      --------------------------------------------------------------------

The following questions and answers are designed to give you an overview of
SunAmerica Series Trust (the "Trust") and to provide you with information about
twenty-three of the Trust's separate investment series ("Portfolios") and their
investment goals and principal strategies. More complete investment information
is provided in the chart, under "More Information About the Portfolios," which
is on page 30, and the glossary that follows on page 42.

                                         Q&A

FIXED INCOME PORTFOLIOS typically seek to provide high current income consistent
with the preservation of capital by investing in fixed income securities.

YIELD is the annual dollar income received on an investment expressed as a
percentage of the current or average price.

INCOME is interest payments from bonds or dividends from stocks.

TOTAL RETURN is a measure of performance which combines all elements of return
including income and capital gain or loss; it represents the change in value of
an investment over a given period expressed as a percentage of the initial
investment.

"HIGH QUALITY" INSTRUMENTS have a very strong capacity to pay interest and repay
principal; they reflect the issuers' high creditworthiness and low risk of
default.

 
Q:  WHAT ARE THE PORTFOLIOS' INVESTMENT GOALS AND PRINCIPAL INVESTMENT
    STRATEGIES?
A:   Each Portfolio operates as a separate mutual fund, with its own investment
     goal and a principal strategy for pursuing it. A Portfolio's investment
     goal may be changed without shareholder approval, but you will be notified
     of any change. There can be no assurance that any Portfolio will meet its
     investment goal or that the net return on an investment will exceed what
     could have been obtained through other investment or savings vehicles.

BALANCED PORTFOLIOS typically try to balance three different investment goals:
capital appreciation, income and capital preservation by investing in a mixture
of stocks, bonds and money market instruments.
 
ASSET ALLOCATION is a varying combination, depending on market conditions and
risk level, of stocks, bonds, money market instruments and other assets.

CAPITAL APPRECIATION/GROWTH is an increase in the market value of securities
held.

A "GROWTH" PHILOSOPHY -- that of investing in securities believed to offer the
potential for capital appreciation -- focuses on securities of companies that
are considered to have an historical record of above- average growth rate,
significant growth potential, above-average earnings growth or value, the
ability to sustain earnings growth, or that offer proven or unusual products or
services, or operate in industries experiencing increasing demand.

A "VALUE" PHILOSOPHY -- that of investing in securities that are believed to be
undervalued in the market -- often reflects a contrarian approach in that the
potential for superior relative performance is believed to be highest when
fundamentally solid companies are out of favor. The selection criteria is
usually calculated to identify stocks of companies with solid financial strength
and generous dividend yields that have low price- earnings ratios and have
generally been overlooked by the market, or companies undervalued within an
industry or market capitalization category.

MARKET CAPITALIZATION represents the total market value of the outstanding
securities of a corporation.
 
INTERNATIONAL PORTFOLIOS typically seek capital appreciation by investing
significantly in securities traded in markets outside the U.S.

AN "EMERGING MARKET" COUNTRY is generally a country with a low or middle income
economy or that is in the early stages of its industrialization cycle.

Q:  WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE PORTFOLIOS?
 
A:  The following section describes the principal risks of each Portfolio, while
    the chart on page 31 describes various additional risks.
 
    Risks of Investing in Equity Securities
 
    The GROWTH-INCOME, FEDERATED VALUE, VENTURE VALUE, "DOGS" OF WALL STREET,
    ALLIANCE GROWTH, MFS GROWTH AND INCOME, PUTNAM GROWTH, REAL ESTATE, MFS
    MID-CAP GROWTH, AGGRESSIVE GROWTH, INTERNATIONAL GROWTH AND INCOME, GLOBAL
    EQUITIES, INTERNATIONAL DIVERSIFIED EQUITIES and EMERGING MARKETS PORTFOLIOS
    invest primarily in equity securities. In addition, the SUNAMERICA BALANCED,
    MFS TOTAL RETURN, ASSET ALLOCATION and UTILITY PORTFOLIOS invest
    significantly in equities. As with any equity fund, the value of your
    investment in any of these Portfolios may fluctuate in response to stock
    market movements. Growth stocks are historically volatile, which will
    particularly affect the GROWTH-INCOME, ALLIANCE GROWTH, MFS GROWTH AND
    INCOME, PUTNAM GROWTH, MFS MID-CAP GROWTH, AGGRESSIVE GROWTH and
    INTERNATIONAL GROWTH AND INCOME PORTFOLIOS. You should be aware that the
    performance of different types of equity stocks may rise or decline under
    varying market conditions -- for example, "value" stocks may perform well
    under circumstances in which "growth" stocks in general have fallen. In
    addition, individual stocks selected for any of these Portfolios may
    underperform the market generally.
 
    Risks of Investing in Bonds
 
    The CORPORATE BOND, GLOBAL BOND, HIGH-YIELD BOND, and WORLDWIDE HIGH INCOME
    PORTFOLIOS invest primarily in bonds. In addition, the SUNAMERICA BALANCED,
    MFS TOTAL RETURN, ASSET ALLOCATION and UTILITY PORTFOLIOS invest
    significantly in bonds. As with any bond fund, the value of your investment
    in these Portfolios may go up or down in response to changes in interest
    rates or defaults (or even the potential for future default) by bond
    issuers. To the extent a Portfolio is invested in the bond market, movements
    in the bond market generally may affect its performance.
 
    Risks of Investing in Junk Bonds
 
    The HIGH-YIELD BOND and WORLDWIDE HIGH INCOME PORTFOLIOS invest
    predominantly in junk bonds, which are considered speculative. The CORPORATE
    BOND, MFS TOTAL RETURN, ASSET ALLOCATION, ALLIANCE GROWTH, PUTNAM GROWTH,
    REAL ESTATE, MFS MID-CAP, INTERNATIONAL GROWTH AND INCOME and EMERGING
    MARKETS PORTFOLIOS may also invest in junk bonds. While the Adviser and
    Subadvisers each tries to diversify its portfolio and to engage in a credit
    analysis of each junk bond issuer in which it invests, junk bonds carry a
    substantial risk of default or changes in the issuer's creditworthiness, or
    they may already be in default. A junk bond's market price may fluctuate
    more than higher-quality securities and may decline significantly. In
    addition, it may be more difficult for a Portfolio to dispose of junk bonds
    or to determine their value. Junk bonds may contain redemption or call
    provisions that, if exercised during a period of declining interest rates,
    may force a Portfolio to replace the security with a lower yielding
    security. If this occurs, it will result in a decreased return for you.
 
    Risks of Investing in Money Market Securities
 
    While an investment in the CASH MANAGEMENT PORTFOLIO should present the
    least market risk of any of the Portfolios since it invests only in
    high-quality short-term debt obligations (money market securities), you
    should be aware that an investment in the CASH MANAGEMENT PORTFOLIO is
    subject to the risk that the value of its investments may be subject to
    changes in interest rates. The CASH MANAGEMENT PORTFOLIO does not seek to
    maintain a stable net asset value of $1.00.
 
    Risks of Investing Internationally
 
    Except for the Cash Management Portfolio, all of the Portfolios may invest
    internationally, including in "emerging market" countries. While investing
    internationally may reduce your risk by increasing the diversification of
    your investment, the value of your investment may be affected by fluctuating
    currency values, changing local and regional economic, political and social
    conditions, and greater market volatility, and, in addition, foreign
    securities may not be as liquid as domestic securities. These risks affect
    all the Portfolios except for the Cash Management Portfolio and are primary
    risks of the
 
                                        6
<PAGE>   7
 
    GLOBAL BOND, WORLDWIDE HIGH INCOME, INTERNATIONAL GROWTH AND INCOME, GLOBAL
    EQUITIES, INTERNATIONAL DIVERSIFIED EQUITIES and EMERGING MARKETS
    PORTFOLIOS.
 
    Risks of Investing in Smaller Companies
 
    Stocks of smaller companies may be more volatile than, and not as liquid as,
    those of larger companies. This will particularly affect the GROWTH-INCOME,
    ALLIANCE GROWTH, PUTNAM GROWTH, AGGRESSIVE GROWTH, INTERNATIONAL GROWTH AND
    INCOME and EMERGING MARKETS PORTFOLIOS.
 
    Risks of a "Passively Managed" Strategy
 
    Each of the "DOGS" OF WALL STREET and INTERNATIONAL DIVERSIFIED EQUITIES
    PORTFOLIOS will not deviate from its strategy (except to the extent
    necessary to comply with federal tax laws). If a Portfolio is committed to a
    strategy that is unsuccessful, the Portfolio will not meet its investment
    goal. Because the Portfolios will not use certain techniques available to
    other mutual funds to reduce stock market exposure, the Portfolios may be
    more susceptible to general market declines than other Portfolios.
 
    Risks of Investing in Utility Securities
 
    The UTILITY PORTFOLIO invests primarily in equity and debt securities of
    utility companies that produce, transmit, or distribute gas and electric
    energy as well as those companies that provide communications facilities,
    such as telephone and telegraph companies. Such utility securities entail
    certain risks including: (i) utility companies' historic difficulty in
    earning adequate returns on investment despite frequent rate increases; (ii)
    restrictions on operations and increased costs and delays due to
    governmental regulations; (iii) building or construction delays; (iv)
    environmental regulations; (v) difficulty of the capital markets in
    absorbing utility debt and equity securities; and (vi) difficulties in
    obtaining fuel at reasonable prices.
 
    To attempt to reduce these risks, the Subadviser will perform its own credit
    analysis in addition to using recognized rating agencies and will obtain
    information from other sources, including the issuer's management and other
    investment analysts.
 
    Risks of Investing in Real Estate Securities
 
    The REAL ESTATE PORTFOLIO invests primarily in the real estate industry. A
    Portfolio that invests primarily in the real estate industry is subject to
    the risks associated with the direct ownership of real estate. The Portfolio
    could also be subject to the risks of direct ownership as a result of a
    default on a debt security it may own. These risks include declines in the
    value of real estate, risks related to general and local economic
    conditions, overbuilding and increased competition, increases in property
    taxes and operating expenses, changes in zoning laws, casualty or
    condemnation losses, fluctuations in rental income, changes in neighborhood
    values, the appeal of properties to tenants and increases in interest rates.
    If the Portfolio has rental income or income from the disposition of real
    property, the receipt of such income may adversely affect its ability to
    retain its tax status as a regulated investment company. Most of the
    Portfolio's investments are, and likely will continue to be, interests in
    Real Estate Investment Trusts (REITs).
 
    Risks of Investing in "Non-Diversified" Portfolios
 
    The GLOBAL BOND, WORLDWIDE HIGH INCOME, "DOGS" OF WALL STREET, MFS MID-CAP
    GROWTH and INTERNATIONAL DIVERSIFIED EQUITIES PORTFOLIOS are organized as
    "non-diversified" Portfolios. A non-diversified Portfolio can invest a
    larger portion of assets in the securities of a single company than can some
    other mutual funds. By concentrating in a smaller number of securities, a
    Portfolio's risk is increased because the effect of each security on the
    Portfolio's performance is greater.
 
    Additional Principal Risks
 
    Shares of the Portfolios are not bank deposits and are not guaranteed or
    insured by any bank, government entity or the Federal Deposit Insurance
    Corporation. As with any mutual fund, there is no guarantee that a Portfolio
    will be able to achieve its investment goals. If the value of the assets of
    a Portfolio goes down, you could lose money.

Q:  HOW HAVE THE PORTFOLIOS PERFORMED HISTORICALLY?
 
A:  The following Risk/Return Bar Charts and Tables illustrate the risks of
    investing in the Portfolios by showing changes in the Portfolios'
    performance from calendar year to calendar year, and comparing the
    Portfolios' average annual returns to those of an appropriate market index.
    Fees and expenses incurred at the contract level are not reflected in the
    bar charts and tables. If these amounts were reflected, returns would be
    less than those shown. Of course, past performance is not necessarily an
    indication of how a Portfolio will perform in the future. The "DOGS" OF WALL
    STREET and the MFS MID-CAP GROWTH PORTFOLIOS have not been in existence for
    a full calendar year.

                              ACCOUNT INFORMATION
- --------------------------------------------------------------------------------
 
Shares of the Portfolios are not offered directly to the public. Instead, shares
are currently offered only to certain Separate Accounts of Anchor National Life
Insurance Company and First SunAmerica Life Insurance Company. So if you would
like to invest in a Portfolio, you must purchase a variable annuity contract
from either Anchor National Life Insurance Company or First SunAmerica Life
Insurance Company. You should be aware that the contracts involve fees and
expenses that are not described in this Prospectus and that the contracts also
may involve certain restrictions and limitations. Certain Portfolios may not be
available in connection with a particular contract. You will find information
about purchasing a variable annuity contract and the Portfolios available to you
in the prospectus that offers the contracts, which accompanies this Prospectus.
 
TRANSACTION POLICIES
 
VALUATION OF SHARES The net asset value per share (NAV) for each Portfolio is
determined each business day at the close of regular trading on the New York
Stock Exchange (generally 4:00 p.m., Eastern time) by dividing its net assets by
the number of its shares outstanding. Investments for which market quotations
are readily available are valued at market. All other securities and assets are
valued at "fair value" following procedures approved by the Trustees.
 
Certain of the Portfolios may invest to a large extent in securities that are
primarily listed on foreign exchanges that trade on weekends or other days when
the Trust does not price its shares. As a result, the value of these Portfolios'
shares may change on days when the Trust is not open for purchases or
redemptions.
 
BUY AND SELL PRICES The Separate Accounts buy and sell shares of a Portfolio at
NAV, without any sales or other charges.
 
EXECUTION OF REQUESTS The Trust is open on those days when the New York Stock
Exchange is open for regular trading. Buy and sell requests are executed at the
next NAV to be calculated after the request is accepted by the Trust. If the
order is received by the Trust before the Trust's close of business (generally
4:00 p.m., Eastern time), the order will receive that day's closing price. If
the order is received after that time, it will receive the next business day's
closing price.
 
During periods of extreme volatility or market crisis, a Portfolio may
temporarily suspend the processing of sell requests, or may postpone payment of
proceeds for up to seven business days or longer, as allowed by federal
securities laws.
 
DIVIDEND POLICIES AND TAXES
 
DISTRIBUTIONS Each Portfolio annually declares and distributes substantially all
of its net investment income in the form of dividends and capital gains
distributions.
 
DISTRIBUTION REINVESTMENT The dividends and distributions will be reinvested
automatically in additional shares of the same Portfolio on which they were
paid.
 
TAXABILITY OF A PORTFOLIO Each Portfolio intends to continue to qualify as a
regulated investment company under the Internal Revenue Code of 1986, as
amended. As long as each Portfolio is qualified as a regulated investment
company, it will not be subject to federal income tax on the earnings that it
distributes to its shareholders.

        ADDITIONAL INFORMATION ABOUT THE "DOGS" OF WALL STREET PORTFOLIO
- --------------------------------------------------------------------------------
 
INVESTMENT STRATEGY FOR THE "DOGS" OF WALL STREET PORTFOLIO
 
The "DOGS" OF WALL STREET PORTFOLIO employs a passively managed "buy and hold"
strategy that annually selects the following 30 stocks: (1) the 10 highest
yielding common stocks in the Dow Jones Industrial Average and (2) the 20 other
highest yielding stocks of the 400 largest industrial companies in the U.S.
markets that have capitalizations of at least $1 billion and have received one
of the two highest rankings from an independently published common stock ranking
service on the basis of growth and stability of earnings and dividends. The
stocks in the Portfolio will not change over the course of the year, even if
there are adverse developments concerning a particular stock, an industry, the
economy or the stock market generally. The annual selection of the thirty stocks
that meet these criteria takes place no later than January 15th, on the basis of
information as of the preceding December 31st. Immediately after the Portfolio
buys and sells stocks, it will hold an equal value of each of the thirty stocks.
In other words, the Portfolio will invest 1/30 of its assets in each of the
stocks that make up its portfolio. Thereafter, when an investor purchases shares
of the Portfolio, the Adviser invests the additional funds in the selected
stocks based on each stock's respective percentage of the Portfolio's assets.
Due to purchases and redemptions of Portfolio shares during the year and changes
in the market value of the stocks held by the Portfolio, it is likely that the
weightings of the stocks in the Portfolio will fluctuate throughout the course
of the year. This may result in the Portfolio investing more than 25% of its
assets in the securities of issuers in the same industry, to the extent such
investments are selected according to the Portfolio's stock selection criteria.

INVESTMENT TERMINOLOGY
 
LARGE COMPANIES generally have market capitalizations of over $5 billion,
although there may be some overlap among capitalization categories.
 
MEDIUM SIZED COMPANIES generally have market capitalizations ranging from $1
billion to $5 billion, although there may be some overlap among capitalization
categories. With respect to the MFS MID-CAP GROWTH PORTFOLIO, the Subadviser
will consider companies with market capitalizations equaling or exceeding $250
million but not exceeding the top range of the Russell MidCap(TM) Growth Index
to be medium sized companies.
 
SMALL COMPANIES generally have market capitalizations of $1 billion or less,
although there may be some overlap among capitalization categories.
 
ACTIVE TRADING means that a Portfolio may engage in frequent trading of
portfolio securities to achieve its investment goal. In addition, because a
Portfolio may sell a security without regard to how long it has held the
security, active trading may have tax consequences for certain shareholders,
involving a possible increase in short-term capital gains or losses. Active
trading may result in high portfolio turnover and correspondingly greater
brokerage commissions and other transaction costs, which will be borne directly
by a Portfolio. During periods of increased market volatility, active trading
may be more pronounced. In the "Financial Highlights" section we provide each
Portfolio's portfolio turnover rate for each of the last five years.
 
The Fund may BORROW FOR TEMPORARY OR EMERGENCY PURPOSES including to meet
redemptions. Borrowing will cost the Fund interest expense and other fees.
 
FIXED INCOME SECURITIES provide consistent interest or dividend payments. They
include corporate bonds, notes, debentures, preferred stocks, convertible
securities, U.S. government securities and mortgage-backed and asset-backed
securities. The issuer of a SENIOR fixed income security is obligated to make
payments on this security ahead of other payments to security holders.
 
An INVESTMENT GRADE fixed income security is rated in one of the top four rating
categories by a debt rating agency (or is considered of comparable quality by
the Adviser or Subadviser). The two best-known debt rating agencies are Standard
& Poor's Rating Services, a Division of the McGraw-Hill Companies, Inc. and
Moody's Investors Service, Inc. INVESTMENT GRADE refers to any security rated
"BBB" or above by Standard & Poor's or "Baa" or above by Moody's.
 
A JUNK BOND is a high yield, high risk bond that does not meet the credit
quality standards of investment grade securities.
 
U.S. GOVERNMENT SECURITIES are issued or guaranteed by the U.S. government, its
agencies and instrumentalities. Some U.S. government securities are issued or
unconditionally guaranteed by the U.S. Treasury. They are of the highest
possible credit quality. While these securities are subject to variations in
market value due to fluctuations in interest rates, they will be paid in full if
held to maturity. Other U.S. government securities are neither direct
obligations of, nor guaranteed by, the U.S. Treasury. However, they involve
federal sponsorship in one way or another. For example, some are backed by
specific types of collateral; some are supported by the issuer's right to borrow
from the Treasury; some are supported by the discretionary authority of the
Treasury to purchase certain obligations of the issuer; and others are supported
only by the credit of the issuing government agency or instrumentality.
 
PASS-THROUGH SECURITIES involve various debt obligations that are backed by a
pool of mortgages or other assets. Principal and interest payments made on the
underlying asset pools are typically passed through to investors. Types of
pass-through securities include "mortgage-backed securities," "collateralized
mortgage obligations," "commercial mortgage-backed securities," and
"asset-backed securities."

CONVERTIBLE SECURITIES are securities (such as bonds or preferred stocks) that
may be converted into common stock of the same or a different company.
 
PREFERRED STOCK is a class of capital stock that pays dividends at a specified
rate and that has preference over common stock in the payment of dividends and
the liquidation of assets.
 
SMALL COMPANY STOCKS are stocks of companies that generally have a
capitalization of under $1 billion.
 
HYBRID INSTRUMENTS, such as INDEXED (i.e., Standard and Poor's Depositary
Receipts and World Equity Benchmark Shares) and STRUCTURED SECURITIES, can
combine the characteristics of securities, futures, and options. For example,
the principal amount, redemption, or conversion terms of a security could be
related to the market price of some commodity, currency, or securities index.
Such securities may bear interest or pay dividends at below market (or even
relatively nominal) rates. Under certain conditions, the redemption value of
such an investment could be zero.
 
WARRANTS are rights to buy common stock of a company at a specified price during
the life of the warrant. RIGHTS represent a preemptive right of stockholders to
purchase additional shares of a stock at the time of a new issuance before the
stock is offered to the general public.
 
SHORT-TERM INVESTMENTS include money market securities such as short-term U.S.
government obligations, repurchase agreements, commercial paper, bankers'
acceptances and certificates of deposit. These securities provide a Portfolio
with sufficient liquidity to meet redemptions and cover expenses.
 
DEFENSIVE INVESTMENTS include high quality fixed income securities, repurchase
agreements and other money market instruments. A Portfolio will make temporary
defensive investments in response to adverse market, economic, political or
other conditions. When a Portfolio takes a defensive position, it may miss out
on investment opportunities that could have resulted from investing in
accordance with its principal investment strategy. As a result, a Portfolio may
not achieve its investment goal.
 
EQUITY SWAPS are exchanges of the total return on a stock for the total return
on another asset, usually a diversified equity or fixed income index.
 
FOREIGN SECURITIES are issued by companies located outside of the United States,
including emerging markets. Foreign securities may include American Depositary
Receipts (ADRs) or other similar securities that convert into foreign
securities.
 
CURRENCY TRANSACTIONS include the purchase and sale of currencies to facilitate
securities transactions and forward currency contracts, which are used to hedge
against changes in currency exchange rates.
 
ILLIQUID SECURITIES are subject to legal or contractual restrictions that may
make them difficult to sell. A security that cannot easily be sold within seven
days will generally be considered illiquid. Certain restricted securities (such
as Rule 144A securities) are not generally considered illiquid because of their
established trading market.
 
OPTIONS AND FUTURES are contracts involving the right to receive or the
obligation to deliver assets or money depending on the performance of one or
more underlying assets or a market or economic index.
 
FORWARD COMMITMENTS are commitments to purchase or sell securities at a future
date. A Portfolio purchasing a forward commitment assumes the risk of any
decline in value of the securities beginning on the date of the agreement.
 
DOLLAR ROLLS are instruments in which a Portfolio sells mortgage or other
asset-backed securities ("Roll Securities") for delivery in the current month
and simultaneously contracts to repurchase substantially similar (same type,
coupon and maturity) securities on a specified future date.
 
REITS (real estate investment trusts) are trusts that invest primarily in
commercial real estate or real estate related loans. The value of an interest in
a REIT may be affected by the value and the cash flows of the properties owned
or the quality of the mortgages held by the trust.
 
A Portfolio may invest in OTHER REGISTERED INVESTMENT COMPANIES, which are
registered in accordance with the federal securities laws.
 
                                       43

ZERO-COUPON AND DEFERRED INTEREST BONDS are debt obligations that are issued or
purchased at a significant discount from face value. PAY-IN-KIND BONDS are debt
obligations that provide that the issuer thereof may, at its option, pay
interest on such bonds in cash or in the form of additional debt obligations.
Such investments may experience greater volatility in market value due to
changes in interest rates than do debt obligations.
 
FIRM COMMITMENT AGREEMENTS and WHEN-ISSUED or DELAYED-DELIVERY TRANSACTIONS call
for the purchase or sale of securities at an agreed-upon price on a specified
future date. At the time of delivery of the securities, the value may be more or
less than the purchase price.
 
INTEREST RATE SWAPS, CAPS, FLOORS AND COLLARS Interest rate swaps involve the
exchange by a Portfolio with another party of their respective commitments to
pay or receive interest, such as an exchange of fixed-rate payments for floating
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 payment of interest on a notional principal amount from the party
selling such 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 notional principal amount
from the party selling the interest rate floor. An interest rate collar is the
combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates.
 
SECURITIES LENDING involves a loan of securities by a Portfolio in exchange for
cash or collateral. A Portfolio earns interest on the loan while retaining
ownership of the security.
 
By purchasing a LOAN PARTICIPATION, a Portfolio acquires some or all of the
interest of a bank or other lending institution in a loan to a corporate
borrower. The highly leveraged nature of many such loans may make such loans
especially vulnerable to adverse changes in economic or market conditions. As a
result, a Portfolio may be unable to sell such investments at an opportune time
or may have to resell them at less than fair market value.
 
RISK TERMINOLOGY
 
MARKET VOLATILITY:  The stock and/or bond markets as a whole could go up or down
(sometimes dramatically). This could affect the value of the securities in a
Portfolio's portfolio.
 
SECURITIES SELECTION:  A strategy used by a Portfolio, or securities selected by
its portfolio manager, may fail to produce the intended return.
 
PASSIVELY MANAGED STRATEGY:  A Portfolio following a passively managed strategy
will not deviate from its investment strategy. In the case of "DOGS" OF WALL
STREET PORTFOLIO, this entails buying and holding thirty stocks selected through
objective selection criteria (except to the extent necessary to comply with
applicable federal tax laws). In other cases, it may involve a passively managed
strategy utilized to achieve investment results that correspond to a particular
market index. Such a Portfolio will not sell stocks in its portfolio and buy
different stocks over the course of a year, even if there are adverse
developments concerning a particular stock, company or industry. There can be no
assurance that the strategy will be successful.
 
INTEREST RATE FLUCTUATIONS:  Volatility of the bond market is due principally to
changes in interest rates. As interest rates rise, bond prices typically fall;
and as interest rates fall, bond prices typically rise. Longer-term and lower
coupon bonds tend to be more sensitive to changes in interest rates.
 
CREDIT QUALITY:  The creditworthiness of the issuer is always a factor in
analyzing fixed income securities. An issuer with a lower credit rating will be
more likely than a higher rated issuer to default or otherwise become unable to
honor its financial obligations. This type of issuer will typically issue JUNK
BONDS. In addition to the risk of default, junk bonds may be more volatile, less
liquid, more difficult to value and more susceptible to adverse economic
conditions or investor perceptions than other bonds.
 
PREPAYMENT:  Prepayment risk is the possibility that the principal of the loans
underlying mortgage-backed or other pass-through securities may be prepaid at
any time. As a general rule, prepayments increase during a period of falling
interest rates and decrease during a period of rising interest rates. As a
 
                                       44
<PAGE>   45
 
result of prepayments, in periods of declining interest rates a Portfolio may be
required to reinvest its assets in securities with lower interest rates. In
periods of increasing interest rates, prepayments generally may decline, with
the effect that the securities subject to prepayment risk held by a Portfolio
may exhibit price characteristics of longer-term debt securities.
 
FOREIGN EXPOSURE:  Investors in foreign countries are subject to a number of
risks. A principal risk is that fluctuations in the exchange rates between the
U.S. dollar and foreign currencies may negatively affect an investment. In
addition, there may be less publicly available information about a foreign
company and it may not be subject to the same uniform accounting, auditing and
financial reporting standards as U.S. companies. Foreign governments may not
regulate securities markets and companies to the same degree as in the U.S.
Foreign investments will also be affected by local political or economic
developments and governmental actions. Consequently, foreign securities may be
less liquid, more volatile and more difficult to price than U.S. securities.
These risks are heightened when an issuer is in an EMERGING MARKET.
 
NON-DIVERSIFICATION:  By concentrating in a smaller number of securities, a
Portfolio's risk is increased because the effect of each stock on the
Portfolio's performance is greater.
 
EURO CONVERSION:  Effective January 1, 1999, several European countries
irrevocably fixed their existing national currencies to a new single European
currency unit, the "euro." Certain European investments may be subject to
additional risks as a result of this conversion. These risks include adverse tax
and accounting consequences, as well as difficulty in processing transactions.
SAAMCo is aware of such potential problems and is coordinating efforts to
prevent or alleviate their adverse impact on the Portfolios. There can be no
assurance that a Portfolio will not suffer any adverse consequences as a result
of the euro conversion.
 
EMERGING MARKETS:  An emerging market country is generally a country with a low
or middle income economy or that is in the early stages of its industrialization
cycle. Emerging market countries may change over time depending on market and
economic conditions and the list may vary by advisor. The risks attendant to
foreign exposure are heightened in an emerging market country. Historical
experience indicates that the markets of emerging countries have been more
volatile than more developed markets; however, such markets can provide higher
rates of return to investors.
 
SMALL MARKET CAPITALIZATION:  Companies with smaller market capitalizations
(particularly under $1 billion) tend to be at early stages of development with
limited product lines, market access for products, financial resources, access
to new capital, or depth in management. Consequently, the securities of smaller
companies may not be as readily marketable and may be subject to more abrupt or
erratic market movements.
 
ILLIQUIDITY:  Certain securities may be difficult or impossible to sell at the
time and the price that the seller would like.
 
REAL ESTATE INDUSTRY:  Risks include declines in the value of real estate, risks
related to general and local economic conditions, overbuilding and increased
competition, increases in property taxes and operating expenses, changes in
zoning laws, casualty or condemnation losses, fluctuations in rental income,
changes in neighborhood values, the appeal of properties to tenants and
increases in interest rates. If the Portfolio has rental income or income from
the disposition of real property, the receipt of such income may adversely
affect its ability to retain its tax status as a regulated investment company.
In addition, REITs are dependent upon management skill, may not be diversified
and are subject to project financing risks. Such trusts are also 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
Internal Revenue Code of 1986, as amended, and to maintain exemption from
registration under the laws governing mutual funds.
 
UTILITY INDUSTRY:  Risks include (i) utility companies' difficulty in earning
adequate returns on investment despite frequent rate increases; (ii)
restrictions on operations and increased costs and delays due to governmental
regulations; (iii) building or construction delays; (iv) environmental
regulations; (v) difficulty of the capital markets in absorbing utility debt and
equity securities; and (vi) difficulties in obtaining fuel at reasonable prices.
 
                                       45
<PAGE>   46
 
DERIVATIVES:  A derivative is any financial instrument whose value is based on,
and determined by, another security, index or benchmark (i.e., stock options,
futures, caps, floors, etc.). In recent years, derivative securities have become
increasingly important in the field of finance. Futures and options are now
actively traded on many different exchanges. Forward contracts, swaps, and many
different types of options are regularly traded outside of exchanges by
financial institutions in what are termed "over the counter" markets. Other more
specialized derivative securities often form part of a bond or stock issue. To
the extent a contract is used to hedge another position in the portfolio, there
is a risk that changes in the value of the contract will not match those of the
hedged position. Moreover, while hedging can reduce or eliminate losses, it can
also reduce or eliminate gains. To the extent an option or futures contract is
used to enhance return, rather than as a hedge, a Portfolio will be directly
exposed to the risks of the contract. Gains or losses from non-hedging positions
may be substantially greater than the cost of the position.
 
HEDGING:  Hedging is a strategy in which a Portfolio uses a derivative security
to reduce certain risk characteristics of an underlying security or portfolio of
securities. While hedging strategies can be very useful and inexpensive ways of
reducing risk, they are sometimes ineffective due to unexpected changes in the
market. Hedging also involves the risk that changes in the value of the
derivative will not match those of the instruments being hedged as expected, in
which case any losses on the instruments being hedged may not be reduced.
Examples of hedging strategies are:
 
     - Long Hedge -- Strategy in which an investor locks in a future price on a
       security/index by buying a futures contract.
 
     - Neutral Hedge -- Strategy that is designed to provide the highest
       expected return on a portfolio of securities assuming that the price of a
       particular investment in the portfolio remains constant.
 
     - Perfect Hedge -- a hedge whose change in value is equal to the change in
       value of the underlying security, positive or negative.
 
     - Short Hedge -- Strategy designed to reduce the risk of a decline in value
       of a security/index without requiring ownership of that security.

YEAR 2000
 
Many computer and computer-based systems cannot distinguish the year 2000 from
the year 1900 because of the way they encode and calculate dates (commonly known
as the "Year 2000 Issue"). The Year 2000 Issue could potentially have an adverse
impact on the handling of security trades, the payment of interest and
dividends, pricing and account services. We recognize the importance of the Year
2000 Issue and are taking appropriate steps necessary in preparation for the
year 2000. The Trust's management fully anticipates that their systems will be
adapted in time for the year 2000, and to further this goal they have
coordinated a plan to repair, adapt or replace their systems as necessary. They
have also obtained representations from their outside service providers that
they are doing the same. The Trust's management completed their plan
significantly by the end of the 1998 calendar year and expects to perform
appropriate systems testing during the 1999 calendar year. If the problem has
not been fully addressed, however, the Trust could be negatively impacted. The
Year 2000 Issue could also have a negative impact on the companies in which the
Trust invests, which could hurt the Trust's investment returns.
