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 2 (the "Series Company") was organized
as a Delaware business trust on March 16, 1998.
 
The Series Company is an open-end management investment company and currently
consists of 18 different Funds, 15 of which are 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, supervise the purchase and sale of
Fund investments and perform the cash management function. 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 employer plan that purchases shares of the Funds through
the Distributor. Most often employers establish retirement plans 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 employer's
plan materials.
 
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 employer plan,
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 or leave it in the account until you
need it. 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].
 
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.

FEE TABLE
- --------------------------------------------------------------------------------
 
FUND OPERATING EXPENSES ARE BASED ON CURRENT ESTIMATES AND ARE SUBJECT TO
MODIFICATION PRIOR TO EFFECTIVENESS.
 
The following tables illustrate the fees and expenses that investors bear
directly or indirectly as shareholders of the Funds. Shareholder transaction
expenses are the charges that an investor pays to purchase or redeem shares of a
Fund. 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.

ABOUT THE FUND'S MANAGEMENT
- --------------------------------------------------------------------------------
 
INVESTMENT ADVISER
 
VALIC, a stock life insurance company, has been in the investment advisory
business since 1960. VALIC has been the Investment Adviser for the Funds that
comprise the Series Company since their inception.
 
VALIC is a member of the American General Corporation group of companies.
Members of the American General Corporation group of companies operate in each
of the 50 states and Canada and collectively provide financial services with
activities heavily weighted toward insurance.
 
As Investment Adviser, VALIC oversees the Funds' day to day operations. Also,
VALIC supervises the purchase and sale of Fund investments and performs the cash
management function. 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. VALIC serves as Investment Adviser
through an Investment Advisory Agreement it enters into with each Fund. After
the second year, this agreement will be renewed once each year, by the Series
Company Board of Trustees.
 
One Investment Advisory Agreement dated [            , 1998] covers all 18
Funds.
 
For more information about the Advisory Agreement, see the "Investment Adviser"
section in the Statement of Additional Information.
 
INVESTMENT SUB-ADVISERS
 
For some of the Funds, VALIC works with Investment Sub-advisers, financial
service companies that specialize in certain types of investing. However, VALIC
still retains ultimate responsibility for managing the Funds. The Sub-adviser's
role is to make investment decisions for the Funds according to each Fund's
investment objectives and restrictions.
 
In selecting Sub-advisers, the Trustees carefully evaluated: (i) the nature and
quality of the services expected to be rendered to the Fund(s) by the
Sub-adviser; (ii) the distinct investment objective and policies of the Fund(s);
(iii) the history, reputation, qualification and background of the Sub-
advisers' personnel and its financial condition; (iv) its performance track
record; and (v) other factors deemed relevant. The Trustees also reviewed the
fees to be paid to each Sub-adviser.
 
The Sub-advisers are:
 
BANKERS TRUST COMPANY
("BANKER'S TRUST")
 
Bankers Trust is one of two Sub-advisers for the Small Cap Value Fund. Bankers

These financial service companies act as Investment Sub-advisers through an
agreement each entered into with VALIC. For more information on these agreements
and on these Sub-advisers, see the "Investment Sub-Advisers" section in the
Statement of Additional Information.
 
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.

The Investment Advisory Agreement we entered into with each Fund does not limit
how much the Funds pay in monthly expenses each year.
 
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.
 
From time to time VALIC, the Sub-adviser and/or the Distributor may voluntarily
undertake to reduce a Fund's expenses by reducing the fees payable to them to
the extent of, or bearing expenses in excess of, such limitations as they may
establish.
 
                                                                               7

THE SUB-ADVISERS
 
The Funds do not pay the Sub-advisers directly. According to the agreements,
VALIC pays them a fee based on the Fund's average monthly net asset values. 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 terminate,
replace or add Sub-advisers and to enter into sub-advisory agreements with Sub-
advisers upon approval of the Broad of Trustees but without formal shareholder
approval.

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 all fees if total fees are between $1.25
million and $4 million, a 7.5% discount to all fees if total fees are between $4
million and $8 million, a 10% discount to all fees if total fees are between $8
million and $12 million, and a 12.5% discount to all fees if total fees exceed
$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

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.

section in the Statement of 
Additional Information.

Under the Investment Sub-Advisory Agreement we have with State Street Global
Advisors, we pay State Street Global Advisors 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 twelve members: nine
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.
 
                                                                               9

ABOUT THE FUNDS
- --------------------------------------------------------------------------------
 
GROWTH, BALANCED, INCOME, STABILITY AND LIFESTYLE 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:
 
  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 CATEGORY
 
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.

The anticipated portfolio turnover rates for each of the Funds except the Money
Market Fund are as follows:

Moderate Growth Lifestyle         10-20%
  Fund
Conservative Growth Lifestyle     10-20%
  Fund
</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.
 
                                                                              11

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 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.

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.

  *** An "emerging country" security is issued by a
      Company that in our opinion has one or more of the following
      characteristics: (i) its principal securities trading market is in an
      emerging country; (ii) alone or on a consolidated basis, it derives 50% or
      more of its annual revenue from either goods produced, sales made or
      services performed in emerging countries, or (iii) it is organized under
      the laws of, and has a principal office in, an emerging country.
 **** Small capitalization companies are companies with
      market capitalizations of less than $1 billion at the time of purchase.
***** For temporary defensive reasons, we may invest up
      to 100% of the Fund's assets in short-term (less than twelve months to
      maturity) securities or cash, including domestic and foreign money market
      instruments, certificates of deposit, bankers' acceptances, time deposits,
      U.S. Government obligations, U.S. Government agency securities, short-term
      corporate debt securities, and commercial paper rated A-1 or A-2 by S&P or
      Prime 1 or Prime 2 by Moody's or if unrated, in our opinion of comparable
      quality. We may do this when we think economic, political or market
      conditions make it too risky for us to follow our general guidelines.

INTERNATIONAL GROWTH FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
1. The Templeton Performance Information
 
The International Growth Fund commenced operations on                and has no
investment performance record. The performance information shown below is for
the Templeton International Fund, a series of the Templeton Variable Products
Series Fund, which was managed by Mr. Jacobs, a principal of the Sub-adviser.
The Templeton International Fund has substantially similar, though not
necessarily identical objectives, policies and strategies as the International
Growth Fund. The chart below shows the historical investment performance for the
year-ended June 30, 1995 and the three-years ended 1995. The inception date for
the Templeton International Fund was May 1, 1992. During Mr. Jacobs ten years as
the portfolio manager of the fund, from May 1, 1992 to June 30, 1995, he was
primarily responsible for the day-to-day management of the fund, and no other
person had a significant role in scheduling the fund's performance.
 
Distribution and advisory fees for the International Growth Fund are higher than
the distribution and advisory fees incurred by the funds comprising the
Composite. The other fees and expenses incurred by the International Growth Fund
may be higher or lower than the other fees and expenses incurred by the funds
comprising the Composite in any given year. See "Performance and Yield
Information" in the Statement of Additional Information for a description of the
manner in which performance has been calculated. THE PERFORMANCE INFORMATION
BELOW IS BASED ON A FUND COMPARABLE TO THE INTERNATIONAL GROWTH FUND AND DOES
NOT REFLECT THE PERFORMANCE OF THE FUND ITSELF.

2. The Separate Account Performance Information
 
Although the International Growth Fund has no performance record, the Fund's
investment objectives, policies and strategies will be substantially similar to
those employed by the Sub-adviser with respect to certain separately managed
accounts of 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 employs on behalf of the Fund. The Sub-adviser Composite represents
the total return, net of all fees and expenses, of all relevant separately
managed accounts of the Sub-adviser. The inception date of the Sub-adviser
Composite was October 1, 1995.
 
The separately managed accounts in the Sub-adviser Composite were 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 registered mutual funds, their performance might
have been lower.
 
Distribution and advisory fees for the International Growth Fund are higher than
the distribution and advisory fees incurred by the funds comprising the
Templeton International Fund. The other fees and expenses incurred by the
International Growth Fund may be higher or lower than the other fees and
expenses incurred by the funds comprising the Templeton International Fund in
any given year. See "Performance and Yield Information" in the Statement of
Additional Information for a description of the manner in which performance has

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 commenced operations on               and has no
investment performance record. However, the Large Cap Growth Fund's investment
objectives, policies and strategies are substantially similar to the Goldman
Sachs CORE Large Cap Growth Fund and it is managed in substantially the same
manner and by the same individuals as 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 November 11, 1991
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. 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.
 
Distribution and advisory fees for the Large Cap Growth Fund are higher than the
distribution and advisory fees incurred by the Goldman Sachs CORE Large Cap
Growth Fund. The other fees and expenses incurred by the Large Cap Growth Fund
may be higher or lower than the other fees and expenses incurred by the Goldman
Sachs CORE Large Cap Growth Fund in any given year. See "Performance and Yield

INVESTMENT SUB-ADVISER
 
Brown Capital Management, Inc.
 
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.

MID CAP GROWTH FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Mid Cap Growth Fund commenced operations on               and has no
investment performance record. However, the Mid Cap Growth Fund's investment
objective, policies and strategies are 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
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 of the
discretionary investment accounts comprising the Combined Accounts Composite
range from January 1, 1993 to October 1, 1997.
 
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.
 
Distribution and advisory fees for the Mid Cap Growth Fund are higher than the
fees and expenses historically incurred by the Combined Accounts comprising the
Combined Accounts Composite. Consequently, the performance results for the
Combined Accounts Composite would have been adversely affected if the Combined
Accounts Composite had the same expenses as the Mid Cap Growth Fund. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of the manner in which performance has been calculated. THE

PORTFOLIO MANAGER
 
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
Fact Sheet
- --------------------------------------------------------------------------------
 
The Small Cap Growth Fund commenced operations on               and has no
investment performance record. However, the Small Cap Growth Fund's investment
objective, policies and strategies are 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 of the discretionary
accounts comprising the Combined Accounts Composite range from September 1, 1994
to June 1, 1997.
 
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 registered mutual funds, their
performance might have been lower.
 
Distribution and advisory fees for the Small Cap Growth Fund are higher than the
fees and expenses historically incurred by the Combined Accounts comprising the
Combined Accounts Composite. Consequently, the performance results for the
Combined Accounts Composite would have been adversely affected if the Combined
Accounts Composite had the same expenses as the Small Cap Growth Fund. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of the manner in which performance has been calculated. THE

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 commenced operations on                and has no
investment performance record. However, the International Value Fund's
investment objectives, policies and strategies are 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 dates of the discretionary accounts comprising the Sub-Adviser
Composite range from December 31, 1978 to March 31, 1998.
 
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 registered mutual funds, their performance might
have been lower.
 
Distribution and advisory fees for the International Value Fund are higher than

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 commenced operations on               and has no
investment performance record. However, the Large Cap Value Fund will be managed
in substantially the same manner and by the same individuals as those employed
by the Sub-adviser for Discretionary Accounts (the "Discretionary Accounts")
managed by the Sub-adviser with similar investment objectives, policies and
strategies. The Discretionary Accounts are not subject to the same investment
limitations, diversification and restriction imposed on registered mutual funds
by the 1940 Act and the Internal Revenue Code.
 
The chart below shows the investment performance for the Discretionary Accounts.
The inception date for the Discretionary Accounts range from August 1, 1992
through August 1, 1997.
The Discretionary Accounts are not subject to the investment limitations,
diversification requirements and the other restrictions imposed on registered
mutual funds by the 1940 Act and the Internal Revenue Code. If the Discretionary
Accounts had been subject to the requirements imposed on registered mutual
funds, their performance might have been lower. Consequently, the performance
results for the Discretionary Accounts would have been adversely affected if the
Discretionary Accounts had the same expenses as the Large Cap Value Fund. See

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.

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.

SOCIALLY RESPONSIBLE FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Socially Responsible Fund commenced operations              and has no
investment performance record. However, the Socially Responsible Fund's
investment objectives, policies and strategies are substantially similar to
those of the American General Series Portfolio Company Social Awareness Fund
("AGSPC Social Awareness Fund") and it is managed in substantially the same
manner and by the same individuals as AGSPC Social Awareness Fund. The chart
below shows the historical investment performance for the AGSPC Social Awareness
Fund for the period of October 2, 1989 through March 31, 1998. The inception
date for the AGSPC Social Awareness Fund was October 2, 1989.
 
Distribution and advisory fees for the Socially Responsible Fund are higher than
the distribution and advisory fees incurred by the AGSPC Social Awareness Fund.
The other fees and expenses incurred by the Socially Responsible Fund may be
higher or lower than the other fees and expenses incurred by the AGSPC Social
Awareness Fund in any given year. See "Performance and Yield Information" in the
Statement of Additional Information for a description of the manner in which
performance has been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A

PORTFOLIO MANAGERS
 
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 commenced operations on               and has no investment
performance record. However, the Balanced 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 dates of the accounts comprising
Sub-adviser Composite range from December 31, 1974 to September 30, 1997.
 
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.
 
Distribution and advisory fees for the Balanced Fund are higher than the fees
and expenses historically incurred by the accounts comprising the Sub-adviser
Composite. Consequently, the performance results for the Sub-adviser Composite
would have been adversely affected if the Sub-adviser Composite had the same
expenses as the Balanced Fund. See "Performance and Yield Information" in the
Statement of Additional Information for a description of the manner in which
performance has been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A

James S. Baker and James R. Mulally serve as the Fund's portfolio managers. Mr.
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.

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

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>   48
- --------------------------------------------------------------------------------
 
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 Mid Cap
Value Fund may invest in EDRs and/or GDRs. The Large Cap Growth Fund may invest
in GDRs but may not invest in EDRs.

of Additional Information.

SECURITIES see the

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 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 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 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:
 
  B Cash and cash equivalents
 
  B Securities issued or guaranteed by the U.S. Government, its agencies or
    instrumentalities
 
  B Certificates of deposit and other obligations of domestic banks having total
    assets in excess of $1 billion
 
  B Commercial paper sold by corporations and finance companies
 
  B Corporate debt obligations with remaining maturities of 13 months or less
 
  B 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 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, Mid Cap
Growth Fund and the International Growth Fund may invest in one or more of the
following types of futures and options:
 
  B Write exchange traded covered put and call options on securities and stock
    indices.
 
  B Purchase exchange traded put and call options on securities and stock
    indices.
 
  B Purchase and sell exchange traded financial futures contracts.
 
  B Write covered call options and purchase exchange traded put and call options
    on financial futures contracts.
 
  B 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 and the Small Cap Growth 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 and the Small Cap Growth Fund are authorized to use
warrants or rights.

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:
 
  B Market Risk
 
  B Credit (Financial) Risk
 
  B Interest Rate Risk
 
  B Risk Associated with Foreign Securities
 
  B 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.

Information.

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.
 
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 Custodians, as monitored by VALIC and authorized by
the Board of Trustees.

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 Institutional Class I
Shares of the Funds only to employee retirement plans offered through the
Distributor.
 
The Series Company was organized on March 16, 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, divided into class. Each Fund
currently offers five classes of shares, designated Class A shares, Class B
shares, Class C shares, Institutional Class I shares and Institutional Class II
shares. Other classes may be established from time to time in accordance with
provisions of the Series Company's Declaration of Trust.
 
Each class of shares represents an interest in the same assets of a Fund and
generally are identical in all respects except that each class bears certain
distribution expenses and has exclusive voting rights with respect to its
distribution fee, if any. Except as described herein, there are no conversion,
preemptive or other subscription rights. In the event of liquidation, each of
the shares of a Fund is entitled to its portion of all of the Fund's net assets
after all debts and expenses of the Fund have been paid. Since Class B and Class
C shares pay higher distribution fees and transfer agent costs, the liquidation
proceeds to Class B and Class C shareholders are likely to be lower than to
other shareholders.
 
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.
 
PURCHASE AND REDEMPTION OF SHARES
 
Institutional Class I shares of each Fund are available to you through your
employer bought from the Distributor or the Series Company through National
Financial Data Services, Inc., the Funds' transfer agent ("Transfer Agent").
 
As a participant in an employer retirement plan, you do not purchase
Institutional Class I shares of the Funds directly. Rather, Institutional Class
I shares of a Fund are purchased for you when you elect to allocate your
retirement contributions to a Fund that is available as an investment option in
your retirement or savings plan. You may be permitted to elect different
investment options, alter the amounts contributed to your plan, or change how
contributions are allocated among your investment options in accordance with
your plan's specific provisions. See your plan administrator or employee
benefits office for more details.
 
As distributor, the Distributor sells Institutional Class I shares of the Funds
to employer retirement plans. The Distributor sends orders to buy, sell or
transfer shares to the Series Company's transfer agent daily. The Series Company
may suspend the sale of any of the Fund's Institutional Class I shares to
employer retirement plans.
 
The price to purchase one share of a Fund is the Fund's net asset value per
share (NAV). Shares are sold at the public offering price based on the net asset
value next determined after the Transfer Agent receives an order. In most cases,
in order to receive that day's public offering price, the Transfer Agent must
receive an order, either directly or from the Distributor, before the close of
regular trading on the New York Stock Exchange.
 
The Distributor is a wholly-owned subsidiary of VALIC and acts as distributor of
the Funds' shares under an agreement with the Series Company. The Distributor
does not charge the Series Company or employer retirement plans for its
services. Also, the Distributor is not required to sell a minimum number of
shares to employer retirement plans.
 
For more information on how to participate in the Funds through an employee
retirement plan, please refer to your plan materials or contact your employee
benefits office.
 
TRANSFERS AND EXCHANGES
 
An employer retirement plan may allow you to exchange all or part of your
existing plan balance from one investment option to another. Check with your
plan administrator for details on the rules governing exchanges in your plan.
Certain investment options, particularly company stock or guaranteed investment
contracts (GICs), may

be subject to unique restrictions. Exchanges will be accepted by the Series
Company only as permitted by your plan. Your plan administrator can explain how
frequently exchanges are allowed. The Series Company reserves the right to
refuse any exchange purchase request.
 
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 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 the Distributor, an employer plan sends 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. The Money
Market Fund pays dividends daily, the International Growth Fund, the Large Cap
Value Fund and the Small Cap Value Fund pay dividends quarterly and all other
Funds pay dividends once a month.
 
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 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 under an employer plan, you vote on these matters indirectly by
voting your shares. The way you vote your shares as a participant depends on
your employer plan.
 
See the Statement of Additional 
Information and your contract 
prospectus for further tax
discussions. You should also
consult your tax advisor before
investing.
 
 48
<PAGE>   55
- --------------------------------------------------------------------------------
 
When a matter comes up for vote, the employer plan will vote its shares in the
same proportion as the share 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 shares, it may decide to vote that way.
 
Controlling Shareholder
 
VALIC, as the initial sole shareholder 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.
 
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:
 
  B to approve certain agreements as required by the 1940 Act;
 
  B to change fundamental investment objectives in the Diversification section
    and to change fundamental investment restrictions, above;
 
  B 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 participants or other investors. 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.

Unless otherwise specified in this prospectus, the words we, our, and VALIC mean
The Variable Annuity Life Insurance Company. The words you and your mean the
participant.
 
American General Series Portfolio Company 2 (the "Series Company") was organized
as a Delaware business trust on March 16, 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, supervise the purchase and sale of
Fund investments and perform the cash management function. However, we make
investment decisions for, and are 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.
 
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].
 
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.

FEE TABLE
- --------------------------------------------------------------------------------
 
FUND OPERATING EXPENSES ARE BASED ON CURRENT ESTIMATES AND ARE SUBJECT TO
MODIFICATION PRIOR TO EFFECTIVENESS.
 
The following tables illustrate the fees and expenses that investors bear
directly or indirectly as shareholders of the Funds. Shareholder transaction
expenses are the charges that an investor pays to purchase or redeem shares of a
Fund. Annual fund operating expenses are the fees paid out of the assets of a
Fund. Each Fund pays a management fee to VALIC and a distribution and/or service
fee to the Distributor. 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.

ABOUT THE FUND'S MANAGEMENT
- --------------------------------------------------------------------------------
 
INVESTMENT ADVISER
 
VALIC, a stock life insurance company, has been in the investment advisory
business since 1960. VALIC has been the Investment Adviser for the Funds that
comprise the Series Company since their inception.
 
VALIC is a member of the American General Corporation group of companies.
Members of the American General Corporation group of companies operate in each
of the 50 states and Canada and collectively provide financial services with
activities heavily weighted toward insurance.
 
As Investment Adviser, VALIC oversees the Funds' day to day operations. Also,
VALIC supervises the purchase and sale of Fund investments and performs the cash
management formation. 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. VALIC serves as Investment
Adviser through an Investment Advisory Agreement it enters into with each Fund.
After the second year, this agreement will be renewed once each year, by the
Series Company Board of Trustees.
 
One Investment Advisory Agreement dated [               , 1998] covers all 18
Funds.
 
For more information about the Advisory Agreement, see the "Investment Adviser"
section in the Statement of Additional Information.
 
INVESTMENT SUB-ADVISERS
 
For some of the Funds, VALIC works with Investment Sub-advisers, financial
service companies that specialize in certain types of investing. However, VALIC
still retains ultimate responsibility for managing the Funds. The Sub-adviser's
role is to make investment decisions for the Funds according to each Fund's
investment objectives and restrictions.
 
In selecting Sub-advisers, the Trustees carefully evaluated: (i) the nature and
quality of the services expected to be rendered to the Fund(s) by the
Sub-adviser; (ii) the distinct investment objective and policies of the Fund(s);
(iii) the history, reputation, qualification and background of the Sub-
advisers' personnel and its financial condition; (iv) its performance track
record; and (v) other factors deemed relevant. The Trustees also reviewed the
fees to be paid to each Sub-adviser.

These financial service companies act as Investment Sub-advisers through an
agreement each entered into with VALIC. For more information on these agreements
and on these Sub-advisers, see the "Investment Sub-Advisers" section in the
Statement of Additional Information.
 
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.

The Investment Advisory Agreement we entered into with each Fund does not limit
how much the Funds pay in monthly expenses each year.
 
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.
 
From time to time VALIC, the Sub-adviser and/or the Distributor may voluntarily
undertake to reduce the Fund's expenses by reducing the fees payable to them to
the extent of, or bearing expenses in excess of, such limitations as they may
establish.

THE SUB-ADVISERS
 
The Funds do not pay the Sub-advisers directly. According to the agreements
VALIC pays them a fee based on the Fund's average monthly net market value. 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 terminate,
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

pay Capital Guardian a quarterly 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 all fees if total fees are between $1.25
million and $4 million, a 7.5% discount to all fees if total fees are between $4
million and $8 million, a 10% discount to all fees if total fees are between $8
million and $12 million, and a 12.5% discount to all fees if total fees exceed
$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

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
Advisors, we pay State Street Global Advisors 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 twelve members: nine
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, STABILITY AND LIFESTYLE 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 CATEGORY
 
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.
 
                                                                               9
<PAGE>   69

The anticipated portfolio turnover rates for each of the Funds except the Money
Market Fund are as follows:

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

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 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.
 
                                                                              11
<PAGE>   71
- --------------------------------------------------------------------------------
 
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.

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

The Mid Cap Index Fund commenced operations on              and has no
investment performance record. However, the Mid Cap Index Fund's investment
objectives, policies and strategies are substantially similar to the American
General Series Portfolio Company's Mid Cap Index Fund ("AGSPC Mid Cap Index
Fund") and it is managed in substantially the same manner and by the same
individuals as the AGSPC Mid Cap Index Fund. The chart below shows the
investment performance for the AGSPC Mid Cap Index Fund in two separate sets of
tables and graphs for the ten year period beginning April 1, 1988 and for the
period beginning October 1, 1991. The latter period shows the performance of the
AGSPC Mid Cap Index Fund since the change in investment objectives, investment
program and investment restrictions of the underlying Fund. The inception date
for the AGSPC Mid Cap Index Fund was October 13, 1982.
 
Distribution and advisory fees for the Mid Cap Index Fund are higher than the
distribution and advisory fees incurred by the AGSPC Mid Cap Index Fund. The
other fees and expenses incurred by the Mid Cap Index Fund may be higher or

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.
 
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 Russell 2000 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 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.

SMALL CAP INDEX FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Small Cap Index Fund commenced operations on              and has no
investment performance record. However, the Fund's investment objectives,
policies and strategies are substantially similar to the BT Pyramid Russell 2000
Index Fund and it is managed in substantially the same manner and by the same
individuals as the BT Pyramid Russell 2000 Index Fund. The chart below shows the
investment performance for BT Pyramid Russell 2000 Index Fund for the period
April 1, 1988 through March 31, 1998. The inception date for BT Pyramid Russell
2000 Index Fund was October 31, 1987.
 
Distribution and advisory fees for the Small Cap Index Fund are higher than the
distribution and advisory fees incurred by the BT Pyramid Russell 2000 Index
Fund. The other fees and expenses incurred by the Small Cap Index Fund may be
higher or lower than the other fees and expenses incurred by the BT Pyramid
Russell 2000 Index Fund in any given year. See "Performance and Yield
Information" in the Statement of Additional Information for a description of the
manner in which performance has been calculated. THE PERFORMANCE INFORMATION

Jacobs Asset Management
 
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.

  *** An "emerging country" security is issued by a
      Company that in our opinion has one or more of the following
      characteristics: (i) its principal securities trading market is in an
      emerging country; (ii) alone or on a consolidated basis, it derives 50% or
      more of its annual revenue from either goods produced, sales made or
      services performed in emerging countries, or (iii) it is organized under
      the laws of, and has a principal office in, an emerging country.
 
 **** Small capitalization companies are companies with
      market capitalizations of less than $1 billion at the time of purchase.
 
***** For temporary defensive reasons, we may invest up
      to 100% of the Fund's assets in short-term (less than twelve months to
      maturity) securities or cash, including domestic and foreign money market
      instruments, certificates of deposit, bankers' acceptances, time deposits,
      U.S. Government obligations, U.S. Government agency securities, short-term
      corporate debt securities, and commercial paper rated A-1 or A-2 by S&P or
      Prime 1 or Prime 2 by Moody's or if unrated, in our opinion of comparable
      quality. We may do this when we think economic, political or market
      conditions make it too risky for us to follow our general guidelines.

INTERNATIONAL GROWTH FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
1. The Templeton Performance Information
 
The International Growth Fund commenced operations on                and has no
investment performance record. The performance information shown below is for
the Templeton International Fund, a series of the Templeton Variable Products
Series Fund, which was managed by Mr. Jacobs, a principal of the Sub-adviser.
The Templeton International Fund has substantially similar, though not
necessarily identical objectives, policies and strategies as the International
Growth Fund. The chart below shows the historical investment performance for the
year-ended June 30, 1995 and the three-years ended 1995. The inception date for
the Templeton International Fund was May 1, 1992. During Mr. Jacobs ten years as
the portfolio manager of the fund, from May 1, 1992 to June 30, 1995, he was
primarily responsible for the day-to-day management of the fund, and no other
person had a significant role in scheduling the fund's performance.
 
Distribution and advisory fees for the International Growth Fund are higher than
the distribution and advisory fees incurred by the funds comprising the
Composite. The other fees and expenses incurred by the International Growth Fund
may be higher or lower than the other fees and expenses incurred by the funds
comprising the Composite in any given year. See "Performance and Yield
Information" in the Statement of Additional Information for a description of the
manner in which performance has been calculated. THE PERFORMANCE INFORMATION

2. The Separate Account Performance Information
 
Although the International Growth Fund has no performance record, the Fund's
investment objectives, policies and strategies will be substantially similar to
those employed by the Sub-adviser with respect to certain separately managed
accounts of 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 employs on behalf of the Fund. The Sub-adviser Composite represents
the total return, net of all fees and expenses, of all relevant separately
managed accounts of the Sub-adviser. The inception date of the Sub-adviser
Composite was October 1, 1995.
 
The separately managed accounts in the Sub-adviser Composite were 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 registered mutual funds, their performance might
have been lower.
 
Distribution and advisory fees for the International Growth Fund are higher than
the distribution and advisory fees incurred by the funds comprising the
Templeton International Fund. The other fees and expenses incurred by the
International Growth Fund may be higher or lower than the other fees and
expenses incurred by the funds comprising the Templeton International Fund in
any given year. See "Performance and Yield Information" in the Statement of
Additional Information for a description of the manner in which performance has
been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A COMPOSITE

Goldman Sachs Asset Management
 
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 commenced operations on               and has no
investment performance record. However, the Large Cap Growth Fund's investment
objectives, policies and strategies are substantially similar to the Goldman
Sachs CORE Large Cap Growth Fund and it is managed in substantially the same
manner and by the same individuals as 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 November 11, 1991
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. 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.
 
Distribution and advisory fees for the Large Cap Growth Fund are higher than the
distribution and advisory fees incurred by the Goldman Sachs CORE Large Cap
Growth Fund. The other fees and expenses incurred by the Large Cap Growth Fund
may be higher or lower than the other fees and expenses incurred by the Goldman
Sachs CORE Large Cap Growth Fund in any given year. See "Performance and Yield

VALIC
 
INVESTMENT SUB-ADVISER
 
Brown Capital Management, Inc.
 
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

MID CAP GROWTH FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Mid Cap Growth Fund commenced operations on               and has no
investment performance record. However, the Mid Cap Growth Fund's investment
objective, policies and strategies are 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
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 of the
discretionary investment accounts comprising the Combined Accounts Composite
range from January 1, 1993 to October 1, 1997.
 
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.
 
Distribution and advisory fees for the Mid Cap Growth Fund are higher than the
fees and expenses historically incurred by the Combined Accounts comprising the
Combined Accounts Composite. Consequently, the performance results for the
Combined Accounts Composite would have been adversely affected if the Combined
Accounts Composite had the same expenses as the Mid Cap Growth Fund. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of the manner in which performance has been calculated. THE

PORTFOLIO MANAGER
 
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.

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 commenced operations on                and has no
investment performance record. However, the International Value Fund's
investment objectives, policies and strategies are 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 dates of the discretionary accounts comprising the Sub-Adviser
Composite range from December 31, 1978 to March 31, 1998.
 
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 registered mutual funds, their performance might

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 commenced operations on               and has no
investment performance record. However, the Large Cap Value Fund will be managed
in substantially the same manner and by the same individuals as those employed
by the Sub-adviser for Discretionary Accounts (the "Discretionary Accounts")
managed by the Sub-adviser with similar investment objectives, policies and
strategies. The Discretionary Accounts are not subject to the same investment
limitations, diversification and restriction imposed on registered mutual funds
by the 1940 Act and the Internal Revenue Code.
 
The chart below shows the investment performance for the Discretionary Accounts.
The inception date for the Discretionary Accounts range from August 1, 1992
through August 1, 1997.
The Discretionary Accounts are not subject to the investment limitations,
diversification requirements and the other restrictions imposed on registered
mutual funds by the 1940 Act and the Internal Revenue Code. If the Discretionary
Accounts had been subject to the requirements imposed on registered mutual
funds, their performance might have been lower. Consequently, the performance
results for the Discretionary Accounts would have been adversely affected if the
Discretionary Accounts had the same expenses as the Large Cap Value Fund. See

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 commenced operations on               and has no
investment performance record. However, the Mid Cap Value Fund's investment
objectives, policies and strategies are substantially similar to those of the
Neuberger & Berman Partners Fund and it is managed in substantially the same
manner and by the same individuals as the Neuberger & Berman Partners Fund. The
chart below shows the investment performance for the Neuberger & Berman Partners
Fund for the period April 1, 1998 through March 31, 1999. The date the
Sub-Adviser assumed management of the Neuberger & Berman Partners Fund was
January 20, 1975.
 
Distribution and advisory fees for the Mid Cap Value Fund are higher than the
distribution and advisory fees incurred by the Neuberger & Berman Partners Fund.
The other fees and expenses incurred by the Mid Cap Value Fund may be higher or
lower than the other fees and expenses incurred by the Neuberger & Berman
Partners Fund in any given year. See "Performance and Yield Information" in the
Statement of Additional Information for a description of the manner in which
performance has been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A

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.

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 commenced operations on               and has no investment
performance record. However, the Balanced 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 dates of the accounts comprising
Sub-adviser Composite range from December 31, 1974 to September 30, 1997.
 
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.
 
Distribution and advisory fees for the Balanced Fund are higher than the fees
and expenses historically incurred by the accounts comprising the Sub-adviser
Composite. Consequently, the performance results for the Sub-adviser Composite
would have been adversely affected if the Sub-adviser Composite had the same
expenses as the Balanced Fund. See "Performance and Yield Information" in the
Statement of Additional Information for a description of the manner in which
performance has been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A

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.
 
We follow the guidelines listed below for making the primary investments for the
Fund.

DOMESTIC BOND FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Domestic Bond Fund commenced operations on               and has no
investment performance record. However, the Domestic Bond 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 dates of the
account comprising Sub-adviser Composite range from December 31, 1972 to March
1, 1998.
 
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.
 
Distribution and advisory fees for the Domestic Bond Fund are higher than the
fees and expenses historically incurred by the accounts comprising the
Sub-adviser Composite. Consequently, the performance results for the Sub-adviser
Composite would have been adversely affected if the Sub-adviser Composite had
the same expenses as the Domestic Bond Fund. See "Performance and Yield
Information" in the Statement of Additional Information for a description of the
manner in which performance has been calculated. THE PERFORMANCE INFORMATION
BELOW IS BASED ON A COMPOSITE COMPARABLE TO THE DOMESTIC BOND 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)*

Series Company since its inception. Since 1987, Mr. Trimbur has served as Vice
President and Investment Officer of American General Series Portfolio Company, a

INVESTMENT OBJECTIVE
 
Seeks growth through investments in Series Company Funds. This Fund is suitable
for investors seeking the potential for capital growth that a fund investing
predominately in common stocks may offer.

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.
 
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
 
ISSUED means the
Company (ISSUER) sold it
originally to the public.

Information.

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 Mid Cap
Value Fund may invest in EDRs and 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 and 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 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.

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 Mid Cap
Growth 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.
 
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 Subadviser'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.
 
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.

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. The Series Company was organized on March 16, 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,
divided into class. Each Fund currently offers five classes of shares,
designated Class A shares, Class B shares, Class C shares, Institutional Class I
shares and Institutional Class II shares. Other classes may be established from
time to time in accordance with provisions of the Series Company's Declaration
of Trust.
 
Each class of shares represents an interest in the same assets of a Fund and
generally are identical in all respects except that each class bears certain
distribution expenses and has exclusive voting rights with respect to its
distribution fee, if any. Except as described herein, there are no conversion,
preemptive or other subscription rights. In the event of liquidation, each of
the shares of a Fund is entitled to its portion of all of the Fund's net assets
after all debts and expenses of the Fund have been paid. Since Class B and Class
C shares pay higher distribution fees and transfer agent costs, the liquidation
proceeds to Class B and Class C shareholders are likely to be lower than to
other shareholders.
 
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.

The different ways to set up an account with the Distributor are listed below.
 
INDIVIDUAL OR JOINT TENANT
 
Individual accounts are owned by one person. Joint accounts can have two or more

    certain income limits.
 
  - ROTH IRAS allow individuals to make non-deductible contributions of up to
    $2,000 per tax year. Married couples can contribute up to $4,000 per tax
    year, provided no more than $2,000 is contributed on behalf of either
    spouse. (These limits are aggregated for Traditional and Roth IRAs.)
    Eligibility is subject to certain income limits. Qualified distributions are
    tax free.
 
  - ROTH CONVERSION IRAS allow individuals with assets held in a Traditional IRA
    or Rollover IRA to convert those assets to a Roth Conversion IRA.
    Eligibility is subject to certain income limits. Qualified distributions are
    tax-free.

    rollover distributions from employer-sponsored retirement plans.
 
  - PROFIT SHARING OR MONEY PURCHASE PENSION PLANS (KEOGHS) allow self-employed
    individuals or small business owners to make tax-deductible contributions
    for themselves and any eligible employees.

SALES ARRANGEMENTS
 
The Series Company offers three classes of Fund shares to you on a continuous
basis through the Distributor, an affiliate of VALIC.
 
  - CLASS A SHARES. An investor who purchases Class A shares pays a sales charge
    at the time of purchase. Class A shares are not subject to any charges when
    they are redeemed. However, certain purchases of Class A shares qualify for
    reduced sales charges. Class A shares are subject to an ongoing service fee
    at an annual rate of 0.25% of each Fund's aggregate average daily net assets
    attributable to Class A shares. See "Purchase and Redemption of Shares" and
    "Distribution and Service Plans."
 
  - CLASS B SHARES. Class B shares are sold without an initial sales charge but
    are subject to a contingent deferred sales charge ("CDSC") if redeemed
    within a specified period after purchase. Class B shares provide an investor
    the benefit of putting all the investor's dollars to work from the time the
    investment is made. Class B shares are subject to an ongoing distribution
    fee at an annual rate of 0.75% and a service fee at an annual rate of 0.25%
    of each Fund's aggregate average daily net assets attributable to Class B
    shares. As a result of the distribution fee that Class B shares pay, Class B
    shares have a higher expense ratio and pay lower dividends than Class A
    shares. Class B shares convert automatically to Class A shares eight years
    after the end of the calendar month in which a shareholder's order to
    purchase was accepted. See "Purchase and Redemption of Shares,"
    "Distribution and Service Plans," and "Conversion Feature."
 
  - CLASS C SHARES. An investor who purchases Class C shares pays no initial
    sales charge but is subject to a CDSC if the investor redeems Class C shares
    within one year of the date of purchase. Class C shares are subject to an
    ongoing distribution fee at an annual rate of 0.75% and a service fee at an
    annual rate of 0.25% of each Fund's aggregate average daily net assets
    attributable to Class C shares. As a result of the distribution fee that
    Class C shares pay, Class C shares have a higher expense ratio and pay lower
    dividends than Class A shares. See "Purchase and Redemption of Shares" and
    "Distribution and Service Plans."
 
  - CONVERSION FEATURE. Class B shares will convert automatically to Class A
    shares eight years after the shares were purchased and will no longer be
    subject to the distribution fee. The conversion will be based on the net
    asset values of Class B and Class A shares, respectively. Class B shares
    acquired through the reinvestment of dividends will be held in a separate
    sub-account. Each time Class B shares (other than those in the sub-account)
    convert to Class A shares, an equal pro rata portion of the Class B shares
    in the sub-account will also convert to Class A shares.
 
WHICH ARRANGEMENT IS BEST FOR YOU? The decision as to which class of shares
provides a more suitable investment for an investor depends on a number of
factors, including the amount and intended length of the investment. Investors
making investments that qualify for reduced sales charges might consider Class A
shares. Investors who prefer not to pay an initial sales charge might consider
Class B or Class C shares. Orders for Class B shares for [$500,000] or more will
be treated as orders for Class A shares or declined. Orders for Class C shares
for $1 million or more will be treated as orders for Class A shares or declined.
Shares of a Series Company Fund may
 
 56
<PAGE>   116
- --------------------------------------------------------------------------------
 
only be exchanged for shares of the same class of another Series Company Fund.
For more information about these sales arrangements, consult the Distributor.
 
[With respect to the Money Market Fund, unless you intend to exchange your Fund
shares for Class B or Class C shares of other Series Company Funds, you should
purchase the Fund's Class A shares because there is no distribution fee. Even if
you intend to exchange your Fund shares for Class B or Class C shares of other
Series Company Funds you may prefer to purchase Class A shares of such Fund and
then redeem those shares and use the proceeds to purchase Class B or Class C
shares of other Service Company Funds.]
 
PURCHASE AND REDEMPTION OF SHARES
 
HOW TO BUY FUND SHARES
 
The price to purchase one share of a Fund is the Fund's offering price or net
asset value per share (NAV), depending on whether you pay a sales charge. If you
purchase shares and pay a sales charge, your price will be the fund's offering
price. When you purchase shares of a Fund at the offering price, the Series
Company deducts the appropriate sales charge and invests the rest in the Fund.
If you qualify for a sales charge waiver, your price will be the Fund's NAV. See
"Purchases and Redemptions of Shares -- General" for an explanation of how and
when sales charges and waiver apply.
 
You can buy Fund shares through the Series Company by contacting Boston
Financial Data Services , the Funds' transfer agent ("Transfer Agent"), at
1-800-         , through the Distributor, by contacting the Distributor at
1-800-         , or through a systematic investment plan.
 
Initial investments must be at least [$500] for each class of shares and
subsequent investments must be at least [$25]. The [$500] minimum may be waived
by the Distributor for investors purchasing shares through systematic investing.
 
BUYING SHARES THROUGH THE SERIES COMPANY. You may purchase shares through the
Series Company by sending a completed order form and a check for the amount you
wish to invest, to the Transfer Agent. Please indicate on the order form the
Fund and the class of shares in which you wish to invest.
 
BUYING SHARES THROUGH THE DISTRIBUTOR. Shares may be purchased on any business
day by completing an order form and writing a check for the amount you wish to
invest, payable to the Distributor. Return the completed form and check to the
Distributor, indicating the Fund and the class of shares in which you wish to
invest.
 
BUYING SHARES THROUGH SYSTEMATIC INVESTING. You can make regular investments of
[$25] or more per month through automatic deductions from your bank checking or
savings account. Application forms are available from the Distributor.
 
BUYING SHARES THROUGH A RETIREMENT PLAN. To purchase Fund shares through a
tax-advantaged retirement plan, such as an IRA, you will need a special
application. Retirement investing also involves its own investment procedures.
Call the Distributor at [1-800-         (toll free)] for more information and an
application. Shares are sold at the public offering price based on the net asset
value next determined after the Transfer Agent receives your order. In most
cases, in order to receive that day's public offering price, the Transfer Agent
must receive your order, either directly or from the Distributor, before the
close of regular trading on the New York Stock Exchange.
 
CLASS A SHARES
 
The public offering price of Class A shares is the net asset value plus a sales
charge that varies depending on the size of your purchase. The Fund whose shares
you purchase receives the net asset value. The sales charge is allocated between
the Distributor and the Series Company as shown in the following table, except
when the Series Company, in its discretion, allocates the entire amount to the
Distributor.

There is no initial sales charges on purchases of Class A shares of [$1 million
or more]. However, a CDSC of [1.00%] will be imposed on redemptions within one
year of purchase.
 
In determining whether a CDSC is payable, shares not subject to any charge will
be redeemed first followed by shares held longest during the CDSC period. Any
CDSC will be based on the lower of the shares' cost and current net asset value.
Any shares acquired by reinvestment of distributions will be redeemed without a
CDSC. The Distributor receives the entire amount of any CDSC you pay.

[$1 million or more] based on an investor's cumulative purchases during the
one-year period beginning with the date of the initial purchase at net asset
value. Each subsequent one-year measuring period for these purposes will begin
with the first net asset value purchase following the end of the prior period.
Such commissions are paid at the rate of [1.00% of the amount under $3 million,
0.50% of the net $47 million and 0.25% thereafter].
 
CLASS B SHARES
 
Class B Shares are sold without an initial sales charge, although a CDSC will be
imposed if you redeem shares within a specified period after purchase as shown
in the table below. The following types of shares may be redeemed without charge
at any time: (i) shares acquired by reinvestment of distributions, and (ii)
shares otherwise exempt from the CDSC, as described in "Purchase and Redemption
of Shares -- General" below. For other shares, the amount of the charge is
determined as a percentage of the lesser of the current market value or the cost
of shares being redeemed.

   CHARGE
 
In determining whether a CDSC is payable on any redemption, shares not subject
to any charge will be redeemed first, followed by shares held the longest during
the CDSC period. For this purpose, the amount of any increase in a share's value
above its initial purchase price is not regarded as a share exempt from CDSC.
Thus, when a share that has appreciated in value is redeemed during the CDSC
period, a CDSC is assessed only on its initial purchase price. The Distributor
receives the entire amount of any CDSC you pay. Class B shares will
automatically convert to Class A shares eight years after the shares were
purchased. See "Sales Arrangements -- Conversion Feature."
 
CLASS C SHARES
 
Class C shares are sold without an initial sales charge, although a CDSC of
1.00% will be imposed if you redeem Class C shares within one year of the date
of purchase. The following types of shares may be redeemed without charge at any
time: (i) shares acquired by reinvestment of distributions, and (ii) shares
otherwise exempt from the redemption fee, as described in "Purchase and
Redemption of Shares -- General" below. For other shares, the amount of the
redemption fee is 1.00% of the lesser of the current market value of the shares
redeemed or the total cost of such shares. The Distributor receives the entire
CDSC.
 
GENERAL
 
YOU MAY BE ELIGIBLE TO BUY FUND SHARES AT REDUCED SALES CHARGES.
 
Consult the Distributor or the Series Company for details about the Series
Company's combined purchase privilege, cumulative quantity discount, statement
of intention, group sales plan and other plans. Descriptions are also included
in the order form and in the Statement of Additional Information.
 
The Series Company may sell Class A, Class B and Class C shares at net asset
value without an initial sales charge, or a CDSC to current and retired Trustees
(and their families), current and retired employees (and their families) of the
Series Company and affiliates, registered representatives and other employees
(and their families) of the Distributor, financial institution trust departments
investing an aggregate of $1 million or more in the Funds, clients of certain
administrators of tax-qualified plans, tax-qualified plans when proceeds from
repayments of loans to participants are invested or reinvested in the Funds, and
"wrap accounts" for the benefit of clients of broker-dealers, financial
institutions or financial planners adhering to standards established by the
Series Company.
 
In addition, the CDSC or redemption fee will be waived on redemptions of shares
arising out of the death or post-purchase disability of an investor or settlor
of a living trust account, and on redemptions in connection with certain
withdrawals from IRA or other retirement plans. Up to 12% of the value of shares
subject to a systematic withdrawal plan may also be redeemed each year without a
CDSC or redemption fee. The Statement of Additional Information contains
additional information about purchasing shares at reduced sales charges.
 
If you are considering redeeming or exchanging shares or transferring shares to
another person shortly after purchase, you should pay for those shares with a
certified check to avoid any delay in redemption, exchange or transfer.
Otherwise, payment may be delayed until the purchase price of those shares has
been collected or, if you redeem by telephone, until 15 calendar days after the
purchase date. To eliminate the need for safekeeping, certificates will not be
issued for your shares unless you request them.
 
The Distributor will from time to time, at its expense, provide additional
promotional incentives or payments to the Distributor's registered
representatives. These incentives or payments may include payments for travel
expenses, including lodging, incurred in connection with trips taken by invited
registered representatives and their guests to locations within and outside

DISTRIBUTION AND SERVICE PLANS
 
The Series Company has adopted a Distribution and Service Plan (the "Plan") for
Class A, Class B and Class C shares under Rule 12b-1 of the 1940 Act. The Plan
authorizes the Series Company to pay the Distributor a distribution and/or
service fee equal on an annual basis to 0.25% of each Fund's average daily net
assets attributable to Class A shares. The amount paid to the Distributor is in
connection with its activities and expenses in providing services to
shareholders and/or maintaining shareholder accounts [and for advertising,
marketing and distributing the Fund's shares]. In particular, the Plan and a
related Distribution and Service Agreement between the Series Company and the
Distributor contemplate the amount paid to the Distributor's servicing agents
and/or other broker-dealers with whom the Distributor has entered into an
agreement to be used for providing general shareholder liaison services, helping
to establish and maintain shareholder accounts and records, helping with
requests to buy and sell shares, receiving and answering correspondence,
monitoring dividend payments from each Fund on behalf of shareholder, and
similar servicing and account maintenance activities.
 
Furthermore, the Plan authorizes the Series Company to pay the Distributor a
distribution fee equal on an annual basis to 0.75% of each Fund's average daily
net assets attributable to Class B and Class C shares and a service fee equal on
an annual basis to 0.25% of each Fund's average daily net assets attributable to
Class B and Class C shares. The distribution fee is paid to the Distributor for
selling and promoting Class B and Class C shares. The Distributor's distribution
expenses may include sales commissions and compensation to registered
representatives, payments to sales and marketing personnel, advertising
expenditures and the costs of preparing and distributing promotional material.
The service fee will be used to pay the Distributor's servicing agents and/or
for helping to establish and maintain accounts and records, providing
shareholder liaison services, helping with requests to buy and sell shares,
receiving and answering correspondence, monitoring dividend payments from each
Fund on behalf of Class B and Class C shareholders, and similar servicing and
account maintenance activities. See the Statement of Additional Information for
more information about the Distribution and Service Plan.
 
HOW TO SELL FUND SHARES
 
You can sell your shares to the Series Company any day the New York Stock
Exchange is open, either directly or through the Distributor. The Series Company
will only redeem shares for which it has received payment.
 
SELLING SHARES DIRECTLY TO THE SERIES COMPANY
 
Send a signed letter of instruction or stock power to the Transfer Agent, along
with any certificates that represent shares you want to sell. The price you will
receive is the next net asset value calculated after the Transfer Agent receives
your request in proper form less any applicable CDSC or redemption fee. In order
to receive that day's net asset value, the Transfer Agent must receive your
request before the close of regular trading on the New York Stock Exchange.
 
If you sell shares having a net asset value of [$100,000] or more, the
signatures of registered owners or their legal representatives must be
guaranteed by a bank, broker-dealer or certain other financial institutions. See
the Statement of Additional Information for more information about where to
obtain a signature guarantee. Stock power forms are available from the Transfer
Agent, the Distributor and many commercial banks.
 
If you want redemption proceeds to be sent to an address other than your address
as it appears on the Series Company's records, a signature guarantee is
required. The Transfer Agent usually requires additional documentation for the
sale of shares by a corporation, partnership, agent or fiduciary, or a surviving
joint owner. Contact the Transfer Agent for details.
 
The Series Company generally sends you payment for your shares the business day
after your request is received. Under unusual circumstances, the Series Company
may suspend redemptions, or postpone payment for more than seven days, as
permitted by federal securities law.
 
Your Telephone Redemption Privilege allows you to redeem shares valued up to
[$100,000] from your account by telephone, unless you have notified the Transfer
Agent of an address change within the preceding 15 days. Unless an investor
indicates otherwise on the account application, the Transfer Agent will be
authorized to act upon redemption and transfer instructions received by
telephone from an investor, or any person claiming to act as his or her
representative, who can provide the Transfer Agent with his or her account
registration and address as it appears on the Transfer Agent records.
 
The Transfer Agent will employ these and other reasonable procedures to confirm
that instructions communicated by telephone are genuine: if it fails to employ
reasonable procedures, the Transfer Agent may be liable for any losses due to
 
See the Statement of Additional
information and your contract
prospectus for further tax
discussions. You should also
consult your tax advisor
before investing.
 
                                                                              59
<PAGE>   119
 
- --------------------------------------------------------------------------------
 
unauthorized or fraudulent instructions. For information, contact the Transfer
Agent.
 
During periods of unusual market changes and investor activity, you may
experience delays in contacting the Transfer Agent by telephone. In this event,
you may wish to submit a written redemption request, as described above, or
contact the Distributor, as described below. The Telephone Redemption Privilege
is not available if you were issued certificates for your shares that remain
outstanding. The Telephone Redemption Privilege may be modified or terminated
without notice.
 
SELLING SHARES THROUGH THE DISTRIBUTOR
 
The Distributor must receive your redemption request before the close of regular
trading on the New York Stock Exchange to receive that day's net asset value.
The Distributor will be responsible for providing all necessary documentation to
the Transfer Agent and may charge for its services.
 
EXCHANGES OF SHARES
 
You may exchange your Fund shares for shares of the same class of another Fund
at net asset value. If you exchange shares subject to a CDSC or redemption fee,
the transaction will not be subject to the CDSC or redemption fee. However, when
you redeem shares acquired through the exchange, the redemption may be subject
to the CDSC or redemption fee, depending upon when you originally purchased the
shares. For purposes of computing the applicable CDSC or redemption fee, the
length of time you have owned your shares will be measured from the date of
original purchase and will not be affected by any exchange.
 
To exchange your shares, simply complete an Exchange Authorization Form and send
it to the Transfer Agent. For federal income tax purposes, an exchange is
treated as a sale of shares and generally results in a capital gain or loss. A
Telephone Exchange Privilege is currently available for amounts up to
[$500,000]. The Transfer Agent's procedures for telephonic transactions are
described under "How to Sell Fund Shares." The Telephone Exchange privilege is
not available if you were issued certificates for shares that remain
outstanding.
 
The exchange privilege is not intended as a vehicle for short-term trading.
Excessive exchange activity may interfere with portfolio management and have an
adverse effect on all investors. In order to limit excessive exchange activity
and in other circumstances where VALIC or the Trustees believe doing so would be
in the best interests of a Fund, the Series Company reserves the right to revise
or terminate the exchange privilege, limit the amount or number of exchanges or
reject any exchange. Consult the Transfer Agent before requesting an exchange.
See the Statement of Additional Information to find out more about the exchange
privilege.
 
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 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.)
 
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. The Money
Market Fund pays dividends daily, the International Growth Fund, the Large Cap
Value Fund and the Small Cap Value Fund pay dividends quarterly and all other
Funds pay dividends once a month.
 
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.
 
 60
<PAGE>   120
 
- --------------------------------------------------------------------------------
 
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 it can
invest more of its assets in fewer issuers and for this reason may be riskier
than the other Funds. This Fund may invest up to 25% of its 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 the 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.
 
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.
 
Controlling Shareholder
 
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 affect the
rights of future shareholders.
 
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 or other investors. 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.

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 2 (the "Series Company") was organized
as a Delaware business trust on March 16, 1998.
 
The Series Company is an open-end management investment company and currently
consists of 18 different Funds, 15 of which are 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, supervise the purchase and sale of
Fund investments and perform the cash management function. 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 employer plan that purchases shares of the Funds through
the Distributor. Most often employers establish retirement plans 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 employer's
plan materials.
 
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 employer plan,
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 or leave it in the account until you
need it. 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.]
 
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.

FEE TABLE
- --------------------------------------------------------------------------------
 
FUND OPERATING EXPENSES ARE BASED ON CURRENT ESTIMATES AND ARE SUBJECT TO
MODIFICATION PRIOR TO EFFECTIVENESS.
 
The following tables illustrate the fees and expenses that investors bear
directly or indirectly as shareholders of the Funds. Shareholder transaction
expenses are the charges that an investor pays to purchase or redeem shares of a
Fund. 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.

ABOUT THE FUND'S MANAGEMENT
- --------------------------------------------------------------------------------
 
INVESTMENT ADVISER
 
VALIC, a stock life insurance company, has been in the investment advisory
business since 1960. VALIC has been the Investment Adviser for the Funds that
comprise the Series Company since their inception.
 
VALIC is a member of the American General Corporation group of companies.
Members of the American General Corporation group of companies operate in each
of the 50 states and Canada and collectively provide financial services with
activities heavily weighted toward insurance.
 
As Investment Adviser, VALIC oversees the Funds' day to day operations. Also,
VALIC supervises the purchase and sale of Fund investments and performs the cash
management function. 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. VALIC serves as Investment Adviser
through an Investment Advisory Agreement it enters into with each Fund. After
the second year, this agreement will be renewed once each year, by the Series
Company Board of Trustees.
 
One Investment Advisory Agreement dated [            , 1998] covers all 18
Funds.
 
For more information about the Advisory Agreement, see the "Investment Adviser"
section in the Statement of Additional Information.
 
INVESTMENT SUB-ADVISERS
 
For some of the Funds, VALIC works with Investment Sub-advisers, financial
service companies that specialize in certain types of investing. However, VALIC
still retains ultimate responsibility for managing the Funds. The Sub-adviser's
role is to make investment decisions for the Funds according to each Fund's
investment objectives and restrictions.
 
In selecting Sub-advisers, the Trustees carefully evaluated: (i) the nature and
quality of the services expected to be rendered to the Fund(s) by the
Sub-adviser; (ii) the distinct investment objective and policies of the Fund(s);
(iii) the history, reputation, qualification and background of the Sub-
advisers' personnel and its financial condition; (iv) its performance track
record; and (v) other factors deemed relevant. The Trustees also reviewed the
fees to be paid to each Sub-adviser.

These financial service companies act as Investment Sub-advisers through an
agreement each entered into with VALIC. For more information on these agreements
and on these Sub-advisers, see the "Investment Sub-Advisers" section in the
Statement of Additional Information.
 
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.

The Investment Advisory Agreement we entered into with each Fund does not limit
how much the Funds pay in monthly expenses each year.
 
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.
 
  From time to time VALIC, the Sub-adviser and/or the Distributor may
voluntarily undertake to reduce a Fund's expenses by reducing the fees payable
to them to the extent of, or bearing expenses in excess of, such limitations as
they may establish.
 
                                                                               7

THE SUB-ADVISERS
 
The Funds do not pay the Sub-advisers directly. According to the agreements
VALIC pays them a fee based on the Fund's average monthly net asset value. 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 terminate,
replace or add Sub-advisers and to enter into sub-advisory agreements with Sub-
advisers upon approval of the Broad 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

0.03%.

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

pay Capital Guardian a quarterly 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 all fees if total fees are between $1.25
million and $4 million, a 7.5% discount to all fees if total fees are between $4
million and $8 million, a 10% discount to all fees if total fees are between $8
million and $12 million, and a 12.5% discount to all fees if total fees exceed
$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%.

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.

Sub-Advisers" section in the Statement of Additional Information.

Under the Investment Sub-Advisory Agreement we have with State Street Global
Advisors, we pay State Street Global Advisors 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 twelve members: nine
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.
 
                                                                               9

ABOUT THE FUNDS
- --------------------------------------------------------------------------------
 
GROWTH, BALANCED, INCOME, STABILITY AND LIFESTYLE 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:
 
  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 CATEGORY
 
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.

The anticipated portfolio turnover rates for each of the Funds except the Money
Market Fund are as follows:

International Value Fund            150%
Large Cap Value Fund                100%
Mid Cap Value Fund                  100%
Small Cap Value Fund                100%
Socially Responsible Fund           120%
Balanced Fund                       150%
Domestic Bond Fund                  150%

Moderate Growth Lifestyle         10-20%
  Fund
Conservative Growth Lifestyle     10-20%
  Fund
</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.

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 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.

Jacobs Asset Management
 
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.

  *** An "emerging country" security is issued by a
      Company that in our opinion has one or more of the following
      characteristics: (i) its principal securities trading market is in an
      emerging country; (ii) alone or on a consolidated basis, it derives 50% or
      more of its annual revenue from either goods produced, sales made or
      services performed in emerging countries, or (iii) it is organized under
      the laws of, and has a principal office in, an emerging country.
 **** Small capitalization companies are companies with
      market capitalizations of less than $1 billion at the time of purchase.
***** For temporary defensive reasons, we may invest up
      to 100% of the Fund's assets in short-term (less than twelve months to
      maturity) securities or cash, including domestic and foreign money market
      instruments, certificates of deposit, bankers' acceptances, time deposits,
      U.S. Government obligations, U.S. Government agency securities, short-term
      corporate debt securities, and commercial paper rated A-1 or A-2 by S&P or
      Prime 1 or Prime 2 by Moody's or if unrated, in our opinion of comparable
      quality. We may do this when we think economic, political or market
      conditions make it too risky for us to follow our general guidelines.

INTERNATIONAL GROWTH FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
1. The Templeton Performance Information
 
The International Growth Fund commenced operations on                and has no
investment performance record. The performance information shown below is for
the Templeton International Fund, a series of the Templeton Variable Products
Series Fund, which was managed by Mr. Jacobs, a principal of the Sub-adviser.
The Templeton International Fund has substantially similar, though not
necessarily identical objectives, policies and strategies as the International
Growth Fund. The chart below shows the historical investment performance for the
year-ended June 30, 1995 and the three-years ended 1995. The inception date for
the Templeton International Fund was May 1, 1992. During Mr. Jacobs ten years as
the portfolio manager of the fund, from May 1, 1992 to June 30, 1995, he was
primarily responsible for the day-to-day management of the fund, and no other
person had a significant role in scheduling the fund's performance.
 
Distribution and advisory fees for the International Growth Fund are higher than
the distribution and advisory fees incurred by the funds comprising the
Composite. The other fees and expenses incurred by the International Growth Fund
may be higher or lower than the other fees and expenses incurred by the funds
comprising the Composite in any given year. See "Performance and Yield
Information" in the Statement of Additional Information for a description of the
manner in which performance has been calculated. THE PERFORMANCE INFORMATION
BELOW IS BASED ON A FUND COMPARABLE TO THE INTERNATIONAL GROWTH FUND AND DOES
NOT REFLECT THE PERFORMANCE OF THE FUND ITSELF.

2. The Separate Account Performance Information
 
Although the International Growth Fund has no performance record, the Fund's
investment objectives, policies and strategies will be substantially similar to
those employed by the Sub-adviser with respect to certain separately managed
accounts of 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 employs on behalf of the Fund. The Sub-adviser Composite represents
the total return, net of all fees and expenses, of all relevant separately
managed accounts of the Sub-adviser. The inception date of the Sub-adviser
Composite was October 1, 1995.
 
The separately managed accounts in the Sub-adviser Composite were 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 registered mutual funds, their performance might
have been lower.
 
Distribution and advisory fees for the International Growth Fund are higher than
the distribution and advisory fees incurred by the funds comprising the
Templeton International Fund. The other fees and expenses incurred by the
International Growth Fund may be higher or lower than the other fees and
expenses incurred by the funds comprising the Templeton International Fund in
any given year. See "Performance and Yield Information" in the Statement of
Additional Information for a description of the manner in which performance has
been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A COMPOSITE

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 commenced operations on               and has no
investment performance record. However, the Large Cap Growth Fund's investment
objectives, policies and strategies are substantially similar to the Goldman
Sachs CORE Large Cap Growth Fund and it is managed in substantially the same
manner and by the same individuals as 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 November 11, 1991
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. 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.
 
Distribution and advisory fees for the Large Cap Growth Fund are higher than the
distribution and advisory fees incurred by the Goldman Sachs CORE Large Cap
Growth Fund. The other fees and expenses incurred by the Large Cap Growth Fund
may be higher or lower than the other fees and expenses incurred by the Goldman
Sachs CORE Large Cap Growth Fund in any given year. See "Performance and Yield

INVESTMENT SUB-ADVISER
 
Brown Capital Management, Inc.
 
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.

MID CAP GROWTH FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Mid Cap Growth Fund commenced operations on               and has no
investment performance record. However, the Mid Cap Growth Fund's investment
objective, policies and strategies are 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
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 of the
discretionary investment accounts comprising the Combined Accounts Composite
range from January 1, 1993 to October 1, 1997.
 
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.
 
Distribution and advisory fees for the Mid Cap Growth Fund are higher than the
fees and expenses historically incurred by the Combined Accounts comprising the
Combined Accounts Composite. Consequently, the performance results for the
Combined Accounts Composite would have been adversely affected if the Combined
Accounts Composite had the same expenses as the Mid Cap Growth Fund. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of the manner in which performance has been calculated. THE

PORTFOLIO MANAGER
 
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
Fact Sheet
- --------------------------------------------------------------------------------
 
The Small Cap Growth Fund commenced operations on               and has no
investment performance record. However, the Small Cap Growth Fund's investment
objective, policies and strategies are 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 of the discretionary
accounts comprising the Combined Accounts Composite range from September 1, 1994
to June 1, 1997.
 
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 registered mutual funds, their
performance might have been lower.
 
Distribution and advisory fees for the Small Cap Growth Fund are higher than the
fees and expenses historically incurred by the Combined Accounts comprising the
Combined Accounts Composite. Consequently, the performance results for the
Combined Accounts Composite would have been adversely affected if the Combined
Accounts Composite had the same expenses as the Small Cap Growth Fund. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of the manner in which performance has been calculated. THE

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 commenced operations on                and has no
investment performance record. However, the International Value Fund's
investment objectives, policies and strategies are 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 dates of the discretionary accounts comprising the Sub-Adviser
Composite range from December 31, 1978 to March 31, 1998.
 
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 registered mutual funds, their performance might

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 commenced operations on               and has no
investment performance record. However, the Large Cap Value Fund will be managed
in substantially the same manner and by the same individuals as those employed
by the Sub-adviser for Discretionary Accounts (the "Discretionary Accounts")
managed by the Sub-adviser with similar investment objectives, policies and
strategies. The Discretionary Account are not subject to the same investment
limitations, diversification and restriction imposed on registered mutual funds
by the 1940 Act and the Internal Revenue Code.
 
The chart below shows the investment performance for the Discretionary Accounts.
The inception date for the Discretionary Accounts range from August 1, 1992
through August 1, 1997.
The Discretionary Accounts are not subject to the investment limitations,
diversification requirements and the other restrictions imposed on registered
mutual funds by the 1940 Act and the Internal Revenue Code. If the Discretionary
Accounts had been subject to the requirements imposed on registered mutual
funds, their performance might have been lower. Consequently, the performance
results for the Discretionary Accounts would have been adversely affected if the

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.

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.

SOCIALLY RESPONSIBLE FUND
Fact Sheet
- --------------------------------------------------------------------------------
 
The Socially Responsible Fund commenced operations              and has no
investment performance record. However, the Socially Responsible Fund's
investment objectives, policies and strategies are substantially similar to
those of the American General Series Portfolio Company Social Awareness Fund
("AGSPC Social Awareness Fund") and it is managed in substantially the same
manner and by the same individuals as AGSPC Social Awareness Fund. The chart
below shows the historical investment performance for the AGSPC Social Awareness
Fund for the period of October 2, 1989 through March 31, 1998. The inception
date for the AGSPC Social Awareness Fund was October 2, 1989.
 
Distribution and advisory fees for the Socially Responsible Fund are higher than
the distribution and advisory fees incurred by the AGSPC Social Awareness Fund.
The other fees and expenses incurred by the Socially Responsible Fund may be
higher or lower than the other fees and expenses incurred by the AGSPC Social
Awareness Fund in any given year. See "Performance and Yield Information" in the
Statement of Additional Information for a description of the manner in which
performance has been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A

PORTFOLIO MANAGERS
 
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 commenced operations on               and has no investment
performance record. However, the Balanced 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 dates of the accounts comprising
Sub-adviser Composite range from December 31, 1974 to September 30, 1997.
 
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.
 
Distribution and advisory fees for the Balanced Fund are higher than the fees
and expenses historically incurred by the accounts comprising the Sub-adviser
Composite. Consequently, the performance results for the Sub-adviser Composite
would have been adversely affected if the Sub-adviser Composite had the same
expenses as the Balanced Fund. See "Performance and Yield Information" in the

performance has been calculated. THE PERFORMANCE INFORMATION BELOW IS BASED ON A

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

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

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:
 
  B Securities issued or guaranteed by the U.S. Government, its agencies or
    instrumentalities
 
  B Certificates of deposit and other obligations of domestic banks that have
    total assets in excess of $1 billion
 
  B Commercial paper sold by corporations and finance companies
 
  B Corporate debt obligations with remaining maturities of 13 months or less
 
  B Repurchase agreements
 
  B Money market instruments of foreign issuers payable in U.S. dollars (limited
    to no more than 20% of the Fund's net assets)
 
  B Asset-backed securities
 
  B Loan participations
 
  B Adjustable rate securities
 
  B Illiquid and restricted securities (including Rule 144A Securities)*

*Limited to 10% of the Fund's net assets.

The Fund is managed by a team led by William Trimbur, Jr. Mr. Trimbur has been
this Fund's portfolio manager and Vice President and Investment Officer of the
Series Company since its inception. Since 1987, Mr. Trimbur has served as Vice
President and Investment Officer of American General Series Portfolio Company, a
registered investment company.
 
INVESTMENT OBJECTIVE
 
Seeks growth through investments in Series Company Funds. This Fund is suitable
for investors seeking the potential for capital growth that a fund investing
predominately in common stocks may offer.
 
INVESTMENT RISK
 
The Fund allocates its assets among nine of the Series Company Funds. The
allocation among the different Series Company Funds is designed to achieve the
Fund's investment objective and reduce risk.
 
The Fund's performance is directly related to the performance of the Series
Company Funds in which it invests. Changes in the net asset values of the
underlying Series Company Funds affect this Fund's net asset value. Also, the

underlying Series Company Funds to meet their investment objective.
 
Investment in the Series Company Funds involves manager risk. The securities
that Series Company Funds invest in involve market risk, credit risk, interest
rate risk and risk associated with foreign investments. For a discussion of
these risks, see "A Word About Risk" in this prospectus.

This Fund is managed so that it can serve as a complete investment program for
you or as a core part of your larger portfolio. We intend to allocate the Fund's

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>   167
- --------------------------------------------------------------------------------
 
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 Mid Cap
Value Fund may invest in EDRs and/or GDRs. The Large Cap Growth Fund may invest
in GDRs but may not invest in EDRs.

of Additional Information.

SECURITIES see the

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 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 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 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:
 
  B Cash and cash equivalents
 
  B Securities issued or guaranteed by the U.S. Government, its agencies or
    instrumentalities
 
  B Certificates of deposit and other obligations of domestic banks having total
    assets in excess of $1 billion
 
  B Commercial paper sold by corporations and finance companies
 
  B Corporate debt obligations with remaining maturities of 13 months or less
 
  B 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 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

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 Mid Cap
Growth Fund and the International Growth Fund may invest in one or more of the
following types of futures and options:
 
  B Write exchange traded covered put and call options on securities and stock
    indices.
 
  B Purchase exchange traded put and call options on securities and stock
    indices.
 
  B Purchase and sell exchange traded financial futures contracts.
 
  B Write covered call options and purchase exchange traded put and call options
    on financial futures contracts.
 
  B 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 and the Small Cap Growth 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 and the Small Cap Growth Fund are authorized to use
warrants or rights.

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.

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.
 
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 Custodians, as monitored by VALIC and authorized by
the Board of Trustees.

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 Institutional Class II
Shares of the Funds only to employee retirement plans offered through the
Distributor.
 
The Series Company was organized on March 16, 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, divided into class. Each Fund
currently offers five classes of shares, designated Class A shares, Class B
shares, Class C shares, Institutional Class I shares and Institutional Class II
shares. Other classes may be established from time to time in accordance with
provisions of the Series Company's Declaration of Trust.
 
Each class of shares represents an interest in the same assets of a Fund and
generally are identical in all respects except that each class bears certain
distribution expenses and has exclusive voting rights with respect to its
distribution fee, if any. Except as described herein, there are no conversion,
preemptive or other subscription rights. In the event of liquidation, each of
the shares of a Fund is entitled to its portion of all of the Fund's net assets
after all debts and expenses of the Fund have been paid. Since Class B and Class
C shares pay higher distribution fees and transfer agent costs, the liquidation
proceeds to Class B and Class C shareholders are likely to be lower than to
other shareholders.
 
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.
 
PURCHASE AND REDEMPTION OF SHARES
 
Institutional Class II shares of each Fund are available to you through your
employer bought from the Distributor or the Series Company through National
Financial Data Services, Inc., the Funds' transfer agent ("Transfer Agent").
Institutional Class II shares are available to any qualifying employer plan once
the plan establishes a minimum account balance of $50 million with the Series
Company. A plan's account balance is equal at any time to the aggregate of all
amounts contributed by the plan to the Series Company, less the cost of all
redemptions by such plan from the Series Company. For purposes of class
eligibility, market appreciation is considered. VALIC may waive the minimum
account balance requirement if it reasonably anticipates that the size of the
plan and/or the anticipated amount of contributions will present economies of
scale.
 
As a participant in an employer retirement plan, you do not purchase
Institutional Class II shares of the Funds directly. Rather, Institutional Class
II shares of a Fund are purchased for you when you elect to allocate your
retirement contributions to a Fund that is available as an investment option in
your retirement or savings plan. You may be permitted to elect different
investment options, alter the amounts contributed to your plan, or change how
contributions are allocated among your investment options in accordance with
your plan's specific provisions. See your plan administrator or employee
benefits office for more details.
 
As distributor, the Distributor sells Institutional Class II shares of the Funds
to employer retirement plans. The Distributor sends orders to buy, sell or
transfer shares to the Series Company's transfer agent daily. The Series Company
may suspend the sale of any of the Fund's Institutional Class II shares to
employer retirement plans.
 
The price to purchase one share of a Fund is the Fund's net asset value per
share (NAV). Shares are sold at the public offering price based on the net asset
value next determined after the Transfer Agent receives an order. In most cases,
in order to receive that day's public offering price, the Transfer Agent must
receive an order, either directly or from the Distributor, before the close of
regular trading on the New York Stock Exchange.
 
The Distributor is a wholly-owned subsidiary of VALIC and acts as distributor of
the Funds' shares under an agreement with the Series Company. The Distributor
does not charge the Series Company or employer retirement plans for its
services. Also, the Distributor is not required

to sell a minimum number of shares to employer retirement plans.
 
For more information on how to participate in the Funds through an employee
retirement plan, please refer to your plan materials or contact your employee
benefits office.
 
TRANSFERS AND EXCHANGES
 
An employer retirement plan may allow you to exchange all or part of your
existing plan balance from one investment option to another. Check with your
plan administrator for details on the rules governing exchanges in your plan.
Certain investment options, particularly company stock or guaranteed investment
contracts (GICs), may be subject to unique restrictions. Exchanges will be
accepted by the Series Company only as permitted by your plan. Your plan
administrator can explain how frequently exchanges are allowed. The Series
Company reserves the right to refuse any exchange purchase request.
 
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 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 the Distributor, an employer plan sends 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. The Money
Market Fund pays dividends daily, the International Growth Fund, the Large Cap
Value Fund and the Small Cap Value Fund pay dividends quarterly and all other
Funds pay dividends once a month.
 
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 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
 
See the Statement of Additional information and your contract prospectus for
further tax discussions. You should also consult your tax advisor before
investing.
 
 48
<PAGE>   174
 
- --------------------------------------------------------------------------------
 
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 under an employer plan, you vote on these matters indirectly by
voting your shares. The way you vote your shares as a participant depends on
your employer plan.
 
When a matter comes up for vote, the employer plan will vote its shares in the
same proportion as the share 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 shares, it may decide to vote that way.
 
Controlling Shareholder
 
[VALIC,] as the initial sole shareholder 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.
 
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 participants or other investors. 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 2 (the "Series Company") was
organized as a Delaware business trust on March 16, 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 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 Funds have not commenced operations and, therefore, have no
performance. Accordingly, the performance information for each Fund included in
the prospectus is the performance of either: (i) a registered investment company
with similar investment objectives, policies and strategies as the Fund that is
managed by the same individuals; (ii) an unregistered discretionary account of a
Sub-adviser with similar investment objectives, policies and strategies as a
Fund that is managed by the same individuals; and/or (iii) a composite of
registered management investment companies or unregistered discretionary
accounts.
 
     The total return of a Fund ("Average Annual Total Return"), is the 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"), if any. 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 calcu-
                                        4
<PAGE>   183
 
lated by adding to the Average Total Annual Return (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
 
                                        8
<PAGE>   187
 
     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.

 (2) Pledge, mortgage or hypothecate for any purpose in excess of 10% of the
     Fund total assets (taken at market value), provided that collateral

     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

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

     Trustees.
 
 (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
 
                                        9
<PAGE>   188
 
     securities of such issuer, for which purposes all indebtedness of an issuer

     issuer any of whose officers, directors, trustees or security holders is an

(12) Invest more than 5% of the Fund's net assets in warrants (valued at the
     lower of cost or market) (other than warrants acquired by the Fund as part

     times when a short position is open, it owns an equal amount of such
     securities or securities convertible into or exchangeable without payment

     amount to, the securities sold short and unless not more than 10% of the

     thereby extinguishing the Fund's obligation to deliver securities pursuant
     to the call it has sold: and (d) at the time a put is written, the Fund
     establishes a segregated account with its custodian consisting of cash or
     short-term U.S. government securities equal in value to the amount the Fund

     assets. The Fund may mortgage, pledge or hypothecate more than 5% of the
     value of its total assets, and then only to secure borrowings made under

     the Fund. Additionally, investment company securities will only be
     purchased on the open market or from brokers or dealers receiving customary
     commissions.

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

 (7) Effect short sales of securities or purchase securities on margin, except

     up to 30% of the value of the Fund's total assets.

     otherwise) or acquire any options thereon, if, immediately thereafter, the
     total of the initial margin deposits required with respect to all open
     futures positions, at the time such positions were established, plus the
     sum of the premiums paid for all unexpired options on futures contracts
     would exceed 5% of the value of its total assets.
 
(12) Invest more than 25% of the value of its total assets in the securities of
     issuers primarily engaged in any one industry.

 (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.

     default as to interest or principal; and (ii) is rated in one of the two

     preferred stock of an issuer shall be deemed a single class, except that

     the put (this account must be maintained until the put is exercised, has
     expired, or the Fund has purchased a closing put, which is a put of the
     same series as the one previously written).

     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

     temporary or emergency purposes and not for leveraging or investment and
     (ii) enter into reverse repurchase agreements for any purpose; provided
     that (i) and (ii) in combination do not exceed 33 1/3% of the value of its
     total assets (including the amount borrowed) less liabilities (other than

     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

     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
 
                                       19
<PAGE>   198
 
     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

     securities or (ii) by engaging in repurchase agreements.

     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.

 (9) Purchase securities if outstanding borrowings, including any reverse
     repurchase agreements, exceed 5% of its total assets.
 
(10) Except for the purchase of debt securities and engaging in repurchase
     agreements, make any loans other than securities loans.
 
(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,

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.

<PAGE>   199
 
(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.

     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

     the lesser of 2.0% of the value of the Fund's net assets or 2.0% of the
     securities of any class of
                                       21
<PAGE>   200
 
     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

     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

     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
     preferred stock of an issuer shall be deemed a single class, except that

     more of such persons owns beneficially more than 1/2 of 1% of the shares or
     securities, or both, all taken at market value, of such issuer, and such
     persons owning more than 1/2 of 1% of such shares or securities together

     taken at market value.
 
(12) Invest in warrants (other than warrants acquired by the Fund as part of a
     unit or attached to securities at the time of purchase) if, as a result,
     the investments (valued at the lower of cost or market) would exceed 5% of

     applicable state securities laws.

     Fund has purchased a closing call, and such purchase has been confirmed,
     thereby extinguishing the Fund's obligation to deliver securities pursu-
 
                                       22
<PAGE>   201

     will be obligated to pay upon exercise of the put (this account must be
     maintained until the put is exercised, has expired, or the Fund has
     purchased a closing put, which is a put of the same series as the one
     previously written).

     securities, or any other class of securities, of any one issuer. For
     purposes of this restriction, all outstanding debt securities of an issuer
     are considered as one class, and all preferred stock of an issuer is

<PAGE>   207
 
                              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 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 pass to the borrower, the lending Fund
will call the
                                       29
<PAGE>   208
 
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
 
                                       30
<PAGE>   209
 
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 Index
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
 
                                       31
<PAGE>   210
 
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.
 
                                       32
<PAGE>   211
 
     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
                                       33
<PAGE>   212
 
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
                                       34
<PAGE>   213
 
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.
 
                                       35
<PAGE>   214
 
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
                                       36
<PAGE>   215
 
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
                                       37
<PAGE>   216
 
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-
                                       38
<PAGE>   217
 
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-

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,
 
                                       40
<PAGE>   219
 
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
 
                                       41
<PAGE>   220
 
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
                                       42
<PAGE>   221
 
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
 
                                       43
<PAGE>   222
 
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
                                       44
<PAGE>   223
 
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 VALIC to terminate, 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-
                                       45
<PAGE>   224
 
vision and direction, the Sub-advisers will manage the investment and
reinvestment of the assets, other than cash, 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.
 
     VALIC shall pay to Bankers Trust, for the services rendered and expenses
paid by Bankers Trust, a monthly fee computed at the annual rate of 0.03% of the

     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 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
 
                                       47
<PAGE>   226
 
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 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
 
GENERAL
 
     Pursuant to a distribution agreement, VALIC Investment Services Company
(the "Distributor") acts without remuneration as the Series Company's agent in
the distribution of Fund Shares to the public and to employee retirement plans
under a distribution agreement. The Distributor's address is the same as that of
VALIC.
 
     The distribution agreement between the Distributor 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 the Distributor, 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 the Distributor 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 the Distributor for
these expenses. Thus all such expenses incurred by the Distributor 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.
 
     The following information supplements the section in the Series Company's
Prospectus captioned "About the Series Company -- Purchases and Redemptions of
Shares."
 
PURCHASE OF SHARES
 
     Shares of the Funds are sold in a continuous offering and may be purchased
on any business day through authorized dealers.
 
CUMULATIVE PURCHASE DISCOUNT
 
     The reduced sales charges described in the Prospectus under "Purchases and
Redemptions of Shares -- General" apply to purchases of Class A shares of the
Fund where the aggregate investment is $50,000 or more. For purposes of
determining eligibility for volume discounts, spouses and their children under
21 years of age are treated as a single purchaser, as is a trustee or other
fiduciary of a single trust estate or a single fiduciary account. An aggregate
investment includes all shares of the Series Company Funds owned plus the shares
being purchased. The current offering price is used to determine the value of
all such shares. The same reduction is applicable to purchases under a Letter of
Intent as described in the next paragraph. The reduced sales charge will also
not be applied should a review of the records of the VISCO or Boston Data
Financial Services, the Funds' transfer agent the ("Transfer Agent"), fail to
confirm the representations concerning the investor's holdings.
 
LETTER OF INTENT
 
     Purchases of Class A shares of the Funds described above under "Cumulative
Purchase Discount" made pursuant to the Letter of Intent and still owned are
also included in determining the applicable quantity discount. A Letter of
Intent permits an investor to establish a total investment goal to be achieved
by any number of investments over a thirteen-month period. Each investment made
during the period will receive the reduced sales charge applicable to the amount
represented by the goal as if it were a single investment. Escrowed shares
totalling 5% of the dollar amount of the Letter of Intent are held by the
Transfer Agent in the name of the shareholder. The effective date of a Letter of
Intent may be back-dated up to 90 days in order that any investments made during
this
 
                                       49
<PAGE>   228
 
90-day period, valued at the investor's cost, can become subject to the Letter
of Intent. The Letter of Intent does not obligate the investor to purchase the
indicated amount. In the event the Letter of Intent goal is not achieved within
the thirteen-month period, the investor is required to pay the difference
between sales charges otherwise applicable to the purchases made during this
period and sales charges actually paid. Such payment may be made directly to the
Distributor or, if not paid, the Distributor will liquidate sufficient escrowed
shares to obtain such difference. If the goal is exceeded in an amount which
qualifies for a lower sales charge, a price adjustment is made by refunding to
the investor in shares of a Fund, the amount of excess sales charges, if any,
paid during the thirteen-month period.
 
REDEMPTION OF SHARES
 
     Redemptions are not made on days during which the Exchange is closed. The
right of redemption may be suspended and the payment therefor may be postponed
for more than seven days during any period when (a) the Exchange is closed for
other than customary weekend or holidays; (b) trading on the Exchange is
restricted; (c) an emergency exists as a result of which disposal by a Fund of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for a Fund to fairly determine the value of its net assets; or (d)
the SEC, by order, so permits.
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS A
 
     For investments of [$1,000,000] or more of Class A shares of a Fund
("Qualified Purchaser"), the front-end sales charge will be waived and a
contingent deferred sales charge ("CDSC -- Class A") of 1.00% is imposed in the
event of certain redemptions within one year of the purchase. If a CDSC -- Class
A is imposed upon redemption, the amount of the CDSC -- Class A will be equal to
the lesser of 1.00% of the net asset value of the shares at the time of purchase
or 1.00% of the net asset value of the shares at the time of redemption.
 
     The CDSC -- Class A will be imposed only if a Qualified Purchaser redeems
an amount which causes the value of the account to fall below the total dollar
amount of purchase payments made by the Qualified Purchaser without an initial
sales charge during the one-year period prior to the redemption. No
CDSC -- Class A will be imposed on exchanges between Funds. For purposes of the
CDSC -- Class A, when shares of one Fund are exchanged for shares of another
Fund, the purchase date for the shares of the Fund exchanged into will be
assumed to be the date on which shares were purchased in the Fund from which the
exchange was made. If the exchanged shares themselves are acquired through an
exchange, the purchase date is assumed to carry over from the date of the
original election to purchase shares subject to a CDSC -- Class A rather than a
front-end load sales charge. In determining whether a CDSC -- Class A is
payable, it is assumed that shares held the longest are the first to be
redeemed.
 
     Cumulative Purchase Discounts and Letters of Intent apply to the net asset
value privilege. Also, in order to establish an amount of [$1,000,000] or more,
a Qualified Purchaser may aggregate shares of a Fund described in the
Prospectus.
 
WAIVER OF CLASS B AND CLASS C CONTINGENT
DEFERRED SALES CHARGE ("CDSC -- CLASS B
AND C")
 
     As described in the Prospectus under "About the Series Company -- Purchases
and Redemptions of Shares", redemptions of Class B shares and Class C shares
will be subject to a CDSC. The CDSC -- Class B and C is waived on redemptions of
Class B shares and Class C shares in the circumstances described below.
 
     (a) Redemption Upon Disability or Death
 
     The Funds will waive the CDSC -- Class B and C on redemptions following the
death or disability of a Class B shareholder and Class C shareholder. An
individual will be considered disabled for this purpose if he or she meets the
definition thereof in Section 72(m)(7) of the Internal Revenue Code of 1986, as
amended (the "Code"), which, in pertinent part, defines a person as disabled if
such person "is unable to engage in any substantial gainful activity by reason
of any medically determinable physical or mental impairment which can be
expected to result in death or to be of long-continued and indefinite duration."
While a Fund does not specifically adopt the balance of the Code's definition
which pertains to furnishing the Secretary of Treasury with such proof as he or
she may require VISCO will require satisfactory proof of death or disability
before it determines to waive the CDSC -- Class B and C.
 
                                       50
<PAGE>   229
 
     In cases of disability or death, the CDSC -- Class B and C will be waived
where the decedent or disabled person is either an individual shareholder or
owns the shares as a joint tenant with right of survivorship or is the
beneficial owner of a custodial or fiduciary account, and where the redemption
is made within one year of the death or initial determination of disability.
This waiver of the CDSC -- Class B and C applies to a total or partial
redemption, but only to redemptions of shares held at the time of the death or
initial determination of disability.
 
     (b) Redemption in Connection with Certain Distributions from Retirement
Plans
 
     The Funds will waive the CDSC -- Class B and C when a total or partial
redemption is made in connection with certain distributions from Retirement
Plans. The charge will be waived upon the tax-free rollover or transfer of
assets to another Retirement Plan invested in one or more Funds, in such event,
as described below, the Fund will "tack" the period for which the original
shares were held onto the holding period of the shares acquired in the transfer
or rollover for purposes of determining what, if any, CDSC -- Class B and C is
applicable in the event that such acquired shares are redeemed following the
transfer or rollover. The charge will be waived on any redemption which results
from the return of an excess contribution pursuant to Section 408(d)(4) or (5)
of the Code, the return of excess deferral amounts pursuant to Code Section
401(k)(8) or 402(g)(2), or from the death or disability of the employee (see
Code Section 72(m)(7) and 72(t)(2)(A)(ii)). In addition, the charge will be
waived on any minimum distribution required to be distributed in accordance with
Code Section 401(a)(9).
 
     The Funds do not intend to waive the CDSC -- Class B and C for any
distributions from IRAs or other Retirement Plans not specifically described
above.
 
     (c) Redemption Pursuant to a Fund's Systematic Withdrawal Plan
 
     A shareholder may elect to participate in a systematic withdrawal plan (the
"Plan") with respect to the shareholder's investment in the Fund. Under the
Plan, a dollar amount of a participating shareholder's investment in a Fund will
be redeemed systematically by a Fund on a periodic basis, and the proceeds
mailed to the shareholder. The amount to be redeemed and frequency of the
systematic withdrawals will be specified by the shareholder upon his or her
election to participate in the Plan. The CDSC -- Class B and C will be waived on
redemptions made under the Plan.
 
     The amount of the shareholder's investment in a Fund at the time the
election to participate in the Plan is made with respect to a Fund is
hereinafter referred to as the "initial account balance." The amount to be
systematically redeemed from a Fund without the imposition of a CDSC -- Class B
and C may not exceed a maximum of 12% annually of the shareholder's initial
account balance. The Funds reserve the right to change the term and conditions
of the Plan and the ability to offer the Plan.
 
     (d) Involuntary Redemptions of Shares in Accounts that Do Not Have the
Required Minimum Balance
 
     The Funds reserve the right to redeem shareholder accounts with balances of
less than a specified dollar amount as set forth in the Prospectus. Prior to
such redemptions, shareholders will be notified in writing and allowed a
specified period of time to purchase additional shares to bring the account up
to the required minimum balance. The Funds will waive the CDSC -- Class B and C
upon such involuntary redemption.
 
     (e) Reinvestment of Redemption Proceeds in Shares of the Same Fund Within
120 Days After Redemption
 
     A shareholder who has a redeemed Class C shares of a Fund may reinvest at
net asset value, with credit for any CDSC -- Class C paid on the redeemed
shares, any portion or all of his or her redemption proceeds (plus that amount
necessary to acquire a fractional share to round off his or her purchase to the
nearest full share) in Class C shares of a Fund, provided that the reinvestment
is effected within 120 days after such redemption and the shareholder has not
previously exercised this reinvestment privilege with respect to Class C shares
of the Fund. Shares acquired in this manner will be deemed to have the original
cost and purchase date of the redeemed shares for purposes of applying the
CDSC -- Class C to subsequent redemptions.
 
     (f) Redemption by Adviser
 
     The Funds may waive the CDSC -- Class B and C when a total or partial
redemption is made by VALIC with respect to its investments in a Fund.]
 
                                       51
<PAGE>   230
 
EXCHANGE PRIVILEGE
 
     The following supplements the discussion of "Shareholder
Services -- Exchange Privilege" in the Prospectus:
 
     By use of the exchange privilege, the investor authorizes the Transfer
Agent to act on telephonic, telegraphic or written exchange instructions from
any person representing himself to be the investor or the agent of the investor
and believed by the Transfer Agent to be genuine. The Series Company, the
Distributor and the Transfer Agent employ procedures considered by them to be
reasonable to confirm that instructions communicated by telephone are genuine.
Such procedures include requiring certain personal identification information
prior to acting upon telephone instructions, tape recording telephone
communications, and providing written confirmation of instructions communicated
by telephone. If reasonable procedures are employed, neither the Series Company,
the Distributor nor the Transfer Agent will be liable for following telephone
instructions which it reasonably believes to be genuine. The Series Company, the
Distributor and the Transfer Agent may be liable for any losses due to
unauthorized or fraudulent instructions if reasonable procedures are not
followed.
 
     For purposes of determining the sales charge rate previously paid on Class
A shares, all sales charges paid on the exchanged security and on any security
previously exchanged for such security or for any of its predecessors shall be
included. If the exchanged security was acquired through reinvestment, that
security is deemed to have been sold with a sales charge rate equal to the rate
previously paid on the security on which the dividend or distribution was paid.
If a shareholder exchanges less than all of his securities, the security upon
which the highest sale charge rate was previously paid is deemed exchanged
first.
 
     Exchange requests received on a business day prior to the time shares of
the Funds involved in the request are priced will be processed on the date of
receipt. "Processing" a request means that shares in the Fund from which the
shareholder is withdrawing an investment will be redeemed at the net asset value
per share next determined on the date of receipt. Shares of the new Fund into
which the shareholder is investing will also normally be purchased at the net
asset value per share, plus any applicable sales charge, next determined on the
date of receipt. Exchange requests received on a business day after the time
shares of the Funds involved in the request are priced will be processed on the
next business day in the manner described herein.
 
     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 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.
 
                         DISTRIBUTION AND SERVICE PLANS
 
     The Series Company, with respect to each Fund, has adopted a Distribution
and Service Plan for Class A shares, Class B shares and Class C shares. The
Distribution and Service Plan is referred to herein as the "Plan". The Plan
provides that the Fund may spend a portion of the Fund's average daily net
assets attributable to each class of shares in connection with the provision of
ongoing services to shareholders of such class, respectively, and, with respect
to Class B shares and Class C shares in connection with distribution of the
respective class of shares. The Plan is being implemented through an agreement
with the Distributor, the distributor of the Funds' shares.
 
     Under the Plan, the Distributor must submit quarterly reports to the Board
of Trustees of the Series Company, setting forth separately by Fund and class of
shares all amounts paid under the Plan
 
                                       52
<PAGE>   231
 
and the purposes for which such expenditures were made, together with such other
information as from time to time is reasonably requested by the Trustees. The
Plan provides that they will continue in full force and effect from year to year
so long as such continuance is specifically approved by a vote of the Trustees,
and also by a vote of the disinterested Trustees, cast in person at a meeting
called for the purpose of voting on the Plan. The Plan may not be amended to
increase materially the amount to be spent for the services described therein
with respect to any class of shares without approval by a vote of a majority of
the outstanding voting shares of such class, and all material amendments to the
Plan must be approved by the Trustees and also by the disinterested Trustees.
The Plan may be terminated with respect to any class of shares at any time by a
vote of a majority of the disinterested Trustees or by a vote of a majority of
the outstanding voting shares of such class.
 
                        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
 
                                       53
<PAGE>   232
 
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
contracts) 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
                                       54
<PAGE>   233
 
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 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 taxa-
                                       55
<PAGE>   234
 
ble 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 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
distribu-
 
                                       56
<PAGE>   235
 
tions 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 derivatives 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 particu-
                                       57
<PAGE>   236
 
lar 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 proportionate
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.
 
TAXABLE U.S. SHAREHOLDERS -- DISTRIBUTIONS
 
     For U.S. federal income tax purposes, distributions by a Fund, whether
reinvested in additional shares or paid in cash, generally will be taxable to
shareholders who are subject to tax. Shareholders receiving a distribution in
the form of newly issued shares will be treated for U.S. federal income tax
purposes as receiving a distribution in an amount equal to the amount of cash
they would have received had they elected to receive cash and will have a cost
basis in each share received equal to such amount divided by the number of
shares received.
 
     Distributions from investment company taxable income for the year will be
taxable as ordinary income. Distributions designated as derived from a Fund's
dividend income, if any, that would be eligible for the dividends received
deduction if such Fund were not a regulated investment company may be eligible,
for the dividends-received deduction for corporations. The dividends-received
deduction, if available, is reduced to the extent the shares with respect to
which the dividends are received are treated as debt-financed under federal
income tax law and is eliminated if the shares are deemed to have been held for
less than a minimum period, generally 46 days. Because eligible dividends are
limited to those a Fund receives from U.S. domestic corporations, it is unlikely
that a substantial portion of the distributions made by certain Funds will
qualify for the dividends-received deduction. The entire dividend, including the
deducted amount, is considered in determining the excess, if any, of a
corporation shareholder's adjusted current earnings over its alternative minimum
taxable income, which may increase its liability for the federal alternative
minimum tax, and the dividend may, if it is treated as an "extraordinary
dividend" under the Code, reduce such shareholder's tax basis in its shares of a
Fund. Capital gain dividends (i.e., dividends from
 
                                       58
<PAGE>   237
 
net capital gain) if designated as such in a written notice to shareholders
mailed not later than 60 days after a Fund's taxable year closes, will be taxed
to shareholders as long-term capital gain regardless of how long shares have
been held by shareholders, but are not eligible for the dividends-received
deduction for corporations. For an individual, a capital gains dividend may be
further designated as gain from sale of an asset held for more than eighteen
months (thus eligible to be taxed at 10% or 20%, depending on the shareholders
marginal tax rate). Capital gains dividends not described in the previous
sentence will generally be taxed at the maximum rate of 28%, or at the
shareholder's marginal federal tax rate, whichever is less. Distributions, if
any, that are in excess of a Fund's current and accumulated earnings and profits
will first reduce a shareholder's tax basis in his shares and, after such basis
is reduced to zero, will generally constitute capital gains to a shareholder who
holds his shares as capital assets.
 
     Different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions, and certain prohibited transactions is accorded to accounts
maintained as qualified retirement plans. Distributions from such plans, or from
annuity contracts which may invest in these shares, are generally tax reported
to the participant as ordinary income taxable at the participant's marginal tax
rate for the year of the distribution to the participant, rather than as capital
gains or losses for the year of the sale or other disposition.
 
TAXABLE U.S. SHAREHOLDERS -- SALES OF SHARES
 
     When a shareholder sells, redeems or otherwise disposes of a share in a
transaction that is treated as a sale for tax purposes, the shareholder will
generally recognize gain or loss equal to the difference between the
shareholder's adjusted tax basis in the shares and the cash, or fair market
value of any property, received. Assuming that an individual shareholder holds
the shares as a capital asset at the time of such sale, the treatment of the
gain or loss may vary, depending upon the tax holding period for the shares. The
rules that individuals can use to determine the status of the gain or loss, and
to net gains and losses, are complex. In general, gain is short term gain for an
individual and is taxed at ordinary income rates, for federal income tax
purposes, if the tax holding period is less than one year. Gain is generally
mid-term gain for an individual, and taxed at a maximum rate of 28% (or the
shareholders marginal federal income tax rate, if less), if the tax holding
period is more than one year but not more than eighteen months. If the tax
holding period is more than eighteen months, the gain is generally eligible for
the most favorable treatment, and is taxed at either 20% or 10%, depending on
the individual shareholder's marginal income tax rate. Shareholders should
consult their own tax advisers with reference to their particular circumstances
to determine whether a redemption (including an exchange) or other disposition
of Fund shares is properly treated as a sale for tax purposes, as is assumed in
this discussion. If a shareholder receives a capital gain dividend with respect
to shares and such shares have a tax holding period of six months or less at the
time of a sale or redemption of such shares, then any loss the shareholder
realizes on the sale or redemption will be treated as a long-term capital loss
to the extent of such capital gain dividend. All or a portion of any sales load
paid upon the purchase of shares of a Fund will not be taken into account in
determining gain or loss on the redemption or exchange of such shares within 90
days after their purchase to the extent the redemption proceeds are reinvested,
or the exchange is effected, without payment of an additional sales load
pursuant to the reinvestment or exchange privilege. The load not taken into
account will be added to the tax basis of the newly-acquired shares.
Additionally, any loss realized on a sale or redemption of shares of a Fund may
be disallowed under "wash sale" rules to the extent the shares disposed of are
replaced with other shares of the same Fund within a period of 61 days beginning
30 days before and ending 30 days after the shares are disposed of, such as
pursuant to a dividend reinvestment in shares of such Fund. If disallowed, the
loss will be reflected in an adjustment to the basis of the shares acquired.
 
     Each Fund may be required to withhold, as "backup withholding," federal
income tax at a rate of 31% from dividends (including capital gain dividends)
and share redemption and exchange proceeds to individuals and other non-exempt
shareholders who fail to furnish such Fund with a correct taxpayer
identification number ("TIN") certified under penalties of perjury, or if the
Internal Revenue Service or a broker notifies the Fund that the payee is subject
to backup withholding as a result of failing to properly report interest or
dividend income to the Internal Revenue Service or
                                       59
<PAGE>   238
 
that the TIN furnished by the payee to be the Fund is incorrect, or if (when
required to do so) the payee fails to certify under penalties of perjury that it
is not subject to backup withholding. A Fund may refuse to accept an application
that does not contain any required TIN or certification that the TIN provided is
correct. If the backup withholding provisions are applicable, any such dividends
and proceeds, whether paid in cash or reinvested in additional shares, will be
reduced by the amounts required to be withheld. Any amounts withheld may be
credited against a shareholders' U.S. federal income tax liability.
 
     Different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions, and certain prohibited transactions is accorded to accounts
maintained as qualified retirement plans. Shareholders should consult their tax
advisers for more information.
 
NON-U.S. SHAREHOLDERS
 
     The discussion above relates solely to U.S. federal income tax law as it
applies to "U.S. persons" subject to tax under such law. Shareholders who, as to
the United States, are not "U.S. persons," (i.e., are nonresident aliens,
foreign corporations, fiduciaries of foreign trusts or estates, foreign
partnerships or other non-U.S. investors) generally will be subject to U.S.
federal withholding tax at the rate of 30% on distributions treated as ordinary
income unless the tax is reduced or eliminated pursuant to a tax treaty or the
dividends are effectively connected with a U.S. trade or business of the
shareholder. In the latter case, the dividends will be subject to tax on a net
income basis at the graduated rates applicable to U.S. individuals or domestic
corporations. Distributions of net capital gain, including amounts retained by a
Fund which are designated as undistributed capital gains, to a non-U.S.
shareholder will not be subject to U.S. federal income or withholding tax unless
the distributions are effectively connected with the shareholder's trade or
business in the United States or, in the case of a shareholder who is a
nonresident alien individual, the shareholder is present in the United States
for 183 days or more during the taxable year and certain other conditions are
met. Non-U.S. shareholders may also be subject to U.S. federal withholding tax
on deemed income resulting from any election by a Fund to treat qualified
foreign taxes it pays as passed through to shareholders (as described above),
but they may not be able to claim a U.S. tax credit or deduction with respect to
such taxes.
 
     Any capital gain realized by a non-U.S. shareholder upon a sale or
redemption of shares of a Fund will not be subject to U.S. federal income or
withholding tax unless the gain is effectively connected with the shareholders
trade or business in the U.S., or in the case of a shareholder who is a
nonresident alien individual, the shareholder is present in the U.S. for 183
days or more during the taxable year and certain other conditions are met.
 
     Non-U.S. persons who fail to furnish a Fund with an IRS Form W-8 or an
acceptable substitute may be subject to backup withholding at the rate of 31% on
capital gain dividends and the proceeds of redemptions and exchanges. Each
shareholder who is not a U.S. person should consult his or her tax adviser
regarding the U.S. and non-U.S. tax consequences of ownership of shares of and
receipt of distributions from the Funds.
 
STATE AND LOCAL
 
     Each Fund may be subject to state or local taxes in jurisdictions in which
such Fund may be deemed to be doing business. In addition, in those states or
localities which have income tax laws, the treatment of such Fund and its
shareholders under such laws may differ from their treatment under federal
income tax laws, and investment in such Fund may have tax consequences for
shareholders different from those of a direct investment in such Fund's
portfolio securities. Shareholders should consult their own tax advisers
concerning these matters.

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 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
 
                                       61
<PAGE>   240
 
amount of such gains. Thereupon, such assets will be deposited in its general or
segregated account with the Custodian, as appropriate.

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 characteristics, 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
 
                                       63
<PAGE>   242
 
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>   251
 
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.

conduct, operate, carry on and engage in such other lawful businesses or
business activities as they shall in their sole and absolute discretion
consider to be incidental to the business of the Trust or any Series as





                                       8
<PAGE>   15
an investment company, and to exercise all powers which they shall in their
discretion consider necessary, useful or appropriate to carry on the business
of the Trust or any Series, to promote any of the purposes for which the Trust
is formed, whether or not such things are specifically mentioned herein, in
order to protect or promote the interests of the Trust or any Series, or
otherwise to carry out the provisions of this Declaration.

    SECTION 3.2. Borrowings; Financings: Issuance of Securities. The Trustees
have power, subject to the fundamental policies in effect from time to time
with respect to the Trust, to borrow or in any other manner raise such sum or
sums of money, and to incur such other indebtedness for goods or services, or
for or in connection with the purchase or other acquisition of property, as
they shall deem advisable for the purposes of the Trust, in any manner and on
any terms, and to evidence the same by negotiable or nonnegotiable Securities
which may mature at any time or times, even beyond the possible date of
termination of the Trust; to issue Securities of any type for such cash,
property, services or other considerations, and at such time or times and upon
such terms, as they may deem advisable; and to reacquire any such Securities.
Any such Securities of the Trust may, at the discretion of the Trustees, be
made convertible into Shares of any Series, or may evidence the right to
purchase, subscribe for or otherwise acquire Shares of any Series, at such
times and on such terms as the Trustees may prescribe.

    SECTION 3.3. Deposits. Subject to the requirements of the 1940 Act, the
Trustees shall have power to deposit any moneys or Securities included in the
Trust Property with any one or more banks, trust companies or other banking
institutions, whether or not such deposits will draw interest. Such deposits
are to be subject to withdrawal in such manner as the Trustees may determine,
and the Trustees shall have no responsibility for any loss which may occur by
reason of the failure of the bank, trust company or other banking institution
with which any such moneys or Securities have been deposited, except as
provided in Section 8.2 hereof.

    SECTION 3.4. Allocations. The Trustees shall have power to determine
whether moneys or other assets received by the Trust shall be charged or
credited to income or capital, or allocated between income and capital,
including the power to amortize or fail to amortize any part or all of any
premium or discount, to treat any part or all of the profit resulting from the
maturity or sale of any asset, whether purchased at a premium or at a discount,
as income or capital, or to apportion the same between income and capital, to
apportion the sale price of any asset between income and capital, and to
determine in what manner any expenses or disbursements are to be borne as
between income and capital, whether or not in the absence of the power and
authority conferred by this Section 3.4 such assets would be regarded as income
or as capital or such expense or disbursement would be charged to income or to
capital; to treat any dividend or other distribution on any investment as
income or capital, or to apportion the same between income and capital; to
provide or fail to provide reserves, including reserves for depreciation,
amortization or obsolescence in respect of any Trust Property in such amounts
and by such methods as they shall determine; to allocate less than all of the
consideration paid for Shares of any Series to surplus with respect to the
Series to which such Shares relate and to allocate the balance thereof to
paid-in capital of that Series, and to reallocate such amounts from time to
time; all as the Trustees may reasonably deem proper.

      SECTION 3.5. Further Powers: Limitations. The Trustees shall have power
to do all such other matters and things, and to execute all such instruments,
as they deem necessary, proper or desirable in order to carry out, promote or
advance the interests of the Trust, although such matters or things are not
herein specifically mentioned. Any determination as to what is in the interests
of the Trust made by the Trustees in good faith shall be conclusive. In
construing the provisions of this Declaration of Trust, the presumption shall
be in favor of a grant of power to the Trustees. The Trustees shall not be
required to obtain any court order to deal with the Trust Property. The
Trustees may limit their right to exercise any of their powers through express
restrictive provisions in the instruments evidencing or providing the terms for
any Securities of the Trust or in other contractual instruments adopted on
behalf of the Trust.

                             TRUSTEES AND OFFICERS

    SECTION 4.1. Number. Designation, Election. Term, etc.

    (a) Initial Trustee. Upon his/her execution of this Agreement and
Declaration of Trust dated March 18, 1998 or a counterpart hereof or some other
writing in which he/she accepted such Trusteeship and agreed to the provisions
hereof, the individual whose signature is affixed thereto as Initial Trustee
became the Initial Trustee thereof.

    (b) Number. The Trustees serving as such, whether named above or hereafter
becoming Trustees, may increase (to not more than eight (8)) or decrease the
number of Trustees to a number other than the number theretofore determined by
a written instrument signed by a Majority of the Trustees (or by an officer of
the Trust pursuant to the vote of a Majority of the Trustees). No decrease in
the number of Trustees shall have the effect of removing any Trustee from
office prior to the expiration of his or her term, but the number of Trustees
may be decreased in conjunction with the removal of a Trustee pursuant to
Section (e) of this Section 4.1.

    (c) Election and Term. The Trustees shall be elected by the Shareholders of
the Trust at the first meeting of Shareholders immediately prior to the initial
issuance of shares of the Trust in a public offering and the term of office of
any Trustees in office before such election shall terminate at the time of such
election. Subject to Section 16(a) of the 1940 Act and to the preceding
sentence of this subsection (c) and to any requirements specified in the
By-Laws, the Trustees shall have the power to set and alter the terms of office
of the Trustees, and at any time to lengthen or shorten their own terms or make
their terms of unlimited duration, to elect their own successors and, pursuant
to subsection (f) of this Section 4.1, to appoint Trustees to fill vacancies;
provided that Trustees shall be elected by a Majority Shareholder Vote at any
such time or times as the Trustees shall determine that such action is required
under Section 16(a) of the 1940 Act or, if not so required, that such action is
advisable; and further provided that, after the initial election of Trustees by
the Shareholders, the term of office of any incumbent Trustee shall continue
until the termination of this Trust or his/her earlier death, resignation,
retirement, bankruptcy, adjudicated incompetency or other incapacity or
removal, or if not so terminated, until the election of such Trustee's
successor in office has become effective in accordance with this subsection
(c).

    (d) Resignation and Retirement. Any Trustee may resign his/her trust or
retire as a Trustee, by a written instrument signed by him/her and delivered to
the other Trustees or to any officer of the Trust, and such resignation or
retirement shall take effect upon such delivery or upon such later date as is
specified in such instrument.

    (e) Removal. Any Trustee may be removed:  (i) by vote of shareholders
holding a majority of the Shares of the Trust then outstanding, cast in person
or by proxy at any meeting called for the purpose; or (ii) by a written
declaration signed by Shareholders holding not less than a majority of the
Shares of the Trust then outstanding.

    (f) Vacancies. Any vacancy or anticipated vacancy resulting from any
reason, including an increase in the number of Trustees, may (but need not
unless required by the 1940 Act) be filled by a Majority (or a supermajority if
required by the By-Laws) of the Trustees, subject to the provisions of Section
16(a) of the 1940 Act, through the appointment in writing of such other
individual as such remaining Trustees in their discretion shall determine;
provided that if there





                                       10
<PAGE>   17
shall be no Trustees in office, such vacancy or vacancies shall be filled by
Majority Shareholders Vote. Any such appointment or election shall be effective
upon such individual's written acceptance of his/her appointment as a Trustee
and his/her agreement to be bound by the provisions of this Declaration of
Trust, except that any such appointment in anticipation of a vacancy to occur
by reason of retirement, resignation or increase in the number of Trustees to
be effective at a later date shall become effective only at or after the
effective date of said retirement, resignation or increase in the number of
Trustees.

    (g) Acceptance of Trusts. Whenever any conditions to the appointment or
election of any individual as a Trustee hereunder who was not, immediately
prior to such appointment or election, acting as a Trustee shall have been
satisfied, such individual shall become a Trustee and the Trust estate shall
vest in the new Trustee, together with the continuing Trustees, without any
further act or conveyance. Such new Trustee shall accept such appointment or
election in writing and agree in such writing to be bound by the provisions
hereof, but the execution of such writing shall not be requisite to the
effectiveness of the appointment or election of a new Trustee.

    (h) Effect of Death. Resignation, etc. No vacancy, whether resulting from
the death, resignation, retirement, bankruptcy, adjudicated incompetency,
incapacity, or removal of any Trustee, an increase in the number of Trustees or
otherwise, shall operate to annul or terminate the Trust hereunder or to revoke
or terminate any existing agency or contract created or entered into pursuant
to the terms of this Declaration of Trust. Until such vacancy is filled as
provided in this Section 4.1, the Trustees in office (if any), regardless of
their number, shall have all the powers granted to the Trustees and shall
discharge all the duties imposed upon the Trustees by this Declaration.   Upon
incapacity or death of any Trustee, his/her legal representative shall execute
and deliver on his/her behalf such documents as the remaining Trustees shall
require in order to effect the purpose of this Paragraph.

    (i) Conveyance. In the event of the resignation or removal of a Trustee or
his/her otherwise ceasing to be a Trustee, such former Trustee or his/her legal
representative shall, upon request of the continuing Trustees, execute and
deliver such documents as may be required for the purpose of consummating or
evidencing the conveyance to the Trust or the remaining Trustees of any Trust
Property held in such former Trustee's name, but the execution and delivery of
such documents shall not be requisite to the vesting of title to the Trust
Property in the remaining Trustees, as provided in subsection (g) of this
Section 4.1 and in Section 4.13 hereof.

    (j) No Accounting. Except to the extent required by the 1940 Act or under
circumstances which would justify his/her removal for cause, no Person ceasing
to be a Trustee (nor the estate of any such Person) shall be required to make
an accounting to the Shareholders or remaining Trustees upon such cessation.

    SECTION 4.2. Trustees' Meetings: Participation by Telephone. etc. Annual
and special meetings may be held from time to time, in each case, upon the call
of such officers as may be thereunto authorized by the By-Laws or vote of the
Trustees, or by any three (3) Trustees, or pursuant to a vote of the Trustees
adopted at a duly constituted meeting of the Trustees, and upon such notice as
shall be provided in the By-Laws. Any such meeting may be held within or
without the state of Delaware. The Trustees may act with or without a meeting,
and a written consent to any matter, signed by all of the Trustees, shall be
equivalent to action duly taken at a meeting of the Trustees, duly called and
held. Except as otherwise provided by the 1940 Act or other applicable law, or
by this Declaration of Trust or the By-Laws, any action to be taken by the
Trustees may be taken by a majority of the Trustees present at a meeting of
Trustees (a quorum, consisting of at least a Majority of the Trustees, being
present), within or without Delaware. If authorized by the By-Laws, all or any
one or more Trustees may participate in a meeting of the Trustees or any
Committee thereof by means of conference telephone or similar means of
communication by means of which all Persons participating in the meeting can
hear each other, and participation in a meeting pursuant to such means of
communication shall constitute





                                       11
<PAGE>   18
presence in person at such meeting. The minutes of any meeting thus held shall
be prepared in the same manner as a meeting at which all participants were
present in person.

    SECTION 4.3. Committees; Delegation. The Trustees shall have power,
consistent with their ultimate responsibility to supervise the affairs of the
Trust, to delegate from time to time to one or more other Committees, or to any
single Trustee, the doing of such things and the execution of such deeds or
other instruments, either in the name of the Trust or the names of the Trustees
or as their attorney or attorneys in fact, or otherwise as the Trustees may
from time to time deem expedient, and any agreement, deed, mortgage, lease or
other instrument or writing executed by the Trustee or Trustees or other Person
to whom such delegation was made shall be valid and binding upon the Trustees
and upon the Trust.

    SECTION 4.4. Officers. The Trustees shall annually elect such officers or
agents, who shall have such powers, duties and responsibilities as the Trustees
may deem to be advisable, and as they shall specify by resolution or in the
By-Laws. Except as may be provided in the By-Laws, any officer elected by the
Trustees may be removed at any time with or without cause. Any two (2) or more
offices may be held by the same individual.

    SECTION 4.5. Compensation of Trustees and Officers. The Trustees shall fix
the compensation of all officers and Trustees. Without limiting the generality
of any of the provisions hereof, the Trustees shall be entitled to receive
reasonable compensation for their general services as such, and to fix the
amount of such compensation, and to pay themselves or any one or more of
themselves such compensation for special services, including legal, accounting,
or other professional services, as they in good faith may deem reasonable. No
Trustee or officer resigning (except where a right to receive compensation for
a definite future period shall be expressly provided in a written agreement
with the Trust, duly approved by the Trustees) and no Trustee or officer
removed shall have any right to any compensation as such Trustee or officer for
any period following his/her resignation or removal, or any right to damages on
account of his/her removal, whether his/her compensation be by the month, or
the year or otherwise.

    SECTION 4.6. Ownership of Shares and Securities of the Trust. Any Trustee,
and any officer, employee or agent of the Trust, and any organization in which
any such Person is interested, may acquire, own, hold and dispose of Shares of
any Series and other Securities of the Trust for his/her or its individual
account, and may exercise all rights of a holder of such Shares or Securities
to the same extent and in the same manner as if such Person were not such a
Trustee, officer, employee or agent of the Trust; subject, in the case of
Trustees and officers, to the same limitations as directors or officers (as the
case may be) of a Delaware business corporation; and the Trust may issue and
sell or cause to be issued and sold and may purchase any such Shares or other
Securities from any such Person or any such organization, subject only to the
general limitations, restrictions or other provisions applicable to the sale or
purchase of Shares of such Series or other Securities of the Trust generally.

    SECTION 4.7. Right of Trustees and Officers to Own Property or to Engage in
Business; Authority of Trustees to Permit Others to Do Likewise. The Trustees,
in their capacity as Trustees, and (unless otherwise specifically directed by
vote of the Trustees) the officers of the Trust in their capacity as such,
shall not be required to devote their entire time to the business and affairs
of the Trust. Except as otherwise specifically provided by vote of the
Trustees, or by agreement in any particular case, any Trustee or officer of the
Trust may acquire, own, hold and dispose of, for his/her own individual
account, any property, and acquire, own, hold, carry on and dispose of, for
his/her own individual account, any business entity or business activity,
whether similar or dissimilar to any property or business entity or business
activity invested in or carried on by the Trust, and without first offering the
same as an investment opportunity to the Trust, and may exercise all rights in
respect thereof as if he/she were not a Trustee or officer of the Trust. The
Trustees shall also have power, generally or in specific cases, to permit
employees or agents of the Trust to have the





                                       12
<PAGE>   19
same rights (or lesser rights) to acquire, hold, own and dispose of property
and businesses, to carry on businesses, and to accept investment opportunities
without offering them to the Trust, as the Trustees have by virtue of this
Section 4.7.

    SECTION 4.8. Reliance on Experts. The Trustees and officers may consult
with counsel, engineers, brokers, appraisers, auctioneers, accountants,
investment bankers, securities analysts or other Persons (any of which may be a
firm in which one or more of the Trustees or officers is or are members or
otherwise interested) whose profession gives authority to a statement made by
them on the subject in question, and who are reasonably deemed by the Trustees
or officers in question to be competent, and the advice or opinion of such
Persons shall be full and complete personal protection to all of the Trustees
and officers in respect of any action taken or suffered by them in good faith
and in reliance on or in accordance with such advice or opinion. In discharging
their duties, Trustees and officers, when acting in good faith, may rely upon
financial statements of the Trust represented to them to be correct by any
officer of the Trust having charge of its books of account, or stated in a
written report by an independent certified public accountant fairly to present
the financial position of the Trust. The Trustees and officers may rely, and
shall be personally protected in acting, upon any instrument or other document
believed by them to be genuine.

    SECTION 4.9. Surety Bonds. No Trustee, officer, employee or agent of the
Trust shall, as such, be obligated to give any bond or surety or other security
for the performance of any of his/her duties, unless required by applicable law
or regulation, or unless the Trustees shall otherwise determine in any
particular case.

    SECTION 4.10. Apparent Authority of Trustees and Officers. No purchaser,
lender, transfer agent or other Person dealing with the Trustees or any officer
of the Trust shall be bound to make any inquiry concerning the validity of any
transaction purporting to be made by the Trustees or by such officer, or to
make inquiry concerning or be liable for the application of money or property
paid, loaned or delivered to or on the order of the Trustees or of such
officer.

    SECTION 4.11. Other Relationships Not Prohibited. The fact that:

    (i) any of the Shareholders, Trustees or officers of the Trust is a
shareholder, director, officer, partner, trustee, employee, manager, adviser,
principal underwriter or distributor or agent of or for any Contracting Party
(as defined in Section 5.2 hereof), or of or for any parent or affiliate of any
Contracting Party, or that the Contracting Party or any parent or affiliate
thereof is a Shareholder or has an interest in the Trust or any Series, or that

    (ii) any Contracting Party may have a contract providing for the rendering
of any similar services to one or more other corporations, trusts,
associations, partnerships, limited partnerships or other organizations, or
have other business or interests, shall not affect the validity of any contract
for the performance and assumption of services, duties and responsibilities to,
for or of the Trust and/or the Trustees or disqualify any Shareholder, Trustee
or officer of the Trust from voting upon or executing the same or create any
liability or accountability to the Trust or to the holders of Shares of any
Series; provided that, in the case of any relationship or interest referred to
in the preceding clause (i) on the part of any Trustee or officer of the Trust,
either (x) the material facts as to such relationship or interest have been
disclosed to or are known by the Trustees not having any such relationship or
interest and the contract involved is approved in good faith by a majority of
such Trustees not having any such relationship or interest (even though such
unrelated or disinterested Trustees are less than a quorum of all of the
Trustees), (y) the material facts as to such relationship or interest and as to
the contract have been disclosed to or are known by the Shareholders entitled
to vote thereon and the contract involved is specifically approved in good
faith by vote of the Shareholders, or (z) the specific contract involved is
fair to the Trust as of the time it is authorized, approved or ratified by the
Trustees or by the Shareholders.

    SECTION 4.12. Payment of Trust Expenses. The Trustees are authorized to pay
or to cause to be paid out of the principal or income of the Trust, or partly
out of principal and partly out of income, and according to any allocation to





                                       13
<PAGE>   20
a particular Series and Class made by them pursuant to Section 6.1(f) hereof,
all expenses, fees, charges, taxes and liabilities incurred or arising in
connection with the business and affairs of the Trust or in connection with the
management thereof, including, but not limited to, the Trustees' compensation
and such expenses and charges for the services of the Trust's officers,
employees, Investment Adviser, Administrator, Distributor, Principal
Underwriter, auditor, counsel, Custodian, Transfer Agent, Dividend Disbursing
Agent, Accounting Agent, Shareholder Servicing Agent, and such other agents,
consultants, and independent contractors and such other expenses and charges as
the Trustees may deem necessary or proper to incur.

    SECTION 4.13. Ownership of the Trust Property. Legal title to all the Trust
Property shall be vested in the Trustees as joint tenants, except that the
Trustees shall have power to cause legal title to any Trust Property to be held
by or in the name of one or more of the Trustees, or in the name of the Trust,
or of any particular Series, or in the name of any other Person as nominee, on
such terms as the Trustees may determine; provided that the interest of the
Trust and of the respective Series therein is appropriately protected. The
right, title and interest of the Trustees in the Trust Property shall vest
automatically in each Person who may hereafter become a Trustee. Upon the
termination of the term of office of a Trustee as provided in Section 4.1(c),
(d) or (e) hereof, such Trustee shall automatically cease to have any right,
title or interest in any of the Trust Property, and the right, title and
interest of such Trustee in the Trust Property shall vest automatically in the
remaining Trustees. Such vesting and cessation of title shall be effective
whether or not conveyancing documents have been executed and delivered pursuant
to Section 4.1(i) hereof.

    SECTION 4.14. By-Laws. The Trustees may adopt and from time to time amend
or repeal By-Laws for the conduct of the business of the Trust.

                                   ARTICLE 5

                   DELEGATION OF MANAGERIAL RESPONSIBILITIES

    SECTION 5.1. Appointment; Action by Less than All Trustees. The Trustees
shall be responsible for the general operating policy of the Trust and for the
general supervision of the business of the Trust conducted by officers, agents,
employees or advisers of the Trust or by independent contractors, but the
Trustees shall not be required personally to conduct all the business of the
Trust and, consistent with their ultimate responsibility as stated herein, the
Trustees may appoint, employ or contract with one or more officers, employees
and agents to conduct, manage and/or supervise the operations of the Trust, and
may grant or delegate such authority to such officers, employees and/or agents
as the Trustees may, in their sole discretion, deem to be necessary or
desirable, without regard to whether such authority is normally granted or
delegated by trustees. With respect to those matters of the operation and
business of the Trust which they shall elect to conduct themselves, except as
otherwise provided by this Declaration or the By-Laws, if any, the Trustees may
authorize any single Trustee or defined group of Trustees, or any committee
consisting of a number of Trustees less than the whole number of Trustees then
in office without specification of the particular Trustees required to be
included therein, to act for and to bind the Trust, to the same extent as the
whole number of Trustees could do, either with respect to one or more
particular matters or classes of matters, or generally.

    SECTION 5.2. Certain Contracts. Subject to compliance with the provisions
of the 1940 Act, but notwithstanding any limitations of present and future law
or custom in regard to delegation of powers by trustees generally, the Trustees
may, at any time and from time to time in their discretion and without limiting
the generality of their powers and authority otherwise set forth herein, enter
into one or more contracts with any one or more corporations, trusts,
associations, partnerships, limited partnerships or other types of
organizations, or individuals ("Contracting Party"), to provide for the
performance and assumption of some or all of the following services, duties and
responsibilities to, for





                                       14
<PAGE>   21
or on behalf of the Trust and/or any Series, and/or the Trustees, and to
provide for the performance and assumption of such other services, duties and
responsibilities in addition to those set forth below, as the Trustees may deem
appropriate:

    (a) Advisory. An investment advisory or management agreement whereby the
    agent  shall undertake to furnish the Trust (or any Series thereof) such
    management, investment advisory or supervisory, statistical and research
    facilities and services, and such other facilities and services, if any, as
    the Trustees shall from time to time consider desirable, all upon such
    terms and conditions as the Trustees may in their discretion determine to
    be not inconsistent with this Declaration, the applicable provisions of the
    1940 Act or any applicable provisions of the By-Laws (any such agent being
    herein referred to as an "Investment Adviser"). To the extent required by
    the 1940 Act, regulations or exemptions thereunder, any such advisory or
    management agreement and any amendment thereto shall be subject to approval
    by a Majority Shareholder Vote at a meeting of the Shareholders of the
    Trust (or applicable Series). Notwithstanding any provisions of this
    Declaration, the Trustees may authorize the Investment Adviser (subject to
    such general or specific instructions as the Trustees may from time to time
    adopt) to effect purchases, sales, loans or exchanges of  securities of the
    Trust on behalf of the Trustees or may authorize any officer or employee of
    the Trust or any Trustee to effect such purchases, sales, loans or
    exchanges pursuant to recommendations of the Investment Adviser (and all
    without further action by the Trustees). Any such purchases, sales, loans
    and exchanges shall be deemed to have been authorized by all of the
    Trustees. The Trustees may, in their sole discretion, call a meeting of
    Shareholders in order to submit to a vote of Shareholders of the Trust (or
    applicable Series) at such meeting the approval of continuance of any such
    investment advisory or management agreement.

    (b) Administration. An agreement whereby the agent, subject to the general
    supervision of the Trustees and in conformity with any policies of the
    Trustees with respect to the operations of the Trust and each Series
    thereof, will supervise all or any part of the operations of the Trust (or
    any Series thereof), and will provide all or any part of the administrative
    and clerical personnel, office space and office equipment and services
    appropriate for the efficient administration and operations of the Trust
    (or any Series thereof) (any such agent being herein referred to as an
    "Administrator").

    (c) Underwriting. An agreement providing for the sale of Shares of the
    Trust (or any Series thereof) to net the Trust not less than the net asset
    value per Share (as described in Section 6.1(l) hereof) and pursuant to
    which the Trust may appoint the other party to such agreement as its
    principal underwriter or sales agent for the distribution of such Shares.
    The agreement shall contain such terms and conditions as the Trustees may
    in their discretion determine to be not inconsistent with this Declaration,
    the applicable provisions of the 1940 Act and any applicable provisions of
    the By-Laws (any such agent being herein referred to as a "Distributor" or
    a "Principal Underwriter," as the case may be).

    (d) Custodian. The appointment of an agent meeting the requirements for a
    custodian for the assets of Investment Companies contained in the 1940 Act
    as custodian of the Securities and cash of the Trust (or any Series
    thereof) and of the accounting records in connection therewith (any such
    agent being herein referred to as a "Custodian").

    (e) Transfer and Dividend Disbursing Agent. An agreement with an agent to
    maintain records of the ownership of outstanding Shares, the issuance and
    redemption and the transfer thereof (any such agent  being herein referred
    to as a "Transfer Agent"), and to disburse any dividends declared by the
    Trustees and in accordance with the policies of the Trustees and/or the
    instructions of any particular Shareholder to reinvest any such dividends
    (any such agent being herein referred to as a "Dividend Disbursing Agent").





                                       15
<PAGE>   22
    (f) Shareholder Servicing. An agreement with an agent to provide service
    with respect to the relationship of the Trust and its Shareholders, records
    with respect to Shareholders and their Shares, and similar matters (any
    such agent being herein referred to as a "Shareholder Servicing Agent").

    (g) Accounting. An agreement with an agent to handle all or any part of the
    accounting responsibilities, whether with respect to the Trust's
    properties, Shareholders or otherwise (any such agent being herein referred
    to as an "Accounting Agent").

In addition, the Trustees may from time to time cause the Trust (or any Series
thereof) to enter into agreements with respect to such other services and upon
such other terms and conditions as they may deem necessary, appropriate or
desirable.  The same Person may be the Contracting Party for some or all of the
services, duties and responsibilities to, for and of the Trust and/or the
Trustees, and the contracts with respect thereto may contain such terms
interpretive of or in addition to the delineation of the services, duties and
responsibilities provided for, including provisions that are not inconsistent
with the 1940 Act relating to the standard of duty of and the rights to
indemnification of the Contracting Party and others, as the Trustees may
determine. Nothing herein shall preclude, prevent or limit the Trust or a
Contracting Party from entering into subcontractual arrangements relative to

connection with the maintenance of such shareholders' accounts.

                                   ARTICLE 6

                               SERIES AND SHARES

    SECTION 6.1. Description of Series and Shares.

    (a) General. The beneficial interest in the Trust shall be divided into
Shares (either full or fractional) with $.01 par value per Share, of which an
unlimited number may be issued. The Trustees shall have the authority from time
to time to establish and designate one or more separate, distinct and
independent Series of Shares (each of which Series shall represent interests
only in the asset attributed by the Trustees to such Series), and to authorize
separate Classes of Shares of the Trust (or any such Series), as they deem
necessary or desirable. All Shares shall be of one class, provided that the
Trustees shall have the power to classify or reclassify any unissued Shares of
any Series into any number of additional Classes of such Series.

    (b) Establishment. etc. of Series and Classes; Authorization of Shares. The
establishment and designation of any Series and the authorization of the Shares
thereof shall be effective upon the execution by a Majority of the Trustees (or
by an officer of the Trust pursuant to the vote of a Majority of the Trustees)
of an instrument setting forth such establishment and designation and the
relative rights and preferences of the Shares of such Series or Class and the
manner in which the same may be amended (a "Certificate of Designation"), and
may provide that the number of Shares of such Series or Class which may be
issued is unlimited, or may limit the number issuable. At any time that there
are no Shares outstanding of any particular Series or Class previously
established and designated, the Trustees may by an instrument executed by a
Majority of the Trustees (or by an officer of the Trust pursuant to the vote of
a Majority of





                                       16
<PAGE>   23
the Trustees) terminate such Series or Class and the establishment and
designation thereof and the authorization of its Shares (a "Certificate of
Termination"). Each Certificate of Designation, Certificate of Termination and
any instrument amending a Certificate of Designation shall have the status of
an amendment to this Declaration of Trust.

    (c) Character of Separate Series and Shares Thereof. Each Series
established hereunder shall represent  beneficial interests in a separate
component of the assets of the Trust.  Holders of Shares of a Series shall be
considered Shareholders of such Series, but such Shareholders shall also be
considered Shareholders of the Trust for purposes of receiving reports and
notices and, except as otherwise provided herein or in the Certificate of
Designation of a particular Series, or as required by the 1940 Act or other
applicable law, the right to vote, all without distinction by Series. The
Trustees shall have exclusive power without the requirement of Shareholder
approval to establish and designate such separate and distinct Series, and to
fix and determine the relative rights and preferences as between the shares of
the respective Series, and as between the Classes of  the Trust (or any Series
thereof), as to rights of redemption and the price, terms and manner of
redemption, special and relative rights as to dividends and other distributions
and on liquidation, sinking or purchase fund provisions, conversion rights, and
conditions under which the Shareholders of the several Series or the several
Classes of any Series of Shares shall have separate voting rights or no voting
rights. Except as otherwise provided as to a particular Series herein, or in
the Certificate of Designation therefor, the Trustees shall have all the rights
and powers, and be subject to all the duties and obligations, with respect to
each such Series and the assets and affairs thereof as they have under this
Declaration with respect to the Trust and the Trust Property in general.
Separate and distinct records shall be maintained for each Series of Shares and
the assets and liabilities attributable thereto.

    (d) Consideration for Shares. The Trustees may issue Shares of  the Trust
(or any Series thereof) for such consideration (which may include property
subject to, or acquired in connection with the assumption of, liabilities) and
on such terms as they may determine (or for no consideration if pursuant to a
Share dividend or split-up), all without action or approval of the
Shareholders. All Shares when so issued on the terms determined by the Trustees
shall be fully paid and nonassessable (but may be subject to mandatory
contribution back to the Trust (or applicable Series) as provided in Section
6.1(l) hereof. The Trustees may classify or reclassify any unissued Shares, or
any Shares of the Trust (or any Series thereof) previously issued and
reacquired by the Trust, into Shares of the Trust or one or more other Series
that may be established and designated from time to time.

    (e) Assets Belonging to Series.   Any portion of the Trust Property
allocated to a particular Series, and all consideration received by the Trust
for the issue or sale of Shares of such Series, together with all assets in
which such consideration is invested or reinvested, all interest, dividends,
income, earnings, profits and gains therefrom, and proceeds thereof, including
any proceeds derived from the sale, exchange or liquidation of such assets, and
any funds or payments derived from any reinvestment of such proceeds in
whatever form the same may be, shall be held by the Trustees in trust for the
benefit of the holders of Shares of that Series and shall irrevocably belong to
that Series for all purposes, and shall be so recorded upon the books of
account of the Trust, and the Shareholders of such Series shall not have, and
shall be conclusively deemed to have waived, any claims to the assets of any
Series of which they are not Shareholders. Such consideration, assets,
interest, dividends, income, earnings, profits, gains and proceeds, together
with any General Items allocated to that Series as provided in the following
sentence, are herein referred to collectively as assets "belonging to" that
Series. In the event that there are any assets, income, earnings, profits, and
proceeds thereof, funds, or payments which are not readily identifiable as
belonging to any particular Series (collectively, "General Items"), the
Trustees shall allocate such General Items to and among any one or more of the
Series established and designated from time to time in such manner and on such
basis as they, in their sole discretion, deem fair and equitable; and any
General Items so allocated to a particular Series shall belong to and be part
of the assets belonging to that Series. Each such allocation by the Trustees
shall be conclusive and binding upon the Shareholders of all Series for all
purposes.

    (f) Liabilities of Series. The assets belonging to each particular Series
shall be charged with the liabilities in respect of that Series and all
expenses, costs, charges and reserves attributable to that Series, and any
general liabilities, expenses, costs, charges or reserves of the Trust which
are not readily identifiable as pertaining to any particular Series shall be
allocated and charged by the Trustees to and among any one or more of the
Series established and designated from time to time in such manner and on such
basis as the Trustees in their sole discretion deem fair and equitable. The





                                       17
<PAGE>   24
indebtedness, expenses, costs, charges and reserves allocated and so charged to
a particular Series are herein referred to as "liabilities of" that Series.
Each allocation of liabilities, expenses, costs, charges and reserves by the
Trustees shall be conclusive and binding upon the Shareholders of all Series
for all purposes. Any creditor of any Series may look only to the assets
belonging to that Series to satisfy such creditor's debt.

    (g) Dividends. Dividends and distributions on Shares of a particular Series
may be paid with such frequency as the Trustees may determine, which may be
daily or otherwise pursuant to a standing resolution or resolutions adopted
only once or with such frequency as the Trustees may determine, to the
Shareholders of that Series, from such of the income, accrued or realized, and
capital gains, realized or unrealized, and out of the assets belonging to that
Series, as the Trustees may determine, after providing for actual and accrued
liabilities of that Series. All dividends and distributions on Shares of a
particular Series shall be distributed pro rata to the Shareholders of that
Series in proportion to the number of such Shares held by such holders at the
date and time of record established for the payment of such dividends or
distributions, except that the dividends and distributions of investment income
and capital gains with respect to each Class of Shares of a particular Series
shall be in such amount as may be declared from time to time by the Trustees,
and such dividends and distributions may vary as between such Classes to
reflect differing allocations of the expenses of the Series between the
Shareholders of such several Classes and any resultant differences between the
net asset value of such several Classes to such extent and for such purposes as
the Trustees may deem appropriate and further except that, in connection with
any dividend or distribution program or procedure, the Trustees may determine
that no dividend or distribution shall be payable on Shares as to which the
Shareholder's purchase order and/or payment have not been received by the time
or times established by the Trustees under such program or procedure, or that
dividends or distributions shall be payable on Shares which have been tendered
by the holder thereof for redemption or repurchase, but the redemption or
repurchase proceeds of which have not yet been paid to such Shareholder. Such
dividends and distributions may be made in cash, property or Shares of any
Class of that Series or a combination thereof as determined by the Trustees, or
pursuant to any program that the Trustees may have in effect at the time for
the election by each Shareholder of the mode of the making of such dividend or
distribution to that Shareholder. Any such dividend or distribution paid in
Shares will be paid at the net asset value thereof as determined in accordance
with subsection (l) of this Section 6.1.

    (h) Liquidation. In the event of the liquidation or dissolution of the
Trust (or any particular Series), the Shareholders of the Trust (or that
Series) shall be entitled to receive, when and as declared by the Trustees, the
excess of the assets belonging to the Trust (or that Series) over the
liabilities of such Series. The assets so distributable to the Shareholders of
the Trust (or that Series) shall be distributed among such Shareholders in
proportion to the number of Shares of the Trust (or that Series) held by them
and recorded on the books of the Trust.  The liquidation of the Trust (or any
particular Series) may be authorized by vote of a Majority of the Trustees,
subject to the affirmative vote of "a majority of the outstanding voting
securities" of that Series, as the quoted phrase is defined in the 1940 Act,
determined in accordance with clause (iii) of the definition of "Majority
Shareholder Vote" in Section 1.4 hereof.

    (i) Voting. The Shareholders shall have the voting rights set forth in or
determined under Article 7 hereof.

    (j) Redemption by Shareholder. Each holder of Shares of the Trust (or a
particular Series thereof) shall have the right at such times as may be
permitted by the Trust, but no less frequently than required by the 1940 Act,
to require the Trust (or such Series) to redeem all or any part of his Shares
of the Trust (or such Series) at a redemption price equal to the net asset
value per Share of the Trust (or Series) next determined in accordance with
subsection (l) of this Section 6.1 after the Shares are properly tendered for
redemption; provided, that the Trustees may from time to time, in their
discretion, determine and impose a fee for such redemption and that the
proceeds of the redemption of Shares (including a fractional Share) of any
Class of the Trust (or any Series thereof) shall be reduced by the amount of
any applicable contingent deferred sales charge or other sales charge, if any,
payable on such redemption to the distributor of Shares of such Class pursuant
to the terms of the initial issuance of the Shares of such Class (to the extent
consistent with the 1940 Act or regulations or exemptions thereunder) and the
Trust shall promptly pay to such distributor the amount of such deferred sales
charge. Payment of the redemption price shall be in cash; provided, however,
that if the Trustees determine, which determination shall be conclusive, that
conditions exist which make payment wholly in cash unwise or undesirable, the
Trust may make payment wholly or partly in Securities or other assets belonging
to such Series at





                                       18
<PAGE>   25
the value of such Securities or assets used in such determination of net asset
value. Notwithstanding the foregoing, the Trust may postpone payment of the
redemption price and may suspend the right of the holders of Shares of the Trust
(or any Series thereof) to require the Trust to redeem Shares of  the Trust (or
such Series) during any period or at any time when and to the extent permissible
under the 1940 Act.

    (k) Redemption at the Option of the Trust. The Trustees shall have the
power to redeem Shares of the Trust (or any Series thereof) at a redemption
price determined in accordance with Section 6.1(j),  if at any time (i) the
total investment in such account does not have a value of at least such minimum
amount as may be specified in the Prospectus for the Trust (or such Series)
from time to time (ii) the number of Shares held in such account is equal to or
in excess of a specified percentage of Shares of the Trust or any Series as set
forth from time to time in the applicable Prospectus. In the event the Trustees
determine to exercise their power to redeem Shares provided in this Section
6.1(k), the Shareholder shall be notified that the value of his/her account is
less than the applicable minimum amount and shall be allowed 30 days to make an
appropriate investment before redemption is processed.

    (l) Net Asset Value. The net asset value per Share of the Trust (or any
Series or Class) at any time shall be the quotient obtained by dividing the
value of the net assets of the Trust (or such Series or Class) at such time
(being the current value of the assets belonging to the Trust (or such Series
or Class), less its then existing liabilities) by the total number of Shares of
the Trust (or such Series) then outstanding, all determined in accordance with
the methods and procedures, including without limitation those with respect to
rounding, established by the Trustees from time to time in accordance with the
requirements of the 1940 Act. The net asset value of the several Classes of the
Trust (or a particular Series) shall be separately computed, and may vary from
one another. The Trustees shall establish procedures for the allocation of
investment income or capital gains and expenses and liabilities of a particular
Series between the several Classes of the Trust (or such Series).  The Trustees
may determine to maintain the net asset value per Share of the Trust or any
Series or Class at a designated constant dollar amount and in connection
therewith may adopt procedures not inconsistent with the 1940 Act for the
continuing declaration of income attributable to the Trust or such Series or
Class as dividends payable in additional Shares of the Trust or such Series or
Class at the designated constant dollar amount and for the handling of any
losses attributable to the Trust or such Series or Class. Such procedures may
provide that in the event of any loss each Shareholder shall be deemed to have
contributed to the shares of beneficial interest account of the Trust or such
Series or Class his pro rata portion of the total number of Shares required to
be canceled in order to permit the net asset value per Share of the Trust or
such Series or Class to be maintained, after reflecting such loss, at the
designated constant dollar amount. Each Shareholder of the Trust shall be
deemed to have expressly agreed, by his/her investment in the Trust (or any
Series thereof) with respect to which the Trustees shall have adopted any such
procedure, to make the contribution referred to in the preceding sentence in
the event of any such loss.

    (m) Transfer. All Shares of the Trust and each Series shall be
transferable, but transfers of Shares of  the Trust or a particular Series will
be recorded on the Share transfer records of the Trust applicable to the Trust
or such Series only at such times as Shareholders shall have the right to
require the Trust to redeem Shares of the Trust or such Series and at such
other times as may be permitted by the Trustees.

    (n) Equality. All Shares of each particular Series shall represent an equal
proportionate interest in the assets belonging to that Series (subject to the
liabilities of that Series), and each Share of any particular Series shall be
equal to each other Share thereof; but the provisions of this sentence shall
not restrict any distinctions between the several Classes of a Series
permissible under this Section 6.1 or under Section 7. 1 hereof nor any
distinctions permissible under subsection (g) of this Section 6.1 that may
exist with respect to dividends and distributions on Shares of the same Series.
The Trustees may from time to time divide or combine the Shares of any class of
particular Series into a greater or lesser number of Shares of that class of a
Series without thereby changing the proportionate beneficial interest in the
assets belonging to that Series or in any way affecting the rights of the
holders of Shares of any other Series.

    (o) Rights of Fractional Shares. Any fractional Share of the Trust (or any
Series thereof) shall carry proportionately all the rights and obligations of a
whole Share of the Trust (or such Series), including rights and obligations
with respect to voting, receipt of dividends and distributions, redemption of
Shares, and liquidation of the Trust or of the Series to which they pertain.





                                       19
<PAGE>   26
    (p) Conversion Rights.  (i) Subject to compliance with the requirements of
the 1940 Act, the Trustees shall have the authority to provide that holders of
Shares of any Series shall have the right to convert said Shares into Shares of
one or more other Series, that holders of any Class of the Trust or a Series of
Shares shall have the right to convert said Shares of such Class into Shares of
one or more other Classes of the Trust or such Series, and that Shares of any
Class of the Trust or a Series shall be automatically converted into Shares of
another Class of the Trust or such Series, in each case in accordance with such
requirements and procedures as the Trustees may establish.

    (ii) The number of Shares of into which a convertible Share shall convert
shall equal the number (including for this purpose fractions of a Share)
obtained by dividing the net asset value per Share for purposes of sales and
redemptions of the converting Share on the Conversion Date by the net asset
value per Share for purposes of sales and redemptions of the Class of Shares
into which it is converting on the Conversion Date.

    (iii) On the Conversion Date, the Share converting into another share will
cease to accrue dividends and will no longer be deemed outstanding and the
rights of the holders thereof (except the right to receive the number of target
Shares into which the converting Shares have been converted and declared but
unpaid dividends to the Conversion Date) will cease. Certificates representing
Shares resulting from the conversion need not be issued until certificates
representing Shares converted, if issued, have been received by the Trust or
its agent duly endorsed for transfer.

    (iv) The Trust will appropriately reflect the conversion of Shares of one
Class of the Trust (or a Series thereof) into Shares of another Class of the
Trust (or such Series) on the first periodic statements of account sent to
Shareholders of record affected which provide account information with respect
to a reporting period which includes the date such conversion occurred.

    SECTION 6.2. Ownership of Shares. The ownership of Shares shall be recorded
on the books of the Trust or of a Transfer Agent or similar agent for the
Trust, which books shall be maintained separately for the Shares of each Series
that has been authorized. Certificates evidencing the ownership of Shares need
not be issued except as the Trustees may otherwise determine from time to time,
and the Trustees shall have power to call outstanding Share certificates and to
replace them with book entries. The Trustees may make such rules as they
consider appropriate for the issuance of Share certificates, the use of
facsimile signatures, the transfer of Shares and similar matters. The record
books of the Trust as kept by the Trust or any Transfer Agent or similar agent,
as the case may be, shall be conclusive as to who are the Shareholders and as
to the number of Shares of the Trust and, if designated, each Series thereof
held from time to time by each such Shareholder.

    The holders of Shares of the Trust and, if designated, each Series thereof
shall upon demand disclose to the Trustees in writing such information with
respect to their direct and indirect ownership of Shares of the Trust or, if
designated, such Series as the Trustees deem necessary to comply with the
provisions of the Internal Revenue Code, or to comply with the requirements of
any other authority.

    SECTION 6.3. Investments in the Trust. The Trustees may accept investments
in any Series of the Trust from such Persons and on such terms and for such
consideration, not inconsistent with the provisions of the 1940 Act, as they
from time to time authorize. The Trustees may authorize any Distributor,
Principal Underwriter, Custodian, Transfer Agent or other Person to accept
orders for the purchase of Shares that conform to such authorized terms and to
reject any purchase orders for Shares, whether or not conforming to such
authorized terms.

    SECTION 6.4. No Preemptive Rights. No Shareholder, by virtue of holding
Shares of  the Trust or, if designated, any Series thereof, shall have any
preemptive or other right to subscribe to any additional Shares of the Trust or
such Series, or to any shares of any other Series, or any other Securities
issued by the Trust.

    SECTION 6.5. Status of Shares. Every Shareholder, by virtue of having
become a Shareholder, shall be held to have expressly assented and agreed to
the terms hereof and to have become a party hereto. Shares shall be deemed to
be personal property, giving only the rights provided herein. Ownership of
Shares shall not entitle the Shareholder to any title in or to the whole or any
part of the Trust Property or right to call for a partition or division of the
same or for an





                                       20
<PAGE>   27
accounting, nor shall the ownership of Shares constitute the Shareholders
partners. The death of a Shareholder during the continuance of the Trust shall
not operate to terminate the Trust or any Series, nor entitle the
representative of any deceased Shareholder to an accounting or to take any
action in court or elsewhere against the Trust or the Trustees, but only to the
rights of said decedent under this Declaration of Trust.



                                   ARTICLE 7

                    SHAREHOLDERS' VOTING POWERS AND MEETINGS

    SECTION 7.1. Voting Powers. The Shareholders shall have power to vote only
(i) for the election or removal of Trustees as provided in Sections 4.1(c) and
(e) hereof, (ii) with respect to the approval or termination in accordance with
the 1940 Act of any contract with a Contracting Party as provided in Section
5.2 hereof as to which Shareholder approval is required by the 1940 Act, (iii)
with respect to any termination or reorganization of the Trust or any Series to
the extent and as provided in Sections 9.2, 9.3 and 9.4 hereof, (iv) with
respect to any amendment of this Declaration of Trust to the extent and as
provided in Section 9.5 hereof, (v) to the same extent as the stockholders of a
Delaware business corporation as to whether or not a court action, proceeding
or claim should or should not be brought or maintained derivatively or as a
class action on behalf of the Trust or any Series, or the Shareholders of any
of them (provided. however, that a Shareholder of a particular Series shall not
in any event be entitled to maintain a derivative or class action on behalf of
any other Series or the Shareholders thereof), and (vi) with respect to such
additional matters relating to the Trust as may be required by the 1940 Act,
this Declaration of Trust, the By-Laws or any registration of the Trust with
the Commission (or any successor agency) or any State, or as the Trustees may
consider necessary or desirable. If and to the extent that the Trustees shall
determine that such action is required by law or by this Declaration, they
shall cause each matter required or permitted to be voted upon at a meeting or
by written consent of Shareholders to be submitted to a separate vote of the
outstanding Shares of each Series entitled to vote thereon; provided, that (i)
when expressly required by the 1940 Act or by other law, actions of
Shareholders shall be taken by Single Class Voting of all outstanding Shares
whose holders are entitled to vote thereon; and (ii) when the Trustees
determine that any matter to be submitted to a vote of Shareholders affects
only the rights or interests of Shareholders of one or more but not all Series
or of one or more but not all Classes of the Trust or a single Series
(including without limitation any distribution plan pursuant to Rule 12b-1 of
the 1940 Act applicable to such Class), then only the Shareholders of the
Series or Classes so affected shall be entitled to vote thereon. Any matter
required to be submitted to shareholders and affecting one or more Series shall
require separate approval by the required vote of Shareholders of the Trust or
each affected Series; provided, however, that to the extent required by the
1940 Act, there shall be no separate Series votes on the election or removal of
Trustees, the selection of auditors for the Trust and its Series or approval of
any agreement or contract entered into by the Trust or any Series. Shareholders
of a particular Series shall not be entitled to vote on any matter that affects
only one or more other Series.

    SECTION 7.2. Number of Votes and Manner of Voting: Proxies. On each matter
submitted to a vote of the Shareholders, each holder of Shares of the Trust or,
if applicable, any Series shall be entitled to a number of votes equal to the
number of Shares of the Trust or such Series standing in his name on the books
of the Trust. There shall be no cumulative voting in the election or removal of
Trustees. Shares may be voted in person or by proxy. A proxy with respect to
Shares held in the name of two (2) or more Persons shall be valid if executed
by any one of them unless at or prior to exercise of the proxy the Trust
receives a specific written notice to the contrary from any one of them. A
proxy purporting to be executed by or on behalf of a Shareholder shall be
deemed valid unless challenged at or prior to its exercise and the burden of
proving invalidity shall rest on the challenger. Until Shares are issued, the
Trustees may exercise all rights of Shareholders and may take any action
required by law, this Declaration of Trust or the By-Laws to be taken by
Shareholders.

    SECTION 7.3. Meetings. Meetings of Shareholders may be called by the
Trustees from time to time for the purpose of taking action upon any matter
requiring the vote or authority of the Shareholders as herein provided, or upon
any





                                       21
<PAGE>   28
other matter deemed by the Trustees to be necessary or desirable. Written
notice of any meeting of Shareholders shall be given or caused to be given by
the Trustees by mailing such notice at least seven (7) days before such
meeting, postage prepaid, stating the time, place and purpose of the meeting,
to each Shareholder at the Shareholder's address as it appears on the records
of the Trust. The Trustees shall promptly call and give notice of a meeting of
Shareholders for the purpose of voting upon removal of any Trustee of the Trust
when requested to do so in writing by Shareholders holding not less than ten
percent (10%) of the Shares then outstanding. If the Trustees shall fail to
call or give notice of any meeting of Shareholders for a period of thirty (30)
days after written application by Shareholders holding at least ten percent
(10%) of the Shares then outstanding requesting that a meeting be called for
any other purpose requiring action by the Shareholders as provided herein or in
the By-Laws, then Shareholders holding at least ten percent (10%) of the Shares
then outstanding may call and give notice of such meeting, and thereupon the
meeting shall be held in the manner provided for herein in case of call thereof
by the Trustees.   Any meetings may be held within or without The State of
Delaware.  Shareholders may only act with respect to matters set forth in the
notice to Shareholders.

    SECTION 7.4. Record Dates. For the purpose of determining the Shareholders
who are entitled to vote or act at any meeting or any adjournment thereof, or
who are entitled to participate in any dividend or distribution, or for the
purpose of any other action, the Trustees may from time to time close the
transfer books for such period, not exceeding thirty (30) days (except at or in
connection with the termination of the Trust), as the Trustees may determine;
or without closing the transfer books the Trustees may fix a date and time not
more than ninety (90) days prior to the date of any meeting of Shareholders or
other action as the date and time of record for the determination of
Shareholders entitled to vote at such meeting or any adjournment thereof or to
be treated as Shareholders of record for purposes of such other action, and any
Shareholder who was a Shareholder at the date and time so fixed shall be
entitled to vote at such meeting or any adjournment thereof or to be treated as
a Shareholder of record for purposes of such other action, even though he has
since that date and time disposed of his Shares, and no Shareholder becoming
such after that date and time shall be so entitled to vote at such meeting or
any adjournment thereof or to be treated as a Shareholder of record for
purposes of such other action.

    SECTION 7.5. Quorum and Required Vote. A majority of the Shares entitled to
vote shall be a quorum for the transaction of business at a Shareholders'
meeting, but any lesser number shall be sufficient for adjournments. Any
adjourned session or sessions may be held within a reasonable time after the
date set for the original meeting without the necessity of further notice. A
Majority Shareholder Vote at a meeting of which a quorum is present shall
decide any question, except when a different vote is required or permitted by
any provision of the 1940 Act or other applicable law or by this Declaration of
Trust or the By-Laws, or when the Trustees shall in their discretion require a
larger vote or the vote of a majority or larger fraction of the Shares of one
or more particular Series.

    SECTION 7.6. Action By Written Consent. Subject to the provisions of the
1940 Act and other applicable law, any action taken by Shareholders may be
taken without a meeting if a majority of Shareholders entitled to vote on the
matter (or such larger proportion thereof or of the Shares of any particular
Series as shall be required by the 1940 Act or by any express provision of this
Declaration of Trust or the By-Laws or as shall be permitted by the Trustees)
consent to the action in writing and if the writings in which such consent is
given are filed with the records of the meetings of Shareholders, to the same
extent and for the same period as proxies given in connection with a
Shareholders' meeting.  Such consent shall be treated for all purposes as a
vote taken at a meeting of Shareholders.

    SECTION 7.7. Inspection of Records. The records of the Trust shall be open
to inspection by Shareholders to the same extent as is permitted stockholders
of a Delaware business corporation under the Delaware business corporation law.

    SECTION 7.8. Additional Provisions. The By-Laws may include further
provisions for Shareholders' votes and meetings and related matters not
inconsistent with the provisions hereof.

    SECTION 8.1. Trustees. Shareholders. etc. Not Personally Liable; Notice.
The Trustees, officers, employees and agents of the Trust, in incurring any
debts, liabilities or obligations, or in limiting or omitting any other actions
for or in connection with the Trust, are or shall be deemed to be acting as
Trustees, officers, employees or agents of the Trust and not in their own
capacities. No Shareholder shall be subject to any personal liability
whatsoever in tort, contract or otherwise to any other Person or Persons in
connection with the assets or the affairs of the Trust or of any Series, and
subject to Section 8.4 hereof, no Trustee, officer, employee or agent of the
Trust shall be subject to any personal liability whatsoever in tort, contract,
or otherwise, to any other Person or Persons in connection with the assets or
affairs of the Trust or of any Series, save only that arising from his own
willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his office or the discharge of his functions.
The Trust (or if the matter relates only to a particular Series, that Series)
shall be solely liable for any and all debts, claims, demands, judgments,
decrees, liabilities or obligations of any and every kind, against or with
respect to the Trust or such Series in tort, contract or otherwise in
connection with the assets or the affairs of the Trust or such Series, and all
Persons dealing with the Trust or any Series shall be deemed to have agreed
that resort shall be had solely to the Trust Property of the Trust or the
Series Assets of such Series, as the case may be, for the payment or
performance thereof.

    The Trustees shall use their best efforts to ensure that every note, bond,
contract, instrument, certificate or undertaking made or issued by the Trustees
or by any officers or officer shall give notice that a Certificate of Trust in
respect of the Trust is on file with the Secretary of the state of Delaware and
shall recite to the effect that the same was executed or made by or on behalf
of the Trust or by them as Trustees or Trustee or as officers or officer, and
not individually, and that the obligations of such instrument are not binding
upon any of them or the Shareholders individually but are binding only upon the
assets and property of the Trust, or the particular Series in question, as the
case may be, but the omission thereof shall not operate to bind any Trustees or
Trustee or officers or officer or Shareholders or Shareholder individually, or
to subject the Series Assets of any Series to the obligations of any other
Series.

    SECTION 8.2. Trustees' Good Faith Action; Expert Advice: No Bond or Surety.
The exercise by the Trustees of their powers and discretions hereunder shall be
binding upon everyone interested. Subject to Section 8.4 hereof, a Trustee
shall be liable for his/her own willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of the
office of Trustee, and for nothing else, and shall not be liable for errors of
judgment or mistakes of fact or law. Subject to the foregoing, (i) the Trustees
shall not be responsible or liable in any event for any neglect or wrongdoing
of any officer, agent, employee, consultant, Investment Adviser, Administrator,
Distributor or Principal Underwriter, Custodian or Transfer Agent, Dividend
Disbursing Agent, Shareholder Servicing Agent or Accounting Agent of the Trust,
nor shall any Trustee be responsible for the act or omission of any other
Trustee; (ii) the Trustees may take advice of counsel or other experts with
respect to the meaning and operation of this Declaration of Trust and their
duties as Trustees, and shall be under no liability for any act or omission in
accordance with such advice or for failing to follow such advice; and (iii) in
discharging their duties, the Trustees, when acting in good faith, shall be
entitled to rely upon the books of account of the Trust and upon written
reports made to the Trustees by any officer appointed by them, any independent
public accountant, and (with respect to the subject matter of the contract
involved) any officer, partner or responsible employee of a Contracting Party
appointed by the Trustees pursuant to Section 5.2 hereof. The Trustees as such
shall not be required to give any bond or surety or any other security for the
performance of their duties.

    SECTION 8.3. Indemnification of Shareholders. If any Shareholder (or former
Shareholder) of the Trust shall be charged or held to be personally liable for
any obligation or liability of the Trust solely by reason of being or having
been a Shareholder and not because of such Shareholder's acts or omissions or
for some other reason, the Trust (upon proper and timely request by the
Shareholder) may assume the defense against such charge and satisfy any
judgment thereon or may reimburse the Shareholders for expenses, and the
Shareholder or former Shareholder (or the heirs, executors, administrators or
other legal representatives thereof, or in the case of a corporation or other
entity, its corporate or other general successor) shall be entitled (but solely
out of the assets of the Series of which such Shareholder or former Shareholder
is or was the holder of Shares) to be held harmless from and indemnified
against all loss and expense arising from such liability.

<PAGE>   30
    SECTION 8.4. Indemnification of Trustees. Officers, etc. Subject to the
limitations, if applicable, hereinafter set forth in this Section 8.4, the
Trust shall indemnify (from the assets of one or more Series to which the
conduct in question relates) each of its Trustees, officers, employees and
agents (including Persons who serve at the Trust's request as directors,
officers or trustees of another organization in which the Trust has any
interest as a shareholder, creditor or otherwise (hereinafter, together with
such Person's heirs, executors, administrators or personal representative,
referred to as a "Covered Person")) against all liabilities, including but not
limited to amounts paid in satisfaction of judgments, in compromise or as fines
and penalties, and expenses, including reasonable accountants' and counsel
fees, incurred by any Covered Person in connection with the defense or
disposition of any action, suit or other proceeding, whether civil or criminal,
before any court or administrative or legislative body, in which such Covered
Person may be or may have been involved as a party or otherwise or with which
such Covered Person may be or may have been threatened, while in office or
thereafter, by reason of being or having been such a Trustee or officer,
director or trustee, except with respect to any matter as to which it has been
determined that such Covered Person (i) did not act in good faith in the
reasonable belief that such Covered Person's action was in or not opposed to
the best interests of the Trust; (ii) had acted with willful misfeasance, bad
faith, gross negligence or reckless disregard of the duties involved in the
conduct of such Covered Person's office (iii) for a criminal proceeding, had
reasonable cause to believe that his conduct was unlawful (the conduct
described in (i), (ii) and (iii) being referred to hereafter as "Disabling
Conduct"). A determination that the Covered Person is entitled to
indemnification may be made by (i) a final decision on the merits by a court or
other body before whom the proceeding was brought that the Covered Person to be
indemnified was not liable by reason of Disabling Conduct, (ii) dismissal of a
court action or an administrative proceeding against a Covered Person for
insufficiency of evidence of Disabling Conduct, or (iii) a reasonable
determination, based upon a review of the facts, that the indemnitee was not
liable by reason of Disabling Conduct by (a) a vote of a majority of a quorum
of Trustees who are neither "interested persons" of the Trust as defined in
Section 2(a)(19) of the 1940 Act nor parties to the proceeding (the
"Disinterested Trustees"), or (b) an independent legal counsel in a written
opinion. Expenses, including accountants' and counsel fees so incurred by any
such Covered Person (but excluding amounts paid in satisfaction of judgments,
in compromise or as fines or penalties), may be paid from time to time by one
or more Series to which the conduct in question related in advance of the final
disposition of any such action, suit or proceeding; provided that the Covered
Person shall have undertaken to repay the amounts so paid to such Series if it
is ultimately determined that indemnification of such expenses is not
authorized under this Article 8 and (i) the Covered Person shall have provided
security for such undertaking, (ii) the Trust shall be insured against losses
arising by reason of any lawful advances, or (iii) a majority of a quorum of
the Disinterested Trustees, or an independent legal counsel in a written
opinion, shall have determined, based on a review of readily available facts
(as opposed to a full trial type inquiry), that there is reason to believe that
the Covered Person ultimately will be found entitled to indemnification.

    SECTION 8.5. Compromise Payment. As to any matter disposed of by a
compromise payment by any such Covered Person referred to in Section 8.4
hereof, pursuant to a consent decree or otherwise, no such indemnification
either for said payment or for any other expenses shall be provided unless such
indemnification shall be approved (i) by a majority of a quorum of the
Disinterested Trustees or (ii) by an independent legal counsel in a written
opinion. Approval by the Trustees pursuant to clause (i) or by independent
legal counsel pursuant to clause (ii) shall not prevent the recovery from any
Covered Person of any amount paid to such Covered Person in accordance with
either of such clauses as indemnification if such Covered Person is
subsequently adjudicated by a court of competent jurisdiction not to have acted
in good faith in the reasonable belief that such Covered Person's action was in
or not opposed to the best interests of the Trust or to have been liable to the
Trust or its Shareholders by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of the
Covered Person's office.

    SECTION 8.6. Indemnification Not Exclusive, etc. The right of
indemnification provided by this Article 8 shall not be exclusive of or affect
any other rights to which any such Covered Person or shareholder may be
entitled. As used in this Article 8, a "disinterested" Person is one against
whom none of the actions, suits or other proceedings in question, and no other
action, suit or other proceeding on the same or similar grounds is then or has
been pending or threatened. Nothing contained in this Article 8 shall affect
any rights to indemnification to which personnel of the Trust, other than
Trustees and officers, and other Persons may be entitled by contract or
otherwise under law, nor the power of the Trust to purchase and maintain
liability insurance on behalf of any such Person.

    SECTION 8.7. Liability of Third Persons Dealing with Trustees. No person
dealing with the Trustees shall be bound to make any inquiry concerning the
validity of any transaction made or to be made by the Trustees or to see to the
application of any payments made or property transferred to the Trust or upon
its order.



                                   ARTICLE 9

              DURATION: REORGANIZATION: INCORPORATION; AMENDMENTS

    SECTION 9.1. Duration of Trust. Unless terminated as provided herein, the
Trust shall have perpetual existence.

    SECTION 9.2. Termination of Trust. The Trust may be terminated at any time
by a Majority of the Trustees, subject to the favorable vote of the holders of
not less than a majority of the Shares outstanding and entitled to vote of each
Series of the Trust, or by an instrument or instruments in writing without a
meeting, consented to by the holders of not less than a majority of such
Shares, or by such greater or different vote of Shareholders of any Series as
may be established by the Certificate of Designation by which such Series was
authorized. Upon termination, after paying or otherwise providing for all
charges, taxes, expenses and liabilities, whether due or accrued or anticipated
as may be determined by the Trustees, the Trust shall in accordance with such
procedures as the Trustees consider appropriate reduce the remaining assets to
distributable form in cash, Securities or other property, or any combination
thereof, and distribute the proceeds to the Shareholders, in conformity with
the provisions of Section 6.1(h) hereof. After termination of the Trust or any
Series and distribution to the Shareholders as herein provided, a majority of
the Trustees shall execute and lodge among the records of the Trust an
instrument in writing setting forth the fact of such termination. Upon
termination of the Trust, the Trustees shall thereupon be discharged from all
further liabilities and duties hereunder, and the rights and interests of all
Shareholders shall thereupon cease. Upon termination of any Series, the
Trustees shall thereupon be discharged from all further liabilities and duties
with respect to such Series, and the rights and interests of all Shareholders
of such Series shall thereupon cease.

    SECTION 9.3. Reorganization. The Trustees may sell, convey and transfer all
or substantially all of the assets of the Trust, or the assets belonging to any
one or more Series, to another trust, partnership, association, corporation or
other entity organized under the laws of any state of the United States, or may
transfer such assets to another Series of the Trust, in exchange for cash,
Shares or other Securities (including, in the case of a transfer to another
Series of the Trust, Shares of such other Series), or to the extent permitted
by law then in effect may merge or consolidate the Trust or any Series with any
other Trust or any corporation, partnership, or association organized under the
laws of any state of the United States, all upon such terms and conditions and
for such consideration when and as authorized by vote or written consent of a
Majority of the Trustees and approved by the affirmative vote of the holders of
not less than a majority of the Shares outstanding and entitled to vote of each
Series whose assets are affected by such transaction, or by an instrument or
instruments in writing without a meeting, consented to by the holders of not
less than a majority of such Shares, and/or by such other vote of any Series as
may be established by the Certificate of Designation with respect to such
Series. Following such transfer, the Trustees shall distribute the cash, Shares
or other Securities or other consideration received in such transaction (giving
due effect to the assets belonging to and indebtedness of, and any other
differences among, the various Series of which the assets have so been
transferred) among the Shareholders of the Series of which the assets have been
so transferred; and if all of the assets of the Trust have been so transferred,
the Trust shall be terminated. Nothing in this Section 9.3 shall be construed
as requiring approval of Shareholders for the Trustees to organize or assist in
organizing one or more corporations, trusts, partnerships, associations or
other organizations, and to sell, convey or transfer less than substantially
all of the Trust Property or the assets belonging to any Series to such
organizations or entities.

    SECTION 9.4. Incorporation.  Upon approval by Majority Shareholder Vote,
the Trustees may cause to be organized or assist in organizing a corporation or
corporations under the laws of any jurisdiction or any other trust,
partnership, association or other organization to take over all of the Trust
Property or to carry on any business in which the Trust shall directly or
indirectly have any interest, and to sell, convey and transfer the Trust
Property to any such





                                       25
<PAGE>   32
corporation, trust, association or organization, in exchange for the shares or
securities thereof, or otherwise, and to lend money to, subscribe for the
shares of securities of, and enter into any contracts with any such
corporation, trust, partnership, association or organization in which the Trust
holds or is about to acquire shares or any other interests.  The Trustees may
also cause a merger or consolidation between the Trust or any successor thereto
and any such corporation, trust, partnership, association or other organization
if and to the extent permitted by law, as provided under the law then in
effect. Nothing contained herein shall be construed as requiring approval of
Shareholders for the Trustees to organize or assist in organizing one or more
corporation, trusts, partnerships, associations or other organizations and
selling, conveying or transferring a portion of the Trust Property to such
organizations or entities.

    SECTION 9.5. Amendments; etc. All rights granted to the Shareholders under
this Declaration of Trust are granted subject to the reservation of the right
to amend this Declaration of Trust as herein provided, except that no amendment
shall repeal the limitations on personal liability of any Shareholder or
Trustee or the prohibition of assessment upon the Shareholders (otherwise than
as permitted under Section 6.1(l)) without the express consent of each
Shareholder or Trustee involved. Subject to the foregoing, the provisions of
this Declaration of Trust (whether or not related to the rights of
Shareholders) may be amended at any time, so long as such amendment does not
adversely affect the rights of any Shareholder with respect to which such
amendment is or purports to be applicable and so long as such amendment is not
in contravention of applicable law, including the 1940 Act, by an instrument in
writing signed by a Majority of the Trustees (or by an officer of the Trust
pursuant to the vote of a Majority of the Trustees). Any amendment to this
Declaration of Trust that adversely affects the rights of all Shareholders may
be adopted at any time by an instrument in writing signed by a Majority of the
Trustees (or by an officer of the Trust pursuant to a vote of a Majority of the
Trustees) when authorized to do so by the vote in accordance with Section 7. I
hereof of Shareholders holding a majority of all the Shares outstanding and
entitled to vote, without regard to Series, or if said amendment adversely
affects the rights of the Shareholders of less than all of the Series, by the
vote of the holders of a majority of all the Shares entitled to vote of each
Series so affected.  Notwithstanding any other provisions set forth in this
Declaration of Trust, a provision in this Declaration of Trust requiring
shareholder approval of any action may be amended only with like shareholder
approval.

    SECTION 9.6. Filing of Copies of Declaration and Amendments. The original
or a copy of this Declaration and of each amendment hereto (including each
Certificate of Designation and Certificate of Termination) shall be kept at the
office of the Trust where it may be inspected by any Shareholder.   A restated
Declaration, integrating into a single instrument all of the provisions of this
Declaration which are then in effect and operative, may be executed from time
to time by a Majority of the Trustees and shall, upon execution, be conclusive
evidence of all amendments contained therein and may thereafter be referred to
in lieu of the original Declaration and the various amendments thereto.  A
Certificate of Trust shall be filed in the office of the Secretary of State of
the State of Delaware.

                                   ARTICLE 10

                                 MISCELLANEOUS

to the laws thereof, and the rights of all parties and the construction and

thereto may be simultaneously executed in several counterparts, each of which
so executed shall be deemed to be an original, and such counterparts, together,
shall constitute but one and the same instrument, which shall be sufficiently
evidenced by any such original counterpart.

    SECTION 10.4. Reliance by Third Parties. Any certificate executed by an
individual who, according to the records of the Trust is a Trustee hereunder,
certifying to: (a) the number or identity of Trustees or Shareholders, (b) the
due authorization of the execution of any instrument or writing, (c) the form
of any vote passed at a meeting of Trustees or Shareholders, (d) the fact that
the number of Trustees or Shareholders present at any meeting or executing any

Trustees, (f) the existence or nonexistence of any fact or facts which in any
manner relate to the affairs of the Trust, or (g) the name of the Trust or the
establishment of a Series shall be conclusive evidence as to the matters so
certified in favor of any Person dealing with the Trustees, or any of them, and
the successors of such Person.

    SECTION 10.5. References; Headings. The masculine gender shall include the
feminine and neuter genders. Headings are placed herein for convenience of

or affect the meaning, construction or effect hereof.

    SECTION 10.6. Provisions in Conflict With Law or Regulation.     (a) The
provisions of this Declaration are severable, and if the Trustees shall
determine, with the advice of counsel, that any of such provisions is in
conflict with the 1940 Act, the regulated investment company provisions of the
Internal Revenue Code of 1986 or with other applicable laws and regulations,
the conflicting provision shall be deemed never to have constituted a part of
this Declaration; provided, however, that such determination shall not affect
any of the remaining provisions of this Declaration or render invalid or
improper any action taken or omitted prior to such determination.

    (b) If any provision of this Declaration shall be held invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall
attach only to such provision in such jurisdiction and shall not in any manner
affect such provision in any other jurisdiction or any other provision of this
Declaration in any jurisdiction.

    SECTION 10.7. Use of the Name "American General".  The Trust acknowledges
that it is adopting its name through permission of American General Corporation
(hereinafter referred to as "American General") and agrees that if American
General or a successor to its business (whether such succession be by merger,
consolidation, purchase of assets or otherwise) or a subsidiary thereof should,
at any time and for any cause, cease to be the investment adviser to the Trust,
the Trust shall at the written request of American General and/or any such
successor eliminate the name "American General" from the Trust's corporate name
and from the designations of its shares and will not thereafter use the name
"American General" in any form or combination whatsoever in the conduct of the
Trust's business.  The Trust further acknowledges that American General and its
subsidiaries reserve the right to grant the non-exclusive right to use the name
"American General" to any other corporation, including other investment
companies, whether now in existence or hereafter created.  The foregoing
agreements on the part of the Trust are hereby made binding upon it, its
trustees, officers, shareholders, creditors and all other persons claiming
under or through it.

    IN WITNESS WHEREOF, the undersigned, being the initial Trustee, has set her
hand and seal, for herself and her assigns, unto this Declaration of Trust of
the Trust, as of the day and year first above written.

         AMERICAN GENERAL SERIES PORTFOLIO COMPANY 2 
         Certificate of Designation 
         of
         American General S&P 500 Index Fund

         The undersigned, being the Assistant Secretary of American General
         Series Portfolio Company 2, a Delaware business trust (the "Trust"),
         pursuant to the authority conferred upon the Trustees of the Trust by
         Section 6.1 of the Trust's Agreement and Declaration of Trust
         ("Declaration"), and by the affirmative vote of a Majority of the
         Trustees does hereby establish and designate as a Series of the Trust
         the American General S&P 500 Index Fund (the "Fund") with the following
         rights, preferences and characteristics:

         1. Shares. The beneficial interest in the Fund shall be divided into
         Shares having a nominal or par value of $0.01 per Share, of which an
         unlimited number may be issued, which Shares shall represent interests
         only in the Fund. The Trustees shall have the authority from time to
         time to authorize separate Series of Shares for the Trust as they deem
         necessary or desirable.

         2. Classes of Shares. The Shares of the Fund shall be initially divided
         into five classes --Class A, Class B, Class C, Institutional Class I
         and Institutional Class II. The Trustees shall have the authority from
         time to time to authorize additional Classes of Shares of the Fund.

         3. Sales Charges. Each Class A, Class B, Class C, Institutional Class I
         and Institutional Class II Share shall be subject to such sales
         charges, if any, as may be established from time to time by the
         Trustees in accordance with the Investment Company Act of 1940 (the
         "1940 Act") and applicable rules and regulations of the National
         Association of Securities Dealers, Inc., all as set forth in the Fund's
         prospectus.

         4. Conversion. Each Class B Share of the Fund shall be converted
         automatically, and without any action or choice on the part of the
         Shareholder thereof, into Class A Share of the Fund at such times and
         pursuant to such terms, conditions and restrictions as may be
         established by the Trustees and as set forth in the Fund's Prospectus.

         5. Allocation of Expenses Among Classes. Expenses related solely to a
         particular Class (including, without limitation, distribution expenses
         under an administrative or service agreement, plan or other
         arrangement, however designated) shall be borne by the Class and shall
         be appropriately reflected (in a manner determined by the Trustees) in
         the net asset value, dividends, distribution and liquidation rights of
         the Shares of that Class.



<PAGE>   2



         6. Special Meetings. A special meeting of Shareholders of a Class of
         the Fund may be called with respect to the Rule 12b-1 distribution plan
         applicable to such Class or with respect to any other proper purpose
         affecting only holders of shares of such Class at any time by a
         Majority of the Trustees.

         7. Other Rights Governed by Declaration. All other rights, preferences,
         qualifications, limitations and restrictions with respect to Shares of
         any Series of the Trust or with respect to any Class of Shares set
         forth in the Declaration shall apply to Shares of the Fund unless
         otherwise specified in this Certificate of Designation, in which case
         this Certificate of Designation shall be govern.

         8. Amendments etc. Subject to the provisions and limitations of Section
         9.5 of the Declaration and applicable law, this Certificate of
         Designation may be amended by an instrument signed in writing by a
         Majority of the Trustees (or by an Officer of the Trust pursuant to the
         vote of a Majority of the Trustees) or when authorized to do so by the
         vote in accordance with the Declaration of the holders of a majority of
         all the Shares of the Fund outstanding and entitled to vote or, if such

         necessary or desirable.

         2. Classes of Shares. The Shares of the Fund shall be initially divided

         4. Conversion. Each Class B Share of the Fund shall be converted
         automatically, and without any action or choice on the part of the
         Shareholder thereof, into Class A Share of the Fund at such times and
         pursuant to such terms, conditions and restrictions as may be
         established by the Trustees and as set forth in the Fund's Prospectus.

         5. Allocation of Expenses Among Classes. Expenses related solely to a
         particular Class (including, without limitation, distribution expenses
         under an administrative or service agreement, plan or other
         arrangement, however designated) shall be borne by the Class and shall
         be appropriately reflected (in a manner determined by the Trustees) in
         the net asset value, dividends, distribution and liquidation rights of
         the Shares of that Class.

                                 March 16, 1998


         These are the Bylaws of American General Series Portfolio Company 2, a
trust with transferable shares established under the laws of The State of
Delaware (the "Trust"), pursuant to an Agreement and Declaration of Trust of
the Trust (the "Declaration") made the 16th day of March, 1998, and a
Certificate of Trust filed in the office of the Secretary of State pursuant to
Section 3810 of The Delaware Business Trust Act, Title 12, Chapter 38 of the
Delaware Code.  These Bylaws have been adopted by the Trustees pursuant to the
authority granted by Section 4.14 of the Declaration.

         All words and terms capitalized in these Bylaws, unless otherwise 
defined herein, shall have the same meanings as they have in the
Declaration.

                                   ARTICLE 1

                    SHAREHOLDERS AND SHAREHOLDERS' MEETINGS


         SECTION 1.1.  Meetings.  A meeting of the Shareholders of the Trust
shall be held whenever called by the Chairman, the President or a majority of
the Trustees and whenever election of a Trustee or Trustees by Shareholders is
required by the provisions of the 1940 Act.  Meetings of Shareholders shall
also be called by the Trustees when requested in writing by Shareholders
holding at least ten percent (10%) of the Shares then outstanding for the
purpose of voting upon removal of any Trustee, or if the Trustees shall fail to
call or give notice of any such meeting of Shareholders for a period of thirty
(30) days after such application, then Shareholders holding at least ten
percent (10%) of the Shares then outstanding may call and give notice of such
meeting.   Notice of Shareholders'  meetings shall be given as provided in the
Declaration.

         SECTION 1.2.  Presiding Officer; Secretary.  The President shall
preside at each Shareholders' meeting as Chairman of the meeting, or in the
absence of the President, the Trustees present at the meeting shall elect one
of their number as chairman of the meeting. Unless otherwise provided for by
the Trustees, the Secretary or Assistant Secretary of the Trust shall be the
secretary of all meetings of Shareholders and shall record the minutes thereof.





                                       1
<PAGE>   6
         SECTION 1.3.  Authority of Chairman of Meeting to Interpret
Declaration and Bylaws.  At any Shareholders' meeting the Chairman of the
meeting shall be empowered to determine the construction or interpretation of
the Declaration or these Bylaws, or any part thereof or hereof, and their
ruling shall be final.

         SECTION 1.4.  Voting; Quorum.  At each meeting of Shareholders, except
as otherwise provided by the Declaration, every holder of record of Shares
entitled to vote shall be entitled to a number of votes equal to the number of
Shares standing in his or her name on the Share register of the Trust on the
record date of the meeting.  Shareholders may vote by proxy and the form of any
such proxy may be prescribed from time to time by the Trustees.  A quorum shall
exist if the holders of a majority of the outstanding Shares of the Trust
entitled to vote are present in person or by proxy, but any lesser number shall
be sufficient for adjournments.  At all meetings of the Shareholders, votes
shall be taken by ballot for all matters which may be binding upon the Trustees
pursuant to Section 7.1 of the Declaration.  On other matters, votes of
Shareholders need not be taken by ballot unless otherwise provided for by the
Declaration or by vote of the Trustees, or as required by the 1940 Act, but the
chairman of the meeting may in his or her discretion authorize any matter to be
voted upon by ballot.

         SECTION 1.5.  Inspectors.  At any meeting of Shareholders, the
Chairman of the meeting may appoint one or more Inspectors of Election or
Balloting to supervise the voting at such meeting or any adjournment thereof.
If Inspectors are not so appointed, the chairman of the meeting may, and on the
request of any Shareholder present or represented and entitled to vote shall,
appoint one or more Inspectors for such purpose.  Each Inspector, before
entering upon the discharge of his or her duties, shall take and sign an oath
faithfully to execute the duties of Inspector of Election or Balloting, as the
case may be, at such meeting with strict impartiality and according to the best
of his or her ability.  If appointed, Inspectors shall take charge of the polls
and, when the vote is completed, shall make a certificate of the result of the
vote taken and of such other facts as may be required by law.

         SECTION 1.6.  Records at Shareholder Meetings.  At each meeting of the
Shareholders there shall be open for inspection the minutes of the last
previous Meeting of Shareholders of the Trust and a list of the Shareholders of
the Trust, certified to be true and correct by the Secretary or other proper
agent of the Trust, as of the record date of the meeting or the date of closing
of transfer books, as the case may be.  Such list of Shareholders shall contain
the name of each Shareholder.  Shareholders shall have such other rights and
procedures of inspection of the books and records of the Trust as are granted
to shareholders of a Delaware corporation.

<PAGE>   7
         SECTION 1.7.  Shareholders' Action in Writing.  Nothing in this
Article 1 shall limit the power of the Shareholders to take any action by means
of written instruments without a meeting,  as permitted by Section 7.6 of the
Declaration.

                                   ARTICLE 2

                       TRUSTEES AND TRUSTEES' MEETINGS


         SECTION 2.1.  Number of Trustees.  There shall be initially one (1)
Trustee, and thereafter be such number, authorized by the Declaration, as from
time to time, shall be fixed by a vote adopted by a Majority of the Trustees.

         SECTION 2.2.  Regular Meetings of Trustees.  Regular meetings of the
Trustees may be held without call or notice at such places and at such times as
the Trustees may from time to time determine; provided, that notice of such
determination, and of the time and place of the first regular meeting
thereafter, shall be given to each absent Trustee in accordance with Section
2.4 hereof.

         SECTION 2.3.  Special Meetings of Trustees.  Special meetings of the
Trustees may be held at any time and at any place when called by the President
or the Treasurer or by three (3)  or more Trustees, or if there shall be less
than three (3) Trustees, by any Trustee; provided, that notice of the time and
place thereof is given to each Trustee in accordance with Section 2.4 hereof by
the Secretary or an Assistant Secretary or by the officer or the Trustees
calling the meeting.

         SECTION 2.4.  Notice of Meetings.   Notice of any regular or special
meeting of the Trustees shall be sufficient if given in writing to each
Trustee, and if sent by mail at least five (5) days, by a nationally recognized
overnight delivery service at least two (2) days or by facsimile at least
twenty-four (24) hours, before the meeting, addressed to his or her usual or
last known business or residence address, or if delivered to him or her in
person at least twenty-four (24) hours before the meeting.  Notice of a special
meeting need not be given to any Trustee who was present at an earlier meeting,
not more than thirty-one (31) days prior to the subsequent meeting, at which
the subsequent meeting was called.  Unless statute, these bylaws or a
resolution of the Trustees might otherwise dictate, notice need not state the
business to be transacted at or the purpose of any meeting of the Board of
Trustees.  Notice of a meeting may be waived by any Trustee by written waiver
of notice, executed by him or her before or after the meeting, and such waiver
shall be filed with the records of the meeting. Attendance by a Trustee at a
meeting shall constitute a waiver of notice, except where a Trustee attends a
meeting for the purpose of





                                       3
<PAGE>   8
protesting prior thereto or at its commencement the lack of notice.  No notice
need be given of action proposed to be taken by unanimous written consent.

         SECTION 2.5.  Quorum: Presiding Trustee.  At any meeting of the
Trustees, a Majority of the Trustees shall constitute a quorum. Any meeting may
be adjourned from time to time by a majority of the votes cast upon the
question, whether or not a quorum is present, and the meeting may be held as
adjourned without further notice. Unless the Trustees shall otherwise elect,
generally or in a particular case, the Chairman shall be the presiding Trustee
at each meeting of the Trustees or in the absence of the Chairman, the
President shall preside over the meeting.  In the absence of both the Chairman
and the President, the Trustees present at the meeting shall elect one of their
number as presiding Trustee of the meeting.

         SECTION 2.6.  Participation by Telephone.  One or more of the Trustees
may participate in a meeting thereof or of any Committee of the Trustees by
means of a conference telephone or similar communications equipment allowing
all persons participating in the meeting to hear each other at the same time.
Participation by such means shall constitute presence in person at a meeting.

         SECTION 2.7.  Location of Meetings.  Trustees' meetings may be held at
any place, within or without the State of Delaware.

         SECTION 2.8.  Actions by Trustees.   Unless statute, the charter or
Bylaws requires a greater proportion, action of a majority of the Trustees
present at a meeting at which a quorum is present is action of the Board of
Trustees.  The results of all voting shall be recorded by the Secretary in the
minute book.

         SECTION 2.9.  Rulings of Presiding Trustee.  All other rules of
conduct adopted and used at any Trustees' meeting shall be determined by the
presiding Trustee of such meeting, whose ruling on all procedural matters
shall be final.

         SECTION 2.10. Trustees' Action in Writing.  Nothing in this Article 2
shall limit the power of the Trustees to take action by means of a written
instrument without a meeting, as provided in Section 4.2 of the Declaration.

written instrument signed by him or her and delivered to the Chairman, the
President or the Secretary or to a meeting of the Trustees. Such resignation
shall be effective upon receipt unless specified to be effective at some other
time.

                                     SHARES

         SECTION 6.1.  Issuance of Shares.  The Trustees may issue an unlimited
number of Classes of Shares of any or all Series either in certificated or
uncertificated form.  They may issue certificates to the holders of a Class of
Shares of a Series which was originally issued in uncertificated form, and if
they have issued Shares of any Series in certificated form, they may at any
time discontinue the issuance of Share certificates for such Series and may, by
written notice to such Shareholders of such Series require the surrender of
their Share certificates to the Trust for cancellation, which surrender and
cancellation shall not affect the ownership of Shares for such Series.

         SECTION 6.2.  Uncertificated Shares.  For any Class of Shares for
which the Trustees issue Shares without certificates, the Trust or the Transfer
Agent may either issue receipts therefor or may keep accounts upon the books of
the Trust for the record holders of such Shares, who shall in either case be
deemed, for all purposes hereunder, to be the holders of such Shares as if they
had received certificates therefor and shall be held to have expressly assented
and agreed to the terms hereof and of the Declaration.

         SECTION 6.3.  Share Certificates.  For any Class of Shares for which
the Trustees shall issue Share certificates, each Shareholder of such Class
shall be entitled to a certificate stating the number of Shares owned by him or
her in such form as shall be prescribed from time to time by the Trustees. Such
certificate shall be signed by the President or a Vice President, and by the
Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary
of the Trust.  Such signatures may be facsimiles if the certificate is
countersigned by a Transfer Agent, or by a Registrar, other than a Trustee,
officer or employee of the Trust. In case any officer who has signed or whose
facsimile signature has been placed on such certificate shall cease to be such
officer before such certificate is issued, it may be issued by the Trust with
the same effect as if he were such officer at the time of its issue.

         SECTION  6.4. Lost, Stolen, etc., Certificates.    If  any certificate
for certificated Shares shall be lost, stolen, destroyed or mutilated, the
Trustees may authorize the issuance of a new certificate of the same tenor and
for the same number of Shares in lieu thereof.  The Trustees shall require the
surrender of any mutilated certificate in respect of which a new certificate is
issued, and may, in their discretion, before the issuance of a new certificate,
require the owner of a lost, stolen or destroyed certificate, or the owner's
legal representative, to make an affidavit or affirmation setting forth such
facts as to the loss, theft or destruction as they deem





                                       9

necessary, and to give the Trust a bond in such reasonable sum as the Trustees
direct, in order to indemnify the Trust.

                               TRANSFER OF SHARES

         SECTION 7.1.  Transfer Agents, Registrars, etc.  As approved in
Section 5.2(e) of the Declaration, the Trustees shall have the authority to
employ and compensate such transfer agents and registrars with respect to the
Shares of the Trust as the Trustees shall deem necessary or desirable.  In
addition, the Trustees shall have the power to employ and compensate such
dividend dispersing agents, warrant agents and agents for reinvestment of
dividends as they shall deem necessary or desirable.  Any of such agents shall
have such power and authority as is delegated to any of them by the Trustees.

         SECTION 7.2   Transfer of Shares.  The Shares of the Trust shall be
transferable on the books of the Trust only upon delivery to the Trustees or a
transfer agent of the Trust of proper documentation as provided in Section
6.1(m) of the Declaration.  The Trust, or its transfer agents, shall be
authorized to refuse any transfer unless and until presentation of such
evidence as may be reasonably required to show that the requested transfer is
proper.

         SECTION 7.3   Registered  Shareholders.  The Trust may deem and treat
the holder of record of any Shares the absolute owner thereof for all purposes
and shall not be required to take any notice of any right or claim of right of
any other person.

                                   AMENDMENTS

         SECTION 8.1.  Bylaws Subject to Amendment.  These Bylaws may be
altered, amended or repealed, in whole or in part, at any time by vote of the
holders of a majority of the Shares issued, outstanding and entitled to vote.
The Trustees, by vote of a Majority of the Trustees (unless a greater vote is
required by Section 2.8 hereof), may alter, amend or repeal these Bylaws,  in
whole or in part, including Bylaws adopted by the Shareholders, except with
respect to any provision hereof which by law, the Declaration or these Bylaws

waiver of notice, as the case may be, of the meeting of the Trustees or
Shareholders at which such action is taken, or (ii) all of the Trustees or
Shareholders, as the case may be, are present at such meeting and all agree to

                         INVESTMENT ADVISORY AGREEMENT


This AGREEMENT made this _____ day of __________, 1998, by and between THE
VARIABLE ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as the
"ADVISER," and AMERICAN GENERAL SERIES PORTFOLIO COMPANY 2, hereinafter
referred to as the "FUND."

         The ADVISER and the FUND recognize the following:

                 (a)  The ADVISER is a life insurance company organized under
         Chapter 3 of the Texas Insurance Code and an investment adviser

                 (b)  The FUND is an investment company organized under the
         laws of Delaware as a business trust, as a series type of investment
         company issuing separate classes (or series) of shares of beneficial
         interest  and is registered as an open-end, management investment
         company under the Investment Company Act of 1940 (the "1940 Act").
         The 1940 Act prohibits any person from acting as an investment adviser
         of a registered investment company except pursuant to a written
         contract.

                 (c)  The FUND currently consists of eighteen portfolios

         Bond Fund, American General Balanced Fund, American General Large Cap
         Growth Fund, American General Small Cap Growth Fund, American General
         Mid Cap Value Fund, American General Large Cap Value Fund, American
         General International Growth Fund, American General Money Market Fund,
         American General Socially Responsible Fund, American General Growth
         Lifestyle Fund, American General Moderate Growth Lifestyle Fund, and
         American General Conservative Growth Lifestyle Fund.  In accordance
         with the FUND's Agreement and Declaration of Trust (the "Declaration")
         and Bylaws, new Funds may be added to the FUND upon approval of the
         FUND's Board of Trustees without approval of the FUND's shareholders.
         This Agreement will apply only to the Fund(s) and any other Fund as
         may be added or deleted by amendment to the attached Schedule A
         ("Covered Funds").

                 (d)  The FUND currently sells its shares to separate accounts
         established by the ADVISER and its affiliates to fund certain variable
         annuity contracts and to employee thrift plans maintained by the
         ADVISER and/or its affiliates.

         The ADVISER and the FUND AGREE AS FOLLOWS:


1.       SERVICES RENDERED AND EXPENSES PAID BY ADVISER

         The ADVISER, subject to the control, direction, and supervision of the
FUND's Board of Trustees and in conformity with applicable laws, the FUND's
Declaration, Bylaws, registration statements, prospectus and stated investment
objectives, policies and restrictions shall:

                 (a)  manage the investment and reinvestment of the assets of
         the Covered Funds including, for example, the evaluation of pertinent
         economic, statistical, financial, and other data, the determination of
         the industries and companies to be represented in each Covered Fund's
         portfolio, and the formulation and implementation of investment
         programs.

                 (b)  maintain a trading desk and place all orders for the
         purchase and sale of portfolio investments for each Covered Fund's
         account with brokers or dealers selected by the ADVISER, or arrange
         for any other entity to provide a trading desk and to place orders
         with brokers and dealers selected by the ADVISER, subject to the
         ADVISER's control, direction, and supervision.
<PAGE>   2
                 (c)  conduct and manage the day to day operations of each
         Covered Fund including, for example, the preparation  of registration
         statements, prospectuses, reports, proxy solicitation materials and
         amendments thereto, and the furnishing of legal services (except those
         services provided by outside counsel to the FUND selected by the Board
         of Trustees).

                 (d)  furnish to the Covered Funds office space, facilities,
         equipment and personnel adequate to provide the services described
         above and pay the compensation to the FUND's trustees and officers who
         are interested persons of the ADVISER.

         In performing the services described in paragraph (b) above, the
ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution.  The ADVISER shall also use its best
efforts to obtain for the Covered Funds any tender and exchange offer
solicitation fees, other fees, and similar payments available in connection
with the portfolio transactions of the Covered Funds.  Subject to prior
authorization by the FUND's Board of Trustees of appropriate policies and
procedures, the ADVISER may cause the Covered Funds to pay to a broker a
commission, for effecting a portfolio transaction, in excess of the commission
another broker would have charged for effecting the same transaction, if the
first broker provided brokerage and\or research services, including statistical
data, to the ADVISER.  The ADVISER shall not be deemed to have acted
unlawfully, or to have breached any duty created by this Agreement, or
otherwise, solely by reason of acting according to such authorization.

         The ADVISER shall maintain records adequately demonstrating compliance
with its obligations under this Agreement and report periodically to the FUND's
Board of Trustees regarding the performance of services under this Agreement.

         Except as otherwise agreed, or as otherwise provided herein, the
ADVISER shall bear the expense of discharging its responsibilities hereunder
and the FUND shall pay, or arrange for others to pay, all its expenses other
than those which part 2 of this Agreement expressly states are payable to the
ADVISER.  Expenses payable by the FUND include, but are not limited to, (i)
interest and taxes; (ii) broker's commissions and other expenses of purchasing
and selling portfolio investments; (iii) compensation of trustees and officers
other than those persons who are interested persons of the ADVISER; (iv) fees
of outside counsel to and of independent auditors of the FUND selected by the
Board of Trustees; (v) fees for accounting services; (vi) custodial,
registration, and transfer agency fees; (vii) expenses related to the
repurchase or redemption of its shares including expenses related to a program
of periodic repurchases or redemptions; (viii) expenses of issuing its shares
against payment therefor by, or on behalf of, the subscribers thereto; (ix)
fees and related expenses of registering and qualifying the FUND and its shares
for distribution under state and federal securities laws; (x) expenses of
printing and mailing to existing shareholders of registration statements,
prospectuses, reports, notices and proxy solicitation materials of the FUND;
(xi) all other expenses incidental to holding meetings of the FUND's
shareholders including proxy solicitations therefor; (xii) expenses for
servicing shareholder accounts; (xiii) insurance premiums for fidelity coverage
and errors and omissions insurance; (xiv) dues for the FUND's membership in
trade associations approved by the Board of Trustees; (xv) such non-recurring
expenses as may arise, including those associated with actions, suits, or
proceedings to which the FUND is a party and the legal obligation which the
FUND may have to indemnify its officers, trustees and employees with respect
thereto.  The FUND shall allocate the foregoing expenses among the Covered
Funds and, to the extent that any of the foregoing expenses are allocated
between the Covered Funds and any other Funds or entities, such allocations
shall be made pursuant to methods approved by the Board of Trustees.

2.       COMPENSATION OF ADVISER

         The FUND shall pay to the ADVISER, as compensation for the services
rendered, facilities furnished and expenses paid by the ADVISER, a monthly fee
based on each Covered Fund's average monthly net asset value computed for each
Covered Fund as provided for in the fee schedule attached hereto as Schedule A.
Schedule A may be amended from time to time, provided that amendments are made
in conformity with applicable laws and regulations and the Declaration and
Bylaws of the FUND.  Any change in Schedule A pertaining to any existing or new
Fund shall not be deemed to affect the interest of any other Fund and shall not
require the approval of shareholders of any other Fund.





                                       2
<PAGE>   3
         The average monthly net asset value shall be determined by taking the
mean average of all of the determinations of net asset value, made in the
manner provided in the FUND's Declaration, for each business day during a given
calendar month.  The FUND shall pay this fee for each calendar month as soon as
practicable after the end of that month.

         The ADVISER shall promptly reduce its monthly fee by the amount of any
commissions, tender and exchange offer solicitation fees, other fees, or
similar payments received by the ADVISER, or any affiliated person of the
ADVISER, in connection with any Covered Fund's portfolio transactions, less the
amount of any direct expenses incurred by the ADVISER, or any affiliated person
of the ADVISER, in obtaining such commissions, fees, or payments.

         If the ADVISER serves for less than a whole month, the foregoing
compensation shall be prorated.

3.       SCOPE OF ADVISER'S DUTIES

         The ADVISER, and any person controlling, controlled by or under common
control with the ADVISER, shall remain free to provide similar investment
advisory services to other persons or engage in any other business or activity
which does not impair the services which the ADVISER renders to the Covered
Funds.

         Except as otherwise required by the Investment Company Act of 1940,
any of the shareholders, trustees, officers and employees of the FUND may be a
shareholder, director, officer or employee of, or be otherwise interested in,
the ADVISER, and in any person controlling, controlled by or under common
control with the ADVISER; and the ADVISER, and any person controlling,
controlled by or under common control with the ADVISER, may have an interest in
the FUND.

         The ADVISER shall not be liable to the FUND, or to any shareholder in
the FUND, for any act or omission in rendering services under this 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 the
ADVISER.

         The ADVISER may from time to time employ or associate with itself any
person or persons believed to be particularly fitted to assist in its
performance of services under this Agreement, provided that any such person who
serves or acts as an investment adviser separate from the ADVISER will do so
pursuant to a sub-advisory agreement as provided in the following paragraph.
The compensation of any such persons will be paid by the ADVISER, and no
obligation will be incurred by, or on behalf of, the FUND with respect to them.

         Notwithstanding any other provision of this Agreement, the FUND hereby
authorizes the ADVISER to employ an investment sub-adviser for any one or more
of the Covered Funds for the purpose of providing investment management
services with respect to such Covered Funds, provided that (a) the compensation
to be paid to such investment sub- adviser shall be the sole responsibility of
the ADVISER, (b) the duties and responsibilities of the investment sub- adviser
shall be as set forth in a sub-advisory agreement including the ADVISER and the
investment sub-adviser as parties, (c) such sub-advisory agreement shall be

         This Agreement shall become effective as to the Covered Funds set

Unless sooner terminated as provided herein, this Agreement shall continue in

date.  Thereafter this Agreement shall continue in effect, but with respect to
any Covered Fund, subject to the termination provisions and all other terms and
conditions hereof, only so long as such continuance is approved at least
annually by the vote of a majority of the FUND's trustees who are not parties
to this Agreement 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 FUND's Board of Trustees or a majority of that Fund's
outstanding voting securities.

         This Agreement shall automatically terminate in the event of its
assignment.  The Agreement may be terminated as to any Covered Fund at any time
by the FUND's Board of Trustees, by vote of a majority of that Fund's
outstanding voting securities, or by the ADVISER, on not more than 60 days' nor
less than 30 days' written notice, or upon such shorter notice as may be
mutually agreed upon.  Such termination shall be without the payment of any
penalty.

5.       APPLICABILITY OF FEDERAL SECURITIES LAWS

         This Agreement shall be interpreted in accordance with applicable
federal securities laws and regulations, including definitions therein and such
exemptions as may be granted to the ADVISER or the FUND by the Securities and
Exchange Commission or such interpretive positions as may be taken by the
Commission or its staff.  To the extent that the applicable law of the State of
Texas, or any of the provisions herein, conflict with applicable provisions of
the federal securities laws, the latter shall control.

6.       MISCELLANEOUS PROVISIONS

         For the purposes of this Agreement, the terms "affiliated person,"
"assignment," "interested person," and "majority of outstanding voting
securities" shall have their respective meanings defined in the 1940 Act and
the Rules and Regulations thereunder, subject, however, to such exemptions as
may be granted to either the ADVISER or the FUND by the Securities and Exchange
Commission (the "Commission"), or such interpretive positions as may be taken
by the Commission or its staff, under the 1940 Act, and the term "brokerage and
research services" shall have the meaning given in the Securities Exchange Act
of 1934 and the Rules and Regulations thereunder.

         The execution of this Agreement has been authorized by the FUND's
Trustees and by the sole shareholder.  This Agreement is executed on behalf of
the FUND or the Trustees of the FUND as Trustees and not individually and that
the obligations of this Agreement are not binding upon any of the Trustees,
officers or shareholders of the FUND individually, but are not binding only
upon the assets and property of the FUND.  A Certificate of Trust in respect of
the FUND is on file with the Secretary of State of Delaware.

         All questions concerning the validity, meaning and effect of this
Agreement shall be determined in accordance with the laws (without giving
effect to the conflict-of-law principles thereof) of the State of Delaware
applicable to contracts made and to be performed in that state.
