PROSPECTUS
 
   
The Variable Annuity Life Insurance Company ("VALIC") offers certain Series of
Portfolio Director Plus that consist of group and individual variable annuity
contracts (the "Contracts") to Participants in certain employer sponsored
retirement plans. Portfolio Director Plus may be available to you when you
participate in a retirement program that qualifies for deferral of federal
income taxes. Non-qualified contracts are also available for certain employer
plans as well as for certain after-tax arrangements that are not part of an
employer's plan.
    
 
Portfolio Director Plus permits you to invest in and receive retirement benefits
in up to 2 Fixed Account Options and/or an array of up to 30 of the 53 Variable
Account Options described in this prospectus. If your contract is part of your
employer's retirement program, that program will describe which Variable Account
Options are available to you. If your contract is a tax-deferred nonqualified
annuity that is not part of your employer's retirement plan, those Variable
Account Options that are invested in Mutual Funds available to the public
outside of annuity contracts, life insurance contracts, or certain employer-
sponsored retirement plans will not be available within your contract.

     of 0.20% on assets in excess of $0 but less than $75 million, and 0.25% on
     assets equal to or in excess of $75 million.
    
 
   
 (5) For these Funds the Total Separate Account Fee equals the VALIC Separate
     Account A mortality and expense risk fee plus the administration and
     distribution fee reduced by the Separate Account Expense Reimbursement. The
     Separate Account Expense Reimbursement reflects a voluntary expense
     reimbursement made by the Company directly to the Division, which may be
     terminated by the Company at any time without notice.
    
 
 (6) OTHER EXPENSES includes custody, accounting, reports to shareholders,
     audit, legal, administrative and other miscellaneous expenses. See each

     expenses of the Trust so that the Trust's expense ratio per annum will not
     exceed the expense ratio per annum of the Fund by more than 0.10% of the
     Trust's average daily net assets. This arrangement can be terminated on
     sixty days' notice. For this Fund, MANAGEMENT FEES include administration
     expenses. For the Trust's 1998 fiscal year, NB did not bear any expenses.

SUMMARY
    
- --------------------------------------------------------------------------------
 
Portfolio Director Plus is VALIC's combination fixed and variable annuity that
offers you a wide choice of investment options and flexibility. A summary of
Portfolio Director Plus's major features is presented below. For a more detailed
discussion of Portfolio Director Plus, please read the entire prospectus
carefully.
 
FIXED AND VARIABLE OPTIONS
 
Portfolio Director Plus offers a choice from among 53 Variable Account Options.
You will not be able to invest in all of the Variable Account Options described
below within a single group or individual annuity contract. If your contract is
a tax-deferred nonqualified annuity that is not part of your employer's
retirement plan, those Variable Account Options that are invested in Mutual
Funds available to the public outside of annuity contracts or life insurance
contracts will not be available within your contract. If your contract is part
of your employer's retirement program, that program will describe which Variable
Account Options are available to you. Portfolio Director Plus also offers two
Fixed Account Options.

*  A series of American General Series Portfolio Company ("AGSPC").

(1)  Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of Bankers Trust Corporation. On November 30, 1998,
     Bankers Trust Corporation entered into an Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
     Corporation and all of its subsidiaries would merge with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a
     major global banking institution that is engaged in a wide range of financial services, including retail and commercial
     banking, investment banking and insurance. The merger is contingent upon various regulatory approvals. On April 20, 1999, the
     AGSPC Fund's Board of Directors approved a new investment sub-advisory agreement with Bankers Trust Company, subject to
     shareholder approval and the Trustees of AGSPC 3 also approved a new investment sub-advisory agreement with Bankers Trust
     Company, which is not subject to shareholder approval. If the merger is approved and completed, Deutsche Bank AG, as the
     Sub-Adviser's new parent company, will control the operations of the Sub-Adviser. Bankers Trust believes that, under this new
     arrangement, the services provided to the Fund will be maintained at their current level.

SUMMARY -- (CONTINUED)
    
- --------------------------------------------------------------------------------
 
A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
 
INTEREST GUARANTEED DEATH
BENEFIT
Portfolio Director Plus offers a death benefit with an interest guarantee when
death occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director Plus offers a tax-free loan provision for tax-qualified
contracts that gives you access to your money in either of the Fixed Account
Options, subject to a minimum loan amount of $1,000. The availability of loans
is subject to government regulations, as well as your employer's plan
provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e., loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
 
There is no charge to transfer the money in your account among Portfolio
Director Plus's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you have withdrawn. The second amount is
5% of the contributions you made to your account during the last 60 months.
 
Withdrawals are always subject to your plan provisions and federal tax
restrictions, which generally include a tax penalty on withdrawals made prior to
age 59 1/2.
 
PREMIUM TAX CHARGE
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
aggregate annualized rate of 0.75% to 1.25% on the average daily net asset value
of VALIC Separate Account A. Reductions in the mortality and expense risk fee
and administration and distribution fee may be available for plan types meeting
certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
 
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.

PAYOUT OPTIONS
When you withdraw your money, you can select from several payout options: a
lifetime annuity (which guarantees payment for as long as you live), periodic
withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.
 
FEDERAL TAX INFORMATION
 
Although deferred annuity contracts such as Portfolio Director Plus can be
purchased with after-tax dollars, they are primarily used in connection with
retirement programs which receive favorable tax treatment under federal law.
 
PURCHASE REQUIREMENTS
 
Purchase Payments may be made at any time and in any amount, subject to plan
limitations.
 
For a more detailed
discussion of these income
tax provisions, see the
"FEDERAL TAX MATTERS"

(3) Effective with the merger of Quality Growth Fund into Stock Index Fund on
    May 1, 1992, Quality Growth Division 9 was merged into Stock Index Division
    10. The merger of Divisions was accomplished by an exchange of units of
    Quality Growth Division 9 for units of Stock Index Division 10 of equivalent
    value as calculated at the close of business on April 30, 1992.
    
 
Financial statements of VALIC Separate Account A are included in the Statement
of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

Financial statements of VALIC Separate Account A are included in the Statement
of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

ABOUT PORTFOLIO DIRECTOR PLUS
 
Portfolio Director Plus was developed to help you save money for your
retirement. It offers you a combination of fixed and variable investment options
that you can invest in to help you reach your retirement savings goals. Your
contributions to Portfolio Director Plus can come from different sources, like

prospectus.
 
You may choose, depending upon your retirement savings goals, your personal risk

ABOUT VALIC SEPARATE ACCOUNT A
 
When you direct money to Portfolio Director Plus's Variable Account Options, you
will be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director Plus. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account. VALIC
Separate Account A is made up of what we call "Divisions." Fifty-three Divisions
are available and represent the Variable Account Options in Portfolio Director
Plus. Each of these Divisions invests in a different Mutual Fund made available
through Portfolio Director Plus. For example, Division Ten represents and
invests in the AGSPC Stock Index Fund. The earnings (or losses) of each Division
are credited to (or charged against) the assets of that Division, and do not
affect the performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25, 1979 under Texas insurance law
to allow you to be able to invest in a number of Variable Account Options
available in Portfolio Director Plus. VALIC Separate Account A is registered
with the SEC as a unit investment trust under the Investment Company Act of 1940
("Act"). Units of interest in VALIC Separate Account A are registered as
securities under the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director Plus, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director Plus,
the Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director Plus be held exclusively for the benefit of
the contract owner, participants, annuitants, and beneficiaries of Portfolio
Director Plus. When we discuss performance information in this prospectus, we
mean the performance of a VALIC Separate Account A Division.

In addition to the investment objectives, the Account Value of an assumed

form as well as the Standard Average Annual Total Return for certain Divisions
for a 1, 3, 5 and 10 year period, if available. If Standard Average Annual

available. The performance information in the tables and graphs will reflect a
deduction for separate account fees (mortality and expense risk fees plus
administration and distribution fees minus any applicable reimbursements) and
underlying fund charges. They will not reflect any deduction for account
maintenance fees, surrender charges and premium taxes. These charges would
further reduce your return. The Account Values shown in the graphs reflect
Separate Account performance based on the performance of the underlying Fund for
the last 10 fiscal years or, since inception of the underlying Fund if for less
than 10 years. The returns shown in the tables reflect for the AGSPC Funds
actual historical performance of the related Separate Account Divisions. The
returns shown in the tables for certain Funds (Divisions 18-20) reflect actual
historical performance of the related Separate Account Divisions since inception
of each Division (July 11, 1994) and hypothetical performance for periods prior
to July 11, 1994. The returns shown in the tables for certain Funds (Divisions
21-32) reflect actual historical performance of the related Separate Account
Divisions since inception of each Division (July 1, 1996) and hypothetical
performance for periods prior to July 1, 1996. The returns shown in the tables
for certain Funds (Divisions 51-54) reflect actual historical performance of the
related Separate Account Division since inception of each Division (September
22, 1998) and hypothetical performance for periods prior to September 22, 1998.
The returns shown in the tables for certain Funds (Divisions 55-57) reflect
actual historical performance of the related Funds since inception of each Fund.
Since the AGSPC 3 Funds recently commenced operations no actual performance
exists. Hypothetical performance is based on the actual performance of the
underlying Fund reduced by Separate Account fees that would have been incurred
during the hypothetical period. Investment return and principal value will
fluctuate with market conditions, and for foreign investments, currencies and
the economic and political climates of the countries where investments are made.
Past performance cannot predict or guarantee future results.
    
 
The Standard Average Annual Total Return figures show the average percentage
change in the value of an investment in a Division from the beginning to the end
of the historical periods shown below. The results shown are after all charges
and fees have been applied against the Division. This will include account
maintenance fees and surrender charges that would have been deducted if you
surrendered Portfolio Director Plus at the end of the specified period. Premium
taxes are not deducted. This information is calculated for each Division based
on how an initial investment of $1,000 performed at the end of the specified
periods shown.
 
For more information about how these returns were calculated including a
statement of the charges reflected and tables showing historical performance
information see "How to Review Investment Performance of Separate Account
Divisions" in this prospectus.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director Plus account is surrendered before the Payout Period.
The amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director Plus was purchased.
 
PURCHASE PAYMENTS
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account.
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>
<CAPTION>
                         Initial    Subsequent
     Contract Type       Payment     Payment

Periodic Payment         $   30        $ 30
Single Payment           $1,000         -0-
</TABLE>
 
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments within 5 business days if the requested information is not
  provided, unless you otherwise so specify.
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under those circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment in an "Employer-Directed"
  account invested in the Money Market Division option chosen by your employer.
  You may not transfer these amounts until VALIC has received a completed
  application or enrollment form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  Money Market Division option chosen by your employer. We will send you
  follow-up letters requesting the information necessary to complete the
  application, including your allocation instructions. Unless a completed
  application or enrollment form is received by us within 105 days of
  establishment of your starter account, the account balance, including
  earnings, will be returned to your employer. We are not responsible for any
  adverse tax consequences to you that may result from the return of your
  employer's contributions.
 
PURCHASE UNITS
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
The Purchase Unit value for a Division is calculated as shown below:
Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income and capital gains and losses (whether
  realized or unrealized) on that day from the assets attributable to the
  Division.
/ (DIVIDED BY)
  The value of the Division for the immediately preceding day on which the
  values are calculated.
 
   
PURCHASE PAYMENTS -- an
    
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director Plus.
 
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.
 
For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.
 
                                                                              49
<PAGE>   62
 
- --------------------------------------------------------------------------------
 
We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the Exchange is open.
 
Step 2: Calculate net investment rate for any day as follows:
 
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
 
  Purchase Unit Value for that day.
= (EQUALS)
  Purchase Unit Value for immediate preceding day.
X (MULTIPLIED BY)
  Net Investment Rate (as calculated in Step 2) plus 1.00.
 
CHOOSING INVESTMENT OPTIONS
There are 55 investment options offered in Portfolio Director Plus. This
includes 2 Fixed Account Options and 53 Variable Account Options. The Funds that
underlie the Variable Account Options are registered as investment companies
under and are subject to regulation of the Act. The Fixed Account Options are
not subject to regulation under the Act and are not required to be registered
under the Securities Act of 1933. As a result, the SEC has not reviewed data in
this prospectus that relates to the Fixed Account Options. However, federal
securities law does require such data to be accurate and complete.
 
FIXED ACCOUNT OPTIONS
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in "Summary" appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
 
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed Account Options
= (EQUALS)
  All Purchase Payments made to the Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable Account Options to the Fixed
  Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn from Fixed Account Options
  (including applicable fees and charges)
 
VARIABLE ACCOUNT OPTIONS
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. As noted elsewhere in the prospectus, you will not be permitted to
select from more than 30 Variable Account Options, and in some cases less than
30, depending on your employer's plan and the type of annuity contract selected.
A complete discussion of each of the Variable Account Options may be found in
the "Variable Account Options" section in this prospectus. Based upon a Variable
Account Option's Purchase Unit Value your account will be credited with the
applicable number of Purchase Units. The Purchase Unit Value of each Variable
Account Option will change daily depending upon the investment performance of
the underlying fund (which may be positive or negative) and the deduction of
VALIC Separate Account A charges. See the "Fees and Charges" section in this
prospectus. Because Purchase Unit Values change daily, the number of Purchase
Units your account will be credited with for subsequent Purchase Payments will
vary. Each Variable Account Option bears its own investment risk. Therefore, the
value of your account may be worth more or less at retirement or withdrawal.
 
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director Plus account has been surrendered.
The value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any

TRANSFERS BETWEEN INVESTMENT OPTIONS
- --------------------------------------------------------------------------------
 
You may transfer all or part of your Account Value between the various Fixed
Account and Variable Account Options in Portfolio Director Plus without a
charge. Transfer instructions may be made either in writing or by telephone as
discussed below. Transfers may be made during the Purchase Period or during the
Payout Period. We reserve the right to limit transfers as discussed below. Your
employer's plan may also limit your rights to transfer.
 
DURING THE PURCHASE PERIOD
During the Purchase Period, transfers may be made between Portfolio Director
Plus's Fixed Account Options and Variable Account Options.
 
We currently permit transfers between Variable Account Options or from Variable
Account Options to Fixed Account Options, at any time. We may, however, limit
the number of transfers you can make.

COMMUNICATING TRANSFER OR
REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director Plus, should
be sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
 
- - The next date values are calculated.

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director Plus, you may be subject to six basic types
of fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director Plus is issued to certain types of plans which are expected to result
in lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
 
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is
 
actually withdrawn. We consider all Purchase Payments to be withdrawn before
earnings are withdrawn.
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
 
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

- --------------------------------------------------------------------------------
 
- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy of a Social Security Administration determination or a doctor's
  verification; or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director Plus is
issued to certain types of plans which are expected to result in lower costs to
VALIC. To learn more about how we determine if a surrender charge may be reduced
or waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an annualized rate of 0.75% to 1.25% on the average daily net asset value of
VALIC Separate Account A. The exact rate depends on the Variable Account Option
selected. This charge is guaranteed and cannot be increased by the Company. The
mortality and expense risk fee is to compensate the Company for assuming
mortality and expense risks under Portfolio Director Plus. The mortality risk
that the Company assumes is the obligation to provide payments during the Payout
Period for your life no matter how long that might be. In addition, the Company
assumes the obligation to pay during the Purchase Period an interest guaranteed
death benefit. For more information about the interest guaranteed death benefit
see the "Death Benefit" section of this prospectus. The expense risk is our
obligation to cover the cost of issuing and administering Portfolio Director
Plus, no matter how large the cost may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing (including but not limited to
enrollment, participant communication and education).
 
For more information about the mortality and expense risk fee and administration
and distribution fee, see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGES
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to its investment adviser. These
charges and other Fund charges and expenses are fully described in the
prospectuses for the Funds. These charges indirectly cost you because they lower
your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.
 
                                                                              53

- --------------------------------------------------------------------------------
 
REDUCTION OR WAIVER OF ACCOUNT
MAINTENANCE FEE, SURRENDER,
MORTALITY AND EXPENSE RISK FEE OR ADMINISTRATION AND DISTRIBUTION FEE CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender charges, mortality and expense risk fee or administration and
distribution fee for Portfolio Director Plus may be reduced or waived. We may
reduce or waive these fees and charges if we determine that your retirement
program will allow us to reduce or eliminate administrative or sales expenses
that we usually incur for retirement programs. There are a number of factors we
will review in determining whether your retirement program will allow us to
reduce or eliminate these administrative or sales expenses:
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
  We review the following additional factors to determine whether we can reduce
  or waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
  We review the following additional factors to determine whether we can reduce
  or waive the mortality and expense risk fee or administration and distribution
  fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
  We will only do this if permitted by this Contract and by VALIC guidelines in
  effect at the time. In no event will the reduction or waiver of fees and
  charges be permitted where the reduction or waiver will unfairly discriminate
  against any person.
 
  SEPARATE ACCOUNT EXPENSE
  REIMBURSEMENT
 
  Some of the Mutual Funds or their affiliates may have an agreement with the
  Company to pay the Company for certain administrative and shareholder services
  it provides to the underlying Fund. The Company will reduce its charges to the
  Division investing in that Fund by the full amount of any of these payments it
  receives. In addition, the Company currently reimburses certain Divisions a
  portion of the Company's administration and distribution fee. Such
  reimbursement arrangements are voluntary. See the Fee Table in this prospectus
  for an identification of those Funds for which a reimbursement applies.

<PAGE>   67
 
PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
(1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
With a Variable Payout, you may select from your existing Variable Account
Options. Your payments will vary accordingly. This is due to the varying
investment results that will be experienced by each of the Variable Account
Options you selected. The Payout Unit Value is calculated just like the Purchase
Unit Value for each Variable Account Option except that the Payout Unit Value
includes a factor for the Assumed Investment Rate you select. For additional
information on how Payout Payments and Payout Unit Values are calculated, see
the Statement of Additional Information.
 
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the Variable Account Option is lower than your
Assumed Investment Rate, your next payment will be less than your first payment.
 
COMBINATION FIXED AND VARIABLE
PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
PAYOUT DATE
The Payout Date is the dates elected by you on which your payout (annuity)
payments will start. The dates elected must be the first of any month provided
30 days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              55
<PAGE>   68
 
- --------------------------------------------------------------------------------
 
    - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
      lifetime. Upon your death, your beneficiary will receive a lump sum
      payment equal to the remaining Annuity Value.
 
    - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
      lifetime of you and your beneficiary. Upon the death of one, payments
      continue during the lifetime of the survivor. This option is designed
      primarily for couples who require maximum possible variable payouts during
      their joint lives and are not concerned with providing for beneficiaries
      at death of the last survivor. For example, it would be possible under
      this option for the Joint Annuitants to receive only one payment if both
      Annuitants died prior to the date of the second payment, or for the Joint
      Annuitants to receive only one payment and the surviving Annuitant to
      receive only one payment if one Annuitant died prior to the date of the
      second payment and the surviving Annuitant dies prior to the date of the
      third payment.
 
    - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
      number of years between five and thirty. Upon your death, payments will
      continue to your beneficiary until the designated period is completed.
 
   
ENHANCEMENTS TO PAYOUT OPTIONS
    
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. The Joint and Survivor
Life Option may be available with a one to twenty year guaranteed period option.
Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option,
 
  - The payments will be guaranteed for a 10 year period,
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis, and
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or the plan.

PAYOUT OPTIONS OR
ENHANCEMENTS

available under the Contract,

Additional Information".

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.

</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See your current Fund(s)' prospectuses
for a discussion of the reasons why the redemption of shares may be suspended or
postponed.
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
 
Under the FLORIDA STATE OPTIONAL RETIREMENT PROGRAM, no surrender or partial
surrender of Purchase Payments made by the employer will be allowed except for
termination of employment, retirement or death. Benefit payments based on
payments from the employer may not be paid in a lump sum or for a period
certain, but must be paid under a life contingency option, except for:
 
  - death benefits; and
 
  - certain small amounts approved by the State of Florida.
 
Under the LOUISIANA OPTIONAL RETIREMENT PLAN retirement benefits must be paid in
the form of a lifetime income, and except for death benefits, single sum
surrenders and partial surrenders out of the plan are not permitted.
 
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
 
PARTIAL SURRENDERS
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Options first unless otherwise specified by you.
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director Plus. There will be no surrender charge for withdrawals using this
method, which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
revoked, a systematic withdrawal may not be elected again. No more than one
systematic
 
                                                                              57
<PAGE>   70
 
- --------------------------------------------------------------------------------
 
withdrawal election may be in effect at any one time. We reserve the right to
discontinue any or all systematic withdrawals or to change its terms, at any
time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW.
There will be no surrender charge on a minimum distribution required by federal
tax law (known as No Charge Minimum Distribution), if the withdrawal:
 
  - Is made payable to you; and
 
  - Does not exceed the amount required under federal tax law as determined by
    the values in your Portfolio Director Plus Contract and VALIC.
 
This contract feature will not be available in any year that an amount has been
withdrawn under the no charge systematic withdrawal method. See "Federal Tax
Matters" in this prospectus and in the Statement of Additional Information for
more information about required distributions imposed by tax law.
 
For an explanation of possible adverse tax consequences of a surrender, see
"Federal Tax Matters" in this prospectus and in the Statement of Additional
Information.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director Plus. These other contracts are listed below. We
will allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director Plus. This exchange privilege will be available
only to other contracts purchased through your employer-sponsored retirement
plan and for which we have not yet started making payments under a Payout
Option. If you elect to exercise one of these exchange offers, you should
contact any of our Regional Offices at the addresses shown in the back of this
prospectus. An exchange may require the issuance of a contract or may be subject
to any other requirements that the Company may impose.
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
  - Exchanges from Portfolio Director Plus to other contract forms are not
    permitted.
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director Plus. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director Plus. For example, you
will be subject to the rules concerning transfers among investment options as
stated in the Transfers Between Investment Options section in this prospectus.
We may, at our option, waive any transfer restrictions for a stated period of
time. If we waive these transfer restrictions, you will be allowed to exchange
to any investment option available in Portfolio Director Plus.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director Plus.
 
SURRENDER CHARGES
 
We will generally not impose existing surrender charges as a result of your
electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director Plus will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director Plus,
the contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director Plus will be the same date as the other contract, but
no earlier than January 1, 1982. (The effect of this is to potentially shorten
the charge period for Purchase Payments subsequently made to Portfolio Director
Plus.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director Plus for purposes of calculating the surrender charge. The effective
dates of these Purchase Payments will also be retained for surrender charge
purposes.
 
The Portfolio Director Plus surrender charge is calculated assuming the most
recent Purchase Payments are removed first. This policy may cause exchanged
funds to be accessible only after charges are imposed.

AGENTS' AND MANAGERS' RETIREMENT PLAN
EXCHANGE OFFER
 
General. All eligible agents and managers of the Company are allowed to
participate in the Company's Agents' and Managers' Retirement Plan ("Plan"). We
grant to participants in the Plan the right to effect a voluntary exchange of
their units of interest under the SA-1 Contracts, Independence Plus Contracts,
Portfolio Director Contracts and Portfolio Director 2 Contracts for the
equivalent units of interest in Portfolio Director Plus.
 
Agents and managers of VALIC who enter into the voluntary exchange will not
incur under Portfolio Director Plus any surrender charges or account maintenance
fees. Other individuals who may exchange to Portfolio Director Plus from SA-1,
Independence Plus, Portfolio Director or Portfolio Director 2 Contracts may have
surrender charges and account maintenance fees imposed under Portfolio Director
Plus. All other provisions with regard to exchange offers referenced in the
section entitled "Exchange Offers" will apply to the Agents' and Managers'
Retirement Plan Exchange Offer.
 
Pursuant to this voluntary exchange offer, participants in the Plan will have
three options to choose from. As to the funding vehicle for their purchase
payment plan, the participant may choose to:
 
  - Remain in the SA-1 Contract, Independence Plus Contract, Portfolio Director
    Contract or Portfolio Director 2 Contract.
 
  - Leave current assets in the SA-1 Contract, Independence Plus Contract,
    Portfolio Director Contract or Portfolio Director 2 Contract and direct
    future Purchase Payments to Portfolio Director Plus; or
 
  - Transfer all current assets and future Purchase Payments to Portfolio
    Director Plus.
 
If the participant chooses to remain in either the SA-1 Contract, Independence
Plus Contract or Portfolio Director Contract or Portfolio Director 2 Contract,
future Purchase Payments and current assets will be controlled by the provisions
of the SA-1 Contract, Independence Plus Contract, Portfolio Director Contract,
or Portfolio Director 2 Contract, respectively. If the participant chooses to
leave current assets in the SA-1 Contract, the Independence Plus Contract,
Portfolio Director Contract, Portfolio

- --------------------------------------------------------------------------------
 
Director 2 Contract and direct future Purchase Payments to Portfolio Director
Plus, the current assets will be controlled by the provisions of the SA-1
Contract, the Independence Plus Contract Portfolio Director Contract or
Portfolio Director 2 Contract, respectively. The future Purchase Payments will
be controlled by the terms of Portfolio Director Plus subject to the exception
that surrender charges and account maintenance fees will not be imposed under
Portfolio Director Plus. If the participant chooses to transfer all current
assets and future Purchase Payments to Portfolio Director Plus, such current
assets and future Purchase Payments will be controlled by the provisions of
Portfolio Director Plus subject to the exception that surrender charges and
account maintenance fees will not be imposed under Portfolio Director Plus.
 
Once a participant transfers assets and future Purchase Payments to Portfolio
Director Plus the participant will not be permitted to exchange back to the SA-1
Contract, Independence Plus Contract, Portfolio Director Contract or Portfolio
Director 2 Contract. If a participant chooses to transfer future Purchase
Payments but not current assets to Portfolio Director Plus, the participant will
be allowed at a later date to transfer the current assets to Portfolio Director
Plus. For a complete analysis of the differences between the SA-1 contract, the
Independence Plus Contract or Portfolio Director Contract, Portfolio Director 2
Contract and Portfolio Director Plus, you should refer to the Statement of
Additional Information and the form of the contract or certificate for its terms
and conditions.

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director Plus will pay death benefits during either the Purchase
Period or the Payout Period. How these death benefits will be paid are discussed
below. The death benefit provisions in Portfolio Director Plus may vary from
state to state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
- - In a lump sum; or
 
- - In the form of an annuity under any of the Payout Options stated in the Payout
  Period section of this prospectus subject to the restrictions of that Payout
  Option.
 
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
- - In full within 5 years after the Annuitant's death; or
 
- - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
  - An annuity for a designated period not exceeding the Beneficiary's life
     expectancy.
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director Plus.
 
SPECIAL INFORMATION FOR INDIVIDUAL
NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the Annuitant's death. However, the Contract
will be transferred to the Contingent Owner,
if any, or to the Contract Owner's estate. Such transfers will generally be
considered a taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:
Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Fixed Account Option on date
  proof of death Is received by VALIC
  OR
  100% of Purchase Payments placed
  in Fixed Account Option
- - (minus)
  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
</TABLE>
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Variable Account Option on date
  proof of death is received by VALIC
  OR
  100% of Purchase Payments placed in
  Variable Account Options
- - (minus)
  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option
+ (plus)
  Interest at an annual rate of 3%
</TABLE>
 
Step 3: Add step 1 + 2 = Death Benefit
 
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
BENEFICIARY -- the person
designated to receive Payout
Payments upon the death of
an Annuitant.
 
ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid.
 
CONTRACT OWNER -- either
your employer or organization
in the case of a group
contract or the Annuitant in
the case of an individual
contract. If the contract is an
individual non-qualified type,
this is generally the Annuitant
but is not required to be. Also,
a Contingent Contract
Owner may be designated.
 
FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options. Currently,
the Fixed Account Options in
Portfolio Director Plus are Fixed
Account Plus and Short-Term
Fixed Account. Each option
of this type is guaranteed to
earn at least a minimum rate
of interest.
 
VARIABLE ACCOUNT
OPTIONS -- investment
options that correspond to
VALIC Separate Account A
Divisions offered by Portfolio
Director Plus. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.

<PAGE>   75
- --------------------------------------------------------------------------------
 
STANDARD DEATH BENEFIT
 
The standard death benefit is payable if death occurs on or after age 70.
 
The Standard Death Benefit will be the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Your Account Value on the Date Proof of Death is
  Received by VALIC
  OR
  100% of Purchase Payments (to Fixed
  and/or Variable Account Options)
- -- (MINUS)
  Amount of all Prior Withdrawals, Charges
  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director Plus are described in the "Payout Period"
section of this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed
       period option chosen by the deceased Participant; or
 
     - Receive the present value of any remaining payments applied under the
       Payment for a Designated Period Option for a period equal to or shorter
       than the period remaining. Spouse beneficiaries may be entitled to more
       favorable treatment under federal tax law.
 
                                                                              63

HOW TO REVIEW INVESTMENT PERFORMANCE
OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts or to the general public
before Portfolio Director Plus was first available to you. We may therefore,
advertise investment performance since the inception of the underlying Funds. In
each case, we will use the charges and fees imposed by Portfolio Director Plus
in calculating the Division's investment performance.
 
TYPES OF INVESTMENT PERFORMANCE
INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Standard Average Annual Total Return shows the average percentage change in the
value of an investment in the Division from the beginning to the end of a given
historical period. The results shown are after all charges and fees have been
applied against the Division. This will include account maintenance fees and
surrender charges that would have been deducted if you surrendered Portfolio
Director Plus at the end of each period shown. Premium taxes are not deducted.
This information is calculated for each Division based on how an initial assumed
payment of $1,000 performed at the end of 1, 3, 5 and 10 year periods. If
Standard Average Annual Return for a Division is not available for a stated
period, we may show the Standard Average Annual Return since Division inception.
    
 
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
 
NONSTANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance information of an underlying Fund
reduced by Account fees for a period prior to the inception of the corresponding
Division is nonstandard performance information regardless of whether all
account fees and charges are deducted. For Divisions 51-57, which recently
commenced operations, only Nonstandard Average Annual Total Returns are shown.
Accordingly, the Standard Average Annual Total Return for each of these
Divisions will be shown when it becomes available.
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director Plus will
stay in the Division beyond the time that a surrender charge would apply. It may
be calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the Division's Annual
Change in Purchase Unit Value.
 
DIVISIONS -- subaccounts of
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director Plus. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director Plus.
 
For more information on how
TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.
 
 64
<PAGE>   77
 
- --------------------------------------------------------------------------------
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT
INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director Plus charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC MONEY MARKET AND AMERICAN GENERAL MONEY MARKET DIVISIONS
 
We may advertise the AGSPC Money Market and American General Money Market
Divisions' Current Yield and Effective Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market or American General Money Market Divisions over a given 7-day
period. The Current Yield does not take into account surrender charges, account
maintenance fees or premium taxes. The income produced over a 7 day period is
then "annualized." This means we are assuming the amount of income produced
during the 7-day period will continue to be produced each week for an entire
year. The annualized amount is shown as a percentage of the investment. For the
AGSPC Money Market Division and the American General Money Market Division the
7-day Current Yield for the last 7 days ended December 31, 1998 was 3.64% and
3.90%, respectively.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause the Effective Yield to be higher than the Current
Yield. For the AGSPC Money Market Division and the American General Money Market
Division the 7-day Effective Yield for the last 7 days ended December 31, 1998
was 3.71% and 3.97%, respectively.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET AND AMERICAN GENERAL MONEY MARKET
DIVISIONS
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market and American General Money Market Divisions. The yield
for each of these Divisions will be determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION:
 
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
   
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate Account A
Division is printed in the eight tables below.
    
 
The information presented does not reflect the advantage under Portfolio
Director Plus of deferring federal income tax on increases in Account Value due
to earnings attributable to Purchase Payments (see "Federal Tax Matters" in the
prospectus and in the Statement of Additional Information.) The information
presented also does not reflect the advantage under Qualified Contracts of
deferring federal income tax on Purchase Payments.
 
The performance results shown in the following tables are not an estimate or
guarantee of future investment performance, and do not represent the actual
experience of amounts invested by a particular Participant.

    Divisions 51-54, the Table reflects hypothetical performance for periods
    prior to September 22, 1998 (inception date of each Division). The Table
    reflects hypothetical performance for Separate Account Divisions 55-57. The
    Standard Average Annual Total Return for Divisions 51-57 will be shown when
    it becomes available. Hypothetical performance is based on the actual
    performance of the underlying Fund reduced by Separate Account fees that
    would have been incurred during the hypothetical period.

     MidCap Index Division reflect the performance of the MidCap Index Fund
     since October 1, 1991.
 
   
**** Since the AGSPC3 Funds recently commenced operation no actual performance
     exists. The Evergreen Growth and Income Fund -- Class A Division 56, the
     Evergreen Small Cap Value Fund -- Class A Division 55 and the Evergreen
     Value Fund -- Class A Division 57 have only recently been offered through
     Portfolio Director Plus. Accordingly, no performance information is
     available for such Divisions.

  * The performance figures in the Table reflect the investment performance for
    the Funds for the stated periods and should not be used to infer that future
    performance will be the same. The Table reflects actual historical
    performance of the related Separate Account Divisions (21-32) since
    inception of each Division (July 1, 1996) and hypothetical performance for
    periods prior to July 1, 1996. With respect to Separate Account Divisions
    18-20, the Table reflects hypothetical performance for periods prior to July
    11, 1994 (inception date of each Division). With respect to Separate Account
    Divisions 51-54, the Table reflects hypothetical performance for periods
    prior to September 22, 1998 (inception date of each Division). The Table
    reflects hypothetical performance for Separate Account Divisions 51-57.
    Accordingly, the Standard Average Annual Total Return for Divisions 51-57
    will be shown when it becomes available. Hypothetical performance is based
    on the actual performance of the underlying Fund reduced by Separate Account
    fees that would have been incurred during the hypothetical period.
    
 
   
** The performance figures in the Table do not take into account the Separate
   Account Reimbursement made by the Company directly to those Divisions. If
   such reimbursements were included, the performance figures for the Divisions
   would be higher.
    
 
   
(1) On January 1, 1993, the Templeton Foreign Fund -- Class A implemented a Rule
    12b-1 plan, which affects subsequent performance. VALIC Separate Account A
    purchases shares of this fund at net asset value and without sales charges
    generally applicable to Class A shares.

    * The performance figures in the Table reflect the investment performance
      for the Divisions for the stated periods and should not be used to infer
      that future performance will be the same. The Annual and Cumulative Change
      in Purchase Unit Value figures are based on the average and cumulative
      changes in Purchase Unit Value for the stated period in a corresponding
      Division of Separate Account A for a different Contract offered by the
      Company and have been restated to take into account the fees and charges
      under Portfolio Director Plus other than the surrender charge and account
      maintenance fee. The Contracts offered by this prospectus became available
      for purchase on September 22, 1998.
    
 
   
   ** For the year in which the underlying Division commenced operations, less
      than a full year's performance has been reflected, which is not
      annualized.
    
 
  *** The performance figures in the Table do not take into account the Separate
      Account Reimbursement made by the Company directly to those Divisions. If
      such reimbursements were included, the performance figures for the
      Divisions would be higher.
 
 **** On October 1, 1991, the Fund underlying the AGSPC MidCap Index Division
      changed its name from the Capital Accumulation Fund to the MidCap Index
      Fund and amended its investment objective, investment program and
      investment restrictions accordingly. The performance figures for the AGSPC
      MidCap Index Division reflect the performance of the MidCap Index Fund
      since October 1, 1991.
 
   
***** Since the AGSPC3 Fund recently commenced operations no actual performance
      exists. The Evergreen Growth and Income Fund -- Class A Division 56, the
      Evergreen Small Cap Value Fund -- Class A Division 55, and the Evergreen
      Value Fund -- Class A Division 57 have only recently been offered through
      Portfolio Director Plus. Accordingly, no performance information is
      available for such Divisions.

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director
Plus was issued in connection with a nonqualified and unfunded deferred
compensation plan.
 
DETERMINATION OF FUND SHARES
ATTRIBUTABLE TO YOUR ACCOUNT
 
During Purchase Period
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
During Payout Period or after a Death
Benefit Has Been Paid
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director Plus
may have a number of shareholders including VALIC Separate Account A, VALIC's
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies and public shareholders.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
VALIC Separate Account A will vote the shares of the Funds it holds based on,
and in the same proportion as, the voting instructions received from
participants in VALIC Separate Account A.
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.

FEDERAL TAX MATTERS
- --------------------------------------------------------------------------------
 
Portfolio Director Plus provides tax-deferred accumulation over time, but is
subject to federal income and excise taxes, mentioned briefly below. You should
refer to the Statement of Additional Information for further details. Section
references are to the Internal Revenue Code ("Code"). We do not attempt to
describe any potential estate or gift tax, or any applicable state, local or
foreign tax law other than possible premium taxes mentioned under "Premium Tax
Charge." Remember that future legislation could modify the rules discussed
below, and always consult your personal tax adviser regarding how the current
rules apply to your specific situation.
 
TYPE OF PLANS
 
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program, as a Section 408(b) Individual
Retirement Annuity ("IRA"), or is instead a nonqualified Contract. Portfolio
Director Plus is used under the following types of retirement arrangements:
 
  - Section 403(b) annuities for employees
     of public schools and
     Section 501(c)(3) tax-exempt
     organizations;
 
  - Section 401(a) and 403(a) qualified plans of for-profit employers and other
    employers (including self-employed individuals);
 
  - Section 408(b) IRAs;
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
  - Section 408(k) SEPs of employers;
 
  - Section 408(p) SIMPLE retirement accounts.
 
The foregoing Contracts are "Qualified Contracts." Certain series of Portfolio
Director Plus may also be available through a nondeductible Section 408A "Roth"
individual retirement annuity ("Roth IRA").
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
In addition, Portfolio Director Plus is also available through "Non-Qualified
Contracts." Such Non-Qualified Contracts generally include unfunded,
nonqualified deferred compensation plans of corporate employers, as well as
individual annuity contracts issued to individuals outside of the context of any
formal employer or employee retirement plan or arrangement. Non-Qualified
Contracts generally may invest only in mutual funds which are not available to
the general public outside of annuity contracts or life insurance contracts.
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director Plus can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Qualified Contracts receive deferral of tax on
the inside build-up of earnings on invested Purchase Payments, until a
distribution occurs. See the Statement of Additional Information for special
rules, including those applicable to taxable, non-natural owners of
Non-Qualified Contracts.
 
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
 
Distributions are taxed differently depending on the program through which
Portfolio Director Plus is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
Amounts subject to income tax may also incur excise or penalty taxes, under the
circumstances described in the Statement of Additional Information. Generally,
they would also be subject to some form of federal income tax withholding unless
rolled into another tax-deferred vehicle. Required withholding will vary
according to type of program, type of payment and
 
 78
<PAGE>   91
 
- --------------------------------------------------------------------------------
 
your tax status. In addition, amounts received under all Contracts may be
subject to state income tax withholding requirements.
 
It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if purchase payments under the contract are invested in
publicly available mutual funds. In a ruling published in 1981, the Internal
Revenue Service ("IRS") had taken the position that, where purchase payments
under a variable annuity contract are invested in publicly available mutual
funds, the contract owner should be treated as the owner of the mutual fund
shares, and deferred tax treatment under the contract should not be available.
In the opinion of VALIC and its tax counsel, the 1981 ruling has been superseded
by subsequent legislation (Code Section 817(h)) which specifically exempts these
Qualified Contracts, and the IRS has no viable legal basis or reason to apply
the theory of the 1981 ruling to these Qualified Contracts under current law.
Although VALIC can provide no assurance that the IRS will not challenge the
deferred tax treatment of these Qualified Contracts under the theory of the 1981
ruling, VALIC and its tax counsel believe that Contract owners would prevail if
such a challenge were made.
 
It is also the opinion of VALIC and its tax counsel that for each other type of
Qualified Contract an independent exemption provides tax deferral regardless of
how ownership of the Mutual Fund shares might be imputed for federal income tax
purposes.
 
Investment earnings on contributions to Non-Qualified Contracts which are not
owned by natural persons will be taxed currently to the owner and such contracts
will not be treated as annuities for federal income tax purposes.
 
EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director Plus Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
                        THE POWER OF TAX-DEFERRED GROWTH
                                  [BAR GRAPH]
 
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. The deduction of
fees and charges for both tax-deferred plans is reflected in the chart. Variable
options incur mortality and expense risk fee and administration and distribution
fee charges (0.75% - 1.25%) and may also incur account maintenance fees ($3.75
per quarter) and surrender charges (5% of the lesser of all contributions
received during the last 60 months or the amount withdrawn). The dotted lines
represent the amounts remaining after withdrawal and payment of taxes and any
surrender charge. An additional 10% tax penalty may apply to withdrawals before
age 59 1/2. This information is for illustrative purposes only and is not a
guarantee of future return.
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.
 
To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE
REDUCED BY THE IMPACT OF INCOME TAXES UPON WITHDRAWAL. The yield will vary
 
                                                                              79
<PAGE>   92

depending upon the timing of withdrawals. The previous chart represents (without
factoring in fees and charges) after-tax amounts that would be received.
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

This chart assumes a 28% federal income tax rate. The $700 which is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800 while the full $2,500 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a tax-
qualified retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-qualified retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
YEAR 2000 RISKS
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
  - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
    Problem. This plan includes the five steps that we believe are essential to
    Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or
    replace systems that are not Year 2000 ready; (4) test systems to prove that
    they will work correctly into the year 2000; and (5) return the systems to
    operations. As of December 31, 1998, we have substantially completed all
    steps with respect to our critical systems.
    
 
   
  - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that
    must also be Year 2000 ready. Third parties are companies that provide
    certain services to VALIC. Third parties are different from internal systems
    in that VALIC has less, or no, control over their Year 2000 readiness. VALIC
    has developed a plan to review and try to lessen the Year 2000 risks of
    third parties. As of December 31, 1998, VALIC has substantially completed
    its review of third party Year 2000 risks. VALIC intends to test third party
    Year 2000 readiness throughout 1999.
    
 
   
  - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
    associated with the Year 2000 Problem. The contingency plans for third party
    relationships include the following activities: (1) evaluate the
    consequences of any failures associated with the Year 2000 Problem; (2)
    determine the chance of a Year 2000-related failure for systems that have a
    high chance of failing; (3) develop an action plan to complete contingency
    plans for those systems that rank high in both impact of failure and chance
    of failure; and (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.
    
 
                                                                              81

PROSPECTUS
 
   
The Variable Annuity Life Insurance Company ("VALIC") offers certain Series of
Portfolio Director Plus that consist of group and individual variable annuity
contracts (the "Contracts") to Participants in certain employer sponsored
retirement plans. Portfolio Director Plus 1.20 to 12.20 consists of group
variable annuity contracts that are offered by VALIC to Participants in certain
employer retirement plans. Portfolio Director Plus may be available to you when
you participate in a retirement program that qualifies for deferral of federal
income taxes. Non-qualified contracts are also available for certain employer
plans, as well as for certain after-tax arrangements that are not part of an
employer's plan.
    
 
Portfolio Director Plus permits you to invest in and receive retirement benefits
in up to 2 Fixed Account Options and/or an array of up to 30 of the 53 Variable
Account Options described in this prospectus. If your contract is part of your
employer's retirement program, that program will describe which Variable Account
Options are available to you. If your contract is a tax-deferred nonqualified
annuity that is not part of your employer's retirement plan, those Variable
Account Options that are invested in Mutual Funds available to the public
outside of annuity contracts, life insurance contracts or certain employer
sponsored retirement plans will not be available within your contract.

This prospectus is being given to you to help you make decisions for selecting
various investment options and benefits to plan and save for your retirement. It
is intended to provide you with information about VALIC, Portfolio Director
Plus, and saving for your retirement.
 
The purpose of Variable Account Options and Variable Payout Options is to
provide you investment returns which are greater than the effects of inflation.
We cannot, however, guarantee that this purpose will be achieved.
 
This prospectus describes a contract in which units of interest in VALIC's
Separate Account A are offered. Portfolio Director Plus will allow you to
accumulate retirement dollars in Fixed Account Options and/or Variable Account
Options. This prospectus describes only the variable aspects of Portfolio
Director Plus except where the Fixed Account Options are specifically mentioned.
 
For specific information about the Variable Account Options, you should refer to
the mutual fund prospectuses you have been given with this document. You should
keep these prospectuses to help answer any questions you may have in the future.

Note: These examples should not be considered representations of past or future
expenses for VALIC Separate Account A or for any Fund. Actual expenses may be
greater or less than those shown above. Similarly, the 5% annual rate of return

This Fee Table shows all charges and expenses which may be deducted from the
assets of VALIC Separate Account A and from the Funds in which VALIC Separate

SUMMARY
    
- --------------------------------------------------------------------------------
Portfolio Director Plus is VALIC's combination fixed and variable annuity that
offers you a wide choice of investment options and flexibility. A summary of
Portfolio Director Plus's major features is presented below. For a more detailed
discussion of Portfolio Director Plus, please read the entire prospectus
carefully.
 
FIXED AND VARIABLE OPTIONS
 
Portfolio Director Plus offers a choice from among 53 Variable Account Options.
You will not be able to invest in all of the Variable Account Options described
below within a single group or individual annuity contract. If your contract is
a tax-deferred nonqualified annuity that is not part of your employer's
retirement plan, those Variable Account Options that are invested in Mutual
Funds available to the public outside of annuity contracts or life insurance
contracts will not be available within your contract. If your contract is part
of your employer's retirement program, that program will describe which Variable
Account Options are available to you. Portfolio Director Plus also offers two
Fixed Account Options.

 (1) Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of Bankers Trust Corporation. On November 30, 1998,
     Bankers Trust Corporation entered into an Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
     Corporation and all of its subsidiaries would merge with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a
     major global banking institution that is engaged in a wide range of financial services, including retail and commercial
     banking, investment banking and insurance. The merger is contingent upon various regulatory approvals. On April 20, 1999, the
     AGSPC Fund's Board of Directors approved a new investment sub-advisory agreement with Bankers Trust Company, subject to
     shareholder approval and the Trustees of AGSPC 3 also approved a new investment sub-advisory agreement with Bankers Trust
     Company, which is not subject to shareholder approval. If the merger is approved and completed, Deutsche Bank AG, as the
     Sub-Adviser's new parent company, will control the operations of the Sub-Adviser. Bankers Trust believes that, under this new
     arrangement, the services provided to the Fund will be maintained at their current level.

SUMMARY -- (CONTINUED)
    
- --------------------------------------------------------------------------------
 
A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
 
INTEREST GUARANTEED DEATH
BENEFIT
Portfolio Director Plus offers a death benefit with an interest guarantee when
death occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director Plus offers a tax-free loan provision for tax-qualified
contracts that gives you access to your money in either of the Fixed Account
Options, subject to a minimum loan amount of $1,000. The availability of loans
is subject to government regulations, as well as your employer's plan
provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e., loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
There is no charge to transfer the money in your account among Portfolio
Director Plus's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you
have withdrawn. The second amount is 5% of the contributions you made to your
account during the last 60 months.
 
Withdrawals are always subject to your plan provisions and federal tax
restrictions, which generally include a tax penalty on withdrawals made prior to
age 59 1/2.
 
PREMIUM TAX CHARGE
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
aggregate annualized rate of 0.55% to 1.05% during the Purchase Period and 0.75%
to 1.25% during the Payout Period on the average daily net asset value of VALIC
Separate Account A. Reductions in the mortality and expense risk fee and
administration and distribution fee may be available for plan types meeting
certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.
 
SEPARATE ACCOUNT EXPENSE REIMBURSEMENT
The Company will reimburse to certain Divisions any fees it receives from the
Mutual Fund or its affiliate or distributor for providing the Mutual Fund
administrative and shareholder services. In addition, the Company currently
reimburses certain Divisions a portion of the Company's administration and
distribution fee for providing Variable Account Options. Such reimbursement
arrangements are voluntary. For more information as to which Variable Account
Options have a Separate Account Expense Reimbursement see the Fee Table.
 
PAYOUT OPTIONS
When you withdraw your money, you can select from several payout options: a
lifetime annuity (which guarantees payment for as long as you live), periodic
withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.
 
FEDERAL TAX INFORMATION
Although deferred annuity contracts such as Portfolio Director Plus can be
purchased with after-tax dollars, they are primarily used in connection with
retirement programs which receive favorable tax treatment under federal law.
 
PURCHASE REQUIREMENTS
Purchase Payments may be made at any time and in any amount, subject to plan
limitations.
 
To learn more about the
INTEREST GUARANTEED DEATH
BENEFIT, refer to the section
in the prospectus entitled
"Death Benefits."
 
More information on FEES
may be found in the
prospectus under the
headings "FEES AND
CHARGES" AND "FEE TABLE."
 
For a more detailed
discussion of these income
tax provisions, see the
"FEDERAL TAX MATTERS"
section of the prospectus and
of the Statement of Additional
Information.
 
For more information on
PURCHASE PAYMENTS, refer
to the "Purchase Period"
section of the prospectus.

(3) Effective with the merger of Quality Growth Fund into Stock Index Fund on
    May 1, 1992, Quality Growth Division 9 was merged into Stock Index Division
    10. The merger of Divisions was accomplished by an exchange of units of
    Quality Growth Division 9 for units of Stock Index Division 10 of equivalent
    value as calculated at the close of business on April 30, 1992.
    
 
   
Financial statements of VALIC Separate Account A are included in the Statement
of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

ABOUT VALIC SEPARATE ACCOUNT A
 
When you direct money to Portfolio Director Plus's Variable Account Options, you
will be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director Plus. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account. VALIC
Separate Account A is made up of what we call "Divisions." Fifty-three Divisions
are available and represent the Variable Account Options in Portfolio Director
Plus. Each of these Divisions invests in a different Mutual Fund made available
through Portfolio Director Plus. For example, Division Ten represents and
invests in the AGSPC Stock Index Fund. The earnings (or losses) of each Division
are credited to (or charged against) the assets of that Division, and do not
affect the performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25, 1979 under Texas insurance law
to allow you to be able to invest in a number of Variable Account Options
available in Portfolio Director Plus. VALIC Separate Account A is registered
with the SEC as a unit investment trust under the Investment Company Act of 1940
("Act"). Units of interest in VALIC Separate Account A are registered as
securities under the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director Plus, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director Plus,
the Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director Plus be held exclusively for the benefit of
the contract owner, participants, annuitants, and beneficiaries of Portfolio
Director Plus. When we discuss performance information in this prospectus, we
mean the performance of a VALIC Separate Account A Division.

SUMMARY OF FUNDS
 
   
A brief summary of the investment objectives of each Mutual Fund is shown below.
In addition to the investment objectives, the Account Value of an assumed
$10,000 investment in each of the Divisions is shown in both table and graph
form as well as the Standard Average Annual Total Return for certain Divisions
for a 1, 3, 5 and 10 year period, if available. If Standard Average Annual
Return for a Division is not available for a stated period, we may show the
Standard Average Annual Return since Division inception. We will show the
Standard Average Annual Return for Divisions 51-57, which recently commenced
operations when it becomes available. The performance information in the tables
and graphs will reflect a deduction for separate

account fees (mortality and expense risk fees plus administration and
distribution fees minus any applicable reimbursements) and underlying fund
charges. They will not reflect any deduction for account maintenance fees,
surrender charges and premium taxes. These charges would further reduce your
return. The Account Values shown in the graphs reflect Separate Account
performance based on the performance of the underlying Fund for the last 10
fiscal years or, since inception of the underlying Fund if for less than 10
years. The returns shown in the tables reflect for the AGSPC Funds actual
historical performance of the related Separate Account Divisions. The returns
shown in the tables for certain Funds (Divisions 18-20) reflect actual
historical performance of the related Separate Account Divisions since inception
of each Division (July 11, 1994) and hypothetical performance for periods prior
to July 11, 1994. The returns shown in the tables for certain Funds (Divisions
21-32) reflect actual historical performance of the related Separate Account
Divisions since inception of each Division (July 1, 1996) and hypothetical
performance for periods prior to July 1, 1996. The returns shown in the tables
for certain Funds (Divisions 51-54) reflect actual historical performance of the
related Separate Account Division since inception of each Division (September
22, 1998) and hypothetical performance for periods prior to September 22, 1998.
The returns shown in the tables for certain Funds (Divisions 55-57) reflect
actual historical performance of the related Funds since inception of each Fund.
Since the AGSPC 3 Funds recently commenced operations no actual performance
exists. Hypothetical performance is based on the actual performance of the
underlying Fund reduced by Separate Account fees that would have been incurred
during the hypothetical period. Investment return and principal value will
fluctuate with market conditions, and for foreign investments, currencies and
the economic and political climates of the countries where investments are made.
Past performance cannot predict or guarantee future results.
    
 
The Standard Average Annual Total Return figures are based on the average
percentage change in the value of an investment in a corresponding Division for
a different series of Portfolio Director Plus from the beginning to the end of
the historical periods shown and have been restated to take into account the
fees and charges under this series of Portfolio Director Plus. The results shown
are after all charges and fees have been applied against the Division. This will
include account maintenance fees and surrender charges that would have been
deducted if you surrendered Portfolio Director Plus at the end of the specified
period. Premium taxes are not deducted. This information is calculated for each
Division based on how an initial investment of $1,000 performed at the end of
the specified periods shown.
 
For more information about how these returns were calculated including a
statement of the charges reflected and tables showing historical performance
information see "How to Review Investment Performance of Separate Account
Divisions" in this prospectus.

VANGUARD WELLINGTON FUND*
(Division 25)
 
- ---------------------------------------------------------------
 
INVESTMENT OBJECTIVE
 
Seeks to conserve capital and provide moderate long-term growth and moderate
income. The Fund invests approximately 60% to 70% of its assets in dividend-
paying stocks of established, large- and medium-sized companies that, in the
adviser's opinion, are undervalued but whose prospects are improving. The
remaining 30% to 40% of assets are invested primarily in high-quality,
longer-term corporate bonds with some exposure to U.S. Treasury, government
agency, and mortgage-backed bonds.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director Plus account is surrendered before the Payout Period.
The amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director Plus was purchased.
 
PURCHASE PAYMENTS
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account.
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>
<CAPTION>
                         Initial    Subsequent
     Contract Type       Payment     Payment

Periodic Payment         $   30        $ 30
Single Payment           $1,000         -0-
</TABLE>
 
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments within 5 business days if the requested information is not
  provided, unless you otherwise so specify.
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under those circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment
 
  in an "Employer-Directed" account invested in the Money Market Division option
  chosen by your employer. You may not transfer these amounts until VALIC has
  received a completed application or enrollment form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  Money Market Division option chosen by your employer. We will send you
  follow-up letters requesting the information necessary to complete the
  application, including your allocation instructions. Unless a completed
  application or enrollment form is received by us within 105 days of
  establishment of your starter account, the account balance, including
  earnings, will be returned to your employer. We are not responsible for any
  adverse tax consequences to you that may result from the return of your
  employer's contributions.
 
PURCHASE UNITS
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
The Purchase Unit value for a Division is calculated as shown below:
Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income and capital gains and losses (whether
  realized or unrealized) on that day from the assets attributable to the
  Division.
/ (DIVIDED BY)
  The value of the Division for the immediately preceding day on which the
  values are calculated.
 
   
    
 
   
PURCHASE PAYMENTS -- an
    
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director Plus.
 
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.
 
For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.
 
                                                                              49
<PAGE>   153
 
- --------------------------------------------------------------------------------
 
We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the Exchange is open.
Step 2: Calculate net investment rate for any day as follows:
 
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
 
  Purchase Unit Value for that day.
= (EQUALS)
  Purchase Unit Value for immediate preceding day.
X (MULTIPLIED BY)
  Net Investment Rate (as calculated in Step 2) plus 1.00.
 
CHOOSING INVESTMENT OPTIONS
There are 55 investment options offered in Portfolio Director Plus. This
includes 2 Fixed Account Options and 53 Variable Account Options. The Funds that
underlie the Variable Account Options are registered as investment companies
under and are subject to regulation of the Act. The Fixed Account Options are
not subject to regulation under the Act and are not required to be registered
under the Securities Act of 1933. As a result, the SEC has not reviewed data in
this prospectus that relates to the Fixed Account Options. However, federal
securities law does require such data to be accurate and complete.
 
Fixed Account Options
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in "Summary" appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed Account Options
= (EQUALS)
  All Purchase Payments made to the Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable Account Options to the Fixed
  Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn from Fixed Account Options
  (including applicable fees and charges)
 
Variable Account Options
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. As noted elsewhere in the prospectus, you will not be permitted to
select from more than 30 Variable Account Options, and in some cases less than
30, depending on your employer's plan and the type of annuity contract selected.
A complete discussion of each of the Variable Account Options may be found in
the "Variable Account Options" section in this prospectus. Based upon a Variable
Account Option's Purchase Unit Value your account will be credited with the
applicable number of Purchase Units. The Purchase Unit Value of each Variable
Account Option will change daily depending upon the investment performance of
the underlying fund (which may be positive or negative) and the deduction of
VALIC Separate Account A charges. See the "Fees and Charges" section in this
prospectus. Because Purchase Unit Values change daily, the number of Purchase
Units your account will be credited with for subsequent Purchase Payments will
vary. Each Variable Account Option bears its own investment risk. Therefore, the
value of your account may be worth more or less at retirement or withdrawal.
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director Plus account has been surrendered.
The value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any
such account closure will be subject to applicable distribution restrictions
under the contract and/or under your employer's plan.
 
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value

The value of a Purchase Unit

Account Division you have
selected.

COMMUNICATING TRANSFER OR
REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director Plus, should
be sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
 
- - The next date values are calculated.
 
ACCOUNT VALUE -- the total
sum of your Fixed Account
and/or Variable Account

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director Plus, you may be subject to six basic types
of fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director Plus is issued to certain types of plans which are expected to result
in lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
 
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is
 
actually withdrawn. We consider all Purchase Payments to be withdrawn before
earnings are withdrawn.
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
 
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy of a Social Security Administration determination or a doctor's
  verification; or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director Plus is
issued to certain types of plans which are expected to result in lower costs to
VALIC. To learn more about how we determine if a surrender charge may be reduced
or waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an aggregate annualized rate of 0.55% to 1.05% during the Purchase Period and
0.75% to 1.25% during the Payout Period on the average daily net asset value of
VALIC Separate Account A. The exact rate depends on the Variable Account Option
selected. This charge is guaranteed and cannot be increased by the Company. The
mortality and expense risk fee is to compensate the Company for assuming
mortality and expense risks under Portfolio Director Plus. The mortality risk
that the Company assumes is the obligation to provide payments during the Payout
Period for your life no matter how long that might be. In addition, the Company
assumes the obligation to pay during the Purchase Period an interest guaranteed
death benefit. For more information about the interest guaranteed death benefit
see the "Death Benefit" section of this prospectus. The expense risk is our
obligation to cover the cost of issuing and administering Portfolio Director
Plus, no matter how large the cost may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing (including but not limited to
enrollment, participant communication and education).
 
For more information about the mortality and expense risk fee and administration
and distribution fee, see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGES
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to its investment adviser. These
charges and other Fund charges and expenses are fully described in the
prospectuses for the Funds. These charges indirectly cost you because they lower
your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.
 
                                                                              53

REDUCTION OR WAIVER OF ACCOUNT
MAINTENANCE FEE, SURRENDER,
MORTALITY AND EXPENSE RISK FEE OR
ADMINISTRATION AND DISTRIBUTION FEE
CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender charges, mortality and expense risk fee or administration and
distribution fee for Portfolio Director Plus may be reduced or waived. We may
reduce or waive these fees and charges if we determine that your retirement
program will allow us to reduce or eliminate administrative or sales expenses
that we usually incur for retirement programs. There are a number of factors we
will review in determining whether your retirement program will allow us to
reduce or eliminate these administrative or sales expenses:
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
We review the following additional factors to determine whether we can reduce or
waive the mortality and expense risk fee or administration and distribution fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
We will only do this if permitted by this Contract and by VALIC guidelines in
effect at the time. In no event will the reduction or waiver of fees and charges
be permitted where the reduction or waiver will unfairly discriminate against
any person.
 
SEPARATE ACCOUNT EXPENSE
REIMBURSEMENT
 
Some of the Mutual Funds or their affiliates may have an agreement with the
Company to pay the Company for certain administrative and shareholder services
it provides to the underlying Fund. The Company will reduce its charges to the
Division investing in that Fund by the full amount of any of these payments it
receives. In addition, the Company currently reimburses certain Divisions a
portion of the Company's administration and distribution fee. Such reimbursement
arrangements are voluntary. See the Fee Table in this prospectus for an
identification of those Funds for which a reimbursement applies.

PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
(1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
With a Variable Payout, you from your existing Variable Account Options. Your
payments will vary accordingly. This is due to the varying investment results
that will be experienced by each of the Variable Account Options you selected.
The Payout Unit Value is calculated just like the Purchase Unit Value for each
Variable Account Option except that the Payout Unit Value includes a factor for
the Assumed Investment Rate you select. For additional information on how Payout
Payments and Payout Unit Values are calculated, see the Statement of Additional
Information.
 
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the Variable Account Option is lower than your
Assumed Investment Rate, your next payment will be less than your first payment.
 
COMBINATION FIXED AND VARIABLE
PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
PAYOUT DATE
The Payout Date is the date elected by you on which your payout (annuity)
payments will start. The date elected must be the first of any month provided 30
days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              55
<PAGE>   159
 
- --------------------------------------------------------------------------------
 
    - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
      lifetime. Upon your death, your beneficiary will receive a lump sum
      payment equal to the remaining Annuity Value.
 
    - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
      lifetime of you and your beneficiary. Upon the death of one, payments
      continue during the lifetime of the survivor. This option is designed
      primarily for couples who require maximum possible variable payouts during
      their joint lives and are not concerned with providing for beneficiaries
      at death of the last survivor. For example, it would be possible under
      this option for the Joint Annuitants to receive only one payment if both
      Annuitants died prior to the date of the second payment, or for the Joint
      Annuitants to receive only one payment and the surviving Annuitant to
      receive only one payment if one Annuitant died prior to the date of the
      second payment and the surviving Annuitant dies prior to the date of the
      third payment.
 
    - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
      number of years between five and thirty. Upon your death, payments will
      continue to your beneficiary until the designated period is completed.
 
ENHANCEMENTS TO PAYOUT OPTIONS
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. The Joint and Survivor
Life Option may be available with a one to twenty year guaranteed period option.
Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option,
 
  - The payments will be guaranteed for a 10 year period,
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis, and
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or plan.

PAYOUT OPTIONS OR
ENHANCEMENTS

Additional Information".

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.
 
AMOUNT THAT MAY BE SURRENDERED
The amount that may be surrendered at any time can be determined as follows:
 
<TABLE>
<S>                    <C>               <C>
                                               Your
                                              Account
       Allowed                               Value(1)
      Surrender           = (EQUALS)         - (MINUS)
        Value                             Any Applicable
                                             Surrender
                                              Charge
</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See your current Fund(s)' prospectuses
for a discussion of the reasons why the redemption of shares may be suspended or
postponed.
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
 
Under the FLORIDA STATE OPTIONAL RETIREMENT PROGRAM, no surrender or partial
surrender of Purchase Payments made by the employer will be allowed except for
termination of employment, retirement or death. Benefit payments based on
payments from the employer may not be paid in a lump sum or for a period
certain, but must be paid under a life contingency option, except for:
 
  - death benefits; and
 
  - certain small amounts approved by the State of Florida.
 
Under the LOUISIANA OPTIONAL RETIREMENT PLAN retirement benefits must be paid in
the form of a lifetime income, and except for death benefits, single sum
surrenders and partial surrenders out of the plan are not permitted.
 
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
 
PARTIAL SURRENDERS
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Options first unless otherwise specified by you.
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director Plus. There will be no surrender charge for withdrawals using this
method, which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
 
                                                                              57
<PAGE>   161
 
- --------------------------------------------------------------------------------
 
revoked, a systematic withdrawal may not be elected again. No more than one
systematic withdrawal election may be in effect at any one time. We reserve the
right to discontinue any or all systematic withdrawals or to change its terms,
at any time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW. There will be no surrender charge on
a minimum distribution required by federal tax law (known as No Charge Minimum
Distribution), if the withdrawal:
 
  - Is made payable to you; and
 
  - Does not exceed the amount required under federal tax law as determined by
    the values in your Portfolio Director Plus Contract and VALIC.
 
This contract feature will not be available in any year that an amount has been
withdrawn under the no charge systematic withdrawal method. See "Federal Tax
Matters" in this prospectus and in the Statement of Additional Information for
more information about required distributions imposed by tax law.
 
For an explanation of possible adverse tax consequences of a surrender, see
"Federal Tax Matters" in this prospectus and in the Statement of Additional
Information.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director Plus. These other contracts are listed below. We
will allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director Plus. This exchange privilege will be available
only to other contracts purchased through your employer-sponsored retirement
plan and for which we have not yet started making payments under a Payout
Option. If you elect to exercise one of these exchange offers, you should
contact any of our Regional Offices at the addresses shown in the back of this
prospectus. An exchange may require the issuance of a contract or may be subject
to any other requirements that the Company may impose.
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
  - Exchanges from Portfolio Director Plus to other contract forms are not
    permitted.
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director Plus. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director Plus. For example, you
will be subject to the rules concerning transfers among investment options as
stated in the Transfers Between Investment Options section in this prospectus.
We may, at our option, waive any transfer restrictions for a stated period of
time. If we waive these transfer restrictions, you will be allowed to exchange
to any investment option available in Portfolio Director Plus.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director Plus.
 
SURRENDER CHARGES
 
We will generally not impose existing surrender charges as a result of your
electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director Plus will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director Plus,
the contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director Plus will be the same date as the other contract, but
no earlier than January 1, 1982. (The effect of this is to potentially shorten
the charge period for Purchase Payments subsequently made to Portfolio Director
Plus.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director Plus for purposes of calculating the surrender charge. The effective
dates of these Purchase Payments will also be retained for surrender charge
purposes.
 
The Portfolio Director Plus surrender charge is calculated assuming the most
recent Purchase Payments are removed first. This policy may cause exchanged
funds to be accessible only after charges are imposed.
 
EXCHANGE OFFERS FOR CONTRACTS OTHER THAN
PORTFOLIO DIRECTOR PLUS

AGENTS' AND MANAGERS' RETIREMENT PLAN
EXCHANGE OFFER
 
General. All eligible agents and managers of the Company are allowed to
participate in the Company's Agents' and Managers' Retirement Plan ("Plan"). We
grant to participants in the Plan the right to effect a voluntary exchange of
their units of interest under the SA-1 Contracts, Independence Plus Contracts,
Portfolio Director Contracts and Portfolio Director 2 Contracts for the
equivalent units of interest in Portfolio Director Plus.
 
Agents and managers of VALIC who enter into the voluntary exchange will not
incur under Portfolio Director Plus any surrender charges or account maintenance
fees. Other individuals who may exchange to Portfolio Director Plus from SA-1,
Independence Plus, Portfolio Director or Portfolio Director 2 Contracts may have
surrender charges and account maintenance fees imposed under Portfolio Director
Plus. All other provisions with regard to exchange offers referenced in the
section entitled "Exchange Offers" will apply to the Agents' and Managers'
Retirement Plan Exchange Offer.
 
Pursuant to this voluntary exchange offer, participants in the Plan will have
three options to choose from. As to the funding vehicle for their purchase
payment plan, the participant may choose to:
 
  - Remain in the SA-1 Contract, Independence Plus Contract, Portfolio Director
    Contract or Portfolio Director 2 Contract.
 
  - Leave current assets in the SA-1 Contract, Independence Plus Contract,
    Portfolio Director Contract or Portfolio Director 2 Contract and direct
    future Purchase Payments to Portfolio Director Plus; or
 
  - Transfer all current assets and future Purchase Payments to Portfolio
    Director Plus.
 
If the participant chooses to remain in either the SA-1 Contract, Independence
Plus Contract or Portfolio Director Contract or Portfolio Director 2 Contract,
future Purchase Payments and current assets will be controlled by the provisions
of the SA-1 Contract, Independence Plus Contract, Portfolio Director Contract,
or Portfolio Director 2 Contract, respectively. If the participant chooses to
leave current assets in the SA-1 Contract, the Independence Plus Contract,
Portfolio Director Contract, Portfolio Director 2 Contract and direct future
Purchase Payments to Portfolio Director Plus, the current assets will be
controlled by the provisions of the SA-1 Contract, the Independence Plus
Contract Portfolio Director Contract or Portfolio Director 2 Contract,
respectively. The future Purchase Payments will be controlled by the terms of
Portfolio Director Plus subject to the
 
 60
<PAGE>   164
- --------------------------------------------------------------------------------
 
exception that surrender charges and account maintenance fees will not be
imposed under Portfolio Director Plus. If the participant chooses to transfer
all current assets and future Purchase Payments to Portfolio Director Plus, such
current assets and future Purchase Payments will be controlled by the provisions
of Portfolio Director Plus subject to the exception that surrender charges and
account maintenance fees will not be imposed under Portfolio Director Plus.
 
Once a participant transfers assets and future Purchase Payments to Portfolio
Director Plus the participant will not be permitted to exchange back to the SA-1
Contract, Independence Plus Contract, Portfolio Director Contract or Portfolio
Director 2 Contract. If a participant chooses to transfer future Purchase
Payments but not current assets to Portfolio Director Plus, the participant will
be allowed at a later date to transfer the current assets to Portfolio Director
Plus. For a complete analysis of the differences between the SA-1 contract, the
Independence Plus Contract or Portfolio Director Contract, Portfolio Director 2
Contract and Portfolio Director Plus, you should refer to the Statement of
Additional Information and the form of the contract or certificate for its terms
and conditions.

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director Plus will pay death benefits during either the Purchase
Period or the Payout Period. How these death benefits will be paid are discussed
below. The death benefit provisions in Portfolio Director Plus may vary from
state to state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
- - In a lump sum; or
 
- - In the form of an annuity under any of the Payout Options stated in the Payout
  Period section of this prospectus subject to the restrictions of that Payout
  Option.
 
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
- - In full within 5 years after the Annuitant's death; or
 
- - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
  - An annuity for a designated period not exceeding the Beneficiary's life
    expectancy.
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director Plus.
 
SPECIAL INFORMATION FOR INDIVIDUAL
NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the Annuitant's death. However, the Contract
will be transferred to the Contingent Owner,
if any, or to the Contract Owner's estate. Such transfers will generally be
considered a taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:
Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Fixed Account Option on date
  proof of death Is received by VALIC
  OR
  100% of Purchase Payments placed
  in Fixed Account Option
- - (minus)
  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
</TABLE>
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Variable Account Option on date
  proof of death is received by VALIC
  OR
  100% of Purchase Payments placed in
  Variable Account Options
- - (minus)
  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option
+ (plus)
  Interest at an annual rate of 3%
</TABLE>
 
Step 3: Add step 1 + 2 = Death Benefit
 
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
BENEFICIARY -- the person
designated to receive Payout
Payments upon the death of
an Annuitant.
 
ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid.
 
CONTRACT OWNER -- either
your employer or organization
in the case of a group
contract or the Annuitant in
the case of an individual
contract. If the contract is an
individual non-qualified type,
this is generally the Annuitant
but is not required to be. Also,
a Contingent Contract
Owner may be designated.
 
FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options. Currently,
the Fixed Account Options in
Portfolio Director Plus are Fixed
Account Plus and Short-Term
Fixed Account. Each option
of this type is guaranteed to
earn at least a minimum rate
of interest.
 
VARIABLE ACCOUNT
OPTIONS -- investment
options that correspond to
VALIC Separate Account A
Divisions offered by Portfolio
Director Plus. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.
 
 62
<PAGE>   166
 
- --------------------------------------------------------------------------------
 
STANDARD DEATH BENEFIT
 
The standard death benefit is payable if death occurs on or after age 70.
 
The Standard Death Benefit will be the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Your Account Value on the Date Proof of Death is
  Received by VALIC
  OR
  100% of Purchase Payments (to Fixed
  and/or Variable Account Options)
- -- (MINUS)
  Amount of all Prior Withdrawals, Charges
  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director Plus are described in the "Payout Period"
section of this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed
       period option chosen by the deceased Participant; or
 
     - Receive the present value of any remaining payments applied under the
       Payment for a Designated Period Option for a period equal to or shorter
       than the period remaining. Spouse beneficiaries may be entitled to more
       favorable treatment under federal tax law.
 
                                                                              63

HOW TO REVIEW INVESTMENT PERFORMANCE
OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts or to the general public
before Portfolio Director Plus was first available to you. We may therefore,
advertise investment performance since the inception of the underlying Funds. In
each case, we will use the charges and fees imposed by Portfolio Director Plus
in calculating the Division's investment performance.
 
TYPES OF INVESTMENT PERFORMANCE
INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
The Standard Average Annual Total Return figures are based on the average
percentage change in the value of an investment in a corresponding Division for
a different series of Portfolio Director Plus from the beginning to the end of
the historical periods shown and have been restated to take into account the
fees and charges under this series of Portfolio Director Plus. The results shown
are after all charges and fees have been applied against the Division. This will
include account maintenance fees and surrender charges that would have been
deducted if you surrendered Portfolio Director Plus at the end of each period
shown. Premium taxes are not deducted. This information is calculated for each
Division based on how an initial assumed payment of $1,000 performed at the end
of 1, 3, 5 and 10 year periods. If Standard Average Annual Return for a Division
is not available for a stated period, we may show the Standard Average Annual
Return since Division inception.
    
 
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
 
NONSTANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance information of an underlying trend
reduced by account fees for a period prior to the inception of the corresponding
Division is nonstandard performance information regardless of whether all
account fees and charges are deducted. For Divisions 51-57, which recently
commenced operations, only Nonstandard Average Annual Total Returns are shown.
Accordingly, the Standard Average Annual Total Return for each of these
Divisions will be shown when it becomes available
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director Plus will
stay in the Division beyond the time that a surrender charge would apply. It may
be calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period, or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the Division's Annual
Change in Purchase Unit Value.
 
DIVISIONS -- subaccounts of
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director Plus. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director Plus.
 
For more information on how
TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.
 
 64
<PAGE>   168
 
- --------------------------------------------------------------------------------
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT
INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director Plus charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC MONEY MARKET AND AMERICAN GENERAL MONEY MARKET DIVISIONS
 
We may advertise the AGSPC Money Market and American General Money Market
Divisions' Current Yield and Effective Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market or American General Money Market Divisions over a given 7-day
period. The Current Yield does not take into account surrender charges, account
maintenance fees or premium taxes. The income produced over a 7 day period is
then "annualized." This means we are assuming the amount of income produced
during the 7-day period will continue to be produced each week for an entire
year. The annualized amount is shown as a percentage of the investment. For the
AGSPC Money Market Division and the American General Money Market Division the
7-day Current Yield for the last 7 days ended December 31, 1998 was 3.84% and
4.09%, respectively.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause the Effective Yield to be higher than the Current
Yield. For the AGSPC Money Market Division and the American General Money Market
Division the 7-day Effective Yield for the last 7 days ended December 31, 1998
was 3.91% and 4.17%, respectively.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET AND AMERICAN GENERAL MONEY MARKET
DIVISIONS
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market and American General Money Market Divisions. The yield
for each of these Divisions will be determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION:
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
   
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate Account A
Division is printed in the six tables below.
    
 
The information presented does not reflect the advantage under Portfolio
Director Plus of deferring federal income tax on increases in Account Value due
to earnings attributable to Purchase Payments (see "Federal Tax Matters" in the
prospectus and in the Statement of Additional Information.) The information
presented also does not reflect the advantage under Qualified Contracts of
deferring federal income tax on Purchase Payments.
 
The performance information presented in the following tables reflects the
performance of the underlying Fund after deduction of a mortality and expense
risk fee and administration and distribution fee at an aggregate annualized rate
of 0.55% to 1.05% during the Purchase Period on the daily net asset value of
VALIC Separate Account A. The exact rate depends upon the Variable Account
Option selected.

  * The performance figures in the Table reflect the investment performance for
    the Funds for the stated periods and should not be used to infer that future
    performance will be the same. The Table reflects actual historical
    performance of the related Separate Account Divisions (21-32) since
    inception of each Division (July 1, 1996) and hypothetical performance for
    periods prior to July 1, 1996. With respect to Separate Account Divisions
    18-20, the Table reflects hypothetical performance for periods prior to July
    11, 1994 (inception date of each Division). With respect to Separate Account
    Divisions 51-54, the Table reflects hypothetical performance for periods
    prior to September 22, 1998 (inception date of each Division). The Table
    reflects hypothetical performance for Separate Account Divisions 55-57. The
    Standard Average Annual Total Return for Divisions 51-57 will be shown when
    it becomes available. Hypothetical performance is based on the actual
    performance of the underlying Fund reduced by Separate Account fees that
    would have been incurred during the hypothetical period.
    
 
 ** The performance figures in the Table do not take into account the Separate
    Account Reimbursement made by the Company directly to those Divisions. If
    such reimbursements were included, the performance figures for the Divisions
    would be higher.

   * The performance figures in the Table reflect the investment performance for
     the Divisions for the stated periods and should not be used to infer that
     future performance will be the same. The Cumulative Return figures are
     based on the percentage changes in the value of an investment in a
     corresponding Division for a different series of Portfolio Director Plus
     from the beginning to the end of the historical periods shown and have been
     restated to take into account the fees and charges under this series of
     Portfolio Director Plus other than the surrender charge and account
     maintenance fee.
    
 
  ** The performance figures in the Table do not take into account the Separate
     Account Reimbursement made by the Company directly to those Divisions. If
     such reimbursements were included, the performance figures for the
     Divisions would be higher.
 
 *** On October 1, 1991, the Fund underlying the AGSPC MidCap Index Division
     changed its name from the Capital Accumulation Fund to the MidCap Index
     Fund and amended its investment objective, investment program and
     investment restrictions accordingly. The performance figures for the AGSPC
     MidCap Index Division reflect the performance of the MidCap Index Fund
     since October 1, 1991.
 
   
**** Since the AGSPC3 Funds recently commenced operation no actual performance
     exists. The Evergreen Growth and Income Fund -- Class A Division 56, the
     Evergreen Small Cap Value Fund -- Class A Division 55 and the Evergreen
     Value Fund -- Class A Division 57 have only recently been offered through
     Portfolio Director Plus. Accordingly, no performance information is
     available for such Divisions.

  * The performance figures in the Table reflect the investment performance for
    the Funds for the stated periods and should not be used to infer that future
    performance will be the same. The Table reflects actual historical
    performance of the related Separate Account Divisions (21-32) since
    inception of each Division (July 1, 1996) and hypothetical performance for
    periods prior to July 1, 1996. With respect to Separate Account Divisions
    18-20, the Table reflects hypothetical performance for periods prior to July
    11, 1994 (inception date of each Division). With respect to Separate Account
    Divisions 51-54, the Table reflects hypothetical performance for periods
    prior to September 22, 1998 (inception date of each Division). The Table
    reflects hypothetical performance for Separate Account Divisions 55-57.
    Accordingly, the Standard Average Annual Total Return for Divisions 51-57
    will be shown when it becomes available. Hypothetical performance is based
    on the actual performance of the underlying Fund reduced by Separate Account
    fees that would have been incurred during the hypothetical period.
    
 
 ** The performance figures in the Table do not take into account the Separate
    Account Reimbursement made by the Company directly to those Divisions. If
    such reimbursements were included, the performance figures for the Divisions
    would be higher.

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director
Plus was issued in connection with a nonqualified and unfunded deferred
compensation plan.
 
DETERMINATION OF FUND SHARES
ATTRIBUTABLE TO YOUR ACCOUNT
 
During Purchase Period
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
During Payout Period or after a Death
Benefit Has Been Paid
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director Plus
may have a number of shareholders including VALIC Separate Account A, VALIC's
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies and public shareholders.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
VALIC Separate Account A will vote the shares of the Funds it holds based on,
and in the same proportion as, the voting instructions received from
participants in VALIC Separate Account A.
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.

FEDERAL TAX MATTERS
- --------------------------------------------------------------------------------
 
Portfolio Director Plus provides tax-deferred accumulation over time, but is
subject to federal income and excise taxes, mentioned briefly below. You should
refer to the Statement of Additional Information for further details. Section
references are to the Internal Revenue Code ("Code"). We do not attempt to
describe any potential estate or gift tax, or any applicable state, local or
foreign tax law other than possible premium taxes mentioned under "Premium Tax
Charge." Remember that future legislation could modify the rules discussed
below, and always consult your personal tax adviser regarding how the current
rules apply to your specific situation.
 
TYPE OF PLANS
 
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program or, as a Section 408(b) Individual
Retirement Annuity ("IRA"), or is instead a nonqualified Contract. Portfolio
Director Plus is used under the following types of retirement arrangements:
 
  - Section 403(b) annuities for employees
     of public schools and
     Section 501(c)(3) tax-exempt
     organizations;
 
  - Section 401(a) and 403(a) qualified plans of for-profit employers and other
    employers (including self-employed individuals);
 
  - Section 408(b) IRAs;
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
  - Section 408(k) SEPs of employers;
 
  - Section 408(p) SIMPLE retirement accounts.
 
The foregoing Contracts are "Qualified Contracts." Certain series of Portfolio
Director Plus may also be available through a nondeductible Section 408A "Roth"
individual retirement annuity ("Roth IRA").
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
In addition, Portfolio Director Plus is also available through "Non-Qualified
Contracts." Such Non-Qualified Contracts generally include unfunded,
nonqualified deferred compensation plans of corporate employers as well as
individual annuity contracts issued to individuals outside of the context of any
formal employer or employee retirement plan or arrangement. Non-Qualified
Contracts generally may invest only in mutual funds which are not available to
the general public outside of annuity contracts or life insurance contracts.
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director Plus can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Qualified Contracts receive deferral of tax on
the inside build-up of earnings on invested Purchase Payments, until a
distribution occurs. See the Statement of Additional Information for special
rules, including those applicable to taxable, non-natural owners of
Non-Qualified Contracts.
 
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
 
Distributions are taxed differently depending on the program through which
Portfolio Director Plus is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
Amounts subject to income tax may also incur excise or penalty taxes, under the
circumstances described in the Statement of Additional Information. Generally,
they would also be subject to some form of federal income tax withholding unless
rolled into another tax-deferred vehicle. Required withholding will vary
according to type of program, type of payment and your tax status. In addition,
amounts received under all Contracts may be subject to state income tax
withholding requirements.

<PAGE>   178
 
- --------------------------------------------------------------------------------
 
It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if purchase payments under the contract are invested in
publicly available mutual funds. In a ruling published in 1981, the Internal
Revenue Service ("IRS") had taken the position that, where purchase payments
under a variable annuity contract are invested in publicly available mutual
funds, the contract owner should be treated as the owner of the mutual fund
shares, and deferred tax treatment under the contract should not be available.
In the opinion of VALIC and its tax counsel, the 1981 ruling has been superseded
by subsequent legislation (Code Section 817(h)) which specifically exempts these
Qualified Contracts, and the IRS has no viable legal basis or reason to apply
the theory of the 1981 ruling to these Qualified Contracts under current law.
Although Valic can provide no assurance that the IRS will not challenge the
deferred tax treatment of these Qualified Contracts under the theory of the 1981
ruling, VALIC and its tax counsel believe that Contract owners would prevail if
such a challenge were made.
 
It is also the opinion of VALIC and its tax counsel that for each other type of
Qualified Contract an independent exemption provides tax deferral regardless of
how ownership of the Mutual Fund shares might be imputed for federal income tax
purposes.
 
Investment earnings on contributions to Non-Qualified Contracts which are not
owned by natural persons will be taxed currently to the owner and such contracts
will not be treated as annuities for federal income tax purposes.
 
EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director Plus Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
 
                        THE POWER OF TAX-DEFERRED GROWTH
                                  [BAR GRAPH]
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. The deduction of
fees and charges for both tax-deferred plans is reflected in the chart. Variable
options incur mortality and expense risk fee and administration and distribution
fee charges (0.55% - 1.05% during the purchase period and 0.75% - 1.25% during
the payout period) and may also incur account maintenance fees ($3.75 per
quarter) and surrender charges (5% of the lesser of all contributions received
during the last 60 months or the amount withdrawn). The dotted lines represent
the amounts remaining after withdrawal and payment of taxes and any surrender
charge. An additional 10% tax penalty may apply to withdrawals before age
59 1/2. This information is for illustrative purposes only and is not a
guarantee of future return.
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.
 
To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings
 
                                                                              75
<PAGE>   179
 
- --------------------------------------------------------------------------------
 
program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE REDUCED BY THE IMPACT
OF INCOME TAXES UPON WITHDRAWAL. The yield will vary depending upon the timing
of withdrawals. The previous chart represents (without factoring in fees and
charges) after-tax amounts that would be received.
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

</TABLE>
 
This chart assumes a 28% federal income tax rate. The $700 which is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800 while the full $2,500 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a tax-
qualified retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-qualified retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
   
YEAR 2000 RISKS
    
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
- - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
  Problem. This plan includes the five steps that we believe are essential to
  Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or replace
  systems that are not Year 2000 ready; (4) test systems to prove that they will
  work correctly into the year 2000; and (5) return the systems to operations.
  As of December 31, 1998, we have substantially completed all steps with
  respect to our critical systems.
    
 
   
- - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that must
  also be Year 2000 ready. Third parties are companies that provide certain
  services to VALIC. Third parties are different from internal systems in that
  VALIC has less, or no, control over their Year 2000 readiness. VALIC has
  developed a plan to review and try to lessen the Year 2000 risks of third
  parties. As of December 31, 1998, VALIC has substantially completed its review
  of third party Year 2000 risks. VALIC intends to test third party Year 2000
  readiness throughout 1999.
    
 
   
- - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
  associated with the Year 2000 Problem. The contingency plans for third party
  relationships include the following activities: (1) evaluate the consequences
  of any failures associated with the Year 2000 Problem; (2) determine the
  chance of a Year 2000-related failure for systems that have a high chance of
  failing; (3) develop an action plan to complete contingency plans for those
  systems that rank high in both impact of failure and chance of failure; and
  (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.

PROSPECTUS
 
   
The Variable Annuity Life Insurance Company ("VALIC") offers certain Series of
Portfolio Director Plus that consist of group and individual variable annuity
contracts (the "Contracts") to Participants in certain employer sponsored
retirement plans. Portfolio Director Plus 1.40 to 12.40 consists of group
variable annuity contracts that are offered by VALIC to Participants in certain
employer retirement plans. Portfolio Director Plus may be available to you when
you participate in a retirement program that qualifies for deferral of federal
income taxes. Non-qualified contracts are also available for certain employer
plans, as well as for certain after-tax arrangements that are not part of an
employer's plan.
    
 
Portfolio Director Plus permits you to invest in and receive retirement benefits
in up to 2 Fixed Account Options and/or an array of up to 30 of the 53 Variable
Account Options described in this prospectus. If your contract is part of your
employer's retirement program, that program will describe which Variable Account
Options are available to you. If your contract is a tax-deferred nonqualified
annuity that is not a part of your employer's retirement plan, those Variable
Account Options that are invested in Mutual Funds available to the public
outside of annuity contracts, life insurance contracts or certain employer-
sponsored retirement plans, will not be available within your contract.

This prospectus is being given to you to help you make decisions for selecting
various investment options and benefits to plan and save for your retirement. It
is intended to provide you with information about VALIC, Portfolio Director
Plus, and saving for your retirement.
 
The purpose of Variable Account Options and Variable Payout Options is to
provide you investment returns which are greater than the effects of inflation.
We cannot, however, guarantee that this purpose will be achieved.
 
This prospectus describes a contract in which units of interest in VALIC's
Separate Account A are offered. Portfolio Director Plus will allow you to
accumulate retirement dollars in Fixed Account Options and/or Variable Account
Options. This prospectus describes only the variable aspects of Portfolio
Director Plus except where the Fixed Account Options are specifically mentioned.
 
For specific information about the Variable Account Options, you should refer to
the mutual fund prospectuses you have been given with this document. You should
keep these prospectuses to help answer any questions you may have in the future.
 
   
Following this introduction is a summary of the major features and options of
Portfolio Director Plus. It is intended to provide you with a brief overview of
those sections discussed in more detail in this prospectus.

Note: These examples should not be considered representations of past or future
expenses for VALIC Separate Account A or for any Fund. Actual expenses may be
greater or less than those shown above. Similarly, the 5% annual rate of return
assumed in the examples is not an estimate or guarantee of future investment
performance. The purpose of the Fee Table above is to help Contract Owners and
Participants understand the various expenses of VALIC Separate Account A and the
Funds which are, in effect, passed on to the Contract Owners and Participants.
 
This Fee Table shows all charges and expenses which may be deducted from the
assets of VALIC Separate Account A and from the Funds in which VALIC Separate
Account A invests. For a further description of these charges and expenses, see

SUMMARY
    
- --------------------------------------------------------------------------------
 
Portfolio Director Plus is VALIC's combination fixed and variable annuity that
offers you a wide choice of investment options and flexibility. A summary of
Portfolio Director Plus's major features is presented below. For a more detailed
discussion of Portfolio Director Plus, please read the entire prospectus
carefully.
 
FIXED AND VARIABLE OPTIONS
 
Portfolio Director Plus offers a choice from among 53 Variable Account Options.
You will not be able to invest in all of the Variable Account Options described
below within a single group or individual annuity contract. If your contract is
a tax-deferred nonqualified annuity that is not part of your employer's
retirement plan, those Variable Account Options that are invested in Mutual
Funds available to the public outside of annuity contracts or life insurance
contracts will not be available within your contract. If your contract is part
of your employer's retirement program, that program will describe which Variable
Account Options are available to you. Portfolio Director Plus also offers two
Fixed Account Options.

  * A series of American General Series Portfolio Company ("AGSPC").
 ** A series of American General Series Portfolio Company 3 ("AGSPC 3").
(1) Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of Bankers Trust Corporation. On November 30, 1998,
    Bankers Trust Corporation entered into an Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
    Corporation and all of its subsidiaries would merge with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a
    major global banking institution that is engaged in a wide range of financial services, including retail and commercial
    banking, investment banking and insurance. The merger is contingent upon various regulatory approvals. On April 20, 1999, the
    AGSPC Fund's Board of Directors approved a new investment sub-advisory agreement with Bankers Trust Company, subject to
    shareholder approval and the Trustees of AGSPC 3 also approved a new investment sub-advisory agreement with Bankers Trust
    Company, which is not subject to shareholder approval. If the merger is approved and completed, Deutsche Bank AG, as the Sub-
    Adviser's new parent company, will control the operations of the Sub-Adviser. Bankers Trust believes that, under this new
    arrangement, the services provided to the Fund will be maintained at their current level.

SUMMARY -- (CONTINUED)
    
- --------------------------------------------------------------------------------
 
   
    
 
A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
 
INTEREST GUARANTEED DEATH BENEFIT
Portfolio Director Plus offers a death benefit with an interest guarantee when
death occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director Plus offers a tax-free loan provision for tax-qualified
contracts that gives you access to your money in either of the Fixed Account
Options, subject to a minimum loan amount of $1,000. The availability of loans
is subject to government regulations, as well as your employer's plan
provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e., loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
There is no charge to transfer the money in your account among Portfolio
Director Plus's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you have withdrawn. The second amount is
5% of the contributions you made to your account during the last 60 months.
Withdrawals are always subject to your plan provisions and federal tax
restrictions, which generally include a tax penalty on withdrawals made prior to
age 59 1/2.
 
PREMIUM TAX CHARGE
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
aggregate annualized rate of 0.35% to 0.85% during the Purchase Period and 0.75%
to 1.25% during the Payout Period on the average daily net asset value of VALIC
Separate Account A. Reductions in the mortality and expense risk fee and
administration and distribution fee may be available for plan types meeting
certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.
 
SEPARATE ACCOUNT EXPENSE REIMBURSEMENT
The Company will reimburse to certain Divisions any fees it receives from the
Mutual Fund or its affiliate or distributor for providing the Mutual Fund
administrative and shareholder services. In addition, the Company currently
reimburses certain Divisions a portion of the Company's administration and
distribution fee for providing Variable Account Options. Such reimbursement
arrangements are voluntary. For more information as to which Variable Account
Options have a Separate Account Expense Reimbursement see the Fee Table.
 
PAYOUT OPTIONS
When you withdraw your money, you can select from several payout options: a
lifetime annuity (which guarantees payment for as long as you live), periodic
withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.
 
FEDERAL TAX INFORMATION
Although deferred annuity contracts such as Portfolio Director Plus can be
purchased with after-tax dollars, they are primarily used in connection with
retirement programs which receive favorable tax treatment under federal law.
 
PURCHASE REQUIREMENTS
Purchase Payments may be made at any time and in any amount, subject to plan
limitations.
 
To learn more about the
INTEREST GUARANTEED DEATH
BENEFIT, refer to the section
in the prospectus entitled
"Death Benefits."
 
More information on FEES
may be found in the
prospectus under the
headings "FEES AND
CHARGES" AND "FEE TABLE."
 
For a more detailed
discussion of these income
tax provisions, see the
"FEDERAL TAX MATTERS"
section of the prospectus and
of the Statement of Additional
Information.
 
For more information on
PURCHASE PAYMENTS, refer
to the "Purchase Period"
section of the prospectus.

Financial statements of VALIC Separate Account A are included in the Statement
of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

When you direct money to Portfolio Director Plus's Variable Account Options, you
will be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director Plus. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account. VALIC
Separate Account A is made up of what we call "Divisions." Fifty-three Divisions
are available and represent the Variable Account Options in Portfolio Director
Plus. Each of these Divisions invests in a different Mutual Fund made available
through Portfolio Director Plus. For example, Division Ten represents and
invests in the AGSPC Stock Index Fund. The earnings (or losses) of each Division
are credited to (or charged against) the assets of that Division, and do not
affect the performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25 under Texas insurance law to
allow you to be able to invest in a number of Variable Account Options available
in Portfolio Director Plus. VALIC Separate Account A is registered with the SEC
as a unit investment trust under the Investment Company Act of 1940 ("Act").
Units of interest in VALIC Separate Account A are registered as securities under
the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director Plus, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director Plus,
the Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director Plus be held exclusively for the benefit of
the contract owner, participants, annuitants, and beneficiaries of Portfolio
Director Plus. When we

In addition to the investment objectives, the Account Value of an assumed
$10,000 investment in each of the Divisions is shown in both table and graph
form as well as the Standard Average Annual Total Return for certain Divisions

Annual Return for a Division is not available for a stated period, we may show
the Standard Average Annual Return since Division inception. We will show the
Standard Average Annual Return for Divisions 51-57, which recently commenced
operations when it becomes available. The performance information in the tables
and graphs will reflect a deduction for separate account fees (mortality and
expense risk fees plus administration and distribution fees minus any applicable
reimbursements) and underlying fund charges. They will not reflect any deduction
for account maintenance fees, surrender charges and premium taxes. These charges
would further reduce your return. The Account Values shown in the graphs reflect
Separate Account performance based on the performance of the underlying Fund for
the last 10 fiscal years or, since inception of the underlying Fund if for less
than 10 years. The returns shown in the tables reflect for the AGSPC Funds
actual historical performance of the related Separate Account Divisions. The
returns shown in the tables for certain Funds (Divisions 18-20) reflect actual
historical performance of the related Separate Account Divisions since inception
of each Division (July 11, 1994) and hypothetical performance for periods prior
to July 11, 1994. The returns shown in the tables for certain Funds (Divisions
21-32) reflect actual historical performance of the related Separate Account
Divisions since inception of each Division (July 1, 1996) and hypothetical
performance for periods prior to July 1, 1996. The returns shown in the tables
for certain Funds (Divisions 51-54) reflect actual historical performance of the
related Separate Account Division since inception of each Division (September
22, 1998) and hypothetical performance for periods prior to September 22, 1998.
The returns shown in the tables for certain Funds (Divisions 55-57) reflect
actual historical performance of the related Funds since inception of each Fund.
Since the AGSPC 3 Funds recently commenced operations no actual performance
exists. Hypothetical performance is based on the actual performance of the
underlying Fund reduced by Separate Account fees that would have been incurred
during the hypothetical period. Investment return and principal value will
fluctuate with market conditions, and for foreign investments, currencies and
the economic and political climates of the countries where investments are made.
Past performance cannot predict or guarantee future results.
    
 
The Standard Average Annual Total Return figures are based on the average
percentage change in the value of an investment in a corresponding Division for
a different series of Portfolio Director Plus from the beginning to the end of
the historical periods shown and have been restated to take into account the
fees and charges under this series of Portfolio Director Plus. The results shown
are after all charges and fees have been applied against the Division. This will
include account maintenance fees and surrender charges that would have been
deducted if you surrendered Portfolio Director Plus at the end of the specified
period. Premium taxes are not deducted. This information is calculated for each
Division based on how an initial investment of $1,000 performed at the end of
the period shown.
 
For more information about how these returns were calculated including a
statement of the charges reflected and tables showing historical performance
information see "How to Review Investment Performance of Separate Account
Divisions" in this prospectus.

INVESTMENT OBJECTIVE
 
Seeks to conserve capital and provide moderate long-term growth and moderate
income. The Fund invests approximately 60% to 70% of its assets in dividend-
paying stocks of established, large- and medium-sized companies that, in the
adviser's opinion, are undervalued but whose prospects are improving. The
remaining 30% to 40% of assets are invested primarily in high-quality,
longer-term corporate bonds with some exposure to U.S. Treasury, government
agency, and mortgage-backed bonds.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director Plus account is surrendered before the Payout Period.
The amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director Plus was purchased.
 
PURCHASE PAYMENTS
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account.
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>
<CAPTION>
                         Initial    Subsequent
     Contract Type       Payment     Payment

Periodic Payment         $   30        $ 30
Single Payment           $1,000         -0-
</TABLE>
 
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments, within 5 business days, if the requested information is not
  provided, unless you otherwise so specify.
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under those circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment
 
  in an "Employer-Directed" account invested in the Money Market Division option
  chosen by your employer. You may not transfer these amounts until VALIC has
  received a completed application or enrollment form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  Money Market Division option chosen by your employer. We will send you
  follow-up letters requesting the information necessary to complete the
  application, including your allocation instructions. Unless a completed
  application or enrollment form is received by us within 105 days of
  establishment of your starter account, the account balance, including
  earnings, will be returned to your employer. We are not responsible for any
  adverse tax consequences to you that may result from the return of your
  employer's contributions.
 
PURCHASE UNITS
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
The Purchase Unit value for a Division is calculated as shown below:
Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income and capital gains and losses (whether
  realized or unrealized) on that day from the assets attributable to the
  Division.
/ (DIVIDED BY)
  The value of the Division for the immediately preceding day on which the
  values are calculated.
 
   
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director Plus.
    
 
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.
 
For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.
 
                                                                              49
<PAGE>   241
 
- --------------------------------------------------------------------------------
 
We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the Exchange is open.
Step 2: Calculate net investment rate for any day as follows:
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
  Purchase Unit Value for that day.
= (EQUALS)
  Purchase Unit Value for immediate preceding day.
X (MULTIPLIED BY)
  Net Investment Rate (as calculated in Step 2) plus 1.00.
 
CHOOSING INVESTMENT OPTIONS
There are 55 investment options offered in Portfolio Director Plus. This
includes 2 Fixed Account Options and 53 Variable Account Options. The Funds that
underlie the Variable Account Options are registered as investment companies
under and are subject to regulation of the Act. The Fixed Account Options are
not subject to regulation under the Act and are not required to be registered
under the Securities Act of 1933. As a result, the SEC has not reviewed data in
this prospectus that relates to the Fixed Account Options. However, federal
securities law does require such data to be accurate and complete.
 
Fixed Account Options
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in "Summary" appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
 
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed Account Options
= (EQUALS)
  All Purchase Payments made to the Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable Account Options to the Fixed
  Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn from Fixed Account Options
  (including applicable fees and charges)
 
Variable Account Options
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. As noted elsewhere in the prospectus, you will not be permitted to
select from more than 30 Variable Account Options, and in some cases less than
30, depending on your employer's plan and the type of annuity contract selected.
A complete discussion of each of the Variable Account Options may be found in
the "Variable Account Options" section in this prospectus. Based upon a Variable
Account Option's Purchase Unit Value your account will be credited with the
applicable number of Purchase Units. The Purchase Unit Value of each Variable
Account Option will change daily depending upon the investment performance of
the underlying fund (which may be positive or negative) and the deduction of
VALIC Separate Account A charges. See the "Fees and Charges" section in this
prospectus. Because Purchase Unit Values change daily, the number of Purchase
Units your account will be credited with for subsequent Purchase Payments will
vary. Each Variable Account Option bears its own investment risk. Therefore, the
value of your account may be worth more or less at retirement or withdrawal.
 
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director Plus account has been surrendered.
The value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any
such account closure will be subject to applicable distribution restrictions
under the contract and/or under your employer's plan.
 
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.

Account and Variable Account Options in Portfolio Director Plus without a

COMMUNICATING TRANSFER OR
REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director Plus, should
be sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
 
- - The next date values are calculated.
 
ACCOUNT VALUE -- the total

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director Plus, you may be subject to six basic types
of fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director Plus is issued to certain types of plans which are expected to result
in lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
 
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is
 
actually withdrawn. We consider all Purchase Payments to be withdrawn before
earnings are withdrawn.
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
 
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy of a Social Security Administration determination or a doctor's
  verification; or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director Plus is
issued to certain types of plans which are expected to result in lower costs to
VALIC. To learn more about how we determine if a surrender charge may be reduced
or waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an aggregate annualized rate of 0.35% to 0.85% during the Purchase Period and
0.75% to 1.25% during the Payout Period on the average daily net asset value of
VALIC Separate Account A. The exact rate depends on the Variable Account Option
selected. This charge is guaranteed and cannot be increased by the Company. The
mortality and expense risk fee is to compensate the Company for assuming
mortality and expense risks under Portfolio Director Plus. The mortality risk
that the Company assumes is the obligation to provide payments during the Payout
Period for your life no matter how long that might be. In addition, the Company
assumes the obligation to pay during the Purchase Period an interest guaranteed
death benefit. For more information about the interest guaranteed death benefit
see the "Death Benefit" section of this prospectus. The expense risk is our
obligation to cover the cost of issuing and administering Portfolio Director
Plus, no matter how large the cost may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing (including but not limited to
enrollment, participant communication and education).
 
For more information about the mortality and expense risk fee and administration
and distribution fee, see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGES
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to its investment adviser. These
charges and other Fund charges and expenses are fully described in the
prospectuses for the Funds. These charges indirectly cost you because they lower
your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.
 
                                                                              53

REDUCTION OR WAIVER OF ACCOUNT
MAINTENANCE FEE, SURRENDER,
MORTALITY AND EXPENSE RISK FEE OR ADMINISTRATION AND DISTRIBUTION FEE CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender charges, mortality and expense risk fee or administration and
distribution fee for Portfolio Director Plus may be reduced or waived. We may
reduce or waive these fees and charges if we determine that your retirement
program will allow us to reduce or eliminate administrative or sales expenses
that we usually incur for retirement programs. There are a number of factors we
will review in determining whether your retirement program will allow us to
reduce or eliminate these administrative or sales expenses:
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
We review the following additional factors to determine whether we can reduce or
waive the mortality and expense risk fee or administration and distribution fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
We will only do this if permitted by this Contract and by VALIC guidelines in
effect at the time. In no event will the reduction or waiver of fees and charges
be permitted where the reduction or waiver will unfairly discriminate against
any person.
 
SEPARATE ACCOUNT EXPENSE
REIMBURSEMENT
 
Some of the Mutual Funds or their affiliates may have an agreement with the
Company to pay the Company for certain administrative and shareholder services
it provides to the underlying Fund. The Company will reduce its charges to the
Division investing in that Fund by the full amount of any of these payments it
receives. In addition, the Company currently reimburses certain Divisions a
portion of the Company's administration and distribution fee. Such reimbursement
arrangements are voluntary. See the Fee Table in this prospectus for an
identification of those Funds for which a reimbursement applies.

PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
(1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
With a Variable Payout, you may choose from your existing Variable Account
Options. Your payments will vary accordingly. This is due to the varying
investment results that will be experienced by each of the Variable Account
Options you selected. The Payout Unit Value is calculated just like the Purchase
Unit Value for each Variable Account Option except that the Payout Unit Value
includes a factor for the Assumed Investment Rate you select. For additional
information on how Payout Payments and Payout Unit Values are calculated, see
the Statement of Additional Information.
 
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the Variable Account Option is lower than your
Assumed Investment Rate, your next payment will be less than your first payment.
 
COMBINATION FIXED AND VARIABLE
PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
PAYOUT DATE
The Payout Date is the date elected by you on which your payout (annuity)
payments will start. The date elected must be the first of any month provided 30
days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              55
<PAGE>   247
 
- --------------------------------------------------------------------------------
 
    - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
      lifetime. Upon your death, your beneficiary will receive a lump sum
      payment equal to the remaining Annuity Value.
 
    - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
      lifetime of you and your beneficiary. Upon the death of one, payments
      continue during the lifetime of the survivor. This option is designed
      primarily for couples who require maximum possible variable payouts during
      their joint lives and are not concerned with providing for beneficiaries
      at death of the last survivor. For example, it would be possible under
      this option for the Joint Annuitants to receive only one payment if both
      Annuitants died prior to the date of the second payment, or for the Joint
      Annuitants to receive only one payment and the surviving Annuitant to
      receive only one payment if one Annuitant died prior to the date of the
      second payment and the surviving Annuitant dies prior to the date of the
      third payment.
 
    - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
      number of years between five and thirty. Upon your death, payments will
      continue to your beneficiary until the designated period is completed.
 
ENHANCEMENTS TO PAYOUT OPTIONS
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. The Joint and Survivor
Life Option may be available with a one to twenty year guaranteed period option.
Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option,
 
  - The payments will be guaranteed for a 10 year period,
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis, and
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or plan.

PAYOUT OPTIONS OR
ENHANCEMENTS

available under the Contract,

Additional Information".

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.
 
AMOUNT THAT MAY BE SURRENDERED
The amount that may be surrendered at any time can be determined as follows:
 
<TABLE>
<S>                    <C>               <C>
                                               Your
                                              Account
       Allowed                               Value(1)
      Surrender           = (EQUALS)         - (MINUS)
        Value                             Any Applicable
                                             Surrender
                                              Charge
</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See your current Fund(s)' prospectuses
for a discussion of the reasons why the redemption of shares may be suspended or
postponed.
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
 
Under the FLORIDA STATE OPTIONAL RETIREMENT PROGRAM, no surrender or partial
surrender of Purchase Payments made by the employer will be allowed except for
termination of employment, retirement or death. Benefit payments based on
payments from the employer may not be paid in a lump sum or for a period
certain, but must be paid under a life contingency option, except for:
 
  - death benefits; and
 
  - certain small amounts approved by the State of Florida.
 
Under the LOUISIANA OPTIONAL RETIREMENT PLAN retirement benefits must be paid in
the form of a lifetime income, and except for death benefits, single sum
surrenders and partial surrenders out of the plan are not permitted.
 
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
 
PARTIAL SURRENDERS
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Options first unless otherwise specified by you.
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director Plus. There will be no surrender charge for withdrawals using this
method, which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
 
                                                                              57
<PAGE>   249
 
- --------------------------------------------------------------------------------
 
revoked, a systematic withdrawal may not be elected again. No more than one
systematic withdrawal election may be in effect at any one time. We reserve the
right to discontinue any or all systematic withdrawals or to change its terms,
at any time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW. There will be no surrender charge on
a minimum distribution required by federal tax law (known as No Charge Minimum
Distribution), if the withdrawal:
 
  - Is made payable to you; and
 
  - Does not exceed the amount required under federal tax law as determined by
    the values in your Portfolio Director Plus Contract and VALIC.
 
This contract feature will not be available in any year that an amount has been
withdrawn under the no charge systematic withdrawal method. See "Federal Tax
Matters" in this prospectus and in the Statement of Additional Information for
more information about required distributions imposed by tax law.
 
For an explanation of possible adverse tax consequences of a surrender, see
"Federal Tax Matters" in this prospectus and in the Statement of Additional
Information.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director Plus. These other contracts are listed below. We
will allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director Plus. This exchange privilege will be available
only to other contracts purchased through your employer-sponsored retirement
plan and for which we have not yet started making payments under a Payout
Option. If you elect to exercise one of these exchange offers, you should
contact any of our Regional Offices at the addresses shown in the back of this
prospectus. An exchange may require the issuance of a contract or may be subject
to any other requirements that the Company may impose.
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
  - Exchanges from Portfolio Director Plus to other contract forms are not
    permitted.
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director Plus. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director Plus. For example, you
will be subject to the rules concerning transfers among investment options as
stated in the Transfers Between Investment Options section in this prospectus.
We may, at our option, waive any transfer restrictions for a stated period of
time. If we waive these transfer restrictions, you will be allowed to exchange
to any investment option available in Portfolio Director Plus.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director Plus.
 
SURRENDER CHARGES
 
We will generally not impose existing surrender charges as a result of your
electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director Plus will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director Plus,
the contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director Plus will be the same date as the other contract, but
no earlier than January 1, 1982. (The effect of this is to potentially shorten
the charge period for Purchase Payments subsequently made to Portfolio Director
Plus.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director Plus for purposes of calculating the surrender charge. The effective
dates of these Purchase Payments will also be retained for surrender charge
purposes.
 
The Portfolio Director Plus surrender charge is calculated assuming the most
recent Purchase Payments are removed first. This policy may cause exchanged
funds to be accessible only after charges are imposed.
 
EXCHANGE OFFERS FOR CONTRACTS OTHER THAN
PORTFOLIO DIRECTOR PLUS
 
The following other contracts may be exchanged.
 
  - Portfolio Director and Portfolio Director 2 Contracts

AGENTS' AND MANAGERS' RETIREMENT PLAN
EXCHANGE OFFER
 
General. All eligible agents and managers of the Company are allowed to
participate in the Company's Agents' and Managers' Retirement Plan ("Plan"). We
grant to participants in the Plan the right to effect a voluntary exchange of
their units of interest under the SA-1 Contracts, Independence Plus Contracts,
Portfolio Director Contracts and Portfolio Director 2 Contracts for the
equivalent units of interest in Portfolio Director Plus.
 
Agents and managers of VALIC who enter into the voluntary exchange will not
incur under Portfolio Director Plus any surrender charges or account maintenance
fees. Other individuals who may exchange to Portfolio Director Plus from SA-1,
Independence Plus, Portfolio Director or Portfolio Director 2 Contracts may have
surrender charges and account maintenance fees imposed under Portfolio Director
Plus. All other provisions with regard to exchange offers referenced in the
section entitled "Exchange Offers" will apply to the Agents' and Managers'
Retirement Plan Exchange Offer.
 
Pursuant to this voluntary exchange offer, participants in the Plan will have
three options to choose from. As to the funding vehicle for

- --------------------------------------------------------------------------------
 
their purchase payment plan, the participant may choose to:
 
  - Remain in the SA-1 Contract, Independence Plus Contract, Portfolio Director
    Contract or Portfolio Director 2 Contract.
 
  - Leave current assets in the SA-1 Contract, Independence Plus Contract,
    Portfolio Director Contract or Portfolio Director 2 Contract and direct
    future Purchase Payments to Portfolio Director Plus; or
 
  - Transfer all current assets and future Purchase Payments to Portfolio
    Director Plus.
 
If the participant chooses to remain in either the SA-1 Contract, Independence
Plus Contract or Portfolio Director Contract or Portfolio Director 2 Contract,
future Purchase Payments and current assets will be controlled by the provisions
of the SA-1 Contract, Independence Plus Contract, Portfolio Director Contract,
or Portfolio Director 2 Contract, respectively. If the participant chooses to
leave current assets in the SA-1 Contract, the Independence Plus Contract,
Portfolio Director Contract, Portfolio Director 2 Contract and direct future
Purchase Payments to Portfolio Director Plus, the current assets will be
controlled by the provisions of the SA-1 Contract, the Independence Plus
Contract Portfolio Director Contract or Portfolio Director 2 Contract,
respectively. The future Purchase Payments will be controlled by the terms of
Portfolio Director Plus subject to the exception that surrender charges and
account maintenance fees will not be imposed under Portfolio Director Plus. If
the participant chooses to transfer all current assets and future Purchase
Payments to Portfolio Director Plus, such current assets and future Purchase
Payments will be controlled by the provisions of Portfolio Director Plus subject
to the exception that surrender charges and account maintenance fees will not be
imposed under Portfolio Director Plus.
 
Once a participant transfers assets and future Purchase Payments to Portfolio
Director Plus the participant will not be permitted to exchange back to the SA-1
Contract, Independence Plus Contract, Portfolio Director Contract or Portfolio
Director 2 Contract. If a participant chooses to transfer future Purchase
Payments but not current assets to Portfolio Director Plus, the participant will
be allowed at a later date to transfer the current assets to Portfolio Director
Plus. For a complete analysis of the differences between the SA-1 contract, the

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director Plus will pay death benefits during either the Purchase
Period or the Payout Period. How these death benefits will be paid are discussed
below. The death benefit provisions in Portfolio Director Plus may vary from
state to state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
  - In a lump sum; or
 
  - In the form of an annuity under any of the Payout Options stated in the
    Payout Period section of this prospectus subject to the restrictions of that
    Payout Option.
 
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
  - In full within 5 years after the Annuitant's death; or
 
  - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
  - An annuity for a designated period
    not exceeding the Beneficiary's life expectancy.
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director Plus.
 
SPECIAL INFORMATION FOR INDIVIDUAL
NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the Annuitant's death. However, the Contract
will be transferred to the Contingent Owner,
if any, or to the Contract Owner's estate. Such transfers will generally be
considered a taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:
Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Fixed Account Option on date
  proof of death Is received by VALIC
  OR
  100% of Purchase Payments placed
  in Fixed Account Option
- - (minus)
  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
</TABLE>
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Variable Account Option on date
  proof of death is received by VALIC
  OR
  100% of Purchase Payments placed in
  Variable Account Options
- - (minus)
  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option
+ (plus)
  Interest at an annual rate of 3%
</TABLE>
 
Step 3: Add step 1 + 2 = Death Benefit
 
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
BENEFICIARY -- the person
designated to receive Payout
Payments upon the death of
an Annuitant.
 
ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid.
 
CONTRACT OWNER -- either
your employer or organization
in the case of a group
contract or the Annuitant in
the case of an individual
contract. If the contract is an
individual non-qualified type,
this is generally the Annuitant
but is not required to be. Also,
a Contingent Contract
Owner may be designated.
 
FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options. Currently,
the Fixed Account Options in
Portfolio Director Plus are Fixed
Account Plus and Short-Term
Fixed Account. Each option
of this type is guaranteed to
earn at least a minimum rate
of interest.
 
VARIABLE ACCOUNT
OPTIONS -- investment
Options that correspond to
VALIC Separate Account A
Divisions offered by Portfolio
Director Plus. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.
 
 62
<PAGE>   254
 
- --------------------------------------------------------------------------------
 
STANDARD DEATH BENEFIT
 
The standard death benefit is payable if death occurs on or after age 70.
 
The Standard Death Benefit will be the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Your Account Value on the Date Proof of Death is
  Received by VALIC
  OR
  100% of Purchase Payments (to Fixed
  and/or Variable Account Options)
- -- (MINUS)
  Amount of all Prior Withdrawals, Charges
  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director Plus are described in the "Payout Period"
section of this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed
       period option chosen by the deceased Participant; or
 
     - Receive the present value of any remaining payments applied under the
       Payment for a Designated Period Option for a period equal to or shorter
       than the period remaining. Spouse beneficiaries may be entitled to more
       favorable treatment under federal tax law.
 
                                                                              63

HOW TO REVIEW INVESTMENT PERFORMANCE
OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts or to the general public
before Portfolio Director Plus was first available to you. We may therefore,
advertise investment performance since the inception of the underlying Funds. In
each case, we will use the charges and fees imposed by Portfolio Director Plus
in calculating the Division's investment performance.
 
TYPES OF INVESTMENT PERFORMANCE
INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
Standard Average Annual Total Return figures are based on the average percentage
change in the value of an investment in a corresponding Division for a different
series of Portfolio Director Plus from the beginning to the end of the given
historical periods shown and have been restated to take into account the fees
and charges under this series of Portfolio Director Plus. The results shown are
after all charges and fees have been applied against the Division. This will
include
   
account maintenance fees and surrender charges that would have been deducted if
you surrendered Portfolio Director Plus at the end of each period shown. Premium
taxes are not deducted. This information is calculated for each Division based
on how an initial assumed payment of $1,000 performed at the end of 1, 3, 5 and
10 year periods. If Standard Average Annual Return for a Division is not
available for a stated period, we may show the Standard Average Annual Return
since Division inception.
    
 
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
 
NONSTANDARD AVERAGE ANNUAL TOTAL
RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance of an underlying Fund reduced by
Account fees for a period prior to the inception of the corresponding Division
is nonstandard performance information regardless of whether all account fees
and charges are deducted. For Divisions 51-57, which recently commenced
operations, only Nonstandard Average Annual Total Returns are shown.
Accordingly, the Standard Average Annual Total Return for each of these
Divisions will be shown when it becomes available
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director Plus will
stay in the Division beyond the time that a surrender charge would apply. It may
be calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period, or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
DIVISIONS -- subaccounts of
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director Plus. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director Plus.
 
For more information on how
TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.
 
 64
<PAGE>   256
- --------------------------------------------------------------------------------
 
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the Division's Annual
Change in Purchase Unit Value.
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT
INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director Plus charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC Money Market and American General Money Market Divisions
 
We may advertise the AGSPC Money Market and American General Money Market
Divisions' Current Yield and Effective Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market or American General Money Market Divisions over a given 7-day
period. The Current Yield does not take into account surrender charges, account
maintenance fees or premium taxes. The income produced over a 7 day period is
then "annualized." This means we are assuming the amount of income produced
during the 7-day period will continue to be produced each week for an entire
year. The annualized amount is shown as a percentage of the investment. For the
AGSPC Money Market Division and the American General Money Market Division the
7-day Current Yield for the last 7 days ended December 31, 1998 was 4.04% and
4.29%, respectively.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause the Effective Yield to be higher than the Current
Yield. For the AGSPC Money Market Division and the American General Money Market
Division the 7-day Effective Yield for the last 7 days ended December 31, 1998
was 4.12% and 4.39%, respectively.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET AND AMERICAN GENERAL MONEY MARKET
DIVISIONS
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market and American General Money Market Divisions. The yield
for each of these Divisions will be determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION:
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate Account A
Division is printed in the six tables below.
 
The information presented does not reflect the advantage under Portfolio
Director Plus of deferring federal income tax on increases in Account Value due
to earnings attributable to Purchase Payments (see "Federal Tax Matters" in the
prospectus and in the Statement of Additional Information.) The information
presented also does not reflect the advantage under Qualified Contracts of
deferring federal income tax on Purchase Payments.
 
The performance information presented in the following tables reflects the
performance of the underlying Fund after deduction of a mortality and expense
risk fee and administration and distribution fee at an aggregate annualized rate
of 0.35% to 0.85% during the Purchase Period on the daily average net asset
value of VALIC Separate Account A. The exact rate depends upon the Variable
Account Option selected.

 * The performance figures in the Table reflect the investment performance for
   the Funds for the stated periods and should not be used to infer that future
   performance will be the same. The Table reflects actual historical
   performance of the related Separate Account Divisions (21-32) since inception
   of each Division (July 1, 1996) and hypothetical performance for periods
   prior to July 1, 1996. With respect to Separate Account Divisions 18-20, the
   Table reflects hypothetical performance for periods prior to July 1, 1994
   (inception date of each Division). The Table reflects hypothetical
   performance for Separate Account Divisions 55-57. The Standard Average Total
   Return for Divisions 51-57 will be shown when it becomes available.
   Hypothetical performance is based on the actual performance of the underlying
   fund reduced by Separate Account fees that would have been incurred during
   the hypothetical period.
    
 
 ** The performance figures in the Table do not take into account the Separate
    Account Reimbursement made by the Company directly to those Divisions. If
    such reimbursements were included, the performance figures for the Divisions
    would be higher.

   * The performance figures in the Table reflect the investment performance for
     the Divisions for the stated periods and should not be used to infer that
     future performance will be the same. Since the end of the stated periods
     equity markets have moved erratically and the performance of certain
     Divisions may have diminished. The Cumulative Return figures are based on
     the percentage changes in the value of an investment in a corresponding
     Division for a different series of Portfolio Director Plus from the
     beginning to the end of the historical periods shown and have been restated
     to take into account the fees and charges under this series of Portfolio
     Director Plus other than the surrender charge and account maintenance fee.
 
  ** The performance figures in the Table do not take into account the Separate
     Account Reimbursement made by the Company directly to those Divisions. If
     such reimbursements were included, the performance figures for the
     Divisions would be higher.
 
 *** On October 1, 1991, the Fund underlying the AGSPC MidCap Index Division
     changed its name from the Capital Accumulation Fund to the MidCap Index
     Fund and amended its investment objective, investment program and
     investment restrictions accordingly. The performance figures for the AGSPC
     MidCap Index Division reflect the performance of the MidCap Index Fund
     since October 1, 1991.
 
   
**** Since the AGSPC 3 Funds recently commenced operation no actual performance
     exists. The Evergreen Growth and Income Fund -- Class A Division 56, the
     Evergreen Small Cap Value Fund -- Class A Division 55 and the Evergreen
     Value Fund -- Class A Division 57 have only recently been offered through
     Portfolio Director Plus. Accordingly, no performance information is
     available for such Divisions.

  * The performance figures in the Table reflect the investment performance for
    the Funds for the stated periods and should not be used to infer that future
    performance will be the same. The Table reflects actual historical
    performance of the related Separate Account Divisions (21-32) since
    inception of each Division (July 1, 1996) and hypothetical performance for
    periods prior to July 1, 1996. With respect to Separate Account Divisions
    18-20, the Table reflects hypothetical performance for periods prior to July
    11, 1994 (inception date of each Division). With respect to Separate Account
    Divisions 51-54, the Table reflects hypothetical performance for periods
    prior to September 22, 1998 (inception date of each Division). The Table
    reflects hypothetical performance for Separate Account Divisions 55-57.
    Accordingly, the Standard Average Annual Total Return for Divisions 51-57
    will be shown when it becomes available. Hypothetical performance is based
    on the actual performance of the underlying Fund reduced by Separate Account
    fees that would have been incurred during the hypothetical period.
    
 
 ** The performance figures in the Table do not take into account the Separate
    Account Reimbursement made by the Company directly to those Divisions. If
    such reimbursements were included, the performance figures for the Divisions
    would be higher.

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director
Plus was issued in connection with a nonqualified and unfunded deferred
compensation plan.
 
DETERMINATION OF FUND SHARES ATTRIBUTABLE TO YOUR ACCOUNT
 
During Purchase Period
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
During Payout Period or after a Death
Benefit Has Been Paid
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director Plus
may have a number of shareholders including VALIC Separate Account A, VALIC's
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies and public shareholders.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
VALIC Separate Account A will vote the shares of the Funds it holds based on,
and in the same proportion as, the voting instructions received from
participants in VALIC Separate Account A.
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.

FEDERAL TAX MATTERS
- --------------------------------------------------------------------------------
 
Portfolio Director Plus provides tax-deferred accumulation over time, but is
subject to federal income and excise taxes, mentioned briefly below. You should
refer to the Statement of Additional Information for further details. Section
references are to the Internal Revenue Code ("Code"). We do not attempt to
describe any potential estate or gift tax, or any applicable state, local or
foreign tax law other than possible premium taxes mentioned under "Premium Tax
Charge." Remember that future legislation could modify the rules discussed
below, and always consult your personal tax adviser regarding how the current
rules apply to your specific situation.
 
TYPE OF PLANS
 
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program or, as a Section 408(b) Individual
Retirement Annuity ("IRA"), or is instead a nonqualified Contract. Portfolio
Director Plus is used under the following types of retirement arrangements:
 
  - Section 403(b) annuities for employees of public schools and
    Section 501(c)(3) tax-exempt organizations;
 
  - Section 401(a) and 403(a) qualified plans of for-profit employers and other
    employers (including self-employed individuals);
 
  - Section 408(b) IRAs;
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
  - Section 408(k) SEPs of employers;
 
  - Section 408(p) SIMPLE retirement accounts.
 
The foregoing Contracts are "Qualified Contracts." Certain series of Portfolio
Director Plus may also be available through a nondeductible Section 408A "Roth"
individual retirement annuity ("Roth IRA").
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
In addition, Portfolio Director Plus is also available through "Non-Qualified
Contracts." Such Non-Qualified Contracts generally include unfunded,
nonqualified deferred compensation plans of corporate employers as well as
individual annuity contracts issued to individuals outside of the context of any
formal employer or employee retirement plan or arrangement. Non-Qualified
Contracts generally may invest only in mutual funds which are not available to
the general public outside of annuity contracts or life insurance contracts.
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director Plus can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Qualified Contracts receive deferral of tax on
the inside build-up of earnings on invested Purchase Payments, until a
distribution occurs. See the Statement of Additional Information for special
rules, including those applicable to taxable, non-natural owners of
Non-Qualified Contracts.
 
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
 
Distributions are taxed differently depending on the program through which
Portfolio Director Plus is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
Amounts subject to income tax may also incur excise or penalty taxes, under the
circumstances described in the Statement of Additional Information. Generally,
they would also be subject to some form of federal income tax withholding unless
rolled into another tax-deferred vehicle. Required withholding will vary
according to type of program, type of payment and
 
 74
<PAGE>   266
 
- --------------------------------------------------------------------------------
 
your tax status. In addition, amounts received under all Contracts may be
subject to state income tax withholding requirements.
 
It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if purchase payments under the contract are invested in
publicly available mutual funds. In a ruling published in 1981, the Internal
Revenue Service ("IRS") had taken the position that, where purchase payments
under a variable annuity contract are invested in publicly available mutual
funds, the contract owner should be treated as the owner of the mutual fund
shares, and deferred tax treatment under the contract should not be available.
In the opinion of VALIC and its tax counsel, the 1981 ruling has been superseded
by subsequent legislation (Code Section 817(h)) which specifically exempts these
Qualified Contracts, and the IRS has no viable legal basis or reason to apply
the theory of the 1981 ruling to these Qualified Contracts under current law.
Although Valic can provide no assurance that the IRS will not challenge the
deferred tax treatment of these Qualified Contracts under the theory of the 1981
ruling, VALIC and its tax counsel believe that Contract owners would prevail if
such a challenge were made.
 
It is also the opinion of VALIC and its tax counsel that for each other type of
Qualified Contract an independent exemption provides tax deferral regardless of
how ownership of the Mutual Fund shares might be imputed for federal income tax
purposes.
 
Investment earnings on contributions to Non-Qualified Contracts which are not
owned by natural persons will be taxed currently to the owner and such contracts
will not be treated as annuities for federal income tax purposes.
 
EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director Plus Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
 
                        THE POWER OF TAX-DEFERRED GROWTH
                                  [BAR GRAPH]
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. The deduction of
fees and charges for both tax-deferred plans is reflected in the chart. Variable
options incur mortality and expense risk fee and administration and distribution
fee charges (0.35% - 0.85% during the purchase period and 0.75% - 1.25% during
the payout period) and may also incur account maintenance fees ($3.75 per
quarter) and surrender charges (5% of the lesser of all contributions received
during the last 60 months or the amount withdrawn). The dotted lines represent
the amounts remaining after withdrawal and payment of taxes and any surrender
charge. An additional 10% tax penalty may apply to withdrawals before age
59 1/2. This information is for illustrative purposes only and is not a
guarantee of future return.
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.
 
                                                                              75
<PAGE>   267
 
- --------------------------------------------------------------------------------
 
To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE
REDUCED BY THE IMPACT OF INCOME TAXES UPON WITHDRAWAL. The yield will vary
depending upon the timing of withdrawals. The previous chart represents (without
factoring in fees and charges) after-tax amounts that would be received.
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

</TABLE>
 
This chart assumes a 28% federal income tax rate. The $700 which is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800 while the full $2,500 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a tax-
qualified retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-qualified retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
   
YEAR 2000 RISKS
    
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
  - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
    Problem. This plan includes the five steps that we believe are essential to
    Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or
    replace systems that are not Year 2000 ready; (4) test systems to prove that
    they will work correctly into the Year 2000; and (5) return the systems to
    operations. As of December 31, 1998, we have substantially completed all
    steps with respect to our critical systems.
    
 
   
  - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that
    must also be Year 2000 ready. Third parties are companies that provide
    certain services to VALIC. Third parties are different from internal systems
    in that VALIC has less, or no, control over their Year 2000 readiness. VALIC
    has developed a plan to review and try to lessen the Year 2000 risks of
    third parties. As of December 31, 1998, VALIC has substantially completed
    its review of third party Year 2000 risks. VALIC intends to test third party
    Year 2000 readiness throughout 1999.
    
 
   
  - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
    associated with the Year 2000 Problem. The contingency plans for third party
    relationships include the following activities: (1) evaluate the
    consequences of any failures associated with the Year 2000 Problem; (2)
    determine the chance of a Year 2000-related failure for systems that have a
    high chance of failing; (3) develop an action plan to complete contingency
    plans for those systems that rank high in both impact of failure and chance
    of failure; and (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.

PROSPECTUS
 
   
The Variable Annuity Life Insurance Company ("VALIC") offers certain Series of
Portfolio Director 2 that consist of group and individual variable annuity
contracts (the "Contracts") to Participants in certain employer sponsored
retirement plans. Portfolio Director 2 may be available to you when you
participate in a retirement program that qualifies for deferral of federal
income taxes. Non-qualified contracts are also available for certain employer
plans as well as for certain after-tax arrangements that are not part of an
employer's plan.
    
 
   
Portfolio Director 2 permits you to invest in and receive retirement benefits in
up to 2 Fixed Account Options and/or an array of up to 18 Variable Account
Options. If your contract is part of your employer's retirement program, that
program will describe which Variable Account Options are available to you. If
your contract is a tax-deferred nonqualified annuity that is not part of your
employer's retirement plan, those Variable Account Options that are invested in
Mutual Funds available to the public outside of annuity contracts, life
insurance contracts, or certain employer-sponsored retirement plans will not be
available within your contract. Each of these investment options is explained
more fully in this prospectus. Here is a list of these investment options:

This prospectus is being given to you to help you make decisions for selecting
various investment options and benefits to plan and save for your retirement. It
is intended to provide you with information about VALIC, Portfolio Director 2,
and saving for your retirement.
 
The purpose of Variable Account Options and Variable Payout Options is to
provide you investment returns which are greater than the effects of inflation.
We cannot, however, guarantee that this purpose will be achieved.
 
This prospectus describes a contract in which units of interest in VALIC's
Separate Account A are offered. Portfolio Director 2 will allow you to
accumulate retirement dollars in Fixed Account Options and/or Variable Account
Options. This prospectus describes only the variable aspects of Portfolio
Director 2 except where the Fixed Account Options are specifically mentioned.
 
For specific information about the Variable Account Options, you should refer to
the mutual fund prospectuses you have been given with this document. You should
keep these prospectuses to help answer any questions you may have in the future.
 
   
Following this introduction is a summary of the major features and options of
Portfolio Director 2. It is intended to provide you with a brief overview of
those sections discussed in more detail in this prospectus.

(4) For these Funds the Total Separate Account Fee equals the VALIC Separate
    Account A mortality and expense risk fee plus the administration and
    distribution fee reduced by the Separate Account Expense Reimbursement.
    Pursuant to the Separate Account Expense Reimbursement the Company's charges

    underlying Fund and/or its affiliate for administrative and shareholder
    services provided by the Company. See "Fees and Charges -- Separate Account
    Expense Reimbursement" in this prospectus for more information.

    service or distribution fees to the Company: American Century (0.21%),
    Founders (0.25%), Neuberger Berman (0.25%), Putnam (0.25%), Scudder (0.25%)
    and Templeton Foreign Fund -- Class A (0.25%) With respect to American

(5) For these Funds the Total Separate Account Fee equals the VALIC Separate
    Account A mortality and expense risk fee plus the administration and
    distribution fee reduced by the Separate Account Expense Reimbursement. The
    Separate Account Expense Reimbursement reflects a voluntary expense
    reimbursement made by the Company directly to the Division, which may be
    terminated by the Company at any time without notice.

    objectives and policies and invests in the same portfolio as Neuberger
    Berman Guardian Fund ("Fund"). Both the Fund and the Trust are managed by
    Neuberger Berman Management Inc. ("NB"). NB voluntarily bears certain
    expenses of the Trust so that the Trust's expense ratio per annum will not
    exceed the expense ratio per annum of the Fund by more than 0.10% of the
    Trust's average daily net assets. This arrangement can be terminated on
    sixty days' notice. For this Fund, MANAGEMENT FEES include administration
    expenses. For the Trust's 1998 fiscal year, NB did not bear any expenses.

(1)  Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of Bankers Trust Corporation. On November 30, 1998,
     Bankers Trust Corporation entered into an Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
     Corporation and all of its subsidiaries would merge with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a
     major global banking institution that is engaged in a wide range of financial services, including retail and commercial
     banking, investment banking and insurance. The merger is contingent upon various regulatory approvals. On April 20, 1999,
     the AGSPC Fund's Board of Directors approved a new investment sub-advisory agreement with Bankers Trust Company, subject to
     shareholder approval. If the merger is approved and completed, Deutsche Bank AG, as the Sub-Adviser's new parent company,
     will control the operations of the Sub-Adviser. Bankers Trust believes that, under this new arrangement, the services
     provided to the Fund will be maintained at their current level.

A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
    
 
INTEREST GUARANTEED DEATH
BENEFIT
Portfolio Director 2 offers a death benefit with an interest guarantee when
death occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director 2 offers a tax-free loan provision for tax-qualified
contracts that gives you access to your money in either of the Fixed Account
Options, subject to a minimum loan amount of $1,000. The availability of loans
is subject to government regulations, as well as your employer's plan
provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e. loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
There is no charge to transfer the money in your account among Portfolio
Director 2's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you have withdrawn. The second amount is
5% of the contributions you made to your account during the last 60 months.
 
Withdrawals are always subject to your plan provisions and federal tax
restrictions, which generally include a tax penalty on withdrawals made prior to
age 59 1/2.
 
PREMIUM TAX CHARGE
   
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
    
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
aggregate annualized rate of 1.00% to 1.25% on the average daily net asset value
of VALIC Separate Account A. Reductions in the mortality and expense risk fee
and administration and distribution fee may be available for plan types meeting
certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.
 
SEPARATE ACCOUNT
EXPENSE REIMBURSEMENT
   
The Company will reimburse to certain Divisions any fees it receives from the
Mutual Fund or its affiliate or distributor for providing the Mutual Fund
administrative and shareholder services. In addition, the Company currently
reimburses certain Divisions a portion of the Company's administration and
distribution fee for providing Variable Account Options. Such reimbursement
arrangements are voluntary. For more information as to which Variable Account
Options have a Separate Account Expense Reimbursement see the Fee Table.

When you withdraw your money, you can select from several payout options: a

withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.

Financial statements of VALIC Separate Account A are included in the Statement
of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
Contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

ABOUT PORTFOLIO DIRECTOR 2
 
Portfolio Director 2 was developed to help you save money for your retirement.
It offers you a combination of fixed and variable investment options that you
can invest in to help you reach your retirement savings goals. Your
contributions to Portfolio Director 2 can come from different sources, like
payroll deductions or money transfers. Your retirement savings process with
Portfolio Director 2 will involve two stages: the Purchase Period; and the
Payout Period. The first is when you make contributions into Portfolio Director
2 called "Purchase Payments." The second, is when you receive your retirement
payouts. For more information, see "Purchase Period" and the "Payout Period" in
this prospectus.
 
You may choose, depending upon your retirement savings goals, your personal risk
tolerances, and your retirement plan, to invest in the Fixed Account Options
and/or the Variable Account Options described in this prospectus. When you
decide to retire, or otherwise withdraw your money, you can select from a wide
array of payout options including both fixed and variable payments. In addition,

ABOUT VALIC SEPARATE ACCOUNT A
 
When you direct money to Portfolio Director 2's Variable Account Options, you
will be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director 2. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account.
VALIC Separate Account A is made up of what we call "Divisions." Eighteen
Divisions are available and represent the Variable Account Options in Portfolio
Director 2. Each of these Divisions invests in a different Mutual Fund made
available through Portfolio Director 2. For example, Division Ten represents and
invests in the Stock Index Fund. The earnings (or losses) of each Division are
credited to (or charged against) the assets of that Division, and do not affect
the performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25, 1979 under Texas insurance law
to allow you to be able to invest in a number of Variable Account Options
available in Portfolio Director 2. VALIC Separate Account A is registered with
the Securities and Exchange Commission (SEC) as a unit investment trust under
the Investment Company Act of 1940 ("Act"). Units of interest in VALIC Separate
Account A are registered as securities under the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director 2, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director 2, the
Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director 2 be held exclusively for the benefit of the
contract owner, participants, annuitants, and beneficiaries of Portfolio
Director 2. When we discuss performance information in this prospectus, we mean
the performance of a VALIC Separate Account A Division.

SUMMARY OF FUNDS
 
   
A brief summary of the investment objectives of each Mutual Fund is shown below.
In addition to the investment objectives, the Account Value of an assumed
$10,000 investment in each of the Divisions is shown in both table and graph
form as well as the Standard Average Annual Total Return for a 1, 3, 5 and 10
year period or since inception, if available. If Standard Average Annual Return
for a Division is not available for a stated period, we may show the Standard
Average Annual Return since Division inception. The performance information in
the tables and graphs will reflect a deduction for separate account fees
(mortality and expense risk fees plus administration and distribution fees minus
any applicable reimbursements) and underlying fund charges. They will not
reflect any deduction for account maintenance fees, surrender charges and
premium taxes. These charges would further reduce your return. The Account
Values shown in the graphs reflect Separate Account performance based on the
performance of the underlying Fund for the last 10 fiscal years or, since
inception of the underlying Fund if for less than 10 years. The returns shown in
the tables reflect for the AGSPC Funds actual historical performance of the
related Separate Account Divisions. The returns shown in the tables for the
other Funds (Divisions 21-32) reflect actual historical performance of the
related Separate Account Divisions since inception of each Division (July 1,
1996) and hypothetical performance for periods prior to July 1, 1996.
Hypothetical performance is based on the actual performance of the underlying
Fund reduced by Separate Account fees that would have been incurred during the
hypothetical period. Investment return and principal value will fluctuate with
market conditions, and for foreign investments, currencies and the economic and
political climates of the countries where investments are made. Past performance
cannot predict or guarantee future results.
    
 
   
The Standard Average Annual Total Return figures show the average percentage
change in the value of an investment in a Division from the beginning to the end
of the historical

periodsshown below. The results shown are after all charges and fees have been
applied against the Division. This will include account maintenance fees and
surrender charges that would have been deducted if you surrendered Portfolio
Director 2 at the end of the specified period. Premium taxes are not deducted.
This information is calculated for each Division based on how an initial
investment of $1,000 performed at the end of the specified periods shown.
    
 
For more information about how these returns were calculated including a
statement of the charges reflected and tables showing historical performance
information see "How to Review Investment Performance of Separate Account
Divisions" in this prospectus.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director 2 account is surrendered before the Payout Period. The
amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director 2 was purchased.
 
PURCHASE PAYMENTS
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account.
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>

     Contract Type       Payment     Payment

Single Payment           $1,000         -0-
</TABLE>
 
   
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
    
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
   
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments within 5 business days if the requested information is not
  provided, unless you otherwise so specify.
    
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under those circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment
 
  in an "Employer-Directed" account invested in our Money Market Division
  Option. You may not transfer these amounts until VALIC has received a
  completed application or enrollment form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  Money Market Division. We will send you follow-up letters requesting the
  information necessary to complete the application, including your allocation
  instructions. Unless a completed application or enrollment form is received by
  us within 105 days of establishment of your starter account, the account
  balance, including earnings, will be returned to your employer. We are not
  responsible for any adverse tax consequences to you that may result from the
  return of your employer's contributions.
 
PURCHASE UNITS
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
The Purchase Unit value for a Division is calculated as shown below:
Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income and capital gains and losses (whether
  realized or unrealized) on that day from the assets attributable to the
  Division.
/ (DIVIDED BY)
  The value of the Division for the immediately preceding day on which the
  values are calculated.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director 2.
 
   
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.
    
For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.

We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the Exchange is open.
    
Step 2: Calculate net investment rate for any day as follows:
 
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
 
  Purchase Unit Value for that day.

  Net Investment Rate (as calculated in Step 2) plus 1.00.
 
CHOOSING INVESTMENT OPTIONS
 
   
There are 20 investment options offered in Portfolio Director 2. This includes 2
Fixed Account Options and 18 Variable Account Options. Unless provided
otherwise, you
may select and combine up to 7 of the 20 options. The Funds that underlie the
Variable Account Options are registered as investment companies under and are
subject to regulation of the Act. The Fixed Account Options are not subject to
regulation under the Act and are not required to be registered under the
Securities Act of 1933. As a result, the SEC has not reviewed data in this
prospectus that relates to the Fixed Account Options. However, federal
securities law does require such data to be accurate and complete.
    
 
FIXED ACCOUNT OPTIONS
 
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in "Summary" appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed Account Options
= (EQUALS)
  All Purchase Payments made to the Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable Account Options to the Fixed
  Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn from Fixed Account Options
  (including applicable fees and charges)
 
VARIABLE ACCOUNT OPTIONS
   
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. A complete discussion of each of the Variable Account Options may be
found in the "Variable Account Options" section in this prospectus. Based upon a
Variable Account Option's Purchase Unit Value your account will be credited with
the applicable number of Purchase Units. The Purchase Unit Value of each
Variable Account Option will change daily depending upon the investment
performance of the underlying fund (which may be positive or negative) and the
deduction of VALIC Separate Account A charges. See the "Fees and Charges"
section in this prospectus. Because Purchase Unit Values change daily, the
number of Purchase Units your account will be credited with for subsequent
Purchase Payments will vary. Each Variable Account Option bears its own
investment risk. Therefore, the value of your account may be worth more or less
at retirement or withdrawal.
    
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director 2 account has been surrendered. The
value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
   
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any
such account closure will be subject to applicable distribution restrictions
under the Contract and/or under your employer's plan.

TRANSFERS BETWEEN INVESTMENT OPTIONS
- --------------------------------------------------------------------------------
 
You may transfer all or part of your Account Value between the various Fixed
Account and Variable Account Options in Portfolio Director 2 without a charge.
Transfer instructions may be made either in writing or by telephone as discussed
below. Transfers may be made during the Purchase Period or during the Payout
Period. We reserve the right to limit transfers as discussed below. Your
employer's plan may also limit your rights to transfer.
 
DURING THE PURCHASE PERIOD
During the Purchase Period, transfers may be made between Portfolio Director 2's
Fixed Account Options and Variable Account Options.
 
We currently permit transfers between Variable Account Options or from Variable
Account Options to Fixed Account Options, at any time. We may, however, limit
the number of transfers you can make.
 
Transfers are also permitted from the Fixed Account Options subject to the

COMMUNICATING TRANSFER OR
REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director, should be
sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
   
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
    
 
- - The next date values are calculated.

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director 2, you may be subject to six basic types of
fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director 2 is issued to certain types of plans which are expected to result in
lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
   
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
    
 
   
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is actually withdrawn. We
consider all Purchase Payments to be withdrawn before earnings are withdrawn.
    
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
 
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

  of a Social Security Administration determination or a doctor's verification;
  or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director 2 is issued
to certain types of plans which are expected to result in lower costs to VALIC.
To learn more about how we determine if a surrender charge may be reduced or
waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
   
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
    
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an annualized rate of 1.00% to 1.25% on the average daily net asset value of
VALIC Separate Account A. The exact rate depends on the Variable Account Option
selected. This charge is guaranteed and cannot be increased by the Company. The
mortality and expense risk fee is to compensate the Company for assuming
mortality and expense risks under Portfolio Director. The mortality risk that
the Company assumes is the obligation to provide payments during the Payout
Period for your life no matter how long that might be. In addition, the Company
assumes the obligation to pay during the Purchase Period an interest guaranteed
death benefit. For more information about the interest guaranteed death benefit
see the "Death Benefit" section of this prospectus. The expense risk is our
obligation to cover the cost of issuing and administering Portfolio Director 2,
no matter how large the cost may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing (including but not limited to
enrollment, participant communication and education).
 
For more information about the mortality and expense risk fee and administration
and distribution fee, see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGES
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to its investment adviser. These
charges and other Fund charges and expenses are fully described in the
prospectuses for the Funds. These charges indirectly cost you because they lower
your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.
 
REDUCTION OR WAIVER OF ACCOUNT
MAINTENANCE FEE, SURRENDER,
MORTALITY AND EXPENSE RISK FEE OR ADMINISTRATION AND DISTRIBUTION FEE CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender charges, mortality and expense risk fee or administration and
distribution fee for Portfolio Director 2 may be reduced or waived. We may
reduce or waive these fees and charges if we determine that your retirement
program will allow us to reduce or eliminate administrative or sales expenses
that we usually incur for retirement programs. There are a number of factors we
will review in determining whether your retirement program will
 
                                                                              27
<PAGE>   307
 
- --------------------------------------------------------------------------------
 
allow us to reduce or eliminate these administrative or sales expenses:
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
  We review the following additional factors to determine whether we can reduce
  or waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
  We review the following additional factors to determine whether we can reduce
  or waive the mortality and expense risk fee or administration and distribution
  fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
  We will only do this if permitted by this Contract and by VALIC guidelines in
  effect at the time. In no event will the reduction or waiver of fees and
  charges be permitted where the reduction or waiver will unfairly discriminate
  against any person.
 
  SEPARATE ACCOUNT EXPENSE
  REIMBURSEMENT
 
  Some of the Mutual Funds or their affiliates may have an agreement with the
  Company to pay the Company for certain administrative and shareholder services
  it provides to the underlying Fund. The Company will reduce its charges to the
  Division investing in that Fund by the full amount of any of these payments it
  receives. In addition, the Company currently reimburses certain Divisions a
  portion of the Company's administration and distribution fee. Such
  reimbursement arrangements are voluntary. See the Fee Table in this prospectus
  for an identification of those Funds for which a reimbursement applies.

<PAGE>   308
 
PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
(1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
   
With a Variable Payout, you may select from your existing Variable Account
Options. Your payments will vary accordingly. This is due to the varying
investment results that will be experienced by each of the Variable Account
Options you selected. The Payout Unit Value is calculated just like the Purchase
Unit Value for each Variable Account Option except that the Payout Unit Value
includes a factor for the Assumed Investment Rate you select. For additional
information on how Payout Payments and Payout Unit Values are calculated, see
the Statement of Additional Information.
    
 
   
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the Variable Account Option is lower than your
Assumed Investment Rate, your next payment will be less than your first payment.
    
 
COMBINATION FIXED AND VARIABLE
PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
   
Up to seven Variable Account Options may be chosen, or up to six Variable
Account Options if the Fixed Payout is chosen.
    
 
PAYOUT DATE
The Payout Date is the date elected by you on which your payout (annuity)
payments will start. The date elected must be the first of any month provided 30
days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              29
<PAGE>   309
- --------------------------------------------------------------------------------
 
  - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
    lifetime. Upon your death, your beneficiary will receive a lump sum payment
    equal to the remaining Annuity Value.
 
  - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
    lifetime of you and your beneficiary. Upon the death of one, payments
    continue during the lifetime of the survivor. This option is designed
    primarily for couples who require maximum possible variable payouts during
    their joint lives and are not concerned with providing for beneficiaries at
    death of the last survivor. For example, it would be possible under this
    option for the Joint Annuitants to receive only one payment if both
    Annuitants died prior to the date of the second payment, or for the Joint
    Annuitants to receive only one payment and the surviving Annuitant to
    receive only one payment if one Annuitant died prior to the date of the
    second payment and the surviving Annuitant dies prior to the date of the
    third payment.
 
  - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
    number of years between five and thirty. Upon your death, payments will
    continue to your beneficiary until the designated period is completed.
 
ENHANCEMENTS TO PAYOUT OPTIONS
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. The Joint and Survivor
Life Option may be available with a one to twenty year guaranteed period option.
Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
   
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
    
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option, and
 
   
  - The payments will be guaranteed for a 10 year period,
    
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
   
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis, and
    
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
   
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or plan.

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.
 
AMOUNT THAT MAY BE SURRENDERED
The amount that may be surrendered at any time can be determined as follows:
 
<TABLE>
<S>                    <C>               <C>
                                               Your
                                              Account
       Allowed                               Value(1)
      Surrender           = (EQUALS)         - (MINUS)
        Value                             Any Applicable
                                             Surrender
                                              Charge
</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
   
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See your current Fund(s)' prospectuses
for a discussion of the reasons why the redemption of shares may be suspended or
postponed.
    
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
 
Under the FLORIDA STATE OPTIONAL RETIREMENT PROGRAM, no surrender or partial
surrender of Purchase Payments made by the employer will be allowed except for
termination of employment, retirement or death. Benefit payments based on
payments from the employer may not be paid in a lump sum or for a period
certain, but must be paid under a life contingency option, except for:
 
  - death benefits; and
 
  - certain small amounts approved by the State of Florida.
 
   
Under the LOUISIANA OPTIONAL RETIREMENT PLAN retirement benefits must be paid in
the form of a lifetime income, and except for death benefits, single sum
surrenders and partial surrenders out of the plan are not permitted.
    
 
   
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
    
 
PARTIAL SURRENDERS
   
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Options first unless otherwise specified by you.
    
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director 2. There will be no surrender charge for withdrawals using this method,
which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
revoked, a systematic withdrawal may not be
 
                                                                              31
<PAGE>   311
- --------------------------------------------------------------------------------
 
elected again. No more than one systematic withdrawal election may be in effect
at any one time. We reserve the right to discontinue any or all systematic
withdrawals or to change its terms, at any time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW. There will be no surrender charge on
a minimum distribution required by federal tax law (known as No Charge Minimum
Distribution), if the withdrawal:
 
  - Is made payable to you; and
 
  - Does not exceed the amount required under federal tax law as determined by
    the values in your Portfolio Director 2 Contract and VALIC.
 
This contract feature will not be available in any year that an amount has been
withdrawn under the no charge systematic withdrawal method. See "Federal Tax
Matters" in this prospectus and in the Statement of Additional Information for
more information about required distributions imposed by tax law.
 
For an explanation of possible adverse tax consequences of a surrender, see
"Federal Tax Matters" in this prospectus and in the Statement of Additional
Information.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
   
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director 2. These other contracts are listed below. We
will allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director 2. This exchange privilege will be available
only to other contracts purchased through your employer-sponsored retirement
plan and for which we have not yet started making payments under a Payout
Option. If you elect to exercise one of these exchange offers, you should
contact any of our Regional Offices at the addresses shown in the back of this
prospectus. An exchange may require the issuance of a Contract or may be subject
to any other requirements that the Company may impose.
    
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
   
  - Exchanges from Portfolio Director 2 to contract forms other than Portfolio
    Director Plus are not permitted.
    
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director 2. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director 2. For example, you
will be subject to the rules concerning transfers among investment options as
stated in the Transfers Between Investment Options section in this prospectus.
We may, at our option, waive any transfer restrictions for a stated period of
time. If we waive these transfer restrictions, you will be allowed to exchange
to any investment option available in Portfolio Director 2.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director 2.
 
SURRENDER CHARGES
 
We will generally not impose nor waive existing surrender charges as a result of
your electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director 2 will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director 2, the
contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director 2 will be the same date as the other contract, but no
earlier than January 1, 1982. (The effect of this is to potentially shorten the
charge period for Purchase Payments subsequently made to Portfolio Director 2.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director 2 for purposes of calculating the surrender charge. The effective dates
of these Purchase Payments will also be retained for surrender charge purposes.
 
The Portfolio Director 2 surrender charge is calculated assuming the most recent
Purchase Payments are removed first. This policy may cause exchanged funds to be
accessible only after charges are imposed.

AGENTS' AND MANAGERS' RETIREMENT PLAN
EXCHANGE OFFER
 
General. All eligible agents and managers of the Company are allowed to
participate in the Company's Agents' and Managers' Retirement Plan ("Plan"). We
grant to participants in the Plan the right to effect a voluntary exchange of
their units of interest under the SA-1 Contracts, Independence Plus Contracts
and Portfolio Director for the equivalent units of interest in Portfolio
Director 2.
 
Agents and managers of VALIC who enter into the voluntary exchange will not
incur under Portfolio Director 2 any surrender charges or account maintenance
fees. Other individuals who may exchange to Portfolio Director 2 from SA-1,
Independence Plus or Portfolio Director Contracts may have surrender charges and
account maintenance fees imposed under Portfolio Director 2. All other
provisions with regard to exchange offers referenced in the section entitled
"Exchange Offers" will apply to the Agents' and Managers' Retirement Plan
Exchange Offer.
 
Pursuant to this voluntary exchange offer, participants in the Plan will have
three options to choose from. As to the funding vehicle for their purchase
payment plan, the participant may choose to:
 
  - Remain in the SA-1 Contract, Independence Plus Contract or Portfolio
    Director.
 
  - Leave current assets in the SA-1 Contract, Independence Plus or Portfolio
    Director and direct future Purchase Payments to Portfolio Director 2; or
 
  - Transfer all current assets and future Purchase Payments to Portfolio
    Director 2.
 
If the participant chooses to remain in either the SA-1 Contract, Independence
Plus Contract or Portfolio Director, future Purchase Payments and current assets
will be controlled by the provisions
 
 34
<PAGE>   314
 
- --------------------------------------------------------------------------------
 
of the SA-1 Contract, Independence Plus Contract or Portfolio Director,
respectively. If the participant chooses to leave current assets in the SA-1
Contract, the Independence Plus Contract or Portfolio Director and direct future
Purchase Payments to Portfolio Director 2, the current assets will be controlled
by the provisions of the SA-1 Contract, the Independence Plus Contract or
Portfolio Director, respectively. The future Purchase Payments will be
controlled by the terms of Portfolio Director 2 subject to the exception that
surrender charges and account maintenance fees will not be imposed under
Portfolio Director 2. If the participant chooses to transfer all current assets
and future Purchase Payments to Portfolio Director 2, such current assets and
future Purchase Payments will be controlled by the provisions of Portfolio
Director 2 subject to the exception that surrender charges and account
maintenance fees will not be imposed under Portfolio Director 2.
 
   
Once a participant transfers assets and future Purchase Payments to Portfolio
Director 2 the participant will not be permitted to exchange back to the SA-1
Contract or Independence Plus Contract. See "Exchange Offer for Portfolio
Director and Portfolio Director 2" in this prospectus. If a participant chooses
to transfer future Purchase Payments but not current assets to Portfolio
Director 2, the participant will be allowed at a later date to transfer the
current assets to Portfolio Director 2. For a complete analysis of the
differences between the SA-1 contract, the Independence Plus Contract or
Portfolio Director and Portfolio Director 2, you should refer to the Statement
of Additional Information and the form of the contract or certificate for its
terms and conditions.

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director 2 will pay death benefits during either the Purchase Period
or the Payout Period. How these death benefits will be paid are discussed below.
The death benefit provisions in Portfolio Director 2 may vary from state to
state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
- - In a lump sum; or
 
- - In the form of an annuity under any of the Payout Options stated in the Payout
  Period section of this prospectus subject to the restrictions of that Payout
  Option.
 
   
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
    
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
- - In full within 5 years after the Annuitant's death; or
 
- - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
   
  - An annuity for a designated period, not exceeding the Beneficiary's life
    expectancy.
    
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director 2.
 
SPECIAL INFORMATION FOR INDIVIDUAL
NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the Annuitant's death. However, the Contract
will be transferred to the Contingent Owner,
if any, or to the Contract Owner's estate. Such transfers will be considered a
taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:
Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Fixed Account Option on date
  proof of death Is received by VALIC
  OR
  100% of Purchase Payments placed
  in Fixed Account Option
- - (MINUS)
  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
</TABLE>
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Variable Account Option on date
  proof of death is received by VALIC
  OR
  100% of Purchase Payments placed in
  Variable Account Options
- - (MINUS)
  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option
+ (PLUS)
  Interest at an annual rate of 3%
</TABLE>
 
Step 3: Add step 1 + 2 = Death Benefit
 
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
STANDARD DEATH BENEFIT
 
The standard death benefit is payable if death occurs on or after age 70.
 
BENEFICIARY -- the person
designated to receive Payout
Payments upon the death of
an Annuitant.
 
ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid.
 
   
CONTRACT OWNER -- either
    
   
your employer or organization
    
   
in the case of a group
    
   
contract or the Annuitant in
    
   
the case of an individual
    
   
contract. If the contract is an
    
   
individual non-qualified type,
    
   
this is generally the Annuitant
    
   
but is not required to be.
    
   
Also, a Contingent Contract
    
   
Owner may be designated.
    
 
FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options. Currently,
the Fixed Account Options in
Portfolio Director 2 are Fixed
Account Plus and Short-Term
Fixed Account. Each option
of this type is guaranteed to
earn at least a minimum rate
of interest.
 
   
VARIABLE ACCOUNT
    
OPTIONS -- investment
options that correspond to
VALIC Separate Account A
Divisions offered by Portfolio
Director 2. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.
 
 36
<PAGE>   316
- --------------------------------------------------------------------------------
 
The Standard Death Benefit will be the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Your Account Value on the Date Proof of Death is
  Received by VALIC
  OR
  100% of Purchase Payments (to Fixed
  and/or Variable Account Options)
- -- (MINUS)
  Amount of all Prior Withdrawals, Charges
  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director 2 are described in the "Payout Period" section
of this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed

HOW TO REVIEW INVESTMENT PERFORMANCE
OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
   
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts or to the general public
before Portfolio Director 2 was first available to you. We may therefore,
advertise investment performance since the inception of the underlying Funds. In
each case, we will use the charges and fees imposed by Portfolio Director 2 in
calculating the Division's investment performance.
    
 
TYPES OF INVESTMENT PERFORMANCE
INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE
INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Standard Average Annual Total Return shows the average percentage change in the
value of an investment in the Division from the beginning to the end of a given
historical period. The results shown are after all charges and fees have been
applied against the Division. This will include account maintenance fees and
surrender charges that would have been deducted if you surrendered Portfolio
Director 2 at the end of each period shown. Premium taxes are not deducted. This
information is calculated for each Division based on how an initial assumed
payment of $1,000 performed at the end of 1, 3, 5 and 10 year periods. If
Standard Average Annual Return for a Division is not available for a stated
period, we may show the Standard Average Annual Return since Division inception.
    
 
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
 
NONSTANDARD AVERAGE ANNUAL TOTAL
RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance information of an underlying Fund
reduced by account fees for a period prior to the inception of the corresponding
Division is nonstandard performance information regardless of whether all
account fees and charges are deducted.
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director 2 will stay
in the Division beyond the time that a surrender charge would apply. It may be
calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
   
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the Division's Annual
Change in Purchase Unit Value.
 
DIVISIONS -- subaccounts of
    
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director 2. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director 2.

TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.

<PAGE>   318
- --------------------------------------------------------------------------------
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT
INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director 2 charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC Money Market Division
 
We may advertise the AGSPC Money Market Division's Current Yield and Effective
Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market Division over a given 7-day period. The Current Yield does not take
into account surrender charges, account maintenance fees or premium taxes. The
income produced over a 7 day period is then "annualized." This means we are
assuming the amount of income produced during the 7-day period will continue to
be produced each week for an entire year. The annualized amount is shown as a
percentage of the investment. The annualized 7-day Current Yield for the last 7
days ended December 31, 1998 was 3.64%.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause the Effective Yield to be higher than the Current
Yield. The annualized 7-day Effective Yield for the last 7 days ended December
31, 1998 was 3.71%.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET DIVISION
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market Division. The yield for each of these Divisions will be
determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION:
 
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
   
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate Account A
Division is printed in the eight tables below.
    
 
The information presented does not reflect the advantage under Portfolio
Director 2 of deferring federal income tax on increases in Account Value due to
earnings attributable to Purchase Payments (see "Federal Tax Matters" in the
prospectus and in the Statement of Additional Information.) The information
presented also does not reflect the advantage under Qualified Contracts of
deferring federal income tax on Purchase Payments.
 
The performance results shown in the following tables are not an estimate or
guarantee of future investment performance, and do not represent the actual
experience of amounts invested by a particular Participant.

  * The performance figures in the Table reflect the investment performance for
    the Funds for the stated periods and should not be used to infer that future
    performance will be the same.
    
 
   
 ** For the year in which the underlying Fund commenced operations, less than a
    full year's performance has been reflected, which is not annualized.
    
 
   
*** The performance figures in the Table do not take into account the Separate
    Account Reimbursement made by the Company directly to those Divisions. If
    such reimbursements were included, the performance figures for the Divisions
    would be higher.
    
 
   
(1) For periods prior to 1996, the Annual and Cumulative Change in Purchase Unit
    Value figures are based on the average and cumulative changes in Purchase
    Unit Value for a stated period in a corresponding Division of Separate
    Account A for a different Contract offered by the Company and have been
    restated to take into account the fees and charges under Portfolio Director
    2 other than the surrender charge and account maintenance fee. The Contracts
    offered by this prospectus became available for purchase on July 1, 1996.

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director 2
was issued in connection with a nonqualified and unfunded deferred compensation
plan.
 
DETERMINATION OF FUND SHARES
ATTRIBUTABLE TO YOUR ACCOUNT
 
DURING PURCHASE PERIOD
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
DURING PAYOUT PERIOD OR AFTER A DEATH
BENEFIT HAS BEEN PAID
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director 2
may have a number of shareholders including VALIC Separate Account A, VALIC
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies and public shareholders.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
   
VALIC Separate Account A will vote the shares of the Funds it holds based on,
and in the same proportion as, the voting instructions received from
participants in VALIC Separate Account A.
    
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.
 
VALIC SEPARATE
ACCOUNT A -- a segregated

FEDERAL TAX MATTERS
- --------------------------------------------------------------------------------
 
Portfolio Director 2 provides tax-deferred accumulation over time, but is
subject to federal income and excise taxes, mentioned briefly below. You should
refer to the Statement of Additional Information for further details. Section
references are to the Internal Revenue Code ("Code"). We do not attempt to
describe any potential estate or gift tax, or any applicable state, local or
foreign tax law other than possible premium taxes mentioned under "Premium Tax
Charge." Remember that future legislation could modify the rules discussed
below, and always consult your personal tax adviser regarding how the current
rules apply to your specific situation.
 
TYPE OF PLANS
 
   
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program or 408(b) IRA, as a Section 408(b)
Individual Retirement Annuity ("IRA"), or is instead a nonqualified Contract.
Portfolio Director 2 is used under the following types of retirement
arrangements:
    
 
  - Section 403(b) annuities for employees
     of public schools and
     Section 501(c)(3) tax-exempt
     organizations;
 
  - Section 401(a) and 403(a) qualified plans of for-profit employers and other
    employers (including self-employed individuals);
 
   
  - Section 408(b) IRAs;
    
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
   
  - Section 408(k) SEPs;
    
 
  - Section 408(p) SIMPLE retirement accounts.
 
   
The foregoing Contracts are "Qualified Contracts." Certain series of Portfolio
Director 2 may also be available through a nondeductible Section 408A "Roth"
individual retirement annuity ("Roth IRA").
    
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
   
In addition, Portfolio Director 2 is also available through "Non-Qualified
Contracts" to the extent acquired by "Non-Natural Persons." Such Non-Qualified
Contracts generally include unfunded, nonqualified deferred compensation plans
of corporate employers, as well as individual annuity contracts issued to
individuals outside of the context of any formal employer or employee retirement
plan or arrangement. Non-Qualified Contracts generally may invest only in mutual
funds which are not available to the general public outside of annuity contracts
or life insurance contracts.
    
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director 2 can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Qualified Contracts receive deferral of tax on
the inside build-up of earnings on invested Purchase Payments, until a
distribution occurs. See the Statement of Additional Information for special
rules, including those applicable to taxable, non-natural owners of
Non-Qualified Contracts.
 
   
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
    
 
Distributions are taxed differently depending on the program through which
Portfolio Director 2 is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
   
Amounts subject to income tax may also incur excise or penalty taxes, under the
circumstances described in the Statement of Additional Information. Generally,
they would also be subject to some form of federal income tax withholding unless
rolled into another tax-deferred vehicle. Required withholding will vary
according to type of program, type of payment and your tax status. In addition,
amounts received
    
 
 48
<PAGE>   328
- --------------------------------------------------------------------------------
 
under all Contracts may be subject to state income tax withholding requirements.
 
   
It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if purchase payments under the contract are invested in
publicly available mutual funds. In a ruling published in 1981, the Internal
Revenue Service ("IRS") had taken the position that, where purchase payments
under a variable annuity contract are invested in publicly available mutual
funds, the contract owner should be treated as the owner of the mutual fund
shares, and deferred tax treatment under the contract should not be available.
In the opinion of VALIC and its tax counsel, the 1981 ruling has been superseded
by subsequent legislation (Code Section 817(h)) which specifically exempts these
Qualified Contracts, and the IRS has no viable legal basis or reason to apply
the theory of the 1981 ruling to these Qualified Contracts under current law.
Although VALIC can provide no assurance that the IRS will not challenge the
deferred tax treatment of these Qualified Contracts under the theory of the 1981
ruling, VALIC and its tax counsel believe that Contract owners would prevail if
such a challenge were made.
    
 
   
It is also the opinion of VALIC and its tax counsel that for each other type of
Qualified Contract an independent exemption provides tax deferral regardless of
how ownership of the Mutual Fund shares might be imputed for federal income tax
purposes.
    
 
   
Investment earnings on contributions to Non-Qualified Contracts which are not
owned by natural persons will be taxed currently to the owner and such contracts
will not be treated as annuities for federal income tax purposes.
    
 
EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director 2 Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
 
   
                        THE POWER OF TAX-DEFERRED GROWTH
    
                                  [BAR GRAPH]
 
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. The deduction of
fees and charges for both tax-deferred plans is reflected in the chart. Variable
options incur mortality and expense risk fee and administration and distribution
fee charges (1% - 1.25%) and may also incur account maintenance fees ($3.75 per
quarter) and surrender charges (5% of the lesser of all contributions received
during the last 60 months or the amount withdrawn). The dotted lines represent
the amounts remaining after withdrawal and payment of taxes and any surrender
charge. An additional 10% tax penalty may apply to withdrawals before age
59 1/2. This information is for illustrative purposes only and is not a
guarantee of future return.
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.
 
To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE
REDUCED BY THE IMPACT OF INCOME TAXES UPON WITHDRAWAL. The yield will vary
depending upon the timing of withdrawals. The previous chart represents (without
factoring in
 
                                                                              49

- --------------------------------------------------------------------------------
 
fees and charges) after-tax amounts that would be received.
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

</TABLE>
 
This chart assumes a 28% federal income tax rate. The $700 which is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800 while the full $2,500 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a tax-
qualified retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-qualified retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
YEAR 2000 RISKS
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
  - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
    Problem. This plan includes the five steps that we believe are essential to
    Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or
    replace systems that are not Year 2000 ready; (4) test systems to prove that
    they will work correctly into the Year 2000; and (5) return the systems to
    operations. As of December 31, 1998, we have substantially completed all
    steps with respect to our critical systems.
    
 
   
  - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that
    must also be Year 2000 ready. Third parties are companies that provide
    certain services to VALIC. Third parties are different from internal systems
    in that VALIC has less, or no, control over their Year 2000 readiness. VALIC
    has developed a plan to review and try to lessen the Year 2000 risks of
    third parties. As of December 31, 1998, VALIC has substantially completed
    its review of third party Year 2000 risks. VALIC intends to test third party
    Year 2000 readiness throughout 1999.
    
 
   
  - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
    associated with the Year 2000 Problem. The contingency plans for third party
    relationships include the following activities: (1) evaluate the
    consequences of any failures associated with the Year 2000 Problem; (2)
    determine the chance of a Year 2000-related failure for systems that have a
    high chance of failing; (3) develop an action plan to complete contingency
    plans for those systems that rank high in both impact of failure and chance
    of failure; and (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.

PROSPECTUS
 
   
The Variable Annuity Life Insurance Company ("VALIC") offers certain series of
Portfolio Director 2 that consist of group and individual variable annuity
contracts (the "Contracts") to Participants in certain employer sponsored
retirement plans. Portfolio Director 2 Series 2.1.20 to 2.12.20 consists of
group variable annuity contracts that are offered by VALIC to Participants in
certain employer sponsored retirement plans as well as for certain after-tax
arrangements that are not part of an employer's plan. Portfolio Director 2 may
be available to you when you participate in a retirement program that qualifies
for deferral of federal income taxes. Non-qualified contracts are also available
for certain employer plans only.
    
 
   
Portfolio Director 2 permits you to invest in and receive retirement benefits in
up to 2 Fixed Account Options and/or an array of up to 18 Variable Account
Options. If your contract is part of your employer's retirement program, that
program will describe which Variable Account Options are available to you. If
your contract is a tax-deferred nonqualified annuity that is not part of your
employer's retirement plan, those Variable Account Options that are invested in
Mutual Funds available to the public outside of annuity contracts, life
insurance contracts, or certain employer-sponsored retirement plans will not be
available within your contract. Each of these investment options is explained
more fully in this prospectus. Here is a list of these investment options:
    
 
TWO FIXED ACCOUNT OPTIONS:    Fixed Account Plus
                              Short-Term Fixed Account

This prospectus is being given to you to help you make decisions for selecting
various investment options and benefits to plan and save for your retirement. It
is intended to provide you with information about VALIC, Portfolio Director 2,
and saving for your retirement.
 
The purpose of Variable Account Options and Variable Payout Options is to
provide you investment returns which are greater than the effects of inflation.
We cannot, however, guarantee that this purpose will be achieved.

Separate Account A are offered. Portfolio Director 2 will allow you to
accumulate retirement dollars in Fixed Account Options and/or Variable Account
Options. This prospectus describes only the variable aspects of Portfolio
Director 2 except where the Fixed Account Options are specifically mentioned.
 
For specific information about the Variable Account Options, you should refer to
the mutual fund prospectuses you have been given with this document. You should
keep these prospectuses to help answer any questions you may have in the future.

(2) Reductions in the surrender charge and the account maintenance fee are
    available if certain conditions are met. See "Reduction or Waiver of Account
    Maintenance Fee, Surrender, Mortality and Expense Risk Fee or Administration
    and Distribution Fee Charges" and "Exceptions to Surrender Charge" in this
    prospectus.
    
 
   
(3) The mortality and expense risk fee and administration and distribution fee
    reflected in the Fee Table is deducted during the Purchase Period. The
    mortality and expense risk fee and administration and distribution fee
    deducted during the Payout Period is computed at an annualized rate of 1.00%
    to 1.25%, depending upon the Variable Account Option selected.
    
 
   
(4) For these Funds the Total Separate Account Fee equals the VALIC Separate
    Account A mortality and expense risk fee plus the administration and
    distribution fee reduced by the Separate Account Expense Reimbursement.
    Pursuant to the Separate Account Expense Reimbursement the Company's charges
    to these Divisions are reduced by an amount equal to payments from the
    underlying Fund and/or its affiliate for administrative and shareholder
    services provided by the Company. See "Fees and Charges -- Separate Account
    Expense Reimbursement" in this prospectus for more information.
    
 
   
    The following Funds and/or their affiliates pay administrative, shareholder
    service or distribution fees to the Company: American Century (0.21%),
    Founders (0.25%), Neuberger Berman (0.25%), Putnam (0.25%), Scudder (0.25%)
    and Templeton Foreign Fund -- Class A (0.25%). With respect to American
    Century Ultra Fund, the Fund pays fees to the Company of 0.20% on assets in
    excess of $0 but less than $75 million, and 0.25% on assets equal to or in
    excess of $75 million.
    
 
   
(5) For these Funds the Total Separate Account Fee equals the VALIC Separate
    Account mortality and expense risk fee plus the administration and
    distribution fee reduced by the Separate Account Expense Reimbursement. The
    Separate Account Expense Reimbursement reflects a voluntary expense
    reimbursement made by the Company, directly to the Division, which may be
    terminated by the Company at any time without notice.
    
 
   
(6) OTHER EXPENSES includes custody, accounting, reports to shareholders, audit,
    legal and other miscellaneous expenses. See each Fund's prospectus for a
    detailed explanation of these fees.
    
 
   
(7) Neuberger Berman Guardian Trust ("Trust") has identical investment
    objectives and policies and invests in the same portfolio as Neuberger
    Berman Guardian Fund ("Fund"). Both the Fund and the Trust are managed by
    Neuberger Berman Management Inc. ("NB"). NB voluntarily bears certain
    expenses of the Trust so that the Trust's expense ratio per annum will not
    exceed the expense ratio per annum of the Fund by more than 0.10% of the
    Trust's average daily net assets. This arrangement can be terminated on
    sixty days' notice. For this Fund, MANAGEMENT FEES include administration
    expenses. For the Trust's 1998 fiscal year, NB did not bear any expenses.

(1)  Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of Bankers Trust Corporation. On November 30, 1998,
     Bankers Trust Corporation entered into an Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
     Corporation and all of its subsidiaries would merge with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a
     major global banking institution that is engaged in a wide range of financial services, including retail and commercial
     banking, investment banking and insurance. The merger is contingent upon various regulatory approvals. On April 20, 1999,
     the AGSPC Fund's Board of Directors approved a new investment sub-advisory agreement with Bankers Trust Company, subject to
     shareholder approval. If the merger is approved and completed, Deutsche Bank AG, as the Sub-Adviser's new parent company,
     will control the operations of the Sub-Adviser. Bankers Trust believes that, under this new arrangement, the services
     provided to the Fund will be maintained at their current level.

SUMMARY -- (CONTINUED)
    
- --------------------------------------------------------------------------------
 
   
A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
    
 
INTEREST GUARANTEED DEATH
BENEFIT
Portfolio Director 2 offers a death benefit with an interest guarantee when
death occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director 2 offers a tax-free loan provision for tax-qualified
contracts that gives you access to your money in either of the Fixed Account
Options, subject to a minimum loan amount of $1,000. The availability of loans
is subject to government regulations, as well as your employer's plan
provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e. loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
There is no charge to transfer the money in your account among Portfolio
Director 2's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you have withdrawn. The second amount is
5% of the contributions you made to your account during the last 60 months.
 
Withdrawals are always subject to your plan provisions and federal tax
restrictions, which generally include a tax penalty on withdrawals made prior to
age 59 1/2.
 
PREMIUM TAX CHARGE
   
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
    
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
aggregate annualized rate of 0.80% to 1.05% during the purchase period and 1.00%
to 1.25% during the payout period on the average daily net asset value of VALIC
Separate Account A. Reductions in the mortality and expense risk fee and
administration and distribution fee may be available for plan types meeting
certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.
 
SEPARATE ACCOUNT
EXPENSE REIMBURSEMENT
   
The Company will reimburse to certain Divisions any fees it receives from the
Mutual Fund or its affiliate or distributor for providing the Mutual Fund
administrative and shareholder services. In addition, the Company currently
reimburses to certain Divisions a portion of the Company's administration and
distribution fee for providing Variable Account Options. Such reimbursement
arrangements are voluntary. For more information as to which Variable Account
Options have a Separate Account Expense Reimbursement see the Fee Table.
    
 
PAYOUT OPTIONS
When you withdraw your money, you can select from several payout options: a
lifetime annuity (which guarantees payment for as long as you live), periodic
withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.
 
FEDERAL TAX INFORMATION
Although deferred annuity contracts such as Portfolio Director 2 can be
purchased with after-tax dollars, they are primarily used in connection with
retirement programs which receive favorable tax treatment under federal law.
 
PURCHASE REQUIREMENTS
Purchase Payments may be made at any time and in any amount, subject to plan
limitations.
 
To learn more about the
INTEREST GUARANTEED DEATH
BENEFIT, refer to the section
in the prospectus entitled
"Death Benefits."
 
More information on FEES
may be found in the
prospectus under the
headings "FEES AND
CHARGES" AND "FEE TABLE."
 
For a more detailed
discussion of these income
tax provisions, see the
"FEDERAL TAX MATTERS"
section of the prospectus and
of the Statement of Additional
Information.

Financial statements of VALIC Separate Account A are included in the Statement
of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
Contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

ABOUT VALIC SEPARATE ACCOUNT A
 
When you direct money to Portfolio Director 2's Variable Account Options, you
will be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director 2. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account.
VALIC Separate Account A is made up of what we call "Divisions." Eighteen
Divisions are available and represent the Variable Account Options in Portfolio
Director 2. Each of these Divisions invests in a different Mutual Fund made
available through Portfolio Director 2. For example, Division Ten represents and
invests in the Stock Index Fund. The earnings (or losses) of each Division are
credited to (or charged against) the assets of that Division, and do not affect
the performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25, 1979 under Texas insurance law
to allow you to be able to invest in a number of Variable Account Options
available in Portfolio Director 2. VALIC Separate Account A is registered with
the Securities and Exchange Commission (SEC) as a unit investment trust under
the Investment Company Act of 1940 ("Act"). Units of interest in VALIC Separate
Account A are registered as securities under the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director 2, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director 2, the
Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director 2 be held exclusively for the benefit of the
contract owner, participants, annuitants, and beneficiaries of Portfolio
Director 2. When we discuss performance information in this prospectus, we mean
the performance of a VALIC Separate Account A Division.
 
All inquiries regarding
PORTFOLIO DIRECTOR 2

and charges to VALIC Separate Account A.

SUMMARY OF FUNDS
 
   
A brief summary of the investment objectives of each Mutual Fund is shown below.
In addition to the investment objectives, the Account Value of an assumed
$10,000 investment in each of the Divisions is shown in both table and graph
form as well as the Standard Average Annual Total Return for a 1, 3, 5 and 10
year period, if available. If Standard Average Annual Return for a Division is
not available for a stated period, we may show the Standard Average Annual
Return since Division inception. The performance information in the tables and
graphs will reflect a deduction for separate account fees (mortality and expense
risk fees plus administration and distribution fees minus any applicable
reimbursements) and underlying fund charges. They will not reflect any deduction
for account maintenance fees, surrender charges and premium taxes. These charges
would further reduce your return. The Account Values in the graphs shown reflect
Separate Account performance based on the performance of the underlying Fund for
the last 10 fiscal years or, since inception of the underlying Fund if for less
than 10 years. The returns shown in the tables reflect for the AGSPC Funds
actual historical performance of the related Separate Account Divisions. The
returns shown in the tables for the other Funds (Divisions 21-32) reflect actual
historical performance of the related Separate Account Divisions since inception
of each Division (July 1, 1996) and hypothetical performance for periods prior
to July 1, 1996. Hypothetical performance is based on the actual performance of
the underlying Fund reduced by Separate Account fees that would have been
incurred during the hypothetical period. Investment return and principal value
will fluctuate with market conditions, and for foreign investments, currencies
and the economic and political climates of the countries where investments are
made. Past performance cannot predict or guarantee future results.
    
 
   
The Standard Average Annual Total Return figures show the average percentage
change in the value of an investment in a Division from the beginning to the end
of the historical periods shown below. The results shown are after

all charges and fees have been applied against the Division. This will include
account maintenance fees and surrender charges that would have been deducted if
you surrendered Portfolio Director 2 at the end of the specified period. Premium
taxes are not deducted. This information is calculated for each Division based
on how an initial investment of $1,000 performed at the end of the specified
periods shown.

Divisions" in this prospectus.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director 2 account is surrendered before the Payout Period. The
amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director 2 was purchased.
 
PURCHASE PAYMENTS
 
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account.
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>
<CAPTION>
                         Initial    Subsequent
     Contract Type       Payment     Payment
- -----------------------  -------    ----------
<S>                      <C>        <C>
Periodic Payment         $   30        $ 30
Single Payment           $1,000         -0-
</TABLE>
 
   
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
    
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
   
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments within 5 business days if the requested information is not
  provided unless you otherwise so specify.
    
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under these circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment in an "Employer-Directed"
  account invested in our Money Market Division Option. You may not transfer
  these amounts until VALIC has received a completed application or enrollment
  form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  Money Market Division. We will send you follow-up letters requesting the
  information necessary to complete the application, including your allocation
  instructions. Unless a completed application or enrollment form is received by
  us within 105 days of establishment of your starter account, the account
  balance, including earnings, will be returned to your employer. We are not
  responsible for any adverse tax consequences to you that may result from the
  return of your employer's contributions.
 
PURCHASE UNITS
 
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
 
The Purchase Unit value for a Division is calculated as shown below:

Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income and capital gains and losses (whether
  realized or unrealized) on that day from the assets attributable to the
  Division.
/ (DIVIDED BY)
  The value of the Division for the immediately preceding day on which the
  values are calculated.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director 2.
 
   
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.
    
 
For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.
 
                                                                              23
<PAGE>   365
- --------------------------------------------------------------------------------
 
   
We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the Exchange is open.
    
Step 2: Calculate net investment rate for any day as follows:
 
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
 
  Purchase Unit Value for that day.
= (EQUALS)
  Purchase Unit Value for immediate preceding day.
X (MULTIPLIED BY)
  Net Investment Rate (as calculated in Step 2) plus 1.00.
 
Choosing Investment Options
   
There are 20 investment options offered in Portfolio Director 2. This includes 2
Fixed Account Options and 18 Variable Account Options. Unless provided
otherwise, you
may select and combine up to 7 of the 20 options. The Funds that underlie the
Variable Account Options are registered as investment companies under and are
subject to regulation of the Act. The Fixed Account Options are not subject to
regulation under the Act and are not required to be registered under the
Securities Act of 1933. As a result, the SEC has not reviewed data in this
prospectus that relates to the Fixed Account Options. However, federal
securities law does require such data to be accurate and complete.
    
 
FIXED ACCOUNT OPTIONS
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in "Summary" appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed Account Options
= (EQUALS)
  All Purchase Payments made to the Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable Account Options to the Fixed Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn from Fixed Account Options (including
  applicable fees and charges)
 
VARIABLE ACCOUNT OPTIONS
   
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. A complete discussion of each of the Variable Account Options may be
found in the "Variable Account Options" section in this prospectus. Based upon a
Variable Account Option's Purchase Unit Value your account will be credited with
the applicable number of Purchase Units. The Purchase Unit Value of each
Variable Account Option will change daily depending upon the investment
performance of the underlying fund (which may be positive or negative) and the
deduction of VALIC Separate Account A charges. See the "Fees and Charges"
section in this prospectus. Because Purchase Unit Values change daily, the
number of Purchase Units your account will be credited with for subsequent
Purchase Payments will vary. Each Variable Account Option bears its own
investment risk. Therefore, the value of your account may be worth more or less
at retirement or withdrawal.
    
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director 2 account has been surrendered. The
value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
   
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any
such account closure will be subject to applicable distribution restrictions
under the Contract and/or under your employer's plan.

TRANSFERS BETWEEN INVESTMENT OPTIONS
- --------------------------------------------------------------------------------
 
You may transfer all or part of your Account Value between the various Fixed
Account and Variable Account Options in Portfolio Director 2 without a charge.
Transfer instructions may be made either in writing or by telephone as discussed
below. Transfers may be made during the Purchase Period or during the Payout
Period. We reserve the right to limit transfers as discussed below. Your
employer's plan may also limit your rights to transfer.
 
DURING THE PURCHASE PERIOD
During the Purchase Period, transfers may be made between Portfolio Director 2's
Fixed Account Options and Variable Account Options.
 
We currently permit transfers between Variable Account Options or from Variable
Account Options to Fixed Account Options, at any time. We may, however, limit

COMMUNICATING TRANSFER OR
REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director, should be
sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
   
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
    
 
- - The next date values are calculated.

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director 2, you may be subject to six basic types of
fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director 2 is issued to certain types of plans which are expected to result in
lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
   
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
    
 
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is
actually withdrawn. We consider all Purchase Payments to be withdrawn before
earnings are withdrawn.
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
 
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

- --------------------------------------------------------------------------------
 
- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy of a Social Security Administration determination or a doctor's
  verification; or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director 2 is issued
to certain types of plans which are expected to result in lower costs to VALIC.
To learn more about how we determine if a surrender charge may be reduced or
waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
   
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
    
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an aggregate annualized rate of 0.80% to 1.05% during the Purchase Period and
1.00% to 1.25% during the Payout Period on the average daily net asset value of
VALIC Separate Account A. The exact rate depends on the Variable Account Option
selected. This charge is guaranteed and cannot be increased by the Company. The
mortality and expense risk fee is to compensate the Company for assuming
mortality and expense risks under Portfolio Director. The mortality risk that
the Company assumes is the obligation to provide payments during the Payout
Period for your life no matter how long that might be. In addition, the Company
assumes the obligation to pay during the Purchase Period an interest guaranteed
death benefit. For more information about the interest guaranteed death benefit
see the "Death Benefit" section of this prospectus. The expense risk is our
obligation to cover the cost of issuing and administering Portfolio Director 2,
no matter how large the cost may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing (including but not limited to
enrollment, participant communication and education).
 
For more information about the mortality and expense risk fee, and
administration and distribution fee see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGES
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to its investment adviser. These
charges and other Fund charges and expenses are fully described in the
prospectuses for the Funds. These charges indirectly cost you because they lower
your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.
 
                                                                              27

REDUCTION OR WAIVER OF ACCOUNT
MAINTENANCE FEE, SURRENDER,
MORTALITY AND EXPENSE RISK FEE OR ADMINISTRATION AND DISTRIBUTION FEE CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender charges, mortality and expense risk fee or administration and
distribution fee for Portfolio Director 2 may be reduced or waived. We may
reduce or waive these fees and charges if we determine that your retirement
program will allow us to reduce or eliminate administrative or sales expenses
that we usually incur for retirement programs. There are a number of factors we
will review in determining whether your retirement program will allow us to
reduce or eliminate these administrative or sales expenses:
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
  We review the following additional factors to determine whether we can reduce
  or waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review to following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
  We review the following additional factors to determine whether we can reduce
  or waive the mortality and expense fee or administration and distribution fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
  We will only do this if permitted by this Contract and by VALIC guidelines in
  effect at the time. In no event will the reduction or waiver of fees and
  charges be permitted where the reduction or waiver will unfairly discriminate
  against any person.
 
  SEPARATE ACCOUNT EXPENSE
  REIMBURSEMENT
 
  Some of the Mutual Funds or their affiliates may have an agreement with the
  Company to pay the Company for certain administrative and shareholder services
  it provides to the underlying Fund. The Company will reduce its charges to the
  Division investing in that Fund by the full amount of any of these payments it
  receives. In addition, the Company currently reimburses certain Divisions a
  portion of the Company's administration and distribution fee. Such
  reimbursement arrangements are voluntary. See the Fee Table in this prospectus
  for an identification of those Funds for which a reimbursement applies.

PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
(1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
   
With a Variable Payout, you may select from your existing Variable Account
Options. Your payments will vary accordingly. This is due to the varying
investment results that will be experienced by each of the Variable Account
Options you selected. The Payout Unit Value is calculated just like the Purchase
Unit Value for each Variable Account Option except that the Payout Unit Value
includes a factor for the Assumed Investment Rate you select. For additional
information on how Payout Payments and Payout Unit Values are calculated, see
the Statement of Additional Information.
    
 
   
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the Variable Account Option is lower than your
Assumed Investment Rate, your next payment will be less than your first payment.
    
 
COMBINATION FIXED AND VARIABLE
PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
   
Up to seven Variable Account Options may be chosen, or up to six Variable
Account Options if the Fixed Payout is chosen.
    
 
PAYOUT DATE
The Payout Date is the date elected by you on which your payout (annuity)
payments will start. The date elected must be the first of any month provided 30
days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              29
<PAGE>   371
 
- --------------------------------------------------------------------------------
 
    - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
      lifetime. Upon your death, your beneficiary will receive a lump sum
      payment equal to the remaining Annuity Value.
 
    - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
      lifetime of you and your beneficiary. Upon the death of one, payments
      continue during the lifetime of the survivor. This option is designed
      primarily for couples who require maximum possible variable payouts during
      their joint lives and are not concerned with providing for beneficiaries
      at death of the last survivor. For example, it would be possible under
      this option for the Joint Annuitants to receive only one payment if both
      Annuitants died prior to the date of the second payment, or for the Joint
      Annuitants to receive only one payment and the surviving Annuitant to
      receive only one payment if one Annuitant died prior to the date of the
      second payment and the surviving Annuitant dies prior to the date of the
      third payment.
 
    - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
      number of years between five and thirty. Upon your death, payments will
      continue to your beneficiary until the designated period is completed.
 
ENHANCEMENTS TO PAYOUT OPTIONS
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. The Joint and Survivor
Life Option may be available with a one to twenty year guaranteed period option.
Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
   
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
    
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option, and
 
   
  - The payments will be guaranteed for a 10 year period,
    
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
   
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis, and
    
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
   
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or plan.

Additional Information".

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.
 
AMOUNT THAT MAY BE SURRENDERED
The amount that may be surrendered at any time can be determined as follows:
 
<TABLE>
<S>                    <C>               <C>
                                               Your
                                              Account
       Allowed                               Value(1)
      Surrender           = (EQUALS)         - (MINUS)
        Value                             Any Applicable
                                             Surrender
                                              Charge
</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
   
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See your current Fund(s)' prospectuses
for a discussion of the reasons why the redemption of shares may be suspended or
postponed.
    
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
 
Under the FLORIDA STATE OPTIONAL RETIREMENT PROGRAM, no surrender or partial
surrender of Purchase Payments made by the employer will be allowed except for
termination of employment, retirement or death. Benefit payments based on
payments from the employer may not be paid in a lump sum or for a period
certain, but must be paid under a life contingency option, except for:
 
  - death benefits; and
 
  - certain small amounts approved by the State of Florida.
 
   
Under the LOUISIANA OPTIONAL RETIREMENT PLAN retirement benefits must be paid in
the form of a lifetime income, and except for death benefits, single sum
surrenders and partial surrenders out of the plan are not permitted.
    
 
   
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
    
 
PARTIAL SURRENDERS
   
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Options first unless otherwise specified by you.
    
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director 2. There will be no surrender charge for withdrawals using this method,
which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
 
                                                                              31
<PAGE>   373
- --------------------------------------------------------------------------------
 
revoked, a systematic withdrawal may not be elected again. No more than one
systematic withdrawal election may be in effect at any one time. We reserve the
right to discontinue any or all systematic withdrawals or to change its terms,
at any time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW. There will be no surrender charge on
a minimum distribution required by federal tax law (known as No Charge Minimum
Distribution), if the withdrawal:
 
  - Is made payable to you; and
 
  - Does not exceed the amount required under federal tax law as determined by
    the values in your Portfolio Director 2 Contract and VALIC.
 
This contract feature will not be available in any year that an amount has been
withdrawn under the no charge systematic withdrawal method. See "Federal Tax
Matters" in this prospectus and in the Statement of Additional Information for
more information about required distributions imposed by tax law.
 
For an explanation of possible adverse tax consequences of a surrender, see
"Federal Tax Matters" in this prospectus and in the Statement of Additional
Information.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
   
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director 2. These other contracts are listed below. We
will allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director 2. This exchange privilege will be available
only to other contracts purchased through your employer-sponsored retirement
plan and for which we have not yet started making payments under a Payout
Option. If you elect to exercise one of these exchange offers, you should
contact any of our Regional Offices at the addresses shown in the back of this
prospectus. An exchange may require the issuance of a Contract or may be subject
to any other requirements that the Company may impose.
    
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
   
  - Exchanges from Portfolio Director 2 to contract forms other than Portfolio
    Director Plus are not permitted.
    
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director 2. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director 2. For example, you
will be subject to the rules concerning transfers among investment options as
stated in the Transfers Between Investment Options section in this prospectus.
We may, at our option, waive any transfer restrictions for a stated period of
time. If we waive these transfer restrictions, you will be allowed to exchange
to any investment option available in Portfolio Director 2.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director 2.
 
SURRENDER CHARGES
 
We will generally not impose nor waive existing surrender charges as a result of
your electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director 2 will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director 2, the
contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director 2 will be the same date as the other contract, but no
earlier than January 1, 1982. (The effect of this is to potentially shorten the
charge period for Purchase Payments subsequently made to Portfolio Director 2.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director 2 for purposes of calculating the surrender charge. The effective dates
of these Purchase Payments will also be retained for surrender charge purposes.
 
The Portfolio Director 2 surrender charge is calculated assuming the most recent
Purchase Payments are removed first. This policy may cause exchanged funds to be
accessible only after charges are imposed.

AGENTS' AND MANAGERS' RETIREMENT PLAN
EXCHANGE OFFER
 
General. All eligible agents and managers of the Company are allowed to
participate in the Company's Agents' and Managers' Retirement Plan ("Plan"). We
grant to participants in the Plan the right to effect a voluntary exchange of
their units of interest under the SA-1 Contracts, Independence Plus Contracts
and Portfolio Director for the equivalent units of interest in Portfolio
Director 2.
 
Agents and managers of VALIC who enter into the voluntary exchange will not
incur under Portfolio Director 2 any surrender charges or account maintenance
fees. Other individuals who may exchange to Portfolio Director 2 from SA-1,
Independence Plus or Portfolio Director Contracts may have surrender charges and
account maintenance fees imposed under Portfolio Director 2. All other
provisions with regard to exchange offers referenced in the section entitled
"Exchange Offers" will apply to the Agents' and Managers' Retirement Plan
Exchange Offer.
 
Pursuant to this voluntary exchange offer, participants in the Plan will have
three options to choose from. As to the funding vehicle for
 
 34
<PAGE>   376
 
- --------------------------------------------------------------------------------
 
their purchase payment plan, the participant may choose to:
 
  - Remain in the SA-1 Contract, Independence Plus Contract or Portfolio
    Director.
 
  - Leave current assets in the SA-1 Contract, Independence Plus or Portfolio
    Director and direct future Purchase Payments to Portfolio Director 2; or
 
  - Transfer all current assets and future Purchase Payments to Portfolio
    Director 2.
 
If the participant chooses to remain in either the SA-1 Contract, Independence
Plus Contract or Portfolio Director, future Purchase Payments and current assets
will be controlled by the provisions of the SA-1 Contract, Independence Plus
Contract or Portfolio Director, respectively. If the participant chooses to
leave current assets in the SA-1 Contract, the Independence Plus Contract or
Portfolio Director and direct future Purchase Payments to Portfolio Director 2,
the current assets will be controlled by the provisions of the SA-1 Contract,
the Independence Plus Contract or Portfolio Director, respectively. The future
Purchase Payments will be controlled by the terms of Portfolio Director 2
subject to the exception that surrender charges and account maintenance fees
will not be imposed under Portfolio Director 2. If the participant chooses to
transfer all current assets and future Purchase Payments to Portfolio Director
2, such current assets and future Purchase Payments will be controlled by the
provisions of Portfolio Director 2 subject to the exception that surrender
charges and account maintenance fees will not be imposed under Portfolio
Director 2.
 
   
Once a participant transfers assets and future Purchase Payments to Portfolio
Director 2 the participant will not be permitted to exchange back to the SA-1
Contract or Independence Plus Contract. See "Exchange Offer for Portfolio
Director and Portfolio Director 2" in this prospectus. If a participant chooses
to transfer future Purchase Payments but not current assets to Portfolio
Director 2, the participant will be allowed at a later date to transfer the
current assets to Portfolio Director 2. For a complete analysis of the
differences between the SA-1 contract, the Independence Plus Contract or
Portfolio Director and Portfolio Director 2, you should refer to the Statement
of Additional Information and the form of the contract or certificate for its
terms and conditions.

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director 2 will pay death benefits during either the Purchase Period
or the Payout Period. How these death benefits will be paid are discussed below.
The death benefit provisions in Portfolio Director 2 may vary from state to
state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
- - In a lump sum; or
 
- - In the form of an annuity under any of the Payout Options stated in the Payout
  Period section of this prospectus subject to the restrictions of that Payout
  Option.
 
   
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
    
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
- - In full within 5 years after the Annuitant's death; or
 
- - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
   
  - An annuity for a designated period not exceeding the Beneficiary's life
    expectancy
    
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director 2.
 
SPECIAL INFORMATION FOR INDIVIDUAL
NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the Annuitant's death. However, the Contract
will be transferred to the Contingent Owner,
if any, or to the Contract Owner's estate. Such transfers will be considered a
taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:

Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
  Value of Fixed Account Option on date
  proof of death Is received by VALIC

  OR

  100% of Purchase Payments placed
  in Fixed Account Option

- - (minus)

  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
  Value of Variable Account Option on date
  proof of death is received by VALIC

  OR

  100% of Purchase Payments placed in
  Variable Account Options

- - (minus)

  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option

+ (plus)

  Interest at an annual rate of 3%
 
Step 3: Add step 1 + 2 = Death Benefit
 
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
BENEFICIARY -- the person
designated to receive Payout
Payments upon the death of
an Annuitant.
 
ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid.
 
   
CONTRACT OWNER -- either
your employer or organization
in the case of a group
contract or the Annuitant in
the case of an individual
contract. If the contract is an
individual non-qualified type,
this is generally the Annuitant
but is not required to
be. Also, a Contingent
Contract Owner may be designated.
    
 
FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options. Currently,
the Fixed Account Options in
Portfolio Director 2 are Fixed
Account Plus and Short-Term
Fixed Account. Each option
of this type is guaranteed to
earn at least a minimum rate
of interest.
 
   
VARIABLE ACCOUNT
OPTIONS -- investment
options that correspond to
VALIC Separate Account A
Divisions offered by Portfolio
Director 2. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.

  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director 2 are described in the "Payout Period" section
of this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed
       period option chosen by the deceased Participant; or
 
     - Receive the present value of any remaining payments applied under the
       Payment for a Designated Period Option for a period equal to or shorter
       than the period remaining. Spouse beneficiaries may be entitled to more
       favorable treatment under federal tax law.

HOW TO REVIEW INVESTMENT PERFORMANCE
OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
   
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts or to the general public
before Portfolio Director 2 was first available to you. We may therefore,
advertise investment performance since the inception of the underlying Funds. In
each case, we will use the charges and fees imposed by Portfolio Director 2 in
calculating the Division's investment performance for earlier time frames.
    
 
TYPES OF INVESTMENT PERFORMANCE
INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE
INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Standard Average Annual Total Return shows the average percentage change in the
value of an investment in the Division from the beginning to the end of a given
historical period. The results shown are after all charges and fees have been
applied against the Division. This will include account maintenance fees and
surrender charges that would have been deducted if you surrendered Portfolio
Director 2 at the end of each period shown. Premium taxes are not deducted. This
information is calculated for each Division based on how an initial assumed
payment of $1,000 performed at the end of 1, 3, 5 and 10 year periods. If
Standard Average Annual Return for a Division is not available for a stated
period, we may show the Standard Average Annual Return since Division inception.
    
 
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
 
NONSTANDARD AVERAGE ANNUAL TOTAL
RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance information of an underlying Fund
reduced by Account fees for a period prior to the inception of the corresponding
Division is nonstandard performance information regardless of whether all
account fees and charges are deducted.
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director 2 will stay
in the Division beyond the time that a surrender charge would apply. It may be
calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    

DIVISIONS -- subaccounts of
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director 2. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director 2.
 
For more information on how
TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.
 
 38
<PAGE>   380
 
- --------------------------------------------------------------------------------
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the Division's Annual
Change in Purchase Unit Value.
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT
INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director 2 charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC MONEY MARKET DIVISION
 
We may advertise the AGSPC Money Market Division's Current Yield and Effective
Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market Division over a given 7-day period. The Current Yield does not take
into account surrender charges, account maintenance fees or premium taxes. The
income produced over a 7 day period is then "annualized." This means we are
assuming the amount of income produced during the 7-day period will continue to
be produced each week for an entire year. The annualized amount is shown as a
percentage of the investment. The annualized 7-day Current Yield for the last 7
days ended December 31, 1998 was 3.84%.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause
the Effective Yield to be higher than the Current Yield. The annualized 7-day
Effective Yield for the last 7 days ended December 31, 1998 was 3.91%.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET DIVISION
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market Division. The yield for each of these Divisions will be
determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION:
 
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
   
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate Account A
Division is printed in the six tables below.
    
 
The information presented does not reflect the advantage under Portfolio
Director 2 of deferring federal income tax on increases in Account Value due to
earnings attributable to Purchase Payments (see "Federal Tax Matters" in the
prospectus and in the Statement of Additional Information.) The information
presented also does not reflect the advantage under Qualified Contracts of
deferring federal income tax on Purchase Payments.
 
The performance information presented in the following tables reflects the
performance of the underlying Fund after deduction of a mortality and expense
risk fee and administration and distribution fee at an aggregate annualized rate
of 0.80% to 1.05% during the Purchase Period on the daily net asset value of
VALIC Separate Account A. The exact rate depends upon the Variable Account
Option selected.
 
The performance results shown in the following tables are not an estimate or
guarantee of future investment performance, and do not represent the actual
experience of amounts invested by a particular Participant.

CHANGE OF BENEFICIARY
 
The Beneficiary (if not irrevocable) may usually be changed at any time.
 
Under some retirement programs, the right to name or change a Beneficiary is
subject to approval by the spouse. Also, the right to name a Beneficiary other
than the spouse may be subject to certain tax laws and regulations.
 
If the Annuitant dies, and there is no Beneficiary, any death benefit will be

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director 2
was issued in connection with a nonqualified and unfunded deferred compensation
plan.
 
DETERMINATION OF FUND SHARES
ATTRIBUTABLE TO YOUR ACCOUNT
 
DURING PURCHASE PERIOD
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
DURING PAYOUT PERIOD OR AFTER A DEATH
BENEFIT HAS BEEN PAID
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director 2
may have a number of shareholders including VALIC Separate Account A, VALIC
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies and public shareholders.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
   
VALIC Separate Account A will vote the shares of the Funds it holds based on,
and in the same proportion as, the voting instructions received from
participants in VALIC Separate Account A.
    
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.

FEDERAL TAX MATTERS
- --------------------------------------------------------------------------------
 
Portfolio Director 2 provides tax-deferred accumulation over time, but is
subject to federal income and excise taxes, mentioned briefly below. You should
refer to the Statement of Additional Information for further details. Section
references are to the Internal Revenue Code ("Code"). We do not attempt to
describe any potential estate or gift tax, or any applicable state, local or
foreign tax law other than possible premium taxes mentioned under "Premium Tax
Charge." Remember that future legislation could modify the rules discussed
below, and always consult your personal tax adviser regarding how the current
rules apply to your specific situation.
 
TYPE OF PLANS
 
   
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program or 408(b) IRA, as a Section 408(b)
Individual Retirement Annuity ("IRA"), or is instead a nonqualified Contract.
Portfolio Director 2 is used under the following types of retirement
arrangements:
    
 
  - Section 403(b) annuities for employees
     of public schools and
     Section 501(c)(3) tax-exempt
     organizations;
 
  - Section 401(a) and 403(a) qualified plans of for-profit employers and other
    employers (including self-employed individuals);
 
   
  - Section 408(b) IRAs;
    
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
   
  - Section 408(k) SEPs.
    
 
  - Section 408(p) SIMPLE Retirement
     Accounts
 
   
The foregoing Contracts are "Qualified Contracts." Certain series of Portfolio
Director 2 may also be available through a nondeductible Section 408A "Roth"
individual retirement annuity ("Roth IRA").
    
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
   
In addition, Portfolio Director 2 is also available through "Non-Qualified
Contracts" to the extent acquired by "Non-Natural Persons." Such Non-Qualified
Contracts generally include unfunded, nonqualified deferred compensation plans
of corporate employers as well as individual annuity contracts issued to
individuals outside of the context of any formal employer or employee retirement
plan or arrangement. Non-Qualified Contracts generally may invest only in mutual
funds which are not available to the general public outside of annuity contracts
or life insurance contracts.
    
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director 2 can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Qualified Contracts receive deferral of tax on
the inside build-up of earnings on invested Purchase Payments, until a
distribution occurs. See the Statement of Additional Information for special
rules, including those applicable to taxable, non-natural owners of
Non-Qualified Contracts.
 
   
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
    
 
Distributions are taxed differently depending on the program through which
Portfolio Director 2 is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
   
Amounts subject to income tax may also incur excise or penalty taxes, under the
circumstances described in the Statement of Additional Information. Generally,
they would also be subject to some form of federal income tax withholding unless
rolled into another tax-deferred vehicle. Required withholding will vary
according to type of program, type of payment and your tax status. In addition,
amounts received
    
 
                                                                              45
<PAGE>   387
- --------------------------------------------------------------------------------
 
under all Contracts may be subject to state income tax withholding requirements.
 
   
It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if purchase payments under the contract are invested in
publicly available mutual funds. In a ruling published in 1981, the Internal
Revenue Service ("IRS") had taken the position that, where purchase payments
under a variable annuity contract are invested in publicly available mutual
funds, the contract owner should be treated as the owner of the mutual fund
shares, and deferred tax treatment under the contract should not be available.
In the opinion of VALIC and its tax counsel, the 1981 ruling has been superseded
by subsequent legislation (Code Section 817(h)) which specifically exempts these
Qualified Contracts, and the IRS has no viable legal basis or reason to apply
the theory of the 1981 ruling to these Qualified Contracts under current law.
Although VALIC can provide no assurance that the IRS will not challenge the
deferred tax treatment of these Qualified Contracts under the theory of the 1981
ruling, VALIC and its tax counsel believe that Contract owners would prevail if
such a challenge were made.
    
 
   
It is also the opinion of VALIC and its tax counsel that for each other type of
Qualified Contract an independent exemption provides tax deferral regardless of
how ownership of the Mutual Fund shares might be imputed for federal income tax
purposes.
    
 
   
Investment earnings on contributions to Non-Qualified Contracts which are not
owned by natural persons will be taxed currently to the owner and such contracts
will not be treated as annuities for federal income tax purposes.
    
 
EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director 2 Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
 
   
                        THE POWER OF TAX-DEFERRED GROWTH
    
                                  [BAR GRAPH]
 
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. The deduction of
fees and charges for both tax-deferred plans is reflected in the chart. Variable
options incur mortality and expense risk fee and administration and distribution
fee charges (0.80% - 1.05% during the purchase period and 1%-1.25% during the
payout period) and may also incur account maintenance fees ($3.75 per quarter)
and surrender charges (5% of the lesser of all contributions received during the
last 60 months or the amount withdrawn). The dotted lines represent the amounts
remaining after withdrawal and payment of taxes and any surrender charge. An
additional 10% tax penalty may apply to withdrawals before age 59 1/2. This
information is for illustrative purposes only and is not a guarantee of future
return.
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.
 
To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE
REDUCED BY THE IMPACT OF INCOME TAXES UPON WITHDRAWAL. The yield will vary
 
 46
<PAGE>   388
- --------------------------------------------------------------------------------
 
depending upon the timing of withdrawals. The previous chart represents (without
factoring in fees and charges) after-tax amounts that would be received.
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

</TABLE>
 
This chart assumes a 28% federal income tax rate. The $700 which is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800, while the full $2,500 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a tax-
qualified retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-qualified retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
YEAR 2000 RISKS
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
  - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
    Problem. This plan includes the five steps that we believe are essential to
    Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or
    replace systems that are not Year 2000 ready; (4) test systems to prove that
    they will work correctly into the year 2000; and (5) return the systems to
    operations. As of December 31, 1998, we have substantially completed all
    steps with respect to our critical systems.
    
 
   
  - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that
    must also be Year 2000 ready. Third parties are companies that provide
    certain services to VALIC. Third parties are different from internal systems
    in that VALIC has less, or no, control over their Year 2000 readiness. VALIC
    has developed a plan to review and try to lessen the Year 2000 risks of
    third parties. As of December 31, 1998, VALIC has substantially completed
    its review of third party Year 2000 risks. VALIC intends to test third party
    Year 2000 readiness throughout 1999.
    
 
   
  - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
    associated with the Year 2000 Problem. The contingency plans for third party
    relationships include the following activities: (1) evaluate the
    consequences of any failures associated with the Year 2000 Problem; (2)
    determine the chance of a Year 2000-related failure for systems that have a
    high chance of failing; (3) develop an action plan to complete contingency
    plans for those systems that rank high in both impact of failure and chance
    of failure; and (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.

Portfolio Director 2 that consist of group and individual variable annuity
contracts (the "Contracts") to Participants in certain employer sponsored
retirement plans. Portfolio Director 2 Series 2.1.40 to 2.12.40 consists of
group variable annuity contracts that are offered by Valic to Participants in
certain employer sponsored retirement plans as well as for certain after-tax

up to 2 Fixed Account Options and/or an array of up to 18 Variable Account
Options. If your contract is part of your employer's retirement program, that
program will describe which Variable Account Options are available to you. If
your contract is a tax-deferred nonqualified annuity that is not part of your
employer's retirement plan, those Variable Account Options that are invested in
Mutual Funds available to the public outside of annuity contracts, life
insurance contracts, or certain employer-sponsored retirement plans will not be
available within your contract. Each of these investment options is explained

    during the Payout Period is computed at an annualized rate of 1.00% to
    1.25%, depending upon the Variable Account Option selected.
    
 
   
(4) For these Funds the Total Separate Account Fee equals the VALIC Separate
    Account A mortality and expense risk fee plus the administration and
    distribution fee reduced by the Separate Account Expense Reimbursement.
    Pursuant to the Separate Account Expense Reimbursement the Company's charges
    to these Divisions are reduced by an amount equal to payments from the
    underlying Fund and/or its affiliate for administrative and shareholder
    services provided by the Company. See "Fees and Charges -- Separate Account
    Expense Reimbursement" in this prospectus for more information.
    
 
   
    The following Funds and/or their affiliates pay administrative, shareholder
    service or distribution fees to the Company: American Century (0.21%),
    Founders (0.25%), Neuberger Berman (0.25%), Putnam (0.25%), Scudder (0.25%)
    and Templeton (0.25%). With respect to American Century Ultra Fund, the Fund
    pays fees to the Company of 0.20% on assets in excess of $0 but less than
    $75 million, and 0.25% on assets equal to or in excess of $75 million.
    
 
   
(5) For these Funds the Total Separate Account Fee equals the VALIC Separate
    Account mortality and expense risk fee plus the administration and
    distribution fee reduced by the Separate Account Expense Reimbursement. The
    Separate Account Expense Reimbursement reflects a voluntary expense
    reimbursement made by the Company, directly to the Division, which may be
    terminated by the Company at any time without notice.
    
 
   
(6) OTHER EXPENSES includes custody, accounting, reports to shareholders, audit,
    legal and other miscellaneous expenses. See each Fund's prospectus for a
    detailed explanation of these fees.
    
 
   
(7) Neuberger Berman Guardian Trust ("Trust") has identical investment
    objectives and policies and invests in the same portfolio as Neuberger
    Berman Guardian Fund ("Fund"). Both the Fund and the Trust are managed by
    Neuberger Berman Management Inc. ("NB"). NB voluntarily bears certain
    expenses of the Trust so that the Trust's expense ratio per annum will not
    exceed the expense ratio per annum of the Fund by more than 0.10% of the
    Trust's average daily net assets. This arrangement can be terminated on
    sixty days' notice. For this Fund, MANAGEMENT FEES include administration
    expenses. For the Trust's 1998 fiscal year, NB did not bear any expenses.

(1)  Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of
     Bankers Trust Corporation. On November 30, 1998, Bankers Trust Corporation
     entered into an Agreement and Plan of Merger with Deutsche Bank AG under
     which Bankers Trust Corporation and all of its subsidiaries would merge
     with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a major
     global banking institution that is engaged in a wide range of financial
     services, including retail and commercial banking, investment banking and
     insurance. The merger is contingent upon various regulatory approvals. On
     April 20, 1999, the Fund's Board of Directors approved a new investment
     sub-advisory agreement with Bankers Trust Company, subject to shareholder
     approval. If the merger is approved and completed, Deutsche Bank AG, as the
     Sub-Adviser's new parent company, will control the operations of the
     Sub-Adviser, Bankers Trust believes that, under this new arrangement, the
     services provided to the Fund will be maintained at their current level.

SUMMARY -- (CONTINUED)
    
- --------------------------------------------------------------------------------
 
   
A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
    
 
INTEREST GUARANTEED DEATH
BENEFIT
Portfolio Director 2 offers a death benefit with an interest guarantee when
death occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director 2 offers a tax-free loan provision for tax-qualified
contracts that gives you access to your money in either of the Fixed Account
Options, subject to a minimum loan amount of $1,000. The availability of loans
is subject to government regulations, as well as your employer's plan
provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e. loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
There is no charge to transfer the money in your account among Portfolio
Director 2's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you have withdrawn. The second amount is
5% of the contributions you made to your account during the last 60 months.
 
Withdrawals are always subject to your plan generally include a tax penalty on
withdrawals made prior to age 59 1/2.
 
PREMIUM TAX CHARGE
   
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
    
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
aggregate annualized rate of 0.60% to 0.85% during the purchase period and 1.00%
to 1.25% during the payout period on the average daily net asset value of VALIC
Separate Account A. Reductions in the mortality and expense risk fee and
administration and distribution fee may be available for plan types meeting
certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.
 
SEPARATE ACCOUNT
EXPENSE REIMBURSEMENT
   
The Company will reimburse to certain Divisions any fees it receives from the
Mutual Fund or its affiliate or distributor for providing the Mutual Fund
administrative and shareholder services. In addition, the Company currently
reimburses certain Divisions a portion of the Company's administration and
distribution fee for providing Variable Account Options. Such reimbursement
arrangements are voluntary. For more information as to which Variable Account
Options have a Separate Account Expense Reimbursement see the Fee Table.
    
 
PAYOUT OPTIONS
When you withdraw your money, you can select from several payout options: a
lifetime annuity (which guarantees payment for as long as you live), periodic
withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.
 
FEDERAL TAX INFORMATION
Although deferred annuity contracts such as Portfolio Director 2 can be
purchased with after-tax dollars, they are primarily used in connection with
retirement programs which receive favorable tax treatment under federal law.
 
PURCHASE REQUIREMENTS
Purchase Payments may be made at any time and in any amount, subject to plan
limitations.
 
To learn more about the
INTEREST GUARANTEED DEATH
BENEFIT, refer to the section
in the prospectus entitled
"Death Benefits."
 
More information on FEES
may be found in the
prospectus under the
headings "FEES AND
CHARGES" AND "FEE TABLE."
 
For a more detailed
discussion of these income
tax provisions, see the
"FEDERAL TAX MATTERS"
section of the prospectus and
of the Statement of Additional
Information.
 
For more information on
PURCHASE PAYMENTS, refer
to the "Purchase Period"
section of the prospectus.

Financial statements of VALIC Separate Account A are included in the Statement
of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
Contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

ABOUT VALIC SEPARATE ACCOUNT A
When you direct money to Portfolio Director 2's Variable Account Options, you
will be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director 2. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account.
 
VALIC Separate Account A is made up of what we call "Divisions." Eighteen
Divisions are
available and represent the Variable Account Options in Portfolio Director 2.
Each of these Divisions invests in a different Mutual Fund made available
through Portfolio Director 2. For example, Division Ten represents and invests
in the Stock Index Fund. The earnings (or losses) of each Division are credited
to (or charged against) the assets of that Division, and do not affect the
performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25, 1979 under Texas insurance law
to allow you to be able to invest in a number of Variable Account Options
available in Portfolio Director 2. VALIC Separate Account A is registered with
the Securities and Exchange Commission (SEC) as a unit investment trust under
the Investment Company Act of 1940 ("Act"). Units of interest in VALIC Separate
Account A are registered as securities under the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director 2, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director 2, the
Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director 2 be held exclusively for the benefit of the
contract owner, participants, annuitants, and beneficiaries of Portfolio
Director 2. When we discuss performance information in this prospectus, we mean
the performance of a VALIC Separate Account A Division.
 
UNITS OF INTERESTS
Your investment in a Division of VALIC Separate Account A is represented by
units of interest issued by VALIC Separate Account A. On a daily basis, the
units of interest issued by VALIC Separate Account A are revalued to reflect
that day's performance of the underlying mutual fund minus any applicable fees
and charges to VALIC Separate Account A.
 
   
DISTRIBUTION OF THE CONTRACTS
    
 
   
A.G. Distributors, Inc. ("A.G. Distributors"), an affiliate of VALIC, acts as
VALIC's Separate Account A distributor.
    
 
   
VALIC will pay the licensed agents who sell the Contracts a commission.
Currently, the commission paid by VALIC will range up to 6.0% of each Purchase
Payment. In addition, VALIC will pay managers who supervise the agents
overriding commissions ranging up to 1% of each Purchase Payment. These various
commissions are paid by VALIC and do not result in any charge to Contract Owners
or to the Separate Account.

SUMMARY OF FUNDS
 
   
A brief summary of the investment objectives of each Mutual Fund is shown below.
In addition to the investment objectives, the Account Value of an assumed
$10,000 investment in each of the Divisions is shown in both table and graph
form as well as the Standard Average Annual Total Return for a 1, 3, 5 and 10
year period, if available. If Standard Average Annual Return for a Division is
not available for a stated period, we may show the Standard Average Annual
Return since Division inception. The performance information in the tables and
graphs will reflect a deduction for separate account fees (mortality and expense
risk fees plus administration and distribution fees minus any applicable
reimbursements) and underlying fund charges. They will not reflect any deduction
for account maintenance fees, surrender charges and premium taxes. These charges
would further reduce your return. The Account Values shown reflect in the graphs
Separate Account performance based on the performance of the underlying Fund for
the last 10 fiscal years or, since inception of the underlying Fund if for less
than 10 years. The returns shown in the tables reflect for the AGSPC Funds
actual historical performance of the related Separate Account Divisions. The
returns shown in the tables for the other Funds (Divisions 21-32) reflect actual
historical performance of the related Separate Account Divisions since inception
of each Division (July 1, 1996) and hypothetical performance for periods prior
to July 1, 1996. Hypothetical performance is based on the actual performance of
the underlying Fund reduced by Separate Account fees that would have been
incurred during the hypothetical period. Investment return and principal value
will fluctuate with market conditions, and for foreign investments, currencies
and the economic and political climates of the countries where investments are
made. Past performance cannot predict or guarantee future results.
    
 
   
The Standard Average Annual Total Return figures show the average percentage
change in the value of an investment in a Division from the beginning to the end
of the historical periods shown below. The results shown are after all charges
and fees have been applied against the Division. This will include account
maintenance fees and surrender charges that would have been deducted if you
surrendered Portfolio Director 2 at the end of the specified period. Premium
taxes are not deducted. This information is calculated for each Division based
on how an initial investment of $1,000 performed at the end of the specified
periods shown.
    
 
For more information about how these returns were calculated including a
statement of the charges reflected and tables showing historical performance
information see "How to Review Investment Performance of Separate Account
Divisions" in this prospectus.

INVESTMENT OBJECTIVE
 
Seeks conservation of principal, a reasonable income return, and profits without
undue risk.
 
This Fund seeks relative capital stability, a reasonable level of income, and
the potential for capital appreciation. By balancing its investments among
common stocks and bonds, the Fund is expected to provide lower investment risk
and share price volatility (and a lower return in the long run) than a mutual
fund which invests exclusively in common stocks.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director 2 account is surrendered before the Payout Period. The
amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director 2 was purchased.
 
PURCHASE PAYMENTS
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account.
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>
<CAPTION>
                         Initial    Subsequent
     Contract Type       Payment     Payment

Single Payment           $1,000         -0-
</TABLE>
 
   
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
    
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
   
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments within 5 business days if the requested information is not
  provided unless you otherwise so specify.
    
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under these circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment
 
  in an "Employer-Directed" account invested in our Money Market Division
  Option. You may not transfer these amounts until VALIC has received a
  completed application or enrollment form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  Money Market Division. We will send you follow-up letters requesting the
  information necessary to complete the application, including your allocation
  instructions. Unless a completed application or enrollment form is received by
  us within 105 days of establishment of your starter account, the account
  balance, including earnings, will be returned to your employer. We are not
  responsible for any adverse tax consequences to you that may result from the
  return of your employer's contributions.
 
PURCHASE UNITS
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
The Purchase Unit value for a Division is calculated as shown below:
Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income and capital gains and losses (whether
  realized or unrealized) on that day from the assets attributable to the
  Division.
/ (DIVIDED BY)
  The value of the Division for the immediately preceding day on
  which the values are calculated.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director 2.
 
   
PURCHASE UNIT -- a
    
   
measuring unit used to
    
   
calculate your Account Value
    
   
during the Purchase Period.
    
   
The value of a Purchase Unit
    
   
will vary with the investment
    
   
experience of the Separate
    
   
Account Division you have
    
   
selected.
    
 
For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.
 
                                                                              21
<PAGE>   422
 
- --------------------------------------------------------------------------------
 
   
We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the Exchange is open.
    
Step 2: Calculate net investment rate for any day as follows:
 
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
 
  Purchase Unit Value for that day.
= (EQUALS)
  Purchase Unit Value for immediate preceding day.
X (MULTIPLIED BY)
  Net Investment Rate (as calculated in Step 2) plus 1.00.
 
CHOOSING INVESTMENT OPTIONS
   
There are 20 investment options offered in Portfolio Director 2. This includes 2
Fixed Account Options and 18 Variable Account Options. Unless provided
otherwise, you
may select and combine up to 7 of the 20 options. The Funds that underlie the
Variable Account Options are registered as investment companies under and are
subject to regulation of the Act. The Fixed Account Options are not subject to
regulation under the Act and are not required to be registered under the
Securities Act of 1933. As a result, the SEC has not reviewed data in this
prospectus that relates to the Fixed Account Options. However, federal
securities law does require such data to be accurate and complete.
    
 
FIXED ACCOUNT OPTIONS
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in Summary appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed Account Options
= (EQUALS)
  All Purchase Payments made to the Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable Account Options to the Fixed Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn from Fixed Account Options (including
  applicable fees and charges)
 
VARIABLE ACCOUNT OPTIONS
   
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. A complete discussion of each of the Variable Account Options may be
found in the "Variable Account Options" section in this prospectus. Based upon a
Variable Account Option's Purchase Unit Value your account will be credited with
the applicable number of Purchase Units. The Purchase Unit Value of each
Variable Account Option will change daily depending upon the investment
performance of the underlying fund (which may be positive or negative) and the
deduction of VALIC Separate Account A charges. See the "Fees and Charges"
section in this prospectus. Because Purchase Unit Values change daily, the
number of Purchase Units your account will be credited with for subsequent
Purchase Payments will vary. Each Variable Account Option bears its own
investment risk. Therefore, the value of your account may be worth more or less
at retirement or withdrawal.
    
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director 2 account has been surrendered. The
value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
   
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any
such account closure will be subject to applicable distribution restrictions
under the Contract and/or under your employer's plan.
    
 
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.

TRANSFERS BETWEEN INVESTMENT OPTIONS
- --------------------------------------------------------------------------------
 
You may transfer all or part of your Account Value between the various Fixed
Account and Variable Account Options in Portfolio Director 2 without a charge.
Transfer instructions may be made either in writing or by telephone as discussed
below. Transfers may be made during the Purchase Period or during the Payout
Period. We reserve the right to limit transfers as discussed below. Your
employer's plan may also limit your rights to transfer.
 
DURING THE PURCHASE PERIOD
During the Purchase Period, transfers may be made between Portfolio Director 2's
Fixed Account Options and Variable Account Options.
 
We currently permit transfers between Variable Account Options or from Variable
Account Options to Fixed Account Options, at any time. We may, however, limit
the number of transfers you can make.
 
Transfers are also permitted from the Fixed Account Options subject to the
following limitations:

COMMUNICATING TRANSFER OR
REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director, should be
sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
   
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
    
 
- - The next date values are calculated.

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director 2, you may be subject to six basic types of
fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director 2 is issued to certain types of plans which are expected to result in
lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
   
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
    
 
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is
 
actually withdrawn. We consider all Purchase Payments to be withdrawn before
earnings are withdrawn.
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
 
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

- --------------------------------------------------------------------------------
 
- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy of a Social Security Administration determination or a doctor's
  verification; or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director 2 is issued
to certain types of plans which are expected to result in lower costs to VALIC.
To learn more about how we determine if a surrender charge may be reduced or
waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
   
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
    
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an aggregate annualized rate of 0.60% to 0.85% during the Purchase Period and
1.00% to 1.25% during the Payout Period on the average daily net asset value of
VALIC Separate Account A. The exact rate depends on the Variable Account Option
selected. This charge is guaranteed and cannot be increased by the Company. The
mortality and expense risk fee is to compensate the Company for assuming
mortality and expense risks under Portfolio Director. The mortality risk that
the Company assumes is the obligation to provide payments during the Payout
Period for your life no matter how long that might be. In addition, the Company
assumes the obligation to pay during the Purchase Period an interest guaranteed
death benefit. For more information about the interest guaranteed death benefit
see the "Death Benefit" section of this prospectus. The expense risk is our
obligation to cover the cost of issuing and administering Portfolio Director 2,
no matter how large the cost may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing, (including but not limited to
enrollment, participant communication and education).
 
For more information about the mortality and expense risk fee and on the
administration and distribution fee, see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGES
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to its investment adviser. These
charges and other Fund charges and expenses are fully described in the
prospectuses for the Funds. These charges indirectly cost you because they lower
your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.
 
                                                                              25

- --------------------------------------------------------------------------------
 
REDUCTION OR WAIVER OF ACCOUNT
MAINTENANCE FEE, SURRENDER,
MORTALITY AND EXPENSE RISK FEE OR ADMINISTRATION AND DISTRIBUTION FEE CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender
charges, mortality and expense risk fee or administration fee for Portfolio
Director 2 may be reduced or waived. We may reduce or waive these fees and
charges if we determine that your retirement program will allow us to reduce or
eliminate administrative or sales expenses that we usually incur for retirement
programs. There are a number of factors we will review in determining whether
your retirement program will allow us to reduce or eliminate these
administrative or sales expenses:
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
  We review the following additional factors to determine whether we can reduce
  or waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review to following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
  We review the following additional factors to determine whether we can reduce
  or waive the mortality and expense fee or administration and distribution fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
  We will only do this if permitted by this Contract and by VALIC guidelines in
  effect at the time. In no event will the reduction or waiver of fees and
  charges be permitted where the reduction or waiver will unfairly discriminate
  against any person.
 
  SEPARATE ACCOUNT EXPENSE
  REIMBURSEMENT
 
  Some of the Mutual Funds or their affiliates may have an agreement with the
  Company to pay the Company for certain administrative and shareholder services
  it provides to the underlying Fund. The Company will reduce its charges to the
  Division investing in that Fund by the full amount of any of these payments it
  receives. In addition, the Company currently reimburses certain Divisions a
  portion of the Company's administration and distribution fee. Such
  reimbursement arrangements are a voluntary. See the Fee Table in this
  prospectus for an identification of those Funds for which a reimbursement
  applies.

<PAGE>   427
 
PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
(1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
   
With a Variable Payout, you may select from your existing Variable Account
Options. Your payments will vary accordingly. This is due to the varying
investment results that will be experienced by each of the Variable Account
Options you selected. The Payout Unit Value is calculated just like the Purchase
Unit Value for each Variable Account Option except that the Payout Unit Value
includes a factor for the Assumed Investment Rate you select. For additional
information on how Payout Payments and Payout Unit Values are calculated, see
the Statement of Additional Information.
    
 
   
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the
    
Variable Account Option is lower than your Assumed Investment Rate, your next
payment will be less than your first payment.
 
COMBINATION FIXED AND VARIABLE
PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
   
Up to seven Variable Account Options may be chosen, or up to six Variable
Account Options if the Fixed Payout is chosen.
    
 
PAYOUT DATE
The Payout Date is the date elected by you on which your payout (annuity)
payments will start. The date elected must be the first of any month provided 30
days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              27
<PAGE>   428
 
- --------------------------------------------------------------------------------
 
    - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
      lifetime. Upon your death, your beneficiary will receive a lump sum
      payment equal to the remaining Annuity Value.
 
    - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
      lifetime of you and your beneficiary. Upon the death of one, payments
      continue during the lifetime of the survivor. This option is designed
      primarily for couples who require maximum possible variable payouts during
      their joint lives and are not concerned with providing for beneficiaries
      at death of the last survivor. For example, it would be possible under
      this option for the Joint Annuitants to receive only one payment if both
      Annuitants died prior to the date of the second payment, or for the Joint
      Annuitants to receive only one payment and the surviving Annuitant to
      receive only one payment if one Annuitant died prior to the date of the
      second payment and the surviving Annuitant dies prior to the date of the
      third payment.
 
    - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
      number of years between five and thirty. Upon your death, payments will
      continue to your beneficiary until the designated period is completed.
 
ENHANCEMENTS TO PAYOUT OPTIONS
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. The Joint and Survivor
Life Option may be available with a one to twenty year guaranteed period option.
Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
   
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
    
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option, and
 
   
  - The payments will be guaranteed for a 10 year period,
    
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
   
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis, and
    
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
   
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or plan.

PAYOUT OPTIONS OR
ENHANCEMENTS

available under the Contract,

Additional Information".

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.
 
AMOUNT THAT MAY BE SURRENDERED
The amount that may be surrendered at any time can be determined as follows:
 
<TABLE>
<S>                    <C>               <C>
                                               Your
                                              Account
       Allowed                               Value(1)
      Surrender           = (EQUALS)         - (MINUS)
        Value                             Any Applicable
                                             Surrender
                                              Charge
</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
   
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See your current Fund(s)' prospectuses
for a discussion of the reasons why the redemption of shares may be suspended or
postponed.
    
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
 
Under the FLORIDA STATE OPTIONAL RETIREMENT PROGRAM, no surrender or partial
surrender of Purchase Payments made by the employer will be allowed except for
termination of employment, retirement or death. Benefit payments based on
payments from the employer may not be paid in a lump sum or for a period
certain, but must be paid under a life contingency option, except for:
 
  - death benefits; and
 
  - certain small amounts approved by the State of Florida.
 
   
Under the LOUISIANA OPTIONAL RETIREMENT PLAN retirement benefits must be paid in
the form of a lifetime income, and except for death benefits, single sum
surrenders and partial surrenders out of the plan are not permitted.
    
 
   
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
    
 
   
PARTIAL SURRENDERS
    
   
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Options first unless otherwise specified by you.
    
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director 2. There will be no surrender charge for withdrawals using this method,
which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
 
                                                                              29
<PAGE>   430
 
- --------------------------------------------------------------------------------
 
revoked, a systematic withdrawal may not be elected again. No more than one
systematic withdrawal election may be in effect at any one time. We reserve the
right to discontinue any or all systematic withdrawals or to change its terms,
at any time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW. There will be no surrender charge on
a minimum distribution required by federal tax law (known as No Charge Minimum
Distribution), if the withdrawal:
 
  - Is made payable to you; and
 
  - Does not exceed the amount required under federal tax law as determined by
    the values in your Portfolio Director 2 Contract and VALIC.
 
This contract feature will not be available in any year that an amount has been
withdrawn under the no charge systematic withdrawal method. See "Federal Tax
Matters" in this prospectus and in the Statement of Additional Information for
more information about required distributions imposed by tax law.
 
For an explanation of possible adverse tax consequences of a surrender, see
"Federal Tax Matters" in this prospectus and in the Statement of Additional
Information.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
   
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director 2. These other contracts are listed below. We
will allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director 2. This exchange privilege will be available
only to other contracts purchased through your employer-sponsored retirement
plan and for which we have not yet started making payments under a Payout
Option. If you elect to exercise one of these exchange offers, you should
contact any of our Regional Offices at the addresses shown in the back of this
prospectus. An exchange may require the issuance of a Contract or may be subject
to any other requirements that the Company may impose.
    
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
   
  - Exchanges from Portfolio Director 2 to contract forms other than Portfolio
    Director Plus are not permitted.
    
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director 2. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director 2. For example, you
will be subject to the rules concerning transfers among investment options as
stated in the Transfers Between Investment Options section in this prospectus.
We may, at our option, waive any transfer restrictions for a stated period of
time. If we waive these transfer restrictions, you will be allowed to exchange
to any investment option available in Portfolio Director 2.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director 2.
 
SURRENDER CHARGES
 
We will generally not impose nor waive existing surrender charges as a result of
your electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director 2 will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director 2, the
contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director 2 will be the same date as the other contract, but no
earlier than January 1, 1982. (The effect of this is to potentially shorten the
charge period for Purchase Payments subsequently made to Portfolio Director 2.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director 2 for purposes of calculating the surrender charge. The effective dates
of these Purchase Payments will also be retained for surrender charge purposes.
 
The Portfolio Director 2 surrender charge is calculated assuming the most recent
Purchase Payments are removed first. This policy may cause exchanged funds to be
accessible only after charges are imposed.

AGENTS' AND MANAGERS' RETIREMENT PLAN
EXCHANGE OFFER
 
General. All eligible agents and managers of the Company are allowed to
participate in the Company's Agents' and Managers' Retirement Plan ("Plan"). We
grant to participants in the Plan the right to effect a voluntary exchange of
their units of interest under the SA-1 Contracts, Independence Plus Contracts
and Portfolio Director for the equivalent units of interest in Portfolio
Director 2.
 
Agents and managers of VALIC who enter into the voluntary exchange will not
incur under Portfolio Director 2 any surrender charges or account maintenance
fees. Other individuals who may exchange to Portfolio Director 2 from SA-1,
Independence Plus or Portfolio Director Contracts may have surrender charges and
account maintenance fees imposed under Portfolio Director 2. All other
provisions with regard to exchange offers referenced in the section entitled
"Exchange Offers" will apply to the Agents' and Managers' Retirement Plan
Exchange Offer.
 
Pursuant to this voluntary exchange offer, participants in the Plan will have
three options to choose from. As to the funding vehicle for
 
 32
<PAGE>   433
 
- --------------------------------------------------------------------------------
 
their purchase payment plan, the participant may choose to:
 
  - Remain in the SA-1 Contract, Independence Plus Contract or Portfolio
    Director.
 
  - Leave current assets in the SA-1 Contract, Independence Plus or Portfolio
    Director and direct future Purchase Payments to Portfolio Director 2; or
 
  - Transfer all current assets and future Purchase Payments to Portfolio
    Director 2.
 
If the participant chooses to remain in either the SA-1 Contract, Independence
Plus Contract or Portfolio Director, future Purchase Payments and current assets
will be controlled by the provisions of the SA-1 Contract, Independence Plus
Contract or Portfolio Director, respectively. If the participant chooses to
leave current assets in the SA-1 Contract, the Independence Plus Contract or
Portfolio Director and direct future Purchase Payments to Portfolio Director 2,
the current assets will be controlled by the provisions of the SA-1 Contract,
the Independence Plus Contract or Portfolio Director, respectively. The future
Purchase Payments will be controlled by the terms of Portfolio Director 2
subject to the exception that surrender charges and account maintenance fees
will not be imposed under Portfolio Director 2. If the participant chooses to
transfer all current assets and future Purchase Payments to Portfolio Director
2, such current assets and future Purchase Payments will be controlled by the
provisions of Portfolio Director 2 subject to the exception that surrender
charges and account maintenance fees will not be imposed under Portfolio
Director 2.
 
   
Once a participant transfers assets and future Purchase Payments to Portfolio
Director 2 the participant will not be permitted to exchange back to the SA-1
Contract or Independence Plus Contract. See "Exchange Offer for Portfolio
Director and Portfolio Director 2" in this prospectus. If a participant chooses
to transfer future Purchase Payments but not current assets to Portfolio
Director 2, the participant will be allowed at a later date to transfer the
current assets to Portfolio Director 2. For a complete analysis of the
differences between the SA-1 contract, the Independence Plus Contract or
Portfolio Director and Portfolio Director 2, you should refer to the Statement
of Additional Information and the form of the contract or certificate for its
terms and conditions.

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director 2 will pay death benefits during either the Purchase Period
or the Payout Period. How these death benefits will be paid are discussed below.
The death benefit provisions in Portfolio Director 2 may vary from state to
state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
- - In a lump sum; or
 
- - In the form of an annuity under any of the Payout Options stated in the Payout
  Period section of this prospectus subject to the restrictions of that Payout
  Option.
 
   
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
    
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
- - In full within 5 years after the Annuitant's death; or
 
- - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
   
  - An annuity for a designated period not exceeding the Beneficiary's life
    expectancy.
    
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director 2.
 
SPECIAL INFORMATION FOR INDIVIDUAL
NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the Annuitant's death. However, the Contract
will be transferred to the Contingent Owner,
if any, or to the Contract Owner's estate. Such transfers will be considered a
taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:
Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Fixed Account Option on date
  proof of death Is received by VALIC
  OR
  100% of Purchase Payments placed
  in Fixed Account Option
- - (minus)
  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
</TABLE>
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Variable Account Option on date
  proof of death is received by VALIC
  OR
  100% of Purchase Payments placed in
  Variable Account Options
- - (minus)
  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option
+ (plus)
  Interest at an annual rate of 3%
</TABLE>
 
Step 3: Add step 1 + 2 = Death Benefit
 
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
BENEFICIARY -- the person
designated to receive Payout
Payments upon the death of
an Annuitant.
 
ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid.
 
   
CONTRACT OWNER -- either
    
   
your employer or organization
    
   
in the case of a group
    
   
contract or the Annuitant in
    
   
the case of an individual
    
   
contract. If the contract is an
    
   
individual non-qualified type,
    
   
this is generally the Annuitant
    
   
but is not required to be.
    
   
Also, a Contingent Contract Owner
    
   
may be designated.
    
 
FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options. Currently,
the Fixed Account Options in
Portfolio Director 2 are Fixed
Account Plus and Short-Term
Fixed Account. Each option
of this type is guaranteed to
earn at least a minimum rate
of interest.
 
   
VARIABLE ACCOUNT
    
OPTIONS -- investment
options that correspond to
VALIC Separate Account A
Divisions offered by Portfolio
Director 2. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.
 
 34
<PAGE>   435
 
- --------------------------------------------------------------------------------
 
STANDARD DEATH BENEFIT
 
The standard death benefit is payable if death occurs on or after age 70.
 
The Standard Death Benefit will be the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Your Account Value on the Date Proof of Death is
  Received by VALIC
  OR
  100% of Purchase Payments (to Fixed
  and/or Variable Account Options)
- -- (MINUS)
  Amount of all Prior Withdrawals, Charges
  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director 2 are described in the "Payout Period" section
of this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed
       period option chosen by the deceased Participant; or
 
     - Receive the present value of any remaining payments applied under the
       Payment for a Designated Period Option for a period equal to or shorter
       than the period remaining. Spouse beneficiaries may be entitled to more
       favorable treatment under federal tax law.
 
                                                                              35

HOW TO REVIEW INVESTMENT PERFORMANCE
OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
   
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts or to the general public
before Portfolio Director 2 was first available to you. We may therefore,
advertise investment performance since the inception of the underlying Funds. In
each case, we will use the charges and fees imposed by Portfolio Director 2 in
calculating the Division's investment performance for earlier time frames.
    
 
TYPES OF INVESTMENT PERFORMANCE
INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE
INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Standard Average Annual Total Return shows the average percentage change in the
value of an investment in the Division from the beginning to the end of a given
historical period. The results shown are after all charges and fees have been
applied against the Division. This will include account maintenance fees and
surrender charges that would have been deducted if you surrendered Portfolio
Director 2 at the end of each period shown. Premium taxes are not deducted. This
information is calculated for each Division based on how an initial assumed
payment of $1,000 performed at the end of 1, 3, 5 and 10 year periods. If
Standard Average Annual Return for a Division is not available for a stated
period, we may show the Standard Average Annual Return since Division inception.
    
 
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
 
NONSTANDARD AVERAGE ANNUAL TOTAL
RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance information of an underlying Fund
reduced by Account fees for a period prior to the inception of the corresponding
Division is nonstandard performance information regardless of whether all
account fees and charges are deducted.
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director 2 will stay
in the Division beyond the time that a surrender charge would apply. It may be
calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
   
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the
 
DIVISIONS -- subaccounts of
    
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director 2. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director 2.
 
For more information on how
TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.
 
 36
<PAGE>   437
 
- --------------------------------------------------------------------------------
 
Division's Annual Change in Purchase Unit Value.
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT
INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director 2 charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC MONEY MARKET DIVISION
 
We may advertise the AGSPC Money Market Division's Current Yield and Effective
Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market Division over a given 7-day period. The Current Yield does not take
into account surrender charges, account maintenance fees or premium taxes. The
income produced over a 7 day period is then "annualized." This means we are
assuming the amount of income produced during the 7-day period will continue to
be produced each week for an entire year. The annualized amount is shown as a
percentage of the investment. The annualized 7-day Current Yield for the last 7
days ended December 31, 1998 was 4.04%.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause the Effective Yield to be higher than the Current
Yield. The annualized 7-day Effective Yield for the last 7 days ended December
31, 1998 was 4.12%.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET DIVISION
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market Division. The yield for each of these Divisions will be
determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION:
 
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
   
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate Account A
Division is printed in the six tables below.

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director 2
was issued in connection with a nonqualified and unfunded deferred compensation
plan.
 
DETERMINATION OF FUND SHARES
ATTRIBUTABLE TO YOUR ACCOUNT
 
DURING PURCHASE PERIOD
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
DURING PAYOUT PERIOD OR AFTER A DEATH
BENEFIT HAS BEEN PAID
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director 2
may have a number of shareholders including VALIC Separate Account A, VALIC
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies and public shareholders.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
   
VALIC Separate Account A will vote the shares of the Funds it holds based on,
and in the same proportion as, the voting instructions received from
participants in VALIC Separate Account A.
    
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.
 
VALIC SEPARATE
ACCOUNT A -- a segregated
asset account established by
VALIC under the Texas
Insurance Code. The purpose
of VALIC Separate Account A

FEDERAL TAX MATTERS
- --------------------------------------------------------------------------------
 
Portfolio Director 2 provides tax-deferred accumulation over time, but is
subject to federal income and excise taxes, mentioned briefly below. You should
refer to the Statement of Additional Information for further details. Section
references are to the Internal Revenue Code ("Code"). We do not attempt to
describe any potential estate or gift tax, or any applicable state, local or
foreign tax law other than possible premium taxes mentioned under "Premium Tax
Charge." Remember that future legislation could modify the rules discussed
below, and always consult your personal tax adviser regarding how the current
rules apply to your specific situation.
 
TYPE OF PLANS
 
   
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program or 408(b) IRA, as a Section 408(b)
Individual Retirement Annuity ("IRA"), or is instead a nonqualified Contract.
Portfolio Director 2 is used under the following types of retirement
arrangements:
    
 
  - Section 403(b) annuities for employees
     of public schools and
     Section 501(c)(3) tax-exempt
     organizations;
 
  - Section 401(a) and 403(a) qualified plans of for-profit employers and other
    employers (including self-employed individuals);
 
   
  - Section 408(b) IRAs;
    
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
   
  - Section 408(k) SEPs.
    
 
  - Section 408(p) SIMPLE retirement
     accounts.
 
   
The foregoing Contracts are "Qualified Contracts." Certain series of Portfolio
Director 2 may also be available through a nondeductible Section 408A "Roth"
individual retirement annuity ("Roth IRA").
    
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
   
In addition, Portfolio Director 2 is also available through "Non-Qualified
Contracts" to the extent acquired by "Non-Natural Persons." Such Non-Qualified
Contracts generally include unfunded, nonqualified deferred compensation plans
of corporate employers as well as individual annuity contracts issued to
individuals outside of the context of any formal employer or employee retirement
plan or arrangement. Non-Qualified Contracts generally may invest only in mutual
funds which are not available to the general public outside of annuity contracts
or life insurance contracts.
    
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director 2 can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Qualified Contracts receive deferral of tax on
the inside build-up of earnings on invested Purchase Payments, until a
distribution occurs. See the Statement of Additional Information for special
rules, including those applicable to taxable, non-natural owners of
Non-Qualified Contracts.
 
   
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
    
 
Distributions are taxed differently depending on the program through which
Portfolio Director 2 is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
   
Amounts subject to income tax may also incur excise tax or penalty taxes, under
the circumstances described in the Statement of Additional Information.
Generally, they would also be subject to some form of federal income tax
withholding unless rolled into another tax-deferred vehicle. Required
withholding will vary according to type of program, type of payment and your tax
status. In addition, amounts received under all Contracts may be subject to
state income tax withholding requirements.
    
 
                                                                              43
<PAGE>   444
 
- --------------------------------------------------------------------------------
 
It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if purchase payments under the contract are invested in
publicly available mutual funds. In a ruling published in 1981, the Internal
Revenue Service ("IRS") had taken the position that, where purchase payments
under a variable annuity contract are invested in publicly available mutual
funds, the contract owner should be treated as the owner of the mutual fund
shares, and deferred tax treatment under the contract should not be available.
In the opinion of VALIC and its tax counsel, the 1981 ruling has been superseded
   
by subsequent legislation (Code Section 817(h)) which specifically exempts these
Qualified Contracts, and the IRS has no viable legal basis or reason to apply
the theory of the 1981 ruling to these Qualified Contracts under current law.
Although VALIC can provide no assurance that the IRS will not challenge the
deferred tax treatment of these Qualified Contracts under the theory of the 1981
ruling, VALIC and its tax counsel believe that Contract owners would prevail if
such a challenge were made.
    
 
   
It is also the opinion of VALIC and its tax counsel that for each other type of
Qualified Contract an independent exemption provides tax deferral regardless of
how ownership of the Mutual Fund shares might be imputed for Federal income tax
purposes.
    
 
   
Investment earnings on contributions to Non-Qualified Contracts which are not
owned by natural persons will be taxed currently to the owner and such contracts
will not be treated as annuities for federal income tax purposes.
    
 
EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director 2 Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
 
                        THE POWER OF TAX-DEFERRED GROWTH
                                  [BAR GRAPH]
 
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. The deduction of
fees and charges for both tax-deferred plans is reflected in the chart. Variable
options incur mortality and expense risk fee and administration and distribution
fee charges (0.60% - 0.85% during the purchase period and 1% - 1.25% during the
payout period) and may also incur account maintenance fees ($3.75 per quarter)
and surrender charges (5% of the lesser of all contributions received during the
last 60 months or the amount withdrawn). The dotted lines represent the amounts
remaining after withdrawal and payment of taxes and any surrender charge. An
additional 10% tax penalty may apply to withdrawals before age 59 1/2. This
information is for illustrative purposes only and is not a guarantee of future
return.
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.

To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE
REDUCED BY THE IMPACT OF INCOME TAXES UPON WITHDRAWAL. The yield will vary
depending upon the timing of withdrawals. The previous chart represents (without
factoring in fees and charges) after-tax amounts that would be received.
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

</TABLE>
 
This chart assumes a 28% federal income tax rate. The $700 which is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800, while the full $2,500 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a tax-
qualified retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-qualified retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
   
YEAR 2000 RISKS
    
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
  - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
    Problem. This plan includes the five steps that we believe are essential to
    Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or
    replace systems that are not Year 2000 ready; (4) test systems to prove that
    they will work correctly into the year 2000; and (5) return the systems to
    operations. As of December 31, 1998, we have substantially completed all
    steps with respect to our critical systems.
    
 
   
  - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that
    must also be Year 2000 ready. Third parties are companies that provide
    certain services to VALIC. Third parties are different from internal systems
    in that VALIC has less, or no, control over their Year 2000 readiness. VALIC
    has developed a plan to review and try to lessen the Year 2000 risks of
    third parties. As of December 31, 1998, VALIC has substantially completed
    its review of third party Year 2000 risks. VALIC intends to test third party
    Year 2000 readiness throughout 1999.
    
 
   
  - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
    associated with the Year 2000 Problem. The contingency plans for third party
    relationships include the following activities: (1) evaluate the
    consequences of any failures associated with the Year 2000 Problem; (2)
    determine the chance of a Year 2000-related failure for systems that have a
    high chance of failing; (3) develop an action plan to complete contingency
    plans for those systems that rank high in both impact of failure and chance
    of failure; and (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.

The Variable Annuity Life Insurance Company ("VALIC") offers certain series of

Portfolio Director T permits you to invest in and receive retirement benefits in
up to 2 Fixed Account Options and/or an array of up to 10 Variable Account
Options. Each of these investment options is explained more fully in this
prospectus. If your contract is part of your employer's retirement program, that
program will describe which Variable Account Options are available to you. If
your contract is a tax-deferred nonqualified annuity that is not part of your
employer's retirement plan, those Variable Account Options that are invested in
Mutual Funds available to the public outside of annuity contracts, life
insurance contracts, or certain employer-sponsored retirement plans will not be
available within your contract. Here is a list of these investment options:

(3) The mortality and expense risk fee and administration and distribution fee
    reflected in the Fee Table is deducted during the Purchase Period. The
    mortality and expense risk fee and administration and distribution fee
    deducted during the Payout Period is computed at an annualized rate of
    1.00%, depending upon the Variable Account Option selected.
    
 
   
(4) For Scudder Growth and Income Fund the Total Separate Account Fee equals the
    VALIC Separate Account A mortality and expense risk fee plus the
    administration and distribution fee reduced by the Separate Account Expense
    Reimbursement. Pursuant to the Separate Account Expense Reimbursement the
    Company's charges to this Division are reduced by an amount equal to
    payments (0.25%) from the underlying Fund and/or its affiliate for
    administrative and shareholder services provided by the Company. See "Fees
    and Charges -- Separate Account Expense Reimbursement" in this prospectus
    for more information.
    
 
   
(5) For these Funds the Total Separate Account Fee equals the VALIC Separate
    Account mortality and expense risk fee plus the administration and
    distribution fee reduced by the Separate Account Expense Reimbursement. The
    Separate Account Expense Reimbursement reflects a voluntary expense
    reimbursement made by the Company directly to the Division, which may be
    terminated by the Company at any time without notice.
    
 
   
(6) OTHER EXPENSES includes custody, accounting, reports to shareholders, audit,
    legal and other miscellaneous expenses. See each Fund's prospectus for a
    detailed explanation of these fees.
    
 
   
(7) The AGSPC Asset Allocation Fund was formerly known as the Timed Opportunity
    Fund. The Vanguard Long-Term Corporate Fund was formerly known as the
    Vanguard Fixed Income Securities Fund -- Long-Term Corporate Portfolio
    Division. The Vanguard Long-Term Treasury Fund was formerly known as the
    Vanguard Fixed Income Securities Fund -- Long-Term U.S. Treasury Portfolio.

(1)  Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of Bankers Trust Corporation. On November 30, 1998,
     Bankers Trust Corporation entered into an Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
     Corporation and all of its subsidiaries would merge with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a
     major global banking institution that is engaged in a wide range of financial services, including retail and commercial
     banking, investment banking and insurance. The merger is contingent upon various regulatory approvals. On April 20, 1999,
     the Fund's Board of Directors approved a new investment sub-advisory agreement with Bankers Trust Company, subject to
     shareholder approval. If the merger is approved and completed, Deutsche Bank AG, as the Sub-Adviser's new parent company,
     will control the operations of the Sub-Adviser. Bankers Trust believes that, under this new arrangement, the services
     provided to the Fund will be maintained at their current level.

SUMMARY -- (CONTINUED)
    
- --------------------------------------------------------------------------------
 
   
A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
    
 
INTEREST GUARANTEED DEATH BENEFIT
Portfolio Director T offers a death benefit with an interest guarantee when
death occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director T offers a tax-free loan provision for tax-qualified
contracts that gives you access to your money in either of the Fixed Account
Options, subject to a minimum loan amount of $1,000. The availability of loans
is subject to government regulations, as well as your employer's plan
provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e. loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
There is no charge to transfer the money in your account among Portfolio
Director T's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is
computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you have withdrawn. The second amount is
5% of the contributions you made to your account during the last 60 months.
 
Withdrawals are always subject to your plan provisions and federal tax
restrictions, which generally include a tax penalty on withdrawals made prior to
age 59 1/2.
 
PREMIUM TAX CHARGE
   
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
    
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
aggregate annualized rate of 0.80% during the purchase period and 1.00% during
the payout period on the average daily net asset value of VALIC Separate Account
A. Reductions in the mortality and expense risk fee and administration and
distribution fee may be available for plan types meeting certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.
 
SEPARATE ACCOUNT EXPENSE REIMBURSEMENT
   
The Company will reimburse to certain Divisions any fees it receives from the
Mutual Fund or its affiliate or distributor for providing the Mutual Fund
administrative and shareholder services. In addition, the Company currently
reimburses certain Divisions a portion of the Company's administration and
distribution fee for providing Variable Account Options. Such reimbursement
arrangements are voluntary. For more information as to which Variable Account
Options have a Separate Account Expense Reimbursement see the Fee Table.
    
 
PAYOUT OPTIONS
When you withdraw your money, you can select from several payout options: a
lifetime annuity (which guarantees payment for as long as you live), periodic
withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.
 
FEDERAL TAX INFORMATION
Although deferred annuity contracts such as Portfolio Director T can be
purchased with after-tax dollars, they are primarily used in connection with
retirement programs which receive favorable tax treatment under federal law.
 
PURCHASE REQUIREMENTS
Purchase Payments may be made at any time and in any amount, subject to plan
limitations.
 
To learn more about the
INTEREST GUARANTEED DEATH
BENEFIT, refer to the section
in the prospectus entitled
"Death Benefits."
 
More information on FEES
may be found in the
prospectus under the
headings "FEES AND
CHARGES" AND "FEE TABLE."

discussion of these income
tax provisions, see the
"FEDERAL TAX MATTERS"
section of the prospectus and

Information.

(1) Effective with the merger of Quality Growth Fund into Stock Index Fund on
    May 1, 1992, Quality Growth Division 9 was merged into Stock Index Division
    10. The merger of Divisions was accomplished by an exchange of units of
    Quality Growth Division 9 for units of Stock Index Division 10 of equivalent

    Purchase units shown are for a Purchase Unit outstanding throughout the year
    under a representative Contract of the type invested in each column shown.
    The unit value of each Division of VALIC Separate Account A will not be the
    same on any given day as the net asset value per share of the underlying
    Fund of the Series Company and the other mutual fund portfolios described in
    this prospectus in which that Division invests. This is because each unit
    value consists of the underlying share's net asset value minus the charges
    to VALIC Separate Account A. In addition, dividends declared by the
    underlying Fund are reinvested by the Division in additional shares. These
    distributions have the effect of reducing the value of each share of the
    Fund and increasing the number of Fund shares outstanding. However, the
    total cash value in VALIC Separate Account A does not change as a result of
    such distributions.

ABOUT VALIC SEPARATE ACCOUNT A
 
When you direct money to Portfolio Director T's Variable Account Options, you
will be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director T. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account.
 
VALIC Separate Account A is made up of what we call "Divisions." Ten Divisions
are available and represent the Variable Account Options in Portfolio Director
T. Each of these Divisions invests in a different Mutual Fund made available
through Portfolio Director T. For example, Division Ten represents and invests
in the Stock Index Fund. The earnings (or losses) of each Division are credited
to (or charged against) the assets of that Division, and do not affect the
performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25, 1979 under Texas insurance law
to allow you to be able to invest in a number of Variable Account Options
available in Portfolio Director T. VALIC Separate Account A is registered with
the Securities and Exchange Commission (SEC) as a unit investment trust under
the Investment Company Act of 1940 ("Act"). Units of interest in VALIC Separate
Account A are registered as securities under the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director T, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director T, the
Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director T be held exclusively for the benefit of the
contract owner, participants, annuitants, and beneficiaries of Portfolio
Director T. When we discuss performance information in this prospectus, we mean
the performance of a VALIC Separate Account A Division.
 
UNITS OF INTERESTS
 
Your investment in a Division of VALIC Separate Account A is represented by
units of interest issued by VALIC Separate Account A. On a daily basis, the
units of interest issued by VALIC Separate Account A are revalued to reflect
that day's performance of the underlying

VARIABLE ACCOUNT OPTIONS
- --------------------------------------------------------------------------------
 
   
Portfolio Director T enables you to participate in Divisions that represent ten
Variable Account Options. These Divisions comprise all of the Variable Account
Options that are made available to you through VALIC Separate Account A.
According to your retirement program, you may not be able to invest in all ten
Variable Account Options described in this prospectus. See "About VALIC Separate
Account A" in this prospectus.
    
 
Each individual Division represents and invests, through VALIC's Separate
Account A, in specific mutual funds. Three of the Mutual Funds are also
available to the general public. These mutual funds serve as the investment
vehicles for Portfolio Director T and include:
 
- - American General Series Portfolio
   
  Company (AGSPC) -- offers 7 funds, for which VALIC serves as investment
  adviser, for 2 of such funds, Banker Trust Company serves as investment
  sub-adviser and for 2 of such funds, T. Rowe Price & Associates, Inc. serves
  as investment sub-adviser.
    
 
- - Scudder Kemper Investments, Inc. -- offers 1 fund for which Scudder Kemper
  Investments, Inc. serves as investment adviser.
 
- - The Vanguard Group Inc. -- offers 2 funds for which Vanguard Fixed Income
  Group serves as investment adviser.
 
   
Three of the Mutual Funds are also available to the general public.
    
 
Each of these Funds is registered as a diversified open-end, management
investment company and is regulated under the Investment Company Act of 1940.
For complete information about each of these Funds, including charges and
expenses, you should refer to the prospectus for that Fund. Additional copies
are available from VALIC or you may contact your VALIC Regional Office at the
addresses shown in the back of this prospectus.
 
SUMMARY OF FUNDS
 
   
A brief summary of the investment objectives of each Mutual Fund is shown below.
In addition to the investment objectives, the Account Value of an assumed
$10,000 investment in each of the Divisions is shown in both table and graph
form as well as the Standard Average Annual Total Return for a 1, 3, 5 and 10
year period, if available. If Standard Average Annual Return for a Division is
not available for a stated period, we may show the Standard Average Annual
Return since Division inception. The performance information in the tables and
graphs will reflect a deduction for separate account fees (mortality and expense
risk fees plus administration and distribution fees minus any applicable
reimbursements) and underlying fund charges. They will not reflect any deduction
for account maintenance fees, surrender charges and premium taxes. These charges
would further reduce your return. The Account Values in the graphs shown reflect
Separate Account performance based on the performance of the underlying Fund for
the last 10 fiscal years or, since inception of the underlying Fund if for less
than 10 years. The returns shown in the tables reflect for the AGSPC Funds
actual historical performance of the related Separate Account Divisions. The
returns shown in the tables for certain Funds (Divisions 21-23) reflect actual
historical performance of the related Separate Account Divisions since inception
of each Division (July 1, 1996) and hypothetical performance for periods prior
to July 1, 1996. Hypothetical performance is based on the actual performance of
the underlying Fund reduced by Separate Account fees that would have been
incurred during the hypothetical period. Investment return and principal value
will fluctuate with market conditions, and for foreign investments, currencies
and the economic and political climates of the countries where investments are
made. Past performance cannot predict or guarantee future results.
    
 
   
The Standard Average Annual Total Return figures show the average percentage
change in the value of an investment in a Division from the beginning to the end
of the historical periods shown below. The results shown are after all charges
and fees have been applied against the Division. This will include account
maintenance fees and surrender charges that would have been deducted if you
surrendered Portfolio Director T at the end of the specified period. Premium
taxes are not deducted. This information is calculated for each Division based
on how an initial investment of $1,000 performed at the end of the specified
periods shown.
    
 
For more information about how these returns were calculated including a
statement of the charges reflected and tables showing historical performance
information see "How to Review Investment Performance of Separate Account
Divisions" in this prospectus.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director T account is surrendered before the Payout Period. The
amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director T was purchased.
 
PURCHASE PAYMENTS
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account.
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>
<CAPTION>
                         Initial    Subsequent
     Contract Type       Payment     Payment

Periodic Payment         $   30        $ 30
Single Payment           $1,000         -0-
</TABLE>
 
   
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
    
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
   
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments within 5 business days if the requested information is not
  provided, unless you otherwise so specify.
    
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under these circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment
 
  in an "Employer-Directed" account invested in our Money Market Division
  Option. You may not transfer these amounts until VALIC has received a
  completed application or enrollment form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  Money Market Division. We will send you follow-up letters requesting the
  information necessary to complete the application, including your allocation
  instructions. Unless a completed application or enrollment form is received by
  us within 105 days of establishment of your starter account, the account
  balance, including earnings, will be returned to your employer. We are not
  responsible for any adverse tax consequences to you that may result from the
  return of your employer's contributions.
 
PURCHASE UNITS
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
The Purchase Unit value for a Division is calculated as shown below:
Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income and capital gains and losses (whether
  realized or unrealized) on that day from the assets attributable to the
  Division.
/ (DIVIDED BY)
  The value of the Division for the immediately preceding day on which the
  values are calculated.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director T.
 
   
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.
    

For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.
 
                                                                              15
<PAGE>   473
 
   
    
- --------------------------------------------------------------------------------
 
We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the New York Stock Exchange is open.
Step 2: Calculate net investment rate for any day as follows:
 
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
 
  Purchase Unit Value for that day.
= (EQUALS)
  Purchase Unit Value for immediate preceding day.
X (MULTIPLIED BY)
  Net Investment Rate (as calculated in Step 2) plus 1.00.
 
CHOOSING INVESTMENT OPTIONS
 
There are 12 investment options offered in Portfolio Director T. This includes 2
Fixed Account Options and 10 Variable Account Options. Unless provided
otherwise, you
may select and combine up to 7 of the 10 options. The Funds that underlie the
Variable Account Options are registered as investment companies under and are
subject to regulation of the Investment Company Act of 1940 (the Act). The Fixed
Account Options are not subject to regulation under the Act and are not required
to be registered under the Securities Act of 1933. As a result, the SEC has not
reviewed data in this prospectus that relates to the Fixed Account Options.
However, federal securities law does require such data to be accurate and
complete.
 
FIXED ACCOUNT OPTIONS
 
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in "Summary" appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed Account Options
= (EQUALS)
  All Purchase Payments made to the Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable Account Options to the Fixed Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn from Fixed Account Options (including
  applicable fees and charges)
 
VARIABLE ACCOUNT OPTIONS
 
   
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. A complete discussion of each of the Variable Account Options may be
found in the "Variable Account Options" section in this prospectus. Based upon a
Variable Account Option's Purchase Unit Value your account will be credited with
the applicable number of Purchase Units. The Purchase Unit Value of each
Variable Account Option will change daily depending upon the investment
performance of the underlying fund (which may be positive or negative) and the
deduction of VALIC Separate Account A charges. See the "Fees and Charges"
section in this prospectus. Because Purchase Unit Values change daily, the
number of Purchase Units your account will be credited with for subsequent
Purchase Payments will vary. Each Variable Account Option bears its own
investment risk. Therefore, the value of your account may be worth more or less
at retirement or withdrawal.
    
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
 
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director T account has been surrendered. The
value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
   
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any
such account closure will be subject to applicable distribution restrictions
under the Contract and/or under your employer's plan.
    
 
   
PURCHASE UNIT -- a measuring unit used
to calculate your
Account Value during the
Purchase Period. The value
of a Purchase Unit will vary
with the investment
experience of the Separate
Account Division you have
selected.

TRANSFERS BETWEEN INVESTMENT OPTIONS
- --------------------------------------------------------------------------------
 
You may transfer all or part of your Account Value between the various Fixed
Account and Variable Account Options in Portfolio Director T without a charge.
Transfer instructions may be made either in writing or by telephone as discussed
below. Transfers may be made during the Purchase Period or during the Payout
Period. We reserve the right to limit transfers as discussed below. Your
employer's plan may also limit your rights to transfer.
 
DURING THE PURCHASE PERIOD
During the Purchase Period, transfers may be made between Portfolio Director T's
Fixed Account Options and Variable Account Options.
 
We currently permit transfers between Variable Account Options or from Variable

COMMUNICATING TRANSFER OR REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director, should be
sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
   
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
    
 
- - The next date values are calculated.
 
ACCOUNT VALUE -- the total
sum of your Fixed Account
and/or Variable Account
Options that have not yet
been applied to your Payout
Payments.
 
PURCHASE PERIOD -- the time
between your first Purchase
Payment and your Payout
Period (or surrender).
 
HOME OFFICE -- Our
principal office at 2929 Allen
Parkway, Houston, Texas
77019.
 
PAYOUT PERIOD -- the time
that starts when you begin to
withdraw your money in a
steady stream of payments.

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director T, you may be subject to six basic types of
fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director T is issued to certain types of plans which are expected to result in
lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
   
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
    
 
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is actually withdrawn. We
consider all Purchase Payments to be withdrawn before earnings are withdrawn.
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

- --------------------------------------------------------------------------------
 
- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy of a Social Security Administration determination or a doctor's
  verification; or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director T is issued
to certain types of plans which are expected to result in lower costs to VALIC.
To learn more about how we determine if a surrender charge may be reduced or
waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
   
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
    
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an aggregate annualized rate of 0.80% during the Purchase Period and 1.00%
during the Payout Period on the average daily net asset value of VALIC Separate
Account A. The exact rate depends on the Variable Account Option selected. This
charge is guaranteed and cannot be increased by the Company. The mortality and
expense risk fee is to compensate the Company for assuming mortality and expense
risks under Portfolio Director. The mortality risk that the Company assumes is
the obligation to provide payments during the Payout Period for your life no
matter how long that might be. In addition, the Company assumes the obligation
to pay during the Purchase Period an interest guaranteed death benefit. For more
information about the interest guaranteed death benefit see the "Death Benefit"
section of this prospectus. The expense risk is our obligation to cover the cost
of issuing and administering Portfolio Director T, no matter how large the cost
may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing (including but not limited to
enrollment, participant communication and education).
 
For more information about the mortality and expense risk fee, and
administration and distribution fee see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGES
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to its investment adviser. These
charges and other Fund charges and expenses are fully described in the
prospectuses for the Funds. These charges indirectly cost you because they lower
your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.
 
                                                                              19

- --------------------------------------------------------------------------------
 
REDUCTION OR WAIVER OF ACCOUNT MAINTENANCE FEE, SURRENDER, MORTALITY AND EXPENSE
RISK FEE OR ADMINISTRATION AND DISTRIBUTION FEE CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender charges, mortality and expense risk fee or administration and
distribution fee for Portfolio Director T may be reduced or waived. We may
reduce or waive these fees and charges if we determine that your retirement
program will allow us to reduce or eliminate administrative or sales expenses
that we usually incur for retirement programs. There are a number of factors we
will review in determining whether your retirement program will allow us to
reduce or eliminate these administrative or sales expenses:
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review to following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
We review the following additional factors to determine whether we can reduce or
waive the mortality and expense fee or administration and distribution fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
We will only do this if permitted by this Contract and by VALIC guidelines in
effect at the time. In no event will the reduction or waiver of fees and charges
be permitted where the reduction or waiver will unfairly discriminate against
any person.
 
SEPARATE ACCOUNT EXPENSE REIMBURSEMENT
 
   
Some of the Mutual Funds or their affiliates may have an agreement with the
Company to pay the Company for certain administrative and shareholder services
it provides to the underlying Fund. The Company will reduce its charges to the
Division investing in that Fund by the full amount of any of these payments it
receives. In addition, the Company currently reimburses certain Divisions a
portion of the Company's administration and distribution fee. Such reimbursement
arrangements are voluntary. See the Fee Table in this prospectus for an
identification of those Funds for which a reimbursement applies.

PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
(1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
   
With a Variable Payout, you may select from your existing Variable Account
Options. Your payments will vary accordingly. This is due to the varying
investment results that will be experienced by each of the Variable Account
Options you selected. The Payout Unit Value is calculated just like the Purchase
Unit Value for each Variable Account Option except that the Payout Unit Value
includes a factor for the Assumed Investment Rate you select. For additional
information on how Payout Payments and Payout Unit Values are calculated, see
the Statement of Additional Information.
    
 
   
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the Variable Account Option is lower than your
Assumed Investment Rate, your next payment will be less than your first payment.
    
 
COMBINATION FIXED AND VARIABLE
PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
   
Up to seven Variable Account Options may be chosen, or up to six Variable
Account Options if the Fixed Payout is chosen.
    
 
PAYOUT DATE
The Payout Date is the date elected by you on which your payout (annuity)
payments will start. The date elected must be the first of any month provided 30
days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              21
<PAGE>   479
 
- --------------------------------------------------------------------------------
 
    - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
      lifetime. Upon your death, your beneficiary will receive a lump sum
      payment equal to the remaining Annuity Value.
 
    - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
      lifetime of you and your beneficiary. Upon the death of one, payments
      continue during the lifetime of the survivor. This option is designed
      primarily for couples who require maximum possible variable payouts during
      their joint lives and are not concerned with providing for beneficiaries
      at death of the last survivor. For example, it would be possible under
      this option for the Joint Annuitants to receive only one payment if both
      Annuitants died prior to the date of the second payment, or for the Joint
      Annuitants to receive only one payment and the surviving Annuitant to
      receive only one payment if one Annuitant died prior to the date of the
      second payment and the surviving Annuitant dies prior to the date of the
      third payment.
 
    - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
      number of years between five and thirty. Upon your death, payments will
      continue to your beneficiary until the designated period is completed.
 
   
ENHANCEMENTS TO PAYOUT OPTIONS
    
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. The Joint and Survivor
Life Option may be available with a one to twenty year guaranteed period option.
Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
   
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
    
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option, and
 
  - The payments will be guaranteed for a 10 year period, and
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis,
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
   
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or plan.
    
 
For more information about
PAYOUT OPTIONS OR
ENHANCEMENTS
of those Payout Options
available under the Contract,
see the "Statement of
Additional Information".

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.
 
AMOUNT THAT MAY BE SURRENDERED
The amount that may be surrendered at any time can be determined as follows:
 
<TABLE>
<S>                    <C>               <C>
                                               Your
                                              Account
       Allowed                               Value(1)
      Surrender           = (EQUALS)         - (MINUS)
        Value                             Any Applicable
                                             Surrender
                                              Charge
</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See "Offering, Purchase and Redemption
of Fund Shares" in the Series Company Statement of Additional Information. See
your current Fund(s)' prospectuses for a discussion of the reasons why the
redemption of shares may be suspended or postponed.
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
   
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
    
 
   
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
    
 
PARTIAL SURRENDERS
   
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Options first unless otherwise specified by you.
    
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director T. There will be no surrender charge for withdrawals using this method,
which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
revoked, a systematic withdrawal may not be elected again. No more than one
systematic withdrawal election may be in effect at any one time. We reserve the
right to discontinue any or all systematic withdrawals or to change its terms,
at any time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW. There will be no surrender charge on
a minimum distribution required by federal tax law (known as No Charge Minimum
Distribution), if the withdrawal:

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
   
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director T. These other contracts are listed below. We
will allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director T. This exchange privilege will be available
only to other contracts purchased through your employer-sponsored retirement
plan and for which we have not yet started making payments under a Payout
Option. If you elect to exercise one of these exchange offers, you should
contact any of our Regional Offices at the addresses shown in the back of this
prospectus. An exchange may require the issuance of a Contract or may be subject
to any other requirements that the Company may impose.
    
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
   
  - Exchanges from Portfolio Director T to contract forms other than Portfolio
    Director 2 and Portfolio Director Plus are not permitted.
    
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director T. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director T. For example, you
will be subject to the rules concerning transfers among investment options as
stated in the Transfers Between Investment Options section in this prospectus.
We may, at our option, waive any transfer restrictions for a stated period of
time. If we waive these transfer restrictions, you will be allowed to exchange
to any investment option available in Portfolio Director T.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director T.
 
SURRENDER CHARGES
 
We will generally not impose nor waive existing surrender charges as a result of
your electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director T will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director T, the
contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director T will be the same date as the other contract, but no
earlier than January 1, 1982. (The effect of this is to potentially shorten the
charge period for Purchase Payments subsequently made to Portfolio Director T.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director T for purposes of calculating the surrender charge. The effective dates
of these Purchase Payments will also be retained for surrender charge purposes.
 
The Portfolio Director T surrender charge is calculated assuming the most recent
Purchase Payments are removed first. This policy may cause exchanged funds to be
accessible only after charges are imposed.

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director T will pay death benefits during either the Purchase Period
or the Payout Period. How these death benefits will be paid are discussed below.
The death benefit provisions in Portfolio Director T may vary from state to
state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
- - In a lump sum; or
 
- - In the form of an annuity under any of the Payout Options stated in the Payout
  Period section of this prospectus subject to the restrictions of that Payout
  Option.
 
   
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
    
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
- - In full within 5 years after the Annuitant's death; or
 
- - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
   
  - An annuity for a designated period not exceeding the Beneficiary's life
    expectancy.
    
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director T.
 
SPECIAL INFORMATION FOR INDIVIDUAL NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the
 
Annuitant's death. However, the Contract will be transferred to the Contingent
Owner, if any, or to the Contract Owner's estate. Such transfers will be
considered a taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:
Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Fixed Account Option on date
  proof of death Is received by VALIC
  OR
  100% of Purchase Payments placed
  in Fixed Account Option
- - (minus)
  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
</TABLE>
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Variable Account Option on date
  proof of death is received by VALIC
  OR
  100% of Purchase Payments placed in
  Variable Account Options
- - (minus)
  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option
+ (plus)
  Interest at an annual rate of 3%
</TABLE>
 
Step 3: Add step 1 + 2 = Death Benefit
 
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
BENEFICIARY -- the person
designated to receive Payout
Payments upon the death of
an Annuitant.
 
ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid.
 
   
CONTRACT OWNER -- either
your employer or organization
in the case of a group
contract or the Annuitant in
the case of an individual
contract. If the contract is an
individual non-qualified type,
this is generally the Annuitant
but is not required to be. Also,
a Contingent Contract Owner
may be designated.
    
 
FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options. Currently,
the Fixed Account Options in
Portfolio Director T are Fixed
Account Plus and Short-Term
Fixed Account. Each option
of this type is guaranteed to
earn at least a minimum rate
of interest.
 
   
VARIABLE ACCOUNT
    
OPTIONS -- investment
options that correspond to
VALIC Separate Account A
Divisions offered by Portfolio
Director T. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.
 
                                                                              27
<PAGE>   485
 
- --------------------------------------------------------------------------------
 
STANDARD DEATH BENEFIT
 
The standard death benefit is payable if death occurs on or after age 70.
 
The Standard Death Benefit will be the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Your Account Value on the Date Proof of Death is
  Received by VALIC
  OR
  100% of Purchase Payments (to Fixed
  and/or Variable Account Options)
- -- (MINUS)
  Amount of all Prior Withdrawals, Charges
  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director T are described in the "Payout Period" section
of this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed
       period option chosen by the deceased Participant; or
 
     - Receive the present value of any remaining payments applied under the
       Payment for a Designated Period Option for a period equal to or shorter
       than the period remaining. Spouse beneficiaries may be entitled to more
       favorable treatment under federal tax law.

HOW TO REVIEW INVESTMENT PERFORMANCE OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
   
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts or to the general public
before Portfolio Director T was first available to you. We may therefore,
advertise investment performance since the inception of the underlying Funds. In
each case, we will use the charges and fees imposed by Portfolio Director T in
calculating the Division's investment performance for earlier time frames.
    
 
TYPES OF INVESTMENT PERFORMANCE INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
Standard Average Annual Total Return shows the average percentage change in the
value of an investment in the Division from the beginning to the end of a given
historical period. The results shown are after all charges and fees have been
applied against the Division. This will include
   
account maintenance fees and surrender charges that would have been deducted if
you surrendered Portfolio Director T at the end of each period shown. Premium
taxes are not deducted. This information is calculated for each Division based
on how an initial assumed payment of $1,000 performed at the end of 1, 3, 5 and
10 year periods. If Standard Average Annual Return for a Division is not
available for a stated period, we may show the Standard Average Annual Return
since Division inception.
    
 
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
 
NONSTANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance information of an underlying Fund
reduced by Account fees for a period prior to the inception of the corresponding
Division is nonstandard performance information regardless of whether all
account fees and charges are deducted.
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director T will stay
in the Division beyond the time that a surrender charge would apply. It may be
calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    
 
   
DIVISIONS -- subaccounts of
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director T. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
    
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director T.
 
For more information on how
TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.
 
                                                                              29
<PAGE>   487
 
- --------------------------------------------------------------------------------
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the Division's Annual
Change in Purchase Unit Value.
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director T charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC MONEY MARKET DIVISION
 
We may advertise the AGSPC Money Market Division's Current Yield and Effective
Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market Division over a given 7-day period. The Current Yield does not take
into account surrender charges, account maintenance fees or premium taxes. The
income produced over a 7 day period is then "annualized." This means we are
assuming the amount of income produced during the 7-day period will continue to
be produced each week for an entire year. The annualized amount is shown as a
percentage of the investment. The annualized 7-day Current Yield for the last 7
days ended December 31, 1998 was 3.84%.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause the Effective Yield to be higher than the Current
Yield. The annualized 7-day Effective Yield for the last 7 days ended December
31, 1998 was 3.91%.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET DIVISION
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market Division. The yield for each of these Divisions will be
determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION:
 
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
   
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate Account A
Division is printed in the six tables below.
    
 
The information presented does not reflect the advantage under Portfolio
Director T of deferring federal income tax on increases in Account Value due to
earnings attributable to Purchase Payments (see "Federal Tax Matters" in the
prospectus and in the Statement of Additional Information.) The information
presented also does not reflect the advantage under Qualified Contracts of
deferring federal income tax on Purchase Payments.
 
The performance information presented in the following tables reflects the
performance of the underlying Fund after deduction of a mortality and expense
risk fee and administration and distribution fee at an aggregate annualized rate
of 0.80% during the Purchase Period on the daily net asset value of VALIC
Separate Account A. The exact rate depends upon the Variable Account Option
selected.
 
The performance results shown in the following tables are not an estimate or
guarantee of future investment performance, and do not represent the actual
experience of amounts invested by a particular Participant.

  * The performance figures in the Table reflect the investment performance for
    the Divisions for the stated periods and should not be used to infer that
    future performance will be the same. The Standard Average Annual Total
    Return figures are based on the average percentage change in the value of an

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director T
was issued in connection with a nonqualified and unfunded deferred compensation
plan.
 
DETERMINATION OF FUND SHARES ATTRIBUTABLE TO YOUR ACCOUNT
 
DURING PURCHASE PERIOD
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
DURING PAYOUT PERIOD OR AFTER A DEATH BENEFIT HAS BEEN PAID
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director T
may have a number of shareholders including VALIC Separate Account A, VALIC
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies and public shareholders.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
   
VALIC Separate Account A will vote the shares of the Funds it holds based on,
and in the same proportion as, the voting instructions received from
participants in VALIC Separate Account A.
    
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.
 
VALIC SEPARATE
ACCOUNT A -- a segregated
asset account established by
VALIC under the Texas

TYPE OF PLANS
 
   
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program or 408(b) IRA, as a Section 408(b)
Individual Retirement Annuity ("IRA"), or is instead a nonqualified Contract.
Portfolio Director T is used under the following types of retirement
arrangements:
    
 
  - Section 403(b) annuities for employees
     of public schools and
     Section 501(c)(3) tax-exempt
     organizations;
  - Section 401(a) and 403(a) qualified plans of for-profit employers and other
    employers (including self-employed individuals);
 
   
  - Section 408(b) IRAs;
    
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
   
  - Section 408(k) SEPs;
    
 
  - Section 408(p) SIMPLE retirement
     accounts.
 
   
The foregoing Contracts are "Qualified Contracts." Portfolio Director T may also
be available through a nondeductible Section 408A "Roth" individual retirement
annuity ("Roth IRA").
    
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
   
In addition, Portfolio Director T is also available through "Non-Qualified
Contracts" to the extent acquired by "Non-Natural Persons." Such Non-Qualified
Contracts generally include unfunded, nonqualified deferred compensation plans
of corporate employers, as well as individual annuity contracts issued to
individuals outside of the context of any formal employer or employee retirement
plan or arrangement. Non-Qualified Contracts generally may invest only in mutual
funds which are not available to the general public outside of annuity contracts
or life insurance contracts..
    
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director T can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Qualified Contracts receive deferral of tax on
the inside build-up of earnings on invested Purchase Payments, until a
distribution occurs. See the Statement of Additional Information for special
rules, including those applicable to taxable, non-natural owners of
Non-Qualified Contracts.
 
   
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
    
 
Distributions are taxed differently depending on the program through which
Portfolio Director T is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
   
Amounts subject to income tax may also incur excise tax or penalty taxes under
the circumstances described in the Statement of Additional Information.
Generally, they would
    
 
 36
<PAGE>   494
 
- --------------------------------------------------------------------------------
 
   
also be subject to some form of federal income tax withholding unless rolled
into another tax-deferred vehicle. Required withholding will vary according to
type of program, type of payment and your tax status. In addition, amounts
received under all Contracts may be subject to state income tax withholding
requirements.
    
 
   
It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if purchase payments under the contract are invested in
publicly available mutual funds. In a ruling published in 1981, the Internal
Revenue Service ("IRS") had taken the position that, where purchase payments
under a variable annuity contract are invested in publicly available mutual
funds, the contract owner should be treated as the owner of the mutual fund
shares, and deferred tax treatment under the contract should not be available.
In the opinion of VALIC and its tax counsel, the 1981 ruling has been superseded
by subsequent legislation (Code Section 817(h)) which specifically exempts these
Qualified Contracts, and the IRS has no viable legal basis or reason to apply
the theory of the 1981 ruling to these Qualified Contracts under current law.
Although VALIC can provide no assurance the IRS will not challenge the deferred
tax treatment of these Qualified Contracts under the theory of the 1981 ruling,
VALIC and its tax counsel believe that Contract owners would prevail, if such a
challenge were made.
    
 
   
It is also the opinion of VALIC and its tax counsel that for each other type of
Qualified Contract an independent exemption provides tax deferral regardless of
how ownership of the Mutual Fund shares might be computed for federal income tax
purposes.
    
 
   
Investment earnings on contributions to Non-Qualified Contracts which are not
owned by natural persons will be taxed currently to the owner and such contracts
will not be treated as annuities for federal income tax purposes.
    
 
EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director T Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
                        THE POWER OF TAX-DEFERRED GROWTH
                                  [BAR GRAPH]
 
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. The deduction of
fees and charges for both tax-deferred plans is reflected in the chart. Variable
options incur mortality and expense risk fee and administration and distribution
fee charges (0.80% during the purchase period and 1% during the payout period)
and may also incur account maintenance fees ($3.75 per quarter) and surrender
charges (5% of the lesser of all contributions received during the last 60
months or the amount withdrawn). The dotted lines represent the amounts
remaining after withdrawal and payment of taxes and any surrender charge. An
additional 10% tax penalty may apply to withdrawals before age 59 1/2. This
information is for illustrative purposes only and is not a guarantee of future
return.
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.
 
To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE
REDUCED BY THE IMPACT OF INCOME TAXES UPON WITHDRAWAL. The yield will vary
depending upon the timing of withdrawals. The previous chart represents (without
factoring in fees and charges) after-tax amounts that would be received.
 
                                                                              37
<PAGE>   495
 
- --------------------------------------------------------------------------------
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

</TABLE>
 
This chart assumes a 28% federal income tax rate. The $700 which is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800, while the full $2,500 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a tax-
qualified retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-qualified retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
   
YEAR 2000 RISKS
    
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
  - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
    Problem. This plan includes the five steps that we believe are essential to
    Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or
    replace systems that are not Year 2000 ready; (4) test systems to prove that
    they will work correctly into the year 2000; and (5) return the systems to
    operations. As of December 31, 1998, we have substantially completed all
    steps with respect to our critical systems.
    
 
   
  - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that
    must also be Year 2000 ready. Third parties are companies that provide
    certain services to VALIC. Third parties are different from internal systems
    in that VALIC has less, or no, control over their Year 2000 readiness. VALIC
    has developed a plan to review and try to lessen the Year 2000 risks of
    third parties. As of December 31, 1998, VALIC has substantially completed
    its review of third party Year 2000 risks. VALIC intends to test third party
    Year 2000 readiness throughout 1999.
    
 
   
  - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
    associated with the Year 2000 Problem. The contingency plans for third party
    relationships include the following activities: (1) evaluate the
    consequences of any failures associated with the Year 2000 Problem; (2)
    determine the chance of a Year 2000-related failure for systems that have a
    high chance of failing; (3) develop an action plan to complete contingency
    plans for those systems that rank high in both impact of failure and chance
    of failure; and (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.

(1) Bankers Trust Company (the "Sub-Adviser") is a wholly owned subsidiary of
    Bankers Trust Corporation. On November 30, 1998, Bankers Trust Corporation
    entered into an Agreement and Plan of Merger with Deutsche Bank AG under
    which Bankers Trust Corporation and all of its subsidiaries would merge with
    and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a major
    global banking institution that is engaged in a wide range of financial
    services, including retail and commercial banking, investment banking and
    insurance. The merger is contingent upon various regulatory approvals. On
    April 20, 1999, the AGSPC Fund's Board of Directors approved a new
    investment sub-advisory agreement with Bankers Trust Company, subject to
    shareholder approval. If the merger is approved and completed, Deutsche Bank
    AG, as the Sub-Adviser's new parent company, will control the operations of
    the Sub-Adviser. Bankers Trust believes that, under this new arrangement,
    the services provided to the Fund will be maintained at their current level.

SUMMARY -- (CONTINUED)
    
- --------------------------------------------------------------------------------
 
   
A detailed description of the investment objective of each Mutual Fund can be
found in the section of the prospectus entitled "Variable Account Options," and
also in the current prospectus for each Fund mentioned.
    
 
INTEREST GUARANTEED DEATH BENEFIT
Portfolio Director offers a death benefit with an interest guarantee when death
occurs prior to your reaching age 70.
 
This contract provision is not available in some states.
 
LOANS
Portfolio Director offers a tax-free loan provision for tax-qualified contracts
that gives you access to your money in either of the Fixed Account Options,
subject to a minimum loan amount of $1,000. The availability of loans is subject
to government regulations, as well as your employer's plan provisions.
 
Keep in mind that tax laws place restrictions on withdrawals (i.e. loans which
are not repaid) if made prior to age 59 1/2.
 
TRANSFERS
There is no charge to transfer the money in your account among Portfolio
Director's investment options. You may transfer your Account Values between
Variable Account Options at any time during the Purchase Period.
 
Your Account Value in the Short-Term Fixed Account must remain there for at
least 90 days before it can be transferred to other investment options. In Fixed
Account Plus, up to 20% of your Account Value may be transferred during each
contract year to other investment options.
 
Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among Variable Account Options once each contract
year.
 
Transfers can be made by calling VALIC's toll-free transfer service at
1-800-621-7792. For more information on account transfers, see the "Transfers
Between Investment Options" section in the prospectus.
 
FEES AND CHARGES
 
ACCOUNT MAINTENANCE FEE
If any of your account is invested in Variable Account Options, a quarterly
account maintenance fee of $3.75 is charged to your account. If you invest only
in Fixed Account Options during a calendar quarter no account maintenance fee is
assessed. Reductions in the account maintenance fee may be available if certain
conditions are met.
 
SURRENDER CHARGE
Under some circumstances a surrender charge is made to your account. These
situations are discussed in detail in the section of the prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed in two ways and you are charged whichever amount is less. The first
amount is simply 5% of whatever amount you have withdrawn. The second amount is
5% of the contributions you made to your account during the last 60 months.
Withdrawals are always subject to your plan provisions and federal tax
restrictions, which generally include a tax penalty on withdrawals made prior to
age 59 1/2.
 
PREMIUM TAX CHARGE
   
Premium taxes ranging from zero to 3 1/2% are currently imposed by certain
states and municipalities on Purchase Payments made under the contract.
    
 
SEPARATE ACCOUNT CHARGES
Depending on the Variable Account Option you choose, you may incur a mortality
and expense risk fee and an administration and distribution fee computed at an
annualized rate of 1.00% to 1.25% on the average daily net asset value of VALIC
Separate Account A. Reductions in the mortality and expense risk fee and
administration and distribution fee may be available for plan types meeting
certain criteria.
 
FUND ANNUAL EXPENSE CHARGE
A daily charge based on a percentage of each Fund's average daily net asset
value is payable by each Fund to its investment adviser. In addition to the
management fees, each Fund incurs other operating expenses which may vary.
 
Since some of these fees may not apply to your contract, consult your VALIC
Retirement Plan Specialist to see how these provisions apply to you.
 
Separate Account
Expense Reimbursement
   
The Company will reimburse to certain Divisions any fees it receives from the
Mutual Fund or its affiliate or distributor for providing the Mutual Fund
administrative and shareholder services. In addition, the Company currently
reimburses certain Divisions a portion of the Company's administration and
distribution fee for providing Variable Account Options. Such reimbursement
arrangements are voluntary. For more information as to which Variable Account
Options have a Separate Account Expense Reimbursement see the Fee Table.
    
 
PAYOUT OPTIONS
When you withdraw your money, you can select from several payout options: a
lifetime annuity (which guarantees payment for as long as you live), periodic
withdrawals and systematic withdrawals. More information on payout options can
be found in the "Payout Period" section of the prospectus.
 
FEDERAL TAX INFORMATION
Although deferred annuity contracts such as Portfolio Director can be purchased
with after-tax dollars, they are primarily used in connection with retirement
programs which receive favorable tax treatment under federal law.
 
PURCHASE REQUIREMENTS
Purchase Payments may be made at any time and in any amount, subject to plan
limitations.
 
To learn more about the
INTEREST GUARANTEED DEATH
BENEFIT, refer to the section
in the prospectus entitled
"Death Benefits."
 
More information on FEES
may be found in the
prospectus under the
headings "FEES AND CHARGES"
AND "FEE TABLE."
 
For a more detailed
discussion of these income
tax provisions, see the
"FEDERAL TAX MATTERS"
section of the prospectus and
of the Statement of Additional
Information.
 
For more information on
PURCHASE PAYMENTS, refer
to the "Purchase Period"
section of the prospectus.

(2) Effective October 1, 1991, the Fund underlying this Division changed its
    name from the Capital Accumulation Fund to the MidCap Index Fund and amended
    its investment objective, investment program and investment restrictions
    accordingly. Historical purchase unit values prior to October 1, 1991
    reflect investment experience before these changes.
    
 
   
(3) Effective with the merger of Quality Growth Fund into Stock Index Fund on
    May 1, 1992, Quality Growth Division 9 was merged into Stock Index Division
    10. The merger of Divisions was accomplished by an exchange of units of
    Quality Growth Division 9 for units of Stock Index Division 10 of equivalent

of Additional Information, which is available upon request. Purchase units shown
are for a Purchase Unit outstanding throughout the year under a representative
Contract of the type invested in each column shown. The unit value of each
Division of VALIC Separate Account A will not be the same on any given day as
the net asset value per share of the underlying Fund of the Series Company and
the other mutual fund portfolios described in this prospectus in which that
Division invests. This is because each unit value consists of the underlying
share's net asset value minus the charges to VALIC Separate Account A. In
addition, dividends declared by the underlying Fund are reinvested by the
Division in additional shares. These distributions have the effect of reducing
the value of each share of the Fund and increasing the number of Fund shares
outstanding. However, the total cash value in VALIC Separate Account A does not
change as a result of such distributions.

ABOUT PORTFOLIO DIRECTOR
 
Portfolio Director was developed to help you save money for your retirement. It
offers you a combination of fixed and variable investment options that you can
invest in to help you reach your retirement savings goals. Your contributions to
Portfolio Director can come from different sources, like payroll deductions or
money transfers. Your retirement savings process with Portfolio Director will
involve two stages: the Purchase Period; and the Payout Period. The first is
when you make contributions into Portfolio Director called "Purchase Payments."
The second, is when you receive your retirement payouts. For more information,
see "Purchase Period" and the "Payout Period" in this prospectus.
 
You may choose, depending upon your retirement savings goals, your personal risk
tolerances, and your retirement plan, to invest in the Fixed Account Options
and/or the Variable Account Options described in this prospectus. When you
decide to retire, or otherwise withdraw your money, you can select from a wide
array of payout options including both fixed and variable payments. In addition,
this prospectus will describe for you all fees and charges that may apply to
your participation in Portfolio Director.

ABOUT VALIC SEPARATE ACCOUNT A
 
When you direct money to Portfolio Director's Variable Account Options, you will
be sending that money through VALIC's Separate Account A. You do not invest
directly in the Mutual Funds made available in Portfolio Director. VALIC's
Separate Account A invests in the Mutual Funds on behalf of your account.
VALIC Separate Account A is made up of what we call "Divisions." Sixteen
Divisions are available and represent the Variable Account Options in Portfolio
Director. Each of these Divisions invests in a different Mutual Fund made
available through Portfolio Director. For example, Division Ten represents and
invests in the AGSPC Stock Index Fund. The earnings (or losses) of each Division
are credited to (or charged against) the assets of that Division, and do not
affect the performance of the other Divisions of VALIC Separate Account A.
 
   
VALIC established Separate Account A on July 25, 1979 under Texas insurance law
to allow you to be able to invest in a number of Variable Account Options
available in Portfolio Director. VALIC Separate Account A is registered with the
Securities and Exchange Commission (SEC) as a unit investment trust under the
Investment Company Act of 1940 ("Act"). Units of interest in VALIC Separate
Account A are registered as securities under the Securities Act of 1933.
    
 
VALIC Separate Account A is administered and accounted for as part of VALIC's
business operations. However, the income, capital gains or capital losses,
whether or not realized of each Division of VALIC Separate Account A are
credited to or charged against the assets held in that Division without regard
to the income, capital gains or capital losses of any other Division or arising
out of any other business the Company may conduct. In accordance with the terms
of Portfolio Director, VALIC Separate Account A may not be charged with the
liabilities of any other VALIC operation. As stated in Portfolio Director, the
Texas Insurance Code requires that the assets of VALIC Separate Account A
attributable to Portfolio Director be held exclusively for the benefit of the
contract owner, participants, annuitants, and beneficiaries of Portfolio
Director. When we discuss performance information in this prospectus, we mean
the performance of a VALIC Separate Account A Division.
 
UNITS OF INTERESTS
 
Your investment in a Division of VALIC Separate Account A is represented by
units of interest issued by VALIC Separate Account A. On a daily basis, the
units of interest issued by VALIC Separate Account A are revalued to reflect
that day's performance of the underlying mutual fund minus any applicable fees
and charges to VALIC Separate Account A.

VARIABLE ACCOUNT OPTIONS
- --------------------------------------------------------------------------------
 
   
Portfolio Director enables you to participate in Divisions that represent
sixteen Variable Account Options. These Divisions comprise all of the Variable
Account Options that are made available to you through VALIC Separate Account A.
According to your retirement program, you may not be able to invest in all
sixteen Variable Account Options described in this prospectus. See "About VALIC
Separate Account A" in this prospectus.
    
 
Each individual Division represents and invests, through VALIC's Separate
Account A, in specific mutual funds. These mutual funds serve as the investment
vehicles for Portfolio Director and include:
 
- - American General Series Portfolio
   
  Company (AGSPC) -- offers 13 funds, for which VALIC serves as investment
  adviser, for 2 of such funds, T. Rowe Price & Associates, Inc. serves as
  investment sub-adviser and for 3 of such funds, Bankers Trust Company serves
  as investment sub-adviser.
    
 
- - Dreyfus Variable Investment Fund -- offers 1 fund, for which The Dreyfus
  Corporation serves as investment adviser.
 
- - Templeton Variable Products Series -- offers 2 funds, for which Templeton
  Investment Counsel, Inc. serves as investment adviser.
 
Each of these Funds (except for AGSPC's International Government Bond Fund which
is a non-diversified fund) is registered as a diversified open-end, management
investment company and is regulated under the Investment Company Act of 1940.
For complete information about each of these Funds, including charges and
expenses, you should refer to the prospectus for that Fund. Additional copies
are available from VALIC or you may contact your VALIC Regional Office at the
addresses shown in the back of this prospectus.
 
Shares of the Dreyfus Small Cap Portfolio, the Templeton Asset Allocation Fund,
and the Templeton International Fund are also sold to separate accounts of other
insurance companies that may or may not be affiliated with us. This is known as
"shared funding." These funds may also be sold to separate accounts that act as
the underlying investments for both variable annuity contracts and variable life
insurance policies. This is known as "mixed funding." There are certain risks
associated with mixed and shared funding. These risks are discussed in each
Fund's prospectus.
 
SUMMARY OF FUNDS
 
   
A brief summary of the investment objectives of each mutual fund is shown below.
In addition to the investment objectives, the Account Value of an assumed
$10,000 investment in each of the Divisions is shown in both table and graph
form as well as the Standard Average Annual Total Return for a 1, 3, 5 and 10
year period, if available. If Standard Average Annual Return for a Division is
not available for a stated period, we may show the Standard Average Annual
Return since Division inception. The performance information in the tables and
graphs will reflect a deduction for separate account fees (mortality and expense
risk fees plus administration and distribution fees minus any applicable
reimbursements) and underlying fund charges. This will not reflect any deduction
for account maintenance fees, surrender charges and premium taxes. These charges
would further reduce your return. The Account Values shown in the graphs reflect
Separate Account performance based on the performance of the underlying Fund for
the last 10 fiscal years or, since inception of the underlying Fund if for less
than 10 years. The returns shown in the tables reflect for the AGSPC Funds
actual historical performance of the related Separate Account Divisions. The
returns shown in the tables for the other Funds (Divisions 18-20) reflect actual
historical performance of the related Separate Account Divisions since inception
of each Division (July 11, 1994) and hypothetical performance is based on the
actual performance for periods prior to July 11, 1994. Hypothetical performance
is based on the actual performance of the underlying Fund reduced by Separate
Account fees that would have been incurred during the hypothetical period.
Investment return and principal value will fluctuate with market conditions, and
for foreign investments, currencies and the economic and political climates of
the countries where investments are made. Past performance cannot predict or
guarantee future results.
    
 
   
The Standard Average Annual Total Return figures show the average percentage
change in the value of an investment in a Division from the beginning to the end
of the historical periods shown below. The results shown are after all charges
and fees have been applied against the Division. This will include account
maintenance fees and surrender charges that would have been deducted if you
surrendered Portfolio Director at the end of the specified period. Premium taxes
are not deducted. This information is calculated for each Division based on how
an initial investment of $1,000 performed at the end of the specified periods
shown.
    
 
   
For more information about how these returns were calculated including a
statement of the charges reflected and tables showing historical performance
information, see "How to Review Investment Performance of Separate Account
Divisions" in this prospectus.

PURCHASE PERIOD
- --------------------------------------------------------------------------------
 
The Purchase Period begins when your first Purchase Payment is made and
continues until you begin your Payout Period. The Purchase Period can also end
when a Portfolio Director account is surrendered before the Payout Period. The
amount, number, and frequency of your Purchase Payments is determined by the
retirement plan for which Portfolio Director was purchased.
 
PURCHASE PAYMENTS
You may establish an account only through a VALIC representative. Initial
Purchase Payments must be received by VALIC either with, or after, a completed
application. Your employer is usually responsible for remitting Purchase
Payments to us. The employer is responsible for furnishing instructions to us (a
premium flow report) as to the amount being applied to your account. Purchase
Payments can also be made by you for IRAs and certain non-qualified contracts
("individual contracts.")
 
Minimum initial and subsequent Purchase Payments are as follows:
 
<TABLE>
<CAPTION>
                         Initial    Subsequent
     Contract Type       Payment     Payment
     -------------       -------    ----------
<S>                      <C>        <C>
Periodic Payment         $   30        $ 30
Single Payment           $1,000         -0-
</TABLE>
 
   
Periodic Payment minimums apply to each Periodic Payment made. The Single
Payment minimum applies to each of your accounts.
    
 
Purchase Payments are received in VALIC's Home Office. When an initial Purchase
Payment is accompanied by an application, within 2 business days we will:
 
- - Accept the Application -- and issue a contract. We will also establish your
  account and apply your Purchase Payment by crediting the amount to the Fixed
  Account Option or Variable Account Option selected;
 
- - Reject the Application -- and return the Purchase Payment; or
 
   
- - Request Additional Information -- to correct or complete the application. In
  the case of an individual variable annuity contract, we will return the
  Purchase Payments within 5 business days if the requested information is not
  provided, unless you otherwise so specify.
    
 
If we receive Purchase Payments from your employer before we receive your
completed application or enrollment form, we will not be able to establish a
permanent account for you. Under these circumstances, we will take one of the
following actions:
 
  Return Purchase Payments. If we do not have your name, address or social
  security number, we will return the Purchase Payment to your employer unless
  this information is immediately provided to us.
 
  Employer-Directed Account. If we have your name, address and social security
  number and we have an Employer-Directed Account Agreement from your employer,
  generally we will deposit your Purchase Payment in an "Employer-Directed"
  account invested in the AGSPC Money Market Division Option. You may not
  transfer these amounts until VALIC has received a completed application or
  enrollment form.
 
  Starter Account. If we have your name, address and social security number, but
  we do not have an Employer-Directed Account Agreement from your employer, we
  will deposit your Purchase Payment in a "starter" account invested in the
  AGSPC Money Market Division. We will send you follow-up letters requesting the
  information necessary to complete the application, including your allocation
  instructions. Unless a completed application or enrollment form is received by
  us within 105 days of establishment of your starter account, the account
  balance, including earnings, will be returned to your employer. We are not
  responsible for any adverse tax consequences to you that may result from the
  return of your employer's contributions.
 
PURCHASE UNITS
A Purchase Unit is a unit of interest owned by you in your Variable Account
Option. Purchase Units apply only to the Variable Account Options selected for
your account. Purchase Unit values are calculated at the close of regular
trading of the New York Stock Exchange (the "Exchange"), currently 4:00 p.m. New
York time (see Calculation of Purchase Unit Value below for more information.)
Purchase Units will be credited the same business day if Purchase Payments are
received by our Home Office before the close of the Exchange. If not, they will
be calculated and credited the next business day. Purchase Unit values will vary
depending on the net investment results of each of the Variable Account Options.
This means the value of your Variable Account Option will fluctuate.
 
CALCULATION OF PURCHASE UNIT VALUE
The Purchase Unit value for a Division is calculated as shown below:
Step 1: Calculate the gross investment rate:
 
  Gross Investment Rate
= (EQUALS)
  The Division's investment income
  and capital gains and losses
  (whether realized or unrealized) on
  that day from the assets
  attributable to the Division.
/ (DIVIDED BY)
  The value of the Division for
  the immediately preceding day on
  which the values are calculated.
 
   
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director 2.
    
 
   
PURCHASE UNIT -- a
measuring unit used to
calculate your Account Value
during the Purchase Period.
The value of a Purchase Unit
will vary with the investment
experience of the Separate
Account Division you have
selected.
    

For more information as to
how PURCHASE UNIT VALUES
are calculated, see the
Statement of Additional
Information.
 
                                                                              19
<PAGE>   526
 
- --------------------------------------------------------------------------------
 
   
We calculate the gross investment rate as of 4:00 p.m. New York time on each
business day when the Exchange is open.
    
Step 2: Calculate net investment rate for any day as follows:
 
  Net Investment Rate
= (EQUALS)
  Gross Investment Rate
  (calculated in Step 1)
- - (MINUS)
  Separate Account charges and any
  income tax charges.
 
Step 3: Determine Purchase Unit Value for that day.
 
  Purchase Unit Value for that day.
= (EQUALS)
  Purchase Unit Value for immediate
  preceding day.
X (MULTIPLIED BY)
  Net Investment Rate (as calculated
  in Step 2) plus 1.00.
 
CHOOSING INVESTMENT OPTIONS
   
There are 18 investment options offered in Portfolio Director. This includes 2
Fixed Account Options and 16 Variable Account Options. Unless provided
otherwise, you may select and combine up to 7 of the 18 options. The Funds that
underlie the Variable Account Options are registered as investment companies
under and are subject to regulation of the Act. The Fixed Account Options are
not subject to regulation under the Act and are not required to be registered
under the Securities Act of 1933. As a result, the SEC has not reviewed data in
this prospectus that relates to the Fixed Account Options. However, federal
securities law does require such data to be accurate and complete.
    
 
FIXED ACCOUNT OPTIONS
   
Each of the Fixed Account Options are part of the Company's general assets. You
may allocate all or a portion of your Purchase Payment to the Fixed Account
Options listed in "Summary" appearing in this prospectus. Purchase Payments you
allocate to these Fixed Account Options are guaranteed to earn at least a
minimum rate of interest. Interest is paid on each of the Fixed Account Options
at declared rates, which may be different for each option. We bear the entire
investment risk for the Fixed Account Option. All Purchase Payments and interest
earned on such amounts in your Fixed Account Option will be paid regardless of
the investment results experienced by the Company's general assets.
    
Here is how you may calculate the value of your Fixed Account Option during the
Purchase Period:
 
  Value of Your Fixed
  Account Options
= (EQUALS)
  All Purchase Payments made to the
  Fixed Account Options
+ (PLUS)
  Amounts transferred from Variable
  Account Options to the Fixed
  Account Options
+ (PLUS)
  All interest earned
- - (MINUS)
  Amounts transferred or withdrawn
  from Fixed Account Options
  (including applicable fees and
  charges)
 
VARIABLE ACCOUNT OPTIONS
   
You may allocate all or a portion of your Purchase Payments to the Variable
Account Options listed in this prospectus as permitted by your retirement
program. A complete discussion of each of the Variable Account Options may be
found in the "Variable Account Options" section in this prospectus. Based upon a
Variable Account Option's Purchase Unit Value your account will be credited with
the applicable number of Purchase Units. The Purchase Unit Value of each
Variable Account Option will change daily depending upon the investment
performance of the underlying fund (which may be positive or negative) and the
deduction of VALIC Separate Account A charges. See the "Fees and Charges"
section in this prospectus. Because Purchase Unit Values change daily, the
number of Purchase Units your account will be credited with for subsequent
Purchase Payments will vary. Each Variable Account Option bears its own
investment risk. Therefore, the value of your account may be worth more or less
at retirement or withdrawal.
    
Here is how to calculate the value of each Variable Account Option in your
account during the Purchase Period:
 
  Value of Your Variable Account Option
= (EQUALS)
  Total Number of Purchase Units
X (MULTIPLIED BY)
  Current Purchase Unit Value
 
STOPPING PURCHASE PAYMENTS
   
Purchase Payments may be stopped at any time. Purchase Payments may be resumed
at any time before your Portfolio Director account has been surrendered. The
value of the Purchase Units will continue to vary. Your Account Value will
continue to be subject to charges.
    
 
   
If your Account Value falls below $300, and you do not make any Purchase
Payments for two years from the date we established your account, we may close
the account and pay the Account Value (less any surrender charge) to you. Any
such account closure will be subject to applicable distribution restrictions
under the Contract and/or under your employer's plan.

COMMUNICATING TRANSFER OR
REALLOCATION INSTRUCTIONS
A written instruction to transfer or reallocate all or part of your Account
Value between the various investment options in Portfolio Director, should be
sent to VALIC's Home Office.
 
Instructions for transfers or reallocations may be made by calling
1-800-621-7792. Telephone transfers will be allowed unless we have been notified
not to accept such telephone instructions. In this event, we must receive
written instructions, in order to permit future telephone transfers to be made.
Before a transfer will be made by telephone, you must give us the requested
identifying information concerning your account(s).
 
Unless we have been instructed not to accept requests for telephone transfers,
anyone may effect a telephone transfer if they furnish the requested
information. You will bear any loss resulting from such instructions, whether
the caller was specifically authorized by you or not.
 
No one that we employ or that represents VALIC may give telephone instructions
on your behalf without VALIC's prior written permission. (This does not apply to
a contract with the immediate family of an employee or representative of VALIC).
 
We will send you a confirmation of the completed transfer within 5 days from the
date of your instruction. When you receive your confirmation, it is your duty to
verify the information shown, and advise us of any errors within one business
day.
 
You will bear the risk of loss arising from instructions received by telephone.
We are not responsible for the authenticity of such instructions. Any telephone
instructions which we reasonably believe to be genuine will be your
responsibility. This includes losses from errors in communication. Telephone
transfer instruction may not be made during the Payout Period. We reserve the
right to stop telephone transfers at any time.
 
EFFECTIVE DATE OF TRANSFER
The effective date of a transfer will be:
 
   
- - The date of receipt, if received in our Home Office before the close of
  regular trading of the Exchange on a day values are calculated; (Normally,
  this will be 4:00 P.M. New York time); otherwise
    
 
- - The next date values are calculated.

FEES AND CHARGES
- --------------------------------------------------------------------------------
 
By investing in Portfolio Director, you may be subject to six basic types of
fees and charges:
 
- - Account Maintenance Fee
- - Surrender Charge
- - Premium Tax Charge
- - Separate Account Charges
- - Fund Annual Expense Charge
- - Other Tax Charges
 
These fees and charges are explained below. For additional information about
these fees and charges, see the Fee Table in this prospectus.
 
ACCOUNT MAINTENANCE FEE
 
An account maintenance fee of $3.75 will be deducted on the last day of each
calendar quarter if any of your money is invested in the Variable Account
Options. We will sell Purchase Units from your Account to pay the account
maintenance fee. If you invest only in Fixed Account Options during a calendar
quarter, this fee will not apply. If all your money in a Variable Account Option
is withdrawn, or transferred to a Fixed Account Option, the fee will be deducted
at that time. The fee will be assessed equally among the Variable Account
Options that make up your Account Value.
 
The account maintenance fee is to reimburse the Company for our administrative
expenses for providing Variable Account Options. This includes the expense for
establishing and maintaining the record keeping for the Variable Account
Options. We do not expect that the amount of fees we receive will be greater
than our expenses.
 
The amount of the account maintenance fee may be reduced or waived if Portfolio
Director is issued to certain types of plans which are expected to result in
lower costs to VALIC. To learn more about how we determine if account
maintenance fees may be reduced or waived, see the "Reduction or Waiver of
Account Maintenance Fee, Surrender, Mortality and Expense Risk Fee or
Administration and Distribution Fee Charges" section in this prospectus. If you
have two or more accounts established under the same group contract, we may
agree to deduct an account maintenance fee from only one account.
 
SURRENDER CHARGE
 
   
When you withdraw money from your account, you may be subject to a surrender
charge that will be deducted from the amount withdrawn. For information about
your right to surrender, see "Surrender of Account Value" in this prospectus.
    
 
It is assumed that the most recent Purchase Payments are withdrawn first. No
surrender charge will be applied unless an amount is actually withdrawn. We
consider all Purchase Payments to be withdrawn before earnings are withdrawn.
 
Amounts exchanged from other contracts issued by the Company may or may not be
subject to a surrender charge. After exchange, it is assumed that any new
Purchase Payments are withdrawn before the exchanged amount. For more
information, see "Exchange Privilege" in the Statement of Additional
Information.
 
AMOUNT OF SURRENDER CHARGE
 
A surrender charge may not be greater than:
 
- - Five percent (5%) of the amount of all Purchase Payments received during the
  past 60 months; or
 
- - Five percent (5%) of the amount withdrawn.
 
10% FREE WITHDRAWAL
 
In any Participant Year, up to 10% of the Account Value may be withdrawn without
a surrender charge. The surrender charge will apply to any amount withdrawn that
exceeds this 10% limit. The percentage withdrawn will be determined by dividing
the amount withdrawn by the Account Value just prior to the withdrawal. If more
than one withdrawal is made during a Participant Year, each percentage will be
added to determine at what point the 10% limit has been reached.
 
These 10% withdrawals without charge do not reduce Purchase Payments for the
purpose of computing the surrender charge. If a surrender charge is applied to
all or part of a Purchase Payment, no surrender charge will be applied to such
Purchase Payment (or portion thereof) again.
 
EXCEPTIONS TO SURRENDER CHARGE
 
No surrender charge will be applied:
 
- - To money applied to provide a Payout Option;
 
- - To death benefits;
 
- - If no Purchase Payments have been received during the 60 months prior to the
  date of surrender;
 
- - If your account has been in effect for 15 years or longer;
 
- - If your account has been in effect for 5 years or longer, and you have
  attained age 59 1/2;
 
- - To "No Charge Systematic Withdrawals";
 
- - Under certain contracts, to withdrawals under the No Charge Minimum
  Distribution provisions;
 
PARTICIPANT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract or
certificate.

- --------------------------------------------------------------------------------
 
- - If you have become totally and permanently disabled, defined as follows: You
  are unable, due to mental or physical impairment, to perform the material and
  substantial duties of any occupation for which you are suited by means of
  education, training or experience; the impairment must have been in existence
  for more than 180 days; the impairment must be expected to result in death or
  be long-standing and indefinite and proof of disability must be evidenced by a
  certified copy of a Social Security Administration determination or a doctor's
  verification; or
 
- - If you are at least 55 years old, are no longer employed by the employer that
  established the plan, and your account under the plan was established at least
  5 years prior to the date of surrender.
 
The surrender charge may be reduced or waived if Portfolio Director is issued to
certain types of plans which are expected to result in lower costs to VALIC. To
learn more about how we determine if a surrender charge may be reduced or
waived, see the "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
section in this prospectus.
 
PREMIUM TAX CHARGE
 
   
Taxes on Purchase Payments are imposed by some states, cities, and towns. The
rate will range from zero to 3 1/2%.
    
 
If the law of a state, city, or town requires premium taxes to be paid when
Purchase Payments are made, we will, of course, comply. Otherwise, such tax will
be deducted from the Payout Value when annuity payments are to begin.
 
If we deduct an amount for premium taxes, but later find the tax was not due, we
will:
 
- - Adjust the amount deducted in error to reflect investment experience from the
  date of the deduction to the date we determined the tax was not due; and
 
- - Apply the excess amount, as adjusted, to increase the number of Pay-in or
  Payout Units.
 
SEPARATE ACCOUNT CHARGES
 
There will be a mortality and expense risk fee and an administration and
distribution fee applied to VALIC Separate Account A. This is a daily charge at
an annualized rate of 1.00% to 1.25% on the average daily net asset value of
VALIC Separate Account A. The exact rate depends on the Variable Account Option
selected. This charge is guaranteed and cannot be increased by the Company. The
mortality and expense risk fee is to compensate the Company for assuming
mortality and expense risks under Portfolio Director. The mortality risk that
the Company assumes is the obligation to provide payments during the Payout
Period for your life no matter how long that might be. In addition, the Company
assumes the obligation to pay during the Purchase Period an interest guaranteed
death benefit. For more information about the interest guaranteed death benefit
see the "Death Benefit" section of this prospectus. The expense risk is our
obligation to cover the cost of issuing and administering Portfolio Director, no
matter how large the cost may be.
 
The Company may make a profit on the mortality and expense risk fee and on the
administration and distribution fee.
 
The administration and distribution fee is to reimburse the Company for our
administrative expenses for providing Variable Account Options. This includes
the expense of administration and marketing (including but not limited to
enrollment, participant communication and education).
For more information about the mortality and expense risk fee and administration
and distribution fee, see the Fee Table in this prospectus.
 
The mortality and expense risk fee or administration and distribution fee may be
reduced or waived if issued to certain types of plans that are expected to
result in lower costs to VALIC. To learn more about how we determine if the
mortality and expense risk fee or administration and distribution fee may be
reduced or waived, see the "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" section of this prospectus.
 
FUND ANNUAL EXPENSE CHARGE
 
Investment management charges based on a percentage of each Fund's average daily
net assets are payable by each Fund. Depending on the Variable Account Option
selected, the charges will be paid by each Fund to the Company, or to Dreyfus or
to Templeton. These charges and other Fund charges and expenses are fully
described in the prospectuses for the Funds. These charges indirectly cost you
because they lower your return.
 
OTHER TAX CHARGES
 
We reserve the right to charge for certain taxes (other than premium taxes) that
we may have to pay. This could include federal income taxes. Currently, no such
charges are being made.

REDUCTION OR WAIVER OF ACCOUNT
MAINTENANCE FEE, SURRENDER,
MORTALITY AND EXPENSE RISK OR ADMINISTRATION AND DISTRIBUTION FEE CHARGES
 
We may, as described below, determine that the account maintenance fee,
surrender charges, mortality and expense risk fee or administration and
distribution fee for Portfolio Director may be reduced or waived. We may reduce
or waive these fees and charges if we determine that your retirement program
will allow us to reduce or eliminate administrative or sales expenses that we
usually incur for retirement programs. There are a number of factors we will
review in determining whether your retirement program will allow us to reduce or
eliminate these administrative or sales expenses.
 
  -  The type of retirement program.
 
     Certain types of retirement programs because of their stability can result
     in lower administrative costs.
 
  - The nature of your retirement program.
 
    Certain types of retirement programs, due to the types of employees who
    participate, experience fewer account surrenders thus reducing
    administrative costs.
 
  - Other factors of which we are not presently aware which could reduce
    administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive account maintenance fees:
 
  - The frequency of Purchase Payments for your retirement program.
 
    Purchase Payments received no more than once a year can reduce
    administrative costs.
 
  - The administrative tasks performed by your employer for your retirement
    program.
 
    The employer sponsoring your retirement program can, through their method of
    remitting Purchase Payments, reduce administrative costs.
 
We review the following additional factors to determine whether we can reduce or
waive surrender charges:
 
  - The size of your retirement program.
 
    A retirement program which involves a larger group of employees may allow us
    to reduce sales expenses.
 
  - The total amount of Purchase Payments to be received for your retirement
    program.
 
    Larger Purchase Payments can reduce sales expenses.
 
  - The use of mass enrollment or related administrative tasks performed by your
    employer for your retirement program.
 
We review the following additional factors to determine whether we can reduce or
waive the mortality and expense risk fee or administration and distribution fee:
 
  - The frequency of Purchase Payments for your retirement program.
 
  - The size of your retirement program.
 
  - The amount of your retirement program's periodic purchase payment.
 
We will only do this if permitted by this Contract and by VALIC guidelines in
effect at the time. In no event will the reduction or waiver of fees be
permitted where the reduction or waiver will unfairly discriminate against any
person.
 
SEPARATE ACCOUNT EXPENSE
REIMBURSEMENT
 
Dreyfus Small Cap or its affiliate has an agreement with the Company to pay the
Company for certain administrative and shareholder services it provides to the
Fund. The Company will reduce its charges to the Division investing in the Fund
by the full amount of any of these payments it receives.

PAYOUT PERIOD
- --------------------------------------------------------------------------------
 
The Payout Period (Annuity Period) begins when you decide to retire or otherwise
withdraw your money in a steady stream of payments. If your employer's plan
permits, you may apply any portion of your Account Value to one of the types of
Payout Options listed below. You may choose to have your Payout Option on either
a fixed, a variable, or a combination payout basis. When you choose to have your
Payout Option on a variable basis, you may keep the same Variable Account
Options in which your Purchase Payments were made, or transfer to different
ones.
 
FIXED PAYOUT
Under Fixed Payout, you will receive payments from the Company. These payments
are fixed and guaranteed by the Company. The amount of these payments will
depend on:
 
  - Type and duration of Payout Option chosen;
 
  - Your age or your age and the age of your survivor (1);
 
  - Your sex or your sex and the sex of your survivor (1) (IRA's and certain
    nonqualified contracts);
 
  - The portion of your Account Value being applied; and
 
  - The payout rate being applied and the frequency of the payments.
 
  (1) This applies only to joint and survivor payouts.
 
If the benefit would be greater, the amount of your payments will be based on
the current payout rate the Company uses for immediate annuity contracts.
 
VARIABLE PAYOUT
   
With a Variable Payout, you may select from your existing Variable Account
Options. Your payments will vary accordingly. This is due to the varying
investment results that will be experienced by each of the Variable Account
Options you selected. The Payout Unit Value is calculated just like the Purchase
Unit Value for each Variable Account Option except that the Payout Unit Value
includes a factor for the Assumed Investment Rate you select. For additional
information on how Payout Payments and Payout Unit Values are calculated, see
the Statement of Additional Information.
    
 
   
In determining your first Payout Payment, an Assumed Investment Rate of 3 1/2%
is used (unless you select a higher rate as allowed by state law.) If the net
investment experience of the Variable Account Option exceeds your Assumed
Investment Rate, your next payment will be greater than your first payment. If
the investment experience of the
    
 
Variable Account Option is lower than your Assumed Investment Rate, your next
payment will be less than your first payment.
 
COMBINATION FIXED AND VARIABLE PAYOUT
With a Combination Fixed and Variable Payout, you may choose:
 
   
  - From your existing Variable Account Options (payments will vary); with a
    
 
   
  - Fixed Payout (payment is fixed and guaranteed).
    
 
   
Up to seven Variable Account Options may be chosen, or up to six Variable
Account Options if the Fixed Payout is chosen.
    
 
PAYOUT DATE
The Payout Date is the date elected by you on which your payout (annuity)
payments will start. The date elected must be the first of any month provided 30
days advance notice has been given to VALIC. Your account will be valued ten
days prior to the end of the month preceding the Payout Date. A request to start
payments must be sent to our Home Office on a form approved by VALIC. Generally,
for qualified contracts, the Payout Date may begin when you attain age 59 1/2 or
separate from service, but must begin no later than April 1 following the
calendar year you reach age 70 1/2 or the calendar year in which you retire. For
nonqualified contracts, the Payout Date may begin at any time prior to your 85th
birthday. For additional information on the minimum distribution rules that
apply to payments under 403(b), 401, 403(a) and 457 plans or simplified employee
plans ("SEPs"), see "Federal Tax Matters" in this prospectus and in the
Statement of Additional Information.
 
PAYOUT OPTIONS
You may specify the manner in which your Payout Payments are made. You may
select one of the following options:
 
  - LIFE ONLY -- payments are made only to you during your lifetime. Under this
    option there is no provision for a death benefit for the beneficiary. For
    example, it would be possible under this option for the Annuitant to receive
    only one payout payment if he died prior to the date of the second payment,
    two if he died before the third payment.
 
  - LIFE WITH GUARANTEED PERIOD -- payments are made to you during your
    lifetime; but if you die before the guaranteed period has expired, your
    beneficiary will receive payments for the rest of your guaranteed period.
 
PAYOUT UNIT -- a measuring
unit used to calculate Payout
Payments from your Variable
Account Option. Payout Unit
values will vary with the
investment experience of the
VALIC Separate Account A
Division you have selected.
 
ASSUMED INVESTMENT
RATE -- the rate used to
determine your first monthly
Payout Payment per
thousand dollars of Account
Value in your Variable
Account Option(s).
 
                                                                              25
<PAGE>   532
- --------------------------------------------------------------------------------
 
  - LIFE WITH CASH OR UNIT REFUND -- payments are made to you during your
    lifetime. Upon your death, your beneficiary will receive a lump sum payment
    equal to the remaining Annuity Value.
 
  - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
    lifetime of you and your beneficiary. Upon the death of one, payments
    continue during the lifetime of the survivor. This option is designed
    primarily for couples who require maximum possible variable payouts during
    their joint lives and are not concerned with providing for beneficiaries at
    death of the last survivor. For example, it would be possible under this
    option for the Joint Annuitants to receive only one payment if both
    Annuitants died prior to the date of the second payment, or for the Joint
    Annuitants to receive only one payment and the surviving Annuitant to
    receive only one payment if one Annuitant died prior to the date of the
    second payment and the surviving Annuitant dies prior to the date of the
    third payment.
 
  - PAYMENT FOR A DESIGNATED PERIOD -- payments are made to you for a select
    number of years between five and thirty. Upon your death, payments will
    continue to your beneficiary until the designated period is completed.
 
ENHANCEMENTS TO PAYOUT OPTIONS
You may be able to select enhancements to the Payout Options described above.
These enhancements include partial annuitization, flexible payments of varying
amounts and inflation protection payments. Additionally, certain options may be
available with a one to twenty year guaranteed period. Additionally, certain
options may be available with a one to twenty year guaranteed period. The Joint
and Survivor Life Option may be available with a one to twenty year guaranteed
period option. Not all of the enhancements are available under each option.
 
PAYOUT INFORMATION
   
Once your Payout Payments have begun, the option you have chosen may not be
stopped or changed. Any one of the Variable Account Options may result in your
receiving unequal payments during your life expectancy. If payments begin before
age 59 1/2, you may suffer unfavorable tax consequences, in the form of an
excise tax, if you do not meet an exception under federal tax law. See "Federal
Tax Matters" in this prospectus.
    
 
Your Payment Option should be selected at least 30 days before your Payout Date.
If such selection is not made:
 
  - Payments will be made under the Life with Guaranteed Period Option, and
 
   
  - The payments will be guaranteed for a 10 year period,
    
 
  - The payments will be based on the allocation used for your Purchase
    Payments,
 
   
  - Fixed Account Option will be used to distribute payments to you on a Fixed
    Payout basis, and
    
 
  - Variable Account Options will be used to distribute payments to you on a
    Variable Payout basis.
 
Your first Payout Payment must total at least $25.
 
   
Most Payout Payments are made monthly. If the amount of your payment is less
than $25, we reserve the right to reduce the number of payments made each year
so each of your payments are at least $25, subject to any limitations under the
contract or plan.

PAYOUT OPTIONS OR

Additional Information".

SURRENDER OF ACCOUNT VALUE
- --------------------------------------------------------------------------------
 
WHEN SURRENDERS ARE ALLOWED
You may withdraw all or part of your Account Value at any time before the Payout
Period begins if:
 
  - allowed under federal and state law; and
 
  - allowed under your employer's plan.
 
For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.
 
AMOUNT THAT MAY BE SURRENDERED
The amount that may be surrendered at any time can be determined as follows:
 
<TABLE>
<S>                    <C>               <C>
                                               Your
                                              Account
       Allowed                               Value(1)
      Surrender           = (EQUALS)         - (MINUS)
        Value                             Any Applicable
                                             Surrender
                                              Charge
</TABLE>
 
  1: Equals the Account Value next computed after your properly completed
     request for surrender is received in our Home Office.
 
There is no guarantee that the Surrender Value in a Variable Account Option will
ever equal or exceed the total amount of your Purchase Payments received by us.
 
   
We will mail to you the Surrender Value within 7 calendar days after we receive
your properly completed surrender request at our Home Office. However, we may be
required to suspend or postpone payments if redemption of an underlying Fund's
shares have been suspended or postponed. See your current Fund(s)' prospectuses
for a discussion of the reasons why the redemption of shares may be suspended or
postponed.
    
 
We may receive a surrender for a Purchase Payment which has not cleared the
banking system. We may delay payment of that portion of your Surrender Value
until the check clears. The rest of the Surrender Value will be processed as
usual.
 
SURRENDER RESTRICTIONS
Generally, Internal Revenue Code Section 403(b)(11) permits total or partial
distributions from a 403(b) contract only on account of hardship (employee
contributions only without accrued interest), attainment of age 59 1/2,
separation from service, death or disability.
 
Under the TEXAS STATE OPTIONAL RETIREMENT PROGRAM, and in many Section 403(b)
contracts, no surrender or partial surrender will be allowed except for
termination of employment, retirement or death.
 
Under the FLORIDA STATE OPTIONAL RETIREMENT PROGRAM, no surrender or partial
surrender of Purchase Payments made by the employer will be allowed except for
termination of employment, retirement or death. Benefit payments based on
payments from the employer may not be paid in a lump sum or for a period
certain, but must be paid under a life contingency option, except for:
 
  - death benefits; and
 
  - certain small amounts approved by the State of Florida.
 
   
Under the LOUISIANA OPTIONAL RETIREMENT PLAN retirement benefits must be paid in
the form of a lifetime income, and except for death benefits, single sum
surrenders and partial surrenders out of the plan are not permitted.
    
 
   
Other employer-sponsored plans may also impose restrictions on the timing and
form of surrenders from the contract.
    
 
PARTIAL SURRENDERS
   
You may request a partial surrender of your Account Value at any time, subject
to any applicable surrender restrictions. A partial surrender plus any surrender
charge will reduce your Account Value. Partial surrenders will be paid from the
Fixed Account Option first unless otherwise specified by you.
    
 
The reduction in the number of Purchase Units credited to your Variable Account
Option Account Value will equal:
 
<TABLE>
<S>                    <C>               <C>
     The amount                            Your Purchase
     surrendered                            Units next
  from the Variable                       computed after
   Account Option                           the written
      + (PLUS)          / (DIVIDED BY)      request for
    Any Surrender                          surrender is
       Charge                             received at our
                                           Home Office.
</TABLE>
 
The Surrender Value will be reduced by a full quarterly account maintenance fee
charged in the case of a full surrender during a quarter.
 
SYSTEMATIC WITHDRAWALS
You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your annuity contract offered by Portfolio
Director. There will be no surrender charge for withdrawals using this method,
which provides for:
 
  - Payments to be made to you;
 
  - Payment over a stated period of time (but not less than five years);
 
  - Payment of a stated yearly dollar amount or percentage (the amount or
    percentage may not exceed 20% of your Account Value at the time election is
    made).
 
We may require a minimum withdrawal amount under this method. The portion of
your account that has not been withdrawn will continue to receive the investment
return of the Variable Account Options which you selected. A systematic
withdrawal election may not be changed but can be revoked at no charge. Once
revoked, a systematic withdrawal may not be
 
                                                                              27

- --------------------------------------------------------------------------------
 
elected again. No more than one systematic withdrawal election may be in effect
at any one time. We reserve the right to discontinue any or all systematic
withdrawals or to change its terms, at any time.
 
DISTRIBUTIONS REQUIRED BY FEDERAL TAX LAW. There will be no surrender charge on
a minimum distribution required by federal tax law (known as No Charge Minimum
Distribution), if the withdrawal:
 
  - Is made payable to you; and
 
  - Does not exceed the amount required under federal tax law as determined by
    the values in your Portfolio Director Contract and VALIC.
 
This contract feature will not be available in any year that an amount has been
withdrawn under the no charge systematic withdrawal method. See "Federal Tax
Matters" in this prospectus and in the Statement of Additional Information for
more information about required distributions imposed by tax law.
 
For an explanation of possible adverse tax consequences of a surrender, see
"Federal Tax Matters" in this prospectus and in the Statement of Additional
Information.

EXCHANGE PRIVILEGE
- --------------------------------------------------------------------------------
 
   
We issue other fixed and/or variable annuity contracts (other contracts) in
addition to Portfolio Director. These other contracts are listed below. We will
allow you, under certain conditions, to exchange from one of these other
contracts to Portfolio Director. This exchange privilege will be available only
to other contracts purchased through your employer-sponsored retirement plan and
for which we have not yet started making payments under a Payout Option. If you
elect to exercise one of these exchange offers, you should contact any of our
Regional Offices at the addresses shown in the back of this prospectus. An
exchange may require the issuance of a Contract or may be subject to any other
requirements that the Company may impose.
    
 
RESTRICTIONS ON EXCHANGE PRIVILEGE
 
We will impose certain general restrictions and rules on the exchange
privileges.
 
  - Partial exchanges are not permitted.
 
   
  - Exchanges from Portfolio Director to contract forms other than Portfolio
    Director 2 and Portfolio Director Plus are not permitted.
    
 
  - This exchange privilege is only available for those other contracts listed
    below.
 
Additionally, if you have your money in a fixed account of one of the below
listed other contracts, you must exchange directly into the Fixed Account
Options of Portfolio Director. You will be subject to all of the rules that
apply to the Fixed Account Options in Portfolio Director. For example, you will
be subject to the rules concerning transfers among investment options as stated
in the Transfers Between Investment Options section in this prospectus. We may,
at our option, waive any transfer restrictions for a stated period of time. If
we waive these transfer restrictions, you will be allowed to exchange to any
investment option available in Portfolio Director.
 
WE RESERVE THE RIGHT TO TERMINATE, MODIFY OR SUSPEND THESE EXCHANGE PRIVILEGES
AT ANY TIME.
 
TAXES AND CONVERSION COSTS
 
We will impose no fee or charge for these exchanges. Please read the "Federal
Tax Matters" section in this prospectus for information about the federal income
tax treatment of Portfolio Director.
 
SURRENDER CHARGE
 
We will generally not impose nor waive existing surrender charges as a result of
your electing to exchange from one of the other contracts.
 
For purposes of determining surrender charges, we often consider time in the
contract. For SPQ181 and SPQ181-1 Contracts, the contract date for determining
surrender charges under Portfolio Director will be the SPQ181 and SPQ181-1
contract date plus one year. For example, if you have an SPQ181 contract with a
contract date of January 1, 1993, upon exchange into Portfolio Director, the
contract date for surrender charges purposes becomes January 1, 1994.
 
For any other contract, the contract date for determining surrender charges
under Portfolio Director will be the same date as the other contract, but no
earlier than January 1, 1982. (The effect of this is to potentially shorten the
charge period for Purchase Payments subsequently made to Portfolio Director.)
 
If there is no surrender charge on assets within another contract, we will not
impose charges on those assets as a result of an exchange. If surrender charges
are to be based on Purchase Payments within a contract, we will consider
purchase payments in the other contract to have been transferred to Portfolio
Director for purposes of calculating the surrender charge. The effective dates
of these Purchase Payments will also be retained for surrender charge purposes.
 
The Portfolio Director surrender charge is calculated assuming the most recent
Purchase Payments are removed first. This policy may cause exchanged funds to be
accessible only after charges are imposed.
 
EXCHANGE OFFERS FOR CONTRACTS OTHER THAN PORTFOLIO DIRECTOR AND PORTFOLIO
DIRECTOR 2
 
The following other contracts may be exchanged.
 
  - V-Plan Contracts (IFA-582 and GFA-582 Contracts)

comparison of the features, charges, and restriction between each above listed
other
contract and Portfolio Director is provided in the Statement of Additional
Information.
 
For the V-Plan and Compounder Contract you should refer to the terms of the
contract or certificate. For the other contracts please refer to its most
recently dated prospectus for a complete description of the contract terms and
conditions. Those prospectuses are incorporated herein by reference. If you want
an additional copy of any of these prospectuses or Statements of Additional
Information, please contact us at the address shown in the introduction of the
prospectus.
 
FEATURES OF PORTFOLIO DIRECTOR
 
In deciding whether you want to exercise this exchange privilege, you should
consider the following features of Portfolio Director.
 
  - Portfolio Director has more investment options to select from.
 
  - The Portfolio Director surrender charge is calculated assuming the most
    recent Purchase Payments are removed first. This policy may cause exchanged
    funds to be accessible only after charges are imposed.
 
  - Portfolio Director has an Interest Guaranteed Death Benefit.
 
  - Portfolio Director's Fund fees and charges are different than the other
    contracts and in some cases may be higher.
 
  - Portfolio Director's guaranteed annuity rates and guaranteed interest rates
    may be less favorable than the other contracts.
 
AGENTS' AND MANAGERS' RETIREMENT PLAN
EXCHANGE OFFER
 
General. All eligible agents and managers of the Company are allowed to
participate in the Company's Agents' and Managers' Retirement Plan ("Plan"). We
grant to participants in the Plan the right to effect a voluntary exchange of
their units of interest under the SA-1 Contracts or Independence Plus Contracts
for the equivalent units of interest in Portfolio Director.
 
Agents and managers of VALIC who enter into the voluntary exchange will not
incur under Portfolio Director any surrender charges or account maintenance
fees. Other individuals who may exchange to Portfolio Director from SA-1 or
Independence Plus Contracts may have surrender charges and account maintenance
fees imposed under Portfolio Director. All other provisions with regard to
exchange offers referenced in the section entitled "Exchange Offers" will apply
to the Agents' and Managers' Retirement Plan Exchange Offer.
 
Pursuant to this voluntary exchange offer, participants in the Plan will have
three options to choose from. As to the funding vehicle for their purchase
payment plan, the participant may choose to:
 
  - Remain in the SA-1 Contract or Independence Plus Contract.
 
  - Leave current assets in the SA-1 Contract or Independence Plus Contract and
    direct future Purchase Payments to the Portfolio Director; or
 
  - Transfer all current assets and future Purchase Payments to the Portfolio
    Director.
 
If the participant chooses to remain in either the SA-1 Contract or Independence
Plus Contract, future Purchase Payments and current assets will be controlled by
the provisions of the SA-1 Contract or Independence Plus Contract, respectively.
If the participant chooses to leave current assets in the SA-1 Contract or the
Independence Plus Contract and direct future Purchase Payments to Portfolio
Director, the current assets will be controlled by the provisions of the SA-1
Contract or the Independence Plus Contract, respectively. The future Purchase
Payments will be controlled by the terms of Portfolio Director subject to the
exception that surrender charges and account maintenance fees will not be
imposed under Portfolio Director. If the participant chooses to transfer all
current assets and future Purchase Payments to Portfolio Director, such current
assets and future Purchase Payments will be controlled by the provisions of
Portfolio Director subject to the exception that surrender charges and account
maintenance fees will not be imposed under Portfolio Director.
 
Once a participant transfers assets and future Purchase Payments to Portfolio
Director the participant will not be permitted to exchange back to the SA-1
Contract or Independence Plus Contract. If a participant chooses to transfer
future Purchase Payments but not current assets to Portfolio Director, the
participant will be allowed at a later date to transfer the current assets to
Portfolio Director. For a complete analysis of the differences between the SA-1
contract or the Independence Plus Contract and Portfolio Director, you should
refer to the Statement of Additional Information and the form of the contract or
certificate for its terms and conditions.

DEATH BENEFITS
- --------------------------------------------------------------------------------
 
Portfolio Director will pay death benefits during either the Purchase Period or
the Payout Period. How these death benefits will be paid are discussed below.
The death benefit provisions in Portfolio Director may vary from state to state.
 
BENEFICIARY INFORMATION
 
The Beneficiary may receive death benefits:
 
- - In a lump sum; or
 
- - In the form of an annuity under any of the Payout Options stated in the Payout
  Period section of this prospectus subject to the restrictions of that Payout
  Option.
 
   
Payment of any death benefits must be within the time limits set by federal tax
law and by the plan, if any.
    
 
Beneficiaries Other Than Spouses.
 
If the Beneficiary is not the spouse of the Annuitant, death benefits must be
paid.
 
- - In full within 5 years after the Annuitant's death; or
 
- - By payments beginning within 1 year after the Annuitant's death under:
 
  - A life annuity;
 
  - A life annuity with payments certain; or
 
   
  - An annuity for a designated period not exceeding the Beneficiary life
    expectancy.
    
 
If the Annuitant dies before the Annuity Date, the Beneficiary as named by you
may receive the payout.
 
Payments certain or payments for a designated period cannot be for a greater
period of time than the Beneficiary's life expectancy. After choosing a payment
option, a Beneficiary may exercise many of the investment options and other
rights that the Participant or Contract Owner had under Portfolio Director.
 
SPECIAL INFORMATION FOR INDIVIDUAL
NON-TAX QUALIFIED CONTRACTS
 
It is possible that the Contract Owner and the Annuitant under a Non-Tax
Qualified Contract are not the same person. If this is the case, and the
Contract Owner dies, there will be no death benefit payable since the death
benefit is only due in the event of the Annuitant's death. However, the Contract
will be transferred to the Contingent Owner, if any, or to the Contract Owner's
estate. Such transfers will be considered a taxable event by the IRS.
 
DURING THE PURCHASE PERIOD
 
Two types of benefits are available if death occurs during the Purchase Period.
Interest Guaranteed Death Benefit and Standard Death Benefit.
 
INTEREST GUARANTEED DEATH BENEFIT
 
The interest guaranteed death benefit is payable when death occurs prior to your
reaching the age of 70. This contract provision is not available in some states.
 
The amount payable under the interest guaranteed death benefit will be at least
equal to the sum of your Account Value in the Fixed Account Option(s) and the
Variable Account Option(s) on the date VALIC receives proof of death.
 
Here is how to calculate the death benefit:
Step 1: Determine your Fixed Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Fixed Account Option on date
  proof of death Is received by VALIC
  OR
  100% of Purchase Payments placed
  in Fixed Account Option
- - (minus)
  Amount of all prior withdrawals, charges and
  any portion of Account Value applied under
  a Payout Option
</TABLE>
 
Step 2: Determine your Variable Account Option Value by taking the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Value of Variable Account Option on date
  proof of death is received by VALIC
  OR
  100% of Purchase Payments placed in
  Variable Account Options
- - (minus)
  Prior withdrawals (out of) or transfers
  (out of) the Variable Account Option
+ (plus)
  Interest at an annual rate of 3%
</TABLE>
 
Step 3: Add step 1 + 2 = Death Benefit
 
   
For purposes of this calculation amounts transferred into the Variable Account
Option will be treated as Purchase Payments.
 
BENEFICIARY -- the person
    
   
designated to receive Payout
    
   
Payments upon the death of
    
   
an Annuitant.
    
 
   
ANNUITANT -- the individual,
    
   
(in most cases this person is
    
   
you) to whom Payout
    
   
Payments will be paid.
    
 
   
CONTRACT OWNER -- either
    
   
your employer or organization
    
   
in the case of a group

individual non-qualified type,
    
   
this is generally the Annuitant
    
   
but is not required to be.
    
   
Also, a Contingent Contract
    
   
Owner may be designated.
    
 
   
FIXED ACCOUNT OPTIONS -- a
    
   
particular subaccount into
    
   
which your Purchase
    
   
Payments and Account Value
    
   
may be allocated to fixed

STANDARD DEATH BENEFIT
 
The standard death benefit is payable if death occurs on or after age 70.
 
The Standard Death Benefit will be the greater of:
 
<TABLE>
<S>                     <C>  <C>
  Your Account Value on the Date Proof of Death is
  Received by VALIC
  OR

  and/or Variable Account Options)
- -- (MINUS)
  Amount of all Prior Withdrawals, Charges
  and any portion of Account Value applied
  under a Payout Option
</TABLE>
 
DURING THE PAYOUT PERIOD
 
If death occurs during the Payout Period, your Beneficiary may receive a death
benefit depending on the Payout Option selected. The amount of death benefits
will also depend on the Payout Option that you selected. The Payout Options
available in Portfolio Director are described in the "Payout Period" section of
this prospectus.
 
  - If the Life Only Option or Joint and Survivor Life Option were chosen, there
    will be no death benefit.
 
  - If the Life With Guaranteed Period Option, Joint and Survivor Life with
    Guaranteed Periods Option, Life with Cash or Unit Refund Option or Payment
    for a Designated Period Option were chosen, and the entire amount guaranteed
    has not been paid, the Beneficiary may choose one of the following within 60
    days after death benefits are payable:
 
     - Receive the present value of any remaining payments in a lump sum; or
 
     - Receive the remaining payments under the same terms of the guaranteed
       period option chosen by the deceased Participant; or
 
     - Receive the present value of any remaining payments applied under the
       Payment for a Designated Period Option for a period equal to or shorter
       than the period remaining. Spouse beneficiaries may be entitled to more
       favorable treatment under federal tax law.

HOW TO REVIEW INVESTMENT PERFORMANCE OF SEPARATE ACCOUNT DIVISIONS
- --------------------------------------------------------------------------------
 
We will advertise information about the investment performance of VALIC Separate
Account A Divisions. Our advertising of past investment performance results does
not mean that future performance will be the same. The performance information
will not predict what your actual investment experience will be in that Division
or show past performance under an actual contract. We may also show how the
Divisions rank on the basis of data compiled by independent ranking services.
 
   
Some of the Divisions (and underlying Funds) offered in this prospectus were
previously available through other annuity contracts before Portfolio Director
was first available to you. We may therefore, advertise investment performance
since the inception of the underlying Funds. In each case, we will use the
charges and fees imposed by Portfolio Director in calculating the Division's
investment performance.
    
 
TYPES OF INVESTMENT PERFORMANCE INFORMATION ADVERTISED
 
We may advertise the Division's Total Return Performance information and Yield
Performance information.
 
TOTAL RETURN PERFORMANCE INFORMATION
 
Total Return Performance Information is based on the overall dollar or
percentage change in value of an assumed investment in a Division over a given
period of time.
 
There are seven ways Total Return Performance Information may be advertised:
 
  - Standard Average Annual Total Return
  - Nonstandard Average Annual Total Return
  - Cumulative Total Return
  - Annual Change in Purchase Unit Value
  - Cumulative Change in Purchase Unit Value
  - Total Return Based on Different Investment Amounts
  - An Assumed Account Value of $10,000
 
Each of these is described below.
 
STANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Standard Average Annual Total Return shows the average percentage change in the
value of an investment in the Division from the beginning to the end of a given
historical period. The results shown are after all charges and fees have been
applied against the Division. This will include account maintenance fees and
surrender charges that would have been deducted if you surrendered Portfolio
Director at the end of each period shown. Premium taxes are not deducted. This
information is calculated for each Division based on how an initial assumed
payment of $1,000 performed at the end of 1, 3, 5 and 10 year periods. If
Standard Average Annual Return for a Division is not available for a stated
period, we may show the Standard Average Annual Return since Division inception.
    
 
   
The return for periods of more than one year are annualized to obtain the
average annual percentage increase (or decrease) during the period.
Annualization assumes that the application of a single rate of return each year
during the period will produce the ending value, taking into account the effect
of compounding.
    
 
NONSTANDARD AVERAGE ANNUAL TOTAL RETURN
 
   
Nonstandard Average Annual Total Return is calculated in the same manner as the
Standard Average Annual Total Return. However, Nonstandard Average Annual Total
Return shows only the historic investment results of the Division. Account
maintenance fees, surrender charges and premium taxes are not deducted. The SEC
staff takes the position that performance information of an underlying Fund
reduced by account fees for a period prior to the inception of the corresponding
Division is nonstandard performance information regardless of whether all
account fees and charges are deducted.
    
 
CUMULATIVE TOTAL RETURN
 
   
Cumulative Total Return assumes the investment in Portfolio Director will stay
in the Division beyond the time that a surrender charge would apply. It may be
calculated for 1, 3, 5 and 10 year periods. If Cumulative Total Return for a
Division is not available for a stated period, we may show the Cumulative Total
Return since Division inception. It is based on an assumed initial investment of
$10,000. The Cumulative Return will be calculated without deduction of account
maintenance fees, surrender charges or premium taxes.
    
 
ANNUAL CHANGE IN PURCHASE UNIT VALUE
 
   
Annual Change in Purchase Unit Value is a percentage change during a one year
period or since inception. This is calculated as follows:
    
 
   
  - The Purchase Unit Value at the start of the year is subtracted from the
    Purchase Unit Value at the end of the period or year;
    
 
   
  - The difference is divided by the Purchase Unit Value at the start of the
    period or year.
    
 
   
Account maintenance fees, surrender charges and premium taxes are not deducted.
The effect of these charges, if deducted, would reduce the Division's Annual
Change in Purchase Unit Value.
 
DIVISIONS -- subaccounts of
    
VALIC Separate Account A
which represent the Variable
Account Options in Portfolio
Director. Each Division
invests in a different mutual
fund, each having its own
investment objective and
strategy.
 
PURCHASE PAYMENTS -- an
amount of money you pay to
VALIC to receive the benefits
of an annuity Contract offered
by Portfolio Director.

TOTAL RETURN PERFORMANCE
INFORMATION is calculated

performance information, see
the Statement of Additional
Information.
 
                                                                              33
<PAGE>   540
 
- --------------------------------------------------------------------------------
 
CUMULATIVE CHANGE IN PURCHASE UNIT VALUE
 
Cumulative Change in Purchase Unit Value is a percentage change from the
beginning to the ending of a period usually greater than one year. Otherwise, it
is calculated in the same way as the Annual Change in Purchase Unit Value.
 
TOTAL RETURN BASED ON DIFFERENT INVESTMENT AMOUNTS
 
We may show total return information based on different investment amounts. For
example, we may show $200 a month for 10 years, or $100 a month to age 65. Fees
may or may not be included. Each performance illustration will explain the
Portfolio Director charges and fees imposed on the Division.
 
AN ASSUMED ACCOUNT VALUE OF $10,000
 
We may show annual values based on an initial investment of $10,000. This will
not reflect any deduction for account maintenance fees, surrender charges and
premium taxes.
 
YIELD PERFORMANCE INFORMATION
 
We may advertise Yield Performance, at a given point in time. A Division's yield
is one way of showing the rate of income the Division is earning as a percentage
of the Division's Purchase Unit Value.
 
AGSPC MONEY MARKET DIVISION
 
We may advertise the AGSPC Money Market Division's Current Yield and Effective
Yield.
 
   
The Current Yield refers to the income produced by an investment in the AGSPC
Money Market Division over a given 7-day period. The Current Yield does not take
into account surrender charges, account maintenance fees or premium taxes. The
income produced over a 7 day period is then "annualized." This means we are
assuming the amount of income produced during the 7-day period will continue to
be produced each week for an entire year. The annualized amount is shown as a
percentage of the investment. The annualized 7-day Current Yield for the last 7
days ended December 31, 1998 was 3.64%.
    
 
   
The Effective Yield is calculated in a manner similar to the Current Yield. But,
when the yield is annualized the income earned is assumed to be reinvested. The
compounding effect will cause the Effective Yield to be higher than the Current
Yield. The annualized 7-day Effective Yield for the last 7 days ended December
31, 1998 was 3.71%.
    
 
DIVISIONS OTHER THAN THE AGSPC MONEY MARKET DIVISION
 
We may advertise the standardized yield performance for each Division other than
the AGSPC Money Market Division. The yield for each of these Divisions will be
determined as follows:
 
  - We will subtract the account maintenance fee from the average daily net
    investment income per Purchase Unit;
 
  - We will divide the remainder by the Purchase Unit Value on the last day of
    the period; and
 
  - We will annualize the result.
 
PERFORMANCE INFORMATION
 
AVERAGE ANNUAL TOTAL RETURN, CUMULATIVE RETURN AND ANNUAL AND CUMULATIVE CHANGE
IN PURCHASE UNIT VALUE TABLES.
 
   
In the sections above we have described a number of ways we may advertise
information about the investment performance of VALIC Separate Account A
Divisions. Certain performance information for each VALIC Separate A Account
Division is printed in the eight tables below.
    
 
The information presented does not reflect the advantage under Portfolio
Director of deferring federal income tax on increases in Account Value due to
earnings attributable to Purchase Payments (see "Federal Tax Matters" in the
prospectus and in the Statement of Additional Information.) The information
presented also does not reflect the advantage under Qualified Contracts of
deferring federal income tax on Purchase Payments.
 
The performance results shown in the following tables are not an estimate or
guarantee of future investment performance, and do not represent the actual
experience of amounts invested by a particular Participant.

(1) The Division commenced operations on October 13, 1982 as the Capital
    Accumulation Fund. Effective October 1, 1991, the Fund underlying the AGSPC
    MidCap Index Division changed its name from the Capital Accumulation Fund to
    the MidCap Index Fund and amended its investment objective, investment
    program and investment restrictions accordingly. The performance figures for
    the AGSPC MidCap Index Division reflect the performance of the MidCap Index
    Fund since October 1, 1991.
 
   
(2) For periods prior to 1994, the Annual and Cumulative Change in Purchase Unit
    Value figures are based on the average and cumulative changes in Purchase
    Unit Value for a stated period in a corresponding Division of Separate
    Account A for a different Contract offered by the Company and have been
    restated to take into account the fees and charges under Portfolio Director
    other than the surrender charge and account maintenance fee. The Contracts
    offered by this prospectus became available for purchase on July 11, 1994.

OTHER CONTRACT FEATURES
- --------------------------------------------------------------------------------
 
CHANGES THAT MAY NOT BE MADE
 
The following terms in Portfolio Director may not be changed once your account
has been established:
 
  - The Contract Owner;
 
  - The Participant; and
 
  - The Annuitant.
 
CHANGE OF BENEFICIARY
 
The Beneficiary (if not irrevocable) may usually be changed at any time.
 
Under some retirement programs, the right to name or change a Beneficiary is
subject to approval by the spouse. Also, the right to name a Beneficiary other
than the spouse may be subject to certain tax laws and regulations.
 
If the Annuitant dies, and there is no Beneficiary, any death benefit will be
payable to the Annuitant's estate.
 
If a Beneficiary dies while receiving payments, and there is no co-Beneficiary
to continue to receive payments, any amount still due will be paid to the
Beneficiary's estate.
 
CONTINGENT OWNER
 
The Contract Owner may name a Contingent Owner under an individual non-tax
qualified Contract. During the Purchase Period, the Contingent Owner may be
changed. However, if the Contract Owner dies, benefits must be distributed as
required by the federal tax law.
 
CANCELLATION -- THE 20 DAY "FREE LOOK"
 
The Contract Owner may cancel an individual contract by returning it to the
Company within 20 days after delivery. (A longer period will be allowed if
required under state law.) A refund will be made to the Contract Owner within 7
days after receipt of the Contract within the required period. The amount of the

under state law, if larger.
 
WE RESERVE CERTAIN RIGHTS
 
We reserve the right to:
  - Amend the Contract to conform with substitutions of investments;

    to new Participants after the effective date of the changes;

    the Act, in consideration of an investment management fee or in any other
    form permitted by law;

    longer required;

should always refer to the terms and conditions in your employer's plan when

VOTING RIGHTS
- --------------------------------------------------------------------------------
 
As discussed in the "About VALIC Separate Account A" section of this prospectus,
VALIC Separate Account A holds on your behalf shares of the Funds which comprise
the Variable Account Options. From time to time the Funds are required to hold a
shareholder meeting to obtain approval from their shareholders for certain
matters. As a Participant, you may be entitled to give voting instructions to us
as to how VALIC Separate Account A should vote its Fund shares on these matters.
Those persons entitled to give voting instructions will be determined before the
shareholders meeting is held. For more information about these shareholder
meetings and when they may be held, see the Funds' prospectuses.
 
WHO MAY GIVE VOTING INSTRUCTIONS
 
In most cases during the Purchase Period, you will have the right to give voting
instructions for the shareholder meetings. This will be true even if your
employer is the Contract Owner. Contract Owners will instruct VALIC Separate
Account A in accordance with these instructions. You will receive proxy material
and a form on which voting instructions may be given before the shareholder
meeting is held.
 
You will not have the right to give voting instructions if Portfolio Director
was issued in connection with a nonqualified and unfunded deferred compensation
plan.
 
DETERMINATION OF FUND SHARES
ATTRIBUTABLE TO YOUR ACCOUNT
 
DURING PURCHASE PERIOD
 
The number of Fund shares attributable to your account will be determined on the
basis of the Purchase Units credited to your account on the record date set for
the Fund shareholder meeting.
 
DURING PAYOUT PERIOD OR AFTER A DEATH
BENEFIT HAS BEEN PAID
 
The number of Fund shares attributable to your account will be based on the
liability for future variable annuity payments to your payees on the record date
set for the Fund shareholder meeting.
 
HOW FUND SHARES ARE VOTED
 
The Funds which comprise the Variable Account Options in Portfolio Director may
have a number of shareholders including VALIC Separate Account A, VALIC and
other affiliated insurance company separate accounts and retirement plans within
the American General group of companies.
 
VALIC Separate Account A will vote all of the shares of the Funds it holds based
on, and in the same proportion as, the instructions given by all the
Participants invested in that Fund entitled to give instructions at that
shareholder meeting. VALIC Separate Account A will vote the shares of the Funds
it holds for which it receives no voting instruction in the same proportion as
the shares for which voting instructions have been received.
 
VALIC will vote the shares of the Funds it holds based on, and in the same
proportion as, the voting instructions received from participants in VALIC
Separate Account A.
 
In the future, we may decide how to vote the shares of VALIC or VALIC Separate
Account A in a different manner if permitted at that time under federal
securities law.

FEDERAL TAX MATTERS
- --------------------------------------------------------------------------------
 
Portfolio Director Contracts provide tax-deferred accumulation over time, but
are subject to federal income and excise taxes, mentioned briefly below. You
should refer to the Statement of Additional Information for further details.
Section references are to the Internal Revenue Code ("Code"). We do not attempt
to describe any potential estate or gift tax, or any applicable state, local or
foreign tax law other than possible premium taxes mentioned under "Premium Tax
Charge." Remember that future legislation could modify the rules discussed
below, and always consult your personal tax adviser regarding how the current
rules apply to your specific situation.
 
TYPE OF PLANS
 
   
Tax rules vary, depending on whether the Contract is offered under your
employer's tax-qualified retirement program or 408(b) IRA, as a Section 408(b)
Individual Retirement Annuity ("IRA"), or is instead a nonqualified Contract.
Portfolio Director is used under the following types of retirement arrangements:
    
 
  - Section 403(b) annuities for employees of public schools and Section
    501(c)(3) tax-exempt organizations;
 
  - Section 401(a) and 403(a) qualified plans of employers (including
    self-employed individuals);
 
   
  - Section 408(b) IRAs;
    
 
  - Section 457 deferred compensation plans of governmental and tax-exempt
    employers;
 
   
  - Section 408(k) SEPs;
    
 
  - Unfunded, non-qualified deferred compensation plans of private employers.
 
  - Section 408(p) SIMPLE Retirement Accounts
 
   
Portfolio Director may also be available through a nondeductible Section 408A
"Roth" individual retirement annuity ("Roth IRA").
    
 
Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.
 
In addition, Portfolio Director is also available through "Non-Qualified
Contracts." Separate Account investment must be "adequately diversified" in
order for the increase in the value of Non-Qualified Contracts to receive
tax-deferred treatment. Each Fund must, as of the end of each calendar quarter
or within 30 days thereafter, have no more than 55% of its assets invested in
any one investment, 70% in any two investments, 80% in any three investments and
90% in any four investments. A Fund's failure to meet these diversification
requirements could result in tax liability to Non-Qualified Contract Owners.
Since each Fund expects to satisfy diversification, and assure tax deferred
treatment to Non-Qualified Contract holders, investment opportunities of a Fund
may consequently be limited. This would affect all Contract Owners, including
owners of Contracts other than Non-Qualified Contracts for whom diversification
is not a requirement for tax-deferred treatment.
 
TAX CONSEQUENCES IN GENERAL
 
Purchase Payments, distributions, withdrawals, transfers and surrender of a
Contract can each have a tax effect, which varies with the governing retirement
arrangement. Please refer to the detailed explanation in the Statement of
Additional Information, the documents (if any) controlling the retirement
arrangement through which the contract is offered, and your personal tax
adviser.
 
Purchase Payments under Portfolio Director can be made as contributions by
employers, or as pre-tax or after-tax contributions by employees, depending on
the type of retirement program. After-tax employee contributions constitute
"investment in the Contract." All Contracts receive deferral of tax on the
inside build-up of earnings on invested Purchase Payments, until a distribution
occurs. See the Statement of Additional Information for special rules, including
those applicable to taxable, non-natural owners of Non-Qualified Contracts.
 
   
Transfers among investment options within a variable annuity contract generally
are not taxed at the time of such a transfer. However, in 1986 the Internal
Revenue Service (IRS) indicated that limitations might be imposed with respect
to either the number of investment options available within a contract, or the
frequency of transfers between investment options, or both, in order for the
contract to be treated as an annuity contract for federal income tax purposes.
If imposed, such limitations could be applied to qualified contracts as well as
nonqualified contracts, and VALIC can provide no assurance that such limitations
would not be imposed on a retroactive basis to contracts issued under this
prospectus. However, VALIC has no present indications that the IRS intends to
impose such limitations, or what the terms or scope of those limitations might
be.
    
 
Distributions are taxed differently depending on the program through which
Portfolio Director is offered and the previous tax characterization of the
contributions to which the distribution relates. Generally, the portion of a
distribution which is not considered a return of investment in the Contract is
subject to income tax. For annuity payments, investment in the contract is
recovered ratably over the expected payout period. Special recovery rules might
apply in certain situations.
 
   
Amounts subject to income tax may also incur excise or penalty taxes, under the
circumstances

described in the Statement of Additional Information. Generally, they would also
be subject to some form of federal income tax withholding unless rolled into
another tax-deferred vehicle. Required withholding will vary according to type
of program, type of payment and your tax status. In addition, amounts received
under all Contracts may be subject to state income tax withholding requirements.
 
                                                                              43

EFFECT OF TAX-DEFERRED ACCUMULATIONS
 
The chart below compares the results from
Premium Payments made to:
 
  - Portfolio Director Contract issued to a tax favored retirement program
    purchased with pre-tax premium payments;
 
  - A non-qualified Contract purchased with after-tax Premium Payments and;
 
  - Conventional savings vehicles such as savings accounts.
 
                        THE POWER OF TAX-DEFERRED GROWTH
                                    [CHART]
 
   
This hypothetical chart compares the results of (1) contributing $100 per month
to a conventional, non-tax deferred plan, (2) contributing $100 to a
nonqualified, tax-deferred annuity, and (3) contributing $100 per month ($138.89
since contributions are made before tax) to a qualified tax-deferred plan. The
chart assumes a 28% tax rate and an 8% fixed rate of return. Variable options
incur mortality and expense risk fee and administration and distribution fee
charges (1% - 1.25%) and may also incur administrative fees ($3.75 per quarter)
and surrender charges (5% of the lesser of all contributions received during the
last 60 months or the amount withdrawn). The dotted lines represent the amounts
remaining after withdrawal and payment of taxes and any surrender charge. An
additional 10% tax penalty may apply to withdrawals before age 59 1/2. This
information is for illustrative purposes only and is not a guarantee of future
return.
    
 
Unlike savings accounts, Premium Payments made to tax-favored retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax-favored retirement programs
ordinarily are not subject to income tax until withdrawn. As shown above,
investing in a tax-favored program increases the accumulation power of savings
over time. The more taxes saved and reinvested in the program, the more the
accumulation power effectively grows over the years.
 
To further illustrate the advantages of tax deferred savings using a 28% Federal
tax bracket, an annual fixed yield (BEFORE THE DEDUCTION OF ANY FEES OR CHARGES)
of 8% under a tax-favored retirement program in which tax savings were
reinvested has an equivalent after-tax annual fixed yield of 5.76% under a
conventional savings program. THE 8% YIELD ON THE TAX-FAVORED PROGRAM WILL BE
REDUCED BY THE IMPACT OF INCOME TAXES UPON WITHDRAWAL. The yield will vary
depending upon the timing of withdrawals. The previous chart represents (without
factoring in fees and charges) after-tax amounts that would be received.
 
By taking into account the current deferral of taxes, contributions to
tax-favored retirement programs increase the amount available for savings by
decreasing the relative current out-of-pocket cost (referring to the effect on
annual net take-home pay) of the investment. The chart below illustrates this
principle by comparing a pre-tax contribution to a tax-favored retirement plan
with an after-tax contribution to a conventional savings account:

</TABLE>
 
This chart assumes a 28% Federal income tax rate. The $700 which is paid toward
current Federal income taxes reduces the actual amount saved in the conventional
savings account to $1,800, while the full $2,500 is contributed to the
tax-favored program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,500, the contribution to a
tax-favored retirement program results in a current out-of-pocket expense of
$1,800 while the contribution to a conventional savings account requires the
full $2,500 out-of-pocket expense. The tax-favored retirement program
represented in this chart is a plan type, such as one under Section 403(b) of
the Code, which allows participants to exclude contributions within limits, from
gross income.

YEAR 2000
- --------------------------------------------------------------------------------
 
YEAR 2000 RISKS
 
   
Like other organizations and individuals around the world, VALIC could be
adversely affected if the computer systems used by VALIC, as well as by other
service providers over which VALIC may have no control, do not properly process
and calculate date-related information and data from and after January 1, 2000.
This is commonly referred to as the "Year 2000 Problem." VALIC is taking steps
that it believes are reasonably designed to address the Year 2000 Problem with
respect to the computer systems VALIC uses. The following are some of the
initiatives being taken by VALIC to deal with the Year 2000 Problem.
    
 
   
  - INTERNAL SYSTEMS. VALIC has developed a plan to deal with the Year 2000
    Problem. This plan includes the five steps that we believe are essential to
    Year 2000 readiness. The plan includes 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 caused by the Year 2000 Problem; (3) reprogram or
    replace systems that are not Year 2000 ready; (4) test systems to prove that
    they will work correctly into the Year 2000; and (5) return the systems to
    operations. As of December 31, 1998, we have substantially completed all
    steps with respect to our critical systems.
    
 
   
  - EXTERNAL SYSTEMS. VALIC has relationships with various third parties that
    must also be Year 2000 ready. Third parties are companies that provide
    certain services to VALIC. Third parties are different from internal systems
    in that VALIC has less, or no, control over their Year 2000 readiness. VALIC
    has developed a plan to review and try to lessen the Year 2000 risks of
    third parties. As of December 31, 1998, VALIC has substantially completed
    its review of third party Year 2000 risks. VALIC intends to test third party
    Year 2000 readiness throughout 1999.
    
 
   
  - CONTINGENCY PLANS. VALIC has begun contingency planning to reduce the risk
    associated with the Year 2000 Problem. The contingency plans for third party
    relationships include the following activities: (1) evaluate the
    consequences of any failures associated with the Year 2000 Problem; (2)
    determine the chance of a Year 2000-related failure for systems that have a
    high chance of failing; (3) develop an action plan to complete contingency
    plans for those systems that rank high in both impact of failure and chance
    of failure; and (4) complete any action plans.
    
 
   
VALIC expects to substantially complete all contingency planning activities by
April 30, 1999.
    
 
   
RISKS AND UNCERTAINTIES. Based on the above, VALIC believes that it will
experience, at most, isolated and minor disruptions of business systems on and
after January 1, 2000. These disruptions are not expected to have a material
effect on VALIC's operations or financial condition. However, it is impossible
to know exactly how the Year 2000 Problem will affect VALIC. In addition, third
party Year 2000 Problems may have a significant impact on VALIC.
    
 
   
Through December 1998, VALIC has incurred and expensed $26.7 million (pretax)
related to Year 2000 readiness, including $20.2 million incurred during 1998.
VALIC currently anticipates that it will incur future costs of $2.1 million for
additional internal staff, third party vendors, and other expenses to maintain
readiness and complete third party contingency plans.

                              GENERAL INFORMATION
 
   
     The Variable Annuity Life Insurance Company (the "Company") is a stock life
insurance company organized under the laws of the State of Texas and is engaged
primarily in the offering and issuance of fixed and variable retirement annuity
contracts and combinations thereof. The Company also is licensed to write life
insurance in all states (other than Connecticut) and the District of Columbia,
and annuities in all fifty states and the District of Columbia. The Company is
an indirectly wholly owned subsidiary of American General Corporation.
    
 
   
     On July 25, 1979, the Company established Separate Account A (the Separate
Account) in accordance with the Texas Insurance Code. The Separate Account is
registered with the Securities and Exchange Commission ("SEC") as a unit
investment trust under the Investment Company Act of 1940 (the "Act").
    
 
   
     Each Division of the Separate Account (except for AGSPC's International
Government Bond Fund, the American General Lifestyle Funds and the Vanguard
LifeStrategy Funds, each of which is a non-diversified Fund) invests in the
shares of a diversified, open-end, management-type investment company registered
under the Act, or a portfolio of a diversified, open-end, management investment
company registered under the Act. The Separate Account currently is made up of
53 Divisions.
    
 
   
MARKETING INFORMATION
    
 
     The Company has targeted organizations in specific market sectors as the
central focus of its marketing efforts for its Contracts. The Company has
utilized as its general marketing theme the concept that the Company is
"America's Retirement Plan Specialists." Specifically, the Company's marketing
thrust is aimed at individuals and groups associated with public and private,
primary and secondary schools, colleges and universities, healthcare
organizations, state and local governments and other organizations.
 
   
     This marketing concept has proven to be successful. In the aggregate,
premium deposits to the Company have grown from $37,000 in 1956 to more than
$3.7 billion as of December 31, 1998. The number of aggregate participant
accounts has increased from 155,000 accounts in 1980 to more than 1,954,190
accounts as of December 31, 1998. The number of employer groups which have
purchased Contracts has increased by 178 percent in the past ten years to more
than 26,392 as of December 31, 1998. As of December 31, 1998, the Company was
ranked in the top 1 percent of all U.S. life insurance companies with regard to
asset size. As of December 31, 1998 the Company's assets totaled more than $39
billion.
    
 
     The Company's growth can also be reviewed by examining each market segment
the Company targets.
 
   
     As of December 31, 1998, the Company was marketing Contracts in more than
10,218 public and private, primary and secondary schools with more than 494,584
participant accounts for employees in public and private schools nationwide.
From December 31, 1988 to December 31, 1998, the cash value of investments in
these Contracts has increased by 269 percent while the number of public and
private school groups in these Contracts increased 97 percent and the number of
participant accounts in these Contracts increased by 111 percent.
    
 
   
     The Company has also increased its marketing efforts to colleges and
universities. From December 31, 1988 to December 31, 1998, the number of
colleges and universities which allow the Company to market Contracts to its
faculty and staff members has increased 166 percent and for the same period the
number of participant accounts has increased 131 percent. For the same time
period cash values for participants have increased 306 percent. As of December
31, 1998, nearly 33 percent of United States colleges and universities allow the
Company to market Contracts to their faculty and staff members.
    
 
     The Company has utilized as the central focus in its marketing to college
and university faculty and staff members the theme that the Company is the
"Alternative of Choice."
 
   
     The Company has also had growth in the healthcare market segment. From
December 31, 1988 to December 31, 1998 Contract cash values have increased 802
percent. During the same period the number of healthcare groups that have
purchased these Contracts increased 274 percent and
    
 
                                        4
<PAGE>   561
 
   
the number of participant accounts increased 727 percent.
    
 
   
     The Company has also experienced growth in contracts sold to state and
local governmental groups. From December 31, 1988 to December 31, 1998, Contract
cash values for participants in these groups have increased 310 percent. For the
same period the number of participant accounts for individuals in these groups
in these Contracts increased 229 percent and the number of employer groups has
increased 303 percent.
    
 
   
     Additionally, many states operate, as an alternative to state administered
defined benefit retirement programs, Optional Retirement Plans (ORPs). A state
that sponsors an ORP will select one or more carriers to participate in the ORP.
The Company has been selected as one of the carriers permitted to market
Contracts to state employees who elect to participate in the ORP in 28 of the 31
states that sponsor ORPs as an alternative to a stated defined, benefit plan and
offers multiple carriers, as of December 31, 1998. From December 31, 1993 to
December 31, 1998, in these ORPs the number of participant accounts increased 81
percent and cash values increased 153 percent to nearly $2.7 billion.
    
 
     The Company may, from time to time, refer to American General Retirement
Services. American General Retirement Services is a financial reporting segment
of American General Corporation. The Company and American General Annuity
Insurance Company are the two insurance companies that constitute American
General Retirement Services.
 
     The Company may, from time to time, refer to a general investment strategy
known as indexing. Several of the Divisions employ this investment strategy. The
Company may compare the performance of these Divisions to the S&P 500 Index, S&P
MidCap 400 Index, Russell 2000 Index, Morgan Stanley Capital International
Europe, Australia, and Far East (EAFE) Index, or any other appropriate market
index. The indexes are not managed funds and have no identifiable investment
objectives.
 
     The Company may, from time to time, refer, individually or collectively, to
its package of retirement plan services. Collectively, this package of services
may be referred to as easy Retirement Plan(SM). Easy Retirement Planning
includes: (1) personal, face-to-face service from highly trained VALIC
Retirement Planning Specialists; (2) informative retirement-investment education
programs, seminars and materials; (3) specialized computer-aided services for
retirement planning and developing asset allocation strategies; (4) a wide
selection of innovative, market-responsive investment options; (5) advanced and
efficient administration of retirement accounts; and (6) a financially strong
and stable Company with which to do business.
 
     The Company may, from time to time, refer to the diversifying process of
asset allocation based on the Modern Portfolio Theory developed by Nobel
Prize-winning economist Harry Markowitz. The basic assumptions of Modern
Portfolio Theory are that the selection of individual investments has little
impact on portfolio performance, market timing strategies seldom work, markets
are efficient and selecting the suitable mix of asset classes is more important
when creating a long-term investment portfolio. Modern Portfolio Theory allows
an investor to determine an "efficient" or "optimized" portfolio that has
historically provided a higher return with the same risk or the same return with
lower risk.
 
   
     When presenting the asset allocation process the Company may outline the
process of personal and investment risk analysis including determining
individual risk tolerances and a discussion of the different types of investment
risk. The Company may classify investors into five categories based on their
personal risk tolerance and will quote various industry experts on which types
of investments are best suited to each of the five risk categories. The industry
experts quoted may include Ibbotson Associates, CDA Investment Technologies,
Lipper Analytical Services, Laffer-Cantos, Inc., The Variable Annuity Research &
Data Services ("VARDS") Report, Wilson Associates, Morningstar, Inc. and any
other expert which has been deemed by the Company to be appropriate. The Company
may also provide a historical overview of the performance of a variety of
investment market indexes and different asset categories, such as stocks, bonds,
cash equivalents, etc. The Company may also discuss investment volatility
(standard deviation) including the range of returns for different asset
categories and classes over different time horizons, and the correlation between
the returns of different asset categories and classes. The Company may also
discuss the basis of portfolio optimization including
    
 
                                        5
<PAGE>   562
 
the required inputs and the construction of efficient portfolios using
sophisticated computer-based techniques. Finally, the Company may describe
various investment strategies and methods of implementation such as the use of
index funds vs. actively managed funds, the use of dollar cost averaging
techniques, the tax status of contributions, and the periodic rebalancing of
diversified portfolios.
 
     The Company, in its marketing efforts to each of the market segments, may
from time to time design sales literature and material specifically for that
market segment, e.g., the healthcare segment. This sales literature and material
may also be specific to a certain group. For example, sales literature and
material may be designed for a specific hospital. The sales literature and
material would address specifically the group's contract and retirement plan.
 
     The Company, in its marketing efforts, may also refer to the following
investment advisers referenced in the Prospectus.
 
   
     The Company may, from time-to-time, refer to American Century Investment
Management, Inc. (ACIM) as investment adviser to the American Century Ultra Fund
(underlying Division Thirty-One). The nation's fourth-largest family of direct-
marketed, no-load mutual funds, American Century also represents the
15th-largest family of funds overall. American Century offers more than 70 no-
load funds and manages assets for more than 2 million investors. American
Century, as of Dec. 31, 1998, had more than $70 billion in assets under
management.
    
 
   
     The Company may, from time to time, refer to The Dreyfus Corporation as the
investment adviser for the Dreyfus Small Cap Portfolio (underlying Division
Eighteen). The Dreyfus Corporation has been helping Americans invest for their
future with quality mutual funds, for more than four decades. As of December 31,
1998, the firm had approximately $117 billion in assets under management.
    
 
   
     The Company may, from time-to-time, refer to Evergreen Asset Management
Corp. (Evergreen Asset) as investment adviser to Evergreen Growth and Income
Fund (underlying Division 56) and Evergreen Small Cap Value Fund (underlying
Division 55). Evergreen Asset is a wholly-owned subsidiary of First Union
Corporation (First Union). Evergreen Asset, with its predecessors, has served as
investment adviser to certain Evergreen mutual funds since 1971 and currently
manages over $10 billion in assets.
    
 
   
     The Company may, from time-to-time, refer to the Capital Management Group
of First Union National Bank (FUNB) as investment adviser to Evergreen Value

     Bankers Trust Company, sub-adviser to Divisions 4, 10 and 14, and one of
two sub-advisers to Division 36, is a wholly owned subsidiary of Bankers Trust
Corporation. On November 30, 1998, Bankers Trust Corporation entered into an
Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
Corporation and all of its subsidiaries would merge with and into a subsidiary
of Deutsche Bank AG. Deutsche Bank AG is a major global banking institution that
is engaged in a wide range of financial services, including retail and
commercial banking, investment banking and insurance. The merger is contingent
upon various regulatory approvals. On April 20, 1999, the AGSPC Fund's Board of
Directors approved a new investment sub-advisory agreement with Bankers Trust
Company, subject to shareholder approval and the Trustees of AGSPC 3 also
approved a new investment sub-advisory agreement with Bankers Trust Company,
which is not subject to shareholder approval. If the merger is approved and
completed, Deutsche Bank AG, as the Sub-Adviser's new parent company, will
control the operations of the Sub-Adviser. Bankers Trust believes that, under
this new arrangement, the services provided to the Fund will be maintained at
their current level.
    
 
   
     On March 11, 1999, Bankers Trust announced that it had reached an agreement
with the United States Attorney's Office in the Southern District of New York to
resolve an investigation concerning inappropriate transfers of unclaimed funds
and related recordkeeping problems that occurred between 1994 and early 1996.
Pursuant to its agreement with the U.S. Attorney's Office, Bankers Trust pleaded
guilty to misstating entries in the bank's books and records and agreed to pay a
$60 million fine to federal authorities. Separately, Bankers Trust agreed to pay
a $3.5 million fine to the State of New York. The events leading up to the
guilty pleas did not arise out of the investment
    
                                        8
<PAGE>   565
 
   
advisory or mutual fund management activities of Bankers Trust or its
affiliates.
    
 
   
     As a result of the plea, absent an order from the SEC, Bankers Trust would
not be able to continue to provide investment advisory services to the Fund. The
SEC has granted a temporary order to permit Bankers Trust and its affiliates to
continue to provide investment advisory services to registered investment
companies. There is no assurance that the SEC will grant a permanent order.
    
 
     The Company may, from time to time, refer in advertisements or sales
materials to certain milestones which are intended to emphasize the Company's
growth and development in assets, groups and various market segments. The
Company may also refer to other versions of Portfolio Director Plus in
advertisements or sales material. The Company may refer to certain innovative
aspects of its products such as having a variety of publicly available mutual
funds as Variable Account Options. Additionally the Company may refer from time
to time in advertisements or sales materials to marketing strategies it utilizes
to promote the Company's business objectives. Further, the Company may refer
from time to time in advertisements or sales materials to certain value-added
services it provides to its groups, Contract Owners and Participants.
 
     The Company may, from time to time, refer in its advertisements to Schwab
Personal Choice Retirement Accounts ("PCRA"). The PCRA is a self-directed
brokerage account that may be used by VALIC Participants to directly invest in
publicly available mutual funds. PCRA is marketed through the VALIC Investment
Services Company.
 
     The Company may, from time to time, compare the performance of the mutual
funds that serve as the investment vehicles for Portfolio Director Plus to the
performance of certain market indices. These market indices are described in the
"Performance Information" Section of this Statement of Additional Information.
 
ENDORSEMENTS AND
PUBLISHED RATINGS
 
     From time to time, in advertisements or in reports to Contract Owners, the
Company may refer to its endorsements. Endorsements are often in the form of a
list of organizations, individuals or other parties which recommend the Company
or the Contracts. The endorser's name will be used only with the endorser's
consent. It should be noted that the list of endorsements may change from time
to time.
 
     Also from time to time, the rating of the Company as an insurance company
by A. M. Best may be referred to in advertisements or in reports to Contract
Owners. Each year the A. M. Best Company reviews the financial status of
thousands of insurers, culminating in the assignment of Best's Ratings. These
ratings reflect their current opinion of the relative financial strength and
operating performance of an insurance company in comparison to the norms of the
life/health insurance industry. Best's Ratings range from A++ to F.
 
     In addition, the claims-paying ability of the Company as measured by the
Standard and Poor's Ratings Group may be referred to in advertisements or in
reports to Contract Owners. A Standard and Poor's insurance claims-paying
ability rating is an assessment of an operating insurance company's financial
capacity to meet the obligations of its insurance policies in accordance with
their terms. Standard and Poor's ratings range from AAA to D.
 
     Further, from time to time the Company may refer to Moody's Investor's
Service's rating of the Company. Moody's Investor's Service's financial strength
ratings indicate an insurance company's ability to discharge senior policyholder
obligations and claims and are based on an analysis of the insurance company and
its relationship to its parent, subsidiaries and affiliates. Moody's Investor's
Service's ratings range from Aaa to C.
 
     The Company may additionally refer to its Duff & Phelp's rating. A Duff &
Phelp's rating is an assessment of a company's insurance claims paying ability.
Duff & Phelp's ratings range from AAA to CCC.
 
     Ratings relate to the claims paying ability of the Company's General
Account and not the investment characteristics of the Separate Account.
 
     The Company may from time to time, refer to Lipper Analytical Services
Incorporated ("Lipper"), Morningstar, Inc. ("Morningstar") and CDA/Wiesenberger
Investment Companies (CDA/Wiesenberger) when discussing the performance of its
Divisions. Lipper, Morningstar and CDA/Wiesenberger are leading publishers of
statistical data about the investment company industry in the United States.

     Additionally, the Company may compare the performance of the Divisions to
categories published by Lipper and Morningstar. Morningstar has not, however,
ranked the Neuberger Berman Guardian Trust. The published categories which may
be utilized in comparison with the performance of the Divisions include the
Morningstar Growth and Income Mutual Fund Category, Morningstar Aggressive
Growth Mutual Fund Category, Morningstar Growth Mutual Fund Category,
Morningstar International Stock Mutual Fund Category, Lipper Growth and Income
Mutual Fund Category, Lipper Small Company Growth Mutual Fund Category, Lipper
Growth Mutual Fund Category and Lipper International Mutual Fund Category.

by the Company relevant to the performance of the Company's Divisions.
    
 
   
     The Company may, from time to time, refer to the VARDS Report. The VARDS
Report offers monthly analysis of the variable annuity industry, including
marketing and performance information.
    
 
     Finally the Company will utilize as a comparative measure for the
performance of its Funds the Consumer Price Index ("CPI"). The CPI is a measure
of change in consumer prices, as determined in a monthly survey of the U.S.
Bureau of Labor Statistics. Housing costs, transportation, food, electricity,
changes in taxes and labor costs are among the CPI components. The CPI provides
a tool for determining the impact of inflation on an individual's purchasing
power.
 
TYPES OF VARIABLE ANNUITY
CONTRACTS
 
     Flexible payment deferred annuity Contracts are offered in connection with
the prospectus to which this Statement of Additional Information relates.
 
     Under flexible payment Contracts, Purchase Payments generally are made
until retirement age is reached. However, no Purchase Payments are required to
be made after the first payment. Purchase Payments are subject to any minimum
payment requirements under the Contract.
 
     Under deferred annuity contracts, Purchase Payments are invested and
accumulate on a fixed or variable basis until the date the Contract Owner
selects to commence annuity payments.
 
     The Contracts are non-participating and will not share in any of the
profits of the Company.
 
FEDERAL TAX MATTERS
 
     This Section summarizes the major tax consequences of contributions,
payments, and withdrawals under Portfolio Director Plus, during life and at
death.
 
     It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if Purchase Payments under the contract are invested in
publicly available mutual funds. If investment in publicly available mutual
funds were to cause the tax deferral provisions described below for these
specific types of contracts not to apply, you would be currently taxed on
transfers, redemptions, purchase payments and dividend and capital gains
distributions.
 
     In addition, it is also the opinion of VALIC and its tax counsel that, for
each other type of Qualified Contract, an independent exemption provides tax
deferral regardless of ownership of the Mutual Fund shares.
 
     For Non-Qualified Contracts, not all Variable Account Options are available
within your contract. Variable Account Options that are invested in Mutual Funds
available to the general public outside of annuity contracts or life insurance
contracts will be offered only to non-natural persons pursuant to the meaning of
Section 72 of the Code. In that case, investment earnings on contributions to
Non-Qualified Contracts generally will be taxed currently to the owner, and the
contracts will not be treated as annuities for federal income tax purposes.
 
TAX CONSEQUENCES OF PURCHASE PAYMENTS
 
   
     403(b) Annuities. Purchase Payments made by Section 501(c)(3) tax-exempt
organizations and public educational institutions toward Contracts for their
employees are excludable from the gross income of employees, to the extent
aggregate Purchase Payments do not exceed several competing tax law limitations
on contributions. This gross income exclusion applies both to employer
contributions and to your voluntary and nonelective salary reduction
contributions.
    
                                       10
<PAGE>   567
     Your voluntary salary reduction contributions are generally limited to
$10,000 ($9,500 before 1998), although additional, "catch-up" contributions are
permitted under certain circumstances. Combined employer and salary reduction
contributions are generally limited to the smallest of $30,000; approximately
25% of salary; or an exclusion allowance which takes into account a number of
factors. In addition, after 1988 employer contributions for highly compensated
employees may be further limited by applicable nondiscrimination rules.
 
     401(a) and 403(a) Qualified Plans. Purchase Payments made by an employer
(or a self-employed individual) under a qualified pension, profit-sharing or
annuity plan are excluded from the gross income of the employee. Purchase
Payments made by an employee generally are made on an after-tax basis, unless
eligible for pre-tax treatment by reason of Sections 401(k) or 414(h).
 
   
     408(b) Individual Retirement Annuities ("408(b) IRAs"). Annual
tax-deductible contributions for 408(b) IRA Contracts are limited to the lesser
of $2,000 or 100% of compensation, and generally fully deductible only by
individuals who:
    
 
 (i)  are not active participants in another retirement plan, and are not
      married;
 
 (ii) are not active participants in another retirement plan, are married, but
      either (a) the spouse is not an active participant in another retirement
      plan, or (b) the spouse is an active participant, but the couple's
      adjusted gross income does not exceed $150,000.
 
   
(iii) are active participants in another retirement plan, are unmarried, and
      have adjusted gross income of $31,000 or less ($30,000 for 1998, $25,000
      or less prior to 1998; adjusted upward for inflation after 1998); or
    
 
   
(iv)  are active participants in another retirement plan, are married, and have
      adjusted gross income of $51,000 or less ($50,000 for 1998, $40,000 or 
      less prior to 1998; adjusted upward for inflation after 1998).
    
 
     Active participants in other retirement plans whose adjusted gross income
exceeds the limits in (ii), (iii) or (iv) by less than $10,000 are entitled to
make deductible 408(b) IRA contributions in proportionately reduced amounts. If
a 408(b) IRA is established for a nonworking spouse who has no compensation, the
annual tax-deductible Purchase Payments for both spouses' Contracts cannot
exceed the lesser of $4,000 or 100% of the working spouse's earned income, and
no more than $2,000 may be contributed to either spouse's IRA for any year.
 
     You may be eligible to make nondeductible IRA contributions of an amount
equal to the excess of:
 
 (i) the lesser of $2,000 ($4,000 for you and your spouse's IRA) or 100% of
     compensation, over
 
(ii) your applicable IRA deduction limit.
 
     You may also make contributions of eligible rollover amounts from other
qualified plans and contracts. See Tax-Free Rollovers, Transfers and Exchanges.
 
     408A "Roth" Individual Retirement Annuities ("408A "Roth" IRAs"). After
1997, annual nondeductible contributions for 408A "Roth" IRA Contracts are
limited to the lesser of $2,000 or 100% of compensation, and may be made only by
individuals who:
 
 (i) are unmarried and have adjusted gross income of $95,000 or less; or
 
(ii) are married and filing jointly, and have adjusted gross income of $150,000
     or less.
 
The available nondeductible 408A "Roth" IRA contribution is reduced
proportionately to zero where adjusted gross income exceeds the limit in (i) by
$15,000 or less, or the limit in (ii) by $10,000 or less. Similarly, individuals
who are married and filing separately and whose adjusted gross income is less
than $15,000 may make a contribution to a Roth IRA of a portion of the otherwise
applicable $2,000 or 100% of compensation limit.
 
     All contributions to 408(b) IRAs, traditional nondeductible IRAs and 408A
"Roth" IRAs must be aggregated for purposes of the $2,000 annual contribution
limit.
 
     457 Plans. A unit of a state or local government may establish a deferred
compensation program for individuals who perform services for the government
unit. In addition, a non-governmental tax-exempt employer may establish an
eligible deferred compensation program for individuals who: (i) perform services
for the employer, and (ii) belong to a select group of management or highly
compensated employees and/or independent contractors.

                                       11
<PAGE>   568
 
   
     This type of program allows eligible individuals to defer the receipt of
compensation (and taxes thereon) otherwise presently payable to them. If the
program is an eligible deferred compensation plan (an "EDCP"), in 1999 you may
contribute (and defer tax on) the lesser of $8,000 (indexed for inflation) or
33 1/3% of your "includible" compensation (compensation from the employer
currently includible in taxable income). Additionally, catch-up deferrals are
permitted in the final three years before the year you reach normal retirement
age.
    
 
   
     The employer uses deferred amounts to purchase the Contracts offered by
this prospectus. For plans maintained by a unit of a state or local government,
the Contract is generally held for the exclusive benefit of plan participants,
although certain Contracts may remain subject to the claims of the employer's
general creditors until 1999. The employee has no present rights to any vested
interest in the Contract and is entitled to payment only in accordance with the
EDCP provisions.
    
 
     Simplified Employee Pension Plan ("SEP"). Employer contributions under a
SEP are made to a separate individual retirement account or annuity established
for each participating employee, and generally must be made at a rate
representing a uniform percent of participating employees' compensation.
Employer contributions are excludable from employees' taxable income, and after
1993 cannot exceed the lesser of $30,000 or 15% of your compensation.
 
     Through 1996, employees of certain small employers (other than tax-exempt
organizations) were permitted to establish plans allowing employees to
contribute pretax, on a salary reduction basis, to the SEP. In 1998 and 1999,
these salary reductions may not exceed $10,000 per year. This limit is indexed
and may be increased in future years. Such plans if established by December 31,
1996, may still allow employees to make these contributions.
 
     SIMPLE IRA. Employer and employee contributions under a SIMPLE Retirement
Account Plan are made to a separate individual retirement account or annuity for
each employee. Employee salary reduction contributions cannot exceed $6,000 in
any year. Employer contributions can be a matching or a nonelective contribution
of a percentage as specified in the Code. Only employers with 100 or fewer
employees can maintain a SIMPLE IRA plan, which must also be the only plan the
employer maintains.
 
     Non-Qualified Contracts. Purchase Payments made under Non-Qualified
Contracts are neither excludible from the gross income of the Contract Owner nor
deductible for tax purposes. However, any increase in the Purchase Unit Value of
a Non-Qualified Contract resulting from the investment performance of VALIC
Separate Account A is not taxable to the Contract Owner until received by him.
Contract Owners that are not natural persons, however, are currently taxable on
any increase in the Purchase Unit Value attributable to Purchase Payments made
after February 28, 1986 to such Contracts.
 
TAX CONSEQUENCES OF DISTRIBUTIONS
 
     403(b) Annuities. Voluntary salary reduction amounts accumulated after
December 31, 1988, and earnings on voluntary contributions before and after that
date, may not be distributed before one of the following:
 
(1) attainment of age 59 1/2;
 
(2) separation from service;
 
(3) death;
 
(4) disability, or
 
(5) hardship (hardship distributions are limited to salary reduction
    contributions only, exclusive of earnings thereon).
 
     Similar restrictions will apply to all amounts transferred from a section
403(b)(7) custodial account other than rollover contributions.
 
     Distributions are taxed as ordinary income to the recipient in accordance
with Section 72.
 
     401(a) and 403(a) Qualified Plans. Distributions from Contracts purchased
under qualified plans are taxable as ordinary income, except to the extent
allocable to an employee's after-tax contributions (investment in the Contract).
If you or your Beneficiary receive a "lump sum distribution" (legally defined
term), the taxable portion may be subject to special 5-year or 10-year income
averaging treatment. Five-year forward averaging is unavailable for
distributions occurring after December 31, 1999. Ten-year income averaging uses
tax rates in effect for 1986, allows 20% capital gains treatment for the taxable
portion of a lump sum distribution attributable to years of service before 1974,
and is available if you were 50 or older on January 1, 1986.
                                       12
<PAGE>   569
 
     408(b) IRA, SEPs and SIMPLE IRAs. Distributions are generally taxed as
ordinary income to the recipient. Rollovers from an IRA to a Roth IRA, and
conversions of an IRA to a Roth IRA, where permitted, are generally taxable in
the year of the rollover or conversion. Such rollovers or conversions completed
in 1998 are generally eligible for pro-rata federal income taxation over four
years. Individuals with adjusted gross income over $100,000 are generally
ineligible for such conversions, regardless of marital status, as are married
individuals who file separately.
 
     408A "Roth" IRAs. "Qualified" distributions upon attainment of age 59 1/2,
upon death or disability or for first-time homebuyer expenses are tax-free as
long as five or more years have passed since the first contribution to
taxpayer's first 408A "Roth" IRA. Qualified distributions may be subject to
state income tax in some states. Other distributions are generally taxable to
the extent that the distribution exceeds purchase payments.
 
     457 Plans. Amounts received from an EDCP are includible in gross income for
the taxable year in which they are paid or otherwise made available to the
recipient.
 
     Non-Qualified Contracts. Partial redemptions from a Non-Qualified Contract
purchased after August 13, 1982 (or allocated to post-August 13, 1982 Purchase
Payments under a pre-existing Contract), generally are taxed as ordinary income
to the extent of the accumulated income or gain under the Contract if they are
not received as an annuity. Partial redemptions from a Non-Qualified Contract
purchased before August 14, 1982 are taxed only after the Contract Owner has
received all of his pre-August 14, 1982 investment in the Contract. The amount
received in a complete redemption of a Non-Qualified Contract (regardless of the
date of purchase) will be taxed as ordinary income to the extent that it exceeds
the Contract Owner's investment in the Contract. Two or more Contracts purchased
from VALIC (or an affiliated company) by a Contract Owner within the same
calendar year, after October 21, 1998, are treated as a single Contract for
purposes of measuring the income on a partial redemption or complete surrender.
 
     When payments are received as an annuity, the Contract Owner's investment
in the Contract is treated as received ratably and excluded ratably from gross
income as a tax-free return of capital, over the expected payment period of the
annuity. Individuals who begin receiving annuity payments on or after January 1,
1987 can exclude from income only their unrecovered investment in the Contract.
Upon death prior to recovering tax-free their entire investment in the Contract,
such individuals generally are entitled to deduct the unrecovered amount on
their final tax return.
 
SPECIAL TAX CONSEQUENCES -- EARLY
DISTRIBUTION
 
     403(b) Annuities, 401(a) and 403(a) Qualified Plans, 408(b) IRAs, SEPs and
SIMPLE IRAs. Taxable distributions received before the recipient attains age
59 1/2 generally are subject to a 10% penalty tax in addition to regular income
tax. Distributions on account of the following generally are excepted from this
penalty tax:
 
(1) death;
 
(2) disability;
 
(3) separation from service after a participant reaches age 55 (only applies to
    403(b), 401(a), 403(a));
 
(4) separation from service at any age if the distribution is in the form of
    substantially equal periodic payments over the life (or life expectancy) of
    the Participant (or the Participant and Beneficiary), and
 
(5) distributions which do not exceed the employee's tax deductible medical
    expenses for the taxable year of receipt.
 
Separation from service is not required for distributions from an IRA, SEP or
SIMPLE IRA under #4 above. Certain distributions from a SIMPLE IRA within two
years after first participating in the plan may be subject to a 25% penalty,
rather than a 10% penalty.
 
Currently, distributions from 408(b) IRAs on account of the following additional
reasons are also excepted from this penalty tax:
 
(6) distributions up to $10,000 (in the aggregate) to cover costs of acquiring,
    constructing or reconstructing the residence of a first-time homebuyer, and
 
   
(7) distributions to cover certain costs of higher education: tuition, fees,
    books, supplies and equipment for the IRA owner, a spouse, child or
    grandchild, and
    
 
                                       13
<PAGE>   570
 
(8) distributions to cover certain medical care or long term care insurance
    premiums, for individuals who have received federal or state unemployment
    compensation for 12 consecutive months.
 
     408A "Roth" IRAs. Distributions, other than "qualified" distributions where
the five-year holding rule is met, are generally subject to the same 10% penalty
tax as other IRAs. Distributions of rollover or conversion contributions from an
IRA which are not qualified distributions, may be subject to additional penalty
taxes.
 
     457 Plans. Distributions generally may be made under an EDCP prior to
separation from service only for unforeseeable emergencies, or for amounts under
$5,000 for inactive Participants, and are includible in the recipient's gross
income in the year paid.
 
     Non-Qualified Contracts. A 10% penalty tax applies to the taxable portion
of a distribution received before age 59 1/2 under a Non-Qualified Contract,
unless the distribution is:
 
(1) to a Beneficiary on or after the Contract Owner's death;
 
(2) upon the Contract Owner's disability;
 
(3) part of a series of substantially equal annuity payments for the life or
    life expectancy of the Contract Owner, or the lives or joint life expectancy
    of the Contract Owner and Beneficiary;
 
(4) made under an immediate annuity contract, or
 
(5) allocable to Purchase Payments made before August 14, 1982.
 
SPECIAL TAX CONSEQUENCES -- REQUIRED
DISTRIBUTIONS
 
     403(b) Annuities. Generally, minimum required distributions must commence
no later than April 1 of the calendar year following the later of the calendar
year in which the Participant attains age 70 1/2 or the calendar year in which
the Participant retires. Required distributions must be made over a period that
does not exceed the life or life expectancies of the Participant (or lives or
joint life expectancies of the Participant and Beneficiary). The minimum amount
payable can be determined several different ways. A penalty tax of 50% is
imposed on the amount by which the minimum required distribution in any year
exceeds the amount actually distributed in that year.
 
     Amounts accumulated under a Contract on December 31, 1986 may be paid in a
manner that meets the above rule or, alternatively:
 
(i)  must begin to be paid when Participant attains age 75; and
 
(ii) the present value of payments expected to be made over the life of the
     Participant, (under the option chosen) must exceed 50% of the present value
     of all payments expected to be made (the "50% rule").
 
The 50% rule will not apply if a Participant's spouse is the joint annuitant.
Notwithstanding these pre-January 1, 1987 rules the entire contract balance must
meet the minimum distribution incidental benefit requirement of Section
403(b)(10).
 
     At the Participant's death before payout has begun, Contract amounts
generally either must be paid to the Beneficiary within 5 years, or must begin
within 1 year of death and be paid over the life or life expectancy of the
Beneficiary. If death occurs after commencement of (but before full) payout,
distributions generally must continue at least as rapidly as under the method
elected by the Participant and in effect at the time of death.
 
     A participant generally may aggregate his or her 403(b) contracts and
accounts for purposes of satisfying these requirements, and withdraw the
required distribution in any combination from such contracts or accounts, unless
the plan, contract, or account otherwise provides.
 
     401(a) and 403(a) Qualified Plans. Minimum distribution requirements for
Qualified Plans are generally the same as described for 403(b) Annuities, except
that there is no exception for pre-1987 amounts, and multiple plans may not be
aggregated to satisfy the requirement.
 
     408(b) IRAs, SEPs and SIMPLE IRAs. Minimum distribution requirements are
generally the same as described above for 403(b) Annuities, except that:
 
(1) there is no exception for pre-1987 amounts; and
 
(2) there is no available postponement, past April 1 of the calendar year
    following the calendar year in which age 70 1/2 is attained.
 
     A participant generally may aggregate his or her IRAs for purposes of
satisfying these require-
 
                                       14
<PAGE>   571
 
ments, and withdraw the required distribution in any combination from such
contracts or accounts, unless the contract or account otherwise provides.
 
     408A "Roth" IRAs. Minimum distribution requirements generally applicable to
403(b) Annuities, 401(a) and 403(a) Qualified Plans, 408(b) IRAs, SEPs and 457
Plans do not apply to 408A "Roth" IRAs during the owner's lifetime, but
generally do apply at the owner's death.
 
   
     A participant generally may aggregate his or her Roth IRAs inherited from
the same decedent for purposes of satisfying these requirements, and withdraw
the required distribution in any combination from such contracts or accounts,
unless the contract or account otherwise provides.
    
 
     457 Plans. Beginning January 1, 1989, the minimum distribution requirements
for EDCP's are generally the same as described above for 403(b) Annuities except
that there is no exception for pre-1987 amounts, and multiple plans may not be
aggregated to satisfy the requirement.
 
     Non-Qualified Contracts. Non-Qualified Contracts do not require
commencement of distributions at any particular time during the Owner's
lifetime, provided that the Owner is a natural person, and generally do not
limit the duration of annuity payments.
 
     At the Participant's death before payout has begun, Contract amounts
generally either must be paid to the Beneficiary within 5 years, or must begin
within 1 year of death and be paid over the life or life expectancy of the
Beneficiary. If death occurs after commencement of (but before full) payout,
distributions generally must continue at least as rapidly as under the method
elected by the Participant at the time of death.
 
TAX-FREE ROLLOVERS, TRANSFERS AND EXCHANGES
 
     403(b) Annuities. Tax free transfers between 403(b) annuity contracts
and/or 403(b)(7) custodial accounts, and tax-free rollovers from 403(b) programs
to 408(b) IRAs or other 403(b) programs, are permitted under certain
circumstances.
 
     401(a) and 403(a) Qualified Plans. The taxable portion of certain
distributions may be transferred in a tax-free rollover to a 408(b) individual
retirement account or annuity, or to another such plan.
 
   
     408(b) IRAs. Funds may be transferred tax-free to a 408(b) IRA Contract in
a tax-free rollover, from a 403(b) Annuity, or 401(a) or 403(a) Qualified Plan,
under certain conditions. These amounts may subsequently be rolled over on a
tax-free basis to another such plan or 403(b) Annuity Contract from this
"conduit" IRA. In addition, tax-free rollovers may be made from one 408(b) IRA
(other than a Roth IRA) to another provided that no more than one such rollover
is made during any twelve-month period.
    
 
     408A "Roth" IRAs. Funds may be transferred tax-free from one 408A "Roth"
IRA to another. Funds in a 408(b) IRA may be rolled in a taxable transaction to
a 408A "Roth" IRA by individuals who:
 
 (i) have adjusted gross income of $100,000 or less, whether single or married
     filing jointly;
 
(ii) are not married filing separately.
 
   
     Special, complicated rules governing holding periods, avoidance of the 10%
penalty tax and ratable recognition of 1998 income also apply to rollovers from
408(b) IRAs to 408A "Roth" IRAs, and may be subject to further modification by
Congress. You should consult your tax advisor regarding the application of these
rules.
    
 
     408(p) SIMPLE IRAs. Funds may generally be rolled over tax free from a
SIMPLE IRA to a 408(b) IRA. However, during the two-year period beginning on the
date you first participate in any SIMPLE IRA plan of your employer, SIMPLE IRA
funds may only be rolled to another SIMPLE IRA.
 
     457 Plans. Tax-free transfer of EDCP amounts are permitted only to another
EDCP.
 
     Non-Qualified Contracts. Certain of the Non-Qualified single payment
deferred annuity Contracts permit the Contract Owner to exchange the Contract
for a new deferred annuity contract prior to the commencement of annuity
payments. The exchange of one annuity contract for another is a tax-free
transaction under Section 1035, but is reportable to the IRS.
 
EXCHANGE PRIVILEGE
 
     In the prospectus we described generally how under certain conditions we
will allow you to exchange from other fixed and/or variable contracts
 
                                       15
<PAGE>   572
 
we issue (other contracts) to Portfolio Director Plus. These other contracts are
listed in the prospectus. A more detailed comparison of the features, charges
and restrictions between each of these listed other contracts and Portfolio
Director Plus is provided below.
 
EXCHANGES FROM PORTFOLIO DIRECTOR
 
  Sales/Surrender Charges
 
     Portfolio Director and Portfolio Director Plus have the same provisions for
imposing surrender charges upon total or partial surrenders. Portfolio Director
and Portfolio Director Plus have the same provisions where surrender charges are
not imposed. For purposes of satisfying the fifteen-year and five-year holding
requirements described in "Surrender Charge" in the prospectus, Portfolio
Director Plus will be deemed to have been issued on the same date as Portfolio
Director. Purchase Payments exchanged into Portfolio Director Plus will be
treated as Purchase Payments under Portfolio Director Plus for purposes of
calculating the surrender charge. Exchanged payments will be deemed to have been
made under Portfolio Director Plus on the date they were made to Portfolio
Director for purposes of calculating the surrender charge under Portfolio
Director Plus.
 
  Other Charges
 
     Portfolio Director and Portfolio Director Plus have the same provisions for
imposing the quarterly account maintenance fee.
 
     Portfolio Director and Portfolio Director Plus impose an additional daily
charge with an annualized rate of 0.75% to 1.25% (or lower amounts during the
Purchase Period for different series of Portfolio Director Plus), depending upon
the Variable Account Option selected, if any, on the daily net asset value of
VALIC Separate Account A. This charge is to cover expenses not covered by the
account maintenance fee and to compensate the Company for assuming mortality and
expense risks and administration expenses. Under Portfolio Director Plus the
Company will reimburse to certain Divisions any fees it receives from a Mutual
Fund for providing the Mutual Fund administrative and shareholder services.
 
  Investment Options
 
   
     Under Portfolio Director, sixteen divisions of VALIC Separate Account A are
available, thirteen of which invest in different investment portfolios of AGSPC
and three divisions of which invest in other mutual fund portfolios. These
mutual fund portfolios are managed either by the Company, The Dreyfus
Corporation or Templeton Investment Counsel Inc. for advisory fees at annual
rates ranging from .28% to .90% of each portfolio's or mutual fund's average
daily net assets. Two fixed investment options are also available.
    
 
     Under Portfolio Director Plus, fifty-three divisions of VALIC Separate
Account A are available, thirteen of which invest in different investment
portfolios of AGSPC, eighteen of which invest in different investment portfolios
of American General Series Portfolio Company 3 ("AGSPC 3") and twenty-two of
which invest in other mutual fund portfolios. These mutual fund portfolios are
managed either by the Company or other investment managers for advisory fees
ranging from 0.01% to 1.00% of each portfolio's or mutual fund's average daily
net assets. Two fixed investment options are also available.
 
  Annuity Options
 
     Portfolio Director and Portfolio Director Plus provide the same annuity
options.
 
EXCHANGES FROM PORTFOLIO DIRECTOR 2
 
  Sales/Surrender Charges
 
     Portfolio Director 2 and Portfolio Director Plus have the same provisions
for imposing surrender charges upon total or partial surrenders. Portfolio
Director 2 and Portfolio Director Plus have the same provisions where surrender
charges are not imposed. For purposes of satisfying the fifteen-year and
five-year holding requirements described in "Surrender Charge" in the
prospectus, Portfolio Director Plus will be deemed to have been issued on the
same date as Portfolio Director 2. Purchase Payments exchanged into Portfolio
Director Plus will be treated as Purchase Payments under Portfolio Director Plus
for purposes of calculating the surrender charge. Exchanged payments will be
deemed to have been made under Portfolio Director Plus on the date they were
made to Portfolio Director 2 for purposes of calculating the surrender charge
under Portfolio Director Plus.
 
                                       16
<PAGE>   573
 
  Other Charges
 
     Portfolio Director 2 and Portfolio Director Plus have the same provisions
for imposing the quarterly account maintenance fee.
 
     Portfolio Director 2 and Portfolio Director Plus impose an additional daily
charge with an annualized rate of 0.75% to 1.25% (or lower amounts during the
Purchase Period for different series of Portfolio Director 2 and Portfolio
Director Plus), depending upon the Variable Account Option selected, if any, on
the daily net asset value of VALIC Separate Account A. This charge is to cover
expenses not covered by the account maintenance fee and to compensate the
Company for assuming mortality and expense risks and administration expenses.
Under Portfolio Director Plus the Company will reimburse to certain Divisions
any fees it receives from a Mutual Fund for providing the Mutual Fund
administrative and shareholder services.
 
  Investment Options
 
     Under Portfolio Director 2, eighteen divisions of VALIC Separate Account A
are available, six of which invest in a different portfolio of AGSPC and twelve
divisions of which invest in other publicly available mutual fund portfolios.
These mutual fund portfolios are managed either by the Company or other
investment managers for advisory fees ranging from 0.01% to 1.00% of each
portfolio's or mutual fund's average daily net assets. Two fixed investment
options are also available.
 
     Under Portfolio Director Plus, fifty-three divisions of VALIC Separate
Account A are available, thirteen of which invest in different investment
portfolios of AGSPC, eighteen of which invest in different investment portfolios
of AGSPC 3 and twenty-two of which invest in other mutual fund portfolios. These
mutual fund portfolios are managed either by the Company or other investment
managers for advisory fees ranging from 0.01% to 1.00% of each portfolio's or
mutual fund's average daily net assets. Two fixed investment options are also
available.
 
  Annuity Options
 
     Portfolio Director, Portfolio Director 2 and Portfolio Director Plus
provide the same annuity options.
 
EXCHANGES FROM INDEPENDENCE PLUS CONTRACTS
 
     Sales/Surrender Charges. Under an Independence Plus Contract, no sales
charge is deducted at the time a Purchase Payment is made, but a surrender
charge may be imposed on partial or total surrenders. The surrender charge may
not exceed 5% of any Purchase Payments withdrawn within five years of the date
such Purchase Payments were made. The most recent Purchase Payments are deemed
to be withdrawn first. Up to 10% of the Account Value may be surrendered in a
Participant Year without any surrender charge being imposed. Portfolio Director
Plus imposes a similar surrender charge upon total or partial surrenders. Both
the Portfolio Director Plus and Independence Plus Contracts have other similar
provisions where surrender charges are not imposed. However, Portfolio Director
Plus provides at least one additional provision, not included in Independence
Plus Contracts, under which no surrender charge will be imposed. An additional
provision allows election of a systematic withdrawal method without surrender
charges. (See "Surrender Charge" in the prospectus.) For purposes of satisfying
the fifteen-year and five-year holding requirements described under "Surrender
Charge" in the prospectus, Portfolio Director Plus will be deemed to have been
issued on the same date as the Independence Plus Contract or certificate
thereunder, but no earlier than January 1, 1982. Purchase Payments exchanged
into Portfolio Director Plus and which were made within five years before the
date of exchange will be treated as Purchase Payments under Portfolio Director
Plus for purposes of calculating the surrender charge. Exchanged payments will
be deemed to have been made under Portfolio Director Plus on the date they were
made to Independence Plus Contracts for purposes of calculating the surrender
charge under Portfolio Director Plus.
 
     Other Charges. Under the Independence Plus Contracts, a maintenance charge
of $20 is assessed for the first year and an annual charge of $15 is assessed
for the second and later years during the accumulation period. The charge is due
in quarterly installments. A daily fee is charged at the annual rate of 1% of
the daily net asset value allocable to the Variable Subaccounts to cover
administrative expenses (other than those covered by the annual charge) and
mortality risks assumed by the Company. For Portfolio Director Plus, a quarterly
account maintenance fee of $3.75 is assessed for each calendar quarter during
the Purchase Period during which any Variable Account Option Account Value is
credited to a Participant's Account. The fee is to reimburse the Company for
some of the administrative expenses associated with the Variable Account
                                       17
<PAGE>   574
 
Options. No fee is assessed for any calendar quarter if the Account Value is
credited only to the Fixed Account Options throughout the quarter. Such fee
begins immediately if an exchange is made into any Variable Account Option
offered under Portfolio Director Plus. The fee may also be reduced or waived by
the Company for Portfolio Director Plus if the administrative expenses are
expected to be lower for that Contract. (See "Reduction or Waiver of Account
Maintenance Fee, Surrender, Mortality and Expense Risk Fee or Administration and
Distribution Fee Charges" in the prospectus). To cover expenses not covered by
the account maintenance fee and to compensate the Company for assuming mortality
risks and administration and distribution expenses under Portfolio Director
Plus, an additional daily charge with an annualized rate of 0.75% to 1.25% (or
lower amounts during the Purchase Period for different series of Portfolio
Director Plus), depending upon the Variable Account Options selected, if any, on
the daily net asset value of VALIC Separate Account A is attributable to
Portfolio Director Plus. (See "Separate Account Charges" and "Separate Account
Expense Reimbursement" in the prospectus.)
 
     Investment Options. Under Independence Plus Contracts ten divisions of
VALIC Separate Account A are available variable investment alternatives, each
investing in shares of a different underlying fund of AGSPC portfolio. The ten
mutual funds are managed by the Company for advisory fees at annual rates
ranging from .28% to .50% of each respective portfolio's average daily net
assets. In addition, two fixed investment options are available. Under Portfolio
Director Plus, fifty-three divisions of VALIC Separate Account A are available,
thirteen of which invest in different investment portfolios of AGSPC, eighteen
of which invest in different portfolios of AGSPC 3 and twenty-two of which
invest in other mutual fund portfolios. These mutual fund portfolios are managed
either by the Company, or other investment advisers for advisory fees at annual
rates ranging from 0.01% to 1.00% of each portfolio's or mutual fund's average
daily net assets. Two fixed investment options are also available.
 
     Annuity Options. Annuity options under Independence Plus Contracts provide
for payments on a fixed or variable basis, or a combination of both. The
Independence Plus Contract permits annuity payments for a designated period
between 3 and 30 years. Portfolio Director Plus permits annuity payments for a
designated period between of 5 and 30 years. Independence Plus Contracts and
Portfolio Director Plus both provide for "betterment of rates." Under this
provision, annuity payments for fixed annuities will be based on mortality
tables then being used by the Company, if more favorable to the Annuitant than
those included in the Contract.
 
EXCHANGES FROM V-PLAN CONTRACTS
 
     Sales/Surrender Charges. Under a V-Plan Contract, no sales charge is
deducted at the time a Purchase Payment is made, but a surrender charge may be
imposed on partial or total surrenders. The surrender charge is equal to 7% of
the Purchase Payments withdrawn within five years of the date such Purchase
Payments were made. The most recent Purchase Payments are deemed to be withdrawn
first. Up to 10% of the account value may be surrendered in a Participant Year
without any surrender charge being imposed. Portfolio Director Plus also imposes
a surrender charge upon total or partial surrenders. However, the surrender
charge under Portfolio Director Plus may not exceed 5% of any Purchase Payments
withdrawn within the most recent five years prior to the receipt of the
surrender request by the Company at its Home Office. V-Plan Contracts have other
provisions where surrender charges are not imposed. However, Portfolio Director
Plus provides at least two additional provisions, not included in V-Plan
Contracts, under which no surrender charge will be imposed. Those Portfolio
Director Plus provisions include no surrender charge on an election of the no
charge systematic withdrawal method, and where an employee-participant has
maintained the account for a period of five years and has attained the age
59 1/2. (See "Surrender Charge" in the prospectus.) For purposes of satisfying
the fifteen-year and five-year holding requirements, Portfolio Director Plus
will be deemed to have been issued on the same date as the V-Plan Contract or
certificate thereunder, but no earlier than January 1, 1982.
 
     If there is a total or partial surrender, Purchase Payments exchanged into
Portfolio Directors Plus and which were made within five years before the date
of exchange will be treated as Purchase Payments under Portfolio Director Plus
for purposes of calculating the surrender charge. Exchanged payments will be
deemed to have been made under Portfolio Director Plus on the date they were
made
                                       18
<PAGE>   575
 
to the V-Plan Contract for purposes of calculating the surrender charge under
Portfolio Director Plus.
 
     Other Charges. There are no administrative and risk charges under V-Plan
Contracts. For Portfolio Director Plus, a quarterly account maintenance fee of
$3.75 is assessed for each calendar quarter during the Purchase Period during
which any Variable Account Option Account Value is credited to a Participant's
Account. The fee is to reimburse the Company for some of the administrative
expenses associated with the Variable Account Options. No fee is assessed for
any calendar quarter if the Account Value is credited only to the Fixed Account
Options throughout the quarter. Such fees begin immediately if an exchange is
made into any Variable Account Option offered under Portfolio Director Plus. The
fee may also be reduced or waived by the Company on Portfolio Director Plus if
the administrative expenses are expected to be lower for that Contract. (See
"Reduction or Waiver of Account Maintenance Fee, Surrender, Mortality and
Expense Risk Fee or Administration and Distribution Fee Charges" in the
prospectus.) To cover expenses not covered by the account maintenance fee and to
compensate the Company for assuming mortality risks and administration and
distribution expenses under Portfolio Director Plus, an additional daily charge
with an annualized rate of 0.75% to 1.25% (or lower amounts during the Purchase
Period for different series of Portfolio Director Plus), depending upon the
Variable Account Options selected, if any, on the daily net asset value of the
VALIC Separate Account A is attributable to Portfolio Director Plus. (See
"Separate Account Charges" and "Separate Account Expense Reimbursement" in the
prospectus.)
 
     Investment Options. There are no variable investment alternatives provided
under V-Plan Contracts.
 
     Annuity Options. Annuity options under V-Plan Contracts provide for
payments on a fixed basis only. The V-Plan Contract permits annuity payments for
a designated period of 1 to 15 years. Under a V-Plan Contract, the designated
period option may, subject to adverse tax consequences, be commuted at any time
for its remaining value. Portfolio Director Plus permits Payout Payments for a
designated period of between 5 and 30 years on a fixed basis only. Under
Portfolio Director Plus, Payout Payments may be made on a fixed or variable
basis, or a combination of both. Portfolio Director Plus does not provide for
commutation. V-Plan Contracts and Portfolio Directors Plus both provide for
"betterment of rates." Under this provision, Payout Payments for fixed annuities
will be based on mortality tables then being used by the Company, if more
favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM SA-1 AND SA-2 CONTRACTS
(GUP-64, GUP-74, GTS VA CONTRACTS)
 
     Sales/Surrender Charges. Under the SA-1 and SA-2 Contracts a sales and
administrative charge is deducted from each Purchase Payment. This charge ranges
from 5% of the first $5,000 of Purchase Payments to 3% of Purchase Payments in
excess of $15,000. If a SA-1 or SA-2 Contract is exchanged for Portfolio
Director Plus the surrender charge under Portfolio Director Plus will not apply
to the amount of Account Value applied to Portfolio Director Plus ("Exchanged
Amount"). Purchase Payments made to Portfolio Director Plus, however, would be
subject to a surrender charge. In the case of a partial surrender, all Purchase
Payments to Portfolio Director Plus will be deemed to be withdrawn before any
Exchanged Amount is deemed to be withdrawn. No exchange pursuant to this offer
will be allowed within 120 days of a transfer of fixed accumulations under a
SA-1 or SA-2 Contract to the variable portion of such Contract. Under Portfolio
Director Plus, no sales charge is deducted at the time a Purchase Payment is
made, but a surrender charge may be imposed on partial or total surrenders. The
surrender charge may not exceed 5% of any Purchase Payments withdrawn within the
most recent five years prior to the receipt of the surrender request by the
Company at its Home Office. For purposes of this surrender charge, the most
recent Purchase Payments are deemed to be withdrawn first. (See "Surrender
Charge" in the prospectus.)
 
     Other Charges. A charge of a percentage of each Purchase Payment is made
for administrative expenses for SA-1 and SA-2 Contracts. The charge is generally
1.25% and is included in the above sales and administrative charge. An
additional daily charge (at an annual rate of 1% of total net assets
attributable to SA-1 Contracts and ranging from .21% to .85% of total net assets
attributable to SA-2 Contracts) is made for mortality and expense risks assumed
by the Company under the variable portion of the Contract. The total of these
expenses and other charges is limited to a maximum of the rate imposed on SA-1
and SA-2 Contracts on April 1,
 
                                       19
<PAGE>   576
 
1987. (See prospectus for SA-1 and SA-2 contracts dated April 20, 1987.) For
Portfolio Director Plus, a quarterly account maintenance fee of $3.75 is
assessed for each calendar quarter during the Purchase Period during which any
Variable Account Option Account Value is credited to a Participant's Account.
The fee is to reimburse the Company for some of the administrative expenses
associated with the Variable Account Options. No fee is assessed for any
calendar quarter if the Account Value is credited only to the Fixed Account
Options throughout the quarter. Such fee begins immediately if an exchange is
made into any Variable Account Option offered under Portfolio Director Plus. The
fee may also be reduced or waived by the Company on Portfolio Director Plus if
the administrative expenses are expected to be lower for that Contract. (See
"Reduction or Waiver of Account Maintenance Fee, Surrender, Mortality and
Expense Risk Fee or Administration and Distribution Fee Charges" in the
prospectus.) To cover expenses not covered by the account maintenance fee and to
compensate the Company for assuming mortality risks and administration and
distribution expenses under Portfolio Director Plus, an additional daily charge
with an annualized rate of 0.75% to 1.25% (or lower amounts during the Purchase
Period for different series of Portfolio Director Plus), depending upon the
Variable Account Options selected, if any, on the average daily net asset value
of the Separate Account is attributable to Portfolio Director Plus. (See
"Separate Account Charges" and "Separate Account Expense Reimbursement" in the
prospectus.)
 
     Investment Options. Under SA-1 and SA-2 Contracts only one division of
VALIC Separate Account A is available as a variable investment alternative. This
division invests in a portfolio of AGSPC. This portfolio is managed by the
Company for advisory fees at an annual rate of .28% of the portfolio's average
daily net assets. (Under a "grandfathering" arrangement, the total advisory fees
and certain other charges imposed against these Contracts are limited to a
maximum of the rate charged on April 1, 1987. See the prospectus for these
Contracts dated April 20, 1987.) Under Portfolio Director Plus, fifty-three
divisions of VALIC Separate Account A are available, thirteen of which invest in
different investment portfolios of AGSPC, eighteen of which invest in different
portfolios of AGSPC 3 and twenty-two of which invest in other mutual fund
portfolios. These mutual fund portfolios are managed by either the Company or
other investment managers, for advisory fees at annual rates ranging from 0.01%
to 1.00% of each portfolio's or mutual fund's average daily net assets. Two
fixed investment options are also available.
 
     Annuity Options. Annuity options under the SA-1 and SA-2 Contracts provide
for payments on a fixed or variable basis, or a combination of both. The SA-1
Contract annuity payments under a designated period option are limited to 15
years on a fixed basis only. Under this Contract, the designated period option
may, subject to adverse tax consequences, be commuted at any time for its
remaining value. SA-2 Contracts do not provide a designated period option nor do
they provide for commutation. Portfolio Director Plus permits Payout Payments
for a designated period of between 5 and 30 years. The SA-1 and SA-2 Contracts
make no provision for transfers from a separate account to a fixed annuity
during the annuity period. This option, subject to certain conditions, is
available under Portfolio Director Plus. The SA-1 Contracts provide an option
for monthly variable annuity payments to be made at a level payment basis during
each year of the annuity period. Portfolio Director Plus does not provide this
option. SA-1 and Portfolio Director Plus, but not SA-2 Contracts, both provide
for "betterment of rates." Under this provision, Payout Payments for fixed
annuities will be based on mortality tables then being used by the Company, if
more favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM IMPACT CONTRACTS
 
     Sales/Surrender Charges. Under an Impact Contract, no sales charge is
deducted at the time a Purchase Payment is made, but a surrender charge may be
imposed on partial or total surrenders. The surrender charge is equal to 5% of
the Purchase Payments withdrawn within three years of the date such Purchase
Payments were made. The most recent Purchase Payments are deemed to be withdrawn
first. Portfolio Director Plus also imposes a surrender charge upon total or
partial surrenders which may not exceed 5% of any Purchase Payments withdrawn
within the most recent five years prior to the receipt of the surrender request
by the Company at its Home Office. Portfolio Director Plus also has other
provisions where surrender charges are not imposed. (See "Exceptions to
Surrender Charge" in the prospectus.) For purposes of satisfying the
fifteen-year and five-year holding re-
 
                                       20
<PAGE>   577
 
quirements, Portfolio Director Plus will be deemed to have been issued on the
same date as the Impact Contract, or certificate thereunder, but no earlier than
January 1, 1982. Only Purchase Payments exchanged into a Portfolio Director Plus
which were made within three years before the date of exchange will be treated
as Purchase Payments under Portfolio Director Plus for purposes of calculating
the surrender charge. Exchanged payments will be deemed to have been made under
Portfolio Director Plus on the date they were made to Impact Contracts for
purposes of calculating the surrender charge under Portfolio Director Plus.
 
     Other Charges. Under Impact Contracts, a $30 annual charge is assessed once
a year to cover administrative expenses. The charge may, with prior regulatory
approval if required, be increased or decreased. In addition, a daily charge is
made at an annual rate of 1% of the net asset value allocable to the Impact
Contracts to cover administrative expenses (other than those covered by the
annual charge) and mortality risks assumed by the Company. For Portfolio
Director Plus, a quarterly account maintenance fee of $3.75 is assessed for each
calendar quarter during the Purchase Period during which any Variable Account
Option Account Value is credited to a Participant's Account. The fee is to
reimburse the Company for some of the administrative expenses associated with
the Variable Account Options. No fee is assessed for any calendar quarter if the
Account Value is credited only to the Fixed Account Options throughout the
quarter. Such fee begins immediately if an exchange is made into any Variable
Account Option offered under Portfolio Director Plus. The fee may also be
reduced or waived by the Company on Portfolio Director Plus if the
administrative expenses are expected to be lower for that Contract. (See
"Reduction or Waiver of Account Maintenance Fee, Surrender, Mortality and
Expense Risk Fee or Administration and Distribution Fee Charges" in the
prospectus.) To cover expenses not covered by the account maintenance fee and to
compensate the Company for assuming mortality risks and administration and
distribution expenses under Portfolio Director Plus, an additional daily charge
with an annualized rate of 0.75% to 1.25% (or lower amounts during the Purchase
Period for different series of Portfolio Director Plus), depending upon the
Variable Account Options selected, if any, on the daily net asset value of the
Separate Account is attributable to Portfolio Director Plus. (See "Separate
Account Charges" and "Separate Account Expense Reimbursement" in the
prospectus.)
 
     Investment Options. Under the Impact Contract five divisions of Separate
Account A are available as variable investment alternatives, each investing in
shares of a different underlying fund of AGSPC. The five mutual funds are
managed by the Company for advisory fees at annual rates ranging from .28% to
 .50% of each respective portfolio's average daily net assets. Under Portfolio
Director Plus, fifty-three divisions of VALIC Separate Account A are available,
thirteen of which invest in different investment portfolios of AGSPC, eighteen
of which invest in different portfolios of AGSPC 3 and twenty-two of which
invest in other mutual fund portfolios. These mutual fund portfolios are managed
by either the Company, or other investment managers, for advisory fees at annual
rates ranging from 0.01% to 1.00% of each portfolio's or mutual fund's average
daily net assets. Two fixed investment options are also available.
 
     Annuity Options. Annuity options under Impact Contracts provide for
payments on a fixed or variable basis, or a combination of both. The Impact
Contract permits annuity payments for a designated period of 1 to 15 years.
Under an Impact Contract, the designated period option may, subject to adverse
tax consequences, be commuted at any time for its remaining value. Portfolio
Director Plus permits Payout Payments for a designated period of between 5 and
30 years. Impact Contracts and the Portfolio Director Plus both provide for
"betterment of rates." Under this provision, Payout Payments for fixed annuities
will be based on mortality tables then being used by the Company, if more
favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM COMPOUNDER CONTRACTS
 
     Sales/Surrender Charges. Under a Compounder Contract a sales and
administrative charge is deducted from each Purchase Payment. This charge ranges
from 5% of the first $5,000 of Purchase Payments to 3% of Purchase Payments in
excess of $15,000. If a Compounder Contract is exchanged for Portfolio Director
Plus the surrender charge under Portfolio Director Plus will not apply to the
amount of Account Value applied to Portfolio Director Plus. Purchase Payments
made to Portfolio Director Plus, however, would be subject to the surrender
charge under Portfolio Director Plus. In
 
                                       21
<PAGE>   578
 
the case of a partial surrender, all Purchase Payments to Portfolio Director
Plus will be deemed to be withdrawn before any Exchanged Amount is deemed to be
withdrawn. Under Portfolio Director Plus, no sales charge is deducted at the
time a Purchase Payment is made, but a surrender charge may be imposed on
partial or total surrenders. The surrender charge may not exceed 5% of any
Purchase Payments withdrawn within the most recent five years prior to the
receipt of the surrender request by the Company at its Home Office. For purposes
of this surrender charge, the most recent Purchase Payments are deemed to be
withdrawn first. (See "Surrender Charge" in the prospectus.)
 
     Other Charges. A charge of a percentage of each Purchase Payment is made
for administrative expenses under a Compounder Contract. The charge is 1.25% and
is included in the above sales charge. For Portfolio Director Plus, a quarterly
account maintenance fee of $3.75 is assessed for each calendar quarter during
the Purchase Period during which any Variable Account Option Account Value is
credited to a Participant's Account. The fee is to reimburse the Company for
some of the administrative expenses associated with the Variable Account
Options. No fee is assessed for any calendar quarter if the Account Value is
credited only to the Fixed Account Options throughout the quarter. Such fee
begins immediately if an exchange is made into any Variable Account Option
offered under Portfolio Director Plus. The fee may also be reduced or waived by
the Company for Portfolio Director Plus if the administrative expenses are
expected to be lower for that Contract. (See "Reduction or Waiver of Account
Maintenance Fee, Surrender, Mortality and Expense Risk Fee or Administration and
Distribution Fee Charges" in this prospectus.) To cover expenses not covered by
the account maintenance fee and to compensate the Company for assuming mortality
risks and administration and distribution expenses under Portfolio Director
Plus, an additional daily charge with an annualized rate of 0.75% to 1.25% (or
lower amounts during the Purchase Period for different series of Portfolio
Director Plus), depending upon the Variable Account Options selected, if any, on
the daily net asset value of the Separate Account is attributable to Portfolio
Director Plus. (See "Separate Account Charges" and "Separate Account Expense
Reimbursement" in the prospectus.)
 
     Investment Options. There are no variable investment alternatives provided
under Compounder Contracts.
 
     Annuity Options. Payout Payments under a Compounder Contract are on a fixed
basis only and the designated period option is limited to a period of 15 years.
However, under a Compounder Contract, the designated period option may, subject
to adverse tax consequences, be commuted at any time for its remaining value.
Portfolio Director Plus allows Payout Payments be made on a fixed or variable
basis, or both. One option under the Portfolio Director 2 provides for a
designated period of 5 and 30 years. Unlike Portfolio Director 2, the Compounder
Contracts contain no "betterment of rates" provision.
 
INFORMATION WHICH MAY BE APPLICABLE TO
ANY EXCHANGE
 
     Guaranteed Annuity Rates. Mortality rates have improved since annuity rates
were developed for the other contracts. Therefore, the annuity rates guaranteed
in Portfolio Director Plus are less favorable to Contract Owners and Annuitants
than those guaranteed in the other contracts. However, the current annuity rates
being charged for fixed annuities under the "betterment of rates" provisions
discussed above are more favorable than those guaranteed under Portfolio
Director Plus or the other contracts. Of course, no assurance can be given that
this will continue to be true at the time of annuitization for a given contract.
Guaranteed annuity rate tables are set forth in your Contract or in current
endorsements thereto. Those guaranteed for Portfolio Director Plus are set forth
therein, and copies may be obtained from one of the Company's Regional Offices
listed on the inside back cover of this prospectus.
 
     To satisfy a federal tax law requirement, non-spouse beneficiaries under
Portfolio Director Plus generally must receive the entire benefit payable upon
the death of the Annuitant over their life expectancy or within five years of
the Annuitant's death. This requirement may be inapplicable to certain other
contracts or certificates issued before January 19, 1985 if not exchanged.

     a. Since this is the first partial surrender in this participant year,
        calculate the excess over 10% of the value of the Purchase Units
 
       10% of $39,000 = $3,900 [no charge on this 10% withdrawal]
 
     b. The Account Value upon which Surrender Charge on the Full Surrender may
        be calculated (levied) is $39,000 - $3,900 = $35,100
 
     c. The Surrender Charge calculated on the Account Value withdrawn $35,100 X
        .05 = $1,755
 
     d. Since only $29,000 has been paid in Purchase Payments in the 60 months
        prior to the Full Surrender, the charge can only be calculated on
        $29,000. The $3,900 partial withdrawal does not reduce this amount.
        Thus, the charge is $29,000 X (0.05) = $1,450.

31, 1998 ("base period"). It is computed by determining the net change,
exclusive of capital changes, in the value of a hypothetical pre-existing
account having a balance of one Purchase Unit at the beginning of the period,
subtracting a hypothetical charge reflecting deductions from Contract Owner
accounts, and dividing the difference by the value of the account at the

   ILLUSTRATION OF CALCULATION OF STANDARDIZED YIELD FOR BOND FUND DIVISIONS
    
 
     Example 7.
 
   
     The standardized yield quotation based on a 30-day period ended December
31, 1998 is computed by dividing the net investment income per Purchase Unit
earned during the period by the maximum offering price per Unit on the last day
of the period, according to the following formula:
    
 
                         YIELD = 2 [( a - b + 1)6 - 1]
                                      -----
                                       cd
 
     Where:
 
<TABLE>
                 <S>   <C>
                 a  =  net investment income earned during the period by the Fund
                       attributable to shares owned by the Division
 
                 b =   expenses accrued for the period (net of reimbursements)
 
                 c  =  the average daily number of Purchase Units outstanding
                       during the period
 
                 d =   the maximum offering price per Purchase Unit on the last day
                       of the period

     Yield on each Division is earned from dividends declared and paid by the
Fund, which are automatically reinvested in Fund shares.

                   CALCULATION OF AVERAGE ANNUAL TOTAL RETURN
 
   
     Average Annual Total Return quotations for the 1, 3, 5, and 10 year periods
ended December 31, 1998, the date of the most recent balance sheet included in
this registration statement, are computed by finding the average annual
compounded rates of over the 1, 3, 5, and 10 year periods that would equate the
initial amount invested to the ending redeemable value, according to the
following formula:
    
 
                                 P (1+T)n = ERV
 
     Where:
 
<TABLE>
                 <S>   <C>
                 P   = a hypothetical initial Purchase Payment of $1,000
                 T   = average annual total return
                 n   = number of years
                 ERV = redeemable value at the end of the 1, 3, 5 or 10 year
                       periods of a hypothetical $1,000 Purchase Payment made at
                       the beginning of the 1, 3, 5, or 10 year periods (or
                       fractional portion thereof)
</TABLE>
 
     The Company may advertise standardized average annual total return which,
includes the surrender charge of up to 5% of Gross Purchase Payments received
during the most recent 60 months as well as non-standardized average annual
total returns which does not include a surrender charge or maintenance fee.
 
   
     There is no sales charge for reinvested dividends. All recurring fees have
been deducted. For fees which vary with the account size, an account size equal
to that of the median account size has been assumed. Ending redeemable value has
been determined assuming a complete redemption at the end of the 1, 3, 5 or 10
year period and deduction of all nonrecurring charges at the end of each such
period.

PERFORMANCE INFORMATION
 
HYPOTHETICAL $10,000 ACCOUNT VALUE AND
CUMULATIVE RETURN AS COMPARED TO BENCHMARKS TABLES.
 
     The following tables show the Hypothetical $10,000 Account Value and
Cumulative Return for certain Divisions as compared to the benchmarks shown. For
different series of Portfolio Director Plus which may have lower charges during
the purchase period those amounts shown in the following tables will be higher.
 
     These performance calculations for the Divisions, and the methods used for
calculating them, are explained in the prospectus. (See "How To Review
Investment Performance of Separate Account Divisions" and "Variable Account
Options" in the prospectus.)
 
     These tables compare hypothetical investment performance and percentage
changes in Purchase Unit values with the results of several benchmarks,
representing unmanaged market indices. The performance information has been
adjusted to reflect mortality and expense risk fees and administration and
distribution fees, net of any expense reimbursements from the Underlying Fund.
Surrender charges, maintenance fees and premium taxes are not deducted. The
effect of these charges is to reduce total return to a Contract Owner. The
comparisons should be considered in light of the investment policies and
objectives of the Funds. Rates of return for the Divisions include reinvestment
of investment income, including capital gains, interest and dividends. The rates
of return on the market indices also have been adjusted to reflect reinvestment
of interest and dividends.
 
     Price returns for the market indices are calculated by subtracting the
price level at the beginning of the year from the price level at the end of the
year and dividing the difference by the price level at the beginning of the
year. To calculate dollar values for the indices' Hypothetical $10,000 Account
Value presentation, price index values were substituted for Unit values in the
calculation described in the prospectus, and where applicable, dividend yields
were then added to determine the total returns applied in the dollar value
calculations. Similarly, to calculate Cumulative Return for the indices, the
Cumulative Return calculation described in the prospectus for Unit values of the
Divisions is used, substituting the Hypothetical $10,000 Account Value at the
end of each year for the Purchase Unit Value. No sales load, administrative
charges, or any other expenses have been deducted from the index calculations.
 
     Additionally, the performance of a Division may from time to time be
compared with other Indexes which have been deemed by the Company relevant to
the Division.
 
     These benchmarks do not reflect any charges for investment advisory fees,
brokerage commissions or other fees and expenses of the type charged at either
the Separate Account or Fund level. Therefore, the comparisons with these
benchmarks are of limited use.
 
     THE PERFORMANCE RESULTS SHOWN IN THIS SECTION ARE NOT AN ESTIMATE OR
GUARANTEE OF FUTURE INVESTMENT PERFORMANCE, AND DO NOT REPRESENT THE ACTUAL
EXPERIENCE OF AMOUNTS INVESTED BY A PARTICULAR PARTICIPANT.
 
PERFORMANCE COMPARED TO MARKET INDICES
 
   
     The performance of AGSPC Asset Allocation Division Five may be compared to
a benchmark comprised of a weighted average of three market sectors in which the
Division, through the AGSPC Asset Allocation Fund, will invest. The base
allocation is: 55% in equity securities, 35% in intermediate or long-term debt
securities and 10% in money market or short-term debt securities. The Division's
actual asset allocation is determined daily by the Bankers Trust Asset
Allocation Model. The performance of the equity securities sector of the
Division may be compared to the S&P 500(R) Index. The performance of the
intermediate or long-term debt securities sector may be compared to the Merrill
Lynch Corporate and Government Master Index. The Merrill Lynch Corporate and
Government Master Index consists of an index of approximately 5,000 corporate
and government bond holdings. The average maturity of these corporate bond
holdings is approximately 10 years. The performance of the money market or
short-term debt securities sector may be compared to the Certificate of Deposit
Primary Offering by New York City Banks, 30 Day Index.

                                PAYOUT PAYMENTS
 
ASSUMED INVESTMENT RATE
 
     The discussion concerning the amount of payout payments which follows this
section is based on an Assumed Investment Rate of 3 1/2% per annum. However, the
Company will permit each Annuitant choosing a variable payout option to select
an Assumed Investment Rate permitted by state law or regulations other than the
3 1/2% rate described in this prospectus as follows: 3%, 4 1/2%, 5% or 6% per
annum. (Note: an Assumed Investment Rate higher than 5% may not be selected
under individual Contracts.) The foregoing Assumed Investment Rates are used
merely in order to determine the first monthly payment per thousand dollars of
value. It should not be inferred that such rates will bear any relationship to
the actual net investment experience of VALIC Separate Account A.
 
AMOUNT OF PAYOUT PAYMENTS
 
     The amount of the first variable annuity payment to the Annuitant will
depend on the amount of the Account Value applied to effect the variable annuity
as of the tenth day immediately preceding the date payout payments commence, the
amount of any premium tax owed, the annuity option selected, and the age of the
Annuitant.
 
     The Contracts contain tables indicating the dollar amount of the first
payout payment under each payout option for each $1,000 of Account Value (after
the deduction for any premium tax) at various ages. These tables are based upon
the Annuity 2000 Table (promulgated by the Society of Actuaries) and an Assumed
Investment Rate of 3%, 3 1/2%, 4% and 5% per annum (3 1/2% in the group
Contract).
 
     The portion of the first monthly variable payout payment derived from a
Division of VALIC Separate Account A is divided by the Payout Unit value for
that Division (calculated ten days prior to the date of the first monthly
payment) to determine the number of Payout Units in each Division represented by
the payment. The number of such units will remain fixed during the Payout
Period, assuming the Annuitant makes no transfers of Payout Units to provide
Payout Units under another Division or to provide a fixed annuity.
 
     In any subsequent month, the dollar amount of the variable payout payment
derived from each Division is determined by multiplying the number of Payout
Units in that Division by the value of such Payout Unit on the tenth day
preceding the due date of such payment. The Payout Unit value will increase or
decrease in proportion to the net investment return of the Division or Divisions
underlying the variable payout since the date of the previous payout payment,
less an adjustment to neutralize the 3 1/2% or other Assumed Investment Rate
referred to above.
 
     Therefore, the dollar amount of variable payout payments after the first
will vary with the amount by which the net investment return is greater or less
than 3 1/2% per annum. For example, if a Division has a cumulative net
investment return of 5% over a one year period, the first payout payment in the
next year will be approximately 1 1/2 percentage points greater than the payment
on the same date in the preceding year, and subsequent payments will continue to
vary with the investment experience of the Division. If such net investment
return is 1% over a one year period, the first payout payment in the next year
will be approximately 2 1/2 percentage points less than the payment on the same
date in the preceding year, and subsequent payments will continue to vary with
the investment experience of the applicable Division.
 
     Each deferred Contract provides that, when fixed payout payments are to be
made under one of the first four payout options, the monthly payment to the
Annuitant will not be less than the monthly payment produced by the then current
settlement option rates, which will not be less than the rates used for a
currently issued single payment immediate annuity contract. The purpose of this
provision is to assure the Annuitant that, at retirement, if the fixed payout
purchase rates then required by the Company for new single payment immediate
annuity contracts are significantly more favorable than the annuity rates
guaranteed by a Contract, the Annuitant will be given the benefit of the new
annuity rates.
 
PAYOUT UNIT VALUE
 
     The value of a Payout Unit is calculated at the same time that the value of
an Purchase Unit is calculated and is based on the same values for Fund
 
                                       58
<PAGE>   615
shares and other assets and liabilities. (See "Purchase Period" in the
prospectus.) The calculation of Payout Unit value is discussed in the prospectus
under "Payout Period."
 
     The following illustrations show, by use of hypothetical examples, the
method of determining the Payout Unit value and the amount of variable annuity
payments.

                   DISTRIBUTION OF VARIABLE ANNUITY CONTRACTS
 
     The Company has qualified or intends to qualify the Contracts for sale in
all fifty states and the District of Columbia and will commence offering the
Contracts promptly upon qualification in each such jurisdiction.
 
   
     The Contracts are sold in a continuous offering by licensed insurance
agents who are registered representatives of broker-dealers which are members of
the National Association of Securities Dealers, Inc. (the "NASD"). The principal
underwriter for VALIC Separate Account A is A.G. Distributors, an affiliate of
VALIC. A.G. Distributors' address is 2929 Allen Parkway, Houston, Texas 77019.
A.G. Distributors is a Delaware corporation organized in 1994 and is a member of
the NASD.
    
 
   
     The licensed agents who sell the Contracts will be compensated for such
sales by commissions ranging up to 6.0% of each Purchase Payment. Managers who
supervise the agents will receive overriding commissions ranging up to 1% of
Purchase Payments. These various commissions are paid by the Company and do not
result in any charge to Contract Owners or to VALIC Separate Account A in
addition to the charges described under "Fees and Charges" in the prospectus.
    
 
   
     Pursuant to its underwriting agreement with A.G. Distributors and VALIC
Separate Account A, the Company reimburses A.G. Distributors for reasonable
sales expenses, including overhead expenses. Prior to May 1, 1999, The Variable
Annuity Marketing Company (VAMCO) was the principal underwriter for VALIC
Separate Account A. The sales commission paid for the year 1998 was $5,403.
VAMCO retained $0 commission for the year 1998.

Report of Independent Auditors



To the Board of Directors
The Variable Annuity Life Insurance Company





         We have audited the accompanying consolidated balance sheets of The
Variable Annuity Life Insurance Company and Subsidiaries as of December 31, 1998
and 1997, and the related consolidated statements of income, changes in
stockholder's equity, comprehensive income, and cash flows for each of the three
years in the period ended December 31, 1998. These financial statements are the
responsibility of the company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

         We conducted our audits 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 statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. 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 audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of The
Variable Annuity Life Insurance Company and Subsidiaries at December 31, 1998
and 1997, and the consolidated results of their operations and their cash flows
for each of the three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles.

                   THE VARIABLE ANNUITY LIFE INSURANCE COMPANY
- --------------------------------------------------------------------------------
Notes to Consolidated Financial Statements

December 31, 1998
All dollar amounts in thousands, except per share data
- --------------------------------------------------------------------------------

                                        1
                        SIGNIFICANT ACCOUNTING POLICIES

1.1  INTRODUCTION


     The Variable Annuity Life Insurance Company (VALIC), an indirect, wholly
owned subsidiary of American General Corporation (AGC), provides tax-deferred
retirement annuities and employer-sponsored retirement plans to employees of
educational, health care, public sector and not-for-profit organizations. VALIC
markets products nationwide through exclusive sales representatives.

     VALIC is 100% owned by American General Life Insurance Company (AGL), a
wholly owned subsidiary of AGC Life Insurance Company (AGC Life). AGC Life is a
wholly owned subsidiary of AGC. A summary of the accounting policies followed in
the preparation of the consolidated financial statements is set forth below.

1.2  PREPARATION OF FINANCIAL STATEMENTS

     The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles (GAAP) and include the accounts of
VALIC and its wholly owned subsidiaries. All material intercompany transactions
have been eliminated in consolidation.

     The preparation of financial statements requires management to make
estimates and assumptions that affect amounts reported in the financial
statements and disclosures of contingent assets and liabilities. Ultimate
results could differ from these estimates.

1.3  ACCOUNTING CHANGES

     COMPREHENSIVE INCOME. During 1998, VALIC adopted Statement of Financial
Accounting Standards (SFAS) 130, "Reporting Comprehensive Income," which
establishes standards for reporting and displaying comprehensive income and its
components in the financial statements. VALIC elected to report comprehensive
income and its components in a separate statement of comprehensive income.
Adoption of this statement did not change recognition or measurement of net
income and, therefore, did not impact VALIC's consolidated results of operations
or financial position.

     DERIVATIVES. In June 1998, the Financial Accounting Standards Board issued
SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," which
requires all derivative instruments to be recognized at fair value as either
assets or liabilities in the balance sheet. Changes in the fair value of a
derivative instrument are to be reported as earnings or other comprehensive
income, depending upon the intended use of the derivative instrument. This
statement is effective for years beginning after June 15, 1999. Adoption of SFAS
133 is not expected to have a material impact on VALIC's consolidated results of
operations or financial position.

1.4  INVESTMENTS

     FIXED MATURITY AND EQUITY SECURITIES. At year end, all fixed maturity and
equity securities are classified as available-for-sale and recorded at fair
value. After adjusting related balance sheet accounts as if the unrealized gains
(losses) had been realized, the net adjustment is recorded in accumulated other
comprehensive income within stockholder's equity. If the fair value of a
security classified as available-for-sale declines below its cost and this
decline is considered to be other than temporary, the security is reduced to its
fair value, and the reduction is recorded as a realized loss.

     During 1998, VALIC maintained a trading portfolio of certain fixed maturity
securities. Trading securities are recorded at fair value. Unrealized gains
(losses), as well as realized gains (losses), are included in net investment
income. VALIC held no trading securities at December 31, 1998, and trading
securities did not have a material effect on net investment income.

     MORTGAGE LOANS. Mortgage loans are reported at amortized cost, net of an
allowance for losses. The allowance for losses covers all non-performing loans
and loans for which management has a concern based on its assessment of risk
factors, such as potential non-payment or non-monetary default. The allowance is
based on a loan-specific review and a formula that reflects past results and
current trends.

     Loans for which VALIC determines that collection of all amounts due under
the contractual terms is not probable are considered to be impaired. VALIC
generally looks to the underlying collateral for repayment of impaired loans.
Therefore, impaired loans are considered to be collateral dependent and are
reported at the lower of amortized cost or fair value of the underlying
collateral, less estimated costs to sell.

     POLICY LOANS. Policy loans are reported at unpaid principal balance.

     INVESTMENT INCOME. Interest on fixed maturity securities and performing
mortgage loans is recorded as income when earned and is adjusted for any
amortization of premium or discount. Interest on delinquent mortgage loans is
recorded as income when received. Dividends are recorded as income on
ex-dividend dates.

     REALIZED INVESTMENT GAINS (LOSSES). Realized investment gains (losses) are
recognized using the specific identification method.

1.5  DERIVATIVES RELATED TO INVESTMENTS

     VALIC's use of derivative financial instruments is generally limited to
interest rate and currency swap agreements, and options to enter into interest
rate swap agreements (call swaptions). VALIC accounts for its derivative
financial instruments as hedges.

     INTEREST RATE AND CURRENCY SWAP AGREEMENTS. Interest rate swap agreements
are used to convert specific investment securities from a floating-rate to a
fixed-rate basis, or vice versa. Currency swap agreements are used to convert
cash flows from specific investment securities denominated in foreign currencies
into U.S. dollars at specified exchange rates, and to hedge against currency
rate fluctuations on anticipated security purchases.

1.5  DERIVATIVES RELATED TO INVESTMENTS-(CONTINUED)

     The difference between amounts paid and received on swap agreements is
recorded on an accrual basis as an adjustment to investment income over the
periods covered by the agreements. The related amount payable to or receivable
from counterparties is included in other liabilities or assets.

     The fair values of swap agreements are recognized in the consolidated
balance sheet if they hedge investments carried at fair value or if they hedge
anticipated purchases of such investments. In this event, changes in the fair
value of a swap agreement are reported in accumulated other comprehensive income
included in stockholder's equity, consistent with the treatment of the related
investment security.

     For swap agreements hedging anticipated investment purchases, the net swap
settlement amount or unrealized gain or loss is deferred and included in the
measurement of the anticipated transaction when it occurs.

     Swap agreements generally have terms of two to ten years. Any gain or loss
from early termination of a swap agreement is deferred and amortized into income
over the remaining term of the related investment. If the underlying investment
is extinguished or sold, any related gain or loss on swap agreements is
recognized in income.

     Swaptions. Options to enter into interest rate swap agreements are used to
limit VALIC's exposure to reduced spreads between investment yields and interest
crediting rates should interest rates decline significantly over prolonged
periods.

     During prolonged periods of decreasing interest rates, the spread between
investment yields and interest crediting rates may be reduced as a result of
minimum rate guarantees on certain insurance and annuity contracts, which limit
VALIC's ability to reduce interest crediting rates. Call swaptions, which allow
VALIC to enter into interest rate swap agreements to receive fixed rates and pay
lower floating rates, effectively maintain the spread between investment yields
and interest crediting rates during such periods.

     During prolonged periods of increasing interest rates, the spread between
investment yields and interest crediting rates may be reduced as a result of
VALIC's decision to increase interest crediting rates to limit surrenders. Put
swaptions, which allow VALIC to enter into interest rate swap agreements to pay
fixed rates and receive higher floating rates, effectively maintain the spread
between investment yields and interest crediting rates during such periods.

     Premiums paid to purchase swaptions are included in investments and are
amortized to net investment income over the exercise period of the swaptions. If
a swaption is terminated, any gain is deferred and amortized to insurance and
annuity benefits over the expected life of the insurance and annuity contracts
and any unamortized premium is charged to income. If a swaption ceases to be an
effective hedge, any gain or loss is recognized in income.

1.6  DEFERRED POLICY ACQUISITION COSTS (DPAC)

     Certain costs of writing an insurance policy, including commissions,
underwriting and marketing expenses, are deferred and reported as DPAC. DPAC is
charged to expense in relation to the estimated gross profits of the insurance
contracts, including realized gains (losses).

     DPAC is adjusted for the impact on estimated future gross profits as if net
unrealized gains (losses) on securities had been realized at the balance sheet
date. The impact of this adjustment is included in accumulated other
comprehensive income within stockholder's equity.

     VALIC reviews the carrying value of DPAC on at least an annual basis.
Management considers estimated future gross profit margins as well as expected
mortality, interest earned and credited rates, persistency, and expenses in
determining whether the carrying amount is recoverable.

1.7  SEPARATE ACCOUNTS

     Separate Accounts are assets and liabilities associated with certain
contracts, principally annuities for which the investment risk lies solely with
the holder of the contract rather than VALIC. Consequently, VALIC's liability
for these accounts equals the value of the account assets. Investment income,
realized investment gains (losses) and policyholder account deposits and
withdrawals related to Separate Accounts are excluded from the consolidated
statements of income and cash flows. Assets held in the Separate Accounts are
primarily shares in mutual funds, which are carried at fair value, based on the
quoted net asset value per share.

1.8  POLICY RESERVES

     Net deposits made by fixed annuity policyholders are accumulated at
interest rates guaranteed by VALIC plus excess interest credited at the sole
discretion of the Board of Directors until benefits are payable. Reserves for
deferred annuities (accumulation phase) are equivalent to the policyholders'
account values. Reserves for annuities on which benefits are currently payable
(annuity payout phase) are provided based upon estimated mortality and other
assumptions, including provisions for the risk of adverse deviation from
assumptions, which were appropriate at the time the contracts were issued. The
1971 Individual or Group Annuity Mortality Tables, and the 1983a Table have been
used to provide for future annuity benefits in the annuity payout phase.
Interest rates used in determining reserves for policy benefits during both the
accumulation and annuity payout phases range from 3.5% to 13.5%.

1.9  RECOGNITION OF REVENUES AND COSTS

     Premium receipts for annuity contracts are classified as deposits instead
of revenues. Revenues for these contracts consist of the mortality, expense and
surrender charges. Gains (losses) from mortality guarantees under variable
annuity contracts are recognized as they occur.

1.10 INCOME TAXES

     Deferred tax assets and liabilities are established for temporary
differences between the financial reporting basis and the tax basis of assets
and liabilities, at the enacted tax rates expected to be in effect when the
temporary differences reverse. The effect of a tax rate change is recognized in
income in the period of enactment. State income taxes are included in income tax
expense.

     A valuation allowance for deferred tax assets is provided if all or some
portion of the deferred tax asset may not be realized. An increase or decrease
in a valuation allowance that results from a change in circumstances that causes
a change in judgment about the realizability of the related deferred tax asset
is included in income. A change related to fluctuations in fair value of
available-for-sale fixed maturity securities is included in accumulated other
comprehensive income in stockholder's equity.

1.11 STATUTORY ACCOUNTING

     State insurance laws and regulations prescribe accounting practices for
calculating statutory net income and equity (capital and surplus) that differ
from GAAP. Net income and stockholder's equity as determined by statutory
accounting practices at December 31 were as follows:

1.12 COINSURANCE TRANSACTION

     On May 21, 1998, VALIC completed the acquisition of a block of individual
annuity business in a coinsurance transaction. This transaction increased assets
and insurance and annuity liabilities by $688,221.

     The carrying value of investments that produced no investment income during
1998 totaled $313 or 0.001% of total invested assets. The ultimate disposition
of these assets is not expected to have a material effect on VALIC's
consolidated results of operations or financial position.

     Derivative financial instruments related to investment securities did not
have a material effect on net investment income in any of the three years ended
December 31, 1998.

company. VALIC and the Separate Accounts are included in the consolidated life
insurance company tax return of AGC. VALIC participates in a tax-sharing
agreement with the other companies included in the consolidated return. Under
this agreement, tax payments are made to AGC as if the companies filed separate
tax returns and companies incurring operating losses and/or capital losses are
reimbursed for the use of these losses by the consolidated return group.

                                 CAPITAL STOCK

     VALIC has two classes of capital stock: preferred stock ($1.00 par value
with 2 million shares authorized) that may be issued with such dividend,
liquidation, redemption, conversion, voting and other rights as the Board of
Directors may determine, and common stock ($1.00 par value, 5 million shares
authorized).

     VALIC is restricted by state insurance laws as to the amount it may pay as
dividends without prior approval from the Texas Department of Insurance. The
maximum dividend payout which may be made without prior approval in 1999 is
$176,753.

</TABLE>


     During 1998, VALIC purchased call swaptions and put swaptions that expire
by 2000. The call swaptions had a notional amount of $950,000 and strike rates
ranging from 3.5% to 4.5% at December 31, 1998. The put swaptions had a notional
amount of $690,000 strike rates ranging from 8.0% to 8.5% at December 31, 1998.
Should the strike rates remain below market rates for call swaptions and above
market rates for put swaptions, the swaptions will expire, and VALIC's exposure
would be limited to the premiums paid. These premiums were immaterial.

     CREDIT AND MARKET RISK. Derivative financial instruments expose VALIC to
credit risk in the event of nonperformance by counterparties. VALIC limits this
exposure by entering into agreements with counterparties having high credit
ratings and by regularly monitoring the ratings. VALIC does not expect any
counterparty to fail to meet its obligation; however, nonperformance would not
have a material impact on VALIC's consolidated results of operations and
financial position.

     VALIC's exposure to market risk is mitigated by the offsetting effects of
changes in the value of the agreements and the related items being hedged.

drawing conclusions based on fair value, since (1) the fair values presented do
not include the value associated with all VALIC's assets and liabilities, and
(2) the reporting of investments at fair value without a corresponding

*    Includes derivative financial instruments with a fair value of $19,342 in

     The following methods and assumptions were used to estimate the fair values
of financial instruments.

     FIXED MATURITY AND EQUITY SECURITIES. Fair values of fixed maturity and
equity securities were based on quoted market prices, where available. For
investments not actively traded, fair values were estimated using values
obtained from independent pricing services or, in the case of some private
placements, by discounting expected future cash flows using a current market
rate applicable to yield, credit quality and average life of the investments.

     MORTGAGE LOANS ON REAL ESTATE. Fair value of mortgage loans was estimated
primarily using discounted cash flows, based on contractual maturities and
risk-adjusted discount rates.

     POLICY LOANS. Fair value of policy loans was estimated using discounted
cash flows and actuarially-determined assumptions, incorporating market rates.

     INSURANCE INVESTMENT CONTRACTS. Fair value of insurance investment
contracts was estimated using cash flows discounted at market interest rates.

                     TRANSACTIONS WITH AFFILIATED COMPANIES

     In the ordinary course of business, VALIC is occasionally involved in
transactions with affiliated companies. Transactions involving the purchase or
disposal of securities are consummated at the market value of the security on
the date of the transaction. Transactions with affiliated companies during each
of the three years in the period ended December 31, 1998 were as follows:

     Operating expenses include $46,556 in 1998, $22,061 in 1997, and $17,533 in
1996, for amounts paid to AGC or its subsidiaries primarily for rent, data
processing services, use of facilities and investment expenses. Interest paid on
borrowings from AGC totaled $152 in 1998, $501 in 1997, and $455 in 1996.

     On November 4, 1982, VALIC invested $11,853 in 13 1U2% Restricted
Subordinated Note due November 4, 2002 issued by AGC. The principal amount of
the note is due November 4, 2002. Principal payments of $592 were received on
November 4, 1998, 1997, and 1996. VALIC recognized $1,212 in interest income
during 1998, $1,292 for 1997, and $1,372 for 1996.

     On December 31, 1984, VALIC entered into a $48,929 note purchase agreement
with AGC. Under the agreement AGC issued an adjustable rate promissory note in
exchange for VALIC's holdings of AGC preferred stock, common stock and warrants.
The principal amount of the note is due in 20 equal installment payments
commencing December 29, 1985 and concluding December 29, 2004. Principal
payments of $2,446 were received on December 29, 1998, 1997, and 1996. VALIC
recognized $1,048, $1,296, and $1,479 of interest income on the note during
1998, 1997, and 1996, respectively.

     On May 15, 1996, VALIC sold SC Financial Corp Mortgage Notes with a book
value of $13,000 to American General Life Insurance Company of NY. Proceeds from
the sale totaled $13,033 with a profit of $33 recognized on the transaction.

     VALIC paid common stock dividends of $181,000, $50.63 per share; $379,000,
$106.01 per share; and $111,000, $31.05 per share, in 1998, 1997, and 1996,
respectively.

     VALIC received capital contributions of $55,200, $67,000, $250,000, and
$75,000 from AGL on June 30, 1998, December 31, 1998, March 31, 1997, and
December 30, 1996, respectively.

9.   TRANSACTIONS WITH AFFILIATED COMPANIES - (CONTINUED)

     VALIC acquired bonds of various issuers from American General Life and
Accident Insurance Company at a cost of $22,154 and $25,892 on January 30, 1997,
and April 8, 1997, respectively.

     On December 5, 1997, VALIC acquired bonds of various issuers from Western
National Life Insurance Company at a cost of $129,715.

                         COMMITMENTS AND CONTINGENCIES

     VALIC is a defendant in various lawsuits arising in the normal course of
business. VALIC believes it has valid defenses in these lawsuits and is
defending the cases vigorously. VALIC also believes that the total amounts that
would ultimately have to be paid arising from these lawsuits would have no
material effect on its consolidated financial position.

     All 50 states have laws requiring solvent life insurance companies to pay
assessments to state guaranty associations to protect the interests of
policyholders of insolvent life insurance companies. State guaranty fund expense
included in operating costs and expenses was $37, $30, and $2,678, for the years
ended December 31, 1998, 1997, and 1996, respectively. The accrued liability for
anticipated assessments was $4,782, $7,402, and $13,661, at December 31, 1998,
1997, and 1996, respectively. The 1998 liability was estimated by VALIC using
the latest information available from the National Organization of Life and
Health Insurance Guaranty Associations. Although the amount accrued represents
VALIC's best estimate of its liability, this estimate may change in the future.
Additionally, changes in state laws could decrease the amount recoverable
against future premium taxes.

                             EMPLOYEE BENEFIT PLANS

11.1 PENSION PLANS

     VALIC participates in several employee benefit plans which together cover
substantially all of its employees. One of these plans is a defined benefit
plan. Pension benefits under this plan are based on the participant's average
monthly compensation and length of credited service. VALIC's funding policy for
this plan is to contribute annually no more than the maximum amount that can be
deducted for federal income tax purposes.

11.1 PENSION PLANS - (CONTINUED)

     The components of pension expense and underlying assumptions for the
defined benefit plan were as follows:

     Equity and fixed maturity securities were 66% and 32%, respectively, of the
plan's assets at the plan's most recent balance sheet dates. The remaining plan
assets consisted primarily of cash equivalents and investment-related
receivables.

11.2 POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

     VALIC, through AGC, has life, medical, supplemental major medical, and
dental plans for certain retired employees and agents. Most plans are
contributory, with retiree contributions adjusted annually to limit employer
contributions to predetermined amounts. VALIC has reserved the right to change
or eliminate these benefits at any time.

11.2 POSTRETIREMENT BENEFITS OTHER THAN PENSIONS - (CONTINUED)

     The life plans are fully insured; the retiree medical and dental plans are
unfunded and self-insured. The accrued liability for postretirement benefits was
$2,388 and $1,784 at year-end 1998 and 1997, respectively. These liabilities
were discounted at the same rates used for the pension plans. Postretirement
benefit expense in 1998, 1997, and 1996 was $275, $295, and $282, respectively.

                        IMPACT OF YEAR 2000 (UNAUDITED)

     INTERNAL SYSTEMS. VALIC has numerous technology systems that are managed on
a decentralized basis. Year 2000 readiness efforts are therefore being
undertaken by its key business units with centralized oversight. Each business
unit has developed and is implementing a plan to minimize the risk of a
significant negative impact on its operations.

     While the specifics of the plans vary, the 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) reprogram or
replace systems that are not Year 2000 ready, (4) test systems to prove that
they will function into the next century as they do currently, and (5) return
the system to operations. As of December 31, 1998, these activities have been
completed for substantially all of VALIC's critical systems, making them Year
2000 ready. Vendor upgrades for a small number of systems are expected in the
first half of 1999; therefore, activities (3) through (5) are ongoing for these
systems. VALIC will continue to test its systems throughout 1999 to maintain
Year 2000 readiness.

     THIRD PARTY RELATIONSHIPS. VALIC has relationships with various third
parties who also must be Year 2000 ready. These third parties provide (or
receive) resources and services to (or from) VALIC and include organizations
with which VALIC exchanges information. Third parties include vendors of
hardware, software, and information services; providers of infrastructure
services such as voice and data communications and utilities for office
facilities; investors; customers; distribution channels; and joint venture
partners. Third parties differ from internal systems in that VALIC exercises
less, or no, control over their Year 2000 readiness. VALIC has developed a plan
to assess and attempt to mitigate the risks associated with the potential
failure of third parties to achieve Year 2000 readiness. The plan includes the
following activities: (1) identify and classify third party dependencies; (2)
research, analyze, and document Year 2000 readiness for critical third parties;
and (3) test critical hardware and software products and electronic interfaces.
A more detailed evaluation will be completed during first quarter 1999 as part
of VALIC's contingency planning efforts. Due to the various stages of third
parties' Year 2000 readiness, VALIC's testing activities will extend throughout
1999.

     CONTINGENCY PLANS. VALIC has commenced contingency planning to reduce the
risk of Year 2000 related business failures. The contingency plans, which
address both internal systems and third party relationships, include the
following activities: (1) evaluate the consequences of failure of business
processes with significant exposure to Year 2000 risk, (2) determine the
probability of a Year 2000-related failure for those processes that have a high
consequence of failure; (3) develop an action plan to complete contingency plans
for those processes that rank high in consequence and probability of failure;
and (4) complete the applicable action plans. VALIC is currently developing
contingency plans and expects to substantially complete all contingency-planning
activities by April 30, 1999.

     RISKS AND UNCERTAINTIES. Based on its plans to make internal systems ready
for Year 2000, to deal with third party relationships, and to develop
contingency actions, VALIC believes that it will experience, at most, isolated
and minor disruptions of business processes following the turn of the century.
Such disruptions are not expected to have a material effect on VALIC's future
results of operations, liquidity, or financial condition. However, due to the
magnitude and complexity of this project, risks and uncertainties exist and
VALIC is not able to predict a most reasonably likely worst case scenario. If
Year 2000 readiness is not achieved due to nonperformance by significant third
party vendors, VALIC's failure to maintain critical systems as Year 2000 ready,
failure of critical third parties to achieve Year 2000 readiness on a timely
basis, or other unforeseen circumstances in completing VALIC's plans, the Year
2000 issues could have a material adverse impact on VALIC's operations following
the turn of the century.

     COSTS. Through December 31, 1998, VALIC has incurred and expensed $27
million (pretax) related to Year 2000 readiness, including $20 million incurred
during 1998. VALIC currently anticipates that it will incur future costs of
approximately $2 million (pretax) to maintain Year 2000 readiness, complete Year
2000 work on noncritical systems and third party relationships, and complete
contingency planning activities. In addition, VALIC accelerated the planned
replacement of certain systems as part of the Year 2000 plans.

                                CHAIRMAN'S LETTER                              1
================================================================================



TO OUR PARTICIPANTS:

We are pleased to present the December 31, 1998, Annual Report to Contract
Owners for Separate Account A of The Variable Annuity Life Insurance Company. A
summary of the change in unit value for each fund and each product series
(Portfolio Director 1, Portfolio Director 2, Portfolio Director Plus,
Independence Plus, Group Unit Purchase and Impact) appears on pages two and
three.

1998 was a volatile year for investors around the world. Problems that began in
Asia in late 1997 circled the globe throughout 1998. Central banks, fearing the
worst lowered interest rates in the fourth quarter of 1998. The result was an
unexpected and dramatic rise in stock and bond prices worldwide.

The year was marked by extreme flight to quality. Investors general preference
was for larger cap growth in stocks over small cap value stocks, and U.S.
Treasury Securities.

The Standard & Poor's 500 Index, dominated by large cap, high-growth technology
and global consumer product companies, had a total return of 28.58%. The top 15
stocks alone accounted for half of the performance. It was a difficult year for
active equity fund managers, as almost 90% of the active managers lagged the S&P
500 Index returns. Also, the S&P 500 Index returns for the year outperformed
over 71% of all U.S.-traded common stocks. The medium to small-cap companies
lagged, with the large companies S&P MidCap 400 Index returning 6.27% and the
S&P SmallCap 600 Index, producing a negative 1.31%.

There was a greater variability in returns between growth and value components
of the equity indices. In the large capitalization arena, S&P 500/BARRA Growth
Index returned an outstanding 42.16%, while the S&P 500/BARRA Value Index
returned 14.67%. In the mid-cap sector, the S&P 400/BARRA Growth Index returned
34.86% compared to the S&P 400/BARRA Value Index return of 4.67%. However, the
small cap equity returns experienced wide variability, with the S&P SmallCap
600/BARRA Growth Index returning 2.29%, and the S&P SmallCap 600/BARRA Value
returning a negative 5.06%.

Globally, the pattern of investment results was very similar to the U.S. equity
returns. The MSCI world Index returned 22%. The top quintile of growth stocks
outperformed the bottom quintile of value stocks by over two times with returns
of 48% and 17%, respectively.

The yield on the 30 year Treasury bond opened the year at 5.92% and declined to
5.10% by the end of 1998, as the Federal Reserve lowered the federal fund rate
three times between September 29 and November 17, leaving the target rate at
4.75%.

For the year, the bond market return, reflected in the Lehman Aggregate Bond
Index, was 8.69% with the long U.S. Treasury Index showing the highest return of
13.52%, followed by the Long Corporate AA/Better Index 10.52%, and the High
Yield Index with 1.60%. Throughout the developed world international bond prices
appreciated as yields declined.

While international markets outside of North America and Europe remain
unsettled, the U.S. economy is experiencing unprecedented prosperity and growth.
Furthermore, with worldwide inflation rates low, and the Federal Reserve weary
of weakness in Asia and emerging markets, it appears that we can expect a
continuation of the current stable rate environment.

If you have any questions about your contract or this report, we would be happy
to hear from you.

                                  Respectfully,


                                  /s/ THOMAS L. WEST, JR.


                                  Thomas L. West, Jr., Chairman 
                                  The Variable Annuity Life Insurance Company



February 18, 1999

NOTE B -- SUMMARY OF SIGNIFICANT 
          ACCOUNTING POLICIES

         The assets of the Separate Account are part of VALIC. The following is
a summary of significant accounting policies consistently followed by the
Separate Account in the preparation of its financial statements.

         USE OF ESTIMATES. The financial statements have been prepared in
conformity with generally accepted accounting principles. The preparation of
financial statements requires management to make estimates and assumptions that
affect amounts reported in the financial statements and disclosure of contingent
assets and liabilities. Ultimate results could differ from these estimates.

         INVESTMENT VALUATION. Investments in mutual funds (the "Funds") are
valued at the net asset (market) value per share at the close of each business
day as reported by each Fund.

         INVESTMENT TRANSACTIONS. Investment transactions are accounted for on
the trade date. Realized gains and losses on investments are determined on the
basis of identified cost. Capital gain distributions from mutual funds are
recorded on the ex-dividend date and reinvested upon receipt.

         INVESTMENT INCOME. Dividend income from mutual funds is recorded on
the ex-dividend date and reinvested upon receipt.

         ANNUITY RESERVES. Net purchase payments made by variable annuity
contract owners are accumulated based on the performance of the investments of
the Separate Account until the date the contract owners select to commence
annuity payments. Reserves for annuities on which benefits are currently payable
are provided for based upon estimated mortality and other assumptions, including
provisions for the risk of adverse deviation from assumptions, which were
appropriate at the time the contracts were issued. The 1983(a) Individual
Mortality Table, the Annuity 2000 Mortality Table, and the 1994 Group Annuity
Reserve Mortality Table have been used in the computation of annuity reserves
for currently payable contracts. Participants are able to elect assumed
investment rates between 3.0% and 6.0%, as regulated by the applicable state
laws.

         ACCUMULATION UNITS. VALIC offers both standard and enhanced contracts.
These contracts may have different Separate Account charges.

NOTE C -- TRANSACTIONS WITH AFFILIATES

         VALIC serves as investment advisor ("the Advisor"), transfer agent, and
accounting services agent to AGSPC and AGSPC 3. American General Investment
Management, LLP, an affiliate of the Advisor, serves as investment sub-advisor
to certain AGSPC 3 mutual funds.

         The Separate Account is charged for mortality and expense risks
assumed by VALIC and for distribution and administrative services provided by
VALIC. The standard charge, based on the daily net assets of each division, is
assessed daily based on the following annual rates: for Division 10B, 0.85% on
the first $10,000,000, 0.425% on the next $90,000,000, and 0.21% on the excess
over $100,000,000; for Divisions 1,2,4 through 8, 10A, 10C and 10D, 11 through
17, 33 through 44, 48 through 50, and 58 through 60, 1.00%; and for Divisions
18 through 32, and 51 through 54, 1.25%. Certain mutual funds reimburse to
VALIC a portion of the distribution or administrative costs associated with
offering their funds through a VALIC annuity contract. VALIC, in turn reduces
the Separate Account charge to that division by the amount of the
reimbursement. The expense reduction is credited daily based on the following
annual rates: for Divisions 21 through 23, 26 through 30, 32 through 44, 48
through 50, and 58 through 60, 0.25%; for Division 31, 0.24% (effective
December 8, 1997, the expense reduction for Division 31 became 0.20% on the
first $75,000,000, and 0.25% on the excess over $75,000,000); and for Division
18, 0.15% (commencing July 1, 1997). Separate Account charges may be reduced if
contracts are issued to certain types of plans that are expected to result in
lower costs to VALIC. Consequently, each division may offer separate "classes"
of units of beneficial interest reflecting reductions in separate account
charges.

         Pursuant to the reorganization agreement entered into on April 17,
1987, which transferred VALIC Separate Accounts One and Two into Separate
Account A Divisions 10A and 10B, respectively, expenses of each division (as
defined to include underlying mutual fund expenses) are limited to the
following rates based on average daily net assets: Division 10A, 1.4157% on the
first $359,065,787, 1.36% on the next $40,934,213, and 1.32% on the excess over
$400,000,000; Division 10B, 0.6966% on the first $25,434,267, 0.5% on the next
$74,565,733, and 0.25% on the excess over $100,000,000. Accordingly, during the
years ended December 31, 1998 and 1997, VALIC reduced expenses of Division 10B
by $82,027 and $85,996, respectively.

         A portion of the annual contract maintenance charge is assessed on
each contract (except those relating to Divisions 10A and 10B) by VALIC on the
last day of the calendar quarter in which VALIC receives the first purchase
payment, and in quarterly installments thereafter during the accumulation
period. Maintenance charges assessed totaled $5,575,601 and $4,510,903 for the
years ended December 31, 1998 and 1997, respectively.

         VALIC received surrender charges of $4,581,641 and $2,769,370 for the
years ended December 31, 1998 and 1997, respectively. In addition, VALIC
received $53,171 and $6,156 for the year ended December 31, 1998, in sales load
on variable annuity purchase payments for Divisions 10A and 10B, respectively.
VALIC received $63,727 and $7,426 for the year ended December 31, 1997, in
sales load on variable annuity purchase payments for Divisions 10A and 10B,
respectively.

         VALIC contributed to the Separate Account, $100,000 and $74,900,000 on
August 26, 1998 and September 1, 1998, respectively, in order to provide
initial funding for the AGSPC 3 mutual funds. Capital surplus amounts reflected
in the Statements of Net Assets for Divisions 33 through 44, 48 through 50 and
58 through 60 are not subject to contract holder charges since they do not
represent reserves for annuity contracts issued.

NOTE E -- FEDERAL INCOME TAXES

         VALIC is taxed as a life insurance company under the Internal Revenue
Code and includes the operations of the Separate Account in determining its
federal income tax liability. Under current federal income tax law, the
investment income and capital gains from sales of investments realized by the
Separate Account are not taxable. Therefore, no federal income tax provision
has been made.

NOTE G -- YEAR 2000 (UNAUDITED)

         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.

         In addition, the Separate Account 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, as
well as contingency plans for any identified risks or shortcomings, 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 December 31, 1998, VALIC has incurred and expensed $26.7
million (pretax) related to Year 2000 readiness, including $20.2 million
incurred in 1998.

         As of December 31, 1998, VALIC has completed the inventory,
assessment, testing, reprogramming and implementation phases of the plan with
respect to its critical systems. VALIC believes its comprehensive plan and
resource commitment will allow it to meet its Year 2000 objectives. However,
the Year 2000 issue remains complex and the risks, uncertainties, and
unforeseen circumstances associated with the Year 2000 issue could have a
material adverse impact on VALIC and the Separate Account.

                        REPORT OF INDEPENDENT AUDITORS                       39
================================================================================


TO THE BOARD OF THE VARIABLE ANNUITY LIFE INSURANCE COMPANY AND CONTRACT OWNERS
OF THE VARIABLE ANNUITY LIFE INSURANCE COMPANY SEPARATE ACCOUNT A

We have audited the accompanying statements of net assets of The Variable
Annuity Life Insurance Company Separate Account A ("the Separate Account") and
each of the divisions (1, 2, 4, 5, 6, 7, 8, 10A, 10B, 10C, 10D, 11 through 44
inclusive, 48 through 51 inclusive, and 58 through 60, inclusive) comprising
the Separate Account as of December 31, 1998. We have also audited the related
statements of operations for the year then ended and the statements of changes
in net assets for each of the two years in the period then ended of the
Separate Account and each of its divisions except for divisions 33 through 44
inclusive, divisions 48 through 50 inclusive, and divisions 58 through 60,
inclusive, for which we have audited the statements of operations and changes
in net assets for the period from August 26, 1998 (inception) to December 31,
1998, and for division 51 for which we have audited the statements of
operations and changes in net assets for the period from September 22, 1998
(inception) through December 31, 1998. These financial statements are the
responsibility of the Separate Account's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits 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 statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of December 31, 1998,
by correspondence with the transfer agents. 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 audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Separate Account and each
of the divisions comprising the Separate Account at December 31, 1998, and the
results of their operations and changes in their net assets for each of the
periods identified above, in conformity with generally accepted accounting
principles.

The Statement of Additional Information ("SAI") has been amended as described
below to reflect the availability of the AGSPC Asset Allocation Division Five
and the AGSPC Small Cap Index Division Fourteen as investment options under
Certain Contracts.
 
The following paragraph has been added as the first paragraph to the section of
the SAI entitled "Performance Compared to Market Indices."
 
    The performance of AGSPC Asset Allocation Division Five may be compared to a
    benchmark comprised of a weighted average of three market sectors in which
    the Division, through the AGSPC Asset Allocation Fund, will invest. The base
    allocation is: 55% in equity securities, 35% in intermediate or long-term
    debt securities and 10% in money market or short-term debt securities. The
    Division's actual asset allocation is determined daily by the Bankers Trust
    Asset Allocation Model. The performance of the equity securities sector of
    the Division may be compared to the S&P 500(R)** Index. The performance of
    the intermediate or long-term debt securities sector may be compared to the
    Merrill Lynch Corporate and Government Master Index. The Merrill Lynch
    Corporate and Government Master Index consists of an index of approximately
    5,000 corporate and government bond holdings. The average maturity of these
    corporate bond holdings is approximately 10 years. The performance of the
    money market or short-term debt securities sector may be compared to the
    Certificate of Deposit Primary Offering by New York City Banks, 30 Day
    Index.

The following paragraph replaces the sixth paragraph in the section of the SAI
entitled "Performance Compared to Market Indices."
 
    The performance of the AGSPC Small Cap Index Division Fourteen and the
    Putnam OTC & Emerging Growth Division Twenty-seven may be compared with the
    Russell 2000(R) Index ("Russell 2000").** The Russell 2000 was developed in
    1984 by the Frank Russell Company to track the stock market performance of
    small capitalization domestic stocks. The Russell 2000 is market weighted
    and consists of approximately 2000 stocks. Stocks included in the Russell
    2000 are chosen by the Frank Russell Company on the basis of their market
    size.

insurance company organized under the laws of the State of Texas and is engaged
primarily in the offering and issuance of fixed and variable retirement annuity
contracts and combinations thereof. The Company also is licensed to write life
insurance in all states (other than Connecticut) and the District of Columbia,
and annuities in all fifty states and the District of Columbia. The Company is

MARKETING INFORMATION
 
     The Company has targeted not-for-profit organizations as the central focus
of its marketing efforts for its Contracts. The Company has utilized as its
general marketing theme the concept that the Company is "America's Retirement
Plan Specialists." Specifically, the Company's marketing thrust is aimed at
individuals and groups associated with public and private schools, colleges and
universities, not-for-profit health care organizations, state and local
governments and other not-for-profit organizations.
 
   
     This marketing concept has proven to be successful. In the aggregate,
premium deposits to the Company have grown from $37,000 in 1956 to more than
$3.7 billion as of December 31, 1998. The number of aggregate participant
accounts has increased from 155,000 accounts in 1980 to more than 1,954,190
accounts as of December 31, 1998. The number of employer groups which have
purchased Contracts has increased by 178 percent in the past ten years to more
than 26,392 as of December 31, 1998. As of December 31, 1998, the Company was
ranked in the top 1 percent of all U.S. life insurance companies with regard to
asset size. As of December 31, 1998 the Company's assets totaled more than $39
billion.
    
 
     The Company's growth can also be reviewed by examining each market segment
the Company targets.
 
   
     As of December 31, 1998, the Company was marketing Contracts in more than
10,218 public and private, primary and secondary schools with more than 494,584
participant accounts for employees in public and private schools nationwide.
From December 31, 1988 to December 31, 1998, the cash value of investments in
these Contracts has increased by 269 percent while the number of public and
private school groups in these Contracts increased 97 percent and the number of
participant accounts in these Contracts increased by 111 percent.
    
 
   
     The Company has also increased its marketing efforts to colleges and
universities. From December 31, 1988 to December 31, 1998, the number of
colleges and universities which allow the Company to market Contracts to its
faculty and staff members has increased 166 percent and for the same period the
number of participant accounts has increased 131 percent. For the same time
period cash values for participants have increased 306 percent. As of December
31, 1998, more than 33 percent of United States colleges and universities allow
the Company to market Contracts to their faculty and staff members.
    
 
     The Company has utilized as the central focus in its marketing to college
and university faculty and staff members the theme that the Company is the
"Alternative of Choice."
 
   
     The Company has also had growth in the health care segment of the
not-for-profit organization market. From December 31, 1988 to December 31, 1998
Contract cash values have increased 802 percent. During the same period the
number of health care groups that have purchased these Contracts increased 274
percent and the number of participant accounts increased 727 percent.
    
 
                                        4
<PAGE>   680
 
   
     The Company has also experienced growth in contracts sold to state and
local governmental groups. From December 31, 1988 to December 31, 1998, Contract
cash values for participants in these groups have increased 310 percent. For the
same period the number of participant accounts for individuals in these groups
in these Contracts increased 229 percent and the number of employer groups has
increased 303 percent.
    
 
   
     Additionally, several states have enacted, as an alternative to state
administered defined benefit retirement programs, Optional Retirement Plans
(ORPs). A state that sponsors an ORP will select the carriers which will be
allowed to participate in the ORP. The Company has been selected as one of the
carriers permitted to market Contracts to state employees who elect to
participate in the ORP in 26 of the last 29 states that sponsor ORPs as an
alternative to a state deferred, benefit plan and others multiple carriers, as
of December 31, 1998. From December 31, 1993 to December 31, 1998, in these ORPs
the number of participant accounts increased 81 percent and cash values
increased 153 percent to more than $2.7 billion dollars.
    
 
     The Company may, from time to time, refer to a general investment strategy
known as indexing. Several of the Divisions employ this investment strategy. The
Company may compare the performance of these Divisions to the S&P 500 Index, S&P
MidCap 400 Index, Russell 2000 Index, Morgan Stanley Capital International
Europe, Australia, and Far East (EAFE) Index, or any other appropriate market
index. The indexes are not managed funds and have no identifiable investment
objectives.
 
     The Company may, from time to time, refer, individually or collectively, to
its package of retirement plan services. Collectively, this package of services
may be referred to as easy Retirement Plan. Easy Retirement Planning includes:
(1) personal, face-to-face service from highly trained VALIC Retirement Plan
Specialists; (2) informative retirement-investment education programs, seminars
and materials; (3) specialized computer-aided services for retirement planning
and developing asset allocation strategies; (4) a wide selection of innovative,
market-responsive investment options; (5) advanced and efficient administration
of retirement accounts; and (6) a financially strong and stable Company with
which to do business.
 
   
     The Company may, from time to time, refer to the diversifying process of
asset allocation based on the Modern Portfolio Theory developed by Nobel
Prize-winning economist Harry Markowitz. The basic assumptions of Modern
Portfolio Theory are that the selection of individual investments has little
impact on portfolio performance, market timing strategies seldom work, markets
are efficient and selecting the suitable mix of asset classes is more important
when creating a long-term investment portfolio. Modern Portfolio Theory allows
an investor to determine an "efficient" or "optimized" portfolio that has
historically provided a higher return with the same risk or the same return with
lower risk.
    
 
   
     When presenting the asset allocation process the Company may outline the
process of personal and investment risk analysis including determining
individual risk tolerances and a discussion of the different types of investment
risk. The Company may classify investors into five categories based on their
personal risk tolerance and will quote various industry experts on which types
of investments are best suited to each of the five risk categories. The industry
experts quoted may include Ibbotson Associates, CDA Investment Technologies,
Lipper Analytical Services, Laffer-Cantos, Inc., The Variable Annuity Research &
Data Services ("VARDS") Report, Wilson Associates, Morningstar, Inc. and any
other expert which has been deemed by the Company to be appropriate. The Company
may also provide a historical overview of the performance of a variety of
investment market indexes and different asset categories, such as stocks, bonds,
cash equivalents, etc. The Company may also discuss investment volatility
(standard deviation) including the range of returns for different asset
categories and classes over different time horizons, and the correlation between
the returns of different asset categories and classes. The Company may also
discuss the basis of portfolio optimization including the required inputs and
the construction of efficient portfolios using sophisticated computer-based
techniques. Finally, the Company may describe various investment strategies and
methods of implementation such as the use of index funds vs. actively managed
funds, the use of dollar cost averaging techniques, the tax status of
contributions, and the periodic rebalancing of diversified portfolios.
    
 
     The Company, in its marketing efforts to each of the market segments, may
from time to time design sales literature and material specifically for
 
                                        5
<PAGE>   681
 
that market segment, e.g., the health care segment of the not-for-profit
organization market. This sales literature and material may also be specific to
a certain group. For example, sales literature and material may be designed for
a specific hospital. The sales literature and material would address
specifically the group's contract and retirement plan.

December 31, 1998, had more than $461 billion of assets under management.
    
 
   
     The Company may, from time to time, refer to the Wellington Management
Company, LLP (WMC) as investment adviser to the Vanguard Wellington Fund
(underlying Division Twenty-five) and the Vanguard Long-Term Corporate Fund
(underlying Division Twenty-two). WMC is a professional investment counseling
firm which globally provides investment services to investment companies,
institutions and individuals.
    
 
   
     The Company may, from time to time, refer to Vanguard Fixed Income Group
(VFIG) as investment adviser to the Vanguard Long-Term U.S. Treasury Fund
(underlying Division Twenty-three). VFIG provides investment advisory services
to more than 39 Vanguard money market and bond portfolios.
    
 
   
     The Company may, from time to time, refer to Barrow, Hanley, Mewhinney &
Strauss, Inc., Equinox Capital Management, Inc., Tukman Capital Management, Inc.
and Vanguard Core Management Group. Each is an investment adviser to Vanguard
Windsor II Fund (underlying Division Twenty-four). Barrow, Hanley, Mewhinney &
Strauss, Inc. is a Texas corporation which manages a portion of the equity
allocation of the Vanguard Windsor II. Equinox Capital Management, Inc., a
Delaware corporation, Tukman Capital Management, Inc., a Maryland corporation,
and Vanguard Core Management Group manage the investment and reinvestment of a
portion of the equity allocation of Vanguard Windsor II Fund.
    
 
   
     The Company may, from time to time, refer to Bankers Trust Company as
subadviser to American General Series Portfolio Company ("AGSPC") Stock Index
Fund (underlying Division 10); and T. Rowe Price Associates, Inc. as subadviser
to AGSPC Growth Fund (underlying Division 15) and AGSPC Science & Technology
Fund (underlying Division 17).
    
 
   
     Bankers Trust Company, subadviser to Division 10, is a wholly owned
subsidiary of Bankers Trust Corporation. On November 30, 1998, Bankers Trust
Corporation entered into an Agreement and Plan of Merger with Deutsche Bank AG
under which Bankers Trust Corporation and all of its subsidiaries would merge
with and into a subsidiary of Deutsche Bank AG. Deutsche Bank AG is a major
global banking institution that is engaged in a wide range of financial
services, including retail and commercial banking, investment banking and
insurance. The merger is contingent upon various regulatory approvals. On April
20, 1999, the AGSPC Fund's Board of Directors approved a new investment
sub-advisory agreement with Bankers Trust Company, subject to shareholder
approval. If the merger is approved and completed, Deutsche Bank AG, as the
Sub-Adviser's new parent company, will control the operations of the
Sub-Adviser. Bankers Trust believes that, under this new arrangement, the
services provided to the Fund will be maintained at their current level.
    
 
   
     On March 11, 1999, Bankers Trust announced that it had reached an agreement
with the United States Attorney's Office in the Southern District of New York to
resolve an investigation concerning inappropriate transfers of unclaimed funds
and related recordkeeping problems that occurred between 1994 and early 1996.
Pursuant to its agreement with the U.S. Attorney's Office, Bankers Trust pleaded
guilty to misstating entries in the bank's books and records and agreed to pay a
$60 million fine to federal authorities. Separately, Bankers Trust agreed to pay
a $3.5 million fine to the State of New York. The events leading up to the
guilty pleas did not arise out of the investment advisory or mutual fund
management activities of Bankers Trust or its affiliates.
    
 
   
     As a result of the plea, absent an order from the SEC, Bankers Trust would
not be able to continue to provide investment advisory services to the Fund. The
SEC has granted a temporary order to permit Bankers Trust and its affiliates to
continue
    
 
                                        7

to provide investment advisory services to registered investment companies.
There is no assurance that the SEC will grant a permanent order.
    
 
     The Company may, from time to time, refer in advertisements or sales
materials to certain milestones which are intended to emphasize the Company's
growth and development in assets, groups and various market segments. The
Company may also refer to other versions of Portfolio Director 2 in
advertisements or sales material. The Company may refer to certain innovative
aspects of its products such as having a variety of publicly available mutual
funds as Variable Account Options. Additionally the Company may refer from time
to time in advertisements or sales materials to marketing strategies it utilizes
to promote the Company's business objectives. Further, the Company may refer
from time to time in advertisements or sales materials to certain value-added
services it provides to its groups, Contract Owners and Participants.
 
     The Company may, from time to time, refer in its advertisements to Schwab
Personal Choice Retirement Accounts ("PCRA"). The PCRA is a self-directed
brokerage account that may be used by VALIC Participants to directly invest in
publicly available mutual funds. PCRA is marketed through the VALIC Investment
Services Company.
 
     The Company may from time to time compare the performance of the mutual
funds that serve as the investment vehicles for Portfolio Director 2 to the
performance of certain market indices. These market indices are described in the
"Performance Information" Section of this Statement of Additional Information.
 
ENDORSEMENTS AND
PUBLISHED RATINGS
 
     From time to time, in advertisements or in reports to Contract Owners, the
Company may refer to its endorsements. Endorsements are often in the form of a
list of organizations, individuals or other parties which recommend the Company
or the Contracts. The endorser's name will be used only with the endorser's
consent. It should be noted that the list of endorsements may change from time
to time.
 
     Also from time to time, the rating of the Company as an insurance company
by A. M. Best may be referred to in advertisements or in reports to Contract
Owners. Each year the A. M. Best Company reviews the financial status of
thousands of insurers, culminating in the assignment of Best's Ratings. These
ratings reflect their current opinion of the relative financial strength and
operating performance of an insurance company in comparison to the norms of the
life/health insurance industry. Best's Ratings range from A++ to F. An A++
rating means, in the opinion of A. M. Best, that the insurer has demonstrated
the strongest ability to meet its respective policyholder and other contractual
obligations.
 
     In addition, the claims-paying ability of the Company as measured by the
Standard and Poor's Ratings Group may be referred to in advertisements or in
reports to Contract Owners. A Standard and Poor's insurance claims-paying
ability rating is an assessment of an operating insurance company's financial
capacity to meet the obligations of its insurance policies in accordance with
their terms. Standard and Poor's ratings range from AAA to D.
 
     Further, from time to time the Company may refer to Moody's Investor's
Service's rating of the Company. Moody's Investor's Service's financial strength
ratings indicate an insurance company's ability to discharge senior policyholder
obligations and claims and are based on an analysis of the insurance company and
its relationship to its parent, subsidiaries and affiliates. Moody's Investor's
Service's ratings range from Aaa to C.
 
   
     The Company may additionally refer to its Duff & Phelp's rating. A Duff &
Phelp's rating is an assessment of a company's insurance claims paying ability.
Duff & Phelp's ratings range from AAA to CCC.
    
 
     Ratings relate to the claims paying ability of the Company's General
Account and not the investment characteristics of the Separate Account.
 
     The Company may from time to time, refer to Lipper Analytical Services
Incorporated ("Lipper"), Morningstar, Inc. ("Morningstar") and CDA/Wiesenberger
Investment Companies (CDA/Wiesenberger) when discussing the performance of its
Divisions. Lipper, Morningstar and CDA/Wiesenberger are leading publishers of
statistical data about the investment company industry in the United States.
 
     Additionally, the Company may compare the performance of the Divisions to
categories published by Lipper and Morningstar. Morningstar has not, however,
ranked the Neuberger&Berman Guardian Trust. The published categories which
 
                                        8
<PAGE>   684
 
may be utilized in comparison with the performance of the Divisions include the
Morningstar Growth and Income Mutual Fund Category, Morningstar Aggressive
Growth Mutual Fund Category, Morningstar Growth Mutual Fund Category,
Morningstar International Stock Mutual Fund Category, Lipper Growth and Income
Mutual Fund Category, Lipper Small Company Growth Mutual Fund Category, Lipper
Growth Mutual Fund Category and Lipper International Mutual Fund Category.
Additional Lipper or Morningstar categories may be utilized if they are deemed
by the Company relevant to the performance of the Company's Divisions.
 
   
     The Company may, from time to time, refer to the VARDS Report. The VARDS
Report offers monthly analysis of the variable annuity industry, including
marketing and performance information.
    
 
     Finally the Company will utilize as a comparative measure for the
performance of its Funds the Consumer Price Index ("CPI"). The CPI is a measure
of change in consumer prices, as determined in a monthly survey of the U.S.
Bureau of Labor Statistics. Housing costs, transportation, food, electricity,
changes in taxes and labor costs are among the CPI components. The CPI provides
a tool for determining the impact of inflation on an individual's purchasing
power.
 
TYPES OF VARIABLE ANNUITY
CONTRACTS
 
   
     Flexible payment deferred annuity Contracts are offered in connection with
the prospectus to which this Statement of Additional Information relates.
    
 
   
     Under flexible payment Contracts, Purchase Payments generally are made
until retirement age is reached. However, no Purchase Payments are required to
be made after the first payment. Purchase Payments are subject to any minimum
payment requirements under the Contract.
    
 
     Under deferred annuity contracts, Purchase Payments are invested and
accumulate on a fixed or variable basis until the date the Contract Owner
selects to commence annuity payments.
 
     The Contracts are non-participating and will not share in any of the
profits of the Company.
 
FEDERAL TAX MATTERS
 
     This Section summarizes the major tax consequences of contributions,
payments, and withdrawals under Portfolio Director 2, during life and at death.
 
     It is the opinion of VALIC and its tax counsel that a Qualified Contract
described in Section 403(a), 403(b), or 408(b) of the Code does not lose its
deferred tax treatment if Purchase Payments under the contract are invested in
publicly available mutual funds. If investment in publicly available mutual
funds were to cause the tax deferral provisions described below for these
specific types of contracts not to apply, you would be currently taxed on
transfers, redemptions, purchase payments and dividend and capital gains
distributions.
 
     In addition, it is also the opinion of VALIC and its tax counsel that, for
each other type of Qualified Contract, an independent exemption provides tax
deferral regardless of ownership of the Mutual Fund shares.
 
   
     For Non-Qualified Contracts, not all Variable Account Options are available
within your contract. Variable Account Options that are invested in Mutual Funds
available to the general public outside of annuity contracts or life insurance
contracts will be offered only to non-natural persons pursuant to the meaning of
Section 72 of the Code. In that case, investment earnings on contributions to
Non-Qualified Contracts generally will be taxed currently to the owner, and the
contracts will not be treated as annuities for federal income tax purposes.
    
 
TAX CONSEQUENCES OF PURCHASE PAYMENTS
 
     403(b) Annuities. Purchase Payments made by Section 501(c)(3) tax-exempt
organizations and public educational institutions toward Contracts for their
employees are excludable from the gross income of employees, to the extent
aggregate Purchase Payments do not exceed several competing tax limitations.
This gross income exclusion applies both to employer contributions and to your
voluntary and nonelective salary reduction contributions.
 
     Your voluntary salary reduction contributions are generally limited to
$10,000 ($9,500 before 1998), although additional, "catch-up" contributions are
permitted under certain circumstances. Combined employer and salary reduction
contribu-
 
                                        9
<PAGE>   685
 
tions are generally limited to the smallest of $30,000; approximately 25% of
salary; or an exclusion allowance which takes into account a number of factors.
In addition, after 1988 employer contributions for highly compensated employees
may be further limited by applicable nondiscrimination rules.
 
     401(a) and 403(a) Qualified Plans. Purchase Payments made by an employer
(or a self-employed individual) under a qualified pension, profit-sharing or
annuity plan are excluded from the gross income of the employee. Purchase
Payments made by an employee generally are made on an after-tax basis, unless
eligible for pre-tax treatment by reason of Sections 401(k) or 414(h).
 
   
     408(b) Individual Retirement Annuities ("408(b) IRAs"). Annual
tax-deductible contributions for 408(b) IRA Contracts are limited to the lesser
of $2,000 or 100% of compensation, and generally fully deductible only by
individuals who:
    
 
 (i) are not active participants in another retirement plan, and are not
     married;
 
 (ii) are not active participants in another retirement plan, are married, but
      either (a) the spouse is not an active participant in another retirement
      plan, or (b) the spouse is an active participant, but the couple's
      adjusted gross income does not exceed $150,000.
 
   
(iii) are active participants in another retirement plan, are unmarried, and
      have adjusted gross income of $31,000 or less ($30,000 for 1998, $25,000
      or less prior to 1998; adjusted upward for inflation after 1998); or
    
 
   
(iv) are active participants in another retirement plan, are married, and have
     adjusted gross income of $51,000 or less ($50,000 for 1998, $40,000 or less
     prior to 1998; adjusted upward for inflation after 1998).
    
 
     Active participants in other retirement plans whose adjusted gross income
exceeds the limits in (ii), (iii) or (iv) by less than $10,000 are entitled to
make deductible 408(b) IRA contributions in proportionately reduced amounts. If
a 408(b) IRA is established for a nonworking spouse who has no compensation, the
annual tax-deductible Purchase Payments for both spouses' Contracts cannot
exceed the lesser of $4,000 or 100% of the working spouse's earned income, and
no more than $2,000 may be contributed to either spouse's IRA for any year.
 
     You may be eligible to make nondeductible IRA contributions of an amount
equal to the excess of:
 
 (i) the lesser of $2,000 ($4,000 for you and your spouse's IRA) or 100% of
     compensation, over
 
(ii) your applicable IRA deduction limit.
 
     You may also make contributions of eligible rollover amounts from other
qualified plans and contracts. See Tax-Free Rollovers, Transfers and Exchanges.
 
     408A "Roth" Individual Retirement Annuities ("408A "Roth" IRAs"). After
1997, annual nondeductible contributions for 408A "Roth" IRA Contracts are
limited to the lesser of $2,000 or 100% of compensation, and may be made only by
individuals who:
 
 (i) are unmarried and have adjusted gross income of $95,000 or less; or
 
(ii) are married and filing jointly, and have adjusted gross income of $150,000
     or less.
 
The available nondeductible 408A "Roth" IRA contribution is reduced
proportionately to zero where adjusted gross income exceeds the limit in (i) by
$15,000 or less, or the limit in (ii) by $10,000 or less. Similarly, individuals
who are married and filing separately and whose adjusted gross income is less
than $15,000 may make a contribution to a Roth IRA of a portion of the otherwise
applicable $2,000 or 100% of compensation limit.
 
     All contributions to 408(b) IRAs, traditional nondeductible IRAs and 408A
"Roth" IRAs must be aggregated for purposes of the $2,000 annual contribution
limit.
 
     457 Plans. A unit of a state or local government may establish a deferred
compensation program for individuals who perform services for the government
unit. In addition, a non-governmental tax-exempt employer may establish an
eligible deferred compensation program for individuals who: (i) perform services
for the employer, and (ii) belong to a select group of management or highly
compensated employees and/or independent contractors.
 
   
     This type of program allows eligible individuals to defer the receipt of
compensation (and taxes thereon) otherwise presently payable to them. If the
program is an eligible deferred compensation plan (an "EDCP"), in 1999 you may
contribute (and
    
                                       10
<PAGE>   686
 
defer tax on) the lesser of $8,000 (indexed for inflation) or 33 1/3% of your
"includible" compensation (compensation from the employer currently includible
in taxable income). Additional, catch-up deferrals are permitted in the final
three years before the year you reach normal retirement age.
 
   
     The employer uses deferred amounts to purchase the Contracts offered by
this prospectus. For plans maintained by a unit of a state or local government,
the Contract is generally held for the exclusive benefit of plan participants,
although certain Contracts may remain subject to the claims of the employer's
general creditors until 1999. The employee has no present rights to any vested
interest in the Contract and is entitled to payment only in accordance with the
EDCP provisions.
    
 
   
     Simplified Employee Pension Plan ("SEP"). Employer contributions under a
SEP are made to a separate individual retirement account or annuity established
for each participating employee, and generally must be made at a rate
representing a uniform percent of participating employees' compensation.
Employer contributions are excludable from employees' taxable income, and after
1993 cannot exceed the lesser of $30,000 or 15% of your compensation.
    
 
   
     Through 1996, employees of certain small employers (other than tax-exempt
organizations) were permitted to establish plans allowing employees to
contribute pretax, on a salary reduction basis, to the SEP. In 1998 and 1999,
these salary reductions may not exceed $10,000 per year. This limit is indexed
and may be increased in future years. These salary reduction contributions may
not exceed $7,000, indexed for inflation in later years. Such plans if
established by December 31, 1996, may still allow employees to make these
contributions.
    
 
     SIMPLE IRA. Employer and employees contributions under a SIMPLE Retirement
Account Plan are made to a separate individual retirement account or annuity for
each employee. Employee salary reduction contributions cannot exceed $6,000 in
any year. Employer contributions can be a matching or a nonelective contribution
of a percentage as specified in the Code. Only employers with 100 or fewer
employees can maintain a SIMPLE IRA plan, which must also be the only plan the
employer maintains.
 
   
     Non-Qualified Contracts. Purchase Payments made under Non-Qualified
Contracts are neither excludible from the gross income of the Contract Owner nor
deductible for tax purposes. However, any increase in the Purchase Unit Value of
a Non-Qualified Contract resulting from the investment performance of VALIC
Separate Account A is not taxable to the Contract Owner until received by him.
Contract Owners that are not natural persons, however, are currently taxable on
any increase in the Purchase Unit Value attributable to Purchase Payments made
after February 28, 1986 to such Contracts.
    
 
TAX CONSEQUENCES OF DISTRIBUTIONS
 
     403(b) Annuities. Voluntary salary reduction amounts accumulated after
December 31, 1988, and earnings on voluntary contributions before and after that
date, may not be distributed before one of the following:
 
(1) attainment of age 59 1/2;
 
(2) separation from service;
 
(3) death;
 
(4) disability, or
 
(5) hardship (hardship distributions are limited to salary reduction
    contributions only, exclusive of earnings thereon).
 
     Similar restrictions will apply to all amounts transferred from a section
403(b)(7) custodial account other than rollover contributions.
 
     Distributions are taxed as ordinary income to the recipient in accordance
with Section 72.
 
     401(a) and 403(a) Qualified Plans. Distributions from Contracts purchased
under qualified plans are taxable as ordinary income, except to the extent
allocable to an employee's after-tax contributions (investment in the Contract).
If you or your Beneficiary receive a "lump sum distribution" (legally defined
term), the taxable portion may be subject to special 5-year or 10-year income
averaging treatment. Five-year forward averaging is unavailable for
distributions occurring after December 31, 1999. Ten-year income averaging uses
tax rates in effect for 1986, allows 20% capital gains treatment for the taxable
portion of a lump sum distribution attributable to years of service before 1974,
and is available if you were 50 or older on January 1, 1986.
 
                                       11
<PAGE>   687
 
     408(b) IRA, SEPs and SIMPLE IRAs. Distributions are generally taxed as
ordinary income to the recipient. Rollovers from an IRA to a Roth IRA, and
conversions of an IRA to a Roth IRA, where permitted, are generally taxable in
the year of the rollover or conversion. Such rollovers of conversions completed
in 1998 are generally eligible for pro-rata federal income taxation over four
years. Individuals with adjusted gross income over $100,000 are generally
ineligible for such conversions, regardless of marital status, as are married
individuals who file separately.
 
     408A "Roth" IRAs. "Qualified" distributions upon attainment of age 59 1/2,
upon death, disability or for first-time homebuyer expenses are tax-free as long
as five or more years have passed since the first contribution to taxpayer's
first 408A "Roth" IRA. A later date may apply to distributions from a Roth IRA
which contains one or more rollover contributions from a traditional IRA, to
determine if the distribution is qualified distribution. Qualified distributions
may be subject to state income tax in some states. Other distributions are
generally taxable to the extent that the distribution exceeds purchase payments.
 
   
     457 Plans. Amounts received from an EDCP are includible in gross income for
the taxable year in which they are paid or otherwise made available to the
recipient.
    
 
   
     Non-Qualified Contracts. Partial redemptions from a Non-Qualified Contract
purchased after August 13, 1982 (or allocated to post-August 13, 1982 Purchase
Payments under a pre-existing Contract), generally are taxed as ordinary income
to the extent of the accumulated income or gain under the Contract if they are
not received as an annuity. Partial redemptions from a Non-Qualified Contract
purchased before August 14, 1982 are taxed only after the Contract Owner has
received all of his pre-August 14, 1982 investment in the Contract. The amount
received in a complete redemption of a Non-Qualified Contract (regardless of the
date of purchase) will be taxed as ordinary income to the extent that it exceeds
the Contract Owner's investment in the Contract. Two or more Contracts purchased
from VALIC (or an affiliated company) by a Contract Owner within the same
calendar year, after October 21, 1998, are treated as a single Contract for
purposes of measuring the income on a partial redemption or complete surrender.
    
 
   
     When payments are received as an annuity, the Contract Owner's investment
in the Contract is treated as received ratably and excluded ratably from gross
income as a tax-free return of capital, over the expected payment period of the
annuity. Individuals who begin receiving annuity payments on or after January 1,
1987 can exclude from income only their unrecovered investment in the Contract.
Upon death prior to recovering tax-free their entire investment in the Contract,
such individuals generally are entitled to deduct the unrecovered amount on
their final tax return.
    
 
SPECIAL TAX CONSEQUENCES -- EARLY
DISTRIBUTION
 
     403(b) Annuities, 401(a) and 403(a) Qualified Plans, 408(b) IRAs, SEPs and
SIMPLE IRAs. Taxable distributions received before the recipient attains age
59 1/2 generally are subject to a 10% penalty tax in addition to regular income
tax. Distributions on account of the following generally are excepted from this
penalty tax:
 
(1) death;
 
(2) disability;
 
(3) separation from service after a participant reaches age 55 (only applies to
    403(b), 401(a), 403(a));
 
(4) separation from service at any age if the distribution is in the form of
    substantially equal periodic payments over the life (or life expectancy) of
    the Participant (or the Participant and Beneficiary), and
 
(5) distributions which do not exceed the employee's tax deductible medical
    expenses for the taxable year of receipt.
 
Separation from service is not required for distributions from an IRA, SEP or
SIMPLE IRA under #4 above. Certain distributions from a SIMPLE IRA within two
years after first participating in the plan may be subject to a 20% penalty,
rather than a 10% penalty.
 
   
Currently, distributions from 408(b) IRAs on account of the following additional
reasons are also excepted from this penalty tax:
    
 
(6) distributions up to $10,000 (in the aggregate) to cover costs of acquiring,
    constructing or reconstructing the residence of a first-time homebuyer, and
 
                                       12
<PAGE>   688
 
   
(7) distributions to cover certain costs of higher education: tuition, fees,
    books, supplies and equipment for the IRA owner, a spouse, child or
    grandchild, and
    
 
(8) distributions to cover certain medical care or long term care insurance
    premiums, for individuals who have received federal or state unemployment
    compensation for 12 consecutive months.
 
     408A "Roth" IRAs. Distributions, other than "qualified" distributions where
the five-year holding rule is met, are generally subject to the same 10% penalty
tax as other IRAs. Distributions of rollover or conversion contributions from an
IRA which are not qualified distributions, may be subject to additional penalty
taxes.
 
     457 Plans. Distributions generally may be made under an EDCP prior to
separation from service only for unforeseeable emergencies, or for amounts under
$5,000 for inactive Participants, and are includible in the recipient's gross
income in the year paid.
 
   
     Non-Qualified Contracts. A 10% penalty tax applies to the taxable portion
of a distribution received before age 59 1/2 under a Non-Qualified Contract,
unless the distribution is:
    
 
   
(1) to a Beneficiary on or after the Contract Owner's death;
    
 
   
(2) upon the Contract Owner's disability;
    
 
   
(3) part of a series of substantially equal annuity payments for the life or
    life expectancy of the Contract Owner, or the lives or joint life expectancy
    of the Contract Owner and Beneficiary;
    
 
   
(4) made under an immediate annuity contract, or
    
 
   
(5) allocable to Purchase Payments made before August 14, 1982.
    
 
SPECIAL TAX CONSEQUENCES -- REQUIRED
DISTRIBUTIONS
 
     403(b) Annuities. Generally, minimum required distributions must commence
no later than April 1 of the calendar year following the later of the calendar
year in which the Participant attains age 70 1/2 or the calendar year in which
the Participant retires. Required distributions must be made over a period that
does not exceed the life or life expectancies of the Participant (or lives or
joint life expectancies of the Participant and Beneficiary). The minimum amount
payable can be determined several different ways. A penalty tax of 50% is
imposed on the amount by which the minimum required distribution in any year
exceeds the amount actually distributed in that year.
 
     Amounts accumulated under a Contract on December 31, 1986 may be paid in a
manner that meets the above rule or, alternatively:
 
(i)  must begin to be paid when Participant attains age 75; and
 
(ii) the present value of payments expected to be made over the life of the
     Participant, (under the option chosen) must exceed 50% of the present value
     of all payments expected to be made (the "50% rule").
 
The 50% rule will not apply if a Participant's spouse is the joint annuitant.
Notwithstanding these pre-January 1, 1987 rules the entire contract balance must
meet the minimum distribution incidental benefit requirement of Section
403(b)(10).
 
     At the Participant's death before payout has begun, Contract amounts
generally either must be paid to the Beneficiary within 5 years, or must begin
within 1 year of death and be paid over the life or life expectancy of the
Beneficiary. If death occurs after commencement of (but before full) payout,
distributions generally must continue at least as rapidly as under the method
elected by the Participant and in effect at the time of death.
 
     A participant generally may aggregate his or her 403(b) contracts and
accounts for purposes of satisfying these requirements, and withdraw the
required distribution in any combination from such contracts or accounts, unless
the plan, contract, or account otherwise provides.
 
     401(a) and 403(a) Qualified Plans. Minimum distribution requirements for
Qualified Plans, are generally the same as described for 403(b) Annuities,
except that there is no exception for pre-1987 amounts, and multiple plans may
not be aggregated to satisfy the requirement.
 
     408(b) IRAs, SEPs and SIMPLE IRAs. Minimum distribution requirements are
generally the same as described above for 403(b) Annuities, except that:
 
(1) there is no exception for pre-1987 amounts; and
 
                                       13
<PAGE>   689
 
(2) there is no available postponement, past April 1 of the calendar year
    following the calendar year in which age 70 1/2 is attained.
 
     A participant generally may aggregate his or her IRAs for purposes of
satisfying these requirements, and withdraw the required distribution in any
combination from such contracts or accounts, unless the contract or account
otherwise provides.
 
     408A "Roth" IRAs. Minimum distribution requirements generally applicable to
403(b) Annuities, 401(a) and 403(a) Qualified Plans, 408(b) IRAs, SEPs and 457
Plans do not apply to 408A "Roth" IRAs during the owner's lifetime, but
generally do apply at the owner's death.
 
   
     A participant generally may aggregate his or her Roth IRAs inherited from
the same decedent for purposes of satisfying these requirements, and withdraw
the required distribution in any combination from such contracts or accounts,
unless the contract or account otherwise provides.
    
 
     457 Plans. Beginning January 1, 1989, the minimum distribution requirements
for EDCP's are generally the same as described above for 403(b) Annuities except
that there is no exception for pre-1987 amounts, and multiple plans may not be
aggregated to satisfy the requirement.
 
   
     Non-Qualified Contracts. Non-Qualified Contracts do not require
commencement of distributions at any particular time during the Owner's
lifetime, provided that the Owner is a natural person, and generally do not
limit the duration of annuity payments.
    
 
   
     At the Participant's death before payout has begun, Contract amounts
generally either must be paid to the Beneficiary within 5 years, or must begin
within 1 year of death and be paid over the life or life expectancy of the
Beneficiary. If death occurs after commencement of (but before full) payout,
distributions generally must continue at least as rapidly as under the method
elected by the Participant at the time of death.
    
 
TAX-FREE ROLLOVERS, TRANSFERS AND EXCHANGES
 
     403(b) Annuities. Tax free transfers between 403(b) annuity contracts
and/or 403(b)(7) custodial accounts, and tax-free rollovers from 403(b) programs
to 408(b) IRAs or other 403(b) programs, are permitted under certain
circumstances.
 
     401(a) and 403(a) Qualified Plans. The taxable portion of certain
distributions may be transferred in a tax-free rollover to a 408(b) individual
retirement account or annuity, or to another such plan.
 
   
     408(b) IRAs. Funds may be transferred tax-free to a 408(b) IRA Contract in
a tax-free rollover, from a 403(b) Annuity, or 401(a) or 403(a) Qualified Plan,
under certain conditions. These amounts may subsequently be rolled over on a
tax-free basis to another such plan or 403(b) Annuity Contract from this
"conduit" IRA. In addition, tax-free rollovers may be made from one 408(b) IRA
(other than a Roth IRA) to another provided that no more than one such rollover
is made during any twelve-month period.
    
 
     408A "Roth" IRAs. Funds may be transferred tax-free from one 408A "Roth"
IRA to another. Funds in a 408(b) IRA may be rolled in a taxable transaction to
a 408A "Roth" IRA by individuals who:
 
 (i) have adjusted gross income of $100,000 or less, whether single or married
     filing jointly;
 
(ii) are not married filing separately.
 
   
     Special, complicated rules governing holding periods, avoidance of the 10%
penalty tax and ratable recognition of 1998 income also apply to rollovers from
408(b) IRAs to 408A "Roth" IRAs, and may be subject to further modification by
Congress. You should consult your tax advisor regarding the application of these
rules.
    
 
     SEPs. Funds may be rolled over tax free from one SEP only to another SEP or
a 408(b) IRA.
 
     457 Plans. Tax-free transfer of EDCP amounts are permitted only to another
EDCP.
 
   
     Non-Qualified Contracts. Certain of the Non-Qualified single payment
deferred annuity Contracts permit the Contract Owner to exchange the Contract
for a new deferred annuity contract prior to the commencement of annuity
payments. The exchange of one annuity contract for another is a tax-free
transaction under Section 1035, but is reportable to the IRS.
    
 
EXCHANGE PRIVILEGE
 
     In the prospectus we described generally how under certain conditions we
will allow you to ex-
 
                                       14
<PAGE>   690
 
change from other fixed and/or variable contracts we issue (other contracts) to
Portfolio Director 2. These other contracts are listed in the prospectus. A more
detailed comparison of the features, charges and restrictions between each of
these listed other contracts and Portfolio Director 2 provided below.
 
     In the prospectus we also describe exchanges between Portfolio Director and
Portfolio Director 2, as well as among series of Portfolio Director 2, and the
restrictions imposed on those exchanges. Specifically once you have exchanged
between Portfolio Director and Portfolio 2 or among series of Portfolio Director
2 you must wait 120 days before making another exchange between Portfolio
Director and Portfolio Director 2.
 
   
EXCHANGES FROM PORTFOLIO DIRECTOR
    
 
  Sales/Surrender Charges.
 
     Portfolio Director and Portfolio Director 2 have the same provisions for
imposing surrender charges upon total or partial surrenders. Both Portfolio
Director and Portfolio Director 2 have the same provisions where surrender
charges are not imposed. For purposes of satisfying the fifteen-year and
five-year holding requirements described in "Surrender Charge" in the
prospectus, Portfolio Director 2 will be deemed to have been issued on the same
date as Portfolio Director. Purchase Payments exchanged into Portfolio Director
2 will be treated as Purchase Payments under Portfolio Director 2 for purposes
of calculating the surrender charge. Exchanged payments will be deemed to have
been made under Portfolio Director 2 on the date they were made to Portfolio
Director for purposes of calculating the surrender charge under Portfolio
Director 2.
 
  Other Charges
 
     Portfolio Director and Portfolio Director 2 have the same provisions for
imposing the quarterly account maintenance fee.
 
     Both Portfolio Director and Portfolio Director 2 impose an additional daily
charge with an annualized rate of 1.00% to 1.25% (or lower amounts during the
Purchase Period for different series of Portfolio Director 2), depending upon
the Variable Account Option selected, if any, on the daily net asset value of
VALIC Separate Account A. This charge is to cover expenses not covered by the
account maintenance fee and to compensate the Company for assuming mortality and
expense risks and administration expenses. Under Portfolio Director 2 the
Company will reimburse to certain Divisions any fees it receives from a Mutual
Fund for providing the Mutual Fund administrative and shareholder services.
 
  Investment Options
 
     Under Portfolio Director, sixteen divisions of VALIC Separate Account A are
available, thirteen of which invest in different investment portfolios of AGSPC
and three divisions of which invest in other mutual fund portfolios. These
mutual fund portfolios are managed either by the Company, the Dreyfus
Corporation or Templeton Investment Counsel Inc. for advisory fees at annual
rates ranging from .28% to .90% of each portfolio's or mutual fund's average
daily net assets. Two fixed investment options are also available.
 
     Under Portfolio Director 2, eighteen divisions of VALIC Separate Account A
are available, 6 of which invest in a different portfolio of AGSPC and 12
divisions of which invest in other publicly available mutual fund portfolios.
These mutual fund portfolios are managed either by the Company or other
investment managers for advisory fees ranging from 0.01% to 1.00% of each
portfolio's or mutual fund's average daily net assets. Two fixed investment
options are also available.
 
  Annuity Options
 
     Both Portfolio Director and Portfolio Director 2 provide the same annuity
options.
 
EXCHANGES FROM INDEPENDENCE PLUS CONTRACTS
 
     Sales/Surrender Charges. Under an Independence Plus Contract, no sales
charge is deducted at the time a Purchase Payment is made, but a surrender
charge may be imposed on partial or total surrenders. The surrender charge may
not exceed 5% of any Purchase Payments withdrawn within five years of the date
such Purchase Payments were made. The most recent Purchase Payments are deemed
to be withdrawn first. Up to 10% of the Account Value may be surrendered in a
Participant Year without any surrender charge being imposed. Portfolio Director
2 imposes a similar surrender charge upon total or partial surrenders. Both the
Portfolio Director 2 and Independence Plus Contracts have other similar
provisions where surrender charges are not imposed. However, Portfolio Director
2 provides at least one additional provision, not
 
                                       15
<PAGE>   691
 
included in Independence Plus Contracts, under which no surrender charge will be
imposed. An additional provision allows election of a systematic withdrawal
method without surrender charges. (See "Surrender Charge" in the prospectus.)
For purposes of satisfying the fifteen-year and five-year holding requirements
described under "Surrender Charge" in the prospectus, Portfolio Director 2 will
be deemed to have been issued on the same date as the Independence Plus Contract
or certificate thereunder, but no earlier than January 1, 1982. Purchase
Payments exchanged into Portfolio Director 2 and which were made within five
years before the date of exchange will be treated as Purchase Payments under
Portfolio Director 2 for purposes of calculating the surrender charge. Exchanged
payments will be deemed to have been made under Portfolio Director 2 on the date
they were made to Independence Plus Contracts for purposes of calculating the
surrender charge under Portfolio Director 2.
 
     Other Charges. Under the Independence Plus Contracts, a maintenance charge
of $20 is assessed for the first year and an annual charge of $15 is assessed
for the second and later years during the accumulation period. The charge is due
in quarterly installments. A daily fee is charged at the annual rate of 1% of
the daily net asset value allocable to the Variable Subaccounts to cover
administrative expenses (other than those covered by the annual charge) and
mortality risks assumed by the Company. For Portfolio Director 2, a quarterly
account maintenance fee of $3.75 is assessed for each calendar quarter during
the Purchase Period during which any Variable Account Option Account Value is
credited to a Participant's Account. The fee is to reimburse the Company for
some of the administrative expenses associated with the Variable Account
Options. No fee is assessed for any calendar quarter if the Account Value is
credited only to the Fixed Account Options throughout the quarter. Such fee
begins immediately if an exchange is made into any Variable Account Option
offered under Portfolio Director 2. The fee may also be reduced or waived by the
Company for Portfolio Director 2 if the administrative expenses are expected to
be lower for that Contract. (See "Reduction or Waiver of Account Maintenance
Fee, Surrender, Mortality and Expense Risk Fee or Administration and
Distribution Fee Charges" in the prospectus). To cover expenses not covered by
the account maintenance fee and to compensate the Company for assuming mortality
risks and administration and distribution expenses under Portfolio Director 2,
an additional daily charge with an annualized rate of 1.00% to 1.25% (or lower
amounts during the Purchase Period for different series of Portfolio Director
2), depending upon the Variable Account Options selected, if any, on the daily
net asset value of VALIC Separate Account A is attributable to Portfolio
Director 2. (See "Separate Account Charges" and "Separate Account Expense
Reimbursement" in the prospectus.)
 
     Investment Options. Under Independence Plus Contracts ten divisions of
VALIC Separate Account A are available variable investment alternatives, each
investing in shares of a different underlying fund of AGSPC portfolio. The ten
mutual funds are managed by the Company for advisory fees at annual rates
ranging from .28% to .50% of each respective portfolio's average daily net
assets. In addition, two fixed investment options are available. Under Portfolio
Director 2, eighteen divisions of VALIC Separate Account A are available, six of
which invest in a different investment portfolio of AGSPC and twelve divisions
of which invest in other publicly available mutual fund portfolios. These mutual
fund portfolios are managed either by the Company, or other investment advisers
for advisory fees at annual rates ranging from .01% to 1.00% of each portfolio's
or mutual fund's average daily net assets. Two fixed investment options are also
available.
 
     Annuity Options. Annuity options under Independence Plus Contracts provide
for payments on a fixed or variable basis, or a combination of both. The
Independence Plus Contract permits annuity payments for a designated period
between 3 and 30 years on a fixed basis only. Portfolio Director 2 permits
annuity payments for a designated period between of 5 and 30 years on a fixed
basis only. Independence Plus Contracts and Portfolio Director 2 both provide
for "betterment of rates." Under this provision, annuity payments for fixed
annuities will be based on mortality tables then being used by the Company, if
more favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM V-PLAN CONTRACTS
 
     Sales/Surrender Charges. Under a V-Plan Contract, no sales charge is
deducted at the time a Purchase Payment is made, but a surrender charge may be
imposed on partial or total surrenders. The surrender charge is equal to 7% of
the Purchase
 
                                       16
<PAGE>   692
 
Payments withdrawn within five years of the date such Purchase Payments were
made. The most recent Purchase Payments are deemed to be withdrawn first. Up to
10% of the account value may be surrendered in a Participant Year without any
surrender charge being imposed. Portfolio Director 2 also imposes a surrender
charge upon total or partial surrenders. However, the surrender charge under
Portfolio Director 2 may not exceed 5% of any Purchase Payments withdrawn within
the most recent five years prior to the receipt of the surrender request by the
Company at its Home Office. V-Plan Contracts have other provisions where
surrender charges are not imposed. However, Portfolio Director 2 provides at
least two additional provisions, not included in V-Plan Contracts, under which
no surrender charge will be imposed. Those Portfolio Director 2 provisions
include no surrender charge on an election of the no charge systematic
withdrawal method, and where an employee-participant has maintained the account
for a period of five years and has attained the age 59 1/2. (See "Surrender
Charge" in the prospectus.) For purposes of satisfying the fifteen-year and
five-year holding requirements, Portfolio Director 2 will be deemed to have been
issued on the same date as the V-Plan Contract or certificate thereunder, but no
earlier than January 1, 1982.
 
     If there is a total or partial surrender, Purchase Payments exchanged into
Portfolio Directors 2 and which were made within five years before the date of
exchange will be treated as Purchase Payments under Portfolio Director 2 for
purposes of calculating the surrender charge. Exchanged payments will be deemed
to have been made under Portfolio Director 2 on the date they were made to the
V-Plan Contract for purposes of calculating the surrender charge under Portfolio
Director 2.
 
     Other Charges. There are no administrative and risk charges under V-Plan
Contracts. For Portfolio Director 2, a quarterly account maintenance fee of
$3.75 is assessed for each calendar quarter during the Purchase Period during
which any Variable Account Option Account Value is credited to a Participant's
Account. The fee is to reimburse the Company for some of the administrative
expenses associated with the Variable Account Options. No fee is assessed for
any calendar quarter if the Account Value is credited only to the Fixed Account
Options throughout the quarter. Such fees begin immediately if an exchange is
made into any Variable Account Option offered under Portfolio Director 2. The
fee may also be reduced or waived by the Company on Portfolio Director 2 if the
administrative expenses are expected to be lower for that Contract. (See
"Reduction or Waiver of Account Maintenance Fee, Surrender, Mortality and
Expense Risk Fee or Administration and Distribution Fee Charges" in the
prospectus.) To cover expenses not covered by the account maintenance fee and to
compensate the Company for assuming mortality risks and administration and
distribution expenses under Portfolio Director 2, an additional daily charge
with an annualized rate of 1.00% to 1.25% (or lower amounts during the Purchase
Period for different series of Portfolio Director 2), depending upon the
Variable Account Options selected, if any, on the daily net asset value of the
VALIC Separate Account A is attributable to Portfolio Director 2. (See "Separate
Account Charges" and "Separate Account Expense Reimbursement" in the
prospectus.)
 
     Investment Options. There are no variable investment alternatives provided
under V-Plan Contracts.
 
     Annuity Options. Annuity options under V-Plan Contracts provide for
payments on a fixed basis only. The V-Plan Contract permits annuity payments for
a designated period of 1 to 15 years. Under a V-Plan Contract, the designated
period option may, subject to adverse tax consequences, be commuted at any time
for its remaining value. Portfolio Director 2 permits Payout Payments for a
designated period of between 5 and 30 years on a fixed basis only. Under
Portfolio Director 2, Payout Payments may be made on a fixed or variable basis,
or a combination of both. Portfolio Director 2 does not provide for commutation.
V-Plan Contracts and Portfolio Directors 2 both provide for "betterment of
rates." Under this provision, Payout Payments for fixed annuities will be based
on mortality tables then being used by the Company, if more favorable to the
Annuitant than those included in the Contract.
 
EXCHANGES FROM SA-1 AND SA-2 CONTRACTS (GUP-64, GUP-74, GTS VA CONTRACTS)
 
     Sales/Surrender Charges. Under the SA-1 and SA-2 Contracts a sales and
administrative charge is deducted from each Purchase Payment. This charge ranges
from 5% of the first $5,000 of Purchase Payments to 3% of Purchase Payments in
excess of $15,000. If a SA-1 or SA-2 Contract is
                                       17
<PAGE>   693
 
exchanged for Portfolio Director 2 the surrender charge under Portfolio Director
2 will not apply to the amount of Account Value applied to Portfolio Director 2
("Exchanged Amount"). Purchase Payments made to Portfolio Director 2, however,
would be subject to a surrender charge. In the case of a partial surrender, all
Purchase Payments to Portfolio Director 2 will be deemed to be withdrawn before
any Exchanged Amount is deemed to be withdrawn. No exchange pursuant to this
offer will be allowed within 120 days of a transfer of fixed accumulations under
a SA-1 or SA-2 Contract to the variable portion of such Contract. Under
Portfolio Director 2, no sales charge is deducted at the time a Purchase Payment
is made, but a surrender charge may be imposed on partial or total surrenders.
The surrender charge may not exceed 5% of any Purchase Payments withdrawn within
the most recent five years prior to the receipt of the surrender request by the
Company at its Home Office. For purposes of this surrender charge, the most
recent Purchase Payments are deemed to be withdrawn first. (See "Surrender
Charge" in the prospectus.)
 
     Other Charges. A charge of a percentage of each Purchase Payment is made
for administrative expenses for SA-1 and SA-2 Contracts. The charge is generally
1.25% and is included in the above sales and administrative charge. An
additional daily charge (at an annual rate of 1% of total net assets
attributable to SA-1 Contracts and ranging from .21% to .85% of total net assets
attributable to SA-2 Contracts) is made for mortality and expense risks assumed
by the Company under the variable portion of the Contract. The total of these
expenses and other charges is limited to a maximum of the rate imposed on SA-1
and SA-2 Contracts on April 1, 1987. (See prospectus for SA-1 and SA-2 contracts
dated April 20, 1987.) For Portfolio Director 2, a quarterly account maintenance
fee of $3.75 is assessed for each calendar quarter during the Purchase Period
during which any Variable Account Option Account Value is credited to a
Participant's Account. The fee is to reimburse the Company for some of the
administrative expenses associated with the Variable Account Options. No fee is
assessed for any calendar quarter if the Account Value is credited only to the
Fixed Account Options throughout the quarter. Such fee begins immediately if an
exchange is made into any Variable Account Option offered under Portfolio
Director 2. The fee may also be reduced or waived by the Company on Portfolio
Director 2 if the administrative expenses are expected to be lower for that
Contract. (See "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
in the prospectus.) To cover expenses not covered by the account maintenance fee
and to compensate the Company for assuming mortality risks and administration
and distribution expenses under Portfolio Director 2, an additional daily charge
with an annualized rate of 1.00% to 1.25% (or lower amounts during the Purchase
Period for different series of Portfolio Director 2), depending upon the
Variable Account Options selected, if any, on the average daily net asset value
of the Separate Account is attributable to Portfolio Director 2. (See "Separate
Account Charges" and "Separate Account Expense Reimbursement" in the
prospectus.)
 
     Investment Options. Under SA-1 and SA-2 Contracts only one division of
VALIC Separate Account A is available as a variable investment alternative. This
division invests in a portfolio of AGSPC. This portfolio is managed by the
Company for advisory fees at an annual rate of .28% of the portfolio's average
daily net assets. (Under a "grandfathering" arrangement, the total advisory fees
and certain other charges imposed against these Contracts are limited to a
maximum of the rate charged on April 1, 1987. See the prospectus for these
Contracts dated April 20, 1987.) Under Portfolio Director 2, eighteen divisions
of VALIC Separate Account A are available, six of which invest in a different
investment portfolio of AGSPC and twelve divisions of which invest in other
publicly available mutual fund portfolios. These mutual fund portfolios are
managed by either the Company or other investment managers, for advisory fees at
annual rates ranging from .01% to 1.00% of each portfolio's or mutual fund's
average daily net assets. Additionally, two fixed investment options are
available under Portfolio Director 2.
 
     Annuity Options. Annuity options under the SA-1 and SA-2 Contracts provide
for payments on a fixed or variable basis, or a combination of both. The SA-1
Contract annuity payments under a designated period option are limited to 15
years on a fixed basis only. Under this Contract, the designated period option
may, subject to adverse tax consequences, be commuted at any time for its
remaining value. SA-2 Contracts do not provide a designated period option nor do
they provide for commutation. Portfolio Director 2 permits Payout Payments for a
designated period of between 5 and 30 years on a
 
                                       18
<PAGE>   694
 
fixed basis only. Portfolio Director 2 does not provide for commutation. The
SA-1 and SA-2 Contracts make no provision for transfers from a separate account
to a fixed annuity during the annuity period. This option, subject to certain
conditions, is available under Portfolio Director 2. The SA-1 Contracts provide
an option for monthly variable annuity payments to be made at a level payment
basis during each year of the annuity period. Portfolio Director 2 does not
provide this option. SA-1 and Portfolio Director 2, but not SA-2 Contracts, both
provide for "betterment of rates." Under this provision, Payout Payments for
fixed annuities will be based on mortality tables then being used by the
Company, if more favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM IMPACT CONTRACTS
 
     Sales/Surrender Charges. Under an Impact Contract, no sales charge is
deducted at the time a Purchase Payment is made, but a surrender charge may be
imposed on partial or total surrenders. The surrender charge is equal to 5% of
the Purchase Payments withdrawn within three years of the date such Purchase
Payments were made. The most recent Purchase Payments are deemed to be withdrawn
first. Portfolio Director 2 also imposes a surrender charge upon total or
partial surrenders which may not exceed 5% of any Purchase Payments withdrawn
within the most recent five years prior to the receipt of the surrender request
by the Company at its Home Office. Portfolio Director 2 also has other
provisions where surrender charges are not imposed. (See "Exceptions to
Surrender Charge" in the prospectus.) For purposes of satisfying the
fifteen-year and five-year holding requirements, Portfolio Director 2 will be
deemed to have been issued on the same date as the Impact Contract, or
certificate thereunder, but no earlier than January 1, 1982. Only Purchase
Payments exchanged into a Portfolio Director 2 which were made within three
years before the date of exchange will be treated as Purchase Payments under
Portfolio Director 2 for purposes of calculating the surrender charge. Exchanged
payments will be deemed to have been made under Portfolio Director 2 on the date
they were made to Impact Contracts for purposes of calculating the surrender
charge under Portfolio Director 2.
 
     Other Charges. Under Impact Contracts, a $30 annual charge is assessed once
a year to cover administrative expenses. The charge may, with prior regulatory
approval if required, be increased or decreased. In addition, a daily charge is
made at an annual rate of 1% of the net asset value allocable to the Impact
Contracts to cover administrative expenses (other than those covered by the
annual charge) and mortality risks assumed by the Company. For Portfolio
Director 2, a quarterly account maintenance fee of $3.75 is assessed for each
calendar quarter during the Purchase Period during which any Variable Account
Option Account Value is credited to a Participant's Account. The fee is to
reimburse the Company for some of the administrative expenses associated with
the Variable Account Options. No fee is assessed for any calendar quarter if the
Account Value is credited only to the Fixed Account Options throughout the
quarter. Such fee begins immediately if an exchange is made into any Variable
Account Option offered under Portfolio Director 2. The fee may also be reduced
or waived by the Company on Portfolio Director 2 if the administrative expenses
are expected to be lower for that Contract. (See "Reduction or Waiver of Account
Maintenance Fee, Surrender, Mortality and Expense Risk Fee or Administration and
Distribution Fee Charges" in the prospectus.) To cover expenses not covered by
the account maintenance fee and to compensate the Company for assuming mortality
risks and administration and distribution expenses under Portfolio Director 2,
an additional daily charge with an annualized rate of 1.00% to 1.25% (or lower
amounts during the Purchase Period for different series of Portfolio Director
2), depending upon the Variable Account Options selected, if any, on the daily
net asset value of the Separate Account is attributable to Portfolio Director 2.
(See "Separate Account Charges" and "Separate Account Expense Reimbursement" in
the prospectus.)
 
     Investment Options. Under the Impact Contract five divisions of Separate
Account A are available as variable investment alternatives, each investing in
shares of a different underlying fund of AGSPC. The five mutual funds are
managed by the Company for advisory fees at annual rates ranging from .28% to
 .50% of each respective portfolio's average daily net assets. Under Portfolio
Director 2, eighteen divisions of VALIC Separate Account A are available, six of
which invest in a different investment portfolio of AGSPC and twelve divisions
of which invest in other publicly available mutual fund portfolios. These mutual
fund portfolios are managed by either the Company, or other invest-
                                       19
<PAGE>   695
 
ment managers, for advisory fees at annual rates ranging from .01% to 1.00% of
each portfolio's or mutual fund's average daily net assets. In addition, two
fixed investment options are available under Portfolio Director 2.
 
     Annuity Options. Annuity options under Impact Contracts provide for
payments on a fixed or variable basis, or a combination of both. The Impact
Contract permits annuity payments for a designated period of 1 to 15 years on a
fixed basis only. Under an Impact Contract, the designated period option may,
subject to adverse tax consequences, be commuted at any time for its remaining
value. Portfolio Director 2 permits Payout Payments for a designated period of
between 5 and 30 years on a fixed basis only. Portfolio Director 2 does not
provide for commutation. Impact Contracts and the Portfolio Director 2 both
provide for "betterment of rates." Under this provision, Payout Payments for
fixed annuities will be based on mortality tables then being used by the
Company, if more favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM COMPOUNDER CONTRACTS
 
     Sales/Surrender Charges. Under a Compounder Contract a sales and
administrative charge is deducted from each Purchase Payment. This charge ranges
from 5% of the first $5,000 of Purchase Payments to 3% of Purchase Payments in
excess of $15,000. If a Compounder Contract is exchanged for Portfolio Director
2 the surrender charge under Portfolio Director 2 will not apply to the amount
of Account Value applied to Portfolio Director 2. Purchase Payments made to
Portfolio Director 2, however, would be subject to the surrender charge under
Portfolio Director 2. In the case of a partial surrender, all Purchase Payments
to Portfolio Director 2 will be deemed to be withdrawn before any Exchanged
Amount is deemed to be withdrawn. Under Portfolio Director 2, no sales charge is
deducted at the time a Purchase Payment is made, but a surrender charge may be
imposed on partial or total surrenders. The surrender charge may not exceed 5%
of any Purchase Payments withdrawn within the most recent five years prior to
the receipt of the surrender request by the Company at its Home Office. For
purposes of this surrender charge, the most recent Purchase Payments are deemed
to be withdrawn first. (See "Surrender Charge" in the prospectus.)
 
     Other Charges. A charge of a percentage of each Purchase Payment is made
for administrative expenses under a Compounder Contract. The charge is 1.25% and
is included in the above sales charge. For Portfolio Director 2, a quarterly
account maintenance fee of $3.75 is assessed for each calendar quarter during
the Purchase Period during which any Variable Account Option Account Value is
credited to a Participant's Account. The fee is to reimburse the Company for
some of the administrative expenses associated with the Variable Account
Options. No fee is assessed for any calendar quarter if the Account Value is
credited only to the Fixed Account Options throughout the quarter. Such fee
begins immediately if an exchange is made into any Variable Account Option
offered under Portfolio Director 2. The fee may also be reduced or waived by the
Company for Portfolio Director 2 if the administrative expenses are expected to
be lower for that Contract. (See "Reduction or Waiver of Account Maintenance
Fee, Surrender, Mortality and Expense Risk Fee or Administration and
Distribution Fee Charges" in this prospectus.) To cover expenses not covered by
the account maintenance fee and to compensate the Company for assuming mortality
risks and administration and distribution expenses under Portfolio Director 2,
an additional daily charge with an annualized rate of 1.00% to 1.25% (or lower
amounts during the Purchase Period for different series of Portfolio Director
2), depending upon the Variable Account Options selected, if any, on the daily
net asset value of the Separate Account is attributable to Portfolio Director 2.
(See "Separate Account Charges" and "Separate Account Expense Reimbursement" in
the prospectus.)
 
     Investment Options. There are no variable investment alternatives provided
under Compounder Contracts.
 
     Annuity Options. Payout Payments under a Compounder Contract are on a fixed
basis only and the designated period option is limited to a period of 15 years.
However, under a Compounder Contract, the designated period option may, subject
to adverse tax consequences, be commuted at any time for its remaining value.
Portfolio Director 2 allows Payout Payments be made on a fixed or variable
basis, or both. One option under the Portfolio Director 2 provides for a
designated period of 5 and 30 years on a fixed basis only. Portfolio Director 2
does not provide for commutation. Unlike Portfolio Direc-

     Guaranteed Annuity Rates. Mortality rates have improved since annuity rates
were developed for the other contracts. Therefore, the annuity rates guaranteed
in Portfolio Director 2 are less favorable to Contract Owners and Annuitants
than those guaranteed in the other contracts. However, the current annuity rates
being charged for fixed annuities under the "betterment of rates" provisions
discussed above are more favorable than those guaranteed under Portfolio
Director 2 or the other contracts. Of course, no assurance can be given that
this will continue to be true at the time of annuitization for a given contract.
Guaranteed annuity rate tables are set forth in your Contract or in current
endorsements thereto. Those guaranteed for Portfolio Director 2 are set forth
therein, and copies may be obtained from one of the Company's Regional Offices
listed on the inside back cover of this prospectus.
 
     To satisfy a federal tax law requirement, non-spouse beneficiaries under
Portfolio Director 2 generally must receive the entire benefit payable upon the
death of the Annuitant over their life expectancy or within five years of the
Annuitant's death. This requirement may be inapplicable to certain other
contracts or certificates issued before January 19, 1985 if not exchanged.

     a. Since this is the first partial surrender in this participant year,
        calculate the excess over 10% of the value of the Purchase Units
 
       10% of $39,000 = $3,900 [no charge on this 10% withdrawal]
 
     b. The Account Value upon which Surrender Charge on the Full Surrender may
        be calculated (levied) is $39,000 - $3,900 = $35,100
 
     c. The Surrender Charge calculated on the Account Value withdrawn $35,100 X
        .05 = $1,755
 
     d. Since only $29,000 has been paid in Purchase Payments in the 60 months
        prior to the Full Surrender, the charge can only be calculated on
        $29,000. The $3,900 partial withdrawal does not reduce this amount.
        Thus, the charge is $29,000 X (0.05) = $1,450.

                   CALCULATION OF AVERAGE ANNUAL TOTAL RETURN
 
   
     Average Annual Total Return quotations for the 1, 3, 5, and 10 year periods
ended December 31, 1998, the date of the most recent balance sheet included in
this registration statement, are computed by finding the average annual
compounded rates of over the 1, 3, 5, and 10 year periods that would equate the
initial amount invested to the ending redeemable value, according to the
following formula:
    
 
                                 P (1+T)n = ERV

                 <S>     <C>
                 P     = a hypothetical initial Purchase Payment of $1,000

                 n     = number of years
                 ERV   = redeemable value at the end of the 1, 3, 5 or 10 year
                         periods of a hypothetical $1,000 Purchase Payment made at
                         the beginning of the 1, 3, 5, or 10 year periods (or
                         fractional portion thereof)

     The Company may advertise standardized average annual total return which,
includes the surrender charge of up to 5% of Gross Purchase Payments received
during the most recent 60 months as well as non-standardized average annual
total returns which does not include a surrender charge or maintenance fee.
 
     There is no sales charge for reinvested dividends. All recurring fees have
been deducted. For fees which vary with the account size, an account size equal
to that of the median account size has been assumed. Ending redeemable value has
been determined assuming a complete redemption at the end of the 1, 3, 5 or 10
year period and deduction of all nonrecurring charges at the end of each such
period.

PERFORMANCE INFORMATION
 
HYPOTHETICAL $10,000 ACCOUNT VALUE AND
CUMULATIVE RETURN AS COMPARED TO BENCHMARKS TABLES.
 
   
     The following tables show the Hypothetical $10,000 Account Value and
Cumulative Return for each Division as compared to the benchmarks shown. For
different series of Portfolio Director 2 which may have lower charges during the
purchase period those amounts shown in the following tables will be higher.
    
 
     These performance calculations for the Divisions, and the methods used for
calculating them, are explained in the prospectus. (See "How To Review
Investment Performance of Separate Account Divisions" and "Variable Account
Options" in the prospectus.)
 
     These tables compare hypothetical investment performance and percentage
changes in Purchase Unit values with the results of several benchmarks,
representing unmanaged market indices. The performance information has been
adjusted to reflect mortality and expense risk fees and administration and
distribution fees, net of any expense reimbursements from the Underlying Fund.
Surrender charges, maintenance fees and premium taxes are not deducted. The
effect of these charges is to reduce total return to a Contract Owner. The
comparisons should be considered in light of the investment policies and
objectives of the Funds. Rates of return for the Divisions include reinvestment
of investment income, including capital gains, interest and dividends. The rates
of return on the market indices also have been adjusted to reflect reinvestment
of interest and dividends.
 
     Price returns for the market indices are calculated by subtracting the
price level at the beginning of the year from the price level at the end of the
year and dividing the difference by the price level at the beginning of the
year. To calculate dollar values for the indices' Hypothetical $10,000 Account
Value presentation, price index values were substituted for Unit values in the
calculation described in the prospectus, and where applicable, dividend yields
were then added to determine the total returns applied in the dollar value
calculations. Similarly, to calculate Cumulative Return for the indices, the
Cumulative Return calculation described in the prospectus for Unit values of the
Divisions is used, substituting the Hypothetical $10,000 Account Value at the
end of each year for the Purchase Unit Value. No sales load, administrative
charges, or any other expenses have been deducted from the index calculations.
 
     Additionally, the performance of a Division may from time to time be
compared with other Indexes which have been deemed by the Company relevant to
the Division.
 
     These benchmarks do not reflect any charges for investment advisory fees,
brokerage commissions or other fees and expenses of the type charged at either
the Separate Account or Fund level. Therefore, the comparisons with these
benchmarks are of limited use.
 
     THE PERFORMANCE RESULTS SHOWN IN THIS SECTION ARE NOT AN ESTIMATE OR
GUARANTEE OF FUTURE INVESTMENT PERFORMANCE, AND DO NOT REPRESENT THE ACTUAL
EXPERIENCE OF AMOUNTS INVESTED BY A PARTICULAR PARTICIPANT.

                                PAYOUT PAYMENTS
 
ASSUMED INVESTMENT RATE
 
     The discussion concerning the amount of payout payments which follows this
section is based on an Assumed Investment Rate of 3 1/2% per annum. However, the
Company will permit each Annuitant choosing a variable payout option to select
an Assumed Investment Rate permitted by state law or regulations other than the
3 1/2% rate described in this prospectus as follows: 3%, 4 1/2%, 5% or 6% per
annum. (Note: an Assumed Investment Rate higher than 5% may not be selected
under individual Contracts.) The foregoing Assumed Investment Rates are used
merely in order to determine the first monthly payment per thousand dollars of
value. It should not be inferred that such rates will bear any relationship to
the actual net investment experience of VALIC Separate Account A.
 
AMOUNT OF PAYOUT PAYMENTS
 
     The amount of the first variable annuity payment to the Annuitant will
depend on the amount of the Account Value applied to effect the variable annuity
as of the tenth day immediately preceding the date payout payments commence, the
amount of any premium tax owed, the annuity option selected, and the age of the
Annuitant.
 
   
     The Contracts contain tables indicating the dollar amount of the first
payout payment under each payout option for each $1,000 of Account Value (after
the deduction for any premium tax) at various ages. These tables are based upon
the Annuity 2000 Table (promulgated by the Society of Actuaries) and an Assumed
Investment Rate of 3%, 3 1/2%, 4% and 5% per annum (3 1/2% in the group
Contract).
    
 
     The portion of the first monthly variable payout payment derived from a
Division of VALIC Separate Account A is divided by the Payout Unit value for
that Division (calculated ten days prior to the date of the first monthly
payment) to determine the number of Payout Units in each Division represented by
the payment. The number of such units will remain fixed during the Payout
Period, assuming the Annuitant makes no transfers of Payout Units to provide
Payout Units under another Division or to provide a fixed annuity.
 
     In any subsequent month, the dollar amount of the variable payout payment
derived from each Division is determined by multiplying the number of Payout
Units in that Division by the value of such Payout Unit on the tenth day
preceding the due date of such payment. The Payout Unit value will increase or
decrease in proportion to the net investment return of the Division or Divisions
underlying the variable payout since the date of the previous payout payment,
less an adjustment to neutralize the 3 1/2% or other Assumed Investment Rate
referred to above.
 
     Therefore, the dollar amount of variable payout payments after the first
will vary with the amount by which the net investment return is greater or less
than 3 1/2% per annum. For example, if a Division has a cumulative net
investment return of 5% over a one year period, the first payout payment in the
next year will be approximately 1 1/2 percentage points greater than the payment
on the same date in the preceding year, and subsequent payments will continue to
vary with the investment experience of the Division. If such net investment
return is 1% over a one year period, the first payout payment in the next year
will be approximately 2 1/2 percentage points less than the payment on the same
date in the preceding year, and subsequent payments will continue to vary with
the investment experience of the applicable Division.
 
     Each deferred Contract provides that, when fixed payout payments are to be
made under one of the first four payout options, the monthly payment to the
Annuitant will not be less than the monthly payment produced by the then current
settlement option rates, which will not be less than the rates used for a
currently issued single payment immediate annuity contract. The purpose of this
provision is to assure the Annuitant that, at retirement, if the fixed payout
purchase rates then required by the Company for new single payment immediate
annuity contracts are significantly more favorable than the annuity rates
guaranteed by a Contract, the Annuitant will be given the benefit of the new
annuity rates.
 
PAYOUT UNIT VALUE
 
     The value of a Payout Unit is calculated at the same time that the value of
an Purchase Unit is calculated and is based on the same values for Fund shares
and other assets and liabilities. (See "Purchase Period" in the prospectus.) The
calcula-

tion of Payout Unit value is discussed in the prospectus under "Payout Period."
 
     The following illustrations show, by use of hypothetical examples, the
method of determining the Payout Unit value and the amount of variable annuity
payments.

                   DISTRIBUTION OF VARIABLE ANNUITY CONTRACTS
 
     The Company has qualified or intends to qualify the Contracts for sale in
all fifty states and the District of Columbia and will commence offering the
Contracts promptly upon qualification in each such jurisdiction.
 
   
     The Contracts are sold in a continuous offering by licensed insurance
agents who are registered representatives of broker-dealers which are members of
the National Association of Securities Dealers, Inc. (the "NASD"). The principal
underwriter for VALIC Separate Account A is A.G. Distributors, an affiliate of
VALIC. A.G. Distributors' address is 2929 Allen Parkway, Houston, Texas 77019.
A.G. Distributors is a Delaware corporation organized in 1994 and is a member of
the NASD.
    
 
   
     The licensed agents who sell the Contracts will be compensated for such
sales by commissions ranging up to 6.0% of each Purchase Payment. Managers who
supervise the agents will receive overriding commissions ranging up to 1% of
Purchase Payments. These various commissions are paid by the Company and do not
result in any charge to Contract Owners or to VALIC Separate Account A in
addition to the charges described under "Fees and Charges" in the prospectus.
    
 
   
     Pursuant to its underwriting agreement with A.G. Distributors and VALIC
Separate Account A, the Company reimburses A.G. Distributors for reasonable
sales expenses, including overhead expenses. Prior to May 1, 1999, The Variable
Annuity Marketing Company (VAMCO) was the principal underwriter for VALIC
Separate account A. Sales commissions paid for the years 1996, 1997 and 1998
were $11,530,000, $46,521,000 and $63,212,594, respectively. VAMCO retained $0
in commissions for the years 1996, 1997 and 1998.

                   THE VARIABLE ANNUITY LIFE INSURANCE COMPANY
- --------------------------------------------------------------------------------
Report of Independent Auditors



To the Board of Directors
The Variable Annuity Life Insurance Company





         We have audited the accompanying consolidated balance sheets of The
Variable Annuity Life Insurance Company and Subsidiaries as of December 31, 1998
and 1997, and the related consolidated statements of income, changes in
stockholder's equity, comprehensive income, and cash flows for each of the three
years in the period ended December 31, 1998. These financial statements are the
responsibility of the company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

         We conducted our audits 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 statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. 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 audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of The
Variable Annuity Life Insurance Company and Subsidiaries at December 31, 1998
and 1997, and the consolidated results of their operations and their cash flows

                        SIGNIFICANT ACCOUNTING POLICIES

1.1  INTRODUCTION


     The Variable Annuity Life Insurance Company (VALIC), an indirect, wholly
owned subsidiary of American General Corporation (AGC), provides tax-deferred
retirement annuities and employer-sponsored retirement plans to employees of
educational, health care, public sector and not-for-profit organizations. VALIC
markets products nationwide through exclusive sales representatives.

     VALIC is 100% owned by American General Life Insurance Company (AGL), a
wholly owned subsidiary of AGC Life Insurance Company (AGC Life). AGC Life is a
wholly owned subsidiary of AGC. A summary of the accounting policies followed in
the preparation of the consolidated financial statements is set forth below.

1.2  PREPARATION OF FINANCIAL STATEMENTS

     The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles (GAAP) and include the accounts of
VALIC and its wholly owned subsidiaries. All material intercompany transactions
have been eliminated in consolidation.

     The preparation of financial statements requires management to make
estimates and assumptions that affect amounts reported in the financial
statements and disclosures of contingent assets and liabilities. Ultimate
results could differ from these estimates.

1.3  ACCOUNTING CHANGES

     COMPREHENSIVE INCOME. During 1998, VALIC adopted Statement of Financial
Accounting Standards (SFAS) 130, "Reporting Comprehensive Income," which
establishes standards for reporting and displaying comprehensive income and its
components in the financial statements. VALIC elected to report comprehensive
income and its components in a separate statement of comprehensive income.
Adoption of this statement did not change recognition or measurement of net
income and, therefore, did not impact VALIC's consolidated results of operations
or financial position.

     DERIVATIVES. In June 1998, the Financial Accounting Standards Board issued
SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," which
requires all derivative instruments to be recognized at fair value as either
assets or liabilities in the balance sheet. Changes in the fair value of a
derivative instrument are to be reported as earnings or other comprehensive
income, depending upon the intended use of the derivative instrument. This
statement is effective for years beginning after June 15, 1999. Adoption of SFAS
133 is not expected to have a material impact on VALIC's consolidated results of
operations or financial position.

1.4  INVESTMENTS

     FIXED MATURITY AND EQUITY SECURITIES. At year end, all fixed maturity and
equity securities are classified as available-for-sale and recorded at fair
value. After adjusting related balance sheet accounts as if the unrealized gains
(losses) had been realized, the net adjustment is recorded in accumulated other
comprehensive income within stockholder's equity. If the fair value of a
security classified as available-for-sale declines below its cost and this
decline is considered to be other than temporary, the security is reduced to its
fair value, and the reduction is recorded as a realized loss.

     During 1998, VALIC maintained a trading portfolio of certain fixed maturity
securities. Trading securities are recorded at fair value. Unrealized gains
(losses), as well as realized gains (losses), are included in net investment
income. VALIC held no trading securities at December 31, 1998, and trading
securities did not have a material effect on net investment income.

     MORTGAGE LOANS. Mortgage loans are reported at amortized cost, net of an
allowance for losses. The allowance for losses covers all non-performing loans
and loans for which management has a concern based on its assessment of risk
factors, such as potential non-payment or non-monetary default. The allowance is
based on a loan-specific review and a formula that reflects past results and
current trends.

     Loans for which VALIC determines that collection of all amounts due under
the contractual terms is not probable are considered to be impaired. VALIC
generally looks to the underlying collateral for repayment of impaired loans.
Therefore, impaired loans are considered to be collateral dependent and are
reported at the lower of amortized cost or fair value of the underlying
collateral, less estimated costs to sell.

     POLICY LOANS. Policy loans are reported at unpaid principal balance.

     INVESTMENT INCOME. Interest on fixed maturity securities and performing
mortgage loans is recorded as income when earned and is adjusted for any
amortization of premium or discount. Interest on delinquent mortgage loans is
recorded as income when received. Dividends are recorded as income on
ex-dividend dates.

     REALIZED INVESTMENT GAINS (LOSSES). Realized investment gains (losses) are
recognized using the specific identification method.

1.5  DERIVATIVES RELATED TO INVESTMENTS

     VALIC's use of derivative financial instruments is generally limited to
interest rate and currency swap agreements, and options to enter into interest
rate swap agreements (call swaptions). VALIC accounts for its derivative
financial instruments as hedges.

     INTEREST RATE AND CURRENCY SWAP AGREEMENTS. Interest rate swap agreements
are used to convert specific investment securities from a floating-rate to a
fixed-rate basis, or vice versa. Currency swap agreements are used to convert
cash flows from specific investment securities denominated in foreign currencies
into U.S. dollars at specified exchange rates, and to hedge against currency
rate fluctuations on anticipated security purchases.

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

1.5  DERIVATIVES RELATED TO INVESTMENTS-(CONTINUED)

     The difference between amounts paid and received on swap agreements is
recorded on an accrual basis as an adjustment to investment income over the
periods covered by the agreements. The related amount payable to or receivable
from counterparties is included in other liabilities or assets.

     The fair values of swap agreements are recognized in the consolidated
balance sheet if they hedge investments carried at fair value or if they hedge
anticipated purchases of such investments. In this event, changes in the fair
value of a swap agreement are reported in accumulated other comprehensive income
included in stockholder's equity, consistent with the treatment of the related
investment security.

     For swap agreements hedging anticipated investment purchases, the net swap
settlement amount or unrealized gain or loss is deferred and included in the
measurement of the anticipated transaction when it occurs.

     Swap agreements generally have terms of two to ten years. Any gain or loss
from early termination of a swap agreement is deferred and amortized into income
over the remaining term of the related investment. If the underlying investment
is extinguished or sold, any related gain or loss on swap agreements is
recognized in income.

     Swaptions. Options to enter into interest rate swap agreements are used to
limit VALIC's exposure to reduced spreads between investment yields and interest
crediting rates should interest rates decline significantly over prolonged
periods.

     During prolonged periods of decreasing interest rates, the spread between
investment yields and interest crediting rates may be reduced as a result of
minimum rate guarantees on certain insurance and annuity contracts, which limit
VALIC's ability to reduce interest crediting rates. Call swaptions, which allow
VALIC to enter into interest rate swap agreements to receive fixed rates and pay
lower floating rates, effectively maintain the spread between investment yields
and interest crediting rates during such periods.

     During prolonged periods of increasing interest rates, the spread between
investment yields and interest crediting rates may be reduced as a result of
VALIC's decision to increase interest crediting rates to limit surrenders. Put
swaptions, which allow VALIC to enter into interest rate swap agreements to pay
fixed rates and receive higher floating rates, effectively maintain the spread
between investment yields and interest crediting rates during such periods.

     Premiums paid to purchase swaptions are included in investments and are
amortized to net investment income over the exercise period of the swaptions. If
a swaption is terminated, any gain is deferred and amortized to insurance and
annuity benefits over the expected life of the insurance and annuity contracts
and any unamortized premium is charged to income. If a swaption ceases to be an
effective hedge, any gain or loss is recognized in income.

1.6  DEFERRED POLICY ACQUISITION COSTS (DPAC)

     Certain costs of writing an insurance policy, including commissions,
underwriting and marketing expenses, are deferred and reported as DPAC. DPAC is
charged to expense in relation to the estimated gross profits of the insurance
contracts, including realized gains (losses).

     DPAC is adjusted for the impact on estimated future gross profits as if net
unrealized gains (losses) on securities had been realized at the balance sheet
date. The impact of this adjustment is included in accumulated other
comprehensive income within stockholder's equity.

     VALIC reviews the carrying value of DPAC on at least an annual basis.
Management considers estimated future gross profit margins as well as expected
mortality, interest earned and credited rates, persistency, and expenses in
determining whether the carrying amount is recoverable.

1.7  SEPARATE ACCOUNTS

     Separate Accounts are assets and liabilities associated with certain
contracts, principally annuities for which the investment risk lies solely with
the holder of the contract rather than VALIC. Consequently, VALIC's liability
for these accounts equals the value of the account assets. Investment income,
realized investment gains (losses) and policyholder account deposits and
withdrawals related to Separate Accounts are excluded from the consolidated
statements of income and cash flows. Assets held in the Separate Accounts are
primarily shares in mutual funds, which are carried at fair value, based on the
quoted net asset value per share.

1.8  POLICY RESERVES

     Net deposits made by fixed annuity policyholders are accumulated at
interest rates guaranteed by VALIC plus excess interest credited at the sole
discretion of the Board of Directors until benefits are payable. Reserves for
deferred annuities (accumulation phase) are equivalent to the policyholders'
account values. Reserves for annuities on which benefits are currently payable
(annuity payout phase) are provided based upon estimated mortality and other
assumptions, including provisions for the risk of adverse deviation from
assumptions, which were appropriate at the time the contracts were issued. The
1971 Individual or Group Annuity Mortality Tables, and the 1983a Table have been
used to provide for future annuity benefits in the annuity payout phase.
Interest rates used in determining reserves for policy benefits during both the
accumulation and annuity payout phases range from 3.5% to 13.5%.

1.9  RECOGNITION OF REVENUES AND COSTS

     Premium receipts for annuity contracts are classified as deposits instead
of revenues. Revenues for these contracts consist of the mortality, expense and
surrender charges. Gains (losses) from mortality guarantees under variable
annuity contracts are recognized as they occur.

1.10 INCOME TAXES

     Deferred tax assets and liabilities are established for temporary
differences between the financial reporting basis and the tax basis of assets
and liabilities, at the enacted tax rates expected to be in effect when the
temporary differences reverse. The effect of a tax rate change is recognized in
income in the period of enactment. State income taxes are included in income tax
expense.

     A valuation allowance for deferred tax assets is provided if all or some
portion of the deferred tax asset may not be realized. An increase or decrease
in a valuation allowance that results from a change in circumstances that causes
a change in judgment about the realizability of the related deferred tax asset
is included in income. A change related to fluctuations in fair value of
available-for-sale fixed maturity securities is included in accumulated other
comprehensive income in stockholder's equity.

1.11 STATUTORY ACCOUNTING

     State insurance laws and regulations prescribe accounting practices for
calculating statutory net income and equity (capital and surplus) that differ
from GAAP. Net income and stockholder's equity as determined by statutory
accounting practices at December 31 were as follows:

1.12 COINSURANCE TRANSACTION

     On May 21, 1998, VALIC completed the acquisition of a block of individual
annuity business in a coinsurance transaction. This transaction increased assets
and insurance and annuity liabilities by $688,221.

     The carrying value of investments that produced no investment income during
1998 totaled $313 or 0.001% of total invested assets. The ultimate disposition
of these assets is not expected to have a material effect on VALIC's
consolidated results of operations or financial position.

     Derivative financial instruments related to investment securities did not
have a material effect on net investment income in any of the three years ended
December 31, 1998.

5.1  TAX-SHARING AGREEMENT

     VALIC, combined with its Separate Accounts, is taxed as a life insurance
company. VALIC and the Separate Accounts are included in the consolidated life
insurance company tax return of AGC. VALIC participates in a tax-sharing
agreement with the other companies included in the consolidated return. Under
this agreement, tax payments are made to AGC as if the companies filed separate
tax returns and companies incurring operating losses and/or capital losses are
reimbursed for the use of these losses by the consolidated return group.

5.2  TAX LIABILITIES

     Components of income tax liabilities and assets at December 31 were as

     Federal income taxes paid in 1998, 1997, and 1996 were $92,613, $106,338,

                                 CAPITAL STOCK

     VALIC has two classes of capital stock: preferred stock ($1.00 par value
with 2 million shares authorized) that may be issued with such dividend,
liquidation, redemption, conversion, voting and other rights as the Board of
Directors may determine, and common stock ($1.00 par value, 5 million shares
authorized).

     VALIC is restricted by state insurance laws as to the amount it may pay as
dividends without prior approval from the Texas Department of Insurance. The
maximum dividend payout which may be made without prior approval in 1999 is
$176,753.

                                    -----------      -----------
</TABLE>


     During 1998, VALIC purchased call swaptions and put swaptions that expire
by 2000. The call swaptions had a notional amount of $950,000 and strike rates
ranging from 3.5% to 4.5% at December 31, 1998. The put swaptions had a notional
amount of $690,000 strike rates ranging from 8.0% to 8.5% at December 31, 1998.
Should the strike rates remain below market rates for call swaptions and above
market rates for put swaptions, the swaptions will expire, and VALIC's exposure
would be limited to the premiums paid. These premiums were immaterial.

     CREDIT AND MARKET RISK. Derivative financial instruments expose VALIC to
credit risk in the event of nonperformance by counterparties. VALIC limits this
exposure by entering into agreements with counterparties having high credit
ratings and by regularly monitoring the ratings. VALIC does not expect any
counterparty to fail to meet its obligation; however, nonperformance would not
have a material impact on VALIC's consolidated results of operations and
financial position.

     VALIC's exposure to market risk is mitigated by the offsetting effects of
changes in the value of the agreements and the related items being hedged.

     Carrying amounts and fair values for certain of VALIC's financial
instruments at December 31 are presented below. Care should be exercised in
drawing conclusions based on fair value, since (1) the fair values presented do
not include the value associated with all VALIC's assets and liabilities, and
(2) the reporting of investments at fair value without a corresponding
revaluation of related policyholder liabilities can be misinterpreted.

*    Includes derivative financial instruments with a fair value of $19,342 in

     The following methods and assumptions were used to estimate the fair values
of financial instruments.

     FIXED MATURITY AND EQUITY SECURITIES. Fair values of fixed maturity and
equity securities were based on quoted market prices, where available. For
investments not actively traded, fair values were estimated using values
obtained from independent pricing services or, in the case of some private
placements, by discounting expected future cash flows using a current market
rate applicable to yield, credit quality and average life of the investments.

     MORTGAGE LOANS ON REAL ESTATE. Fair value of mortgage loans was estimated
primarily using discounted cash flows, based on contractual maturities and
risk-adjusted discount rates.

     POLICY LOANS. Fair value of policy loans was estimated using discounted
cash flows and actuarially-determined assumptions, incorporating market rates.

     INSURANCE INVESTMENT CONTRACTS. Fair value of insurance investment
contracts was estimated using cash flows discounted at market interest rates.

                     TRANSACTIONS WITH AFFILIATED COMPANIES

     In the ordinary course of business, VALIC is occasionally involved in
transactions with affiliated companies. Transactions involving the purchase or
disposal of securities are consummated at the market value of the security on
the date of the transaction. Transactions with affiliated companies during each
of the three years in the period ended December 31, 1998 were as follows:

     Operating expenses include $46,556 in 1998, $22,061 in 1997, and $17,533 in
1996, for amounts paid to AGC or its subsidiaries primarily for rent, data
processing services, use of facilities and investment expenses. Interest paid on
borrowings from AGC totaled $152 in 1998, $501 in 1997, and $455 in 1996.

     On November 4, 1982, VALIC invested $11,853 in 13 1U2% Restricted
Subordinated Note due November 4, 2002 issued by AGC. The principal amount of
the note is due November 4, 2002. Principal payments of $592 were received on
November 4, 1998, 1997, and 1996. VALIC recognized $1,212 in interest income
during 1998, $1,292 for 1997, and $1,372 for 1996.

     On December 31, 1984, VALIC entered into a $48,929 note purchase agreement
with AGC. Under the agreement AGC issued an adjustable rate promissory note in
exchange for VALIC's holdings of AGC preferred stock, common stock and warrants.
The principal amount of the note is due in 20 equal installment payments
commencing December 29, 1985 and concluding December 29, 2004. Principal
payments of $2,446 were received on December 29, 1998, 1997, and 1996. VALIC
recognized $1,048, $1,296, and $1,479 of interest income on the note during
1998, 1997, and 1996, respectively.

     On May 15, 1996, VALIC sold SC Financial Corp Mortgage Notes with a book
value of $13,000 to American General Life Insurance Company of NY. Proceeds from
the sale totaled $13,033 with a profit of $33 recognized on the transaction.

     VALIC paid common stock dividends of $181,000, $50.63 per share; $379,000,
$106.01 per share; and $111,000, $31.05 per share, in 1998, 1997, and 1996,
respectively.

     VALIC received capital contributions of $55,200, $67,000, $250,000, and
$75,000 from AGL on June 30, 1998, December 31, 1998, March 31, 1997, and
December 30, 1996, respectively.

9.   TRANSACTIONS WITH AFFILIATED COMPANIES - (CONTINUED)

     VALIC acquired bonds of various issuers from American General Life and
Accident Insurance Company at a cost of $22,154 and $25,892 on January 30, 1997,
and April 8, 1997, respectively.

     On December 5, 1997, VALIC acquired bonds of various issuers from Western
National Life Insurance Company at a cost of $129,715.

                         COMMITMENTS AND CONTINGENCIES

     VALIC is a defendant in various lawsuits arising in the normal course of
business. VALIC believes it has valid defenses in these lawsuits and is
defending the cases vigorously. VALIC also believes that the total amounts that
would ultimately have to be paid arising from these lawsuits would have no
material effect on its consolidated financial position.

     All 50 states have laws requiring solvent life insurance companies to pay
assessments to state guaranty associations to protect the interests of
policyholders of insolvent life insurance companies. State guaranty fund expense
included in operating costs and expenses was $37, $30, and $2,678, for the years
ended December 31, 1998, 1997, and 1996, respectively. The accrued liability for
anticipated assessments was $4,782, $7,402, and $13,661, at December 31, 1998,
1997, and 1996, respectively. The 1998 liability was estimated by VALIC using
the latest information available from the National Organization of Life and
Health Insurance Guaranty Associations. Although the amount accrued represents
VALIC's best estimate of its liability, this estimate may change in the future.
Additionally, changes in state laws could decrease the amount recoverable
against future premium taxes.

                             EMPLOYEE BENEFIT PLANS

11.1 PENSION PLANS

     VALIC participates in several employee benefit plans which together cover
substantially all of its employees. One of these plans is a defined benefit
plan. Pension benefits under this plan are based on the participant's average
monthly compensation and length of credited service. VALIC's funding policy for
this plan is to contribute annually no more than the maximum amount that can be
deducted for federal income tax purposes.

11.1 PENSION PLANS - (CONTINUED)

     The components of pension expense and underlying assumptions for the
defined benefit plan were as follows:

     Equity and fixed maturity securities were 66% and 32%, respectively, of the
plan's assets at the plan's most recent balance sheet dates. The remaining plan
assets consisted primarily of cash equivalents and investment-related
receivables.

11.2 POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

     VALIC, through AGC, has life, medical, supplemental major medical, and
dental plans for certain retired employees and agents. Most plans are
contributory, with retiree contributions adjusted annually to limit employer
contributions to predetermined amounts. VALIC has reserved the right to change
or eliminate these benefits at any time.

11.2 POSTRETIREMENT BENEFITS OTHER THAN PENSIONS - (CONTINUED)

     The life plans are fully insured; the retiree medical and dental plans are
unfunded and self-insured. The accrued liability for postretirement benefits was
$2,388 and $1,784 at year-end 1998 and 1997, respectively. These liabilities
were discounted at the same rates used for the pension plans. Postretirement
benefit expense in 1998, 1997, and 1996 was $275, $295, and $282, respectively.

                        IMPACT OF YEAR 2000 (UNAUDITED)

     INTERNAL SYSTEMS. VALIC has numerous technology systems that are managed on
a decentralized basis. Year 2000 readiness efforts are therefore being
undertaken by its key business units with centralized oversight. Each business
unit has developed and is implementing a plan to minimize the risk of a
significant negative impact on its operations.

     While the specifics of the plans vary, the 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) reprogram or
replace systems that are not Year 2000 ready, (4) test systems to prove that
they will function into the next century as they do currently, and (5) return
the system to operations. As of December 31, 1998, these activities have been
completed for substantially all of VALIC's critical systems, making them Year
2000 ready. Vendor upgrades for a small number of systems are expected in the
first half of 1999; therefore, activities (3) through (5) are ongoing for these
systems. VALIC will continue to test its systems throughout 1999 to maintain
Year 2000 readiness.

     THIRD PARTY RELATIONSHIPS. VALIC has relationships with various third
parties who also must be Year 2000 ready. These third parties provide (or
receive) resources and services to (or from) VALIC and include organizations
with which VALIC exchanges information. Third parties include vendors of
hardware, software, and information services; providers of infrastructure
services such as voice and data communications and utilities for office
facilities; investors; customers; distribution channels; and joint venture
partners. Third parties differ from internal systems in that VALIC exercises
less, or no, control over their Year 2000 readiness. VALIC has developed a plan
to assess and attempt to mitigate the risks associated with the potential
failure of third parties to achieve Year 2000 readiness. The plan includes the
following activities: (1) identify and classify third party dependencies; (2)
research, analyze, and document Year 2000 readiness for critical third parties;
and (3) test critical hardware and software products and electronic interfaces.
A more detailed evaluation will be completed during first quarter 1999 as part
of VALIC's contingency planning efforts. Due to the various stages of third
parties' Year 2000 readiness, VALIC's testing activities will extend throughout
1999.

     CONTINGENCY PLANS. VALIC has commenced contingency planning to reduce the
risk of Year 2000 related business failures. The contingency plans, which
address both internal systems and third party relationships, include the
following activities: (1) evaluate the consequences of failure of business
processes with significant exposure to Year 2000 risk, (2) determine the
probability of a Year 2000-related failure for those processes that have a high
consequence of failure; (3) develop an action plan to complete contingency plans
for those processes that rank high in consequence and probability of failure;
and (4) complete the applicable action plans. VALIC is currently developing
contingency plans and expects to substantially complete all contingency-planning
activities by April 30, 1999.

     RISKS AND UNCERTAINTIES. Based on its plans to make internal systems ready
for Year 2000, to deal with third party relationships, and to develop
contingency actions, VALIC believes that it will experience, at most, isolated
and minor disruptions of business processes following the turn of the century.
Such disruptions are not expected to have a material effect on VALIC's future
results of operations, liquidity, or financial condition. However, due to the
magnitude and complexity of this project, risks and uncertainties exist and
VALIC is not able to predict a most reasonably likely worst case scenario. If
Year 2000 readiness is not achieved due to nonperformance by significant third
party vendors, VALIC's failure to maintain critical systems as Year 2000 ready,
failure of critical third parties to achieve Year 2000 readiness on a timely
basis, or other unforeseen circumstances in completing VALIC's plans, the Year
2000 issues could have a material adverse impact on VALIC's operations following
the turn of the century.

     COSTS. Through December 31, 1998, VALIC has incurred and expensed $27
million (pretax) related to Year 2000 readiness, including $20 million incurred
during 1998. VALIC currently anticipates that it will incur future costs of
approximately $2 million (pretax) to maintain Year 2000 readiness, complete Year
2000 work on noncritical systems and third party relationships, and complete
contingency planning activities. In addition, VALIC accelerated the planned
replacement of certain systems as part of the Year 2000 plans.

                                CHAIRMAN'S LETTER                              1
================================================================================



TO OUR PARTICIPANTS:

We are pleased to present the December 31, 1998, Annual Report to Contract
Owners for Separate Account A of The Variable Annuity Life Insurance Company. A
summary of the change in unit value for each fund and each product series
(Portfolio Director 1, Portfolio Director 2, Portfolio Director Plus,
Independence Plus, Group Unit Purchase and Impact) appears on pages two and
three.

1998 was a volatile year for investors around the world. Problems that began in
Asia in late 1997 circled the globe throughout 1998. Central banks, fearing the
worst lowered interest rates in the fourth quarter of 1998. The result was an
unexpected and dramatic rise in stock and bond prices worldwide.

The year was marked by extreme flight to quality. Investors general preference
was for larger cap growth in stocks over small cap value stocks, and U.S.
Treasury Securities.

The Standard & Poor's 500 Index, dominated by large cap, high-growth technology
and global consumer product companies, had a total return of 28.58%. The top 15
stocks alone accounted for half of the performance. It was a difficult year for
active equity fund managers, as almost 90% of the active managers lagged the S&P
500 Index returns. Also, the S&P 500 Index returns for the year outperformed
over 71% of all U.S.-traded common stocks. The medium to small-cap companies
lagged, with the large companies S&P MidCap 400 Index returning 6.27% and the
S&P SmallCap 600 Index, producing a negative 1.31%.

There was a greater variability in returns between growth and value components
of the equity indices. In the large capitalization arena, S&P 500/BARRA Growth
Index returned an outstanding 42.16%, while the S&P 500/BARRA Value Index
returned 14.67%. In the mid-cap sector, the S&P 400/BARRA Growth Index returned
34.86% compared to the S&P 400/BARRA Value Index return of 4.67%. However, the
small cap equity returns experienced wide variability, with the S&P SmallCap
600/BARRA Growth Index returning 2.29%, and the S&P SmallCap 600/BARRA Value
returning a negative 5.06%.

Globally, the pattern of investment results was very similar to the U.S. equity
returns. The MSCI world Index returned 22%. The top quintile of growth stocks
outperformed the bottom quintile of value stocks by over two times with returns
of 48% and 17%, respectively.

The yield on the 30 year Treasury bond opened the year at 5.92% and declined to
5.10% by the end of 1998, as the Federal Reserve lowered the federal fund rate
three times between September 29 and November 17, leaving the target rate at
4.75%.

For the year, the bond market return, reflected in the Lehman Aggregate Bond
Index, was 8.69% with the long U.S. Treasury Index showing the highest return of
13.52%, followed by the Long Corporate AA/Better Index 10.52%, and the High
Yield Index with 1.60%. Throughout the developed world international bond prices
appreciated as yields declined.

While international markets outside of North America and Europe remain
unsettled, the U.S. economy is experiencing unprecedented prosperity and growth.
Furthermore, with worldwide inflation rates low, and the Federal Reserve weary
of weakness in Asia and emerging markets, it appears that we can expect a
continuation of the current stable rate environment.

If you have any questions about your contract or this report, we would be happy
to hear from you.

                                  Respectfully,


                                  /s/ THOMAS L. WEST, JR.


                                  Thomas L. West, Jr., Chairman 
                                  The Variable Annuity Life Insurance Company

NOTE B -- SUMMARY OF SIGNIFICANT 
          ACCOUNTING POLICIES

         The assets of the Separate Account are part of VALIC. The following is
a summary of significant accounting policies consistently followed by the
Separate Account in the preparation of its financial statements.

         USE OF ESTIMATES. The financial statements have been prepared in
conformity with generally accepted accounting principles. The preparation of
financial statements requires management to make estimates and assumptions that
affect amounts reported in the financial statements and disclosure of contingent
assets and liabilities. Ultimate results could differ from these estimates.

         INVESTMENT VALUATION. Investments in mutual funds (the "Funds") are
valued at the net asset (market) value per share at the close of each business
day as reported by each Fund.

         INVESTMENT TRANSACTIONS. Investment transactions are accounted for on
the trade date. Realized gains and losses on investments are determined on the
basis of identified cost. Capital gain distributions from mutual funds are
recorded on the ex-dividend date and reinvested upon receipt.

         INVESTMENT INCOME. Dividend income from mutual funds is recorded on
the ex-dividend date and reinvested upon receipt.

         ANNUITY RESERVES. Net purchase payments made by variable annuity
contract owners are accumulated based on the performance of the investments of
the Separate Account until the date the contract owners select to commence
annuity payments. Reserves for annuities on which benefits are currently payable
are provided for based upon estimated mortality and other assumptions, including
provisions for the risk of adverse deviation from assumptions, which were
appropriate at the time the contracts were issued. The 1983(a) Individual
Mortality Table, the Annuity 2000 Mortality Table, and the 1994 Group Annuity
Reserve Mortality Table have been used in the computation of annuity reserves
for currently payable contracts. Participants are able to elect assumed
investment rates between 3.0% and 6.0%, as regulated by the applicable state
laws.

         ACCUMULATION UNITS. VALIC offers both standard and enhanced contracts.
These contracts may have different Separate Account charges.

NOTE C -- TRANSACTIONS WITH AFFILIATES

         VALIC serves as investment advisor ("the Advisor"), transfer agent, and
accounting services agent to AGSPC and AGSPC 3. American General Investment
Management, LLP, an affiliate of the Advisor, serves as investment sub-advisor
to certain AGSPC 3 mutual funds.

         The Separate Account is charged for mortality and expense risks
assumed by VALIC and for distribution and administrative services provided by
VALIC. The standard charge, based on the daily net assets of each division, is
assessed daily based on the following annual rates: for Division 10B, 0.85% on
the first $10,000,000, 0.425% on the next $90,000,000, and 0.21% on the excess
over $100,000,000; for Divisions 1,2,4 through 8, 10A, 10C and 10D, 11 through
17, 33 through 44, 48 through 50, and 58 through 60, 1.00%; and for Divisions
18 through 32, and 51 through 54, 1.25%. Certain mutual funds reimburse to
VALIC a portion of the distribution or administrative costs associated with
offering their funds through a VALIC annuity contract. VALIC, in turn reduces
the Separate Account charge to that division by the amount of the
reimbursement. The expense reduction is credited daily based on the following
annual rates: for Divisions 21 through 23, 26 through 30, 32 through 44, 48
through 50, and 58 through 60, 0.25%; for Division 31, 0.24% (effective
December 8, 1997, the expense reduction for Division 31 became 0.20% on the
first $75,000,000, and 0.25% on the excess over $75,000,000); and for Division
18, 0.15% (commencing July 1, 1997). Separate Account charges may be reduced if
contracts are issued to certain types of plans that are expected to result in
lower costs to VALIC. Consequently, each division may offer separate "classes"
of units of beneficial interest reflecting reductions in separate account
charges.

         Pursuant to the reorganization agreement entered into on April 17,
1987, which transferred VALIC Separate Accounts One and Two into Separate
Account A Divisions 10A and 10B, respectively, expenses of each division (as
defined to include underlying mutual fund expenses) are limited to the
following rates based on average daily net assets: Division 10A, 1.4157% on the
first $359,065,787, 1.36% on the next $40,934,213, and 1.32% on the excess over
$400,000,000; Division 10B, 0.6966% on the first $25,434,267, 0.5% on the next
$74,565,733, and 0.25% on the excess over $100,000,000. Accordingly, during the
years ended December 31, 1998 and 1997, VALIC reduced expenses of Division 10B
by $82,027 and $85,996, respectively.

         A portion of the annual contract maintenance charge is assessed on
each contract (except those relating to Divisions 10A and 10B) by VALIC on the
last day of the calendar quarter in which VALIC receives the first purchase
payment, and in quarterly installments thereafter during the accumulation
period. Maintenance charges assessed totaled $5,575,601 and $4,510,903 for the
years ended December 31, 1998 and 1997, respectively.

         VALIC received surrender charges of $4,581,641 and $2,769,370 for the
years ended December 31, 1998 and 1997, respectively. In addition, VALIC
received $53,171 and $6,156 for the year ended December 31, 1998, in sales load
on variable annuity purchase payments for Divisions 10A and 10B, respectively.
VALIC received $63,727 and $7,426 for the year ended December 31, 1997, in
sales load on variable annuity purchase payments for Divisions 10A and 10B,
respectively.

         VALIC contributed to the Separate Account, $100,000 and $74,900,000 on
August 26, 1998 and September 1, 1998, respectively, in order to provide
initial funding for the AGSPC 3 mutual funds. Capital surplus amounts reflected
in the Statements of Net Assets for Divisions 33 through 44, 48 through 50 and
58 through 60 are not subject to contract holder charges since they do not
represent reserves for annuity contracts issued. 

NOTE D -- INVESTMENTS

NOTE G -- YEAR 2000 (UNAUDITED)

         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.

         In addition, the Separate Account 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, as
well as contingency plans for any identified risks or shortcomings, 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 December 31, 1998, VALIC has incurred and expensed $26.7
million (pretax) related to Year 2000 readiness, including $20.2 million
incurred in 1998.

         As of December 31, 1998, VALIC has completed the inventory,
assessment, testing, reprogramming and implementation phases of the plan with
respect to its critical systems. VALIC believes its comprehensive plan and
resource commitment will allow it to meet its Year 2000 objectives. However,
the Year 2000 issue remains complex and the risks, uncertainties, and
unforeseen circumstances associated with the Year 2000 issue could have a
material adverse impact on VALIC and the Separate Account.

================================================================================


TO THE BOARD OF THE VARIABLE ANNUITY LIFE INSURANCE COMPANY AND CONTRACT OWNERS
OF THE VARIABLE ANNUITY LIFE INSURANCE COMPANY SEPARATE ACCOUNT A

We have audited the accompanying statements of net assets of The Variable
Annuity Life Insurance Company Separate Account A ("the Separate Account") and
each of the divisions (1, 2, 4, 5, 6, 7, 8, 10A, 10B, 10C, 10D, 11 through 44
inclusive, 48 through 51 inclusive, and 58 through 60, inclusive) comprising
the Separate Account as of December 31, 1998. We have also audited the related
statements of operations for the year then ended and the statements of changes
in net assets for each of the two years in the period then ended of the
Separate Account and each of its divisions except for divisions 33 through 44
inclusive, divisions 48 through 50 inclusive, and divisions 58 through 60,
inclusive, for which we have audited the statements of operations and changes
in net assets for the period from August 26, 1998 (inception) to December 31,
1998, and for division 51 for which we have audited the statements of
operations and changes in net assets for the period from September 22, 1998
(inception) through December 31, 1998. These financial statements are the
responsibility of the Separate Account's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits 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 statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of December 31, 1998,
by correspondence with the transfer agents. 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 audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Separate Account and each
of the divisions comprising the Separate Account at December 31, 1998, and the
results of their operations and changes in their net assets for each of the
periods identified above, in conformity with generally accepted accounting
principles.

                              GENERAL INFORMATION
    
 
   
     The Variable Annuity Life Insurance Company (the "Company") is a stock life
insurance company organized under the laws of the State of Texas and is engaged
primarily in the offering and issuance of fixed and variable retirement annuity
contracts and combinations thereof. The Company also is licensed to write life
insurance in all states (other than Connecticut) and the District of Columbia,
and annuities in all fifty states and the District of Columbia. The Company is
an indirectly wholly owned subsidiary of American General Corporation.
    
 
   
     On July 25, 1979, the Company established Separate Account A (the Separate
Account) in accordance with the Texas Insurance Code. The Separate Account is
registered with the Securities and Exchange Commission ("SEC") as a unit
investment trust under the Investment Company Act of 1940 (the "Act").
    
 
   
     Each Division of the Separate Account (except for AGSPC's International
Government Bond Fund which is a non-diversified Fund) invests in the shares of a
diversified, open-end, management-type investment company registered under the
Act, or a portfolio of a diversified, open-end, management investment company
registered under the Act. The Separate Account currently is made up of 53
Divisions.
    
 
   
MARKETING INFORMATION
    
 
     The Company has targeted not-for-profit organizations as the central focus
of its marketing efforts for its Contracts. The Company has utilized as its
general marketing theme the concept that the Company is "America's Retirement
Plan Specialists." Specifically, the Company's marketing thrust is aimed at
individuals and groups associated with public and private schools, colleges and
universities, not-for-profit health care organizations, state and local
governments and other not-for-profit organizations.
 
   
     This marketing concept has proven to be successful. In the aggregate,
premium deposits to the Company have grown from $37,000 in 1956 to more than
$3.7 billion as of December 31, 1998. The number of aggregate participant
accounts has increased from 155,000 accounts in 1980 to more than 1,954,190
accounts as of December 31, 1998. The number of employer groups which have
purchased Contracts has increased by 178 percent in the past ten years to more
than 28,094 as of December 31, 1998. As of December 31, 1998, the Company was
ranked in the top 1 percent of all U.S. life insurance companies with regard to
asset size. As of December 31, 1998 the Company's assets totaled more than $39
billion.
    
 
     The Company's growth can also be reviewed by examining each market segment
the Company targets.
 
   
     As of December 31, 1998, the Company was marketing Contracts in more than
10,218 public and private, primary and secondary schools with more than 494,584
participant accounts for employees in public and private schools nationwide.
From December 31, 1988 to December 31, 1998, the cash value of investments in
these Contracts has increased by 269 percent while the number of public and
private school groups in these Contracts increased 97 percent and the number of
participant accounts in these Contracts increased by 111 percent.
    
 
   
     The Company has also increased its marketing efforts to colleges and
universities. From December 31, 1988 to December 31, 1998, the number of
colleges and universities which allow the Company to market Contracts to its
faculty and staff members has increased 166 percent and for the same period the
number of participant accounts has increased 131 percent. For the same time
period cash values for participants have increased 306 percent. As of December
31, 1998, more than 33 percent of United States colleges and universities allow
the Company to market Contracts to their faculty and staff members.
    
 
     The Company has utilized as the central focus in its marketing to college
and university faculty and staff members the theme that the Company is the
"Alternative of Choice."
 
   
     The Company has also had growth in the healthcare segment of the
not-for-profit organization market. From December 31, 1988 to December 31, 1998
Contract cash values have increased 802 percent. During the same period the
number of healthcare groups that have purchased these Contracts increased 274
percent and the number of participant accounts increased 727 percent.
    
 
                                        4
<PAGE>   778
 
     The Company has also experienced growth in contracts sold to state and
local governmental groups. From December 31, 1988 to December 31, 1998, Contract
cash values for participants in these groups have increased 310 percent. For the
same period the number of participant accounts for individuals in these groups
in these Contracts increased 229 percent and the number of employer groups has
increased 303 percent.
 
     Additionally, several states have enacted, as an alternative to state
administered defined benefit retirement programs, Optional Retirement Plans
(ORPs). A state that sponsors an ORP will select the carriers which will be
allowed to participate in the ORP. The Company has been selected as one of the
carriers permitted to market Contracts to state employees who elect to
participate in the ORP in 28 of the last 31 states to sponsor ORPs as an
alternative to a state defined, benefit plan and offers multiple carriers, as of
December 31, 1998. From December 31, 1993 to December 31, 1998, in these ORPs
the number of participant accounts increased 81 percent and cash values
increased 153 percent to nearly $2.7 billion dollars.
 
     The Company may, from time to time, refer to a general investment strategy
known as indexing. Several of the Divisions employ this investment strategy. The
Company may compare the performance of these Divisions to the S&P 500 Index, S&P
MidCap 400 Index, Russell 2000 Index, Morgan Stanley Capital International
Europe, Australia, and Far East (EAFE) Index, or any other appropriate market
index. The indexes are not managed funds and have no identifiable investment
objectives.
 
     The Company may, from time to time, refer, individually or collectively, to
its package of retirement plan services. Collectively, this package of services
may be referred to as easy Retirement Plan, easy Retirement Plan includes: (1)
personal, face-to-face service from highly trained VALIC Retirement Planning
Specialists; (2) informative retirement-investment education programs, seminars
and materials; (3) specialized computer-aided services for retirement planning
and developing asset allocation strategies; (4) a wide selection of innovative,
market-responsive investment options; (5) advanced and efficient administration
of retirement accounts; and (6) a financially strong and stable Company with
which to do business.
 
     The Company may, from time to time refer to the diversifying process of
asset allocation based on the Modern Portfolio Theory developed by Nobel
Prize-winning economist Harry Markowitz. The basic assumptions of Modern
Portfolio Theory are that the selection of individual investments has little
impact on portfolio performance, market timing strategies seldom work, markets
are efficient and selecting the suitable mix of asset classes is more important
when creating a long-term investment portfolio. Modern Portfolio Theory allows
an investor to determine an "efficient" or "optimized" portfolio that has
historically provided a higher return with the same risk or the same return with
lower risk.
 
     When presenting the asset allocation process the Company may outline the
process of personal and investment risk analysis including determining
individual risk tolerances and a discussion of the different types of investment
risk. The Company may classify investors into five categories based on their
personal risk tolerance and will quote various industry experts on which types
of investments are best suited to each of the five risk categories. The industry
experts quoted may include Ibbotson Associates, CDA Investment Technologies,
Lipper Analytical Services, Laffer-Cantos, Inc., The Variable Annuity Research &
Data Services ("VARDS") Report, Wilson Associates, Morningstar, Inc. and any
other expert which has been deemed by the Company to be appropriate. The Company
may also provide a historical overview of the performance of a variety of
investment market indexes and different asset categories, such as stocks, bonds,
cash equivalents, etc. The Company may also discuss investment volatility
(standard deviation) including the range of returns for different asset
categories and classes over different time horizons, and the correlation between
the returns of different asset categories and classes. The Company may also
discuss the basis of portfolio optimization including the required inputs and
the construction of efficient portfolios using sophisticated computer-based
techniques. Finally, the Company may describe various investment strategies and
methods of implementation such as the use of index funds vs. actively managed
funds, the use of dollar cost averaging techniques, the tax status of
contributions, and the periodic rebalancing of diversified portfolios.
 
     The Company, in its marketing efforts to each of the market segments, may
from time to time design sales literature and material specifically for
 
                                        5
<PAGE>   779
 
that market segment, e.g., the health care segment of the not-for-profit
organization market. This sales literature and material may also be specific to
a certain group. For example, sales literature and material may be designed for
a specific hospital. The sales literature and material would address
specifically the group's contract and retirement plan.
 
     The Company, in its marketing efforts, may also refer to the following
investment advisers referenced in the Prospectus.
 
     The Company may, from time to time, refer to The Dreyfus Corporation as
adviser for the Dreyfus Small Cap Portfolio (underlying Division Eighteen).
Dreyfus has been helping Americans invest for their future with quality mutual
funds for more than four decades. In 1994, Dreyfus joined forces with Mellon
Bank and the Boston Company to form an investment management organization with
over $300 billion in assets under management. Through 10 investment subsidiaries
and affiliates, Dreyfus/Mellon Global Asset Management offers a broad array of
products and services and a spectrum of investment opportunities designed to
provide competitive returns at varying risk levels. Dreyfus, as of December 31,
1998, had approximately $110 billion of assets under management.
 
     For more than 40 years, the Templeton organization has been a leading
investment management company with offices in the U.S., Australia, Bahamas,
Canada, Hong Kong, Luxembourg, Singapore, Russia, Scotland and Germany.
Templeton is a member of the over $220 billion Franklin Templeton Group with
approximately 7 million individual and institutional accounts. The Franklin
Templeton Group provides investment management and advisory services to a
world-wide client base and maintains a disciplined, long-term approach to value-
oriented global and internal investing. Templeton, as of December 31, 1998, had
approximately $90 billion in assets under management.
 
     The Company may, from time to time, refer to T. Rowe Price Associates, Inc.
(T. Rowe Price), as subadviser to the AGSPC Science & Technology Fund
(underlying Division Seventeen) and the AGSPC Growth Fund (underlying Division
Fifteen). T. Rowe Price, one of the nation's leading no-load mutual fund
managers, manages money for more than 6 million individual and institutional
accounts on the basis of proprietary research and a strict investment discipline
developed over 60 years. T. Rowe Price has delivered strong performance for its
clients by investing in both large- and small-growth companies which operate in
the service sector of the economy, and also by investing in common stocks of
companies expected to benefit from the development, advancement and use of
science and technology. This includes industries such as telecommunications,
computers, software, medical devices and biotechnology. T. Rowe Price, together
with its affiliates, as of December 31, 1998, had more than $148 billion of
assets under management.
 
     The Company may, from time to time, refer to the Bankers Trust Company as
subadviser to AGSPC Stock Index Fund (underlying Division 10), AGSPC MidCap
Index Fund (underlying Division 4), and AGSPC Small Cap Index Fund (underlying
Division 14).
 
     Bankers Trust Company is a wholly owned subsidiary of Bankers Trust
Corporation. On November 30, 1998, Bankers Trust Corporation entered into an
Agreement and Plan of Merger with Deutsche Bank AG under which Bankers Trust
Corporation and all of its subsidiaries would merge with and into a subsidiary
of Deutsche Bank AG. Deutsche Bank AG is a major global banking institution that
is engaged in a wide range of financial services, including retail and
commercial banking, investment banking and insurance. The merger is contingent
upon various regulatory approvals. On April 20, 1999, the AGSPC Fund's Board of
Directors approved a new investment sub-advisory agreement with Bankers Trust
Company, subject to shareholder approval. If the merger is approved and
completed, Deutsche Bank AG, as the Sub-Adviser's new parent company, will
control the operations of the Sub-Adviser. Bankers Trust believes that, under
this new arrangement, the services provided to the Fund will be maintained at
their current level.
 
     On March 11, 1999, Bankers Trust announced that it had reached an agreement
with the United States Attorney's Office in the Southern District of New York to
resolve an investigation concerning inappropriate transfers of unclaimed funds
and related recordkeeping problems that occurred between 1994 and early 1996.
Pursuant to its agreement with the U.S. Attorney's Office, Bankers Trust pleaded
guilty to misstating entries in the bank's books and records and agreed to pay a
                                        6
<PAGE>   780
 
$60 million fine to federal authorities. Separately, Bankers Trust agreed to pay
a $3.5 million fine to the State of New York. The events leading up to the
guilty pleas did not arise out of the investment advisory or mutual fund
management activities of Bankers Trust or its affiliates.
 
     As a result of the plea, absent an order from the SEC, Bankers Trust would
not be able to continue to provide investment advisory services to the Fund. The
SEC has granted a temporary order to permit Bankers Trust and its affiliates to
continue to provide investment advisory services to registered investment
companies. There is no assurance that the SEC will grant a permanent order.
 
     The Company may, from time to time, refer in advertisements or sales
materials to certain milestones which are intended to emphasize the Company's
growth and development in assets, groups and various market segments. The
Company may also refer to other versions of Portfolio Director in advertisements
or sales material. The Company may refer to certain aspects of its products such
as having a variety of shared mutual funds available as Variable Account
Options. Additionally the Company may refer from time to time in advertisements
or sales materials to marketing strategies it utilizes to promote the Company's
business objectives. Further, the Company may refer from time to time in
advertisements or sales materials to certain value-added services it provides to
its groups, Contract Owners and Participants.
 
     The Company may, from time to time, refer in its advertisements to Schwab
Personal Choice Retirement Accounts ("PCRA"). The PCRA is a self-directed
brokerage account that may be used by VALIC Participants to directly invest in
publicly available mutual funds. PCRA is marketed through the VALIC Investment
Services Company.
 
     The Company may from time to time compare the performance of the mutual
funds that serve as the investment vehicles for Portfolio Director to the
performance of certain market indices. These market indices are described in the
"Performance Information" Section of this Statement of Additional Information.
 
ENDORSEMENTS AND
PUBLISHED RATINGS
 
     From time to time, in advertisements or in reports to Contract Owners, the
Company may refer to its endorsements. Endorsements are often in the form of a
list of organizations, individuals or other parties which recommend the Company
or the Contracts. The endorser's name will be used only with the endorser's
consent. It should be noted that the list of endorsements may change from time
to time.
 
     Also from time to time, the rating of the Company as an insurance company
by A. M. Best may be referred to in advertisements or in reports to Contract
Owners. Each year the A. M. Best Company reviews the financial status of
thousands of insurers, culminating in the assignment of Best's Ratings. These
ratings reflect their current opinion of the relative financial strength and
operating performance of an insurance company in comparison to the norms of the
life/health insurance industry. Best's Ratings range from A++ to F. An A++
rating means, in the opinion of A. M. Best, that the insurer has demonstrated
the strongest ability to meet its respective policyholder and other contractual
obligations.
 
     In addition, the claims-paying ability of the Company as measured by the
Standard and Poor's Ratings Group may be referred to in advertisements or in
reports to Contract Owners. A Standard and Poor's insurance claims-paying
ability rating is an assessment of an operating insurance company's financial
capacity to meet the obligations of its insurance policies in accordance with
their terms. Standard and Poor's ratings range from AAA to D.
 
     Further, from time to time the Company may refer to Moody's Investor's
Service's rating of the Company. Moody's Investor's Service's financial strength
ratings indicate an insurance company's ability to discharge senior policyholder
obligations and claims and are based on an analysis of the insurance company and
its relationship to its parent, subsidiaries and affiliates. Moody's Investor's
Service's ratings range from Aaa to C.
 
     The Company may additionally refer to its Duff & Phelp's rating. A Duff &
Phelp's rating is an assessment of a company's insurance claims paying ability.
Duff & Phelp's ratings range from AAA to CCC. An AAA rating reflects that a
company has the highest claims paying ability.
 
     Ratings relate to the claims paying ability of the Company's General
Account and not the investment characteristics of the Separate Account.
 
     The Company may from time to time, refer to Lipper Analytical Services
Incorporated ("Lip-
 
                                        7
<PAGE>   781
 
per"), Morningstar, Inc. ("Morningstar") and CDA/Wiesenberger Investment
Companies (CDA/Wiesenberger) when discussing the performance of its Divisions.
Lipper, Morningstar and CDA/Wiesenberger are leading publishers of statistical
data about the investment company industry in the United States.
 
     Additionally, the Company may compare the performance of the Divisions to
categories published by Lipper and Morningstar. The published categories which
may be utilized in comparison with the performance of the Divisions include the
Morningstar Growth and Income Mutual Fund Category, Morningstar Aggressive
Growth Mutual Fund Category, Morningstar Growth Mutual Fund Category,
Morningstar International Stock Mutual Fund Category, Lipper Growth and Income
Mutual Fund Category, Lipper Small Company Growth Mutual Fund Category, Lipper
Growth Mutual Fund Category and Lipper International Mutual Fund Category.
Additional Lipper or Morningstar categories may be utilized if they are deemed
by the Company relevant to the performance of the Company's Divisions.
 
     The Company may, from time to time, refer to the VARDS. The VARDS Report
offers monthly analysis of the variable annuity industry, including marketing
and performance information.
 
     The Company may, from time to time, refer to Bankers Trust Company's
Tactical Asset Allocation Model's historical performance and compare such
performance to that of the S&P 500 Index. Neither the Model nor the S&P 500
Index is a managed fund and neither have identifiable investment objectives.
 
     Finally the Company will utilize as a comparative measure for the
performance of its Funds the Consumer Price Index ("CPI"). The CPI is a measure
of change in consumer prices, as determined in a monthly survey of the U.S.
Bureau of Labor Statistics. Housing costs, transportation, food, electricity,
changes in taxes and labor costs are among the CPI components. The CPI provides
a tool for determining the impact of inflation on an individual's purchasing
power.
 
TYPES OF VARIABLE ANNUITY
CONTRACTS
 
     Flexible payment deferred annuity Contracts are offered in connection with
the prospectus to which this Statement of Additional Information relates.
 
     Under flexible payment Contracts, Purchase Payments generally are made
until retirement age is reached. However, no Purchase Payments are required to
be made after the first payment. Purchase Payments are subject to any minimum
payment requirements under the Contract.
 
     Under deferred annuity contracts, Purchase Payments are invested and
accumulate on a fixed or variable basis until the date the Contract Owner
selects to commence annuity payments.
 
     Under immediate annuity Contracts, the first annuity payment is made on the
first day of the second month after the Purchase Payment is received. During the
period before the Annuity Date, the Purchase Payments are invested in the same
manner, and the other terms and conditions (including the options and rights of
Contract Owners, Annuitants and Beneficiaries) are the same under immediate
annuity Contracts as under deferred annuity Contracts.
 
     The Contracts are non-participating and will not share in any of the
profits of the Company.
 
FEDERAL TAX MATTERS
 
     This Section summarizes the major tax consequences of contributions,
payments, and withdrawals under Portfolio Director, during life and at death.
 
TAX CONSEQUENCES OF PURCHASE PAYMENTS
 
     403(b) Annuities. Purchase Payments made by Section 501(c)(3) tax-exempt
organizations and public educational institutions toward Contracts for their
employees are excludable from the gross income of employees, to the extent
aggregate Purchase Payments do not exceed several competing tax limitations.
This gross income exclusion applies both to employer contributions and to your
voluntary and nonelective salary reduction contributions.
 
     Your voluntary salary reduction contributions are generally limited to the
lesser $10,000 ($9,500
 
                                        8
<PAGE>   782
 
before 1998), although additional, "catch-up" contributions are permitted under
certain circumstances. Combined employer and salary reduction contributions are
generally limited to the smallest of: $30,000; approximately 25% of salary; or
an exclusion allowance which takes into account a number of factors. In
addition, after 1988 employer contributions for highly compensated employees may
be further limited by applicable nondiscrimination rules.
 
     401(a) and 403(a) Qualified Plans. Purchase Payments made by an employer
(or a self-employed individual) under a qualified pension, profit-sharing or
annuity plan are excluded from the gross income of the employee. Purchase
Payments made by an employee generally are made on an after-tax basis, unless
eligible for pre-tax treatment by reason of Sections 401(k) or 414(h).
 
     408(b) Individual Retirement Annuities ("408(b) IRAs"). Annual
tax-deductible contributions for 408(b) IRA Contracts are limited to the lesser
of $2,000 or 100% of compensation, and generally fully deductible only by
individuals who:
 
 (i) are not active participants in another retirement plan, and are not
     married;
 
 (ii) are not active participants in another retirement plan, are married, but
      either (a) the spouse is not an active participant in another retirement
      plan; or (b) the spouse is an active participant, but the couple's
      adjusted gross income does not exceed $150,000.
 
(iii) are active participants in another retirement plan, are unmarried, and
      have adjusted gross income of $31,000 or less ($30,000 or less prior to
      1998; adjusted upward for inflation after 1998); or
 
(iv) are active participants in another retirement plan, are married, and have
     adjusted gross income of $51,000 or less ($50,000 for 1998, $40,000 or less
     prior to 1998; adjusted upward for inflation after 1998).
 
     Active participants in other retirement plans whose adjusted gross income
exceeds the limits in (ii), (iii) or (iv) by less than $10,000 are entitled to
make deductible 408(b) IRA contributions in proportionately reduced amounts. If
a 408(b) IRA is established for a nonworking spouse who has no compensation, the
annual tax-deductible Purchase Payments for both spouses' Contracts cannot
exceed the lesser of $4,000 or 100% of the working spouse's earned income, and
no more than $2,000 may be contributed to either spouse's IRA for any year.
 
     You may be eligible to make nondeductible IRA contributions of an amount
equal to the excess of:
 
 (i) the lesser of $2,000 ($4,000 for you and your spouse's IRA) or 100% of
     compensation, over
 
(ii) your applicable IRA deduction limit.
 
     You may also make contributions of eligible rollover amounts from other
qualified plans and contracts. See Tax-Free Rollovers, Transfers and Exchanges.
 
     408A "Roth" Individual Retirement Annuities ("408A "Roth" IRAs"). After
1997, annual nondeductible contributions for 408A "Roth" IRA Contracts are
limited to the lesser of $2,000 or 100% of compensation, and may be made only by
individuals who:
 
(i) are unmarried and have adjusted gross income of $95,000 or less; or
 
(ii) are married and filing jointly, and have adjusted gross income of $150,000
     or less.
 
The available nondeductible 408A "Roth" IRA contribution is reduced
proportionately to zero where adjusted gross income exceeds the limit in (i) by
$15,000 or less, or the limit in (ii) by $10,000 or less. Similarly, individuals
who are married and filing separately and whose adjusted gross income is less
than $15,000 may make a contribution to a Roth IRA of a portion of the otherwise
applicable $2,000 or 100% of compensation limit.
 
     All contributions to 408(b) IRAs, traditional nondeductible IRAs and 408A
"Roth" IRAs must be aggregated for purposes of the $2,000 annual contribution
limit.
 
     457 Plans. A unit of a state or local government may establish a deferred
compensation program for individuals who: (i) perform services for the
government unit, and (ii) belong to a select group of management or highly
compensated employees and/or independent contractors.
 
     This type of program allows eligible individuals to defer the receipt of
compensation (and taxes thereon) otherwise presently payable to them. If the
program is an eligible deferred compensation plan (an "EDCP"), in 1999 you may
contribute (and defer tax on) the lesser of $8,000 (indexed for
 
                                        9
<PAGE>   783
 
inflation) or 33 1/3% of your "includible" compensation (compensation from the
employer currently includible in taxable income). Additional, catch-up deferrals
are permitted in the final three years before the year you reach normal
retirement age.
 
     The employer uses deferred amounts to purchase the Contracts offered by
this prospectus. For plans maintained by a unit of a state or local government,
the Contract is generally held for the exclusive benefit of plan participants,
although certain Contracts may remain subject to the claims of the employer's
general creditors until 1999. The employee has no present rights to any vested
interest in the Contract and is entitled to payment only in accordance with the
EDCP provisions.
 
     Simplified Employee Pension Plan ("SEP") Employer contributions under a SEP
are made to a separate individual retirement account or annuity established for
each participating employee, and generally must be made at a rate representing a
uniform percent of participating employees' compensation. Employer contributions
are excludable from employees' taxable income, and after 1993 cannot exceed the
lesser of $30,000 or 15% of your compensation.
 
     Through 1996, employees of certain small employers (other than tax-exempt
organizations) were permitted to establish plans allowing employees to
contribute pretax, on a salary reduction basis, to the SEP. In 1998 and 1999,
these salary reductions may not exceed $100,000 per year. This limit is indexed
and may be included in future years. These salary reduction contributions may
not exceed $7,000, indexed for inflation in later years. Such plans if
established by December 31, 1996, may still allow employees to make these
contributions.
 
     SIMPLE IRA. Employer and employees contributions under a SIMPLE Retirement
Account Plan are made to a separate individual retirement account or annuity for
each employee. Employee salary reduction contributions cannot exceed $6,000 in
any year. Employer contributions can be a matching or a nonelective contribution
of a percentage as specified in the Code. Only employers with 100 or fewer
employees can maintain a SIMPLE IRA plan, which must also be the only plan the
employer maintains.
 
     Unfunded Deferred Compensation Plans. Private taxable employers may
establish unfunded, non-qualified deferred compensation plans for a select group
of management or highly compensated employees and/or for independent
contractors. Certain arrangements of nonprofit employers entered into prior to
August 16, 1986, and not subsequently modified, are also subject to the rules
discussed below.
 
     An unfunded, deferred compensation plan is a bare contractual promise on
the part of the employer to defer current wages to some future time. The
Contract is owned by the employer and remains subject to the claims of the
employer's general creditors. Private taxable employers that are not natural
persons, however, are currently taxable on any increase in the Purchase Unit
Value attributable to Purchase Payments made after February 28, 1986 to such
Contracts. Participants have no present right or vested interest in the Contract
and are only entitled to payment in accordance with plan provisions.
 
     Non-Qualified Contracts. Purchase Payments made under Non-Qualified
Contracts are neither excludible from the gross income of the Contract Owner nor
deductible for tax purposes. However, any increase in the Purchase Unit Value of
a Non-Qualified Contract resulting from the investment performance of VALIC
Separate Account A is not taxable to the Contract Owner until received by him.
Contract Owners that are not natural persons, however, are currently taxable on
any increase in the Purchase Unit Value attributable to Purchase Payments made
after February 28, 1986 to such Contracts.
 
TAX CONSEQUENCES OF DISTRIBUTIONS
 
     403(b) Annuities. Voluntary salary reduction amounts accumulated after
December 31, 1988, and earnings on voluntary contributions before and after that
date, may not be distributed before one of the following:
 
(1) attainment of age 59 1/2;
 
(2) separation from service;
 
(3) death;
 
(4) disability, or
 
(5) hardship (hardship distributions are limited to salary reduction
    contributions only, exclusive of earnings thereon).
 
                                       10
<PAGE>   784
 
     Similar restrictions will apply to all amounts transferred from a section
403(b)(7) custodial account other than rollover contributions.
 
     Distributions are taxed as ordinary income to the recipient in accordance
with Section 72.
 
     401(a) and 403(a) Qualified Plans. Distributions from Contracts purchased
under qualified plans are taxable as ordinary income, except to the extent
allocable to an employee's after-tax contributions (investment in the Contract).
If you or your Beneficiary receive a "lump sum distribution" (legally defined
term), the taxable portion may be subject to special 5-year or 10-year income
averaging treatment. Five-year forward averaging is unavailable for
distributions occurring after December 31, 1999. Ten-year income averaging uses
tax rates in effect for 1986, allows 20% capital gains treatment for the taxable
portion of a lump sum distribution attributable to years of service before 1974,
and is available if you were 50 or older on January 1, 1986.
 
     408(b) IRAs, SEPs and SIMPLE IRAs. Distributions are generally taxed as
ordinary income to the recipient. Rollovers from an IRA to a Roth IRA, and
conversions of an IRA to a Roth IRA, where permitted, are generally taxable in
the year of the rollover or conversion. Such rollovers of conversions completed
in 1998 are generally eligible for pro-rata federal income taxation over four
years. Individuals with adjusted gross income over $100,000 are generally
ineligible for such conversions, regardless of marital status, as are married
individuals who file separately.
 
     408A "Roth" IRAs. "Qualified" distributions upon attainment of age 59 1/2,
upon death, disability or for first-time homebuyer expenses are tax-free as long
as five or more years have passed since the first contribution to taxpayer's
first 408A "Roth" IRA. A later date may apply to distributions from a Roth IRA
which contains one or more rollover contributions from a traditional IRA, to
determine if the distribution is qualified distribution. Qualified distributions
may be subject to state income tax in some states. Other distributions are
generally taxable to the extent that the distribution exceeds purchase payments.
 
     457 Plans. Amounts received from an EDCP are includible in gross income for
the taxable year in which are paid or otherwise made available to the recipient.
 
     Unfunded Deferred Compensation Plans. Amounts received are includible in
gross income for the taxable year in which are paid or otherwise made available
to the recipient.
 
     Non-Qualified Contracts. Partial redemptions from a Non-Qualified Contract
purchased after August 13, 1982 (or allocated to post-August 13, 1982 Purchase
Payments under a pre-existing Contract), generally are taxed as ordinary income
to the extent of the accumulated income or gain under the Contract if they are
not received as an annuity. Partial redemptions from a Non-Qualified Contract
purchased before August 14, 1982 are taxed only after the Contract Owner has
received all of his pre-August 14, 1982 investment in the Contract. The amount
received in a complete redemption of a Non-Qualified Contract (regardless of the
date of purchase) will be taxed as ordinary income to the extent that it exceeds
the Contract Owners's investment in the Contract. Two or more Contracts
purchased from VALIC (or an affiliated company) by a Contract Owner within the
same calendar year, after October 21, 1988, are treated as a single Contract for
purposes of measuring the income on a partial redemption or complete surrender.
 
     When payments are received as an annuity, the Contract Owner's investment
in the Contract is treated as received ratably and excluded ratably from gross
income as a tax-free return of capital, over the expected payment period of the
annuity. Individuals who begin receiving annuity payments on or after January 1,
1987 can exclude from income only their unrecovered investment in the Contract.
Upon death prior to recovering tax-free their entire investment in the Contract,
such individuals generally are entitled to deduct the unrecovered amount on
their final tax return.
 
SPECIAL TAX CONSEQUENCES -- EARLY
DISTRIBUTION
 
     403(b) Annuities, 401(a) and 403(a) Qualified Plans, 408(b) IRAs, SEPs and
SIMPLE IRAs. Taxable distributions received before the recipient attains age
59 1/2 generally are subject to a 10% penalty tax in addition to regular income
tax. Distributions on account of the following generally are excepted from this
penalty tax:
 
(1) death;
 
(2) disability;
 
                                       11
<PAGE>   785
 
(3) separation from service after a participant reaches age 55 (only applies to
    403(b), 401(a) 403(a));
 
(4) separation from service at any age if the distribution is in the form of
    substantially equal periodic payments over the life (or life expectancy) of
    the Participant (or the Participant and Beneficiary), and
 
(5) distributions which do not exceed the employee's tax deductible medical
    expenses for the taxable year of receipt.
 
Separation from service is not required for distributions from an IRA, SEP or
SIMPLE IRA under #4 above. Certain distributions from a SIMPLE IRA within two
years after first participating in the plan may be subject to a 20% penalty,
rather than a 10% penalty.
 
Currently, distributions from 408(b) IRAs on account of the following additional
reasons are also excepted from this penalty tax:
 
(6) distributions up to $10,000 (in the aggregate) to cover costs of acquiring,
    constructing or reconstructing the residence of a first-time homebuyer, and
 
(7) distributions to cover certain costs of higher education: tuition, fees,
    books, supplies and equipment for the IRA owner, a spouse, child or
    grandchild, and
 
(8) distributions to cover certain medical care or long term care insurance
    premiums, for individuals who have received federal or state unemployment
    compensation for 12 consecutive months.
 
     408A "Roth" IRAs. Distributions, other than "qualified" distributions where
the five-year holding rule is met, are generally subject to the same 10% penalty
tax as other IRAs. Distributions of rollover or conversion contributions from an
IRA which are not qualified distributions, may be subject to additional penalty
taxes.
 
     457 Plans. Distributions generally may be made under an EDCP prior to
separation from service only for unforeseeable emergencies, or for amounts under
$5,000 for inactive Participants, and are includible in the recipient's gross
income in the year paid.
 
     Non-Qualified Contracts. A 10% penalty tax applies to the taxable portion
of a distribution received before age 59 1/2 under a Non-Qualified Contract,
unless the distribution is:
 
(1) to a Beneficiary on or after the Contract Owner's death;
 
(2) upon the Contract Owner's disability;
 
(3) part of a series of substantially equal annuity payments for the life or
    life expectancy of the Contract Owner, or the lives or joint life expectancy
    of the Contract Owner and Beneficiary;
 
(4) made under an immediate annuity contract, or
 
(5) allocable to Purchase Payments made before August 14, 1982.
 
SPECIAL TAX CONSEQUENCES -- REQUIRED
DISTRIBUTIONS
 
     403(b) Annuities. Generally, minimum required distributions must commence
no later than April 1 of the calendar year following the later of the calendar
year in which the Participant attains age 70 1/2 or the calendar year in which
the Participant retires. Required distributions must be made over a period that
does not exceed the life or life expectancies of the Participant (or lives or
joint life expectancies of the Participant and Beneficiary). The minimum amount
payable can be determined several different ways. A penalty tax of 50% is
imposed on the amount by which the minimum required distribution in any year
exceeds the amount actually distributed in that year.
 
     Amounts accumulated under a Contract on December 31, 1986 may be paid in a
manner that meets the above rule or, alternatively:
 
(i)  must begin to be paid when Participant attains age 75; and
 
(ii) the present value of payments expected to be made over the life of the
     Participant, (under the option chosen) must exceed 50% of the present value
     of all payments expected to be made (the "50% rule").
 
The 50% rule will not apply if a Participant's spouse is the joint annuitant.
Notwithstanding these pre-January 1, 1987 rules the entire contract balance must
meet the minimum distribution incidental benefit requirement of Section
403(b)(10).
 
     At the Participant's death before payout has begun, Contract amounts
generally either must be paid to the Beneficiary within 5 years, or must begin
within 1 year of death and be paid over the life or
 
                                       12
<PAGE>   786
 
life expectancy of the Beneficiary. If death occurs after commencement of (but
before full) payout, distributions generally must continue at least as rapidly
as under the method elected by the Participant and in effect at the time of
death.
 
     A participant generally may aggregate his or her 403(b) contracts and
accounts for purposes of satisfying these requirements, and withdraw the
required distribution in any combination from such contracts or accounts, unless
the plan, contract, or account otherwise provides.
 
     401(a) and 403(a) Qualified Plans. Minimum distribution requirements for
Qualified Plans, are generally the same as described for 403(b) Annuities,
except that there is no exception for pre-1987 amounts, and multiple plans may
not be aggregated to satisfy the requirement.
 
     408(b) IRAs, SEPs and SIMPLE IRAs. Minimum distribution requirements are
generally the same as described above for 403(b) Annuities, except that:
 
(1) there is no exception for pre-1987 amounts; and
 
(2) there is no available postponement, past April 1 of the calendar year
    following the calendar year in which age 70 1/2 is attained.
 
     A participant generally may aggregate his or her IRAs inherited from the
same decedent for purposes of satisfying these requirements, and withdraw the
required distribution in any combination from such contracts or accounts, unless
the contract or account otherwise provides.
 
     408A "Roth" IRAs. Minimum distribution requirements generally applicable to
403(b) Annuities, 401(a) and 403(a) Qualified Plans, 408(b) IRAs, SEPs and 457
Plans do not apply to 408A "Roth" IRAs during the owner's lifetime, but
generally do apply at the owner's death.
 
     A participant generally may aggregate his or her Roth IRAs for purposes of
satisfying these requirements, and withdraw the required distribution in any
combination from such contracts or accounts, unless the contract or account
otherwise provides.
 
     457 Plans. Beginning January 1, 1989, the minimum distribution requirements
for EDCP's are generally the same as described above for 403(b) Annuities except
that there is no exception for pre-1987 amounts, and multiple plans may not be
aggregated to satisfy the requirement.
 
     Non-Qualified Contracts. Non-Qualified Contracts do not require
commencement of distributions at any particular time during the Owner's
lifetime, provided that the Owner is a natural person, and generally do not
limit the duration of annuity payments.
 
     At the Participant's death before payout has begun, Contract amounts
generally either must be paid to the Beneficiary within 5 years, or must begin
within 1 year of death and be paid over the life or life expectancy of the
Beneficiary. If death occurs after commencement of (but before full) payout,
distributions generally must continue at least as rapidly as under the method
elected by the Participant at the time of death.
 
TAX-FREE ROLLOVERS, TRANSFERS AND
EXCHANGES
 
     403(b) Annuities. Tax free transfers between 403(b) annuity contracts
and/or 403(b)(7) custodial accounts, and tax-free rollovers from 403(b) programs
to 408(b) IRAs or other 403(b) programs, are permitted under certain
circumstances.
 
     401(a) and 403(a) Qualified Plans. The taxable portion of certain
distributions may be transferred in a tax-free rollover to an 408(b) individual
retirement account or annuity, or to another such plan.
 
     408(b) IRAs. Funds may be transferred tax-free to an 408(b) IRA Contract in
a tax-free rollover, from a 403(b) Annuity, or 401(a) or 403(a) Qualified Plan,
under certain conditions. These amounts may subsequently be rolled over on a
tax-free basis to another such plan or 403(b) Annuity Contract from this
"conduit" IRA. In addition, tax-free rollovers may be made from one 408(b) IRA
(other than a Roth IRA) to another provided that no more than one such rollover
is made during any twelve-month period.
 
     408A "Roth" IRAs. Funds may be transferred over tax-free from one 408A
"Roth" IRA to another. Funds in a 408(b) IRA may be rolled in a taxable
transaction to a 408A "Roth" IRA by individuals who:
 
 (i) have adjusted gross income of $100,000 or less, whether single or married
     filing jointly;
 
(ii) are not married filing separately.
                                       13
<PAGE>   787
 
     Special, complicated rules governing holding periods, avoidance of the 10%
penalty tax and ratable recognition of 1998 income also apply to rollovers from
408(b) IRAs to 408A "Roth" IRAs, and may be subject to further modification by
Congress. You should consult your tax advisor regarding the application of these
rules.
 
     SEPs. Funds may be rolled over tax free from one SEP only to another SEP or
408(b) IRA.
 
     457 Plans. Tax-free transfer of EDCP amounts are permitted only to another
EDCP.
 
     Unfunded Deferred Compensation Plans. Tax-free transfers or rollovers are
not allowed from these plans.
 
     Non-Qualified Contracts. Certain of the Non-Qualified single payment
deferred annuity Contracts permit the Contract Owner to exchange the Contract
for a new deferred annuity contract prior to the commencement of annuity
payments. The exchange of one annuity contract for another is a tax-free
transaction under Section 1035, but is reportable to the IRS.
 
EXCHANGE PRIVILEGE
 
     In the prospectus we described generally how under certain conditions we
will allow you to exchange from other fixed and/or variable contracts we issue
(other contracts) to Portfolio Director. These other contracts are listed in the
prospectus. A more detailed comparison of the features, charges and restrictions
between each of these listed other contracts and Portfolio Director is provided
below.
 
EXCHANGES FROM INDEPENDENCE PLUS
CONTRACTS
 
     Sales/Surrender Charges. Under an Independence Plus Contract, no sales
charge is deducted at the time a Purchase Payment is made, but a surrender
charge may be imposed on partial or total surrenders. The surrender charge may
not exceed 5% of any Purchase Payments withdrawn within five years of the date
such Purchase Payments were made. The most recent Purchase Payments are deemed
to be withdrawn first. Up to 10% of the Account Value may be surrendered in a
Participant Year without any surrender charge being imposed. Portfolio Director
imposes a similar surrender charge upon total or partial surrenders. Both the
Portfolio Director and Independence Plus Contracts have other similar provisions
where surrender charges are not imposed. However, Portfolio Director provides at
least one additional provision, not included in Independence Plus Contracts,
under which no surrender charge will be imposed. An additional provision allows
election of a systematic withdrawal method without surrender charges. (See
"Surrender Charge" in the prospectus.) For purposes of satisfying the
fifteen-year and five-year holding requirements described under "Surrender
Charge" in the prospectus, Portfolio Director will be deemed to have been issued
on the same date as the Independence Plus Contract or certificate thereunder,
but no earlier than January 1, 1982. Purchase Payments exchanged into Portfolio
Director and which were made within five years before the date of exchange will
be treated as Purchase Payments under Portfolio Director for purposes of
calculating the surrender charge. Exchanged payments will be deemed to have been
made under Portfolio Director on the date they were made to Independence Plus
Contracts for purposes of calculating the surrender charge under Portfolio
Director.
 
     Other Charges. Under the Independence Plus Contracts, a maintenance charge
of $20 is assessed for the first year and an annual charge of $15 is assessed
for the second and later years during the accumulation period. The charge is due
in quarterly installments. A daily fee is charged at the annual rate of 1% of
the daily net asset value allocable to the Variable Subaccounts to cover
administrative expenses (other than those covered by the annual charge) and
mortality risks assumed by the Company. For Portfolio Director, a quarterly
account maintenance fee of $3.75 is assessed for each calendar quarter during
the Purchase Period during which any Variable Account Option Account Value is
credited to a Participant's Account. The fee is to reimburse the Company for
some of the administrative expenses associated with the Variable Account
Options. No fee is assessed for any calendar quarter if the Account Value is
credited only to the Fixed Account Options throughout the quarter. Such fee
begins immediately if an exchange is made into any Variable Account Option
offered under Portfolio Director. The fee may also be reduced or waived by the
Company for Portfolio Director if the administrative expenses are expected to be
lower for that Contract. (See "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" in the prospectus.) To cover expenses
 
                                       14
<PAGE>   788
 
not covered by the account maintenance fee and to compensate the Company for
assuming mortality risks and administration and distribution expenses under
Portfolio Director, an additional daily charge with an annualized rate of 1.00%
to 1.25%, depending upon the Variable Account Options selected, if any, on the
daily net asset value of VALIC Separate Account A is attributable to Portfolio
Director. (See "Separate Account Charges" in the prospectus)
 
     Investment Options. Under Independence Plus Contracts ten divisions of
VALIC Separate Account A are available variable investment alternatives, each
investing in shares of a different underlying fund of the Series Company
portfolio. The ten mutual funds are managed by the Company for advisory fees at
annual rates ranging from .28% to .50% of each respective portfolio's average
daily net assets. In addition, two fixed investment options are available. Under
Portfolio Director, sixteen divisions of VALIC Separate Account A are available,
thirteen of which invest in a different investment portfolio of the Series
Company and three divisions of which invest in other mutual fund portfolios.
These mutual fund portfolios are managed either by the Company, the Dreyfus
Corporation, or Templeton Investment Counsel Inc. for advisory fees at annual
rates ranging from .28% to .90% of each portfolio's or mutual fund's average
daily net assets. Two fixed investment options are also available.
 
     Annuity Options. Annuity options under Independence Plus Contracts provide
for payments on a fixed or variable basis, or a combination of both. The
Independence Plus Contract permits annuity payments for a designated period
between 3 and 30 years on a fixed basis only. Portfolio Director permits annuity
payments for a designated period between of 5 and 30 years on a fixed basis
only. Independence Plus Contracts and Portfolio Director both provide for
"betterment of rates." Under this provision, annuity payments for fixed
annuities will be based on mortality tables then being used by the Company, if
more favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM V-PLAN CONTRACTS
 
     Sales/Surrender Charges. Under a V-Plan Contract, no sales charge is
deducted at the time a Purchase Payment is made, but a surrender charge may be
imposed on partial or total surrenders. The surrender charge is equal to 7% of
the Purchase Payments withdrawn within five years of the date such Purchase
Payments were made. The most recent Purchase Payments are deemed to be withdrawn
first. Up to 10% of the account value may be surrendered in a Participant Year
without any surrender charge being imposed. Portfolio Director also imposes a
surrender charge upon total or partial surrenders. However, the surrender charge
under Portfolio Director may not exceed 5% of any Purchase Payments withdrawn
within the most recent five years prior to the receipt of the surrender request
by the Company at its Home Office. V-Plan Contracts have other provisions where
surrender charges are not imposed. However, Portfolio Director provides at least
two additional provisions, not included in V-Plan Contracts, under which no
surrender charge will be imposed. Those Portfolio Director provisions include no
surrender charges on an election of the no charge systematic withdrawal method,
and where an employee-participant has maintained the account for a period of
five years and has attained the age 59 1/2. (See "Surrender Charge" in the
prospectus.) For purposes of satisfying the fifteen-year and five-year holding
requirements, Portfolio Director will be deemed to have been issued on the same
date as the V-Plan Contract or certificate thereunder, but no earlier than
January 1, 1982.
 
     If there is a total or partial surrender, Purchase Payments exchanged into
Portfolio Director and which were made within five years before the date of
exchange will be treated as Purchase Payments under Portfolio Director for
purposes of calculating the surrender charge. Exchanged payments will be deemed
to have been made under Portfolio Director on the date they were made to the
V-Plan Contract for purposes of calculating the surrender charge under Portfolio
Director.
 
     Other Charges. There are no administrative and risk charges under V-Plan
Contracts. For Portfolio Director, a quarterly account maintenance fee of $3.75
is assessed for each calendar quarter during the Purchase Period during which
any Variable Account Option Account Value is credited to a Participant's
Account. The fee is to reimburse the Company for some of the administrative
expenses associated with the Variable Account Options. No fee is assessed for
any calendar quarter if the Account Value is credited only to the Fixed Account
Options throughout the quarter. Such fees begin immediately if an exchange is
made into any Variable Account Option offered under Portfolio Direc-
 
                                       15
<PAGE>   789
 
tor. The fee may also be reduced or waived by the Company on Portfolio Director
if the administrative expenses are expected to be lower for that Contract. (See
"Reduction or Waiver of Account Maintenance Fee, Surrender, Mortality and
Expense Risk Fee or Administration and Distribution Fee Charges" in the
prospectus.) To cover expenses not covered by the account maintenance fee and to
compensate the Company for assuming mortality risks and administration and
distribution expenses under Portfolio Director, an additional daily charge with
an annualized rate of 1.00% to 1.25%, depending upon the Variable Account
Options selected, if any, on the daily net asset value of the VALIC Separate
Account A is attributable to Portfolio Director. (See "Separate Account Charges"
in the prospectus.)
 
     Investment Options. There are no variable investment alternatives provided
under V-Plan Contracts.
 
     Annuity Options. Annuity options under V-Plan Contracts provide for
payments on a fixed basis only. The V-Plan Contract permits annuity payments for
a designated period of 1 to 15 years. Under a V-Plan Contract, the designated
period option may, subject to adverse tax consequences, be commuted at any time
for its remaining value. Portfolio Director permits Payout Payments for a
designated period of between 5 and 30 years on a fixed basis only. Under
Portfolio Director, Payout Payments may be made on a fixed or variable basis, or
a combination of both. Portfolio Director does not provide for commutation.
V-Plan Contracts and Portfolio Director both provide for "betterment of rates."
Under this provision, Payout Payments for fixed annuities will be based on
mortality tables then being used by the Company, if more favorable to the
Annuitant than those included in the Contract.
 
EXCHANGES FROM SA-1 AND SA-2 CONTRACTS
(GUP-64, GUP-74, GTS VA CONTRACTS)
 
     Sales/Surrender Charges. Under the SA-1 and SA-2 Contracts a sales and
administrative charge is deducted from each Purchase Payment. This charge ranges
from 5% of the first $5,000 of Purchase Payments to 3% of Purchase Payments in
excess of $15,000. If a SA-1 or SA-2 Contract is exchanged for Portfolio
Director the surrender charge under Portfolio Director will not apply to the
amount of Account Value applied to Portfolio Director ("Exchanged Amount").
Purchase Payments made to Portfolio Director, however, would be subject to a
surrender charge. In the case of a partial surrender, all Purchase Payments to
Portfolio Director will be deemed to be withdrawn before any Exchanged Amount is
deemed to be withdrawn. No exchange pursuant to this offer will be allowed
within 120 days of a transfer of fixed accumulations under a SA-1 or SA-2
Contract to the variable portion of such Contract. Under Portfolio Director, no
sales charge is deducted at the time a Purchase Payment is made, but a surrender
charge may be imposed on partial or total surrenders. The surrender charge may
not exceed 5% of any Purchase Payments withdrawn within the most recent five
years prior to the receipt of the surrender request by the Company at its Home
Office. For purposes of this surrender charge, the most recent Purchase Payments
are deemed to be withdrawn first. (See "Surrender Charge" in the prospectus.)
 
     Other Charges. A charge of a percentage of each Purchase Payment is made
for administrative expenses for SA-1 and SA-2 Contracts. The charge is generally
1.25% and is included in the above sales and administrative charge. An
additional daily charge (at an annual rate of 1% of total net assets
attributable to SA-1 Contracts and ranging from .21% to .85% of total net assets
attributable to SA-2 Contracts) is made for mortality and expense risks assumed
by the Company under the variable portion of the Contract. The total of these
expenses and other charges is limited to a maximum of the rate imposed on SA-1
and SA-2 Contracts on April 1, 1987. (See prospectus for SA-1 and SA-2 contracts
dated April 20, 1987.) For Portfolio Director, a quarterly account maintenance
fee of $3.75 is assessed for each calendar quarter during the Purchase Period
during which any Variable Account Option Account Value is credited to a
Participant's Account. The fee is to reimburse the Company for some of the
administrative expenses associated with the Variable Account Options. No fee is
assessed for any calendar quarter if the Account Value is credited only to the
Fixed Account Options throughout the quarter. Such fee begins immediately if an
exchange is made into any Variable Account Option offered under Portfolio
Director. The fee may also be reduced or waived by the Company on Portfolio
Director if the administrative expenses are expected to be lower for that
Contract. (See "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk

Fee or Administration and Distribution Fee Charges" in the prospectus.) To cover
expenses not covered by the account maintenance fee and to compensate the
Company for assuming mortality risks and administration and distribution
expenses under Portfolio Director, an additional daily charge with an annualized
rate of 1.00% to 1.25%, depending upon the Variable Account Options selected, if
any, on the average daily net asset value of the Separate Account is
attributable to Portfolio Director. (See "Separate Account Charges" in the
prospectus.)
 
     Investment Options. Under SA-1 and SA-2 Contracts only one division of
VALIC Separate Account A is available as a variable investment alternative. This
division invests in a portfolio of the Series Company. This portfolio is managed
by the Company for advisory fees at an annual rate of .29% of the portfolio's
average daily net assets. (Under a "grandfathering" arrangement, the total
advisory fees and certain other charges imposed against these Contracts are
limited to a maximum of the rate charged on April 1, 1987. See the prospectus
for these Contracts dated April 20, 1987.) Under Portfolio Director, sixteen
divisions of VALIC Separate Account A are available, thirteen of which invest in
a different investment portfolio of the Series Company and three divisions of
which invest in other mutual fund portfolios. These mutual fund portfolios are
managed by either the Company, The Dreyfus Corporation, or Templeton Investment
Counsel Inc., for advisory fees at annual rates ranging from .28% to .90% of
each portfolio's or mutual fund's average daily net assets. Additionally, two
fixed investment options are available under Portfolio Director.
 
     Annuity Options. Annuity options under the SA-1 and SA-2 Contracts provide
for payments on a fixed or variable basis, or a combination of both. The SA-1
Contract annuity payments under a designated period option are limited to 15
years on a fixed basis only. Under this Contract, the designated period option
may, subject to adverse tax consequences, be commuted at any time for its
remaining value. SA-2 Contracts do not provide a designated period option nor do
they provide for commutation. Portfolio Director permits Payout Payments for a
designated period of between 5 and 30 years on a fixed basis only. Portfolio
Director does not provide for commutation. The SA-1 and SA-2 Contracts make no
provision for transfers from a separate account to a fixed annuity during the
annuity period. This option, subject to certain conditions, is available under
Portfolio Director. The SA-1 Contracts provide an option for monthly variable
annuity payments to be made at a level payment basis during each year of the
annuity period. Portfolio Director does not provide this option. SA-1 and
Portfolio Director, but not SA-2 Contracts, both provide for "betterment of
rates." Under this provision, Payout Payments for fixed annuities will be based
on mortality tables then being used by the Company, if more favorable to the
Annuitant than those included in the Contract.
 
EXCHANGES FROM IMPACT CONTRACTS
 
     Sales/Surrender Charges. Under an Impact Contract, no sales charge is
deducted at the time a Purchase Payment is made, but a surrender charge may be
imposed on partial or total surrenders. The surrender charge is equal to 5% of
the Purchase Payments withdrawn within three years of the date such Purchase
Payments were made. The most recent Purchase Payments are deemed to be withdrawn
first. Portfolio Director also imposes a surrender charge upon total or partial
surrenders which may not exceed 5% of any Purchase Payments withdrawn within the
most recent five years prior to the receipt of the surrender request by the
Company at its Home Office. Portfolio Director also has other provisions where
surrender charges are not imposed. (See "Exceptions to Surrender Charge" in the
prospectus.) For purposes of satisfying the fifteen-year and five-year holding
requirements, Portfolio Director will be deemed to have been issued on the same
date as the Impact Contract, or certificate thereunder, but no earlier than
January 1, 1982. Only Purchase Payments exchanged into a Portfolio Director
which were made within three years before the date of exchange will be treated
as Purchase Payments under Portfolio Director for purposes of calculating the
surrender charge. Exchanged payments will be deemed to have been made under
Portfolio Director on the date they were made to Impact Contracts for purposes
of calculating the surrender charge under Portfolio Director.
 
     Other Charges. Under Impact Contracts, a $30 annual charge is assessed once
a year to cover administrative expenses. The charge may, with prior regulatory
approval if required, be increased or decreased. In addition, a daily charge is
made at an annual rate of 1% of the net asset value allocable to the Impact
Contracts to cover administrative expenses (other than those covered by the
annual
                                       17
<PAGE>   791
 
charge) and mortality risks assumed by the Company. For Portfolio Director, a
quarterly account maintenance fee of $3.75 is assessed for each calendar quarter
during the Purchase Period during which any Variable Account Option Account
Value is credited to a Participant's Account. The fee is to reimburse the
Company for some of the administrative expenses associated with the Variable
Account Options. No fee is assessed for any calendar quarter if the Account
Value is credited only to the Fixed Account Options throughout the quarter. Such
fee begins immediately if an exchange is made into any Variable Account Option
offered under Portfolio Director. The fee may also be reduced or waived by the
Company on Portfolio Director if the administrative expenses are expected to be
lower for that Contract. (See "Reduction or Waiver of Account Maintenance Fee,
Surrender, Mortality and Expense Risk Fee or Administration and Distribution Fee
Charges" in the prospectus.) To cover expenses not covered by the account
maintenance fee and to compensate the Company for assuming mortality risks and
administration and distribution expenses under Portfolio Director, an additional
daily charge with an annualized rate of 1.00% to 1.25%, depending upon the
Variable Account Options selected, if any, on the daily net asset value of the
Separate Account is attributable to Portfolio Director. (See "Separate Account
Charges" in the prospectus.)
 
     Investment Options. Under the Impact Contract five divisions of Separate
Account A are available as variable investment alternatives, each investing in
shares of a different underlying fund of the Series Company portfolio. The five
mutual funds are managed by the Company for advisory fees at annual rates
ranging from .28% to .50% of each respective portfolio's average daily net
assets. Under Portfolio Director, sixteen divisions of VALIC Separate Account A
are available, thirteen of which invest in a different investment portfolio of
the Series Company and three divisions of which invest in other mutual fund
portfolios. These mutual fund portfolios are managed by either the Company, The
Dreyfus Corporation, or Templeton Investment Counsel Inc., for advisory fees at
annual rates ranging from .29% to .90% of each portfolio's or mutual fund's
average daily net assets. In addition, two fixed investment options are
available under Portfolio Director.
 
     Annuity Options. Annuity options under Impact Contracts provide for
payments on a fixed or variable basis, or a combination of both. The Impact
Contract permits annuity payments for a designated period of 1 to 15 years on a
fixed basis only. Under an Impact Contract, the designated period option may,
subject to adverse tax consequences, be commuted at any time for its remaining
value. Portfolio Director permits Payout Payments for a designated period of
between 5 and 30 years on a fixed basis only. Portfolio Director does not
provide for commutation. Impact Contracts and the Portfolio Director both
provide for "betterment of rates." Under this provision, Payout Payments for
fixed annuities will be based on mortality tables then being used by the
Company, if more favorable to the Annuitant than those included in the Contract.
 
EXCHANGES FROM COMPOUNDER CONTRACTS
 
     Sales/Surrender Charges. Under a Compounder Contract a sales and
administrative charge is deducted from each Purchase Payment. This charge ranges
from 5% of the first $5,000 of Purchase Payments to 3% of Purchase Payments in
excess of $15,000. If a Compounder Contract is exchanged for Portfolio Director
the surrender charge under Portfolio Director will not apply to the amount of
Account Value applied to Portfolio Director. Purchase Payments made to Portfolio
Director, however, would be subject to the surrender charge under Portfolio
Director. In the case of a partial surrender, all Purchase Payments to Portfolio
Director will be deemed to be withdrawn before any Exchanged Amount is deemed to
be withdrawn. Under Portfolio Director, no sales charge is deducted at the time
a Purchase Payment is made, but a surrender charge may be imposed on partial or
total surrenders. The surrender charge may not exceed 5% of any Purchase
Payments withdrawn within the most recent five years prior to the receipt of the
surrender request by the Company at its Home Office. For purposes of this
surrender charge, the most recent Purchase Payments are deemed to be withdrawn
first. (See "Surrender Charge" in the prospectus.)
 
     Other Charges. A charge of a percentage of each Purchase Payment is made
for administrative expenses under a Compounder Contract. The charge is 1.25% and
is included in the above sales charge. For Portfolio Director, a quarterly
account maintenance fee of $3.75 is assessed for each calendar quarter during
the Purchase Period during which any Variable Account Option Account Value is
credited to a Participant's Account. The fee is to reimburse the Company for
some of the administra-
                                       18
<PAGE>   792
 
tive expenses associated with the Variable Account Options. No fee is assessed
for any calendar quarter if the Account Value is credited only to the Fixed
Account Options throughout the quarter. Such fee begins immediately if an
exchange is made into any Variable Account Option offered under Portfolio
Director. The fee may also be reduced or waived by the Company for Portfolio
Director if the administrative expenses are expected to be lower for that
Contract. (See "Reduction or Waiver of Account Maintenance Fee, Surrender,
Mortality and Expense Risk Fee or Administration and Distribution Fee Charges"
in this prospectus.) To cover expenses not covered by the account maintenance
fee and to compensate the Company for assuming mortality risks and
administration and distribution expenses under Portfolio Director, an additional
daily charge with an annualized rate of 1.00% to 1.25%, depending upon the
Variable Account Options selected, if any, on the daily net asset value of the
Separate Account is attributable to Portfolio Director. (See "Separate Account
Charges" in the prospectus.)
 
     Investment Options. There are no variable investment alternatives provided
under Compounder Contracts.
 
     Annuity Options. Payout Payments under a Compounder Contract are on a fixed
basis only and the designated period option is limited to a period of 15 years.
However, under a Compounder Contract, the designated period option may, subject
to adverse tax consequences, be commuted at any time for its remaining value.
Portfolio Director allows Payout Payments be made on a fixed or variable basis,
or both. One option under the Portfolio Director provides for a designated
period of 5 and 30 years on a fixed basis only. Portfolio Director does not
provide for commutation. Unlike Portfolio Director, the Compounder Contracts
contain no "betterment of rates" provision.
 
INFORMATION WHICH MAY BE APPLICABLE TO
ANY EXCHANGE
 
     Guaranteed Annuity Rates. Mortality rates have improved since annuity rates
were developed for the other contracts. Therefore, the annuity rates guaranteed
in Portfolio Director are less favorable to Contract Owners and Annuitants than
those guaranteed in the other contracts. However, the current annuity rates
being charged for fixed annuities under the "betterment of rates" provisions
discussed above are more favorable than those guaranteed under Portfolio
Director or the other contracts. Of course, no assurance can be given that this
will continue to be true at the time of annuitization for a given contract.
Guaranteed annuity rate tables are set forth in your Contract or in current
endorsements thereto. Those guaranteed for Portfolio Director are set forth
therein, and copies may be obtained from one of the Company's Regional Offices
listed on the inside back cover of this prospectus.
 
     To satisfy a Federal tax law requirement, non-spouse beneficiaries under
Portfolio Director generally must receive the entire benefit payable upon the
death of the Annuitant over their life expectancy or within five years of the
Annuitant's death. This requirement may be inapplicable to certain other
contracts or certificates issued before January 19, 1985 if not exchanged.

     a. Since this is the first partial surrender in this participant year,
        calculate the excess over 10% of the value of the Purchase Units
 
       10% of $39,000 = $3,900 [no charge on this 10% withdrawal]
 
     b. The Account Value upon which Surrender Charge on the Full Surrender may
        be calculated (levied) is $39,000 - $3,900 = $35,100
 
     c. The Surrender Charge calculated on the Account Value withdrawn $35,100 X
        .05 = $1,755
 
     d. Since only $29,000 has been paid in Purchase Payments in the 60 months
        prior to the Full Surrender, the charge can only be calculated on
        $29,000. The $3,900 partial withdrawal does not reduce this amount.
        Thus, the charge is $29,000 X (0.05) = $1,450.

     The current yield quotation above is based on the seven days ended December
31, 1998, the date of the most recent balance sheet included in the registration
statement ("base period"). It is computed by determining the net change,
exclusive of capital changes, in the value of a hypothetical pre-existing
account having a balance of one Purchase Unit at the beginning of the period,
subtracting a hypothetical charge reflecting deductions from Contract Owner
accounts, and dividing the difference by the value of the account at the
beginning of the base period to obtain the base period return and then
multiplying the base period return by 365/7.

                   CALCULATION OF AVERAGE ANNUAL TOTAL RETURN
 
     Average Annual Total Return quotations for the 1, 3, 5, and 10 year periods
ended December 31, 1998, the date of the most recent balance sheet included in
this registration statement, are computed by finding the average annual com-
 
pounded rates of over the 1, 3, 5, and 10 year periods that would equate the
initial amount invested to the ending redeemable value, according to the
following formula:
 
                                 P (1+T)n = ERV
 
     Where:
 
<TABLE>
                 <S>     <C>
                 P     = a hypothetical initial Purchase Payment of $1,000
                 T     = average annual total return
                 n     = number of years
                 ERV =   redeemable value at the end of the 1, 3, 5 or 10 year
                         periods of a hypothetical $1,000 Purchase Payment made at
                         the beginning of the 1, 3, 5, or 10 year periods (or
                         fractional portion thereof)
</TABLE>
 
     The Company may advertise standardized average annual total return which,
includes the surrender charge of up to 5% of Gross Purchase Payments received
during the most recent 60 months as well as non-standardized average annual
total returns which does not include a surrender charge or maintenance fee.
 
     There is no sales charge for reinvested dividends. All recurring fees have
been deducted. For fees which vary with the account size, an account size equal
to that of the median account size has been assumed. Ending redeemable value has
been determined assuming a complete redemption at the end of the 1, 3, 5 or 10
year period and deduction of all nonrecurring charges at the end of each such
period.
 
                            PERFORMANCE INFORMATION
 
HYPOTHETICAL $10,000 ACCOUNT VALUE AND
CUMULATIVE RETURN AS COMPARED TO BENCHMARKS TABLES.
 
     The following tables show the Hypothetical $10,000 Account Value and
Cumulative Return for each Division as compared to the benchmarks shown.
 
     These performance calculations for the Divisions, and the methods used for
calculating them, are explained in the prospectus. (See "How To Review
Investment Performance of Separate Account Divisions" and "Variable Account
Options" in the prospectus.)
 
     These tables compare hypothetical investment performance and percentage
changes in Purchase Unit values with the results of several benchmarks,
representing unmanaged market indices. The performance information has been
adjusted to reflect mortality and expense risk fees and administration and
distribution fees, net of any expense reimbursements from Dreyfus Small Cap.
Surrender charges, maintenance fees and premium taxes are not deducted. The
effect of these charges is to reduce total return to a Contract Owner. The
comparisons should be considered in light of the investment policies and
objectives of the Funds. Rates of return for the Divisions include reinvestment
of investment income, including capital gains, interest and dividends. The rates
of return on the market indices also have been adjusted to reflect reinvestment
of interest and dividends.
 
     Price returns for the market indices are calculated by subtracting the
price level at the beginning of the year from the price level at the end of the
year and dividing the difference by the price level at the beginning of the
year. To calculate dollar values for the indices' Hypothetical $10,000 Account
Value presentation, price index values were substituted for Unit values in the
calculation described in the prospectus, and where applicable, dividend yields
were then added to determine the total returns applied in the dollar value
calculations. Similarly, to calculate Cumulative Return for the
                                       23
<PAGE>   797
 
indices, the Cumulative Return calculation described in the prospectus for Unit
values of the Divisions is used, substituting the Hypothetical $10,000 Account
Value at the end of each year for the Purchase Unit Value. No sales load,
administrative charges, or any other expenses have been deducted from the index
calculations.
 
     Additionally, the performance of a Division may from time to time be
compared with other Indexes which have been deemed by the Company relevant to
the Division.
 
     These benchmarks do not reflect any charges for investment advisory fees,
brokerage commissions or other fees and expenses of the type charged at either
the Separate Account or Fund level. Therefore, the comparisons with these
benchmarks are of limited use.

PERFORMANCE COMPARED TO MARKET INDICES
 
     The performance of AGSPC Asset Allocation Division Five may be compared to
a benchmark comprised of a weighted average of three market sectors in which the
Division, through the AGSPC Asset Allocation Fund, will invest. The base
allocation is: 55% in equity securities, 35% in intermediate or long-term debt
securities and 10% in money market or short-term debt securities. The Division's
actual asset allocation is determined daily by the Bankers Trust Asset
Allocation Model. The performance of the equity securities sector of the
Division may be compared to the S&P 500(R) Index. The performance of the
intermediate or long-term debt securities sector may be compared to the Merrill
Lynch Corporate and Government Master Index. The Merrill Lynch Corporate and
Government Master Index consists of an index of approximately 5,000 corporate
and government bond holdings. The average maturity of these corporate bond
holdings is approximately 10 years. The performance of the money market or
short-term debt securities sector may be compared to the Certificate of Deposit
Primary Offering by New York City Banks, 30 Day Index.
 
     The performance of AGSPC Capital Conservation Division Seven may be
compared to the Merrill Lynch Corporate Master Index. The Merrill Lynch
Corporate Master Index consists of an index of approximately 4,300 corporate
bond holdings of which assets are rated AAA to BBB-. The average years to
maturity of these corporate bond holdings are approximately 12 years.
 
     Performance of AGSPC Government Securities Division Eight may be compared
to the Lehman Brothers U.S. Treasury Composite Index. The Lehman Brothers U.S.
Treasury Composite Index consists of an index of approximately 170 government
Treasury securities issues with all such issues having a maturity of greater
than one year.
 
     The performance of AGSPC Growth Division Fifteen, the AGSPC Growth & Income
Division Sixteen, AGSPC Social Awareness Division Twelve, the AGSPC Science &
Technology Division Seventeen and the AGSPC Stock Index Division Ten, may be
compared to the record of the Standard & Poor's(R) Corporation ("S&P(R)")*
Composite Stock Price Index ("S&P 500 Index"). The S&P 500(R) Index is a well
known measure of the price performance of 500 leading larger domestic stocks
which represents approximately 73% of the market capitalization of the United
States equity market. The index is an unmanaged weighted index of 500
industrial, transportation, utility and financial companies.
 
     The performance of AGSPC International Equities Division Eleven may be
compared to the Morgan Stanley Capital International Europe, Australia and Far
East Index ("EAFE Index"). The EAFE Index, which commenced in 1969, is an
unmanaged stock index consisting of approximately 1,100 companies from Europe,
Australia and the Far East. The index is capitalization weighted. It is a well
known measure for international stock performance. Total returns (with income
reinvested) for the EAFE Index are published using two methods. The first method
includes gross income (income earned without subtracting foreign income taxes
which may be withheld from foreign inves-

tors). The second method includes net income (income earned after subtracting
estimated foreign taxes). The Division currently compares its performance with
the index using the second method.
 
     The performance of the AGSPC International Government Bond Fund Division
Thirteen may be compared to the Salomon Brothers Non-US Dollar World Government
Bond Index ("Salomon Index"). Total returns with income reinvested for the
Salomon Index are published using two methods. The first method includes gross
income (income earned without subtracting foreign income taxes which may be
withheld from foreign investors). The second method includes net income (income
earned after subtracting estimated foreign taxes). The Division currently
compares its performance with the index using the second method. The Salomon
Index is an unmanaged aggregate index composed of 667 issues from sixteen
foreign countries. These countries include Austria, Australia, Belgium, Canada,
Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands,
Spain, Sweden, Switzerland and the United Kingdom.
 
     The performance of AGSPC MidCap Index Division Four may be compared to the
record of the S&P MidCap 400 Index. The S&P MidCap 400 Index was developed in
1991 by S&P to track the stock market performance of medium-capitalization
domestic stocks. The S&P MidCap 400 Index is market weighted and consists of 400
stocks of domestic companies having a median market capitalization of
approximately $1.998 billion. Stocks included in the S&P MidCap 400 Index are
chosen on the basis of their market size, liquidity and industry group
representation. No stocks included in the S&P 500 Index are included in the S&P
MidCap 400 Index.
 
     The performance of AGSPC Money Market Division Six may be compared to the
Certificate of Deposit Primary Offering by New York City Banks, 30 Day Index.
The index is a money market index which reflects the average rate paid by New
York Banks on certificates of deposit of more than $100,000. The Index for 30
days is published daily.
 
     The performance of the AGSPC Small Cap Index Division Fourteen and the
Dreyfus Small Cap Division Eighteen may be compared with the Russell 2000(R)
Index ("Russell 2000").** The Russell 2000 was developed in 1984 by the Frank
Russell Company to track the stock market performance of small capitalization
domestic stocks. The Russell 2000 is market weighted and consists of
approximately 2000 stocks. Stocks included in the Russell 2000 are chosen by the
Frank Russell Company on the basis of their market size.
 
     The performance of the Templeton Asset Allocation Division Nineteen may be
compared to a benchmark comprised of a weighted average of three market sectors.
The base allocation of the index is: 55% in equity securities, 35% in
intermediate or long-term debt securities and 10% in money market or short-term
debt securities. There are no minimum or maximum percentages as to the amount of
the fund's assets which may be invested in each of the market segments. The
performance of the equity securities sector of the Division may be compared to
the Morgan Stanley Capital International World Index ("MSCI World Index"). The
performance of the intermediate or long-term debt securities sector may be
compared to the Salomon Brothers Non-US Dollar World Government Bond Index
("Salomon World Index"). The performance of the money market or short-term debt
securities sector may be compared to the Certificate of Deposit Primary Offering
by New York City Banks, 30 Day Index. Total returns (with income reinvested) for
the MSCI World Index and the Salomon World Index are published using two
methods. The first method includes gross income (income earned without
subtracting foreign income taxes which may be withheld from foreign investors).
The second method includes net income (income earned after subtracting estimated
foreign taxes). The Division currently compares its performance with these
indexes using the second method. The MSCI World Index is an unmanaged
capitalization weighted index consisting of more than 1,500 issues from 22
countries as well as certain South African gold mining issues. The countries
include Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany,
Hong Kong, Ireland, Italy, Japan, Malaysia, The Netherlands, New Zealand,
Norway, Singapore, Spain, Sweden, Switzerland, the United Kingdom, and the
United States. The Salomon World Index is an unmanaged aggregate index composed

The Account Value of an assumed $10,000 investment in each of the Divisions is
shown in table form below. This will reflect a deduction for separate account
fees (mortality and expense risk fees plus administration and distribution fees
minus any applicable reimbursements) and underlying fund charges. This will not
reflect any deduction for account maintenance fees, surrender charges and
premium taxes. These charges would further reduce your return. See "How to
Review Investment Performance of Separate Account Divisions" in the prospectus
for information about how these returns were calculated as well as Standard
Average Annual Total Return information that reflects the deduction of all

                                PAYOUT PAYMENTS
 
ASSUMED INVESTMENT RATE
 
     The discussion concerning the amount of payout payments which follows this
section is based on an Assumed Investment Rate of 3 1/2% per annum. However, the
Company will permit each Annuitant choosing a variable payout option to select
an Assumed Investment Rate permitted by state law or regulations other than the
3 1/2% rate described in this prospectus as follows: 3%, 4 1/2%, 5% or 6% per
annum. (Note: an Assumed Investment Rate higher than 5% may not be selected
under individual Contracts.) The foregoing Assumed Investment Rates are used
merely in order to determine the first monthly payment per thousand dollars of
value. It should not be inferred that such rates will bear any relationship to
the actual net investment experience of VALIC Separate Account A.
 
AMOUNT OF PAYOUT PAYMENTS
 
     The amount of the first variable annuity payment to the Annuitant will
depend on the amount of the Account Value applied to effect the variable annuity
as of the tenth day immediately preceding the date payout payments commence, the
amount of any premium tax owed, the annuity option selected, and the age of the
Annuitant.
 
     The Contracts contain tables indicating the dollar amount of the first
payout payment under each payout option for each $1,000 of Account Value (after
the deduction for any premium tax) at various ages. These tables are based upon
the Annuity 2000 Table (promulgated by the Society of Actuaries) and an Assumed
Investment Rate of 3%, 3 1/2%, 4% and 5% per annum (3 1/2% in the group
Contract).
 
                                       37
<PAGE>   811
 
     The portion of the first monthly variable payout payment derived from a
Division of VALIC Separate Account A is divided by the Payout Unit value for
that Division (calculated ten days prior to the date of the first monthly
payment) to determine the number of Payout Units in each Division represented by
the payment. The number of such units will remain fixed during the Payout
Period, assuming the Annuitant makes no transfers of Payout Units to provide
Payout Units under another Division or to provide a fixed annuity.
 
     In any subsequent month, the dollar amount of the variable payout payment
derived from each Division is determined by multiplying the number of Payout
Units in that Division by the value of such Payout Unit on the tenth day
preceding the due date of such payment. The Payout Unit value will increase or
decrease in proportion to the net investment return of the Division or Divisions
underlying the variable payout since the date of the previous payout payment,
less an adjustment to neutralize the 3 1/2% or other Assumed Investment Rate
referred to above.
 
     Therefore, the dollar amount of variable payout payments after the first
will vary with the amount by which the net investment return is greater or less
than 3 1/2% per annum. For example, if a Division has a cumulative net
investment return of 5% over a one year period, the first payout payment in the
next year will be approximately 1 1/2 percentage points greater than the payment
on the same date in the preceding year, and subsequent payments will continue to
vary with the investment experience of the Division. If such net investment
return is 1% over a one year period, the first payout payment in the next year
will be approximately 2 1/2 percentage points less than the payment on the same
date in the preceding year, and subsequent payments will continue to vary with
the investment experience of the applicable Division.
 
     Each deferred Contract provides that, when fixed payout payments are to be
made under one of the first four payout options, the monthly payment to the
Annuitant will not be less than the monthly payment produced by the then current
settlement option rates, which will not be less than the rates used for a
currently issued single payment immediate annuity contract. The purpose of this
provision is to assure the Annuitant that, at retirement, if the fixed payout
purchase rates then required by the Company for new single payment immediate
annuity contracts are significantly more favorable than the annuity rates
guaranteed by a Contract, the Annuitant will be given the benefit of the new
annuity rates.
 
PAYOUT UNIT VALUE
 
     The value of a Payout Unit is calculated at the same time that the value of
an Purchase Unit is calculated and is based on the same values for Fund shares
and other assets and liabilities. (See "Purchase Period" in the prospectus.) The
calculation of Payout Unit value is discussed in the prospectus under "Payout
Period."
 
     The following illustrations show, by use of hypothetical examples, the
method of determining the Payout Unit value and the amount of variable annuity
payments.

                   DISTRIBUTION OF VARIABLE ANNUITY CONTRACTS
 
     The Company has qualified or intends to qualify the Contracts for sale in
all fifty states and the District of Columbia and will commence offering the
Contracts promptly upon qualification in each such jurisdiction.
 
     The Contracts are sold in a continuous offering by licensed insurance
agents who are registered representatives of broker-dealers which are members of
the National Association of Securities Dealers, Inc. (the "NASD"). The principal
underwriter for VALIC Separate Account A is A.G. Distributors, an affiliate of
VALIC. A.G. Distributors' address is 2929 Allen Parkway, Houston, Texas 77019.
A.G. Distributors is a Delaware corporation organized in 1994 and is a member of
the NASD.
 
     The licensed agents who sell the Contracts will be compensated for such
sales by commissions ranging up to 6.0% of each Purchase Payment. Managers who
supervise the agents will receive overriding commissions ranging up to 1% of
Purchase Payments. These various commissions are paid by the Company and do not
result in any charge to Contract Owners or to VALIC Separate Account A in
addition to the charges described under "Fees and Charges" in the prospectus.
 
     Pursuant to its underwriting agreement with A.G. Distributors and VALIC
Separate Account A, the Company reimburses A.G. Distributors for reasonable
sales expenses, including overhead expenses. Prior to May 1, 1999, The Variable
Annuity Marketing Company (VAMCO) was the principal underwriter for VALIC
Separate Account A. Sales commissions paid for the years 1996, 1997 and 1998
were $52,963,000, $34,105,000 and $31,109,455, respectively. VAMCO retained $0
in commissions for the years 1996, 1997 and 1998.

Report of Independent Auditors



To the Board of Directors
The Variable Annuity Life Insurance Company





         We have audited the accompanying consolidated balance sheets of The
Variable Annuity Life Insurance Company and Subsidiaries as of December 31, 1998
and 1997, and the related consolidated statements of income, changes in
stockholder's equity, comprehensive income, and cash flows for each of the three
years in the period ended December 31, 1998. These financial statements are the
responsibility of the company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

         We conducted our audits 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 statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. 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 audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of The
Variable Annuity Life Insurance Company and Subsidiaries at December 31, 1998
and 1997, and the consolidated results of their operations and their cash flows
for each of the three years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles.

                        SIGNIFICANT ACCOUNTING POLICIES

1.1  INTRODUCTION


     The Variable Annuity Life Insurance Company (VALIC), an indirect, wholly
owned subsidiary of American General Corporation (AGC), provides tax-deferred
retirement annuities and employer-sponsored retirement plans to employees of
educational, health care, public sector and not-for-profit organizations. VALIC
markets products nationwide through exclusive sales representatives.

     VALIC is 100% owned by American General Life Insurance Company (AGL), a
wholly owned subsidiary of AGC Life Insurance Company (AGC Life). AGC Life is a
wholly owned subsidiary of AGC. A summary of the accounting policies followed in
the preparation of the consolidated financial statements is set forth below.

1.2  PREPARATION OF FINANCIAL STATEMENTS

     The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles (GAAP) and include the accounts of
VALIC and its wholly owned subsidiaries. All material intercompany transactions
have been eliminated in consolidation.

     The preparation of financial statements requires management to make
estimates and assumptions that affect amounts reported in the financial
statements and disclosures of contingent assets and liabilities. Ultimate
results could differ from these estimates.

1.3  ACCOUNTING CHANGES

     COMPREHENSIVE INCOME. During 1998, VALIC adopted Statement of Financial
Accounting Standards (SFAS) 130, "Reporting Comprehensive Income," which
establishes standards for reporting and displaying comprehensive income and its
components in the financial statements. VALIC elected to report comprehensive
income and its components in a separate statement of comprehensive income.
Adoption of this statement did not change recognition or measurement of net
income and, therefore, did not impact VALIC's consolidated results of operations
or financial position.

     DERIVATIVES. In June 1998, the Financial Accounting Standards Board issued
SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," which
requires all derivative instruments to be recognized at fair value as either
assets or liabilities in the balance sheet. Changes in the fair value of a
derivative instrument are to be reported as earnings or other comprehensive
income, depending upon the intended use of the derivative instrument. This
statement is effective for years beginning after June 15, 1999. Adoption of SFAS
133 is not expected to have a material impact on VALIC's consolidated results of
operations or financial position.

1.4  INVESTMENTS

     FIXED MATURITY AND EQUITY SECURITIES. At year end, all fixed maturity and
equity securities are classified as available-for-sale and recorded at fair
value. After adjusting related balance sheet accounts as if the unrealized gains
(losses) had been realized, the net adjustment is recorded in accumulated other
comprehensive income within stockholder's equity. If the fair value of a
security classified as available-for-sale declines below its cost and this
decline is considered to be other than temporary, the security is reduced to its
fair value, and the reduction is recorded as a realized loss.

     During 1998, VALIC maintained a trading portfolio of certain fixed maturity
securities. Trading securities are recorded at fair value. Unrealized gains
(losses), as well as realized gains (losses), are included in net investment
income. VALIC held no trading securities at December 31, 1998, and trading
securities did not have a material effect on net investment income.

     MORTGAGE LOANS. Mortgage loans are reported at amortized cost, net of an
allowance for losses. The allowance for losses covers all non-performing loans
and loans for which management has a concern based on its assessment of risk
factors, such as potential non-payment or non-monetary default. The allowance is
based on a loan-specific review and a formula that reflects past results and
current trends.

     Loans for which VALIC determines that collection of all amounts due under
the contractual terms is not probable are considered to be impaired. VALIC
generally looks to the underlying collateral for repayment of impaired loans.
Therefore, impaired loans are considered to be collateral dependent and are
reported at the lower of amortized cost or fair value of the underlying
collateral, less estimated costs to sell.

     POLICY LOANS. Policy loans are reported at unpaid principal balance.

     INVESTMENT INCOME. Interest on fixed maturity securities and performing
mortgage loans is recorded as income when earned and is adjusted for any
amortization of premium or discount. Interest on delinquent mortgage loans is
recorded as income when received. Dividends are recorded as income on
ex-dividend dates.

     REALIZED INVESTMENT GAINS (LOSSES). Realized investment gains (losses) are
recognized using the specific identification method.

1.5  DERIVATIVES RELATED TO INVESTMENTS

     VALIC's use of derivative financial instruments is generally limited to
interest rate and currency swap agreements, and options to enter into interest
rate swap agreements (call swaptions). VALIC accounts for its derivative
financial instruments as hedges.

     INTEREST RATE AND CURRENCY SWAP AGREEMENTS. Interest rate swap agreements
are used to convert specific investment securities from a floating-rate to a
fixed-rate basis, or vice versa. Currency swap agreements are used to convert
cash flows from specific investment securities denominated in foreign currencies
into U.S. dollars at specified exchange rates, and to hedge against currency
rate fluctuations on anticipated security purchases.

1.5  DERIVATIVES RELATED TO INVESTMENTS-(CONTINUED)

     The difference between amounts paid and received on swap agreements is
recorded on an accrual basis as an adjustment to investment income over the
periods covered by the agreements. The related amount payable to or receivable
from counterparties is included in other liabilities or assets.

     The fair values of swap agreements are recognized in the consolidated
balance sheet if they hedge investments carried at fair value or if they hedge
anticipated purchases of such investments. In this event, changes in the fair
value of a swap agreement are reported in accumulated other comprehensive income
included in stockholder's equity, consistent with the treatment of the related
investment security.

     For swap agreements hedging anticipated investment purchases, the net swap
settlement amount or unrealized gain or loss is deferred and included in the
measurement of the anticipated transaction when it occurs.

     Swap agreements generally have terms of two to ten years. Any gain or loss
from early termination of a swap agreement is deferred and amortized into income
over the remaining term of the related investment. If the underlying investment
is extinguished or sold, any related gain or loss on swap agreements is
recognized in income.

     Swaptions. Options to enter into interest rate swap agreements are used to
limit VALIC's exposure to reduced spreads between investment yields and interest
crediting rates should interest rates decline significantly over prolonged
periods.

     During prolonged periods of decreasing interest rates, the spread between
investment yields and interest crediting rates may be reduced as a result of
minimum rate guarantees on certain insurance and annuity contracts, which limit
VALIC's ability to reduce interest crediting rates. Call swaptions, which allow
VALIC to enter into interest rate swap agreements to receive fixed rates and pay
lower floating rates, effectively maintain the spread between investment yields
and interest crediting rates during such periods.

     During prolonged periods of increasing interest rates, the spread between
investment yields and interest crediting rates may be reduced as a result of
VALIC's decision to increase interest crediting rates to limit surrenders. Put
swaptions, which allow VALIC to enter into interest rate swap agreements to pay
fixed rates and receive higher floating rates, effectively maintain the spread
between investment yields and interest crediting rates during such periods.

     Premiums paid to purchase swaptions are included in investments and are
amortized to net investment income over the exercise period of the swaptions. If
a swaption is terminated, any gain is deferred and amortized to insurance and
annuity benefits over the expected life of the insurance and annuity contracts
and any unamortized premium is charged to income. If a swaption ceases to be an
effective hedge, any gain or loss is recognized in income.

1.6  DEFERRED POLICY ACQUISITION COSTS (DPAC)

     Certain costs of writing an insurance policy, including commissions,
underwriting and marketing expenses, are deferred and reported as DPAC. DPAC is
charged to expense in relation to the estimated gross profits of the insurance
contracts, including realized gains (losses).

     DPAC is adjusted for the impact on estimated future gross profits as if net
unrealized gains (losses) on securities had been realized at the balance sheet
date. The impact of this adjustment is included in accumulated other
comprehensive income within stockholder's equity.

     VALIC reviews the carrying value of DPAC on at least an annual basis.
Management considers estimated future gross profit margins as well as expected
mortality, interest earned and credited rates, persistency, and expenses in
determining whether the carrying amount is recoverable.

1.7  SEPARATE ACCOUNTS

     Separate Accounts are assets and liabilities associated with certain
contracts, principally annuities for which the investment risk lies solely with
the holder of the contract rather than VALIC. Consequently, VALIC's liability
for these accounts equals the value of the account assets. Investment income,
realized investment gains (losses) and policyholder account deposits and
withdrawals related to Separate Accounts are excluded from the consolidated
statements of income and cash flows. Assets held in the Separate Accounts are
primarily shares in mutual funds, which are carried at fair value, based on the
quoted net asset value per share.

1.8  POLICY RESERVES

     Net deposits made by fixed annuity policyholders are accumulated at
interest rates guaranteed by VALIC plus excess interest credited at the sole
discretion of the Board of Directors until benefits are payable. Reserves for
deferred annuities (accumulation phase) are equivalent to the policyholders'
account values. Reserves for annuities on which benefits are currently payable
(annuity payout phase) are provided based upon estimated mortality and other
assumptions, including provisions for the risk of adverse deviation from
assumptions, which were appropriate at the time the contracts were issued. The
1971 Individual or Group Annuity Mortality Tables, and the 1983a Table have been
used to provide for future annuity benefits in the annuity payout phase.
Interest rates used in determining reserves for policy benefits during both the
accumulation and annuity payout phases range from 3.5% to 13.5%.

1.9  RECOGNITION OF REVENUES AND COSTS

     Premium receipts for annuity contracts are classified as deposits instead
of revenues. Revenues for these contracts consist of the mortality, expense and
surrender charges. Gains (losses) from mortality guarantees under variable
annuity contracts are recognized as they occur.

1.10 INCOME TAXES

     Deferred tax assets and liabilities are established for temporary
differences between the financial reporting basis and the tax basis of assets
and liabilities, at the enacted tax rates expected to be in effect when the
temporary differences reverse. The effect of a tax rate change is recognized in
income in the period of enactment. State income taxes are included in income tax
expense.

     A valuation allowance for deferred tax assets is provided if all or some
portion of the deferred tax asset may not be realized. An increase or decrease
in a valuation allowance that results from a change in circumstances that causes
a change in judgment about the realizability of the related deferred tax asset
is included in income. A change related to fluctuations in fair value of
available-for-sale fixed maturity securities is included in accumulated other
comprehensive income in stockholder's equity.

1.11 STATUTORY ACCOUNTING

     State insurance laws and regulations prescribe accounting practices for
calculating statutory net income and equity (capital and surplus) that differ
from GAAP. Net income and stockholder's equity as determined by statutory
accounting practices at December 31 were as follows:

1.12 COINSURANCE TRANSACTION

     On May 21, 1998, VALIC completed the acquisition of a block of individual
annuity business in a coinsurance transaction. This transaction increased assets
and insurance and annuity liabilities by $688,221.

</TABLE>

     The carrying value of investments that produced no investment income during
1998 totaled $313 or 0.001% of total invested assets. The ultimate disposition
of these assets is not expected to have a material effect on VALIC's
consolidated results of operations or financial position.

     Derivative financial instruments related to investment securities did not
have a material effect on net investment income in any of the three years ended
December 31, 1998.

                                  INCOME TAXES

5.1  TAX-SHARING AGREEMENT

     VALIC, combined with its Separate Accounts, is taxed as a life insurance
company. VALIC and the Separate Accounts are included in the consolidated life
insurance company tax return of AGC. VALIC participates in a tax-sharing
agreement with the other companies included in the consolidated return. Under
this agreement, tax payments are made to AGC as if the companies filed separate
tax returns and companies incurring operating losses and/or capital losses are
reimbursed for the use of these losses by the consolidated return group.

5.2  TAX LIABILITIES

     Components of income tax liabilities and assets at December 31 were as

     Federal income taxes paid in 1998, 1997, and 1996 were $92,613, $106,338,

                                 CAPITAL STOCK

     VALIC has two classes of capital stock: preferred stock ($1.00 par value
with 2 million shares authorized) that may be issued with such dividend,
liquidation, redemption, conversion, voting and other rights as the Board of
Directors may determine, and common stock ($1.00 par value, 5 million shares
authorized).

     VALIC is restricted by state insurance laws as to the amount it may pay as
dividends without prior approval from the Texas Department of Insurance. The
maximum dividend payout which may be made without prior approval in 1999 is
$176,753.

                                    -----------      -----------
</TABLE>


     During 1998, VALIC purchased call swaptions and put swaptions that expire
by 2000. The call swaptions had a notional amount of $950,000 and strike rates
ranging from 3.5% to 4.5% at December 31, 1998. The put swaptions had a notional
amount of $690,000 strike rates ranging from 8.0% to 8.5% at December 31, 1998.
Should the strike rates remain below market rates for call swaptions and above
market rates for put swaptions, the swaptions will expire, and VALIC's exposure
would be limited to the premiums paid. These premiums were immaterial.

     CREDIT AND MARKET RISK. Derivative financial instruments expose VALIC to
credit risk in the event of nonperformance by counterparties. VALIC limits this
exposure by entering into agreements with counterparties having high credit
ratings and by regularly monitoring the ratings. VALIC does not expect any
counterparty to fail to meet its obligation; however, nonperformance would not
have a material impact on VALIC's consolidated results of operations and
financial position.

     VALIC's exposure to market risk is mitigated by the offsetting effects of
changes in the value of the agreements and the related items being hedged.

     Carrying amounts and fair values for certain of VALIC's financial
instruments at December 31 are presented below. Care should be exercised in
drawing conclusions based on fair value, since (1) the fair values presented do
not include the value associated with all VALIC's assets and liabilities, and
(2) the reporting of investments at fair value without a corresponding
revaluation of related policyholder liabilities can be misinterpreted.

*    Includes derivative financial instruments with a fair value of $19,342 in

     The following methods and assumptions were used to estimate the fair values
of financial instruments.

     FIXED MATURITY AND EQUITY SECURITIES. Fair values of fixed maturity and
equity securities were based on quoted market prices, where available. For
investments not actively traded, fair values were estimated using values
obtained from independent pricing services or, in the case of some private
placements, by discounting expected future cash flows using a current market
rate applicable to yield, credit quality and average life of the investments.

     MORTGAGE LOANS ON REAL ESTATE. Fair value of mortgage loans was estimated
primarily using discounted cash flows, based on contractual maturities and
risk-adjusted discount rates.

     POLICY LOANS. Fair value of policy loans was estimated using discounted
cash flows and actuarially-determined assumptions, incorporating market rates.

     INSURANCE INVESTMENT CONTRACTS. Fair value of insurance investment
contracts was estimated using cash flows discounted at market interest rates.

                     TRANSACTIONS WITH AFFILIATED COMPANIES

     In the ordinary course of business, VALIC is occasionally involved in
transactions with affiliated companies. Transactions involving the purchase or
disposal of securities are consummated at the market value of the security on
the date of the transaction. Transactions with affiliated companies during each
of the three years in the period ended December 31, 1998 were as follows:

     Operating expenses include $46,556 in 1998, $22,061 in 1997, and $17,533 in
1996, for amounts paid to AGC or its subsidiaries primarily for rent, data
processing services, use of facilities and investment expenses. Interest paid on
borrowings from AGC totaled $152 in 1998, $501 in 1997, and $455 in 1996.

     On November 4, 1982, VALIC invested $11,853 in 13 1U2% Restricted
Subordinated Note due November 4, 2002 issued by AGC. The principal amount of
the note is due November 4, 2002. Principal payments of $592 were received on
November 4, 1998, 1997, and 1996. VALIC recognized $1,212 in interest income
during 1998, $1,292 for 1997, and $1,372 for 1996.

     On December 31, 1984, VALIC entered into a $48,929 note purchase agreement
with AGC. Under the agreement AGC issued an adjustable rate promissory note in
exchange for VALIC's holdings of AGC preferred stock, common stock and warrants.
The principal amount of the note is due in 20 equal installment payments
commencing December 29, 1985 and concluding December 29, 2004. Principal
payments of $2,446 were received on December 29, 1998, 1997, and 1996. VALIC
recognized $1,048, $1,296, and $1,479 of interest income on the note during
1998, 1997, and 1996, respectively.

     On May 15, 1996, VALIC sold SC Financial Corp Mortgage Notes with a book
value of $13,000 to American General Life Insurance Company of NY. Proceeds from
the sale totaled $13,033 with a profit of $33 recognized on the transaction.

     VALIC paid common stock dividends of $181,000, $50.63 per share; $379,000,
$106.01 per share; and $111,000, $31.05 per share, in 1998, 1997, and 1996,
respectively.

     VALIC received capital contributions of $55,200, $67,000, $250,000, and
$75,000 from AGL on June 30, 1998, December 31, 1998, March 31, 1997, and
December 30, 1996, respectively.

9.   TRANSACTIONS WITH AFFILIATED COMPANIES - (CONTINUED)

     VALIC acquired bonds of various issuers from American General Life and
Accident Insurance Company at a cost of $22,154 and $25,892 on January 30, 1997,
and April 8, 1997, respectively.

     On December 5, 1997, VALIC acquired bonds of various issuers from Western
National Life Insurance Company at a cost of $129,715.

                         COMMITMENTS AND CONTINGENCIES

     VALIC is a defendant in various lawsuits arising in the normal course of
business. VALIC believes it has valid defenses in these lawsuits and is
defending the cases vigorously. VALIC also believes that the total amounts that
would ultimately have to be paid arising from these lawsuits would have no
material effect on its consolidated financial position.

     All 50 states have laws requiring solvent life insurance companies to pay
assessments to state guaranty associations to protect the interests of
policyholders of insolvent life insurance companies. State guaranty fund expense
included in operating costs and expenses was $37, $30, and $2,678, for the years
ended December 31, 1998, 1997, and 1996, respectively. The accrued liability for
anticipated assessments was $4,782, $7,402, and $13,661, at December 31, 1998,
1997, and 1996, respectively. The 1998 liability was estimated by VALIC using
the latest information available from the National Organization of Life and
Health Insurance Guaranty Associations. Although the amount accrued represents
VALIC's best estimate of its liability, this estimate may change in the future.
Additionally, changes in state laws could decrease the amount recoverable
against future premium taxes.

                             EMPLOYEE BENEFIT PLANS

11.1 PENSION PLANS

     VALIC participates in several employee benefit plans which together cover
substantially all of its employees. One of these plans is a defined benefit
plan. Pension benefits under this plan are based on the participant's average
monthly compensation and length of credited service. VALIC's funding policy for
this plan is to contribute annually no more than the maximum amount that can be
deducted for federal income tax purposes.

11.1 PENSION PLANS - (CONTINUED)

     The components of pension expense and underlying assumptions for the
defined benefit plan were as follows:

     Equity and fixed maturity securities were 66% and 32%, respectively, of the
plan's assets at the plan's most recent balance sheet dates. The remaining plan
assets consisted primarily of cash equivalents and investment-related
receivables.

11.2 POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

     VALIC, through AGC, has life, medical, supplemental major medical, and
dental plans for certain retired employees and agents. Most plans are
contributory, with retiree contributions adjusted annually to limit employer
contributions to predetermined amounts. VALIC has reserved the right to change
or eliminate these benefits at any time.

11.2 POSTRETIREMENT BENEFITS OTHER THAN PENSIONS - (CONTINUED)

     The life plans are fully insured; the retiree medical and dental plans are
unfunded and self-insured. The accrued liability for postretirement benefits was
$2,388 and $1,784 at year-end 1998 and 1997, respectively. These liabilities
were discounted at the same rates used for the pension plans. Postretirement
benefit expense in 1998, 1997, and 1996 was $275, $295, and $282, respectively.

                        IMPACT OF YEAR 2000 (UNAUDITED)

     INTERNAL SYSTEMS. VALIC has numerous technology systems that are managed on
a decentralized basis. Year 2000 readiness efforts are therefore being
undertaken by its key business units with centralized oversight. Each business
unit has developed and is implementing a plan to minimize the risk of a
significant negative impact on its operations.

     While the specifics of the plans vary, the 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) reprogram or
replace systems that are not Year 2000 ready, (4) test systems to prove that
they will function into the next century as they do currently, and (5) return
the system to operations. As of December 31, 1998, these activities have been
completed for substantially all of VALIC's critical systems, making them Year
2000 ready. Vendor upgrades for a small number of systems are expected in the
first half of 1999; therefore, activities (3) through (5) are ongoing for these
systems. VALIC will continue to test its systems throughout 1999 to maintain
Year 2000 readiness.

     THIRD PARTY RELATIONSHIPS. VALIC has relationships with various third
parties who also must be Year 2000 ready. These third parties provide (or
receive) resources and services to (or from) VALIC and include organizations
with which VALIC exchanges information. Third parties include vendors of
hardware, software, and information services; providers of infrastructure
services such as voice and data communications and utilities for office
facilities; investors; customers; distribution channels; and joint venture
partners. Third parties differ from internal systems in that VALIC exercises
less, or no, control over their Year 2000 readiness. VALIC has developed a plan
to assess and attempt to mitigate the risks associated with the potential
failure of third parties to achieve Year 2000 readiness. The plan includes the
following activities: (1) identify and classify third party dependencies; (2)
research, analyze, and document Year 2000 readiness for critical third parties;
and (3) test critical hardware and software products and electronic interfaces.
A more detailed evaluation will be completed during first quarter 1999 as part
of VALIC's contingency planning efforts. Due to the various stages of third
parties' Year 2000 readiness, VALIC's testing activities will extend throughout
1999.

     CONTINGENCY PLANS. VALIC has commenced contingency planning to reduce the
risk of Year 2000 related business failures. The contingency plans, which
address both internal systems and third party relationships, include the
following activities: (1) evaluate the consequences of failure of business
processes with significant exposure to Year 2000 risk, (2) determine the
probability of a Year 2000-related failure for those processes that have a high
consequence of failure; (3) develop an action plan to complete contingency plans
for those processes that rank high in consequence and probability of failure;
and (4) complete the applicable action plans. VALIC is currently developing
contingency plans and expects to substantially complete all contingency-planning
activities by April 30, 1999.

     RISKS AND UNCERTAINTIES. Based on its plans to make internal systems ready
for Year 2000, to deal with third party relationships, and to develop
contingency actions, VALIC believes that it will experience, at most, isolated
and minor disruptions of business processes following the turn of the century.
Such disruptions are not expected to have a material effect on VALIC's future
results of operations, liquidity, or financial condition. However, due to the
magnitude and complexity of this project, risks and uncertainties exist and
VALIC is not able to predict a most reasonably likely worst case scenario. If
Year 2000 readiness is not achieved due to nonperformance by significant third
party vendors, VALIC's failure to maintain critical systems as Year 2000 ready,
failure of critical third parties to achieve Year 2000 readiness on a timely
basis, or other unforeseen circumstances in completing VALIC's plans, the Year
2000 issues could have a material adverse impact on VALIC's operations following
the turn of the century.

     COSTS. Through December 31, 1998, VALIC has incurred and expensed $27
million (pretax) related to Year 2000 readiness, including $20 million incurred
during 1998. VALIC currently anticipates that it will incur future costs of
approximately $2 million (pretax) to maintain Year 2000 readiness, complete Year
2000 work on noncritical systems and third party relationships, and complete
contingency planning activities. In addition, VALIC accelerated the planned
replacement of certain systems as part of the Year 2000 plans.

                                CHAIRMAN'S LETTER                              1
================================================================================



TO OUR PARTICIPANTS:

We are pleased to present the December 31, 1998, Annual Report to Contract
Owners for Separate Account A of The Variable Annuity Life Insurance Company. A
summary of the change in unit value for each fund and each product series
(Portfolio Director 1, Portfolio Director 2, Portfolio Director Plus,
Independence Plus, Group Unit Purchase and Impact) appears on pages two and
three.

1998 was a volatile year for investors around the world. Problems that began in
Asia in late 1997 circled the globe throughout 1998. Central banks, fearing the
worst lowered interest rates in the fourth quarter of 1998. The result was an
unexpected and dramatic rise in stock and bond prices worldwide.

The year was marked by extreme flight to quality. Investors general preference
was for larger cap growth in stocks over small cap value stocks, and U.S.
Treasury Securities.

The Standard & Poor's 500 Index, dominated by large cap, high-growth technology
and global consumer product companies, had a total return of 28.58%. The top 15
stocks alone accounted for half of the performance. It was a difficult year for
active equity fund managers, as almost 90% of the active managers lagged the S&P
500 Index returns. Also, the S&P 500 Index returns for the year outperformed
over 71% of all U.S.-traded common stocks. The medium to small-cap companies
lagged, with the large companies S&P MidCap 400 Index returning 6.27% and the
S&P SmallCap 600 Index, producing a negative 1.31%.

There was a greater variability in returns between growth and value components
of the equity indices. In the large capitalization arena, S&P 500/BARRA Growth
Index returned an outstanding 42.16%, while the S&P 500/BARRA Value Index
returned 14.67%. In the mid-cap sector, the S&P 400/BARRA Growth Index returned
34.86% compared to the S&P 400/BARRA Value Index return of 4.67%. However, the
small cap equity returns experienced wide variability, with the S&P SmallCap
600/BARRA Growth Index returning 2.29%, and the S&P SmallCap 600/BARRA Value
returning a negative 5.06%.

Globally, the pattern of investment results was very similar to the U.S. equity
returns. The MSCI world Index returned 22%. The top quintile of growth stocks
outperformed the bottom quintile of value stocks by over two times with returns
of 48% and 17%, respectively.

The yield on the 30 year Treasury bond opened the year at 5.92% and declined to
5.10% by the end of 1998, as the Federal Reserve lowered the federal fund rate
three times between September 29 and November 17, leaving the target rate at
4.75%.

For the year, the bond market return, reflected in the Lehman Aggregate Bond
Index, was 8.69% with the long U.S. Treasury Index showing the highest return of
13.52%, followed by the Long Corporate AA/Better Index 10.52%, and the High
Yield Index with 1.60%. Throughout the developed world international bond prices
appreciated as yields declined.

While international markets outside of North America and Europe remain
unsettled, the U.S. economy is experiencing unprecedented prosperity and growth.
Furthermore, with worldwide inflation rates low, and the Federal Reserve weary
of weakness in Asia and emerging markets, it appears that we can expect a
continuation of the current stable rate environment.

If you have any questions about your contract or this report, we would be happy
to hear from you.

                                  Respectfully,


                                  /s/ THOMAS L. WEST, JR.


                                  Thomas L. West, Jr., Chairman 
                                  The Variable Annuity Life Insurance Company

NOTE B -- SUMMARY OF SIGNIFICANT 
          ACCOUNTING POLICIES

         The assets of the Separate Account are part of VALIC. The following is
a summary of significant accounting policies consistently followed by the
Separate Account in the preparation of its financial statements.

         USE OF ESTIMATES. The financial statements have been prepared in
conformity with generally accepted accounting principles. The preparation of
financial statements requires management to make estimates and assumptions that
affect amounts reported in the financial statements and disclosure of contingent
assets and liabilities. Ultimate results could differ from these estimates.

         INVESTMENT VALUATION. Investments in mutual funds (the "Funds") are
valued at the net asset (market) value per share at the close of each business
day as reported by each Fund.

         INVESTMENT TRANSACTIONS. Investment transactions are accounted for on
the trade date. Realized gains and losses on investments are determined on the
basis of identified cost. Capital gain distributions from mutual funds are
recorded on the ex-dividend date and reinvested upon receipt.

         INVESTMENT INCOME. Dividend income from mutual funds is recorded on
the ex-dividend date and reinvested upon receipt.

         ANNUITY RESERVES. Net purchase payments made by variable annuity
contract owners are accumulated based on the performance of the investments of
the Separate Account until the date the contract owners select to commence
annuity payments. Reserves for annuities on which benefits are currently payable
are provided for based upon estimated mortality and other assumptions, including
provisions for the risk of adverse deviation from assumptions, which were
appropriate at the time the contracts were issued. The 1983(a) Individual
Mortality Table, the Annuity 2000 Mortality Table, and the 1994 Group Annuity
Reserve Mortality Table have been used in the computation of annuity reserves
for currently payable contracts. Participants are able to elect assumed
investment rates between 3.0% and 6.0%, as regulated by the applicable state
laws.

         ACCUMULATION UNITS. VALIC offers both standard and enhanced contracts.
These contracts may have different Separate Account charges.

NOTE C -- TRANSACTIONS WITH AFFILIATES

         VALIC serves as investment advisor ("the Advisor"), transfer agent, and
accounting services agent to AGSPC and AGSPC 3. American General Investment
Management, LLP, an affiliate of the Advisor, serves as investment sub-advisor
to certain AGSPC 3 mutual funds.

         The Separate Account is charged for mortality and expense risks
assumed by VALIC and for distribution and administrative services provided by
VALIC. The standard charge, based on the daily net assets of each division, is
assessed daily based on the following annual rates: for Division 10B, 0.85% on
the first $10,000,000, 0.425% on the next $90,000,000, and 0.21% on the excess
over $100,000,000; for Divisions 1,2,4 through 8, 10A, 10C and 10D, 11 through
17, 33 through 44, 48 through 50, and 58 through 60, 1.00%; and for Divisions
18 through 32, and 51 through 54, 1.25%. Certain mutual funds reimburse to
VALIC a portion of the distribution or administrative costs associated with
offering their funds through a VALIC annuity contract. VALIC, in turn reduces
the Separate Account charge to that division by the amount of the
reimbursement. The expense reduction is credited daily based on the following
annual rates: for Divisions 21 through 23, 26 through 30, 32 through 44, 48
through 50, and 58 through 60, 0.25%; for Division 31, 0.24% (effective
December 8, 1997, the expense reduction for Division 31 became 0.20% on the
first $75,000,000, and 0.25% on the excess over $75,000,000); and for Division
18, 0.15% (commencing July 1, 1997). Separate Account charges may be reduced if
contracts are issued to certain types of plans that are expected to result in
lower costs to VALIC. Consequently, each division may offer separate "classes"
of units of beneficial interest reflecting reductions in separate account
charges.

         Pursuant to the reorganization agreement entered into on April 17,
1987, which transferred VALIC Separate Accounts One and Two into Separate
Account A Divisions 10A and 10B, respectively, expenses of each division (as
defined to include underlying mutual fund expenses) are limited to the
following rates based on average daily net assets: Division 10A, 1.4157% on the
first $359,065,787, 1.36% on the next $40,934,213, and 1.32% on the excess over
$400,000,000; Division 10B, 0.6966% on the first $25,434,267, 0.5% on the next
$74,565,733, and 0.25% on the excess over $100,000,000. Accordingly, during the
years ended December 31, 1998 and 1997, VALIC reduced expenses of Division 10B
by $82,027 and $85,996, respectively.

         A portion of the annual contract maintenance charge is assessed on
each contract (except those relating to Divisions 10A and 10B) by VALIC on the
last day of the calendar quarter in which VALIC receives the first purchase
payment, and in quarterly installments thereafter during the accumulation
period. Maintenance charges assessed totaled $5,575,601 and $4,510,903 for the
years ended December 31, 1998 and 1997, respectively.

         VALIC received surrender charges of $4,581,641 and $2,769,370 for the
years ended December 31, 1998 and 1997, respectively. In addition, VALIC
received $53,171 and $6,156 for the year ended December 31, 1998, in sales load
on variable annuity purchase payments for Divisions 10A and 10B, respectively.
VALIC received $63,727 and $7,426 for the year ended December 31, 1997, in
sales load on variable annuity purchase payments for Divisions 10A and 10B,
respectively.

         VALIC contributed to the Separate Account, $100,000 and $74,900,000 on
August 26, 1998 and September 1, 1998, respectively, in order to provide
initial funding for the AGSPC 3 mutual funds. Capital surplus amounts reflected
in the Statements of Net Assets for Divisions 33 through 44, 48 through 50 and
58 through 60 are not subject to contract holder charges since they do not
represent reserves for annuity contracts issued. 

NOTE D -- INVESTMENTS

NOTE G -- YEAR 2000 (UNAUDITED)

         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.

         In addition, the Separate Account 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, as
well as contingency plans for any identified risks or shortcomings, 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 December 31, 1998, VALIC has incurred and expensed $26.7
million (pretax) related to Year 2000 readiness, including $20.2 million
incurred in 1998.

         As of December 31, 1998, VALIC has completed the inventory,
assessment, testing, reprogramming and implementation phases of the plan with
respect to its critical systems. VALIC believes its comprehensive plan and
resource commitment will allow it to meet its Year 2000 objectives. However,
the Year 2000 issue remains complex and the risks, uncertainties, and
unforeseen circumstances associated with the Year 2000 issue could have a
material adverse impact on VALIC and the Separate Account.

================================================================================


TO THE BOARD OF THE VARIABLE ANNUITY LIFE INSURANCE COMPANY AND CONTRACT OWNERS
OF THE VARIABLE ANNUITY LIFE INSURANCE COMPANY SEPARATE ACCOUNT A

We have audited the accompanying statements of net assets of The Variable
Annuity Life Insurance Company Separate Account A ("the Separate Account") and
each of the divisions (1, 2, 4, 5, 6, 7, 8, 10A, 10B, 10C, 10D, 11 through 44
inclusive, 48 through 51 inclusive, and 58 through 60, inclusive) comprising
the Separate Account as of December 31, 1998. We have also audited the related
statements of operations for the year then ended and the statements of changes
in net assets for each of the two years in the period then ended of the
Separate Account and each of its divisions except for divisions 33 through 44
inclusive, divisions 48 through 50 inclusive, and divisions 58 through 60,
inclusive, for which we have audited the statements of operations and changes
in net assets for the period from August 26, 1998 (inception) to December 31,
1998, and for division 51 for which we have audited the statements of
operations and changes in net assets for the period from September 22, 1998
(inception) through December 31, 1998. These financial statements are the
responsibility of the Separate Account's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits 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 statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of December 31, 1998,
by correspondence with the transfer agents. 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 audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Separate Account and each
of the divisions comprising the Separate Account at December 31, 1998, and the
results of their operations and changes in their net assets for each of the
periods identified above, in conformity with generally accepted accounting
principles.

ITEM 28. INDEMNIFICATION
 
     Set forth below is a summary of the general effect of applicable provisions
of the Depositor's Bylaws regarding indemnification of, and advancement of legal
expenses to, the Depositor's officers, directors and employees (collectively,
"Indemnitees").
 
     The Depositor shall indemnify any Indemnitee who was or is a named
defendant or respondent or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative, arbitrative, or investigative (including any action by or in the
right of the Depositor), or any appeal of such action, suit or proceeding and
any inquiry or investigation that could lead to such an action, suit or
proceeding, by reason of the fact that the Indemnitee is or was a director, or
officer or employee of the Depositor, or is or was serving at the request of the
Depositor as a director, officer, partner, venturer, proprietor, trustee,
employee, or similar functionary of another foreign or domestic corporation or
nonprofit corporation, partnership, joint venture, sole proprietorship, trust,
employee benefit plan or other enterprise, against judgments, penalties
(including excise and similar taxes), fines, amounts paid in settlement, and
reasonable expenses (including court costs and attorneys' fees) actually
incurred by him in connection with such action, suit or proceeding, if
Indemnitee acted in good faith and in a manner he reasonably believed, (i) in
the case of conduct in his official capacity as a director of the Depositor, to
be in the best interests of the Depositor and (ii) in all other cases, to be not
opposed to the best interests of the Depositor; and, with respect to any
criminal action or proceeding, if Indemnitee had no reasonable cause to believe
his conduct was unlawful; provided, however that in the case of any threatened,
pending or completed action, suit or proceeding by or in the right of the
Depositor, the indemnity shall be limited to reasonable expenses (including
court costs and attorneys' fees) actually incurred in connection with such
action, suit or proceeding; and no indemnification shall be made in respect of
any claim, issue or matter as to which such person shall have been adjudged to
be liable to the Depositor or liable on the basis that personal benefit was
improperly received by him, whether or not the benefit resulted from an action
taken in the person's official capacity as a director or officer. The
termination of any action, suit or proceeding by judgment, order, settlement, or
conviction, or on a plea of nolo contendere or its equivalent shall not, of
itself, create a presumption that the Indemnitee did not act in good faith and
in a manner which Indemnitee reasonably
 
                                       C-8
<PAGE>   876
 
believed to be in the best interests of the Depositor; and, with respect to any
criminal action or proceeding, shall not create a presumption that the person
had reasonable cause to believe that his conduct was unlawful.
 
     Where an Indemnitee of the Depositor or other person entitled to indemnity
hereunder has been wholly successful, on the merits or otherwise, in defense of
any such action, suit or proceeding, Indemnitee shall be indemnified against
reasonable expenses (including court costs and attorneys' fees) actually
incurred by him in connection therewith.
 
     Any indemnification (unless otherwise ordered by a court of competent
jurisdiction) shall be made by the Depositor only as authorized in a specific
case upon a determination that the applicable standard of conduct has been met.
Such determination shall be made (i) by the Board of Directors by a majority
vote of a quorum consisting of directors who at the time of the vote have not
been named as defendants or respondents in such action, suit or proceeding, or
(ii) if such a quorum cannot be obtained, by a majority vote of a committee of
the Board of Directors, designated to act in the matter by a majority vote of
all directors, consisting solely of two or more directors who at the time of the
vote are not named defendants or respondents in such action, suit or proceeding,
or (iii) by special legal counsel selected by the Board of Directors (or a
committee thereof) by vote in the manner set forth in subparagraphs (i) and (ii)
immediately above or if such a quorum cannot be obtained and such a committee
cannot be established, by a majority vote of all directors, or (iv) by the
shareholders in a vote that excludes the shares held by any Indemnitee who is
named as a defendant or respondent in such action, suit or proceeding.
 
     Reasonable expenses incurred by an Indemnitee of the Depositor or other
person entitled to indemnity hereunder, who was, is or is threatened to be made
a named defendant or respondent in any such action, suit or proceeding described
above may be paid by the Depositor in advance of the final disposition thereof
upon (i) receipt of a written affirmation by the Indemnitee of his good faith
belief that he has met the standard of conduct necessary for indemnification
under this article and a written undertaking by or on behalf of the Indemnitee
to repay such amount unless it shall ultimately be determined that he is
entitled to be indemnified by the Depositor as authorized under this article and
(ii) a determination that the facts then known to those making the determination
would not preclude indemnification under this article.
 
     Notwithstanding any other provision of this article, the Depositor may pay
or reimburse expenses incurred by any Indemnitee of the Depositor or any other
person entitled to indemnity hereunder in connection with his appearance as a
witness or other participation in any action, suit or a proceeding described
above at a time when he is not named defendant or respondent in such action,
suit or proceeding.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers and controlling
persons of the Registrant, as provided above or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification by the Depositor is against public policy, as expressed in the
Act, and therefore may be unenforceable. In the event (a) that a claim for such
indemnification (except insofar as it provides for the payment by the Depositor
of expenses incurred or paid by a director, officer or controlling person in the
successful defense of any action, suit or proceeding) is asserted against the
Depositor by such director, officer or controlling person; and (b) the
Securities and Exchange Commission is still of the same opinion that the
Depositor or Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit such cause to a court of
appropriate jurisdiction, the question of whether such indemnification by the
Depositor is against public policy as expressed in the Act will be governed by
the final adjudication of such issue.

Participants, Annuitants or Beneficiaries in addition to the charges described
in the prospectuses for the Contract.

     The books or other documents required to be maintained by Section 31(a) of
the Investment Company Act of 1940 and the Rules promulgated thereunder will be

        2929 Allen Parkway
        Houston, Texas 77019
 
ITEM 31. MANAGEMENT SERVICES
 
     There have been no management-related services provided to the Separate

following undertakings:
 
          1. To file a post-effective amendment to this registration statement
     as frequently as necessary to ensure that the audited financial statements
     in the registration statement are never more than 16 months old for so long

<PAGE>   880
 
     b. The Company hereby represents that the fees and charges deducted under
the contract, in the aggregate, are reasonable in relation to the services
rendered, the expenses expected to be incurred and the risks assumed by the
Company.
 
ITEM 33. WITHDRAWAL RESTRICTIONS FOR 403(B) PLANS
 
     The Tax Reform Act of 1986 added to the Internal Revenue Code a new Section
403(b)(11) which applies to tax years beginning after December 31, 1988. This
paragraph provides that withdrawal restrictions apply to contributions made and
interest earned subsequent to December 31, 1988. Such restrictions require that
distributions not begin before age 59 1/2, separation from service, death,
disability, or hardship (only employee contributions without accrued interest
may be withdrawn in case of hardship). These withdrawal restrictions appear in
the Section "Federal Tax Matters" in either the Prospectus or the Statement of
Additional Information for Contracts of this Registration Statement.
 
     The Company relies on a no-action letter issued by the Securities and
Exchange Commission on November 28, 1988 stating that no enforcement action
would be taken under sections 22(e), 27(c)(1), or 27(d) of the Investment
Company Act of 1940 (the "Act") if, in effect, the Company permits restrictions
on cash distributions from elective contributions to the extent necessary to
comply with Section 403(b)(11) of the Internal Revenue Code in accordance with
the following conditions:
 
          (1) Include appropriate disclosure regarding the redemption
     restrictions imposed by Section 403(b)(11) in each registration statement,
     including the prospectus, used in connection with the offer of the
     Contract;
 
          (2) Include appropriate disclosure regarding the redemption
     restrictions imposed by Section 403(b)(11) in any sales literature used in
     connection with the offer of the Contract;
 
          (3) Instruct sales representatives who solicit participants to
     purchase the Contract specifically to being the redemption restrictions
     imposed by Section 403(b)(11) to the attention of the potential
     participants;
 
          (4) Obtain from each plan participant who purchases a Section 403(b)
     annuity Contract, prior to or at the time of such purchase, a signed
     statement acknowledging the participant's understanding of (1) the
     restrictions on redemption imposed by Section 403(b)(11), and (2) the
     investment alternatives available under the employer's Section 403(b)
     arrangement, to which the participant may elect to transfer his contract
     value.
 
     The Company has complied, and is complying, with the provisions of
paragraphs (1)-(4) above.
 
     The Company relies on Rule 6c-7 of the Act which states that a registered
separate account, and any depositor of or underwriter for such account, shall be
exempt from the provisions of sections 22(e), 27(c)(1) and 27(d) of the Act with
respect to this Contract participating in this account to the extent necessary
to permit compliance with the Texas Optional Retirement Program (Program) in
accordance with the following conditions:
 
          (a) include appropriate disclosure regarding the restrictions on
     redemption imposed by the Program in each registration statement, including
     the prospectus, used in connection with the Program;
 
          (b) include appropriate disclosure regarding the restrictions on
     redemption imposed by the Program in any sales literature used in
     connection with the offer of this Contract to Program participants;
 
          (c) instruct salespeople who solicit Program participants to purchase
     this Contract specifically to bring the restrictions on redemption imposed
     by the Program to the attention of potential Program participants;
 
          (d) obtain from each Program participant who purchases this Contract
     in connection with the Program, prior to or at the time of such purchase, a
     signed statement acknowledging the restrictions on redemption imposed by
     the Program.
 
                                      C-13
<PAGE>   881
 
     The Company has complied, and is complying, with the provisions of
paragraphs (a)-(d) above.
 
     The Company relies on an order issued by the Securities and Exchange
Commission on May 19, 1993 exempting it from the provisions of section 22(e),
27(c)(1) and 27(d) of the Act with respect to this Contract participating in
this account to the extent necessary to permit compliance with the Optional
Retirement Program of the State University System of Florida ("Florida ORP") as
administered by the Division of Retirement of the Florida Department of
Management Services ("Division") in accordance with the following conditions:
 
          (a) include appropriate disclosure regarding the restrictions on
     redemption imposed by the Division in each registration statement,
     including the prospectus, relating to the Contracts issued in connection
     with the Florida ORP;
 
          (b) include appropriate disclosure regarding the restrictions on
     redemption imposed by the Division in any sales literature used in
     connection with the offer of Contracts to Eligible Employees;
 
          (c) instruct salespeople who solicit Eligible Employees to purchase
     the Contracts specifically to bring the restrictions on redemption imposed
     by the Division to the attention of the Eligible Employees;
 
          (d) obtain from each Participant in the Florida ORP who purchases a
     Contract, prior to or at the time of such purchase, a signed statement
     acknowledging the Participant's understanding: (i) of the restrictions on
     redemption imposed by the Division, and (ii) that other investment
     alternatives are available under the Florida ORP, to which the Participant
     may elect to transfer his or her Contract values.
 
     The Company has complied, and is complying, with the provisions of
paragraphs (a)-(d) above.

Not withstanding any language in the Contract to the contrary, the Contract is
amended as follows:

Annuity Rate Tables.  The value We use to determine annuity payments will be the
applied portion of the Accumulation Value on the tenth day (or the preceding
business day if the tenth day is not a business day) preceding the date of the
first annuity payment, less any applicable premium taxes. The following tables
are based on the Annuity 2000 mortality table and assume births before the year
1936. The tables show the amount required to purchase a first monthly payment of
$1.00. Quarterly, semiannual, and annual payments may also be selected. The
amount of each payment will depend upon the Annuitant's adjusted age at the
time the first payment is due. Adjusted age will be determined in accordance
with the following:

Beneficiaries.

       a.      Unlocatable Beneficiaries. If We cannot obtain a mailing address 
               for the designated beneficiary using methods allowed by and
               within the period required by applicable state or federal
               regulations, then We will deem the contract holder to have no
               designated beneficiary and We will pay the proceeds accordingly.
               If no applicable law provides guidelines and We cannot obtain a
               mailing address for the designated beneficiary by reasonable
               means and within a reasonable period, then We will deem the
               contract holder to have no designated beneficiary and We will pay
               the proceeds accordingly.

       b.      Trust or Estate as Beneficiary. Payments to a Beneficiary that 
               is a trust or an estate will be made in a lump sum or in
               installments over a period not to exceed five years, to the
               extent required by applicable law.

Investment Options. We reserve the right to limit allocations among Investment 
Options.

Separate Account Charge. The amount of the Separate Account Charge depends on 
the Variable Investment Option from which it is deducted, and is imposed at an 
annual rate of up to 1.25% of the assets of the Variable Investment Option.

The effective date of this Endorsement is the Policy Issue Date.

Not withstanding any language in the Contract to the contrary, the Contract is
amended as follows:

Annuity Rate Tables.  The value We use to determine annuity payments will be the
applied portion of the Accumulation Value on the tenth day (or the preceding
business day if the tenth day is not a business day) preceding the date of the
first annuity payment, less any applicable premium taxes. The following tables
are based on the Annuity 2000 mortality table and assume births before the year
1936. The tables show the amount required to purchase a first monthly payment of
$1.00. Quarterly, semiannual, and annual payments may also be selected. The
amount of each payment will depend upon the Annuitant's adjusted age at the time
the first payment is due. Adjusted age will be determined in accordance with the
following:

Beneficiaries.

       a.      Unlocatable Beneficiaries. If We cannot obtain a mailing address 
               for the designated beneficiary using methods allowed by and
               within the period required by applicable state or federal
               regulations, then We will deem the contract holder to have no
               designated beneficiary and We will pay the proceeds accordingly.
               If no applicable law provides guidelines and We cannot obtain a
               mailing address for the designated beneficiary by reasonable
               means and within a reasonable period, then We will deem the
               contract holder to have no designated beneficiary and We will pay
               the proceeds accordingly.

       b.      Trust or Estate as Beneficiary. Payments to a Beneficiary that 
               is a trust or an estate will be made in a lump sum or in
               installments over a period not to exceed five years, to the
               extent required by applicable law.

Investment Options. We reserve the right to limit allocations among Investment 
Options.

the Variable Investment Option from which it is deducted, and is imposed at an 
annual rate of up to 1.25% of the assets of the Variable Investment Option.

Not withstanding any language in the Contract to the contrary, the Contract is
amended as follows:

Annuity Rate Tables.  The value We use to determine annuity payments will be the
applied portion of the Accumulation Value on the tenth day (or the preceding
business day if the tenth day is not a business day) preceding the date of the
first annuity payment, less any applicable premium taxes. The following tables
are based on the Annuity 2000 mortality table and assume births before the year
1936. The tables show the amount required to purchase a first monthly payment of
$1.00. Quarterly, semiannual, and annual payments may also be selected. The
amount of each payment will depend upon the Annuitant's adjusted age at the time
the first payment is due. Adjusted age will be determined in accordance with the
following:

Beneficiaries.

       a.      Unlocatable Beneficiaries. If We cannot obtain a mailing address 
               for the designated beneficiary using methods allowed by and
               within the period required by applicable state or federal
               regulations, then We will deem the contract holder to have no
               designated beneficiary and We will pay the proceeds accordingly.
               If no applicable law provides guidelines and We cannot obtain a
               mailing address for the designated beneficiary by reasonable
               means and within a reasonable period, then We will deem the
               contract holder to have no designated beneficiary and We will pay
               the proceeds accordingly.

       b.      Trust or Estate as Beneficiary. Payments to a Beneficiary that 
               is a trust or an estate will be made in a lump sum or in
               installments over a period not to exceed five years, to the
               extent required by applicable law.

Death of the Owner. If You are not the Annuitant and die during the 
Accumulation Period, the Contract values must be distributed in the same manner 
and time as the Contract would require for the Annuitant's death, except that 
those Contract provisions shall be applied to You instead of the Annuitant. In 
that case, payments will be made to the Contingent Owner, if any, or to the 
Beneficiary if there is no Contingent Owner who survives You. Unless You are

                             PARTICIPATION AGREEMENT

   
         THIS AGREEMENT is made by and between, Evergreen Equity Trust, a
Delaware trust, and such other funds or portfolios of series-type mutual funds
set forth on Schedule A attached hereto as amended from time to time, ("FUND") 
and The Variable Annuity Life Insurance Company ("VALIC"), a life insurance 
company organized under the laws of the State of Texas, on its own behalf and 
on behalf of each segregated asset account set forth on Schedule B hereto as 
amended from time to time (each such account hereinafter referred to 
as "ACCOUNT").
    

         WHEREAS, FUND is registered with the Securities and Exchange
Commission ("SEC") under the Investment Company Act of 1940 (the "1940 Act") as
an open-end, diversified, management investment company; and

         WHEREAS, FUND shares are issued to the general public and to the
separate accounts of insurance companies ("Participating Insurance Companies")
to fund variable insurance products and certain qualified pension and
retirement plans; and

   
    


<PAGE>   2


   
         WHEREAS, VALIC has established ACCOUNT to offer variable contracts (the
"Contracts") which VALIC has registered under the Securities Act of 1933, as
amended (the "1933 Act"), and is desirous of having FUND as one of the
underlying funding vehicles for the Contracts; and
    

         WHEREAS, FUND knows of no reason why FUND shares may not be sold 
to Participating Insurance Companies to fund variable insurance products
and qualified pension and retirement plans; and

         WHEREAS, VALIC intends to purchase shares of other open-end,
management investment companies that offer shares to the general public to fund
the Contracts; and

         WHEREAS, to the extent permitted by applicable insurance laws and
regulations, VALIC intends to purchase shares of FUND to fund the Contracts and
FUND is or will be authorized to sell such shares to VALIC at net asset value;

         WHEREAS, VALIC and affiliates of VALIC will provide subcustodian,
record keeping, account maintenance and/or other administrative services for
Contract owners and participants, employee benefit plans and participants, and
other investors;

   
         NOW, THEREFORE, in consideration of their mutual promises, VALIC and 
FUND agree as follows:
    

                                      -2-

<PAGE>   3


   
         1. FUND agrees to make FUND shares available for purchase by VALIC and
ACCOUNT at the applicable net asset value per share on those days on which FUND
calculates its net asset value pursuant to SEC rules. FUND shall use reasonable
efforts to calculate such net asset value on each day which the New York Stock
Exchange is open for trading. Notwithstanding the foregoing, the FUND may refuse
to sell shares to any person, or suspend or terminate the offering of shares, if
such action is required by law or by regulatory authorities having jurisdiction
or is, in the sole discretion of the FUND acting in good faith and in light of
their fiduciary duties under federal and any applicable state laws, necessary in
the best interests of the shareholders of the FUND.
    

         2. Issuance and transfer of FUND's shares will be by book entry only.
Stock certificates will not be issued to VALIC or ACCOUNT. Shares ordered from
FUND will be recorded in an appropriate title for ACCOUNT or the appropriate
subaccount of ACCOUNT.

         3. FUND shall furnish same day notice (by wire, telecopier, or
telephone followed by written confirmation) to VALIC of any income, dividends
or capital gain distributions payable on FUND's shares. VALIC hereby elects to
receive all such income, dividends and capital gain distributions of a FUND in
the form of additional shares of that FUND. VALIC reserves the right to revoke
this election and to receive all such income, dividends and capital gain
distributions in cash. FUND shall notify VALIC of the number of shares so
issued as payment of such dividends and distributions.

                                      -3-

<PAGE>   4


   
         4. (a) FUND agrees to sell to VALIC shares of the FUND which VALIC
orders, executing such orders on a daily basis at the net asset value next
computed after receipt by FUND or its designee in proper form of the order for
the shares of FUND. For purposes of this Section 4(a), VALIC shall be the
designee of FUND for receipt of such orders from VALIC and receipt by such
designee shall constitute receipt by FUND; provided that FUND receives notice
of such order by 9:00 a.m. Eastern time on the next following Business Day.
"Business Day" shall mean any day on which the New York Stock Exchange is open
for trading and on which FUND calculates its net asset value pursuant to the
rules of the SEC. "Proper form" means that amounts to be invested or redeemed
are identified on VALIC's computer system by Participant, Contract and Fund in
accordance with VALIC's standard procedures for processing transactions. (which 
comply with procedures and form in Fund's prospectus).
    

   
         (b) FUND agrees to redeem for cash (or in kind to the limited extent
disclosed in the Fund's prospectus), on VALIC's request, any full or fractional
shares of FUND held by VALIC, executing such requests on a daily basis at the
net asset value next computed after receipt by FUND or its designee of the
request for redemption in proper form. Fund shall not bear any responsibility
whatsoever for the proper disbursement to Contract Participants or crediting
redemption proceeds to Contract Participants; VALIC alone shall be responsible
for such actions. For purposes of this Section 4(b), VALIC shall be the designee
of FUND for receipt of requests for redemption from VALIC and receipt by such
designee shall constitute receipt by FUND; provided that FUND receives notice of
such request for redemption by 9:00 a.m. Eastern time on the next following
Business Day.
    

                                      -4-

<PAGE>   5


   
            (c) FUND shall make the net asset value per share available to VALIC
on a daily basis as soon as reasonably practical after the net asset value per
share is calculated but shall use its best efforts to make such net asset value
available by 6:30 p.m. Eastern time. If FUND provides VALIC with the incorrect
share net asset value information through no fault of VALIC, VALIC on behalf of
the Separate Accounts, shall be entitled to an adjustment to the number of
shares purchased or redeemed to reflect the correct share net asset value. Any
error in the calculation of net asset value, dividend and capital gain
information greater than the materiality standard set by the SEC shall be
reported to VALIC immediately upon discovery.
    

   
            (d) If VALIC requests the purchase of FUND shares, VALIC shall pay
for such purchase by wiring federal funds to FUND or its designated custodial
account on the day the order is transmitted by VALIC. If VALIC requests a net
redemption resulting in a payment of redemption proceeds to VALIC (VALIC shall
use its best efforts to pre-notify the Fund of any large trades), FUND shall
wire the redemption proceeds to VALIC on the day the order is transmitted by
VALIC, unless doing so would require FUND to dispose of portfolio securities or
otherwise incur additional costs, but in such event, proceeds shall be wired to
VALIC within three business days and FUND shall notify the person designated in
writing by VALIC as the recipient for such notice of such delay by 3:00 p.m.
Eastern time the same Business Day that VALIC transmits the redemption order to
FUND. If VALIC's order requests the application of redemption proceeds from the
redemption of shares of one FUND to the purchase of shares of another FUND, FUND
shall so apply such proceeds the same Business Day that VALIC transmits such
order to FUND.

         5. (a) FUND shall provide VALIC with as many copies of FUND's current
prospectus as VALIC may reasonably request. If requested by VALIC in lieu
thereof, FUND shall provide such documentation (including a copy of the new
prospectus in computer form) and other assistance as is reasonably necessary in
order for VALIC once each year (or more frequently if the prospectus for FUND is
amended) to have the prospectuses for the Contracts and for the FUND printed
together in one document. FUND shall provide VALIC with as many copies of any
prospectus supplement as VALIC may reasonably request.

costs. VALIC will provide FUND on a semi-annual basis, or more frequently as
reasonably requested by FUND, with a current tabulation of the number of

                      connection with the sale of the Contracts or FUND shares;
                      or 

                (ii)  arise out of or as a result of statements or
                      representations (other than statements or representations
                      contained in the registration statement, prospectus or
                      sales literature of FUND not supplied by VALIC, or

                      or persons under its control, with respect to the sale or
                      distribution of the Contracts or FUND shares; or

                      statement of a material fact contained in a registration
                      statement, prospectus, or sales literature of FUND, or
                      any amendment thereof or supplement thereto, or the
                      omission or alleged omission to state therein a material
                      fact required to be stated therein or necessary to make
                      the statements therein not misleading if such statement
                      or omission or such alleged statement or omission was
                      made in reliance upon and in conformity with information
                      furnished to FUND by or on behalf of VALIC; or

   
                (iv)  arise as a result of (i) a failure by VALIC to
                      substantially provide the services and furnish the
                      materials under the terms of this Agreement; or (2) a
                      failure by VALIC to register the Contracts under the
                      1933 Act;
    

   
                (v)   arise out of or result from any material breach of any
                      representation, warranty or agreement made by VALIC in
                      this Agreement or arise out of or result from any other
                      material breach of this Agreement by VALIC; or
    

   
                (vi)  arise out of or result from the fact that the Contracts
                      are invested in shares of regulated investment companies
                      that are also available without limitation to investors
                      from the general public; or
    

   
                (vii) arise out of or result from negligence or wrongful conduct
                      in VALIC's administration of the ACCOUNTS or the
                      Contracts.  
    


            (b) VALIC shall not be liable under this indemnification provision
with respect to any losses, claims, damages, liabilities or litigation to which
an Indemnified Party is subject by reason of such Indemnified Party's willful
misfeasance, bad faith, or gross negligence in the performance of such
Indemnified Party's duties or by reason of such Indemnified Party's reckless
disregard of obligations or duties under this Agreement or to FUND.

<PAGE>   14


            (c) VALIC shall not be liable under this indemnification provision
with respect to any claim made against an Indemnified Party unless such
Indemnified Party shall have notified VALIC in writing within a reasonable time
after the summons or other first legal process giving information of the nature
of the claim shall have been served upon such Indemnified Party (or after such
Indemnified Party shall have received notice of such service on any designated
agent), but failure to notify VALIC of any such claim shall not relieve VALIC
from any liability for indemnification which it may have to the Indemnified
Party against whom such action is brought other than that liability which may
have been incurred solely as a result of the failure to give notice. In case
any such action is brought against an Indemnified Party, VALIC shall be
entitled to assume the defense thereof, with counsel satisfactory to the party
named in the action. After notice from VALIC to such party of VALIC's election
to assume the defense thereof, the Indemnified Party shall bear the fees and
expenses of any additional counsel retained by it, and VALIC will not be liable
to such party under this Agreement for any legal or other expenses subsequently
incurred by such party independently in connection with the defense thereof
other than reasonable costs of investigation.

   
         9. (a) Except as limited by and in accordance with the provisions of

directors and officers and each person, if any, who controls VALIC within the
meaning of Section 15 of the 1933 Act (collectively, the "Indemnified Parties"
for purposes of this Section 9) against any and all losses, claims, damages,
liabilities (including amounts paid in settlement with the written consent of
FUND) or litigation (including legal and other expenses) to which the
Indemnified Parties may become subject under any statute, regulation, at common
law or otherwise, insofar as such losses, claims, damages, liabilities or
expenses (or actions in respect thereof) or settlements are related to the sale
or acquisition of FUND's shares or the Contracts and:
    

   
                (i)   arise out of or are based upon any untrue statement or
                      alleged untrue statement of any material fact contained in
                      the registration statement or prospectus or sales
                      literature of FUND (or any amendment or supplement to any
                      of the foregoing), or arise out of or are based upon the
                      omission or the alleged omission to state therein a
                      material fact required to be stated therein or necessary
                      to make the statements therein not misleading, provided
                      that this agreement to indemnify shall not apply as to any
                      Indemnified Party if such statement or omission or such
                      alleged statement or omission was made in reliance upon
                      and in conformity with information furnished to FUND or
                      its adviser by or on behalf of VALIC for use in the
                      registration statement or prospectus for FUND or in sales
                      literature (or any amendment or supplement) or otherwise
                      for use in connection with the sale of the Contracts or
                      FUND shares; or

                (ii)  arise out of or as a result of statements or
                      representations (other than statements or representations
                      contained in the registration statement, prospectus or
                      sales literature for the Contracts not supplied by FUND or
                      its adviser or persons under their control) or wrongful
                      conduct of FUND or persons under their control, with
                      respect to the sale or distribution of the Contracts or
                      FUND shares; or
    

                (iii) arise out of any untrue statement or alleged untrue
                      statement of a material fact contained in a registration
                      statement, prospectus, or sales literature covering the
                      Contracts, or any amendment thereof or supplement
                      thereto, or the omission or alleged omission to state
                      therein a material fact required to be stated therein or
                      necessary to make the statements therein not misleading,
                      if such statement or omission or such alleged statement
                      or omission was made in reliance upon and in conformity
                      with information furnished to VALIC by or on behalf of
                      FUND; or

                (iv)  arise as a result of (1) a failure by FUND to
                      substantially provide the services and furnish the
                      materials under the terms of this Agreement; (2) a
                      failure by FUND to qualify as a 


                                     -16-
<PAGE>   17


                      Regulated Investment Company under Subchapter M of the
                      Code; or (3) a failure by FUND to register its shares but
                      only if such registration is required in those states
                      where the FUND is subject to the state securities
                      commission. 

                (v)   arise out of or result from any material breach of any
                      representation and/or warranty made by FUND in this
                      Agreement or arise out of or result from any other
                      material breach of this Agreement by FUND.

   
                (vi)  arise out of or result from negligence or wrongful 
                      conduct in FUND's administration of FUND Shares.
    

   
            (b) FUND shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or
litigation to which an Indemnified Party is subject by reason of such
Indemnified Party's willful misfeasance, bad faith, or gross negligence in the
performance of such Indemnified Party's duties or by reason of such Indemnified
Party's reckless disregard of obligations and duties under this Agreement or to
VALIC.
    

   
            (c) FUND shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified FUND in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice
of such service on any designated agent), but failure to notify FUND of any
such claim shall not relieve 
    


                                     -17-

FUND from any liability for indemnification which it may have to the Indemnified
Party against whom such action is brought other than that liability which may
have been incurred solely as a result of the failure to give notice. In case any
such action is brought against the Indemnified Parties, FUND shall be entitled
to participate at its own expense in the defense thereof. FUND also shall be
entitled to assume the defense thereof, with counsel satisfactory to the party
named in the action. After notice from FUND to such party of FUND's election to
assume the defense thereof, the Indemnified Party shall bear the fees and
expenses of any additional counsel retained by it, and FUND will not be liable
to such party under this Agreement for any legal or other expenses subsequently
incurred by such party independently in connection with the defense thereof
other than reasonable costs of investigation.
    

   
             (d) VALIC agrees to notify FUND promptly of the commencement of 
any litigation or proceedings that impact the FUND, against VALIC or any of its 
officers or directors in connection with the issuance or sale of the Contracts, 
the operation of the ACCOUNTS or the sale or acquisition of shares of the FUND. 
    

   
         10. FUND represents and warrants that FUND shares sold pursuant to this
Agreement shall be registered under the 1933 Act and duly authorized for
issuance, and shall be issued, in compliance in all material respects with
applicable law, and that FUND is and shall remain registered under the 1940 Act
for so long as required thereunder. FUND further represents and warrants that
FUND qualifies as a Regulated Investment Company under Subchapter M of the Code,
and will make every effort to maintain such qualification (under Subchapter M or
any successor or similar provisions), and that FUND will notify VALIC
immediately upon having a reasonable basis for believing that it has ceased to
so qualify or that it might not so qualify in the future. FUND will register and
qualify its shares for sale in accordance with the laws of the various states as
may be required by law in those states where this FUND is subject to the
jurisdiction of the state securities commission. FUND makes no representations
or warranties as to whether any aspect of its operations (including, but not
limited to, fees, expenses and investment policies) complies or will comply with
the insurance laws or insurance regulations of the various states. FUND further
represents and warrants that all of its directors, officers, employees,
investment advisers, and other individuals/entities dealing with the money or
securities of the FUND are and shall continue to be at all times covered by a
blanket fidelity bond or similar coverage for the benefit of the FUND in an
amount not less than the minimal coverage as required by Rule 17g-1 under the
1940 Act or related provisions as may be promulgated from time to time. The
aforesaid Bond shall include coverage for larceny and embezzlement and shall be
issued by a reputable bonding company.

<PAGE>   19


   
         11. VALIC represents and warrants that it is an insurance company duly
organized and in good standing under applicable law and that it has legally and
validly established ACCOUNT as a segregated asset account under Texas law and
has registered ACCOUNT as a unit investment trust under the 1940 Act. VALIC
represents and warrants that the Contracts are or will be registered under the
1933 Act and that the Contracts will be issued and sold in compliance in all
material respects with all applicable federal and state laws and that the sale
of the Contracts shall apply in all material aspects with state insurance
suitability requirements were applicable. VALIC will notify FUND immediately
upon having a reasonable basis for believing that the ACCOUNT or Contracts have
ceased to qualify as segregated accounts or variable annuity contracts for
relevant diversification purposes. VALIC represents and warrants that all of its
officers, employees, investment advisers, and other individuals or entities
described in Rule 17g-1 under the 1940 Act, that deal with the money and/or
securities of the FUND, are and shall continue to be at all times covered by a
blanket fidelity bond or similar coverage for the benefit of FUND, in the amount
not less than the Rule requires. The aforesaid bond shall include coverage for
larceny and embezzlement and shall be issued by a reputable bonding company.
    

   
         12. FUND will provide VALIC with at least one complete copy of all
prospectuses, statements of additional information, annual and semi-annual
reports, proxy statements, exemptive applications which disclose the
relationship of the FUND and VALIC or which may have an effect upon the FUND's
relationship with VALIC, and all amendments or supplements to any of the above
that relate to the FUND promptly after the filing of each such document with the
SEC or other regulatory authority. VALIC will provide FUND or its designee with
at least one complete copy of all prospectuses, statements of additional
information, annual and semi-annual reports, solicitation for voting
instructions, proxy statements, prices of sales literature and other promotional
material, exemptive applications, requests for no-action relief, and all
amendments or supplements to any of the above in which Fund or its advisers are
named, that relate to ACCOUNT or Contracts, contemporaneously with the filing of
each document with the SEC, NASD or other regulatory authority.

         13. Each party hereto shall cooperate with each other party and all
appropriate governmental authorities having jurisdiction (including, without
limitation, the SEC, the NASD, and state insurance regulators) and shall permit
such authorities reasonable access to its books and records in connection with
any investigation or inquiry relating to this Agreement or the transactions
contemplated hereby.

   
         14. VALIC will provide pass-through voting privileges to all Contract
owners so long as the Commission continues to interpret the 1940 Act as
requiring pass-through voting privileges for variable contract owners.
Accordingly, VALIC will solicit voting instructions from Contract Participants
and vote shares of FUND held in ACCOUNT in a manner consistent with voting
instructions timely-received from Contract owners. VALIC will vote shares of
FUND held in ACCOUNT for which no voting instructions from Contract owners are
timely-received, as well as shares of FUND which VALIC itself owns, in the same
proportion as those shares of FUND for which voting instructions from Contract
owners are timely-received. Participating Insurance Companies will be
responsible for assuring that each of their separate accounts participating in
FUND calculates voting privileges in a manner consistent with other
Participating Insurance Companies.
    

   
         15. FUND agrees to comply with any applicable state insurance laws or
regulations, including cooperating with VALIC in any filings of sales literature
for the Contracts, to the extent notified thereof in writing by VALIC, unless
such compliance is deemed by FUND to be unduly burdensome, in which event any
Party may exercise its option to terminate this Agreement under Section 16
hereof, except that such termination shall be effective immediately.

            (c) This Agreement shall terminate without penalty at the option of
the terminating party in accordance with the following provisions:

                (i)   At the option of VALIC or FUND at any time from the date
                      hereof upon 90 days' advance written notice, unless a
                      shorter time is agreed to by the parties;

   
                (ii)  At the option of VALIC if FUND shares are not reasonably
                      available to meet the requirements of the Contracts,
                      provided however, that such a termination shall apply only
                      to the series of FUND not reasonably available and FUND
                      shall have thirty (30) days from initial notification by
                      VALIC of the deficiency to correct such deficiency.
                      Thereafter, prompt written notice of the election to

                (iii) At the option of VALIC, upon the institution of formal
                      proceedings against FUND by the SEC, the NASD, or any
                      other regulatory body, the expected or anticipated ruling,
                      judgment or outcome of which would, in VALIC'S reasonable
                      judgment exercised in good faith, materially impair FUND'S
                      ability to meet and perform FUND'S obligations and duties
                      hereunder. Prompt notice of election to terminate under

                      proceedings against VALIC by the SEC, the NASD, or any
                      other regulatory body, the expected or anticipated
                      ruling, judgement or outcome which would, in FUND'S
                      reasonable judgment, materially impair VALIC'S ability to
                      meet and perform its obligations and duties hereunder.
                      Prompt notice of election to terminate under this
                      paragraph shall be furnished by FUND with said
                      termination to be effective upon receipt of notice;

                      sole judgment reasonably exercised in good faith, that
                      VALIC has suffered a material adverse change in its
                      business or financial condition or is the subject of
                      material adverse publicity and such material adverse
                      change or material adverse publicity is likely to have a
                      material adverse impact upon the operation or business
                      reputation of FUND, (2) FUND shall have notified VALIC in

                      this Agreement, and, (3) after consideration of the
                      actions taken by VALIC and any other changes in
                      circumstances since the giving of such notice, the
                      determination of FUND shall continue to apply on the
                      sixtieth (60th) day since giving of such notice, then such
                      sixtieth day shall be the effective date of termination;
    

   
                (vi)  At the option of VALIC after having been notified by FUND

                (vii) In the event FUND's shares are not registered, issued or
                      sold in accordance with applicable federal law, or such
                      law precludes the use of such shares of the FUND as the
                      underlying investment medium of the Contracts issued or
                      to be issued by VALIC. Prompt notice of election to

                (viii) At the option of FUND upon a reasonable determination by
                      the Board in good faith that it is no longer advisable
                      and in the best interests of shareholders for FUND to
                      continue to operate pursuant to this Agreement. Prompt

                      as annuity contracts or life insurance contracts, as
                      applicable, under the Code, or if FUND reasonably
                      believes that the Contracts may fail to so qualify.

                      material provision of this Agreement, which breach has
                      not been cured to the satisfaction of VALIC within ten

                (xiii) At the option of VALIC, if (1) VALIC shall determine, in
                      its sole judgment reasonably exercised in good faith,
                      that FUND is the subject of material adverse publicity
                      and such material adverse publicity is likely to have a
                      material adverse impact on the sale of the Contracts
                      and/or the operations or business reputation of VALIC,
                      (2) VALIC shall have notified FUND in writing of such
                      determination and its intent to terminate this Agreement,

                (xiv) At the option of VALIC, if VALIC shall determine that it
                      is no longer advisable and in the best interests of
                      Contract owners to utilize the FUND as underlying
                      investment vehicle and VALIC determines to substitute the
                      shares of another investment company for the
                      corresponding shares of FUND in accordance with the terms
                      of the Contracts for which those shares had been selected
                      to serve as the underlying investment media.

   
            (d) No termination of this Agreement shall be effective unless and
until the party terminating this Agreement gives prior written notice to all
other parties to this Agreement of its intent to terminate, which notice shall
set forth the basis for such termination.

             (e) Notwithstanding any termination of this Agreement pursuant to
Section 16(c) hereof, at the election of VALIC, FUND shall continue to make
available additional FUND shares, as provided below, pursuant to the terms and
conditions of this Agreement, for all Contracts in effect on the effective date
of termination of this Agreement (hereinafter referred to as "Existing
Contracts"). Specifically, without limitation, if VALIC elects to have FUND
make additional shares available, the owners of the Existing Contracts or
VALIC, whichever shall have legal authority to do so, shall be permitted to
reallocate investments in FUND, redeem investments in FUND and/or invest in
FUND upon the payment of additional premiums under the Existing Contracts. In
the event of a termination of this Agreement pursuant to Section 16(c) hereof,
VALIC, as promptly as is practicable under the circumstances, shall notify FUND
whether VALIC shall elect to continue to have FUND shares made available after
such termination. If FUND shares continue to be made available after such
termination, the provisions of this Agreement shall remain in effect and
thereafter either FUND or VALIC may terminate the Agreement, as so continued
pursuant to this Section 16(e), upon prior written notice to the other party
such notice to be for a period that is reasonable under the circumstances. In
determining whether to elect to continue to have additional FUND shares made
available, VALIC shall act in good faith, giving due consideration to the
interests of existing shareholders, including holders of Existing Contracts.
Notwithstanding the foregoing, FUND shall not be required to make available
additional FUND shares if doing so would be prohibited by law. VALIC and FUND 
agree that this Section 16(e) shall not apply to any termination under Sections 
8 or 9.

             (f) VALIC shall not redeem FUND shares attributable to Contract 
except (i) as necessary to implement Contract Participant initiated 
transactions, or (ii) as required by state and/or federal laws or regulations 
or judicial or other legal precedent of general application. Upon request, 
VALIC will promptly furnish to FUND the opinion of counsel for VALIC to the 
effect that any redemption pursuant to clause (ii) above is a legally required 
redemption. Furthermore, VALIC shall not prevent new Contract Participants from 
allocating payments to FUND that formerly was available under the Contracts 
without first giving FUND ninety (90) days notice of its intention to do so.

         17. Potential Conflicts.

             (a) The parties acknowledge that the Trust's shares may be made 
available for investment to other Participating Insurance Companies. In such 
event, the Trustees will monitor the Trust for the existence of any material 
irreconcilable conflict between the interests of the contract owners of all 
Participating Insurance Companies. A material irreconcilable conflict may arise 
for a variety of reasons, including: (a) an action by any state insurance 
regulatory or other authority; (b) a change in applicable federal or state 
insurance, tax, or securities laws or regulations, or a public ruling, private 
letter ruling, no-action or interpretative letter, or any similar action by 
insurance, tax, or securities regulatory authorities; (c) an administrative or 
judicial decision in any relevant proceeding; (d) the manner in which the 
investments of any portfolio are being managed; (e) a difference in voting 
instruction given by variable annuity contract and variable life insurance 
contract owners; or (f) a decision by an insurer to disregard the voting 
instructions of contract owners. The Trustees shall promptly inform the VALIC 
if they determine that a material irreconcilable conflict exists and the 
implications thereof. The Trustees shall have sole authority to determine 
whether a material irreconcilable conflict exists and their determination shall 
be binding upon the VALIC.

             (b) VALIC agrees to promptly report any potential or existing 
conflicts of which it is aware to the Trustees. VALIC will assist the Trustees 
in carrying out their responsibilities under the Shared Trust Exemptive Order 
and this Section 17 by providing the Trustees with all information reasonably 
necessary for them to consider any issues raised including, but not limited to, 
information as to a decision by the VALIC to disregard Contract Participant 
voting instructions.

             (c) If it is determined by a majority of the Trustees, or a 
majority of the disinterested Trustees, that a material irreconcilable conflict 
exists that affects the interest of Contract Participants, VALIC shall, in 
cooperation with other Participating Insurance Companies whose contract owners 
are also affected, at its expense and to the extent reasonably practicable (as 
determined by the Trustees) take whatever steps are necessary to remedy or 
eliminate the material irreconcilable conflict, which steps could include: (a) 
withdrawing the assets allocable to some of the Accounts from the Trust or any 
portfolio and reinvesting such assets in a different investment medium, 
including (but not limited to) another portfolio of the Trust, or submitting 
the question of whether or not such segregation should be implemented to a vote 
of all affected Contract Participants and, as appropriate, segregating the 
assets of any appropriate group (i.e. annuity contract owners, life insurance 
contract owners, variable annuity contract owners, or variable life insurance 
contract owners of one or more Participating Insurance Companies) that votes in 
favor of such segregation, or offering to the affected Contact Participants the 
option of making such change; and (b) establishing a new registered management 
investment company or managed separate account and obtaining any necessary 
approvals or orders of the Commission in connection therewith.

             (d) If any material irreconcilable conflict arises because a 
particular state insurance regulator's decision applicable to VALIC conflicts 
with the majority of other state regulators, then VALIC will withdraw the 
affected ACCOUNT investment in the Trust and terminate this Agreement with 
respect to such ACCOUNT within six (6) months after the Trust gives written 
notice that it has determined that such decision has created a material 
irreconcilable conflict; provided, however, that such withdrawal and 
termination shall be limited to the extent required by the foregoing material 
irreconcilable conflict as determined by a majority of the disinterested 
Trustees. Until the end of such six (6) month period, the Trust shall continue 
to accept and implement orders by VALIC for the purchase and redemption of 
shares of the Trust.

             (e) For purposes of (c) and (d) of this Section 17 of this 
Agreement, a majority of the disinterested Trustees shall determine whether any 
proposed action adequately remedies any material irreconcilable conflict. VALIC 
shall not be required by (c) of this Section 17 to establish a new funding 
medium for the Contracts if any offer to do so has been declined by a vote of a 
majority of Contract Participants materially adversely affected by the material 
irreconcilable conflict. In the event that the Trustees determine that any 
proposed action does not adequately remedy any material irreconcilable 
conflict, then VALIC will withdraw the ACCOUNT's investment in the Trust and
terminate this Agreement within six (6) months after the Trust gives written 
notice of the foregoing determination; provided, however, that such withdrawal 
and termination shall be limited to the extent required by any such material 
irreconcilable conflict, as determined by a majority of the disinterested 
Trustees.

             (f) VALIC shall at least annually submit to the submit to the 
Trustees such reports, materials or data as the Trustees may reasonably request 
so that the Trustees may fully carry out the duties imposed upon them by the 
Shared Trust Exemptive Order and this Section 17. Said reports, materials and 
data shall be submitted more frequently if deemed appropriate by the Trustees.

             (g) If and to the extent that Rule 6e-2 and Rule 6e-(T) are 
amended, or Rule 6e-3 is adopted, to provide exemptive relief from any provision
of the 1940 Act or the rules promulgated thereunder with respect to mixed and/or
shared funding (as defined in the Shared Trust Exemptive Order) on terms and
conditions materially different from those contained in the Shared Trust
Exemptive Order, then the Trust and/or the Participating Insurance Companies, as
appropriate, shall take such steps as may be necessary to comply with Rules 6e-2
and 6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such rules are
applicable.

             (h) If a material irreconcilable conflict arises because of a
decision by VALIC to disregard Contract Participant voting instructions as set
forth in Section 14 of this Agreement, and that decision represents a minority
position or would preclude a majority vote, VALIC may be required, at the
Trust's election, to withdraw the affected ACCOUNT's investment in the Trust and
terminate this Agreement with respect to such ACCOUNT; provided, however, that
such withdrawal and termination shall be limited to the extent required by the
foregoing material irreconcilable conflict as determined by a majority of the
disinterested Trustees. Any such withdrawal and termination must take place
within six (6) months after the Trust gives written notice that this provision
is being implemented. Until the end of such six (6) month period, the Trust
shall continue to accept and implement orders by VALIC for the purchase and
redemption of share of the Trust.

         18. Any notice shall be sufficiently given when sent by registered or
certified mail (return receipt requested) to the other party at the address of
such party set forth below or at such other address as such party may from time
to time specify in writing to the other party.
