Unless otherwise specified in this prospectus, the words we, our, and VALIC mean
The Variable Annuity Life Insurance Company and any Investment Sub-adviser that
we work with. The words you and your mean the participant.
 
American General Series Portfolio Company 3 (the "Series Company") was organized
as a Delaware business trust on May 6, 1998.
 
   
The Series Company is an open-end management investment company and currently
consists of 18 different Funds, each of which is described in detail in this
prospectus. We serve as each Fund's Investment Adviser and, in this role, report
directly to the Series Company's Board of Trustees. As Investment Adviser, we
oversee the Funds' day to day operations, supervise the purchase and sale of
Fund investments and perform the cash management function. Investment
Sub-advisers make the investment decisions for the Funds that they manage, as
described more fully in this prospectus. However, we make investment decisions
for, and are directly responsible for the day to day management of, the Socially
Responsible Fund, the Money Market Fund and the Lifestyle Funds. For more
information, see "About the Funds' Management" in this prospectus.
    
 
Individuals can't invest in the shares of these Funds directly. Instead, they
participate through an annuity or variable life contracts or employer plan with
VALIC or one of its affiliates, or employee thrift plans maintained by VALIC or
American General Corporation. Most often employers set up these contracts so
they can offer their employees a way to save for retirement. Retirement plans
through employers may be entitled to tax benefits that individual retirement
plans may not be entitled to. These tax benefits are fully explained in your
contract prospectus.
 
After you invest in a Fund, you participate in Fund earnings or losses, in
proportion to the amount of money you invest. Depending on your contract, if you
withdraw your money before retirement, you may incur charges and additional tax
liabilities. However, to save for retirement, you generally should let your
investments and their earnings build. At retirement, you may withdraw all or a
portion of your money, leave it in the account until you need it, or start
receiving annuity payments. At a certain age you may be required to begin
withdrawals.
 
All inquiries regarding this prospectus should be directed, in writing, to VALIC
Customer Service, A3-01, 2929 Allen Parkway, Houston, Texas 77019, or by calling
1-800-633-8960.
 
   
All inquiries regarding contracts issued by American General Life Insurance
Company (AGL) should be directed to AGL's Annuity Administration Department,
2727-A Allen Parkway, Houston, Texas 77019-2191 or call 1-800-813-5065. AGL is a
member of the American General Corporation group of companies, as is VALIC.
    
 
Open-end means shares
of the Funds can be

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

ABOUT THE SERIES COMPANY'S MANAGEMENT
    
- --------------------------------------------------------------------------------
 
   
INVESTMENT ADVISER
    
 
   
VALIC, a stock life insurance company, has been in the investment advisory
business since 1960. VALIC, as of June 30, 1998, had over $8.5 billion in assets
under management. 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. The
American General Corporation group of companies is a leading provider of
retirement services, life insurance and consumer loans. Members of the American
General Corporation group of companies operate in each of the 50 states and
Canada.
    
 
   
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. For the International Growth Fund, the Large Cap Growth
Fund, the Mid Cap Growth Fund, the Small Cap Growth Fund, the International
Value Fund, the Large Cap Value Fund, the Mid Cap Value Fund, the Small Cap
Value Fund, the Balanced Fund, the High Yield Bond Fund, the Strategic Bond
Fund, the Domestic Bond Fund, and the Core Bond Fund, VALIC employs Investment
Sub-advisers who make investment decisions for such Fund(s). 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 the Series Company. The Investment
Advisory Agreement provides for the Series Company to pay all expenses not
specifically assumed by VALIC. 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 and expenses of
servicing shareholder accounts (e.g., daily calculation of the net asset value).
The Series Company allocates these expenses to each Fund in a manner approved by
the Board of Trustees. After the second year, this agreement will be renewed
once each year, by the Series Company Board of Trustees.
    
 
   
One Investment Advisory Agreement dated August 26, 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 Series Company's 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-advisers 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.

THE SUB-ADVISERS
 
   
The Funds do not pay the Sub-advisers directly. According to the agreements,
VALIC pays them periodically a fee based upon the Funds' average daily net asset
values. We pay them a percentage of what is paid to us by the Funds. We and the
Sub-advisers may agree to change the amount of money we pay them. Any such
change increasing the charge paid by a 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 September [9], 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 the 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 initial shareholder of each Fund, by unanimous written
consent dated August 26, 1998, voted 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.
    
 
   
Under the Investment Sub-advisory Agreement we have with AGIM, we pay AGIM a
monthly fee based on the average daily net asset values of the Core Bond Fund at

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
a quarterly fee 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 in excess
of $12 million.

Under the Investment Sub-Advisory Agreement we have with Jacobs Asset
Management, we pay Jacobs Asset Management a monthly fee based on the average
daily net asset values of the International Growth Fund at an annual rate of
0.65% of the first $100 million and 0.55% on assets over $100 million.
 
Under the Investment Sub-Advisory Agreement we have with N&B Management, we pay
N&B Management a monthly fee based on the average daily net asset values of the
Mid Cap Value Fund at the annual rate of 0.50% of the first $100 million, 0.475%
of the next $150 million, 0.45% of the next $250 million, 0.425% of the next
$250 million and 0.40% on assets over $750 million.
 
   
Under the Investment Sub-Advisory Agreement we have with State Street Global
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 written contracts, 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:
 
   
  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
   
(Combination of Growth and Income Categories)
    
 
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 Company 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:
 
   
  High Yield Bond Fund
    
   
  Strategic Bond Fund
    
  Domestic Bond Fund
   
  Core 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
 
   
The proliferation of mutual funds over the last several years has left many
investors in search of a simple means to manage their long-term investments.
With new investment categories emerging each year and with each mutual fund
reacting differently to political, economic and business events, many investors
are forced to make complex investment decisions in the face of limited
experience, time and personal resources. The Lifestyle Funds are designed to
meet the needs of investors who prefer to have their asset allocation decisions
made by professional money managers, are looking for an appropriate core
investment for their retirement portfolio and appreciate the advantages of broad
diversification.
    
 
   
A Lifestyle Fund does not invest directly in portfolio securities but, rather,
invests in a combination of Series Company 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
 
                                        9
<PAGE>   14
- --------------------------------------------------------------------------------
 
   
sell and buy investments as part of their investment strategy. In other Funds,
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 annual portfolio turnover rates for each of the Funds except the
Money Market Fund are as follows:

Conservative Growth Lifestyle      10-20%

A portfolio turnover rate of 100% or more a year is considered high. A high rate
increases a Fund's transaction costs and expenses.
    
 
ABOUT FUND PERFORMANCE
 
From time to time the Series Company may advertise Fund performance information
such as Fund average total return and index total return. Information as to how
this Fund performance information is calculated appears in the Statement of
Additional Information. Additionally, information on separate account
performance appears in your contract prospectus.

Jacobs Asset Management
 
PORTFOLIO MANAGER
 
   
This Fund is managed by an investment committee comprised of the following
individuals: Daniel L. Jacobs, Wai W. Chin, Robert J. Jurgens and Cynthia A.
New. 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 from
1989 to April 1995. 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. Ms. New has been Director, Latin American
Research, of the Sub-adviser since July 1998. Prior to this, Ms. New was an
equity analyst at Pioneer Management Corporation from December 1997 to June 1998
and was at Templeton International Council from June 1993 to December 1997,
where she had research and portfolio management responsibilities for developed
and emerging market corporate and government debt securities.
    
 
INVESTMENT OBJECTIVE
 
   
Seeks to provide long-term capital appreciation by investing in equity
securities of non-U.S. companies, the majority of which are expected to be in
developed 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, including foreign political and economic developments, fluctuations in
foreign exchange rates and limited publicly available information. 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 diversify its investments
among 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
equity securities including those of smaller capitalization companies.

       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

       we think economic, political or market conditions make it too risky for
 
       us to follow our general guidelines.

INTERNATIONAL GROWTH FUND
   
- --------------------------------------------------------------------------------
    
 
1. The Templeton Performance Information
 
   
The International Growth Fund recently commenced operations and, therefore, has
no investment performance record. The performance information shown herein 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, net
of the Templeton International Fund's fees and expenses. The inception date for
the Templeton International Fund was May 1, 1992. During Mr. Jacobs tenure as
the portfolio manager of the Templeton International Fund, from May 1, 1992 to
June 30, 1995, he was primarily responsible for the day-to-day management and no
other person had a significant role in achieving the Templeton International
Fund's performance.
    
 
   
The International Growth Fund is subject to investment limitations,
diversification requirements and other restrictions imposed on registered mutual
funds by the 1940 Act and Subchapter M of the Internal Revenue Code.
    
 
   
Total fees (after expense reimbursements) for the International Growth Fund are
higher than the total fees incurred by the Templeton International Fund.
Consequently, the performance results for the Templeton International Fund would
have been lower if the Templeton International Fund had the same expenses as the
International Growth Fund. The performance of the Templeton International Fund
has been calculated in accordance with SEC performance standards. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of SEC performance standards. THE PERFORMANCE INFORMATION
HEREIN IS BASED ON THE TEMPLETON INTERNATIONAL FUND WHICH WAS MANAGED IN
SUBSTANTIALLY THE SAME MANNER AND BY THE SAME INDIVIDUAL WHO MANAGED THE
INTERNATIONAL GROWTH FUND AND DOES NOT REFLECT THE PERFORMANCE OF THE
INTERNATIONAL GROWTH 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,
though not necessarily identical, to those employed by the Sub-adviser with
respect to separately managed accounts of the Sub-adviser ("Separately Managed
Accounts"). The chart herein shows the historical investment performance for a
composite of the Sub-adviser's Separately Managed Accounts ("Sub-adviser
Composite") which were managed by the Sub-adviser in substantially the same
manner and by the same individuals who manage the International Growth Fund. The
Sub-adviser Composite represents the total return, net of all fees and expenses,
of all 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 Subchapter M of the
Internal Revenue Code. If the Separately Managed Accounts included in the
Sub-adviser Composite had been subject to the requirements imposed on registered
mutual funds, their performance might have been lower.
    
 
   
Total fees (after expense reimbursements) for the International Growth Fund are
higher than the total fees incurred by the Separately Managed Accounts
comprising the Sub-adviser Composite. Consequently, the performance results for
the Sub-adviser Composite would have been lower if the Sub-adviser's Separately
Managed Accounts had the same expenses as the International Growth Fund. The
performance of the Sub-adviser Composite has been calculated in accordance with
SEC performance standards. See "Performance and Yield Information" in the
Statement of Additional Information for a description of SEC performance
standards. THE PERFORMANCE INFORMATION HEREIN IS BASED ON A COMPOSITE OF THE
SUB-ADVISER'S SEPARATELY MANAGED ACCOUNTS WHICH ARE MANAGED IN SUBSTANTIALLY THE
SAME MANNER AND BY THE SAME INDIVIDUALS WHO MANAGE THE INTERNATIONAL GROWTH FUND
AND DOES NOT REFLECT THE PERFORMANCE OF THE INTERNATIONAL GROWTH FUND ITSELF.

INVESTMENT SUB-ADVISER
 
Goldman Sachs Asset Management
 
PORTFOLIO MANAGER
 
   
The Fund is managed by the following individuals: Robert C. Jones; Kent A.
Clark; Victor H. Pinter; and Melissa Brown. Mr. Jones, Managing Director, joined
the Sub-adviser in 1989. From 1987 to 1989, he was the senior quantitative
analyst in the Goldman Sachs Investment Research Department and the author of
the monthly Stock Selection publication. Mr. Clark, Vice President, joined the
Sub-adviser's quantitative equity management team in 1992. Prior to joining the
Sub-adviser, Mr. Clark studied for a Ph.D in finance at the University of
Chicago. Mr. Pinter, Vice President, joined the Sub-adviser in 1990. From 1985
to 1990, he was a project manager in the Sub-adviser's Information Technology
Division. Ms. Brown, Vice President, joined the Sub-adviser in 1998. From 1994
to 1998, Ms. Brown was the director of Quantitative Equity Research and served
on the Investment Policy Committee at Prudential Securities.
    
 
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 objective.
    
INVESTMENT RISK
   
This Fund invests almost entirely in equity securities. The value of equity
securities 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 invests primarily in the equity securities of large cap U.S. issuers.
Large cap U.S. issuers are companies that meet the market capitalization range
of companies comprising the Russell 1000 Growth Index.
    
 
   
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 and foreign securities 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
    
- --------------------------------------------------------------------------------
 
   
The Large Cap Growth Fund recently commenced operations and, therefore, has no
investment performance record. However, the Large Cap Growth Fund's investment
objective, policies and strategies are substantially similar to those employed
by the Sub-adviser with respect to sixteen accounts ("Combined Accounts"),
including fourteen advisory accounts ("Accounts") and two registered mutual
funds ("Funds"). The chart herein shows the historical investment performance
for a composite of the Combined Accounts ("Combined Accounts Composite"), which
were managed by the Sub-adviser in substantially the same manner and by the same
individuals who manage the Large Cap Growth Fund. The Combined Accounts
Composite includes all Combined Accounts net of average fees and expenses
charged by the Accounts and the Funds. These expenses include investment
advisory fees but do not include custodial fees (other than for the mutual
funds), which, if included, could lessen the performance presented. The
inception dates of the Combined Accounts comprising the Combined Accounts
Composite range from November 11, 1991 to January 30, 1998.
    
 
   
The Accounts included 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 Subchapter M of 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.
    
 
   
Total fees (after expense reimbursements) for the Large Cap Growth Fund are
higher than the total fees historically incurred by the Combined Accounts
comprising the Combined Accounts Composite. Consequently, the performance
results for the Combined Accounts Composite would have been lower if the
Combined Accounts Composite had the same expenses as the Large Cap Growth Fund.
    
 
   
The performance of the Combined Accounts Composite has been calculated in
accordance with performance presentation standards of the Association for
Investment Management and Research ("AIMR"). The AIMR method of calculating
performance is different from SEC performance standards, which are described
under "Performance and Yield Information" in the Statement of Additional
Information. THE PERFORMANCE INFORMATION HEREIN IS BASED ON A COMPOSITE OF THE

Alexander III, Noreen A. Frost, and Stephon A. Jackson assist Mr. Brown in the
management of the Fund. Mr. Hall, Senior Vice President and Portfolio
Manager/Analyst, joined the Sub-adviser in September 1993. Mr. Alexander, Vice
President and Portfolio Manager/Analyst, joined the Sub-adviser in October 1995.
Prior to this, Mr. Alexander was a Securities Analyst at Legg Mason Wood Walker
from June 1994 to October 1995. From June 1990 to January 1994, Mr. Alexander
was a Securities Analyst at Alex Brown & Sons, Inc. Ms. Frost, Vice President

INVESTMENT OBJECTIVE
 
   
Seeks capital appreciation principally through investments in medium
capitalization equity securities, such as common and preferred stocks and
securities convertible into common stocks. Current income is a secondary
objective.
    
 
INVESTMENT RISK
 
   
This Fund invests mostly in equity securities of medium sized companies that we
believe are undervalued in the marketplace. The value of any equity security may
rise or fall over long or short periods of time. Although these equity
securities 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. Medium capitalization companies include companies with
a market capitalization of $1 to $7 billion. We will seek to achieve capital
appreciation through an opportunistic 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 investments, 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.

MID CAP GROWTH FUND
    
- --------------------------------------------------------------------------------
 
   
The Mid Cap Growth Fund recently commenced operations and, therefore, 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 discretionary investment management accounts
under their management ("Combined Accounts"). The chart herein shows the
investment performance for a composite of these Combined Accounts ("Combined
Accounts Composite") which were managed by the Sub-adviser in substantially the
same manner and by the same individuals who manage the Mid Cap Growth Fund. The
Combined Accounts Composite includes all Combined Accounts, net of account fees
and expenses. The inception dates of the Combined Accounts comprising the
Combined Accounts Composite range from January 1, 1993 to March 31, 1998.
    
 
   
The Combined 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 Subchapter M of the
Internal Revenue Code. If the Combined Accounts included in the Combined
Accounts Composite had been subject to the requirements imposed on mutual funds,
their performance might have been lower.
    
 
   
Total fees (after expense reimbursements) for the Mid Cap Growth Fund are lower
than the total fees historically incurred by the Combined Accounts comprising
the Combined Accounts Composite. Consequently, the performance results for the
Combined Accounts Composite would have been lower if the Combined Accounts
Composite had the same expenses as the Mid Cap Growth Fund. The performance of
the Combined Accounts Composite has been calculated in accordance with SEC
performance standards. See "Performance and Yield Information" in the Statement
of Additional Information for a description of SEC performance standards. THE
PERFORMANCE INFORMATION HEREIN IS BASED ON A COMPOSITE OF THE SUB-ADVISER'S
COMBINED ACCOUNTS WHICH ARE MANAGED IN SUBSTANTIALLY THE SAME MANNER AND BY THE

PORTFOLIO MANAGER
 
   
Candice Eggerss, Stephen J. Rich 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. Mr. Rich is a portfolio manager in the Small Cap
Equity Group. He manages a portion of the J.P. Morgan U.S. Small Company Fund
and other small cap portfolios. In addition to his present position, his 7 years
of experience in equity portfolio management include positions in J.P. Morgan
Investment Management Inc.'s Structured Equity and Balanced/Equity groups.
Before joining J.P. Morgan Investment Management Inc. in 1991, Mr. Rich received
an AB from Princeton University. Mr. Rich currently is pursuing a Master's in
Business Administration at New York University. 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 equity securities of small
capitalization growth companies.
    
 
INVESTMENT RISK
 
   
Small capitalization companies may not have the financial strength to do well in
difficult times. Because they are small, the prices of their equity securities
may fluctuate more over the short term but they have more potential to grow.
This means their value may offer greater potential for appreciation. The equity
securities that the Fund invests in involve certain risks such as market risks.
For a discussion of these risks, see "A Word About Risk" in this prospectus.
    
 
INVESTMENT STRATEGY
 
   
This Fund invests in small capitalization U.S. companies, which are 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 equity securities that the Sub-adviser's research and valuation process
indicate are the most undervalued. The greater a company's estimated worth
compared to the current market price of its equity securities, the more
undervalued the company.
    
 
We follow the guidelines listed below for making the primary investments for the
Fund.

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, including future foreign political and economic developments,
fluctuations in foreign exchange rates and limited publicly available
information. 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 equity and fixed income
securities 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.

not necessarily identical, to those employed by the Sub-adviser with respect to
discretionary investment accounts ("Discretionary Accounts") managed by the
Sub-adviser. The chart herein shows the historical investment performance for a
composite of the Sub-adviser's Discretionary Accounts ("Sub-adviser Composite")
which were managed by the Sub-adviser in substantially the same manner as the
International Value Fund. The Sub-adviser Composite represents the total return
of all Discretionary Accounts net of the highest management fee charged and
other account fees and expenses. 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 Subchapter M of the
Internal Revenue Code. If the Discretionary Accounts included in the Sub-Adviser

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 equity securities of large, well-established
companies that generally possess the strength to withstand difficult financial
periods. Nevertheless, the value of any equity security 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 equity
securities from different economic sectors in this Fund's portfolio at a level
similar to that of the 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 of large capitalization
companies. Large capitalization companies are companies with market
capitalization over $1 billion. Equity securities will be selected and ranked

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 an
equity security's attractiveness. These scores are used to determine their
relative attractiveness. Sector weights are maintained at a similar level to
that of the Index to avoid unintended exposure to factors such as the direction
of the economy, interest rates, energy prices and inflation.

LARGE CAP VALUE FUND
    
- --------------------------------------------------------------------------------
 
   
The Large Cap Value Fund recently commenced operations and, therefore, has no
investment performance record. However, the Large Cap Value Fund will be managed
by the Sub-adviser in substantially the same manner and by the same individuals
as those who manage discretionary accounts (the "Discretionary Accounts") with
substantially similar investment objectives, policies and strategies.
    
 
   
The chart herein shows the investment performance for all Discretionary
Accounts, net of account fees and expenses. The inception dates 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 Subchapter M of 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.
    
 
   
Total fees (after expense reimbursements) for the Large Cap Value Fund are
higher than the total fees incurred by the Discretionary Accounts. Consequently,
the performance results for the Discretionary Accounts would have been lower if
the Discretionary Accounts had the same expenses as the Large Cap Value Fund.
The performance of the Discretionary Accounts has been calculated in accordance
with SEC performance standards. See "Performance and Yield Information" in the
Statement of Additional Information for a description of SEC
performance standards. THE PERFORMANCE INFORMATION HEREIN IS BASED ON THE SUB-
ADVISER'S DISCRETIONARY ACCOUNTS WHICH ARE MANAGED IN SUBSTANTIALLY THE SAME
MANNER AND BY THE SAME INDIVIDUALS AS THE LARGE CAP VALUE FUND AND DOES NOT
REFLECT THE PERFORMANCE OF THE LARGE CAP VALUE FUND ITSELF.

PORTFOLIO MANAGER

   
Michael M. Kassen and Robert I. Gendelman serve as co-managers of the Fund. Mr.
Kassen and Mr. Gendelman are Vice Presidents of the Sub-adviser and principals
of Neuberger&Berman, LLC. Messrs. Kassen and Gendelman have been associated with
the Sub-adviser since 1990 and 1994, respectively. Prior to 1994, Mr. Gendlemen
was portfolio manager for another mutual fund manager.
    
 
INVESTMENT OBJECTIVE
 
   
Seeks capital growth, through investment in equity securities of medium
capitalization companies using a value-oriented investment approach.
    
 
INVESTMENT RISK
 
   
The value of any equity security may rise or fall over long or short periods of
time. Although equity securities 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 equity securities of medium capitalization
established companies, using a value-oriented investment approach intended to
increase capital with reasonable risk. Medium capitalization companies include
companies with the characteristics of companies included in the Russell
Midcap(TM) Index. As of June 30, 1998, the largest company included in the
Russell Midcap(TM) Index had an approximate market capitalization of $10.3
billion. 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, 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.

      securities, commercial paper and certain other money market instruments,

      this when we think economic and market conditions make it too risky to
      follow its general investment guidelines.

MID CAP VALUE FUND
    
- --------------------------------------------------------------------------------
 
   
The Mid Cap Value Fund recently commenced operations and, therefore, has no
investment performance record. However, the Mid Cap Value Fund's investment
objectives, policies and strategies are substantially similar, though not
necessarily identical, to those of Neuberger&Berman Partners Fund and it is
managed by the Sub-adviser in substantially the same manner and by the same
individuals as Neuberger&Berman Partners Fund. Neuberger&Berman Partners Fund
seeks to achieve its objective by investing principally in common stocks of
medium-to large-capitalization companies. As a result, Neuberger&Berman Partners
Fund may in the future have, or in the past have had, greater exposure to larger
capitalization companies than the MidCap Value Fund will have. The chart
herein shows the investment performance for Neuberger&Berman Partners Fund for
the period April 1, 1988 through March 31, 1998, net of Neuberger&Berman
Partners Fund's fees and expenses. The date the Sub-Adviser assumed management
of Neuberger&Berman Partners Fund was January 20, 1975.
    
 
   
The Mid Cap Value Fund is subject to investment limitations, diversification
requirements and other restrictions imposed on registered mutual funds by the
1940 Act and Subchapter M of the Internal Revenue Code.
    
 
   
Total fees after (expense reimbursements) for the Mid Cap
Value Fund are higher than the total fees incurred by
Neuberger&Berman Partners Fund. Consequently, the performance results for
Neuberger&Berman Partners Fund would have been lower if Neuberger&Berman
Partners Fund had the same expenses as the Mid Cap Value Fund. The performance
of Neuberger&Berman Partners Fund has been calculated in accordance with SEC
performance standards. See "Performance and Yield Information" in the Statement

The actively-managed portion of the Fund's portfolio is managed by Kathryn Maag
Vorisek, Lloyd J. Spicer, CFA, and Terry B. French. Ms. Vorisek, Senior Vice
President and Portfolio Manager/Analyst for the Sub-adviser's small cap
discipline, is the team leader. Ms. Vorisek joined the Sub-adviser in April
1996. Previously, Ms. Vorisek was with Duff & Phelps Investment Management from
June 1989 to April 1996, Citicorp from October 1988 to June 1989, and Lehman
Brothers from July 1984 to October 1988. Mr. Spicer, Senior Vice President and
Portfolio Manager/Small Cap Advisor, joined the Sub-adviser in March 1994. Mr.
Spicer's primary responsibilities include economic forecasting to identify the
thematic components of the Sub-adviser's small cap discipline. Mr. French,
Senior Vice President and Portfolio Manager, joined the Sub-adviser in November
1997. Mr. French's primary small cap responsibilities include the analysis of
specific industry sectors. Mr. French managed private investment portfolios from
January 1991 to November 1997.
    
 
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 equity securities of small capitalization companies in
terms of revenues and/or market capitalization.
    
 
INVESTMENT RISK
 
   
A portion of this Fund's portfolio is invested in a statistically-selected
sampling of the 2000 stocks in the Russell 2000 Index (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 equity securities, 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 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 equity securities of small capitalization
companies, which are companies whose stock market capitalizations range from $50
million to $1 billion and companies included in the Index. 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 equity securities 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 Index that, as a group, should reflect its
performance. The stocks of the 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 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
in the 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
 
   
This Fund is managed by William Trimbur, Jr. Since June 1987, Mr. Trimbur has
served as Vice President and Investment Officer of American General Series
Portfolio Company, a registered open-end investment company managed by VALIC.
Mr. Trimbur has served as Portfolio Manager of the American General Series
Portfolio Company International Equities Fund since 1989, the American General
Series Portfolio Company International Government Bond Fund since 1991 and the
American General Series Portfolio Company Social Awareness Fund ("AGSPC" Social
Awareness Fund") since September 1998.
    
 
INVESTMENT OBJECTIVE
 
   
Seeks to obtain growth of capital through investment, primarily in equity
securities, in companies which meet the social criteria established for the
Fund. 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
 
   
This Fund may experience market risk, and risks associated with foreign
securities. For a discussion of these risks see "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
    
- --------------------------------------------------------------------------------
 
   
The Socially Responsible Fund recently commenced operations and, therefore, has
no investment performance record. However, the Socially Responsible Fund's
investment objectives, policies and strategies are substantially similar to
those of the AGSPC Social Awareness Fund and it is managed by VALIC in
substantially the same manner and by the same individuals as the AGSPC Social
Awareness Fund. The chart herein shows the historical investment performance for
the AGSPC Social Awareness Fund for the period of October 2, 1989 through March
31, 1998, net of AGSPC Social Awareness Fund's fees and expenses. The inception
date for the AGSPC Social Awareness Fund was October 2, 1989.
    
 
   
The AGSPC Social Awareness Fund is subject to the investment limitations,
diversification requirements and other restrictions imposed on registered mutual
funds by the 1940 Act and Subchapter M of the Internal Revenue Code.
    
 
   
Total fees (after expense reimbursements) for the Socially Responsible Fund are
higher than the total fees incurred by the AGSPC Social Awareness Fund.
Consequently, the performance results for the AGSPC Social Awareness Fund would
have been lower if the AGSPC Social Awareness Fund had the same expenses as the
Socially Responsible Fund. The performance of the AGSPC Social Awareness Fund
has been calculated in accordance with SEC performance standards. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of SEC performance standards. THE PERFORMANCE INFORMATION
HEREIN IS BASED ON THE AGSPC SOCIAL AWARENESS FUND WHICH IS MANAGED IN
SUBSTANTIALLY THE SAME MANNER AND BY THE SAME INDIVIDUALS AS THE SOCIALLY
RESPONSIBLE FUND AND DOES NOT REFLECT THE PERFORMANCE OF THE SOCIALLY
RESPONSIBLE FUND ITSELF.

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 fixed income and equity securities. The value
of an equity security can rise and fall over long and short periods of time and
involve market risks. Like equity securities, fixed income securities involve
certain risks, including interest rate risk, credit risk, market risk and risk
associated with foreign securities. This may cause the fixed income 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 fixed income and equity securities in order
to maintain the value of your principal investment and provide you with capital
growth and income over the long-term. At all times at least 25% of the Fund's
total assets are invested in fixed income senior securities. We select
securities for the Fund's portfolio by identifying fixed income and equity
securities that represent fundamental values at reasonable prices. We implement
this philosophy using a system of portfolio managers, under which a different
group of portfolio managers makes investment decisions for the fixed income and
equity portions of the Fund.

BALANCED FUND
    
- --------------------------------------------------------------------------------
 
   
The Balanced Fund recently commenced operations and, therefore, has no
investment performance record. However, the Balanced Fund's investment
objectives, policies and strategies will be substantially similar, but not
necessarily identical, to those employed by the Sub-adviser with respect to
discretionary investment accounts ("Discretionary Accounts") managed by the
Sub-adviser. Although managed in substantially the same manner as the Balanced
Fund, the Discretionary Accounts may not invest as great a percentage of their
assets in fixed income senior securities as the Balanced Fund. As a result, the
Balanced Fund may have, or may in the past have had, greater exposure to fixed
income senior securities than the Discretionary Accounts. The chart herein shows
the historical investment performance for a composite of all of the
Sub-adviser's Discretionary Accounts ("Sub-adviser Composite") which were
managed by the Sub-adviser in substantially the same manner as the Balanced
Fund. The Sub-adviser Composite represents the total return of all Discretionary
Accounts net of the highest management fee charged and other account fees and
expenses. The inception dates of the Discretionary 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 Subchapter M of the
Internal Revenue Code. If the Discretionary Accounts included in the Sub-adviser
Composite had been subject to the requirements imposed on mutual funds, their
performance might have been lower.
    
 
   
Total fees (after expense reimbursements) for the Balanced Fund are higher than
the total fees historically incurred by the Discretionary Accounts comprising
the Sub-adviser Composite. Consequently, the performance results for the
Sub-adviser Composite would have been lower if the Sub-adviser Composite had the
same expenses as the Balanced Fund.
    
 
   
The performance of the Sub-adviser Composite has been calculated in accordance
with performance presentation standards of the Association for Investment
Management and Research ("AIMR"). The AIMR method of calculating performance is
different from SEC performance standards, which are described under "Performance
and Yield Information". THE PERFORMANCE INFORMATION HEREIN IS BASED ON A
COMPOSITE OF THE SUB-ADVISER'S
    
   
DISCRETIONARY ACCOUNTS WHICH ARE

INVESTMENT OBJECTIVE
    
   
Seeks the highest possible total return and income consistent with conservation
of capital through investment in a diversified portfolio of high yielding, high
risk fixed income securities.
    
 
   
INVESTMENT RISK
    
 
   
High yielding, high risk fixed income securities are regarded as predominantly
speculative with respect to the issuer's continuing ability to meet principal
and interest payments. Because investment in lower rated fixed income securities
(commonly referred to as junk bonds) involves significantly greater credit risk,
market risk and interest rate risk than higher rated fixed income securities
achievement of the Fund's investment objective is dependent upon the
Sub-adviser's investment analysis. Accordingly, the Fund's investments may be
worth less than what the Fund paid for them. The Fund is also subject to risks
associated with foreign securities. For a discussion of these risks see "A Word
About Risk" in the prospectus.
    
 
   
INVESTMENT STRATEGY
    
 
   
The Fund invests in high yielding, high risk fixed income securities to provide
you with the highest possible total return from current income and capital gains
while preserving your investment.

Sub-adviser, Mr. Trimbur is primarily responsible for the management and trading
of non-dollar denominated bonds and equities. Mr. Trimbur managed domestic bonds
and equities for VALIC from 1987 to 1991 and has been managing foreign bonds and
equities for VALIC since 1991.
    
 
   
INVESTMENT OBJECTIVE
    
 
   
Seeks the highest possible total return and income consistent with conservation
of capital through investment in a diversified portfolio of income producing
securities.
    
 
   
INVESTMENT RISK
    
 
   
A significant portion of the Fund's investments may be in high yielding, high
risk fixed income securities that are regarded as predominantly speculative with
respect to the issuer's continuing ability to meet principal and interest
payments. Because investment in lower rated fixed income securities (commonly
referred to as junk bonds) involves significantly greater credit risk, market
risk and interest rate risk than higher rated fixed income securities
achievement of the Fund's investment objective is dependent upon the Sub-
adviser's investment analysis. Accordingly, the Fund's investments may be worth
less than what the Fund paid for them. The Fund is also subject to risks
associated with foreign securities. For a discussion of these risks see "A Word
About Risk" in the prospectus.
    
 
   
INVESTMENT STRATEGY
    
 
   
The Fund invests in a broad range of fixed income securities including
investment grade bonds, U.S. Government and agency obligations, mortgage backed
securities, high yield bonds, emerging market debt and non-dollar bonds, to
provide you with the highest possible total return from current income and
capital gains, while preserving your investment. A substantial portion of the
Fund may be invested in high yielding, high risk securities.

STRATEGIC BOND FUND
    
- --------------------------------------------------------------------------------
 
   
The Strategic Bond Fund recently commenced operations and, therefore, has no
investment performance record. However the Strategic Bond Fund's investment
objectives, policies and strategies are substantially similar to those of the
Manufacturers Investment Trust Strategic Bond Trust, which was managed by Steven
Guterman, Executive Vice President of the Sub-adviser. The chart herein shows
the historical performance for Manufacturers Investment Trust Strategic Bond
Trust net of fees and expenses. The inception date of the Manufacturers
Investment Trust Strategic Bond Trust was February 24, 1993. During Mr.
Guterman's tenure as portfolio manager of the Manufacturers Investment Trust
Strategic Bond Trust from its inception to May 1998, he was primarily
responsible for the day-to-day management of the Manufacturers Investment Trust
Strategic Bond Trust, and no other person played a significant role in achieving
the fund's performance.
    
 
   
The Strategic Bond Fund is subject to investment limitations, diversification
requirements and other restrictions imposed on registered mutual funds by the
1940 Act and Subchapter M of the Internal Revenue Code.
    
 
   
Total fees (after expense reimbursements) for the Strategic Bond Fund are higher
than the total fees incurred by the Manufacturers Investment Trust Strategic
Bond Trust. Consequently, the performance results for the Manufacturers
Investment Trust Strategic Bond Trust would have been lower if the Manufacturers
Investment Trust Strategic Bond Trust had the same expenses as the Strategic
Bond Fund. The performance of the Manufacturers Investment Trust Strategic Bond
Trust has been calculated in accordance with SEC performance standards. See
"Performance and Yield Information" in the Statement of Additional Information
for a description of SEC performance standards. THE PERFORMANCE INFORMATION
HEREIN IS BASED ON THE MANUFACTURERS INVESTMENT TRUST STRATEGIC BOND TRUST WHICH

PORTFOLIO MANAGER
 
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 investments primarily in investment grade fixed income securities 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 investments 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 fixed income securities 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
    
- --------------------------------------------------------------------------------
 
   
The Domestic Bond Fund recently commenced operations and, therefore, has no
investment performance record. However, the Domestic Bond Fund's investment
objectives, policies and strategies will be substantially similar, but not
necessarily identical, to those employed by the Sub-adviser with respect to
discretionary investment accounts ("Discretionary Accounts") managed by the
Sub-adviser. The chart herein shows the historical investment performance for a
composite of all of the Sub-adviser's Discretionary Accounts ("Sub-adviser
Composite") which were managed by the Sub-adviser in substantially the same
manner as the Domestic Bond Fund. The Sub-adviser Composite represents the total
return of all Discretionary Accounts net of the highest management fee charged
and other account fees and expenses. The inception dates of the Discretionary
Accounts 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 Subchapter M of the
Internal Revenue Code. If the Discretionary Accounts included in the Sub-adviser
Composite had been subject to the requirements imposed on mutual funds, their
performance might have been lower.
    
 
   
Total fees (after expense reimbursements) for the Domestic Bond Fund are higher
than the total fees historically incurred by the Discretionary Accounts
comprising the Sub-adviser Composite. Consequently, the performance results for
the Sub-adviser Composite would have been lower if the Sub-adviser Composite had
the same expenses as the Domestic Bond Fund.
    
 
   
The performance of the Sub-adviser Composite has been calculated in accordance
with performance presentation standards of the Association for Investment
Management and Research ("AIMR"). The AIMR method of calculating performance is
different from SEC performance standards, which are described under "Performance
and Yield Information" in the Statement of Additional Information. THE

CORE BOND FUND
    
- --------------------------------------------------------------------------------
 
   
The Core Bond Fund recently commenced operations and, therefore, has no
investment performance record. However, the Fund's investment objectives,
policies and strategies will be substantially similar to those employed by the
Sub-adviser with respect to a separately managed account of the Sub-adviser
(Separately Managed Account). The chart herein shows the historical investment
performance for the Sub-adviser's Separately Managed Account which was managed
by the Sub-adviser in substantially the same manner and by the same individuals
who manage the Core Bond Fund. The performance presented is net of management
fees (after expense reimbursements) charged by the Core Bond Fund. No other fees
and expenses were incurred by the Separately Managed Account. The inception date
of the Separately Managed Account was November 1, 1948. The Sub-adviser manages
no other accounts or funds with investment objectives, policies and strategies
that are substantially similar to those of the Core Bond Fund.
    
 
   
The Separately Managed Account was not subject to the investment limitations,
diversification requirements and other restrictions imposed on registered mutual
funds by the 1940 Act and Subchapter M of the Internal Revenue Code. If the
Separately Managed Account had been subject to the requirements imposed on
registered mutual funds, its performance might have been lower.
    
 
   
The performance of the Separately Managed Account has been calculated in
accordance with SEC performance standards. See "Performance and Yield
Information" in the Statement of Additional Information for a description of SEC
performance standards. THE PERFORMANCE INFORMATION HEREIN IS BASED ON THE

VALIC
 
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 managed by VALIC and
as Portfolio Manager of the American General Series Portfolio Company Money
Market Fund ("AGSPC Money Market Fund").
    
 
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 total 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*
    
 
   
  - Rule 144A securities (liquid)

*Limited to 10% of the Fund's net assets at all times

MONEY MARKET FUND
    
- --------------------------------------------------------------------------------
 
   
The Money Market Fund recently commenced operations and, therefore, has no
investment performance record. However, the Money Market Fund's investment
objectives, policies and strategies are substantially similar to those of the
AGSPC Money Market Fund and it is managed by VALIC in substantially the same
manner and by the same individuals as the AGSPC Money Market Fund. The chart
herein shows the historical investment performance for the AGSPC Money Market
Fund for the period of April 1, 1988 through March 31, 1998, net of AGSPC Money
Market Fund's fees and expenses. The inception date for the AGSPC Money Market
Fund was December 16, 1985.
    
 
   
The AGSPC Money Market Fund is subject to the investment limitations,
diversification requirements and other restrictions imposed on registered mutual
funds by the 1940 Act and Subchapter M of the Internal Revenue Code.
    
 
   
Total fees (after expense reimbursements) for the Money Market Fund are higher
than the total fees incurred by the AGSPC Money Market Fund. Consequently, the
performance results for the AGSPC Money Market Fund would have been lower if the
AGSPC Money Market Fund had the same expenses as the Money Market Fund. The
performance of the AGSPC Money Market Fund has been calculated in accordance SEC
performance standards. See "Performance and Yield Information" in the Statement
of Additional Information for a description of SEC performance standards. THE
PERFORMANCE INFORMATION HEREIN IS BASED ON THE AGSPC MONEY MARKET FUND WHICH IS
MANAGED IN SUBSTANTIALLY THE SAME MANNER AND BY THE SAME INDIVIDUALS AS THE
MONEY MARKET FUND AND DOES NOT REFLECT THE PERFORMANCE OF THE MONEY MARKET FUND
ITSELF.

VALIC
 
PORTFOLIO MANAGER
 
   
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 managed by VALIC. Kirsten E. Mires and Jeanie G.
Weathington assist Mr. Trimbur in the management of the Fund. Ms. Mires,
Investment Analyst, joined VALIC in October 1997. Prior to this, Ms. Mires was
an Investment Officer at Chase Securities of Texas from November 1995 to October
1997. From June 1995 to November 1995, Ms. Mires was employed as an Investment
Account Executive at Copeland Companies. Prior to this, Ms. Mires was a
Marketing Specialist at Transamerica Investment Management from July 1993 to
June 1995. Ms. Weathington, Investment Analyst, joined VALIC in April 1998.
Prior to this, Ms. Weathington was a Financial Analyst at Bank One from December
1996 to April 1998. From July 1994 to December 1996, Ms. Weathington was
Director-Portfolio Management at Goodman Financial Corporation. Prior to this,
Ms. Weathington was a Portfolio Analyst at JMC Capital Management, Inc. from
February 1994 to July 1994.
    
 
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 equity securities may offer.
    
 
INVESTMENT RISK
 
   
The Fund is a "non-diversified" investment company under the 1940 Act, which
means that the Fund is not limited in the proportion of its assets that may be
invested in the securities of a single issuer. However, in accordance with the
requirements of Subchapter M of the Code, the Fund will limit its investments so
that at the end of each quarter not more than 25% of its total assets will be
invested in a single issuer and investments representing over 5% of total assets
in one issuer will not exceed 50% of the Fund's total assets. The remaining 50%
of total assets may not include more than 5% of total assets in one issuer.
    
 
   
The allocation among the different Series Company Funds is designed to achieve
the Fund's investment objective and reduce risk. The allocation of assets within
the Fund is determined by VALIC according to fundamental quantitative analysis.
Modest shifts may be made among Underlying Series Company Funds and asset
classes based on VALIC's current outlook on financial markets and the world's
economies. Because the Fund's assets will be adjusted only periodically and only
within the investment ranges described herein, there should not be any sudden
large-scale changes in the Fund's asset allocations.
    
 
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
Fund's ability to meet its investment objective depends upon the ability of 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.
 
INVESTMENT STRATEGY
 
   
Asset allocation among the equity securities of international companies, large
capitalization companies, medium capitalization companies, small capitalization
companies and bonds is the most critical investment decision that you make as an
investor. Selecting the appropriate combination should be based on your personal
investment goals, time horizons and risk tolerance. The chart below reflects the
projected asset allocation ranges for this Fund.

Fund on the degree to which we believe the Underlying Series Company Funds, in
combination, to be appropriate for the Fund's investment objective.

TYPES OF INVESTMENTS
- --------------------------------------------------------------------------------
 
   
EQUITY SECURITIES
    
 
   
Equity securities represent an ownership position in a company. The prices of
equity securities fluctuate based on changes in the financial condition of the
issuing company and on market and economic conditions. If you own a equity
security, you own a part of the company that issued it. Companies sell equity
securities to get the money they need to grow.
    
 
   
Stocks are one type of equity security. 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, the Core
Bond 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 security. Other equity securities include
but are not limited to convertible securities, depository receipts, warrants,
rights and partially paid shares, investment company securities, real estate
securities, convertible bonds and foreign equity securities such as ADRs, GDRs
and EDRs. More information about these equity securities is set forth herein or
contained in the Statement of Additional Information.
    
 
   
FIXED INCOME SECURITIES
    
 
   
Fixed income securities include a broad array of short, medium and long term
obligations, including notes and bonds. Fixed income securities generally
involve an obligation of the issuer to pay interest on either a current basis or
at the maturity of the security and to repay the principal amount of the
security at maturity.
    
 
   
Bonds are one type of fixed income security and 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, the
Domestic Bond Fund, the High Yield Bond Fund, the Strategic Bond Fund and the
Core Bond Fund may also invest in below investment grade bonds). For a
description of investment grade bonds and below 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 that are unrated or rated below Baa3 by Moody's or BBB- by S&P (commonly
referred to as high yield, high risk or "junk bonds") are regarded, on balance,
as predominantly speculative. Changes in economic conditions or other
circumstances are more likely to weaken the issuer's capacity to pay interest
and principal in accordance with the terms of the obligation than is the case
with higher rated bonds. While such bonds may have some quality and protective
characteristics, these are outweighed by uncertainties or risk exposures to
adverse conditions. Lower rated bonds may be more susceptible to real or
perceived adverse economic and individual corporate developments than would
investment grade bonds. See "A Word about Risk -- Risks Associated with Lower
Rated Fixed Income Securities" herein.
    
 
   
For example, a projected economic downturn or the possibility of an increase in
interest rates may affect 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
    
 
ISSUED means the
Company (ISSUER) sold it
originally to the public.

OF BONDS, see the

Information.

ASSET-BACKED SECURITIES

<PAGE>   58
- --------------------------------------------------------------------------------
 
   
secondary trading market for lower rated 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 rated portfolio
securities.
    
 
   
VALIC and the Sub-advisers will not necessarily dispose of a bond when its
ratings are down graded to below investment grade.
    
 
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 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 Mid Cap Growth Fund, the Large Cap Value Fund, the Mid Cap Value Fund, the
Balanced Fund, the Domestic Bond Fund, the High Yield Bond Fund, the Strategic
Bond Fund and the Core 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, the Domestic Bond Fund, the High Yield Bond Fund, the
Strategic Bond Fund and the Core 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 and the Fund's investment
limitations see the Statement of Additional Information. Excluded from the
Fund's investment limitations however, are any Rule 144A securities which have
been determined to be liquid by the Board of Trustees, VALIC or the Sub-adviser
pursuant to Board approved guidelines. These investments can be very risky
because the Fund's ability to sell a restricted security is very limited and
Rule 144A securities deemed to be illiquid will have the effect of increasing
the amount of the Fund's investments illiquid securities.

- --------------------------------------------------------------------------------
 
   
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.
    
 
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, the High Yield
Bond Fund, the Strategic Bond Fund, the Core Bond Fund and the MidCap Value Fund
may invest in EDRs and/or GDRs. The Large Cap Growth Fund may invest in GDRs but
may not invest in EDRs.
    
 
INVESTMENT FUNDS
 
Some countries have laws and regulations that currently preclude direct foreign
investment in the securities of their companies. However, indirect foreign
investment in the securities of companies listed and traded on the stock
exchanges in these countries is permitted through investment funds which have
been specifically authorized. The International Growth Fund, the Large Cap
Growth Fund, the Small Cap Growth Fund, the International Value Fund and the Mid
Cap Value Fund may invest in investment funds.
 
FOREIGN CURRENCY
 
   
All of the Funds, except the Lifestyle Funds, the 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 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 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
 
   
The Funds may invest in the securities of other open-end or closed-end
investment companies subject to the limitations imposed by the 1940 Act. A Fund
will indirectly bear its proportionate share of any management fees and other
expenses paid by an investment company in which it invests.

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 it expires, you must sell to Mr. Smith 10 shares of stock X at
$25.00 per share.
    
 
Put Option
 
Or, you can buy an option from Mr. Smith that gives you the right to sell him 10
shares of X stock at $25.00 per share anytime between now and six weeks from
now. In this example, you believe stock X will be selling for less than $25.00
per share between now and then. Mr. Smith thinks it will be selling for more.
 
Or, you can sell an option to Mr. Smith that gives him the right to sell to you
10 shares of X stock at $25.00 per share anytime between now and six weeks from
now. In this example, he believes stock X will be selling for less than $25.00
per share between now and then.
 
The Funds use stock and bond futures to invest cash and cash equivalents. When
certain levels are reached the Fund will sell the futures and buy stocks or
bonds.
 
   
All of the Funds except the Lifestyle Funds, the Money Market Fund, the Mid Cap
Growth Fund, and the International Growth Fund may invest in one or more of the
following types of futures and options:
    
 
   
  - Write (sell) 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 (sell) covered call options and purchase exchange traded put and call
    options on financial futures contracts.
    
 
   
  - Write (sell) 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.

Fund, the Small Cap Value Fund, the International Value Fund, the Balanced Fund,

<PAGE>   61
 
- --------------------------------------------------------------------------------
 
   
Bond Fund, the Core Bond Fund and the Small Cap Growth 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). A Fund 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, including manager risk, 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 herein. 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.
    
 
   
Risks Associated with Lower Rated Fixed Income Securities
    
 
   
Certain of the Funds also may purchase fixed income securities that are rated
below investment grade. Fixed income securities rated below BBB- by S&P or Baa3
by Moody's are considered to be below investment grade. Fixed income securities
with a below investment grade rating present a comparatively greater risk of
default in the timely payment of interest and principal than fixed income
securities rated as investment grade.
    
 
   
The lower rated but higher yielding fixed income securities purchased by the
Funds may be issued in connection with corporate restructurings, such as
leveraged buyouts, mergers, acquisitions, debt recapitalizations, or similar
events. In addition, high yield fixed income securities are often issued by
smaller, less creditworthy companies or by companies with substantial debt. The
securities ratings by Moody's and S&P are based largely on the issuer's
historical financial condition and the rating agency's investment analysis at
the time of the rating. As a result, the rating assigned to a security does not
necessarily reflect the issuer's current financial condition, which may be
better or worse than the rating indicates. Credit ratings are only one factor a
Sub-adviser relies on in evaluating lower-rated fixed income securities. The
analysis by the Sub-adviser of a lower rated security may also include
consideration of the issuer's experience and managerial strength, changing
financial condition, borrowing requirements or debt maturity schedules,
regulatory concerns, and responsiveness to changes in business conditions and
interest rates. The Sub-adviser also may consider relative values based on
anticipated cash flow, interest or

dividend coverage, balance sheet analysis, and earnings prospects.
    
 
   
The market for lower rated fixed income securities is relatively new and until
recently its growth has paralleled a long economic expansion. Past experience,
therefore, may not provide an accurate indication of future performance of this
market, particularly during an economic recession. An economic downturn or
increase in interest rates is likely to have a greater negative effect on the
ability of the issuers to pay principal and interest, meet projected business
goals, and obtain additional financing. These circumstances also may result in a
higher incidence of defaults compared to higher rated securities. As a result,
adverse changes in economic conditions and increases in interest rates may
adversely affect the market for lower rated fixed income securities, the value
of such securities in a Fund's portfolio, and, therefore, the Fund's net asset
value. As a result, investment in such Fund is more speculative than investment
in a fund that invests primarily in higher rated fixed income securities.
    
 
   
Although certain Funds intend generally to purchase lower rated securities that
have secondary markets, these markets may be less liquid and less active than
markets for higher rated securities. These factors may limit the ability of a
Fund to sell lower rated securities at their expected value. Adverse publicity
and investor perceptions, whether or not based on fundamental analysis, may
decrease the values and liquidity of lower rated fixed income securities,
especially in a thinly traded market. If market quotations are not readily
available for the Fund's lower rated or nonrated securities, these securities
will be valued by a method the Sub-adviser believes accurately reflects fair
value. Judgment plays a greater role in valuing lower rated fixed income
securities than it does in valuing securities for which more extensive
quotations and last sale information are available.
    
 
   
See the Appendix to the prospectus for a description for corporate bond ratings.
    
 
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, EDRs and GDRs 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.
 
                                       58
<PAGE>   63
 
- --------------------------------------------------------------------------------
 
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 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. However, the Series Company offers shares of the Funds
only to registered and unregistered separate accounts of VALIC, and its
affiliates, or employee thrift plans maintained by VALIC or American General
Corporation.
 
The Series Company was organized on May 6, 1998, under the laws of the state of
Delaware as a business trust, and presently is authorized to sell 18 series.
Each of these series is authorized to issue an unlimited number of shares of
beneficial interest, par value $0.01 per share.
 
   
The Series Company does not contemplate holding regular meetings of shareholders
to elect Trustees or otherwise. However, the holders of 10% or more of the
outstanding shares of the Series Company may by written request require a
meeting to consider the removal of Trustees by a vote of two-thirds of the
shares then outstanding cast in person or by proxy at such meeting. The Series
Company will assist such holders in communicating with other shareholders of the
Series Company to the extent required by the 1940 Act. More detailed information
concerning the Series Company is set forth in the Statement of Additional
Information.
    
 
The Series Company's Declaration of Trust provides that no Trustee, officer or
shareholder of the Series Company shall be held to any personal liability, nor
shall resort be had to their private property for the satisfaction of any
obligation or liability of the Series Company but the assets of the Fund only
shall be liable.
 
   
As a participant, you do not directly buy shares of the Funds that make up the
Series Company. Instead, you buy units in either a registered or unregistered
separate account of VALIC or of its affiliates. When you buy these units, you
specify which Funds you want the separate account to invest your money in. The
separate account, in turn, buys the shares of the Funds according to your
instructions. Share certificates are not available. See your contract prospectus
for more information on the separate account associated with your contract.
    
 
When the separate accounts buy, sell, or transfer shares of the Funds, they do
not pay any charges related to these transactions.
 
   
None of the Funds currently foresees any disadvantages to participants arising
out of the fact that it may offer its shares to separate accounts of various
insurance companies to serve as the investment medium for their variable annuity
and variable life insurance contracts. Nevertheless, the Board of Trustees
intends to monitor events in order to identify any material irreconcilable
conflicts which may possibly arise and to determine what action, if any, should
be taken in response to such conflicts. If such a conflict were to occur, one or
more insurance companies' separate accounts might be required to withdraw their
investments in one or more Funds and shares of another Fund may be substituted.
This might force a Fund to sell portfolio securities at disadvantageous prices.
In addition, the Board of Trustees may refuse to sell shares of any Fund to any
separate account or may suspend or terminate the offering of shares of any Fund
if such action is required by law or regulatory authority or is in the best
interests of the shareholders of the Fund.
    
 
As distributor, VAMCO sells shares of the Funds to the separate accounts. VAMCO
is a wholly owned subsidiary of VALIC and acts as a distributor under an
agreement it has with the Series Company. VAMCO does not charge the Series
Company or the separate accounts for its services. Also, VAMCO is not required
to sell a minimum number of shares to the separate accounts.
 
   
VAMCO sends orders to buy, sell or transfer shares to the Series Company's
transfer agent daily. The price of any share affected by the request is the next
net asset value calculated after the order is received.
    
 
For more information on how to participate, see your contract prospectus.
 
NET ASSET VALUE OF THE SERIES COMPANY SHARES
 
How Net Asset Value is Calculated
 
Here is how the Series Company calculates the net asset value of each Fund's
shares:
 
   
<TABLE>
<S>  <C>                           <C>  <C>
Step 1:
     Total value of the Fund's
     assets* (including money           The Fund's
     owed to the Fund but not yet       Total Net Asset
     collected)                      =  Value
- -    The Fund's liabilities
     (including money owed by the
     Fund but not yet paid)
 
Step 2:
     The Fund's total net asset
     value (from Step 1)
/    The total number of the
     Fund's shares that are             NET ASSET VALUE
     outstanding.                    =  PER SHARE
</TABLE>
    
 
- ---------------
 
   
* The Series Company uses the fair market value of a 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.
 
THE VARIABLE ANNUITY
MARKETING COMPANY
(VAMCO) acts as the
Series Company's
distributor.
 
                                       60
<PAGE>   65
- --------------------------------------------------------------------------------
 
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, the separate accounts send orders to the Series Company
to buy, sell, or transfer shares based on requests received from participants.
    
 
   
ADMINISTRATIVE SERVICE AGREEMENT
    
 
   
The Series Company has entered into an Administrative Service Agreement
("Service Agreement") with VALIC for the provision of recordkeeping and
shareholder services to retirement and employee benefit plans. Under the terms
of the Service Agreement, the Series Company pays VALIC monthly, a fee equal to
0.25% of the aggregate net asset value of each Fund, other than the Lifestyle
Funds, on an annual basis. Under the Service Agreement, VALIC provides
recordkeeping services, including the establishment and maintenance of plan and
participant accounts and records; participant services, including the provision
of customer service representatives to respond to participant inquiries and
process telephone transactions; and plan services, including the production of
plan documentation and summary plan descriptions. Fees paid under the Service
Agreement may be for shareholder service and the maintenance of accounts and,
therefore, may constitute "service fees" for purposes of applicable rules of the
National Association of Securities Dealers, Inc.
    
 
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 a Fund. Each Fund pays dividends from net
investment income occasionally. Dividends from net investment income are
automatically reinvested for you into additional shares of the Fund. Each Fund,
except the Money Market Fund pays dividends quarterly. The Money Market Fund
pays dividends daily.
    
 
Distributions from Capital Gains
 
When a Fund sells a security for more than it paid for that security, a capital
gain results. Once a year, each Fund pays distributions from capital gains, as
long as total capital gains exceed total capital losses. Distributions from
capital gains are automatically reinvested for you into additional shares of the
Fund.
 
DIVERSIFICATION
 
Each Fund's diversification policy limits the amount that the Fund may invest in
certain securities. Each Fund's diversification policy is also designed to
comply with the diversification requirements of the Internal Revenue Code (the
"Code") as well as the 1940 Act.
 
All of the Funds, except the Lifestyle Funds, may, with respect to 75% of their
total assets, invest up to 5% of their total assets in a single issuer. An
issuer, or "company" does not include the U.S. Government or agencies of the
U.S. Government according to the Code and the 1940 Act. For diversification
purposes, repurchase agreements are considered to be issued by the U.S.
Government if backed by U.S. Government securities. Also, these Funds may not
own more than 10% of the voting securities of a company.
 
   
The Lifestyle Funds are "non-diversified" under the 1940 Act, which means that
the Lifestyle Funds are not limited in the proportion of their assets that may
be invested in the securities of a single issuer. However, in accordance with
the requirements of Subchapter M of the Code, the Lifestyle Funds will limit
their investments so that at the end of each quarter not more than 25% of their
total assets will be invested in a single issuer and investments representing
over 5% of total assets in one issuer do not exceed 50% of total assets of a
Lifestyle Fund. The remaining 50% of total assets may not include more than 5%
of total assets in one issuer.
    
 
Also, the Money Market Fund may not invest more than 5% of its total assets in
any company rated as "second tier" by a national rating service (as described in
Types of Investments).
 
TAXES
 
By paying out all earnings as described in the Dividends and Capital Gains
section above and by complying with the diversification requirements under the
Code, each Fund expects to qualify as a Registered Investment Company (RIC)
under Subchapter M of the Code. By qualifying as a RIC the Fund will not have to
pay federal income taxes.
 
VOTING RIGHTS
 
One Vote Per Share
 
Each outstanding share has one vote on all matters that shareholders vote on. As
a participant, you vote on these matters indirectly by voting your units. The
way you vote your units as a participant depends on your contract. See your
contract prospectus for specific details.
 
When a matter comes up for vote, the separate account will vote its shares in
the same proportion
 
See the Statement of
Additional information and
your contract prospectus for
further tax discussions. You
should also consult your tax
advisor before investing.
 
                                       61
<PAGE>   66
- --------------------------------------------------------------------------------
 
as the unit votes it actually receives. If VALIC determines that it may, under
the current interpretation of the 1940 Act, vote shares directly instead of
voting through its units, it may decide to vote that way.
 
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
 
   
VALIC is in the process of modifying its systems to achieve Year 2000 readiness.
This endeavor is directed and managed by VALIC and monitored by the parent
company, American General Corporation. VALIC has developed clearly defined and
documented plans that have been implemented to minimize the risk of significant
negative impact on its operations.
    
 
   
These plans include the following activities: (1) perform an inventory of
VALIC's information technology and non-information technology systems; (2)
assess which items in the inventory may expose VALIC to business interruptions
due to Year 2000 issues; (3) test systems for Year 2000 readiness; (4) reprogram
or replace systems that are not Year 2000 ready; and (5) return the systems to
operation. VALIC expects to complete the forgoing activities for all critical
business systems relevant to the Series Company by December 1998. Accordingly,
VALIC has no contingency plans because any open Year 2000 issues may be
addressed in 1999.
    
 
   
In addition, the Series Company and VALIC have business relationships with
various third parties, each of which must also be Year 2000 ready. Therefore,
VALIC's plans also include assessing and attempting to mitigate the risks
associated with the potential failure of third parties to achieve Year 2000
readiness. Due to the various stages of the third parties' Year 2000 readiness,
VALIC's efforts in this regard will extend through 1999.
    
 
   
Through June 30, 1998 VALIC has incurred and expensed $13 million (pretax)
related to Year 2000 readiness, including $6.5 million incurred during the first
six months of 1998. VALIC currently anticipates that it will incur future costs
of $3 million (pretax) for additional internal staff, third party vendors, and
other expenses to achieve Year 2000 readiness.
    
 
   
Due to the magnitude and complexity of this project, risks and uncertainties
exist. If conversion of VALIC's systems is not completed on a timely basis (due
to non-performance by significant third-party vendors or other unforeseen
circumstances), or if significant third parties fail to achieve Year 2000
readiness on a timely basis, the Year 2000 issue could have a material adverse
impact on the operations of VALIC and the Series Company.
    
 
REPORTS
 
The Series Company sends Annual Reports containing audited financial statements,
Semi-Annual Reports containing unaudited financial statements, and proxy
materials to contract owners or participants. Also, the Series Company includes
an Annual Report with each Statement of Additional Information it sends out.
 
If you have any questions about the Annual or Semi-Annual Reports, call or write
to the Series Company at the phone number / address found on the cover page of
this prospectus.

APPENDIX -- DESCRIPTION OF BOND RATINGS
    
- --------------------------------------------------------------------------------
 
   
MOODY'S INVESTORS SERVICE
    
 
   
Aaa: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge". Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.
    
 
   
Aa: Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds. They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuation of protective elements
may be of greater amplitude or there may be other elements present which make
the long-term risks appear somewhat larger than in Aaa securities.
    
 
   
A: Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper medium grade obligations. Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.
    
 
   
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; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during other good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
    
 
   
B: Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
    
 
   
Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
    
 
   
Ca: Bonds which are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.
    
 
   
C: Bonds which are rated C are the lowest rated class of bonds and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.
    
 
   
Nonrated: Where no rating has been assigned or where a rating has been suspended
or withdrawn, it may be for reasons unrelated to the quality of the issue.
    
 
   
Should no rating be assigned, the reason may be one of the following:
    
 
   
1. An application for rating was not received or accepted.
    
 
   
2. The issue or issuer belongs to a group of securities that are not rated as a
matter of policy.
    
 
   
3. There is a lack of essential data pertaining to the issue or issuer.
    
 
   
4. The issue was privately placed, in which case the rating is not published in
Moody's publications.
    
 
   
Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.
    
 
   
Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believe
possess the strongest investment attributes are designated by the symbols Aa 1,
A 1, Baa 1, Ba 1 and B 1.
    
 
   
STANDARD & POOR'S CORPORATION
    
 
   
AAA: Debt rated AAA has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.
    
 
   
AA: Debt rated AA has a very strong capacity to pay interest and repay principal
and differs from the higher rated issues only in small degree.
    
 
   
A: Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.
    
 
   
BBB: Debt rated BBB is regarded as having an adequate capacity to pay interest
and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.
    
 
   
BB, B, CCC, CC, C: Debt rated BB, B, CCC, CC and C is regarded, on balance, as
predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and C the highest degree of speculation. While such
debt will likely have some quality and protective characteristics,
    
 
                                       63
<PAGE>   68
 
   
these are outweighed by large uncertainties or major risk exposures to adverse
conditions.
    
 
   
CI: The rating CI is reserved for income bonds on which no interest is being
paid.
    
 
   
D: Debt rated D is in default, and payment of interest and/or repayment of
principal is in arrears.
    
 
   
Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
    
 
   
NR: Indicates that no rating has been requested, that there is insufficient
information on which to base a rating, or that Standard & Poor's does not rate a
particular type of obligation as a matter of policy.
    
 
   
PREFERRED STOCK RATINGS
    
 
   
Both Moody's and Standard & Poor's use the same designations for corporate bonds
as they do for preferred stock, except in the case of Moody's preferred stock
ratings, the initial letter rating is not capitalized. While the descriptions
are tailored for preferred stocks, the relative quality distinctions are
comparable to those described above for corporate bonds.
    
 
                                       64
<PAGE>   69
 
   
APPENDIX -- DESCRIPTION OF COMMERCIAL PAPER RATINGS
    
- --------------------------------------------------------------------------------
 
   
A AND PRIME COMMERCIAL PAPER RATINGS.
    
 
   
Commercial paper rated A by S&P has the following characteristics: Liquidity
ratios are adequate to meet cash requirements. Long-term senior debt is rated
"A" or better, although, in some cases "BBB" credits may be allowed. The issuer
has access to at least two additional channels of borrowing. Basic earnings and
cash flow have an upward trend with allowance made for unusual circumstances.
Typically, the issuer's industry is well established and the issuer has a strong
position within the industry. The reliability and quality of management are
unquestioned. The rating is described by S&P as the investment grade category,
the highest rating classification. Relative strength or weakness of the above
factors determine whether the issuer's commercial paper is rated A-1, A-2 or
A-3.
    
 
   
Among the factors considered by Moody's in assigning commercial paper ratings
are the following: (1) evaluation of the management of the issuer; (2) economic
evaluation of the issuer's industry or industries and an appraisal of
speculative-type risks which may be inherent in certain areas; (3) evaluation of
the issuer's products in relation to competition and customer acceptance; (4)
liquidity; (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten years; (7) financial strength of a parent company and the
relationships which exist with the issuer; and (8) recognition by the management
of obligations which may be present or may arise as a result of public interest
questions and preparations to meet such obligations. Relative differences in
strengths and weaknesses in respect of these criteria establish a rating in one
of three classifications. The rating Prime-1 is the highest commercial paper
rating assigned by Moody's. Its other two ratings, Prime-2 and Prime-3 are
designated Higher Quality and High Quality, respectively.

                        GENERAL INFORMATION AND HISTORY
 
     American General Series Portfolio Company 3 (the "Series Company") was
organized as a Delaware business trust on May 6, 1998 by VALIC and is registered
under the Investment Company Act of 1940, as amended, (the "1940 Act") as an
open-end, management investment company. Pursuant to an Investment Advisory
Agreement with the Series Company and subject to the authority of the Series
Company's Board of Trustees, VALIC serves as the Series Company's investment
adviser and conducts the business and affairs of the Series Company.
Additionally, VALIC has engaged investment sub-advisers to provide investment
sub-advisory services for each Fund other than the American General Socially
Responsible Fund, the American General Money Market Fund, the American General
Conservative Growth Lifestyle Fund, the American General Moderate Growth
Lifestyle Fund and the American General Growth Lifestyle Fund, subject to
VALIC's control, direction and supervision. The Series Company consists of
eighteen separate investment portfolios (hereinafter collectively referred to as
the "Funds" or individually as a "Fund"), each of which is, in effect, a
separate mutual fund issuing its own separate class of shares of beneficial
interest.
 
     The Series Company issues shares of interest of each Fund to registered and
unregistered separate accounts of VALIC and its affiliates to fund variable
annuity or variable life contracts (the "Contracts"). Currently the Series
Company acts as an investment vehicle for assets of VALIC's Separate Account, a
unit investment trust registered as an investment company under the 1940 Act.
Additionally, retirement plans maintained by VALIC and American General
Corporation may own shares of certain of the Funds.
 
   
     The Series Company and VALIC have Codes of Ethics which establish for their
officers, directors or trustees, 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 mutual fund with similar
investment objectives, policies and strategies as the Fund that is currently
managed by the same individuals; (ii) an unregistered discretionary account of
the Sub-adviser with similar investment objectives, policies and strategies that
is managed by the same individuals; and/or (iii) a composite of such registered
management investment companies or unregistered discretionary accounts. The
inception date indicated is that of the other mutual fund, account or composite.
See the Prospectus for detailed information relating to the mutual fund,
unregistered discretionary account or composite.
    
 
   
     The total return of a Fund ("Average Annual Total Return"), is the total
return of a Fund before expenses ("Portfolio Total Return"). The Series Company
may compare Portfolio Total Return to the total return of the Fund's benchmark
index ("Index Total Return"). The difference between Portfolio Total Return and
Index Total Return is referred to as "tracking difference." Tracking difference
represents the amount that the return on the investment portfolio (which results
from VALIC or the Sub-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
 
                                        4
<PAGE>   77
 
     Where:
 
<TABLE>
                 <S>     <C>
                 P     = A hypothetical initial Purchase Payment of $1,000.
                 T     = Average annual total return.
                 n     = Number of years.
                 ERV =   Ending redeemable value of a hypothetical $1,000 Purchase
                         Payment made at the beginning of the first period.
</TABLE>
 
     Average Annual Total Return reflects the deduction of Fund expenses and
assumes that all dividends and distributions are reinvested when paid.
 
PORTFOLIO TOTAL RETURN
 
     Portfolio Total Return quotations for periods of 1, 3, 5, and 10 years, or,
since inception are calculated by adding to the Average Total Annual Return
(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 American General Domestic Bond Fund, the American General High Yield
Bond Fund, the American General Strategic Bond Fund and the American General
Core 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.

                            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. Also,
certain of the Funds have non-fundamental investment restrictions, which may be
changed by the Series Company's Board of Trustees without shareholder approval.
    
 
   
     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. However, percentage limitations for illiquid securities and borrowings
apply at all times.

     purchased by institutional investors, or (ii) the entry into repurchase
     agreements or reverse repurchase agreements. The Fund may lend its

     regard to such limitation to the extent permitted by (i) the 1940 Act, as
     amended from time to time, (ii) the rules and

     1940 Act.
    
 
   
 (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, provided,

     not apply to securities issued or guaranteed by 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%

     securities or (ii) by engaging in repurchase agreements.
 
 (6) Purchase real estate unless acquired as a result of the ownership of
     securities or instruments, but this restriction shall not prohibit the Fund
     from purchasing securities issued by entities or investment vehicles that

     real estate or interests therein.
 
 (7) Issue senior securities, except as permitted under the 1940 Act.

     and regulations promulgated by the SEC under the 1940 Act, as amended from
     time to time, or (iii) an exemption or other relief from the provisions of

     not constitute the purchase of securities on margin and shall not be deemed
     to violate the foregoing limitation.

     5% of the Fund's net assets, the Fund will not purchase additional
     securities.

    permitted by (i) the 1940 Act, as amended from time to time, (ii) the rules

                              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 U.S.
Government security or a security rated in the highest rating category by the
requisite NRSROs (Nationally Recognized Statistical Rating Organization) (except
for the International Growth Fund, the International Value Fund, the Strategic
Bond Fund and the High Yield Bond 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 and must be determined to
present minimal credit risk. Repurchase agreements
    
 
                                       22
<PAGE>   95
 
   
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 result is 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 International Growth Fund, the Large Cap Growth
Fund, the Small Cap Growth Fund, the Large Cap Value Fund, the Mid Cap Value
Fund, the Small Cap Value Fund, the High Yield Bond Fund, the Balanced Fund, the
International Value Fund, the Domestic Bond Fund, the Strategic Bond Fund and
the Core Bond Fund).
    
 
LENDING PORTFOLIO SECURITIES
 
   
     For purposes of realizing additional income, each Fund, except the
Lifestyle Funds, may make secured loans of its portfolio securities. Securities
loans are made to broker-dealers and other financial institutions approved by
State Street Bank and Trust Company (the "Custodian"), custodian to the Funds
and pursuant to agreements requiring that the loans be continuously secured by
collateral at least equal at all times to the loaned securities marked to market
on a daily basis. VALIC will monitor the activities of the Custodian as
authorized by the Board of Trustees. The collateral received will consist of
cash, U.S. government securities, letters of credit or such other collateral as
permitted by interpretations or rules of the Securities and Exchange Commission
("SEC"). While the securities are on loan, the Funds will continue to receive
the equivalent of the interest or dividends paid by the issuer on the
securities, as well as interest on the investment of the collateral or a fee
from the borrower.
    
 
   
     Any loan of portfolio securities by any Fund will be callable at any time
by the lending Fund upon notice of five business days. When voting or consent
rights which accompany loaned securities pass to the borrower, the lending Fund
will call the loan, in whole or in part as appropriate, to permit the exercise
of such rights if the matters involved would have a material effect on that
Fund's investment in the securities being loaned. If the borrower fails to
maintain the requisite amount of collateral, the loan will automatically
terminate, and the lending Fund will be permitted to use the collateral to
replace the securities while holding the borrower liable for any excess of
replacement cost over collateral. As with any extensions of credit, there are
risks of delay in receiving additional collateral or in the recovery of the
securities or, in some cases, even loss of rights in the collateral should the
borrower of the securities fail financially. However, these loans of portfolio
securities will be made only when the custodian, 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
    
 
                                       23

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. Those Funds that may enter into reverse repurchase
agreements 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.
 
   
     To the extent that convertible securities are intended by a Fund to be
equity securities, the following equity quality criteria typically are
considered: industry prospects (growth rate, competitive pressures,
supply/demand characteristics), market valuations (including price-to-book
ratios, price-earnings ratios and return on equity), company profile (suppliers,
competitors, end-users and customers), discretionary cash flow and quality of
management. To the extent that convertible securities are intended by a Fund to
be fixed income securities, the quality criteria typically applied by the Fund
to investments in fixed income securities (i.e., Moody's and S&P ratings) are
applied.
    
 
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 the following
depository receipts: American Depository Receipts (ADRs), European Depositary
Receipts (EDRs) and Global Depository Receipts (GDRs). Depository receipts that
are denominated in U.S. dollars are not considered foreign securities in
determining compliance with the Mid Cap Value Fund's investment restrictions.
    
 
   
     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, certain Funds may invest in other types of depositary securities such
as international depository receipts, global de-
    
 
                                       24
<PAGE>   97
 
   
pository 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, 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.
    
 
   
INTERNATIONAL BONDS
    
 
   
     Certain Funds also may invest in international bonds, which include U.S.
dollar-denominated bonds issued by foreign corporations for which the primary
trading market is in the United States ("Yankee Bonds"), or for which the
primary trading market is abroad ("Euro Bonds"). International bonds may involve
special risks and considerations not typically associated with investing in U.S.
companies, including differences in accounting, auditing and financial reporting
standards; generally higher commission rates on foreign portfolio transactions;
the possibility of nationalization, expropriation or confiscatory taxation;
adverse changes in investment or exchange control regulations (which may include
suspension of the ability to transfer currency from a country); and political
instability which could affect U.S. investments in foreign countries.
Additionally, dispositions of foreign securities and dividends and interest
payable on those securities may be subject to foreign taxes, including
withholding taxes. Foreign securities often trade with less frequency and volume
than domestic securities and, therefore, may exhibit greater price volatility. A
Fund's investment in international bonds also may be affected either unfavorably
or favorably by fluctuations in the relative rates of exchange between
currencies of different nations, by exchange control regulations and by
indigenous economic and political developments.
    
 
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
 
                                       25
<PAGE>   98
 
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 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 certain of 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
 
                                       26
<PAGE>   99
 
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.
 
   
FIXED INCOME SECURITIES
    
 
   
     Fixed income 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 fixed income
securities are considered to have a very strong capacity to pay principal and
interest. Fixed income securities are considered investment grade if they are
rated, for example, at least Baa by Moody's or BBB by S&P or their equivalents
by any other NRSRO or, if not rated, are determined to be of equivalent
investment quality. Investment grade fixed income securities are regarded as
having an adequate capacity to pay principal and interest. Lower rated
securities, for example, Ba 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.
    
 
   
     The maturity of fixed income 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
fixed income securities, while an increase in interest rates generally reduces
their value.
    
 
   
LOWER RATED FIXED INCOME SECURITIES
    
 
   
     Issuers of lower rated or non-rated securities ("high yield" securities,
commonly known as "junk bonds") may be highly leveraged and may not have
available to them more traditional methods of financing. Therefore, the risks
associated with acquiring the securities of such issuers generally are greater
than is the case with higher rated securities. For example, during an economic
downturn or a sustained period of rising interest rates, issuers of high yield
securities may be more likely to experience financial stress, especially if such
issuers are highly leveraged. During such periods, such issuers may not have
sufficient revenues to meet their interest payment obligations. The issuer's
ability to service its debt obligations also may be adversely affected by
specific issuer developments, or the issuer's inability to meet specific
projected business forecasts, or the unavailability of additional financing. The
risk of loss due to default by the issuer is significantly greater for the
holders of lower rated securities because such securities may be unsecured and
may be subordinated to other creditors of the issuer.
    
 
   
     Lower rated securities frequently have call or redemption features which
would permit an issuer to repurchase the security from a Fund. If a call were
exercised by the issuer during a period of declining interest rates, a Fund
likely would have to replace such called security with a lower yielding
security, thus decreasing the net investment income to a Fund and dividends to
shareholders.
    
 
   
     A Fund may have difficulty disposing of certain lower rated securities
because there may be a thin trading market for such securities. The secondary
trading market for high yield securities is generally not as liquid as the
secondary market for higher rated securities. Reduced secondary market liquidity
may have an adverse impact on market price and a Fund's ability to dispose of
particular issues when necessary to meet a Fund's liquidity needs or in response
to a specific economic event such as a deterioration in the creditworthiness of
the issuer.
    
 
   
     Adverse publicity and investor perceptions, which may not be based on
fundamental analysis, also may decrease the value and liquidity of lower rated
securities, particularly in a thinly traded market. Factors adversely affecting
the market value of lower rated securities are likely to adversely affect a
Fund's net asset value. In addition, a Fund may incur additional expenses to the
extent it is required to seek recovery upon a default on a portfolio holding or
participate in the restructuring of the obligation.
    
 
   
     Finally, there are risks involved in applying credit ratings as a method
for evaluating lower rated fixed income securities. For example, credit ratings
evaluate the safety of principal and interest payments, not the market risks
involved in lower rated fixed income securities. Since credit rating agencies
may fail to change the credit ratings in a timely manner to reflect subsequent
events, the Sub-adviser will monitor the issuers of lower rated fixed income
securities in a Fund to determine if the issuers will have sufficient cash flow
and profits to
    
 
                                       27
<PAGE>   100
 
   
meet required principal and interest payments, and to assure the debt
securities' liquidity within the parameters of the Fund's investment policies.
The Sub-adviser will not necessarily dispose of a portfolio security when its
ratings have been changed.
    
 
ZERO COUPON BONDS
 
   
     The Large Cap Value Fund, the Mid Cap Value Fund, the Balanced Fund, the
High Yield Bond Fund, the Strategic Bond Fund, the US Core Bond Fund and the
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 Internal Revenue Code
(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 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 war-
                                       28
<PAGE>   101
 
rants 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 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.
                                       29
<PAGE>   102
 
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 1940 Act, and (iv) are not
registered or regulated under the 1940 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.
 
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
 
                                       30
<PAGE>   103
 
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 the
International Growth Fund, the Small Cap Growth Fund, the Large Cap Growth Fund,
the Large Cap Value Fund, the Mid Cap Value Fund, the Small Cap Value Fund, the
High Yield Bond Fund, the Balanced Fund, the International Value Fund, the
Domestic Bond Fund, the Strategic Bond Fund and the Core Bond Fund), of the
value of their net 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 International Growth Fund, the
Small Cap Growth Fund, the Large Cap Growth Fund, the Large Cap Value Fund, the
Mid Cap Value Fund, the Small Cap Value Fund, the High Yield Bond Fund, the
Balanced Fund, the International Value Fund, the Domestic Bond Fund, the
Strategic Bond Fund and the Core Bond Fund) of its net assets in illiquid
securities. Excluded from the Funds' investment limitations, however, are any
Rule 144A securities that have been determined to be liquid by the Board of
Trustees, VALIC or the Sub-adviser pursuant to Board approved guidelines.
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 net assets in illiquid securities.
Invest-

ing in Rule 144A securities could have the effect of
increasing the amount of the Funds' investments in illiquid securities if
qualified institutional buyers are unwilling to purchase such securities. Each
Fund other than the Lifestyle Funds, may invest in Rule 144A securities (in
accordance with each Fund's investment restrictions as listed in the prospectus)
that have been determined to be liquid by Board approved guidelines.
    
 
OPTIONS ON SECURITIES AND SECURITIES INDICES
 
   
     Each Fund, other than the Large Cap Growth Fund, the Mid Cap Growth Fund,
the International Growth Fund, the Lifestyle Funds 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
Lifestyle Funds, the International Growth Fund, the International Value Fund,
the Mid Cap Value 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 de-
    
 
                                       32
<PAGE>   105
 
clines 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 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, the
Small Cap Growth Fund, the High Yield Bond Fund, the Strategic Bond Fund and the
Core Bond 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 Large Cap Growth Fund, the Lifestyle Funds 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
                                       33
<PAGE>   106
 
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 security, 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 Lifestyle Funds 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, the Small Cap
Growth Fund, the High Yield Bond Fund, the Strategic Bond Fund and the Core Bond
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 Mid Cap Value Fund, the Lifestyle Funds 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, the High Yield Bond Fund, the Strategic Bond Fund
and the Core Bond 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 ele-
    
                                       35
<PAGE>   108
 
ments 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, 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
the 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 Mid Cap Value Fund, the Lifestyle Funds 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. 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
 
                                       36
<PAGE>   109
 
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 may be able, by adjusting
investment strategy in the
                                       37
<PAGE>   110
 
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, or the Sub-adviser'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 or the Sub-adviser'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, or the
Sub-adviser will use financial futures 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 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 certain of the Funds will be
limited to: (i) obligations of, or guaranteed by, a foreign government, its
agencies or instrumentalities;
    
                                       38
<PAGE>   111
 
(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 primary 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. 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 August 26, 1998, that was
approved by the Board of Trustees on August 26, 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 and
expenses of servicing shareholder accounts (e.g., daily calculation of the net
asset value). The Series Company allocates advisory fees, SEC filing fees,
interest expenses and state filing fees, if any, to the Fund that incurs such
charges and allocates all other expenses among the Funds based on the net assets
of each Fund in relation to the net assets of the Series Company.
    
 
   
     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 Agreement
requires 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 August 26, 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
                                       39

approved, after the initial two year term, 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 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 August 26, 1998 with
each Sub-adviser, VALIC has engaged American General Investment Management, L.P.
("AGIM") to provide sub-advisory services to the High Yield Bond Fund, the
Strategic Bond Fund and the Core Bond Fund and Bankers Trust Company ("Bankers
Trust") to provide sub-advisory services for 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 sub-advisory 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. AGIM, 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").
    
 
   
     In selecting Sub-advisers, the Series Company's 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-adviser's 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 Series Company was issued an exemptive order by the SEC on September
[9], 1998 for an exemption (the "Exemption") from certain provisions of the 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
    
                                       40
<PAGE>   113
 
   
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 initial shareholder of each Fund on August 26, 1998, consented 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, supervision 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.

     The Investment Sub-advisory Agreements may be continued with respect to any
of the Funds if approved, after the initial two year term, 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

majority of the relevant Fund's outstanding voting securities.
    
 
     Subject to the Exemption, the Investment Sub-advisory Agreements may be

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 "About the Series Company's Management."
    
 
   
     Virtually all of the over-the-counter transactions by the actively managed
portion of the Small Cap Value Fund, the High Yield Bond Fund, the Strategic
Bond Fund, the Domestic Bond Fund and the Mid Cap Growth Fund, are principal
transactions with issuers and dealers at net prices which entail no brokerage
commissions. The International Value 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 Balanced 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.
 
                                       42
<PAGE>   115
 
     In purchasing and selling each Fund's portfolio securities, it is the
policy of VALIC and the Sub-advisers (collectively, the "Advisers") to seek the
best execution at the most favorable price through responsible broker-dealers
and, in the case of agency transactions, at competitive commission rates. When
selecting brokers or dealers, and in negotiating prices and commissions, the
Advisers consider such factors as: the broker or dealer's reliability; the
quality of the broker or dealer's execution services on a continuing basis; the
rate of the commission; the size and difficulty of the order and the timeliness
of execution; the reliability, integrity, financial condition, general
execution, and operational capabilities of that firm and competing
broker-dealers. In over-the-counter transactions, the Advisers place orders
directly with the principal market-maker unless they believe the Series Company
can obtain a better price (or receive better execution of orders) from a broker
on an agency basis. In transactions executed on securities or commodities
exchanges, the Advisers seek the best overall price and execution at the most
favorable commission rate (except when higher brokerage commissions are paid to
obtain brokerage and research services, as explained below). When the Advisers
believe that more than one firm meets these criteria the Advisers may prefer
brokers who provide the Advisers or the Series Company with brokerage and
research services, described below.
 
     The Advisers may cause a Fund to pay a broker-dealer a commission (for
executing a securities transaction) that is greater than the commission another
broker-dealer would have received for executing the same transaction, if the
Advisers determine in good faith that the greater commission paid to the first
broker-dealer is reasonable in relation to the value of brokerage and research
services provided to the Advisers viewed in terms of either that particular
transaction or the overall responsibilities of the Advisers.
 
     The Advisers receive a wide range of research services from broker-dealers,
including: information on securities markets, the economy and individual
companies; statistical information; accounting and tax law interpretations;
technical market action; pricing and appraisal services; and credit analyses.
Research services are received by the Advisers primarily in the form of written
reports, telephone contacts, personal meetings with securities analysts,
corporate and industry spokespersons, and access to various computer-generated
data.
 
     The Advisers have no agreements or understandings with broker-dealers by
which specific amounts of transactions or commissions are directed to specific
broker-dealers.
 
     The Advisers evaluate whether such research services provide lawful and
appropriate assistance to them in the performance of their investment
decision-making responsibilities, for the Series Company. The Advisers will not
cause the Series Company to pay higher commissions without first determining, in
good faith, that the cost is reasonable considering the brokerage and research
services provided, with respect to either the particular transaction or the
Advisers' overall responsibilities with respect to accounts for which they
exercise investment discretion. The Advisers receive research services at no
cost and cannot assign any specific monetary value to them; nevertheless, the
Advisers believe these supplemental investment research services are essential
to the Advisers' ability to provide high quality portfolio management to the
Funds. Research services furnished by broker-dealers through whom a Fund effects
securities transactions may be used by the Advisers in servicing all of the
Funds, and the Advisers may not use all such services in managing the Funds.
 
     The amount of brokerage commissions paid, the quality of execution, the
nature and quality of research services provided, and the amount of commissions
paid to firms providing research services are reviewed quarterly by the Series
Company's Board of Trustees.
 
     Occasions may arise when one or more of the Funds or other accounts that
may be considered affiliated persons of the Funds under the 1940 Act 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 securi-
                                       43

ties available to the Funds. However, the Funds may, alternatively, benefit from
lower broker's commissions and/or correspondingly lower costs for brokerage and
research services by engaging in such combined transactions. In the Advisers'
opinion, the results of this procedure will, on the whole, be in the best
interest of each Fund.
 
               OFFERING, PURCHASE, AND REDEMPTION OF FUND SHARES
 
   
     Pursuant to a distribution and service agreement, The Variable Annuity
Marketing Company ("VAMCO") acts without remuneration as the Series Company's
agent in the distribution of Fund Shares to registered and unregistered separate
accounts of VALIC and its affiliates. VAMCO's address is the same as that of
VALIC.
    
 
   
     The distribution and service agreement between VAMCO and the Series Company
provides that it shall continue in force from year to year, after the initial
two year term, 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 and service agreement may be terminated at any time,
without penalty, by a vote of the Board of Trustees of the Series Company or by
a vote of a majority of the outstanding voting securities of the Series Company,
or by VAMCO, on sixty days' written notice to the other party. The distribution
and service agreement also automatically terminates in the event of an
assignment.
    
 
   
     Pursuant to the distribution and service agreement VAMCO pays promotional
and advertising expenses and the cost of printing prospectuses used to offer and
sell shares of the Series Company (after typesetting and printing the copies
required for regulatory filings by the Series Company). Promotional and
advertising expenses include any expense related to distribution of shares of
the Funds or attributable to any activity primarily intended to result in the
sale of shares, including, for example, the preparation, printing, and
distribution of advertising and sales literature (including reports to
shareholders used as sales literature). VALIC reimburses VAMCO for these
expenses. Thus all such expenses incurred by VAMCO are passed directly on to
VALIC, its parent. The Series Company pays all expenses related to the
registration of Fund shares under federal and state laws, including registration
and filing fees, the cost of preparing the prospectus for such purpose, and
related expenses of outside legal and auditing firms.
    
 
     As explained in the prospectus for the Contracts, payments of surrender
values, as well as lump sum payments available under the annuity options of the
Contracts, may be suspended or postponed at any time when redemption of shares
is suspended. Normally, the Series Company redeems Fund shares within seven days
of receipt of request therefor, but may postpone redemptions beyond seven days
when: (1) the New York Stock Exchange is closed for other than weekends and
customary holidays, or trading on the New York Stock Exchange becomes
restricted; (2) an emergency exists making disposal or valuation of a Fund's
assets not reasonably practicable; or (3) the SEC has so permitted by order for
the protection of the Series Company's shareholders.
 
     The Series Company normally redeems Fund shares for cash. Although the
Series Company, with respect to each Fund, may make full or partial payment by
assigning to investors, Series Company portfolio securities at their value used
in determining the redemption price (i.e. by redemption-in-kind), the Series
Company, pursuant to Rule 18f-1 under the 1940 Act, has filed a notification of
election on Form 18f-1. Pursuant to this election, the Series Company has
committed 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.

<PAGE>   117
 
                        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 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 the
Custodian.
    
 
     Short-term debt securities for which market quotations are readily
available are valued at the last reported bid price, except for those with a
remaining maturity of 60 days or less which are valued by the amortized cost
method (unless, due to special circumstances, the use of such a method with
respect to any security would result in a valuation which does not approximate
fair market value).
 
     Convertible bonds are valued at prices obtained from one or more of the
major dealers in such bonds. Where there is a discrepancy between dealers or
when no quotes are readily available, values may be adjusted based on a
combination of yields and premium spreads to the underlying common stock.
 
     Portfolio securities that are primarily traded on foreign securities
exchanges are generally valued at the last sale price on the exchange where such
security is primarily traded. All foreign securities traded on the
over-the-counter market are valued at the last sale quote, if market quotations
are available, or the last closing bid price, if there is no active trading in a
particular security for a given day. Where market quotations are not readily
available for such foreign over-the-counter securities, then such securities
will be valued in good faith by a method that the Series Company's Board of
Trustees, or its delegates, believes accurately reflects fair value. Quotations
of foreign securities in foreign currencies are converted, at current exchange
rates, to their U.S. dollar equivalents in order to determine their current
value. In addition, because of the need to value foreign securities (other than
ADRs) as of the close of trading on various exchanges and over-the-counter
markets throughout the world, the calculation of the net asset value of Funds
investing in such foreign securities may not take place contemporaneously with
the valuation of such foreign securities in those Funds' portfolios.
 
     Options purchased by the Funds (including options on financial futures
contracts, stock indices, foreign currencies, and securities) listed on national
securities exchanges are valued on the exchange where such security is primarily
traded.
 
     Over-the-counter options purchased or sold by the Funds are valued based
upon prices provided by market-makers in such securities or dealers in such
currencies.
 
     Exchange-traded financial futures contracts (including interest rate
futures contracts, stock index futures contracts, and currency futures
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 portfo-
                                       45
<PAGE>   118
 
lio securities. The Series Company's Board of Trustees has established
procedures reasonably designed, taking into account current market conditions
and Money Market Fund's investment objective, to stabilize the net asset value
per share for purposes of sales and redemptions at $1.00. These procedures
include review by the Board, at such intervals as it deems appropriate, to
determine the extent, if any, to which the net asset value per share calculated
by using available market quotations deviates from $1.00 per share. In the event
such deviation should exceed one half of one percent, the Board will promptly
consider initiating corrective action. If the Board believes that the extent of
any deviation from a $1.00 amortized cost price per share may result in material
dilution or other unfair results to new or existing shareholders, it will take
such steps as it considers appropriate to eliminate or reduce these consequences
to the extent reasonably practicable. Such steps may include: selling portfolio
securities prior to maturity; shortening the average maturity of the portfolio;
withholding or reducing dividends; or utilizing a net asset value per share
determined from available market quotations. Even if these steps were taken, the
Money Market Fund's net asset value might still decline.
 
                 CALCULATION OF YIELD FOR THE MONEY MARKET FUND
 
     The yield of the Money Market Fund is its net income expressed as a
percentage of assets on an annualized basis for a seven day period. Rule 482
under the 1933 Act requires that a yield quotation set forth in an advertisement
for a money market fund be computed by a standardized method based on an
historical seven calendar day period. The current yield is computed by
determining the net change (exclusive of realized gains and losses from the sale
of securities and unrealized appreciation and depreciation) in the value of a
hypothetical pre-existing account having a balance of one share at the beginning
of the period, and then dividing the net change in account value by the value of
the account at the beginning of the base period to obtain the base period
return. The base period return is then multiplied by (365/7) to annualize the
yield figure. The determination of net change in account value reflects the
value of additional shares purchased with dividends from the original share,
dividends declared on both the original share and such additional shares, and
any fees that are charged to all shareholder accounts, in proportion to the
length of the base period and the Money Market Fund's average account size. The
Money Market Fund may also calculate its compound effective yield by compounding
the unannualized base period return (calculated as described above) by adding
one to the base period return, raising the sum to a power equal to 365 divided
by 7, and subtracting one.
 
     The yield quoted by the Money Market Fund at any time represents the amount
being earned on a current basis for the indicated period and is a function of
the types of instruments in the Money Market Fund's portfolio, their quality and
length of maturity, and the Money Market Fund's operating expenses. The length
of maturity for the portfolio is the average dollar weighted maturity of the
portfolio. In other words, the portfolio has an average maturity for all of its
issues, stated in numbers of days and weighted according to the relative value
of each investment.
 
     The yield fluctuates daily as the income earned on the investments of the
Money Market Fund fluctuates. Accordingly, neither the Series Company nor VALIC
can assure the yield quoted on any given occasion will remain constant for any
period of time. For example, the Money Market Fund's 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 diversifies its holdings so that, at the close of each quarter
of its taxable year, (i) at least 50% of the market value of such Fund's total
(gross) assets is comprised of cash, cash items, U.S. Government securities,
securities of other regulated investment companies and other securities limited
in respect of any one issuer to an amount not greater in value than 5% of the
value of such Fund's total assets and to not more than 10% of the outstanding
voting securities of such issuer, and (ii) not more than 25% of the value of its
total (gross) assets is invested in the securities of any one issuer (other than
U.S. Government securities and securities of other regulated investment
companies) or two or more issuers controlled by the Fund and engaged in the
same, similar or related trades or businesses. For purposes of the 90% gross
income test, income that a Fund earns from equity interests in certain entities
that are not treated as corporations (e.g., partnerships or trusts) for U.S. tax
purposes will generally have the same character for such Fund as in the hands of
such an entity; consequently, a Fund may be required to limit its equity
investments in such entities that earn fee income, rental income, or other
nonqualifying income. In addition, future Treasury regulations could provide
that qualifying income under the 90% gross income test will not include gains
from foreign currency transactions that are not directly related to a Fund's
principal business of investing in stock or securities or options and futures
with respect to stock or securities. Using foreign currency positions or
entering into foreign currency options, futures and forward or swap contracts
for purposes other than hedging currency risk with respect to securities in a
Fund's portfolio or anticipated to be acquired may not qualify as
"directly-related" under these tests.
    
 
     If a Fund complies with such provisions, then in any taxable year in which
such Fund distributes, in compliance with the Code's timing and other
requirements, at least 90% of its "investment company taxable income" (which
includes dividends, taxable interest, taxable accrued original issue discount
and market discount income, income from securities lending, any net short-term
capital gain in excess of net long-term capital loss, certain net realized
foreign exchange gains and any other taxable income other than "net capital
gain," as defined below, and is reduced by deductible expenses), and at least
90% of the excess of its gross tax-exempt interest income (if any) over certain
disallowed 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
 
                                       47
<PAGE>   120
 
the credit exceeds such liabilities. For U.S. federal income tax purposes, the
tax basis of shares owned by a shareholder of the Fund will be increased by an
amount equal under current law to 65% of the amount of undistributed net capital
gain included in the shareholder's gross income. Each Fund intends to distribute
for each taxable year to its shareholders all or substantially all of its
investment company taxable income, net capital gain and any net tax-exempt
interest. Exchange control or other foreign laws, regulations or practices may
restrict repatriation of investment income, capital or the proceeds of
securities sales by foreign investors and may therefore make it more difficult
for certain Funds to satisfy the distribution requirements described above, as
well as the excise tax distribution requirements described below. However, each
Fund generally expects to be able to obtain sufficient cash to satisfy such
requirements from new investors, the sale of securities or other sources. If for
any taxable year a Fund does not qualify as a regulated investment company, it
will be taxable on all of its investment company taxable income and net capital
gain at corporate rates, and its distributions to shareholders will be taxable
as ordinary dividends to the extent of its current and accumulated earnings and
profits.
 
     In order to avoid a 4% federal excise tax, each Fund must distribute (or be
deemed to have distributed) by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
capital gains over its capital losses (generally computed on the basis of the
one-year period ending on October 31 of such year), and all taxable ordinary
income and the excess of capital gains over capital losses for the previous year
that were not distributed for such year and on which the Fund paid no federal
income tax. For federal income tax purposes, dividends declared by a Fund in
October, November or December to shareholders of record on a specified date in
such a month and paid during January of the following year are taxable to such
shareholders as if received on December 31 of the year declared. The Funds
anticipate that they will generally make timely distributions of income and
capital gains in compliance with these requirements so that they will generally
not be required to pay the excise tax. For federal income tax purposes, each
Fund is permitted to carry forward a net capital loss in any year to offset its
own capital gains, if any, during the eight years following the year of the
loss.
 
     Gains and losses on the sale, lapse, or other termination of options and
futures contracts, options thereon and certain forward contracts (except certain
foreign currency options, forward contracts and futures contracts) will
generally be treated as capital gains and losses. Certain of the futures
contracts, forward contracts and options held by a Fund will be required to be
"marked-to-market" for federal income tax purposes, that is, treated as having
been sold at their fair market value on the last day of the Fund's taxable year.
These provisions may require a Fund to recognize income or gains without a
concurrent receipt of cash. Any gain or loss recognized on actual or deemed
sales of these futures contracts, forward contracts, or options will (except for
certain foreign currency options, forward contracts, and futures contracts) be
treated as 60% long-term capital gain or loss and 40% short-term capital gain or
loss. As a result of certain hedging transactions entered into by a Fund, the
Fund may be required to defer the recognition of losses on futures contracts,
forward contracts, and options or underlying securities or foreign currencies to
the extent of any unrecognized gains on related positions held by such Fund and
the characterization of gains or losses as long-term or short-term may be
changed. The tax provisions described above applicable to options, futures and
forward contracts may affect the amount, timing and character of a Fund's
distributions to shareholders. Application of certain requirements for
qualification as a regulated investment company and/or these tax rules to
certain investment practices, such as dollar rolls, or certain 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
 
                                       48
<PAGE>   121
 
that would alter this treatment. If a net foreign exchange loss treated as
ordinary loss under Section 988 of the Code were to exceed a Fund's investment
company taxable income (computed without regard to such loss) for a taxable
year, the resulting loss would not be deductible by the Fund or its shareholders
in future years. Net loss, if any, from certain foreign currency transactions or
instruments would exceed net investment income otherwise calculated for
accounting purposes with the result being either no dividends being paid or a
portion of a Fund's dividends being treated as a return of capital for tax
purposes, nontaxable to the extent of a shareholder's tax basis in his shares
and, once such basis is exhausted, generally giving rise to capital gains.
 
     A Fund's investment in zero coupon securities, deferred interest
securities, certain structured securities or other securities bearing original
issue discount or, if a Fund elects to include market discount in income
currently, market discount, as well as any "mark-to-market" gain from certain
options, futures or forward contracts, as described above, will generally cause
it to realize income or gain prior to the receipt of cash payments with respect
to these securities or contracts. In order to obtain cash to enable it to
distribute this income or gain, maintain its qualification as a regulated
investment company and avoid federal income or excise taxes, the Fund may be
required to liquidate portfolio securities that it might otherwise have
continued to hold.
 
     Certain Funds may be subject to foreign taxes on income (possibly
including, in some cases, capital gains) from foreign securities. Tax
conventions between certain countries and the U.S. may reduce or eliminate such
taxes in some cases. If, as may occur for certain Funds, more than 50% of a
Fund's total assets at the close of any taxable year consists of stock or
securities of foreign corporations, the Fund may file an election with the
Internal Revenue Service pursuant to which shareholders of the Fund would be
required to (i) include in ordinary gross income (in addition to taxable
dividends actually received) their pro rata shares of foreign income taxes paid
by the Fund that are treated as income taxes under U.S. tax regulations (which
excludes, for example, stamp taxes, securities transaction taxes, and similar
taxes) even though not actually received by such shareholders, and (ii) treat
such respective pro rata portions as foreign income taxes paid by them.
 
     If a Fund makes this election, its respective shareholders may then deduct
such pro rata portions of qualified foreign taxes in computing their taxable
incomes, or, alternatively, use them as foreign tax credits, subject to
applicable limitations, against their U.S. federal income taxes. Shareholders
who do not itemize deductions for federal income tax purposes will not, however,
be able to deduct their pro rata portion of foreign taxes paid by a Fund,
although such shareholders will be required to include their shares of such
taxes in gross income if the election is made.
 
     If a shareholder chooses to take credit for the foreign taxes deemed paid
by such shareholder as a result of any such election by a Fund, the amount of
the credit that may be claimed in any year may not exceed the same proportion of
the U.S. tax against which such credit is taken which the shareholder's taxable
income from foreign sources (but not in excess of the shareholder's entire
taxable income) bears to his entire taxable income. For this purpose,
distributions from long-term and short-term capital gains or foreign currency
gains by a Fund will generally not be treated as income from foreign sources.
This foreign tax credit limitation may also be applied separately to certain
specific categories of foreign-source income and the related foreign taxes. As a
result of these rules, which have different effects depending upon each
shareholder's particular tax situation, certain shareholders of a Fund which has
made this election may not be able to claim a credit for the full amount of
their 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.
 
                                       49
<PAGE>   122
 
     If a Fund acquires stock (including, under proposed regulations, an option
to acquired stock such as is inherent in a convertible bond) in certain foreign
corporations that receive at least 75% of their annual gross income from passive
sources (such as interest, dividends, rents, royalties or capital gain) or hold
at least 50% of their assets in investments producing such passive income
("passive foreign investment companies"), the Fund could be subject to federal
income tax and additional interest charges on "excess distributions" received
from such companies or gain from the sale of stock in such companies, even if
all income or gain actually received by the Fund is timely distributed to its
shareholders. The Fund would not be able to pass through to its shareholders any
credit or deduction for such a tax. In some cases, elections may be available
that would ameliorate these adverse tax consequences, but such elections would
require the Fund to include certain amounts as income or gain (subject to the
distribution requirements described above) without a concurrent receipt of cash.
Each Fund may limit and/or manage its holdings in passive foreign investment
companies to minimize its tax liability or maximize its return from these
investments.
 
     Investments in lower-rated securities may present special tax issues for a
Fund to the extent actual or anticipated defaults may be more likely with
respect to such securities. Tax rules are not entirely clear about issues such
as when a Fund may cease to accrue interest, original issue discount, or market
discount; when and to what extent deductions may be taken for bad debts or
worthless securities; how payments received on obligations in default should be
allocated between principal and income; and whether exchanges of debt
obligations in a workout context are taxable. These and other issues will be
addressed by a Fund, in the event it invests in such securities, in order to
seek to eliminate or minimize any adverse tax consequences.
 
SECTION 817(h) OF THE CODE
 
     Each of the Funds intends to comply with Section 817(h) of Code and the
regulations issued thereunder. Section 817(h) of the Code and Treasury
Department regulations thereunder impose certain diversification requirements on
variable annuity contracts based upon segregated asset accounts. These
requirements are in addition to the diversification requirements of Subchapter M
and the 1940 Act and may affect the securities in which a Fund may invest.
Failure to meet the requirements of Section 817(h) could result in immediate
taxation of the Contract owner to the extent of appreciation on investment under
the Contract.
 
   
     The Section 817(h) diversification requirements do not apply to pension
plan contracts. "Pension plan contracts" for these purposes generally means
annuity contracts issued with respect to plans qualified under Section 401(a) or
403(a) of the Code, Section 403(b) annuities, Individual Retirement Accounts,
Individual Retirement Annuities and annuities issued with respect to Section 457
plans.
    
 
     The Secretary of the Treasury may, in the future, issue additional
regulations that will prescribe the circumstances in which a Contract Owner's
control of the investments of the separate accounts investing in the Series
Company may cause the Contract Owner, rather than VALIC, to be treated as the
owner of the assets of that separate account.
 
   
     In order to comply with the requirements of Section 817(h) and the
regulations thereunder, the Series Company may find it necessary to take action
to ensure that a Contract funded by the Series Company continues to qualify as
such under federal tax laws. The Series Company, for example, may be required to
alter the investment objectives of a Fund or Funds, or substitute the shares of
one fund for those of another. No such change of investment objectives or
substitution of securities will take place without notice to the shareholders of
the affected Fund, and the approval of a majority of such shareholders (as
defined in the 1940 Act) and without prior approval of the Securities and
Exchange Commission, to the extent legally required.
    
 
     It is not feasible to comment on all of the federal income tax consequences
concerning the Funds. Each owner of a Contract funded by the Series Company
should consult a qualified tax adviser for more complete information. The reader
should refer to the appropriate prospectus related to his or her Contracts for a
more complete description of the taxation of the separate account and of the
owner of the particular Contract.

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 the Custodian 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 the Custodian to release to its general custodial
account any assets to which a Fund is entitled under the terms of such
agreement, and (4) that the assets in the segregated account shall otherwise be
used only to satisfy the Series Company's obligations to the FCM or broker under
the terms of such agreement.
    
 
     If on any day a Fund experiences net realized or unrealized gains with
respect to financial futures contracts or covered options on stock indices held
through a given FCM or broker, it is entitled immediately to receive from the
FCM or broker, and usually will receive by the next business day, the net amount
of such gains. Thereupon, such assets will
 
                                       51
<PAGE>   124
 
   
be deposited in its general or segregated account with the Custodian, as
appropriate.

                         Report of Independent Auditors

To the Shareholder and Board of Trustees of
   American General Series Portfolio Company 3

We have audited the accompanying statement of net assets of International Growth
Fund, Large Cap Growth Fund, Mid Cap Growth Fund, Small Cap Growth Fund,
International Value Fund, Large Cap Value Fund, Mid Cap Value Fund, Small Cap
Value Fund, Socially Responsible Fund, Balanced Fund, High Yield Bond Fund,
Strategic Bond Fund, Domestic Bond Fund, Core Bond Fund, Money Market Fund,
Growth Lifestyle Fund, Moderate Growth Lifestyle Fund, and Conservative Growth
Lifestyle Fund (such "Funds" comprising the American General Series Portfolio
Company 3) as of August 26, 1998. This financial statement is the responsibility
of the Company's management. Our responsibility is to express an opinion on this
financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the financial position of each of the respective Funds
comprising the American General Series Portfolio Company 3 at August 26, 1998, 
in conformity with generally accepted accounting principles.

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 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.

                          INVESTMENT ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as the "ADVISER," and
AMERICAN GENERAL SERIES PORTFOLIO COMPANY 3, 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
         registered under the Investment Advisers Act of 1940.

                  (b) The FUND is an investment company organized under the laws
         of Delaware as a business trust, as a series type of investment company

         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

         General Domestic 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, American General Conservative Growth Lifestyle Fund,
         American General Core Bond Fund, American General Strategic Bond Fund,
         and American General High Yield Bond 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").

         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 the 1940 Act, all applicable
laws and regulations thereunder, all other applicable federal and state laws and
regulations, including 817(b) of the Internal Revenue Code of 1986, as amended
(the "Code"), 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.

                  (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


<PAGE>   2



         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. 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) brokerage commissions and other expenses of purchasing
and selling portfolio investments; (iii) compensation of its 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 related to issuance of 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; and (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.

         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


                                        2

<PAGE>   3



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 1940 Act, 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
adopted and approved in conformity with applicable laws and regulations, and (d)
such sub-advisory agreement may be terminated at any time, on not more than 60
days' written notice, by the ADVISER on notice to the sub-adviser and the FUND,
by the sub-adviser on notice to the ADVISER and the FUND, and by the FUND's
Board of Trustees or by a majority vote of the Covered Fund's outstanding voting
securities on notice to the sub-adviser and the ADVISER.

4.       DURATION OF AGREEMENT

         This Agreement shall become effective as to the Covered Funds set forth
on Schedule A on the date hereof and as to any other Funds on the date of the
Amendment to Schedule A adding such Fund in accordance with this Agreement.
Unless sooner terminated as provided herein, this Agreement shall continue in
effect for two years from the effective date. Thereafter this Agreement shall
continue in effect, but with respect to any Covered Fund, subject


                                        3

<PAGE>   4



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 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 the 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.

                        INVESTMENT SUB-ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as "VALIC," and JACOBS
ASSET MANAGEMENT, hereinafter referred to as the "SUB-ADVISER."

         VALIC and the SUB-ADVISER recognize the following:

                  (a) VALIC is a life insurance company organized under Chapter
         3 of the Texas Insurance Code and an investment adviser registered
         under the Investment Advisers Act of 1940, as amended ("Advisers Act").

                  (b) VALIC is engaged as the investment adviser of American
         General International Growth Fund pursuant to an Investment Advisory
         Agreement dated August 26, 1998 between VALIC and American General
         Series Portfolio Company 3 ("FUND"), 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 a diversified, open-end,
         management investment company under the Investment Company Act of 1940,
         as amended ("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
         ("Funds"): American General International Value Fund, American General
         International Growth Fund, American General Large Cap Value Fund,
         American General Large Cap Growth Fund, American General Mid Cap Value
         Fund, American General Mid Cap Growth Fund, American General Small Cap
         Value Fund, American General Small Cap Growth Fund, American General
         Socially Responsible Fund, American General Money Market Fund, American
         General Domestic Bond Fund, American General Balanced Fund, American
         General Conservative Growth Lifestyle Fund, American General Moderate
         Growth Lifestyle Fund, American General Growth Lifestyle Fund, American
         General Core Bond Fund, American General Strategic Bond Fund, and
         American General High Yield Bond Fund. In accordance with the FUND's
         Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A, and any other
         Funds as may be added or deleted by amendment to the attached Schedule
         A ("Covered Funds").

                  (d) The SUB-ADVISER is engaged principally in the business of
         rendering investment advisory services and is registered as an
         investment adviser under the Advisers Act.

                  (e) VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign to
         the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with the 1940 Act, all
applicable laws and regulations thereunder, all other applicable federal and
state laws and regulations, including section 817(h) of the Internal Revenue
Code of 1986, as amended (the "Code"), the FUND's Declaration, Bylaws,
registration statements, prospectus and stated investment objectives, policies
and restrictions and any applicable procedures adopted by the FUND's Board of
Trustees shall:



                                        1

<PAGE>   2



                  (a) manage the investment and reinvestment of the assets,
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon) for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB-ADVISER, subject to applicable law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution. Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 SUB-ADVISER. The
SUB-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 SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of services
under this Agreement. The SUB-ADVISER will make available to VALIC and the FUND
promptly upon their request all of the Covered Funds' investment records and
ledgers to assist VALIC and the FUND in compliance with respect to each Covered
Fund's securities transactions as required by the 1940 Act and the Advisers Act,
as well as other applicable laws. The SUB-ADVISER will furnish the FUND's Board
of Trustees such periodic and special reports as VALIC and the FUND's Board of
Trustees may reasonably request. The SUB-ADVISER will furnish to regulatory
authorities any information or reports in connection with such services which
may be requested in order to ascertain whether the operations of the Covered
Funds are being conducted in a manner consistent with applicable laws and
regulations. The SUB-ADVISER will not disclose or use any records or information
obtained pursuant to this Agreement in any manner whatsoever except as expressly
authorized in this Agreement, and will keep confidential any information
obtained pursuant to this service relationship, and disclose such information
only if VALIC or the Board of Trustees of the FUND has authorized such
disclosure, or if such information is or hereafter becomes ascertainable from
public or published information or trade sources, or if such disclosure is
expressly required or requested by applicable federal or state authorities.

         Should VALIC at any time make any definite determination as to
investment policy and notify the SUB- ADVISER of such determination, the
SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination has
been revoked.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND. The money and investments will be held by the Custodian of the FUND. The
SUB-ADVISER will arrange for the transmission to the Custodian for the FUND, on
a daily basis, such confirmation, trade tickets and other documents as may be
necessary to enable it to perform its administrative responsibilities with
respect to the Covered Funds.

         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.



                                        2

<PAGE>   3



         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in furtherance
of the SUB-ADVISER's duties and responsibilities as set forth in this Agreement.

         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities hereunder
and VALIC shall pay, or arrange for others to pay, all VALIC's expenses, except
that VALIC shall in all events pay the compensation described in Section 2 of
this Agreement.

2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB-ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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. VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than thirty
(30) days following the end of the month.

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

         The payment of advisory fees related to the services of the SUB-ADVISER
under this Agreement shall be the sole responsibility of VALIC and shall not be
the responsibility of the FUND.

3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered Funds.

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

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER.

         This Agreement shall become effective as to the Fund(s) set forth on

Unless sooner terminated as provided herein, this Agreement shall continue in
effect for two years from its effective 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

         This Agreement shall automatically terminate in the event of its
assignment, as that term is defined in the 1940 Act, or in the event of the

Covered Fund at any time, without the payment of any penalty, by vote of the

outstanding voting securities on at least 60 days' prior written notice to the
SUB-ADVISER. This Agreement may also be terminated by VALIC: (i) on at least 60

6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act. The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property. The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder. The SUB-ADVISER further agrees to
preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records
required to be maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to
furnish the SUB-ADVISER copies of any amendments or supplements thereto before
or at the time the amendments or supplements become effective.

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND in writing
signed or sent by any of the persons whose names, addresses and specimen
signatures will be provided by VALIC from time to time. The SUB-ADVISER shall
not be liable for so acting in good faith upon such instructions, confirmation
or authority, notwithstanding that it shall subsequently be shown that the same
was not given or signed or sent by an authorized person.

         VALIC agrees to furnish the SUB-ADVISER at its principal office prior
to use thereof, copies of all prospectuses, proxy statements, reports to
shareholders, sales literature, or other material prepared for distribution to
interest holders of the FUND or the public that refer in any way to the
SUB-ADVISER, and not to use such material if the SUB-ADVISER reasonably objects
in writing within ten (10) business days (or such other time as may be mutually
agreed) after receipt thereof. In the event of termination of this agreement,
VALIC will continue to furnish to the SUB-ADVISER copies of any of the
above-mentioned materials that refer in any way to the SUB-ADVISER. VALIC shall
furnish or otherwise make available to the SUB-ADVISER such other information
relating to the business affairs of VALIC and the FUND as the SUB-ADVISER at any
time, or from time to time, may reasonably request in order to discharge
obligations hereunder.

         VALIC agrees to indemnify the SUB-ADVISER for losses and claims which
arise (i) as a result of a failure by VALIC to provide the services or furnish
materials required under the terms of this Investment Sub-Advisory Agreement, or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to the FUND, except insofar as any
such statement or omission was made in reliance on information provided by the
SUB-ADVISER or its affiliates.

         The SUB-ADVISER agrees to indemnify VALIC for losses and claims which
arise (i) as a result of a failure by SUB-ADVISER to provide the services or
furnish the materials required under the terms of this Investment Sub- Advisory
Agreement, including a negligent failure whether unintentional or in good faith
or otherwise, to comply with the diversification requirements specified in
section 817(h), and the qualification standards of Subchapter M of the Code, as
amended, and the regulations thereunder, (other than a failure which is
subsequently timely corrected by the SUB- ADVISER in accordance with applicable
law and regulations such that no loss is incurred by VALIC or a Covered Fund) or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to


                                        5

<PAGE>   6



the FUND to the extent any such statement or omission was made in reliance on
information provided by the SUB- ADVISER or its affiliates.


7.       APPLICABILITY OF FEDERAL SECURITIES LAWS

         This Agreement shall be interpreted in accordance with the laws of the
State of Texas and applicable federal securities laws and regulations, including
definitions therein and such exemptions as may be granted to VALIC or the
SUB-ADVISER 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.

duplicate on its behalf by its duly authorized officer on the above date.

                        INVESTMENT SUB-ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as "VALIC," and GOLDMAN
SACHS ASSET MANAGEMENT, hereinafter referred to as the "SUB-ADVISER."

         VALIC and the SUB-ADVISER recognize the following:

                  (a) VALIC is a life insurance company organized under Chapter
         3 of the Texas Insurance Code and an investment adviser registered
         under the Investment Advisers Act of 1940, as amended ("Advisers Act").

                  (b) VALIC is engaged as the investment adviser of American
         General Large Cap Growth Fund pursuant to an Investment Advisory
         Agreement dated August 26, 1998 between VALIC and American General
         Series Portfolio Company 3 ("FUND"), 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 a diversified, open-end,
         management investment company under the Investment Company Act of 1940,
         as amended ("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
         ("Funds"): American General International Value Fund, American General
         International Growth Fund, American General Large Cap Value Fund,
         American General Large Cap Growth Fund, American General Mid Cap Value
         Fund, American General Mid Cap Growth Fund, American General Small Cap
         Value Fund, American General Small Cap Growth Fund, American General
         Socially Responsible Fund, American General Money Market Fund, American
         General Domestic Bond Fund, American General Balanced Fund, American
         General Conservative Growth Lifestyle Fund, American General Moderate
         Growth Lifestyle Fund, American General Growth Lifestyle Fund, American
         General Core Bond Fund, American General Strategic Bond Fund, and
         American General High Yield Bond Fund. In accordance with the FUND's
         Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A, and any other
         Funds as may be added or deleted by amendment to the attached Schedule
         A ("Covered Funds").

                  (d) The SUB-ADVISER is engaged principally in the business of
         rendering investment advisory services and is registered as an
         investment adviser under the Advisers Act.

                  (e) VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign to
         the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with the 1940 Act, all
applicable laws and regulations thereunder, all other applicable federal and
state laws and regulations, including the diversification requirements pursuant
to section 817(h) and Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"), the FUND's Declaration, Bylaws, registration statements,
prospectus and stated investment objectives, policies and restrictions and any
applicable procedures (which procedures to the extent they govern transactions
involving affiliates, will identify any affiliate of VALIC or the Fund)


                                        1

<PAGE>   2



adopted by the FUND's Board of Trustees (provided that (i) the FUND or VALIC has
provided the SUB-ADVISER with copies of all applicable provisions of the
foregoing FUND documents which relate to the investment and management of the
FUND and promptly notifies the SUB-ADVISER of any changes in such FUND documents
and (ii) VALIC informs the SUB-ADVISER of all applicable state insurance laws
relating to the investment and management of the FUND, including restrictions or
limitations on investments in the Fund, and promptly notifies the SUB-ADVISER of
any changes in such laws or restrictions) shall:

                  (a) manage the investment and reinvestment of the assets.
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon) for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB-ADVISER, subject to applicable law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution. Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 SUB-ADVISER. The
SUB-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 SUB-ADVISER will make available to VALIC and the FUND promptly
upon their request all of the Covered Funds' investment records and ledgers to
assist VALIC and the FUND in compliance with respect to each Covered Fund's
securities transactions as required by the 1940 Act and the Advisers Act, as
well as other applicable laws. The SUB-ADVISER will furnish the FUND's Board of
Trustees such periodic and special reports as VALIC and the FUND's Board of
Trustees may reasonably request. The SUB-ADVISER will furnish to regulatory
authorities any information or reports in connection with such services which
may be requested in order to ascertain whether the operations of the Covered
Funds are being conducted in a manner consistent with applicable laws and
regulations. VALIC and the SUB-ADVISER will not disclose or use any records or
information obtained pursuant to this Agreement (excluding investment research
and investment advice) in any manner whatsoever except as expressly authorized
in this Agreement, or in the ordinary course of business of performing the
services described herein and will keep confidential any information obtained
pursuant to this service relationship, and disclose such information only if
VALIC and the SUB-ADVISER or the Board of Trustees of the FUND has authorized
such disclosure, or if such information is or hereafter becomes ascertainable
from public or published information or trade sources, or if such disclosure is
expressly required or requested by applicable federal or state authorities or as
may be required by the legal process or in connection with any litigation
arising out of this Agreement.

         Should VALIC at any time make any definite determination as to
investment policy and notify the SUB- ADVISER of such determination, the
SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination has
been revoked.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND. The money and investments will be held by the Custodian of the FUND. The
SUB-ADVISER will arrange for the transmission to the Custodian for


                                        2

<PAGE>   3



the FUND, on a daily basis, such confirmation, trade tickets and other documents
as may be necessary to enable it to perform its administrative responsibilities
with respect to the Covered Funds.

         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.

         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in furtherance
of the SUB-ADVISER's duties and responsibilities as set forth in this Agreement.

         The SUB-ADVISER may on occasion when the purchase or sale of a security
is deemed to be in the best interest of the FUND as well as any other investment
advisory clients, to the extent permitted by applicable laws and regulations,
but shall not be obligated to aggregate the securities sold or purchased with
those of its other clients where such aggregation is not inconsistent with the
policies set forth in the FUND's registration statement.

         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities hereunder
and VALIC shall pay, or arrange for others to pay, all VALIC's expenses, except
that VALIC shall in all events pay the compensation described in Section 2 of
this Agreement.


2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB-ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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. VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than thirty
(30) days following the end of the month.

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

         The payment of advisory fees related to the services of the SUB-ADVISER
under this Agreement shall be the sole responsibility of VALIC and shall not be
the responsibility of the FUND.


3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered Funds.

         Except as otherwise required by the 1940 Act, any of the shareholders,
directors, officers and employees of VALIC may be a shareholder, director,
officer or employee of, or be otherwise interested in, the SUB-ADVISER, and in
any person controlling, controlled by or under common control with the
SUB-ADVISER; and the SUB-ADVISER,


                                        3

<PAGE>   4



and any person controlling, controlled by or under common control with the
SUB-ADVISER, may have an interest in VALIC.

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER.

         VALIC shall perform quarterly and annual tax compliance tests and
promptly furnish reports of such tests to the SUB-ADVISER after each quarter end
to ensure that the Fund is in compliance with Subchapter M of the Code and
Section 817(h) of the Code. VALIC shall apprise the SUB-ADVISER promptly after
each quarter end of any potential non-compliance with the diversification
requirements in such Code provisions. If so advised, the SUB-ADVISER shall take
prompt action so that the Fund(s) comply with such Code diversification
provisions, as directed by VALIC.

Covered Fund at any time, without the payment of any penalty, by vote of the
FUND's Board of Trustees or by vote of a majority of that Covered Fund's
outstanding voting securities on at least 60 days' prior written notice to the
SUB-ADVISER. This Agreement may also be terminated by VALIC: (i) on at least 60
days' prior written notice to the SUB-ADVISER, without the payment of any
penalty; or (ii) if the SUB-ADVISER becomes unable to discharge its duties and
obligations under this Agreement. The SUB-ADVISER may terminate this Agreement
at any time, or preclude its renewal without the payment of any penalty, on at
least 60 days' prior written notice to VALIC.


6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act. The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property. The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder. The SUB-ADVISER further agrees to
preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records
required to be maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to
furnish SUB-ADVISER copies of any amendments or supplements thereto before or at
the time the amendments or supplements become effective. Until VALIC delivers
any amendments or supplements to the SUB-ADVISER, the SUB- ADVISER shall be
fully protected in relying on the documents previously furnished to it.

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND by any of the
persons whose names, addresses and specimen signatures will be provided by VALIC
from time to time. The SUB-ADVISER shall not be liable for so acting in good
faith upon such instructions, confirmation or authority, notwithstanding that it
shall subsequently be shown that the same was not given or signed or sent by an
authorized person.

         VALIC agrees to furnish the SUB-ADVISER at its principal office prior
to use thereof, copies of all prospectuses, proxy statements, reports to
shareholders, sales literature, or other material prepared for distribution to
interest holders of the FUND or the public that refer in any way to the
SUB-ADVISER, and not to use such material if the SUB-ADVISER reasonably objects
in writing within ten (10) business days (or such other time as may be mutually
agreed) after receipt thereof. It is understood that the name "Goldman, Sachs &
Co." or "Goldman Sachs" or


                                        5

<PAGE>   6



any derivative thereof, any trade name, trade device, service mark, symbol or
logo associated with the names are the valuable property of the SUB-ADVISER and
that VALIC has the right to use such name (or simulation or logo), in offering
materials of the Fund with the prior written approval of the SUB-ADVISER and for
so long as the SUB- ADVISER is a SUB-ADVISER to the Fund. Upon termination of
this Agreement between the Fund, VALIC and the SUB-ADVISER, the Fund and VALIC
shall forthwith cease to use such name (or simulation or logo). In the event of
termination of this agreement, VALIC will continue to furnish to the SUB-ADVISER
copies of any of the above-mentioned materials that refer in any way to the
SUB-ADVISER. VALIC shall furnish or otherwise make available to the SUB-ADVISER
such other information relating to the business affairs of VALIC and the FUND as
the SUB- ADVISER at any time, or from time to time, may reasonably request in
order to discharge obligations hereunder.

         VALIC agrees to indemnify the SUB-ADVISER for losses and claims which
arise (i) as a result of a failure by VALIC to provide the services or furnish
materials required under the terms of this Investment Sub-Advisory Agreement, or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to the FUND, except insofar as any
such statement or omission was made in reliance on information provided by the
SUB-ADVISER or its affiliates.

         The SUB-ADVISER agrees to indemnify VALIC for losses and claims which
arise (i) as a result of a failure by the SUB-ADVISER to provide the services or
furnish the materials required under the terms of this Investment Sub- Advisory
Agreement, including actions which may be based upon any willful malfeasance,
bad faith, or gross negligence of or by reckless disregard of, the SUB-ADVISER's
obligations and/or duties under this Agreement by the SUB-ADVISER or (ii) as the
result of any untrue statement of a material fact or any omission to state a
material fact required to be stated or necessary to make the statements, in
light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to the FUND to the extent any such
statement or omission was made in reliance on information provided by the
SUB-ADVISER or its affiliates.


7.       APPLICABILITY OF FEDERAL SECURITIES LAWS

         This Agreement shall be interpreted in accordance with the laws of the
State of Texas and applicable federal securities laws and regulations, including
definitions therein and such exemptions as may be granted to VALIC or the
SUB-ADVISER 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.

                        INVESTMENT SUB-ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as "VALIC," and BROWN
CAPITAL MANAGEMENT, INC., hereinafter referred to as the "SUB-ADVISER."

         VALIC and the SUB-ADVISER recognize the following:

                  (a) VALIC is a life insurance company organized under Chapter
         3 of the Texas Insurance Code and an investment adviser registered
         under the Investment Advisers Act of 1940, as amended ("Advisers Act").

                  (b) VALIC is engaged as the investment adviser of American
         General Mid Cap Growth Fund pursuant to an Investment Advisory
         Agreement dated August 26, 1998 between VALIC and American General
         Series Portfolio Company 3 ("FUND"), 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 a diversified, open-end,
         management investment company under the Investment Company Act of 1940,
         as amended ("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
         ("Funds"): American General International Value Fund, American General
         International Growth Fund, American General Large Cap Value Fund,
         American General Large Cap Growth Fund, American General Mid Cap Value
         Fund, American General Mid Cap Growth Fund, American General Small Cap
         Value Fund, American General Small Cap Growth Fund, American General
         Socially Responsible Fund, American General Money Market Fund, American
         General Domestic Bond Fund, American General Balanced Fund, American
         General Conservative Growth Lifestyle Fund, American General Moderate
         Growth Lifestyle Fund, American General Growth Lifestyle Fund, American
         General Core Bond Fund, American General Strategic Bond Fund, and
         American General High Yield Bond Fund. In accordance with the FUND's
         Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A, and any other
         Funds as may be added or deleted by amendment to the attached Schedule
         A ("Covered Funds").

                  (d) The SUB-ADVISER is engaged principally in the business of
         rendering investment advisory services and is registered as an
         investment adviser under the Advisers Act.

                  (e) VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign to
         the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with the 1940 Act, all
applicable laws and regulations thereunder, all other applicable federal and
state laws and regulations, including section 817(h) of the Internal Revenue
Code of 1986, as amended (the "Code"), the FUND's Declaration, Bylaws,
registration statements, prospectus and stated investment objectives, policies
and restrictions and any applicable procedures adopted by the FUND's Board of
Trustees shall:



                                        1

<PAGE>   2



                  (a) manage the investment and reinvestment of the assets,
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon) for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB-ADVISER, subject to applicable law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution. Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 SUB-ADVISER. The
SUB-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 SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of services
under this Agreement. The SUB-ADVISER will make available to VALIC and the FUND
promptly upon their request all of the Covered Funds' investment records and
ledgers to assist VALIC and the FUND in compliance with respect to each Covered
Fund's securities transactions as required by the 1940 Act and the Advisers Act,
as well as other applicable laws. The SUB-ADVISER will furnish the FUND's Board
of Trustees such periodic and special reports as VALIC and the FUND's Board of
Trustees may reasonably request. The SUB-ADVISER will furnish to regulatory
authorities any information or reports in connection with such services which
may be requested in order to ascertain whether the operations of the Covered
Funds are being conducted in a manner consistent with applicable laws and
regulations. The SUB-ADVISER will not disclose or use any records or information
obtained pursuant to this Agreement in any manner whatsoever except as expressly
authorized in this Agreement, and will keep confidential any information
obtained pursuant to this service relationship, and disclose such information
only if VALIC or the Board of Trustees of the FUND has authorized such
disclosure, or if such information is or hereafter becomes ascertainable from
public or published information or trade sources, or if such disclosure is
expressly required or requested by applicable federal or state authorities.

         Should VALIC at any time make any definite determination as to
investment policy and notify the SUB- ADVISER of such determination, the
SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination has
been revoked.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND. The money and investments will be held by the Custodian of the FUND. The
SUB-ADVISER will arrange for the transmission to the Custodian for the FUND, on
a daily basis, such confirmation, trade tickets and other documents as may be
necessary to enable it to perform its administrative responsibilities with
respect to the Covered Funds.

         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.



                                        2

<PAGE>   3



         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in furtherance
of the SUB-ADVISER's duties and responsibilities as set forth in this Agreement.

         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities hereunder
and VALIC shall pay, or arrange for others to pay, all VALIC's expenses, except
that VALIC shall in all events pay the compensation described in Section 2 of
this Agreement.

2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB-ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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. VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than thirty
(30) days following the end of the month.

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

         The payment of advisory fees related to the services of the SUB-ADVISER
under this Agreement shall be the sole responsibility of VALIC and shall not be
the responsibility of the FUND.

3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered Funds.

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

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER.

Unless sooner terminated as provided herein, this Agreement shall continue in
effect for two years from its effective date. Thereafter, this Agreement shall
continue in effect, but with respect to any Covered Fund, subject to the

6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act. The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property. The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder. The SUB-ADVISER further agrees to
preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records
required to be maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to
furnish the SUB-ADVISER copies of any amendments or supplements thereto before
or at the time the amendments or supplements become effective.

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND in writing
signed or sent by any of the persons whose names, addresses and specimen
signatures will be provided by VALIC from time to time. The SUB-ADVISER shall
not be liable for so acting in good faith upon such instructions, confirmation
or authority, notwithstanding that it shall subsequently be shown that the same
was not given or signed or sent by an authorized person.

         VALIC agrees to furnish the SUB-ADVISER at its principal office prior
to use thereof, copies of all prospectuses, proxy statements, reports to
shareholders, sales literature, or other material prepared for distribution to
interest holders of the FUND or the public that refer in any way to the
SUB-ADVISER, and not to use such material if the SUB-ADVISER reasonably objects
in writing within ten (10) business days (or such other time as may be mutually
agreed) after receipt thereof. In the event of termination of this agreement,
VALIC will continue to furnish to the SUB-ADVISER copies of any of the
above-mentioned materials that refer in any way to the SUB-ADVISER. VALIC shall
furnish or otherwise make available to the SUB-ADVISER such other information
relating to the business affairs of VALIC and the FUND as the SUB-ADVISER at any
time, or from time to time, may reasonably request in order to discharge
obligations hereunder.

         VALIC agrees to indemnify the SUB-ADVISER for losses and claims which
arise (i) as a result of a failure by VALIC to provide the services or furnish
materials required under the terms of this Investment Sub-Advisory Agreement, or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to the FUND, except insofar as any
such statement or omission was made in reliance on information provided by the
the SUB-ADVISER or its affiliates.

         The SUB-ADVISER agrees to indemnify VALIC for losses and claims which
arise (i) as a result of a failure by SUB-ADVISER to provide the services or
furnish the materials required under the terms of this Investment Sub- Advisory
Agreement, including a negligent failure whether unintentional or in good faith
or otherwise, to comply with the diversification requirements specified in
section 817(h), and the qualification standards of Subchapter M of the Code, as
amended, and the regulations thereunder, (other than a failure which is
subsequently timely corrected by the SUB- ADVISER in accordance with applicable
law and regulations such that no loss is incurred by VALIC or a Covered Fund) or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to


                                        5

the FUND to the extent any such statement or omission was made in reliance on
information provided by the SUB-ADVISER or its affiliates.

                        INVESTMENT SUB-ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as "VALIC," and J. P.
MORGAN INVESTMENT MANAGEMENT INC., hereinafter referred to as the "SUB-ADVISER."

         VALIC and the SUB-ADVISER recognize the following:

                  (a) VALIC is a life insurance company organized under Chapter
         3 of the Texas Insurance Code and an investment adviser registered
         under the Investment Advisers Act of 1940, as amended ("Advisers Act").

                  (b) VALIC is engaged as the investment adviser of American
         General Small Cap Growth Fund pursuant to an Investment Advisory
         Agreement dated August 26, 1998 between VALIC and American General
         Series Portfolio Company 3 ("FUND"), 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 a diversified, open-end,
         management investment company under the Investment Company Act of 1940,
         as amended ("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
         ("Funds"): American General International Value Fund, American General
         International Growth Fund, American General Large Cap Value Fund,
         American General Large Cap Growth Fund, American General Mid Cap Value
         Fund, American General Mid Cap Growth Fund, American General Small Cap
         Value Fund, American General Small Cap Growth Fund, American General
         Socially Responsible Fund, American General Money Market Fund, American
         General Domestic Bond Fund, American General Balanced Fund, American
         General Conservative Growth Lifestyle Fund, American General Moderate
         Growth Lifestyle Fund, American General Growth Lifestyle Fund, American
         General Core Bond Fund, American General Strategic Bond Fund, and
         American General High Yield Bond Fund. In accordance with the FUND's
         Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A, and any other
         Funds as may be added or deleted by amendment to the attached Schedule
         A ("Covered Funds").

                  (d) The SUB-ADVISER is engaged principally in the business of
         rendering investment advisory services and is registered as an
         investment adviser under the Advisers Act.

                  (e) VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign to
         the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with the 1940 Act, all
applicable laws and regulations thereunder, all other applicable federal and
state laws and regulations, including section 817(h) of the Internal Revenue
Code of 1986, as amended (the "Code"), the FUND's Declaration, Bylaws,
registration statements, prospectus and stated investment objectives, policies
and restrictions and any applicable procedures adopted by the FUND's Board of
Trustees shall:



                                        1

<PAGE>   2
                  (a) manage the investment and reinvestment of the assets,
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon) for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB-ADVISER, subject to applicable law.

         In selecting brokers or dealers to execute transactions on behalf of
the Covered Funds, the SUB-ADVISER will seek the best overall terms available.
In assessing the best overall terms available for any transaction, the SUB-
ADVISER will consider factors it deems relevant, including, without limitation,
the breadth of the market in the security, the price of the security, the
financial condition and execution capability of the brokers or dealers and the
reasonableness of the commission, if any, for the specific transaction and on a
continuing basis. In selecting brokers or dealers to execute a particular
transaction, and in evaluating the best overall terms available, the SUB-ADVISER
is authorized to consider the brokerage and research services (within the
meaning of Section 28(e) of the Securities and Exchange Act of 1934, as amended)
provided to the Covered Funds and/or other accounts over which the SUB-ADVISER
or its affiliates exercise discretion.

         The SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of services
under this Agreement. The SUB-ADVISER will make available to VALIC and the FUND
promptly upon their request all of the Covered Funds' investment records and
ledgers to assist VALIC and the FUND in complying with regulations applicable to
each Covered Fund's securities transactions as required by the 1940 Act and the
Advisers Act, as well as other applicable laws. The SUB-ADVISER will furnish the
FUND's Board of Trustees such periodic and special reports as VALIC and the
FUND's Board of Trustees may reasonably request. The SUB-ADVISER will furnish to
regulatory authorities any information or reports in connection with such
services which may be requested in order to ascertain whether the operations of
the Covered Funds are being conducted in a manner consistent with applicable
laws and regulations. The SUB-ADVISER will not disclose or use any records or
information obtained pursuant to this Agreement in any manner whatsoever except
as expressly authorized in this Agreement, and will keep confidential any
information obtained pursuant to this service relationship, and disclose such
information only if VALIC or the Board of Trustees of the FUND has authorized
such disclosure, or if such information is or hereafter becomes ascertainable
from public or published information or trade sources, or if such disclosure is
expressly required or requested by applicable federal or state authorities.


         The SUB-ADVISER will not hold money or investments on behalf of the
FUND. The money and investments will be held by the Custodian of the FUND. The
SUB-ADVISER will arrange for the transmission to the Custodian for the FUND, on
a daily basis, such confirmation, trade tickets and other documents as may be
necessary to enable it to perform its administrative responsibilities with
respect to the Covered Funds.

         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.

         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in furtherance
of the SUB-ADVISER's duties and responsibilities as set forth in this Agreement.


                                        2

<PAGE>   3




         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities hereunder
and VALIC shall pay, or arrange for others to pay, all VALIC's expenses, except
that VALIC shall in all events pay the compensation described in Section 2 of
this Agreement.


2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB-ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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. VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than thirty
(30) days following the end of the month.

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

         The payment of advisory fees related to the services of the SUB-ADVISER
under this Agreement shall be the sole responsibility of VALIC and shall not be
the responsibility of the FUND.

3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         VALIC understands that the SUB-ADVISER and its affiliates now act, will
continue to act and may act in the future as investment adviser to fiduciary and
other managed accounts and as investment adviser to other investment companies,
and VALIC has no objection to the SUB-ADVISER so acting, provided that whenever
a Covered Fund and one or more other accounts or investment companies advised by
the SUB-ADVISER have available funds for investment, investments suitable and
appropriate for each will be allocated in accordance with a methodology believed
to be equitable to each entity. The SUB-ADVISER similarly agrees to allocate
opportunities to sell securities. VALIC recognizes that, in some cases, this
procedure may limit the size of the position that may be acquired or sold for a
Covered Fund. In addition, VALIC understands that the persons employed by the
SUB-ADVISER to assist in the performance of the SUB-ADVISER's duties hereunder
will not devote their full time to such service and nothing contained herein
shall be deemed to limit or restrict the right of the SUB-ADVISER or any
affiliate of the SUB-ADVISER to engage in and devote time and attention to
other business or to render services of whatever kind or nature.

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

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this Agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER.

5.       TERM OF AGREEMENT

         This Agreement shall become effective as to the Fund(s) set forth on
Schedule A on the date hereof and as to any other Fund on the date of the
Amendment to Schedule A adding such Fund in accordance with this Agreement.
Unless sooner terminated as provided herein, this Agreement shall continue in
effect for two years from its effective 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, as that term is defined in the 1940 Act, or in the event of the
termination of the Investment Advisory Agreement between VALIC and the FUND as
it relates to any Covered Fund. The Agreement may be terminated as to any
Covered Fund at any time, without the payment of any penalty, by vote of the
FUND's Board of Trustees or by vote of a majority of that Covered Fund's


                                        4

<PAGE>   5



outstanding voting securities on at least 60 days' prior written notice to the
SUB-ADVISER. This Agreement may also be terminated by VALIC: (i) on at least 60
days' prior written notice to the SUB-ADVISER, without the payment of any
penalty; or (ii) if the SUB-ADVISER becomes unable to discharge its duties and
obligations under this Agreement. The SUB-ADVISER may terminate this Agreement
at any time, or preclude its renewal without the payment of any penalty, on at
least 60 days' prior written notice to VALIC.


6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act. The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property. The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder. The SUB-ADVISER further agrees to
preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records
required to be maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to
furnish SUB-ADVISER copies of any amendments or supplements thereto before or at
the time the amendments or supplements become effective.

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND in writing
signed or sent by any of the persons whose names, addresses and specimen
signatures will be provided by VALIC from time to time. The SUB-ADVISER shall
not be liable for so acting in good faith upon such instructions, confirmation
or authority, notwithstanding that it shall subsequently be shown that the same
was not given or signed or sent by an authorized person.

         VALIC agrees to furnish the SUB-ADVISER at its principal office prior
to use thereof, copies of all prospectuses, proxy statements, reports to
shareholders, sales literature, or other material prepared for distribution to
interest holders of the FUND or the public that refer in any way to the
SUB-ADVISER, and not to use such material if the SUB-ADVISER reasonably objects
in writing within ten (10) business days (or such other time as may be mutually
agreed) after receipt thereof. In the event of termination of this agreement,
VALIC will continue to furnish to the SUB-ADVISER copies of any of the
above-mentioned materials that refer in any way to the SUB-ADVISER. VALIC shall
furnish or otherwise make available to the SUB-ADVISER such other information
relating to the business affairs of VALIC and the FUND as the SUB-ADVISER at any
time, or from time to time, may reasonably request in order to discharge
obligations hereunder.

         VALIC agrees to indemnify the SUB-ADVISER for losses and claims which
arise (i) as a result of a failure by VALIC to provide the services or furnish
materials required under the terms of this Investment Sub-Advisory Agreement, or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, advertisements or sales literature,
pertaining to the FUND, except insofar as any such statement or omission was
made in reliance on information provided in writing by the SUB-ADVISER or its
affiliates.



                                        5

<PAGE>   6



         The SUB-ADVISER shall indemnify and hold harmless VALIC (and its
affiliated companies and their respective officers, directors and employees)
from any and all claims, losses, liabilities or damages (including reasonable
attorney's fees and other related expenses) arising out of or in connection with
(1) any willful misfeasance, bad faith, gross negligence, or reckless disregard
of obligations or duties of the SUB-ADVISER in performing hereunder; or (2) any
untrue statement of material fact or any omission to state a material fact
required to be stated or necessary to make statements, in light of the
circumstances under which they are made, not misleading in any registration
statement, proxy materials, advertisements or sales literature, pertaining to
the Funds to the extent any such statement or omission was made in reliance on
information provided in writing by the SUB-ADVISER to VALIC for the express
purpose of inclusion in such materials.


7.       APPLICABILITY OF FEDERAL SECURITIES LAWS

         This Agreement shall be interpreted in accordance with the laws of the
State of Texas and applicable federal securities laws and regulations, including
definitions therein and such exemptions as may be granted to VALIC or the
SUB-ADVISER 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

                        INVESTMENT SUB-ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as "VALIC," and CAPITAL
GUARDIAN TRUST COMPANY, hereinafter referred to as the "SUB-ADVISER."

         VALIC and the SUB-ADVISER recognize the following:

                  (a) VALIC is a life insurance company organized under Chapter
         3 of the Texas Insurance Code and an investment adviser registered
         under the Investment Advisers Act of 1940, as amended ("Advisers Act").

                  (b) VALIC is engaged as the investment adviser of American
         General International Value Fund, American General Domestic Bond Fund
         and American General Balanced Fund pursuant to an Investment Advisory
         Agreement dated August 26, 1998 between VALIC and American General
         Series Portfolio Company 3 ("FUND"), 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 a diversified, open-end,
         management investment company under the Investment Company Act of 1940,
         as amended ("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
         ("Funds"): American General International Value Fund, American General
         International Growth Fund, American General Large Cap Value Fund,

         Fund, American General Mid Cap Growth Fund, American General Small Cap
         Value Fund, American General Small Cap Growth Fund, American General
         Socially Responsible Fund, American General Money Market Fund, American
         General Domestic Bond Fund, American General Balanced Fund, American
         General Conservative Growth Lifestyle Fund, American General Moderate
         Growth Lifestyle Fund, American General Growth Lifestyle Fund, American
         General Core Bond Fund, American General Strategic Bond Fund, and
         American General High Yield Bond Fund. In accordance with the FUND's
         Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A, and any other
         Funds as may be added or deleted by amendment to the attached Schedule
         A ("Covered Funds").

                  (d) The SUB-ADVISER is engaged principally in the business of
         rendering investment advisory services and is exempt from registration
         as an investment adviser under the Advisers Act.

                  (e) VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign to
         the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with provisions of: (i)
the 1940 Act; (ii) all applicable laws and regulations thereunder; and (iii) all
other applicable federal and state laws and regulations, including section
817(h) of the Internal Revenue Code of 1986, as amended (the "Code"), as are set
forth in the Fund's Compliance Manual as mutually agreed upon by VALIC and the
SUB-ADVISER and in conformity with the FUND's Declaration, Bylaws, registration
statements, prospectus


                                        1

<PAGE>   2



and stated investment objectives, policies and restrictions and any applicable
procedures adopted by the FUND's Board of Trustees, which are communicated in
writing to the SUB-ADVISER, shall:

                  (a) manage the investment and reinvestment of the assets,
         other than the investment of cash, 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 orders for the purchase
         and sale of portfolio investments (which may include futures contracts
         and options thereon) for each Covered Fund's account with brokers or
         dealers (which may include futures commission merchants) selected by
         the SUB-ADVISER, or arrange for any other entity to provide a trading
         desk and to place orders with brokers and dealers (which may
         include futures commission merchants) selected by the SUB-ADVISER,
         which brokers or dealers may include brokers or dealers (which may
         include futures commission merchants) affiliated with the SUB-ADVISER,
         subject to applicable law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution. Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 SUB-ADVISER. The
SUB-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 SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of services
under this Agreement. The SUB-ADVISER will make available to VALIC and the FUND
promptly upon their request all of the Covered Funds' investment records and
ledgers to assist VALIC and the FUND in compliance with respect to each Covered
Fund's securities transactions as required by the 1940 Act and the Advisers Act,
as well as other applicable laws. The SUB-ADVISER will furnish the FUND's Board
of Trustees such periodic and special reports as VALIC and the FUND's Board of
Trustees may reasonably request. The SUB-ADVISER will furnish to regulatory
authorities any information or reports in connection with such services which
may be requested in order to ascertain whether the operations of the Covered
Funds are being conducted in a manner consistent with applicable laws and
regulations. The SUB-ADVISER will not disclose or use any records or information
obtained pursuant to this Agreement in any manner whatsoever except as expressly
authorized in this Agreement, and will keep confidential any information
obtained pursuant to this service relationship, and disclose such information
only if VALIC or the Board of Trustees of the FUND has authorized such
disclosure, or if such information is or hereafter becomes ascertainable from
public or published information or trade sources, or if such disclosure is
required or requested by applicable federal or state authorities.

         Should VALIC at any time make any definite determination as to
investment policy and notify the SUB-ADVISER of such determination, the
SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination has
been revoked.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND. The money and investments will be held by the Custodian of the FUND. The
SUB-ADVISER will arrange for the transmission to the Custodian for the FUND, on
a daily basis, such confirmation, trade tickets and other documents as may be
necessary to enable it to perform its administrative responsibilities with
respect to the Covered Funds.

         The SUB-ADVISER will not invest cash for the Covered Funds. The
investment of cash will be performed by VALIC.


                                        2

<PAGE>   3

         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in furtherance
of the SUB-ADVISER's duties and responsibilities as set forth in this Agreement.

         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities hereunder
and VALIC shall pay, or arrange for others to pay, all VALIC's expenses, except
that VALIC shall in all events pay the compensation described in Section 2 of
this Agreement.

2.       COMPENSATION OF THE SUB-ADVISER


         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB-ADVISER, a quarterly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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. VALIC shall pay this fee for each calendar quarter as soon as
practicable after the end of that quarter but in any event no later than thirty
(30) days following the end of the quarter.

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

         The payment of advisory fees related to the services of the SUB-ADVISER
under this Agreement shall be the sole responsibility of VALIC and shall not be
the responsibility of the FUND.

3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered Funds.

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this Agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER.

5.       TERM OF AGREEMENT

         This Agreement shall become effective as to the Fund(s) set forth on
Schedule A on the date hereof and as to any other Fund on the date of the
Amendment to Schedule A adding such Fund in accordance with this Agreement.
Unless sooner terminated as provided herein, this Agreement shall continue in
effect for two years from its effective 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, as that term is defined in the 1940 Act, or in the event of the
termination of the Investment Advisory Agreement between VALIC and the FUND as
it relates to any Covered Fund. The Agreement may be terminated as to any
Covered Fund at any time, without the payment of any penalty, by vote of the
FUND's Board of Trustees or by vote of a majority of that Covered Fund's
outstanding voting securities on at least 60 days' prior written notice to the
SUB-ADVISER. This Agreement may also be terminated by VALIC: (i) on at least 60
days' prior written notice to the SUB-ADVISER, without the payment of any
penalty; or (ii) if the SUB-ADVISER becomes unable to discharge its duties and
obligations under this Agreement. The SUB-ADVISER may terminate this Agreement
at any time, or preclude its renewal without the payment of any penalty, on at
least 60 days' prior written notice to VALIC.

6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act. The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property. The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder. The SUB-ADVISER further agrees to
preserve for the


                                        4

<PAGE>   5



periods prescribed by Rule 31a-2 under the 1940 Act the records required to be
maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to
furnish the SUB-ADVISER copies of any amendments or supplements thereto before
or at the time the amendments or supplements become effective.

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND in writing
signed or sent by any of the persons whose names, addresses and specimen
signatures will be provided by VALIC from time to time. The SUB-ADVISER shall
not be liable for so acting in good faith upon such instructions, confirmation
or authority, notwithstanding that it shall subsequently be shown that the same
was not given or signed or sent by an authorized person.

         The parties agree that the name "Capital Guardian Trust Company," the
names of the SUB-ADVISER's affiliates within the Capital Group of Companies,
Inc., and any derivative or logo or trade or service mark, are the valuable
property of the SUB-ADVISER and its affiliates. VALIC shall have the right to
use such name(s), derivatives, logos, trade or service marks only with the prior
written approval of the SUB-ADVISER, which approval shall not be unreasonably
withheld so long as this Agreement is in effect. Upon termination of this
Agreement, VALIC shall forthwith cease to use such name(s), derivatives, logos,
trade or service marks. VALIC agrees that it will review with the SUB-ADVISER
any advertisement, sales literature or notice prior to its use that makes
reference to the SUB-ADVISER so that the SUB-ADVISER may review the context in
which it is referred to, it being agreed that the SUB-ADVISER shall have no
responsibility to ensure the adequacy of the form or content of such materials
for purposes of the 1940 Act or other applicable laws and regulations. If the
Covered Funds or VALIC makes any unauthorized use of the SUB-ADVISER's name(s),
derivatives, logos, trade or service marks, the parties acknowledge that the
SUB-ADVISER shall suffer irreparable harm for which monetary damages are
inadequate and thus, the SUB-ADVISER shall be entitle to injunctive relief.
VALIC shall furnish or otherwise make available to the SUB-ADVISER such other
information relating to the business affairs of VALIC and the FUND as the
SUB-ADVISER at any time, or from time to time, may reasonably request in order
to discharge obligations hereunder.

         The SUB-ADVISER shall indemnify and hold harmless VALIC (and its
affiliated companies and their respective officers, directors and employees)
from any and all claims, losses, liabilities or damages (including reasonable
attorney's fees and other related expenses) arising out of or in connection with
(1) any willful misfeasance, bad faith, gross negligence, or reckless disregard
of obligations or duties of the SUB-ADVISER in performing hereunder; or (2) any
untrue statement of a material fact or any omission to state a material fact
required to be stated or necessary to make statements, in light of the
circumstances under which they are made, not misleading in any registration
statement, proxy materials, reports, advertisements, sales literature, or other
materials pertaining to the Funds to the extent any such statement or omission
was made in reliance on information provided by the SUB-ADVISER to VALIC for the
express purpose of inclusion in such materials.

         VALIC shall indemnify and hold harmless the SUB-ADVISER (and its
affiliated companies and their respective officers, directors and employees)
from any and all claims, losses, liabilities or damages (including reasonable
attorney's fees and other related expenses) arising out of any matter which does
not require the SUB-ADVISER to provide an indemnity under the preceding
paragraph, including without limitation, any claim that is based upon any untrue
statement of a material fact or any omission to state a material fact required
to be stated or necessary to make statements, in light of the circumstances
under which they are made, not misleading not misleading contained in the
registration statement, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to the Funds except those statements
that were provided by the SUB-ADVISER to VALIC for the express purpose of
inclusion in such materials.

SUB-ADVISER 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

         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 a diversified, open-end,
         management investment company under the Investment Company Act of 1940,
         as amended ("1940 Act"). The 1940 Act prohibits any person from acting
         as an investment adviser of a registered investment company except

         American General Large Cap Growth Fund, American General Mid Cap Value
         Fund, American General Mid Cap Growth Fund, American General Small Cap
         Value Fund, American General Small Cap Growth Fund, American General
         Socially Responsible Fund, American General Money Market Fund, American
         General Domestic Bond Fund, American General Balanced Fund, American
         General Conservative Growth Lifestyle Fund, American General Moderate
         Growth Lifestyle Fund, American General Growth Lifestyle Fund, American
         General Core Bond Fund, American General Strategic Bond Fund, and
         American General High Yield Bond Fund. In accordance with the FUND's
         Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A, and any other
         Funds as may be added or deleted by amendment to the attached Schedule
         A ("Covered Funds").

                  (d) The SUB-ADVISER is engaged in the business of rendering
         investment advisory services and is a "bank" as defined under the
         Advisers Act.

                  (e) VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign to
         the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with the 1940 Act, all
applicable laws and regulations thereunder, all other applicable federal and
state laws and regulations, including section 817(h) of the Internal Revenue
Code of 1986, as amended (the "Code"), the FUND's Declaration, Bylaws,
registration statements, prospectus and stated investment objectives, policies
and


                                        1

<PAGE>   2



restrictions and any applicable procedures adopted by the FUND's Board of
Trustees and provided to the SUB-ADVISER shall:

                  (a) manage the investment and reinvestment of the assets,
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon) for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB-ADVISER, subject to applicable law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution. Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 SUB-ADVISER. The
SUB-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 SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of services
under this Agreement. The SUB-ADVISER will make available to VALIC and the FUND
promptly upon their request all of the Covered Funds' investment records and
ledgers to assist VALIC and the FUND in compliance with respect to each Covered
Fund's securities transactions as required by the 1940 Act and the Advisers Act,
as well as other applicable laws. The SUB-ADVISER will furnish the FUND's Board
of Trustees such periodic and special reports as VALIC and the FUND's Board of
Trustees may reasonably request. The SUB-ADVISER will furnish to regulatory
authorities any information or reports in connection with such services which
may be requested in order to ascertain whether the operations of the Covered
Funds are being conducted in a manner consistent with applicable laws and
regulations. The SUB-ADVISER will not disclose or use any records or information
obtained pursuant to this Agreement in any manner whatsoever except as expressly
authorized in this Agreement, and will keep confidential any information
obtained pursuant to this service relationship, and disclose such information
only if VALIC or the Board of Trustees of the FUND has authorized such
disclosure, or if such information is or hereafter becomes ascertainable from
public or published information or trade sources, or if such disclosure is
expressly required or requested by applicable federal or state authorities.

         Should VALIC at any time make any definite determination as to
investment policy and notify the SUB-ADVISER of such determination in writing,
the SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination has
been revoked.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND. The money and investments will be held by the Custodian of the FUND (the
"Custodian"). The SUB-ADVISER will arrange for the transmission to the Custodian
for the FUND, on a daily basis, such confirmation, trade tickets and other
documents as may be necessary to enable it to perform its administrative
responsibilities the with respect to the Covered Funds. The SUB-ADVISER further
shall have the authority to instruct the custodian of the FUND (i) to pay cash
for securities and other property delivered to the Custodian for the FUND (ii)
to deliver securities and other property against payment for the FUND, and (iii)
to transfer assets and funds to such brokerage accounts as the SUB-ADVISER may
designate, all


                                        2

<PAGE>   3



consistent with the powers, authorities and limitations set forth herein. The
SUB-ADVISER shall not have the authority to cause the Custodian to deliver
securities and other property except as expressly provided for in this
Agreement.

         The SUB-ADVISER may aggregate sales and purchase orders of securities
held by the FUND with similar orders being made simultaneously for other
accounts managed by the SUB-ADVISER or with accounts of the affiliates of the
SUB-ADVISER, if in the SUB-ADVISER's reasonable judgment such aggregation shall
result in an overall economic benefit to the FUND considering the advantageous
selling or purchase price, brokerage commission and other expenses. In
accounting for such aggregated order price, commission and other expenses shall
be averaged on a per bond or share basis daily. VALIC acknowledges that the
determination of such economic benefit to the FUND by the SUB-ADVISER is
subjective and represents the SUB-ADVISER's evaluation that the FUND is
benefited by relatively better purchase or sales prices, lower commission
expenses and beneficial timing of transactions or a combination of these and
other factors.

         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.

         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in furtherance
of the SUB-ADVISER's duties and responsibilities as set forth in this Agreement.

         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities hereunder
and VALIC shall pay, or arrange for others to pay, all VALIC's expenses, except
that VALIC shall in all events pay the compensation described in Section 2 of
this Agreement.


2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB-ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and in the fee schedule attached hereto as Schedule
A. Schedule A may be amended from time to time with the express written consent
of the parties hereto, 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 new or existing 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.

         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. VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than thirty
(30) days following the end of the month.

         If the SUB-ADVISER terminates its services prior to month end, the
foregoing compensation shall be prorated.

         The payment of advisory fees related to the services of the SUB-ADVISER
under this Agreement shall be the sole responsibility of VALIC and shall not be
the responsibility of the FUND.


3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered Funds.
VALIC agrees that the


                                        3

<PAGE>   4



SUB-ADVISER may give advice and take action in the performance of its duties
with respect to any of its other clients which differ from action taken with
respect to any Covered Fund.

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

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER.

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

<PAGE>   5



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

6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act. The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property. The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder. The SUB-ADVISER further agrees to
preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records
required to be maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to
furnish the SUB-ADVISER copies of any amendments or supplements thereto before
or at the time the amendments or supplements become effective.

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND in writing
signed or sent by any of the persons whose names, addresses and specimen
signatures will be provided by VALIC from time to time. The SUB-ADVISER shall
not be liable for so acting in good faith upon such instructions, confirmation
or authority, notwithstanding that it shall subsequently be shown that the same
was not given or signed or sent by an authorized person.

         VALIC agrees to furnish the SUB-ADVISER at its principal office prior
to use thereof, copies of all prospectuses, proxy statements, reports to
shareholders, sales literature, or other material prepared for distribution to
interest holders of the FUND or the public that refer in any way to the
SUB-ADVISER, and not to use such material if the SUB-ADVISER reasonably objects
in writing within ten (10) business days (or such other time as may be mutually
agreed) after receipt thereof. In the event of termination of this agreement,
VALIC will continue to furnish to the SUB-ADVISER copies of any of the
above-mentioned materials that refer in any way to the SUB-ADVISER. VALIC shall
furnish or otherwise make available to the SUB-ADVISER such other information
relating to the business affairs of VALIC and the FUND as the SUB-ADVISER at any
time, or from time to time, may reasonably request in order to discharge
obligations hereunder.

         VALIC agrees to indemnify the SUB-ADVISER for losses and claims which
arise (i) as a result of a failure by VALIC to provide the services or furnish
materials required under the terms of this Investment Sub-Advisory Agreement, or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not


                                        5

<PAGE>   6
misleading in any registration statements, proxy materials, reports,
advertisements, sales literature, or other materials pertaining to the FUND,
except insofar as any such statement or omission was made in reliance on
information provided by the SUB-ADVISER or its affiliates.

         The SUB-ADVISER agrees to indemnify VALIC for losses and claims which
arise (i) as a result of a failure by SUB-ADVISER to provide the services or
furnish the materials required under the terms of this Investment Sub- Advisory
Agreement, including a negligent failure whether unintentional or in good faith
or otherwise, to comply with the diversification requirements specified in
section 817(h), and the qualification standards of Subchapter M of the Code, as
amended, and the regulations thereunder, (other than a failure which is
subsequently timely corrected by the SUB- ADVISER in accordance with applicable
law and regulations such that no loss is incurred by VALIC or a Covered Fund) or
(ii) as the result of any untrue statement of a material fact or any omission to
state a material fact required to be stated or necessary to make the statements,
in light of the circumstances under which they were made, not misleading in any
registration statements, proxy materials, reports, advertisements, sales
literature, or other materials pertaining to the FUND to the extent any such
statement or omission was made in reliance on information provided by the SUB-
ADVISER or its affiliates.

State of Texas and applicable federal securities laws and regulations, including
definitions therein and such exemptions as may be granted to VALIC or the
SUB-ADVISER 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.

                       INVESTMENT SUB-ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as "VALIC," and
NEUBERGER&BERMAN MANAGEMENT, INC., hereinafter referred to as the
"SUB-ADVISER."

         VALIC represents the following:

                 (a)  VALIC is a life insurance company organized under Chapter
         3 of the Texas Insurance Code and an investment adviser registered
         under the Investment Advisers Act of 1940, as amended ("Advisers
         Act").

                 (b)  VALIC is engaged as the investment adviser of American
         General Mid Cap Value Fund  pursuant to an Investment Advisory
         Agreement  dated August 26, 1998 between VALIC and American General
         Series Portfolio Company 3 ("FUND"), 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 a diversified, open-end,
         management investment company under the Investment Company Act of
         1940, as amended ("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
         ("Funds"): American General International Value Fund, American General
         International Growth Fund, American General Large Cap Value Fund,
         American General Large Cap Growth Fund, American General Mid Cap Value
         Fund,  American General Mid Cap Growth Fund, American General Small
         Cap Value Fund, American General Small Cap Growth Fund, American
         General Socially Responsible Fund, American General Money Market Fund,
         American General Domestic Bond Fund, American General Balanced Fund,
         American General Conservative Growth Lifestyle Fund, American General
         Moderate Growth Lifestyle Fund, American General Growth Lifestyle
         Fund, American General Core Bond Fund, American General Strategic Bond
         Fund, and American General High Yield Bond Fund.   In accordance with
         the FUND's Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A,
         and any other Funds as may be added or deleted by amendment to the
         attached Schedule A ("Covered Funds").

                 (d)  VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Fund(s) set forth on the attached Schedule A, and any other Funds
         as may be added or deleted by amendment to the attached Schedule A
         ("Covered Funds") which VALIC determines from time to time to assign
         to the SUB-ADVISER.

                 (e)  The SUB-ADVISER represents that it  is engaged
         principally in the business of rendering investment advisory services
         and is registered as an investment adviser under the Advisers Act.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

                 This Agreement will apply only to the Covered Funds.

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with the 1940 Act, all
applicable laws and regulations thereunder, all other applicable federal and
state laws and regulations, including section 817(h) of the Internal Revenue
Code of 1986, as amended (the "Code"),





                                       1
<PAGE>   2
the FUND's Declaration, Bylaws, registration statements, prospectus and stated
investment objectives, policies and restrictions and any applicable procedures
adopted by the FUND's Board of Trustees shall:

                 (a) manage the investment and reinvestment of the assets,
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon)  for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB- ADVISER, subject to applicable
         law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution.  Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 SUB-ADVISER.  The
SUB-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 SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of services
under this Agreement.  The SUB-ADVISER will make available to VALIC and the
FUND promptly upon their reasonable request all of the Covered Funds'
investment records and ledgers to assist VALIC and the FUND in compliance with
respect to each Covered Fund's securities transactions as required by the 1940
Act and the Advisers Act, as well as other applicable laws.  The SUB-ADVISER
will furnish the FUND's Board of Trustees such periodic and special reports as
VALIC and the FUND's Board of Trustees may reasonably request.  The SUB-ADVISER
will furnish to regulatory authorities any information or reports in connection
with such services which may be requested in order to ascertain whether the
operations of the Covered Funds are being conducted in a manner consistent with
applicable laws and regulations.  The SUB-ADVISER will not disclose any records
or information obtained pursuant to this Agreement in any manner whatsoever
except as expressly authorized in this Agreement, and will keep confidential
any information obtained pursuant to this service relationship, and disclose
such information only if VALIC or the Board of Trustees of the FUND has
authorized such disclosure, or if such information is or hereafter becomes
ascertainable from public or published information or trade sources, or if such
disclosure is expressly required or requested by applicable federal or state
authorities. Notwithstanding the foregoing, the SUB-ADVISER may disclose the
total return earned by the Covered Funds and may include such total return in
the calculation of composite performance information without prior approval by
VALIC or the Board of Trustees of the Fund.

         Should VALIC at any time make any definite determination as to
investment policy and notify the SUB-ADVISER of such determination in writing,
the SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination
has been revoked.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND.  The money and investments will be held by the Custodian of the FUND.
The SUB-ADVISER will arrange for the transmission to the Custodian for the
FUND, on a daily basis, such confirmation, trade tickets and other documents as
may be necessary to enable it to perform its administrative responsibilities
with respect to the Covered Funds.





                                       2
<PAGE>   3
         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.

         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in
furtherance of the SUB-ADVISER's duties and responsibilities as set forth in
this Agreement.


         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities
hereunder and VALIC shall pay, or arrange for others to pay, all VALIC's
expenses, except that VALIC shall in all events pay the compensation described
in Section 2 of this Agreement.

2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB- ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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.  VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than ten
(10) days following the end of the month.

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

         The payment of advisory  fees related to the services of the
SUB-ADVISER under this Agreement shall be the sole responsibility  of VALIC and
shall not be the responsibility of the FUND.

3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered
Funds.

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

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
claims, damages, liabilities or litigation (including reasonable counsel fees
and expenses) sustained in connection with the matters to which this Agreement
relates, so long as there has been no willful misfeasance, bad faith, gross
negligence, or reckless disregard of obligations or duties on the part of the
SUB-ADVISER.

         This Agreement shall become effective as to the Fund(s) set forth on

Unless sooner terminated as provided herein, this Agreement shall continue in
effect for two years from its effective date.  Thereafter, this Agreement shall
continue in effect, but with respect to any Covered Fund, subject to the

as such continuance is approved at least annually by the vote of a majority of

<PAGE>   5
The SUB-ADVISER may terminate this Agreement at any time, or preclude its
renewal without the payment of any penalty, on at least 60 days' prior written
notice to VALIC.

6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act.  The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property.  The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder.  The SUB-ADVISER further agrees to
preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the
records required to be maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to
furnish the SUB-ADVISER copies of any amendments or supplements thereto before
or at the time the amendments or supplements become effective.

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND in writing
signed or sent by any of the persons whose names, addresses and specimen
signatures will be provided by VALIC from time to time.  The SUB-ADVISER shall
not be liable for so acting in good faith upon such instructions, confirmation
or authority, notwithstanding that it shall subsequently be shown that the same
was not given or signed or sent by an authorized person.

         VALIC agrees to furnish the SUB-ADVISER at its principal office prior
to use thereof, copies of all prospectuses, proxy statements, reports to
shareholders, sales literature, or other material prepared for distribution to
interest holders of the FUND or the public that refer in any way to the
SUB-ADVISER, and not to use such material if the SUB-ADVISER reasonably objects
in writing within ten (10) business days (or such other time as may be mutually
agreed) after receipt thereof.  In the event of termination of this agreement,
VALIC will continue to furnish to the SUB-ADVISER copies of any of the
above-mentioned materials that refer in any way to SUB-ADVISER.  VALIC shall
furnish or otherwise make available to the SUB-ADVISER such other information
relating to the business affairs of VALIC and the FUND as the SUB-ADVISER at
any time, or from time to time, may reasonably request in order to discharge
obligations hereunder. Subject to provisions of this paragraph, SUB-ADVISER
grants VALIC and the FUND a non-exclusive right to use the "Neuberger&Berman"
name in connection with the SUB-ADVISER's management of the FUND (i) for so
long as the Agreement, any other investment management agreement between VALIC
and SUB-ADVISER with respect to the FUND, or to any extension, renewal or
amendment thereof, remain in effect, and (ii) for subsequent periods as long as
required by law, rule or regulation or to the extent necessary to refer to or
illustrate the historical performance of the FUND.

         VALIC agrees to indemnify the SUB-ADVISER for losses and claims which
arise (i) as a result of a failure by VALIC to provide the services or furnish
materials required under the terms of this Investment Sub-Advisory Agreement,
or (ii) as the result of any untrue statement of a material fact or any
omission to state a material fact required to be stated or necessary to make
the statements, in light of the circumstances under which they were made, not
misleading in any registration statements, proxy materials, reports,
advertisements, sales literature, or other materials





                                       5
<PAGE>   6
pertaining to the FUND, except insofar as any such statement or omission was
made in reliance on information provided by the SUB-ADVISER or its affiliates.

         The SUB-ADVISER agrees to indemnify VALIC for losses and claims which
arise (i) as a result of a failure by the SUB-ADVISER to provide the services
or furnish the materials required under the terms of this Investment
Sub-Advisory Agreement, including a negligent failure whether unintentional or
in good faith or otherwise, to comply with the diversification requirements
specified in section 817(h), and the qualification standards of Subchapter M of
the Code, as amended, and the regulations thereunder, (other than a failure
which is subsequently timely corrected by the SUB- ADVISER in accordance with
applicable law and regulations such that no loss is incurred by VALIC or a
Covered Fund) or (ii) as the result of any untrue statement of a material fact
or any omission to state a material fact required to be stated or necessary to
make the statements, in light of the circumstances under which they were made,
not misleading in any registration statements, proxy materials, reports,
advertisements, sales literature, or other materials pertaining to the FUND to
the extent any such statement or omission was made in reliance on information
provided by the SUB-ADVISER or its affiliates. Provided, however, that the
SUB-ADVISER's responsibility for indemnification pursuant to this paragraph
shall not, for any Covered Fund, exceed the lesser of $1,000,000 or 2% of the
Covered Fund's net assets (measured as of the end of the first calendar quarter
during which non-compliance occurred) for any failure to comply with the
diversification requirements specified in section 817(h) or the qualification
of Subchapter M of the Code.


7.       APPLICABILITY OF FEDERAL SECURITIES LAWS

         This Agreement shall be interpreted in accordance with the laws of the
State of Texas and applicable federal securities laws and regulations,
including definitions therein and such exemptions as may be granted to VALIC or
the SUB-ADVISER 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.

         The parties hereto have each caused this Agreement to be signed in
duplicate on its behalf by its duly authorized officer on the above date.

                       INVESTMENT SUB-ADVISORY AGREEMENT


This AGREEMENT made this 26th day of August, 1998, by and between THE VARIABLE
ANNUITY LIFE INSURANCE COMPANY, hereinafter referred to as "VALIC," and BANKERS
TRUST COMPANY, hereinafter referred to as the "SUB-ADVISER."

         VALIC and the SUB-ADVISER recognize the following:

                 (a)  VALIC is a life insurance company organized under Chapter
         3 of the Texas Insurance Code and an investment adviser registered
         under the Investment Advisers Act of 1940, as amended ("Advisers
         Act").

                 (b)  VALIC is engaged as the investment adviser of American
         General Small Cap Value Fund pursuant to an Investment Advisory
         Agreement  dated August 26, 1998 between VALIC and American General

         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 a diversified, open-end,
         management investment company under the Investment Company Act of
         1940, as amended ("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
         ("Funds"): American General International Value Fund, American General
         International Growth Fund, American General Large Cap Value Fund,
         American General Large Cap Growth Fund, American General Mid Cap Value
         Fund,  American General Mid Cap Growth Fund, American General Small
         Cap Value Fund, American General Small Cap Growth Fund, American
         General Socially Responsible Fund, American General Money Market Fund,
         American General Domestic Bond Fund, American General Balanced Fund,
         American General Conservative Growth Lifestyle Fund, American General
         Moderate Growth Lifestyle Fund, American General Growth Lifestyle
         Fund, American General Core Bond Fund, American General Strategic Bond
         Fund, and American General High Yield Bond Fund.   In accordance with
         the FUND's Agreement and Declaration of Trust (the "Declaration"), 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) set forth on the attached Schedule A,
         and any other Funds as may be added or deleted by amendment to the
         attached Schedule A ("Covered Funds").

                 (d)  The SUB-ADVISER is engaged in the business of rendering
         investment advisory services and is a "bank" as defined under the
         Advisers Act.

                 (e)  VALIC desires to enter into an Investment Sub-Advisory
         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign
         to the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in conformity with the 1940 Act, all
applicable laws and regulations thereunder, all other applicable federal and
state laws and regulations, including section 817(h) of the Internal Revenue
Code of 1986, as amended (the "Code"), the FUND's Declaration, Bylaws,
registration statements, prospectus and stated investment objectives, policies
and restrictions and any applicable procedures adopted by the FUND's Board of
Trustees shall:





                                       1
<PAGE>   2
                 (a) manage the investment and reinvestment of the assets,
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon)  for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB- ADVISER, subject to applicable
         law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the most
favorable overall price and execution.  Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 SUB-ADVISER.  The
SUB-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 SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of services
under this Agreement.  The SUB-ADVISER will make available to VALIC and the
FUND promptly upon their request all of the Covered Funds' investment records
and ledgers to assist VALIC and the FUND in compliance with respect to each
Covered Fund's securities transactions as required by the 1940 Act and the
Advisers Act, as well as other applicable laws. The SUB-ADVISER will furnish
the FUND's Board of Trustees such periodic and special reports as VALIC and the
FUND's Board of Trustees may reasonably request.  The SUB-ADVISER will furnish
to regulatory authorities any information or reports in connection with such
services which may be requested in order to ascertain whether the operations of
the Covered Funds are being conducted in a manner consistent with applicable
laws and regulations.  The SUB-ADVISER will not disclose or use any records or
information obtained pursuant to this Agreement in any manner whatsoever except
as expressly authorized in this Agreement, and will keep confidential any
information obtained pursuant to this service relationship, and disclose such
information only if VALIC or the Board of Trustees of the FUND has authorized
such disclosure, or if such information is or hereafter becomes ascertainable
from public or published information or trade sources, or if such disclosure is
expressly required or requested by applicable federal or state authorities or
to the extent such disclosure is reasonably required by auditors or attorneys
of the SUB-ADVISER in connection with the performance of their professional
services.

         Should VALIC at any time make any definite determination as to
investment policy and notify the SUB-ADVISER of such determination, the
SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination
has been revoked.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND.  The money and investments will be held by the Custodian of the FUND.
The SUB-ADVISER will arrange for the transmission to the Custodian for the
FUND, on a daily basis, such information with respect to transactions as may be
necessary to enable it to perform its administrative responsibilities with
respect to the Covered Funds.

         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.





                                       2
<PAGE>   3
         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act for or represent VALIC or the FUND other than in
furtherance of the SUB-ADVISER's duties and responsibilities as set forth in
this Agreement.

         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities
hereunder and VALIC shall pay, or arrange for others to pay, all VALIC's
expenses, except that VALIC shall in all events pay the compensation described
in Section 2 of this Agreement.

2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB- ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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.  VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than thirty
(30) days following the end of the month.


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

         The payment of advisory fees related to the services of the
SUB-ADVISER under this Agreement shall be the sole responsibility of VALIC and
shall not be the responsibility of the FUND.

3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered
Funds.

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

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER.

6.       OTHER MATTERS

         The SUB-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 no such person serves or
acts as an investment adviser separate from the SUB-ADVISER so as to require a
new written contract pursuant to the 1940 Act.  The compensation of any such
persons will be paid by the SUB-ADVISER, and no obligation will be incurred by,
or on behalf of, VALIC or the FUND with respect to them.

         The SUB-ADVISER agrees that all books and records which it maintains
for the FUND are the FUND's property.  The SUB-ADVISER also agrees upon request
of VALIC or the FUND, to promptly surrender the books and records in accordance
with the 1940 Act and rules thereunder.  The SUB-ADVISER further agrees to
preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the
records required to be maintained by Rule 31a-1 under the 1940 Act.

         VALIC has herewith furnished the SUB-ADVISER copies of the FUND's
Prospectus, Statement of Additional Information, Declaration and Bylaws as
currently in effect and agrees during the continuance of this Agreement to

         The SUB-ADVISER is authorized to honor and act on any notice,
instruction or confirmation given by VALIC on behalf of the FUND in writing
signed or sent by any of the persons whose names, addresses and specimen
signatures will be provided by VALIC from time to time.  The SUB-ADVISER shall
not be liable for so acting in good faith upon such instructions, confirmation
or authority, notwithstanding that it shall subsequently be shown that the same
was not given or signed or sent by an authorized person.

         VALIC agrees to furnish the SUB-ADVISER at its principal office prior
to use thereof, copies of all prospectuses, proxy statements, reports to
shareholders, sales literature, or other material prepared for distribution to
interest holders of the FUND or the public that refer in any way to the
SUB-ADVISER, and not to use such material if the SUB-ADVISER reasonably objects
in writing within ten (10) business days (or such other time as may be mutually
agreed) after receipt thereof.  In the event of termination of this agreement,
VALIC will continue to furnish to the SUB-ADVISER copies of any of the
above-mentioned materials that refer in any way to the SUB-ADVISER.  VALIC
shall furnish or otherwise make available to the SUB-ADVISER such other
information relating to the business affairs of VALIC and the FUND as the
SUB-ADVISER at any time, or from time to time, may reasonably request in order
to discharge obligations hereunder.

         VALIC agrees to indemnify the SUB-ADVISER for losses and claims which
arise (i) as a result of a failure by VALIC to provide the services or furnish
materials required under the terms of this Investment Sub-Advisory Agreement,
or (ii) as the result of any untrue statement of a material fact or any
omission to state a material fact required to be stated or necessary to make
the statements, in light of the circumstances under which they were made, not
misleading in any registration statements, proxy materials, reports,
advertisements, sales literature, or other materials pertaining to the FUND,
except insofar as any such statement or omission was made in reliance on
information provided by the the SUB-ADVISER or its affiliates.

         The SUB-ADVISER agrees to indemnify VALIC for losses and claims which
arise (i) as a result of a failure by the SUB-ADVISER to provide the services
or furnish the materials required under the terms of this Investment
Sub-Advisory Agreement, including a negligent failure whether unintentional or
in good faith or otherwise, to comply with the diversification requirements
specified in section 817(h), and the qualification standards of Subchapter M of
the Code, as amended, and the regulations thereunder, (other than a failure
which is subsequently timely corrected by the SUB- ADVISER in accordance with
applicable law and regulations such that no loss is incurred by VALIC or a
Covered Fund) or (ii) as the result of any untrue statement of a material fact
or any omission to state a material fact required to be stated or necessary to
make the statements, in light of the circumstances under which they were made,
not misleading in any registration statements, proxy materials, reports,
advertisements, sales literature, or other materials pertaining to





                                       5
<PAGE>   6
the FUND to the extent any such statement or omission was made in reliance on
information provided by the SUB-ADVISER or its affiliates.

7.       APPLICABILITY OF FEDERAL SECURITIES LAWS

         This Agreement shall be interpreted in accordance with the laws of the
State of Texas and applicable federal securities laws and regulations,
including definitions therein and such exemptions as may be granted to VALIC or
the SUB-ADVISER 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.

         attached Schedule A ("Covered Funds").

         Agreement with the SUB-ADVISER for all or a portion of the assets of
         the Covered Funds which VALIC determines from time to time to assign
         to the SUB-ADVISER.

         VALIC and the SUB-ADVISER AGREE AS FOLLOWS:

1.       SERVICES RENDERED AND EXPENSES PAID BY THE SUB-ADVISER

         The SUB-ADVISER, subject to the control, direction, and supervision of
VALIC and the FUND's Board of Trustees and in material conformity with the 1940
Act, all applicable laws and regulations thereunder, all other applicable
federal and state securities and tax laws and regulations, including section
817(h) and Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), the FUND's Declaration, Bylaws, registration statements,





                                       1
<PAGE>   2
prospectus and stated investment objectives, policies and restrictions and any
applicable procedures adopted by the FUND's Board of Trustees shall:

                 (a) manage the investment and reinvestment of the assets,
         other than cash, 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 orders for the purchase
         and sale of portfolio investments (including futures contracts and
         options thereon) for each Covered Fund's account with brokers or
         dealers (including futures commission merchants) selected by the
         SUB-ADVISER, or arrange for any other entity to provide a trading desk
         and to place orders with brokers and dealers (including futures
         commission merchants) selected by the SUB-ADVISER, subject to the
         SUB-ADVISER's control, direction, and supervision, which brokers or
         dealers may include brokers or dealers (including futures commission
         merchants) affiliated with the SUB- ADVISER, subject to applicable
         law.

         In performing the services described in paragraph (b) above, the
SUB-ADVISER shall use its best efforts to obtain for the Covered Funds the best
execution of portfolio transactions.  Subject to approval by the FUND's Board
of Trustees of appropriate policies and procedures, the SUB-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 to the SUB-ADVISER.  The SUB-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 in accordance with  such
authorization.

         The SUB-ADVISER shall maintain records adequately demonstrating
compliance with its obligations under this Agreement and report periodically to
VALIC and the FUND's Board of Trustees regarding the performance of its
services under this Agreement.  The SUB-ADVISER will make available to VALIC
and the FUND promptly upon their reasonable written request all of the Covered
Funds' investment records and ledgers to assist VALIC and the FUND in
compliance with respect to each Covered Fund's securities transactions as
required by the 1940 Act and the Advisers Act, as well as other applicable
laws.  The SUB-ADVISER will furnish the FUND's Board of Trustees such periodic
and special reports as VALIC and the FUND's Board of Trustees may reasonably
request.  The SUB-ADVISER will furnish to regulatory authorities any
information or reports in connection with such services which may be requested
in order to ascertain whether the operations of the Covered Funds are being
conducted in a manner consistent with applicable laws and regulations. The
SUB-ADVISER will not disclose or use any records or information obtained
pursuant to this Agreement in any manner whatsoever except as expressly
authorized in this Agreement, and will keep confidential any non-public
information obtained directly as a result of this service relationship, and the
SUN-ADVISER shall disclose such non-public information only if VALIC or the
Board of Trustees of the FUND has authorized such disclosure, or if such
information is or hereafter otherwise is known by the SUB-ADVISER or has been
disclosed, directly or indirectly, by VALIC or the Fund to others becomes
ascertainable from public or published information or trade sources, or if such
disclosure is expressly required or requested by applicable federal or state
regulatory authorities.

         Should VALIC at any time make any definite determination as to any
investment policy and notify the SUB-ADVISER in writing of such determination,
the SUB-ADVISER shall be bound by such determination for the period, if any,
specified in such notice or until similarly notified that such determination
has been revoked, provided such determination will permit SUB-ADVISER to comply
with the first paragraph of this Section.

         The SUB-ADVISER will not hold money or investments on behalf of the
FUND.  The money and investments will be held by the Custodian of the FUND.
The SUB-ADVISER will arrange for the transmission to the Custodian for the
FUND, on a daily basis, such confirmation, trade tickets and other documents as
may be necessary to enable it to perform its administrative responsibilities
with respect to the Covered Funds.

         The SUB-ADVISER will not perform cash management services for the
Covered Funds. The cash management function will be performed by VALIC.

         The SUB-ADVISER shall for all purposes herein be deemed to be an
independent contractor and shall, unless otherwise provided or authorized, have
no authority to act or represent VALIC or the Fund other than in furtherance of
the SUB- ADVISER's duties and responsibilities as set forth in this Agreement.

         Except as otherwise agreed, or as otherwise provided herein, the
SUB-ADVISER shall bear the expense of discharging its responsibilities
hereunder and VALIC shall pay, or arrange for others to pay, all VALIC's
expenses, except that VALIC shall in all events pay the compensation described
in Section 2 of the Agreement.

2.       COMPENSATION OF THE SUB-ADVISER

         VALIC shall pay to the SUB-ADVISER, as compensation for the services
rendered and expenses paid by the SUB- ADVISER, a monthly fee or fees based on
each Covered Fund's average monthly net asset value computed for each Covered
Fund as provided for herein and 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 new or existing
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.

         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.  VALIC shall pay this fee for each calendar month as soon as
practicable after the end of that month, but in any event no later than ten
(10) days following the end of the month.

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

         The payment of advisory fees related to the services of the
SUB-ADVISER under this Agreement shall be the sole concern of VALIC and the
SUB-ADVISER and shall not be the responsibility of the FUND.

3.       SCOPE OF THE SUB-ADVISER'S ACTIVITIES

         The SUB-ADVISER, and any person controlled by or under common control
with the SUB-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 SUB-ADVISER renders to the Covered
Funds.

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

         The SUB-ADVISER shall not be liable to VALIC, the FUND, or to any
shareholder in the FUND, and VALIC shall indemnify the SUB-ADVISER, for any act
or omission in rendering services under this Agreement, or for any losses
sustained in connection with the matters to which this agreement relates, so
long as there has been no willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties on the part of the SUB-ADVISER in
performing its duties under this Agreement.

any untrue statement of a material fact or any omission to state a material
fact required to be stated or necessary to make the statements, in light of the
circumstances under which they were made, not misleading in any registration

         THIS AGREEMENT made this 26th day of August, 1998 by and between
AMERICAN GENERAL SERIES PORTFOLIO COMPANY 3, a Delaware business trust,

THE FUND AND THE DISTRIBUTOR RECOGNIZE THE FOLLOWING:

1.       The Fund is registered as a diversified, open-end management
         investment company under the Investment Company Act of 1940 (the "1940
         Act"). The Fund consists of a number of investment portfolios, as may
         now exist and may hereinafter be established ("Portfolios"), as set
         forth on Schedule A hereto.  The Fund intends to continuously offer
         the shares of its various Portfolios for sale to The Variable Annuity
         Life Insurance Company Separate Account A, other separate accounts of
         VALIC, separate accounts of life insurance companies that are
         affiliated with VALIC, employee thrift plans maintained by VALIC or
         its affiliates, separate accounts of life insurance companies that are
         not affiliated with VALIC and, subject to applicable law, the public
         (all eligible purchasers of such shares being referred to collectively
         as the "Purchasers").  The Fund also intends that the Purchasers may
         provide certain beneficial ownership rights to individuals under
         variable annuity and variable life insurance contracts, employee
         thrift plans or other such arrangements (such individuals together
         with any Purchasers who retain all beneficial ownership rights being
         referred to collectively as the "Participants").  The Fund may suspend
         sales of the shares of any one or more Portfolios at any time, and may
         resume sales of any such Portfolio(s) at a later date.

2.       The Distributor is registered as a broker-dealer under the Securities
         Exchange Act of 1934 and is currently a member of the National
         Association of Securities Dealers, Inc. (the "NASD").

THE FUND AND THE DISTRIBUTOR AGREE AS FOLLOWS:

1.       The Fund hereby appoints the Distributor as principal underwriter and
         distributor to sell to the Purchasers the shares of the Portfolios
         (hereinafter "its shares" or "the Fund's shares").  The appointment of
         the Distributor hereunder shall not preclude the Fund from selling its
         shares directly to the Purchasers.

         the Fund's shares only on the terms set forth in the Fund's then
         current registration statement or related prospectus.

3.       The Fund has no load or redemption charge and the Distributor will
         receive no compensation for acting in such capacity.  Notwithstanding
         this, the Distributor assumes and will pay, from its own resources,
         all expenses related to distribution of the Fund's shares and will
         bear all other costs and expenses attributable to any activity

                          laws of any state or other jurisdiction in which the
                          Distributor may arrange for the sale of the Fund's
                          shares; and

                 (2)      The printing and distribution of the Fund's
                          prospectuses to existing Participants as may be
                          required under the federal securities laws and the
                          applicable securities laws of any state or other
                          jurisdiction; and

                 (3)      The preparation, printing and distribution of any
                          proxy statements, notices and reports, and the
                          performance of any acts required to be performed by
                          the Fund by and under the federal securities laws and
                          the applicable securities laws of any state or other
                          jurisdiction; and

                 (4)      The issuance of the Fund's shares, including any
                          share issue and transfer taxes.

         (b)     The Distributor will pay from its own resources (or will enter
                 into arrangements providing that persons other than the
                 Distributor or the Fund shall pay), or promptly reimburse the
                 Fund, for all expenses in connection with:

                 (1)      The printing and distribution of the Fund's
                          prospectuses utilized in the marketing of the
                          Portfolios to eligible Purchasers;

                 (2)      The preparation, printing and distribution of
                          advertising and sales literature for use in the

                          distribution of reports to Purchasers and/or
                          Participants used as sales literature;

                 (3)      The qualification of the Distributor as a distributor

                          state securities laws;

                 (4)      Any investment program of the Fund, including the
                          reinvestment of dividends and capital gains
                          distributions, to the extent such expenses exceed the
                          Fund's normal costs of issuing its shares; and

                 (5)      All other expenses in connection with offering for
                          sale and sale of the Fund's shares which have not
                          been herein specifically allocated to the Fund.

5.       Duties of the Distributor.

         (a)     The Distributor shall devote reasonable time and effort to
                 effect sales of the Fund's shares, but it shall not be
                 obligated to sell any specific number of shares.

         (b)     The Distributor shall use its best efforts in all respects
                 duly to conform with the requirements of all federal and state
                 laws and regulations and the regulations of the NASD, in
                 relating to the sale of such securities.  Neither the
                 Distributor nor any other person is authorized by the Fund to
                 give any information or to make any representations, other
                 than those contained in the Fund's then current registration
                 statement or related prospectus and any sales literature
                 authorized by responsible officers of the Distributor.

         (c)     The Distributor shall act as an independent contractor and
                 nothing herein contained shall constitute the Distributor, its
                 agents or representatives, or any employees thereof as
                 employees of the Fund in connection with the sale of the
                 Fund's shares.

                 The Distributor is responsible for its own conduct and the
                 employment, control and conduct of its agents and employees
                 and for injury to such agents or employees or to others
                 through its agents or employees.  The Distributor assumes full
                 responsibility for its agents and employees under applicable
                 statutes and agrees to pay all employer taxes thereunder.

6.       Sale and Redemption of the Fund's Shares

         (a)     Orders for the purchase and redemption of the Fund's shares
                 (and payment for the Fund's shares, in the case of a purchase)
                 shall be transmitted directly from the Purchaser to the Fund
                 or its agent.

         (b)     The Fund shall have the right to suspend the redemption of the
                 Fund's shares pursuant to the conditions set forth in the
                 Fund's then current registration statement or related
                 prospectus.  The Fund shall also have the right to suspend the
                 sale of the Fund's shares at any time.





                                       3
<PAGE>   4
         (c)     The Fund will give the Distributor prompt notice of any such
                 suspension and shall promptly furnish such other information
                 in connection with the sale and redemption of the Fund's
                 shares as the Distributor reasonably requests.

         (d)     The Fund (or its agent) will make appropriate book entries
                 upon receipt by the Fund (or its agent) of orders and payments
                 for the Fund's shares or requests for redemption thereof, and
                 will issue and redeem the Fund's shares and confirm such
                 transactions in accordance with applicable laws and
                 regulations.

7.       Indemnification.

                 The Distributor agrees to indemnify, defend and hold the Fund,
                 its officers and trustees (or former officers and trustees)
                 and any person who controls the Fund within the meaning of
                 Section 15 of the Securities Act of 1933 (the "1933 Act")
                 (collectively, "Indemnities") free and harmless from and
                 against any and all claims, demands, liabilities and expenses
                 (including the cost of investigating or defending such claims,
                 demands or liabilities and any counsel fees incurred in
                 connection therewith) incurred by any Indemnitee under the
                 1933 Act or under common law or otherwise, which arise out of
                 or are based upon (1) any untrue or alleged untrue statement
                 of a material fact or omission or alleged omission of a
                 material fact in information furnished by the Distributor to
                 the Fund's registration statement or related prospectus, (2)
                 any misrepresentation or omission or alleged misrepresentation
                 or omission to state a material fact on the part of the
                 Distributor or any agent or employee of the Distributor or any
                 other person for whose acts the Distributor is responsible or
                 is alleged to be responsible, unless such misrepresentation or
                 omission or alleged misrepresentation or omission was made in
                 reliance on written information furnished by the Fund, or (3)
                 the willful misconduct or failure to exercise reasonable care
                 and diligence on the part of any such persons with respect to
                 services rendered under this Agreement.  The foregoing rights
                 of indemnification shall be in addition to any other rights to
                 which any Indemnitee may be entitled as a matter of law.  The
                 Fund agrees promptly to notify the Distributor of any action
                 brought against any Indemnitee, such notification being given
                 to the Distributor by letter or telegram addressed to the
                 Distributor at its principal business office, and the
                 Distributor's agreement to indemnify the Indemnities pursuant
                 to this paragraph is expressly conditioned upon such
                 notification.

                 The Fund agrees to indemnify, defend and hold the Distributor,
                 its officers and trustees (or former officers and trustees)
                 and any person who controls the Distributor within the meaning
                 of Section 15 of the 1933 Act (collectively, "Indemnities")
                 free and harmless from and against any and all claims,
                 demands, liabilities and expenses (including the cost of
                 investigating or defending such claims, demands or liabilities
                 and any counsel fees incurred in connection therewith)
                 incurred by any Indemnitee

<PAGE>   5
                 under the 1933 Act or under common law or otherwise, arising
                 out of or based upon any alleged untrue statement of a
                 material fact contained in the Fund's registration statement
                 or related prospectus arising out of or based upon any alleged
                 omission to state a material fact required to be stated or
                 necessary to make the Fund's registration statement or related
                 prospectus not misleading, provided that in no event shall
                 anything contained in this Agreement be construed so as to
                 protect the Distributor against any liability to the Fund, the
                 Purchasers or the Participants to which the Distributor would
                 otherwise be subject by reason of willful misfeasance, bad
                 faith, or gross negligence in the performance of its duties,
                 or by reason of its reckless disregard of its obligations and
                 duties under this Agreement, and further provided that the
                 Fund shall not indemnify the Distributor for any claims,
                 demands, liabilities and expenses arising out of or based upon
                 any alleged untrue statement of a material fact or omission to
                 state a material fact in information furnished by the
                 Distributor to the Fund's registration statement or related
                 prospectus.

8.               This Agreement is effective as of August 26, 1998 and shall
                 continue in force from year-to-year thereafter, provided that
                 such continuance for more than two years is specifically
                 approved at least annually (a)(I) by the Board of Trustees of
                 the Fund, or (ii) by vote of a majority of the Fund's
                 outstanding voting securities (as defined in Section 2(a)(42)
                 of the 1940 Act), and (b) by the affirmative vote of a
                 majority of the Trustees who are not interested persons (as
                 defined in Section 2(a)(19) of the 1940 Act) of the Fund by
                 votes cast in person at a meeting called for such purpose.

9.               (a)      This Agreement may be terminated at any time, without
                          penalty, by a vote of the Board of Trustees of the
                          Fund or by a vote of a majority of the outstanding
                          voting securities of the Fund, or by the Distributor,
                          on sixty (60) days' written notice to the other
                          party.

                 (b)      This Agreement shall automatically terminate in the
                          event of its assignment, as defined in Section
                          2(a)(4) of the 1940 Act.

10.              Notwithstanding anything to the contrary contained in this
                 Agreement, the Fund acknowledges and agrees that, as provided
                 by Section 8.1 of the Fund's Agreement and Declaration of
                 Trust, 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, Purchasers or Participants
                 individually, but are 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 the State of
                 Delaware.

                               CUSTODIAN CONTRACT


         This Contract between AMERICAN GENERAL SERIES PORTFOLIO COMPANY 3, a
business trust organized and existing under the laws of Delaware, having its
principal place of business at 2929 Allen Parkway, Houston, Texas 77019,
hereinafter called the "Fund," and STATE STREET BANK AND TRUST COMPANY, a
Massachusetts trust company, having its principal place of business at 225
Franklin Street, Boston, Massachusetts 02110, hereinafter called the
"Custodian."

                                  WITNESSETH:

         WHEREAS, the Fund is authorized to issue shares in separate series,
with each such series representing interests in a separate portfolio of
securities and other assets;

         WHEREAS, the Fund intends to initially offer shares in eighteen (18)
series listed on Exhibit A hereto (such series together with all other series
subsequently established by the Fund and made subject to this Contract in
accordance with paragraph 19, being herein referred to as the "Portfolio(s)")
and desires to retain the Custodian to perform certain services therefor; and

         WHEREAS, certain Portfolios (hereinafter sometimes referred to as the
"Lifestyle Portfolio(s)") may invest in uncertificated shares of certain other
Portfolios or uncertificated shares of any registered investment company, or
series thereof, which is part of the same "group of investment companies" (as
defined in Section 12 of the Investment Company Act of 1940, as amended (the
"1940 Act")) (hereinafter sometimes referred to as the "Underlying
Portfolios").

         NOW, THEREFORE, in consideration of the mutual covenants and
agreements hereinafter contained, the parties hereto agree as follows:

1.       Employment of Custodian and Property to be Held by It

         The Fund hereby employs the Custodian as the custodian of the assets
of the Portfolios of the Fund, including securities which the Fund, on behalf
of the applicable Portfolio desires to be held in places within the United
States ("domestic securities") and securities it desires to be held outside the
United States ("foreign securities") pursuant to the provisions of the
Agreement and Declaration of Trust (the "Declaration of Trust"). The Fund on
behalf of the Portfolio(s) agrees to deliver to the Custodian all securities
and cash of the Portfolios, and all payments of income, payments of principal
or capital distributions received by it with respect to all securities owned by
the Portfolio(s) from time to time, and the cash consideration received by it
for such new or treasury shares of beneficial interest of the Fund representing
interests in the Portfolios, ("Shares") as may be issued or sold from time to
time. The Custodian shall not be responsible for any property of a Portfolio
held or received by the Portfolio and not delivered to the Custodian. With
respect to uncertificated shares of the Underlying Portfolios (the "Underlying
Shares") the holding of confirmation statements that identify the shares as
being recorded in the Custodian's name on behalf of the Lifestyle Portfolios
will be deemed custody for purposes hereof.

         Upon receipt of "Proper Instructions" (within the meaning of Article
5), the Custodian shall on behalf of the applicable Portfolio(s) from time to
time employ one or more sub-custodians, located in the United States but only
in accordance with an applicable vote by the Board of Trustees of the Fund on
behalf of the applicable Portfolio(s), and provided that the Custodian shall
have no more or less responsibility or liability to the Fund on account of any
actions or omissions of any sub-custodian so employed than any such
sub-custodian has to the Custodian. The Custodian may employ as sub-custodian
for the Fund's foreign securities on behalf of the applicable Portfolio(s) the
foreign banking institutions and foreign securities depositories designated in
Schedule A hereto but only in accordance with the provisions of Article 3.

         as Custodian in the Banking Department of the Custodian or in such
         other banks or trust companies as it may in its discretion deem
         necessary or desirable; provided, however, that every such bank or

         custom in the securities business, and shall collect on a timely basis
         all income and other payments with respect to bearer domestic
         securities if, on the date of payment by the issuer, such securities
         are held by the Custodian or its agent and shall credit such income,
         as collected, to such Portfolio's custodian account. Without limiting
         the generality of the foregoing, the Custodian shall detach and

         pursuant to a securities lending agreement with the Custodian, in

         Custodian. The Custodian will have no duty or responsibility in
         connection therewith, other than to provide the Fund with such



                                      5.

                  made.

2.8      Liability for Payment in Advance of Receipt of Securities Purchased.

         every case where payment for purchase of domestic securities for the
         account of a Portfolio is made by the Custodian in advance of receipt
         of the securities purchased in the absence of specific written
         instructions from the Fund on behalf of such Portfolio to so pay in
         advance, the Custodian shall be absolutely liable to the Fund for such
         securities to the same extent as if the securities had been received
         by the Custodian.

2.9      Appointment of Agents. The Custodian may at any time or times in its
         discretion appoint (and may at any time remove) any other bank or

         Act of 1940, as amended, to act as a custodian, as its agent to carry
         out such of the provisions of this Article 2 as the Custodian may from
         time to time direct; provided, however, that the appointment of any
         agent shall not relieve the Custodian of its responsibilities or
         liabilities hereunder. The Underlying Transfer Agent shall not be
         deemed an agent or subcustodian of the Custodian for purposes of this
         Section 2.9 or any other provision of this Contract.

                  transferred to the Account, and (ii) the making of an entry
                  on the records of the Custodian to reflect such payment and

                  to the Account, and (ii) the making of an entry on the
                  records of the Custodian to reflect such transfer and payment

         4)       The Custodian shall provide the Fund for the Portfolio with

                  System's accounting system, internal accounting control and
                  procedures for safeguarding securities deposited in the U.S.

                  the Custodian shall be liable to the Fund for the benefit of
                  the Portfolio for any loss or damage to the Portfolio
                  resulting from use of the U.S. Securities System by reason of
                  any negligence, misfeasance or misconduct of the Custodian or
                  any of its agents or of any of its or their employees or from
                  failure of the Custodian or any such agent to enforce
                  effectively such rights as it may have against the U.S.
                  Securities System; at the election of the Fund, it shall be
                  entitled to be subrogated to the rights of the Custodian with
                  respect to any claim against the U.S. Securities System or
                  any other person which the Custodian may have as a
                  consequence of any such loss or damage if and to the extent
                  that the Portfolio has not been made whole for any such loss
                  or damage.

2.10A    Deposit of Fund Assets with the Underlying Transfer Agent. Underlying
         Shares shall be deposited and/or maintained in an account or accounts

                  the records of the Custodian to reflect such payment and

                  on the records of the Custodian to reflect such transfer and
                  payment for the account of the Lifestyle Portfolio. The
                  Custodian will receive confirmation from the Underlying

                  Shares with the Underlying Transfer Agent except for losses
                  resulting directly from the negligence, misfeasance or

         Portfolio's securities and other assets maintained outside the United
         States the foreign banking institutions and foreign securities
         depositories designated on Schedule A hereto ("foreign
         sub-custodians"). Upon receipt of "Proper Instructions", as defined in
         Section 5 of this Contract, the Custodian and the Fund may agree to
         amend Schedule A hereto from time to time to designate additional
         foreign banking institutions and foreign securities depositories to
         act as sub-custodian. Upon



                                      11.
<PAGE>   12

         receipt of Proper Instructions, the Fund may instruct the Custodian to
         cease the employment of any one or more such sub-custodians for
         maintaining custody of the Fund's assets.

3.2      Assets to be Held. The Custodian shall limit the securities and other
         assets maintained in the custody of the foreign sub-custodians to: (a)
         "foreign securities", as defined in paragraph (c)(1) of Rule 17f-5
         under the Investment Company Act of 1940, and (b) cash and cash
         equivalents in such amounts as the Custodian or the Fund may determine
         to be reasonably necessary to effect the Portfolio's foreign
         securities transactions. The Custodian shall identify on its books as
         belonging to the Fund, the foreign securities of the Fund held by each
         foreign sub-custodian.

3.3      Foreign Securities Systems. Except as may otherwise be agreed upon in
         writing by the Custodian and the Fund, assets of the Portfolios shall
         be maintained in a clearing agency which acts as a securities
         depository or in a book-entry system for the central handling of
         securities located outside the United States (each a "Foreign
         Securities System") only through arrangements implemented by the
         foreign banking institutions serving as sub-custodians pursuant to the
         terms hereof (Foreign Securities Systems and U.S. Securities Systems
         are collectively referred to herein as the "Securities Systems").
         Where possible, such arrangements shall include entry into agreements
         containing the provisions set forth in Section 3.5 hereof.

3.4      Holding Securities. The Custodian may hold securities and other
         non-cash property for all of its customers, including the Fund, with a
         foreign sub-custodian in a single account that is identified as
         belonging to the Custodian for the benefit of its customers, provided
         however, that (i) the records of the Custodian with respect to
         securities and other non-cash property of the Fund which are
         maintained in such account shall identify by book-entry those
         securities and other non-cash property belonging to the Fund and (ii)
         the Custodian shall require that securities and other non-cash
         property so held by the foreign sub-custodian be held separately from
         any assets of the foreign sub-custodian or of others.

3.5      Agreements with Foreign Banking Institutions. Each agreement with a
         foreign banking institution shall provide that: (a) the assets of each
         Portfolio will not be subject to any right, charge, security interest,
         lien or claim of any kind in favor of the foreign banking institution
         or its creditors or agent, except a claim of payment for their safe
         custody or administration; (b) beneficial ownership for the assets of
         each Portfolio will be freely transferable without the payment of
         money or value other than for custody or administration; (c) adequate
         records will be maintained identifying the assets as belonging to each
         applicable Portfolio; (d) officers of or auditors employed by, or
         other representatives of the Custodian, including to the extent
         permitted under applicable law the independent public accountants for
         the Fund, will be given access to the books and records of the foreign
         banking institution relating to its actions under its agreement with
         the Custodian; and (e) assets of the Portfolios held by the foreign
         sub-custodian will be subject only to the instructions of the
         Custodian or its agents.



                                      12.

3.6      Access of Independent Accountants of the Fund. Upon request of the
         Fund, the Custodian will use its best efforts to arrange for the
         independent accountants of the Fund to be afforded access to the books
         and records of any foreign banking institution employed as a foreign
         sub-custodian insofar as such books and records relate to the
         performance of such foreign banking institution under its agreement
         with the Custodian.

3.7      Reports by Custodian. The Custodian will supply to the Fund from time
         to time, as mutually agreed upon, statements in respect of the
         securities and other assets of the Portfolio(s) held by foreign
         sub-custodians, including but not limited to an identification of
         entities having possession of the Portfolio(s) securities and other
         assets and advices or notifications of any transfers of securities to
         or from each custodial account maintained by a foreign banking
         institution for the Custodian on behalf of each applicable Portfolio
         indicating, as to securities acquired for a Portfolio, the identity of
         the entity having physical possession of such securities.

3.8      Transactions in Foreign Custody Account. (a) Except as otherwise
         provided in paragraph (b) of this Section 3.8, the provision of
         Sections 2.2 and 2.7 of this Contract shall apply, mutatis mutandis to
         the foreign securities of the Fund held outside the United States by
         foreign sub-custodians.

         (b) Notwithstanding any provision of this Contract to the contrary,
         settlement and payment for securities received for the account of each
         applicable Portfolio and delivery of securities maintained for the
         account of each applicable Portfolio may be effected in accordance
         with the customary established securities trading or securities
         processing practices and procedures in the jurisdiction or market in
         which the transaction occurs, including, without limitation,
         delivering securities to the purchaser thereof or to a dealer therefor
         (or an agent for such purchaser or dealer) against a receipt with the
         expectation of receiving later payment for such securities from such
         purchaser or dealer.

         (c) Securities maintained in the custody of a foreign sub-custodian
         may be maintained in the name of such entity's nominee to the same
         extent as set forth in Section 2.3 of this Contract, and the Fund
         agrees to hold any such nominee harmless from any liability as a
         holder of record of such securities.

3.9      Liability of Foreign Sub-Custodians. Each agreement pursuant to which
         the Custodian employs a foreign banking institution as a foreign
         sub-custodian shall require the institution to exercise reasonable
         care in the performance of its duties and to indemnify, and hold
         harmless, the Custodian and the Fund from and against any loss,
         damage, cost, expense, liability or claim arising out of or in
         connection with the institution's performance of such obligations. At
         the election of the Fund, it shall be entitled to be subrogated to the
         rights of the Custodian with respect to any claims against a foreign
         banking institution as a consequence of any such loss, damage, cost,
         expense, liability or claim if and to the extent that the Fund has not
         been made whole for any such loss, damage, cost, expense, liability or
         claim.



                                      13.

3.10     Liability of Custodian. The Custodian shall be liable for the acts or
         omissions of a foreign banking institution to the same extent as set
         forth with respect to sub-custodians generally in this Contract and,
         regardless of whether assets are maintained in the custody of a
         foreign banking institution, a foreign securities depository or a
         branch of a U.S. bank as contemplated by paragraph 3.13 hereof, the
         Custodian shall not be liable for any loss, damage, cost, expense,
         liability or claim resulting from nationalization, expropriation,
         currency restrictions, or acts of war or terrorism or any loss where
         the sub-custodian has otherwise exercised reasonable care.
         Nothwithstanding the foregoing provisions of this paragraph 3.10, in
         delegating custody duties to State Street London Ltd., the Custodian
         shall not be relieved of any responsibility to the Fund for any loss
         due to such delegation, except such loss as may result from (a)
         political risk (including, but not limited to, exchange control
         restrictions, confiscation, expropriation, nationalization,
         insurrection, civil strife or armed hostilities) or (b) other losses
         (excluding a bankruptcy or insolvency of State Street London Ltd. not
         caused by political risk) due to Acts of God, nuclear incident or
         other losses under circumstances where the Custodian and State Street
         London Ltd. have exercised reasonable care.

3.11     Reimbursement for Advances. If the Fund requires the Custodian to
         advance cash or securities for any purpose for the benefit of a
         Portfolio including the purchase or sale of foreign exchange or of
         contracts for foreign exchange, or in the event that the Custodian or
         its nominee shall incur or be assessed any taxes, charges, expenses,
         assessments, claims or liabilities in connection with the performance
         of this Contract, except such as may arise from its or its nominee's
         own negligent action, negligent failure to act or willful misconduct,
         any property at any time held for the account of the applicable
         Portfolio shall be security therefor and should the Fund fail to repay
         the Custodian promptly, the Custodian shall be entitled to utilize
         available cash and to dispose of such Portfolio's assets to the extent
         necessary to obtain reimbursement.

3.12     Monitoring Responsibilities. The Custodian shall furnish annually to
         the Fund, during the month of June, information concerning the foreign
         sub-custodians employed by the Custodian. Such information shall be
         similar in kind and scope to that furnished to the Fund in connection
         with the initial approval of this Contract. In addition, the Custodian
         will promptly inform the Fund in the event that the Custodian learns
         of a material adverse change in the financial condition of a foreign
         sub-custodian or any material loss of the assets of the Fund or in the
         case of any foreign sub-custodian not the subject of an exemptive
         order from the Securities and Exchange Commission is notified by such
         foreign sub-custodian that there appears to be a substantial
         likelihood that its shareholders' equity will decline below $200
         million (U.S. dollars or the equivalent thereof) or that its
         shareholders' equity has declined below $200 million (in each case
         computed in accordance with generally accepted U.S. accounting
         principles).

3.13     Branches of U.S. Banks. (a) Except as otherwise set forth in this
         Contract, the provisions hereof shall not apply where the custody of
         the Portfolios assets are maintained in a foreign



                                      14.
<PAGE>   15

         branch of a banking institution which is a "bank" as defined by
         Section 2(a)(5) of the Investment Company Act of 1940 meeting the
         qualification set forth in Section 26(a) of said Act. The appointment
         of any such branch as a sub-custodian shall be governed by paragraph 1
         of this Contract.

         (b) Cash held for each Portfolio of the Fund in the United Kingdom
         shall be maintained in an interest bearing account established for the
         Fund with the Custodian's London branch, which account shall be
         subject to the direction of the Custodian, State Street London Ltd. or
         both.

3.14     Tax Law. The Custodian shall have no responsibility or liability for
         any obligations now or hereafter imposed on the Fund or the Custodian
         as custodian of the Fund by the tax law of the United States of
         America or any state or political subdivision thereof. It shall be the
         responsibility of the Fund to notify the Custodian of the obligations
         imposed on the Fund or the Custodian as custodian of the Fund by the
         tax law of jurisdictions other than those mentioned in the above
         sentence, including responsibility for withholding and other taxes,
         assessments or other governmental charges, certifications and
         governmental reporting. The sole responsibility of the Custodian with
         regard to such tax law shall be to use reasonable efforts to assist
         the Fund with respect to any claim for exemption or refund under the
         tax law of jurisdictions for which the Fund has provided such
         information.

4.       Payments for Sales or Repurchases or Redemptions of Shares of the Fund

         The Custodian shall receive from the distributor for the Shares or
from the Transfer Agent of the Fund and deposit into the account of the
appropriate Portfolio such payments as are received for Shares of that
Portfolio issued or sold from time to time by the Fund. The Custodian will
provide timely notification to the Fund on behalf of each such Portfolio and
the Transfer Agent of any receipt by it of payments for Shares of such
Portfolio.

         From such funds as may be available for the purpose but subject to the
limitations of the Declaration of Trust and any applicable votes of the Board
of Trustees of the Fund pursuant thereto, the Custodian shall, upon receipt of
instructions from the Transfer Agent, make funds available for payment to
holders of Shares who have delivered to the Transfer Agent a request for
redemption or repurchase of their Shares. In connection with the redemption or
repurchase of Shares of a Portfolio, the Custodian is authorized upon receipt
of instructions from the Transfer Agent to wire funds to or through a
commercial bank designated by the redeeming shareholders. In connection with
the redemption or repurchase of Shares of the Fund, the Custodian shall honor
checks drawn on the Custodian by a holder of Shares, which checks have been
furnished by the Fund to the holder of Shares, when presented to the Custodian
in accordance with such procedures and controls as are mutually agreed upon
from time to time between the Fund and the Custodian.

5.       Proper Instructions

         Proper Instructions as used throughout this Contract means a writing
signed or initialed by one or more person or persons as the Board of Trustees
shall have from time to time authorized. Each such writing shall set forth the
specific transaction or type of transaction involved, including a specific
statement of the purpose for which such action is requested. Oral instructions
will be considered Proper Instructions if the Custodian reasonably believes
them to have been given by a person authorized to give such instructions with
respect to the transaction involved. The Fund shall cause all oral instructions
to be confirmed in writing. Proper Instructions may include communications
effected directly between electro-mechanical or electronic devices. For
purposes of this Section, Proper Instructions shall include instructions
received by the Custodian pursuant to any three-party agreement which requires
a segregated asset account in accordance with Section 2.12.

6.       Actions Permitted without Express Authority

         The Custodian may in its discretion, without express authority from
the Fund on behalf of each applicable Portfolio:

         1)       make payments to itself or others for minor expenses of
                  handling securities or other similar items relating to its
                  duties under this Contract, provided that all such payments
                  shall be accounted for to the Fund on behalf of the
                  Portfolio;

         2)       surrender securities in temporary form for securities in
                  definitive form;

         3)       endorse for collection, in the name of the Fund on behalf of
                  the Portfolio, checks, drafts and other negotiable
                  instruments; and

         4)       in general, attend to all non-discretionary details in
                  connection with the sale, exchange, substitution, purchase,
                  transfer and other dealings with the securities and property
                  of the Fund on behalf of the Portfolio except as otherwise
                  directed by the Board of Trustees of the Fund.

7.       Evidence of Authority

         The Custodian shall be protected in acting upon any instructions,
notice, request, consent, certificate or other instrument or paper believed by
it to be genuine and to have been properly executed by or on behalf of the
Fund. The Custodian may receive and accept a certified copy of a vote of the
Board of Trustees of the Fund as conclusive evidence (a) of the authority of
any person to act in accordance with such vote or (b) of any determination or
of any action by the Board of Trustees pursuant to the Declaration of Trust as
described in such vote, and such vote may be considered as in full force and
effect until receipt by the Custodian of written notice to the contrary.

8.       Duties of Custodian with Respect to the Books of Account and
         Calculation of Net Asset Value and Net Income

         The Custodian shall cooperate with and supply necessary information to
the entity or entities appointed by the Board of Trustees of the Fund to keep
the books of account of each Portfolio and/or compute the net asset value per
Share of the outstanding Shares of each Portfolio or, if directed in writing to
do so by the Fund on behalf of the Portfolio, shall itself keep such books of
account and/or compute such net asset value per Share. If so directed, the
Custodian shall also calculate daily the net income of the Portfolio as
described in the Fund's currently effective prospectus related to such
Portfolio and shall advise the Fund and the Transfer Agent daily of the total
amounts of such net income and, if instructed in writing by an officer of the
Fund to do so, shall advise the Transfer Agent periodically of the division of
such net income among its various components. The Fund acknowledges and agrees
that, with respect to investments maintained with the Underlying Transfer
Agent, the Underlying Transfer Agent is the sole source of information on the
number of shares of an Underlying Portfolio held by it on behalf of a Lifestyle
Portfolio and that the Custodian has the right to rely on holdings information
furnished by the Underlying Transfer Agent to the Custodian in performing its
duties under this Contract, including without limitation, the duties set forth
in this Section 8 and in Section 9 hereof; provided, however, that the
Custodian shall be obligated to reconcile information as to purchases and sales
of Underlying Shares contained in trade instructions and confirmations received
by the Custodian and to report promptly any discrepancies to the Underlying
Transfer Agent. The calculations of the net asset value per Share and the daily
income of each Portfolio shall be made at the time or times described from time
to time in the Fund's currently effective prospectus related to such Portfolio.

9.       Records

         The Custodian shall with respect to each Portfolio create and maintain
all records relating to its activities and obligations under this Contract in
such manner as will meet the obligations of the Fund under the Investment
Company Act of 1940, with particular attention to Section 31 thereof and Rules
31a-1 and 31a-2 thereunder. All such records shall be the property of the Fund
and shall at all times during the regular business hours of the Custodian be
open for inspection by duly authorized officers, employees or agents of the
Fund and employees and agents of the Securities and Exchange Commission. The
Custodian shall, at the Fund's request, supply the Fund with a tabulation of
securities owned by each Portfolio and held by the Custodian and shall, when
requested to do so by the Fund and for such compensation as shall be agreed
upon between the Fund and the Custodian, include certificate numbers in such
tabulations.

10.      Opinion of Fund's Independent Accountant

         The Custodian shall take all reasonable action, as the Fund on behalf
of each applicable Portfolio may from time to time request, to obtain from year
to year favorable opinions from the Fund's independent accountants with respect
to its activities hereunder in connection with the preparation of the Fund's
Form N-1A, and Form N-SAR or other annual reports to the Securities and
Exchange Commission and with respect to any other requirements of such
Commission.

<PAGE>   18

11.      Reports to Fund by Independent Public Accountants

         The Custodian shall provide the Fund, on behalf of each of the
Portfolios at such times as the Fund may reasonably require, with reports by
independent public accountants on the accounting system, internal accounting
control and procedures for safeguarding securities, futures contracts and
options on futures contracts, including securities deposited and/or maintained
in a Securities System, relating to the services provided by the Custodian
under this Contract; such reports, shall be of sufficient scope and in
sufficient detail, as may reasonably be required by the Fund to provide
reasonable assurance that any material inadequacies would be disclosed by such
examination, and, if there are no such inadequacies, the reports shall so
state.





12.      Rights of Inspection

         The Custodian shall allow the inspection of the Fund's securities, at
any time as may be requested by the Fund's Independent Public Accountants
pursuant to Rule 17f-2 under the 1940 Act.

13.      Compensation of Custodian

         The Custodian shall be entitled to reasonable compensation for its
services and expenses as Custodian as provided in Schedule B, as agreed upon
from time to time between the Fund on behalf of each applicable Portfolio and
the Custodian.

14.      Responsibility of Custodian

         So long as and to the extent that it is in the exercise of reasonable
care, the Custodian shall not be responsible for the title, validity or
genuineness of any property or evidence of title thereto received by it or
delivered by it pursuant to this Contract and shall be held harmless in acting
upon any notice, request, consent, certificate or other instrument reasonably
believed by it to be genuine and to be signed by the proper party or parties,
including any futures commission merchant acting pursuant to the terms of a
three-party futures or options agreement. The Custodian shall be held to the
exercise of reasonable care in carrying out the provisions of this Contract,
but shall be kept indemnified by and shall be without liability to the Fund for
any action taken or omitted by it in good faith without negligence. It shall be
entitled to rely on and may act upon advice of counsel (who may be counsel for
the Fund) on all matters, and shall be without liability for any action
reasonably taken or omitted pursuant to such advice.

         Except as may arise from the Custodian's own negligence or willful
misconduct or the negligence or willful misconduct of a sub-custodian or agent,
the Custodian shall be without liability to the Fund for any loss, liability,
claim or expense resulting from or caused by; (i) events or circumstances
beyond the reasonable control of the Custodian or any sub-custodian or
Securities



                                      18.

System or any agent or nominee of any of the foregoing, including, without
limitation, nationalization or expropriation, imposition of currency controls
or restrictions, the interruption, suspension or restriction of trading on or
the closure of any securities market, power or other mechanical or
technological failures or interruptions, computer viruses or communications
disruptions, acts of war or terrorism, riots, revolutions, work stoppages,
natural disasters or other similar events or acts; (ii) errors by the Fund or
the Investment Advisor in their instructions to the Custodian provided such
instructions have been in accordance with this Contract; (iii) the insolvency
of or acts or omissions by a Securities System; (iv) any delay or failure of
any broker, agent or intermediary, central bank or other commercially prevalent
payment or clearing system to deliver to the Custodian's sub-custodian or agent
securities purchased or in the remittance or payment made in connection with
securities sold; (v) any delay or failure of any company, corporation, or other
body in charge of registering or transferring securities in the name of the
Custodian, the Fund, the Custodian's sub-custodians, nominees or agents or any
consequential losses arising out of such delay or failure to transfer such
securities including non-receipt of bonus, dividends and rights and other
accretions or benefits; (vi) delays or inability to perform its duties due to
any disorder in market infrastructure with respect to any particular security
or Securities System; and (vii) any provision of any present or future law or
regulation or order of the United States of America, or any state thereof, or
any other country, or political subdivision thereof or of any court of
competent jurisdiction.

         The Custodian shall be liable for the acts or omissions of a foreign
banking institution to the same extent as set forth with respect to
sub-custodians generally in this Contract.

         If the Fund on behalf of a Portfolio requires the Custodian to take
any action with respect to securities, which action involves the payment of
money or which action may, in the opinion of the Custodian, result in the
Custodian or its nominee assigned to the Fund or the Portfolio being liable for
the payment of money or incurring liability of some other form, the Fund on
behalf of the Portfolio, as a prerequisite to requiring the Custodian to take
such action, shall provide indemnity to the Custodian in an amount and form
satisfactory to it.

         If the Fund requires the Custodian, its affiliates, subsidiaries or
agents, to advance cash or securities for any purpose (including but not
limited to securities settlements, foreign exchange contracts and assumed
settlement) or in the event that the Custodian or its nominee shall incur or be
assessed any taxes, charges, expenses, assessments, claims or liabilities in
connection with the performance of this Contract, except such as may arise from
its or its nominee's own negligent action, negligent failure to act or willful
misconduct, any property at any time held for the account of the applicable
Portfolio shall be security therefor and should the Fund fail to repay the
Custodian promptly, the Custodian shall be entitled to utilize available cash
and to dispose of such Portfolio's assets to the extent necessary to obtain
reimbursement.

         In no event shall the Custodian be liable for indirect, special or
consequential damages.

15.      Effective Period, Termination and Amendment

         This Contract shall become effective as of its execution, shall
continue in full force and effect until terminated as hereinafter provided, may
be amended at any time by mutual agreement of the parties hereto and may be
terminated by either party by an instrument in writing delivered or mailed,
postage prepaid to the other party, such termination to take effect not sooner
than thirty (30) days after the date of such delivery or mailing; provided,
however, that the Fund shall not amend or terminate this Contract in
contravention of any applicable federal or state regulations, or any provision
of the Declaration of Trust, and further provided, that the Fund on behalf of
one or more of the Portfolios may at any time by action of its Board of
Trustees (i) substitute another bank or trust company for the Custodian by
giving notice as described above to the Custodian, or (ii) immediately
terminate this Contract in the event of the appointment of a conservator or
receiver for the Custodian by the Comptroller of the Currency or upon the
happening of a like event at the direction of an appropriate regulatory agency
or court of competent jurisdiction.

         Upon termination of the Contract, the Fund on behalf of each
applicable Portfolio shall pay to the Custodian such compensation as may be due
as of the date of such termination and shall likewise reimburse the Custodian
for its costs, expenses and disbursements.

17.      Successor Custodian

         If a successor custodian for the Fund, of one or more of the
Portfolios shall be appointed by the Board of Trustees of the Fund, the
Custodian shall, upon termination, deliver to such successor custodian at the
office of the Custodian, duly endorsed and in the form for transfer, all
securities and other assets of each applicable Portfolio then held by it
hereunder and shall transfer to an account of the successor custodian all of
the securities and other assets of each such Portfolio held in a Securities
System or at the Underlying Transfer Agent.

         If no such successor custodian shall be appointed, the Custodian
shall, in like manner, upon receipt of a certified copy of a vote of the Board
of Trustees of the Fund, deliver at the office of the Custodian and transfer
such securities, funds and other properties in accordance with such vote.

         In the event that no written order designating a successor custodian
or certified copy of a vote of the Board of Trustees shall have been delivered
to the Custodian on or before the date when such termination shall become
effective, then the Custodian shall have the right to deliver to a bank or
trust company, which is a "bank" as defined in the Investment Company Act of
1940, doing business in Boston, Massachusetts, of its own selection, having an
aggregate capital, surplus, and undivided profits, as shown by its last
published report, of not less than $25,000,000, all securities, funds and other
properties held by the Custodian on behalf of each applicable Portfolio and all
instruments held by the Custodian relative thereto and all other property held
by it under this Contract on behalf of each applicable Portfolio and to
transfer to an account of such successor custodian all of the securities of
each such Portfolio held in any Securities System or at the Underlying Transfer
Agent. Thereafter, such bank or trust company shall be the successor of the
Custodian under this Contract.

         In the event that securities, funds and other properties remain in the
possession of the Custodian after the date of termination hereof owing to
failure of the Fund to procure the certified copy of the vote referred to or of
the Board of Trustees to appoint a successor custodian, the Custodian shall be
entitled to fair compensation for its services during such period as the
Custodian retains possession of such securities, funds and other properties and

24.      Shareholder Communications Election

         Securities and Exchange Commission Rule 14b-2 requires banks which
hold securities for the account of customers to respond to requests by issuers
of securities for the names, addresses and holdings of beneficial owners of
securities of that issuer held by the bank unless the beneficial owner has
expressly objected to disclosure of this information. In order to comply with
the rule, the Custodian needs the Fund to indicate whether it authorizes the
Custodian to provide the Fund's name, address, and share position to requesting
companies whose securities the Fund owns. If the Fund tells the Custodian "no",
the Custodian will not provide this information to requesting companies. If the
Fund tells the Custodian "yes" or does not check either "yes" or "no" below,
the Custodian is required by the rule to treat the Fund as consenting to
disclosure of this information for all securities owned by the Fund or any
funds or accounts established by the Fund. For the Fund's protection, the Rule
prohibits the requesting company from using the Fund's name and address for any
purpose other than corporate communications. Please indicate below whether the
Fund consents or objects by checking one of the alternatives below.


         YES [ ]  The Custodian is authorized to release the Fund's name,
                  address, and share positions.

         NO  [X]  The Custodian is not authorized to release the Fund's name,
                  address, and share positions.

25.      Miscellaneous Provision

         The execution of this Contract has been authorized by the Fund's
Trustees and by the sole shareholder. This Contract is executed on behalf of
the Fund or the Trustees of the Fund as Trustees and not individually and that
the obligations of this Contract are not binding upon any of the Trustees,
officers or shareholders of the Fund individually, but are 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 the State of Delaware.

                   SECURITIES LENDING AUTHORIZATION AGREEMENT

         Agreement dated the 26th day of August, 1998 between AMERICAN GENERAL
SERIES PORTFOLIO COMPANY 3, a registered management investment company
organized and existing under the laws of ----------- (the "Client"), and STATE
STREET BANK AND TRUST COMPANY, its affiliates or subsidiaries ("State Street"),
setting forth the terms and conditions under which State Street is authorized
to act on behalf of the Client with respect to the lending of certain
securities of the Client held by State Street as trustee, agent or custodian.

         NOW, THEREFORE, in consideration of the mutual promises and of the
mutual covenants contained herein, each of the parties does hereby covenant and
agree as follows:

1.       Definitions.  For the purposes hereof:

         (a) "Available Securities" means the securities of the Client that are
available for Loans pursuant to Section 3.

         (b) "Borrower" means any of the entities to which Available Securities
may be loaned under a Securities Loan Agreement, as described in Section 4.

         (c) "Collateral" means collateral delivered by a Borrower to secure
its obligations under a Securities Loan Agreement.

         (d) "Investment Manager" when used in any provision, means the person
or entity who has discretionary authority over the investment of the Available
Securities to which the provision applies.

         (e) "Loan" means a loan of Available Securities to a Borrower.

         (f) "Loaned Security" shall mean any "security" which is delivered as
a Loan under a Securities Loan Agreement; provided that, if any new or
different security shall be exchanged for any Loaned Security by
recapitalization, merger, consolidation, or other corporate action, such new or
different security shall, effective upon such exchange, be deemed to become a
Loaned Security in substitution for the former Loaned Security for which such
exchange was made.

         (g) "Market Value" of a security means the market value of such
security (including, in the case of a Loaned Security that is a debt security,
the accrued interest on such security) as determined by the independent pricing
service designated by State Street, or such other independent sources as may be
selected by State Street on a reasonable basis.



                                       1
<PAGE>   5

         (h) "Securities Loan Agreement" means the agreement between a Borrower
and State Street (on behalf of the Client) that governs Loans, as described in
Section 5.

         (i) "Replacement Securities" means securities of the same issuer,
class and denomination as Loaned Securities.

2.       Appointment of State Street.

         The Client hereby appoints and authorizes State Street, its affiliates
or subsidiaries, as its agent to lend Available Securities to Borrowers in
accordance with the terms of this Agreement. State Street shall have the
responsibility and authority to do or cause to be done all acts State Street
shall determine to be desirable, necessary, or appropriate to implement and
administer this securities lending program. The Client agrees that State Street
is acting as a fully disclosed agent and not as principal in connection with
the securities lending program. State Street may take action as agent of the
Client on an undisclosed or a disclosed basis. State Street is also hereby
authorized to request a third party bank to undertake certain custodial
functions in connection with holding of the Collateral provided by a Borrower
pursuant to the terms hereof. In connection therewith, State Street may
instruct said third party to establish and maintain a Borrower's account and a
State Street account wherein all Collateral, including cash shall be maintained
by said third party in accordance with the terms of a form of custodial
arrangement which shall also be consistent with the terms hereof.

3.       Securities to be Loaned.

         State Street acts or will act as agent, trustee or custodian of
certain securities owned by the Client. All of the Client's securities held by
State Street as agent, trustee or custodian shall be subject to this securities
lending program and constitute Available Securities hereunder, except those
securities which the Client or the Investment Manager specifically identifies
in notices to State Street as not being Available Securities. In the absence of
any such notice identifying specific securities, State Street shall have no
authority or responsibility for determining whether any of the Client's
securities should be excluded from the lending program.

4.       Borrowers.

         The Available Securities may be loaned to any Borrower identified on
the Schedule of Borrowers, as such Schedule may be modified from time to time
by State Street and Client, including without limitation, the Financial Markets
Group of State Street; provided, however, if Available Securities are loaned to
the Financial Markets Group, in addition to being consistent with the terms
hereof, said Loan shall be made in accordance with the terms of the Securities
Loan Agreement attached hereto as Exhibit 4.1, as modified form time to time in
accordance with the provisions hereof (hereinafter, the "State Street
Securities Loan



                                       2
<PAGE>   6

Agreement"). The form of the State Street Securities Loan Agreement may be
modified by State Street from time to time, without the consent of the Client,
in order to comply with the requirements of law or any regulatory authority
having jurisdiction over State Street, the Client or the securities lending
program or in any other manner that is not material and adverse to the
interests of the Client.

         The Client acknowledges that it is aware that State Street, acting as
"Lender's Agent" hereunder and thereunder, is or may be deemed to be the same
legal entity as State Street acting as "Borrower" under the State Street
Securities Loan Agreement, notwithstanding the different designations used
herein and therein or the dual roles assumed by State Street hereunder and
thereunder. Client represents that the power granted herein to State Street, as
agent, to lend U.S. Securities owned by Client (including, in legal effect, the
power granted to State Street to make Loans to itself) and the other powers
granted to State Street, as agent herein, are given expressly for the purpose
of averting and waiving any prohibitions upon such lending or other exercise of
such powers which might exist in the absence of such powers, and that
transactions effected pursuant to and in compliance with this Agreement and the
State Street Securities Loan Agreement will not constitute a breach of trust or
other fiduciary duty by State Street.

         The Client further acknowledges that it has granted State Street the
power to effect securities lending transactions with the Financial Markets
Group of State Street and other powers assigned to State Street hereunder and
under the Securities Loan Agreements and the State Street Securities Loan
Agreement as a result of the Client's desire to increase the opportunity for it
to lend securities held in its account on fair and reasonable terms to
qualified Borrowers without such loans being considered a breach of State
Street's fiduciary duty. In connection therewith, each party hereby agrees that
it shall furnish to the other party, upon request (i) the most recent available
audited statement of its financial condition, and (ii) the most recent
available unaudited statement of its financial condition, if more recent than
the audited statement. As long as any Loan is outstanding under this Agreement,
each party shall also promptly deliver to the other party all such financial
information that is subsequently available, and any other financial information
or statements that such other party may reasonably request.

         In the event any such Loan is made to the Financial Markets Group,
State Street hereby covenants and agrees for the benefit of the Clients that it
has adopted and implemented procedural safeguards to help ensure that all
actions taken by it hereunder will be effected by individuals other than, and
not under the supervision of, individuals who are acting in a capacity as
Borrower thereunder, and that all trades effected hereunder will take place at
the same fully negotiated "arms length" prices offered to similarly situated
third parties by State Street when it acts as lending agent, notwithstanding
the inherent conflict of interest with respect to Loans to be effected by State
Street to the Financial Markets Group.



                                       3
<PAGE>   7

         In the event the Client approves lending to borrowers resident in the
United Kingdom, the Client shall complete Part 1 of the document known as a
"MOD-2 form," which is attached hereto as Exhibit 4.2.

         In the event that securities lending activity is undertaken through
its London office, State Street becomes subject to additional regulation in the
UK, and State Street is obliged to notify the you of the following matters:

         i.       State Street shall make available to you established
                  procedures in accordance with the requirements of the
                  Securities and Futures Authority for the effective
                  consideration of complaints concerning State Street's
                  activities carried on in the UK.

         ii.      Where a liability in one currency is to be matched by an
                  asset in a different currency, or where an investment
                  transaction relates to an investment denominated in a
                  currency other than sterling, a movement of exchange rates
                  may have a separate effect, favorable or unfavorable, on the
                  gain or loss which would otherwise be experienced on the
                  investment.

         iii.     State Street or an affiliate may have an interest that is
                  material to the investment or transaction concerned and
                  neither State Street nor any such affiliate shall be obliged
                  to disclose such interest or account to you for any profits
                  or benefits made or derived by it or any of its associates
                  from any such transaction.

         iv.      Any assets which State Street holds in the form of money
                  shall not be treated by State Street as the Clients' Money as
                  defined by The Financial Services (Client Money) Regulations
                  1991 of the United Kingdom as amended (the "Clients' Money
                  Regulations") and will not be held in accordance with the
                  Clients' Money Regulations or such other regulations as shall
                  amend or replace the Clients' Money Regulations from time to
                  time.

5.       Securities Loan Agreements.

         The Client authorizes State Street to enter into one or more
Securities Loan Agreements with such Borrowers as may be selected by State
Street. Each Securities Loan Agreement shall have such terms and conditions as
State Street may negotiate with the Borrower, however certain terms of
individual loans, including rebate fees to be paid to the Borrower for the use
of cash Collateral, shall be negotiated at the time a loan is made.



                                       4
<PAGE>   8

6.       Loans of Available Securities.

         State Street shall have authority to make Loans of Available
Securities to Borrowers, and to deliver such securities to Borrowers. State
Street shall be responsible for determining whether any such Loan shall be
made, and for negotiating and establishing the terms of each such Loan. State
Street shall have the authority to terminate any Loan in its discretion, at any
time and without prior notice to the Client.

         The Client acknowledges that State Street administers securities
lending programs for other clients of State Street. State Street will allocate
securities lending opportunities among its clients, using reasonable and
equitable methods established by State Street from time to time. State Street
does not represent or warrant that any amount or percentage of the Client's
Available Securities will in fact be loaned to Borrowers. The Client agrees
that it shall have no claim against State Street and State Street shall have no
liability arising from, based on, or relating to, loans made for other clients,
or loan opportunities refused hereunder, whether or not State Street has made
fewer or more loans for any other client, and whether or not any loan for
another client, or the opportunity refused, could have resulted in loans made
under this Agreement.

         The Client also acknowledges that, under the applicable Securities
Loan Agreements, the Borrowers will not be required to return Loaned Securities
immediately upon receipt of notice from State Street terminating the applicable
Loan, but instead will be required to return such Loaned Securities within such
period of time following such notice as is specified in the applicable
Securities Loan Agreement. Upon receiving a notice from the Client or the
Investment Manager that Available Securities which have been loaned to a
Borrower should no longer be considered Available Securities (whether because
of the sale of such securities or otherwise), State Street shall use its
reasonable efforts to notify promptly thereafter the Borrower which has
borrowed such securities that the Loan of such securities is terminated and
that such securities are to be returned within the time specified by the
applicable Securities Loan Agreement.

7. Distributions on and Voting Rights with Respect to Loaned Securities.

         The Client represents and warrants that it is the beneficial owner of
(or exercises complete investment discretion over) all Available Securities
free and clear of all liens, claims, security interests and encumbrances and no
such security has been sold, and that it is entitled to receive all
distributions made by the issuer with respect to Loaned Securities. Except as
provided in the next sentence, all interest, dividends, and other distributions
paid with respect to Loaned Securities shall be credited to the Client's
account on the date such amounts are delivered by the Borrower to State Street.
Any non-cash distribution on Loaned Securities which is in the nature of a
stock split or a stock dividend shall be added to the Loan (and shall be
considered to constitute Loaned Securities) as of the date such non-cash



                                       5
<PAGE>   9

distribution is received by the Borrower; provided that the Client (or
Investment Manager) may, by giving State Street ten (l0) business days' notice
prior to the date of such non-cash distribution, direct State Street to request
that the Borrower deliver such non-cash distribution to State Street, pursuant
to the applicable Securities Loan Agreement, in which case State Street shall
credit such non-cash distribution to the Client's account on the date it is
delivered to State Street.

         The Client acknowledges that it will not be entitled to participate in
any dividend reinvestment program or to vote with respect to securities that
are on loan on the applicable record date for such securities.

         The Client also acknowledges that any payments of distributions from
Borrower to the Client are in substitution for the interest or dividend accrued
or paid in respect of Loaned Securities and that the tax treatment of such
payment may differ from the tax treatment of such interest or dividend.

         If an installment, call or rights issue becomes payable on or in
respect of any Loaned Securities, State Street shall use all reasonable
endeavors to ensure that any timely instructions from the Client are complied
with, but State Street shall not be required to make any payment unless the
Client has first placed it in funds to make such payment.

8.       Collateral.

         (a) Receipt of Collateral. The Client authorizes State Street, or a
third party bank, to receive and to hold, on the Client's behalf, Collateral
from Borrowers to secure the obligations of Borrowers with respect to any loan
of securities made on behalf of the Client pursuant to the Securities Loan
Agreements. All investments of cash Collateral shall be for the account and at
the risk of the Client. Concurrently with the delivery of the Loaned Securities
to the Borrower under any Loan, State Street shall receive from the Borrower
Collateral in any of the forms listed on Schedule 8.1. Said Schedule may be
amended from time to time by State Street upon written notice to the Client.
With respect to foreign cash Collateral, State Street will provide the Client
with a multicurrency investment vehicle through which the foreign cash will be
converted to U.S. dollars and invested pursuant to Section 9 hereof ("MCIV").
The Client acknowledges that State Street, in providing MCIV, may receive
additional compensation by managing its interest rate exposure.

         Collateral shall have a Market Value of not less than one hundred
percent (l00%) of the Market Value of the Loaned Securities. Thereafter, State
Street shall take such action as is appropriate with respect to the Collateral
under the applicable Securities Loan Agreement.

         (b) Marking to Market. State Street shall value all Loaned Securities
in accordance with its customary practice.



                                       6
<PAGE>   10

         (c) Return of Collateral. The Collateral shall be returned to Borrower
at the termination of the Loan upon the return of the Loaned Securities by
Borrower to State Street in accordance with the applicable Securities Loan
Agreement.

         (d) Limitations. State Street shall invest cash Collateral in
accordance with any directions, including any limitations established by the
Client in a writing identified to this Agreement and acknowledged in writing by
State Street and shall exercise reasonable care, skill, diligence and prudence
in the investment of Collateral. Subject to the foregoing limits and standard
of care, State Street does not assume any market or investment risk of loss
with respect to the currency conversions associated with the use of MCIV or the
investment of cash Collateral. If the value of the cash Collateral so invested
is insufficient to return the rebate fee (i.e., the return to the Borrower for
use of cash Collateral), the full amount of the Collateral (U.S. dollar or
otherwise), or any and all other amounts due to such Borrower pursuant to the
Securities Loan Agreement, the Client shall be solely responsible for such
shortfall and State Street may debit the Client's account. In addition, State
Street shall be entitled to charge the Client's accounts for such shortfall in
accordance with Section 9.

9.       Investment of Cash Collateral and Compensation.

         To the extent that a Loan is secured by cash Collateral, such cash
Collateral, including money received with respect to the investment of the
same, or upon the maturity, sale, or liquidation of any such investments, shall
be invested by State Street, subject to the directions referred to above, if
any, in short-term instruments, short term investment funds maintained by State
Street, money market mutual funds and such other investments as State Street
may from time to time select, including without limitation investments in
obligations or other securities of State Street or of any State Street
affiliate and investments in any short-term investment fund, mutual fund,
securities lending trust or other collective investment fund with respect to
which State Street and/or its affiliates provide investment management or
advisory, trust, custody, transfer agency, shareholder servicing and/or other
services for which they are compensated.

         The Client acknowledges that interests in such mutual funds,
securities lending trusts and other collective investment funds, to which State
Street and/or one or more of its affiliates provide services are not guaranteed
or insured by State Street or any of its affiliates or by the Federal Deposit
Insurance Corporation or any government agency. The Client hereby authorizes
State Street to purchase or sell investments of cash Collateral to or from
other accounts held by State Street or its affiliates.

         The net income generated by any investment made pursuant to the
preceding paragraph of this Section 9 shall be allocated among the Borrower,
State Street, and the Client, as follows: (a) a portion of such income shall be
paid to the Borrower in accordance



                                       7
<PAGE>   11

with the agreement negotiated between the Borrower and State Street; (b) the
balance, if any, shall be split between State Street [as compensation for its
services in connection with this securities lending program and the Client [as
such income shall be credited to the Client's account], in accordance with the
fee schedule attached hereto as Schedule A.

         In the event the net income generated by any investment made pursuant
to the first paragraph of this Section 9 does not equal or exceed the amount
due the Borrower in accordance with the agreement between Borrower and State
Street, State Street shall debit the Client's account by an amount equal to the
difference between the net income generated and the amounts to be paid to the
Borrower pursuant to the Securities Loan Agreement. In the event debits to the
Client's account produce a deficit therein, State Street shall sell or
otherwise liquidate investments made with cash Collateral and credit the net
proceeds of such sale or liquidation to satisfy the deficit. In the event the
foregoing does not eliminate the deficit, State Street shall have the right to
charge the deficiency to any other account or accounts maintained by the Client
with State Street.

          In the event of a Loan to a Borrower resident in Canada, which is
made over record date for a dividend reinvestment program ("DRP") and is
secured by cash Collateral, the Borrower shall pay the Client a substitute
payment equal to the full amount of the cash dividend declared, and may pay a
loan premium, the amount of which shall be negotiated by State Street, above
the amount of the cash dividend. Such loan premium shall be allocated between
State Street and the Client as follows: (a) a portion of such loan premium
shall be paid to State Street as compensation for its services in connection
with this securities lending program, in accordance with Schedule A and (b) the
remainder of such loan premium shall be credited to the Client's account.

         To the extent that a Loan is secured by non-cash Collateral, the
Borrower shall be required to pay a loan premium, the amount of which shall be
negotiated by State Street. Such loan premium shall be allocated between State
Street and the Client as follows: (a) a portion of such loan premium shall be
paid to State Street as compensation for its services in connection with this
securities lending program, in accordance with Schedule A hereto; and (b) the
remainder of such loan premium shall be credited to the Client's account.

         The Client acknowledges that in the event that the Client's
participation in securities lending generates income for the Client, State
Street may be required to withhold tax or may claim such tax from the Client as
is appropriate in accordance with applicable law.

         The Client shall reimburse State Street for such reasonable fees and
expenses that State Street may incur in connection with the performance of its
obligations hereunder, including, without limitation: (i) the ordinary
telecommunication charges associated with the movement of securities in
connection with the securities lending activity contemplated by this Agreement;
and (ii) any and all funds advanced by State Street on behalf of the Client as



                                       8
<PAGE>   12

a consequence of the Client's obligations hereunder, including the Client's
obligation to return cash Collateral to the Borrower and to pay any fees due
the Borrower, all as provided in Section 8 hereof.

10.      Fee Disclosure.

         The fees associated with the investment of cash Collateral in funds
maintained or advised by State Street are disclosed on Schedule A hereto. Said
Schedule may be replaced from time to time by State Street upon notice to the
Client. An annual report with respect to such funds is available to the Client,
at no expense, upon request.

11.      Recordkeeping and Reports.

         State Street will establish and maintain such records as are
reasonably necessary to account for Loans that are made and the income derived
therefrom. On a monthly basis, State Street will provide the Client with a
statement describing the Loans made, and the income derived from the Loans,
during the period covered by such statement. Each party to this Agreement shall
comply with the reasonable requests of the other for information necessary to
the requester's performance of its duties in connection with this securities
lending program.

12.      Standard of Care

         Subject to the requirements of applicable law, State Street shall not
be liable for any loss or damage, including counsel fees and court costs,
whether or not resulting from their acts or omissions to act hereunder or
otherwise, unless the loss damage arises out of State Street's own gross
negligence. Except for any liability, loss, or expense arising from or
connected with State Street's own gross negligence, the Client agrees to
reimburse and hold State Street harmless from and against any liability, loss
and expense, including counsel fees and expenses and court costs, arising in
connection with any breach of any representation, covenant or agreement of the
Client contained in this Agreement or any Loan or arising from or connected
with claims of any third parties, including any Borrower, from and against all
taxes and other governmental charges, and from and against any out-of-pocket or
incidental expenses. State Street may charge any amounts to which it is
entitled hereunder against the Client's account. Without limiting the
generality of the foregoing, the Client agrees: (i) that State Street shall not
be responsible for any statements, representations or warranties which any
Borrower makes in connection with any securities loans hereunder, or for the
performance by any Borrower of the terms of a Loan, or any agreement related
thereto, and shall not be required to ascertain or inquire as to the
performance or observance of, or a default under the terms of, a Loan or any
agreement related thereto; (ii) that State Street shall be fully protected in
acting in accordance with the oral or written instructions of any person
believed by State Street to be authorized to execute this Agreement on behalf
of the Client



                                       9
<PAGE>   13

(an "Authorized Person"); (iii) that in the event of a default by a Borrower
under a Loan, State Street shall be fully protected in acting in its sole
discretion in a manner it deems appropriate; (iv) that State Street shall not
be under any duty or obligation to take action to effect payment by a Borrower
of any amounts owed by the Borrower pursuant to the Loan Agreement, provided
State Street timely advises the Client of the non-payment by the Borrower of
any such amount; and (v) that the records of State Street shall be presumed to
reflect accurately any oral instructions given by an Authorized Person or a
person believed by State Street to be an Authorized Person.

         The Client acknowledges that, when lending Gilt securities, there is
intraday settlement exposure from the Borrower's settlement bank. In
particular, Client has daily exposure that the Gilt collateral position backed
by the assured payment from the Borrower's settlement bank is unsecured.

         State Street, in determining the Market Value of Securities, including
without limitation, Collateral, may rely upon any recognized pricing service
and shall not be liable for any errors made by such service.

13.      Representations and Warranties.

         Each party hereto represents and warrants that (a) it has the power to
execute and deliver this Agreement, to enter into the transactions contemplated
hereby, and to perform its obligations hereunder; (b) it has taken all
necessary action to authorize such execution, delivery, and performance; (c)
this Agreement constitutes a legal, valid, and binding obligation enforceable
against it; and (d) the execution, delivery, and performance by it of this
Agreement will at all times comply with all applicable laws and regulations.

         The Client represents and warrants that (a) it has made its own
determination as to the tax treatment of any dividends, remuneration or other
funds received hereunder; and (b) the financial statements delivered to State
Street pursuant to Section 4 fairly present its financial condition and there
has been no material adverse change in its financial condition or the financial
condition of any parent company since the date of the balance sheet included
within such financial statements. Each Loan shall constitute a present
representation by the Client that there has been no material adverse change in
its financial condition or the financial condition of any parent company that
has not been disclosed in writing to State Street since the date of the most
recent financial statements furnished to State Street pursuant to Section 4.

         The person executing this Agreement on behalf of the Client represents
that he or she has the authority to execute this Agreement on behalf of the
Client.



                                      10
<PAGE>   14

         In the event that Client directs State Street to invest cash
Collateral in the State Street Global Securities Lending Trust, the Client also
represents and warrants to, and agrees and covenants with, State Street Global
Securities Lending Trust (the "Trust") and the Trustee of the Trust, as of the
date hereof and as of the date or dates on which any units of the Trust
("Units") are purchased (collectively, the "Date of Purchase") that:

                  (a)      The Units will be purchased for the account of the
                           Client for investment only and not with a view to,
                           or with any intention of, a distribution or resale
                           thereof, in whole or in part, or the grant of any
                           participation therein. The Client is aware of the
                           risks associated with an investment in the Trust and
                           has not received any form of general solicitation or
                           advertising in connection with its decision to
                           purchase Units.

                  (b)      The Client understands that the Trust will not be
                           registered under the Investment Company Act of 1940
                           (the "1940 Act") because the Trust will be qualified
                           as an excepted entity under Section 3(c)(7) of the
                           1940 Act. Pursuant to such exception the Trust will
                           be beneficially owned only by "qualified purchasers"
                           as defined in the 1940 Act and the rules and
                           regulations promulgated thereunder and by such other
                           persons as are otherwise entitled to participate in
                           an entity qualified under Section 3(c)(7) of the
                           1940 Act. Accordingly, the Client hereby represents
                           that as of the date hereof and as of the Date of
                           Purchase of the Units, the Client is either:

         [Please check and initial the appropriate box or boxes]

______            [ ]      a qualified institutional buyer as defined in
Initial of                 paragraph (a) of Rule 144A (the "Rule") of the Act,
Authorized                 acting for its own account, the account of another
Signer                     qualified institutional buyer, or the account of a
                           qualified purchaser, and is not: (i) a dealer
                           described in paragraph (a)(1)(ii) of the Rule that
                           owns and invests on a discretionary basis less than
                           $25 million in securities of issuers that are not
                           affiliated persons of the dealer; or (ii) a plan
                           referred to in paragraph (a)(1)(D) or (a)(1)(E) of
                           the Rule, or a trust fund referred to in paragraph
                           (a)(1)(F) of the Rule that holds the assets of such
                           a plan, if investment decisions with respect to the
                           plan are made by the beneficiaries of the plan; or

______            [ ]      an entity that in the aggregate owns and invests on
Initial of                 a discretionary basis $25 million or more in
Authorized                 Qualified Purchaser Investments (as defined in
Signer                     Exhibit A). In making this determination, the amount
                           of any outstanding indebtedness incurred to make the
                           Qualified Purchaser Investments held by the Client 
                           shall be subtracted from the Qualified Purchaser 
                           Investments.

<PAGE>   15

                  (c) No beneficiary or investor of the Client has any right to
consult with regard to, advise or direct the investments made by or on behalf
of the Client, and the Client has not been organized for the purpose of
purchasing Units.

                  (d) If the Client: is (A) classified as a partnership for
federal income tax purposes, (B) a "grantor trust," any portion of which is
treated as owned by the grantor(s) or other person(s) under sections 671-679 of
the Code, or (C) an "S corporation" within the meaning of section 1361(a) of
the Code (any of (A), (B), or (C), a "Flow-Through Entity"), the beneficial
owners of the Client which is a Flow-Through Entity are not investing in the
Trust through the Client for the principal purpose of avoiding the 100-partner
limitation in Treasury Regulations section.1.7704-1(h)(i)(ii).

                  (e) The execution and delivery of this Agreement by the
Client does not require any approval, authorization, license, or filing from or
with any foreign, federal, state or municipal board or agency on the part of
the Client or in connection with the offer and sale of the Units on the part of
the Trust or the Trustee or any of its affiliates.

                  (f) No provision of any applicable law, regulation or
document by which the Client is bound prohibits the purchase of Units in the
Trust by the Client.

                  (g) Simultaneously herewith the Client has completed,
executed and delivered to the Trust a Form W-8 setting forth certain taxpayer
identification information required by the Trust.

         The Client hereby represents to State Street that: (i) its policies
generally permit it to engage in securities lending transactions; (ii) its
policies permit it to purchase shares of the Navigator Securities Lending Trust
with cash Collateral; (iii) its participation in State Street's securities
lending program, including the investment of cash Collateral in the Navigator
Securities Lending Trust, and the existing series thereof has been approved by
a majority of the directors or trustees which directors and trustees are not
"interested persons" within the meaning of section 2(a)(19) of the Investment
Company Act of 1940, and such directors or trustees will evaluate the
securities lending program no less frequently than annually to determine that
the investment of cash Collateral in the Navigator Securities Lending Trust,
including any series thereof, is in the Client's best interest; and (iv) its
prospectus provides appropriate disclosure concerning its securities lending
activity.

         The Client hereby further represents that it is not subject to the
Employee Retirement Income Security Act of 1974, as amended ("ERISA") with
respect to this Agreement and the Securities; that it qualifies as an
"accredited investor" within the meaning of Rule 501 of



                                      12
<PAGE>   16

Regulation D under the Securities Act of 1933, as amended; and that the
taxpayer identification number(s) and corresponding tax year-end are as set
forth on Schedule B.

14.      Indemnification.

         (a) If at the time of a default by a Borrower with respect to a Loan
(within the meaning of the applicable Securities Loan Agreement) some or all of
the Loaned Securities under such Loan have not been returned by the Borrower,
and subject to the terms of this Agreement, State Street shall indemnify the
Client against the failure of the Borrower as follows. State Street shall
purchase a number of Replacement Securities equal to the number of such
unreturned Loaned Securities, to the extent that such Replacement Securities
are available on the open market. Such Replacement Securities shall be
purchased by applying the proceeds of the Collateral with respect to such Loan
to the purchase of such Replacement Securities. Subject to the Client's
obligations pursuant to Section 8 hereof, if and to the extent that such
proceeds are insufficient or the Collateral is unavailable, the purchase of
such Replacement Securities shall be made at State Street's expense.

         (b) If State Street is unable to purchase Replacement Securities
pursuant to Paragraph (a) hereof, State Street shall credit to the Client's
account an amount equal to the Market Value of the unreturned Loaned Securities
for which replacement securities are not so purchased, determined as of (i) the
last day the Collateral continues to be successfully marked to market against
the unreturned Loaned Securities; or (ii) the next business day following the
day referred to in (i) above, if higher.

         (c) In addition to making the purchases or credits required by
Paragraphs (a) and (b) hereof, State Street shall credit to the Client's
account the value of all distributions on the Loaned Securities (not otherwise
credited to the Client's accounts with State Street), the record dates for
which occur before the date that State Street purchases Replacement Securities
pursuant to Paragraph (a) or credits the Client's account pursuant to Paragraph
(b).

         (d) Any credits required under Paragraphs (b) and (c) hereof shall be
made by application of the proceeds of the Collateral (if any) that remains
after the purchase of Replacement Securities pursuant to Paragraph (a). If and
to the extent that the Collateral is unavailable or the value of the proceeds
of the remaining Collateral is less than the value of the sum of the credits
required to be made under Paragraphs (b) and (c), such credits shall be made at
State Street's expense.

         (e) If after application of Paragraphs (a) through (d) hereof,
additional Collateral remains or any previously unavailable Collateral becomes
available or any additional amounts owed by the Borrower with respect to such
Loan are received from the Borrower, State Street shall apply the proceeds of
such Collateral or such additional amounts first to reimburse itself for any
amounts expended by State Street pursuant to Paragraphs (a) through



                                      13
<PAGE>   17

(d) above, and then to credit to the Client's account all other amounts owed by
the Borrower to the Client with respect to such Loan under the applicable
Securities Loan Agreement.

         (f) In the event that State Street is required to make any payment
and/or incur any loss or expense under this Section, State Street shall, to the
extent of such payment, loss, or expense, be subrogated to, and succeed to, all
of the rights of the Client against the Borrower under the applicable
Securities Loan Agreement.

         (g) The provisions of this Section 14 shall not apply to losses
attributable to war, riot, revolution, acts of government or other causes
beyond the reasonable control or apprehension of State Street.

15.      Continuing Agreement and Termination.

         It is the intention of the parties hereto that this Agreement shall
constitute a continuing agreement in every respect and shall apply to each and
every Loan, whether now existing or hereafter made. The Client and State Street
may each at any time terminate this Agreement upon five (5) business days'
written notice to the other to that effect. The only effects of any such
termination of this Agreement will be that (a) following such termination, no
further Loans shall be made hereunder by State Street on behalf of the Client,
and (b) State Street shall, within a reasonable time after termination of this
Agreement, terminate any and all outstanding Loans. The provisions hereof shall
continue in full force and effect in all other respects until all Loans have
been terminated and all obligations satisfied as herein provided.

16.      Notices.

         Except as otherwise specifically provided herein, notices under this
Agreement may be made orally, in writing, or by any other means mutually
acceptable to the parties. If in writing, a notice shall be sufficient if
delivered to the party entitled to receive such notices at the following
addresses:

         If to Client:

                  [insert name and address]


         If to State Street:

<PAGE>   18

or to such other addresses as either party may furnish the other party by
written notice under this section.

         Whenever this Agreement permits or requires the Client to give notice
to, direct, provide information to State Street, such notice, direction, or
information shall be provided to State Street on the Client's behalf by any
individual designated for such purpose by the Client in a written notice to
State Street. (This Agreement shall be considered such a designation of the
person executing the Agreement on the Client's behalf.) After its receipt of
such a notice of designation, and until its receipt of a notice revoking such
designation, State Street shall be fully protected in relying upon the notices,
directions, and information given by such designee.

17.      Miscellaneous.

         This Agreement supersedes any other agreement between the parties or
any representations made by one party to the other, whether oral or in writing,
concerning loans of securities by State Street on behalf of the Client. This
Agreement may be assigned by State Street without the prior written consent of
the other party. Subject to the foregoing, this Agreement shall be binding upon
and shall inure to the benefit of the parties hereto and their respective heirs,
representatives, successors, and assigns. This Agreement shall be governed and
construed in accordance with the laws of the Commonwealth of Massachusetts. The
Client hereby irrevocably submits to the jurisdiction of any Massachusetts state
or Federal court sitting in The Commonwealth of Massachusetts in any action or
proceeding arising out of or related to this Agreement and hereby irrevocably
agrees that all claims in respect of such action or proceeding may be heard and
determined in such Massachusetts state or Federal court except that this
provision shall not preclude any party from removing any action to Federal
court. The Client hereby irrevocably waives, to the fullest extent it may
effectively do so, the defense of an inconvenient forum to the maintenance of
such action or proceeding. Client hereby irrevocably appoints             as its
agent to receive on its behalf service of copies of the summons and complaint
and any other process which may be served in any such action or proceeding (the
"Process Agent"). Such service may be made by mailing or delivering a copy of
such process, in care of the Process Agent at the above address. The Client
hereby irrevocably authorizes and directs the Process Agent to accept such
service on its behalf. As an alternative method of service, the Client also
irrevocably consents to the service of any and all process in any such action or
proceeding by the mailing of copies of such process to the Client at its address
specified in Section       hereof. The Client agrees that a final judgment in
any such action or proceeding, all appeals having been taken or the time period
for such appeals having expired, shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law. The provisions of this Agreement are severable and the invalidity or
unenforceability of



                                      15
<PAGE>   19

any provision hereof shall not affect any other provision of this Agreement. If
in the construction of this Agreement any court should deem any provision to be
invalid because of scope or duration, then such court shall forthwith reduce
such scope or duration to that which is appropriate and enforce this Agreement
in its modified scope or duration.

         The execution of this Agreement has been authorized by the Client's
Trustees and by the sole shareholder. This Agreement is executed on behalf of
the Client or the Trustees of the Client 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 Client individually, but are binding
only upon the assets and property of the Client. A certificate of Trust in
respect of the Client is on file with the Secretary of the State of Delaware.

18.      Securities Investors Protection Act of 1970 Notice.

         CLIENT IS HEREBY ADVISED AND ACKNOWLEDGES THAT THE PROVISIONS OF THE
SECURITIES INVESTOR PROTECTION ACT OF 1970 MAY NOT PROTECT THE CLIENT WITH
RESPECT TO THE LOAN OF SECURITIES HEREUNDER AND THAT, THEREFORE, THE COLLATERAL
DELIVERED TO THE CLIENT MAY CONSTITUTE THE ONLY SOURCE OF SATISFACTION OF THE
BROKER'S OR DEALER'S OBLIGATION IN THE EVENT THE BROKER OR DEALER FAILS TO
RETURN THE SECURITIES.

19.      Counterparts.

         The Agreement may be executed in any number of counterparts, each of
which shall be deemed to be an original, but such counterparts shall, together,
constitute only one (1) instrument.

20.      Modification.

                                   EXHIBIT A


                        QUALIFIED PURCHASER INVESTMENTS


         This Exhibit is designed to assist the Client in determining which of
its assets are Qualified Purchaser Investments and the appropriate method of
valuing those assets. Although the definition of Qualified Purchaser
Investments includes most of what are ordinarily considered "investments" or
"securities" (but excludes assets such as jewelry, artwork, antiques and other
similar collectibles), issues may arise as to whether a particular holding
falls within the definition. The Client is encouraged to consult its legal
and/or investment advisors for guidance on these issues.

TYPES OF INVESTMENTS. The term "Qualified Purchaser Investment" includes the
investments described below.

(a)      Cash and cash equivalents (including foreign currency) held for
         investment purposes, including bank deposits, certificates of deposit,
         bankers acceptances, and the net cash surrender value of an insurance
         policy.

(b)      Securities such as

         (i)      shares of (and other interests in) mutual funds, closed-end
                  funds, hedge funds, and commodity pools;

         (ii)     securities, including common stock, preferred stock and other
                  equity instruments as well as bonds, notes, debentures and
                  other debt obligations, of public companies (including
                  companies listed on certain foreign exchanges);

         (iii)    securities, including common stock, preferred stock and other
                  equity instruments as well as bonds, notes, debentures and
                  other debt obligations, of private companies with at least
                  $50 million in shareholders' equity;

         (iv)     interests in family-owned or closely-held businesses
                  controlled by the Client if they fall in one of categories
                  (i)-(iii) above; and

         (v)      bonds, notes and similar debt obligations issued by federal,
                  state and local governments and agencies.

(c)      Real estate held for investment purposes (which does not include a
         place of business used by the Client or the Subscriber's family, or a
         personal residence used by the


<PAGE>   24

         Client or the Subscriber's family unless the residence is treated as
         an investment for tax purposes).

(d)      Commodity futures contracts, options on commodity futures contracts,
         and options on physical commodities traded on or subject to the rules
         of a major commodities exchange held for investment purposes.

(e)      Physical commodities such as gold or silver with respect to which a
         commodity interest is traded on or subject to the rules of a major
         commodities exchange held for investment purposes.

(f)      Financial contracts entered into for investment purposes including
         swaps and similar contracts.

VALUATION. A Qualified Purchaser Investment should be valued at its fair market
value as of the most recent practicable date or its cost, provided that
commodity interests should be valued at the initial margin or option premium
deposited in connection with such interests.

INVESTMENTS BY SUBSIDIARIES. The amount of Qualified Purchaser Investments
owned by an Entity other than a so-called "Family Company" may include
investments owned by majority-owned subsidiaries of the Entity and investments
owned by an Entity ("Parent Entity") of which the Entity is a majority-owned
subsidiary, or by a majority-owned subsidiary of the Entity and other
majority-owned subsidiaries of the Parent Entity.

         or transmission failure or damage, or other causes reasonably beyond
         its control, such party shall not be liable for damages to the other
         for any damages resulting from such failure to perform or otherwise
         from such causes.

    5.05 In no event and under no circumstances shall either party to this

the control and ownership of State Street (the "Data Access Services"); and

         WHEREAS, State Street makes available to the Customer certain Data
Access Services solely for the benefit of the Customer, and intends to provide
additional services, consistent with the terms and conditions of this Addendum.

         NOW, THEREFORE, in consideration of the mutual covenants and
agreements herein contained, and for other good and valuable consideration, the
parties agree as follows:

Instructions"), and (iii) access data for the purpose of reporting and analysis,
shall be deemed to be Data Access Services for purposes of this Addendum.

         c. Additional Services. State Street may from time to time agree to
make available to the Customer additional Systems that are not described in the
attachments to this Addendum. In the absence of any other written agreement

2.       NO USE OF THIRD PARTY SYSTEMS-LEVEL SOFTWARE

State Street, which agreement will not be unreasonably withheld. The Customer
may secure from State Street the right to access the System or the Data Access
Services through computer and telecommunications facilities or devices complying
with the Designated Configuration at additional locations only upon the prior
written consent of State Street and on terms to be mutually agreed upon by the
parties.

         e. Title. Title and all ownership and proprietary rights to the System,

Customer) after such discontinuance, assume responsibility to provide accounting
services under the terms of the Custodian Contract.

         h. Inspections. State Street shall have the right to inspect the use of
the System and the Data Access Services by the Customer and the Investment

unreasonable disruption of the Customer's or the Investment Advisor's business.

4.       PROPRIETARY INFORMATION

         a. Proprietary Information. The Customer acknowledges and State Street
represents that the System and the databases, computer programs, screen formats,

Street. Any and all such information provided by State Street to the Customer
shall be deemed proprietary and confidential information of State Street
(hereinafter "Proprietary Information"). The Customer agrees that it will hold
such Proprietary Information in the strictest confidence and secure and protect
it in a manner consistent with its own procedures for the protection of its own
confidential information and to take appropriate action by instruction or
agreement with its employees who are permitted access to the Proprietary
Information to satisfy its obligations hereunder. The Customer further
acknowledges that State Street shall not be required to provide the Investment
Advisor with access to the System unless it has first received from the
Investment Advisor an undertaking with respect to State Street's Proprietary
Information in the form of Attachment C to this Addendum. The Customer also
acknowledges that State Street shall not be required to provide Customer's
independent auditor with access to the System unless it has first received from
such independent auditor an undertaking with respect to State Street's
Proprietary Information in the form of Attachment C-1 to this Addendum. The
Customer shall use all commercially reasonable efforts to assist State Street
in identifying and preventing any unauthorized use, copying or disclosure of
the Proprietary Information or any portions thereof or any of the logic,
formats or designs contained therein.

         b. Cooperation. Without limitation of the foregoing, the Customer shall
advise State Street immediately in the event the Customer learns or has reason
to believe that any person to whom the Customer has given access to the
Proprietary Information, or any portion thereof, has violated or intends to
violate the terms of this Addendum, and the Customer will, at its expense,
co-operate with State Street in seeking injunctive or other equitable relief in
the name of the Customer or State Street against any such person.

         c. Injunctive Relief. The Customer acknowledges that the disclosure of
any Proprietary Information, or of any information which at law or equity ought
to remain confidential, will immediately give rise to continuing irreparable
injury to State Street inadequately compensable in damages at law. In addition,
State Street shall be entitled to obtain immediate injunctive relief against the
breach or threatened breach of any of the foregoing undertakings, in addition to
any other legal remedies which may be available.

termination of this Addendum.

5.       LIMITATION ON LIABILITY

agrees that any liability of State Street to the Customer or any third party
arising out of State Street's provision of Data Access Services or the System
under this Addendum shall be limited to the amount paid by the Customer for the
preceding 24 months for such services. In no event shall State Street be liable
to the Customer or any other party for any special, indirect, punitive or
consequential damages even if advised of the possibility of such damages. No
action, regardless of form, arising out of this Addendum may be brought by the
Customer more than two years after the Customer has knowledge that the cause of
action has arisen.

         b. Limited Warranties. NO OTHER WARRANTIES, WHETHER EXPRESS OR IMPLIED,
INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE, ARE MADE BY STATE STREET.

         c. Third-Party Data. Organizations from which State Street may obtain
certain data included in the System or the Data Access Services are solely
responsible for the contents of such data, and State Street shall have no
liability for claims arising out of the contents of such third-party data,
including, but not limited to, the accuracy thereof.

         d. Regulatory Requirements. As between State Street and the Customer,
the Customer shall be solely responsible for the accuracy of any accounting
statements or reports produced using the Data Access Services and the System and
the conformity thereof with any requirements of law.

         e. Force Majeure. Neither party shall be liable for any costs or
damages due to delay or nonperformance under this Addendum arising out of any
cause or event beyond such party's control, including without limitation,
cessation of services hereunder or any damages resulting therefrom to the other
party, or the Customer as a result of work stoppage, power or other mechanical
failure, computer virus, natural disaster, governmental action, or communication
disruption.

                          Trust will make every effort to maintain such

                 (b)      VALIC's or its agent's performance of or failure to

                 (c)      the bad faith, negligence or willful misconduct of
                          VALIC or its agent, whether it is performing
                          functions on behalf of the Contracts, or providing
                          Administrative Services;

                 (d)      VALIC's or its agent's furnishing to any Contract,
                          Contract owner or participant,  authorized Contract

                          inaccurate, misleading or untimely information
                          regarding any Fund or the Shares through no fault of
                          the Trust or any Fund; or

                 (e)      the breach of any representation or warranty of VALIC
                          hereunder, in each case except to the extent such
                          Losses arise out of or are attributable to another
                          party's breach of any provision of this Agreement or
                          the bad faith, negligence or willful misconduct of
                          another party in performing its obligations
                          hereunder.

         4.03.   Acts of God.  In the event that any party is unable to perform
                 its obligations under the terms of this Agreement because of
                 acts of God, strikes, equipment or transmission failure or
                 damage beyond its reasonable control, or other causes beyond
                 its reasonable control, such party shall not be liable to any
                 other party for any damages resulting from such failure to
                 perform or otherwise from such causes.

         4.04.   No Consequential Damages.  No party to this Agreement shall be
                 liable to any other party for consequential damages under any
                 provision of this Agreement.

         4.05.   Claim Procedure.  In order that the indemnification provisions
                 contained herein shall apply, upon the assertion of a claim or
                 loss for which any party (the "Indemnitor") may be required to
                 indemnify another party (the "Indemnitee"), the Indemnitee
                 shall promptly notify the Indemnitor of such assertion or
                 loss, and shall keep the Indemnitor advised with respect to
                 all developments concerning any such claim.  The Indemnitor
                 shall have the option to participate at its expense with the
                 Indemnitee in the defense of any such claim.  In the event
                 that there is more than one Indemnitor with respect to any
                 such claim, the Indemnitors shall agree as to their exercise
                 of this option.  The Indemnitee shall in no case confess any
                 claim or make any compromise in any case in which the
                 Indemnitor may be required to indemnify it except with the
                 Indemnitor's prior written consent.  The obligations of the
                 Trust and VALIC under this Section 4 shall survive the
                 termination of this Agreement.

5.       ACKNOWLEDGMENTS

         5.1.    Fees Solely for Administrative Services.  The parties hereto
                 acknowledge that the Administrative Fees are for
                 administrative and recordkeeping services only and do not
                 constitute payment in any manner for investment advisory or
                 distribution services or services of an underwriter or
                 principal underwriter within the meaning of the Securities Act
                 or the 1940 Act.  The parties acknowledge that VALIC has been





                                      8
<PAGE>   9
                 providing and will continue to provide certain services to the
                 Contract owners and participants as agent of the Contracts,
                 which, may involve, among other things, preparing
                 informational or promotional materials relating to their
                 services that may refer to the Funds and responding to
                 telephone inquiries from Contract owners and participants.
                 The parties acknowledge that the provision of such services
                 and any other actions of VALIC related to the Funds and not
                 specifically authorized herein are outside the scope of this
                 Agreement.

         5.2.    VALIC Acting as Agent for the Contracts; Supervision.  The
                 parties acknowledge that VALIC has been selected as a provider
                 of administrative and recordkeeping services by the Contracts,
                 and that, except as provided specifically in Section 1.01(b)
                 hereof, VALIC will perform the Administrative Services
                 hereunder as an independent contractor and not as an employee
                 or agent of the Trust or any Fund.  The parties acknowledge,
                 further, that neither the Trust nor any Fund undertakes to
                 supervise VALIC in the performance of the Administrative
                 Services; that neither the Trust nor any Fund shall be
                 responsible for the performance of the Administrative Services
                 by VALIC; that neither the Trust nor any Fund shall be
                 responsible for the accuracy of the records maintained by
                 VALIC for the Contracts; and that neither the Trust nor any
                 Fund shall be responsible for the  performance of other
                 functions by VALIC for the Contracts and the Contracts owners
                 and participants.  This Agreement does not entitle VALIC to
                 purchase any Shares for its own account.

         5.3.    Laws Applicable to Funds. VALIC acknowledges that the Trust is
                 a registered investment company under the 1940 Act, is subject
                 to the provisions of the 1940 Act and regulations thereunder,
                 and that the offer and sale of Shares of the Funds are subject
                 to the provisions of federal and state laws and regulations
                 applicable to the offer and sale of securities.  The Trust
                 acknowledges that VALIC is not responsible for the Trust's or
                 any Fund's compliance with such laws and regulations.  If the
                 Trust or any  Fund notifies VALIC that a procedure or other
                 activity of the VALIC related to the discharge of either of
                 its obligations hereunder has or may have the effect of
                 causing the Trust or any Fund to violate any of such laws or
                 regulations,VALIC and the Trust, on behalf of the Funds, shall
                 develop a mutually agreeable alternative procedure or activity
                 which does not have such effect.

         5.4.    Agents of VALIC and the Trust.  Each party shall notify the
                 other parties to this Agreement prior to the use of any agent.
                 To the extent agents perform services under this Agreement
                 that are the responsibility of VALIC, as the case may be,
                 VALIC shall be responsible for, and assume all liability for
                 (including any obligation for indemnification as provided in
                 Sections 4.02 or 4.03 hereof, as applicable), the actions and
                 inactions of such agents as if such services had been provided
                 by VALIC.  Similarly, to the extent agents of the Trust
                 perform services under this Agreement that are the
                 responsibility of the Trust, the Trust shall be responsible
                 for, and assume all liability for (including any obligation
                 for indemnification as provided in Section





                                      9
<PAGE>   10
                 4.01 hereof), the actions and inactions of such agents as if
                 such services had been provided by the Trust.

6.       DIVERSIFICATION

         The Funds will at all times invest money from the Contracts in such a
manner as to ensure that the Contracts will be treated as variable contracts
under the Internal Revenue Code and the regulations thereunder.  Without
limiting the scope of the foregoing, the Funds will at all times comply with
Section 817(h) of the Code and Treasury Regulation 1.817-5, relating to the
diversification requirements for variable annuity, endowment or life insurance
contracts and any amendments or other modifications to such Section or
Regulation.

                 its signature below without requiring the other parties'
                 signatures and shall be effective as of the date of execution,
                 unless any other party objects in writing within thirty (30)

                 for any reason to perform the services contemplated by this
                 Agreement, or (b) the performance by VALIC of the services
                 contemplated by this Agreement becomes in the Trust's
                 reasonable judgment unlawful or ceases to satisfy the Trust's
                 reasonable standards and so becomes unacceptable to the
                 terminating party.

                 performance by the Trust of the obligations contemplated by
                 this Agreement becomes, in the reasonable judgment of VALIC,
                 unlawful or ceases to satisfy the VALIC's reasonable standards
                 and so becomes unacceptable to VALIC.

         7.05.   Termination For Cause By Any Party.  This Agreement may be
                 terminated by any party hereto immediately upon notice to each

                 investment alternatives under all the Contracts, (b) the Trust
                 declines to accept any additional purchase or redemption
                 requests for Shares, (c) the

                 information required to be retained by such party under
                 applicable laws or regulations.  This provision shall survive

    (the "Registration Statement") under the Securities Act of 1933, as amended
    (the "Securities Act") of American General Series Portfolio Company 3 (the

    an indefinite number of shares of beneficial interest of the Company

         We have reviewed the actions taken by the Trustees of the Company to

    In this connection we have examined the Agreement and Declaration of Trust
    of the Company and the By-Laws of the Company, the Registration Statement of
    the Trust to be filed with the Securities and Exchange Commission on or
    about September 3, 1998, including the prospectus and statement of

    the Company and of public officials as to matters of fact, and such other
    documents and instruments, certified or otherwise identified to our
    satisfaction, and such questions of law and fact, as we have considered
    necessary or appropriate for the purpose of rendering the opinions expressed
    herein. In such examination we have assumed, without independent
    verification, the genuineness of all signatures (whether original or
    photostatic), the authenticity of all documents submitted to us as
    originals, and the conformity to authentic original documents of all
    documents submitted to us as certified or photostatic copies. As to all

                             SUBSCRIPTION AGREEMENT

         Agreement between The Variable Annuity Life Insurance Company
(hereinafter "VALIC"), a stock life insurance company existing under and by
virtue of the laws of the State of Texas and American General Series Portfolio
Company 3 (hereinafter the "Fund"), a business trust organized and existing
under and by virtue of the laws of the State of Delaware.

         In consideration of the mutual promises set forth herein, the parties
agree as follows:

         1. The Fund agrees to sell to VALIC and VALIC agrees to purchase for
the aggregate amount of $5,000,000, 500,000 shares of beneficial interest, $.01
Par Value, of the Fund's series (hereinafter the "Shares") designated the
American General Conservative Growth Lifestyle Fund.


         2. VALIC acknowledges that the Shares have not been registered under
any state or federal securities laws and that, therefore, the Fund is relying on
certain exemptions therein from such registration requirements, including
exemptions dependent on the intent of the undersigned in acquiring the Shares.
VALIC also understands that any resale of the Shares, or any part thereof, may
be subject to restrictions under state and federal securities laws, and that
VALIC may be required to bear the economic risk of an investment in the Shares
for an indefinite period of time.

         3. VALIC represents and warrants that it is acquiring the Shares solely
for its own account and solely for investment purposes and not with a view to
the resale or disposition of all or any part thereof, and that it has no present
plan or intention to sell or otherwise dispose of the Shares or any part
thereof; and

         4. VALIC agrees that it will not sell or dispose of the Shares or any
part thereof unless registration statements with respect to such Shares are then
in effect under the Securities Act of 1933 and under any applicable state
securities laws or unless the undersigned shall have delivered to the Fund an
opinion of counsel acceptable to the Fund, in form and substance acceptable to
the Fund, that no such registration is necessary.

         IN WITNESS THEREOF, the parties hereto have executed this Agreement by
their duly authorized representatives this 1st day of September, 1998.
