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 the Company, the Contract, 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 the A.G.
Separate Account A are offered. The Contract will allow you to accumulate
retirement dollars in Fixed Account Options and/or Variable Account Options.
This prospectus describes only the variable aspects of the Contract 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
the Contract. It is intended to provide you with a brief overview of those
sections discussed in more detail in this prospectus.

                                                                               1

(1) OTHER EXPENSES includes custody, accounting, reports to shareholders, audit,
    legal, administrative and other miscellaneous expenses. See each Fund's
    prospectus for a detailed explanation of these fees.

(2) The Company has entered into certain arrangements under which it is
    compensated by the Fund's advisers or administrators for administrative
    services the Company provides to the Funds.


(3) The management fees reflect effective management fees after taking into
    effect any waiver. Other expenses are shown net of certain expense offsets
    afforded the Portfolio. Total annual portfolio operating expenses for the
    Portfolio are limited by OpCap Advisors so that their respective annualized
    operating expenses (net of expense offsets) do not exceed 1.00% of the
    Portfolio's average daily net assets. The gross expenses for the Portfolio
    are shown in the Fund Annual Expenses table above.


(4) Other Expenses for the Oppenheimer Small Cap Growth Fund/VA are net of
    voluntary assumption of 0.49% in Other Expenses by the Fund's adviser.

(5) On February 8, 2000, shareholders of the Templeton Developing Markets Fund
    approved a merger and reorganization that combined the Templeton Developing
    Markets Fund with the Templeton Developing Markets Equity Fund, effective
    May 1, 2000. At the same time as the merger, the Templeton Developing
    Markets Fund changed its name to the Templeton Developing Markets Securities
    Fund. The table shows restated total expenses for the Templeton Developing
    Markets Securities Fund based on the new fund fees and the assets of the
    Templeton Developing Markets Fund as of December 31, 1999, and not the
    assets of the combined fund. However, if the table reflected both the new
    fund fees and the fund's combined assets, the fund's expenses after May 1,
    2000 would be estimated as: Management Fees 1.25%, 12b-1 Fees 0.25%, Other
    Expenses 0.29%, and Total Annual Portfolio Expenses 1.79%.

(6) The fund's class 2 distribution plan or "rule 12b-1 plan" is described in
    the fund's prospectus.

(7) On February 8, 2000, shareholders of the Templeton International Fund
    approved a merger and reorganization that combined the Templeton
    International Fund with the Templeton International Equity Fund, effective
    May 1, 2000. At the same time as the merger, the Templeton International
    Fund changed its name to the Templeton International Securities Fund. The
    table shows restated total expenses for the Templeton International
    Securities Fund based on the new fund fees and the assets of the Templeton
    International Fund as of December 31, 1999, and not the assets of the
    combined fund. However, if the table reflected both the new fund fees and
    the fund's combined assets, the fund's expenses after May 1, 2000 would be
    estimated as: Management Fees 0.65%, 12b-1 Fees 0.25%, Other Expenses 0.20%,
    and Annual Expenses 1.10%.

(8) In the absence of management fee waiver, management fees, other expenses and
    total annual portfolio operating expenses, respectively, for the Van Kampen
    LIT Emerging Growth Portfolio would be: 0.70%, 0.18%, and 0.88%.

SUMMARY -- (CONTINUED)

A detailed description of the investment objective of each Fund can also be
found in each Fund's current prospectus.

GUARANTEED DEATH BENEFIT

The Contract offers a death benefit equal to the greater of:

- Net Purchase Payments (Purchase Payments less any partial surrenders), or

- Account Value as of the end of the Valuation Period immediately following
receipt of proof of death and the election of the death benefit payment.
TRANSFERS


You may transfer money in your account among the Contract's investment options
free of charge. We reserve the right, however, to impose a fee of $25 or 2% of
the amount transferred for each transfer which will be deducted from the amount
transferred. Transfers during the Purchase Period are permitted as follows:



- You may transfer your Account Value among the Variable Account Options once
  each day;



- You may transfer your Account Value from the One Year Fixed Account Option to
  one or more Variable Account Options once each day; and/or



- You may transfer your Account Value from one or more Variable Account Options
  into the One Year Fixed Account Option once each day, subject to a six month
  waiting period following any transfer of Account Value from the One Year Fixed
  Account Option into one or more Variable Account Options. (For example, if you
  make a transfer of Account Value from the One Year Fixed Account Option into
  the AGSPC Stock Index Fund Division 5 on January 1, of a Contract Year, you
  will not be allowed to transfer the Account Value in the AGSPC Stock Index
  Fund Division 5 back into the One Year Fixed Account Option until June 1, of
  such Contract Year.)


Once you begin receiving payments from your account (called the Payout Period),
you may still transfer funds among the Variable Account Options and from the
Variable Account Options to the One Year Fixed Account Option.

Transfers can be made by calling the Company's toll-free transfer service at
1-800-424-4990. For more information on account transfers, see the "Transfers
Between Investment Options" section in this prospectus.

FEES AND CHARGES

ACCOUNT MAINTENANCE FEE

On each Contract Anniversary, the Company deducts an Account Maintenance Fee of
$30 from your Account Value during the Purchase Period. The fee is deducted
proportionately from each investment option. If the Account Value on a Contract
Anniversary is at least $25,000, the Company will waive the fee for the
following Contract Year.

SURRENDER CHARGE


Under some circumstances a surrender charge is deducted from your account. These
situations are discussed in detail in the section of this prospectus entitled
"Fees and Charges -- Surrender Charge." When this happens the surrender charge
is computed as a percent of the total Purchase Payments withdrawn based on the
length of time from when each Purchase Payment was received up to a maximum of
7.0% of Purchase Payments.


Withdrawals are always subject to 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. For a
detailed discussion on timing and deduction of premium taxes see the section of
this prospectus entitled "Fees and Charges -- Premium Tax Charge."


SEPARATE ACCOUNT CHARGES

If you choose a Variable Account Option you will incur a mortality and expense
risk fee and an administration fee computed at an aggregate annualized rate of
0.70% and 0.15%, respectively, on the average daily net asset value of the A.G.
Separate Account A.

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.

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

FEDERAL TAX INFORMATION

Although deferred annuity contracts such as the Contract can be purchased with
after-tax dollars, they are also used in connection with retirement programs
which receive favorable tax treatment under federal law.

PURCHASE REQUIREMENTS

The minimum initial Purchase Payment for Non-Qualified Contracts is $5,000 and
for Qualified Contracts is $2,000. The minimum subsequent Purchase Payment is
$1,000 for Non-Qualified Contracts and $250 for Qualified Contracts. The minimum

GENERAL INFORMATION
--------------------------------------------------------------------------------

ABOUT THE CONTRACT

The Contract was developed to help you save money for your retirement. It offers
you a combination of fixed and variable options that you can invest in to help
you reach your retirement savings goals. Your contributions to the Contract can
come from different sources, like payroll deductions or money transfers. Your
retirement savings process with the Contract will involve two stages: the
Purchase Period; and the Payout Period. The first is when you make contributions
into the Contract called "Purchase Payments." The second, is when you receive
your retirement payouts. For more information, see "Purchase Period" and "Payout
Period" in this prospectus.

You may choose, depending upon your retirement savings goals and your personal
risk tolerances, 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 the Contract.

ABOUT A.G. SEPARATE ACCOUNT A

When you direct money to the Contract's Variable Account Options, you will be
sending that money through A.G. Separate Account A. You do not invest directly
in the Mutual Funds made available in the Contract. A.G. Separate Account A
invests in the Mutual Funds on behalf of your account. A.G. Separate Account A
is made up of what we call "Divisions." Fifteen Divisions are available and
represent the Variable Account Options in the Contract. Each of these Divisions
invests in a different Mutual Fund made available through the Contract. For
example, Division Twelve represents and invests in the Oppenheimer High Income
Fund/VA. 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 A.G. Separate Account A.

The Company established A.G. Separate Account A on November 9, 1994 under Texas
insurance law. Prior to May 1, 1999, A.G. Separate Account A was known as AGA
Separate Account A. A.G. Separate Account A is registered with the SEC as a unit
investment trust under the Investment Company Act of 1940 (1940 Act). Units of
interest in A.G. Separate Account A are registered as securities under the
Securities Act of 1933 (1933 Act).

A.G. Separate Account A is administered and accounted for as part of the
Company's business operations. However, the income, capital gains or capital
losses, whether or not realized, of each Division of A.G. 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 the Contract, A.G. Separate Account A may not be charged with the liabilities
of any other

Corporation has no legal obligation to back those commitments. When we discuss
performance information in this prospectus, we mean the performance of an A.G.

UNITS OF INTERESTS

Your investment in a Division of A.G. Separate Account A is represented by units
of interest issued by A.G. Separate Account A. On a daily basis, the units of
interests issued by A.G. Separate Account A are revalued to reflect that day's
performance of the underlying Mutual Fund minus any applicable fees and charges
to A.G. Separate Account A.

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 the Contract is surrendered before the Payout Period.

PURCHASE PAYMENTS

You may establish an account only through a registered representative. Initial
Purchase Payments must be received by the Company either with, or after, a
completed application. All Purchase Payments and sums payable to the Company
under the Contract must be sent to the Company's lock box at State Street Bank &
Trust Company at the following addresses: American General Annuity Insurance
Company, P.O. Box 5429, Boston, MA 02206-5429, if the Purchase Payments are sent
by mail; and State Street Bank and Trust Company, Attention Lock Box A3W, 1776
Heritage Drive, North Quincy, MA 02171, if the Purchase Payments are sent by
overnight delivery.

Minimum initial and subsequent Purchase Payments are as follows:

                                   Initial    Subsequent
                                   Purchase    Purchase

Qualified Contract                  $2,000      $  250
</TABLE>

Subject to the maximum and minimum Purchase Payment requirements, you may make
subsequent Purchase Payments and may increase or decrease or change the
frequency of such payments. The maximum total Purchase Payments we will accept
without our prior approval is $1,000,000.

You may select on your Contract application the Automatic Check Option. The
Automatic Check Option allows you to preauthorize debits against a bank account
that you indicate on the Preauthorized Debit Form to be sent in with your
Contract application. The minimum amount per a preauthorized debit Purchase
Payment under the Automatic Check Option is $50.

Purchase Payments are received at the Annuity Service Center. When an initial
Purchase Payment is accompanied by an application, within 2 business days we
will:

- Accept the Application -- and issue a contract.

- Reject the Application -- and return the Purchase Payment; or

- Request Additional Information -- to correct or complete the application. We
  will return the Purchase Payments within 5 business days if the requested
  information is not provided, unless you otherwise so specify.

In states where we are required by state law to refund an amount equal to
Purchase Payments, we invest your initial Purchase Payment and any additional
Purchase Payments in the Money Market Division from the date your investment
performance begins until the first business day 10 days later (may vary by
state). Then we will automatically allocate your investment among the investment
options you have chosen. See "Right to Return", below.

RIGHT TO RETURN


If for any reason you are not satisfied with your Contract, you may return it to
the Company and receive a refund of your Purchase Payments adjusted to reflect
(1) investment experience and (2) any Fees and Charges which have been deducted.
(In some states, we will return Purchase Payments as required by state law.) To
exercise your right to return your Contract, you must mail it directly to the
Annuity Service Center or return it to the registered representative through
whom you purchased the Contract within 10 days (may vary by state) after you
receive it. The address for the Annuity Service Center is located in the back of
this prospectus.


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.)
Once we have issued your Contract and have applied your initial Purchase Payment
as described above, any subsequent Purchase Payments received at the address
above before the close of the Exchange will be credited the same business day.
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
the Company to receive the
benefits of an annuity
offered by the Contract.

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.

                                                                              11
<PAGE>   14

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

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 under the Contract. This includes 3
Fixed Account Options and 15 Variable Account Options. The Funds that underlie
the Variable Account Options are registered as investment companies under and
are subject to regulation of the 1940 Act. The Fixed Account Options are not
subject to regulation under the 1940 Act and are not required to be registered
under the 1933 Act. 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. The DCA One Year Fixed
Account Option and the DCA Six Month Fixed Account Option are used exclusively
in connection with the Dollar Cost Averaging Program. See the "Dollar Cost
Averaging Program" section of 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 these Fixed Account Options at declared
rates, which may be different for each option. We bear the entire investment
risk for these Fixed Account Options. All Purchase Payments and interest earned
on such amounts in your Fixed Account Option(s) 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(s) 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. A complete discussion of each of the
Variable Account Options may be found in the "Summary" and "Variable Account
Options" sections 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 A.G. 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 Contract 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 $500, and you do not make any Purchase
Payments for 180 days we reserve the right to forward to your attention, written
notice that we will close your Account and pay the Account Value 90 days from
the date of notice if additional Purchase Payments are not made in amounts
sufficient to increase your Account Value to $500 or more.

TRANSFERS BETWEEN INVESTMENT OPTIONS
--------------------------------------------------------------------------------

You may transfer all or part of your Account Value between the various Fixed
Account and Variable Account Options in the Contract subject to the limitations
on transfers discussed below. 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.

DURING THE PURCHASE PERIOD

During the Purchase Period, transfers may be made among the Contract's Variable
Account Options and between the Variable Account Options and the One Year Fixed
Account Option free of charge. We reserve the right to impose a fee of the
lesser of $25 or 2% of the amount transferred for each transfer (which will be
deducted from the amount transferred).


Transfers during the Purchase Period are permitted as follows:



- You may transfer your Account Value among the Variable Account Options once
  each day;



- You may transfer your Account Value from the One Year Fixed Account Option to
  one or more Variable Account Options once each day; and/or



- You may transfer your Account Value from one or more Variable Account Options
  into the One Year Fixed Account Option once each day, subject to a six month
  waiting period following any transfer of Account Value from the One Year Fixed
  Account Option into one or more Variable Account Options. (For example, if you
  make a transfer of Account Value from the One Year Fixed Account Option into
  the AGSPC Stock Index Fund Division 5 on January 1, of a Contract Year, you
  will not be allowed to transfer the Account Value in the AGSPC Stock Index
  Fund Division 5 back into the One Year Fixed Account Option until June 1, of
  such Contract Year.)


The minimum amount to be transferred in any one transfer is $250 or the entire
amount in the Variable Account Option or One Year Fixed Account Option from
which the transfer is made. If a transfer request would reduce your Account
Value in a Variable Account Option or the One Year Fixed Account Option below
$500, we will transfer your entire Account Value in that Variable Account Option
or the One Year Fixed Account Option.

Transfers from the One Year Fixed Account Option to a Variable Account Option
are limited to 20%, per Contract Year, of the Account Value of the One Year
Fixed Account Option. This 20% per Contract Year limit is determined as of the
immediately preceding Contract Anniversary.

We currently do not permit transfers from the Variable Account Options to the
DCA Fixed Account Options. Transfers from the DCA Fixed Account Options may only
be made under the Dollar Cost Averaging Program. See the "Dollar Cost Averaging
Program" -- section of this prospectus.

DURING THE PAYOUT PERIOD

During the Payout Period, transfers may be made between the Variable Account
Options and from the Variable Account Options to the One Year Fixed Account
Option. We will not permit transfers from any Fixed Account Option during the
Payout Period. We reserve the right to impose a fee of the lesser of $25 or 2%
of the amount transferred for each transfer (which will be deducted from the
amount transferred). The minimum amount to be transferred during the Payout
Period is $250.

Transfers during the Payout Period are permitted subject to the following
limitations:

(1) The Company may change the number of transfers permitted to no more than six
    (6) transfers per year during the Payout Period.
(2) Currently, no transfer fee is imposed on transfers. The Company reserves the
    right to impose such a fee in the future which will not exceed the lesser of
    $25 or 2% of the amount transferred.

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 the Company may give telephone
instructions on your behalf without the Company's prior written permission.
(This does not apply to a contract with the immediate family of an employee or
representative of the Company).

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.

SWEEP ACCOUNT PROGRAM

During the Purchase Period you may elect to participate in the Sweep Account
Program if your Account Value in the One Year Fixed Account Option is at least
$25,000 on the date that the request for the Sweep Account Program is received
by us at the Annuity Service Center. The Sweep Account Program allows you to
transfer the earnings from the One Year Fixed Account Option to the Variable
Account Options. The transfers can be made on a quarterly, monthly, semi-annual
or annual basis. All amounts transferred must be in whole percentages, with a
10% minimum to be transferred to each selected Variable Account Option(s). There
is no charge for the Sweep Account Program. We do not take into account
transfers made pursuant to the Sweep Account Program in assessing any transfer
fee.

EFFECTIVE DATE OF TRANSFER

The effective date of a transfer will be:

- The date of receipt, if received at our Annuity Service Center 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.

RESERVATION OF RIGHTS AND MARKET TIMING

If a transfer causes your Account Value in the One Year Fixed Account Option or
a Variable Account Option to fall below $500, we may transfer the remaining
Account Value in the same proportions as your transfer request.

We may defer any transfer from the One Year Fixed Account Option to the Variable
Account Options for up to six months.


The Contracts are not designed for professional market timing organizations or
other entities using programmed and/or frequent transfers. We reserve the right
at any time and without prior notice to any party to terminate, suspend, or
modify our policies or procedures regarding frequent transfer requests.


DOLLAR COST AVERAGING PROGRAM

You may elect the Dollar Cost Averaging Program which permits the systematic
transfer of your Account Value from a Fixed Account Option or the Money Market
Division to one or more Variable Account Options not including the Money Market
Division. By allocating amounts on a regularly scheduled basis, as opposed to
allocating the total amount at one particular time, you may be less susceptible
to the effect of market fluctuations. We currently provide three Fixed Account
Options, two of which, the DCA One Year Fixed Account and the DCA Six Month
Fixed Account, are available only for dollar cost averaging.

We determine the amount of transfers from a DCA Fixed Account Option or the
Money Market Division by dividing the Purchase Payments allocated to that DCA
Fixed Account Option or the Money Market Division by a factor based on the
number of months remaining in the term. Transfers from a DCA Fixed Account
Option or the Money Market Division are only available on a monthly basis. We
require that you specify each allocation to a Variable Account Option, not
including the Money Market Division, in whole percentages using a maximum of 10
Variable Account options. The minimum amount to be transferred into a Variable
Account Option is 10% of the entire amount transferred.

<PAGE>   17
--------------------------------------------------------------------------------

We will transfer your entire Account Value in a DCA Fixed Account Option by the
expiration of its term. The minimum amount to be transferred under the Dollar
Cost Averaging Program is $250 per transfer. We currently do not permit
transfers to either DCA Fixed Account from the Variable Account Options or the
One Year Fixed Account Option.


You may enroll in dollar cost averaging for the DCA Fixed Account Options only
when you make initial or subsequent Purchase Payments. If you choose the DCA
Fixed Account Options, then dollar cost averaging will only apply to the
Purchase Payment portion of your Account Value. However, you may enroll in
dollar cost averaging for the Money Market Division at any time. If you choose
the Money Market Division for dollar cost averaging it must be for at least a 12
month period. There is no charge for dollar cost averaging. We do not take into
account transfers made pursuant to the Dollar Cost Averaging Program in
assessing any transfer fee.


The chart below explains the different Account Options you may choose if you
elect to participate in the Dollar Cost Averaging Program offered by the
Contract:

(1) You will not be permitted to transfer Account Value into a DCA Fixed Account
    Option once the entire Account Value has been transferred out of a DCA Fixed
    Account Option.


(2) The Dollar Cost Averaging Program will only apply to the Purchase Payment
    portion of your Account Value.


PORTFOLIO REBALANCING PROGRAM

From time to time, we will make available a portfolio rebalancing program which
provides for periodic pre-authorized automatic transfers among the Variable
Account Options pursuant to your written allocation instructions. We will make
such transfers to maintain a specified percentage allocation of Account Value
among the Variable Account Options as selected by you. We require each
allocation to a Variable Account Option equal at least 1% of Account Value.


The portfolio rebalancing program will begin on the date that your request for
portfolio rebalancing is received by us at the Annuity Service Center. You may
select rebalancing to occur on a monthly, quarterly, semi-annual, or annual
basis, and currently, all Variable Account Options are available for portfolio
rebalancing. The Fixed Account Options do not participate in portfolio
rebalancing.


There is no charge for portfolio rebalancing. We do not take into account
transfers made pursuant to the Portfolio Rebalancing Program in assessing any
transfer fee.

                                                                              15

FEES AND CHARGES
--------------------------------------------------------------------------------

By investing in the Contract, 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 Charges
- 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 $30 will be deducted on each Contract Anniversary
from your Account Value during the Purchase Period. If all your money in the
Contract is withdrawn, the fee will be deducted at that time. The fee will be
assessed equally among the Variable Account and Fixed 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 and Fixed Account Options. This includes
the expense for establishing and maintaining the recordkeeping for your
Contract.

During the Purchase Period, if your Account Value on a Contract Anniversary is
at least $25,000, we will waive the account maintenance fee for the next
Contract Year.

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 Purchase Payments are withdrawn first under the concept
of first-in, first-out. No surrender charge will be applied unless an amount is
actually withdrawn.

We calculate the surrender charge by multiplying the applicable percentages
specified in the table below by the Purchase Payments withdrawn.

Amount of Surrender Charge

A surrender charge may not be greater than:

<TABLE>
<CAPTION>
   NUMBER OF YEARS
        SINCE
  DATE OF PURCHASE       CHARGE AS PERCENTAGE OF
       PAYMENT          PURCHASE PAYMENT WITHDRAWN

          2                         7%
          3                         5%
          4                         5%
          5                         4%
          6                         2%
          7+                        0%
</TABLE>

10% Free Withdrawal

For each Contract Year after the first Contract Year, up to 10% of the Account
Value, determined as of the immediately preceding Contract Anniversary (or if
during the first Contract Year, the date the Contract is issued), may be
withdrawn once each Contract Year 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, determined as of the immediately preceding Contract Anniversary.


If a surrender charge is applied to all or part of a Purchase Payment, then your
Purchase Payment (or portion thereof) will be considered withdrawn, and no
surrender charge will be applied to such Purchase Payment (or portion thereof)
again.


The 10% free withdrawal requires a minimum withdrawal of $100, or if less, the
entire Account Value. The minimum amount which must remain in each Division in
which you are invested, after a withdrawal, is $500.

EXCEPTIONS TO SURRENDER CHARGE

No surrender charge will be applied:

- To death benefits;

- To Payout Payments; and

- To partial surrenders through the Systematic Withdrawal Program, in lieu of
  the 10% free withdrawal, during the first Contract Year, see the "Surrender of
  Account Value" section of this prospectus.

CONTRACT ANNIVERSARY -- the
date that the contract
is issued and each
yearly anniversary
of that date thereafter.

CONTRACT YEAR -- the first
twelve month period and
then each yearly anniversary
of that period following the
issue date of the contract.

 16
<PAGE>   19
--------------------------------------------------------------------------------

PREMIUM TAX CHARGE

Taxes on Purchase Payments are imposed by some states, cities, and towns.
Currently, rates range from zero to 3.5%.

The timing of tax levies varies from one taxing authority to another. If premium
taxes are applicable to a Contract, we will deduct such tax against Account
Value in a manner determined by us in compliance with applicable state law. We
may deduct an amount for premium taxes either upon:

- receipt of the Purchase Payments;

- the commencement of Payout Payments;

- surrender (full or partial); or

- the payment of death benefit proceeds.

SEPARATE ACCOUNT CHARGES

There will be a mortality and expense risk fee and an administration fee applied
to A.G. Separate Account A. These are daily charges at annualized rates of 0.70%
and 0.15%, respectively, on the average daily net asset value of A.G. Separate
Account A. Each 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 the Contract. 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, a death benefit. For more
information about the death benefit see the "Death Benefit" section of this
prospectus. The expense risk is our obligation to cover the cost of issuing and
administering the Contract, 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 fee.

The administration fee is to reimburse the Company for our administrative
expenses under the Contract. This includes the expense of administration and
marketing (including but not limited to enrollment and Contract Owner
education).

For more information about the mortality and expense risk fee and administration
fee, see the Fee Table in 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.

                                                                              17
<PAGE>   20

PAYOUT PERIOD
--------------------------------------------------------------------------------

The Payout Period begins when you decide to withdraw your money in a steady
stream of payments. You select the date to begin the Payout Period, the Payout
Date. 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)(2);

  - 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.

(2) Not applicable for certain 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. 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% is
used. If the net investment experience of the Variable Account Option exceeds
the 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 can divide your Account Value
between:

  - Variable Payout, from your existing Variable Account Options (payments will
    vary); and

  - Fixed Payout (payment is fixed and guaranteed).

PAYOUT DATE

The Payout Date is the date elected by you on which your payout payments will
start and is subject to our approval. The Payout Date must be at least four
years after the date that the Contract is issued. You may change the Payout Date
subject to our approval. We will notify you of the approaching Payout Date 60 to
90 days prior to such date. Unless you select a Payout Date, we will
automatically extend the Payout Date to begin at the later of when you attain
age 85 or ten years after we issue the Contract. 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. However, the date may
be later for participants in 403(b) plans. Non-qualified annuities do not have a
specific date. For additional information on the minimum distribution rules that
apply to payments under IRA or 403(b) plans, 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 PERIOD CERTAIN -- 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
A.G. 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).

 18
<PAGE>   21

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

   - JOINT AND SURVIVOR LIFE -- payments are made to you during the joint
     lifetime of you and your joint annuitant. Upon the death of either you or
     your joint annuitant, payments continue during the lifetime of the
     survivor. This option is designed primarily for couples who require 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.
     Additionally, it would be possible 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.

   PAYOUT INFORMATION

   Once your Payout Payments have begun, the option you have chosen may not be
   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 if you do not meet an
   exception to federal tax law. See "Federal Tax Matters" in this prospectus.

   Your Payment Option should be selected at least 15 days before your Payout
   Date. If such
selection is not made and state or federal law does not require the selection of
the Joint and Survivor Life Option:

  - Payments will be made under the Life with Period Certain Option,

  - The payments will be guaranteed for a 10 year period,

  - The payments will be based on the allocation used for your Account Value,

  - The non-DCA 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.

Most Payout Payments are made monthly; however, Payout Payments may also be made
as quarterly, semiannual or annual installments. If you have chosen either a
Fixed or Variable Payout Option and if the amount of your payment is less than
$200, we reserve the right to reduce the number of payments made each year so
each of your payments is at least $200. If you have chosen a combination of
Fixed and Variable Payout Options and the amount of your payment is less than
$100, we reserve the right to reduce the number of payments made each year so
each of your payments is at least $100.

For more information about
PAYOUT OPTIONS
available under the Contract,
see the Statement of
Additional Information.

                                                                              19

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/or

  - allowed under your retirement plan.

For an explanation of charges that may apply if you surrender your Account
Value, see "Fees and Charges" in this prospectus.

You may be subject to a 10% federal tax penalty for partial or total surrenders
made before age 59 1/2, see "Federal Tax Matters" 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>

                          = (EQUALS)         Surrender
                                            Charge, any
                                         applicable taxes
                                            and Account
                                          Maintenance Fee
</TABLE>

  (1) Equals the Account Value next computed after your properly completed
      request for surrender is received at the Annuity Service Center.

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 the Annuity Service Center.
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, no surrender or partial
surrender will be allowed except for attainment of age 70 1/2, retirement or
other termination of employment or death.

PARTIAL SURRENDER

You may request a partial surrender of your Account Value at any time during the
Purchase Period. A partial surrender plus any surrender charge will reduce your
Account Value.

To process your partial surrender, you may specify the Account Value that should
be deducted from each investment option. If you fail to provide us with this
information, we may deduct the partial surrender from each investment option in
which your Account Value is held on a pro rata basis.

The minimum partial surrender we will allow is $500 or your entire Account
Value, if less.

We reserve the right to defer the payment of a partial surrender from the One
Year Fixed Account Option for up to six months. We currently do not permit
partial surrenders from the DCA Fixed Account Options.

SYSTEMATIC WITHDRAWAL PROGRAM

The Systematic Withdrawal Program allows you to make withdrawals in a Contract
Year of up to 10% of your Account Value without the imposition of a surrender
charge. If you withdraw more than 10% of your Account Value, you will be subject
to a surrender charge. Account Value, for purposes of the Systematic Withdrawal
Program, is determined as of the immediately preceding Contract Anniversary or,
if during the first Contract Year, the date we issue you the Contract. See the
"Fees and Charges" section in this prospectus.

You may elect to withdraw all or part of your Account Value under a systematic
withdrawal method described in your Contract. Withdrawals using this method are
eligible for the 10% free withdrawal privilege each Contract Year. The
Systematic Withdrawal Program provides for:

  - Payments to be made to you;

  - Payment over a stated period of time;

  - Payment of a stated yearly dollar amount or percentage.

We may require a minimum withdrawal of $100 per withdrawal under this method.
The portion of your account that has not been withdrawn will continue to receive
the investment return of the Variable Account Option or the

 20
<PAGE>   23
--------------------------------------------------------------------------------

Fixed Account Option that you selected. A systematic withdrawal election may be
changed or revoked at no charge. 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.

See "Federal Tax Matters" in this prospectus and in the Statement of Additional
Information for more information about required distributions imposed by tax
law.

We issue other fixed and/or variable annuity contracts (other contracts) in
addition to ElitePlus Value. We will allow you, under certain conditions, to
exchange from one of these other contracts to ElitePlus Value. If you elect to
exercise an exchange, you should contact our Annuity Service Center at the

RESTRICTIONS ON EXCHANGE PRIVILEGE

We will impose certain general restrictions and rules on the exchange
privileges.

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 ElitePlus Value. Please read the
"Transfers Between Account Options" section in this prospectus.

WE RESERVE THE RIGHT TO
TERMINATE, MODIFY OR SUSPEND
THESE EXCHANGE PRIVILEGES AT ANY TIME.

CHARGES AND TAXES

maintenance fee and certain other fees and charges. These charges will be
incurred even though you may not have them on the contract you were in before
your exchange into ElitePlus Value. Please read the "Fees and Charges" section

DEATH BENEFITS
--------------------------------------------------------------------------------

The Contract will pay a death benefit during either the Purchase Period or the
Payout Period. How the death benefit will be paid is discussed below. The death
benefit provisions in the Contract may vary from state to state.

BENEFICIARY INFORMATION

The Beneficiary may receive death benefits:

- In a lump sum; or

- Payment of the entire death benefit within 5 years of the date of death; 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.

SPECIAL INFORMATION FOR NON-TAX QUALIFIED CONTRACTS

It is possible that the Contract Owner and the Annuitant under a Non-Qualified
Contract are not the same person. If this is the case, and the Contract Owner
dies, death benefits must be paid:

- within 5 years of the date of death; or

- beginning within 1 year of the date of death under:

  - a life annuity with or without a period certain, or

  - an annuity for a designated period not extending beyond the life expectancy
    of the Beneficiary.

JOINT OWNER SPOUSAL ELECTION INFORMATION

The Beneficiary will receive the Death Benefit payout if:

- the Contract Owner dies before the Payout Date, or

- the Annuitant dies during the Annuity Period.

If the Annuitant dies before the Annuity date, the Owner may designate a new
Annuitant or become the Annuitant.

With regard to Joint Owners of a Non-Qualified Contract, the Death Benefit is
payable upon the death of either Owner during the Purchase Period. However, in
the event of your death where the sole Beneficiary of the Non-Qualified Contract
is your spouse, your spouse may continue the Contract as Owner, in lieu of
receiving the Death Benefit.

DURING THE PURCHASE PERIOD

If death occurs before your 80th birthday, then the Death Benefit during the
Purchase Period will be the greater of:

DURING THE PAYOUT PERIOD

If the Annuitant dies during the Payout Period, your Beneficiary may receive any
continuing payments under the Payout Option that you selected. The Payout
Options available in the Contract are described in the "Payout Period" section
of this prospectus.

BENEFICIARY -- the person
designated to receive Payout
Payments or the Account Value
upon the death of
an Annuitant or the Owner.

ANNUITANT -- the individual,
(in most cases this person is
you) to whom Payout
Payments will be paid. The
Annuitant is also the
measuring life for the Contract.

FIXED ACCOUNT OPTIONS -- a
particular subaccount into
which your Purchase
Payments and Account Value
may be allocated to fixed
investment options.  Currently,
there are three Fixed
Account Options: the One Year
Fixed Account Option; the DCA
Six Month Fixed Account
Option; and the DCA One Year
Fixed Account Option. The
One Year Fixed Account Option
is guaranteed to earn at least a
minimum rate of interest.

VARIABLE ACCOUNT
OPTIONS -- Investment
Options that correspond to
A.G. Separate Account A
Divisions offered by the
Contract. Investment returns
on Variable Account Options
will be positive or negative
depending on the investment
performance of the
underlying mutual fund.

CONTRACT ANNIVERSARY -- the
date that the contract
is issued and each
yearly anniversary
of that date thereafter.

                                                                              23

HOW TO REVIEW INVESTMENT PERFORMANCE
OF SEPARATE ACCOUNT DIVISIONS
--------------------------------------------------------------------------------

We will advertise information about the investment performance of the A.G.
Separate Account A Divisions. Our advertising of the 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 or currently are available through other annuity or life insurance
contracts. 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 the Contract in calculating the Division's investment
performance.

TYPES OF INVESTMENT PERFORMANCE
INFORMATION ADVERTISED

We may advertise the Divisions' 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 the Contract
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, 5 and 10 year periods. If Standard
Average Annual Total Return for a Division is not available for a stated period,
we may show the Standard Average Annual Total 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 1-7, 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 the Contract will stay in the
Division beyond the time that a surrender charge would apply. It may be
calculated for 1, 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.

DIVISIONS -- subaccounts of
A.G. Separate Account A
which represent the Variable
Account Options in the
Contract. 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
the Company to receive the benefits
of an annuity Contract offered
by the Contract.

For more information on how
TOTAL RETURN PERFORMANCE
INFORMATION is calculated,
see the Statement of
Additional Information.

<PAGE>   27

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

ANNUAL CHANGE IN PURCHASE UNIT VALUE

Annual Change in Purchase Unit Value is a percentage change during a one year
period. 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 year;

  - The difference is divided by the Purchase Unit Value at the start of the
    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
Contract 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 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 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.

DIVISIONS OTHER THAN MONEY MARKET FUND DIVISIONS

We may advertise the standardized yield performance for each Division. The yield
for each Division 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 AND CUMULATIVE RETURN TABLES.

In the sections above we have described a number of ways we may advertise
information about the investment performance of A.G. Separate Account A
Divisions. Certain performance information for each A.G. Separate Account A
Division is printed in the three tables below.

The information presented does not reflect the advantage under the Contract of
deferring federal income tax on increases in Account Value due to earnings
attributable to Purchase Payments (see "Federal Tax Matters" in this 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 Contract owner.

  * 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 the historical performance
    of each Fund based on investment in a hypothetical Contract from the date of
    the Fund's inception. 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 Standard
    Average Annual Total Return for Divisions 1-7 will be shown when it becomes
    available.

(1) On September 16, 1994, an investment company which had commenced operations
    on August 1, 1988, then called Quest For Value Accumulation Trust (the "Old
    Trust") was effectively divided into two investment funds, the Old Trust and
    the present OCC Accumulation Trust (the "New Trust"), at which time the New
    Trust commenced operations. The total net assets of the Managed Portfolio
    immediately after the transaction were $682,601,380 with respect to the Old
    Trust and $51,345,102 with respect to the New Trust. For the period prior to
    September 16, 1994, the performance figure for the Managed Portfolio
    reflects the performance of the corresponding Managed Portfolio of the Old
    Trust.

(2) Effective May 1, 2000 the Templeton Developing Markets Fund merged with the
    Templeton Developing Markets Equity Fund. At the same time as the merger,
    the Templeton Developing Markets Fund changed its name to the Templeton
    Developing Markets Securities Fund. Accordingly, the performance figures in
    the Table for the Fund through March 31, 2000, reflect the historical
    performance and inception date of the Templeton Developing Markets Fund.
    Additionally, performance for Class 2 shares reflects a blended figure,
    combining: (a) for periods prior to Class 2's inception of May 1, 1997,
    historical results of Class 1 shares; and (b) for periods after May 1, 1997,
    Class 2's results reflecting an additional 12b-1 fee expense which also
    affects all future performance. Blended figures assume reinvestment of
    dividends and capital gains.

(3) Effective May 1, 2000 the Templeton International Fund merged with the
    Templeton International Equity Fund. At the same time as the merger, the
    Templeton International Fund changed its name to the Templeton International
    Securities Fund. Accordingly, the performance figures in the Table for the
    Fund through March 31, 2000, reflect the historical performance and
    inception date of the Templeton International Fund. Additionally,
    performance for Class 2 shares reflects a blended figure, combining: (a) for
    periods prior to Class 2's inception of May 1, 1997, historical results of
    Class 1 shares; and (b) for periods after May 1, 1997, Class 2's results
    reflecting an additional 12b-1 fee expense which also affects all future
    performance. Blended figures assume reinvestment of dividends and capital
    gains.

  * 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 the historical performance
    of each Fund based on investment in a hypothetical Contract from the date of
    the Fund's inception. 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 Standard
    Average Annual Total Return for Divisions 1-7 will be shown when it becomes
    available.

(1) On September 16, 1994, an investment company which had commenced operations
    on August 1, 1988, then called Quest For Value Accumulation Trust (the "Old
    Trust") was effectively divided into two investment funds, the Old Trust and
    the present OCC Accumulation Trust (the "New Trust"), at which time the New
    Trust commenced operations. The total net assets of the Managed Portfolio
    immediately after the transaction were $682,601,380 with respect to the Old
    Trust and $51,345,102 with respect to the New Trust. For the period prior to
    September 16, 1994, the performance figure for the Managed Portfolio
    reflects the performance of the corresponding Managed Portfolio of the Old
    Trust.

(2) Effective May 1, 2000 the Templeton Developing Markets Fund merged with the
    Templeton Developing Markets Equity Fund. At the same time as the merger,
    the Templeton Developing Markets Fund changed its name to the Templeton
    Developing Markets Securities Fund. Accordingly, the performance figures in
    the Table for the Fund through March 31, 2000, reflect the historical
    performance and inception date of the Templeton Developing Markets Fund.
    Additionally, performance for Class 2 shares reflects a blended figure,
    combining: (a) for periods prior to Class 2's inception of May 1, 1997,
    historical results of Class 1 shares; and (b) for periods after May 1, 1997,
    Class 2's results reflecting an additional 12b-1 fee expense which also
    affects all future performance. Blended figures assume reinvestment of
    dividends and capital gains.

(3) Effective May 1, 2000 the Templeton International Fund merged with the
    Templeton International Equity Fund. At the same time as the merger, the
    Templeton International Fund changed its name to the Templeton International
    Securities Fund. Accordingly, the performance figures in the Table for the
    Fund through March 31, 2000, reflect the historical performance and
    inception date of the Templeton International Fund. Additionally,
    performance for Class 2 shares reflects a blended figure, combining: (a) for
    periods prior to Class 2's inception of May 1, 1997, historical results of
    Class 1 shares; and (b) for periods after May 1, 1997, Class 2's results
    reflecting an additional 12b-1 fee expense which also affects all future
    performance. Blended figures assume reinvestment of dividends and capital
    gains.

WE RESERVE CERTAIN RIGHTS

We reserve the right to:

  - Amend the Contract to conform with substitutions of investments;

  - Amend the Contract to comply with tax or other laws;

  - Operate A.G. Separate Account A as a management investment company under the
    1940 Act, in consideration of an investment management fee or in any other

<PAGE>   32

VOTING RIGHTS
--------------------------------------------------------------------------------

As discussed in the "About A.G. Separate Account A" section of this prospectus,
A.G. 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 Contract Owner, you may be entitled to give voting instructions to
us as to how A.G. 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. Contract Owners will instruct A.G.
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 the Contract 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 the Contract may have a
number
of shareholders including A.G. Separate Account A, the Company, other affiliated
insurance company separate accounts and retirement plans within the American
General group of companies and public shareholders.

A.G. 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 Contract
Owners invested in that Fund entitled to give instructions at that shareholder
meeting. A.G. 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.

The Company will vote the shares of the Funds it holds based on, and in the same
proportion as, the voting instructions received from Contract Owners.

In the future, we may decide how to vote the shares of the Company or A.G.
Separate Account A in a different manner if permitted at that time under federal
securities law.

CONTRACT OWNER -- the person
entitled to the ownership rights
as stated in this prospectus.

A.G. SEPARATE
ACCOUNT A -- a segregated
asset account established by
the Company under the Texas
Insurance Code. The purpose
of A.G. Separate Account A
is to receive and invest your
Purchase Payments and
Account Value in the Variable
Account Options you have
selected.

FEDERAL TAX MATTERS
--------------------------------------------------------------------------------

The Contract provides tax-deferred accumulation over time, but is subject to
federal income and federal 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 federal 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 Section 408(b) IRA or is instead
a nonqualified Contract. The Contract 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 408(b) individual retirement annuities.

The foregoing Contracts are "Qualified Contracts." Certain series of the
Contract may also be available through a nondeductible Section 408A "Roth"
individual retirement annuity.

Note that the specific terms of the governing employer plan may limit rights and
options otherwise available under a Contract.

In addition, the Contract 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 that 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 the Contract 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 the Company can provide no assurance that such
limitations would not be imposed on a retroactive basis to contracts issued
under this prospectus. However, the Company has no present indication that the
IRS intends to impose such limitation, or what the terms or scope of those
limitations might be.

Distributions are taxed differently depending on the program through which the
Contract is offered and the previous tax characterization of the contributions
to which the distribution relates. Generally, the portion of a distribution that
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 under the circumstances
described in the Statement of Additional Information. Generally, distributions
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

                                                                              31
<PAGE>   34

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

Contracts may be subject to state income tax withholding requirements.

Investment earnings on contributions to Non-Qualified Contracts that 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:

  - The 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 tax qualified plan such as a
403(b) annuity. The chart assumes a 28% tax rate and an 8% fixed rate of return.
Variable options incur mortality and expense risk fee and administration fee
charges and may also incur account maintenance fees and surrender charges. The
chart does not reflect the deduction of any such fees. An additional 10% penalty
tax 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 qualified retirement
programs and Non-Qualified Contracts generally provide tax deferred treatment on
earnings. In addition, Premium Payments made to tax qualified retirement
programs ordinarily are not subject to federal income tax until withdrawn. As
shown above, investing in a tax qualified 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 qualified 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 QUALIFIED PROGRAM WILL BE
REDUCED BY THE IMPACT OF FEDERAL 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 federal income taxes,
contributions to tax qualified 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 across
illustrates this principle by comparing a pre-tax contribution to a tax
qualified retirement plan with an after-tax contribution to a conventional
savings account:

</TABLE>

This chart assumes a 28% federal income tax rate. The $560 that is paid toward
current federal income taxes reduces the actual amount saved in the conventional
savings account to $1,440 while the full $2,000 is contributed to the
tax-qualified program, subject to being taxed upon withdrawal. Stated otherwise,
to reach an annual retirement savings goal of $2,000, the contribution to a
tax-qualified retirement program results in a current out-of-pocket expense of
$1,440 while the contribution to a conventional savings account requires the
full $2,000 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.

Section of this Statement of Additional Information.

ENDORSEMENTS AND
PUBLISHED RATINGS

     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.

statistical data about the investment company industry in the United States.

                                        4
<PAGE>   45

     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 Variable Annuity Research
& Data Services (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

     The Contracts offered in connection with the prospectus to which this
Statement of Additional Information relates, are flexible payment deferred
annuity Contracts.

     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. Purchase Payments are invested and
accumulate on a fixed or variable basis until the date the Contract Owner
selects to commence annuity payments.

     The majority of these Contract will be sold to individuals through
financial institutions in the Non-Qualified market. A smaller number of these
contracts will be sold in the Qualified market through 403(b) plans and certain
IRA situations.

     The Contracts are non-participating and will not share in any of the
profits of the Company.

VARIABLE ANNUITY CONTRACT GENERAL PROVISIONS

     THE CONTRACT: The entire Contract consists of the Contract, the
Application, if any, and any riders or endorsements attached to the Contract.
The Contract may be changed or altered only by an authorized officer of the
Company. A change or alteration must be made in writing.

     MINIMUM CONTRACT VALUE: If the minimum Contract Value falls below the
minimum Contract Value shown in the Contract, then the Company reserves the
right to surrender the Contract and pay the Contract Value to the Owner.

     MISSTATEMENT OF AGE OR SEX: If the Age or sex of any Annuitant has been
misstated, any Annuity benefits payable will be the Annuity benefits provided by
the correct Age or sex. After Annuity Payments have begun, any underpayments
will be made up in one sum with the next Annuity Payment. Any overpayments will
be deducted from future Annuity Payments until the total is repaid.


     INCONTESTABILITY: The Contract is incontestable. The provisions of the
Contract can not be contested.


     MODIFICATION: The Contract may be modified in order to maintain compliance
with applicable state and federal law. When required, the Company will obtain
the Owner's approval of changes and gain approval from appropriate regulatory
authorities.

     NON-PARTICIPATING: The Contract will not share in any distribution of
dividends.

     EVIDENCE OF SURVIVAL: The Company may require satisfactory evidence of
continued survival of any person(s) on whose life Annuity Payments are based.

     PROOF OF AGE: The Company may require evidence of Age of any Annuitant or
Owner.

     PROTECTION OF PROCEEDS: To the extent permitted by law, death benefits and
Annuity Payments shall be free from legal process and the claim of any creditor
if the person is entitled to them under the Contract. No payment and no amount
under the

                                        5
<PAGE>   46

Contract can be taken or assigned in advance of its payment date unless the
Company receives the Owner's written consent.

     REPORTS: At least once each calendar year, the Company will furnish the
Owner with a report showing the Contract Value as of a date not more than four
months prior to the date of mailing, and will provide any other information as
may be required by law. Reports will be sent to the last known address of the
Owner.

     TAXES: Any taxes paid to any governmental entity relating to the Contract
will be deducted from the Purchase Payment or Contract Value when incurred. The
Company will, in its sole discretion, determine when taxes have resulted from:
the investment experience of the Separate Account; receipt by the Company of the
Purchase Payments; or commencement of Annuity Payments. The Company may, in its
sole discretion, pay taxes when due and deduct that amount from the Contract
Value at a later date. Payment at an earlier date does not waive any right the
Company may have to deduct amounts at a later date. While the Company is not
currently maintaining a provision for federal income taxes with respect to the
Separate Account, the Company has reserved the right to establish a provision
for income taxes if it determines, in its sole discretion, that it will incur a
tax as a result of the operation of the Separate Account. The Company will
deduct for any income taxes incurred by it as a result of the operation of the
Separate Account whether or not there was a provision for taxes and whether or
not it was sufficient. The Company will deduct any withholding taxes required by
applicable law.

     REGULATORY REQUIREMENTS: All values payable under the Contract, including
any paid-up annuity, cash withdrawal or death benefits that may be available,
will not be less than the minimum benefits required by the laws and regulations
of the state in which the Contract is delivered.

FEDERAL TAX MATTERS

     This Section summarizes the major tax consequences of contributions,
payments, and withdrawals under the Contracts, 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 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
$10,500 ($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, employer contributions for highly compensated employees
may be further limited by applicable nondiscrimination rules.

     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 may be made 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 $32,000 (Year 2000 figure) or less ($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 $52,000 (Year 2000 figure) or less ($40,000 or
      less prior to in 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
                                        6
<PAGE>   47

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 rollover contributions to an IRA 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 $10,000 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.


     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 cannot
exceed the lesser of $30,000 or 25% 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. 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.


     Savings Incentive Match Plan for Employees ("SIMPLE"). 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 A.G.
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 annual 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 ac-

                                        7
<PAGE>   48

count (other than rollover contributions). Contributions which are not subject
to these restrictions, such as employee contributions to a Section 403(b)
annuity, may be subject to restrictions under the sponsoring employer's plan, if
any. Distributions are taxed as ordinary income to the recipient in accordance
with Section 72.

     408(b) IRA, SEPs and SIMPLE IRAs. Distributions are generally taxed as
ordinary income to the recipient. Conversions of a 408(b) or traditional IRA to
a 408A 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,
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. The five-year holding period may be different for determining
whether a distribution allowable to a conversion contribution is subject to the
10% penalty tax. 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.

     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 the Company (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, 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
    qualified plans and 403(b) annuities);

(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.

     After 1997, 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;

                                        8
<PAGE>   49

(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.

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)  should begin to be paid when the 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.

     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 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, 408(b) IRAs, SEPs and 457 Plans do not apply to 408A "Roth"
IRAs during the owner's lifetime, but generally do apply after the owner's
death.

     A beneficiary 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.

     Non-Qualified Contracts. Tax laws do not require commencement of
distributions from Non-Qualified Contracts 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

                                        9
<PAGE>   50

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.

     408(b) IRAs. Funds may be transferred tax-free to a 408(b) IRA Contract,
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 403(b) Annuity Contract or 401(a) or 403(a) Qualified Plan from this
"conduit" IRA if no additional contributions have been made to that 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; and

(ii) are not married filing separate returns.

     Special, complicated rules governing holding periods, escape from 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.

     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 describe generally how under certain conditions we
will allow you to exchange from other fixed and/or variable contracts we issue

     Assume the Account Value at the time of full withdrawal is $50,000
(7/1/00), and the Account Value on the previous anniversary (2/1/00) was
$45,000. 10% of $45,000 ($4,500) is not subject to Surrender Charge.

     The total Surrender Charge is:


     (10,000 - 4,500) X 2% + 5,000 X 4% + 15,000 X 5% + 2,000 X 5% + 3,000 X 7%

   10% X 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 is 39,000 - 3,900 = $35,100

c. The Surrender Charge is


   (10,000 - 3,900) X 2% + 5,000 X 4% + 15,000 X 5% + 2,000 X 5% + 3,000 X 7% +

     The current yield quotation based on a seven day period 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. The 7-day Current Yield for

     An effective yield quotation above 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
compounding the base period return by adding 1, raising the sum to a power equal
to 365 divided by 7, and subtracting 1 from the result, according to the
following formula:

             EFFECTIVE YIELD = [(BASE PERIOD RETURN + 1) 365/7] -1

                   CALCULATION OF AVERAGE ANNUAL TOTAL RETURN


     Average Annual Total Return quotations for the 1, 5, and 10 year periods
ended March 31, 2000, are computed by finding the average annual compounded
rates of over the 1, 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>  <C>
                 P     =   a hypothetical initial Purchase Payment of $1,000

                 n     =   number of years
                 ERV   =   redeemable value at the end of the 1, 5 or 10 year periods
                           of a hypothetical $1,000 Purchase Payment made at the
                           beginning of the 1, 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 7% of Gross Purchase Payments 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, 5 or 10 year
period and deduction of all nonrecurring charges at the end of each such period.

                            PERFORMANCE INFORMATION

     THE PERFORMANCE OF A DIVISION MAY FROM TIME TO TIME BE COMPARED WITH THE
FOLLOWING INDICES WHICH HAVE BEEN DEEMED BY THE COMPANY RELEVANT TO THE
DIVISION:

     The performance of the AGSPC Government Securities Fund Division 4 may be
compared to 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 the AGSPC Growth & Income Fund Division 1, OCCAT Managed
Portfolio Division 3, AGSPC Stock Index Fund Division 5, AIM V.I. Capital
Appreciation Fund Division 8, Oppenheimer Capital Appreciation Fund/VA Division
10, and the Oppenheimer Main Street Growth and Income Fund/VA Division 11 may be
compared to the Standard & Poor's(R) Corporation ("S&P(R)")* Composite Stock
Price Index ("S&P 500(R) Index"). The S&P 500(R) Index is an unmanaged
capitalization-weighted index of 500 stocks designed to measure performance of
the broad domestic economy through changes in the aggregate market value of 500
stocks representing all major industries. The S&P 500 Index represents
approximately 73% of the aggregate United States equity markets capitalization.

     The performance of the AGSPC International Equities Fund Division 2 and the
Templeton International Securities Fund -- Class 2 Division 15 may be compared
to EAFE Index. The EAFE Index, which commenced in 1969, is an unmanaged stock
index consisting of more than 1,000 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 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 performance of the AGSPC Money Market Fund Division 6 may be compared
to Certificate of Deposit Primary Offering by New York City Banks, 30 Day Index
(Primary CD 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 Van Kampen LIT Emerging Growth Portfolio Division 7
may be compared to Russell 2000 Index(R) ("Russell 2000")** and S&P MidCap 400
Index. The Russell 2000 was developed in 1984 by the Frank Russell Trust 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 Trust
Company on the basis of their market size. The S&P MidCap 400 Index is market
weighted and consists of 400 stocks of domestic companies having a median market
capitalization of approximately $1.37 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 the AIM V.I. Diversified Income Fund Division 9 may be
compared to Lehman Aggregate Bond Index. The Lehman Brothers Aggregate Bond
Index is a market weighted index that contains individually priced U.S.
Treasury, agency, corporate, and mortgage pass-through securities rated BBB- or
better. The Wilshire 5000 Index consists of common equity securities, covering
all stocks in the U.S. for which daily pricing is available.

     The performance of the Oppenheimer High Income Fund/VA Division 12 may be

                                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% per annum. 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 A.G.
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%.

     The portion of the first monthly variable payout payment derived from a
Division of A.G. 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% 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% 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 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 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 three 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
a 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."

method of determining the Payout Unit value and the amount of variable annuity
