WELCOME

Unless otherwise specified in this prospectus, the words we, our, and VALIC mean
The Variable Annuity Life Insurance Company and any Investment Sub-adviser that
we work with. The words you and your mean the participant.
 
American General Series Portfolio Company 3 (the "Series Company") was organized
as a Delaware business trust on May 6, 1998.
 
The Series Company is an open-end management investment company and currently
consists of 18 different Funds, each of which is described in detail in this
prospectus. We serve as each Fund's Investment Adviser and, in this role, report
directly to the Series Company's Board of Trustees. As Investment Adviser, we
oversee the Funds' day to day operations and supervise the purchase and sale of
Fund investments. However, we make investment decisions for, and are directly
responsible for the day to day management of, the Socially Responsible Fund, the
Money Market Fund and the Lifestyle Funds. For more information, see "About the
Funds' Management" in this prospectus.
 
Individuals can't invest in the shares of these Funds directly. Instead, they
participate through an annuity or variable life contracts or employer plan with
VALIC or one of its affiliates, or employee thrift plans maintained by VALIC or
American General Corporation. Most often employers set up these contracts so
they can offer their employees a way to save for retirement. Retirement plans
through employers may be entitled to tax benefits that individual retirement
plans may not be entitled to. These tax benefits are fully explained in your
contract prospectus.
 
After you invest in a Fund, you participate in Fund earnings or losses, in
proportion to the amount of money you invest. Depending on your contract, if you
withdraw your money before retirement, you may incur charges and additional tax
liabilities. However, to save for retirement, you generally should let your
investments and their earnings build. At retirement, you may withdraw all or a
portion of your money, leave it in the account until you need it, or start
receiving annuity payments. At a certain age you may be required to begin
withdrawals.
 
All inquiries regarding this prospectus should be directed, in writing, to VALIC
Customer Service, A3-01, 2929 Allen Parkway, Houston, Texas 77019, or by calling
1-800-633-8960.
 
All inquiries regarding contracts issued by American General Life Insurance
Company (AGL) should be directed to AGL's Annuity Administration Department,
2727-A Allen Parkway, Houston, Texas 77019-2191 or call (800) 813-5065. AGL is a
member of the American General Corporation group of companies, as is VALIC.
 
Open-end means shares
of the Funds can be
bought or sold by the
Series Company at any
time. Also, there is no limit
on the number of investors
who may buy shares.

EXPENSE SUMMARY

Annual fund operating expenses are the fees paid out of the assets of a Fund.
Each Fund pays a management fee to VALIC. The expenses paid by a Fund are
factored into the calculation of its share price or dividends and are not
charged directly to investors. The expenses reflected in the tables below are
based on the Funds' estimated expenses for the first year of operation on an
annualized basis.

PORTFOLIO MANAGER
 
A manager is a person or team of persons VALIC or one of its Sub-advisers, has
assigned to be primarily responsible for the day to day management of a Fund's
investments. A Fund's investments are called its portfolio.
 
HOW ADVISERS ARE PAID FOR
THEIR SERVICES
 
VALIC
 
Each Fund pays VALIC a fee based on its average daily net asset value. A Fund's
net asset value is the total value of the Fund's assets minus any money it owes
for operating expenses, such as the fee paid to its Custodian to safeguard the
Fund's investments.
 
Here is a list of the percentages each Fund pays VALIC.

</TABLE>
 
The Investment Advisory Agreement we entered into with each Fund does not limit
how much the Funds pay in monthly expenses each year. However, we voluntarily
limit the Funds' monthly expenses as follows:
 
  If a Fund's average monthly expenses, when annualized, are more than [.96%] of
  the Fund's estimated average daily net assets, we will pay the difference. As
  a result the Fund's yield or total return will increase. If VALIC decides to
  stop voluntarily reducing a Fund's expenses, it may do so by giving 30 days'
  notice, in writing, to the Series Company.
 
As shareholders of other Series Company Funds, the Lifestyle Funds incur their
proportionate share of the underlying Series Company Funds' fees and expenses,
including the fees paid to VALIC.

THE SUB-ADVISERS
 
According to the agreements we have with the Sub-advisers, we pay them directly
out of the fee we receive from the Funds. The Funds do not pay the Sub-advisers
directly. We pay them a percentage of what is paid to us by the Funds. We and
the Sub-advisers may agree to change the amount of money we pay them. Any such
change increasing the charge paid by the Fund to VALIC would have to be approved
by the Series Company Board of Trustees and the shareholders of the Fund.
 
The Series Company was issued an exemptive order by the Securities and Exchange
Commission (the "SEC") on          , 1998 for an exemption (the "Exemption")
from certain provisions of the Investment Company Act of 1940 ("1940 Act") which
would otherwise require VALIC to obtain formal shareholder approval prior to
engaging and entering into sub-advisory agreements with Sub-advisers. The relief
is based on the conditions set forth in the Exemption that, among other things:
(1) VALIC will select, monitor, evaluate and allocate assets to the Sub-advisers
and oversee Sub-advisers compliance with the relevant Fund's investment
objective, policies and restrictions; (2) before a Fund may rely on the
Exemption, the Exemption must be approved by the shareholders of the Funds
operating under the Exemption; (3) the Series Company will provide to
shareholders certain information about a new Sub-adviser; (4) the Series Company
will disclose in this Prospectus the existence, substance and effect of the
Exemption; and (5) the Trustees, including a majority of the "independent"
Trustees, must approve each sub-advisory agreement in the manner required under
the 1940 Act. Any changes to the Investment Advisory Agreement between the
Series Company and VALIC would still require shareholder approval. As required
by the Exemption, the shareholders of each Fund determined, at a shareholders'
meeting held on          , 1998, to permit the Series Company to replace or add
Sub-advisers and to enter into sub-advisory agreements with Sub-advisers upon
approval of the Board of Trustees but without formal shareholder approval.
 
Under the Investment Sub-Advisory Agreement we have with Bankers Trust, we pay
Bankers Trust monthly fees based on the average daily net asset values of the
portion of the Small Cap Value Fund portfolio it manages at an annual rate of
0.03% and the S&P 500 Index Fund at an annual rate of 0.02% of the first $2
billion and 0.01% on assets over $2 billion. We pay Bankers Trust monthly fees
based on the average daily net asset values of the Mid Cap Index Fund at an
annual rate of 0.03% of the first $300 million and 0.02% on assets over $300
million and the Small Cap Index Fund at an annual rate of 0.03% of the first
$150 million and 0.02% on assets over $150 million.
 
Under the Investment Sub-Advisory Agreement we have with Brown Capital
Management, we pay Brown Capital Management a monthly fee based on the average
daily net asset values of the Mid Cap Growth Fund at the annual rate of 0.40% of
the first $25 million, 0.30% of the next $25 million and 0.20% on assets over
$50 million.
 
   
Under the Investment Sub-Advisory Agreement we have with Capital Guardian, we
pay Capital Guardian a monthly fee based on the average daily net asset values
of the International Value Fund at an annual rate of 0.75% of the first $25
million, 0.60% of the next $25 million, 0.425% of the next $200 million and
0.375% on assets over $250 million and the Domestic Bond Fund at an annual rate
of 0.35% of the first $50 million, 0.20% on the next $50 million, 0.18% on the
next $200 million and 0.15% of assets over $300 million. We pay Capital Guardian
monthly fees based on the average daily net asset values of the Balanced Fund at
an annual rate of 0.55% of the first $25 million, 0.40% of the next $25 million
and 0.20% on assets over $50 million. Capital Guardian aggregates fees with
respect to the International Value Fund, the Domestic Bond Fund and the Balanced
Fund and applies a 5% discount to fees between $1.25 million and $4 million, a
7.5% discount to fees from $4 million to $8 million, a 10% discount to fees
between $8 million and $12 million, and a 12.5% discount to fees exceeding $12
million.
    
 
Under the Investment Sub-Advisory Agreement we have with FMA, we pay FMA a
monthly fee based on the average daily net asset values of the portion of the
Small Cap Value Fund portfolio it manages at the annual rate of 0.50% of the
first $50 million and 0.40% on assets over $50 million.
 
Under the Investment Sub-Advisory Agreement we have with GSAM, we pay GSAM a
monthly fee based on the average daily net asset values of the Large Cap Growth
Fund at the annual rate of 0.30%.
 
Under the Investment Sub-Advisory Agreement we have with JP Morgan, we pay JP
Morgan a monthly fee based on the average daily net asset values of the Small
Cap Growth Fund at the annual rate of 0.60%.

Management, we pay Jacobs Asset Management a monthly fee based on the average
daily net asset values of the International Growth Fund at an annual rate of
0.65% of the first $100 million and 0.55% on assets over $100 million.

Under the Investment Sub-Advisory Agreement we have with N&B Management, we pay
N&B Management a monthly fee based on the average daily net asset values of the
Mid Cap Value Fund at the annual rate of 0.50% of the first $100 million, 0.475%
of the next $150 million, 0.45% of the next $250 million, 0.425% of the next
$250 million and 0.40% on assets over $750 million.
 
Under the Investment Sub-Advisory Agreement we have with State Street Global
Advisers, we pay State Street Global Advisers a monthly fee based on the average
daily net asset values of the Large Cap Value Fund at the annual rate of 0.25%
but no less than $50,000 per year.
 
According to the agreements we have with the Sub-advisers, we will receive
investment advice for each sub-advised Fund. Under these agreements we give the
Sub-advisers the authority to buy and sell securities for these Funds. We retain
the responsibility for the overall management of these Funds. The Sub-advisers
may buy and sell securities for each Fund with broker-dealers and other
financial intermediaries that they select.
 
The Sub-advisers may place orders to buy and sell securities of these Funds with
a broker-dealer affiliated with the Sub-adviser as allowed by law. This could
include any affiliated futures commission merchants.
 
The 1940 Act permits Sub-advisers under certain conditions to place an order to
buy or sell securities with an affiliated broker. One of these conditions is
that the commission received by the affiliated broker can not be greater than
the usual and customary brokers commission if the sale was completed on a
securities exchange. The Series Company has adopted procedures, as required by
the 1940 Act, which provide that any commissions received by a Sub-adviser's
affiliated broker are reasonable and fair if compared to the commission received
by other brokers for the same type of securities transaction.
 
The Securities Exchange Act of 1934 prohibits members of national securities
exchanges from effecting exchange transactions for accounts that they or their
affiliates manage, except as allowed under rules adopted by the SEC. The Series
Company and the Sub-advisers have entered into a written contract, as required
by the 1940 Act, to allow the Sub-adviser's affiliate to effect these type of
transactions for commissions. The 1940 Act generally prohibits a Sub-adviser or
a Sub-adviser's affiliate, acting as principal, from engaging in securities
transactions with a Fund, without an exemptive order from the SEC.
 
We and the Sub-advisers may enter into simultaneous purchase and sale
transactions for the Funds or affiliates of the Funds.
 
ABOUT THE BOARD OF TRUSTEES
 
The Series Company Board of Trustees currently consists of eleven members: eight
are independent Trustees and three are VALIC employees.
 
The Board of Trustees may change each Fund's investment objective, investment
policies and non-fundamental investment restrictions without shareholder
approval. The Board may not change any fundamental restrictions placed on the
types of investments each Fund may buy. The fundamental restrictions appear in
the Statement of Additional Information. Changes to these restrictions may be
made with shareholder approval only.

ABOUT THE FUNDS
- --------------------------------------------------------------------------------
 
GROWTH, BALANCED, INCOME AND STABILITY CATEGORIES
 
The Funds offered in this prospectus fall into five general investment
categories: growth, balanced, income, stability and lifestyle.
 
Growth Category
 
The goal of a Fund in the growth category is to increase the value of your
investment over the long term by investing mostly in stocks. Stocks are a type
of investment that can increase in value over a period of years. Companies sell
stock to get the money they need to grow. These companies often keep some of
their profits to reinvest in their business. As they grow, the value of their
stock may increase. This is how the value of your investment may increase.
 
Series Company Growth Category includes:
 
  S&P 500 Index Fund
  Mid Cap Index Fund
  Small Cap Index Fund
  International Growth Fund
  Large Cap Growth Fund
  Mid Cap Growth Fund
  Small Cap Growth Fund
  International Value Fund
  Large Cap Value Fund
  Mid Cap Value Fund
  Small Cap Value Fund
  Socially Responsible Fund
 
Balanced Fund
 
The goal of a Fund in the balanced category is to increase the value of your
investment over the long term and to provide income. Funds in the balanced
category seek to conserve the value of your initial investment and promote
long-term growth and income by investing in stocks and income producing
securities.
 
Series Balanced Category includes:
 
  Balanced Fund
 
Income Category
 
Unlike Funds in the growth category, where the objective is to make the Fund's
investments increase in value, Funds in the income category try to keep the
value of their investments from falling, while providing an increase in the
value of your investment through the income earned on the Fund's investments. To
meet this objective, Funds in the income category buy investments that are
expected to pay interest to the Fund on a regular basis.
 
Series Company Income Category includes:
 
  Domestic Bond Fund
 
Stability Category
 
Funds in the stability category provide liquidity, protection of capital and
current income through investments in high quality securities.
 
Series Company Stability Category includes:
 
  Money Market Fund
 
LIFESTYLE CATEGORY
 
A Fund in the lifestyle category may invest in up to twelve Series Company
Funds. A Lifestyle Fund does not invest directly in portfolio securities but,
rather, invests in a combination of Series Funds in order to meet its investment
objective. In this manner, the Lifestyle Funds offer you the opportunity to
diversify your investment portfolio by investing in one Fund, rather than in a
variety of Series Company Funds.
 
Series Company Lifestyle Category includes:
 
  Growth Lifestyle Fund
  Moderate Growth Lifestyle Fund
  Conservative Growth Lifestyle Fund
 
ABOUT LEVEL OF RISK
 
The risks involved in each Fund are described in each Fund's Fact Sheet. These
risks may include market risk, credit risk, interest rate risk and risk
associated with foreign securities. These risks are described in the "Types of
Investments" section in this prospectus. The money you invest in the Series
Company is not insured. And, we can't guarantee that any of the Funds will meet
their investment objectives. There's a chance you may lose money and end up with
less than you invested.
 
ABOUT PORTFOLIO TURNOVER
 
Portfolio turnover occurs when a Fund sells its investments and buys new ones.
In some Funds, high portfolio turnover occurs when these Funds sell and buy
investments as part of their investment strategy. In other Funds, like the Index
Funds discussed below, portfolio turnover is lower because the make up of the
index stays fairly constant.
 
High portfolio turnover may cause a fund's expenses to increase. For example, a
fund may have to pay brokerage fees and other related expenses.

</TABLE>
 
A portfolio turnover rate over 100% a year is higher than the rates of many
other mutual fund companies. A high rate increases a Fund's transaction costs
and expenses.
 
ABOUT FUND PERFORMANCE
 
From time to time the Series Company may advertise Fund performance information
such as Fund average total return and index total return. Information as to how
this Fund performance information is calculated appears in the Statement of
Additional Information. Additionally, information on separate account
performance appears in your contract prospectus.

THE INDEX EQUITY FUNDS
- --------------------------------------------------------------------------------
 
Three of the 18 Funds in the Series Company are Index Equity Funds investing
mostly in stocks. Their investment strategy is to track the performance of a
specific index. This strategy is followed whether markets go up or down. As part
of this investment strategy, each Fund may also invest in futures contracts and
options. Because these Funds do not have a defensive investment strategy, when
the market goes down, you will bear the risk of such market decline.
 
Index Funds perform best over the long term. This means you should plan to keep
your money in an Index Fund for a period of years.
 
WHAT IS AN INDEX?
 
An index reflects the average performance of a particular class of securities.
Examples of indexes include large company stocks (S&P 500 Index), mid-size
company stocks (S&P Mid Cap 400 Index), the bond market, or stocks of companies
in specific industries. Indexes are not managed funds, and cannot be bought.
Investment advisers compare the results of the funds they manage to indexes that
are close to the investment style of the fund. Information about the Series
Company's use of Standard & Poor's Indexes is in the Statement of Additional
Information.
 
WHICH INDEXES DO THESE FUNDS TRY TO TRACK?
 
While there are more than a hundred different indexes, the Index Funds in this
prospectus try to track three very prominent stock indexes:
 
THE S&P 500 INDEX FUND TRACKS THE STANDARD & POOR'S 500 STOCK INDEX(R)*
 
The Standard & Poor's 500 Stock Index(R) (S&P 500) tracks the common stock
performance of large U.S. manufacturing, utilities, transportation, and
financial companies as well as companies in other industries. These companies
are usually listed on the New York Stock Exchange. It also tracks performance of
common stocks sold by foreign and smaller U.S. companies in similar industries.
The smaller U.S. companies are usually listed on the American Stock Exchange. In
total, this index tracks 500 common stocks.
 
An index may periodically change some of the stocks it tracks. And, different
indexes sometimes track some of the same stocks. For example, as of May 31,
1998, this Index was tracking 18 of the same stocks tracked by the Russell 2000
Index.
 
THE MID CAP INDEX FUND TRACKS THE STANDARD & POOR'S MID CAP 400(R) INDEX*
 
The Standard & Poor's Mid Cap 400(R) Index (S&P Mid Cap 400) tracks the common
stock performance of 400 medium capitalized U.S. and foreign manufacturing,
utilities, transportation, and financial companies as well as companies in other
industries. The average market capitalization of the S&P Mid Cap 400 Index was
$3.4 billion as of December 31, 1997.
 
Standard & Poor's created this Index in 1991 to give investors an idea of how
the stocks of medium capitalized companies generally perform.
 
Standard & Poor's may periodically change some of the stocks in the index. And,
different indexes sometimes include some of the same stocks. For example, as of
May 31, 1998, this Index was tracking 130 of the same stocks tracked by the
Russell 2000 Index. This Index does not track the same stocks as the S&P 500
Index.
 
THE SMALL CAP INDEX FUND TRACKS
THE RUSSELL 2000(R) INDEX**
 
The Russell 2000(R) Index is provided by The Frank Russell Company. This Index
tracks the common stock performance of 2,000 small capitalized U.S. companies in
various industries. Small capitalized means these companies have a market value
below $1 billion.
 
The Frank Russell Company created this Index in 1979 to give investors an idea
of how the stocks of small capitalized companies generally perform. The average
market capitalization of the Russell 2000 Index is $820 million as of December
31, 1997.
 
The stocks tracked by this Index are updated annually because many small
capitalized companies eventually become medium capitalized companies and some
 
fail.

INDEX FUNDS have out- performed
most actively managed mutual
funds over consecutive ten year
periods. However, because they
are managed to track an index
they will rise and fall with
the market.

- --------------------------------------------------------------------------------
 
HOW CLOSELY CAN INDEX FUNDS TRACK THE PERFORMANCE OF THEIR INDEX?
 
The factors that cause a Fund to perform differently from the Index it tries to
track are called tracking differences. There is no assurance that an Index Fund
can track its index.
 
The coefficient of correlation (r) is an index number which shows how closely
two variables are related. If r = 0 there is no tendency for one variable to
change with the other. A value of +1 means that one variable will vary exactly
with the other. Index funds try to keep their coefficient of correlation as
close to 1 as possible. As a practical matter, any coefficient above 0.95, when
measured against the comparison index, shows good tracking.
 
The index may remove one stock and substitute another requiring the sub-adviser
of the Fund to do the same. When a stock is sold and the new stock purchased,
the Fund incurs transaction costs. The index incurs no transaction costs.
Therefore, the portfolio manager cannot match exactly the performance of an
index.
 
Also, it may not be possible for a Fund to buy every stock in its index or in
the same proportions. Fund portfolio managers may rely on a statistical
selection technique to figure out, of the stocks tracked by their index, how
many and which ones to buy. Stocks are bought and sold when they are added to or
dropped from the Index. This keeps brokerage fees and other transaction costs
low. For more information, see the "Investment Strategy" sections on each Fund's
Fact Sheet.

PERFORMANCE INFORMATION
 
This shows the average annual total return for a mutual fund, a managed account
or a composite of mutual funds and/or managed accounts, managed in substantially
the same manner and by the same individuals as those employed by VALIC or a
Sub-adviser to manage a Fund, for the time period indicated. [Information about
how the mutual fund, managed account or composite performed last year is
discussed.] The graph also shows the return for an index to which we compare the
mutual fund's, the managed account's or the composite's performance. For all the
Funds except the three Index Funds, the Small Cap Value Fund and the three
Lifestyle Funds we call this the Fund's "benchmark". The difference between the
Fund and index return is caused by Fund expenses and tracking differences.

PORTFOLIO MANAGER
 
Frank Salerno, Managing Director-Chief Investment Officer of Quantitative and
Index Equity of the Sub-adviser, has been the Fund's portfolio manager since its
inception. Mr. Salerno has been with the Sub-adviser since 1981.
 
INVESTMENT OBJECTIVE
Seeks to provide investment results that, before Expenses, correspond to the
total return (i.e., the combination of capital changes and income) of common
stocks publicly traded in the United States, as represented by the S&P 500 Index
(Index).
INVESTMENT RISK
The S&P 500 Index includes the stock of many large, well-established companies.
These companies usually have the financial strength to weather difficult
financial times. However, the value of any stock can rise and fall over short
and long periods of time. This Fund, which holds nearly all of the 500 stocks in
the S&P 500 Index, avoids the risk of individual stock selection and seeks to
provide the return of the large company sector of the market. In the past that
return has been positive over many years but can be negative at certain times.
There is no assurance that a positive return will occur in the future.
 
Because the Fund invests in many of the stocks tracked by this Index, your
investment will experience similar changes in value and share similar risks,
such as market risk and risk associated with foreign securities. For more
information about market risk and risk associated with foreign securities, see
"A Word About Risk" in this prospectus.
 
INVESTMENT STRATEGY
 
The Fund invests in a sampling of stocks in the Index that, as a group, should
reflect its performance. The stocks of the S&P 500 Index to be included in the
Fund will be selected utilizing a statistical sampling technique known as
"optimization." This process selects stocks for the Fund so that various
industry weightings, market capitalizations and fundamental characteristics
(e.g., price-to-book, price-to-earnings, debt-to-asset ratios and dividend
yields) closely approximate those of the S&P 500 Index. The stocks held by the
Fund are weighted to make the Fund's aggregate investment characteristics
similar to those of the Index as a whole. Since it may not be possible for this
Fund to buy every stock included on this Index or in the same proportions, we
rely on the aforementioned statistical technique to figure out, of the stocks
tracked by the Index, how many and which ones to buy.
 
We follow the guidelines listed below for making the primary investments for the
Fund.

INVESTMENT SUB-ADVISER
 
Bankers Trust Company
 
PORTFOLIO MANAGER
 
Frank Salerno, Managing Director-Chief Investment Officer of Quantitative and
Index Equity of the Sub-adviser, has been the Fund's portfolio manager since its
inception. Mr. Salerno has been with the Sub-adviser since 1981.
 
INVESTMENT OBJECTIVE
 
Seeks to provide growth of capital through investments primarily in a
diversified portfolio of common stocks that, as a group, are expected to provide
investment results closely corresponding to the performance of the S&P Mid Cap
400 Index (Index).
 
INVESTMENT RISK
 
The S&P Mid Cap 400 Index includes the stocks of many medium sized companies.
These companies usually do not have as much financial strength as very large
companies and so may not be able to do as well in difficult times. However,
because they are medium sized, they have more potential to grow, which means the
value of their stock may increase. The S&P Mid Cap 400 Index also includes
stocks of certain medium sized foreign companies. These stocks can be more risky
than large company stocks. An index fund holding nearly all of the 400 stocks in
the S&P Mid Cap 400 Index avoids the risk of individual stock selection and
seeks to provide the return of the medium-sized company sector of the market. On
average that return has been positive over many years but can be negative at
certain times. There is no assurance that a positive return will occur in the
future.
 
Because this Fund invests in many of the stocks tracked by this Index, your
investment will experience similar changes in value and share similar risks such
as market risk and risk associated with foreign securities. For more information
about market risk and risk associated with foreign securities, see "A Word About
Risk" in this prospectus.
 
INVESTMENT STRATEGY
 
The Fund invests in a sampling of stocks in the Index that, as a group, should
reflect its performance. The stocks of the S&P Mid Cap 400 Index to be included
in the Fund will be selected utilizing a statistical sampling technique known as
"optimization." This process selects stocks for the Fund so that various
industry weightings, market capitalizations and fundamental characteristics
(e.g. price-to-book, price-to-earnings, debt-to-asset ratios and dividend
yields) closely approximate those of the S&P Mid Cap 400 Index. The stocks held
by the Fund are weighted to make the Fund's aggregate investment characteristics
similar to those of the Index as a whole. Since it may not be possible for this
Fund to buy every stock included on this index or in the same proportions, we
rely on the aforementioned statistical technique to figure out, of the stocks
tracked by the index, how many and which ones to buy.
 
We follow the guidelines listed below for making the primary investments for the
Fund.

PORTFOLIO MANAGER
 
Frank Salerno, Managing Director-Chief Investment Officer of Quantitative and
Index Equity of the Sub-adviser, has been the Fund's portfolio manager since its
inception. Mr. Salerno has been with the Sub-adviser since 1981.
 
INVESTMENT OBJECTIVE
 
Seeks to replicate as closely as possible (before deduction of Expenses) the
total return of the Russell 2000 Index (Index) by investing in one or more
companies included in the Index that are deemed representative of the
diversification of the entire Russell 2000 Index.
 
INVESTMENT RISK
 
The Russell 2000 Index includes many small U.S. companies. Some of these
companies often do not have the financial strength needed to do well in
difficult times. Also, they often sell limited numbers of products, which can
make it harder for them to compete with medium and large companies. However,
because they are small, their stock prices may fluctuate more over the
short-term, but they have more potential to grow. This means their stock value
may offer greater potential for appreciation. An index fund holding a large
sampling of the 2,000 stocks in the Russell 2000 Index avoids the risks of
individual stock selection and seeks to provide the return of the smaller-sized
company sector of the market. On average that return has been positive over the
years but has been negative at certain times. There is no assurance that a
positive return will occur in the future.
 
Because this Fund invests in many of the stocks tracked by this Index, your
investment will experience similar changes in value and share similar risks such
as market risk. For more information about market risk, see "A Word About Risk"
in this prospectus.

PORTFOLIO MANAGER
 
This Fund is managed by an investment committee comprised of the following
individuals: Daniel L. Jacobs, Wai W. Chin and Robert J. Jurgens. Mr. Jacobs has
been President of the Sub-adviser since July 1, 1995. From 1984 to 1995, Mr.
Jacobs was Executive Vice President and Director of Templeton Investment
Counsel. Mr. Jacobs was portfolio manager of Templeton's Smaller Companies
Growth Fund. Ms. Chin has been Managing Director of Asian Research and Portfolio
Management of the Sub-adviser since July 1995. Prior to this, Ms. Chin was Vice
President of the Global Equity Group of Scudder, Stevens & Clark. Mr. Jurgens
has been Managing Director of European Research and Portfolio Management of the
Sub-adviser since August 1995. From 1993 to 1995, Mr. Jurgens was Vice President
and head of AIG Global Investors' International Equity Division.
 
INVESTMENT OBJECTIVE
 
Seeks to provide long-term capital appreciation by investing in equity
securities of companies in developed and emerging markets. The Fund may invest
across the capitalization spectrum, although it intends to emphasize smaller
capitalization stocks.
 
INVESTMENT RISK
 
As described in the Investment Strategy section below, this Fund invests almost
all its assets in foreign securities, which have risks that U.S. investments do
not have. For a further explanation of the risks associated with foreign
securities, see "A Word About Risk" in this prospectus.
 
INVESTMENT STRATEGY
 
The Fund will invest in equity securities in the markets of at least three
countries outside the United States. The Fund will focus its investments on
developed and emerging market countries. Emerging market country investments
will be made only where we believe the economies are developing and the markets
are becoming more sophisticated.
 
We will use a flexible, value-oriented approach to selecting this Fund's
investments, focusing on companies rather than on countries or markets. Our goal
is to identify stocks selling at the greatest discount to their intrinsic future
value. Value is ascertained through an analysis of price/cash flow, enterprise
value/cash flow, and price/future earnings. This Fund invests in a wide range of
stocks including smaller capitalization companies.
 
We follow the guidelines listed below for making the primary investments for the
Fund.

PORTFOLIO MANAGER
 
This Fund is managed by the following individuals: Kent Clark; Robert L. Jones;
and Victor H. Pinter. Mr. Jones, Managing Director, joined the Sub-adviser in
1989. Mr. Clark has been Vice President of the Sub-adviser since 1992. Mr.
Pinter has been Vice President of the Sub-adviser since 1990.
 
INVESTMENT OBJECTIVE
 
Seeks long-term growth of capital through a broadly diversified portfolio of
equity securities of large cap U.S. issuers that are expected to have better
prospects for earnings growth than the growth rate of the general domestic
economy. Dividend income is a secondary consideration.
 
INVESTMENT RISK
 
This Fund invests almost entirely in stocks. Stock values can rise and fall over
both short and long periods of time. The Fund's investments are selected to
maintain a risk profile similar to the Russell 1000 Growth Index, and your
investment may experience similar changes in value and share similar risks such
as market risk, credit risk, interest rate risk and risk associated with foreign
securities. For more information about market risk, credit risk, interest rate
risk and risk associated with foreign securities, see "A Word About Risk" in
this prospectus.
INVESTMENT STRATEGY
The Fund will be managed utilizing Goldman Sachs' Quantitative Equity Strategy.
The acronym "CORE" (Computer-Optimized and Research Enhanced) reflects the three
step investment process the team uses to select securities. First, we estimate
the returns of 3000 U.S. stocks using a combination of research from the Goldman
Sachs Global Investment Research Department, other industry sources and
objective quantitative analysis. Next, the Fund's investment portfolio is
constructed by balancing expected returns against portfolio risk, trading fees
and investment objectives. The Fund is intended to be constructed with minimum
deviations from the sector, risk statistics and macroeconomic sensitivity of the
benchmark. A proprietary multi-factor model is used in seeking to ensure risks
taken are both intended and are warranted due to expected return. Lastly, the
Fund is traded regularly and rebalanced in seeking to ensure all positions are
in line with current market outlooks and benchmark weights.
 
We follow the guidelines listed below for making the primary investments for
this Fund.

LARGE CAP GROWTH FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Large Cap Growth Fund has not commenced operations and has no investment
performance record. However, the Fund will be managed in substantially the same
manner and by the same individuals as those employed by the Sub-adviser for the
Goldman Sachs CORE Large Cap Growth Fund. The chart below shows the historical
investment performance for the Goldman Sachs CORE Large Cap Growth Fund for the
period from May 1, 1997 to present. Performance information prior to May 1, 1997
(commencement date for Goldman Sachs CORE Large Cap Growth Fund) is that of a
predecessor separate account adjusted to reflect the higher fees and expenses
applicable to Goldman Sachs CORE Large Cap Growth Fund. The performance
information below for the Large Cap Growth Fund is a composite of the Goldman
Sachs CORE Large Cap Growth Fund and a predecessor separate account
("Composite"). Although the predecessor separate account was managed by GSAM in
substantially the same manner and by the same individuals as the Goldman Sachs
CORE Large Cap Growth Fund, the separate account was not registered under the
1940 Act and was not subject to certain investment restrictions imposed by the
1940 Act. If it had been registered under the 1940 Act, performance might have
been adversely affected.
 
Fees and expenses of the Large Cap Growth Fund may differ from the fees and
expenses historically incurred by the Composite. The performance figures have
been adjusted to reflect an additional deduction of [    %] for the Large Cap
Growth Fund. This deduction represents an estimate of the maximum fee
differential between the two funds. The fee differential from the inception date
of the Composite to the present could have been greater or lesser in any given
year. See "Performance Information" for an explanation of the information
presented below. THE PERFORMANCE INFORMATION BELOW IS BASED ON A FUND COMPARABLE
TO THE LARGE CAP GROWTH FUND AND DOES NOT REFLECT THE PERFORMANCE OF THE FUND
ITSELF.

PORTFOLIO MANAGER
The Fund is managed by a team led by Eddie C. Brown. Mr. Brown is Founder,
President and controlling shareholder of the Sub-adviser. Mr. Brown has been
with the Sub-adviser since its inception in 1983.
 
INVESTMENT OBJECTIVE
 
Seeks capital appreciation principally through investments in equity securities,
such as common and preferred stocks and securities convertible into common
stocks. Current income is of secondary importance.
 
INVESTMENT RISK
 
This Fund invests mostly in stocks of medium sized companies that we believe are
undervalued in the marketplace. The value of any stock may rise or fall over
long or short periods of time. Although these stocks present an opportunity for
capital appreciation, they may not be broadly traded and involve market risk and
risk associated with foreign securities. For a discussion of market risk and
risk associated with foreign securities, see "A Word About Risk" in this
prospectus.
 
INVESTMENT STRATEGY
 
This Fund will invest principally in the equity securities of medium
capitalization companies. We will seek to achieve capital appreciation through
an opportunistic stock investment strategy with a growth bias. This Fund will
purchase equity securities of those companies that we feel are undervalued
relative to their growth potential in the securities markets, because the
companies are presently out of favor, not well known or possess value that is
not currently recognized by the investment community. We use a "bottom up"
approach to select specific securities, employing analysis that contains
elements of traditional dividend discount and earnings yield models, establishes
predicted relative valuation for equity and fixed income markets, and determines
the attractiveness of individual securities through evaluation of growth and
risk characteristics of the underlying company relative to the overall equity
market. Although the Fund's portfolio securities generally will be acquired for
the long term, they may be sold under some of the following circumstances when
the Sub-adviser believes that: a) the anticipated price appreciation has been
achieved or is no longer probable; b) alternative investments offer superior
total return prospects; or c) fundamentals change adversely.
 
We follow the guidelines listed below for making the primary investments for
this Fund.

the Fund's strategies will be substantially similar to those employed by the
Sub-adviser with respect to certain discretionary investment management accounts
under their management ("Combined Accounts"). The chart below shows the
historical investment performance for a composite of these Combined Accounts)
("Combined Accounts Composite"). The Combined Accounts Composite includes all
discretionary accounts managed by the Sub-adviser invested principally in equity
securities of medium capitalization companies using the same investment strategy
that the Sub-adviser will employ on behalf of the Fund. The inception date for
the Combined Accounts Composite was August 31, 1992.
 
The discretionary accounts in the Combined Accounts Composite are not subject to
the investment limitations, diversification requirements and other restrictions
imposed on registered mutual funds by the 1940 Act and the Internal Revenue
Code. If the accounts included in the Combined Accounts Composite had been
subject to the requirements imposed on mutual funds, their performance might
have been lower.

Candice Eggerss and Saira Malik are the members of the Sub-adviser's team who
will be primarily responsible for the day-to-day management of the Fund. Ms.
Eggerss, who has been with the Sub-adviser since 1996, is Vice President and
specializes in portfolio investments in small capitalization technology
companies. Prior to this, Ms. Eggerss was employed at Weiss, Peck and Greer from
April 1993 to April 1996 and at Equitable Capital Management prior to 1993. Ms.
Malik joined the Sub-adviser in 1995 after completing her graduate studies at
the University of Wisconsin.
INVESTMENT OBJECTIVE
 
Seeks to provide long-term growth from a portfolio of small company growth
stocks.
INVESTMENT RISK
 
This Fund invests primarily in U.S. small company growth stocks. These companies
may not have the financial strength to do well in difficult times. Because they
are small, the stock prices of these companies may fluctuate more over the short
term but they have more potential to grow. This means their stock value may
offer greater potential for appreciation. The securities that the Fund invests
in involve certain risks such as market risks and risk associated with foreign
securities. For a discussion of these risks, see "A Word About Risk" in this
prospectus.
 
INVESTMENT STRATEGY
 
This Fund invests in U.S. companies whose market capitalizations are greater
than $150 million and less than $1.25 billion. On an industry by industry basis,
the Fund's weightings are similar to those of the Russell 2000 Growth Index.
Within each industry, the Fund invests in the stocks that our research and
valuation process indicate are the most undervalued. The greater a company's
estimated worth compared to the current market price of its stock, the more
undervalued the company.
 
We follow the guidelines listed below for making the primary investments for the
Fund.

SMALL CAP GROWTH FUND

The Small Cap Growth Fund has not commenced operations and has no investment
performance record. However, the Fund's investment objective and policies and
the Fund's strategies will be substantially similar to those employed by the
Sub-adviser and its affiliates with respect to certain discretionary investment
management accounts under their management ("Combined Accounts"). The chart
below shows the historical investment performance for a composite of these
Combined Accounts ("Combined Accounts Composite"). The Combined Accounts
Composite includes all non-mutual fund discretionary accounts managed by the
Sub-adviser and its affiliates invested solely in the equity securities of small
capitalization companies using the same investment strategy that the Sub-adviser
will employ on behalf of the Fund. The inception date for the Combined Accounts

This Fund is managed using a system of multiple portfolio managers. Under this
system, the Fund is divided into segments, which are assigned to individual
managers.
INVESTMENT OBJECTIVE
 
Seeks to provide growth of capital and future income through investments
primarily in securities of non-U.S. issuers and securities whose principal
markets are outside of the United States.
 
INVESTMENT RISK
 
As described in the Investment Strategy section below, this Fund invests almost
all of its assets in foreign securities, which have risks that U.S. investments
do not have. For a further explanation of the risks associated with foreign
securities and market risk, see "A Word About Risk" in this prospectus.
 
INVESTMENT STRATEGY
 
The Fund invests in a portfolio consisting primarily of common stocks (or
securities convertible into common stocks) and bonds of non-U.S. issuers.
 
While the assets of the Fund can be invested with geographical flexibility, the
emphasis will be on securities of companies located in Europe, Canada,
Australia, and the Far East, giving due consideration to economic, social, and
political developments, currency risks and the liquidity of various national
markets.

INTERNATIONAL VALUE FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The International Value Fund has not commenced operations and has no investment
performance record. However, the Fund's investment objectives, policies and
strategies will be substantially similar to those employed by the Sub-adviser
with respect to certain discretionary investment accounts managed by the
Sub-adviser. The chart below shows the historical investment performance (with
the adjustments noted below) for a composite of the Sub-adviser's similar
accounts which use the same investment strategy that the Sub-adviser will employ
on behalf of the Fund ("Sub-adviser Composite"). The Sub-adviser Composite
represents the total return, gross of management fees, of all relevant accounts
managed on a discretionary basis by the institutional investment management
division of the Sub-adviser. The inception date of the Sub-Adviser Composite was
               .
 
The discretionary accounts in the Sub-adviser Composite are not subject to the
investment limitations, diversification requirements and other restrictions
imposed on registered mutual funds by the 1940 Act and the Internal Revenue
Code. If the accounts included in the Sub-Adviser Composite had been subject to
the requirements imposed on mutual funds, their performance might have been
lower.
 
Fees and expenses of the International Value Fund may differ from the fees and
expenses historically incurred by the accounts within the Sub-Adviser Composite.
The actual Sub-adviser Composite results have been adjusted downward by VALIC to
reflect an additional deduction of [    %] for the International Value Fund.
This deduction represents an estimate of the maximum fee differential between
the International Value Fund and the Sub-adviser Composite. The fee differential

been greater or lesser in any given year. See "Performance Information" for an

PORTFOLIO MANAGER
 
This Fund is managed using a system of multiple portfolio managers.
INVESTMENT OBJECTIVE
Seeks to provide total returns that exceed over time the Russell 1000 Value
Index (Index) through investment in equity securities.
 
INVESTMENT RISK
 
This Fund invests primarily in the stocks of large, well-established companies
that generally possess the strength to withstand difficult financial periods.
Nevertheless, the value of any stock can rise or fall over short and long
periods of time. As described below, in order to avoid unintended exposures to
economic factors, including the direction of the economy, interest rates, energy
prices and inflation, we maintain the proportion of stocks from different
economic sectors in this Fund's portfolio at a level similar to that of the
Russell 1000 Value Index. There is no assurance that the Fund will be unaffected
by such economic factors.
 
Because the Fund maintains sector weights at a similar level to that of the
Index, your investment may experience similar changes in value and share similar
risks such as market risk and risk associated with foreign securities. For more
information about market risk and risk associated with foreign securities, see
"A Word About Risk" in this prospectus.
 
INVESTMENT STRATEGY
 
The Fund will invest primarily in equity securities. Equity securities will be
selected by the Fund and ranked according to two separate and uncorrelated
measures: value and the momentum of Wall Street sentiment. The value measure
compares a company's assets, projected earnings growth and cash flow growth with
its stock price within the context of its historical valuation. The measure of
Wall Street sentiment examines changes in Wall Street analysts' earnings
estimates and ranks stocks by the strength and consistency of those changes.
These two measures will be combined to create a single composite score of each
stock's attractiveness. These scores are used to determine their relative
attractiveness. Sector weights are maintained at a similar level to that of the
Russell 1000 Value Index to avoid unintended exposure to factors such as the
direction of the economy, interest rates, energy prices and inflation.
 
We follow the guidelines listed below for making the primary investments for the
Fund.

LARGE CAP VALUE FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Large Cap Value Fund has not commenced operations and has no investment
performance record. However, the Fund will be managed in substantially the same
manner and by the same individuals as those employed by the Sub-adviser for a
discretionary account (the "Discretionary Account") managed by the Sub-adviser
with similar investment objectives. The Discretionary Account is not subject to
the investment limitations, diversification and other restrictions imposed on
registered mutual funds by the 1940 Act and the Internal Revenue Code. The chart
below shows the historical investment performance for the SSgA Large Cap Value
Fund. The inception date for the Discretionary Account was August, 1992.
 
Fees and expenses of the Large Cap Value Fund will be substantially greater than
the fees and expenses historically incurred by the Discretionary Account. The
performance figures have been adjusted to reflect an additional deduction of
[    %] for the Large Cap Value Fund. This deduction represents an estimate of
the maximum fee differential between the Large Cap Value Fund and the
Discretionary Account. The fee differential from the inception date of the
Discretionary Account to the present could have been greater or lesser in any

PORTFOLIO MANAGER
Michael M. Kassen and Robert I. Gendelman serve as co-managers of the Fund. Mr.

INVESTMENT OBJECTIVE
 
Seeks capital growth, through investment in common stocks of medium- to
large-capitalization established companies using a value-oriented investment
approach.
 
INVESTMENT RISK
 
As described in the Investment Strategy section below, this Fund invests almost
all its assets in stocks of companies that are undervalued in the marketplace.
The value of any stock may rise or fall over long or short periods of time.
Although these stocks present an opportunity for capital appreciation, they may
not be broadly traded and involve market risk and risk associated with foreign
securities. For a discussion of these risks, see "A Word About Risk" in this
prospectus.
 
INVESTMENT STRATEGY
 
This Fund invests principally in common stocks of medium- to
large-capitalization established companies, using a value-oriented investment
approach intended to increase capital with reasonable risk. We choose securities
we believe are undervalued based on strong fundamentals, including a low
price-to-earnings ratio, consistent cash flow, and the company's track record
through all parts of the market cycle. When selecting securities for this Fund,
we also consider other factors as including ownership by a company's management
of the company's stock and the dominance a company in its particular field.
 
We follow the guidelines listed below for making the investments for this Fund.

MID CAP VALUE FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Mid Cap Value Fund has not commenced operations and has no investment
performance record. However, the Fund will be managed in substantially the same
manner and by the same individuals as those employed by the Sub-adviser for the
Neuberger & Berman Partners Fund. The chart below shows the historical
investment performance for the Neuberger & Berman Partners Fund. The inception
date for the Neuberger & Berman Partners Fund was            , 199 .
 
Fees and expenses of the Mid Cap Value Fund may differ from the fees and
expenses historically incurred by the Neuberger & Berman Partners Fund. The
performance figures have been adjusted to reflect an additional deduction of
[    %] for the Mid Cap Value Fund. This deduction represents an estimate of the
maximum fee differential between the two funds. The fee differential from the
inception date of the Neuberger & Berman Partners Fund to the present could have
been greater or lesser in any given year. See "Performance Information" for an
explanation of the information presented below. THE PERFORMANCE INFORMATION

PORTFOLIO MANAGER
 
Patricia A. Falkowski, President and Chief Investment Officer of FMA has been
Portfolio Manager for the actively-managed portion of the Fund's portfolio since
the Fund's inception. Ms. Falkowski has been with FMA since 1991.
 
Frank Salerno, Managing Director-Chief Investment Officer of Quantitative and
Equity Index of Bankers Trust, has been the portfolio manager for the
passively-managed portion of this Fund's portfolio since the Fund's inception.
Mr. Salerno has been with Bankers Trust since 1981.
 
INVESTMENT OBJECTIVE
 
Seeks maximum long-term return, consistent with reasonable risk to principal, by
investing primarily in common stocks of smaller companies in terms of revenues
and/or market capitalization.
 
INVESTMENT RISK
 
As described below, this Fund invests in smaller capitalization companies. Some
of these companies do not have the financial strength to do well in difficult
times.
 
A portion of this Fund's portfolio is invested in a statistically-selected
sampling of the 2000 stocks in the Russell 2000 Index. This part of the Fund's
investment portfolio avoids the risks of individual stock selection and seeks to
achieve and exceed the return of the smaller-sized company sector of the market.
On the average, that return has been positive, but has been negative at certain
times. There is no assurance that a positive return will occur in the future.
 
Because this Fund invests in smaller capitalization stocks, your investment may
exhibit greater market value volatility than investments in common stocks of
larger companies. Your investment also will experience similar changes in value
and share similar risks as stocks included in the Russell 2000 Index, such as
market risk and risk associated with investment in foreign securities. For more
information about these risks, see "A Word About Risk" in this prospectus.
 
INVESTMENT STRATEGIES
 
This Fund invests primarily in common stocks of small capitalization companies.
One portion of the Fund's investment portfolio will be actively managed and the
other portion will be passively managed. In analyzing and selecting investments
for the actively-managed portion of the Fund's investment portfolio, we look for
market themes and changes that signal opportunity. We seek companies with lower
price-to-earnings ratios, strong cash flow, good credit lines and clean or
improving balance sheets. At any given time, this portion of the Fund's
investment portfolio will be invested in a diversified group of small
capitalization stocks in several industries. The Fund will invest primarily in
U.S. companies with seasoned management or a track record as part of a larger
company.
 
The passively-managed portion of the Fund's investment portfolio is comprised of
a sampling of stocks in the Russell 2000 Index that, as a group, should reflect
its performance. The stocks of the Russell 2000 Value Index to be included in
the Fund will be selected utilizing a statistical sampling technique known as
"optimization." This process selects stocks for the Fund so that various
industry weightings, market capitalizations and fundamental characteristics
(e.g. price-to-book, price-to-earnings, debt-to-asset ratios and dividend
yields) closely approximate those of the Russell 2000 Value Index. The stocks
held by the Fund are weighted to make the Fund's aggregate investment
characteristics similar to those of the Index as a whole. Since it may not be
possible for this Fund to buy every stock included on this index or in the same
proportions, we rely on the aforementioned statistical technique to figure out,
of the stocks tracked by the index, how many and which ones to buy.

PORTFOLIO MANAGER
 
John W. Mossbarger has been this Fund's portfolio manager and Vice President and
Investment Officer of the Series Company since its inception. Since 1992, Mr.
Mossbarger has served as Vice President and Investment Officer of American
General Series Portfolio Company, a registered, open-end investment company.
 
INVESTMENT OBJECTIVE
 
Seeks to obtain growth of capital through investment, primarily in common
stocks, in companies which meet the social criteria established for the Fund.
The Fund invests only in companies which meet its social criteria. The Fund does
not invest in companies that:
 
  - produce nuclear energy;
 
  - make military weapons or delivery systems; or
 
  - engage continuously in practices or produce products that significantly
    pollute the environment (such products include tobacco products).
 
INVESTMENT RISK
Most of the companies this Fund invests in are included in the S&P 500 Index.
This Fund's degree of market risk is slightly greater than the S&P 500 Index
Fund's degree of risk. This is because its investments are more limited by its
investment objective. This Fund may also experience market risk, and risks
associated with foreign securities. For a discussion of these risks see the S&P
500 Index Fund's Fact Sheet and "A Word About Risk" in this prospectus.
If a company stops meeting the Fund's social criteria after the Fund invested in
it, the Fund will sell these investments even if this means the Fund loses
money. Also, if the Fund changes its social criteria and the companies the Fund
has already invested in no longer qualify, the Fund will sell these investments
even if this means the Fund loses money. Social criteria screening will limit
the availability of investment opportunities for the Fund more than for funds
having no such criteria.
 
To find out which companies meet the Fund's social criteria, we rely on industry
classifications, research services such as the Investor Responsibility Research
Center (IRRC), and special magazines and papers that publish this type of
information.
 
Since our definition of social criteria is not "fundamental," the Series
Company's Board of Trustees may change it without shareholder approval. When
deciding to make changes to the criteria, the Board will consider, among other
things, new or revised state laws that govern or affect the investments of
public funds. At least once a year, we survey state laws on this issue to look
for any new developments. If our survey shows that at least 20 states have
adopted laws that restrict public funds from being invested in a clearly
definable category of investments, this category is automatically added to our
social criteria list.
 
INVESTMENT STRATEGY
 
We follow the guidelines listed below for making the primary investments for the
Fund.

PORTFOLIO MANAGER
 
This Fund is managed using a system of multiple portfolio managers. Under this
system, the Fund is divided into segments, which are assigned to individual
managers.
 
INVESTMENT OBJECTIVE
 
Seeks balanced accomplishment of
(i) conservation of principal and (ii) long-term growth of capital and income
through investment in fixed income and equity securities.
 
INVESTMENT RISK
 
This Fund invests principally in debt securities and stocks. Stock values can
rise and fall over long and short periods of time and involve market risks. Like
equity securities, debt securities involve certain risks, including interest
rate risk, credit risk, market risk and risk associated with foreign securities.
This may cause the debt securities that the Fund owns to be worth less than the
Fund paid. For a discussion of these risk, see "A Word About Risk" in this
prospectus.
 
INVESTMENT STRATEGY
 
The Fund invests in a combination of debt securities and stock in order to
maintain the value of your principal investment and provide you with capital
growth and income over the long-term. We select securities for the Fund's
portfolio by identifying the stock and debt that represent fundamental values at
reasonable prices. We implement this philosophy using a system of portfolio
managers, under which a different portfolio manager makes investment decisions
for the debt and equity portions of the Fund.
 
We follow the guidelines listed below for making the primary investments for the
Fund.

BALANCED FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Balanced Fund has not commenced operations and has no investment performance
record. However, the Fund's investment objectives, policies and strategies will
be substantially similar to those employed by the Sub-adviser with respect to
certain discretionary investment accounts managed by the Sub-adviser. The chart
below shows the historical investment performance (with the adjustments noted
below) for a composite of the Sub-adviser's similar accounts which use the same
investment strategy that the Sub-adviser will employ on behalf of the Fund
("Sub-adviser Composite"). The Sub-adviser Composite represents the total
return, gross of management fees, of all relevant accounts managed on a
discretionary basis by the institutional investment management division of the
Sub-adviser. The inception date of the Sub-adviser Composite was               .
 
The discretionary accounts in the Sub-adviser Composite are not subject to the
investment limitations, diversification requirements and other restrictions
imposed on registered mutual funds by the 1940 Act and the Internal Revenue
Code. If the accounts included in the Sub-adviser Composite had been subject to
the requirements imposed on mutual funds, their performance might have been
lower.
 
Fees and expenses of the Balanced Fund may differ from the fees and expenses
historically incurred by the accounts within the Sub-adviser Composite. The
actual Sub-adviser Composite results have been adjusted downward by VALIC to
reflect an additional deduction of [    %] for the Balanced Fund. This deduction
represents an estimate of the maximum fee differential between the Balanced Fund
and the Sub-adviser Composite. The fee differential from the inception date of
the Sub-adviser Composite to the present could have been greater or lesser in
any given year. See "Performance Information" for an explanation of the

Baker, Vice President and fixed-income portfolio manager of an affiliate of the
Sub-adviser, has focused on the application of quantitative valuations to
investment grade bonds and portfolios for the Sub-adviser since 1987. Mr.
Mulally, Senior Vice President, Director and Chairman of the Sub-adviser's Fixed
Income Subcommittee, joined the Sub-adviser in 1980.
 
INVESTMENT OBJECTIVE
Seeks the highest possible total return consistent with conservation of capital
through investment in debt instruments and other income producing securities.
 
INVESTMENT RISK
 
The securities the Fund invests in involve certain risks, such as interest rate
risk, credit risk, market risk and risk associated with foreign securities. This
may cause the debt instruments that the Fund owns to be worth less than what the
Fund paid. For a discussion of these risks see "A Word About Risk" in this
prospectus.
 
INVESTMENT STRATEGY
 
The Fund invests in high quality bonds to provide you with the highest possible
total return from current income and capital gains while preserving your
investment. To increase the Fund's earning potential, we may use a small part of
the Fund's assets to make some higher risk investments.

The Domestic Bond Fund has not commenced operations and has no investment
performance record. However, the Fund's investment objectives, policies and
strategies will be substantially similar to those employed by the Sub-adviser
with respect to certain discretionary investment accounts managed by the
Sub-adviser. The chart below shows the historical investment performance (with
the adjustments noted below) for a composite of the Sub-adviser's similar
accounts which use the same investment strategy that the Sub-adviser will employ
on behalf of the Fund ("Sub-adviser Composite"). The Sub-adviser Composite
represents the total return, gross of management fees, of all relevant accounts
managed on a discretionary basis by the institutional investment management
division of the Sub-adviser. The inception date of the Sub-adviser Composite was
              .
 
The discretionary accounts in the Sub-adviser Composite are not subject to the
investment limitations, diversification requirements and other restrictions
imposed on registered mutual funds by the 1940 Act and the Internal Revenue
Code. If the accounts included in the Sub-adviser Composite had been subject to
the requirements imposed on mutual funds, their performance might have been
lower.
 
Fees and expenses of the Domestic Bond Fund may differ from the fees and
expenses historically incurred by the accounts within the Sub-adviser Composite.
The actual Sub-adviser Composite results have been adjusted downward by VALIC to
reflect an additional deduction of [    %] for the Domestic Bond Fund. This
deduction represents an estimate of the maximum fee differential between the
Domestic Bond Fund and the Sub-adviser Composite. The fee differential from the
inception date of the Sub-adviser Composite to the present could have been
greater or lesser in any given year. See "Performance Information" for an
explanation of the information presented below. THE PERFORMANCE INFORMATION
BELOW IS BASED ON A COMPOSITE COMPARABLE TO THE FUND AND DOES NOT REFLECT THE
PERFORMANCE OF THE FUND ITSELF.

PORTFOLIO MANAGER
 
Teresa Moro has been this Fund's portfolio manager and Vice President and
Investment Officer of the Series Company since its inception. Since 1991, Ms.
Moro has served as Vice President and Investment Officer of American General
Series Portfolio Company, a registered investment company.
 
INVESTMENT OBJECTIVE
 
Seeks liquidity, protection of capital and current income through investments in
short-term money market instruments.
 
INVESTMENT RISK
 
The short-term money market securities that this Fund invests in are high
quality investments, posing low credit and interest rate risk. The current yield
of the Fund will generally go up or down with changes in the level of interest
rates. The Fund uses the amortized cost method to value its portfolio securities
and tries to keep its net asset value at $1.00 per share. There can be no
assurance that the net asset value will be $1.00 per share at all times.
 
Because the risk to the money you invest is low, the potential for profit is
also low. The Fund may experience risks including interest rate risk, market
risk, credit risk and risk associated with foreign securities. For a discussion
of these risks, see "A Word About Risk" in this prospectus.
 
INVESTMENT STRATEGY
 
The Fund invests in short-term money market securities to provide you with
liquidity, protection of your investment and current income. We use 95% of the
Fund's assets to buy short-term securities that are rated within the highest
rating category for short term debt obligations by at least two nationally
recognized rating services or unrated securities of comparable investment
quality. These eligible securities must mature in 13 months or less and the Fund
must have a dollar-weighted average portfolio maturity of 90 days or less. These
practices are designed to minimize any fluctuation in the value of the Fund's
portfolio.
 
The investments this Fund may buy include:
 
  - Securities issued or guaranteed by the U.S. Government, its agencies or
    instrumentalities
 
  - Certificates of deposit and other obligations of domestic banks that have
    total assets in excess of $1 billion
 
  - Commercial paper sold by corporations and finance companies
 
  - Corporate debt obligations with remaining maturities of 13 months or less
 
  - Repurchase agreements
 
  - Money market instruments of foreign issuers payable in U.S. dollars (limited
    to no more than 20% of the Fund's net assets)
 
  - Asset-backed securities
 
  - Loan participations
 
  - Adjustable rate securities
 
  - Illiquid and restricted securities (including Rule 144A Securities)*

TYPES OF INVESTMENTS
- --------------------------------------------------------------------------------
 
STOCKS -- also called equity securities
 
If you own a share of stock, you own a part of the company that issued it.
Companies sell stock to get the money they need to grow.
 
Generally, there are three types of stocks:
 
Common stock -- Each share of common stock represents a part of the ownership of
the company. The holder of common stock participates in the growth of the
company through increasing stock price and receipt of dividends. If the company
runs into difficulty, the stock price can decline and dividends may not be paid.
 
Preferred stock -- Each share of preferred stock allows the holder to get a set
dividend before the common stock shareholders receive any dividends on their
shares.
 
Convertible preferred stock -- A stock with a set dividend which the holder may
exchange for a certain amount of common stock.
 
All of the Funds except the Lifestyle Funds, the Money Market Fund and the
Domestic Bond Fund, may invest in common, preferred, and convertible preferred
stock in accordance with their investment strategies.
 
Stocks are not the only type of equity securities. More information about other
types of equity securities in which certain Funds may invest is contained in the
Statement of Additional Information.
 
BONDS -- also called debt securities
 
Bonds are sold by governments on the local, state, and federal levels, and by
companies. There are many different kinds of bonds. For example, each bond issue
has specific terms. U.S. Government bonds are guaranteed to pay interest and
principal by the federal government. Revenue bonds are usually only paid from
the revenue of the issuer. An example of that would be an airport revenue bond.
Debentures are a very common type of corporate bond (a bond sold by a company).
Payment of interest and return of principal is subject to the company's ability
to pay. Convertible bonds are corporate bonds that can be exchanged for stock.
The types of bonds that most Funds may invest in include, but are not limited
to: U.S. Government bonds and investment grade corporate bonds (the Mid Cap
Value Fund, the Balanced Fund and the Domestic Bond Fund may also invest in
below investment grade bonds). For a description of investment grade bonds see
"A Word about Risk -- Market Risk" in this prospectus.
 
Investing in a bond is like making a loan for a fixed period of time at a fixed
interest rate. During the fixed period, the bond pays interest on a regular
basis. At the end of the fixed period, the bond matures and the investor usually
gets back the principal amount of the bond. Fixed periods to maturity are
categorized as short term (generally less than 12 months), intermediate (one to
10 years), and long term (10 years or more). Commercial paper is a specific type
of corporate or short term note. In fact, it's very short term, being paid in
less than 270 days. Most commercial paper matures in 50 days or less.
 
Bonds rated Ba or B by Moody's and S&P (generally known as lower-medium and
lower-quality bonds) are regarded, on balance, as predominantly speculative with
respect to the issuer's capacity to pay interest and principal in accordance
with the terms of the obligation. While such bonds will likely have some quality
and protective characteristics, these are outweighed by uncertainties or risk
exposures to adverse conditions. Lower-medium and lower-quality bonds may be
more susceptible to real or perceived adverse economic and individual corporate
developments than would investment grade bonds.
 
For example, a projected economic downturn or the possibility of an increase in
interest risk bond prices because such an event might lessen the ability of
highly leveraged high yield issuers to meet their principal and interest payment
obligations, meet projected business goals, or obtain additional financing. In
addition, the secondary trading market for lower-medium and lower-quality bonds
may be less liquid than the market for investment grade bonds. This potential
lack of liquidity may make it more difficult to accurately value certain of
these lower-grade portfolio securities.
 
Asset-Backed Securities
 
Asset-backed securities are bonds or notes that are normally supported by a
specific property. If the issuer fails to pay the interest or return the
principal when the bond matures, then the issuer must give the property to the
bondholders or noteholders. All of the Funds in this prospectus, except the
Lifestyle Funds and the Mid Cap Value Fund, may invest in asset-backed
securities. Examples of assets supporting asset-backed securities include credit
card receivables, retail installment loans, home equity loans, auto loans, and
manufactured housing loans.
 
ISSUED means the
Company (ISSUER) sold it
originally to the public.

Information.

<PAGE>   51
- --------------------------------------------------------------------------------
 
Loan Participations
 
A loan participation is an investment in a loan made to a U.S. company that is
secured by the company's assets. The assets must be, at all times, worth enough
money to cover the balance due on the loan. Major national and regional banks
make loans to companies and then sell the loans to investors. These banks don't
guarantee the companies will pay the principal and interest due on the loans.
 
All the Funds in this prospectus, other than the Lifestyle Funds and the Mid Cap
Value Fund, may invest in loan participations.
 
VARIABLE AMOUNT DEMAND MASTER NOTES
 
The Large Cap Value Fund, the Mid Cap Value Fund, the Balanced Fund and the
Domestic Bond Fund may invest in variable amount demand master notes. Variable
amount master demand notes are unsecured obligations that are redeemable upon
demand and are typically unrated. These instruments are issued pursuant to
written agreements between their issuers and holders. The agreements permit the
holders to increase (subject to an agreed maximum) and the holders and issuers
to decrease the principal amount of the notes, and specify that the rate of
interest payable on the principal fluctuates according to an agreed formula.
 
STRUCTURED SECURITIES
 
The value of the principal of and/or interest on such securities is determined
by reference to changes in the value of specific currencies, interest rates,
commodities, indices or other financial indicators (the "Reference") or the
relative change in two or more References. The interest rate or the principal
amount payable upon maturity or redemption may be increased or decreased
depending upon changes in the applicable Reference. The terms of the structured
securities may provide that in certain circumstances no principal is due at
maturity and, therefore, result in the loss of a Fund's investment.
 
The Balanced Fund and the Domestic Bond Fund may invest in structured
securities.
 
REAL ESTATE SECURITIES
 
All of the Funds in this prospectus, except the Lifestyle Funds and the Domestic
Bond Fund, may invest in real estate securities. Real estate securities are
securities issued by companies that invest in real estate or interests therein.
Certain Funds also may invest in real estate investment trusts ("REITs"). REITs
are generally publicly traded on the national stock exchanges and in the
over-the-counter market and have varying degrees of liquidity. More information
about REITs and real estate securities generally is contained in the Statement
of Additional Information.
 
ILLIQUID AND RESTRICTED SECURITIES
 
An illiquid security is one that may not be frequently traded. If it must be
sold quickly, it may have to be sold at a loss. For example, if a fund owns a
stock that is not sold very often and the fund needs to sell this stock quickly,
it may have to offer the investment at a low price for someone to buy it.
 
A restricted security is one that has not been registered with the SEC and
therefore can't be sold in the public market. Restricted securities do include
securities eligible for resale under Rule 144A of the Securities Act of 1933.
Some Rule 144A securities may be liquid as determined by VALIC or a Sub-adviser.
For more information about Rule 144A securities see the Statement of Additional
Information. These investments can be very risky because the Fund's ability to
sell a restricted stock is very limited.
 
All the Funds, except the Lifestyle Funds, may buy illiquid and restricted
securities, but are restricted as to how much money they may invest in them. See
"Limitations" below.
 
DEPOSITORY RECEIPTS
 
All of the Funds in this prospectus, except the Lifestyle Funds, may invest in
ADRs. ADRs are certificates issued by a United States bank or trust company and
represent the right to receive securities of a foreign issuer deposited in a
domestic bank or foreign branch of a United States bank.
 
EDRs and GDRs are receipts evidencing an arrangement with a non-U.S. bank. We
consider ADRs, EDRs and GDRs to be foreign securities. The International Growth
Fund, the Small Cap Growth Fund, the International Value Fund and the MidCap
Value Fund may invest in EDRs and/or GDRs. The Large Cap Growth Fund may invest
in GDRs but may not invest in EDRs.

INVESTMENT FUNDS
 
Some countries have laws and regulations that currently preclude direct foreign
investment in the securities of their companies. However, indirect foreign
investment in the securities of companies listed and traded on the stock
exchanges in these countries is permitted through investment funds which have
been specifically authorized. The International Growth Fund, the Large Cap
Growth Fund, the Small Cap Growth Fund, the International Value Fund and the Mid
Cap Value Fund may invest in investment funds.
 
FOREIGN CURRENCY
 
All of the Funds, except the Lifestyle Funds, the S&P 500 Index Fund, the Mid
Cap Index Fund, the Small Cap Index Fund, the Large Cap Value Fund, the Small
Cap Value Fund, the Large Cap Growth Fund, the Mid Cap Growth Fund, the Small
Cap Growth Fund, the Balanced Fund, the Domestic Bond Fund and the Money Market
Fund, may buy and sell foreign currencies the same way they buy and sell other
investments. Funds buy foreign currencies when they believe the value of the
currency will increase. If it does increase, they sell the currency for a
profit. If it decreases they will experience a loss. Generally, the
International Growth Fund and the International Value Fund may also buy and sell
foreign currencies to settle transactions for foreign securities bought or sold
in the Fund.
 
The Funds, except the Lifestyle Funds, the S&P 500 Index Fund, the Mid Cap Index
Fund, the Small Cap Index Fund, the Large Cap Value Fund, the Small Cap Value
Fund, the Large Cap Growth Fund, the Mid Cap Growth Fund, the Small Cap Growth
Fund, the Balanced Fund, the Domestic Bond Fund the Money Market Fund, may
purchase forward foreign currency exchange contracts to protect against a
decline in the value of the U.S. dollar, to effect cross-hedges involving two
non-U.S. currencies, or for, settlement purposes.
 
WHEN-ISSUED SECURITIES
 
When-issued securities are those investments that have been announced by the
issuer and will be on the market soon. The Funds negotiate the price with a
broker before it goes on the market. If the security ends up selling on the
market at a lower price than negotiated, the Funds may have a loss. If it sells
at a higher price, the Funds may have a profit.
 
All of the Funds, other than the Lifestyle Funds, the Small Cap Growth Fund, the
Money Market Fund and the Mid Cap Value Fund, may buy when-issued securities in
accordance with their investment strategy.
 
MONEY MARKET SECURITIES
 
All of the Funds may invest part of their assets in high quality money market
securities payable in U.S. dollars. A listing of the types of money market
securities in which the Money Market Fund may invest in is in that Fund's Fact
Sheet. A money market security is high quality when it is rated in one of the
two highest credit categories by Moody's or S&P or another nationally recognized
rating service or if unrated, deemed high quality by VALIC or a Sub-adviser.
 
These high quality money market securities may include:
 
  - Cash and cash equivalents
 
  - Securities issued or guaranteed by the U.S. Government, its agencies or
    instrumentalities
 
  - Certificates of deposit and other obligations of domestic banks having total
    assets in excess of $1 billion
 
  - Commercial paper sold by corporations and finance companies
 
  - Corporate debt obligations with remaining maturities of 13 months or less
 
  - Repurchase agreements, money market securities of foreign issuers if payable
    in U.S. dollars, asset-backed securities, loan participations, and
    adjustable rate securities
 
INVESTMENT COMPANIES
 
Certain of the Funds may invest in the securities of other open-end or
closed-end investment companies. Under the 1940 Act, a Fund may invest no more
than 5% of its total assets in the securities of any one investment company nor
may it acquire more than 3% of the voting securities of any other investment
company. A Fund will indirectly bear its proportionate share of any management
fees paid by an investment company in which it invests.
 
The International Growth Fund, the Large Cap Growth Fund, the Large Cap Value
Fund, the Mid Cap Value Fund, the Small Cap Growth Fund, and the Small Cap Value
Fund each may invest in investment company securities in accordance with its
investment objectives.
 
DERIVATIVES
 
Unlike stocks and bonds that represent actual ownership of that stock or bond,
derivatives are investments which "derive" their value from securities issued by
a company, government, or government agency. In certain cases, derivatives may
be purchased for non-speculative investment purposes or to protect ("hedge")
against a change in the price of the underlying security. There are some
investors who take higher risk

("speculate") and buy derivatives to profit from a change in price of the
underlying security. We may purchase derivatives to hedge the investment
portfolios and to earn additional income in order to help achieve the Funds'
objectives. Generally, we do not buy derivatives to speculate.
 
The Funds, other than the Lifestyle Funds, the Money Market Fund, the Domestic
Bond Fund, the Balanced Fund, the Mid Cap Growth Fund and the International
Growth Fund may buy and sell derivatives, such as futures and/or options.
 
Options
 
An option is the right to buy or sell any type of investment for a preset price
over a specific period of time.
 
Call Option
 
For example, you can buy an option from Mr. Smith that gives you the right to
buy 10 shares of stock X at $25.00 per share anytime between now and six weeks
from now. You believe stock X will be selling for more than $25.00 per share
between now and then. Mr. Smith believes it won't be. If you exercise this
option before it expires, Mr. Smith must sell you 10 shares of stock X at $25.00
per share.
 
On the other hand, you can sell an option to Mr. Smith that gives him the right
to buy 10 shares of stock X at $25.00 per share anytime between now and six
weeks from now. You believe stock X will be selling for less than $25.00 per
share between now and then. Mr. Smith believes it won't be. If he exercises this
option before per share anytime between now and six weeks from now. In this
example, you believe stock X will be selling for less than $25.00 per share
between now and then. Mr. Smith thinks it will be selling for more.
 
Put Option
 
Or, you can buy an option from Mr. Smith that gives you the right to sell him 10
shares of X stock at $25.00 per share anytime between now and six weeks from
now. In this example, you believe stock X will be selling for less than $25.00
per share between now and then. Mr. Smith thinks it will be selling for more.
 
Or, you can sell an option to Mr. Smith that gives him the right to sell to you
10 shares of X stock at $25.00 per share anytime between now and six weeks from
now. In this example, he believes stock X will be selling for less than $25.00
per share between now and then.
 
The Funds use stock and bond futures to invest cash and cash equivalents. When
certain levels are reached the Fund will sell the futures and buy stocks or
bonds.
 
All of the Funds except the Lifestyle Funds, the Money Market Fund, the Domestic
Bond Fund, the Balanced Fund and the International Growth Fund may invest in one
or more of the following types of futures and options:
 
  - Write exchange traded covered put and call options on securities and stock
    indices.
 
  - Purchase exchange traded put and call options on securities and stock
    indices.
 
  - Purchase and sell exchange traded financial futures contracts.
 
  - Write covered call options and purchase exchange traded put and call options
    on financial futures contracts.
 
  - Write covered call options and purchase non-exchange traded call and put
    options on financial futures contracts.
 
The International Value Fund, the Large Cap Value Fund and the Small Cap Growth
Fund may write and purchase put and call options on securities and stock indices
that are not traded on an exchange.
 
SWAP AGREEMENTS
 
Swap agreements are contracts between parties in which one party agrees to make
payments to the other party based on the change in market value of a specified
index or asset. In return, the other party agrees to make payments to the first
party based on the return of a different specified index or asset. Additional
information about swap agreements is contained in the Statement of Additional
Information.
 
The Small Cap Value Fund, the Small Cap Growth Fund and the Small Cap Index Fund
may enter into swap agreements.
 
WARRANTS AND RIGHTS
 
Warrants and rights are instruments which entitle the holder to buy underlying
equity securities at a specific price for a specific period of time. A warrant
tends to be more volatile than its underlying securities and ceases to have
value if it is not exercised prior to its expiration date. Changes in the value
of a warrant do not necessarily correspond to changes in the value of its
underlying securities.
 
The International Growth Fund, the Large Cap Value Fund, the Large Cap Growth
Fund, the Small Cap Value Fund, the International Value Fund, the Balanced Fund,
the Domestic Bond Fund, the Small Cap Growth Fund and the Small Cap Index Fund
are authorized to use warrants or rights.
 
For more information about
SWAP AGREEMENTS, see the
Statement of Additional
Information.

REPURCHASE AGREEMENTS
 
A repurchase agreement requires the seller of the security to buy it back at a
set price at a certain time. If a Fund enters into a repurchase agreement, it is
really making a short term loan (usually for one day to one week). The Funds may
enter into repurchase agreements only with well-established securities dealers
or banks that are members of the Federal Reserve System. All the Funds in this
prospectus may invest in repurchase agreements.
 
The risk in a repurchase agreement is the failure of the seller to be able to
buy the security back. If the value of the security declines, the Fund may have
to sell at a loss.
 
A repurchase agreement of more than 7 days duration is illiquid. A discussion of
repurchase agreements, illiquid securities and Fund limitations is contained in
the Statement of Additional Information.
 
A WORD ABOUT RISK
 
There are five basic types of investment risk you may be subject to:
 
  - Market Risk
 
  - Credit (Financial) Risk
 
  - Interest Rate Risk
 
  - Risk Associated with Foreign Securities
 
  - Manager Risk (Lifestyle Funds only)
 
Generally stocks are considered to be subject to market risk, while debt
securities, such as U.S. government bonds and money market securities are
subject to interest rate risk. Other debt securities, such as corporate bonds,
involve both interest rate and credit (financial) risk. Lastly, risks associated
with foreign securities can involve political, currency and limited information
risks. Each of these types of investment risks is discussed below.
 
Market Risk
 
Market risk refers to the loss of capital resulting from changes in the prices
of investments. For example, market risk occurs when expectations of lower
corporate profits in general cause the broad market of stocks to fall in price.
When this happens, even though a company is experiencing growth in profits, the
price of its stock could fall.
 
Credit (Financial) Risk
 
Credit risk refers to the risk that the issuer of a bond may default or be
unable to pay interest or principal due on a bond.
 
To help the Funds' Investment Adviser or Sub-advisers decide which U.S.
corporate and foreign bonds to buy, they rely on Moody's and S&P (two nationally
recognized bond rating services), and on VALIC's and/or a Sub-adviser's own
research. This research lowers the risk of buying a bond of a company that may
not pay the interest and principal on the bond.
 
Certain of the Funds in this prospectus may buy bonds that are rated as
investment grade. There are four different levels of investment grade, from AAA
to BBB; see Description of Corporate Bond Ratings in the Statement of Additional
Information. All bonds with these ratings are considered to have adequate
ability to pay interest and principal.
 
All of the Funds in this prospectus may buy bonds issued by the U.S. Government.
The U.S. Government guarantees it will always pay principal and interest.
 
Interest Rate Risk
 
Interest rate risk refers to the risk that fluctuations in interest rates may
affect the value of interest paying securities in a Fund. If a fund sells a bond
before it matures, it may lose money, even if the bond is guaranteed by the U.S.
Government. Say, for example, a fund bought an intermediate government bond last
year that was paying interest at a fixed rate of 6%. Now, intermediate
government bonds are paying interest at a rate of 7%. If the fund wants to sell
the bond paying 6%, it will have to sell it at a discount (and realize a loss)
to attract buyers because they can buy new bonds paying 7% interest.
 
Manager Risk
 
The Lifestyle Funds, which do not hold securities directly, are subject to
manager risk, which is the possibility that the portfolio managers of the
underlying Funds may fail to execute the underlying Funds' investment strategies
effectively. As a result, the Lifestyle Funds may fail to meet their stated
objectives.
 
Risk Associated with Foreign Securities
 
Certain Funds may, subject to limits stated in the Fund's Fact Sheet, invest in
foreign securities including ADRs and securities of companies domiciled in
emerging market countries. A foreign security is a security issued by an entity
domiciled or incorporated outside of the U.S.
 
Among the principal risks of owning foreign securities:
 
Political risk -- the chance of a change in government and the assets of the
company being taken away.
 
Currency risk -- a change in the value of the foreign currency compared to the
dollar. If the foreign currency declines in value, your investment valued in
U.S. dollars will decline even if the value of the foreign stock or bond is
unchanged.

Statement of Additional
Information.

FOREIGN SECURITIES AND EMERGING
MARKETS, see the Statement

Limited information -- foreign companies generally are not regulated to the
degree U.S. companies are and may not report all of the information we are used
to getting. To minimize taxes they may not report some income or they may report
higher expenses.
 
INVESTMENT PRACTICES
 
Limitations
 
Each Fund has limitations on the percentage of its assets that it may allocate
to certain investments.
 
These limits are determined by the Fund's investment objectives and risk level.
 
For example, the S&P 500 Fund's investment goal is growth through investments
tracking the S&P 500 Index, an index that includes stocks of domestic and
foreign companies. As a result, this Fund may invest no more than 20% of its
assets in stocks that are not part of the S&P 500 Index.
 
Some Funds are restricted from buying certain types of investments altogether.
For example, the Money Market Fund may not invest in futures and options.
 
Each Fund's limitations are shown in the Investment Strategy section of its Fact
Sheet.
 
Lending Portfolio Securities
 
Each Fund, except the Lifestyle Funds, may lend its investment securities to
broker-dealers and other financial institutions to earn more money for the Fund.
Assets are placed in a special account by the borrower to cover the market value
of the securities on loan. The assets serving as collateral for the loan are
valued daily.
 
A risk of lending portfolio investments is that there may be a delay in the Fund
getting its investments back when a loaned security is sold.
 
The Funds will only make loans to broker-dealers and other financial
institutions approved by its Custodian, as monitored by VALIC and authorized by
the Board of Trustees.

LENDING PORTFOLIO SECURITIES, see

Information.

ABOUT THE SERIES COMPANY
- --------------------------------------------------------------------------------
 
SERIES COMPANY SHARES
 
The Series Company is an open-end mutual fund and may offer shares of the Funds
for sale at any time. However, the Series Company offers shares of the Funds
only to registered and unregistered separate accounts of VALIC, and its
affiliates, or employee thrift plans maintained by VALIC or American General
Corporation.
 
The Series Company was organized on May 6, 1998, under the laws of the state of
Delaware as a business trust, and presently is authorized to sell 18 series.
Each of these series is authorized to issue an unlimited number of shares of
beneficial interest, par value $0.01 per share.
 
The Series Company 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 two-thirds of the shares then outstanding cast
in person or by proxy at such meeting. The Series Company will assist such
holders in communicating with other shareholders of the Series Company to the
extent required by the 1940 Act. More detailed information concerning the Series
Company is set forth in the Statement of Additional Information.
 
The Series Company's Declaration of Trust provides that no Trustee, officer or
shareholder of the Series Company shall be held to any personal liability, nor
shall resort be had to their private property for the satisfaction of any
obligation or liability of the Series Company but the assets of the Fund only
shall be liable.
 
As a participant, you do not directly buy shares of the Funds that make up the
Series Company. Instead, you buy units in either a registered or unregistered
separate account of VALIC or of its affiliates. When you buy these units, you
specify which Funds you want the separate account to invest your money in. The
separate account, in turn, buys the shares of the Funds according to your
instructions. See your contract prospectus for more information on the separate
account associated with your contract.
 
When the separate accounts buy, sell, or transfer shares of the Funds, they do
not pay any charges related to these transactions.
 
As distributor, VAMCO sells shares of the Funds to the separate accounts. VAMCO
is a wholly owned subsidiary of VALIC and acts as a distributor under an
agreement it has with the Series Company. VAMCO does not charge the Series
Company or the separate accounts for its services. Also, VAMCO is not required
to sell a minimum number of shares to the separate accounts.
 
VAMCO sends orders to buy, sell or transfer shares to the Series Company's
transfer agent daily. The price of any share affected by the request is the next
net asset value calculated after order is received.
 
For more information on how to participate, see your contract prospectus.
 
   
NET ASSET VALUE OF THE SERIES COMPANY SHARES
    
 
How Net Asset Value is Calculated
 
Here is how the Series Company calculates the net asset value of each Fund's
shares:
 
<TABLE>
<S>  <C>                           <C>  <C>
Step 1:
     Total value of the Fund's
     assets* (including money           The Fund's
     owed to the fund but not yet       Total Net Asset
     collected)                      =  Value
- -    The Fund's liabilities
     (including money owed by the
     Fund but not yet paid)
 
Step 2:
     The Fund's total net asset
     value (from Step 1)
/    The total number of the
     Fund's shares that are             NET ASSET VALUE
     outstanding.                    =  PER SHARE
</TABLE>
 
- ---------------
 
* The Series Company uses the fair market value of Fund's
  investments to calculate the Fund's total value. However, it uses the
  amortized cost method to determine the values of all the Money Market Fund's
  investments and of any other Fund's short-term securities maturing within 60
  days. The amortized cost method approximates fair market value.
 
If a Fund's portfolio includes investments that are not sold often or are not
sold on any
 
THE VARIABLE ANNUITY
MARKETING COMPANY
(VAMCO) acts as the
Series Company's
distributor.
 
                                       52
<PAGE>   57
- --------------------------------------------------------------------------------
 
exchanges, the Series Company's Board of Trustees or its delegate will, in good
faith, estimate fair market value of these investments.
 
When Net Asset Value is Calculated
 
The Series Company calculates the net asset value of each Fund's shares at
approximately 4pm EST each day the New York Stock Exchange is open. (The New
York Stock Exchange is open Monday through Friday but is closed on certain
federal and other holidays.)
 
Through VAMCO, the separate accounts send orders to the Series Company to buy,
sell, or transfer shares based on requests received from participants.
 
DIVIDENDS AND CAPITAL GAINS
 
Dividends from Net Investment Income
 
Net investment income generally includes stock dividends received and bond
interest earned less expenses paid by the Fund. Each Fund pays dividends from
net investment income occasionally. Dividends from net investment income are
automatically reinvested for you into additional shares of the Fund. Each Fund,
except the Money Market Fund pays dividends quarterly. The Money Market Fund
pays dividends daily.
 
Distributions from Capital Gains
 
When a Fund sells a security for more than it paid for that security, a capital
gain results. Once a year, each Fund pays distributions from capital gains, as
long as total capital gains exceed total capital losses. Distributions from
capital gains are automatically reinvested for you into additional shares of the
Fund.
 
DIVERSIFICATION
 
Each Fund's diversification policy limits the amount that the Fund may invest in
certain securities. Each Fund's diversification policy is also designed to
comply with the diversification requirements of the Internal Revenue Code (the
"Code") as well as the 1940 Act.
 
All of the Funds, except the Lifestyle Funds, may, with respect to 75% of their
total assets, invest up to 5% of their total assets in a single issuer. An
issuer, or "company" does not include the U.S. Government or agencies of the
U.S. Government according to the Code and the 1940 Act. For diversification
purposes, repurchase agreements are considered to be issued by the U.S.
Government if backed by U.S. Government securities. Also, these Funds may not
own more than 10% of the voting securities of a company.
 
The Lifestyle Funds are "non-diversified" under the 1940 Act. This means that
each Fund can invest more of its assets in fewer issuers and for this reason may
be riskier than the other Funds. These Funds may invest up to 25% of their total
assets in a single issuer as long as those investments representing over 5% of
total assets in one issuer do not exceed 50% of total assets of a
 
                                       53
<PAGE>   58
 
- --------------------------------------------------------------------------------
 
Fund. The remaining 50% of total assets may not include more than 5% of total
assets in one issuer.
 
Also, the Money Market Fund may not invest more than 5% of its total assets in
any company rated as "second tier" by a national rating service (as described in
Types of Investments).
 
TAXES
 
By paying out all earnings as described in the Dividends and Capital Gains
section above and by complying with the diversification requirements under the
Code, each Fund expects to qualify as a Registered Investment Company (RIC)
under Subchapter M of the Code. By qualifying as a RIC the Fund will not have to
pay federal income taxes.
 
VOTING RIGHTS
 
One Vote Per Share
 
Each outstanding share has one vote on all matters that shareholders vote on. As
a participant, you vote on these matters indirectly by voting your units. The
way you vote your units as a participant depends on your contract. See your
contract prospectus for specific details.
 
When a matter comes up for vote, the separate account will vote its shares in
the same proportion as the unit votes it actually receives. If VALIC determines
that it may, under the current interpretation of the 1940 Act, vote shares
directly instead of voting through its units, it may decide to vote that way.
 
Shareholder Meetings
 
Delaware law does not require the Series Company to hold regular, annual
shareholder meetings. But, the Series Company must hold shareholder meetings on
the following matters:
 
  - to approve certain agreements as required by the 1940 Act;
 
  - to change fundamental investment objectives in the Diversification section
    and to change fundamental investment restrictions, above;
 
  - to fill vacancies on the Series Company's Board of Trustees if the
    shareholders have elected less than a majority of the Trustees.
 
Shareholder Communications
 
The Series Company will assist in shareholder communications.
 
YEAR 2000 RISKS
 
Like insurance companies, financial and business organizations around the world,
the Series Company Funds could be adversely affected if the computer systems
used by the Series Company, other service providers and entities with computer
systems that are linked to the Series Company's records do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly known as the "Year 2000 Issue." The Series Company is taking
steps that it believes are reasonably designed to address the Year 2000 Issue
with respect to the computer systems that it uses and to obtain satisfactory
assurances that comparable steps are being taken by each of the Series Company's
major service providers. The Series Company expects to be substantially complete
with its computer systems projects to address the Year 2000 Issue by the end of
1998. However, there can be no assurance that these steps will be sufficient to
avoid any adverse impact on the Series Company Funds.
 
REPORTS
 
The Series Company sends Annual Reports containing audited financial statements,
Semi-Annual Reports containing unaudited financial statements, and proxy
materials to contract owners or participants. Also, the Series Company includes
an Annual Report with each Statement of Additional Information it sends out.
 
If you have any questions about the Annual or Semi-Annual Reports, call or write
to the Series Company at the phone number / address found on the cover page of
this prospectus.
 
See the Statement of
Additional information and
your contract prospectus for
further tax discussions. You
should also consult your tax
advisor before investing.

                        GENERAL INFORMATION AND HISTORY
 
     American General Series Portfolio Company 3 (the "Series Company") was
organized as a Delaware business trust on May 6, 1998 by VALIC and is registered
under the Investment Company Act of 1940, as amended, (the "1940 Act") as an
open-end, management investment company. Pursuant to an Investment Advisory
Agreement with the Series Company and subject to the authority of the Series
Company's Board of Trustees, VALIC serves as the Series Company's investment
adviser and conducts the business and affairs of the Series Company.
Additionally, VALIC has engaged investment sub-advisers to provide investment
sub-advisory services for each Fund other than the American General Socially
Responsible Fund, the American General Money Market Fund, the American General
Conservative Growth Lifestyle Fund, the American General Moderate Growth
Lifestyle Fund and the American General Growth Lifestyle Fund, subject to
VALIC's control, direction and supervision. The Series Company consists of
eighteen separate investment portfolios (hereinafter collectively referred to as
the "Funds" or individually as a "Fund"), each of which is, in effect, a
separate mutual fund issuing its own separate class of shares of beneficial
interest.
 
     The Series Company issues shares of interest of each Fund to registered and
unregistered separate accounts of VALIC and its affiliates to fund variable
annuity or variable life contracts (the "Contracts"). Currently the Series
Company acts as an investment vehicle for assets of VALIC's Separate Account, a
unit investment trust registered as an investment company under the 1940 Act.
Additionally, retirement plans maintained by VALIC and American General
Corporation may own shares of certain of the Funds.
 
     The Series Company and VALIC have Codes of Ethics which establish for their
officers, directors and certain employees procedures and restrictions as to
those individual's personal investment trading activities.
 
                       PERFORMANCE AND YIELD INFORMATION
 
     The Series Company may compute the total return of a Fund ("Average Annual
Total Return"), total return of a Fund before expenses ("Portfolio Total
Return"), and compare Portfolio Total Return to the total return of the Fund's
benchmark index ("Index Total Return"). The difference between Portfolio Total
Return and Index Total Return is referred to as "tracking difference." Tracking
difference represents the amount that the return on the investment portfolio
(which results from the Adviser's investment selection) deviates from its
benchmark's Index Total Return. If you invest in a Fund through an annuity
contract, you should be aware that fund performance does not reflect contract
charges or separate account charges which will reduce Fund values which are
available to Participants. Information about Separate Account performance is
available in the applicable contract prospectus.
 
AVERAGE ANNUAL TOTAL RETURN
 
     Average Annual Total Return quotations for periods of 1, 3, 5, and 10
years, or, since inception of the Fund, are calculated according to the
following formula:
 
                                P (1+T)(n) = ERV
 
     Where:
 
<TABLE>
                 <S>     <C>
                 P     = A hypothetical initial Purchase Payment of $1,000.
                 T     = Average annual total return.
                 n     = Number of years.
                 ERV =   Ending redeemable value of a hypothetical $1,000 Purchase
                         Payment made at the beginning of the first period.
</TABLE>
 
     Average Annual Total Return reflects the deduction of Fund expenses and
assumes that all dividends and distributions are reinvested when paid.
 
PORTFOLIO TOTAL RETURN
 
     Portfolio Total Return quotations for periods of 1, 3, 5, and 10 years, or,
since inception are calculated by adding to the Average Total Annual Return
 
                                        4
<PAGE>   67
 
(described above) the expenses of the Fund. Expenses of the Fund are calculated
at the end of each Fund's fiscal year and are expressed as a percentage of
average net assets. Expenses as a percentage of average net assets are prorated
equally over the months in the fiscal year in which the ratio was calculated
when determining expenses for periods crossing over fiscal years.
 
INDEX TOTAL RETURN
 
     Index Total Return quotations for periods 1, 3, 5, and 10 years, or, since
inception, are calculated by determining the percentage change in value of the
benchmark index over the applicable period including reinvestment of dividends
and interest as applicable. Index Total Return is calculated according to the
formula described above for Average Annual Total Return, however it does not
include an expense component; if an expense component were included the return
would be lower.
 
SEVEN DAY YIELDS
 
     The American General Money Market Fund may quote a Seven Day Current Yield
and a Seven Day Effective Yield. The Seven Day Current Yield is calculated by
determining the total return for the current seven day period ("based period
return") and annualizing the base period return by dividing by seven days, then
multiplying the result by 365 days. The Seven Day Effective Yield annualizes the
base period return while compounding weekly the base period return according to
the following formula:
 
        Seven Day Effective Yield = [(Base Period Return + 1)(365/7)-1]
 
30 DAY CURRENT YIELD
 
     The Domestic Bond Fund may quote a 30 Day Current Yield which is determined
based on the current 30 day period, according to the following standardized
formula:
 
                           Yield = 2[(1 + NII )(6)-1]
                                    S X NAV
 
     Where:
 
<TABLE>
                 <S>  <C>  <C>
                 NII  =    Net investment income (interest income, plus dividend
                           income, plus other income, less fund expenses.
                 S    =    Average daily shares outstanding.
                 NAV  =    Net asset value per share on the last day of the period.

                      FUNDAMENTAL INVESTMENT RESTRICTIONS
 
     The Funds have each adopted certain fundamental investment restrictions
which, unlike the other investment objective(s), policies, and investment
program of each Fund, may only be changed with the consent of a majority of the
outstanding voting securities of the particular Fund. The 1940 Act defines such
a majority as the lesser of (1) 67% or more of the voting securities present in
person or by proxy at a shareholders' meeting, if the holders of more than 50%
of the outstanding voting securities of a Fund are present or represented by
proxy, or (2) more than 50% of a Fund's outstanding voting securities.
 
     Calculation of each Fund's total assets for compliance with any of the
following fundamental or non-fundamental investment restrictions or any other
investment restrictions set forth in the Series Company's prospectus or
Statement of Additional Information will not include cash collateral held in
connection with securities lending activities.
 
     The fundamental and, in certain cases, non-fundamental, investment
restrictions of each Fund are listed below. The percentage limitations
referenced in some of the restrictions are to be determined at the time of
purchase.
 
AMERICAN GENERAL S&P 500 INDEX FUND ("S&P 500 INDEX FUND") INVESTMENT
RESTRICTIONS
 
The S&P 500 Index Fund may not:
 
 (1) Borrow money or mortgage or hypothecate assets of the Fund, except that in
     an amount not to exceed 1/3 of the current value of the Fund's net assets,
     it may borrow money as a temporary measure for extraordinary or emergency
     purposes and enter into reverse repurchase agreements or dollar roll
     transactions, and except that it may pledge, mortgage or hypothecate not
     more than 1/3 of such assets to secure such borrowings (it is intended that
     money would be borrowed only from banks and only either to accommodate
     requests for the withdrawal of beneficial interests (redemption of shares)
     while effecting an orderly liquidation of portfolio securities or to
     maintain liquidity in the event of an unanticipated failure to complete a
     portfolio security transaction or other similar situations) or reverse
     repurchase agreements, provided that collateral arrangements with respect
     to options and futures, including deposits of initial deposit and variation
     margin, are not considered a pledge of assets for purposes of this
     restriction and except that assets may be pledged to secure letters of
     credit solely for the purpose of participating in a captive insurance
     company sponsored by the Investment Company Institute.
 
 (2) Underwrite securities issued by other persons except insofar as the Series
     Company (or the Fund) may technically be deemed an underwriter under the
     Securities Act of 1933 ("1933 Act") in selling a portfolio security.
 
 (3) Make loans to other persons except: (a) through the lending of the Fund's
     portfolio securities and provided that any such loans not exceed 30% of the
     Fund's total assets (taken at market value); (b) through the use of
     repurchase agreements or the purchase of short-term obligations; or (c) by
     purchasing a portion of an issue of debt securities of types distributed
     publicly or privately.
 
 (4) Purchase or sell real estate (including, limited partnership interests but
     excluding securities secured by real estate or interests therein),
     interests in oil, gas or mineral leases, commodities or commodity contracts
     (except futures and option contracts) in the ordinary course of business
     (except that the Fund) may hold and sell, for the Fund's portfolio, real
     estate acquired as a result of the Fund's ownership of securities).
 
 (5) Concentrate its investments in any particular industry (excluding U.S.
     government securities), but if it is deemed appropriate for the achievement
     of the Fund's investment objective, up to 25% of its total assets may be
     invested in any one industry.
 
 (6) Issue any senior security (as that term is defined in the 1940 Act) if such
     issuance is specifically prohibited by the 1940 Act or the rules and
     regulations promulgated thereunder, provided that collateral arrangements
     with respect to options and futures, including deposits of initial deposit
     and variation margin, are not considered to be the issuance of a senior
     security for purposes of this restriction.
 
 (7) Purchase securities issued by any investment company except by purchase in
     the open market where no commission or profit to a
 
                                        7
<PAGE>   70
 
     sponsor or dealer results from such purchase other than the customary
     broker's commission, or except when such purchase, though not made in the
     open market is part of a plan of merger or consolidation; provided,
     however, that securities of any investment company will not be purchased
     for the Fund if such purchase at the time thereof would cause: (a) more
     than 10% of the Fund's total assets (taken at the greater of cost or market
     value) to be invested in the securities of such issuers: (b) more than 5%
     of the Fund's total assets (taken at the greater of cost or market value)
     to be invested in any one investment company; or (c) more than 3% of the
     outstanding voting securities of any such issuer to be held for the Fund
     and, provided further that. except in the case of merger or consolidation,
     the Fund shall not invest in any other open-end investment company unless
     the Fund (1) waives the investment advisory fee with respect to assets
     invested in other open-end investment Companies and (2) incurs no sales
     charge in connection with the investment (as an operating policy, the Fund
     will not invest in another open-end registered investment company).
     Notwithstanding the foregoing, the Fund may invest all of its investable
     assets (cash, securities, and receivables relating to securities) in
     open-end management investment companies having substantially the same
     investment objective, policies and limitations as the Fund.
 
     Additional Restrictions. In order to comply with certain statutes and
policies, the Fund will not as a matter of operating policy:

     assets.
 
 (2) Pledge, mortgage or hypothecate for any purpose in excess of 10% of the
     Fund total assets (taken at market value), provided that collateral
     arrangements with respect to options and futures, including deposits of
     initial deposit and variation margin, are not considered a pledge of assets
     for purposes of this restriction.
 
 (3) Purchase any security or evidence of interest therein on margin, except
     that such short-term credit as may be necessary for the clearance of
     purchases and sales of securities may be obtained and except that deposits
     of initial deposit and variation margin may be made in connection with the
     purchase, ownership, holding or sale of futures.
 
 (4) Sell any security which it does not own unless by virtue of its ownership
     of other securities it has at the time of sale a right to obtain
     securities, without payment of further consideration, equivalent in kind
     and amount to the securities sold and provided that if such right is
     conditional the sale is made upon the same conditions.
 
 (5) Invest for the purpose of exercising control or management.
 
 (6) Invest more than 15% of the Fund's net assets (taken at the greater of cost
     or market value) in securities that are illiquid or not readily marketable

     liquid by the Board of Trustees, and (b) commercial paper that is sold

     cost or market value) in securities that are restricted as to resale under
     the 1933 Act (other than Rule 144A securities deemed liquid by the Board of

The Small Cap Index Fund may not:
 
 (1) Borrow money or mortgage or hypothecate assets of the Fund, except that in

     transactions, and except that it may pledge, mortgage or hypothecate not
     more than 1/3 of such assets to secure such borrowings (it is intended that
     money would be borrowed only from banks and only either to accommodate

     provided that collateral arrangements with respect to options and futures,

     that assets may be pledged to secure letters of credit solely for the
     purpose of participating in a captive insurance company sponsored by the
     Investment Company Institute.
 
 (2) Underwrite securities issued by other persons except insofar as the Series
     Company (or the Fund) may technically be deemed an underwriter under the
     1933 Act in selling a portfolio security.

     portfolio securities and provided that any such loans not exceed 30% of the

     portfolio, real estate acquired as a result of the Fund's ownership of
     securities).

     issuance is specifically prohibited by the 1940 Act or the rules and
     regulations promulgated thereunder, provided that collateral arrangements

     and variation margin, are not considered to be the issuance of a senior
     security for purposes of this restriction.
 
 (7) Purchase securities issued by any investment company except by purchase in
     the open market where no commission or profit to a sponsor or dealer
     results from such purchase other than the customary broker's commission, or

     plan of merger or consolidation; provided, however, that securities of any
     investment company will not be purchased for the Fund if such purchase at
     the time thereof would cause: (a) more than 10% of the Fund's total assets
     (taken at the greater of cost or market value) to be invested in the
     securities of such issuers; (b) more than 5% of the Fund's total assets

     (i) waives the investment advisory fee with respect to assets invested in
     other open-end investment companies and (ii) incurs no sales charge in
     connection with the investment (as an operating policy, the Fund will not
     invest in another open-end registered investment company). Notwithstanding
     the foregoing, the Fund may invest all of its investable assets (cash,
     securities, and receivables relating to securities) in open-end management
     investment companies having substantially the same investment objective,
     policies and limitations as the Fund.

(limitation number 8, above), the Sub-adviser has no present intention of

     obligations that are secured by real estate or securities issued by
     companies investing in real estate, such as real estate investment trusts.

     securities laws.

AMERICAN GENERAL LARGE CAP VALUE FUND ("LARGE CAP VALUE FUND") INVESTMENT
RESTRICTIONS
 
The Large Cap Value Fund may not:
 
 (1) Invest 25% or more of the value of its total assets in securities of
     companies primarily engaged in any one industry (other than the U.S.
     Government, its agencies and instrumentalities). Concentration may occur as
     a result of changes in the market value of portfolio securities, but may
     not result from investment.
 
 (2) Borrow money (including reverse repurchase agreements), except as a
     temporary measure for extraordinary or emergency purposes or to facilitate
     redemptions (not for leveraging or investment), provided that borrowings do
     not exceed an amount equal to 33 1/3% of the current value of the Fund's
     assets taken at market value, less liabilities other than borrowings. If at
     any time the Fund's borrowings exceed this limitation due to a decline in
     net assets, such borrowings will within three days be reduced to the extent
     necessary to comply with this limitation. The Fund will not purchase
     investments once borrowed funds (including reverse repurchase agreements)
     exceed 5% of its total assets.

     issuer (other than securities issued by the U.S. Government, its agencies,
     and instrumentalities), if immediately after and as a result of such
     investment the current market value of the Fund's holdings in the
     securities of such issuer exceeds 5% of the value of the Fund's assets.

     loan shall not include (i) the acquisition for investment of bonds,
     debentures, notes or other evidences of indebtedness of any corporation or
     government which are publicly distributed or of a type customarily
     purchased by institutional investors, or (ii) the entry into repurchase
     agreements or reverse repurchase agreements. The Fund may lend its
     portfolio securities to broker-dealers or other institutional investors if
     the aggregate value of all securities loaned does not exceed 33 1/3% of the
     value of the Fund's total assets.
 
 (6) Purchase or sell commodities or commodity futures contracts except that the
     Fund may enter into futures contracts and options thereon to the extent
     provided in its Prospectus.
 
 (7) Purchase or sell real estate or real estate mortgage loans; provided,
     however, that the Fund may invest in securities secured by real estate or
     interests therein or issued by compa-
 
                                       17

     nies which invest in real estate or interests therein.
 
 (8) Engage in the business of underwriting securities issued by others, except
     that the Fund will not be deemed to be an underwriter or to be underwriting
     on account of the purchase of securities subject to legal or contractual
     restriction on disposition.
 
 (9) Issue senior securities, except as permitted by its investment objective,
     policies and restrictions, and except as permitted by the 1940 Act.
 
(10) Purchase or sell puts, calls or invest in straddles, spreads or any
     combination thereof, if as a result of such purchase the value of the
     Fund's aggregate investment in such securities would exceed 5% of the
     Fund's total assets.
 
(11) Make short sales of securities or purchase any securities on margin, except
     for such short-term credits as are necessary for the clearance of
     transactions. The Fund may make initial margin deposits and variation
     margin payments in connection with transactions in futures contracts and
     related options.
 
(12) Purchase from or sell portfolio securities to its officers or directors or
     other interested persons (as defined in the 1940 Act) of the Fund,
     including their investment advisors and affiliates, except as permitted by
     the 1940 Act and exemptive rules or orders thereunder.
 
(13) Invest in securities issued by other investment companies except in
     connection with a merger, consolidation, acquisition of assets, or other
     reorganization approved by the Fund's shareholders and to the extent
     permitted by the 1940 Act; provided that the Fund may invest all of its
     investable assets (cash, securities, and receivables relating to
     securities) in open-end management investment companies having
     substantially the same investment objective, policies and limitations as
     the Fund.

     Fund's total assets, the Fund will reduce its borrowings within three days
     (excluding Sundays and holidays) to the extent necessary to comply with the
     33 1/3% limitation.
 
 (2) Purchase physical commodities or contracts thereon, unless acquired as a
     result of the ownership of securities or instruments, but this restriction
     shall not prohibit the Fund from purchasing futures contracts or options
     (including options on futures contracts, but excluding options or futures
     contracts on physical commodities) or from investing in securities of any
     kind. For purposes of the limitations on commodities, the Fund does not
     consider foreign currencies or forward contracts to be physical
     commodities.
 
 (3) With respect to 75% of the value of its total assets, purchase the
     securities of any issuer (other than securities issued or guaranteed by the
     U.S. Government or any of its agencies or instrumentalities) if, as a
     result, (i) more than 5% of the value of the Fund's total assets would be
     invested in the securities of that issuer or (ii) the Fund would hold more
     than 10% of the outstanding voting securities of that issuer.
 
 (4) Purchase any security if, as a result, 25% or more of its total assets
     (taken at current value) would be invested in the securities of issuers
     having their principal business activities in the same industry. This
     limitation does not apply to securities issued or guaranteed by
 
                                       18
<PAGE>   81
 
     the U.S. Government or its agencies or instrumentalities.
 
 (5) Lend any security or make any other loan if, as a result, more than 33 1/3%
     of its total assets (taken at current value) would be lent to other
     parties, except, in accordance with its investment objective, policies, and
     limitations, (i) through the purchase of a portion of an issue of debt
     securities or (ii) by engaging in repurchase agreements.
 
 (6) Purchase real estate unless acquired as a result of the ownership of
     securities or instruments, but this restriction shall not prohibit the Fund
     from purchasing securities issued by entities or investment vehicles that
     own or deal in real estate or interests therein or instruments secured by
     real estate or interests therein.
 
 (7) Issue senior securities, except as permitted under the 1940 Act.

     repurchase agreements, exceed 5% of its total assets.
 
(10) Except for the purchase of debt securities and engaging in repurchase

(11) Purchase securities on margin from brokers or other lenders, except that
     the Fund may obtain such short-term credits as are necessary for the
     clearance of securities transactions. Margin payments in connection with
     transactions in futures contracts and options on futures contracts shall
     not constitute the purchase of securities on margin and shall not be deemed
     to violate the foregoing limitation.
 
(12) Invest more than 10% of the value of its total assets in securities of
     foreign issuers, provided that the limitation shall not apply to foreign
     securities denominated in U.S. dollars, including American Depositary
     Receipts ("ADRs").
 
(13) Purchase any security if, as a result, more than 15% of its net assets
     would be invested in illiquid securities. Illiquid securities include
     securities that cannot be sold within seven days in the ordinary course of
     business for approximately the amount at which the Fund has valued the
     securities, such as repurchase agreements maturing in more than seven days.
 
     The Fund's investment limitations (9) through (13) are non-fundamental and
may be changed by the Board of Trustees without shareholder approval. In
addition, the Fund may invest all of its investable assets (cash, securities,

AMERICAN GENERAL SMALL CAP VALUE FUND ("SMALL CAP VALUE FUND") INVESTMENT
RESTRICTIONS
 
The Small Cap Value Fund may not:
 
 (1) Borrow money or mortgage or hypothecate assets of the Fund, except that in
     an amount not to exceed 1/3 of the current value of the Fund's assets, it
     may borrow money as a temporary measure for extraordinary or emergency
     purposes and enter into reverse repurchase agreements or dollar roll
     transactions, and except that it may pledge, mortgage or hypothecate not
     more than 1/3 of such assets to secure such borrowings (it is intended that
     money would be borrowed only from banks and only either to accommodate
     requests for the withdrawal of beneficial interests (redemption of shares)
     while effecting an orderly liquidation of portfolio securities or to
     maintain liquidity in the event of an unanticipated failure to complete a
     portfolio security transaction or other similar situations) or reverse
     repurchase agreements, provided that collateral arrangements with respect
     to options and futures, including deposits of initial deposit and variation
     margin, are not considered a pledge of assets for purposes of this
     restriction and except that assets may be pledged to secure letters of
     credit solely for the purpose of participating in a captive insurance
     company sponsored by the Investment Company Institute.
 
(2) Underwrite securities issued by other persons except insofar as the Series
    Company (or the Fund) may technically be deemed an underwriter under the
    1933 Act in selling a portfolio security.
 
                                       19
<PAGE>   82
 
(3) Make loans to other persons except: (a) through the lending of the Fund's
    portfolio securities and provided that any such loans not exceed 30% of the
    Fund's total assets (taken at market value); (b) through the use of
    repurchase agreements or the purchase of short-term obligations; or (c) by
    purchasing a portion of an issue of debt securities of types distributed
    publicly or privately.
 
(4) Purchase or sell real estate (including limited partnership interests but
    excluding securities secured by real estate or interests therein), interests
    in oil, gas or mineral leases, commodities or commodity contracts (except
    futures and option contracts) in the ordinary course of business (except
    that the Series Company may hold and sell, for the Fund's portfolio, real
    estate acquired as a result of the Fund's ownership of securities and the
    securities of companies that deal in real estate).
 
(5) Concentrate its investments in any particular industry (excluding U.S.
    Government securities), but if it is deemed appropriate for the achievement
    of a Fund's investment objective(s), up to 25% of its total assets may be
    invested in any one industry.
 
(6) Issue any senior security (as that term is defined in the 1940 Act) if such
    issuance is specifically prohibited by the 1940 Act or the rules and
    regulations promulgated thereunder, provided that collateral arrangements
    with respect to options and futures, including deposits of initial deposit
    and variation margin, are not considered to be the issuance of a senior
    security for purposes of this restriction.
 
(7) Purchase securities issued by any investment company except by purchase in
    the open market where no commission or profit to a sponsor or dealer results
    from such purchase other than the customary broker's commission, or except
    when such purchase, though not made in the open market, is part of a plan of
    merger or consolidation; provided, however, that securities of any
    investment company will not be purchased for the Fund if such purchase at
    the time thereof would cause: (a) more than 10% of the Fund's total assets
    (taken at the greater of cost or market value) to be invested in the
    securities of such issuers; (b) more than 5% of the Fund's total assets
    (taken at the greater of cost or market value) to be invested in any one
    investment company; or (c) more than 3% of the outstanding voting securities
    of any such issuer to be held for the Fund; provided further that, except in
    the case of a merger or consolidation, the Fund shall not purchase any
    securities of any open-end investment company unless the Fund (i) waives the
    investment advisory fee with respect to assets invested in other open-end
    investment companies and (ii) incurs no sales charge in connection with the
    investment (as an operating policy, the Fund will not invest in another
    open-end registered investment company). Notwithstanding the foregoing, the
    Fund may invest all of its investable assets (cash, securities, and
    receivables relating to securities) in open-end management investment
    companies having substantially the same investment objective, policies and
    limitations as the Fund.
 
     Additional Restrictions. In order to comply with certain statutes and
policies the Fund will not as a matter of operating policy:

     Fund's total assets (taken at market value), provided that collateral

     initial deposit and variation margin, and reverse repurchase agreements are
     not considered a pledge of assets for purposes of this restriction.
 
 (3) Purchase any security or evidence of interest therein on margin, except
     that such short-term credit as may be necessary for the clearance of
     purchases and sales of securities may be obtained and except that deposits
     of initial deposit and variation margin may be made in connection with the
     purchase, ownership, holding or sale of futures.
 
 (4) Sell securities it does not own such that the dollar amount of such short
     sales at any one time exceeds 25% of the net equity of the Fund, and the
     value of securities of any one issuer in which the Fund is short exceeds
     the lesser of 2.0% of the value of the Fund's net assets or 2.0% of the
     securities of any class of
                                       20
<PAGE>   83
 
     any U.S. issuer and, provided that short sales may be made only in those
     securities which are fully listed on a national securities exchange or a
     foreign exchange (This provision does not include the sale of securities of
     the Fund contemporaneously owns or has the right to obtain securities
     equivalent in kind and amount to those sold, i.e., short sales against the
     box.) (The Fund has no current intention to engage in short selling).

     Board of Trustees).
 
 (7) Invest more than 15% of the Fund's net assets (taken at the greater of cost
     or market value) in securities that are illiquid or not readily marketable
     not including (a) Rule 144A securities that have been determined to be
     liquid by the Board of Trustees; and (b) commercial paper that is sold
     under section 4(2) of the 1933 Act which: (i) is not traded flat or in
     default as to interest or principal; and (ii) is rated in one of the two
     highest categories by at least two nationally recognized statistical rating
     organizations and the Board of Trustees have determined the commercial
     paper to be liquid; or (iii) is rated in one of the two highest categories
     by one nationally recognized statistical rating agency and the Board of
     Trustees have determined that the commercial paper is equivalent quality
     and is liquid.
 
 (8) Invest more than 5% of the Fund's total assets in securities issued by
     issuers which (including predecessors) have been in operation less than
     three years.
 
 (9) With respect to 75% of the Fund's total assets, purchase securities of any
     issuer if such purchase at the time thereof would cause the Fund to hold
     more than 10% of any class of securities of such issuer, for which purposes
     all indebtedness of an issuer shall be deemed a single class and all

                              INVESTMENT PRACTICES
 
REPURCHASE AGREEMENTS
 
     Each Fund may hold commercial paper, certificates of deposits, and
government obligations (including government guaranteed obligations) subject to
repurchase agreements with certain well established domestic banks and certain
broker-dealers, including primary government securities dealers, approved as
creditworthy by the Board of Trustees. The underlying security must be a
high-quality domestic money market security (except for the International Growth
Fund and the International Value Fund, which may utilize foreign money market
securities) and the seller must be a well established securities dealer or bank
that is a member of the Federal Reserve System. For the Money Market Fund, the
underlying security must be a U.S. Government security or a security rated in
the highest rating category by the Requisite NRSROs (Nationally Recognized
Statistical Rating Organization) and must be determined to present minimal
credit risk. Repurchase agreements are generally for short periods, often less
than a week. Repurchase agreements typically obligate a seller, at the time it
sells securities to a Fund, to repurchase the securities at a specific future
time and price. The price for which the Fund resells the securities is
calculated to exceed the price the Fund initially paid for the same securities,
thereby determining the yield during the Fund's holding period. This results in
a fixed market rate of interest, agreed upon by that Fund and the seller, which
is accrued as ordinary income. Most repurchase agreements mature within seven
days although some may have a longer duration. The underlying securities
constitute collateral for these repurchase agreements, which are considered
loans under the 1940 Act.
 
     The Funds do not intend to sell the underlying securities subject to a
repurchase agreement (except to the seller upon maturity of the agreement).
During the term of the repurchase agreement, the Funds (i) retain the securities
subject to the repurchase agreement as collateral securing the seller's
obligation to repurchase the securities, (ii) monitor on a daily basis the
market value of the securities subject to the repurchase agreement, and (iii)
require the seller to deposit with the Series Company's custodian collateral
equal to any amount by which the market value of the securities subject to the
repurchase agreement falls below the resale amount provided under the repurchase
agreement. In the event that a seller defaults on its obligation to repurchase
the securities, the Funds must hold the securities until they mature or may sell
them on the open market, either of which may result in a loss to a Fund if, and
to the extent that, the values of the securities decline. Additionally, the
Funds may incur disposition expenses when selling the securities. Bankruptcy
proceedings by the seller may also limit or delay realization and liquidation of
the collateral by a Fund and may result in a loss to that Fund. The Board of
Trustees of the Series Company will evaluate the creditworthiness of all banks
and broker-dealers with which the Series Company proposes to enter into
repurchase agreements. The Funds will not invest in repurchase agreements that
do not mature within seven days if any such investment, together with any
illiquid assets held by a Fund, exceeds 10% of the value of that Fund's total
assets (15% in the case of the S&P 500 Index Fund, the Small Cap Index Fund, the
International Growth Fund, the Large Cap Growth Fund, the Small Cap Growth Fund,
the Large Cap Value Fund, the Mid Cap Value Fund and the Small Cap Value Fund).
 
LENDING PORTFOLIO SECURITIES
 
     For purposes of realizing additional income, each Fund, except the
Lifestyle Funds, may make secured loans of its portfolio securities. Securities
loans are made to broker-dealers and other financial institutions approved by
State Street Bank and Trust Company (the "Custodian"), custodian to the Funds
and pursuant to agreements requiring that the loans be continuously secured by
collateral at least equal at all times to the loaned securities marked to market
on a daily basis. VALIC will monitor the activities of the Custodian as
authorized by the Board of Trustees. The collateral received will consist of
cash, U.S. government securities, letters of credit or such other collateral as
permitted by interpretations or rules of the Securities and Exchange Commission
("SEC"). While the securities are on loan, the Funds will continue to receive
the equivalent of the interest or dividends paid by the issuer on the
securities, as well as interest on the investment of the collateral or a fee
from the borrower.
 
     Any loan of portfolio securities by any Fund will be callable at any time
by the lending Fund upon notice of five business days. When voting or consent
rights which accompany loaned securities
                                       28
<PAGE>   91
 
pass to the borrower, the lending Fund will call the loan, in whole or in part
as appropriate, to permit the exercise of such rights if the matters involved
would have a material effect on that Fund's investment in the securities being
loaned. If the borrower fails to maintain the requisite amount of collateral,
the loan will automatically terminate, and the lending Fund will be permitted to
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 receiving additional collateral or in the
recovery of the securities or, 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 be made only when State Street, as
monitored by VALIC, considers the borrowing broker-dealers or financial
institutions to be creditworthy and of good standing and the interest earned
from such loans to justify the attendant risks. On termination of the loan, the
borrower will be required to return the securities to the lending Fund. Any gain
or loss in the market price during the loan would inure to the lending Fund. The
lending Fund may pay reasonable finders', administrative, and custodial fees in
connection with a loan of its securities.
 
REVERSE REPURCHASE AGREEMENTS
 
     Certain of the Funds may enter into reverse repurchase agreements. In a
reverse repurchase agreement, a Fund sells a security and agrees to repurchase
the same security at a mutually agreed upon date and price. For purposes of the
1940 Act a reverse repurchase agreement is also considered as the borrowing of
money by the Fund and, therefore, a form of leverage. The Funds will invest the
proceeds of borrowings under reverse repurchase agreements. In addition, a Fund
will enter into a reverse repurchase agreement only when the interest income to
be earned from the investment of the proceeds is greater than the interest
expense of the transaction. A Fund will not invest the proceeds of a reverse
repurchase agreement for a period which exceeds the duration of the reverse
repurchase agreement. Each Fund will establish and maintain with the Custodian a
separate account with a segregated portfolio of securities in an amount at least
equal to its purchase obligations under its reverse repurchase agreements.
 
CONVERTIBLE SECURITIES
 
     Certain Funds may invest in convertible securities of foreign or domestic
issues. A convertible security is a security (a bond or preferred stock) which
may be converted at a stated price within a specified period of time into a
certain quantity of the common stock of the same or a different issuer.
Convertible securities are senior to common stocks in a corporation's capital
structure but are usually subordinated to similar nonconvertible securities.
Convertible securities provide, through their conversion feature, an opportunity
to participate in capital appreciation resulting from a market price advance in
a convertible security's underlying common stock. The price of a convertible
security is influenced by the market value of the underlying common stock and
tends to increase as the market value of the underlying stock rises, whereas it
tends to decrease as the market value of the underlying stock declines.
 
FOREIGN SECURITIES
 
     A foreign security is a security issued by an entity domiciled or
incorporated outside of the United States.
 
     Included within the definition of foreign securities are American
Depository Receipts (ADRs), European Depositary Receipts (EDRs) and Global
Depository Receipts (GDRs).
 
     ADRs are certificates issued by a United States bank or trust company and
represent the right to receive securities of a foreign issuer deposited in a
domestic bank or foreign branch of a United States bank and traded on a United
States exchange or in an over-the-counter market. Generally, ADRs are in
registered form. Investment in ADRs has certain advantages over direct
investment in the underlying foreign securities since: (i) ADRs are U.S.
dollar-denominated investments that are easily transferable and for which market
quotations are readily available, and (ii) issuers whose securities are
represented by ADRs are generally subject to auditing, accounting and financial
reporting standards similar to those applied to domestic issuers. EDRs and GDRs
are receipts evidencing an arrangement with a non-U.S. bank similar to that for
ADRs and are designed for use in the non-U.S. securities markets. EDRs and GDRs
are not necessarily quoted in the same currency as the underlying security. In
addition, the Funds may invest in other types of depositary securities such as
 
                                       29
<PAGE>   92
 
international depository receipts, global depository shares, European depository
shares and international depository shares.
 
     A Fund may also, in accordance with its specific investment objective(s)
and investment program, policies and restrictions purchase U.S. dollar-
denominated money market securities of foreign issuers. Such money market
securities may be registered domestically and traded on domestic exchanges or in
the over-the-counter market (e.g., Yankee securities) or may be (1) registered
abroad and traded exclusively in foreign markets or (2) registered domestically
and issued in foreign markets (e.g., Eurodollar securities).
 
     In addition, all the Funds, except the Lifestyle Funds, the Large Cap
Growth Fund, the Large Cap Value Fund, the S&P 500 Index Fund, the Mid Cap Fund,
the Small Cap Index Fund and the Money Market Fund, may invest in non-U.S.
dollar-denominated foreign securities, in accordance with their specific
investment objective(s), investment programs, policies, and restrictions.
Investing in foreign securities may involve advantages and disadvantages not
present in domestic investments. There may be less publicly available
information about securities not registered domestically, or their issuers, than
is available about domestic issuers or their domestically registered securities.
Stock markets outside the U.S. may not be as developed as domestic markets, and
there may also be less government supervision of foreign exchanges and brokers.
Foreign securities may be less liquid or more volatile than U.S. securities.
Trade settlements may be slower and could possibly be subject to failure. In
addition, brokerage commissions and custodial costs with respect to foreign
securities may be higher than those for domestic investments. Accounting,
auditing, financial reporting and disclosure standards for foreign issuers may
be different than those applicable to domestic issuers. Non-U.S.
dollar-denominated foreign securities may be affected favorably or unfavorably
by changes in currency exchange rates and exchange control regulations
(including currency blockage) and a Fund may incur costs in connection with
conversions between various currencies. Foreign securities may also involve
risks due to changes in the political or economic conditions of such foreign
countries, the possibility of expropriation of assets or nationalization, and
possible difficulty in obtaining and enforcing judgments against foreign
entities.
 
EMERGING MARKETS
 
     Investments in companies domiciled in emerging market countries may be
subject to additional risks. Specifically, volatile social, political and
economic conditions may expose investments in emerging or developing markets to
economic structures that are generally less diverse and mature. Emerging market
countries may have less stable political systems than those of more developed
countries. As a result, it is possible that recent favorable economic
developments in certain emerging market countries may be suddenly slowed or
reversed by unanticipated political or social events in such countries.
Moreover, the economies of individual emerging market countries may differ
favorably or unfavorably from the US economy in such respects as the rate of
growth in gross domestic product, the rate of inflation, capital reinvestment,
resource self-sufficiency and balance of payments position.
 
     Another risk is that the small current size of the markets for such
securities and the currently low or nonexistent volume of trading can result in
a lack of liquidity and in greater price volatility. Until recently, there has
been an absence of a capital market structure or market-oriented economy in
certain emerging market countries. If a Fund's securities will generally be
denominated in foreign currencies, the value of such securities to the Fund will
be affected by changes in currency exchange rates and in exchange control
regulations. A change in the value of a foreign currency against the U.S. dollar
will result in a corresponding change in the U.S. dollar value of a Fund's
securities. In addition, some emerging market countries may have fixed or
managed currencies which are not free-floating against the U.S. dollar. Further,
certain emerging market currencies may not be internationally traded. Certain of
these currencies have experienced a steady devaluation relative to the U.S.
dollar. Many emerging markets countries have experienced substantial, and in
some periods extremely high, rates of inflation for many years. Inflation and
rapid fluctuations in inflation rates have had, and may continue to have,
negative effects on the economies and securities markets of certain emerging
market countries.
 
     A further risk is that the existence of national policies may restrict a
Fund's investment opportunities and may include restrictions on investment in
issuers or industries deemed sensitive to national interests. Also, some
emerging markets countries
 
                                       30
<PAGE>   93
 
may not have developed structures governing private or foreign investment and
may not allow for judicial redress for injury to private property.
 
FOREIGN CURRENCY EXCHANGE TRANSACTIONS
 
     Foreign currency transactions used by the Funds may be either: (i) on the
spot (i.e., cash) basis at the spot rate prevailing in the foreign exchange
market, or (ii) conducted through the use of forward foreign currency exchange
contracts. A forward foreign currency exchange contract involves an obligation
to purchase or sell a specific currency at a future date. In general, forward
foreign currency exchange contracts are not guaranteed by a third party and,
accordingly, each party to a forward foreign currency exchange contract is
dependent upon the creditworthiness and good faith of the other party.
 
     A Fund will enter into forward foreign currency exchange contracts only
under two circumstances. First, a Fund may enter into a forward foreign currency
exchange contract to purchase an amount of foreign currency to protect itself
against a possible loss that might occur between trade and settlement dates for
a particular security, resulting from a decline in the U.S. dollar against the
foreign currency in which such security is denominated. This practice may limit
the potential gains that might result from a positive change in such currency
relationships. Second, when VALIC or a Sub-adviser believes that the currency of
a particular foreign country may suffer or enjoy a substantial movement against
the U.S. dollar, a Fund may enter into a forward foreign currency exchange
contract to purchase or sell an amount of foreign currency approximating the
value of some or all of that Fund's portfolio securities denominated in such
foreign currency. The forecasting of short-term currency market movements is
extremely difficult and it is uncertain whether such short-term hedging
strategies will be successful.
 
STANDARD AND POOR'S DEPOSITORY RECEIPTS
 
     The Large Cap Growth Fund may, consistent with its objectives, purchase
Standard & Poor's Depository Receipts ("SPDR's"). SPDRs are American Stock
Exchange-traded securities that represent ownership in the SPDR Trust, a trust
which has been established to accumulate and hold a portfolio of common stocks
that is intended to track the price performance and dividend yield of the S&P
500. This trust is sponsored by a subsidiary of the American Stock Exchange.
SPDRs may be used for several reasons, including but not limited to:
facilitating the handling of cash flows or trading, or reducing transaction
costs. The use of SPDRs would introduce additional risk to the Large Cap Growth
Fund as the price movement of the instrument does not perfectly correlate with
the price action of the underlying index.
 
WHEN-ISSUED SECURITIES
 
     Each of the Funds except the Lifestyle Funds, the Money Market Fund and the
Mid Cap Value Fund may purchase securities on a when-issued or delayed delivery
basis. When such transactions are negotiated, the price of such securities is
fixed at the time of commitment, but delivery and payment for the securities may
take place a month or more after the date of the commitment to purchase. The
securities so purchased are subject to market fluctuation, and no interest
accrues to the purchaser during this period. Forward commitments involve a risk
of loss if the value of the security to be purchased declines prior to the
settlement date. VALIC does not believe that a Fund's net asset value or income
will be adversely affected by the purchase of securities on a when-issued basis.
 
DEBT SECURITIES
 
     Debt securities are considered high-quality if they are rated at least A by
Moody's or its equivalent by any other NRSRO or, if unrated, are determined to
be of equivalent investment quality. High-quality debt securities are considered
to have a very strong capacity to pay principal and interest. Debt securities
are considered investment grade if they are rated, for example, at least Baa by
Moody's or its equivalent by any other NRSRO or, if not rated, are determined to
be of equivalent investment quality. Investment grade debt securities are
regarded as having an adequate capacity to pay principal and interest.
Lower-medium and lower-quality securities rated, for example, Ba and B by
Moody's or its equivalent by any other NRSRO are regarded on balance as high
risk and predominantly speculative with respect to the issuer's continuing
ability to meet principal and interest payments. See the Section regarding
"Description of Corporate Bond Ratings" for a description of each rating
category in this Statement of Additional Information for a more complete
description of lower-medium and lower-quality debt securities and their risks.
 
                                       31
<PAGE>   94
 
     The maturity of debt securities may be considered long (ten plus years),
intermediate (one to ten years), or short-term (thirteen months or less). In
general, the principal values of longer-term securities fluctuate more widely in
response to changes in interest rates than those of shorter-term securities,
providing greater opportunity for capital gain or risk of capital loss. A
decline in interest rates usually produces an increase in the value of debt
securities, while an increase in interest rates generally reduces their value.
 
ZERO COUPON BONDS
 
     The Large Cap Value Fund, Mid Cap Value Fund, Balanced Fund and Domestic
Bond Fund may invest in zero coupon securities, which are debt obligations that
do not entitle the holder to any periodic payment of interest prior to maturity
or that specify a future date when the securities begin to pay current interest.
Zero coupon securities are issued and traded at a discount from their face
amount or par value. This discount varies depending on prevailing interest
rates, the time remaining until cash payments begin, the liquidity of the
security, and the perceived credit quality of the issuer.
 
     The discount on zero coupon securities ("original issue discount") must be
taken into income ratably by a Fund prior to the receipt of any actual payments.
Because the Fund must distribute substantially all of its net income to its
shareholders each year for income and excise tax purposes, the Fund may have to
dispose of portfolio securities under disadvantageous circumstances to generate
cash, or may be required to borrow, to satisfy its corresponding Fund's
distribution requirements.
 
     The market prices of zero coupon securities generally are more volatile
than the prices of securities that pay interest periodically. Zero coupon
securities are likely to respond to changes in interest rates to a greater
degree than other types of debt securities having a similar maturity and credit
quality.
 
REAL ESTATE SECURITIES AND REAL ESTATE INVESTMENT TRUSTS ("REITS")
 
     Each Fund other than the Lifestyle Funds and the Domestic Bond Fund may
invest in real estate securities. Real estate securities are equity securities
consisting of (i) common stocks, (ii) rights or warrants to purchase common
stocks, (iii) securities convertible into common stocks and (iv) preferred
stocks issued by real estate companies. A real estate company is one that
derives at least 50% of its revenues from the ownership, construction,
financing, management or sale of commercial, industrial, or residential real
estate or that has at least 50% of its assets invested in real estate.
 
     Certain Funds also may invest in REITs. REITs are pooled investment
vehicles which invest primarily in income producing real estate or real estate
related loans or interest. REITs are generally classified as equity REITs,
mortgage REITs or a combination of equity and mortgage REITs. Equity REITs
invest the majority of their assets directly in real property and derive income
primarily from the collection of rents. Equity REITs can also realize capital
gains by selling properties that have appreciated in value. Mortgage REITs
invest the majority of their assets in real estate mortgages and derive income
from the collection of interest payments. Like regulated investment companies
such as the Funds, REITs are not taxed on income distributed to shareholders
provided they comply with certain requirements under the Code. A Fund will
indirectly bear its proportionate share of any expenses paid by REITs in which
it invests in addition to the expenses paid by a Fund.
 
     Investing in REITs involves certain unique risks. Equity REITs may be
affected by changes in the value of the underlying property owned by such REITs,
while mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skills, are not diversified (except to the
extent the Code requires), and are subject to the risks of financing projects.
REITs are subject to heavy cash flow dependency, default by borrowers,
self-liquidation, and the possibilities of failing to qualify for the exemption
from tax for distributed income under the Code and failing to maintain their
exemptions from the 1940 Act. REITs (especially mortgage REITs) are also subject
to interest rate risks.
 
WARRANTS
 
     Warrants are securities that give the Funds the right to purchase equity
securities from the issuer at a specific price (the "strike price") for a
limited period of time. Warrants do not entitle a holder to dividends or voting
rights with respect to the underlying securities and do not represent any rights
in the assets of the issuing company. In addition, the value of warrants does
not, necessarily, in all cases
                                       32
<PAGE>   95
 
change to the same extent as the value of the underlying securities to which
they relate. Warrants cease to have value if they are not exercised prior to the
expiration date. These factors can make warrants more speculative than other
types of investments.
 
SWAP AGREEMENTS
 
     Certain of the Funds may enter into swap agreements. Swap agreements are
contracts between parties in which one party agrees to make payments to the
other party based on the change in the market value of a specified index or
asset. In return, the other party agrees to make payments to the first party
based on the return of a different specified index or asset. Swap agreements
entail the risk that a party will default on its payment obligations thereunder.
Swap agreements also bear the risk that a Fund will not be able to meet its
obligation to the counterparty. The risk may be mitigated if a Fund invests in
the specific assets for which it is obligated to pay a return.
 
EURODOLLAR OBLIGATIONS
 
     Certain Funds, in accordance with their investment objective(s), policies,
and investment program, may invest in Eurodollar obligations, including
Eurodollar bonds and Eurodollar certificates of deposit. A Eurodollar obligation
is a security denominated in U.S. dollars and originated principally in Europe,
giving rise to the term Eurodollar.
 
     Such securities are not registered with the SEC and generally may only be
sold to U.S. investors after the initial offering and cooling-off periods. The
market for Eurodollar securities is dominated by foreign-based investors and the
primary trading market for these securities is London.
 
     Eurodollar obligations, including Eurodollar bonds and Eurodollar
certificates of deposit, are principally obligations of foreign branches of U.S.
banks. These instruments represent the loan of funds actually on deposit in the
U.S. The Series Company believes that the U.S. bank would be liable in the event
that its foreign branch failed to pay on its U.S. dollar denominated
obligations. Nevertheless, the assets supporting the liability could be
expropriated or otherwise restricted if located outside the U.S. Exchange
controls, taxes, or political and economic developments also could affect
liquidity or repayment. Due to possibly conflicting laws or regulations, the
foreign branch of the U.S. bank could maintain and prevail that the liability is
solely its own, thus exposing a Fund to a possible loss. Such U.S. dollar
denominated obligations of foreign branches of Federal Deposit Insurance
Corporation ("FDIC") member U.S. banks are not covered by the usual $100,000 of
FDIC insurance if they are payable only at an office of such a bank located
outside the U.S., Puerto Rico, Guam, American Samoa, and the Virgin Islands.
 
     Moreover, there may be less publicly available information about foreign
issuers whose securities are not registered with the SEC and such foreign
issuers may not be subject to the accounting, auditing, and financial reporting
standards applicable to issuers registered domestically. In addition, foreign
issuers, stock exchanges, and brokers generally are subject to less government
regulation. There are, however, no risks of currency fluctuation since the
obligations are U.S. dollar denominated.
 
ASSET-BACKED SECURITIES
 
     Certain Funds may invest in asset-backed securities (unrelated to first
mortgage loans) that represent fractional interests in pools of retail
installment loans, both secured (such as certificates for automobile
receivables) and unsecured, and leases, or revolving credit receivables both
secured and unsecured (such as credit card receivable securities). These assets
are generally held by a trust and payments of principal and interest, or
interest only are passed through monthly or quarterly to certificate holders and
may be guaranteed up to certain amounts by letters of credit issued by a
financial institution affiliated or unaffiliated with the trustee or originator
of the trust.
 
     Underlying automobile sales contracts, leases or credit card receivables
are subject to prepayment, which may reduce the overall return to certificate
holders. Nevertheless, principal repayment rates tend not to vary much with
interest rates and the short-term nature of the underlying loans, leases, or
receivables tends to dampen the impact of any change in the prepayment level.
Certificate holders may also experience delays in payment on the certificates if
the full amounts due on underlying loans, leases or receivables are not realized
by the trust because of unanticipated legal or administrative costs of enforcing
the contracts or because of depreciation or damage to the collateral (usually
automobiles) securing certain contracts, or other
                                       33
<PAGE>   96
 
factors. If consistent with its investment objective(s) and policies, a Fund may
invest in other asset-backed securities that may be developed in the future.
 
MORTGAGE-BACKED SECURITIES
 
     Certain of the Funds may invest in Government National Mortgage Association
("GNMA") Certificates. GNMA Certificates are securities representing part
ownership of a pool of mortgage loans. These loans, issued by lenders such as
mortgage bankers, commercial banks, and savings and loan associations, are
either insured by the Federal Housing Administration or guaranteed by the
Veterans Administration. Each pool of mortgage loans is assembled and, after
being approved by GNMA, is offered to investors through securities dealers in
the form of certificates representing participations in the pool. Once approved
by GNMA, the timely payment of interest and principal of each mortgage is
guaranteed by GNMA and backed by the full faith and credit of the U.S.
Government. GNMA Certificates differ from bonds in that principal is paid
monthly by the borrower over the term of the loan rather than returned in a lump
sum at maturity. GNMA Certificates are called "pass-through" certificates
because both principal and interest payments (including prepayments) are passed
through to the holder of the certificate.
 
     The average life of GNMA Certificates varies with the maturities of the
underlying mortgage instruments. Upon receipt, principal payments may be used by
the Funds to purchase additional GNMA Certificates or other U.S. Government
Securities. In addition, prepayments of the mortgages included in the underlying
mortgage pool will usually result in the return of the greatest part of
principal invested well before the maturity of the mortgages in the pool. The
volume of such prepayments of principal in a given pool of mortgages will
influence the actual yield of the GNMA Certificate, and principal returned to
the Funds may be reinvested in instruments whose yield may be higher or lower
than that which might have been obtained had such prepayments not occurred. In
quoting yields of GNMA Certificates, the standard practice is to assume that the
certificates will have a 12 year life. As previously noted, however, the actual
life of an individual pool may differ widely and actual yield may differ
significantly from estimated yields based on the 12 year life assumption.
 
     Certain Funds may also invest in collateralized mortgage obligations
("CMOs") issued by governmental or nongovernmental entities, such as banks and
other mortgage lenders. Non-governmental securities may offer a higher yield but
may be subject to greater price fluctuation and risk than governmental
securities.
 
     CMOs are obligations fully collateralized directly or indirectly by a pool
of mortgages on which payments of principal and interest are passed through to
the holders of the CMOs on the same schedule as they are received, although not
necessarily on a pro rata basis. In reliance on an SEC interpretation, the
Funds' investments in certain qualifying CMOs are not subject to legal
limitations on acquiring interests in other investment companies. In order to be
able to rely on the SEC's interpretation, the CMOs must be unmanaged,
fixed-asset issuers that (i) invest primarily in mortgage-backed securities,
(ii) do not issue redeemable securities, (iii) operate under general exemptive
orders exempting them from all provisions of the Investment Company Act, and
(iv) are not registered or regulated under the Investment Company Act as
investment companies. To the extent that a Fund selects CMOs that do not meet
the above requirements, the Fund may not invest more than 10% of its assets in
all such entities and may not acquire more than 3% of the voting securities of
any single such entity.
 
LOAN PARTICIPATIONS
 
     Loan Participations are debt obligations of corporations and are usually
purchased from major money center banks, selected regional banks, and major
foreign banks with branches in the U.S. which are regulated by the Federal
Reserve System or appropriate state regulatory authorities. VALIC and the
Sub-advisers believe that the credit standards imposed by such banks are
comparable to the standards such banks use in connection with loans originated
by them and in which they intend to maintain a full interest. The financial
institutions offering loan participations do not guarantee principal or interest
on the loan participations which they offer. VALIC and the Sub-advisers will not
purchase such securities for the Funds unless they believe that the collateral
underlying the corporate loans is adequate and the corporation will be able, in
a timely fashion, to pay scheduled interest and principal amounts.
 
                                       34
<PAGE>   97
 
ADJUSTABLE RATE SECURITIES
 
     Certain of the Funds may invest in adjustable rate money market securities.
Adjustable rate securities (i.e., variable rate and floating rate instruments)
are securities that have interest rates that are adjusted periodically,
according to a set formula. The maturity of some adjustable rate securities may
be shortened under certain special conditions described more fully below.
 
     Variable rate instruments are obligations (usually certificates of deposit)
that provide for the adjustment of their interest rates on predetermined dates
or whenever a specific interest rate changes. A variable rate instrument whose
principal amount is scheduled to be paid in 13 months or less is considered to
have a maturity equal to the period remaining until the next readjustment of the
interest rate. Many variable rate instruments are subject to demand features
which entitle the purchaser to resell such securities to the issuer or another
designated party, either (1) at any time upon notice of usually 30 days or less,
or (2) at specified intervals, not exceeding 13 months, and upon 30 days notice.
A variable rate instrument subject to a demand feature is considered to have a
maturity equal to the longer of the period remaining until the next readjustment
of the interest rate or the period remaining until the principal amount can be
recovered through demand.
 
     Floating rate instruments (generally corporate notes, bank notes, or
Eurodollar certificates of deposit) have interest rate reset provisions similar
to those for variable rate instruments and may be subject to demand features
like those for variable rate instruments. The maturity of a floating rate
instrument is considered to be the period remaining until the principal amount
can be recovered through demand.
 
ILLIQUID SECURITIES
 
     The Funds will not invest more than 10% (15% in the case of S&P 500 Index
Fund, the Small Cap Index Fund, the International Growth Fund, the Small Cap
Growth Fund, the Large Cap Growth Fund, the Large Cap Value Fund, the Mid Cap
Value Fund and the Small Cap Value Fund), of the value of their assets in
securities or other investments that are illiquid or not readily marketable
(including repurchase agreements with maturities exceeding seven days).
Securities received as a result of a corporate reorganization or similar
transaction affecting readily-marketable securities already held in the
portfolio of a Fund will not be considered securities or other investments that
are not readily marketable. However, the Funds will attempt, in an orderly
fashion, to dispose of any securities received under these circumstances, to the
extent that such securities are considered not readily marketable, and together
with other illiquid securities, exceed 10% (or 15%) of the value of a Fund's net
assets.
 
RULE 144A SECURITIES
 
     Each Fund, other than the Lifestyle Funds, may purchase securities which,
while privately placed, are eligible for purchase and sale pursuant to Rule 144A
under the 1933 Act. This Rule permits certain qualified institutional buyers,
such as the Funds, to trade in privately placed securities even though such
securities are not registered under the 1933 Act. The Series Company, under the
supervision of the Board of Trustees, will consider whether securities purchased
under Rule 144A are illiquid and thus subject to the Funds' restriction on
investing more than 10% (15% in the case of the S&P 500 Index Fund, the Small
Cap Index Fund, the International Growth Fund, the Small Cap Growth Fund, the
Large Cap Growth Fund, the Large Cap Value Fund, the Mid Cap Value Fund and the
Small Cap Value Fund) of its assets in illiquid securities. Determination of
whether a Rule 144A security is liquid or not is a question of fact. In making
this determination the Series Company will consider the trading markets for the
specific security taking into account the unregistered nature of a Rule 144A
security. In addition the Series Company could consider (i) frequency of trades
and quotes, (ii) number of dealers and potential purchasers, (iii) dealer
undertakings to make a market, and (iv) nature of the security and market place
trades (for example, the time needed to dispose of the security, the method of
soliciting offers and the mechanics of transfer). The liquidity of Rule 144A
securities will also be monitored by the Series Company and, if, as a result of
changed conditions, it is determined that a Rule 144A security is no longer
liquid, the Funds' holding of illiquid securities will be reviewed to determine
what, if any, action is required to assume that the Funds do not invest more
than 10% (or 15%) of their assets in illiquid securities. Investing in Rule 144A
securities could have the effect of increasing the amount of the Funds'
investments in illiquid securities if qualified
                                       35

institutional buyers are unwilling to purchase such securities.
 
OPTIONS ON SECURITIES AND SECURITIES INDICES
 
     Each Fund, other than the Large Cap Growth Fund, the Mid Cap Growth Fund,
the International Value Fund, the Balanced Fund, the Domestic Bond Fund, the
International Growth Fund, and the Money Market Fund, may write covered call and
put options on securities and securities indices. The Mid Cap Value Fund may
write covered call options and purchase call options in related closing
transactions only. A call option is a contract that gives to the holder the
right to buy a specified amount of the underlying security or currency at a
fixed or determinable price (called the exercise or "strike" price) upon
exercise of the option. A put option is a contract that gives the holder the
right to sell a specified amount of the underlying security or currency at a
fixed or determinable price upon exercise of the option.
 
     To "cover" a call option written, a Fund may, for example, identify and
have available for sale the specific portfolio security, group of securities, or
foreign currency to which the option relates. To cover a put option written, a
Fund may, for example, establish a segregated asset account with its custodian
containing cash or liquid assets that, when added to amounts deposited with its
broker or futures commission merchant ("FCM") as margin, equals the market value
of the instruments underlying the put option written.
 
     Certain Funds may write options on securities and securities indices. If a
Fund writes an option which expires unexercised or is closed out by the Fund at
a profit, it will retain the premium received for the option, which will
increase its gross income. If the price of the underlying security or currency
moves adversely to the Fund's position, the option may be exercised and the
Fund, as the writer of the option, will be required to sell or purchase the
underlying security or currency at a disadvantageous price, which may only be
partially offset by the amount of premium received.
 
     Options on stock indices are similar to options on stock, except that all
settlements are made in cash rather than by delivery of stock, and gains or
losses depend on price movements in the stock market generally (or in a
particular industry or segment of the market represented by the index) rather
than price movements of individual stocks. When a Fund writes an option on a
securities index, and the underlying index moves adversely to the Fund's
position, the option may be exercised. Upon such exercise, the Fund, as the
writer of the option, will be required to pay in cash an amount equal to the
difference between the exercise settlement value of the underlying index and the
exercise price of the option, multiplied by a specified index "multiplier."
 
     Call or put options on a stock index may be written at an exercise or
"strike" price which is either below or above the current value of the index. If
the exercise price at the time of writing the option is below the current value
of the index for a call option or above the current value of the index for a put
option the option is considered to be "in the money." In such a case, the Fund
will cover such options written by segregating with its custodian or pledging to
its commodity broker as collateral cash, U.S. Government or other high-grade,
short-term debt obligations equal in value to the amount by which the option
written is in the money, times the multiplier, times the number of contracts.
 
     Stock indices for which options are currently traded include the S&P 500
Index, Value Line Index, National OTC Index, Major Market Index, Computer
Technology Index, Oil Index, NYSE Options Index, Technology Index, Gold/Silver
Index, Institutional Index and NYSE Beta Index. The Funds may also use options
on such other indices as may now or in the future be available.
 
     Each Fund, except the Large Cap Growth Fund, the Mid Cap Growth Fund, the
International Growth Fund, the International Value Fund, the Mid Cap Value Fund,
the Balanced Fund, the Domestic Bond Fund and the Money Market Fund, may also
purchase put or call options on securities and securities indices in order to
(i) hedge against anticipated changes in interest rates or stock prices that may
adversely affect the prices of securities that the Fund intends to purchase at a
later date, (ii) hedge its investments against an anticipated decline in value,
or (iii) attempt to reduce the risk of missing a market or industry segment
advance. Certain Funds also may purchase put options on foreign currencies that
correlate with the Fund's portfolio securities in order to minimize or hedge
against anticipated declines in the exchange rate of the currencies in which the
Fund's securities are denominated and may purchase call options on foreign
currencies that correlate with its portfolio securities to take advantage of
anticipated increases
                                       36
<PAGE>   99
 
in exchange rates. In the event that the anticipated changes in interest rates,
stock prices, or exchange rates occur, the Fund may be able to offset the
resulting adverse effect on the Fund, in whole or in part, through the options
purchased.
 
     The premium paid for a put or call option plus any transaction costs will
reduce the benefit, if any, realized by the Fund upon exercise or liquidation of
the option, and, unless the price of the underlying security, securities index,
or currency changes sufficiently, the option may expire without value to the
Fund. To close option positions purchased by the Funds, the Funds may sell put
or call options identical to options previously purchased, which could result in
a net gain or loss depending on whether the amount received on the sale is more
or less than the premium and other transaction costs paid on the put or call
option purchased.
 
     Options used by the Funds may be traded on the national securities
exchanges or in the over-the-counter market. Only the Large Cap Value Fund and
the Small Cap Growth Fund may use over-the-counter options. Options traded in
the over-the-counter market may not be as actively traded as those on an
exchange. Accordingly, it may be more difficult to value such options. In
addition, it may be more difficult to enter into closing transactions with
respect to options traded over-the-counter. In this regard, the Funds may enter
into contracts with the primary dealers with whom they write over-the-counter
options. The contracts will provide that each Fund has the absolute right to
repurchase an option it writes at any time at a repurchase price which
represents the fair market value of such option, as determined in good faith
through negotiations between the parties, but which in no event will exceed a
price determined pursuant to a formula contained in the contract. Although the
specific details of the formula may vary between contracts with different
primary dealers, the formula will generally be based on a multiple of the
premium received by each Fund for writing the option, plus the amount, if any,
of the option's intrinsic value (i.e., the amount the option is "in-the-money").
The formula will also include a factor to account for the difference between the
price of the security and the strike price of the option if the option is
written "out-of-the-money." Although the specific details of the formula may
vary with different primary dealers, each contract will provide a formula to
determine the maximum price at which each Fund can repurchase the option at any
time. The Funds have established standards of creditworthiness for these primary
dealers.
 
WRITING COVERED CALL AND PUT OPTIONS AND PURCHASING CALL AND PUT OPTIONS
 
     All of the Funds, except the Mid Cap Growth Fund, the International Growth
Fund, the International Value Fund, the Large Cap Growth Fund, the Balanced
Fund, the Domestic Bond Fund and the Money Market Fund, may write
exchange-traded covered call and put options on or relating to specific
securities in order to earn additional income or, in the case of a call written,
to minimize or hedge against anticipated declines in the value of the Fund's
securities. The Mid Cap Value Fund may write exchange-traded covered call
options, but not put options in this connection. To "cover" an option means, for
example, to identify and make available for sale the specific portfolio security
or foreign currency to which the option relates. Through the writing of a
covered call option a Fund receives premium income but obligates itself to sell
to the purchaser of such an option the particular security or foreign currency
underlying the option at a specified price at any time prior to the expiration
of the option period, regardless of the market value of the security or the
exchange rate for the foreign currency during this period. Through the writing
of a covered put option a Fund receives premium income but obligates itself to
purchase a particular security or foreign currency underlying the option at a
specified price at any time prior to the expiration of the option period,
regardless of market value or exchange rate during the option period.
 
     Certain Funds, in accordance with their investment objective(s) and
investment programs, may also write exchange-traded covered call and put options
on stock indices and may purchase call and put options on stock indices that
correlate with the Fund's portfolio securities. These Funds may engage in such
transactions for the same purposes as they may engage in such transactions with
respect to individual portfolio securities or foreign currencies, that is, to
generate additional income or as a hedging technique to minimize anticipated
declines in the value of the Fund's portfolio securities or the exchange rate of
the securities in which the Fund invested. In economic effect, a stock index
call or put option is similar to an option on a particular security, except that
the value of the option depends on the weighted value of the group of securities
comprising the index, rather than a particular secur-
                                       37
<PAGE>   100
 
ity, and settlements are made in cash rather than by delivery of a particular
security.
 
     Each Fund, other than the Large Cap Growth Fund, the Mid Cap Growth Fund,
the International Growth Fund, the International Value Fund, the Balanced Fund,
the Domestic Bond Fund and the Money Market Fund, may also purchase exchange-
traded call and put options with respect to securities and stock indices that
correlate with that Fund's particular portfolio securities. In this connection,
the Mid Cap Value Fund may purchase exchange traded call options only.
 
     A Fund may purchase put options for defensive purposes in order to protect
against an anticipated decline in the value of its portfolio securities or
currencies. As the holder of a put option with respect to individual securities
or currencies, the Fund has the right to sell the securities or currencies
underlying the options and to receive a cash payment at the exercise price at
any time during the option period. As the holder of a put option on an index, a
Fund has the right to receive, upon exercise of the option, a cash payment equal
to a multiple of any excess of the strike price specified by the option over the
value of the index.
 
     A Fund may purchase call options on individual securities, currencies or
stock indices in order to take advantage of anticipated increases in the price
of those securities or currencies by purchasing the right to acquire the
securities or currencies underlying the option or, with respect to options on
indices, to receive income equal to the value of such index over the strike
price. As the holder of a call option with respect to individual securities or
currencies, a Fund obtains the right to purchase the underlying securities or
currencies at the exercise price at any time during the option period. As the
holder of a call option on a stock index, a Fund obtains the right to receive,
upon exercise of the option, a cash payment equal to the multiple of any excess
of the value of the index on the exercise date over the strike price specified
in the option.
 
     Unlisted options may be used by the Large Cap Value Fund and the Small Cap
Growth Fund. Such options are not traded on an exchange and may not be as
actively traded as listed securities, making the valuation of these securities
more difficult. In addition, an unlisted option entails a risk not found in
connection with listed options -- that the party on the other side of the option
transaction will default. This may make it impossible to close out an unlisted
option position in some cases, and profits may be lost thereby. Such unlisted,
over-the-counter options, unless otherwise indicated, will be considered
illiquid securities. The Funds will engage in such transactions only with firms
of sufficient credit to minimize these risks. In instances in which a Fund has
entered into agreements with primary dealers with respect to the unlisted,
over-the-counter options it has written, and such agreements would enable the
Fund to have an absolute right to repurchase, at a pre-established formula
price, the over-the-counter options written by it, the Fund will treat as
illiquid only the amount equal to the formula price described above less the
amount by which the option is "in-the-money."
 
     Although these investment practices will be used to generate additional
income and to attempt to reduce the effect of any adverse price movement in the
securities or currencies subject to the option, they do involve certain risks
that are different in some respects from investment risks associated with
similar funds which do not engage in such activities. These risks include the
following: writing covered call options -- the inability to effect closing
transactions at favorable prices and the inability to participate in the
appreciation of the underlying securities or currencies above the exercise
price; writing covered put options -- the inability to effect closing
transactions at favorable prices and the obligation to purchase the specified
securities or currencies or to make a cash settlement on the stock index at
prices which may not reflect current market values or exchange rates; and
purchasing put and call options -- possible loss of the entire premium paid. In
addition, the effectiveness of hedging through the purchase or sale (writing) of
stock index options will depend upon the extent to which price movements in the
portion of a Fund's portfolio being hedged correlate with price movements in the
selected stock index. Perfect correlation may not be possible because the
securities held or to be acquired by a Fund may not exactly match the
composition of the stock index on which options are purchased or written. If the
forecasts of VALIC regarding movements in securities prices, currencies or
interest rates are incorrect, a Fund's investment results may have been better
without the hedge.
 
FINANCIAL FUTURES CONTRACTS
 
     Each Fund, except the Mid Cap Growth Fund, the International Growth Fund,
the International Value Fund, the Mid Cap Value Fund, the Bal-
                                       38

anced Fund, the Domestic Bond Fund and the Money Market Fund, in accordance with
its investment objective(s), investment program, policies, and restrictions may
purchase and sell exchange-traded financial futures contracts as a hedge to
protect against anticipated changes in prevailing interest rates, overall stock
prices or currency rates, or to efficiently and in a less costly manner
implement either increases or decreases in exposure to the equity or bond
markets. The Funds may also write covered call options and purchase put and call
options on financial futures contracts for the same purposes or to earn
additional income and the Small Cap Growth Fund, the Large Cap Value Fund and
the Large Cap Growth Fund may also write covered put options on stock index
futures contracts. The Large Cap Value Fund may utilize currency futures
contracts and both listed and unlisted financial futures contracts and options
thereon.
 
     Financial futures contracts consist of interest rate futures contracts,
stock index futures contracts, and currency futures contracts. An interest rate
futures contract is a contract to buy or sell specified debt securities at a
future time for a fixed price. A stock index futures contract is similar in
economic effect, except that rather than being based on specific securities, it
is based on a specified index of stocks and not the stocks themselves. A
currency futures contract is a contract to buy or sell a specific foreign
currency at a future time for a fixed price.
 
     An interest rate futures contract binds the seller to deliver to the
purchaser on a specified future date a specified quantity of one of several
listed financial instruments, against payment of a settlement price specified in
the contract. A public market currently exists for futures contracts on GNMA
Certificates, long-term U.S. Treasury Bonds, three-month U.S. Treasury Bills,
short-term U.S. Treasury Notes, and bank certificates of deposit.
 
     Stock index futures contracts bind purchaser and seller to deliver, at a
future date specified in the contract, a cash amount equal to a multiple of the
difference between the value of a specified stock index on that date and the
settlement price specified by the contract. That is, the seller of the futures
contract must pay and the purchaser would receive a multiple of any excess of
the value of the index over the settlement price, and conversely, the purchaser
must pay and the seller would receive a multiple of any excess of the settlement
price over the value of the index. A public market currently exists for stock
index futures contracts based on the S&P 500 Index, the New York Stock Exchange
Composite Index, the Value Line Stock Index, and the Major Market Index. It is
expected that financial instruments related to broad-based indices, in addition
to those for which futures contracts are currently traded, will in the future be
the subject of publicly-traded futures contracts, and the Funds may use any of
these, which are appropriate, in its hedging strategies.
 
     A financial futures contract is an agreement to buy or sell a security (or
deliver a final cash settlement price, in the case of a contract relating to an
index or otherwise not calling for physical delivery of a specified security)
for a set price in the future. Exchange-traded futures contracts are designated
by boards of trade which have been designated "contracts markets" by the
Commodity Futures Trading Commission ("CFTC").
 
     Positions taken in the futures markets are not normally held until delivery
or cash settlement is required, but instead are liquidated through offsetting
transactions which may result in a gain or a loss. While futures positions taken
by a Fund will usually be liquidated in this manner, the Fund may instead make
or take delivery of underlying securities whenever it appears economically
advantageous to the Fund to do so. A clearing organization associated with the
relevant exchange assumes responsibility for closing out transactions and
guarantees that, as between the clearing members of an exchange, the sale and
purchase obligations will be performed with regard to all positions that remain
open at the termination of the contract.
 
     Unlisted financial futures contracts, which may be purchased or sold only
by the Large Cap Value Fund, like unlisted options, are not traded on an
exchange and, generally, are not as actively traded as listed futures contracts
or listed securities. Such financial futures contracts generally do not have the
following elements: standardized contract terms, margin requirements relating to
price movements, clearing organizations that guarantee counter-party
performance, open and competitive trading in centralized markets, and public
price dissemination. These elements in listed instruments serve to facilitate
their trading and accurate valuation. As a result, the accurate valuation of
unlisted financial futures contracts may be difficult. In addition, it may be
difficult or even impossible, in some cases,
 
                                       39
<PAGE>   102
 
to close out an unlisted financial futures contract, which may, in turn, result
in significant losses to the Fund. Such unlisted financial futures contracts
will be considered by the Fund to be illiquid securities and together with other
illiquid securities will be limited to no more than 10% (or 15%) of the value of
such Fund's total assets. In making such determination, the value of unlisted
financial futures contracts will be based upon the "face amount" of such
contracts.
 
     When financial futures contracts are entered into by a Fund, either as the
purchaser or the seller of such contracts, the Fund is required to deposit with
its custodian in a segregated account in the name of the FCM an initial margin
of cash or U.S. Treasury bills equaling as much as 5% to 10% or more of the
contract settlement price. The nature of initial margin requirements in futures
transactions differs from traditional margin payments made in securities
transactions in that initial margins for financial futures contracts do not
involve the borrowing of funds by the customer to finance the transaction.
Instead, a customer's initial margin on a financial futures contract represents
a good faith deposit securing the customer's contractual obligations under the
financial futures contract. The initial margin deposit is returned, assuming
these obligations have been met, when the financial futures contract is
terminated. In addition, subsequent payments to and from the FCM, called
"variation margin," are made on a daily basis as the price of the underlying
security, stock index, or currency fluctuates, reflecting the change in value in
the long (purchase) or short (sale) positions in the financial futures contract,
a process known as "marking to market."
 
     A Fund, as an internal operating policy, may not hold financial futures
contracts in an amount greater than 33% of the Fund's net assets. A Fund may not
adhere to this internal operating policy in circumstances where the Fund is
required to invest a large cash infusion. In this circumstance the Fund's total
invested position, including the security value of the financial futures
contracts may not exceed 100% of the Fund's net assets.
 
     Financial futures contracts generally are not entered into to acquire the
underlying asset and generally are not held to term. Prior to the contract
settlement date, the Funds will normally close all futures positions by entering
into an offsetting transaction which operates to cancel the position held, and
which usually results in a profit or loss.
 
OPTIONS ON FINANCIAL FUTURES CONTRACTS
 
     For bona fide hedging purposes, each Fund, except the Mid Cap Growth Fund,
the International Growth Fund, the International Value Fund, the Balanced Fund,
the Domestic Bond Fund and the Money Market Fund, may also purchase call and put
options on financial futures contracts and write call options on financial
futures contracts of the type which the particular Fund is authorized to enter
into. Except for options on currency futures contracts used by the International
Equities Fund and the International Government Bond Fund, options on financial
future contracts used by the Funds are traded on exchanges that are licensed and
regulated by the CFTC. A call option on a financial futures contract gives the
purchaser the right in return for the premium paid, to purchase a financial
futures contract (assume a "long" position) at a specified exercise price at any
time before the option expires. A put option gives the purchaser the right, in
return for the premium paid, to sell a financial futures contract (assume a
"short" position), for a specified exercise price, at any time before the option
expires.
 
     Unlike entering into financial futures contracts, purchasing options on
financial futures contracts allows a Fund to decline to exercise the option,
thereby avoiding any loss beyond foregoing the purchase price (or "premium")
paid for the options. Therefore, the purchase of options on financial futures
contracts may be a preferable hedging strategy when a Fund desires maximum
flexibility. Whether, in order to achieve a particular objective, a Fund enters
into a financial futures contract, on the one hand, or an option contract, on
the other, will depend on all the circumstances, including the relative costs,
liquidity, availability and capital requirements of such financial futures and
options contracts. Also, the Funds will consider the relative risks involved,
which may be quite different. These factors, among others, will be considered in
light of market conditions and the particular objective to be achieved.
 
CERTAIN ADDITIONAL RISKS OF OPTIONS AND FINANCIAL FUTURES CONTRACTS
 
     In addition to the risks described in the Series Company's Prospectus, the
use of options and financial futures contracts may entail the following
 
                                       40
<PAGE>   103
 
risks. First, although such instruments when used by the Funds are intended to
correlate with the Funds' portfolio securities or currencies, in many cases the
options or financial futures contracts used may be based on securities,
currencies, or stock indices the components of which are not identical to the
portfolio securities owned or intended to be acquired by the Funds. Second, due
to supply and demand imbalances and other market factors, the price movements of
financial futures contracts, options thereon, currency options, and stock index
options may not necessarily correspond exactly to the price movements of the
securities, currencies, or stock indices on which such instruments are based.
Accordingly, there is a risk that a Fund's transactions in those instruments
will not in fact offset the impact on the Fund of adverse market developments in
the manner or to the extent contemplated or that such transactions will result
in losses to the Fund which are not offset by gains with respect to
corresponding portfolio securities owned or to be purchased by that Fund.
 
     To some extent, these risks can be minimized by careful management of
hedging activities. For example, where price movements in a financial futures or
option contract are expected to be less volatile than price movements in the
related portfolio securities owned or intended to be acquired by a Fund, it may,
in order to compensate for this difference, use an amount of financial futures
or option contracts which is greater than the amount of such portfolio
securities. Similarly, where the price movement of a financial futures or option
contract is anticipated to be more volatile, a Fund may use an amount of such
contracts which is smaller than the amount of portfolio securities to which such
contracts relate.
 
     The risk that the hedging technique used will not actually or entirely
offset an adverse change in a Fund's portfolio securities is particularly
relevant to financial futures contracts and options written on stock indices and
currencies. A Fund, in entering into a futures purchase contract, potentially
could lose any or all of the contract's settlement price. In entering into a
futures sale contract, a Fund could potentially lose a sum equal to the excess
of the contract's value (marked to market daily) over the contract's settlement
price. In writing options on stock indices or currencies a Fund could
potentially lose a sum equal to the excess of the value of the index or currency
(marked to market daily) over the exercise price. In addition, because financial
futures contracts require delivery at a future date of either a specified
security or currency, or an amount of cash equal to a multiple of the difference
between the value of a specified stock index on that date and the settlement
price, an algebraic relationship exists between any price movement in the
underlying security or currency or index and the potential cost of settlement to
a Fund. A small increase or decrease in the value of the underlying security or
currency or stock index can, therefore, result in a much greater increase or
decrease in the cost to the Fund.
 
     Stock index call options written also pose another risk as hedging tools.
Because exercises of stock index options are settled in cash, there is an
inherent timing risk that the value of a Fund's portfolio securities "covering"
a stock index call option written by it may decline during the time between
exercise of the option by the option holder and notice to the Fund of such
exercise (usually one day or more) thereby requiring the Fund to use additional
assets to settle the transaction. This risk is not present in the case of
covered call options on individual securities, which are settled by delivery of
the actual securities.
 
     There are also special risks in using currency options including the
following: (i) settlement of such options must occur in the country issuing the
currency in conformity with foreign regulations for such delivery, including the
possible imposition of additional costs and taxes, (ii) no systematic reporting
of "last sale" information for foreign currencies, and (iii) the need to use
"odd lot" transactions for underlying currencies at prices less favorable than
those for "round lot" transactions.
 
     Although the Funds intend to establish positions in these instruments only
when there appears to be an active market, there is no assurance that a liquid
market for such instruments will exist when a Fund seeks to "close out" (i.e.
terminate) a particular financial futures contract or option position. This is
particularly relevant for over-the-counter options and financial futures
contracts, as previously noted. Trading in such instruments could be
interrupted, for example, because of a lack of either buyers or sellers. In
addition, the futures and options exchanges may suspend trading after the price
of such instruments has risen or fallen more than the maximum amount specified
by the exchange. Exercise of options could also be restricted or delayed because
of regulatory restrictions or other factors. A Fund
                                       41
<PAGE>   104
 
may be able, by adjusting investment strategy in the cash or other contract
markets, to offset to some extent any adverse effects of being unable to
liquidate a hedge position. Nevertheless, in some cases, a Fund may experience
losses as a result of such inability. Therefore it may have to liquidate other
more advantageous investments to meet its cash needs.
 
     In addition, FCMs or brokers in certain circumstances will have access to a
Fund's assets posted as margin in connection with these transactions as
permitted under the 1940 Act. See "Other Information Custody of Assets" in this
Statement of Additional Information. The Funds will use only FCMs or brokers in
whose reliability and financial soundness they have full confidence and have
adopted certain other procedures and limitations to reduce the risk of loss with
respect to any assets which brokers hold or to which they may have access.
Nevertheless, in the event of a broker's insolvency or bankruptcy, it is
possible that a Fund could experience a delay or incur costs in recovering such
assets or might recover less than the full amount due. Also the value of such
assets could decline by the time a Fund could effect such recovery.
 
     The success of a Fund in using hedging techniques depends, among other
things, on VALIC's ability to predict the direction and volatility of price
movements in both the futures and options markets as well as the securities
markets and on VALIC's ability to select the proper type, time, and duration of
hedges. There can be no assurance that these techniques will produce their
intended results. In any event, VALIC will use financial future contracts,
options thereon, currency options and stock index options only when it believes
the overall effect is to reduce, rather than increase, the risks to which a Fund
is exposed. Hedging transactions also, of course, may be more, rather than less,
favorable to a Fund than originally anticipated.
 
LIMITATIONS
 
     No Fund will enter into any financial futures contract or purchase any
option thereon if, immediately thereafter, the total amount of its assets
required to be on deposit as initial margin to secure its obligations under
financial futures contracts, plus the amount of premiums paid by it for
outstanding options to purchase futures contracts, exceeds 5% of the market
value of its total assets; provided however, that in the case of an option that
is in-the-money at the time of purchase, the in-the-money amount may be excluded
in calculating the 5% limitation. This is a fundamental policy of the Mid Cap
Index Fund and the Socially Responsible Fund.
 
     In addition, each Fund has an operating policy which provides that it will
not enter into financial futures contracts or write put or call options with
respect to financial futures contracts unless such transactions are either
"covered" or subject to segregation requirements considered appropriate by the
SEC staff. Further, each Fund has an operating policy which provides that it
will not enter into custodial arrangements with respect to initial or variation
margin deposits or marked-to-market amounts unless the custody of such initial
and variation margin deposits and marked-to-market amounts are in compliance
with current SEC staff interpretive positions or no-action letters or rules
adopted by the SEC.
 
SHORT SALES AND SHORT SALES AGAINST THE BOX
 
     Certain Funds may engage in short sale transactions in securities listed on
one or more national securities exchanges or on the National Association of
Securities Dealers, Inc. Automated Quotation System ("NASDAQ"). Short selling
involves the sale of borrowed securities. At the time a short sale is effected,
a Fund incurs an obligation to replace the security borrowed at whatever its
price may be at the time that the Fund purchases it for delivery to the lender.
When a short sale transaction is closed out by delivery of the securities, any
gain or loss on the transaction is taxable as a short term capital gain or loss.
Until the security is replaced, the Fund is required to pay to the lender
amounts equal to any dividends or interest which accrue during the period of the
loan. All short sales will be fully collateralized. A Fund may also engage in
short sales against the box, which involves selling a security the Fund holds in
its portfolio for delivery at a specified date in the future. A Fund will not
engage in short sales or short sales against the box if immediately following
such transaction the aggregate market value of all securities sold short and
sold short against the box would exceed 10% of the Fund's net assets (taken at
market value).
 
MONEY MARKET SECURITIES OF FOREIGN ISSUERS
 
     Foreign money market instruments utilized by the Funds will be limited to:
(i) obligations of, or
 
                                       42
<PAGE>   105
 
guaranteed by, a foreign government, its agencies or instrumentalities; (ii)
certificates of deposit, bankers' acceptances, short-term notes, negotiable time
deposits and other obligations of the ten largest banks in each foreign country,
measured in terms of net assets; and (iii) other short-term unsecured corporate
obligations (usually 1 to 270 day commercial paper) of foreign companies. For
temporary purposes or in light of adverse foreign political or economic
conditions, the Funds may invest in short-term high quality foreign money market
securities without limitation.
 
                               INVESTMENT ADVISER
 
     VALIC is a stock life insurance company organized on May 1, 1969 under the
Texas Insurance Code as a successor to The Variable Annuity Life Insurance
Company of America, a District of Columbia insurance company organized in 1955.
VALIC's sole business consists of offering fixed and variable (and combinations
thereof) retirement annuity contracts. VALIC is an indirect wholly-owned
subsidiary of American General Corporation, Houston, Texas. Members of the
American General Corporation group of companies operate in each of the 50
states, the District of Columbia, and Canada and collectively engage in
substantially all forms of financial services, with activities heavily weighted
toward insurance. American General Corporation was incorporated as a Texas
business corporation on February 26, 1980 as the successor to American General
Life Insurance Company (organized in 1926) as the result of a corporate
reorganization completed on July 1, 1980.
 
     VALIC serves as the investment adviser to each of the Funds pursuant to an
Investment Advisory Agreement with each fund dated [            , 1998], that
was approved by the Board of Trustees on [            , 1998]. Under the
Investment Advisory Agreement, each Fund pays VALIC an annual fee, payable
monthly, based on its average daily net asset value.
 
     Pursuant to the Investment Advisory Agreement, the Series Company retains
VALIC to manage the investment of the assets of each Fund, maintain a trading
desk, and place orders for the purchase and sale of portfolio securities. As
investment adviser, VALIC obtains and evaluates as appropriate economic,
statistical, and financial information in order to formulate and implement
investment programs in furtherance of each Fund's investment objective(s) and
investment program. Pursuant to the Investment Advisory Agreements, VALIC
provides other services including furnishing the services of the President and
such other executives and clerical personnel as the Series Company requires to
conduct its day-to-day operations, to prepare the various reports and statements
required by law, and to conduct any other recurring or nonrecurring activity
which the Series Company may need to continue operations. The Investment
Advisory Agreement provides that the Series Company pay all expenses not
specifically assumed by VALIC under the Agreement. Examples of the expenses paid
by the Series Company include transfer agency fees, custodial fees, the fees of
outside legal and auditing firms, the costs of reports to shareholders, expenses
of servicing shareholder accounts (e.g., daily calculation of the net asset
value).
 
     The Investment Advisory Agreement requires that VALIC's advisory fee be
reduced by any commissions, tender and exchange offer solicitation fees and
other fees, or similar payments (less any direct expenses incurred) received by
VALIC or its affiliates in connection with the purchase and sale of portfolio
investments of the Funds. In this regard, the Investment Advisory Agreements
require VALIC to use its best efforts to recapture tender and exchange
solicitation offer fees for each Fund's benefits, and to advise the Series
Company's Board of Trustees of any other fees, or similar payments that it (or
any of its affiliates) may receive in connection with each Fund's portfolio
transactions or of other arrangements that may benefit any of the Funds or the
Series Company.
 
     Pursuant to an Accounting Services Agreement dated [            , 1998 ]
("Agreement"), VALIC provides accounting services to the Series Company. The
Agreement provides that the Series Company will pay to VALIC an annual fee
payable monthly based on average daily net assets for providing the accounting
services.
 
     The Investment Advisory Agreement may be continued with respect to any Fund
if specifically approved at least annually by (a)(i) the Series Company's Board
of Trustees or (ii) a majority of that Fund's outstanding voting securities (as
defined by the 1940 Act), and (b) the affirmative vote of a
                                       43
<PAGE>   106
 
majority of the trustees who are not parties to the agreement or "interested
persons" of any such party (as defined by the 1940 Act) by votes cast in person
at a meeting called for this purpose. The Investment Advisory Agreement also
provides that it shall terminate automatically if assigned. The Investment
Advisory Agreement may be terminated as to any Fund at any time by the Series
Company's Board of Trustees, by vote of a majority of the Fund's outstanding
voting securities, or by VALIC, on not more than 60 days' written notice, nor
less than 30 days' written notice, or upon such shorter notice as may be
mutually agreed upon, without the payment of any penalty. Additionally the
Investment Advisory Agreement provides that VALIC shall not be liable to the
Series Company, or any shareholder in the Series Company, for any act or
omission in rendering services under the Agreement, or for any losses sustained
in the purchase, holding, or sale of any portfolio security, so long as there
has been no willful misfeasance, bad faith, negligence, or reckless disregard of
obligations or duties on the part of VALIC.
 
                            INVESTMENT SUB-ADVISERS
 
     Pursuant to Investment Sub-advisory Agreements dated [            , 1998]
with each Sub-adviser, VALIC has engaged Bankers Trust Company ("Bankers Trust")
to provide investment Sub-advisory services for the Small Cap Index Fund, the
Mid Cap Index Fund, the S&P 500 Index Fund and a portion of the Small Cap Value
Fund. In addition, Capital Guardian Trust Company ("Capital Guardian") provides
Sub-advisory services for the International Value Fund, the Domestic Bond Fund
and the Balanced Fund, Jacobs Asset Management provides Sub-advisory services
for the International Growth Fund, State Street Bank and Trust Company/State
Street Global Advisors ("State Street Global Advisors") provides Sub-advisory
services for the Large Cap Value Fund, Goldman Sachs Asset Management ("GSAM")
provides Subadvisory services for the Large Cap Growth Fund and Neuberger &
Berman Management Inc. ("N&B Management") provides Sub-advisory services for the
Mid Cap Value Fund pursuant to separate Sub-advisory Agreements. Brown Capital
Management, Inc. ("Brown Capital Management") provides Sub-advisory services for
the Mid Cap Growth Fund, Fiduciary Management Associates, Inc. ("FMA") provides
Sub-advisory services for a portion of the Small Cap Value Fund and J.P. Morgan
Investment Management, Inc. ("JP Morgan") provides Sub-advisory services for the
Small Cap Growth Fund pursuant to separate Sub-advisory Agreements, as well.
Bankers Trust, Capital Guardian, Jacobs Asset Management, State Street Global
Advisors, GSAM, N&B Management, Brown Capital Management, FMA and JP Morgan
(collectively, the "Sub-advisers") will be subject to the control, supervision
and direction of VALIC, which will retain responsibility for the overall
management of the Funds to which these companies provide Sub-advisory services
(collectively, the "Sub-advised Funds").
 
     The Series Company was issued an exemptive order by the SEC on      , 1998
for an exemption (the "Exemption") from certain provisions of the Investment
Company Act of 1940 ("1940 Act") which would otherwise require VALIC to obtain
formal shareholder approval prior to engaging and entering into sub-advisory
agreements with Sub-advisers. The relief is based on the conditions set forth in
the Exemption that, among other things; (1) VALIC will select, monitor, evaluate
and allocate assets to the Sub-advisers and oversee Sub-advisers compliance with
the relevant Fund's investment objective, policies and restrictions; (2) before
a Fund may rely on the Exemption, the Exemption must be approved by the
shareholders of the Funds operating under the Exemption; (3) the Series Company
will provide to shareholders certain information about a new Sub-adviser; (4)
the Series Company will disclose in its Prospectus the existence, substance and
effect of the Exemption; and (5) the Trustees, including a majority of the "non-
interested" Trustees, must approve each sub-advisory agreement in the manner
required under the 1940 Act. Any changes to the Investment Advisory Agreement
between the Series Company and VALIC would still require shareholder approval.
As required by the Exemption, the shareholders of each Fund determined, at a
shareholders' meeting held on      , 1998, to permit the Series Company to
replace or add Sub-advisers and to enter into sub-advisory agreements with
Sub-advisers upon approval of the Board of Trustees but without formal
shareholder approval.
 
     Pursuant to the Investment Sub-advisory Agreements and subject to VALIC's
control, super-
                                       44

vision and direction, the Sub-advisers will manage
the investment and reinvestment of the assets of the Sub-advised Funds,
including the evaluation of pertinent economic, statistical, financial and other
data, and the determination of industries and companies to be represented in the
Sub-advised Funds. Further, the Sub-advisers will maintain a trading desk and
place orders for the purchase and sale of portfolio investments for the
Sub-advised Funds, accounts with brokers and dealers selected by the
Sub-advisers, or arrange for any other entity to provide a trading desk and to
place orders with brokers and dealers selected by the Sub-advisers and VALIC.
 
     The Investment Sub-advisory Agreements provide that the Sub-advisers will
bear the expense of discharging their responsibilities.

a monthly fee computed at the annual rate of 0.25% of average daily net asset
values of the Large Cap Value Fund, but in no event less than $50,000 per year.
 
     The Investment Sub-advisory Agreements require that each Sub-adviser
promptly reduce its monthly fee by the amount of any commission, tender and
exchange offer solicitation fees, other fees or similar payments received by the
Sub-adviser, or any affiliated person of the Sub-adviser, in connection with
Sub-advised Fund portfolio transactions. Such "commissions" or "other fees"
exclude those charged by brokers or dealers affiliated with a Sub-adviser, as
referred to below. Such "tender and exchange offer solicitation fees" exclude
those received by a Sub-adviser acting in the capacity of manager for any such
offer. In this regard, the Sub-advisory Agreements require the Sub-advisers to
use their best efforts to obtain tender and exchange solicitation offer fees for
each Fund's benefit, and to advise VALIC of any other fees or similar payments
that they (or any of their affiliates) may receive in connection with any Fund's
portfolio transactions or of other arrangements that may benefit any of the
Funds.
 
     The Investment Sub-advisory Agreements may be continued with respect to any
of the Funds if approved at least annually by the vote of the Series Company's
Board of Trustees who are not parties to the Investment Sub-advisory Agreements
or interested persons of any such parties, cast in person at a meeting called
for the purpose of voting on such approval and by a vote of a majority of the
Series Company's Board of Trustees or a majority of the relevant Fund's
outstanding voting securities.
 
     Subject to the Exemption, the Investment Sub-advisory Agreements may be
terminated at any time by VALIC, the relevant Sub-adviser, the Series Company's
Board of Trustees, or by vote of a majority of the outstanding voting securities
of the relevant Sub-advised Fund, on not more than 60 days' nor less than 30
days' written notice to the other entities, or upon such shorter notice as may
be mutually agreed upon. Such termination shall be without the payment of any
penalty.
 
     The Investment Sub-advisory Agreements provide that the Sub-advisers shall
not be liable to VALIC, the Series Company or to any shareholder of the Series
Company for any act or omission in rendering services under the Investment
Sub-advisory Agreements or for any losses sustained in the purchase, holding or
sale of any portfolio security, so long as there has been no willful
misfeasance, bad faith, negligence or reckless disregard of obligations or
duties on the part of the Sub-advisers.
 
                      PORTFOLIO TRANSACTIONS AND BROKERAGE
 
     As investment adviser to the Series Company, VALIC has responsibility for
placing (and deciding when to place) orders for the purchase and sale of
investments for the portfolio of each Fund, selecting brokers or dealers to
handle these transactions, and negotiating commissions on these transactions.
VALIC utilizes the assistance of Sub-advisers in selecting brokers or dealers to
handle transactions for the Sub-advised Funds. The Sub-advisers may employ
affiliated brokers for portfolio transactions under circumstances described in
the Prospectus under the heading "Investment Management."
 
     Virtually all of the over-the-counter transactions by the actively managed
portion of the Small Cap Value Fund, the Mid Cap Growth Fund, are principal
transactions with issuers and dealers at net prices which entail no brokerage
commissions. The Mid Cap Index Fund, the Large Cap Growth Fund, the S&P 500
Index Fund, the Small Cap Index Fund, the International Value Fund, the Balanced
Fund, the Domestic Bond Fund, the Mid Cap Value Fund, and the Socially
Responsible Fund, each purchase and sell most of their portfolio securities on a
national securities exchange on an agency basis. The International Growth Fund,
the Mid Cap Growth Fund, the Small Cap Value Fund, and the Large Cap Value Fund
engage in over-the-counter transactions with principals and transactions with
national securities exchanges on an agency basis. The Series Company normally
enters into principal
 
                                       46
<PAGE>   109
 
transactions directly with the issuer or the market-maker.
 
     When the Series Company purchases or sells securities or financial futures
contracts on an exchange, it pays a commission to any FCM or broker executing
the transaction. When the Series Company purchases securities from the issuer,
an underwriter usually receives a commission or "concession" paid by the issuer.
When the Series Company purchases securities from a market-maker, it pays no
commission, but the price includes a "spread" or "mark-up" (between the bid and
asked price) earned by the market-making dealer on the transaction.
 
     In purchasing and selling each Fund's portfolio securities, it is the
policy of VALIC and the Sub-advisers (collectively, the "Advisers") to seek the
best execution at the most favorable price through responsible broker-dealers
and, in the case of agency transactions, at competitive commission rates. When
selecting brokers or dealers, and in negotiating prices and commissions, the
Advisers consider such factors as: the broker or dealer's reliability; the
quality of the broker or dealer's execution services on a continuing basis; the
rate of the commission; the size and difficulty of the order and the timeliness
of execution; the reliability, integrity, financial condition, general
execution, and operational capabilities of that firm and competing
broker-dealers. In over-the-counter transactions, the Advisers place orders
directly with the principal market-maker unless they believe the Series Company
can obtain a better price (or receive better execution of orders) from a broker
on an agency basis. In transactions executed on securities or commodities
exchanges, the Advisers seek the best overall price and execution at the most
favorable commission rate (except when higher brokerage commissions are paid to
obtain brokerage and research services, as explained below). When the Advisers
believe that more than one firm meets these criteria the Advisers may prefer
brokers who provide the Advisers or the Series Company with brokerage and
research services, described below.
 
     The Advisers may cause a Fund to pay a broker-dealer a commission (for
executing a securities transaction) that is greater than the commission another
broker-dealer would have received for executing the same transaction, if the
Advisers determine in good faith that the greater commission paid to the first
broker-dealer is reasonable in relation to the value of brokerage and research
services provided to the Advisers viewed in terms of either that particular
transaction or the overall responsibilities of the Advisers.
 
     The Advisers receive a wide range of research services from broker-dealers,
including: information on securities markets, the economy and individual
companies; statistical information; accounting and tax law interpretations;
technical market action; pricing and appraisal services; and credit analyses.
Research services are received by the Advisers primarily in the form of written
reports, telephone contacts, personal meetings with securities analysts,
corporate and industry spokespersons, and access to various computer-generated
data.
 
     The Advisers have no agreements or understandings with broker-dealers by
which specific amounts of transactions or commissions are directed to specific
broker-dealers.
 
     The Advisers evaluate whether such research services provide lawful and
appropriate assistance to them in the performance of their investment
decision-making responsibilities, for the Series Company. The Advisers will not
cause the Series Company to pay higher commissions without first determining, in
good faith, that the cost is reasonable considering the brokerage and research
services provided, with respect to either the particular transaction or the
Advisers' overall responsibilities with respect to accounts for which they
exercise investment discretion. The Advisers receive research services at no
cost and cannot assign any specific monetary value to them; nevertheless, the
Advisers believe these supplemental investment research services are essential
to the Advisers' ability to provide high quality portfolio management to the
Funds. Research services furnished by broker-dealers through whom a Fund effects
securities transactions may be used by the Advisers in servicing all of the
Funds, and the Advisers may not use all such services in managing the Funds.
 
     The amount of brokerage commissions paid, the quality of execution, the
nature and quality of research services provided, and the amount of commissions
paid to firms providing research services are reviewed quarterly by the Series
Company's Board of Trustees.
 
     Occasions may arise when one or more of the Funds or other accounts that
may be considered affiliated persons of the Funds under the 1940 Act
 
                                       47
<PAGE>   110
 
desire to purchase or sell the same portfolio security at approximately the same
time. On those occasions when such simultaneous purchase and sale transactions
are made such transaction will be allocated in an equitable manner according to
written procedures approved by the Series Company's Board of Trustees.
Specifically, such written procedures provide that in allocating purchase and
sale transactions made on a combined basis the parties will seek to achieve the
same net unit price of securities for each Fund or other account and to allocate
as nearly as practicable, such transactions on a pro-rata basis substantially in
proportion to the amounts ordered to be purchased and sold by each Fund or other
account. In some cases, this procedure could have an adverse effect on the price
or quantity of securities available to the Funds. However, the Funds may,
alternatively, benefit from lower broker's commissions and/or correspondingly
lower costs for brokerage and research services by engaging in such combined
transactions. In the Advisers' opinion, the results of this procedure will, on
the whole, be in the best interest of each Fund.
 
               OFFERING, PURCHASE, AND REDEMPTION OF FUND SHARES
 
     Pursuant to a distribution agreement, The Variable Annuity Marketing
Company ("VAMCO") acts without remuneration as the Series Company's agent in the
distribution of Fund Shares to registered and unregistered separate accounts of
VALIC and its affiliate's. VAMCO's address is the same as that of VALIC.
 
     The distribution agreement between VAMCO and the Series Company provides
that it shall continue in force from year to year, provided that such
continuance is approved at least annually (a)(i) by the Board of Trustees of the
Series Company, or (ii) by vote of a majority of the Series Company's
outstanding voting securities (as defined in the 1940 Act) and (b) by the
affirmative vote of a majority of the Series Company's Trustees who are not
'interested persons' (as defined in the 1940 Act) of the Series Company by votes
cast in person at a meeting called for such purpose. The distribution agreement
may be terminated at any time, without penalty, by a vote of the Board of
Trustees of the Series Company or by a vote of a majority of the outstanding
voting securities of the Series Company, or by VAMCO, on sixty days' written
notice to the other party. The distribution agreement also automatically
terminates in the event of an assignment.
 
     Pursuant to the distribution agreement VAMCO pays promotional and
advertising expenses and the cost of printing prospectuses used to offer and
sell shares of the Series Company (after typesetting and printing the copies
required for regulatory filings by the Series Company). Promotional and
advertising expenses include any expense related to distribution of shares of
the Funds or attributable to any activity primarily intended to result in the
sale of shares, including, for example, the preparation, printing, and
distribution of advertising and sales literature (including reports to
shareholders used as sales literature). VALIC reimburses VAMCO for these
expenses. Thus all such expenses incurred by VAMCO are passed directly on to
VALIC, its parent. The Series Company pays all expenses related to the
registration of Fund shares under federal and state laws, including registration
and filing fees, the cost of preparing the prospectus for such purpose, and
related expenses of outside legal and auditing firms.
 
     As explained in the prospectus for the Contracts, payments of surrender
values, as well as lump sum payments available under the annuity options of the
Contracts, may be suspended or postponed at any time when redemption of shares
is suspended. Normally, the Series Company redeems Fund shares within seven days
of receipt of request therefor, but may postpone redemptions beyond seven days
when: (1) the New York Stock Exchange is closed for other than weekends and
customary holidays, or trading on the New York Stock Exchange becomes
restricted; (2) an emergency exists making disposal or valuation of a Fund's
assets not reasonably practicable; or (3) the SEC has so permitted by order for
the protection of the Series Company's shareholders.
 
     The Series Company normally redeems Fund shares for cash. Although the
Series Company, with respect to each Fund, may make full or partial payment by
assigning to investors, Series Company portfolio securities at their value used
in determining the redemption price (i.e. by redemption-in-kind), the Series
Company, pursuant to Rule 18f-1 under the 1940 Act, has filed a notification of
election on Form 18f-1. Pursuant to this election, the Series Company has
committed
                                       48
<PAGE>   111
 
itself to pay investors, in cash, all redemptions made during any 90 day period,
up to the lesser of $250,000 or 1% of the Series Company's net asset value. The
securities to be paid in-kind to an investor will be selected in such manner as
the Board of Trustees deems fair and equitable. In such cases, investors would
incur brokerage expenses should they wish to liquidate these portfolio
securities.
 
   
     All shares are offered for sale and redeemed at net asset value. Net asset
value per share is determined by dividing the net assets of a Fund by the number
of that Fund's outstanding shares at such time.
    
   
    
 
                        DETERMINATION OF NET ASSET VALUE
 
     Equity investments (including common stocks, preferred stocks, convertible
securities, and warrants) and call options written on all portfolio investments
listed or traded on a national exchange are valued at their last sale price on
that exchange prior to the time when assets are valued. In the absence of any
exchange sales on that day and for unlisted equity securities, such securities
and call options written on portfolio securities are valued at the last sale
price on the NASDAQ (National Association of Securities Dealers Automated
Quotations) National Market System. In the absence of any National Market System
sales on that day, equity securities are valued at the last reported bid price
and call options written on all portfolio securities for which other
over-the-counter market quotations are readily available are valued at the last
reported asked price.
 
     U.S. Treasury securities and other obligations issued or guaranteed by the
U.S. government, its agencies or instrumentalities, are valued at representative
quoted prices. Such quotations generally are obtained from government securities
pricing services; however, in circumstances where it is deemed appropriate to do
so, quotations may be obtained from dealers in government securities.
 
     Publicly-traded corporate bonds are valued at prices obtained from State
Street Bank and Trust Series Company.
 
     Short-term debt securities for which market quotations are readily
available are valued at the last reported bid price, except for those with a
remaining maturity of 60 days or less which are valued by the amortized cost
method (unless, due to special circumstances, the use of such a method with
respect to any security would result in a valuation which does not approximate
fair market value).
 
     Convertible bonds are valued at prices obtained from one or more of the
major dealers in such bonds. Where there is a discrepancy between dealers or
when no quotes are readily available, values may be adjusted based on a
combination of yields and premium spreads to the underlying common stock.
 
     Portfolio securities that are primarily traded on foreign securities
exchanges are generally valued at the last sale price on the exchange where such
security is primarily traded. All foreign securities traded on the
over-the-counter market are valued at the last sale quote, if market quotations
are available, or the last closing bid price, if there is no active trading in a
particular security for a given day. Where market quotations are not readily
available for such foreign over-the-counter securities, then such securities
will be valued in good faith by a method that the Series Company's Board of
Trustees, or its delegates, believes accurately reflects fair value. Quotations
of foreign securities in foreign currencies are converted, at current exchange
rates, to their U.S. dollar equivalents in order to determine their current
value. In addition, because of the need to value foreign securities (other than
ADRs) as of the close of trading on various exchanges and over-the-counter
markets throughout the world, the calculation of the net asset value of Funds
investing in such foreign securities may not take place contemporaneously with
the valuation of such foreign securities in those Funds' portfolios.
 
     Options purchased by the Funds (including options on financial futures
contracts, stock indices, foreign currencies, and securities) listed on national
securities exchanges are valued on the exchange where such security is primarily
traded.
 
     Over-the-counter options purchased or sold by the Funds are valued based
upon prices provided by market-makers in such securities or dealers in such
currencies.
 
     Exchange-traded financial futures contracts (including interest rate
futures contracts, stock index futures contracts, and currency futures con-
 
                                       49

tracts) are valued at the settlement price for such contracts established each
day by the board of trade or exchange on which such contracts are traded.
Unlisted financial futures contracts are valued based upon prices provided by
market-makers in such financial futures contracts.
 
     All of the assets of the Money Market Fund are valued on the basis of
amortized cost. Under the amortized cost method of valuation, securities are
valued at a price on a given date, and thereafter a constant accretion of any
discount or amortization of any premium to maturity is assumed, 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 a
Fund would receive if it sold the security. During such periods, the yield to
investors may differ somewhat from that obtained by a similar fund or portfolio
which uses available market quotations to value all of its portfolio securities.
The Series Company's Board of Trustees has established procedures reasonably
designed, taking into account current market conditions and Money Market Fund'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 Board, at
such intervals as it deems appropriate, to determine the extent, if any, to
which the net asset value per share calculated by using available market
quotations deviates from $1.00 per share. In the event such deviation should
exceed one half of one percent, the Board will promptly consider initiating
corrective action. If the Board believes 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; shortening the average maturity of the portfolio; withholding
or reducing dividends; or utilizing a net asset value per share determined from
available market quotations. Even if these steps were taken, the Money Market
Fund's net asset value might still decline.
 
                 CALCULATION OF YIELD FOR THE MONEY MARKET FUND
 
     The yield of the Money Market Fund is its net income expressed as a
percentage of assets on an annualized basis for a seven day period. Rule 482
under the 1933 Act requires that a yield quotation set forth in an advertisement
for a money market fund be computed by a standardized method based on an
historical seven calendar day period. The current yield is computed by
determining the net change (exclusive of realized gains and losses from the sale
of securities and unrealized appreciation and depreciation) in the value of a
hypothetical pre-existing account having a balance of one share at the beginning
of the period, and then 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. The base period return is then multiplied by (365/7) to annualize the
yield figure. 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
any fees that are charged to all shareholder accounts, in proportion to the
length of the base period and the Money Market Fund's average account size. The
Money Market Fund may also calculate its compound effective yield by compounding
the unannualized base period return (calculated as described above) by adding
one to the base period return, raising the sum to a power equal to 365 divided
by 7, and subtracting one.
 
     The yield quoted by the Money Market Fund 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 Money Market Fund's portfolio, their quality and
length of maturity, and the Money Market Fund's operating expenses. The length
of maturity for the portfolio is the average dollar weighted maturity of the
portfolio. In other words, the portfolio has an average maturity for all of its
issues, stated in numbers of days and weighted according to the relative value
of each investment.
 
     The yield fluctuates daily as the income earned on the investments of the
Money Market Fund fluctuates. Accordingly, neither the Series Company nor VALIC
can assure the yield quoted on any given occasion will remain constant for any
period of time. For example, the Money Market Fund's
 
                                       50
<PAGE>   113
 
yield will change if it experiences a net inflow of new assets which it then
invests in securities whose yield is higher or lower than that being currently
earned on investments. Investments in the Money Market Fund are not insured and
investors comparing results of the Money Market Fund with investment results and
yields from other sources such as banks or savings and loan associations should
understand this distinction. In addition, other money market funds as well as
banks and savings and loan associations may calculate their yields on a
different basis and the yield quoted by the Money Market Fund from time-to-time
could vary upwards or downwards if another method of calculation or base period
were used.
 
                                    TAXATION
 
     The following is a summary of the principal U.S. federal income, and
certain state and local, tax considerations regarding the purchase, ownership
and disposition of shares in each Fund of the Series Company. This summary does
not address special tax rules applicable to certain classes of investors, such
as tax-exempt entities, insurance companies and financial institutions. Each
prospective shareholder is urged to consult his own tax adviser with respect to
the specific federal, state, local and foreign tax consequences of investing in
each Fund. The summary is based on the laws in effect on the date of this
Statement of Additional Information, which are subject to change.
 
GENERAL
 
     Each Fund is a separate taxable entity. Each Fund has elected to be treated
and intends to qualify for each taxable year as a regulated investment company
under Subchapter M of the Code.
 
     Qualification as a regulated investment company under the Code requires,
among other things, that (a) a Fund derives at least 90% of its gross income for
its taxable year from dividends, interest, payments with respect to securities
loans and gains from the sale or other disposition of stocks or securities or
foreign currencies, or other income (including but not limited to gains from
options, futures, and forward contracts) derived with respect to its business of
investing in such stock, securities or currencies (the "90% gross income test");
and (b) such Fund diversify its holdings so that, at the close of each quarter
of its taxable year, (i) at least 50% of the market value of such Fund's total
(gross) assets is comprised of cash, cash items, U.S. Government securities,
securities of other regulated investment companies and other securities limited
in respect of any one issuer to an amount not greater in value than 5% of the
value of such Fund's total assets and to not more than 10% of the outstanding
voting securities of such issuer, and (ii) not more than 25% of the value of its
total (gross) assets is invested in the securities of any one issuer (other than
U.S. Government securities and securities of other regulated investment
companies) or two or more issuers controlled by the Fund and engaged in the
same, similar or related trades or businesses. For purposes of the 90% gross
income test, income that a Fund earns from equity interests in certain entities
that are not treated as corporations (e.g., partnerships or trusts) for U.S. tax
purposes will generally have the same character for such Fund as in the hands of
such an entity; consequently, a Fund may be required to limit its equity
investments in such entities that earn fee income, rental income, or other
nonqualifying income. In addition, future Treasury regulations could provide
that qualifying income under the 90% gross income test will not include gains
from foreign currency transactions that are not directly related to a Fund's
principal business of investing in stock or securities or options and futures
with respect to stock or securities. Using foreign currency positions or
entering into foreign currency options, futures and forward or swap contracts
for purposes other than hedging currency risk with respect to securities in a
Fund's portfolio or anticipated to be acquired may not qualify as
"directly-related" under these tests.
 
     If a Fund complies with such provisions, then in any taxable year in which
such Fund distributes, in compliance with the Code's timing and other
requirements, at least 90% of its "investment company taxable income" (which
includes dividends, taxable interest, taxable accrued original issue discount
and market discount income, income from securities lending, any net short-term
capital gain in excess of net long-term capital loss, certain net realized
foreign exchange gains and any other taxable income other than "net capital
gain," as defined below, and is reduced by deductible expenses), and at least
90% of the excess of its gross tax-exempt interest income (if any) over certain
disallowed
                                       51
<PAGE>   114
 
deductions, such Fund (but not its shareholders) will be relieved of federal
income tax on any income of the Fund, including long-term capital gains,
distributed to shareholders. However, if a Fund retains any investment company
taxable income or "net capital gain" (the excess of net long-term capital gain
over net short-term capital loss), it will be subject to a tax at regular
corporate rates on the amount retained. If the Fund retains any net capital
gain, the Fund may designate the retained amount as undistributed capital gains
in a notice to its shareholders who, if subject to U.S. federal income tax on
long-term capital gains, (i) will be required to include in income for federal
income tax purposes, as long-term capital gain, their shares of such
undistributed amount, and (ii) will be entitled to credit their proportionate
shares of the tax paid by the Fund against their U.S. federal income tax
liabilities, if any, and to claim refunds to the extent the credit exceeds such
liabilities. For U.S. federal income tax purposes, the tax basis of shares owned
by a shareholder of the Fund will be increased by an amount equal under current
law to 65% of the amount of undistributed net capital gain included in the
shareholder's gross income. Each Fund intends to distribute for each taxable
year to its shareholders all or substantially all of its investment company
taxable income, net capital gain and any net tax-exempt interest. Exchange
control or other foreign laws, regulations or practices may restrict
repatriation of investment income, capital or the proceeds of securities sales
by foreign investors and may therefore make it more difficult for certain Funds
to satisfy the distribution requirements described above, as well as the excise
tax distribution requirements described below. However, each Fund generally
expects to be able to obtain sufficient cash to satisfy such requirements from
new investors, the sale of securities or other sources. If for any taxable year
a Fund does not qualify as a regulated investment company, it will be taxable on
all of its investment company taxable income and net capital gain at corporate
rates, and its distributions to shareholders will be taxable as ordinary
dividends to the extent of its current and accumulated earnings and profits.
 
     In order to avoid a 4% federal excise tax, each Fund must distribute (or be
deemed to have distributed) by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
capital gains over its capital losses (generally computed on the basis of the
one-year period ending on October 31 of such year), and all taxable ordinary
income and the excess of capital gains over capital losses for the previous year
that were not distributed for such year and on which the Fund paid no federal
income tax. For federal income tax purposes, dividends declared by a Fund in
October, November or December to shareholders of record on a specified date in
such a month and paid during January of the following year are taxable to such
shareholders as if received on December 31 of the year declared. The Funds
anticipate that they will generally make timely distributions of income and
capital gains in compliance with these requirements so that they will generally
not be required to pay the excise tax. For federal income tax purposes, each
Fund is permitted to carry forward a net capital loss in any year to offset its
own capital gains, if any, during the eight years following the year of the
loss.
 
     Gains and losses on the sale, lapse, or other termination of options and
futures contracts, options thereon and certain forward contracts (except certain
foreign currency options, forward contracts and futures contracts) will
generally be treated as capital gains and losses. Certain of the futures
contracts, forward contracts and options held by a Fund will be required to be
"marked-to-market" for federal income tax purposes, that is, treated as having
been sold at their fair market value on the last day of the Fund's taxable year.
These provisions may require a Fund to recognize income or gains without a
concurrent receipt of cash. Any gain or loss recognized on actual or deemed
sales of these futures contracts, forward contracts, or options will (except for
certain foreign currency options, forward contracts, and futures contracts) be
treated as 60% long-term capital gain or loss and 40% short-term capital gain or
loss. As a result of certain hedging transactions entered into by a Fund, the
Fund may be required to defer the recognition of losses on futures contracts,
forward contracts, and options or underlying securities or foreign currencies to
the extent of any unrecognized gains on related positions held by such Fund and
the characterization of gains or losses as long-term or short-term may be
changed. The tax provisions described above applicable to options, futures and
forward contracts may affect the amount, timing and character of a Fund's
distributions to shareholders. Application of certain requirements for
qualification as a regulated investment company and/or these tax rules to
certain investment practices, such as dollar rolls, or certain deriv-
 
                                       52
<PAGE>   115
 
atives such as interest rate swaps, floors, caps and collars and currency,
mortgage or index swaps may be unclear in some respects, and a Fund may
therefore be required to limit its participation in such transactions. Certain
tax elections may be available to a Fund to mitigate some of the unfavorable
consequences described in this paragraph.
 
     Section 988 of the Code contains special tax rules applicable to certain
foreign currency transactions and instruments that may affect the amount, timing
and character of income, gain or loss recognized by a Fund. Under these rules,
foreign exchange gain or loss realized with respect to foreign currencies and
certain futures and options thereon, foreign currency-denominated debt
instruments, foreign currency forward contracts, and foreign
currency-denominated payables and receivables will generally be treated as
ordinary income or loss, although in some cases elections may be available that
would alter this treatment. If a net foreign exchange loss treated as ordinary
loss under Section 988 of the Code were to exceed a Fund's investment company
taxable income (computed without regard to such loss) for a taxable year, the
resulting loss would not be deductible by the Fund or its shareholders in future
years. Net loss, if any, from certain foreign currency transactions or
instruments would exceed net investment income otherwise calculated for
accounting purposes with the result being either no dividends being paid or a
portion of a Fund's dividends being treated as a return of capital for tax
purposes, nontaxable to the extent of a shareholder's tax basis in his shares
and, once such basis is exhausted, generally giving rise to capital gains.
 
     A Fund's investment in zero coupon securities, deferred interest
securities, certain structured securities or other securities bearing original
issue discount or, if a Fund elects to include market discount in income
currently, market discount, as well as any "mark-to-market" gain from certain
options, futures or forward contracts, as described above, will generally cause
it to realize income or gain prior to the receipt of cash payments with respect
to these securities or contracts. In order to obtain cash to enable it to
distribute this income or gain, maintain its qualification as a regulated
investment company and avoid federal income or excise taxes, the Fund may be
required to liquidate portfolio securities that it might otherwise have
continued to hold.
 
     Certain Funds may be subject to foreign taxes on income (possibly
including, in some cases, capital gains) from foreign securities. Tax
conventions between certain countries and the U.S. may reduce or eliminate such
taxes in some cases. If, as may occur for certain Funds, more than 50% of a
Fund's total assets at the close of any taxable year consists of stock or
securities of foreign corporations, the Fund may file an election with the
Internal Revenue Service pursuant to which shareholders of the Fund would be
required to (i) include in ordinary gross income (in addition to taxable
dividends actually received) their pro rata shares of foreign income taxes paid
by the Fund that are treated as income taxes under U.S. tax regulations (which
excludes, for example, stamp taxes, securities transaction taxes, and similar
taxes) even though not actually received by such shareholders, and (ii) treat
such respective pro rata portions as foreign income taxes paid by them.
 
     If a Fund makes this election, its respective shareholders may then deduct
such pro rata portions of qualified foreign taxes in computing their taxable
incomes, or, alternatively, use them as foreign tax credits, subject to
applicable limitations, against their U.S. federal income taxes. Shareholders
who do not itemize deductions for federal income tax purposes will not, however,
be able to deduct their pro rata portion of foreign taxes paid by a Fund,
although such shareholders will be required to include their shares of such
taxes in gross income if the election is made.
 
     If a shareholder chooses to take credit for the foreign taxes deemed paid
by such shareholder as a result of any such election by a Fund, the amount of
the credit that may be claimed in any year may not exceed the same proportion of
the U.S. tax against which such credit is taken which the shareholder's taxable
income from foreign sources (but not in excess of the shareholder's entire
taxable income) bears to his entire taxable income. For this purpose,
distributions from long-term and short-term capital gains or foreign currency
gains by a Fund will generally not be treated as income from foreign sources.
This foreign tax credit limitation may also be applied separately to certain
specific categories of foreign-source income and the related foreign taxes. As a
result of these rules, which have different effects depending upon each
shareholder's particular tax situation, certain shareholders of a Fund which has
made this election may not be able to claim a credit for the full amount of
their propor-
 
                                       53
<PAGE>   116
 
tionate share of the foreign taxes paid by such Fund even if the election is
made by such a Fund.
 
     Shareholders who are not liable for U.S. federal income taxes, including
tax-exempt shareholders, will ordinarily not benefit from this election. Each
year, if any, that a Fund files the election described above, its shareholders
will be notified of the amount of (i) each Shareholder's pro rata share of
qualified foreign taxes paid by a Fund and (ii) the portion of Fund dividends
which represents income from each foreign country. The other Funds will not be
entitled to elect to pass foreign taxes and associated credits or deductions
through to their shareholders because they will not satisfy the 50% requirement
described above. If a Fund cannot or does not make this election, it may deduct
such taxes in computing the amount it is required to distribute.
 
     If a Fund acquires stock (including, under proposed regulations, an option
to acquired stock such as is inherent in a convertible bond) in certain foreign
corporations that receive at least 75% of their annual gross income from passive
sources (such as interest, dividends, rents, royalties or capital gain) or hold
at least 50% of their assets in investments producing such passive income
("passive foreign investment companies"), the Fund could be subject to federal
income tax and additional interest charges on "excess distributions" received
from such companies or gain from the sale of stock in such companies, even if
all income or gain actually received by the Fund is timely distributed to its
shareholders. The Fund would not be able to pass through to its shareholders any
credit or deduction for such a tax. In some cases, elections may be available
that would ameliorate these adverse tax consequences, but such elections would
require the Fund to include certain amounts as income or gain (subject to the
distribution requirements described above) without a concurrent receipt of cash.
Each Fund may limit and/or manage its holdings in passive foreign investment
companies to minimize its tax liability or maximize its return from these
investments.
 
     Investments in lower-rated securities may present special tax issues for a
Fund to the extent actual or anticipated defaults may be more likely with
respect to such securities. Tax rules are not entirely clear about issues such
as when a Fund may cease to accrue interest, original issue discount, or market
discount; when and to what extent deductions may be taken for bad debts or
worthless securities; how payments received on obligations in default should be
allocated between principal and income; and whether exchanges of debt
obligations in a workout context are taxable. These and other issues will be
addressed by a Fund, in the event it invests in such securities, in order to
seek to eliminate or minimize any adverse tax consequences.
 
SECTION 817(h) OF THE CODE
 
     Each of the Funds intends to comply with Section 817(h) of Code and the
regulations issued thereunder. Section 817(h) of the Code and Treasury
Department regulations thereunder impose certain diversification requirements on
variable annuity contracts based upon segregated asset accounts. These
requirements are in addition to the diversification requirements of Subchapter M
and the 1940 Act and may affect the securities in which a Fund may invest.
Failure to meet the requirements of Section 817(h) could result in immediate
taxation of the Contract owner to the extent of appreciation on investment under
the Contract.
 
     The Section 817(h) diversification requirements do not apply to pension
plan contracts. "Pension plan contracts" for these purposes generally means
authority contracts issued with respect to plans qualified under Section 401(a)
or 403(a) of the Code, Section 403(b) annuities, Individual Retirement Accounts,
Individual Retirement Annuities and annuities issued with respect to Section 457
plans.
 
     The Secretary of the Treasury may, in the future, issue additional
regulations that will prescribe the circumstances in which a Contract Owner's
control of the investments of the separate accounts investing in the Series
Company may cause the Contract Owner, rather than VALIC, to be treated as the
owner of the assets of that separate account.
 
     In order to comply with the requirements of Section 817(h) and the
regulations thereunder, the Series Company may find it necessary to take action
to ensure that a Series Contract funded by the Series Company continues to
qualify as such under federal tax laws. The Series Company, for example, may be
required to alter the investment objectives of a Fund or Funds, or substitute
the shares of one fund for those of another. No such change of investment
objectives or substitution of securities will take place without notice to the
shareholders of
 
                                       54
<PAGE>   117
 
the affected Fund, and the approval of a majority of such shareholders (as
defined in the 1940 Act) and without prior approval of the Securities and
Exchange Commission, to the extent legally required.
 
     It is not feasible to comment on all of the federal income tax consequences
concerning the Funds. Each owner of a Contract funded by the Series Company
should consult a qualified tax adviser for more complete information. The reader
should refer to the appropriate prospectus related to his or her Contracts for a
more complete description of the taxation of the separate account and of the
owner of the particular Contract.
 
                               OTHER INFORMATION
 
SHAREHOLDER REPORTS
 
     Annual Reports containing audited financial statements of the Series
Company and Semiannual Reports containing unaudited financial statements, as
well as proxy materials, are sent to Contract Owners, annuitants, or
beneficiaries as appropriate.
 
VOTING AND OTHER RIGHTS
 
     The Series Company was organized under the laws of the state of Delaware as
a business trust, and presently is authorized to sell 18 series. Each of these
series is authorized to issue an unlimited number of shares of beneficial
interest, par value $0.01 per share, divided into classes. VALIC, as the initial
sole shareholder of each of the Funds as of the commencement date of the Series
Company, controls each Fund. VALIC does not anticipate that its initial control
of each Fund will adversely effect the rights of future shareholders.
 
CUSTODY OF ASSETS
 
     Pursuant to a Custodian Contract with the Series Company, State Street Bank
and Trust Company, 225 Franklin Street, Boston, Massachusetts 02110, holds the
cash and portfolio securities of the Series Company as custodian.
 
     The Custodian is responsible for holding all securities and cash of each
Fund, receiving and paying for securities purchased, delivering against payment
securities sold, receiving and collecting income from investments, making all
payments covering expenses of the Series Company, and performing other
administrative duties, all as directed by persons authorized by the Series
Company. The Custodian does not exercise any supervisory function in such
matters as the purchase and sale of portfolio securities, payment of dividends,
or payment of expenses of the Funds or the Series Company. Portfolio securities
of the Funds purchased domestically are maintained in the custody of the
Custodian and may be entered into the book entry systems of securities
depositories approved by the Board of Trustees. Pursuant to the Custodian
Contract, portfolio securities purchased outside the United States will be
maintained in the custody of various foreign branches of the Custodian and such
other custodians, including foreign banks and foreign securities depositories,
as are approved by the Board of Trustees, in accordance with regulations under
the 1940 Act.
 
     The Custodian holds securities of the Funds on which call options have been
written and certain assets of the Funds constituting margin deposits with
respect to financial futures contracts at the disposal of the FCMs through which
such transactions are effected. The Funds may also be required to post margin
deposits with respect to covered call and put options written on stock indices
and for this purpose certain assets of those Funds may be held by the custodian
pursuant to similar arrangements with the brokers involved.
 
     This arrangement regarding margin deposits essentially consists of the
Custodian creating a separate segregated account into which it transfers (upon
the Series Company's instructions) assets from a Fund's general (regular)
custodial account. The custody agreement for such arrangement provides that FCMs
or brokers will have access to the funds in the segregated accounts when and if
the FCMs or brokers represent that the Series Company has defaulted on its
obligation to the FCMs or brokers and that the FCMs or brokers have met all the
conditions precedent to their right to receive such funds under the agreement
between the Series Company and the FCMs or brokers. The Series Company has an
agreement with each FCM or broker which provides (1) that the assets of any Fund
held by the FCM or broker will be in the possession of State Street Bank until
released or sold or otherwise disposed of in accordance with or under the terms
of such agreement, (2) that such
                                       55
<PAGE>   118
 
assets would not otherwise be pledged or encumbered by the FCM or broker, (3)
that when requested by the Series Company the FCM or broker will cause State
Street Bank to release to its general custodial account any assets to which a
Fund is entitled under the terms of such agreement, and (4) that the assets in
the segregated account shall otherwise be used only to satisfy the Series
Company's obligations to the FCM or broker under the terms of such agreement.
 
     If on any day a Fund experiences net realized or unrealized gains with
respect to financial futures contracts or covered options on stock indices held
through a given FCM or broker, it is entitled immediately to receive from the
FCM or broker, and usually will receive by the next business day, the net amount
of such gains. Thereupon, such assets will be deposited in its general or
segregated account with the Custodian, as appropriate.
 
INDEX FUNDS
 
     The Small Cap Index Fund is not promoted, sponsored or endorsed by, nor in
any way affiliated with Frank Russell Company. Frank Russell Company is not
responsible for and has not reviewed the Fund nor any associated literature or

     Frank Russell Company reserves the right, at any time and without notice,
to alter, amend, terminate or in any way change its Index(es). Frank Russell
Company has no obligation to take the needs of any particular fund or its
participants or any product or person into consideration in determining,
comprising or calculating the Index(es).
 
     Frank Russell Company's publication of the Index(es) in no way suggests or
implies an opinion by Frank Russell Company as to the attractiveness or

DESCRIPTION OF CORPORATE BOND RATINGS
 
     Moody's Investors Service, Inc.'s corporate bond ratings are as follows:
 
     Aaa -- Bonds which are rated Aaa are judged to be of the best quality and
carry the smallest degree of investment risk. Interest payments are protected by
a large or by an exceptionally stable margin, and principal is secure. While the
various protective elements are likely to change, such changes as can be
visualized are most unlikely to impair the fundamentally strong position of such
issues.
 
     Aa -- Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.
 
     A -- Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper-medium-grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment 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 payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
     Ba -- Bonds which are rated Ba are judged to have speculative elements and
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safe-guarded 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.
 
     Standard & Poor's Corporation classifications are as follows:
 
     AAA -- This is the highest rating assigned by Standard & Poor's to a
financial obligation and indicates an extremely strong capacity to meet its
financial commitment.
 
     A -- An obligation rated "A" differs from the highest rated obligations
only in small degree. The obligor's capacity to meet its financial commitment on
the obligation is strong.
 
     A -- An obligation rated "A" is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.
 
     BBB -- Obligations rated "BBB" exhibit adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.
 
     BB-B-CCC-CC -- Obligations rated "BB", "B", "CCC" and "CC" are regarded as
having significant speculative characteristics. "BB" indicates the least degree
of speculation and "CC" a higher degree of speculation. While such obligations
will likely have some quality and protective charac-
 
                                       57

teristics, they may be outweighed by large uncertainties or major exposures to
adverse conditions.
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
 
     A and Prime Commercial Paper Ratings.
 
     Commercial paper rated A by S&P has the following characteristics:
Liquidity ratios are adequate to meet cash requirements. Long-term senior debt
is rated "A" or better, although, in some cases "BBB" credits may be allowed.
The issuer has access to at least two additional channels of borrowing. Basic
earnings and cash flow have an upward trend with allowance made for unusual
circumstances. Typically, the issuer's industry is well established and the
issuer has a strong position within the industry. The reliability and quality of
management are unquestioned. The rating is described by S&P as the investment
grade category, the highest rating classification. Relative strength or weakness
of the above factors determine whether the issuer's commercial paper is rated
A-1, A-2 or A-3.
 
     Among the factors considered by Moody's in assigning commercial paper
ratings are the following: (1) evaluation of the management of the issuer; (2)
economic evaluation of the issuer's industry or industries and an appraisal of
speculative-type risks which may be inherent in certain areas; (3) evaluation of
the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten years; (7) financial strength of a parent company and the
relationships which exist with the issuer; and (8) recognition by the management
of obligations which may be present or may arise as a result of public interest
questions and preparations to meet such obligations. Relative differences in
strengths and weaknesses in respect of these criteria establish a rating in one
of three classifications. The rating Prime-1 is the highest commercial paper
rating assigned by Moody's. Its other two ratings, Prime-2 and Prime-3 are
designated Higher Quality and High Quality, respectively.

ITEM 27.  INDEMNIFICATION
 
     Reference is made to Article 8, Section 8.4 of the Registrant's Agreement
and Declaration of Trust.
 
     Article 8; Section 8.4 of the 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 of
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 willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his or her office. Absent a court determination that
an officer or trustee seeking indemnification was not liable on the merits or
guilty of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of his or her
 
                                       C-3
<PAGE>   128
 
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 willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of his or her office.
 
     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.
