth portion of the Portfolio's assets so as to invest that
portion of the Portfolio's assets approximately equally in the new list of 20
strategic securities. For a more detailed discussion of the Portfolio's
investment policies, including the frequency of security re-evaluations and the
portion of the Portfolio's assets that the Portfolio's investment adviser
presently expects to re-evaluate at the end of each period, see the Statement of
Additional Information.

The Portfolio's investment adviser generally seeks to allocate cash available
for investment due to the sale of new shares of the Portfolio and the receipt of
dividends and interest income from Portfolio investments approximately
proportionately among its current list of strategic securities in the Portfolio.
To the extent that the Portfolio is required to dispose of securities in order
to satisfy redemption requests, make distributions, pay expenses or otherwise
raise cash for operational purposes, the Portfolio's investment adviser
generally intends to sell approximately proportionate amounts of securities from
all securities in the Portfolio.

Application of the foregoing Strategic Selection Policies is subject to and
limited by certain of the Portfolio's other investment policies and
restrictions, including restrictions and limitations which must be met in order
for the Portfolio to qualify for U.S. federal income tax purposes as a
"regulated investment company" under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"), or in order to comply with requirements of the
1940 Act. The Portfolio is subject to investment diversification requirements
that generally provide that the Portfolio may not, with respect to 75% of its
assets, invest more than 5% of its assets in the securities of any one issuer or
purchase more than 10% of the outstanding voting securities of any one issuer.
Further, the Portfolio generally may not invest more than 25% of the value of
its total assets in securities of issuers in any particular industry. The
Portfolio's satisfaction of these requirements will take precedent over the
Strategic Selection Policies. In addition, the Portfolio's investment adviser
will try to avoid transacting in odd-lots of securities in order to minimize
transaction costs. These limitations may, at times, cause the composition of the
Portfolio's investment portfolio to differ significantly from that which would
have resulted had the Strategic Selection Policies been fully implemented. In
selecting securities for investment or disposition at times that the Portfolio's
investment policies and restrictions do not permit full implementation of the
Strategic Selection Policies, the Portfolio's investment adviser will have sole
discretion to select securities for purchase or sale and generally will make
such selections in a manner that is consistent with the Portfolio's investment
objective and in a manner that it believes is consistent with the investment
rationale that is the basis for the Strategic Selection Policies.

The Portfolio will continue to hold securities, even though such securities may
not be included in the most recent list of strategic securities determined for
the review and adjustment of a portion of the Portfolio's assets. In addition,
although each new list of strategic securities will include only 20 securities,
because only a portion of the Portfolio's assets may be reviewed and adjusted at
any given time, the Portfolio's investment adviser expects that the number of
securities held by the Portfolio may over time increase and that the Portfolio
may at times hold forty or more different securities.

The Portfolio may invest up to 5% of its total assets in options on equity
securities indices, futures contracts on such indices and options on such
futures contracts for both hedging purposes and in an attempt to enhance gain.
The Portfolio also may invest up to 5% of its total assets in securities of
other registered investment companies that seek to provide investment results
that generally correspond to the performance of securities included in one or
more

                                       52
<PAGE>   132

broad market indices. Investment in securities of other investment companies
will subject the Portfolio to additional and potentially duplicative costs and
expenses, including investment management fees charged by such registered
investment companies. Pending investment and for temporary defensive purposes
the Portfolio may invest without limit in short-term, high quality fixed income
securities and in money-market instruments.

RISK FACTORS. There is no guarantee that the investment objective of the
Portfolio will be achieved because it is subject to the continuing ability of
the respective issuers of equity securities in which the Portfolio invests to
declare and pay dividends and because the market value of such equity securities
can be affected by a variety of factors. Common stocks may be especially
susceptible to general stock market movements and to volatile increases and
decreases of value as market confidence in and perceptions of the issuers
change. There can be no assurance that the value of the underlying securities
will increase or that the issuers of the securities will pay dividends on
outstanding securities. The declaration of dividends by any issuer depends upon
several factors including the financial condition of the issuer and general
economic conditions. Risks associated with an investment in the Portfolio
include the possible deterioration of either the financial condition of the
issuers or the general condition of the stock market, and general price
volatility. The relatively high dividend yield of certain securities that the
Portfolio will acquire may reflect the market's assessment of the risk that the
company may reduce or eliminate the dividend in the current period or in the
future, or otherwise reflect the market's unfavorable assessment of the
company's performance outlook. The Portfolio's investment adviser generally will
not take these considerations into account in implementing the Strategic
Selection Policies and, accordingly, the Portfolio may at times acquire
securities of companies that the market and the Portfolio's investment adviser
believe are more susceptible to financial difficulty and corresponding adverse
market performance than are

                                       53
<PAGE>   133

other companies with securities included in the DJIA or in the MSCI USA Index.

In addition, investors should be aware that the Portfolio is not "actively
managed." Except to raise cash for operational purposes, the Portfolio
ordinarily will not sell securities or re-evaluate its investments except as
periodically determined by the Portfolio's investment adviser. In addition, only
a portion of the Portfolio's assets may be reviewed and adjusted for any given
period. As a result, although the Portfolio may (but need not) dispose of a
security in certain events such as the issuer having defaulted on the payment on
any of its outstanding obligations or the price of a security having declined to
such an extent or other factors existing so that in the opinion of the
Portfolio's investment adviser the retention of such security would be
detrimental to the Portfolio, the adverse financial condition of a company will
not result in its elimination from the Portfolio prior to scheduled review and
adjustment except under extraordinary circumstances. Similarly, securities held
in the Portfolio ordinarily will not be sold by the Portfolio for the purpose of
taking advantage of market fluctuations or changes in anticipated rates of
appreciation.

The Portfolio may engage in portfolio management strategies and techniques
involving options, futures contracts and options on futures which may subject
the Portfolio to additional risks. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts."

Other investment practices and risks of the Portfolio are described under the
heading "Investment Practices."

                              INVESTMENT PRACTICES

                             REPURCHASE AGREEMENTS

Each Portfolio may enter into repurchase agreements with banks or broker-dealers
in order to earn a return on temporarily available cash. A repurchase agreement
is a short-term investment in which the purchaser (i.e., the Portfolio) acquires
ownership of a debt security and the seller agrees to repurchase the obligation
at a future time and set price, thereby determining the yield during the holding
period. Repurchase agreements involve certain risks in the event of default by
the other party. Each Portfolio may enter into repurchase agreements with banks
or broker-dealers deemed to be creditworthy by the Portfolio's investment
adviser under guidelines approved by the Portfolio's Board of Trustees. No
Portfolio will invest in repurchase agreements maturing in more than seven days
if any such investment, together with any other illiquid securities held by such
Portfolio, would exceed the Portfolio's limitation on illiquid securities
described below. In the event of the bankruptcy or other default of a seller of
a repurchase agreement, a Portfolio could experience both delays in liquidating
the underlying securities and losses including: (a) possible decline in the
value of the underlying security during the period while the Portfolio seeks to
enforce its rights thereto; (b) possible lack of access to income on the
underlying security during this period; and (c) expenses of enforcing its
rights.

For the purpose of investing in repurchase agreements, a Portfolio's investment
adviser may aggregate the cash that certain funds or portfolios advised or
subadvised by the investment adviser or certain of its affiliates would
otherwise invest separately into a joint account. The cash in the joint account
is then invested in repurchase agreements and the funds or portfolios that
contributed to the joint account share pro rata in the net revenue generated.
The investment adviser believes that the joint account produces efficiencies and
economies of scale that may contribute to reduced transaction costs, higher
returns, higher quality investments and greater diversity of investments for the
participating Portfolio than would be available to the Portfolio investing
separately. The manner in which the joint account is managed is subject to
conditions set forth in an exemptive order from the SEC authorizing this
practice, which conditions are designed to ensure the fair administration of the
joint account and to protect the amounts in that account.

Repurchase agreements are fully collateralized by the underlying debt securities
and are considered to be loans under the 1940 Act. A Portfolio pays for such
securities only upon physical delivery or evidence of book entry transfer to the
account of a custodian or bank acting as agent. The seller under a repurchase
agreement will be required to maintain the value of the underlying securities
marked-to-market daily at not less than the repurchase price. The underlying
securities (normally securities of the U.S. government, or its agencies and its
instrumentalities) may have maturity dates exceeding one year. A Portfolio

                                       54
<PAGE>   134

does not bear the risk of a decline in value of the underlying security unless
the seller defaults under its repurchase obligation.

                               FOREIGN SECURITIES

Each of the Portfolios listed below may invest in securities issued by foreign
issuers up to the following limits:

<TABLE>
<S>                         <C>
Asset Allocation Portfolio  Up to 25% of total assets
 ..........................................................

Morgan Stanley Real Estate
Securities Portfolio        Up to 25% of total assets
 ..........................................................
</TABLE>

Such securities may be denominated in U.S. dollars or in currencies other than
U.S. dollars. Investments in foreign securities present certain risks not
ordinarily associated with investments in securities of U.S. issuers. These
risks include fluctuations in foreign currency exchange rates, political,
economic or legal developments (including war or other instability,
expropriation of assets, nationalization and confiscatory taxation), imposition
of foreign exchange limitations (including currency blockage), withholding taxes
on dividend or interest payments or capital transactions or other restrictions,
higher transaction costs (including higher brokerage, custodial and settlement
costs and currency translation costs) and possible difficulty in enforcing
contractual obligations or taking judicial action. Also, foreign securities may
not be as liquid and may be more volatile than comparable domestic securities.

In addition, there often is less publicly available information about many
foreign issuers, and issuers of foreign securities are subject to different,
often less comprehensive, auditing, accounting, financial reporting and
disclosure requirements than domestic issuers. There is generally less
government regulation of stock exchanges, brokers and listed companies abroad
than in the U.S., and, with respect to certain foreign countries, there is a
possibility of expropriation or confiscatory taxation, or diplomatic
developments which could affect investment in those countries. Because there is
usually less supervision and governmental regulation of exchanges, brokers and
dealers than there is in the U.S., a Portfolio may experience settlement
difficulties or delays not usually encountered in the U.S.

Delays in making trades in foreign securities relating to volume constraints,
limitations or restrictions, clearance or settlement procedures, or otherwise
could impact yields and result in temporary periods when assets are not fully
invested or attractive investment opportunities are foregone.

A Portfolio's investments in securities of developing or emerging markets are
subject to greater risks than a Portfolio's investments in securities of
developed countries since emerging markets tend to have economic structures that
are less diverse and mature and political systems that are less stable than
developed countries.

Each of these Portfolios may purchase foreign securities in the form of American
Depository Receipts, European Depositary Receipts or other securities
representing underlying shares of foreign companies. The risks of foreign
investments should be considered carefully by an investor in a Portfolio that
invests in foreign securities.

                         FOREIGN CURRENCY TRANSACTIONS

Each Portfolio's securities that are denominated or quoted in currencies other
than the U.S. dollar will be affected by changes in foreign currency exchange
rates (and exchange control regulations) which affects the value of the
securities in the Portfolio and the income or dividends and appreciation or
depreciation of its investments. Changes in foreign currency exchange ratios
relative to the U.S. dollar will affect the U.S. dollar value of the Portfolio's
assets denominated in that currency and the Portfolio's yield on such assets. In
addition, the Portfolio will incur costs in connection with conversions between
various currencies. A Portfolio's foreign currency exchange transactions
generally will be conducted on a spot basis (that is, cash basis) at the spot
rate for purchasing or selling currency prevailing in the foreign currency
exchange market. A Portfolio purchases and sells foreign currency on a spot
basis in connection with the settlement of transactions in securities traded in
such foreign currency. The Portfolios do not purchase and sell foreign
currencies as an investment.

                                       55
<PAGE>   135

A Portfolio also may enter into contracts with banks or other foreign currency
brokers and dealers to purchase or sell foreign currencies at a future date
("forward contracts") and purchase and sell foreign currency futures contracts
to hedge against changes in foreign currency exchange rates. A foreign currency
forward contract is a negotiated agreement between the contracting parties to
exchange a specified amount of currency at a specified future time at a
specified rate. The rate can be higher or lower than the spot rate between the
currencies that are the subject of the contract.

A Portfolio may attempt to hedge against changes in the value of the U.S. dollar
in relation to a foreign currency by entering into a forward contract for the
purchase or sale of the amount of foreign currency invested or to be invested,
or by buying or selling a foreign currency futures contract for such amount.
Futures contracts are described below under the heading "Investment
Practices -- Using Options, Futures Contracts and Options in Futures Contracts."
Such hedging strategies may be employed before a Portfolio purchases a foreign
security traded in the hedged currency which a Portfolio anticipates acquiring
or between the date the foreign security is purchased or sold and the date on
which payment therefore is made or received. Hedging against a change in the
value of a foreign currency in the foregoing manner does not eliminate
fluctuations in the price of portfolio securities or prevent losses if the
prices of such securities decline. Furthermore, such hedging transactions reduce
or preclude the opportunity for gain if the value of the hedged currency should
move in the direction opposite to the hedged position. Unanticipated changes in
currency prices may result in poorer overall performance for the Portfolio than
if it had not entered into such contracts.

The Portfolio's custodian will place cash or liquid securities in a segregated
account having a value equal to the aggregate amount of the Portfolio's
commitments under forward contracts. If the value of the securities placed in
the segregated account declines, additional cash or securities are placed in the
account on a daily basis so that the value of the account equals the amount of
the Portfolio's commitments with respect to such contracts. As an alternative to
maintaining all or part of the segregated account, the Portfolio may purchase a
call option permitting the Portfolio to purchase the amount of foreign currency
by a forward sale contract at a price no higher than the forward contract price
or the Portfolio may purchase a put option permitting the Portfolio to sell the
amount of foreign currency subject to a forward purchase contract at a price as
high or higher than the forward contract price.

                              ILLIQUID SECURITIES

Each of the Portfolios listed below may invest in illiquid securities and
certain restricted securities up to the following limits:

<TABLE>
<S>                        <C>
Asset Allocation           Up to 5% of net assets

</TABLE>

Such securities may be difficult or impossible to sell at the time and the price
that the Portfolio would like. Thus, the Portfolio may have to sell such
securities at a lower price, sell other securities instead to obtain cash or
forego other investment opportunities.

       USING OPTIONS, FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

Each Portfolio (excluding the Domestic Income Portfolio and the Money Market
Portfolio) may use options, futures contracts or options on futures contracts in
several different ways, depending upon the status of a Portfolio's portfolio
securities and the investment adviser's expectations concerning the securities
or currency markets.

In times of stable or rising securities' prices, the Portfolios generally seek
to be fully invested. Even when the Portfolios are fully invested, however,
prudent management requires that at least a small portion of assets be available
as cash to honor redemption requests and for other short-term needs. The
Portfolios may also have cash on hand that has not yet been invested. The
portion of a Portfolio's assets that is invested in cash or cash equivalents
does not fluctuate with overall market prices, so that, in times of rising
market prices, the Portfolio may

                                       56
<PAGE>   136

underperform the market in proportion to the amount of cash or cash equivalents
in the Portfolio. By purchasing stock or bond index futures contracts, however,
the Portfolios can compensate for the cash portion of its assets and may obtain
performance equivalent to investing all of its assets in securities.

If the Portfolios' investment adviser forecasts a market decline, the Portfolios
may seek to reduce its exposure to the securities markets by increasing its cash
position. By selling stock or bond index futures contracts instead of Portfolio
securities, a similar result can be achieved to the extent that the performance
of the futures contracts correlates to the performance of the Portfolios'
investments. Sales of futures contracts frequently may be accomplished more
rapidly and at less cost than the actual sale of securities. Once the desired
hedged position has been effected, the Portfolios could then liquidate
securities in a more deliberate manner, reducing its futures position
simultaneously to maintain the desired balance, or it could maintain the hedged
position.

As an alternative to futures contracts, the Portfolios can engage in options (or
stock or bond index options or stock or bond index futures options) to manage
the Portfolios' risk in advancing or declining markets. For example, the value
of a put option generally increases as the underlying security declines below a
specified level, value is protected against a market decline to the degree the
performance of the put correlates with the performance of the Portfolios'
investment portfolio. If the market remains stable or advances, the Portfolios
can refrain from exercising the put and the Portfolios will participate in the
advance, having incurred only the premium cost for the put.

The Portfolios are authorized to purchase and sell listed and over-the-counter
options ("OTC Options"). OTC Options are subject to certain additional risks
including default by the other party to the transaction and the liquidity of the
transactions.

In addition to futures and options on securities, the Portfolios may engage in
foreign currency futures and options. The Portfolios may use currency options to
increase its gross income or to protect it against declines in the U.S. dollar
value of foreign currency denominated securities and against increases in the
U.S. dollar cost of such securities to be acquired. As in the case of other
kinds of options, however, the selling of an option on a foreign currency
constitutes only a partial hedge, up to the amount of the premium received, and
the Portfolios could be required to cover its position by purchasing or selling
foreign currencies at disadvantageous exchange rates, thereby incurring losses.
The purchase of an option on a foreign currency may constitute an effective
hedge against fluctuations in exchange rates although, in the event of rate
movements adverse to a Portfolio's position, the Portfolio may forfeit the
entire amount of the premium plus related transaction costs. Options on foreign
currencies in which the Portfolios invest are traded on U.S. and foreign
exchanges or over-the-counter.

In certain cases, the options and futures markets provide investment or risk
management opportunities that are not available from direct investments in
securities. In addition, some strategies can be performed with greater ease and
at lower cost by utilizing the options and futures markets rather than
purchasing or selling portfolio securities or currencies. However, such
transactions involve risks different from the direct investment in underlying
securities such as imperfect correlation between the value of the instruments
and the underlying assets, risks of default by the other party to certain
transactions, risks that the transactions may incur losses that partially or
completely offset gains in portfolio positions, risks that the transactions may
not be liquid and manager risk. In addition, such transactions may involve
commissions and other costs, which may increase a Portfolio's expenses and
reduce its return. A more complete discussion of options, futures contracts and
related options and their risks is contained in the Statement of Additional
Information.

                  OTHER INVESTMENT PRACTICES AND RISK FACTORS

Although the Portfolios do not intend to engage in substantial short-term
trading, each may sell securities without regard to the length of time they have
been held in order to take advantage of new investment opportunities or when the
Portfolio's management believes the securities potential relative to the
respective Portfolio's investment objective has lessened or otherwise. Each
Portfolio's turnover rate is shown under the heading "Financial Highlights." The
portfolio turnover rate for each Portfolio may be expected to vary from year to
year. A high portfolio turnover rate (100% or more) increases the Portfolio's
transaction costs, including brokerage commissions or dealer costs, and may
result in the realization of more short-term capital gains than if the Portfolio
had lower portfolio turnover. The turnover rate will not be a limiting factor,
however, if

                                       57
<PAGE>   137

the Portfolio's investment adviser considers portfolio changes appropriate.

Further information about these types of investments and other investment
practices that may be used by the Portfolios is contained in the Statement of
Additional Information which can be obtained by investors free of charge as
described on the back cover of this prospectus.

TEMPORARY DEFENSIVE STRATEGY. When market conditions dictate a more "defensive"
investment strategy, each Portfolio may invest on a temporary basis a portion or
all of its assets in securities issued or guaranteed by the U.S. government, its
agencies or instrumentalities, prime commercial paper, certificates of deposit,
bankers' acceptances and other obligations of domestic banks having total assets
of at least $500 million, and repurchase agreements. With respect to the Global
Equity Portfolio, the temporary investments may include comparable securities of
foreign governments, their agencies or instrumentalities; however, during times
of international political or economic uncertainty, all or a portion of the
Portfolio's assets may be in U.S. issuers and denominated in U.S. dollars.
Except with respect to the Money Market Portfolio, the effect of taking a
defensive position may be that such Portfolio does not achieve its investment
objective(s).

Under each advisory agreement, the Portfolio reimburses the Adviser for the cost
of the Portfolio's accounting services, which include maintaining its financial
books and records and calculating its daily net asset value. Other operating
expenses paid by the Portfolio include service fees, distribution fees,
custodial fees, legal and independent accountant fees, the costs of reports and
proxies to shareholders, trustees' fees (other than those who are affiliated
persons of the Adviser, Distributor or Van Kampen Investments) and all other
business expenses not specifically assumed by the Adviser.


For the Global Equity Portfolio and Morgan Stanley Real Estate Securities
Portfolio, the Adviser has entered into subadvisory agreements (the "Subadvisory
Agreements") with the Subadviser to assist the Adviser in performing its
investment advisory functions. Under the Subadvisory Agreements, the Subadviser
receives on an annual basis 50% of the net advisory fees received by the Adviser
with respect to such Portfolios.

The Adviser may utilize at is own expense credit analysis, research and trading
support services provided by its affiliate, Van Kampen Investment Advisory Corp.
("Advisory Corp.").

                          PERSONAL INVESTMENT POLICIES

The Trust, the Adviser and the Subadviser have adopted Codes of Ethics designed
to recognize the fiduciary relationship among the Trust, the Adviser and the
Subadviser and their employees. The Codes permit directors, trustees, officers
and employees to buy and sell securities for their personal accounts subject to
certain restrictions. Persons with access to certain sensitive information are
subject to preclearance and other procedures designed to prevent conflicts of
interest.

                               PURCHASE OF SHARES

The Trust is offering its shares only to Accounts of various insurance companies
to fund the benefits of variable annuity or variable life insurance contracts.
The Trust does not foresee any disadvantage to holders of Contracts arising out
of the fact that the interests of the holders may differ from the interests of
holders of life insurance policies and that holders of one insurance policy may
differ from holders of other insurance policies. Nevertheless, the Trust's
Trustees intend to monitor events in order to identify any material
irreconcilable conflicts which may possibly arise and to determine what action,
if any, should be taken. The Contracts are described in the separate
prospectuses issued by participating insurance companies and accompanying this
Trust's prospectus.


Each Portfolio has adopted a distribution plan (the "Distribution Plan") with
respect to its Class II Shares pursuant to Rule 12b-1 under the 1940 Act. Each
Portfolio also has adopted a service plan (the "Service Plan") with respect to
its Class II Shares. Under the Distribution Plan and the Service Plan, the
Portfolio pays distribution fees in connection with the sale and distribution of
its Class II Shares and service fees in connection with the provision of ongoing
services to shareholders and maintenance of the shareholders' accounts of its
Class II Shares. Under the Distribution Plan and Service Plan, each Portfolio
may spend up to a total of 0.35% per year of such Portfolio's average daily net
assets with respect to the Class II Shares of the Portfolio. Notwithstanding the
foregoing, the Fund's Board of Trustees currently limits the aggregate amount
payable under the Distribution Plan and Service Plan to 0.25% per year of the
Portfolio's average daily net assets with respect to Class II shares of the
Portfolio. From such amount, under the Service Plan, the Portfolio may spend up
to 0.25% per year of the Portfolio's average daily net assets with respect to
the Class II shares of such Portfolio. Because these fees are paid out of the
Portfolio's assets on an ongoing basis, these fees will increase the cost of
your investment in the Portfolio and may cost you more over time than a class of
shares with other types of sales charge arrangements. The net income
attributable to Class II Shares will be reduced by the amount of the
distribution and service fees and other expenses of the Portfolio associated
with such class of shares.


The Trust continuously offers shares in each of the Portfolios to the Accounts
at prices equal to the respective per share net asset value of the Portfolio.
The Distributor, located at 1 Parkview Plaza, PO Box 5555, Oakbrook Terrace,
Illinois 60181-5555, acts as the distributor of the shares. Each of the Trust
and the Distributor reserves the right to refuse any order for the purchase of
shares. Net asset value is determined in the manner set forth below under
"Determination of Net Asset Value."

                        DETERMINATION OF NET ASSET VALUE

Net asset value per share is computed for each Portfolio as of the close of
trading (currently 4:00 p.m., New York time) each day the New York Stock
Exchange is open. See the accompanying prospectus for the policies for
information regarding holidays observed by the insurance company. Net asset
value of each Portfolio is determined by adding the total market value of all
portfolio securities held by the Portfolio, cash and other assets, including
accrued interest. All liabilities, including accrued expenses, of the Portfolio
are subtracted. The resulting amount is divided by the total number of
outstanding shares of the Portfolio to arrive at the net asset value of each
share. See "Determination of Net Asset Value" in the Statement of Additional
Information for further information.

Securities listed or traded on a national securities exchange are valued at the
last sale price. Unlisted securities and listed securities for which the last
sales price is not available are valued at the mean between the last reported
bid and asked prices. U.S. government and agency obligations are valued at the
mean between the last reported bid and asked prices. Listed options are valued
at the last reported sale price on the exchange on which such option is traded
or, if no sales are reported, at the mean between the last reported bid and
asked prices. Private placement securities are valued at the last reported bid
price. Securities for which market quotations are not readily available and
other assets are valued at a fair value in good faith by the Adviser in
accordance with procedures established by the Portfolio's Board of Trustees.
Short-term investments for all Portfolios other than the Money Market Portfolio
are valued as described in the notes to financial statements in the Statement of
Additional Information.

The Money Market Portfolio's assets are valued on the basis of amortized cost,
which involves valuing a

                                       62
<PAGE>   142

portfolio security at its cost, assuming a constant amortization to maturity of
any discount or premium, regardless of the impact of fluctuating interest rates
on the market value of the security. While this method provides certainty in
valuation, it may result in periods in which value as determined by amortized
cost is higher or lower than the price the Portfolio would receive if it sold
the security. During such periods, the yield to investors in the Portfolio may
differ somewhat from that obtained in a similar fund which uses available market
quotations to value all of its portfolio securities.

Trading in securities on many foreign securities exchanges (including European
and Far Eastern securities exchange) and over-the-counter markets is normally
completed before the close of business on each business day in New York (i.e., a
day on which the Exchange is open). In addition, securities trading in a
particular country or countries may not take place on all business days for the
Exchange or may take place on days which are not business days for the Exchange.
Changes in valuations on certain securities may occur at times or on days on
which a Portfolio's net asset value is not calculated and on which a Portfolio
does not effect sales, redemptions and exchanges of its shares. The Portfolio
calculates net asset value per share, and therefore effects sales, redemptions
and exchanges of its shares, as of the close of trading on the Exchange each day
the Exchange is open for trading. Such calculation does not take place
contemporaneously with the determination of the prices of certain foreign
portfolio securities used in such calculation. If events materially affecting
the value of such securities occur between the time when their price is
determined and the time when a Portfolio's net asset value is calculated, such
securities may be valued at fair value as determined in good faith by the
Adviser based in accordance with procedures established by the Trustees.

                              REDEMPTION OF SHARES

Payment for shares tendered for redemption by the insurance company is made
ordinarily in cash within seven days after tender in proper form, except under
unusual circumstances as determined by the SEC. The redemption price will be the
net asset value next determined after the receipt of a request in proper form.
The market values of the securities in each Portfolio are subject to daily
fluctuations and the net asset value per share of each Portfolio's shares will
fluctuate accordingly. Therefore, the redemption value may be more or less than
the investor's cost.

                                   DIVIDENDS,
                                 DISTRIBUTIONS
                                   AND TAXES

All dividends and capital gains distributions of each Portfolio are
automatically reinvested by the Account in additional shares of such Portfolio.

Shares of the Money Market Portfolio and Government Portfolio become entitled to
income distributions declared on the day the shareholder service agent receives
payment of the purchase price in the form of federal funds. Such shares do not
receive income distributions declared on the date of redemption.

DIVIDENDS OF THE MONEY MARKET PORTFOLIO. The Money Market Portfolio declares
income dividends each business day payable monthly. The Money Market Portfolio's
net income for dividend purposes is calculated daily and consists of interest
accrued or discount earned, plus or minus any net realized gains or losses on
portfolio securities, less any amortization of premium and the expenses of the
Money Market Portfolio.

DIVIDENDS AND DISTRIBUTIONS OF THE ASSET ALLOCATION PORTFOLIO, THE COMSTOCK
PORTFOLIO, THE DOMESTIC INCOME PORTFOLIO, THE EMERGING GROWTH PORTFOLIO, THE
ENTERPRISE PORTFOLIO, THE GLOBAL EQUITY PORTFOLIO, THE GOVERNMENT PORTFOLIO, THE
GROWTH AND INCOME PORTFOLIO, THE MORGAN STANLEY REAL ESTATE SECURITIES PORTFOLIO
AND THE STRATEGIC STOCK PORTFOLIO. Dividends from stocks and interest earned
from other investments are the main source of income for these Portfolios.
Substantially all of this income, less expenses, is distributed to Accounts on
an annual basis. When a Portfolio sells portfolio securities, it may realize
capital gains or losses, depending on whether the prices of the securities sold
are higher or lower than the prices the Portfolio paid to purchase them. Net
capital gains represent the excess of net long term capital gains over net
short-term capital losses and any losses carried forward from prior years. Each
of these Portfolios distributes any net capital gains to Accounts no less
frequently than annually.

TAX STATUS OF THE PORTFOLIOS. Each Portfolio has elected to be taxed as a
"regulated investment company" under the Code. By maintaining its qualification
as a "regulated investment company," a Portfolio is not subject to federal
income taxes to the extent it distributes its net investment income and

                                       63
<PAGE>   143

net capital gains. If for any taxable year a Portfolio does not qualify for the
special tax treatment afforded regulated investment companies, all of its
taxable income, including any net capital gains, would be subject to tax at
regular corporate rates (without any deduction for distributions to
shareholders).

TAX TREATMENT TO INSURANCE COMPANY AS SHAREHOLDER. The investments of the
Accounts in the Portfolios are subject to the diversification requirements of
Section 817(h) of the Code, which must be met at the end of each quarter of the
year (or within 30 days thereafter). Regulations issued by the Secretary of the
Treasury have the effect of requiring the Accounts to invest no more than 55% of
their total assets in securities of any one issuer, no more than 70% in the
securities of any two issuers, no more than 80% in the securities of any three
issuers, and no more than 90% in the securities of any four issuers. For this
purpose, the U.S. Treasury and each U.S. Government agency and instrumentality
is considered to be a separate issuer. In the event the investments of the
Accounts in the Portfolios are not properly diversified under Code Section
817(h), then the policies funded by shares of the Portfolios will not be treated
as life insurance for federal income tax purposes and the owners of the policies
will be subject to taxation on their respective shares of the dividends and
distributions paid by the relevant Portfolios.

Dividends paid by each Portfolio from its ordinary income and distributions of
each Portfolio's net short-term capital gains are includable in the insurance
company's gross income. The tax treatment of such dividends and distributions
depends on the insurance company's tax status. To the extent that income of a
Portfolio represents dividends on equity securities rather than interest income,
its distributions are eligible for the 70% dividends received deduction
applicable in the case of a life insurance company as provided in the Code. The
Trust will send to the Accounts a written notice required by the Code
designating the amount and character of any distributions made during such year.

Under the Code, any distributions designated as being made from a Portfolio's
net capital gains are taxable to the insurance company as long-term capital
gains. Such distributions of net capital gains will be designated as capital
gain dividends in a written notice to the Accounts which accompanies the
distribution payments. Capital gain dividends are not eligible for the dividends
received deduction. Ordinary income dividends and capital gain dividends to the
insurance company may also be subject to state and local taxes.

As described in the accompanying prospectus for the Contracts, the insurance
company reserves the right to assess the Account a charge for any taxes paid by
it.

CERTAIN INVESTMENT PRACTICES OF PORTFOLIOS. Certain investment practices of a
Portfolio may be subject to special provisions of the Code that, among other
things, may defer the use of certain losses of the Portfolio and affect the
holding period of the securities held by the Portfolio and the character of the
gains or losses realized by the Portfolio. These provisions may also require the
Portfolio to recognize income or gain without receiving cash with which to make
distributions in the amounts necessary to maintain the Portfolio's qualification
as a regulated investment company and avoid income and excise taxes. Each
Portfolio will monitor its transactions and may make certain tax elections in
order to mitigate the effect of these rules and prevent disqualification of the
Portfolio as a regulated investment company.

                                  APPENDIX --
                                 DESCRIPTION OF
                               SECURITIES RATINGS

STANDARD & POOR'S -- A brief description of the applicable Standard & Poor's
(S&P) rating symbols and their meanings (as published by S&P) follow:

A S&P corporate or municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.

The debt rating is not a recommendation to purchase, sell, or hold a security,
inasmuch as it does not comment as to market price or suitability for a
particular investor.

The ratings are based on current information furnished by the issuer or obtained
by S&P from other sources it considers reliable. S&P does not perform an audit
in connection with any rating and may, on occasion, rely on unaudited financial
information. The ratings may be changed, suspended, or withdrawn as a result of
changes in, or unavailability of, such information, or based on other
circumstances.

The ratings are based, in varying degrees, on the following considerations:

1. Likelihood of payment -- capacity and willingness of the obligor to meet its
   financial commitment on an obligation in accordance with the terms of the
   obligation:

2. Nature of and provisions of the obligation:

3. Protection afforded by, and relative position of, the obligation in the event
   of bankruptcy, reorganization, or other arrangement under the laws of
   bankruptcy and other laws affecting creditor's rights.

                     1. LONG-TERM DEBT -- INVESTMENT GRADE

AAA: Debt rated "AAA" has the highest rating assigned by S&P. Capacity to meet
its financial commitment on the obligation is extremely strong.

AA: Debt rated "AA" differs from the highest rated issues only in small degree.
Capacity to meet its financial commitment on the obligation is very strong.

A: Debt rated "A" is somewhat more susceptible to the adverse effects of changes
in circumstances and economic conditions than obligations in higher rated
categories. Capacity to meet its financial commitment on the obligation is still
strong.

BBB: Debt rated "BBB" exhibits adequate protection parameters. However, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity to meet its financial commitment on the obligation.

                               SPECULATIVE GRADE

BB, B, CCC, CC, C: Debts rated "BB", "B", "CCC", "CC" and "C" are regarded as
having significant speculative characteristics. "BB" indicates the least degree
of speculation and "C" the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.

BB: Debt rated "BB" is less vulnerable to nonpayment than other speculative
issues. However, it faces major ongoing uncertainties or exposure to adverse
business, financial, or economic conditions which could lead to the obligor's
inadequate capacity to meet its financial commitment on the obligation.

B: Debt rated "B" is more vulnerable to nonpayment than obligations rated "BB",
but the obligor currently has the capacity to meet its financial commitment on
the obligation. Adverse business, financial, or economic conditions will likely
impair the obligor's capacity or willingness to meet its financial commitment on
the obligation.

CCC: Debt rated "CCC" is currently vulnerable to nonpayment, and is dependent
upon favorable business, financial, and economic conditions for the obligor to
meet its financial commitment on the obligation. In the event of adverse
business, financial, or economic conditions, the obligor is not likely to have
the capacity to meet its financial commitment on the obligation.

CC: Debt rated "CC" is currently highly vulnerable to nonpayment.

                                      A-1
<PAGE>   145

C: The "C" rating may be used to cover a situation where a bankruptcy petition
has been filed or similar action has been taken, but payments on this obligation
are being continued.

D: Debt rated "D" is in payment default. The "D" rating category is used when
payments on an obligation are not made on the date due even if the applicable
grace period has not expired, unless S&P believes that such payments will be
made during such grace period. The "D" rating also will be used upon the filing
of a bankruptcy petition or the taking of a similar action if payments on an
obligation are jeopardized.

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

r: This symbol is attached to the ratings of instruments with significant
noncredit risks. It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk -- such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

DEBT OBLIGATIONS OF ISSUERS OUTSIDE THE UNITED STATES AND ITS TERRITORIES are
rated on the same basis as domestic corporate and municipal issues. The ratings
measure the creditworthiness of the obligor but do not take into account
currency exchange and related uncertainties.

BOND INVESTMENT QUALITY STANDARDS: Under present commercial bank regulations
issued by the Comptroller of the Currency, bonds rated in the top four
categories ("AAA", "AA", "A", "BBB", commonly known as "investment grade"
ratings) are generally regarded as eligible for bank investment. In addition,
the laws of various states governing legal investments impose certain ratings or
other standards for obligations eligible for investment by savings banks, trust
companies, insurance companies and fiduciaries generally.

                              2. COMMERCIAL PAPER

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

Ratings are graded into several categories, ranging from "A-1" for the highest
quality obligations to "D" for the lowest. These categories are as follows:

A-1: The highest category indicates that the degree of safety regarding timely
payment is strong. Those issues determined to possess extremely strong safety
characteristics are denoted with a plus sign (+) designation.

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

A-3: Issues carrying this designation have adequate capacity for timely payment.
They are, however, more vulnerable to the adverse effects of changes in
circumstances than obligations carrying the higher designations.

B: Issues rated "B" are regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

C: This rating is assigned to short-term debt obligations currently vulnerable
to nonpayment and is dependent upon favorable business, financial, and economic
conditions for the obligor to meet its financial commitment on the obligation.

D: Debt rated "D" is in payment default. The "D" rating category is used when
interest payments or principal payments are not made on the date due, even if
the applicable grace period has not expired, unless S&P believes that such
payments will be made during such grace period. The "D" rating also will be used
upon the filing of a bankruptcy petition or the taking of a similar action if
payments on an obligation are jeopardized.

A commercial paper rating is not a recommendation to purchase, sell or hold a
security inasmuch as it does not comment as to market price or suitability for a
particular investor. The ratings are based on current information furnished to
S&P by the issuer or obtained from other sources it considers reliable. S&P does
not perform an audit in connection with any rating and may, on occasion, rely on
unaudited financial information. The ratings may be changed, suspended or

                                      A-2
<PAGE>   146

withdrawn as a result of changes in, or unavailability of, such information, or
based on other circumstances.

                               3. PREFERRED STOCK

A S&P preferred stock rating is an assessment of the capacity and willingness of
an issuer to pay preferred stock dividends and any applicable sinking fund
obligations. A preferred stock rating differs from a bond rating inasmuch as it
is assigned to an equity issue, which issue is intrinsically different from, and
subordinated to, a debt issue. Therefore, to reflect this difference, the
preferred stock rating symbol will normally not be higher than the bond rating
symbol assigned to, or that would be assigned to, the senior debt of the same
issuer.

The preferred stock ratings are based on the following considerations:

i. Likelihood of payment-capacity and willingness of the issuer to meet the
timely payment of preferred stock dividends and any applicable sinking fund
requirements in accordance with the terms of the obligation.

ii. Nature of, and provisions of, the issuer.

iii. Relative position of the issue in the event of bankruptcy, reorganization,
or other arrangements under the laws of bankruptcy and other laws affecting
creditors' rights.

AAA: This is the highest rating that may be assigned by S&P to a preferred stock
issue and indicates an extremely strong capacity to pay the preferred stock
obligations.

AA: A preferred stock issue rated "AA" also qualifies as a high-quality, fixed
income security. The capacity to pay preferred stock obligations is very strong,
although not as overwhelming as for issues rated "AAA".

A: An issue rated "A" is backed by a sound capacity to pay the preferred stock
obligations, although it is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions.

BBB: An issue rated "BBB" is regarded as backed by an adequate capacity to pay
the preferred stock obligations. Whereas it normally exhibits adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to make payments for a preferred
stock in this category than for issues in the "A" category.

BB, B and CCC: Preferred stock rated "B", "B", and "CCC" are regarded, on
balance, as predominantly speculative with respect to the issuer's capacity to
pay preferred stock obligations.

"BB" indicates the lowest degree of speculation and "CCC" the highest. While
such issues will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions.

CC: The rating "CC" is reserved for a preferred stock issue in arrears on
dividends or sinking fund payments, but that is currently paying.

C: A preferred stock rated "C" is a nonpaying issue.

D: A preferred stock rated "D" is a nonpaying issue with the issuer in default
on debt instruments.

NR: This indicates that no rating has been requested, that there is insufficient
information on which to base a rating, or that S&P does not rate a particular
type of obligation as a matter of policy. PLUS (+) or MINUS (-): To provide more
detailed indications of preferred stock quality, ratings from "AA" to "CCC" may
be modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

A preferred stock rating is not a recommendation to purchase, sell, or hold a
security inasmuch as it does not comment as to market price or suitability for a
particular investor. The ratings are based on current information furnished to
S&P by the issuer or obtained by S&P from other sources it considers reliable.
S&P does not perform an audit in connection with any rating and may, on
occasion, rely on unaudited financial information. The ratings may be changed,
suspended, or withdrawn as a result of changes in, or unavailability of, such
information, or based on other circumstances.

MOODY'S INVESTORS SERVICE  -- a brief description of the applicable Moody's
Investors Service (Moody's) rating symbols and their meanings (as published by
Moody's Investor Service) follows:

                               1. LONG-TERM DEBT

Aaa: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edged." Interest payments are protected by a large or

                                      A-3
<PAGE>   147

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 the Aaa securities.

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

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

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
during both 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 the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long 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 marked 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 to B. The modifier 1 indicates that the issue 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.

ABSENCE OF RATING: Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.

Should no rating be assigned, the reason may be one of the following:

1. An application for rating was not received or accepted.

2. The issue or issuer belongs to a group of securities that are not rated as a
   matter of policy.

3. There is a lack of essential data pertaining to the issue or issuer.

4. The issue was privately placed, in which case the rating is not published in
   Moody's publications.

Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.

                               2. SHORT-TERM DEBT

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

Moody's employs the following three designations, all judged to be investment
grade, to indicate the relative repayment ability of rated issues:

Issuers rated Prime-1 (or supporting institutions) have a superior ability for
repayment of senior short-term debt obligations. Prime-1 repayment ability will
often be evidenced by many of the following characteristics:

- -- Leading market positions in well-established industries.

                                      A-4
<PAGE>   148

- -- High rates of return on funds employed.

- -- Conservative capitalization structure with moderate reliance on debt and
   ample asset protection.

- -- Broad margins is earnings coverage of fixed financial charges and high
   internal cash generation.

- -- Well-established access to a range of financial markets and assured sources
   of alternate liquidity.

Issuers rated Prime-2 (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations. This will normally be evidenced
by many of the characteristics cited above but to a lesser degree. Earnings
trends and coverage ratios, while sound, may be more subject to variation.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternate liquidity is maintained.

Issuers rated Prime-3 (or supporting institutions) have an acceptable ability
for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes of the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

                               3. PREFERRED STOCK

Preferred stock rating symbols and their definitions are as follows:

AAA: As issue which is rated "AAA" is considered to be a top-quality preferred
stock. This rating indicates good asset protection and the least risk of
dividend impairment within the universe of preferred stocks.

AA: An issue which is rated "AA" is considered a high-grade preferred stock.
This rating indicates that there is a reasonable assurance the earnings and
asset protection will remain relatively well maintained in the foreseeable
future.

A: An issue which is rated "A" is considered to be an upper-medium-grade
preferred stock. While risks are judged to be somewhat greater than in the "AAA"
and "AA" classifications, earnings and asset protections are, nevertheless,
expected to be maintained at adequate levels.

BAA: An issue which is rated "BAA" is considered to be a medium-grade preferred
stock, neither highly protected nor poorly secured. Earnings and asset
protection appear adequate at present but may be questionable over any great
length of time.

BA: An issue which is rated "BA" is considered to have speculative elements and
its future cannot be considered well assured. Earnings and asset protection may
be very moderate and not well safeguarded during adverse periods. Uncertainty of
position characterizes preferred stocks in this class.

B: An issue which is rated "B" generally lacks the characteristics of a
desirable investment. Assurance of dividend payments and maintenance of other
terms of the issue over any long period of time may be small.

CAA: An issue which is rated "CAA" is likely to be in arrears on dividend
payments. This rating designation does not purport to indicate the future status
of payments.

CA: An issue which is rated "CA" is speculative in a high degree and is likely
to be in arrears on dividends with little likelihood of eventual payment.

C: This is the lowest rated class of preferred or preference stock. Issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

Moody's applies numerical modifiers 1, 2 and 3 in each rating classification.
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.

GENERAL INFORMATION

     Van Kampen Life Investment Trust, formerly known as Van Kampen American
Capital Life Investment Trust (the "Trust"), was originally organized as a
business trust under the laws of the Commonwealth of Massachusetts on June 3,
1985 under the name American Capital Life Investment Trust. As of September 16,
1995, the Trust was reorganized as a business trust under the laws of the State
of Delaware and changed its name. On July 14, 1998, the Trust adopted its
current name.

     Van Kampen Asset Management Inc. (the "Adviser"), Van Kampen Funds Inc.
(the "Distributor"), and Van Kampen Investor Services Inc. ("Investor Services")
are wholly owned subsidiaries of Van Kampen Investments Inc. ("Van Kampen
Investments"), which is an indirect wholly owned subsidiary of Morgan Stanley
Dean Witter & Co. The principal office of the Fund, the Adviser, the Distributor
and Van Kampen Investments is located at 1 Parkview Plaza, PO Box 5555, Oakbrook
Terrace, Illinois 60181-5555.

     Morgan Stanley Dean Witter & Co. and various of its directly or indirectly
owned subsidiaries, including Morgan Stanley Dean Witter Investment Management
Inc., an investment adviser (the "Subadviser"), Morgan Stanley & Co.
Incorporated, a registered broker-dealer and investment adviser, and Morgan
Stanley International, are engaged in a wide range of financial services. Their
principal businesses include securities underwriting, distribution and trading;
merger, acquisition, restructuring and other corporate finance advisory
activities; merchant banking; stock brokerage and research services; credit
services; asset management; trading of futures, options, foreign exchange,
commodities and swaps (involving foreign exchange, commodities, indices and
interest rates); real estate advice, financing and investing; and global
custody, securities clearance services and securities lending.


     The authorized capitalization of the Trust consists of an unlimited number
of shares of beneficial interest, par value $0.01 per share, which can be
divided into series, such as the Portfolios, and further subdivided into one or
more classes of shares of each series. Each share represents an equal
proportionate interest in the assets of the series with each other share in such
series and no interest in any other series. No series is subject to the
liabilities of any other series. The Declaration of Trust provides that
shareholders are not liable for any liabilities of the Trust or any of its
series, requires inclusion of a clause to that effect in every agreement entered
into by the Trust or any of its series and indemnifies shareholders against any
such liability.



     Each Portfolio currently offers two classes of shares, designated Class I
Shares and Class II Shares. Other classes may be established from time to time
in accordance with provisions of the Declaration of Trust. Each class of shares
of a Portfolio generally are identical in all respects except that each class
bears certain distribution expenses and has exclusive voting rights with respect
to its distribution fee.



     Shares of the Trust entitle their holders to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series and separate votes are taken by each class of a series on matters
affecting an individual class of such series. For example, a change in
investment policy for a series would be voted upon by shareholders of only the
series involved and a change in the distribution fee for a class of a series
would be voted upon by shareholders of only the class of such series involved.
Except as otherwise described in the Prospectus or herein, shares do not have
cumulative voting rights, preemptive rights or any conversion, subscription or
exchange rights.


     The Trust does not contemplate holding regular meetings of shareholders to
elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares may by written request require a meeting to consider the
removal of Trustees by a vote of majority of the shares then outstanding cast in
person or by proxy at such meeting. The Trust will assist such holders in
communicating with other shareholders of the Trust to the extent required by the
Investment Company Act of 1940, as amended (the "1940 Act"), or rules or
regulations promulgated by the Securities and Exchange Commission ("SEC").

     The Trustees may amend the Declaration of Trust (including with respect to
any series) in any manner without shareholder approval, except that the Trustees
may not adopt any amendment adversely affecting the rights of shareholders of
any series without approval by a majority of the shares of each affected series
present at a meeting of shareholders (or such higher vote as may be required by
the 1940 Act or other applicable law) and except that the Trustees cannot amend
the Declaration of Trust to impose any liability on shareholders,

                                       B-2

make any assessment on shares or impose liabilities on the Trustees without
approval from each affected shareholder or Trustee, as the case may be.

     Statements contained in this Statement of Additional Information as to the
contents of any contract or other document referred to are not necessarily
complete, and, in each instance, reference is made to the copy of such contract
or other document filed as an exhibit to the Registration Statement of which
this Statement of Additional Information forms a part, each such statement being
qualified in all respects by such reference.


     As of April   , 2000, no person was known by the Trust to own beneficially
or to hold of record 5% or more of the outstanding Class I Shares or Class II
Shares of any portfolio except as set forth below. The Trust offers its shares
only to separate accounts of various insurance companies. Those separate
accounts have authority to vote shares from which they have not received
instructions from the Contract Owners, but only in the same proportion with
respect to "yes" votes, "no" votes or abstentions as is the case with respect to
shares for which instructions were received.

                              INVESTMENT PRACTICES

     The following disclosures supplement disclosures set forth in the
prospectus and do not, standing alone, present a complete or accurate
explanation of the matters disclosed. Readers must refer also to this caption in
the prospectus for a complete presentation of the matters disclosed below.

FOREIGN SECURITIES

     The Portfolios also may purchase foreign securities in the form of American
Depositary Receipts ("ADRs") and European Depositary Receipts ("EDRs") or other
securities representing underlying shares of foreign companies. These securities
may not necessarily be denominated in the same currency as the underlying
securities but generally are denominated in the currency of the market in which
they are traded. ADRs are receipts typically issued by an American bank or trust
company which evidence ownership of underlying securities issued by a foreign
corporation. ADRs are publicly traded on exchanges or over-the-counter in the
United States and are issued through "sponsored" or "unsponsored" arrangements.
In a

                                       B-6
<PAGE>   157

sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some
or all of the depositary's transaction fees, whereas under an unsponsored
arrangement, the foreign issuer assumes no obligations and the depositary's
transaction fees are paid by the ADR holders. In addition, less information
generally is available for an unsponsored ADR than about a sponsored ADR and
financial information about a company may not be as reliable for an unsponsored
ADR as it is for a sponsored ADR. The Portfolios may invest in ADRs through both
sponsored and unsponsored arrangements. EDRs are receipts issued in Europe by
banks or depositaries which evidence similar ownership arrangement.

DURATION

     Duration is a measure of the expected life of a debt security that was
developed as an alternative to the concept of "term to maturity." Duration
incorporates a debt security's yield, coupon interest payments, final maturity
and call features into one measure. Traditionally a debt security's "term to
maturity" has been used as a proxy for the sensitivity of the security's price
to changes in interest rates. However, "term to maturity" measures only the time
until a debt security provides its final payment taking no account of the
pattern of the security's payments of interest or principal prior to maturity.
Duration is a measure of the expected life of a debt security on a present value
basis expressed in years. It measures the length of the time interval between
the present and the time when the interest and principal payments are scheduled
(or in the case of a callable bond, expected to be received), weighing them by
the present value of the cash to be received at each future point in time. For
any debt security with interest payments occurring prior to the payment of
principal, duration is always less than maturity, and for zero coupon issues,
duration and term to maturity are equal. In general, the lower the coupon rate
of interest or the longer the maturity, or the lower the yield-to-maturity of a
debt security, the longer its duration; conversely, the higher the coupon rate
of interest, the shorter the maturity or the higher the yield-to-maturity of a
debt security, the shorter its duration. There are some situations where even
the standard duration calculation does not properly reflect the interest rate
exposure of a security. For example, floating and variable rate securities often
have final maturities of ten or more years; however, their interest rate
exposure corresponds to the frequency of the coupon reset. Another example where
the interest rate exposure is not properly captured by duration is the case of
mortgage pass-through securities. The stated final maturity of such securities
is generally 30 years, but current prepayment rates are more critical in
determining the securities' interest rate exposure. In these and other similar
situations, the Adviser will use more sophisticated analytical techniques that
incorporate the economic life of a security into the determination of its
interest rate exposure.

MORTGAGE-RELATED SECURITIES

     The Government Portfolio invests in mortgage-related securities.
Mortgage-related securities may be issued or guaranteed by an agency or
instrumentality of the U.S. government, but not necessarily by the U.S.
government itself. One type of mortgage-related security is a Government
National Mortgage Association ("GNMA") Certificate which is backed as to
principal and interest by the full faith and credit of the U.S. government.
Another type of mortgage-related security is a Federal National Mortgage
Association ("FNMA") Certificate. Principal and interest payments of FNMA
Certificates are guaranteed only by FNMA itself, not by the full faith and
credit of the U.S. government. A third type of mortgage-related security is a
Federal Home Loan Mortgage Association ("FHLMC") Participation Certificate. This
type of security is backed by FHLMC as to payment of principal and interest but,
like a FNMA security, it is not backed by the full faith and credit of the U.S.
government.

GNMA Certificates

     Government National Mortgage Association.  The Government National Mortgage
Association is a wholly owned corporate instrumentality of the United States
within the U.S. Department of Housing and Urban Development. GNMA's principal
programs involve its guarantees of privately issued securities backed by pools
of mortgages.

                                       B-7
<PAGE>   158

     Nature of GNMA Certificates.  GNMA Certificates are mortgage-backed
securities. The Certificates evidence part ownership of a pool of mortgage
loans. The Certificates which the Fund purchases are of the modified
pass-through type. Modified pass-through Certificates entitle the holder to
receive all interest and principal payments owned on the mortgage pool, net of
fees paid to the GNMA Certificate issuer and GNMA, regardless of whether or not
the mortgagor actually makes the payment.

     GNMA Certificates are backed by mortgages and, unlike most bonds, their
principal amount is paid back by the borrower over the length of the loan rather
than in a lump sum at maturity. Principal payments received by the Portfolio
will be reinvested in additional GNMA Certificates or in other permissible
investments.

     GNMA Guarantee.  The National Housing Act authorizes GNMA to guarantee the
timely payment of principal and interest on securities backed by a pool of
mortgages insured by the Federal Housing Administration ("FHA") or the Farmers
Home Administration or guaranteed by the Veterans Administration ("VA"). The
GNMA guarantee is backed by the full faith and credit of the United States. GNMA
is also empowered to borrow without limitation from the U.S. Treasury if
necessary to make any payments required under its guarantee.

     Life of GNMA Certificates.  The average life of a GNMA Certificate is
likely to be substantially less than the original maturity of the mortgage pools
underlying the securities. Prepayments of principal by mortgagors and mortgage
foreclosures will result in the return of a portion of principal invested before
the maturity of the mortgages in the pool.

     As prepayment rates of individual mortgage pools will vary widely, it is
not possible to predict accurately the average life of a particular issue of
GNMA Certificates. However, statistics published by the FHA are normally used as
an indicator of the expected average life of GNMA Certificates. These statistics
indicate that the average life of single-family dwelling mortgages with 25-30
year maturities (the type of mortgages backing the vast majority of GNMA
Certificates) is approximately twelve years. For this reason, it is customary
for pricing purposes to consider GNMA Certificates as 30-year mortgage-backed
securities which prepay fully in the twelfth year.

     Yield Characteristics of GNMA Certificates.  The coupon rate of interest of
GNMA Certificates is lower than the interest rate paid on the VA-guaranteed or
FHA-insured mortgages underlying the Certificates, but only by the amount of the
fees paid to GNMA and the GNMA Certificate issuer.

     The coupon rate by itself, however, does not indicate the yield which will
be earned on the Certificates for the following reasons:

     1. Certificates are usually issued at a premium or discount, rather than at
        par.

     2. After issuance, Certificates usually trade in the secondary market at a
        premium or discount.

     3. Interest is paid monthly rather than semi-annually as is the case for
        traditional bonds. Monthly compounding has the effect of raising the
        effective yield earned on GNMA Certificates.

     4. The actual yield of each GNMA Certificate is influenced by the
        prepayment experience of the mortgage pool underlying the Certificate.
        If mortgagors prepay their mortgages, the principal returned to
        Certificate holders may be reinvested at higher or lower rates.

     In quoting yields for GNMA Certificates, the customary practice is to
assume that the Certificates will have a twelve-year life. Compared on this
basis, GNMA Certificates have historically yielded roughly 1/4 of 1.00% more
than high grade corporate bonds and 1/2 of 1.00% more than U.S. government and
U.S. government agency bonds. As the life of individual pools may vary widely,
however, the actual yield earned on any issue of GNMA Certificates may differ
significantly from the yield estimated on the assumption of a twelve-year life.

     Market for GNMA Certificates.  Since the inception of the GNMA
mortgage-backed securities program in 1970, the amount of GNMA Certificates
outstanding has grown rapidly. The size of the market and the

                                       B-8
<PAGE>   159

active participation in the secondary market by securities dealers and many
types of investors make GNMA Certificates highly liquid instruments. Quotes for
GNMA Certificates are readily available from securities dealers and depend on,
among other things, the level of market rates, the Certificate's coupon rate and
the prepayment experience of the pool of mortgages backing each Certificate.

FNMA Securities

     The Federal National Mortgage Association ("FNMA") was established in 1938
to create a secondary market in mortgages insured by the FHA. FNMA issues
guaranteed mortgage pass-through certificates ("FNMA Certificates"). FNMA
Certificates resemble GNMA Certificates in that each FNMA Certificate represents
a pro rata share of all principal and interest payments made and owed on the
underlying pool. FNMA guarantees timely payment of interest and principal on
FNMA Certificates. The FNMA guarantee is not backed by the full faith and credit
of the United States.

FHLMC Securities

     The Federal Home Loan Mortgage Corporation ("FHLMC") was created in 1970 to
promote development of a nationwide secondary market in conventional residential
mortgages. The FHLMC issues two types of mortgage pass-through securities
("FHLMC Certificates"): mortgage participation certificates ("PCs") and
guaranteed mortgage certificates ("GMCs"). PCs resemble GNMA Certificates in
that each PC represents a pro rata share of all interest and principal payments
made and owed on the underlying pool. The FHLMC guarantees timely monthly
payment of interest on PCs and the ultimate payment of principal. GMCs also
represent a pro rata interest in a pool of mortgages. However, these instruments
pay interest semi-annually and return principal once a year in guaranteed
minimum payments. The expected average life of these securities is approximately
ten years. The FHLMC guarantee is not backed by the full faith and credit of the
United States.

COLLATERALIZED MORTGAGE OBLIGATIONS

     The Government Portfolio may invest in collateralized mortgage obligations.
Collateralized mortgage obligations are debt obligations issued generally by
agencies or instrumentalities of the U.S. Government, or by private originators
of, or investors in, mortgages which are secured by mortgage-related securities,
including GNMA Certificates, FHLMC Certificates and FNMA Certificates, together
with certain funds and other collateral. Scheduled distributions on the
mortgage-related securities pledged to secure the collateralized mortgage
obligations, together with certain funds and other collateral and reinvestment
income thereon at an assumed reinvestment rate, will be sufficient to make
timely payments of interest on the obligations and to retire the obligations not
later than their stated maturity. Since the rate of payment of principal of any
collateralized mortgage obligation will depend on the rate of payment (including
prepayments) of the principal of the mortgage loans underlying the
mortgage-related securities, the actual maturity of the obligation could occur
significantly earlier than its stated maturity. Collateralized mortgage
obligations may be subject to redemption under certain circumstances. The rate
of interest borne by collateralized mortgage obligations may be either fixed or
floating. In addition, certain collateralized mortgage obligations do not bear
interest and are sold at a substantial discount (i.e., a price less than the
principal amount). Purchases of collateralized mortgage obligations at a
substantial discount involves a risk that the anticipated yield on the purchase
may not be realized if the underlying mortgage loans prepay at a slower than
anticipated rate, since the yield depends significantly on the rate of
prepayment of the underlying mortgages. Conversely, purchases of collateralized
mortgage obligations at a premium involve additional risk of loss of principal
in the event of unanticipated prepayments of the mortgage loans underlying the
mortgage-related securities since the premium may not have been fully amortized
at the time the obligation is repaid. The market value of collateralized
mortgage obligations purchased at a substantial premium of discount is extremely
volatile and the effects of prepayments on the underlying mortgage loans may
increase such volatility.

                                       B-9
<PAGE>   160

     Although payment of the principal and interest on the mortgage-backed
certificates pledged to secure collateralized mortgage obligations may be
guaranteed by GNMA, FHLMC or FNMA, the collateralized mortgage obligations
represent obligations solely of their issuers and generally are not insured or
guaranteed by GNMA, FHLMC, FNMA or any other governmental agency or
instrumentality, or by any other person or entity. The issuers of collateralized
mortgage obligations typically have no significant assets other than those
pledged as collateral for the obligations.

LENDING OF SECURITIES

     Consistent with applicable regulatory requirements and applicable
investment restrictions, certain Portfolios may lend portfolio securities to
broker-dealers and other financial institutions provided that such loans are
callable at any time by the Portfolio, and are at all times secured by cash
collateral that is at least equal to the market value, determined daily, of the
loaned securities. The advantage of such loans is that the Portfolio continues
to receive the interest on the loaned securities, while at the same time earning
interest on the collateral which will be invested in short-term obligations. The
Portfolio pays lending fees and custodial fees in connection with loans of its
securities. There is no assurance as to the extent to which securities loans can
be effected.

     A loan may be terminated by the borrower on one business day's notice or by
the Portfolio at any time. If the borrower fails to maintain the requisite
amount of collateral, the loan automatically terminates, and the Portfolio could
use the collateral to replace the securities while holding the borrower liable
for any excess of replacement cost over collateral. As with any extensions of
credit, there are risks of delay in recovery and in some cases even loss of
rights in the collateral should the borrower of the securities fail financially.
However, these loans of portfolio securities will only be made to firms deemed
by the Adviser to be creditworthy and when the consideration which can be earned
from such loans is believed to justify the attendant risks. On termination of
the loan, the borrower is required to return the securities to the Portfolio;
any gain or loss in the market price during the loan would inure to the
Portfolio.

     When voting or consent rights which accompany loaned securities pass to the
borrower, the Portfolio will follow the policy of calling the loan, whole or in
part as may be appropriate, to permit the exercise of such rights if the matters
involved would have a material effect on the Portfolio's investment in the
securities which are the subject of the loan.

FORWARD COMMITMENTS

     Each of the Government Portfolio, Domestic Income Portfolio and Morgan
Stanley Real Estate Securities Portfolio may purchase or sell securities on a
"when-issued" or "delayed-delivery" basis ("Forward Commitments"). These
transactions occur when securities are purchased or sold by the Portfolio with
payment and delivery taking place in the future, frequently a month or more
after such transaction. The price is fixed on the date of the commitment, and
the seller continues to accrue interest on the securities covered by the Forward
Commitment until delivery and payment takes place. At the time of settlement,
the market value of the securities may be more or less than the purchase or sale
price. The Portfolio may either settle a Forward Commitment by taking delivery
of the securities or may either resell or repurchase a Forward Commitment on or
before the settlement date in which event the Portfolio may reinvest the
proceeds in another Forward Commitment.

     Relative to a Forward Commitment purchase, the Portfolio maintains a
segregated account (which is marked-to-market daily) of cash or liquid
securities (which may have maturities which are longer than the term of the
Forward Commitment) with the Portfolio's custodian in an aggregate amount equal
to the amount of its commitment as long as the obligation to purchase continues.
Since the market value of both the securities subject to the Forward Commitment
and the securities held in the segregated account may fluctuate, the use of
Forward Commitments may magnify the impact of interest rate changes on the
Portfolio's net asset value.

                                      B-10
<PAGE>   161

     A Forward Commitment sale is covered if the Portfolio owns or has the right
to acquire the underlying securities subject to the Forward Commitment. A
Forward Commitment sale is for cross-hedging purposes if it is not covered, but
is designed to provide a hedge against a decline in value of a security or
currency which the Portfolio owns or has the right to acquire. Only the
Government Portfolio and the Real Estate Securities Portfolio may engage in
forward commitment transactions for cross-hedging purposes. In either
circumstance, the Portfolio maintains in a segregated account (which is marked
to market daily) either the security covered by the Forward Commitment or cash
or liquid securities with the Portfolio's custodian in an aggregate amount equal
to the amount of its commitment as long as the obligation to sell continues. By
entering into a Forward Commitment sale transaction, the Portfolio foregoes or
reduces the potential for both gain and loss in the security which is being
hedged by the Forward Commitment sale.

     When engaging in Forward Commitments, the Fund relies on the other party to
complete the transaction. Should the other party fail to do so, the Fund might
lose a purchase or sale opportunity that could be more advantageous than
alternative opportunities at the time of the failure. Forward Commitments are
not traded on an exchange and thus may be less liquid than exchange traded
contracts.

INTEREST RATE TRANSACTIONS

     The Government Portfolio may enter into interest rate swaps and may
purchase or sell interest rate caps, floors and collars. The Portfolio expects
to enter into these transactions primarily to preserve a return or spread on a
particular investment or portion of its portfolio. The Portfolio may also enter
into these transactions to protect against any increase in the price of
securities the Portfolio anticipates purchasing at a later date. The Portfolio
does not intend to use these transactions as speculative investments and will
not enter into interest rate swaps or sell interest rate caps or floors where it
does not own or have the right to acquire the underlying securities or other
instruments providing the income stream the Portfolio may be obligated to pay.
Interest rate swaps involve the exchange by the Portfolio with another party of
their respective commitments to pay or receive interest, e.g., an exchange of
floating rate payments for fixed-rate payments. The purchase of an interest rate
cap entitles the purchaser, to the extent that a specified index exceeds a
predetermined interest rate, to receive payments of interest on a
contractually-based principal amount from the party selling the interest rate
cap. The purchase of an interest rate floor entitles the purchaser, to the
extent that a specified index falls below a predetermined interest rate, to
receive payments of interest on a contractually-based principal amount from the
party selling the interest rate floor. An interest rate collar combines the
elements of purchasing a cap and selling a floor. The collar protects against an
interest rate rise above the maximum amount but foregoes the benefit of an
interest rate decline below the minimum amount. Interest rate swaps, caps,
floors and collars may be treated as illiquid securities and be subject to the
Portfolio's investment restriction limiting investment in illiquid securities.

     The Portfolio may enter into interest rate swaps, caps, floors and collars
on either an asset-based or liability-based basis, and will usually enter into
interest rate swaps on a net basis, i.e., the two payment streams are netted
out, with the Portfolio receiving or paying, as the case may be, only the net
amount of the two payments. The net amount of the excess, if any, of the
Portfolio's obligations over its entitlements with respect to each interest rate
swap will be accrued on a daily basis and an amount of cash or liquid securities
having an aggregate net asset value at least equal to the accrued excess will be
maintained in a segregated account by the Portfolio's custodian. If the
Portfolio enters into an interest rate swap on other than a net basis, the
Portfolio would maintain a segregated account in the full amount accrued on a
daily basis of the Portfolio's obligations with respect to the swap. Interest
rate transactions do not constitute senior securities under the 1940 Act when
the Portfolio segregates assets to cover the obligations under the transactions.
The Portfolio will enter into interest rate swap, cap or floor transactions only
with counterparties approved by the Trustees. The Adviser will monitor the
creditworthiness of counterparties to its interest rate swap, cap, floor and
collar transactions on an ongoing basis. If there is a default by the other
party to such a transaction, the Portfolio will have contractual remedies
pursuant to the agreements related to the transaction. To the extent the
Portfolio sells (i.e., writes) caps, floors and collars, it will maintain in a
segregated account cash or liquid securities having an aggregate net asset value
at least equal to the full amount, accrued on a daily basis, of the Portfolio's
net

                                      B-11
<PAGE>   162

obligations with respect to the caps, floors or collars. The use of interest
rate swaps is a highly specialized activity which involves investment techniques
and risks different from those associated with ordinary portfolio securities
transactions. If the Adviser is incorrect in its forecasts of the market values,
interest rates and other applicable factors, the investment performance of the
Portfolio would diminish compared with what it would have been if these
investment techniques were not used. The use of interest rate swaps, caps,
collars and floors may also have the effect of shifting the recognition of
income between current and future periods.

     These transactions do not involve the delivery of securities or other
underlying assets or principal. Accordingly, the risk of loss with respect to
interest rate swaps is limited to the net amount of interest payments that the
Portfolio is contractually obligated to make. If the other party to an interest
rate swap defaults, the Portfolio's risk of loss consists of the net amount of
interest payments that the Portfolio contractually is entitled to receive.

PORTFOLIO TURNOVER

     A Portfolio's turnover rate is calculated by dividing the lesser of
purchases or sales of portfolio securities for a fiscal year by the average
monthly value of the Portfolio's portfolio securities during such fiscal year.
The turnover rate may vary greatly from year to year as well as within a year. A
Portfolio's portfolio turnover rate (the lesser of the value of the securities
purchased or securities sold divided by the average value of the securities held
in the Portfolio's portfolio excluding all securities whose maturities at
acquisition were one year or less) is shown in the table of "Financial
Highlights" in the Prospectus. A high portfolio turnover rate (100% or more)
increases the Portfolio's transaction costs, including brokerage commissions,
and may result in the realization of more short-term capital gains than if the
Portfolio had a lower portfolio turnover. The turnover rate will not be a
limiting factor, however, if the Adviser deems portfolio changes appropriate.

ILLIQUID SECURITIES

     Each Portfolio, subject to its investment restrictions, may invest a
portion of its assets in illiquid securities, which includes securities that are
not readily marketable, repurchase agreements which have a maturity of longer
than seven days and generally includes securities that are restricted from sale
to the public without registration under the Securities Act of 1933, as amended
(the "1933 Act"). The sale of such securities often requires more time and
results in higher brokerage charges or dealer discounts and other selling
expenses than does the sale of liquid securities trading on national securities
exchanges or in over-the-counter markets. Restricted securities are often
purchased at a discount from the market price of unrestricted securities of the
same issuer reflecting the fact that such securities may not be readily
marketable without some time delay. Investments in securities which have no
ready market are valued at fair value as determined in good faith by the Adviser
in accordance with procedures approved by the Portfolio's Trustees. Ordinarily,
the Portfolio would invest in restricted securities only when it receives the
issuer's commitment to register the securities without expense to the Portfolio.
However, registration and underwriting expenses (which may range from 7% to 15%
of the gross proceeds of the securities sold) may be paid by the Portfolio.
Restricted securities which can be offered and sold to qualified institutional
buyers under Rule 144A under the 1933 Act ("144A Securities") and are determined
to be liquid under guidelines adopted by and subject to the supervision of the
Portfolio's Board of Trustees are not subject to the limitation on illiquid
securities. Such 144A Securities are subject to monitoring and may become
illiquid to the extent qualified institutional buyers become, for a time,
uninterested in purchasing such securities. Factors used to determine whether
144A Securities are liquid include, among other things, a security's trading
history, the availability of reliable pricing information, the number of dealers
making quotes or making a market in such security and the number of potential
purchasers in the market for such security. For purposes hereof, investments by
the Portfolio in securities of other investment companies will not be considered
investments in restricted securities to the extent permitted by (i) the 1940
Act, as amended from time to time, (ii) the rules and regulations promulgated by
the SEC under the 1940 Act, as amended from time to time, or (iii) an exemption
or other relief from the provisions of the 1940 Act.

MONEY MARKET PORTFOLIO

     The Money Market Portfolio seeks to maintain a net asset value of $1.00 per
share. To do so, the Portfolio uses the amortized cost method of valuing the
Portfolio's securities pursuant to Rule 2a-7 under the 1940 Act, certain
requirements of which are summarized below.

     In accordance with Rule 2a-7, the Portfolio is required to maintain a
dollar-weighted average portfolio maturity of 90 days or less, purchase only
instruments having remaining maturities of thirteen months or less and invest
only in U.S. dollar denominated securities determined in accordance with
procedures established by the Trustees to present minimal credit risks and which
are rated in one of the two highest rating categories for debt obligations by at
least two nationally recognized statistical rating organizations (or one rating
organization if the instrument was rated by only one such organization) or, if
unrated, are of comparable quality as determined in accordance with procedures
established by the Trustees. The nationally recognized statistical rating
organizations currently rating instruments of the type the Portfolio may
purchase are Moody's Investors Service, Inc., Standard & Poor's, Fitch Investors
Services, Inc., Duff and Phelps, Inc. and IBCA Limited and IBCA Inc.

     In addition, the Portfolio will not invest more than 5% of its total assets
in the securities (including the securities collateralizing a repurchase
agreement) of, or subject to puts issued by, a single issuer, except that (i)
the Portfolio may invest more than 5% of its total assets in a single issuer for
a period of up to three business days in certain limited circumstances, (ii) the
Portfolio may invest in obligations issued or guaranteed by the U.S. government
without any such limitation, and (iii) the limitation with respect to puts does
not apply to unconditional puts if no more than 10% of the Portfolio's total
assets is invested in securities issued or guaranteed by the issuer of the
unconditional put. Investments in rated securities not rated in the highest
category by at least two rating organizations (or one rating organization if the
instrument was rated by only one such organization), and unrated securities not
determined by the Trustees to be comparable to those rated in the highest
category, will be limited to 5% of the Portfolio's total assets, with the
investment in any one such issuer being limited to no more than the greater of
one percent of the Portfolio's total assets or $1,000,000. As to each security,
these percentages are measured at the time the Portfolio purchases the security.
There can be no assurance that the Portfolio will be able to maintain a stable
net asset value of $1.00 per share.

STRATEGIC STOCK PORTFOLIO

     The Strategic Stock Portfolio invests primarily in dividend paying equity
securities of companies included in the DJIA or in the MSCI USA Index. In
selecting securities for the Portfolio, the Adviser presently intends to follow
the following procedures, subject to and limited by the Portfolio's other
investment policies and restrictions.

     The Portfolio will reflect on its books twelve separate sub-accounts (each
a "Strategic Sub-Account"). Strategic Sub-Accounts will be successively
designated Strategic Sub-Account 1 through Strategic Sub-Account 12.

     As of the close of business on (i) the business day immediately prior to
the Portfolio's commencement of investment operations and (ii) the last business
day of each month thereafter (each a "Strategic Determination Date"), the
Adviser will identify 20 securities pursuant to the Strategic Selection Policies
discussed in the Prospectus (the "Current Period Strategic Securities").

     As of commencement of investment operations, the Portfolio invested the
assets of Strategic Sub-Account 1 approximately equally in each of the Current
Period Strategic Securities determined on the first Strategic Determination
Date. This resulted in approximately 5% of the Portfolio's assets being invested
in each of the initial Current Period Strategic Securities. On each of the
eleven subsequent Strategic Determination Dates, the Adviser invested the cash
available for investment due to the sale of new shares and the receipt of
dividend and interest income in the next successive Strategic Sub-Account
approximately equally in each of the Current Period Strategic Securities for
that Strategic Determination Date. Following

                                      B-13
<PAGE>   164

the twelfth Strategic Determination Date the assets of one Strategic Sub-Account
will be evaluated and adjusted each month so that the assets of each Strategic
Sub-Account will be reviewed and adjusted once every 12 months.

     Consistent with the Portfolio's investment objective, the Adviser may
modify these procedures without prior notice to investors to adjust the
frequency of portfolio review and adjustment and to adjust the portion of the
Portfolio's assets that is reviewed and adjusted during each period.

     The following disclosures supplement disclosures set forth in the
Prospectus. Readers must refer also to the Prospectus for a complete
presentation.

OPTIONS, FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

     All of the Portfolios except the Domestic Income Portfolio and the Money
Market Portfolio may engage in transactions in options, futures contracts and
options on futures contracts. Set forth below is certain additional information
regarding options, futures contracts and options on futures contracts. See the
Prospectus for further information.

WRITING CALL AND PUT OPTIONS

     Purpose. Options may be utilized to hedge various market or to obtain,
through receipt of premiums, a greater current return than would be realized on
the underlying securities alone. The Portfolio's current return can be expected
to fluctuate because premiums earned from an option writing program and dividend
or interest income yields on portfolio securities vary as economic and market
conditions change. Writing options on portfolio securities also is likely to
result in a higher portfolio turnover.

     Writing Options. The purchaser of a call option pays a premium to the
writer (i.e., the seller) for the right to buy the underlying security from the
writer at a specified price during a certain period. Each Portfolio writes call
options only on a covered basis and only the Government Portfolio and Comstock
Portfolio write call options either on a covered basis or for cross-hedging
purposes. A call option is covered if at all times during the option period the
Portfolio owns or has the right to acquire securities of the type that it would
be obligated to deliver if any outstanding option were exercised. Thus, the
Government Portfolio may write options on mortgage-related or other U.S.
Government securities or forward commitments of such securities. An option is
for cross-hedging purposes if it is not covered, but is designed to provide a
hedge against a security which a Portfolio owns or has the right to acquire. In
such circumstances, a Portfolio collateralizes the option by maintaining in a
segregated account with a Portfolio's custodian, cash or liquid securities in an
amount not less than the market value of the underlying security, marked to
market daily, while the option is outstanding.

     The purchaser of a put option pays a premium to the writer (i.e., the
seller) for the right to sell the underlying security to the writer at a
specified price during a certain period. A Portfolio would write put options
only on a secured basis, which means that, at all times during the option
period, the Portfolio would maintain in a segregated account with its custodian
cash or liquid securities in an amount of not less than the exercise price of
the option, or would hold a put on the same underlying security at an equal or
greater exercise price.

     Closing Purchase Transactions and Offsetting Transactions. In order to
terminate its position as a writer of a call or put option, a Portfolio could
enter into a "closing purchase transaction," which is the purchase of a call
(put) on the same underlying security and having the same exercise price and
expiration date as the call (put) previously written by the Portfolio. The
Portfolio would realize a gain (loss) if the premium plus commission paid in the
closing purchase transaction is less (greater) than the premium it received on
the sale of the option. A Portfolio would also realize a gain if an option it
has written lapses unexercised.

     A Portfolio could write options that are listed on an exchange as well as
options which are privately negotiated in over-the-counter transactions. A
Portfolio could close out its position as writer of an option only

                                      B-14
<PAGE>   165

if a liquid secondary market exists for options of that series, but there is no
assurance that such a market will exist, particularly in the case of
over-the-counter options, since they can be closed out only with the other party
to the transaction. Alternatively, a Portfolio could purchase an offsetting
option, which would not close out its position as a writer, but would provide an
asset of equal value to its obligation under the option written. The Portfolios
will only enter into over-the-counter options (other than currency options) that
are subject to a buy-back provision permitting the Fund to require the
counterparty to close out the option at a formula price within seven days. If a
Portfolio is not able to enter into a closing purchase transaction or to
purchase an offsetting option with respect to an option it has written, it will
be required to maintain the securities subject to the call or the collateral
underlying the put until a closing purchase transaction can be entered into (or
the option is exercised or expires), even though it might not be advantageous to
do so. Such options may be considered illiquid and subject to a Portfolio's
limitation on illiquid securities.

     The exercise price of call options may be below ("in-the-money"), equal to
("at-the-money"), or above ("out-of-the-money") the current market value of the
underlying securities or futures contracts at the time the options are written.
The converse applies to put options.

     Risks of Writing Options. By writing a call option, a Portfolio loses the
potential for gain on the underlying security above the exercise price while the
option is outstanding; by writing a put option a Portfolio might become
obligated to purchase the underlying security at an exercise price that exceeds
the then current market price.

PURCHASING CALL AND PUT OPTIONS

     A Portfolio could purchase call options to protect (i.e., hedge) against
anticipated increases in the prices of securities it wishes to acquire. In
addition, the Comstock Portfolio, the Emerging Growth Portfolio, the Enterprise
Portfolio, the Growth and Income Portfolio, the Real Estate Securities Portfolio
and the Strategic Stock Portfolio may purchase call options for capital
appreciation. Since the premium paid for a call option is typically a small
fraction of the price of the underlying security, a given amount of funds will
purchase call options covering a much larger quantity of such security than
could be purchased directly. By purchasing call options, a Portfolio could
benefit from any significant increase in the price of the underlying security to
a greater extent than had it invested the same amount in the security directly.
However, because of the very high volatility of option premiums, a Portfolio
would bear a significant risk of losing the entire premium if the price of the
underlying security did not rise sufficiently, or if it did not do so before the
option expired.

     Put options may be purchased to protect (i.e., hedge) against anticipated
declines in the market value of either specific portfolio securities or of a
Portfolio's assets generally. In addition, the Comstock Portfolio, the Emerging
Growth Portfolio, the Enterprise Portfolio, the Growth and Income Portfolio, the
Real Estate Securities Portfolio and the Strategic Stock Portfolio may purchase
put options for capital appreciation in anticipation of a price decline in the
underlying security and a corresponding increase in the value of the put option.
The purchase of put options for capital appreciation involves the same
significant risk of loss as described above for call options.

     In any case, the purchase of options for capital appreciation would
increase a Portfolio's volatility by increasing the impact of changes in the
market price of the underlying securities on the Portfolio's net asset value.

     The Government Portfolio will not purchase call or put options on
securities if as a result, more than ten percent of its net assets would be
invested in premiums on such options.

     A Portfolio may purchase either listed or over-the-counter options.

RISK FACTORS APPLICABLE TO OPTIONS ON U.S. GOVERNMENT SECURITIES

     Treasury Bonds and Notes. Because trading interest in options written on
Treasury bonds and notes tends to center on the most recently auctioned issues,
the exchanges will not continue indefinitely to introduce options with new
expirations to replace expiring options on particular issues. Instead, the
expirations

                                      B-15
<PAGE>   166

introduced at the commencement of options trading on a particular issue will be
allowed to run their course, with the possible addition of a limited number of
new expirations as the original ones expire. Options trading on each issue of
bonds or notes will thus be phased out as new options are listed on more recent
issues, and options representing a full range of expirations will not ordinarily
be available for every issue on which options are traded.

     Treasury Bills. Because the deliverable Treasury bill changes from week to
week, writers of Treasury bill calls cannot provide in advance for their
potential exercise settlement obligations by acquiring and holding the
underlying security. However, if the Portfolio holds a long position in Treasury
bills with a principal amount of the securities deliverable upon exercise of the
option, the position may be hedged from a risk standpoint by the writing of a
call option. For so long as the call option is outstanding, the Portfolio will
hold the Treasury bills in a segregated account with its custodian so that it
will be treated as being covered.

     Mortgage-Related Securities. The following special considerations will be
applicable to options on mortgage-related securities. Currently such options are
only traded over-the-counter. Since the remaining principal balance of a
mortgage-related security declines each month as a result of mortgage payments,
the Portfolio as a writer of a mortgage-related call holding mortgage-related
securities as "cover" to satisfy its delivery obligation in the event of
exercise may find that the mortgage-related securities it holds no longer have a
sufficient remaining principal balance for this purpose. Should this occur, the
Portfolio will purchase additional mortgage-related securities from the same
pool (if obtainable) or replacement mortgage-related securities in the cash
market in order to maintain its cover. A mortgage-related security held by the
Portfolio to cover an option position in any but the nearest expiration month
may cease to represent cover for the option in the event of a decline in the
coupon rate at which new pools are originated under the FHA/VA loan ceiling in
effect at any given time. If this should occur, the Portfolio will no longer be
covered, and the Portfolio will either enter into a closing purchase transaction
or replace such mortgage-related security with a mortgage-related security which
represents cover. When the Portfolio closes its position or replaces such
mortgage-related security, it may realize an unanticipated loss and incur
transaction costs.

OPTIONS ON STOCK INDEXES (ASSET ALLOCATION PORTFOLIO, COMSTOCK PORTFOLIO,
EMERGING GROWTH PORTFOLIO, ENTERPRISE PORTFOLIO, GLOBAL EQUITY PORTFOLIO, GROWTH
AND INCOME PORTFOLIO, REAL ESTATE SECURITIES PORTFOLIO AND STRATEGIC STOCK
PORTFOLIO ONLY)

     Options on stock indexes are similar to options on stock, but the delivery
requirements are different. Instead of giving the right to take or make delivery
of stock at a specified price, an option on a stock index gives the holder the
right to receive an amount of cash which amount will depend upon the closing
level of the stock index upon which the option is based being greater than (in
the case of a call) or less than (in the case of a put) the exercise price of
the option. The amount of cash received will be the difference between the
closing price of the index and the exercise price of the option, multiplied by a
specified dollar multiple. The writer of the option is obligated, in return for
the premium received, to make delivery of this amount.

     Some stock index options are based on a broad market index such as the
Standard & Poor's 500 or the New York Stock Exchange Composite Index, or a
narrower index such as the Standard & Poor's 100. Indices are also based on an
industry or market segment such as the AMEX Oil and Gas Index or the Computer
and Business Equipment Index. A stock index fluctuates with changes in the
market values of the stocks included in the index. Options are currently traded
on The Chicago Board Options Exchange, the American Stock Exchange and other
exchanges.

     Gain or loss to a Portfolio on transactions in stock index options will
depend on price movements in the stock market generally (or in a particular
industry or segment of the market) rather than price movements of individual
securities. As with stock options, the Portfolio may offset its position in
stock index options prior to expiration by entering into a closing transaction
on an exchange, or it may let the option expire unexercised.

                                      B-16
<PAGE>   167

FOREIGN CURRENCY OPTIONS

     Certain Portfolios may purchase put and call options on foreign currencies
to reduce the risk of currency exchange fluctuation. Premiums paid for such put
and call options will be limited to no more than five percent of the Portfolio's
net assets at any given time. Options on foreign currencies operate similarly to
options on securities, and are traded primarily in the over-the-counter market,
although options on foreign currencies are traded on United States and foreign
exchanges. Exchange-traded options are expected to be purchased by the Portfolio
from time to time and over-the-counter options may also be purchased, but only
when the Adviser believes that a liquid secondary market exists for such
options, although there can be no assurance that a liquid secondary market will
exist for a particular option at any specific time. Options on foreign
currencies are affected by all of those factors which influence foreign exchange
rates and investment generally. See "Investment Practices -- Using Options,
Futures Contracts and Options on Futures Contracts" in the Prospectus.

     The value of a foreign currency option is dependent upon the value of the
underlying foreign currency relative to the U.S. dollar. As a result, the price
of the option position may vary with changes in the value of either or both
currencies and has no relationship to the investment merits of a foreign
security. Because foreign currency transactions occurring in the interbank
market (conducted directly between currency traders, usually large commercial
banks, and their customers) involve substantially larger amounts than those that
may be involved in the use of foreign currency options, investors may be
disadvantaged by having to deal in an odd lot market (generally consisting of
transactions of less than $1 million) for the underlying foreign currencies at
prices that are less favorable than for round lots.

     There is no systematic reporting of last sale information for foreign
currencies and there is no regulatory requirement that quotations available
through dealers or other market sources be firm or revised on a timely basis.
Quotation information available is generally representative of very large
transactions in the interbank market and thus may not reflect relatively smaller
transactions (i.e., less than $1 million) where rates may be less favorable. The
interbank market in foreign currencies is a global, around-the-clock market. To
the extent that the U.S. options markets are closed while the markets for the
underlying currencies remain open, significant price and rate movements may take
place in the underlying markets that cannot be reflected in the options markets.

FUTURES CONTRACTS

     Certain Portfolios may engage in transactions involving futures contracts
and related options in accordance with rules and interpretations of the
Commodity Futures Trading Commission ("CFTC") under which the Trust and its
Portfolios would be exempt from registration as a "commodity pool."

     Types of Contracts. An interest rate futures contract is an agreement
pursuant to which a party agrees to take or make delivery of a specified debt
security (such as U.S. Treasury bonds, U.S. Treasury notes, U.S. Treasury bills
and GNMA Certificates) at a specified future time and at a specified price.
Interest rate futures contracts also include cash settlement contracts based
upon a specified interest rate such as the London interbank offering rate for
dollar deposits, LIBOR.

     A stock index futures contract is an agreement pursuant to which a party
agrees to take or make delivery of cash equal to a specified dollar amount times
the difference between the stock index value at a specified time and the price
at which the futures contract is originally struck. No physical delivery of the
underlying stocks in the index is made. Currently, stock index futures contracts
can be purchased with respect to several indices on various exchanges.
Differences in the stocks included in the indexes may result in differences in
correlation of the futures contracts with movements in the value of the
securities being hedged.

     A Portfolio also may invest in foreign stock index futures traded outside
the United States which involve additional risks, including fluctuations in
foreign exchange rates, future foreign political and economic developments, and
the possible imposition of exchange controls or other foreign or United States
governmental laws or restrictions applicable to such investments.

     Initial and Variation Margin. In contrast to the purchase or sale of a
security, no price is paid or received upon the purchase or sale of a futures
contract. Initially, a Portfolio is required to deposit with its custodian in an
account in the broker's name an amount of cash or liquid securities equal to a
percentage (which will normally range between 2% and 10%) of the contract
amount. This amount is known as initial margin. The nature of initial margin in
futures transactions is different from that of margin in securities transactions
in that futures contract margin does not involve the borrowing of funds by the
customer to finance the transaction. Rather, the initial margin is in the nature
of a performance bond or good faith deposit on the contract, which is returned
to the Portfolio upon termination of the futures contract and satisfaction of
its contractual obligations. Subsequent payments to and from the broker, called
variation margin, are made on a daily basis as the price of the underlying
securities or index fluctuates, making the long and short positions in the
futures contract more or less valuable, a process known as marking to market.

     For example, when a Portfolio purchases a futures contract and the price of
the underlying security or index rises, that position increases in value, and
the Portfolio receives from the broker a variation margin payment equal to that
increase in value. Conversely, where the Portfolio purchases a futures contract
and the value of the underlying security or index declines, the position is less
valuable, and the Portfolio is required to make a variation margin payment to
the broker.

     At any time prior to expiration of the futures contract, the Portfolio may
elect to terminate the position by taking an opposite position. A final
determination of variation margin is then made, additional cash is required to
be paid by or released to the Portfolio, and the Portfolio realizes a loss or a
gain.

     Futures Strategies. When a Portfolio anticipates a significant market or
market sector advance, the purchase of a futures contract affords a hedge
against not participating in the advance at a time when the Portfolio is
otherwise fully invested ("anticipatory hedge"). Such purchase of a futures
contract serves as a temporary substitute for the purchase of individual
securities, which may be purchased in an orderly fashion once the market has
stabilized. As individual securities are purchased, an equivalent amount of
futures contracts could be terminated by offsetting sales. A Portfolio may sell
futures contracts in anticipation of or in a general market or market sector
decline that may adversely affect the market value of the Portfolio's securities
("defensive hedge"). To the extent that the Portfolio's portfolio of securities
changes in value in correlation with the underlying security or index, the sale
of futures contracts substantially reduces the risk to a Portfolio of a market
decline and, by so doing, provides an alternative to the liquidation of
securities positions in the Portfolio with attendant transaction costs.
Ordinarily commissions on futures transactions are lower than transaction costs
incurred in the purchase and sale of securities.

     Special Risks Associated with Futures Transactions. There are several risks
connected with the use of futures contracts as a hedging device. These include
the risk of imperfect correlation between movements in the price of the futures
contracts and of the underlying securities, the risk of market distortion, the
illiquidity risk and the risk of error in anticipating price movement.

     There may be an imperfect correlation (or no correlation) between movements
in the price of the futures contracts and of the securities being hedged. The
risk of imperfect correlation increases as the composition of the securities
being hedged diverges from the securities upon which the futures contract is
based. If the price of the futures contract moves less than the price of the
securities being hedged, the hedge will not be fully effective. To compensate
for this imperfect correlation, a Portfolio could buy or sell futures contracts
in a greater dollar amount than the dollar amount of securities being hedged if
the historical volatility of the securities being hedged is greater than the
historical volatility of the securities underlying the futures contract.
Conversely, a Portfolio could buy or sell futures contracts in a lesser dollar
amount than the dollar amount of the securities being hedged if the historical
volatility of the securities being hedged is less than the historical volatility
of the securities underlying the futures contract. It is also possible that the
value of futures contracts held by a Portfolio could decline at the same time as
portfolio securities being hedged; if this occurred, the Portfolio would lose
money on the futures contract in addition to suffering a decline in value in the
portfolio securities being hedged.

                                      B-18
<PAGE>   169

     There is also the risk that the price of futures contracts may not
correlate perfectly with movements in the securities, currency or index
underlying the futures contract due to certain market distortions. First, all
participants in the futures market are subject to margin depository and
maintenance requirements. Rather than meet additional margin depositary
requirements, investors may close futures contracts through offsetting
transactions, which could distort the normal relationship between the futures
market and the securities or index underlying the futures contract. Second, from
the point of view of speculators, the deposit requirements in the futures market
are less onerous than margin requirements in the securities markets. Therefore,
increased participation by speculators in the futures markets may cause
temporary price distortions. Due to the possibility of price distortion in the
futures markets and because of the imperfect correlation between movements in
futures contracts and movements in the securities underlying them, a correct
forecast of general market trends by the Adviser may still not result in a
successful hedging transaction.

     There is also the risk that futures markets may not be sufficiently liquid.
Futures contracts may be closed out only on an exchange or board of trade that
provides a market for such futures contracts. Although a Portfolio intends to
purchase or sell futures only on exchanges and boards of trade where there
appears to be an active secondary market, there can be no assurance that an
active secondary market will exist for any particular contract or at any
particular time. In the event of such illiquidity, it might not be possible to
close a futures position and, in the event of adverse price movement, a
Portfolio would continue to be required to make daily payments of variation
margin. Since the securities being hedged would not be sold until the related
futures contract is sold, an increase, if any, in the price of the securities
may to some extent offset losses on the related futures contract. In such event,
the Portfolio would lose the benefit of the appreciation in value of the
securities.

     Successful use of futures is also subject to the Advisers' ability
correctly to predict the direction of movements in the market. For example, if
the Portfolio hedges against a decline in the market, and market prices instead
advance, the Portfolio will lose part or all of the benefit of the increase in
value of its securities holdings because it will have offsetting losses in
futures contracts. In such cases, if the Portfolio has insufficient cash, it may
have to sell portfolio securities at a time when it is disadvantageous to do so
in order to meet the daily variation margin.

     Although the Portfolio intends to enter into futures contracts only if
there is an active market for such contracts, there is no assurance that an
active market will exist for the contracts at any particular time. Most U.S.
futures exchanges and boards of trade limit the amount of fluctuation permitted
in futures contract prices during a single trading day. Once the daily limit has
been reached in a particular contract, no trades may be made that day at a price
beyond that limit. It is possible that futures contract prices would move to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of futures positions and subjecting some
futures traders to substantial losses. In such event, and in the event of
adverse price movements, the Portfolio would be required to make daily cash
payments of variation margin. In such circumstances, an increase in the value of
the portion of the portfolio being hedged, if any, may partially or completely
offset losses on the futures contract. However, there is no guarantee that the
price of the securities being hedged will, in fact, correlate with the price
movements in a futures contract and thus provide an offset to losses on the
futures contract.

     A Portfolio will not enter into a futures contract or option (except for
closing transactions) for other than for bona fide hedging purposes if,
immediately thereafter, the sum of the amount of its initial margin and premiums
on open futures contracts and options would exceed 5% of the Portfolio's total
assets (taken at current value); however, in the case of an option that is
in-the-money at the time of the purchase, the in-the-money amount may be
excluded in calculating the 5% limitation. Certain state securities laws to
which a Portfolio may be subject may further restrict the Portfolio's ability to
engage in transactions in futures contracts and related options. In order to
prevent leverage in connection with the purchase of futures contracts by a
Portfolio, an amount of cash or liquid securities equal to the market value of
the obligation under the futures contracts (less any related margin deposits)
will be maintained in a segregated account with the custodian.

OPTIONS ON FUTURES CONTRACTS

     A Portfolio could also purchase and write options on futures contracts. An
option on a futures contract gives the purchaser the right, in return for the
premium paid, to assume a position in a futures contract (a long position if the
option is a call and a short position if the option is a put) at a specified
exercise price at any time during the option period. As a writer of an option on
a futures contract, a Portfolio is subject to initial margin and maintenance
requirements similar to those applicable to futures contracts. In addition, net
option premiums received by a Portfolio are required to be included as initial
margin deposits. When an option on a futures contract is exercised, delivery of
the futures position is accompanied by cash representing the difference between
the current market price of the futures contract and the exercise price of the
option. A Portfolio could purchase put options on futures contracts in lieu of,
and for the same purposes as the sale of a futures contract; at the same time,
it could write put options at a lower strike price (a "put bear spread") to
offset part of the cost of the strategy to the Portfolio. The purchase of call
options on futures contracts is intended to serve the same purpose as the actual
purchase of the futures contract.

     Risks of Transactions in Options on Futures Contracts. In addition to the
risks described above which apply to all options transactions, there are several
special risks relating to options on futures. The Adviser will not purchase
options on futures on any exchange unless, in the Adviser's opinion, a liquid
secondary exchange market for such options exists. Compared to the use of
futures, the purchase of options on futures involves less potential risk to a
Portfolio because the maximum amount at risk is the premium paid for the options
(plus transaction costs). However there may be circumstances, such as when there
is no movement in the level of the index, when the use of an option on a future
would result in a loss to the Portfolio when the use of a future would not.

ADDITIONAL RISKS OF OPTIONS AND FUTURES TRANSACTIONS

     Each of the exchanges has established limitations governing the maximum
number of call or put options on the same underlying security or futures
contract (whether or not covered) which may be sold by a single investor,
whether acting alone or in concert with others (regardless of whether such
options are written on the same or different exchanges or are held or written on
one or more accounts or through one or more brokers). Option positions of all
investment companies advised by the Adviser are combined for purposes of these
limits. An exchange may order the liquidation of positions found to be in
violation of these limits and it may impose other sanctions or restrictions.
These position limits may restrict the number of listed options which the
Portfolio may write.

     In the event of the bankruptcy of a broker through which a Portfolio
engages in transactions in options, futures or related options, the Portfolio
could experience delays or losses in liquidating open positions purchased or
incur a loss of all or part of its margin deposits with the broker. Transactions
are entered into by a Portfolio only with brokers or financial institutions
deemed creditworthy by the Adviser.

ADDITIONAL RISKS OF OPTIONS ON FUTURES CONTRACTS, FORWARD CONTRACTS AND OPTIONS
ON FOREIGN CURRENCIES

     Unlike transactions entered into by a Portfolio in futures contracts,
options on foreign currencies and forward contracts are not traded on contract
markets regulated by the CFTC or (with the exception of certain foreign currency
options) by the Securities and Exchange Commission ("SEC"). To the contrary,
such instruments are traded through financial institutions acting as
market-makers, although foreign currency options are also traded on certain
national securities exchanges, such as the Philadelphia Stock Exchange and the
Chicago Board Options Exchange, subject to SEC regulation. Similarly, options on
currencies may be traded over-the-counter. In an over-the-counter trading
environment, many of the protections afforded to exchange participants will not
be available. For example, there are no daily price fluctuation limits, and
adverse market movements could, therefore, continue to an unlimited extent over
a period of time. Although the purchaser of an option cannot lose more than the
amount of the premium plus related transaction costs, this entire amount could
be lost. Moreover, the option seller and a trader of forward contracts could
lose amounts substantially in excess of their initial investments, due to the
margin and collateral requirements associated with such positions.

                                      B-20
<PAGE>   171

     Options on foreign currencies traded on national securities exchanges are
within the jurisdiction of the SEC, as are other securities traded on such
exchanges. As a result, many of the protections provided to traders on organized
exchanges will be available with respect to such transactions. In particular,
all foreign currency option positions entered into on a national securities
exchange are cleared and guaranteed by the Options Clearing Corporation ("OCC"),
thereby reducing the risk of counterparty default. Further, a liquid secondary
market in options traded on a national securities exchange may be more readily
available than in the over-the-counter market, potentially permitting the
Portfolio to liquidate open positions at a profit prior to exercise or
expiration, or to limit losses in the event of adverse market movements.

     The purchase and sale of exchange-traded foreign currency options, however,
is subject to the risks of the availability of a liquid secondary market
described above, as well as the risks regarding adverse market movements,
margining of options written, the nature of the foreign currency market,
possible intervention by governmental authorities and the effects of other
political and economic events. In addition, exchange-traded options on foreign
currencies involve certain risks not presented by the over-the-counter market.
For example, exercise and settlement of such options must be made exclusively
through the OCC, which has established banking relationships in applicable
foreign countries for this purpose. As a result, the OCC may, if it determines
that foreign governmental restrictions or taxes would prevent the orderly
settlement of foreign special procedures on exercise and settlement, such as
technical changes in the mechanics of delivery of currency, the fixing of dollar
settlement prices or prohibitions, on exercise.

     In addition, futures contracts, options on futures contracts, forward
contracts and options on foreign currencies may be traded on foreign exchanges.
Such transactions are subject to the risk of governmental actions affecting
trading in or the prices of foreign currencies or securities. The value of such
positions also could be adversely affected by (i) other complex foreign
political and economic factors, (ii) lesser availability than in the United
States of data on which to make trading decisions, (iii) delays in the
Portfolio's ability to act upon economic events occurring in foreign markets
during nonbusiness hours in the United States, (iv) the imposition of different
exercise and settlement terms and procedures and margin requirements than in the
United States, and (v) lesser trading volume.

INVESTMENT RESTRICTIONS

     Each Portfolio has adopted the following restrictions which may not be
changed without approval by the vote of a majority of its outstanding voting
shares; which is defined by the 1940 Act as the lesser of (i) 67% or more of the
voting securities present at a meeting, if the holders of more than 50% of the
outstanding voting securities of the Portfolio are present or represented by
proxy; or (ii) more than 50% of the Portfolio's outstanding voting securities.
The percentage limitations need only be met at the time the investment is made
or after relevant action is taken. The Portfolios are subject to the
restrictions set forth below. (Those restrictions that are only applicable to
certain Portfolios are noted as such.)

THE FOLLOWING RESTRICTIONS ARE APPLICABLE TO THE ASSET ALLOCATION PORTFOLIO, THE
DOMESTIC INCOME PORTFOLIO, THE EMERGING GROWTH PORTFOLIO, THE ENTERPRISE
PORTFOLIO, THE GLOBAL EQUITY PORTFOLIO, THE GOVERNMENT PORTFOLIO, THE GROWTH AND
INCOME PORTFOLIO AND THE MONEY MARKET PORTFOLIO:

A Portfolio shall not:

      1. Invest in securities of any company if any officer or trustee of the
         Portfolio or of the Adviser owns more than 1/2 of 1% of the outstanding
         securities of such company, and such officers and trustees own more
         than 5% of the outstanding securities of such issuer;

      2. Invest in companies for the purpose of acquiring control or management
         thereof except that the Portfolio may purchase securities of other

<PAGE>   172

      3. Underwrite securities of other companies, except insofar as a Portfolio

         of 1933 in the resale of any securities owned by the Portfolio; or

      4. Lend its portfolio securities in excess of 10% of its total assets,
         both taken at market value provided that any loans shall be in
         accordance with the guidelines established for such loans by the Board
         of Trustees of the Trust as described under "Investment
         Practices--Lending of Securities" including the maintenance of
         collateral from the borrower equal at all times to the current market
         value of the securities loaned.

         THE FOLLOWING ADDITIONAL RESTRICTIONS ARE APPLICABLE TO THE ASSET
         ALLOCATION PORTFOLIO AND THE ENTERPRISE PORTFOLIO:

A Portfolio shall not:

     1. With respect to 75% of its assets, invest more than 5% of its assets in
        the securities of any one issuer (except obligations of the United
        States Government, its agencies or instrumentalities and repurchase
        agreements secured thereby) or purchase more than 10% of the outstanding
        voting securities of any one issuer except that the Portfolio may
        purchase securities of other investment companies to the extent
        permitted by (i) the 1940 Act, as amended from time to time, (ii) the
        rules and regulations promulgated by the SEC under the 1940 Act, as
        amended from time to time, or (iii) an exemption or other relief from
        the provisions of the 1940 Act;

     2. Invest in securities issued by other investment companies except as part

        extent permitted by (i) the 1940 Act, as amended from time to time, (ii)
        the rules and regulations promulgated by the SEC under the 1940 Act, as
        amended from time to time, or (iii) an exemption or other relief from
        the provisions of the 1940 Act;

     3. Make any investment in real estate, commodities or commodities
        contracts, except that the Portfolio may enter into transactions in
        options, futures contracts or options on futures contracts and may
        purchase securities secured by real estate or interests therein; or
        issued by companies, including real estate investment trusts, which
        invest in real estate or interests therein;

     4. Invest in interests in oil, gas, or other mineral exploration or
        development programs;

     5. Purchase a restricted security or a security for which market quotations
        are not readily available if as a result of such purchase more than 5%
        of the Portfolio's assets would be invested in such securities except
        that the Portfolio may purchase securities of other investment companies
        to the extent permitted by (i) the 1940 Act, as amended from time to
        time, (ii) the rules and regulations promulgated by the SEC under the
        1940 Act, as amended from time to time, or (iii) an exemption or other
        relief from the provisions of the 1940 Act;

     6. Lend money, except that a Portfolio may invest in repurchase agreements
        in accordance with applicable requirements set forth in the Prospectus
        and may acquire debt securities which the Portfolio's investment
        policies permit. A Portfolio will not invest in repurchase agreements
        maturing in more than seven days (unless subject to a demand feature) if
        any such investment, together with any illiquid securities (including
        securities which are subject to legal or contractual restrictions on
        resale) held by the Portfolio, exceeds 10% of the market or other fair
        value of its total net assets; provided, however, that this limitation
        excludes shares of other open-end investment companies owned by the
        Portfolio but includes the Portfolio's pro rata portion of the
        securities and other assets owned by any such investment company. See
        "Repurchase Agreements" in the Prospectus;

     7. Invest more than 25% of the value of its total assets in securities of
        issuers in any particular industry (except obligations of the United
        States Government, its agencies or instrumentalities and repurchase
        agreements secured thereby); provided, however, that this limitation
        excludes shares of

                                      B-22
<PAGE>   173

        other open-end investment companies owned by the Portfolio but includes
        the Portfolio's pro rata portion of the securities and other assets
        owned by any such investment company;

     8. Make short sales of securities, unless at the time of the sale the
        Portfolio owns or has the right to acquire an equal amount of such
        securities. Notwithstanding the foregoing, the Portfolio may engage in
        transactions in options, futures contracts and options on futures
        contracts;

     9. Purchase securities on margin, except that a Portfolio may obtain such
        short-term credits as may be necessary for the clearance of purchases
        and sales of securities. The deposit or payment by the Portfolio of
        initial or maintenance margin in connection with transactions in
        options, futures contracts or options on futures contracts is not
        considered the purchase of a security on margin;

     10. Invest more than 5% of its assets in companies having a record,
         together with predecessors, of less than three years continuous
         operation except that the Portfolio may purchase securities of other
         investment companies to the extent permitted by (i) the 1940 Act, as
         amended from time to time, (ii) the rules and regulations promulgated
         by the SEC under the 1940 Act, as amended from time to time, or (iii)
         an exemption or other relief from the provisions of the 1940 Act; or

     11. Borrow in excess of 10% of the market or other fair value of its total
         assets, or pledge its assets to an extent greater than 5% of the market
         or other fair value of its total assets. Any such borrowings shall be
         from banks and shall be undertaken only as a temporary measure for
         extraordinary or emergency purposes. Deposits in escrow in connection
         with the writing of covered call or secured put options, or in
         connection with the purchase or sale of futures contracts and related
         options are not deemed or to be a pledge or other encumbrance.

     In addition, the following restrictions apply to, and may not be changed
without the approval of the holders of a majority of the shares of, the
Portfolio indicated:

          The Enterprise Portfolio may not invest more than 5% of its net assets
     in warrants or rights valued at the lower of cost or market, nor more than
     2% of its net assets in warrants or rights (valued on such basis) which are
     not listed on the New York or American Stock Exchanges. Warrants or rights
     acquired in units or attached to other securities are not subject to the
     foregoing limitation. Furthermore, the Enterprise Portfolio may not invest
     in the securities of a foreign issuer if, at the time of acquisition, more
     than 10% of the value of the Enterprise Portfolio's total assets would be
     invested in such securities. Foreign investments may be subject to special
     risks, including future political and economic developments, the possible
     imposition of additional withholding taxes on dividend or interest income
     payable on the securities, or the seizure or nationalization of companies,
     or establishment of exchange controls or adoption of other restrictions
     which might adversely affect the investment.

          The Asset Allocation Portfolio may not invest in the securities of a
     foreign issuer if, at the time of acquisition, more than 25% of the value
     of the Asset Allocation Portfolio's total assets would be invested in such
     securities.

THE FOLLOWING ADDITIONAL RESTRICTIONS ARE APPLICABLE TO THE DOMESTIC INCOME
PORTFOLIO:

The Domestic Income Portfolio shall not:

      1. With respect to 75% of its assets, invest more than 5% of its assets in
         the securities of any one issuer (except obligations of the United
         States Government, its agencies or instrumentalities and repurchase
         agreements secured thereby) or purchase more than 10% of the
         outstanding voting securities of any one issuer except that the
         Portfolio may purchase securities of other investment companies to the
         extent permitted by (i) the 1940 Act, as amended from time to time,
         (ii) the rules and regulations promulgated by the SEC under the 1940
         Act, as amended from time to time, or (iii) an exemption or other
         relief from the provisions of the 1940 Act;

                                      B-23
<PAGE>   174

      2. Invest in securities issued by other investment companies except as
         part of a merger, reorganization or other acquisition and except to the
         extent permitted by (i) the 1940 Act, as amended from time to time,
         (ii) the rules and regulations promulgated by the SEC under the 1940
         Act, as amended from time to time, or (iii) an exemption or other
         relief from the provisions of the 1940 Act;

      3. Make any investment in real estate, commodities or commodities
         contracts, except that the Portfolio may purchase securities secured by
         real estate or interests therein; or issued by companies, including
         real estate investment trusts, which invest in real estate or interests
         therein;

      4. Invest in interests in oil, gas, or other mineral exploration or
         development programs;

      5. Purchase a restricted security or a security for which market
         quotations are not readily available if as a result of such purchase
         more than 5% of the Portfolio's assets would be invested in such
         securities except that the Portfolio may purchase securities of other
         investment companies to the extent permitted by (i) the 1940 Act, as
         amended from time to time, (ii) the rules and regulations promulgated
         by the SEC under the 1940 Act, as amended from time to time, or (iii)
         an exemption or other relief from the provisions of the 1940 Act;

        of the Portfolio's assets would be invested in such securities except
        that the Fund may purchase securities of other investment companies to
        the extent permitted by (i) the 1940 Act, as amended from time to time,
        (ii) the rules and regulations promulgated by the SEC under the 1940
        Act, as amended from time to time, or (iii) an exemption or other relief
        from the provisions of the 1940 Act;

     6. Lend money, except that the Portfolio may invest in repurchase
        agreements in accordance with applicable requirements set forth in the
        Prospectus and may acquire debt securities which the Portfolio's
        investment policies permit. The Portfolio will not invest in repurchase
        agreements maturing in more than seven days (unless subject to a demand
        feature) if any such investment, together with any illiquid securities
        (including securities which are subject to legal or contractual
        restrictions on resale) held by the Portfolio, exceeds ten percent of
        the market or other fair value of its total net assets. See "Repurchase
        Agreements" in the Prospectus;

     7. Invest more than 25% of the value of its total assets in securities of
        issuers in any particular industry (except obligations of the United
        States Government, its agencies or instrumentalities and repurchase

     8. Make short sales of securities, unless at the time of the sale the
        Portfolio owns or has the right to acquire an equal amount of such
        securities. Notwithstanding the foregoing, the Portfolio may make short
        sales by entering into forward commitments for hedging or cross-hedging
        purposes and the Portfolio may engage in transactions in options, future
        contracts and related options;

     9. Purchase securities on margin, except that the Portfolio may obtain such
        short-term credits as may be necessary for the clearance of purchases
        and sales of securities. The deposit or payment by the Portfolio of
        initial or maintenance margin in connection with interest rate futures
        contracts or related options transactions is not considered the purchase
        of a security on margin;

     10. Invest more than 5% of its assets in companies having a record,
         together with predecessors, of less than three years continuous
         operation except that the Portfolio may purchase securities of other
         investment companies to the extent permitted by (i) the 1940 Act, as
         amended from time to time, (ii) the rules and regulations promulgated
         by the SEC under the 1940 Act, as amended from time to time, or (iii)
         an exemption or other relief from the provisions of the 1940 Act;

     11. Borrow in excess of 10% of the market or other fair value of its total
         assets, or pledge its assets to an extent greater than 5% of the market
         or other fair value of its total assets. Any such borrowings shall be
         from banks and shall be undertaken only as a temporary measure for
         extraordinary or emergency purposes. Deposits in escrow in connection
         with the writing of options, or in connection with the purchase or sale
         of futures contracts and related options are not deemed to be a pledge
         or other encumbrance; or

     12. Write, purchase or sell puts, calls or combinations thereof, except
         that the Portfolio may (a) write covered or fully collateralized call
         options, write secured put options, and enter into closing or
         offsetting purchase transactions with respect to such options, (b)
         purchase options to the extent that the premiums paid for all such
         options owned at any time do not exceed 10% of its total assets, and
         enter into closing or offsetting transactions with respect to such
         options, and (c) engage in transactions in interest rate futures
         contracts and related options provided that such transactions are
         entered into for bona fide hedging purposes (or that the underlying
         commodity value of the
                                      B-30
<PAGE>   181

         Portfolio's long positions do not exceed the sum of certain identified
         liquid investments as specified in CFTC regulations), provided further
         that the aggregate initial margin and premiums do not exceed 5% of the
         fair market value of the Portfolio's total assets, and provided further
         that the Portfolio may not purchase futures contracts or related
         options if more than 30% of the Portfolio's total assets would be so
         invested.

PORTFOLIO:

The Growth and Income Portfolio shall not:

     1. Borrow money, except from a bank and then only as a temporary measure
        for extraordinary or emergency purposes but not for making additional
        investments and not in excess of 5% of the total net assets of the
        Portfolio taken at cost. In connection with any borrowing the Portfolio
        may pledge up to 15% of its total assets taken at cost. Notwithstanding
        the foregoing, the Portfolio may engage in transactions in options,
        futures contracts and related options, segregate or deposit assets to
        cover or secure options written, and make margin deposits or payments

        options.

     4. Issue senior securities, as defined in the 1940 Act, except that this
        restriction shall not be deemed to prohibit the Portfolio from (i)
        making and collateralizing any permitted borrowings, (ii) making any
        permitted loans of its portfolio securities, or (iii) entering into
        repurchase agreements, utilizing options, futures contracts, options on
        futures contracts and other investment strategies and instruments that
        would be considered "senior securities" but for the maintenance by the
        Portfolio of a segregated account with its custodian or some other form
        of "cover."

     5. Invest more than 25% of its total net asset value in any one industry
        provided, however, that this limitation excludes shares of other
        open-end investment companies owned by the Portfolio but includes the
        Portfolio's pro rata portion of the securities and other assets owned by
        any such company.

     6. Invest more than 5% of the market value of its total assets at the time
        of purchase in the securities (except U.S. Government securities) of any
        one issuer or purchase more than 10% of the outstanding voting
        securities of such issuer except that the Portfolio may purchase
        securities of other investment companies to the extent permitted by (i)
        the 1940 Act, as amended from time to time, (ii) the rules and
        regulations promulgated by the SEC under the 1940 Act, as amended from

        of the 1940 Act.

     In addition to the foregoing fundamental policies which may not be changed
without shareholder approval, the Growth and Income Portfolio is subject to the
following policies which may be amended by the Trustees.

     1. Purchase securities on margin, or sell securities short, but the
        Portfolio may enter into transactions in options, futures contracts and
        related options and may make margin deposits and payments in connection
        therewith.

     2. The Portfolio may not invest in interests in oil, gas, or other mineral
        exploration or development programs, except that the Portfolio may
        acquire securities of public companies which themselves are engaged in
        such activities.

     3. Purchase securities of a corporation in which a trustee of the Portfolio
        owns a controlling interest.

<PAGE>   182

     4. Permit officers or trustees of the Portfolio to profit by selling
        securities to or buying them from the Portfolio. However, companies with

        securities to, and purchase securities from the Portfolio when acting as
        broker or dealer at the customary and usual rates and discounts, to the
        extent permitted by the 1940 Act.

        portion of an issue of publicly distributed debt securities shall not be
        considered the making of a loan.

        investment companies to the extent permitted by (i) the 1940 Act, as
        amended from time to time, (ii) the rules and regulations promulgated by
        the SEC under the 1940 Act, as amended from time to time, or (iii) an
        exemption or other relief from the provisions of the 1940 Act.

        having a record together with predecessors of less than three years
        continuous operation and in securities not having readily available

        other investment companies to the extent permitted by (i) the 1940 Act,
        as amended from time to time, (ii) the rules and regulations promulgated
        by the SEC under the 1940 Act, as amended from time to time, or (iii) an

     1. The Portfolio may not make investments for the purpose of exercising
        control or management although the Portfolio retains the right to vote
        securities held by it except that the Portfolio may purchase securities
        of other investment companies to the extent permitted by (i) the 1940

     2. The Portfolio may not purchase securities on margin but the Portfolio
        may obtain such short-term credits as may be necessary for the clearance
        of purchases and sales of securities. The deposit or

                                      B-34
<PAGE>   185

        payment by the Portfolio of initial or maintenance margin in connection
        with forward contracts, futures, foreign currency futures or related
        options is not considered the purchase of a security on margin;

     3. The Portfolio may not invest in the securities of other open-end
        investment companies, or invest in the securities of closed-end
        investment companies except through purchase in the open market in a
        transaction involving no commission or profit to a sponsor or dealer
        (other than the customary broker's commission) or as part of a merger,
        consolidation or other acquisition except that the Portfolio may
        purchase securities of other investment companies to the extent
        permitted by (i) the 1940 Act, as amended from time to time, (ii) the
        rules and regulations promulgated by the SEC under the 1940 Act, as
        amended from time to time, or (iii) an exemption or other relief from
        the provisions of the 1940 Act;

     4. The Portfolio may not invest more than 5% of its net assets in warrants
        or rights valued at the lower of cost or market, nor more than 2% of its
        net assets in warrants or rights (valued on such basis) which are not
        listed on the New York or American Stock Exchanges. Warrants or rights
        acquired in units or attached to other securities are not subject to the
        foregoing limitation;

     5. The Portfolio may not invest in securities of any company if any officer
        or trustee of the Portfolio or of the Adviser owns more than 1/2 of 1%
        of the outstanding securities of such company, and such officers and
        trustees who own more than 1/2 of 1% own in the aggregate more than 5%
        of the outstanding securities of such issuer;

     6. The Portfolio may not invest in interests in oil, gas, or other mineral
        exploration or development programs or invest in oil, gas, or mineral
        leases, except that the Portfolio may acquire securities of public
        companies which themselves are engaged in such activities;

     7. The Portfolio may not invest more than 5% of its total assets in
        securities of unseasoned issuers which have been in operation directly
        or through predecessors for less than three years, except that the

        extent permitted by (i) the 1940 Act, as amended from time to time, (ii)
        the rules and regulations promulgated by the SEC under the 1940 Act, as
        amended from time to time, or (iii) an exemption or other relief from
        the provisions of the 1940 Act; or

     8. The Portfolio may not purchase or otherwise acquire any security if, as
        a result, more than 15% of its net assets (taken at current value) would
        be invested in securities that are illiquid by virtue of the absence of
        a readily available market. This policy does not apply to restricted
        securities eligible for resale pursuant to Rule 144A under the
        Securities Act of 1933 which the Trustees or the Adviser under approved

        on resale, a liquid market exists.

     2. Purchase any securities (other than obligations issued or guaranteed by
        the United States Government or by its instrumentalities), if, as a
        result, more than 5% of the Portfolio's total assets (taken at current

        a result, such Portfolio would hold more than 10% of the outstanding
        voting securities of an issuer, except that up to 25% of the Portfolio's
        total assets may be invested without regard to such limitations. Neither

     3. Invest more than 25% of its assets in a single industry, provided,
        however, that this limitation excludes shares of other open-end
        investment companies owned by the Portfolio but includes the Portfolio's
        pro rata portion of the securities and other assets owned by any such
        company. (Neither the U.S. Government nor any of its agencies or
        instrumentalities will be considered an industry for purposes of this
        restriction.)

     4. Buy or sell real estate including real estate limited partnerships,
        provided that the foregoing prohibition does not apply to a purchase and
        sale of (i) securities which are secured by real estate, (ii) securities

        operating in the real estate industry, including real estate investment

        of the ownership of its securities;

        repurchase agreements with banks in the aggregate in excess of 33 1/3%
        of the Portfolio's total assets (after giving effect to any such
        borrowing); which amount does not include borrowings and reverse
        repurchase agreements with any entity where such borrowings and reverse
        repurchase agreements are in an amount not exceeding 5% of its total
        assets and for temporary purposes only. The Portfolio will not mortgage,
        pledge or hypothecate any assets other than in connection with issuances

        forward contracts, forward commitments and other investment strategies
        and instruments;

     7. Make loans of money or property to any person, except (i) to the extent
        the securities in which the Portfolio may invest are considered to be
        loans, (ii) through the loan of portfolio securities, and (iii) to the
        extent that the Portfolio may lend money or property in connection with
        maintenance of the value of, or the Portfolio's interest with respect
        to, the securities owned by the Portfolio.

     In addition to the foregoing fundamental policies which may not be changed
without shareholder approval, the Strategic Stock Portfolio is subject to the
following policies which may be amended by the Strategic Stock Portfolio's
Trustees and which apply at the time of purchase of portfolio securities.

     1. The Portfolio may not make short sales of securities, unless at the time
        of the sale it owns or has the right to acquire an equal amount of such
        securities; provided that this prohibition does not apply to the writing
        of options or the sale of forward contracts, futures, foreign currency
        futures or related options.

     2. The Portfolio may not make investments for the purpose of exercising
        control or management although the Portfolio retains the right to vote
        securities held by it except that the Portfolio may purchase securities
        of other investment companies to the extent permitted by (i) the 1940
        Act, as amended from time to time, (ii) the rules and regulations
        promulgated by the SEC under the 1940 Act, as amended from time to time,
        or (iii) an exemption or other relief from the provisions of the 1940
        Act;

     3. The Portfolio may not purchase securities on margin but the Portfolio
        may obtain such short-term credits as may be necessary for the clearance
        of purchases and sales of securities. The deposit or payment by the
        Portfolio of initial or maintenance margin in connection with forward
        contracts, futures, foreign currency futures or related options is not
        considered the purchase of a security on margin;

                                      B-36
<PAGE>   187

     4. The Portfolio may not invest in the securities of other open-end
        investment companies, or invest in the securities of closed-end
        investment companies except as part of a merger, consolidation or other
        acquisition and except that the Portfolio may purchase securities of
        other investment companies to the extent permitted by (i) the 1940 Act,
        as amended from time to time, (ii) the rules and regulations promulgated
        by the SEC under the 1940 Act, as amended from time to time, or (iii) an
        exemption or other relief from the provisions of the 1940 Act;

     5. The Portfolio may not invest more than 5% of its net assets in warrants
        or rights valued at the lower of cost or market, nor more than 2% of its
        net assets in warrants or rights (valued on such basis) which are not
        listed on the New York or American Stock Exchanges. Warrants or rights
        acquired in units or attached to other securities are not subject to the
        foregoing limitation;

     6. The Portfolio may not invest in securities of any company if any officer
        or trustee of the Portfolio or of the Adviser owns more than 1/2 of 1%
        of the outstanding securities of such company, and such officers and
        trustees who own more than 1/2 of 1% own in the aggregate more than 5%
        of the outstanding securities of such issuer;

     7. The Portfolio may not invest in interests in oil, gas, or other mineral
        exploration or development programs or invest in oil, gas, or mineral
        leases, except that the Portfolio may acquire securities of public
        companies which themselves are engaged in such activities;

     8. The Portfolio may not invest more than 5% of its total assets in
        securities of unseasoned issuers which have been in operation directly
        or through predecessors for less than three years, except that the
        Portfolio may purchase securities of other investment companies to the
        extent permitted by (i) the 1940 Act, as amended from time to time, (ii)
        the rules and regulations promulgated by the SEC under the 1940 Act, as
        amended from time to time, or (iii) an exemption or other relief from
        the provisions of the 1940 Act; or

     9. The Portfolio may not purchase or otherwise acquire any security if, as
        a result, more than 15% of its net assets (taken at current value) would
        be invested in securities that are illiquid by virtue of the absence of
        a readily available market. This policy does not apply to restricted
        securities eligible for resale pursuant to Rule 144A under the
        Securities Act of 1933 which the Trustees or the Adviser under approved
        guidelines, may determine are liquid nor does it apply to other
        securities for which, notwithstanding legal or contractual restrictions
        on resale, a liquid market exists.

     Each trustee/director holds the same position with each of the funds in the
Fund Complex. As of the date of this Statement of Additional Information, there
are 64 operating funds in the Fund Complex. Each trustee/director who is not an
affiliated person of Van Kampen Investments, the Advisers or the Distributor
(each a "Non-Affiliated Trustee") is compensated by an annual retainer and
meeting fees for services to the funds in the Fund Complex. Each fund in the
Fund Complex (except the money market series of the Van Kampen Series Fund Inc.)
provides a deferred compensation plan to its Non-Affiliated Trustees that allows
trustees/directors to defer receipt of their compensation and earn a return on
such deferred amounts. Deferring compensation has the economic effect as if the
Non-Affiliated Trustee reinvested his or her compensation into the funds. Each
fund in the Fund Complex (except the money market series of the Van Kampen
Series Fund Inc.) provides a retirement plan to its Non-Affiliated Trustees that
provides Non-Affiliated Trustees with compensation after retirement, provided
that certain eligibility requirements are met as more fully described below.


     The compensation of each Non-Affiliated Trustee includes an annual retainer
in an amount equal to $50,000 per calendar year, due in four quarterly
installments on the first business day of each quarter. Payment of the annual
retainer is allocated among the funds in the Fund Complex (except the money
market series of the Van Kampen Series Fund Inc.) on the basis of the relative
net assets of each fund as of the last business day of the preceding calendar
quarter. The compensation of each Non-Affiliated Trustee includes a per meeting
fee from each fund in the Fund Complex (except the money market series of the
Van Kampen Series Fund Inc.) in the amount of $200 per quarterly or special
meeting attended by the Non-Affiliated Trustee, due on the date of the meeting,
plus reasonable expenses incurred by the Non-Affiliated Trustee in connection
with his or her services as a trustee, provided that no compensation will be
paid in connection with certain telephonic special meetings.

     Under the deferred compensation plan, each Non-Affiliated Trustee generally
can elect to defer receipt of all or a portion of the compensation earned by
such Non-Affiliated Trustee until retirement. Amounts deferred are retained by
the Fund and earn a rate of return determined by reference to the return on the
common shares of such Fund or other funds in the Fund Complex as selected by the
respective Non-Affiliated Trustee, with the same economic effect as if such
Non-Affiliated Trustee had invested in one or more funds in the Fund Complex. To
the extent permitted by the 1940 Act, the Fund may invest in securities of those
funds selected by the Non-Affiliated Trustees in order to match the deferred
compensation obligation. The deferred compensation plan is not funded and
obligations thereunder represent general unsecured claims against the general
assets of the Fund.

     Under the retirement plan, a Non-Affiliated Trustee who is receiving
compensation from such Fund prior to such Non-Affiliated Trustee's retirement,
has at least 10 years of service (including years of service prior to adoption
of the retirement plan) and retires at or after attaining the age of 60, is
eligible to receive a retirement benefit equal to $2,500 per year for each of

</TABLE>


- ------------------------------------

(1) Mr. Yovovich joined the Board of Trustees on October 22, 1998 and therefore
    does not have a complete fiscal year of information to report in this table.
    Trustees not eligible for compensation are not included in the Compensation
    Table.


(2) The amounts shown in this column represent the Aggregate Compensation before
    Deferral from all series of the Trust with respect to the Trust's fiscal
    year ended December 31, 1999. The details of aggregate compensation before
    deferral for each series are shown in Table A below. Certain trustees
    deferred compensation from the Trust during the fiscal year ended December
    31, 1999; the aggregate compensation deferred from all ten series of the
    Trust is as follows: Mr. Branagan,        ; Ms. Heagy,        ; Mr. Kennedy,
           ; Mr. Nelson,        ; Mr. Rooney,        ; Mr. Sisto,        ; and
    Mr. Whalen,        . The details of amounts deferred for each series are
    shown in Table B below. Amounts deferred are retained by the respective
    Portfolio and earn a rate of return determined by reference to either the
    return on the common shares of the Portfolio or other funds in the Fund
    Complex as selected by the respective Non-Affiliated Trustee, with the same
    economic effect as if such Non-Affiliated Trustee had invested in one or
    more funds in the Fund Complex. To the extent permitted by the 1940 Act,
    each Fund may invest in securities of those funds selected by the
    Non-Affiliated Trustees in order to match the deferred compensation
    obligation. The cumulative deferred compensation (including interest)
    accrued with respect to each trustee from all ten portfolios of the Trust as
    of the Trust's fiscal year ended December 31, 1999 is as follows: Mr.
    Branagan,        ; Dr. Caruso,        ; Mr. Gaughan,        ; Ms. Heagy,
           ; Mr. Kennedy,        ; Mr. Lipshie,      ; Mr. Miller,        ; Mr.
    Nelson,        ; Mr. Rees,        ; Mr. Robinson,        ; Mr. Rooney,
           ; Mr. Sisto,        ; Mr. Vernon,        ; and Mr. Whalen,        .
    The details of cumulative deferred compensation (including interest) for
    each Portfolio are shown in Table C. The deferred compensation plan is
    described above the Compensation Table.



(3) The amounts shown in this column represent the sum of the retirement
    benefits accrued by the operating investment companies in the Fund Complex
    for each of the trustees for the Funds' respective fiscal years ended in
    1999. The retirement plan is described above the Compensation Table.


                                      B-45
<PAGE>   196

(4) For each trustee, this is the sum of the estimated maximum annual benefits
    payable by the operating investment companies in the Fund Complex for each
    year of the 10-year period commencing in the year of such trustee's
    anticipated retirement. The Retirement Plan is described above the
    Compensation Table.


(5) The amounts shown in this column represent the aggregate compensation paid
    by all operating investment companies in the Fund Complex as of December 31,
    1999 before deferral by the trustees under the deferred compensation plan.
    Because the funds in the Fund Complex have different fiscal year ends, the
    amounts shown in this column are presented on a calendar year basis. Certain
    trustees deferred all or a portion of their aggregate compensation from the
    Fund Complex during the calendar year ended December 31, 1999. The deferred
    compensation earns a rate of return determined by reference to the return on
    the shares of the funds in the Fund Complex as selected by the respective
    Non-Affiliated Trustee, with the same economic effect as if such
    Non-Affiliated Trustee had invested in one or more funds in the Fund
    Complex. To the extent permitted by the 1940 Act, the Fund may invest in
    securities of those investment companies selected by the Non-Affiliated
    Trustees in order to match the deferred compensation obligation. The
    Advisers and their affiliates also serve as investment adviser for other
    investment companies; however, with the exception of Mr. Whalen, the
    Non-Affiliated Trustees were not trustees of such investment companies.
    Combining the Fund Complex with other investment companies advised by the
    Advisers and their affiliates, Mr. Whalen received Total Compensation of
            during the calendar year ended December 31, 1999.



     As of April   , 2000, the trustees and officers of the Fund as a group
owned less than 1% of the shares of the Fund.

INVESTMENT ADVISORY AGREEMENTS

     The Trust and the Adviser are parties to an investment advisory agreement
(the "Combined Advisory Agreement") pursuant to which the Trust retains the
Adviser to manage the investment of assets and to place orders for the purchase
and sale of portfolio securities for certain portfolios including the Asset
Allocation Portfolio, the Domestic Income Portfolio, the Enterprise Portfolio,
the Government Portfolio and the Money Market Portfolio (collectively, the
"Combined Portfolios"). The Trust and the Adviser are also parties to other
investment advisory agreements pursuant to which the Adviser manages the
investment of assets and places orders for the purchase and sale of portfolio
securities for the remaining Portfolios including six advisory agreements
designated herein as "Comstock Advisory Agreement," "Emerging Growth Advisory
Agreement," "Global Equity Advisory Agreement," "Growth and Income Advisory
Agreement", "Morgan Stanley Real Estate Securities Advisory Agreement" and the
"Strategic Stock Advisory Agreement" for the Comstock Portfolio, the Emerging
Growth Portfolio, the Global Equity Portfolio, the Growth and Income

                                      B-47
<PAGE>   198

Portfolio, the Morgan Stanley Real Estate Securities Portfolio and the Strategic
Stock Portfolio, respectively (such advisory agreements together with the
Combined Advisory Agreement are referred to herein collectively as the "Advisory
Agreements"). Under the Advisory Agreements, the Adviser is responsible for
obtaining and evaluating economic, statistical, and financial data and for
formulating and implementing investment programs in furtherance of each
Portfolio's investment objectives. The Adviser also furnishes at no cost to the
Portfolios (except as noted herein) the services of sufficient executive and
clerical personnel for the Trust as are necessary to prepare registration
statements, prospectuses, shareholder reports, and notices and proxy
solicitation materials. In addition, the Adviser furnishes at no cost to the
Portfolio the services of a President of the Trust, one or more Vice Presidents
as needed, and a Secretary.

     Under the Advisory Agreements, the Trust bears the cost of its accounting
services, which includes maintaining its financial books and records and
calculating the daily net asset value of each Portfolio. The costs of such
accounting services include the salaries and overhead expenses of a Treasurer or
other principal financial officer and the personnel operating under his
direction. The services are provided at cost which is allocated among the
investment companies advised by the Adviser. A portion of these amounts are paid
to the Adviser or its parent as reimbursement of personnel, office space,
facilities and equipment costs attributable to the provision of accounting
services to the Trust. The Trust also pays custodian fees, legal and independent
accountant fees, trustee fees (other than those who are affiliated persons of
the Adviser, Distributor or Van Kampen Investments) the costs of reports and
proxies to shareholders and all other ordinary expenses not specifically assumed
by the Adviser. The Advisory Agreements also provide that the Adviser shall not
be liable to the company for any actions or omissions if it acted without
willful misfeasance, bad faith, negligence or reckless disregard of its
obligations.

     Under the Advisory Agreements, the Trust pays to the Adviser as
compensation for the services rendered, facilities furnished, and expenses paid
by it, an annual fee payable monthly computed on average daily net assets as
follows:

</TABLE>

For the Global Equity Portfolio and Morgan Stanley Real Estate Securities
Portfolio, the Adviser has entered into subadvisory agreements (the "Subadvisory
Agreement") to assist the Adviser in performing its

                                      B-48
<PAGE>   199

investment advisory functions. Under the Subadvisory Agreements, the Subadviser
receives on an annual basis 50% of the net advisory fees received by the Adviser
with respect to such Portfolios.

     The Adviser has voluntarily agreed to reimburse the Portfolios for all
expenses as a percent of average daily net assets in excess of the following:


<TABLE>
<S>                                                           <C>
- --------------------------------------------------------------------

Asset Allocation Portfolio, Domestic Income Portfolio,
Enterprise Portfolio, Government Portfolio and Money Market
Portfolio (based upon their combined average daily net
assets).....................................................
Comstock Portfolio..........................................
Emerging Growth Portfolio...................................
Global Equity Portfolio.....................................
Growth and Income Portfolio.................................
Morgan Stanley Real Estate Securities Portfolio.............
Strategic Stock Portfolio...................................
</TABLE>



     The Combined Advisory Agreement also provides that, in the event the
ordinary business expenses of any of the Combined Portfolios for any fiscal year
exceed 0.95% of the average daily net assets, the compensation due the Adviser
will be reduced by the amount of such excess and that, if a reduction in and
refund of the advisory fee is insufficient, the Adviser will pay the Combined
Portfolios monthly an amount sufficient to make up the deficiency, subject to
readjustment during the year. Ordinary business expenses do not include (1)
interest and taxes, (2) brokerage commissions, (3) any distribution expenses
which may be incurred in the event the Combined Portfolios' Distribution Plan is
implemented, and (4) certain litigation and indemnification expenses as
described in the Combined Advisory Agreement.


     The average daily net assets of a Portfolio is determined by taking the
average of all of the determinations of net assets of that Portfolio for each
business day during a given calendar month. The fee is payable for each calendar
month as soon as practicable after the end of that month. The fee payable to the
Adviser is reduced by any commissions, tender solicitation and other fees,
brokerage or similar payments received by the Adviser or any other direct or
indirect majority owned subsidiary of Van Kampen Investments, in connection with
the purchase and sale of portfolio investments of the Portfolios, less any
direct expenses incurred by such subsidiary of Van Kampen Investments in
connection with obtaining such payments. The Adviser agrees to use its best
efforts to recapture tender solicitation fees and exchange offer fees for the
Portfolios benefit, and to advise the Trustees of the Portfolios of any other
commissions, fees, brokerage or similar payments which may be possible under
applicable laws for the Adviser or any other direct or indirect majority owned
subsidiary of Van Kampen Investments, to receive in connection with the
Portfolios investment transactions or other arrangements which may benefit the
Portfolios.

     The Advisory Agreements with respect to each subject Portfolio may be
continued from year to year if specifically approved at least annually (a)(i) by
the Trustees or (ii) by a vote of a majority of such Portfolio's outstanding
voting securities and (b) by the affirmative vote of a majority of the Trustees
who are not parties to the agreement or interested persons of any such party by
votes cast in person at a meeting called for such purpose. The Advisory
Agreements provide that an agreement shall terminate automatically if assigned
and that it may be terminated without penalty by either party on 60 days'
written notice.


DISTRIBUTOR

     The Distributor acts as the principal underwriter of the shares of the
Trust pursuant to a written agreement (the "Distribution and Service
Agreement"). The Distributor's obligation is an agency or "best efforts"
arrangement under which the Distributor is not obligated to sell any stated
number of shares. The Distribution and Service Agreement is renewable from year
to year if approved (a) by the Trust's Trustees or by a vote of a majority of
the Trust's outstanding voting securities and (b) by the affirmative vote of a
majority of Trustees who are not parties to the Distribution and Service
Agreement or interested persons of any party, by votes cast in person at a
meeting called for that purpose. The Distribution and Service Agreement provides
that it will terminate if assigned, and that it may be terminated without
penalty by either party on 90 days' written notice.

     The Distributor bears the cost of printing (but not typesetting)
prospectuses used in connection with this offering and certain other costs
including the cost of supplemental sales literature and advertising. The Trust
pays all expenses attributable to the registrations of its shares under federal
law, including registration and

                                      B-50
<PAGE>   201

filing fees, the cost of preparation of the prospectuses, related legal and
auditing expenses, and the cost of printing prospectuses for current
shareholders.


     Each Portfolio has adopted a distribution plan (the "Distribution Plan")
with respect to its Class II Shares pursuant to Rule 12b-1 under the 1940 Act.
Each Portfolio also has adopted a service plan (the "Service Plan") with respect
to its Class II Shares. The Distribution Plan and the Service Plan sometimes are
referred to herein as the "Plans". The Plans provide that a Portfolio may spend
a portion of the average daily net assets attributable to its Class II Shares in
connection with distribution of such class of shares and in connection with the
provision of ongoing services to shareholders of such class. The Distribution
Plan and the Service Plan are being implemented through the Distribution and
Service Agreement with the Distributor and sub-agreements with parties that may
provide for their customers or clients certain services or assistance, which may
include, but not be limited to, processing purchase and redemption transactions,
establishing and maintaining shareholder accounts regarding a Portfolio, and
such other services as may be agreed to from time to time and as may be
permitted by applicable statute, rule or regulation.



     The Distributor must submit quarterly reports to the Board of Trustees of
the Trust setting forth separately by Portfolio all amounts paid under the
Distribution Plan and the purposes for which such expenditures were made,
together with such other information as from time to time is reasonably
requested by the Trustees. The Plans provide that they will continue in full
force and effect from year to year so long as such continuance is specifically
approved by a vote of the Trustees, and also by a vote of the disinterested
Trustees, cast in person at a meeting called for the purpose of voting on the
Plans. Each of the Plans may not be amended to increase materially the amount to
be spent for the services described therein with respect to Class II Shares
without approval by a vote of a majority of the outstanding voting shares of
Class II Shares, and all material amendments to either of the Plans must be
approved by the Trustees and also by the disinterested Trustees. Each of the
Plans may be terminated with respect to Class II Shares at any time by a vote of
a majority of the disinterested Trustees or by a vote of a majority of the
outstanding voting shares of Class II Shares.



     The Plans generally provide for a Portfolio to reimburse the lesser of (i)
the distribution and service fees at the rates specified in the prospectus or
(ii) the amount of the Distributor's actual expenses incurred less any deferred
sales charges it received. To the extent the Distributor is not fully reimbursed
in a given year, there is no carryover of such unreimbursed amounts to
succeeding years.


TRANSFER AGENT


     The Fund's transfer agent, shareholder service agent and dividend
disbursing agent is Van Kampen Investor Services Inc., PO Box 218256, Kansas
City, MO 64121-8256. The transfer agency prices are determined through
negotiations with the Board of Trustees of the Trust and are based on
competitive market benchmarks.


PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION

     The Adviser is responsible for decisions to buy and sell securities for the
Portfolios, the selection of brokers and dealers to effect the transactions and
the negotiation of prices and any brokerage commissions on such transactions.
While the Adviser will be primarily responsible for the placement of the
Portfolios' investments, the policies and practices in this regard will at all
times be subject to review by the Trustees.

     Transactions in debt securities generally made by the Fund are principal
transactions at net prices with little or no brokerage costs. Such securities
are normally purchased directly from the issuer or in the over-the-counter
market from an underwriter or market maker for the securities. Purchases from
underwriters of portfolio securities include a commission or concession paid by
the issuer to the underwriter and purchases from dealers serving as market
makers include a spread or markup to the dealer between the bid and asked price.
Sales to dealers are effected at bid prices. The Portfolios may also purchase
certain money market instruments directly

                                      B-51
<PAGE>   202

from an issuer, in which case no commissions or discounts are paid, or may
purchase and sell listed bonds on a exchange, which are effected through brokers
who charge a commission for their services.

     The Adviser is responsible for placing portfolio transactions and does so
in a manner deemed fair and reasonable to the Portfolios and not according to
any formula. The primary consideration in all portfolio transactions is prompt
execution of orders in an effective manner at the most favorable price. In
selecting broker/dealers and in negotiating prices and any brokerage commissions
on such transactions, the Adviser considers the firm's reliability, integrity
and financial condition and the firm's execution capability, the size and
breadth of the market for the security, the size of and difficulty in executing
the order, and the best net price. There are many instances when, in the
judgment of the Adviser, more than one firm can offer comparable execution
services. In selecting among such firms, consideration may be given to those
firms which supply research and other services in addition to execution
services. The Adviser is authorized to pay higher commissions to brokerage firms
that provide it with investment and research information than to firms which do
not provide such services if the Adviser determines that such commissions are
reasonable in relation to the overall services provided. No specific value can
be assigned to such research services which are furnished without cost to the
Adviser. Since statistical and other research information is only supplementary
to the research efforts of the Adviser to the Portfolios and still must be
analyzed and reviewed by its staff, the receipt of research information is not
expected to reduce its expenses materially. The investment advisory fee is not
reduced as a result of the Adviser's receipt of such research services. Services
provided may include (a) furnishing advice as to the value of securities, the
advisability of investing in, purchasing or selling securities, and the
availability of securities or pur-chasers or sellers of securities; (b)
furnishing analyses and reports concerning issuers, industries, securities,
economic factors and trends, portfolio strategy, and the performance of
accounts; and (c) effecting securities transactions and performing functions
incidental thereto (such as clearance, settlement and custody). Research
services furnished by firms through which the Fund effects its securities
transactions may be used by the Adviser in servicing all of its advisory
accounts; not all of such services may be used by the Adviser in connection with
the Fund.

     The Adviser also may place portfolio transactions, to the extent permitted
by law, with brokerage firms affiliated with the Portfolios, the Adviser or the
Distributor and with brokerage firms participating in the distribution of the
Portfolios' shares if it reasonably believes that the quality of execution and
the commission are comparable to that available from other qualified firms.
Similarly, to the extent permitted by law and subject to the same considerations
on quality of execution and comparable commission rates, the Adviser may direct
an executing broker to pay a portion or all of any commissions, concessions or
discounts to a firm supplying research or other services or to a firm
participating in the distribution of the Portfolios' shares.

     The Adviser may place Portfolio transactions at or about the same time for
other advisory accounts, including other investment companies. The Adviser seeks
to allocate portfolio transactions equitably whenever concurrent decisions are
made to purchase or sell securities for the Portfolios and another advisory
account. In some cases, this procedure could have an adverse effect on the price
or the amount of securities available to the Portfolios. In making such
allocations among the Portfolios and other advisory accounts, the main factors
considered by the Adviser are the respective sizes of the Portfolios and other
advisory accounts, the respective investment objectives, the relative size of
portfolio holdings of the same or comparable securities, the availability of
cash for investment, the size of investment commitments generally held and
opinions of the persons responsible for recommending the investment.

     Effective October 31, 1996, Morgan Stanley & Co. Incorporated ("Morgan
Stanley") became an affiliate of the Adviser. Effective May 31, 1997, Dean
Witter Reynolds, Inc. ("Dean Witter") became an affiliate of the Adviser. The
trustees have adopted certain policies incorporating the standards of Rule 17e-1
issued by the SEC under the 1940 Act which requires that the commissions paid to
affiliates of the Portfolios must be reasonable and fair compared to the
commissions, fees or other remuneration received or to be received by other
brokers in connection with comparable transactions involving similar securities
during a comparable period of time. The rule and procedures also contain review
requirements and require the Adviser to furnish reports to the trustees and to
maintain records in connection with such reviews. After consideration of all
factors deemed relevant, the trustees will consider from time to time whether
the advisory fee for the Fund will be reduced by all or a portion of the
brokerage commission given to affiliated brokers.

DETERMINATION OF NET ASSET VALUE


     The net asset value of the shares of each Portfolio is computed by dividing
the value of all securities held by the Portfolio plus other assets, less
liabilities, by the number of shares outstanding. This computation is determined
for each Portfolio as of the close of business of the New York Stock Exchange
(the "Exchange") (currently 4:00 p.m., New York time) on each business day on
which the Exchange is open.

MONEY MARKET PORTFOLIO NET ASSET VALUATION

     The Portfolio's use of the amortized cost method of valuing its portfolio
securities is permitted by a rule adopted by the SEC. Under this rule, the
Portfolio must maintain a dollar-weighted average portfolio maturity of 90 days
or less, purchase only instruments having remaining maturities of thirteen
months or less and invest only in securities determined by the Adviser to be of
eligible quality with minimal credit risks. The valuation of each Portfolio's
investments is based upon their amortized cost, which does not take into account
unrealized capital gains or losses. Amortized cost valuation involves initially
valuing an instrument at its cost and thereafter, assuming a constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument. While this
method provides certainty in valuation, it may result in periods during which
value, as determined by amortized cost, is higher or lower than the price that
the Portfolio would receive if it sold the instrument.

     The Portfolio has established procedures reasonably designed, taking into
account current market conditions and the Portfolio's investment objective, to
stabilize the net asset value per share for purposes of sales and redemptions at
$1.00. These procedures include review by the Trustees, at such intervals as the
Portfolio or the Trustees deem appropriate, to determine the extent, if any, to
which the new asset value per share calculated by using available market
quotations deviates from $1.00 per share based on amortized cost. In the event
such deviation should exceed four tenths of one percent, the Trustees are
required to promptly consider what action, if any, should be initiated. If the
Trustees believe that the extent of any deviation from a $1.00 amortized cost
price per share may result in material dilution or other unfair results to new
or existing shareholders, it will take such steps as it considers appropriate to
eliminate or reduce these consequences to the extent reasonably practicable.
Such steps may include selling portfolio securities prior to maturity;

                                      B-54
<PAGE>   205

shortening the average maturity of the portfolio; withholding or reducing
dividends; or utilizing a net asset value per share determined by using
available market quotations.

STOCK PORTFOLIOS NET ASSET VALUATION

     The net asset value of these Portfolios is computed by (i) valuing
securities listed or traded on a national securities exchange at the last sale
price, or if there has been no sale that day at the mean between the last
reported bid and asked prices (ii) valuing unlisted securities for which
over-the-counter market quotations are readily available at the most recent bid
price as supplied by National Association of Securities Dealers Automated
Quotations ("NASDAQ") or by broker-dealers, and (iii) valuing any securities for
which market quotations are not readily available, and any other assets at fair
value as determined in good faith by the Adviser based on procedures approved by
the Trustees. Options, futures contracts and options thereon, which are traded
on exchanges, are valued at their last sale or settlement price as of the close
of such exchanges or if no sales are reported, at the mean between the last
reported bid and asked prices. Securities with a remaining maturity of 60 days
or less are valued on an amortized cost basis, which approximates market value.
Securities for which market quotations are not readily available, and any other
assets are valued at fair value as determined in good faith by the Adviser based
on procedures approved by the Trustees.

GOVERNMENT PORTFOLIO NET ASSET VALUATION

     U.S. Government securities are traded in the over-the-counter market and
are valued at the mean between the last reported bid and asked prices. Such
valuations are based on quotations of one or more dealers that make markets in
the securities as obtained from such dealers or from a pricing service. Options,
interest rate futures contracts and options thereon, which are traded on
exchanges, are valued at their last sale or settlement price as of the close of
such exchanges or if no sales are reported, at the mean between the last
reported bid and asked prices. Securities with a remaining maturity of 60 days
or less are valued on an amortized cost basis, which approximates market value.
Securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by the Adviser based on
procedures approved by the Trust's Trustees.

FAIR VALUE PRICING

     With respect to certain Portfolios, trading in securities on European and
Far Eastern securities exchanges and over-the-counter markets is normally
completed well before the close of business on each business day in New York
(i.e., a day on which the Exchange is open). In addition, European or Far
Eastern securities trading generally or in a particular country or countries may
not take place on all business days for the Exchange. Furthermore, trading takes
place on all business days in Japanese markets, on certain Saturdays, and in
various foreign markets on days which are not business days for the Exchange,
and on which such Portfolios net asset value is not calculated, and on which
such Portfolios does not effect sales, redemptions and repurchases of its
shares. There may be significant variations in the net asset value of Portfolio
shares on days when net asset value is not calculated and on which shareholders
cannot redeem on account of changes in prices of stocks traded in foreign stock
markets.

PURCHASE AND REDEMPTION OF SHARES

     The purchase of shares of the Portfolios is currently limited to the
Accounts as explained in the Prospectus. Such shares are sold and redeemed at
their respective net asset values as described in the Prospectus.

     Redemptions are not made on days during which the Exchange is closed. The
right of redemption may be suspended and the payment therefor may be postponed
for more than seven days during any period when (a) the Exchange is closed for
other than customary weekends or holidays; (b) trading on the Exchange is

                                      B-55

restricted; (c) an emergency exists as a result of which disposal by the
Portfolio of securities owned by it is not reasonably practicable or it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets; or (d) the SEC, by order, so permits.

TAX STATUS

     The Trust and each of its Portfolios will be treated as separate
corporations for federal income tax purposes. A Portfolio will be subject to tax
if, among other things, it fails to distribute net capital gains, or if its
annual distributions, as a percentage of its income, are less than the
distributions required by tax laws.

     From time to time, the Portfolios, except the Money Market Portfolio, may
advertise their total return for prior periods. Any such advertisement would
include at least average annual total return quotations for one, five and ten
year periods or for the life of the Portfolio. Other total return quotations,
aggregate or average, over other time periods may also be included. Total return
calculations do not take into account expenses at the "wrap" or contractholder
level as explained in the prospectus. Investors should also review total return
calculations that include those expenses.


     The total return of a Portfolio for a particular period represents the
increase (or decrease) in the value of a hypothetical investment in the
Portfolio from the beginning to the end of the period. Total return is
calculated by subtracting the value of the initial investment from the ending
value and showing the difference as a percentage of the initial investment; the
calculation assumes the initial investment is made at the maximum public
offering price and that all income dividends or capital gains distributions
during the period are reinvested in Portfolio shares at net asset value. Total
return is based on historical earnings and asset value fluctuations and is not
intended to indicate future performance. A Portfolio's total return will vary
depending on market conditions, the securities comprising the Portfolio's
investment holdings, the Portfolio's operating expenses and unrealized net
capital gains or losses during the period. No adjustments are made to reflect
any income taxes payable by shareholders on dividends and distributions paid by
the Portfolio.

     Average annual total return quotations for periods of two or more years are
computed by finding the average annual compounded rate of return over the period
that would equate the initial amount invested to the ending redeemable value.

                                      B-57
<PAGE>   208

     A Portfolio may, in supplemental sales literature, advertise
non-standardized total return figures representing the cumulative,
non-annualized total return of the Portfolio from a given date to a subsequent
given date. Cumulative non-standardized total return is calculated by measuring
the value of an initial investment in a Portfolio at a given time, determining
the value of all subsequent reinvested distributions, and dividing the net
change in the value of the investment as of the end of the period by the amount
of the initial investment and expressing the result as a percentage.
Non-standardized total return will be calculated separately for each Portfolio.

     In addition to total return information, certain Portfolios may also
advertise their current "yield." Yield figures are based on historical earnings
and are not intended to indicate future performance. Yield is determined by
analyzing the Portfolio's net income per share for a 30-day (or one-month)
period (which period will be stated in the advertisement), and dividing by the
maximum offering price per share on the last day of the period. A "bond
equivalent" annualization method is used to reflect a semiannual compounding.
Yield calculations do not take into account expenses at the "wrap" or
contractholder level as expanded in the prospectus. Investors should also review
yield calculations that include those expenses.

     For purposes of calculating yield quotations, net income is determined by a
standard formula prescribed by the SEC to facilitate comparison with yields
quoted by other investment companies. Net income computed for this formula
differs from net income reported by a Portfolio in accordance with generally
accepted accounting principles and from net income computed for federal income
tax reporting purposes. Thus the yield computed for a period may be greater or
lesser than a Portfolio's then current dividend rate.

     A Portfolio's yield is not fixed and will fluctuate in response to
prevailing interest rates and the market value of portfolio securities, and as a
function of the type of securities owned by a Portfolio, portfolio maturity and
a Portfolio's expenses.

     Yield quotations should be considered relative to changes in the net asset
value of a Portfolio's shares, a Portfolio's investment policies, and the risks
of investing in shares of a Portfolio. The investment return and principal value
of an investment in a Portfolio will fluctuate so that an investor's shares,
when redeemed, may be worth more or less than their original cost.

     The Adviser may, from time to time, waive advisory fees or reimburse a
certain amount of the future ordinary business expenses of a Portfolio. Such
waiver/reimbursement will increase the yield or total return of such Portfolio.
The Adviser may stop waiving fees or reimbursing expenses at any time without
prior notice.

     From time to time the Money Market Portfolio advertises its "yield" and
"effective yield." Both yield figures are based on historical earnings and are
not intended to indicate future performance. The "yield" of the Portfolio refers
to the income generated by an investment in the Money Market Portfolio over a
seven-day period (which period will be stated in the advertisement). This income
is then "annualized." That is, the amount of income generated by the investment
during that week is assumed to be generated each week over a 52-week period and
is shown as a percentage of the investment. The "effective yield" is calculated
similarly but, when annualized, the income earned by an investment in the Money
Market Portfolio is assumed to be reinvested. The "effective yield" will be
slightly higher than the "yield" because of the compounding effect of this
assumed reinvestment.

     Since yield fluctuates, yield data cannot necessarily be used to compare an
investment in a Portfolio's shares with bank deposits, savings accounts and
similar investment alternatives which often provide an agreed or guaranteed
fixed yield for a stated period of time. Shareholders should remember that yield
is generally a function of the kind and quality of the instrument held in a
portfolio, portfolio maturity, operating expenses and market conditions.

     From time to time, certain Portfolios may include in sales literature and
shareholder reports a quotation of the current "distribution rate" for shares of
such Portfolios. Distribution rate is a measure of the level of income and
short-term capital gain dividends, if any, distributed for a specified period.
Distribution rate differs from yield, which is a measure of the income actually
earned by a Portfolio's investments, and from total

                                      B-58
<PAGE>   209

return, which is a measure of the income actually earned by, plus the effect of
any realized and unrealized appreciation or depreciation of, such investments
during a stated period. Distribution rate is, therefore, not intended to be a
complete measure of a Portfolio's performance. Distribution rate may sometimes
be greater than yield since, for instance, it may not include the effect of
amortization of bond premiums, and may include non-recurring short-term capital
gains and premiums from futures transactions engaged in by the Portfolios.

     From time to time marketing materials may provide a portfolio manager
update, an adviser update or discuss general economic conditions and outlooks. A
Portfolio's marketing materials may also show the Portfolio's asset class
diversification, top five sectors, ten largest holdings and other Portfolio
asset structures, such as duration, maturity, coupon, NAV, rating breakdown, AMT
exposure and number of issues in the portfolio. Materials may also mention how
the Distributor believes a Portfolio compares relative to other Portfolio's of
the Adviser. Materials may also discuss the Dalbar Financial Services study from
1984 to 1994 which studied investor cash flow into and out of all types of
mutual funds. The ten year study found that investors who bought mutual fund
shares and held such shares outperformed investors who bought and sold. The
Dalbar study conclusions were consistent regardless of if shareholders purchased
their funds in direct or sales force distribution channels. The study showed
that investors working with a professional representative have tended over time
to earn higher returns than those who invested directly. The Portfolios will
also be marketed on the internet.

     In reports or other communications to shareholders or in advertising
material, a Portfolio may compare its performance with that of other mutual
funds as listed in the ratings or rankings prepared by Lipper Analytical
Services, Inc., CDA, Morningstar Mutual Funds or similar independent services
which monitor the performance of mutual funds, with the Consumer Price Index,
the Dow Jones Industrial Average Index, Standard & Poor's indices, NASDAQ
Composite Index, other appropriate indices of investment securities, or with
investment or savings vehicles. The performance information may also include
evaluations of such Portfolio published by nationally recognized ranking
services and by nationally recognized financial publications. Such comparative
performance information will be stated in the same terms in which the
comparative data or indices are stated. Such advertisements and sales material
may also include a yield quotation as of a current period. In each case, such
total return and yield information, if any, will be calculated pursuant to rules
established by the SEC and will be computed separately for each Portfolio. For
these purposes, the performance of the Portfolios, as well as the performance of
other mutual funds or indices, do not reflect various charges, the inclusion of
which would reduce portfolio performance.

     The Portfolios may also utilize performance information in hypothetical
illustrations. For example, the Portfolios may, from time to time: (1)
illustrate the benefits of tax-deferral by comparing taxable investments to
investments made through tax-deferred retirement plans; (2) illustrate in graph
or chart form, or otherwise, the benefits of dollar cost averaging by comparing
investments made pursuant to a systematic investment plan to investments made in
a rising market; (3) illustrate allocations among different types of mutual
funds for investors of different stages of their lives; and (4) in reports or
other communications to shareholders or in advertising material, illustrate the
benefits of compounding at various assumed rates of return.

     The Trust's Annual Report and Semiannual Report prior to the date hereof,
contain additional performance information about each of the Trust's portfolios;
however, the Comstock Portfolio had not commenced investment operations and,
accordingly, no information regarding the Comstock Portfolio is contained
therein. A copy of the Annual Report or Semiannual Report may be obtained
without charge by calling or writing the Trust at the telephone number and
address printed on the back cover of the Prospectus.


MONEY MARKET PORTFOLIO YIELD INFORMATION


     The yield of the Portfolio is its net income expressed in annualized terms.
The Securities and Exchange Commission requires by rule that a yield quotation
set forth in an advertisement for a "money market" fund be computed by a
standardized method based on a historical seven calendar day period. The
standardized yield is computed by determining the net change (exclusive of
realized gains and losses and unrealized appreciation and depreciation) in the
value of a hypothetical pre-existing account having a balance of one share at
the

                                      B-59
<PAGE>   210

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 365/7. The determination of
net change in account value reflects the value of additional shares purchased
with dividends from the original share, dividends declared on both the original
share and such additional shares, and all fees that are charged to all
shareholder accounts, in proportion to the length of the base period and the
Portfolio's average account size. The Portfolio may also calculate its effective
yield by compounding the unannualized base period return (calculated as
described above) by adding 1 to the base period return, raising the sum to a
power equal to 365 divided by 7, and subtracting one.

     The yield quoted at any time represents the amount being earned on a
current basis for the indicated period and is a function of the types of
instruments in the Portfolio, their quality and length of maturity, and the
Portfolio's operating expenses. The length of maturity for the Portfolio is the
average dollar weighted maturity of the Portfolio. This means that the Portfolio
has an average maturity of a stated number of days for all of its issues. The
calculation is weighted by the relative value of the investment.

     The yield fluctuates daily as the income earned on the investments of the
Portfolio fluctuates. Accordingly, there is no assurance that the yield quoted
on any given occasion will remain in effect for any period of time. It should
also be emphasized that the Portfolio is an open-end investment company and that
there is no guarantee that the net asset value will remain constant. A
shareholder's investment in the Portfolio is not insured. Investors comparing
results of the Portfolio with investment results and yields from other sources
such as banks or savings and loan associations should understand this
distinction. The yield quotation may be of limited use for comparative purposes
because it does not reflect charges imposed at the Account level which, if
included, would decrease the yield.

     Other portfolios of the money market type as well as banks and savings and
loan associations may calculate their yield on a different basis, and the yield
quoted by the Portfolio could vary upwards or downwards if another method of
calculation or base period were used.

OTHER INFORMATION

CUSTODY OF ASSETS -- All securities owned by the Portfolios and all cash,
including proceeds from the sale of shares of the Portfolios and of securities
in each Portfolio's investment portfolio, are held by State Street Bank and
Trust Company, 225 West Franklin Street, Boston, Massachusetts 02110, as
Custodian. With respect to investments in foreign securities, the custodian
enters into agreements with foreign sub-custodians which are approved by the
Trustees pursuant to Rule 17f-5 under the 1940 Act. The Custodian and
sub-custodians generally domestically, and frequently abroad, do not actually
hold certificates for the securities in their custody, but instead have book
records with domestic and foreign securities depositories, which in turn have
book records with the transfer agents of the issuers of the securities.

SHAREHOLDER REPORTS -- Semiannual statements of the Trust containing information
about each of the Portfolios, are furnished to shareholders, and annually such
statements are audited by the independent accountants whose selection is
ratified annually by shareholders.

INDEPENDENT ACCOUNTANTS -- PricewaterhouseCoopers LLP, 200 East Randolph Drive,
Chicago, Illinois 60601, the independent accountants for the Trust, performs an
annual audit of the Trust's financial statements.

LEGAL COUNSEL -- Skadden, Arps, Slate, Meagher & Flom (Illinois).

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

     See the prospectus and statement of additional information.

ITEM 25. INDEMNIFICATION.

     Reference is made to Article 8, Section 8.4 of the Registrant's Amended and
Restated Agreement and Declaration of Trust.

     Article 8; Section 8.4 of the Amended and Restated Agreement and
Declaration of Trust provides that each officer and trustee of the Registrant
shall be indemnified by the Registrant against all liabilities incurred in
connection with the defense or disposition of any action, suit or other
proceeding, whether civil or criminal, in which the officer or trustee may be or
may have been involved by reason of being or having been an officer or trustee,
except that such indemnity shall not protect any such person against a liability
to the Registrant or any shareholder thereof to which such person would
otherwise be subject by reason of (i) not acting in good faith in the reasonable
belief that such person's actions were not in the best interest of the Trust,
(ii) willful misfeasance, bad faith, gross negligence or reckless disregard of
the duties involved in the conduct of his or her office, (iii) for a criminal
proceeding, not having a reasonable cause to believe that such conduct was
unlawful (collectively "Disabling Conduct"). Absent a court determination that
an officer or trustee seeking indemnification was not liable on the merits or
guilty of Disabling Conduct in the conduct of his or her office, the decision by
the Registrant to indemnify such person must be based upon the reasonable
determination of independent counsel or non-party independent trustees, after
review of the facts, that such officer or trustee is not guilty of Disabling
Conduct in the conduct of his or her office.

                                       C-2
<PAGE>   213

     The Registrant has purchased insurance on behalf of its officers and
trustees protecting such persons from liability arising from their activities as
officers or trustees of the Registrant. The insurance does not protect or
purport to protect such persons from liability to the Registrant or to its
shareholders to which such officer or trustee would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of their office.

     Conditional advancing of indemnification monies may be made if the trustee
or officer undertakes to repay the advance unless it is ultimately determined
that he or she is entitled to the indemnification and only if the following
conditions are met: (1) the trustee or officer provides a security for the
undertaking; (2) the Registrant is insured against losses arising from lawful
advances; or (3) a majority of a quorum of the Registrant's disinterested,
non-party trustees, or an independent legal counsel in a written opinion, shall
determine, based upon a review of readily available facts, that a recipient of
the advance ultimately will be found entitled to indemnification.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to trustees, officers and controlling
persons of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in 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 the trustee, officer, or controlling person of the
Registrant in the successful defense of any action, suit or proceeding) is
asserted by such trustee, officer or controlling person in connection with the
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.
